An electrical circuit provided in a part of the bottom body of the body to centrally wire the main parts of the electric circuit for operation and display on one circuit board and to install this in the bottom space of the body. I am trying to house it in a box.

This is an electric circuit box integrally formed on a part of the electric circuit box by utilizing the fact that the bottom body is a member made of synthetic resin which is joined to the lower end of the exterior body of the container. Adopts a shape that opens downward to protect the electric circuit on the circuit board from leaking water from the top of the container, dripping of condensed water, or heat from the heater provided at the bottom of the inner container. is doing.

On the other hand, as is known from Japanese Utility Model Laid-Open No. 3-84029, water leakage or dew condensation that has occurred inside the body or water that has penetrated through a gap between parts outside the body to the outside of the body. It is also practiced to actively provide drainage holes and gaps for draining.

[0005]

However, due to the use and handling of the electric hot water storage container, it may be placed in a sink tank in a kitchen sink, a wash tub placed on the sink tank, or water contained in or accumulated in other containers. The bottom of the electric hot water storage container may be inadvertently pickled.

In such a case, the above-mentioned water collectively enters into the body through the drain holes or gaps provided at the bottom of the body, and the invading water scatters into the electric circuit box and is placed on the circuit board. This causes the inconvenience that the electronic parts and circuits get wet.

Even if there is no water pool, the water spills,
Alternatively, if the electric hot water storage container is placed on the surface of a scattered sink or the like, the stationary portion of the body gets wet and water adheres. This adhered water sometimes travels into the stationary portion of the body due to the fall of the body, and reaches the electronic parts and circuits in the electric circuit box to adversely affect them.

[0008] Therefore, an object of the present invention is to provide an electric hot water storage container having a structure capable of ensuring the safety of an electric circuit provided in an electric circuit box even if there is such intruding water.

[0009]

In order to achieve the above-mentioned objects, the present invention provides an electric machine in which an electric circuit box having a downward opening is provided in a part of a bottom body of a container for accommodating and holding an inner container. In the hot water storage container, a waterproof cover that covers the opening of the electric circuit box from below and fits so that the upper edge of the peripheral wall is higher than the opening edge of the electric circuit box is provided. Installed with a space between the cover and the electric circuit box, or between the peripheral walls of the cover and the electric circuit box, or at least one peripheral wall above the bottom of the cover, a ventilation part communicating with the inside and outside of the electric circuit box is provided. This is the main feature.

The ventilation portion formed between the cover and the electric circuit box may also serve as a lead-out port for connecting a lead wire for connection with another electric circuit provided in the electric circuit box.

[0011]

In the above-mentioned structure, which is the main feature of the present invention, the bottom of the body may be soaked in the accumulated water or the like, and the water may collectively enter the bottom of the body and may be scattered around. However, the electric hot water storage container is placed on the surface of the sink where the water is spilled or scattered and the stationary part of the body gets wet and water adheres. Even if it gets into the bottom of the body, the cover that covers the lower opening of the electric circuit box from below is installed with a space between it and the stationary part of the body. Water that has invaded and scattered around, or that has flowed into the bottom of the vessel is hard to reach the cover, and even if it reaches the cover, the bottom of the cover ensures that the water will enter the electric circuit box as it is. Shut off and above the electrical box opening in the cover Is installed between the peripheral wall reaching the upper part and the electric circuit box, or at least one peripheral wall of the cover and the electric circuit box is provided with a ventilation part that communicates with the inside and outside of the electric circuit box, and the electronic parts generate heat inside the electric circuit box. Even if you do so, while ventilating the inside and outside through the ventilation part to promote cooling for thermal safety, this ventilation part is above the bottom part of the cover and only in a specific place, so the bottom part of the cover is Even if the water reaches even a small amount, the probability that it will reach the ventilation part is minimized, water is fully prevented from entering the electric circuit box, and the electronic parts and circuits in the electric circuit box are protected from water. Performance is improved.

Further, in the structure in which the ventilation part formed between the cover and the electric circuit box also serves as a lead-out port for connecting a lead wire for connection with other electric circuits provided in the electric circuit box, Without specially providing a wire outlet or performing special work, simply cover the electric circuit box with the cover and fix it, and the electric circuit inside the electric circuit box and the electric equipment and electric circuit outside the electric circuit box It is possible to connect with the lead wire.
