Description

  The present invention relates to a deodorizing compartment structure and a deodorizing toilet unit for storing used clothes, pollutants and the like having odor and humidity.

  Conventionally, various toilets have been proposed as a countermeasure for removing odors drifting in the toilet room. One of the odor removal measures is to install a ventilation fan near the ceiling or top of the closed space of the toilet. In addition, for example, a special deodorant is attached to the toilet body to remove the odor, or a pleasant fragrance. It is well known that a fragrance that emits is contained in a toilet room so as to diminish the unpleasant odor of the toilet.

  The most common deodorization means, which is to install a ventilation fan near the ceiling or upper part of the toilet room and exhaust the odor to the outside, is not a sufficient deodorization measure in relation to the capacity and capacity of the ventilation fan, and the capacity of the ventilation fan is also real In addition, there are problems such as power cost and noise in a large ventilation fan.

  Also, for example, in a nursing home or nursing home, the garments used by residents are collected in one place and separated for washing or disposal depending on the situation. The burden on the staff who are filled with various odors and moisture and who are involved in assistance work is large. In such a case, it is necessary to deodorize the compartment that temporarily stores the used clothes and filth of facilities residents, and to clean the indoor environment such as exhaust, but in such facilities, deodorization of the filth collection room, As countermeasures against exhaust, only measures to provide ordinary ventilation fans on walls or windows are taken.

  As countermeasures for deodorization of conventional household toilets, for example, those disclosed in Patent Documents 1 to 6 other than the installation of a ventilation fan are disclosed. Among them, the ventilation method and the ventilation device of Patent Document 1 is a method of deodorizing by sucking air from a toilet and passing the air containing this odor through the water of a toilet tank. Specifically, an air pump, An odor suction member that sucks air from the toilet and an odor discharge member that sends air from the odor suction member to the water reservoir are used.

  The toilet equipment with an electrostatic atomizer of Patent Document 2 is an apparatus that removes odors and fungi by spraying charged fine particle water in a spray form in the toilet room using the electrostatic atomizer. Further, the toilet deodorization apparatus of Patent Document 3 is provided with an absorbent body in which a catalyst body and an adsorbent are mixed and an oxygen-enriched air generator in the toilet body, and has a catalytic action and an adsorption action of the catalyst body. It is a deodorizing device that requires a special catalyst. The deodorizer of Patent Document 4 is a motor-driven deodorizer, and is a technique for controlling power consumption by controlling the operation time after leaving the toilet according to the length of staying time in a human toilet. In addition, the devices of Patent Documents 5 and 6 are deodorizing devices with a built-in deodorizing agent, and are configured integrally with a built-in blower. It is not a configuration in which clean external air is allowed to flow into the room under a negative pressure state.
