Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a simple flush toilet in which a small amount of water is pressurized and injected into a bowl to wash the bowl.

[Prior Art] Conventionally, a simple flush toilet in which a small amount of water is injected into a bowl has been known. In this simple flush toilet, as shown in FIG. 6, a ceramic bowl 2 is placed inside a toilet body 1 made of synthetic resin.
And the toilet body 1 is sealed with a watertight material 37, thereby forming a water tank portion 3 'in the space between the outer surface of the bowl 2 and the inner surface of the toilet body 1. The water tank 3 ′ is formed so as to surround the outer periphery of the bowl 2.

[Problems to be Solved by the Invention] However, in the above-described conventional example, the lower outer periphery of the ceramic bowl 2 and the toilet body 1 made of synthetic resin are made of a watertight material.
Sealing had to be performed according to 37, the assembly work was troublesome, and there was a risk of water leakage if the seal was broken. Furthermore, since the space between the inner surface of the toilet body 1 and the outer surface of the bowl 2 is defined as the water tank 3 ', the capacity for storing water is large. However, since a simple flush toilet uses only a small amount of water because a small amount of water is pressurized and jetted, there is a problem that a large amount of water is used and the water is rotten.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and aims at eliminating the need for a sealing material, simplifying the assembling work, and allowing an appropriate amount of water to be stored. It is an object of the present invention to provide a compact flush toilet.

[Means for Solving the Problems] The simple flush toilet of the present invention is a simple flush toilet in which a ceramic bowl is provided inside a synthetic resin toilet body.
A partition wall that is integral with the toilet body and is set back downwardly is provided in the rear portion of the toilet body to form a water tank portion on the rear side of the partition wall in the toilet body. It is characterized in that a diaphragm pump for pressurizing and injecting water in a water tank portion into a bowl is accommodated in a space between the partition wall.

[Operation] According to the present invention, a water tank portion having an appropriate capacity can be formed without requiring a watertight material. Also, in storing the diaphragm pump in the lower part of the toilet body and in the space between the rear of the bowl and the partition wall, the partition wall is assumed to retreat backward toward the lower side, and since the bowl is smaller toward the lower part, Even if the upper part of the water tank is close to the upper part of the bowl, a space for accommodating the diaphragm pump can be ensured in the lower part of the toilet body, and the diaphragm pump can be accommodated here.
