[0001] The present application relates to the field of bathroom technology, and in particular to a flushing control method of a smart toilet. BACKGROUND

[0002] In the design of existing smart toilets, the toilet needs to be washed and flushed. During washing, a washing pump is used for control to wash the wall surface of the toilet. During flushing, a down-pumping pump is used for control to achieve the purpose of flushing away dirt. Since multiple pumps are used for control, a large space is required, and the control is complex.

[0003] In order to overcome the above problems, the patent for invention with publication number CN115262714A discloses an integrated water device with a double-outlet micro pump, which includes a shell, a drainage mechanism, a double-outlet micro pump and a drainage base. The water source is divided into two paths by the double-outlet micro pump, and is used for drainage and washing respectively. Through integrated design, the structure is simple and can be used for small-space submerged smart toilets without water tanks. However, the structure cannot realize the function of separate washing.

[0004] With the increasing functions of smart toilets, such as washing, water replenishment, wall moistening, drainage and other functions, and the increasing application scenarios of water pumps, in order to meet different use requirements, when washing, water replenishment and wall moistening functions are performed, it is required that the water flow only flows out from the washing port. The existing toilet cannot realize the requirement of separate water outflow by using only one water pump, and multiple water pumps need to be set to realize the requirement. However, the smart toilet has the requirements of miniaturization and aesthetic design, and the structure of multiple water pumps increases the volume of the water tank, which greatly limits the design of the toilet. SUMMARY

The drainage channel is a drainage port in the water tank which is driven to open or close by a drainage mechanism. The motor of the water pump can rotate in a first direction or a second direction. The flushing control method includes the following processes:

[0007] b. controlling the motor to rotate in the second direction, so that the water pump drives water flow into the washing channel to wash or supplement water or wall of the upper part of the toilet bowl; or controlling the motor to rotate in the first direction, so that the water pump drives water flow into the drainage channel and the washing channel at the same time, to flush the bottom of the toilet bowl, and to flush the upper part of the toilet bowl at the same time; when the first direction is clockwise, the second direction is counterclockwise; when the first direction is counterclockwise, the second direction is clockwise.

[0008] The application further discloses another flushing control method of an intelligent toilet, wherein the intelligent toilet is provided with a water pump, a drainage mechanism and a drainage base, the water pump is provided with a plurality of water outlets, the intelligent toilet is provided with a washing pipeline or provided with a washing pipeline and an auxiliary flushing pipeline at the same time, a water pump motor can rotate in a first direction or a second direction, and the flushing control method comprises the following processes:

DETAILED DESCRIPTION

[0058] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below with reference to the drawings and examples.

[0059] Example 1

[0060] The present application discloses a flushing control method of an intelligent toilet. The intelligent toilet is provided with a water pump, a washing channel and a drain channel. The drain channel is a drain port in the water tank which is driven to open or close by a drain mechanism. Similarly, the washing channel can be a separately provided washing pipe or an internal channel formed by a communication hole provided on the ceramic toilet body.

[0061] The water pump motor can rotate in a first direction or a second direction. The flushing control of the intelligent toilet has the following two processes:

[0062] 1. The water pump drives the water flow into the washing channel alone to wash or replenish water or moisten the wall of the upper part of the toilet bowl.

[0063] 2. The water pump drives the water flow into the washing channel and the drainage channel at the same time to flush the bottom of the toilet bowl and to flush the upper part of the toilet bowl at the same time. When the toilet flushes from the bottom of the bowl, some sewage or dirt will splash onto the wall of the toilet bowl, so the upper part of the bowl is flushed at the same time, and the flushing water can flush the splashed sewage or dirt away from the bowl, making the toilet wall clean.

[0064] The specific control method includes the following steps:

[0065] a. Receive the start instruction and the program control instruction, and obtain the corresponding water pump motor rotation direction instruction according to the program control instruction; and transmit the rotation direction instruction to the water pump motor.

[0066] The program control instruction includes one or more single-step instructions or composite instructions listed in Table 1.

[0067] Table 1. Relationship table of program control instruction and rotation direction instruction

[0068] When the first direction is clockwise (water pump motor forward), the second direction is counterclockwise (water pump motor reverse); when the first direction is counterclockwise, the second direction is clockwise.

[0069] The replenishing water method of the intelligent toilet has two kinds, one is to replenish water through the water flow into the washing channel, and the other is to replenish water through the water inlet valve. In other embodiments, water can also be replenished through the water inlet valve.

[0070] b. The water pump motor controls according to the rotation direction instruction: controls the motor to rotate in the second direction, so that the water pump drives the water flow into the washing channel to wash or replenish water or moisten the wall of the upper part of the toilet bowl; or controls the motor to rotate in the first direction, so that the water pump drives the water flow into the washing channel and the drainage channel at the same time to flush the bottom of the toilet bowl and to flush the upper part of the toilet bowl at the same time.

[0071] Embodiment two

[0072] The application discloses a flushing control method of an intelligent toilet. The intelligent toilet is provided with a water pump, a washing channel, a drainage channel and a rib flushing channel.

