Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a water supply pipe connected to a water supply passage, an electromagnetic on-off valve for opening and closing the water supply passage, and a manually operated switch for instructing the operation of the on-off valve. The present invention relates to a water supply device in which a water supply passage forming member is housed in a casing of a water outlet provided at the tip of the water supply pipe.

[0002]

2. Description of the Related Art The water supply device as described above is used as a water supply tap or a hot water supply tap. By the way, in order to switch between the water supply state and the water supply stop state at the user's hand, it is desirable to provide the switch on the water outlet. By the way, it is conceivable to use a completely waterproof switch as the switch when the switch is provided on the water outlet.

[0003]

In the above-mentioned prior art, the switch is expensive, and as a result, the cost of the water supply device may be high. An object of the present invention is to eliminate the above-mentioned conventional drawbacks, eliminate the need for using an expensive switch, and reduce the cost of the water supply device.

[0004]

In order to achieve this object, a first characteristic configuration of a water supply device according to the present invention is a water seal in which the switch is formed between the casing and the water supply passage forming member. It is provided in the space.

The second characteristic configuration specifies a preferable specific configuration for implementing the first characteristic configuration,
The heat exchanger for heating the water flowing through the water supply passage and the heating means for heating the heat exchanger are provided.

[0006]

The operation of the first characteristic configuration is as follows. A water-sealed space is originally formed between the casing and the water supply passage forming member. Therefore, by providing the switch in the water-sealed space, it is not necessary to use an expensive waterproof type switch.

According to the second characteristic configuration, the above-described operation can be obtained in the hot water tap in which the user can switch between the hot water supply state and the hot water supply stop state.

[0008]

EFFECTS OF THE INVENTION In the water tap according to the first characteristic configuration and in the hot water tap according to the second characteristic configuration, it is not necessary to use an expensive switch with a simple structure utilizing the original configuration, thereby reducing the cost of the water supply device. can do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a water heater will be described below with reference to the drawings. As shown in FIGS. 5 and 6, a heat exchanger 1 for heating water and a burner 2 as a heating means for heating the heat exchanger 1 are provided in the main body case A. Then, the flexible pipe 3 as a water supply pipe having the water outlet 4 at its tip is connected to the hot water supply pipe connection port 13 to form a water heater.

Further, in the water supply passage W1 which connects the water supply inlet 12 and the hot water supply pipe connection inlet 13 via the heat exchanger 1, an electromagnetic on-off valve 5 for opening and closing the water supply passage W1, a water governor 6, and Flow dividing valve 7 for adjusting the amount of water supplied to the heat exchanger 1 and the amount of bypass water
Is installed. In the fuel supply path G1 to the burner 2,
An electromagnetic shutoff valve 8, a water pressure responsive valve 9 that interlocks with the water governor 6, a gas governor 10, and a control valve 11 that adjusts the fuel supply amount are interposed. In the figure, S1 is a push switch, 14 is a water flow switch, 15 is a hot water temperature adjusting dial for adjusting the hot water temperature, 16 is an ignition plug, 17 is a thermocouple,
18 is a back thermocouple for incomplete combustion prevention, 20 is a lamp,
21 is a battery.

The structure of the water outlet 4 will be described. As shown in FIG. 1, the casing B of the water outlet 4 is an upper casing B1 attached to the tip of the flexible pipe 3.
And a lower casing B2 screwed to the upper casing B1.

The water passage in the flexible pipe 3 and the water passage in the lower casing B2 are communicated with each other via a cylindrical communication pipe 40. A water sealing member 41 is fitted on the upper end of the lower casing B2. That is, the upper casing B1
The space K formed between the communication pipe 40 and the communication pipe 40 is water-sealed. The communication pipe 40 and the water sealing member 41 are integrally formed. In FIG. 1, 42 and 43 are O-rings for water sealing. That is, the communication pipe 40 and the water sealing member 41 correspond to the water supply channel forming member C.

As shown in FIGS. 2 and 3, a micro switch S for instructing the operation of the opening / closing valve 5 in the water-sealed space K.
3 is provided. An operation member 44 for manual operation of the micro switch S3 is formed along the outer surface of the upper casing B1 and so as to surround the communication pipe 40. The operating member 44 and the micro switch S3
And a contact member 45 that contacts the movable piece 30 are rigidly connected. Further, the contact member 45 is the micro switch S3.
To the mounting member 46 for the upper casing B1 of FIG. A pair of leaf springs 47
Is a contact member 45 when the operating member 44 is pushed.
Is guided so as to move only in the perspective direction with respect to the micro switch S3, and is urged to return to the side separated from the micro switch S3. Here, as also shown in FIG. 4, the operating member 44, the contact member 45,
The mounting member 46 and the leaf spring 47 are integrally formed.
Then, the recess a is engaged with the first receiving portion 60, and the upper surface of the attachment member 46 is attached to the upper casing B1 in contact with the second receiving portion 61. In the figure, 48 is a tongue for fixing the microswitch S3, and 49 is a cable retainer.

The lower casing B2 is provided with a seesaw button 50 for selecting whether the state of hot water is shower or straight. In FIG. 1, 51 is a valve seat having a shower valve opening 52 and a straight valve opening 53, and 54 is a valve element that selectively closes one of the valve openings 52, 53.

[Other Embodiment] In the above embodiment, the present invention is applied to a hot water tap, but it can also be applied to a water tap. In the above-described embodiment, the water-sealed space K is formed on the rear surface side of the water outlet device 4, but it may be formed on the front surface side of the water outlet device 4 as shown in FIG. 7.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
