[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The air treatment device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] like Figure 1 and Figure 2 As shown, the air treatment device 100 according to the embodiment of the utility model includes a housing 1, a fan assembly 2, a water receiving tray 3, a rotor 4 and a driving assembly 5.

[0043] Specifically, Figure 1 and Figure 2As shown, the housing 1 has an air inlet 110 and an air outlet 120. The air enters the housing 1 from the air inlet 110, and after being processed by the air treatment device 100, leaves the air treatment device 100 from the air outlet 120. The air inlet 110 can be connected only to the indoor environment, or only to the outdoor environment, or selectively to the indoor environment and the outdoor environment. When the air inlet 110 is connected to the indoor environment, the gas entering the air inlet 110 is the indoor gas, which can realize the circulation of indoor wind. When the air inlet 110 is connected to the outdoor environment, the gas entering the air inlet 110 is the outdoor gas, which can realize the function of introducing fresh air into the room. Further, the fan assembly 2 is arranged in the housing 1, and is used to drive the air flow from the air inlet 110 to the air outlet 120, ensuring the flow direction of the gas while providing power for the gas flow, so that the gas enters the air inlet 110 and leaves the air treatment device 100 from the air outlet 120.

[0044] In addition, the water receiving tray 3 is arranged in the housing 1, and the water receiving tray 3 has a certain depth, so it has a certain water storage capacity. The runner 4 is rotatably arranged in the housing 1, and the rotation axis of the runner 4 can be parallel to the horizontal plane, which is convenient for the installation and effective operation of the runner 4 in the housing 1. The runner 4 is arranged above the water receiving tray 3 and partially located in the water receiving tray 3, and is used to lift the water in the water receiving tray 3 to humidify the gas, which can realize the function of humidifying the gas of the air treatment device 100. Specifically, under the drive of the fan assembly 2, the gas enters the housing 1 from the air inlet 110 and flows through the runner 4. Part of the runner 4 is located in the water receiving tray 3 and can lift the water in the water receiving tray 3 during the rotation process. The gas flowing through the runner 4 contacts the water lifted in the runner 4, so that part of the water vaporizes or evaporates, and the gas becomes moist, thereby achieving the purpose of humidifying the gas. After the gas flowing through the runner 4 is humidified, it leaves the air treatment device 100 from the air outlet 120 under the drive of the fan assembly 2.

[0045] In addition, if Figure 1 As shown, the driving assembly 5 is disposed in the housing 1 and connected to the rotating wheel 4, and is used to drive the rotating wheel 4 to rotate. Figure 3 As shown, the rotating wheel 4 includes a plurality of rotating disks 41, a first end plate 42 and a second end plate 43. The plurality of rotating disks 41 are arranged at intervals in the thickness direction of the rotating disks 41 and are connected to each other. The first end plate 42 and the second end plate 43 are respectively arranged on both sides of the plurality of rotating disks 41 in the thickness direction of the rotating disks 41. The first end plate 42, the second end plate 43 and the plurality of rotating disks 41 are connected to each other and rotate synchronously, which can ensure the effective operation of the rotating wheel 4, has a simple and reasonable structure and low operating cost. Figure 5 and Figure 6In the example shown, a rotating shaft 421 is provided on the surface of the first end plate 42 on the side away from the rotating disk 41, and a motor shaft 431 is provided on the surface of the second end plate 43 on the side away from the rotating disk 41. The motor shaft 431 and the axis of the rotating shaft 421 are coaxially arranged and the motor shaft 431 is connected to the driving assembly 5. The driving assembly 5 can provide power for the rotation of the motor shaft 431. A special-shaped hole is provided on the end surface of the motor shaft 431 on the side away from the second end plate 43, such as Figure 5 In the example shown, a hole with a semicircular cross-section is provided in the motor shaft 431, and a driving shaft corresponding to the special-shaped hole on the motor shaft 431 is provided on the driving component 5. The driving shaft on the driving component 5 can be inserted into the special-shaped hole in the motor shaft 431 and transmit power to rotate the motor shaft 431. With the mutual cooperation of the coaxially arranged motor shaft 431 and the rotating shaft 421, the rotating wheel 4 can be rotated. The structure is simple and easy to assemble, and the operating cost is low.

