Description

Technical Field

[0001] The utility model belongs to the technical field of water tanks, and in particular relates to a waterproof water inlet structure. Background Art

[0002] Home insulated water tanks are designed to efficiently store and insulate hot or cold water. These water tanks usually consist of three main parts: the inner tank, the insulation layer, and the outer shell. The inner tank is usually made of iron or stainless steel and is responsible for storing hot or cold water; the insulation layer is used to reduce heat loss and maintain water temperature; and the outer shell provides waterproof and corrosion-resistant functions. In addition, the outer shell is wrapped with copper tubes or aluminum microchannels as the condensing heat exchanger of the heat pump water heater, transferring the heat of the high-temperature and high-pressure refrigerant generated by the compressor to the water in the inner tank to achieve heating. The water tank also contains multiple water inlets, such as water inlet, water outlet, sewage outlet, pressure relief valve outlet, and magnesium rod outlet, which penetrate the outer shell. If the waterproof measures are not appropriate, water may penetrate into the inner shell from these parts. Due to the different materials of components such as the inner tank, copper tube, and microchannel, when these different metal materials come into contact with water, electrochemical corrosion, that is, galvanic cell reaction, may occur, which may cause corrosion and perforation of the inner tank or heat exchanger, and ultimately damage the entire water tank system.

[0003] To avoid this situation, some insulated water tanks have a water tray on the top of the inner tank. This water tray is located above the compressor and fin heat exchanger to collect condensed water from these components and related pipes and rainwater that may penetrate. In this way, the water tray can prevent water from flowing directly to the outer surface of the inner tank, thereby reducing the risk of electrochemical corrosion between different metal materials due to contact with water. However, the water tray cannot completely collect all the water, and there is still a possibility that water will flow down from the edge of the outer shell and enter the inside of the water tank through the water outlet.

[0004] Therefore, in addition to using a water tray, it is also necessary to design a waterproof structure at the water outlet to ensure the sealing of the outer shell and prevent water penetration, thereby protecting the long-term stable operation of the entire water tank system. Utility Model Content

[0005] The utility model aims to provide a waterproof structure of a water outlet, aiming to solve the problems raised in the background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A waterproof water inlet structure is arranged on a pipe joint and is used to seal the gap formed between the pipe joint and a water tank shell. The structure comprises an annular body, wherein the annular body has a plug-in end and a mounting end, the plug-in end is provided with a reverse curved portion, the plug-in end penetrates into the water tank shell to sleeve the pipe joint and clamp the outer circumference of the pipe joint through the reverse curved portion, the mounting end extends outwardly along the circumferential direction and is provided with a supporting portion, the mounting end sleeves the end of the pipe joint and abuts against the water tank shell through the supporting portion.

[0008] As a preferred technical solution of the utility model, at least one first water-blocking ring is provided in the inner circumference of the reverse curved portion.

[0009] Furthermore, two first water-blocking rings are provided in the inner circumference of the reverse curved portion.

[0010] Furthermore, the first water blocking ring is made of silicone or rubber.

[0011] As a preferred technical solution of the utility model, a second water blocking ring is provided at the free end of the reverse curved portion.

[0012] As a preferred technical solution of the utility model, the abutting portion is an annular structure with an arc-shaped cross section, extending outward from the outer edge of the end of the mounting end until it abuts against the water tank shell.

[0013] Furthermore, a soft-edge fitting portion is provided at an extended end of the abutting portion, and the soft-edge fitting portion fits the water tank shell.

[0014] As a preferred technical solution of the utility model, a plurality of drainage holes are provided on the abutting portion of the installation end, and the drainage holes are positioned toward the lower end of the water outlet of the pipe joint during installation.

[0015] Furthermore, three drainage holes are provided.

[0016] As a preferred technical solution of the utility model, the water tank shell is provided with an opening for inserting the annular body, and the opening is provided with a water-blocking protrusion extending outward.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] By designing a waterproof structure with a reversed curve, the gap between it and the water tank pipe joint is enlarged, and the installer has a larger operating space when connecting the pipe, which reduces the difficulty of installation and makes the connection more convenient. At the same time, the design of the reversed curve can compensate for the size error of the pipe joint, ensure that an effective seal is formed between the waterproof structure and the pipe joint, avoid water leakage problems, and improve the flexibility and compatibility of installation; by setting multiple water-blocking rings, water is effectively prevented from entering the outer shell from between the pipe joint and the waterproof structure, avoiding the inner tank, copper tube, microchannel and other components from contacting water and then electrochemically corroding, resulting in corrosion and perforation of the inner tank or heat exchanger.

[0019] Several drainage holes are set on the abutment part of the installation end of the waterproof structure. When installed, the drainage holes are located toward the lower end of the water outlet of the pipe joint. When a small amount of water flows into the water tank shell from the gap between the waterproof structure and the shell, it can be smoothly drained from the drainage holes to avoid water accumulation, which helps maintain the sealing performance and prevents the sealing performance from being reduced due to long-term immersion. Even in rainy or humid environments, the drainage holes can help maintain the performance of the product and enhance the adaptability of the product.

