Definitions

• the present invention relates to flush toilets that have a drain above the floor.
• An oral toilet of a mouth-to-mouth type has been known (for example, Japanese Utility Model Publication No. 61-106584).
• the flush water tank height is dimensioned so that it can be integrated with the toilet body itself. .
• wall drain type toilets are generally designed so that the center of the drainage outlet is 100-150 aa above the floor due to the construction and the function of the toilet.
• the height of the above-mentioned drainage outlet is secured by using the cubic toilet bowl of Eve as the wall drainage type, the drop from the water surface of the ball section to the core of the drainage outlet is reduced, and the above-mentioned poor water supply conditions are satisfied and the function is satisfied.
• the flush type toilets of the Wambies type are treated as the highest-grade toilets, so there are many requests for the installation of this Umbies type toilet in high-grade mansions, high-grade hotels and suite rooms.
• ceiling beams are often obstructed by drainage pipes, and in the case of high-rise buildings, etc., the height of the ceiling is reduced by removing the space for ceiling pipes. Since a space in the vertical direction is often secured, a conventional flush type toilet bowl that requires floor drainage and drainage pipes must be arranged under the floor often cannot meet the demands of the above market.
• the trap-drainage channel has a new structure in which a siphon is easily generated and a strong siphon force can be obtained. It is intended to enable wall drainage in a toilet type flush toilet.
• the technical measures taken by the present invention in order to solve the above problems are:
• the drain of the drainage channel is opened on the side surface of the toilet body, and the trap drainage channel is provided with a water reservoir downstream of the weir and between the weir and the water reservoir. Partially narrow the trap drainage channel, and hang a partition wall on the upper wall of the water reservoir, leaving a slight ventilation space between it and the water surface of the water reservoir. A gap is provided.
• the water bundle falling from the weir portion and the rise of the water level in the water pool portion divide the ventilation space into a wall-shaped partition.
• the air inside the tub is quickly pushed out to the drain port side by the eternal force, and the inside of the tub drainage channel has a negative pressure, so siphons are likely to occur.
• (A) is a toilet body
• (B) is a flush water tank formed integrally with the upper rear half thereof.
• the flush water tank (B) has a flush body as small as possible. according to the a) have been made form as impart a sense of unity with the toilet body 0
• the toilet body (A) has a rim water passage ( 9 ) provided along the upper part of the bowl (1), and a flush water tank ( 9 ) provided through a water supply chamber provided at the rear of the bowl (1).
• the washing water in the tank is mixed with water at the bottom, and a part of the water is supplied from the water hole formed on the lower surface of the rim water passage (9) along the hole (1) wall surface. The majority of the water is supplied in a swirling manner from the discharge port ⁇ W to the bottom of the ball section CO.
• the toilet body WI is provided with a trough drainage channel (2) for discharging the washing water supplied to the ball portion (1) together with dirt to the outside of the toilet in communication with the ball portion (1).
• the flush drain ( 2 ) has an inlet at the bottom of the ball section (1) and an outlet, i.e., the drain ( 3 ) is located at the back of the toilet body (A), and the washing water tank (B) )
• An opening is formed at a substantially intermediate position between the lower end and the lower end of the toilet body W, and a connection is made between these two 4 ( 3 ) to form a substantially inverted S-shape.
• the trap drainage channel (the ball opening (the bottom opening at the bottom of D) (the part that extends obliquely upwards (hereinafter referred to as & part) A portion that extends approximately vertically downward intermittently at the upper end of the part and reaches a position below the height of the inlet and drain (3) (referred to as the lower part), and continues to this part And a part extending obliquely upward toward the drain port (3) ( ⁇ below; referred to as a part).
• the weir W is formed by the bottom wall at the upper end of the part a.
• the diameter of the portion is gradually reduced downward so that the diameter of the drainage channel is partially narrowed, and a pool is formed from the lower end of the portion to the middle of the portion c.
• the trap drainage channel (2) is located at the upper wall of the pool ( 5 ), specifically at the boundary between the portion and the portion c.
• the partition wall (7) extending toward the bottom and the bottom of the pool ( 5 ).
• the partition wall is provided with a notch (3) having an appropriate width from the lower end to the middle part in the height direction.
• the ventilation space ( 6 ) causes siphoning, it is optimal to set the dimension of the 'to about 20.
• the toilets of the Rosilette type have been described.
• a siphon or a toilet bowl may be used. (Effect).
• the present invention has the following advantages since it has the above configuration.
• instantaneous water supply! Notably lower than tank-closed toilets and flush toilets, and as a wall-drain type, ensures that the height of the core of the drain is about 100 above the floor.
• the ball A mouth with a small drop from the reservoir surface to the drain outlet core It can be used as a wall-to-wall type toilet with a single outlet, yet it is possible to obtain a satisfactory drainage function as a wall drain type.
• the ceiling beams often hinder the underfloor piping, and the piping space above the ceiling is often omitted, and it has been difficult to install conventional toilets of the Rosilette Set type. It can be installed in high-rise buildings, luxury apartments, luxury hotels, etc. without any obstacles, and can respond to market demands.
• the notch does not affect the starting time of the siphon or the strength of the siphon at all at the start of the siphon since a water film is formed by the water flux from the weir.
