The present invention relates to the field of electrical apparatus for cooking, in particular, to multi-function household food processor, called mixers and intended for the preparation of liquid food products. The present invention relates to a vessel equipped with a removable cover closing and containing means pivotally attaching the cover to the vessel.

This vessel is designed, in particular, to join a household food processor which food products are finely ground, mixed and/or transferred to the state of emulsion using a suitable tool, mounted on the drive shaft, which stood in the center of the bottom part of the vessel and driven in rotational motion by means of the electric motor. It is necessary, therefore, to cover properly closed the vessel to prevent the exit of food from the jar during processing. It is also necessary that the opening and closing of the cover was quite simple and easy, and that this cover does not interfere in the process of extraction of products from the vessel.

The current level of technology in this area known domestic food processors, in which the lid of the vessel is locked on the vessel or on the housing of the apparatus when p is power clamping jaw. Devices of this type are characterized by a high cost of manufacture. Also known domestic food processors, in which the cover is locked on the vessel using a bayonet closure system. However, this method of closure is less convenient.

In U.S. patent No. 4111372 disclosed domestic food processor, in which the means pivotally attaching the cover formed by means of a stud protruding from the cover and inserted into the longitudinal cut is made on the vessel. To insert such a thorn in the neck is quite difficult, and this operation requires a good eye and some skill. In addition, this method of communication cover with a vessel can cause problems ensure tightness.

In European patent No. 0556467 uncovered food processor, cover which is hinged to the vessel by means of a hinge. In European patent No. 0812560 described lever pivotally attached to the outer part of the vessel with which the cover is connected removable manner that requires the manufacture of two separate parts.

It can be stated that currently, there are pivotally connected to the vessel a food processor covers, and covers that are associated with the vessel removable manner, and a cover associated removable way with lever swivel. However, never disclosed roofs is a, which is also pivotally connected and associated removable way with the vessel, while providing a relatively simple installation of the cover, as well as reliable and easily controlled close the lid on the vessel and using a minimum number of parts, which reduces both the number and duration of operations of the Assembly of this unit.

The technical result of the present invention is to simplify the use of electrical apparatus for cooking, reducing the number of to-be-manufacture of parts and reduction due to this time of the installation of electrical apparatus.

This result is achieved in that the working chamber for electrical apparatus intended for cooking, contains the vessel and the lid, which contain tools swivel having two complementary surface nesting, one of which is rigidly connected to the cover, and the other is rigidly connected to the vessel, while these surfaces are along at least one axis of rotation sequence at least partially circular cross sections perpendicular to the axis of rotation. The advantage of the invention is that the complementary surface nesting allow you to simultaneously bind cu is a Cabinet with vessel removable manner, and to ensure its hinge joining the vessel. At least partially circular cross-section can form a circle or one or more arcs of a circle, or even around the above-mentioned forms in the case of corrugated, ribbed or provided with a thickening surfaces.

In accordance with a preferred implementation of the invention is complementary surface of the insertion are respectively covered and covering-or, in other words, convex and concave, for example, semi-cylindrical or hemispherical, with such design allows to facilitate the task of the cover and vessel, as well as to facilitate their cleaning. These covered and covering the surface of the insertion with the same success can be owned by the cover and the vessel.

However, there may be considered and alternative embodiments of the invention, such for example, as a means of hinge connection formed both on the vessel and on the cover, coaxial disks of the same diameter, separated from each other and connected in close proximity to him, using the wall, overlapping a quarter of their peripheral parts.

In accordance with the preferred implementation of the present invention covering the surface of the insertion is a concave surface, passing through a maximum angle the financial sector, essentially equal to 180°. This design complementary covered and covering surfaces of the insertion allows you to remove and re-install the cover is very simple and reliable way and without prejudice to any specific direction of installation or removal of the cover. It also allows you to ensure a satisfactory guiding influence on the lid along a circular path relative to the vessel.

The preferred way concave surface nesting is rigidly connected to the vessel, and at least one area of this surface is located above a plane parallel to the upper edge of the vessel and passes through the center of curvature of this concave surface, and Vice versa, the concave surface of the insertion can be rigidly connected with the cover, and at least one area of this surface is located below a plane parallel to the upper edge of the vessel and passing through the center of curvature of this concave surface. This location allows you to hold the cover in the process of translational movement along the axis of the vessel.

