Description

Johnfree type induction heater with improved user experience and user interface

The present invention relates to a John Free type induction heating apparatus with improved user experience and user interface.

Various types of cooking utensils are used to heat food at home or in restaurants. Background Art Conventionally, gas ranges using gas as a fuel have been widely used, but recently, devices for heating cooking vessels such as pots, such as pots, using electricity without using gas have been widely used.

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

The induction heating apparatus to which the induction heating system is applied is generally provided with the walking coil in the corresponding area | region for heating each of several to-be-heated objects (for example, a cooking container).

Recently, however, an induction heating apparatus (ie, a zone free type induction heating apparatus) that simultaneously heats one object with a plurality of working coils has been widely used. In the case of the zone-free induction heating apparatus, the heated object can be inductively heated regardless of the size and position of the heated object in the region where the plurality of working coils are present.

For reference, the John Free type induction heating apparatus may be provided with an input interface. The input interface is a module for inputting a heating intensity or driving time desired by a user, and may be variously implemented as a physical button or a touch panel. In addition, the input interface may be provided with a display panel displaying a driving state of the induction heating apparatus.

Here, when the input interface is formed of a display panel (that is, a touch screen panel), there is a problem that the input interface is damaged due to a hot container or a cutting board.

Accordingly, in the conventional zone-free induction heating apparatus, when the touch area of the input interface exceeds the reference area or more, a pop-up message (or an image) is displayed on the input interface.

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

In addition, even if only a part of the cutting board (ie, an area below the reference area) is placed on the input interface, a pop-up message is not displayed even if the cutting is performed, so that the input interface may be damaged due to vibration (ie, impact). There is also a problem that there is.

First, referring to FIGS. 2 to 6, a method of displaying a crater image for a heated object is illustrated.

For reference, FIG. 2 is a view illustrating an actual appearance of the input interface 300 on which a crater image for a heating target is displayed, and FIG. 3 is a schematic diagram of the input interface 300 when one crater image for a heating target is displayed. 4 is a view for explaining a state, and FIG. 4 is a view for explaining a schematic view of the input interface 300 when a plurality of crater images for a heating object are displayed.

Specifically, when the heating object is placed on the upper plate 115 of the cover plate 119, the second control module 320 has the heating element on the top of any working coil of the plurality of working coils (for example, WC). You can detect the location.

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

In detail, when the heating element is placed on the working coil (eg, WC), the resistance of the heating element may increase the overall resistance, thereby causing the corresponding working coil (eg, WC) to be Attenuation of the flowing resonance current may be increased.

The second control module 320 detects the resonance current flowing in the working coil (for example, WC) in this way, and detects whether a heating target is present on the working coil (for example, WC) based on the detected value. It is.

Of course, the second control module 320 may detect the heated object through another method. However, in the embodiment of the present invention, the second heated control module 320 detects the heated object by the above-described method.

When the position of the object to be heated is sensed through the above method, the second control module 320 may provide the first control module 310 with information about the detected position of the object to be heated.

In addition, the first control module 310 displays the crater image FI for the heated object on the input interface 300 based on the information about the position of the heated object received from the second control module 320. ) Can be controlled.

For reference, as shown in FIG. 4, for example, the input interface 300 includes a crater image FI for a heating object, a setting icon (for example, a pause icon, a button lock icon, a setting list icon, A setup image (SI) with a timer icon) and a secondary image (CI) with a sub-icon (e.g., Auto-detected status icon, Wi-Fi connection status icon, current time display icon). have.

In addition, the crater image FI for the heating target is displayed on a specific area of the input interface 300 to correspond to the position of the heating target on the cover plate 119, and the size and rotation direction of the heating target may be reflected and displayed. have.

That is, the crater image for the heating object in a specific area of the input interface 300 corresponding to the actual position of the heating object on the upper plate 115 based on the scale of the input interface 300 relative to the upper plate 115 of the cover plate 119. (FI) may be displayed.

In addition, the power image PI may be displayed in the center of the crater image FI for the heating element.

