Description

ZONE FREE TYPE INDUCTION HEATING DEVICE HAVING IMPROVED USER EXPERIENCE AND USER INTERFACE}

The present invention relates to a zone-free type induction heating device with improved user experience and user interface.

BACKGROUND OF THE INVENTION Various types of cooking utensils for heating food at home or in restaurants are being used. Conventionally, gas ranges using gas as fuel have been widely used, but recently, devices for heating a heating target object, for example, a cooking vessel such as a pot, using electricity without using gas have been spread.

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 an object to be heated by transferring heat generated when an electric current flows through a metal resistance wire or a non-metallic heating element such as silicon carbide to the object to be heated (eg, a cooking vessel) through radiation or conduction. In addition, the induction heating method uses a magnetic field generated around the coil when a high-frequency power of a predetermined size is applied to the coil to generate eddy current in an object to be heated made of metal components, thereby heating the object itself. am.

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

However, in recent years, an induction heating device (ie, a zone-free type induction heating device) that simultaneously heats one object with a plurality of working coils has been widely used. In the case of such a zone-free type induction heating device, an object to be heated can be induction heated regardless of the size and position of the object to be heated within an area where a plurality of working coils exist.

For reference, the Johnfree type induction heating device may include an input interface. Such an input interface is a module for inputting 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 also include a display panel for displaying a driving state of the induction heating device (ie, a touch screen type panel).

However, since the input interface of the conventional zone-free type induction heating device does not have a function to display residual heat, the user can know whether or not residual heat remains on the upper plate of the induction heating device (ie, the upper plate of the cover plate on which the object to be heated is placed). There was no

Accordingly, accidents in which users get burned due to residual heat remaining in the induction heating device frequently occur, and there is also a problem that it is difficult for users to efficiently use the induction heating device during cooking to prevent burns due to residual heat. .

In addition, in the case of the input interface of the conventional johnfree type induction heating device, when the working coil is operated, a crater is displayed at a position where the object to be heated is disposed. However, since only the set heating intensity and timer (ie, heating time) information are displayed on the corresponding cooking zone, it is difficult to visually identify whether or not the object to be heated is actually being heated through the corresponding cooking zone.

An object of the present invention is to provide a zone-free type induction heating device equipped with residual heat detection and display functions.

Another object of the present invention is to provide a John-Free type induction heating device that visualizes and displays a heating image.

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

The objects of the present invention are not limited to the above-mentioned objects, and other objects and advantages of the present invention not mentioned above can be understood by the following description and will be more clearly understood by the examples of the present invention. It will also be readily apparent that the objects and advantages of the present invention may be realized by means of the instrumentalities and combinations indicated in the claims.

A John-Free type induction heating device according to the present invention includes a temperature sensor for detecting the temperature of a cover plate, an input interface installed so as to be flatly buried on the upper surface of the cover plate and displaying a specific image, and a temperature of the cover plate from the temperature sensor. A first control module that receives information about the temperature of the cover plate and controls whether or not to display a residual heat image of the input interface based on the information about the temperature of the cover plate, and determines which working coil among a plurality of working coils is located on top of the object to be heated. By including a second control module for sensing, residual heat detection and display functions may be provided.

In addition, the John-Free type induction heating device according to the present invention is installed so as to be flatly buried on the upper surface of the cover plate, receives a touch input from a user, and receives a touch input from an input interface for displaying a specific image, A heating image may be visualized and displayed by including a first control module that controls the input interface to display a heating image on the input interface when the provided touch input is an input related to a specific heating intensity.

User experience and user interface may be improved by including a second control module that controls driving of the coil.

The zone-free type induction heating apparatus according to the present invention has a function of detecting and displaying residual heat, so that an accident in which a user gets burned due to residual heat can be prevented in advance. Furthermore, the user's cooking work efficiency may be improved by alleviating the user's concern about residual heat.

In addition, since the zone-free type induction heating device according to the present invention visualizes and displays a heating image, the user can visually and easily identify the fact that the object to be heated is being heated. Through this, there is no need to repeatedly check whether or not the object to be heated is properly heated, and thus convenience of use can be improved.

In addition, the case 125 may be insulated to prevent heat generated by the working coil WC from leaking to the outside.

On the other hand, the cover plate 119 is coupled to the top of the case 125 to shield the inside of the case 125, and to be heated (not shown; that is, at least one of a plurality of working coils (eg, WC)) An object heated by) may be placed on the upper surface.

