Description

Technical Field

[0001] The present invention relates to the field of kitchen appliances, and in particular to a stir-fry control method, a stir-fry control system and a cooker. Background Art

[0002] Stir-frying is an important cooking method in Chinese cuisine. Stir-frying requires the stove to provide instantaneous high heat to achieve the optimal cooking firepower state; while non-stir-frying does not require too much firepower, achieving the purpose of energy conservation and emission reduction and lowering the temperature rise of product use. Therefore, the stir-frying control method can be used to improve the cooking experience while saving gas consumption and playing the role of energy conservation and emission reduction.

[0003] The existing stir-fry control methods generally achieve the purpose of increasing the instantaneous heat load by instantaneously increasing the gas flow rate of the outer or inner gas circuit of the burner. However, when using this type of control method, the gas flow rate of the inner or outer gas circuit often produces a throttling effect, causing the gas supply pressure of the inner or outer gas circuit to drop, thereby causing the burner's entrainment capacity to inevitably decrease as the gas pressure drops, resulting in insufficient air entering the burner and insufficient gas mixing, which in turn produces yellow flames or excessively high smoke. At the same time, the national standard heat load test method requires that the deviation between the measured converted heat load value of the stove and the rated heat load value should be within ±10%. If the stir-fry time of the stove is not controlled, the safety and reliability of the stove may be damaged. Summary of the Invention

[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

[0032] like Figures 1 to 4 As shown, Figure 1 The flowchart of a stir-fry control method provided by the present invention is shown. Figure 2 A three-dimensional schematic diagram of a stove provided by the present invention is shown. Figure 3 A partial top view of a cooker provided by the present invention is shown. Figure 4 The figure shows a logic diagram of a stove provided by the present invention in a national standard heat load test.

[0033] The stir-fry control method of the embodiment of the present invention is applied to a stove. The stove includes a main gas circuit 1, a controller 2, and a flow detector. The flow detector is communicatively connected to the controller 2. The flow detector is arranged on the main gas circuit 1 to detect a first actual flow value Q1 of the main gas circuit. The stir-fry control method includes: setting a rated heat load K in the controller 2; the controller 2 starts the stove to enter a stir-fry mode according to a received stir-fry signal; the controller 2 calculates a first actual heat load value K1 according to the obtained first actual flow value Q1, and compares K1 with K; when K1 ≥ 1.1K, the controller 2 calculates a stir-fry time T 爆 And time T1; and when T1 = T 爆 When , the controller 2 controls the cooker to turn off the stir-fry mode.

[0034] like Figure 1 、 Figure 2 and Figure 4 As shown, after the cooker is ignited and started, the gas required for combustion enters the burner 3 completely through the main gas path 1. A flow detector is set on the main gas path 1 to detect the first actual flow value Q1 of the gas passing through the main gas path 1. Then, the first actual heat load value K1 is calculated by the controller 2. During stir-frying, the heat load of the cooker often exceeds 10% of the national standard limit of 5.23KW. Therefore, the rated heat load K of the cooker is set in the controller 2, and K is preferably the national standard value of 5.23kW. When the stir-frying mode is started, the first actual heat load value K1 ≥ 1.1K, and the controller 2 calculates the stir-frying time T according to the first actual heat load value K1. 爆 , start the timer T1 after stir-frying, when T1=T 爆 When the first actual heat load value K1 is larger, the stir-frying time is reduced accordingly, thereby increasing the instantaneous heat load during cooking and controlling the measured converted heat load value of the cooker to meet the national standard test standard.

[0035] In a preferred embodiment of the present invention, the stir-frying time T 爆 Calculate according to the following formula:

[0036] Among them, the rated heat load value K is set to 5.23kW. When the calculated first actual heat load value K1 during stir-frying is exactly 1.1 times the rated heat load value K, that is, K1 = 5.753kW, substitute it into the formula The stir-frying time T can be calculated 爆 =1min, when the calculated first actual heat load value K1 during stir-frying is 1.5 times the rated heat load value K, that is, K1=5.753kW, substitute into the formula The stir-frying time T can be calculated 爆 =0.2min, thereby preventing the measured converted heat load of the stove from exceeding the required value of the national standard test within three minutes in the national standard heat load test method. A simple calculation formula for the maximum stir-fry heat load and stir-fry duration is provided, which can be used to save a lot of repeated verification of the correlation between the maximum stir-fry heat load and stir-fry duration, thereby improving product research and development efficiency.

