JP2007330372A - Deodorization method and deodorization apparatus for western style toilet, care toilet and cat toilet - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a chemical deodorization method in order to keep a comfortable living environment by sucking and removing odor components generated from filth although the odor components are reduced by the certain amount of treatment in the present condition but the present condition is not satisfiable yet for a Western style toilet, a care toilet and a cat toilet. <P>SOLUTION: The odor of the filth generated from the Western style toilet, the care toilet and the cat toilet is sucked by an air pump or the like and bubbled in an aqueous solution composed of the combination of an oxygen-based oxidizing agent and organic acid or ventilated to a packing adsorbed to carbon granules, the sulfur compound and nitrogenous compound of the odor components are chemically fixed and prevented from being released in a room, and deodorization treatment is performed. The electricity using amount of the air pump is little and burden is economically small. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

The present invention eliminates the odor of filth generated in Western-style toilets, nursing toilets, cat toilets, etc. by passing it through an oxygen-containing oxidant and a deodorizing liquid composed of an organic acid aqueous solution, This is a method and apparatus for deodorizing by ventilating a packing in which an organic acid is adsorbed on a carrier.

In rooms using Western-style toilets, nursing toilets, and cat toilets, the actual situation is that they are uncomfortable with the small amount of odor components that are generated from the toilet during standby, as well as during normal use of the toilet. The present invention is a deodorization technique for solving these odor problems and maintaining a comfortable living environment.

In Western-style toilets, even if filth is flushed with water after use, odors from excretions remain in the toilet bowl, and the next user usually feels uncomfortable.
Since the nursing toilet cannot be washed with water, it may generate odors regardless of whether it is in use or on standby, and an unpleasant odor will remain in the room. Cat litter mixes deodorant components with cat sand to suppress the generation of odors, but some odor components diffuse into the room.

In a Western style toilet, the deodorant component can be dissolved in flush water as in Patent Document 1 to fix the odor in the liquid, but the odor component in the toilet is diffused in the air. Patent Document 2 discloses a method of spraying a deodorizing liquid into a toilet bowl, but there is a problem that splashes adhere to the body when the deodorant liquid is applied to the toilet seat.

It is to establish a deodorizing method for treating odor generated from filth without taking it into the room regardless of whether it is in use or waiting in a Western-style toilet, nursing toilet and cat toilet.

Odor components are mainly sulfur-based hydrogen sulfide, mercaptans and nitrogen-based ammonia, and methylamines, so each is passed through an aqueous solution of hydrogen peroxide and citric acid, and chemically reacted to remove odor components. I can do it.

  As a result of the actual test in the Western-style toilet or the nursing toilet, no odor was felt at all. In a cat toilet, it was difficult to achieve perfection due to the shape of the opening, but the effect was sufficient.

Western style toilets are free of filth after washing, so there is no odor in about 10 minutes after use, and there is no effect even if the air pump is stopped. Need to operate the pump.

Table 1 shows the results of measuring the air in the toilet bowl in use or waiting in a Western-style toilet for each location of the flow in FIG.
The suction capacity of the air pump was deodorized by bubbling in 800 ml of deodorizing liquid using air stone at 1.0 L / min.

Table 1 shows the results of measuring the air in the toilet in use or waiting in the nursing toilet for each location of the flow in Figure 1 under the condition that the deodorant solution is used as it is.
The suction capacity of the air pump and other conditions are the same as in Example 1.

The air in the toilet bowl in use or waiting in a Western-style toilet was aerated and adsorbed through a packing in which the deodorizing liquid was absorbed in granular charcoal. The result was the same numerical value as in Example 1, and it was confirmed that it could be processed effectively.
The suction capacity of the blower was 1.0 L / min, and the packed tower used a glass tube of 40 mmΦ × 200 mm (packing part) H. The granular charcoal used was a 6Φ × 10H cylindrical shape with 45 g of 2% hydrogen peroxide solution and 1.0% citric acid absorbed per 100 g.

The air in the toilet in use / standby of the nursing toilet was adsorbed by aeration in a packing made by absorbing the deodorant liquid into granular charcoal and drying it. The result was the same numerical value as in Example 2, and it was confirmed that it could be processed effectively.
The suction capacity of the air pump and other conditions are the same as in Example 3.

Filling with the absorption bottle of 4 or 5 of deodorant absorbed in the deodorant liquid by sucking the air in the toilet with 3 air pumps from the space of 1 nursing toilet or 2 western toilet By ventilating the tower, odorous components are removed and no bromide.
