Description

Technical Field

[0001] This utility model relates to the field of dehumidification technology, and in particular to a leak-proof dehumidifier. Background Technology

[0002] Dehumidifiers, as important devices for improving indoor humidity, are widely used in homes, offices, warehouses, basements, and other places. Their basic working principle is to lower the surface temperature of the evaporator through a refrigeration system, causing water vapor in the air to condense into liquid water. The condensate is then collected in a water tank by a water collection system. Currently, most dehumidifiers on the market adopt a modular design, where the main unit contains the core dehumidification components, and the water tank serves as an independent water storage unit. This design makes it easy for users to remove the water tank for emptying and cleaning.

[0003] However, in actual use, this detachable design reveals a common technical flaw. When the user removes the water tank, the water holes at the bottom of the main unit are immediately exposed, and at this time, there is often still residual condensate inside the unit. This residual water mainly comes from three sources: first, condensate that has not completely dripped from the evaporator surface; second, moisture accumulated on components such as the drip tray; and third, residual condensate in the pipes. This water will continue to leak from the water holes under the influence of gravity, causing ground pollution and potentially even leading to safety hazards such as electrical leakage.

[0004] Some existing products address the problem by improving structural design, such as placing the water hole at the rear of the main unit or using an angled installation. However, this only slows down the leakage rate and does not fundamentally solve the problem. Other products attempt to add auxiliary components such as flow channels or drip trays, but this increases structural complexity and makes them prone to bacterial growth. Some high-end products use electronically controlled valves, which use sensors to detect the water tank status and control the valve's opening and closing. However, this method is costly, and the electronic components are prone to failure in humid environments, making reliability difficult to guarantee. Utility Model Content

[0005] To address at least one of the problems existing in the prior art, this utility model provides a leak-proof dehumidifier.

[0006] A leak-proof dehumidifier includes:

[0007] The main unit has a dehumidification module inside, a water passage hole at the bottom of the main unit, and a valve assembly inside the water passage hole. The valve assembly includes a top cover and a shaft, with the top cover sleeved over the shaft in the middle.

[0008] A water tank is located below the main unit, and a protrusion is provided on the top of the water tank;

[0009] When the main unit is separated from the water tank, the bottom of the top cover is fitted onto the top of the water inlet;

[0010] When the main unit is assembled with the water tank, a water flow channel is formed between the bottom of the top cover and the top of the water inlet, and the shaft abuts against the boss.

[0011] In some embodiments, the inner wall of the water passage is provided with a plurality of horizontal arms, and a central ring is connected between the plurality of horizontal arms, with the shaft passing through the central ring.

[0012] In some embodiments, a pressure block is connected to the bottom of the shaft, and when the main unit is assembled with the water tank, the bottom of the pressure block abuts against the top of the boss.

[0013] In some embodiments, a spring is sleeved on the outside of the shaft, the top of the spring is fixedly connected to the bottom of the middle ring, and the bottom of the spring is fixedly connected to the top of the pressure block.

[0014] In some embodiments, the side of the shaft is recessed with an annular groove, and the top cover is engaged in the annular groove in the middle.

[0015] In some embodiments, the water passage is cylindrical, with the top of its cylindrical wall protruding from the bottom of the main unit and the bottom of the cylindrical wall being lower than the top of the boss.

[0016] In some embodiments, a sealing groove is recessed at the bottom of the top cover near the edge, and the sealing groove is adapted to the top of the cylinder wall of the water passage. When the main unit is separated from the water tank, the top cover is placed on the top of the water passage through the sealing groove.

[0017] In some embodiments, a water storage tank is recessed at the top of the top cover.

[0018] In some embodiments, the top of the water tank is recessed with a water inlet groove, the protrusion is protruding from the middle of the water inlet groove, and a plurality of water inlet holes are opened at the bottom of the water inlet groove on the outer periphery of the protrusion.

[0019] In some embodiments, a proximity switch is provided at the bottom of the main unit, the proximity switch is electrically connected to the dehumidification module, and a float is provided inside the water tank, the proximity switch is magnetically connected to the float.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] (1) This utility model achieves the automatic opening and closing function of the water passage hole through the linkage design of the top cover and the shaft.

