Abstract

PROBLEM TO BE SOLVED: To obtain hot water at low cost, and use effectively electricity for a heated toilet seat being wasted purposelessly, by passing a hot water pipe in a hollow heat source room of the heated toilet seat, supplying water to the room by a supply pipe and discharging hot water from a faucet to a washbasin via a hot water supply pipe. SOLUTION: A hot water pipe 12 is passed into a hollow heat source room 11 of a heated toilet seat, to which water is supplied by a water supply pipe 7 and hot water is discharged to a washbasin 5 from a faucet 6 via a hot water supply pipe 8. Therefore, if water is passed to the heat source room 11 of the heated toilet seat 1, it is also always heated. Therefore, as a separate hot water washbasin is not needed, a space can be saved, installation is easy and hot water can be obtained cheaply. The use of heat for the heated toilet seat leads up to effective use of electricity and helps an eldery person or a person with hypertension who should be protected against the shock of cold water wash their hands with hot water, and water can be saved because no separate hot water heating device is needed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water heater using heat from a heated toilet seat.

[0002]

2. Description of the Related Art Conventionally, there has been a heater (refer to FIG. 1) in which a set of a toilet bowl, a hand-washing bowl, and a water storage tank, which is used for flushing toilet seat waste and hand-washing water, is provided. However, this hand washing water has a drawback that it remains cold, and there is a danger to the elderly and people with hypertension in the cold season. Here, there is no correlation between the three-point set and the heating toilet seat. Regardless of whether or not a heated toilet seat is used, the toilet seat must be constantly heated, and wastes electricity. The conventional type has a direct connection between B and C (FIG. 1) as shown by a dotted line.

[0003]

SUMMARY OF THE INVENTION In order to eliminate these drawbacks, the present invention has been studied to obtain warm water at a low cost and to effectively use the electric power of a waste heating seat. Was.

[0004]

A hot water pipe (12) is passed through a hollow heat source chamber (11) of a heating toilet seat (1). Water is supplied from a water supply pipe (7), and hot water is discharged from a faucet (6) to a hand washing machine (5) through a hot water supply pipe (8).

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Since the present invention is constructed as described above, if water is passed through the heat source chamber (see FIG. 2) of the always warm heating toilet seat, the water will always be heated. In other words, wasteful electricity consumption of the heating toilet seat is effectively used, and hot water for hand washing can be obtained without providing a separate water heater.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A toilet seat (9) constituting a heating toilet seat (see FIG. 2)
And the heat source chamber (11) sealed by the lid (13) is always warm by the electric heater (10). Here is a hot water pipe (12)
1 is not connected directly to B and C shown in FIG. 1 but is bypassed to obtain sufficient warm water for hand washing. In FIG. 1, the shape of the heating toilet seat is round, but it may be a front split type. Although five electric heaters (10) and four hot water pipes (12) are shown in FIG. 2, the number is not limited.

[0007]

According to the present invention, since the water heater is constructed as described above, the following effects can be obtained. 1. Since there is no need to provide a separate hot water handwasher, it can be installed at a low cost and hot water can be obtained at low cost. 2. Since the heat from the heated toilet seat, which is always warm, is used, electricity is effectively used. 3. Elderly people and people with hypertension, etc., who are dangerous to contact with cold water and have a danger of getting hot, can wash their hands warmly and save water because they are not separate water heaters.
