The magnetic induction intensity of the magnetic element 221 provided on the float 22 detected by the magnetic induction sensor 231 above the guide rail 21 changes. During the rise of the water level, the float 22 rises with the water level, and the magnetic induction intensity signal detected by the magnetic induction sensor 231 increases accordingly; when the magnetic induction intensity reaches the set value, the drain valve 30 opens the water outlet according to the magnetic induction intensity signal to realize the water collecting tank of drainage. In this embodiment, the current water level is determined by the change of the magnetic induction intensity signal obtained by the float device 20, so that the water collecting tank of the dehumidifier can realize the accurate automatic drainage function, with high reliability, and can avoid the overflow of water in the tank.

Here, the magnetic induction intensity is used to express the strength of the magnetic field formed by the magnetic member 221 .

The magnetic induction sensor 231 is used to convert the detected magnetic induction intensity into an electrical signal. When the magnetic induction intensity is high, it means that the magnetic field intensity is high, and the contacts in the magnetic induction sensor 231 are pulled and turned on, and an electrical signal is sent; when the magnetic induction intensity is low, it means that the magnetic field intensity is weakened, and the contacts in the magnetic induction sensor 231 are disconnected and stopped.

In the embodiment of the present disclosure, when the water level is low, the position of the float 22 is also low, and the magnetic member 221 disposed thereon is far away from the magnetic induction sensor 231 disposed above the float guide rail 21. At this time, the magnetic induction sensor 231 detects The magnetic induction intensity is weak, and the contacts in the magnetic induction sensor 231 cannot be pulled together, so no electrical signal is sent. As the water level rises, the distance between the magnetic member 221 on the float 22 and the magnetic induction sensor 231 gradually decreases, and the magnetic induction intensity detected by the magnetic induction sensor 231 gradually increases; when the float 22 rises to the drainage water level, the magnetic induction intensity also increases accordingly. When the drainage threshold is reached, the contacts in the magnetic induction sensor 231 are pulled in and an electrical signal is sent, then the drainage valve 30 on the drainage port side at the bottom of the box 10 is opened, and the waste water in the box is discharged from the drainage valve 30 . After the waste water is discharged, the water level where the float 22 is located gradually decreases, the distance between the magnetic element 221 and the magnetic induction sensor 231 gradually increases, and the magnetic induction intensity detected by the magnetic induction sensor 231 gradually weakens; when the water level drops to a safe water level, the magnetic induction intensity also increases with When it falls to the safety threshold, the contacts in the magnetic induction sensor 231 are disconnected, the electrical signal is stopped, the drain valve 30 is closed, and drainage is stopped.

Optionally, the dehumidifier water collection tank further includes:

The controller 40 is respectively connected to the drain valve 30 and the magnetic induction sensor 231 ; the controller 40 controls the opening or closing of the drain valve 30 according to the magnetic induction intensity signal of the magnetic induction sensor 231 .

The magnetic induction sensor 231 converts the magnetic induction intensity signal into an electrical signal and sends it to the controller 40. The controller 40 is connected to the drain valve 30, and controls the opening or closing of the drain valve 30 according to the electrical signal information, thereby realizing the automatic opening of the drain valve 30, which is more intelligent , with higher accuracy.

Optionally, the dehumidifier water collection tank further includes:

The water pump 31 is arranged below the drain valve 30 and is connected to the controller 40 for starting the drainage according to the opening signal of the controller 40 . By setting the water pump 31 to speed up the drainage speed, the drainage efficiency is improved.

Here, the water pump 31 connected to the controller 40 is provided. When the controller 40 sends an opening signal according to the electrical signal output by the magnetic induction sensor 231, the drain valve 30 is opened, and the water pump 31 is started to pressurize and accelerate the discharge of waste water, so that the inside of the water collecting tank is accelerated. The water level drops rapidly to achieve rapid drainage effect.

Optionally, the float device 20 further includes: a float bracket, which is arranged on the top of the float guide rail 21, and the magnetic induction sensor 231 is arranged on the float bracket. By setting the float bracket, the protection and fixation of the magnetic induction sensor 231 is realized.

Optionally, the float bracket is also connected to the inner wall of one side of the box body 10 through the connecting assembly to realize the fixation of the float guide rail 21, so as to prevent the float guide rail 21 from shaking due to the fluctuation of the water level in the box body 10, so that the float 22 is connected to the magnetic induction sensor. The detection value error between 231 is large, and the misoperation of drainage occurs.

