Due to the need to improve indoor air, the application of air purification and humidification equipment is becoming more and more common. In addition to the traditional functions, household appliances such as air conditioners also begin to have other functions such as air purification and humidification. Installing water-washing air devices inside household appliances can improve Indoor air quality, take the air conditioner as an example. In order to maintain the indoor temperature balance and avoid the leakage of heat or cold, the air conditioner usually maintains the indoor space in a relatively closed environment. After using the air conditioner for a period of time, the indoor air The cleanliness of the air conditioner will decrease, and the air will become turbid. Therefore, the washing air purification device installed on the air conditioner can filter the dust or impurities in the indoor air by washing. The air purification device is usually equipped with a water tank, and the indoor air flow enters the room. The inside of the water tank is filtered and purified, dust and impurities are deposited in the water tank, and fresh and clean air flows out of the water tank, so that the cycle can keep the indoor air clean.

When the existing air purification device is in use, the water curtain installed inside the water tank is usually used to form a water curtain for purifying the air. The water rejection device is driven by a motor installed outside the water tank and rotates inside the water tank, and the external air enters the water tank. Passing through the water curtain can filter the dust and impurities in it, but the motor-driven water thrower needs to be driven through the rotating shaft, and a sealing structure needs to be set at the connection position at both ends of the rotating shaft, which leads to the overall driving structure of the water thrower. Complex, the production process The assembly efficiency is low, and the number of parts is large, which increases the manufacturing cost. At the same time, the water throwing parts are driven by the rotating shaft, and it is easy to get stuck. user experience.

In order to solve the above problems, this application provides a water washing air device and air conditioner. By changing the structure and driving mode of the water rejection parts, the overall structure of the water curtain formed by the water removal parts is simplified, thereby improving the assembly efficiency of the water washing air device. The manufacturing cost is reduced, and at the same time, jamming or noise generated during the rotation of the water thrower can be avoided, thereby improving user experience.

Embodiment one

This embodiment provides a water-washing air device, which is used to wash and filter indoor air to improve air quality. The water-washing air device can be installed independently or integrated in other household appliances. Specifically, it can be installed in air conditioners, In air purifiers, indoor fans and other equipment, and when integrated in the above-mentioned household appliances, they can operate synchronously with other functional components of the above-mentioned household appliances, and can also operate independently. This embodiment is specific to the washing air device The application scenarios are not limited.

Fig. 1 is a schematic structural view of the air washing device provided in Embodiment 1 of the present application, Fig. 2 is an exploded view of the air washing device provided in Embodiment 1 of the present application, and Fig. 3 is a water rejection in the air washing device provided in Embodiment 1 of the present application Figure 4 is a schematic diagram of the structure of the washing air device provided in Embodiment 1 of the present application. As shown in Figures 1 to 4, the washing air device 1 provided in this embodiment includes a water tank 10 and the water rejection assembly, the water tank 10 has a water-filled accommodation chamber 101, the water rejection assembly is arranged in the accommodation chamber 101, and can form a water curtain in the accommodation chamber 101, when external air enters the water tank 10, the water curtain can filter the air The dust and impurities in the water curtain can purify the air, and the air will take away part of the water vapor in the water curtain to a certain extent during the circulation process, so as to improve the indoor air freshness and improve the indoor air humidity at the same time.

Wherein, the water throwing assembly includes a water throwing member 20 and a water pumping assembly. The water throwing member 20 is rotatably installed on the water pumping assembly. When the water throwing member 20 rotates, water can be thrown out to form a water curtain. Specifically, the water throwing member 20 has a water spray channel, the water spray channel has a water inlet 201 and a plurality of water spray ports 202, and the water pumping assembly communicates with the water inlet 201, and under the action of the water pumping assembly, the cleaning water in the accommodation chamber 101 can be Enter the water spray channel to form a water flow, and the reverse extension line of the water outlet direction of each water spray port 202 has a distance from the rotation center of the water throwing member 20, that is, the reaction of the water flow ejected from the water spray port 202 to the water throwing member 20 There is a distance between the extension line of the extension line and the center of rotation of the water-repelling part 20, that is, the water spraying direction is along the circumferential direction of the water-repelling part, and the water spraying direction and the radial direction of the water-repelling part 20 do not coincide, so that the reaction of the water flow can be used for the water-repelling part. The water component 20 forms a rotational moment, so that the water flow is ejected from the water spout 202 and at the same time pushes the water throwing component 20 to rotate.

