In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0026] like Figure 1 and Figure 2 As shown, the present application provides a water heater, which includes a water heater body 100. The water heater body 100 may be an electric water heater, a water tank of a heat pump water heater, or a water tank of a solar water heater.

[0027] When the water heater body 100 is used in a user's home, it is installed on a wall of the user's home according to installation requirements.

[0028] Among them, the water heater body 100 is equipped with a water inlet pipe 101 and a water outlet pipe 102. In order to improve the water quality of the water heater, a filter 200 can be added between the water inlet pipe 101 of the water heater and the water supply pipe in the user's home to treat the water output from the water supply pipe through the filter 200 (such as filtering, purification, mineralization, etc.).

[0029] Example 1, as Figures 1-9 As shown, in order to meet the requirement of easy disassembly and assembly of the filter 200, the water heater also includes an integrated water channel assembly 300, which is used to ensure that water supplied by an external water supply pipe finally flows into the water inlet pipe 101 through the integrated water channel assembly 300.

[0030] In which, the integrated water channel assembly 300 includes a water channel connector 1 and an installation component 2, the water channel connector 1 is a circular tube structure, and is provided with a group of water inlet and outlet holes 11, and the group of water inlet and outlet holes 11 includes a water outlet hole 11 and a water inlet hole 12, the installation component 2 is a sleeve structure and can be rotatably mounted on the water channel connector 1, and is provided with a first connecting hole 21 and a second connecting hole 22, the installation component 2 is arranged on the water channel connector 1, the first connecting hole 21 is connected to the corresponding water outlet hole 11, and the second connecting hole 22 is connected to the corresponding water inlet hole 12.

[0031] The water inlet hole 12 is connected to the water inlet pipe 101 , the filter 200 is detachably provided on the mounting component 2 , and the first connecting hole 21 and the second connecting hole 22 are respectively connected to the filter 200 .

[0032] Specifically, the water inlet pipe 101 of the water heater body 100 is additionally provided with a water connector 1, which is connected to the external water supply pipe via the water connector 1. The water connector 1 is provided with a mounting component 2, which is rotatable on the water connector 1 and through which the filter 200 is mounted.

[0033] During use, water supplied by the external water supply pipe enters the water channel connector 1 and is transported from the corresponding water inlet hole 12 to the second connection hole 22 and enters the filter 200 for water quality treatment. The water output from the filter 200 enters the first connection hole 21 and is transported to the water outlet hole 11. Finally, the water processed by the filter 200 is transported from the water channel connector 1 to the water inlet pipe 101.

[0034] When the filter 200 needs to be disassembled, the filter 200 can be pulled to drive the installation component 2 to rotate relative to the water connection 1, so that the filter 200 is arranged below the water heater body 100. In this way, the user or operator has enough space to disassemble the filter 200, thereby reducing the difficulty of disassembling the filter 200.

[0035] For example, an electric water heater typically has a water tank, with water connection member 1 positioned horizontally below the water tank. During normal use, filter 200 is flipped upward and positioned near the bottom of the water tank to optimize the appearance. During disassembly and maintenance, filter 200 can be flipped downward to utilize the space below the water tank for disassembly and installation.

[0036] In some embodiments, in order to position the filter 200 in normal use and improve installation stability, an elastic pipe clamp 103 is further provided on the water heater body 100. The elastic pipe clamp 103 has a card entrance; the filter 200 is clamped on the elastic pipe clamp 103.

[0037] Specifically, after the filter 200 is assembled on the mounting member 2, during normal use, the filter 200 is flipped toward the water heater body 100 so that the filter 200 can be clamped in the elastic pipe clamp 103. By clamping the filter 200 with the elastic pipe clamp 103, the installation stability of the filter 200 can be improved.

[0038] In another embodiment, in order to improve the connection reliability and assembly and disassembly convenience between the mounting component 2 and the filter 200, the mounting component 2 is further provided with an external connection portion 23. The external connection portion 23 protrudes from the outer wall of the mounting component 2 and has an annular structure. The external connection portion 23 surrounds the outside of the first connection hole 21 and the second connection hole 22; wherein the filter 200 is detachably mounted on the external connection portion 23.

[0039] Specifically, a raised external connection portion 23 is provided on the outer peripheral wall of the mounting component 2, and the external connection portion 23 will surround the outside of the first connecting hole 21 and the second connecting hole 22 to ensure that the filter 200 can be sealed and connected to the first connecting hole 21 and the second connecting hole 22 correspondingly after being connected to the filter 200.

