Abstract

PROBLEM TO BE SOLVED: To provide a method capable of eliminating stagnant water in the bottom of a toilet with very simple work. SOLUTION: When stagnant water 16 of a drainage trap in the bottom of a toilet 10 is eliminated, a suction pipe 22 is immersed into the stagnant water 16 by using a hand pump 20 having the suction pipe 22 and a discharge pipe 24 and, at the same time, the discharge pipe 24 is located at a drain pipe side. The stagnant water 16 pumped up through the suction pipe 22 discharged to a drain pipe 18 from the discharge pipe.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing accumulated water from a drain trap of a plumbing device such as a toilet.

[0002]

2. Description of the Related Art A drain trap is provided at the bottom of a toilet to prevent odor from flowing backward from a drain pipe on the downstream side. This drain trap shuts off the drainage path of sewage by holding the stored water (sealing water). However, when cleaning the bottom of the toilet, in other cases, for example, the installation site for the already installed toilet In some cases, it may be necessary to remove stored water when applying an antifouling agent to the toilet bowl surface.

[0003] As a method of removing the water retained in the drain trap, a container such as a bucket is generally placed in a toilet room,
Then, a method is adopted in which the suction pipe of the hand pump is inserted into the pool water of the drain trap, the pool water is pumped up, and discharged to a container such as a bucket in the toilet room.

[0004]

However, in this case, it is necessary to prepare a container such as a bucket, bring it into the toilet room, and place it on the floor near the toilet bowl, etc., and the accumulated water pumped into the bucket or the like. Must be transported to another location and discarded.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve such problems. Claim 1
Is a method of removing the retained water of a drain trap, using a pump having a suction pipe and a discharge pipe, immersing the suction pipe in the stored water and moving the discharge pipe to the drain pipe side. And discharging the stored water pumped through the suction pipe from the discharge pipe to the drain pipe.

According to a second aspect of the present invention, there is provided a method for removing stored water according to the first aspect, wherein the pump is formed by shortening the suction pipe by a predetermined length from the discharge pipe. I do.

The method for removing stored water according to claim 3 is based on claims 1 and 2.
Wherein the drain trap is a drain trap at the bottom of a toilet bowl.

[0008]

As described above, the present invention uses a pump having a suction pipe and a discharge pipe when removing the water retained in the drain trap, and positions the discharge pipe on the drain pipe side to remove the suction water. Retained water pumped through a pipe is discharged from the discharge pipe to the drain pipe side.In the case of this method of removing the stored water, the stored water is directly discharged to the outside through the drain pipe. It is not necessary to perform a troublesome operation such as placing a container, taking out the stored water there, and then taking the stored water to another place and throwing it away, and the stored water can be easily removed.

In the present invention, it is advantageous to use a pump in which the suction pipe is shorter than the discharge pipe by a predetermined length as the pump (claim 2). By doing so, the discharge pipe of the pump can be inserted deeply into the drain pipe side,
Removal of stored water can be performed more easily.

The present invention can be applied to the removal of water from various plumbing sanitary devices having a drain trap, and is particularly suitable as a method for removing the water from a drain trap at the bottom of a toilet bowl. (Claim 3).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 10 denotes a Western-style toilet, 12 denotes a pot, and 14 denotes a drain trap at the bottom of the pot 12. The drain trap 14 holds stored water (sealed water) 16. A drain pipe 18 is connected to the drain trap 14, and sewage from the pot 12 is discharged to the outside through the drain pipe 18 through the drain trap 14.

Reference numeral 20 denotes a hand push pump, which has a suction pipe 22, a discharge pipe 24, and a hand push operation section 26 as shown in detail in FIG. The hand pump 20 includes a pair of check valves 28 and 3 on a path from the suction pipe 22 to the discharge pipe 24.
0 is provided.

In the hand pump 20 of this embodiment, the suction pipe 22 is shorter than the discharge pipe 24 by a predetermined length L. In this example, it is desirable that L is set to 25 cm or more. The hand pump 20 can be easily obtained by cutting a suction pipe 22 of a normal hand pump used for pumping kerosene or the like at a predetermined position.

FIG. 1 shows a water pump 1 using this hand pump 20.
6 specifically illustrates a method of removing 6. As shown in the figure, in the method of this embodiment, the suction pipe 22 of the hand pump 20 is inserted into the reservoir 16 of the drain trap 14 so that the lower end is located at the bottom of the drain trap 14, and the discharge pipe 24 is It is inserted deeply into the drain pipe 18, and its tip is connected to, for example, a wear portion (overflow portion) 32 of the drain trap 14.
Keep it near.

In this state, when the manual push operation section 26 is manually pushed, the stored water 16 pumped up through the suction pipe 22 is drained to the drain pipe 18 through the discharge pipe 24. Therefore, the drainage trap 1 is repeatedly operated by the hand pressing operation section 26 repeatedly.
4 can be discharged to the outside through a drain pipe 18 and removed from the drain trap 14.

According to the stored water removing method of this embodiment, a container such as a bucket is placed in the toilet room, and the stored water 16 is taken out there.
Further, it is not necessary to perform a troublesome operation such as bringing the stored water 16 to another place and throwing it away, and the stored water 16 can be easily removed.

In this embodiment, since the suction pump 22 is shorter than the discharge pipe 24 by a predetermined length as the hand pump 20, the discharge pipe 24 of the hand pump 20 is inserted deeply into the drain pipe 18 side. Therefore, the removal of the stored water 16 can be performed more easily.

Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention can also be applied to a Western-style toilet other than the above-mentioned embodiment or another plumbing sanitary having a drain trap. The present invention can be configured in variously modified forms without departing from the gist of the invention, such as using an electric pump or another form of pump as the pump.
