[0057]

[0058] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed embodiments

[0059] It should be noted that if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the technical features indicated. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution where A and B are satisfied simultaneously.

[0060] The present invention provides an air treatment device, which can be used alone or can be mounted on devices such as air conditioners, purifiers, and air machines. The air conditioner can be a split air conditioner, such as a floor-mounted air conditioner or a wall-mounted air conditioner, or an integrated air conditioner, such as a window air conditioner or a mobile air conditioner. The air treatment device can humidify, purify, sterilize, remove formaldehyde, add fragrance, etc. to the air. The specific structure of the air treatment device will be described in detail below.

[0061] In an embodiment of the present invention, as Figures 1 to 3 shown, the air treatment device 10 includes a housing 100, a first air treatment module 210, a second air treatment module 220, a first turbocharged fan 310, and a second turbocharged fan 320. A first air treatment air duct 111 and a second air treatment air duct 112 are provided in the housing 100. The first air treatment module 210 and the first turbocharged fan 310 are disposed in the first air treatment air duct 111, and the second air treatment module 220 and the second turbocharged fan 320 are disposed in the second air treatment air duct 112.

[0062] In this embodiment, the overall shape of the housing 100 can be cylindrical, cubic, cuboid, irregular, or other combined shapes, which can be selected and designed according to actual usage requirements and will not be specifically limited herein. The first air treatment module 210 and the second air treatment module 220 can specifically include one or more of a purification module, a fragrance module, a humidification module, and an electrolyzed water module, and generally the first air treatment module 210 is different from the second air treatment module 220. In this way, different air treatments are performed on the air flow in the first air treatment air duct 111 and the second air treatment air duct 112. It can be understood that the first air treatment air duct 111 and the second air treatment air duct 112 can be independently arranged or communicatively arranged. The first air treatment air duct 111 and the second air treatment air duct 112 can be arranged side by side or in a three-dimensional staggered manner, and their specific arrangement methods and positions can be selected and designed according to actual needs and will not be specifically limited herein.

[0063] It should be noted that a turbocharged fan refers to a fan that, through the rotation of the turbine 311, compresses the air in the volute, and then enables the air flow to flow out after being pressurized, so that the turbine 311 can compress more air into the fan. The air treatment device 10 adopts a turbocharged fan, which has a small air flow inlet area and a greater suction force, and can meet the characteristics of duct air outlet and small-area air inlet, thereby making the overall occupied space of the air treatment device 10 smaller. This turbocharged fan can be a turbocharged centrifugal fan, a turbocharged mixed-flow fan, and of course, it can also be other types of fans. The types of the first turbocharged fan 310 and the second turbocharged fan 320 can be the same or different. The first air treatment module 210 and the first turbocharged fan 310 are arranged in the first air treatment duct 111, and the first turbocharged fan 310 is used to drive the air flow into the first air treatment duct 111, and after being processed by the first air treatment module 210, it is blown out into the room. The second air treatment module 220 and the second turbocharged fan 320 are arranged in the second air treatment duct 112, and the second turbocharged fan 320 is used to drive the air flow into the second air treatment duct 112, and after being processed by the second air treatment duct 112, it is blown out into the room.

[0064] In the air treatment device 10 of the present invention, the first air treatment module 210 and the first turbocharged fan 310 are arranged in the first air treatment duct 111, and the second air treatment module 220 and the second turbocharged fan 320 are arranged in the second air treatment duct 112. Then, turbocharged fans are adopted in both the first air treatment duct 111 and the second air treatment duct 112 of the air treatment device 10. They have a small air flow inlet area and a greater suction force, and can meet the characteristics of duct air outlet and small-area air inlet. Thus, while the air treatment device 10 has multi-functional air treatment, it occupies less space, can meet the air inlet requirements of the duct layout in a narrow space, and is more conducive to the layout of other structural spaces in the housing 100.

[0065] Specifically, please refer to Figures 7 to 9 as well. The housing 100 is provided with a first air inlet 121, a first air outlet 131 communicating with the first air treatment duct 111, a second air inlet 122, and a second air outlet 132 communicating with the second air treatment duct 112. The first turbocharged fan 310 is used to drive the air flow to flow into the first air treatment duct 111 from the first air inlet 121, and after being processed by the first air treatment module 210, it is blown out from the first air outlet 131. The second turbocharged fan 320 is used to drive the air flow to flow into the second air treatment duct 112 from the second air inlet 122, and after being processed by the second air treatment module 220, it is blown out from the second air outlet 132.

[0066] In this embodiment, the first air inlet 121 and the second air inlet 122 may be opened on the same side of the housing 100, or may be opened on different sides of the housing 100. The first air outlet 131 and the second air outlet 132 may be opened on the same side of the housing 100, or may be opened on different sides of the housing 100. Air inlet grilles may be provided at the first air inlet 121 and the second air inlet 122 to prevent dust, debris, etc. from entering the first air treatment duct 111 and the second air treatment duct 112. Grille structures may be provided at both the first air outlet 131 and the second air outlet 132 to make the air flow blown out from the first air outlet 131 and the second air outlet 132 more uniform and softer. The shapes and sizes of the first air inlet 121, the first air outlet 131, the second air inlet 122, and the second air outlet 132 may be selected and designed according to actual usage requirements, and no specific limitations are made herein.

[0067] Specifically, the first air inlet 121, the first air outlet 131, the second air inlet 122, and the second air outlet 132 are all in communication with the interior of the room. In this way, the first turbocharged fan 310 is used to drive the air flow to flow into the first air treatment duct 111 from the first air inlet 121, and after being processed by the first air treatment module 210, it is blown out from the first air outlet 131, so that the indoor air flow is circulated and processed by the first air treatment module 210. The second turbocharged fan 320 is used to drive the air flow to flow into the second air treatment duct 112 from the second air inlet 122, and after being processed by the second air treatment module 220, it is blown out from the second air outlet 132. Then the indoor air flow is circulated and processed by the second air treatment module 220. Of course, in other embodiments, the first air inlet 121 and / or the second air inlet 122 may also be in communication with the outside. To perform relevant air treatment on the outside air flowing into the room. It can be understood that the first turbocharged fan 310 may be turned on simultaneously or selectively, so that the air treatment device 10 can perform the first air treatment and the second air treatment simultaneously, or the air treatment device 10 can only perform the first air treatment or the second air treatment.

[0068] In one embodiment, as Figures 7 to 18 shown, a communication duct 140 is further provided in the housing 100. The communication duct 140 has a first end 141 and a second end 142. The first end 141 is in communication with the first air treatment duct 111, and the second end 142 is in communication with the second air treatment duct 112. A movable first switch door 410 is provided in the communication duct 140, and the first switch door 410 is used to block and conduct the communication duct 140.

[0069] In this embodiment, the first switch door 410 can be rotatably installed in the communication air duct 140 or slidably installed in the communication air duct 140, as long as it can switch between blocking and conducting the communication air duct 140. Generally, the first switch door 410 is driven by a driving motor to rotate to block or conduct the communication air duct 140. By making the communication air duct 140 communicate with the first air treatment air duct 111 and the second air treatment air duct 112, it is equivalent to connecting the first turbocharged fan 310 and the second turbocharged fan 320 in series. In this way, the processing efficiency of the first air treatment module 210 can be enhanced by the second turbocharged fan 320, and the processing efficiency of the second air treatment module 220 can be enhanced by the first turbocharged fan 310. Moreover, when both the first air treatment module 210 and the second air treatment module 220 process air, the air processed by the first air treatment module 210 can be fully mixed with the air processed by the second air treatment module 220 and then blown out, thereby improving the air treatment effect of the entire air treatment device 10.

[0070] Further, please refer to Figure 7 , Figure 10 , Figure 13 and Figure 16 . In the air outlet direction of the first air treatment air duct 111, the first air treatment module 210 is located upstream of the first turbocharged fan 310. In the air outlet direction of the second air treatment air duct 112, the second air treatment module 220 is located upstream of the second turbocharged fan 320. The first end 141 is located between the first air treatment module 210 and the first turbocharged fan 310, and the second end 142 is located between the second air treatment module 220 and the second turbocharged fan 320.

[0071] In this embodiment, in the air outlet direction of the first air treatment air duct 111, the first air treatment module 210 is located upstream of the first turbocharged fan 310, that is, after the first turbocharged fan 310 drives the air flow to enter the first air treatment air duct 111 from the first air inlet 121, the air flow first passes through the first air treatment module 210 and then flows into the first turbocharged fan 310, and then is blown out from the first air outlet 131. In the air outlet direction of the second air treatment air duct 112, the second air treatment module 220 is located upstream of the second turbocharged fan 320, that is, after the second turbocharged fan 320 drives the air flow to enter the second air treatment air duct 112 from the second air inlet 122, the air flow first passes through the second air treatment module 220 and then flows into the second turbocharged fan 320, and then is blown out from the second air outlet 132.

[0072] By making the first end 141 of the communication duct 140 located between the first air handling module 210 and the first turbocharged fan 310, and the second end 142 located between the second air handling module 220 and the second turbocharged fan 320, when the first air inlet 121 is opened, the second air inlet 122 is closed, and the first switch door 410 is opened, the first turbocharged fan 310 drives the air flow to flow through the first air handling module 210 from the first air inlet 121. Part of the air flow is blown out from the first air outlet 131, and part of the air flow flows into the second air handling duct 112 under the drive of the second turbocharged fan 320 and is blown out from the second air outlet 132. In this way, it is equivalent to the first turbocharged fan 310 and the second turbocharged fan 320 simultaneously driving the air flow to flow into the first air handling duct 111 from the first air inlet 121 and being blown out from the first air outlet 131 and the second air outlet 132, so that the air volume in the first air handling mode can be increased, and the air handling efficiency and effect of the first air handling module 210 can be enhanced. When the second air inlet 122 is opened, the first air inlet 121 is closed, and the first switch door 410 is opened, the second turbocharged fan 320 drives the air flow to flow through the second air handling module 220 from the second air inlet 122. Part of the air flow is blown out from the second air outlet 132, and part of the air flow flows into the first air handling duct 111 under the drive of the first turbocharged fan 310 and is blown out from the first air outlet 131. In this way, it is equivalent to the first turbocharged fan 310 and the second turbocharged fan 320 simultaneously driving the air flow to flow into the second air handling duct 112 from the second air inlet 122 and being blown out from the first air outlet 131 and the second air outlet 132, so that the air volume in the second air handling mode can be increased, and the air handling efficiency and effect of the second air handling module 220 can be enhanced.

[0073] In one embodiment, as Figure 7 、 Figure 10 、 Figures 13 to 18 shown, a movable second switch door 420 is provided in the first air handling duct 111. The second switch door 420 is installed between the first air handling module 210 and the first end 141 for blocking and conducting the first end 141 and the first air inlet 121; and / or, a movable third switch door 430 is provided in the second air handling duct 112. The third switch door 430 is installed between the second air handling module 220 and the second end 142 for blocking and conducting the second end 142 and the second air inlet 122.

[0074] In this embodiment, the second switch door 420 can rotate or slide to switch between blocking and conducting the first end 141 and the first air inlet 121. The third switch door 430 can rotate or slide to switch between blocking and conducting the second end 142 and the second air inlet 122. Practically, the first switch door 410 can be driven by a driving motor to rotate to switch between blocking and conducting the first end 141 and the first air inlet 121, and the second switch door 420 can be driven by the driving motor to rotate to switch between blocking and conducting the second end 142 and the second air inlet 122. Specifically, the first air treatment module 210 can be a purification module, and the second air treatment module 220 can be a humidification module. Hereinafter, taking the first air treatment module 210 as a purification module and the second air treatment module 220 as a humidification module as an example, the working states and working principles of the air treatment device 10 in various modes will be described. In this way, the air treatment device 10 has a humidification + purification mode, a purification enhancement mode, and a humidification enhancement mode.

[0075] When the air treatment device 10 is in the humidification + purification mode, the first switch door 410 is closed, the second switch door 420 and the third switch door 430 are opened. The first turbocharged fan 310 drives the air flow to enter the first air treatment air duct 111 from the first air inlet 121, and after being purified by the purification module, it is blown out from the first air outlet 131. The second turbocharged fan 320 drives the air flow to enter the second air treatment air duct 112 from the second air inlet 122, and after being humidified by the humidification module, it is blown out from the second air outlet 132, so as to realize the humidification + purification mode of the air treatment device 10.

[0076] When the air treatment device 10 is in the purification enhancement mode, the first switch door 410 is opened, the second switch door 420 is opened, and the third switch door 430 is closed. The first turbocharged fan 310 drives the air flow to enter the first air treatment air duct 111 from the first air inlet 121. After being purified by the purification module, part of the air flow is blown out from the first air outlet 131, and part of the air flow is driven by the second turbocharged fan 320 and enters the second air treatment air duct 112 through the connecting air duct 140 without flowing through the humidification module and is directly blown out from the second air outlet 132. In this way, by driving the air flow through the purification module by the first turbocharged fan 310 and the second turbocharged fan 320 at the same time, the purification air volume, purification efficiency and purification effect of the air treatment device 10 can be effectively improved.

[0077] When the air treatment device 10 is in the enhanced humidification mode, the first switch door 410 is opened, the second switch door 420 is closed, and the third switch door 430 is opened. The second turbo blower 320 drives the air flow to enter the second air treatment air duct 112 from the second air inlet 122. After being humidified by the humidification module, part of the air flow is blown out from the second air outlet 132, and part of the air flow is driven by the first turbo blower 310, enters the first air treatment air duct 111 through the connecting air duct 140, does not flow through the purification module, and is directly blown out from the first air outlet 131. In this way, by simultaneously driving the air flow through the humidification module by the first turbo blower 310 and the second turbo blower 320, the humidification air volume, humidification efficiency and humidification effect of the air treatment device 10 can be effectively improved.

[0078] Of course, the air treatment module also has a single humidification mode and a single purification mode. In the single humidification mode and the single purification mode, the first switch door 410 is closed, and the second switch door 420 or the third switch door 430 is opened to implement the single humidification mode and the single purification mode. By setting the second switch door 420, the second switch door 420 is installed between the first air treatment module 210 and the first end 141 to block and conduct the first end 141 and the first air inlet 121; the third switch door 430 is installed between the second air treatment module 220 and the second end 142 to block and conduct the second end 142 and the second air inlet 122, so that the air treatment device 10 has a single humidification mode, a single purification mode, a humidification mode plus a purification mode, a purification enhancement mode, and a humidification enhancement mode. In this way, the modes of the air treatment device 10 are diversified, which can meet the different usage requirements of users and improve the user experience.

[0079] Furthermore, as Figure 2 、 Figure 3 、 Figure 17 and Figure 18 shown, the housing 100 is also provided with an air outlet 150 communicating with the connecting air duct 140, and an air supply switch door 440 is provided at the air outlet 150 to open and close the air outlet 150.

[0080] In this embodiment, specifically, the air supply opening 150 is located between the first end 141 and the second end 142 of the communication duct 140. The air supply switch door 440 is movably installed on the housing 100, so that the air supply opening 150 can be rotated to open or closed, or can be slid to open or closed. By additionally providing the air supply opening 150 and the air supply switch door 440 communicating with the communication duct 140, the air treatment device 10 also has an air supply mode. When the air treatment device 10 is in the air supply mode, the air supply switch door 440 and the first switch door 410 are opened, and the second switch door 420 and the third switch door 430 are closed. In this way, the first turbocharged fan 310 drives the air flow to enter the communication duct 140 from the air supply opening 150, flows into the first air treatment duct 111, does not flow through the purification module, and then is blown out from the first air outlet 131. The second turbocharged fan 320 drives the air flow to enter the communication duct 140 from the air supply opening 150, flows into the second air treatment duct 112, does not flow through the humidification module, and then is blown out from the second air outlet 132. In this way, the air treatment device 10 has a separate air supply mode without purification and humidification treatment, so that the air treatment device 10 can also be used as a fan, which can improve the service life of the humidification module and the purification module and meet different user needs.

[0081] In one embodiment, please refer to Figure 3 and Figure 7 , the first air treatment module 210 and the first turbocharged fan 310 are located at the lower part of the housing 100, and the second air treatment module 220 and the second turbocharged fan 320 are located at the upper part of the housing 100.

[0082] In this embodiment, by arranging the first air treatment module 210 and the first turbocharged fan 310 at the lower part of the housing 100, and the second air treatment module 220 and the second turbocharged fan 320 at the upper part of the housing 100, the main components of the first air treatment duct 111 and the main components of the second air treatment duct 112 are arranged vertically, making full use of the space in the vertical direction inside the housing 100, reducing the horizontal layout space, so that the structure of the entire air treatment device 10 is more compact, and further reducing the volume and occupied space of the air treatment device 10, making the air treatment device 10 more miniaturized while having multiple functions.

[0083] Furthermore, as Figures 3 to 5 , Figure 7 shown, the air treatment device 10 further includes a left bracket 510 and a right bracket 520 arranged in the housing 100 and extending in the up and down direction. The first air treatment module 210 and the second turbocharged fan 320 are installed on the left bracket 510, and the second air treatment module 220 and the first turbocharged fan 310 are installed on the right bracket 520.

[0084] In this embodiment, the left bracket 510 and the right bracket 520 can be attached to each other or arranged at intervals. Of course, the left bracket 510 and the right bracket 520 can also be integrally formed. The left bracket 510 and the right bracket 520 are arranged side by side in the horizontal direction. If the first air treatment module 210 and the second turbocharged fan 320 are installed on the left bracket 510, and considering that the first air treatment module 210 is located at the lower part of the housing 100 and the second turbocharged fan 320 is located at the lower part of the housing 100 as described above, then the first air treatment module 210 is installed at the lower part of the left bracket 510 and the second turbocharged fan 320 is installed at the upper part of the left bracket 510. If the second air treatment module 220 and the first turbocharged fan 310 are installed on the right bracket 520, and considering that the second air treatment module 220 is located at the upper part of the housing 100 and the first turbocharged fan 310 is located at the lower part of the housing 100 as described above, then the second air treatment is located at the upper part of the right bracket 520 and the first turbocharged fan 310 is located at the lower part of the housing 100.

[0085] By installing the first air treatment module 210 and the second turbocharged fan 320 on the left bracket 510, and the second air treatment module 220 and the first turbocharged fan 310 on the right bracket 520, the overall structure is made more compact, and the installation of each structure is made more convenient and stable. Also, the first turbocharged fan 310 and the second turbocharged fan 320 are staggered in the up-down and left-right directions, and the first air treatment module 210 and the second air treatment module 220 are staggered in the up-down and left-right directions, avoiding the center of gravity shift of the entire air treatment device 10, effectively preventing the deformation of the installation structure or the housing 100, and making the first air treatment module 210 close to the first turbocharged fan 310 and the second air treatment module 220 close to the second turbocharged fan 320. While making the overall structure of the machine more compact, it can further ensure the air treatment effect of the first air treatment module 210 and the second air treatment module 220.

[0086] In one embodiment, please refer to Figures 1 to 3 、 Figure 7 The first air inlet 121 is opened on the peripheral side wall of the housing 100 and is arranged corresponding to the first air treatment module 210. The second air inlet 122 is opened on the peripheral side wall of the housing 100 and is arranged corresponding to the second air treatment module 220. The first air outlet 131 and the second air outlet 132 are opened on the top wall of the housing 100.

[0087] In this embodiment, the combined first air treatment module 210 and the second turbocharged fan 320 are installed on the left bracket 510, and the second air treatment module 220 and the first turbocharged fan 310 are installed on the right bracket 520. Then, the first air inlet 121 and the second air inlet 122 are respectively arranged on two opposite side walls of the housing 100. The first air inlet 121 is arranged at the lower part of the housing 100, and the second air inlet 122 is arranged at the upper part of the housing 100. In this way, the air flow entering from the first air inlet 121 is directly treated by the first air treatment module 210, and the air flow entering from the second air inlet 122 is directly treated by the second air treatment module 220. This improves the treatment efficiency of the first air treatment module 210 and the second air treatment module 220, and enables the air flow entering the first air treatment air duct 111 to be treated by the first air treatment module 210, and the air flow entering the second air treatment air duct 112 to be treated by the second air treatment module 220, thus improving the treatment effect of the entire air treatment device 10. By arranging the first air outlet 131 and the second air outlet 132 on the top wall of the housing 100, the first air treatment air duct 111 extends from bottom to top, making the flow path of the first air treatment air duct 111 longer, and thus effectively improving the treatment effect of the first air treatment module 210 in the first air treatment air duct 111.

[0088] In one embodiment, as Figure 3 shown, an aroma adding channel 160 is further provided in the housing 100, and the aroma adding channel 160 is communicated with the first air treatment air duct 111 and / or the second air treatment air duct 112.

