Abstract

PURPOSE:To eliminate a removal of a turn table when a hot air heating is carried out in a cooking device for performing both a microwave heating and a hot air heating by a method wherein a bottom wall of a heating chamber is formed with a recessed portion and a food mounting rotary turn table is arranged with its upper surface being equal to or lower than an upper surface of the bottom wall. CONSTITUTION:A bottom wall 1b of a heating chamber is formed with a recessed part 10 and a turn table 13 driven by a motor 12 is arranged in the recessed part 10 through a shaft 11. At this time, an upper surface of the turn table 13 is positioned at the same height as that of an upper surface of a bottom wall 1b or lower than that of the upper surface of the turn table 13. With this arrangement, there is no projection into the heating chamber 1 and thus it is not necessary to remove the turn table 13, resulting in that a flow of hot air is made smooth and so any irregular cooking can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Field: 1) Field of the Invention The present invention relates to a steamer capable of performing both microwave heating and hot air heating.

(b) Prior Art A cooking device capable of performing both microwave heating and hot air heating is disclosed in Japanese Patent Publication No. 14060/1983.

Fig. 5 shows a conventional example of such a cooker, in which microwaves are supplied from a magnetron (21J) into the heating chamber (2), and hot air is supplied as shown by the arrow from a hot air supply device txz. During wave heating, a turntable for placing food is removably mounted in a rotary table driven by a motor (2) through a narrow opening, so that the food is heated by microwaves while being rotated.

Also, when heating with hot air, the turntable (26) is removed and the food shelf is removably attached, so that item A is heated with hot air on the food shelf @ magatama.

However, in the above cooker, when heating with hot air, the turntable (to) must be removed each time, which is troublesome, and furthermore, even if the turntable (to) is removed, there is no turntable in the heating chamber CI. The flow of hot air supplied to the narrow heating chamber ω, whose inner and outer shafts protruded, was disturbed, and as a result, a uniform heat distribution within the heating chamber (2u) was not achieved, resulting in uneven baking. .

(c) Problems to be Solved by the Invention The present invention eliminates the trouble of having to remove the turntable during hot air heating, and also eliminates uneven baking during hot air heating.

B) Means for Solving the Problems The cooking appliance of the present invention comprises: a heating chamber; a microwave supply means for supplying microwaves into the heating chamber; a recess formed in the bottom wall of the JJD heating chamber; a turntable for placing food that is disposed in the recess and whose upper surface is substantially equal to or below the upper surface of the bottom wall of the heating chamber and rotates during microwave heating; and a hot air supply means for supplying hot air into the heating chamber. and a food shelf that is removably disposed within the heating chamber during hot air heating.

(E) Function The turntable for placing food is placed in a recess in the bottom wall of the heating chamber, and its top surface is approximately equal to or located below the top surface of the bottom wall of the heating chamber. There are no protruding objects, so there is no need to remove the turntable during hot air heating, and the flow of hot air is not disturbed.
A uniform heat distribution is obtained, and the firing is uneven.

(F) Embodiment FIGS. 1 to 4 show a cooking device according to an embodiment of the present invention. Microwaves are supplied into the heating chamber (1) from a magnetron (2), and hot air is supplied from a hot air supply device (3) as shown by the arrow to circulate the hot air. The above hot air supply device (3)
consists of a hot air supply chamber (4) partitioned behind the heating chamber rear wall (1a), a heater (5) and a fan (6) arranged in the supply chamber, and a fan motor (6) that rotates the fan. 7)
and an intake hole (8) and an exhaust hole (9) formed in the rear wall (1a) of the heating chamber. Further, a recess aυ is formed in the bottom wall (1b) of the heating chamber, and a turntable α for placing food thereon is arranged in the recess, which is driven by a motor α2 via a shaft Qll. At this time, the upper surface of the turntable a3 is located approximately equal to or below the upper surface of the heating chamber bottom wall (1b). In addition, in the heating chamber (1), there is a food shelf n51 having a square shape and having hot air passage holes (141) equally on four sides.
as+ is detachably attached. In this case, the food shelf α51a51 is supported by a shelf support αe formed on the side wall (IC) of the heating chamber.

The upper rear part of the shelf support αe is an inclined surface (16a), while a protrusion αD having an inclined portion (17a) is integrally formed on the lower side of each corner of the food shelf α9α9.

Therefore, during microwave heating, the food shelf (151 (
With I51 removed, the food-mounting rotary turntable (131) is rotated by the motor (12+), so that the food is uniformly heated by microwaves without rotating.

Next, during hot air heating, the food shelf (15109) is mounted in the heating chamber (1) so as to be supported by the shelf supports (161).

At this time, the food shelf 151 (151 is square and can be easily installed without considering the direction), and the food shelf 0a51 has a protrusion (171) with a small inclined part (17a) connected to the shelf holder αG. It slides and moves backward along the inclined surface (16a) of the heating chamber (1) and stably contacts the rear wall (1a) of the heating chamber.In such installation, when hot air is supplied into the heating chamber (1), The hot air circulates in the heating chamber (1) by passing through the hot air passage hole α4 of the food shelf α51 (151),
The food on 1a51 is uniformly heated with hot air. In the case of such hot air heating, a turntable fi for food placement rotation is used.
3 is arranged in the recess αO of the heating chamber bottom wall (1b),
Since its upper surface is approximately equal to or located below the upper surface of the heating chamber bottom wall (1b), it does not protrude into the heating chamber (1), that is, there is no protrusion into the heating chamber (1). Therefore, there is no need to remove the turntable (131), the flow of hot air is not disturbed, and a uniform heat distribution is obtained in the heating chamber (1), resulting in even and more uniform heating. still,
The turntable 0 may be rotating or may be stationary during hot air heating.

(G) Effects of the Invention According to the present invention, there is no need to remove the turntable during hot air heating, and even without removing the turntable, there is no product in the heating chamber, so uniform hot air heating can be performed. I can do it.
