[0037] Reference below Figure 1-Figure 7 An air treatment device 200 according to an embodiment of the present invention is described.

[0038] like Figure 1-Figure 7 As shown, the air treatment device 200 according to an embodiment of the present invention includes: a shell 10, a heating element 22 and a baffle assembly 20, the shell 10 is formed with a first air duct 11 and a second air duct 12, the first air duct 11 is used for supplying air, and the second air duct 12 is used for exhausting air, thereby realizing air circulation.

[0039] The heating element 22 is arranged in the first air duct 11; the baffle assembly 20 is arranged in the first air duct 11, and the baffle assembly 20 includes a baffle 21 and a valve plate 23. The baffle 21 is limited to an air outlet 213. The valve plate 23 is movably arranged on the baffle 21, and the valve plate 23 can block a part of the air outlet 213, thereby forming multiple flow paths in the first air duct 11, and the heating element 22 is located on a flow path. The heating element can heat the air on the flow path, and through the movement of the valve plate 23, the blocked part of the air outlet 213 can be changed, and then the circulation condition of the airflow in the first air duct 11 can be changed.

[0040] According to the air treatment device 200 of the embodiment of the present invention, the first air duct 11 is divided into multiple flow paths, which can expand the air supply working mode of the air treatment device 200; and the heating element 22 is located on one flow path, which can realize the function of introducing hot air, and the other flow path can realize the function of ventilation beside the heating element 22, thereby increasing the air supply volume of the first air duct 11, and reducing energy waste compared to the air inlet in which the heating element 22 covers the entire air duct; at the same time, there is no need to set multiple air outlets on the baffle 21, which is convenient for processing and manufacturing.

[0041] like Figure 1 As shown, in some examples, a partition baffle 13 is provided inside the shell 10, which can divide the space inside the shell 10 into a first air duct 11 and a second air duct 12, and the first air duct 11 and the second air duct 12 do not interfere with each other, so that the air intake function and the exhaust function of the air treatment equipment 200 do not interfere with each other, which can improve the air exchange efficiency of the air treatment equipment 200.

[0042] like Figure 2-Figure 7 As shown, according to some embodiments of the present invention, the first air duct 11 has a first flow path 111 and a second flow path 112, and the air outlet 213 includes a first area 211 and a second area 212. The position of the first area 211 corresponds to the position of the heating element 22 and is located on the first flow path 111. Air heated by the heating element 22 can flow in the first flow path 111.

[0043] When the valve plate 23 moves to a position, the valve plate 23 can block a part of the second area 212, so that another part of the second area 212 can be connected to the outside world. The other part of the second area 212 is located in the second flow path 112, and the second flow path 112 can supplement the air volume of the first flow path 111.

[0044] In some examples, the first air duct 11 also has a third flow path 113. When the valve plate 23 moves in the opposite direction, it can block another part of the second area 212, so that a part of the second area 212 can be connected to the outside world. A part of the second area 212 is located on the third flow path 113, and the third flow path 113 can supplement the air volume of the first flow path 111.

[0045] It can be understood that the second flow path 112 and the third flow path 113 have little wind resistance because there is no obstruction from the heating element, and both can compensate for the ventilation volume of the first flow path 111, thereby increasing the ventilation volume of the first air duct 11, thereby improving the air circulation efficiency of the air treatment equipment 200.

[0046] like Figure 5 and Figure 7 As shown, in some examples, the second flow path 112 can be located above the first flow path 111, and the third flow path 113 can be located between the first flow path 111 and the second flow path 112. It should be noted that the sum of the air outlet 213 portion corresponding to the second flow path 112 and the air outlet 213 portion corresponding to the third flow path 113 is smaller than the second area 212, that is, when the valve plate 23 moves, a portion of the second area 212 is always blocked. Of course, the partial size of the air outlet 213 corresponding to the second flow path 112 is as large as possible, and the partial size of the air outlet 213 corresponding to the third flow path 113 is also as large as possible. While ensuring the performance of the air treatment equipment 200, the speed of the fan in the air duct can be reduced, energy consumption can be saved, and the overall noise can be reduced, thereby improving the user experience.

