Description

[Detailed Description of the Invention] Industrial Application Field The present invention is a food bar for cutting and pressurizing meat, vegetables, and fruits.
Related to cooking machines such as Koselli, motor-based)
This is concerned with the operation control mechanism of the rotating body of the cooking machine that is driven.

When mixing flour, water, etc. using a conventional cooking machine, the flour remains powdery immediately after cooking begins, and as kneading progresses, the viscosity increases and the load on the motor increases. Therefore, in the past, the motor was set at high speed (3
It is continuously driven at a speed greater than 300 rpm or at a medium speed (220 rpm). However, if the motor is driven at high or medium speed from the beginning, the rotating body will scatter the powder in all directions, and the powder will stick to the material input port around the container and will not mix with the water. , I was wasting the materials I used. Also, if the motor was driven continuously at medium speed at once, the mixture would be uneven and the finished product would not be good.

Purpose of the Invention The present invention was made in view of the above-mentioned drawbacks of the prior art.It is an object of the present invention to prevent the ingredients from scattering and to obtain a uniform mixture by giving the motor a rotational speed suitable for the ingredients to be cooked. There are things to do.

Structure of the Invention The present invention has a key power section, a display section, and a buzzer arranged on the front.
- a cooking container placed on the top surface of the base and having a rotating body inside; the rotating body is controlled and driven by a control signal from a control IJj path section housed inside the base; In a cooking machine that can be configured with a motor that has three rotational speeds consisting of medium speed and high speed, the motor is driven to rotate along a cooking process that can be comprised of several steps depending on the combination of the rotational speed and operating time. , Immediately after the start of cooking, low-speed intermittent driving is performed for a certain period of time at intervals of 0.5 seconds to 2 seconds, and then, after the low-speed intermittent movement has been transitioned to high-speed intermittent movement, medium-speed driving is performed. The drive is performed repeatedly at low speed C.

EXAMPLE Below, an example of the cooking machine of the present invention, which is a food processor, will be explained with reference to the drawings.

(↓) is the main body case, which consists of a vertically erected motor housing (2) and a base (3) that houses power transmission members and various electrical components. A cooking container (4) made of transparent resin is placed and engaged on the upper surface of this base (3), and a material input port (5) is provided vertically at the upper opening of the container (4). The lid (6) is fully fitted.

A cutting blade (7) is provided in the container (4) for cutting the food to be cooked that is put into the container (4). This cutting blade (7) is rotated by a motor (M) installed inside the base (3).

A key manual section (8), a display section (9), and a buzzer (10) are arranged on the front surface of the base (3). This key human power part <8) is the weight (P), the low speed key (LS) which gives 1600 rpm as the 1j11 rotation speed of the motor, 25

(10) has its surface covered with a cover (12) made of flexible soft vinyl chloride or the like. This cover (12
) has its end welded or glued to the base (3), and its surface is printed to correspond to each key switch, so that you can tell which switch it is by looking at it. The cover (12) can prevent water from entering the key manual part (8) in the second type of node blowing where water or the like is used. Since it can also be insulated from the outside, the risk of short-circuit accidents is extremely low.

Next, the control circuit for the motor (M>) will be explained.

First, the motor (M) is connected to an alternating current power source (AC) together with a triac (TA). There is a prill rectifier (BD) on the gate side of this triac (TA).

PH) is composed of a light emitting diode (LEDI) and a 'swirlistor (S'CR), and there is no electrical connection, and it only starts when the light emitting diode (LEDI) turns on and emits light. The thyristor (SCR) is a switching element that is turned on by the optical technology.

(Z) is a noise sampling element, which removes various radio waves superimposed on the electric i1 [waveform] entering the E-tar (M), and also removes various radio waves superimposed on the waveform of the electric current input to the E-tar (M), and also detects the triangularly connected conde laser group (TC) and the -I capacitor. (CI) Removes the slight M sound that could not be removed by C2> and Gitan (R1), etc., and provides stable drive to the motor (M). In particular, the CR circuit, which is composed of a resistor (R1), a capacitor (C'l), and a
This function is to prevent mis-triggering of the gate signal entering the gate.

(MC) is a one-chip microcomputer with a memory unit corresponding to the brain of the computer, 4-bit RAM and ROM, and is manually operated by the key human power department (7). It stores data and outputs control signals based on the data at any time to control the speed and operating time of the motor (M).The photocoupler (PH) is connected to the motor (M) via a transistor (TRI). and is connected to the output port (PG\) of the microcomputer (MC).

Drive-4. 1600r every 1.5 seconds after the start of driving
111n low-speed intermittent drive @ 1J lasting 9 seconds. During this time, the water and flour are mixed roughly using a gentle force, without the ingredients scattering around the circumference of the container <4) or near the material input port (5), and the water and flour are combined into a ball. Crush the shaped material using intermittent motion and disperse it over the dry flour. Therefore, scattering of powder and materials is reduced, and areas containing moisture are evenly distributed. Continued-
C3300rpm high-speed intermittent drive for 9 seconds6
This process repeats the process of making the material into a lump and then crushing it again with the cutting blade, which evens out the moisture throughout the flour and adds partial kneading to the material.

After this, the cooking pattern moves to the next stage 4b).

That is, the motor (M) is continuously driven at medium speed (250 rpm) for 35 seconds. The flour and water are mixed almost uniformly by the previous two drive patterns, and by this drive pattern, the material is kneaded vigorously as a whole by the cutting blade (7). (
M> can be driven alternately at low speed and high speed at regular intervals,
The pattern shown in Figure 4 (the movement of the kneaded wood ↓) causes the entire material to be kneaded uniformly. For ingredients that do not require 2, you can use the motor (M>) and λ to continue the low speed intermittent drive and 1.41 speed intermittent drive at medium speed until the end of cooking.

Effects of the Invention The present invention provides a key manpower section, a display section, and a slot on the front.

Composed of a motor with a rotational speed of 'C! i; In a cooking machine, the motor operates according to the combination of its rotational speed and operating time (according to the cooking process).
2. Rotate and drive immediately after starting cooking: o, 5 seconds to 2
Low-speed intermittent driving is performed for a certain period of time at second intervals, and then the low-speed intermittent driving is changed to high-speed intermittent driving. Efficiently cutting and stirring -C', the effect is especially noticeable for cooking materials that increase in axiality when mixed.
A uniform finish can be obtained.
