Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The specific structure of the water-washing air device and the air conditioner indoor unit will be mainly described below. It should be noted that, in order to avoid repeating the description of the same feature multiple times, the features in the following embodiments may be applied to and organically combined with other embodiments, and it should be understood that the description has provided an embodiment in which the feature is applied to other embodiments.

The present utility model first provides a water-washable air device, fig. 1 is a schematic structural view of the water-washable air device according to an embodiment of the present utility model, fig. 2 and 3 are schematic structural sectional views of the water-washable air device according to an embodiment of the present utility model in different orientations, respectively, and fig. 4 is a schematic enlarged view of a portion a in fig. 3. Referring to fig. 1-4, a water-washed air device 10 may generally include a body 11 and a water curtain generating device 12.

The inside of the body 11 defines a washing air compartment 111, and the body 11 has an air inlet 112 and an air outlet 113 communicating with the washing air compartment 111. The water curtain generating device 12 is disposed in the air washing compartment 111, and is configured to form a water curtain on an airflow flow path between the air inlet 112 and the air outlet 113 by using water in the air washing compartment 111. The water curtain of the present utility model is a broad concept, and means a water state in which a sufficient and effective contact with an air stream can be performed. The specific form of the water curtain can be varied, for example, the water curtain includes but is not limited to mist, water vapor, water flow, and water curtains in a narrow sense, etc.

The water-washing air device 10 of the present utility model comprises a machine body 11 defining a water-washing air compartment 111 and a water curtain generating device 12 arranged in the water-washing air compartment 11, wherein the water curtain generating device 12 can form a water curtain on an airflow flowing path from an air inlet 112 to an air outlet 113 of the machine body 11 by utilizing water in the water-washing air compartment 111. When the air flows along the air flow path from the air inlet 112 to the air outlet 113 and passes through the water curtain, dust, particles and other impurities in the air flow are carried away by the water in the water curtain, and meanwhile, part of moisture in the water curtain can be carried away by the air flow, so that the air flow passing through the water curtain is purified and humidified.

In particular, the body 11 is provided on its inner wall for contact with the water curtain with a first buffer silencer 13. Thus, during the generation of the water curtain by the water curtain generating means 12, the water flow does not directly strike the inner wall of the body 11, but contacts the first buffering silencer 13 on the inner wall. The first buffering silencer 13 has buffering and silencing functions, and generates no obvious noise even if impacted by water flow, so that the water flow impact sound in the operation process of the water washing air device 10 is obviously weakened, the operation noise is reduced, and the use experience of a user is improved.

In some embodiments, the water curtain generating device 12 is configured to controllably rotate about a vertical axis of rotation to throw water within the wash air chamber 111 in a radial direction thereof to form a water curtain in a horizontal plane. In these embodiments, the first cushion muffler 13 is provided on the circumferential inner side wall of the body 11 at the same height as the water curtain.

It will be appreciated that when the water curtain generating device 12 rotates along the vertical rotation axis, the water in the air washing compartment 111 is thrown out along the radial direction, and when the speed of the water being thrown out is high enough, the gravity influence of the water can be ignored, and at this time, the water curtain formed by the water curtain generating device 12 is approximately in the same horizontal plane, that is, the water curtain has a certain height. The height of the water curtain is the height of the water flow which is thrown out. Therefore, the first buffering silencing piece 13 is arranged on the circumferential inner side wall of the machine body 11, which is the same height as the water curtain, so that the first buffering silencing piece 13 just receives the thrown water flow, and the phenomenon that the thrown water flow directly impacts the inner wall of the machine body 11 to generate larger noise is effectively avoided.

In some embodiments, the body 11 is further provided with a second buffering silencer 14 below the first buffering silencer 13 and opposite to the first buffering silencer 13 in the up-down direction. The top of the second buffer muffler 14 is higher than the water surface in the wash air chamber 111 to receive water dropped from the first buffer muffler 13 through the second buffer muffler 14.

