Description

Technical Field

[0001] This application claims the priority of a Chinese patent application filed with the Chinese Patent Office on August 18, 2022, with an application number of 202210995183.X and an invention title of "Washing System and Toilet Device", and the content thereof should be understood to be incorporated into this application by reference.

[0002] This text relates to the field of bathroom technology, but is not limited thereto, and particularly relates to a washing system and a toilet device.

Background Art

[0003] Currently, smart toilets equipped with commercially available pump washing systems are increasingly gaining consumer support for their stable washing performance. This type of washing system can meet the washing under the high water pressure operation condition of the water pipe in terms of washing performance, and can also be unaffected by the pipeline water pressure fluctuation when the water pipe is at low pressure.

[0004] However, this type of washing system also has several drawbacks. One of the prominent drawbacks is that when the operating condition is abnormal, for example, in the case of a power outage operation condition, relatively large power is required for pump drive. Therefore, the pump cannot be driven when the power grid is in a power outage state, and thus washing in a power outage state cannot be realized.

The bowl body 11 includes a water seal area 110 communicating with the waste discharge passage 12, the water seal area 110 being used to store a water column of a certain height to resist changes in pressure within the waste discharge passage 12 and prevent gas from leaking into the room.

[0023] As shown in Figure 2, the toilet body 1 is provided with a rim connection port 13 and a flush connection port 14 that can communicate with the bowl body 11 (each with a spray nozzle). flow Vessel 7 and spray Shooting (The rim connection port 13 and the flush connection port 14 cannot be fully shown because the container 6 is attached.) In the embodiments of this disclosure, the rim connection port 13 is provided on the upper part of the bowl body 11, and the flush connection port 14 is provided on the lower part of the bowl body 11, corresponding to the position of the water seal area 110. In the embodiments of this disclosure, the water tank 10 may be integrated into the toilet body 1, and in other embodiments, the water tank 10 may be provided separately from the toilet body 1, but is not limited thereto.

[0024] As shown in Figure 1, the cleaning system may have one or more spray lines 20, and the outlet end of the spray line 20 is connected to the toilet body 1 to spray cleaning onto the water seal area 110 of the toilet body 1, thereby discharging waste by siphon action.

[0025] The cleaning system may further include a first water supply pipeline 21 and a second water supply pipeline 22, the outlet ends of both the first water supply pipeline 21 and the second water supply pipeline 22 being connected to the inlet end of the injection pipeline 20. The first water supply pipeline 21 is supplied with pressurized water to increase the impact force. Booster pump 3 A system will be established.

[0026] The cleaning system may further include a control valve 4, which is connected to a first water supply pipeline 21 and a second water supply pipeline 22, and controls the flow between the outlet ends of the first water supply pipeline 21 and the second water supply pipeline 22 and the inlet end of the injection pipeline 20.

[0027] The cleaning system may further include a control device 5, which is electrically connected to the control valve 4 and the booster pump 3, and may be configured to control the system to connect the outlet end of the first water supply pipe 21 and the inlet end of the injection pipe 20 in the first operating state, and to control the system to connect the outlet end of the second water supply pipe 22 and the inlet end of the injection pipe 20 in the second operating state. First operating state It is connected to the municipal power supply. Second operating state It is connected to a backup power supply.

[0028] In the embodiments of this disclosure, the control valve 4 employs an integrated design that can control the flow of multiple water lines, reducing the number of connecting parts, thereby reducing the complexity of connections and lowering costs. In one exemplary embodiment, the control valve 4 may be a plurality of independently designed control valve units, one of which controls the first water supply pipeline 21 and another control valve unit controls the second water supply pipeline 22.

[0029] In the embodiments of this disclosure, one or more spray lines 20 may be provided. If there is one spray line 20, both the first water supply line 21 and the second water supply line 22 may be connected to the spray line 20, and the provision of multiple connection ports in the toilet body 1 can be avoided by a single spray line 20. If there are two spray lines 20, the first water supply line 21 and the second water supply line 22 may each be connected to the corresponding spray line 20.

[0030] The cleaning system of the embodiment of this disclosure is designed with two cleaning systems that can not only clean the toilet body 1 with pressurized water when electricity is available, but also clean the toilet body 1 using the municipal water supply even in the event of a power outage.

[0031] Examples of the present disclosure Second water supply pipeline 22The water inlet is configured to connect to the municipal water supply pipeline (generally referring to the water supply pipeline), First water supply pipeline 21 The water inlet is configured to be connected to the water tank 10. Embodiments of this disclosure employ two independent water supply lines, the two independent water supply lines do not affect each other, and thus each of the two water supply lines can be operated independently.

[0032] As shown in Figure 1, the cleaning system may further include a rim pipe 23, the inlet end of which is configured to be connected to a second water supply pipe 22. The outlet end of the rim pipe 23 is configured to be connected to the toilet body 1 in order to generate a rim water flow to clean the toilet body 1. A control valve 4 may also be connected to the rim pipe 23, and can control the flow between the inlet end of the rim pipe 23 and the second water supply pipe 22.

[0033] As shown in Figures 4 to 6, the control valve 4 in the embodiment of this disclosure employs a mixed multiport valve, and the control valve 4 comprises a valve body 40, a first control mechanism 41, and a second control mechanism 42. The valve body 40 is provided with a communication passage 40a, a first flow path 401 and a second flow path 402 located upstream of the communication passage 40a, and a third flow path 403 and a fourth flow path 404 located downstream of the communication passage 40a.

[0034] The first control mechanism 41 is provided on the valve body 40 and controls the outlet end of the first flow path 401 and Communication passage 40a The system controls the connection between the inlet and outlet ends. The inlet end of the first channel 401 is configured to connect to the municipal water supply pipeline, the inlet end of the second channel 402 communicates with the outlet end of the first channel 401, and the outlet end of the second channel 402 is connected to the water tank 10, ensuring a continuous supply of water to the water tank 10.

[0035] Here, the communication port between the first channel 401 and the second channel 402 is normally open, thereby allowing for a continuous supply of water to the water tank 10. The first control mechanism 41 controls the connection between the first channel 401 and the communication passage 40a. When the first channel 401 and the communication passage 40a are connected, the water flows into the communication passage 40a and flows towards the second control mechanism 42 (see Figure 5).

[0036] The second control mechanism 42 is provided on the valve body 40 and can control the connection between the outlet end of the communication passage 40a and the inlet end of the third passage 403, and can control the connection between the outlet end of the fourth passage 404 and the inlet end of the third passage 403. The outlet end of the third passage 403 is connected to the inlet end of the injection pipe 20. The inlet end of the fourth passage 404 is connected to the outlet end of the first water supply pipe 21.

[0037] The valve body 40 is provided with a fifth channel 405 located downstream of the communication passage 40a, and the outlet end of the fifth channel 405 is connected to the rim pipe 23. The second control mechanism 42 further, Communication passage 40a The system is configured to control the flow between the outlet end of the first channel and the inlet end of the fifth channel 405. When the toilet device 100 is supplied with water, the water flows through the communication passage 40a to the second control mechanism 42, and the water flow is then distributed by the second control mechanism 42 and flows into the third channel 403 or the fifth channel 405 (see Figure 6).

[0038] In the first operating state (connected to the municipal power supply and with electricity), the control device 5 is configured to control the first control mechanism 41 to switch the disconnection between the outlet end of the first channel 401 and the inlet end of the communication passage 40a. The control device 5 is further configured to control the second control mechanism 42 to switch the connection between the outlet end of the fourth channel 404 and the inlet end of the third channel 403, and the second control mechanism 42 to control the connection between the outlet end of the fourth channel 404 and the inlet end of the fifth channel 405.

[0039] In the second operating state (using backup power, no electricity), the control device 5 is configured to control the first control mechanism 41 to switch the connection between the outlet end of the first flow path 401 and the inlet end of the communication passage 40a. The control device 5 is further configured to control the second control mechanism 42 to switch the connection between the outlet end of the communication passage 40a and the inlet end of the third flow path 403, and the second control mechanism 42 to control the connection between the outlet end of the communication passage 40a and the inlet end of the fifth flow path 405.

[0040] In the embodiments of this disclosure, both the first control mechanism 41 and the second control mechanism 42 may employ electrically controlled control mechanisms. The first control mechanism 41 is provided with a solenoid valve core 410 to achieve the opening and closing of the waterway, and the second control mechanism 42 is provided with a solenoid valve core 420 to achieve the switching of the waterway.

[0041] As shown in Figures 1 to 3, the cleaning system may further include a sprayer 6 provided at the outlet end of the spray pipe 20 and a jetter 7 provided at the end of the rim pipe 23. The sprayer 6 may be installed in combination with the cleaning connection port of the toilet body 1 to generate a water jet and discharge waste by siphon action. The nozzle of the jetter 7 may be installed corresponding to the wall surface of the bowl body 11 to generate a rim water jet to clean the toilet.

[0042] As shown in Figure 1, the cleaning system may further include a toilet cover cleaning pipe 24, the inlet end of which may be connected to the municipal water supply pipe, and the outlet end of which may be connected to the toilet cover 1a in order to clean the toilet cover 1a.

[0043] As shown in Figures 7 and 8, the control device 5 may be connected to a switching power supply, thereby supplying power to the booster pump 3 and the control valve 4. Alternatively, the control device 5 may be connected to an energy storage power supply 9, which can supply power to the control valve 4 in the event of a power outage. The switching power supply may refer to an AC power supply (for example, a municipal power supply).

[0044] The control device 5 in the embodiment of this disclosure may employ a PCBA electrical control board that can be installed inside the control box of the toilet unit 1. The PCBA electrical control board is provided with a power interface that can be connected to the municipal power supply and a power interface that can be connected to the energy storage power supply 9.

[0045] In the embodiments of this disclosure, the energy storage power source 9 may refer to a portable power source having a certain capacity, such as a backup power supply battery capable of storing electrical energy. For example, the energy storage power source 9 may be a supercapacitor energy storage power source and may be installed on the PCBA electrical control board (see Figure 7), and may supply power to the first control mechanism 41 and the second control mechanism 42. The control device 5 may further be configured to charge the energy storage power source 9 and store energy when connected to a switching power source (when there is electricity).

[0046] The cleaning system of the embodiment of this disclosure has two water supply lines 21 and 22, both capable of cleaning the toilet body 1. The first water supply line 21 is equipped with a pressure boosting pump 3 that can output a relatively high-pressure water flow to clean the toilet body 1, allowing cleaning to be performed under high water pressure conditions of the water supply line, as well as being unaffected by fluctuations in water pressure in the pipes when the water supply line is at low pressure. The second water supply line 22 can perform low-pressure cleaning in the event of a power outage.

[0047] Because the booster pump 3 has relatively high power, its startup needs to be controlled when the control device 5 is connected to the municipal power supply. In the event of a power outage, i.e., when the control device 5 is connected to the municipal power supply and cannot be supplied with power, the control device 5 needs to be connected to the energy storage power supply 9. This allows the energy storage power supply 9 to supply power to the control valve 4, controlling the second water supply pipeline 22 to start water supply and flush the toilet unit 1.

[0048] The operating current of the pressure booster pump 3 may be around 4000mA, and the operating voltage may be around 10V. It can operate continuously for 20 seconds, and the electrical energy consumed is approximately 4A*10*20=800kWh. The operating current of the stepping motor of the control valve 4 may be around 100mA, and the operating voltage may be around 6V. It can operate for a total of 2 seconds, and the electrical energy consumed is approximately 0.1A*6*2=1.2kWh. The stepping motor operates only during the function startup and function switching processes. After switching to a position, it waits for the function operation to complete before switching or resetting again. Pulse drive may be used for the stepping motor drive, with each pulse being around 100mA. This is more energy-efficient compared to devices requiring continuous output operation. Therefore, when not connected to the municipal power supply (power outage), the energy storage power supply 9 supplies power only to the control valve 4, resulting in low energy consumption.

[0049] The power supply circuits for the pressure boosting pump 3 and the control valve 4 in the embodiment of this disclosure may be designed independently, and a power interface separately provided in the control device 5 can be connected to an energy storage power supply 9. The energy storage power supply 9 supplies power to the control valve 4 independently, thereby reducing the power consumption of the energy storage power supply 9, and the energy storage power supply 9 can be reused multiple times, thereby reducing costs.

[0050] The cleaning system in the embodiment of this disclosure is designed with two water supply lines 21 and 22, allowing for high-pressure cleaning of the toilet unit 1 when electricity is available, as well as low-pressure cleaning of the toilet unit 1 even during a power outage. Furthermore, the cleaning system according to the embodiment of this disclosure is connected to an energy storage power source 9 and can independently supply power to the second water supply line 22 to achieve low-pressure drive control. This results in low energy consumption of the energy storage power source 9, allowing for multiple reuses and lower costs.

[0051] Figure 7As shown, the cleaning system according to the embodiment of the present disclosure introduces the municipal water supply pipeline (water source) by providing an angle valve 81, and then connects to a three-way connecting pipe 82 by the pipeline. The three-way connecting pipe 82 divides the water supply into two channels, one of which passes through a control valve 4 and enters the water tank 10, and the water that enters the water tank 10 1st water supply pipe 21 The water passes through to the control valve 4, then through the control valve 4 to enter the injection line 20, which flushes the toilet body 1. The other waterway passes through the second water supply line 22 to the control valve 4, then through the control valve 4 to enter the injection line 20, which flushes the toilet body 1, or enters the rim line 23 to flush the rim of the toilet body 1 (see Figure 3).

[0052] When the flushing system is in operation with electricity (municipal power), the control device 5 (e.g., PCBA electrical control board) is connected to the power supply (municipal power). Upon receiving a flushing command, the control device 5 controls the booster pump 3 (flushing pump) to operate and controls the control valve 4 to connect the first water supply pipe 21 and the spray pipe 20, thereby flushing the toilet body 1. The control device 5 further controls the control valve 4 to connect the second water supply pipe 22 and the rim pipe 23, enabling rim flushing of the smart toilet 1. At this time, the toilet cover flushing pipe 24 (smart toilet cover waterway shown in Figure 7) is connected, and the toilet cover is flushed.

[0053] If the flushing system is in a state of power outage (municipal power outage), the control device 5 is connected to an energy storage power source 9 (e.g., a backup power supply battery), the energy storage power source 9 supplies power to the control valve 4, and upon receiving a flushing command, the control device 5 controls the control valve 4 to connect the second water supply pipeline 22 and the injection pipeline 20 to flush the smart toilet 1, and the control device 5 further connects the second water supply pipeline 22 and Rim conduit 23 The control valve 4 is controlled to connect the two, allowing the smart toilet 1 to be rim-cleaned. At this time, the toilet cover cleaning pipeline 24 is disconnected, and the toilet cover is not cleaned. In Figure 8, "X" in the pipeline indicates that the waterway is closed, and " / " indicates that the function is unavailable.

[0054] The backup power supply implemented in this disclosure supplies power only to the control valve 4, resulting in slow battery consumption and the ability to be reused multiple times, thereby reducing costs and avoiding large amounts of energy waste and environmental pollution.
