The present invention relates generally to cooking devices designed for thermal processing of food and having in its composition a vessel intended to contain the cooking bath. More specifically, the invention relates to devices of the above mentioned type, having in its composition a device for emptying the cooking bath contained in said vessel.

The invention relates in particular, but not exclusively, to devices called fryers. Indeed, in this case the cooking bath is not limited to an oil bath or a bath of melted fat, but may also represent a tub of any food material is fluid enough to be able to flow from the cooking vessel through the pouring device, and, in particular, can be a water-based liquid.

From patent US 2597695, CH 325786 and FR 2665068 known fryers having a pouring channel. However, none of these patents provides for the use of special containers for collecting oil. In the patent FR 2773976 described a deep fryer having a pouring channel and the receiving container held by the latch, accommodated in the housing of this device. The operation of such devices requires constant and stuck the aqueous attention on the part of the user due to overflow of oil from the casing of this device.

From patent US 2867164 known industrial deep fryer of the type having a cooking vessel and receiving vessel for pouring, accommodated in the housing. The cooking vessel includes a pouring channel with valve. Reception capacity for moulding installed removable on the inner surface of the door body. The transfer of this design solution in the device domestic purposes is not creating full confidence in security.

From the patent DE 19907150 a device for cooking food, the cooking vessel which contains the pouring channel, equipped with a valve having a motorized drive. The control device of the driving motor may comprise a temperature sensor that eliminates the possibility of draining the cooking vessel in the case when the temperature of the contents of this vessel is too high. This solution can be considered for devices industrial or professional purposes, but is too expensive for household fryers.

The technical problem of the invention is to improve safety device for cooking food, having in its composition a cooking vessel having a pouring device.

Another technical task of the present invention is to appreciate the live device of the above-mentioned type, characterized by compactness and efficiency.

These technical problems are solved with a device for cooking food products containing in its body vessel, designed to accommodate the cooking bath and provided with a pouring device intended for removal of the contents of this cooking vessel to the receiving vessel for pouring, is made detachable with respect to said housing, due to the fact that the pouring device comprises a thermostatic valve containing temperature-sensitive mechanical body with a certain mobility depending on the temperature. This temperature-sensitive mechanical organ may represent, for example, a bimetallic plate, item, made of an alloy having the property of storing geometric shapes, or wax piston. Due to this mechanical body, rolling, depending on the temperature, thermostatic valve can represent an open configuration or a closed configuration, depending on the actual temperature level. Thus, pouring the contents of a cooking vessel may be blocked in the case when the temperature of the cooking bath exceeds some threshold value. This solution allows you to increase the traffic signals is in the use of this device, limiting the risk of burns in the manipulation of the receiving tank for pouring. In addition, in this case to implement the receiving tank for pouring can be used for less noble and, accordingly, less expensive materials, such as polypropylene. Reception capacity for moulding may be located in the device or may represent a base on which you install this enclosure. The cooking vessel may be made removable and can be placed in the dishwasher. Thermostatic valve device pouring ensures the safety of independently control the opening and closing of this device by the user. In addition, this solution is less expensive because it does not require the use of the engine to actuate thermostatic valve.

Preferably thermostatic valve is located in the channel opening at the bottom of the cooking vessel. This design decision allows to facilitate the process of emptying the cooking vessel.

Preferably before mentioned thermostatic valve placed the filter.

This technical solution allows to prevent sediment build-up in the cooking bath, touched on the functioning of the licensing of thermostatic valve. This technical solution allows to improve the quality of the cooking bath in that case, when consistently carried out the preparation of portions of food in the same tub.

In accordance with one method of implementation of the present invention, thermostatic valve includes tumbling bimetallic Cup. In accordance with other ways of realization of this invention can be considered, for example, thermostatic valve, containing the wax piston or a part made of the alloy having the property of storing geometric shapes.

Preferably, the pouring device comprises a second valve containing a movable item overlap is controlled by using the drive arm. This design decision allows the user to control the emptying of the cooking vessel.

