BEST MODE FOR CARRYING OUT THE INVENTION
According to the first aspect of the present invention, the second heat shield / reflector on which the heater is mounted is provided with a space above the heat shield, so that the second heat shield / reflector and the heat shield are connected to each other. An air-cooled space is formed between them. A cooling air supply device for the air cooling space is provided. The frame is a plastic product, the heat shield and the second heat shield / reflector are metal plate pressed products, and the heater is a sheath heater.
According to a second aspect of the present invention, in addition to the first aspect, a timer mechanism is interposed between the cooling air supply device (blowing fan) and the controller power plug.
[0007]
【Example】
Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.
[0008]
FIG. 1 is an exploded view showing a main body 1 of a hot plate according to an embodiment of the present invention, in which a heat shield plate 3 of a metal plate pressed product of an iron plate and an aluminum plate and a sheath heater are provided inside an outer frame 2 of a plastic product. The provision of the heater 5 is the same as that of the conventional hot plate body, but a second heat shield / reflector 4 is interposed between the heat shield 3 and the heater 5.
[0009]
In the embodiment, the second heat shield plate / reflection plate 4 has a structure that forms a peripheral wall 4a to increase strength and also has a function as a water receiving tray. An opening window 6 is formed on the bottom surface of the outer frame 2.
[0010]
Referring to FIG. 4, an air cooling space H is formed between the second heat shield / reflector 4 and the heat shield 3.
A projection 7 is formed on the peripheral wall 3a of the heat shield plate 3 so that a slight gap G1 exists between the peripheral wall 3a of the heat shield plate 3 and the peripheral wall 4a of the second heat shield / reflection plate 4, thereby providing a cooling space. A passage is formed for the cooling air K1 from above H to above the top surface 2a of the outer frame 2.
The protrusion 7 is formed on the peripheral wall 3a of the heat shield plate 3 so that a slight gap G2 exists between the peripheral wall 3a of the heat shield plate 3 and the bottom wall 2b of the outer frame 2, so that the outer frame 2 Is formed below the bottom wall 2b.
A through hole 9 is formed in the peripheral wall 3a of the heat shield plate 3 to communicate the cooling space H and the gap G2.
[0011]
In the embodiment, a cooling air supply device 20 including a blower fan 21 and a motor 22 is provided in the heat shield plate 3 adjacent to the peripheral wall 3a of the heat shield plate 3 as air cooling air supply means.
A through hole 26 is formed in the peripheral wall 3a of the heat shield plate 3 and a through hole 25 is formed in the peripheral wall of the outer frame 2 so that outside air can be taken into the blower fan 21.
The air blown by the blower fan 21 is discharged to the outside air from above the top surface 2a of the outer frame 2 by the flow of the cooling air K1 through the cooling space H and the gap G1. Further, the air is discharged to the outside air from below the bottom wall 2b of the outer frame 2 through the cooling space H and the gap G2.
[0012]
A timer mechanism 24 is provided, and the motor 22 is connected to the power supply side of the power plug 23 for the heater 5 via the timer mechanism 24 to control the motor 5 to continue blowing even when the heater 5 is not energized. In addition, a power storage mechanism is provided in place of the timer mechanism 24, and the heater 5 is connected in parallel to the power plug 23, and when the heater 5 is not energized, the power is supplied to the motor 22 for a certain time by the power storage mechanism to continue the air blowing. It may be configured in such a manner.
[0013]
In cooking using the hot plate of the present invention, the cooking plate A is heated by the heater 5 and the bottom surface 2b of the outer frame and the tabletop below the bottom surface of the outer frame are heated by the heat shielding effect of the second heat shield plate / reflector plate 4. And the second heat shield / reflection plate 4 also functions as a reflection plate, thereby effectively heating the cooking plate A and maintaining the cooking plate A at a high temperature.
[0014]
In conventional grilled meat dishes using a hot plate, it is common to add water to a water tray to heat the tabletop and suppress the rise in temperature on the tabletop and floor. However, there is a problem that the food is not delicious due to moisture, and the reflection efficiency is impaired so that the food cannot be sufficiently burned. However, due to the reflection effect of the second heat shield plate / reflector plate 4 and the above-described air cooling effect, Can be cooked without water. In addition, although it is possible to add water to foods with a large amount of fats and oils as needed, for most foods, water is not added to the second heat shield plate / reflection plate 4, The cooking plate is maintained at a high temperature by using the function as a reflection plate.
[0015]
【The invention's effect】
Since the present invention supplies cooling air to the cooling space formed between the heat shield plate and the second heat shield / reflector plate, the present invention is effective in overheating the tabletop on which the hot plate is placed. Can be prevented. In addition, since water is not poured into the second heat shield plate / reflector plate during general cooking, the cooking plate is maintained at a high temperature by the reflection effect of the second heat shield plate / reflector plate functioning as a reflector plate. It has the effect of baking delicious food at high temperatures.
In the second aspect of the present invention, even when the power supply to the heater is turned off, the supply of the cooling air is continued, and the overheating of the tabletop due to the residual heat of the hot plate can be prevented.
