Please refer to Fig. 1 to Fig. 3, the present invention proposes a dehumidifier 100, including:

A housing (not shown), the housing is provided with a first air inlet, a second air inlet, a first air outlet and a second air outlet, and forms a first air duct communicating with the first air inlet and the first air outlet , and the second air duct connecting the second air inlet and the second air outlet;

The supplementary air condenser 10, the supplementary air condenser 10 is arranged in the first air duct, and is arranged corresponding to the first air inlet and the first air outlet;

a dehumidification assembly 30, the dehumidification assembly 30 is arranged in the second air duct, and is arranged corresponding to the second air inlet and the second air outlet; and

Two fans 50, one fan 50 is arranged in the first air channel, and is located between the air supply condenser 10 and the first air outlet, the air is introduced into the first air channel from the first air inlet, and after passing through the air supply condenser 10, It is blown out from the first air outlet; another fan 5 is set in the second air duct, and is located between the dehumidification assembly 30 and the second air outlet, and the air flow is introduced into the second air duct from the second air inlet, and passes through the dehumidification assembly 30 After that, it is blown out from the second air outlet.

In the technical solution of the present invention, by providing a first air inlet, a second air inlet, a first air outlet, and a second air outlet on the casing, and forming a first air duct communicating with the first air inlet and the first air outlet, And the second air passage connecting the second air inlet and the second air outlet; the dehumidification assembly 30 is set corresponding to the second air inlet and the second air outlet, and the air entering the air passage from the second air inlet is dehumidified by the dehumidification assembly 30, Dry air with low temperature is formed, which is blown out from the second air outlet; the supplementary air condenser 10 is set corresponding to the first air inlet and the first air outlet, and the air entering the air duct from the first air inlet can be fully combined with the supplementary air condenser 10 for heat exchange, the supplementary air condenser 10 increases the temperature of the outlet air so that the temperature of the outlet air can reach the room temperature requirement. Installing the supplementary air condenser 10 is equivalent to increasing the total heat exchange area of the condenser in the dehumidifier, making the heat exchange efficiency of the condenser high and reducing the energy consumption of the whole machine.

Further, due to the limitations of the structure of the blower fan 50 itself, the air intake ratio of the blower fan 50 is even than the wind outlet. In the technical solution of the present invention, a blower fan 50 is arranged between the supplementary air condenser 10 and the first air outlet, and the other blower fan 50 Located between the dehumidification assembly 30 and the second air outlet, after the fan 50 is started, the air is sucked into the first air passage and the second air passage through the first air inlet and the second air inlet, so that the air is drawn from the first air inlet and the second air inlet. The air entering the tuyere can evenly pass through the supplementary air condenser 10 and the dehumidification assembly 30, and the heat exchange efficiency with the supplementary air condenser 10 and the dehumidification assembly 30 is high, further reducing the energy consumption of the whole machine.

Furthermore, the two fans 50 can be controlled separately, so that the air volumes passing through the supplementary air condenser 10 and the dehumidification assembly 30 can be controlled respectively, so that the air output ratio of the dehumidifier 100 can be adjusted.

In an embodiment of the present invention, the supplementary air condenser 10 and the dehumidification assembly 30 are vertically arranged. The supplementary air condenser 10 and the dehumidification assembly 30 arranged in the longitudinal direction make the whole machine occupy a small area, and the usable space in the casing is more reasonable. It can be understood that the make-up air condenser 10 and the dehumidification assembly 30 can also be arranged in a horizontal direction, so that the whole machine occupies a larger area and can be placed more stably.

In an embodiment of the present invention, the make-up air condenser 10 is located above the dehumidification component 30 . Since the supplementary air condenser 10 is smaller and lighter than the dehumidification assembly 30, the dehumidification assembly 30 is arranged at the bottom and the supplementary air condenser 10 is arranged at the top, so that the dehumidifier 100 is placed more stably and is not easy to dump.

In an embodiment of the present invention, a water receiving tray (not shown) is further provided in the casing, and the water receiving tray is arranged under the dehumidification assembly 30 . When the dehumidification component 30 dehumidifies the air, condensed water will be generated, and the condensed water will flow down along the dehumidifying component 30 into the water receiving tray. Furthermore, the supplementary air condenser 10 is located above the dehumidification assembly 30 , and a water receiving tray is provided below the dehumidification assembly 30 , which not only facilitates the collection of condensed water, but also makes effective use of the space inside the housing.

In an embodiment of the present invention, the dehumidification assembly 30 includes a dehumidification evaporator 31 and a dehumidification condenser 33 stacked along the air intake direction of the second air inlet.

