Description

TECHNICAL FIELD

[0001] The utility model relates to a cooking machine technical field, concretely relates to a cooking machine convenient for conveying sauce. BACKGROUND

[0002] There are many Chinese cuisines, and the types and amounts of seasonings of each cuisine are different. Meanwhile, the same chef also has differences in the amount of seasonings for the same dish, and there may be a situation of putting less seasoning in the actual cooking process. The differences in seasoning types, amounts, placement order, and placement time will result in different tastes of dishes.

[0003] The automatic cooking machine is an intelligent cooking device controlled by a microcomputer. After setting the menu program, it can automatically add various seasonings according to the feeding order and time, automatically stir-fry, and automatically control the fire, so as to realize the automation and standardization of the cooking process, thereby keeping the taste of the dishes uniform.

[0004] Sauce is an essential paste seasoning in cooking. Commonly used sauces include chopped pepper sauce, tomato sauce, bean paste, and soybean sauce. Due to the high viscosity and poor flowability of sauce, the existing cooking machines generally use a suction and extrusion method to add sauce, for example, a cooking machine disclosed in the authorized announcement No. CN211883394U, which sets a three-way control valve at the discharge port of the sauce tank, sets a flow guide pipe communicating with the discharge port at the front end of the three-way control valve, and sets a pneumatic sauce pump at the rear end of the three-way control valve. By controlling the operation of the pneumatic sauce pump, a predetermined amount of sauce is pumped from the sauce tank into the pneumatic sauce pump, then the discharge port of the sauce tank is closed and the feed port of the flow guide pipe is opened, and the sauce is extruded from the flow guide pipe by the pneumatic sauce pump. However, during the addition of sauce, due to the high viscosity of the sauce, a part of the sauce will adhere to the discharge port of the flow guide pipe when it is discharged from the discharge port of the flow guide pipe, which is not easy to completely discharge from the discharge port of the flow guide pipe, resulting in accumulation of the sauce, which is prone to cause inaccurate output of the sauce.

DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the technical scheme of the embodiments of the present application, the following will briefly introduce the drawings needed to be used in the embodiments. Obviously, the drawings described in the following are some embodiments of the present application, and for those skilled in the art, other drawings can also be obtained without creative labor on the basis of these drawings.

[0028] Please refer to Figures 1 to 3 The embodiment of the present application provides a stir-fry machine convenient for conveying sauce, which comprises a stir-fry machine body 10 and a sauce conveying device 20 arranged on the stir-fry machine body 10. The sauce conveying device 20 comprises a sauce storage tank 21, a sauce quantitative conveying mechanism 22 and an auxiliary discharging mechanism 23. The sauce storage tank 21 is used to fill the sauce required for stir-frying. The discharge port of the sauce storage tank 21 is connected with the feeding port of the sauce quantitative conveying mechanism 22. The discharge port of the sauce quantitative conveying mechanism 22 is connected with the feeding port of the auxiliary discharging mechanism 23. The discharging port 235 of the auxiliary discharging mechanism 23 is opposite to the stir-fry pot 11 of the stir-fry machine body 10. When the stir-fry machine is used for stir-frying, the sauce in the sauce storage tank 21 can be quantitatively conveyed to the auxiliary discharging mechanism 23 through the sauce quantitative conveying mechanism 22. The sauce quantitatively output by the sauce quantitative conveying mechanism 22 can be discharged into the stir-fry pot 11 through the auxiliary discharging mechanism 23. After the sauce is discharged into the stir-fry pot 11 by the auxiliary discharging mechanism 23, the discharging port 235 can be blocked to prevent the outside air from entering the auxiliary discharging mechanism 23 from the discharging port 235, so that the accumulation of the sauce at the discharging port 235 is avoided, the amount of the sauce quantitatively output by the sauce quantitative conveying mechanism 22 is ensured to be sufficient, and the phenomenon that the sauce is dried and solidified at the discharging port 235 is also avoided.

[0029] Specifically, please refer to Figures 3 to 5The sauce quantitative conveying mechanism 22 comprises a three-way valve 221, a first reciprocating pushing device 222, a cylinder barrel 223 and a piston 224 matched with the cylinder barrel 223. The lower end of the sauce storage tank 21 is provided with a discharge port. The discharge port of the sauce storage tank 21 is connected with the feeding port of the three-way valve 221. One end of the cylinder barrel 223 is connected with the first discharge port of the three-way valve 221. The feeding port of the auxiliary discharging mechanism 23 is connected with the second discharge port of the three-way valve 221. The three-way valve 221 is switched to open the direction so as to make the feeding port of the three-way valve 221 communicate with the first discharge port or make the first discharge port of the three-way valve 221 communicate with the second discharge port. The piston 224 is installed in the cylinder barrel 223 and is in airtight cooperation with the cylinder barrel 223. The first reciprocating pushing device 222 is installed at the other end of the cylinder barrel 223. The telescopic arm of the first reciprocating pushing device 222 is connected with the piston 224 installed in the cylinder barrel 223. The first reciprocating pushing device 222 is an electric push rod which is powered by an external power supply. The piston 224 is driven by the first reciprocating pushing device 222 to reciprocate in the cylinder barrel 223 along the axial direction of the cylinder barrel 223. When the piston 224 is driven by the first reciprocating pushing device 222 to reciprocate, the three-way valve 221 needs to be used in cooperation. When the three-way valve 221 is opened to make the feeding port thereof communicate with the first discharge port, the telescopic arm of the first reciprocating pushing device 222 is retracted to drive the piston 224 to move away from the one end of the cylinder barrel 223 which is far away from the three-way valve 221. The sauce storage tank 21 is negatively pumped by the piston 224 to suck the sauce in the sauce storage tank 21 into the cylinder barrel 223. When the three-way valve 221 is opened to make the first discharge port thereof communicate with the second discharge port, the telescopic arm of the first reciprocating pushing device 222 is extended to drive the piston 224 to move toward the one end of the cylinder barrel 223 which is close to the three-way valve 221. The sauce sucked into the cylinder barrel 223 is pushed from the second discharge port of the three-way valve 221 to the auxiliary discharging mechanism 23, and the sauce is extruded from the discharge port 235 of the auxiliary discharging mechanism 23 into the cooking pot 11. When the first reciprocating pushing device 222 pushes the sauce to the auxiliary discharging mechanism 23, the amount of the output sauce is controlled by controlling the stroke of the piston 224 driven by the first reciprocating pushing device 222 to move toward the one end of the cylinder barrel 223 which is close to the three-way valve 221.

[0030] Please refer to Figure 4 、 Figures 7 to 9The auxiliary discharging mechanism 23 comprises a second reciprocating pushing device 231, a discharging cylinder 232 and a piston column 233 matched with the discharging cylinder 232. The discharging cylinder 232 is arranged above the wok 11 of the cooking machine body 10. One end of the discharging cylinder 232 is the discharging port 235 mentioned above, which is directed to the wok 11 of the cooking machine body 10. The discharging port 235 is in an open state. The second reciprocating pushing device 231 is arranged at the other end of the discharging cylinder 232. A branch pipe 234 which is in communication with the inner cavity of the discharging cylinder 232 is arranged on the outer side wall of the discharging cylinder 232 between the second reciprocating pushing device 231 and the discharging port 235. The branch pipe 234 is in communication with the second discharging port of the three-way valve 221 through the conduit 225. After the sauce is discharged from the second discharging port of the three-way valve 221, it can enter the discharging cylinder 232 through the conduit 225 and the branch pipe 234 and be discharged into the wok 11 from the discharging port 235. The piston column 233 is inserted into the discharging cylinder 232 and connected with the telescopic arm of the second reciprocating pushing device 231, so that the piston column 233 is driven to reciprocate in the discharging cylinder 232 by the second reciprocating pushing device 231. The second reciprocating pushing device 231 is an electric push rod which is powered by an external power supply. The piston column 233 is a long column. The diameter of the piston column 233 matches the inner diameter of the discharging cylinder 232. When the piston column 233 is retracted in the discharging cylinder 232, the communication between the discharging cylinder 232 and the branch pipe 234 is opened, so that the sauce can enter the discharging cylinder 232. When the piston column 233 extends to the discharging port 235 in the discharging cylinder 232, the end of the piston column 233 directed to the discharging port 235 can be flush with the discharging port 235 to block the discharging port 235. At the same time, the side wall of the piston column 233 can block the communication between the discharging cylinder 232 and the branch pipe 234 to prevent the sauce from entering the discharging cylinder 232.When the sauce is output to the frying pot 11, the second reciprocating pushing device 231 is first controlled to drive the piston column 233 to retract towards the end of the discharge cylinder 232 away from the discharge port 235, so that the communication between the discharge cylinder 232 and the branch pipe 234 is opened, and then the first reciprocating pushing device 222 is controlled to push the sauce into the discharge cylinder 232, so that the sauce pushed by the first reciprocating pushing device 222 can enter the discharge cylinder 232 from the branch pipe 234 and flow out of the discharge port 235 of the discharge cylinder 232 into the frying pot 11. When the first reciprocating pushing device 222 completes the sauce pushing action, the second reciprocating pushing device 231 drives the piston column 233 to move towards the discharge port 235 of the discharge cylinder 232, so that all the sauce in the discharge cylinder 232 is squeezed out of the discharge port 235, and the communication between the discharge cylinder 232 and the branch pipe 234 and the discharge port 235 are sealed to prevent external air from entering the discharge cylinder 232 from the discharge port 235. In this way, the accumulation of sauce in the discharge port 235 can be avoided, the quantitative sauce output mechanism 22 can ensure that the sauce is output into the frying pot 11 each time, the error of the sauce output amount is reduced, the sauce is prevented from drying out at the discharge port 235, and the sauce is prevented from deteriorating when not discharged for a long time.

