Referring to fig. 1 and 2, an embodiment of the present disclosure provides a crossflow blower including an impeller 510, an impeller mounting structure 520, a first water delivery part 530, and a water outlet hole 532; both ends of the first water delivery part 530 are connected with the impeller mounting structure 520, and the first water delivery part 530 penetrates the impeller 510 along the axial direction; the water outlet hole 532 is provided in the first water feeding part 530 and is configured to discharge water to wash the impeller 510.

By adopting the cross-flow fan provided by the embodiment of the disclosure, the first water delivery part 530 is arranged in the impeller 510 of the cross-flow fan, and water in the first water delivery part 530 is sprayed to the impeller 510 through the water outlet hole 532, so that the impeller 510 is cleaned; the dust and dirt deposited on the impeller 510 can be effectively cleaned without detaching the cross-flow fan from the indoor unit of the air conditioner under the condition that the indoor unit of the air conditioner is not easily damaged.

Generally, crossflow blower includes a motor and impeller 510; the impeller 510 is in a long cylinder shape and is coaxially connected with the motor, and the impeller 510 is driven by the motor to rotate to form air flow.

Alternatively, the crossflow blower may be directly mounted to a mounting frame in the housing of the air treatment device, in which case the mounting structure 520 of the impeller may be a baffle plate disposed at both ends of the impeller 510. The barrier is driven by the motor to rotate with the impeller 510.

Herein, the cross-flow fan may be disposed in an indoor unit of an air conditioner, or may be disposed in other air processing equipment requiring setting of an air flow rate accelerated by the cross-flow fan. The air treatment device may be an air conditioner, a dehumidifier, a humidifier, an air purifier, etc., and is not particularly limited herein. In the embodiment of the present disclosure, the cross-flow fan is applied to an indoor unit of an air conditioner as an example, and in other embodiments of the present disclosure, the cross-flow fan may also be applied to other air processing devices.

Alternatively, the mounting structure 520 of the impeller may be provided with a fitting hole, which is a through hole provided on the mounting structure of one side of the impeller 510. The impeller mounting structure 520 and the first water delivery part 530 may be connected in a rotational manner. At this time, the first water delivery part 530 is relatively fixed with the casing of the air treatment device, and a bearing is arranged at the rotary connection position of the first water delivery part 530 and the mounting structure 520 of the impeller, and comprises an inner ring, a ball and an outer ring; the outer ring outer wall of the bearing is fixed with the inner wall of the assembly hole, the inner ring is rotatably connected with the outer ring through a plurality of balls, and the inner wall of the inner ring is fixedly connected with the outer wall of the first water delivery part 530. The mounting structure 520 of the impeller and the first water delivery part 530 interfere complementarily even if the crossflow blower is in an operating state, i.e., the impeller 510 and the mounting structure 520 of the impeller are in a rotating state.

Optionally, the first water delivery part 530 is disposed coaxially with the impeller 510. The first water delivery part 530 is just arranged at the axial center of the impeller 510, and at this time, no matter where the impeller 510 rotates, the same water outlet hole 532 of the first water delivery part 530 has the same distance from the impeller 510, so that it can be ensured that the impeller 510 is more uniformly cleaned by the first water delivery part 530.

Optionally, the first water delivery part 530 includes a first water pipe 531, and the water outlet hole 532 is disposed on a pipe wall of the first water pipe 531. The first water pipe 531 includes a first pipe section, and since the first water pipe 531 axially penetrates through the mounting structure 520 of the impeller, that is, the first water pipe 531 includes a portion of the water pipe disposed inside the impeller 510 and a portion of the water pipe extending out of the mounting structure 520 of the impeller and disposed outside the impeller 510. Here, a portion of the first water pipe 531 inside the impeller 510 is referred to as a first pipe section, and a portion of the first water pipe 531 outside the impeller 510 is referred to as a second pipe section.

Alternatively, the outlet hole 532 may be provided only to the first pipe section. Therefore, the water from the water outlet hole 532 can be sprayed to the impeller 510 from inside to outside, and the water falling on the variable surface of the impeller 510 can generate centrifugal force along with the rotation of the impeller 510, so that the water is continuously thrown out, and the cleaning effect on the impeller 510 is better. If the water pipe arranged at the water outlet hole 532 is arranged outside the impeller 510, water is discharged to the impeller 510; when the impeller 510 rotates, the effluent hardly contacts the surface of the impeller 510, and even if the effluent falls on the surface of the impeller 510, the water is rapidly dropped by the centrifugal force generated by the rotation of the impeller 510, and thus it is difficult to effectively clean the impeller 510. In the embodiment disclosed in the present application, the water outlet hole 532 is disposed in the first pipe section, so that the water accumulation phenomenon is not easily generated inside the impeller 510, and the water spray is not hindered from the centrifugal force generated by the rotation of the impeller 510 toward the impeller 510.

