Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a cooking utensil that combines the functions of grilling, roasting, and griddle in one device.
By making the plates such as saucers removable, they have a cooking function particularly suitable for grilling yakiniku or thick steaks, and the structure is compact.

As an electric cooker for yakiniku or steak,
There have been electric hot plates in the past, but no one in which the plates can be separated has been put into practical use. In addition, there was a cooking utensil with a plate set on a hot plate type stove that could be separated, but in this case, it took time to heat the hot plate itself and the start-up characteristics were poor. This 5114 has the disadvantage that it can only be used for conduction heating because it does not generate red heat, and cannot fully demonstrate its grilling and roasting functions.This 5114 forms an air flow passage between the side wall of the plates and the inner wall of the lower body. By doing so, the above-mentioned conventional drawbacks are eliminated, and an embodiment thereof will be described in detail below.

An upper heater 2 is provided inside the upper body 1, an exhaust port 3 with a smoke removal device is provided on the upper surface of the upper heater 2, a glass window 4 is installed in front of the heater 2, and a glass window 4 is installed in front of the heater 2. It is movably locked and rotated around a hinge 6 by an operating handle 7 attached to the front surface of the upper body 1.

The lower heater 8 is provided on the lower heater 8, and the plates 9 are placed close to or in contact with the upper heater 8.
It is supported above. A control box 11 is provided on the front surface of the lower body 6, and a sonicator timer 12 and heater changeover switches 133, .

Next, its operation will be explained.

When the plates 9 are set on the support material 10, the heater changeover switch 13 is switched to the lower heater 8, and the timer 12 is set, the plates 9 are rapidly heated by the lower heater 8 and reach an appropriate temperature. At this time, the heat emitted downward by the lower heater 8 is reflected by the downward casing 14 in the lower body 6 and contributes to heating the plates 9, as well as heating the air in this area and causing heat flow. This heat flow flows upward through the gap G between the side surface of the plates 9 and the side wall surface of the downward housing 14. This heat flow flowing upward contributes to internal heating of the upper body 1. However, combined with the heat radiation from the upper surface of the plates 9, the upper part of the vessel is also preheated in a well-balanced manner.

In this state, as shown in FIG.
When the steak 16 is placed on the top surface and grilled, the plates 9, which are maintained at an appropriate high temperature by continuous high-power energization of the lower heater 8, grill the contact portion of the steak 16 well. At the same time, the heat flow flowing upward warms the parts other than the contact part between the steak 15 and the plates 9, where conductive heat is difficult to transfer, and reaches the coagulation temperature of the meat, thereby serving to prevent the meat juice from flowing out. Thereafter, the steak 15 is turned over and lightly roasted, resulting in a very good steak 15. In this way, in the conventional electric cooker, the heat flow that escapes upwards is absorbed by the upper body 1, which covers the upper surface of the lower body 6 and prevents the heat flow from dissipating. The efficiency is very high because it contributes to the heating of the air. Furthermore, when the plates 9 are heated away from the lower heater 8, the temperature near the lower heater 8 becomes extremely high. It was necessary to cover it or make the body larger.

However, as in this configuration, the sides of the plates 9 and the downward casing 1
If a gap G is provided between the side wall surface of 4 and the side wall surface of 4, the heat flow will flow out through this portion, so that the excessive temperature rise as in the conventional case is suppressed.

Although the plate type 9 has been described in the case of 5 plates in FIG. 4, the same effect can be obtained by providing a gap G using a saucer 16 as shown in FIG.

As described above, the present invention provides for plates to be removably positioned on the lower heater provided in the lower body covered by the upper body, and between the side wall of the plates and the inner wall of the lower body. By forming air flow passages in the grill, even when grilling thick steaks, etc., the temperature of the heated plates and appropriate convection ensure sufficient heating, achieving high heat under optimal conditions. and can be cooked. Furthermore, the upward flow of heat through the air flow passages also suppresses excessive temperature rises, which is of great industrial value.
