Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Generally, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0033] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0034] Embodiment 1

[0035] Please refer to Figure 1 , this embodiment provides an automatic oil - adding cooking machine. There is a recipe program in the cooking device, and the corresponding automatic operation program in the recipe program can be selected according to different cooking methods and cooking ingredients to complete the cooking of the ingredients. Among them, during the cooking process, many dishes and cooking methods require the use of cooking oil for making. For example, in cooking methods such as frying, stir - frying, and even boiling, oil needs to be added to the ingredients in the pot. Therefore, oil addition is an important link in the recipe program.

[0036] The automatic oil - adding cooking machine of this embodiment includes a stirring container 100 with a stirring component arranged inside, a heating device 200 arranged on the side wall of the stirring container 100, a temperature sensor arranged inside the stirring container 100, and an oil - adding device arranged on the stirring container 100. The oil - adding device includes an oil tank 301 for accommodating edible oil, a pressure pump 302 communicated with the oil tank 301, and a weight sensor 305 arranged at the bottom of the oil tank 301. The oil tank 301 is communicated with the stirring container 100 through an oil pipe 303;

[0037] It further includes a first timer, a second timer, and a controller electrically connected to the first timer and the second timer. The controller is also electrically connected to the recipe controller in the recipe program, the temperature sensor, the weight sensor 305, and the pressure pump 302 respectively. The operation procedure of the preset recipe is in the recipe controller. The first timer starts timing when started by the operation procedure of the recipe. The controller receives the oil - adding program instruction from the recipe controller, reads the duration of the start of the recipe operation procedure recorded by the first timer, that is, the duration from the start of the recipe program to the controller receiving the oil - adding instruction recorded by the first timer. The controller is used to control the pressure pump 302 to pressurize according to the start duration and the temperature signal of the temperature sensor so that the edible oil in the oil tank 301 flows into the stirring container 100; The controller also receives the weight signal of the oil tank 301 detected by the weight sensor 305. The second timer starts timing when the pressure pump 302 starts to pressurize, that is, the second timer records the oil - adding duration from the start of the pressure pump 302 to the oil tank 301 reaching the preset weight. The controller controls the pressure pump 302 to stop pressurizing according to the oil - adding duration and the weight signal.

[0038] It should be noted that, first, the stirring container 100 is used to accommodate ingredients, edible oil, etc., which is equivalent to the "pot" in our daily cooking; the stirring component inside the stirring container 100 is used for stirring to fully mix the ingredients, etc. inside the stirring container 100.

[0039] Second, the heating device 200 is used to heat the stirring container 100. Specifically, the heating device 200 can be arranged at the bottom of the stirring container 100. After starting the recipe program of the automatic oil - adding cooking machine, the heating device 200 can start heating to pre - heat the stirring container 100 first. After the temperature inside the stirring container 100 reaches the requirement, then start adding oil. The temperature sensor arranged inside the stirring container 100 detects the real - time temperature inside the stirring container 100.

[0040] On the other hand, some cooking methods do not require cooking oil, but still need the heating device 200 to heat the stirring container 100 to cook the ingredients in the stirring container 100, such as the method of boiling in clear water. Therefore, when the recipe program of the automatic oil-adding cooking machine is started, the heating device 200 can start heating. Generally, the heating device 200 can be controlled by the recipe controller in the recipe program. The control of the heating device 200 does not belong to the part of this embodiment and will not be specifically described here.

[0041] Third, the oil-adding device includes an oil tank 301, a pressure pump 302, a weight sensor 305, and an oil pipe 303. Among them, the oil tank 301 contains cooking oil, and the pressure pump 302 communicated with the oil tank 301 is used to pressurize the oil tank 301 so that the oil in the oil tank 301 flows into the stirring container 100 through the oil pipe 303. The weight sensor 305 at the bottom of the oil tank 301 is used to detect the weight of the oil tank 301, that is, to detect the weight of the oil in the oil tank 301.

[0042] Among them, the pressure pump 302 can be an air pump. As the pressure pump 302, the air pump is clean. If an oil pump is used, the cleanliness and food contact requirements of the oil pump are very high, resulting in a very high cost of the oil pump and forming an invisible waste of resources. When directly used to pump oil, in the long-term operation, the high-viscosity oil film and oil scale formed by the oil residue will reduce the performance and service life of the oil pump. Using an air pump can avoid the above problems of the oil pump.

[0043] In addition, the oil pipe 303 communicates with the stirring container 100 and the oil tank 301. The oil pipe 303 can communicate with the stirring container 100 from the side wall of the stirring container 100, or can also communicate with the stirring container 100 from the bottom wall or the top of the stirring container 100. The communication path of the oil pipe 303 from the oil tank 301 to the stirring container 100 is not specifically limited here, as long as the oil can be introduced from the oil tank 301 into the stirring container 100.