In accordance with a preferred implementation of the invention is complementary surface nesting represent a hemispherical surface. Thanks to this technical solution, the cover can be Sha is Nino attached along multiple axes, converging in the center of the spherical surface nesting.

In accordance with another variant of implementation of the covered surface nesting is the free end, provided for insertion along the axis of rotation against the covering surface nesting. This solution allows you also get a removable lid of the vessel, while providing a guiding influence in the process of rotation of the cover. The concave surface can be carried out at a distance of more than 180°.

The preferred way covered or covering the surface of the insertion rigidly connected with the cover, located at the end of the lever, acting outwards. This solution allows you to make easily visible surface of the swivel. Thus, if these surfaces are not nested in one another, the lid lifts in the process of introducing engages locking means located on the merits against each other, which allows the user to know that the cover is not closed properly.

The preferred way covered or covering the surface of the insertion rigidly connected with the vessel, which is made on the handle of the vessel. On the one hand, this solution allows you to remove some distance means of the hinged connection is in the outward direction, on the other hand, this additional surface nesting may be formed corresponding element of the arm and can be thus integrated in the handle.

In accordance with the most preferred implementation of the invention, the lid of the vessel contains an annular inner or outer surface of the insertion perpendicular to the plane formed by the edge of the cover adjacent to the edge of the vessel and having, respectively, of such dimensions to be inserted inside or cover the outside opening of the vessel, and the size of this surface is perpendicular to the plane formed by the edge of the cover is smaller in its part opposite the means of swivel, than, respectively, in its part closest to the tools swivel. This or these annular surfaces of the insertion of the cap is directed towards the orifice of the vessel. This solution is useful, in particular, in the case when covered and covering the surface of investing hinge joining the lid is formed convex and concave hemispherical surface that allows you to rotate the cover around the many converging axes.

In choosing the accordance with another variant of realization of the invention the lower edge of the annular surface of the insertion contains, at least one cutout, while the inner wall of the vessel contains at least one positioning protrusion located so as to engage with the said cutout when the cover is in the closed position on the receptacle. This solution allows you to improve the function of the positioning ring surface nesting, rigidly connected with the said cover.

The object of the present invention is also an electrical apparatus for cooking food, comprising a housing, forming the basis used to accommodate the vessel, closed the lid, and the vessel and its cover provides tools swivel and locking means designed to hold the cover in closed position on the receptacle and located on the housing in such a way as to interact with the surface of the locking cap, the receptacle and its cover form a working chamber in accordance with the above-described technical solutions.

Tools swivel preferred way contain concave surface nesting, rigidly connected with the vessel or respectively with a lid, and at least one area of this surface is located above or below the plane passing through the center of curvature of this magnetospheres and through the fulcrum means of the locking surface of the locking cap, when the locking block pivotally attached to the cover on the receptacle in the closed position. This solution allows you to get locked in two points.

Also preferably, the means of locking rested on the surface of the cover in the area diametrically opposite the means of its hinge connection. This solution allows you to provide an effective locking of the cover in only two points, namely by means of the locking means and the hinge joining the lid.

Also preferably, the means of locking rested on the top of the lid. This solution allows you to simplify the implementation of the device.

Other advantages and features of the invention will be better understood from the following description of non-limiting examples of variants of realization of the vessel, equipped with a cover, which is an object of the present invention, where reference is made to the application drawings, which depict the following:

figure 1 is a schematic perspective view of the vessel when the lid is closed and locked on the vessel;

figure 2 is a schematic perspective view similar to the view shown in figure 1, when the cover is closed, but unlocked;

figure 3 isone schematic perspective view of the vessel, showing the cover removed from the vessel by means of rotation about rotation;

figure 4 is a schematic perspective view of the vessel showing the cover separated from the vessel;

figure 5 is a schematic view of the receptacle with the cover in section along the line V-V shown in figure 1;

6 is a schematic front view of the first variant implementation of the invention, represented in figure 1-5;

7 is a schematic side view in section of a second variant implementation of the invention, represented in figure 1-5.

The vessel 1, is illustrated in figure 1-5, is a working vessel household food processor, bottom part which is connected with the means 2 turn the rotary working tool (figures not shown)intended to enter into engagement with the means of bringing into rotational motion (figures not shown). Since the present invention relates to a working chamber containing vessel 1 and the lid 3 for closing it, the design in General, and the drive mechanism of this domestic food processor are not part of this invention, and their description is not necessary for understanding the invention.

