Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water level monitors, in particular to a float component, a water tank and a dehumidifier. Background Art
[0002] In modern homes and industrial environments, dehumidifiers play a vital role as an important device for controlling air humidity. The water level monitoring system is one of the core components of the dehumidifier, and its accuracy and reliability are directly related to the normal operation of the dehumidifier and user experience.
[0003] At present, the common dehumidifier water level monitoring system mainly relies on the float assembly. The system usually includes: a float with a magnet embedded inside, which can float up with the rising water level; a water tank for collecting condensed water during the dehumidification process; and a reed switch installed at an appropriate position outside the water tank. The reed switch is used to sense the position change of the magnet inside the float and transmit the signal to the control system. The control system controls the operation status of the dehumidifier according to the signal of the reed switch, such as stopping the dehumidifier when the water tank is full or starting to drain.
[0004] However, the existing float water level monitoring system has some problems in actual production:
[0005] Floats are easy to be installed incorrectly or missed: Traditional floats have a simple structure. For example, square floats are prone to being installed upside down due to the lack of clear directional instructions during mass production. This causes the workers to install the floats incorrectly, resulting in failure of the water level detection function and affecting product quality and user experience.
[0006] Problems of misinstallation and horizontal placement of floats: The existing structure cannot effectively prevent multiple floats from being mistakenly installed in the same float slot, which may lead to a decrease in the accuracy of water level detection and affect the normal operation of the dehumidifier. In addition, some float designs allow them to be placed horizontally in the float slot. In this case, the float may not work properly, resulting in failure of water level detection.
[0007] The above problems not only increase the error rate in the production process, but may also cause functional abnormalities in the dehumidifier during use, such as failure to correctly detect the water level, failure to shut down or drain in time, etc. This not only affects the user experience and product reliability, but also increases the difficulty of quality control and production costs. Utility Model Content
[0008] In order to solve the above problems, the utility model provides a float assembly, a water tank and a dehumidifier which effectively prevent the problems of reverse installation, missing installation and multiple installation of the float.
[0009] In order to achieve the above-mentioned purpose, in the first aspect, an embodiment of the present application provides a float assembly for being assembled in a float groove of a water tank, the float assembly comprising a float block and a magnet block embedded in the float block, the overall specific gravity of the float block and the magnet block is less than 1, the float block has a first side surface and a second side surface arranged opposite to each other, the magnet block is embedded in the first side surface, and a protruding structure is vertically arranged in the middle position of the second side surface, wherein the width of the protruding structure is smaller than the width of the water inlet on the side surface of the float groove, and the sum of the width of the float block and the width of the protruding structure is greater than the width of the float groove, so as to limit the installation direction of the float block.
[0010] A further solution is that the top surface of the protruding structure is flush with the top surface of the float block, and the bottom surface of the protruding structure is flush with the bottom surface of the float block.
[0011] In order to simply and effectively provide direction pointing, the protruding structure is a whole continuous rib, or a plurality of ribs arranged at intervals in a straight line.
[0012] In the second aspect, an embodiment of the present application provides a water tank, comprising a water tank body, a float groove arranged in the water tank body, and a float assembly assembled on the float groove, the float assembly being the float assembly described in any embodiment of the first aspect, and one end of the protruding structure extending into the water tank body through the water inlet of the float groove.
[0013] In order to prevent the float from being misplaced in the float groove, the width W1 of the float block is greater than the width of the water inlet and the length L1 of the float block is greater than the width W3 of the float groove.
[0014] In order to prevent the float from being placed horizontally into the float groove, the height H2 of the protruding structure is greater than the width W4 of the water inlet.
[0015] In order to avoid installing multiple floats, the height H1 of the float block is smaller than the depth H3 of the float groove, wherein 2*H1>H3.
[0016] In order to ensure that only one float can be installed normally, the float groove is detachably installed with a limit pin, and the limit pin at least partially extends to the moving path of the float block in the float groove, and the distance between the limit pin and the bottom surface of the float groove is greater than the height H1 of the float block and less than twice the height H1 of the float block.
