Description

Technical Field

[0001] This invention relates to the field of cooktops, and more specifically to a cooktop and a method for controlling the cooktop. Background Technology

[0002] In current cooktops, users adjust the heat by turning a rotary valve. Research on cooking methods has revealed that users exhibit different operating habits at different heat levels; for example, they don't cook continuously at high heat for extended periods. Cooking time and heat are generally controlled by the user, and external disturbances or leaving the house can easily lead to forgetting to turn off the stove, causing it to run for extended periods, resulting in burnt food and potentially even a fire. Furthermore, prolonged operation at high temperatures can cause the electrical components inside the cooktop to age prematurely, reducing its overall lifespan and potentially leading to short circuits and other hazards. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art where electrical components inside the stove are prone to aging when working at high temperatures for a long time, which reduces the overall service life of the stove and may also cause short circuits due to aging, thus creating a danger. The present invention provides a stove and a method for controlling the stove.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] The "first preset number of times," "second preset number of times," and "third preset number of times" referred to in this invention are all measured under the same standard. For example, the controller receives the rotation angle of the stopcock valve transmitted by the angle monitoring mechanism every 5 seconds, which corresponds to the real-time firepower of the stove. The counting module of the controller accumulates the specific number of times the corresponding firepower situation occurs and compares it with the preset conditions (preset number of times). The controller then decides whether to proceed to the next step.

[0006] This invention provides a cooktop, including a stopcock valve, and the cooktop further includes...

[0007] An angle monitoring mechanism is used to monitor the rotation angle of the plug valve;

[0008] A cooling mechanism, used to reduce the internal working temperature of the stove;

[0009] The controller is electrically connected to the angle monitoring mechanism and the cooling mechanism. The controller is configured to activate the timing module or the counting module when the rotation angle of the stopcock valve is within a preset angle range, and to issue a command to the cooling mechanism to control the cooling mechanism to start when the timing module or the counting module of the controller reaches a preset condition.

[0010] In this solution, the stove's heat level is determined by monitoring the rotation angle of the stopcock valve. The controller monitors the duration of the stove operating at the same heat level using its timing or counting module, and determines whether this duration exceeds a preset condition. If the duration exceeds the preset condition, the controller sends a command to the cooling mechanism to lower the stove's internal operating temperature. This invention prevents the stove from operating for extended periods due to the user forgetting to turn off the stove, thus avoiding prolonged high temperatures that could lead to aging of internal electrical components and improving the safety of stove use.

[0011] Preferably, the cooling mechanism includes a fan, the air inlet of the fan is connected to the outside of the stove, the inner cavity of the stove is provided with an air duct, one end of the air duct is set towards the electrical components inside the stove, and the air outlet of the fan is connected to the other end of the air duct.

[0012] In this solution, a fan is installed inside the stove to cool the electrical components. When the fan is turned on, cool air from outside the stove flows from one end of the air duct to the other and then to the surface of the electrical components, thereby carrying away the heat from the surface of the electrical components and cooling them down.

[0013] Preferably, the stove further includes a burner, and the air duct is located away from the burner to prevent the cool air entering the air duct from outside the stove from absorbing too much heat after passing through the burner, thus reducing the cooling efficiency of the fan.

[0014] Preferably, the angle range includes a first angle range. When the stop valve rotates to the first angle range, the stove is in a high-heat state. When the stove is in a high-heat state and maintains it for a preset time or a preset number of times, the controller issues a first command to start the fan.

[0015] Preferably, the fan includes a first fan and a second fan. When the stove is in a high-heat state and is maintained for a first preset time or a first preset number of times, the controller issues a first command to start the first fan.

[0016] When the stove is in high flame and is maintained for a second preset time or a second preset number of times, the controller issues a second command to start the second fan, wherein the second preset time or the second preset number of times is greater than the first preset time or the first preset number of times.

[0017] In this solution, when the stove is on high heat and maintained for a first preset time, the first fan is activated to cool down the electrical components that require priority cooling. When the stove is on high heat and maintained for a second preset time longer than the first preset time, the second fan is activated. The first and second fans work together to cool down the electrical components inside the stove, preventing them from overheating and aging or even causing danger.

