Alternatively, in the example of fig. 3, the water tank 3 has a substantially rectangular parallelepiped shape, and may be provided in other shapes according to the actual design requirements of the humidifying device 100.

Specifically, before the humidifying device 100 starts working, the water inlet pump 32 is started first, water flows into the water storage cavity 311 through the water inlet pipe 312, after the water amount in the water storage cavity 311 reaches a set capacity, the water inlet pump 32 is closed to stop water inlet into the water storage cavity 311, then the humidifying device 100 starts working, and the water in the water storage cavity 311 can be taken away through the fan assembly 2 to adjust the indoor humidity. After the humidification is completed, the water outlet pump 33 is turned on, and the remaining water in the water storage cavity 311 is discharged out of the water tank body 31 through the water outlet pipe 313. Therefore, on one hand, the water inlet pump 32 and the water outlet pump 33 are arranged, so that water can be conveniently injected into the water storage cavity 311 or discharged from the water storage cavity 311, and the humidifying work of the humidifying device 100 is more smoothly carried out; on the other hand, when the humidifying device 100 does not work, the accumulation of water in the water storage cavity 311 can be avoided, the rusting caused by the long-time contact of the fan assembly 2 and the water after the humidifying device 100 is closed can be avoided, the service time of the humidifying device 100 is prolonged, and the corners and the gaps on the bottom wall of the water storage cavity 311 are reduced because the bottom wall of the water storage cavity 311 is arc-shaped, so that the probability of growing bacteria in the water storage cavity 311 can be greatly reduced, the cleanliness of the water storage cavity 311 is improved, and the safety of a user using the air conditioner is further improved.

Further, the humidifying device 100 further comprises a control device (not shown) for controlling the on/off of the water inlet pump 32 and the water outlet pump 33. When the humidifying device 100 is started, the control device controls the water inlet pump 32 to be started, and controls the water outlet pump 33 to be closed; when the humidifying device 100 is turned off, the control device controls the water inlet pump 32 to be turned off, and the control device controls the water outlet pump 33 to be turned on. From this, set up controlling means, can realize the operation automation of filling water and drainage in basin body 31, easily control the water yield in basin body 31, improve the convenience of basin 3 water injection or drainage, and then improve humidification device 100's work efficiency.

According to some embodiments of the present invention, referring to fig. 4 and 5, a float switch 34 is provided in the water tank 3, the float switch 34 is electrically connected to the control device, and the float switch 34 and the control device work together to control the height of the water level in the water tank 3.

When the humidifying device 100 starts to work, firstly, the control device controls the water inlet pump 32 to be started, water flows into the water storage cavity 311 through the water inlet pipe 312, when the water level line (as indicated by an arrow a in fig. 4 and 5) is higher than the float switch 34, the float switch 34 receives water level information and sends a signal to the control device, the control device controls the water inlet pump 32 to be stopped, water in the water storage cavity 311 is prevented from overflowing, and meanwhile, the water outlet pump 33 is in a closed state. Then, after pausing for a few seconds and waiting for the water level line in the water storage cavity 311 to be stable, the float switch 34 detects whether the water level line in the water storage cavity 311 is in place again, if the water level line is lower than a set value, the control device controls the water inlet pump 32 to be started to continue to inject water into the water storage cavity 311, and if the water level line reaches the set value, the fan assembly 2 is started after pausing for a few seconds. The fan assembly 2 rotates to make the fan assembly 2 adhere to the water in the water storage cavity 311, so that the air flowing into the humidifying device 100 from the indoor unit is humidified and then discharged to the indoor. In the working process of the humidifying device 100, the float switch 34 detects a water level line at intervals, and after the water level line is lower than a set value, the float switch 34 transmits a signal to the control device, and the control device controls the water inlet pump 32 to start injecting water into the water storage cavity 311. After the humidifying device 100 is finished, the control device controls the water outlet pump 33 to be turned on, the water in the water storage cavity 311 is discharged out of the humidifying device 100 through the water outlet pipe 313, and meanwhile, the water inlet pump 32 is in a turned-off state. It should be noted that the time for turning on the water outlet pump 33 during the water discharge may be longer than the time required for filling the water storage cavity 311 with water, so as to ensure that the water in the water storage cavity 311 is completely discharged.

Through the cooperation of the control device and the float switch 34, when the water amount in the water storage cavity 311 is reduced, water can be supplemented into the water storage cavity 311 in time, the humidifying device 100 is prevented from working in the water storage cavity 311 in a water shortage state, so that the normal operation of the humidifying work of the air conditioner is ensured, the height of the water level line in the water storage cavity 311 can be accurately controlled, and the accuracy of water level adjustment in the water storage cavity 311 is effectively ensured.

