摘要： An RF energy radiation device includes a cavity in which a heating target object is to be placed, an RF signal generation unit, an RF amplifier, a radiation element, a temperature sensor, and a controller. The RF signal generation unit oscillates an RF signal. The RF amplifier amplifies the RF signal and provides RF energy. The radiation element radiates the RF energy into the cavity. The temperature sensor is disposed in the vicinity of the RF amplifier. The controller controls the RF amplifier so that the RF amplifier adjusts the RF energy output in accordance with the temperature detected by the temperature sensor and a plurality of threshold levels. This aspect can improve the reliability of the device.

摘要： A microwave heating device includes the following components: a heating chamber for accommodating a heating target object, a microwave generator that generates a microwave, and a coaxial connector. The coaxial connector includes a center conductor, an insulator, and an external conductor. The center conductor is connected to the output terminal of the microwave generator. The coaxial connector includes an air gap between the center conductor and the insulator. This aspect can reduce the occurrence of cracking of the soldered joint between the microwave generator and the coaxial connector.

摘要： A high-frequency heating apparatus includes: a heating chamber for accommodating a load; a microwave source; at least one radiator; a temperature detector; and a controller. The microwave source generates a microwave and adjusts the frequency and output of the microwave. The at least one radiator radiates a microwave into the heating chamber. The temperature detector detects the temperature in the heating chamber. The controller causes the microwave source to adjust the output of the microwave based on the temperature profile that defines the temperature change in the load, and the temperature in the heating chamber. According to this aspect, food can be heated in accordance with the temperature profile appropriate for the cooking recipe, thereby ensuring the quality of cooked food.
