Description

Technical Field

[0001] The invention relates to a frying and stewing machine and a control method thereof, belonging to the technical field of kitchen appliances. Background Art

[0002] During the cooking process, in order to maintain the temperature of the ingredients in the pot, the chef needs to cover the pot with a lid. Since the ingredients will evaporate into gaseous water vapor during the heating process, when the steam condenses in large quantities on the colder pot lid, it will turn into hot water droplets. When the user lifts the pot lid, the water droplets will flow out of the pot lid, which may scald the user's arm or flow onto the stove or the ground, causing health and safety hazards. In addition, in order to ensure that both sides of the ingredients are cooked, the user needs to turn the ingredients over in a timely manner during the cooking process so that the other side can also be heated. However, this manual turning method is not only cumbersome, but the turning time is also inevitably subject to errors, which can easily lead to uneven heating of the two sides of the ingredients, and one side may be burnt while the other side is uncooked. Moreover, when heating the ingredients, it is generally necessary to add water to the ingredients in a timely manner to prevent the water in the pot from being burned dry. The current method of adding water generally requires the user to first open the lid of the container and then manually pour water into the container. This method is relatively cumbersome and the amount of water added is difficult to control. Summary of the Invention

[0098] A control method for the above-mentioned frying and stewing machine includes the following steps:

[0099] The frying and stewing information of the object to be processed is retrieved and obtained; the frying and stewing information includes a preset frying and stewing temperature time-shift curve and frying and stewing rules.

[0100] According to the frying and stewing information, the far-infrared heating structure and the heater are controlled to fry and stew the object to be processed, and the actual temperature information is collected in real time.

[0101] According to the actual temperature information and the preset frying and stewing temperature time-shift curve, the far-infrared heater temperature and the heater temperature are adjusted respectively; so that the difference between the actual temperature at the center of the top surface of the food, the actual temperature at the four corners of the top surface of the food and the preset temperature at the center of the top surface of the food, the preset temperature at the four corners of the top surface of the food corresponding to the preset frying and stewing time-shift curve is less than the preset threshold, and the actual temperature at the center of the top surface of the food and the actual temperature at the four corners of the top surface of the food tend to be consistent.

[0102] The far-infrared heater temperature and the heater temperature are adjusted according to the actual temperature information and the preset frying and stewing temperature time-shift curve as follows: if the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are higher than the preset temperature of the center of the top surface of the food and the preset temperature of the four corners of the top surface of the food, the actual far-infrared heater temperature and the actual heater temperature are lowered according to the preset far-infrared heater temperature and the preset heater temperature; if the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are lower than the preset temperature of the center of the top surface of the food and the preset temperature of the four corners of the top surface of the food, the actual far-infrared heater temperature and the actual heater temperature are increased according to the preset far-infrared heater temperature and the preset heater temperature.

[0103] The temperature of the bottom surface of the food is collected in real time, and it is determined whether the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are close to the temperature of the bottom surface of the food; if the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are close to the temperature of the bottom surface of the food, the heating temperature of the far-infrared heater and the heater is kept unchanged.

[0104] The present invention has a simple structure. Compared with the existing technology, the cover body can form an angle with the pot under the action of the secondary folding arm structure, so that water droplets on the inner wall of the cover body flow back into the pot, thereby reducing the occurrence of scalding users and contamination of the stove. Moreover, because the present design adopts a secondary folding arm structure, it has a larger variable angle and the cover body can rotate to a larger extent. Compared with the existing manual water adding method, the present design can automatically add water to the ingredients being cooked under the action of the water pump, and can also control the operating speed of the electric pump through the circuit to adjust the time and amount of each water adding, which is quick and convenient to operate. In addition, the reflector on the far-infrared heating structure can reflect part of the radiation energy that the ingredients have not absorbed in time and feed it back to the ingredients, thereby greatly improving the energy utilization rate. Since a heat dissipation chamber is added, the reflector cover can dissipate heat in time during use, thereby avoiding the occurrence of excessive temperature. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0144] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0145] like Figure 1-Figure 34As shown: A frying and stewing machine includes a base 1, a heater 69 is provided on the base 1, and a container 2 is placed on the heater 69. A secondary folding arm structure is hinged on the base 1, and the end of the secondary folding arm structure is fixedly connected to a cover 11 that can cooperate with the container 2. The cover 11 is driven to rotate by the secondary folding arm structure, and a far-infrared heating structure for heating the top surface of the food is fixedly connected to the bottom of the cover 11 (in order to make the cooperation between the cover 11 and the container 2 better, a first sealing ring 16 can be provided on the outer edge of the cover 11, which can prevent the loss of heat inside the container 2). It also includes a control The device comprises a control device, wherein the control device is electrically connected to the heater 69 and the far-infrared heating structure respectively, and the control device is used to adjust the temperature of the heater 69 and the far-infrared heating structure respectively. A water tank 3 is also provided on one side of the base 1, and the water tank 3 is provided with a liquid transmission structure that can transport liquid to the interior of the container 2; when the cover 11 needs to be opened from the container 2, it will form an angle with the container 2 under the action of the secondary folding arm structure, so that the liquid on the inner wall of the cover 11 flows into the container 2, and when water needs to be added to the container 2, the water in the water tank 3 can flow into the container 2 by controlling the liquid transmission structure.

[0146] A water inlet is provided above the water tank 3, and a rotatable water tank cover 4 is provided on the water inlet. A water outlet is provided below the water tank 3. The liquid transmission structure includes a water outlet mechanism, a water pump 7 and an output pipe 8. The water outlet mechanism is arranged below the water outlet and is interconnected with the water pump 7. The water pump 7 is also connected to an output pipe 8, and the end of the output pipe 8 extends from the outside of the cover body 11 into the container 2; when the water in the water tank 3 flows out from the water outlet to the water outlet mechanism, it will flow from the output pipe 8 into the container 2 under the action of the water pump 7.

[0147] The water outlet mechanism is a one-way valve 5, one end of which is connected to a water pump 7 via a connecting pipe 6. The water pump 7 is controlled by a circuit, and the water pump 7 and its control switch are electrically connected (the control switch is not shown in the figure, and the water pump 7, the control switch, and the circuit for controlling its operation are all prior art). The water pump 7 is also connected to an output pipe 8 (the connecting pipe 6 and the output pipe 8 are both flexible pipes). A second hole 61 is provided on the cover 11, and the end of the output pipe 8 extends from the second hole 61 of the cover 11 into the container 2. , and a nozzle 9 with atomization and direct spraying functions is also provided at the end of the output pipe 8, and the nozzle 9 is fixed below the second hole 61; when the water in the water tank 3 flows out from the water outlet to the one-way valve 5, it will flow from the output pipe 8 into the container 2 under the action of the water pump 7. By controlling the circuit of the water pump 7, the time and amount of water addition can be adjusted (the principle of using the circuit to control the action of the water pump 7 is also a prior art, and those skilled in the art only need to design the relevant circuit according to actual needs, so this article will not go into details about it).

[0148] The one-way valve 5 includes a valve body 29, a sealing gasket 30, a spring 31 and a sliding rod 32. The sealing gasket 30 is a silicone sealing gasket. The top surface of the valve body 29 is provided with an opening, and a water outlet cavity is formed inside. One side of the water outlet cavity is provided with a water outlet column 33 connected to the water pump 7. The water outlet column 33 and the water pump 7 are connected by a connecting pipe 6. The valve body 29 is fixedly connected to the base 1, the water tank 3 is arranged above the opening of the valve body 29, and its water outlet is pluggable and arranged in the water outlet cavity of the valve body 29. A push rod 34 is fixedly arranged in the water outlet cavity of the valve body 29, and a support component 35 is provided on the water outlet of the water tank 3. A leakage hole is opened on the support component 35, and the slide rod 32 is liftable and connected to the support component 35. The top end of the slide rod 32 passes through the support component 35 and is fixedly connected to the sealing gasket 30. The end of the slide rod 32 is connected to the bottom surface of the support component 35 by a spring 31 and is located directly above the push rod 34 (when the water tank 3 is installed on the base 1, the valve body The push rod 34 of 29 will push the slide bar 32 upward, separating the sealing gasket 30 and the water outlet of the water tank 3 from each other. Water will flow from the leaking hole of the support component 35 into the water outlet cavity of the valve body 29, and then from the water outlet column 33 to the water pump 7. Finally, under the action of the water pump 7, it will flow from the output pipe 8 into the container 2. At this time, the spring 31 is in a compressed state; when the water tank 3 is lifted and separated from the base 1, the slide bar 32 will lose its compression, and the spring 31 will recover, driving the slide bar 32 downward, so that the sealing gasket 30 and the water outlet of the water tank 3 are in contact with each other, thus sealing the water tank 3 and preventing water from flowing out of the leaking hole of the support component 35. At this time, the spring 31 is in a normal state.

