[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] A dehumidifier proposed in an embodiment of the utility model, referring to Figure 1 and Figure 2 , including a main body 100 and a water tank 200. The main body 100 includes the main functional components of the dehumidifier, such as a compressor 120 and a heat exchanger 130. The compressor 120 cooperates with the heat exchanger 130 to condense the water vapor in the indoor air, and the condensed water is collected by the water tank 200. The main body 100 also includes a shell assembly, which includes a shell and a middle partition 110 and other structures. The shell assembly is a combination of the main plates in the dehumidifier, which is used to install and protect the above-mentioned main functional components. The water tank 200 is located on one side of the middle partition 110.

[0035] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The dehumidifier includes a water level detection component 300, which is used to monitor the liquid level state of the water tank 200 to prevent excessive condensed water from overflowing the water tank 200.

[0036] Specifically, refer to Figure 3 and Figure 4 The water level detection assembly 300 includes a float 310 and a magnetic switch 320. The float 310 is magnetic and is movably arranged inside the water tank 200. The float 310 can float on the water surface of the water tank 200 and rise and fall synchronously with the rise and fall of the liquid level. The magnetic switch 320 is installed on the middle partition 110, that is, the middle partition 110 is used as a mounting plate and corresponds to the position upward from the middle of the water tank 200. The magnetic control switch 320 includes an open state and a closed state. When there is less condensed water, the magnetic control switch 320 is in an open state; when condensed water is continuously collected, the liquid level in the water tank 200 gradually rises, driving the float 310 to rise, causing the magnetic field to change. As the float 310 rises, the magnetic field strength near the magnetic control switch 320 increases; when the height of the liquid level corresponds to the magnetic control switch 320, the magnetic field strength induced by the magnetic control switch 320 is very large, causing the magnetic control switch 320 to switch to a closed state, so that the magnetic control switch 320 feeds back the induced signal to the controller. The dehumidifier also includes an alarm device, which is electrically connected to the controller, and the alarm device is used to alarm to remind the user to drain the water in time.

[0037] It should be noted that, in some other embodiments, other structures of the housing assembly may also be used to install the magnetic switch 320 , for example, the magnetic switch 320 is installed in a housing near the water tank 200 , which is not specifically limited in this embodiment.

[0038] In some embodiments of the utility model, the magnetic control switch 320 is a reed switch. Since the float 310 is magnetic, when condensed water is continuously collected, the liquid level in the water tank 200 gradually rises, driving the float 310 to rise, causing the magnetic field to change. As the float 310 rises, the magnetic field strength near the reed switch increases; when the magnetic field is strong enough, the reeds of the reed switch attract each other under the action of the magnetic field, thereby contacting each other and closing the circuit, so that current passes through the reed switch, and then the current signal is fed back to the controller. It should be noted that in some other embodiments, the magnetic control switch 320 can also be a Hall effect switch. When the float 310 rises and causes the magnetic field to change, the Hall element of the Hall effect switch will produce a voltage change, thereby changing the switch state, and then feeding back the induction signal to the controller.

[0039] In some related technologies, liquid level detection usually uses a micro switch and a float to control and detect the water level. The float follows the water level and floats up and down. When the float rises and presses against the swing arm of the micro switch, the micro switch switches the switch state, thereby providing feedback on the liquid level. However, the swing arm of the micro switch is prone to deformation during long-term use, thereby affecting the accuracy of water level monitoring; at the same time, the installation space required for the float is large, resulting in a small volume of water that can be stored in the water collection tank. In this embodiment, referring to Figure 2 and Figure 4 The float 310 has a small volume, so that the volume it occupies in the water tank 200 is small, thereby making the utilization rate of the water tank 200 higher, and the water level of the water tank 200 can be fed back through the magnetic field induction of the magnetic control switch 320 and the float 310, so that the water level monitoring can maintain a high accuracy during long-term use.

[0040] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The middle partition 110 is provided with a mounting surface 111, a first positioning portion 112, a second positioning portion 113 and a first limiting portion 114. The first positioning portion 112, the second positioning portion 113 and the first limiting portion 114 are respectively located on three side surfaces of the magnetic control switch 320, and the first positioning portion 112 and the second positioning portion 113 abut against two adjacent sides of the magnetic control switch 320. The mounting surface 111 abuts against one end surface of the magnetic control switch 320, and part of the first limiting portion 114 abuts against the other end surface of the magnetic control switch 320 away from the mounting surface 111. When the magnetic control switch 320 is mounted on the middle partition 110, the adjacent two sides of the magnetic control switch 320 are respectively abutted against the first positioning portion 112 and the second positioning portion 113, so as to determine the relative position of the magnetic control switch 320 and the mounting surface 111, so as to limit the travel range of the magnetic control switch 320 along the arrangement direction of the first positioning portion 112 and the first limiting portion 114 through the first limiting portion 114.