[0018] Preferably, the preset angle range further includes a second angle range. When the stop valve rotates to the second angle range, the stove is in a medium-heat state. When the stove is in a medium-heat state and maintains it for a third preset time or a third preset number of times, the controller issues a third command to start the fan.

[0019] And / or, the preset angle range also includes a third angle range, the stop valve rotates to the third angle range corresponding to the stove being in a low flame state, the stove being in a low flame state and maintaining it for a fourth preset time or a fourth preset number of times, the controller issues a fourth command to start the fan.

[0020] In this solution, when the stove is in medium heat and maintained for a third preset time or a third preset number of times, the fan is activated to cool the internal electrical components. When the stove is in low heat and maintained for a fourth preset time or a fourth preset number of times, the fan is activated to cool the internal electrical components.

[0021] Preferably, the stove further includes an actuator for reducing or turning off the firepower of the stove. The controller is electrically connected to the actuator. When the timing module or counting module of the controller reaches a preset condition, it sends a command to the actuator to control the action of the actuator.

[0022] In this solution, when the stove is in a certain working state and meets preset conditions, the actuator is activated to reduce the stove's firepower or directly turn off the stove's firepower.

[0023] Preferably, the plug valve includes a valve core and a valve stem for rotating the valve core, and the actuator is used to drive the valve stem to rotate to adjust the rotation angle of the valve core.

[0024] In this solution, rotating the valve stem can adjust the rotation angle of the valve core within the valve body of the plug valve, thereby adjusting the gas flow rate into the burner, which can reduce or turn off the firepower of the stove.

[0025] Preferably, the stove is connected to a gas pipeline, and a gas valve is installed on the gas pipeline. The actuator is used to control the gas valve to adjust the gas intake flow rate.

[0026] In this solution, adjusting the gas valve can adjust the gas flow into the stove, thereby reducing or turning off the stove's heat.

[0027] Preferably, the stove is provided with operation buttons, which are electrically connected to the controller and are used to cause the controller to issue commands to the actuator.

[0028] In this solution, by setting operation buttons, a fire-off command can be manually sent to the controller, which can then reduce the stove's heat or turn it off via the actuator.

[0029] Preferably, the angle monitoring mechanism includes a trigger and a trigger switch. The trigger is mounted on the valve stem of the plug valve. When the trigger rotates with the plug valve into the preset angle range, the trigger can trigger the trigger switch to enable the controller to start the timing module or the counting module.

[0030] Preferably, the trigger element includes multiple trigger zones, which are spaced apart around the valve stem, and each trigger zone corresponds to an angle range; or,

[0031] The trigger switch is provided in multiple ways, and the multiple trigger switches are arranged circumferentially along the trigger element, with each trigger switch corresponding to an angle range.

[0032] In this design, the trigger switch connected to the controller functions similarly to a switch on the control circuit. By assigning a separate trigger switch to each angle range, the transmission of signals carrying firepower information is facilitated. When the trigger rotates to the corresponding angle range, the corresponding trigger switch closes, transmitting the signal carrying the firepower information to the controller. In other words, the controller's control circuit is configured to supply power only when the trigger switch is closed. The controller does not need to constantly monitor the trigger switch's status, which not only reduces the controller's computational load but also saves the stove's power consumption, thus conserving energy.

[0033] Alternatively, the trigger element can be designed to rotate through multiple angle ranges in one revolution, with different angle ranges corresponding to different firepower levels in the stove. Multiple trigger zones correspond to the same trigger switch. By differentiating the resistance values ​​of the trigger zones, the current signal generated by each trigger zone contacting the trigger switch is different, thus forming different angle range signals, allowing the controller to receive the rotation angle of the valve. This method of multiple trigger zones corresponding to one trigger switch reduces the design of circuitry, improves installation efficiency, and lowers installation costs.

[0034] Preferably, the trigger switch is a micro switch.

[0035] Preferably, the stove further includes an alarm module electrically connected to the controller, and the alarm module is configured to respond when the timing module or counting module of the controller reaches a preset alarm condition.

[0036] In this solution, when the controller's timing module or count module reaches the alarm condition, it indicates that the stove has exceeded the alarm time for the corresponding firepower level. The alarm module then responds to remind the user to adjust the stove's operating status. Specifically, the alarm module can be a buzzer alarm; when the timing module or count module exceeds the alarm condition, the buzzer alarm sounds.

