Description

HALF FLEX TYPE INDUCTION HEATING DEVICE HAVING IMPROVED USER EXPERIENCE AND USER INTERFACE with improved user experience and user interface

The present invention relates to a Half Flex Type induction heating device with improved user experience and user interface.

BACKGROUND ART Various types of cooking utensils are used to heat food at home or in a restaurant. Conventionally, a gas range using gas as a fuel has been widely used, but recently devices for heating a heating target, such as a cooking vessel, such as a pot, have been made using electricity instead of gas.

A method of heating an object to be heated using electricity is largely divided into a resistance heating method and an induction heating method. The electric resistance method is a method of heating a heating target by transferring heat generated when a current flows through a metal resistance wire or a non-metallic heating element such as silicon carbide to the heating target (eg, a cooking vessel) through radiation or conduction. In the induction heating method, when high-frequency power of a predetermined size is applied to the coil, an eddy current is generated in the heating target made of a metal component using a magnetic field generated around the coil so that the heating target itself is heated. to be.

Among them, the induction heating apparatus to which the induction heating method is applied generally includes a working coil in each corresponding region to heat each of a plurality of heating objects (eg, a cooking vessel).

However, recently, an induction heating apparatus for simultaneously heating a single object with a plurality of working coils has been widely used. For example, in the case of a half flex type induction heating apparatus, a plurality of working coils may be respectively disposed in a plurality of regions spaced apart from each other. In this case, the induction heating device may induction heating the heating target by operating only some of the working coils according to the size of the heating target in a specific region in which a plurality of working coils exist.

For reference, the half-flex type induction heating device may be provided with an input interface. Such an input interface is a module for inputting a desired heating intensity or driving time by a user, and may be variously implemented as a physical button or a touch panel. In addition, the input interface may also be provided with a display panel on which the driving state of the induction heating device is displayed (ie, a touch screen type panel).

Here, when a hot container or a cutting board to which an external force is applied is positioned on the input interface during use of the induction heating device, there is a problem that the input interface is in danger of being damaged due to the hot container or the cutting board.

Accordingly, in the conventional induction heating apparatus, when the touch area of the input interface exceeds the reference area or more, a pop-up message (or image) not to cover the screen is displayed on the input interface.

However, this method of displaying a pop-up message based on the touch area has a problem in that, when a hot container having a reference area or less is disposed on the input interface, the pop-up message is not displayed and there is a risk that the input interface may be damaged due to heat. .

In addition, a pop-up message is not displayed even when an external force is applied because only a portion of the cutting board (ie, an area less than the reference area) is placed on the input interface and the input interface is vibrated due to vibration (ie, impact). There was also the risk of damage.

It is an object of the present invention to provide a half-flex type induction heating device that provides a protection notification function for an input interface by sensing heat or external force.

Another object of the present invention is to provide a half-flex type induction heating device with improved user experience (UX) and user interface (UI).

Specifically, the cover plate 119 may include a top plate 115 for placing an object to be heated, such as a cooking container, and the heat generated from the working coil (eg, WC) passes through the top plate 115 . It can be transferred to the object to be heated.

Here, the upper plate 115 may be made of, for example, a glass material, and the upper plate 115 has an input interface 300 that receives an input from a user and transmits the corresponding input to the first control module 310 . can be installed.

The input interface 300 is installed to be flatly embedded in the top surface of the cover plate 119, that is, the top plate 115 (that is, the top surface of the input interface 300 is disposed on the same plane as the top plate 115), You can display specific images. Also, the input interface 300 may receive a touch input from a user and provide the received touch input to the first control module 310 .

In addition, the input interface 300 may also be provided with a display panel on which the driving state of the half-flex type induction heating device is displayed (ie, a touch screen type panel).

For reference, the input interface 300 may transmit an input provided from a user to the first control module 310 , and the first control module 310 may transmit the input to the aforementioned second control module 320 . However, specific details thereof will be described later.

The sensor 330 may detect at least one of temperature and vibration of the input interface 300 .

Specifically, the sensor 330 detects at least one of temperature and vibration of the input interface 300 , and transmits information about at least one of the detected temperature and vibration of the input interface 300 to the first control module 310 . can provide

For reference, the sensor 330 may include a temperature sensor for detecting the temperature of the input interface 300 and a vibration sensor for detecting vibration (ie, impact) of the input interface 300 , but in some embodiments of the present invention In , for convenience of description, the temperature sensor and the vibration sensor will not be separately described, but will be described as one integrated sensor.

