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.

[0041] Combination Figures 1 to 4 As shown, the water circuit assembly of the water heater according to the embodiment of the first aspect of the utility model includes an anti-electricity water pipe 34, which is connected to the water heater body 10, and the anti-electricity water pipe 34 includes at least one of the water inlet pipe 31 and the water outlet pipe 32, and the anti-electricity water pipe 34 includes a central pipe 341 and a plurality of sleeves 342 sleeved on the central pipe 341, and the central pipe 341 and the sleeves 342 are connected in sequence to form a circuitous water circuit in the central pipe 341 and the sleeves 342, and one of the central pipe 341 and the outermost sleeve 342 is connected to the liquid storage space 11 in the body 10, and the other is connected to the outside.

[0042] According to the water path assembly of the water heater of the embodiment of the utility model, when the external water source enters the tank 10 through the water inlet pipe 31 (directly enters the liquid storage space 11 of the tank 10 for heating, or enters the heat exchanger 20 in the tank 10 for heat exchange) or the water in the tank 10 flows out of the liquid storage space 11 through the water outlet pipe 32, the water will always pass through the circuitous water path formed by the central pipe 341 and the sleeve 342. The circuitous water path increases the resistance of the water in the path by extending the flow path of the water, so as to prevent the external water source from carrying an electric current exceeding the tolerance of the human body from entering the tank 10 or the water in the tank 10 from carrying an electric current exceeding the tolerance of the human body from flowing out to the outside, thereby causing a safety hazard.

[0043] It should be noted that in the related art, an anti-electrical wall component is generally provided on the water inlet pipe and the water outlet pipe of the water heater outside the inner tank (corresponding to the box 10 of the present application) to ensure that the current carried by the hot water flowing out of the inner tank or the cold water flowing into the inner tank is within a safe range. It is necessary to separately provide an independent anti-electrical wall component, resulting in a large number of parts of the water heater, a complex structure, and low installation efficiency.

[0044] According to the water path assembly of the water heater of the embodiment of the utility model, a circuitous water path is formed by the sleeved sleeve 342 and the central pipe 341. The circuitous water path is not only used for water inlet of the water inlet pipe 31 or water outlet of the water outlet pipe 32, but also used to extend the water flow path to form an anti-electricity wall. The anti-electricity wall function is integrated into the water inlet pipe 31 or the water outlet pipe 32, which effectively reduces the number of parts of the water heater, reduces the structural complexity, and improves the installation efficiency.

[0045] Here, “external” corresponds to a water source connected to the water inlet pipe 31 or a water connector connected to the water outlet pipe 32 .

[0046] In this embodiment, in the water inlet pipe 31, the water inlet end of the central pipe 341 is connected to the external water source, and the water outlet end of the sleeve 342 is connected to the box body 10; in the water outlet pipe 32, the water inlet end of the sleeve 342 is connected to the box body 10, and the water outlet end of the central pipe 341 is connected to the water connection. Of course, it is also possible to set the water inlet pipe 31 to have the water outlet end of the sleeve 342 connected to the external water source, and the water inlet end of the central pipe 341 connected to the box body 10; the same is true for the water outlet pipe 32, so as to ensure that the external water source enters the box body 10, or the water in the box body 10 flows out through the circuitous waterway.

[0047] In this embodiment, a central tube 341 is provided, and a sleeve 342 is sleeved on the outer periphery of the central tube 341. Figure 4 As shown, taking the water inlet pipe 31 as an example, the external water source flows from the inlet end of the central pipe 341 from bottom to top to the outlet end, and enters the circuitous waterway between the right sleeve 342 and the central pipe 341 through the outlet end, flows from top to bottom to the bottom side of the central pipe 341, enters the circuitous waterway between the left sleeve 342 and the central pipe 341 through the first connecting hole, and flows from bottom to top to the outlet end of the sleeve 342 and enters the box 10. That is, in this embodiment, by setting a sleeve 342, the water outlet path of the original water outlet pipe 32 is extended three times, ensuring the anti-electricity capability of the anti-electricity wall formed by the circuitous waterway. Of course, more sleeves 342 can be set to obtain a longer circuitous path.

