Description

FIELD OF TECHNOLOGY

The present invention relates to a refrigerating apparatus, and more particularly, to a domestic or industrial walking apparatus comprising at least two storage rooms.

BACKGROUND OF THE INVENTION

Refrigerators are well known. Products requiring different storage conditions are placed in two or more compartments having different temperatures and / or humidity. A typical refrigeration apparatus comprises a freezer compartment in which the temperature is maintained below 0 ° C (in particular between -18 ° C and 0 ° C), and a refrigeration compartment in which the temperature is maintained above 0 ° C (in particular, it is 4 ° FROM). The freezer compartment and the refrigeration compartment are formed by the inner lining of the body of the refrigerator, which contains a foam insulating layer, and are equipped with corresponding doors. The freezer compartment and the refrigeration compartment can be located one above the other or next to each other.

It is also well known to those skilled in the art that the refrigerator compartment in the refrigerator is divided into one or more storage rooms so that the consumer can properly use these rooms to store various food products. So, for example, in US 7021334 B2 describes a single-row design of the refrigerator, in which the freezer compartment and the refrigerator compartment are located next to each other and in which the temperature-controlled chamber is obtained by appropriate separation of the refrigerator compartment. A temperature sensor is installed in the temperature-controlled chamber. The control unit of the refrigerator can control the temperature of the temperature-controlled chamber regardless of the freezer compartment. A temperature-controlled chamber is located at the bottom of the refrigerator compartment. The upper and lower walls of the temperature-controlled chamber are respectively provided with a foam insulating layer, thus, the temperature-controlled chamber is thermally insulated from the refrigerator compartment.

In the known refrigeration apparatus, a separating element independent of the housing of the refrigeration apparatus is used to thermally isolate a temperature-controlled chamber from the refrigeration compartment. The specified separation element has a mounting surface for accommodating a thermally insulated foam plate. However, a gap may form between the foam plate and the mounting surface, and the effectiveness of thermal insulation is significantly impaired. In addition, during installation, the foam plate may be hit by various objects and thus be damaged. Therefore, the manufacturer has to take appropriate measures to make the foam plate hidden.

SUMMARY OF THE INVENTION

An object of the present invention is to provide a refrigeration apparatus in which reliable thermal insulation is made between two storage rooms.

Thus, the present invention relates to a refrigerating apparatus comprising a first storage room, a second storage room, at least one of whose parameters is regulated independently of the first storage room, and a separation element that separates the first storage room from the second storage room storage, characterized in that the separation element contains a thermally insulated space, which is hermetically sealed and which is filled with an inert gas.

Thus, even when the foam plate is not used, the first and second storage compartments can be reliably and uniformly thermally insulated from each other.

Other individual technical features or technical features that can be combined with other individual technical features and thus be considered as features characterizing the present invention are indicated in the dependent paragraphs below.

According to a particularly preferred embodiment of the present invention, the thermally insulated space is located in a hollow glass unit that contains at least two glass plates. This improves the appearance of the storage room.

According to a preferred embodiment of the present invention, the hollow glass block comprises a first glass plate and a second glass plate, which is located below the first glass plate. The upper surface of the first glass plate is at least partially located in the first storage room, forming a support for placing products to be cooled on it.

According to a preferred embodiment of the present invention, the refrigerator further comprises a freezer compartment isolated from the first storage room, and an air duct through which cold air from the freezer compartment enters the second storage room.

According to a particularly preferred embodiment of the present invention, the separation element comprises a channel that is hydraulically connected to the second storage room and through which gas can exit from the second storage room or enter the second storage room.

According to a preferred embodiment of the present invention, the separation element further comprises a lower plate located below the second glass plate, the lower plate being at some distance from the second glass plate, forming a channel between the lower plate and the second glass plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

In the following description of preferred embodiments, the same or similar elements are denoted by the same reference numbers.

First, we consider the accompanying drawings, in particular drawings 1 and 2. The refrigeration apparatus 1 comprises a housing 15 of the refrigeration apparatus and two adjacent doors 23 that are connected to the housing 15 of the refrigeration apparatus. Each of the doors 23 is pivotally connected to the corresponding lateral side of the housing 15 of the refrigerator using one or more hinges 24 and can be rotated around an axis of rotation parallel to the longitudinal axis.

