The technical field to which the invention relates.

The present invention relates to a cooking unit for making beverages, using capsules containing the ingredient of the food product for preparing a beverage or a similar food. The brewing unit has simplified the concept and lower cost compared to existing cooking units.

The level of technology

The problem is the installation of the capsule in the device at a desired position and closing device around the capsule to complete the cooking process. Typically, the capsule should be placed by the user on the support for the capsule or into the housing, after which the device is closed around the capsule manually or automatically.

It is important to correctly position the capsule, so that the device is properly closed around the capsule, providing, thus, a proper seal to create the necessary conditions for extraction. Download the capsules should be simple without using the method of trial and error regarding the correct location of the capsule in the device. The load must also be performed quickly and does not require extra manipulation. There are devices that offer the insertion of the capsule in a vertical plane and moving parts used for extraction or pouring, along a horizontal plane is t around the capsule. Such systems have the advantages that loads from the top drive to enable rapid loading. The location of the capsule is performed by moving the movable part, which pushes the capsule to another part, for example the water heater. However, these devices are difficult to manufacture, and they are not suitable for cheap coffee makers of the initial level on the market of consumer goods. Therefore, as a rule, are intended for the market of specialized goods, such as restaurants, bars or institutions. For example, application WO 98/4748 relates to a device for the extraction of pre-measured inserts, in which the insert is inserted vertically, while the extraction is performed in the horizontal direction. The disadvantage of this device is that it contains two movable parts for extraction, which complicates the principle of the mechanism.

WO 2005/004683 relates to a brewing device for preparing a beverage from a capsule, comprising: a first part; the second part, which can move relative to the first part; a housing for the capsule and education, in the closed position of the movable part near the fixed part, the provisions of the extraction of the capsule along an axis in the above case; the part for the insertion and location of the containing means for guiding capsule ustanovlena so, to insert a capsule under the action of its own weight and be placed above the capsule in the intermediate position; the system pouring drink; and a second movable portion that is designed to move the capsule from the intermediate position to the extraction, when the device is closed.

EP 1721553 describes the brewing unit for coffee machines that use capsules. The unit has a front part with an outlet opening for the release of drink and a rear portion with an inlet opening for the inlet of hot water. The front part and rear part are mounted between a pair of opposing guide elements with ribs. The front part can be moved between the guide elements to move toward the rear and education with the rear part of the cooking chamber for placing capsules, subject extraction, resulting in the car remains free space in front of the front element between the guide elements.

EP 1659547 relates to a machine for making infusions, in particular espresso coffee. The machine includes a chamber for infusion in the cooking unit, which has a movable front part with the return spring and the discharge tube for the production of the drink, which extends through the outer body of the node. Movable front part communicates with the rear part, which can move in the abuse and you can push on the mobile front to compress the return spring, resulting in a discharge tube to slide through the outer body of the node. The pods passes through the outer casing into the chamber insisting on rigid conduit for supply of pods, and then the pod is sent to the camera for processing with the outer sleeve on the movable rear part of the cooking unit, which has a section type of the Cam to move back. This configuration creates a few problems. The pods should move during closing the cooking chamber, and this can lead to blocking, and also complicates the design tools that hold the pods. In addition, opening and closing the cooking chamber at the same time associated with linear movement of the movable rear casing, a movable front part of the housing and the outer discharge tube body, which increases the risk of exceeding the requirements for the component directions and jamming or improper alignment of the various parts that are linearly moved relative to each other. Liquid system contains a mobile node, which complicates the Assembly of a liquid system. In the case when after the extraction of the brewing unit re-opened for removal of pods, water under pressure in the chamber for infusion may be ejected from the housing to the outside. In addition, the car remains free volume between arenim element and the housing, when the discharge tube is in the retracted position.

US 3,260,190 and WO 2005/072574 describe coffee maker with removable section for placing cans of coffee in the desired position. The section can be moved with the slide in the coffee maker and lift in the direction of design for injection of water. WO 2006/023309 describes the coffee maker with a sliding section for the introduction of the cartridge into the machine with coffee. The section can be moved between the open and closed position and has two polyosoma cartridge that can be pivoted towards each other to form the cooking chamber when the drawer is in the closed position, and turn on each other when the drawer is ejected from sliding out of the car. US 6,966,251 describes the maker having horizontally moving section for placing the capsule in a desired position. During the move, sliding in the car section can be moved up in the direction of the fixed holder for capsules for education of the cooking chamber for capsules. EP 1566126 describes the coffee maker with a vertical cooking unit for placement of the pods of coffee. The brewing unit has a fixed upper part and a movable lower portion for holding pods, which can be pulled up to cover the cooking unit and lowered for insertion or removal of the pods.