[0073] The drain channel is a drain opening in the water tank driven to open or close by the drain mechanism. Similarly, the washing channel can be a separate washing pipe or an internal channel formed by a communication hole provided on the ceramic toilet body. The flushing channel can be a separate flushing pipe or an internal channel formed by a communication hole provided on the ceramic toilet body.

[0074] The water pump motor can rotate in a first direction or a second direction. The flushing control of the intelligent toilet has the following two processes:

[0075] 1. The water pump drives the water flow to enter the washing channel alone, and washes or replenishes water or moisturizes the upper part of the toilet bowl cavity.

[0076] 2. The water pump drives the water flow to enter the drain channel, washing channel and flushing channel at the same time, and assists flushing at the bottom of the toilet bowl cavity, while flushing the upper part of the toilet bowl cavity. When the toilet flushes from the bottom of the bowl, some sewage or dirt will splash onto the wall of the toilet bowl cavity, so the upper part of the toilet bowl cavity is flushed at the same time, and the flushing water can flush the splashed sewage or dirt from the toilet bowl, making the toilet wall clean. The flushing channel is connected to the drain channel at the end, and the setting of the flushing channel can improve the jetting force during flushing, effectively improving the flushing and sewage discharge capacity of the toilet.

[0077] The specific control method includes the following steps:

[0078] a. Receive start instruction and program control instruction, get corresponding water pump motor direction instruction according to program control instruction; transmit the direction instruction to the motor of the water pump.

[0079] The program control instruction includes one or more single-step instructions or composite instructions listed in Table 2.

[0080] Table 2. Relationship table of program control instruction and direction instruction

[0081] When the first direction is clockwise (water pump motor forward), the second direction is counterclockwise (water pump motor reverse); when the first direction is counterclockwise, the second direction is clockwise. There are two ways to replenish water for the intelligent toilet, one is to replenish water through the water flow entering the washing channel, and the other is to replenish water through the water inlet valve. In other embodiments, water can also be replenished through the water inlet valve.

[0082] b. The water pump motor controls the water pump according to the steering instruction: controls the motor to rotate in the second direction, so that the water pump drives the water flow into the washing channel to wash or supplement water or wet the upper part of the toilet bowl; or controls the motor to rotate in the first direction, so that the water pump drives the water flow into the drainage channel, the washing channel and the flushing assisting channel at the same time, to assist flushing the bottom of the toilet bowl, and at the same time, to flush the upper part of the toilet bowl.

The rotor 21 of the motor 2 is fixedly connected with the impeller 3, and the motor shaft 22 is connected with the assembly hole 112 of the connecting frame 111. The cross section of the assembly hole 112 connected with the motor shaft 22 is in D shape, which can prevent the motor shaft 22 from rotating axially in the assembly hole 112. The impeller 3 is arranged in the pump cavity 14, and the impeller 3 comprises a first connecting plate 31, a second connecting plate 32 and a plurality of blades 33 evenly arranged between the first connecting plate 31 and the second connecting plate 32. As shown in FIG. 9, the first connecting plate 31 is provided with an opening 34 in the middle, and the diameter of the opening 34 is larger than that of the water inlet 15. The opening 34 is provided with an arc-shaped guide surface 35 at the end for guiding water flow. The water flow can enter the impeller 3 through the opening 34 after entering the water inlet 15, and the water flow is guided to the first water outlet channel 16, the second water outlet channel 17 and the third water outlet channel 18 by the rotation of the impeller 3.

[0092] As shown in FIG. 12, the motor 2 is a reversible motor, and the motor 2 drives the impeller 3 to rotate in a first direction or a second direction. The first direction is the clockwise direction as shown by W1 in FIG. 12, and the second direction is the counterclockwise direction as shown by W2 in FIG. 13. In other embodiments, the first direction can also be the counterclockwise direction, and the second direction is the clockwise direction.

[0093] The first water outlet channel 16 is connected to the drainage mechanism 92. When the first water outlet channel 16 is used to discharge water, the drainage mechanism 92 of the water pump 1 is driven by the water pressure, and the piston in the drainage mechanism 92 moves upward, thereby opening the water sealing rubber 921 below the drainage mechanism 92, i.e. opening the water inlet of the drainage base 93, so that the water source can flow out of the drainage base 93, and the drainage base is connected to the drain outlet 812 through a drainage elbow 51, so that the water flows into the drain outlet 812 to realize flushing, as shown in FIG. 21. The second water outlet channel 17 is connected to the outside of the shell 91 to be connected to the external washing pipeline 6, and the other end of the washing pipeline 6 is connected to the washing hole 811 to discharge water through the washing hole 811 to realize water replenishment or wall wetting or washing of the upper wall of the toilet bowl.

