Abstract
Description
Technical Field
[0001] This utility model relates to the field of dehumidifier technology, and in particular to an interchangeable multi-functional drainage structure. Background Technology
[0002] With the improvement of people's living standards, dehumidifiers have entered people's lives and work. Dehumidifiers are developed for humid and harsh environments. They are equipped with heat exchangers that can liquefy water vapor in the air, thereby effectively improving the humid living and production environment and bringing it to an ideal state. They can also remove mold caused by humid environments. Existing household dehumidifiers and industrial dehumidifiers are widely used in all aspects of production and life, creating a comfortable, dry and quiet modern living space for users.
[0003] like Figure 1 As shown, the traditional dehumidifier drainage structure includes a water tray 1, a drain pipe 2 installed in the water tray 1, and a drain interface 3 connected to the drain pipe. The drain pipe 2 is usually horizontally installed in the water tray 1, and one end of the drain pipe 2 extends out of the water tray 1. The drain interface 3 has an external thread structure on its outer surface, and a silicone plug 31 is fitted onto the drain interface 3. The silicone plug 31 is compatible with the drain interface 3. However, in order to prevent water leakage from the drain interface, most traditional dehumidifiers are designed to use silicone plugs to seal the drain interface. Although this structure can prevent water leakage, the simplistic structure makes it impossible to meet the drainage needs of multiple uses.
[0004] For example, in some homes with carpets, when a traditional dehumidifier drains water from its external drain outlet, the silicone plug 31 is removed first. If the dehumidifier is running or there is still moisture on it, water will overflow from the drain outlet 3, wetting the floor or carpet and affecting the user experience. At the same time, when the water in the drip tray 1 is full and drains water from the drain pipe 2, because the drain pipe 2 is horizontal, some water can easily flow back into the machine, causing high internal pressure and potentially damaging the machine. Utility Model Content
[0005] In order to address the technical deficiencies mentioned in the background section, the purpose of this utility model is to provide an interchangeable multi-functional drainage structure that combines two or more drainage methods and is convenient and quick to use.

The plug-in part extends outward beyond the drain cover, and the plug-in part and the snap-fit part are integrally formed.
[0017] Preferably, the drainage connector is further provided with an O-ring, which is located between the mounting cavity and the connecting part.
[0018] Preferably, the sealing assembly includes a sealing head, a connecting band, and a retaining ring. The sealing head, connecting band, and retaining ring are integrally formed, and the sealing head is adapted to the drain hole of the quick-connect fitting.

[0036] The following is in conjunction with the appendix Figure 1-8The present invention provides a more detailed description of an embodiment of an interchangeable multifunctional drainage structure.
[0037] An interchangeable, multi-functional drainage structure, such as Figures 2 to 4 As shown, the device includes a drain cover 4 connected to the outside of the drain interface 3 of the dehumidifier, a drain connector 5 connecting the drain interface 3 of the dehumidifier and the drain pipe 2, and a quick-connect fitting 6 sealing the drain interface 3 of the dehumidifier. The drain cover 4 has an internal thread on its inner wall and is threaded to the drain interface 3 through the internal thread. The drain cover 4 also has a sealing component 7 for sealing the drain interface 3. One end of the drain connector 5 extends into the drain pipe 2 of the dehumidifier, and the other end is fastened to the drain cover 4. The quick-connect fitting 6 has a hollow drain hole 64 that communicates with the drain pipe 2. One end of the quick-connect fitting 6 is detachably connected to the drain connector 5, and the other end extends outward from the drain interface 3.
[0038] Specifically, the drainage connector 5 extends into the drainage pipe 2, making the drainage pipe 2, drainage hole 64, and drainage joint form a single channel, facilitating rapid water discharge and preventing overflow or backflow. Furthermore, the quick-connect connector 6 and drainage connector 5 are designed separately, allowing for easy switching between different types of external quick-connect connectors 6 to adapt to various usage scenarios. The quick-connect connector 6 can also be used for direct-insertion drainage or external drainage. Direct-insertion drainage can be replaced with pagoda-style external drainage or other suitable drainage connectors, giving the drainage structure of this invention multiple combination options. It is not only simple in structure and easy to use, but also eliminates the need to remove the drainage cap 4 or silicone plug. It is also compatible with traditional direct-drainage methods, i.e., removing the silicone plug for direct drainage, providing convenience for customers. In addition, the drainage cap 4 is threaded onto the drainage interface 3, with a simple and convenient design and smooth unscrewing mechanism, improving the user experience.
