This water level detection method has low detection accuracy, cannot detect water level in real time, and has a relatively complex structure. Other electrical appliances or machines that use liquid level switches, such as washing machines, humidifiers, water heaters, etc., use electrode detection, pressure sensor detection, etc. This detection method can detect the water level in real time, but because the container cannot be separated from the electrical appliance itself, and the existing dehumidifier water tank needs to be separated from the machine after it is full of water, and the water needs to be taken out separately to pour the water. Therefore, the water level detection structure used in the existing washing machines, humidifiers, and water heaters cannot be directly applied to the dehumidifier water tank.

[0036] See also Figures 1 to 11As shown, according to an embodiment of the present invention, a dehumidifier water tank water level detection structure is provided, including a dehumidifier body 1 and a water tank 2, wherein the dehumidifier body 1 serves as an assembly carrier of the water tank 2, and is also a general term for other main structural components of the dehumidifier except the water tank 2 (such as a casing, a heat exchanger, a fan, a compressor, etc.), the water tank 2 is detachably connected to the dehumidifier body 1, a liquid level detection component 3 is provided in the water tank 2, and the liquid level detection component 3 can be, for example, an existing pressure sensor for real-time detection of the water level in the water tank 2, the liquid level detection component 3 has an electrical input terminal 31, and an electrical output terminal 11 is provided on the dehumidifier body 1, the electrical input terminal 31 is magnetically connected to the electrical output terminal 11, and at least one of the electrical input terminal 31 and the electrical output terminal 11 has a magnetic attraction ability, so that when the water tank 2 is assembled at a predetermined position of the dehumidifier body 1, the two can be magnetically connected as a whole. In this technical solution, by setting a liquid level detection component in the water tank 2, the water level of the water tank is detected in real time. At the same time, by magnetically connecting the electric input terminal 31 of the liquid level detection component with the electric output terminal 11 fixed on the dehumidifier body 1, the working condition requirement of the water tank body being taken out from the dehumidifier body is met. That is, the technical solution of the present invention can realize the actual detection of the water level while ensuring that the water tank 2 can be taken out from the dehumidifier body 1 when the water is full (when the water level reaches the preset water level). The aforementioned electric input terminal 31 and the electric output terminal 11 match each other in signal transmission so as to be able to transmit the detection data of the liquid level detection component 3 to the control component of the dehumidifier. Of course, the data transmitted can also include other types of data, such as the connection status data of the two.

[0037] Specifically, Fig.11 As shown, the electrical input terminal 31 is fixedly connected to the water tank 2, and the electrical output terminal 11 is arranged on the dehumidifier body 1 (which serves as the electrical input component of the liquid level detection component 3). Specifically, for example, a corresponding notch 121 is opened at the corresponding position of the water receiving tray 12 and the electrical input terminal 31, and the electrical output terminal 11 is fixedly installed in the notch 121. Since the electrical input terminal 31 and the electrical output terminal 11 are connected in a magnetic attraction manner, when the user takes out the water tank 2, the electrical input terminal 31 and the electrical output terminal 11 can be easily separated without causing any obstacles to the removal process of the water tank 2. This method is particularly simple in design and low in cost, but has shortcomings in reliability. For example, when the water level in the water tank 2 is high and fluctuates, it is very easy to splash onto the magnetic attraction contact surface of the electrical input terminal 31, causing faulty connections such as leakage, thereby causing the dehumidifier to passively shut down.

[0038] As a more preferred embodiment, preferably, a carrier 4 carrying the electrical input terminal 31 is further provided in the water tank 2, the carrier 4 is located at the top of the water tank 2, and when the water level in the water tank 2 reaches a certain height, the carrier 4 can float with the fluctuation of the water in the water tank 2. In this technical solution, by arranging the electrical input terminal 31 on the carrier 4, the carrier 4 can float with the fluctuation of the water under the above conditions, which can effectively reduce the probability of faulty connection caused by splashing water during the transfer process of the water tank 2 being full of water, thereby improving the user experience of the dehumidifier.

