Description

Technical Field

[0001] This utility model relates to the field of floor heating auxiliary equipment technology, and in particular to a wiring device for electric floor heating. Background Technology

[0002] In northern my country, heating is mostly provided by centralized coal-fired boilers. The heat dissipation method is primarily underfloor heating pipes, in which water flows. The boiler heats the water, which then dissipates heat within the pipes. However, a drawback of centralized heating is the uncontrollable water temperature for each household. Because each household has different house layouts and locations, the temperature varies between homes. Furthermore, each household has different temperature preferences, meaning centralized heating cannot meet the needs of every resident for adequate heating.

[0003] Currently, electric or gas-fired wall-mounted boilers are being used as alternatives to centralized heating. This type of heating system involves disconnecting the centralized heating system from the household and connecting the electric or gas-fired boiler to the household, creating a small-scale water circulation system to heat the water in the underfloor heating pipes. However, the equipment has a relatively short lifespan, generally around 5-8 years. Furthermore, electric underfloor heating systems have slow heat conduction, high energy consumption, and high heating costs. Even with the underfloor heating pipes needing to be cleaned every 3 years, the heating effect will still decline year by year, and the equipment failure rate is relatively high, affecting the normal lives of users.

[0004] The solution is to insert heating wires into the water pipes, and then heat the water in the pipes by energizing the wires. However, the existing water pipes are already filled with water, and the challenge of the renovation is how to run the wires through the water pipes that cover the entire house. Therefore, in the process of converting from centralized heating or electric or gas boiler heating to electric underfloor heating, there is an urgent need for a wiring device for electric underfloor heating. Summary of the Invention

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a wiring device for electric heating floor heating, which solves the technical problem of difficulty in threading wires into water heating pipes that cover the entire house.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include: This utility model embodiment provides a wiring device for electric underfloor heating, including a housing, a water pump disposed inside the housing for transporting liquid, and a water tank disposed on the top surface of the housing. The water tank has a first wiring hole, which is connected to a first wiring conduit. The free end of the first wiring conduit is connected to the inlet pipe of the underfloor heating pipe. The outlet pipe of the underfloor heating pipe is connected to one end of a second wiring conduit. The other end of the second wiring conduit is connected to the first inlet / outlet of the water pump. The second inlet / outlet of the water pump is connected to the water tank through a return pipe. The water pump can rotate in both directions to deliver and draw the wire.

[0007] Optionally, the housing includes a main shell with an open front side, a cover plate detachably connected to the open front side and used to cover the open front side, and the main shell includes a rear side wall and a first side wall, a second side wall, a third side wall and a fourth side wall surrounding one edge of the rear side wall. The fourth side wall has a groove for placing the water tank, and the water tank extends downward through the groove to form a chamber.

[0008] Optionally, the first wiring hole is located below the fourth sidewall, and the first wiring tube includes a first horizontal tube connected to the first wiring hole, a vertical tube connected perpendicular to the first horizontal tube, and a second horizontal tube connected to the vertical tube. The second horizontal tube and the first horizontal tube extend in opposite directions relative to the vertical tube.

[0009] Optionally, an arc-shaped structure is provided between the second conduit and the water pump.

[0010] Optionally, it also includes a winding mechanism, which is disposed on the fourth side wall of the housing, and multiple turns of heating wire are wound on the winding mechanism. The free end of the heating wire can extend into the first wiring hole. Driven by the forward rotation of the water pump, the heating wire flows in the first direction with the water in the water tank. The heating wire passes through the first horizontal pipe, the vertical pipe, the second horizontal pipe, the inlet of the floor heating pipe, the outlet of the floor heating pipe, and the arc-shaped part of the second wiring pipe in sequence to complete the wire delivery process. Driven by the reverse rotation of the water pump, the heating wire flows in a second direction opposite to the first direction along with the water in the tank. The heating wire sequentially passes through the second conduit, the outlet of the underfloor heating pipe, the inlet of the underfloor heating pipe, the second horizontal pipe, the vertical pipe, the first horizontal pipe, and the first conduit hole to complete the wire pulling process.

[0011] Optionally, an electric button capable of driving the water pump switch is provided on the fourth side wall of the housing, and a power source is provided in the inner cavity of the housing, which is connected to the water pump through the electric button.

[0012] The beneficial effects of this utility model are: This utility model provides a wiring device for electric underfloor heating. By setting up a simple wiring device, it can achieve effective wiring in the renovation of electric underfloor heating, and also make the space structure of the box compact. Moreover, the heating wire is transported through the first wiring hole in the water tank and transported by the water pump. At the same time, the water tank stores water to provide a water source. As the water pump transports water, it sends the heating wire into the underfloor heating pipe, effectively solving the technical problem of difficulty in threading the wire into the water heating pipes that cover the whole house.

[0013] In addition, the water tanks are nested within the box body, making the overall space structure compact during transportation or packaging, thus making the entire wiring device easy to handle and store during transportation. Attached Figure Description

[0016] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper" and "lower" are used interchangeably with... Figure 1 The orientation is used as a reference.