[0039] Among them, such as Figure 5 , 6As shown, the sealing assembly 7 includes a sealing head 71, a connecting strap 72, and a retaining ring 73. The sealing head 71, connecting strap 72, and retaining ring 73 are integrally molded, and the sealing head 71 is adapted to the drain hole 64 of the quick-connect connector 6. The two ends of the connecting strap 72 are connected to the sealing head 71 and the retaining ring 73 respectively. The retaining ring 73 is snapped onto the drain cover 4. The sealing head 71 is made of rubber. When the dehumidifier is running, the sealing head 71 will be inserted into the drain hole 64 of the quick-connect connector 6, thereby preventing water from flowing out of the drain hole 64. In order to prevent the sealing head 71 from being easily lost, one end of the sealing head 71 is connected to the retaining ring 73 through the connecting strap 72, and the retaining ring 73 is snapped onto the drain cover 4, so that after the sealing head 71 is used, it can hang on the drain cover 4 and is not easy to fall off, thus achieving a good foolproof effect.
[0040] It is worth mentioning that the drainage structure of this utility model not only meets the basic dehumidification needs of household users and dehumidification scenarios, but also provides convenient additional functional designs, making it a multi-functional, multi-purpose, and efficient dehumidifier that meets different needs, making it more comfortable for people to use.
[0041] In this embodiment, as Figure 4 As shown, the drainage connector 5 includes a mounting part 51 and a connector part 52. The mounting part 51 has a central hole 511 near its center position. The central hole 511 and the drainage hole 64 are located on the same axis and communicate with each other. The diameter of the connector part 52 is larger than the diameter of the snap-fit part 62, so that the drainage connector 5 is formed into a T-shaped structure. The connector part 52 has a receiving cavity 521 inside, and the inner wall of the receiving cavity 521 is set with an internal thread structure 522. The outer surface of the mounting part 51 near the drainage pipe 2 has a first annular segment 512 recessed downward. The first annular segment 512 has a first sealing ring 8 inside, which abuts against the inner wall of the drainage channel. The outer surface of the other end of the mounting part 51, which is backed by the drainage interface 3, has a second annular segment 513 recessed downward. The second annular segment 513 has a second sealing ring 9 inside, which abuts against the inner wall of the drainage interface 3.
[0042] Specifically, due to the increased diameter at the connection between the drain pipe 2 and the drain interface 3, a water storage platform is easily formed, causing water to overflow from the water outlet platform during drainage. To solve this problem, this utility model extends the installation part 51 of the drain connector 5 into the drain pipe 2, so that the central hole 511 and the drain pipe 2 are on the same straight line and interconnected. A first sealing ring 8 and a second sealing ring 9 are respectively provided in the first annular section 512 and the second annular section 513 outside the installation part 51. The first sealing ring 8 and the second sealing ring 9 abut against the gap between the drain pipe 2 and the installation part 51, thereby isolating water from overflowing from the water storage platform and effectively preventing water from flowing back into the dehumidifier.
[0043] In this embodiment, a flange 523 is provided on the outer surface of the connector 52, and a snap-fit is formed between the flange 523 and the top of the connector 52. The flange 523 can increase the contact area between the connector 52 and the drain pipe 2, and a buckle 41 is provided around the inner edge of the drain cover 4. The vertical cross-section of the buckle 41 is in the shape of a barb, and the buckle 41 is engaged with the snap-fit on the drain connector 5. The buckle 41 and the snap-fit make the connection between the drain connector 5 and the drain cover 4 simpler and more convenient. At the same time, after the buckle 41 and the snap-fit are engaged, the connection is not easy to fall off, and it also facilitates subsequent disassembly and maintenance.
[0044] In this embodiment, as Figure 6 As shown, the drainage connector 5 is also provided with an O-ring seal 10, which is located between the mounting cavity and the connecting part 61.
