[0024] This application provides an exemplary toilet, such as... Figure 2 As shown, the toilet includes a control unit 200, a toilet body 100, and a brush ring system for the toilet brush ring. The toilet body includes a toilet bowl, and the brush ring system includes a brush ring nozzle device 1 with a brush ring water outlet 14, a foam liquid supply device 3 for supplying foam liquid, and a brush ring water supply device 8 for supplying brush ring water. The brush ring nozzle device 1 is connected downstream of the foam liquid supply device 3 and the brush ring water supply device 8.

[0025] exist Figure 2In the example, the brush ring water supply device 8 may include a water tank and a first water passage 5 connected to the water tank. A water pump or a control switch may be installed on the first water passage 5. Of course, the first water passage 5 may also be directly connected to the municipal water supply pipe. The brush ring water control device 8 controls the water pump or control switch through the control unit 200 to control the opening and closing of the brush ring water supply device 8. The foam liquid supply device 3 is provided with a third water passage 7, and a water pump may be installed on the third water passage 7. The control unit 200 controls the water pump to realize the opening and closing of the foam liquid supply device 3.

[0026] In one embodiment, the structure of the brush ring nozzle device 1 is as follows: Figure 6 and Figure 7 As shown, the brush ring nozzle device 1 has a brush ring water inlet 11 connected to the first water channel 5, an aerated water inlet 12 connected to the second water channel 6, a foam liquid inlet 13 connected to the third water channel 7, and a brush ring water outlet 14 for water discharge. The brush ring nozzle device 1 internally has an inlet channel 16, an acceleration channel 17, and an outlet channel 18 sequentially formed along the water discharge direction. The brush ring nozzle device 1 can also have an air intake hole 15 at the acceleration channel 17. When the brush ring foaming function is activated, as... Figure 7 As shown, the brush ring water enters from the brush ring water inlet 11 and reaches the acceleration channel 17. It then sprays out from the acceleration channel 17 and enters the outlet channel 18. Due to the reduced flow area of ​​the acceleration channel 17, according to the Venturi effect, the brush ring water sprayed from the acceleration channel 17 creates a certain negative pressure in a small surrounding area, causing air to be drawn into the brush ring nozzle device 1 through the air intake 15, thus mixing with the water. The foam liquid provided by the foam liquid supply device 3 enters the brush ring nozzle device 1 through the foam liquid inlet 13, and the bubble water generated by the bubble water generating device 2 enters the brush ring nozzle device 1 through the bubble water inlet 12. The foam liquid and the air entering from the air intake 15 mix with the water at the acceleration channel 17 to generate foam. The foam water and the bubble water are mixed together and discharged from the brush ring water outlet 14 through the outlet channel 18. In this embodiment, the bubble water inlet 12 is located downstream of the foam liquid inlet 13 along the water outlet direction. In other embodiments, the bubble water inlet 12 can also be located upstream of the foam liquid inlet 13 along the water outlet direction.

[0027] Figure 6 and Figure 7In the example, the brush ring nozzle device 1 includes a connector 101, an air intake cover 102, a brush ring nozzle body 103, a nozzle 104, a pressure cap 105, a locking nut 106, and a sealing washer 107. The connector 101 is provided with a brush ring water inlet 11, an aerated water inlet 12, a foam liquid inlet 13, a water inlet channel 16, and an acceleration channel 17. The brush ring nozzle body 103 is provided with a water outlet channel 18. Alternatively, the acceleration channel 17 can be located within the brush ring nozzle body 103. Of course, the brush ring nozzle device 1 can also have other structural variations. The connector 101 is connected to the water inlet end of the brush ring nozzle body 103, the nozzle 104 is located at the water outlet end of the brush ring nozzle body 103, and the pressure cap 105 is threaded onto the brush ring nozzle body 103, thereby pressing the nozzle 104 tightly onto the brush ring nozzle body 103. When installing the brush nozzle device 1 onto the ceramic toilet body 100, firstly, the brush nozzle body 103 is passed through the mounting hole provided on the toilet body 100. A stop portion of the brush nozzle body 103 on one side of the toilet body 100 abuts against the toilet body 100, and the other side is locked by a locking nut 106. A flexible sealing washer 107 can be provided between the locking nut 106 and the toilet body 100. Then, the connector 101 is connected to the water inlet end of the brush nozzle body 103 by a snap-fit. Furthermore, an air intake cover 102 with an air intake hole 15 is installed on the connector 101, and the air intake cover 102 can be connected to the connector 101 by a snap-fit. An air intake chamber is formed between the air intake cover 102 and the connector 101. Gas entering the air intake chamber from the air intake hole 15 is drawn into the acceleration channel 17 through the air outlet 19, causing the gas to mix with the brush nozzle water.

