Description

The present invention relates to a refrigerator comprising a drawer.

In refrigerators, food products and various containers are placed on shelves and / or in trays. In particular, breakfast products, such as cheese, olives, butter, jam, which are usually consumed infrequently, several times and for different periods of time, are stored in small, closed bowls. However, the transfer of these small bowls, the number of which is by no means small, one to the table and back, from the table to the refrigerator, can be a time-consuming process for the user.

Therefore, boxes were developed for carrying small breakfast plates at the same time. The implementation of this development is described in German patent application DE No. 10339942. This document describes a box that can slide along the rails on the sides of a shelf. The box lid is also mounted by sliding between the rails. In this embodiment, a separate cover is provided for insulating the interior of the box and a special rail for mounting this cover.

In the device described in US patent No. 4944566, an additional storage system can move along the wire rails under the shelf. Guides are attached to the shelf by means of brackets.

U.S. Patent Application No. 20033201700 describes a lid attached to a box by a lever and pivoting about a horizontal axis. When the drawer is pulled out, the lever lifts the lid, turning around an axis.

In German Patent No. 1286523, magnets are used for insulation when the box is put in place.

European Patent Application No. 520786 describes a box that moves back and forth under a shelf.

US Pat. No. 4,775201 describes a food container that can rotate around its rear side. The box in the closed position is in contact with the bottom surface of the shelf.

In addition, the sealing element used to isolate the boxes of the prior art can only be located in certain places, in particular, at the entrance and exit of the area where the box is located. This leads to the fact that isolation is insufficient.

An object of the invention is the creation of a refrigerator containing an easily movable box with a more isolated inner space.

A refrigerator realizing the object of the invention is described in the attached claims. A refrigerator is provided in the refrigerator according to the invention, which can be moved along a rail. When the drawer is at one end of the rail, it is in the loading position at a lower level, in which the interior of the drawer is accessible to the user, and when the drawer is at the other end, it is in the storage position at a higher level, in which food products, those in the box are isolated. The said guide rises upward, continuing, for example, from the front of the case back or from one side wall to the opposite, and in the storage position the top side of the box is fully engaged with the bottom surface of the shelf. The fact that the box rests against the shelf, rising from bottom to top, is the difference from the prior art layouts in which, throughout its entire movement, it slides parallel to the bottom surface of the shelf, adjacent to it. Thus, the upper side does not rub against the shelf during the movement and, therefore, does not interfere with the movement of the box. Since the bottom surface of the shelf serves as a lid for the drawer, a separate lid is not required. The volume limited by the drawer and the shelf is effectively isolated from the environment.

The guide has the form of a channel that starts in front of the body and goes to the side wall. On both sides of the drawer there are protrusions, pins, etc., mating with these guides.

There is such a distance between the guide and the rib that the box does not contact the bottom side of the shelf (does not rub against it), moving from the loading position to the storage position. Near the storage position, the guide approaches the rib so that the box can come in contact with the bottom surface of the shelf.

According to another embodiment of the invention, a sealing element is provided that surrounds the upper periphery of the box on all sides.

According to one embodiment of the invention, the guide portion near the storage position extends horizontally. The length of this section is equal to the depth of the box. Thus, the drawer remains in the storage position separately until the user pulls it out.

According to another embodiment of the invention, the guide portion extends vertically at the storage position. Thus, the box moves to the bottom surface of the shelf like an elevator, thereby removing the problem of friction. In this embodiment, a latch is used to hold the drawer in the storage position. This latch may be a groove latch, etc., or any other device for coupling the box with a shelf or case.

According to another embodiment, a lever is used that biases the portion of the sealing element from the bottom surface of the shelf due to the vacuum generated in the interior of the box in order to facilitate separation of the box from the bottom surface of the shelf when returning from the storage position to the loading position. This lever may be, for example, an elastic strip fixed inside the box and extending outward over the sealing element. Or it may be a biasing means covering a hole made in the interior of the box. When the user pulls the lever, air entering the interior through an open hole or elongated portion of the sealing element eliminates the effect of vacuum. Thus, a handle is formed, for which the user can hold the box, and also provides ease of movement.