[0149] The secondary folding arm structure 10 includes a first folding arm 17 that can drive the cover body 11 to rise and fall and a second folding arm 18 that can drive the cover body 11 to rotate. The base 1 is provided with a lower recess 26, and a hinge seat 25 is provided on the lower recess 26. One end of the first folding arm 17 is hinged to the hinge seat 25 through a first rotating shaft 23, and the other end is hinged to the second folding arm 18 through a second rotating shaft 24. The cover body 11 is locked and fixed to the bottom of the end of the second folding arm 18 by a fourth screw 63; when the first folding arm 17 rotates, it will drive the second folding arm 18 and the cover body 11 to move up and down. When the second folding arm 18 rotates, it will drive the cover body 5 to rotate around the second rotating shaft 11, so that the cover body 11 and the container 2 form an angle of 0°-120°, so that the liquid on the inner wall of the cover body 11 flows into the container 2.

[0150] The second folding arm 18 includes a hinged section 27 hinged to the first folding arm 17 and a fixed section 28 fixedly connected to the cover body. The hinged section 27 and the fixed section 28 are integrally formed, and an angle α of 120° is formed between the hinged section 27 and the fixed section 28; a scalding prevention component 19 is also provided under the fixed section 28 of the second folding arm 18. The user can lift the second folding arm 18 through the scalding prevention component 19 to open the cover body 11. Since the hand only contacts the scalding prevention component 19, the occurrence of scalding can be reduced (the scalding prevention component 19 can be a rubber pad with scalding function).

[0151] A temperature measuring component 22 (the temperature measuring component 22 may be a thermistor) is further provided below the fixed section 28 of the second folding arm 18, and a first hole 21 is provided on the cover body 11 for the temperature measuring component 22 to pass through. When the cover body 11 is fixed below the fixed section 21 of the second folding arm 18, the temperature measuring component 22 will pass through the first hole 21 on the cover body 11 and extend into the container 2, thereby detecting the temperature inside the container 2 (the temperature measuring component 22 belongs to the product of the prior art and will not be described in detail herein).

[0152] The first folding arm 17 and the second folding arm 18 are both provided with a through cavity, and the output pipe 6 is arranged in the cavity, the end of which extends from the cavity of the second folding arm 18 and extends into the hole of the cover body 11, and finally the water is evenly sprayed inside the container 2 by the nozzle 9 (this can avoid the output pipe 8 being completely exposed to the outside of the machine, reduce the occurrence of pollution, and also improve the cleanliness of the machine).

[0153] The base 1 is provided with a housing chamber, in which the valve body 29 of the one-way valve 5 and the water pump 7 are fixedly mounted (a sunken mounting hole 15 is provided on the mounting position 12 of the base 1, in which the one-way valve 5 is mounted, and the water pump 7 is fixed to the inner wall of the housing chamber). A second sealing ring 36 is provided between the valve body 29 and the sunken mounting hole 15. The output pipe 8 is connected to the water pump 7 within the housing chamber and laid within the cavity of the secondary folding arm structure 10, ultimately extending from the cover 11 into the container 2 (this maximizes the utilization of the internal space of the machine). The base 1 is also provided with a mounting position 12, on which the water tank 3 is mounted. To enable the water tank 3 to be quickly and accurately mounted on the mounting position 12 of the base 1, a sunken positioning groove 13 can be provided on the mounting position 12, and a corresponding raised positioning block 14 can be provided on the water tank 3.

[0154] In order to further improve the neatness of the machine, the hinge seat 25 can also be designed to be hollow inside and have through holes on both sides, so that after the output pipe 8 is connected to the water pump 7 in the accommodating chamber, it can extend from the hinge seat 25 and pass through the cavities of the first folding arm 17 and the second folding arm 18 in turn, and finally be connected to the nozzle 9 fixed on the inner side of the cover body 11. In this way, most of the output pipe 8 can be hidden in the internal space of the machine, reducing the occurrence of exposure to the outside and contamination, and also improving the aesthetics of the machine.

