Brief description of the drawings
Schematic diagram when Fig. 1 is present invention refrigeration；
Schematic diagram when Fig. 2 is defrost of the present invention.
Specific embodiment
First embodiment, as depicted in figs. 1 and 2, a kind of medical refrigerator-freezer defrosting device, including cabinet 10 and refrigerator 300,
10 points of cabinet is storage area 100 and defrost area 200, the first air-valve 101 between storage area 100 and defrost area 200 by being provided with
Evaporator 204 is installed in connection, defrost area 200, the blower fan 203 for driving gas flowing in defrost area 200, and water receiving
Groove 206；Evaporator 204 and refrigerator 300 pass through the pipeline communication being provided with, and one end of water receiving tank 206 is connected with evaporator 204,
The other end is docked with the outside of cabinet 10.
As shown in figure 1, schematic diagram during for normal refrigeration, arrow represents the flow direction of cold air in figure, and refrigerator 300 is to evaporation
Input cold air in device 204, now, the first air-valve 101 is opened, and storage area 100 is connected with defrost area 200, and cold air is in blower fan
Moved along the direction of the arrow in Figure under 203 blowing, cold air is circulated between storage area 100 and defrost area 200, now cold
Gas is cooled down to the food in storage area 100.
As shown in Fig. 2 schematic diagram during for defrost, arrow represents the flow direction of hot gas in figure, and refrigerator 300 is to evaporator
Input hot gas in 204, now, the first air-valve 101 is closed, and storage area 100 and defrost area 200 separate, and hot gas is in blower fan 203
Blowing under move along the direction of the arrow in Figure, hot gas is in the internal circulation flow of defrost area 200, during defrost, the temperature in defrost area
Rising does not influence temperature change in storage area 100 so that the temperature in storage area 100 is constant in the range of restriction, blower fan 203
Drive hot air circulation to accelerate the defrost time, reduce energy consumption.The ice cube of thawing discharges cabinet 10 through water receiving tank 206.In water receiving tank 206
Heating tube 205 is provided with, the ice cube heating that heating tube 205 pairs flows through water receiving tank 206 has further speeded up dissolving for ice cube.
As shown in Fig. 2 medical refrigerator-freezer defrosting device also includes drainpipe 207 and water leg 209, water leg 209 is fixed and set
In the outer wall of cabinet 10, one end of drainpipe 207 is docked with water receiving tank 206, and the other end is docked with water leg 209.In water leg 209
It is provided with heater strip.Ice cube after defrost flows to water leg 209 through water receiving tank 206, and the heating wire in water leg 209 is in it
Liquid is heated.
As depicted in figs. 1 and 2, be provided with refrigerator pipe 301 and heating pipe 302 in refrigerator 300, heating pipe 302 be provided with for
Open and close the valve 303 of heating pipe 302.When cabinet 10 needs refrigeration, valve 303 is closed, refrigerator 300 is to cabinet 10
Interior refrigeration, when defrost area 200 needs defrost, opens valve 303, and hot gas enters in defrost area 200, now due to hot gas
