Description of the Related Art Conventional electric kettles that have a bellows inside the lid and discharge the liquid in the container by the pumping action of the bellows are located in the lower part of the container and are designed to control heating elements. The parts were arranged.

られていた。Further, in recent years, the control part tends to be electronic, which requires a substrate for an electronic circuit that occupies a relatively large area, and this substrate for electronic circuit is installed below the container of the electric water heater. When installed, this electronic circuit board occupies most of the area under the container.
When the electric pump for discharging hot water in the container is installed below the container, it cannot be located on the same plane as the electronic circuit board. Therefore, in the conventional case, the electric pump is first installed below the container. Then, a two-stage structure was adopted in which an electronic circuit board was installed below the electric pump.

いう問題点を有していた。However, in such a conventional configuration, when the electric pump is installed below the container, the two-stage configuration with the electronic circuit board increases the storage space below the container, The body that stores these becomes large. In this case, by installing an electric pump below the container,
Since the bellows inside the lid is not required, the lid itself can be made thinner, but it does not lead to a compact electric water heater as a whole, and the large body described above increases the material cost and handles it easily. It had the problem of becoming inconvenient. Further, in the wiring, since the electric pump and the electronic circuit board have a two-stage configuration, the distance between the terminal portion of the heating element provided on the outer side of the bottom surface of the container, the electric pump, and the electronic circuit board increases, There is a problem that the wiring work is difficult to perform and the design cannot be made compact.

部に設置してなる電気湯沸し器とする。Means for Solving the Problems In order to solve the above problems, the present invention has a bottomed cylindrical container, a heating element provided outside the bottom surface of the container that heats the liquid in the container, and downward from the bottom surface of the container. A composite that accommodates a hanging heating element terminal portion, an electric pump that is provided below the heating element and discharges the liquid in the container to the outside of the body, and a circuit board that controls the heating element and the electric pump. A case made of resin and a body for accommodating the respective components are provided. The case is a container mounting member provided below the heating element, and two case mounting portions located on the center line of the container bottom. And the case mounting portions at the two locations are positioned substantially parallel to the terminals of the heating element, and the case is provided so as to cross diagonally between the two case mounting portions. , The heating element terminal portion The electric pump has a shape in which a portion located below is cut out, and the electric pump is installed in a space portion other than the mounting portion of the case on the same plane as the case.

In addition, since the portion facing the terminal of the heating element is cut out, it is the longest in the longitudinal direction and the width excluding the terminal portion of the heating element is the longitudinal direction of the case. Since it can be extended at a right angle, the area of the case can be increased. Further, as a result, a mounting space for the electric pump is secured, so that the case and the electric pump can be arranged on the same plane, and as a result, the entire electric water heater can be made compact.

利となるものである。EFFECTS OF THE INVENTION As is clear from the description of the above embodiments, in the electric water heater of the present invention, the case that houses the circuit board that controls the heating element and the electric pump is located substantially parallel to the terminal portion of the heating element. In addition, since it is provided so as to cross diagonally between the two case mounting portions and the portion of the heating element facing the terminal is cut out, it becomes the longest in the longitudinal direction and has the width. Since the portion of the heating element excluding the terminal portion can be extended at right angles to the longitudinal direction of the case, the area of the case can be increased. This also secures a mounting space for the electric pump, so that the case housing the control board on the same plane, the electric pump, and the terminal portion of the heating element provided on the bottom surface of the container can be arranged. By providing the pump below the container, the bellows of the lid that is required in the past is no longer required, and the lid can be made thinner, resulting in a very compact electric water heater as a whole. Since it becomes a body, the body for accommodating each of the above-mentioned components is also downsized, the cost of the material can be reduced, and the miniaturization makes it very convenient to carry.