Optionally, the first water delivery part 530 further includes a spray head disposed at the water outlet hole 532 and configured to spray water back to the first water pipe 531. The shower nozzle can become many more tiny rivers with the play water homodisperse of apopore 532, makes first water delivery portion 530 more even to the water spray of impeller 510, and is better to impeller 510's cleaning performance.

Alternatively, the spray head may include a pressurizing means to make the water pressure sprayed from the spray head of the first water supplying part 530 greater and the impact on the surface of the impeller 510 greater, thereby improving the washing effect of the first water supplying part 530 on the impeller 510.

Optionally, the number of the water outlets 532 is multiple, and the water outlets 532 are evenly distributed in the first water delivery part 530 along the axial direction. In the same axial position, a plurality of water outlet holes 532 can also be uniformly distributed along the axial direction. Thus, the water outlet area and the water outlet amount of the first water supplying part 530 can be increased, so that the first water supplying part 530 has a better washing effect on the impeller 510. The dust and dirt deposited on the impeller 510 can be effectively cleaned without detaching the cross-flow fan from the indoor unit of the air conditioner under the condition that the indoor unit of the air conditioner is not easily damaged.

Optionally, the crossflow blower further comprises a water inlet portion 550 and a second water delivery portion 540; the second water feeding part 540 is provided to communicate the water feeding part 550 and the first water feeding part 530. The water inlet part 550 is provided to provide a source of water from the first water feeding part 530, where the water inlet part 550 may store a water tank, a tap water inlet pipe, or a manual water feeding opening, etc., and the water inlet part 550 may provide a source of water without being particularly limited.

Optionally, the second water delivery part 540 includes a second water pipe 541 and a water pump 542; one end of the second water pipe 541 is communicated with the water inlet part 550, and the other end of the second water pipe 541 is communicated with the first water delivery part 530; the water pump 542 is provided to the second water pipe 541, and is configured to pressurize water passing through the second water pipe 541. Therefore, the water conveying pressure of the second water pipe 541 to the first water pipe 531 is increased, the water flow pressure in the first water pipe 531 is increased, and the spraying pressure of the water from the water outlet hole 532 is increased, so that the impeller 510 of the cross flow fan is effectively washed, and the dust and dirt deposited on the impeller 510 are efficiently cleaned.

Optionally, a water pump 542 is disposed on the second water pipe 541 to pressurize the liquid conveyed in the water pipe, so that the water from the water outlet hole 532 has a cleaning effect on the impeller 510. Generally, pressurization is to convey water at a low end to a high end, and to drive the conveyance of liquid in a water pipe by driving of a water pump 542; in the present application, the water pump 542 is used for pressurizing the water conveyed in the second water pipe 541, so as to transfer the pressure to the first water pipe 531, and further increase the water outlet pressure of the water outlet hole 532 on the first water pipe 531, thereby improving the strength of the water outlet hole 532 for cleaning the impeller 510, and improving the cleaning effect of the impeller 510; the purpose of this pressurization is quite different from the purpose of delivering water from the low end to the high end.

Alternatively, the water inlet 550 may be an opening provided at one end of the second water pipe 541, and provide an inlet for manually adding water into the second water pipe 541.

Alternatively, the water inlet part 550 may include a water tank connected to one end of the second water pipe 541, the water inlet part 550 further includes a water pump 542, and the water pump 542 may be disposed at a connection of the water tank and the second water pipe 541; so that the water in the water tank is transferred to the second water pipe 541.

Alternatively, the water inlet part 550 may include a tap water inlet pipe to directly connect the second water pipe 541 with the tap water inlet pipe, so that it is more convenient to add water to the first water feeding part 530. The water inlet unit 550 further includes a water valve disposed at a connection position of the second water pipe 541 and the tap water inlet pipe, and can control whether to add water to the second water supply unit 540 and the first water supply unit 530 by controlling on/off of the water valve.

Alternatively, the water valve may be configured to control the connection and disconnection between the water inlet pipe and the second water pipe 541; the water valve can also be set to control the water quantity added into the second water pipe 541 by the water inlet pipe, and at this time, the water valve can be a valve body with an adjustable opening degree.