Detailed description

The first embodiment of the invention is described with reference to figa, 1b and 3-6.

Figa and 1b illustrate a machine for preparing beverages with the main body 80 and the cooking unit 1 having a screw closing mechanism; design features of the cooking unit 1 shown in Fig.3-6.

The brewing unit 1 contains the node holding the capsule with the exhaust pipe 14 for the production of the drink, with the first mobile node 3 and the second stationary node injection water inlet hole for water inlet or line 25 in the housing 80. Each node 2, 3 forms at least part of the cooking chamber 7' to accommodate the capsule 9 ingredient.

As an option, the site of the injection water may be movable, and the node holding the capsules may be stationary or movable.

The node holding 3 has a tubular cover 11 and may be movable relative to the cooperating node 2 injection for transfer to the open position for education between nodes 2, 3 passage 4 for inserting in the brewing unit 1 and/or removal from the capsule 9 ingredient. In addition, node 3 retention can be moved in the direction to node 2 injection into the closed position for the formation of the cooking chamber 7'.

Node 3 retention can move with the tubular cap is th 11 screw movement in the forward direction 3' from the closed position to the open position and Vice versa. Node 3 retention has an outer part that is designed to capture and direct handoff to node 2 and from him in the outer and in the inner direction with respect to the end portion of the housing 80. With this purpose, the discharge tube 14 is of tubular cover 11 to education facilities for secure grip and easy turning and handoff tools 3 hold.

The brewing unit 1 is located in the upper part of the housing 80 on the lower part 85, usually limiting the cavity, which can be used for the water tank and/or collection of used capsules. As shown in figa and 1b, node 3 retention is and can be moved near the top front edge of the housing 80. Node 3 retention can move outward from the front of the housing 80 in the most remote position (figa) for inserting the capsule 9 and inside in the closest position (fig.1b) for cooking inserted capsule 9 in the cooking chamber 7'. Node 3 retention has an outer surface 11', which is in the adjacent position in the same plane with the outer surface 82 of the housing 80, which simplifies the wiping or cleaning of the outer surface of the machine for preparing beverages around node 3.

It is also assumed as an option node cooking unit that can Budwig is sterile in the vertical direction in the upper part of the machine for preparing beverages side to side of the machine or in its rear part.

The passage 4 is provided for the insertion of the capsule 9 in the brewing unit 1. If the brewing unit 1 is open, i.e. when node 3 retention is in the remote position, the passage 4 is formed between some distance node 3 and node 2 injection using a tubular cover 11 and allows you to insert the capsule 9 in the cooking node 1 through the opening 4' of the passage 4. If the brewing unit 1 is closed, i.e. when node 3 retention is moved to the closest or retracted position, the hole 4' spiral motion moves in the direction transverse to the direction 9' introduction capsules 9 in the passage 4. 4 hole'marked on fig.1b dotted line, and then completely removed under the plate boundary part, which forms the closing part 81 of the housing 80 for closing the bore hole 4'. The housing 80 and the tubular cover 11 have, in General, smooth slightly curved corresponding mating surface, so that the penetration hole 4' during the helical movement slid under the edge part 81 in parallel to them.

As an option you can include a movable closing part which moves relative to a movable or stationary bore hole.

Using such a sliding closing mechanism of passage for inserting the capsule 9, along which the hinge device type cover over the existing prior art, you can increase the security of the machine for preparing beverages. In fact, even when the brewing unit 1 is opened so as to allow the release of pressurized fluid from the chamber 7' in the passage 4, essentially in the direction 9' introduction capsules 9, the potential emissions of the hot liquid when re-opening of the cooking unit 1 in a secure manner will remain in the passage 9 with the lid 81 to reduce the pressure, so that the user will not be exposed to these emissions. In the closed configuration bore holes 4' closing part could take a little while, for example, a few millimeters, for example 0.5-5 mm or 1-3 mm, in the direction of the edges of the holes 4' to increase protection from emissions of liquid and/or steam when you open the cooking chamber 7' and a little to detain the actual opening of the passage 4 when opened.

