DETAILED DESCRIPTION

[0021] To make clearer the purpose, the solution of the technique and the advantages of the present invention, the embodiments of the present invention will be described in detail below together with the accompanying drawings. It should be noted that the embodiments of this application and the features of the embodiments may be arbitrarily combined with each other. Petition 870250062366, dated 07 / 21 / 2025, p. 13 / 38 6 / 16 if there is no conflict.

[0022] The water heater supplied by embodiment of the present application, as shown in Figures 1 to 3, includes: a housing 100; a water inlet pipeline, a heating device and a water outlet pipeline sequentially connected, all arranged in the housing 100, the water outlet pipeline having a first water outlet; a first shower 400 positioned on the front side of the housing 100 and fixedly connected to the housing 100, and a water inlet of the first shower 400 communicating with the first water outlet. The water heater may be an instantaneous water heater.

[0023] A water inlet from the water inlet pipeline is connected to a tap water source; the water supplied by the tap water source is sprayed from the first shower head 400 after passing through the water inlet pipeline, the heating device, and the water outlet pipeline sequentially. During its passage through the heating device, the water is heated by the heating device to ensure that the water sprayed from the first shower head 400 is hot water. In this solution, the first shower head 400 is located on the front side of the housing 100 and is fixedly connected to the housing 100, and the water inlet of the first shower head 400 is in communication with the first water outlet. Such a water heater with the first shower head 400 has a simple and aesthetically pleasing structure.

[0024] In some examples, as shown in Figure 3, the water outlet includes a waterway switching valve 300. The waterway switching valve 300 has a water inlet communicating with the outlet of Petition 870250062366, dated 07 / 21 / 2025, page 14 / 38 7 / 16 water from the heating device. The waterway switching valve 300 also has a first water outlet (i.e., the first water outlet of the waterway outlet) and a second water outlet 310. The waterway switching valve 300 is configured so that at most one of the first water outlets and the second water outlet 310 is in communication with the water inlet of the waterway switching valve 300 (which may be the first water outlet being in communication with the water inlet of the waterway switching valve 300; or it may be the second water outlet 310 being in communication with the water inlet of the waterway switching valve 300; or it may be neither the first water outlet nor the second water outlet 310 being in communication with the water inlet of the waterway switching valve 300). The water heater also includes a second shower in communication with the second water outlet 310 via a hose.

[0025] The waterway switching valve 300 is configured to switch in a controlled manner between the water discharge from the second shower and the water discharge from the first shower 400. That is, when the water inlet of the waterway switching valve 300 is in communication with the first water outlet and the water inlet of the waterway switching valve 300 is not in communication with the second water outlet 310, the first shower 400 discharges water and the second shower does not discharge water, and at that moment, the user takes a shower using the first shower 400. When the water inlet of the waterway switching valve 300 is in communication with the second water outlet 310, and the water inlet of the waterway switching valve 300 is not in communication with the second water outlet 310, the first shower 400 discharges water and the second shower does not discharge water, and at that moment, the user takes a shower using the first shower 400. Petition 870250062366, dated 07 / 21 / 2025, page 15 / 38 8 / 16 communication with the first water outlet, the first shower head 400 does not discharge water, and the second shower head discharges water, and at that moment, the user takes a shower using the second shower head. The first shower head 400 is provided as a top spray shower and the second shower head is provided as a hand shower.

[0026] In some embodiments, the 300 waterway switching valve includes a valve support and a valve core, and the valve core is provided in the valve support and has a first communication position and a second communication position. The water inlet, the first water outlet and the second water outlet of the 300 waterway switching valve are located in the valve support.

[0027] When the valve core is located in the first communication position, the water inlet of the valve support is in communication with the first water outlet and the water inlet of the valve support is not in communication with the second water outlet 310, at this moment, the first shower 400 discharges water, the second shower does not discharge water, and the user takes a shower using the first shower 400. When the valve core is located in the second communication position, the water inlet of the valve support is not in communication with the first water outlet and the water inlet of the valve support is in communication with the second water outlet 310, at this moment, the first shower 400 does not discharge water, the second shower discharges water, and the user takes a shower using the second shower.

