Description

Gas stove control method based on pressing type knob

Technical Field

The invention relates to the technical field of gas cookers, in particular to a gas cooker control method based on a push type knob.

Background

Gas stoves sold in the market at present are divided into single-hole stoves, double-hole stoves and multi-hole stoves with more than three holes according to the number of stove holes, each stove hole is provided with a corresponding plug valve, a knob is installed on a valve rod of each plug valve, and a consumer operates the knob to realize ignition, fire shutoff and firepower adjustment.

Specifically, the operation process of the gas stove is as follows: the knob is pressed down firstly, then the knob can be rotated anticlockwise to cross the self-locking limiting device in the plug valve, the knob can not be rotated when the knob is rotated to the maximum firepower device in the plug valve, and at the moment, firepower size adjustment can be realized only after the knob is loosened. Therefore, if it is desired to ignite, then fire and finally shut down the fire during cooking, the above-described operation of the knob must be repeated. The knob is pressed and rotated in the frequently-operated process in the cooking process, the plug valve can cause poor tightness due to mechanical abrasion, even if the plug valve is closed after the cooking is finished, the leakage amount is gradually increased along with the time lapse, and the cooking stove is not safe and wastes gas. In addition, in the cooking process, people often encounter the problem that pans and the like need to be washed in the intermittent process, at the moment, consumers often rotate a knob to adjust firepower to the minimum firepower position of a plug valve in order to save fuel gas, and after washing is finished, the firepower is adjusted to the position of the previous plug valve again, so that mechanical abrasion air leakage of the plug valve is increased, the service life of a gas stove is shortened, inconvenience is caused, and potential safety hazards exist.

Currently, some techniques (e.g., patent No. 201310678485.5) have solved the safety problem and the operation convenience problem. In actual use, however, cooking recipes are different, and safety is also reduced, for example, for a part of recipes, the "10-minute automatic fire-off time" is easy to cause carbonization and combustion of food materials and fire, and the "10-minute automatic fire-off time requires to close the knob to rotate the knob again to ignite" increases the number of times of rotation of the knob to cause abrasion of the plug valve, thereby causing increase of air leakage; in addition, the convenience experience is correspondingly reduced due to different used crowds, for example, the operation of the 'three-step timing setting method' is complex, so that the old people are difficult to learn or even unwilling to learn, meanwhile, the old people are easy to lock in the slow ignition operation, so that the ignition is not performed, and the young people turn off the fire automatically and interrupt the cooking in the cooking process, so that the experience is poor.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

The push type knob comprises a plug valve, and a microswitch, a point contact switch and a knob which are arranged on the plug valve. Therefore, the user can operate the point contact switch or the micro switch by pressing down/loosening the knob to realize the start/stop of the ignition of the gas stove, and can also operate the micro switch by rotating the knob counterclockwise/clockwise to realize the start/stop of the ignition of the gas stove.

The invention is a gas stove control method developed based on the pressing knob, and specifically, a user can operate a gas stove by spinning (rotating and pressing), pressing (pressing, and rotating (clockwise or counterclockwise). Accordingly, the spinning (rotating and pressing), pressing (point pressing, short pressing, long pressing), and rotating operations may be expressed as spinning signals, pressing signals (point pressing signals, short pressing signals, long pressing signals), and rotating signals, i.e., spinning signals, pressing signals (point pressing signals, short pressing signals, long pressing signals), and rotating signals are not electric signals but an operation manner in the present invention.

In the working process, the controller can drive the gas stove to be started according to the spinning signal acquired in real time and enter a timing mode. When the gas stove has the electronic child lock function, in the state of releasing the electronic child lock, a user presses down the knob to rotate anticlockwise to cross the self-locking limiting position of the plug valve, the gas stove is immediately ignited and starts to burn, and in the burning state, the gas stove works in a preset timing mode; in addition, when the gas stove does not have the electronic child lock function, as long as a user presses down the knob and rotates anticlockwise to pass through the self-locking limiting position of the plug valve, the gas stove is immediately ignited and starts to burn, and in the burning state, the gas stove works in a preset timing mode. Specifically, the timing mode comprises an ignition pressure time-duration mode, an ignition pressure fire-off mode, a time-fire-off mode, a fire-duration mode or a constant time mode, so that a user can select any required mode in advance before work begins, and the flexibility is strong. Specifically, the method comprises the following steps:

and under the pressure ignition continuous time mode, updating the automatic fire-off time according to the pressure ignition signal.