[0037] In a preferred embodiment of the present invention, the first actual heat load value K1 is calculated according to the following formula: K1 = Q1 × q × α, where q is the lower calorific value of the gas at 15°C and 101.3 kPa, in units of MJ / m, and α is the environmental correction factor.

[0038] The lower calorific value of gas is the heat released when the unit volume of gas is completely burned and the combustion products are cooled to the temperature before combustion (usually the ambient temperature). Cookers usually use natural gas or liquefied gas as fuel. The lower calorific value of natural gas is 35MJ / m 3 Since liquefied petroleum gas is in liquid state, its lower calorific value is 42MJ / Kg, and α is the environmental correction factor, which can be calculated by the formula Calculate, where t g is the gas temperature in the flow detector, in °C; p amb is the atmospheric pressure during testing, in kPa; p m is the relative static pressure of the gas in the measured flow detector, in kPa; s is the temperature t g The saturated water vapor pressure at the time of saturation is in kPa. In this way, the first actual heat load value K1 of the cooker can be calculated by simply detecting the first actual flow value Q1 of the gas flowing through the main gas path 4.

[0039] In a preferred embodiment of the present invention, before the stove starts the stir-fry mode, the process further includes: determining whether the stove is in a high-fire mode; when the stove is in the high-fire mode, the controller 2 activates the stir-fry mode.

[0040] like Figure 1 As shown, after the stove is started, the controller 2 first determines whether the stove is in high-fire mode. When the stove is in high-fire mode, the controller 2 activates the stir-fry mode. Otherwise, the controller 2 controls the stove to enter the stir-fry standby mode, which can prevent the stir-fry mode from being mistakenly started in the low-fire mode of the stove, thereby avoiding danger caused by mistakes.

[0041] In a preferred embodiment of the present invention, the stove includes a burner 3, a main gas line 4, and a control switch 5, which are connected in sequence. The main gas line 4 is connected to the main gas line 1 via the control switch 5. Determining whether the stove is in high-fire mode includes: a flow detector detecting a second actual flow value Q2 of the main gas line 4 and calculating a second actual heat load value K2; when 0.7K≤K2≤K, the controller 2 determines that the stove is in high-fire mode.

[0042] like Figure 1 and Figure 2 As shown, the gas enters the burner 3 from the main gas path 1 through the control switch 5 and the main gas path 4 in sequence. The flow detector arranged on the main gas path 1 is used to measure the gas flow value entering the burner 3 through the main gas path 1 in real time, and the controller 2 can calculate the second real-time thermal load value Q2 of the gas in real time. When it is necessary to determine whether it is a high-fire mode or a low-fire mode, the flow detector measures the second actual flow value Q2 of the main gas path 4 and feeds it back to the controller 2. The controller 2 calculates the second actual thermal load value K2. The above-mentioned actual thermal load value calculation formula can be used. When 0.7K≤K2≤K, the controller 2 determines that the stove is in the high-fire mode and controls the stir-fry mode to enter the active state. When 0≤K2<0.7K, the controller 2 determines that the stove is in the low-fire mode and controls the stir-fry mode to enter the standby state.

[0043] In a preferred embodiment of the present invention, the control switch 5 is a plug valve, and the stove further includes an angle sensor for detecting a rotation angle θ of the plug valve. The angle sensor is connected to the plug valve and is in communication with the controller 2. Determining whether the stove is in high-fire mode includes: adjusting the angle of the plug valve to adjust the stove's firepower, the angle sensor detecting the rotation angle θ of the plug valve; and when 75°≤θ≤105°, the controller 2 determines that the stove is in high-fire mode.

