The present application proposes a toilet 1 comprising a tank 20, a bowl 100, a water pump 30 and a flush line 40. Referring to fig. 1, as an embodiment, a toilet 1 includes a ceramic body 10, and a bowl 100 is formed on the ceramic body 10. A receiving chamber 200 may be provided at one side of the urinal 100, and the receiving chamber 200 has a mounting port 210. The toilet may further include a mounting plate (not shown) which may be fitted to the mounting hole 210 and selectively close or open the receiving chamber 200. The receiving chamber 200 is used to set the water tank 20, the water pump 30, and other accessories of the toilet 1. The tank 20 is in communication with the bowl 100 via a flush line 40, and the toilet 1 may pump water from the tank 20 via the pump 30 into the bowl 100 via the flush line 40. The bottom of the urinal 100 is communicated with a sewage outlet 130, and the urinal 100 is communicated with a sewage pipeline through the sewage outlet 130. In some embodiments, the toilet 1 may further include a cover (not shown) that is hinged to the toilet 1 by a hinge mechanism and selectively opens or closes the opening 101 at the top of the bowl 100. In some embodiments, the toilet 1 further comprises a control device, which may be in communicative connection with the water pump 30. The water pump 30 may start or stop pumping water into the bowl 100 in response to a signal from the control device. As an embodiment, the toilet 1 may further include a flush button, the flush button is in communication with the control device, and the control device may respond to the flush button and send a signal to the water pump 30 to control the water pump 30 to flush water. When needing to wash by water, the user only need press the button alright realize washing by water, and the operation is comparatively simple. In other embodiments, the toilet 1 may further include a sensor, the sensor may be in communication with the control device, the sensor is used for identifying whether the user leaves the toilet 1, and the control device may obtain a signal from the sensor and send a signal to the water pump 30 to control the water pump 30 to flush water.

Urinal 100 is used to collect waste such as feces. Referring to fig. 2, the bowl 100 may be formed on the ceramic body 10 and provided with a washer hole 110 and a main punch hole 120, and the washer hole 110 and the main punch hole 120 communicate with the bowl 100. The washer hole 110 may be located above the main punch hole 120 for spraying water and cleaning the sidewall 102 of the urinal 100. The bowl 100 is generally funnel shaped so that dirt can slide down the side wall 102. The top of the bowl 100 is provided with an opening 101, and a seat (not shown) may be provided on the opening 101 for supporting a user. The washer aperture 110 may be disposed below the opening 101. As one embodiment, the washer aperture 110 may be disposed horizontally along the sidewall 102 of the urinal 100 such that water emitted from the washer aperture 110 is flushed in a single direction across the sidewall 102. In other embodiments, the urinal 100 may be further provided with a sub-channel (not shown) disposed below the opening 101 and communicating with the washer hole 110. The runners may be disposed around the opening 101. Flushing holes can be arranged on the branch channel at intervals. After the water flow enters the branch channel from the wash-ring hole 110, the water flow can uniformly flow out along the inner wall of the urinal 100 through each flushing hole, so that the inner wall of the urinal 100 can be cleaned.

Referring to fig. 2, when the water is stored in the urinal 100 and the stored water is discharged to the sewage pipe, the stored water can be discharged together with the filth in the urinal 100. The main punch hole 120 is disposed at one side of the soil discharge opening 130 and is used to flush water to the soil discharge opening 130. According to bernoulli's principle, when the main punch 120 flushes water into the sewage hole, because the water flow speed is fast, and simultaneously, under the action of gravity, the water flow flows downwards, negative pressure is formed in the pipeline, and the water stored in the urinal 100 and the sewage are sucked into the sewage outlet 130 together. In this embodiment, a communication portion 140 communicating with the main punch hole 120 may be further formed at the bottom of the urinal 100, and the urinal 100 may include an elbow 150, and the elbow 150 may be bent upward to connect the urinal 100 and the sewage pipe. The trap 150 may be partially raised above the bottom of the bowl 100 so that the water stored in the bowl 100 is not drained directly from the waste outlet 130 by gravity. The aperture of the communicating portion 140 is larger than the pipe diameter of the bent pipe 150, so that the dirt can smoothly enter the bent pipe 150, and is prevented from being stuck at the inlet of the bent pipe 150.

The water tank 20 is used to supply water for flushing to the main punch hole 120 and the washer hole. When the tap water pipe is directly communicated with the flushing pipeline 40, the flushing effect of the flushing pipeline 40 is influenced by the water pressure in the tap water pipe, and under the condition of a certain pipe diameter, the flushing quantity changes along with the change of the water pressure, so that the water tank 20 can be arranged on the closestool 1. Referring to fig. 3, in the present embodiment, the water tank 20 may be disposed at one side of the bowl 100 of the toilet 1 and is communicated with the seat hole 110 and the main punching hole 120 through the flushing pipe 40. As an embodiment, the water tank 20 may be selectively connected to or disconnected from the tap water pipe by a ball cock (not shown) so that the water in the water tank 20 is always maintained at a certain level. The ball float is always positioned on the water surface in the water tank 20 due to the buoyancy. When the water level in the water tank 20 is lower than the preset water level, the ball float valve is lowered, so that the water tank 20 is communicated with the tap water pipe, and the tap water enters the water tank 20 under the pressure of the pipe. When the water level in the water tank 20 is kept level with the preset water level, the ball float valve rises under the action of buoyancy, so that the water tank 20 is disconnected from the tap water pipe, and the water level in the water tank 20 does not rise any more.

When the water in the water tank 20 is used for flushing, because the volume of the water tank 20 is limited to a certain extent, the water pressure in the water tank 20 cannot meet the design requirement of flushing, so that the water pump 30 can be additionally arranged between the water tank 20 and the flushing pipeline 40, the water pump 30 in the water tank 20 is discharged by the water pump 30, and the water is pumped into the flushing pipeline 40 at a constant flow rate, so as to realize a stable flushing effect. Referring to fig. 3, in the present embodiment, the water pump 30 includes a water inlet end 31 and a water outlet end 32. The water pump 30 can drive water flow in from the water inlet end 31 and out from the water outlet end 32. The water inlet end 31 is disposed at one side of the water tank 20 and is communicated with the water tank 20, and the water outlet end 32 is communicated with the flushing pipe. In order to enable the water pump 30 to enable water flow to enter the water inlet end 31 when the water level is low, the water inlet end 31 can be communicated with the position close to the bottom of the water tank 20. In other embodiments, the water pump 30 may be a submersible pump, and the water pump 30 may be disposed within the tank 20 along with the inlet end 31 and the outlet end 32 in communication with the flush line 40. In some embodiments, the water pump 30 may be a pressure pump, the water inlet end 31 of the water pump 30 may be connected to a tap water pipe, and the water outlet end 32 of the water pump 30 is connected to the flushing pipe 40, so as to achieve a stable flushing effect.

The flush line 40 is used to communicate the tank 20 with the bowl 100. In the present embodiment, referring to fig. 4, the flushing pipeline 40 includes a connecting pipe 41, a tee joint 42, a first water channel 43 and a second water channel 44. One end of the connecting pipe 41 is communicated with the water outlet end 32 of the water pump 30, and the other end is communicated with the tee joint 42. The two ends of the tee joint 42, which are not communicated with the connecting pipe 41, are respectively communicated with the first water channel 43 and the second water channel 44. The first water channel 43 is communicated with the tee joint 42 and the washer hole 110, and the second water channel 44 is communicated with the tee joint 42 and the main punching hole 120. The length of the first water passage 43 is smaller than that of the second water passage 44, so that the water pumped into the connecting pipe 41 by the water pump 30 is firstly flushed out of the washer hole 110 and then flushed out of the main punching hole 120.

As an embodiment, the connection pipe 41 may be vertically connected to the water outlet end 32 of the water pump 30 to prevent water from flowing out of the main punching hole 120 due to gravity from the water tank 20 when the water pump 30 is not operated. The connecting pipe 41 includes a vertical section, a horizontal section and an elbow. The water outlet end 32 of the pump 30 may be disposed generally vertically upward and in communication with one end of the vertical section. The other end of the vertical section communicates with one end of an elbow, which may be a substantially right angle elbow, the other end of which communicates with a tee 42 via the horizontal section. In the case where the water pump 30 communicates the tank 20 with the connection pipe 41, the water level in the tank 20 and the water level in the connection pipe 41 are substantially the same in principle due to the communicating vessels. The height of the vertical section may be slightly lower than the top of the tank 20, and when the ball float in the tank 20 fails, the water in the tank 20 enters due to the running water, and after the horizontal level is higher than the height of the vertical section, the excess water can also flow into the horizontal section and flow out of the three-way pipe 42 into the urinal 100.

The tee joint 42 is used for communicating the horizontal section of the connecting pipe 41 with the first waterway 43 and the second waterway 44. Since the first water passage 43 and the second water passage 44 are simultaneously communicated with the tee joint 42, the water pressure in the first water passage 43 is substantially the same as the water pressure in the second water passage 44. In one embodiment, the tee 42 includes a first opening, a second opening and a third opening, and the tee 42 is respectively communicated with the first waterway 43 and the second waterway 44 through the first opening and the second opening and is communicated with the connecting pipe 41 through the third opening. The first opening and the third opening may be disposed opposite to each other, and the second opening may be disposed between the first opening and the third opening. When the water in the tank 20 is full and overflows from the connection pipe 41, the water flows into the tee joint 42 through the third opening, and flows into the second waterway 44 through the second opening under the action of gravity, and flows into the toilet bowl 100 through the main punching hole 120.

The first channel 43 and the second channel 44 may be partially formed as pipes or partially formed with the ceramic body 10, and are not limited thereto. The first and

second flumes

43, 44 may have different lengths to allow different times for water flow through the first and

second flumes

43, 44, respectively. In the present embodiment, the length of the first water passage 43 is set to L₁The second flume 44 has a length L₂. Therefore, according to the fluid characteristics, since the water pressure of the water flow flowing into the first waterway 43 is the same as the water pressure of the water flow flowing into the second waterway 44, the initial flow rates of the water flows flowing into the first waterway 43 and the second waterway 44 are also the same, and are denoted by v. The time required for the water to flow through the first water passage 43 is set to t₁The time required for the water flow to flow through the second water passage 44 is set to t₂Therefore vt₁＝L₁,vt₂＝L₂. In one embodiment, the length of the second flume 44 is greater than the length of the first flume 43, such that L₁＜L₂T since the initial flow velocity v of the water flow in the first channel 43 and the second channel 44 is the same₁＜t₂The water in the first water passage 43 will flow into the urinal 100 before the water in the second water passage 44, i.e., the water ejected from the rim hole 110 will flow out before the water ejected from the main punching hole 120. In the process of cleaning the dirt in the urinal 100, the water flow ejected from the washer hole 110 may first clean the dirt on the inner wall of the urinal 100 and flush the dirt into the water stored in the urinal 100. After a predetermined time interval, the water flow is flushed from the main bore 120 and the waste together with the water is discharged via the elbow 150 to the sewer line.

When the ratio of the length of the first water channel 43 to the length of the second water channel 44 is less than 1:5, the water in the wash ring hole 110 flows out too early, which may cause the urinal 100 to be overfilled. When the ratio of the length of the first water passage 43 to the length of the second water passage 44 is greater than 1:3, the predetermined interval time is too short to achieve the desired effect of the flushing. In the present embodiment, the ratio of the length of the first water passage 43 to the length of the second water passage 44 is greater than or equal to 1:5 and less than or equal to 1:3, so that the preset time interval can be maintained between 0.5S and 1.5S, and at the same time, after the water pump 30 stops pumping water, the water stored in the first water passage 43 and the second water passage 44 can flow into the toilet 100 by gravity and form a water storage in the toilet 100 for the next flushing.

In one embodiment, the diameters of the washer hole 110 and the main punched hole 120 may be different, so that when the water pressure in the first water passage 43 and the second water passage 44 is equal, the flow rate of the water flowing out of the washer hole 110 and the flow rate of the water flowing out of the main punched hole 120 have a certain ratio. It should be noted that, before the water flows in the first water channel 43 and the second water channel 44 reach the washer hole 110 and the main punched hole 120 respectively, since there is no water stored in the first water channel 43 and the second water channel 44, it is known from the fluid mechanics law that there is no pressure in the water flow process, and the flow rate of the water flow is not affected by the sizes of the washer hole 110 and the main punched hole 120. When the ratio of the diameters of the washer hole 110 to the main punch hole 120 is less than 2:5, the water flowing out of the main punch hole 120 flows through a large amount, so that the water stored in the toilet 1 is sucked away before the washer hole 110 flushes the dirt on the inner wall of the toilet 100, and a part of the dirt is left in the toilet 100. When the ratio of the diameters of the washer hole 110 to the main punched hole 120 is less than 4:5, the water flowing out of the washer hole 110 flows through a large area, and the water stored in the urinal 100 is easily over-high and overflows. In the present embodiment, the ratio of the diameters of the washer hole 110 and the main punch hole 120 is greater than or equal to 2:5 and less than or equal to 4:5, which can save water and achieve a good flushing effect.

The principle of use of the toilet 1 proposed by the present application is as follows:

the toilet 1 proposed in the present application is constructed by storing tap water in a tank 20 on the toilet 1. When it is desired to flush the toilet 1, the pump 30 is responsive to the control means and draws water from the toilet 1 through the inlet end 31 which is in communication with the tank 20 and drives the water through the outlet end 32 into the flush line 40. The water flows into the first water passage 43 and the second water passage 44, respectively, under the driving of the water pump 30. Due to the different lengths of the first and

second water courses

43, 44, the water flows through the first and

second water courses

43, 44 may have different times. The first channel 43 is shorter than the second channel 44 so that the water in the first channel 43 flows out of the flush ring hole first and flushes the side wall 102 of the toilet 100 for cleaning and flushes the waste into the water stored in the toilet 100. After a predetermined time, the water in the second water channel 44 is flushed out of the main punch 120, and a negative pressure is formed in the channel, so that the stored water in the toilet 100 is sucked away together with the sewage, and flows into the sewage channel from the sewage outlet 130 along the bent pipe 150. The application provides a closestool 1, owing to be provided with water tank 20 and water pump 30, the bath effect can not receive the influence of running water hydraulic pressure, and washes by water with the main 120 intervals that punch a hole 110 of washer, has practiced thrift the water resource. Meanwhile, the flushing can be carried out only by controlling the water pump 30, and the control process is simple.

The above embodiments are only for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may be modified or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present application and are intended to be included within the scope of the present application.
