Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

A water tank assembly 1 according to an embodiment of the present invention, which water tank assembly 1 may be used in an air treatment apparatus 100, is described below with reference to the accompanying drawings.

As shown in fig. 1 to 2, the water tank assembly 1 of the air treatment apparatus 100 according to the embodiment of the present invention may include: a make-up water tank 11, a working water tank 12, a water inlet pipe assembly 13, a heating device 14 and a steam valve 15.

Wherein, the water-filling water tank 11 can be provided with a water-containing chamber, and the water-filling water tank 11 can be provided with a water outlet communicated with the water-containing chamber. The working water tank 12 may define a water containing space, the working water tank 12 may be provided with a water inlet and a steam outlet which are communicated with the water containing space, and the steam outlet may be located above the water inlet. The two ends of the water inlet pipe assembly 13 can be respectively connected with the water inlet and the water outlet, so that the water supplementing water tank 11 can supplement water for the working water tank 12 through the water inlet pipe assembly 13.

Specifically, when the water tank assembly 1 is in operation, water may be contained within the water containing chamber of the refill water tank 11. Wherein the refill tank 11 may be connected to a water source (e.g., a faucet) through which water may be added to the refill tank 11. The water in the water holding chamber can enter the water inlet pipe assembly 13 through the water outlet and then enter the water replenishing tank 11 through the water inlet, so that water can be added into the water replenishing tank 11. Optionally, the height of the working water tank 12 may be higher than the height of the water-replenishing water tank 11, so that water in the water-replenishing water tank 11 may automatically enter the water-replenishing water tank 11 under the action of gravity, so that the water-replenishing mode of the water-replenishing water tank 11 is simpler, and a special water pump is not required to be arranged in the water-replenishing water tank 11, thereby reducing the energy consumption of the water tank assembly 1.

As shown in fig. 2, the heating device 14 may be provided on the working water tank 12, and the heating device 14 may heat water in the water containing space to form water vapor, which may be discharged through the vapor outlet. Specifically, when the water in the water replenishing tank 11 enters the working tank 12, the heating device 14 can heat the water in the water containing space, and the water is heated and gasified to form water vapor, so that the water vapor in the water containing space can be discharged through the vapor outlet. The water vapor discharged from the vapor outlet can enter the indoor space, thereby achieving the purpose of adjusting the humidity of the indoor air. Optionally, a plurality of steam outlets arranged at intervals may be arranged on the working water tank 12, so that the steam discharge efficiency of the working water tank 12 may be improved, and the air humidity adjusting efficiency of the water tank assembly 1 may be improved.

As shown in fig. 1 to 2, a steam valve 15 may be provided on the working water tank 12, and the water containing space may communicate with the external space when the steam valve 15 is in an open state. Specifically, when the water tank assembly 1 is operated, the steam valve 15 may be in a closed state, and water steam generated by heating water by the heating device 14 may be discharged through the steam outlet. When the pressure in the working water tank 12 needs to be regulated, the steam valve 15 can be regulated to an open state, and the water containing space is communicated with the external space at the moment, so that the pressure in the water containing space and the external pressure can be kept balanced, and the water inlet and the steam exhaust of the working water tank 12 can be ensured to be smoother.

For example, when the water vapor in the working water tank 12 is not normally discharged through the vapor outlet or the water vapor discharge rate in the working water tank 12 is slow, the air pressure in the water containing space is larger than the pressure in the water replenishing water tank 11 at this time. Under the effect of pressure, the water in the water replenishing water tank 11 can not enter the water replenishing water tank 11 through the water inlet pipe assembly 13, so that the phenomenon of dry heating of the heating device 14 can be caused, the service life of the heating device 14 can be shortened, and a relatively large potential safety hazard exists. At this time, the steam valve 15 can be adjusted to an open state, and the steam in the working water tank 12 can be discharged through the steam valve 15, so that the pressure difference between the water replenishing water tank 11 and the working water tank 12 can be reduced, and the water in the water replenishing water tank 11 can smoothly enter the working water tank 12, so that the water tank assembly 1 can normally operate.

For another example, when the pressure in the working water tank 12 is smaller than the pressure in the water replenishing water tank 11, the water inlet pipe assembly 13 may form a siphon effect between the water replenishing water tank 11 and the working water tank 12, the water replenishing water tank 11 continuously supplements water in the working water tank 12 under the action of negative pressure, and water in the working water tank 12 is directly discharged through the steam outlet, so that the water tank assembly 1 cannot normally operate. At this time, the steam valve 15 may be adjusted to an open state, and external air may be introduced into the working water tank 12 through the steam valve 15 to balance the pressure difference between the working water tank 12 and the makeup water tank 11. Thus, the water supply tank 11 can normally supply water to the working water tank 12. When the water level in the working water tank 12 reaches a level below the steam outlet, the water replenishing tank 11 may stop replenishing water towards the working water tank 12 and the heating device 14 starts heating the water in the water containing space to generate water steam.

