Description

[Detailed description of the invention] This invention relates to a heating cooker, and more specifically, the heating temperature and heating time are specified by a combination of the number and position of holes drilled in a cooking card, and the cooking card is inserted into a photoelectric device. The present invention relates to a heating cooker that automatically controls the heating source in terms of time and temperature depending on the situation.

In the above-mentioned heating cooker, there is a heating cooker that has a single light source, which serves both as an illumination light source in the heating chamber that houses the food to be cooked and as a light source for irradiating the light receiving element of the photoelectric device. It is advantageous in various respects.
However, in order to illuminate the inside of the heating chamber and the light receiving element, it is preferable that the lighting be done through the lighting window on the side wall or ceiling wall of the heating chamber, and that the photoelectric device be installed in a position on the front of the cooking appliance where a card can be inserted. There were some inconveniences, such as the location being restricted.

Therefore, this invention provides a cooking device which does not have the above-mentioned drawbacks, and will be described in detail below with reference to the drawings showing embodiments of the cooking device of the invention.

Reference numeral 1 denotes a heating cooker according to the present invention, which has a heating chamber 2 for storing food to be cooked. The food in the heating chamber 2 is heated and cooked by a heat source 3 such as a gas burner.
4 is a lighting window provided on the side wall of the heating chamber 2 and a light source 5
The inside of the refrigerator is illuminated to make it easier to see the condition of the food being cooked.

A photoelectric device 6 is provided with a large number of light receiving elements 7 as shown in FIG. 2, and a card 9 inserted through a card insertion slot 8 is positioned in front of the light receiving elements 7 (on the light source side). The card 9 has holes 10, and the position and number of the holes 10 indicate the heating temperature and heating time.

The light receiving element 7 is illuminated by the light source 5, and the card 9
Due to the different holes 10, the output from the photoelectric device 6 changes to control the operation of the heating source 3, but since this is already a well-known technique, further explanation will be omitted.

Reference numeral 11 denotes a reflecting plate, and the light from the light source 5 is reflected by the reflecting plate 11 and illuminates the light receiving element 7 of the photoelectric device 6 .
In this embodiment, the reflection plate 11
After being reflected by the reflection plate 11, the light beam becomes a substantially parallel light beam Y, as shown in FIG. According to this, since the reflected light beams are substantially parallel, the light receiving element 7 only at the rear of the hole 10 of the card 9 is irradiated, and there is an effect that no malfunction occurs.

Reference numeral 12 denotes a control device for a gas tank, solenoid valve, etc., and the output from the photoelectric device 6 controls the heating source 3 via this control device.

The heating cooker of the present invention is constructed as described above, and when the light source 5 is turned on, the food to be cooked in the heating chamber 2 is illuminated through the lighting window 4 of the heating chamber 2, so that the cooking status can be seen. On the other hand, the light hitting the reflector 11 is reflected by the reflector 11 and reaches the photoelectric device 6, but only the element 7 behind the hole 10 of the cooking card 9 in front of the light receiving element 7 is irradiated. heat source 3 by card 9
Controlled by specified heating temperature and heating time.

As described above, according to the present invention, the light from the light source 5 illuminates the inside of the heating chamber through the lighting window, and
Since the light is reflected by the light and illuminates the light receiving element 7,
Even if the illumination window 4 and the photoelectric device 6 are in an inconvenient positional relationship to serve as a light source, the optical path can be freely bent by the reflector, and a sufficient amount of light from the light source can be given to the photoelectric device. It is possible to eliminate the drawbacks of the conventional method.
