Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flush toilet bowl. More specifically, the present invention relates to a flush toilet bowl which prevents dirt from adhering to the bowl surface of the toilet bowl and enables use in a clean state.

[0002]

2. Description of the Related Art Up until now, there have been known stool-type flush toilets having various designs and structures. These flush toilets are, for example, a siphon type, depending on the type of waste and flush water discharged after use. Siphon jet type, siphon
It is classified into a vortex type, a wash-off type, a blow-out type, etc.

Of these, for example, in the case of a flush toilet bowl, as shown in FIG. 7, the toilet body (a)
A rim water passage (a) is provided on the inner circumference of the upper end of the rim, and a water spray hole (c) is provided on the entire lower surface of the rim water passage (a) so that cleaning water is discharged. Since the rim water passage (a) communicates with a water storage tank or the like via the water supply chamber (d) and the water supply port (e), for example, by operating the drain lever attached to the water storage tank, the rim water passage ( The washing water supplied to b) is discharged from the water spray hole (c) as shown by the solid arrow in the figure, and the bowl surface (f) of the toilet bowl is washed away. Then, by the water force of the wash water, the waste is discharged together with the accumulated water (K) from the discharge port (K) as shown by the broken line arrow in the figure.

On the other hand, in the case of a siphon-type or siphon-jet type flush toilet, for example, as in the siphon-jet flush toilet shown in FIG. However, by increasing the amount of accumulated water (Ki), the ball surface (F) is washed away by this accumulated water (Ki), and the siphon action is used to increase the drainage power of the waste, resulting in an increase in the cleaning power. ing.

As described above, the conventional flush toilets differ in the form of draining flush water and filth, but the flush water is drained from the water storage tank or the like to the rim water passage (a) as described above. It is almost common in that water is discharged from the water injection port (c).

[0006]

However, in any of the conventional flush toilet bowls, there remains a problem to be solved in terms of drainage and cleaning of waste. That is,
For example, in the case of the wash-out type toilet illustrated in FIG. 7, since the waste water is discharged only by the water force of the wash water, the wash water discharged from the water spray hole (c) urges the ball surface (f). It is desirable to flow well, and to run down like hitting the surface of the accumulated water (ki). Therefore, the ball surface
Is the ball surface (face) near the water surface where the wash water is
Designed to jump over and run off. However, in such a washing water flow-down method, the washing water jumps over the ball surface (k '), so that there is a drawback that dirt attached to the ball surface (k') cannot be sufficiently washed out. ..

Also in the case of the siphon type toilet illustrated in FIG. 8, in common with the above-mentioned flush type, since the bowl surface of the toilet bowl is usually dry, dirt is likely to adhere to the toilet bowl and However, the adhered dirt may not be removed. Therefore, in order to eliminate the discomfort caused by the remaining deposits, wash the toilet bowl with water before using the ball surface.
It required troublesome work such as wetting (mosquito ') and dropping paper.

Further, if dirt is attached, it must be cleaned with a toilet or the like and rinsed with cleaning water. However, such a cleaning operation is troublesome and uses a large amount of cleaning water, which is not economically preferable. On the other hand, in recent years, as a solution to such problems of conventional flush toilets, a toilet flush device equipped with means for forming a water film on the ball surface (f) before use (Japanese Patent Publication No. No. 51015) is also proposed.

However, in the case of this apparatus, both the cleaning water for forming the water film and the cleaning water for the normal waste water discharge have the same water supply system, for example, the water spray holes (shown in FIGS. 7 and 8). C), it is necessary to flow a large amount of high-pressure washing water in order to spread the washing water and form a water film, which is not preferable in terms of energy saving and economical efficiency. .. In addition, since the cleaning water is discharged from the same water spray hole (c) by different control means, there is a problem that the structure of the device including the piping and the like is large and complicated.

The present invention has been made in view of the above circumstances, and it is possible to eliminate the drawbacks of the conventional flush toilet bowl and form a water film on the ball surface with an appropriate amount of water.
It is an object of the present invention to provide a flush toilet bowl having a simple structure with excellent economical efficiency, which can effectively prevent adhesion of dirt.

[0011]

In order to solve the above-mentioned problems, the present invention forms a water film on the ball surface by ejecting washing water from the nozzle communicating with the water storage tank along the inner wall of the toilet bowl. A flush toilet comprising: a first flushing means; and a second flushing means for supplying water from a water storage tank and discharging dirt from the toilet bowl.

In the flush toilet of the present invention, a water guiding groove is preferably provided on the inner wall of the toilet bowl.

[0013]

In the flush toilet of the present invention, a water film is formed on the bowl surface of the toilet by the first cleaning means. For this reason, adhesion of dirt to the ball surface is effectively prevented. The first cleaning means communicates with the water storage tank in the same manner as the second cleaning means for discharging the waste from the toilet, and each of them is configured as a separate pipe water supply passage and cleaned by the discharge nozzle of an independent means. Spout water. Therefore, unlike the conventionally known toilet bowl, it is not necessary to use an excessive amount of flush water for the first flushing means. Moreover, the formation range of the water film can be controlled by adjusting the amount of water. The range of water film formation by the first cleaning means can be more easily controlled by the water guiding groove provided on the inner wall of the ball.