[0040] In some embodiments, the filter 200 can be threadedly connected to the external portion 23. Specifically, the inner circumference of the external portion 23 is provided with an internal thread, and the outer circumference of the filter 200 is provided with an external thread. The external and internal threads cooperate to meet the requirements of the threaded connection between the filter 200 and the external portion 23.

[0041] In some embodiments, the filter 200 can be threadedly mounted on the external portion 23. Specifically, the inner circumference of the external portion 23 is provided with a first clamping portion, and the outer circumference of the filter 200 is provided with a second clamping portion, and the first clamping portion and the second clamping portion are clamped.

[0042] In another embodiment, the first connection hole 21 and the second connection hole 22 are formed on the outer wall of the mounting component 2 . Similarly, the external connection portion 23 is also formed on the outer wall of the mounting component 2 .

[0043] The water inlet and outlet holes 11 group further includes a first annular rib 13 formed on the outer wall of the water channel connector 1 , and the water outlet holes 11 and the water inlet holes 12 are separated by the first annular rib 13 ; A water outlet cavity is formed between the mounting component 2 and the water channel connector 1 on one side of the first annular rib 13, and a water inlet cavity is formed between the mounting component 2 and the water channel connector 1 on the other side of the first annular rib 13; The first connecting hole 21 is connected to the corresponding water outlet hole 11 through the water outlet cavity, and the second connecting hole 22 is connected to the corresponding water inlet hole 12 through the water inlet cavity.

[0044] Specifically, in order to separate the water outlet 11 and the water inlet 12 to meet the requirement of independent separation of water inlet and outlet of the filter 200, a first annular rib 13 is provided on the outer wall of the water channel connector 1 to separate the water outlet 11 and the water inlet 12 through the first annular rib 13.

[0045] Furthermore, after the installation component 2 is put on the water channel connector 1 , the water channel connector 1 will cover the first annular rib 13 , the water outlet hole 11 and the water inlet hole 12 .

[0046] In another embodiment, the group of water inlet and outlet holes 11 further includes two second annular ribs 14 formed on the outer wall of the water channel connector 1 , and the first annular rib 13 is located between the two second annular ribs 14 ; The mounting component 2 covers the first annular rib 13 and the second annular rib 14 .

[0047] Specifically, between the installation component 2 and the water channel connector 1 , a water outlet cavity is formed between the first annular rib 13 and one of the second annular ribs 14 , and a water inlet cavity is formed between the first annular rib 13 and the other second annular rib 14 .

[0048] The first annular ribs 13 and the second annular ribs 14 cooperate with the inner wall of the mounting member 2 to isolate the water outlet cavity from the water inlet cavity. Furthermore, the first annular ribs 13 and the second annular ribs 14 further ensure that the mounting member 2 can be rotatably mounted on the waterway connector 1, thereby accommodating the assembly and disassembly requirements of the filter 200.

[0049] In some embodiments, in order to improve water tightness, sealing rings are provided on the outer circumferences of the first annular rib 13 and the second annular rib 14 , and the sealing rings are in contact with the inner wall of the mounting component 2 .

[0050] Specifically, the first annular rib 13 and the second annular rib 14 are covered with sealing rings, which can be pressed against the inner wall of the mounting component 2 to improve the connection sealing.

[0051] In another embodiment, in order to facilitate the assembly of the integrated water channel assembly 300 , positioning portions are respectively provided at both ends of the mounting component 2 , and the positioning portions are arranged on the outside of the adjacent second annular ribs 14 .

[0052] Specifically, the two ends of the mounting component 2 are in contact with the second annular ribs 14 on the corresponding sides through the positioning portions to achieve reliable mounting.

[0053] For example, the positioning portion at one end of the mounting component 2 is a flange structure 24, and the positioning portion at the other end of the mounting component 2 is a detachable latch 25. The outer wall of the other end of the mounting component 2 is also provided with a socket for receiving the latch 25. Specifically, when the mounting component 2 is mounted on the waterway connector 1, the mounting component 2 is placed over the waterway connector 1 and moved toward the adjacent second annular rib 14 so that the flange structure 24 abuts against the second annular rib 14. The other second annular rib 14 is also covered by the mounting component 2, and the latch 25 is inserted into the socket so that the latch 25 abuts against the outside of the other second annular rib 14 to achieve installation.

[0054] Alternatively, the outer walls of both ends of the installation component 2 are respectively provided with insertion holes, and detachable plugs 25 are provided in the insertion holes, and the plugs 25 serve as the positioning parts.

