Description

Technical FieldThe present invention relates to the field of sanitary technology, in particular a toilet.Prior ArtToilets, also called toilet bowls, are currently usually designed as deep-sinkers and siphon toilets. Its discharge channel has a first section for storing water (i.e. a siphon), a second section for connection to the waste water line and a curved third section which connects said first and said second section to one another. In a siphon toilet according to Fig. 4, the arrangement of its flushing water outlets is mainly such that a first flushing water outlet is arranged laterally on the inner wall of the toilet body so that the water flow along the inner wall forms a vortex to flush the inner wall and a second flushing water outlet is arranged in the first section (i.e. in the siphon) at the bottom of the toilet bowl. During use, a small amount of water is always stored in the first section, thereby forming an odor trap that prevents odors and noxious gases from flowing back out of the sewer.However, since the pipe of the third portion connecting the first and second portions is usually curved upward (i.e., the curved part is located upward), clogging may easily occur in the third portion. The arrangement of the existing two flushing water outlets flushing from inside the toilet body simultaneously flushes a large amount of contaminants from the first portion to the third portion and then discharges them, which easily leads to a blockage in the area of the third portion. Moreover, after occurrence of a blockage in the region of the third section, it is difficult to remove the latter.Summary of the Utility ModelOn the basis of this, the object of the present invention is to provide a toilet in order to solve the above-mentioned problems.In order to achieve the object, the present application provides a toilet comprising a toilet body, a drain passage connected to the bottom of the toilet body, a first flushing water pipe connected to a side surface of the inner wall of the toilet body, a second flushing water pipe connected to the first portion of the drain passage, and further a third flushing water pipe, the drain passage comprising a first portion connected to a chamber of the toilet body and serving for water storage, a second portion connected to a drain pipe, and a curved third portion serving to connect the first portion and the second portion, the third flushing water pipe being connected to the third portion.Furthermore, the outflow channel is a deep washer channel.Furthermore, the outflow channel is a siphon channel.Furthermore, the flushing water outlet of the third flushing water line is arranged directed downstream of the channel.Further, the first rinsing water line, the second rinsing water line, and the third rinsing water line are each connected to a water line system, and are each controlled independently or synchronously to open or close.Furthermore, the toilet comprises a water storage container and a pressure increasing device, wherein the water inlet of the water storage container is connected to the water line system and the water outlet is connected to the third flushing water line, wherein the pressure increasing device serves to pressurize the water in the water storage container so that it flows out of the third flushing water line in an accelerated manner.Further, the pressure increasing device is an air pump. The water storage tank includes a first water storage tank and a second water storage tank in communication with the first water storage tank. The water inlet is disposed on the first water storage tank, and the water outlet is disposed on the second water storage tank and provided with a first solenoid valve. At the connection point between the first and the second water storage container, a second solenoid valve is arranged. The air pump is in communication with an air inlet of the second water storage container.Furthermore, the air inlet is provided with a third solenoid valve.Furthermore, a liquid level sensor is arranged in the second water storage container. The water inlet is provided with a fourth solenoid valve electrically connected to the liquid level sensor.Furthermore, a check valve is also arranged on the third flushing water line.By the above-mentioned configurations, the present invention can achieve the following technical effects:The present utility model provides a toilet including a toilet body, a first flush water pipe connected to the side surface of the inner wall of the toilet body, a second flush water pipe connected to the first portion of the drain passage of the toilet body, and a third flush water pipe connected to the third portion of the drain passage. In a siphon toilet, if the drain channel is not clogged, the flushing through the third flushing water line allows a negative pressure to be rapidly generated in the drain channel. This enhances siphon action, thereby quickly draining contaminants and wastewater and reducing the occurrence of clogs. In contrast, in the case of a deep washer, the high-pressure flushing by the third flushing water line can quickly flush away the contaminants, which have been flushed into the third section by the first and second flushing water lines, from the third section, with the result that a blockage in the third section is avoided. When the third portion is clogged, the high-pressure water from the third flush water line can effectively flush the clog away regardless of whether it is a siphon toilet or a deep flush toilet, thus solving the clogging problem.DESCRIPTION OF THE FIGURESIn order to more clearly explain the configurations of the embodiments of the present invention, the drawings required for describing the embodiments will be briefly presented below.

Obviously, the described embodiments are only a part of the embodiments of the present invention and not all of the embodiments. Based on the embodiments in this utility model, all other embodiments that a person skilled in the art receives without inventive activity fall within the scope of this utility model. Therefore, the following detailed description of the embodiments of the present invention shown in the drawings is not intended to limit the scope of the claimed invention, but merely illustrates selected embodiments of the present invention. Based on the embodiments in this utility model, all other embodiments that a person skilled in the art receives without inventive activity fall within the scope of this utility model.Exemplary EmbodimentReferring to FIGS. 1 to 3, this embodiment provides a toilet including a toilet body 1, a drain passage connected to the bottom of the toilet body 1, a first flush water pipe 2 connected to a side surface of the inner wall of the toilet body 1, a second flush water pipe 3 connected to the first portion of the drain passage of the toilet body 1, and further including a third flush water pipe 4.The drain channel comprises a first portion 5 connected to a chamber of the toilet body 1, a second portion 6 connected to a sewer line and a third portion 7 serving to connect the first portion 5 and the second portion 6, the third sewer line 4 being connected to the third portion 7.In this exemplary embodiment, as shown in FIGS. 1 and 2, using the example of the siphon toilet and the deep-flushing toilet, the difference is that the siphon channel of the siphon toilet is overall S-shaped and can generate a siphon effect, while the deep-flushing channel of the deep-flushing toilet is relatively larger, does not generate a siphon effect and only relies on the water flow for the deep flushing. Specifically, the first rinsing water line 2, the second rinsing water line 3, and the third rinsing water line 4 are each connected to a water line system, and are each independently or synchronously controlled to be opened or closed. In the siphon toilet, the third flushing water pipe 4 is connected to the outer curved side of the third portion 7, and the flushing water outlet of the third flushing water pipe 4 is arranged facing downstream of the channel. In the siphon toilet, when the drain is not clogged, the flushing through the third flushing water pipe 4 enables a negative pressure to be rapidly generated, which enhances the siphon effect, so that contaminants and waste water are quickly discharged and clogs are reduced. In the deep washer toilet, the high-pressure flushing through the third flushing water line 4 can quickly flush away the contaminants flushed into the third section 7 through the first flushing water line 2 and the second flushing water line 3, so that blockage in the third section 7 is avoided. When the third portion 7 is clogged regardless of whether it is a siphon toilet or a deep washer toilet, the high-pressure water from the third flushing water pipe 4 can effectively flush the clog and solve the problem of the clog.In this case, the first flushing water line 2 and the second flushing water line 3 can also be controlled by a cisternless mechanical valve 12, as shown in FIGS. 4 and 5. Its specific structure is described in detail in Chinese Published Application No. 202111602783.7, entitled "A cisternless Mechanical Valve Scavenging System", and will not be explained here in detail. The third flush water line may be controlled by a separate control valve. The cisternless mechanical valve allows, by a retard adjustment of an activation chamber, a one time trip to control a master control piston to effect reciprocation. Meanwhile, the main control piston controls a flow path switching mechanism that switches the outlet line, thereby driving the water flow to complete the entire process of the edge purge, the jet purge, and the secondary edge purge for water storage. The entire process is completed by mechanical force without relying on the flow from the cistern.In another embodiment, as shown in FIG. 3, the toilet further comprises a water storage container and a pressure increasing device. The water inlet of the water storage tank communicates with the water piping system via a connection pipe 11, and the water outlet communicates with the third rinsing water piping 4. The pressure increasing device serves to pressurize the water in the water storage tank so as to flow out of the third flushing water pipe 4 in an accelerated manner.Specifically, the pressure increasing device is an air pump 10. The water inlet is disposed on the first water storage tank 8. The water outlet is arranged on the second water storage container 9 and is provided with a first solenoid valve. At the connection point between the first water storage container 8 and the second water storage container 9, a second solenoid valve is arranged. The air pump 10 is communicated with an air inlet of the second water storage container 9. The first solenoid valve and the second solenoid valve may cause the second water storage container 9 to form a sealed chamber when the air pump 10 pressurizes the second water storage container 9. At this time, when the second water storage container 9 is filled with a certain amount of water, the first solenoid valve and the second solenoid valve are closed, whereby the second water storage container 9 is in a closed state. Then, the air pump 10 pumps gas into the second water storage container 9 to pressurize the second water storage container 9. When the pressure reaches a certain value, the first solenoid valve opens. At this time, a high water pressure water flow is obtained which can considerably enhance the siphon action of the drain channel or can flush away the contaminants blocked in the third section 7 directly, thereby solving the blockage problem in the curvature region. It should be noted that the air inlet must be arranged at the top of the second water storage container 9 and be above the water level in order to avoid water backflow into the air pump 10.Preferably, a liquid level sensor is arranged in the second water storage container 9. The water inlet is provided with a fourth solenoid valve electrically connected to the liquid level sensor. When the liquid level sensor detects that there is insufficient water in the second water storage tank 9, the fourth solenoid valve opens the water inlet to perform the water storage for the second water storage tank 9. If the water pressure in the water piping system is insufficient, the water in this tank may serve as reserve water. When the liquid level sensor detects that the water is accumulated in the second water storage tank 9 to a certain level, the fourth solenoid valve closes the water inlet to prevent the liquid level from becoming too high, which could result in water backflow into the air pump 10.Furthermore, a third solenoid valve is arranged at the air inlet. During water filling of the second water storage tank 9, the third solenoid valve closes the air inlet, thereby avoiding overfilling of the second water storage tank 9 that could lead to water return to the air pump 10.Preferably, a non-return valve is also arranged on the third flushing water line 4 in order to prevent wastewater from flowing back from the outflow channel into the water storage container.Note that the above-described toilet may be a one-piece toilet, a multi-piece toilet, or a wall-hanging toilet, a floor-standing toilet, and a smart toilet, etc.; this is not specifically limited here.The above embodiments are only preferred embodiments of the present invention.