The first control module 310 receives information on at least one of the temperature and vibration of the input interface 300 from the sensor 330 , and receives information about at least one of the temperature and vibration of the input interface 300 . Based on this, it is possible to control whether the protection guide image of the input interface 300 is displayed.

Specifically, the first control module 310 may control driving of the input interface 300 . That is, the input interface 300 may display (ie, display) a specific image according to the control command of the first control module 310 .

In addition, the first control module 310 receives a user's touch input from the input interface 300 and transfers the received touch input to the second control module 320 or the input interface 300 based on the received touch input. You can control or select a specific image displayed on the .

In addition, the first control module 310 may receive information about the position of the heating target from the second control module 320 , and may receive information about the location of the heating target in the input interface 300 based on the received information on the position of the heating target. You can also control or select specific images to be displayed.

On the other hand, the second control module 320 may control the driving of the plurality of working coils WC, and detect which working coil among the plurality of working coils WC is positioned above the heating target.

Specifically, as described above, the second control module 320 may control the driving of the plurality of working coils WC by controlling the inverter unit and components related to driving thereof. In addition, the second control module 320 may provide information about the sensed position of the heating target to the first control module 310 , and may receive a user's touch input from the first control module 310 . .

Of course, the second control module 320 may control the driving of the plurality of working coils WC based on the user's touch input provided from the first control module 310 .

The plurality of working coils WC may be provided inside the case 125 , and driving may be controlled by the second control module 320 . In this case, the plurality of working coils WC may be disposed as shown in FIG. 2 or FIG. 3 .

Specifically, as shown in FIG. 2 , the half-flex type induction heating device 1 according to an embodiment of the present invention includes first and second working coils WC11, which are disposed on the half-free area HFZ. WC12), third and fourth working coils WC21 and WC22 disposed on the dual burner area DZ, and a fifth working coil WC5 disposed on the designated burner area SZ.

In this case, the half-free area HFZ, the dual burner area DZ, and the designated burner area SZ may be disposed to be spaced apart from each other.

On the other hand, as shown in FIG. 3 , the half-flex type induction heating device 2 according to another embodiment of the present invention has the first and second working coils WC11 disposed on the first half-free area HFZ1. , WC12), third and fourth working coils WC21 and WC22 disposed on the dual burner region DZ, and fifth and sixth working coils WC31 disposed on the second half-free region HFZ2; WC32).

In addition, the ferrite core may be fixed to the mica sheet through a sealant, and may serve to spread an alternating magnetic field generated from the working coil WC.

The mica sheet may be fixed to the working coil WC and the ferrite core through a sealant, and heat generated by the working coil WC may be prevented from being directly transferred to the ferrite core.

On the other hand, the half-flex type induction heating apparatus 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 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. Since the electronic device to which such wireless power transmission is applied does not require a wired cord or a charger, portability is improved, and its size and weight are reduced compared to the prior art.

Such wireless power transmission technology is largely classified into an electromagnetic induction method using a coil, a resonance method using resonance, and a radio wave radiation method in which electrical energy is converted into microwaves and transmitted. 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 half-flex type induction heating device is substantially the same 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 half-flex type induction heating devices 1 and 2 according to some embodiments 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 such, the half-flex-type induction heating apparatus (1, 2) according to some embodiments of the present invention has the above-described configuration and characteristics, hereinafter, in the control method of the half-flex-type induction heating apparatus (1, 2) to explain about it.

5 and 6 are schematic diagrams for explaining a method of displaying an automatic sensing mode in a half-flex type induction heating apparatus according to some embodiments of the present invention.

Here, FIG. 5 is a view for explaining the appearance of the interface 300 corresponding to the half-flex type induction heating device 1 according to an embodiment of the present invention of FIG. 2, and FIG. 6 is the present invention of FIG. It is a view for explaining the appearance of the interface 300 for the half-flex type induction heating device (2) according to another embodiment.

Specifically, when the heating target is placed on the upper plate 115 of the cover plate 119, the second control module 320 detects which working coil the corresponding heating target is located on among the plurality of working coils WC. can

Here, the second control module 320 may detect the degree of attenuation of the resonance current flowing through each working coil, and detect which working coil the heating target is located on based on the detection result.

