The air treatment device 100 for an air conditioner indoor unit 800 and the air conditioner indoor unit 800 according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 14 .

As shown in Figures 1 to 14, according to the air treatment device 100 for the air-conditioning indoor unit 800 according to an embodiment of the present invention, the air-conditioning indoor unit 800 has a heat exchange air duct (not shown in the figures), so that indoor air can enter the heat exchange air duct for heat exchange, thereby realizing the cooling or heating function of the air conditioner.

As shown in Fig. 1 to Fig. 6, the air treatment device 100 comprises a housing 10, a guide fan 20, a water treatment component 30 and a water container 40, wherein the guide fan 20, the water treatment component 30 and the water container 40 are respectively arranged in the housing 10, and an indoor air inlet 110 and an indoor air outlet 120 are arranged on the housing 10, and an air treatment duct isolated from the heat exchange duct is arranged in the housing 10, whereby, under the action of the guide fan 20, indoor air can be introduced into the air treatment duct from the indoor air inlet 110, and processed in the air treatment duct, and the processed indoor air flows out from the indoor air outlet 120. Moreover, by isolating the heat exchange duct from the air treatment duct, mutual interference between the air flow in the air treatment duct and the heat exchange channel can be prevented.

The water treatment component 30 is constructed to guide the water in the water container 40 to the air treatment duct so that the water molecules contact the air in the air treatment duct. It should be noted that the water treatment component 30 can guide the water in the water container 40 into the air treatment duct, so that a large number of moving small droplets are distributed in the air treatment duct or a water curtain, a water film, etc. are formed in the air treatment duct. When the indoor air flows in the air treatment duct, the air collides with the water vapor, thereby, the moving water vapor in the air treatment duct can remove the dust entrained in the air, and can increase the humidity of the air. That is, when the air flows in the air treatment duct, it is "washed with water", so that the airflow flowing out of the indoor air outlet 120 is fresher, and the indoor air quality is improved.

According to the air treatment device 100 of the indoor unit 800 of the air conditioner of the embodiment of the present invention, by providing the guide fan 20, the water treatment component 30 and the water container 40, the guide fan 20 can introduce the indoor air into the air treatment duct, and the water treatment component 30 can guide the water in the water container 40 into the air treatment duct. When the indoor air flows in the air treatment duct, the water vapor in the air treatment duct can remove the dust particles in the air and increase the humidity of the air. Thus, the indoor air is fresher and the indoor air quality is improved.

In some embodiments of the present invention, as shown in FIG9 and FIG12, the air treatment device 100 may further include a purification unit 50, and the purification unit 50 is located upstream of the water treatment component 30 in the air flow direction (such as the air flow direction shown by the arrows in FIG9 and FIG12). Thus, the purification unit 50 can filter and purify the indoor air to remove large particles of impurities in the air. In combination with FIG1-FIG6, FIG9 and FIG12, the purification unit 50 can be arranged at the indoor air inlet 110, and the purification unit 50 can be a filter membrane (such as a HEPA membrane, etc.), so that the air flowing into the air treatment device 100 can be preliminarily filtered to reduce the impurity content of the air entering the air treatment device 100.

According to some embodiments of the present invention, the air treatment device 100 may further include a temperature adjustment unit (not shown in the figure), which is located in the housing 10 and upstream of the water treatment component 30 in the air flow direction, so that the indoor air temperature can be adjusted to meet the customer's usage requirements. It is understandable that when the indoor temperature is low, the temperature adjustment unit can heat the indoor gas, and the indoor air after heating is purified again by the water treatment component 30, thereby improving the temperature and cleanliness of the indoor air. When the indoor temperature is high, the temperature adjustment unit can cool the indoor gas, and the indoor air after cooling is purified again by the water treatment component 30. In this way, the autonomous adjustment of the indoor air temperature can be achieved, and the practicality of the air treatment device 100 can be improved.

Optionally, the temperature adjustment unit may use a semiconductor refrigeration element and utilize the Peltier effect to achieve both heating and cooling functions. Of course, it is understandable that the temperature adjustment unit may also have only a heating function or a cooling function.

