DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a stove used in a kitchen or the like.

[0002]

2. Description of the Related Art Conventional stoves have a stove with a claw on the periphery of an opening formed in a top plate on the upper surface of a stove body, and the flame or hot air from a burner disposed so as to face the opening is used as a stove. It is naturally discharged to the outside of Goku along the bottom of the pot placed on the claw.

[0003]

In the above-mentioned conventional stove, a part of the discharged hot air reaches the handle of the pot and heats it, so that the handle becomes difficult to hold.
In order to solve such a problem, a cylindrical fan that surrounds the flame of the burner is placed on the periphery of the opening of the top plate, and an exhaust fan that forcibly sucks and exhausts hot air from the space surrounded by the heater is provided.
It is conceivable to prevent the fire or hot air from leaking out of Gotoku. However, in this thing, the part of the pot that comes in contact with the flame or hot air is limited to the central part of the pot bottom facing the inner circumference of Gotoku,
There is a problem that the heating efficiency is reduced. In view of the above, an object of the present invention is to provide a stove that prevents the handle from being heated by hot air and can improve the heating efficiency.

[0004]

Means for Solving the Problems In order to solve the above problems,
The stove of the present invention is provided on the top plate of the upper surface of the stove body, with a concave portion into which a pan can be inserted with a gap around the periphery, and around the concave portion, a burner that blows out a flame toward the inside of the concave portion. In addition to the arrangement, there is provided an exhaust passage provided with an exhaust fan, which communicates with the bottom of the recess.

According to the present invention, the flame of the burner spouted inward from the periphery of the recess and the hot air generated by the flame flow from the peripheral surface of the pot inserted into the recess along the bottom surface, and the bottom of the recess is formed. Is forcibly sucked and exhausted from the exhaust passage. Thus, the flame or hot air does not rise above the recessed portion, and the heating of the pan handle is prevented, and the pan is heated not only on the bottom surface but also on the peripheral surface by the flame and hot air. The heating efficiency is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 denotes a stove main body, and a top plate 2 is provided on an upper surface of the stove main body 1. The top plate 2 includes an outer top plate 20 and an inner top plate 21. The inner top plate 21 is formed in a bottomed cylindrical shape, and the inner top plate 21 is formed.
Thereby, the pot P is formed as a recessed portion into which the pot P can be inserted with a gap around the pot P, so that the pot P can be placed on the nail 22 provided on the bottom wall of the inner top plate 21.

In the stove body 1, a burner 3, which is an inner flame type ring burner having a flame hole 3 a on the inner periphery, is provided around the inner top plate 21. A slit-like transparent window 23 which is long in the circumferential direction as shown in FIG. 2 is formed so that the flame hole 3 a of the burner 3 faces the portion, and the flame F of the burner 3 passes through the transparent window 23 into the inner top plate 21. I'm trying to squirt. In addition, if the pot P is eccentrically placed so as to cover a part of the window 23, combustion failure occurs. Therefore, a plurality of projections 24 are formed on the peripheral wall of the inner top plate 21 so that the window 23 is It is prevented from being blocked.

An opening 25 is formed at the center of the bottom wall of the inner top plate 21, and an exhaust passage 4 is provided to connect the opening 25 to an exhaust port 4 a provided at the back of the top plate 2. An exhaust fan 5 is interposed in 4.

A heat shield cylinder 6a extending upward through the opening 25 is inserted into a connection portion of the exhaust passage 4 with the opening 25, and is urged upward by a spring (not shown) to the heat shield cylinder 6a to be attached to the bottom of the pot. The thermal head 6 to be pressed against is housed, and when the bottom of the pot is overheated, this is detected by the thermal head 6 and the burner 3 is extinguished.

Next, the operation of the above embodiment will be described. When the exhaust fan 5 is operated, the secondary air is sucked from above into the gap between the peripheral wall portion of the inner top plate 21 and the peripheral surface of the pot P by the suction force of the exhaust fan 5, and the transparent window 23 is moved. Also, the secondary air is sucked, and the flame F of the burner 3 extends inward through the transparent window 23 and contacts the peripheral surface of the pot P. And flame F
And the hot air generated by the flame flows along the bottom surface from the peripheral surface of the pot P without rising above the inner top plate 21, and the opening 25.
From the exhaust passage 4 forcibly.

Thus, the handle PH of the pot P is not heated by hot air, and the flame F or hot air contacts the pot P not only on the bottom surface but also on the peripheral surface, so that the contact area increases, and Efficiency is improved.