[0031] Please refer to Figure 7 In order to ensure the airtightness between the piston column 233 and the discharge cylinder 232, a first sealing ring 236 is annularly nested on the end of the piston column 233 towards the discharge port 235 of the discharge cylinder 232. The first sealing ring 236 is in contact with the inner wall of the discharge cylinder 232 to seal the gap between the piston column 233 and the discharge cylinder 232. The first sealing ring 236 moves with the piston column 233 during reciprocating movement of the piston column 233. A second sealing ring is annularly nested in the discharge cylinder 232. The second sealing ring is located on the side of the branch pipe 234 away from the discharge port 235. The second sealing ring is fixedly arranged. The piston column 233 passes through the second sealing ring to move reciprocally. The second sealing ring can seal the end of the discharge cylinder 232 where the second reciprocating pushing device 231 is installed, so as to prevent the sauce from leaking.

[0032] Please continue to refer to Figure 7 Further, the end of the piston column 233 towards the discharge port 235 is provided with a non-stick coating 237, and the discharge port 235 of the discharge cylinder 232 is also provided with a non-stick coating 237. The non-stick coating 237 is made of polytetrafluoroethylene or ceramic coating, which can reduce the adhesion of the sauce to the end of the piston column 233 and the discharge port 235.

[0033] In a preferred embodiment, the first reciprocating pushing device 222 and the second reciprocating pushing device 231 described above can also be replaced by telescopic oil cylinders or air cylinders, which have the same functions.

[0034] Please refer toFigure 3 and Figure 6 Furthermore, the outlet of the sauce storage tank 21 is located at the bottom of the sauce storage tank 21. Since the sauce is relatively viscous, when the amount of sauce in the sauce storage tank 21 decreases, it is easy to accumulate or block it in the sauce storage tank 21, causing poor discharge. By setting a stirring motor 32 at the center of the outer bottom of the sauce storage tank 21, the shaft of the stirring motor 32 is inserted longitudinally into the sauce storage tank 21. A stirring blade 31 is set in the sauce storage tank 21. The stirring blade 31 is installed on the shaft of the stirring motor 32 that is inserted into the sauce storage tank 21 and is close to the bottom of the sauce storage tank 21. The stirring motor 32 drives the stirring blade 31 to rotate in the sauce storage tank 21. The stirring blade 31 is used to push the sauce in the sauce storage tank 21 into the outlet to assist in discharge.

[0035] The sauce conveying device 20 on this easy-to-convey cooking machine can be set in multiple groups according to usage needs, each used to convey different flavors or types of sauces.