[0048] According to one embodiment of the utility model, combined Figures 2 to 4 As shown, the central tube 341 and the sleeve 342 are suitable for vertical installation to the box body 10, and the top of the sleeve 342 is connected to the top of the central tube 341; in the water inlet pipe 31: the bottom end of the central tube 341 is the water inlet end, and the top end of the sleeve 342 is the water outlet end; in the water outlet pipe 32: the top end of the sleeve 342 is the water inlet end, and the bottom end of the central tube 341 is the water outlet end.

[0049] Combination Figure 4As shown, taking the water inlet pipe 31 as an example, the external water source flows from the inlet end of the central pipe 341 from bottom to top to the outlet end, and enters the circuitous waterway between the right sleeve 342 and the central pipe 341 through the outlet end, flows from top to bottom to the bottom side of the central pipe 341, enters the circuitous waterway between the left sleeve 342 and the central pipe 341 through the first connecting hole, flows from bottom to top to the outlet end of the sleeve 342 and enters the housing 10. The same is true for the water outlet pipe 32.

[0050] In this embodiment, the water outlet end or water inlet end of the central pipe 341 and the sleeve 342 are arranged at the end (top end or bottom end), and the water outlet path of the original water outlet pipe 32 is extended three times, so that the circuitous water path formed by the central pipe 341 and the sleeve 342 arranged in the vertical direction is the longest, which effectively improves the anti-electric effect.

[0051] In other embodiments, the center tube 341 and the sleeve 342 may also be installed horizontally or at a certain angle to the horizontal plane. Taking the horizontal installation of the center tube 341 and the sleeve 342 as an example, at this time, the water outlet end or the water inlet end of the center tube 341 and the sleeve 342 may be set at both ends of the horizontal side, thereby ensuring the length of the circuitous waterway.

[0052] According to one embodiment of the utility model, combined Figures 2 to 5 As shown, a plurality of dividing ribs 343 are provided in the casing 342, and the dividing ribs 343 divide the casing 342 into a plurality of water sections connected in series. When water flows, it passes through the plurality of water sections in sequence, and each time it passes through a water section, the length of the corresponding circuitous waterway increases by the length of one water section (in this embodiment, corresponding to the length of one central pipe 341), effectively extending the length of the circuitous waterway and improving the anti-electrical effect of the water inlet pipe 31 or the water outlet pipe 32.

[0053] In this embodiment, two partition ribs 343 are provided on both sides of the central tube 341, and the two partition ribs 343 divide the waterway between the sleeve 342 and the central tube 341 into two waterway sections on the left and the right. Of course, more partition ribs 343 may be provided to extend the length of the circuitous waterway by increasing the number of waterway sections.

[0054] According to one embodiment of the utility model, the partition rib 343 extends along the length direction of the sleeve 342. The extended partition rib 343 is simple to manufacture and easy to process. A first connecting hole (not shown in the figure) is provided at the end of the sleeve 342 corresponding to the partition rib 343 to connect adjacent waterway sections.

[0055] Combination Figure 4 and Figure 5As shown, in this embodiment, two partition ribs 343 are provided on both sides of the central tube 341. The two partition ribs 343 divide the water path between the sleeve 342 and the central tube 341 into two parts, a left part and a right part. Taking the water inlet pipe 31 as an example, when water flows in the water inlet pipe 31, the external water source flows from the inlet end of the central tube 341 from bottom to top to the outlet end, and enters the water path section on the right through the outlet end, flows from top to bottom to the bottom side of the central tube 341, enters the water path section on the left through the first connecting hole, and flows from bottom to top to the outlet end of the sleeve 342 to enter the box body 10.

[0056] In this embodiment, the position of the first communication hole corresponds to the inlet end of the sleeve 342, and is respectively located at both ends of the water inlet pipe 31, so as to ensure that the water entering the water path section can flow through a complete length of the central pipe 341. Of course, more number of partition ribs 343 can be provided, and correspondingly, the communication holes on the partition ribs 343 are staggered. For example, when four partition ribs 343 are provided, the communication holes of the first and third partition ribs 343 can be at the bottom, and the other two at the top, so that the four water paths formed by the four partition ribs 343 can be connected in sequence.

[0057] In other embodiments, the partition ribs 343 may also be arranged in other directions, such as extending spirally around the central tube 341 to form a spiral circuitous waterway.