[0047] like Figure 2 As shown, according to some embodiments of the present invention, the air treatment device 200 further includes: a drive component 24, the drive component 24 is arranged in the shell 10, and the drive component 24 cooperates with the valve plate 23, and the drive component 24 can be moved by driving the valve plate 23 to block a part of the air outlet 213. By moving the valve plate 23, the position of the blocked part of the air outlet 213 can be changed, and then the working mode of the air treatment device 200 can be changed, so that the air treatment device 200 has multiple working modes.

[0048] In some examples, the drive assembly 24 includes two, and the two drive assemblies 24 are arranged at intervals to facilitate the movement of the valve plate 23, so that the valve plate 23 is evenly stressed and moves smoothly. The two drive assemblies 24 can be arranged on both sides of the baffle 21 (such as Figure 1 The left and right sides shown in FIG), and the two drive components 24 are in the vertical direction (as Figure 1Of course, the two drive assemblies 24 can also have different heights to facilitate adjustment and good stability.

[0049] In some examples, the drive assembly 24 includes a drive motor 241, a gear 242 and a rack 243. The drive motor 241 is arranged in the first air duct 11, and the drive motor 241 is connected to the gear 242. The drive motor 241 can drive the gear 242 to rotate. The rack 243 is arranged on the valve plate 23, and the rack 243 can engage with the gear 242. The gear 242 drives the rack 243 to move by rotating, so that the rack 243 drives the valve plate 23 to move. Through the mutual cooperation between the gear 242 and the rack 243, not only the smoothness of the movement process of the valve plate 23 is improved, but also the accuracy of the moving position of the valve plate 23 is improved.

[0050] Of course, the driving component 24 can also be a motor, which directly drives the valve plate 23 to rotate. The driving component 24 can also include components for transmitting power such as rollers and belts. Among them, the driving motor 241 can drive the belt to move, thereby driving the roller to rotate, and then moving the valve plate 23, which can facilitate the control of the speed of movement of the valve plate 23. At the same time, the belt has low cost and is easy to maintain.

[0051] In some examples, in a direction perpendicular to the movement of the valve plate 23, both ends of the valve plate 23 extend to the outside of the baffle 21, thereby facilitating the connection between the valve plate 23 and the drive assembly 24. Specifically, both ends of the valve plate 23 (such as Figure 2 A rack 243 is provided at each of the left and right ends (as shown in the figure). The two racks 243 cooperate with each other to make the movement of the valve plate 23 highly synchronized, so that the valve plate 23 runs smoothly and the reliability of the air treatment equipment 200 is improved.

[0052] like Figure 1 As shown, according to some embodiments of the present invention, the air treatment device 200 also includes: a wheel assembly 100, the wheel assembly 100 is rotatably disposed in the shell 10, and the wheel assembly 100 is distributed in two air ducts, a part of the wheel assembly 100 is located in the first air duct 11, and the other part of the wheel assembly 100 is located in the second air duct 12, the wheel assembly 100 has an adsorbent that can adsorb and release moisture. For example, the material of the adsorbent can be silica gel, molecular sieve, etc. At this time, the adsorbent can adsorb moisture in the air at low temperature and dry the air, and the adsorbent can release moisture at high temperature and humidify the air, so there is no need to set up an additional water tank humidification or a built-in compressor, etc., thereby saving production costs.

[0053] Among them, the baffle assembly 20 is arranged between the heating element 22 and the wheel assembly 100. The air heated by the heating element 22 passes through the first flow path 111 to the wheel assembly 100, which can release the moisture adsorbed by the adsorption element, and then send the high-humidity air into the room through the first air duct 11, thereby improving the indoor comfort.