[0155] The cover body 11 is provided with a through hole, and an annular protective cover 42 is fixedly arranged below the through hole. The annular protective cover 42 is a stainless steel reflective cover, and the top edge of the annular protective cover 42 forms a flange 43 outward. The annular protective cover 42 is fixedly connected to the cover body 11 through the flange 43 and is arranged directly below the through hole. A light-transmitting microcrystalline plate 44 is fixed to the bottom of the annular protective cover 43 through silicone (using silicone for fixed connection can enhance sealing and prevent water vapor from entering during use). The cover body 3 is fixedly connected with a reflective cover 45, which is an aluminum reflective cover. The reflective cover 45 is arranged inside the annular protective cover 22, and a far-infrared heater 20 is fixedly arranged between the reflective cover 45 and the light-transmitting microcrystalline plate 44. A heat dissipation shell 37 is fixedly arranged above the through hole, and a first heat dissipation hole 38 is provided on the side of the heat dissipation shell 37. The heat dissipation shell 37 and the cover body 11 are combined to form a heat dissipation chamber.

[0156] A heat sink 39 is fixedly provided on the through hole of the cover body 11, and a plurality of second heat dissipation holes 40 are provided on the heat dissipation plate 39 (the second heat dissipation holes 40 can make the heat emitted by the reflector 45 flow evenly to the heat dissipation chamber). An L-shaped fixing plate 41 is provided below the heat dissipation plate 39. The L-shaped fixing plate 41 and the heat dissipation plate 39 are integrally formed. The reflector 45 and the heat dissipation plate 39 are fixedly connected by the mutual cooperation of the third screw 62 and the screw hole on the L-shaped fixing plate 41; the far-infrared heater 20 is a far-infrared heating tube, which is fixedly connected to the inner side of the reflector 45 by a retaining spring 46.

[0157] The flange 43 of the annular protective cover 42 is also provided with a third sealing ring 47. When the annular protective cover 42 is fixedly connected to the cover body 11, the third sealing ring 47 is located at the connection between the annular protective cover 42 and the cover body 11 and fits with the cover body 11, thereby preventing water vapor from entering the interior of the annular protective cover 42 through the gap during heating.

[0158] In order to speed up the heat dissipation of the reflector 45, a heat dissipation acceleration component can also be set inside the heat dissipation shell 37, so as to speed up the air circulation speed of the heat dissipation chamber (such as a heat dissipation fan, which is not shown in the figure; such components belong to products in the existing technology and will not be described in detail in this article).

[0159] In order to enhance the stability of the overall structure, an assembly screw hole 68 can be provided on the top surface of the heat dissipation shell 37, and a corresponding assembly screw 67 can be provided on the fixed section 28 of the second folding arm 18, and a first cover plate 66 is provided on the top surface of the fixed section 28 of the second folding arm 18. Opening the first cover plate 66 can expose the cavity inside the second folding arm 18, and the assembly screw 67 can be locked on the assembly screw hole 68 through the exposed cavity, so that the fixed section 28 of the second folding arm 18 and the heat dissipation shell 37 are fixedly connected.

[0160] The side wall of the container 2 is also provided with a scalding-proof gripping component 64, and the gripping component 64 includes an integrally formed handle 48 and a handle seat 49. One side of the handle seat 48 is provided with an opening, and a first cavity is formed inside. Positioning blocks 50 are respectively provided at the upper and lower ends of the side wall of the container 2. The handle seat 48 is fixedly connected to the positioning block 50 by a first fastening structure and is suspended on the side wall of the container 2. The side of the handle seat 48 with the opening contacts the side wall to form a first heat-insulating chamber; by reducing the contact area between the gripping component 64 and the side wall, the heat transferred from the side wall to the gripping component 64 can be reduced.

[0161] The first fastening structure described above includes a first screw 51 and a nut 52. The nut 52 is a square nut and is arranged behind the positioning block 50. The first screw 51 passes through the handle seat 49 and the positioning block 50. The handle seat 49 is fixedly connected to the middle end of the positioning block 50 through the locking fit of the first screw 51 and the nut 52 and is suspended on the side wall of the container 2. The positioning block 50 is in a "Ji" shape. The left and right ends of the positioning block 50 are integrally formed with the side wall, and the middle end protrudes outward. The nut 52 is arranged behind the middle end of the positioning block 50. A third hole 65 is further provided at the middle end of the positioning block 50 for the first screw 51 to pass through.

