Abstract

The present invention relates to a toilet bowl with a changeable water seal, which comprises an upper region, a waste drain outlet of the upper region, a lower region and a waste drain outlet of the lower region. A deviated waste discharge passage is fixed on a supporting shaft or a supporting bore. A reposition apparatus is arranged for the reposition of the waste discharged passage, the lower end of which surrounds the waste drain outlet of the upper region, the higher end of which could be depressed and repositioned automatically and be lead to the waste drain outlet of the lower region. This invention could overcome these disadvantages that immobile waste discharge passage of the traditional toilet bowl between the waste drain outlet of the upper region and the waste drain outlet of the lower region has a higher water seal, a higher water resistance and higher water consume. The waste discharge passage of this invention is deviated automatically to form a lower water seal while flushing, and is repositioned automatically to form a higher water seal while non-flushing. It can not only seal the odour but also improve the flushing efficiency and save water. The structure of invention is simple and reliable and has lower cost.

Description

Instructions Variable watertight toilet

Technical field

The patent relates to a toilet, in particular to a variable water-sealed toilet. .

Background technique

The conventional water closet device for a toilet is a fixed curved drain channel with deep water retention, which includes an upper cavity, a lower cavity, an upper cavity drain, and a lower cavity drain. There is a water seal in the curve of the lower cavity. Odor, but at the same time, high water resistance is formed, which greatly reduces the flushing effect, resulting in serious waste of water; meanwhile, the curvature of the sewage channel is large, so the water resistance is increased, and it is easy to trap dirt, and even block the channel in severe cases To make the toilet fail.

Summary of the Invention

The purpose of this patent is to solve the shortcomings of the prior art, and provide a variable water-sealed flush toilet, which is provided with a deflectable sewage channel capable of changing the height of the water seal: the water seal is usually high and has an ideal plugging effect. When flushing, the height of the water seal can be lowered again to achieve the effect of reducing flushing resistance and reducing flushing water.

The purpose of this patent is achieved by the following solutions:

A variable water-sealed flush toilet includes an upper cavity, a lower cavity, an upper cavity sewage outlet, and a lower cavity sewage outlet. It is characterized in that a deflectable sewage channel is provided, and the deflectable sewage channel is installed on a support shaft or a support hole. On the upper side, the lower end surrounds the upper cavity drain, and the high end, which can be automatically lowered and automatically reset, is connected to the lower cavity drain, and is provided with a reset device capable of deflecting the drain channel.

The deflectable sewage channel described in the above scheme is rotatable about a support axis, and the upper limit of the rotational position is the high position of the deflectable sewage channel; the lower limit of the rotational position is the low position of the deflectable sewage channel. Normally, the deflectable sewage channel is kept high under the action of the reset device, so the water seal is high. When flushing, under the action of water current, the deflectable sewage channel overcomes the force of the reset device and rotates around the support shaft or support hole. Change to a low position to make the height of the water seal low, and achieve the effect of reducing flushing resistance and reducing flushing water. After flushing, under the action of the resetting device, the deflectable drainage channel is reset and continues to maintain a high water seal. The deflectable sewage channel may be a U¾ pipe sewage channel, a ~ 1-shaped pipe sewage channel, or another shape of a deflectable pipe sewage channel.

The resetting device may be selected with a repeating position device, a compression spring return device, a tension spring return device, a combination spring of a compression spring and a tension spring, or other devices capable of returning the deflectable drainage channel from a low position to a high position. .

The support shaft or the support hole of the deflectable sewage channel is installed outside the upper cavity sewage outlet or the lower cavity sewage outlet in the lower cavity.

More specifically, the purpose of this patent is further achieved by the following two technical measures:

a. The deflectable sewage channel is tubular, that is, the deflecting pipe sewage channel is structured as follows: a flexible pipe sewage channel is set on the outer groove of the elbow-shaped upper cavity sewage outlet, and then tightened with screws. In the support hole on the fixed clamp bracket, a deflection frame that can be deflected about an axis is supported. One side of the deflection frame is provided with a reset device, and the other side extends obliquely upward and extends in synchronization with the flexible pipe drainage channel or The pipe-shaped sewage channel connected with the flexible pipe sewage channel is connected to form a horizontal or vertical or inclined deflection sewage channel opening leading to the lower cavity sewage outlet, and is deflected and reset in synchronization with the deflection frame. There is a middle part of the mouth of one side of the deflection frame. The narrow plate is bent downward to form a convex block, and the narrow plate and the convex bent downward form a limit plate and a limit block that limit deflection and reset.

b. The deflectable sewage channel is groove-shaped, which can be changed into a water-sealed variable water seal. It includes a support hole on a hoop-type bracket fastened with screws on the outside of the upper cavity sewage outlet. Slotted sewage channel with shaft and deflection around the axis, the upper cavity sewage outlet extends into the lower end of the grooved sewage channel, the grooved sewage channel extends diagonally to the upper right to the horizontally deflected sewage outlet, and the left side of the grooved sewage channel has Reset the counterweight; the upper horizontal plate of the bracket is a limit plate, and the bending projection is a limit projection; the lower portion of the bracket is tightened with a screw.

The advantage of this patent is that it eliminates the disadvantages of the high-water seal, high water resistance, and therefore high water consumption of the fixed sewage channel between the upper cavity sewage outlet and the lower cavity sewage outlet of the conventional toilet. The sewage drainage channel is designed to automatically deflect when flushing. It is a low water seal, and a variable deflection sewage channel that automatically resets to a high water seal when it is not flushed, which not only seals off the odor, but also greatly improves the flushing effect, saves water, and has a simple and reliable structure. , High cost performance.
