Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air treatment device, and more particularly to an air treatment device with a function of adjusting the humidity of the air.

With the improvement of living standards, people's demands for office environment and living environment are increasing more and more. For example, not only is the need for air treatment equipment that adjusts environmental temperature, such as air conditioners for cooling or heating, but also the need for air treatment equipment that adjusts environmental humidity, such as dehumidifiers and dryers, is increasing day by day. rising.

Some conventional dehumidifiers use the refrigerant compressing characteristics of the compressor to dehumidify. There are drawbacks such as loud running noise.

Dehumidifying rotor type dehumidifiers have been proposed to address such drawbacks of conventional dehumidifiers. In this dehumidifier, the dehumidifying rotor is manufactured using, for example, zeolite as a material. By utilizing the hygroscopic properties of this dehumidifying rotor, it is possible to realize a function of adjusting the humidity of the air without using a compressor (see, for example, Patent Document 1: Chinese Utility Model No. 202096871). .

In the dehumidifying rotor type dehumidifier described above, an electric heating device is provided to heat and regenerate the area of the dehumidifying rotor after absorbing moisture by utilizing the characteristics of the dehumidifying rotor that it can absorb moisture at normal temperature and release moisture at high temperature. Therefore, a long-time dehumidifying function can be easily realized.

However, in the above-mentioned dehumidifying rotor type dehumidifier, in addition to a blower unit that dehumidifies the inside of the air intake device with a dehumidifying rotor and sends the dehumidified air into the room, , it is necessary to further install a dedicated blower to blow air to the electric heating device, and use the air after passing through the electric heating device to heat the area of the dehumidifying rotor after moisture absorption. As a result, the entire device becomes complicated, resulting in an increase in manufacturing cost.

SUMMARY OF THE INVENTION The present invention has been devised to solve the above-mentioned problems. It is an object of the present invention to provide a processing apparatus.

In order to achieve the above objects, the present invention provides the following air treatment device. The air treatment device has a body. The body has an inlet, a first outlet, and a second outlet. A fan assembly, a humidity control rotor, and a heating assembly are provided within the body. The fan assembly has an air inlet, a first air inlet, and a second air inlet. The humidity conditioning rotor has an axis of rotation substantially parallel to the axis of rotation of the fan rotor of the fan assembly, and has a moisture absorption area and a moisture release area adjacent to each other in a circumferential direction about the axis of rotation of the humidity conditioning rotor. During operation of the fan assembly, the airflow sucked into the main body through the air inlet passes through the moisture absorption area and enters the air inlet of the fan assembly before dividing into two paths. One is a route in which air is blown out from the first air supply port, passes through the moisture desorption area, and is discharged from the first outlet, and the other is a route in which the air is blown out from the second air supply port to the second outlet. This is the route through which the The heating assembly has a heating section. The heating unit heats at least a portion of the moisture release area that is closer to the upstream side in the rotation direction of the humidity conditioning rotor. The first air supply port blows air to at least a portion of the moisture release area that is closer to the upstream side in the rotational direction of the humidity conditioning rotor. The direction of rotation of the fan rotor and the direction of rotation of the humidity control rotor are the same.

Here, "the humidity control rotor has a rotation axis substantially parallel to the rotation axis of the fan rotor of the fan assembly" means that the rotation axis of the humidity control rotor and the rotation axis of the fan rotor of the fan assembly are strictly parallel. The rotation axis of the humidity control rotor may be slightly tilted with respect to the rotation axis of the fan rotor of the fan assembly due to manufacturing or assembly errors, deformation due to vibration or heat during operation, etc. Also included if any.

According to the air treatment device of the present invention, the fan assembly has an air intake and a first air supply opening, and when the fan assembly operates, air passes through the moisture absorption area of the humidity control rotor and enters the air intake of the fan assembly. A part of the flow is blown out from the first air outlet, passes through the moisture desorption area, and is then discharged from the first outlet. As a result, there is no need to provide a dedicated air blower to blow air to the heating assembly, and the air flow blown out from the first air outlet of the fan assembly is used to achieve the moisture release effect of the moisture release area of the humidity control rotor. This contributes to simplification of the structure of the entire device.

Further, according to the air treatment apparatus of the present invention, the heating part of the heating assembly heats at least a portion of the humidity desorption area that is closer to the upstream side in the rotation direction of the humidity conditioning rotor. Compared to the case where only the portion closer to the downstream side in the rotation direction is heated, the area of the moisture release area that actually functions can be easily increased, contributing to the improvement of the moisture release effect of the moisture release area of the humidity control rotor. As a result, the dehumidification efficiency of the humidity control rotor increases.

Further, according to the air treatment apparatus of the present invention, the heating part of the heating assembly heats at least a portion of the moisture release area closer to the upstream side in the rotation direction of the humidity conditioning rotor, and the first air supply port at least Air is blown to a portion of the humidity area that is closer to the upstream side in the rotation direction of the humidity control rotor. Further, the rotating direction of the fan rotor is the same as the rotating direction of the humidity control rotor. As a result, compared to the case where the rotation direction of the fan rotor and the rotation direction of the humidity control rotor are different, the airflow blown out from the first air supply port of the fan assembly is more likely to spread over the entire moisture desorption area. Since the temperature of the rotor is made more uniform, it contributes to the improvement of the moisture release effect of the moisture release area of the humidity control rotor. As a result, the dehumidification efficiency of the humidity control rotor increases.

It may be difficult to reach the portion closer to the downstream side in the rotation direction. Therefore, if the downstream portion is heated by the heating unit, the temperature in the vicinity of the downstream portion tends to rise too much, which poses a potential safety risk. On the other hand, if a buffer portion that does not heat the moisture release area is provided at a position downstream of the heating portion in the rotation direction of the humidity control rotor, it is easy to avoid the potential safety risk described above. Furthermore, by providing a buffer portion partially corresponding to at least a portion of the humidity desorption area closer to the downstream side in the rotation direction of the humidity conditioning rotor, the temperature of the moisture desorption area portion of the humidity conditioning rotor after passing through the buffer portion is reduced. can be lowered to some extent. As a result, after the moisture desorption area of the humidity control rotor receives heat, the temperature rises excessively, which affects the efficiency of moisture absorption when the moisture desorption area rotates and reaches the moisture absorption area. can be prevented.