[0037] The present invention also provides a method for controlling a stove, wherein the stove is as described above, and the control method includes the following steps:

[0038] S1. Monitor the rotation angle of the stopcock valve to determine the firepower status of the stove;

[0039] S2. Monitor the continuous working time of the stove under this firepower state;

[0040] S3. Compare the working time with the preset first time under the corresponding firepower state. If the working time exceeds the first time, start the cooling mechanism; if the working time is less than the first time, continue monitoring.

[0041] Preferably, step S3 includes:

[0042] S31. Compare the working duration with the preset second time corresponding to the firepower state. If the working duration exceeds the second time, activate the alarm module, wherein the second time is less than the first time.

[0043] The positive and progressive effects of this invention are as follows: the stove of this invention judges the firepower status of the stove by monitoring the rotation angle of the stopcock valve, and further monitors the duration of the stove in different firepower states according to the timing module or counting module of the controller to send a command to the actuator to start the cooling mechanism to cool down the electrical components inside the stove, thereby reducing the aging rate of the electrical components inside the stove and further reducing the danger of short circuit caused by the aging of electrical components.

[0057] Burner 700 Detailed Implementation

[0058] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0059] Example 1

[0060] This embodiment provides a stove, such as Figure 1 As shown, the appliance includes a stopcock valve 300, an angle monitoring mechanism, a cooling mechanism, and a controller 500. The angle monitoring mechanism monitors the rotation angle of the stopcock valve 300, and the cooling mechanism reduces the internal working temperature of the stove 100. The controller 500 is electrically connected to the angle monitoring mechanism and the cooling mechanism. The controller 500 is configured to activate a timing module or a counting module when the rotation angle of the stopcock valve 300 is within a preset angle range, and to send a command to the cooling mechanism to control its activation when the timing module or counting module of the controller 500 reaches a preset condition.

[0061] Working Principle: The firepower state of the stove 100 is determined by monitoring the rotation angle of the stopcock valve 300. Based on the duration of the stove 100 maintaining the same firepower state monitored by the timing module or count module of the controller 500, the controller 500 determines whether the duration of this firepower exceeds a preset condition. If the duration exceeds the preset condition, the controller 500 sends a command to the cooling mechanism to reduce the internal working temperature of the stove 100. The stove 100 of this invention will not operate for extended periods due to the user forgetting to turn off the stove, preventing the electrical components inside the stove 100 from being exposed to high temperatures for extended periods, which could lead to aging. This avoids short circuits caused by aging, thereby improving the safety of the stove 100 during use.

[0062] The stove 100 of the present invention can set corresponding preset cooling conditions according to different firepower levels. For example, if the stove 100 operates at high firepower for one hour, the controller 500 sends a signal to the cooling mechanism to cool the electrical components inside the stove 100; if the stove 100 operates at medium firepower for two hours, the controller 500 sends a signal to the cooling mechanism to cool the electrical components inside the stove 100. As another example, if the stove operates at high firepower for one hour, the controller sends a signal to the cooling mechanism to cool the stove.

[0063] In this embodiment, the cooling mechanism includes a fan. The fan's air inlet is connected to the outside of the stove 100. The stove 100 has an internal air duct. One end of the air duct opens towards the electrical components inside the stove 100, and the fan's air outlet is connected to the other end of the air duct. The fan cools the electrical components by being installed inside the stove 100. When the fan is started, cool air from outside the stove 100 enters through the fan inlet, flows from one end of the air duct connected to the fan outlet to the other end, and then flows to the surface of the electrical components, carrying away the surface temperature and cooling the components.

[0064] In other embodiments, the opening at the air outlet of the air duct is aligned with the knob 600 on the cooktop 100, which can reduce the temperature at the knob 600. This prevents the knob 600 from becoming too hot and burning the user's hands when operating it.

[0065] In other embodiments, the opening at the air outlet of the duct is opposite to the panel of the cooktop 100. After prolonged high-heat cooking, the panel temperature of the gas stove can easily rise, potentially causing the glass panel to shatter. Therefore, when the cooktop is in high-heat mode for an extended period, activating the fan allows cool air from outside the cooktop 100 to pass through the duct and blow onto the panel, cooling it and preventing it from overheating and shattering, thus avoiding a potential hazard.