The housing 15 of the refrigerator comprises a left and right side walls 26, a rear wall 30 connecting the left and right side walls 26, the upper wall 28 and the lower wall 29. The housing 15 of the refrigerator also includes a dividing wall 27, which is located between the left and right side walls 26 and which extends substantially parallel to the left and right side walls 26. The separation wall 27 is connected to the upper wall 28 and the lower wall 29, respectively. The left and right side walls 26, the rear wall 30, the upper wall 28, the lower wall 29, and the separation wall 27 comprise a foam insulating layer (not shown) that is formed by foaming the insulating foam material.

By using the side walls 26, the rear wall 30, the upper wall 28, the lower wall 29, and the separation wall 27, the refrigerator body forms a freezer compartment 22 and a refrigeration compartment 6 that are adjacent to each other. The front sides of the freezer compartment 22 and the refrigeration compartment 6 are respectively open and closed by the corresponding doors 23. The door 23 comprises a foam insulating layer which is formed by foaming of the heat-insulating foam material. Typically, the doors 23 are closed in order to prevent the release of cold air from the freezer compartment 22 and the refrigeration compartment 6. If necessary, the user can open the corresponding door 23, for example, in order to remove food from the freezer compartment 22 or the refrigeration compartment 6. For opening and closing doors 23 provides handles 25.

The refrigerator compartment 6 comprises a separation element 4, which is removably mounted in the refrigerator compartment. The separation element 4 is located horizontally. The dividing element 4 is connected laterally to the dividing wall 27 and to the corresponding side wall 26 by insertion. Using the separation element 4, the refrigerating compartment 6 is divided into a first storage room 2 and a second storage room 3, which are independent of each other. The separation element 4 is designed to prevent the flow of air between the first storage room 2 and the second storage room 3 and for thermal insulation of the two storage rooms 2 and 3. Thus, it is possible to independently control the parameters of the storage conditions, in particular, the temperature and / or humidity, in the first room 2 and in the second room 3. In this embodiment, the first storage room 2 is located above the second storage room 3.

The refrigeration apparatus 1 preferably comprises measuring means for measuring relevant parameters (in particular, temperature and / or humidity, etc.) in the first storage room 2 and in the second storage room 3. Based on the measurement results of these parameters, the control unit of the refrigeration apparatus 1 can control the storage mode in the first room 2 and in the second room 3, respectively. In this embodiment, the first storage room 2 is used as a conventional refrigerating chamber, and the second storage room 3 is used as a temperature-controlled chamber, which can be changed over a wide range (in particular, from −10 ° C. to 14 ° C.) .

In this embodiment, an air line 11 is installed on the dividing wall 27, which is located in the second storage room 3 and which allows air to pass from the freezer compartment 22 to the second storage room 3. The air duct 11 can preferably be opened or closed by the control unit of the refrigeration apparatus 1, depending on whether supply to the second room 3 is required to store cold air from the freezer compartment 22 or not. Opening and closing of the air duct 11 can be carried out using a damper, which is located in the air duct 11 and which is connected to the control unit. Preferably, a fan is installed in the duct 11, which draws in cold air from the freezer compartment 22 when the duct 11 is open, while the temperature of the second storage room 3 decreases. In an alternative embodiment, the refrigeration apparatus 1 may comprise a separate cooling system for cooling the second storage room 3.

As shown in figures 3, 4 and 5, the separation element 4 contains a hollow glass block 7, which is used to prevent heat transfer between the first storage room 2 and the second storage room 3. The hollow glass block 7 has a flat rectangular shape and is located horizontally.

The hollow glass block 7 comprises a first glass plate 8 and a second glass plate 9 located below the first glass plate 8. The distance between the first glass plate 8 and the second glass plate 9 can be determined using a separation device 21 located between the first glass plate 8 and the second glass plate plate 9. Between the first glass plate 8 and the second glass plate 9, a hermetically closed thermally insulated space 5 is formed, therefore, the thermal resistance between a first location 2 and a second storage location for storing 3 increases to a large extent. The thermally insulated space 5 is filled with an inert gas, in particular argon or krypton. This can improve the thermal insulation of the hollow glass block 7 and prevent moisture / condensation / dew from appearing in the hollow glass block 7. The hollow glass block 7 preferably comprises a sealing device (not shown) located along the separation device in order to prevent inert gas leakage and ingress air into a thermally insulated space 5.