Accordingly, as shown in FIG. 5, the set image SI is inputted to the input interface 300 before the heating element is disposed on the upper plate 115 in a state where the power of the zone-free induction heating apparatus 1 is turned on. And only the secondary image CI may be displayed.

However, when the heated object is disposed on the upper plate 115 and its position is detected by the second control module 320, the burner image FI and the power image PI for the heated object are further displayed on the input interface 300. Can be.

In addition, as shown in FIG. 6, assuming that the total number of the heated objects to be heated is six, when six to-be-heated objects are arranged on the upper plate part 115, six burner crater images FI1 to FI6. ) May be displayed on the input interface 300 along with the power image.

However, when the seventh to-be-heated body is disposed on the upper plate 115 to exceed the total number of heatable to-be-heated bodies, the seventh to-be-heated body crater image FI ′ may be blurred and the power image may not be displayed. have.

As a result, the seventh crater image FI ′ is not selectable.

2, 3, 7 and 9, a method of displaying a heating intensity image and a timer image is shown.

For reference, FIG. 7 is a view illustrating an actual appearance of an input interface on which a heating intensity image, a timer image, and a heating intensity selection image are displayed, and FIG. 8 illustrates a schematic view of the input interface when the heating intensity is displayed after being selected. 9 is a view for explaining a schematic view of the input interface when the timer is displayed after being set.

In detail, the input interface 300 may provide an input for touching the power image (PI in FIG. 4) to the first control module 310 when an input for touching the power image (PI in FIG. 4) is received from the user. Can be. In addition, the first control module 310 of the heating intensity image (PL) and the timer image (T) of the input interface 300 on the basis of the input to touch the power image (PI of FIG. 4) received from the input interface 300 The input interface 300 may be controlled to display at least one.

Furthermore, as shown in FIG. 8, 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. In addition, the 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 regarding the specific heating intensity (eg, an input of touching a heating intensity of 4.5) to the input interface 300 through a dragging operation, and the specific heating intensity selected by the user may be heated. It may be displayed on the intensity image PL.

For reference, even when the user provides only the input about the specific heating intensity to the input interface 300 without the input regarding the timer, when the preset time (for example, 3 seconds) elapses, the heating operation is automatically started. Can be.

In addition, as shown in FIG. 9, 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 to select a timer. An image TIMER SETTING may be displayed on the input interface 300.

In this case, the user may make a touch input regarding a specific hour and minute value through a drag operation, and then set a timer by touching an 'OK' icon. Of course, the timer selected by the user may be counted after being displayed as the changed timer image T ', and when the predetermined time is over, the power image PI may be displayed again in the center of the burner image FI for the heating object. have. In addition, when residual heat remains on the upper plate 115, the residual heat image RHI may also be displayed in the center of the crater image FI for the heating object.

Meanwhile, when the input interface 300 receives an input regarding a specific heating intensity from a user, the input interface 300 may provide an input regarding the specific heating intensity to the first control module 310. In addition, the first control module 310 provides an input regarding the specific heating intensity to the second control module 320, and as shown in FIG. 10, the first control module 310 heats the input interface 300 based on the input relating to the specific heating intensity. The input interface 300 may be controlled to display the image HI. In addition, the second control module 320 may drive the working coil disposed at a position where a heated object is detected among the plurality of working coils (for example, WC) based on an input regarding a specific heating intensity.

That is, referring to FIG. 10, it can be seen that the heating image HI is displayed as the background image as well as the heating intensity image PL and the changed timer image T 'at the center of the crater image FI for the heating element. .

In detail, the heating image HI may be displayed in a specific area of the input interface 300 where the crater image FI for the heating object is displayed, and may be repeatedly displayed in the form of a dynamic image. Accordingly, the heating image HI may be repeatedly reproduced in the input interface 300 in the form of a motion in which the color and shape of the flame are shaped while the working coil is being driven (that is, during the heating operation).

Through this, the user can visually easily recognize that the heating operation for the heating target object is currently in progress.

2, 3, and 11, a method of displaying the protection guide image is shown.

For reference, FIG. 11 is a diagram illustrating a schematic view of an input interface when a protection guide image is displayed.