[0020] The abutment portion of the waterproof structure is set as an annular structure with an arc-shaped cross-section, extending outward from the through hole until it abuts the water tank shell, that is, it is not directly rigidly connected to the shell. This non-rigid connection design allows the waterproof structure to have better adaptability and elasticity when facing deformation caused by thermal expansion, contraction or other external forces, thereby reducing stress concentration points and helping to extend the service life of the product. In addition, even if the pipe joint and the shell opening are not perfectly aligned, the waterproof structure is designed to cover any off-center part of the shell. This clever processing method ensures that when observed from the outside, the pipe joint is in the center of the shell and the waterproof structure, maintaining the neatness and symmetry of the appearance and improving the overall aesthetics of the product.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 4 As shown, a waterproof water inlet structure 1 is arranged on the pipe joint 3 and is used to seal the gap formed between the pipe joint 3 and the water tank shell 2, including an annular body 10, the annular body 10 has a plug-in end 110 and a mounting end 120, the plug-in end 110 is provided with a reverse curved portion 1100, the plug-in end 110 penetrates into the water tank shell 2 to sleeve the pipe joint 3 and clamps the outer periphery of the pipe joint 3 through the reverse curved portion 1100, the mounting end 120 extends outwardly along the circumferential direction and is provided with a supporting portion 1200, the end of the mounting end sleeve pipe joint 3 and abuts against the water tank shell 2 through the supporting portion 1200.

[0029] By designing the sprue structure 1 with a reverse curved portion 1100, the gap between the sprue structure 1 and the pipe joint 3 is enlarged, and the installer has a larger operating space when connecting the pipe, which reduces the difficulty of installation and makes the connection more convenient. At the same time, the design of the reverse curved portion 1100 can compensate for the size error of the pipe joint 3, ensuring an effective seal between the sprue structure 1 and the pipe joint 3, thereby improving the flexibility and compatibility of installation and avoiding corrosion and perforation of the inner tank or heat exchanger due to water leakage.

[0030] like Figure 1 As shown, in this specific embodiment, two first water-blocking rings 30 made of silicone are provided in the inner circumference of the reverse curved portion 1100 , and a second water-blocking ring 40 is provided at the free end of the reverse curved portion 1100 .

[0031] The multiple water-blocking designs are provided to ensure that water does not penetrate between the inflected portion 1100 and the pipe joint 3 , thereby reducing potential problems caused by the failure of the water-blocking ring seal.

[0032] like Figure 1 As shown, as a preferred embodiment of the present invention, the abutting portion 1200 is an annular structure with an arc-shaped cross section, extending outward from the outer edge of the end of the mounting end 120 until it abuts against the water tank housing 2.

[0033] The arc-shaped abutment portion 1200 can cover and adapt to the structure on the water tank shell 2, and will not directly contact or interfere with the water-blocking protrusion, thereby ensuring the integrity and sealing of the water inlet structure 1, and also helping to enhance the stability and durability of the overall structure; secondly, this structural design effectively guides the water flow to flow down along the outer surface of the abutment portion 1200, reducing the accumulation of water between the abutment portion 1200 and the shell, and reducing the risk of internal components getting damp or damaged.

[0034] Specifically, a soft-edge fitting portion (not shown) is provided at the extended end of the abutting portion 1200 , and the soft-edge fitting portion fits the water tank shell 2 .

[0035] The soft-edge fitting portion can adapt to the slight unevenness of the outer shell surface, so that the sealing cover fits tightly with the outer shell, thereby increasing the fixing stability of the sealing cover and reducing displacement or falling off caused by water flow impact.

[0036] like Figure 4 As shown, in this specific embodiment, three drainage holes 1210 are provided on the abutting portion 1200 of the mounting end 120 , and the drainage holes 1210 are positioned toward the lower end of the water outlet of the pipe joint 3 during installation.

[0037] When a small amount of water flows into the water tank shell 2 from the gap between the water inlet structure 1 and the water tank shell 2, it can be smoothly drained from the drainage hole 1210 to avoid water accumulation, which helps maintain the sealing performance and prevents the sealing performance from being degraded due to long-term immersion. Even in a rainy or humid environment, the drainage hole 1210 can help maintain the performance of the product and enhance the adaptability of the product.

[0038] In this specific embodiment, the water tank housing 2 is provided with an opening (not shown in the figure) for inserting the annular body 10, and a water-blocking protrusion (not shown in the figure) with a height of 3 mm is extended outward from the opening.

[0039] When water flows down from the top, the water flow is guided to flow along the two sides of the water-blocking protrusions to prevent the water from directly entering the water tank housing 2, which helps to improve drainage efficiency and reduce water accumulation.

[0040] Working principle: When a large amount of water flows down from the upper part of the water tank, it will first encounter the mounting end 120 of the nozzle structure 1. The arc-shaped structure of the mounting end 120 guides the water flow to flow down along the outer surface of the soft edge fitting part 1220; due to the impact of the large water flow, a small amount of water may penetrate through the gap between the shell and the nozzle structure 1. The water-blocking protrusions extending outward from the shell make the water flow flow along the two sides of the water-blocking protrusions and be discharged from the drainage holes 1210 of the abutment part 1200, preventing water from entering the shell. Secondly, the plug-in end 110 penetrates into the water tank shell 2 to sleeve the pipe joint 3 and clamps the outer periphery of the pipe joint 3 through the recurved part 1100. Multiple water-blocking rings made of silicone or rubber are set at the plug-in place, which can effectively prevent water from penetrating from the gap between the plug-in end 110 and the pipe joint 3.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
