Abstract

PURPOSE:To enable the eye-sight observation of foodstuff being cooked and simultaneously to perfectly seal a wave, by arranging such that the opening of heating compartment is perfectly sealed by a door having no window and the heating compartment has its interior portion monitored by an electronic image pick-up device. CONSTITUTION:While a high frequency generator 2 supplies a high frequency power to a heating compartment 3 for cooking a foodstuff therein by a high frequency wave power, an opening defined at the heating compartment 3 for taking in and out the foodstuff therethrough is provided with a door 6 which closely contacts with a portion around the opening for sealing the heating compartment, and thereby preventing the leakage of wave. The foodstuff is taken in and out of the heating compartment through the door 6. A lens section 14 provided along the central axis of small bore 13 communicated with the inside of heating compartment is combined with a photographing section 15. Furthermore, a displaying means 17 functions to receive an electric signal indicative of a field outputted by the image pick-up section 15 and extract on a displaying face 18 the image of field as received by the lens section 14.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-frequency cooker that can monitor food being cooked and has extremely low high-frequency leakage.

Cooking is normally monitored through the window in the door of the heating chamber, and this door is completely sealed in high-frequency cookers.
Furthermore, there is no conventional high-frequency cooking device in which the food being cooked inside is depicted on a display device.

The present invention aims to display cooked food on a monitor and to minimize high frequency leakage.

In the present invention, in order to eliminate high-frequency leakage in the heating chamber, the opening of the heating chamber is completely shielded using a door with no windows, and the inside of the heating chamber is monitored using an electronic imaging device. In particular, the aim is to provide a cooking device that allows the user to see the food being cooked, as well as a cooking device that does not leak radio waves, like a general cooking device.

The drawing is a schematic diagram of a high frequency cooker related to the present invention. In the figure, a high frequency generator 2 is installed in a cabinet 1.
There is a heating chamber 3 coupled to. There is a window 4 in the front of the heating chamber 3 through which food to be cooked can be taken in and taken out, and this window 4 is sealed in the following manner. That is, during high-frequency cooking, a door 6 without an opening that can be brought into close contact with the front surface 6 of the heating chamber in order to prevent high-frequency leakage can be rotated in the direction of arrow 8 by means such as a flavoring device 7 attached to the heating chamber 3. It is configured as follows. Handle 9 at the top of door 6
is a stopper that makes it easier to open and close the door. The direction of rotation of the door 6 is not limited to the vertical direction shown in the drawings, and it is also possible to arbitrarily set it in the horizontal direction. A plate 10 placed in the heating chamber is a tray for placing food 11 to be cooked. A small hole 13 is formed in the side surface 12 of the heating chamber 3.
4 is provided, and a lens portion 14 is mounted on the central axis thereof. This lens section is taken out from the imaging section 16, and the inside of the heating chamber 3 is exposed to the imaging section 16.
It is possible to capture images by Note that the field of view can be arbitrarily adjusted by an adjustment mechanism (not shown) of the lens portion 14. The object is taken out from the imaging unit 15 in the form of an electrical signal,
The signal is applied to the display device 17 via the cable 16. For example, a television receiver and display section is used as the display device 17, and the inside of the heating chamber 3 is depicted on the display surface 18. That is, according to the present invention, the interior is depicted on the display surface 18 even though the door 6- does not have an opening, so in a conventional high-frequency cooker with a door opening,
This makes it possible to completely seal off radio waves even at night, and also to be able to see the food being cooked inside.

For the imaging section 15, an electron tube such as a vidicon can be used, and various solid-state image sensors can also be used.

As explained above, according to the present invention, it is possible to realize a complete radio wave seal in a high-frequency cooking device, and to have the advantage of being able to see the food being cooked.
