The invention discloses a warm air type temperature-equalizing wine cabinet, which comprises a cabinet body 200 and an air duct arranged in the cabinet body 200, wherein a plurality of first storage areas 110, second storage areas 120 and third storage areas 130 for placing red wine are vertically arranged in the cabinet body 200 along the height direction of the cabinet body, an evaporation fan 800 and an evaporator 700 are arranged in the air duct, the left side and the right side of the upper part of the air duct are provided with a first air supply opening 511 for supplying air to each layer of the first storage area 110 left and right, a second air supply opening 611 for supplying air to the second storage area 120 and a third air supply opening 612 for supplying air to the third storage area 130, and the air duct is also provided with a first air return opening 613 and a second air return opening 621 for returning air to the first storage area 110, the second storage area 120 and the third storage area 130.

Specifically, for the first air supply opening 511, the air duct supplies cool air to the back of each layer of the first storage area 110 in the horizontal direction from the left side to the right side through the first air supply opening 511, the cool air flows to the front through the left side and the right side of the first storage area 110, and the cool air sinks, and since the first air return opening 613 and the second air return opening 621 are located below the first air supply opening 511, the cool air enters the first air return opening 613 and the second air return opening 621 under the suction force of the first air return opening 613 and the second air return opening 621, so as to form a circulation loop of the air flow. Compared with the traditional wine cabinet air conditioning, the air conditioning is directly blown to the front part from the rear part of the wine cabinet, the horizontal air supply modes on the left side and the right side avoid the air conditioning to directly blow wine bottles, the local temperature fluctuation of the wine bottles is reduced, the internal temperature equalization of the wine cabinet is realized, the storage environment of red wine is improved, and the use experience of a user is improved.

As for the second blowing port 611, the duct supplies cool air to the second storage area 120 through the second blowing port 611, the cool air sinks through the front of the second storage area 120, and enters the first return air port 613 and the second return air port 621 by the suction force of the first return air port 613 and the second return air port 621, forming a circulation loop of the air flow. Similarly, regarding the third blowing port 612, the duct supplies cool air to the third storage area 130 through the third blowing port 612, and the cool air sinks through the front portion of the third storage area 130 and enters the first return air port 613 and the second return air port 621 by the suction force of the first return air port 613 and the second return air port 621, thereby forming a circulation loop of the air flow.

When the compressor is in a shutdown state, the temperature in the wine cabinet reaches the set value of the system at the moment, and the heating wires 900 operate at a low operation rate, so that the air blown out from the air supply outlet is ensured to be greater than 0 ℃, and the air outlet effect of warm air is realized.

For the specific bonding position of the heating wire in the air duct, the heating wire is bonded on the first vertical part of the upper air duct cover plate in the embodiment. Because first vertical portion is equipped with a plurality of first supply-air outlets of controlling the air-out along its axis direction, locate the heater strip on first vertical portion, can make the warm braw after the heating blow off from a plurality of first supply-air outlets and fourth supply-air outlet simultaneously, improve out the warm braw effect.
