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.

[0052] The water circuit assembly 30 of the water heater according to the embodiment of the first aspect of the utility model includes a water inlet pipe 31, a water outlet pipe 32 and a sewage pipe 33; the water inlet pipe 31 is used to connect to the heat exchange tube 21 installed in the tank 10 of the water heater to supply water from an external water source to the heat exchange tube 21; the water outlet pipe 32 is used to connect to the heat exchange tube 21, and is used to transport the water after heat exchange to the water connection; the sewage pipe 33 is used to connect to the tank 10 to discharge the sewage in the tank 10; at least two of the water inlet pipe 31, the water outlet pipe 32 and the sewage pipe 33 are fixedly connected to pre-install the water circuit assembly 30.

[0053] Combination Figures 1 to 4 As shown, in the water circuit assembly 30 of the water heater of the utility model embodiment, fresh water from the outside enters the heat exchange tube 21 from the water inlet pipe 31, and exchanges heat with the heated liquid in the liquid storage space 11, and the high-temperature water after heat exchange flows out from the outlet end of the heat exchange tube 21 through the water outlet pipe 32 to the water joint; when the liquid in the liquid storage space 11 uses water from an external water source, some impurities contained in the external water source or the detachment of the surface of the components installed in the liquid storage space 11 (such as a heater, a valve body, etc.) will cause pollution to the water in the liquid storage space 11. By opening the sewage discharge channel, the water in the liquid storage space 11 carries the impurities and flows out from the sewage discharge channel to the outside, thereby achieving the cleaning of the inside of the liquid storage space 11.

[0054] It should be noted that in the related technology, the relevant pipelines on the water heater (water inlet pipe 31, water outlet pipe 32, sewage pipe 33, etc.) are usually independently connected to the inner tank of the water heater (corresponding to the box 10 of the present application), and the staff needs to install each pipeline separately, which leads to the problem of low assembly efficiency of the water heater.

[0055] The water circuit assembly 30 of the water heater of the embodiment of the utility model is formed into a whole by pre-installing at least two of the water inlet pipe 31, the water outlet pipe 32 and the sewage pipe 33. During the pre-installation process of the whole, other components (heater, valve body, etc.) can be installed simultaneously on the box 10, and then the water circuit assembly 30 is installed as a whole to the box 10, which effectively reduces the working hours required for assembling the box 10 and improves the assembly efficiency of the box 10.

[0056] In this embodiment, when the water circuit assembly 30 is installed on the box body 10, the sewage pipe 33 and the water inlet pipe 31 are fixedly pre-installed, and the water outlet pipe 32 is installed independently. Of course, when the interface arrangement positions on the box body 10 are different, such as when the interface corresponding to the sewage pipe 33 and the interface corresponding to the water outlet pipe 32 are closer, the spatial position of the sewage pipe 33 and the water outlet pipe 32 is closer at this time, so the sewage pipe 33 and the water outlet pipe 32 can also be pre-installed. The specific pre-installation combination is set based on the spatial position relationship between the sewage pipe 33, the water inlet pipe 31 and the water outlet pipe 32.

[0057] According to one embodiment of the utility model, combined Figures 1 to 4 and Figure 7 As shown, the water circuit assembly 30 of the water heater also includes an exhaust branch pipe 41, which is used to connect the top of the liquid storage space 11 in the box 10 with the outside world; 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 exhaust branch pipe 41 to ensure that the pressure in the liquid storage space 11 is stable. No additional pressure will be generated on the inner wall of the box 10, so the box 10 does not need to be set to a pressure-bearing shape (such as a barrel shape), and the shape of the box 10 can be adaptively adjusted according to the spatial arrangement requirements of the location of the water heater, thereby improving space utilization.

[0058] The exhaust branch pipe 41 is fixed to at least one of the water inlet pipe 31, the water outlet pipe 32 and the sewage pipe 33. The exhaust branch pipe 41 is included in the pre-installed water channel assembly 30, and when the water channel assembly 30 is installed in the box body 10, the exhaust branch pipe 41 is connected to the upper part of the liquid storage space 11, which simplifies the installation steps and improves the assembly efficiency.

