The embodiment of the present invention provides a dehumidifier, which will be described in detail with reference to fig. 1 to 10C.

In an embodiment of the present invention, as shown in fig. 1 and 4 to 6, the dehumidifier includes:

a water tank 200 having an installation opening 210 facing upward;

the body 100 has an idle state and a working state, in the idle state, the body 100 is at least partially accommodated in the water tank 200 through the mounting opening 210, and in the working state, the body 100 extends out relative to the water tank 200 through the mounting opening 210; and the number of the first and second groups,

the water level detecting assembly includes at least one floating trigger assembly 220 disposed in the water tank 200 and at least one water level switch 120 disposed on the body 100, wherein the floating trigger assembly 220 is used for triggering the water level switch 120.

Specifically, as shown in fig. 2 and 3, the body 100 includes a case, an axial flow fan 150, and a dehumidifying apparatus. In this embodiment, the dehumidifying apparatus includes an evaporator 130 and a condenser 140, an air inlet 111 is disposed on a side wall of the housing, an air outlet 112 is disposed on a top wall of the housing, and the axial flow fan 150, the evaporator 130 and the condenser 140 are disposed in the housing. During the operation of the dehumidifier, firstly, the axial flow fan 150 draws the humid air in the room into the housing through the air inlet 111, then the evaporator 130 condenses the water vapor in the air into water drops, the water vapor in the air is removed, the condenser 140 heats and dries the air after removing the water vapor, the air is recovered to normal temperature, and finally the dried air is blown out through the air outlet 112. Of course, in other embodiments, the dehumidification device may also adopt a dehumidification method such as an adsorption type.

A water pan 170 is further disposed in the casing, and the water pan 170 is located right below the evaporator 130 and the condenser 140 to separate the casing into a dehumidification air duct for heat exchange and a containing cavity for installing electric control components (such as an electric control box, a fan capacitor, and a compressor 160 capacitor). Therefore, the space is fully and reasonably utilized, the arrangement of components in the machine body 100 is more reasonable and compact, and the phenomenon that condensation generated by the evaporator 130 drips onto the electric control assembly to affect the electric control stability of the dehumidifier and the safety of a circuit can be avoided.

Referring also to fig. 4, the housing includes a bottom plate 180 under the water-receiving tray 170, and a receiving cavity is formed between the water-receiving tray 170 and the bottom plate 180. It can be understood that the chassis 180 is located at the bottom of the body 100, on one hand, the chassis can support and protect the body 100, and on the other hand, the chassis can also serve as a transfer station for the condensed water between the water pan 170 and the water tank 200, so that the condensed water collected by the water pan 170 can smoothly flow into the water tank 200 through the chassis 180. In this embodiment, the water level switch 120 is disposed on the side wall of the chassis 180, so as to shorten the distance between the floating trigger component 220 and the water level switch 120, so that the floating trigger component 220 can trigger the water level switch 120 in time in the process of rising along with the water level in the water tank 200, and the water level switch 120 can feed back the water level in the water tank 200 in time, so that the dehumidifier can control the working state of the body 100 as soon as possible.

In the technical scheme of the utility model, when the machine body 100 is in an idle state, at least part of the machine body 100 can be accommodated in the water tank 200 through the mounting opening 210 of the water tank 200, so that the gravity center of the dehumidifier can be reduced, the dehumidifier can be placed stably and is not prone to toppling over, the overall occupied space of the dehumidifier is reduced, and a user can place the dehumidifier conveniently; when the dehumidifier is in a working state, the dehumidifier body 100 extends out relative to the water tank 200, so that the air outlet 112 on the dehumidifier body 100 is at a higher position, the dehumidified air can be diffused into the whole indoor space more quickly, the volume of the water tank 200 can be greatly increased, the water tank 200 can store more water, and the continuous working time of the dehumidifier can be greatly prolonged. On the basis, a water level detection assembly is additionally arranged in the dehumidifier and comprises a floating trigger assembly 220 arranged in the water tank 200 and a water level switch 120 arranged on the machine body 100, the floating trigger assembly 220 can trigger the water level switch 120 along with the rise of the water level in the water tank 200, so that the water level detection assembly can detect the height of the water level in the water tank 200 in real time, the dehumidifier can conveniently control the working state of the dehumidifier according to the height of the water level, the water in the water tank 200 can be discharged or poured out in time when the water level in the water tank 200 is higher, the overflow of the water in the water tank 200 is further avoided, and the normal operation of the dehumidifier is ensured.