[0054] like Figure 3 As shown, in some examples, the wheel assembly 100 extends obliquely, the portion of the wheel assembly 100 close to the baffle 21 is adjacent to the top of the housing 10, and the portion of the wheel assembly 100 away from the baffle 21 is adjacent to the bottom of the housing 10, as shown in FIG. Figure 3 As shown, the wheel assembly 100 is tilted downward from front to back. By tilting the wheel assembly 100, the occupied thickness space can be reduced, that is, the size of the entire machine in the up and down directions can be reduced, the appearance is improved, and at the same time, it is convenient for the installation and use of the air treatment equipment 200 in different occasions.

[0055] It can be understood that by tilting the wheel assembly 100 so that the first flow path 111 and the third flow path 113 are both located below the entire wheel assembly 100, the air heated by the heating element 22 can fully contact the adsorption element, thereby improving the humidification effect of the wheel assembly 100 on the external air.

[0056] like Figure 3 、 Figure 5 and Figure 7 As shown, according to some embodiments of the present invention, the air treatment device 200 further includes a wheel partition 80, which is arranged at the rear side of the baffle 21 and moves away from the baffle 21 (eg, Figure 3 Since the wheel assembly 100 is tilted downward away from the baffle 21, the wind in the second flow path 112 is separated by the wheel partition 80 and does not need to pass through the wheel assembly 100, thereby reducing wind resistance, increasing air supply volume, and improving user experience.

[0057] like Figure 4 and Figure 5 As shown, in some examples, the valve plate 23 can move between a first position and a second position. In the first position, the valve plate 23 blocks the middle part of the air outlet 213, and the upper edge of the valve plate 23 is higher than the wheel partition 80. At this time, the lower part of the air outlet 213 can be connected to the outside world, and the upper part of the air outlet 213 can be connected to the outside world. The upper part of the air outlet 213 can supplement the ventilation volume in a working mode of the air treatment equipment 200. By setting the upper edge of the valve plate 23 higher than the wheel partition 80, the air in the upper part of the air outlet 213 can be prevented from flowing to other parts, thereby preventing air leakage.

[0058] like Figure 6 and Figure 7 As shown, when the valve plate 23 moves to the second position, the valve plate 23 blocks the upper part of the air outlet 213, and the lower edge of the valve plate 23 is lower than the wheel partition 80. At this time, the lower part of the air outlet 213 can be connected to the outside world, and the middle part of the air outlet 213 can be connected to the outside world. The middle part of the air outlet 213 can supplement the ventilation volume in another working mode of the air treatment equipment 200. By setting the lower edge of the valve plate 23 lower than the wheel partition 80, the air in the middle part of the air outlet 213 can be prevented from flowing to other parts, thereby achieving the effect of air leakage.

[0059] like Figure 1 As shown, according to some embodiments of the present invention, the housing 10 has a first air inlet 51, a first air outlet 52, a second air inlet 53 and a second air outlet 54, a first air duct 11 is formed between the first air inlet 51 and the first air outlet 52, and a second air duct 12 is formed between the second air inlet 53 and the second air outlet 54, wherein the first air inlet 51 and the second air outlet 54 are both located at one end of the air treatment device 200 (such as Figure 1 The first air outlet 52 and the second air inlet 53 are both located at the other end of the air treatment device 200 (as shown in FIG. Figure 1 As shown in the rear end, the first air inlet 51 can pass outdoor air into the first air duct 11, the first air outlet 52 can pass the air of the first air duct 11 into the room, the second air inlet 53 can pass the indoor air into the second air duct 12, and the second air outlet 54 can pass the air of the second air duct 12 into the outside, thereby realizing the ventilation function of the air treatment equipment 200.

[0060] like Figure 1 As shown, according to some embodiments of the present invention, the air treatment device 200 further includes: a first filter element 31 and a second filter element 32, the first filter element 31 and the second filter element 32 are arranged in the first air duct 11, and the two filter elements are located upstream of the heating element 22 (such as Figure 1 The filter element can purify the outside air and pass the purified outside air into the room.

[0061] Among them, the first filter element 31 is arranged in front of the second filter element 32. The second filter element 32 and the first filter element 31 can filter different impurities respectively. The second filter element 32 and the first filter element 31 cooperate with each other to improve the purification effect of the purification component.

