Water inlet pipe of high-efficient cold and hot layered anti-electric wall

Abstract

This utility model discloses a high-efficiency hot and cold water stratification anti-electric shock wall water inlet pipe, relating to the field of hardware equipment technology. The utility model includes a connecting pipe, the top of which is connected to a water supply pipe, and an isolation pipe fixedly connected to the surface of the water supply pipe; a buffer assembly is installed inside the isolation pipe. This utility model significantly improves the hot and cold water stratification effect by setting up four sets of twisted circulation pipes arranged circumferentially around the water supply pipe, and buffer pipes perpendicularly aligned with the circulation pipes. When cold water enters the circulation pipe through the water supply pipe, the twisted design extends the water flow path, reduces water pressure, and slows down the flow rate. The buffer pipes cooperate with the buffer tank, causing the water flow discharged from the circulation pipe and the buffer pipe to collide vertically within the buffer tank, offsetting high-pressure impacts and reducing eddy current generation. This structure effectively avoids the problem of hot and cold water mixing caused by cold water directly entering the hot water layer, ensuring stable hot and cold water stratification in the water storage tank and improving the continuity and comfort of hot water output.

Description

Technical Field

[0001] This utility model belongs to the field of hardware equipment technology, and in particular relates to a high-efficiency cold and heat stratification anti-electric shock wall water inlet pipe. Background Technology

[0002] The anti-electric shock inlet pipe is a special safety protection pipe fitting, mainly used in water-related electrical appliances such as electric water heaters. Its design principle involves constructing a "firewall-like" structure inside the inlet pipe. When an appliance leaks electricity, the water inside the inlet pipe extends the water resistance, thereby reducing the current passing through the human body and ensuring the user's safety. It is generally made of high-quality insulating materials, possessing excellent corrosion resistance and sealing properties. It is easy to install and compatible with various sizes of water pipes and water-related appliances, making it an important component for improving the safety of household electricity and water use.

[0003] Current anti-electric shock wall water inlet pipes typically utilize extended water delivery channels to weaken the impact force of the water flow and prevent cold water from entering the hot water layer when delivering water into the cylinder. However, the impact force of the water flow results in minimal pressure change before and after entering the pipe, causing cold water entering the cylinder to still generate eddies, thus disturbing the hot water layer and leading to unstable hot and cold water output. To address these issues, we provide a highly efficient hot and cold water stratification anti-electric shock wall water inlet pipe. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency hot and cold water stratification anti-electric shock wall water inlet pipe. By setting up a buffer component, it solves the problem in the prior art that when cold water rushes into the cylinder, it will generate eddies, which will cause the hot water layer to be disturbed and the output of hot and cold water is not stable.

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

[0006] This utility model is a high-efficiency cold and hot stratification anti-electric shock wall water inlet pipe, including a connecting pipe, a water supply pipe connected to the top of the connecting pipe, and an isolation pipe fixedly connected to the surface of the water supply pipe; a buffer assembly is provided inside the isolation pipe, the buffer assembly includes a circulation pipe connected to one end of the water supply pipe, a buffer groove opened on the surface of the isolation pipe, and a buffer pipe connected to one end of the circulation pipe.

[0007] The present invention is further configured such that the other end of the circulation pipe extends through to the outside of the buffer groove, and the other end of the buffer pipe extends through to the outside of the buffer groove.

[0008] The present invention is further configured such that an end cap is installed on the top of the water supply pipe, and the circulation pipe and the buffer pipe are kept vertically aligned.

[0009] The present invention is further configured such that an outer tube is installed at the bottom of the connecting pipe, and an installation groove is provided at the top of the connecting pipe.

[0010] The present invention is further configured such that the outer tube has an external thread inside, and the mounting groove has an internal thread inside.

[0011] The present invention is further configured such that a sealing gasket is provided inside the mounting groove, and a sealing ring is fitted on the surface of the outer tube.

[0012] The present invention is further configured such that the circulation pipe is a twisted design, and there are four sets of circulation pipes arranged in a circle around the water supply pipe as the axis.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model significantly improves the stratification effect of hot and cold water by setting up four sets of twisted circulation pipes arranged circumferentially around the water supply pipe as the axis, and buffer pipes perpendicularly aligned with the circulation pipes. When cold water enters the circulation pipe through the water supply pipe, the twisted design extends the water flow path, reduces water pressure and slows down the flow rate. The buffer pipes and buffer tanks work together to make the water flow discharged from the circulation pipes and buffer pipes collide vertically in the buffer tank, offsetting the high pressure impact and reducing the generation of eddies. This structure effectively avoids the problem of hot and cold water mixing caused by cold water directly rushing into the hot water layer, ensuring the stability of hot and cold water stratification in the water storage tank and improving the continuity and comfort of hot water output.

