[0002] The electric water heater system is generally composed of a heating element, a water system and a control system. The heating element converts electrical energy into heat energy through electric current, thereby heating the water. In the water system of the water heater, water is a conductive medium.

In order to prevent this from happening, the water heater is generally equipped with an anti-electric wall in the inner tank.

[0044] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0045] In the description of the embodiments of the present utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0046] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0047] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0048] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model embodiment. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0049] The electric shock wall is usually installed inside the inner tank to prevent the current in the electrical equipment from being transferred into the water through the water pipes to avoid electric shock accidents. If there is no electric shock wall, when there is leakage or failure in the circuit, the current may be transferred into the water through the water pipes, causing the water to be electrified and posing the risk of electric shock.

[0050] The electric shock-proof wall in the related art is generally arranged separately on the inner tank, and the water path of the electric shock-proof wall is distributed on the pipeline, resulting in an increase in the height of the entire water heater.

[0051] The first embodiment of the utility model provides an anti-electric wall water pipe assembly, see Figure 1 and Figure 2 , including a mounting base 100 and an anti-electricity water pipe 210, an anti-electricity wall water channel 110 is formed inside the mounting base 100, a hot water connector 120 and a cold water connector 130 are provided on the mounting base 100, the anti-electricity wall water channel 110 connects the cold water connector 130 and the inner tank 400 of the water heater; a hot water pipe 240 is formed inside the anti-electricity water pipe 210; the hot water pipe 240 is connected to the hot water connector 120.

[0052] It is understandable that, by providing the anti-electricity wall water path 110 on the mounting base 100, the cold water joint 130 is connected to the anti-electricity wall water path 110, thereby ensuring that the cold water passes through the anti-electricity wall water path 110, thereby reducing the intensity of the current and ensuring that it does not affect the user. The mounting base 100 is the supporting part of the anti-electricity wall water pipe assembly, and the anti-electricity wall water path 110 is arranged on the mounting base 100, and there is no need to directly arrange the anti-electricity wall water path 110 on the pipe body, thereby reducing the height of the anti-electricity wall assembly, thereby reducing the height of the entire machine.

[0053] It is understandable that the hot water pipe 240 is arranged inside the anti-electricity water pipe 210, and the cold water joint 130 is connected to the anti-electricity wall waterway 110, which ensures the safety of hot water and cold water electricity use and improves safety; the anti-electricity devices for hot water and cold water are arranged separately and do not interfere with each other, which is convenient for troubleshooting and maintenance. Since hot water generally flows downward from the top of the water heater, the anti-electricity water pipe 210 can be vertically arranged on the mounting seat 100 to facilitate the outflow of hot water; of course, the anti-electricity water pipe 210 can also be arranged at any angle with the mounting seat 100, and the embodiment of the utility model does not specifically limit this.

[0054] The anti-electricity water pipe 210 is generally made of materials with poor electrical conductivity to avoid the risk of electric leakage caused by the conduction of current through the water pipe. For example, the anti-electricity water pipe 210 can be made of non-conductive materials such as plastic (PVC) and polyethylene (PE) to effectively isolate the current, thereby reducing the risk of electric leakage and ensuring the safety of water use. The anti-electricity water pipe 210 can be made of non-conductive materials in whole or in part, as long as the part of the anti-electricity water pipe 210 that contacts water is made of non-conductive materials, and the embodiments of the utility model do not specifically limit this.

[0055] It is understandable that the mounting seat 100, as a supporting part of the anti-electricity wall water pipe assembly, can be used to fix the anti-electricity wall water pipe assembly on the inner tank 400 through the mounting seat 100 to ensure the stability of the anti-electricity wall water pipe assembly; the anti-electricity water pipe 210 can be connected to the mounting seat 100 through the hot water connector 120, which is conducive to fixing the anti-electricity water pipe 210 and preventing the anti-electricity water pipe 210 from collapsing. The anti-electricity wall waterway 110 is arranged inside the mounting seat 100, which is conducive to improving the stability of the anti-electricity waterway; the mounting seat 100 is generally arranged on the side wall of the water heater, and the anti-electricity wall waterway 110 is distributed on the mounting seat 100, which avoids increasing the height of the water heater and is conducive to the flat design of the water heater.