In addition, the input interface 300 may also include a display panel displaying the operating state of the zone-free type induction heating device 1 .

For reference, the input interface 300 transfers the input provided from the user to the first control module 310, and the first control module 310 can transfer the input to the aforementioned second control module 320. Bar, the specific details about this will be described later.

The temperature sensor 330 may detect the temperature of the cover plate 119 .

In detail, the temperature sensor 330 may detect the temperature of the cover plate 119 and provide information about the detected temperature of the cover plate 119 to the first control module 310 .

The first control module 310 receives information about the temperature of the cover plate 119 from the temperature sensor 330, and the residual heat image of the input interface 300 based on the information about the temperature of the cover plate 119 provided. You can control the visibility.

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 a 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 to the input interface 300 based on the received touch input. You can control or choose which specific images are displayed.

Further, the first control module 310 may receive information about the location of the object to be heated from the second control module 320, and display the information on the input interface 300 based on the information about the location of the object to be heated. You can also control or select a specific image to be displayed.

On the other hand, the second control module 320 controls the driving of a plurality of working coils (eg, WC), and determines which of the plurality of working coils (eg, WC) an upper part of the heating target is located. can detect

Specifically, as described above, the second control module 320 may control the driving of the plurality of working coils (eg, WC) by controlling the inverter unit and components related to its driving. In addition, the second control module 320 may provide information about the detected location of the object to be heated 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 driving of the plurality of working coils (eg, WC) based on the user's touch input provided from the first control module 310 .

A plurality of working coils (eg, WC) may be provided inside the case 125 .

Specifically, a plurality of working coils (eg, WC) may be provided inside the case 125 and driven by the second control module 320 . That is, as shown in FIG. 2 , a plurality of working coils (eg, WCs) may be arranged to be spaced apart from each other by a predetermined interval.

Specifically, the working coil WC may be formed of a wire wound in an annular shape many times, and may generate an alternating magnetic field. In addition, a mica sheet and a ferrite core may be sequentially disposed below the working coil WC.

In addition, the ferrite core may be fixed to the mica sheet through a sealant, and may serve to diffuse 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 zone-free type 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 characteristics.

That is, recently, a technology for supplying power wirelessly has been developed and applied to many electronic devices. Electronic devices with wireless power transmission technology can charge their batteries simply by placing them on a charging pad without connecting a separate charging connector. An electronic device to which wireless power transmission is applied has advantages in that it does not require a wired cord or a charger, so portability is improved and its size and weight are reduced compared to the prior art.

These wireless power transfer technologies include 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 by 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. am.

Of course, the principle of the induction heating method of the John Free type induction heating device 1 is substantially the same as the wireless power transmission technology by electromagnetic induction in that the object to be heated is heated by electromagnetic induction.

Therefore, even in the case of the zone-free type induction heating apparatus 1 according to an embodiment of the present invention, a wireless power transmission function as well as an induction heating function may be installed. Furthermore, since the induction heating mode or the wireless power transmission mode may be controlled by the first control module 310, the induction heating function or the wireless power transmission function may be selectively used as needed.

As described above, the John Free type induction heating apparatus 1 according to an embodiment of the present invention has the above configuration and characteristics. Hereinafter, a method of controlling the John Free type induction heating apparatus 1 will be described. .

4 to 6 are schematic diagrams illustrating a method of detecting a heating target and displaying an image of a cooking zone. 7 to 9 are schematic diagrams illustrating a heating intensity and timer setting method. 10 is a schematic diagram illustrating a heating image. 11 is a schematic diagram illustrating a residual heat image. FIG. 12 is a schematic diagram illustrating a case in which a crater image for an object to be heated and a residual heat image are simultaneously displayed. 13 and 14 are schematic diagrams illustrating changes in the image of a cooking zone for an object to be heated according to the removal of the object to be heated. 15 is a schematic view illustrating a change in the image of a cooking zone for a heating target according to the movement of the heating target.

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

For reference, FIG. 2 is a diagram illustrating an actual appearance of the input interface 300 in which an image of a crater 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. FIG. 4 is a diagram illustrating a schematic appearance of the input interface 300 when a plurality of crater images for an object to be heated are displayed.

Specifically, when an object to be heated is placed on the upper plate portion 115 of the cover plate 119, the second control module 320 controls the object to be heated on top of one of the plurality of working coils (eg, WC). location can be detected.

