Description

Dehumidifier

Technical Field

The utility model relates to the technical field of dehumidification, in particular to a dehumidifier.

Background

The existing dehumidifier 'sucks' moist air into the machine, condenses water vapor in the moist air into liquid water drops through a heat exchange system, and then 'discharges' the treated dry air out of the machine. By repeating the above steps, the relative humidity of the environment is reduced by the air circulation working principle. At present, dehumidifiers are mainly divided into two types: one is a condensing dehumidifier, and the other is a rotary dehumidifier. The condensing dehumidifier pumps moist air into the machine, then drives a heat exchanger consisting of an evaporator and a condenser through a compressor, condenses the moisture in the moist air pumped into small water drops and collects the small water drops, then discharges the treated dry warm air out of the machine, and repeatedly circulates in this way to reduce the indoor humidity.

However, most of the existing dehumidifiers still adopt traditional single-side air inlet and outlet, namely, the evaporator and the condenser are positioned on the same straight line with the fan, which not only results in insufficient dehumidification, but also has poor dehumidification effect, and meanwhile, the two evaporators have large volume and large volume, thus the whole dehumidifier has improvement.

In view of the problem that the existing dehumidifier has poor dehumidification effect caused by single-side air inlet and outlet and has large whole volume caused by larger volume of an evaporator and a condenser, the dehumidifier of the embodiment is provided with the air inlets 11 on the two side walls of the shell 1 and the air outlets 12 on the top of the shell 1 to form an air channel structure with two side air inlets and top air outlet, so that the air inlet quantity can be increased to improve the dehumidification effect; meanwhile, under the action of gravity, the air flow of the top air outlet can diffuse from high positions to the periphery, so that the experience of a user is improved.

More importantly, the semiconductor refrigeration sheet 21 is small in volume and weight in practical application, and the volume and weight of one semiconductor refrigeration sheet 21 are far smaller than those of a corresponding mechanical refrigeration device, for example, the conventional semiconductor refrigeration sheet 21 at present has the dimensions of 300mm long by 300mm wide by 400mm wide, and even only 1mm long by 1mm wide. Of course, the semiconductor refrigerating sheets 21 with various special sizes can be formulated according to actual requirements, so that the whole size of the dehumidifier can be effectively controlled, and the dehumidifier can be used or placed in multiple scenes by a user.
