Description

Technical Field

[0001] The present invention relates to the technical field of toilets, and particularly to a toilet overflow structure. Background Art

[0002] A water inlet switch is installed in the water tank of the toilet. After long-term use, the water inlet switch will inevitably have faults, generally manifested as delayed water shut-off or inability to completely shut off the water, resulting in a situation where the water level in the water tank is too high. For this reason, an overflow water structure is generally provided in the toilet water tank. Currently, for the overflow water structure of toilets on the market, most of them discharge the overflow water onto the toilet bowl surface. However, such a way of discharging the overflow water not only causes serious water marks on the toilet, but also requires the water tank to be made higher than the overflow port of the toilet bowl surface. This not only does not conform to the current trend of making the top surface of the water tank of intelligent toilets lower and flatter, but also makes it impossible to arrange the movement on the top of the water tank. Therefore, the present invention provides a new toilet overflow water structure to solve the above technical problems. Summary of the Invention

[0003] To solve the above technical problems, the present invention proposes a new type of toilet overflow structure, in which the overflow water does not need to pass through the toilet bowl surface, nor does it need to additionally install a drainage accessory communicating with the sewer.

[0004] A toilet overflow structure includes a toilet ceramic main body and a water tank.

[0005] The toilet ceramic main body is provided with a sewage pipe and a sewage branch. The water inlet end of the sewage pipe communicates with the toilet bowl surface, and the water outlet end forms a sewer docking port for discharging sewage and dirt in the toilet bowl surface, and also serves as the main flushing channel of the toilet. The sewage branch is arranged on the periphery of the sewage pipe, with one end communicating with the sewage pipe and the other end forming an upward sewage outlet.

[0006] The water tank is provided with a vertically arranged overflow channel. The top of the overflow channel is the water inlet, and the bottom is the water outlet. The water inlet is arranged in the water storage cavity for the excess water in the water storage tank to flow in, and the water outlet is arranged at the bottom of the water tank. The water tank is installed in the toilet ceramic main body, and the water outlet communicates with the sewage outlet, so that the overflow water in the water tank can be discharged into the sewage branch.

[0007] The toilet overflow structure provided by the present invention adds an additional sewage branch with a sewage outlet to the toilet ceramic main body and docks the water outlet of the water tank overflow channel, so that the overflow water does not need to pass through the toilet bowl surface, and no additional drainage accessories need to be installed during installation, providing a new way to discharge the overflow water of the toilet, with a simple structure and good discharge effect of the overflow water.

[0008] Preferably, to increase the function of the overflow structure, the toilet overflow structure further includes a vertically arranged deodorization channel. The top of the deodorization channel is an air inlet, which can be connected to the exhaust end of the suction pump of the toilet deodorization device. The bottom of the deodorization channel is an air outlet, and the air outlet is also communicated with the sewage outlet, so that the odor sucked by the toilet deodorization device can be directly discharged into the sewer, thus eliminating the need for odor purification treatment and simplifying the toilet deodorization mechanism.

[0009] Preferably, to improve the compactness of the overflow structure, the deodorization channel is arranged in the water storage cavity of the water tank. The air inlet extends to the top of the water tank, and the air outlet is communicated with the lower part of the overflow channel and is communicated with the sewage outlet through the drain outlet of the overflow channel, which can reduce the number of pipes directly connected to the sewage outlet and reduce the installation difficulty.

[0010] Preferably, to reduce the molding difficulty of the water tank, the overflow channel includes an overflow hole and an overflow pipe. The overflow hole is arranged at the bottom of the water storage tank. The top end has a docking head in the water storage cavity, and the bottom end extends downward at the bottom of the water tank and is provided with the drain outlet. The bottom end of the overflow pipe is installed at the docking head, and the top end forms the water inlet.

[0011] Preferably, to increase the function of the water tank, the water tank is also provided with a sewage channel. The sewage channel is a channel for exhausting or draining water, and a lateral socket is provided at the bottom end of the sewage channel. A lateral socket is provided around the docking head of the overflow hole. The bottom end of the sewage channel is inserted and communicated around the docking head of the overflow hole.

[0012] Preferably, in the water tank, a one-way valve is provided in the channel communicating with the sewage outlet, which can prevent the odor or sewage in the sewage outlet from flowing back and overflowing.

[0013] Preferably, an installation cavity is provided in the channel, and an installation bracket is provided in the installation cavity. The one-way valve includes a telescopic rod and a spring. The top end of the telescopic rod is provided with an overflow cover, and a sealing gasket is installed on the top of the overflow cover. The bottom end of the telescopic rod is telescopically installed on the installation bracket. The spring is sleeved outside the telescopic rod, with the top against the overflow cover and the bottom against the installation bracket. The spring provides the force for the overflow cover to seal the water inlet at the top of the installation cavity.

[0014] Preferably, to increase the function of the overflow structure, the water tank is provided with a tank cover. The tank cover is provided with a vertical overflow channel. The top of the overflow channel is communicated with the overflow hole arranged at the upper edge of the toilet bowl surface, and the bottom is a water outlet and is located directly above the drain outlet of the overflow channel. When the S-bend of the toilet is blocked, the water about to overflow in the toilet bowl can be discharged into the sewer through the overflow channel and the sewage branch, preventing the sewage from overflowing the toilet bowl surface.

[0015] Preferably, the bottom surface of the internal passage of the sewage branch is inclined, or the sewage branch is an inclined pipe with the end far from the sewage pipe being higher, which is conducive to the dirt in the sewage branch entering the sewage pipe and preventing the dirt from accumulating in the sewage branch.

[0016] Preferably, a connecting seat is provided at the bottom of the toilet ceramic body, and the drainage branch is arranged in the connecting seat. One side of the connecting seat is connected to the sewage pipe, and the other side is connected to the side wall of the toilet ceramic body, improving the integrity and strength of the internal structure of the toilet ceramic body. The top surface of the connecting seat is flat, and the sewage outlet is arranged on the top surface of the connecting seat. The space on the top surface of the connecting seat forms a water tank installation space, and the top surface of the connecting seat forms a water tank support surface, which can provide sufficient installation space and stable support for the water tank.

[0017] As can be seen from the above description of the present invention, the present invention has the following beneficial effects: The toilet overflow structure provided by the present invention adds an additional sewage branch with a sewage outlet to the toilet ceramic body and docks with the drainage outlet of the water tank overflow channel. Thus, the overflow water does not need to pass through the toilet bowl surface, and no additional drainage fittings need to be installed during installation, providing a new discharge method for the overflow water of the toilet. The structure is simple, and the discharge effect of the overflow water is good; The toilet overflow structure provided by the present invention allows the toilet water tank to be made lower than the toilet bowl surface. On the one hand, it conforms to the current trend of making the toilet water tank lower and flatter. On the other hand, it vacates the space at the top of the water tank, providing a more sufficient installation space for the intelligent toilet movement; The toilet overflow structure further includes a deodorization channel communicating with the sewage outlet, which can directly discharge the odor sucked by the toilet deodorization device into the sewer, thus eliminating the need for odor purification treatment, simplifying the toilet deodorization mechanism, and also increasing the functions of the overflow structure; The lid of the water tank is also provided with an overflow channel, which can discharge the water about to overflow in the toilet bowl into the sewer when the toilet S-bend is blocked, preventing the sewage from overflowing the toilet bowl and also increasing the functions of the overflow structure.
