Specifically, the present invention provides a kind of showcases with cold-hot heat preservation function.When work, showcase connects
Energization source selects the compressor 7 and evaporator to freeze according to demand, or selection PTC heaters 3 are heated.Work as exhibition
When showing that cabinet needs low temperature to show, refrigeration is selected at operation, condenser 9, compressor 7 and the evaporator work being mounted on pedestal 8
Make, generate cold air, the cold air below showcase continues to increase and by pipeline to transmitting inside showcase, is carried out to showcase
Cooling.Second motor 5 rotation simultaneously drives the second fan blade 6 to be rotated with third fan blade 61, and the cold air that can generate evaporator is upward
In uniform transmission to showcase cavity, while the heat that the work of condenser 9 generates is transported to showcase glass by ventilation opening 16
Glass lateral surface, and the after-heat of heat and condenser periphery that compressor generates is discharged by left and right thermovent.Showcase
Inside have temperature sensor, refrigeration can be automatically stopped after preset temperature is reached inside showcase, higher than weight after preset temperature
It is new to start.
When showcase needs high temperature to show, selects heating, PTC heaters 3 to start to work at operation, it is empty to generate heat
Gas；First motor 1 works simultaneously, drives the rotation of the first fan blade 2, the hot-air that PTC heaters 3 generate is made to be transported in showcase
Portion can be automatically stopped heating after reaching preset temperature inside showcase, less than being restarted after preset temperature.
When dark, can be improved at operation by switching the transparent lamp plate opened and be mounted below top plate 10
Showcase internal brightness.