According to the water tank assembly 1 of the air treatment apparatus 100 of the embodiment of the present invention, by providing the steam valve 15, the pressure in the working water tank 12 can be regulated by controlling the opening and closing of the steam valve 15, thereby ensuring that the water replenishment tank 11 can normally replenish water to the working water tank 12, and thus ensuring that the water tank assembly 1 can normally operate.

According to some embodiments of the present invention, the heating device 14 may be formed as a PTC (Positive Temperature Coefficient ) heating tube 14a disposed in the water containing space, and the PTC heating tube 14a has advantages of stable and reliable performance, high heating efficiency and long service life, thereby improving the efficiency of generating water vapor in the water tank assembly 1, and further improving the efficiency of adjusting the air humidity of the air treatment apparatus 100.

In some embodiments of the present invention, the water tank assembly 1 may further include a detection device (not shown) which may be communicatively connected to the PTC heating pipe 14a and the steam valve 15, respectively, and which may detect an operation current in the PTC heating pipe 14a, and which may be configured to control the opening or closing of the steam valve 15 according to the operation current of the PTC heating pipe 14a, thereby enabling automatic control of the steam valve 15, and may make the actual use of the water tank assembly 1 more convenient.

Specifically, the working current in the PTC heating tube 14a may be changed according to the water level change in the water containing space, and the level of the water in the water containing space may be determined according to the working current in the PTC heating tube 14 a. For example, when the PTC heating tube 14a is submerged in the water containing space, the operation current of the PTC heating tube 14a is maintained unchanged. When a portion of the PTC heating tube 14a is located above the liquid surface, the operating current of the PTC heating tube 14a may decrease as the liquid level in the water containing space decreases. When the operating current of the PTC heating pipe 14a is smaller than the set value, it is indicated that the liquid level in the water containing space is lowered to a position where the water replenishing tank 11 is required to replenish water. After a first set time interval, the water vapor in the water containing space is condensed and converted into condensed water, and the air pressure in the water containing space is reduced. At this time, the detecting device can control the steam valve 15 to be opened, and external air can enter the working water tank 12 through the steam valve 15 to balance the pressure difference between the working water tank 12 and the water replenishing water tank 11, thereby preventing the siphon effect between the water replenishing water tank 11 and the working water tank 12 and ensuring that the water tank assembly 1 can normally operate.

On the contrary, if the steam valve 15 is not opened, the pressure in the working water tank 12 is smaller and smaller than the pressure in the water replenishing water tank 11, and a siphon effect is formed between the water replenishing water tank 11 and the working water tank 12. Under the action of the siphon effect, the water replenishing water tank 11 continuously replenishes water into the working water tank 12, and water in the water replenishing water tank 11 is directly discharged through the steam outlet, so that the working water tank 12 cannot normally generate water steam, and the air treatment effect of the air treatment equipment is affected.

As shown in fig. 3, according to some embodiments of the present invention, the working water tank 12 may be provided with a mounting interface 1211, and the steam valve 15 may be provided with a fitting 151 screw-coupled with the mounting interface 1211. For example, the mounting interface 1211 may have internal threads therein, and the outer circumferential wall of the adapter 151 may have external threads thereon, such that the adapter 151 may be threadably engaged with the mounting interface 1211 when the steam valve 15 is assembled with the working water tank 12. Thus, by the above arrangement, the assembling method of the steam valve 15 can be made simpler, and the assembling efficiency of the steam valve 15 can be improved.

It will of course be appreciated that the manner of assembly between the steam valve 15 and the working water tank 12 is not limited thereto. For example, the steam valve 15 may be assembled with the working water tank 12 by a plug-in fit manner, the steam valve 15 may be connected with the working water tank 12 by a welding connection manner, and the assembly manner between the steam valve 15 and the working water tank 12 may be selected according to the actual use requirement, which is not particularly limited in the present invention.

In some embodiments of the invention, the bottommost end of the mounting interface 1211 may be no lower than the bottommost end of the steam outlet. For example, when the mounting interface 1211 is the same size as the opening of the steam outlet, the height of the central axis of the mounting interface 1211 is not lower than the height of the central axis of the steam outlet. When the opening size of the mounting interface 1211 is larger than the steam outlet, the bottommost end of the mounting interface 1211 is not lower than the bottommost end of the steam outlet. Thus, with the above arrangement, the liquid level in the water containing space can be prevented from being too high to be discharged through the installation interface 1211, and the normal operation of the steam valve 15 can be ensured.

According to some embodiments of the present invention, the opening degree of the steam valve 15 may be adjustable, and the opening degree of the steam valve 15 may be adjusted according to the pressure difference between the water containing space and the water replenishment tank 11 when the steam valve 15 is configured to be in an open state. For example, the opening degree of the steam valve 15 may be linearly changed according to the pressure difference between the water containing space and the water replenishment tank 11, and the opening degree of the steam valve 15 is gradually increased according to the pressure difference between the water containing space and the water replenishment tank 11. For another example, the opening degree of the steam valve 15 may include a first level, a second level, and a third level, the opening degree of which gradually increases. When the pressure difference between the water containing space and the water replenishing tank 11 is smaller than the first set pressure value, the opening of the steam valve 15 may be adjusted to the first level. When the pressure difference between the water containing space and the inside of the water replenishment tank 11 is between the first set pressure value and the second set pressure value (the second set pressure value is larger than the first set pressure value), the opening degree of the steam valve 15 can be adjusted to the second level. When the pressure difference between the water containing space and the water replenishing tank 11 is greater than the second set pressure value, the opening of the steam valve 15 may be adjusted to the third level. Thus, by the above arrangement, the pressure adjustment efficiency of the steam valve 15 to the inside of the working water tank 12 can be improved.

As shown in fig. 2 and 4, according to some embodiments of the present invention, the water inlet pipe assembly 13 may include a pipe body 131 and a check valve 132, a first end of the pipe body 131 may be connected to the water outlet, a check valve 132 may be provided between a second end of the pipe body 131 and the water inlet, and the check valve 132 may be unidirectionally conducted in a flow direction from the water replenishment tank 11 to the working tank 12, thereby ensuring normal operation of the working tank 12.

It will be appreciated that when the pressure in the water replenishment tank 11 is less than the pressure in the working tank 12, the water inlet pipe assembly 13 forms a siphon effect between the water replenishment tank 11 and the working tank 12 under the action of the pressure difference, and water in the working tank 12 can flow back into the water replenishment tank 11 through the water inlet pipe assembly 13, thereby causing dry heating of the heating device 14, not only affecting the normal operation of the working tank 12, but also having a greater potential safety hazard. By providing the check valve 132, the check valve 132 can be turned on unidirectionally in the flow direction from the water replenishment tank 11 to the working tank 12, thereby effectively preventing water in the working tank 12 from flowing back into the water replenishment tank 11, and ensuring normal operation of the tank assembly 1.

As shown in fig. 7, according to some embodiments of the present invention, there may be a plurality of working water tanks 12, and each working water tank 12 may be provided with a corresponding heating device 14 and a steam valve 15, and when the water tank assembly 1 is operated, the operation states of the heating devices 14 in each working water tank 12 may be controlled separately, thereby controlling one of the working water tanks 12 to operate to generate water vapor, controlling at least two of the working water tanks 12 to operate simultaneously, and controlling all of the working water tanks 12 to operate simultaneously. Thus, through the above arrangement, the use flexibility of the water tank assembly 1 can be improved, and thus the air humidity adjusting efficiency of the air processing apparatus 100 can be improved.

For example, when the humidity difference between the indoor air humidity and the proper air humidity is small, one of the working water tanks 12 is controlled to operate to generate water vapor. When the humidity difference between the indoor air humidity and the proper air humidity is large, at least two working water tanks 12 or all working water tanks 12 can be controlled to work simultaneously, so that a large amount of water vapor can be generated in unit time, and the aim of quickly adjusting the air humidity can be fulfilled.

As shown in fig. 7, in some embodiments of the present invention, the number of the water-replenishing water tanks 11 may be one, and the water-replenishing water tanks 11 may be provided with water outlets corresponding to the plurality of the working water tanks 12 one by one, so that by the arrangement, the water-replenishing water tanks 11 may realize a water-supplying effect of "one-to-many", and the water-replenishing water tanks 11 may simultaneously replenish water for the plurality of the working water tanks 12, so that not only the overall structure of the water tank assembly 1 may be simpler, but also the overall structure of the water tank assembly 1 may be more compact.

As shown in fig. 5, the working water tank 12 may be provided with a drain outlet communicating with the water containing space, and the water tank assembly 1 may further include a drain valve 16 for opening or closing the drain outlet, according to some embodiments of the present invention. Specifically, when the working water tank 12 is operated, the drain valve 16 is in a state of closing the drain outlet, whereby the water containing space can be normally stored. When the water in the working water tank 12 is required to be discharged after the working water tank 12 is stopped, the drain valve 16 may be controlled to open a drain outlet through which the water in the working water tank 12 may be discharged. Thus, by the above arrangement, the water in the working water tank 12 can be conveniently discharged, and the specific use requirements of the user can be satisfied. Alternatively, a drain outlet may be provided at the bottom of the working water tank 12, whereby the water in the water containing space can be easily discharged cleanly.