The air that enters the air duct from the second air inlet first passes through the dehumidification evaporator 31. Since the temperature of the dehumidification evaporator 31 is lower than that of the part of the air, this part of the air passes through the dehumidification evaporator 31 and is carried out with the dehumidification evaporator 31. Heat exchange, the moisture in the air will condense into water droplets when it is cold, so that the water content of the air passing through the dehumidification evaporator 31 is low, but the temperature is low, while the temperature of the dehumidification condenser 33 is high, and the air after passing through the dehumidification evaporator 31 The air exchanges heat with the dehumidification condenser 33 , so that the temperature of the air after passing through the dehumidification condenser 33 is higher and close to the indoor temperature.

Referring to Fig. 3, in one embodiment of the present invention, the dehumidifier 100 also includes a compressor 20 disposed in the casing, the compressor 20, the supplementary air condenser 10, the dehumidification condenser 33 and the dehumidification evaporator 31 are sequentially connected to form a closed tube There is a refrigerant in the pipeline, and the refrigerant circulates along the direction of the compressor 20, the supplementary air condenser 10, the dehumidification condenser 33 and the dehumidification evaporator 31.

The refrigerant is compressed by the compressor 20 to form a high-temperature and high-pressure vapor refrigerant, which flows to the supplementary air condenser 10. The high-temperature and high-pressure vapor refrigerant flows through the supplementary air condenser 10 for initial cooling, and then flows to the dehumidification condenser 33 for further cooling. , it can be seen that the temperature of the supplementary air condenser 10 is higher than the temperature of the dehumidification condenser 33; the air entering the air duct from the second air inlet is firstly dehumidified and cooled by the dehumidification evaporator 31, and then blows to the dehumidification condenser 33. There is a sufficiently large temperature difference between the air behind the dehumidification evaporator 31 and the dehumidification condenser 33, which can effectively perform heat exchange. The refrigerant is equivalent to a gradient heat exchange process on the supplementary air condenser 10 and the dehumidification condenser 33. There is a relatively suitable temperature difference between the air and the supplementary air condenser 10 and the air and the dehumidification condenser 33 , and the heat exchange efficiency is relatively high, thereby improving the heat exchange efficiency of the dehumidifier 100 as a whole.

The makeup air condenser 10 and the dehumidification condenser 33 can be two separate condensers or an integral condenser structure. When the supplementary air condenser 10 and the dehumidification condenser 33 are an integral condenser structure, the production and installation of the dehumidifier 100 are more convenient, and the heat exchange area of the condenser in the dehumidifier 100 can also be increased to improve the energy efficiency of the whole machine Effect. When the supplementary air condenser 10 and the dehumidification condenser 33 are two separate condensers, since the fins on the supplementary air condenser 10 and the dehumidification condenser 33 are not connected to each other, there will be no heat conduction between them, thereby The supplementary air condenser 10 and the dehumidification condenser 33 will not affect each other's heat exchange efficiency, so that both the supplementary air condenser 10 and the dehumidification condenser 33 can achieve a good heat exchange effect.

In an embodiment of the present invention, the supplementary air condenser 10, the dehumidification condenser 33 and the dehumidification evaporator 31 are all plate-shaped structures. The plate-type supplementary air condenser 10, dehumidification condenser 33, and dehumidification evaporator 31 can meet the installation requirements of air intake on one side and air outlet on the other side, and the heat exchange effect is good.

Referring to Fig. 2, in one embodiment of the present invention, the fan 50 includes a volute 51 and a wind wheel 53 disposed in the volute 51, the volute 51 is connected to the casing, and has an air inlet side and an air outlet side;

The air inlet side of the volute 51 located in the first air duct faces the supplementary air condenser 10, the air outlet side faces the first air outlet, the air inlet side of the volute 51 located in the second air duct faces the dehumidification assembly 30, and the air outlet side faces For the second air outlet.

The wind wheel 53 rotates to blow out the wind, and the volute 51 guides and gathers the wind blown by the wind wheel 53 , so that the wind wheel 53 has a higher wind blowing efficiency.

In one embodiment of the present invention, the blower fan 50 further includes a motor 55 connected to the air inlet side of the volute 51 , the rotating shaft of the motor 55 is connected to the wind wheel 53 and drives the wind wheel 53 to rotate.

The volute 51 is formed with a support on the air inlet side, and the motor 55 is fixed on the support, and the fixing effect of the motor 55 is good.

In one embodiment of the present invention, the fan 50 is a centrifugal fan; in another embodiment, the fan 50 is an axial fan. Centrifugal fans can change the flow direction of the air, and can increase the air volume and air pressure. The axial flow fan has axial air inlet and axial air outlet, and the air volume is large.

The dehumidifier in this embodiment is a horizontal type, and the housing is roughly square. The first air inlet and the second air inlet are located on the same side of the housing and arranged side by side along the vertical direction, and the first air outlet and the second air outlet are located on the other side of the housing.
