Description

  The present invention relates to a flush toilet, and more particularly, to an apparatus for sterilizing pool water in a bowl portion of an toilet using an ultrasonic generator such as an ultrasonic vibrator.

  In general, a flush toilet is provided with a drainage channel communicating with the trap part at the bottom of the bowl part, and normally collects water from the bottom part of the bowl part to a predetermined height position. It is configured to drain together.

  And in this kind of flush toilet, it is known to sterilize the pool water in a bowl part normally using ultrasonic generators, such as an ultrasonic vibrator (refer to patent documents 1). This is an ultrasonic generator that generates ultrasonic vibrations in the accumulated water and generates cavitation, thereby exhibiting a sterilizing effect.

Patent Document 1 describes three configurations as a configuration in which an ultrasonic generator is installed in a flush toilet. That is,
(1) An ultrasonic generator is installed in the pooled water inside the bottom of the bowl portion, and is configured to cause ultrasonic vibration directly to the pooled water in the bowl portion with the ultrasonic generator at normal times.
(2) An ultrasonic generator is installed on the outside of the wall surface of the bowl portion, and is configured to cause ultrasonic vibration to the accumulated water in the bowl portion through the wall surface of the bowl portion with the ultrasonic generator at normal times.
(3) An ultrasonic generator is installed so that it can be taken in and out of the pool water in the bowl, so that the ultrasonic generator is ultrasonically vibrated with respect to the water in the bowl while the ultrasonic generator is placed in the water in the bowl at normal times. Configure.

Japanese Patent Laid-Open No. 11-293752

  However, in the case of the configuration (1) among the above three configurations, the ultrasonic generator is installed in the pool water inside the bottom of the bowl portion, so that the ultrasonic generator hinders drainage during drainage. There's a problem.

  In the case of the configuration (2), since the ultrasonic generator generates ultrasonic vibrations with respect to the water stored in the bowl through the wall of the bowl, a high-power ultrasonic generator is used. There is a problem that the manufacturing cost is increased accordingly. In particular, when the bowl portion is made of earthenware, the above-mentioned problem is remarkable because the thickness of the bowl portion is relatively thick and the transmission rate of ultrasonic vibration is low.

  Furthermore, in the case of the configuration (3), a driving device for taking the ultrasonic generator into and out of the pool water in the bowl portion is required in addition to the ultrasonic generator, which increases the number of parts. There are problems such as high manufacturing costs.

  In view of such various points, the present invention aims to provide a high-output ultrasonic generator by improving its configuration, particularly when an ultrasonic generator is provided in a flush toilet equipped with a ceramic bowl. Even if it is not used, ultrasonic vibrations can be reliably generated with respect to the accumulated water in the bowl portion. Accordingly, it is an object of the present invention to provide a flush toilet that can reduce the manufacturing cost and that the ultrasonic generator is unlikely to interfere with drainage during drainage, and that can effectively and effectively sterilize pool water.

  In order to solve the above-described problems, the present invention is premised on a flush toilet configured to store water from a bottom of a bowl part to a predetermined height position. And the said bowl part is comprised with earthenware, The through-hole which penetrates the inside and outside of the said bowl part is provided in the lower part below the water surface of the said pool water of this bowl part, and an output part is provided in this through-hole. An ultrasonic generator is provided. The output part of the ultrasonic generator is exposed inside the bowl part. The ultrasonic generator sterilizes the pool water by causing ultrasonic vibration to the pool water.

  According to the flush toilet of the present invention, a through hole is provided in a lower part of a ceramic bowl part, and the output part of the ultrasonic generator provided in the through hole is exposed to the inside of the bowl part, It is designed to cause ultrasonic vibrations in the reservoir water. For this reason, even if it does not use a high output ultrasonic generator, an ultrasonic vibration can be reliably produced with respect to the pool water in a bowl part, and it is hard for an ultrasonic generator to obstruct drainage at the time of drainage. Therefore, it is possible to reliably and effectively carry out the sterilization of the stored water while reducing the manufacturing cost.