It should be noted that, unlike the motor-driven rotation method in the prior art, in the water washing air device 1 provided in this embodiment, the water throwing member 20 is driven to rotate by the reaction force when the water flow is sprayed from the water spray port 202, That is to say, in the prior art, there is the rotation of the moving parts first, and then the water flow is formed, but in this embodiment, the water flow is formed first, and then the water throwing member 20 is driven to rotate by the water flow. In addition, in this embodiment, water flow is continuously drawn into the water spray channel through the pumping assembly, so that the water throwing member 20 continues to rotate autonomously, and a water curtain is formed in the accommodation chamber 101. Using the force of the water flow to continuously rotate to form a water curtain, the structure is simpler, and fewer parts are required. During the production process, the assembly efficiency can be improved, and the manufacturing cost can be reduced at the same time.

In addition, since the rotation of the water throwing member 20 is an autonomous movement process realized by water flow, and does not need to be driven by moving parts, therefore, there will be no jamming and noise during the rotation process of the water throwing member 20 forming a water curtain, and the overall working process is smoother. .

Since the driving force for the rotation of the water jetting member 20 comes from the water flow, the rotational speed of the water jetting unit 20 depends on the magnitude of the reaction force generated by the water flow ejected from the water spray port 202, and under the condition that the shape and size of the water jet channel are determined, The force of the water flow depends on the flow rate of the water flow, so the speed of the water throwing member 20 can be controlled and adjusted by controlling the amount of water pumped by the pumping assembly, that is, the range of the water curtain can be adjusted.

The specific structure of the water throwing member 20 and the specific process of its rotation will firstly be described in detail below.

Fig. 5 is a cross-sectional view of the water-spinning element in the water-washing air device provided in Embodiment 1 of the present application. Please refer to Fig. 4 and Fig. 5 . Take the disc as an example, that is, the water throwing member 20 can be a water throwing plate, the rotation center of the water throwing member 20 can be the center of the disc, and the rotation plane of the water throwing member 20 is parallel to the disk surface of the disc.

Optionally, the water slinger 20 may be horizontally arranged in the accommodation cavity 101 to form a water curtain in the circumferential direction of the accommodation cavity 101 .

Wherein, the water inlet 201 can be located at the center of the water rejection member 20, like this, when the water removal member 20 rotates, the position of the water inlet 201 can be kept relatively fixed so as to communicate with the water pumping assembly, and a plurality of water jets 202 can be located at the center of the water rejection member 20. The outer edge of the water part 20 is distributed around the circumferential interval of the water part 20, and the water outlet direction of the adjacent water spouts 202 has an included angle, so that the water jets ejected from a plurality of water spouts 202 are used to drive the water jets simultaneously. The water part 20 rotates so that the water throwing part 20 forms a water curtain more stably. Simultaneously, the centrifugal force that the water-repelling member 20 makes the water flow produce is also more conducive to the formation of the water curtain during the rotation process.

Since the water flow ejected from each water jet 202 will cause the water jetting member 20 to generate a rotational moment, in order to ensure that the overall force of the water jetting unit 20 is more balanced, a plurality of water jets 202 can be uniform in the circumferential direction of the water jetting unit 20 The interval distribution means that the included angles between adjacent water spray openings 202 and the center of the water throwing member 20 are equal. At the same time, the included angles of the water outlet directions between adjacent water spray ports 202 may be equal.

A plurality of water spouts 202 make the water jetting member 20 form a multi-directional water outlet structure, and the specific angle and arrangement between adjacent water spouts 202 depend on the number of water spouts 202, which is not specified in this embodiment. Limitation, the following will illustrate with several specific examples.

When there are two water spouts 202, the water jetting member 20 is a two-way water outlet structure, and the water outlet directions of the two water spouts 202 are parallel to each other and in opposite directions, that is, the angle between the water outlet directions of the two water spouts 202 is 180°. °.

When there are three water spouts 202, the water jetting member 20 has a three-way water outlet structure, and the angle between the water outlet directions between the three water spouts 202 is 120°.