[0017] In order to facilitate the float to move freely with the change of water level, a plurality of convex ribs are vertically arranged on the inner wall of the float groove, and the plurality of convex ribs are arranged at intervals along the circumference of the float groove; when there is water in the float groove, the side wall of the float block contacts part of the convex ribs and is spaced apart from the inner wall of the float groove to form a gap.
[0018] In order to facilitate demoulding, the radial cross-sectional area of the convex rib gradually increases along the installation direction of the float block.
[0019] In order to prevent the float assembly from shaking and generating noise when there is no water in the float tank, a support rib is provided on the bottom surface of the float tank, and the distance between the limit pin and the support rib is less than twice the height of the float block.
[0020] A further solution is that the height of the supporting ribs gradually decreases in the float groove in a direction away from the water inlet.
[0021] In a third aspect, an embodiment of the present application provides a dehumidifier, comprising the water tank described in any embodiment of the second aspect.
[0022] The float assembly, water tank and dehumidifier designed by the utility model effectively prevent the problems of reverse installation, missing installation and multiple installation of the float by setting a specific protruding structure on the float and designing a corresponding water inlet in the float groove of the water tank. This not only ensures that the float can only be installed in the correct direction, but also makes the existence of the float more obvious, which is convenient for workers to quickly identify and greatly reduces the assembly error rate; at the same time, the carefully designed size relationship eliminates the possibility of multiple floats being mistakenly installed in the same float groove, significantly improves production efficiency, reduces rework rate and quality control costs, and thus improves product reliability and user experience.

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0034] Example 1
[0035] Before introducing the float assembly 100 provided in the embodiment of the present application, the application scenario of the float assembly 100 provided in the embodiment of the present application is introduced as follows:
[0036] The float assembly 100 provided in the embodiment of the present application is mainly used in the condensation water tank of the air dehumidifier. The condensation water tank is used to collect the condensation water generated during the dehumidification process, and a reed switch is installed at an appropriate external position. The reed switch is used to sense the position change of the magnet in the float assembly 100 and transmit the signal to the control system of the dehumidifier. When the water level in the condensation water tank rises, the float assembly 100 will rise with the water level. When the water level reaches a predetermined height, the magnet in the float assembly 100 will approach the reed switch outside the water tank, triggering the reed switch to close or open, thereby sending a signal to the control system of the dehumidifier. The control system controls the working state of the dehumidifier according to the received signal, such as stopping the dehumidifier when the water tank is full or starting the drainage pump to drain water.
[0037] First, as Figures 1 to 3As shown, the float assembly 100 provided in the embodiment of the present application is used to be assembled in the float tank of the water tank, and specifically includes: a float block 10 and a magnet block 20. In this embodiment, the float block 10 can be made of a variety of lightweight materials, such as foam materials, such as polypropylene (PP) foam materials, polystyrene (EPS) foam materials, etc., or other plastic materials with a density less than water, so that the overall specific gravity of the float block 10 and the magnet block 20 is less than 1, so as to ensure that the float assembly 100 can float on the water surface to achieve water level detection; at the same time, the magnet block 20 can be embedded or bonded inside the float block 10, or it can be integrally injection molded with the float block 10. In this embodiment, the magnet block 20 is preferably assembled with the float block 10, and can enhance the stability of the overall structure of the float assembly 100, and the float block 10 and the float block 10 are assembled as an integral injection molding, which can not only enhance the overall structural strength of the float assembly 100, but also simplify the manufacturing process and reduce the production cost.
