The control element is electrically connected to the driving mechanism 130, and is configured to control the driving mechanism 130 to drive the switch valve 123 to open the water outlet 121a when the water level detection device 140 detects that the water in the water tank 124a is lower than the preset water level, and to control the driving mechanism 130 to drive the switch valve 123 to close the water outlet 121a when the water level detection device 140 detects that the water in the water tank 124a is higher than the preset water level.

In the present embodiment, the entire housing 110 may have a square, rectangular, cylindrical, irregular shape, or the like. The air duct 113 may be formed by the entire inner cavity of the housing 110. The housing 110 may be integrally formed, or may be formed by splicing an air inlet volute and an air outlet volute. Usually, a fan is further disposed in the air duct 113 to drive an air flow from the air inlet 111 into the air duct 113 and out of the air outlet 112.

The number of the air outlets 112 is at least one, and the number of the air outlets 112 may be selected according to requirements, for example, one, two, or three. The air outlet 112 of the casing 110 is provided with a guiding sealing structure, and the guiding sealing structure is in sealing fit with an air outlet arranged on the casing 200 of the indoor unit of the air conditioner. The shapes of the air inlet 111 and the air outlet 112 may be selected according to actual requirements, and may be, for example, circular, rectangular, and long-strip shapes.

The water tank 124a may be formed by a mounting bracket 124 of the humidifying assembly 120, or the like, as long as the water tank 124a is formed on the humidifying assembly 120. It will be appreciated that the area of the water tank 124a should be smaller than the cross-sectional area of the air duct 113, so that after the humidifying element 122 is mounted on the water tank 124a, the air flow can pass through the humidifying element 122 to achieve humidification. The shape of the water tank 124a may be a ring shape, a circular shape, a rectangular shape, etc., and is not particularly limited herein. The depth of the water tank 124a may be selected and designed according to actual requirements, and is not particularly limited herein. The humidifying assembly 120 may be fixedly installed in the housing 110, or may be detachably installed in the housing 110, as long as the humidifying assembly 120 is located in the air duct 113. Optionally, to facilitate filling of the water tank 121, the humidifying assembly 120 is removably or movably mounted to the housing 110. The water tank 121 may be additionally provided with a water inlet which may be provided at an upper side of the water tank 121 so that a user can add water from above the water tank 121, of course, the water inlet may be provided at other positions.

The humidifying element 122 may include a humidifying cotton, a wet film, or an ultrasonic atomizing element, and only needs to be able to adsorb the water in the water tank 124a or atomize the water in the water tank 124a, so that the air flow in the air duct 113 can be effectively humidified when passing through the humidifying element 122. The humidifying element 122 may be directly placed in the water tank 124a, or may be fixedly installed in the water tank 124 a. The water tank 121 may be disposed above the water tank 124a, and the water tank 121 may be installed in the water tank 124a or may be installed on other structures. The water tank 121 may be flush with the water tank 124a or lower than the water tank 124a, so long as the water outlet 121a of the water tank 121 is located above the water tank 124a or flush with the water tank 124 a. In this way, the water in the water tank 121 can naturally flow into the water tank 124a through the water outlet 121a by the action of gravity. The water outlet 121a may be located in the water tank 124a or above the water tank 124a, and the water outlet 121a may be disposed at the bottom of the water tank 121 or at a side wall of the water tank 121, so that only water can be directly added to the water tank 124 a. When the on-off valve 123 is opened, the water in the water tank 121 naturally flows into the water tank 124a through the action of gravity to realize the water adding of the water tank 124a, and when the on-off valve 123 is closed, the water in the water tank 121 does not flow out, so that the water can be stopped in time when the water tank 124a does not need to add water.

The switching valve 123 may rotate to open or close the water outlet 121a, and may also move to open or close the water outlet 121 a. In order to make the effect of opening and closing the valve 123 and opening and closing the water outlet 121a better. Alternatively, the switching valve 123 is a valve core such that the valve core moves up and down to open or close the water outlet port 121 a. The valve core is made of a sealing material such as rubber to ensure the sealing between the valve core and the water tank 121. The driving mechanism 130 may specifically include a motor and a transmission member, and the motor and the transmission member are sequentially connected to the switch valve 123 in a transmission manner, so as to drive the switch valve 123 to open the water outlet 121a or close the water outlet 121 a. Through actuating mechanism 130 drive ooff valve 123 and open or close, compare and set up ooff valve 123 as the solenoid valve, can avoid the influence that the electromagnetism became invalid and bring, its control is more reliable and more stable, and life is longer.

