Description

Technical Field

[0001] This utility model belongs to the technical field of electric water heater components, and in particular relates to an electric water heater outlet pipe with good sealing effect. Background Technology

[0002] An electric water heater is a household or commercial appliance that uses electricity to heat cold water in a storage container and outputs hot water. Its core components include the inner tank, heating element, temperature control system, and inlet and outlet water pipes. The outlet pipe, as a key connecting component, is responsible for transporting the heated hot water from the inner tank to the user. Traditional outlet pipes are typically made of metal or plastic and connect to the water heater body via a threaded interface, relying on sealing gaskets or Teflon tape to prevent leaks.

[0003] Traditional water outlet pipes generally use a threaded connection with a single sealing gasket. Long-term exposure to hot water, temperature fluctuations, and vibrations can easily lead to the following problems: repeated thermal stress increases the gap between the metal threads, causing the sealing surface to detach; scale buildup in hard water areas wears down the sealing surface, increasing the risk of leakage; and a single sealing structure is insufficient to compensate for pipe dimensional tolerances or deformations. Therefore, we provide a water outlet pipe for electric water heaters with a high sealing performance to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an electric water heater outlet pipe with good sealing effect. Through the cooperation of the installation mechanism and the sealing mechanism, it solves the problems of existing outlet pipes, such as repeated thermal stress causing the metal thread gap to increase, the sealing surface to detach, and the difficulty of a single sealing structure to compensate for pipe size tolerances or deformation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a water outlet pipe for an electric water heater with good sealing performance. It includes an electric water heater body, an anti-electric shock wall connected to the bottom of the body, an installation mechanism connected to the bottom of the anti-electric shock wall, a sealing mechanism inside the installation mechanism, and a water outlet pipe inside the sealing mechanism. The installation mechanism includes an installation ring connected to the bottom of the anti-electric shock wall, an installation plate fixedly connected to the bottom of the installation ring, and a fixing plate fixedly connected to the bottom of the installation plate by bolts. The sealing mechanism includes a sealing block disposed inside the installation ring, a sealing ring fixedly connected inside the installation ring, a pressing plate contacting the top of the sealing block, and a sealing insert plate fixedly connected to the bottom of the pressing plate.

[0007] The present invention is further provided that a sealing gasket is provided between the mounting plate and the fixing plate, and the mounting plate, the fixing plate and the sealing gasket are all provided with mounting through holes adapted to the bolts.

[0008] The present invention is further configured such that there are two sealing rings, and the surface of the sealing block is provided with a sealing groove that is adapted to the sealing rings.

[0009] The present invention is further configured such that a limiting plate is fixedly connected to the surface of the water outlet pipe, and a limiting groove adapted to the limiting plate is provided at the bottom of the sealing block.

[0010] The present invention is further configured such that both the sealing block and the fixing plate have through holes adapted to the water outlet pipe, and the top of the sealing block and the bottom of the squeezing plate are both designed to be inclined.

[0011] The present invention is further configured such that a sealing slot adapted to the sealing insert is provided on the top of the sealing block, the length of the sealing insert is greater than the depth of the sealing slot, the material of the sealing insert is rubber, and the shape of the sealing insert is annular.

[0012] The present invention has the following beneficial effects.

[0013] 1. This utility model forms the first radial sealing barrier by embedding double sealing rings into the sealing groove. Combined with the interference fit between the rubber sealing plate and the sealing slot, a second dynamic seal is achieved through wrinkle compensation. The sealing gasket between the mounting plate and the fixing plate constitutes the third planar sealing defense. This triple sealing structure works synergistically to effectively address metal deformation caused by thermal stress, scale wear, and pipe tolerance deviations. Through radial pressure compensation, axial preload retention, and elastic material deformation, it significantly improves sealing reliability under complex operating conditions and reduces the risk of leakage during long-term use of the water heater.

[0014] 2. This utility model employs a combination design of an elastic rubber sealing plate and an inclined contact surface. During bolt tightening, the inclined surface of the compression plate pushes the sealing block to generate axial pressure, ensuring a tight engagement between the sealing ring and the sealing groove. The wrinkling deformation of the sealing plate due to length deviations adapts to the microscopic unevenness and dimensional tolerances of the water outlet pipe surface. Combined with the precise positioning of the limiting plate and limiting groove, it ensures the centered assembly of the sealing element. This structure breaks through the traditional single sealing mode, achieving adaptive contact of the sealing surface through a multi-dimensional compensation mechanism of elastic body deformation, mechanical preload, and geometric constraints, significantly extending the service life of the sealing mechanism.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1 Please see Figures 1-4 This utility model is a water outlet pipe for an electric water heater with good sealing effect, including an electric water heater body 1, an anti-electric wall 2 connected to the bottom of the electric water heater body 1, an installation mechanism 3 connected to the bottom of the anti-electric wall 2, a sealing mechanism 4 inside the installation mechanism 3, and a water outlet pipe 5 inside the sealing mechanism 4. The installation mechanism 3 includes an installation ring 301 connected to the bottom of the anti-electric wall 2, an installation plate 302 fixedly connected to the bottom of the installation ring 301, and a fixing plate 303 fixedly connected to the bottom of the installation plate 302 by bolts. The sealing mechanism 4 includes a sealing block 401 disposed inside the installation ring 301, a sealing ring 402 fixedly connected inside the installation ring 301, a pressing plate 403 contacting the top of the sealing block 401, and a sealing insert plate 404 fixedly connected to the bottom of the pressing plate 403.