According to some embodiments of the present invention, referring to fig. 3 and 4, the water inlet pump 32 and the float switch 34 are respectively located at both ends of the sink body 31. Therefore, the interference of the working time of the water inlet pump 32 on the detection of the water level information of the float switch 34 can be reduced, the accuracy of the water level signal in the water storage cavity 311 is effectively ensured, and the float switch 34 can accurately judge the height of the water level in the water storage cavity 311. The water outlet pump 33 is located on one side of the water tank body 31 far away from the fan assembly 2, for example, the water outlet pipe 313 can be arranged in the middle of the bottom of the water tank body 31, the water outlet pump 33 is also located in the middle of the bottom of the water tank body 31 at the moment, the middle of the bottom of the water tank body 31 is the lowest point due to the fact that the bottom wall of the water storage cavity 311 is arc-shaped, and therefore water can be conveniently discharged from the water storage cavity 311, and water accumulation in the water storage cavity 311 is avoided.

For example, in the example of fig. 3 and 4, an object 35 is disposed on a side of the sink body 31 away from the water inlet pump 32, the object 35 is fixedly connected to the sink body 31, an object chamber 351 is formed on the object 35, the object chamber 351 is communicated with the water storage chamber 311, and the float switch 34 is disposed in the object chamber 351. So set up, can be so that float switch 34 arranges the outside in water storage chamber 311 in, and put thing 35 and can play the guard action to float switch 34, interfere with float switch 34 when avoiding fan subassembly 2 to rotate, also can accurately detect the water level height in water storage chamber 311 simultaneously.

Optionally, the humidifying device 100 further includes a water tank (not shown) which is communicated with the water storage chamber 311 through a water inlet pipe 312. Therefore, water in the water tank can be injected into the water storage cavity 311 through the water inlet pipe 312 in time, the supply of the water amount in the water tank 3 is guaranteed, and the humidification work is guaranteed to be smoothly carried out. It is understood that the water storage cavity 311 may be connected to another water source through the water inlet pipe 312 for supplying water to the water tank 3.

According to some embodiments of the present invention, referring to fig. 1 and 2, the humidifying device 100 further includes a heating element 4, the heating element 4 is disposed in the housing 1 and located between the second air inlet 11 and the fan assembly 2. When the humidifying device 100 works, air in the humidifying device 100 flows to the fan assembly 2 after passing through the heating element 4, so as to take away moisture on the fan assembly 2 and blow the moisture to the room. If the heating member 4 is not provided on the humidifying device 100, when the humidifying device 100 is in operation, the temperature in the humidifying device 100 is reduced due to the increase of humidity and the volatilization of moisture in the air humidified by the humidifying device 100, and thus the temperature of the air humidified is reduced. Therefore, the heating element 4 is provided, on one hand, the air flowing in from the second air inlet 11 can be heated according to the difference between the set value and the actual temperature value of the temperature in the humidifying device 100, so as to maintain the temperature in the humidifying device 100 constant, and further avoid the temperature reduction of the air discharged to the room. On the other hand, with water storage chamber 311 water-logging back of discharging completely, through opening heating member 4 and starting fan subassembly 2, can dry basin 3 and fan subassembly 2, reduce the moisture in the basin 3 and on the fan subassembly 2, keep basin 3 and fan subassembly 2's drying, reduce breeding of the interior bacterium of water storage chamber 311, improve humidification device 100's cleanliness to reduce the probability that fan subassembly 2 damaged.

According to some specific embodiments of the present invention, referring to fig. 6, 7 and 8, the fan assembly 2 comprises a first fan 21, a drive member 22 and a second fan 23. The first fan 21 is disposed along the length direction (the direction indicated by the arrow B in fig. 1) of the housing 1, and the driving member 22 is electrically connected to the first fan 21, and the driving member 22 is used for driving the first fan 21 to rotate. The second fan 23 is sleeved on the outer peripheral side of the first fan 21, the second fan 23 and the first fan 21 are spaced from each other, and the air blown out by the first fan 21 drives the second fan 23 to rotate.