Further, as shown in fig. 7 and 10A to 10C, the floating trigger assembly 220 includes a float 221, a support rod 222 extending upward from the float 221, and at least one trigger 223 disposed on the support rod 222, wherein the float 221 rises with the rise of the water level in the water tank 200, so as to drive the trigger 223 of the corresponding floating trigger assembly 220 to trigger the water level switch 120. It can be understood that, in the water tank 200, the floating trigger assembly 220 is floated on the water surface by the buoyancy received by the float 221, and as the water level rises, the float 221 also naturally rises and drives the trigger 223 to rise, when the trigger 223 moves to the trigger position, the water level switch 120 is triggered, and then the water level switch 120 feeds back the corresponding water level detection result to the display device 190 or the controller of the body 100. The float 221 includes any one of a foam float, a plastic float, and a wooden float. In other embodiments, the float 221 may be a hollow float, or other material having a density less than water may be used. The present invention does not limit the material type and the specific structure of the float 221 as long as the float 221 can float on the water surface.

Specifically, the water level detecting assembly may be a contact type water level detecting assembly, for example, the water level switch 120 is a tact switch, and the trigger 223 is a trigger head, so that the trigger 223 needs to directly touch the water level switch 120 to trigger the water level switch 120. The water level detecting assembly may also be a non-contact water level detecting assembly, for example, the water level switch 120 is a hall switch, and the trigger 223 is a magnet; alternatively, the water level switch 120 is a laser sensor, and the trigger 223 is a light blocking member or a light reflecting member. The two triggers 223 can trigger the water level switch 120 without touching the water level switch 120 as long as the preset trigger position is reached.

Further, as shown in fig. 10A, the water level switch 120 is laterally provided in plural, and the floating trigger assembly 220 is correspondingly provided in plural, and the interval between the trigger 223 and the bottom of the float 221 is different among the plural different floating trigger assemblies 220. In this embodiment, there are two water level switches 120 horizontally, there are two floating trigger assemblies 220 correspondingly, when the water tank 200 is in the initial position, the distance between the plurality of trigger members 223 and the corresponding water level switches 120 is the same, but in the process of rising the water level, the trigger member 223 with a larger distance from the bottom of the float 221 will rise first due to the buoyancy of the water surface, so that the trigger member 223 will trigger the corresponding water level switch 120 first and detect the first water level; as the water level of the water tank 200 continues to rise, the trigger 223 spaced apart from the bottom of the float 221 by the buoyancy of the water surface rises, and thus the trigger 223 triggers the corresponding water level switch 120 and detects the second water level. It can be understood that the first water level can be set as the early warning water level, and the second water level is the warning water level, so that when the water level detection assembly detects that the water in the water tank 200 is close to the full water level, the dehumidifier can perform warning display or give an alarm sound to remind the user to discharge or pour out the water in the water tank 200 in time, and further avoid the water in the water tank 200 from overflowing to the ground due to overfilling.

In another embodiment, as shown in fig. 10B, the supporting rod 222 is provided with a triggering member 223, and the plurality of water level switches 120 are longitudinally provided, and the triggering member 223 triggers the plurality of water level switches 120 one by one in the process of rising with the water level in the water tank 200. It can be understood that, during the water level of the water tank 200 is rising, the trigger 223 will first trigger the water level switch 120 closest to its initial position and detect the first water level; as the water level of the water tank 200 continues to rise, the trigger 223 gradually rises and triggers the next water level switch 120, thereby sequentially detecting the second water level, the third water level, and the like. The technical scheme of the embodiment can detect a plurality of water levels of the water tank 200 in real time so that a user can know the water level condition in the water tank 200 in time.

In still another embodiment, as shown in fig. 10C, the water level switch 120 is provided with one, and the support bar 222 is provided with a plurality of triggering members 223 at intervals in the longitudinal direction, and the plurality of triggering members 223 trigger the water level switch 120 one by one as the water level in the water tank 200 rises. It can be understood that, in the process of raising the water level of the water tank 200, the trigger 223 having the initial position closest to the water level switch 120 will trigger the water level switch 120 first, and detect the first water level; as the water level of the water tank 200 continues to rise, the remaining trigger 223 gradually rises to trigger the water level switch 120, thereby sequentially detecting the second water level, the third water level, and the like. Similarly, the technical solution of this embodiment can also detect a plurality of water levels of the water tank 200 in real time, so that the user can know the water level condition in the water tank 200 in time.

In this embodiment, as shown in fig. 5 to 9, a mounting cover 230 is disposed on a side wall of the water tank 200, a water inlet 233 is disposed on the mounting cover 230, and the floating trigger assembly 220 is vertically and floatingly mounted in the mounting cover 230. Wherein, the water inlet 233 may be opened on the front sidewall or the bottom sidewall of the mounting cover 230. Optionally, the inlet 233 may be a circular hole or a square hole, to this the utility model discloses do not restrict. It can be understood that, in order to avoid the floating trigger assembly 220 from moving laterally on the water surface and affecting the triggering of the water level switch 120, the present embodiment limits the lateral movement of the floating trigger assembly 220 through the mounting cover 230, and simultaneously ensures that the floating trigger assembly 220 can float up and down to normally trigger the water level switch 120. In addition, the mounting cap 230 also protects the floating trigger assembly 220 from debris, preventing the floating trigger assembly 220 from falling out of the tank 200 and being damaged when the tank 200 is being poured.