Here, the connection components can be a buckle set on one side of the float bracket and a slot set at a corresponding position on the inner wall of the box body 10; Limit groove on the top.

Optionally, the float 22 has a circular structure and is suitable for being sleeved on the float guide rail 21 . The smooth side wall of the float 22 can reduce the friction with the liquid, so as to avoid the influence of the resistance on the moving degree on the float guide rail 21, resulting in false detection of the water level.

Specifically, the float guide 21 includes a hollow tube body, and the annular float 22 is sleeved on the hollow tube body. The ratio of the inner diameter of the float 22 to the diameter of the hollow tube body is 1.05:1-1.2:1. In this way, it is avoided that the float 22 and the float guide rail 21 are attached too tightly, and the movement of the float 22 is affected due to excessive friction, resulting in false detection of the water level.

Optionally, a limiting portion 24 is provided at the bottom of the float guide rail 21 ; the limiting portion 24 has a circular structure and is suitable for being fixed to the bottom of the float guide rail 21 .

Here, the limiting portion 24 is used to limit the movement of the float 22 , and the limiting portion 24 to the bottom of the float guide rail 21 is a safe water level. By arranging the limiting portion 24, the movable path of the float 22 in the water collecting tank is shortened, the wear on the float 22 is reduced, and the service life of the device is prolonged. On the other hand, the annular structure is easy to install, and the friction with the liquid is small, which can reduce wear and tear.

In this way, by designing the float 22 with a circular structure, it is fixed to the bottom of the float guide rail 21 to form a limit for the movable float 22, so that when the water level in the water collecting tank drops to a lower position relative to the safe water level, the float 22 No need to follow and continue to descend, shorten the moving path and reduce wear and tear.

Optionally, the outer diameter of the limiting portion 24 is larger than the inner diameter of the float 22 . In this way, while realizing the limit of the descending path of the float 22, the occupation of the volume of the water collecting tank is reduced, and the installation of the float device 20 in the water collecting tank will lead to the reduction of the volume for accommodating waste water, the reduction of the water collection volume, and the occurrence of frequent drainage. Phenomenon.

Optionally, the height ratio of the limiting portion 24 to the float guide rail 21 is 1:5-1:3. In this way, by setting the height ratio between the limiting portion 24 and the float guide rail 21, the area division of the safe water level in the water collecting tank is realized, so that when the water level in the water collecting tank drops to a lower position relative to the safe water level, the float 22 does not need to be Follow and continue to descend, shorten the moving path and reduce wear and tear.

In actual use, the magnetic induction sensor 231 is used as a Hall sensor. The Hall sensor is a magnetic field sensor that works according to the Hall effect, which can sense the magnetic field intensity (magnetic induction intensity) and output a corresponding voltage value.

Optionally, a switch-type Hall sensor is used in this embodiment, so as to output a magnetic induction intensity signal to the controller 40 to realize opening or closing of the drain valve 30 .

Specifically, the working magnetic induction intensity value and the releasing magnetic induction intensity value are set for the Hall sensor. When the applied magnetic induction intensity is greater than or equal to the working magnetic induction intensity value, the Hall sensor outputs a low level to the controller 40, and the controller 40 outputs an instruction to open the drain valve 30, or the drain valve 30 and the water pump 31, to start draining; When the magnetic induction intensity drops below the working magnetic induction intensity value, the output level of the Hall sensor remains unchanged. When the applied magnetic induction intensity drops below the release magnetic induction intensity value, the Hall sensor outputs a high level to the controller 40, and the output of the controller 40 is turned off Instruct the drain valve 30, or the drain valve 30 and the water pump 31, to stop the drain operation.

Wherein, the numerical value of the working magnetic induction intensity value is greater than the numerical value of the releasing magnetic induction intensity value.

Further, when the Hall sensor detects that the strength of the magnetic field where the float 22 is located is greater than or equal to the working magnetic induction intensity value, the distance between it and the float 22 is the first distance; when the Hall sensor detects that the strength of the magnetic field where the float 22 is located is less than When the magnetic induction intensity value is released, the distance between it and the float 22 is the second distance; wherein, the first distance is smaller than the second distance.
