Second embodiment

Referring to fig. 6 and 7 in combination, the present utility model provides a dehumidifier 10 for reducing indoor air humidity. The dehumidifier 10 includes a cabinet 200, an top outlet cover plate 100, a blower 300, a compressor 400, a condenser 500, a throttling device (not shown), and an evaporator 600. The basic structure and principle of the top-outlet cover plate 100 and the technical effects thereof are the same as those of the first embodiment, and for brevity, reference is made to the corresponding contents of the first embodiment where the description of the embodiment is not mentioned.

In this embodiment, the blower 300, the compressor 400, the condenser 500, the throttling device and the evaporator 600 are all installed in the casing 200, and the cover plate body 110 is connected to the top of the casing 200, wherein the compressor 400, the condenser 500, the throttling device and the evaporator 600 are connected end to end and combined to form a refrigerant flow path for flowing the refrigerant. During the flow of the refrigerant, the compressor 400 is configured to compress the refrigerant and deliver the high-temperature and high-pressure gaseous refrigerant to the condenser 500; the condenser 500 is used for exchanging heat with the refrigerant to cool the high-temperature and high-pressure gaseous refrigerant into a low-temperature and high-pressure liquid refrigerant, and enabling the liquid refrigerant to flow to the throttling device; the throttling device is used for throttling the refrigerant to change the low-temperature high-pressure liquid refrigerant into the low-temperature low-pressure liquid refrigerant and enable the low-temperature low-pressure liquid refrigerant to flow to the evaporator 600; the evaporator 600 is used for exchanging heat with the refrigerant to change the low-temperature low-pressure liquid refrigerant into low-pressure gaseous refrigerant and make the low-temperature low-pressure gaseous refrigerant flow back to the compressor 400. In this process, the blower 300 generates negative pressure to suck indoor air into the cabinet 200 and sequentially pass through the evaporator 600 and the condenser 500 to form an air-out flow, which is finally blown upward through the air outlet 111 of the cover plate body 110 to realize a dehumidifying function.

Specifically, in the process that the air-out airflow passes through the evaporator 600, the low-temperature low-pressure liquid refrigerant in the evaporator 600 absorbs heat of the air-out airflow, so that moisture in the air-out airflow is condensed on the evaporator 600 and forms condensation, at this time, the air-out airflow is cooled, and the low-temperature low-pressure liquid refrigerant is warmed to form a low-pressure gaseous refrigerant, so that the dehumidification function is realized. In the process that the air-out airflow passes through the condenser 500, the air-out airflow absorbs the heat of the high-temperature and high-pressure gaseous refrigerant in the condenser 500, and at this time, the air-out airflow is warmed (recovered to be close to the indoor temperature), and the high-temperature and high-pressure gaseous refrigerant is cooled to form a low-temperature and high-pressure liquid refrigerant.

Further, since the air-out airflow is cooled and then warmed in the process of passing through the evaporator 600 and the condenser 500 once, and finally reaches the degree close to the indoor temperature, the air-out airflow blown out from the air outlet 111 does not greatly affect the indoor temperature, and the user experience is improved.

The beneficial effects of the dehumidifier 10 of the embodiment of the present utility model are the same as those of the first embodiment, and will not be described again here.

Although the present utility model is disclosed above, the present utility model is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the utility model, and the scope of the utility model should be assessed accordingly to that of the appended claims.