[0044] Fourth, oil-adding instruction: The recipe controller in the recipe program sends an oil-adding instruction to the controller. After receiving the oil-adding instruction, the controller judges the oil-adding timing.

[0045] The operation procedure of the preset recipe is in the recipe controller, and oil-adding is one of the links in the operation procedure of the preset recipe. Judge the oil-adding timing: Judge whether the real-time temperature in the stirring container 100 is within the preset temperature threshold range through the temperature sensor. If the real-time temperature is within the preset temperature threshold range, it means that the preheating of the stirring container 100 meets the requirements, and oil can be added to the stirring container 100.

[0046] In addition, the first timer is started by the operation program of the recipe for timing. The first timer is used to record the duration from the start of the recipe program to the controller receiving the fueling instruction, and is also used to judge the fueling timing, that is, whether the execution time period of the fueling step in the recipe program meets the requirements. If it meets the requirements and the start duration is within the preset duration threshold range, fuel can be added to the mixing container 100.

[0047] It should be noted that generally, when judging the fueling timing, if both the real-time temperature and the start duration meet the requirements, fuel can be added to the mixing container 100.

[0048] Fifth, the second timer records the fueling duration from the start of the pressure pump 302 to the fuel tank 301 reaching the preset weight. What the second timer records is the fueling duration required from the start of fueling until the required amount of fuel is added, and it is judged whether this time is within the required range. At the same time, the start of the pressure pump 302 indicates the start of fueling, and the fuel tank 301 reaching the preset weight indicates that the fueling amount of the fuel flowing from the fuel tank 301 into the mixing container 100 meets the requirements. The amount of fuel in the fuel tank 301 is judged by the weight sensor 305, and the fueling amount in the mixing container 100 can be judged by judging the amount of fuel in the fuel tank 301. If both the fueling duration and the fueling amount meet the requirements, it means that the fueling action meets the requirements, then the fueling is stopped and subsequent actions are carried out.

[0049] Sixth, the controller is electrically connected to the first timer, the second timer, the temperature sensor, the weight sensor 305 and the pressure pump 302 respectively to control the above-mentioned devices.

[0050] Specifically, the working principle of this automatic fueling cooking machine is as follows: This automatic fueling cooking machine automatically executes the recipe program. When it runs to the fueling step of the recipe program, the recipe controller sends a fueling instruction to the controller. After receiving the fueling instruction, the controller first judges the fueling time: the controller compares the start duration recorded by the first timer with the preset duration, and at the same time the controller compares the real-time temperature measured by the temperature sensor with the preset temperature. When both meet the requirements, the fueling action is executed. The controller controls the pressure pump 302 to pressurize so that the edible oil in the fuel tank 301 flows into the mixing container 100 to start fueling. Then the fueling amount is judged: the controller receives the weight signal of the fuel tank 301 detected by the weight sensor 305 and the fueling duration recorded by the second timer, and compares them with their respective thresholds. When both the fueling amount and the fueling duration meet the requirements, the fueling is completed, and the controller controls the pressure pump 302 to stop working.

[0051] The automatic oil - adding cooking machine provided by the embodiment of the present invention stirs with a stirring component in the stirring container 100, heats the stirring container 100 with a heating device 200, a fuel pipe 303 connects the fuel tank 301 and the stirring container 100, and the oil in the fuel tank 301 is pumped into the stirring container 100 through a pressure pump 302. A temperature sensor is provided in the stirring container 100, and a weight sensor 305 is provided at the bottom of the fuel tank 301. The controller is electrically connected to the recipe controller in the recipe program, receives the oil - adding instruction sent by the recipe controller, and a first timer records the duration from the start of the recipe program to the controller receiving the oil - adding instruction. The controller is used to select the oil - adding time according to the start duration and the temperature signal of the temperature sensor, and control the pressure pump 302 to pressurize so that the edible oil in the fuel tank 301 flows into the stirring container 100. During oil - adding, a second timer records the oil - adding duration from the start of the pressure pump 302 to the fuel tank 301 reaching the preset weight. The controller determines the oil - adding amount according to the oil - adding duration and the weight signal, and when the oil - adding amount is reached, the controller controls the pressure pump 302 to stop pressurizing. In this way, the oil - adding time point can be accurately controlled, the best time for oil - adding can be selected, and the oil - adding amount can be accurately controlled to achieve automatic oil - adding.

[0052] Further, as Figure 2 shown, it further includes a housing 400. The heating device 200 and the oil - adding device are both arranged inside the housing 400, and the stirring container 100 is arranged outside the housing 400; the stirring container 100 includes a container body and a container cover 101. One end of the container body is open and hollow inside, the container cover 101 is covered on the opening of the container body, and the container cover 101 and the housing 400 are detachably connected by a hinge.