For example, this is illustrated in an embodiment shown in fig.3b, and described below; edge bore hole 22' is removed under the closing part 81 for a short distance beyond the edge of the housing 80.

The brewing unit 1 according to the variant of execution, shown in figa, 1b and 3-6, is a unit swing type. As shown in more detail in figure 3-6, it contains node 2 injection water and node 3 retention of the capsule. Node 3 holding the capsule is mounted on node 2 vpri the swinging water, respectively spirally move or move in a spiral.

As shown in figure 4, node 3 holding the capsule is positioned so that the passage 4 to the capsule is oriented in the upper direction for receiving the capsule through the opening 4' in the direction 9' under the action of its own weight. The retaining part 2 is the front part of the cooking unit 1 and has a channel 14 supply of beverage to drink in the container. As described above, this front part can spiral to vdvinut'sā and to move in the reverse direction in the housing 80 of the machine.

Figure 3 the brewing unit 1 is shown in a disassembled form, where node 2 injection water contains a heater 5, which is in liquid communication with the rail support 6 and the holder 7 for capsules. The heater can be the fuser, which is in itself known. The yoke 7 for capsules usually has the form of a Cup to close the capsule with the help of unit 3 for holding the capsule. The yoke 7 to the capsule is inserted into the cylindrical body 8 of the guide support, which is also shown in Fig.6. Sealing means 70 may be provided for creating a watertight connection between the yoke 7 and the guide support 6. Line 25 water supply is provided at the site of injection water for the transport of water in the holder for capsules. The holder for the capsule also contains elements with holes, such as plate 10, to pierce the capsule with a view to ensuring the of water in the capsule. The yoke 7, thus, also may slightly move relative to the cylindrical body 8 under the action of water pressure. The ferrule acts as a piston to increase the tension on the edge of the capsule and these plates 13. The capsule may contain on the edge of a small sealing element, such as rubber o-ring seal, to improve the tension and facilitate the removal of the capsule from the holder for capsules.

Thus, the brewing unit 1 includes a tool opening of the capsule, for example plate 10 located in the cooking chamber 7' and is designed to open the capsule 9 through its perforations in the forward direction 3', in particular due to the closing of node 3 retention in the forward direction 3', thereby placing the capsule near the means of opening the capsule when the closing movement of node 3.

The system containing the cooking chamber of the piston type and the capsule with its own sealing element described in WO 2008/037642.

Node 3 holding capsule contains the usual tubular cover 11, which is attached on the inner element 12 retention of the capsule. Item 12 includes the inner housing to accommodate connectors of the plate 13. Cover 11 and the holding element 12 capsules still connected to each other by using the appropriate connection, such as by welding or heavy mechanical is precipitation. These plate 13 is also mounted within the element 12. The opening structure formed at the surface of the plate in the form of a number of these protrusions. This design is used to puncture item capsules, made of foil (not shown), to supply beverage from the capsule after some delay, corresponding to the rise of pressure in the capsule. Delay opening the capsules can be controlled by various parameters, such as thickness and material of the item capsules, made of foil, the shape and the number of projections, the static pressure of the pump, etc. of Course, the design of the cooking unit may be based on another principle of cooking. For example, the opening plate may not be used or be in the capsule, or may be replaced with a simple filter plate.

As shown in figure 4, the disposable capsule 9 may be manually inserted into the passage 16 of the cooking unit. The capsule has a Cup-shaped housing 91 and peelable membrane 90, which hermetically seals the housing. The capsule continues in a radial direction through the annular rim 92, which is sent during insertion of the capsule lateral slots 26 provided in the passage 4. When closing the cooking unit membrane 90 capsules in contact with these plate 13, i.e. when uradni node 3 is rotated in the direction a and the holder for the capsule when closing clicks on the plate. During closing of the upper side 93 of the casing of the capsule is pierced these elements 10 to provide injection of water into the capsule. The rim 92 capsules are also tightly clamped as the edge of the cage 7 for capsules, and these platinum 13. Waterproof closing must withstand high water pressure in the holder for capsules, i.e. at least 10 bar. During cooking, water is injected into the capsule by the high-pressure pump (not shown). The steady-state pressure in the capsule leads to perforation of the membrane in these plates. The operation of the perforation may be delayed in varying degrees, depending, in particular, from the design of the capsule and these plates. Immediately after perforation of the capsule, the beverage can be released through the perforations with the help of these plates (which has small channels/holes). The drink is collected and drained through the collecting pipe 19 leading to an outlet pipe 14 of the tubular cover 11.