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0033] Some embodiments of this utility model are described below with reference to the accompanying drawings.

[0034] like Figures 1 to 4 As shown, this embodiment discloses a leak-proof dehumidifier, comprising:

[0035] The main unit 1 has a dehumidification module 11 inside for dehumidifying the air; the bottom of the main unit 1 has a water passage hole 12 for draining condensate into the water tank 2; the water passage hole 12 has a valve assembly 13 inside, the valve assembly 13 includes a top cover 131 and a shaft 132, the top cover 131 is sleeved on the outside of the shaft 132, and the linkage is realized by a snap-fit ​​structure, so that the up and down movement of the shaft 132 can drive the top cover 131 to move synchronously, thereby realizing the opening and closing of the valve assembly 13;

[0036] Water tank 2 is detachably installed below the main unit 1 for collecting condensate, and the top of the water tank 2 is provided with a boss 21;

[0037] When the main unit 1 is separated from the water tank 2, the shaft 132 inside the water passage 12 automatically falls down, causing the bottom of the top cover 131 to be sleeved on the top of the water passage 12, closing the water passage 12, forming a sealed state of the valve assembly 13, and preventing the leakage of residual condensate in the main unit 1.

[0038] When the host 1 is assembled with the water tank 2, the shaft 132 abuts against the boss 21, and the boss 21 pushes the shaft 132 to move upward, causing the top cover 131 to move upward synchronously, so that a water flow channel 14 is formed between the bottom of the top cover 131 and the top of the water passage 12, maintaining the valve assembly 13 in the open state.

[0039] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further discloses that: the inner wall of the water passage 12 is provided with a plurality of radially extending horizontal arms 121, and a middle ring 122 is connected between the plurality of horizontal arms 121. The shaft 132 passes through the middle ring 122 and can slide up and down therein; the horizontal arms 121 provide a stable mounting base for the valve assembly 13, and the middle ring 122 ensures that the shaft 132 always maintains vertical movement and prevents jamming.

[0040] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further discloses that: a pressure block 1322 is connected to the bottom of the shaft 132. When the host 1 and the water tank 2 are assembled, the bottom of the pressure block 1322 abuts against the top of the boss 21 and pushes the shaft 132 upward. The pressure block 1322 increases the contact area with the boss 21 to ensure that the lifting action is stable and reliable.

[0041] like Figure 2As shown, in addition to the features of the above embodiments, this embodiment further discloses that: a spring 133 is sleeved on the outside of the shaft 132, the top of the spring 133 is fixedly connected to the bottom of the middle ring 122, and the bottom of the spring 133 is fixedly connected to the top of the pressure block 1322. When the main unit 1 is assembled with the water tank 2, the boss 21 pushes the pressure block 1322, thereby compressing the spring 133 to push the shaft 132 and the top cover 131, opening the valve assembly 13; when the main unit 1 is separated from the water tank 2, the compressed spring 133 is released, thereby pushing the pressure block 1322 and the shaft 132 to return downward, causing the top cover 131 to close the water passage 12. The spring 133 provides a stable restoring force to ensure that the valve assembly 13 can be closed in a timely and reliable manner.

[0042] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further discloses that: the side of the shaft 132 is recessed with an annular groove 1321, and the top cover 131 is engaged in the annular groove 1321 in the middle, and the engaging connection method ensures the linkage relationship between the top cover 131 and the shaft 132.

[0043] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further discloses that: the water passage 12 is cylindrical, and the top of its cylindrical wall protrudes from the bottom of the main unit 1, forming a dam structure of a certain height. Even if there is a certain amount of water in the main unit 1, it can prevent water from overflowing from the edge of the water passage 12. At the same time, the protruding part facilitates the tight closure of the valve assembly 13 with it. The bottom of the cylindrical wall is lower than the top of the boss 21, so that the condensate falls accurately into the water inlet 23 on one side of the boss 21 after passing through the valve assembly 13, preventing water from flowing onto the rest of the top of the water tank 2 and thus remaining.