In some embodiments of the present invention, as shown in FIG12 , the air treatment device 100 may further include a humidifying unit 70, which is located downstream of the water treatment component 30 in the air flow direction. Thus, the air treated by the water treatment component 30 can be further filtered and humidified by the humidifying unit 70, so that the airflow flowing out of the indoor air outlet 120 is more fresh, further improving the indoor air quality. For example, the indoor air is relatively dry in winter, which is easy to cause discomfort to the user's body. The humidifying unit 70 is arranged downstream of the water treatment component 30, and the indoor air enters the humidifying unit 70 after being purified by the water treatment component 30. The humidifying unit 70 can further increase the humidity of the indoor air, thereby improving the comfort of the airflow flowing out of the indoor air outlet 120. Optionally, the humidifying unit 70 can be automatically controlled, and the user can adjust the working state of the humidifying unit 70 according to the actual indoor conditions, thereby realizing automatic adjustment of the indoor humidity.

Furthermore, the humidifying unit 70 may include a humidifying membrane (not shown in the figure), so as to facilitate the adjustment of air humidity. For example, the humidifying unit 70 may include a water sprayer and a humidifying membrane, the water sprayer is arranged on the upper part of the humidifying membrane, and the humidifying membrane is provided with a plurality of air holes penetrating the humidifying membrane in the thickness direction, and the water sprayer can continuously spray water on the humidifying membrane, so that a stable water film can be formed on the air holes. After the indoor air is treated by the water treatment element 30, the indoor air enters the humidifying unit 70 again and is discharged from the air holes on the humidifying unit. When the indoor air passes through the water film, the water molecules in the water film can be adsorbed on the gas molecules in the air, so as to increase the humidity of the indoor air.

In some embodiments of the present invention, the water treatment component 30 is configured to spray water toward the air treatment duct. As shown in FIGS. 1-3 , the water treatment component 30 can spray water in the water container 40 toward the air treatment duct. Thus, when the air flows in the air treatment duct, it can collide with the water vapor in the air treatment channel, so that the water vapor can remove dust from the air and increase the humidity of the air. The air after dust removal and humidification treatment flows out of the air treatment device 100 from the indoor air outlet 120, thereby improving the indoor air quality.

According to an embodiment of the present invention, the air conditioner indoor unit 800 includes: an indoor heat exchange part and an air treatment device 100, the indoor heat exchange part includes an outer shell 810, an indoor heat exchanger 830 and an indoor fan 840, the indoor heat exchanger 830 and the indoor fan 840 are arranged in the outer shell 810, thereby, air can enter the indoor heat exchange part under the action of the indoor fan 840 and exchange heat with the indoor heat exchanger 830, thereby achieving the cooling or heating effect of the air conditioner indoor unit 800.

The air handling device 100 is arranged on the indoor heat exchange part. It should be noted that the air handling device 100 can be arranged inside the shell 810, and the shell 810 defines the shell 10 of the air handling device; the air handling device 100 can also be arranged outside the shell 810, and the shell 10 of the air handling device 100 is fixedly connected to the shell 810 of the indoor heat exchange part.

In some examples of the present invention, as shown in FIG9 and FIG12, a first space S1 and a second space S2 are provided in the housing 810, and the first space S1 has an air inlet 811 and an air outlet 812, so that indoor air can enter the first space S1 from the air inlet 811, and after being processed in the first space S1, flow out of the first space S1 from the air outlet 812. The housing 810 is provided with an indoor air inlet 821 and an indoor air outlet 822 that are connected to the second space S2.

As shown in Figures 9 and 12, the indoor heat exchanger 830 and the indoor fan 840 are respectively arranged in the first space S1, so that the indoor fan 840 can drive the indoor air to circulate in the first space S1 and the indoor room, and the indoor air entering the first space S1 can pass through the indoor heat exchanger 830 for heat exchange. After the indoor air in the first space S1 exchanges heat with the indoor heat exchanger 830, it flows out of the first space S1 from the air outlet 812, thereby completing the cooling or heating effect of the air conditioner.

The air treatment device 100 is arranged in the second space S2, which facilitates the layout of the internal structure of the air-conditioning indoor unit 800, prevents the internal structure of the first space S1 from interfering with the internal structure of the second space S2, and prevents the airflow in the first space S1 from interfering with the airflow in the second space S2, thereby improving the operating stability and efficiency of the air-conditioning indoor unit 800.

