Description

Electric range in which operation is controlled based on physical state of object to be heated and method for controlling the same

The present invention relates to an electric range in which operation is controlled based on a physical state of a heating target and a method for controlling the same.

BACKGROUND ART Various types of cooking utensils are used to heat food at home or in a restaurant. The above-described cooking appliance includes a gas range using gas and an electric range using electricity.

Electric ranges are largely divided into resistance heating methods and induction heating methods. In the electrical resistance method, a current is applied to a non-metal heating element such as a metal resistance wire or silicon carbide to generate heat, and the generated heat is radiated or conducted to heat an object to be heated (eg, a cooking vessel such as a pot or a frying pan). to be. In the induction heating method, a high-frequency power is applied to a coil to generate a magnetic field around the coil, and an eddy current generated in the generated magnetic field is used to heat a heating target made of a metal component.

Meanwhile, the gas range controls heat power through manipulation of a knob, and the electric range controls heat power through touch manipulation of a specific image displayed on an input interface. However, compared to the handle operation, the touch operation has a disadvantage in that it is not possible to quickly adjust the heat power.

As an example, when the contents in the cooking container boil over or become severely heated, a user using a gas cooker can quickly lower the heat by rotating the handle quickly, but a user using an electric range may repeatedly perform a touch operation to adjust the heat. It must be carried out with this, so the firepower cannot be lowered quickly.

In addition, the electric range can simultaneously heat a plurality of heating targets through a plurality of cooking spheres. In this case, only one heating sphere is controlled at one time. Accordingly, the user must control the heating power of the crater after selecting an image corresponding to the crater to be controlled on the input interface. However, the manipulation as described above causes inconvenience to the user.

On the other hand, the induction heating apparatus 1 according to an embodiment of the present invention may also have a wireless power transmission function based on the above-described configuration and features.

That is, recently, a technology for wirelessly supplying power has been developed and is being applied to many electronic devices. For electronic devices with wireless power transfer technology, the battery is charged simply by placing it on the charging pad without connecting a separate charging connector. An electronic device to which wireless power transmission is applied does not require a wired cord or a charger, so portability is improved and the size and weight are reduced compared to the prior art.

Wireless power transmission technology largely includes an electromagnetic induction method using a coil, a resonance method using resonance, and a radio wave radiation method that converts electrical energy into microwaves and transmits them. Among them, the electromagnetic induction method is a technology for transmitting power using electromagnetic induction between a primary coil (eg, a working coil) provided in a device for transmitting wireless power and a secondary coil provided in a device for receiving wireless power to be.

Of course, the induction heating method of the induction heating device 1 has substantially the same principle as the wireless power transmission technology by electromagnetic induction in that the heating target is heated by electromagnetic induction.

Therefore, even in the case of the induction heating apparatus 1 according to an embodiment of the present invention, not only the induction heating function but also the wireless power transmission function may be mounted. Furthermore, the induction heating mode or the wireless power transmission mode may be controlled by the first control module 310, and it is possible to selectively use the induction heating function or the wireless power transmission function as needed.

As described above, the induction heating apparatus 1 according to an embodiment of the present invention has the above-described configuration and characteristics. Hereinafter, the operation of the induction heating apparatus 1 is controlled based on the physical state of the object to be heated. The control method will be described.

4 is a diagram illustrating a flowchart of a method for controlling the operation of the induction heating device 1 based on the physical state of the heating target according to an embodiment of the present invention.

At this time, for convenience of description, it is assumed that two heating objects, that is, heating object A and heating object B, are disposed on the upper surface of the cover plate 119 .

In addition, the present invention will be described by collectively referring to the first control module 210 and the second control module 220 as one control unit.

In addition, it is assumed that the crater image A corresponding to the crater for heating the heating target A and the crater image B corresponding to the crater for heating the heating target B are both deactivated and displayed in the input interface 300 .

Hereinafter, the process performed for each step will be described in detail.

In step S410, the sensor unit detects the physical state of the heating target A and the heating target B.

According to an embodiment of the present invention, the sensor unit may include at least one of two or more weight sensors 340 and two or more vibration sensors 350 . In addition, the physical state of the heating target may include at least one of a weight of the heating target and vibration generated in the heating target.

More specifically, the content is contained in the heating target. In this case, the weight of the heating target is a concept including all the weight of the contents (eg, water, oil, etc.) contained in the heating target (eg, a cooking container).

