[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] The following describes an air treatment device 100 ( Figure 3-Figure 5 The arrow direction in FIG. 1 is the air flow direction). The air treatment device 100 can be used alone, or it can be used in an air conditioning device as a part of the air conditioning device.

[0041] Reference Figure 1 and Figure 2 According to the air treatment device 100 of the first embodiment of the present invention, the working modes of the air treatment device 100 include indoor purification mode, fresh air mode and exhaust mode. The air treatment device 100 includes: a first shell 1, a first fan component 2, a purification component 3 for purifying air and a control component.

[0042] Specifically, a first air inlet 1111, a first air outlet 122 and an outdoor vent 1121 are formed on the first housing 1. The first air inlet 1111 and the first air outlet 122 are both connected to the indoor room, and the outdoor vent 1121 is connected to the outdoor room. The first fan assembly 2 and the purification assembly 3 are both arranged in the first housing 1, and the control assembly can control the opening and closing of the first air inlet 1111 and the outdoor vent 1121.

[0043] Optionally, the first air inlet 1111 and the outdoor vent 1121 may be disposed on opposite sides of the first housing 1 , and the first air outlet 122 may be disposed above the first air inlet 1111 .

[0044] Reference Figure 3 When the air treatment device 100 is in the indoor purification mode, the control component controls the first air inlet 1111 to be opened and the outdoor vent 1121 to be closed, and the first fan component 2 drives the indoor air to enter the first shell 1 from the first air inlet 1111. The indoor airflow entering the first shell 1 is purified by the purification component 3 and then discharged from the first air outlet 122, thereby purifying the indoor air and improving the indoor air quality.

[0045] Optionally, the purification component 3 may have any one or more functions of filtering and intercepting particulate matter, removing formaldehyde, and removing odor.

[0046] Reference Figure 5When the air handling device 100 is in the fresh air mode, the control component controls the outdoor vent 1121 to open and controls the first air inlet 1111 to close, and the first fan component 2 drives the outdoor air to enter the first shell 1 from the outdoor vent 1121, and finally be discharged into the room from the first air outlet 122, so that outdoor fresh air can be introduced into the room, reducing the indoor carbon dioxide content and improving the indoor air quality.

[0047] Optionally, when the air treatment device 100 is in the fresh air mode, the outdoor air entering the first shell 1 from the outdoor vent 1121 can be purified by the purification component 3 and then discharged into the room through the first air outlet 122. In this way, the outdoor air entering the room can be purified, and the quality of the air introduced from the outside to the room can be improved, thereby further improving the indoor air quality.

[0048] Optionally, when the air treatment device 100 is in the fresh air mode, the outdoor air entering the first shell 1 from the outdoor vent 1121 may be directly discharged into the room through the first air outlet 122 without being purified by the purification component 3 .

[0049] Reference Figure 4 When the air treatment device 100 is in the exhaust mode, the control component controls the outdoor vent 1121 and the first air inlet 1111 to be opened, and the first fan component 2 drives the indoor air to enter the first shell 1 from the first air inlet 1111 and be discharged from the outdoor vent 1121, so that the turbid air in the room can be directly discharged to the outside.

[0050] It is understandable that the purification function of the purification component 3 is always limited, and some harmful gases in the indoor air cannot be purified and removed by the purification component 3. For example, harmful gases such as sulfur dioxide and carbon monoxide in the indoor air may not be purified by the purification component 3. At this time, the indoor air quality can be further improved by directly discharging the turbid air in the room to the outside.

[0051] For another example, when there is odor in the indoor air and the purification component 3 cannot remove it, the indoor odorous air can also be discharged to the outside through the exhaust mode, so that the indoor odor can be quickly eliminated.

[0052] Optionally, the first fan assembly 2 may include only one fan, thereby simplifying the structure of the first fan assembly 2 and reducing the number of components.

[0053] The above three working modes (indoor purification mode, fresh air mode and exhaust mode) of the air treatment device 100 can be automatically controlled.

[0054] Automatic control of the indoor purification mode can be carried out as follows: whether to enter the indoor purification mode can be determined by detecting whether the particulate matter content or formaldehyde content in the indoor air exceeds the standard. If the particulate matter content or formaldehyde content exceeds the standard, the air treatment device 100 enters the indoor purification mode. When it is detected that the particulate matter content or formaldehyde content in the indoor air drops to the standard range, the air treatment device 100 can automatically exit the indoor purification mode.

[0055] For example, when the purification component 3 has the function of filtering and intercepting particles, if the particle content of the indoor air is detected to be excessive, the air treatment device 100 enters the indoor purification mode, thereby reducing the particle content in the indoor air. After the air treatment device 100 enters the indoor purification mode, if the indoor air particle content drops to within the standard range, the air treatment device 100 can automatically exit the indoor purification mode.