[0038] Specifically, the float block 10 has a first side surface 11 and a second side surface 12 that are arranged opposite to each other, the magnet block 20 is embedded in the first side surface 11, and a protrusion structure 30 is vertically arranged in the middle position of the second side surface 12, wherein the width of the protrusion structure 30 is smaller than the width of the water inlet on the side of the float groove, and the sum of the width of the float block 10 and the width of the protrusion structure 30 is larger than the width of the float groove, so as to limit the installation direction of the float block 10. The specific structure of the protrusion structure 30 is related to the water tank 200 described below, and its purpose is to prevent the float assembly 100 from being installed incorrectly or missing, which will be described in detail below. Of course, the protrusion structure 30 can be as follows Fig. 9 As shown, two or more protrusion structures 30 are provided, and the plurality of protrusion structures 30 are arranged with intervals therebetween.
[0039] In this embodiment, if Figure 1 and Figure 2 As shown, the magnet block 20 and the protrusion structure 30 are respectively arranged on different sides of the float block 10, which can avoid the protrusion structure 30 from affecting the function of the magnet block 20, ensure the accuracy and reliability of water level detection, and at the same time make the center of gravity of the float assembly 100 more balanced, improve the stability of the float assembly 100 in water, and thus improve the accuracy of water level detection.
[0040] In this embodiment, if Figure 1 As shown, each corner of the float block 10 and the protruding structure 30 is designed to be rounded to avoid sharp edges and corners, making the overall appearance of the float assembly 100 softer and more beautiful.
[0041] In this embodiment, if Figure 1As shown, the top surface of the protruding structure 30 is flush with the top surface of the float block 10, and the bottom surface of the protruding structure 30 is flush with the bottom surface of the float block 10. This design can ensure that the float block 10 can be raised and lowered steadily and smoothly when the water level changes, reducing the possibility of tilting or flipping.
[0042] In this embodiment, the protrusion structure 30 is a whole continuous rib, or a plurality of ribs arranged at intervals in a straight line. Figure 1 As shown, the ribs (protruding structures 30) extend along the preset installation direction of the float block 10 (vertical direction) to clearly indicate the correct installation direction of the float assembly 100, that is, when the worker puts the float assembly into the float tank of the water tank, he can easily judge whether the float assembly 100 is installed correctly by observing the direction of the ribs to avoid reverse installation. At the same time, the ribs have a simple structure and can be integrally formed with the float block 10, which is easy to design and manufacture, and can reduce the production cost of the float assembly 100. In addition, the ribs can also be designed as discontinuous structures, such as multiple ribs arranged at intervals in a straight line. The discontinuous ribs can reduce the amount of material used, thereby reducing the overall mass of the float assembly 100, making the float assembly 100 lighter and easier to float.
[0043] In a second aspect, the present application embodiment provides a water tank 200, such as Figures 4 to 7 As shown, it includes a water tank body 40, a float groove 50 disposed in the water tank body 40, and a float assembly 100 assembled in the float groove 50, wherein the float assembly is the float assembly 100 described in any embodiment of the first aspect, and one end of the protruding structure 30 extends into the water tank body 40 through the water inlet 60 of the float groove 50. The top of the water inlet 60 is open; the float groove 50 and the water tank body 40 may share at least one side wall. In one embodiment, among the four side walls of the float groove 50, the side wall opposite to the water inlet 60 is shared with the water tank body 40; in another embodiment, the float groove 50 and the water tank body 40 share two side walls.
[0044] Specifically, one end of the protruding structure 30 passes through the water inlet 60 and extends into the water tank body 40 . The length L2 of the protruding structure 30 is smaller than the width W4 of the water inlet 60 , so as to limit the installation direction of the float block 10 .
[0045] With this structural design, when the float assembly 100 is placed in the float tank 50, the protrusion structure 30 guides the worker to place the protrusion structure 30 of the float block 10 into the water inlet 60 in the correct direction, and due to size restrictions, the float block 10 can only be placed in the float tank 50 in a preset installation direction and posture, thereby preventing the float assembly 100 from being installed in reverse. Specifically, since the sum of the width W1 of the float block 10 and the width W2 of the protrusion structure 30 is greater than the width W3 of the float tank 50, if the worker If a person tries to place the float assembly 100 into the float groove 50 in the wrong direction (for example, the protruding structure 30 is facing the side away from the water inlet 60), the protruding structure 30 will be blocked by the side wall of the float groove 50 and cannot be completely placed in. Only the protruding structure 30 on the float block 10 enters the water inlet 60 on the inner wall of the float groove 50. The water inlet 60 can guide the protruding structure 30 to slide along the preset installation direction, further ensuring that the float assembly 100 is installed in the correct direction and posture.
