[0036] Reference below Figure 1-Figure 6 An air treatment device 100 according to an embodiment of the present invention is described.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The air treatment device 100 according to an embodiment of the present invention includes: a shell 1, the shell 1 is provided with a fresh air channel 11, the shell 1 is also provided with a fresh air inlet 12 and a fresh air outlet 13 connected with the fresh air channel 11, the fresh air inlet 12 is suitable for connecting with the outdoor environment, the fresh air outlet 13 is suitable for connecting with the indoor environment, and the fresh air inlet 12 and the fresh air outlet 13 are both configured to have an open state and a closed state.

[0038] The air treatment device 100 also includes: a filter assembly 2 and a fan 3. The filter assembly 2 is arranged in the fresh air passage 11 and between the fresh air inlet 12 and the fresh air outlet 13; the fan 3 is arranged in the fresh air passage 11. The air treatment device 100 has a fresh air mode. In the fresh air mode, the fresh air inlet 12 and the fresh air outlet 13 are both in an open state, and the fan 3 works to drive the outdoor air into the fresh air passage 11 through the fresh air inlet 12, and passes through the filter assembly 2 in the fresh air passage 11 to filter dust in the air, and finally enters the indoor environment through the fresh air outlet 13 to improve the indoor air quality. In some specific embodiments, the filter assembly 2 includes a HEPA net, and the outdoor air in the fresh air mode flows into the room after being filtered by the HEPA net.

[0039] The air treatment device 100 further includes: a sterilization module 4 , which is disposed in the fresh air passage 11 , and is configured to have an open state and a closed state, and releases sterilizing substances when the sterilization module 4 is in the open state.

[0040] Because the air treatment device 100 of the present invention is provided with a sterilization module 4 that can release sterilizing substances, the air treatment device 100 includes a fresh air sterilization mode and an internal sterilization mode.

[0041] In the fresh air sterilization mode, the fresh air inlet 12 and the fresh air outlet 13 are both in an open state, and the fan 3 operates to drive the outdoor air to enter the room through the fresh air inlet 12, the fresh air passage 11 and the fresh air outlet 13 in sequence. In addition, in the fresh air sterilization mode, the sterilization module 4 is in an open state, that is, the sterilization module 4 releases sterilizing substances in the fresh air passage 11, thereby sterilizing the air passing through the fresh air passage 11, thereby improving the safety of the fresh air.

[0042] In the internal sterilization mode, the fresh air outlet 13 is in a closed state and the sterilization module 4 is in an open state. At this time, the sterilization module 4 continuously releases sterilizing substances in the outer shell 1, and the fresh air outlet 13 is in a closed state to prevent the sterilizing substances from entering the room, so that the sterilizing substances can diffuse inside the outer shell 1 and the concentration of the sterilizing substances in the outer shell 1 can be increased, thereby sterilizing the structural surface inside the outer shell 1.

[0043] According to the air treatment device 100 of the embodiment of the present invention, the fresh air can be sterilized in the fresh air sterilization mode, thereby improving the quality of the fresh air, and the internal structure of the air treatment device 100 can be sterilized in the internal sterilization mode, thereby effectively improving the safety of the air treatment device 100.

[0044] In some specific embodiments, the sterilizing substance includes ozone. In some other embodiments, the sterilizing substance may also include charged ions and / or free radicals.

[0045] In some further embodiments, the sterilization module 4 is disposed at the top of the fresh air duct 11 , so that when the sterilization module 4 releases ozone, the ozone can fall naturally, which is beneficial to the diffusion of the sterilization substance.

[0046] In some embodiments, in the internal sterilization mode, the fresh air inlet 12 is closed and the fan 3 is running.

[0047] Through the above technical solution, in the internal sterilization mode, the fresh air inlet 12 is also in a closed state, which prevents the sterilizing substances in the housing 1 from being discharged to the outside through the fresh air inlet 12. That is to say, in the internal sterilization mode, the fresh air inlet 12 and the fresh air outlet 13 are both in a closed state, so that the sterilizing substances released by the sterilization module 4 are confined in the housing 1. As the sterilization module 4 continuously releases the sterilizing substances, the concentration of the sterilizing substances in the housing 1 is continuously increased, which effectively improves the efficiency of disinfection and sterilization of the internal structure. In the internal sterilization mode, the fan 3 rotates to diffuse the sterilizing substances in the housing 1, which improves the sterilization efficiency of the internal structure of the air treatment device 100.