In detail, as described above, 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 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 regarding 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 on 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 value, and compares the comparison result. On the basis of this, it is possible to control whether to display the protection guide image of the input interface 300.

In detail, when the analysis result is higher than a preset reference value, 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, while the protection guidance 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 received from the sensor 330 When the result of analyzing the information is lower than or equal to a preset reference value, the first control module 310 may control the input interface 300 to remove the protection guide image PGI displayed on the input interface 300. .

For reference, the analysis result may be a result of comprehensively analyzing numerical values of temperature and vibration of the input interface 300, and the preset reference value may also be a single value.

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

However, in an embodiment of the present invention, for convenience of description, the analysis result will be described by taking an example as a result of comprehensively analyzing the numerical values of the temperature and vibration of the input interface 300.

Based on the above-described method, as shown in FIG. 11, when the analysis result of the temperature and vibration of the input interface 300 is higher than a preset reference value, the protection guide image PGI is a conventional crater image for a heated object. (FI) may be displayed on the input interface 300 to overlap.

On the other hand, when the analysis result of the temperature and vibration of the input interface 300 is lower or equal to the preset reference value again, the protection guide image (PGI) displayed on the input interface 300 may be removed.

For reference, the protection guide image (PGI) may be displayed, for example, warning phrases such as 'Please put the cooking utensils on the screen', but is not limited thereto.

In addition, although not shown in the drawings, the zone-free induction heating apparatus 1 may be equipped with a speaker (not shown; that is, an acoustic module), and the first control module 310 may protect the speaker based on the comparison result. It can control whether or not the guide voice output.

That is, when the analysis result is higher than the preset reference value, the first control module 310 repeatedly repeats the protection guidance voice (for example, 'put the cooking utensils on the screen') for a preset number of times or time in the speaker. The speaker can be controlled to output.

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

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

As described above, when heat or vibration (ie, impact) is applied to the input interface 300, the protection guide image PGI is displayed in the pop-up form on the input interface 300. Damage to the interface 300 can be prevented in advance.

Subsequently, referring to FIGS. 2, 3, 12, and 13, a change in the image of the crater for the heated object according to the removal of the heated object is illustrated.

First, as shown in FIG. 12, when the heating element is disposed on the cover plate 119, the crater image FI and the power image PI for the heating element may be displayed on the input interface 300.

However, if the object to be heated is removed from the cover plate 119 before the heating operation is started, the crater image FI and the power image PI for the object to be heated may also be removed from the input interface 300.

That is, when the heated object detected at a specific position is not detected, the second control module 320 provides information to the first control module 310 that the heated object is not detected, and the first control module 310. The control unit 300 may control the input interface 300 to remove the crater image FI and the power image PI, which are displayed on the input interface 300, based on the received information.

On the other hand, as shown in FIG. 13, when the heating target is removed while the heating operation is being performed on the heating target placed on the cover plate 119, it is blurred during the hold setting time (ie, cooking hold setting time). The burned-up crater image FI ′ (of course, the heating intensity image PL and the timer image T also become blurred) may be displayed on the input interface 300. Of course, when the hold setting time has elapsed, the image of the burned-out crater image FI ′ may be removed from the input interface 300.

That is, when the heating object detected at a specific position is not detected while the heating operation is in progress, the second control module 320 provides information to the first control module 310 that the heating object is not detected. 1 The control module 310 may control the input interface 300 to blur the burner image FI for the heating object displayed on the input interface 300 based on the received information. In addition, when the hold setting time elapses, the first control module 310 may control the input interface 300 to remove the blurred image of the crater image FI ′ displayed on the input interface 300.

Lastly, referring to FIGS. 2, 3, and 14, there is shown a change in the image of the crater for the heated object according to the movement of the heated object.

Specifically, when the position of the heating target body is changed while the heating operation is performed on the heating target body disposed on the cover plate 119, the existing burner image FI for the heating target body is blurred image FI ′. The new crater image FI ″ may be displayed at the changed position.

At this time, the power image PI and the hold image LHI may be displayed in the center of the new burner image FI '', and the power image PI and the hold image LHI are tilted. Even when placed in a lower position, the vertical alignment may be displayed.
