Abstract
An automatic defrosting device for an air conditioner comprises a radiator, an evaporator, a compressor and a discharge pipe on the compressor, wherein the radiator and the evaporator are arranged in a machine body side by side; the compressor is also arranged in the machine body; the discharge pipe is communicated with a capillary tube on both the radiator and the evaporator. The automatic defrosting device further comprises an electromagnetic defrosting valve and a temperature sensor which are connected with each other, wherein the electromagnetic defrosting valve is arranged beside the compressor, and is connected with the evaporator; the temperature sensor is arranged on the evaporator. The automatic defrosting device utilizes the electromagnetic defrosting valve and the temperature sensor to realize automatic defrosting, is simple in structure and good in defrosting effect, and ensures that the compressor does not need to stop in the defrosting process, thereby reducing impact caused by start and stop and prolonging the service life accordingly.
Description
Technical field
The utility model relates to a kind of automatic defrosting device of air conditioner, belongs to the improvement of air conditioner frost-removal structure.
Background technology
The easily frosting under low temperature situation of general air conditioner, the defrost of existing air conditioner is by stopping compressor operation, and by the temperature of natural environment and the effect of fan, thereby the frostization on evaporimeter is clean.But if the temperature of natural environment is too low, extremely difficult that frostization on evaporimeter is clean, thus cannot normally bring into play refrigerating function; And compressor start-stop is frequent, affect the service life of compressor.
Utility model content
The deficiency existing for above-mentioned prior art, the purpose of this utility model be to provide a kind of simple in structure, cost is low, defrost is effective and the automatic defrosting device of the air conditioner of compressor long service life.
Technical approach of the present utility model is to provide a kind of automatic defrosting device of air conditioner, it comprises the discharge pipe on radiator, evaporimeter, compressor, compressor, described radiator and evaporimeter are set up in parallel in body, compressor is arranged in body, discharge pipe is connected with the capillary being arranged on radiator and evaporimeter, it is characterized in that: also comprise electromagnetism defrost valve and temperature inductor, described electromagnetism defrost valve is connected with temperature inductor, electromagnetism defrost valve is arranged on compressor side and is connected with evaporimeter, and described temperature inductor is arranged on evaporimeter.
The utility model has the advantages that: the utility model utilizes magnetic valve and temperature inductor to reach automatic defrosting, and it is simple in structure, defrost is effective, another defrost process does not need to stop compressor, has reduced the impact that start-stop brings and the life-span is extended.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model fundamental diagram.
The specific embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As shown in Figure 1, the automatic defrosting device of air conditioner comprises the discharge pipe 4 on radiator 1, evaporimeter 2, compressor 3, compressor, radiator 1 is set up in parallel in body with evaporimeter 2, compressor 3 is arranged in body, discharge pipe 4 is connected with the capillary 6 being arranged on radiator 1 and evaporimeter 2 by threeway 5, also comprise electromagnetism defrost valve 7 and temperature inductor 8, electromagnetism defrost valve 7 is connected with temperature inductor 8, electromagnetism defrost valve 7 is arranged on compressor 3 sides and is connected with evaporimeter 2, and temperature inductor 8 is arranged on evaporimeter 2.
As shown in Figure 2, the utility model does not need by fan 9, frostization is clean merely, but realizes automatic defrosting by the effect of temperature inductor 8 and electromagnetism defrost valve 7.When machine works, electromagnetism defrost valve 7 does not operate and does not start; Only have when temperature inductor 8 temperature sensors are during lower than zero degree, start immediately electromagnetism defrost valve 7, now electromagnetism defrost valve 7 branches to capillary 6 by the thermal source of discharge pipe 4, and to evaporimeter 2, plays defrost through electromagnetism defrost valve 7; And after defrost, inductor 8 temperature sensors are during higher than zero degree, electromagnetism defrost valve 7 cuts out shunting immediately, and electromagnetism defrost valve 7 decommissions.So circulation running.
