Abstract

PURPOSE:To enable the washing of the seat surface of a toilet seat by providing a splash preventing circumferential wall for surrounding the circumferential periphery of a toilet seat in such a condition that the toilet cover has been closed, and by forming the splash preventing circumferential wall so that the waterdrops coming down along the inner surface of the circumferential wall can be introduced into a toilet bowl. CONSTITUTION:When a toilet cover 3 is brought into a closed condition and washing liquid W is injected through an appropriate number of washing-liquid jetting ports 14 which have been provided on the back surface of the toilet seat 7, the washing liquid is injected against the seating surface 7b of the toilet seat for cleaning the seating surface. Most of the washing liquid after it has cleaned the seating surface flows down along the toilet seat 7 and is intro duced into a toilet bowl 1c. On the other hand, the washing liquid reflected from the seating surface is caught by the back surface of the toilet cover 3 and by a splash preventing circum ferential wall 11 and then flows down along the inner surface of the splash preventing circum ferential wall and is introduced into the toilet bowl 1c. When an appropriate number of hot-air discharge ports 18 are provided on the backside of the toilet seat, the waterdrops of washing liquid attached on the seating surface of the toilet seat can be quickly and forcibly dried by the hot-air discharged through hot-air discharge ports. Further, when the seating surface of the toilet seat is subjected to water repellent finish, waterdrops are hardly attached on the seating surface of the toilet seat, so that the removal of washing liquid can be accelerat ed and the drying time can be shortened.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a Western-style toilet bowl equipped with a seating surface cleaning III for cleaning the seating surface of a toilet seat provided in the toilet bowl.

[Conventional technology]

There is a social demand for Western-style toilets installed in public restrooms that are hygienic and do not feel unclean even when sitting on them. To meet this demand, there is a device that automatically supplies a water-soluble seating sheet onto the seating surface of a toilet seat.

[Problem to be solved by the invention]

However, the seating sheet feeding device has the following drawbacks. (a) It does not make the toilet seat itself W4 clean. Therefore, when the toilet seat is dirty, even if a seating sheet is supplied to the seating surface of the dirty toilet seat, the feeling of uncleanness cannot be completely eliminated. (1)) When the seat is missing, it cannot perform its original function. (Since the C1 seat has a special shape with a cutting line that corresponds to the opening of the toilet seat, it lacks versatility. [dl If the seat is expensive, running costs will increase. In order to solve the above-mentioned drawbacks, the present invention aims to provide a Western-style toilet bowl with a seating surface cleaning device that can clean the seating surface of the toilet seat.

[Means for Solving the Problems] The means adopted by the present invention to solve the above problems is that in a Western-style toilet equipped with a toilet seat and a toilet lid that can be opened and closed, the toilet lid has a seat on the back side of the toilet lid body. An appropriate number of cleaning liquid spouts are provided to spray onto the seating surface of the toilet seat when the toilet lid is closed. A peripheral wall is provided, and the scattering prevention peripheral wall is formed to guide water droplets traveling along the inner surface of the peripheral wall into the toilet bowl. In order to strongly dry water droplets adhering to the seating surface of the toilet seat, the toilet lid has an appropriate number of hot air discharge ports on the back side of the toilet bowl body that discharge hot air onto the seating surface of the toilet seat when the toilet lid is closed. may be provided. Furthermore, in order to make it difficult for water droplets to adhere to the seating surface of the toilet seat, the seating surface of the toilet seat may be treated with a water-repellent surface. [Function 1] When the toilet lid is opened and cleaning liquid is sprayed from an appropriate number of cleaning liquid spouts provided on the back side of the toilet seat, the cleaning liquid is sprayed onto the seating surface of the toilet seat and cleans the seating surface. Most of the cleaning liquid that cleans the seating surface passes through the toilet seat and is led into the toilet bowl. On the other hand, the cleaning liquid reflected from the seating surface is captured by the back surface of the toilet lid and the anti-scattering wall, and is guided into the toilet bowl along the inner surface of the anti-scattering wall. The seating surface of the toilet seat is cleaned with the sprayed cleaning liquid, making it a sanitary surface free from dirt. If an appropriate number of hot air D1 outlets are installed on the back side of the toilet seat,
The water droplets of the cleaning liquid adhering to the seating surface of the toilet seat can be quickly and forcefully dried using the warm air discharged from the hot air outlet. Furthermore, when the seating surface of the toilet seat is treated as a water-repellent surface,
Water droplets are less likely to adhere to the seating surface of the toilet seat, the cleaning liquid drains easily, and the drying time can be dramatically shortened.
