DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water toilet for a toilet.

[0002]

2. Description of the Related Art Conventionally, in order to perform hand washing in a toilet, water is drained from a hand washing faucet by operating an operation knob of a low tank behind the toilet, and the hand is washed by this, and the water is returned to the low tank as it is and stored. Was.

[0003]

In the conventional hand washing method, hands are washed with cold water in winter, which is very difficult. As a countermeasure, it is conceivable to install a water heater in the toilet room.However, ordinary household toilets usually have no place to install a water heater that blocks the room, and construction of hot water supply pipes or gas pipes is extremely difficult. However, there is a problem that the construction cost and the like are too high, and in practice, it was almost impossible.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention aims to provide a hot water hand-washing machine which exhibits satisfactory performance in a limited space, has good operability, and requires no construction. Is what you do.

[0005] Therefore, according to the present invention, a main body of a hot water hand washer is installed above a low tank, a faucet of the low tank is connected to a water inlet of the main body, and a hot water tank and a hot water mixing device are provided in the main body. High-temperature hot water heated in a hot-water tank is guided to a hot-water mixing device, and hot and cold water are mixed by the hot-water mixing device so that hot water of an appropriate temperature is supplied from a faucet.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a small amount of hot water for hand washing may be used, and as a means for securing this small amount of hot water, hot water is prepared and stored in a hot water tank and mixed with cold water at the time of use. Thus, the amount can be reduced, that is, the product can be downsized. By connecting the water inlet of this water heater and the low tank hand washing faucet, the water from the hand washing faucet is fed from the water inlet of the water heater by flushing the toilet flush water with the operation knob after stool.
The hot water stored in the hot water storage tank and the cold water inlet side of the hot water mixing constant temperature device are separated and flow into the hot water tank, and the hot water stored in the hot water tank is pushed out, discharged from the hot water tank outlet and flows into the hot water mixing / heating constant temperature device. It is mixed with cold water to form an appropriate temperature water of 35 to 40 ° C., and is discharged from a hand washing faucet provided on the outer shell of the main body and provided for hand washing.

[0007] The adoption of a mixture of cold and high-temperature water makes it possible to increase the execution capacity even if the hot water tank is small. For example, in the case of storing 70 ° C hot water, mixing with 10 ° C tap water to make handwashing water of 35 ° C, the ratio of hot water of 70 ° C to about 6 for 10 ° C water is 2.5 times the hot water tank capacity. The capacity can be obtained, and when using a 700 cc hot water tank, 1.5 L of hot water for hand washing can be taken out.

Further, the push-out pressure for taking out the hot water can be used by operating the knob of the toilet flushing water flow without using a member such as a pump, and can be used without any change as in the case of hand washing without a normal water heater.

The water after hand washing is dropped into a low tank hand washing water receiver and returned to the low tank as before.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG. 1 is a view in which a hot water hand washer is mounted above a low tank, FIG. 2 is a structural explanatory view of the hot water hand washer, and FIG. 3 is a cross-sectional view of a hot water mixing apparatus.

In FIG. 1, reference numeral 1 denotes a hot water tank having a capacity of about 700 cc formed of a heat-resistant resin. The hot water tank 1 has an electric heater 2 for heating water and a heating water temperature of 60 to
A temperature detector 3 such as a thermistor that controls the temperature to 70 ° C. is attached. Further, a cold water inlet A4 is formed near the bottom surface, and a tap hole 5 is formed on the upper surface portion. 5a is a hot water supply pipe connecting the tap 5 and the hot water inlet 10 of the hot water mixing device 6. 6
Is a hot and cold water mixing device that slides the cylinder 6a by a shape memory alloy spring 7 and a tension bias spring 8 to change the inflow opening area of hot water and water to produce constant-temperature hot water.
A hot water inlet 10 and a mixing outlet 11 are formed. Further, the shape memory alloy spring 7 and the tension bias spring 8
Are provided in the same direction with respect to the cylinder 6a.
Reference numeral 12 denotes a water supply member having a connection member 15 connected to the hand washing faucet 14 of the low tank 13, which is branched on the way and introduced into the cold water inlet A4 of the hot water tank 1 and the cold water inlet B9 of the hot and cold water mixing device 6. The part B17 is formed. 18
Is connected to the mixing outlet 11 of the hot and cold water mixing device 6,
It is formed by a metal bellows hose with a warm water hand washing faucet extending from the outer shell to the outside. Reference numeral 20 denotes a control unit that controls the electric heater 2 in response to a change in the resistance of the temperature detector 3. Reference numeral 21 denotes an operation knob provided for the flush water for flushing the toilet provided on the low tank 13, reference numeral 22 denotes a Western-style toilet, and reference numeral 23 denotes a power supply cord to the electric members of the hot water tank 1.

In the above configuration, when the water heater is set, and the operation knob 21 of the low tank 13 is operated to flush the toilet flush water, the connection member 15, the water supply member 1 and the hand washing faucet 14 are connected.
2 flows into the inlet A16 and the cold water inlet A
4 to make the hot water tank 1 full. One is the introduction section B1
7. The water flows into the hot and cold water mixing device 6 through the cold water inlet B9.
The cold water flowing into the hot and cold water mixing device 6 is mixed with the high-temperature water flowing from the hot water tank 1 to have an appropriate temperature, passes through the mixing tap 11, and flows out of the hot water hand-washing faucet 18.

In this state, the electric heater 2 is energized and the temperature in the hot water tank 1 is reduced by the temperature detector 3 and the control unit 20 to 6 times.
The heating time is maintained at 0 to 70 ° C. The time required for this heating is, for example, a hot water tank capacity of 700 cc and an electric heater 30.
At 0W, it takes about 10 minutes when the tap water temperature is 10 ° C.

Next, in actual use, when the operating knob 21 is operated after stool operation, the hot water in the hot water tank 1 is pushed out, flows into the hot / water mixing device 6, mixes with the cold water flowing from the introduction part B17, and a predetermined set hot water is discharged. The hot water is discharged from the faucet 18 for hand washing.

The hot water in the hot water tank is used up once by the above operation, and the water in the hot water tank is heated until the next user uses it. The setting of the interval time makes it possible to set the interval time.

[0016]

The combination of the high-temperature hot water storage and the hot / cold water mixing system makes it possible to realize a sufficient amount of hot water for one-time hand washing with a very small water heater and to attach it to the low tank portion with no space. Moreover, no plumbing work is required, and the price is very low.

Further, since the spring made of shape memory alloy and the tension bias spring are provided in the same direction with respect to the cylinder, the hot and cold water mixing apparatus can be made compact, and the hand washing machine itself can be reduced in size and inexpensive. .

Further, a pumping member such as a pump is not required, and can be used without any difference from the conventional hand washing operation, so that the usability is extremely improved.
