Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.
Referring to fig. 1 and fig. 2, to achieve the above object, a first embodiment of the present invention provides a heating control method applied to a heating control system of an electric heating appliance, where the heating control system includes a control unit 10, and the control unit 10 is electrically connected to a heating unit 20 of the electric heating appliance; the heating control method comprises the following steps:
step S10, acquiring the times of heating signals received by the heating unit and the times of heating signal cancellation within a first set time;
and step S20, when the number of times of the heating signal reaches the first set number of times and the number of times of the heating signal cancellation reaches the second set number of times, controlling the heating unit to stop heating.
In the technical scheme of the invention, the heating control method obtains the number of times of the heating signal received by the heating unit 20 and the number of times of the heating signal cancellation within a first set time, when the number of times of the heating signal reaches the first set number of times and the number of times of the heating signal cancellation reaches the second set number of times, the electric heating appliance reaches or approaches an overheating state, and at the moment, the heating unit 20 is controlled to stop heating, which is beneficial to solving the defect that the overheating state caused by the heating unit 20 entering the heating state and canceling the heating state for multiple times within a certain time cannot be avoided.
Since the initial temperature of the electric heating device is low when the electric heating device enters the heating state from the power-on state, the heating unit 20 will heat in the full power state in a short time after receiving the heating signal, so as to realize the rapid temperature increase. At this time, if the heating is canceled and the heating unit 20 is rapidly brought into the heating state again, and the operations of heating, canceling heating, and reentering heating are repeated a plurality of times, the electric heating appliance is brought into the overheat state in a short time, and therefore, the number of times the heating unit 20 is brought into the heating and the number of times the heating is canceled within the set time are determined, and the temperature value section of the electric heating appliance within the set time is obtained, and based on the temperature value section, it is possible to determine whether the electric heating appliance is brought into or close to the overheat state.
The first set time is usually a short time within which heating and removing of the electric heating appliance are performed a plurality of times, which may cause an overheat state of the electric heating appliance. The first set time may be set as needed, and may be, for example, 1 minute to 5 minutes.
In the first setting time, the part to be heated of the electric heating appliance can be increased to different temperature values according to different times of starting the heating process by the heating unit 20, and the temperature value of the electric heating appliance can be increased to an overheating range only after the heating times and the heating canceling times are determined according to experimental tests, so that the first setting times and the second setting times can be determined according to the tests.
Further, the first set number of times and the second set number of times are also related to the heating power of the electric heating appliance and the current room temperature, since the power of the electric heating appliance is determined, a mapping relation table of the first set number of times, the second set number of times and different room temperatures can be established in advance, the heating control method can further obtain the current room temperature, and the first set number of times and the second set number of times can be determined according to the current room temperature and the mapping relation table.
When the number of times of the heating signal reaches the first set number of times and the number of times of canceling the heating signal reaches the second set number of times, no matter whether the heating unit 20 receives the heating signal or the canceling the heating signal for the last time, the heating unit 20 is controlled to stop heating the part to be heated of the electric heating appliance, so that the electric heating appliance is rapidly cooled.
The electric heating appliances are not limited in type, and can be electric cooking appliances such as electric kettles, electric cookers, induction cookers and the like, and can also be industrial electric heating devices. For convenience of description, the electric heating device is exemplified by an electric cooker, and the electric heating device may be heated by electromagnetic heating.
The first set number and the second set number are different in consideration of the difference in actual power of the electric heating appliance. For example, since the electric cooker has a low power, when the electric heating appliance is an electric cooker, the first set number and the second set number are preferably 50 to 200 times, respectively. For example, the first set time may be 3 minutes, and the first set number of times and the second set number of times may be 150 times, respectively.
Referring to fig. 3, based on the first embodiment of the heating control method of the present invention, in the second embodiment of the heating control method of the present invention, the heating control system further includes a temperature detecting unit 30 electrically connected to the control unit 10, wherein the temperature detecting unit 30 is configured to detect a temperature value of a member to be heated of the electric heating appliance; the step S20 specifically includes:
step S21, when the number of times of the heating signal reaches a first set number of times and the number of times of the heating signal cancellation reaches a second set number of times, acquiring the temperature value detected by the temperature detection unit;
and step S22, controlling the heating unit to stop heating when the temperature value reaches the set temperature value.