[0162] Fastening positions that cooperate with the first screw 51 are respectively provided at the upper and lower ends of the handle seat 48. The fastening position at the lower end of the handle seat 48 is a positioning hole 53, and the fastening position at the upper end is a straight slot 54 (due to the processing technology of the container 2, certain deviations may occur after it is processed into a finished product, and it is not easy to ensure the distance between the third holes 65 between the two positioning blocks 50 on its side wall. Therefore, some allowances need to be left on other structural parts for installation and cooperation).

[0163] It further includes a rear cover 55 fixedly connected to the handle 48 through a second fastening structure. The handle 48 and the rear cover 55 form a second heat insulation chamber. The second fastening structure includes a second screw 56. The handle 48 is provided with a mounting post 57 that can cooperate with the second screw 56. Threads that cooperate with the second screw 56 are provided inside the mounting post 11. A second cover plate 58 is further provided on the rear cover 55 (after the second screw 56 is locked, it is blocked by the second cover plate 58 to prevent the second screw 56 from being exposed outside, which can improve the aesthetics of the machine and also reduce the occurrence of the second screw 56 being corroded by contacting the outside).

[0164] Openings are provided on one side where the handle 48 and the rear cover 55 are combined with each other, and second cavities are formed inside both of them. The two are combined to form a second heat insulation chamber. A number of reinforcing ribs 59 are provided in the first cavity of the handle seat 48, the second cavity of the handle 48, and the second cavity of the rear cover 55. The reinforcing ribs 59 include transverse reinforcing ribs and longitudinal reinforcing ribs, and the transverse reinforcing ribs and the longitudinal reinforcing ribs are arranged alternately (the reinforcing ribs 59 can strengthen the overall structure).

[0165] When the container 2 is made of a heavier material such as ceramic (such as ceramic cookware), in order to facilitate the picking up and putting down of the container, a positioning block 50 of the same structure can be set above the other side of the side wall, and another set of first screws 51 and nuts 52 can be used to lock and fix a gripping block 60 with a cavity to the positioning block 50 in the same way (reinforcing ribs 59 can also be set in the cavity of the gripping block 60 to strengthen its overall structure), and the first screw 51 is covered with a second cover plate 58 (the second cover plate 58 here has the same function as the second cover plate 58 on the gripping component). At this time, the gripping block 60 will also be suspended on the other side of the side wall, so that it is easier to pick up the container 2 (when picking up the container 2, one hand holds the gripping component and the other hand holds the gripping block 60; in addition, you can also choose to set the same gripping components 64 on both sides of the container 2).

[0166] The principle of the liquid transmission structure of this design is roughly as follows: place the container on the heater, and cover the container with a lid, and then add a certain amount of water to the water tank to stew the ingredients (at this time, the sealing gasket of the one-way valve and the water outlet of the water tank are separated from each other, and water can flow into the water outlet cavity of the valve body). When the ingredients need to be fried or stewed for a certain period of time and water needs to be added, the water can be transported to the output pipe and finally transported into the container by controlling the water pump through the circuit (the action and operating speed of the water pump are controlled by the circuit. The water addition time and water addition amount can be adjusted by circuit control. This part of the circuit is designed by technicians in this field according to needs, and will not be elaborated in this article), and then sprayed out through the nozzle. Since the liquid transmission structure of this design is automatic water addition, it can also be easily operated during appointment and remote control. It only needs to control the water pump action through the circuit and adjust the appropriate parameters.

[0167] When the container is used for baking food, the nozzle can spray water in atomized form to achieve the function of water replenishment; when the container is used for stewing food, the nozzle can spray water directly to achieve the function of fast water addition.

[0168] When the water tank needs to be disassembled for cleaning and maintenance, you only need to pick up the water tank directly. The silicone sealing gasket will automatically block the water outlet under the action of the spring, avoiding water leakage from the outlet.

[0169] The principle of the far-infrared heating structure of this design is roughly as follows: during the heating process of the food, the heater will heat the bottom surface of the food, and the far-infrared heater will heat the top surface of the food (the heater and the far-infrared heater are products in the existing technology, and their corresponding control methods and temperature adjustment methods are all in the existing technology, which will not be elaborated in this article). By heating both sides of the food at the same time, the food can be heated evenly, thereby reducing the occurrence of food that is burnt on one side and uncooked on the other side.

