Description

[Detailed description of the invention] This invention relates to an electric cooker that has two functions, an oven function and a plate function, in one device, and has a structure in which the upper body does not close only during plate cooking operation. It is something.

In general, with electric cookers that have both an oven function and a plate function in one device, if the upper body is closed during plate cooking, not only will the original plate cooking not be possible, but the heat from the upper and lower heaters will not work. This is not desirable as oil from the food to be cooked may splash and stain the inside of the upper body, which may further reduce the reflection efficiency of the upper heater. Since the surface directly receives heat from the upper heater, the surface temperature rises above the heat-resistant temperature, which is a drawback.

The present invention has been devised to eliminate the above-mentioned drawbacks and will be explained in detail below with reference to an embodiment shown in the drawings.

1 is a lower main body with an opening on the top surface with support legs 2, 2 attached to the bottom surface, and lower heaters 3, 4 are provided inside the main body, and reflectors 5, 6 are attached to the outer periphery of the lower heaters 3, 4. There is.

Reference numeral 7 is a substantially trapezoidal upper body housing an upper heater 8 therein, and is attached to the lower body 1 so as to be openable and closable by means of hinge mechanisms 9 and 10 attached to the rear thereof.

Reference numeral 11 denotes a changeover switch installed in the lower body 1, and has an operating plate 13 □ that is pressed or released by a protruding pin 12 attached to the upper body 7 side when the upper body 7 is opened or closed.

The switch 11 has a fixed contact 11a for connecting one end of the upper heater 8 and a fixed contact 11b for connecting one end of the lower heaters 3 and 4, as shown in FIG.
and a movable contact piece 14C connected to the power terminal L1 side.
By pressing or releasing the operating plate 13, the movable contact piece 11C is switched to the fixed contact 11a or the fixed contact 11b to perform oven cooking or plate cooking.

The lower heaters 3 and 4 are each connected in parallel to the upper heater 8, and a fixed contact 11b is connected to one end of the lower heater 3, 4.
Diode 1 for output reduction connected to power supply terminal L1
One end of 4 is connected.

In addition, the movable contact piece 11C of the changeover switch 11 is connected to the fixed contact 1
1a, the resistance values of the upper heater 8 and the lower heaters 3 and 4 are set so that their calorific values are the same.

Therefore, when the movable contact piece 11C of the changeover switch 11 is connected to the fixed contact 11a during oven cooking, the upper heater 8 is connected to the power terminal L1. A full-wave current flows from L2, and a half-wave current flows from the diode 14 to the lower heaters 3 and 4.
, 4 have the same calorific value, and when the movable contact piece 11C of the changeover switch 11 is connected to the fixed contact 11b during plate cooking, the power supply terminal is connected directly to the lower heater 3.4, Wave current flows and the amount of heat generated is approximately twice that of the former.

Reference numeral 15 denotes a cooking plate 1 to be detachably placed in the upper opening of the lower main body 1, and a blocking means 16 projecting over the actuating plate 13 of the changeover switch 11 is integrated on the - side edge thereof. Or it is formed separately.

This blocking means 16 has a shape that prevents the upper body 8 from closing when the cooking plate 15 is placed on the upper opening of the lower body 1, and the changeover switch 11 is movable unless the upper body 8 is closed. The contact piece 11C is prevented from switching to the oven cooking side, that is, the fixed contact 11a side.

Here, the operation of the electric cooker of the present invention will be explained.

First, if you want to use it as an oven, place a grill or baking dish on the top opening of the lower body 1 and close the upper body 7, and the protruding pin 12 attached to the side of the upper body 7 will open the switch. By pressing the operating plate 13 of No. 11 downward, the movable contact piece 11C is switched to the fixed contact 11a side.

In this state, the power terminal L1. When a voltage is applied to L2, the upper heater 8 and the lower heaters 3 and 4 are energized, and the food to be cooked is heated uniformly from its upper and lower surfaces.

Next, when you want to perform plate cooking, when the upper main body 7 is opened, the pressing force on the operating plate 13 is released by the protruding pin 12, so the movable contact piece 11C of the changeover switch 11 is on the plate cooking side, that is, the fixed contact. 11b side.

After that, the cooking plate 1 is inserted into the upper opening of the lower main body 1.
5, and connect the power terminal L1. When voltage is applied to L2,
A full-wave current flows through the lower heaters 3 and 4, and the food to be cooked is heated from below with high heat.

At this time, even if the user tries to close the upper body 7 by mistake, the blocking means 16 prevents the closing operation and the changeover switch 11 will not be switched to the oven cooking side.

As described above, in the present invention, the cooking plate is provided with a prevention means that prevents the upper body from closing only when the cooking plate is placed on the upper opening of the lower body. The upper heater is not energized, so there is no possibility that the upper body will get in the way of plate cooking, or that the heat from the upper heater will cause oil from the food to be cooked to scatter and stain the inside of the upper body. It can have many effects, including none at all.

Claims (1)

[Scope of utility model registration request] A lower body equipped with a lower heater and an upper body equipped with an upper heater are pivotally connected to each other so that they can be opened and closed, and when the upper body is closed, both the upper heater and the lower heater are energized to perform oven cooking. In an electric cooker configured so that plate cooking can be performed by energizing only the lower heater when the lower body is opened, there is a method that prevents the upper body from closing only when a cooking plate is placed on the opening on the top surface of the lower body. An electric cooker characterized in that a blocking means is provided on the cooking plate.