[0046] Furthermore, if Figure 2 and Figure 4 As shown, at least one surface of the turntable 41 in the thickness direction has a water-lifting structure 411. During the rotation of the runner 4, the lower part of the runner 4 is immersed in the water stored in the water receiving tray 3. When the parts of the multiple turntables 41 immersed in the water leave the water surface, the water can be lifted up by the water-lifting structure 411. The lifted water will form a water film on the surface of the turntable 41 under the action of gravity. When the dry gas flows through the surface of the turntable 41, a part of the water vaporizes or evaporates after contacting with the gas, making the gas moist and increasing the humidity of the gas, thereby achieving the purpose of humidifying the gas. On the other hand, the multiple turntables 41, the first end plate 42 and the second end plate 43 can be made of stainless steel or aluminum alloy, which is easy to process, has high structural strength, is corrosion-resistant and has a long service life. In addition, only water is consumed during the humidification process. The runner 4 can be recycled and reused, can be cleaned and reused, does not need to be replaced regularly, and has low maintenance costs.

[0047] Furthermore, if Figure 2 and Figure 4 As shown, the water-lifting structure 411 is formed as a groove or a protrusion provided on the surface of the rotating disk 41, and has a simple structure and is easy to process. The rotation direction of the wheel 4 is the first direction. When the water-lifting structure 411 is a protrusion, the protrusion is a curved shape protruding away from the first direction, and the concave side of the protrusion can form a water storage area, so that the protrusion has a certain water storage capacity, thereby ensuring the water-lifting effect of the water-lifting structure 411 and the humidification effect of the gas. At the same time, the protruding direction of the protrusion located above the rotating disk 41 is opposite to the flow direction of the airflow, which can prevent the gas entering from the air inlet 110 from blowing directly toward the protruding direction of the protrusion, thereby avoiding the air blowing phenomenon of the air treatment device 100.

[0048] Preferably, the protrusion is arc-shaped, which has a simple shape and is easy to process, and is convenient to arrange on the turntable 41.

[0049] Furthermore, if Figure 2 and Figure 4 As shown, the protrusions are multiple and spaced apart, which can effectively increase the amount of water lifted during the rotation of the turntable 41. The multiple protrusions are multiple rows spaced apart along the radial direction of the turntable 41, and each row of protrusions includes multiple protrusions spaced apart along the circumferential direction of the turntable 41. The number of multiple rows of protrusions is equal, and the multiple protrusions in any two adjacent rows of protrusions are arranged one by one in the radial direction of the turntable 41, so that the arrangement of the multiple protrusions on the turntable 41 is more neat and orderly, and the space on the surface of the turntable 41 can be effectively utilized to a greater extent, and it is also convenient for the two protrusions arranged oppositely in the two adjacent rows of protrusions to cooperate with each other. Among them, the multiple protrusions in each row are arranged at intervals along the circumferential direction of the turntable 41, which is conducive to the multiple protrusions cooperating with the turntable 41 to realize the water lifting function when the turntable 41 rotates along the first direction, so as to ensure a certain amount of water lifting, thereby ensuring the humidification effect.

[0050] Furthermore, if Figure 2 and Figure 4 As shown, of any two protrusions arranged opposite and adjacent to each other in the radial direction, the protrusion located on the radial outer side is the first protrusion, and the protrusion located on the radial inner side is the second protrusion. In the first direction, the radial inner end of the first protrusion exceeds the radial outer end of the second protrusion. When the runner 4 rotates in the first direction, the water raised by the first protrusion will flow out from the radial inner end of the first protrusion under the action of gravity and flow into the second protrusion, so that the water on the surface of the turntable 41 forms multiple groups of micro-cascade-like water flows, and then forms a water film, which increases the contact area between water and air. The micro-cascade-like water flow can also accelerate the vaporization and evaporation rate of water, thereby enhancing the humidification effect of the runner 4 on the air.

[0051] Furthermore, the area of ​​the figure formed by the contour line of the protrusion and the connecting line of the two ends of the protrusion is the water storage area, and the water storage area of ​​the protrusion located on the radial outer side in any two adjacent rows of protrusions is larger than the water storage area of ​​the protrusion located on the radial inner side. It is more conducive to the water stored in the protrusion located on the radial outer side to continuously flow to the protrusion located on the radial inner side to form a micro-waterfall-like water flow, better ensure the quality of the water film formed on the surface of the rotating disk 41, and further enhance the humidification effect of the wheel 4 on the air.

