The ultrasonic sliding module 1 comprises a transmission unit 11, an ultrasonic sensor unit 12 and a micro switch unit 13, wherein the ultrasonic sensor unit 12 is slidably mounted on the transmission unit 11, and the micro switch unit 13 is mounted at two ends of the transmission unit 11.
In this way, the ultrasonic sensor unit 12 is slid left and right by the transmission unit 11, and the microswitch unit 13 is touched, whereby the code wheel module 2 starts or stops generating the pulse signal.
The transmission unit 11 comprises a belt 111, a belt rotating shaft 112 and a sliding rod 113, the belt 111 is sleeved between the belt rotating shaft 112 and a rotating part of the code wheel module 2, the sliding rod 113 is installed below the belt 111, and the ultrasonic sensor unit 12 is installed on the belt 111 and penetrates through the sliding rod 113.
Thus, the rotation of the belt 111 and the belt rotation shaft 112 drives the ultrasonic sensor unit 12 to slide left and right on the slide bar 113. The belt 111 is sleeved between the code wheel rotating shaft 22 and the belt rotating shaft 112 to play a role of transmission linkage.
The ultrasonic sensor unit 12 includes an ultrasonic transmitter 121, an ultrasonic receiver 122, and a slider 123, and the ultrasonic transmitter 121 and the ultrasonic receiver 122 are both mounted on the slider 123.
In this way, the ultrasonic wave is transmitted to the food by the ultrasonic transmitter 121, and the ultrasonic wave is received by the ultrasonic receiver 122, so that the distance from the sensor to the food is judged by the time from the transmission to the reception of the ultrasonic wave.
The micro switch unit 13 includes a first micro switch 131 and a second micro switch 132, and the first micro switch 131 and the second micro switch 132 are respectively installed at both ends of the sliding rod 123.
Thus, the pulse signal is generated by turning on the code wheel module 2 through the first microswitch 131, and the pulse signal is generated by turning off the code wheel module 2 through the second microswitch 132, so that a complete acquisition cycle is formed.
The code wheel module 2 comprises a code wheel unit 21, a code wheel rotating shaft 22, a code wheel motor 23 and an infrared unit 24, wherein the code wheel rotating shaft 22 is installed at the center of the code wheel unit 21 and is respectively sleeved at two ends of the inner part of the belt 112 together with the belt rotating shaft 112, the rotating part of the code wheel motor 23 is connected with the code wheel rotating shaft 22, the infrared unit 24 is perpendicular to the code wheel unit 21, and the edge of the code wheel unit 21 penetrates through the inner part of the infrared unit 23.
Therefore, the code wheel motor 23 generates power to drive the code wheel rotating shaft 22 and the code wheel unit 21 to rotate, the edge of the code wheel unit 21 penetrates through the inside of the infrared unit 23, and transmission of infrared rays is blocked or conducted, so that a pulse signal is generated.
The infrared ray unit 24 includes a fixing member 241 with a groove, an infrared ray emitter 242 and an infrared ray receiver 243, the infrared ray emitter 242 and the infrared ray receiver 243 are oppositely installed in the groove of the fixing member 241, and the edge of the code wheel unit 21 passes through a connecting line where the infrared ray emitter 242 and the infrared ray receiver 243 are oppositely installed without interference.
Thus, infrared rays are emitted through the infrared emitter 242 and received through the infrared receiver 243, so that a pulse signal is generated by blocking or conducting transmission of infrared rays through the edge of the code wheel unit 21 through the connecting line where the infrared emitter 242 and the infrared receiver 243 are oppositely installed.
The code wheel unit 21 comprises a code wheel body 211 and a plurality of code wheel holes 212, and the code wheel holes 212 are uniformly distributed on the periphery outside the code wheel body 211.
Thus, when the code wheel hole 212 of the code wheel body 211 passes through the connecting line oppositely arranged by the infrared emitter 242 and the infrared receiver 243, the controller can detect a high level because the shielded infrared receiving and transmitting are normal; when the code wheel hole 212 of the code wheel body 211 is not located at a connecting line where the infrared ray emitter 242 and the infrared ray receiver 243 are oppositely installed, the controller may detect a low level due to a failure of receiving the blocked infrared ray, and thus a pulse signal as shown in fig. 5 is formed. The code wheel body 211 is formed by punching a circular metal sheet, a code wheel rotating shaft 22 is arranged at the center of a circle, and the code wheel motor 23 can drive the code wheel rotating shaft 22 to rotate, so that the code wheel body 211 rotates.
The opening widths of the code disc holes 212 are the same, and the opening distances among the code disc holes 212 are the same.