[0048] In some specific embodiments, after the air handling device 100 completes the internal sterilization mode, the fresh air inlet 12 is opened so that ozone can be discharged to the outside through the fresh air inlet 12 to prevent sterilizing substances from contaminating the indoor air.

[0049] In some further embodiments, the fan 3 is configured to rotate forward and reverse, and when the fan 3 rotates forward, it can drive the air to flow from the fresh air inlet 12 to the fresh air outlet 13, and when the fan 3 rotates reversely, it can drive the air to flow from the fresh air outlet 13 to the fresh air inlet 12. After the air treatment device 100 completes the internal sterilization mode, the fresh air inlet 12 is opened first, then the fan 3 is reversed, and finally the fresh air outlet 13 is opened, so that the fan 3 drives the sterilization substance to be discharged to the outside through the fresh air inlet 12, thereby accelerating the discharge efficiency of the sterilization substance.

[0050] In some embodiments, the sterilizing substance includes ozone. Because higher concentrations of ozone may have an impact on the health of the user, the sterilization module 4 in the embodiment of the present invention is provided with multiple adjustment gears, and the release speeds of the sterilizing substances in the multiple adjustment gears are different, so that the speed at which the sterilization module 4 releases the sterilizing substance is controllable, thereby improving the safety of the air treatment equipment 100.

[0051] In some specific embodiments, the sterilization module 4 includes a first adjustment gear and a second adjustment gear, and the release rate of the sterilization substance in the first adjustment gear is greater than the release rate in the second adjustment gear. Because when the sterilization module 4 is in the first adjustment gear, the release rate of the sterilization substance is faster, and it is easy to produce ozone with an excessive concentration, so the sterilization module 4 in the first adjustment gear is intermittently turned on, that is, the sterilization module 4 stops running after running for a period of time in the first adjustment gear, and then runs for a period of time again after stopping for a period of time, and repeats the start and stop. When the sterilization module 4 is in the second adjustment gear, the release rate of the sterilization substance is slower, so that the generated ozone is kept at a safe concentration, so the sterilization module 4 is continuously turned on in the second adjustment gear.

[0052] In some embodiments, a first switch door 5 is provided at the fresh air inlet 12, and the first switch door 5 is movably provided on the outer shell 1 to enable the fresh air inlet 12 to switch between an open state and a closed state; a second switch door 6 is provided at the fresh air outlet 13, and the second switch door 6 is movably provided on the outer shell 1 to enable the fresh air outlet 13 to switch between an open state and a closed state.

[0053] Reference Figure 4 , Figure 5 and Figure 6 In some specific embodiments, the first switch door 5 is constructed as a flip door, the shape of the flip door is adapted to the cross section of the fresh air inlet 12, one end of the flip door is hinged to the inner wall of the fresh air inlet 12, the flip door can be rotated to block the fresh air inlet 12 so that the fresh air inlet 12 is in a closed state, and the flip door can also be rotated to be perpendicular to the cross section of the fresh air inlet 12 so that the fresh air inlet 12 is in an open state. The hinge shaft of the flip door is connected to the output shaft of the first motor, so that the first motor can drive the flip door to rotate to control the fresh air inlet 12 to be in an open state or a closed state.

[0054] The second switch door 6 is constructed as a shutter structure, with both ends of the blades hinged to the inner wall of the fresh air outlet 13 respectively, and the surface of each blade is respectively provided with a hinge seat hinged to the connecting rod. The hinge shaft of one of the blades is driven to rotate by the second motor to drive the other blades to operate in conjunction, so that the fresh air outlet 13 can be controlled to be in an open state or a closed state by the second motor.