[0046] In some embodiments, Figure 6 and Figure 7 As shown, the width W1 of the float block 10 is greater than the width W4 of the water inlet 60 and the length L1 of the float block 10 is greater than the width W3 of the float groove 50 .
[0047] Specifically, when a worker attempts to rotate the float block 10 90 degrees in a predetermined posture and place it in the float tank 50, the magnet block 20 on the float block 10 is misaligned with the reed switch outside the water tank 200, which will cause the water level detection to fail. With the above structural design, on the one hand, since the length L1 of the float block 10 is greater than the width W3 of the float tank 50, the float block 10 cannot completely enter the float tank 50, thereby forcing the worker to place the float block 10 in the float tank 50 in a preset installation posture to achieve the best foolproof effect.
[0048] In some embodiments, Figure 6 and Figure 7 As shown, the height H2 of the protruding structure 30 is greater than the width W4 of the water inlet 60 .
[0049] Specifically, when the float assembly 100 is placed horizontally, the magnet block 20 on the float block 10 may not be properly aligned with the reed switch outside the water tank 200, resulting in failure of water level detection or inaccurate detection. Therefore, by designing the height H2 of the protruding structure 30 to be greater than the width W4 of the water inlet 60, when a worker tries to place the float assembly 100 horizontally into the float groove 50, the protruding structure 30 will be blocked by the side wall of the water inlet 60 and cannot enter the water inlet 60, thereby interfering with the float block 10 and preventing it from fully entering the float groove 50, thereby effectively limiting the installation direction and posture of the float block 10, ensuring that the float block 10 can only be placed into the float groove 50 in a preset installation direction and posture (i.e., placed vertically, with the protruding structure 30 facing the water inlet 60), thereby improving the reliability and accuracy of the water level detection system.
[0050] In some embodiments, Figure 7 As shown, the height H1 of the float block 10 is less than the depth H3 of the float groove 50, wherein 2*H1>H3. In practical applications, in order to ensure that the float block 10 can move stably when the water level in the water tank body 40 changes, the depth H3 of the float groove 50 is usually designed to be greater than the height H1 of the float block 10, so as to leave a certain redundant space. However, if the depth H3 of the float groove 50 is too large, for example, more than twice the height H1 of the float block 10, it may cause workers to mistakenly put multiple float blocks 10 into the same float groove 50. When multiple float blocks 10 are in the float groove 50 at the same time, they may interfere with each other, resulting in inaccurate water level detection. Therefore, the condition 2*H1>H3 ensures that even if the worker mistakenly puts the second float block 10 into the float groove 50, the top of the second float block 10 will be exposed from the float groove 50 and cannot be completely inserted. That is, when the top of the second float block 10 is exposed from the float groove 50, it will give the worker an obvious visual prompt, reminding the worker that an assembly error has occurred and the excess float block 10 needs to be removed.
[0051] In some embodiments, Figure 5 and Figure 7 As shown, the float groove 50 is detachably mounted with a limit pin 70, the limit pin 70 at least partially extends to the moving path of the float block 10 in the float groove 50, and the distance between the limit pin 70 and the bottom surface of the float groove 50 is greater than the height H1 of the float block 10, and less than twice the height H1 of the float block 10. Specifically, the limit pin 70 is arranged in the float groove 50. On the one hand, it can prevent the float block 10 from falling out of the float groove 50 after the assembly is completed. On the other hand, even if a worker mistakenly puts multiple float blocks 10 into the same float groove 50 and is not discovered, in the subsequent assembly process of the limit pin 70, the extra float blocks 10 will interfere with the correct installation of the limit pin 70, which will prompt the worker that an installation error has occurred, thereby avoiding product quality problems.
[0052] In some embodiments, Figure 5 and Figure 6 As shown, a plurality of convex ribs 80 are vertically arranged on the inner wall of the float groove 50, and the plurality of convex ribs 80 are arranged at intervals along the circumference of the float groove 50; when there is water in the float groove 50, the side wall of the float block 10 contacts part of the convex ribs 80 and forms a gap with the inner wall of the float groove 50. With this structural design, the outer surface of the float block 10 contacts the convex ribs 80 instead of the entire inner wall of the float groove 50, which can reduce the friction resistance between the float block 10 and the float groove 50, so that the float block 10 can move up and down more smoothly with the change of water level, thereby improving the sensitivity and response speed of water level detection.
[0053] In some embodiments, Figure 6 and Figure 8 As shown, the radial cross-sectional area of the convex rib 80 gradually increases along the installation direction of the float block 10. In this way, the convex rib 80 is designed to be narrow at the top and wide at the bottom. During the demolding process, since the upper part of the convex rib 80 is narrower and the contact area with the mold is smaller, it is easier to generate an initial separation gap with the mold, making the demolding process smoother.
[0054] In some embodiments, Figure 5 and Figure 8 As shown, the bottom surface of the float groove 50 is provided with a support rib 51, and the distance between the stop pin 70 and the support rib 51 is less than twice the height H1 of the float block 10. In this way, by providing the support rib 51, when the float groove 50 is submerged in water, a gap is formed between the bottom surface of the float block 10 and the bottom surface of the float groove 50, thereby preventing the float block 10 from directly contacting the bottom of the groove, thereby reducing the movement resistance of the float block 10 at low water level, allowing it to move more flexibly and float more easily as the water level rises.
[0055] It should be noted that when the support rib 51 is provided, the vertical distance from the limit pin 70 to the support rib 51 is H4. At this time, 2*H1>H4.
[0056] In this embodiment, if Figure 5 and Figure 8 As shown, the height of the support rib 51 gradually decreases in the float groove 50 in the direction away from the water inlet 60. With this structural design, when there is no water in the float groove 50, the float block 10 will be at the lowest position, that is, in contact with the support rib 51. At this time, the inclined design of the support rib 51 will guide the float block 10 to tilt to one side, so that it is close to the inner wall of the float groove 50 (the side opposite to the water inlet 60). In this way, the float block 10 can be prevented from colliding with the inner wall of the float groove 50 when the water tank body 40 shakes, thereby effectively reducing noise and improving user experience.
[0057] In some embodiments, Figure 5 As shown, the bottom surface of the float groove 50 is an inclined surface inclined toward the opening direction of the water inlet 60. The inclined bottom surface can make it easier to discharge the accumulated water in the float groove 50, thereby preventing the accumulated water from affecting the normal operation of the float block 10 or generating odor due to the accumulated water for too long.
[0058] It should be noted that the dimensional parameters such as length, width and height mentioned in this embodiment, such as length L1, length L2, width W1, width W2, width W3, width W4, height H1, height H2, depth H3, distance H4, etc., all refer to the maximum dimensions of the corresponding components in the preset installation direction and posture.
[0059] In a third aspect, an embodiment of the present application provides a dehumidifier, comprising the water tank 200 described in any embodiment of the second aspect. The dehumidifier has all the beneficial effects of the water tank 200 described above, which will not be repeated here.
[0060] The float assembly, water tank and dehumidifier provided in this embodiment effectively prevent the problems of reverse installation, missing installation and multiple installation of the float by setting a specific protruding structure on the float and designing a corresponding water inlet in the float groove of the water tank. This not only ensures that the float can only be installed in the correct direction, but also makes the existence of the float more obvious, which is convenient for workers to quickly identify and greatly reduces the assembly error rate; at the same time, the carefully designed size relationship eliminates the possibility of multiple floats being mistakenly installed in the same float groove, significantly improves production efficiency, reduces rework rate and quality control costs, and thus improves product reliability and user experience.
