Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flush toilet device provided with a toilet and a low tank installed in a toilet room.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 3 and 4, a flush toilet device provided with a toilet 1 and a low tank 3 installed in a toilet room is generally known.

[0003] The flush toilet apparatus shown in FIG. 3 has a low tank 3 installed behind the toilet 1 and a hand-washing bowl 4 provided above the low tank 3. In this case, a water supply pipe 11 is connected between the low tank 3 and the toilet 1, and a water supply curan 12 is attached to the hand washing bowl 4. Then, the water discharged from the water supply cull 12 flows into the low tank 3 from the hand washing bowl 4 and is stored in the low tank 3.
The toilet 1 is supplied from the low tank 3 to the toilet 1 through the water supply pipe 11 as needed, for example, after use of the toilet 1, and the toilet 1 is washed.

In the flush toilet apparatus shown in FIG. 4, a low tank 3 is installed on the rear of the toilet 1 and a hand-washing bowl 4 is separately provided on the wall 2 of the toilet room on the side of the toilet 1. In this case, the hand-washing bowl 4 is located on the front side of the toilet 1, and the hand-washing bowl 4 is provided with a water supply cull 12. Can be washed. Further, a water supply pipe different from the pipe for supplying water to the water supply cull 12 is installed in the low tank 3, and water supplied from the water supply pipe is stored in the low tank 3. As appropriate,
The toilet bowl 1 is supplied from the low tank 3 to the toilet bowl 1 to be washed.

[0005]

However, the above-mentioned prior art has the following problems. That is, in the flush toilet apparatus shown in FIG. 3, since the low tank 3 is installed in the space behind the toilet 1, especially when the depth dimension X of the toilet room is small, the space dimension Y in front of the toilet 1 is also small. There was a problem that the space in front of the toilet 1 was narrowed, making it difficult to use. Moreover, in this case, the hand-washing bowl 4 provided on the upper part of the low tank 3 is located at the far end in the toilet room, and there is a problem that the usability of the hand-washing bowl 4 is deteriorated.

In the flush toilet apparatus shown in FIG.
Since the hand-washing bowl 4 is located in front of the toilet 1, the hand-washing bowl 4 is easy to use.
The water supply pipe to the water supply cull 12 and the drain pipe from the hand wash bowl 4 attached to the hand wash bowl 4 must be separately constructed from the low tank 3 and the water supply / drain pipe of the toilet 1, and the plumbing of the toilet room Is complicated and difficult. In addition, in this case, water is used separately for washing the toilet bowl 1 for hand washing in the hand washing bowl 4, so that there is a problem that water cannot be saved. Also, a low tank 3 is installed on the rear of the toilet 1,
The space Y in front of the toilet 1 is considered to be large. In this case, however, the toilet 1 itself is also increased by the amount of the low tank 3 installed. The problem of not being able to secure it still remained.

SUMMARY OF THE INVENTION The present invention has been made in order to solve all the problems in the above-mentioned conventional technology, and its object is to effectively utilize the space in the toilet room.

The water used for hand washing in the hand washing bowl flows into the water storage section in the low tank from the drain port and is stored therein, and is used again for washing the toilet, thereby saving water. In addition, the drainage from the hand-washing bowl is performed through the low tank, so that the drainage pipe for the hand-washing bowl is not required, and the piping work is simplified.

A flush toilet apparatus according to claim 3 of the present invention is
The flush toilet device according to claim 1 or 2, wherein a hand-washing bowl is formed by bulging from a side wall surface of the low tank at a front side of the toilet.

Therefore, in this case, particularly, since the hand-washing bowl protrudes from the side wall of the low tank at the front side of the toilet, the front part of the toilet is generally narrow, and the front side of the toilet is generally narrow. The space is effectively used, and the opening area of the hand-washing bowl is increased, thereby improving the usability.

A flush toilet apparatus according to a fourth aspect of the present invention comprises:
The flush toilet device according to any one of claims 1 to 3, wherein a storage portion opened toward the toilet side is provided vertically below the low tank.

Therefore, in this case, particularly, the storage portion opened toward the toilet is vertically provided below the low tank disposed on the side of the toilet, so that toilet paper such as toilet paper and detergent is provided in the storage portion. Equipment can be conveniently stored so that it can be easily taken in and out, and the storage section is located under the low tank, which is a dead space, so that it is not obstructed.
