Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric hot water storage container, and more particularly to an electric hot water storage container provided with a heater and a circuit box for accommodating an electric circuit in a bottom portion of a body.

[0002]

2. Description of the Related Art Such an electric hot water storage container is widely used as a household electric pot or the like. In addition to pouring in and discharging the content liquid, it is often handled by the water around the sink.

For this reason, it is conceivable that water may invade through the gap around the outside of the body. While handling an electric pot in a sink, it is rare that it is soaked in water stored in a sink or the like placed in a think tank.

In such a case, a large amount of water easily enters from around the bottom of the outer case having many gaps.

When water enters the body as described above, the electric circuit provided in the bottom of the body is damaged.

To cope with this, a circuit box for accommodating an electric circuit is conventionally provided. Initially, this circuit box was opened downward so that it could handle water that had entered and dropped from the top of the body.

However, this cannot cope with the fact that the water soaked in the electric pot enters from below. Therefore, the present applicant has previously provided a form in which the circuit boxes are vertically aligned with each other to form independent chambers.

In this case, as shown in FIGS. 5 and 6, for example, a circuit box e is formed so as to form an independent chamber in the bottom portion of the body g, so that various kinds of electric circuits from the accommodated electric circuit can be obtained. It is difficult to pull out the lead wire. In order to facilitate this, as shown in the figure, a large drawing hole b is provided in the ceiling portion of the container member a which is one member forming the circuit box e, or the other member forming the circuit box e is used. A large gap passage d for drawing out the lead wire is formed between the peripheral walls of a certain lid member b and the container member a which are fitted to each other.

[0009]

However, in such a circuit box e, water which may enter the body easily enters the circuit box e through the outlet hole b and the clearance passage d, so that an electric circuit is formed. I can't protect it from the intrusion of water.

This is provided with a partition such as a heat shield plate h which isolates it from the heater above the circuit box, covers the circuit box e from above, and prevents water falling from above the body. It is possible to deal with it by not going in. However, it cannot be dealt with when a large amount of water enters due to pickling.

Recently, there has also been provided an electric pot in which the inner container is detachable and is detachably mounted on a heater provided at the bottom of the body for use. This type of electric kettle opens the inner part including the heater installation part at the bottom of the body when handling the body when the inner container is removed, so water may spill into the body for some reason. , It is possible that the inner container is mistakenly not removed or that the inner container is not removed and that water is poured into the body. This is a particular problem in the conventional structure as shown in FIG. 6 because there is a dislike for water to enter the bottom of the vessel.

Therefore, the present invention solves the problem caused by water that may enter the bottom of the body without complicating the structure or complicating the work of pulling out or removing the lead wire. It is an object of the present invention to provide an electric hot water storage container that can be eliminated.

[0013]

In order to achieve the above-mentioned object, the present invention provides an electric hot water storage container in which a heater and a circuit box for housing an electric circuit are provided in the bottom portion of the body, and the peripheral walls are connected to each other. Are tightly fitted to each other to form a circuit box, at least one member of a container member and a lid member is provided with a notch cut from an open edge, and an electric circuit is provided between the notch and the peripheral wall of the other member. The lead wire for drawing out the lead wire to the outside is formed in a shape corresponding to the cross section of the lead wire and in a size close to the outer circumference of the lead wire.

[0014]

According to the above structure of the present invention, the lead wire outlet of the circuit box is opened from the open edge formed between the peripheral walls of the container member and the lid member, which form a circuit box by tightly fitting the peripheral walls. Is formed between the notch and the peripheral edge of the other member in a shape corresponding to the cross-sectional shape of the lead wire to be pulled out and in a size in close contact with the outer periphery of the lead wire. Since all the joints formed by the lead wires and the lead wires are in close contact with each other, it is possible to prevent the formation of a gap into which water may enter.

Further, the drawer port is opened to a part of the open edge of the peripheral wall as a notch of the peripheral wall of one member by unfitting the peripheral walls of the container member and the lid member. It is easy to fit the lead wire to the notch and remove it from the notch, and the fitted state is stabilized by the notch, and the peripheral walls of the container member and the lid member are fitted together in this state. The lead-out port can be closed with the lead wire having the above-mentioned shape and size only by pulling out the lead wire.

A tight fit between the peripheral walls of the cover member and the lid member prevents a gap such as water from entering between the container member and the lid member, so that a large amount of water may enter the bottom of the container. Even if there is, it is possible to avoid that this enters the circuit box and damages the electric circuit, thus ensuring the safety of the electric hot water storage container and its use.

Further, the lead-out port is opened to a part of an open edge of the peripheral wall of the one member by releasing the close fitting between the peripheral walls of the container member and the lid member, and the lead wire is opened. Can be easily fitted into or removed from the notch, and the fitted state is stabilized by the notch, and in this state the container member and lid member are placed in a tight fit between the peripheral walls. By simply doing so, the lead-out port becomes the above-mentioned shape and size and can be closed in the state where the lead wire is pulled out.Therefore, the structure is not complicated, and the lead wire pulling out and removing work is simplified, and assembly work and maintenance work are performed. It can be convenient for work.
