Description

[Detailed Description of the Invention] The present invention relates to an electric cooker equipped with a plug-in thermostat.

The purpose of this was to ensure the safety of the appliance by preventing the plug-in thermostat from being attached unless a pot was placed on the heating plate.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes an outer frame of the cooker, which has a plug insertion opening 2 in a part of the side wall.

Reference numeral 3 denotes a heating plate with a built-in heater fixed within the outer frame 1, and a groove 4 is provided in a portion of the heating plate 3 corresponding to the plug insertion opening 2.

Further, at both ends of this groove 4, terminals 14a and 14b for supplying electric power to the heater are provided, as is clear from FIG.

5 is a stopper piece made of an elastic plate, and the end 6 is L.
It is bent to form a shape.

This stopper piece 5 is attached to the groove of the heating plate 3 with a screw 7, and the end 6 is normally positioned so as to close the plug insertion opening 2 of the outer frame 1, as shown in FIG.

Reference numeral 8 denotes a pot, and a heat-sensitive cylinder 9 into which a heat-sensitive rod of a plug-in thermometer (to be described later) is inserted protrudes from the bottom of the pot.

When the pot 8 is placed on the heating plate 3, this heat-sensitive cylinder 9
It is configured to fit into the groove 4 of the heating plate 3.

Reference numeral 11 denotes a plug-in thermometer, which is inserted into the hole 10 of the heat-sensitive cylinder 9 of the pot 8.
It has a heat-sensitive rod 12 that fits with the terminal pins 14a and 14b, and plug portions (not shown) that fit with the terminal pins 14a and 14b.

13 is a power cord connected to the plug-in thermostat 11.

The present invention is as described above, and when the pot 8 is not placed on the heating plate 3, as shown in FIG. Since the plug-in thermostat 11 is located so as to block the plug-in thermostat 11, even if an attempt is made to connect the plug-in thermostat 11 in this state, it will not be possible.

On the other hand, when the pot 8 is placed on the heating plate 3, as shown in FIG.

In this state, the end 6 of the stopper piece 5 comes off the plug insertion opening 2 of the outer frame 1, so the plug-in thermometer 11
can be connected.

As explained above, in the present invention, the heater built into the heating plate cannot be energized unless a pot is placed on the heating plate, resulting in an extremely safe electric cooker.