[0039] Furthermore, the water tank 2 has a tank cover 21, and a water drop channel 211 is constructed on the tank cover 21. The condensed water in the water receiving tray 12 of the dehumidifier is guided to the water tank 2 through the water drop channel 211 for accumulation. The top of the water tank 2 has an opening, that is, the tank cover 21 does not completely cover the top opening of the water tank 2. At this time, the carrier 4 is connected to the tank cover 21 and is within the opening range. Specifically, the carrier 4 includes a floating platform 41. A connecting ring 212 is connected to the side wall of the tank cover 21. The floating platform 41 is connected to the connecting ring 212 with a gap. When the water level in the water tank 2 is at the first position, the connecting ring 212 keeps the floating platform 41 on the connecting ring 212. When the water level in the water tank 2 is at the second position, the floating platform 41 can float on the water surface, wherein the second position is higher than the first position, and the electrical input terminal 31 is located at the upper part of the floating platform 41. In this technical solution, on the one hand, the connecting ring 212 is used to make necessary restrictions on the up and down floating stroke of the carrier 4, and on the other hand, the connecting ring 212 is set on the side wall of the box cover 21 instead of the top wall, which can reduce the height dimension of the water level detection structure and thus reduce the height design of the dehumidifier. In this technical solution, it can be understood that the height of the floating platform 41 is limited by the connecting ring 212. In this way, when the water level in the water tank 2 is low, the floating platform 41 is objectively located on the connecting ring 212, and is not in a floating state. Only when the water level reaches a preset height, the floating platform 41 is floated to be lower than the aforementioned disadvantages that may be caused by the fluctuation of the water surface.

[0040] As a specific structural type of the floating platform 41, preferably, the floating platform 41 has a frustum body 411 (larger at the top and smaller at the bottom) located at the upper part of the connecting ring 212, a stop ring 412 located at the lower part of the connecting ring 212, and a limit ring 413 corresponding to the connecting ring 212, and the frustum body 411 and the stop ring 412 are connected as a whole through the limit ring 413. In this technical solution, the frustum body 411 is located at the upper part of the floating platform 41 as a bearing platform for the electrical input terminal 31, and the stop ring 412 is located at the lower part of the floating platform 41 as a limiting component for limiting the maximum floating displacement of the floating platform 41, and the height of the limit ring 413 (in the axial direction of the floating platform 41) limits the maximum and minimum floating displacements of the floating platform 41, and it is designed to match the connecting ring 212. The connection ring 212 is specifically designed as a U-shaped guide rail structure, and its opening side is detachably connected to the side wall of the box cover 21 with a mounting ear seat (for example, through the assembly positioning method of a pin shaft and a retaining spring).

[0041] Furthermore, the floating platform 41 is also provided with a sleeve 414, which extends along the axial direction of the floating platform 41, specifically, for example, on the axis of the floating platform 41, so as to ensure the stability of the posture of the floating platform 41 when the water surface fluctuates. The liquid level detection component 3 also has a connecting cable 33 connected between its electrical input terminal 31 and the detection head 32, and the connecting cable 33 passes through the sleeve 414. It can be understood that at this time, the electrical input terminal 31 and the detection head 32 are respectively located at the two ends of the sleeve 414, wherein the electrical input terminal 31 is located at one end of the sleeve facing the electrical output terminal 11, and the detection head 32 is located at one end close to the bottom of the water tank 2. Preferably, the outer periphery of the sleeve 414 is provided with a water trough 415 to effectively prevent water from accumulating on the upper part of the frustum body 411.

[0042] The liquid level detection component 3 can detect the real-time water level in the water tank 2 in real time during normal operation, and after being set, it can also send a corresponding high water level warning signal when the water level in the water tank 2 reaches the warning water level. However, in some extreme cases, this detection function may be destroyed. In this case, if the dehumidifier cannot be shut down in time, the water in the water tank 2 will overflow. In order to prevent this phenomenon from occurring, preferably, the dehumidifier water tank water level detection structure also includes a float 5. The float 5 has a low point position corresponding to the first position and a high point position corresponding to the second position. The float 5 can be controlled by the water level change in the water tank 2 to change between the low point position and the high point position (such as Figure 8As shown, the float 5 in the dotted line state is at a high point position, while the float 5 in the solid line state is at a low point position). When the float 5 is at the high point position, the electric input terminal 31 and the electric output terminal 11 are disconnected from the magnetic attraction. In this technical solution, the arrangement of the float 5 can mechanically disconnect the magnetic attraction connection between the electric input terminal 31 and the electric output terminal 11 when the float 5 is at a high point position, that is, when the water level in the water tank 2 reaches a state where the dehumidifier must be stopped, so as to control the dehumidifier to stop.

