Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooking machine such as a food jotz twer that does not require cooking such as cutting, stirring, or mixing of meat, vegetables, fruits, etc., and its driving source. This relates to the drive control mechanism of the motor.

BACKGROUND ART Conventional 2-dot jotters provide a t-ter with a constant rotational speed from the start to the end of cooking, regardless of the quality of the cooking. In addition, by slightly improving this, we set up the cooking process by setting the rotating speed and operating time of the seven-turner to suit the various ingredients to be cooked, and equipped it with a microfuge unit that recorded the cooking process as data. The finished state is not constant depending on the output signal. Therefore, once you start the cooking process with the 11th operation, you will end up with two mistakes, such as cutting the ingredients to be cooked into smaller pieces than you had planned. In order to maintain a constant finish, the only option was to cultivate the intuition of carving into two sub-cooks, and judge the doneness of the cooking based on this intuition.Also, the drive of the tertiary machine had no choice but to maintain the accuracy of the cooking process with differences in the order of seconds. Since the finish of the material is affected, it is necessary to stop the machine more times than necessary and check the finish each time.

Purpose of the Invention The present invention has been made in view of the above-mentioned deficiencies found in the prior art. It is an object of the present invention to provide a cooking machine that automatically controls the Tanabata drive based on the judgment.

The structure of the invention is such that a motor and its drive control unit are housed inside a main body case, a container is placed and engaged on the upper surface of the main body case, and the main body case and the container are passed through and rotated by the motor. A driving shaft is provided protruding inside the stainless steel, and a rotary body for cutting, stirring, mixing, etc. of the material to be cooked is attached to the drive shaft, and the size of the particles of the material to be cooked is determined in the main body case or container. A sensing body using a photosensor for determining the particle size is provided, and the sensing body is connected to the control section to control the drive of the particle according to the size of the particle.

Embodiment 10 A cooking machine according to the present invention will be described in detail with reference to the drawings, with reference to an embodiment of the hood sensor.

The hood of the first embodiment of the present invention (see Figure 1)
- indicates a seven-tar (
2) Place the partition plate (
4) It is placed on top. (5) is a rotation shaft rotated by the motor (2);
The drive shaft (3) and the speed reduction mechanism (6) are connected to each other. This rotation shaft (51 is connected to the upper surface of the main body case (1), and the upper surface thereof (the transparent co7notener that is engaged with the two devices)
7) and projecting inside the container (7).

At the upper end of the rotating shaft (5), there are two upper and lower rotating bodies that cut, stir, and knead the ingredients to be cooked in the container (7).
A cutting body (9) with a stage cutter +81 +81 is mounted.

(1G is a lid having a material input portion 0υ, which is rotatably engaged with the upper end surface of the container (7) to prevent the material to be cooked from scattering.

Further, the bottom of the main body case (1) is closed with a bottom plate (1z).

Although not particularly shown in the drawings, this hood sensor has a drive speed control mechanism for the motor (2) consisting of electronic components such as a transistor and an iris register inside the main body case (1), and a drive speed gator for the motor (2). and one thousand v micrometers for respectively storing operation time data and outputting the stored data to the drive speed control mechanism,
It constitutes the drive control section 03 of the motor (2).

Further, the main body case (1) has an input and display section side consisting of a ten-switch unit for inputting the data, and a display section such as a light emitting diode for displaying the data in a timely manner.

In this first embodiment, a reflective photo sensor (151) as a sensor for sensing the size of particles of the material to be cooked is installed inside the upper surface of the main body case (1).
) Installed close to the bottom, the photo sensor-09
is connected to the control and wholesale department. This photo sensor: , Jter u9 is the light emitting diode α0 and the light emitting diode
It is composed of a light-receiving transistor (u) that turns on and off according to the ti and OFF operations.

The above-described connector (2), the drive control section 03, the input and display section (141), and the photo sensor (151) are connected as shown in FIG.

Figure 6 shows the reflection type photosessor housing in the main body case (
1) A second embodiment in which the container is located inside the container (7) and close to the side surface thereof.

