Description

Technical Field

[0001] This utility model relates to an electric toilet, and more particularly to an electric toilet with an improved water circuit structure, which has the IPC classification number E03D 9 / 08 (2006.01). Background Technology

[0002] Existing electric toilets typically use instant electric heaters (electric heaters that heat the washing water only momentarily during use) to heat the water used for washing. However, this is difficult to meet the demand for large water volumes in winter or low-temperature environments. In such cases, the power of the instant electric heater needs to be designed to be very high (above 2000W). Because the instant electric heater has a large power, when used in areas with a mains voltage of 110V, the operating current of the electric toilet is too high, posing a safety hazard.

[0003] For relevant terminology and common knowledge, please refer to the "Mechanical Engineering Handbook" and "Electrical Engineering Handbook" published by China Machine Press in 1983 or 1997, as well as the national standard GB / T 23131-2019 "Electric Toilet Seats for Household and Similar Purposes". Utility Model Content

[0004] To address the problems described in the background section, this utility model provides the following technical solution:

[0005] An electric toilet with an improved water circuit structure includes a water tank, an instant electric heater located downstream of the water tank, a water pump, and a cleaning device. The toilet is characterized by further including a water mixing device, a first water distribution valve located upstream of the water tank, and a water heating device for heating the liquid in the water tank. The inlet of the first water distribution valve is connected to a water source, one of its outlets is connected to the water tank, and the other of its outlet is connected to the water mixing device. The water mixing device has a first inlet connected to the outlet of the water tank, a second inlet connected to the second outlet of the first water distribution valve, and a mixed water outlet connected to the inlet of the instant electric heater or the water pump.

[0006] This utility model discloses an electric toilet with an improved water circuit structure. It uses a water heating device inside the tank to heat and store the water. The hot water from the tank is then introduced into a mixing device for initial mixing and temperature adjustment. This mixed warm water is then precisely heated by an instant electric heater, finally producing warm water that meets user requirements, which is then sprayed out from the washing device for washing. Compared to existing electric toilets, this improved water circuit structure allows for the continuous spraying of precisely heated water even in low-temperature environments using a low-power instant electric heater, enhancing both user experience and safety.

[0007] Furthermore, the water pump inlet is connected to the outlet of the instantaneous electric heater, and its outlet leads to the cleaning device.

[0008] Furthermore, the inlet of the instantaneous electric heater is connected to the outlet of the water pump, and its outlet leads to the cleaning device.

[0009] Furthermore, the water heating device is an electric heating element installed inside the water tank.

[0010] Furthermore, the water heating device includes a second water distribution valve located upstream of the spray bar of the cleaning device. The inlet of the second water distribution valve is located downstream of the water pump and the instantaneous electric heater, and one of its outlets leads to the water tank.

[0011] Furthermore, the electric toilet with the improved water circuit structure also includes a flow restrictor valve, which is located upstream of the first water distribution valve; or connected in series between the first water distribution valve and the second inlet of the mixing water device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] See Figure 1 This utility model discloses an electric toilet with an improved water circuit structure. The electric toilet includes a water tank 100, a water heating device for heating the liquid in the water tank 100, an inlet valve 920 and a first water distribution valve 600 located upstream of the water tank 100, an instant electric heater 200 located downstream of the water tank 100, a water pump 300, a cleaning device 400, and a water mixing device 500. The water tank 100 includes a water inlet 110 for supplying water and a water outlet 120 for supplying water. The cleaning device... 400 includes a spray bar 420 for washing; the mixing water device 500 is a thermostatic valve, which includes a mixed water outlet 530 for water discharge and a first inlet 510 and a second inlet 520 for water intake; the first water distribution valve 600 is a valve with one inlet and two outlets or one inlet and multiple outlets. Preferably, the first water distribution valve 600 of this utility model is a valve with one inlet and two outlets, which includes a water distribution valve inlet 610 for water intake and a first water distribution valve outlet 620 and a second water distribution valve outlet 630 for water discharge.

