[0079] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0080] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0081] The air treatment device provided in this embodiment is used to adjust the temperature, humidity, cleanliness, etc. of the indoor environment, improve the indoor air quality, and meet people's comfort requirements.

[0082] For example, the air handling device of this embodiment can be installed in a wall separating indoor and outdoor spaces, in a window pane, or on the side of a window. The air handling device can not only regulate the indoor environmental quality by itself, but also regulate the indoor environmental quality by obtaining outdoor air.

[0083] Combine Figures 1 to 24As shown, an embodiment of the present disclosure provides an air treatment device, comprising: a housing 10, a first ventilation module 20, and a second ventilation module 40. The first ventilation module 20 and the second ventilation module 40 are both disposed within the housing 10. The first ventilation module 20 and the second ventilation module 40 enable the air treatment device to have at least two ventilation modes, thereby improving the user experience.

[0084] The housing 10 includes an indoor panel 101 and an outdoor panel 102 that are arranged opposite to each other; the indoor panel 101 is the side facing indoors, and the outdoor panel 102 is the side facing outdoors.

[0085] The first ventilation module 20, installed in the housing 10, includes a first air outlet 201 and a first air return outlet 202 constructed on the indoor panel 101, as well as a second air return outlet 203 constructed on the outdoor panel 102. Air flowing out of the first air outlet 201 can flow in through the first air return outlet 202 and / or the second air return outlet 203. Air flowing into the first ventilation module 20 is blown out into the room through the first air outlet 201. The first ventilation module 20 provides two air intake pathways, via the first air return outlet 202 on the indoor panel 101 and the second air return outlet 203 on the outdoor panel 102. Specifically, the first air intake pathway of the first ventilation module 20 introduces outdoor air into the room through the second air return outlet 203. The second air intake pathway allows indoor air to flow into the first ventilation module 20 through the first air return outlet 202, where it is processed and then blown out into the room. Thus, the first ventilation module 20 enables the indoor processing device to not only regulate the temperature and humidity of the indoor air, but also provide fresh air.

[0086] The second ventilation module 40, located within the housing 10, includes a third return air vent 402 on the indoor panel 101 and a second air outlet 401 on the outdoor panel 102. The second ventilation module 40 is used to exhaust indoor air outdoors. This allows indoor air to be exhausted outdoors, refreshing the indoor air. In particular, if the concentration of harmful gases indoors is too high, these gases can be promptly expelled without opening windows.

[0087] The first ventilation module 20 and the second ventilation module 40 are independently arranged side by side. They do not interfere with each other and can be used independently or in combination. For example, when indoor air replacement is required, activating both the first ventilation module 20 and the second ventilation module 40 simultaneously not only achieves indoor air replacement but also maintains stable indoor air pressure, preventing disruption to users' daily lives.

[0088] The air treatment device provided by the embodiments of the present disclosure utilizes the first ventilation module 20 and the second ventilation module 40 to provide at least two ventilation modes. The first ventilation module 20 and the second ventilation module 40 can be used independently or in combination, thereby meeting various user needs and enhancing the user experience. Furthermore, the air treatment device can not only regulate the indoor environmental quality through the first ventilation module 20 itself, but can also regulate the indoor environmental quality by drawing in outdoor air through the second ventilation module 40.

[0089] Optionally, the first ventilation module 20 also includes a first fan 204, which is arranged in the casing 10 and corresponds to the first air outlet 201, and / or the second ventilation module 40 also includes a second fan 403, which is arranged in the casing 10 and corresponds to the second air outlet 401.

[0090] The first ventilation module 20 can promote air flow in the first ventilation module 20 through the first fan 204 to speed up the air handling device's adjustment of the indoor environment. The first fan 204 is arranged corresponding to the first air outlet 201 to help ensure the air volume of the first air outlet 201.

[0091] The second ventilation module 40 can promote air flow in the second ventilation module 40 through the second fan 403 to speed up the air handling device's adjustment of the indoor environment. The second fan 403 is arranged corresponding to the second air outlet 401 to help ensure the air volume of the second air outlet 401.

[0092] Optionally, the air treatment device also includes: a first air guide device 206, which is arranged at the first return air outlet 202, the second return air outlet 203 and / or the third return air outlet 402, for controlling the air flow interruption of the first return air outlet 202, the second return air outlet 203 and / or the third return air outlet 402.

[0093] When the first return air outlet 202, the second return air outlet 203 and / or the third return air outlet 402 are provided with the first air guide device 206, the corresponding return air outlet is opened or closed by the first air guide device 206, thereby controlling the air flow interruption of the corresponding return air outlet.

[0094] The first air return port 202 , the second air return port 203 and the third air return port 402 can be selectively installed with the first air guide device 206 according to actual conditions.

[0095] Optionally, the first air-guiding device 206 includes: a frame 2061, which is constructed with multiple ventilation parts 2062; a baffle 2071, which is slidably connected to the frame 2061 and is constructed with multiple hollow parts 2072 and shielding parts 2073 arranged at intervals; a first driving device, connected to the baffle 2071, for driving the baffle 2071 to slide to open or close the return air outlet; wherein, the return air outlet is opened when the hollow part 2072 corresponds to the ventilation part 2062, and the return air outlet is closed when the shielding part 2073 corresponds to the ventilation part 2062.

[0096] The frame 2061 of the first air guide device 206 is adapted to the size of the return air vent at the corresponding installation location. The first driving device drives the baffle 2071 to slide along the frame 2061. When the hollow portion 2072 of the baffle 2071 corresponds to the ventilation portion 2062 of the frame 2061, air can flow out of the return air vent through the hollow portion 2072 and the ventilation portion 2062. When the blocking portion 2073 corresponds to the ventilation portion 2062, the baffle 2071 completely blocks the ventilation portion 2062 of the frame 2061 through the blocking portion 2073, preventing air from flowing out of the return air vent through the ventilation portion 2062.

[0097] Optionally, the frame 2061 is detachably connected to the air return port of the housing 10. In this way, it is not only convenient to replace the first air guide device 206, but also possible to choose whether to install the first air guide device 206 according to actual conditions.

[0098] Figures 14 to 19 Schematic diagram of the structure of the air guide device for the return air outlet provided by the embodiment of the present disclosure. Figures 14 to 19 As shown, the air guide device for the return air outlet provided by the embodiment of the present disclosure includes a frame 2061, which is arranged at the return air outlet and is constructed with multiple ventilation parts 2062; a baffle 2071, which is slidably connected to the frame 2061 and is constructed with multiple hollow parts 2072 and shielding parts 2073 arranged at intervals; wherein, the return air outlet is opened when the hollow part 2072 corresponds to the ventilation part 2062, and is closed when the shielding part 2073 corresponds to the ventilation part 2062.

[0099] By using the wind guide device for the return air outlet provided by the embodiment of the present disclosure, the baffle 2071 slides back and forth along the frame 2061 so that the hollow portion 2072 and the shielding portion 2073 are respectively arranged to correspond to the ventilation portion 2062. When the ventilation portion 2062 corresponds to the hollow portion 2072, the air flow is allowed to flow, and when the ventilation portion 2062 corresponds to the shielding portion 2073, the air flow is blocked. In this way, the air flow at the return air outlet is controlled by the wind guide device, which not only has a simple structure and is easy to operate, but also the overall structure occupies a small space.

[0100] Optionally, the air guide device for the return air outlet further includes: a first driving device, connected to the baffle 2071, for driving the baffle 2071 to slide to open or close the return air outlet.

[0101] The first drive device is located on one side of the baffle 2071 and is connected to the baffle 2071 to drive the baffle 2071 to move back and forth along the frame 2061, thereby opening or closing the return air vent. In addition, by driving the baffle 2071 to move by the first drive device, the air guide device can also be operated automatically.

[0102] Optionally, the baffle 2071 includes: a rack portion 2074, which is provided on one side of the baffle 2071, and its length direction is consistent with the sliding direction of the baffle 2071; the first driving device includes: a gear portion 2082, which is meshed and connected to the rack portion 2074; a first motor 2081, which is transmission-connected to the gear portion 2082, and the first motor 2081 drives the gear portion 2082 to rotate, driving the rack portion 2074 to move, so as to drive the baffle 2071 to slide relative to the frame 2061.

[0103] The rack portion 2074 is located on the sliding direction side of the baffle 2071, and the length direction of the rack portion 2074 is consistent with the sliding direction of the baffle 2071. In this way, the first motor 2081 engages with the rack portion 2074 through the gear portion 2082, and the gear portion 2082 rotates, driving the rack portion 2074 to move, thereby driving the baffle 2071 to slide relative to the frame 2061.

[0104] Exemplarily, the first motor 2081 is driven to rotate forward and reverse to drive the baffle 2071 to move back and forth relative to the frame 2061, so that the hollow portion 2072 and the shielding portion 2073 are alternately arranged corresponding to the ventilation portion 2062, thereby realizing the opening and closing of the return air outlet.

[0105] Optionally, the baffle 2071 also includes: an extension portion 2075, which is extended from one side of the baffle 2071 along the length direction; wherein, the rack portion 2074 is arranged on one side of the extension portion 2075, and the top of the extension portion 2075 is higher than the top of the rack portion 2074, so that when the gear portion 2082 is engaged with the rack portion 2074, the extension portion 2075 limits the installation position of the gear portion 2082.

[0106] The extension portion 2075 can enhance the structural strength of the rack portion 2074 and support the rack portion 2074 and the gear when the gear and the rack portion 2074 are engaged.

[0107] By making the top of the extension portion 2075 higher than the top of the rack portion 2074, when the gear is meshed with the rack portion 2074, not only can the top edge of the extension portion 2075 limit the installation position of the gear and prevent the gear from protruding, thereby ensuring the contact area when the gear and the rack portion 2074 are meshed, but also during the reciprocating movement of the baffle 2071, the mutual cooperation between the gear and the extension portion 2075 can also play a certain guiding role on the baffle 2071.

[0108] Optionally, the plate surface of the extension portion 2075 is arranged perpendicular to the rack portion 2074 .

[0109] Optionally, the rack portion 2074 is located below the gear portion 2082 , and the end surface of the gear portion 2082 is in contact with or close to the plate surface of the extension portion 2075 .

[0110] The rack portion 2074 is located below the gear. When the gear and the rack portion 2074 are meshed and connected, the rack portion 2074 can provide a certain support to the gear, thereby ensuring the stability of the gear.

[0111] The end face of the gear is positioned in contact with or close to the surface of the extension 2075. This allows the extension 2075 to stop the gear, preventing it from protruding beyond the rack 2074 and affecting the contact area during meshing. Furthermore, during the reciprocating movement of the baffle 2071, the end face of the gear and the surface of the extension 2075 remain parallel and in contact, providing a guide for the movement of the baffle 2071.

[0112] Optionally, the air guide device for the return air outlet further includes: a mounting shell 2083 , which is recessed to form a mounting cavity 2084 for mounting the first motor 2081 .

[0113] The mounting shell 2083 is located inside the housing 10 of the air handling device and is detachably connected to the housing 10 .

[0114] The mounting shell 2083 is recessed to form a mounting cavity 2084, and the first motor 2081 of the first driving device is mounted and fixed in the mounting cavity 2084. Preferably, the size of the mounting cavity 2084 is adapted to the size of the first motor 2081.

[0115] For example, when the first motor 2081 is installed in the mounting cavity 2084, the first motor 2081 is detachably connected to the mounting cavity 2084 via fasteners. Furthermore, the first motor 2081 and the sidewall of the mounting cavity 2084 are in point contact as much as possible, or the contact area between the first motor 2081 and the sidewall of the mounting cavity 2084 is reduced, thereby helping to reduce vibration and noise transmitted to the mounting housing 2083 during operation of the first motor 2081.

[0116] Optionally, the edge of the frame 2061 is bent inward to form a groove 2063 , and the edge of the baffle 2071 is formed with a sliding portion 2076 , which is embedded in the groove 2063 to slide.

[0117] Through the structural design of the groove 2063 of the frame 2061 and the sliding part 2076 of the baffle 2071, the baffle 2071 is embedded in the groove 2063 of the frame 2061 through the sliding part 2076 and slides, which not only can achieve the purpose of relative fixation of the baffle 2071 and the frame 2061, but also can limit the position of the baffle 2071 and guide the sliding of the baffle 2071.

[0118] Optionally, the shape of the groove 2063 is adapted to the shape of the sliding portion 2076 .

[0119] Optionally, the inner side wall of the frame 2061 is constructed with a protruding protrusion 2064, and the top of the protrusion 2064 and the groove 2063 define an L-shaped structure; wherein the sliding portion 2076 of the baffle 2071 is bent to adapt to the L-shaped structure and overlaps the protrusion 2064.

[0120] In this way, an L-shaped structure is defined by the protrusion 2064 and the groove 2063. When the sliding part 2076 is embedded in the groove 2063, the protrusion 2064 supports the sliding part 2076, thereby preventing the sliding part 2076 from moving out of the groove 2063 perpendicular to the sliding direction.

[0121] The protrusion 2064 is arranged horizontally. The top of the sliding portion 2076 is bent and arranged perpendicularly to the baffle 2071, and overlaps the protrusion 2064. The protrusion 2064 stops the sliding portion 2076 from falling out of the groove 2063.

[0122] Optionally, the ventilation portion 2062 is in the shape of an elongated strip, and a plurality of ventilation portions 2062 are vertically arranged and evenly spaced.

[0123] The ventilation portion 2062 is in the shape of an elongated strip, and a plurality of ventilation portions 2062 are arranged vertically and evenly spaced, which helps to make the air flow out of the return air outlet uniform, and also helps to ensure the structural strength of the return air outlet.

[0124] Optionally, the air treatment device also includes: a third ventilation module 50, which is arranged in the casing 10, including a fourth return air outlet 501 constructed on the indoor panel 101 and a fifth return air outlet 502 constructed on the outdoor panel 102; wherein, a full heat exchange core 503 is provided in the third ventilation module 50, and can be selectively connected with the first ventilation module 20 and the second ventilation module 40, so that the air flow after heat exchange with the full heat exchange core 503 flows out from the first ventilation module 20 or from the second ventilation module 40.

[0125] The third ventilation module 50 draws in indoor air through the fourth return air port 501, heat-exchanges and conditions the air through the full heat exchange core 503, and then flows out through either the first ventilation module 20 or the second ventilation module 40, depending on the actual situation. This allows for temperature and humidity regulation of the indoor air. Furthermore, while the first ventilation module 20 or the second ventilation module 40 is functioning, the third ventilation module 50 can be used in conjunction with the first ventilation module 20 or the second ventilation module 40 to enhance air treatment efficiency and meet various user needs.

[0126] The third ventilation module 50 introduces outdoor air through the fifth return air port 502, and performs heat exchange regulation on the inhaled outdoor air through the full heat exchange core 503, and then blows it into the room through the first ventilation module 20 or the second ventilation module 40, so as to adjust the temperature and humidity of the indoor air with the help of the outdoor environment, improve the comfort of the indoor environment, and thus enhance the user experience.

[0127] The embodiment of the present disclosure also provides an air treatment device, including a casing 10, including an indoor panel 101 and an outdoor panel 102 arranged relatively to each other; a first ventilation module 20, arranged in the casing 10, including a first air outlet 201 and a first return air outlet 202 constructed on the indoor panel 101, and a second return air outlet 203 constructed on the outdoor panel 102; the air flow flowing out of the first air outlet 201 can flow into from the first return air outlet 202 and / or flow into from the second return air outlet 203; a third ventilation module 50, arranged in the casing 10, including a fourth return air outlet 501 constructed on the indoor panel 101 and a fifth return air outlet 502 constructed on the outdoor panel 102, and a full heat exchange core 503 is provided in the third ventilation module 50, and the full heat exchange core 503 is used to exchange heat with the air flow flowing in from the fourth return air outlet 501 and the fifth return air outlet 502; wherein the first ventilation module 20 and the third ventilation module 50 can be selectively connected.

[0128] The air treatment device provided by the embodiment of the present disclosure has at least two ventilation modules through the first ventilation module 20 and the third ventilation module 50, and indoor air or outdoor air is introduced through the third ventilation module 50. When used in conjunction with the first ventilation module 20, it can not only meet the user's various ventilation needs, but also improve the efficiency of regulating the indoor environment and enhance the user experience.

[0129] Optionally, the third ventilation module 50 includes: a third air duct 504 component, which is arranged in the casing 10 and encloses the third air duct 504 together with the casing 10; the full heat exchange core 503 is located in the third air duct 504 and is detachably connected to the third air duct 504 component; the third air duct 504 component is constructed with a ventilation port of the third air duct 504; a slide plate, which is slidably connected to the third air duct 504 component to open or close the air outlet of the third air duct 504; and a drive component, which is connected to the slide plate to drive the slide plate to slide along the third air duct 504 component.

[0130] The third ventilation module 50 opens or closes the vents of the third air duct 504 by sliding the slide plate, thereby achieving selective communication between the third ventilation module 50 and the first ventilation module 20. That is, when the drive assembly drives the slide plate to slide upward, the vents of the third air duct 504 are opened, thereby achieving communication between the third ventilation module 50 and the first ventilation module 20. The airflow in the third air duct 504 flows into the first ventilation module 20 and flows out through the first air outlet 201 of the first ventilation module 20.

[0131] In some embodiments, the third ventilation module 50 is selectively connected to the second ventilation module 40. That is, the slide slides to open the vent of the third air duct 504, thereby achieving communication between the third ventilation module 50 and the second ventilation module 40. The airflow in the third air duct 504 flows into the second ventilation module 40 and flows out through the second air outlet 401 of the second ventilation module 40.

[0132] Optionally, the third air duct 504 component also includes: a first partition 507, which is vertically arranged in the casing 10 and facing the first ventilation module 20; the first partition 507 is configured with a ventilation opening of the third air duct 504, and the edge of the first partition 507 is configured with a slide, which is used to be slidably connected to the first slide 509; the board surface of the first slide 509 is provided with a rack structure, and the first drive component 511 is arranged on the first partition 507, and the first drive component 511 is connected by a gear rack meshing connection to drive the first slide 509 to slide up and down in the slide to open or close the ventilation opening of the third air duct 504.

[0133] In this way, the first partition plate 507 can not only separate the first air duct 205 of the first ventilation module 20 and the third air duct 504 of the third ventilation module 50, but also can be used to install the first driving component 511 and the first slide 509, so that the first slide 509 can slide up and down in the slide along the first partition plate 507 under the drive of the first driving component 511, thereby opening or closing the ventilation port of the third air duct 504, and thus realizing selective connection between the first ventilation module 20 and the third ventilation module 50.

[0134] Optionally, the vent of the third air duct 504 is located on the lower side of the first partition plate 507, and the fourth return air vent 501 and the fifth return air vent 502 are both located above the vent of the third air duct 504. In this way, after the airflow enters the third air duct 504 from the fourth return air vent 501 or the fifth return air vent 502, it flows through the full heat exchange core 503 in the third air duct 504 and then flows out from the vent of the third air duct 504.

[0135] In addition, the ventilation port of the third air duct 504 is arranged on the lower side of the first partition 507. In this way, when the airflow in the third air duct 504 flows into the first ventilation module 20, it is mixed with the airflow flowing into the first ventilation module 20 and then blown out from the first air outlet 201 through the first fan 204; or, when the airflow in the third air duct 504 flows into the second ventilation module 40, it is mixed with the airflow flowing into the second ventilation module 40 and then blown out from the second air outlet 401 through the second fan 403.

[0136] Optionally, the first return air outlet 202 and the second return air outlet 203 are arranged correspondingly, and the first air outlet 201 is located above the first return air outlet 202; the first ventilation module 20 also includes: a first fan 204, which is arranged corresponding to the first return air outlet 202; wherein, the first return air outlet 202 and the second return air outlet 203 are both provided with a first air guide device 206, and the first air guide device 206 is used to open or close the return air outlet.

[0137] The first return air inlet 202 and the second return air inlet 203 are correspondingly arranged and located below the first air outlet 201. On the one hand, this helps to symmetrically arrange the structure of the air handling device and improve the stability of the overall structure. On the other hand, it facilitates the air to flow in from the low end and blow out from the high end, thereby enhancing the circulation of indoor air and improving the regulation effect on the indoor environment.

[0138] The first fan 204 is disposed corresponding to the first air return port 202 , which helps to increase the blowing distance of the airflow after being blown out from the first air return port 202 and expand the coverage of the airflow.

[0139] The first air guide device 206 is respectively provided through the first return air outlet 202 and the second return air outlet 203. In this way, the first return air outlet 202 and the second return air outlet 203 are controlled separately, and the corresponding return air outlet is opened or closed according to the actual situation, thereby realizing the control of multiple ventilation and air conditioning modes. For example, the air flow flowing into the first ventilation module 20 through the first return air outlet 202 comes from indoors, that is, the first ventilation module 20 regulates the indoor air itself. For example, the air flow flowing into the first ventilation module 20 through the second return air outlet 203 comes from outdoors, that is, the first ventilation module 20 introduces outdoor air into the room and regulates the indoor air. For example, indoor air and outdoor air can be introduced into the first ventilation module 20 at the same time. The above three adjustment modes can meet the different needs of users and enhance user experience.

[0140] Optionally, the first ventilation module 20 also includes: a second air guide device, arranged above the first return air outlet 202 and the second return air outlet 203, for opening or closing the circulation channel 2102 between the first return air outlet 202 and the second return air outlet 203 and the first fan 204; when the first ventilation module 20 is connected to the third ventilation module 50, the second air guide device is closed, and the airflow of the third ventilation module 50 flows into the first ventilation module 20, passes through the first fan 204, and is blown out from the first air outlet 201.

[0141] When the first ventilation module 20 is connected to the third ventilation module 50, the second air guide device closes the flow channel 2102 between the first and second return air ports 202, 203, and the first fan 204. This allows the airflow from the third ventilation module 50 to flow into the first ventilation module 20 and then be blown out of the first air outlet 201 via the first fan 204. In other words, the air conditioned by the third ventilation module 50 can be blown out directly from the first ventilation module 20 or conditioned again by the first ventilation module 20 before being blown out. This further expands the adjustment modes of the air handling device.

[0142] In some embodiments, when the first ventilation module 20 is connected to the third ventilation module 50, the first air guide device 206 at the first return air outlet 202 and the second air guide device at the second return air outlet 203 can be closed to prevent the flow of external air from mixing with the airflow from the third ventilation module 50. In actual applications, closing the circulation channel 2102 by the second air guide device can not only prevent the flow of external air from mixing with the airflow from the third ventilation module 50, but also prevent part of the airflow from the third ventilation module 50 from flowing downward and being stored in the air duct between the first return air outlet 202 and the second return air outlet 203, thereby affecting the flow rate of the airflow blown out from the first air outlet 201.

[0143] Optionally, the casing 10 also includes: a first air duct 205, connecting the first air outlet 201, the first return air outlet 202 and the second return air outlet 203; a second air duct 404, connecting the second air outlet 401 and the third return air outlet 402; wherein, the third air duct 504 is located between the first air duct 205 and the second air duct 404, and can selectively connect the first air duct 205 and the second air duct 404.

[0144] The first air duct 205 is the air duct of the first ventilation module 20, the second air duct 404 is the air duct of the second ventilation module 40, and the third air duct 504 is the air duct of the third ventilation module 50. The third air duct 504 is located between the first air duct 205 and the second air duct 404, so that the third air duct 504 can be selectively connected to the first air duct 205 and the second air duct 404 to achieve multiple air conditioning modes.

[0145] The embodiment of the present disclosure also provides an air treatment device, including: a casing 10, which is constructed with a first air duct 205, a second air duct 404 and a third air duct 504 arranged side by side; a first fan 204, which is arranged in the first air duct 205, for blowing out the air in the first air duct 205; a second fan 403, which is arranged in the second air duct 404, for blowing out the air in the second air duct 404; a full heat exchange core 503, which is arranged in the third air duct 504; wherein the third air duct 504 is selectively connected to the first air duct 205, and the third air duct 504 is selectively connected to the second air duct 404.

[0146] The air treatment device provided in the embodiment of the present disclosure can be selectively connected with the first air duct 205 and the second air duct 404 through the third air duct 504, so that the air treatment device has multiple ventilation adjustment modes and adjusts the air flowing through the full heat exchange core 503. In this way, it can not only meet the user's various ventilation needs, but also improve the efficiency of adjusting the indoor environment and enhance the user experience.

[0147] Optionally, the return air outlet of the third air duct 504 is higher than the return air outlet of the first air duct 205 , and / or the return air outlet of the third air duct 504 is higher than the return air outlet of the second air duct 404 .

[0148] In this way, the airflow in the third air duct 504 flows into the first air duct 205 or the second air duct 404, avoiding airflow interference with the return air outlet of the first air duct 205 or the return air outlet of the second air duct 404, and then blows out from the first air outlet 201 of the first air duct 205 or the second air outlet 401 of the second air duct 404.

[0149] Optionally, the return air outlet of the third air duct 504 is lower than the first air outlet 201 of the first air duct 205 and the second air outlet 401 of the second air duct 404. In this way, air flows in from the lower end and blows out from the higher end, thereby enhancing the circulation of indoor air and improving the conditioning effect on the indoor environment.

[0150] Optionally, the casing 10 includes an indoor panel 101 and an outdoor panel 102; the third air duct 504 includes at least two return air vents, which are respectively provided on the indoor panel 101 and the outdoor panel 102, so that indoor air or outdoor air flows into the third air duct 504.

[0151] In this way, the third air duct 504 can introduce indoor air through the return air vent located on the indoor panel 101 for air conditioning, thereby achieving the purpose of regulating the indoor air itself. Outdoor air can be introduced into the third air duct 504 through the return air vent located on the outdoor panel 102 for conditioning, thereby regulating the indoor air. In addition, using outdoor air to regulate indoor air helps improve efficiency and save resources.

[0152] Exemplarily, the two return air vents are a fourth return air vent 501 located on the indoor panel 101 and a fifth return air vent 502 located on the outdoor panel 102 .

[0153] Optionally, the air treatment device also includes: a first partition 507, which is vertically arranged in the casing 10 and facing the first air duct 205; the first partition 507 is configured with a first ventilation port 505; a first slide 509, which is slidably connected to the first partition 507, for opening or closing the first ventilation port 505; and a first drive assembly 511, which is connected to the first slide 509, for driving the first slide 509 to slide along the first partition 507.

[0154] The first slide 509 is driven by the first driving component 511 to slide along the first partition 507, thereby opening the first vent 505, that is, connecting the first air duct 205 and the third air duct 504, or closing the first vent 505, that is, blocking the connection between the first air duct 205 and the third air duct 504, thereby realizing the selective connection between the first ventilation module 20 and the third ventilation module 50.

[0155] Optionally, the first vent 505 is located at the bottom of the first partition 507. In this way, the air in the third air duct 504 can flow from the first vent 505 into the first air duct 205, and the airflow flowing into the first air duct 205 can flow upward from the bottom to the first fan 204, and then be blown out from the first air outlet 201 through the first fan 204.

[0156] Optionally, the air treatment device also includes: a second partition 512, which is vertically arranged in the casing 10 and facing the second air duct 404; the second partition 512 is constructed with a second ventilation port 506; a second slide 514, which is slidably connected to the second partition 512 to open or close the second ventilation port 506; and a second drive assembly 516, which is connected to the second slide 514 to drive the second slide 514 to slide along the second partition 512.

[0157] The second slide 514 is driven to slide along the second partition 512 by the second driving component 516, thereby opening the second vent 506, that is, connecting the second air duct 404 and the third air duct 504, or closing the second vent 506, that is, blocking the connection between the second air duct 404 and the third air duct 504, thereby realizing the selective connection between the second ventilation module 40 and the third ventilation module 50.

[0158] Optionally, the second vent 506 is located at the bottom of the second partition 512. In this way, the air in the third air duct 504 can flow from the second vent 506 into the second air duct 404, and the airflow flowing into the second air duct 404 can flow upward from the bottom to the second fan 403, and then be blown out from the second air outlet 401 through the second fan 403.

[0159] Optionally, the first vent 505 and the second vent 506 are arranged opposite and offset. That is, the first vent 505 and the second vent 506 are located on either side of the full heat exchange core 503. In this way, whether the third ventilation module 50 is connected to the first ventilation module 20 or the second ventilation module 40, it is ensured that the air flowing into the third ventilation module 50 is processed by the full heat exchange core 503 before flowing out to the corresponding ventilation module.

[0160] Optionally, a first slide 508 is constructed at the edge of the first partition 507, and a first slide 509 is slidably arranged in the first slide 508; wherein, the board surface of the first slide 509 is provided with a first rack structure 510, and a first drive component 511 is arranged on the first partition 507. The first drive component 511 is connected by a gear rack meshing to drive the first slide 509 to slide up and down in the first slide 508 to open or close the first vent 505.

[0161] The first slideway 508 can not only limit the position of the first slide plate 509 but also guide the first slide plate 509 when the first driving assembly 511 drives the first slide plate 509 to slide.

[0162] Alternatively, the first drive assembly 511 may comprise a motor and a gear, the gear being meshed with the first rack structure 510. The motor drives the gear to rotate, thereby driving the first rack structure 510 to move linearly, thereby driving the first slide 509 to slide. The first drive assembly 511 can drive the first slide 509 to slide upward and downward by rotating the motor in the forward and reverse directions, thereby opening or closing the first vent 505.

[0163] Optionally, the first rack structure 510 is vertically arranged to adapt to the up and down sliding of the first slide plate 509.

[0164] Optionally, a second slide 513 is constructed on the edge of the second partition 512, and the second slide 514 is slidably arranged in the second slide 513; wherein, the board surface of the second slide 514 is provided with a second rack structure 515, and the second drive component 516 is arranged on the second partition 512, and the second drive component 516 is connected by a gear rack meshing to drive the second slide 514 to slide up and down in the second slide 513 to open or close the second vent 506.

[0165] The second slideway 513 not only limits the position of the second slide plate 514 , but also guides the second slide plate 514 when the second driving assembly 516 drives the second slide plate 514 to slide.

[0166] Alternatively, the second drive assembly 516 may comprise a motor and a gear, the gear being meshed with the second rack structure 515. The motor drives the gear to rotate, thereby driving the second rack structure 515 to move linearly, thereby driving the second slide 514 to slide. The second drive assembly 516 can drive the second slide 514 to slide upward and downward by rotating the motor forward and reverse, thereby opening or closing the second vent 506.

[0167] Optionally, the second rack structure 515 is vertically arranged to adapt to the up and down sliding of the second slide plate 514.

[0168] Optionally, the housing 10, the first partition 507, and the second partition 512 enclose the third air duct 504; the second partition 512 is arranged parallel to and opposite the first partition 507. The first partition 507 faces the first ventilation module 20, and the second partition 512 faces the second ventilation module 40. The parallel and opposite arrangement of the first partition 507 and the second partition 512 facilitates installation and improves the overall structural stability of the third ventilation module 50 and the third air duct 504.

[0169] Optionally, the air treatment device also includes: a purification device, which can be raised and lowered in the first air duct 205 and is located on the air inlet side of the first fan 204; a second air guide device, which is provided above the first return air outlet 202 and the second return air outlet 203, and is used to open and close the circulation channel 2102 between the first return air outlet 202 and the second return air outlet 203 and the first fan 204; when the first air duct 205 is connected to the third air duct 504, the purification device can be lowered and drive the second air guide device to close. After being lowered, the purification module 2092 and the first fan 204 define a circulation space. The air in the third air duct 504 flows into the circulation space, passes through the first fan 204, and is blown out from the first air outlet 201.

[0170] When the first air duct 205 is connected to the third air duct 504, the purification module 2092 descends and drives the second air guide device to close. In this way, the airflow from the third air duct 504 directly passes through the circulation space, flows into the first fan 204, and is then blown out from the first air outlet 201. This can not only prevent the airflow from the third air duct 504 from being reduced in volume when passing through the purification device, but also prevent the airflow from the third air duct 504 from being purified by the filter layer of the full heat exchange core 503 in the third air duct 504, without having to pass through the purification device again.

[0171] In addition, by closing the circulation channel 2102 between the first return air outlet 202 and the second return air outlet 203 and the first fan 204 through the second air guide device, the airflow from the third air duct 504 can be prevented from flowing to the first return air outlet 202 and the second return air outlet 203, thereby reducing the airflow flow into the first fan 204.

[0172] Optionally, the purification device includes: a first fixing frame 2091, which is provided with a purification module 2092, the first fixing frame 2091 includes a plurality of vertically arranged ribs 2093, and the ribs 2093 are located on one side of the first fixing frame 2091; the second air guide device includes: a second fixing frame 2101, which is provided on the casing 10 and encloses a circulation channel 2102, and the air flow flowing into the first ventilation module 20 from the first return air inlet 202 and the second return air inlet 203 flows through the circulation channel 2102 and is blown out from the first air outlet 201 by the first fan 204; the second fixing frame 2101 is located between the first return air inlet 202 and the first fan 204, and is located below the first fixing frame 2091; the guide The air plate 2103 is rotatably connected to the inner side of the second fixed frame 2101; the guide member 2104 is rotatably connected to the outer side of the second fixed frame 2101 and is arranged in a linkage with the air guide plate 2103. The guide member 2104 is arranged to interfere with the rib 2093. When the rib 2093 moves downward, the guide member 2104 rotates counterclockwise and drives the air guide plate 2103 to rotate to close the circulation channel 2102, preventing the airflow from the first return air inlet 202 and the second return air inlet 203 from flowing into the first fan 204. When the rib 2093 moves upward, the guide member 2104 rotates clockwise and drives the air guide plate 2103 to rotate to open the circulation channel 2102. In this way, the rib 2093 of the first fixed frame 2091 moves up and down, thereby driving the air guide plate 2103 of the second air guide device to open or close the circulation channel 2102, and can also drive the purification module 2092 to move up and down through the first fixed frame 2091.

[0173] Optionally, the first ventilation module 20 also includes: a purification module 2092, which is arranged on the first fixed frame 2091 and moves synchronously with the first fixed frame 2091; when the first fixed frame 2091 rises to the first position, the second air guide device opens the circulation channel 2102, and the air from the first return air port 202 and / or the second return air port 203 can flow into the purification module 2092 through the circulation channel 2102, and the purified air is blown out through the first fan 204; when the first fixed frame 2091 descends to the second position, the second air guide device closes the circulation channel 2102, and the purification module 2092 and the first fan 204 define a circulation space, and the air from the third ventilation module 50 flows into the circulation space and is blown out through the first fan 204.

[0174] In this embodiment, the first position can be a specific position or a range. Specifically, the first position can be understood as the position of the second air guide device's air deflector 2103 just after it opens, and any area above this position can be considered the first position. Alternatively, the first position can be understood as the position of the second air guide device's air deflector 2103 when it is fully opened. When the first position is the position of the second air guide device's air deflector 2103 when it is fully opened, the first position is positioned adjacent to or close to the first fan 204.

[0175] In addition, the second position in this embodiment is a specific position, that is, the second position is the position when the air guide plate 2103 of the second air guide device is completely closed.

[0182] Optionally, it further includes: a second driving device, which is arranged on the outside of the mounting frame 2121 and connected to the first fixing frame 2091, and is used to drive the first fixing frame 2091 to move up and down.

[0183] Optionally, the second driving device includes: a second motor 2111, which is arranged on the mounting frame 2121; a gear element, which is transmission-connected to the second motor 2111; a rack element 2113, which is meshed with the gear element and connected to the first fixed frame 2091; when the second motor 2111 rotates forward, the second motor 2111 drives the rack element 2113 to move downward through the gear element, thereby driving the first fixed frame 2091 to descend; when the second motor 2111 rotates reversely, the second motor 2111 drives the rack element 2113 to move upward through the gear element, thereby driving the first fixed frame 2091 to rise.

[0184] In this embodiment, there are two second driving devices, which are symmetrically arranged on both sides of the mounting frame 2121. In this way, when driving the first fixing frame 2091 to rise and fall, it can not only improve the stability during the lifting process, but also ensure the structural stability of the first ventilation module 20.

[0185] Optionally, it further includes: a heat exchanger 2131, which is arranged in the mounting frame 2121 and located on the air inlet side of the fan to exchange heat with the air flowing into the fan.

[0186] The heat exchanger 2131 exchanges heat with the air flowing into the first fan 204, thereby achieving the purpose of regulating the temperature and humidity of the air, thereby enabling the air treatment device to meet different needs and improve user experience.

[0187] Optionally, the mounting frame 2121 , the first fixing frame 2091 and / or the second fixing frame 2101 are all frame 2061 structures, and the first fixing frame 2091 is adapted to the second fixing frame 2101 .

[0188] The mounting frame 2121, first fixing frame 2091, and / or second fixing frame 2101 are all constructed from a frame 2061 structure, facilitating the installation of the first motor 2081, purification module 2092, and third drive device. Furthermore, the alignment of the first fixing frame 2091 with the second fixing frame 2101 not only enhances the overall aesthetics of the ventilation module, but also allows the second fixing frame 2101 to support the first fixing frame 2091 when the first fixing frame 2091 is lowered to its second position, i.e., when the first fixing frame 2091 is lowered to the second fixing frame 2101.

[0189] Optionally, the side of the mounting frame 2121 is configured with an air outlet portion adapted to the air outlet side of the fan; and / or the side of the second fixing frame 2101 is configured with an air inlet grille.

[0191] An air inlet grille is configured on the side of the second fixing frame 2101 so that air flows from the outside into the ventilation module.

[0192] The air treatment device provided in the embodiment of the present disclosure includes a housing 10 and a ventilation module provided in the above embodiment. The ventilation modules are arranged in the housing 10, and the housing 10 is constructed with an air outlet and a return air outlet that are compatible with the air outlet part and the air inlet grille of the ventilation module.

[0193] The ventilation module in this embodiment may be the first ventilation module 20 in the air treatment device.

[0194] Combine Figures 20 to 24 As shown, the embodiment of the present disclosure also provides a humidifying device 30 for an air treatment device, including: a box body 301, in which an atomizing assembly 302 is provided, and the atomizing assembly 302 is used to atomize the water in the box body 301; a box cover 303, which is arranged on the top of the box body 301 and is constructed with a mist outlet cavity 304, and the mist outlet cavity 304 is arranged corresponding to the atomizing assembly 302, so that the water mist atomized by the atomizing assembly 302 enters the mist outlet cavity 304 and flows out from the mist outlet cavity 304.

[0195] The humidifying device 30 provided in the embodiment of the present disclosure is used to atomize the water in the box 301 through the atomizing component 302. The atomized water mist can be stored in the mist outlet chamber 304 so as to be separated from the water in the box 301. The water mist in the mist outlet chamber 304 flows out to humidify the air, thereby achieving the purpose of the air treatment device to regulate the air humidity.

[0196] Optionally, the box cover 303 is further configured with a water inlet cavity 305 , which is used to connect to a water inlet pipe 306 to allow water to enter the box body 301 ; wherein the water inlet cavity 305 and the mist outlet cavity 304 are independently provided and both communicate with the box body 301 .

[0197] The water inlet pipe 306 is connected to an external water source to achieve the purpose of letting water into the box body 301.

[0198] By independently arranging the water inlet chamber 305 and the mist outlet chamber 304, the inlet water flow can be prevented from affecting the water mist atomized by the atomizing assembly 302, thereby helping to ensure the mist output of the humidifying device 30 and further improving the humidification effect of the air flow blown out from the air outlet.

[0199] Optionally, the top of the mist outlet chamber 304 is higher than the top of the water inlet chamber 305 , so that the atomized water mist is stored at the top of the mist outlet chamber 304 and discharged from the top of the mist outlet chamber 304 .

[0200] The mist outlet chamber 304 and the water inlet chamber 305 are both connected to the box body 301. Since the top of the mist outlet chamber 304 is higher than the top of the water inlet chamber 305, on the one hand, there is a certain space for storing water mist, and on the other hand, it can prevent the rising water level in the humidifier 30 from affecting the water mist.

[0201] In addition, the atomized water mist moves upward to the mist outlet chamber 304 , which helps the water mist to be discharged from the top of the mist outlet chamber 304 .

