Claims

[Scope of utility model registration request]

This device detects the level of the melt produced in the crucible in a patch melting type microwave heating furnace, and is composed of a first temperature sensor and a second temperature sensor. The second temperature sensor is installed to be able to detect a position on the outer wall surface of the crucible corresponding to the upper limit level of the melt surface, and a position on the outer wall surface of the crucible corresponding to a level slightly below the upper limit level of the hot water surface. It has a mechanism for storing the maximum temperature first detected by the sensor, a mechanism for detecting a coincidence between the stored maximum temperature and the temperature detected by the first temperature sensor, and a mechanism for detecting the coincidence of the two hot dusts and the signal to be processed. Microwave heating characterized by comprising a relay part for converting into an operation signal to the material supply device, and controlling the supply of the material to be processed to the crucible based on the temperature of the hot water surface. Furnace hot water level detection device.