[0055] In some embodiments, the housing 1 is further provided with an indoor air inlet 14 connected to the fresh air passage 11. The indoor air inlet 14 is configured to have an open state and a closed state, and the indoor air inlet 14 is suitable for connecting to the indoor environment. In the fresh air sterilization mode and the internal sterilization mode, the indoor air inlet 14 is in a closed state.

[0056] The air treatment device 100 includes an indoor air sterilization mode. In the indoor air sterilization mode, the fresh air inlet 12 is in a closed state, the indoor air inlet 14 and the fresh air outlet 13 are both in an open state, and the sterilization module 4 is in an open state. In the indoor air sterilization mode, the fan 3 drives the indoor air to enter the fresh air channel 11 through the indoor air inlet 14, and enter the room again through the fresh air outlet 13. In this process, the sterilization module 4 releases sterilization substances to sterilize the air entering the fresh air channel 11, thereby purifying the indoor air.

[0057] In some embodiments, the indoor air inlet 14 is disposed between the fresh air inlet 12 and the fan 3. A third switch door 7 is disposed at the indoor air inlet 14, and the third switch door 7 is movably disposed on the housing 1 to switch the indoor air inlet 14 between an open state and a closed state.

[0058] In some specific embodiments, the third switch door 7 is slidably disposed on the housing 1, and the third switch door 7 can slide to block the indoor wind inlet 14, so that the indoor wind inlet 14 is in a closed state, and the third switch door 7 can also slide to avoid the indoor wind inlet 14, so that the indoor wind inlet 14 is in an open state. A rack is provided on the third switch door 7, and the housing 1 is also provided with a third motor, and the output shaft of the third motor is connected to a gear, and the gear is meshed with the gear. The third motor can control the sliding of the third switch door 7 by driving the gear to rotate, so that the indoor wind inlet 14 can be controlled to be in an open state or a closed state.

[0059] Reference Figure 3 , Figure 5 and Figure 6 In some embodiments, the fan 3 is configured to rotate in only one direction, and when the fan 3 is in operation, the air is driven to flow in the direction of the fresh air outlet 13. The air treatment device 100 further includes: an exhaust passage 15 and a first switching door 8, wherein the inlet end of the exhaust passage 15 is located between the fan 3 and the fresh air outlet 13, and the outlet end of the exhaust passage 15 is adapted to communicate with the outdoor environment, and the first switching door 8 cooperates with the exhaust passage 15 to enable or disable the exhaust passage 15.

[0060] The air handling equipment 100 has an exhaust state. In the exhaust state, the fresh air outlet 13 is in a closed state, the indoor air inlet 14 is in an open state, and the exhaust duct 15 is in a conducting state. The fan 3 works to allow indoor air to enter the fresh air duct 11 through the indoor air inlet 14. Because the fresh air outlet 13 is in a closed state, the inlet end of the exhaust duct 15 is located between the fan 3 and the fresh air outlet 13, so that air enters the exhaust duct 15 and is discharged to the outside through the exhaust duct 15.

[0061] Through the above technical solution, the fan 3 is configured to rotate in only one direction, thereby reducing the cost of the fan 3. The air treatment device 100 also has an exhaust state, so that the air treatment device 100 can exhaust indoor dirty air to the outside, thereby improving the practicality of the air treatment device 100.

[0062] In some specific embodiments, the first switching door 8 is located at the inlet end of the exhaust passage 15 .

[0063] Through the above technical solution, the first switching door 8 is arranged at the inlet end of the exhaust passage 15. When the first switching door 8 is in a closed state, air is prevented from flowing into the exhaust passage 15, thereby reducing wind loss.

[0064] In some specific embodiments, the first switching door 8 is rotatably disposed on the inner wall of the exhaust passage 15, and the first switching door 8 can be rotated to block the inlet end of the exhaust passage 15, and the first switching door 8 can also be rotated to the inside of the exhaust passage 15 to open the inlet end of the exhaust passage 15. The rotation shaft of the first switching door 8 is connected to the output shaft of the fourth motor, so that the fourth motor can control the rotation of the first switching door 8, thereby controlling the opening or closing of the inlet end of the exhaust passage 15.