Itself capsule may be made of aluminum and/or plastic. It can contain ground coffee or other food ingredients.

As can be seen from Fig.6, the node cover 11 and the holding element 12 capsules allow you to limit the forward internal volume that acts as a receiver 140 for welded liquid. This receiver can form premiato the ing the camera to save the foam and brake fluid before exiting through the discharge tube 14.

The connection node 3 for holding the capsule and node 2 for the injection of water is performed by means of a screw connection means. More specifically, the element 12 for holding the capsule has a pair of spiral or helical grooves 16, which engages a pair of radial pins 17 of the guide support 6 Therefore, as shown in figure 3, node 3 retention of the capsule and node 2 injection water are at some distance from each other, with the passage of the capsule is located at the top in order to ensure the insertion of the capsule due to its simple fall under their own weight. After inserting the capsule before closing is held in the desired position in the node for holding the capsule from the anterior side of the plate 13.

Thus, the brewing unit according to the invention can be associated with the retaining means, such as protrusions, at the discretion of the formed guide grooves for a capsule for holding capsules ingredient between nodes when the nodes are in the open position. Means of restraint at the discretion are part of the site, or can move with the node that is movable outward from the housing or inside it, as shown in the examples in the figures.

Detailed embodiments of the use of the method by which the capsule can hold svarochnoye block in a predetermined position prior to closing, described, for example, in WO 2005/004683. To close the unit with capsule and remove node 3 in the casing 80, the front node 3 is turned manually in the direction And clockwise, as shown in figure 4, in the closed position of figure 5. The closed position is achieved, for example, due to the angular displacement of a quarter turn or more, in the end, depending on the geometry of the guide means 16, 17. If you turn the front node 3 he also moves backward in the direction In spiral trajectories using pins 17, which are sent to the grooves 16. Therefore, the tube 14 for supplying beverage moves from the lateral position of figure 1 to the lower position of figure 3. The final closed position shown in figure 4, and in this position the yoke 7 for capsules exerts pressure for dense close to the edge connectors 18 of the plate 13, at the same time clamping the rim or seal capsules.

It should be noted that manual control of the front node holding the capsules could be replaced by management with the drive if the motor is built into the design of the cooking unit.

Figa, 2b, and 7 to 11, in which the same reference position denote the same elements, illustrate a machine for preparing beverages with the main body 80 and the cooking unit 1 having progressive telescopicallybecause closing along a straight line 3'.

The brewing unit 1 contains the node holding the capsule with the exhaust pipe 14 of the production of the beverage forming a first mobile node 3, and node injection water inlet hole for water inlet or line 25 in the housing 80, forming a second fixed node 2. Each node 2, 3 limits, at least a portion of the cooking chamber 7' to accommodate the capsule 9 ingredient. As an option, the site of the injection water may be movable, and the node holding the capsules may be stationary or movable.

Node 3 holding a tubular cover 11 and can be moved from interacting with the host 2 injection in open position, as shown in figa, in a machine for preparing beverages for education between nodes 2, 3 passage 22 for insertion in the brewing unit 1 and/or removal from the capsule 9 ingredient. In addition, node 3 retention can move to node 2 injection into closed position, as shown in fig.2b to form the cooking chamber 7', which are sealed around the capsule 9 in the cooking position. In addition, node 3 retention has an outer surface 11'which is provided in a position essentially contiguous and located in the same plane with the outer surface 82 of the housing 80.

Node 3 retention can move with the tubular cover 11 along rectilinear translational direction 3' of C is covered position to the open position and Vice versa.

As indicated below, a machine for making beverages has a handle 30 to move the node holding the housing 80 and out of it. However, like the previous version complete with spiral closing has the ability to provide a site that can manually move directly to the site of injection and from him in the inner or outer direction relative to the housing. For example, a mobile node can be configured as a spring-loaded pressure node, which can be moved manually similarly telescopic retractable ballpoint pen, and can telescopically move back and forth between the open and closed position at which the cooking chamber is hermetically sealed around the capsule to its extraction.

