Description

Technical Field

[0001] The invention relates to the technical field of gas cooker manufacturing, in particular to a cooker with a fire power adjustment indicator light and a fire power display method. Background Art

[0002] In existing gas cookers, it is difficult for users to observe the flame due to the use of an energy-gathering pan stand.

[0003] In order to enable users to better observe the state of the flame, an indicator light is usually added to the panel at the knob for adjusting the fire power, and the fire power of the gas stove is displayed by the indicator light.

[0004] When the combustion is normal or when the flame is accidentally extinguished, the indicator light will display different colors of light to remind the user of the combustion status of the stove.

[0005] However, the indicator lights in existing solutions are all in the shape of a lamp ring and cannot clearly indicate the size of the flame.

[0006] Therefore, how to accurately display the fire power of the gas stove has become a technical problem that those skilled in the art need to solve urgently. Summary of the Invention

[0007] In view of the above-mentioned defects of the prior art, the present invention provides a stove with a firepower adjustment indicator light and a firepower display method, the purpose of which is to accurately display the firepower of the gas stove.

[0008] To achieve the above objectives, the present invention discloses a stove with a fire power adjustment indicator light, which includes a solenoid valve for controlling the opening and closing of a gas pipeline, a gas flow control valve for adjusting the gas intake amount, and a rotary handle for adjusting the opening of the gas flow control valve.

[0009] Wherein, the valve core of the gas flow control valve is provided with a deflection angle sensor;

[0010] The deflection angle sensor is used to collect the deflection angle of the valve core and convert the deflection angle into an electrical signal;

[0011] The gas cooker panel located outside the rotating handle is provided with a plurality of LED display lights;

[0012] A plurality of said LED display lights are arranged around the rotation axis of said rotary handle, i.e. said valve core;

[0013] The deflection angle sensor, the solenoid valve, the flame detector for detecting whether the stove burner is ignited, and all the LED display lights are connected to the control board;

[0015] Preferably, the deflection angle sensor is a Hall sensor, a resistive sensor or a position encoder.

[0016] The present invention also provides a fire power display method for controlling all LED display lights of the cooker with a fire power adjustment indicator light, comprising the following steps:

[0017] Step 1: When the deflection angle sensor detects that the valve core deflection angle of the gas flow control valve has reached the ignition point, the control panel instructs the ignition device to ignite and controls the solenoid valve to open, inputting gas to the stove burner. At the same time, the LED indicator light at the ignition position on the gas stove panel lights up;

[0023] If the control board receives an electrical signal indicating that there is no flame from the flame detector, step 6 is executed;

[0024] Step 4: After the deflection angle of the valve core detected by the deflection angle sensor remains unchanged for a period exceeding a preset time, the control board finds a corresponding LED light lighting scheme from a deflection angle database according to the deflection angle of the valve core, and controls the corresponding LED display light to light up;

[0025] Step 5, after each deflection of the valve core, the deflection angle of the deflection angle sensor is measured and steps 2 and 4 are repeated;

[0026] Step 6: When an electrical signal indicating that no flame exists is obtained from the flame detector, the solenoid valve is closed and all the LED display lights are controlled to flash;

[0027] Step 7: When the deflection angle of the valve core collected by the deflection angle sensor reaches a closed state, close the solenoid valve and all the LED display lights.

[0028] Preferably, the adjustment range of the valve core is 0 degrees to 165 degrees; when the valve core is rotated to 30 degrees, 60 degrees, 90 degrees, 120 degrees and 150 degrees, the LED display lights are provided at the positions indicated by the corresponding indicator marks on the rotating hand.

[0053] Example

[0054] like Figure 1 As shown, the stove with a fire power adjustment indicator light includes a solenoid valve 2 for controlling the opening and closing of the gas pipeline, a gas flow control valve 1 for adjusting the gas intake amount, and a rotary handle for adjusting the opening of the gas flow control valve 1.

[0055] The valve core 11 of the gas flow control valve 1 is provided with a deflection angle sensor 3;

[0056] The deflection angle sensor 3 is used to collect the deflection angle of the valve core 11 and convert the deflection angle into an electrical signal;

[0057] The gas cooker panel located outside the rotary handle is provided with a number of LED display lights 4;

[0058] Several LED display lights 4 are arranged around the rotation axis of the rotary handle, i.e. the valve core 11;

[0059] The deflection angle sensor 3, the solenoid valve 2, the ignition device 8 for ignition, the flame detector 6 for detecting whether the stove burner 5 is ignited, and all the LED display lights 4 are connected to the control board 7;

[0060] The control panel 7 controls the operation of all LED display lights 4 and the solenoid valve 2 according to the electrical signals sent by the flame detector 6 and the deflection angle sensor 3 .

[0061] The present invention installs a deflection angle sensor 3 on the valve core 11 of the gas flow control valve 1 to detect the rotation angle of the valve core 11 in real time, and transmits the rotation angle signal to the control board 7 in the form of an electrical signal.

