Detailed ways

Figure 1 is a schematic structural diagram of an inner pot 200 for a refrigerator 10 according to an embodiment of the present invention. Figure 1 (a) and (b) respectively illustrate the structure of the inner bladder 200 from two different perspectives. The inner pot 200 of this embodiment is used to be assembled to the box shell of the refrigerator 10 to form the box body 110 .

The inner bladder 200 has a first cooling area 210 and a second cooling area 220. The first cooling area 210 and the second cooling area 220 are respectively used to install evaporators. That is to say, each cooling zone forms an evaporator installation area. The inner bladder 200 of this embodiment can be equipped with two evaporators at the same time to form a double evaporator inner bladder 200 .

The first cooling area 210 and the second cooling area 220 may be simultaneously arranged on any wall of the inner tank 200, such as the rear wall, top wall, bottom wall or side wall. Of course, according to the layout requirements, the first The first cooling area 210 and the second cooling area 220 can also be respectively arranged on any different walls of the inner tank 200.

This embodiment provides a dual evaporator liner 200 by reasonably zoning the liner 200 . Since the liner 200 defines the first cooling area 210 and the second cooling area 220 at the same time, and each cooling area is used to install an evaporator, the space utilization of the liner 200 is improved, and different evaporators can be installed at the same time. Assembled into the same inner container 200 , this is beneficial to improving the integration of the refrigerator 10 .

The type of the inner pot 200 can be selected according to the actual assembly requirements of the refrigerator 10 , for example, it can be a refrigerated inner pot, a freezing inner pot 200 , or a temperature-changing inner pot 200 . In some preferred embodiments, the inner container 200 is a refrigerated inner container. The refrigeration liner is used to assemble the refrigeration evaporator and form the refrigeration compartment.

For most refrigerators 10, such as T-shaped refrigerators 10, the capacity of the refrigeration tank is relatively large. Due to the large volume of the refrigerated liner, when the refrigerated liner is selected as the double evaporator liner 200, the space advantage of the refrigerated liner can be fully utilized to meet the space assembly requirements of the two cooling areas. The cooling of the refrigerator 10 The structural layout has also been adjusted, which is beneficial to improving the refrigeration performance of the refrigerator 10 and allowing the other inner bladders 200 of the refrigerator 10 to release more storage space.

Using the above solution, when cooling capacity needs to be provided to different spaces, the refrigerator 10 can allow a larger number of evaporators to be arranged, thereby improving the temperature control effect of each space and preventing odor transfer.

It should be emphasized that, in view of the layout problem of the evaporator, the layout method adopted in the existing technology is to install the refrigeration evaporator in the center of the rear wall of the refrigeration liner, which will result in the rear wall space of the refrigeration liner not being fully utilized. At the same time, This limits the number of evaporators installed in the refrigerator 10, and may cause the space of other inner pots 200 to be crowded, making it impossible to effectively release storage space. The inventor of the present application creatively set up the first cooling area 210 and the second cooling area 220 on the refrigeration liner of the refrigerator 10 , which breaks through the ideological shackles of the existing technology and provides a reasonable layout for the evaporators of the multi-system refrigerator 10 It provides new ideas and also solves many technical problems such as the complex structure of the cold circuit, achieving multiple goals with one stone.

The refrigeration evaporator used to supply cooling to the refrigerated compartment can be installed in any one of the first cooling area 210 and the second cooling area 220, and the other cooling area can be used to install other evaporators. And use the evaporator to provide cooling to the space outside the refrigerated room. Of course, in the refrigerator 10, the inner tank 200 that can be equipped with two evaporators at the same time is not limited to the refrigeration inner tank.

In some optional embodiments, a refrigeration cooling area for installing a refrigeration evaporator is formed in the first cooling area 210 . The second cooling area 220 forms an ice-making cooling area for installing an ice-making evaporator, or a variable-temperature cooling area for installing a variable-temperature evaporator.

When the refrigerator 10 in the prior art is equipped with a door ice-making module, there is no separate refrigeration system on the door body 120, and the refrigeration system of the freezing compartment needs to be used to provide cooling to the door ice-making module. The system is far away from the door ice-making module. Therefore, a complex cold circuit supply structure needs to be arranged between the two. Not only is the manufacturing cost high, but the cooling efficiency is low and it is easy to carry odor.

When a refrigeration cooling area for installing a refrigeration evaporator is formed in the first cooling area 210, and an ice making cooling area for installing an ice making evaporator is formed in the second cooling area 220, the second cooling area The distance between 220 and the door ice system module is short, and there is no need to arrange a long cooling pipeline between the two. Therefore, it is conducive to simplifying the cold circuit supply structure of the door ice system module, improving refrigeration efficiency, and reducing or avoiding odor transfer. , to achieve “clean ice”.

When the first cooling area 210 is formed with a refrigeration cooling area for installing a refrigeration evaporator, and the second cooling area 220 is formed with a variable temperature cooling area for installing a variable temperature evaporator, the refrigerator 10 may be a variable temperature compartment. Equipped with a separate variable temperature evaporator, which is beneficial to improving the temperature control effect of the variable temperature room.

Of course, in some embodiments, the second cooling area 220 may also form a refrigeration cooling area for installing a refrigeration evaporator. At this time, the freezing evaporator does not need to be installed in the freezing liner 200, thereby fully releasing the storage space in the freezing compartment.

In some optional embodiments, the first cooling area 210 and the second cooling area 220 are thermally isolated from each other and are arranged side by side at the rear wall of the inner bladder 200 in the transverse direction. For example, heat insulation materials can be used for thermal isolation between the first cooling area 210 and the second cooling area 220 to avoid heat exchange and chaos in the cooling process.