[0044] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further discloses that: a sealing groove 1311 is recessed at the bottom of the top cover 131 near the edge. The sealing groove 1311 is adapted to the top of the cylindrical wall of the water passage 12. When the main unit 1 is separated from the water tank 2, that is, when the valve assembly 13 is closed, the top cover 131 covers the top of the water passage 12 through the sealing groove 1311, forming a tight fit and effectively preventing water leakage. A sealing ring can also be provided in the sealing groove 1311 to further enhance the sealing effect.

[0045] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further discloses that: a water storage tank 1312 is recessed at the top of the top cover 131. During the closing process of the valve assembly 13, the water storage tank 1312 can temporarily store a small amount of condensate that has not yet been drained, preventing this water from overflowing on the surface of the top cover 131.

[0046] like Figure 2As shown, in addition to the features of the above embodiments, this embodiment further discloses that: the top of the water tank 2 is recessed with a water inlet groove 22, the boss 21 protrudes from the middle of the water inlet groove 22, and the bottom of the water inlet groove 22 around the boss 21 is provided with a plurality of water inlet holes 23, that is, the bottom of the cylindrical wall of the water passage hole 12 extends into the water inlet groove 22, so that the condensate falls accurately into the water inlet groove 22, and then quickly disperses from the water inlet holes 23 into the water tank 2, and completely collects the condensate.

[0047] In addition to the features of the above embodiments, this embodiment further discloses that: a proximity switch is provided at the bottom of the main unit 1, the proximity switch is electrically connected to the dehumidification module 11, and a float is provided inside the water tank 2, the proximity switch is magnetically connected to the float. This water level detection mechanism ensures that when the water level in the water tank 2 reaches a set height, or when the water tank 2 is separated from the main unit 1, the dehumidification module 11 of the main unit 1 stops working, preventing excessive condensation from accumulating inside the main unit 1 and preventing the water tank 2 from overflowing, further preventing water leakage.

[0048] The working principle of this utility model is as follows:

[0049] When the main unit 1 is assembled with the water tank 2, the boss 21 on the water tank 2 pushes the pressure block 1322 upward. The pressure block 1322 drives the shaft 132 to move upward, and the shaft 132 drives the top cover 131 to move upward, thereby opening the water hole 12 to form a water flow channel 14. At this time, the condensate in the main unit 1 enters the water hole 12 through the water flow channel 14, flows downward into the water inlet tank 22, and then enters the water tank 2 for storage through the water inlet hole 23.

[0050] When it is necessary to remove the water tank 2 to empty the water, the main unit 1 and the water tank 2 are separated. At this time, the boss 21 no longer abuts against the pressure block 1322. The spring 133 resets and pushes the pressure block 1322 to move down, thereby pulling the shaft 132 and the top cover 131 down. The sealing groove 1311 of the top cover 131 fits tightly against the top of the cylinder wall of the water passage 12, closing the water passage 12. Thus, even if there is still residual condensate in the main unit 1, it will not leak out.

[0051] The beneficial effects of this utility model are as follows: The automatic opening and closing function of the water passage hole 12 is achieved through the linkage design of the top cover 131 and the shaft 132. When the water tank 2 is assembled with the main unit 1, the boss 21 pushes the shaft 132 upward, forming a water flow channel 14 between the top cover 131 and the water passage hole 12. When the water tank 2 is removed, the shaft 132 drives the top cover 131 to automatically close the water passage hole 12. This mechanical linkage mechanism responds quickly and seals reliably, fundamentally solving the leakage problem when the water tank 2 is separated and preventing leakage from the main unit 1. Using basic mechanical components such as the top cover 131, shaft 132, and spring 133, complex functional requirements are achieved through simple mechanical cooperation. The cross arm 121 and the middle ring 122 structure inside the water passage hole 12 provide stable guidance for the shaft 132, and the annular groove 1321 design ensures a reliable connection between the top cover 131 and the shaft 132. The entire structure is compact and reasonable, which ensures functionality without taking up too much internal space. The structure is simple and reasonable, and is easy to assemble and maintain, effectively reducing production and operating costs. Compared with electronic control solutions, it is not only cheaper, but also has advantages in reliability and service life in humid environments.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
