Description

Clothesdrier

Technical field

The utility model belongs to field of household appliances, is specifically related to a kind of wet clothes and article be carried out dry clothesdrier.

Background technology

Present widely used clothesdrier mostly adopts electrical heating, Steam Heating, hot air and hot water to heat the mode of equal energy source simple switched, comes wet clothes and article are carried out dried.The mode of these several heating, consumes energy is big, and drying efficiency is low, the time is long.Simultaneously, clothing is deposited in the machine after the drying, plays congee easily, and because the inhomogeneous clothes fiber that easily makes of heating is impaired.

Heat pump techniques is a kind ofly to cause it to produce the technology that phase transformation produces heat by compressed air, adopts heat pump techniques heating energy savings greatly.Heat pump comes down to a kind of heat lifting device, the effect of heat pump is a draw heat from surrounding environment, and it is passed to heated object (object that temperature is higher), its operation principle is identical with refrigeration machine, all according to contrary Carnot cycle work, different just operating temperature range is different.Usually heat pump assembly includes: compressor, condenser, evaporimeter, the pipeline that the pressure of the cold-producing medium of high pressure is carried out the throttling arrangement of step-down and connects these devices.By allowing working medium constantly finish the thermodynamic cycle process of evaporation (draw heat in environment) → compression → condensation (emitting heat) → throttling → evaporate again, thereby with the transfer of heat in the environment.

At present, in the prior art, the clothesdrier that does not also have the very desirable employing heat pump assembly of effect, for example: application number is: 200610153472.6, publication number is: CN1936161, name is called: the patent application of " clothes drying device " discloses a kind of clothes drying device, wherein, thus dry with the air drying clothes that in the air channel of radiator with heat pump assembly and heat dump, circulates.Because drying circulates in almost airtight air channel with air, there is not sufficient space that hot and cold gas is fully mixed, and can only exchange with outside air with limitation, can not in time the heat in the air channel be discharged to the outside, after warming in the air channel, can not adjust the compressed capability of heat exhaust and compressor well, can't prevent thoroughly that compressor variable from being running overload, then the temperature and pressure of cold-producing medium may surpass feasible value, causes entire machine to run well.Simultaneously, drying circulates in airtight air channel with air, can't successfully the moisture in the wet wash be discharged the effect that influence is dry.Radiator and heat dump are arranged in the position narrow in the air channel, and it is insufficient that air-flow and radiator and heat dump carry out heat exchange.

Summary of the invention

The purpose of this utility model is to provide a kind of clothes drying device, adopt heat pump assembly that heat energy is provided, but energy savings, and can guarantee that drying can not make the air channel overheated with air, and the temperature and pressure that causes cold-producing medium surpasses the situation generation of feasible value, and the moisture in the wet wash in time can be discharged outside the machine.

The utility model is achieved through the following technical solutions:

Clothesdrier includes:

Heat pump assembly, heat pump assembly is described to be included: compressor, condenser, evaporimeter, the pipeline that the pressure of the cold-producing medium of high pressure is carried out the throttling arrangement of step-down and connects these devices;
