Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a view of an application scenario provided by an embodiment of the present invention, as shown in fig. 1, when a pot is heated on an electromagnetic appliance, such as an electromagnetic oven, a dry-cooking condition of the pot may occur, for example, a user forgets that the electromagnetic oven is heating the pot and does not detect the pot on the electromagnetic oven for a long time, or the user forgets to add water to the pot and then places the pot on the electromagnetic oven for heating.
Among the prior art, detect the temperature of pan through temperature sensor, judge whether the pan is done or not and burn, but, because the temperature that temperature sensor detected has the hysteresis quality, when the temperature that detects through temperature sensor confirms that the pan is done and burns, the pan has actually done and burns for a period to eat the material damage in leading to the pan, and high temperature also can lead to the electromagnetism stove to appear damaging.
Wherein, the principle of electromagnetic utensil heating does: the coil in the electromagnetic appliance generates a magnetic field, and when the magnetic force line emitted by the magnetic field contacts the metal pot, the magnetic field can react with the metal. When the pot and the magnetic force lines interact, the magnetic force lines cut the molecules in the metal to make it generate random violent movement. At this time, the metal molecules collide with each other to gradually generate heat, and the temperature of the pot is rapidly increased, so that cooking can be realized. The magnetic field generated by the coil is generated by turning on and off an Insulated Gate Bipolar Transistor (IGBT), and the on duration of the IGBT is determined by the on width (PPG) of the IGBT output by the control module of the electromagnetic device. The heating power of the electromagnetic appliance is therefore related to the size of the PPG. Therefore, the present invention detects whether the pot on the induction cooker is dry-burned according to the heating power of the electromagnetic appliance and the PPG, and is detailed in the following method embodiments.
Moreover, when the pot is dry-boiled, the temperature of the pot is rapidly raised, the heating power of the electromagnetic appliance is directly reduced, and the PPG is directly increased after the heating power is reduced. Therefore, whether the electromagnetic appliance is dry-burned or not can be detected in time according to the heating power and the PPG.
Fig. 2 is a flowchart of a pot dry-cooking detection method according to an embodiment of the present invention, where the pot dry-cooking detection method is applied to an electromagnetic appliance, as shown in fig. 2, the method of the embodiment may include:
s101, obtaining the current conducting width PPG and the current heating power of the IGBT of the electromagnetic appliance.
In the present embodiment, an electromagnetic device is described by taking an electromagnetic oven as an example. The electromagnetic oven is provided with a constant power control program, and when the electromagnetic oven normally heats the cooker, the electromagnetic oven controls the heating power to heat constantly with the set heating power through the constant power control program. That is, when the heating power is greater than the set heating power, the constant power control program reduces the PPG output; when the heating power is less than the set heating power, the constant power control program increases the PPG output. When the pot on the induction cooker is dried, the heating power of the induction cooker is reduced, so that the PPG output is increased by the constant power control program; or when the PPG reaches the maximum PPG of the IGBT when the induction cooker is normally heated at low power, if the cooker is dry-burned, the heating power is kept unchanged by increasing the PPG, and therefore the heating power is reduced. Therefore, the induction cooker can detect whether the cookware heated on the induction cooker is dry-burned or not according to the current heating power and the current PPG.
The induction cooker may, for example, periodically detect whether the torch is dry-burned, for example, the current PPG and the current heating power are acquired every 2 s. Or, different cooking functions require different requirements for detecting dry cooking of the pot, and a detection period is set according to the current cooking function of the induction cooker, for example, when the induction cooker is used for cooking, the detection period can be 1s because the water content in the pot is less, and the detection period can be 4s when soup is cooked or water is boiled. The specific data can be set according to actual conditions, and the application is not limited to the specific data.
S102, detecting whether the cookware heated by the electromagnetic appliance is dry-cooked or not according to the current PPG and the current heating power.
In this embodiment, optionally, after the current PPG and the current heating power are acquired, the cache PPG and the cache heating power are acquired. Wherein, when detecting whether the pan is dry to burn at every turn, when the heating power who obtains is greater than cache power, with cache heating power replacement for current heating power to and with cache PPG for current PPG. Therefore, the heating power and the PPG can be prevented from being stored when the induction cooker is just started and the heating power is in a rising stage, and at the moment, the heating power and the PPG do not reach stable values yet. When the pot is dry-burned, the heating power is reduced from a stable value, the PPG is increased, the current heating power can be used for de-culturing the cache heating power, and the current PPG is larger than the cache PPG. Therefore, when the current heating power is larger than the cache power, the cache heating power is replaced by the current heating power, and the cache PPG is replaced by the current PPG, so that the detection accuracy can be improved. Or if the cookware is not dried, replacing the cache heating power with the current heating power, and replacing the cache PPG with the current PPG.
