Description

[Detailed description of the invention] The present invention relates to an electric kettle, and more specifically, to an electric kettle with a sealed structure, which has a steam port that is closed by a water stop ball when it falls over, and a hot water supply valve that opens and closes the hot water supply port. .

In general, electric kettles with a sealed structure include those with a screw-type seal and those with a hot water supply valve material seal.

In the former case, since the mouth of the container is opened all around when hot water is poured out, it is not necessary to provide an air intake port, but opening and closing the stopper is troublesome.

In particular, when the container opening has a large diameter, the opening/closing torque becomes large.

In the latter case, opening and closing the tap is easy, but without an air intake, hot water cannot be poured out smoothly.

For this reason, it is necessary to provide an air intake separately from the steam vent, but this has the disadvantage that if the electric kettle is accidentally tipped over, hot water will leak out from the air intake.

The present invention was devised in view of these drawbacks, and its purpose is to provide an electric kettle in which the air intake also functions as a steam vent, and there is no fear of hot water leaking even when the kettle falls over.

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

In FIGS. 1 and 2, 1 is a tapered body whose diameter gradually becomes smaller toward the top; 2 is a shoulder body that is placed and fixed on the upper end of the body 1 and integrally forms a pouring pipe 3; 4 is a handle whose upper and lower ends are fixed to the shoulder body 2 and the body 1; 5 is the body 1;
It is an inner container that is housed and fixed inside the electric kettle and is equipped with a heater (not shown) at the bottom, and these parts constitute the electric pot body.

The upper end of the inner container 5 is tightly fixed to the shoulder body 2 via a packing 6.

Reference numeral 7 denotes a seal stopper detachably attached to the shoulder body 2, and the seal stopper 7 is constructed by integrating a stopper body 8, a stopper lid 18, and a stopper bottom plate 21.

The plug body 8 has a hot water supply port 9 communicating with the hot water pouring pipe 3, and is provided with a hot water supply valve 10 for opening and closing the hot water supply port 9 inside.

This hot water supply valve 10 consists of a valve stem 11 having a valve body 12 at one end, and an operating shaft 15 that presses the valve stem 11 via a slider 14. The valve stem 11 closes the hot water supply port 9 by a spring 13. The operating shaft 15 is also urged rightward in FIG. 1 by the spring 16, and its press button 17 protrudes from the side surface of the handle 4.

By pressing this push button 17, the hot water supply valve 10 opens the hot water supply port 9, making it possible to pour hot water.

A lock lever 19 is slidably attached to the lower surface of the lid 18 and is biased toward the right in FIG. 1 by a spring 20. At the same time, the engaging claw 19b of the lock lever 19 projects from the side surface of the plug body 8.

In the seal plug 7 having the above structure, the protrusion 8a protruding from the hot water supply port side of the plug body 8 is engaged with the stepped portion 2a on the inner surface of the pouring pipe 3 of the shoulder body 2, and the engaging claw 19b of the lock lever 19 is connected to the shoulder body 2. It is attached to the shoulder body 2 by engaging with an engagement recess 2b provided in a position symmetrical to the pouring pipe 3 of the body 2.

At this time, the lower surface of the outer periphery of the stopper plate 21 is crimped to the gasket 6 to seal the inner container 5.

The seal plug 7 has one steam port 22 as shown in FIG.
is provided.

This steam port 22 is composed of a ventilation hole 23 provided in the stopper lid 18, a cylindrical body 24 hanging vertically from the stopper lid 18, and a mounting table 26 protruding from the stopper body 8. A water ball 27 is movably housed.

There are four vertical ribs 25 at 90° intervals on the inner surface of the cylinder 24.
is installed protrudingly.

On the other hand, the mounting table 26 is composed of a plurality of protrusions, and even when the water stop ball 27 is placed on the mounting table 26, the inside of the inner container 5 is connected to the outside air through the minute gaps between these protrusions. are communicating.

Further, on the inner surface of the steam port 22 on the hot water supply port side, a part of the vertical rib 25 is cut out, and a recessed part 28 is formed by the cutout part and a part of the mounting table 26.

When the electric kettle stands upright, the water stop hole 27 is stably placed on the mounting table 26 as shown in FIG. This prevents the vapor pressure inside the inner container 5 from increasing.

Now, if the electric pot accidentally falls over, the hot water in the inner container 5 will flow into the steam port 22, but the water stop ball 27 will hit the vertical rib 2.
5 and closes the ventilation hole 23 as shown in Fig. 4, so no hot water leaks out.

In particular, since the electric kettle always falls in a direction other than the protruding direction of the pouring pipe 3, there is no fear that the water stop ball 27 will fit into the recess 28 as shown in FIG. 5, and leakage of hot water can be completely prevented.

To pour hot water, the electric kettle is tilted toward the hot water inlet by holding the handle 4, and the push button 17 is pressed to open the hot water inlet 9 with the hot water valve 10.

At this time, the water stop ball 27 is inserted into the recess 2 as shown in FIG.
8 and is held, the steam port 22 becomes freely ventilable, air is taken into the inner container 5 through the steam port 22, and hot water can be poured smoothly.

When the electric kettle is returned to its upright position, the water stop ball 27 rolls on the slope of the recess 28 and returns to the mounting table 26.

As described above, according to the present invention, a recess is provided inside the steam vent to hold the water stop hole when the electric kettle is tilted toward the hot water supply port, so that the steam vent does not close. Air is taken in from the steam vent to enable smooth pouring, and the steam vent is reliably closed by the water stop ball in the event of a fall, so the function as a steam vent is not impaired in any way.

Therefore, there is no need to provide a separate air intake as in the conventional case, the structure can be simplified, and hot water can be prevented from leaking when the device falls over.