The water level detection device 140 is used to detect the water level in the water tank 124a, and the water level detection device 140 may be of various types, such as a floating ball type water level detection structure, an ultrasonic type water level detection structure, an electro-optical type water level detection structure, and the like. It is only necessary to detect whether the water in the water tank 124a reaches the preset water level and transmit the signal indicating that the water in the water tank 124a does not reach the preset water level and the signal indicating that the water reaches the preset water level to the control element. The control unit specifically includes a control main board, and the control main board is configured to receive a signal from the water level detecting device 140 and control the driving mechanism 130 to operate according to the signal. When the water level detection device 140 detects that the water in the water tank 124a is lower than the preset water level, a water supplement signal is sent to the control element, and the control element controls the driving mechanism 130 to drive the switch valve 123 to open the water outlet 121a, so as to supplement water to the water tank 124 a. When the water level detection device 140 detects that the water in the water tank 124a reaches or is higher than the preset water level, a water turn-off signal is sent to the control element, and the control element controls the driving mechanism 130 to drive the switch valve 123 to close the water outlet 121a, so as to stop adding water to the water tank 124a, thereby preventing the water tank 124a from overflowing due to the overhigh water level in the water tank 124a, and further preventing the air treatment device 100 from generating an electric leakage phenomenon.

The air treatment device 100 of the present invention has a water tank 124a disposed in the air duct 113, such that the humidifying element 122 is disposed in the water tank 124a, the water tank 121 is provided with a water outlet 121a for supplying water to the water tank 124a, the water level detection device 140 is used to detect the water level in the water tank 124a, and the control element is used to control the driving mechanism 130 to drive the switch valve 123 to open the water outlet 121a when the water level detection device 140 detects that the water in the water tank 124a is lower than a preset water level, and to control the driving mechanism 130 to drive the switch valve 123 to close the water outlet 121a when the water level detection device 140 detects that the water in the water tank 124a is higher than the preset water level. Thus, while the humidification function of the air duct 113 of the air processing device 100 is realized, the driving mechanism 130 is controlled by the water level detection device 140 and the control element to drive the switch valve 123 to open or close the water outlet 121a, so that the control is more accurate and reliable, the water tank 124a is effectively ensured to be timely filled with water in the absence of water, and the water outlet 121a of the water tank 121 is timely stopped when the water level in the water tank 124a is high.

In an embodiment, referring to fig. 6 to 11, the water level detecting device 140 includes a float 141 and a magnetic induction switch 142, the float 141 is installed in the water tank 124a, the magnetic induction switch 142 is electrically connected to the control element, and the control element is configured to control the driving mechanism 130 to drive the switch valve 123 to open the water outlet 121a when the magnetic induction switch 142 senses that the float 141 is lower than a predetermined water level, and control the driving mechanism 130 to drive the switch valve 123 to close the water outlet 121a when the magnetic induction switch 142 senses that the float 141 is higher than the predetermined water level.

In the present embodiment, the float 141 is made of a material having a density less than that of water, so that the float 141 can float on the water surface and rise and fall with the water level in the water tank 124 a. The float 141 may be a floating ball or a float. It is understood that the float 141 should be magnetized so that whether the float 141 is lower or higher than the preset water level is judged by switching the magnetic circuit of the float 141 and the magnetic induction switch 142. In one embodiment, the float 141 is a magnetic float 141. In another embodiment, a magnetic member is provided on the float 141. The magnetic member may be a permanent magnet. The magnetic member may be specifically disposed above the float 141 to facilitate timely judgment of whether the water level in the water tank 124a reaches a preset water level. In practice, the magnetic induction switch 142 is installed on the housing 110 and corresponds to a preset water level of the water tank 124 a. Therefore, when the water level in the water tank 124a is lower than the preset water level, the float 141 is located at the bottom of the water tank 124a, so that the magnetic induction switch 142 is turned off, and the control element receives the water replenishing signal, thereby controlling the driving mechanism 130 to drive the switch valve 123 to open the water outlet 121a so as to add water into the water tank 124 a. When the water level in the water tank 124a is equal to or higher than the preset water level, the magnetic induction switch 142 is turned on, the control element receives the water-off signal, and the control element controls the driving mechanism 130 to drive the switch valve 123 to close the water outlet 121a, so as to stop adding water into the water tank 124 a. The predetermined water level is lower than the highest water level that the water tank 124a can reach, so that the overflow phenomenon can be prevented. The water level monitoring in the water tank 124a is realized by adopting the mode of the floater 141 and the magnetic induction switch 142, and the water level monitoring device is good in effect, low in cost and easy to realize.