To explain further, if the heating object is positioned on the working coil (eg, WC), the overall resistance may increase due to the resistance of the heating object, which causes the corresponding working coil (eg, WC) to The degree of attenuation of the flowing resonance current may be increased.

The second control module 320 detects the resonance current flowing through the working coil (eg, WC) in this way, and determines whether there is an object to be heated on the working coil (eg, WC) based on the detection value. is to detect

Of course, the second control module 320 may detect the heating target through other methods, but in the embodiment of the present invention, detecting the heating target by the above-described method will be described as an example.

When the position of the heating target is detected through this method, the second control module 320 may provide information about the sensed position of the heating target to the first control module 310 .

In addition, the first control module 310 provides an input interface ( 300) can be controlled.

For reference, the input interface 300 includes first to third area images (eg, HFZ, DZ, and SZ in FIG. 5 ) corresponding to the arrangement of the plurality of working coils WC, and an image of a crater for a heating target ( For example, FI11, F12, F21, F22, F3), a settings image (SI) showing settings icons (eg, pause icon, button lock icon, settings list icon, timer icon), and a secondary icon ( For example, an auxiliary image CI in which a heating target automatic detection state icon, a Wi-Fi connection state icon, and a current time display icon) is displayed may be displayed.

Hereinafter, for convenience of explanation, the first to third region images HFZ, DZ, and SZ shown in FIG. 5 will be described as an example.

The first to third area images HFZ, DZ, and SZ are displayed blurry than the corresponding crater images for the heating target (eg, FI11, FI12, FI21, FI22, FI3). In this case, the first to third region images HFZ, DZ, and SZ are arranged to correspond to positions of the plurality of working coils WC of FIG. 2 .

Specifically, the first area image HFZ represents a half-free burner area, and the first area image HFZ includes two burner areas arranged vertically. Each burner area corresponds to the first and second working coils WC1 and WC2 of FIG. 2 .

For example, when a heating object is simultaneously detected by the first and second working coils WC1 and WC2, the crater images FI11 and FI12 for the heating object are individually activated on the two burner areas at the same time (FIG. 5). <C>). In this case, the user can control the two cooking areas by linking them at the same time by selecting the half-flex button image FB. This will be described later with reference to FIG. 8 .

In addition, when a heating object is detected in any one of the first or second working coils WC1 and WC2, only the crater image FI1 for the heating object corresponding to the burner area in which the heating object is sensed may be activated (Fig. <B> of 5).

The second area image DZ represents a dual burner area, and includes two burner areas having the same center and different diameters. Each burner area corresponds to the third and fourth working coils WC3 and WC4 of FIG. 2 .

For example, if the diameter of the heating target is relatively large and the third and fourth working coils WC3 and WC4 detect the heating target at the same time, the crater image FI22 for the heating target including two burner areas is displayed. is activated (<C> in FIG. 5). On the other hand, when the heating target is detected only by the third working coil WC3 because the diameter of the heating target is relatively small, the crater image FI21 for the heating target including only the burner area having a small diameter is activated (Fig. B>).

The third area image SZ represents a single burner area, and consists of only one circular burner area. When the heating target is detected by the fifth working coil WC5, the crater image FI3 for the heating target is activated (<B> and <C> of FIG. 5 ).

A power image PI for activating the operation of the corresponding working coil WC may be displayed at the center of each of the heating element images (eg, FI11, FI12, FI21, FI22, FI3).

In addition, the setting image SI and the auxiliary image CI may be displayed at the bottom of the input interface 300 .

That is, when the input interface 300 is turned on, the first to third region images HFZ, DZ, and SZ are displayed on the upper part of the input interface 300 , and the setting image SI and the auxiliary image CI are displayed on the lower part of the input interface 300 . ) is displayed.

Subsequently, when the object to be heated is disposed on the upper plate part 115 and its position is sensed by the second control module 320 , the heating object image FI and the power image PI are additionally provided to the input interface 300 . can be displayed.

At this time, the first control module 310 is configured to display the image FI of the heating target for the heating target on the input interface 300 based on the information on the position of the heating target provided from the second control module 320 . (300) can be controlled.

