Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot air circulation oven that heats food by circulating hot air within a heating chamber.

Conventionally, hot air circulation ovens have been proposed that are equipped with a hot air circulation mechanism in the heating chamber, and a shelf with a trolley loaded with food is brought into the heating chamber to bake many foods at once. There is a considerable temperature difference between the hot air outlet and the hot air suction outlet indoors, and food placed on shelves may be burnt or undercooked depending on the location, causing many heated foods to become burnt or undercooked. There was a problem that the food could not be heated evenly, causing uneven cooking.

This invention was made to solve the above problems, and is a hot air circulation oven that can evenly and uniformly heat a large number of foods placed on a revolving shelf with a trolley carried into a heating chamber using circulating hot air. The purpose is to provide

Embodiments of the present invention will be described below based on the drawings.

Fig. 1 shows a longitudinal cross-sectional view of the hot air circulation type oven, and Fig. 2 shows a cross-sectional view of the same. The rotary shelf 3 is configured to be carried in as is. There is a hot air path 4 on the back wall of the heating chamber 1.
Furthermore, a suction port 5 is formed on the wall of one of the pairs and communicates with the hot air passage 4 and the heating chamber 1 to suck hot air.
is formed on the other wall of the heating chamber 1.
A discharge port 6 is formed to discharge the discharge inside. This discharge port 6 communicates with a hot air generator 7 provided on the side of the oven body, and the hot air generator 7 equipped with a gas burner and a blower generates hot air of about 250°C and sends it into the heating chamber 1. The hot air circulation mechanism is constructed. Reference numeral 8 denotes a drive gear which is attached to the rotating shaft of a gear motor 9 installed at the bottom of the oven main body and projects horizontally downward into the heating chamber 1, and is attached to the rotating shaft 10 for the shelf of the rotating shelf 3 with a trolley, which will be described later. Axially mounted gear 11
It is possible to engage with the As shown in FIG. 3, the rotating shelf 3 with a cart consists of a rotating shelf 3b that is rotatably supported vertically via bearings on a frame 3a to which a cart 12 is attached to the bottom. A plurality of shelf boards or mesh shelves are attached to the shaft 10 at predetermined intervals, and a gear 11 is attached at the same horizontal position as the drive gear 8 in the heating chamber 1 . Therefore, the rotating shelf 3 with a cart moves on the floor and completely enters the heating chamber 1, and the rotating shelf 3b moves along the floor and completely enters the heating chamber 1.
1 and is slowly rotated by a gear motor 9.

Next, the operation of the hot air circulation oven will be explained.
First, food such as fish is placed on the rotating shelf 3 with a trolley, the rotating shelf 3 with a trolley is carried into the heating chamber 1, and the door 2 is closed.
Close the door, start the hot air generator 7, and send hot air to the heating chamber 1.
circulate within. At this time, the hot air is discharged horizontally from one pair of discharge ports 6 in the heating chamber 1, flows horizontally, passes between the rotary shelves 3b, enters the other pair of suction ports 5, and returns to the hot air generator 7. to be heated and circulated again. On the other hand, the rotating shelf 3 with a trolley is connected to the heating chamber 1.
In the state in which the drive gear 8 is brought into the fixed position, the gear 11 of the rotary shelf 3b is engaged with the drive gear 8, and the rotary shelf 3b is slowly rotated by the operation of the gear motor 9. Therefore, the food on the rotating shelf 3 changes its horizontal position from the discharge port 6 side to the suction port 5 side, and is heated evenly and uniformly. Then, the baked food is taken out from the heating chamber 1 together with the cart-equipped revolving shelf 3.

In the above embodiment, gears were used as the rotational drive unit and rotational transmission means for transmitting the rotational driving force of the gear motor 9, but any rotational force transmission means that can be easily engaged and separated can be used as a friction roller. etc. can also be used.

As described above, the hot air circulation type oven according to the present invention includes a rotating shelf with a cart that can be carried into the heating chamber of the oven equipped with a hot air circulation mechanism, and inside the heating chamber there is a rotary shelf that is rotatably driven by a motor. A drive unit is disposed, and the rotating shelf with a trolley is provided with a transmission means that is engaged with the rotational drive unit when it is carried into a fixed position in the heating chamber and transmits the rotational force to the rotating shelf. Therefore, while the oven is operating, the rotating shelf rotates with food placed on it, and works to eliminate the effects of temperature differences in the hot air depending on the situation in the heating chamber, allowing many foods such as fish to be cooked evenly at once. Can be baked and heated.
