Embodiment 1

[0044] Hereinafter, the sealing water replenishment method of the sealing water device for drainage according to Embodiment 1 of the present invention and the pipeline opening and closing device used in the method will be described with reference to FIGS. 1 to 3 . In this embodiment, a method of replenishing the sealing water of the sealing water device for drainage of each sanitary appliance in a multi-storey house such as an apartment building will be described. Here, FIG. 1(A) is an overall schematic view showing the sealing water replenishment method of the sealing water device for drainage according to this embodiment. FIG. 1(B) is an outline view of the pipeline switch device. 2 is a schematic side view of a kitchen sink, and FIG. 3 is a perspective view showing a method for replenishing sealed water with respect to a water sealing device for drainage of other sanitary appliances.

[0045] First, before explaining the sealing water replenishment method of the sealing wat...

Embodiment 2

[0066] Next, referring to Fig. 5 and Fig. 6, the sealing water replenishment method of the sealing water device for drainage according to the second embodiment of the present invention and the pipeline opening and closing device used in the method will be described. The pipeline switch device of the present embodiment is a CPU built-in pipeline switch device, which is a structure in which the 4m pipeline in charge can be automatically switched between the slightly open state and the fully open state when going out.

[0067] As shown in FIG. 5 , the pipeline switch device 40 of this embodiment is composed of a main solenoid valve 42 , a bypass solenoid valve 44 , a bypass throttle valve 45 and a control unit 48 . Here, the pipeline area of ​​the bypass throttle valve 45 is set to a value substantially equal to the pipeline area of ​​the valve main body 32 during the slight opening operation in the integrated pipeline switch device 30 . For this reason, when the main solenoid va...

Embodiment 3

[0083] Next, the sealing water replenishing device of the sealing water device for drainage according to the third embodiment of the present invention will be described with reference to FIGS. 7 to 12 . The sealing water replenishing device of the sealing water device for drainage in this embodiment is a device that can automatically supply sealing water to the sealing water device for drainage under predetermined conditions even when the faucets of the water pipes of each sanitary appliance are closed. . Here, FIG. 7 is an overall piping system diagram of the sealing water replenishment device of the drainage sealing water device of this embodiment, FIG. 8 is a schematic diagram showing the control structure of the sealing water replenishing device of the drainage sealing water device, and FIG. Schematic diagram of a water level sensor. Fig. 10 is a flow chart showing the control of the sealing water replenishing device of the sealing water device for drainage, and Figs. 11 ...

Abstract

The invention aims to prevent not only entering of viruses, insanitary insect pests, an odor or the like, for example, attributed to a shortage of a sealing water in the drain trap, but also contamination, rot, etc., of the sealing water. The sealing water supplying method for the drain trap is for supplying the sealing water to the drain trap of a sanitary fixture using tap water. The water supplying method includes a process of operating a flow passage opening / closing device 30 for opening and closing the flow passage of a water pipe 4m in an exclusive section of an apartment house to keep the flow passage of the water pipe 4m slightly opened, and a process of opening an aqueduct faucet 11s of the sanitary fixture before or after the above-mentioned process to keep the faucet 11s open. Thus, the sealing water in the drain trap is always replaced with a new tap water and a depth of the sealing water is secured.

Description

technical field [0001] The present invention relates to a method for supplying sealing water to a drainage sealing device of a sanitary appliance using tap water, a sealing water replenishment method for a drainage sealing device, a pipeline switch device used in the method, and a sealing device for a drainage sealing device. Water replenishment device. Background technique [0002] As shown in FIG. 13(A) , a sanitary appliance using tap water, such as a washstand, has a substantially U-shaped drainage (drainage) elbow 94 . The sealing water device 94 for drainage is a structure that can store a part of the drainage flowing out from the washstand 92 as sealing water. Under the action of sealing water, polluted air or odor on the downstream side will not be introduced into the drain pipe 93 and the drain pipe 93. Enter the private area. In addition, the condition of the sealed water in the drain water sealing device 94 is such that new drain water is replaced every time the...