6, the interface 300 for the half-flex type induction heating device 2 according to another embodiment of the present invention is the first to third area images corresponding to the arrangement of the plurality of working coils (WC) ( For example, HFZ1, DZ, HFZ2), an image of a heating target (eg FI11, F12, F21, F22, F31, F32), a setting image (SI), and an auxiliary image (CI) are displayed. can be

Here, the first and third area images HFZ1 and HFZ2 may be displayed in substantially the same manner as the first area image HFZ of FIG. 5 . The remaining regions (that is, the second region image DZ, the heating target image FI, the setting image SI, and the auxiliary image CI) may be displayed in the same manner as described with reference to FIG. 5 . .

Additionally, the first control module 310 may control the input interface 300 so that the crater image FI for the heating target is displayed on the input interface 300 in different ways depending on whether the automatic detection mode is activated.

Specifically, when the automatic detection mode is activated, the first control module 310 displays the first to third region images HFZ, DZ, and SZ, and does not display the heating target image FI. Subsequently, when the heating target is detected by the second control module 320, only the heating target image FI corresponding to the corresponding area is displayed (<A> -> <B> in FIGS. 5 and 6) .

Conversely, when the automatic detection mode is deactivated, the first control module 310 activates and displays all of the heating target images FI on the first to third region images HFZ, DZ, and SZ (FIG. 5). and <A> -> <C> in FIG. 6). Subsequently, when the object to be heated is detected by the second control module 320, the first control module 310 adjusts the size of the crater image FI for the object to be heated in the corresponding area in which the object to be heated is detected to input interface ( 300) (that is, the size of the heating target image FI is adjusted according to the detected heating target, and the heating target image FI is displayed even in the area where the heating target is not detected) (<C> -> <B> in FIGS. 5 and 6).

For reference, this is only an example, and the display method of the crater image FI for the heating target may be variously modified and implemented.

7 to 9 are schematic diagrams for explaining a method of displaying a crater image in a half-flex type induction heating apparatus according to some embodiments of the present invention.

First, referring to FIG. 7 , the input interface 300 includes first to third area images (HFZ1, DZ, HFZ2), a heating target image (FI1 to FI3) corresponding to each area, and a setting icon. The displayed setting image SI and the auxiliary image CI on which the auxiliary icon is displayed are displayed.

The images of the first to third regions (HFZ1, DZ, HFZ2) are displayed more blurry than the images of the heating target (FI1 to FI3), and appear at the same time as the half-flex type induction heating device is turned on.

The heating target images FI1 to FI3 are displayed at positions corresponding to the working coil WC to which the current heating target is applied.

For reference, the images displayed inside the heating target images FI1 to FI3 have a common meaning.

First, in the first heating target image FI21, the power image PI is displayed in the center, and when the user touches the power image PI, the working coil WC corresponding to the corresponding cooking zone starts operation. .

The second heating target image FI22 is displayed when the user touches the power image PI. In this case, the second heating target image FI22 includes a heating intensity image PL, a timer image T, and an end image TI.

Here, the heating intensity image PL represents the output level of the working coil WC, the timer image T represents an icon that can set the operating time of the working coil WC, and the end image TI represents the working coil WC. An icon that immediately stops the operation of the coil WC is displayed.

As will be described in detail below, the temperature of the crater does not drop immediately even if the operation of the working coil (WC) is stopped. It may be displayed in the crater image FI22.

At this time, the heating intensity image PL is disposed above the heating target image FI2, the timer image T is disposed below the heating target image FI2, and the end image TI is It may be disposed on the boundary line of the crater image FI2 for the heating body.

The third heating target image FI23 is displayed when the user selects the timer image T to set the operating time of the working coil WC. Here, the operation time represents the remaining time for the operation of the working coil WC.

Additionally, the setting image SI includes a temporary lowering icon SI1 , a button lock icon SI2 , a setting list icon SI3 , and a timer icon SI4 .

Here, the temporarily lowering icon SI1 temporarily lowers or restores the temperature of each cooking area to the state before the lowering. The button lock icon SI2 performs a clean lock operation to prevent other buttons from being input for a predetermined period of time. The setting list icon SI3 converts to a screen where operation options of the half-flex type induction heating device can be set. The timer icon SI4 switches to a screen for setting the operation time of the working coil WC.

