Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for heating a stored liquid.
The present invention relates to an electric water heater that maintains heat. 2. Description of the Related Art A conventional electric water heater of this type has a structure as shown in, for example, a partial vertical sectional view of FIG. That is, in FIG. 2, reference numeral 1 denotes a bottomed cylindrical container provided in an exterior body 2, wherein a heating element 3 is fixed to the back side of the bottom surface of the container 1, and a temperature detecting device 4 Is installed. Reference numeral 5 denotes a lid that covers the upper opening of the container 1. The lid 5 includes an inner lid 6 facing the container 1, a rubber packing 7 disposed around the inner lid 6, and an outer lid 8 forming an outer shell.
And a lid cover 9 disposed between the inner lid 6 and the outer lid 8 and a slidable stopper 10 disposed inside the lid 5. The other side is formed by a slidable stopper 10, and the upper opening of the container 1 is sealed openably and closably. [0003] In such a conventional electric water heater, when the lid 5 is opened, the steam attached to the bottom surface 26A of the inner lid 6 becomes water droplets and moves toward the shaft support 12 side. flow,
With the momentum at the time of rotation, it jumps out of the shaft support 12 and
There was a problem that it dripped on the installation surface along the outer surface of the device. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and it is an object of the present invention to provide an easy-to-use electric water heater in which water droplets attached to the bottom surface of an inner lid do not flow out to the outer surface of an outer lid when the lid is opened. It is an object. [0005] According to an aspect of the present invention in order to achieve the above object, the heating element arrangement is and the bottom surface rear exterior body
It has a fixed container, a cover that covers the upper opening of the container and is pivotally supported by the exterior body, an inner cover disposed on the container side of the cover, and a packing disposed around the inner cover. An electric water heater, wherein a lower end surface of the packing projects downward from a bottom surface of the inner lid, and the inner lid is opened when the lid is opened.
The attached water droplets pass through the projecting portion of the packing lower end surface.
In which it has configured to flow into the container. [0006] With such a configuration, since the lower end surface of the packing disposed on the inner lid peripheral portion is formed to protrude below the bottom surface of the inner lid, the water droplets that flow out stop at the packing and flow into the container. Does not flow to An embodiment of an electric water heater according to the present invention will be described below with reference to a longitudinal sectional view of FIG. FIG. 1 shows an embodiment of the present invention.
In FIG. 1, reference numeral 21 denotes a bottomed cylindrical container provided in an exterior body 22. A heating element 23 is fixed to the back of the bottom of the container 21, and a temperature detecting device 24 is mounted to the back of the center bottom of the container 21. are doing. twenty five
Is a lid that covers the upper opening of the container 21. The lid body 25 includes an inner lid 26 facing the container 21 side, a rubber packing 27 disposed around the inner lid 26, an outer lid 28 forming an outer shell, and the inner lid 26 and the outer lid 28.
And a slidable stopper 30 disposed inside the lid body 25. One side is pivotally supported by the exterior body 22, and the other side is formed by a slidable stopper 30. And container 21
The point that the upper opening portion is sealed so as to be openable and closable is the same as the conventional configuration. In the embodiment of the present invention, the lower end surface 27A of the packing 27 provided around the inner lid 26 is formed so as to protrude below the bottom surface 26A of the inner lid 26. In the structure shown in FIG. 1, when a liquid is contained in the container 21 and the energization is started, the heating element 23 is heated to heat the liquid in the container 21 and a temperature detecting device mounted on the lower part of the container 21. The detection temperature of 24 also rises, and when the set value is reached, the power supply is stopped. When the hot water in the heated container 21 is discharged by a pump or the like and the hot water in the container 21 is exhausted, the stopper 30 of the lid 25 is disengaged, and the lid 25 is pivotally connected to the exterior body 22. The container 21 is opened using the pivot 32 as a fulcrum, and water is poured into the container 21. As described above, according to the electric water heater of the present invention, the lower end face of the packing disposed on the inner lid peripheral portion is
Even when water droplets attached to the bottom surface of the inner lid during heating or heat retention flow out of the inner lid bottom surface when the lid is opened after heating, the water droplets flow Are blocked by these formations and flow into the container without flowing to the exterior body. As a result, when the lid is opened and closed during use, water droplets can be prevented from dropping on the installation surface.
