[0051] 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.

[0052] 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.

[0053] 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, so that the water output from the water supply pipe can be treated by the filter 200 (such as filtering, purifying, mineralizing, etc.).

[0054] Embodiment 1, as Figure 1-Figure 9 As shown, in order to meet the requirement of convenient disassembly and assembly of the filter 200 , the water heater also includes an integrated water circuit assembly 300 , which is used to allow water supplied by an external water supply pipe to finally flow into the water inlet pipe 101 via the integrated water circuit assembly 300 .

[0055] Among them, 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 on the water channel connector 1, 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 is rotatably mounted on the water channel connector 1, and is provided with a first connecting hole 21 and a second connecting hole 22 on the installation component 2, and 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.

A mounting component 2 is sleeved on the water connection piece 1, and the mounting component 2 can rotate on the water connection piece 1, and the filter 200 is installed through the mounting component 2.

[0058] During use, water supplied by the external water supply pipe enters the water path 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 path connector 1 to the water inlet pipe 101.

[0059] 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.

[0060] Taking an electric water heater as an example, the electric water heater usually has a water tank, and the water connection member 1 is arranged at the lower part of the water tank and is arranged horizontally. In normal use, the filter 200 is flipped up and close to the bottom of the water tank to optimize the appearance effect; when disassembling and repairing, the filter 200 can be flipped to the bottom of the water tank, and the space under the water tank can be used for disassembly and assembly.

[0061] In some embodiments, in order to position the filter 200 in normal use and improve the stability of installation, an elastic pipe clamp 103 is further provided on the water heater body 100 , and the elastic pipe clamp 103 has a clamping entrance; the filter 200 is clamped on the elastic pipe clamp 103 .

[0062] Specifically, after the filter 200 is assembled on the mounting member 2, during normal use, the filter 200 is turned toward the water heater body 100 so that the filter 200 can be stuck in the elastic tube clamp 103. By clamping the filter 200 with the elastic tube clamp 103, the installation stability of the filter 200 can be improved.

[0063] In another embodiment, in order to improve the connection reliability 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, which protrudes from the outer wall of the mounting component 2 and has an annular structure, and surrounds the outside of the first connection hole 21 and the second connection hole 22; wherein the filter 200 is detachably arranged on the external connection portion 23.

[0064] 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 with the first connecting hole 21 and the second connecting hole 22 correspondingly after being connected with the filter 200.

[0065] 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 internal threads, and the outer circumference of the filter 200 is provided with external threads, and the requirements for threaded connection between the filter 200 and the external portion 23 are met by the cooperation of the external threads and the internal threads.

[0066] In some embodiments, the filter 200 can be threadedly mounted on the external connection portion 23. Specifically, the inner circumference of the external connection 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 is clamped with the second clamping portion.

[0067] 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 , and similarly, the external connection portion 23 is also formed on the outer wall of the mounting component 2 .

[0068] 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 hole 11 and the water inlet hole 12 are separated by the first annular rib 13;

[0069] A water outlet cavity is formed between the installation 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 installation component 2 and the water channel connector 1 on the other side of the first annular rib 13;

[0070] The first connection hole 21 is communicated with the corresponding water outlet hole 11 through the water outlet cavity, and the second connection hole 22 is communicated with the corresponding water inlet hole 12 through the water inlet cavity.

[0071] Specifically, in order to separate the water outlet 11 and the water inlet 12 to meet the requirement of independently separating the 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.

[0072] 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 .

[0073] In another embodiment, the water inlet and outlet holes 11 group 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;

[0074] The mounting component 2 covers the first annular rib 13 and the second annular rib 14 .

[0075] 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 .

[0076] The water outlet cavity and the water inlet cavity are isolated and separated by the cooperation of the first annular rib 13 and the second annular rib 14 with the inner cylinder wall of the mounting component 2. At the same time, the first annular rib 13 and the second annular rib 14 can further meet the installation requirement that the mounting component 2 can be rotatably mounted on the water channel connector 1, so as to meet the disassembly and assembly requirements of the filter 200.

[0077] 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 .

[0078] Specifically, the first annular rib 13 and the second annular rib 14 are covered with sealing rings, and the sealing rings can be abutted against the inner wall of the mounting component 2 to improve the connection sealing.

[0079] 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 installation component 2 , and the positioning portions are arranged on the outer sides of the adjacent second annular ribs 14 .

[0080] Specifically, the two ends of the mounting component 2 are in close contact with the second annular ribs 14 on the corresponding side through the positioning portions to achieve reliable mounting.

