Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooking machine such as a 7-processor for cutting meat, vegetables, and fruits, and relates to an operation control mechanism for a rotating body of the cooking machine driven by a motor.

Generally, in a cooking machine such as a food processor, food is put into a container, and the food is rotated by a motor and cooked by a rotating body provided inside the container. This type of cooker V depends on the type of food to be cooked.
It is necessary to control the speed of the rotating bodies and the operating time. For example, if you look at Japanese Patent Application Laid-Open No. 55-18255J, etc., the SCR or triac I by changing the variable resistor to f.
The speed of the rotating body was controlled by means such as the lj power method and the winding of a 7-ter field winding and +71 conversion, and the
B-! The conventional method is to control the operating time of the rotating body using an electric or mechanical time switch such as that disclosed in Publication No. 14906. When a time switch is used as a means for controlling operating time, it is undeniable that the mechanical time switch has a larger structure, and it is inevitable that there will be spatial constraints when incorporating it into the main body of the machine. The moving parts of a mechanical switch are sensitive to external conditions, and reliability may be compromised.Furthermore, regarding speed control, if a method of switching the number of turns of a seven-tar field winding is attempted, Depending on the number of windings, the motor itself may become large and the cooking device itself may also become large, which may cause a big problem in securing storage space for the cooking device.

In addition, if you try to control the operation of the rotating body in a cooking machine by combining the speed control means and the operating time control means as described above, when you try to drive the rotary body again after the time switch is turned off. , it is necessary to set the time switch again. Regarding the speed control of the rotating body, it is of course necessary to select the optimum rotation speed and operating time depending on the type of food to be cooked, but it is also possible to select various rotation speeds depending on the amount of food to be cooked. It is necessary to set the driving time. However, with conventional cooking machines, it is not possible to convert the rotation speed and operating time according to the quantity limit, and it is extremely inconvenient that large quantities of food need to be cooked in separate batches.

The present invention has been made in view of these conventional drawbacks,
It is an object of the present invention to provide a cooking machine having a control function that allows the rotational speed of a rotating body and the operating time to be varied at any time depending on the amount of food to be cooked.

The structure has a main body with a built-in motor, a container attached to the main body, and a rotating body housed inside the container and driven by the motor. In the cooking machine, the cooking machine is equipped with a control unit that stores data in the order of input and transmits signals to the motor according to the take at any time. Power/Maximum V
It has the function of simply changing (Thl) depending on C.

Therefore, even if the rotational speed and operating time settings of the rotating body change irregularly depending on the amount of food to be cooked, it can be converted to the rotational speed or operating time according to the amount of food with a simple operation.
'L, it is convenient because there is no need to store data in the control unit by performing new key operations.

The following is a detailed explanation of the cooking machine that was completed in January, based on the example of Food Zorro Cellarsy, using the screen as an example.

(1) is the main case! T! It consists of a vertical motor housing (2) and a base (3) that houses power transmission members and various electrical components. A container (4) made of transparent resin is engaged in position a on the T side of the base f3+, and a material input port (61) is superimposed on the L section opening of the garbage container (61). ) are fitted together.

Although not shown in the drawings, a cutting blade is provided inside the container (4) for cutting the food to be cooked that is put into the container (4). This cutting blade is inside the base (3).
It is rotated by a motor (goods) equipped with Ce.

), a reset key (RES) that returns the microcomputer (MC) (described later) to its initial state, a continuous operation key (CON), and a pause key (HAL) that temporarily stops the rotation of the cutting blade during the cooking process. .

In addition, the self-help key switch made by FI1.1 has a 9J sharpening blade suitable for each specific food to be cooked, and the speed IW and operation time call switch has a soft vinyl chloride cover (10) that makes its surface flexible. force that is covered by / < -110)
The end of the key switch is welded or glued to the base (:ll), and the L side has lines printed on each key switch, so you can tell what switch it is by looking at it. In this type of food processor that uses water, etc., the cover (10) can prevent water from entering the key switch group, and is an extremely good waterproof means. is also insulated from the outside, so
The risk of short circuit accidents is also extremely low.

Furthermore, the amount key switch group (Danj is set when the amount of food to be cooked is changed by 1 + amount, and the amount increase key (AD)

) is used when there is little dispersion of the object to be cooked, and by operating this key, at least one of the rotational speed of the cutting blade or the operating time stored in the microcomputer (MC) is applied to the object to be cooked. It is given a certain amount depending on the amount.

Next, the present invention will be explained in detail.

When cooking manually, the cooking process consists of multiple pieces of data using low-speed pulse (LP) and high-speed pulse (H).
Use the speed keys such as P, low speed CLS), medium speed (MS), and high speed (HS) and the operation time key (IO3) (1S) to temporarily store the value in 1<AM on the microcomputer (MC) and start. When the key (5TA) is pressed, the stored data is loaded into the song and the operation of the motor is controlled according to the data.

Also, when performing automatic cooking,

For example, if you press the increase key CAD), the menu key +
Of the data loaded from the ROM by 8+, the operating time is converted into a signal in the form of target * (4 servings) + α, and the operating time of the motor is lengthened for each cooking step. When the reduction key (SU) is pressed, each cooking step is shortened from the ROM using the menu key (Dan). When the forward key () is pressed, the data loaded from the ROM by the menu key (menu key) is involved in the control of the f motor (9). Not only can you increase or decrease the next run time using the quantity keys, but you can also use the motor (6
) can also be increased or decreased. When all the cooking steps are completed, the buzzer (BEP) goes off and the light emitting diode (LED 12) lights up.

As described above, the present invention includes a main body containing a motor, a container attached to the main body, and a rotating body housed in the container and driven by the motor. Store the data in the order of input.1
．． In an example of fc cooking, the control section includes a control section that transmits a signal to the motor according to the mode at any time.
Since it has the function of easily changing the rotation speed rotation time data according to the amount of food to be cooked, the rotation speed of the rotating body can be changed according to the amount of food to be cooked. Even if the setting of the rotation speed or operating time changes irregularly, it can be converted to the rotation speed or operating time according to the quantity with a simple operation, and there is no need to store the data in the control unit with new key operations etc. Furthermore, the conventional disadvantages of having to cook in several batches when cooking for a large number of people, and wasting ingredients unnecessarily when cooking for a small number of people can be overcome, and this has a great practical effect.