As can be seen in figure 5, in its closed position the cover is ka 3 is held against the edges of the holes 1A of the vessel 1. The gasket 4 is placed in the annular groove carried out under the cover 1, is used to provide sealing between the edge 1A of the vessel 1 and the lid 3. Means locking generated by disk 5 mounted to rotate on the upper part of the housing 11 of this domestic food processor, serve to hold the edges of the cover 3 against the edge 1A of the vessel 1. Disc 5 lock contains a cutout 5A, corresponding essentially to the chord of the circle formed by this disk 5. In the case when the disc 5 lock is rotated to the position illustrated in figure 1, it covers the surface 3A of the locking performed on the upper surface of the cover 3 (Fig 3 and 5), while rotating the disc 5 lock 90° for his transfer to the position illustrated in figure 2 and 3, the cutout 5A is translated in position against the surface 3A of the locking cover 3 so that the disc 5 lock no longer overlaps the surface 3A of the locking cover 3 and has secured the release of this surface.

In diametrically opposite positions with respect to the just described device locking the cover 3 contains this implementation radial arm 6, which ends with the surface 7 of the insertion of forming hemispherical section, the convex surface is which is inserted into the complementary surface 8 of the insertion, forming a concave hemispherical section of the same radius as the radius of the convex section of the hemispherical surface of the cover, and mentioned concave surface 8 of the insertion in the example considered here the implementation is made on the upper end of the arm 9, which serves to capture the vessel 1.

These two complementary surfaces 7, 8, invest in one another, form tools 10 swivel between the vessel 1 and the lid 3, which allow you to rotate the lid 3 relative to the vessel 1 in the case when the disc 5 lock releases the lid 3. These hemispherical surfaces of the rotation of the lid 3 relative to the vessel 1 can be carried out not only around a certain axis of rotation, but also around multiple axes of rotation, converging in the center Of curvature of these hemispherical surfaces 7, 8 nesting. In addition, putting each other of the two surfaces forming means 10 swivel, is lightweight, and the center of the convex surface is directed toward the center of the concave surface with the edges of the concave surface.

As is clearly illustrated, particularly in figure 5, it can be seen that the concave surface 8 of the insertion of rigidly connected with the vessel 1 contains a site located above the plane passing the th through the center Of curvature of the concave surface and through the fulcrum means 5 locking positions on the surface 3A of the locking cover 3, when the locking block cover 3, hinged to the vessel 1 in its closed position.

Alternatively, the implementation is obvious that you can swap the convex and concave surface, forming a convex surface on the handle 9 of the vessel 1 and a concave surface on the lever 6 of the cover 3. In this case, at least one portion of the concave surface of the insertion of rigidly connected with the cover 3, will be located below the plane passing through the center Of curvature of the concave surface and through the fulcrum for holding the cover 3 in the vessel 1 in the position it is locked by means of the drive 5 of the lock.

As illustrated in figure 4, due to the described means of the hinge connection of the cover 3 with the vessel 1, the cover 3 can not only be rotated in the vessel 1, but it can also be detached from this vessel and then re-installed without difficulty separating from each other and, accordingly, putting one another hemispherical surfaces 7, 8 of the insertion of that is no problem, considering the size of these surfaces, and because they preferred way are, as can be seen in the illustrated implementations, some the distance from the edge of the vessel 1.

Because the use of the hinge balls is the second type between the lid 3 and the vessel 1 gives more freedom of movement, reinstall the cover 3 in its place in the locking position may in some cases be a problem in regard to the orientation of the cover 3 toward the locking position. To solve this problem, as can be seen in figure 5, the lower surface of the cover 3, the preferred image contains an internal ring surface 3b of the insertion, which runs perpendicular to the plane formed by the edge of the cover 3 adjacent to the edge 1A of the vessel 1, forming a kind of skirt so that it was possible to properly Orient the cover 3 in the vessel 1 in the process vessel closure of this cover. The preferred way the height of the inner annular surface 3b of the insertion is somewhat smaller in the vicinity of the disk 5 locking positions than in the immediate vicinity of the convex or concave surface 7, 8 of a turn, to facilitate closing the cover 3 by turning around the mentioned 10 rotate or swivel.