In addition, vibration in the heating target may occur due to boiling of the contents in the heating target (natural vibration), or may occur when the user touches the heating target with a specific vibration pattern through a hand or a cooking tool ( artificial vibration).

In step S420 , the control unit determines whether the physical states of the heating target A and the heating target B are changed.

That is, in step S420 , the controller may determine whether the weights of the heating target A and the heating target B are changed and whether the vibrations in the heating target A and the heating target B are changed. At this time, as mentioned above, the vibration includes natural vibration and artificial vibration.

Meanwhile, the controller may determine whether the weight of the heating target is changed based on a preset threshold weight value. That is, when the weight of the heating target increases or decreases by more than a critical weight value, it may be determined that the weight of the heating target has changed. This is to prevent malfunction of the induction heating device 1 due to a small change in weight.

And, when the content contained in the heating target is increased or decreased, the weight of the heating target may be changed. For example, when the user puts water, vegetables, etc. in the heating target, the weight of the heating target may be increased, and when the user pours water into the heating target, the weight of the heating target may be reduced.

In addition, the control unit may determine whether the vibration of the heating target is changed based on a preset threshold vibration value. That is, when the vibration in the heating target increases or decreases by more than the critical vibration value, it may be determined that the vibration in the heating target is changed. This is to prevent malfunction of the induction heating device 1 due to the occurrence of small vibrations.

In addition, when the contents contained in the heating target boil, or when the user touches the heating target by hand or through a cooking tool, vibrations greater than or equal to the threshold vibration value may occur.

If the physical states of the heating target A and the heating target B are not changed, in step S430 , the input interface 300 deactivates both the cooking zone image A and the heating target image B and displays them.

Hereinafter, the process performed in step S430 will be described with reference to FIG. 5 as follows.

When the crater image A 510 and the crater image B 520 are displayed in an inactive manner on the input interface 300, the user wants to manually control the crater image A 510 and the crater image B 520, For example, the crater image B 520 is selected and touched 530 . The input interface 300 activates the crater image B 520 and displays a thermal power adjustment image 540 for controlling the thermal power of the crater corresponding to the activated crater image B 520 . The user manipulates the thermal power adjustment image 540 displayed on the input interface 300, and the controller controls the working coil WC to control the thermal power of the crater corresponding to the activated crater image B 520 based on the manipulation. do.

Conversely, when the physical state of one of the heating target objects A and the heating target B, that is, the first heating target body is changed, in step S440, the controller controls the second of the plurality of working coils WC. 1 It is possible to control at least one of the plurality of working coils WC and the input interface 300 so that the user preferentially manipulates the working coil WC for heating the object to be heated.

Hereinafter, the process performed in step S440 will be described with reference to FIGS. 6 and 7 . Meanwhile, for convenience of description, the first heating target whose weight or vibration is changed will be referred to as heating target B. FIG.

In the input interface 300, the crater image A 510 and the crater image B 520 are displayed in an inactive manner, and the weight of the heating target B is changed to a critical weight or more, or vibration of the heating target B is greater than or equal to the critical vibration value. can occur. In this case, the controller may activate the crater image B (that is, the first crater image corresponding to the crater for heating the first object to be heated) and display the image of the crater other than the crater image B, that is, the crater image A. The input interface 300 may be controlled to deactivate.

More specifically, when the weight of the heating target B is changed, the user is highly likely to perform a specific action on the heating target B with the changed weight, and the user is highly likely to change the thermal power of the heating target B with the changed weight. As an example, when the weight of the heating target B increases, the user is highly likely to increase the thermal power of the crater for heating the heating target B.

Accordingly, referring to FIG. 6 , when the weight of the heating target B is changed, the induction heating device 1 displays at least one image corresponding to the heating target B (ie, the crater image B 520 , the thermal power adjustment image). (540), etc.) may be given operation priority.

That is, without user intervention, the controller may control the input interface 300 to activate the crater image B 520 corresponding to the heating target B whose weight has been changed. Thereafter, the heat control image 540 linked to the cooking zone image B 520 may be displayed on the input interface 300 , and the user may correspond to the heating zone image B 520 through manipulation of the heating power control image 540 . You can control the firepower of the crater being used. Accordingly, it is possible to improve the operation convenience of the user using the induction heating device (1).

In addition, when natural vibration occurs in the heating target B, there is a high possibility that the contents in the heating target B boil over or the heating target B is heated excessively, and the user There is a high possibility of changing the firepower. As an example, when natural vibration occurs in the heating target B, the user is highly likely to reduce the thermal power of the heating target heating the heating target B in order to cool the contents in the heating target B.