[0056] It is understood that the anti-electricity wall waterway 110 is one of a circular waterway, a circuitous waterway and a spiral waterway. It is understood that the anti-electricity wall waterway 110 disperses the current and increases the resistance by increasing the path length of the current, thereby reducing the intensity of the current. The anti-electricity wall waterway 110 is a circular waterway. For details, please refer to Figure 4The annular waterway is a ring-shaped structure. Such an anti-electric wall waterway 110 has a simple structure and is easy to manufacture. The circuitous waterway increases the path length of the current through multiple curved waterways and hinders the flow of current. The spiral waterway increases the length of the waterway through a spiral arrangement.

[0057] It is understandable that the anti-electricity wall water channel 110 may be located on the same plane or on different planes, thereby increasing the spatial complexity and making the path length of the anti-electricity wall water channel 110 longer.

[0058] It is understood that the effective path length of the anti-electricity wall water channel 110 is 20 mm (millimeter) -25 mm, and the cross-sectional area of ​​the anti-electricity wall water channel 110 is 60 mm 2 (square millimeter)-80mm 2 It should be noted that the effective path of the anti-electricity wall water channel 110 is the cross-sectional area of ​​the pipe through which the cold water passes, which is 60 mm 2 (square millimeter)-80mm 2 (square millimeters) between the length of the waterway section.

[0059] In one embodiment, the effective path length of the anti-electricity wall water channel 110 is 22.5 mm (millimeters), and the cross-sectional area of ​​the anti-electricity wall water channel 110 is 64 mm 2 (square millimeters).

[0060] It should be noted that the utility model does not specifically limit the installation position of the anti-electricity wall water pipe assembly, and the anti-electricity wall water pipe assembly can be installed in any scene where water is needed. For example, the anti-electricity wall water pipe assembly can be set at the interface position of the mixing valve; the anti-electricity wall water pipe assembly can also be set at the water outlet position of the faucet; the anti-electricity wall water pipe assembly can also be set on water-using equipment including water heaters, wall-mounted boilers, faucets, water purification equipment, water dispensers, etc. The anti-electricity wall water pipe assembly can be used as any water delivery pipeline such as the water inlet pipe and water outlet pipe of the water-using equipment. The anti-electricity wall water pipe assembly can be directly connected to the water inlet, water outlet or thermostatic valve of the water-using equipment. The connection method of the anti-electricity wall water pipe assembly and the water-using equipment can be selected and adjusted as needed.

[0061] The embodiment of the utility model takes the arrangement of the anti-electricity wall water pipe assembly on the water heater as an example.

[0062] The mixed water used by users during bathing is a mixture of hot water in the inner tank and cold water from the tap water pipe. Under normal circumstances, there is no current in the tap water in daily life. After being purified by the water plant and insulated by the transmission pipeline, tap water is usually not conductive. However, water pipes or faucets may face problems such as leakage. Or in special circumstances, cold water may carry current. For example, if there is a fault in the booster pump or grounding wire in the home, causing the cold water to contact the charged metal surface, then the cold water may also carry current. Therefore, there is still a risk of leakage during the user's bathing process.

[0063] In the anti-electricity wall water pipe assembly of the embodiment of the utility model, cold water enters the anti-electricity wall water channel 110 after entering from the water inlet of the cold water joint 130. Even if the cold water carries electric current, the anti-electricity wall water channel 110 can reduce the electric current carried by the cold water to a safe range, thereby ensuring that the cold water flowing out from the water outlet 221 of the cold water joint 130 is safe.

[0064] In one embodiment, see Figure 2 The anti-electricity wall water pipe assembly also includes a sleeve 220 , which is sleeved on the outside of the anti-electricity water pipe 210 and forms a cold water pipe 230 between the sleeve 220 and the anti-electricity water pipe 210 , and the anti-electricity wall water channel 110 is connected to the cold water pipe 230 .