And under the point-pressure fire-off mode, the gas stove is driven to be closed or opened according to the pressing signal.

And under the continuous time-fire-off mode, the gas stove sequentially enters the point pressure continuous time mode and the point pressure fire-off mode.

Under the fire-off continuous mode, the gas stove sequentially enters the point pressure fire-off mode and the point pressure continuous mode;

in the constant time mode, the gas range does not respond to the point pressure signal.

The point pressing signal can be a signal with the time for pressing the knob to be less than 3 seconds, the short pressing signal can be a signal with the time for pressing the knob to be not less than 3 seconds, the long pressing signal can be a signal with the time for pressing the knob to be more than 10 seconds, the limitation is not taken, a manufacturer can set the signal according to actual conditions, and the flexibility is high.

Accordingly, in the ignition pressure continuous mode, the ignition pressure fire-off mode, the continuous time fire-off mode, the fire-off continuous mode or the constant time mode, when the gas stove is in a combustion state, the fire power of the gas stove can be adjusted according to the rotation signal. That is, between the minimum fire position and the maximum fire position of the plug valve, the fire size can be adjusted by rotating the knob clockwise or counterclockwise. Wherein, when the user rotates the knob clockwise until the stop gas position of plug valve, the gas-cooker finishes working.

Further, under an ignition pressure continuous mode, an ignition pressure fire-off mode, a continuous time fire-off mode, a fire-off continuous mode or a constant time mode, when the gas stove is in a combustion state, if a short pressure signal is acquired, a real-time timing mode is entered; meanwhile, in the real-time timing mode, if the point pressure signal is acquired within the preset time, the timing setting mode is entered to update the automatic fire-off time, and if the point pressure signal is not acquired within the preset time, the real-time timing mode is automatically exited.

It should be noted that no matter the gas stove is in the pressure on-off mode, the time-off mode, the off-on-time mode or the constant-time mode, the gas stove can enter the real-time timing mode as long as the gas stove is in the combustion state and the short-pressure signal is obtained. The point pressing signal can be a signal with the time for pressing the knob to be less than 3 seconds, the short pressing signal can be a signal with the time for pressing the knob to be not less than 3 seconds, the limitation is not taken, a manufacturer can set the point pressing signal according to actual conditions, and the flexibility is high.

Specifically, the specific method for updating the automatic fire-off time by the button in the real-time timing mode can be referred to as "a method for operating a gas stove knob" (patent No. 201310678485.5), and will not be described in detail herein.

Referring to fig. 1, fig. 1 shows a flowchart of a gas stove control method based on a push knob according to a first embodiment of the present invention, which includes:

s101, a spinning signal is obtained, and the gas stove is driven to be started and enters a timing mode according to the spinning signal.

In this embodiment, the timing mode is a dot-and-dash timing mode.

And S102, in the point pressure continuous time mode, if the controller acquires a point pressure signal, entering a continuous time mode to update the automatic fire-off time.

For example, if the preset time of the dot press continuous time mode is 6 minutes, the automatic fire off time needs to be updated to 10 minutes. When the electronic child lock is released, the knob is pressed down to rotate anticlockwise to pass through the self-locking limiting position of the plug valve, the gas stove is immediately ignited and starts to burn, and at the moment, the gas stove enters a point pressing continuous mode; then, in the next 6 minutes, as long as the user presses the button, the gas stove immediately enters a time-continuous timing mode, and the user can update the automatic fire-off time to be 10 minutes through the button; after the updating is finished, the gas stove exits the timing mode and enters the point pressure timing mode again; subsequently, if the ignition pressure signal is not received in the next 10 minutes, the gas stove is automatically turned off.

For example, the method of setting the auto-off time by the button is as follows: the user clicks the button, the gas-cooker immediately enters the continuous timing mode, the gas-cooker sends out a prompt tone "beep" at the moment, the knob is clicked for 1 time, if the continuous timing step is 5 minutes, the continuous timing is 5 minutes, the knob is clicked again, the gas-cooker sends out a prompt tone "beep" to indicate that the knob is clicked for 2 times, the continuous timing is 10 minutes, the rest is done by analogy, the knob is clicked for 5 times, the continuous timing is 25 minutes, then, if the knob is not clicked within 5 seconds, the gas-cooker sends out a prompt tone "beep", the continuous timing time is automatically confirmed, the new continuous timing time 25 minutes replaces the preset automatic fire-off time to start countdown work.