As shown in fig. 6, according to some embodiments of the present invention, the water tank assembly 1 may further include a temperature controller 17 for detecting the temperature in the working water tank 12, the temperature controller 17 may be provided on the working water tank 12, and when the temperature in the working water tank 12 exceeds a set temperature, the temperature controller 17 may control the heating device 14 to stop heating, thereby preventing the heating device 14 from being dry-burned to cause fire, and thus improving the use safety of the water tank assembly 1.

As shown in fig. 6, in some embodiments of the present invention, the water tank assembly 1 may further include a fixing bracket 18, the fixing bracket 18 may be provided on an outer circumferential wall of the working water tank 12 to fix the thermostat 17, the working water tank 12 may be provided with a steam delivery pipe 19 communicating with the steam outlet, and at least a portion of the fixing bracket 18 may be located below the steam delivery pipe 19 to support the steam delivery pipe 19, thereby not only facilitating fixing the thermostat 17, but also the fixing bracket 18 may also function to support the steam delivery pipe 19 without providing a supporting device to support the steam delivery pipe 19 exclusively, and the overall structure of the working water tank 12 may be made simpler and more compact.

For example, one end of the steam delivery pipe 19 may be connected to a steam outlet, and the water vapor in the working water tank 12 may be delivered into a specific area through the steam delivery pipe 19. The temperature controller 17 can be connected with the fixed bracket 18 in a welding connection mode, then the fixed bracket 18 can be connected with the box body 121 of the working water tank 12 in a screw connection mode, and the top of the fixed bracket 18 is stopped on the steam delivery pipe 19 to support the steam delivery pipe 19. Therefore, through the arrangement, the whole structure of the working water tank 12 can be more compact and distributed more reasonably, and the assembly space occupied by the water tank assembly 1 is greatly reduced.

The water tank assembly 1 of the present invention, which water tank assembly 1 can be used in the air treatment apparatus 100, will be described in detail in one specific embodiment with reference to the accompanying drawings. The air treatment device 100 may be an air conditioner, and the air treatment device 100 may be a humidifying device.

As shown in fig. 7, the water replenishing tank 11 is one, a water containing chamber may be disposed in the water replenishing tank 11, and a plurality of water outlets communicating with the water containing chamber may be disposed on the water replenishing tank 11. The working water tanks 12 are multiple, each working water tank 12 is internally provided with a water containing space, each working water tank 12 is provided with a water inlet and a steam outlet which are communicated with the water containing space, and the steam outlet can be positioned above the corresponding water inlet.

The water replenishing tank 11 is connected to a plurality of working tanks 12 through a plurality of water inlet pipe assemblies 13, respectively. Wherein, each water inlet pipe assembly 13 may include a pipe body 131 and a check valve 132, a first end of the pipe body 131 may be connected with a corresponding water outlet, a check valve 132 may be disposed between a second end of the pipe body 131 and a corresponding water inlet, and the check valve 132 may be unidirectional in a flow direction from the water replenishing tank 11 to the working tank 12.

As shown in fig. 1, the water replenishment tank 11 may include a body 111 and a tank cover 112, the body 111 may define a water containing chamber, a top of the water containing chamber is opened, and the tank cover 112 is provided on the body 111 to seal the water containing chamber. The body 111 is provided with a plurality of fixing lugs 111a which are distributed at intervals in the circumferential direction. The working water tank 12 comprises a hollow tank body 121, a water containing space can be defined in the tank body 121, and a plurality of fixing frames 122 which are distributed at intervals are arranged on the tank body 121. The tank assembly 1 is adapted to be hung on a support object (e.g., a ceiling) to which the plurality of fixing lugs 111a and the plurality of fixing frames 122 are simultaneously coupled when the tank assembly 1 is installed.

As shown in fig. 6, the heating device 14 is formed as two PTC heating pipes 14a provided in the water containing space, and the two PTC heating pipes 14a are located in the same horizontal plane. The two temperature controllers 17 are respectively arranged on the working water tank 12, the two temperature controllers 17 are in one-to-one correspondence with the two PTC heating pipes 14a, and when the temperature in the working water tank 12 exceeds the set temperature, each temperature controller 17 can respectively control the corresponding PTC heating pipe 14a to stop heating. The water tank assembly 1 further includes a fixing bracket 18, the fixing bracket 18 may be provided on an outer circumferential wall of the working water tank 12 to fix the temperature controller 17, a steam delivery pipe 19 communicating with the steam outlet may be provided on the working water tank 12, and at least a portion of the fixing bracket 18 may be located below the steam delivery pipe 19 to support the steam delivery pipe 19.