The other end of the inverted U-shaped pipe 942 is connected to one end of the flushing pipe 943, and the other end of the flushing pipe 943 is connected to the outlet of the drainage base 93. The inverted U-shaped pipe 942 is provided with an anti-siphon hole 944, which is located higher than the working water level in the water tank to reduce the influence of negative pressure in the pipeline and prevent siphon. The flushing pipe 943 is inserted into the drainage base 93 and penetrates the water outlet of the drainage base 93. The flushing pipe 943 can be assembled separately from the drainage base 93, or the flushing pipe 943 and the drainage base 93 can be integrally formed. The diameter of the flushing pipe 943 gradually decreases to increase the flow rate of the fluid at the outlet position.

[0095] As shown in FIG. 7, the third water outlet channel 18 includes a cylindrical inner pipe body 182, and an outer pipe body 183 coaxially connected to the end of the inner pipe body 182. The outer pipe body 183 is provided with two stroke grooves, including a vertical groove section 184 and a rotating groove section 185 connected to the vertical groove section.

[0096] The principle of the water outlet is that when the impeller 3 rotates in a certain direction, the water flow is easy to flow out along the tangent direction, and it is not easy to flow out against the tangent direction. The tangent direction along which the water outlet opening is arranged is parallel to the tangent direction of the corresponding pump cavity outer edge (along the current rotation direction), or is arranged at a small angle a with the tangent direction. The tangent direction against which the water outlet opening is arranged is parallel to the tangent direction of the corresponding pump cavity outer edge (against the current rotation direction), or is arranged at a small angle a with the tangent direction. When the water outlet opening is arranged at a large angle β with the tangent direction of the corresponding pump cavity outer edge, the angle β > a, the water flow can flow out from the current outlet no matter the first direction rotation or the second direction rotation. The angle defined in this application is an angle less than 90 degrees, in order to meet the corresponding flow requirements, the angle a ≤ 30°, and the angle β > 30°; more preferably, the angle a ≤ 10°, and the angle β > 45°.

For the design requirement of miniaturization, generally only one first water outlet 161 needs to be arranged in the first water outlet channel 16. In some embodiments, the first water outlet channel 16 is also provided with other water outlets, the flow of the other water outlets is extremely small, and does not affect the realization of the effect of this application. The second water outlet channel 17 is provided with one or more second water outlets 171, so that at least one second water outlet 171 flows out when the impeller rotates in the first direction or in the second direction, and the second water outlet channel 17 is connected to the outside of the shell. The third water outlet channel 18 includes a third water outlet 181, the opening of the third water outlet 181 is arranged at an angle a with the tangent direction of the corresponding pump cavity outer edge, or is parallel to the tangent direction; and the direction of the third water outlet 161 is along the water flow direction when the impeller 3 rotates in the first direction. For the design requirement of miniaturization, generally only one third water outlet 181 needs to be arranged in the third water outlet channel 18. In some embodiments, the third water outlet channel 18 is also provided with other water outlets, the flow of the other water outlets is extremely small, and does not affect the realization of the effect of this application.

The first water outlet 161 corresponds to the point P1 on the outer edge of the pump cavity, and the tangent line along P1 (in the direction of W1) is the setting direction of the first water outlet 161. The third water outlet 181 corresponds to the point P4 on the outer edge of the pump cavity, and the tangent line along P4 (in the direction of W1) is the setting direction of the third water outlet 181.

[0099] The two second water outlets 171 of the second water outlet channel 17 are generally provided in the following three implementation cases:

[0100] (1) As shown in FIG. 14a, the second water outlet channel includes a second water outlet A and a second water outlet B; the second water outlet A 1711 and the second water outlet B 1712. The opening direction of the second water outlet A 1711 is set at an angle β with the tangent direction of the corresponding outer edge of the pump cavity. In the figure, the point P2 on the outer edge of the pump cavity corresponding to the second water outlet A 1711 is tangent to the tangent line q1, and the opening direction of the second water outlet A 1711 is at an angle β1=52° with the tangent line q1. The opening direction of the second water outlet B 1712 is parallel to the tangent direction of the corresponding outer edge of the pump cavity, or is set at an angle α with the tangent direction, and the direction of the second water outlet B 1712 is along the water flow direction of the impeller 3 rotating in the second direction. In the figure, the point P3 on the outer edge of the pump cavity corresponding to the second water outlet B 1712 is tangent to the tangent line, which is the setting direction of the second water outlet B, and at this time the second water outlet B is parallel to the second water outlet A. When the impeller 3 rotates in the direction of W2, the water flows out from the second water outlet A 1711 and the second water outlet B 1712, and since the first water outlet 161 and the third water outlet 181 are opposite the tangent direction of rotation at this time, the water basically does not flow out from the first water outlet 161 and the third water outlet 181. When the impeller 3 rotates in the direction of W1, the water flows out from the first water outlet 161, the second water outlet A 1711, and the third water outlet 181, and since the second water outlet B 1712 is opposite the tangent direction of rotation at this time, the water basically does not flow out from the second water outlet B 1712.