[0028] In some modalities, the core of Petition 870250062366, dated 07 / 21 / 2025, page 16 / 38 The 9 / 16 valve also has a closed position. When the valve core is in the closed position, the water inlet of the valve support is not in communication with the first water outlet, and the water inlet of the valve support is also not in communication with the second water outlet 310. At this time, no water is discharged from the first shower 400 and no water is discharged from the second shower.

[0029] In some embodiments, as shown in Figures 1 to 3, the water heater additionally includes a first adjustment rod 500. The waterway switching valve 300 is provided in a lower portion of the housing 100, the valve core is facing downwards, the first adjustment rod 500 is located below the waterway switching valve 300, the upper end of the first adjustment rod 500 is connected to the valve core. The first adjustment rod 500 is configured to actuate the valve core to move so as to switch between the first communication position and the second communication position.

[0030] Since the first showerhead 400 is fixed to the front side of the housing 100, the housing 100 needs to be fixed in a higher position to accommodate the normal use of the first showerhead 400. At this point, the user may not be able to adjust the waterway switching valve 300 because the position of the waterway switching valve 300 is too high. In this scheme, by adding the first adjustment rod 500, the user actuates the valve core through the first adjustment rod 500 to move in order to perform the switching between the first communication position and the second communication position of the valve core, so that the water heater Petition 870250062366, dated 07 / 21 / 2025, page 17 / 38 10 / 16 is more convenient to use.

[0031] The valve core may be provided rotatably in the valve support, and the valve core is actuated to rotate by the first adjusting rod 500 to perform switching between the first communication position and the second communication position. Alternatively, the valve core may be movably arranged in the valve support for up and down movement, and the valve core may be actuated to move up and down by the first adjusting rod 500 to perform switching between the first communication position and the second communication position, etc. All of the above may achieve the purpose of this application, and the purpose thereof does not deviate from the design idea of ​​the present invention, therefore it will not be repeated here, and all of them shall fall within the scope of protection of this application.

[0032] In some examples, as shown in Figure 3, the heating device includes a heating cup 710, a thyristor module 720, a power regulation module 730, and a pressure sensing module 740. The water inlet pipeline is in communication with the water outlet pipeline via the heating cup 710. The pressure sensing module 740 is supplied on the water inlet pipeline (or water outlet pipeline). The heating cup 710, the power regulation module 730, and the pressure sensing module 740 are all electrically connected to the thyristor module 720. The thyristor module 720 is supplied on the water inlet pipeline, and the thyristor module 720 is dissipated and cooled by the cold water flowing in the water inlet pipeline, so that the operational performance of the thyristor module 720 Petition 870250062366, dated 07 / 21 / 2025, page 18 / 38 11 / 16 can be better guaranteed.

[0033] The pressure sensing module 740 is configured to detect the actual water flow pressure within the water inlet pipeline, and the thyristor module 720 is configured to start and stop according to the actual water flow pressure. The power regulation module 730 is configured to input a control signal into the thyristor module 720. The thyristor module 720 is configured to control the current magnitude or the on / off time of the heating cup 710 according to the control signal at startup, so as to control the heating power of the heating cup 710 (i.e., the thyristor module 720 controls the heating power of the heating cup 710 according to the control signal at startup).In other words, the user can change the control signal by adjusting the power regulation module 730, and the thyristor module 720 adjusts the magnitude of the current or the on / off time of the heating cup 710 according to the control signal changed at startup, in order to perform the heating power adjustment of the heating cup 710.