[0015] 2. This utility model significantly enhances the stability and safety of pipe connections through the threaded fit design of the connecting pipe and the outer pipe, combined with the double sealing structure of the sealing gasket and the sealing ring. During installation, rotating the connecting pipe allows for a tight connection with the external thread of the water storage cylinder. The sealing gasket fills the gaps to prevent water leakage, and the sealing ring on the surface of the outer pipe further blocks external moisture intrusion, avoiding the risk of electric leakage. In addition, the isolation pipe's protective design for the circulation pipe extends the service life of the equipment and significantly improves the reliability of the anti-electric shock wall water inlet pipe.

[0016] 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

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-4 This utility model is a high-efficiency cold and hot stratification anti-electric wall water inlet pipe, including a connecting pipe 1, a water supply pipe 2 connected to the top of the connecting pipe 1, and an isolation pipe 3 fixedly connected to the surface of the water supply pipe 2; a buffer assembly is provided inside the isolation pipe 3, the buffer assembly includes a circulation pipe 4 connected to one end of the water supply pipe 2, a buffer groove 5 opened on the surface of the isolation pipe 3, and a buffer pipe 6 connected to one end of the circulation pipe 4.

[0026] Further expansion: The top of the connecting pipe 1 is provided with an installation groove 9, and the inside of the installation groove 9 is provided with an external thread 10. When connected to an external water storage tank, the connecting pipe 1 can be rotated to connect with the external threaded pipe at the bottom of the water storage tank. The sealing gasket 12 is used to increase the sealing of the connection with the water storage tank. The water supply direction is from the connecting pipe 1 into the water supply pipe 2, and then discharged through the circulation pipe 4. The isolation pipe 3 is installed on the surface of the water supply pipe 2 to shield and protect the circulation pipe 4, and at the same time, it plays an isolation role.

[0027] Example 2

[0028] Please see Figures 1-4 Based on Embodiment 1, the other end of the circulation pipe 4 extends to the outside of the buffer tank 5, and the other end of the buffer pipe 6 extends to the outside of the buffer tank 5. An end cap 7 is installed on the top of the water supply pipe 2. The circulation pipe 4 and the buffer pipe 6 are vertically aligned. An outer pipe 8 is installed at the bottom of the connecting pipe 1. An installation groove 9 is opened at the top of the connecting pipe 1. An external thread 10 is opened inside the outer pipe 8. An internal thread 11 is opened inside the installation groove 9. A sealing gasket 12 is provided inside the installation groove 9. A sealing ring 13 is fitted on the surface of the outer pipe 8. The circulation pipe 4 has a twisted design, and there are four sets of circulation pipes 4 arranged circumferentially around the water supply pipe 2.

[0029] Further expansion: There are four sets of circulation pipes 4, which are arranged in a circle around the water supply pipe 2. When water flows into the circulation pipe 4 through the water supply pipe 2, the circulation path of the water flow can be increased to reduce water pressure. The buffer pipe 6 is connected to the circulation pipe 4. The water flow entering the circulation pipe 4 can also be discharged through the buffer pipe 6 to disperse the flow direction of the water flow. The outer pipe 8 has an external thread 10 for connecting with the external anti-electric wall and the water inlet pipe. The sealing gasket 12 and the sealing ring 13 are both made of rubber, which can improve the sealing performance when the connecting pipe 1 is connected.

[0030] The working principle of this utility model is as follows: When water enters through the connecting pipe 1, it enters the circulation pipe 4 through the water supply pipe 2. The circulation pipe 4 is designed with a bend to increase the circulation path of the water flow and reduce the water pressure of the cold water entering. The water flows out through the circulation pipe 4 and the buffer pipe 6, and the cold water is fed into the water storage tank. When the water flows out through the circulation pipe 4 and the buffer pipe 6, the water flow discharged from the circulation pipe 4 is discharged downward through the upper end face of the buffer tank 5, and the water flow discharged from the buffer pipe 6 is discharged through the lower end face of the buffer tank 5. The upper and lower end faces of the buffer tank 5 are designed symmetrically, so the discharged water flows can impact each other, offset the high pressure generated by the water jet, reduce the eddy current effect generated by the cold water entering the water storage pipe, avoid excessive interference to the hot water, and improve the effect of hot and cold stratification.

[0031] 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.
