In other embodiments of the invention, cooking equipment may also include infrared detecting device, and infrared detecting device is used for The food materials in liner 10 are detected, ultrasound examination and infrared detection are combined as a result, detection performance can be improved.
The specific embodiment of the cooking equipment of the embodiment of the present invention is introduced below.
According to one embodiment of present invention, food materials information includes food materials distribution and water body distribution, and control device 40 is used for It is distributed according to food materials distribution with water body and determines optimal placement point, and the movement of ultrasonic detection device 20 is controlled by driving device 30 To optimal placement point.
For example, control device 40, which detects the food materials in liner 10 by ultrasonic wave, can determine that ultrasonic wave is examined The optimal placement point for surveying device 20 is that ultrasonic detection device 20 selects suitable set-point.Specifically, when utilize ultrasonic wave Cavitation, machinery, thermally and chemically effect, to container contents and container itself play sterilization, degasification, emulsification, foam removal, extraction, When washing, removing residual agriculture, cleaning, promote at least one of water suction and microcosmic crushing etc. function, ultrasonic detection device 20 is preferably It is partly or entirely contacted with the liquid in liner 10, to reach maximized energy transmission.It is more solid when having in liner 10 as a result, When state food materials (such as bulk potato, bulk taro, bulk meat etc.), ultrasonic wave is carried out by ultrasonic detection device 20 and is swept It retouches, available gap is larger and water body is distributed the i.e. optimal placement position in more position, and control device 40 can control later Ultrasonic detection device 20 is accurately launched to optimal placement position, and emits ultrasonic wave, arrives water body to guarantee smoothly to launch It is interior, it avoids being stopped by solid-state food materials, plays the function of ultrasonic wave to greatest extent.
For another example, control device 40, which detects the food materials in liner 10 by ultrasonic wave, can determine mixing time and stir Mix position.Specifically, control device 40 carries out ultrasonic scanning by ultrasonic detection device 20, and liner 10 can be monitored in real time The stackings of interior food materials, water body distribution and other real-time cooking informations, and according to the stacking of food materials in liner 10, water body distribution and its His real-time cooking information determine mixing time and stirring position, and control ultrasonic detection device 20 and connecting component 320 according to Determining mixing time and stirring position carries out ultrasound and/or stir process to food materials, thus guarantee food materials culinary art uniformly, stirring Timely and appropriate discovery is avoided be easy to causeing food materials to be charred or cook unevenly due to cannot timely and effectively stir, and is avoided due to stirring It mixes and excessively causes food materials morphological disruption or nutrition loss.
According to one embodiment of present invention, ultrasonic transmitting element 21 is also used to be moved in ultrasonic detection device 20 It is controlled when default test point in inside gallbladder 10 and emits ultrasonic wave;Ultrasonic wave receiving unit 22 is also used to receive through air/water interface First echo of reflection, and receive through the second echo of water/food materials interface reflection, and receive anti-by food materials/wall of inner container interface The third echo penetrated;Analytical unit 23 is also used to generate first detection signal according to the first echo, generates the according to the second echo Two detection signals generate third detection signal according to third echo;Wherein, control device 40 is according to first detection signal, second It detects signal and third detection signal calculates the ratio of food materials and water in liner 10, and according to the Ratio control liner of food materials and water Water in 10.
For example, food materials can be rice, and control device 40 detects the food materials in liner 10 by ultrasonic wave can be with Realize cooking rice automatic water equilibrium function.Specifically, suitable meter Yu Shui is added into liner 10.Cover the upper of cooking equipment Lid, ultrasonic transmitting element 21 issue ultrasonic wave, and when ultrasonic wave passes through air/water interface, portion of ultrasonic sound wave reflects, and first Echo is received by ultrasonic wave receiving unit 22, records data r1.When ultrasonic wave passes through water/rice interface, portion of ultrasonic sound wave occurs anti- It penetrates, the second echo is received by ultrasonic wave receiving unit 22, records data r2.When ultrasonic wave passes through rice/liner inner wall interface, part Ultrasonic wave reflects, and third echo is received by ultrasonic wave receiving unit 22, records data r3.Control device 40 to r1, r2 and R3 is handled, and the ratio of meter Yu Shui in liner 10 is finally calculated.
More specifically, control device 40 can compare the ratio of food materials and water and default ratio range, and according to than Relatively result controls water.By taking the ratio k of meter Yu Shui as an example, if k value is greater than the upper limit value of default ratio range, illustrate that rice contains To measure excessively high, this result can be fed back to water balance device by control device 40, and water balance device controls water tank into liner 10 plus water, Until k value is fallen within default ratio range, start rice-cooking function later.If k value is less than the lower limit value of default ratio range, Then illustrate that water content is excessively high, this result is fed back to water balance device by control device 40, and water balance device controls water tank, by liner Water in 10 is taken away, or control device 40 this result is fed back into rice bin controller, control rice bin adds rice into liner 10 Amount.Until k value is fallen within default ratio range, start rice-cooking function later.If k value is fallen within default ratio range, Then directly initiate rice-cooking function.
Further, according to one embodiment of present invention, ultrasonic wave receiving unit 22 is also used to receive through water/wall of inner container 4th echo of interface reflection;Control device 40 ultrasonic wave receiving unit 22 do not receive the first echo or the second echo or Judge that dry combustion method occurs for cooking equipment when four echoes.
For example, control device 40, which carries out detection to the food materials in liner 10 by ultrasonic wave, may be implemented anti-dry function Energy.Specifically, during the cooking process, ultrasonic detection device 20 can constantly issue ultrasonic wave, when air/water interface echo or When the echo of person's water/solid contactant (solid contactant includes food materials or liner inner wall) completely disappears, illustrate in liner 10 Water has dryouied.Control device 40 judges that dry combustion method occurs for cooking equipment at this time, and the heating device for controlling cooking equipment disconnects, and stops Heating, to prevent cooking equipment dry combustion method and cause danger.
To sum up, ultrasonic wave occurs into liner for the cooking equipment proposed according to embodiments of the present invention, ultrasonic detection device, And the echo of reflection being received, and detection signal is generated according to the echo of the reflection received, driving device drives ultrasonic wave inspection It surveys device and is moved at least one detection position, control device acquisition when ultrasonic detection device is moved to each detection position Corresponding detection signal, and according to the food materials information in corresponding detection signal acquisition liner, it is cooked so as to accurately detect The food materials prepared food in equipment, and under high-temperature cooking environment and there are also can be real when steam, smog and the disturbing factors such as unglazed Food materials are now accurately detected, the experience of user is promoted.