Specifically, as shown in fig. 6, 7, 9, and 11 to 14, the air treatment device 100 further includes a float housing 150 installed in the water tank 124a, the float housing 150 defines a float chamber communicating with the water tank 124a, and the float 141 is provided in the float chamber so as to float up and down.

In a preferred embodiment, the control unit is further configured to emit a water shortage signal to the water tank 121 when the magnetic sensing switch 142 senses that the float 141 is below the preset water level for more than a preset time and/or controls the driving mechanism 130 to drive the on-off valve 123 to open for more than a preset time. The water shortage signal of the water tank 121 can be specifically a buzzer, a voice prompt, an indicator light and the like, and only a user needs to be prompted to add water into the water tank 121. The preset time may be specifically 2 minutes. Specifically, the control element further comprises a timing module for recording the time when the magnetic induction switch 142 senses that the float 141 is lower than the preset water level and the driving mechanism 130 drives the switch valve 123 to open. The float 141 is still lower than the preset water level when the water replenishing duration is longer than the preset time, indicating that there is a water shortage in the water tank 121, and further causing the control element to send a water tank shortage signal to remind the user to add water. So, when making water tank 121 lack of water, the user can in time know and add water, and control is more intelligent, promotes the user and uses experience. In practical applications, when the humidification function of the air processing module 100 is turned on, the driving mechanism 130 is operated to open the switch valve 123 and add water to the water tank 124a, the control unit detects whether the magnetic inductive switch 142 and the float 141 are connected, and if the magnetic inductive switch 142 is not connected within a preset time, it indicates that the water tank 121 is empty, and sends a water tank empty signal. When the magnetic switch 142 is turned on, indicating that the water tank 124a is full, the driving mechanism 130 is operated to drive the switch valve 123 to close the water outlet 121a, and the water tank 121 stops adding water to the water tank, and the cycle is repeated.

In an embodiment, as shown in fig. 13 and 14, the magnetic induction switch 142 includes a first magnetic control 142a and a second magnetic control 142b, the first magnetic control 142a is installed in the housing 110 and corresponds to a preset high water level setting of the water tank 124a, the second magnetic control 142b is installed in the housing 110 and corresponds to a preset low water level setting of the water tank 124a, the preset high water level is higher than the preset low water level, and the control element is configured to control the driving mechanism 130 to drive the switch valve 123 to close the water outlet 121a when the first magnetic control 142a senses that the float 141 is at the preset high water level, and control the driving mechanism 130 to drive the switch valve 123 to open the water outlet 121a when the second magnetic control 142b senses that the float 141 is at the preset low water level.

Compared with the magnetic induction switch 142 which is only arranged at the preset water level, the magnetic induction switch can accurately receive the signal that the floater 141 is lower than the preset water level and the time that the floater 141 is at the preset low water level, thereby reducing the control error and improving the control precision. The preset high water level may be the same as or different from the preset water level. It can be understood that, the control element is used for controlling the driving mechanism 130 to drive the switch valve 123 to close the water outlet 121a when the first magnetic control 142a senses that the float 141 is located at the preset high water level, and controlling the driving mechanism 130 to drive the switch valve 123 to open the water outlet 121a when the second magnetic control 142b senses that the float 141 is located at the preset low water level, so that the water level in the water tank 124a is always between the preset low water level and the preset high water level, thereby preventing the water level in the water tank 124a from being too low or too high, meeting the humidification requirement and avoiding the overflow phenomenon. In practical applications, when the humidification function of the air processing module 100 is turned on, the driving mechanism 130 acts to open the switch valve 123 and add water to the water tank 124a, and the control element detects whether the first magnetic control 142a is connected to the float 141, and if the first magnetic control 142a is not connected within a preset time, it indicates that the water tank 121 is empty of water, and sends a water tank empty signal. When the first magnetic control 142a is turned on, indicating that the water tank 124a is full, the driving mechanism 130 operates to drive the switch valve 123 to close the water outlet 121a, and the water tank 121 stops adding water to the water tank. Meanwhile, whether the second magnetic control 142b is turned on or not is judged, if yes, the driving mechanism is controlled to operate to open the on-off valve 123 and add water into the water tank 124a, and if not, the driving mechanism 130 operates to drive the on-off valve 123 to close the water outlet 121a, and the process is repeated.

