Embodiment Construction

[0055]Next, a first embodiment of the present invention will be described with reference to FIGS. 1 to 6 . Fig. 2 is a perspective view of an electric stove as a heat processor. In FIG. 2 , the main body of the electronic furnace 1 is provided with a heating chamber 3 , which is closed by a door 2 , and a turntable 4 is arranged on the bottom surface of the heating chamber 3 . An operation panel 5 is provided on the front of the electronic furnace main body 1 . The operation panel 5 is provided with an operation unit 6 composed of a plurality of keys, and a display 7 is also provided. Operation part 6 is made up of thawing key 6a, intensity setting key 6b, start key 6c and meat, fishes switch designation key 6d, as the intensity setting key 6b of heating degree specifying device switch ground setting " strong ", " standard. ", "weak" three kinds of heating degree, meat, fish switch designation key 6d is the determiner that is used for discriminating the kind of frozen thing....

Abstract

The invention aims at reducing the uneven heating when performing thawing to the frozen food. A controlling circuit 29 is provided with a plurality of on-off periodic modes to a magnetron 27, when the weight of the frozen food is below the predetermined weight, a short on-off periodic mode is selected, and the magnetron 27 is controlled through the selected on-off periodic mode.

Description

technical field [0001] The invention relates to an electronic furnace with an improved control method for a magnetron. Background technique [0002] Examples of the electric oven include those having a function of defrosting frozen objects. This electronic furnace is equipped with a magnetron, and by turning on and off the magnetron with a single-mode on-off cycle, the heating and thawing of frozen objects can be realized. [0003] This electric oven changes the heating time according to the weight, type and degree of heating of the frozen object. [0004] Generally, it is always desired to uniformly heat the frozen object. However, in the above-mentioned prior electric oven, due to various reasons, a part of the frozen object is often overheated than other parts, thereby causing uneven heating. [0005] In addition, U.S. Patent No. 4,450,366A discloses a method and device for thawing by high-frequency heating, in which the heating process is divided into intermittent stag...