According to the air conditioner indoor unit 800 of the embodiment of the present invention, by providing the air treatment device 100 in the air conditioner indoor unit 800, the water treatment component 30 can guide the water in the water container 40 to the air treatment duct. When the indoor air flows in the air treatment duct, a large amount of water vapor in the air treatment duct can remove dust particles in the air and increase the humidity of the air. Thus, the indoor air is fresher and the indoor air quality is improved.

In some embodiments of the present invention, as shown in Figures 13 and 14, the air conditioner indoor unit 800 is a wall-mounted unit. It can be understood that the wall-mounted unit is small in size and occupies a small space. By arranging the air treatment device 100 in the wall-mounted unit, the quality of the air flowing out of the wall-mounted unit can be improved, making the indoor air fresher, which is beneficial to the health of the user and improving the overall performance of the air conditioner indoor unit 800.

Optionally, the second space S2 may be located at the lower portion of the housing 810, and the indoor air outlet 822 may be located on the bottom wall of the housing 810. Thus, the airflow flowing out of the indoor air outlet 822 may be prevented from directly blowing on the user, thereby improving the comfort of the air outlet of the air conditioner indoor unit 800. Specifically, the second space S2 is disposed at the lower portion of the housing 810, and the air treatment device 100 in the second space S2 may guide the indoor air from the bottom of the air conditioner indoor unit 800 to the air treatment device 100 through the guide fan 20, and the indoor air is purified in the air treatment device 100, and after purification, the indoor air is discharged from the indoor air outlet 822 on the bottom wall of the housing 810.

According to some embodiments of the present invention, the air inlet 811 may be located in the middle of the front surface of the housing 810, and there are two air outlets 812 located on both sides of the air inlet 811. Specifically, when the air conditioner indoor unit 800 is working, indoor air enters the air conditioner indoor unit 800 from the air inlet 811 on the front surface of the housing 810, and the indoor heat exchanger 830 completes the heat exchange of the indoor air, and then the air is discharged from the air outlets 812 on both sides of the housing 810. By arranging the air outlets 812 on both sides of the housing 810, the air conditioner indoor unit 800 can blow air in two directions, thereby improving the speed of adjusting the indoor temperature and improving the uniformity of the air supply of the air conditioner indoor unit 800, thereby improving the user experience of the air conditioner indoor unit 800.

In some embodiments of the present invention, as shown in FIGS. 7 to 12 , the air conditioner indoor unit 800 may be a vertical air conditioner. It is understandable that the vertical air conditioner is easy to move, so that the position of the air conditioner indoor unit 800 can be adjusted. Further, the second space S2 may be located at the lower part of the housing 810, and the indoor wind outlet 822 may be located at the middle part of the housing 810. Thus, the appearance of the air conditioner indoor unit 800 may be improved, and the indoor air may be blown into the room from the indoor wind outlet 822 at the middle part of the housing 810 after being purified by the air treatment device 100, so as to facilitate the indoor air circulation.

The air treatment device 100 for the air conditioner indoor unit 800 according to the embodiment of the present invention will be described in detail with reference to five specific embodiments with reference to FIGS. 1 to 6 .

Embodiment 1:

As shown in FIG. 1 , the air treatment device 100 includes a housing 10 , a induced draft fan 20 , a water treatment component 30 , and a water container 40 .

The guide fan 20, the water treatment component 30 and the water container 40 are respectively arranged in the housing 10, and the housing 10 is provided with an indoor air inlet 110 and an indoor air outlet 120. The housing 10 is provided with an air treatment duct, and at least a part of the air treatment duct extends horizontally. The indoor air inlet 110 is provided on the left and right vertical side walls of the housing 10, and the indoor air outlet 120 is located on the top wall of the housing 10. The air enters the air treatment duct from the indoor air inlet 110, flows horizontally in the air treatment duct, then flows vertically upward, and finally flows out from the indoor air outlet 120.