The switching valve 123 is configured to move to open or close the water outlet 121 a. The ejector rod 132 can convert the rotation of the driving motor 131 into the switching motion of the switch valve 123, the switch of the switch valve 123 is realized through the driving motor 131 and the ejector rod 132, compared with the switch valve 123 which is directly controlled to be opened or closed through electromagnetism, the influence caused by the electromagnetic failure can be avoided, the control is more stable and reliable, and the service life is longer.

step S10, receiving a signal for starting a humidifying function;

step S20, controlling the driving mechanism 130 to open the on-off valve 123 according to the received signal for starting the humidification function, so as to add water into the water tank;

step S30, determining that the water level detection device 140 detects that the water in the water tank 124a is higher than a preset water level, controlling the driving mechanism 130 to drive the switch valve 123 to close the water outlet 121 a;

step S40, determining that the water level detection device 140 detects that the water in the water tank 124a is lower than a preset water level, controlling the driving mechanism 130 to drive the switch valve 123 to open the water outlet 121 a.

In this embodiment, the air processing apparatus 100 has a control component for receiving a signal and controlling other components to perform corresponding actions according to the signal. The signal to turn on the humidification function may be a signal sent to the air treatment device 100 by the user through a remote control, a key, a mobile phone APP, or the like. The signal for turning on the humidification function may also be a signal for turning on the humidification function of the air processing device 100 automatically according to the detected indoor humidity, and is not particularly limited herein. After the air treatment device 100 receives the signal for starting the humidification function, the control element controls the driving mechanism 130 to open the water outlet 121a of the water tank 121, so as to add water into the water tank 124a, thereby realizing the normal humidification function of the air treatment device 100.

When the water level detecting device 140 detects that the water in the water tank 124a is higher than the predetermined water level, it indicates that the water level in the water tank 124a is full, and if the water is continuously added, the water in the water tank 124a will overflow. Therefore, a water-off signal is sent to the control unit, and the control unit controls the driving mechanism 130 to drive the on-off valve 123 to close the water outlet 121a, so as to stop adding water into the water tank 124 a. When the water level detection device 140 detects that the water in the water tank 124a is lower than the preset water level, it represents that the water level in the water tank 124a is insufficient, and therefore, a water supplement signal is sent to the control element, and the control element controls the driving mechanism 130 to drive the switch valve 123 to open the water outlet 121a, so as to add water into the water tank 124 a. And then the control is more accurate and reliable, the water tank 124a is effectively ensured to be timely added with water when the water is short of water, and the water outlet 121a of the water tank 121 is timely stopped flowing when the water level in the water tank 124a is higher.

When the water level in the water tank 124a is equal to or higher than the preset water level, the magnetic induction switch 142 is communicated with the float magnetic circuit, the control element receives the water-off signal, and the control element controls the driving mechanism 130 to drive the switch valve 123 to close the water outlet 121a, so as to stop adding water into the water tank 124 a. The predetermined water level is lower than the highest water level that the water tank 124a can reach, so that the overflow phenomenon can be prevented. When the water level in the water tank 124a is lower than the preset water level, the float 141 is located at the bottom of the water tank 124a, so that the magnetic induction switch 142 is disconnected from the magnetic circuit of the float, and the control element receives the water replenishing signal, thereby controlling the driving mechanism 130 to drive the switch valve 123 to open the water outlet 121a so as to replenish water into the water tank 124 a.

When it is determined that the time when the magnetic inductive switch 142 senses that the float 141 is lower than the preset water level is longer than the preset time, that is, it is determined that the magnetic inductive switch 142 does not sense that the float 141 is higher than the preset water level within the preset time, it represents that the float in the water tank 124a is located at the bottom of the water tank for a long time.

Compared with the magnetic induction switch 142 which is only arranged at the preset water level, the magnetic induction switch can accurately receive the signal that the floater 141 is lower than the preset water level and the time that the floater 141 is at the preset low water level, thereby reducing the control error and improving the control precision.

And the time for controlling the driving mechanism 130 to drive the on-off valve 123 to open is determined to be longer than the preset time, which indicates that the water tank 121 is filled with water for too long time and the water level in the water tank 124a has not yet reached the preset water level. All indicate that the water tank is short of water. And then the control element sends out a water shortage signal of the water tank to remind a user of adding water.
