Description

A toilet structure

technical field

The invention relates to a toilet structure, in particular to a pressure jet siphon type toilet structure.

Background technique

The pressure jet siphon toilet adds a jet sub-channel at the bottom of the toilet, aiming at the center of the sewage outlet. When flushing, part of the water flows out from the flushing edge of the toilet ring, and part of the water is ejected from the jet port. The large water flow produces a siphon to quickly wash away the dirt.

The traditional toilet structure is shown in Figure 7. In the traditional structure, the inventors have found the following problems through long-term thinking and a lot of practice: 1. When flushing, the lower spray flushing water flow flushed out by the lower nozzle easily collides with the ceramic surface, resulting in The flow resistance of the water flow increases, and the distance of the jet water flow is long, and the direction of the water flow does not correspond to the position of the siphon port, resulting in poor siphon effect and low utilization of the water flow.

2. Due to the narrow position of the dirt collection during flushing, the dirt is easily blocked when the downward jet is flushed out, and it is easy to splash and splash on the user's buttocks, which affects the customer's perception of the toilet.

3. The siphon can only be generated at a lower pressure, such as about 0.1MPa or more, and the siphon diameter is small, which is prone to blockage for household use, and the sewage discharge capacity is poor. The toilet needs to be cleaned frequently, which affects the use of consumers.

Another toilet structure, such as the Chinese invention patent application number: CN03822732.0, the dirt in the toilet will fall on the ceramic surface, which is easy to cause the phenomenon of hanging feces.
