The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The refrigerator in the application is an air-cooled refrigerator, and a refrigerating system comprises a compressor, a condenser, an evaporator, a throttling device and the like.

The refrigerator in this application has fresh-keeping drawer 500, and fan 600 blows the cold air that refrigerating system produced to in the fresh-keeping drawer 500 to keep the low temperature in the fresh-keeping drawer 500.

Referring to fig. 1 to 3, the refrigerator includes an inner container 100, the inner container 100 encloses a refrigerating chamber 110, and an air duct 210 is disposed in a foaming layer of the inner container 100.

One of the purposes of the application is to reduce the cold loss of cold air when flowing through the air duct 210, improve the heat preservation effect of the air duct 210, improve the temperature accuracy in the fresh-keeping drawer 500, and improve the fresh-keeping effect of food materials.

In order to achieve the above purpose, in some embodiments of the present application, a mounting cavity 400 is provided in the refrigerating chamber 110, and the mounting cavity 400 is defined by a plastic plate. The installation cavity 400 is open at the front side.

Be equipped with fresh-keeping drawer 500 in installation cavity 400, fresh-keeping drawer 500 passes through slide isotructure and can pull for installation cavity 400 front and back to realize opening and closing of fresh-keeping drawer 500.

The air duct 210 is disposed in the foaming layer of the inner container 100 located at the rear side, an air inlet 410 is disposed on the rear side plate enclosing the installation cavity 400, and an air outlet 211 of the air duct is communicated with the air inlet 410, so that the fan 600 blows cold air into the installation cavity 400 through the air duct 210, the air outlet 211 of the air duct and the air inlet 410 in sequence, thereby realizing the low temperature of the preservation drawer 500.

Be equipped with insulation material on the lateral wall that encloses into wind channel 210, insulation material can effectively avoid air conditioning to produce cold volume loss when wind channel 210 flows through, improves wind channel 210 heat preservation effect, improves the accurate nature of the temperature in the fresh-keeping drawer 500, improves and eats the material fresh-keeping effect.

Since the preservation low temperature required for different food materials is different, it is necessary that the preservation drawer 500 can provide different low temperature environments for different food materials. In some embodiments of the application, different temperatures in the fresh-keeping drawer can be realized by means of reducing the rotating speed of the fan, reducing the operating power of the evaporator, controlling the air distribution and the like.

In some embodiments of the present application, the insulation material includes insulation foam 310 and/or vacuum insulation 320. The vacuum heat insulation member 320 has better heat insulation effect, further improves the heat insulation effect of the air duct 210, and reduces the loss of cold energy.

As a specific embodiment, in view of the fact that the vacuum insulation member has higher cost than the thermal insulation foam, the thermal insulation material adopts a combination structure of the thermal insulation foam 310 and the vacuum insulation member 320, so that the product cost can be limited within a certain range while the thermal insulation effect of the air duct 210 is improved.

Referring to fig. 2 and 3, a foam member 200 is provided in the foaming layer, and an air duct 210 is formed in the foam member 200. In actual production, the air duct 210 may be dug directly on the foam member 200, and one side of the air duct 210 is opened.

The insulating foam 310 is adhered and fixed on the inner side wall of the air duct 210, and the vacuum heat insulation member 320 is adhered and fixed on the open side of the air duct 210, so that the outer periphery of the air duct 210 is coated to the maximum extent, and the heat insulation effect of the air duct 210 is improved.

The vacuum heat insulation piece 320 plays a role in plugging a single-side air duct while playing a role in heat insulation and preservation, and improves the sealing effect of the air duct.

In some embodiments of the present disclosure, the air duct 210 is provided with a damper 212, and the damper 212 is used for controlling the air circulation in the air duct 210.

After the refrigerator works for a period of time, the evaporator frosts, and when the frosting amount reaches a certain value, the refrigerator enters a defrosting working mode to defrost the evaporator so as to improve the refrigerating effect and efficiency.

The evaporator is provided with a heating wire, the heating wire is electrified for heating, and the temperature near the evaporator is increased, so that defrosting of the evaporator is realized.

When defrosting, the air door 212 is closed to prevent hot air from entering the preservation drawer 500 through the air duct 210 to affect the low temperature in the preservation drawer 500 and the preservation effect.

After the refrigerator is switched from the defrosting operation mode to the refrigerating operation mode, the air door 212 is opened again after the refrigerator operates in the refrigerating operation mode for a period of time. This is because, after defrosting is finished, some hot air still exists in the air duct of the cold air circulation, after the cooling operation is performed for a period of time, the hot air still existing can be eliminated, and at this time, the air door 212 is opened, so that the low-temperature cold air entering the fresh-keeping drawer 500 can be ensured.

In some embodiments of the present application, the outside of the rear side plate enclosing the installation cavity 400 is provided with a sponge 420, the sponge 420 encloses the periphery of the air inlet 410, and the sponge 420 is abutted and sealed with the inner container 100 to ensure the sealing of the butt joint of the air inlet 410 and the air outlet 211 of the air duct.

In some embodiments of the present application, referring to fig. 4, a temperature sensor 700 is disposed at the air outlet 211 near the air duct in the air duct 210 to ensure that the temperature of the cool air entering the fresh-keeping drawer 500 can reach a set temperature range, so as to avoid over-low freezing injury of food materials or over-high temperature reduction of the fresh-keeping effect.

In some embodiments of the present application, a plurality of grilles 411 are spaced at the air inlet 410 to flow the cold air flowing through the air inlet 410 uniformly.

In some embodiments of the present application, the crisper drawer 500 has a plurality of crisper drawers, and the air duct 210 also has a plurality of crisper drawers 500, which are correspondingly communicated with the air ducts 210. Fig. 1 to 3 illustrate the crisper drawer 500 and the air duct 210 as two examples.

The independent air ducts 210 facilitate independent temperature control of the fresh-keeping drawers 500 to meet the fresh-keeping temperature requirements of different food materials.

A fan installation cavity 220 is arranged in a foaming layer of the inner container 100 positioned at the rear side, and the air channels 210 are all communicated with the fan installation cavity 220.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