[0021] In this embodiment, the water circuit connection of the electric toilet is as follows: the inlet valve 920 is located upstream of the first diverter valve 600, its inlet is connected to the water source, and its outlet is connected to the inlet 610 of the first diverter valve via a water pipe. The first outlet 620 of the first diverter valve 600 is connected to the inlet 110 of the water tank via a water pipe. The second outlet 620 of the first diverter valve is connected to the second inlet 520 of the mixing device via a water pipe. The first inlet 510 of the mixing device is connected to the outlet 120 of the water tank via a water pipe. Its outlet 530 is connected to the inlet 210 of the instant electric heater 200 via a water pipe. The outlet 220 of the instant electric heater 200 is connected to the inlet 310 of the water pump 300 via a water pipe. The outlet 320 of the water pump 300 is connected to the cleaning device 400 via a water pipe. The working principle of the electric toilet with improved water circuit structure of this utility model is as follows: In standby mode, the water heating device in the water tank works to adjust the temperature of the water in its cavity to a specified stable temperature (such as 40℃-50℃). When the user uses the spray washing function, the water heating device stops working, the first water distribution valve 600 adjusts its first water distribution valve inlet 610 to be connected to the first water distribution valve outlet 620, the water pump 300 works, the source water enters the mixing water device 500 after passing through the first water distribution valve 630 and is mixed with the warm water from the water tank 100 before entering the instant electric heater 300 for precise heating, and the water flowing out of the instant electric heater outlet 310 of the instant electric heater 300 is pressurized by the water pump 300 and sprayed out from the cleaning device 400 to achieve spray washing. Compared to existing electric toilets, this improved water system structure electric toilet uses a low-power instant electric heater to spray precisely heated water for extended periods in low-temperature environments, enhancing the user experience while ensuring safety.

[0022] See Figure 1 As a preferred embodiment, the water heating device of this utility model is an electric heating tube 710 installed in the accommodating cavity of the water tank 100. When working, the electric heating tube 710 directly contacts the liquid in the water tank 100 and heats it. It has a simple structure and high heating efficiency.

[0023] Furthermore, see Figure 1 The electric toilet in this embodiment also includes a flow-limiting valve 910, which is located upstream of the first water distribution valve 600. This valve limits the flow of water from the water source to prevent excessive inlet water pressure, which could cause excessive water pressure ejected from the cleaning device 400 and negatively impact the user experience. Alternatively, in other embodiments, the flow-limiting valve 910 can be connected in series on the water pipe connecting the second outlet 620 of the first water distribution valve and the second inlet 520 of the mixing water device.

[0024] Example 2:

[0025] See Figure 2 This utility model provides a second embodiment of an electric toilet with an improved water circuit structure. The difference between this embodiment and embodiment 1 is the water circuit location of the water pump 300. In this embodiment, the water pump 300 is located upstream of the instantaneous electric heater 300. Specifically, in this embodiment, the water pump inlet 310 of the water pump 300 is connected to the mixed water outlet 520 of the mixing water device 500 via a water pipe, and its water pump outlet 320 is connected to the instantaneous electric heater inlet 210 of the instantaneous electric heater 200 via a water pipe. This design increases the suction force on the liquid in the mixing water device 500, facilitating the extraction of liquid from the water tank 100 to the mixing water device 500 for temperature adjustment.

[0026] Example 3:

[0027] See Figure 3 This utility model provides a third embodiment of an electric toilet with an improved water circuit structure. Except for the structure of the water heating device, the structure of this embodiment is the same as that of Embodiment 1, and will not be described again here.

[0028] The water heating device in this embodiment includes a second water distribution valve 410 located upstream of the spray bar 420 of the cleaning device 400. The second water distribution valve inlet 410 of the second water distribution valve 410 is located downstream of the water pump 300 and the instant electric heater 200. One of the outlets of the second water distribution valve 410 leads to the water tank 100, and the other outlet of the second water distribution valve 410 is connected to the cleaning device 400. Specifically, when the electric toilet of this embodiment is installed, the second water distribution valve inlet 411 of the second water distribution valve 410 is connected to the water pump outlet 320 through a water pipe, the first outlet 411 of the second water distribution valve 410 is connected to the water tank inlet 110 through a water pipe, and the other outlet is connected to the cleaning device 400 through a water pipe. The working principle of the electric toilet in this embodiment is as follows: In the standby state, the second water distribution valve 400 connects its inlet 411 with the first outlet 412 of the second water distribution valve. The water pump 300 and the instant electric heater 200 are turned on. The water in the water tank 100 flows out from the water tank outlet 120, is heated by the instant electric heater 200, passes through the water pump 300 and the second water distribution valve 420 of the cleaning device 400, and then flows back to the water tank 100, thereby achieving temperature regulation of the water in the water tank 100. When the user activates the spray washing function, the second water distribution valve 400 adjusts its outlet to be connected to the spray bar 420, and the first water distribution valve 600 adjusts its inlet to be connected to the second outlet 630 of the first water distribution valve. The mixing water device 500 mixes the warm water from the water tank 100 and the water from the water source once for temperature adjustment, and then passes it through the instant electric heater 200 for precise temperature adjustment before finally spraying it out from the spray bar 420 of the cleaning device 400. In this embodiment, the second water distribution valve 400 can replace the electric heating tube 710 to heat the liquid in the water tank 100. This design avoids the formation of scale caused by heating water in the water tank.