The reflective photothesis sensor 9 used in the first and second embodiments irradiates light from the light emitting diode (161) onto the particles a& of the material flowing inside the container (7), and bounces off the particles αa. The incoming light is received by the phototransistor αη, and the difference between the time of irradiation and the time of reception of the light is converted into a rectangular wave pulse period, and a signal is sent to the control unit to notify the presence of particles. Since the number of ON times of the light emitting diode (161) is constant, when the material particles are rough and large and the density is low (Fig. 6 (
(See Fig. 6 (0)), the frequency of turning on the light receiving transistor aη is low, and the time it takes to turn on in one cycle is long (see Fig. 6 (0)).
reference). As the cooking progresses and the particles gradually become finer (see Figure 6 (, ``+1, rule)), the time that the light receiving transisister Qη is turned on becomes shorter, and instead, the frequency of turning on increases (see Figure 6). Figure (:), (see ~).Here, the time taken by the light receiving transistor (C of lη) depends on the length (L) in the particle flow direction (marked by an arrow), and also depends on the focal point of the light. :The focus of the photo sensor (151) is kept constant so that only the particles flowing into the JIJ bell are detected by the photo sensor (15). Of course, the light emitted from the light emitting diode α6) not only hits particle u81, but also hits koshide 'j'-471 and force/inter +81
181 and is reflected, and reception is stopped by the light-receiving transistor η. Therefore, the detection position accuracy of the sensor (151) is arbitrarily set so that anything other than particles is automatically excluded.

FIG. 6 (01, mouth, (~) said light receiving transistor (17
) is sent to the control unit (13) and analyzed, and the number of pulses per unit time corresponding to the degree of doneness of particles that matches the cooking process manually controlled by the switch group is analyzed. For example, if the output waveform from the sensor (15+) does not reach the specified completion level of the cooking process, continue cooking, but when the standard level is reached, Even in the middle of the cooking process, the drive of the rotor (2) is immediately stopped and the cooking is completed to provide the best finished product for the designated logical process in any case.

Fig. 7 shows an example of the S filter of the present invention, which uses a transmission type 7-ton υ-(A) as a sensor, and is common to the first and second embodiments described above. To explain without omitting the details, a transmission type transistor consisting of a light emitter Code (16) and a light receiving transistor anx is buried inside the side wall (marked 2) of the container (7), The container (7
) A recess (221) is provided in the bottom circumferential wall to extend the lead (c) from the photo hinge (20), and a terminal tl!
When a is protruded and rotatably coupled to the main body case (1) of the container [71'2], the photosensor (IJO) and the control a11 are connected.

In the transmission type photon, 4 lines (25) are formed between the light emitting tie code θe and the light receiving transistor a, and when a particle passes through these 417 lines (251), the light emitting diode becomes 0 mark. The light emitted from the light-receiving transistor 7) is blocked, and depending on the size of the particle, an output waveform similar to that of the reflective photosensor 05) (8th
Figures (o), (:), (see Figures) are confirmed, and these are analyzed and compared with the basic σ1μ waveform to control the drive of the t-tar (2). Therefore, there is no need for correction based on reflections from other parts like in the case of a reflective cabinet.

Effects of the Invention As described above, the present invention has a device that engages a container with the 14 sides of a main body case comprising a t-wheel and its drive control unit, and has a rotation drive driven by the t-tar inside the container. In addition to being attached to the body, a sensing body for determining the size of particles of the material to be atomized is provided in the container or the main body case, and the sensing body is connected to the control unit to control the drive of the motor. It automatically detects the doneness of the ingredients, and also automatically controls the motor drive speed that matches the conditions at that time, so that cooking can always be completed with the optimal result simply by selecting the desired cooking process. This eliminates the hassle of checking the doneness of ingredients during cooking. Also, since the finish is determined by the size of the particles, there is no need to worry about the finished product being affected by the amount of ingredients. Furthermore, since the Photo T-J sensor is installed inside the main body case or inside the side wall of the container, it can be easily configured without any special waterproofing treatment.