[0062] The control board 7 lights up the corresponding LED display light 4 based on the rotation angle of the valve core 11 detected by the deflection angle sensor 3 .

[0063] The present invention can light up the LED display light 4 according to the real-time firepower change of the user, so that the user can conveniently know the flame burning status at the burner without bending over to observe the flame.

[0064] In some embodiments, the deflection angle sensor 3 is a Hall sensor, a resistive sensor, or a position encoder.

[0065] like Figure 2 and Figure 3 As shown, the present invention also provides a fire power display method for controlling all LED display lights 4 of the stove with fire power adjustment indicator light, comprising the following steps:

[0066] Step 1: When the deflection angle sensor 3 detects that the deflection angle of the valve core 11 of the gas flow control valve 1 reaches the ignition point, the control panel 4 instructs the ignition device 8 to ignite, and controls the solenoid valve 2 to open, inputting gas to the stove burner 5. At the same time, the LED indicator light 4 at the ignition position on the gas stove panel lights up; all LED indicator lights flash.

[0067] Step 2: Detect whether the deflection angle of the valve core 11 collected by the deflection angle sensor 3 reaches the closed state;

[0068] If the deflection angle of the valve core 11 detected by the deflection angle sensor 3 reaches the closed state, step 7 is executed;

[0069] If the deflection angle of the valve core 11 detected by the deflection angle sensor 3 does not reach the closed state, step 3 is executed;

[0070] Step 3: The control board 4 performs the following steps according to the electrical signal of the flame detected by the flame detector 6 located on one side of the stove burner 5;

[0071] If the control board 4 receives an electrical signal indicating the presence of flame from the flame detector 6, step 4 is executed;

[0072] If the control board 4 receives an electrical signal indicating the absence of flame from the flame detector 6, step 6 is executed;

[0073] Step 4: After the deflection angle of the valve core 11 detected by the deflection angle sensor 3 remains unchanged for a period exceeding a preset time, the control board 4 finds a corresponding LED light lighting scheme from the deflection angle database according to the deflection angle of the valve core 11 and controls the corresponding LED display light 4 to light up;

[0074] Step 5: Repeat steps 2 and 4 for each deflection of the valve core 11 and the deflection angle of the deflection angle sensor 3;

[0075] Step 6: When an electrical signal indicating that no flame exists is obtained from the flame detector 6, the solenoid valve 2 is closed and all LED display lights 4 are controlled to flash;

[0076] Step 7: When the deflection angle of the valve core 11 detected by the deflection angle sensor 3 reaches the closed state, the solenoid valve 2 and all the LED display lights 4 are closed.

[0077] In actual application, during the ignition stage of the stove, when the gas flow control valve 1 is rotated to the ignition position, the control board 7 instructs the ignition device 8 to ignite and opens the solenoid valve 2. At this time, the gas path is connected and ignition begins.

[0078] And the LED display light 4 corresponding to the ignition state lights up.

[0079] After the ignition is successful, the flame detector 6 transmits the electrical signal of the presence of flame to the control panel 7;

[0080] The control board 7 instructs the LED display lamp 4 corresponding to the ignition state to remain lit.

[0081] During use, when the fire power is adjusted through the gas flow control valve 1 , the deflection angle sensor 3 transmits the deflection angle of the valve core 11 to the control board 7 .

[0082] The control board 7 calculates the corresponding LED lights that need to be lit through the built-in algorithm according to the current deflection angle of the valve core 11, obtains the lighting plan of the LED display lights 4 from the database, and then lights up the corresponding LED display lights 4.

[0083] When turning off the fire, rotate the gas flow control valve 1 to the closed position, the solenoid valve 2 closes the gas passage, the flame goes out, and all LED display lights 4 are turned off.

[0084] When an unexpected flameout occurs during use, the flame detector 6 receives an electrical signal indicating the absence of flame and feeds it back to the control board 7;

[0085] The control board 7 closes the solenoid valve 2 and cuts off the gas passage. At this time, the valve core 11 of the gas flow control valve 1 is still at the deflection angle of opening the gas passage. The control board 7 instructs all LED display lights 4 to flash red to remind the user to close the gas flow control valve 1 in time.

[0086] In some embodiments, the adjustment range of the valve core 11 is 0 degrees to 165 degrees; when the valve core 11 rotates to 30 degrees, 60 degrees, 90 degrees, 120 degrees and 150 degrees, the positions indicated by the corresponding rotating hand indicator marks are provided with LED display lights 4.

[0087] In some embodiments, each LED display light 4 includes two colors and can light up at three brightness levels: high brightness, medium brightness, and dim brightness; one color is red, and the other color is blue or white.

[0088] In some embodiments, in step 7, all LED display lights 4 flash in red and high brightness.
