Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to flush toilets for toilets in hotels and the like, where there are particularly strong demands regarding deodorization and hygiene management.

Conventional technology Most toilets installed in hotels are equipped with a seat-type flush toilet (hereinafter referred to as a Western-style flush toilet), but Western-style flush toilets have problems in hygiene management regarding cleaning and disinfection of the toilet seat. Therefore, it is extremely difficult to keep the toilet seat clean at all times. In many cases, Western-style flush toilets in hotels and the like are provided with toilet seat covering paper, but the use of toilet seat covering paper is extremely cumbersome and is disliked by users, especially clumsy users. There are various proposals regarding the equipment necessary to completely eliminate the above problems, but the structures of these proposals are quite complex and there are few practical products. Considering this point, the advantage of Japanese-style flush toilets that do not allow the skin to come into direct contact with the toilet bowl becomes apparent, and it may be possible to install Japanese-style flush toilets in place of Western-style flush toilets.

Problems to be Solved by the Invention Although Japanese-style flush toilets are superior to Western-style flush toilets in terms of hygiene, they are inferior to Western-style flush toilets in their ability to block the odor of filth. This is because there is a difference in the odor transport and discharge function of the wash water that flows through the odor-preventing trap that prevents the odor from the drain pipe from entering the toilet room. In the case of Western-style flush toilets, not only is the amount of flushing water in the trap large, but the shape of the toilet bowl is such that the flow of flushing water is accompanied by a swirl that contributes to the discharge of odors. (In the case of Japanese-style flush toilets, the fact that the odor blocking function is inferior to that of Western-style flush toilets can be said to be a major drawback of Japanese-style flush toilets.) The main body of the ceramic Japanese-style flush toilet, which has a shape that causes a swirl in the horizontal plane to accompany the flow of flushing water inside the toilet, is supported by a metal plate case with the top surface of the toilet bowl placed in a position lowered from the floor surface of the toilet room. A wide footrest pedestal with a filth drop opening in the center having a width approximately equal to the opening width of the toilet bowl of a normal Japanese-style flush toilet is placed above the toilet bowl of the ceramic Japanese-style flush toilet body. It is characterized by

Here, the term "jet siphon deodorizing trap" refers to a deodorizing trap that has a jet generating part that promotes the siphon effect. Note that jet siphon type deodorizing traps are installed in most Western-style flush toilets and some Japanese-style flush toilets.

Function The flush toilet according to the present invention has a wide footrest provided at the top of the toilet, which serves as an element to keep the user's posture stable when using the toilet, and the posture is similar to that of conventional Japanese-style flush toilets. The toilet bowl is designed to be used to defecate, and the toilet bowl itself is supported by a metal plate case with the top surface of the toilet bowl lowered from the floor of the toilet room. By changing the support position of the toilet bowl body on the toilet floor, a swirl that contributes to the removal of odors is generated in the toilet bowl in the same way as in conventional Western-style flush toilets. .

Embodiment FIG. 1 is a longitudinal sectional side view showing an example of a Japanese-style flush toilet according to the present invention, FIG. 2 is a plan view thereof, and FIGS.
FIG. 3 is a cross-sectional view taken in the − direction.

In these figures, 1 is a ceramic Japanese-style flush toilet body, 2 is a metal plate case, and 3 is a wide footrest. A Japanese-style flush toilet main body 1 and a footrest pedestal 3 are positioned and supported by a metal plate case 2. The top surface of the toilet bowl 4 of the Japanese-style flush toilet main body 1 is set at a position lower than the floor 5 of the toilet room, and a wide footrest pedestal 3 is placed on top of the top surface of the toilet bowl 4.

As shown in Figure 2, the footrest pedestal 3 is a wide element with a width approximately equal to the width of the toilet bowl (190 mm to 200 mm) in a normal Japanese-style flush toilet.
A waste dropping port 6 with W ₀ is provided. The top surface position of the footrest pedestal 3 is made to match the top surface value of the floor 5. FIG. 3 shows the toilet bowl width increased by the intervention of the footrest pedestal 3. The increased width of the toilet bowl is shown in FIG. 4 with the reference numeral _W1 .

7 is the deodorizing trap, and 8 is the water sealing level of the deodorizing trap. The deodorizing trap 7 is of a jet siphon type and has a cleaning water spout 9. Reference numeral 10 denotes a cleaning hole for eliminating clogging of the deodorizing trap 7, which is normally blocked off from the outside world by an embolus 11. Reference numeral 12 denotes a water closet cover that covers the water closet 13 of the toilet bowl main body 1. Both the toilet bowl cover 12 and the wide footrest pedestal 3, which serve as exterior members of the toilet bowl, are made of decorative materials and contribute to making the toilet bowl more luxurious.

The metal plate case 2 is provided with a connection part 14 to a water supply pipe and a connection part 15 to a drain pipe, and is also provided with a backup mechanism (slack removal mechanism) 16 for the toilet main body 1.

Effects of the Invention The present invention provides a Japanese-style flush toilet that has the same deodorizing effect as a Western-style flush toilet and does not have the problems of sanitary management regarding cleaning and disinfection of the toilet seat unlike the Western-style flush toilet.