Arranging the first cooling area 210 and the second cooling area 220 side by side in the transverse direction can leave the upper spaces of the two cooling areas vacant, so that respective air supply mechanisms can be arranged in the vacant space. or other components to further improve space utilization.

Among them, terms indicating orientation such as "horizontal", "vertical", "front", "rear", "inner", "outer", "upper", "lower", etc. are all relative to the actual use state of the inner bladder 200. The actual use state of the inner bladder 200 refers to the state when the inner bladder 200 is assembled to the box shell and forms the box body 110 .

Of course, the first cooling area 210 and the second cooling area 220 can also be transformed to be arranged side by side along the longitudinal direction, but are not limited thereto.

In some optional embodiments, the inner side of the rear wall of the inner bladder 200 has a forward annular bulge 240, thereby forming a second cooling area 220 therein. The front convex annular bulge 240 extends from a specific annular area on the rear wall of the liner 200 toward the inner side of the liner 200, so that the second cooling area 220 is defined within the front convex annular bulge 240. , and is isolated from the second cooling area 220 located outside the front convex annular bulge 240.

The front convex annular bulge 240 is made of thermal insulation material, and the first cooling zone 210 is disposed on one side of the front convex annular bulge 240 , which allows the front convex annular bulge 240 to perform physical operations on the second cooling zone 220 On the basis of isolation, thermal isolation between the second cooling area 220 and the first cooling area 210 is achieved. For example, the convex annular bulge 240 may be disposed on one side (eg, the left side) of the rear wall of the inner liner 200, and the first cooling area 210 may be disposed on the other lateral side (eg, the right side) of the rear wall of the inner liner 200. , so that the first cooling area 210 and the second cooling area 220 are arranged side by side in the transverse direction.

The front convex annular bulge 240 is integrally formed with the rear wall of the liner 200, so that the front convex annular bulge 240 and the rear wall of the liner 200 are seamlessly connected, which is beneficial to improving the heat insulation of the second cooling area 220. Effect.

In some optional embodiments, the upper section of the first cooling area 210 and the upper section of the second cooling area 220 are also respectively formed with air flow actuating areas 201 for installing fans. That is, each cooling zone also provides space for installing fans. The upper section may refer to the upper space of each cooling zone.

The first cooling zone 210 is configured so that the evaporator is installed below its upper section, and the second cooling zone 220 is configured so that the evaporator is installed below its upper section. That is, the lower section of the cooling area located below the upper section is used to install the evaporator, and each air flow actuating area 201 is located above the evaporator installation area of the cooling area where the evaporator is installed.

When the fan is installed in the upper section of the cooling area, under the actuating action of the fan, each cooling area can circulate air with the corresponding low-temperature storage area, so that the low-temperature storage area can receive the corresponding cooling area. of cooling capacity to achieve temperature control.

In some embodiments, the first cooling area 210 may be offset on one side of the rear wall of the liner 200, and the second cooling area 220 may be offset on the other side of the rear wall of the liner 200. Among them, "offset" means that the first cooling area 210 is set away from the center of the rear wall of the liner 200. It can be offset relative to the lateral direction of the liner 200, or it can be offset relative to the longitudinal direction of the liner 200. .

It should be emphasized that the evaporator is usually disposed in the center of the rear wall of the liner 200 of the prior art, which results in the back wall space of the liner 200 not being fully utilized and also limits the number of evaporators installed in the refrigerator 10 . The inventor of the present application creatively provided an offset first cooling area 210 on the inner container 200 of the refrigerator 10, which can play an avoidance role and provide sufficient installation space around the first cooling area 210. Arranging the second cooling area 220 or installing other components breaks through the ideological shackles of the existing technology and provides new ideas for the refrigerator 10 to rationally utilize space within the limited volume.

In some optional embodiments, the first cooling area 210 is laterally offset to one side of the vertical centerline of the rear wall of the inner bladder 200 . With this arrangement, the space on the lateral side of the first cooling area 210 can be avoided. When the second cooling area 220 is assembled in this avoidance space, the upper space of the first cooling area 210 can be left vacant, thus Air supply mechanisms or other components can be arranged in the vacant space to further improve space utilization.

Figure 2 is a schematic structural diagram of the refrigerator 10 according to one embodiment of the present invention.

In some optional embodiments, the refrigerator 10 has a first inner container 200 formed inside the inner container 200 . A low temperature storage area 230 and a second low temperature storage area 310 located outside the inner tank 200 . For example, when the first cooling area 210 and the second cooling area 220 are formed at the rear wall of the inner tank 200, the first low temperature storage area 230 may be located in front of the first cooling area 210 and the second cooling area 220. Side storage room. The second low-temperature storage area 310 may refer to a storage space defined by other inner pots, or may refer to other low-temperature spaces formed in the refrigerator 10 , such as an ice-making area.

When the inner pot 200 is a refrigerated inner pot, correspondingly, the first low-temperature storage area 230 may be a refrigerated compartment. Preferably, the second low temperature storage area 310 can be a low temperature space provided adjacent to the second cooling area 220 , which can simplify the cold path supply structure between the second cooling area 220 and the second low temperature storage area 310 .

Using the above structure, the refrigeration liner of the refrigerator 10 can be equipped with an additional dedicated evaporator, so that the refrigeration performance of the refrigerator 10 is improved and the space utilization of the refrigeration liner is also improved.
