Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved toilet device.

[0002]

2. Description of the Related Art As a conventional toilet device, as shown in FIGS. 5 and 6, a bowl 2 for storing sealed water communicates with a bowl 2 near the bottom surface of the bowl 2, and a trap 3 is connected to a drain pipe at an end thereof. There is a toilet bowl body 1 having a and a wash water supply device (not shown) located behind the opening 4 of the bowl 2 and supplying wash water to the bowl 2. In this toilet device, a space 20 between the opening 4 of the bowl 2 and the flush water supply device is a hollow space 20 of the toilet body 1.
Through holes 21 and 22 are opened on the rear side, that is, on the side of the washing water supply device (not shown) and on the front side, that is, on the side of the bowl 2, and the rear side through hole 21, the hollow space 20 and the front side through hole 22 are formed. The cleaning nozzle 15 is arranged so as to be inserted therethrough. The thickness of the through holes 21 and 22 is substantially the same as the wall thickness of the toilet body 1.

[0003]

In the prior art, the cleaning nozzle 15 is inserted up to the vicinity of the bowl 2 in order to spout the cleaning water so as not to scatter, and the cleaning nozzle 15 and the cleaning water supply from the rear side of the space 20. There were many parts, such as the need for piping to connect to the equipment. And the cleaning nozzle 1
Even when 5 is inserted up to the vicinity of the bowl 2, the hollow space 20 of the toilet bowl body 1 is wide, and the positioning of the nozzle on the bowl side is performed only by the inner edge of the through hole 22 having a thickness dimension substantially the same as the wall thickness of the toilet bowl body. Therefore, the positioning of the cleaning nozzle 15 is insufficient, and there is a possibility that cleaning water may jump out. Further, without using the cleaning nozzle 15, the space portion 2 is directly supplied from the cleaning supply device (not shown) through the through hole 21.
When the wash water is supplied to 0 and the water is discharged from the through hole 22 to the bowl 2, the thickness of the through hole 22 is substantially the same as the wall thickness of the main body of the toilet bowl. The direction was not stable.

Therefore, an object of the present invention is to provide a cleaning nozzle that discharges cleaning water substantially horizontally along the inner surface of the bowl directly below the rim of the toilet body along the inner surface of the bowl, and located behind the opening of the bowl. Another object of the present invention is to realize an inexpensive toilet bowl device having a cleaning water supply device for supplying cleaning water to the cleaning nozzle, with a reduced number of parts, and to prevent splashing and splashing of the cleaning water. Further, without using the cleaning nozzle, a spout for discharging flushing water is provided integrally with the main body of the toilet directly below the rim of the main body of the bowl and substantially horizontally along the inner surface of the bowl along the inner surface of the bowl. (EN) It is intended to provide a toilet bowl device in which the direction of water discharge from the water is stable and the washing water is prevented from splashing or splashing.

[0005]

MEANS FOR SOLVING THE PROBLEMS AND OPERATIONS AND EFFECTS THEREOF The present invention relates to a toilet bowl having a bowl for storing sealed water and a trap which communicates near the bottom of the bowl and whose end is connected to a drain pipe. A flush toilet device comprising a main body and a flush water supply device which is located behind an opening of the bowl and supplies flush water to the bowl, wherein the flush toilet body communicates with the flush water supply device. A spout is provided directly below the rim of the toilet body along the inner surface of the bowl for discharging flush water, and the length of the spout is longer than the wall thickness of the body. And has substantially the same cross-sectional area. Since the dimension in the lengthwise direction of the water discharge port is a predetermined length larger than the wall thickness dimension of the toilet body and has substantially the same cross-sectional area, the cleaning water supplied from the cleaning water supply device is Sufficiently rectified water is discharged from the tip of the spout, and splashing or splashing of wash water is prevented. In addition, a stable flow of cleaning water can be supplied to the bowl without using a separate cleaning nozzle, and an inexpensive toilet device can be realized.

In a preferred embodiment of the present invention,
The water outlet is formed by joining a body forming body including a bowl for forming the body of the toilet bowl and a rim forming body above the ball. By doing so, the spout having a desired length can be easily formed.

Further, according to the present invention, there is provided a bowl main body having a bowl for storing sealed water and a trap which communicates near the bottom surface of the bowl and has a terminal end connected to a drainage pipe, and a rim of the bowl main body. Immediately below, a cleaning nozzle that discharges cleaning water substantially horizontally along the inner surface of the bowl forward from the side of the bowl, and a cleaning water supply device that is located rearward of the opening of the bowl and supplies the cleaning water to the cleaning nozzle. A urinal device provided with the urinal, wherein a through-passage for internally fitting and supporting the water discharge end of the cleaning nozzle is integrally formed with the urinal body, and the through-pass has a length dimension of the urinal body. Is larger than the wall thickness dimension and has substantially the same cross-sectional area. Since the through-passage that fits and supports the spout end of the cleaning nozzle is larger than the wall thickness of the toilet body and has substantially the same cross-sectional area, cleaning is performed simply by inserting the cleaning nozzle into the through-passage. The position of the end of the spout of the water nozzle is easily determined, and the flush direction of the flush water from the spout is stable and the flush water does not jump out of the bowl.

[0008] In a preferred aspect of the present invention, a chamfered portion (C surface) is provided at the insertion port of the cleaning nozzle of the through passage. By providing the chamfered portion (C surface) at the insertion port, the chamfered portion serves as a guide when the cleaning nozzle is inserted into the through passage, and the cleaning nozzle is smoothly inserted.

In a preferred embodiment of the present invention,
The through passage is formed by joining a body forming body including a bowl portion for forming the body of the toilet bowl and a rim forming body above the ball. By doing so, a through passage having a desired length can be easily formed.