And then comparing the current PPG with the cache PPG, comparing the current heating power with the cache heating power, and acquiring the change trend of the current PPG and the current heating power so as to detect whether the cookware is dry-burned.
When detecting the pan dry combustion method through the electromagnetism stove heating, control electromagnetism stove stop heating, perhaps intermittent type heating, or reduce heating power, for example with minimum heating power heating, avoid suffering the damage because of the electromagnetism stove lasts the heating and leads to the edible material in the pan to and the pan dry combustion method produces high temperature transmits the electromagnetism stove after, the electromagnetism stove breaks down.
In the embodiment, the current on-width PPG and the current heating power of the IGBT of the electromagnetic appliance are obtained; according to the current PPG and the current heating power, whether the cookware heated by the electromagnetic appliance is dry-burned or not is detected. When the cookware is dried, the temperature rises rapidly, and the raised temperature is within the temperature range when the cookware is not heated normally any more, so that the balance between the original cookware and the magnetic field is destroyed rapidly. Therefore, when the pot is dry-burned, the heating power of the electromagnetic appliance and the PPG value can be rapidly changed. Therefore, compared with the temperature detected by the temperature sensor, the heating power and the PPG can quickly and accurately detect whether the cookware is dry-burned or not, and the safety of the electromagnetic appliance is improved.
The technical solution of the embodiment of the method shown in fig. 1 will be described in detail below by using several specific examples.
Fig. 3 is a flowchart of a pot dry-cooking detection method according to another embodiment of the present invention, as shown in fig. 3, the method of the present embodiment may include:
s201, judging whether the current heating power is smaller than or equal to the cache heating power, if so, executing S202; if not, executing S204;
in the embodiment, the heating power is reduced due to dry burning of the cookware, the constant power control program is arranged in the electromagnetic oven, and when the heating power begins to be reduced, the PPG is increased through the constant power control program to keep the heating power unchanged. However, if the heating power is continuously decreased, the heating power cannot be maintained by increasing the PPG. Therefore, if the current heating power and the current PPG are obtained when the cooker is in dry burning, the current heating power is smaller than or equal to the heating power.
However, when the pot is not dry-burned, the heating power of the induction cooker is also kept unchanged, so if the current heating power is less than or equal to the cache heating power, the pot may be dry-burned, and S202 needs to be executed to further determine whether the pot is dry-burned; if the current heating power is larger than the cache heating power, the cookware is not dried.
S202, judging whether the difference value of the current PPG minus the cache PPG is larger than or equal to a first preset value, if so, executing S203; if not, executing S204;
in this embodiment, when the pot is dry-boiled, the heating power is kept as constant as possible by increasing the PPG in the constant power control program. Therefore, if the pot is burned, PPG increases. And judging whether the difference value of the current PPG minus the cached PPG is greater than or equal to a first preset value. Wherein, because differences such as pan material, size, for example can set up different first default according to the pan of difference. If the difference value of the current PPG and the cached PPG is greater than the first preset value, it indicates that the pot is dry-burned, otherwise, the pot is not dry-burned or continues to be detected, which is detailed in the embodiment shown in fig. 5.
S203, determining the dry burning of the cookware heated by the electromagnetic appliance.
In this embodiment, if the current heating power is less than or equal to the cache heating power, and the difference between the current PPG and the cache PPG is greater than or equal to the first preset value, it indicates that the pot is dry-cooked.
S204, determining that the cookware heated by the electromagnetic appliance is not dried.
In this embodiment, one of the schemes for detecting whether the pot is burned dry according to the heating power and the PPG is provided, that is, the current heating power is compared with the cache heating power, if the current heating power is less than or equal to the cache heating power, the current PPG is compared with the cache PPG, and if a difference value obtained by subtracting the cache PPG from the current PPG is greater than or equal to a first preset value, the pot is determined to be burned dry. Thereby when the pan is dry to burn, through heating power and PPG, in time confirm the pan is dry to burn to, whether detect the pan through heating power and PPG dry to burn, can improve the accuracy of testing result.