Accordingly, referring to FIG. 6 , when natural vibration or artificial vibration occurs in the heating target B, the induction heating device 1 displays at least one image corresponding to the heating target B (ie, the crater image B 520 ). ), heat control image 540, etc.) may be given priority in operation.

That is, without user intervention, the controller may control the input interface 300 to activate the crater image B 520 corresponding to the heating target B in which vibration has occurred. Thereafter, the heat control image 540 linked to the cooking zone image B 520 may be displayed on the input interface 300 , and the user may correspond to the heating zone image B 520 through manipulation of the heating power control image 540 . You can control the firepower of the crater being used. Accordingly, it is possible to quickly reduce the thermal power of the crater, and it is possible to improve the operation convenience of the user using the induction heating device 1 .

On the other hand, in a situation in which the crater image B 520 is activated and the thermal power control image 540 linked to the crater image B 520 is displayed, the user's input event for the manipulation of the thermal power control image 540 is a preset time There may be situations where it is not performed within the interval. In this case, when the time period has elapsed, the controller may control to turn off the thermal power of the at least one working coil WC corresponding to the object B to be heated.

For example, the situation in which the user cannot operate the heat control image 540 because it is not located adjacent to the induction heating device 1 is the above-described situation. At this time, if the user does not input a touch event for the thermal power control image 540 within 5 seconds, the control unit may control to turn off the thermal power of at least one working coil WC corresponding to the heating target B. have. Accordingly, it is possible to prevent an emergency from occurring in the process of heating and cooking.

On the other hand, it may be generated that a predefined vibration pattern is sensed in the object B to be heated. As an example, the vibration pattern may include a pattern in which the user periodically touches the heating target B a plurality of times through a hand or an early tool.

In this case, the controller may control to adjust the thermal power of at least one working coil WC corresponding to the heating target B among the plurality of working coils WC based on the sensed vibration pattern.

According to an embodiment of the present invention, the controller may control to turn off the thermal power of the at least one working coil WC corresponding to the heating target B. This is as shown in FIG. 7 .

As an example, referring to FIG. 7 , when a vibration pattern repeatedly touching the heating target B three times is sensed, the control unit turns off the thermal power of at least one working coil WC corresponding to the heating target B, It is possible to control the turned-off crater image B 520 to be displayed on the input interface 300 .

In addition, according to another embodiment of the present invention, when a vibration pattern is sensed at the first point of the heating target B, the control unit increases the thermal power of at least one working coil WC for heating the heating target B. can be controlled In addition, when the vibration pattern is sensed at the second point of the heating target B, the controller may control to reduce the thermal power of the at least one working coil WC for heating the heating target B. In this case, the first point may be a point opposite to the second point.

As an example, when a vibration pattern repeatedly touching the right point of the heating target B three times is sensed, the control unit may increase the thermal power of at least one working coil WC corresponding to the heating target B, and When the vibration pattern repeatedly touching the left point of the body B three times is sensed, the thermal power of the at least one working coil WC corresponding to the heating target B may be reduced. Meanwhile, two or more vibration sensors may be disposed adjacent to the working coil WC to perform such an operation.

On the other hand, there may be a case in which a change in weight is detected in the heating target A and vibration occurs in the heating target B at the same point in time. In this case, the control unit may control so that the user can preferentially operate the blood-x body B in which the vibration has occurred.

That is, the control of the induction heating device 1 according to the change in weight is for the user's convenience of operation, and the control of the induction heating device 1 according to the generation of vibration is the process of heating and cooking as well as the user's operation convenience. This is to prevent emergencies from occurring. Therefore, when the weight change and the generation of vibration are sensed at the same time, the control unit may give priority to the operation of the heating target B in which the vibration has occurred.

In summary, in the present invention, the operation of the induction heating device 1 is controlled based on the physical state (weight, vibration) of the object to be heated. That is, when the physical state (weight, vibration) of a specific heating target is changed, the operation of the induction heating device 1 is controlled so that the operation of the heating target on which the change has been performed can be preferentially performed.

Accordingly, the operation of the induction heating device 1 can be automatically controlled based on the physical state of the object to be heated. In addition, even when an emergency situation occurs in the process of heating and cooking using the induction heating device 1 , the user can quickly solve the emergency situation without a separate manipulation action. In addition, it is possible to improve the operation convenience of the induction heating device (1).