For example, the driving member 22 may be provided at one end in the longitudinal direction of the first fan 21. The central axis of the first fan 21 coincides with the central axis of the second fan 23 along the length direction of the casing 1 so that the air in the first fan 21 can uniformly flow into the second fan 23. When the humidifying device 100 works, the first fan 21 rotates along the axial direction of the first fan 21 under the action of the driving member 22, air flowing into the housing 1 through the second air inlet 11 can flow into the first fan 21 from one end of the first fan 21 in the length direction, and flows out to the second fan 23 from the circumferential direction of the first fan 21 under the centrifugal action, at this time, the air flowing to the second fan 23 can push the second fan 23 to rotate, the second fan 23 rotates to pass through the water storage cavity 311, and water in the water storage cavity 311 is attached to the outer circumferential surface of the second fan 23. When the air flows out of the second blower 23, the moisture on the second blower 23 is taken away, and the air flows into the room through the second air outlet 12, so that the indoor air is humidified. Therefore, through the matching of the first fan 21 and the second fan 23, only one driving member 22, such as a motor, can be arranged to simultaneously drive the first fan 21 and the second fan 23 to rotate, so that the number of the driving members 22 can be reduced, the production cost of the air conditioner can be reduced, and the energy consumption of the air conditioner can be reduced.

Specifically, referring to fig. 8, 9 and 10, the first fan 21 includes a first body 211 and a plurality of first blades 212, the plurality of first blades 212 being spaced apart from each other in a circumferential direction of the first body 211, and the plurality of first blades 212 being disposed obliquely. The second fan 23 includes a second body 231 and a plurality of second blades 232, the plurality of second blades 232 are spaced apart from each other along a circumferential direction of the second body 231, the plurality of second blades 232 are obliquely disposed, and at least a portion of the plurality of second blades 232 is located in the water storage cavity 311. In the description of the present invention, "a plurality" means two or more. The direction of the tilt of each first vane 212 is opposite to the direction of the tilt of each second vane 232.

For example, in the example of fig. 7 and 8, each of the first vanes 212 may be inclined to the right side in the radial direction of the first body 211 while the inclination direction of the plurality of first vanes 212 is clockwise, and each of the second vanes 232 may be inclined to the left side in the radial direction of the second body 231 while the inclination direction of the plurality of second vanes 232 is counterclockwise. With this arrangement, when the first fan 21 rotates in the clockwise direction, air flowing out from the middle of two adjacent first blades 212 (in the direction indicated by the arrow C in fig. 4 and 5) flows toward the second blade 232 by the centrifugal force of the first fan 21, and the air flowing onto the second blade 232 is divided into two parts. Wherein: a part of air can flow out of the second fan 23 (indicated by an arrow D in fig. 4 and 5) from between two adjacent second blades 232 carrying the water on the second blades 232, and the other part of air acts on the surface of the second blades 232 perpendicularly, so that a component force in the tangential direction of the circumference of the second body 231 is generated on the second blades 232, and the component force can push the second fan 23 to rotate clockwise, so that a layer of water film is formed on the second blades 232 passing through the water storage cavity 311, and with the rotation of the second fan 23, the second blades 232 can continuously supplement the water film from the water storage cavity 311, thereby effectively ensuring the humidifying effect of the humidifying device 100.

Wherein, the smaller the included angle between the second vane 232 and the tangent of the second body 231 in the circumferential direction is, the better. Therefore, the contact area between the second blade 232 and the water in the water tank 3 can be increased, which is beneficial to forming a water film on the second blade 232, and the humidifying efficiency of the humidifying device 100 can be improved.

Alternatively, referring to fig. 4, the water level in the water tank 3 may be set to just submerge the second blade 232 of the second fan 23. If the water level in the water tank 3 is too high, the resistance of the second fan 23 during rotation may be increased, and if the water level in the water tank 3 is too low, the surface of the second blade 232 is not likely to form a water film, and the humidification efficiency of the humidification apparatus 100 may be reduced. Therefore, the humidifying effect of the humidifying device 100 can be further improved by reasonably setting the water level height.

According to some embodiments of the present invention, each second blade 232 is a water-absorbing blade. From this, second blade 232 has better hydroscopicity, can be convenient for form the water film on second blade 232, and then effectively guarantee humidification device 100's humidification effect.

Optionally, an induced draft fan (not shown) may be disposed between the humidifying device 100 and the indoor unit, one end of the induced draft fan is communicated with the first air outlet, the other end of the induced draft fan is communicated with the second air inlet 11, the induced draft fan can guide air discharged from the indoor unit into the humidifying device 100, so as to avoid air leakage, improve the air intake of the humidifying device 100, and further improve the humidifying efficiency of the humidifying device 100.