The water tank assembly 1 further includes a detection device which may be communicatively connected to the PTC heating tube 14a and the steam valve 15, respectively, and which may detect an operation current of the PTC heating tube 14a, and which may be configured to control the opening or closing of the steam valve 15 according to the operation current of the PTC heating tube 14 a. When the PTC heating tube 14a is submerged in the water containing space, the operating current of the PTC heating tube 14a is maintained. When a portion of the PTC heating tube 14a is located above the liquid surface, the operating current of the PTC heating tube 14a may decrease as the liquid level in the water containing space decreases.

Specifically, when the water tank assembly 1 is in operation, water may be contained within the water containing chamber of the refill water tank 11. The water replenishing tank 11 may be connected to a water source (e.g., a faucet), and water may be supplied to the water containing chamber through the water source. The water in the water holding chamber can enter the water inlet pipe assembly 13 through the water outlet and then enter the water replenishing tank 11 through the water inlet, so that water can be added to the water replenishing tank 11. When the water in the water replenishing water tank 11 enters the working water tank 12, the PTC heating pipe 14a can heat the water in the water containing space, and the water is heated and gasified to form water vapor, and the water vapor in the water containing space can be discharged through the vapor outlet. The water vapor discharged from the vapor outlet can enter the indoor space, thereby achieving the purpose of adjusting the humidity of the indoor air.

When the detection device detects that the working current of the PTC heating tube 14a is smaller than the set value, it indicates that the liquid level in the water containing space is reduced to the position where the water replenishing tank 11 is required to replenish water. After a first set time interval, the water vapor in the water containing space is condensed and converted into condensed water, and the air pressure in the water containing space is reduced. At this time, the detecting device can control the steam valve 15 to be opened, and external air can enter the working water tank 12 through the steam valve 15 to balance the pressure difference between the working water tank 12 and the water replenishing water tank 11, thereby preventing the siphon effect between the water replenishing water tank 11 and the working water tank 12 and ensuring that the water tank assembly 1 can normally operate.

With long-term use of the water tank assembly 1, condensed water is extremely easy to produce in the steam delivery pipe 19, the condensed water is accumulated to form a liquid seal 19a, and the liquid seal 19a can block the water vapor in the working water tank 12 from being discharged. Thereby, the amount of water vapor in the working water tank 12 is gradually increased, so that the pressure in the working water tank 12 is made greater than the pressure in the water replenishment water tank 11. Under the effect of pressure, the water in the water replenishing water tank 11 can not enter the water replenishing water tank 11 through the water inlet pipe assembly 13, so that the phenomenon of dry heating of the heating device 14 can occur, the service life of the heating device 14 can be shortened, and relatively large potential safety hazards exist. At this time, the steam valve 15 can be adjusted to an open state, and the steam in the working water tank 12 can be discharged through the steam valve 15, so that the pressure difference between the water replenishing water tank 11 and the working water tank 12 can be reduced, and the water in the water replenishing water tank 11 can smoothly enter the working water tank 12, so that the water tank assembly 1 can normally operate.

As shown in fig. 7, the air treatment apparatus 100 according to the embodiment of the present invention may include the water tank assembly 1 of the air treatment apparatus 100 according to the above-described embodiment of the present invention.

According to the air treatment device 100 provided by the embodiment of the invention, by arranging the water tank assembly 1, the operation of the air treatment device 100 can be more stable, and the air humidity adjusting effect of the air treatment device 100 on the indoor air can be improved.

As shown in fig. 7, according to some embodiments of the present invention, the air treatment apparatus 100 may further include a water receiving tray assembly 2, the water receiving tray assembly 2 may have a water receiving space 21a, and the water tank assembly 1 may be disposed above the water receiving space 21a, whereby water dropped from the water tank assembly 1 may enter into the water receiving space 21a, so that a water leakage phenomenon of the air treatment apparatus 100 may be prevented, and a use effect of the air treatment apparatus 100 may be improved.

In some embodiments of the present invention, the water-receiving tray assembly 2 may include a water-receiving tray 21 and a drain pipe assembly 22, a water-receiving space 21a may be defined in the water-receiving tray 21, and a drain outlet 21b communicating with the water-receiving space 21a may be provided on the water-receiving tray 21, so that the structural design of the water-receiving tray assembly 2 may be simpler, and the drain pipe assembly 22 may smoothly drain water in the water-receiving tray 21, so as to prevent the long-term water storage of the water-receiving tray 21 from affecting the service life of the water-receiving tray 21.

