Water level sensing unit, steam generator having the same, and heating cooking apparatus having the steam generator

Abstract

The water level sensing unit includes a sensing member having a sensor, the sensing member being installed at a side of the steam container, and a pivoting member having an extension adapted to pivotally rotate about a side thereof having a fixed position on the basis of the level of water. The sensor is adapted to sense positional variation of the extension, to thereby sense variation of the level of water in the steam container.

Description

technical field [0001] The present invention relates to a water level sensing unit, a steam generator having the water level sensing unit, and a heating and cooking device having the steam generator, and more particularly, to a device having an improved structure so that even when there is A water level sensing unit capable of reliably sensing changes in water level even when there is a large amount of scale, a steam generator having the water level sensing unit, and a heating cooking device having the steam generator. Background technique [0002] Examples of common heat cooking equipment used to cook food include microwave ovens using high frequencies, gas ovens, and electric ovens (or electric ovens) designed to heat food directly using heaters. Among the above-mentioned heating and cooking devices, the microwave oven has great limitations in the types of food cooked therein, and because it dries the food excessively, the taste of the food cooked by it becomes poor.

Problems solved by technology

[0008] However, the above-mentioned conventional water level sensing unit has the following problem: the float made of styrofoam material eventually absorbs excess water

A soaked float will have difficulty performing its effective up and down movement and may not accurately sense changes in water level

[0009] Moreover, the steam container can also be damaged by the scale caused in it when the steam is generated
