Specific implementation mode

In conjunction with referring to shown in Fig. 1, Fig. 2, according to an embodiment of the invention, a kind of dehumidifier, including casing 100, institute are provided It states and is equipped with compressor 1, condenser 2, throttle part 3, evaporator 4, the compressor 1, condenser 2, throttle part in casing 100 3, piping connection forms refrigerant circulation circuit to evaporator 4 successively, further includes compressor cooling line, the compressor cooling line In refrigerant come from the condenser 2 and reflux is in the condenser 2, with the cooling compressor 1.It will in the technical solution Refrigerant in the condenser 2 is drained to the compressor 1 by the compressor cooling line, to the compressor 1 It is cooled down, is compared with the prior art, due to being cooled down to the compressor 1 by the compressor cooling line, this energy The components such as enough driving motors efficiently cooled down inside compressor especially compressor, to promoted dehumidifier system efficiency and Power density disclosure satisfy that the demand in the industry to compressor small size, ensure to realize more in the case that compressor volume is smaller Big moisture removal reduces complete machine manufacturing cost.

As a kind of specific implementation mode of compressor cooling line, it is preferable that the compressor cooling line includes Intermediate refrigerant fairlead 21, intermediate refrigerant return pipe 22, the intermediate refrigerant fairlead 21 can will be cold in the condenser 2 Matchmaker drains back the compressor 1, and the intermediate refrigerant return pipe 22 is penetrated through with intermediate 21 pipeline of refrigerant fairlead, by institute Intermediate refrigerant fairlead 21 is stated to be drained in the condenser 2.It is cold using intermediate refrigerant fairlead 21, centre in the technical solution Refrigerant in the condenser 2 is led to refrigerant of the realization of the compressor 1 by lower temperature in condenser 2 by matchmaker's return duct 22 Cooling to compressor 1 keeps flowing to for refrigerant more controllable.

Further, the condenser 2 has the first refrigerant inlet 23, the first refrigerant exit 24, the intermediate refrigerant Fairlead 21 is set on the condenser 2 between first refrigerant inlet 23 and first refrigerant exit 24；And/or institute State the condenser 2 that intermediate refrigerant return pipe 22 is set between first refrigerant inlet 23 and first refrigerant exit 24 On.The refrigerant in the condenser 2 is drawn from the medium position of the condenser 2 in the technical solution, on the one hand can be protected It is relatively low to demonstrate,prove the refrigerant temperature drained, so as to more efficiently cool down the compressor, on the other hand, after heat absorption vaporization Refrigerant is back to again in the condenser 2, can fully be blended with refrigerant therein, is ensured as much as possible not to evaporation Condensation effect in device 4 has an impact.

For a kind of specific implementation mode of the compressor cooling line and the relationship of the condenser 2, it is preferable that institute Compressor cooling line is stated to be series between first refrigerant inlet, 23 and first refrigerant exit 24.Concatenated compressor cooling Pipeline can ensure stability of the refrigerant in terms of flow in the condenser 2.

Certainly, the compressor cooling line can also be parallel to first refrigerant inlet, 23 and first refrigerant exit 24 Between, but at this time due to being to use parallel way to flow back to refrigerant, it in a way can be to cold in the condenser 2 Matchmaker's pressure generates more detrimental effect, but can still realize the cooling effect to the compressor 1, certainly, it is preferred that It is the caliber less than first refrigerant inlet 23 by the pipe diameter determing of the intermediate refrigerant fairlead 21；The centre and/or The pipe diameter determing of refrigerant return pipe 22 is the caliber less than first refrigerant inlet 23, can favorably avoid aforementioned use at this time Adverse effect of the parallel way to cold medium flux and pressure.

The compressor 1 positioned opposite that can be provided in of the compressor cooling line and the compressor 1 Peripheral side, but the cooling effect of this mode is relatively limited, it is therefore preferred that the compressor cooling line further includes in shell Line segments 25, line segments 25 are located in the shell of the compressor 1 in the shell.By the way that pipeline in shell inside housings is arranged The component of 25 pairs of 1 enclosure interiors of compressor of section is after especially driving motor cools down, by line segments 25 in the shell Heat is taken out of the inside of the compressor 1 by refrigerant, and cooling effect is more.

In order to enable line segments 25 and the heat dissipation relative area of the component in 1 shell of the compressor in the shell to increase Greatly, and then air cooling effect is further increased, it is preferable that line segments 25 have pigtail and/or coil section in the shell, more Further, the driving motor setting is formed by the helical pipeline section in central space.
