As shown in fig. 1 to 3, a cold and hot double temperature display cabinet according to a preferred embodiment of the present invention mainly includes a cabinet 100, a compressor 200, a first condenser 300, a first fan 310, a second condenser 400, a second fan 410, a throttle controller 500, a drying filter, a capillary tube, an evaporator 800, and an evaporation fan 810.

The cabinet 100 defines at least one cooling compartment 110 and at least one heating compartment 120 therein, and defines a cool air duct 130 communicating with the cooling compartment 110 and a warm air duct 140 communicating with the heating compartment 120.

The compressor 200, the second condenser 400 and the second fan 410 are all disposed in the cabinet 100.

Referring to fig. 1 to 4, the discharge end of the compressor 200 is sequentially communicated with the throttle controller 500 and the first condenser 300 through the first branch pipe 210, and is sequentially communicated with the second condenser 400, the dry filter, the capillary tube, the evaporator 800 and the air return end of the compressor 200 through the second branch pipe 220, and the output pipe of the first condenser 300 is connected to the output pipe of the second condenser 400 (it can be understood that the output pipe of the first condenser 300 is connected to the pipe section between the second condenser 400 and the dry filter). The first condenser 300 and the first fan 310 are disposed in the hot air duct 140, the evaporator 800 and the evaporation fan 810 are disposed in the cold air duct 130, and the second condenser 400 and the second fan 410 are disposed in the cabinet 100.

Referring to fig. 4, an arrow in fig. 4 indicates a flowing direction of a refrigerant, when the cooling and heating dual temperature display cabinet needs to be heated, a portion of the refrigerant discharged from a discharge end of the compressor 200 enters the throttle controller 500 along the first branch pipe 210, and an amount of the refrigerant entering the first condenser 300 is controlled by the throttle controller 500 according to a heating temperature and speed requirement of the heating chamber 120. The refrigerant is condensed by the first condenser 300, in the process, the first condenser 300 emits heat to heat the air in the hot air duct 140, and the first fan 310 blows hot air into the heating chamber 120, so as to achieve the effect of heating the inside of the heating chamber 120. The heating process does not affect the operation of the refrigeration cycle, that is, other refrigerants discharged from the discharge end of the compressor 200 directly enter the second condenser 400 along the second branch pipe 220, and the refrigerants passing through the first condenser 300 flow back to the output end of the second condenser 400, and continue to participate in the subsequent refrigeration process with other refrigerants passing through the second condenser 400, that is, continue to flow into the dry filter (not shown), the capillary tube (not shown), the evaporator 800 and the air return end of the compressor 200 in sequence, thereby completing the refrigeration cycle process. During refrigeration, the refrigerant is condensed by the second condenser 400, heat emitted by the second condenser 400 is blown away by the second fan 410, when the refrigerant is evaporated by the evaporator 800, the evaporator 800 absorbs heat to cool air in the cold air duct 130, and the evaporation fan 810 blows cold air into the refrigeration chamber 110, so that the effect of cooling the interior of the refrigeration chamber 110 is achieved.

Referring to fig. 1-3, the cabinet 100 includes an outer shell 150, an upper liner 160, and a lower liner 170. The upper and lower

inner containers

In practice, a partition plate can be used to separate a liner into an upper liner 160 and a lower liner 170 that are not connected to each other. An inverted L-shaped upper air duct plate 180 is disposed in the upper inner container 160 to divide the space of the upper inner container 160 into a hot air duct 140 located at the rear top and a heating chamber 120 located at the front lower portion, and the first condenser 300 and the first fan 310 are disposed at the top of the hot air duct 140. An upper air inlet hole (not shown) is formed in the upper top plate 182 of the upper air duct plate 180, and an upper air return hole (not shown) is formed in the upper back plate 181 of the upper air duct plate 180 at a position corresponding to a position between every two shelves, so that hot air in the hot air duct 140 enters the heating chamber 120 from the top and returns to the hot air duct 140 from the upper air return hole, and hot air circulation is completed. The lower inner container 170 is internally provided with a lower air duct plate 190 which divides the space of the lower inner container 170 into a cold air duct 130 at the rear part and a refrigeration chamber 110 at the front part, the evaporator 800 is arranged at the bottom of the cold air duct 130, and the evaporation fan 810 is arranged at the upper part of the cold air duct 130. A lower air inlet hole (not shown) is formed in the position, corresponding to the evaporation fan 810, of the lower back plate 191 of the lower air duct plate 190, and a lower air return hole (not shown) is formed in the bottom of the lower back plate 191, so that cold air in the cold air duct 130 enters the refrigeration cavity 110 from the upper portion and returns to the cold air duct 130 from the lower air return hole, and cold air circulation is completed.

In some embodiments, referring to fig. 2, a control unit 900 is disposed at the front top plate 183 of the upper duct plate 180, and is electrically connected to the throttle controller 500 for controlling the operation of the throttle controller 500. The throttle controller 500 may be an electrically controlled throttle valve. The control unit 900 may also be electrically connected to the first fan 310 to control the first fan 310 to operate.