[0089] In this embodiment, the aroma adding channel 160 can be arranged in the first air treatment air duct 111 and the second air treatment air duct 112, or can be arranged independently of the first air treatment air duct 111 and the second air treatment air duct 112. Aroma modules can be arranged in the aroma adding channel 160, such as adding substances that can emit fragrances, such as flower petals and essential oils. By making the aroma adding channel 160 communicate with the first air treatment air duct 111 and / or the second air treatment air duct 112, the first turbocharged fan 310 and the second turbocharged fan 320 can be effectively utilized to drive the air flow in the first air treatment air duct 111 and / or the second air treatment air duct 112 to flow into the aroma adding channel 160, accelerating the fragrance emission of the aroma modules in the aroma adding channel 160, thereby realizing the function of adding aroma.

[0090] Furthermore, please refer to Figures 1 to 3 , the air treatment device 10 further includes an aromatherapy grille 600. The aromatherapy grille 600 and the top wall of the housing 100 enclose to form the aroma adding channel 160. The aromatherapy grille 600 is rotatably installed on the top wall of the housing 100 to block and conduct the first air treatment air duct 111 and / or the second air treatment air duct 112 and the aroma adding channel 160.

[0091] In this embodiment, the aromatherapy grille 600 is rotatably installed on the top wall of the housing 100 to block and conduct the first air treatment air duct 111 and / or the second air treatment air duct 112 and the flavoring channel 160. Then, the aromatherapy grille 600 is equivalent to a switching valve. When the aromatherapy grille 600 is opened, the air flow in the first air treatment air duct 111 and / or the second air treatment air duct 112 can enter the flavoring channel 160, thereby being able to increase the volatilization rate of the flavor module in the flavoring channel 160 and realizing the aromatherapy opening function. When the aromatherapy module is closed, the flavoring channel 160 is isolated from the first air treatment air duct 111 and the second air treatment air duct 112, so that the flavor module in the flavoring channel 160 volatilizes naturally, thus realizing the aromatherapy closing function. By arranging the aromatherapy grille 600 and the top wall of the housing 100 to enclose the flavoring channel 160, the flavor air flow can be emitted from the aromatherapy grille 600 into the room, and the opening and closing of the aromatherapy function can be switched by rotating the aromatherapy grille 600, which can meet more usage requirements of users.

[0092] In one embodiment, as Figure 3 shown, the housing 100 includes a main body 170, an air outlet grille, and an air outlet frame 180 installed on the top of the main body 170. The top of the air outlet frame 180 is provided with an open mouth. The air outlet grille is installed at the open mouth of the air outlet frame 180. The inner cavity of the air outlet frame 180 is communicated with the first air treatment air duct 111 and / or the second air treatment air duct 112. An air outlet ring 181 protrudes towards the air outlet grille in the middle of the air outlet frame 180. The aromatherapy grille 600 is arranged to cover the air outlet ring 181 and encloses the flavoring channel 160 with the air outlet ring 181. A plurality of first air outlet holes 182 are provided on the peripheral wall of the air outlet ring 181 at intervals along its circumferential direction. Second air outlet holes 610 corresponding to the first air outlet holes 182 are provided on the peripheral wall of the aromatherapy grille 600. The aromatherapy grille 600 is rotatably installed on the air outlet frame 180 around the circumferential direction of the air outlet ring 181 to conduct and block the first air outlet holes 182 and the second air outlet holes 610.

[0093] In this embodiment, the top of the main body 170 is open, and the air outlet frame 180 is installed at the open part of the main body 170. The first air treatment duct 111 and the second air treatment duct 112 are formed in the main body 170, and the first air outlet 131 and the second air outlet 132 are formed on the top of the main body 170. A connecting hole can be provided on the air outlet frame 180 to connect the inner cavity of the air outlet frame 180 with the first air treatment duct 111 and / or the second air treatment duct 112, and an air inlet gap can also be formed between the air outlet grille and the air outlet frame 180 so that the first air treatment duct 111 and / or the second air treatment duct 112 enter the inner cavity of the air outlet frame 180 through the air outlet gap. The aroma grille 600 is adapted to the air outlet ring 181, and the aroma grille 600 can rotate relative to the air outlet ring 181. The aroma grille 600 can be set on the outer side of the air outlet ring 181, or it can be set on the inner side of the air outlet ring 181. The shape of the first air outlet 182 and the second air outlet 610 can be circular, rectangular, long strip, etc., which can be selected and designed according to actual needs. Optionally, the first air outlet 182 is adapted to the second air outlet 610. When the aroma grille 600 rotates to the point where the first air outlet 182 corresponds to the second air outlet 610, part of the airflow in the first air handling duct 111 and / or the second air handling duct 112 flowing into the inner cavity of the air outlet frame 180 can flow through the first air outlet 182 and the second air outlet 610 in sequence, and enter the air outlet circle 181 and the aroma channel 160 in the aroma grille 600, which can accelerate the volatilization of the fragrance module in the aroma channel 160, and realize the opening of the aroma function of the air treatment device 10. When the aroma grille 600 rotates to the point where the first air outlet 182 and the second air outlet 610 are staggered, the airflow in the inner cavity of the air outlet frame 180 cannot flow into the aroma channel 160, and is directly blown out of the air outlet grille, thereby realizing the closing of the aroma function of the air treatment device 10.

[0094] The user can manually rotate the aroma grille 600, or drive the aroma grille 600 to rotate automatically by a driving motor. In this way, the aroma function can be turned on or off independently, and the aroma function can be turned on in combination with the air supply mode, the purification mode, and the humidification mode. The air treatment device 10 has an aroma function, and the various modes of the air treatment device 10 can be combined in different ways to meet more user needs.

