[0035] After the water heater is used for a period of time, scale and other sundries will be generated in the water storage cavity. The existing live water pollution scheme has many complex user operation steps and long waiting time. The water temperature in the water heater needs to be reduced to avoid scalding of personnel when draining water, and then the next stage of operation can be continued. At the same time, the whole water in the inner tank needs to be drained, because the water contains scale and magnesium residue, etc., the drained sewage cannot be reused, causing waste of water resources.

[0036] The water heater will deposit scale in the inner tank during use, and the magnesium rod assembly will generate magnesium residue and other deposits to protect the inner tank, which will be deposited together at the bottom of the inner tank. The water heater needs to be drained and cleaned regularly, and the whole process of draining and cleaning has many steps, and any omission will cause the next operation to fail or have the risk of water leakage, scalding, etc. Therefore, the user has low cleaning frequency, or needs to ask a professional to operate due to poor water quality, resulting in high maintenance and maintenance costs.

[0037] In view of the above problems, the water heater of the present application is described below in combination with FIGS. 1 to 3.

[0038] As shown in Fig. 1, the water heater according to the present application comprises 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 container assembly 2, which is provided with a water storage cavity 3, and is further provided with a water inlet 4, a water outlet 5 and a sewage outlet 6, which are communicated with the water storage cavity 3. The water inlet pipe assembly 7 is arranged in the water inlet 4. The water outlet pipe assembly 8 is arranged in the water outlet 5.

The water inlet pipe assembly 7 is connected to the water inlet 4 to provide cold water to the water storage cavity 3. After the water in the water storage cavity 3 is heated, the water can be discharged through the water outlet pipe assembly 8 for use by the user. At the same time, the filter assembly 9 is connected to the sewage outlet 6 of the inner container assembly 2. When the water heater needs to be drained, the sewage outlet 6 is opened, and the sewage is 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 outlet 14, and the filtered hot water can be used for cleaning or bathing, etc. In this way, when the water heater is drained, there is no need to wait for the temperature of the hot water to decrease, and the filtered water can be reused, effectively improving the utilization rate of water.

[0040] It can be understood that the body 1 comprises a shell, a bottom shell and other components. The shell is used to protect the internal structure, and the bottom shell is used to fix the burner, the heat exchanger and various control devices, so as to become a whole.

In addition, the water heater also comprises safety devices, such as an overheat protection device, a flame sensor and the like, to ensure safe use.

[0041] It should be noted that the body 1 can be provided with corresponding mounting ports corresponding to the water inlet 4, the water outlet 5 and the sewage outlet 6 of the inner container assembly 2, so as to facilitate the installation of the water inlet pipe assembly 7, the water outlet pipe assembly 8 and the filter assembly 9. The filter assembly 9 is arranged in the sewage outlet 6, and part of the filter assembly 9 is located outside the inner container assembly 2, so as to avoid occupying the water storage space of the water storage cavity 3. The filter assembly 9 can be arranged inside the body 1 to avoid collision and damage, or can be arranged outside the body 1 to facilitate observation and replacement by the user.

[0042] According to one embodiment of the present application, the water outlet 14 is the only outlet for the water heater to discharge water, and the water outlet 14 is used to connect a water using device. Optionally, the water using device can be a shower, a spraying device, a water pipe or the like, so as to facilitate the user to take a shower or a bath by using the water discharged from the water outlet 14. It should be noted that the only outlet for the water heater to discharge water means that during normal use of the water heater, the water in the water storage cavity 3 can only be discharged to the outside through the water outlet 14 for the user to use. For example, when the filter assembly 9 is disassembled, the water in the water storage cavity 3 can also be discharged through the drain hole 6.

[0043] In one embodiment, the water inlet pipe assembly 7 is arranged in the water inlet 4 through the bottom of the 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 of the water storage cavity 3. A plurality of water outlet holes are arranged on the bottom of the water inlet pipe body, i.e. the end of the water inlet pipe body adjacent to the inner wall of the water storage cavity 3, and the plurality of water outlet holes are arranged in an array along the circumference of the water inlet pipe body, so as to uniformly discharge water around the water inlet pipe body. Meanwhile, the water outlet pipe assembly 8 is arranged in the water outlet through the bottom of the 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. A water outlet hole is arranged on the top of the water outlet pipe body, i.e. the end of the water outlet pipe body away from the water outlet, so that the water in the water storage cavity 3 can only be discharged when the water level reaches the position of the water outlet hole. In this way, the water heater can be used to introduce cold water from the bottom and discharge hot water from the top, which facilitates the introduction and heating of water, and the position of the water outlet is located at the top, which can ensure that the hot water can be smoothly discharged from the top after being heated. This design not only facilitates the circulation and heating of water, but also ensures the convenience during use.