[0043] Specifically, the float 5 is pivotally connected to the box cover 21 and can swing around the pivot point of the float 5 between the low point and the high point. The end of the float 5 away from the pivot point is provided with a first cable embedding part 51, and the connecting cable 33 is fixedly embedded in the first cable embedding part 51. In fact, at this time, the float 5 objectively realizes a lever, which uses the pivot point as a fulcrum and the part in contact with water as a force application point, and the first cable embedding part 51 is ultimately used to control the tension of the connecting cable 33.

[0044] Furthermore, a float swing limit block 213 is also provided on the box cover 21, which is used to limit the low point position of the float 5. For example, in the present invention, it is set on the side wall of the box cover 21, and it is expected that it can limit the low point position of the float 5 to be horizontal; and / or, a second cable embedding part 214 is also provided on the box cover 21, and the first cable embedding part 51 is located on the side of the connecting cable 33 close to the electrical input terminal 31, and the second cable embedding part 214 is located on the side of the connecting cable 33 close to the detection head 32. At this time, the design of the second cable embedding part 214 can, on the one hand, ensure the positioning and guidance of the arrangement of the connecting cable 33 in the water tank 2, and on the other hand, prevent the weight of the detection head 32 from being directly applied to the float 5, resulting in a hysteresis in the float 5 controlling the electrical input terminal 31 and the electrical output terminal 11 to disengage the magnetic attraction connection.

[0045] The electrical output terminal 11 and the electrical input terminal 31 may be existing commercially available parts. However, in terms of specific selection, preferably, the electrical output terminal 11 is provided with a waterproof detection ring 111 and a signal transmission ring 112, and the corresponding electrical input terminal 31 is provided with a waterproof detection contact 311 and a signal transmission contact 312 corresponding to the waterproof detection ring 111. When water enters the waterproof detection ring 111, it can be detected by the waterproof detection contact 311. The pairing of the electrical output terminal 11 and the electrical input terminal 31 can detect their own connection status in real time, and further determine whether the water tank 2 is connected in place when it is reassembled in the dehumidifier body 1 after being taken out. The pairing design of the signal transmission ring 112 and the signal transmission contact 312 is based on the transmission of water level data signals and the supply of electrical energy.

[0046] According to an embodiment of the present invention, there is further provided a dehumidifier, comprising a water tank water level detection structure, wherein the water tank water level detection structure is the above-mentioned dehumidifier water tank water level detection structure.

[0047] According to an embodiment of the present invention, a dehumidifier control method is also provided, which is used to control the above-mentioned dehumidifier, including:

[0048] Acquire the connection status between the electric input terminal 31 and the electric output terminal 11, wherein the connection status includes a faulty connection and a normal connection, wherein the faulty connection includes any one of a misaligned connection, water leakage, and electric leakage. It can be understood that the aforementioned normal connection is a concept relative to the faulty connection, which means that the dehumidifier can normally perform subsequent dehumidification work;

[0049] When the connection state is a normal connection, power is supplied to the liquid level detection component 3, and the real-time liquid level acquired by the liquid level detection component 3 is acquired;

[0050] When the connection state is a fault connection, a fault alarm signal is issued.

[0051] Furthermore, it is determined whether the real-time liquid level acquired by the liquid level detection component 3 reaches a preset warning water level. If the preset warning water level is reached, a water level too high prompt signal is issued.

[0052] Preferably, when a water level over-high warning signal is issued, it is determined whether a high water level shielding signal is received. The high water level shielding signal may be, for example, an ignore button provided on the dehumidifier body. When the user clicks the ignore button, it means that the user is aware that the water level in the water tank 2 has reached a preset high water level and will overflow after a period of operation. However, the user is fully aware of the subsequent potential risks and has prepared corresponding corresponding plans. For example, the user actively handles the situation after a few minutes. At this time, if a high water level shielding signal is received, the dehumidifier is controlled to continue to operate. It can be understood that due to the corresponding design of the float 5 of the present invention, when it reaches the overflowing water level, the float 5 will mechanically disconnect the magnetic attraction connection between the electrical input terminal 31 and the electrical output terminal 11, thereby triggering the control of the dehumidifier to stop operating. Of course, if a high water level shielding signal is not received, there is a lack of manual intervention by the user at this time, and continuing to operate for too long will cause overflowing. At this time, preferably, the dehumidifier is controlled to stop operating after continuing to operate for a first preset time (for example, a few minutes, which may also be zero, i.e., stopping the operation immediately).

[0053] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