[0052] Furthermore, if Figure 2 and Figure 4As shown, the center of the turntable 41 has an opening 412 that penetrates the turntable 41 in the thickness direction of the turntable 41, and the openings 412 of the multiple turntables 41 are arranged relatively. The wheel 4 also includes a water absorbent 44, which is cylindrical and is sleeved in the multiple openings 412. The water absorbent 44 has high water absorption and high air permeability. The water raised on the turntable 41 will eventually flow to the water absorbent 44 and be absorbed by the water absorbent 44. The air can flow through and pass through the water absorbent 44, while taking away the moisture in the water absorbent 44, forming a second level of humidification, making the effect of humidifying the air more significant. Among them, the water absorbent 44 is a non-woven spunlace fabric, a PP piece or a 3D mesh fabric, which has the advantages of high water absorption, quick wetting, high air permeability, washability, not easy to breed bacteria or mildew, environmental protection and hygiene, etc.

[0053] According to the air treatment device 100 of the embodiment of the utility model, the water receiving tray 3 and the rotating wheel 4 are arranged in the housing 1, and the rotating wheel 4 is rotatably arranged above the water receiving tray 3 and partially located in the water receiving tray 3, so that the water in the water receiving tray 3 can be lifted to humidify the gas entering from the air inlet 110, thereby realizing the function of humidifying the gas of the air treatment device 100. In addition, the rotating wheel 4 and other components can be recycled, can be cleaned and reused, and do not need to be replaced regularly, which is convenient for later maintenance and has low maintenance costs.

[0054] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air treatment device 100 also includes an electric heating device 6, which is arranged in the housing 1 and is used to heat the gas, so as to realize the gas heating function of the air treatment device 100 and the indoor heating function. At the same time, the air inlet 110 is connected to the outdoor environment, and when fresh air is introduced outdoors, the temperature of the fresh air introduced outdoors can be heated to avoid the direct introduction of outdoor cold air into the room, thereby ensuring the comfort of the user. On the other hand, the temperature of the gas will increase after passing through the electric heating device, and water will be more easily vaporized or evaporated when it contacts the gas with increased temperature, so that the gas becomes moist, which is conducive to enhancing the humidification effect of the gas.

[0055] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, along the air flow direction, the electric heating device 6 is located upstream of the rotor 4. The electric heating device 6 is arranged at the air inlet 110. When the gas enters the housing 1 from the air inlet 110, it will first pass through the electric heating device 6 and then flow through the rotor 4. The gas is first heated by the electric heating device 6, so that the dry gas with increased temperature is convenient for heat exchange with water when flowing through the rotor 4. The water is more easily evaporated into steam by heat, and the gas will therefore become high-humidity gas at room temperature and blown out from the air outlet 120, thereby ensuring the humidification effect of the air treatment device 100 on the gas.

[0056] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air treatment device 100 further includes a first temperature and humidity sensor 7 and a second temperature and humidity sensor 8, which are both arranged in the housing 1 and are respectively located at the air inlet 110 and the air outlet 120. The first temperature and humidity sensor 7 can detect the temperature and humidity content of the gas flowing through the air inlet 110, and the second temperature and humidity sensor 8 can detect the temperature and humidity content of the gas flowing through the air outlet 120. After the first temperature and humidity sensor 7 and the second temperature and humidity sensor 8 detect the temperature and humidity, they can respectively transmit signals to the electronic control component 9 connected to the communication therewith, and then calculate and analyze through the enthalpy difference method, and then control and adjust the parameters such as the air intake volume of the air treatment device 100, and then control the temperature and humidity in the room by controlling, for example, the rotation speed of the fan assembly 2 and the rotation speed of the wheel 4.