[0041] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4The magnetic control switch 320 is placed in the vertical direction, the two end faces of the magnetic control switch 320 are respectively the front and rear faces of the magnetic control switch 320, and the four side faces of the magnetic control switch 320 are respectively the upper, lower, left and right faces of the magnetic control switch 320, that is, the installation surface 111 is located at the rear of the magnetic control switch 320, the first positioning portion 112 abuts against the lower side of the magnetic control switch 320, the second positioning portion 113 abuts against the right side of the magnetic control switch 320, and the first limiting portion 114 is located on the upper side of the magnetic control switch 320, so that when the magnetic control switch 320 is installed, the gravity of the magnetic control switch 320 is used to make the lower side of the magnetic control switch 320 abut against the first positioning portion 112, and the right side of the magnetic control switch 320 can be abutted against the second positioning portion 113, and the travel range of the magnetic control switch 320 in the up and down direction is limited by the first limiting portion 114.

[0042] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The magnetic control switch 320 is provided with a recess 321, which is located on the side of the magnetic control switch 320 close to the first positioning portion 112 or the side close to the first limiting portion 114, so that the magnetic control switch 320 has a foolproof function. If the rear end surface of the magnetic control switch 320 is arranged in a plane, the user may easily install the magnetic control switch 320 upside down during installation, resulting in the magnetic control switch 320 being assembled incorrectly. By providing the recess 321, the user can correctly install the magnetic control switch 320 on the middle partition plate 110. In some embodiments, referring to Figure 3 and Figure 4 The mounting surface 111 is provided with a protrusion 1111 located in the recess 321 , and the protrusion 1111 is used to abut against the recess 321 , thereby supporting the upper part of the rear end surface of the magnetic control switch 320 .

[0043] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The middle partition 110 is further provided with a second limiting portion 115, which is disposed on the mounting surface 111. The magnetic control switch 320 is provided with a limiting hole 322, the axis of the limiting hole 322 is perpendicular to the mounting surface 111, and the second limiting portion 115 is passed through the limiting hole 322, so that the second limiting portion 115 limits the formation range of the magnetic control switch 320 along the left and right directions, thereby fixing the relative position of the magnetic control switch 320 and the middle partition 110. In some embodiments, refer to Figure 3The limit hole 322 is located on the side of the magnetic control switch 320 close to the first positioning portion 112 or the side close to the first limit portion 114, so that the magnetic control switch 320 has an anti-foolproof function. Since the front end surface of the magnetic control switch 320 is relatively flat, if the limit hole 322 is installed in the middle of the magnetic control switch 320, the user may easily install the magnetic control switch 320 upside down during installation, resulting in incorrect assembly of the magnetic control switch 320. By opening the limit hole 322 on one side of the magnetic control switch 320, the user can correctly install the magnetic control switch 320 on the middle partition plate 110.

[0044] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The limiting hole 322 is a strip hole, the length direction of which is perpendicular to the arrangement direction of the first positioning portion 112 and the first limiting portion 114. The second limiting portion 115 includes a positioning column, one end of which is fixedly connected to the mounting surface 111. The positioning column is passed through the strip hole and can slide along the length direction of the strip hole. At the same time, a gap can be left between the first limiting portion 114 and the edge of the magnetic control switch 320, so that the magnetic control switch 320 has a certain movable range in both the up-down direction and the left-right direction, and only three sides of the magnetic control switch 320 are restricted, so that the mounting surface 111 can be adapted to install magnetic control switches 320 of different sizes or types, thereby improving the compatibility and versatility of the middle partition plate 110 to the magnetic control switch 320.

[0045] It is understandable that in some embodiments of the present invention, reference Figure 3 The positioning column is in contact with the right side of the strip hole, so that after the magnetic control switch 320 is installed on the middle partition, the magnetic control switch 320 can be positioned in the left and right direction through the cooperation between the positioning column and the second positioning portion 113. In some embodiments, refer to Figure 3 The second limiting portion 115 is cylindrical and abuts against the side walls of the limiting hole 322 at both upper and lower sides to further position the magnetic control switch 320 in the upper and lower directions.