The refrigerator (1) according to the invention contains:

- Pavilion 2),

- a door (3) covering the housing (2),

at least one shelf (6) on which food products are placed, and

- box (7), on which the shelf (6) is located (figure 1).

In addition to the aforementioned, the refrigerator (1) according to the invention comprises a box (7) having the shape of an open top box and at least one guide (4) along which the box (7) moves. The box (7) moves along the guide (4) between the loading position at a lower level, in which the top is open, and the inner space of the box is accessible to the user (Fig. 1), and the storage position at a higher level, in which the top is closed, so how the upper side is in contact with the bottom surface of the shelf (6), and the inner space is isolated (FIGS. 2 and 3). In other words, the box (7) approaches the shelf (6), moving to the storage position, and moves away from the shelf (6), moving to the loading position. The guide (4) follows the path that does not allow the box (7) to contact the shelf (6), starting from the loading position and ending with the position slightly reaching the storage position (Figs. 2 and 3).

In this embodiment, a drawer (7) in which, for example, breakfast products are stored, is inserted between two guides (4) when the user wants to place it in the case (2). The top of the box (7) is open when it is in the loading position (figure 1). The user can put any desired object in the box (7) or remove it from the box located near the front of the case (2). When the user begins to push the box (7) to the rear wall of the housing (2) (Fig. 2), the box (7) moves along the path of the guide (4), but does not touch the shelf (6). Then the box (7), moving along the guide (4), rises, approaching the storage position (figure 2). The upper side of the box (7) first approaches the bottom surface of the shelf (6) at a certain angle (Figs. 3 and 6), and then provides isolation of the inner space of the box (7), fully adhering to the bottom surface of the shelf (Figs. 4 and 7 )

According to another embodiment, the refrigerator (1) comprises a sealing element (9) surrounding the upper periphery of the box (7) on all sides, providing better insulation in the storage position. When the box (7) reaches the storage position, the sealing element (9) is wedged between the box (7) and the bottom surface of the shelf (6), providing better insulation (figure 4).

According to one embodiment of the invention, the guide (4) has the form of channels made opposite to each other on the side walls of the housing (2) by making recesses and protrusions. In this embodiment, the box (7) contains two separately located protrusions (8), one on each side, which engage with the guide (4) (Fig. 5). The protrusions (8) facilitate the movement of the box (7) along the guide (4).

According to one embodiment of the invention, the guide portion (4) near the storage position extends horizontally (Figs. 1, 2, 7). The box (7) engages with this horizontal section and remains in the storage position until the user exerts a force.

According to another embodiment of the invention, the guide portion at the storage position extends vertically (Fig. 8). Thus, the box (7) moves vertically to the bottom surface of the shelf (6). In this embodiment, the refrigerator (1) comprises a holder (11, 110) holding the box (7) from sliding down the guide (4) under the action of gravity (Figs. 8 and 9). The holder (11, 110) may be a latch groove, etc. for coupling the drawer (7) with the shelf (6) or the housing (2).

According to another embodiment of the invention, the refrigerator (1) contains a movable lever (12) for violating the vacuum arising in the interior of the box (7), which interferes with its movement when moving out of the storage position, and for supplying air to the box (7) (FIG. 8 and 9). In this embodiment, the lever (12) has the shape of a strip protruding from the box (7) over the sealing element (9) (Fig. 8). According to another embodiment, the box (7) comprises an opening (not shown in the drawings) made in the interior space, and a lever (12) opens and closes the opening. When the user pulls the lever (12), air entering the interior through an open hole or from the elongated portion of the sealing element (9) helps to separate the box (7) from the storage position.

According to another embodiment, the box (7) comprises more than one compartment (10) (FIG. 5) located side by side. In these departments (10) place products. Compartments (10) can be made in one form together with a box (7) or made separately from a box (7).

Using the refrigerator (1) according to the invention, the user can store food products in a drawer (7) without using a separate lid.