[0028] Furthermore, to ensure that the foam liquid entering from the foam liquid inlet 13 can mix more evenly with water / air, the gap between the brush ring nozzle body 103 and the connector 101 can be shaped to allow for more uniform diffusion of the foam liquid, thereby improving the foaming efficiency of the foam liquid. Specifically, a chamfer can be provided on the outer side of the inlet end of the brush ring nozzle body 103, forming a small triangular cavity between the chamfer and the connector 101. After the foam liquid enters from the foam liquid inlet 13, it will first fill this triangular cavity. The triangular cavity can be connected to the internal water outlet channel 18 through multiple openings, so that the foam liquid entering the triangular cavity can be mixed into the brush ring water from different directions through multiple openings, thereby achieving faster mixing and foam generation.

[0029] In one embodiment, the brush ring system further includes a bubble water generating device 2 for generating bubble water, and the brush ring nozzle device 1 is connected to the bubble water generating device 2. Figure 8 and Figure 9A bubble water generating device 2 is disclosed in one embodiment. The bubble water generating device 2 is provided with an inlet 21, an outlet 22, and a water outlet channel connecting the inlet 21 and the outlet 22. The water outlet channel includes an expansion section 24, a contraction section 25, and an outlet section 26 arranged sequentially along the water flow direction. The cross-sectional area of ​​the expansion section 24 increases along the water flow direction, the cross-sectional area of ​​the contraction section 25 decreases along the water flow direction, and the cross-sectional area of ​​the inlet end of the contraction section 25 is not greater than the cross-sectional area of ​​the outlet end of the expansion section 24. The cross-sectional area of ​​the outlet section 26 is greater than the cross-sectional area of ​​the outlet end of the contraction section 25. The water outlet channel may also include an inlet section 23 located at the front end of the expansion section 24.

[0030] The water flows sequentially through the inlet section 23, the expansion section 24, the contraction section 25, and the outlet section 26, which causes the water flow velocity to change in a slow-accelerate-slow-down trend. This reduces and releases air from the water, increases the content of microbubbles or ultra-microbubbles in the water, and allows the huge pressure generated by the bursting of bubbles to produce ultrasonic vibrations, which can quickly remove dirt and improve the cleaning power of the water flow on exposed parts and ceramic structures. At the same time, it has the advantages of saving water, time and labor, thereby reducing the frequency of manual washing and improving the user experience.

[0031] In one example, the expansion section 24 may include a first expansion section 241 and a second expansion section 242 arranged sequentially along the water outlet direction. Both the first expansion section 241 and the second expansion section 242 are flow channels with gradually expanding cross-sections along the water outlet direction. The cross-sectional area of ​​the first expansion section 241 is smaller than that of the second expansion section 242. The water flow process expands twice through the first expansion section 241 and the second expansion section 242, and the flow velocity of the water is reduced twice, which can increase the degree of water flow dispersion and turbulence and increase the trend of water flow pattern change.

[0032] In one example, the contraction section 25 may include a main contraction section 251 and a squeezing section 252 at the outlet end of the main contraction section 251. The wall of the main contraction section 251 is arc-shaped to reduce energy loss of the water flow from the second expansion section 242 to the squeezing section 252. The wall of the main contraction section 251 may be provided with several guide ribs, which increase the flow velocity and rotation speed of the water flow. These guide ribs are uniformly arranged in a circumferential array on the wall of the main contraction section 251. Additionally, several diversion ribs may be provided within the squeezing section 252, dividing the channel within the squeezing section 252 into several diversion channels. When the water flows from the expansion section 24 into the main contraction section 251, the water flow re-converges, and the flow velocity increases. Before the diversion ribs, the flow cross-section contracts again, the flow pattern changes drastically, and the flow velocity increases further. At the same time, the water flow is accompanied by chaotic rotational motion, violently colliding in the area in front of the diversion ribs, releasing dissolved oxygen in the water. Then, as the water flows through the diversion ribs, it is squeezed and sheared, forming a vortex behind the diversion ribs. The flow cross-section of the outlet section 26 at the rear end expands, and the volume of air bubbles in the water is further reduced. Finally, the treated water containing ultrafine air bubbles is discharged through the outlet section 26.