Different room temperatures and different operation time intervals have certain influence on the temperature rise value of the electric heating appliance, so that when the times of the heating signals reach the first set times and the times of canceling the heating signals reach the second set times, the temperature value of the part to be heated of the electric heating appliance can be further detected, and particularly, the temperature value of the heated part of the part to be heated can be directly detected. Only when the temperature value reaches the set temperature value, the heating unit 20 is controlled to stop heating the part to be heated of the electric heating appliance, so that the situation that the user experience is reduced due to the fact that the electric heating appliance does not reach the overheating state but stops heating is avoided. The temperature value detected by the temperature detecting unit 30 may specifically be a temperature value of a heated portion of the to-be-heated member, for example, a pot bottom temperature value of an electric rice cooker.
The set temperature value can be set as required, in this embodiment, the set temperature value can be determined according to the fuse fusing temperature of the temperature detection unit 30, and further, the set temperature value is preferably smaller than the fuse fusing temperature, so as to avoid damaging the temperature detection unit 30.
After step S21, the method may further include: and when the temperature value does not reach the set temperature value, detecting whether the current time reaches a first set time, and if not, continuously acquiring the times of heating signals and the times of canceling the heating signals. When the first set time is increased by a third set time (for example, every 10 times), and when the second set time is increased by a fourth set time (for example, every 10 times), the temperature value of the part to be heated of the electric heating appliance is detected again, whether the temperature value reaches the set temperature value is judged, if yes, the heating unit is controlled to stop heating, and if not, the times of acquiring the heating signal and the times of canceling the heating signal are continuously acquired until the timing time reaches the first set time.
Further, referring to fig. 4, based on the second embodiment of the heating control method of the present invention, in the third embodiment of the heating control method of the present invention, after the step S22, the method further includes:
and step S30, when the time for stopping heating reaches a second set time and the signal received by the heating unit for the last time at the end of the second set time is the heating signal, controlling the heating unit to enter a normal heating mode.
The first set number of times and the second set number of times may be equal to indicate that the current heating signal is cancelled, i.e., the heating unit is in a heating stop state; the first set number of times may also be one more than the second set number of times to indicate that the heating signal is not cancelled, i.e. that the heating unit is in a heating state.
And when the signal received by the heating unit 20 for the last time at the end of the second set time is a heating signal, controlling the heating unit 20 to enter a normal heating mode, which is equivalent to performing time delay operation on the last heating signal so as to reduce the temperature of the part to be heated within a safe range within the time delay, and then heating, thereby ensuring that the heating process of the whole electric heating appliance is safely performed.
Further, in a third embodiment of the heating control method of the present invention, the heating control method further includes:
when the heating unit 20 enters the normal heating mode, the temperature value of the part to be heated of the electric heating appliance is detected in real time, specifically, the temperature value of the heated part of the part to be heated, for example, the temperature value of the bottom of the pot of the electric cooker, is detected in real time, so that the temperature detecting unit 30 also enters the normal temperature detecting mode.
Referring to fig. 5, based on the third embodiment of the heating control method of the present invention, in the fourth embodiment of the heating control method of the present invention, the step S30 specifically includes:
step S31, detecting whether the time for stopping heating reaches a second set time;
if yes, go to step S32: detecting whether the signal received by the heating unit for the last time is the heating signal or not when the second set time is over;
when the signal received by the heating unit for the last time is the heating signal, executing step S33: detecting whether the part to be heated is at a position to be heated;
when the member to be heated is at the position to be heated, step S34 is executed: controlling the heating unit to enter a normal heating mode.
When the second set time is over and the last received signal of the heating unit 20 is a heating signal, the fourth embodiment of the heating control method of the present invention further needs to detect whether the part to be heated is at the position to be heated, and when the electric heating appliance is an electric cooker, the part to be heated is a pot, the position to be heated of the part to be heated refers to the position to be heated of the pot, and the normal heating mode is a normal cooking mode (for example, a rice cooking mode or a porridge cooking mode). The heating button has been pressed in the discovery, and when electric rice cooker did not heat, whether the user probably can take out the pan of electric rice cooker and observe the electromagnetic heating part normal, but not necessarily can in time install the pan back to the position of waiting to heat, at this moment, if confirm through the detection that the pan is in after waiting to heat the position, the re-control heating unit 20 gets into normal heating mode, can make the heating process more safe and reliable. Further, the heating control method can further detect whether the part to be heated is in a dry-fire state on the basis of the heating control method.