[0059] In this embodiment, the exhaust branch pipe 41 is fixed to the outer side of the pipe wall of the water outlet pipe 32. Of course, based on the outlet position of the exhaust channel of the box body 10, the position of the exhaust branch pipe 41 can be adaptively adjusted to at least one of the water inlet pipe 31, the water outlet pipe 32 and the sewage pipe 33 to enhance the fixing effect while avoiding the exhaust branch pipe 41 being too long to affect the assembly.

[0060] According to one embodiment of the utility model, combined Figures 1 to 3 As shown, the sewage pipe 33 is fixed to the water inlet pipe 31, and the exhaust branch pipe 41 is fixed to the water outlet pipe 32. In this embodiment, since the sewage pipe 33 is close to the water inlet pipe 31, the outlet position of the exhaust channel is close to the water outlet pipe 32, the sewage pipe 33 is fixed to the water inlet pipe 31 to form a pre-installed whole, and the exhaust branch pipe 41 is fixed to the water outlet pipe 32. As mentioned above, the components and quantity of the pre-installed whole can be adaptively adjusted according to the spatial position relationship between different components (the outlet position of the water inlet pipe 31, the water outlet pipe 32 and the sewage pipe 33 and the exhaust channel).

[0061] According to one embodiment of the utility model, combined Figures 1 to 3 As shown, the exhaust branch pipe 41 includes a first horizontal pipe section 411 and a second horizontal pipe section 412 which are connected in sequence. The first horizontal pipe section 411 is connected to the interior of the box body 10, and the second horizontal pipe section 412 is connected to the outside. The end of the first horizontal pipe section 411 is fixed to the water outlet pipe 32. In this embodiment, the horizontally arranged first horizontal pipe section 411 makes the force direction of the exhaust branch pipe 41 (under the pressure of the box body 10) along the horizontal direction when the water channel assembly 30 is installed to the box body 10 as a whole in the horizontal direction, that is, the extension direction of the pipe wall of the exhaust branch pipe 41, thereby reducing the possibility of the exhaust branch pipe 41 breaking during the installation process, and the water outlet pipe 32 is fixedly connected at the end of the first horizontal pipe section 411, thereby improving the strength of the first horizontal pipe section 411 and realizing the pre-installation and fixation of the exhaust branch pipe 41 and the water outlet pipe 32, thereby simplifying the assembly steps of the water channel assembly 30.

[0062] In one embodiment, the sewage pipe 33 includes a third horizontal pipe section and a vertical pipe section 331 which are connected in sequence. The third horizontal pipe section is fixed to the water inlet pipe 31, and the vertical pipe section 331 is used to connect to the outside of the water heater. In this embodiment, the effect of the third horizontal pipe section is the same as that of the first horizontal pipe section 411 in the previous embodiment, which will not be repeated here. The vertical section is provided to ensure that the impurities in the sewage pipe 33 fall under the action of gravity and will not be accumulated in the vertical pipe section 331, thereby reducing the maintenance cost.

[0063] Of course, the first horizontal pipe segment 411 , the second horizontal pipe segment 412 , and the third horizontal pipe segment in the above two embodiments may also be set at a certain angle to the horizontal direction, which can be adaptively adjusted according to the orientation of the interface on the box body 10 .

[0064] According to one embodiment of the utility model, combined Figures 1 to 3 As shown, the water circuit assembly 30 of the water heater also includes a thermostatic valve 36, a filter tube 37, and a hot water pipe 38; the thermostatic valve 36 includes a first water inlet, a second water inlet and a first water outlet; the filter tube 37 and the thermostatic valve 36 are fixed, and the filter tube 37 is connected to the first water inlet, the filter tube 37 is connected to the water inlet pipe 31, and a pre-filter is arranged in the filter tube 37; the hot water pipe 38 and the thermostatic valve 36 are fixed, and the hot water pipe 38 is connected to the second water inlet; the water outlet pipe 32 is fixed to the thermostatic valve 36, and the water outlet pipe 32 is connected to the first water outlet.