[0046] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The middle partition 110 is further provided with a third positioning portion 116, which is provided at the first positioning portion 112 and abuts against the end surface of the magnetic control switch 320 away from the mounting surface 111. Figure 3 and Figure 4, the third positioning portion 116 abuts against the front end surface of the magnetic control switch 320, so that the rear end surface and the front end surface of the magnetic control switch 320 are abutted respectively through the mounting surface 111 and the third positioning portion 116, so as to position the lower side of the magnetic control switch 320, and then fix the magnetic control switch 320 to the middle partition 110. It should be noted that, in some embodiments, the third positioning portion 116 can be a convex strip, which is arranged along the left and right direction of the first positioning portion 112; the third positioning portion 116 can also be a convex block, the number of the convex blocks is two, and the two convex blocks are respectively located on the left and right sides of the first positioning portion 112.

[0047] It is understandable that in some embodiments of the present invention, reference Figure 3 and Figure 4 The first limiting portion 114 includes a connecting section 1141 and a hook section 1142. The connecting section 1141 is elastic, and one end is connected to the mounting surface 111, and the other end is connected to the hook section 1142. The hook section 1142 abuts against the end surface of the magnetic control switch 320 away from the mounting surface 111. When installing the magnetic control switch 320, the lower side of the magnetic control switch 320 is first placed between the mounting surface 111 and the third positioning portion 116, and then the upper side of the magnetic control switch 320 abuts against the hook section 1142, so that The connecting section 1141 generates elastic deformation to make the hook section 1142 avoid the magnetic control switch 320. When the rear side of the magnetic control switch 320 abuts the mounting surface 111, the hook section 1142 abuts the front side of the magnetic control switch 320 using the elastic restoring force of the connecting section 1141, so that the hook section 1142 cooperates with the protrusion 1111 to position the top of the magnetic control switch 320, and then fix the magnetic control switch 320 to the middle partition 110, thereby realizing the rapid installation of the magnetic control switch 320. At the same time, the connecting section 1141 and the first positioning portion 112 are respectively located on the upper side and the lower side of the magnetic control switch 320, so as to limit the travel range of the magnetic control switch 320 in the up and down directions.

[0048] It is understandable that in some embodiments of the present invention, reference Figure 4 and Figure 5 The water tank 200 has a groove 210 for accommodating the float 310, and the float 310 can float up and down along the length of the groove 210. A third limiter is provided at the top of the groove 210, and the third limiter is used to prevent the float 310 from leaving the groove 210. In some embodiments, referring to Figure 4 The third limiting portion may be a buckle 220, which is engaged with the top of the groove 210, thereby limiting the formation range of the float 310 in the up-down direction. It is understandable that in some other embodiments, the third limiting portion may also be a limiting block, which is disposed on one side of the groove 210, and which can abut against the float 310, thereby limiting the formation range of the float 310 in the up-down direction.

[0049] It is understandable that in some embodiments of the present invention, reference Figure 4 and Figure 5 The inner wall of the groove 210 is provided with a guide rib 211 for reducing the contact area between the groove 210 and the float 310. The guide rib 211 is arranged in the up-down direction. When the float 310 floats up and down, the contact area between the float 310 and the groove 210 is reduced by the provision of the guide rib 211, thereby reducing the resistance of the float 310 when floating, and reducing the situation where the float 310 is stuck due to excessive friction. In some embodiments, each side of the groove 210 is provided with a guide rib 211, so that when the float 310 floats up and down, the float 310 only contacts the guide rib 211, thereby further reducing the contact area between the float 310 and the groove 210, reducing the resistance of the float 310 when floating, and making the float 310 float more smoothly.

[0050] It is understandable that in some embodiments of the present invention, reference Figure 4 and Figure 5 The float 310 is provided with guide portions 311 at both ends. The width of the guide portions 311 decreases as it moves away from the middle of the float 310. The guide portions 311 are used to guide the float 310 to float up and down, thereby reducing the possibility that the float 310 is stuck due to large resistance. Figure 5 The guide portion 311 is arranged in an arc shape, and the guide portions 311 are arranged at both the upper and lower ends of the float 310, so that the float 310 is arranged in a runway shape. Therefore, in the process of the float 310 floating up and down, the guide portion 311 arranged in an arc shape can reduce the water resistance, so that the float 310 floats more smoothly.

