Abstract

PURPOSE:To provide an oven which is capable of cooking a substance to be cooked with a uniform heat even in the case of a large capacity chamber formed through the medium of a partition, by a method wherein a hot air outlet and an air inlet are formed in an upper part and a lower part, being positioned facing and opposite to each other, an auxiliary air inlet is formed between the hot air outlet and the air inlet, and the auxiliary air inlet is formed in a size smaller than that of the main air inlet. CONSTITUTION:A hot air outlet 3 is formed in an upper part of a rear wall, a main air inlet 4 in the lower part of the rear wall, and an auxiliary air inlet 5, being smaller than the main air inlet 4, is provided between the hot air outlet 3 and the main air inlet 4. A partition 6, having the same area as a horizontal area of an oven chamber 1, is placed on tray support parts 2 in the vicinity of the auxiliary air inlet 5, and this method forms an independent chamber having a small capacity above the partition 6. Thus, most of blast from the air outlet 3 is circulated by convection in the direction of the main air inlet 4 from the air outlet, and a part of it is circulated by convection in the direction of the auxiliary air inlet 5 from the air outlet, which results in performing an excellent cooking in a large capacity chamber.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opener that allows the volume of an oven compartment to be varied.

Generally, in this type of open oven, as shown in FIG. By arranging the partition plates 16 of the same size, a small-capacity independent chamber is formed below the partition plate 16, and the partition plate 1
By removing 6, a large volume similar to the conventional one can be formed and the volume can be varied. In addition, 17 in the figure is a minus child, and 18 is a saucer.

However, since this open intake port 14 is located in the middle, especially when removing the partition plate 16 to create a large volume,
If the hot air from the hot air outlet 15 flows toward the upper part of the oven compartment 13, there is a problem in that the food set in the upper part of the oven compartment 13 cannot be cooked properly.

Taking the above points into consideration, the present invention provides a discharge port and an intake port facing each other in the upper part and the lower part, and further provides a sub-intake port between the hot air discharge port and the intake port, so that the sub-intake The opening is made smaller than the main intake port to provide an opening that allows food to be cooked evenly even when a large volume is formed through a partition plate.

One embodiment will be described below with reference to FIGS. 1 to 5.

In the figure, reference numeral 1 denotes an oven cabinet, which has a plurality of tray holders 2 protruding from the side wall, a hot air outlet 3 at the upper part of the rear wall, and a main intake opening 4 at the lower part of the rear wall. A sub intake port 6 smaller than the main intake port 4 is provided between the main intake ports 40. Reference numeral 6 denotes a partition plate having the same size as the horizontal area inside the oven chamber 1. By placing this partition plate 6 on the tray holder 2 adjacent to the sub-intake port 6, a small independent volume can be created above the partition plate 6. This is done to form a chamber. Reference numeral 7 denotes a saucer to be placed on the tray holder 2, and the saucer 7 is made with the front and middle portions slightly smaller than the horizontal area inside the oven chamber 1.
A gap T is formed at the front end and the rear end. 8 is a gas burner, and 9 is a fan, which sucks hot air from the gas burner 8 and the like, and discharges the hot air into the open storage 1 through the hot air discharge port 3. 1o is an exhaust port, 11 is a door, and 12 is an intake hole.

When considering the above configuration and performing large-capacity cooking, please refer to Figure 1~
As shown in FIG. 3, food is placed on each tray 7 and placed on the tray tray 2 of each stage without the partition plate 6 provided. Then, most of the hot air from the hot air outlet 3 flows into the main intake port 4, as shown by the arrows in FIGS. can be cooked well.

Next, when performing small-volume cooking, the partition plate 6 is placed on the dish holder 2 adjacent to the sub-intake port 5, as shown in FIG. Then, the hot air from the hot air discharge port 3 is convected as shown by the arrow in FIG. 4, allowing for good cooking in a small volume.

Although the above embodiments have been explained using a forced convection oven as an example, the present invention is not limited to this, and the effects of the present invention can also be achieved with a natural convection oven as shown in FIG.

As described above, according to the present invention, even when forming a large volume,
Various effects can be obtained, such as uniform heating of the entire oven interior, improved open cooking, and the ease of converting between large and small volumes.
