Description

Technical Field

[0001] The present invention relates to the technical field of gas stove control, and in particular to a method for adjusting the initial firepower of a gas stove. Background Art

[0002] The heat load of gas stoves is increasing, gradually increasing from 3.8Kw, 4.0Kw, and 4.5Kw ten years ago to 5.0Kw and even 5.2Kw. However, household pots come in a variety of diameters, with the smallest diameter being 10cm, and commonly used pots ranging from 20cm to 40cm. Pots of different diameters hold different amounts of food and require different levels of heat. Generally, the larger the pot, the more food it can hold, and the higher the heat required. In actual cooking, using a small-diameter pot at the stove's maximum heat can lead to the following problems:

[0003] 1. Since small diameter pots can hold less food, the food is easily burnt when the fire is at maximum power.

[0004] 2. The diameter of the flame and high-temperature smoke generated by gas combustion is very large, often exceeding 32CM. When using pots with a diameter less than 32CM for cooking, a large part of the flame and high-temperature smoke cannot produce heat exchange with the bottom of the pot, causing a lot of heat to overflow outside the pot and cannot be used, thereby greatly reducing the actual thermal efficiency of the stove and wasting gas resources.

[0005] In this case, the heat is usually adjusted by adjusting the knob to match the heat to the pot. This requires a high level of attention to the heat, and often the food is burned due to failure to adjust the heat in time. Summary of the Invention

[0006] The object of the present invention is to provide a method for adjusting the initial firepower of a gas stove, which automatically adjusts the initial firepower to match the diameter of the pot, eliminates the need for manual adjustment of the initial firepower, and eliminates the need to constantly pay attention to the firepower situation, thereby reducing the requirement for the user to adjust the initial firepower, avoiding burning of food, and improving the user's cooking experience.

[0007] To achieve the objectives of the present invention, the present invention adopts the following technical solution: a method for adjusting the initial firepower of a gas stove, the gas stove comprising a pot support, a panel, and a stopcock, the panel being provided with a pot measurement activation button connected to a controller, the stopcock being connected to the controller and provided with a potential sensor, and further comprising an image sensor connected to the controller for measuring the pot diameter, the method comprising:

[0010] Calculate the pot diameter through the pot image and select the fire level that matches the pot diameter;

[0019] According to one embodiment of the present invention, the relationship between the pot diameter and the fire power level is:

[0020] The diameter range of less than 16cm corresponds to any gear from the first to the fourth gear.

[0021] The diameter range of 16-24cm corresponds to the fifth gear.

[0022] The diameter range of 24-30cm corresponds to the sixth gear.

[0023] The diameter range of 30-32cm corresponds to the seventh gear, and

[0041] like Figures 1 to 6 As shown in the relevant figures, a method for adjusting the initial firepower of a gas stove according to an embodiment of the present invention includes a pot support 1, a panel 2, and a plug valve 3 that can be driven both electrically and manually. The panel 2 is provided with a pot measurement activation button 4 connected to a controller. The plug valve 3 is connected to the controller and provided with a potential sensor. It also includes an image sensor 5 connected to the controller for measuring the diameter of the pot. The method for adjusting the initial firepower of the gas stove includes:

[0042] Place the pot 6 on the pot support 1 .

[0043] Activate the pan measurement mode and acquire an image of the pan 6.

[0044] The diameter of the pot 6 is calculated through the pot image and a fire level that matches the diameter of the pot 6 is selected.

[0045] Pressing the stopcock 3 starts ignition and automatically adjusts the initial firepower through the stopcock 3, thereby automatically adjusting the initial firepower to match the diameter of the cookware. There is no need to manually adjust the initial firepower, and there is no need to always pay attention to the firepower situation, which reduces the requirement for users to adjust the initial firepower, avoids burning food, and improves the user's cooking experience.

[0046] When the initial fire power adjustment is completed, the pot measurement mode is exited and the control program of the controller is switched to the normal control mode.

[0047] After switching to the normal control program mode, the user can adjust the opening of the plug valve 3 as needed.

[0048] like Figures 1 to 6 As shown in the relevant figures, in a preferred embodiment of the present invention, activating the cookware measurement mode includes manually activating a cookware measurement activation button 4 provided on the panel of the gas stove to activate the image sensor 5 .

