Description

[Detailed Description of the Invention] The present invention relates to a water heater with a hermetic stopper that seals the opening of a container.

With conventional sealed plugs that have a hot water supply valve, the hot water supply lever must be slid in one direction to open the hot water supply valve, and in the opposite direction to close it, which is not only cumbersome to operate, but also prevents the hot water supply valve from closing if the hot water supply valve is forgotten. If it falls over, hot water will flow out and it is dangerous.

Therefore, it is possible to provide a spring in the hot water supply valve and use this spring to always bias the hot water supply valve in the direction of closing, but in this case, when opening the valve to supply hot water, the hot water supply valve must be continuously pressed. It's troublesome.

It is also conceivable that a locking mechanism is provided to hold the hot water supply valve in the open position, but in this case, it is necessary to provide a locking mechanism and a release mechanism to release the lock.
There was a risk that the structure would be complicated and the release operation would be troublesome.

The present invention was devised in view of these problems, and aims to provide a water heater with a tightly closed plug that allows locking and unlocking of a hot water supply valve with a simple structure, and allows easy unlocking operation. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples.

In FIG. 1, 1 is the main body of an electric kettle, which is an example of a container, and inside this main body 1 there is a heater (not shown) at the bottom.
An inner container 2 having a molten metal is housed and fixed therein, and a shoulder body 3 integrally provided with a pouring pipe 4 is mounted and fixed on the upper end of the main body 1.

The upper end opening of the inner container 2 is hermetically fixed to the shoulder body 3 via a packing 5.

Note that 6 is a handle. Reference numeral 7 denotes a seal plug detachably attached to the center of the shoulder body 3, and this seal plug 7 is connected to the plug body 8.
It is composed of a stopper lid 12 and a stopper bottom plate 15.

The tap body 8 has a hot water supply port 9 that communicates with the hot water pouring pipe 4, and a hot water supply valve 10 for opening and closing the hot water supply port 9 is attached so that it can move forward and backward and is biased by a spring 11 in a direction to close the hot water supply port 9. ing.

The front end of the stopper body 8 is provided with a protrusion 8a that engages with the inner surface of the pouring pipe 4 of the shoulder body 3, while the rear end of the stopper lid 12 is provided with a hook lever 13 that is supported by a spring 14 as shown in FIG. The hook lever 13 is biased toward the right when attached, and the protrusion 13a of the hook lever 13 engages with the hole 3a of the shoulder body 3.

Thereby, the seal plug 7 is removably attached to the shoulder body 3, and in the attached state, the outer circumferential portion of the stopper plate 15 is pressed against the gasket 5 to seal the inside of the inner container 2.

The above-mentioned tap lid 12 has a hot water supply lever 16 for operating the hot water supply valve 10.
The hot water supply lever 16 includes an operating body 17 that constitutes an operating section and a pressing body 21 that constitutes a pressing section.

As shown in FIGS. 3 and 4, the operating body 17 has a fitting claw 18, a hanging wall 19, an engaging claw 20, and a chevron-shaped rib 30 projecting from the lower surface.

Further, as shown in FIGS. 5 and 6, the pressing body 21 has a square hole 22 in its upper part that is fitted with the fitting pawl 18 and integrated therewith, and has a shaft part 23 projecting from both sides. It has a protruding piece 24 on the lower part that presses the end of the hot water supply valve 10.

On the other hand, a hanging wall 19 of the operating body 17 is provided on the upper surface of the stopper lid 12.
The lower surface of the chevron-shaped rib 30 has a slidable recess 25. The recess 25 has an opening hole 26 in its center, an engaging protrusion 27 on the front side, and a step 28 on the rear side. Each is provided.

The operating body 17 and the pressing body 21 are integrated by fitting and fixing the fitting claw 18 into the square hole 22 with the opening hole 26 in between.

At this time, the upper surface of the shaft portion 23 of the pressing body 21 comes into contact with the lower surface of the stopper lid 12.

This prevents the hot water supply lever 16 from being pulled out.

The operation of the water heater having the above configuration will be explained.

First, when the hot water supply lever 16 is slid to the left in FIG.
Hot water supply valve 10 opens hot water supply port 9.

Then, the engagement claw 20 of the hot water supply lever 16 rides on the engagement protrusion 27 of the tap lid 12, and the engagement claw 20 and the engagement protrusion 2
7, the hot water supply lever 16 is locked (see FIG. 2).

At this time, the spring 11 of the hot water supply valve 10 applies a force in the direction of pushing back the hot water supply lever 16, so that a counterclockwise momentum acts on the engagement pawl 20 of the hot water supply lever 16, so that the lock does not come off.

Therefore, the hot water supply valve 10 continues to open the hot water supply port 9.

When releasing the lock, by pressing the rear end of the hot water supply lever 16 downward, a moment is applied in the second country direction using the tip of the chevron rib 30 formed on the side wall of the operating body 17 as a fulcrum, and the hot water supply lever 16 is pressed downward. The rear end portion fits into the step 28 of the faucet lid 12, and the hot water supply lever 16 swings as shown by the dashed line in FIG.

Therefore, the engagement claw 20 and the engagement protrusion 27 are disengaged, and the spring 11 of the hot water supply valve 10 causes the hot water supply lever 16 to disengage.
automatically returns to its original position, and the hot water supply valve 10 closes the hot water supply port 9.

In this manner, the hot water supply valve 10 can be easily opened and closed by simply sliding the hot water supply lever 16 forward when locked, and by simply pushing the rear end of the hot water supply lever 16 when unlocked.

FIG. 7 shows another embodiment of the present invention, in which the hot water supply lever 29 is constructed as an integral part, the shaft portion 23 of the above embodiment is made separate, and after the hot water supply lever is installed in the opening hole 26, the shaft The part 23 cannot be attached or removed.

Note that in FIG. 7, the same parts as in FIG. 1 are designated by the same reference numerals, and explanations thereof will be omitted.

As is clear from the above explanation, according to the present invention, sliding the hot water supply lever locks the hot water supply valve in the open position, while pressing the rear end of the hot water supply lever swings the hot water supply lever. The locking and unlocking operations of the hot water valve can be easily performed, and the structure of the locking mechanism and locking mechanism is extremely simple, and can be compactly housed in a sealed plug that takes up little space. can be stored in.
