Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a technique for draining water from a bathtub placed on a floor pan.

[Background technology]

Conventionally, a bathtub placed on a floor pan is known. When draining the bathtub in a bathtub placed on the floor pan, the drain from the bathtub is usually allowed to drip onto the floor pan from the drain port of the bathtub. Water was drained to the outside through drainage holes provided in the floor pan due to the slope of the floor pan. However, in this conventional example, dirt, soap scum, hair, etc. flow from the bathtub onto the floor pan under the bathtub and are spread on the floor pan. The water was left unaltered on the floor pan under the bathtub, causing a foul odor. Therefore, the inventor of the present invention thought of arranging a drain pipe between the bathtub and the floor pan, and using this drain pipe to drain water from the drain port of the bathtub to the drain hole of the floor pan. In this case, when connecting the elbow 30 constituting one end of the drain pipe 3 to the drain port 5 of the bathtub 2 as shown in FIG.
must have the same diameter as the drain port 5, and for this reason, H in FIG. A new problem arises in that it is not possible to deal with the case (when the water is short), and for this reason, the diameter of the elbow 30 has to be made smaller to shorten the dimension of H, and in this case, there is a problem that it takes time to drain water.

[Purpose of invention]

The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to guide wastewater from the drain of the bathtub to the drain hole of the floor pan, so that no dirt or soap can be deposited on the floor pan. To provide a drainage structure for a bathtub that does not allow debris and hair to flow and accumulate and allows smooth drainage even when the legs of the bathtub are short (when the distance from the top surface of the floor pan to the bottom surface of the bathtub is short).

A trap portion (not shown) is provided in the drain hole portion 7. When cleaning the drain hole 7, the tightening by the wire band 26 is released and the lower pipe 21 is removed from the curved pipe 20, thereby opening the drain hole 7 for cleaning. By the way, when the curved pipe 20 avoids the legs 24, the curved pipe 20 is placed on the mounting base 25 protruding from the upper surface of the bathtub mounting part 8 of the floor pan 1, and this part
Even if the lower surface of the above-water side connection part 19 is raised above the upper surface of the floor pan 1 by the support part 6, the above-water side connection part 19
The water level can be made higher than the level of the curved pipe 20 and the lower water side pipe 21, and the water from the drain port 5 of the bathtub 2 can be drained smoothly into the drain hole part 7 of the floor pan 1, and the upper water side connection part 19 can be drained smoothly. This prevents wastewater from accumulating and causing bad odors. Reference numeral 29 in FIG. 2 is a weir provided in the floor pan 1, which separates the bathtub mounting part 8 and the washing area 9, on which the apron is placed.

[Effect of the idea]

In the case of this invention, as described above, the bathtub is placed on the floor pan, a drain pipe is placed between the bathtub and the floor pan, and the inlet at one end of the placement pipe and the drain port on the bottom of the bathtub are connected. Since the other end of the drain pipe is connected to the drain hole provided in the floor pan, the water from the bathtub can be drained through the drain pipe to the drain hole in the floor pan.
This eliminates the possibility of dirt, soap scum, hair, etc. flowing and accumulating on the floor pan with drainage and causing a bad odor, and it also has an inlet on the top that communicates with the bathtub drain. The internal cross-sectional area of the above-water connection is set larger than the cross-sectional area of the drain, so the distance from the inlet to the bottom of the above-water connection is shortened and the distance from the floor pan to the bottom of the bathtub is reduced. Even if the connection part on the water side, which has a large internal area, becomes a puddle, water from the drain outlet can be drained smoothly through the connection part on the water side, which has a large internal area. In addition, a guide pad made of rubber material is attached to the lower outer periphery of the drain fitting attached to the above-mentioned drain port of the bathtub, and a pleat part that extends all the way around the outer periphery of the guide pad is installed. A plurality of fitting recesses are provided on the upper and lower sides of the inlet, and the fitting recesses recessed on the upper surface of the inlet are fitted into the guide gasket through the pleats to communicate the drain outlet and the inlet. By inserting an elastic guide gasket between the fitting recess of the inflow section, the connection can be made securely so that the connection part does not come off. The parts can be tightly sealed to ensure a secure connection to prevent water from leaking.
