Abstract

PURPOSE:To enable heating of a oxidation catalyst without using a specific heat generating body by a method wherein oxidation catalyst is arranged in the vicinity of a heating means for a discharge passage. CONSTITUTION:The interior of a heating chamber 2 is heated by means of heaters 3 and 4, and a substance to be cooked is cooked. In this case, since a shutter 11 is released, exhaust gas in the heating chamber 2 is discharged to the outside of a body 1 through natural discharge. However, soot of the substance to be cooked during discharge is decomposed by means of a oxidation catalyst 10 heated by the upper heater 3. As a result, soot of the substance to be cooked is not discharged to the outside of the body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a heating cooking device that uses an oxidation catalyst to decompose oil smoke, bad odor, etc. discharged from a heating chamber.

(B) Prior Art This type of heating and conditioning apparatus such as a microwave oven emits oil smoke, unburned hydrocarbons, malodorous substances, etc. during cooking, staining the air in the room. Therefore, in order to decompose oil smoke, unburned hydrocarbons, malodorous substances, etc., an oxidation catalyst is installed in the exhaust passage that exhausts the hot air from the ripening chamber.

This touch hX! Since the catalyst operates at temperatures above 0°C, a heating element is required to heat the catalyst to a temperature below 1:10°C.

(The problem that Akira Hario is trying to solve Book 5 e Akira was created in view of the two drawbacks, and the problem is to provide a heating cooking device that does not require a special heating element to heat the catalyst. do.

(2) Means to solve the problem A catalyst is disposed near the heating means for ripening the heating chamber.

(E) The working catalyst is heated by a heating means that heats the heating chamber, and the catalyst works as follows. Therefore, no special heating means is required to heat the soot.

(f) Example An example of the present invention was installed in the microwave oven JJ-J as shown in the figure.
This will be explained in detail below.

] is a heating cooking device main body, which has a heating chamber 2 with an open front, and the inner surface of the heating chamber wall contains a non-metal which has a self-cleaning function, a deodorizing function, etc.

Moreover, the upper surface of the heating chamber 2 is curved and shaped so that the center round part is high and the outer peripheral part is low.

3 is a 7-ton heater placed on the outside of the heating chamber on the top of the heating chamber 2, and 4 is placed on the heating chamber side of the bottom of the heating chamber 2. The upper and lower surfaces of the heating chamber are heated by both heaters 3 and 1, and the inside of the heating chamber 2 is heated by the qt heat radiated from the heating chamber Ef.

7 is a hole formed on the outer periphery of the upper surface of the heating chamber 2;
is an exhaust passage f9 placed above the L heater 3 on the heating chamber 2-A side, through which the hot air in the ripening chamber 2 is exhausted from the air vent 7 to the outside of the main body 1 by the blower fan 9. It is supposed to be done. 10 is an oxidation catalyst such as gold or radium arranged above the upper heater 3 in the exhaust passage 8; l1 is +1 upstream of the blower fan 9 in the exhaust passage 8; Exhaust passage 8
It is designed to control opening and closing. 12 is an outer member covering the upper part of the exhaust passage 8, l3 is ]rj, and f of the lower heater 4.
It is an insulating material that covers both sides.

II is a front body that can open and close the front opening of the heating chamber 2, and has a window l5 made of heat-resistant glass, through which the inside of the heating chamber 2 can be visually observed. ing.

1G is a magnetron that supplies microwaves into the heating chamber 2; 17 is a serving material installed in the heating chamber 2;
This is a saucer that serves as a placing stand, and the placing part (
(not shown) so that it can be freely inserted from the front opening of the heating chamber 2; This is a grill that serves as a place for placing the food to be cooked.

When the preheating mode is selected, the heaters 3 and 4 are energized as shown in FIG. Minimize emissions. Also, the oxidation catalyst 10 is heated by the L heater 3! L.

If you select the grill I1 mode, which cooks foods with little oil smoke, such as gratin, the foods will be cooked in the hu ripening room 2.
When the heater 3 heats the inside of the heating chamber 2 and the heating chamber 2 is closed with the t. The food to be eaten is cooked. At this time, since the shutter II is open, the hot air in the heating chamber 2 is released to the outside of the main body 1 by natural haiku. Since the oxidation catalyst 10 is heated by the upper heater 3, the oxidation catalyst 10 A from the cooking chamber 2 decomposes the smoke, etc. from the food to be cooked by the oxidation catalyst. There will be no oil or smoke from the food being cooked outside the body.

When selecting Group 1 mode for cooking foods such as fish and meat that have a lot of oily smoke, the foods to be cooked are stored in the heating chamber 2, and the heating chamber 2 is closed with a 17-liter body. Then, the inside of the heating chamber 2 is heated by the heaters 3 and 4, and the liquid food is cooked. At this time, the shutter l] is released and the blower fan 9 is operating, so that the hot air in the heating chamber 2 is discharged to the outside of the main body l by the blower fan 9. The exhaust gas from the heating chamber 2 is heated by the oxidation catalyst IQ and the heater 3! Therefore, as mentioned above, the oxidation catalyst decomposes the oil smoke etc. from the food being cooked. There is oil smoke etc. from Kicho buried on the outside of main body 1.
I won't be bothered.

When the microwave cooking mode is selected, the shutter 11 is opened, the blower fan 9 is activated, and the magnetron 16 is activated to cook the food in the IJIJ heat chamber. In this case, G. Oxidation catalyst because heater 3 is not energized! +) or tJn It is not heated, it is muddy, and the oxidation catalyst 10 does not have the decomposition effect of oil smoke etc., but since there is little generation of oil smoke etc. in microwave cooking, there is little need for the decomposition effect of the oxidation catalyst 10. It is something.

In addition, in the T-length embodiment, the Ni-heater 3, which serves as a heating means, is disposed above the heating chamber 2J, but it is disposed inside the heating chamber 2,
The oxidation catalyst 10 is arranged above the heating chamber 21 surface to +JIl.
The oxidation catalyst 10 may be heated through the upper surface of the heating chamber.

(g) Effect of the invention 11 According to the author, the oxidation catalyst can be heated by a heating means that heats the heating chamber, and a special heating means for heating the oxidation catalyst is not required. It has the following effects:
