Deicing method and device of dehumidifier defrosting tray

Abstract

The invention discloses a deicing device of a dehumidifier defrosting tray. The deicing device comprises a dehumidifier body, a first heat exchanger, a second heat exchanger, a compressor, a pressurereducer, a draught fan, a four-way reversing valve and a temperature detector are arranged in the dehumidifier body, wherein the temperature detector is arranged on the first heat exchanger. The draught fan is located at the rear end of the second heat exchanger, the first heat exchanger is located at the front end of the second heat exchanger, two ends of the first heat exchanger are correspondingly connected with the pressure reducer and one end of the four-way reversing valve, two ends of the second heat exchanger are correspondingly connected with the pressure reducer and the other end ofthe four-way reversing valve, the other two ends of the four-way reversing valve are connected with the two ends of the compressor, the defrosting tray is arranged below the first heat exchanger and the second heat exchanger, and the compressor is located below the defrosting tray. The invention further discloses a deicing method of the dehumidifier defrosting tray. The energy-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of dehumidifiers, and particularly designs a deicing method and a deicing device for a water tray of a dehumidifier. Background technique [0002] Dehumidifiers are also known as dehumidifiers, dryers, and dehumidifiers. They can generally be divided into two categories: civil dehumidifiers and industrial dehumidifiers, and belong to a part of the air-conditioning family. Usually, a conventional dehumidifier consists of a compressor, a heat exchanger, a fan, a water tank, a casing and a controller. [0003] Its working principle is: the humid air is drawn into the machine by the fan, and passes through the heat exchanger. At this time, the water molecules in the air condense into water droplets, and the dried air after treatment is discharged outside the machine. This cycle keeps the indoor humidity at a suitable level. Relative humidity, the refrigerant circulation process of the dehumidifier is as follows...

Problems solved by technology

[0004] The current dehumidifiers are prone to frosting when operating at low temperatures, and generally need to be defrosted. During the defrosting process, due to the low temperature, it is easy to cause the water tray to freeze. Therefore, a heating wire is installed at the bottom of the water tray. The heating process of the water tray realizes the function of melting ice, but because the heating wire needs to be reset, it leads to serious waste of energy, and how to design a method of melting ice with good energy saving effect is particularly important