[0053] The container cover 101 is detachable, which is convenient for cleaning. At the same time, the heating device 200 and the oil - adding device are both arranged inside the housing 400. Inside the housing 400, it can make the automatic oil - adding cooking machine beautiful and clean, and avoid the heating device 200 and the oil - adding device being affected by oil stains and reducing their service performance.

[0054] The weight sensor 305 is of course also arranged inside the housing 400. There is an operation interface outside the housing 400. There are control buttons 404 on the operation interface, and the control buttons 404 are electrically connected to the controller for operation. At the same time, a display screen 403 is also provided on the operation interface, which can be used to display the real - time temperature in the stirring container 100, the real - time weight of the fuel tank 301, the start duration recorded by the first timer, and the oil - adding duration recorded by the second timer, facilitating personnel to view.

[0055] Exemplarily, as Figure 3 shown, the two ends of the fuel pipe 303 are respectively formed with an oil inlet communicating with the fuel tank 301 and an oil outlet communicating with the stirring container 100. The oil outlet is connected with an oil injector 306, and the oil injector 306 is arranged on the hinge.

[0056] The fuel injector 306 is provided on the hinge. The oil outlet of the oil pipe 303 is connected to the fuel injector 306, and the oil outlet is connected to the stirring container 100. In this way, the oil flowing out of the fuel tank 301 passes through the oil pipe 303 and then through the fuel injector 306, and is sprayed into the stirring container 100 to complete refueling.

[0057] Fixing the fuel injector 306 on the hinge means fixing the fuel injector 306 on the automatic fueling cooking machine. The oil pipe 303 and the fuel injector 306 are fixedly connected and sealed, so that the fuel injector 306 and the oil pipe 303 cannot be easily disassembled, avoiding water remaining in the fuel injector 306 and the oil pipe 303 when scrubbing the automatic fueling cooking machine, which may cause the oil in the heating stirring container 100 to splash and scald people.

[0058] Exemplarily, the oil pipe 303 passes through the container cover 101 to connect the fuel tank 301 and the container body. The oil pipe 303 includes a first oil pipe located inside the machine housing 400 and a second oil pipe 303A located inside the container cover 101, and the first oil pipe and the second oil pipe 303A are connected.

[0059] The first oil pipe inside the machine housing 400 further includes an oil pipe 303C located inside the fuel tank and an oil pipe 303B outside the fuel tank. Here, an example is given where the oil pipe 303 passes through the container cover 101 and then connects to the stirring container 100.

[0060] When the container cover 101 and the machine housing 400 are hinged, the container cover 101 can be opened as shown in Figure 4 and Figure 5 . The second oil pipe 303A is accommodated inside the container cover 101, and the first oil pipe and the second oil pipe 303A are connected. Depending on the installation position and shape of the container cover 101 and the machine housing 400, the docking positions of the interface K1 of the second oil pipe 303A and the interface K2 of the first oil pipe are different.

[0061] As shown in Figure 6 , the buckle 1011 on the container cover 101 can be snapped into the slot 405 on the machine housing 400, so that the container cover 101 and the machine housing 400 can also be screwed together. The second oil pipe 303A is accommodated inside the container cover 101, and the first oil pipe and the second oil pipe 303A are connected.

[0062] When the shapes of the mating parts of the container cover 101 and the machine housing 400 are different, as shown in Figure 7 and Figure 8 , the docking positions of the interface K1 of the second oil pipe 303A and the interface K2 of the first oil pipe are different. The second oil pipe 303A accommodated inside the container cover 101 only has half of the structure shown in Figure 5 , and the first oil pipe is deformed into a bent structure. The first oil pipe and the second oil pipe 303A are connected, still realizing the introduction of the oil in the fuel tank 301 into the stirring container 100.

[0063] In addition, the pressure pump 302 and the fuel tank 301 are also connected through the pump oil pipe 304. The shape and position of the pump oil pipe 304 are set according to specific requirements and will not be elaborated here.

[0064] Furthermore, the stirring assembly includes a motor 401 and a stirring blade 102 connected to the motor 401. The motor 401 and the stirring blade 102 are drivingly connected through a belt mechanism 402.

[0065] The belt mechanism 402 includes two belt pulleys and a belt. The output shaft of the motor 401 and the rotating shaft of the stirring blade 102 are respectively drivingly connected to a belt pulley, and the two belt pulleys are drivingly connected through the belt, so that the motor 401 drives the stirring blade 102 to rotate to complete the stirring. The belt pulley drive structure is simple and the operation is stable.

[0066] Embodiment 2

[0067] As Figure 9 and Figure 10 shown, this embodiment provides a control method for an automatic oil-feeding cooking machine, which applies the automatic oil-feeding cooking machine of the above embodiment. The method includes:

[0068] S100: Receive the start signal of the recipe controller, and instruct the first timer to start timing.