When the amount of water hitting the first buffer silencer 13 increases, water drops from the first buffer silencer 13, and if the water drops directly into the water in the air washing compartment 111, significant water drop sound or water flowing sound is generated. Therefore, the second buffer silencer 14 is disposed below the first buffer silencer 13 and vertically opposite to the first buffer silencer 13, and the second buffer silencer 14 can receive the water drops and water flows dropped from the first buffer silencer 13, so as to prevent the water drops or water flows from directly falling into the water to generate obvious dripping sound or running sound, and effectively reduce dripping sound or running sound.

In some embodiments, the materials of the first buffer muffler 13 and the second buffer muffler 14 may be the same or different. Preferably, the first and second cushion silencers 13 and 14 may each be a sponge. The sponge is soft in material and strong in water absorption capacity, and can play a better silencing role.

It will be appreciated that when the water curtain generating device 12 is rotated about its vertical axis of rotation, water within the wash air chamber 111 is thrown in all directions along its radial direction. In order to more thoroughly eliminate noise, the first buffering noise damper 13 is preferably in a ring shape matching the shape of the inner wall of the body 11 to receive water flow thrown from various directions in the radial direction of the air washing compartment 111. Accordingly, the second cushion muffler 14 may also be ring-shaped with the same or substantially the same shape.

In some embodiments, the body 11 includes a lower housing 114 and an upper housing 115 coupled to an upper portion of the lower housing 114, the upper housing 115 having a sleeve 1151, the sleeve 1151 being inserted into the lower housing 114 from top to bottom, an air flow channel 116 being formed between an outer peripheral wall of the sleeve 1151 and an inner peripheral wall of the lower housing 114, a bottom of the sleeve 1151 being spaced from a bottom wall of the lower housing 114 such that the sleeve 1151 communicates with the air flow channel 116.

Specifically, the bottom port of sleeve 1151 and the bottom port of airflow channel 116 are both in communication with the interior space of lower housing 114, and thus sleeve 1151 may be in indirect communication with airflow channel 116 through the interior communication of lower housing 114.

Further, the air inlet 112 communicates with the sleeve 1151 and the air outlet 113 communicates with the air flow channel 116. The airflow entering from the air inlet 112 may sequentially flow through the sleeve 1151 and the airflow channel 116 before flowing to the air outlet 113.

Further, the water curtain generating device 12 is configured to form a water curtain at a lower portion inside the sleeve 1151, and the first buffering noise damper 13 is provided at an inner peripheral wall of the lower portion of the sleeve 1151, thereby preventing water flow for forming the water curtain from directly striking the inner peripheral wall of the sleeve 1151. When the air flows through the lower part of the sleeve 1151, the air passes through the water curtain, thus being purified and humidified, and the purified and humidified air flows to the air flow channel 116 and finally flows to the air outlet 113.

Specifically, in the illustrated embodiment of the present utility model, the water curtain generating device 12 forms a water curtain at the bottom of the sleeve 1151, and the first buffering noise damper 13 is provided at the inner circumferential wall of the bottom end of the sleeve 1151.

In some embodiments, the sum of the thickness of the lower portion of sleeve 1151 and the thickness of first cushion muffler 13 in the radial direction of sleeve 1151 is less than the thickness of second cushion muffler 14 in the radial direction of sleeve 1151, such that the projection of the lower portion of sleeve 1151 and first cushion muffler 13 in the horizontal plane is in the projection of second cushion muffler 14 in the horizontal plane.

Thus, neither the water drops or the water flows dropped from the first buffer muffler 13 nor the water drops or the water flows dropped from the inner peripheral wall and the outer peripheral wall of the sleeve 1151 are received by the second buffer muffler 14, and the water drops or the water flows are not directly dropped or dropped onto the water surface, thereby eliminating the drop noise more thoroughly.

In some embodiments, the air intake 112 may be open on the upper housing 115 and communicate with the top of the sleeve 1151. The air outlet 113 may be formed in the upper housing 115, and an air outlet channel 117 for communicating the air outlet 113 with the air flow channel 116 is defined in the upper housing 115.