[0036] The cooking machine, designed for easy sauce delivery, is equipped with a quantitative controller 40 that controls the output of sauces and other seasonings. The quantitative controller 40 is a microcircuit controller, which sets the output quantity and time of the sauce. The control terminals of the first reciprocating pusher 222 and the second reciprocating pusher 231 of the sauce delivery device 20, as well as the three-way valve 221, are electrically connected to the quantitative controller 40. The three-way valve 221 is a three-way solenoid valve. The quantitative controller 40 controls the activation of the first reciprocating pusher 222, the second reciprocating pusher 231, and the three-way valve 221. The quantitative controller 40 controls the pushing stroke of the first reciprocating pusher 222, thereby controlling the output quantity of the sauce.

[0037] When this sauce-conveying stir-fry machine is initially used, the quantitative controller 40 controls the second reciprocating pushing device 231 to retract, opening the discharge port 235 of the discharge cylinder 232 and opening the connection between the discharge cylinder 232 and the branch pipe 234. Then, the first reciprocating pushing device 222 is controlled to perform reciprocating suction discharge. During the reciprocating suction operation of the first reciprocating pushing device 222, the quantitative controller 40 controls the three-way valve 221 to switch its opening direction. The three-way valve 221 and the first reciprocating pushing device... The first reciprocating pusher 222 works in conjunction with the second reciprocating pusher 231 to discharge the sauce from the sauce storage tank 21 to the discharge cylinder 232. Once the sauce flows out of the discharge port 235 of the discharge cylinder 232, the first reciprocating pusher 222 stops operating, and the second reciprocating pusher 231 extends to clear the sauce from the discharge cylinder 232 and seal the connection between the discharge cylinder 232 and the branch pipe 234, as well as the discharge port 235 of the discharge cylinder 232. At this point, the branch pipe 234 and the conduit 225 are already buffered with sauce, and preparation is complete. Thus, during the actual cooking operation, the quantitative controller 40 controls the first reciprocating pusher 222, the second reciprocating pusher 231, and the three-way valve 221 to start according to a set time, thus quantitatively distributing the sauce.

[0038] When sauce needs to be dispensed, the metering controller 40 first controls the second reciprocating pushing device 231 to drive the piston 233 to retract towards the end of the discharge cylinder 232 away from the discharge port 235, thus opening the connection between the discharge cylinder 232 and the branch pipe 234. Then, it controls the first reciprocating pushing device 222 to push the sauce according to the set stroke, so that the sauce enters the discharge cylinder 232 from the conduit 225 and the branch pipe 234, and flows out from the discharge port 235 of the discharge cylinder 232 into the wok 11. After the first reciprocating pushing device 222 completes the sauce conveying action, the metering controller 40 controls the second reciprocating pushing device 231 to drive the piston 233 to extend towards the discharge port 235 of the discharge cylinder 232, squeezing all the sauce that has entered the discharge cylinder 232 out to the discharge port 235. 5. The discharge port 235 of the discharge cylinder 232 is sealed, and the quantitative conveying operation of the sauce is completed. When the sauce needs to be conveyed again, the first reciprocating pusher 222 and the second reciprocating pusher 231 are controlled by the quantitative controller 40 to repeat the above action. The cooking machine that facilitates the conveying of sauce works with the piston column 233 and the discharge cylinder 232 to avoid the accumulation of sauce in the discharge port 235. This ensures that the sauce output by the quantitative conveying mechanism 22 can be discharged into the cooking pot 11 each time, reducing the error of the sauce output. In addition, it prevents outside air from entering the discharge cylinder 232 from the discharge port 235, preventing the sauce from drying at the discharge port 235 and preventing the sauce from deteriorating when it is not discharged for a long time.

[0039] This cooking machine, designed for easy sauce delivery, is also equipped with other storage and conveying mechanisms for storing different seasonings, such as oil, salt, soy sauce, and vinegar. These storage and conveying mechanisms are electrically connected to a quantitative controller 40, which is programmed with predetermined dispensing times, order of dispensing, and time intervals for each seasoning. When a particular seasoning is needed, the quantitative controller 40 activates the storage and conveying mechanism to dispense the corresponding seasoning.