[0066] In other embodiments, the air outlet of the air duct is configured to be movable, which can improve the airflow within the stove 100 and improve cooling efficiency.

[0067] In other embodiments, the cooling mechanism includes a liquid cooling device disposed within the cooktop 100, which, when activated, cools the interior of the cooktop 100. If necessary, the liquid cooling device can be wound around the component within the cooktop 100 that requires the most cooling, thereby improving cooling efficiency.

[0068] The cooktop 100 also includes a burner 700. The air duct is located away from the burner 700 to prevent the cool air entering the air duct from outside the cooktop 100 from absorbing too much heat after passing through the burner 700, thus reducing the cooling efficiency of the fan.

[0069] The aforementioned angle range includes a first angle range. When the stopcock valve 300 rotates to the first angle range, the stove 100 is in a high-heat state. When the stove 100 is in a high-heat state and remains so for a preset time or number of times, the controller 500 issues a first command to start the fan. For example, when the stopcock valve 300 rotates 140-160 degrees from its initial state, the stove 100 is in a high-heat state. After the stove remains in a high-heat state for one hour, the controller issues a command to start the fan to cool the stove.

[0070] The fan system includes a first fan 410 and a second fan 420. When the stove 100 is in a high-heat state and maintained for a first preset time, the first fan 410 is activated to cool the electrical components that require priority cooling. When the stove 100 is in a high-heat state and maintained for a second preset time longer than the first preset time, the second fan 420 is activated. The first fan 410 and the second fan 420 simultaneously cool the electrical components inside the stove 100, preventing the components from overheating and aging or even causing danger. In this embodiment, for example, after the stove 100 has been operating in a high-heat state for one hour, the first fan 410 is activated to cool the stove 100. After the stove 100 has been operating in a high-heat state for two hours, the second fan 420 is activated. At this time, the first fan 410 and the second fan 420 operate simultaneously, which can improve the efficiency of cooling the stove 100. In other embodiments, after the stove 100 has been operating in a high-heat state for half an hour, the first fan 410 is activated to cool the stove 100. After the stove 100 is in high heat for one hour, the second fan 420 and the first fan 410 are started simultaneously to cool down the stove 100.

[0071] The aforementioned angle range also includes a second angle range. When the stopcock valve 300 rotates to the second angle range, the stove 100 is in a medium-heat state. When the stove 100 is in a medium-heat state and maintains this state for a third preset time or a third preset number of times, the controller 500 issues a third command to start the fan. For example, when the stopcock valve 300 rotates 80-140 or 160-220 degrees from its initial state, the stove 100 is in a medium-heat state. In this embodiment, the stove 100 is kept in a medium-heat state for one and a half hours before the fan is started to cool the stove 100. In other embodiments, the stove 100 is kept in a medium-heat state for one hour before the fan is started to cool the stove 100.

[0072] The angle range also includes a third angle range. When the stopcock valve 300 rotates to the third angle range, the stove 100 is in a low-heat state. When the stove 100 is in a low-heat state and maintains this state for a fourth preset time or a fourth preset number of times, the controller 500 issues a fourth command to start the fan. For example, when the stopcock valve 300 rotates 20-80 or 220-240 degrees from its initial state, the stove 100 is in a low-heat state. In this embodiment, after the stove 100 maintains a low-heat state for one and a half hours, the fan is started to cool the stove 100. In other embodiments, after the stove 100 maintains a low-heat state for one hour, the fan is started to cool the stove 100.

[0073] As described above, in this embodiment, when the valve stem 310 of the stopcock valve 300 rotates clockwise or counterclockwise, the stove is in the off state within the range of 0-20 degrees, in the low flame state within the range of 20-80 degrees, in the medium flame state within the range of 80-140 degrees, in the high flame state within the range of 140-160 degrees, in the medium flame state within the range of 160-220 degrees, in the low flame state within the range of 220-240 degrees, and in the off state within the range of 240-360 degrees.

