Abstract

PURPOSE:To improve cleanliness, energy saving property and handling convenience of the device by a method wherein the device is constituted so that hot-water is discharged when a part of a hot-water discharging cock is touched by a finger and the discharge of hot-water is stopped when the tip end of the cock is touched by a finger again by utilizing a touch-switch, put ON or OFF with contact of a human body as a control device. CONSTITUTION:A conductive member 13 is arranged at the tip end of the cock tube 3 through an insulating member 12 and the conductive member 13 is connected to the touch-switch in the control device 6 through a lead wire 14. The control device 6 accommodates the touch-switch utlizing that it is connected to a capacitor electrically when the human body touches it, therefore, the switch of the control device 6 is put ON when the cock 3 is touched by a finger, a solenoid valve 5 is opened to flow city water, a pressure difference is generated, a main burner 19 is ignited and hot-water is discharged when an electric source 20 is set previously, a pilot burner 16 is being ignited and the user wants to discharge the hot-water. When the user wants to stop the discharge of the hotwater, the switch of the control device 6 is put OFF by touching the conductive member 13 at the tip end of the cock tube 3 by finger, the solenoid valve 5 is closed to stop the supply of city water and a diaphragm valve 18 is operated to extringuish the main burner 19.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides heavy control over the water supply source in water heating devices such as gas instantaneous water heaters, electric water heaters, oil instantaneous water heaters, etc. It's about structure.

Opening of conventional examples and their problems Conventionally, in this type of hot water N11 device, a lever set or dial type manual valve is provided on the main body as a device for opening and closing hot water, and hot water is dispensed by manually operating it. I started or stopped it.

Therefore, when a person operates a valve by hand, if his or her hands are dirty or have detergent on them, the lever or dial of the valve becomes dirty, and furthermore, the lever and the valve body near the valve become dirty.

Alternatively, since the faucet and the faucet are usually separated, there is a time lag between opening and closing the hot water and when the hot water is used, resulting in wasted water.

For example, in the conventional example shown in FIG.
The opening/closing lever 2 provided on the J side and the faucet 3 made up 1.14 pieces. Therefore, each time the opening/closing lever 2 was operated, the above-mentioned problem occurred.

Purpose of the Invention The present invention solves the above-mentioned conventional problems, and uses a touch switch that turns on and off when a human body touches the control device, so that when a part of the faucet is touched with the hand, hot water comes out, and the tip of the faucet is turned on and off. When the water heater is touched with the hand, the hot water stops, and the purpose is to improve cleanliness, energy saving, and usability.Structure of the InventionIn order to achieve the above object, the water heater of the present invention is provided with a main body. A water supply opening/closing device, a heating device for obtaining hot water, a faucet for introducing hot water, and a control device for controlling the water supply opening/closing device, the faucet being made of metal, electrically insulated from the main body, and A touch switch is provided at the tip of the faucet with a conductor insulated from the faucet, electrically conducting the control device, the faucet, and the conductor at the tip of the faucet 1, respectively. It is connected to a faucet and the tip of the faucet, and when the tip of the faucet is touched, the water supply on-off valve opens, and when the faucet is touched, the water supply on-off valve is closed, and hot water is automatically opened and closed just by touching it with the hand. Figure 2~
FIG. 4 shows a water boiler according to an embodiment of the present invention, in which a solenoid valve 5 for electrically opening and closing tap water is provided inside the main body 1.
A control device 6 for opening and closing the solenoid valve 5 is provided. A faucet pipe 3 is provided at the outlet of the main body 1. The faucet pipe 3 is configured to be electrically insulated from the main body 1, and FIG. and sea/l'li' 8 through snake 1
''The pipe 3 is connected by a fixed naso 1-10, and the faucet pipe 3 freely slides in the circumferential direction. In addition, the faucet pipe 3 has a conducting wire 11
is connected to a touch switch in the control device 6. On the other hand, the fourth
The figure shows a detailed view of the tip of the faucet pipe 3. A conductive material 13 is provided at the tip of the faucet pipe 3 via an insulating layer 12, and the conductive material 13 is connected to a touch switch in the control device 6 through a conductive wire 14. tied together.

The operation of the above configuration will be explained below.

In the water heating apparatus configured in this way, the pylon 1-16 is ignited by the manual valve 15 linked to the ignition device. When the solenoid valve 5 is opened, tap water flows from the water supply pipe 4 to the heat exchanger 17.
It flows out from the faucet pipe 3 via. Before and after the heat exchanger 17, a diaphragm 18 is activated by utilizing the difference in pressure loss in the pipes of the heat exchanger, and the main burner 19 is ignited, thereby heating the tap water and turning it into hot water.

The control device 6 has a built-in circuit that utilizes the fact that it is electrically connected to a capacitor when touched by a human, and has two circuits, one that turns on when touched, and the other that turns off. establish. A solenoid valve 5 is provided as a load of the circuit. Therefore, the faucet pipe 3 is connected to a circuit that turns on when touched with a conducting wire 11, and the other end is connected to a circuit that turns off when touched with a conducting wire 14 from the conductive material 13 at the tip of the faucet pipe 3. When you want to dispense hot water, turn on the power supply 20 seven times in advance and ignite the pilot 16. When you touch the faucet pipe 3 with your hand, the switch of the control device @ 6 is turned on, the electromagnetic = JP 5 is opened, and the tap water starts flowing. , a pressure difference is generated, the main burner 19 is ignited, and hot water comes out. Oh? : ,+L
: When you touch the conductor 44'13 at the tip of the snake Ll pipe 3, the switch of the control device 6 turns off and the electromagnetic jP5
is closed to stop the supply of tap water, and the tie flam valve 18 is activated to extinguish the main burner 19. Hot water comes out when you touch the pipe 3, and stops when you touch the conductive material 13. According to this embodiment, you can freely supply hot water just by touching it with your hand. It is highly convenient.

In addition to the above examples, 'I'If9C kettle silence, stone/lI
It can also be applied to faucets such as water heaters.

As described in detail, according to the water heater of the present invention, hot water can be turned on and off just by touching it with the hand, without opening or closing a valve. It is ideal for quiet areas, and since hot water can be dispensed only when needed, it does not use unnecessary printing presses, contributing to energy savings. Also, since there is no need to touch the main unit with dirty hands, the main unit can be kept clean.