[0202] Optionally, the device further comprises: a water mist channel component 307 , which is in communication with the mist outlet cavity 304 and is used to guide the water mist in the mist outlet cavity 304 out.

[0203] The water mist channel assembly 307 directs the water mist to a predetermined location, such as the air outlet. Furthermore, the water mist channel assembly 307 allows the humidifier 30 to be installed in any desired location within the housing 10, thereby increasing the flexibility of the humidifier 30 installation and avoiding the need for significant structural adjustments to the air handling system to install the humidifier 30.

[0204] In addition, the humidifying device 30 can be located at the bottom of the housing 10, and the water mist is guided to the air outlet located at the top of the housing 10 through the water mist channel assembly 307. In this way, not only the humidification function is achieved, but also the humidifying device 30 is prevented from being installed on the top of the housing 10 and suspended, thereby improving the stability of the humidifying device 30.

[0205] Optionally, the water mist channel assembly 307 is a tubular structure, for example, a square tube or a round tube; and the mist outlet 3071 is located on the side of the first air outlet 201, so that the water mist discharged from the mist outlet 3071 is blown out into the room for humidification through the air flow flowing out of the first air outlet 201.

[0206] Mist outlet 3071 is located to the side of first air outlet 201. When air is blown out of first air outlet 201, it mixes with the mist flowing out of mist outlet 3071 and is blown out into the room to humidify the air. Furthermore, placing mist outlet 3071 to the side of first air outlet 201 prevents mist from forming a humid environment in the air duct and affecting other components.

[0207] Optionally, the edge of the first air outlet 201 is configured with a hem 2012, and the mist outlet 3071 of the water mist duct assembly 307 extends through the hem 2012 to securely connect to the first air outlet 201. This facilitates installation of the mist outlet 3071 and secures the water mist duct assembly 307. Especially when air flows through the mist outlet 3071, the mist outlet 3071 of the water mist duct assembly 307 extends through the hem 2012, allowing the first air outlet 201 and the mist outlet 3071 to form a similar, integrated design, thereby enhancing the stability of the mist outlet 3071 of the water mist duct assembly 307.

[0208] Optionally, the plane where the mist outlet 3071 of the water mist channel assembly 307 is located is perpendicular to the plane where the first air outlet 201 is located. This helps to improve the installation stability between the mist outlet 3071 and the first air outlet 201.

[0209] Optionally, the system further comprises a solenoid valve 308 located in the water inlet chamber 305 and connected to the water inlet pipe 306 for controlling the on-off of the water flow. In this way, the on-off of the water flow can be controlled by the solenoid valve 308, thereby improving the degree of automation.

[0210] Optionally, the humidifier 300 further includes a filter element 309 located in the water inlet chamber 305 and connected to the water outlet of the solenoid valve 308 for filtering the water flowing into the water inlet chamber 305. Thus, the filter element 309 filters the incoming water flow to improve the cleanliness of the atomized water mist, thereby preventing the water mist from flowing out into the room and adversely affecting the environmental quality, and also preventing impurities in the water flow from adversely affecting other components of the humidifier 30.

[0211] Optionally, the filter element 309 includes: a receiving frame, which is a frame 2061 structure and is detachably connected to the solenoid valve 308; and a filter body, which is disposed in the receiving frame and is detachable.

[0212] The detachable connection of the accommodating frame to the solenoid valve 308 and the detachable connection of the filter body to the accommodating frame not only facilitates disassembly and assembly, but also facilitates replacement and maintenance of a component in the accommodating frame and the filter body, thereby helping to reduce usage costs and improve user experience.

[0213] Optionally, it further includes: a water level detector 310, which is provided on the box cover 303 and located on the side of the water inlet chamber 305 for detecting the water level.

[0214] The water level detector 310 detects the water level in the box 301. If the water level is lower than a first preset level, a signal is sent to open the water flow through the water inlet pipe 306 via the solenoid valve 308 to add water. If the water level is higher than a second preset level, a signal is sent to shut off the water flow through the water inlet pipe 306 via the solenoid valve 308 to prevent the water in the box 301 from overflowing or affecting the use of other components and the water mist in the water mist chamber.

[0215] Optionally, the water level detector 310 is detachably connected to the tank cover 303 and is installed on one side of the solenoid valve 308 .

[0216] Optionally, a hollow chamber 3011 is constructed at the bottom of the housing 301. This chamber houses an electrical control board, which is connected to the solenoid valve 308 and the water level detector 310. This not only enhances the overall aesthetics of the humidifier 30, but also protects the electrical control board from water and mist when installed. The electrical control board is connected to the solenoid valve 308 and the water level detector 310, as well as to the electrical control system of the air handling unit, to automatically control the operation of the humidifier 30 and enhance the user experience.

[0217] The air treatment device provided in the embodiments of the present disclosure includes the humidifier 30 provided in the above embodiments. Specifically, the device comprises: a housing 10 having a first air outlet 201; the humidifier 30 disposed within the housing 10 and comprising a water tank and a water mist channel assembly 307. The water mist channel assembly 307 connects the water tank and the first air outlet 201 to transport the atomized water mist in the water tank to the first air outlet 201 for blowing out.

[0218] The air treatment device provided by the embodiment of the present disclosure not only guides the water mist formed in the water tank to the first air outlet 201 for blowing out through the water mist channel assembly 307, but also enables the installation position of the humidifier 30 in the casing 10 to be unrestricted, thereby improving the installation flexibility of the humidifier 30, and further improving the installation efficiency and reducing costs.

[0219] In addition, the humidifying device 30 can be located at the bottom of the housing 10, and the water mist can be directed to the first air outlet 201 located at the upper part of the housing 10 through the water mist channel assembly 307. In this way, not only the humidification function is achieved, but also the humidifying device 30 can be prevented from being installed on the top of the housing 10 and suspended, thereby improving the stability of the humidifying device 30.
