Abstract

PURPOSE:To clean safely with high efficiency by a method wherein the suction port of the bath boiler, communicated with a bathtub, is closed tightly and detachably, while self-foaming type cleaning agent is solved into water at the inside of the suction port and the cleaning agent is foamed and diffused under isolating the boiler from the bathtub. CONSTITUTION:The self-foaming type cleaning agent, solved, foamed and diffused by water, is sealed into a cartridge type vessel and the opening end of the vessel is sealed tightly by the film of soluble high polymer resin. The opening of the vessel 13 is opened and is inserted into the suction port 2 of the bath boiler tightly. The cleaning agent A is solved and foamed when it is contacted with water and, at the same time, it is diffused and bubbles of carbon dioxide or the like move upward along the inner wall of the boiler through narrow spaces slowly to soften and resolve scale, sludge or the like adhered to and accumulated on the wall. Such condition is continued for a predetermined period of time and, thereafter, the vessel 13 is removed. Then, water is poured through a hose to wash the scale or the like out of the suction port or a discharging port. According to this method, the bath boiler may be washed efficiently, safely and inexpensively.

Description

[Detailed Description of the Invention] Fields of Application This invention can be used in the field for household or commercial use to remove hot water scale and dirt deposited on the inner walls of bathtubs. .

PRIOR TECHNOLOGY The inner wall of the bathtub, on which hot water scale and slime are deposited, is a quiet and quiet area where cleaning tools are inserted, so it is very difficult to clean and remove them. method has been proposed.

A representative example of this is the application filed by the applicant (Utility Model No. 57
-115668), but this spray method uses a surfactant.

A can container is filled with alkaline bilge or the like together with LP gas or chlorofluorocarbon gas, and the spraying part is pressed against the water intake port of the bathtub to spray the water.

However, with this spray method, the gas uffiW power is used to blow away and clean dirt such as dirt that adheres to the inside of the bathtub, but the sprayed cleaning agent is not used in the bathtub. As the water passes through the tank and flows into the bathtub all at once, the water in the bathtub also flows in from the water intake port, which inevitably dilutes the inside of the pot and impairs the cleaning effect.Furthermore, flammable LP gas is used. In this case, there was a risk of ignition and other safety issues.

There is also a cleaning method in which a hand-pump type plastic container is filled with powdered detergent and inserted into the water intake of the bathtub along with running water to oxidize and decompose the dirt inside the cup. The method uses a manual pusher (1lkf'11:), which makes it difficult to work and difficult to operate, and is the same as the previous spray method in that the water in the bathtub flows in from the water intake and is diluted. And safety 1! A method that can actually perform cleaning has been long awaited.

Purpose of the Invention The present invention has been made to completely solve these conventional problems, and its first purpose is to easily and reliably eliminate the need for spraying or inserting detergent using a hand pump. The purpose of the present invention is to provide a method for effectively cleaning the inside of a bathtub and a device for directly carrying out the method.Another purpose is to seal the water intake port of the bathtub to isolate the inside of the bathtub from the bathtub. The object of the present invention is to provide a method and apparatus that can perform cleaning with high efficiency by foaming and diffusing a cleaning agent in a high-density condition that prevents water from the bathtub from flowing into the inside of the pot from the water intake port. Yet another object is to provide this type of method and apparatus that are highly safe and do not use flammable gas such as LP gas.

Structure The purpose of this is to removably seal the water inlet of the bath kettle that communicates with the inside of the bathtub with a closure such as a stopper or a lid, and dissolve a self-foaming cleaning agent in water in the sealed water inlet. The cleaning agent is foamed and diffused under a shield 6 that connects the interior and the bathtub part, and a cartridge-type container that is removably tightly fitted into the water intake port of the bathtub that communicates with the inside of the bathtub is provided when it gets wet with water. This can be achieved by enclosing a self-foaming cleaning agent that dissolves under water pressure and foams and diffuses, and sealing the open end with a coating of water-soluble polymer resin.