[0065] The following is a description of the specific process of water flow in a water heater:

[0066] External cold water enters the water circuit assembly 30 from the water inlet pipe 31, and is filtered through the filter pipe 37 to prevent impurities from clogging the pipe and forming scale; the filtered cold water is partially passed into the heat exchange pipe 21 to exchange heat with the high-temperature liquid in the liquid storage chamber to form hot water, and the hot water flows out of the heat exchange pipe 21 and enters the thermostatic valve 36 from the second water inlet through the hot water pipe 38; the other part of the cold water directly enters the thermostatic valve 36 through the first water inlet; the hot water and the cold water are mixed in the thermostatic valve 36 according to the set ratio to form constant temperature water, and the constant temperature water flows out from the first water outlet to the water joint or the outside world for users to use.

[0067] In this embodiment, the filter tube 37, thermostatic valve 36 and hot water pipe 38 are integrated into the water circuit assembly 30, which not only provides constant temperature water to meet the user's needs, but also filters the water to increase the service life of the water heater and effectively improves the assembly efficiency of the water heater.

[0068] According to one embodiment of the utility model, combined Figures 1 to 3 As shown, the thermostatic valve 36 also includes a second water outlet, which is used to be connected to the water replenishment channel of the box body 10.

[0069] In this embodiment, during the heating process of the liquid in the liquid storage space 11, part of the liquid will vaporize to form steam and be discharged from the liquid storage space 11 (to ensure the pressure in the liquid storage space 11 is stable). Correspondingly, the liquid content in the liquid storage space 11 is reduced. The liquid in the liquid storage space 11 is replenished by setting a liquid replenishment channel to ensure the heat exchange efficiency between the liquid and the water in the heat exchange tube 2120; and water is used as the liquid in the liquid storage space 11, which is low in cost and easy to replenish.

[0070] In this embodiment, the second water outlet of the thermostatic valve 36 can be connected to the first water inlet. Either the second water inlet or the first water outlet can, correspondingly, add cold water, hot water or constant temperature water to the liquid storage space 11; when adding hot water or constant temperature water, it can ensure that the water temperature fluctuation in the liquid storage space 11 is small, thereby improving the heat exchange efficiency of the water heater.

[0071] According to the water heater of the second aspect of the utility model, Figure 4 As shown, it includes an outer shell 90, a box body 10 and a water channel assembly 30 as in the above embodiment, the box body 10 is installed in the outer shell 90, the box body 10 is provided with a liquid storage space 11, and the box body 10 includes a side panel 12; the water channel assembly 30 is installed on the side panel 12.

[0072] In this embodiment, the water channel assembly 30 is connected to the side panel 12 and does not occupy the space below the water tank (i.e., the user side space), thereby ensuring that all operations (installation, maintenance) are performed on the side of the water heater, which is not only convenient for installation but also easy for maintenance.

[0073] In this embodiment, combined with the attached Figure 4 As shown, taking a cubic box 10 as an example, the side panels 12 of the box 10 include a left side panel, a right side panel, a front side panel and a rear side panel. In addition, the box 10 also includes a top panel and a bottom panel, and the waterway assembly 30 is arranged on the right side panel. Of course, the side panel is not limited to the right side panel, and can also be a left side panel or other side panels.

[0074] According to one embodiment of the utility model, combined Figures 1 to 3 As shown, the water channel assembly 30 is integrally formed with a connecting ear 78 , and the connecting ear 78 is formed with a threaded hole, and the water channel assembly 30 is fixed to the box body 10 through the threaded hole.

[0075] Combination Figure 1 As shown, connecting ears 78 are provided on the water inlet pipe 31, the water outlet pipe 32 or the sewage pipe 33 of the water circuit assembly 30 near the side of the box body 10, and the connecting ears 78 are used to fix the water circuit assembly 30 and the box body 10, and the connecting ears 78 can transfer part of the weight of the water circuit assembly 30 to the box body 10, so as to avoid excessive force on the interface position where the pipe on the water circuit assembly 30 is connected to the box body 10, thereby ensuring the sealing effect of the interface position; and threaded holes can also be opened corresponding to the connecting ears 78 to improve the fixing effect between the two.