[0044] like Figure 1 and Figure 2As shown, the angle sensor is provided at the corresponding position of the plug valve. When the plug valve is rotated, the rotation angle of the plug valve can be measured. The plug valve acts as a control switch 5 to control the fire power of the stove. The knob provided on the plug valve drives the valve stem of the plug valve to be pressed down and rotated 90° counterclockwise to ignite and start the stove. After being released, due to the error that may be caused by manual operation, when the actual rotation angle θ of the valve stem of the plug valve is between 75° and 105°, the angle sensor transmits a signal to the controller 2, and the controller 2 controls the stir-fry mode to enter the activation state. When the knob is released and the plug valve is adjusted to rotate clockwise so that its actual rotation angle θ is less than 75°, or rotated counterclockwise so that its actual rotation angle θ is greater than 105°, the controller 2 controls the stir-fry mode to enter the standby state after receiving the signal from the angle sensor.

[0045] In a preferred embodiment of the present invention, when K1≥1.1K, the controller 2 calculates the stir-frying time T 爆 And start timing T1, also include: when T1<T 爆 When 0°≤θ<75° or 105°<θ≤180°, the controller 2 turns off the stir-fry mode.

[0046] like Figure 1 and Figure 2 As shown, after entering the stir-fry mode, the controller 2 calculates the stir-fry time T 爆 And start timing T1, when T1<T 爆 When the angle between the position of the valve stem and the initial state is between 105° and 180°, or between 0° and 75°, the controller 2 determines that the stove enters the low fire mode and turns off the stir-fry mode.

[0047] In a preferred embodiment of the present invention, the cooker includes a stir-fry button electrically connected to the controller 2 , and the controller 2 activates the cooker to enter a stir-fry mode according to a received stir-fry signal.

[0048] like Figure 1 As shown, the stir-fry button is electrically connected to the controller 2, and the stir-fry button is provided with an indicator light, and preferably a sound prompt is added. When the controller 2 determines that the stove is in the high-fire mode, it sends a signal to the stir-fry button, so that the stir-fry button lights up and emits a sound prompt. When stir-frying is needed, press the stir-fry button to send the stir-fry signal to the controller 2. If the controller 2 determines that the stove is in the low-fire mode, the stir-fry button is not activated, so that the stir-fry button is in an invalid state, and no light is turned on or sound is emitted, thereby preventing the user from accidentally touching the stir-fry button and mistakenly entering the stir-fry mode.

[0049] In a preferred embodiment of the present invention, when K1≥1.1K, the controller 2 calculates the stir-frying time T 爆And start timing T1, also include: when T1<T 爆 When the stir-fry button is pressed, controller 2 turns off the stir-fry mode.

[0050] like Figure 1 As shown, when T1<T 爆 In addition to adjusting the stopcock to put the stove into low fire mode to exit the stir-fry mode, you can also exit the stir-fry mode by pressing the stir-fry key. The specific steps are: pressing the stir-fry key, the stir-fry key transmits the signal to the controller 2, and the controller 2 turns off the stir-fry mode.

[0051] In a preferred embodiment of the present invention, after the controller 2 turns off the stir-fry mode, the controller 2 further includes: setting the standby time T 待 ; Controller 2 times T2 and compares T2 with T 待 ; When T2 = T 待 When the stove is in high fire mode, the controller 2 reactivates the stir-fry mode.

[0052] like Figure 1 As shown, the standby time T is set in the controller 2. 待 , controller 2 turns off the stir-fry mode and starts timing T2, so that the cooker exits the stir-fry mode and the time is T 待 The stir-fry mode cannot be activated again within this time, thereby avoiding repeated activation of the stir-fry function that causes the measured converted heat load value of the stove to exceed 1.1 times the rated heat load value, thereby improving the safety and reliability of the stove.

