It is necessary to regularly drain and clean the water heater. However, the entire process of draining and cleaning has many steps. If there is any omission in the operation, it may lead to the failure of the next operation or risks such as water leakage and scalding. Therefore, the user has a low cleaning frequency, or due to poor water quality, professional personnel need to be invited to operate, resulting in relatively high maintenance costs.

[0038] In view of the above problems, the following Figures 1 to 3 introduces the water heater of this application:

[0039] As Figure 1As shown in the figure, the water heater according to the present utility model includes a body 1, a water inlet pipe assembly 7, a water outlet pipe assembly 8 and a filter assembly 9. The body 1 is provided with an inner tank assembly 2. The inner tank assembly 2 is provided with a water storage cavity 3. The inner tank assembly 2 is further provided with a water inlet 4, a drain outlet 5 and a sewage outlet 6 communicating with the water storage cavity 3. The water inlet pipe assembly 7 passes through the water inlet 4. The water outlet pipe assembly 8 passes through the drain outlet 5. The filter assembly 9 passes through the sewage outlet 6. The water outlet of the filter assembly 9 and the water outlet of the water outlet pipe assembly 8 are connected to the same water use outlet 14.

[0040] For the water heater according to the embodiment of the present utility model, water is stored in the water storage cavity 3 of the inner tank assembly 2, and an external heating device or an internal heating device can heat the water in the water storage cavity 3. The water inlet pipe assembly 7 is connected to the water inlet 4 to supply cold water into the water storage cavity 3. After the water in the water storage cavity 3 is heated, it can be discharged through the water outlet pipe assembly 8 for the user to use. At the same time, the filter assembly 9 is connected to the sewage outlet 6 of the inner tank assembly 2. When the water heater needs to be drained of sewage, the sewage outlet 6 is opened, and the sewage will be discharged from the filter assembly 9. The water outlet of the filter assembly 9 and the water outlet of the water outlet pipe assembly 8 are connected to the same water use outlet 14, and the filtered hot water can be reused for cleaning or bathing, etc. In this way, when the water heater is drained of sewage, there is no need to wait for the hot water temperature to drop, and the filtered water can be reused, effectively improving the water utilization rate.

[0041] It can be understood that the body 1 includes components such as a housing and a bottom shell. The housing is used to protect the internal structure, and the bottom shell is used to fix the burner, heat exchanger and various control devices to form a whole. The internal structure includes, but is not limited to, the inner tank assembly 2, an electronic control unit, a temperature sensor, etc., for controlling gas supply and temperature adjustment. In addition, the water heater further includes safety devices such as an overheat protection device and a flame sensor to ensure safe use.

[0042] It should be noted that corresponding installation openings can be provided on the body 1 corresponding to the water inlet 4, the drain outlet 5 and the sewage outlet 6 of the inner tank assembly 2 to facilitate the installation of components such as the water inlet pipe assembly 7, the water outlet pipe assembly 8 and the filter assembly 9. The filter assembly 9 passes through the sewage outlet 6, and a part of it is located outside the inner tank assembly 2 to avoid occupying the water storage space of the water storage cavity 3. The filter assembly 9 can be installed inside the body 1 to avoid collision damage, or can be installed outside the body 1 to facilitate user observation and replacement.

[0043] According to an embodiment of the present utility model, the water outlet 14 is the only outlet for the water heater to drain water outward, and the water outlet 14 is used to connect to a water-using component. Optionally, the water-using component can be components such as a shower head, a spraying device, a water pipe, etc., facilitating the user to take a shower with the water discharged from the water outlet 14. It should be noted here that the only outlet for the water heater to drain water outward means that during the normal use of the water heater, the water in its water storage cavity 3 can only be discharged outward through the water outlet 14 for the user to use. Exemplarily, when the filter assembly 9 is disassembled, the water in the water storage cavity 3 can also be discharged through the sewage outlet 6.