[0095] In one embodiment, please refer to Figure 3 , Figures 7 to 18, the first air treatment module 210 includes a purification module, and the second air treatment module 220 includes a humidification module. The purification module may specifically include one or more of a plasma net, a formaldehyde removal net, a HEPA net, an activated carbon net, a water washing purification module, an allergen removal module, a negative ion module, and an electrostatic dust removal module. Specifically, the purification module includes a HEPA net, a formaldehyde removal net, and a plasma net, and the plasma module, the formaldehyde net, and the HEPA net are sequentially arranged in the air inlet direction of the first air inlet 121. The humidification module may specifically include a wet film 222 assembly or an atomization assembly. The humidification module further has a water tank. The atomization assembly is placed in the water tank, and water is supplied to the water tank through the water tank 221 to achieve humidification of the indoor air. The atomization assembly may be an ultrasonic atomization part. The wet film 222 may also be placed in the water tank, and water passes through the lower end of the wet film 222, and the wet film 222 is integrally wetted through the water absorption effect of the wet film 222 itself. Or water is guided to the upper side of the wet film 222 through a water pump to directly wet the wet film 222 to achieve humidification of the indoor air. By making the first air treatment module 210 include a purification module and the second air treatment module 220 include a humidification module, the air treatment device 10 can have a purification function and a humidification function. Of course, in other embodiments, a dehumidification module, a heating module, an electrolyzed water module, an oxygen generation module, etc. may also be provided in the air treatment device 10. The air treatment device 10 can specifically select different functions according to usage requirements and add different components, and the combination forms are not listed one by one here.

[0096] Further, as Figure 3 shown, the humidification module includes a water tank 221 and a wet film 222. The water tank 221 is used to supply water to the wet film 222, and a water filling port communicating with the water tank 221 is provided on the housing 100. Specifically, the wet film 222 can be set as a semi-circular wet film 222, which can increase the humidification area and improve the humidification effect. The humidification module further has a water tank. The wet film 222 is placed in the water tank, and water is supplied to the water tank through the water tank 221. Water passes through the lower end of the wet film 222, and the wet film 222 is integrally wetted through the water absorption effect of the wet film 222 itself. Or water is guided to the upper side of the wet film 222 through a water pump to directly wet the wet film 222 to achieve humidification of the indoor air. By providing a water filling port on the housing 100, the user can directly add water to the water tank 221 from the outside without having to take out the water tank 221 separately for water addition, making the water addition operation of the water tank 221 simpler and faster. Specifically, a water filling cover is provided at the water filling port, and the water filling cover covers the water filling port. Then the user can add water to the water tank 221 through the water filling port by opening the water filling cover. The provision of the water filling cover can prevent dust, debris, etc. from entering the water tank 221. Optionally, the water filling port is provided on the top wall of the housing 100, which further facilitates the user to perform the water addition operation.

[0097] Specifically, please refer to Figure 3 and Figure 6, the first turbocharged fan 310 is a turbocharged centrifugal fan, and the second turbocharged fan 320 is a turbocharged centrifugal fan. This makes both the first turbocharged fan 310 and the second turbocharged fan 320 be turbocharged centrifugal fans, which have low noise, stable operation, and can make the air inlet smaller compared to other fans under the same air output. This can meet the air inlet requirements of the narrow duct layout in a narrow space, is more conducive to the layout of other structural spaces inside the housing 100, and thus is conducive to reducing the volume of the entire air treatment device 10.

[0098] Furthermore, as Figure 6 shown, the turbocharged centrifugal fan includes a turbine 311 and a guide cover 312 covering the outer periphery of the turbine 311. One end of the guide cover 312 forms an air inlet end. The turbine 311 includes a hub 3111 and a plurality of blades 3112 provided on the outer periphery of the hub 3111. The plurality of blades 3112 are arranged at intervals along the circumferential direction of the hub 3111. The inner diameter of the hub 3111 is gradually increased from the side close to the air inlet end of the guide cover 312 to the side far from the air inlet end of the guide cover 312.

[0099] In this embodiment, the turbocharged centrifugal fan further includes a motor and a volute. The turbine 311 and the guide cover 312 are arranged inside the volute. The volute is provided with an air inlet and an air outlet. The motor is connected to the turbine 311 to drive the turbine 311 to rotate. The guide cover 312 covers the outer periphery of the turbine 311. When the turbine 311 rotates, the air flow of the vortex supercharged centrifugal fan is introduced into the guide cover 312 from one end of the guide cover 312, and the air flow is squeezed between the blades 3112 of the turbine 311 and between the turbine 311 and the guide cover 312. Then, the air flow flows out from the circumferential side of the guide cover 312 and finally flows out from the air outlet of the volute. Making the inner diameter of the hub 3111 gradually increase from the side close to the air inlet end of the guide cover 312 to the side far from the air inlet end of the guide cover 312 can achieve effective supercharging, and thus can increase the air intake of the first turbocharged fan 310 and the second turbocharged fan 320. Specifically, the plurality of blades 3112 are all three-dimensional twisted blades 3112. Compared with the centrifugal blades 3112 with equal cross-sections, the turbocharged fan has a larger air volume and lower noise.

