Abstract

PROBLEM TO BE SOLVED: To provide a washing toilet seat equipped with a drying function, which implements short-period drying by perforating a plurality of injection ports in each of drying nozzles, arranging the drying nozzles at locations laterally symmetrical to a portion to be washed, laterally moving the drying nozzles, switching or opening the injection ports in synchronous movement of the drying nozzles, and blowing water droplets adherent to the buttocks of the user with intermittent injection air. SOLUTION: The washing toilet seat is comprised of a washing water supply means 16 having a washing nozzle 15, an air injecting means 17 for pressurizing and intermittently injecting air from the drying nozzles 19, a drying driving section 20 for driving the drying nozzles 19, and a control section 18 for controlling the means and section. According to the washing toilet seat, the drying nozzles 19 are laterally moved, and intermittently inject the pressurized air from the injection ports during the movement of the drying nozzles in synchronization with the movement of the same. As a result, water droplets adherent not only to the anal portion but also to the surface of the buttocks in a wide range can be removed, and therefore time required for drying can be drastically shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flush toilet seat with a drying function for cleaning the buttocks with warm water and then drying with hot air.

[0002]

2. Description of the Related Art Conventionally, a warm water flush toilet seat of this type for drying an anus part which has become wet by washing after use of stool is, for example, as shown in FIG. Is usually applied to the buttocks to dry.

In FIG. 1, reference numeral 1 denotes a toilet bowl, 2 denotes a cleaning device (not shown), and a warm water flush toilet seat body which has a built-in cleaning nozzle 4 which projects into the toilet bowl 1 to clean the anus of the human body 3.
A toilet seat 5 and a toilet lid 6 are rotatably attached to the main body 2. Reference numeral 7 denotes a drying device built in the main body 2, comprising a blower 8, a heater 9, and a blow duct 10.

[0004] In the above configuration, after the washing nozzle 4 protruding from the inside of the main body 2 so as to be positioned below the anus by a motor or the like in the toilet 1, the heater 9 is turned on by turning on a drying switch (not shown). And the blower 8 is driven, and warm air is supplied from behind the human body to dry the anus. Patently, as described in Japanese Patent No. 625291, a high-pressure air passage is provided in the toilet seat, a plurality of air ejection nozzles are provided in the toilet seat to inject high-pressure air into the anus, or the toilet seat front side In some cases, a nozzle is provided to similarly inject air from the front through a high-pressure air passage in the toilet seat.

[0005]

However, in the above-mentioned conventional structure, the water drop after the anal part washing adheres to the skin and the like around the anal part. Drying is performed by blowing hot air of about 40 ° C, which is blown out. However, the hot air flow stroks the buttocks in the sitting position as shown by arrow A and does not directly hit the anal part. There has been a problem that the time required for almost drying is extremely long, and that the user feels irritated or suffers from a monotonous feeling during use. Further, recently, there is a problem that the skin is over-dried and the skin becomes itchy, rash, etc., because the temperature is forcibly increased and the moisture is evaporated to dry the skin while the skin surface has a large amount of moisture.

On the other hand, the method in which high-pressure air is ejected from the toilet seat is effective in terms of time reduction, but the angle of the nozzle position cannot be freely set with respect to the anus and the area near the center of the anus becomes weak. Satisfactory drying effect cannot be obtained because the distance from the anus is too long and the jet flow is weak, and the production issues such as increasing the pressure resistance of the toilet seat itself and increasing the airtightness are large and the feasibility is poor. It is.

[0007]

According to the present invention, in order to solve the above-mentioned problems, a drying nozzle is disposed substantially symmetrically with respect to a portion to be cleaned, and a plurality of jet ports are sequentially switched or sequentially opened. Is moved intermittently while pressurized air is ejected intermittently.

Accordingly, the high-pressure air sent by the air injection means is intermittently jetted from the drying nozzle having a plurality of jets to the portion to be cleaned, and adheres not only to the anus but also to the surrounding buttocks surface. Since it is possible to reliably remove large water droplets and the like, drying can be surely performed and the time required for drying can be significantly reduced.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 is a cleaning water supply means having a cleaning nozzle for jetting cleaning water toward a portion to be cleaned in a main body including a toilet seat, and intermittently supplying pressurized air. Air drying means having a drying nozzle for injecting air into the nozzle, and the drying nozzle having a plurality of injection ports, and the drying nozzle is disposed substantially symmetrically with respect to the part to be cleaned, so that the air which the drying nozzle intermittently sprays is provided. As a result, pressurized air is intermittently jetted from the almost symmetrical drying nozzle to the part to be cleaned after cleaning, so that large water droplets attached not only to the anus but also to the surrounding buttocks surface can be reliably detected. And the time required for drying can be greatly reduced.

According to the second aspect of the present invention, by sequentially switching the injection ports, first, while intermittently injecting pressurized air, water droplets are blown off from the periphery of the portion to be washed inward so as to be collected at the center. Can be blown off effectively.

According to a third aspect of the present invention, by sequentially opening the injection ports, water droplets are first blown from the periphery of the part to be cleaned to the inside while being intermittently injected with the pressurized air. The central part can be collected and blown off effectively, keeping no water droplets from leaving and returning.

According to a fourth aspect of the present invention, a moving means for moving the drying nozzle in a substantially horizontal direction is provided.
With a small number of jets, the jet air can be more reliably applied to the portion to be cleaned by the movement effect of the drying nozzle, so that water droplets attached to the buttocks can be more effectively blown off.

According to a fifth aspect of the present invention, while the drying nozzle is moved to the center in a substantially horizontal direction, the plurality of injection ports 2 are moved.
6. Pressurized air is injected from 6. Since the movement of the drying nozzle 19 to the center is also added to the jet air, water droplets are more efficiently collected at the center, so that the drying efficiency is improved and the drying time is shortened.

According to a sixth aspect of the present invention, the injection nozzle is sprayed with compressed air from the injection port 26 in synchronization with the movement of the drying nozzle in a substantially horizontal direction, so that the injection nozzle is located at a position where the moisture is best blown off. Since pressurized air can be injected from 26, drying efficiency is improved and drying time is shortened.