[0056] For another example, when the purification component 3 has the function of removing formaldehyde, if the formaldehyde content of the indoor air is detected to be excessive, the air treatment device 100 enters the indoor purification mode, thereby reducing the formaldehyde content in the indoor air. After the air treatment device 100 enters the indoor purification mode, if the formaldehyde content of the indoor air drops to within the standard range, the air treatment device 100 can automatically exit the indoor purification mode.

[0057] For another example, when the purification component 3 has the functions of filtering and intercepting particulate matter and removing formaldehyde at the same time, if any one of the particulate matter content and formaldehyde content of the indoor air is detected to be excessive, the air treatment device 100 enters the indoor purification mode, thereby reducing the particulate matter and / or formaldehyde content in the indoor air. After the air treatment device 100 enters the indoor purification mode, if the indoor air particulate matter content and formaldehyde content are both reduced to within the standard range, the air treatment device 100 can automatically exit the indoor purification mode.

[0058] The automatic control of the fresh air mode can be performed as follows: whether to enter the fresh air mode can be determined by detecting whether the carbon dioxide content of the indoor air exceeds the standard. When the carbon dioxide content of the indoor air is detected to exceed the standard, the air treatment device 100 automatically enters the fresh air mode, thereby introducing outdoor fresh air into the room, thereby reducing the indoor carbon dioxide content. After the air treatment device 100 enters the fresh air mode, if the indoor carbon dioxide content drops to within the standard range, the air treatment device 100 can automatically exit the fresh air mode.

[0059] The automatic control of the exhaust mode can be performed as follows: whether to enter the exhaust mode can be determined by detecting whether the content of pollutants (such as sulfur dioxide, carbon monoxide, odor molecules, etc.) that cannot be purified and removed by the purification component 3 in the indoor air exceeds the standard. When it is detected that the content of pollutants that cannot be purified and removed by the purification component 3 in the indoor air exceeds the standard, the air treatment device 100 automatically enters the exhaust mode, thereby discharging the indoor dirty air to the outdoors, thereby reducing the content of pollutants that cannot be purified and removed by the purification component 3 in the indoor air, and of course, the content of other substances in the indoor air can also be reduced at the same time (such as the above-mentioned carbon dioxide, formaldehyde, particulate matter, etc.). After the air treatment device 100 enters the exhaust mode, if the content of pollutants that cannot be purified and removed by the purification component 3 in the indoor air drops to within the standard range, the air treatment device 100 can automatically exit the exhaust mode at this time.

[0060] Of course, the above three working modes of the air treatment device 100 can also be controlled manually, for example, the user can select any one of the three working modes by pressing a button. After the air treatment device 100 enters a certain working mode, the user can exit the mode by pressing a button, or the air treatment device 100 automatically exits after entering a certain working mode and running for a set time.

[0061] The switching of the above working modes of the air treatment device 100 can be controlled individually; or the switching control can be coordinated with each other according to the control program, thereby realizing one-click air freshening. For example, the user only needs to press the fresh air button to automatically enter the above control program.

[0062] For example, a corresponding control program may be preset in the air treatment device 100, so that the above three working modes are switched and controlled in coordination with each other according to the control program. For example, the control program may be as follows: after the air treatment device 100 is turned on, it may first detect whether the indoor carbon dioxide content exceeds the standard. If the indoor carbon dioxide content exceeds the standard, the air treatment device 100 is controlled to enter the fresh air mode. If the indoor carbon dioxide content does not exceed the standard, the indoor particulate matter content is detected; if the indoor particulate matter content exceeds the standard, the air treatment device 100 is controlled to enter the indoor purification mode. If the indoor particulate matter content does not exceed the standard, it is detected whether the content of pollutants in the indoor air that cannot be purified and removed by the purification component 3 exceeds the standard; if the content of pollutants in the indoor air that cannot be purified and removed by the purification component 3 exceeds the standard, the air treatment device 100 is controlled to enter the exhaust mode. If the content of pollutants in the indoor air that cannot be purified and removed by the purification component 3 does not exceed the standard, the air treatment device 100 may be automatically shut down.

[0063] Therefore, when the air treatment device 100 is working, it is possible to conveniently and automatically switch between working modes such as indoor purification mode, fresh air mode and exhaust mode, so as to keep the indoor air in an excellent state.

[0064] According to the air treatment device 100 of the embodiment of the present invention, by arranging the first air inlet 1111, the first air outlet 122 and the outdoor vent 1121 on the first housing 1 and arranging the purification component 3 in the first housing 1, and controlling the opening and closing of the first air inlet 1111 and the outdoor ventilation through the control component, the flow direction of the airflow can be changed, so that the automatic switching of the indoor purification mode, the fresh air mode and the exhaust mode can be conveniently performed, so that the indoor air is kept in a good state. In addition, the cost is low and the space occupied is small.

[0065] According to some embodiments of the present invention, referring to Figure 3-Figure 5 The first fan assembly 2 includes a centrifugal fan 21, which can be shared by the above three working modes of the air treatment device 100. The centrifugal fan 21 has a large wind resistance capacity, can adapt to complex and changing air duct structures, and can improve the performance of the whole machine.

[0066] According to some embodiments of the present invention, referring to Figure 2-Figure 5 The control component includes: a first driving mechanism 62, a first baffle 61, a second driving mechanism 64 and a second baffle 63. The first baffle 61 can open and close the first air inlet 1111, and the first driving mechanism 62 is connected to the first baffle 61 to drive the first baffle 61 to move. The first air inlet 1111 can be opened and closed by the movement of the first baffle 61. The second baffle 63 can open and close the outdoor vent 1121. The second driving mechanism 64 is connected to the second baffle 63 to drive the second baffle 63 to move. The outdoor vent 1121 can be opened and closed by the movement of the second baffle 63. As a result, the structure of the control component is simple, and it is convenient to control the opening and closing of the first air inlet 1111 and the outdoor vent 1121, so as to facilitate the control of the switching between different working modes of the air treatment device 100.

[0067] Optionally, refer to Figure 2 The first driving mechanism 62 is connected to the first baffle 61 to drive the first baffle 61 to rotate, thereby the first air inlet 1111 can be conveniently opened and closed by the rotation of the first baffle 61; and / or the second driving mechanism 64 is connected to the second baffle 63 to drive the second baffle 63 to rotate, thereby the outdoor vent 1121 can be conveniently opened and closed by the rotation of the second baffle 63. The first driving mechanism 62 and the second driving mechanism 64 can both be motors.

[0068] In some embodiments of the present invention, reference Figure 3 and Figure 4When the first baffle 61 is in a position to open the first air inlet 1111, the first baffle 61 is received in the first shell 1, thereby reducing the extra space occupied by the first baffle 61 and making the structure of the whole machine compact.

[0069] According to some embodiments of the present invention, referring to Figure 2-Figure 5 The first shell 1 defines a first chamber 11 and a second chamber 12 separated from each other, the purification component 3 is arranged in the second chamber 12, the second chamber 12 can be located above the first chamber 11, the first chamber 11 and the second chamber 12 are connected through a connecting port 121, the first air inlet 1111 and the outdoor vent 1121 are both formed on the side wall of the first chamber 11, the first air outlet 122 is formed on the side wall of the second chamber 12, and the control component can control the opening and closing of the connecting port 121.

[0070] Among them, when the air treatment device 100 is in the indoor purification mode, the control component controls the communication port 121 to be opened, at this time the first chamber 11 and the second chamber 12 are connected, the first fan assembly 2 drives the indoor air to enter the first chamber 11 from the first air inlet 1111, and enter the second chamber 12 through the communication port 121, and after being purified by the purification component 3, it is discharged to the room through the first air outlet 122. When the air treatment device 100 is in the fresh air mode, the control component controls the communication port 121 to be opened, at this time the first chamber 11 and the second chamber 12 are connected, the first fan assembly 2 drives the outdoor air to enter the first chamber 11 from the outdoor vent 1121, and enter the second chamber 12 through the communication port 121, and after being purified by the purification component 3, it is discharged to the room through the first air outlet 122. When the air treatment device 100 is in the exhaust mode, the control component controls the communication port 121 to be closed, and the first fan assembly 2 drives the indoor air to enter the first chamber 11 from the first air inlet 1111 and be discharged to the outside from the outdoor vent 1121.

[0071] Therefore, by defining two first chambers 11 and second chambers 12 in the first shell 1 that can be connected through the connecting port 121, and controlling the connecting port 121 to be opened and closed by the control component, in the exhaust mode, the first air outlet 122 can be disconnected from the first air inlet 1111 and the first air outlet 122 can be disconnected from the outdoor vent 1121, so that smooth exhaust can be achieved and the indoor turbid air flow can be prevented from flowing back into the room through the first air outlet 122.

[0072] In some embodiments of the present invention, reference Figure 2-Figure 5The control component includes: a first driving mechanism 62, a first baffle 61, a second driving mechanism 64 and a second baffle 63. The first baffle 61 can open and close the first air inlet 1111. The first driving mechanism 62 is connected to the first baffle 61 to drive the first baffle 61 to move. The first air inlet 1111 can be opened and closed by the movement of the first baffle 61. The second driving mechanism 64 is connected to the second baffle 63 to drive the second baffle 63 to move. The second baffle 63 can open and close the outdoor vent 1121 and the connecting port 121. The outdoor vent 1121 and the connecting port 121 can be opened and closed by the movement of the second baffle 63. Among them, the first driving mechanism 62 and the second driving mechanism 64 can both be motors.

[0073] Among them, the second baffle 63 has a first position, a second position and a third position. When the second baffle 63 is in the first position, the second baffle 63 closes the outdoor ventilation port 1121 and opens the connecting port 121; when the second baffle 63 is in the second position, the second baffle 63 opens the outdoor ventilation port 1121 and closes the connecting port 121; when the second baffle 63 is in the third position, the second baffle 63 opens the outdoor ventilation port 1121 and opens the connecting port 121.

[0074] Specifically, when the air treatment device 100 is in the indoor purification mode (refer to Figure 3 ), the first baffle 61 opens the first air inlet 1111, the second baffle 63 is in the first position, the second baffle 63 closes the outdoor vent 1121 and opens the connecting port 121; when the air treatment device 100 is in the exhaust mode (refer to Figure 4 ), the first baffle 61 opens the first air inlet 1111, the second baffle 63 is located at the second position, the second baffle 63 opens the outdoor vent 1121 and closes the connecting port 121; when the air treatment device 100 is in the fresh air mode (refer to Figure 5 ), the first baffle 61 closes the first air inlet 1111, the second baffle 63 is located at the third position, and the second baffle 63 opens the outdoor ventilation port 1121 and the connecting port 121.

[0075] Thus, the structure of the control component is simple, and it is convenient to control the opening and closing of the first air inlet 1111, the outdoor vent 1121 and the connecting port 121, so as to facilitate the switching between different working modes of the control processing device. In addition, the opening and closing of the connecting port 121 and the outdoor vent 1121 can be realized by the movement of a second baffle 63, which further makes the overall structure simple and convenient to control.

[0076] In other embodiments of the present invention, the control assembly includes: a first driving mechanism 62, a first baffle 61, a second driving mechanism 64, a second baffle 63, a third driving mechanism and a third baffle. Among them, the first baffle 61 can open and close the first air inlet 1111, the first driving mechanism 62 is connected to the first baffle 61 to drive the first baffle 61 to move, and the first air inlet 1111 can be opened and closed by the movement of the first baffle 61. The second baffle 63 can open and close the outdoor vent 1121, the second driving mechanism 64 is connected to the second baffle 63 to drive the second baffle 63 to move, and the outdoor vent 1121 can be opened and closed by the movement of the second baffle 63. The third baffle can open and close the connecting port 121, the third driving mechanism is connected to the third baffle to drive the third baffle to move, and the connecting port 121 can be opened and closed by the movement of the third baffle. Thus, the structure of the control component is simple, and it is convenient to control the opening and closing of the first air inlet 1111, the outdoor vent 1121 and the communication port 121, so as to facilitate the switching between different working modes of the control processing device. Among them, the first drive mechanism 62, the second drive mechanism 64 and the third drive mechanism can all be motors.

[0077] According to some optional embodiments of the present invention, referring to Figure 3-Figure 5 A movable partition 65 is provided in the first chamber 11. The partition 65 and the first fan assembly 2 cooperate with each other to separate the first chamber 11 into an air inlet area 111 and an air outlet area 112. The first air inlet 1111 is formed on the side wall of the air inlet area 111. The air outlet area 112 is suitable for being connected with the second chamber 12 through a connecting port 121. The outdoor vent 1121 can be connected with one of the air inlet area 111 and the air outlet area 112 through the movement of the partition 65.

[0078] When the air handling device 100 is in the exhaust mode, the partition 65 is located at the first separation position, and the outdoor vent 1121 is connected with the air outlet area 112. At this time, the first fan assembly 2 drives the indoor air from the first air inlet 1111 into the air inlet area 111 of the first chamber 11, and then flows into the air outlet area 112 through the first fan assembly 2, and finally is discharged to the outside from the outdoor vent 1121. When the air handling device 100 is in the fresh air mode, the partition 65 is located at the second separation position, and the outdoor vent 1121 is connected with the air inlet area 111. At this time, the first fan assembly 2 drives the outdoor air from the outdoor vent 1121 into the air inlet area 111 of the first chamber 11, and then flows into the air outlet area 112 through the first fan assembly 2, and then flows into the second chamber 12 through the connecting port 121, and is purified by the purification assembly 3 and discharged to the room.