The auxiliary image CI includes a heating target automatic detection mode icon CI1, a Wi-Fi connection status icon CI2, and a current time display icon CI3.

Here, the auto-sensing mode icon CI1 of the object to be heated is displayed when the auto-sensing mode is activated in the half-flex type induction heating device. The Wi-Fi connection status icon (CI2) is displayed when the half-flex type induction heating device is in a Wi-Fi connection enabled state. The current time display icon CI3 displays the current time on the screen.

The image <D5> shows a case in which the object to be heated is detected on the first and second working coils WC1 and WC2 in a state in which the first sub-region A1 and the second sub-region A2 are linked. One crater image FIT for a heating target is displayed on the first sub-area A1 and the second sub-area A2 , and in this case, the first and second working coils WC1 and WC2 may be simultaneously controlled.

Referring to FIG. 9 , the second region image DZ includes a third sub region A3 corresponding to the third working coil WC3 and a fourth sub region A4 corresponding to the fourth working coil WC4 . do. The third sub-area A3 and the fourth sub-area A4 are disposed to have the same center.

Specifically, the <E1> image appears when the object to be heated is not detected on the third and fourth working coils WC3 and WC4. In this case, blurred images representing the third sub-region A3 and the fourth sub-region A4 are displayed on the second region image DZ.

Specifically, referring to FIGS. 10 and 11 , the input interface 300 transmits an input for touching the power image PI to the first control module 310 when an input for touching the power image PI is received from the user. can provide In addition, the first control module 310 provides at least one of a heating intensity image PL and a timer image T to the input interface 300 based on an input for touching the power image PI provided from the input interface 300 . may be controlled to display the input interface 300 .

That is, when the user touches the power image PI, the heating intensity image PL and the timer image T may be displayed on the input interface 300 instead of the power image PI. Also, a heating intensity selection image PL PICKER may be displayed on the input interface 300 to select the heating intensity.

In this case, the user may provide an input related to a specific heating intensity (for example, an input for touching a heating intensity of 3.5) to the input interface 300 through a drag operation, and the specific heating intensity selected by the user is the heating It may be displayed on the intensity image PL.

For reference, even when the user provides only an input related to a specific heating intensity to the input interface 300 without an input related to the timer, when a preset time (for example, 3 seconds) has elapsed, the heating operation will be automatically started. can

In addition, as shown in FIG. 12 , when the user touches the timer image T while the heating intensity image PL and the timer image T are displayed on the input interface 300 , the timer is selected so that the timer can be selected. An image (TIMER SETTING) may be displayed on the input interface 300 .

In this case, the user may make a touch input regarding specific hour and minute values through a drag operation, and then may set a timer by touching an 'OK' icon.

Of course, the timer selected by the user can be counted after being displayed with the changed timer image T', and when the predetermined time is over, the power image PI can be displayed again in the center of the heating target image FI. have.

In addition, when residual heat remains in the upper plate part 115 , the residual heat image RHI may also be displayed inside the heating target image FI.

Meanwhile, the input interface 300 may provide an input related to a specific heating intensity to the first control module 310 when receiving an input related to a specific heating intensity from a user. In addition, the first control module 310 provides an input related to a specific heating intensity to the second control module 320, and as shown in FIG. 13, based on the input related to the specific heating intensity, to the input interface 300 The input interface 300 may be controlled so that the heating images HI1 and HI2 are displayed. In addition, the second control module 320 may drive a working coil disposed at a position where a heating target is sensed among a plurality of working coils (eg, WC) based on an input related to a specific heating intensity.

That is, referring to FIG. 13 , the heating intensity image (PL) and the changed timer image (T') as well as the heating image (HI1, HI2) are displayed as a background image in the center of the heating target image (FIT, FI2) for the object to be heated. can

Specifically, the heating images HI1 and HI2 may be displayed in a specific area of the input interface 300 in which the heating target images FIT and FI2 are displayed, and may be repeatedly displayed in the form of a dynamic image. Accordingly, the heating images HI1 and HI2 may be repeatedly reproduced on the input interface 300 in the form of a motion that embodies the color and shape of the flame while the working coil is being driven (ie, during heating operation).

Through this, the user can easily visually recognize that the heating operation of the current heating target is in progress.

