The present invention relates to refrigeration plant, more particularly to a kind of semiconductor defrosting refrigerator.
Background technology
The refrigerating chamber and refrigerating chamber of conventional domestic refrigerator, refrigerating chamber and refrigerating chamber are cooled respectively using refrigerant shunting, Control section is more complicated, and its defrost uses heating wire defrost, and the high temperature of heating wire and electric leakage must take safeguard measure, and defrost This partial capability slatterns, or uses hot gas defrost, using the hot gas of compressor discharge directly by evaporator defrost, exists Magnetic valve reliability and compressor return air pressure are high, reduce compressor service life, and the problems such as defrost efficiency is low;Present part Two compressors of use of commercial wind cooling refrigerator cool to refrigerating chamber and refrigerating chamber respectively, than the cost with a compressor assembly Much higher, it freezes defrost and also uses heating wire defrost in addition, and shortcoming is also that the high temperature of heating wire and electric leakage must take protection Measure, product reliability is reduced, the energy of defrost is also what is slatterned.
The content of the invention
It is reliable the technical problem to be solved in the present invention is to provide one kind, efficiently, the air-cooled frost-free refrigerator of cost-saving.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is:A kind of semiconductor defrosting refrigerator, including pressure Contracting machine, condenser, evaporator, and the semiconductor chilling plate for defrost;
Compressor is connected with evaporator by condenser and is circulated back to compressor;The heat of evaporator and semiconductor chilling plate End connection;The cold end of semiconductor chilling plate is connected with refrigerating chamber.
Preferably, in addition to semiconductor evaporation fan;Semiconductor evaporation fan is arranged on the cold end of semiconductor chilling plate.
Another is preferably, in addition to metal heat pipe;The hot junction of semiconductor chilling plate is connect by metal heat pipe and evaporator Touch heat exchange and carry out defrost.
It is further preferred that, in addition to condensation fan;Condensation fan is arranged on condenser.
It is further preferred that, evaporator is air-cooled evaporator;Air-cooled evaporator is conveyed cold by evaporation fan To cooling space.
Also one preferably, in addition to refrigerating chamber, refrigerating chamber and cold regulation blower fan;Cold regulation blower fan is from refrigerating chamber Extract cold and be sent to refrigerating chamber.
The beneficial effects of the invention are as follows:
Using semiconductor refrigeration system as defrosting system, its hot junction provides the heat that defrost needs, and its cold end is to refrigeration Room cools;It is reliable with efficient energy-saving, it is cost-effective the advantages of.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is the schematic diagram of semiconductor defrosting refrigerator embodiment of the present invention.
Fig. 2 is the structural representation of semiconductor defrosting refrigerator embodiment of the present invention.
Marked in figure:1- compressors, 2- condensation fans, 3- condensers, 4- evaporators, 5- evaporation fans, 6- metal heat pipes, 7- semiconductor evaporating plates, 8- semiconductor evaporation fans, 9- cold regulation blower fans, 10- refrigerating chambers, 11- refrigerating chambers.
Embodiment
Fig. 1 is a kind of schematic diagram of semiconductor defrosting refrigerator, by compressor 1, evaporator 4, and evaporation fan 5, condenser 3, Condensation fan 2, cold regulation blower fan 9, semiconductor chilling plate, semiconductor evaporating plate 7, semiconductor evaporation fan 8, metal heat pipe 6 Composition.
Semiconductor chilling plate uses the semi-conducting material with Peltier effect to be made.Its hot junction is equipped with metal heat pipe 6, its Cold end is equipped with semiconductor evaporating plate 7 and semiconductor evaporation fan 8.
Compressor 1 is connected with evaporator 4 by condenser 3 and is circulated back to compressor 1, forms a refrigeration system.
In addition, evaporator 4 is connected with the metal heat pipe 6 of semiconductor chilling plate;The semiconductor evaporating plate 7 of semiconductor chilling plate It is connected by semiconductor evaporation fan 8 with refrigerating chamber 10, thus constitutes semiconductor transformation defrosting system.
Evaporator is air-cooled evaporator, and cold is delivered to cooling space by air-cooled evaporator by evaporation fan.
The present embodiment realizes single compression dual temperature room, and compressor 1 only directly provides cold for refrigerating chamber 11, and refrigerating chamber 10 freezes By cold regulation blower fan 9 refrigerating chamber is transferred to from refrigerating chamber 11.
The present embodiment defrosting system is completed by a semiconductor refrigeration system, and semiconductor cold end is placed in refrigerating chamber, to refrigeration Room is freezed, and semiconductor hot junction is by heat pipe and needs the evaporation of defrost to carry out heat exchange, so as to reach defrost effect, and realizes cold The transfer of amount.
Fig. 2 is the specific product structure of the present embodiment, and its course of work is as follows:
Refrigerant compression was entered condenser 3 and cooled down with condensation fan 2 by compressor 1, and evaporator 4, evaporation are flowed into after throttling Device 4 is that refrigerating chamber 11 directly provides cold, and the cold of refrigerating chamber 10 extracts by cold regulation blower fan 9 from refrigerating chamber 11.Working as When white, semiconductor refrigeration system starts, and compressor assembly is out of service, and semiconductor evaporation block 7 and semiconductor evaporation fan 8 are to cold Room refrigeration is hidden, semiconductor hot junction by heat and needs the evaporator of defrost to carry out heat exchange, plays defrost mesh by metal heat pipe 6 , while semiconductor refrigeration system realizes transfer of the cold from evaporator ice cube to refrigerating chamber.
The embodiments of the present invention described above are not intended to limit the scope of the present invention.It is any in the present invention Spirit and principle within the modifications, equivalent substitutions and improvements made etc., should be included in the claim protection model of the present invention Within enclosing.