The water treatment part 30 includes: a water application part 31a and a water pumping part 32a. The water application part 31a is located directly above the water container 40. The water container 40 is connected to the water application part 31a to supply water to the water application part 31a. The water application part 31a is formed in a horizontally extending flat plate shape. A plurality of water spraying ports (not shown in the figure) are provided on the bottom wall of the water application part 31a. The side wall of the water application part 31a is provided with a water inlet connected to the water container 40. Thus, the water in the water container 40 can enter the water application part 31a from the inlet and evenly spray water droplets to the air treatment duct. In the air treatment duct, the air and the water droplets flow in opposite directions, thereby improving the cleaning, dust removal and humidification effects of the water droplets on the air.

The water pumping member 32a is located in the water container 40, and the water pumping member 32a is connected to the water applying member 31a to pump the water in the water container 40 into the water applying member 31a. The working efficiency of the water pumping member 32a can be adjusted to control the flow rate of water entering the water applying member 31a. For example, when the indoor air is relatively dry, the power of the water pumping member 32a can be increased, so that more water droplets are sprayed from the water applying member 31a, which plays a certain humidification role while removing dust from the air flow. When the indoor air is relatively humid, the power of the water pumping member 32a can be reduced, thereby reducing the water droplets sprayed from the water applying member 31a, so that the water vapor content in the air flow blown out by the guide fan 20 is reduced.

Therefore, water is sprayed into the air treatment duct through the water applying member 31a. When the air flows in the air treatment duct, the air collides with water vapor. The water vapor can remove dust in the air and increase the humidity of the air. As a result, the cleanliness and humidity of the air treated by the air treatment device are improved, thereby improving the indoor air quality.

Embodiment 2:

As shown in Figure 2, different from Example 1, in this embodiment, the indoor air inlet 110 of the air treatment duct is located on the vertical wall on the left side of the shell 10, and the indoor air outlet 120 is located on the vertical wall on the right side of the shell 10, and is arranged opposite to the indoor air inlet 110. The air enters the air treatment duct from the indoor air inlet 110, flows horizontally along the air treatment duct, and finally flows out from the indoor air outlet 120.

Therefore, when the air flows in the air handling duct, the flow direction of the air is roughly perpendicular to the direction in which the water droplets fall, so that the dust in the air can be washed away by the water droplets and the humidity of the air can be increased, thereby improving the indoor air quality.

Embodiment three:

As shown in FIG3 , different from the first embodiment, in this embodiment, at least a portion of the air treatment duct extends longitudinally, and the water application member 31a sprays water downwardly toward the longitudinally extending portion of the air treatment duct. The guide fan 20 is located downstream of the water treatment member 30, and the guide fan 20 is located above the water treatment member 30, so that water flows downward from the water application member 31a under its own gravity and sprays to the longitudinally extending portion of the air treatment duct, while the air has a low density and flows from bottom to top in the longitudinally extending portion of the air treatment duct under the drive of the guide fan 20, so that the air and water form natural convection, so that the air and water can be fully in contact, ensuring the air purification effect, and the structure is simple and easy to implement.

As shown in FIG3 , the water treatment component 30 includes a porous sieve plate 311, a water channel 312 and a water pumping component 32a. The porous sieve plate 311 is provided with a plurality of through holes. The lower end of the water channel 312 is connected to the water container 40 and the upper end of the water channel 312 is located above the porous sieve plate 311 to supply water toward the porous sieve plate 311. As shown in FIG3 , the porous sieve plate 311 is located in the air treatment duct, and the indoor air outlet 120 of the air treatment duct is located above the porous sieve plate 311, so that the air in the air treatment duct needs to pass through the porous sieve plate 311 before flowing to the indoor air outlet 120 of the air treatment duct. A water film is formed on the porous sieve plate 311, so that when the air passes through the through holes of the porous sieve plate 311, bubbles are generated due to the obstruction of the water film. The bursting of the bubbles can increase the contact area between the air and the water, so that more fine particles in the air are attached to the water, thereby improving the air purification effect.

It is understandable that the shape, size, number and distribution of the through holes can be set according to actual needs to better meet practical applications. Of course, the porous screen plate 311 can also be replaced by a porous structure such as a wire mesh, but is not limited thereto.