[0170] The reflective cover of the far-infrared heating structure will reflect the heat generated by the far-infrared heater, so that part of the radiation energy that is not absorbed by the food will be reflected back to the surface of the food, thereby improving the energy utilization rate. At this time, the temperature of the reflective cover will also rise accordingly. The heat dissipation chamber set above the cover can promptly accelerate the air circulation speed, thereby cooling the reflective cover.

[0171] By cooperating with the secondary folding arm structure, it can serve as part of the handle to make the structure of the machine more compact; in addition, there is ample space on the outside of the heat dissipation housing for the installation of functional panels.

[0172] The principle of the secondary folding arm structure of this design is roughly as follows: when it is necessary to open the lid, one only needs to hold the anti-scalding component under the second folding arm and lift the second folding arm (equivalent to a handle) to open the lid. At this time, the first folding arm and the second folding arm will rotate, and the lid will form an angle with the container under their action (when no force is applied to the second folding arm, neither the first folding arm nor the second folding arm will rotate. If the size of the angle needs to be adjusted, only force needs to be applied to control the rotation of the second folding arm), so that water droplets on the inner wall of the lid will flow into the container (such as Figure 9 shown).

[0173] The installation process of the combined handle of this design is roughly as follows: first press the handle seat against the side wall of the container so that the edge of the handle seat contacts the side wall (the positioning block is in the first cavity of the handle seat at this time), and then align the positioning hole at the lower end of the handle seat with the circular hole of the positioning block at the lower end of the container side wall, and then use a first screw and nut to lock the two (the nut can be set at the rear end of the positioning block in advance with the help of auxiliary tools. It belongs to the existing technology and will not be described in detail in this article). Then use another set of first screws and nuts to lock the upper end of the handle seat and the positioning block in the same way (due to problems with the production process, there may be a certain deviation in the spacing between the circular holes of the two positioning blocks on the side wall of the container, so the fastening position of the upper end of the handle seat is set to a straight slot, so that it has a certain allowance, so that the handle seat can be combined with the positioning block). After the upper and lower ends of the handle seat are locked, it will be suspended on the side wall of the container (there is no actual connection between the side wall and the handle seat, the handle seat is only locked and fixed to the positioning block). After the handle base is installed, use the second screw to lock the back cover on the handle (the handle base and the handle are integrally formed parts), and finally put the cover plate on the front end of the back cover to cover the second screw.

[0174] Since the gripping part of the container of this design is provided with a first insulating chamber and a second insulating chamber, it can save manufacturing materials while also making the overall air thermal conductivity of the gripping part extremely poor, which is not likely to cause the temperature of the handle to rise, thereby providing good anti-scalding effect.

[0175] like Figure 35 As shown, the control device of the frying and stewing machine in the above embodiment includes an acquisition module, a frying and stewing processing module and a control module, and the acquisition module, the frying and stewing processing module and the control module are electrically connected; the acquisition module is used to retrieve the frying and stewing information of the object to be processed and send a frying and stewing signal, the frying and stewing information includes a preset frying and stewing temperature time-shift curve and a frying and stewing rule, the frying and stewing information is obtained by recording the best cooking effect each time, and stored in the acquisition module for calling; the preset frying and stewing temperature time-shift curve includes a preset far-infrared heater temperature, a preset heater temperature, a preset center temperature of the top surface of the food, a preset temperature of the four corners of the top surface of the food and a collection time point A1; the frying and stewing processing module is used to fry and stew the object to be processed according to the preset frying and stewing temperature time-shift curve and the frying and stewing rule, and collect the actual temperature in real time during the frying and stewing process. The actual temperature information includes the actual far-infrared heater temperature, the actual heater temperature, the actual temperature of the top surface center of the food, the actual temperature of the four corners of the top surface of the food and the collection time point A2; the control module is used to adjust the far-infrared heater temperature and the heater temperature respectively according to the actual temperature information and the preset frying and stewing temperature time-shift curve, so that the difference between the actual temperature of the top surface center of the food, the actual temperature of the four corners of the top surface of the food and the preset temperature of the top surface center of the food, the preset temperature of the four corners of the top surface of the food corresponding to the collection time point in the preset frying and stewing time-shift curve is less than the preset threshold value, and the actual temperature of the top surface center of the food and the actual temperature of the four corners of the top surface of the food tend to be consistent; finally, the heating degree of each position between the top surface and the bottom surface of the food is maximized to be consistent, so that a carbonized layer can be evenly formed at each position on the surface of the food, thereby achieving a better taste.