[0045] Specifically, the O-ring 10 can seal and isolate water flow. When the quick-connect fitting 6 is inserted into the drain connector 5, it is threadedly connected to the internal thread structure 522 of the mounting part 51 through the external thread structure 611 of the connecting part 61. Since there is a gap between the threads, when the water flows outward from the drain interface 3 through the mounting cavity during drainage, some water will flow out from the gap between the threaded connection between the connecting part 61 and the mounting cavity, which can easily lead to water leakage in the drainage structure. Therefore, by setting the O-ring 10 in the mounting cavity of the drain connector 5, the O-ring 10 can fit and seal the gap between the mounting cavity and the connecting part 61, so that the water cannot flow out from the gap of the threaded structure, thereby effectively preventing water from overflowing through the quick-connect fitting 6 and the drain connector 5 during operation.
[0046] In this embodiment, as Figure 7 , 8 As shown, the quick-connect connector 6 includes a connecting part 61, a snap-fit part 62, and a plug-in part 63. The outer surface of the connecting part 61 is provided with an external thread structure 611, which is adapted to the internal thread structure 522. The connecting part 61 is threadedly connected to the receiving cavity 521. The snap-fit part 62 is located between the connecting part 61 and the plug-in part 63, and one end of the snap-fit part 62 abuts against the connector part 52. The plug-in part 63 extends outward beyond the drain cover 4, and the plug-in part 63 and the snap-fit part 62 are integrally formed structures.
[0047] Specifically, the connecting part 61 adopts an external thread structure 611, which makes it easier to disassemble and assemble, and the length of the connecting part 61 is equal to the depth of the installation cavity; the diameter of the snap-fit part 62 is larger than the diameter of the drainage connector 5, so that the quick-connect connector 6 can be quickly positioned and installed on the drainage connector 5, and the snap-fit part 62 can also seal the gap between the drainage interface 3 and the quick-connect connector 6 to prevent water leakage; the type of the plug part 63 can be selected according to actual usage needs. This utility model provides two common types: straight-tube plug and inverted plug. During use, users can directly connect the straight-tube drain pipe to the quick-connect connector 6 for quick drainage, or replace the quick-connect connector 6 with other types of connectors to easily adapt to various usage scenarios.
[0048] In this embodiment, the connection between the quick-connect fitting 6 and the drainage connector 5 is one of threaded, snap-fit, or magnetic connection.
[0049] Specifically, this utility model adopts an interchangeable multi-functional drainage structure design. During use, users can directly connect the straight-insertion drain pipe to the quick-connect connector 6 for quick drainage, or replace the quick-connect connector 6 with other types of connectors to easily adapt to various usage scenarios. When replacing the quick-connect plug, since the quick-connect connector 6 and the drainage connector 5 are detachably connected, the specific connection method adopts one of threaded, snap-fit, or magnetic connection, making it easier and faster to replace the quick-connect connector.
[0050] The working principle of this utility model:
[0051] When installing the dehumidifier's drainage structure, firstly, assemble the first sealing ring 8 and the second sealing ring 9 onto the drainage connector 5 through the pre-reserved grooves on the mounting part 51; then, fasten the buckles on the drainage connector 5 with the snaps 41 on the inner edge of the drainage cover 4, thereby quickly and securely connecting the drainage connector 5 to the drainage cover 4; then, place the O-ring 10 into the mounting cavity of the drainage connector 5, and connect the quick-connect fitting 6 to the drainage connector 5 via a threaded structure. During connection, the quick-connect fitting 6 will engage the O-ring 10. 0 is pressed into the drain connector 5; finally, the pump water connection is inserted into the drain pipe 2, and the drain cover 4 is tightened onto the drain interface 3, thus completing the installation of the drain structure; when draining, simply remove the sealing plug 71 that is sealed on the drain hole 64, and the quick connector 6 can be disassembled and replaced according to usage needs. It not only meets the basic dehumidification needs of household users and dehumidification scenarios, but also provides convenient additional functions, making it a multi-functional, multi-purpose, and efficient dehumidifier that meets different needs, making it more comfortable for people to use.