[0044] In one embodiment, the water inlet pipe assembly 7 passes through the water inlet 4 from the bottom of the machine body 1, the water inlet pipe body of the water inlet pipe assembly 7 is inserted into the water storage cavity 3, and one end of the water inlet pipe body extends towards the center line direction of the water storage cavity 3. At the bottom of the water inlet pipe body, that is, one end of the water inlet pipe body adjacent to the inner wall of the water storage cavity 3, a plurality of water outlet holes are provided, and the plurality of water outlet holes are arranged in an array along the circumferential direction of the water inlet pipe body so that the water flows out evenly around the water inlet pipe body. At the same time, the water outlet pipe assembly 8 passes through the water outlet from the bottom of the machine body 1, the water outlet pipe body of the water outlet pipe assembly 8 is inserted into the water storage cavity 3, and one end of the water outlet pipe body extends towards the top of the water storage cavity 3. At the top of the water outlet pipe body, that is, one end of the water outlet pipe body away from the water outlet, a water outlet hole is provided so that the water in the water storage cavity 3 can only flow out when the water level reaches the position of the water outlet hole. In this way, the water heater takes in cold water from the bottom and discharges hot water from the top. Such a design facilitates the entry and heating of water, and the water outlet position is at the top, which can ensure that the hot water can flow out smoothly from the top after heating. This design not only facilitates the circulation and heating of water but also ensures the convenience during use.

[0045] As Figure 2 and Figure 3 shown, according to an embodiment of the present utility model, the filter assembly 9 includes a filter inlet pipe 10, a filter bottle 11, and a filter outlet pipe 12. One end of the filter inlet pipe 10 is connected to the sewage outlet 6; the filter bottle 11 is connected to the water outlet of the filter inlet pipe 10; one end of the filter outlet pipe 12 is connected to the filter bottle 11, and the other end is connected to the water outlet of the water outlet pipe assembly 8 at the same water outlet 14.

[0046] It can be understood that the water inlet end of the filtering water inlet pipe 10 is inserted into the water storage cavity 3, and the water outlet end is inserted into the filtering bottle 11. A filter element, such as filter cotton, filter net, etc., is provided in the filtering bottle 11. Optionally, a filter element socket can be installed in the filtering bottle 11 for installing and fixing the filter element so that the filter element can be replaced. In order to facilitate the discharge of scale deposited at the bottom of the water storage cavity 3, the water inlet end of the filtering water inlet pipe 10 is inserted into the water storage cavity 3, and its water inlet end is located at the bottom of the water storage cavity 3. In addition, one end of the filtered water outlet pipe 12 is inserted into the filtering bottle 11, and the other end is connected to the water using outlet 14. It can be understood that the water outlet of the water outlet pipe assembly 8 is also connected to the same water using outlet 14. The user uses hot water by connecting a water outlet pipe, a shower head assembly, and other structures to the water using outlet 14.

[0047] According to an embodiment of the present invention, the filtering assembly 9 further includes a switching valve 13. The switching valve 13 is provided with a water using outlet 14. The switching valve 13 is respectively connected to the water outlet pipe assembly 8 and the filtered water outlet pipe 12. The switching valve 13 communicates the water outlet pipe assembly 8 and the water using outlet 14, or the switching valve 13 connects the filtered water outlet pipe 12 and the water using outlet 14.

[0048] It can be understood that the switching valve 13 is a three-way valve that respectively communicates with the water using outlet 14, the water outlet pipe assembly 8, and the filtered water outlet pipe 12. Moreover, through the switching valve 13, either the water outlet pipe assembly 8 or the filtered water outlet pipe 12 can be selectively communicated with the water using outlet 14, so that hot water can flow out from either the water outlet pipe assembly 8 or the filtering assembly 9. Exemplarily, when the user normally uses the water heater, hot water flows out from the water outlet pipe assembly 8 to the water using outlet 14. When the water heater has been used for a period of time and needs to be drained of sewage, the connection can be switched to the filtered water outlet pipe 12 and the water using outlet 14, so that hot water flows out from the filtering assembly 9 to the water using outlet 14 to achieve sewage discharge, and the water passing through the filtering assembly 9 can also be used by the user for cleaning or bathing, etc.