[0033] It should be noted that the structure of the brush ring nozzle device 1 and the structure of the bubble water generating device 2 are not limited to the above and can be modified in various ways.

[0034] like Figure 2 As shown, the control unit 200 typically communicates and exchanges signals with the brush ring water supply device 8, the foam liquid supply device 3, and the aerated water generating device 2 via a communication bus. The control unit 200 includes at least one processor and a memory. The memory stores an executable toilet control program, which, when executed by the processor, implements a toilet flushing control method applied to the aforementioned toilet.

[0035] like Figure 1 As shown, the toilet flushing control method includes: performing the following steps in response to a self-cleaning command: The brush ring water supply device 8 and the foam liquid supply device 3 are activated for a first predetermined time to supply brush ring water and foam liquid to the brush ring nozzle device 1. The foam liquid is sprayed onto the toilet bowl surface through the brush ring nozzle device 1, and the foam reaches a predetermined position above the water surface.

[0036] In the technical solution provided in this application, during the self-cleaning process of the toilet, foam water is discharged from the brush ring outlet 14 of the brush ring nozzle device 1 to rinse the ceramic pot surface, thereby achieving a cleaning and sterilization effect. As the brush ring nozzle device 1 sprays foam water for a first predetermined time, the foam thickness continuously accumulates to a certain height on the pot surface. This height can be set so that the foam can cover most of the ceramic pot surface (the length of the first predetermined time can be set according to the height of the ceramic pot surface to be covered by the foam). The ceramic surface can be sterilized / disinfected under the covering and contact action of the foam. Therefore, in the solution provided in this application, the self-cleaning function of the toilet can be achieved using the brush ring nozzle device 1.

[0037] The steps in response to the self-cleaning command also include: controlling the bubble water generating device 2 to turn on in order to provide bubble water to the brush ring nozzle device 1.

[0038] During the process of controlling the water supply device 8 and the foam liquid supply device 3 to be turned on for a first predetermined time, the bubble water generating device 2 can be turned on so that the bubble water and foam water are discharged together from the water outlet 14 of the brush ring nozzle device 1 to rinse the ceramic pot surface, thereby playing a cleaning and sterilizing role.

[0039] exist Figure 2 In the example, the bubble water generating device 2 is provided with a second water channel 6, and a control switch can be installed on the second water channel 6. The control unit 200 controls the opening and closing of the bubble water generating device 2 through the control switch.

[0040] In one embodiment, after the step of controlling the brush ring water supply device 8 and the foam liquid supply device 3 to start for a first predetermined duration, the following steps are also performed in response to the self-cleaning command: Keep the foam on the toilet bowl surface for the second predetermined time; After the foam has been left to stand on the toilet bowl for a second predetermined period of time, the brush water supply device 8 and / or the bubble water generating device 3 are activated to flush the toilet and remove the foamy water from the toilet bowl.

[0041] In one embodiment, the first predetermined duration is 40-50 seconds; the second predetermined duration is 60-180 seconds.

[0042] For example, in one example, the first predetermined duration is 45 seconds, the second predetermined duration is 120 seconds, and when the brush nozzle device 1 sprays foam water onto the toilet bowl surface for 45 seconds, as... Figure 3As shown, the foamy water rises from the water surface to a height of H1, and the height of the water surface is H2. Therefore, the height the foamy water reaches on the pot surface is H1 + H2. The first predetermined time can be set according to the desired height of the pot surface reached by the foamy water. This height is usually lower than the lower edge of the brush ring spray nozzle 14 to prevent foamy water from splashing outside the toilet bowl. After the foamy water remains still inside the pot surface for 120 seconds or other durations, the toilet is flushed to expel the foamy water from the drain pipe.