[0065] In some embodiments, the fresh air inlet 12 is configured as the air outlet end of the exhaust channel 15, and the air treatment device 100 also includes a second switching door 9, which is located between the fresh air inlet 12 and the fan 3. In the exhaust state, the second switching door 9 is located between the fresh air inlet 12 and the filter assembly 2 to block the air from flowing toward the filter assembly 2.

[0066] That is, when the air handling device 100 is in the exhaust state, the indoor air inlet 14 and the fresh air inlet 12 are both in the open state, the fresh air outlet 13 is in the closed state, the first switching door 8 is in the open state, and the second switching door 9 blocks the fresh air inlet 12 from the fan 3. The fan 3 works so that the indoor air enters the fresh air passage 11 through the indoor air inlet 14, flows to the exhaust passage 15 after passing through the fan 3, and finally is discharged to the outside through the fresh air outlet 13.

[0067] Because the fan 3 is configured to rotate in only one direction, and the fan 3 drives the air to flow in the direction of the fresh air outlet 13 when it is running, that is, the fresh air inlet 12 and the indoor air inlet 14 are both located on the negative pressure side of the fan 3, the fresh air inlet 12 can be separated from the fan 3 by the second switching door 9 in the above technical solution, thereby blocking the outdoor air from flowing to the fan 3 through the fresh air inlet 12, thereby improving the discharge efficiency of the indoor air. At the same time, the fresh air inlet 12 is configured as the outlet end of the exhaust channel 15, and there is no need to set an exhaust outlet on the casing, which improves the utilization rate of the structure of the air treatment device 100 and reduces the cost of the air treatment device 100.

[0068] In both the fresh air sterilization mode and the indoor air sterilization mode, the second switching door 9 is located in the exhaust passage 15 to avoid air flow between the fresh air inlet 12 and the filter assembly 2. Because in both the fresh air sterilization mode and the indoor air sterilization mode, the fan 3 drives air to flow into the room through the fresh air outlet 13, and the exhaust passage 15 is idle, the second switching door 9 can be set in the exhaust passage 15, making full use of the internal space of the air treatment device 100.

[0069] In some specific embodiments, the second switching door 9 is slidably disposed between the fresh air passage 11 and the exhaust passage 15. When the second switching door 9 is located in the fresh air passage 11, the fresh air inlet 12 is blocked from the fan 3. When the second switching door 9 is located in the exhaust passage 15, the air flow between the fresh air inlet 12 and the filter assembly 2 is avoided. A rotatable screw rod 91 is disposed in the exhaust passage 15. The length direction of the screw rod 91 is parallel to the sliding direction of the second switching door 9. A screw rod sleeve matching the screw rod 91 is disposed on the second switching door 9. The screw rod 91 is connected to the output shaft of the fifth motor so that the fifth motor can drive the sliding of the second switching door 9, thereby controlling the second switching door 9 to slide to the fresh air passage 11 or the exhaust passage 15.

[0070] In some further embodiments, in the internal sterilization mode, the first switching door 8 and the second switching door 9 are moved to make the exhaust passage 15 at least partially open, so as to facilitate the diffusion of the sterilizing substance in the housing 1 and improve the sterilization efficiency.

[0071] Reference Figure 2 , Figure 3 and Figure 5 In some specific embodiments, a vertical partition plate 16 is provided in the housing 1, and the vertical partition plate 16 divides the space in the housing 1 into a first cavity 111 and a second cavity in the left-right direction. The fan 3 is provided at the top of the second cavity. An arc-shaped partition plate 17 that is shaped like the fan 3 is also provided in the second cavity, and the arc-shaped partition plate 17 divides the second cavity into a fan cavity 112 and an exhaust passage 15 in the up-down direction. A first through hole 161 connecting the first cavity 111 and the fan cavity 112 is provided at the top of the vertical partition plate 16, and a second through hole 162 connecting the first cavity 111 and the exhaust passage 15 is also provided at the bottom of the vertical partition plate 16. In other embodiments, the second through hole 162 may be defined between the bottom end of the vertical partition plate 16 and the bottom wall of the housing 1.