[0074] The cooktop 100 is equipped with operation buttons (not shown in the figure), which are electrically connected to the controller 500. The operation buttons are used to send commands from the controller 500 to the actuator. By setting the operation buttons to send a flame-off command to the controller 500, the actuator can be used to reduce the flame of the cooktop 100 or turn it off. The operation buttons can also be used to cancel the sound emitted by the alarm module.

[0075] like Figure 2 As shown, the angle monitoring mechanism includes a trigger element 210 and a trigger switch 220, as... Figure 2 As shown, the trigger element 210 is mounted on the valve stem 310 of the plug valve 300. When the trigger element 210 rotates with the plug valve 300 to a preset angle range, it can trigger the trigger switch 220 to activate the timing module or the counting module of the controller 500. The arc angle range of the trigger element is the same as the angle range of the plug valve corresponding to the high-fire zone; that is, the shape of the trigger element is determined by the position and angle range of the high-fire zone. Therefore, the shape of the trigger element is not limited to the following. Figure 2 The arc-shaped block structure shown can also be other shapes.

[0076] In this embodiment, the trigger 210 is abutted against the valve body by a snap ring to restrict its vertical movement on the valve 310, preventing the trigger 210 from moving vertically on the valve stem 310 when the valve stem rotates, thus preventing it from triggering the trigger switch 220. In other embodiments, the trigger 210 can be directly welded to the valve stem 310. The trigger 210 is typically made of metal to facilitate welding it to the valve stem 310. Rubber is wrapped around the area where the trigger 210 contacts the trigger switch 220 to protect the trigger switch 220.

[0077] In this embodiment, when monitoring the operating time of the stove in medium or low heat mode, multiple trigger zones can be set on the trigger element 210. These trigger zones are spaced around the valve stem 310, with each trigger zone corresponding to an angle range. Multiple trigger zones correspond to the same trigger switch 220, and one rotation of the trigger element 210 corresponds to passing through multiple angle ranges. For example, by setting different sensors in different trigger zones, each sensor in a trigger zone contacts the trigger switch 220, corresponding to a different angle range signal, allowing the controller to receive information about the rotation angle of the stopcock valve 300 to obtain the stove's heat status. In other embodiments, photoelectric sensors are used to identify the trigger zones of the trigger element 210, with each trigger zone corresponding to a different photoelectric signal, thereby determining the rotation angle of the stopcock valve 300.

[0078] In this embodiment, the trigger switch 220 is a micro switch. The controller's control circuit is configured to supply power only when the micro switch is closed. The controller does not need to constantly monitor the state of the micro switch; power is only supplied to the control circuit when the micro switch is closed. When the micro switch is closed, there is no action, further saving power. In this embodiment, the micro switch is closed when the stove is in high heat.

[0079] In other embodiments, multiple trigger switches 220 are provided, arranged circumferentially along the trigger member 210, with each trigger switch 220 corresponding to an angle range. The trigger switches 220 are connected to the controller 500, functioning as switches on the control circuit. When a trigger switch 220 is closed, the controller's timing module is activated. By assigning a separate trigger switch 220 to each angle range, the transmission of signals carrying firepower information is facilitated. When the trigger member 210 rotates to the corresponding angle range, the corresponding trigger switch 220 closes, transmitting the signal carrying firepower information to the controller 500. That is, the controller 500's control circuit is configured to provide power only when the trigger switch 220 is closed. The controller 500 does not need to continuously monitor the state of the trigger switch 220, reducing the computational load on the controller 500 and saving power for the stove 100, thus conserving energy. In other embodiments, the trigger switch 220 can also be configured to activate the controller's timing module when it is open.

[0080] like Figure 3 As shown, the stove 100 also includes an alarm module electrically connected to the controller 500. The alarm module is configured to respond when the timing module or count module of the controller 500 reaches a preset alarm condition. When the timing module or count module of the controller 500 reaches the alarm condition, it indicates that the stove 100 has been operating at the corresponding heat level for a longer period than the alarm time, reminding the user to adjust the heat level of the stove 100 or turn off the stove. For example, the alarm module can be a buzzer alarm; after the timing module or count module exceeds the alarm condition, the buzzer alarm sounds. In this embodiment, if the stove 100 operates at high heat for one hour, the alarm module responds and sounds an alarm to remind the user that the stove has been operating at high heat for an extended period, which may be dangerous. At this time, the user can choose to turn off the alarm module or activate the cooling mechanism. If the user does not perform any operation, after monitoring that the stove continues to operate at high heat for a certain period of time (e.g., ten minutes), the controller sends a signal to the cooling mechanism to cool the stove.