[0043] In one example, such as Figure 3 As shown, after the brush ring water supply device 8 and the foam liquid supply device 3 are turned on for a first predetermined time, the foam reaches the predetermined position above the water surface as follows: the distance H1 between the highest point of the foam and the water surface is greater than the distance H3 between the highest point of the foam and the brush ring water outlet 14.

[0044] In one example, such as Figure 4 and Figure 5 As shown, the toilet bowl includes a water-guiding curved surface 110 for guiding the water flow of the brush ring and a waste-receiving surface 120 below the water-guiding curved surface 110. The water-guiding curved surface 110 is connected to the waste-receiving surface 120 by an arc surface 130 with a curvature greater than that of the waste-receiving surface. Foam covers the waste-receiving surface 120 or at least a portion of the water-guiding curved surface 110.

[0045] In one embodiment, the control method further includes: responding to a pre-wetting command, controlling the brush ring water supply device 8 to operate for a third predetermined duration, during which time the brush ring nozzle device 1 sprays water to wet the pot surface; or controlling the brush ring water supply device 8 and the foam liquid supply device 3 to operate for a third predetermined duration, during which time the brush ring nozzle device 1 sprays foam water to wet the pot surface, and the sprayed foam water can play a splash-proof role when the user uses the toilet. Since wetting only requires the brush ring nozzle device 1 to spray a very small amount of water onto the pot surface, the third predetermined duration can be set to be shorter than the first predetermined duration.

[0046] The pre-wetting instruction can be information provided to the toilet by the user who is about to use the toilet. For example, information such as the user sitting on the toilet seat, the user opening the toilet lid, the user walking to the toilet, or the user pressing the wetting control button can be obtained. By wetting the toilet before the user uses the toilet, it is possible to prevent the waste from sticking to the toilet surface, thus making the toilet easier to flush.

[0047] In one embodiment, the control method further includes: in response to a brush ring command, controlling the brush ring water supply device 8 to operate for a fourth predetermined duration; or, in response to a brush ring command, controlling the brush ring water supply device 8 and the foam liquid supply device 3 to operate for a fourth predetermined duration, during which time the brush ring nozzle device 1 sprays foamed brush ring water to rinse the pot surface. The fourth predetermined duration is shorter than the first predetermined duration.

[0048] In one example, during the toilet's self-cleaning process, the brush nozzle device 1 sprays foam water onto the toilet bowl surface for a first predetermined duration of 40-50 seconds; in response to a pre-wetting command, the brush nozzle device 1 sprays water onto the toilet bowl surface for a third predetermined duration of 2-5 seconds; and in response to a brush command, the brush nozzle device 1 sprays water onto the toilet bowl surface for a fourth predetermined duration of 5-10 seconds. Of course, the duration is not limited to these and can be adjusted according to specific circumstances.

[0049] In one embodiment, the toilet also includes a self-cleaning component and a movable spray nozzle 42 for washing the human body, such as Figure 1 As shown, in response to the self-cleaning command, the following steps are also performed: controlling the self-cleaning component to clean the spray bar 42.

[0050] In one embodiment, the self-cleaning component includes a water spraying mechanism 43, which is configured to spray water onto the spray bar 42. Controlling the self-cleaning component to clean the spray bar 42 includes controlling the spray bar 42 to move, and controlling the water spraying mechanism 43 to spray cleaning water onto the spray bar 42 during the movement of the spray bar 42.

[0051] like Figure 10 and Figure 11 A cleaning device 4 is provided in one embodiment. The cleaning device 4 includes a base 41 and a spray bar 42 that is reciprocating and movable on the base 41. A water spraying mechanism 43 is provided on the base 41 to spray water onto the spray bar 42.

[0052] Figure 12 and Figure 13 A structure of a water spraying mechanism 43 in one embodiment is provided. In this embodiment, the water spraying mechanism 43 has a water inlet connector 431 for connecting to a water supply pipeline. The water spraying mechanism 43 has a water inlet channel 433, an acceleration channel 434, and a mixing channel 435 connected sequentially along the water outlet direction. The mixing channel 435 is provided with a plurality of water outlets 436, each water outlet 436 being located above the spray bar 42 and facing the surface of the spray bar 42. The mixing channel 435 is also connected to a liquid storage chamber 438. The flow area of ​​the acceleration channel 434 is smaller than the flow area of ​​the water inlet channel 433 and the mixing channel 435, and the mixing channel 435 is provided with an air inlet 437 connected to the external environment. The water flow accelerates as it passes through the acceleration channel 434. Based on the Venturi principle, this creates negative pressure in the mixing channel 435, drawing in outside air and cleaning liquid from the storage chamber 438 to mix with the water flow and form mixed cleaning water. The cleaning power of the cleaning liquid and the flushing force generated by the bursting of bubbles clean the spray bar 42, improving the cleaning effect on stubborn dirt and bacteria with strong adhesion.

[0053] In this embodiment, the liquid storage chamber 438 has an opening 432 communicating with the external environment. When there is cleaning liquid in the liquid storage chamber 438, the water outlet 436 sprays out foam water mixed with cleaning liquid. When there is no cleaning liquid in the liquid storage chamber 438, the water outlet 436 sprays out foamed cleaning water, that is, water containing no cleaning liquid but only mixed with air. Multiple water outlets meet the diverse usage needs of users.

[0054] In one embodiment, the toilet may also be equipped with a heating device 9, which is configured to heat water. The heated water is supplied to the spray mechanism 43 and the bubble water generating device 2 through a two-way valve 10. That is, the spray mechanism 43 can clean the spray bar 42 with hot water, and the bubble water generating device 2 uses hot water to generate bubble water. Hot water helps to improve the cleaning effect.

[0055] In one embodiment, during the process of the water spraying mechanism 43 spraying water to clean the spray bar 42, the movement of the spray bar 42 is controlled. Controlling the movement of the spray bar 42 may include: controlling the spray bar 42 to reciprocate between a first predetermined position and a second predetermined position; and / or, controlling the spray bar 42 to stay at at least one predetermined position in the movement path for a predetermined time.

[0056] In one example, the control boom 42 reciprocates between a first predetermined position and a second predetermined position. The first predetermined position is the starting position of the boom 42 when the base 41 is in a retracted state, and the second predetermined position is the ending position of the boom 42 when it extends from the base 41 to the working state. That is, the boom 42 moves to its maximum range. In this way, during the movement of the boom 42, the water spraying mechanism 43 can spray water to clean the boom 42 over a large range.

[0057] In another example, the control boom 42 reciprocates between a first predetermined position and a second predetermined position, both of which are positions between a starting position and an ending position of the boom 42. The area between the first and second predetermined positions can be a key area of ​​the boom 42 that is prone to getting dirty. Thus, during the movement of the boom 42, the water spray mechanism 43 can clean the key areas of the boom 42 that are prone to getting dirty.

[0058] In another example, controlling the movement of the spray bar 42 includes controlling the spray bar 42 to remain at at least one predetermined position in the movement path for a predetermined time. This predetermined position can be a location on the spray bar 42 that is prone to getting dirty. Therefore, controlling the spray bar 42 to remain at at least one predetermined position for a predetermined time during the water spraying process by the water spraying mechanism 43 can improve the cleaning effect on stubborn dirt and bacteria with strong adhesion. The number of predetermined positions, their locations, and the dwell time can be preset according to actual application requirements.

[0059] In another example, controlling the movement of the spray bar 42 includes: controlling the spray bar 42 to reciprocate between a first predetermined position and a second predetermined position; and controlling the spray bar 42 to remain at at least one predetermined position in the movement path for a predetermined time. That is, the spray bar 42 can be controlled to move back and forth within a certain range, causing the water spraying mechanism 43 to spray water to clean that range. Furthermore, for locations on the spray bar 42 that are dirty, the spray bar 42 can remain at the location corresponding to the dirt on the water spraying mechanism 43 for a certain time, allowing the water spraying mechanism 43 to effectively clean the dirty location.

[0060] In one embodiment, such as Figure 10 and Figure 11 As shown, the self-cleaning component may also include a sterilization lamp 44, and controlling the self-cleaning component to clean the spray bar 42 further includes: turning on the sterilization lamp 44 to sterilize the surface of the spray bar 42 by means of the sterilization lamp 44.