In this case, thermostatic valve is preferably located between the cooking vessel and said second valve. This design decision allows us to consider thermal contact between the cooking bath and a movable body depending on the temperature of thermostatic valve. This implies a more rapid response of the valve in the process of increasing the temperature when heated, and in the process of its reduction when is hladini.

In this case, preferably, the control handle results in movement of the mentioned movable part overlapping with the aid of the control mechanism mounted on the receiving tank for pouring. Thus, in the absence of this receiving tank for pouring the user is not exposed to risk to make emptying the device. In addition, installation of the control mechanism at the receiving containers for pouring facilitates the implementation of the removable cooking vessel. Reception capacity for moulding can be accommodated in the housing of this device or may represent a base on which is mounted the casing of this device.

Preferably the handle, operate the drive mechanism is mounted on a receiving tank for pouring. This technical solution allows to simplify the design of this device. Alternatively, the handle can be mounted, for example, in the case of this device.

Preferably the housing of the device includes a side opening into which may be introduced, at least partially, collecting bottle for pouring. Alternatively, the housing of the device may be, for example, is made of two parts, namely the upper part of the covering, at least partially, cooking with the court, and the bottom part that holds the receiving container for pouring, and referred to the upper part of the housing removed in order to access the pit.

In this case, the handle preferably is mounted on the external side surface of the receiving tank for pouring. This technical solution allows to simplify the design of this device. Alternatively access to the control handle may be provided, for example, through the hole made on the body surface.

Preferably the cooking vessel is made detachable with respect to the casing of this device.

The invention will be better understood from the following description, non-limiting example of implementation, where there is reference to the application drawings, on which:

Figure 1 - schematic view illustrating the cooking device in accordance with the invention in position designed for pouring the contents of the cooking vessel, and the outer body of this device is shown by the dotted lines;

Figure 2 is a partial schematic view of the device shown in figure 1, in the position after emptying the cooking vessel, illustrating a safety device designed to prevent the execution of the TLD the successive operations of pouring without removing the receiving tank for pouring;

Figure 3 is a partial schematic view in cross section of the device shown in figure 1, in the position after emptying the cooking vessel;

4 is a partial schematic view in cross section of the device shown in figure 1, in the position intended for pouring the contents of the cooking vessel.

The device, shown schematically in figure 1-4, is a fryer, comprising a housing 1 having a top opening, in which is inserted the cooking vessel 2, is designed to accommodate the cooking liquid. This top opening of the housing may be closed by a cover which is not shown in the Appendix figures. The housing 1 also has a side opening into which is inserted into the collecting bottle for pouring 3.

How this can be best seen in figure 3 and 4, the cooking vessel 2 contains the pouring device 10. This cooking vessel 2 is preferably removable and contains tools type 8 feet, designed to allow the installation of this vessel on the kitchen work surface. If desired, an electric heating means 9 can be fixed under the cooking vessel 2. Alternatively, the implementation of these electric heating means can be accommodated in the housing 1, or inside the cooking vessel 2.

The pouring device 10 includes a channel about the conduct 15, coming out of the bottom of the cooking vessel 2. From the cooking vessel channel 15 is protected by a filter 14. Spring valve 20 closes the lower part of the channel 15. thermostatic valve 16 is placed between the filter 14 and the valve spring 20.

The channel 15 is formed by a housing 11, which is the preferred way is made of plastic material, resistant to high temperatures in the cooking bath, for example from a material Amodel, resistant to temperatures up to 250°With, in the case of deep fryers. This housing 11 is fitted with a removable manner with respect to the cooking vessel 2. The gasket 19 is inserted between the cooking vessel 2 and the housing 11. This sealing gasket 19 is the preferred way fixed to the body 11 in order to prevent its loss in the process of dismantling the device splashing or not to forget again to install the gasket in the process of re-mounting the pouring device.

The filter 14 has a removable manner with respect to the cooking vessel 2 and to the housing 11. In accordance with an example implementation, illustrated in the application drawings, the filter 14 is rigidly connected with the rim 13, which are secured by means of connections, bayonet type on the housing 11. This rim 13 is removable manner in the recess of the bottom part of the cooking with the UDA 2 and is fixed on the rotational movement relative to that of the vessel 2. The upper part of the housing 11 is inserted into the hole made in the bottom part of the cooking vessel 2, and includes inclined surfaces 11a, interacting with inclined surfaces 13A of the rim 13 for forming the above-mentioned connections, bayonet type.

thermostatic valve 16 includes a flip bimetallic Cup 17, fixed on the bottom surface of the perforated plate 18 overlying the upper end of the housing 11. This plate 18 may be, for example, expanded in the internal cavity of the housing 11.

Tumbling bimetallic Cup 17 forms a temperature-sensitive mechanical body with mobility as a function of temperature. This Cup 17 are presented in figure 3 and 4 in the open position, corresponding to its position at low temperature. The Cup 17 in the position corresponding to the high temperature, closes the channel 15. The transition temperature between a position corresponding to a high temperature, and a position corresponding to a low temperature, the cooling process has a value, for example, about 90°With, in the case of deep fryers.

In an example implementation, this Cup is made of a bimetallic plate and has a diameter of 30 mm In the closed position, the Cup 17 is bent in a downward direction and its peripheral part is in focus in the internal Kohl the eve of the ledge 12 of the housing 11. Thus, in this case, thermostatic valve 16 is closed. In the open position of the Cup 17 is bent in the other direction, i.e. in the upward direction, and forms a passage to the holes of the perforated plate 18. This liquid gets the opportunity to go through this thermostatic valve 16.

Spring valve 20 includes a movable item overlap 21, equipped with a toroidal peripheral sealing gasket 22. This part 21 is mounted on a spring 23 and abuts against the lower surface of the said Cup 17. The resting position of the spring 23 corresponds to the view shown in figure 3, where the spring-loaded valve 20 is in its closed position.

Reception capacity for moulding 3 is large enough to accommodate the cooking bath contained in the cooking vessel 2. This reception capacity for moulding 3 contains a collection tank 30, closed the lid 31. Reception capacity for moulding 3 is an outer side surface 32. If desired, this side surface 32 can be manufactured at least partially from a transparent or translucent material in order to provide the user the ability to control the degree of filling of this receiving tank for pouring 3.

Reception capacity for moulding 3 also contains mechanisms is 40 management of emptying, preferably mounted on a collecting tank 30. This control mechanism 40 includes a movable part of the control 42 mounted around the feed channel 41, an opening in the side wall 33 of the tank 30. The movable part of the control 42 is funnel 43 and the Cam 44 that is designed to actuate the aforementioned spring-loaded valve 20. The movable part of the control 42 is connected with the control handle 45 mounted on the outer side surface 32 of the receiving tank for pouring 3. This control arm 45 causes the item 42 in the rotational movement. The side wall of the channel 41 is the filling opening of the 46 covered by a toroidal sealing gasket 47 thus, in order to ensure tightness between the channel 41 and the movable part of the control 42. Control handle 45 can move between the so-called operational provision of this cooking device corresponding to the types shown in figure 2 and 3, and the so-called pouring position corresponding to the types shown in figures 1 and 4. In the pouring position, as is best seen in figure 4, the funnel 43 is located above the filling opening of the 46 and the Cam 44 has a pushing effect on the spring-loaded valve 20.

The proposed device for cooking food is composed of p is adahrandell device 25, designed to prevent extraction of the receiving tank for pouring 3 in the case when the valve 20 is in the open position. For this purpose the lower end of the channel 15 is a longitudinal slot 26 and the Cam 44, partially placed in the funnel 43 is inserted into the slit 26 in the process of pivoting movement of the movable part of the control 42 in direction pouring, as shown in figure 4. The control mechanism 40 contains, therefore, the tongue 27 that is designed to interact with a cutout 28, owned by the valve 20, in the case when this valve is moved to open position, and the said tongue 27 formed with the side surfaces of the Cam 44, and the aforementioned cutout 28 formed by the slit 26.