[0069] The controller receives the start signal of the recipe controller and at the same time instructs the first timer to start timing.

[0070] S110: Receive the oil-feeding instruction of the recipe controller, read the start duration recorded by the first timer, and obtain the temperature signal detected by the temperature sensor.

[0071] The controller is electrically connected to the recipe controller. The recipe controller is the overall control of the recipe program. When the recipe program executes to the oil-feeding step, the recipe controller sends an oil-feeding instruction to the controller. After receiving the oil-feeding instruction, the controller is ready to start oil-feeding. At the same time, read the start duration recorded by the first timer at this time and obtain the temperature signal detected by the temperature sensor.

[0072] S120: The start duration reaches the preset duration, and the temperature signal reaches the preset temperature.

[0073] In the recipe program, there are other steps before oil-feeding. When the oil-feeding step is started, it is necessary to judge whether the actual oil-feeding step conforms to the start time of the corresponding oil-feeding step in the whole recipe program in the recipe program. And step S120 is to judge the oil-feeding timing. The start duration fed back by the first timer is the duration from the start of the recipe program to the controller receiving the oil-feeding instruction. Judge whether the execution time period of the oil-feeding step in the recipe program represented by the start duration reaches the preset duration. If it is satisfied, oil can be added to the stirring container 100.

[0074] Meanwhile, it is also necessary to determine whether the real-time temperature in the stirring container 100 reaches the preset temperature through the temperature sensor. If it reaches, it means that the preheating of the stirring container 100 meets the requirements, and oil can be added to the stirring container 100.

[0075] S130: Control the pressure pump 302 to start pressurizing and instruct the second timer to start timing.

[0076] When the startup duration reaches the preset duration and the temperature signal reaches the preset temperature, control the pressure pump 302 to start. The pressure pump 302 pressurizes the fuel tank 301 so that the oil in the fuel tank 301 is added to the stirring container 100. Meanwhile, the controller controls the second timer to start timing and records the initial refueling time.

[0077] On the other hand, when the startup duration reaches the preset duration but the temperature signal does not reach the preset temperature, extend the time for reading the startup duration, that is, extend the startup duration. After the extension, when the temperature signal reaches the preset temperature, refueling is possible, and control the pressure pump 302 to start;

[0078] If the temperature signal does not reach the preset temperature after the extension, the controller sends an alarm signal.

[0079] In addition, there is another situation. When the startup duration does not reach the preset duration but the temperature signal reaches the preset temperature, the refueling operation will not be immediately executed. At this time, the controller sends an alarm signal. This alarm signal is to send an instruction to the recipe controller, and the recipe controller controls to turn off the heating device 200 or reduce the heating temperature of the heating device 200 to reduce the real-time temperature in the stirring container 100 so that after the startup duration and the real-time temperature match, the refueling operation is carried out.

[0080] S140: Receive the weight signal detected by the weight sensor 305. When the weight signal reaches the preset threshold, obtain the refueling duration recorded by the second timer.

[0081] Receive the weight signal detected by the weight sensor 305 and the refueling duration signal recorded by the second timer respectively, and compare the real-time weight of the fuel tank 301 with the preset weight;

[0082] What the second timer records is the refueling duration from the start of refueling until the required amount of oil is refueled. When the pressure pump 302 starts to refuel, the fuel tank 301 reaching the preset weight means that the refueling amount of the oil flowing from the fuel tank 301 into the stirring container 100 meets the requirements. The amount of oil in the fuel tank 301 is judged through the weight sensor 305, so as to judge the refueling amount added to the stirring container 100.

[0083] S150: When the refueling duration is within the preset refueling duration threshold range, control the pressure pump 302 to stop pressurizing.

[0084] When the real-time weight is within the preset weight threshold range and the refueling duration is within the preset refueling duration threshold range, it indicates that refueling is completed. At this time, the controller controls the pressure pump 302 to stop working, and then the fuel tank 301 stops refueling the mixing container 100.

[0085] On the other hand, when the real-time weight and the refueling duration do not meet the requirements, there are two cases:

[0086] When the refueling duration is less than the lower limit of the preset refueling duration threshold, but the real-time weight of the fuel tank 301 is within the preset weight threshold range, it indicates that the fuel tank 301 may leak and cause oil leakage. Then the controller sends an alarm signal for personnel to repair.

[0087] When the refueling duration is greater than the upper limit of the preset refueling duration threshold, but the real-time weight of the fuel tank 301 is less than the lower limit of the preset weight threshold, it indicates that the oil pipe 303 may be blocked. The controller sends an alarm signal for personnel to repair.

[0088] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