For reference, the heating images HI1 and HI2 of FIG. 13 may be expressed as animations having various colors and shapes, and may be transformed into various shapes and implemented.

Next, referring to FIG. 14 , a method of displaying a protection guidance image in a half-flex type induction heating device is illustrated.

For reference, FIG. 14 is a view for explaining a schematic appearance of an input interface when a protection guide image is displayed.

Specifically, as described above, the input interface 300 may receive a touch input from a user and may provide the received touch input to the first control module 310 . Also, the first control module 310 may receive information about at least one of temperature and vibration of the input interface 300 from the sensor 330 .

In addition, the first control module 310 may control whether to display the protection guide image of the input interface 300 based on information about at least one of temperature and vibration of the input interface 300 provided from the sensor 330 . .

That is, the first control module 310 analyzes information about at least one of temperature and vibration of the input interface 300 provided from the sensor 330 , compares the analysis result with a preset reference level, and compares the comparison result with a preset reference level. Based on this, it is possible to control whether the protection guide image of the input interface 300 is displayed.

Specifically, when the analysis result is higher than the preset reference level, the first control module 310 may control the input interface 300 to display the protection guide image PGI on the input interface 300 .

On the other hand, in a state in which the protection guide image PGI is displayed on the input interface 300 , the first control module 310 relates to at least one of the temperature and vibration of the input interface 300 newly provided from the sensor 330 . If the result of analyzing the information is lower than or equal to the preset reference level, the first control module 310 may control the input interface 300 so that the protection guide image PGI displayed on the input interface 300 disappears. .

For reference, the analysis result may be a result of comprehensive analysis of each numerical value of the temperature and vibration of the input interface 300 , and a preset reference level may also be a single value.

Of course, when the analysis result is divided into the analysis result for the temperature of the input interface 300 and the analysis result for the vibration of the input interface 300 , the preset reference level is also the reference level for the temperature and the reference level for the vibration can be divided into In addition, the comparison result with the reference level for each of the temperature and vibration may be reflected in whether the protection guidance image (PGI) is displayed.

However, in some embodiments of the present invention, for convenience of explanation, it will be described as an example that the analysis result is a result of comprehensive analysis of the temperature and vibration values of the input interface 300 .

Based on the above-described method, as shown in FIG. 14 , when the analysis result of the temperature and vibration of the input interface 300 is higher than the preset reference level, the protection guide image PGI is the existing crater for the heating target. It may be displayed on the input interface 300 so as to overlap on the images FIt and FI2.

On the other hand, when the analysis result of the temperature and vibration of the input interface 300 is lower than or equal to the preset reference level again, the protection guide image PGI displayed on the input interface 300 may disappear.

For reference, a warning phrase such as 'Please remove the cooking utensils from the screen' may be displayed in the protection guide image PGI, but the present invention is not limited thereto.

Also, although not shown in the drawings, the half-flex type induction heating devices 1 and 2 may be equipped with a speaker (not shown; that is, a sound module). In this case, the first control module 310 may control whether to output the protection guidance voice of the speaker based on the comparison result.

That is, when the analysis result is higher than the preset reference level, the first control module 310 repeats the protection guidance voice (eg, 'Please remove the cooking utensils on the screen') from the speaker for a preset number of times or for a period of time. You can control the speaker to output.

Of course, the first control module 310 may simultaneously control the input interface 300 and the speaker so that the protection guide image PGI is displayed on the input interface 300 and the protection guide voice is output from the speaker.

However, for convenience of description, in some embodiments of the present invention, only a case in which the protection guide image PGI is displayed on the input interface 300 will be described as an example.

In summary, when heat or vibration (ie, impact) above a predetermined reference level is applied to the input interface 300, the protection guide image (PGI) is displayed in a pop-up form on the input interface 300 to inform the user, Damage to the input interface 300 due to heat or vibration may be prevented in advance.

That is, the half-flex type induction heating device 1, 2 according to some embodiments of the present invention has a protection function for the input interface 300, so that the input interface 300 is caused by heat or vibration (ie, shock). It can reduce the risk of damage. Furthermore, the product lifespan of the input interface 300 may be improved by reducing the risk of damage to the input interface 300 .

In addition, the half-flex type induction heating devices 1 and 2 according to some embodiments of the present invention can improve the user's convenience in various situations by improving the user experience and user interface.
