Sewage discharge device of variable water-saving toilet

Abstract

The present invention relates to a sewage discharge device of a variable water-saving toilet, the device discharging sewage in a bowl to the outside by the load of an auxiliary tank, when a part of tap water branches off from a tap water inflow path such that the tap water stored in the auxiliary tank provided around the outer periphery of a sewage discharge pipe of the toilet reaches a predetermined amount or more.

Description

technical field [0001] The present invention relates to a sewage discharge device for a variable water-saving toilet, and relates to a sewage discharge device for a variable water-saving toilet in which a part of the direct supply water is diverted from the direct supply water flow path, if it is formed in the toilet When the direct-supply water stored in the auxiliary tank on the outer periphery of the sewage discharge pipe exceeds a predetermined amount, the sewage in the barrel is discharged to the outside by the load of the auxiliary tank. Background technique [0002] In general, the toilet seat utilizes the principle of a siphon that stores a predetermined amount of water in the toilet seat for smooth cleaning of foul smell and excrement discharged from the excrement outlet. [0003] The principle of this siphon is as follows. When the water level in the reverse U-shaped pipe and the water level in the toilet are balanced, the water is in a stopped state. The pressure...

Problems solved by technology

[0007] Therefore, in the past toilet, even if the water is supplied to the inside of the barrel through the direct water supply channel of the water pipe with a caliber of about 15mm, since the diameter of the barrel discharge pipe is usually about 45-55mm, the siphon phenomenon cannot occur, but directly through The barrel discharge pipe is discharged, so that the dirt inside the barrel cannot be cleaned

[0008] Therefore, in the past, in the case of male urinals, direct connection of water pipes was generally used, and automatic cleaning was carried out by detectors, etc., but in the case of toilets, for the above reasons, it was impossible to directly connect water pipes to clean the sewage. cleaning, so that automatic toilets cannot be popularized

[0009] At the same time, the previous toilets (except for some toilets with a water supply diameter of 1 inch) must have the function of a sink before they can be cleaned. Therefore, due to design restrictions and sinks, the size of the toilet cannot be reduced, which is restricted by space.

In addition, when the toilet (also known as one-piece toilet) is manufactured by integrating the sink and the base, the production yield will decrease due to the increase in the defective rate, resulting in an increase in cost

[0010] At the same time, it is difficult for users to easily detect water leakage due to defects in the water supply pipe installed inside the tank, and users may not be aware of it until they check the water and sewage charges.

In addition, in the case of toilets used in public places such as public toilets or office buildings, since there is no sink, in order to use it through direct water supply, a pipe with a diameter of 25mm (1 inch) is installed separately from the general 15mm water pipe to be able to use it in a short time. A large amount of water is supplied inside, which requires a huge equipment cost. When the lever is working, it will be accompanied by serious noise due to the phenomenon of water hammer, so it cannot be used for general residential use.

[0011] At the same time, the variable double straight pipe of Korean Patent No. 10-1131810 variable double straight pipe water-saving toilet can move through the previous water supply flow path and the edge of the bucket body. When the water pipe supplies direct water, if the bucket When the water level inside the bucket rises, the variable straight pipe goes down, so that the dirt can be discharged, and the pressure of the water pipe drops sharply in the water path leading to the water tank and the inside of the bucket body and the water path inside the edge of the bucket body. As a result, the water pipe pressure cannot be used. , so that the cleaning of the dirt inside the barrel is facing a problem. When the dirt is discharged, it is difficult to adjust the downward extension time of the variable linear pipe, so sometimes a part of the dirt backflow occurs.

[0012] At the same time, the variable double straight pipe of Korean Patent No. 10-1131810 variable double straight pipe water-saving toilet needs to supply straight water to the barrel until the variable double straight pipe for discharging sewage descends, and the straight water supplied The supplied water is directly mixed with the sewage stored in the barrel so that the supplied direct supply water also becomes sewage, and as a result, washing water will be wasted and the water saving effect will be halved

[0013] At the same time, the variable double straight pipe of the variable double straight pipe water-saving toilet of Korean Patent No. 10-1131810 uses part of the water in the auxiliary tank on the outer periphery of the sewage discharge pipe, so that after a predetermined period of time, , due to the clogging phenomenon caused by the sewage flowing into the auxiliary tank, and the durability problem that the discharge unit malfunctions due to the malfunction of the sewage discharge pipe