The proposed device also incorporates other safety device 50 that is designed to prevent the possibility of two one after the other operations of pouring.

For this mobile safety item 51 is placed between the housing 1 and the receiving tank for pouring 3. This item 51 is directed in its longitudinal movement by means of guide lugs 52. Longitudinal movement of the workpiece 51 is limited to retaining lugs 53. The upper flexible plate mounted on the workpiece 51, is intended for entry in the emphasis with which my capacity for moulding 3 in the process of placing the container in the housing 1, and then for entry into the fence with this receiving tank for pouring 3 in the case when the part 51 is blocked by one of the lugs 53.

Part 51 includes the first Cam 55, which is designed to interact with the tab 48 extending from the movable parts of the control 42, in the case when the control handle 45 is moved to the pouring position after installation of the receiving tank for pouring 3. This item 51 also includes a second Cam 56 that is designed to interact with the said presser foot 48 in the case when the control handle 45 is moved to the operating position after pouring the contents of the cooking vessel. Item 51 includes a locking stop 57, designed to block pivoting movement of the movable part of the control 42 in the case when the control handle 45 is moved to the pouring position after the new use and without removing the receiving tank for pouring 3.

The proposed device in this embodiment, its implementation operates as follows.

After the cooking vessel 2 installed in the housing 1, the device is ready for cooking food. When collecting bottle for pouring 3 is located at its place in the body 1, the user can control the pouring through the handle 45. However cool the choke 44 is slit 26 and pushes the movable part overlapping spring 21 of the valve 20.

However, in accordance with the invention pouring in this case cannot occur, since the inverted bi-metal Cup 17 is in the position corresponding to the high temperature. This thermostatic valve 16 is in the closed position. After the temperature of the Cup 17 in contact with the cooking liquid, reaches a threshold value corresponding to its turnover, thermostatic valve 16 is opened.

The opening temperature of thermostatic valve 16 in the cooling process allows you to choose for the manufacture of the receiving tank for pouring and/or control mechanism such materials, temperature resistance are limited. Also reduced is the danger for the user of burns during manipulation with the receiving tank for pouring 3.

Spring valve 20 prevents the emptying of the cooking bath in the case where the receiving tank for pouring 3 is not installed in the housing 1. After collecting bottle for pouring 3 placed at the destined place, the user rotates the handle 45 and the Cam 44 pushes the movable part 21 of the valve 20. The contents of the cooking vessel can be moved in the receiving container for pouring 3, provided that thermos is eticheski valve 16 is in the open position.

The safety device 25 allows due to the occurrence of the latch 27 in the cutout 28 to prevent the extraction of the receiving tank for pouring 3 of the housing 1 in the case when the control mechanism 40 is in the pouring position and the Cam 44 has a pushing effect on the movable part 21 of the spring valve 20.

The safety device 50 does not allow re-operation pouring in if collecting bottle for pouring 3 was not removed at least partially from the housing 1, and then again inserted in its place, thanks to the movements of the parts 51 in the translation process of the control unit 40 from the operating position to the pouring position and back, and also in the extraction process and subsequent replacement in place of the receiving tank for pouring 3.

As a variant implementation of the control mechanism 40 by the operation of pouring may not be rigidly connected with a reservoir tank 30, and may be, for example, is mounted on the cover 31 of the receiving tank for pouring 3.

As an embodiment of the control handle 45 may be installed on the side surface of the receiving tank for pouring, located inside the housing of this device in the case when this reception capacity installed in place in the enclosure. the ri access to the control handle can be carried out via the outlet, made in the side wall of the housing.

As an embodiment of the control handle 45 may be mounted on the housing 1 of the device, for example, against the side of the recess in the casing, which allows the insertion of the receiving tank for pouring. The connection between the control handle and the control mechanism is in the process of inserting this receiving tank for pouring into the device.

As an embodiment of the collecting bottle for pouring 3 may constitute a base on which a removable sets the body of the device, comprising a cooking vessel.