The water pumping member 32a is connected to the water applying member 31a to pump the water in the water container 40 toward the water applying member 31a. As shown in FIG3 , an opening is formed directly above the water container 40, and the water applying member 31a can be arranged opposite to the opening. The water pumping member 32a is located in the water container 40 to pump the water in the water container 40 from bottom to top toward the water applying member 31a, and the water applying member 31a sprinkles the water from top to bottom toward the longitudinal extension of the air treatment duct to purify the air. After purification, the water returns downward to the water container 40 under the action of its own gravity, realizing the recycling of the water in the water container 40 to save water. Among them, the water pumping member 32a can be selected as a water pump, but is not limited to this.

The water applying member 31 a is formed in a horizontally extending flat plate shape, a plurality of water spraying ports are provided on the bottom wall of the water applying member 31 a , and a water inlet connected to the water container 40 is provided on the side wall of the water applying member 31 a .

It is understandable that the number of water inlets can be set to one or more according to actual needs, and the shape, size, number and arrangement of the multiple water spray outlets can be set according to actual needs to better meet practical applications.

Therefore, by providing a water applying member 31a and allowing the water applying member 31a to apply water to the longitudinal extension portion of the air treatment duct, the indoor air can come into contact with water to purify the indoor air and protect the health of the user; at the same time, since the flow area of the air flow path remains unchanged, the purified air volume of the air treatment device 100 is guaranteed, so that when the air treatment device 100 is applied to the air-conditioning indoor unit 800, the working efficiency of the air-conditioning indoor unit 800 can be improved.

Embodiment 4:

As shown in Figure 4, different from the first embodiment, in this embodiment, the water treatment component 30 includes: a wet membrane 33a, a water applying component 31a, a water pumping component 32a and a water container 40, the water container 40 is connected to the water applying component 31a to supply water to the water applying component 31a, the water applying component 31a applies water toward the wet membrane 33a, and the wet membrane 33a is located in the air treatment duct.

Part of the air flow of the air conditioner indoor unit 800 can flow into the air treatment device 100 from the indoor air inlet 110, wherein the air flow in the air treatment duct can flow through the wet film 33a, the water container 40 is connected and communicated with the water application member 31a, the water in the water container 40 can flow to the water application member 31a and spray water to the wet film 33a through the water application member 31a, and the air flow flowing through the wet film 33a can interact with the water flow on the wet film 33a. The air can pass through the wet film 33a, and large particles of dust can be blocked and flow down with the water flow sprayed to the wet film 33a by the water application member 31a, so that the air flow passing through can be filtered, dust-removed and humidified, and the air flow after passing through the wet film 33a can flow out from the indoor air outlet 120 under the action of the guide fan 20.

As shown in FIG4 , the water applying member 31a is arranged above the wet film 33a to spray water toward the wet film 33a, and the water pumping member 32a is connected to the water applying member 31a to pump water in the water container 40 toward the water applying member 31a. The water container 40 needs to store water, and the volume and weight are large. The water container 40 is arranged below the water applying member 31a, which is conducive to the arrangement of the water container 40. In addition, the water pumping member 32a in the water container 40 is used to pump water from the water container 40 with low gravitational potential energy to the water applying member 31a with high gravitational potential energy, and the flow rate of the water flow can also be controlled to avoid a large amount of water from forming a large pressure on the water applying member 31a. It can be understood that the water sprayed from the water applying member 31a is sprayed toward the upper end of the wet film 33a, and under the action of the gravity of the water flow itself, it can flow to the middle section and the lower end of the wet film 33a. Thus, the water sprayed by the water application component 31a can flow through the entire wet film 33a, thereby improving the effect of the wet film 33a, and reducing the spray force of the water application component 31a, thereby reducing the additional power of the water treatment component 30, thereby improving the performance of the air conditioning indoor unit 800.

The wet film 33a is formed in an annular shape, the indoor air inlet 110 of the air handling duct is located at the side of the wet film 33a, and the indoor air outlet 120 of the air handling duct is located above the internal space of the wet film 33a. It can be understood that the overall shape of the wet film 33a is cylindrical, and the air flow in the air handling duct can flow in from the outer peripheral wall of the wet film 33a, and flow out from the inner peripheral wall of the wet film 33a and flow upward (up and down direction as shown in Figure 4) under the action of external force. Thus, the air flow can pass through the wet film 33a, and dust can be combined with water droplets, so that the separation of air and dust can be achieved, and a small amount of water droplets with dust passing through the wet film 33a can also fall downward under the action of their own gravity, so that the second filtration of dust can be achieved.

