Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating cooker that performs cooking using the heat generated by a heater, and in particular, it can be used to cook food by using two types of pots each having different sizes. The purpose is to provide an extremely useful heating cooker that can perform two types of cooking with one model.

Hereinafter, one embodiment of the present invention will be explained with reference to FIGS. 1 to 4. First, in FIG.
2 is an outer frame, and 2 is an inner frame that is connected to the outer frame 1 together with the upper frame 3, and this inner frame 2 has a first heater 4 and a second heater 5 arranged at its inner bottom. There is. still,
Regarding both the first and second heaters 4 and 5, especially in the case of this embodiment, the power consumption of the second heater 5 is set to be smaller than that of the first heater 4, and the resistance is set to be larger. The heater 5 is used in a form embedded in a heating plate 6. Now, 7 is the first pot, which is of a size that is slightly away from the heating plate 6 and far away from the inner frame 2, and is placed on the upper frame 3 by fitting the stepped part 8 into the upper frame 3. It is rotatably attached to a hook 10 of the placed lid 9 and held in each of the above-mentioned separated states, and the lid 9 is also provided with a pressurizer 11, a safety valve 12, and a handle 13. . On the other hand, in FIG. 2, 14 is the first pot 7.
A second pot is provided along with the heating plate 6 and is large enough to be close enough to the inner frame 2, in short, it is larger than the first pot 7. In use, the lid 9 is simply placed on the second pot 14. 15 is a pot detection lever attached to the inner frame 2 as shown in FIG.
It has a detection rod 16 at its tip end that passes through the wall of the inner frame 2, and is urged toward the center of the inner frame 2 as a whole.
In addition, reference numeral 17 denotes a switch disposed outside the inner frame 2 in association with the pot detection lever 15, and is connected to the fixed contact piece 1.
7a and a movable contact piece 17b, this movable contact piece 1
7b is separated from the fixed contact piece 17a by the detection rod 16 pushed out by the second pan 14 mounted in the inner frame 2, and the movable contact piece 17b is in the "open" state. Of the first and second heaters 4 and 5 connected in series to the power source E as shown in FIG. Second heater 5
are connected in parallel. Incidentally, reference numeral 18 in FIG. 3 denotes, for example, three protrusions protruding from the inner surface of the inner frame 2 in order to uniformly hold the second pot 14 mounted inside the inner frame 2.

Next, to describe the operation, first, in the state shown in FIG.
7 also remains in the "closed" state, the second heater 5 in FIG. Cooking by heating by generating heat, especially the lid 9
When used as shown in FIG.
In the state shown in FIG. 2 in which the second pot 14, which is large enough to push out the
is in the "open" state, the short circuit of the second heater 5 is broken, and the second heater 5 generates heat almost without causing the first heater 4, which consumes more power and has a lower resistance, to generate heat. However, it is possible to obtain the function of a so-called slow cooker that slowly heats the second pot 14 little by little with less power consumption than the above-mentioned one, and in general, it is possible to perform two types of cooking with one model, making it very useful. You get it.

Note that the first and second heaters 4 and 5 do not have to have different power consumptions as described above, but may be the same heater. Also, both the first and second pots 7,1
4 may be used in the opposite manner as described above, that is, the first pot 7 is used as a slow cooker and the second pot 14 is used as a pressure cooker. If the switch 17 is changed to a normally open switch 19 as shown in FIG. Alternatively, as shown in FIG. 6, a changeover type switch 20 may be used, and the electric circuit may be configured to switch between the first heater 4 and the second heater 5.

In addition, instead of providing two types of heaters as described above, it is also possible to provide only one type of heater and change the amount of heat generated by the heater by changing the conduction angle of the triax. The present invention is not limited to the above embodiments, and may be modified and implemented as appropriate without departing from the spirit of the invention.

As explained above, the present invention includes two types of pots of different sizes, and a switch that responds to the installation by selecting one of them, and this switch causes the heater to heat the pots to generate heat. The present invention is characterized in that the amount of cooking is different for each pot, and thus provides an extremely useful heating cooker that can perform two types of cooking with one model by properly using the two types of pots. It is possible.
