Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooking device such as a rice cooker.

Conventional technology For example, in the case of a conventional heating cooker that is capable of not only cooking rice but also stewing, the heater cannot be energized unless the heat-sensitive device is activated to enable pot temperature detection (ON position). I couldn't do it. and,
When cooking rice, the heat-sensitive device turns off when it detects that the water in the pot is running out and the temperature of the pot rises rapidly.
The heater is displaced to the desired position, and in conjunction with this, the power supply to the heater is stopped. On the other hand, in the case of simmering cooking, since the water in the pot never runs out, it is not possible to automatically turn off the power to the heater using the heat-sensitive reactor, and the heat-sensitive reactor must be manually moved to the OFF position. .

Conventionally, the operating means for this heat-sensitive device has been provided with a first operating section for operating it to the ON position and a second operating section for operating it to the OFF position, and the operating direction of each is Inevitably, the opposite was true. Additionally, some devices are equipped with a locking mechanism to match the operating directions of the first and second operating sections.

Problems to be Solved by the Invention However, in the former case, since the operating directions of the first and second operating sections are reversed, it is difficult to operate and sometimes erroneous operations occur. In addition, the latter type of locking mechanism has problems in that the mechanism is complicated, increases cost, and requires a large amount of operating force.

The present invention solves these conventional problems and provides a rational operating mechanism for a heating cooker.

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention has the following features:
A heater that heats a pot, a heat sensitive reactor that responds to the temperature of the pot, a main swing lever that has one end linked to the heat sensitive reactor, a first operating section and a second operating section, One of the first operating part and the second operating part is linked directly to the other end of the main swing lever, and the other is linked indirectly to the other end of the main swing lever via a sub-swing lever, so that the first operating part and the second operating part are connected to the other end of the main swing lever. By operating the main swing lever in the same direction, the main swing lever swings in the opposite direction.

Function In the present invention, for example, if the first operating section is directly linked to the main swing lever, operating the first operating section moves the thermal reactor to the ON position and turns the heater on. Start and continue energizing. Moreover, if the heater energization is to be interrupted during the process, the second operation section is operated. At this time, the force of the second operating part is applied to the OFF part in the opposite direction to the ON part via the auxiliary swing lever.
Move the main swing lever in the direction of the part. Therefore, the first and second operating portions can be operated in one direction, and the mechanism requires only the addition of an auxiliary swing lever.

Example Examples thereof will be described below with reference to the accompanying drawings.

The figure shows a rice cooker that can also be used for stewing, and the main body 2 has an upper opening that can be opened and closed by a lid 1.
Inside, a pot 4 fitted inside the protective frame 3, a heater 5 in contact with the bottom surface of the pot 4, and a heat-retaining heater 6 wrapped above the outer periphery of the protective frame 3 are installed. Reference numeral 7 denotes a well-known heat-sensitive reactor consisting of a ferrite for detecting the temperature of the pan 4 and a magnet corresponding to the ferrite, and the magnet is moved up and down by a main swing lever 8. More specifically, this main swing lever 8 is pivotally mounted on the base plate 9 through a support shaft 10, and the overall length is
It is shaped like a letter. The reason for the L-shape is that the magnet of the heat-sensitive reactor 7 is set vertically, and the operating direction is set horizontally.

The magnet is linked to the tip of the main swing lever 8. 11 is a pin provided at the base end of the main swing lever 8, and 12 and 13 are first and second operation parts. The first and second operation parts have first and second buttons 14 and 15 having transparent parts facing the side surface of the main body 2,
It consists of first and second button levers 16 and 17 that are attached to the first and second buttons 14 and 15 and are slidable on the board 9.

A projection 18 protruding from a portion of the second button lever 17 corresponds to one side of the pin 11. 1
Reference numeral 9 is located between the first button lever 16 and the pin 11, and the intermediate part is a sub-swing lever pivotally connected to the base plate 9 via a shaft 20, one end of which engages with the notch 21 of the first button lever 16. A recess 22 into which the pin 11 fits is formed at the other end.

23 is caused by the oscillating movement of the main oscillating lever 8.
It shows the micro switch that is turned on and off.
The wires are connected as shown in the circuit diagram. 24 and 25 are rice cooking lamps and warming lamps, one of which is rice cooking lamp 2.
4 is the first button 14, and the other heat lamp 25 is the second button 14.
They are incorporated into the buttons 15, respectively.

In the above configuration, the operation in the case of rice cooking will be described first. Now, when the first button 14 is pressed, the force is transferred to the sub-swing lever 19 via the first button lever 16.
As a result, the secondary swing lever 19 swings counterclockwise in FIG. 1, and the main swing lever 8 swings counterclockwise. As a result, the tip of the main swing lever 8 rises, displacing the heat sensitive reactor 7 to the ON position, and at the same time, the micro switch 23 is turned ON and only the heater 5 is energized.

When the rice cooking is completed, the heat sensitive device 7 is lowered to the OFF position, so the main swing lever 8 and the sub swing lever 1 are turned off.
9. The first button lever 16 and the first button 14 also return to their original positions, and the micro switch 23 is turned off, forming a series circuit of the heaters 5 and 6, and entering a heat-retaining operation.

Next, for stew cooking, press button 1 as above.
Press 4 to move the heat sensitive device 7 to the ON position,
The heater 5 is energized. However, during simmering cooking, the water in the pot 4 does not run out, so the heat sensitive reactor 7 does not return to the OFF position. However, once the simmering is finished, press the second button 15 and release the second button lever 1.
7 to forcibly move the main swing lever 8 counterclockwise (first
(Fig.) to return the heat sensitive reactor 7 to the OFF position.

Effects of the Invention As described above, according to the present invention, heater energization,
Since the operating direction of the first and second operating sections for stopping is the same, it is very easy to use and erroneous operations can be prevented as much as possible. The configuration for this purpose requires only the addition of an auxiliary rocking lever, and the structure is simple and inexpensive, and the operation itself is smooth.