[0176] The acquisition module includes a function panel, an instruction acquisition unit, an information storage unit and a signal transmitting unit, and the function panel, the instruction acquisition unit, the information storage unit and the signal transmitting unit are electrically connected; after the instruction is input on the function panel, the instruction acquisition unit acquires the instruction and retrieves the frying and stewing information of the relevant object to be processed stored in the information storage unit, and the information storage unit transmits the frying and stewing information to the signal transmitting unit, and the signal transmitting unit sends a matching frying and stewing signal according to the frying and stewing information.

[0177] The frying and stewing processing module includes a signal receiving unit and several sensors. The signal receiving unit, the sensor, the far-infrared heater and the heater are electrically connected. After receiving the frying and stewing signal sent by the signal transmitting unit, the signal receiving unit will control the far-infrared heater and the heater to fry and stew the top and bottom surfaces of the object to be processed respectively, and collect actual temperature information in real time through the sensor.

[0178] The sensor includes several upper sensors and several lower sensors; the upper sensors are electrically connected to the far-infrared heater and are used to detect the temperature data of the top surface of the food and the temperature data of the far-infrared heater; the lower sensors are electrically connected to the heater and are used to detect the temperature data of the bottom surface of the food and the temperature data of the heater.

[0179] The control module is specifically used to, if the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are higher than the preset temperature of the center of the top surface of the food and the preset temperature of the four corners of the top surface of the food, then reduce the actual far-infrared heater temperature and the actual heater temperature according to the preset far-infrared heater temperature and the preset heater temperature; if the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are lower than the preset temperature of the center of the top surface of the food and the preset temperature of the four corners of the top surface of the food, then increase the actual far-infrared heater temperature and the actual heater temperature according to the preset far-infrared heater temperature and the preset heater temperature.

[0180] The actual temperature information collected in real time by the frying and stewing processing module also includes the temperature of the bottom surface of the food; the control module is also specifically used to determine whether the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are close to the temperature of the bottom surface of the food; if the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are close to the temperature of the bottom surface of the food, the heating temperature of the far-infrared heater and the heater at this time is kept unchanged.

[0181] The control device of this embodiment first inputs the relevant instructions of the ingredients on the function panel. After the instruction acquisition unit obtains the instructions, it will retrieve the frying and stewing information of the ingredients stored in the information storage unit (the frying and stewing information includes the preset frying and stewing temperature time-shift curve and frying and stewing rules), and then send out a frying and stewing signal that matches the obtained frying and stewing information; after receiving the frying and stewing signal, the signal receiving unit will control the far-infrared heater and the heater to fry and stew the ingredients according to the frying and stewing rules and the preset frying and stewing temperature time-shift curve, and collect the actual temperature information in real time through the sensor during the frying and stewing process; at the same time, according to the actual temperature information and the preset frying and stewing temperature time-shift curve, the temperature of the ingredients will be controlled by the sensor. The control module adjusts the temperature of the far-infrared heater and the heater temperature respectively (after the sensor collects the data of the actual temperature information, it will feed the data back to the control module. The control module will compare the data with the data in the preset frying and stewing temperature time-shift curve, and determine whether the temperature needs to be adjusted accordingly). When the far-infrared heater and the heater heat the two sides of the ingredients respectively, the actual temperature information can be consistent with the preset temperature information, and finally the heating degree of each position of the ingredients is maximized to be consistent, avoiding the situation where one side is burnt and the other side is uncooked, and a uniform carbonized layer can be produced on the surface, thereby achieving a better taste.

[0182] like Figure 36-Figure 38As shown, the control method of the frying and stewing machine in the above embodiment includes the following steps:

[0183] Step A: obtaining the frying and stewing information of the object to be processed, wherein the frying and stewing information includes a preset frying and stewing temperature time-shift curve and frying and stewing rules.

