Description

dehumidifier

technical field

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

Background technique

Dehumidification is to remove excess water vapor in the air according to the requirements of water vapor content in the air in life or production. The principle is to condense excess water vapor in the air into water through a dehumidifier, so as to reduce the moisture content of the air and make it meet the requirements. At present, there are two commonly used methods of household dehumidification: one is physical adsorption dehumidification, and the other is electronic refrigeration dehumidification. Physical adsorption dehumidification is the use of chemical absorbents or desiccants to absorb water molecules in the air to reduce air humidity. After a period of use, it will fail due to moisture absorption or chemical reactions. In contrast, electronic refrigeration dehumidification has obvious advantages because of its good dehumidification effect, large dehumidification capacity, and long-term use. Electronic refrigeration dehumidification is to cool the air through semiconductor refrigeration chips, so that the water vapor in the air will condense on the evaporator to achieve the dehumidification effect. However, the air circulation of the existing dehumidifiers mostly uses a horizontal air outlet method to supply air. Because the cold air tends to settle, the current air outlet method of the dehumidifier is likely to prevent all the air from the bottom of the air duct, which affects the air supply. amount, thereby weakening the dehumidification effect.

detailed description

The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings of the utility model. Obviously, the specific implementation described is only a part of the embodiments. Other embodiments obtained under the premise of labor are all within the protection scope of the present utility model.

Referring to Fig. 1, the dehumidifier of the present invention includes a housing 1, a partition plate 4 is arranged inside the housing to divide the housing into a dehumidification area and a heat dissipation area, a control circuit board, a semiconductor refrigeration chip 2, and a semiconductor refrigeration chip The cold pole and the hot pole are respectively attached to the cold end heat exchanger 3 and the hot end heat exchanger 5. The water receiving box 8 is arranged at the bottom of the shell. The dehumidification area and the heat dissipation area are left and right structures. The dry and cold air enters the heat dissipation area through the bottom air outlet of the partition plate and leaves from the air outlet on the top of the housing.

After adopting this structure, the dry and cold air after dehumidification is drawn from the dehumidification area, enters the heat dissipation area to exchange heat with the heat exchanger at the hot end, and leaves the dehumidifier from the top of the shell after the temperature returns to normal temperature. The cold air at the bottom of the dehumidification area can all enter into the heat dissipation area, so that the air supply volume of dry air is greatly increased, and the dehumidification effect is obviously improved.

Since the temperature range of the semiconductor refrigeration chip is set to start and stop, it can fully ensure that the temperature of the cold aluminum of the dehumidifier is higher than the freezing point of water, effectively preventing it from freezing and affecting the condensation of humid air.

The bottom of the heat dissipation area is provided with a water removal structure inclined to the water receiving box. The water-removing structure is a water-removing tank or a water-removing plate 7 inclined downward.
