It has a saucer-shaped soup tray and a body provided with a mounting hole for holding the peripheral edge of the hot plate holder, and when the hot plate holder is attached to the body, the hot plate holder can be attached to the body through the mounting hole provided in the body. At the same time, place the periphery of the hot plate holder on the upper surface around the mounting hole, and place the stopper fixed to the hot plate holder on the lower surface side around the mounting hole of the body. The hot plate receiver was attached to the body by bending it.

However, in the above conventional configuration, when the hot plate holder is attached to the body, the periphery of the hot plate holder is placed on the upper surface around the mounting hole of the body, so the periphery of the hot plate holder and the body are There is no gap between the mounting hole and the upper surface, and as a result, the hot air inside the body cannot escape to the outside, causing the problem that electrical components inside the body deteriorate due to high heat. Was. In addition, since the periphery of the hot plate holder is only placed on the top surface of the periphery of the mounting hole of the body, if an impact is applied to the hot plate holder, the hot plate holder rotates relative to the body, causing a spiral. Another problem was that the position of the heating element fluctuated.

Purpose of the Invention In view of the above-mentioned conventional problems, the present invention makes it possible to prevent thermal deterioration of electrical components in the body by considering the mounting structure of the hot plate holder to the body. It is an object of the present invention to provide an electric stove in which the position of a spiral heating element does not change even when an impact is applied to the electric stove.

Structure of the Invention In order to achieve the above object, the present invention provides a hot plate support to which a spiral heating element is attached and a positioning metal fitting is attached to the rising edge of the periphery; A body is provided with a rising part having a notch around the hole, and a peripheral edge part protruding outward is provided at the upper end of the rising part of the hot plate support, and this peripheral edge part rests on the rising part of the body. , and the positioning metal fittings are fitted into the notches of the body, and then the stopper metal fittings are bent to the lower surface side around the mounting hole of the body. According to this configuration, the peripheral edge of the hot plate receiver is fitted into the notch of the body. At the same time, the positioning metal fitting fixed to the rising edge of the hot plate holder is fitted into the notch in the rising edge of the body, so that there is no space between the rising edge of the body and the periphery of the hot plate holder. As a result, the hot air inside the body can escape to the outside of the body through this gap, eliminating the problem of thermal deterioration of electrical components inside the body. The positioning metal fitting fixed to the peripheral edge of the hot plate holder is fitted into a notch in the rising part of the body, so even if an impact is applied to the hot plate holder, the hot plate holder will not rotate relative to the body. As a result, the problem that the position of the spiral heating element fluctuates can also be solved.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 7. In the figure, 1 is a box-shaped body, and a mounting hole 2 is provided in the center of the top surface of the body 1 as shown in FIG. A rising portion 4 having a plurality of notches 3 is provided. Reference numeral 5 denotes a hot plate support which is punched and formed leaving only the peripheral edge at the bottom, and a peripheral edge part 7 is provided at the upper end of the peripheral rising part 6 of this hot plate support 5 to project outward. 8
is a recessed portion formed by pushing out a part of the peripheral edge rising portion 6 of the hot plate support 5, and a rectangular slit 9 is provided in the vertical direction at a position opposite to this recessed portion 8. Reference numeral 10 indicates a positioning metal fitting having an inverted L-shaped cross section and is fixed to the outside of the recess 8, and reference numeral 11 indicates a hot plate support 5 which is shifted in position from the positioning metal fitting 10.
A plurality of fasteners are fixed to the outer side of the peripheral edge rising portion 6, and these fasteners 11 are fixed obliquely as shown in FIG.

A heating element 12 is a sheathed heater formed in a spiral shape, and both ends of the heating element 12 are bent downward from the spiral part 13 and protrude outside the outer shape of the spiral part 13. As shown in FIG. 1, this heating element 12 is fixed to the upper surface of one central support metal fitting 14 and two side support metal fittings 15 to form a heater unit. In order to attach the heater unit to the hot plate receiver 5, as shown in FIG. The heater unit is attached to the hot plate receiver 5 by passing the tip through the slit 9 of the hot plate receiver 5 and passing the wire 19 through the wire attachment hole 18 provided near the tip of the narrow portion 16. In this state, when the upper periphery of the saucer-shaped soup tray 20 is installed on the bottom periphery of the hot plate holder 5 and the heater unit is lowered, the force of the compression coil spring 17 is applied to the other end of the central support fitting 14. protrusion 2
1 enters the recess 8 of the hot plate receiver 5 and is fixed.
Then, the protrusion 21 and the two side support fittings 1
When the three points 5 contact the upper periphery of the juice pan 20 installed on the hot plate receiver 5, the narrow part 16 of the central support fitting 14 comes into contact with both the upper and lower ends of the slit 9 of the hot plate receiver 5. It is held in a position where it does not come in contact with the
Due to the abutment of the points, the heater unit can be installed in the soup tray 20 in a stable state without wobbling.

A unit in which the heating element 12, supporting metal fittings 14 and 15, hot plate receiver 5, and juice tray 20 are integrated is called body 1.
When installing the unit into the mounting hole 2 of the body 1, the unit is dropped into the mounting hole 2 of the body 1 so that the positioning metal fitting fixed to the peripheral rising part 6 of the hot plate support 5 fits into the notch 3 provided in the rising part 4 of the body 1. Then, the unit is attached to the body 1 by bending the stopper 11 to the lower surface side around the attachment hole 2 of the body 1 as shown by the dotted line in FIG. With this attachment, the peripheral edge 7 of the hot plate receiver 5 is placed on the upper surface of the rising part 4 of the body 1, as shown in FIG. A gap is formed between 7 and 7. Therefore, the hot air inside the body 1 exits the body 1 through this gap, and
The air entering the body 1 from the lower part of the body 1 exits the body 1 through the gap, thereby effectively cooling the electrical components (not shown) installed in the body 1. It is something that can be done. Further, since the positioning metal fitting 10 fixed to the peripheral edge rising portion 6 of the hot plate support 5 fits into the notch 3 provided in the rising portion 4 of the body 1,
Even if a shock or the like is applied to the hot plate holder 5, the hot plate holder 5
There is no possibility that the body 1 will rotate relative to the body 1. Furthermore, when the heating element 12 is attached to the hot plate support 5, the slit 9 of the hot plate support 5 through which the narrow portion 16 of the central support fitting 14 passes has a margin with respect to the narrow portion 16. When removing the heating element 12 from the hot plate holder 5, it can be easily removed by rotating the other end of the central support fitting 14 in the counterclockwise direction. 5 and can be easily removed for cleaning.

Effects of the Invention As described above, according to the present invention, the peripheral edge of the hot plate support is placed on the upper surface of the rising portion of the body, and the positioning metal fitting fixed to the peripheral rising portion of the hot plate support is placed on the rising portion of the body. Because it is fitted into the notch, a gap is formed between the rising part of the body and the peripheral edge of the hot plate holder, and as a result, hot air inside the body flows outside the body through this gap. This eliminates the problem of thermal deterioration of electrical components inside the body, and since the positioning metal fittings fixed to the peripheral edge of the hot plate holder are fitted into the notches in the rising part of the body, heat can be removed. Even if an impact is applied to the plate holder, the hot plate holder will not rotate relative to the body, and as a result, the problem of the position of the spiral heating element changing can be solved. be.
