DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a hot plate,
The present invention relates to a cooking device such as a grill pan and a grilling device.

[0002]

2. Description of the Related Art A general cooking device such as a hot plate includes a cooking plate in which a heating element such as a sheathed heater is integrally housed at a bottom portion, and a plug-in thermometer electrically connected to a terminal portion of the heating element. It prepares various kinds of cooking by heating the heating element.

In addition, when the cooking device is washed with water in order to remove cooked foods and the like after cooking, the water enters the charging portion of the main body case in which the terminal portion of the heating element is disposed, and thereby, the insulation inside the charging portion is reduced. There was a risk of performance degradation. In addition, since it is difficult to wipe off the water remaining in the charging section, the water remaining in the main body case causes corrosion. Therefore, as a countermeasure, a structure in which a detachable waterproof cover is provided on the charging section is disclosed in Japanese Utility Model Publication No. 59-2.
No. 6917 is proposed.

On the other hand, even if the plate of such a heating cooker is detached from the main body case, the heating element can be connected to the plug-in thermostat to supply electricity, so that the main body case is heated and the main body case is placed. There was a risk of scorching of the table and fire.

[0005]

However, since the waterproof cover described in the prior art is to be attached to and detached from the charging section each time it is used, the attaching and detaching operation is troublesome, and the waterproof cover may be lost. Was.

[0006] Japanese Utility Model Publication No. 59-26917 discloses:
It is disclosed that a shield is provided in the opening, but in this case, when washing with water, when the shield is hooked with a scrubber or the like, the shield may shift and water may enter the charged part, A sufficient waterproof effect was not obtained.

Further, in such a plug-in thermo-heating cooker, since the distance between the end of the plate and the terminal of the heating element is short, the temperature of the terminal tends to rise due to the heat conduction of the plate. In addition, due to the heat generated by the contact resistance between the terminal and the plug-in thermometer, the temperature of the terminal has abnormally increased, and the heating and burning often occurred.

This is an opening and closing mechanism that can perform an opening and closing operation of the shield 9.

In FIG. 6, the opening / closing mechanism according to the second embodiment has a sliding plate 13 disposed in the shielding case 6 so as to contact the left side surface of the rib 9a. The slide plate 13 is
It is movable in the horizontal direction, and is urged leftward by the urging force of the spring 11 in the state shown in FIG. The guide plate 8 is formed with an inclined surface 8a at a portion in contact with the slide plate 13 so that the width increases from the upper end portion to the lower portion. In addition, the slide plate 13 is a shield case 6
6 is attached to the body case 1 by the guide plate 8 in FIG.
In the direction of arrow A.

Then, as shown in FIG. 7, when the plate 3 is mounted on the main body case 1, the slide plate 13
The slide plate 13 slides to the right by sliding against the inclined surface 8a of the
1 is turned against the urging force. Then, at the same time, the shield 9 also rotates, and the insertion port side of the plug-in thermo 12 is opened.

On the other hand, when the plate 3 is removed from the main body case 1, the shield 9 closes the insertion port side of the plug-in thermometer 12 by the urging force of the spring 11, and the slide plate 13 slides to the left by the rib 9a. To return to the state of FIG. In this state, the waterproof structure in the shield case 6 is waterproofed by the O-ring 5 and the seal packing 10.

Next, the back surface of the plate 3 shown in FIG.
The operation when the camera is mounted on the main body case 12 in the upward state will be described with reference to FIGS.

FIG. 8 shows a state in which the heating element 3 integrally formed with the plate 3 is connected to the shield case 6. Even in this state, when mounted on the main body case 1, the slide plate 1
3 slides in the direction of arrow A, and the shield 9 is opened as described later.

As shown in FIG. 9, when the plate 3 is mounted on the main body case 1, the slide plate 13 comes into contact with the inclined surface 8a of the guide plate 8 and slides, so that the slide plate 13 moves rightward. By sliding, the rib 9a is rotated against the urging force of the spring 11. Then, at the same time, the shield 9 also rotates, and the insertion port side of the plug-in thermo 12 is opened.

[0031]

The cooking device according to the present invention has the following effects. According to the first aspect, the plug-in thermometer can be inserted into the connection body only when the connection body with the plate attached thereto is attached to the main body case, and when the connection body is removed from the main body case, the plug insertion port is closed. Therefore, the plug cannot be inserted. This eliminates the need to attach the waterproof cover to the connection body and detach it every time it is used, and it is possible to wash the water with confidence while the heating element and the plate are still attached to the connection body.

According to the second aspect, the plug insertion opening can be opened by attaching the connecting body to the main body case.

According to the third aspect, when a plate that can use both the front surface and the back surface is used, the shield is opened and closed even if the connection body on which the plate is mounted is turned upside down and attached to the main body case. be able to.

According to the fourth aspect, at the time of washing with water, it is possible to prevent water from entering the connection body from between the plug insertion port and the shielding plate.

According to the fifth aspect, it is possible to reduce the size of the connecting body without the shield becoming an obstacle when the plug is attached and detached.

According to the sixth aspect, when the connecting body is attached to the main body case, the guide plate can reliably slide the slide plate.

According to the seventh aspect, at the time of washing with water, it is possible to prevent water from entering the connecting body from between the heating element and the shielding plate.

According to the eighth aspect, since the shield is provided inside the connection body, it is possible to prevent a problem that the shield is shifted and opened by contact with the shield during washing or other handling.