[0034] It is possible that when the water flow pressure is greater than the pressure limit, the water heater is in a water discharge state and, at that moment, the thyristor module 720 starts and controls the heating cup 710 to heat the water inside the heating cup 710 with the heating energy adjusted by the user. When the water flow pressure is not greater than the pressure limit, the water heater is in a non-water discharge state and, at that moment, the thyristor module 720 stops and the heating cup 710 does not heat the water inside it. Petition 870250062366, dated 07 / 21 / 2025, page 19 / 38 12 / 16

[0035] In some embodiments, as shown in Figures 1 and 3, the water heater additionally includes a second adjustment rod 600. The second adjustment rod 600 is located below the housing 100 and connected to the power regulation module 730. That is, the power regulation module 730 is located in the lower portion of the housing 100, and the upper end of the second adjustment rod 600 is connected to the power regulation module 730. The second adjustment rod 600 is configured to actuate the power regulation module 730 to move so as to change the control signal, and the thyristor module 720 adjusts the heating energy of the heating cup 710 according to the control signal changed at startup, so as to achieve the objective of adjusting the outlet water temperature.

[0036] Since the first showerhead 400 is fixed to the front side of the housing 100, the housing 100 needs to be fixed in a higher position to accommodate the normal use of the first showerhead 400. At this point, the user may not be able to adjust the power regulation module 730 because the position of the power regulation module 730 is too high. In this scheme, by adding the second adjustment rod 600, the user drives the power regulation module 730 through the second adjustment rod 600 to move in order to change the control signal transmitted by the power regulation module 730 to the thyristor module 720. The thyristor module 720 adjusts the heating energy of the heating cup 710 according to the control signal changed at startup (the adjustment range of the heating energy of the heating cup 710 can be between 0 and the maximum heating energy), so that the water heater is more convenient to use. Petition 870250062366, dated 07 / 21 / 2025, page 20 / 38 13 / 16

[0037] The power regulation module 730 can be a power regulation module for rotational adjustment. The power regulation module 730 can be rotated by the second adjustment rod 600 to change the control signal transmitted by the power regulation module 730 to the thyristor module 720, thus achieving the adjustment of the heating energy of the heating cup 710.

[0038] In some embodiments, the heating cup 710 includes a cup body and a heating tube mounted on the cup body. The heating cup 710 has a simple structure and low manufacturing cost. The cup body can be provided as a metal cup body; or the cup body can be provided as a non-metallic cup body, such as a plastic or similar cup body. All of the above items can achieve the objective of this application, and their objective does not deviate from the design idea of ​​the present invention, therefore, they will not be repeated here, and all of them should fall within the scope of protection of this application.

[0039] In some examples, as shown in Figure 3, the water inlet pipeline includes a water inlet pipe 210 and a booster pump 220 mounted on the water inlet pipe 210. The booster pump 220 is used to increase the outlet water pressure and the outlet water flow velocity from the water heater when the water heater discharges water, so that the user has a better bathing experience.

[0040] The water inlet of the water inlet pipe 210 is located in the rear portion of the housing 100, the water outlet of the water inlet pipe 210 is connected to the heating cup 710 and the detection module of Petition 870250062366, dated 07 / 21 / 2025, page 21 / 38 14 / 16 pressure 740 is supplied on the water inlet pipe 210. The 740 pressure sensing module can be supplied as a pressure switch and the 720 thyristor module can be supplied as a thyristor board.

[0041] In some examples, as shown in Figures 1 to 3, the water heater additionally includes a transversely arranged (i.e., substantially horizontally arranged) connecting pipe 800 in the upper portion of the front side of the housing 100 and fixedly connected to the housing 100. A water inlet of the connecting pipe 800 is in communication with the first water outlet, and the first shower 400 is mounted on a water outlet of the connecting pipe 800.

[0042] That is, the rear end of the connecting pipe 800 is fixed to the upper portion of the front side of the housing 100, and the first shower head 400 is mounted on the lower portion of the front end of the connecting pipe 800. The connecting pipe 800 may be supplied as a metal pipe; or the connecting pipe 800 may be supplied as a non-metallic pipe, such as a plastic pipe or similar. All of the above items may achieve the objective of this application, and their objective does not deviate from the design idea of ​​the present invention, therefore, they will not be repeated here, and all of them shall fall within the scope of protection of this application.

[0043] In summary, in the solution of the technique provided by the embodiment of the present application, the water inlet pipeline is connected to the tap water source, the water supplied by the tap water source is sprayed from the first shower after passing through the water inlet pipeline, the heating device and the water outlet pipeline.