[0072] The first cavity 111 and the fan cavity 112 together define a fresh air channel 11. The fresh air inlet 12 is arranged at the lower side of the housing 1 and communicates with the first cavity 111, and the fresh air outlet 13 is arranged at the front side of the housing 1 and communicates with the fan cavity 112. The fan 3 is configured to drive air to flow toward the fresh air outlet 13. The filter assembly 2 and the sterilization module 4 are both arranged in the first cavity 111, and the indoor air inlet 14 is arranged at the upper side of the housing 1 and communicates with the first cavity 111.

[0073] The inlet end of the exhaust passage 15 is located between the fan 3 and the fresh air outlet 13, and a first switching door 8 is provided at the inlet end of the exhaust passage 15. A second switching door 9 is provided at the lower part of the exhaust passage 15, and the second switching door 9 is located above the second through hole 162. When the second switching door 9 is completely located in the exhaust passage 15, the air flow between the fresh air inlet 12 and the filter assembly 2 is avoided, and when the second switching door 9 is completely located in the first cavity 111, the fresh air inlet 12 is blocked from the fan 3.

[0074] In the fresh air sterilization mode, the fresh air inlet 12 and the fresh air outlet 13 are both in an open state, the indoor air inlet 14 is in a closed state, the first switching door 8 closes the inlet end of the exhaust passage 15, and the second switching door 9 is completely located in the exhaust passage 15. The fan 3 operates to drive the outdoor air to enter the room through the fresh air inlet 12, the filter assembly 2, the first through hole 161, the fan 3 and the fresh air outlet 13 in sequence. In addition, the sterilization module 4 is in an open state, and the sterilization module 4 releases sterilizing substances in the first cavity 111 to sterilize the fresh air.

[0075] In the internal sterilization mode, the fresh air inlet 12, the fresh air outlet 13 and the indoor air inlet 14 are all in a closed state, the first switching door 8 opens the inlet end of the exhaust passage 15, and the second switching door 9 is partially located in the first cavity 111 and the other part is located in the exhaust passage 15.

[0077] Reference Figure 7, according to the control method of the air treatment device 100 of the embodiment of the present invention, wherein the air treatment device 100 is the air treatment device 100 in the above technical solution. The control method comprises:

[0078] A mode instruction is received to determine which mode the air treatment device 100 enters.

[0079] When it is determined that the air treatment device 100 enters the fresh air sterilization mode, the fresh air inlet 12 and the fresh air outlet 13 are both controlled to be open, the fan 3 is controlled to operate, and the sterilization module 4 is turned on. The fan 3 operates to drive the outdoor air to enter the room through the fresh air inlet 12, the fresh air channel 11 and the fresh air outlet 13 in sequence. And the sterilization module 4 is in the open state, that is, the sterilization module 4 releases sterilization substances in the fresh air channel 11, thereby sterilizing the air passing through the fresh air channel 11, thereby improving the safety of the fresh air.

[0080] When it is determined that the air treatment device 100 enters the internal sterilization mode, the fresh air outlet 13 and the fresh air inlet 12 are both controlled to be closed, and the sterilization module 4 is controlled to be turned on. The fresh air outlet 13 and the fresh air inlet 12 are both in a closed state to prevent the leakage of the sterilizing substance, so that the sterilizing substance can diffuse inside the housing 1, and the concentration of the sterilizing substance in the housing 1 can be increased, thereby sterilizing the structure inside the housing 1.

[0081] According to the control method of the air treatment equipment 100 in an embodiment of the present invention, the air treatment equipment 100 can be controlled to enter a fresh air sterilization mode, thereby sterilizing the fresh air and improving the quality of the fresh air; the air treatment equipment 100 can also be controlled to enter an internal sterilization mode, thereby sterilizing the internal structure of the air treatment equipment 100, effectively improving the safety of the air treatment equipment 100.