Further, in this embodiment, after step S32, the method further includes:
when the last received signal of the heating unit is not the heating signal (i.e., the last received signal is a heating cancellation signal), step S35 is executed to control the heating unit to exit the heating mode.
Referring to fig. 6, based on any one of the first to fourth embodiments of the heating control method of the present invention, in a fifth embodiment of the heating control method of the present invention, the heating control system further includes a timer unit, a first counter unit, and a second counter unit;
before the step S10, the method further includes:
and step S40, clearing the timing data of the timer unit, and clearing the count data of the first counter unit and the second counter unit.
The first counter is used for recording the number of times of the heating signal received by the heating unit in the timing time period of the timer unit, and the second counter is used for recording the number of times of the heating canceling signal received by the heating unit in the timing time period of the timer unit.
And step S50, when the heating signal is received for the first time or the heating signal is cancelled, assigning a first set time of the timer unit and starting timing.
Before the step S10, the heating control method may further include a step of performing an initialization operation on the heating control system, and the step S40 may be provided in the step of the initialization operation.
Specifically, the initialization operation may be performed immediately after the electric heating appliance is powered on, or may be performed after any control step other than the detection and cancellation of the heating control after the power-on. The initialization operation may specifically include turning off the heating system, clearing the first timer timing data (making T0 equal to 0), and clearing the count data of the first counter (for counting the heating signal) (making Time0 equal to 0) and the count data of the second counter (for counting the cancel heating signal) (making Time1 equal to 0).
Further, after step S40, it may be further determined whether the counted time T0 of the first timer has decreased to 0, if so, step S10 and step S20 may be started, and if not, the counted time T0 may be automatically decreased to 0.
When a first heating control signal (the first heating control signal may be a heating signal or a heating canceling signal, based on a signal for performing heating control for the first Time) is received, whether the first timer T0 counts Time to 0 is determined, if yes, a first set Time is assigned to the first timer T0, the times of receiving the heating signal and canceling the heating signal are counted, whether Time0 reaches the first set Time or not is detected, and whether Time1 reaches a second set Time or not is detected.
When the first timer T0 counts Time not exceeding a first set Time (e.g., 180s here), and when Time0 reaches a first set number of times (e.g., 150 times here), Time1 reaches a second set number of times (e.g., 150 times here), the heating unit 20 may be controlled to stop heating; further, when the Time counted by the first timer T0 does not exceed the first set Time, and when the Time0 reaches the first set Time and the Time1 reaches the second set Time, it may further detect whether the temperature value of the bottom of the pot reaches the set temperature value (for example, it may be 150 ° here), and if so, control the heating unit 20 to stop heating, and start the second timer to start counting.
When the time counted by the second timer (i.e. the heating stop time) reaches a second set time (e.g. 10s), if the heating control signal received by the heating unit 20 last time is the heating signal, the operation of detecting whether the heating component is at the position to be heated is turned on, for example, the heating control system is turned on to detect the operation of the pot to determine whether the pot is at the position to be heated. When the heating stop time reaches the second set time (here, 10s), if the heating control signal received by the heating unit 20 for the last time is the heating cancel signal, the heating unit 20 is controlled to exit the heating mode.
When the part to be heated is located at the position to be heated, the heating unit 20 is controlled to enter a normal heating mode, the part to be heated is subjected to continuous heating control, and the temperature detection unit 30 is controlled to detect the temperature value of the part to be heated in real time.
Referring to fig. 7, based on the fifth embodiment of the heating control method of the present invention, in the sixth embodiment of the heating control method of the present invention, the heating control method further includes:
step S60, when it is detected that the count data of the timer unit reaches the first set time, controlling the count data of the timer unit to be cleared, and controlling the count data of the first counter unit and the second counter unit to be cleared.
When the timing time of the first timer T0 reaches the first set time, the data of the first timer, the first counter and the second counter are cleared to wait for a new round of heating control.
In order to achieve the above object, the present invention further provides a heating control system for controlling heating of an electric heating appliance, the heating control system including: a memory, a control unit 10, a computer program stored on said memory and executable on said control unit 10, and a heating unit 20 electrically connected to said control unit 10; the computer program realizes the steps of the heating control method according to any one of the first to sixth embodiments when executed by the control unit 10.
