Abstract

PURPOSE:To prevent stink from exhalation by scattering foam produced by foaming agent on the surface of water stored previously in a stool basin to embed excrement in the foam. CONSTITUTION:A nozzle is provided projectingly in a required position of a stool, for example a position deep from below a hip seating section of stool seat 4 to afford communication between the proximal end of the nozzle 8 and a foam generator M. Also in the generator M, for example, an air sol type enclosed cylinder 9 is filled with incombustible liquefied gas in which is mixed chemicals foaming in reaction with water. An operation section provided in a generator case is operated to produce foam on the surface of water to shorten as short as possible a time taken for contact of excrement with air in excretion, so that stink can be prevented from exhalation.

Description

[Detailed description of the invention] (b) Industrial application fields This invention relates to a deodorizing toilet bowl.

(B) Conventional technology There are various methods for deodorizing toilet bowls, but most of them are to efficiently exhaust odors using an exhaust device (Japanese Patent Application Laid-open No. 30736/1983). . Such an exhaust device has an intake part and an exhaust part at a predetermined position of the toilet bowl.

In addition to these, various techniques have been considered for countermeasures such as hiding the odor during defecation with an air curtain or adding a deodorizing agent.

(c) Problems to be solved by the invention However, each technology has its own advantages and disadvantages, and the reality is that it is difficult to easily popularize them.

Therefore, in this invention, without making any structural changes to the toilet bowl structure itself for deodorization, we attempted to efficiently deodorize by using foaming to promote denaturation of odors or by enclosing odors.

(d) Means for Solving the Problems The present invention aims to provide a deodorizing toilet comprising a toilet bowl in which foam made of a foaming agent is sprayed onto the water storage surface within the toilet bowl.

(E) Functions and Effects According to the present invention, since the foam made of the foaming agent is sprayed on the water storage surface of the toilet bowl in advance, the following effects can be achieved.

■If the dirt is buried in the foam, it will cover the odor and prevent the odor from escaping.

■Since it is a foam, it is possible to completely cover the waste and suppress the release of odors.

■In order to spray on the water storage surface, the water seal level can be brought as high as possible with foam, and the time that filth comes into contact with the air during defecation is minimized to prevent the release of odors. can be done.

■The mechanism that generates bubbles is structurally simpler than the deodorizing mechanism that uses water or spray water, and is easier to install on the toilet bowl.

■Since the foam-generating container can be equipped with the drug in the state before foaming, the container can be as small as possible, and it can be used easily by refilling the drug or replacing the container, making it economical. Targeted and easy to use.

■Water is not used for deodorizing, so it helps save water.

■It is easy to mix aromatics into the foam, color it, etc.
In addition to deodorizing efficiency, various conveniences can be obtained.

■Since foam is generated on the water storage surface, filth does not fall directly onto the water surface during defecation, and the foam acts as a buffer, preventing so-called change.

(F) Embodiment An embodiment of the present invention will be described in detail based on the drawings. Fig. 1 shows a deodorizing toilet bowl of the present invention. A water tank 2 is installed above one end of the toilet bowl 1, and a water tank 2 is installed above one end of the toilet bowl 1. A communication path is formed from the drain valve of the tank 2 to supply water to the toilet bowl.

Toilet 1 has a seat with a flag that can be used for both urination and urination.
A toilet seat 4 is connected to the periphery of the toilet bowl 3 in a manner that allows it to rise and fall freely.
A toilet lid 5 is also provided above the toilet seat 4 so as to be openable and closable as required.

A hollow rim 6 is provided around the periphery of the toilet bowl 3 to allow flushing water to pass through.
A large number of water injection holes 7 are provided on the bottom surface of the hollow rim 6, so that the inner peripheral wall surface of the toilet bowl 3 can be washed with the flushing water from the toilet bowl 3. Water is supplied from required locations below the rim 6 and is configured to be stored in the toilet bowl 3 while maintaining a constant water level.

The gist of the present invention is to configure such a toilet bowl so that foam caused by a foaming agent is not dispersed on the water storage surface W within the toilet bowl.

That is, the nozzle 8 is provided protrudingly at a desired position on the toilet bowl, for example, at a position deeper than the bottom resting part of the toilet seat 4, for example, at a side position of the toilet bowl 3 below the hollow rim 6. It is inserted through the inner circumferential wall of the toilet bowl 3 and has its base end protruding outward.

The base end of the nozzle 8 is communicated with a foam generator M installed outside the toilet bowl.

Regarding the bubble generator M, as shown in Fig. 2, an aerosol type sealed cylinder 9 is used as the generator, and the cylinder 9 is filled with nonflammable liquefied gas. It is also possible to mix into the gas a chemical that foams when it reacts with water, and it is also possible to spray it from the nozzle 8 by using a highly volatile liquefied gas without mixing any chemicals. It can also be made to foam when sprayed into water. In addition to the aerosol type described above, it is also possible to fill the foam generator M with a foaming liquid and eject the same liquid from the nozzle 8 to generate foam F on the water storage surface W.

Such a foam generator M is provided with an operating section m near the toilet bowl or on the generator case, and by operating the operating section, a button on the cylinder of the generator can be pressed or a blowout mechanism provided on the generator can be operated. It can be configured as follows.

In addition to manually operating the operating section, it is also possible to automatically detect that a person is seated and operate the bubble generator M to generate bubbles on the water surface.

Furthermore, as shown in FIG. 3, instead of using the foam generator M having the above-described structure, an effervescent tablet F1 that can react with water to generate foam is introduced or introduced into the toilet bowl. A mechanism capable of foaming may also be provided.

That is, a vibrator 10 having a delivery port 10a is installed in a part of the inner circumferential wall of the toilet bowl, the base end of the pipe 10 is communicated with the tablet storage section 11, and a tablet pressing piston 10' is inserted into the pipe lo. By operating a push button, the tablets F1 are inserted into the toilet bowl 3 one by one through the pipe 10, and the tablets F1 that are inserted react with the water to generate bubbles on the water surface. It turns out.

Regarding the bubbles formed here, try to form as many large bubbles as possible, and the bubbles formed on the water storage surface will rise to a higher position than the water storage surface, and during defecation. The distance between the butt and the butt is kept as short as possible to reduce the amount of odor emitted. Furthermore, the state in which the bubbles are raised all over can also prevent the occurrence of change during defecation.

The nozzle or tablet feeding pipe 10 communicating with the foam generator M mentioned above is arranged at a predetermined position below the hollow rim to prevent dirt from adhering during defecation, but if necessary,
It is also possible to make it extendable and extend it into the toilet bowl only when bubbles are generated.

Note that the foam F generated once is discharged together with filth when the water stored in the toilet bowl 3 is discharged, but after defecation is completed, an antifoaming agent is supplied separately to eliminate the foam and drain it out along with the stored water. It is also possible to do so.

In FIG. 2, a hollow rim 6 is shown for supplying such defoaming agent.
A defoaming agent supply passage 11' is formed therein, and the defoaming agent is supplied to the passage 11' and is ejected from an antifoaming agent nozzle 12 connected to the road 11'.

In this case, a foam extinguishing agent storage container is separately provided in the foam generator, and the foam extinguishing agent is spouted from the container through a nozzle.

The embodiment of the present invention is configured as described above, and the bubbles formed on the water storage surface prevent the emission of odors of filth as much as possible, and also have the effect of preventing change.
It is possible to provide an effective deodorizing toilet bowl with a relatively simple structure.