[0058] According to one embodiment of the utility model, combined Figure 1 and Figure 4 As shown, the water inlet pipe 31 also includes a transverse pipe section 311, a water inlet 312 is provided on the first side of the transverse pipe section 311, a sleeve 342 is connected to the water inlet 312 of the transverse pipe section 311, and a temperature sensor 71 is provided on the second side of the transverse pipe section 311, and the first side and the second side are opposite to each other. This makes it possible for the connection component of the water inlet 312 and the temperature sensor 71 to not interfere with each other during installation, and the relative arrangement makes it possible for the water to flush the surface of the temperature sensor 71 when it flows out of the water inlet 312 through the circuitous waterway, so as to avoid the impurities in the water from accumulating on the surface of the temperature sensor 71 after long-term use or the scale from the surface of the temperature sensor 71 itself, so as to ensure the effectiveness of the detection of the temperature sensor 71.

[0059] According to one embodiment of the utility model, combined Figure 5 As shown, the anti-electricity water pipe 34 is an injection-molded one-piece pipe, the central pipe 341 is provided with a second connecting hole 346, the central pipe 341 is connected to the sleeve 342 through the second connecting hole 346, the sleeve 342 is provided with a blister port 347 corresponding to the second connecting hole 346, and the blister port 347 is installed with a blister plug 72.

[0060] The injection molding process is adopted to effectively improve the production efficiency of the anti-electricity water pipe 34. The vacuum forming port 347 is used to form a second connecting hole 346 during injection molding to achieve the connection between the central tube 341 and the sleeve 342. In actual use, the vacuum forming port 347 is installed with a vacuum forming plug 72 to prevent water from leaking from the vacuum forming port 347 and ensure the sealing effect of the water inlet pipe 31.

[0061] In this embodiment, the second connecting hole 346 is located in the top area of ​​the central tube 341, and correspondingly, the blister port 347 is also opened in the top area of ​​the sleeve 342; of course, the position of the blister port 347 is adjusted accordingly according to the position of the second connecting hole 346 between the central tube 341 and the sleeve 342 to realize the processing of the second connecting hole 346.

[0062] According to one embodiment of the utility model, combined Figure 1 and Figure 4 As shown, the water circuit assembly also includes an adapter 348, and the adapter 348 is plugged into the sleeve 342. Taking the water inlet pipe 31 as an example, the adapter 348 is provided so that the water inlet end of the water circuit assembly 30 as a whole can be specifically adjusted according to the actual spatial position to adapt to different installation environments, and the adapter 348 can be connected to different external water supply devices (such as faucets, water pumps) through different interfaces, effectively improving practicality.

[0063] In this embodiment, combined with Figure 1 As shown, the adapter joint 348 extends toward the rear side of the water heater, so that the external water supply component connected to the adapter joint 348 is hidden at the rear side of the water heater as much as possible, thereby improving the aesthetics.

[0064] According to one embodiment of the utility model, combined Figure 4 and Figure 7 As shown, the sleeve 342 is provided with a first sealing groove 349, a second sealing groove 350 and a snap-in groove 351 which are arranged in sequence along its length direction, the adapter joint 348 is provided with a buckle which cooperates with the snap-in groove 351, and the first sealing groove 349 and the second sealing groove 350 are respectively fixed with sealing rings.

[0065] By adopting the form of matching the plug buckle 126 and the clamping groove 351, the staff can quickly connect and disassemble the sleeve 342 and the adapter joint 348 by plugging and unplugging the plug buckle 126, thereby improving the installation efficiency; and the first sealing ring is sequentially arranged between the clamping groove 351 and the adapter joint 348 along the axis pointing to the direction of the waterway assembly 30 to realize the sealed connection between the sleeve 342 and the adapter joint 348, and the stability of the sealed connection is further improved by the second sealing ring. Of course, the number of sealing grooves can be adaptively adjusted according to actual needs; the sealing groove and the clamping groove 351 can also be opened in the adapter joint 348.

[0066] In this embodiment, the buckle 126 is "U"-shaped, and the snap-in grooves 351 are respectively opened on both sides of the outer wall of the sleeve 342, so that the two arms of the buckle 126 can be embedded in the snap-in grooves 351, and a through hole is opened on the adapter joint 348 corresponding to the position of the snap-in groove 351. The two arms of the buckle 126 pass through the first end of the through hole, the snap-in groove 351 and the second end of the through hole in turn, so as to realize the fixed connection between the sleeve 342 and the adapter joint 348.

