Negative pressure drying device

Abstract

The invention relates to the field of drying devices, in particular to a negative pressure drying device. The negative pressure drying device comprises a box body. A negative pressure pump is arranged below the box body and connected to a controller on the box body. The box body is communicated with the air inlet end of the negative pressure pump through a valve. The box body is internally provided with a plurality of sets of convection holes corresponding to one another in position. The convection holes in the same set are correspondingly connected to the air inlet end and the air outlet end of the negative pressure pump through valves respectively, and an annular circulating channel is formed. The air outlet end of the negative pressure pump is connected to an exhaust port in the box body through a valve. The controller is sequentially connected with valves in the box body and controls the valves. The drying device for clothes, shoes and life articles provides a vacuum negative pressure drying area, increases the moisture evaporation rate of the clothes and improves the drying efficiency.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a vacuum drying equipment for household shoes and the like. Background technique [0002] In the two seasons of winter and spring, due to the lack of sunlight, if there is continuous rainy weather, the clothes to be dried cannot be completely dried for a long time. Therefore, people choose to use drying equipment to dry clothes, or dry some items that need to be dried quickly for dry storage. However, the existing drying equipment generally only uses hot air to directly dry, and then heats and dehumidifies and dries. Although this drying has completed the drying needs, it requires a lot of energy and consumes a lot of power. At the same time, it directly discharges air with a high humidity. Waste heat energy and affect the indoor environment. Contents of the invention [0003] The purpose of the present invention is to: aim at the above technical problems, to provide a drying ...