When there are four water spouts 202, the water jetting member 20 has a four-way water outlet structure, and the included angle between the water outlet directions between two adjacent water spouts 202 is 90° in the four water spouts.

Of course, other numbers of water spouts 202 can also be arranged in the peripheral direction of the water throwing member 20 , which will not be repeated here.

It should be noted that the shape of the water spray port 202 can be circular, square or other regular polygons, and the specific size of the water spray port 202 can be selected according to the size of the actual water spray flow. The specific shape and size of 202 are not limited.

In addition, except for the water spraying channel, the remaining part of the water thrower 20 can be a hollow structure, thereby reducing the overall weight of the water thrower 20 and making it easier to rotate under the force of the water flow.

Since the water inlet 201 of the water spray channel is located at the center of the water-spinning member 20, and there are multiple water spray ports 202, there can be a plurality of independent branch flow channels 203 for water supply from the water inlet 201 to each water spray port 202. Circulation, that is, the water spray channel can include a plurality of branch flow channels 203, and the extension direction of the branch flow channels 203 determines the water outlet direction of the water spray port 202 and the force direction of the sprayed water flow on the water throwing member 20. The flow direction in the flow channel 203 is the direction indicated by the arrow in FIG. 5 , and the water thrower 20 rotates in the X direction as shown in FIG. 5 , which will be described in detail below.

Wherein, the branch flow channel 203 can be arc-shaped, and can also be composed of a plurality of extension sections, so that the flow direction of the water flow from the water inlet 201 to the water spray port 202 can be changed, so that the reaction force of the water flow can make the water throwing member 20 generate torque.

In the first optional mode, the branch channel 203 may include a first extension section and a second extension section, the first end of the first extension section communicates with the water inlet 201, and the second end of the first extension section communicates with the second extension section. The first end of the section communicates, the second end of the second extension section communicates with the water spout 202, and the extension direction of the first extension section and the second extension section has an included angle, so that the water flows from the water spout along the second extension section. When the 202 is ejected, it can continuously generate a rotational moment to the water throwing member 20 .

After the water flow enters the branch channel 203 , it first passes through the first extension section, and then flows from the first extension section to the second extension section. The extension direction of the second extension section is consistent with the water outlet direction of the water spray port 202 . The transition between the first extension section and the second extension section can be smooth, so as to ensure smooth water flow and reduce impact.

In the second optional mode, the branch flow channel 203 can be an arc-shaped flow channel, and the protruding direction of the arc-shaped flow channel is away from the water outlet direction of the water spray port 202. In this way, the branch flow channel 203 can be changed to have a water outlet 201 The direction of the water flow to the water spray port 202 continues to generate a rotational moment on the water throwing member.

Optionally, each branch flow channel 203 can surround the center of the water rejection member 20, that is, it can be symmetrically arranged around the water inlet 201. A diversion plate or a diversion column is provided to guide the water flow into different branch flow channels 203 , which will be described with specific examples below.

Please refer to FIG. 5 , for example, when there are two water spouts 202, there are two branch flow channels 203, and the two branch flow channels 203 are symmetrical to the center of the water inlet 201, that is, two branch flow channels The first extension of 203 is collinear, and the direction of extension is opposite, while the second extension of the two branch channels 203 is parallel to each other, and the direction of extension is opposite, so that the sprayed water flow in the two water spouts 202 is opposite to the water throwing member. The direction of the acting force of 20 is opposite, and the direction of the formed rotational moment is the same, so that the water throwing member 20 rotates stably.

Optionally, the flow section of the branch channel 203 from the water inlet 201 to the water spray port 202 can gradually increase, that is, the size of the water outlet is larger than the size of the water inlet 201, so that when the water is sprayed, it can cover a wider space .

In addition, the water spray port 202 can be provided with a plurality of water guide plates 204 along the edge of the water jetting member 20, and the water guide plates 204 divide the water spray port 202 into a plurality of water spray holes, so that it can be seen that the water spray port 202 is sprayed. The water flow is scattered, which is more conducive to the formation of the water curtain.

The water guide plate 204 can be integrally formed with the water rejection member 20, and can also be assembled with the water rejection member 20 by clamping. Specific limits.