[0044] As shown in FIGS. 2 and 3, according to one embodiment of the present application, the filter assembly 9 includes a filter water inlet pipe 10, a filter bottle 11 and a filter water outlet pipe 12. One end of the filter water inlet pipe 10 is connected to the drain hole 6; the filter bottle 11 is connected to the water outlet of the filter water inlet pipe 10; one end of the filter water outlet pipe 12 is connected to the filter bottle 11, and the other end is connected to the same water outlet 14 as the water outlet of the water outlet pipe assembly 8.

[0045] 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. The filtering bottle 11 is provided with a filter element, such as filter cotton, filter screen, etc. Alternatively, a filter element socket can be arranged in the filtering bottle 11 for mounting 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 the water inlet end is located at the bottom of the water storage cavity 3. In addition, one end of the filtering water outlet pipe 12 is inserted into the filtering bottle 11, and the other end is connected with the water outlet 14. It can be understood that the water outlet of the water outlet pipe assembly 8 is also connected with the same water outlet 14, and the user uses hot water by connecting the water outlet pipe, shower assembly and other structures with the water outlet 14.

[0046] According to an embodiment of the present application, the filtering assembly 9 further comprises a switching valve 13 provided with a water outlet 14. The switching valve 13 is connected with the water outlet pipe assembly 8 and the filtering water outlet pipe 12 respectively. The switching valve 13 communicates the water outlet pipe assembly 8 with the water outlet 14, or the switching valve 13 communicates the filtering water outlet pipe 12 with the water outlet 14.

[0047] It can be understood that the switching valve 13 is a three-way valve, which communicates the water outlet 14, the water outlet pipe assembly 8 and the filtering water outlet pipe 12 respectively. Through the switching valve 13, the water outlet pipe assembly 8 and the filtering water outlet pipe 12 can be selectively communicated with the water outlet 14, so that hot water can flow out from one of the water outlet pipe assembly 8 and the filtering assembly 9. For example, when the user normally uses the water heater, hot water flows out from the water outlet pipe assembly 8 to the water outlet 14. When the water heater is used for a period of time and needs to be discharged, the filtering water outlet pipe 12 can be switched to communicate with the water outlet 14, so that hot water flows out from the filtering assembly 9 to the water outlet 14, achieving the discharge. The water after passing through the filtering assembly 9 can also be used by the user for cleaning or bathing, etc.

[0048] According to an embodiment of the present application, the switching valve 13 is a manual three-way ball valve, and the user can manually switch the water flow direction, such as by rotating the handle. Alternatively, the switching valve 13 is an electric ceramic valve or electromagnetic valve, and the state switching is controlled by a control module.

[0049] According to an embodiment of the present application, 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, and it is convenient to clean the scale residue or replace the filtering bottle 11, without the need to disassemble the body 1.

[0050] According to an embodiment of the present application, the bottle body of the filtering bottle 11 is a transparent bottle. For example, 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 condition in the filtering bottle 11, thereby cleaning the scale residue or replacing the filtering bottle 11 in time.

[0051] According to one embodiment of the present application, the filter bottle 11 is detachably connected with the filter inlet pipe 10, and the filter bottle 11 is detachably connected with the filter outlet pipe 12. It can be understood that the filter bottle 11 is a sealed structure, and can be integrally detached from the filter inlet pipe 10 and the filter outlet pipe 12, so as to replace a new filter bottle 11. Of course, the user can also detach the filter bottle 11, open the filter bottle 11 and take out the filter core, clean the dirt in the filter bottle 11 and the dirt on the surface of the filter core, so that the filter bottle 11 can be reused. The detachable connection mode can be threaded connection, buckle connection, etc., which is not limited here.
