Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking appliance which is constructed with convective heat transfer to obtain high thermal efficiency and whose top plate and other components are easy to clean.

Conventional technology 2: As shown in Fig. 5, this type of cooking device has a Bunsen burner 1 that burns from the center to the periphery, a broth receiver 2, a top plate 3, and a trivet 4 on the top plate. It was structured so that you could put it there.

In such a configuration, the flame is applied directly to the bottom of the cooking container, so the thermal efficiency is high, but it lacks uniform heating properties, and the trivet 4 protrudes above the top plate 3. Therefore, there was a problem that there was a difference in level from the top plate 3, making it difficult to clean the dirty top plate 3, and the appearance was not good. On the other hand, as shown in FIGS. 6 and 7, there is a so-called smooth top type in which the entire top plate 3 is flat and easy to clean. This smooth top type burns with a radiant burner 5, and the exhaust gas passes through an exhaust part 6 and is heated by a fan 7.
The portion of the cooking device main body 3b excluding the top plate 3 is discharged to the outside. On the other hand, a heating surface 8 that burns with the radiation burner 5 and emits radiation faces upward, and above the heating surface 8 a heat transmitting material such as glass is provided with a gap 3 a. It is configured. In addition, a pot A is placed above the top plate 3, and all three containers are discharged through the exhaust section 6 to the outside of the cooking device main body 3b, and the pot A is heated only by heat transfer by radiation from the heating surface 8. Therefore, there was a problem that the thermal efficiency was low at around 30%.

In addition, the smooth top type has the disadvantage that if the top plate 3 is flat and the bottom of the pot A is shaped like an arc, the pot A will start to dance and spin around due to vibrations caused by the boiling of the food during heating. was.

The present invention solves these conventional problems.

To provide a cooking device which has high thermal efficiency, is easy to clean, and has a stable pot.

The trivet exhaust port opening/closing plate forms the same surface as the curved top plate, and when in use, the peripheral exhaust port is left open and the combustion exhaust gas is directed directly to the heated container, preferably on the trivet. Combustion I from central exhaust port and peripheral v1 air port
J1 consists of a centrally opposed burner that forms a flame on the central inner circumferential surface from which gas is discharged.

Effects The present invention has the above-described configuration, and when the cooker is not in use, the trivet and the trivet υ [the vent opening/closing plate and the top plate are made to be on the same surface for easy cleaning. In addition, the trivet has a shape with a hazy center, for example, an inverted conical shape or a truncated conical dome shape, to improve stability when the pot is placed on it, and a burner that mainly uses υ1 air in the center to create convection. It provides a cooker with high thermal efficiency including heat transfer.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 4 of the accompanying drawings. 9 is W, which is made by flattening the flat top plate 10, and 11 is a trivet installed on a part of the top plate 1o, even if it is a pot 12 with a flat or arcuate bottom. In order to ensure stable placement, the trivet 11 has a dish-like shape that gradually slopes downward from the outer periphery to the center and is concave.The trivet 11 has a central exhaust port 13 and a frame around it. It has a peripheral exhaust port 15 formed through 14.

16 is a dish-shaped trivet exhaust opening/closing plate which is disposed below the trivet 11 with a gap 11a in between and closes the peripheral exhaust port 15 when the cooking device main body 9 is not in use; It consists of a higher closing portion 16a which faces each other to have an opening 16c and which fits into the peripheral exhaust port 15 and is flush with the surface of the trivet 11, and a lower portion 16b which is on the lower side of the frame 14.

Reference numeral 17 denotes an inverted U-shaped opening/closing drive body to which the trivet exhaust port opening/closing plate 16 is attached, which moves up and down to move the trivet exhaust port opening/closing plate 16 up and down. 18 is a rack formed at one end of the opening/closing drive body 17;
9 is a motor installed in the cooker body 9.

Pinion 2 meshed with rack 18 by forward and reverse rotation
