According to the invention, the dehumidifier is improved, so that after the humid air flows through the first evaporator for cooling and dehumidifying (first-step dehumidifying), the low-temperature saturated air continuously flows to the air duct system. Because the high-speed rotatory fan blade in the air duct system is to the pressure boost of humid air for saturated humid air pressure rises, then correspondingly, its moisture content reduces, and the saturated humid air after coming out from first evaporimeter will have some and will continue to condense into the drop of water (dehumidification of second step) this moment, and the air that further recycles two fans sent collides the mixture (dehumidification of third step) and makes the air can condense at second evaporimeter department better, reaches better dehumidification effect.
To further illustrate the technical solution of the present invention, the following specific examples are provided as shown in fig. 1 to 5.

In this embodiment, two centrifugal fans are used in the air duct system of the dehumidifier, so that the near-saturated humid air dehumidified by the first evaporator 3 is divided into two air flows, the two air flows are pressurized and accelerated once by the two centrifugal fans respectively (to generate a part of condensed water), the two air flows reversely collide with each other in the pressurizing cavity 7, at this time, secondary pressurization is performed (to generate another part of condensed water), and finally the humid air enters the second evaporator 4 for further condensation and dehumidification. Specifically, the method comprises the following steps: after the air subjected to the first-step dehumidification treatment is shunted and enters the first centrifugal fan 1 and the second centrifugal fan 2 for pressurization, the second-step dehumidification treatment is completed; the air after the second dehumidification enters the pressurizing cavity 7 through the first inlet of the pressurizing cavity and the second inlet of the pressurizing cavity and then is collided and mixed to finish the third dehumidification.

In this embodiment, the dehumidifier further includes: a throttling element 5.

Wherein the condenser, the second evaporator 4 and the first evaporator 3 are all arranged in the middle air supply channel. Based on the air supply channel, the air to be dehumidified can pass through the first evaporator 3, the centrifugal fan set, the second evaporator 4 and the condenser in sequence to complete a multi-stage dehumidification process. In the air circulation process of the dehumidifier, the wet air state is reasonably utilized, multistage dehumidification is realized, and the dehumidification capacity of the dehumidification system is maximized.
Example 2
In this embodiment, a dehumidification control method of a dehumidifier is provided, and the dehumidification control method can be used to control the dehumidifier to perform dehumidification.
Specifically, the dehumidification control method comprises the following steps:
conveying the air entering the dehumidifier to a first evaporator 3 for a first-step dehumidification treatment;
respectively sucking the air subjected to the first-step dehumidification into a first centrifugal fan 1 and a second centrifugal fan 2 of a centrifugal fan set to perform second-step dehumidification;
and (3) colliding and mixing the air subjected to the second-step dehumidification treatment by the first centrifugal fan 1 and the second centrifugal fan 2 to finish the third-step dehumidification treatment.
In some optional manners, the dehumidification control method further includes: performing a fourth dehumidification treatment on the air subjected to the third dehumidification treatment by using a second evaporator 4; and conveying the air subjected to dehumidification treatment in the fourth step to a condenser for heat exchange treatment so as to cool the condenser, and simultaneously realizing temperature rise of the air.
The dehumidification process of the present invention will be described with reference to the structure and the dehumidification principle of the dehumidifier.
As shown in fig. 1, the ambient air at normal temperature and pressure first flows through the first evaporator 3, and then directly flows into the air duct system after exchanging heat with the refrigerant on the first evaporator 3, at which time the first step of dehumidification (condensation dehumidification) occurs. As shown in fig. 5, t represents the air temperature, Pa represents the air pressure, and d represents the humid air moisture content. When the relative humidity is constant (here, the relative humidity is 100% for example), the pressure of the humid air is plotted against the moisture content thereof. It can be seen from the figure that when the relative humidity of the air is constant while the temperature is maintained, if the air pressure is increased, the moisture content of the air is correspondingly reduced, and at the same time, the moisture is separated out from the wet air. After exiting the first evaporator 3, the humid air becomes low temperature saturated air and enters the duct system. The air duct system consists of a centrifugal impeller and a volute, and centrifugal force generated by rotating the impeller at high speed applies work to gas to increase the speed of the gas and increase the pressure. Since the air is saturated air at a low temperature, the moisture content of the air decreases after the air pressure increases, and partial moisture is condensed due to the increase of the air pressure. At this time, the dehumidification system takes place the second dehumidification (pressurized dehumidification).
As shown in fig. 2, two centrifugal fans are arranged in the air duct system of the dehumidifier, and air outlets of the two centrifugal fans are oppositely arranged. After passing through the first evaporator 3, the wet air is divided into two air flows and enters the two centrifugal fans respectively. As shown in fig. 3 and 4, the simulated gas pressure and flow rate after entering the pressurizing cavity 7 are respectively divided into two streams. The two air flows are firstly pressurized in the two centrifugal fans and then discharged, and then the two air flows collide in the pressurizing cavity 7. Because the two air flows have larger air flow velocity and collide reversely, the air generates speed reduction and pressurization at the collision part. At this point the gas velocity is locally reduced instantaneously and the pressure rises, creating a high pressure zone. As shown in the graph of fig. 5, when the moisture content of the two portions of low-temperature saturated air is reduced, condensed water is separated out, and the dehumidification system performs the third step of dehumidification (pressurized dehumidification).
The humid air after double pressurization of the air duct system is in a condensation state, flows to the second evaporator 4 and then is condensed and dehumidified on the second evaporator 4, and at the moment, the dehumidification system performs fourth dehumidification and finally enters the condenser for heat exchange.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