The inner surface of the cover 3 also includes an outer annular surface 3C of investing that is designed to be inserted at least partially around the upper edge 1A of the vessel 1, and which would also serve as a guide when installing the cover 3 of the vessel 1. The preferred way the height of the outer annular surface is STI 3C insertion is slightly lower in the immediate vicinity of the convex and concave surfaces 7, 8 of a turn than in the immediate vicinity of the disk 5 locking positions, to facilitate vessel closure lid 3 by turning around funds 10 rotate or swivel.

The gasket 4 is installed, for example, in a groove formed by using the above-described annular surfaces 3b, 3c of nesting.

In accordance with another variant of realization of the rib 1b positioning can be performed in a protruding manner on the inner wall of the vessel 1 (figure 5). Cutouts 3d can also be made in the bottom edge of the annular surface 3d of the insertion of the cover 3. These cutouts 3d positioned so as to correspond to the ribs 1b, so that these ribs 1b consisted in the notches 3d, when the cover is in position suitably secured on the vessel. In this case we are talking about additional tools that are made on the inner annular surface 3b of investments in order to ensure installation of the cover 3 in the vessel 1 to a position accurately corresponding to the position providing its lock.

It goes without saying that the invention is not limited to the surfaces 7, 8 of the insertion of a hemispherical shape and is also applied to the surfaces of the insertion, which may be cylindrical, semi-cylindrical, or, more generally, to the surfaces of the insertion, the holding surface, representing the axis of rotation of a sequence of sections, at least partially circular.

The present invention encompasses, in particular, the embodiment shown in Fig.6, which covered the surface of the insertion is formed by a pin 7′performed at the end of the radial arm 6′ caps 3′whereas in the handle 9′ will be executed through a cylindrical hole 8′forming a covering surface investing 10′ swivel. Thus it is enough to enter the pin 7′ hole 8′as shown by the arrow F, attach the lid 3′ to the vessel 1′. The input part of the cylindrical hole 8′ may contain a guide cone 8′and designed to facilitate the introduction into this hole pins 7′. A preferred way, the length of the pin 7′ exceeds the length of the holes 8′and this pin has at its end protrudes in the lateral direction of the tooth 13, adapted to slide in the groove 14 made in the hole 8′in the process of introduction of the pin 7′ hole 8′ and to pirania in the side wall of the arm 9′ vessel 1′ during rotation of the lid 3′. This tooth 13 and the groove 14 is made, for example, to allow installation of the cover 3′when the cover is vertical Polo is giving.

As an additional option, the implementation is not a necessary condition so that the pin, forming a covered surface nesting, represented generally cylindrical shape and that the hole forming a covering surface investing swivel, formed of a cylindrical support. 7 shows another embodiment in which the hole 8′′forming a covering surface investing 10′′ swivel generated by the lower surface of the upper rack 15, which connects the handle 9′′ vessel 1′′and in which the pin 7′′forming a covered surface nesting, comes out of the radial arm 6′′ caps 3′′and presents a flat surface or chamfer 16 in the zone not affected by rotation. A tooth (not shown in Fig.7) may also be provided on the end of the pin 7′′ to engage with the handle 9′′resistant 15 or vessel 1′′. The handle 9′′ may also be some backlash from the vessel 1′′more significant in the lower part, in order to facilitate the insertion of the pin 7′′.

Forming a covered and covering surfaces investing swivel does not require the part is a segment of a circle, as it takes place in a variant implementation of the invention, represented in figure 1-5, or plot a straight line parallel to the axis of rotation, as is the case in implementations presented on Fig.6 and 7, but may, in particular, to provide a plot of a straight line intersecting the axis of rotation for the formation of this conic section, or may represent a cross section for the formation of the land in the form of the ellipsoid.

Sections covered surfaces of the insertion can be circular, i.e. passing on 360°in the case of surfaces of the insertion of having constant and/or decreasing cross-section, is inserted in the direction corresponding to the axis of rotation of the funds swivel. However, the maximum semi-circular section, which allow insertion along a direction different from the direction of the axis of rotation of the funds swivel, are much less shy use, and the user can simply attach surface of the insertion of one another. The preferred image of the surface of the investments in this case are relative to the axis of rotation of the cross section, the diameter of which varies gradually so that without special effort by the user to direct surface nesting in% the magnetic resonance installation swivel.

The surface of the locking cap, the preferred way is located diametrically opposite with respect to the means of swivel in order to simplify the implementation of a locking means of this apparatus. However, this surface locking does not necessarily have to be performed on the upper surface of the lid.