[0057] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air treatment device 100 also includes an electric control component 9, which is arranged in the housing 1. The electric control component 9 and the fan assembly 2 are arranged in a horizontal direction perpendicular to the flow of the airflow, so that the layout of the air treatment device 100 is more reasonable and the structure is more compact. The electric control component 9 is respectively connected to the fan assembly 2, the drive assembly 5 that drives the rotating wheel 4 to rotate, the electric heating device 6, the first temperature and humidity sensor 7 and the second temperature and humidity sensor 8. For example, the first temperature and humidity sensor 7 and the second temperature and humidity sensor 8 transmit the temperature and humidity signals at the air inlet 110 and the air outlet 120 to the electric control component 9 connected thereto for communication. After calculation and analysis by the enthalpy difference method, when the air treatment device 100 needs to humidify the gas, the electric control component 9 will transmit the signal to the drive assembly 5 and the electric heating device 6. After receiving the signal, the drive assembly 5 starts to operate to drive the rotating wheel 4 to rotate, so that the gas can be heated when flowing through the electric heating device 6, and then heat exchange with water when flowing through the rotating rotating wheel 4, thereby realizing the function of humidifying the gas of the air treatment device 100.

[0058] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air treatment device 100 also includes a water level switch 10, which is arranged in the water receiving tray 3 and is used to monitor and control the water level in the water receiving tray 3. The water level switch 10 is communicated with the electronic control component 9 and can transmit the monitored water level signal in the water receiving tray 3 to the electronic control component 9, thereby ensuring the control of the water amount in the water receiving tray 3.

[0059] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the water level switch 10 includes a first water level switch 101 and a second water level switch 102. The working water level of the first water level switch 101 is lower than the working water level of the second water level switch 102. The first water level switch 101 and the second water level switch 102 cooperate with each other to limit and control the water level of the water in the water receiving tray 3. The first water level switch 101 is located at the lowest water level in the water receiving tray 3 that can ensure that the rotor 4 can play a humidification role. When the first water level switch 101 detects that the water in the water receiving tray 3 is at the lowest water level that can ensure that the rotor 4 can play a humidification role, it will transmit a signal that water needs to be replenished in the water receiving tray 3 to the electronic control component 9 connected thereto in communication, so as to ensure the gas humidification function of the air treatment device 100. The second water level switch 102 is at the highest water level that the water in the water receiving tray 3 can reach. The highest water level can ensure the humidification effect of the impeller 4 while ensuring that the water in the water receiving tray 3 will not overflow. When the second water level switch 102 detects that the water in the water receiving tray 3 is at the highest water level, it will transmit a signal that no water replenishment is needed in the water receiving tray 3 to the electronic control component 9 connected to it for communication, so as to ensure that the water in the water receiving tray 3 is at a safe water level and avoid water overflowing from the water receiving tray 3.

[0060] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air treatment device 100 also includes a water supply pipe and a control valve 11. The water supply pipe is arranged on the housing 1. One end of the water supply pipe located outside the housing 1 is connected to a water source, and water for humidification can be provided to the air treatment device 100. The control valve 11 is arranged in the housing 1 and connected to one end of the water supply pipe located in the housing 1. The control valve 11 is connected to the electronic control component 9 for communication. The control valve 11 is configured to be closed when the second water level switch 102 is working and open when the first water level switch 101 is working. When the first water level switch 101 is working, it is detected that the water in the water receiving tray 3 is at the lowest water level. After the first water level switch 101 transmits a signal to the electronic control component 9, the electronic control component 9 transmits a signal to open the control valve 11 to the control valve 11. When the control valve 11 is opened, water can enter the water receiving tray 3 through the water supply pipe to achieve the purpose of replenishing the water in the water receiving tray 3. When the second water level switch 102 is working, it is detected that the water in the water receiving tray 3 is at the highest water level. After the second water level switch 102 transmits a signal to the electric control component 9, the electric control component 9 transmits a signal to close the control valve 11 to the control valve 11, and the control valve 11 is closed, thereby stopping the water replenishment of the water receiving tray 3. By providing the water supply pipe and the control valve 11, the water inflow of the water receiving tray 3 can be effectively controlled, ensuring the humidification function of the air treatment device 100 while ensuring that the water in the water receiving tray 3 is at a safe water level.

[0061] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the water level switch 10 is located on the leeward side of the impeller 4 to prevent the gas entering from the air inlet 110 from directly blowing on the water level switch 10, thereby avoiding affecting the monitoring effect of the water level switch 10 on the water level in the water tray 3 and ensuring the working performance and service life of the water level switch 10.