[0062] Of course, the air treatment device 200 further includes: a third filter element 33, which can be disposed in the second air duct 12 and located upstream of the second air duct 12 (e.g., Figure 1As shown in the rear), by providing a third filter element 33, the indoor exhaust air can be filtered and cleaned to prevent dust and the like from entering the second air duct 12, thereby maintaining the cleanliness of the second air duct 12, facilitating maintenance, and reducing maintenance costs.

[0063] like Figure 1 As shown, in some examples, the air treatment device 200 also includes: a first fan 70 and a second fan 71, the first fan 70 is arranged at the rear end of the first air duct 11, the first fan 70 is arranged opposite to the first filter element 31, the second fan 71 is arranged at the front end of the second air duct 12, and the second fan 71 is arranged opposite to the third filter element 33, to ensure that the air enters the shell 10 after the filter element is cleaned, thereby improving the service life of the air treatment device 200.

[0064] like Figure 1 As shown, in some examples, the air treatment device 200 also includes: a controller 60, which can be arranged outside the shell 10, and the controller 60 can control the operating state of the air treatment device 200 according to user needs; the controller 60 can control the operation of the drive component 24 and the wheel drive 40, and by controlling the operation of the drive component 24, the drive component 24 can drive the valve plate 23 to flip, open and close the second air outlet and the third air outlet, and by controlling the wheel drive 40, the wheel drive 40 can drive the wheel assembly 100 to rotate, so that the part of the adsorption element located in the first air duct 11 releases moisture and can be rotated to the second air duct 12 to absorb moisture in the second air duct 12, thereby realizing the reuse of the wheel assembly 100, while ensuring the humidification performance of the air treatment equipment 200 on the air, saving production costs.

[0065] like Figure 4-Figure 7 As shown, in some examples, the air treatment device 200 includes a first working mode and a second working mode. In the first working mode, the heating element 22 works, and the valve plate 23 moves to block the middle part of the air outlet 213. At this time, the heated air can be introduced into the room through the first flow path 111. The heated air can cause the adsorbent to release moisture, thereby allowing the humidified air to be introduced into the room, and the second flow path 112 can supplement the filtered air to improve the fresh air supply effect.

[0066] In the second working mode, the valve plate 23 moves to block the upper part of the air outlet 213. At this time, the outside air can enter the room through the first flow path 111, and the third flow path 113 can supply filtered air. The air in the two flow paths can use the heat on the wheel assembly 100 to heat the outside air and then pass it into the room, thereby increasing the air supply temperature without the need for the heating element 22 to work, which can save energy, reduce usage costs, and improve user experience.

[0067] like Figure 1-Figure 7 As shown, according to some specific embodiments of the present invention, the air treatment equipment 200 includes: a shell 10, a partition baffle 13 and a wheel assembly 100, a controller 60 is arranged on the outside of the shell 10, and the partition baffle 13 divides the internal space of the shell 10 into a first air duct 11 and a second air duct 12, a heating element 22, a first filter element 31, a second filter element 32, a baffle assembly 20 and a first fan 70 are arranged in the first air duct 11, and a third filter element 33 and a second fan 71 are arranged in the second air duct 12, the first filter element 31, the second filter element 32 and the heating element 22 are arranged at the front end of the first air duct 11, the heating element 22 is located behind the two filter elements, the first fan 70 is located at the rear end of the first air duct 11, the second fan 71 is located at the front end of the second air duct 12, and the third filter element 33 is located at the rear end of the second air duct 12.