The dividing element 4 comprises a frame 30 extending along the edge of the hollow glass block 7. The frame 30 has an opening 31, the shape of which corresponds to the shape of the hollow glass block 7, however, the size of the hole is slightly smaller than the size of the hollow glass block. Therefore, the upper surface of the first glass plate 8 is at least partially located in the first storage room 2, forming a support for placing on it, for example, products to be cooled.

The spacer element 4 comprises locking means 32 for preventing the spacer element 4 from moving in the forward direction. In this embodiment, the locking means 32 is made in the form of a protrusion directed from top to bottom from the side of the frame 30. The separation wall 27 and / or the corresponding side wall 26 are provided with a locking groove (not shown), which includes the locking means. If the protrusion is inserted into the locking groove, the horizontal movement of the separating element 4 is limited by the locking groove, so that the separating element 4 can be firmly fixed in the refrigeration apparatus 1 in order to isolate the first storage room 2 from the second storage room 3. In an alternative embodiment, the locking groove may be provided on the separation element 4, and the protrusion on the separation wall 27 and / or on the side wall 26, so that the protrusion can be inserted into the locking groove in order to secure the separation element 4.

The separation element 4 comprises a lower plate 17 located below the hollow glass block 7. The lower plate 17 is located essentially parallel to the second glass plate 9 and is connected to the frame 30 by means of a mounting frame 33, protruding upward from the edge of the lower plate. The lower plate 17 is located at some distance from the second glass plate 19, and a channel 12 is formed through which the air contained in the second storage room 3 can exit from the second storage room 3.

The hollow glass block 7 has a length in the direction from the front to the rear wall less than the depth of the second storage room 3. In this case, the separation element 4 contains an insulating strip 14, which is located between the rear end of the hollow glass block 7 and the rear surface of the second storage room 3. In this embodiment, the insulating strip 14 is made of expanded polystyrene (Expanded Polystyrene Styrofoam, EPS).

Gas in the second storage room 3 enters the channel 12 through a plurality of inlets 13 made in the lower plate 17. The lower plate 17 contains a first region 18 and a second region 19, while the first region 18 is located far from the dividing wall 27 on which an air duct 11 (serving as a cooling source of the second storage room 3), and the second region 19 is located near the partition wall 27. The first region 18 and the second region 19 are separated essentially along the central axis in the direction from the front to the back side of the bottom plate 17. In this embodiment, the inlets 13 are disposed mainly in the first region 18 and second region 19 includes no inlet openings 13, so the cold air from the freezer compartment 22 may be uniformly distributed in the second storage room 3. Each of the inlets 13 has an elongated shape, and the inlets 13 are arranged in two rows in the first region 18.

The outlet 16 of the channel 12 is oriented in the direction of the rear wall of the separation element 4, thus the inlet 13 and the outlet 16 are respectively oriented in planes perpendicular to each other. In this embodiment, the outlet 16 is preferably connected via a suitable pipe (not shown) to a chamber in which an evaporator (not shown) is installed for the freezer compartment 22. The outlet 16 is formed at a position corresponding to the second region 19 of the bottom plate 17, thus you can increase the air duct through which air passes from the inlet 13 to the channel 12.

The separation element 4 preferably comprises a baffle 34 mounted on one side of the outlet 16 in the vicinity of the first region 18. As shown in FIG. 5, the baffle 34 enters the channel 12, thereby preventing air from entering through the inlets 13 located near the outlet 16 , in the outlet 16 in a very short way.

As shown in FIG. 5, the separation element 4 comprises a filter element 20 for adjusting at least one parameter of the storage mode in the second storage room 3. In this embodiment, the filter element 20 comprises a filter cloth for filtering water to maintain humidity in the second storage room 3. In this embodiment, the inlets 13 are covered by a filter element 20.

The separation element 4 comprises a support plate 35 for attaching the filter cloth to the separation element 4. The support plate 35 is attached to the bottom plate 17 and has a shape corresponding to the shape of the first region 18. The support plate 35 comprises a plurality of through holes matching the inlets 13.

In the above embodiment, the hollow glass block 7 contains only two glass plates, however, it should be understood that in an alternative embodiment, the hollow glass block 7 may contain more than two glass plates, in particular three glass plates.
