Abstract

PURPOSE:To reduce an amount of cold water at an initial stage discharged through a hand washing water discharge pipe. CONSTITUTION:A hot water tank 24 is connected to a branch valve 44 through a feed water receiving pipe 48 with a solenoid valve 51. A hand washer 52 is arranged to the upper part of a tank cover 40 and a hand washing water discharge pipe 54 is installed. A valve 56 for washing a hand is located in the middle of a hot water piping 28 and the valve 56 for washing a hand is connected to the hand washing water discharge pipe 54 through a feed water piping 58. The feed hot water piping 58 is extended around only at the interior of the tank cover 40. Since a hot water tank 24 is arranged on the upper surface of the rear part of a closet 10, a distance between the hot water tank 24 and the hand washer 52 is short. Thus, a feed hot water piping 58 through which the hot water tank 24 is connected to the hand washing water discharge pipe 54 is short and an amount of cold water at an initial stage discharged through the hand washing water discharge pipe 54 is eminently reduced.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention In a tightly coupled Western-style toilet having a low tank installed on the rear upper surface of a Western-style toilet, a hand-washing device may be provided above the low-tank. When attempting to supply hot water from the tank, as shown in FIG. 3 of JP-A-59-88548, the hot water supply pipe is exposed and the appearance becomes significantly poor.

Further, since the distance between the warm water tank and the hand-washing spout pipe is long, there is a problem that cold water is spouted for a considerably long time at the initial stage of discharge.

In particular, in a Western-style toilet with a hot-water washing device in which the warm-water tank is installed in the Western-style toilet, since the volume of the warm-water tank is relatively small, the user waits until the initial cold water is discharged. A large amount of warm water in the hot water tank flows out to the hand-washing side, the water temperature in the hot water tank drops considerably, and only low-temperature water can be jetted at the time of the next buttock cleaning using the toilet bowl.

[0006]

According to a first aspect of the present invention, there is provided a western-style toilet having a hand-washing device, wherein a low tank is installed on a rear upper surface of the western-style toilet and a hand-washing device is installed above the low-tank. In a Western-style toilet having a hand-washing device provided with a warm-water washing device for washing the buttocks with warm water and a washing nozzle, the hot-water tank is installed on the rear upper surface of the Western-style toilet, and the hot-water tank is used for the hand washing device. The hand-washing device is characterized by being connected to the hand-washing water discharge pipe by hot water supply pipe.

According to a second aspect of the present invention, there is provided a western-style toilet having a hand-washing device, wherein the hot water tank and the low tank are covered with a synthetic resin tank cover, and the hand-washing device is formed on an upper surface of the tank cover. The hot water supply pipe is provided only inside the tank cover.

[0008]

In the western-style toilet having the hand-washing device according to the first aspect, the hot water tank is provided on the rear upper surface of the western-style toilet, so that the distance between the warm-water tank and the hand-washing device is short. Therefore, the hot water supply pipe connecting the hot water tank and the hand-washing water discharge pipe is short, and the amount of initial cold water discharged from the hand-washing water discharge pipe is extremely small.

In the Western-style toilet having the hand-washing device according to the second aspect, since the hot water supply pipe is provided only inside the tank cover, the hot water supply pipe is completely invisible from the outside and is very attractive. In addition, the hot water supply pipe does not interfere with the cleaning of the toilet room. Furthermore, even if a thick heat insulating material or a heater is wound around the hot water supply pipe, they are not visible from the outside and do not affect the appearance at all. Therefore, sufficient heat retention can be achieved by using a thick heat insulating material or heater.