[0081] The stove 100 of this invention can improve safety during long-term operation. For example... Figure 3 As shown, when the controller 500 detects that the user has started the stove 100 for cooking, it first determines the firepower of the stove 100 based on the rotation angle of the stopcock valve 300. If the controller 500 detects that the stove 100 has been operating continuously under the same firepower condition for more than a first preset time, it will first issue a reminder signal to the user. The user must silence the alarm sound to confirm that they are monitoring the operation of the stove 100. If the user does not silence the alarm sound, and the stove continues to operate at that firepower level for a certain period of time (e.g., ten minutes), the controller 500 will send a command to the cooling mechanism to cool the stove 100.

[0082] This embodiment also provides a method for controlling a stove, the stove being the one described above, and the control method includes the following steps:

[0083] S1. Monitor the rotation angle of the stopcock valve to determine the firepower status of the stove;

[0084] S2. Monitor the continuous working time of the stove under this firepower state;

[0085] S3. Compare the working time with the preset first time under the corresponding firepower state. If the working time exceeds the first time, start the cooling mechanism; if the working time is less than the first time, continue monitoring.

[0086] Step S3 includes:

[0087] S31. Compare the working duration with the preset second time corresponding to the firepower state. If the working duration exceeds the second time, activate the alarm module, wherein the second time is less than the first time.

[0088] In other embodiments, an alarm module may not be provided. When the controller 500 detects that the user has started the stove 100 for cooking, it first determines the firepower of the stove 100 based on the rotation angle of the stopcock valve 300. After the controller 500 detects that the stove 100 has been working continuously under the same firepower condition for more than a first preset time, the controller 500 directly sends a command to the cooling mechanism to cool down the stove 100.

[0089] This embodiment determines the firepower of the stove 100 by monitoring the rotation angle range of the trigger 210. The use of a cooling mechanism, an angle monitoring mechanism, and a controller provides a safer and more comfortable cooking method.

[0090] In some embodiments, the cooktop 100 further includes an actuator for adjusting or turning off the heat of the cooktop 100. A controller 500 is electrically connected to the actuator. When a preset condition is met by the timing module or counting module of the controller 500, a command is sent to the actuator to control its operation. The heat state of the cooktop 100 is determined by monitoring the rotation angle of the stopcock valve 300. Based on the duration of different heat states monitored by the timing module or counting module of the controller 500, the controller 500 determines whether the duration exceeds a preset condition. If the duration exceeds the preset condition, the controller 500 sends a command to the actuator to adjust or turn off the heat of the cooktop 100.

[0091] By incorporating the aforementioned actuator, the stove 100 will not operate for extended periods due to the user forgetting to turn it off, thus reducing the possibility of fire and improving the safety of the stove 100. The plug valve 300 includes a valve core and a valve stem 310 that rotates the valve core. The actuator drives the valve stem 310 to rotate, adjusting the rotation angle of the valve core. The actuator and the cooling mechanism can be activated simultaneously, or either the cooling mechanism or the actuator can be activated first.

[0092] Rotating the valve stem 310 can adjust the rotation angle of the valve core within the valve body of the plug valve 300, thereby adjusting the gas flow rate into the burner, which can reduce or turn off the firepower of the stove 100.

[0093] The stove 100 is connected to a gas pipeline, and a gas valve is installed on the gas pipeline. In other embodiments, the gas valve is a solenoid valve, and the actuator is a solenoid valve or a mechanism that controls the solenoid valve. The gas supply to the stove 100 is controlled by opening and closing the solenoid valve. When the solenoid valve is energized, gas can enter the stove. A reverse voltage can be used to disconnect the solenoid valve, thus cutting off the gas supply and turning off the stove.

[0094] In other embodiments, the cooktop 100 also includes a linkage device electrically connected to the controller 500. The linkage device is connected to the range hood. When the controller 500 reaches a preset condition, the controller 500 activates the linkage device to increase the power of the range hood.