In this way, the widths of the openings of the code disc holes 212 are the same, the widths of the generated pulse signals (i.e., the widths of the high levels) are the same, the intervals of the generated pulse signals (i.e., the widths of the low levels) are the same, and the fixed pulse signals having the same widths and the same intervals are generated, so that the periods of the pulse signals are the same, the durations of the high levels in each period T are the same, and the durations of the low levels are the same.
The working process is as follows:
a. when the ultrasonic sensor unit 12 slides to the left end, the elastic piece of the left first microswitch 131 is compressed and switched on, and the controller can detect that the ultrasonic sensor unit 12 reaches the left end.
b. When the ultrasonic sensor unit 12 slides away from the left first microswitch 131 to restore the elastic sheet, and the left first microswitch 131 is turned off, the controller detects that the ultrasonic sensor unit 12 leaves the left first microswitch 131, clears the number of pulses recorded before, that is, CNT is 0, and starts to record the number of pulses of the code wheel signal again, specifically: when the controller detects that the pulse signal changes from low level to high level, the number of recording pulses CNT is increased by 1.
c. During the rightward sliding of the ultrasonic sensor unit 12, the ultrasonic sensor unit 12 emits ultrasonic waves 1 time every time the CNT is increased by 1 and receives a return signal, forming the distance L from the ultrasonic sensor unit 12 to the food corresponding to the CNT value.
d. Similarly, when the ultrasonic sensor unit 12 slides to the right end, the elastic sheet of the second microswitch 132 on the right side is compressed and switched on, and at this time, the controller can detect that the ultrasonic sensor unit 12 has reached the right end, and end the data acquisition process of the step c to form a CNT-L data set.
e. In the sliding process of the ultrasonic sensor unit 12, the sliding displacement of the ultrasonic sensor unit 12 is increased by S every 1 pulse, so the controller can calculate the displacement DISTANCE (S CNT) of the sliding of the ultrasonic sensor unit 12 relative to the left end by detecting the pulse number of the code disc, and a data set of DISTANCE-L, namely, one-dimensional coordinate data (marked as X coordinate) can be obtained according to the relationship. f. After forming a data set of an X coordinate DISTANCE-L, the coded disc motor 23 controls the ultrasonic sensor unit 12 to slide to the leftmost side, the sliding process is equivalent to the reset of the position of the ultrasonic sensor unit 12, data acquisition is not carried out in the process, and the steps a to f are repeated after the reset.
Through the detection of the distance L from the ultrasonic sensor unit 12 to the food in the cooking process, the change of the volume and the shape of the food in the cooking process can be known, and intelligent cooking control can be realized by combining different food materials and menu requirements, so that the food can reach the optimal cooking degree and taste. For example: for baking, the baking degree can be judged by detecting the change of the volume of the food from small to large or the change of the shape; for roasted meat, the degree of maturity can be judged by detecting the change of the food volume from large to small.
According to the device for recognizing the degree of cooking of the food by using the ultrasonic waves, the distance from the ultrasonic sliding module to the food is detected, the code disc module generates the fixed pulse signal, so that the size of the food volume is obtained according to the distance from the ultrasonic sliding module to the food and the fixed pulse signal, the cooking effect is judged according to the change conditions of the food volume and the shape to recognize the degree of cooking, the detection latitude of intelligent cooking is increased, the cooking process is controlled more accurately, the intelligent degree of cooking is improved, and the user experience is improved.

In this way, the food is scanned inside the cooking device, two-dimensional coordinates are more accurate, and the device for identifying the degree of cooking of the food by using ultrasonic waves only describes X-coordinate data (namely scanning data of a first ultrasonic sensor unit of a surface BCFG in the figure), and scanning data of a second ultrasonic sensor of a surface HEFG is required to be added (the scanning method is the same as the above, and the scanning data is recorded as a Z coordinate). It should be noted that, after two ultrasonic sensor units in the inner cavity need to be in a reset state at the same time, two motors can start the control sensor to slide in the opposite direction and collect data at the same time, and after two ultrasonic sensors finish collecting and respectively form a DISTANCE-L data set of an X coordinate and a Z coordinate, the controller processes two-dimensional data: the X-coordinate describes the lateral data, i.e. circumference, of the food, and the Z-coordinate describes the longitudinal data, i.e. height, of the food.
Through the detection to the degree of enclosing and the height of culinary art in-process food, can know the change of food volume and shape in the culinary art process, combine different food material and menu requirements, can realize intelligent cooking control, make food reach best maturity and taste. For example: for baking, the baking degree can be judged by detecting the change of the volume of the food from small to large or the change of the shape; for roasted meat, the degree of maturity can be judged by detecting the change of the food volume from large to small.