Further, as shown in fig. 7, the inner side wall of the mounting cover 230 is provided with a guide groove 231 extending in the up-down direction, and the floating trigger assembly 220 floats up and down along the guide groove 231. In this embodiment, two guide grooves 231 are formed in the inner side wall of the mounting cover 230, and the two floating trigger assemblies 220 are correspondingly disposed in the two guide grooves 231 one by one. Specifically, the shape of the guide slot 231 matches the shape of the floating trigger assembly 220 to further limit the floating trigger assembly 220 from floating up and down only in the direction of extension of the guide slot 231.

Further, a supporting portion 232 is convexly disposed on the inner sidewall of the mounting cover 230, a position-avoiding hole 2211 is disposed on the floating trigger assembly 220 corresponding to the supporting portion 232, and the supporting portion 232 penetrates through the position-avoiding hole 2211 and abuts against the sidewall of the water tank 200. It can be understood that, because the inner sidewall of the mounting cover 230 cannot be provided with a reinforcing rib at a position corresponding to the floating trigger assembly 220, in order to avoid the situation that the mounting cover 230 is recessed under the action of water pressure, a support 232 is provided at a position corresponding to the floating trigger assembly 220 on the inner sidewall of the mounting cover 230, and the support 232 abuts against the sidewall of the water tank 200, the situation that the mounting cover 230 is down under the hydraulic impact can be effectively prevented. In this embodiment, since the float 221 occupies a large space in the mounting cover 230, the support portion 232 is provided corresponding to the float 221, and the float 221 is provided with the space avoiding hole 2211 corresponding to the support portion 232. It should be noted that, in the water level rising direction, the length of the clearance hole 2211 is greater than that of the support portion 232, and the difference in length between the clearance hole 2211 and the support portion 232 is greater than the distance over which the float 221 needs to rise, so as to prevent the support portion 232 from restricting the rising process of the float 221.

Furthermore, a plurality of water level switches 120 are arranged, the chassis 180 is provided with a packaging box, and the plurality of water level switches 120 are packaged in the packaging box, so that the installation space of the water level switches 120 can be saved; or, the chassis 180 is provided with a plurality of packing boxes, and the plurality of water level switches 120 are packed in the plurality of packing boxes in a one-to-one correspondence manner, so that the maintenance or replacement of the water level switches 120 can be facilitated.

Further, as shown in fig. 1, the dehumidifier further includes a display device 190, the display device 190 is electrically connected to the water level switch 120, and the display device 190 is configured to display a detection result of the water level switch 120, so that a user can know the detection result and control a working state of the dehumidifier according to the detection result. Optionally, the display device 190 includes a display screen, and/or a display light. When the display device 190 includes a display screen, the display screen may be a touch screen, so that the detection result may be displayed through the display screen, and the dehumidifier may be touched through the display screen. In this embodiment, the detection result includes a water level value, whether the water tank 200 is installed, whether the water level does not exceed the minimum water level, whether the maximum water level is reached, and the like.

Further, the display device 190 may also perform alarm display according to the detection result to remind the user to pay attention to the relevant state of the water tank 200; for example, but not limited to, the display device 190 may perform an alarm display when the detection result is "the water tank 200 is not installed", "the water level does not exceed the minimum water level", and "the water level reaches the maximum water level", the alarm display may include displaying a light or displaying a character flash, displaying an alarm symbol, displaying a color change, and the like.

Further, the dehumidifier further includes a controller (not shown in the figure), the controller is electrically connected to the dehumidifying device of the dehumidifier and the water level switch 120, and the controller is configured to control the control state of the dehumidifying device according to the detection result. Typically, the controller is provided to the body 100. When the detection result is that the water tank is installed and the water level does not reach the highest water level, the controller controls the dehumidifying device to be started; and when the detection result is that the water tank is not installed or the water level reaches the highest water level, the controller controls the dehumidification device to be closed or not to be opened, so as to prevent the water in the water tank 200 from overflowing due to the fact that the dehumidification device continues to work.

Further, the dehumidifier further includes a drain pump (not shown in the drawings) to automatically drain the water tank 200 by the drain pump, thereby reducing the number of times of water pouring required by the water tank 200 and improving the convenience of use of the dehumidifier. In this embodiment, the drainage pump may be automatically controlled by the controller, and of course, the drainage pump may also be manually controlled, that is, the dehumidifier may further include a button for controlling the start and stop of the drainage pump. In order to realize the automatic control of the drainage pump, the controller is electrically connected with the drainage pump and is also used for controlling the working state of the drainage pump according to the detection result. Alternatively, the controller may control the drain pump to be activated to automatically drain the water in the water tank 200 when the detection result is that the water level reaches the maximum water level; the controller can also control the drainage pump to stop draining when the detection result is that the water level does not exceed the lowest water level, so as to avoid idle running damage of the drainage pump.
