In this embodiment, the bottom plate portion 11 of the main body 1 is
The convex plate portion 50 is provided on the upper surface, and the convex portions 24 and 25 are provided on the bottom surface 2a of the main body case 2, respectively. When mounting the main body case 2 on the bottom plate portion 11, the following procedure is performed.

That is, first, the rear bottom surface 2a of the main body case 2 is placed on the front side of the convex plate portion 50, and the convex plate portion 50 is formed between the inner side surface portions 25b, 25b of the rear convex portion 25 of the main body case 2. Positioning is performed so that the vertical left and right side surfaces 50b, 50b enter. When performing the alignment, the alignment can be easily performed by making the front side shorter than the rear side in the width between the substantially vertical left and right side face portions 50b, 50b of the convex plate portion 50. .

After the alignment is completed, the main body case 2 is pushed in by pushing the front side surface of the main body case 2 rearward with the main body case 2 placed on the convex plate portion 50. Then, the inner side surface portions 25b, 25b of the rear convex portion 25 of the main body case 2 are
And the inner side surface portion 2 of the front convex portion 24 of the body case 2 as well.
4b and 24b are substantially vertical left and right side surface portions 5 of the convex plate portion 50.
Guided by 0b and 50b, it can be pushed straight back without shifting in the left-right direction. In this case, it can be performed without the front convex portion 24, but the presence of the front convex portion 24 can reduce the displacement in the left-right direction.

When the main body case 2 is pushed in, the rear convex portion 25 of the main body case 2 comes into contact with the protruding piece 51 which is provided on the left and right side surface portions of the convex plate portion 50 so as to project in the left and right direction.
If you push the main body case 2 regardless, the main body case 2
The inclined bottom surface portion 25a of the rear convex portion 25 rides on the inclined front surface 51b of the protruding piece 51 and is pushed rearward. And finally, the inclined bottom surface portion 2 of the rear convex portion 25 of the main body case 2

Since it is in contact with the main body case 2, the main body case 2 remains horizontal. However, when the main body case 2 is removed from the bottom plate portion 11 and placed on a horizontal surface such as a sink, the main body case 2 becomes higher on the rear side where the heater insertion hole 21 is present, so that the water put in the main body case 2 is It is possible to prevent spilling from the heater insertion hole 21 due to vibration.

Further, it has been explained that the substantially vertical front surface 25c of the rear convex portion 25 of the main body case 2 and the substantially vertical rear surface 51c of the projecting piece 51 are in contact with each other to function as a stopper. The rear surface 51c does not necessarily have to be substantially vertical, and may be a more obtuse angle as long as it has a stopper function.

FIG. 6 shows a modification of the first embodiment. First
Although the convex plate portion 50 of the embodiment has been described as a flat plate, the upper surface portion 50a does not need to have such a flat plate area, and the point is that the upper surface portion 50a is on the bottom surface 2 of the main body case 2.
Since it suffices that it has a width that allows it to move in the front-rear direction while a is in contact with it, the convex portion at the center of the upper surface portion 50a is omitted,
Two convex plate parts 50, 50 extending in the front-rear direction on the left-right side are provided.

By forming in this way, the contact area between the upper surface portion 50a of the convex plate portion 50 and the bottom surface 2a of the main body case 2 can be reduced, the movement of the main body case 2 can be made smooth, and the main body case 2 can be smoothly moved. The heat conduction from the bottom of the case is reduced and the temperature rise on the floor can be suppressed. Further, the convex portions 24 and 25 of the main body case 2 and the convex plate portion 50 side surface portion 50
Since the guide portion with b can be performed on the inner side surfaces of the two convex plate portions 50, 50, the convex portion 2 of the main body case 2
The mounting positions of 4 and 25 can be appropriately selected.