Fig. 4 is a flowchart of a pot dry-cooking detection method according to another embodiment of the present invention, as shown in fig. 4, the method of the present embodiment may include:
s301, judging whether the current PPG is equal to the maximum PPG of the IGBT, if so, executing S302; if not, executing S304;
in this embodiment, because the IGBT has a limitation on the on-time, the PPG of the IGBT needs to be controlled by the control module in the electromagnetic oven, and therefore, the PPG in the electromagnetic oven cannot be increased indefinitely. And the pot is dry-boiled, because the heating power is reduced, in order to maintain the heating power unchanged, PPG needs to be added. Therefore, the current PPG obtained is at most equal to the maximum PPG of the IGBT. Therefore, whether the current PPG is equal to the maximum PPG of the IGBT or not is judged, if the current PPG is equal to the maximum PPG of the IGBT, the pot has the possibility of dry burning, and S302 needs to be executed to further detect whether the pot is dry burning or not; if the current PPG is less than the maximum PPG of the IGBT, the pot may be considered to be not dry-burned, or continue to be detected, as detailed in the embodiment shown in fig. 6.
S302, judging whether the current heating power is smaller than the cache heating power, if so, executing S303; if not, executing S304;
in this embodiment, when the pan did not dry boil, if the PPG of electromagnetism stove reaches maximum PPG, then when the pan dry-burns, heating power reduces, and PPG also can not increase. Therefore, when the current PPG is equal to the maximum PPG, whether the current heating power is smaller than the cache heating power or not is judged, and if the current heating power is smaller than the cache heating power, the cookware is dry-burned.
In some embodiments, in the process of heating the pot by the induction cooker, under the condition that the pot is not dry-burned, the current heating power of the induction cooker may be reduced by a small margin, so that the current heating power is smaller than the cache heating power. Therefore, an implementation manner of S302 may be to determine whether a difference between the current heating power and the cached heating power is greater than a second preset value, if so, determine that the pot is dry-cooking, otherwise, determine that the pot is not dry-cooking. For example, when the difference value of the cache heating power minus the current heating power is greater than 100w, it indicates that the heating power of the induction cooker is still decreasing when the PPG reaches the maximum PPG, and thus it is determined that the pot is dry-cooked. Wherein, for different cooking functions, the second preset value may be different due to different bases of heating functions, for example, when the induction cooker performs a milk heating function, the second preset value may be 30w, and when the induction cooker performs a stir-frying function, the second preset value may be 100 w.
S303, determining the dry burning of the cookware heated by the electromagnetic appliance.
In this embodiment, when the current PPG is equal to the maximum PPG and the current heating power is less than the cache heating power, the cookware is determined to be dry-cooked.
S304, determining that the cookware heated by the electromagnetic appliance is not dried.
In this embodiment, one of the schemes for detecting whether the pot is burned dry according to the heating power and the PPG is provided, that is, the current PPG is first compared with the maximum PPG, if the current PPG is equal to the maximum PPG, the current heating power is compared with the cache heating power, and if the current heating power is smaller than the cache heating power, the pot is determined to be burned dry. Thereby when the pan is dry to burn, through heating power and PPG, in time confirm the pan is dry to burn to, whether detect the pan through heating power and PPG dry to burn, can improve the accuracy of testing result.
Fig. 5 is a flowchart of a pot dry-cooking detection method according to another embodiment of the present invention, as shown in fig. 5, the method of the present embodiment may include:
s401, judging whether the current heating power is smaller than or equal to the cache heating power, if so, executing S402; if not, executing S406;
in this embodiment, S301 may be referred to for a specific implementation manner of S401, and is not described herein again.
S402, judging whether the difference value of the current PPG minus the cache PPG is larger than or equal to a first preset value, if so, executing S405; if not, executing S403;
in this embodiment, when the pot is dry-boiled, the heating power is reduced, and the PPG is increased, so when the difference value obtained by subtracting the cache PPG from the current PPG is greater than the first preset value, it is determined that the pot is dry-boiled. However, since the PPG cannot be increased infinitely, the PPG does not increase when the pot is dry-boiled, if the PPG is increased to the maximum PPG, or if the PPG is already at the maximum PPG when the pot is dry-boiled, even if the heating power continues to decrease. It may result in the difference of the current PPG minus the buffered PPG being less than or equal to the first preset value. Therefore, if the difference between the current PPG and the cached PPG is less than or equal to the first preset value, it is necessary to determine whether the current PPG reaches the maximum PPG.