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

To explain further, when a heating target is placed on a working coil (eg, WC), the total resistance may increase due to the resistance of the heating target, and as a result, the corresponding working coil (eg, WC) The degree of attenuation of the flowing resonance current may be increased.

The second control module 320 detects the resonant current flowing through the working coil (eg, WC) in this way, and detects whether or not there is an object to be heated on the working coil (eg, WC) based on the detected value is to do

Of course, the second control module 320 may detect the object to be heated through other methods, but in one embodiment of the present invention, detection of the object to be heated by the above method will be described as an example.

When the location of the object to be heated is sensed through this method, the second control module 320 may provide information about the location of the object to be heated to the first control module 310 .

In addition, the first control module 310 displays the image FI of the heating target object on the input interface 300 based on the information on the position of the object to be heated received from the second control module 320. ) can be controlled.

For reference, the input interface 300 includes, for example, as shown in FIG. 4 , a crater image FI for a heating object, a setting icon (eg, a temporary lowering icon, a button lock icon, a setting list icon, A setting image (SI) displaying a timer icon) and a secondary image (CI) displaying secondary icons (eg, automatic heating object detection status icon, Wi-Fi connection status icon, current time display icon) may be displayed. there is.

In addition, the crater image FI for the object to be heated may be displayed in a specific region of the input interface 300 to correspond to the position of the object to be heated on the cover plate 119, and the size and rotation direction of the object to be heated may be reflected and displayed. there is.

That is, based on the scale of the input interface 300 compared to the upper plate portion 115 of the cover plate 119, the image of the cooking area for the object to be heated is located in a specific region of the input interface 300 corresponding to the actual position of the object to be heated on the upper plate portion 115. (FI) may be indicated.

In addition, a power source image PI may be displayed at the center of the crater image FI for the object to be heated.

Accordingly, as shown in FIG. 5, before the object to be heated is disposed on the upper plate portion 115 while the power of the zone-free type induction heating device 1 is turned on, the input interface 300 displays the setting image SI. and only the auxiliary image CI may be displayed.

However, when an object to be heated is disposed on the upper plate 115 and its position is detected by the second control module 320, the image of the heating zone FI for the object to be heated and the power image PI are additionally displayed on the input interface 300. It can be.

Furthermore, as shown in FIG. 6, assuming that the total number of heatable objects is 6, when the 6 heated objects are disposed on the upper plate portion 115, six crater images for the heated objects (FI1 to FI6 ) may be displayed on the input interface 300 together with the power image.

However, if the 7th heating target is disposed on the upper plate 115 and exceeds the total number of heating targets, the 7th heating target image FI' may be dimly displayed and the power image may not be displayed. there is.

Accordingly, the 7th heating target image FI' becomes unselectable.

Next, referring to FIGS. 2, 3, and 7 to 9, a method of displaying a heating intensity image and a timer image is illustrated.

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

Specifically, the input interface 300 provides an input for touching the power image (PI of FIG. 4 ) to the first control module 310 when an input of touching the power image (PI of FIG. 4 ) is received from the user. can In addition, the first control module 310 displays the heating intensity image PL and the timer image T on the input interface 300 based on an input of touching the power image (PI in FIG. 4 ) provided from the input interface 300 . The input interface 300 may be controlled so that at least one is displayed.

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. Also, the heating intensity selection image PL PICKER may be displayed on the input interface 300 so that the heating intensity can be selected.

In this case, the user may provide an input related to a specific heating intensity (eg, an input of touching a heating intensity of 4.5) to the input interface 300 through a drag operation, and the specific heating intensity selected by the user may be It may be displayed on the intensity image PL.

For reference, even when the user provides only a specific heating intensity input to the input interface 300 without a timer input, the heating operation is automatically started when a preset time (eg, 3 seconds) elapses. can

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 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 perform a touch input related to a specific hour and minute value through a drag operation, and then set a timer by touching the 'OK' icon. Of course, the timer selected by the user can be counted after being displayed as the changed timer image T', and when the predetermined time has elapsed, the power image PI can be displayed again in the center of the burner image FI for the object to be heated. there is. In addition, when residual heat remains in the upper plate portion 115, the residual heat image RHI may also be displayed at the center of the crater image FI for the object to be heated.

Meanwhile, the input interface 300 may provide an input regarding a specific heating intensity to the first control module 310 when receiving an input regarding 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. 10, based on the input related to the specific heating intensity, the heating input interface 300 The input interface 300 may be controlled to display the image HI. Also, the second control module 320 may drive a working coil disposed at a position where an object to be heated 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. 10 , it can be seen that the heating image HI is displayed as a background image as well as the heating intensity image PL and the changed timer image T′ at the center of the heating target image FI. .