[0081] For example, the positioning portion at one end of the installation component 2 is a flange structure 24, the positioning portion at the other end of the installation component 2 is a detachable plug 25, and a plug hole for installing the plug 25 is also provided on the outer wall of the other end of the installation component 2. Specifically, when the installation component 2 is installed on the waterway connector 1, the installation component 2 is sleeved on the waterway connector 1 and moves toward the adjacent second annular rib 14, so that the flange structure 24 is abutted against the second annular rib 14; and the other second annular rib 14 is also covered by the installation component 2, and the plug 25 is inserted into the plug hole so that the plug 25 abuts against the outside of the other second annular rib 14 to achieve installation.

[0082] Alternatively, the outer walls of the two ends of the installation component 2 are respectively provided with insertion holes, and the insertion holes are provided with detachable plugs 25, and the plugs 25 are the positioning parts.

[0083] The filter 200 is installed by sleeved a rotatable mounting component 2 on the water connection 1. During normal use, the mounting component 2 is rotated to make the filter 200 flip over and abut 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 taken out of the elastic pipe clamp 103 and the mounting component 2 is rotated to make the filter 200 flip 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 to improve the convenience of use.

[0084] Embodiment 2, as Figure 1-Figure 9 As shown, in order to satisfy the user's convenience in switching different filters 200 to participate in water quality treatment, the water heater includes a water connection 1, a plurality of installation components 2 and a switching valve 4. At the same time, the water heater can be equipped with a plurality of filters 200.

The water channel connector 1 is provided with a plurality of groups of water inlet and outlet holes 11, each group of the water inlet and outlet holes 11 includes a water outlet hole 11 and a water inlet hole 12, the water outlet hole 11 is connected to the corresponding connecting channel 17, and the plurality of water inlet holes 12 are respectively connected to the water inlet channel 15, and the switching valve 4 is provided on the water channel connector 1 and is configured to switch the water inlet channel 15 to be connected to one of the connecting channels 17.

[0086] The installation component 2 is provided with a first connection hole 21 and a second connection hole 22 . The installation component 2 is arranged on the water channel connector 1 . The first connection hole 21 is connected to the corresponding water outlet hole 11 , and the second connection hole 22 is connected to the corresponding water inlet hole 12 .

[0087] Specifically, the filter 200 is installed on the water channel connector 1 through the corresponding installation component 2, and the water transported by the water inlet channel 15 enters the filter 200 in a 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.

[0088] Since the switching valve 4 can switch different connecting channels 17 to be connected with the water inlet channel 15, different filters 200 can be switched to participate in water treatment, so that users can conveniently switch different filters 200 for filtering treatment, thereby improving user convenience.

[0089] 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;

[0099] The mounting component 2 covers the first annular rib 13 and the second annular rib 14 .

[0100] Specifically, between the mounting component 2 and the water channel connector 1, the first annular rib 13 and the second annular ribs 14 on both sides thereof respectively form a water outlet cavity and a water inlet cavity. The first annular rib 13 and the second annular rib 14 cooperate with the inner cylinder wall of the mounting component 2 to separate the water outlet cavity and the water inlet cavity. At the same time, the first annular rib 13 and the second annular rib 14 can further meet the installation requirement that the mounting component 2 can be rotatably mounted on the water channel connector 1, so as to meet the assembly and disassembly requirements of the filter 200.

[0101] 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 pressed against the inner wall of the mounting component 2 ; the sealing rings can be pressed against the inner wall of the mounting component 2 to improve the connection sealing.

[0102] In some embodiments, an external portion 23 is further provided on the mounting component 2.

[0104] The adapter connecting pipe 3 is connected to the water channel connecting piece 1 , the first connecting pipe 31 is communicated with the water inlet channel 15 , and the second connecting pipe 32 is communicated with the water outlet channel 16 .

[0105] Specifically, since the water connection member 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 a transfer connection pipe 3 at one end of the water connection member 1, the connection with the external water supply pipe can be achieved through the first connection pipe 31, and the connection with the water inlet pipe 101 of the water heater body 100 can be achieved through the second connection pipe 32. The ports of the first connection pipe 31 and the second connection pipe 32 connected to the outside can be designed as needed, and the water connection member 1 only needs to be provided with corresponding water flow channels to reduce the manufacturing difficulty.

[0106] 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 .

The switching valve 4 includes a valve body 41, a valve stem 42, a turntable 43 and a water dividing plate 44. The water dividing 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 dividing 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.

[0109] Specifically, when in use, the user rotates the valve stem 42 to drive the rotary disk 43 to rotate, thereby connecting the other end of the connecting water tank 431 in the valve body 41 to the water outlet interface 442 or one of the connecting interfaces 443, thereby achieving the corresponding control requirements. The switching valve 4 is integrated on the water channel connector 1, making the overall structure more compact.

[0110] By providing multiple flow channels in the water channel connector 1 and configuring a switching valve 4 to switch and control the water inlet flow channel 15 to be connected with 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 water 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 filtering treatment to improve user convenience.