[0065] It can be understood that the cold water pipe 230 is formed between the sleeve 220 and the anti-electricity water pipe 210, and the hot water pipe 240 is formed inside the waterproof water pipe. The nested arrangement between the sleeve 220 and the anti-electricity water pipe 210 can reduce the space occupied by the anti-electricity wall water pipe assembly; the sleeve 220 is sleeved on the outside of the anti-electricity water pipe 210, and the sleeve 220 provides a physical barrier for the anti-electricity water pipe 210, effectively protecting the anti-electricity water pipe 210 from damage by the external environment. The sleeve 220 forms a protective layer for the anti-electricity water pipe 210, which prolongs the service life of the anti-electricity water pipe 210. The anti-electricity water pipe 210 can be made entirely of non-conductive materials, and the outer wall of the anti-electricity water pipe 210 is in contact with the water flow in the cold water pipe 230, further improving the anti-electricity effect of the cold water pipe 230.

[0066] In one embodiment, see Figure 1 to Figure 2At least one of the hot water connector 120 and the anti-electricity water pipe 210 is passed through the mounting base 100, and the hot water connector 120 and the anti-electricity water pipe 210 are connected; on the one hand, the fixing of the mounting base 100 to the hot water connector 120 or the anti-electricity water pipe 210 can be strengthened, the stability can be improved, and the connection relationship between the hot water connector 120 and the anti-electricity water pipe 210 can be simpler, which is conducive to later maintenance; on the other hand, it is conducive to the direct connection of the hot water connector 120 and the anti-electricity water pipe 210, without unnecessary excessive pipes in the middle, saving materials, reducing the flow path of hot water, and avoiding heat loss. The hot water connector 120 can be connected to the anti-electricity water pipe 210 through the mounting base 100, or the anti-electricity water pipe 210 can be connected to the hot water connector 120 through the mounting base 100, or the hot water connector 120 and the anti-electricity water pipe 210 can be passed through the mounting base 100 from both sides of the mounting base 100, and then the hot water connector 120 and the anti-electricity water pipe 210 are connected. It should be noted that the anti-electricity water channel should be arranged on the mounting base 100 away from the hot water connector 120 .

[0067] In one embodiment, see Figure 1 , Figure 2 and Figure 4 A connecting pipe 140 is formed inside the mounting seat 100, and the connecting pipe 140 connects the hot water connector 120 and the anti-electricity water pipe 210; the connecting pipe 140, as a connecting component between the hot water connector 120 and the anti-electricity water pipe 210, can guide the hot water flowing through the anti-electricity water pipe 210 to the hot water connector 120; by using the connecting pipe 140, the hot water connector 120 and the waterproof electric pipe can be integrated on the mounting seat 100, and the installation of the cold water pipe 230 and the hot water pipe 240 can be completed through the mounting seat 100, reducing the installation opening on the inner tank 400, improving the pressure bearing capacity of the inner tank 400, and improving the assembly efficiency. The hot water connector 120 and the anti-electricity water pipe 210 are connected by the connecting pipe 140, so that the hot water connector 120 and the anti-electricity water pipe 210 can be connected without coaxial arrangement, which is convenient for adaptive adjustment of the position of the hot water connector 120.

[0068] In the related art, a drain port is required to be provided on the inner liner, and the drain port is used to discharge water or impurities inside the inner liner. Opening a drain port on the inner liner increases the processing steps of the inner liner and affects the pressure bearing capacity of the inner liner.

[0069] In one embodiment, see Figure 4 The mounting base 100 is also provided with a drain connector 150, which is connected to the cold water pipe 230. The drain connector 150 is provided on the mounting base 100, so that it is unnecessary to separately process a drain port on the inner liner 400, which can improve the pressure bearing capacity of the inner liner 400 and improve the assembly efficiency.

[0070] In one embodiment, see Figure 2The mounting base 100 includes a first base body 160 and a second base body 170 that are interlocked with each other, wherein the interlocking can be connected by one or more of a snap-on connection, a magnetic connection, and a screw thread connection.

[0071] In one embodiment, at least one of the first base body 160 and the second base body 170 is provided with a snap-on protrusion (not shown in the figure), and the other is provided with a snap-on groove (not shown in the figure). When the second base body 170 is inserted into or slidably connected to the first base body 160, the snap-on protrusion and the snap-on groove will fit together to form a stable connection, providing a stable installation effect.

[0072] In one embodiment, at least one of the first seat body 160 and the second seat body 170 is provided with a screw mounting seat 100, and the other is provided with a threaded hole (not shown in the figure), which is connected to the threaded hole and connected to the screw mounting seat 100 by screws to form a stable connection.

[0073] The anti-electricity wall water channel 110 can be formed between the first seat body 160 and the second seat body 170, which reduces the difficulty of processing the anti-electricity wall water channel 110; wherein, the anti-electricity wall water channel 110 can be partially formed on the first seat body 160, and the other part is formed on the second seat body 170, and the first seat body 160 and the second seat body 170 are buckled to form a complete anti-electricity wall water channel 110. Of course, the anti-electricity wall water channel 110 can also be a separate pipeline structure installed between the first seat body 160 and the second seat body 170.

[0074] In one embodiment, the first seat body 160 and the anti-electricity water pipe 210 are integrally formed, which can ensure a firm connection between the first seat body 160 and the anti-electricity water pipe 210, avoid weaknesses at the joints, and have higher strength and durability; it can reduce the processes and links in the production process, improve production efficiency, reduce the number of parts, and save production costs and labor costs.

[0075] In one embodiment, see Figure 1 to Figure 2 The second base body 170 is integrally formed with at least one of the cold water connector 130 and the hot water connector 120; this can ensure a firm connection between the cold water connector 130 or the hot water connector 120 and the second base body 170, avoid weaknesses at the joint, and have higher strength and durability; it can reduce the processes and links in the production process, improve production efficiency, reduce the number of parts, and save production costs and labor costs.

[0076] In one embodiment, see Figure 3The side wall of the sleeve 220 is provided with a water outlet 221 connected to the cold water pipe 230. Compared with the end of the sleeve 220, the side wall area of ​​the sleeve 220 is larger, which can increase the water outlet area of ​​the water outlet 221, reduce the risk of poor water inlet caused by blockage of the cold water pipe 230, and improve the stability and safety of the cold water pipe 230.

[0077] In one embodiment, at least two water outlets 221 are provided. Providing multiple water outlets 221 can improve the water outlet efficiency of the water inlet pipe, help disperse the pressure of the water flow, and reduce the risk of blockage of the cold water pipe 230.

[0078] In one embodiment, the water outlets 221 are arranged along the axial direction of the sleeve 220 to ensure that water can flow out from different positions in the axial direction of the sleeve 220, thereby achieving uniform water discharge, avoiding water pressure concentration in a certain section of the sleeve 220, and reducing the risk of the sleeve 220 breaking.

[0079] In one embodiment, the size of the water outlet 221 gradually decreases from the fixed end to the free end of the sleeve 220, so that the water flow gradually increases; it can be understood that the fixed end of the sleeve 220 is fixed on the mounting seat 100, and its free end is vertically upward. From the fixed end to the free end of the sleeve 220, the size of the water outlet 221 gradually decreases, so as to achieve the effect of the water flow moving smoothly upward from the bottom, reducing the fluctuation of the water flow during the water intake process.

[0080] In one embodiment, the water outlets 221 are distributed along the circumferential direction of the sleeve 220, which is beneficial to the uniform distribution of water flow in the circumferential direction of the sleeve 220, increases the coverage area of ​​the water flow, and can also reduce the pressure and flow of a single water outlet 221, reduce the problems caused by uneven local pressure in the pipeline, and improve the reliability and stability of the anti-electric wall water pipe assembly.

[0081] In one embodiment, see Figure 2 The sleeve 220 assembly also includes an end seat 250, which is installed at one end of the sleeve 220 assembly away from the mounting seat 100; the end seat 250 may include at least one of a closing portion 251 and a connecting portion 252, wherein the closing portion 251 is suitable for blocking the end of the sleeve 220 to close the cold water pipe 230, and the connecting portion 252 is suitable for connecting to a water outlet pipe 500, and the water outlet pipe 500 is suitable for exporting hot water in the water heater.

[0082] In one embodiment, the sealing portion 251 may be disposed at one end of the cold water pipe 230 and is adapted to seal the cold water pipe 230 to prevent the cold water in the cold water pipe 230 from flowing out from the end. In a water heater, if the water inlet direction of the anti-electric wall water pipe assembly is vertically upward, the cold water flow may easily interfere with the hot water at the top.

[0083] In one embodiment, the connection part 252 can be embedded in the anti-electricity water pipe 210, and a connection hole for the water outlet pipe 500 to pass through is provided on the connection part 252; the water supply pipe and the connection part 252 can be connected by means of threads or snaps.