[0082] In some embodiments, the sterilization module 4 includes a first adjustment gear and a second adjustment gear, and the release speed of the sterilization substance in the first adjustment gear is greater than the release speed in the second adjustment gear. Determining whether to enter the fresh air sterilization mode also includes determining the adjustment gear of the sterilization mode.

[0083] When it is determined that the sterilization module 4 is running at the first adjustment gear, the sterilization module 4 is controlled to be turned on intermittently. That is, after the sterilization module 4 runs at the first adjustment gear for a period of time, it stops running, stops running for a period of time, and then runs for a period of time again, and repeats the start and stop process.

[0084] When it is determined that the sterilization module 4 is in the second adjustment gear, the sterilization module 4 is controlled to be continuously turned on.

[0085] Because the sterilizing substance includes ozone, a higher concentration of ozone may have an impact on the health of the user. Therefore, the sterilization module 4 in the embodiment of the present invention is provided with two gears, and the release speeds of the sterilizing substances in the two gears are different, so that the speed at which the sterilization module 4 releases the sterilizing substance is controllable, thereby improving the safety of the air treatment equipment 100.

[0086] In some embodiments, after determining that the air handling device 100 enters the internal sterilization mode, the sterilization module 4 works for a first set time t1 and then turns off. After the sterilization module 4 turns off for a second set time t2, the air handling device 100 is controlled to exhaust air outdoors.

[0087] Through the above technical solution, after the sterilization module 4 works for the first set time t1, the sterilization substance inside the housing 1 reaches a predetermined concentration, and the sterilization continues for the second set time t2, thereby improving the sterilization efficiency of the internal structure of the housing 1. In addition, in this embodiment, after the sterilization of the internal structure of the housing 1 is completed, the sterilization substance is discharged to the outside, thereby avoiding the contamination of the indoor air by the sterilization substance.

[0088] In some further embodiments, the housing 1 is further provided with an indoor air inlet 14 connected to the fresh air duct 11. When the air handling device 100 is controlled to exhaust air outdoors, the fresh air inlet 12 is controlled to open first, and then the indoor air inlet 14 is controlled to open.

[0089] Through the above technical solution, when the air treatment device 100 is controlled to exhaust outdoors, the fresh air inlet 12 is controlled to open first, and then the indoor air inlet 14 is opened, so that the bactericidal substance in the outer shell 1 can be diffused to the outdoors first. When the air treatment device 100 is exhausted outdoors, the fan 3 rotates, so that the indoor air enters the outer shell 1 through the indoor air inlet 14, and carries the bactericidal substance in the air treatment device 100 to be discharged to the outdoors through the fresh air inlet 12, further reducing the possibility of the bactericidal substance entering the room.

[0090] In some embodiments, the fan 3 includes a first working gear and a second working gear, and the operating speed of the fan 3 in the first working gear is lower than the operating speed of the second working gear. After determining that the internal sterilization instruction has been entered, the fan 3 operates at the first working gear to increase the diffusion speed of the sterilizing substance in the housing 1 and improve the sterilization efficiency.

[0091] In some further embodiments, the fan 3 includes a first working gear and a second working gear, and the operating speed of the fan 3 in the first working gear is lower than the operating speed of the second working gear. After determining that the internal sterilization instruction has been entered, the fan 3 is controlled to operate at the first working gear when the sterilization module 4 is turned on. Before the fresh air inlet 12 is controlled to be opened and the indoor air inlet 14 is controlled to be opened, the fan 3 is controlled to operate at the second working gear.

[0092] In the above technical solution, after determining that the internal sterilization instruction has been entered, the sterilization module 4 is turned on to control the fan 3 to operate at the first working gear, that is, the fan 3 rotates at a lower speed to increase the diffusion speed of the sterilizing substance in the housing 1 and improve the sterilization efficiency. Before the fresh air inlet 12 is controlled to be opened and the indoor air inlet 14 is controlled to be opened, the fan 3 is controlled to operate at the second working gear to increase the impact of the negative pressure area of ​​the fan 3 on the indoor air inlet 14, thereby reducing the risk of leakage of the sterilizing substance from the indoor air inlet 14 when the indoor air inlet 14 is opened.