Specifically, the heating image HI may be displayed in a specific region of the input interface 300 where the crater image FI for the object to be heated is displayed, and may be repeatedly displayed in the form of a dynamic image. Accordingly, the heating image HI may be repeatedly reproduced on 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 in operation (ie, during heating operation).

Through this, the user can visually and easily recognize that a heating operation for the object to be heated is currently in progress.

Next, referring to FIGS. 2, 3, 11, and 12, a method of displaying a residual heat image is illustrated.

For reference, FIG. 11 is a diagram illustrating a real state of an input interface displaying a residual heat image, and FIG. 12 is a diagram illustrating a schematic state of an input interface when a residual heat image and a crater image for a heating target are simultaneously displayed.

Specifically, 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 . Also, the first control module 310 may receive information about the temperature of the cover plate 119 (ie, information about the temperature of the upper plate 115 ) from the temperature sensor 330 .

In addition, the first control module 310 may control whether to display a residual heat image on the input interface 300 based on information about the temperature of the cover plate 119 provided from the temperature sensor 330 . That is, when it is determined that residual heat remains in the cover plate 119, the first control module 310 may control the input interface 300 to display a residual heat image on the input interface 300.

Accordingly, as shown in FIG. 11 , when residual heat remains on the cover plate 119, the residual heat images RHI1 and RHI2 are displayed on at least one of the top of one side and the top of the other side of the input interface 300. can Of course, as described above with reference to FIG. 9 , the residual heat image (RHI of FIG. 9 ) may be displayed on the inner region of the crater image FI for the object to be heated.

However, for convenience of description, an example in which the residual heat images RHI1 and RHI2 are displayed on both the top of one side and the top of the other side of the top surface of the input interface 300 will be described as an example.

In addition to the case of FIG. 9 described above, the residual heat images RHI1 and RHI2 are displayed on the input interface 300 in the following cases.

First, it is a case where a user provides a touch input indicating the end of a working coil in operation among a plurality of working coils (eg, WCs) to the input interface 300 .

That is, in this case, the input interface 300 provides a corresponding input to the first control module 310, and the first control module 310 uses the corresponding input and information about the temperature of the cover plate 119 to cover the cover plate. The input interface 300 may be controlled to display the residual heat images RHI1 and RHI2 on the input interface 300 until residual heat is removed in step 119 .

Furthermore, when residual heat remains in the cover plate 119, the first control module 310 operates the input interface 300 until the residual heat is removed from the cover plate 119 based on the information about the temperature of the cover plate 119. is maintained, and when residual heat of the cover plate 119 is removed, the first control module 310 may turn off the input interface 300 based on information about the temperature of the cover plate 119 .

In addition, as shown in FIG. 12, among a plurality of working coils (for example, WC), the working coil disposed at the position where the object to be heated is detected is in an undriven state, and the crater images FI1 and FI2 for the object to be heated are Even when residual heat remains on the cover plate 119 in the state displayed on the input interface 300 (ie, activated state), the first control module 310 covers the cover plate 119 based on information about the temperature of the cover plate 119. The input interface 300 may be controlled to display residual heat images RHI1 and RHI2 on the input interface 300 until residual heat is removed from the plate 119 .

As described above, since residual heat images RHI1 and RHI2 are displayed on the input interface 300 in various situations, it is possible to prevent a user from being burned due to residual heat.

Subsequently, referring to FIGS. 2, 3, 13, and 14 , changes in the image of the cooking zone for the object to be heated according to the removal of the object to be heated are shown.

First, as shown in FIG. 13 , when an object to be heated is disposed on the cover plate 119 , a burner image FI for the object to be heated and a power image PI may be displayed on the input interface 300 .

However, if the corresponding heating target object is removed from the cover plate 119 before the heating operation starts, the cooking zone image FI for the heating target object and the power source image PI may also be removed from the input interface 300 .

That is, when the object to be heated that has been detected at a specific location is not detected, the second control module 320 provides information indicating that the object to be heated is not detected to the first control module 310, and the first control module 310 may control the input interface 300 to remove the cooking ball image FI for the object to be heated and the power source image PI displayed on the input interface 300 based on the provided information.

