Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooking device such as a hot plate used in general households.

Structure of conventional example and its problems As shown in FIGS. 1 and 2, this type of conventional cooking device has a heating element 2 embedded in the bottom of the cooking device main body 1, and A case 3 is fixed to a protrusion 4 provided on the cooking device main body 1 with fixing screws 5 so as to cover the bottom and circumferential surfaces. Reference numeral 6 denotes a handle/leg body, and this handle/leg body 6 is attached to the case 3 with mounting screws 7. The case 3 is press-molded from an iron plate or the like, and the surface is painted with heat-resistant paint. is common. 8 is an automatic temperature controller inserted into the plug cover 9, 10
is a lid placed on the cooking device main body 1, and this lid 10 is provided with a knob 11 in the center.

However, in the conventional configuration described above, since the cooking device main body 1 is heated by the heating element 2, the case 3 becomes high temperature, which causes problems such as burns.
Generally, in this type of cooking device, there are problems such as the handle portion of the handle/leg body 6 gets in the way during practical use, and takes up space when stored.

OBJECTS OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and to provide a cooker that is safe, easy to use, and can be stored more easily.

Structure of the Invention In order to achieve the above object, the cooker of the present invention has the following features:
A dish-shaped cooking device body, which has a heating element on the bottom and an inclined rising wall on the outer periphery, and a flange that hangs down from the upper end of the rising wall; A dish-shaped first guard that covers a space that serves as a cooling air passage and has an air hole formed in its bottom, and a second guard that covers the circumferential side of the first guard with a space therebetween. a synthetic resin guard formed integrally with the second guard, and a space between the circumferential surfaces of the second guard and the first guard, the lower part of which is open to the atmosphere;
The upper part serves as a cooling air passage between the cooker main body and the first guard, and is in communication with the lower part. According to this configuration, since the second guard is thermally shielded by the first guard and communicates with the outside air, the second guard will not be overheated, and as a result,
It can fully fulfill its function as a handle, and since this second guard also serves as a handle,
It is no longer necessary to provide a handle that protrudes outward from the side of the cooker body as in the past, so the handle does not get in the way in practical terms, and it does not take up much space when stored. This allows for improved storage performance.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below based on the accompanying drawings.

In FIGS. 3 and 4, reference numeral 12 denotes a cooking device main body, which is die-cast and formed into a dish shape with an open top surface, and the outer periphery of the cooking surface 13 has an inclined surface. While forming a rising wall 14, this rising wall 14
A flange 15 is formed that hangs down from the upper end of the flange, and a plurality of ribs 16 are formed in the space formed by the rising wall 14 and the flange 15. Further, a heating element 17 is buried in the bottom of the cooking device main body 11, and a heat shield plate 18 is fixed to the cooking device main body 12 with fixing screws 19 so as to cover the heating device 17 portion.

20 is a guard made of synthetic resin, this guard 20
As shown in FIG. 5, it is made of polyester synthetic resin such as polyethylene terephthalate resin and is formed into a substantially dish shape, and includes a first guard 21 that covers the bottom and circumferential sides of the cooking device main body 12, and a A second guard 22 that covers the circumferential side of the guard 21 of
and a first guard 21 and a second guard 21.
The guard 22 is integrally formed with a space 23 in between. Further, a plug receiving frame 24 is integrally formed on the circumferential side of the guard 20, and legs 25 and air holes 26 are integrally formed on the bottom surface, and a mounting hole 27 is provided, and the guard 20 is fixed to the heat shield plate 18 with mounting screws 28. are doing. Furthermore, on the upper edge of the first guard 21,
A protrusion 29 is provided, and this protrusion 29
0 is set so that when it is fixed to the heat shield plate 18, it comes into contact with the ribs 16 formed on the cooking device main body 12. Further, at this time, the height of the projection 29 is set so that a ventilation section 30 is formed between the flange 15 and the second guard 22. In addition, the third
In the figure, 31 is an automatic temperature controller, 32, 33
are the lid and lid knob.

As is clear from the above configuration, the first guard 2
1, the air entering from the air hole 26 provided on the bottom is released to the outside from the ventilation section 30, so that it receives a cooling effect due to convection, and the second guard 22 has a space that communicates with the outside. Since it is provided outside the first guard 21 via 23,
This second guard 22 can also be kept at an extremely low temperature, which not only prevents burns but also
It can also be used as a handle, so
Since there is no need to separately provide a handle that projects outward from the side surface of the cooking device body as in the conventional case, storage efficiency is also improved.

Effects of the Invention As described above, according to the present invention, there is a first guard made of synthetic resin that covers the lower surface and the circumferential side of the cooking device main body, and a second guard that covers the circumferential side of the first guard with a space therebetween. Since the second guard is integrally formed with the first guard, the second guard is thermally shielded by the first guard, and in addition to natural convection in the space, the upper part is connected to the cooker main body and the first guard. The cooling air passage between the guards communicates with the 〓, and the airflow that passes through it promotes the convection itself, allowing a large amount of air to flow, thereby providing sufficient cooling. Therefore, the second guard will not be overheated, and as a result, this second guard can fully fulfill its function as a handle, and
It is possible to improve safety, and there is no need to provide a handle that protrudes outward from the side of the cooker body as in the past, so the handle does not get in the way during practical use, and it is easy to store. This allows for improved storage capacity without taking up much space.
