DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric water heater capable of heating and keeping a liquid contained therein and pouring the liquid into an external container.

[0002]

2. Description of the Related Art When an electric water heater is used, the inner surface of a container is often stained due to adhesion of water scale, adhesion of scale, etc. by boiling the water.
There is a configuration in which the container portion is detachable so that the inner surface of the container can be easily cleaned, and the container can be directly washed with a sink or the like.

FIG. 2 is a longitudinal sectional view showing the structure of a conventional electric water heater. As shown in FIG.
Can be set in the main body 102, and the lead-out path of the liquid in the container can be set from the outlet 103 at the bottom of the container to the bushing 104.
Through the water pipe 107 in the cover 106 and again from the discharge port 108 in the main body to the outside of the container. At the time of tapping, the push plate 109 of the lid was operated to send air into a bellows (not shown) to increase the internal pressure and push out the hot water.

[0004]

However, the above configuration has the following problems when the lid is opened.

(1) At the time when the lid is opened, the connection portion of the lead-out path with the lid is opened upward and becomes dirty with dust and the like in the air. It was hygiene.

(2) Also, when the hot water outlet method is not based on the bellows of the lid (for example, a pumping method using an electric pump), even if the lid is removed, the electric pump operates by mistake and the hot water is unexpectedly opened. There was a risk of burns, wetting the floor, hot water flowing into the charged part of the body, etc. from the connection part in the state.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide an electric water heater that is not unsanitary, is safe, has good operability, and has few failures.

[0008]

SUMMARY OF THE INVENTION According to the present invention, there is provided a container having a liquid container detachably attached to a main body having an open upper end, a lid for covering the upper surface of the container, and a supporting portion which is engaged with a flange at the upper end of the container. It has a mouth, a handle provided in the vicinity of the spout, and a lead-out path for leading the liquid out of the container without passing through the lid from the container.

Further, the discharge path is provided with a discharge port having a built-in fall-out prevention valve, the discharge path is formed integrally with the container, and is detachable from the main body.

[0010]

According to the present invention, a container detachable from the main body is provided.
Because the lead-out path that leads the contained liquid out of the vessel without passing through the lid from the container is provided integrally,
Even if the lid is left open when the container is attached or detached, dust and the like in the air can be prevented from entering the lead-out path and becoming dirty or unsanitary.

Further, a discharge port having a built-in overturn prevention valve is provided in the lead-out path to eliminate the connection portion and to be integrally formed with the container, so that unexpected hot water can be prevented from flowing out of the connection portion.
Even if the main body falls, the built-in fall-out prevention valve operates at the discharge port of the lead-out path, which can prevent hot water from flowing out of the container, and is excellent in safety and hygiene.

[0012]

FIG. 1 is a longitudinal sectional view showing an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a substantially cylindrical container which has a closed bottom and is open upward, and a flange 2 at an upper end of the container 1 has a handle (not shown) which is held when detached via a container packing 3.
Is supported by the spout 4 provided with

A waterproof fitting 5 is provided below the container 1 and is connected to a water pipe 7 via a bushing 6 to form a part of a lead-out path 8.

In FIG. 1, a discharge port 10 having a built-in overturn and outflow prevention valve 9 is provided at the end of the water pipe 7, leading to a discharge pipe 11 at the tip.

The falling outflow prevention valve 9 is normally lowered, but when the body falls, the falling outflow prevention valve 9 moves to a narrow portion 10a in the discharge port 10 to block a passage there and supply hot water. Prevent spill.

This portion forms one unit (container unit), and when the container is attached and detached by holding the above-mentioned handle, it is detached from the main body together.

As described above, in the present embodiment, the lead-out to the outside of the container in the container is performed via the lead-out path 8 from the container 1 to the outside of the container without passing through the inside of the lid 31.

In FIG. 1, a heating element 23 is provided below the inner frame 22 of the main body 21, and a sensor 24 is provided in the center in an upwardly urged state so as to be vertically movable. At this time, the sensor 24 comes into close contact with the bottom of the container, detects the temperature of the liquid in the container, and controls the heating element 23 by the control circuit 25. The sensor 24 also detects whether the container 1 is set. That is, when the container 1 is not set, the sensor 24 jumps out upward because there is no load from above, and at this time, the limit switch (not shown) is operated so that the current cannot be supplied.

Reference numeral 26 denotes a body that wraps the inner frame through a space, and 27 denotes an upper frame mounted on the body 26, which holds the body together with a lower hook 28.

The lid 31 placed on the above-mentioned spout 4 is
It is supported by a hinge. Inside the lid, there is a bellows (not shown) for sending air into the container, and the hot water in the container is sent out of the container with the operation of the push plate.

Here, the type having the bellows in the lid has been described, but the same applies to the case of tapping by an electric pump or the like.

[0023]

As described above, the electric water heater of the present invention is provided so as to reach the outside of the container without passing through the lid via the lead-out path from the container accommodating the liquid detachable from the main body. Even if the lid is left open,
It is possible to prevent dust and the like in the air from entering the lead-out path and becoming dirty or unsanitary.

Further, the discharge path is provided with a discharge port having a built-in fall-off prevention valve, is formed integrally with the discharge path and the container, and is configured to be detachable from the main body. No water leaks out of the container even if the main unit falls, and prevents dust and other foreign matter from entering the path when the lid is opened. ing.

As described above, according to the present invention, an electric kettle excellent in operability and safety can be provided at low cost.