As shown in fig. 8-11, in some embodiments of the present invention, the drain pipe assembly 22 may include a siphon pipe 221 and a sleeve 222, the siphon pipe 221 may include a first pipe portion 221a and a second pipe portion 221b in communication, the second pipe portion 221b may be in communication with the drain port 21b, a water inlet end of the first pipe portion 221a may be located above a water outlet end of the second pipe portion 221b, an axial end of the sleeve 222 may be disposed open, the sleeve 222 may be sleeved on the first pipe portion 221a and be in clearance fit with the first pipe portion 221a to define a water inlet flow path 22a, the water inlet flow path 22a may be in communication with the water receiving space 21a and the water inlet end of the first pipe portion 221a, respectively, and the water inlet end of the water inlet flow path 22a may be located above the water outlet end of the second pipe portion 221 b.

Specifically, the drain pipe assembly 22 may introduce water in the water receiving space 21a to the drain port 21b for drainage purposes. Wherein the water receiving space 21a, the water inflow passage 22a, the first pipe portion 221a and the second pipe portion 221b communicate with each other. When the liquid level in the water receiving space 21a does not reach the set height, the water receiving tray 21 is in a water storage state. According to the principle of the communicating vessel, the liquid level in the water receiving space 21a and the liquid level in the water inlet flow path 22a are synchronously changed. When the liquid level in the water receiving space 21a is higher than the water inlet end of the first pipe portion 221a, water in the water inlet flow path 22a starts to enter the first pipe portion 221a, and water can be discharged through the first pipe portion 221a, the second pipe portion 221b, and the water outlet 21b in this order. According to the siphon principle, the water entering the siphon tube 221 can discharge the air in the siphon tube 221, and thus a negative pressure can be formed in the siphon tube 221. Thus, the water in the water receiving space 21a can be discharged through the water inlet passage 22a, the siphon pipe 221, and the water outlet 21b in this order. When the liquid level in the water receiving space 21a is lower than the water inlet end of the water inlet flow path 22a, the water discharge pipe assembly 22 stops discharging water. Through the arrangement, the structural design of the drain pipe assembly 22 can be simpler, and the drain effect of the drain pipe assembly 22 can be improved.

In a specific example of the present invention, both the sleeve 222 and the first pipe portion 221a may be formed in a cylindrical shape, and an inner diameter of the sleeve 222 is larger than an outer diameter of the first pipe portion 221 a. Wherein, the sleeve 222 includes an open end 222b and a sealed end 222a, the sleeve 222 can be sleeved on the first pipe portion 221a through the open end 222b, and the sealed end 222a is located above the first pipe portion 221a and is spaced from the water inlet end of the first pipe portion 221 a. Thus, when the water introduced into the first pipe portion 221a discharges the air in the siphon pipe 221, a stable negative pressure can be formed in the siphon pipe 221, and the drainage effect of the drain pipe assembly 22 can be improved.

The water tray assembly 2 of the present invention will be described in detail in one embodiment with reference to the accompanying drawings, the water tray assembly 2 comprising: a water receiving tray 21, a drain pipe assembly 22, a water leakage detection device 23 and a water baffle 24.

Wherein the water receiving tray 21 may include a bottom plate 211 and a shroud 212, the shroud 212 extending in a circumferential direction of the bottom plate 211 and being formed in a closed ring shape, the shroud 212 extending upward with respect to the bottom plate 211. The water baffle 24 is arranged in the water receiving disc 21, the water baffle 24 and the bottom plate 211 are formed into an integral part, two ends of the water baffle 24 in the length direction are respectively matched with the coaming 212 in a sealing way, therefore, the bottom plate 211, the coaming 212 and the water baffle 24 can be formed into a closed water receiving space 21a, and a water outlet 21b communicated with the water receiving space 21a can be formed in the water receiving disc 21.

As shown in fig. 11, the drain pipe assembly 22 may include a siphon pipe 221 and a sleeve 222, the siphon pipe 221 may include a first pipe portion 221a and a second pipe portion 221b communicating with each other, the first pipe portion 221a extending in a vertical direction, the second pipe portion 221b extending in a horizontal direction, and the second pipe portion 221b may communicate with the drain port 21 b. The water inlet end of the first pipe portion 221a may be located above the water outlet end of the second pipe portion 221b, one axial end of the sleeve 222 may be disposed in an open manner, the sleeve 222 may be sleeved on the first pipe portion 221a and is in clearance fit with the first pipe portion 221a to define a water inlet flow path 22a, the water inlet flow path 22a is respectively communicated with the water receiving space 21a and the water inlet end of the first pipe portion 221a, and the water inlet end of the water inlet flow path 22a may be located above the water outlet end of the second pipe portion 221 b. As shown in fig. 10 to 11, a water collecting portion 2111 recessed downward may be provided on the bottom wall of the water receiving tray 21, and the water inlet end of the water inlet flow path 22a may be located in the water collecting portion 2111.

