Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker for heating and cooking with both a high frequency wave and a heater in the same heating chamber, and more particularly to a method for rapidly cooling the inside of the heating chamber after cooking with the heater.

[0002]

2. Description of the Related Art In a conventional cooking device such as a high-frequency heating device equipped with a heater, the inside of the heating chamber becomes hot after cooking in a mode in which the heater operates, but it is naturally cooled to lower it to a temperature near room temperature. Had to wait until
For similar models for commercial use, the heating chamber is always preheated to a certain temperature in order to shorten the cooking time in the cooking mode in which the heater operates. In order to do so, I had to wait for natural cooling.

[0003]

However, as described above, when it becomes necessary to thaw frozen food by high frequency after cooking with the heater operation or during preheating, if the thaw is started while the temperature inside the refrigerator is still hot. Since the outer surface and the inner surface of the food cannot be thawed uniformly, the food cannot be thawed until the temperature inside the refrigerator drops, which is very inconvenient especially when it is necessary to thaw quickly for commercial use.

[0004]

In order to solve the above problems, a heating cooker according to the present invention comprises a heating chamber in a main body, a door for opening and closing an entrance of the heating chamber, and a high frequency wave in the heating chamber. , A cooling fan for cooling the high frequency oscillator, a hot air chamber for housing a hot air circulating fan and a heater for supplying hot air to the heating chamber, and a control for controlling the operation of the electric components. Equipped with a device,
The control device controls both the cooling fan and the hot air circulation fan, or one of them so that the door can be opened independently of the operation of other components. did.

[0005]

In the heating cooker according to the present invention, the hot air circulation fan or the cooling fan is operated independently of the operation of other parts with the door opened when the temperature inside the chamber is high, so that the wall of the heating chamber and By blowing air into the heating chamber, the heating chamber can be rapidly cooled. Therefore, if you want to perform thawing with high frequency when the temperature inside the chamber is high, by performing the above operation, you can wait a very short time. It becomes possible to defrost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, a heating chamber 2 is provided in a main body 1, and an openable / closable door 4 is provided at an opening 3 of the heating chamber for loading and unloading food. The high frequency oscillated by the high frequency oscillator 15 is guided by the waveguide 5, and is radiated into the heating chamber 2 by the rotating antenna 6 which is rotationally driven by the antenna motor 19. Reference numeral 16 denotes a cooling fan for cooling the high frequency oscillator and other electric parts. After cooling the high frequency oscillator with cooling air,
It is guided by an air guide (not shown) and flows into the heating chamber from the opening 20 on the side surface of the heating chamber. 7 is a mounting table on which the food to be heated is placed, and since it is made of a heat-resistant low dielectric constant material such as crystallized glass, the high frequency wave radiated by the rotating antenna 6 passes through the food placing table 7, It is absorbed by the food to be heated. Reference numeral 8 denotes a hot air circulating fan for supplying hot air, which is driven by a motor 13 to rotate hot air in a hot air chamber 10 heated by an electric heater 9 into a heating chamber from an outlet 12 provided on a rear wall 11 of the heating chamber. Supply. Since the outlet 12 is provided in the peripheral portion of the rear wall of the heating chamber, the blown air flows along the upper, lower, left and right wall surfaces of the heating chamber. Reference numeral 14 is an intake port for returning the air from the heating chamber 2 into the hot air chamber 10, and is provided at a substantially central portion of the heating chamber rear wall 11.

Reference numeral 17 denotes a control unit for controlling the operation of all electric parts, and a COOL key 18 is provided.

FIG. 3 is a chart showing the operating state of each part, showing the state of the cooking mode in which both high frequency and hot air are operating between A and B, and cooling the hot heating chamber between B and C. Shows the state of the cooling mode of.

During the cooking mode shown from A to B, all the components such as the high frequency oscillator, the antenna motor, the cooling fan, the hot air circulating fan, and the heater are operating, but the door is opened after cooking and the control unit is provided. COOL key 18
By operating, the cooling mode is changed from B to C, and only the hot air circulation fan operates during this period. Since the hot air circulation fan operates with the heater off and the door open, it sucks cold air from the outside,
Since it flows along the wall of the heating chamber, the entire heating chamber can be cooled rapidly. It is also possible to operate only the cooling fan between B and C, or to operate both the hot air circulation fan and the cooling fan simultaneously depending on the case. When the temperature of the heating chamber falls to a predetermined temperature, it is detected by a temperature detecting means (not shown) such as a thermistor, and the operation of the fan automatically stops.

[0010]

As described above, in the heating cooker of the present invention, the following effects can be obtained.

(1) When it is desired to thaw frozen food by high frequency in a state where the temperature of the heating chamber is high, the hot air circulation fan and the cooling fan are operated independently from the operation of other parts, so that the heating chamber storage The inside can be cooled in a short time.

(2) It is possible to cool the inside of the heating chamber by directly using the parts provided for heating and cooking without adding a special part or mechanism for cooling, so that the structure is simple and inexpensive. It can provide various cooling functions.

(3) By providing the operation section with a dedicated key for operating the heating chamber, the heating chamber can be easily cooled according to the needs of the user.

(4) Since the hot air circulation fan and the cooling fan can be operated with the door of the heating chamber open, cold air outside the heating chamber can be sucked in, and hot air can be discharged to the outside. The heating chamber can be cooled.

(5) Since the outlet of the hot air circulating fan is provided in the peripheral portion of the wall of the heating chamber, the blown air flows along the upper, lower, left and right wall surfaces of the heating chamber, and the heating chamber is shortened in a shorter time. Can be cooled.