[0062] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, along the airflow direction, the fan assembly 2 is located downstream of the impeller 4. When the gas enters the housing 1 from the air inlet 110 driven by the fan assembly 2, it will first flow through the impeller 4 for humidification, and then flow out from the air outlet 120 driven by the fan assembly 2. The fan assembly 2 being located downstream makes it easier for the fan assembly 2 and the air outlet 120 to cooperate and connect with each other, which is beneficial for the fan assembly 2 to provide driving force for the gas flow, and also makes the component layout of the air treatment device 100 more reasonable.

[0063] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air handling device 100 further includes a water pump 12 and an active drain pipe 13. The water pump 12 is arranged in the water receiving tray 3. The water inlet of the water pump 12 is communicated with the space in the water receiving tray 3. The active drain pipe 13 is penetrated on the housing 1 and one end is communicated with the water outlet of the water pump 12, so that the water pump 12 can extract the water in the water receiving tray 3 and discharge it outside the housing 1 through the active drain pipe 13. The water pump 12 is connected to the electronic control component 9 in communication. When the water in the water receiving tray 3 is higher than the highest safe water level or the water in the water receiving tray 3 needs to be drained during maintenance, the electronic control component 9 will transmit a signal to the water pump 12, so that the water pump 12 operates to extract the water in the water receiving tray 3 and discharge it through the active drain pipe 13. By providing the water pump 12 and the active drain pipe 13, water can be discharged during maintenance, which is convenient for maintenance operations. At the same time, it can prevent the water in the water receiving tray 3 from overflowing too high, and prevent the air handling device 100 from leaking.

[0064] In some embodiments of the present invention, Figure 1 As shown, the electronic control component 9, the drive assembly 5, the control valve 11 and the water pump 12 are all located on the same side of the width direction of the shell 1, and the electronic control component 9, the drive assembly 5, the control valve 11 and the water pump 12 are arranged in a horizontal direction parallel to the air flow, which is convenient for connecting the drive assembly 5, the control valve 11, the water pump 12 and the fan assembly 2 with the electronic control component 9, so that the layout of the air treatment device 100 is more reasonable and the structure is more compact.

[0065] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the exit position of the active drainage pipe 13 on the shell 1 is located on the same side of the shell 1 as the air inlet 110, which can effectively utilize the space around the air inlet 110, reduce the size and length of the air treatment device 100, and make the structure more compact and the layout more reasonable.

[0066] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, an overflow port is also provided on the side wall of the water receiving pan 3, and an overflow pipe is connected to the overflow port, and the overflow pipe is passed through the housing 1. The overflow port of the side wall is arranged at one end of the water receiving pan 3 close to the runner 4. When the water in the water receiving pan 3 is higher than the highest safe water level and reaches the height of the overflow port, the water will naturally flow out of the water receiving pan 3 from the overflow port and flow out of the housing 1 through the overflow pipe. Therefore, when the water level in the water receiving pan 3 rises uncontrollably due to damage to the water control valve, the water pump 12 or the electronic control component 9, the water in the water receiving pan 3 can be naturally discharged through the overflow port, which plays a certain preventive and protective role.

[0067] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the outlet position of the overflow pipe on the shell 1 is located on the same side of the shell 1 as the air inlet 110, which can effectively utilize the space around the air inlet 110, reduce the size and length of the air treatment device 100, and make the structure more compact and the layout more reasonable.

[0068] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air inlet 110 and the air outlet 120 are arranged on opposite sides of the housing 1, and the gas enters from one side of the housing 1 and flows out from the other side of the housing 1 after humidification, so that the air inlet and air outlet of the air treatment device 100 will not interfere with each other, the structural arrangement is more reasonable, and the effect of the air treatment device 100 on gas treatment can be guaranteed. Figure 1 As shown, two lifting ears are respectively provided on the opposite sides of the shell 1 having an air inlet 110 and an air outlet 120. The two lifting ears on each side are located at both ends of the shell 1 in the width direction and are arranged opposite to each other. The lifting ears are set at the upper end of the shell 1 to facilitate the installation of the air treatment device 100.
