Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art A water supply device as described above is used as a water supply tap or a hot water supply tap which can be switched between a water supply state and a water supply stop state by a user. By the way, when the micro switch is attached to the water outlet, it is generally considered that an operating member for manually operating the micro switch and an attaching member for the casing of the micro switch are separately molded.

[0003]

When the operating member, the mounting member and the like are separately molded as described above, the number of parts is increased and, as a result, the assembly cost is increased. An object of the present invention is to eliminate the above-mentioned conventional defects, reduce the number of parts, and reduce the assembly cost.

[0004]

In order to achieve this object, a first characteristic configuration of a water supply device according to the present invention comprises an operating member for manual operation, which is formed along an outer surface of the casing, and the micro. The contact member that contacts the movable piece of the switch and the mounting member that attaches the microswitch to the casing are integrally formed.

A second characteristic structure is that a heat exchanger for heating the water flowing through the water supply passage and a heating means for heating the heat exchanger are provided.

[0006]

In the first characteristic configuration, since the operating member, the mounting member and the like are integrally molded, the number of parts can be reduced as compared with the case where they are molded separately.

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]

Since the number of parts can be reduced in the water tap according to the first characteristic configuration and the hot water tap according to the second characteristic configuration, the assembling cost can be reduced.

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.

As shown in FIGS. 2 and 3, the space K
A micro switch S3 for instructing the operation of the on-off valve 5 is provided therein. 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 contact member 45 that contacts the movable piece 30 of the microswitch S3 are rigidly connected. Further, the contact member 45 is connected to a mounting member 46 of the microswitch S3 for the upper casing B1 via a pair of leaf springs 47. The pair of leaf springs 47
When the operating member 44 is pushed, the contact member 45 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 operation 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 body that selectively closes one of the valve openings 52 and 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.

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.