[0049] According to an embodiment of the present invention, the switching valve 13 is a manual three-way ball valve, and the user can adopt a manual method, such as rotating the handle, to switch the water flow direction state. Optionally, the switching valve 13 is an electric ceramic valve or a solenoid valve, and the state is switched by a control module.

[0050] According to an embodiment of the present invention, the filtering bottle 11 is exposed outside the body 1. In this way, the user can observe the amount of scale residue at any time. At the same time, it is convenient to clean the scale residue in a timely manner or replace the filtering bottle 11, etc., without disassembling the body 1.

[0051] According to an embodiment of the present invention, the bottle body of the filtering bottle 11 is a transparent bottle. Exemplarily, the bottle body of the filtering bottle 11 is a glass bottle or a transparent plastic bottle, so that the user can directly observe the filtering situation in the filtering bottle 11, and thus clean the scale residue in a timely manner or replace the filtering bottle 11.

[0052] According to an embodiment of the present utility model, the filtering bottle 11 is detachably connected to the filtering water inlet pipe 10, and the filtering bottle 11 is detachably connected to the filtering water outlet pipe 12. It can be understood that the filtering bottle 11 is an encapsulated structure and can be detachably removed from the filtering water inlet pipe 10 and the filtering water outlet pipe 12, so as to facilitate the replacement of a new filtering bottle 11. Of course, the user can also remove the filtering bottle 11, open the filtering bottle 11 and take out the filter element, and remove the dirt in the filtering bottle 11 and the scale residue on the surface of the filter element, so that the filtering bottle 11 can be reused. The detachable connection method can be threaded connection, snap connection, etc., which is not limited herein.

[0053] According to an embodiment of the present utility model, the filtering assembly 9 is provided with filter media for improving water quality. Exemplarily, the filter media includes one or more of quartz sand filter media, anthracite filter media, fruit shell filter media, garnet filter media, ceramsite filter media, zeolite filter media, activated alumina balls, coconut shell activated carbon, fiber ball filter media, etc. The selection of these filter media depends on the specific water quality conditions and treatment objectives. By reasonable matching and use, the water quality can be effectively improved to meet different water use requirements.

[0054] According to an embodiment of the present utility model, the water heater further includes a magnesium rod assembly. The magnesium rod assembly passes through the sewage outlet 6, and a communication port communicating with the water storage cavity 3 is opened at the bottom of the magnesium rod assembly. One end of the filtering assembly 9 passes through the communication port to extend into the water storage cavity 3.

[0055] It can be understood that the magnesium rod assembly will generate deposits such as magnesium slag to protect the inner tank, and the deposits will be deposited at the bottom of the inner tank together. When the user operates the switching valve 13 to the sewage discharge function position and opens the water outlet, the water entering the water storage cavity 3 of the inner tank assembly 2 will flush the scale residue deposited at the bottom and discharge it through the sewage outlet 6 at the bottom of the magnesium rod assembly. When passing through the filter assembly, the solid scale residue will be collected in the filtering assembly 9, and the water will be purified by the filtering assembly 9, enter the switching valve 13 and be output to the user's hot water pipeline.

[0056] According to an embodiment of the present utility model, the water heater further includes a heater assembly 15. The heater assembly 15 is arranged in the inner tank assembly 2 and is used for heating the water in the water storage cavity 3. It can be understood that the heater assembly 15 includes a heating rod, and the heating rod extends into the water storage cavity 3. Specifically, the heating rod extends around the water inlet pipe body of the water inlet pipe assembly 7, so that the cold water entering at the water inlet pipe body can be heated in time, improving the heating efficiency.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit it.