Further, the connection between the air inlet 112 and the sleeve 1151, and the connection between the air outlet 117 and the air flow 116 may be provided with filtering devices such as a filter screen, so as to further purify the air flow.

In some embodiments, the water-washed air device 10 further includes a fan 15, the fan 15 configured to controllably rotate to induce an airflow from the air intake 112 toward the air outlet 113.

The fan 15 is arranged in the water washing air device 10, and when the fan 15 rotates, air flow can be promoted to flow from the air inlet 112 to the air outlet 113, so that the air flow can be purified through the water curtain generated by the water curtain generating device 12, and the air flow purification and humidification functions can be actively and independently realized.

Further, the air washer 10 also includes a drive device 16, the drive device 16 being configured to controllably drive the water curtain generating device 12 and the fan 15 in rotation. That is, the water curtain generating device 12 and the fan 15 share one driving device 16, so that the design is ingenious, the number of the driving devices 16 is reduced, the structure of the water washing air device 10 is simplified, and the cost is reduced.

Specifically, the driving device 16 can drive the water curtain generating device 12 and the fan 15 to synchronously rotate, so that the structural design difficulty is reduced.

In some embodiments, the top of the water curtain generator 12 extends upwardly into the sleeve 1151, and the bottom of the water curtain generator 12 is inserted into the water in the wash air chamber 111 so as to draw water upwardly through the bottom of the water curtain generator 12 as it rotates about the vertical axis and to spin the drawn water out around through the top thereof, thereby forming a water curtain in the sleeve 1151.

Further, a fan 15 is provided in the sleeve 1151 and is connected above the water curtain generating device 12. The fan 15 draws in air from the air inlet 112 and forces it to flow toward the curtain of water produced by the curtain generating device 12 as it rotates.

Further, the driving device 16 includes a motor 161 disposed outside the bottom wall of the lower housing 114, and a rotation output shaft 162 of the motor 161 is inserted into the lower housing 114 and fixedly connected to the water curtain generating device 12 and the fan 15. Thus, when the motor 161 rotates, the rotation can be transmitted to the water curtain generating device 12 and the fan 15 through the rotation output shaft 162 thereof, thereby causing the water curtain generating device 12 and the fan 15 to rotate synchronously.

Specifically, the rotation output shaft 162 of the motor 161 can be connected with the water curtain generating device 12 and the fan 15 in a form-fitting manner, and the connection manner is simple and reliable. Further, the end of the rotation output shaft 162 of the motor 161 may be further provided with threads so as to stably connect the fan 15 to the rotation output shaft 162 by a nut or the like.

In some embodiments, a mounting post 1141 protruding upward from an inner bottom wall of the lower housing 114 is provided at a bottom of the lower housing 114, and the inside of the mounting post 1141 is penetrated up and down to pass through the rotation output shaft 162 of the power supply 161 from the bottom to the top and out from an upper end of the mounting post 1141 to be connected to the water curtain generating device 12 and the fan 15.

The installation of the mounting post 1141 not only facilitates the connection of the motor 161 with the water curtain generating device 12 and the fan 15, but also effectively isolates the rotation output shaft 162 of the motor 161 from the water in the air washing compartment 111, thereby achieving a better safety performance. In addition, the mounting post 1141 can also support the water curtain generating device 12 and the fan 15, the water curtain generating device 12 can be directly mounted on the mounting post 1141, and the fan 15 is mounted above the water curtain generating device 12 without providing other mounting support parts, so that the structure is further simplified.

Further, the interior of the mounting post 1141 is provided with a radially inwardly extending annular seal 1142, the annular seal 1142 being adapted to be in pressing contact with the rotary output shaft 162 of the motor 161 to form a seal. Thus, water can be effectively prevented from entering the mounting post 1141 from the assembly gap between the mounting post 1141 and the water curtain generating device 12, and further contacting the motor 161 to generate potential safety hazards.

Specifically, the annular seal 1142 may be soft silicone, rubber, or the like.

In some embodiments, the water wash air device 10 further includes a water tank 18, the water tank 18 being in communication with the wash air compartment 111 to replenish water within the wash air compartment 111.