[0051] It is understandable that in some embodiments of the present invention, reference Figure 2 The main body 100 is provided with a receiving chamber 400 for receiving the water tank 200. The receiving chamber 400 is arranged at the bottom of the main body 100. A mounting opening is arranged on one side of the receiving chamber 400. The water tank 200 can be installed or removed from the receiving chamber 400 through the mounting opening. When the water tank 200 is full of condensed water, the user can pull the water tank 200 from the mounting opening to remove the water tank 200 from the receiving chamber 400. After draining the condensed water, the water tank 200 can be installed in the receiving chamber 400 through the mounting opening. In this embodiment, referring to Figure 2, the installation port is arranged at the rear side of the accommodating chamber 400. Since the compressor 120 is arranged at the front side of the accommodating chamber 400, the installation port is arranged at the rear side of the accommodating chamber 400 to facilitate the user to disassemble and assemble the water tank 200. At this time, the float 310 is arranged at the side of the water tank 200 close to the magnetic control switch 320, so that the float 310 can be close to the magnetic control switch 320. It should be noted that the installation port can also be arranged at the left or right side of the accommodating chamber 400. At this time, the float 310 is arranged at the side of the water tank 200 close to the magnetic control switch 320, so that the float 310 can be close to the magnetic control switch 320.

[0052] It is understandable that in some embodiments of the present invention, reference Figure 4 and Figure 5 , a cover 230 is provided on the top of the water tank 200, and the cover 230 is used to reduce the overflow of the water tank 200 when the user pulls out the water tank 200. A buckle 231 is provided on the edge of the cover 230, and the cover 230 is buckled with the water tank 200 through the buckle 231 to block the top of the water tank 200, thereby reducing the overflow of the water tank 200; at the same time, by providing the buckle 231, the user can quickly disassemble and assemble the cover 230, so as to facilitate the cleaning of the inside of the water tank 200. In some embodiments, the cover 230 is provided with a drain port. When the alarm device reminds the user that the water tank 200 is full of condensed water, the user can drain the condensed water from the drain port without disassembling the cover 230, thereby simplifying the drainage steps.

[0053] The implementation principle of the embodiment of the present application is as follows: when installing the magnetic control switch 320, first place the lower side of the magnetic control switch 320 on the first positioning portion 112, and the right side of the magnetic control switch 320 abuts against the second positioning portion 113 to determine the relative position of the lower side of the magnetic control switch 320 and the middle partition 110 in the front-to-back direction; then abut the upper side of the magnetic control switch 320 against the hook section 1142, so that the connecting section 1141 generates elastic deformation to enable the hook section 1142 to avoid the magnetic control switch 320. When the rear side of the magnetic control switch 320 abuts against the mounting surface 111, the hook section 1142 uses the elastic restoring force of the connecting section 1141 to The front side of the magnetic control switch 320 is abutted, so that the hook section 1142 cooperates with the protrusion 1111 to position the top of the magnetic control switch 320, and further determines the relative position of the magnetic control switch 320 and the middle partition 110 along the front-to-back direction; at the same time, the second limiting portion 115 cooperates with the second positioning portion 113 to position the magnetic control switch 320 along the left-right direction, and the second limiting portion 115 abuts against the side walls on the upper and lower sides of the limiting hole 322 to further position the magnetic control switch 320 along the up and down direction, so that the magnetic control switch 320 is fixed to the middle partition 110, thereby realizing the rapid installation of the magnetic control switch 320.

[0054] At the same time, the connecting section 1141 and the first positioning portion 112 are respectively located on the upper side and the lower side of the magnetic control switch 320, so as to limit the travel range of the magnetic control switch 320 in the up-down direction, and the second limiting portion 115 is penetrated through the limiting hole 322 to limit the travel range of the magnetic control switch 320 in the left-right direction. Since a gap can be left between the first limiting portion 114 and the edge of the magnetic control switch 320, the magnetic control switch 320 has a certain movable range in the up-down direction; at the same time, the positioning column can slide along the strip hole, so that the magnetic control switch 320 has a certain movable range in the left-right direction, and only three sides of the magnetic control switch 320 are restricted, so that the installation surface 111 can be adapted to install magnetic control switches 320 of different sizes or types, thereby improving the compatibility and versatility of the dehumidifier with the magnetic control switch 320.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