[0068] The wheel assembly 100 is arranged between the first air duct 11 and the second air duct 12, and is located in the middle of the air treatment equipment 200. The baffle assembly 20 is arranged between the heating element 22 and the wheel assembly 100. The baffle assembly 20 includes a baffle 21, a valve plate 23 and a drive assembly 24. The baffle 21 is defined with an air outlet 213, and the air outlet 213 includes a first area 211 and a second area 212. The second area 212 is located above the first area 211; the valve plate 23 is movably arranged on the baffle 21, and the valve plate 23 can cover a part of the second area 212. The drive assembly 24 includes: a drive motor 241, a gear 242 and a rack 243. The rack 243 is fixed on both sides of the valve plate 23. The drive motor 241 and the gear 242 are fixed inside the shell. The drive motor 241 can drive the gear 242 to rotate. The rack 243 is engaged with the gear 242, so that the rotation of the gear 242 drives the rack 243 to move.

[0069] like Figure 4 and Figure 5As shown, the first working mode is the humidification mode. In the first working mode, the controller 60 controls the driving assembly 24 and the rotary drive member 40, the driving motor 241 drives the gear 242 to rotate, the rack 243 engages with the gear 242, and then drives the valve plate 23 to move downward to cover the lower part of the second area 212, and the rotary drive member 40 controls the rotary assembly 100 to rotate the rotary assembly 100; the first fan 70 works, and the outdoor air first enters the first air duct 11 through the first air inlet 51, and then passes through the first filter element 31 and the second filter element 32. Part 32, the purified air is divided into two air flows at the front end of the heating part 22. One part of the air is heated by the heating part 22 and passes through the first flow path 111. The heated air absorbs the moisture in the adsorption part when passing through the rotor assembly 100, and carries the moisture to the rear of the first air duct 11. The other part of the air directly passes through the second flow path 112 and flows from the top of the rotor assembly 100 to the rear of the first air duct 11. The two parts of air flow to the rear of the first air duct 11, pass through the first fan 70, and enter the room from the first air outlet 52.

[0070] At the same time, the indoor air first enters the second air duct 12 through the second air inlet 53, and then passes through the third filter element 33 to reach the wheel assembly 100. At this time, the adsorption element that releases moisture in the first air duct 11 rotates into the second air duct 12 under the action of the wheel driving element 40. When the air in the second air duct 12 passes through the adsorption element, the moisture is absorbed by the adsorption element, and then passed into the outdoors from the second air outlet 54 through the second fan 71. The air forms a cycle in the circulation direction in the air treatment equipment 200, thereby realizing the fresh air exchange function of the air treatment equipment 200 and continuously humidifying the indoor air.

[0071] like Figure 6 and Figure 7 As shown, the second working mode is the heat recovery mode. In the second working mode, the heating element 22 stops working, the controller 60 controls the driving assembly 24 and the rotary drive member 40 to work, the driving motor 241 drives the gear 242 to rotate, the rack 243 engages with the gear 242, and then drives the valve plate 23 to move upward to cover the upper part of the second area 212, and the rotary drive member 40 controls the rotary assembly 100 to rotate the rotary assembly 100; the first fan 70 works, and the outdoor air first enters the first air duct 11 through the first air inlet 51, and then passes through the first filter element 31 and the second filter element 32 to reach the front end of the baffle assembly 20 and the heating element 22 (as shown in FIG. Figure 1 As shown in the front end of the figure, the purified air is divided into two air flows at the front end of the heating element 22. One part of the air passes through the first flow path 111, and the other part of the air passes through the third flow path 113. The two parts of air merge together and pass through the rotor assembly 100. At this time, the heat on the rotor assembly 100 can be taken away, so that the air enters the room from the first air outlet 52 after being heated.

[0072] At the same time, the indoor air first enters the second air duct 12 through the second air inlet 53, and then passes through the third filter element 33 to reach the rotor assembly 100. At this time, the heat in the second air duct 12 is adsorbed by the rotor assembly 100, and the air passes through the rotor assembly 100 and is discharged through the second fan 71. Among them, as the rotor assembly 100 rotates, when the part that absorbs heat rotates into the first air duct 11, it is taken away by the low-temperature air in the first air duct 11. This part of the rotor assembly 100 changes from a high-temperature rotor to a low-temperature rotor, and then enters the second air duct 12 to adsorb heat, and circulates in sequence; in the second working mode, the heating element 22 does not need to work, and the overall energy saving is more.
