Abstract

PURPOSE:To economize the energy at a small quantity of cooking by a method wherein the movable plate is provided as free in rise and fall at a central part of an oven apparatus which being enabled to divide a chamber into two parts as an upper and lower part by horizontally projecting the movable plate part of which plate supporting part supports an oven plate. CONSTITUTION:The movable plate part 3, the air exhaust hole 4, the intake holes 5, 6 and the exhaust port 7 are arranged on the rear wall 2 of the oven apparatus 1. The movable plate 3 is arranged in such a manner that located at the center of the rear wall, having a length same as the whole width of the rear wall, fixed to the axis 23 as rotatable by being supported its one end and arranged free in rise and fall at the condition enable to be placed parallel with the rear wall 2 and horizontally projected from the rear wall 2. The several parts of the plate holder 21 are arranged on the inside wall 8. When the oven plate 9 is placed on a pair of plate holder, the rear end of the oven plate 9 is attached on the projected movable plate 3 front end of the oven plate 9 is attached on the door 10, then the oven apparatus is divided into the two parts. Thereby, a small quantity of cooking is performed in the upper or lower divided part in the oven apparatus in which the one plate among the oven plates 9 is placed on the plate holder 21 arranged at adequate position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oven having an open tray inside the oven chamber.

Generally, when cooking a small amount of food inside an oven, in order to reduce energy consumption, the inside of the oven is conventionally partitioned off with a special partition plate a as shown in Figure 7, but this Since a dedicated partition plate with a size equal to the cross-sectional area is required, the cost is high, and there are problems such as where to place the partition plate when partitioning is not necessary.

In order to eliminate the above-mentioned drawbacks of the conventional ones, the present invention provides a movable plate, and by rotating the movable plate, the oven pan used for cooking can be used to easily partition the interior of the open oven and reduce the size of the cooking chamber. This is a measure to save energy consumption.

The present invention will be described in detail below with reference to the drawings.

FIGS. 1 to 5 show an embodiment of a forced convection oven, and FIG. 6 shows an embodiment of a natural convection oven.

In the figure, an open storage 1 has a box-like structure, and a rear wall 2 includes a movable plate 3 and an air outlet 4. A 5.6% exhaust air lower air intake port is provided.The air intake port 6 is located above the movable plate 3, and the air intake port 6 is located below the movable plate 3.
is located at the center of the rear wall 2, has a length that spans the length of the rear wall 2, and has one end pivotally attached to a shaft 23 so as to be rotatable as shown in FIGS. 1 to 3. Rotate. That is, it can be freely inverted between a state along the rear wall 2 and a state protruding horizontally from the rear wall 2. On the inside of the side wall 8 of the oven chamber 1, there are several tray holders 21 on which oven plates 9 are placed.
In the horizontally protruding state, the rear part of the oven tray 9 abuts the movable plate 3 and the front part abuts the door 1o, so that the oven tray 9 is divided into an upper chamber 19 and a lower chamber 20 (see Fig. 3). .

There is a door. When the open plate 9 is placed on the other plate holder 21, the rear part of the oven plate 9 comes into contact with the rear wall 2 of the open oven 1, and the front part has a gap between it and the door 10 by the length of the protrusion of the movable plate 3. 18 is now possible. A burner 12 is arranged in a combustion chamber 11 configured at the rear of the oven chamber 1, and a combustion heat intake port 1 is provided on the upper surface of the combustion chamber 11.
3 is provided. Further, in the upper part of the combustion chamber 11, there are fan chambers 1 and 4 that constitute a duct connected to the air outlet 4, an intake port 15 is provided in the front of the fan chamber 14, and a fan 16 is installed in the fan chamber 14. It is arranged.

17 is a temperature detector that detects the temperature inside the open refrigerator.

Next, the operation of opening in the above configuration will be explained.

When cooking a large amount, place the oven tray 9 on the tray holder 21 as shown in FIGS. 1 and 2. The movable plate 3 is the first
Hold it upright using a magnet, etc., as shown in the figure.

When the burner 12 is burned and the fan 16 is rotated, the combustion heat of the burner 12 is drawn to the fan 16, and the combustion heat intake port 13. Intake port 15. It passes through the duct of the fan chamber 14 and is discharged into the oven chamber 1. The air discharged into the oven compartment 1 passes through the gap 18 between the orb tray 9 and the door 1o, is drawn by the fan 16 through the intake ports 15 through the intake ports 5 and 6, passes through the duct again, and enters the re-open oven through the air outlet 4. The air temperature inside the oven chamber 1 is increased.

Excess air is discharged from the air lower, heats the temperature detector 7, and controls the temperature inside the open warehouse 1.

Furthermore, when cooking a small amount, the movable plate 3 is rotated by hand as shown in FIG. Set it in a position where it contacts the movable plate 3. In this state, the four circumferences of the plate 9 are moved by the movable plate 3. It comes into contact with both the side wall 8 and the door 10, and the oven cabinet 1 is divided into an upper chamber 19 and a lower chamber 20. At this time, when the burner 12 is burned and the fan 16 is rotated, the combustion heat discharged from the air outlet 4 into the open storage is sucked in from the air intake port 5, but since there is no air outlet in the lower chamber 2o, It is not sucked in from the wind port 6. Therefore, combustion heat is circulated only in the upper chamber 19. Fig. 6 shows an example of a natural convection open type.
Similar to the forced convection type opening described above, when the oven pan 9 is set in a position where it contacts the movable plate 3, the four circumferences of the open pan 9 are moved by the movable plate 3. The side wall 8° will come into contact with all of the doors 1o, and the open kjId will be divided into an upper chamber 19 and a lower chamber 2o, and the combustion heat from the burner 12 will be released only to the lower chamber 20. .

When the oven chamber 1 is partitioned by the open tray 9 as described above, a small amount of air (for forced convection open, the upper chamber 1
8 only, and only the lower chamber L20 in the natural convection type open oven), it consumes less energy than cooking a small amount in a large open oven. In order to utilize an open plate used for cooking, it is necessary to prepare a separate partition material.In the above embodiment, the explanation is given for a gas open dish, but the same applies to a gas open dish.

Further, in the above embodiment, the movable plate 3 is a manual type, but the movable plate 3 is not limited to this, but may be an automatic type in which the movable plate 3 is operated in conjunction with the sprout tray 9.