[0100] In one embodiment, please refer to Figure 3 , Figure 6 and Figure 7, the outer peripheral wall of the fairing 312 is provided with a gas outlet 3121, and the gas outlet 3121 spirally extends around the axis of the fairing 312 from the air inlet end away from the fairing 312 towards the air inlet end close to the fairing 312. In this way, the air flow pressurized by the blades 3112 between the turbine 311 and the fairing 312, after flowing out from the gas outlet of the fairing 312, undergoes secondary spiral pressurization, thereby enhancing the pressurization effect, and effectively improving the air intake volume of the entire turbocharged fan. In other words, compared with other fans, the entire turbocharged fan can have a smaller air inlet area while achieving the same air output volume, and thus can reduce the occupied space of the entire air handling device 10.

[0101] The present invention also provides an air conditioner indoor unit, as Figure 19 shown. The air conditioner indoor unit includes an air handling device 10, and the specific structure of the air handling device 10 refers to the above embodiments. Since this air conditioner indoor unit adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. The air conditioner indoor unit can be a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, etc. Hereinafter, the floor-standing air conditioner indoor unit will be taken as an example for illustrative purposes.

[0102] In one embodiment, please refer to Figure 19 and Figure 20 , the air conditioner indoor unit further includes a main unit. The main unit 20 includes an indoor heat exchange module; the air handling device 10 is detachably connected to the main unit 20.

[0103] In this embodiment, the overall shapes of the main unit 20 and the air handling device 10 can be cylindrical, elliptical cylindrical, square cylindrical or other shapes. The shapes of the main unit 20 and the air handling device 10 can be the same or different. Specifically, it can be selected and designed according to actual usage requirements, and is not limited here. The main unit 20 extends in the up and down direction as a whole, and the main unit 20 and the air handling device 10 can be provided with equal cross-sections or variable cross-sections in the up and down direction. The indoor heat exchange module has a heat exchange air duct. The indoor heat exchange module is used for heat exchange of the air flow flowing through the heat exchange air duct to achieve refrigeration or heating. The indoor heat exchange module can only have a refrigeration function, or can have both refrigeration and heating functions at the same time. It can be understood that the main unit 20 further includes a heat exchange air inlet and a heat exchange air outlet communicated with the heat exchange air duct. A heat exchange component is provided in the heat exchange air duct. The heat exchange component includes a heat exchanger and a heat exchange fan. The heat exchange fan drives the air flow to enter the heat exchange air duct from the heat exchange air inlet, and after heat exchange through the heat exchanger, blows out from the heat exchange air outlet, thereby realizing indoor refrigeration or heating. Among them, the indoor heat exchange module further includes structures such as refrigerant pipes and compressors, and its specific structure can refer to the existing technologies of floor-standing air conditioner indoor units, which will not be elaborated here.

[0104] The air handling device 10 is detachably connected to the main unit 20. Then, the air handling device 10 can be connected inside the main unit 20. For example, a receiving cavity 21 is provided inside the main unit 20 so that the air handling device 10 is installed in the receiving cavity 21. At this time, the receiving cavity 21 can be located at the upper, middle or lower part of the main unit 20. The air handling device 10 can also be connected outside the main unit 20, such as being spliced at the bottom, top, peripheral side, etc. of the main unit 20. The connection between the air handling device 10 and the main unit 20 can be a structural connection. For example, it can be connected by means of snap connection, magnetic attraction connection, plug connection, etc. It can be understood that the air handling device 10 can be separated from the main unit 20 by manual disassembly by the user, or the air handling device 10 can be actively separated from the main unit 20 by the control device without manual operation by the user. When the air handling device 10 is detached from the main unit 20, it can move cyclically indoors independently to meet the needs of the entire indoor air treatment and make the air supply in the whole space uniform. It can also be manually moved by the user to move the air handling device 10 to the required position indoors or make the air handling device 10 move to a certain position independently, such as an area where many people gather, so as to be able to meet the fixed-point air supply in a certain area, realize long-distance, fixed-point and directional air supply, and improve the air treatment effect. Compared with moving the entire floor-standing air conditioner indoor unit, the movement of the air handling device 10 is more flexible and convenient, so as to be able to meet the different usage needs of users. Moreover, the air handling device 10 can perform relay air supply on the air flow blown out from the heat exchange air outlet of the main unit 20, so that the air supply distance is farther and the air supply range is wider.

[0105] In the air conditioner indoor unit of the present invention, the air handling device 10 is detachably connected to the main unit 20, and the air handling device 10 can be detached from the main unit 20 to work independently. While ensuring rapid heat exchange in the whole room, the air handling device 10 can be detached from the main unit 20 to realize whole-house mobile air supply, etc. Then, the air supply requirements of a certain area or the whole area in the room can be flexibly adjusted through the air handling device 10, so that the whole floor-standing air conditioner indoor unit has high flexibility and can meet the different air supply needs of users. Moreover, the air handling device 10 can perform relay air supply on the heat exchange air flow blown out by the main unit 20, so as to achieve long-distance and multi-directional air supply. At the same time, while enabling the floor-standing air conditioner indoor unit to supply air in multiple directions, over a long distance and throughout the house, the air handling device 10 is connected to the main unit 20, so as to realize the integration and storage of multiple machines, save room space and improve space utilization rate.

[0106] Further, a receiving cavity 21 is provided at the lower part of the main unit 20, and the air handling device 10 is detachably installed in the receiving cavity 21.

