Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method for removing scale from a circulating bathtub and a chemical container for removing the scale.

``Prior art'' For example, as a container for injecting chemicals to remove scale adhering to the inside of a circulating bathtub,
There is one described in No. 53999 (Utility Model Application Publication No. 54-155725).

This container consists of a main part and a neck part, the main part has a body part having a bellows-like part, and a bottom part.At least the neck part can be inserted into a hole in the wall of the bathtub. The neck part is equipped with a discharge valve that can discharge water from inside the container to the outside of the container, and the main part is equipped with a suction valve that can draw air from outside the container into the container.

"Problems to be Solved by the Invention" The container of the prior application is of the so-called bellows pump type, which sucks in the water in the bathtub and pours out the medicine in the container together with the water. bellows-like body,
It requires a discharge valve and a suction valve, and the configuration is complicated.
There was a problem with high production costs.

"Means for Solving the Problems" The present invention has been made to solve the problems of the prior art as described above, and its configuration will be explained below based on the drawings.

First, what is shown in FIG. 1 is a chemical container for descaling a circulating bath pot used in the method of the present invention. A synthetic resin container body 1 each having an injection port 1d having a male screw 1c on its outer periphery, and a synthetic resin container body 1 having a filter element 2a therein and fitted into the injection port 1d of the container body 1. A plug-like tube 2, a synthetic resin cap 3 that closes the outer opening end surface of the plug-like tube 2, a breakable seal 4 provided on the end surface of the spout 1b of the container body 1, and a seal 4 that covers the entire outer periphery. It has a stopper step 5a, a seal-breaking claw 5b in the center of the tip, and a female screw threaded into the male screw 1c of the inlet 1d or the male screw 1a of the spout 1b on the inner periphery of the base. It consists of a synthetic resin truncated conical fitting tube 5 having a screw 5c.

The cap 3 may be connected to the plug-shaped tube 2 through a flexible thin piece as shown in the figure, or be completely separate, or connected to the plug-shaped tube 2 and the flexible tube as shown in FIG. A circumferential groove 3a for pulling is provided on three surfaces of the cap connected via a thin piece, and this circumferential groove 3a
Various types of caps may be used, such as one in which a pulling ring 3b is provided on three surfaces of the inner cap.

Reference numeral 6 denotes a scale removing agent stored in the container body 1, for example, the injection port 1d of the container body 1.
Remove the plug-shaped tube 2 fitted into the inlet 1
It is sufficient to store it in the container body 1 starting from d.

``Operation'' Therefore, in order to remove the scale that has adhered to the inside of the circulating bath pot, the truncated conical fitting tube 5 screwed onto the injection port 1d side of the container body 1 is used.
As shown in FIG. 3, the cap 3 is screwed onto the spout 1b side of the container body 1, and the cap 3 is taken out from the plug-shaped tube 2.

By screwing the truncated conical fitting tube 5 onto the spout 1b side of the container body 1, the seal 4 is broken by the seal breaking claw 5b.

As shown in FIG. 4, a lower opening 8a of the bathtub 8 communicating with the lower pipe 7a of the circulation type bathtub 7 is
The truncated conical fitting cylinder 5, which is one end of the container A, is tightly fitted, and water is poured into the bathtub 8 up to the upper opening 8b of the bathtub 8, which communicates with the upper pipe 7b of the circulation bath pot 7. , Cook the circulating bath pot 7.

Thus, the water in the bathtub 8 flows through the outer opening of the plug-like tube 2 that is the other end of the container A, the filtration element 2a, the container body 1, the truncated conical fitting tube 5 that is one end of the container A, and the lower opening of the bathtub 8. 8a, a lower pipe 7a of the bathtub 7, a circulation path (not shown) inside the bathtub 7, an upper pipe 7b of the bathtub 7, an upper opening 8b of the bathtub 8, and the water in the bathtub 8 is circulated by convection.

The scale removing agent 6 in the container body 1 is dissolved by this convection-circulating water, and the chemical solution reaches the circulation path in the bath pot 7, where it has a peeling effect on the scale adhering to the circulation path. Let's do it.

If the bathtub is stopped from cooking and left as it is, for example overnight, the scale adhering to the circulation path inside the bathtub 7 will be completely removed.

When left unattended, the container A is placed in the lower opening 8a of the bathtub 8.
It may be removed from the

Next, by draining all the water (medicinal solution) in the bathtub 8, the scale in the circulation path in the bathtub 7 is discharged from the lower opening 8a of the bathtub 8.

However, in order to completely discharge the scale in the circulation path in the bathtub 7, it is necessary to insert a hose into the upper pipe 7b of the bathtub 7 from the upper opening 8b of the bathtub 8 and supply tap water. As a result, the scale remaining in the circulation path inside the bathtub is thoroughly washed away.

Note that when washing with tap water, the truncated conical fitting tube 5, which is one end of the container A, is connected to the upper opening 8 of the bathtub 8.
A plug-shaped cylinder 2 that fits tightly into b and serves as the other end of container A.
If the container body 1 is removed from the inlet 1d of the container body 1 and a hose connection port 9 as shown in FIG. 5 is fitted into the inlet 1d, cleaning with tap water becomes convenient.

"Effects of the Invention" As described above, according to the present invention, the spout at one end is provided with a fitting tube, the inlet at the other end is provided with a filtration element,
The fitting tube of the container containing the scale removing agent inside is tightly fitted into the lower opening of the bathtub which communicates with the lower pipe of the circulating bath boiler, and communicates with the upper pipe of the bath boiler. Since the bath pot is filled with water above the upper opening of the bathtub, the scale removing chemical solution in the container can be transferred from the bathtub to the bath pot without using a complicated and expensive bellows pump type container. It can be supplied into the circulation path inside the bathtub by the circulation convection effect.

Moreover, since the fitting tube that fits into the lower opening of the bathtub has a truncated conical shape with a stopper step on the entire outer periphery, it can be tightly fitted into the lower opening of a bathtub of any diameter.

Further, when the fitting tube is screwed onto the spout at one end of the container, the seal of the spout can be broken by the seal wave breaking claw, which is extremely convenient.

Furthermore, since the container has a filtration element in the inlet at the other end, free scale in the bathtub that has been discharged from the upper opening of the bathtub by circulating convection will not be sent back into the bathtub via the container. do not have.