On the other hand, as shown in FIG. 14, when the heating target object disposed on the cover plate 119 is removed while the heating operation is in progress, the object is dimmed during the holding setting time (ie, the cooking holding setting time). A burned-out cooking zone image FI' for the object to be heated (of course, the heating intensity image PL and the timer image T are blurred) may be displayed on the input interface 300 . Of course, when the retention setting time elapses, the blurry cooking ball image FI' for the object to be heated may be removed from the input interface 300 .

That is, the second control module 320 provides information that the object to be heated is not sensed to the first control module 310 when the object to be heated is not sensed at a specific location while the heating operation is in progress. 1 The control module 310 may control the input interface 300 to blur the image FI of the heating target object displayed on the input interface 300 based on the provided information. In addition, when the retention setting time elapses, the first control module 310 may control the input interface 300 to remove the blurry cooking ball image FI' for the object to be heated displayed on the input interface 300 .

Lastly, referring to FIGS. 2, 3, and 15, changes in the image of the cooking zone for the object to be heated according to the movement of the object to be heated are shown.

Specifically, when the position of the heating target object disposed on the cover plate 119 is changed while the heating operation is in progress, the existing crater image FI for the heating target object becomes a blurry image FI' , and a new crater image FI for the object to be heated may be displayed at the changed position.

At this time, the power image PI and the holding image LHI may be displayed in the center of the new heating target image FI'', and the power image PI and the holding image LHI are tilted by the object to be heated. Even if they are arranged horizontally, they can be displayed aligned in the vertical direction.

That is, the second control module 320 transmits information about the newly changed position of the object to be heated to the first control module 310 when an object to be heated that has been detected at a specific location is detected at a different location while the heating operation is in progress. It is provided, and the driving coil that is being driven for the object to be heated may be stopped. In addition, the first control module 310 changes the existing cooking ball image FI for the heating target object displayed on the input interface 300 to a blurry image FI' based on the information provided, and a new heating target image FI is displayed at the changed position. The input interface 300 may be controlled to display the cooking ball image FI″.

Further, the user may select whether or not to maintain the existing cooking conditions (ie, heating intensity and cooking time (timer)) during the hold setting time (ie, cooking holding setting time). For reference, the hold setting time starts from the point at which the position of the object to be heated is changed, and may be previously set by the user.

If the user touch-inputs the holding image LHI, the existing heating intensity image PL and the changed timer image T' are displayed in the center of the new heating target image FI while maintaining, and cooking The work may also proceed with the existing heating intensity and timer value.

That is, when an input of touching the pending image LHI is received from the user, the input interface 300 may provide an input of touching the pending image LHI to the first control module 310 .

In this case, the first control module 310 maintains the existing heating intensity image PL and the changed timer image T' at the center of the new heating target image FI'' based on the received input. The input interface 300 may be controlled to be displayed.

In addition, the first control module 310 provides the received input to the second control module 320, and the second control module 320 moves the working coil disposed at the position where the object to be heated is newly sensed based on the received input. It can be driven based on the existing heating intensity and cooking time.

However, when the user touch-inputs the power image PI, the heating intensity image PL and the changed timer image T' are reset, and the reset heating intensity image PL, A timer image T and a heating intensity selection image PL PICKER may be displayed.

That is, when an input of touching the power image PI is received from the user, the input interface 300 may provide an input of touching the power image PI to the first control module 310 .

In this case, the first control module 310 resets the existing heating intensity image PL and the changed timer image T′ displayed in the center of the new heating target image FI based on the received input, and resets the The input interface 300 may be controlled so that the heating intensity image PL, the timer image T, and the heating intensity selection image PL PICKER are displayed on the input interface 300 .

On the other hand, if the user does not touch input both the hold image LHI and the power image PI during the hold set time, the hold image LHI is removed, and only the power image PI is a new cooking area image for the heating target ( FI″) can be displayed in the center.

Of course, even in this case, if residual heat remains, residual heat images RHI1 and RHI2 may be displayed on the input interface 300 .

In addition, when the retention setting time elapses, the blurry cooking ball image FI' for the object to be heated may also be removed from the input interface 300 .

That is, when the first control module 310 does not receive any input from the input interface 300 for the holding set time, the input interface 300 displays a new heating target image FI″ and power image PI. ) The input interface 300 may be controlled to display only.

Of course, when residual heat remains in the cover plate 119, the first control module 310 uses the input interface 300 until the residual heat is removed from the cover plate 119 based on information about the temperature of the cover plate 119. ), the input interface 300 may be controlled to display the residual heat images RHI1 and RHI2.