[0107] In this embodiment, the accommodation cavity 21 can be located at the upper, middle or lower part of the main body 20. The accommodation cavity 21 can be located below or above the heat exchange air duct. Of course, in a specific model, the accommodation cavity 21 and the heat exchange air duct can also be arranged side by side in the horizontal direction. Generally, the shape of the accommodation cavity 21 is adapted to the shape of the air handling device 10, that is, when in the non-working state, the air handling device 10 is fully accommodated in the accommodation cavity 21. Of course, part of the air handling device 10 can also be located inside the accommodation cavity 21 and part outside the accommodation cavity 21, that is, part is exposed outside the main body 20. The accommodation cavity 21 can be formed by partially hollowing out the main body 20. The accommodation cavity 21 can also be formed by enclosing with support arms on the main body 20. By arranging at least part of the air handling device 10 in the accommodation cavity 21 of the main body 20, compared with the overall splicing of the air handling device 10 and the main body 20, it is easier to maintain the overall consistency after the two are connected, thereby improving the user experience.

[0108] The air handling device 10 is detachably installed in the accommodation cavity 21. Then, the air handling device 10 can be directly placed in the accommodation cavity 21 and separated from the accommodation cavity 21 by means of rolling, sliding, etc. The air handling device 10 can also be installed in the accommodation cavity 21 by means of a limiting structure, such as being connected in the accommodation cavity 21 by means of snap connection, magnetic attraction connection, etc. There are many forms for the air handling device 10 to be installed in and separated from the accommodation cavity 21, which will not be listed one by one here. The air handling device 10 can be manually removed from the accommodation cavity 21 by the user, so that the air handling device 10 is separated from the main body 20. It can also be controlled to autonomously move out of the main body 20 by the air handling device 10. At this time, the accommodation cavity 21 needs to be arranged at the bottom of the main body 20 so that the air handling device 10 can autonomously move out of the accommodation cavity 21.

[0109] In one embodiment, as Figures 1 to 3 、 Figure 20 shown, the air handling device 10 further includes a control device and a moving device 700. The moving device 700 is installed at the bottom of the housing 100, and the control device is used to control the moving device 700 to drive the air handling device 10 to move.

[0110] In this embodiment, the mobile device 700 can be installed at the bottom of the housing 100, or the support arm can be connected to the side wall or the top of the housing 100.

Thus, the air handling device 10 is equivalent to an air-conditioning robot, and can adjust the movement direction according to the feedback of the indoor environment and autonomously plan the walking route, so as to ensure that the air handling device 10 can avoid obstacles and walk flexibly. Temperature, humidity or pollutant sensors 800, etc. can also be provided, so that the air handling device 10 can detect the environmental state of a certain area during the movement process, and thus can autonomously judge whether to leave or stay to continue blowing air. Of course, a vision sensor 800 can also be provided on the air handling device 10. The air handling device 10 moves to take panoramic images of the house interior and can upload them to the cloud system. Then, the user can observe the movement of the air handling device 10 at any time through intelligent devices such as mobile phones, tablets, and computers. Of course, the control device can also be used to control the air handling device 10 to disconnect from the host 20.

[0111] In one embodiment, the control device includes a controller and a sensor 800 for receiving a roadblock signal. The controller is used to plan a walking route according to the roadblock signal of the sensor 800 and control the mobile device 700 to drive the air handling device 10 to move.

In this way, the detection effect and accuracy of the entire air handling device 10 are better. After the air handling device 10 is detached from the accommodation cavity 21, the sensor 800 scans and detects the environment where the air handling device 10 is located, so as to be able to understand the local area of the entire room and autonomously plan the walking route. Moreover, during the movement of the air handling device 10, the sensor 800 also senses obstacles (such as furniture, steps, carpets, etc. that hinder the movement of the air handling device 10) at a certain distance. After sensing the obstacles, the air handling device 10 can perform operations such as backing and turning, enabling it to avoid obstacles autonomously, effectively avoiding collisions, and planning the walking route in real time according to the room situation. In this way, it is ensured that the air handling device 10 can autonomously plan the walking route according to the complex indoor environment and adjust the walking mode according to the feedback of the indoor environment, so as to realize the flexible walking of the air handling device 10 indoors.

[0113] Specifically, temperature, humidity, or pollutant sensors 800, etc. can also be arranged on the housing 100, so that during the movement of the air handling device 10, the environmental state of a certain area can be detected, and thus it can autonomously judge whether to leave or stay for continuous air supply. For example, when it is detected that the temperature is high in an area where many people are concentrated, there is a lot of dust, high or low humidity in a certain area, the air handling device 10 stays and conducts continuous air supply, and selects the processing function of the air handling module according to the feedback situation to realize corresponding air treatment. When it is detected that the air parameters meet the requirements, it can leave to another area. In this way, it can meet the fixed-point air supply in a certain area, realize long-distance, fixed-point, and directional air supply, and improve the air treatment effect. Of course, a vision sensor 800 can also be arranged on the air handling device 10. The air handling device 10 moves to take panoramic images of the house interior and can upload them to the cloud system, so that users can observe the movement of the air handling device 10 at any time through intelligent devices such as mobile phones, tablets, and computers. Compared with moving the entire floor-standing air conditioner indoor unit, the air handling device 10 can move autonomously and plan the walking route according to the environment, making the movement of the air handling device 10 more flexible and convenient, so as to meet the different usage needs of users, with high intelligence and simple operation.