[0184] During the cooking process, different frying and stewing menus correspond to different frying and stewing information. The object to be processed can be understood as the object to be cooked during cooking. The object to be processed in the method of this embodiment is square tofu (different objects to be processed can be replaced according to needs). The relevant instructions for square tofu are entered in the function panel. After the instruction acquisition unit obtains the instructions, it will retrieve the frying and stewing information of the square tofu stored in the information storage unit (the frying and stewing information may include but is not limited to a preset frying and stewing temperature time-shift curve and frying and stewing rules. The preset frying and stewing temperature time-shift curve includes a preset far-infrared heater temperature, a preset heater temperature, a preset center temperature of the top surface of the food material, a preset temperature of the four corners of the top surface of the food material, and a collection time point A1; the frying and stewing rules can be understood as the rules for frying and stewing, such as the size of the frying and stewing food material, the water consumption for frying and stewing, etc.), and then send a frying and stewing signal that matches the obtained frying and stewing information. As an example, the preset frying and stewing temperature time-shift curve can be obtained by recording the corresponding food top surface center temperature, food top surface four corners temperature, far-infrared heater temperature and heater temperature and frying and stewing rules at each time point when the chef achieves the best cooking effect for each frying and stewing menu, so as to obtain the preset food top surface center temperature, food top surface four corners temperature, preset far-infrared heater temperature, preset heater temperature and collection time point A1 in the preset frying and stewing temperature time-shift curve, and store the data in the information storage unit, waiting for call.

[0185] Step B, frying and stewing the object to be processed according to the frying and stewing information, and collecting actual temperature information in real time during the frying and stewing process; the actual temperature information includes the actual far-infrared heater temperature, the actual heater temperature, the actual center temperature of the top surface of the food, the actual temperature of the four corners of the top surface of the food and the collection time point A2.

[0186] After receiving the frying and stewing signal, the signal receiving unit will control the far-infrared heater and the heater to fry and stew the top and bottom surfaces of the square tofu respectively, and collect the actual temperature information in real time through the sensor.

[0187] Step C, according to the actual temperature information and the preset frying and stewing temperature time-shift curve, respectively adjust the temperature of the far-infrared heater and the heater temperature, so that the difference between the actual temperature of the center of the top surface of the food, the actual temperature of the four corners of the top surface of the food and the preset temperature of the center of the top surface of the food, the preset temperature of the four corners of the top surface of the food corresponding to the time point collected in the preset frying and stewing time-shift curve is less than the preset threshold, and the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food tend to be consistent; ultimately, the heating degree of each position of the square tofu is maximized to be consistent, so that a carbonized layer can be evenly formed at each position on the surface of the square tofu, thereby achieving a better taste.

[0188] After the sensor collects the actual temperature information data, it will feed the data back to the control module. The control module will compare the data with the data in the preset frying and stewing temperature time-shift curve and determine whether the temperature needs to be adjusted accordingly. The adjustment includes:

[0189] If the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are higher than the preset temperature of the center of the top surface of the food and the preset temperature of the four corners of the top surface of the food, the actual temperature of the far-infrared heater and the actual temperature of the heater are reduced according to the preset far-infrared heater temperature and the preset heater temperature;

[0190] If the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are lower than the preset temperature of the center of the top surface of the food and the preset temperature of the four corners of the top surface of the food, the actual far-infrared heater temperature and the actual heater temperature will be increased according to the preset far-infrared heater temperature and the preset heater temperature.

[0191] Step D: Real-time collection of the temperature of the bottom surface of the food (the temperature of the bottom surface of the food is also one of the data in the actual temperature information collected by the sensor), and determining whether the actual temperature of the center of the top surface of the food and the actual temperatures of the four corners of the top surface of the food are close to the temperature of the bottom surface of the food;

[0192] Since the square tofu is placed on a container for frying and stewing, the temperature of the bottom surface of the food will be close to the temperature of the bottom inner wall of the container. If the actual temperature of the center of the top surface of the food and the actual temperature of the four corners of the top surface of the food are close to the temperature of the bottom surface of the food, the control module will keep the heating temperature of the far-infrared heater and the heater unchanged at this time, so that all parts of the square tofu can be heated evenly, avoiding the situation where one side is burnt and the other side is not cooked, and a uniform carbonized layer can be produced on the surface, making the square tofu taste better.

[0193] The data in Table 1 were obtained after testing the top surface of the square tofu during the frying and stewing process. It can be seen from Table 1 that after adjusting the temperature of the far-infrared heater and the heater according to the preset frying and stewing temperature time-shift curve, the temperature at the center of the top surface of the actual food and the temperature at the center of the four corners of the actual food can be close to the same.