Further, the heating unit 20 in the heating control system may obtain the heating signal and cancel the heating signal in various ways.
Referring to fig. 8, the heating control system includes a first control circuit and a second control circuit; a first current limiting resistor 60(R1) is connected in series to the first control circuit, one end of the first control circuit is grounded, the other end of the first control circuit is connected in series to a heating start switch capable of conducting the first control circuit and the control unit 10, and when the first control circuit is conducted with the control unit 10, the heating unit 20 receives the heating signal; the second control circuit is connected in series with a second current limiting resistor 70(R2), one end of the second control circuit is grounded, the other end of the second control circuit is connected in series with a heating canceling switch capable of conducting the second control circuit and the control unit 10, and when the second control circuit is conducted with the control unit 10, the heating unit 20 receives a heating canceling signal.
When the heating signal is acquired and the heating signal is canceled in this way, the step S10 specifically includes:
step S11, acquiring the conducting times of the first control circuit and the control unit in a first set time, and determining the conducting times of the first control circuit and the control unit as the times of the heating signal;
step S12, acquiring the number of times that the second control circuit and the control unit are conducted within a first set time, and determining the number of times that the second control circuit and the control unit are conducted as the number of times of the heating canceling signal.
When the heating signal and the heating canceling signal are obtained in this way, two heating function control switches may be provided on the control panel of the electric heating appliance, and the switches may be provided in the form of keys, one of which is the start heating key 40 and the other of which is the heating canceling key 50. When the heating key 40 is operated, the first control circuit is conducted with the control unit 10, and when the heating key 50 is operated, the second control circuit is conducted with the control unit 10. Therefore, by acquiring the number of times the heating start key 40 is operated, the number of times the first control circuit is conducted with the control unit 10 can be determined, thereby further determining the number of times the heating signal is conducted; by acquiring the number of times the heating-canceling key 50 is operated, the number of times the second control circuit is turned on with the control unit 10 can be determined, thereby further determining the number of times the heating-canceling signal is canceled.
Or, the heating signal and the heating canceling signal may be acquired in such a manner that, when the heating control system is connected to the power supply, the heating unit 20 receives the heating signal, and when the heating control system is disconnected from the power supply, the heating unit 20 receives the heating canceling signal;
when the heating signal is acquired and the heating signal is canceled in this way, the step S10 specifically includes:
step S13, acquiring the connection times of the heating control system and the power supply within a first set time, and determining the connection times of the heating control system and the power supply as the times of the heating signal;
and step S14, acquiring the disconnection times of the heating control system and the power supply within a first set time, and determining the disconnection times of the heating control system and the power supply as the times of canceling the heating signal.
Some electric heaters directly enter a heating state when being powered on, and directly cancel the heating state when being powered off, thereby being capable of not setting a heating control key. For this type of electric heating appliance, the number of times of the heating signal and the number of times of the heating signal cancellation may be determined by acquiring the number of times of connection and disconnection of the heating control system to the power source within a first set time.
Alternatively, the heating signal and the heating canceling signal may be obtained by a manner that the heating control system includes a heating control key, the heating unit 20 receives one of the heating signal and the heating canceling signal when the heating control key is operated for an odd number of times, and the heating unit 20 receives the other of the heating signal and the heating canceling signal when the heating control key is operated for an even number of times.
When the heating signal is acquired and the heating signal is canceled in this way, the step S10 specifically includes:
s15, acquiring the times of the heating control key being operated for odd times within a first set time, and acquiring the times of the heating control key being operated for even times within the first set time;
and S16, determining the times of the heating signals and the times of the heating signal cancellation according to the odd operation times and the even operation times.
Some electric heating appliances are only provided with one heating control key, when the heating control key is operated for odd times, the bottom of a pot of the electric heating appliance is heated, and when the heating control key is operated for even times, the bottom of the pot of the electric heating appliance is not heated; in addition, the electric heating appliance provided with only one heating control button may be configured to heat the pot bottom of the electric heating appliance when the heating control button is operated even number of times, and to cancel heating of the pot bottom of the electric heating appliance when the heating control button is operated odd number of times.
For both types of electric heating appliances, the number of times the heating control key is operated odd number of times and the number of times the heating control key is operated even number of times may be counted, respectively, to determine the number of times the heating signal is applied and the number of times the heating signal is canceled.