S403, judging whether the current PPG is equal to the maximum PPG of the IGBT, if so, executing S404 or S405; if not, executing S406;
in this embodiment, if the current PPG is equal to the maximum PPG, the pot dry-cooking can be directly determined. Or executing S404, and further judging whether the difference value between the cache heating power and the current heating power is greater than a second preset value, so as to further improve the detection accuracy. And if the current PPG is smaller than the maximum PPG, determining that the pot is not dried.
S404, judging whether the difference value of the current heating power minus the cache heating power is larger than a second preset value or not, if so, executing S405; if not, executing S406;
in this embodiment, when the difference between the cached heating power and the current heating power is greater than the second preset value, it is determined that the pot is dry-cooked, otherwise, it is determined that the pot is not dry-cooked.
S405, determining dry burning of the cookware heated by the electromagnetic appliance.
S406, determining that the cookware heated by the electromagnetic appliance is not dried.

Not only can detect the pan in time and burn futilely, further improve the accuracy that detects.
Fig. 6 is a flowchart of a pot dry-cooking detection method according to another embodiment of the present invention, as shown in fig. 6, the method of the present embodiment may include:
s501, judging whether the current PPG is equal to the maximum PPG of the IGBT, if so, executing S502; if not, executing S503;
in this embodiment, the current PPG is first compared with the maximum PPG, and if the current PPG is equal to the maximum PPG, the pot dry-cooking can be determined if the heating power is reduced. Thus, the current heating power is compared with the cache heating power.
If the current PPG is less than the maximum PPG, there may be a pot dry burn, but the PPG has not increased to the maximum PPG. Therefore, whether the difference value of the current PPG minus the cache PPG is larger than a first preset value or not is judged, and if the difference value of the current PPG minus the cache PPG is larger than the first preset value, the current heating power is compared with the cache heating power; and if the difference value of the current PPG minus the cached PPG is less than or equal to a first preset value, determining that the pot is dry-boiled.
S502, judging whether the current heating power is smaller than the cache heating power, if so, executing S504; if not, executing S505;
in this embodiment, if the current PPG is equal to the maximum PPG and the current heating power is less than or equal to the cache heating power, or the current PPG is less than the maximum PPG and a difference between the current PPG and the cache PPG is greater than a first preset value and the current heating power is less than or equal to the cache heating power, it is determined that the pot is dry-boiled. If the current PPG is equal to the maximum PPG, the current heating power is larger than the cache heating power, or the current PPG is smaller than the maximum PPG, the difference value of the current PPG minus the cache PPG is larger than a first preset value, and when the current heating power is larger than the cache heating power, the pan is determined not to be dry-burned.
S503, judging whether the difference value of the current PPG minus the cache PPG is larger than or equal to a first preset value, if so, executing S502; if not, executing S505;
in the embodiment, on the basis that the current PPG is smaller than the maximum PPG, if the difference value of the current PPG minus the cache PPG is smaller than or equal to a first preset value, the pan is determined not to be baked; if the difference value of the current PPG minus the cache PPG is larger than the first preset value, the possibility of dry burning exists in the pot, and therefore whether the heating power is reduced needs to be judged. And, when the pan is dry-burned, the heating power should be reduced, but because of the constant power control program in the electromagnetic oven, the heating power can be maintained unchanged by increasing the PPG, therefore, even if the heating power is not reduced, the difference value of the current PPG minus the cache PPG is greater than the first preset value, and when the current PPG is less than the maximum PPG, there is also a possibility of dry-burning of the pan. Therefore, when the difference value of the current PPG minus the cached PPG is greater than the first preset value and whether the heating power is reduced is determined, it needs to be determined whether the heating power is equal to the cached power. In this case, if the heating power is equal to the buffer power,
the dry burning of the pot can be determined.
S504, determining the dry burning of the cookware heated by the electromagnetic appliance.
And S505, determining that the cookware heated by the electromagnetic appliance is not dried.

Not only can in time detect the pan dry combustion method, can also further improve the accuracy that detects.
