Problems solved by technology

Thus, conventional cooking devices cannot deal with underheating by simply reheating or radiative cooling
So cooking ends in failure
[0008] In addition, the conventional cooking device has another problem that, in the case of frozen food or refrigerated food, this device cannot use a heating pattern with high heating efficiency according to the kind of the product and its temperature condition. Heats items on demand, resulting in longer heating times

[0130] Next, refer to the following Figure 15A , 15Band 16 describe a high-frequency heating device with a steam generating function as a second embodiment of the present invention. Incidentally, in the following description, the same components as those in the first embodiment are denoted by the same reference numerals used in the description of the first embodiment, and thus descriptions of these components are omitted here. In the high-frequency heating device with a steam generating function according to the second embodiment, as Figure 15A As shown, the top surface of the evaporating dish 35 is covered by a cover 41 provided with a small hole 41a formed in a portion thereof. Thus, if Figure 15B As shown, the location from which the steam is output can be limited to a specific portion of the small hole 41a. In addition, the amount of steam supplied can be adjusted according to the opening area of ​​the small hole 41a.

Abstract

The present invention discloses a high-frequency heating apparatus with a steam generating function, which heat-treats a to-be-heated object by supplying at least high-frequency waves or steam to a heating chamber 11 that accommodates the object. This high-frequency heating apparatus has a high frequency wave generating portion 13, a steam generating portion 15 for generating steam in the heating chamber 11, and a circulating fan 17 for agitating air in the heating chamber 11. Moreover, the high-frequency heating apparatus has a chamber air heater 19 for heating air circulating in the heating chamber 11. The steam generating portion 15 generates steam by heating an evaporating dish 35 that has a water storing recess.

Description

[0001] The application date is December 27, 2002, the application number is 02822745.X, the title of the invention is "high-frequency heating device with steam generation function", and the applicant is a branch of the Chinese invention patent application of Matsushita Electric Industrial Co., Ltd. case application. technical field [0002] The present invention relates to a high-frequency heating device with a steam generating function, which is suitable for heat-treating articles by combining high-frequency heating and steam heating. Background technique [0003] Conventional high-frequency heating devices are a microwave oven with a high-frequency generator for heating, and a combined oven in which a convection heater for generating hot air is added to the microwave oven. In addition, a steam boiler for heating items by introducing steam into a heating chamber and a steam convection oven in which a convection heater is added to the steam boiler are used as cooking devices...