Therefore, by setting a water treatment component 30 in the air-conditioning indoor unit 800, the air flow in the air treatment duct can be in close contact with the water on the wet film 33a when passing through the wet film 33a, and the inertial collision of water droplets and dust particles can be used to dissolve the dust particles, liquid and gaseous pollutants in the air into water, thereby isolating the dust to a certain extent. Moreover, the air passing through the wet film 33a can carry part of the water vapor and flow out from the indoor air outlet 120 under the action of the guide fan 20, thereby increasing the humidity of the outlet air flow. Therefore, the function of the air-conditioning indoor unit 800 can be expanded, the performance of the air-conditioning indoor unit 800 can be improved, and the user's comfort can be improved.

Embodiment five:

As shown in FIG5 , different from the first embodiment, in this embodiment, the water container 40 is formed as a water tank 40a, and the water treatment component 30 is a water-splitting component 34a, which is rotatably arranged in the housing 10. When the water-splitting component 34a rotates in the housing 10, the water in the water tank 40a can be thrown into the air treatment duct, so that a large number of moving small droplets are distributed in the air treatment duct to form a water curtain. When the indoor air flows in the air treatment duct, the air collides with the small droplets in the process of passing through the water curtain, thereby, the moving small droplets in the air treatment duct can remove the dust entrained in the air, and can also increase the humidity of the air. Therefore, when the air flows in the air treatment duct, it is "washed with water", so that the airflow flowing out of the indoor air outlet 120 is more fresh, and the indoor air quality is improved.

As shown in FIG5 , the rotation axis of the water-spraying member 34a extends horizontally, and a portion of the water-spraying member 34a extends into the water tank 40a. The water-spraying member 34a can rotate in a vertical plane. Thus, when the water-spraying member 34a rotates, the water in the water tank 40a can be thrown into the air handling duct to remove dust and humidify the air in the air handling duct. Moreover, the water-spraying member 34a is partially extended into the water tank 40a, which can reduce the resistance of the water-spraying member 34a when it rotates, thereby saving energy and reducing consumption.

As shown in Fig. 5, there are multiple water-spraying members 34a and they are spaced apart in a direction parallel to the rotation axis of the water-spraying member 34a. Thus, the number of small liquid droplets moving in the air handling duct can be increased, and the probability of small liquid droplets colliding with air can be increased, thereby further improving the dust removal and humidification effects of the air handling device 100.

The motor shaft of the guide fan 20 is connected to the water pumping member 34a to drive the water pumping member 34a to rotate. Therefore, the guide fan 20 and the water pumping member 34a can share a driving motor, saving production costs, facilitating the assembly of the air treatment device 100, and making the structure of the air treatment device 100 simpler and more compact.

The water-spinning member 34a is provided with a through hole (not shown in the figure), and the through hole penetrates the water-spinning member 34a in the thickness direction of the water-spinning member 34a. It can be understood that by providing the through hole on the water-spinning member 34a, when the water-spinning member 34a rotates, the through hole on the water-spinning member 34a that extends into the water tank 40a can be filled with water, and as the water-spinning member 34a rotates, the water in the through hole can be thrown into the air handling duct, thereby increasing the water vapor content in the air handling duct. Moreover, when the rotation speed of the water-spinning member 34a is slow, a water film can be formed at the through hole, and when the air passes through the water film, dust in the air can be removed and the humidity of the air can be increased.

Thus, by providing the guide fan 20 and the water treatment member 30, the guide fan 20 can introduce indoor air into the air treatment duct, and the rotating water-spraying member 34a can guide the water in the water tank 40a into the air treatment duct. When the indoor air flows in the air treatment duct, a large number of small droplets moving in the air treatment duct can remove dust particles in the air and increase the humidity of the air. Thus, the indoor air is fresher and the indoor air quality is improved.

Embodiment six:

As shown in FIG6 , different from the first embodiment, in this embodiment, the water treatment component 30 is a rotatable centrifugal water-repelling component 35a, and a portion of the centrifugal water-repelling component 35a extends into the water in the water container 40 to form a water curtain 355 in the air treatment duct by centrifugal action. The water curtain 355 can purify the indoor air entering the water treatment component 30. As shown in FIG6 , the lower end of the centrifugal water-repelling component 35a is below the liquid level of the water container 40, and the water in the water container 40 can be drawn into the centrifugal water-repelling component 35a. The centrifugal water-repelling component 35a rotates by itself, and due to the action of centrifugal force, the water forms a layer of water curtain 355 in the air treatment duct.

The guide fan 20 can guide the indoor air to circulate in the air handling duct, and the indoor air passes through the water curtain 355, and then the indoor air is discharged from the indoor air outlet 120. When the indoor air passes through the water curtain 355, the water molecules in the water curtain 355 can absorb the dust and dust particles in the indoor air and make them melt into the water, so as to purify the indoor air, improve the indoor air quality, and thus improve the comfort of customers.

As shown in Fig. 6, the air outlet side of the air treatment duct is located above the centrifugal water-spinning member 35a and the air inlet side of the air treatment duct is located at the side or bottom of the water container 40, which can facilitate the purification of indoor air by the water treatment member 30. The rotation axis of the centrifugal water-spinning member 35a extends longitudinally, and the centrifugal water-spinning member 35a is configured to spray water around the rotation axis of the centrifugal water-spinning member 35a, so that the structure of the centrifugal water-spinning member 35a can be simpler and is conducive to the rapid formation of the water curtain 355.

As shown in Fig. 6, the centrifugal water-spinning member 35a includes a water-spinning wheel 351 and a rotating shaft 352. The water-spinning wheel 351 is configured to form a negative pressure zone extending from the water-spinning wheel 351 to the water container 40 when rotating to suck water in the water container 40 and form the sucked water into a water curtain 355, thereby purifying the indoor air. Specifically, when the centrifugal water-spinning member 35a is working, the water-spinning wheel 351 can rotate, a negative pressure is formed in the water container 40, the water-spinning wheel 351 sucks water in the water container 40 and sprays water around by rotating itself, and forms a water curtain 355 in the air treatment duct under the action of centrifugal force.

The water wheel 351 is located directly above the water container 40, and the water curtain 355 is sprayed toward the inner wall of the water container 40, so that the water curtain 355 can fully purify the indoor air, thereby improving the indoor air quality. For example, when the centrifugal water-spinning member 35a is working, the water in the water container 40 is sucked into the water wheel 351 from bottom to top, and the water wheel 351 rotates around its rotation axis. The water wheel 351 sprays water around during the rotation process, thereby forming a hemispherical water curtain 355 in the air treatment duct.

A water flow path extending along the axial direction is defined in the rotating shaft 352, one end of the water flow path extends to the water wheel 351, and the other end of the water flow path extends into the water container 40, so that the water in the water container 40 can be easily sucked into the water wheel 351, which is conducive to the formation of the water curtain 355.

The centrifugal water-spinning member 35a is provided with a centrifugal pump and a driving motor (not shown in the figure), and the water-spinning wheel 351 is provided as a hollow disc-shaped member, and a plurality of water outlet holes are provided on the bottom wall and the side wall of the water-spinning wheel 351. The centrifugal pump is provided in the water container 40, and the centrifugal pump can pump the water in the water container 40 into the hollow space of the water-spinning wheel 351 through the water flow path in the rotating shaft 352. The driving motor is connected to the rotating shaft 352, and the driving motor can rotate the rotating shaft 352, thereby driving the water-spinning wheel 351 to rotate. When the centrifugal water-spinning member 35a is working, the centrifugal pump pumps the water in the water container 40 into the water-spinning wheel 351 through the water flow path in the rotating shaft 352, and the driving motor drives the rotating shaft 352 to rotate. The water in the water flow path is sprayed from the water outlet holes on the bottom wall and the side wall of the water-spinning wheel 351 to the surroundings of the water-spinning wheel 351 during the rotation of the water-spinning wheel 351, thereby forming a water curtain 355 in the air treatment duct.

Thus, by providing a rotatable centrifugal water-spinning member 35a, the centrifugal water-spinning member 35a can form a water curtain 355 in the air treatment duct by using the centrifugal force through its own rotation. When the indoor air flows through the air treatment duct, it passes through the water curtain 355. The water molecules in the water curtain 355 can absorb dust and dust particles in the indoor air and melt them into the water, thereby purifying the indoor air and improving the indoor air quality.