The passage 22 is provided for the insertion of the capsule 9 in the brewing unit 1. As shown in figa when the brewing unit 1 is open, i.e. when the holding device 3 is in the remote position, the passage 22 formed between some distance from each other node 3 retention and node 2 injection, using a tubular cover 11 allows you to insert the capsule 9 in the brewing unit 1 through the opening 22' of the passage 22. If the brewing unit 1 is closed, i.e. when the holding device 3 is moved to the closest or retracted position, the opening 22' is moved by Tuptalo in the direction 3', transverse direction 9' introduction capsules 9 in the passage 22. The hole 22', marked on fig.2b dotted line, and then completely removed under the plate boundary part, which forms the closing part 81 of the housing 80 for closing the bore hole 22'. The housing 80 and the tubular cover 11 have, in General, smooth slightly curved corresponding mating surface, so that the penetration hole 22' during translational motion slid under the edge part 81 in parallel to them.

7 to 11 illustrate in detail the cooking node 1 from the example of a machine for preparing beverages according to the invention, depicted in figa and 2b. Cooking node 1, shown without the tubular cover 11, similarly to the previous example contains the execution node 2 injection water and node 3 retention of the capsule. Node 2 injection water contains a heater 5, such as the fuser, which is in direct fluid communication with the rail support 6 and the holder 7 for capsules. The yoke 7 for capsules usually has the form of a Cup to close the capsule with the help of unit 3 for holding the capsule. The yoke 7 to the capsule is inserted into the cylindrical body 8 of the guide supports. Sealing means 70 may be provided for creating a watertight connection between the yoke 7 and the guide support 6. Line 25 water supply is provided in the node VP is asiania water to direct the water into the holder for capsules. The holder for the capsule also contains elements with holes, such as plate 10, to pierce the capsule to ensure the ingress of water into the capsule.

The brewing unit, in addition, contains the node 3 for holding the capsule, which contains a section 15 of the main building, which includes the upper passage 22 for inserting the capsule into the holder 7 for capsules. These plate 13 is placed inside and at the bottom of the hull. On the front side of section 15 of the housing includes a tray 19 for supplying beverage from the holder 7 with the capsule through these plate 13 in a container (e.g. a Cup) through the outlet tube 14 of the tubular cover 11.

Site 2 water injection installed in node 3 holding the capsule with the possibility of linear movement by means of two lateral pins 20, 21 located on both sides of the guide support 6, which respectively engages with a pair of guide grooves 221, 222 provided on the side of node 3 hold. The pins 20, 21 are directly connected to the lever nodes 30, 31, 32. Toggle node is connected in the axial direction along the transverse axis 34 with the pins 20, 21. Toggle node has a U-shaped handle 30 and two guide rods 31, 32, United along the axis 34. These rods continue the lever with the axis 34 in a linear direction using a small internal pins 35, 36 to the e slip on the downward directed elongated sections 23, 24 slots.

Fig and 9 illustrate the brewing unit in an open configuration with the upward arm 30. In this position the two nodes are at a distance from each other, leaving a large gap 40 that allows you to insert and place the capsule. The capsule is held by lateral protrusions 41 formed in the vertical slots 42 adapted to direct the rim of the capsule during its vertical drop. Closing the cooking unit is provided by holding and lowering of the arm in the position shown in figure 10. This leads to stretching of the guide support 6 by means of pins 20, 21 and placement of the cage 7 with a capsule of dense contact pressure of its circular edge 73 connectors on the plate 13. In this embodiment, also the site of injection water preferably is fixed, while the front of the device holding the capsule is movable and is moved in the opposite direction to the site for injection of water. It may be noted that section 15 of the housing may contain external guide pins 71, 72, which can engage with an outer casing (not shown) of the machine, to which may be attached to the brewing unit.

As an option, the site of the injection water may be moving, and the front part can be fixed.

Thus, a machine for making nabitkovskiy housing 80, and one of the nodes 2, 3 cooking unit can move or telescopically advancing from the housing 80 for insertion/removal of the capsule 9 ingredient and can get into the housing 80 to bring the cooking unit 1 in position extraction capsules or cooking.

Cooking machine according to the invention has an extremely simple concept, involving the use of fewer components. In a special embodiment, the liquid system is still mounted in the car, while the collection system of the beverage can move to closing. The advantage is that the liquid system can be made more compact in order to reduce heat loss and simplification of the production machine. For example, the heater may remain stationary in comparison with existing cooking units, in which the heater is moved from the injection head.

Due to the lowering of node 3 retention in the form of a block into the housing 80 is reduced overall length, which gives the gain in space from the front side of the machine, when node 3 retention is in the retracted position in the housing.