[0076] In this embodiment, each pipeline is provided with two connecting ears 78, and the angle formed by the two connecting ears 78 and the line connecting the center of the pipeline is close to 180°, which ensures that the force on both sides of the pipeline is uniform when fixed, thereby improving the sealing effect. Of course, based on the actual spatial arrangement of the pipeline, the number and position of the connecting ears 78 can be adaptively adjusted.

[0077] According to one embodiment of the utility model, combined Figure 6 to Figure 7As shown, the outer shell 90 includes a main body 91 and a side cover 92 detachably mounted on the main body 91, a mounting seat 17 is fixed to the box body 10 corresponding to the side cover 92, an insulating layer 18 is fixed between the mounting seat 17 and the side panel 12, the mounting seat 17 forms an assembly space 171 opening back to the box body 10, the water channel assembly 30 is installed in the assembly space 171, and the water channel assembly 30 is fixed to the side panel 12 through the mounting seat 17, and the connecting ear 78 is threadedly connected to the mounting seat 17.

[0078] In the present embodiment, during the maintenance process by the staff, since the water channel assembly 30 is installed in the assembly space 171 formed by the mounting seat 17, the mounting seat 17 and the water channel assembly 30 are installed as a whole to the box body 10, which is convenient for disassembly and positioning, and the staff only needs to open the side cover 92 to install and repair the water channel assembly 30, further facilitating maintenance; moreover, a side cover 92 is provided on the outer cover of the water channel assembly 30 to prevent external humid air from entering the outer shell 90 and affecting the service life of the water channel assembly 30, while achieving a hidden effect and improving the user's viewing experience.

[0079] Combination Figure 1 As shown, the connecting ear 78 can transfer part of the weight of the water channel assembly 30 to the mounting seat 17, thereby preventing the interface where the water channel assembly 30 and the housing 10 are connected from being subjected to excessive force, thereby ensuring the sealing effect of the interface.

[0080] In this embodiment, the heat insulation layer 18 is used to isolate the heat of the box body 10 to prevent the heat from being transferred to the water channel assembly 30, thereby affecting the working process and service life of both, and preventing the staff from being scalded during maintenance.

[0081] According to one embodiment of the utility model, the side panel 12 is pre-installed with a pipe joint 125, one of the pipe joint 125 and the water channel assembly 30 is provided with a plurality of sealing grooves 350 and fixing grooves 351, and the other is penetrated with a buckle 126, the sealing groove 350 is fixed with a sealing ring, and the fixing groove 351 and the buckle 126 are fixed.

[0082] In this embodiment, combined with Figures 1 to 3 and Figure 7 As shown, the outer periphery of the sealing ring fixed in the sealing groove 350 fits with the inner wall of the water channel assembly 30 (the water inlet pipe 31, the water outlet pipe 32, etc.) to achieve a sealing effect and prevent water leakage in the heat exchange tube 21 or the liquid storage space 11; and the buckle 126 and the fixing groove 351 are matched, and the staff can achieve a fixed connection between the pipe joint 125 and the water channel assembly 30 by plugging and pulling out the buckle 126, thereby effectively improving the assembly efficiency.

[0083] In this embodiment, a fixing groove 351 and two sealing rings are provided in sequence on the pipe joint 125 along the axis pointing in the direction of the water channel assembly 30. The two sealing rings play a double sealing role in the connection between the pipe joint 125 and the water channel assembly 30. Of course, the sealing groove 350 and the fixing groove 351 can also be set on the water channel assembly 30, and the number of sealing rings can be adaptively adjusted based on the actual position and space size.

[0084] In this embodiment, the buckle 126 is "U"-shaped, a fixing groove 351 is provided on the pipe joint 125, and the fixing grooves 351 are respectively opened on both sides of the outer wall of the pipe joint 125, so that the two arms of the buckle 126 can be embedded in the fixing grooves 351, and a through hole is opened on the water channel assembly 30 corresponding to the position of the fixing groove 351, and the two arms of the buckle 126 pass through the first end of the through hole, the fixing groove 351 and the second end of the through hole in turn, so as to realize the fixed connection between the pipe joint 125 and the water channel assembly 30.
