Embodiment Construction

[0026] The ultimate goal of drying clothes is to remove the moisture contained in the clothes. In order to remove the moisture in the clothes in a short time, people adopt various methods to achieve this goal. The method used by the clothes dryer is to increase the temperature and strengthen the surface air circulation. , increasing the evaporation area. Water has different boiling points at different air pressures, and the lower the air pressure, the lower the boiling point. Refer to Table 1 below for the corresponding relationship between the two. It can be seen from the data in the table that at 0.03*10 5 ~0.1*10 5 Under the pressure of Pa, water can boil at 24°C-45.8°C, that is, when the pressure is low enough, water can reach the boiling point at a lower temperature, even at normal temperature, and can realize rapid evaporation at a lower temperature. The clothes dryer of the present invention realizes fast evaporation of water at a relatively low temperature by creatin...

Abstract

The invention discloses a negative pressure type heat pump clothes dryer comprising a housing, a motor driving device and a control device. The clothes dryer further comprises a clothes drying roller, a heating device and a negative pressure device. The clothes drying roller comprises two parts of an outer cylinder, and an inner cylinder which is rotatably arranged in the outer cylinder; the opening of the front end of the inner cylinder is provided with a sealable door body; the negative pressure device is communicated with the interior of the inner cylinder to form the negative pressure in the inner cylinder; and the heating device is arranged between the outer cylinder and the inner cylinder to supply heat to the inner cylinder. The opening of the front end of the outer cylinder is provided with an outer cylinder door body; a protective ring is arranged at the periphery of a passage between the opening of the front end of the inner cylinder and the opening of the front end of the outer cylinder; and the negative pressure device is communicated with the inner cylinder through a hollow rotating shaft on the back end of the inner cylinder. The negative pressure type heat pump clothes dryer accelerates the clothes drying speed and reduces energy consumption.

Description

technical field [0001] The invention relates to a clothes dryer, in particular to a negative pressure heat pump clothes dryer which quickly dries clothes in a negative pressure state. Background technique [0002] In a drying mechanism used in a clothes dryer or a washer-dryer, a device for generating heated air often adopts a heater heating method in which air is heated by a heater. Existing electric heating dryers generally use heating wire as a heat source, which consumes a lot of energy and takes a long time to dry. In order to reduce energy consumption, a heat pump dryer has been developed, which uses a heat pump system to strengthen the recycling of heat, improve heat utilization efficiency, and reduce power consumption. [0003] The heat pump clothes drying device is provided with the following air circulation channel: the heated air heated by the heat radiator in the heat pump is sent into the drying room containing the clothes, and the moisture-absorbing air that h...