Examples Example 1゜The main ingredients are a self-foaming agent, a surfactant, and a tablet or tablet. Chop it into granules and make it into self-foaming cleaning agent A.

This cleaning agent A is applied to the water intake port 2 of the bath pot 1 as shown in FIG.
The opening is sealed with a stopper or lid 3 made of material such as sponge, rubber, or plastic.

In this way, communication between the bathtub portion 4 and the bathtub 1 through the water intake port 2 is completely cut off.

When cleaning agent A gets wet with water, the cleaning ingredients dissolve in the water, foam, and at the same time diffuse, causing carbon dioxide and other gas bubbles to quietly move up along the wall inside the pot, which is a narrow space that is blocked from communicating with the inside of the bathtub. It comes into contact with adherent substances such as hot water scale and #j mud that have accumulated on the wall and acts to soften and melt them. Some of the dissolved dirt gradually floats up with air bubbles and flows out into the bathtub 4 from the outlet 5, but some of it settles and stays at the bottom. This state of confusion is maintained until a predetermined period of time has elapsed, and then [i3 is removed. Then, tap water or the like is flowed in through the water intake port or drain port with a hose to wash it away.

Practical Example 2 As shown in Figure 2, the stopper or lid is attached to a cartridge type container 13.
The above-mentioned detergent A is filled into tablets or granules. The mouth of this container 13 is opened and i+17 is fitted into the water intake port 2 of the bathtub.

The inside of the container 13 communicates with the inside of the pot and is washed immediately. 11A dissolves in water and foams and diffuses.

Example 3 As shown in FIG.
It is filled with p-agent A and provided with a coating film 6 of water-soluble polymer resin at the open end. # of this water-soluble polymer resin
It is assumed that the membrane 6 does not dissolve immediately when immersed in water, but dissolves after a certain period of time and water enters the container 23. Therefore, if this solution is inserted into the water intake port 2 of the bathtub and left in place, the coating 6 will melt after a predetermined period of time and open the mouth of the container, thereby delaying the foaming and diffusion of the detergent A. I can do it.

Next, an example of the formulation of cleaning agent A will be given.

Formulation example 1 (Composition) (Parts) Sodium carbonate Citric acid (anhydrous) 20 Sodium percarbonate 59 Sodium alkylbenzenesulfonate 1 Formulation example 2 (Composition) (Parts) Sodium hydrogen carbonate Beautiful citric acid Sodium persulfate 39 α-olefin Sodium sulfonate 1 The products obtained in Prescription Method Examples 1 and 2 are made into tablets or granules,
These tablets or granules were also externally coated with polyvinylpyrrolidone in the case of Formulation Example 1 and with methylcellulose in the case of Formulation Example 2. make something.

Externally coated detergent 1p formulation A was prepared in Examples 1 and 2 above.
When used in the water, foam diffusion can be delayed until the coating gets wet and dissolves.

Effects of the Invention In ordinary domestic baths, the amount of hot water remaining in the bathtub after bathing is on average about 100 to 200 liters (1), while the capacity inside the bath pot is thought to be about 21 liters (1). In this case, if you clean the bathtub with the water intake port open, the water in the bathtub will circulate through the inside of the pot and be diluted according to the principle of the communication pipe, so the cleaning effect will be between 00 and 200 centimeters. The IIC becomes 1/1, that is, 50 to 100 minutes.

In the present invention, the bathtub part and the water intake port of the bathtub are sealed with a stopper, a lid, or other closing body, and a self-foaming PP detergent is dissolved in water and foamed and diffused in the corridor where communication is cut off. This allows for high-density cleaning, and since the water on the bathtub side does not flow into the pot through the water intake, the cleaning effect is not impaired by dilution as in conventional methods, and cleaning can be performed reliably and efficiently. . In addition, it does not use flammable gas such as LP gas, so there is no danger of ignition or explosion, making it highly safe.Furthermore, it does not require the troublesome operation of a hand pump, making it the #1 product to handle. It has excellent effects such as ease of use, simple configuration, and low-cost VC implementation.