[0067] According to the water heater of the second aspect of the utility model, Figures 1 to 3 As shown (for ease of display, Figure 3 The side panel 12 in the case has been made transparent), includes a housing 10, a water channel assembly 30 as in the above embodiment, a heat exchanger 20 and a circuit board; the housing 10 is provided with a liquid storage space 11; the water channel assembly 30 is installed in the housing 10, and the water channel assembly 30 is connected to the liquid storage space 11; the heat exchanger 20 is installed in the housing 10, and the heat exchanger 20 is used to exchange heat between water used by the user and water in the liquid storage space 11; the circuit board is fixed to the housing 10, and the circuit board is electrically connected to the water channel assembly 30.

[0068] In this embodiment, fresh water from the outside enters the heat exchanger 20 from the water inlet pipe 31 and exchanges heat with the heated liquid in the liquid storage space 11. The high-temperature water after heat exchange flows out from the outlet end of the heat exchanger 20 and is provided to the user through the water outlet pipe 32. The user's water is obtained after heat exchange with the liquid in the liquid storage space 11 through the heat exchanger 20, and does not contact the components (heater, valve body, etc.) in the liquid storage space 11 of the box body 10, thereby effectively ensuring the water quality of the user's water. At the same time, impurities or pollutants that may exist in the user's water will not cause pollution to the components in the liquid storage space 11 of the box body 10 (such as scale formation on the surface of the heating component), thereby effectively improving the service life of the water heater.

[0069] In this embodiment, the liquid in the liquid storage space 11 can be the same water source as that of the heat exchanger 20, or can be oil, phase change energy storage material, etc.

[0070] In this embodiment, the circuit board is used to control the operation of components on the water circuit assembly 30, such as a control valve, a pressure relief valve, etc.

[0071] According to one embodiment of the utility model, combined Figure 1 As shown, the box body 10 includes a side panel 12, and the water channel assembly 30 and the circuit board are installed in different areas of the side panel 12.

[0072] In this embodiment, as shown in the figure, a water channel assembly 30 is installed on the side panel 12, and the water channel assembly 30 is located in the lower area of ​​the side panel 12. The space reserved in the upper area of ​​the side panel 12 can be used to install a circuit board (not shown in the figure) to prevent the water channel assembly 30 from leaking and damaging the circuit board. Of course, the positional relationship between the water channel assembly 30 and the circuit board can be adaptively adjusted, such as setting the water channel assembly 30 on the rear side of the side panel 12 and the circuit board on the front side of the side panel 12, so that the user can observe the parameters of each component of the water heater displayed on the display on the circuit board.

[0073] In one embodiment, in combination Figure 6 As shown, the side panel 12 is integrally formed with an exhaust passage 121 , and the exhaust passage 121 connects the space above the liquid level in the liquid storage space 11 with the outside.

[0074] In this embodiment, during the heating process of the liquid in the liquid storage space 11, the liquid evaporates and forms steam that gathers above the liquid surface in the liquid storage space 11, and the steam is discharged from the liquid storage space 11 from the side of the side panel 12 through the exhaust channel 121, thereby ensuring that the pressure in the liquid storage space 11 is stable. By integrally forming the exhaust channel 121 with the side panel 12, the volume of the liquid storage space 11 is not occupied, and the storage capacity of the liquid is effectively increased while the external dimensions of the box body 10 remain unchanged, and the heat exchange efficiency between the liquid in the liquid storage space 11 and the water in the heat exchanger 20 is improved; moreover, the high-temperature steam of the exhaust channel 121 is discharged from the side of the side panel 12, which is hidden from the user's sight to improve the aesthetics while ensuring that the steam will not spray toward the user, thereby preventing the user from being scalded and improving the safety of the water heater.

[0075] In addition, in the present application, an exhaust passage 121 connecting the liquid storage space 11 and the outside is provided to ensure that the pressure in the liquid storage space 11 is similar to that in the outside and no additional pressure is generated on the inner wall of the box body 10. Therefore, the box body 10 does not need to be set to a pressure-bearing shape (such as a barrel shape), and the shape of the box body 10 can be adaptively adjusted according to the spatial layout requirements of the location of the water heater, thereby improving space utilization.

[0076] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention.
