Description

Technical Field

[0001] The utility model relates to a wine cabinet, in particular to a direct cooling and dual-temperature wine cabinet, belonging to the technical field of wine cabinets. Background Art

[0002] In the prior art, most dual-temperature refrigerators on the market are air-cooled dual-temperature refrigerators consisting of an upper chamber and a lower chamber. The upper chamber is equipped with a finned evaporator for cooling, and the cold air from the upper chamber is transferred to the lower chamber through a cooling fan and a heat insulation board fan, so that the upper and lower chambers reach the set temperature. However, the cost of cooling with a finned evaporator is relatively high. The direct-cooling inflation evaporator has the advantage of lower cost compared to the finned evaporator. However, because the direct-cooling inflation evaporator is mostly in the shape of a flat plate, the installation space of the upper chamber is limited, and the evaporator is installed too small for sufficient cooling capacity. When the cold air is transferred to the lower chamber, the temperature cannot be lowered. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a direct cooling dual-temperature wine cabinet, which can provide a sufficiently large refrigeration capacity in a small space in the upper chamber, so that the temperatures of the upper chamber and the lower chamber can be lowered as quickly as possible.

[0004] The utility model can adopt the following technical solutions:

[0005] A direct cooling dual-temperature wine cabinet comprises a box body, an inner tank, and a direct cooling inflation type evaporator. The inner tank is located in the box body, and a horizontal partition is provided in the inner tank to divide the inner tank into an upper chamber and a lower chamber; the direct cooling inflation type evaporator comprises a vertical plate and a horizontal plate, and the vertical plate and the horizontal plate are connected together to form an L-shaped direct cooling inflation type evaporator; the direct cooling inflation type evaporator is located in the upper chamber, the vertical plate is located on the inner wall of the inner tank, and the horizontal plate is located on the partition; a cooling fan is provided on the direct cooling inflation type evaporator; the partition is a thermal insulation plate, and an air inlet is provided on one side wall of the thermal insulation plate close to the inner tank, and a return air outlet is provided on the other side wall of the thermal insulation plate close to the inner tank; a thermal insulation plate fan is provided in the inner tank to make the air in the upper chamber enter the lower chamber through the air inlet, and then return to the upper chamber through the return air outlet for continuous circulation.

[0006] The utility model can further solve the problem by taking the following improvement measures:

[0007] Further improvements are as follows: the insulation board is inclined, the position of the insulation board at the inner tank opening is the front end of the insulation board, the position of the insulation board at the rear inner wall of the inner tank is the rear end of the insulation board, the rear end of the insulation board is lower than the front end of the insulation board; there is a gap between the rear end of the insulation board and the horizontal plate.

[0008] A further improvement is that the cooling fan is installed on the direct-cooling inflation evaporator through a cooling fan bracket.

[0009] A further improvement is that the cooling fan bracket is installed on the vertical plate.

[0010] A further improvement is that: the vertical plate is provided with a mounting hole, and the cooling fan bracket is connected to the vertical plate through the mounting hole.

[0011] A further improvement is that a temperature-insulating cavity is provided under the temperature-insulating plate, the temperature-insulating cavity is connected with the air inlet, and the temperature-insulating cavity is provided with an air outlet connected with the lower chamber.

[0012] A further improvement is that the temperature-insulating cavity is surrounded by a temperature-insulating plate, a lower plate, and air duct foam; the lower plate is L-shaped, and the air outlet is arranged on the lower plate.

[0013] A further improvement is that the insulation board fan is arranged in the insulation cavity.

[0014] A further improvement is that the insulation board fan is arranged at the air outlet.

[0015] The above technical solution has the following technical effects:

[0016] 1. The direct cooling and blowing evaporator of the utility model is L-shaped, which can expand the area of ​​the direct cooling and blowing evaporator under the limited space of the upper chamber, ensuring that the evaporator is large enough to provide cooling capacity, so that the temperature of the upper chamber and the lower chamber can be reduced to the set requirements. The temperature of the upper chamber and the lower chamber can be reduced as soon as possible.

[0017] 2. The rear end of the insulation board of the utility model is lower than the front end of the insulation board. In this way, the insulation board can receive the condensed water of the inflation evaporator, and the condensed water of the evaporator can be directed to the wall of the inner tank through the insulation board, and then flow into the water tank of the inner tank. This can prevent the condensed water of the evaporator from scattering.

[0018] 3. The utility model has a simple and compact structure. BRIEF DESCRIPTION OF THE DRAWINGS

The direct cooling inflation type evaporator 3 is located in the upper chamber, and the vertical plate is located on the inner wall of the inner liner. In this example, the vertical plate is located on the back wall of the inner wall of the inner liner. The horizontal plate is located on the partition.

The partition is a thermal insulation plate 5, and the thermal insulation plate 5 is provided with an air inlet 6 on one side wall close to the inner liner, and the thermal insulation plate is provided with a return air port 7 on the other side wall close to the inner liner. The inner tank is provided with a heat-insulating plate fan 8 to allow the air in the upper chamber to enter the lower chamber through the air inlet, and then return to the upper chamber through the return air outlet for continuous circulation, that is, when the heat-insulating plate fan is working, the cold air in the upper chamber can enter the lower chamber through the air inlet, and then return to the upper chamber through the return air outlet, and so on for continuous circulation. The rest can be the same as the conventional wine cabinet.

[0028] Working principle: The direct cooling expansion evaporator includes a vertical plate and a horizontal plate, which are connected together to form an L-shaped direct cooling expansion evaporator. The direct cooling expansion evaporator of the utility model is L-shaped, which can expand the area of ​​the direct cooling expansion evaporator under the limited space of the upper chamber, ensuring that the evaporator is large enough to provide cooling capacity, so that the temperature of the upper chamber and the lower chamber can be reduced to the set requirements.

There is a gap between the rear end of the insulation board and the horizontal plate. In this way, the insulation board can have the function of receiving the condensed water of the inflation evaporator, and the condensed water of the evaporator can be guided to the inner tank wall through the insulation board, and then flow into the inner tank water tank 21. The rest is the same as Example 1.

The lower plate is L-shaped, and the air outlet 10 is provided at the lower plate 51. This structure uses the temperature-insulating plate and the lower plate foam to form the temperature-insulating cavity, which can effectively isolate the temperature of the upper chamber and the lower chamber. The temperature difference between the upper chamber and the lower chamber can be generated as needed. The structure is simple and compact.

[0033] The rest may be the same as in Example 3.
