Description
- The present disclosure relates to a technical field of clothes drying, in particular, relates to a clothes drying device applying a semiconductor thermoelectric cooler and a method for drying clothes using the drying device to dry clothes.
- A clothes drying device (e.g. a clothes dryer, a washer-dryer, etc.) generally comprises a clothes accommodating drum for accommodating the clothes to be dried, and a drying duct which is located outside the clothes accommodating drum and is communicated with the clothes accommodating drum. A drying airflow is blew into the clothes accommodating drum through the drying duct. When the drying airflow flows through the clothes accommodating drum, remained moisture of the clothes in the clothes accommodating drum is heated into water vapor, the water vapor flows out from the clothes accommodating drum and flows into the drying duct with the air, and the water vapor is condensed in the upstream section of the drying duct. The relatively dry air after condensation is continued to flow in the drying duct and flows into the clothes accommodating drum again for continuous circulation. The existing washer-dryer generally adopts the way of water cooling condensation, for the way of water cooling condensation, cold water is required to continuously be introduced into the drying duct during the clothes drying process, at the same time, the flow rate of the cold water in the drying duct is required to be controlled to be relatively small in order to save water as much as possible. Therefore, the condensing efficiency of the condensation way is relatively lower, and the water consumption of the condensation way is relatively larger. For the way of air condensation, it is required to use the room-temperature air outside the device to exchange heat with the humid and hot air in the drying duct. Since the way needs to exchange heat by the pipe wall, the condensation efficiency is quite lower, resulting in longer clothes drying time and higher energy consumption.
- In order to solve the above problems, the invention patent No. 201210387889.4 discloses a condensing device and a dryer having the condensing device. The condensing device comprises a semiconductor thermoelectric cooler.

A thermal insulating material is filled between the hot end heat releasing sheet and the cold end heat absorbing sheet to isolate the heat conduction of the hot end heat releasing sheet and the cold end heat absorbing sheet. The dryer also comprises a drying chamber and a circulating air duct of which two ends are communicated with the drying chamber. The condensing device is installed in the circulating air duct. During the flowing of the air in the circulating air duct, the air flows through the cold end heat absorbing sheet of the condensing device to be subject to condensation and dehumidification, in turn, flows through the hot end heat releasing sheet to be heated, and then, returns to the drying chamber. However, the device exists the following deficiencies:
- First of all, although the semiconductor thermoelectric cooler has two functions, i.e. both cooling and heating, the cooling power of a single cooling element of the semiconductor thermoelectric cooler is normal. It needs a plurality of unit components to meet the condensation requirements, which will increase the manufacturing cost or energy consumption.
- Moreover, in order to further improve the condensing effect, some clothes drying device only utilizes the heating function of the semiconductor module, a condensing device is separately arranged in the circulating duct, and the condensing device must depend on the cold source (such as electric driving, etc.) to achieve the cooling effect. For example, a Chinese invention patent No. 201210008372.X discloses a new type of dryer, which comprises a case and an inner drum, and also comprises an air duct, a semiconductor thermoelectric cooler, a condenser and an evaporator.

Theevaporation sector 81 forms the heat absorbing portion of the condensing module 3, and thecondensation sector 82 forms the heat releasing portion of the condensing module 3. - The working principle of the
vapor chamber 8 is same with that of the heat pipe, and the working principle of thevapor chamber 8 comprises four main steps, i.e. conduction, evaporation, convection and condensation. Thevapor chamber 8 is a dual-phase fluid device which is formed by the mode that pure water is injected into a container full of micro structures. The heat enters the vapor chamber from the outer high-temperature zone through heat conduction, the water around point heat source quickly absorbs the heat and vaporizes into the vapor, and a large amount of heat energy is taken away. Then using the latent heat ability of the vapor, the vapor in the vapor chamber diffuses to low-pressure zone from high-pressure zone, when the vapor is in contact with the inner wall with lower temperature, the vapor is quickly condensed into liquid and release heat energy. The condensed water flows back to the point heat source by the capillary action of the micro structures, to complete a heat transfer cycle and to form a dual-phase circulation system that the water and the vapor coexist. The vaporization of the water in the vapor chamber is continued to be carried out, the pressure in the vapor chamber will maintain equilibrium with the change of the temperature. The value of the thermal conductivity coefficient is relatively low when the water operates at a lower temperature, but the vapor chamber can also operate at 5° C. or 10° C. because the viscosity of the water will change at different temperature. Because the backflow of the liquid depends on the capillary action, the vapor chamber is less affected by gravity, so that the design space of the application system can be used at any angle. The vapor chamber needs no power and any moving components, and the vapor chamber is a completely sealed passive device. - A method for drying clothes adopting the clothes drying device of the above embodiments, comprises the following steps:
