本考案は加熱室内を高温にし加熱調理する手段

からコスト高となる欠点があつた。 When high-frequency heating is performed, most of the high-frequency energy is absorbed by the object to be heated, and the inside of the heating chamber does not become hot. Therefore, the water vapor generated from the object during cooking is cooled on the door and the inside of the heating chamber, and water droplets adhere to it. This may cause the viewing window in the door to fog up, or water may drip from the container. To prevent this, we have installed an air duct to send air into the heating chamber and an exhaust duct to exhaust water vapor from the heating chamber.The air from the blower that cools the high-frequency generator is forced into the heating chamber, and along with the air, water vapor is removed. Means for releasing it to the outside are known. On the other hand, when heating the heater, the air inside the heating chamber is heated to a high temperature for cooking, so the inside of the heating chamber and the inside of the door also become high temperature, so even if water vapor is generated from the heated object, water droplets will not adhere to the inside of the heating chamber or the door. Hateful. Further, when heating the heater, the heating chamber needs to have a sealed structure in order to prevent heat from being released from the heating chamber to the outside and improve thermal efficiency. However, it goes without saying that when the air blower is operated to send air into the heating chamber, even when the air blower is stopped, air flows outside the heating chamber through natural convection through the air duct and exhaust duct during heating by the heater. Since heat is released, there is a drawback that thermal efficiency is significantly reduced. In addition, as a means to solve the above-mentioned drawbacks, there is a method of arranging an air passage opening/closing device in the air blowing passage or exhaust passage to close the air passage when the heater is operating and prevent heat from being released from the heating chamber, but this method is complicated in structure. Therefore, it had the disadvantage of high cost.
本考案は上記欠点を改善するもので以下図面に
より説明する。 The present invention is intended to improve the above-mentioned drawbacks and will be explained below with reference to the drawings.

It is a heater that increases the temperature of the 5 is a door that prevents the high frequency energy supplied into the heating chamber 3 and the thermal energy generated by the heater 4 from being released to the outside;
Peep window 6 made of heat-resistant glass, perforated metal plate, etc.
is provided. A blower 7 cools the magnetron, and operates only when the magnetron 1 is operating. 8 The air from this blower enters the heating room 3
An air passage 9 introduces air into the heating chamber, and numeral 9 represents an exhaust passage that discharges water vapor and the like generated from the heated object placed inside the heating chamber to the outside.

とはない。 Next, the operation of the high frequency heating device of the present invention will be explained. When only the magnetron 1 is oscillated, the food or other object to be heated stored in the heating chamber 3 is heated and cooked, and the steam generated at that time is sent to the air passage 8, the louver opening 10b, and the air vent 3 by the air blower 7.
Air 1 forcibly sent into the heating chamber 3 via a
1 and is released to the outside. Therefore, water droplets do not adhere to the inner surface of the heating chamber 3 or the viewing window 6 of the door 5.

どの水滴は付着しない。 On the other hand, when only the heater 4 is operated, not only the object to be heated in the heating chamber 3 but also the air is heated by the thermal energy. In this case, the blower 7 is stopped and the air 11 does not flow in. In addition, even if the high temperature air 12 in the heating chamber 3 becomes a natural convection and partially passes through the ventilation holes 3a and exhaust holes 3b and flows into the ventilation passage 8 and the exhaust passage 9, the direction in which the louvers are cut and raised is toward the exterior of the aircraft. Since the direction is downward and heat moves upward, natural convection causes the louver opening 10b to
There is almost no hot air passing through and being released. In addition, since the inside of the heating chamber 3 and the inner surface of the door 5 reach high temperatures, even if no air is blown into the heating chamber 3, water droplets adhere to the inside of the heating chamber 3 and the viewing window 6 of the door 5 to the extent that it becomes a practical problem. do not.

An object of the present invention is to provide a high-frequency heating device with a heater that has excellent thermal efficiency and is inexpensive.