[0101] (2) As shown in Fig. 14b, the second water outlet channel includes a second water outlet B 1712 and a second water outlet C 1713. The opening of the second water outlet B 1712 is directed towards a tangent direction parallel to the outer edge of the corresponding pump cavity, and the direction of the second water outlet B is along the water flow direction when the impeller rotates in the second direction. The opening of the second water outlet C is directed towards a tangent direction parallel to the outer edge of the corresponding pump cavity, and the direction of the second water outlet C is along the water flow direction when the impeller rotates in the first direction. When the impeller 3 rotates in the W2 direction, water flows out from the second water outlet B 1712, and since the first water outlet 161, the second water outlet C, and the third water outlet 181 are all directed against the tangent direction of rotation at this time, water basically does not flow out from the first water outlet 161, the second water outlet C, and the third water outlet 181. When the impeller 3 rotates in the W1 direction, water flows out from the first water outlet 161, the second water outlet C 1713, and the third water outlet 181, and since the second water outlet B 1712 is directed against the tangent direction of rotation at this time, water basically does not flow out from the second water outlet B 1712.

[0102] (3) As shown in Fig. 14c, the second water outlet channel includes a second water outlet B 1712 and a second water outlet D 1714. The opening of the second water outlet B 1712 is directed towards a tangent direction parallel to the outer edge P3 of the corresponding pump cavity (along W2), i.e. the direction of the second water outlet B 1712 is along the water flow direction when the impeller rotates in the second direction. The opening of the second water outlet D 1714 is directed towards a tangent direction of the outer edge P3 of the corresponding pump cavity (along W1) at an angle β5 = 48°. When the impeller 3 rotates in the W2 direction, water flows out from the second water outlet B 1712 and the second water outlet D, and since the first water outlet 161 and the third water outlet 181 are directed against the tangent direction of rotation at this time, water basically does not flow out from the first water outlet 161 and the third water outlet 181. When the impeller 3 rotates in the W1 direction, water flows out from the first water outlet 161, the second water outlet D 1714, and the third water outlet 181, and since the second water outlet B 1712 is directed against the tangent direction of rotation at this time, water basically does not flow out from the second water outlet B 1712.

[0103] As shown in Fig. 15, in this embodiment, the first water outlet channel 16 is provided with a first water outlet 161, the second water outlet channel 17 is provided with a second water outlet 171, and the third water outlet channel 18 is provided with a third water outlet 181. The first water outlet 161 corresponds to the point P5 on the outer edge of the pump cavity, and the tangent line along P5 (in the direction of W1) is the setting direction of the first water outlet 161. The opening direction of the second water outlet 171 is set at an angle β with the tangent direction of the corresponding pump cavity outer edge, and the angle β > 30°. In the figure, the point P6 on the outer edge of the pump cavity corresponding to the second water outlet 171 is P6, and a tangent line q2 is drawn along P6, and the opening direction of the second water outlet 171 is at an angle β2 = 60° with the tangent line q2. The third water outlet 181 corresponds to the point P7 on the outer edge of the pump cavity, and the tangent line along P7 (in the direction of W1) is the setting direction of the third water outlet 181. When the impeller 3 rotates in the direction of W1, the water flow mainly flows out from the first water outlet 161 and the third water outlet 181, and some flows out from the second water outlet 171. When the impeller 3 rotates in the direction of W2, the water flow flows out from the second water outlet 171, and since the first water outlet 161 and the third water outlet 181 are in the direction opposite to the tangent line at this time, the water flow basically does not flow out from the first water outlet 161 and the third water outlet 181.

[0104] By such a principle, when the impeller 3 rotates in the first direction, the water flow flows out from the first water outlet 161, the third water outlet 181, and at least one second water outlet 171 at the same time, and at this time, the water flow of the second water outlet channel > 5 L / min. When the impeller 3 rotates in the second direction, the water flow basically flows out from the second water outlet 171, and the water flow of the second water outlet channel > 8 L / min; does not flow out from the first water outlet 161 and the third water outlet 181, or only a small amount of water flows out from the first water outlet 161 and the third water outlet 181. Through such a structure, the water pump of the present application is suitable for two application scenarios of the toilet: when it is necessary to enter the drainage mode, the water flow needs to flow out from the first water outlet channel, the second water outlet channel, and the third water outlet channel at the same time; and when it is necessary to enter the washing, water replenishing, and wall moistening mode, the water flow only flows out from the second water outlet channel alone, so as to save water consumption.

[0105] With the above principle, combined with Figs. 12, 13, and specific to the embodiments of the present application, the second water outlet channel 17 is provided as a cylindrical pipe body, the cylindrical pipe body is provided with a pump cavity connecting section 172 and a confluence section 173, the pump cavity connecting section 172 is provided with a through second water outlet A 1711 and a second water outlet B 1712. The confluence section 173 has a confluence outlet 1731, the confluence section 173 is integrally formed with the pump cavity connecting section 172, or the confluence section 173 is sealingly assembled to the pump cavity connecting section 172. The confluence outlet 1731 is in communication with the second water outlet A 1711 and the second water outlet B 1712. By providing the confluence section 173, in specific applications, only one pipe needs to be connected, improving the convenience of connection, and reducing the volume of the water pump. As shown in Fig. 12, when the impeller 3 rotates along the W1 direction, the water flows out from the first water outlet 161, the second water outlet A 1711 and the third water outlet 181 (the solid arrow direction in the figure is the water flow direction), since the second water outlet B 1712 is opposite to the tangent direction of rotation at this time, the water basically does not flow out from the second water outlet B 1712. As shown in Fig. 13, when the impeller 3 rotates along the W2 direction, the water flows out from the second water outlet A 1711 and the second water outlet B 1712 (the dotted arrow direction in the figure is the water flow direction), since the first water outlet 161 and the third water outlet 181 are opposite to the tangent direction of rotation at this time, the water basically does not flow out from the first water outlet 161 and the third water outlet 181.

[0106] In combination with Figs. 11 and 14a, in order to make the water flow as much as possible not to flow out from the first water outlet 161 and the third water outlet 181 when the impeller 3 rotates along the second direction (W2 direction), a wedge-shaped block 19 is further provided on the inner wall surface of the pump cavity 14. The wedge-shaped block 19 is provided at the end of the first water outlet 161 or the third water outlet 181, or two wedge-shaped blocks 19 are provided at the same time, the wedge-shaped block 19 is inclinedly provided along the inner wall of the pump cavity 14, the front end surface of the wedge-shaped block 19 protrudes from the first water outlet 161 or the third water outlet 181, and the rear end surface is smoothly connected with the inner wall of the pump cavity 14. Through this setting, when rotating along the second direction, the water flow is blocked by the wedge-shaped block 19, which can further avoid flowing out from the first water outlet 161 or / and the third water outlet 181, but flow along the wedge-shaped block to pass the first water outlet 161 or / and the third water outlet 181.

[0107] Embodiment four

[0108] The application discloses a flushing control method of a smart closestool. As shown in Fig. 16, the smart closestool is provided with a water pump, a drainage mechanism and a drainage base. The water pump is provided with a plurality of water outlets. The smart closestool is provided with a washing pipeline 6 or an assisting flushing pipeline 94, or preferably provided with both the washing pipeline 6 and the assisting flushing pipeline 94. The water pump motor can rotate in a first direction or a second direction. The closestool body 8 has a sitting cavity 81 and a containing water cavity 82. The water pump, the drainage mechanism and the drainage base are arranged in the containing water cavity 82.

[0109] The three modes of the smart closestool are as follows:

[0110] 1. The drainage mode: the water pump drives the drainage mechanism to open the drainage base 93 to flush the bottom of the sitting cavity 81.

[0111] 2. The washing mode: the sitting cavity 81 is provided with a washing hole 811 connected with the washing pipeline 6. The water outlet of the washing pipeline 6 flushes the upper part of the sitting cavity 81 of the closestool body.

[0112] 3. The assisting flushing mode: the assisting flushing pipeline 94 is connected to flush the bottom of the sitting cavity 81 by the water outlet of the assisting flushing pipeline 94.

[0113] One embodiment is that the flushing modes of the smart closestool include the drainage mode and the washing mode. The main principle steps of the flushing control method are as follows: controlling the water pump motor to rotate in the second direction to make the smart closestool enter the washing mode; and controlling the water pump motor to rotate in the first direction to make the smart closestool enter the drainage mode.

[0114] Another embodiment is that the flushing modes of the smart closestool include the drainage mode, the assisting flushing mode and the washing mode. The main principle steps of the flushing control method are as follows: controlling the water pump motor to rotate in the second direction to make the smart closestool enter the washing mode; and controlling the water pump motor to rotate in the first direction to make the smart closestool enter the drainage mode and the assisting flushing mode. When the water pump motor rotates in the first direction to enter the drainage mode and the assisting flushing mode, the two modes can be performed simultaneously or sequentially.

[0115] When the first direction is the clockwise direction (the forward direction of the water pump motor), the second direction is the counterclockwise direction (the reverse direction of the water pump motor). When the first direction is the counterclockwise direction, the second direction is the clockwise direction.

[0116] The water outlet of the water pump comprises a drainage outlet and a washing outlet, or simultaneously comprises a drainage outlet, a washing outlet and a flushing outlet. When the water pump motor is controlled to rotate in the second direction, so that the intelligent toilet enters the washing mode, the water flow mainly flows out through the washing outlet, and the flow rate of the washing outlet is greater than 12 L / min, and the lift of the drainage outlet is less than 2 m. When the water pump motor is controlled to rotate in the first direction, so that the intelligent toilet enters the drainage mode, or enters the drainage mode and the flushing mode, the water flow mainly flows out through the drainage outlet or mainly flows out through the drainage outlet and the flushing outlet, and the lift of the drainage outlet is greater than 3 m, and the flow rate of the washing outlet is less than 4 L / min.

[0117] Embodiment five

[0118] As shown in FIGS. 18-19, the application discloses an integrated water device, comprising a shell 91, a drainage mechanism 92, a water pump 1 and a drainage base 93, the water pump 1 and the drainage mechanism 92 are installed in the inner cavity of the shell 91, and the drainage base 93 is installed below the shell 91.

[0119] As shown in FIG. 20, the shell comprises an upper shell 912 and a lower shell 913, the upper shell 912 and the lower shell 913 are detachably connected by screws or buckles, and the drainage mechanism 92 and the water pump 1 are installed in the upper shell 912 and the lower shell 913, so as to form an inner cavity for accommodating the drainage mechanism and the water pump, and the inner cavity can also store water, and a water inlet hole is arranged at the bottom of the lower shell 913 to ensure that the water pump will not be idling. The water inlet hole is provided with a filter cover 911 to filter impurities and prevent the integrated water device from being blocked.

[0120] As shown in FIG. 21, the upper end side wall of the drainage base 93 is provided with a plurality of drainage inlets 931, and the lower end is a drainage outlet 932.

[0121] As shown in FIGS. 22 and 23, the drainage mechanism 92 comprises a valve body 922, a reset spring 923, a piston 924 and a water sealing rubber 921, and the valve body 922 is detachably connected with the lower shell 913. The upper end of the piston 924 is slidably connected in the inner cavity of the valve body 922, and a drainage liquid cavity 925 is formed between the piston 924 and the valve body 922. Two sealing rings are arranged in the inner cavity of the valve body 922, and the sealing rings are adapted to the outer wall of the piston 924, and the two sealing rings, the inner wall of the valve body 922 and the outer wall of the piston 924 constitute the drainage liquid cavity 925, and water can be injected into the drainage liquid cavity 925 to lift the piston 924. In addition, an air vent hole 926 is arranged on the valve body 922 and / or the piston 924 to communicate with the drainage liquid cavity 924, so as to avoid air resistance and also to drain water from the drainage liquid cavity 925. As long as the water flow rate of the air vent hole 926 is lower than the water flow rate of the drainage liquid cavity 925, the piston 924 can be lifted.

[0122] The lower end of the piston 924 extends outside the valve body 922, and the lower end of the piston 924 can extend outside the lower housing 913. The water sealing rubber 921 is connected to the lower end of the piston 924, and the water sealing rubber 921 is sealingly fitted to the water outlet 932 of the water drainage base 93. That is, when the piston 924 moves downward, the water sealing rubber 921 can sealingly close the water outlet 932 of the water drainage base 93, and when the piston 924 moves upward, the water sealing rubber 921 can open the water outlet 932 of the water drainage base 93.

[0123] The reset spring 923 is arranged in the inner cavity of the valve body 922, and the reset spring 923 is arranged above the piston 924. The upper end of the reset spring 923 abuts against the valve body 922, and the lower end of the reset spring 923 abuts against the piston 924. When the water pump pumps water into the water drainage cavity 925, the water pressure in the water drainage cavity 925 increases, the piston 924 moves upward against the elastic force of the reset spring 923, and the water sealing rubber 921 moves away from the water outlet 932 of the water drainage base 93, so that the water drainage base 93 can be opened to drain water. After the water pump stops pumping water into the water drainage cavity 925, the water in the water drainage cavity 925 can flow out from the air hole 926 and the water pump under the rebounding force of the reset spring 923. The piston 924 moves downward and blocks the water outlet 932 of the water drainage base 93.

[0124] In order to prevent the water pump from failing or being unable to work due to power failure, the water drainage mechanism can still be controlled. The water drainage mechanism is also provided with a rope control device 927 and a wire control pull rope 928. The rope control device 927 is arranged outside the valve body 922, one end of the wire control pull rope 928 is connected to the rope control device 927, and the other end of the wire control pull rope 928 passes through the valve body 922 and is connected to the piston 924. The rope control device 927 is a prior art and will not be described in detail. After the above arrangement, the water drainage mechanism has a double control mode. One is to mechanically control the water drainage action of the water drainage mechanism by the rope control device, and the other is to control the operation of the water pump by the electric control mode, so as to control the action of the water drainage mechanism.

[0125] As shown in FIGS. 24-26, the water pump 1 comprises a pump body 10, a motor 2 and an impeller 3. The pump body 10 comprises a pump shell 12 and a water outlet cover 11 which are detachably connected, and a pump cavity 14 is formed in the pump shell 12 and the water outlet cover 11. At least one water inlet 15 and at least two groups of water outlets are arranged on the water outlet cover 11, and the water inlet and the water outlets are communicated with the pump cavity. A connecting frame 111 is arranged in the water inlet 15 of the water outlet cover 11, and the connecting frame 111 is provided with an assembly hole 112 at the end. The motor 2 is fixedly connected with the impeller 3, and the motor shaft 22 is connected with the assembly hole 112 of the connecting frame 111.

[0126] The two groups of water outlets are respectively a first water outlet 161 and a second water outlet 171, and the number of the first water outlet 161 and the second water outlet 171 is one or more. A reference tangent line Q is drawn along the edge of the cross section of the pump cavity (the cross section is circular), and the direction of the reference tangent line Q is the tangent direction. The opening direction C of the first water outlet 161 and the second water outlet 171 is parallel to the tangent direction Q of the outer edge of the corresponding pump cavity, that is, C is parallel to Q. Or the opening direction C of the first water outlet 161 and the second water outlet 171 is set at an inclination angle a with the corresponding tangent direction Q, and the inclination angle a is ≤30°. The opening direction of the first water outlet 161 is the water flow direction when the motor 2 rotates in the first direction, and the opening direction of the second water outlet 171 is the water flow direction when the motor 2 rotates in the second direction. After such setting, when rotating in the first direction, water is mainly discharged through the first water outlet, that is, the flow of the first water outlet is increased; and when rotating in the second direction, water is mainly discharged through the second water outlet, that is, the flow of the second water outlet is increased. Through further setting of the two water outlets, the purposes of motor forward rotation and reverse rotation and control of time-sharing water discharge of the two water outlets can be achieved.

[0127] The first direction is the clockwise direction, and the second direction is the counterclockwise direction, or the first direction is the counterclockwise direction, and the second direction is the clockwise direction.

[0128] In the embodiment, one first water outlet is provided, which is a drainage port 161a, and one second water outlet is provided, which is a washing port 171a. When assembled, the drainage port 161a of the water pump is inserted and matched with the valve body 922 of the drainage mechanism, and a socket 922a can be arranged on the valve body 922 to be inserted and matched with the drainage port 161a, and the socket 922a is communicated with the drainage liquid cavity 925. Meanwhile, the valve body 922 of the drainage mechanism is also provided with a first positioning stop member 922b (such as a slot), and the outside of the pump body is provided with a second positioning stop member 10a (such as a plug) which is inserted and matched or clamped and matched with the first positioning stop member 922b. After such setting, the assembly of the drainage mechanism and the water pump can be facilitated. The washing port 171a is connected to the washing pipeline 6 outside the shell.

[0129] As shown in FIG. 26, in a specific application, the control motor 2 is first rotated in the second direction (the direction of the dashed arrow in the figure) and then rotated in the first direction (the direction of the solid arrow in the figure). When the motor is rotated in the second direction, the flow rate of the flushing opening is greater than 12 L / min, and the head of the drain opening is less than 2 m. When the motor is rotated in the first direction, the head of the drain opening is greater than 3 m, and the flow rate of the flushing opening is less than 4 L / min. Thus, the water flow is first mainly discharged from the flushing opening 171a, and the water flow is delivered to the above of the toilet bowl cavity through the flushing pipeline 6 for flushing; then, the rotation direction is switched to the reverse direction, and the water flow is mainly discharged from the drain opening 161a, thereby lifting the drain mechanism, so that the liquid in the water cavity is discharged through the drain outlet of the drain base, and the bottom of the toilet bowl cavity is flushed. In this way, the water is discharged through different outlets when the motor is rotated in different directions, and the effect of time-sharing water discharge (peak-shaving water discharge) of the drain and flushing is achieved.

[0131] As shown in FIGS. 27 and 28, the difference between the present embodiment and embodiment five is that the present embodiment further includes an auxiliary flushing pipeline 94. As shown in FIGS. 29 and 30, the first water outlet of the water pump is provided with two, which are the drain opening 161a and the auxiliary flushing opening 161b, and the second water outlet is provided with one, which is the flushing opening 171a. The drain opening 161a is in communication with the drain mechanism 92, and the auxiliary flushing opening 161b is connected to the auxiliary flushing pipeline 94. The flushing opening 171a is connected to the flushing pipeline 6 outside the shell.

[0132] As shown in FIG. 27, the auxiliary flushing pipeline 94 includes a reverse U-shaped pipe 942 and an auxiliary flushing pipe 943 connected in sequence. One end of the reverse U-shaped pipe 942 is in communication with the auxiliary flushing opening 161b, and the other end is in communication with the auxiliary flushing pipe 943. The top of the reverse U-shaped pipe 942 is provided with an anti-siphon hole 944. The anti-siphon hole 944 is higher than the working water level height set in the accommodation water cavity, so as to prevent siphon.

[0133] The auxiliary flushing pipe 943 is connected with the drain base 93, or the auxiliary flushing pipe 943 is integrally formed with the drain base 93. The end of the auxiliary flushing pipe 943 is bent out of the drain outlet of the drain base 93, so as to be consistent with the direction of the drain passage of the intelligent toilet. The auxiliary flushing pipe 943 is a Venturi pipe, and the diameter of the Venturi pipe gradually decreases, so as to achieve a better auxiliary flushing effect of the water flow.

[0134] As shown in FIG. 30, in use, the motor 2 rotates in the second direction (the dashed arrow direction in the figure) to enter the washing mode, i.e., water is mainly discharged from the washing port 171a, and the motor 2 rotates in the first direction (the solid arrow direction in the figure) to enter the simultaneous drainage and flushing mode, i.e., water is mainly discharged from the drainage port 161a and the flushing port 161b. In a specific application, when the motor rotates in the second direction, the flow rate of the washing port is greater than 12 L / min, and the head of the drainage port is less than 2 m; when the motor rotates in the first direction, the head of the drainage port is greater than 3 m, and the flow rate of the washing port is less than 4 L / min. Thus, water is mainly discharged from the washing port 171a, and the water flow is delivered to the upper part of the toilet bowl cavity through the washing pipeline 6 to perform washing; then, the rotation direction is switched, and water is mainly discharged from the drainage port 161a and the flushing port 161b: the water flow of the drainage port 161a lifts the drainage mechanism, so that the liquid in the water cavity is discharged from the drainage outlet 932 of the drainage base to realize flushing of the sewage outlet at the bottom of the toilet bowl cavity. The water from the flushing port 161b is discharged from the flushing pipeline 943 through the drainage outlet 932 of the drainage base to realize assisted flushing of the sewage outlet at the bottom of the toilet bowl cavity.

In order to ensure the water pressure or flow rate of the water discharged from the main port, it is required that the cross-sectional area of the main port is larger than that of the secondary port, and the depth H of the pump cavity 14 is not less than the diameter of the main port. After such arrangement, the water pressure or flow rate of the water discharged from the main port can be ensured.

[0141] As shown in Fig. 38, two water outlets are provided, one first water outlet 161 and one second water outlet 171. The main port 161z of the first water outlet is oriented in the direction of water flow when the impeller rotates in the first direction, and the main port 171z of the second water outlet is oriented in the direction of water flow when the impeller rotates in the second direction, the first direction being opposite to the second direction. The first direction can be the clockwise direction (motor forward), and the second direction can be the counterclockwise direction (motor reverse), or the first direction can be the counterclockwise direction, and the second direction can be the clockwise direction. When the motor 2 rotates in the clockwise direction, the main port 161z of the first water outlet is mainly used for water outlet (large flow rate), and the main port 171z of the second water outlet is not used for water outlet (or small flow rate). The auxiliary port 161f of the first water outlet is not used for water outlet or is used for small flow rate, and the auxiliary port 171f of the second water outlet is used for small flow rate.

[0142] As shown in Fig. 39, when the motor 2 rotates in the counterclockwise direction, the main port 171z of the second water outlet is mainly used for water outlet (large flow rate), and the main port 161z of the first water outlet is not used for water outlet (or small flow rate). The auxiliary port 161f of the first water outlet is used for small flow rate, and the auxiliary port 171f of the second water outlet is not used for water outlet or is used for small flow rate. In this way, by controlling the forward and reverse rotation of the motor 2, the main port 161z of the first water outlet and the main port 171z of the second water outlet can be used for water outlet at different times (peak-shaving water outlet). When the water pump is placed in the pool, all auxiliary ports can be connected to the pool, so that the water volume in the pool is not lost, and the influence on the water outlet volume of the main port is small. Of course, the auxiliary ports can also be connected to other places by pipes for continuous small flow rate water supply.

[0143] As shown in Figs. 40-42, in another embodiment, three water outlets are provided, including two first water outlets 161 and one second water outlet 171. The main ports 161z of the two first water outlets are respectively a drain port 161a and a flushing port 161b, the drain port 161a is connected to the drain mechanism 92, and the flushing port 161b is connected to the flushing pipe 94, the other end of the flushing pipe 94 is connected to the drain outlet 932 of the drain base 93. The main port 171z of the second water outlet is a washing port 171a, which is connected to the washing pipe 6 outside the shell 91.

[0144] The main port 161z of the first water outlet is oriented in the direction of water flow when the motor 2 rotates in the first direction (clockwise direction in the figure), and the main port 171z of the second water outlet is oriented in the direction of water flow when the motor 2 rotates in the second direction (counterclockwise direction in the figure).

[0145] Due to the two first water outlets 161, when the impeller rotates in the first direction, the main outlets 161z of the two first water outlets can simultaneously discharge water, and when the impeller 3 rotates in the second direction, the main outlets 161z of the two first water outlets can simultaneously stop discharging water. As other extensions, more first water outlets 161 or more second water outlets 171 can also be provided to adapt to different water supply application scenarios, which will not be described again.

[0146] In the embodiment, the water flow mainly discharges from the drainage outlets 161a and the flushing outlets 161b when the motor rotates in the forward direction, that is, the drainage mechanism 92 controls the drainage base 93 to flush water, and the flushing pipeline 94 performs flushing, the lift of the drainage outlet is greater than 3 m, and the flow of the washing outlet is less than 4 L / min. When the motor rotates in the reverse direction, the water flow mainly discharges from the washing outlet 171a through the washing pipeline 6, the flow of the washing outlet is greater than 12 L / min, and the lift of the drainage outlet is less than 2 m. Of course, according to the structural design of different water pumps, other water discharge modes can also be realized.

[0147] The integrated water piece in the embodiment is used in the intelligent toilet, can realize different mode time-sharing water discharge, has simple structure, and is convenient to control.

[0148] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
