High frequency heating cooking machine

Abstract

A high frequency heating apparatus (100) having a high frequency generating portion (13) and a steam generating portion (15) for generating steam into a heating chamber (11) for accommodating a thing to be heated and serving to supply at least one of a high frequency and steam into the heating chamber (11), thereby heating the thing to heated, includes a pan (21) which serves to mount the thing to be heated thereon and is provided to be upward removable apart from a bottom face of the heating chamber (11) at a predetermined interval, thereby dividing the space in the heating chamber (11), steam delivery means (29) for supplying the steam generated by the steam generating portion (15) into the upper space positioned above the pan (21), and preheating means (17) for raising the temperature in the heating chamber.

Description

technical field [0001] The present invention relates to a high-frequency heating cooker with steam generating function, in particular to a technique for improving cooking function and heating efficiency. Background technique [0002] Conventionally, there have been various proposals for a high-frequency heating cooker that supplies steam to a heating chamber in which an object is placed to heat the object (for example, see Patent Document 1). This high-frequency heating cooker can perform heating and cooking by appropriately combining high-frequency heating, steam heating by supplying steam, and electric heating in some models. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 8-178298 [0004] However, when the above-mentioned high-frequency heating cooker starts heating, it takes a long time for the steam to enter the heating chamber and reach the predetermined heating temperature, so the heating and cooking time becomes longer, and the use is not nec...

AI Technical Summary

Problems solved by technology

Therefore, after heating and cooking, a large amount of water will be stored in the bottom area of ​​the heating chamber, causing problems such as difficulty in cleaning.

And because the high-temperature steam that enters condenses on the wall of the heating chamber, etc., there is also a problem that the heat of the steam is absorbed by the wall of the heating chamber, and the heating amount of the object to be heated is correspondingly reduced, so that the heating efficiency of the object to be heated is reduced.

[0005] In addition, in recent high-frequency heating cookers, by increasing the volume of the heating chamber, it is possible to heat and cook a large object to be heated, but with the increase in the size of the heating chamber, there is a problem that the entire heating chamber cannot be heated uniformly and rapidly. difficulty

Although the lack of heating capacity can be improved by increasing the number and power of heating devices, it may not be a good solution from the perspective of cost reduction and energy saving for general household high-frequency heating cookers.

[0006] In addition, in the conventional high-frequency heating cooker with a steam generating function, only steam is simply supplied into the heating chamber to heat and cook the object to be heated, and there is no such thing as supplying steam at a required time during grill cooking and adjusting the grill state. function, and can not maximize the performance of steam when heating and cooking, so this type of cooker can only be used in a limited range