[0079] Therefore, by providing a movable partition 65 in the first chamber 11, and by the partition 65 and the first fan assembly 2 cooperating with each other to separate the first chamber 11 into an air inlet area 111 and an air outlet area 112, and by the movement of the partition 65 to connect the outdoor vent 1121 with one of the air inlet area 111 and the air outlet area 112, the air inlet area 111 and the air outlet area 112 of the first fan assembly 2 can be separated, thereby preventing mixed air, improving the working efficiency of the first fan assembly 2, and ensuring smooth switching of the above three working modes of the air treatment device 100.

[0080] Optionally, refer to Figure 3 When the air treatment device 100 is in the indoor purification mode, the partition 65 can be located at the first partition position. Since the outdoor vent 1121 is closed at this time, the outdoor vent 1121 is not connected to the air inlet area 111 and the air outlet area 112. Therefore, the movement of the partition 65 is simple and convenient to control.

[0081] Optionally, the partition 65 may also be located at other positions except the first partition position and the second partition position, as long as the partition 65 and the first fan assembly 2 cooperate to separate the first chamber 11 into the air inlet area 111 and the air outlet area 112 without blocking the first air inlet 1111 and the connecting port 121.

[0082] Optionally, the partition 65 can be rotatably connected to the first fan assembly 2. Thus, the movement of the partition 65 is simple and convenient to control the movement of the partition 65. For example, the control assembly can include a fourth drive mechanism 66, and the partition 65 is driven to move by the fourth drive mechanism 66. For example, the fourth drive mechanism 66 can be a motor.

[0083] In some optional embodiments of the present invention, referring to Figure 2-Figure 5 The control component may include: a first driving mechanism 62, a first baffle 61, a second driving mechanism 64 and a second baffle 63. The first baffle 61 can open and close the first air inlet 1111. The first driving mechanism 62 is connected to the first baffle 61 to drive the first baffle 61 to move. The first air inlet 1111 can be opened and closed by the movement of the first baffle 61. The second driving mechanism 64 is connected to the second baffle 63 to drive the second baffle 63 to move. The second baffle 63 can open and close the outdoor vent 1121 and the connecting port 121. The outdoor vent 1121 and the connecting port 121 can be opened and closed by the movement of the second baffle 63. Among them, the first driving mechanism 62 and the second driving mechanism 64 can both be motors.

[0084] Among them, the second baffle 63 has a first position, a second position and a third position. When the second baffle 63 is in the first position, the second baffle 63 closes the outdoor ventilation port 1121 and opens the connecting port 121; when the second baffle 63 is in the second position, the second baffle 63 opens the outdoor ventilation port 1121 and closes the connecting port 121; when the second baffle 63 is in the third position, the second baffle 63 opens the outdoor ventilation port 1121 and opens the connecting port 121, and the second baffle 63, the partition 65 and the first fan assembly 2 cooperate together to separate the first chamber 11 into an air inlet area 111 and an air outlet area 112.

[0085] Specifically, when the air treatment device 100 is in the indoor purification mode (refer to Figure 3 ), the first baffle 61 opens the first air inlet 1111, the second baffle 63 is in the first position, the second baffle 63 closes the outdoor vent 1121 and opens the connecting port 121, the partition 65 and the first fan assembly 2 cooperate to separate the first chamber 11 into the air inlet area 111 and the air outlet area 112; when the air treatment device 100 is in the exhaust mode (refer to Figure 4 ), the first baffle 61 opens the first air inlet 1111, the second baffle 63 is in the second position, the second baffle 63 opens the outdoor vent 1121 and closes the connecting port 121, the partition 65 and the first fan assembly 2 cooperate to separate the first chamber 11 into the air inlet area 111 and the air outlet area 112; when the air treatment device 100 is in the fresh air mode (refer to Figure 5 ), the first baffle 61 closes the first air inlet 1111, the second baffle 63 is located at the third position, the second baffle 63 opens the outdoor vent 1121 and the connecting port 121, and the second baffle 63, the partition 65 and the first fan assembly 2 cooperate to separate the first chamber 11 into an air inlet area 111 and an air outlet area 112.

[0086] Thus, the structure of the control component is simple, and it is convenient to control the opening and closing of the first air inlet 1111, the outdoor vent 1121 and the connecting port 121, so as to facilitate the switching between different working modes of the control processing device. In addition, the opening and closing of the connecting port 121 and the outdoor vent 1121 can be realized by the movement of a second baffle 63, which further makes the overall structure simple and convenient to control.