As shown in fig. 9, the sleeve 222 and the first pipe portion 221a may each be formed in a cylindrical shape, and an inner diameter of the sleeve 222 is larger than an outer diameter of the first pipe portion 221a. Wherein, the sleeve 222 includes an open end 222b and a sealed end 222a, the sleeve 222 can be sleeved on the first pipe portion 221a through the open end 222b, and the sealed end 222a is located above the first pipe portion 221a and is spaced from the water inlet end of the first pipe portion 221a. Thus, when the water introduced into the first pipe portion 221a discharges the air in the siphon pipe 221, a stable negative pressure can be formed in the siphon pipe 221, and the drainage effect of the drain pipe assembly 22 can be improved. The top end of the sleeve 222 is provided with a connecting portion 2221, one end of the connecting portion 2221 is connected with the sleeve 222, the other end of the connecting portion 2221 extends towards the direction close to the water baffle 24, and the connecting portion 2221 is provided with a mounting hole 2221a. The water baffle 24 is provided with a screw column 241, and the mounting hole 2221a is opposite to the screw hole on the screw column 241. A set screw may be threaded through the mounting hole 2221a to the threaded column, thereby securing the sleeve 222 to the water deflector 24.

The water leakage detecting device 23 may include: the device comprises a control main board, a floater, a trigger switch, a first liquid level detection sensor, a second liquid level detection sensor and an alarm device, wherein the trigger switch, the first liquid level detection sensor, the second liquid level detection sensor and the alarm device are respectively in communication connection with the control main board. The trigger switch is disposed below the water inlet end of the first pipe 221a, and is a magnetic material. The guide cylinder is disposed adjacent to the trigger switch and is in communication with the water receiving space 21a, whereby the guide cylinder can be made to coincide with the liquid level in the water receiving space 21 a. The guide cylinder extends in the vertical direction, the float is formed as a spherical magnetic material piece and is provided in the guide cylinder. The second liquid level detection sensor is disposed flush with the water inlet end of the first pipe portion 221a to detect whether the liquid level reaches the water inlet end of the first pipe portion 221 a.

Specifically, when a water droplet in the tank assembly 1 falls into the water receiving tray 21, the float may float on the water surface. When the liquid level in the water receiving space 21a rises to a certain height, the float is magnetically matched with the trigger switch, the trigger switch is triggered, and the first liquid level detection sensor starts to work. The first liquid level detection sensor starts to detect the real-time liquid level in the water receiving space 21a and sends detection data to the control main board, and the control main board can judge the liquid level change in the water receiving space 21a at two adjacent moments. If the second liquid level detection sensor does not detect that the liquid level reaches the water inlet end of the first pipe portion 221a and the control main board detects that the liquid level in the water receiving space 21a is reduced, the control main board controls the alarm device to send an alarm signal to prompt a user to overhaul the water receiving tray 21. If the second liquid level detection sensor detects that the liquid level reaches the water inlet end of the first pipe portion 221a, the water leakage detection device 23 stops working, and the drain pipe assembly 22 starts draining.

It can be understood that since the water receiving space 21a, the water inflow path 22a, the first pipe portion 221a and the second pipe portion 221b communicate with each other. When the liquid level in the water receiving space 21a does not reach the set height, the water receiving tray 21 is in a water storage state. According to the principle of the communicating vessel, the liquid level in the water receiving space 21a and the liquid level in the water inlet flow path 22a are synchronously changed. When the liquid level in the drip tray 21 is higher than the water inlet end of the first pipe portion 221a, water in the water inlet flow path 22a starts to enter the siphon tube 221. According to the siphon principle, the water entering the siphon tube 221 can discharge the air in the siphon tube 221, and thus a negative pressure can be formed in the siphon tube 221. Thus, the water in the water receiving space 21a can be discharged through the water inlet flow path 22a, the siphon pipe 221, and the water discharge port 21 b. When the liquid level in the water receiving space 21a is lower than the water inlet end of the water inlet flow path 22a, the water discharge pipe assembly 22 stops discharging water. Since the water inlet end of the water inlet flow path 22a is located in the water collecting portion 2111, the drain pipe assembly 22 can drain the water in the water receiving tray 21.