[0024] Specifically: Through the installation mechanism 3, a sealing gasket 6 is set between the installation plate 302 and the fixing plate 303 to prevent water leakage at the connection surface and provide an installation base for the sealing mechanism 4. Through the sealing mechanism 4, two sealing rings 402 are embedded in the sealing groove 7 of the sealing block 401 to form the first sealing barrier and prevent water from seeping laterally. The length of the sealing insert plate 404 exceeds the depth of the sealing slot 10. During installation, it is squeezed and wrinkled to compensate for dimensional tolerances and fit the surface of the water outlet pipe 5 to form a dynamic seal. The top of the sealing block 401 and the bottom of the extrusion plate 403 are both inclined. When the bolts are tightened, axial pressure is generated to enhance the fit of the sealing surface. The installation mechanism 3 provides rigid support to ensure accurate alignment of the sealing element. The sealing mechanism 4 uses a multi-stage sealing design to cope with complex working conditions and ultimately achieve reliable leak prevention. The combination of the two solves the problem of the traditional electric water heater's water outlet pipe 5 having a single sealing structure and being prone to aging and leakage.

[0025] Example 2 Please see Figures 1-4 Based on Embodiment 1, a sealing gasket 6 is provided between the mounting plate 302 and the fixing plate 303. The mounting plate 302, the fixing plate 303 and the sealing gasket 6 are all provided with mounting through holes adapted to the bolts. There are two sealing rings 402. The surface of the sealing block 401 is provided with a sealing groove 7 adapted to the sealing ring 402. The surface of the water outlet pipe 5 is fixedly connected to a limiting plate 8. The bottom of the sealing block 401 is provided with a limiting groove 9 adapted to the limiting plate 8. The interior of the sealing block 401 and the fixing plate 303 are both provided with through holes adapted to the water outlet pipe 5. The top of the sealing block 401 and the bottom of the extrusion plate 403 are both designed with inclination. The top of the sealing block 401 is provided with a sealing slot 10 adapted to the sealing insert plate 404. The length of the sealing insert plate 404 is greater than the depth of the sealing slot 10. The material of the sealing insert plate 404 is rubber and the shape of the sealing insert plate 404 is circular.

[0026] Specifically: the sealing gasket 6 improves the sealing effect between the mounting plate 302 and the fixing plate 303; the through hole allows bolts to pass through the mounting plate 302 and the fixing plate 303 to complete the installation of the fixing plate 303; the sealing groove 7 allows the sealing ring 402 to enter the sealing groove 7 to prevent water leakage; the limiting plate 8 and the limiting groove 9 limit the insertion depth of the water outlet pipe 5 when it is inserted; the through hole allows the water outlet pipe 5 to pass through to the top of the sealing block 401; and the longer sealing insert plate 404 causes the pressing plate 403 to continuously press during installation, resulting in wrinkles on the sealing insert plate 404. These wrinkles contact the water outlet pipe 5, compensating for dimensional errors and further improving the sealing effect.

[0027] The working principle of this utility model is as follows: the water outlet pipe 5 is passed through the through hole of the fixing plate 303 and the sealing block 401 in sequence, so that the limiting plate 8 enters the limiting groove 9. Then, the extrusion plate 403 is placed on the top of the sealing block 401, the sealing insert plate 404 is inserted downward into the sealing slot 10 of the sealing block 401, the sealing block 401 is inserted into the inner cavity of the mounting ring 301, the bolt is passed through the mounting through hole and the bolt is continuously tightened.

[0028] During the bolt tightening process, the fixing plate 303 drives the sealing block 401 to move upward continuously. During the movement, the sealing block 401 continues to move upward. At this time, the sealing ring 402 enters the sealing groove 7 of the sealing block 401, completing the first sealing process. When the top of the extrusion plate 403 contacts the top of the inner cavity of the mounting ring 301, it continuously extrudes the sealing insert plate 404 to move into the sealing slot 10. The depth of the sealing slot 10 is less than the length of the sealing insert plate 404, so the sealing insert plate 404 is squeezed and wrinkles are generated to compensate for the dimensional error. At this time, the extrusion plate 403 and the sealing insert plate 404 form a second seal. After the bolt is tightened, the sealing gasket 6 forms a third sealing process.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