[0049] After the image sensor 5 is activated, the circuit between the image sensor 5 and the controller is connected, and the controller obtains the image of the pot through the image sensor 5.

[0050] Before the image sensor 5 is activated, the circuit between the image sensor 5 and the controller is in an open state.

[0051] like Figures 1 to 6 As shown in the relevant figures, in a preferred embodiment of the present invention, collecting the image of the cookware includes: the controller obtains the image of the cookware 6 from any one of the perspectives of looking up, looking down, and looking from the side through the image sensor 5 .

[0052] like Figure 4 As shown, Figure 4 The method for obtaining a bottom-view image of the pot 6 is as follows: the image sensor 5 is positioned at the center of the burner 7 of the gas stove, so that the image sensor 5 faces upward to capture an image of the bottom of the pot 6 to measure the pot bottom diameter. In this embodiment, the distance between the image sensor 5 and the bottom of the pot 6 is 2-10 cm, so the image sensor 5 uses a wide-angle camera to capture an image of the entire pot bottom.

[0053] Among them, when the size of the bottom of the pot is equal to the size of the top of the pot, the outline size of the bottom of the pot shall prevail.

[0054] When the cookware is hemispherical, that is, the size of the bottom of the pot is smaller than the size of the top of the pot, the outline size of the top of the pot shall prevail.

[0055] like Figure 5As shown, the method for obtaining the overhead image of the pot 6 is: the image sensor 5 is set on the range hood 8 directly above the burner 7, so that the image sensor 5 takes the image of the pot 6 downward to measure the diameter of the pot 6.

[0056] like Figure 6 As shown, the method for obtaining the side view image of the pot 6 is: the image sensor 5 is set on the panel 2 of the gas stove and the camera probe is directed towards the pot 6 to obtain the side view image of the pot, thereby measuring the side diameter of the pot 6.

[0057] For example, the image sensor 5 is mounted on the panel 2 via a bracket.

[0058] In a preferred embodiment of the present invention, calculating the pot diameter from the pot image includes: a controller calculating the pot diameter from the pot image. A control program of the controller includes a program for measuring actual object size using image pixels, which is capable of calculating the actual diameter data of the pot 6 from the pot image.

[0069] When the heat load corresponding to the third gear is set to 2.0Kw, the initial cooking effect for pots with a diameter of less than 16cm is best.

[0070] When the controller measures that the diameter of the pot is less than 16 cm through the image sensor 5, the knob 31 of the stopcock 3 is pressed and rotated to ignite and then released. The controller controls the valve stem of the stopcock 3 to automatically adjust the firepower to the third gear, and the cooker works at the third and fifth gears.

[0071] When the heat load corresponding to the fourth gear is set to 3.0Kw, the initial cooking effect is better for pots with a diameter of less than 16cm.

[0072] When the heat load corresponding to the fifth gear is set to 3.5Kw, the initial cooking effect for pots with a diameter of 16-24cm is best.

The controller controls the valve stem of the electrically driven stopcock 3 to automatically adjust the firepower to the fifth gear, and the cooker works at the fifth gear.

[0074] When the heat load corresponding to the sixth gear is set to 4.0Kw, the initial cooking effect for pots with a diameter of 24-30cm is best.

[0078] When the heat load corresponding to the eighth gear is 5.2Kw, the initial cooking effect for pots with a diameter greater than 32cm is the best.

[0079] When the controller measures that the diameter of the pot is greater than 32 cm through the image sensor 5, the button 31 is pressed and rotated to ignite and then released. The controller controls the motor to drive the valve stem of the plug valve 3 to automatically adjust the firepower to the eighth gear, and the cooker works at the eighth gear.

[0080] In a preferred embodiment of the present invention, the stopcock automatically exiting the initial fire power adjustment mode includes: when the controller detects through the potential sensor that the stopcock is rotated into position, exiting the cookware measurement mode.

[0081] When the food is fried to a certain degree and needs to be adjusted to a lower heat or a higher heat, the knob 31 can be manually rotated to the desired gear and rotated into place, and then it can be automatically switched to the normal control program mode, thereby achieving a convenient switching effect.