[0053] The stir-fry control system of the embodiment of the present invention is controlled by the aforementioned stir-fry control method. The stir-fry control system includes a burner 3, a main gas circuit 4, and a control switch 5. The burner 3 includes an outer ring burner 31 and an inner ring burner 32. The main gas circuit 4 includes an outer ring gas circuit 41 and an inner ring gas circuit 42. The outer ring burner 31 is connected to the control switch 5 via the outer ring gas circuit 41, and the inner ring burner 32 is connected to the control switch 5 via the inner ring gas circuit 42. The stir-fry gas circuit 6 is connected to the outer ring burner 31. The cooker also includes a stir-fry gas circuit 6 and a throttle valve 7, which are connected in sequence. The stir-fry gas circuit 6 is connected to the outer ring burner 31, and the throttle valve 7 is connected to the main gas circuit 1. The throttle valve 7 is in communication with the controller 2.

[0054] like Figure 2 and Figure 3As shown, in the high-fire mode, the gas enters the outer-ring burner 31 through the outer-ring gas path 41 and enters the inner-ring burner 32 through the inner-ring gas path 42. When the firepower of the stove changes from the high-fire mode to the low-fire mode, it can be adjusted by the knob set on the plug valve. When the rotation angle of the plug valve is rotated counterclockwise from 90° to 180°, the gas flow on the outer-ring gas path 41 decreases until it reaches zero, thereby adjusting the firepower of the stove. When the stir-fry mode is started, the controller 2 opens the throttle valve 7. The gas enters the main gas path 4 and enters the outer-ring burner 31 through the stir-fry gas path 6 at the same time. The stir-fry gas path 6 does not pass through the plug valve. Therefore, without affecting the outer-ring gas path and the inner-ring gas path, the stove has the function of instantaneous heat load increase, and the instantaneous heat load increase is large and is not limited by the rated heat load.

[0055] Preferably, the throttle valve 7 can be a common solenoid valve or a motor valve with gear adjustment, so that the amount of additional gas passing through the stir-frying gas path 6 can be adjusted at will according to the heat load value required for stir-frying.

[0056] In a preferred embodiment of the present invention, the stir-frying control system also includes a nozzle 8 arranged on the side of the stir-frying gas circuit 6 close to the outer ring burner 31, and a side hole 81 is opened on the side wall of the nozzle 8 to supply more air to the outer ring burner 31 in the stir-frying mode.

[0057] like Figure 2 and Figure 3 As shown, the supply of gas by the stir-frying gas circuit 6 causes the proportion of gas in the outer ring burner 31 to increase, which may cause abnormal combustion of the outer ring burner 31, resulting in yellow flames or a significant increase in the CO content in the flue gas. A nozzle 8 is provided at the end of the stir-frying gas circuit 6 near the outer ring burner 31. The side wall of the nozzle 8 is provided with a side hole 81. When the gas passes through the stir-frying gas circuit 6 and flows through the side hole 81, the negative pressure brings air outside the side hole 81 into the outer ring burner 31 for mixing, thereby resolving the problem of yellow flames or a significant increase in the CO content in the flue gas. Of course, if the stir-frying gas circuit 6 is connected to the inner ring burner 32, the yellow flame or incomplete combustion produced by the inner ring burner 32 can be reduced.

[0058] The cooker in the embodiment of the present invention is controlled by the aforementioned stir-fry control method.

[0059] The cooker according to the embodiment of the present invention includes the aforementioned stir-fry control system.

[0060] The stir-fry control method of the present invention controls the duration of stir-frying according to the rated heat load value set in the controller 2 and the actual heat load value obtained by the flow detector without affecting the normal gas channel and the rated heat load, so that the greater the actual heat load value, the shorter the stir-frying duration, thereby avoiding the heat load of the stove exceeding 10% of the rated heat load in the national standard heat load test method; by adding an additional stir-fry gas path 6 connected between the outer ring burner 31 and the main gas path 1, and controlling the on and off of the stir-fry gas path 6 with a throttle valve 7, the stove can increase the instantaneous heat load by a large margin without affecting the normal gas channel and the rated heat load; by arranging a nozzle 8 with a side hole 81 on the side of the stir-fry gas path 6 close to the outer ring burner 31, more air is added during the stir-frying process, avoiding the generation of yellow flames or excessive smoke during the stir-frying process.