[0017] Reference Figures 1-2As shown, a wiring device for electric underfloor heating includes a housing 1, a water pump 2 disposed inside the housing 1 for conveying liquid, and a water tank 4 disposed on the top surface of the housing 1. The water tank 4 has a first wiring hole 41, which is connected to a first wiring pipe 42. The free end of the first wiring pipe 42 is connected to the inlet pipe of the underfloor heating pipe. The outlet pipe of the underfloor heating pipe is connected to one end of a second wiring pipe 43. The other end of the second wiring pipe 43 is connected to the first inlet / outlet 21 of the water pump 2. The second inlet / outlet 22 of the water pump 2 is connected to the water tank 4 through a return pipe 23. The water pump 2 can rotate in both directions to deliver and draw the wire.

[0018] This embodiment provides a wiring device for electric underfloor heating. By setting up a simple wiring device, it is possible to achieve effective wiring in the modification of electric underfloor heating, and also to make the spatial structure of the box 1 compact. Moreover, the heating wire is transported through the first wiring hole in the water tank and transported by the water pump. At the same time, the water tank stores water to provide a water source. As the water pump transports water, it sends the heating wire into the underfloor heating pipe, effectively solving the technical problem of difficulty in threading the wire into the water heating pipes that cover the whole house.

[0019] In addition, the water tanks 4 are all nested within the box body 1, making the overall space structure compact during transportation or packaging, thus making the entire threading device easy to handle and store during transportation.

[0020] Furthermore, the housing 1 includes a main outer shell 11 with an open front side, a cover plate 12 detachably connected to the open side of the main outer shell 11 for sealing the open side, and the main outer shell 11 includes a rear side wall 111 and a first side wall 112, a second side wall 113, a third side wall 114, and a fourth side wall 115 surrounding one edge of the rear side wall 111. The fourth side wall 115 has a groove 116 for placing the water tank 4, and the water tank 4 extends downward through the groove 116 to form a chamber. The water tank 4 has a large internal space, high operability, and is easy to install and disassemble.

[0021] It should be noted that the cover plate 12 is a transparent window. This is to facilitate observation of the water pump 2 and the location of the underfloor heating lines inside the housing 1.

[0022] Furthermore, the first wiring hole 41 is located below the fourth side wall 115, and the first wiring conduit 42 includes a first horizontal pipe 421 connected to the first wiring hole 41, a vertical pipe 422 connected perpendicular to the first horizontal pipe 421, and a second horizontal pipe 423 connected to the vertical pipe 422. The second horizontal pipe 423 extends in the opposite direction to the first horizontal pipe 421 relative to the vertical pipe 422. The structural arrangement of the first wiring conduit 42 facilitates the introduction of the heating wire into the underfloor heating pipe.

[0023] Furthermore, an arc-shaped structure 431 is provided between the second conduit 43 and the water pump 2. The purpose of the arc-shaped structure 431 is to prevent the heating wire from entering the water pump 2 by setting up a blocking structure at the end of the second conduit 43, thereby ensuring the operation of the water pump 2.

[0024] Furthermore, it also includes a winding mechanism 7, which is disposed on the fourth side wall 115 of the housing 1, and multiple turns of heating wire are wound on the winding mechanism 7. The free end of the heating wire can extend into the first wiring hole 41. Driven by the forward rotation of the water pump 2, the heating wire flows in the first direction along with the water in the water tank 4. The heating wire passes through the first horizontal pipe 421, the vertical pipe 422, the second horizontal pipe 423, the inlet of the floor heating pipe, the outlet of the floor heating pipe, and the arc-shaped structure 431 of the second wiring pipe 43 in sequence to complete the wire delivery process.

[0025] Driven by the reverse rotation of water pump 2, the heating wire flows in a second direction opposite to the first direction along with the water in water tank 4. The heating wire sequentially passes through the second conduit 43, the outlet of the underfloor heating pipe, the inlet of the underfloor heating pipe, the second horizontal pipe 423, the vertical pipe 422, the first horizontal pipe 421, and the first conduit hole 41 to complete the wire drawing process. It should be noted that the heating wire on the winding mechanism 7 is wound multiple times.

[0026] In this embodiment, the water pump 2 is positioned between the second conduit 43 and the return pipe 23. The water pump 2, by rotating forward, drives the heating wire through the first conduit hole 41, propelling the water in the water tank 4. The heating wire is then pumped along with the water flow to the first horizontal pipe 421, the vertical pipe 422, the second horizontal pipe 423, the inlet of the underfloor heating pipe, the outlet of the underfloor heating pipe, and the arc-shaped structure 431 of the second conduit 43 to complete the wire delivery. Simultaneously, the heating wire is manually inserted through the first conduit hole 41. The water flows under negative pressure, thus driving the heating wire through the conduit. This negative pressure is generated by the water pressure from the pump. If it is necessary to remove the heating wire, the water pump 2 is reversed to pull the heating wire back.

[0027] Furthermore, an electric button capable of driving the water pump switch is installed on the top of housing 1, and a power supply is installed inside housing 1, which is connected to the water pump via the electric button. The one-button start is simple to operate and easy to wire. The electric buttons controlling water pump 2 are all existing technologies and will not be described in detail here.

[0028] Furthermore, a humidity sensor is installed inside the enclosure 1, and the humidity sensor transmits a signal to the controller inside the enclosure 1. The controller can then send the signal to a buzzer for alarm activation. The enclosure 1 integrates a control panel, on which the controller is located. The control panel also includes a power supply. The humidity sensor can detect whether the water pump 2 inside the enclosure 1 is leaking and promptly alerts users to perform maintenance. It should be noted that the temperature sensor, controller, and control panel are all existing technologies and will not be described in detail here.