As shown in fig. 12, according to the control method of the air treatment apparatus 100 of the above embodiment of the present invention, the heating device 14 may be a PTC heating tube 14a, and the control method may include:

The working current of the PTC heating tube 14a may be detected, and when the working current of the PTC heating tube 14a is less than the set current for the first set time, the steam valve 15 may be controlled to be adjusted to the open state, and the PTC heating tube 14a may be controlled to stop heating.

For example, the water tank assembly 1 of the air treatment device 100 may comprise detection means, which may be communicatively connected to the PTC heating tube 14a and the steam valve 15, respectively, and which may detect the operating current of the PTC heating tube 14 a. When the PTC heating tube 14a is submerged in the water containing space, the operating current of the PTC heating tube 14a is maintained. When a portion of the PTC heating tube 14a is located above the liquid surface, the operating current of the PTC heating tube 14a may decrease as the liquid level in the water containing space decreases. When the detection device detects that the working current of the PTC heating tube 14a is smaller than the set current, it indicates that the liquid level in the water containing space is lowered to the position where the water replenishing tank 11 is required to replenish water. After a first set time interval, the water vapor in the water containing space is condensed and converted into condensed water, and the air pressure in the water containing space is reduced. At this time, the detecting device can control the steam valve 15 to be opened, external air can enter the working water tank 12 through the steam valve 15 to balance the pressure difference between the working water tank 12 and the water replenishing water tank 11, and the water replenishing water tank 11 can normally replenish water for the working water tank 12. When the water level in the working water tank 12 reaches a level below the steam outlet, the water replenishment water tank 11 may stop replenishing water towards the working water tank 12 and the heating device 14 starts to operate to generate water steam.

Thus, by the arrangement, the liquid level in the water containing space can be judged according to the working current in the PTC heating pipe 14a, the siphon effect between the water replenishing water tank 11 and the working water tank 12 can be prevented, and the water entering the working water tank 12 is prevented from being directly discharged through the steam outlet, so that the water tank assembly 1 can be ensured to normally run.

According to the control method of the air treatment apparatus 100 of the embodiment of the present invention, the opening and closing of the steam valve 15 can be controlled to adjust the pressure in the working water tank 12 by detecting the working current of the PTC heating pipe 14a, so that the operation is convenient, and thus the water replenishment water tank 11 can be ensured to be able to normally replenish water to the working water tank 12, and thus the water tank assembly 1 can be ensured to be able to normally operate.

According to some embodiments of the present invention, a first pressure detecting device for detecting the pressure in the working water tank 12 may be provided in the working water tank 12, a second pressure detecting device for detecting the pressure in the water tank 11 may be provided in the water tank 11, the working water tank 12 may further include a detecting device, the detecting device may determine a difference between the pressure values detected by the first pressure detecting device and the second pressure detecting device, and when the difference is greater than a set value, the detecting device may control the steam valve 15 to be opened, thereby enabling the water tank 11 to smoothly replenish the working water tank 12.

Specifically, when the difference between the pressure values detected by the first pressure detecting means and the second pressure detecting means is larger than the set value, it is indicated that the pressure in the working water tank 12 is too high to affect the normal water replenishment of the working water tank 12 by the water replenishment water tank 11. At this time, by controlling the steam valve 15 to open, the steam in the working water tank 12 is discharged through the steam valve 15, the pressure in the working water tank 12 is reduced, and the water in the water replenishment water tank 11 can smoothly flow into the working water tank 12.

It will be understood that, of course, the first pressure detecting device may be provided only in the working water tank 12, so that the pressure in the water replenishing tank 11 may be controlled to be the same as the external atmospheric pressure, and the detecting device may determine the difference between the pressure value detected by the first pressure detecting device and the external atmospheric pressure to control the opening and closing of the steam valve, thereby ensuring that the water replenishing tank 11 can perform normal water replenishing on the working water tank 12.

According to some embodiments of the invention, the control method may further include: after the steam valve 15 is adjusted to the open state for a second set time, the steam valve 15 may be controlled to be closed and the PTC heating pipe 14a may be controlled to perform heating. Specifically, when the steam valve 15 is adjusted to an open state, external air can be introduced into the working water tank 12, whereby the pressure difference between the water replenishment water tank 11 and the working water tank 12 can be balanced, and the water replenishment water tank 11 can normally replenish water to the working water tank 12. After a second set time interval, the liquid level in the water replenishing tank 11 reaches the set liquid level, at this time, the steam valve 15 can be controlled to be closed, and the PTC heating pipe 14a is heated. Thus, by the above arrangement, the automatic control of the water tank assembly 1 can be realized, and the degree of automation of the air treatment apparatus 100 can be improved.
