BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot plate heated by an electric heater, and more specifically, a hot plate is placed on a mounting surface such as a table with a rug such as newspaper to prevent oil stains. Even in the case, the ventilation hole formed in the outer peripheral portion of the bottom portion of the main body case of the hot plate, in addition to the main purpose to prevent melting damage of the main body case, so as not to be blocked by the rug, The present invention relates to a hot plate with an improved mounting structure for a heat shield plate.

[0002]

2. Description of the Related Art Heretofore, as a hot plate of this type in which a vent hole formed in a bottom portion of a main body case is not covered with a rug such as newspaper, Japanese Patent Laid-Open Publication No. 6-1 is known.
The one described in Japanese Patent No. 54097 is known.

The hot plate described in the above publication has at least a substantially dish-shaped main body case, an electric heater provided in the main body case through a substantially dish-shaped heat shield plate, and can be put in and taken out on the electric heater and the heat shield plate. And a plurality of legs vertically provided on the outer peripheral portion of the bottom portion of the main body case, wherein a plurality of ventilation holes are formed at the bottom portion of the main body case and the protrusions are provided vertically. is there.

Therefore, when the hot plate having the above-mentioned structure is used, the hot plate is placed on a mounting surface such as a table, and when the electric heater is energized, the heater heats the bottom surface of the plate to cover the inside of the plate. The food is heated. On the other hand, the heat from the electric heater is conducted and radiated not only to the plate but also to the heat shield plate, so that the inside of the main body case is also heated. The heated air in the space between the main body case and the heat shield plate is cooled by the outside air introduced from the ventilation hole formed at the bottom of the main body case, and is above the outer periphery of the space between the main body case and the heat shield plate. Is released to. Therefore, the main body case is not abnormally heated.

In addition, since the bottom of the main body case has a plurality of ventilation holes as well as the projections, even if a rug such as newspaper is laid on the mounting surface and a hot plate is placed,
The protrusion controls the floating and bending of the rug, and the vent hole is not blocked by the rug, and the outside air smoothly flows into the vent hole. Therefore, the heated air in the space between the main body case and the heat shield plate is discharged to the upper part of the outer circumference of the space as described above, and the main body case is prevented from being melted and damaged without abnormal heating.

The heat shield plate described in Japanese Patent Laid-Open No. 6-154097 is, as is well known, a plate-shaped heat shield plate provided between the main body case and the plate.

[0007]

However, the above-mentioned conventional hot plate is hung on the bottom of the main body case even when a hot plate is placed by laying a rug such as newspaper on a table or the like during cooking. Due to the action of the protrusions provided
As described above, the main body case is not abnormally heated and is not melted. However, the above-mentioned protrusion of this conventional example must be specially provided at the bottom of the main body case in order to prevent the ventilation hole from being closed, and the protrusion provided for other purposes must be provided. There was a problem that it was not used for both.

Further, since there is only one heat shield plate, when the hot plate is used for a long time, the heat insulating effect on the bottom plate of the main body case or the mounting surface such as a table is not perfect.

The present invention is intended to solve the above-mentioned problems of the prior art, and to prevent the main body case from being melted and damaged due to the ventilation holes being blocked by the rug laid below the main body case. In addition, a support member vertically provided at the bottom of the main body case that can support an accessory member such as a power cord without providing a special member for preventing the vent hole from being closed, such as the protrusion of the conventional example, can be provided to block the vent hole. I also use it as a preventive,
It is intended to provide a support member that effectively utilizes the support member. Further, it is intended to prevent the ventilation hole from being closed by suspending a protrusion on a downward rib provided on the lower surface of the mouth edge of the ventilation hole formed in the center of the bottom of the main body case. Further, the present invention provides a heat shield plate having a double structure to further improve the heat insulating effect.

A second support member that is arranged closer to the center than the support member and supports the plug of the power cord with a plug is preferable.

Further, in the case of a spatula as an accessory member,
The support member is preferably provided inside the bottom leg of the body case.

A hot plate comprising a plate provided on the main body case heated by an electric heater, a large-diameter vent hole provided at least at the center of the bottom of the main case, and a plurality of legs provided on the outer periphery of the bottom part. In the above, it is also possible to provide a downward rib on the lower surface of the mouth edge of the vent hole and to project a protrusion on the downward rib.

The heat shield plate provided between the plate and the main body case has a double structure of an upper heat shield plate and a lower heat shield plate, and the upper heat shield plate is fixed to a spacer with a screw. While fixing with the stopper, the lower heat shield plate is locked by the locking part of the spacer mounting bracket, and the upper surface of the lower heat shield plate is the same as the screw for the heater stopper and the protrusion protruding from the lower heat shield plate. It is preferable that the structure is pressed and fixed by the section.

[0017]

In the hot plate of the present invention, when not in use, attached members such as a power cord and a spatula are supported by a support member vertically provided on the bottom of the main body case.

When the hot plate is used, a power plug provided at one end of the power cord is connected to an outlet and electricity is applied to heat the plate with a heater to cook the food. At this time, even when a rug is laid under the main body case, the support member of the main body case limits the floating and bending of the rug, so that the vent covers the ventilation hole formed in the bottom of the main body case. And the outside air smoothly flows into the ventilation hole. Therefore, the heated air in the space between the main body case and the heat shield plate is radiated to the upper part of the outer periphery of the space, and the main body case is prevented from abnormal heating and melting damage is prevented.