For another example, the method for setting the automatic fire-off time by the button is as follows: the user clicks the button, the gas stove immediately enters the timing mode, then the knob is clicked, the gas stove sends out a prompt tone 'beep', the knob is clicked for 1 time, if the timing step is 5 minutes, the timing is 5 minutes, the knob is clicked again, the gas stove sends out a prompt tone 'beep', the knob is clicked for 2 times, the timing is 10 minutes, and so on, the knob is clicked for 5 times, the timing is 25 minutes, then, if the knob is not clicked within 5 seconds, the gas stove sends out a prompt tone 'beep', the timing time is automatically confirmed, the new timing time 25 minutes replaces the preset automatic fire-off time to start countdown work.

Referring to fig. 2, fig. 2 shows a flowchart of a gas cooker control method based on a push knob according to a second embodiment of the present invention, which includes:

s201, a spinning signal is obtained, and the gas stove is driven to be started and enters a timing mode according to the spinning signal.

In this embodiment, the timing mode is an ignition and pressing fire-off mode.

And S202, under the point pressure fire shutting mode, if a point pressure signal is acquired, closing the gas stove and entering a temporary fire shutting mode.

S203, in the temporary fire-off mode, if a pressing signal is acquired, the gas stove is started and enters the spot-pressing fire-off mode, and otherwise, the gas stove enters the alarm mode.

For example, if the preset time of the spot-pressure fire-off mode is 6 minutes and the preset time of the temporary fire-off mode is 10 minutes. When the electronic child lock is released, the knob is pressed down to rotate anticlockwise to pass through the self-locking limiting position of the plug valve, the gas stove is immediately ignited and starts to burn, and at the moment, the gas stove enters a point-pressure fire-stopping mode; then, in the next 6 minutes, as long as the user presses the button, the gas stove is immediately turned off and enters a temporary fire-off mode; then, if a pressing signal (such as voltage, short voltage and long voltage) is received in the next 10 minutes, the gas stove is immediately ignited and enters an ignition and pressure shut-off mode again; then, if the user's ignition signal is not received in the next 6 minutes, the gas stove is automatically turned off.

It should be noted that, in the alarm mode, the gas stove continuously sends out the alarm prompt, and at this time, the alarm prompt can be released only by rotating the knob clockwise until the gas closing position of the plug valve.

For example, if the preset time of the ignition-off mode is 6 minutes, and the preset time of the temporary ignition-off mode is 10 minutes. When the electronic child lock is released, the knob is pressed down to rotate anticlockwise to pass through the self-locking limiting position of the plug valve, the gas stove is immediately ignited and starts to burn, and at the moment, the gas stove enters a point-pressure fire-stopping mode; then, in the next 6 minutes, as long as the user presses the button, the gas stove is immediately turned off and enters a temporary fire-off mode; then, if the spot pressure signal is not received in the next 10 minutes, the gas stove enters an alarm mode; and finally, continuously giving an alarm prompt to the gas stove in the next time, pressing down the knob at the moment, not igniting the gas stove, rotating the knob clockwise until the gas stop position of the plug valve is reached, and removing the alarm prompt.

In this embodiment, the timing mode is a time-fire off mode;

s302, under the time-delay and fire-off mode, the gas stove sequentially enters an ignition time-delay mode and an ignition and fire-off mode.

For example, if the preset time of the pressing and ignition continuation mode is 2 minutes, the preset time of the pressing and ignition off mode is 5 minutes. When the electronic child lock is released, the knob is pressed down to rotate anticlockwise to pass through the self-locking limiting position of the plug valve, the gas stove is immediately ignited and starts to burn, and at the moment, the gas stove enters a point pressing continuous mode; subsequently, within the next 2 minutes, if the ignition pressure signal is not received, the gas range enters the ignition pressure fire-off mode and prompts a "beep" sound. For the operation of the pressing-on-time mode and the pressing-on-fire mode, reference is made to the related descriptions of the first embodiment and the second embodiment.

Referring to fig. 4, fig. 4 shows a flow chart of a fourth embodiment of the gas stove control method based on the push type knob according to the present invention, which comprises:

In this embodiment, the timing mode is an off-on-time mode;

s402, under the fire-off and time-continuing mode, the gas stove sequentially enters an ignition and pressure fire-off mode and an ignition and pressure time-continuing mode.