[0055] The filter 200 is installed by sleeved with a rotatable mounting component 2 on the water channel connector 1. During normal use, the rotation of the mounting component 2 will cause the filter 200 to flip over and rest against the water heater body 100 and be stuck in the elastic pipe clamp 103; when disassembly and maintenance are required, the filter 200 is removed from the elastic pipe clamp 103 and the mounting component 2 is rotated to flip the filter 200 to the bottom of the water heater body 100. In this way, there is enough operating space to remove the filter 200 from the mounting component 2, thereby improving the convenience of use.

[0056] Example 2, as Figures 1-9 As shown, in order to meet the needs of users to conveniently switch different filters 200 to participate in water quality treatment, the water heater includes a water connection 1, multiple installation components 2 and a switching valve 4. At the same time, the water heater can be equipped with multiple filters 200.

[0057] The water channel connector 1 is provided with an inlet channel 15, an outlet channel 16 and multiple connecting channels 17. The water channel connector 1 is provided with multiple groups of inlet and outlet holes 11, each group of the inlet and outlet holes 11 includes an outlet hole 11 and an inlet hole 12, the outlet hole 11 is connected to the corresponding connecting channel 17, and multiple water inlet holes 12 are respectively connected to the water inlet channel 15. The switching valve 4 is provided on the water channel connector 1 and is configured to switch the water inlet channel 15 to connect with one of the connecting channels 17.

[0058] The mounting component 2 is provided with a first connecting hole 21 and a second connecting hole 22 . The mounting component 2 is provided on the water channel connector 1 . The first connecting hole 21 is connected to the corresponding water outlet hole 11 , and the second connecting hole 22 is connected to the corresponding water inlet hole 12 .

[0059] Specifically, the filter 200 is installed on the water channel connector 1 through the corresponding mounting component 2, and the water transported by the water inlet channel 15 enters the filter 200 in the working state. The corresponding connecting channel 17 is switched by the switching valve 4 so that the water output by the filter 200 in the working state is transported to the water outlet channel 16 through the first connecting hole 21 and the water outlet hole 11, and finally transported to the water inlet pipe 101 through the water outlet channel 16.

[0060] Since the switching valve 4 can switch different connecting channels 17 to connect with the water inlet channel 15, different filters 200 can be switched to participate in water quality treatment, so that users can conveniently switch different filters 200 for filtering treatment, thereby improving user convenience.

[0061] In one embodiment, the water inlet channel 15, the water outlet channel 16 and the plurality of connecting channels 17 extend along the length direction of the water flow connector; The water outlet 11 and the water inlet 12 are formed on the outer wall of the water flow connector; The mounting component 2 is a sleeve structure, and the first connecting hole 21 and the second connecting hole 22 are formed on the outer wall of the mounting component 2; Wherein, the installation component 2 is sleeved on the water flow connector.

[0062] Specifically, the mounting component 2 is sleeved on the water channel connector 1 to cover the water outlet holes 11 and the water inlet holes 12 in the corresponding water inlet and outlet hole 11 group.

[0063] In some embodiments, the group of water inlet and outlet holes 11 further includes a first annular rib 13 formed on the outer wall of the water channel connector 1 , and the water outlet hole 11 and the water inlet hole 12 are separated by the first annular rib 13 ; A water outlet cavity is formed between the mounting component 2 and the water channel connector 1 on one side of the first annular rib 13, and a water inlet cavity is formed between the mounting component 2 and the water channel connector 1 on the other side of the first annular rib 13; The first connecting hole 21 is connected to the corresponding water outlet hole 11 through the water outlet cavity, and the second connecting hole 22 is connected to the corresponding water inlet hole 12 through the water inlet cavity.

[0064] Specifically, the first annular rib 13 on the outer wall of the water channel connector 1 is used to separate the water outlet 11 and the water inlet 12.

[0065] In another embodiment, the group of water inlet and outlet holes 11 further includes two second annular ribs 14 formed on the outer wall of the water channel connector 1 , and the first annular rib 13 is located between the two second annular ribs 14 ; The mounting component 2 covers the first annular rib 13 and the second annular rib 14 .

[0066] Specifically, between the mounting component 2 and the waterway connector 1, the first annular rib 13 and the second annular ribs 14 on either side form a water outlet cavity and a water inlet cavity, respectively. The first and second annular ribs 13, 14 cooperate with the inner cylindrical wall of the mounting component 2 to isolate and separate the water outlet and water inlet cavities. Furthermore, the first and second annular ribs 13, 14 further ensure that the mounting component 2 can be rotatably mounted on the waterway connector 1, thereby accommodating the assembly and disassembly requirements of the filter 200.

[0067] Sealing rings are provided on the outer circumferences of the first annular rib 13 and the second annular rib 14 , and the sealing rings are in contact with the inner wall of the mounting component 2 , so that the sealing rings can be in contact with the inner wall of the mounting component 2 to improve the connection sealing.

[0068] In some embodiments, an external connection portion 23 is further provided on the mounting component 2. The external connection portion 23 protrudes from the outer wall of the mounting component 2 and has an annular structure. The external connection portion 23 surrounds the outside of the first connecting hole 21 and the second connecting hole 22. The external connection portion 23 is configured to connect the filter 200.

[0069] In another embodiment, a transition connecting pipe 3 is further included, wherein the transition connecting pipe 3 includes a first connecting pipe 31 and a second connecting pipe 32 connected together; The adapter connecting pipe 3 is connected to the water channel connector 1 , the first connecting pipe 31 is connected to the water inlet channel 15 , and the second connecting pipe 32 is connected to the water outlet channel 16 .

[0070] Specifically, since the water channel connector 1 needs to be connected to the external water supply pipe and the water inlet pipe 101 of the water heater body 100 respectively, by providing an adapter connecting pipe 3 at one end of the water channel connector 1, it can be connected to the external water supply pipe through the first connecting pipe 31 and connected to the water inlet pipe 101 of the water heater body 100 through the second connecting pipe 32. The ports for connecting the first connecting pipe 31 and the second connecting pipe 32 to the outside can be designed as needed, and the water channel connector 1 only needs to be provided with the corresponding water flow channels, thereby reducing the manufacturing difficulty.

[0071] In some embodiments, the switching valve 4 is further configured to switch the water inlet channel 15 to communicate with the water outlet channel 16 or one of the connecting channels 17 .

[0072] Specifically, the switching valve 4 functions to selectively connect the water inlet channel 15 to the water outlet channel 16 or one of its connecting channels 17, thereby meeting different water quality treatment requirements or allowing the water to enter the water inlet pipe 101 directly without being processed by the filter 200. The switching valve 4 can be a valve with a switching water channel connection function in conventional technology, such as a one-inlet, three-outlet valve.

[0073] In another embodiment, in order to integrate the switching valve 4 on the water channel connector 1, an installation groove 18 is provided at one end of the water channel connector 1, and the ports of the water inlet channel 15, the water outlet channel 16 and the connecting channel 17 are respectively located in the installation groove 18, and the switching valve 4 is provided in the installation groove 18. The switching valve 4 includes a valve body 41, a valve stem 42, a turntable 43 and a water diversion plate 44. The water diversion plate 44 is provided with a water inlet interface 441, a water outlet interface 442 and a connecting interface 443; the turntable 43 is provided with a connecting water tank 431; the turntable 43 is rotatably arranged in the valve body 41, the valve stem 42 extends into the valve body 41 and is used to drive the turntable 43 to rotate, the water diversion plate 44 is arranged at the end of the valve body 41 and is located on the outside of the turntable 43, one end of the connecting water tank 431 is connected to the water inlet interface 441, and the other end of the connecting water tank 431 is selectively connected to the water outlet interface 442 or one of the connecting interfaces 443; the water inlet interface 441 is sealed and connected to the water inlet channel 15, the water outlet interface 442 is sealed and connected to the water outlet channel 16, and the connecting interface 443 is sealed and connected to the connecting channel 17.

[0074] Specifically, during use, the user rotates the valve stem 42 to drive the rotation of the rotary disk 43, thereby connecting the other end of the connecting water channel 431 in the valve body 41 to the water outlet port 442 or one of the connecting ports 443, thereby achieving the corresponding control requirements. The switching valve 4 is integrated into the water channel connector 1, making the overall structure more compact.

[0075] By setting up multiple flow channels in the water channel connector 1 and configuring a switching valve 4 to switch and control the connection between the water inlet flow channel 15 and one of the connecting flow channels 17, the incoming water can be treated through the corresponding filter 200, and the treated water will flow into the outlet flow channel 16 through the corresponding connecting flow channel 17. When it is necessary to switch the filter 200, the other connecting flow channel 17 is connected by the switching valve 4 to switch to another filter 200 for water treatment. There is no need for the user to disassemble and replace different filters 200, and it is convenient to switch different filters 200 for filtration treatment to improve user convenience.
