Description

Technical Field

[0001] This utility model belongs to the technical field of water heater equipment, and in particular relates to an integrated quick-installation electronic anode structure for water heaters. Background Technology

[0002] Current technologies generally use magnesium rods or electron anodes to prevent corrosion of the water heater tank. The former requires a separate hole to be drilled in the tank to install the magnesium rod (as shown in the attached image). Figure 1 As shown), the magnesium rod, as a sacrificial anode, needs to be inspected and replaced regularly, and after losing electrons, it produces a large amount of magnesium compounds, polluting the water. The latter has a longer service life and is generally installed on a flange with an integrated heating element (as shown in the attached image). Figure 2 As shown in the figure, this installation method is not only inconvenient for later maintenance (the internal maintenance cover of the outer shell needs to be removed to expose the flange on the inner tank), but also places higher demands on the sealing performance of the connection between the electronic anode and the flange. After the two are installed, a sealing test is required to prevent water leakage at the mounting hole of the electronic anode. In addition, attention should be paid to the insulation of the two circuits of the electronic anode and the heating tube. The overall installation process is complicated. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an integrated quick-installation electronic anode structure for water heaters. This utility model improves upon the existing electronic anode technology, resulting in a simple overall structure that is easy to manufacture. Furthermore, it allows for quick installation and removal at the water inlet of the water heater without the need for specialized personnel.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] An integrated quick-installation electronic anode structure for a water heater includes an electronic anode rod and an installation tube assembled with the water inlet of the water heater. The inner wall of the installation tube is equipped with a base for installing the electronic anode rod, and the base has a through hole for connecting the inner tank of the water heater and the water inlet.

[0006] The wires of the electronic anode rod are embedded in the base and extend to the outside.

[0007] Preferably, one end of the installation pipe is provided with a threaded section for screwing a pre-set thread at the water inlet of the water heater, and the other end is connected to an external water source.

[0008] Preferably, the base is also equipped with a water pipe that covers the outside of the electron anode rod, and a water outlet is opened on the end of the water pipe away from the base;

[0009] The water outlet, through hole, and water pipe form a water passage connecting the inner tank of the water heater and the installation pipe.

[0010] Preferably, the end of the water pipe away from the base is also equipped with a water-blocking cap for deflecting the water flow direction from the outlet.

[0011] Preferably, the water pipe and the base are screwed together by a preset threaded section.

[0012] Preferably, the mounting tube is injection molded and fixedly connected to the base, and the mounting tube is also provided with a power supply connector that is electrically connected to the wire of the electronic anode rod.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1) Easier installation on water heaters: This utility model directly installs the electronic anode on the water inlet, exposing the installation tube that carries the electronic anode to the outside. At the same time, the installation tube is screwed into the pre-set thread of the water inlet of the water heater and the joint of the external water pipe through the pre-set threaded section. Therefore, the installation and disassembly of the installation tube is very convenient. The airtightness requirement can be guaranteed by setting a waterproof gasket at the installation point of the installation tube. The overall operation requires less professional expertise.

[0015] 2) This utility model has a simple structure and low production difficulty: the base serves as the main body for supporting the electronic anode rod (the wires of the electronic anode rod are embedded in the base). After the water pipe is screwed, the installation pipe is injection molded on the outside of the base (the wires also pass through the installation pipe). The overall operation is simple. Moreover, the water pipe, base, electronic anode rod and installation pipe can all be produced and customized in a standardized manner, resulting in low production cost and high assembly efficiency. Furthermore, the wires are completely covered by the base and installation pipe to achieve insulation.

[0016] 3) The structural improvements of this utility model are reasonable:

[0017] This utility model not only carries the electronic anode, but also carries the water pipe connecting the inner tank and the external water source. The water pipe brings external cold water into the inner tank through the installation pipe-through hole-water pipe-outlet hole. At the same time, the water baffle cap allows the water discharged from the outlet hole to flow towards the bottom of the inner tank, rather than rushing directly into the inner tank and causing turbulence to the hot water on the upper layer of the inner tank, thereby ensuring the outlet water temperature.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] First, there are existing technologies: such as Figure 1 As shown, a magnesium rod 11 is installed through a separate opening on the inner liner 1; as Figure 2 As shown, the electronic anode 12 is mounted on a flange 13 with an integrated heating tube, the flange 13 being mounted on the inner liner and covered by a maintenance cover 14;

[0025] This embodiment is as follows: Figure 3-5 As shown:

[0026] An integrated quick-installation electronic anode structure for a water heater includes a base 6 for mounting an electronic anode rod 7. The base 6 has a through hole 62. A water pipe 3, which covers the outside of the electronic anode rod 7, is screwed onto the base 6 through a preset assembly thread section 61. The end of the water pipe 3 away from the base 6 is assembled with a water baffle cap 4, and a water outlet 31 is provided on the pipe body at this end of the water pipe 3. The water baffle cap 4 deflects and guides the water outlet direction of the water outlet 31.

[0027] The base 6 is also injection molded with an installation tube 2. The base 6 and the installation tube 2 are embedded with wires 71 of electronic anode rod 7, and the free end of the wire extends to the outside and is electrically connected to the power supply connector 5. One end of the installation tube 2 is provided with a first iron threaded section 22 for screwing the pre-threaded water inlet of the water heater, and the other end is provided with a second iron threaded section 21 and screwed to the cold water pipe connector connected to the water source.

[0028] The water outlet 31, through hole 62, and water pipe 3 form a water passage connecting the inner tank 1 of the water heater and the installation pipe 2.

[0029] The assembly process of the electronic anode structure described in this embodiment is as follows:

[0030] The base 6 and the water pipe 3 are assembled using the assembly thread section 61, and then the mounting pipe 2 is injection molded on the outside of the base 6 (this process ensures that the wire 71 connector of the electronic anode is exposed to the outer wall of the mounting pipe 2).

[0031] After the installation pipe 2 is formed, the water pipe 3 and the water cap 4 can be inserted and matched.

[0032] The installation process of the electronic anode structure and water heater described in this embodiment is as follows:

[0033] Insert the end with the water baffle cap 4 into the inner tank 1 through the water inlet 16. Then screw the first iron threaded section 22 of the installation pipe 2 into the threaded section preset on the inner wall of the water inlet 16. Next, screw the second iron threaded section 21 of the installation pipe 2 into the connector of the cold water pipe. Finally, connect the power supply connector 5 to the wire and the power board 15 of the water heater.

[0034] During use, the cold water pipe brings outside cold water into the inner tank 1 through the installation pipe 2-through hole 62-water pipe 3-outlet hole 31. At the same time, the water baffle cap 4 is set so that the water discharged from the outlet hole flows towards the bottom of the inner tank 1, instead of rushing into the inner tank directly and causing turbulence to the hot water on the upper part of the inner tank, thus ensuring the outlet water temperature.
