Description
Technical field
The present invention relates to a kind of heat pump clothes-drying device, a kind of heat pump washing-drying integral machine reduces the fixed installation structure of heat pump module vibrating noise.
Background technology
Existing heat-pump-type clothes drying device is provided with following air circulation duct: the hot-air that adds being carried out heating by the condenser in heat pump circulating system is admitted to equipped with in the hothouse of medicated clothing, the humid air having captured moisture from medicated clothing is sent back at vaporizer dehumidify, air after dehumidifying is heated by condenser again, and sends in hothouse.
The Chinese patent of Application No. 200610153406.9 discloses the heat pump of a kind of drying air that generation can be made to circulate between hothouse and heat pump and realizes the clothes drying device of stable operation.Wherein, the heater in heat pump the air carrying out heating is sent into as in the steel ladle of hothouse, returns to heat pump, heat extractor delivers to heater after dehumidifying again, form air circulation duct after the air through filter unit that steel ladle is discharged.Filter unit is provided with lint filter, and is provided with the pipeline being connected with air outlet and air induction port.
The Chinese patent of Application No. 200410097855.7 discloses a kind of clothes drying device, including: heat pump assembly；Drying air is guided heat extractor, radiator and the air channel of the drying room equipped with medicated clothing to heat pump assembly；The aerator of drying air is sent in described air channel；With control device.In drying operating process, compressor and aerator operate；When drying operation occurs to interrupt, control device and make compressor stop the time of regulation.
Heat pump assembly after improvement is by heat pump modularity, is arranged on the base plate of washing machine bottom after being assembled into an integral module, and the perforation utilizing bolt to pass heat pump module bottom periphery is fixed by nut screwing clamping after the installing hole of base plate with corresponding；Because compressor piston or the rotor of heat pump module are high-speed rotating component, the vibration of compressor can be delivered on bottom plate of washing machine by the fixed component of heat pump module, produces noise.Therefore at heat pump module and bottom plate of washing machine fixed position, vibration-absorptive material is installed, again owing to the fixing yardstick of bolt is without location, physical location may that height be had to have be low because of operator's difference, the actual fixed position run-off the straight of compressor, the vibration of compressor can strengthen, and the vibration being delivered to base plate by module is increased.
Additionally vibration-absorptive material has elasticity, after the excess compression by fixing bolt, can lose due damping effect, and heat pump module forms Hard link with base plate, and the vibration being delivered to base plate strengthens, and then produces bigger noise.
In view of this special proposition present invention.