For example, if the preset time of the pressing and extinguishing mode is 5 minutes, the preset time of the pressing and sustaining mode is 2 minutes. When the electronic child lock is released, the knob is pressed down to rotate anticlockwise to pass through the self-locking limiting position of the plug valve, the gas stove is immediately ignited and starts to burn, and at the moment, the gas stove enters a point-pressure fire-stopping mode; subsequently, within the next 5 minutes, if the spot pressure signal is not received, the gas range enters a spot pressure time continuous mode and prompts a "beep" sound. For the working process of the ignition and pressing extinguishing mode and the ignition and pressing continuous mode, reference is made to the related descriptions of the first embodiment and the second embodiment.

And S502, after the timing mode is finished, closing the gas stove and entering a warning mode.

S503, in the warning mode, if a pressing signal is acquired, the gas stove is started and enters the timing mode, and otherwise, the gas stove enters the alarm mode.

It should be noted that, in the warning mode, the gas stove continuously sends out the warning prompt, and at this time, the warning prompt can be released by pressing (pressing, short pressing, long pressing) the knob; under the alarm mode, the gas stove continuously sends out alarm prompts, and at the moment, the alarm prompts can be relieved only by rotating the knob clockwise until the gas closing position of the plug valve.

For example, if the timing mode is the pressing and extinguishing mode, the preset time of the pressing and extinguishing mode is 6 minutes, the preset time of the warning mode is 1 minute, and the preset time of the alarm mode is 2 minutes. When the electronic child lock is released, the knob is pressed down to rotate anticlockwise to pass through the self-locking limiting position of the plug valve, the gas stove is immediately ignited and starts to burn, and at the moment, the gas stove enters a point-pressure fire-stopping mode; then, in the next 6 minutes, if the spot pressure signal is not received, the gas stove is closed and enters an alarm mode; then, within the next 1 minute, the gas stove continuously sends out an alarm prompt, at the moment, the alarm prompt can be relieved in a knob pressing mode, the timing mode is started, and the timing is restarted for 6 minutes, but if a pressing signal is not received within 1 minute of the warning mode, the gas stove enters the alarm mode; and finally, continuously giving an alarm prompt by the gas stove in the next 2 minutes, pressing down the knob at the moment, not igniting the gas stove, rotating the knob clockwise until the gas stop position of the plug valve is reached, and removing the alarm prompt.

Referring to fig. 6, fig. 6 shows a flowchart of a sixth embodiment of a gas range control method based on a push type knob according to the present invention, which includes:

And pressing down the knob at the gas off position of the plug valve, pressing the knob until the prompt tone is heard to loosen the knob, and opening/releasing the electronic child lock. For example, when the knob is pressed down for not less than 10 seconds at the gas off position of the plug valve, a 'beep' is indicated, and the electronic child lock is opened; the prompt "beep" indicates the release of the electronic child lock.

and (1) in a non-ignition state, long-pressing the knob, and entering a parameter updating mode. If the working parameters are selected previously, prompting the current parameter position of the current working parameters (for example, the current position 1 circularly prompts 'beep', the current position 2 circularly prompts 'beep'), if the working parameters are not selected previously, the circular prompting is not performed, the gas stove works by adopting default working parameters, and the gas stove exits the parameter updating mode if no point pressing signal is obtained after the preset time;

and (2) in the parameter updating mode, pressing the knob, wherein the gas stove emits a prompt tone 'beep', indicating that the knob is pressed for 1 time, so that the corresponding position in the parameter list can be selected by pressing the knob, the knob is moved for 1 time, if the position is 1, the knob is pressed for 1 time, the knob is moved to the position for 2 seconds, the 'beep' is prompted in a circulating mode, the knob is pressed for 1 time, the knob is moved to the position for 3 times, the 'beep' is prompted in a circulating mode after 2 seconds, and the like, the gas stove returns to the position 1 after exceeding the highest position, and after the parameter selection is completed, the knob is pressed for a long time until the prompt tone is heard, the knob is loosened, and the working parameter state is confirmed.

And (3) taking the parameters at the corresponding positions in the parameter list as working parameters, simultaneously storing the working parameters into corresponding address storage units of a nonvolatile memory or volatile corresponding address storage units of the microprocessor, covering old working parameters or default working parameters in the corresponding address storage units, taking the working parameters as new working parameters to participate in the work of the gas stove, wherein the nonvolatile memory can be an on-chip memory of the microprocessor or an off-chip independent memory of the microprocessor.

Taking the initial position as a reference:
