Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
Embodiment one：
As shown in Figs. 1-3, a kind of Internet of Things refrigerator with defrosting function, including form the shell 1 of electromechanical cavity 2, the machine
Compressor 21, condenser 22, evaporator 23 and capillary 24 are equipped in electric cavity 2, the shell 1 is interior equipped with freezing chamber 3 and cold
Room 4 is hidden, the compressor outlet is connect with condenser inlet, evaporator inlet respectively, and the outlet of the condenser is through capillary
Connect with the entrance of evaporator, the entrance of the outlet connect compressor of evaporator, the compressor outlet and condenser inlet it
Between be equipped with the first control valve 5, between compressor outlet and condensator outlet be equipped with the second control valve 6, master control borad 26 is according to long-range
The control signal control refrigerator of control centre switches in defrosting mode and refrigeration mode.
Under refrigeration mode, the first control valve 5 is opened the second control valve 6 and is closed, the high temperature and high pressure gas that compressor 21 comes out
It liquefies after condensed device 22, evaporator 23 is then entered after capillary 24 and device for drying and filtering 25, pressure is returned after gasification heat absorption
Contracting machine 21.
Under defrosting mode, the first control valve close the second control valve open, compressor 21 come out high temperature and high pressure gas into
Enter evaporator, the gas of higher temperature returns to compressor after evaporator is radiated.Due to the defrost since internal, work as defrosting
When completion, outside temperature just starts to increase, therefore can effectively prevent food temperature is higher to lead to bacteria breed.
Due to the common components that defrost and freeze, heater need not be additionally set, space is effectively saved, reduced
Cost.
The first temperature sensor 41 is equipped in refrigerator cold-storage room, the entrance of the evaporator is equipped with second temperature sensor
71, the outlet of evaporator is equipped with third temperature sensor 72.
Master control borad determines frosting coefficient according to the temperature information of sensor detection
The temperature difference of gas calculates frosting COEFFICIENT K in temperature and evaporator due to considering refrigerating chamber, to make
The critical point that must be defrosted is accurately calculated, and can both have been prevented energy loss caused by defrosting too early, also effectively prevent defrosting too late
When caused by refrigerating efficiency it is low.
A kind of working method of the Internet of Things refrigerator with defrosting function, includes the following steps：
A. the first control valve is opened the second control valve and is closed, and refrigerator works in cooling mode；
