Description

Induction range with available container notification {INDUCTION RANGE WITH CONTAINER NOTIFICATION FUNCTION}

The present invention is a technology related to an induction range capable of notifying usable containers. Specifically, when a user places a container on the induction range and attempts heating when using the induction range, the container can be used in the induction range. The present invention relates to a technology capable of improving convenience and intuitiveness of cooking through an induction range by allowing intuitive confirmation of whether or not the container is a container, and simultaneously notifying the heating state and fluid overflow due to the heating of the container.

The induction range is an appliance belonging to a heating tool among cooking tools, and is a cooking heating appliance using the principle of induction heating. When an alternating current flows through the coil under the heating object, an alternating magnetic field is formed according to the Ampere circuit law. This alternating magnetic field is concentrated toward the object to be heated with high magnetic permeability, and forms an eddy current in the object to be heated according to Faraday's law of induction. Joule heat is generated due to the eddy current and the resistance of the object to be heated, and food is cooked.

Compared to gas ranges, the induction range does not consume oxygen and can reduce indoor air pollution and increase indoor temperature because it does not discharge waste gas, and uses an indirect method that induces heat to the object to be heated, and has high energy efficiency and stability. However, since heat is generated from the container itself, but the contact surface is not heated, the risk of burns is low. In recent years, it has been widely used by replacing conventional electric ranges such as highlights and gas ranges or ranges using fossil fuels.

Since this induction range heats the container using the above-described induction heating principle, the container must contain a carbon steel component capable of generating heat in response to an eddy current generated by a magnetic field.

However, users who do not understand the principle of the induction range may try cooking by placing a container that does not contain carbon steel on the induction range. In this case, even if it is operated in the induction range, heating is not performed, and the inconvenience of use on the user's side has been pointed out, such as misunderstanding as a malfunction of the induction range.

In order to solve this problem, in Korean Patent Registration No. 10-1203114, etc., a technology for confirming whether the container is usable or not by sensing whether the iron component of the container is present through a self-reaction and displaying it on the display panel is provided. Is presented.

However, since the above-described prior art outputs container identification information on a separate display panel, there is a problem in that it is not possible to intuitively check whether a container is suitable in a multi-goal induction range in which a plurality of coils are patched at once. In particular, as information is continuously output during sensing through self-reaction, there is a problem that may cause fatigue of use to users.

Accordingly, the present invention is designed to solve the above-described problems, and it is possible to intuitively check for each container whether carbon steel is included in the container and can be used in the induction range even in a multi-gu type induction range, and at the same time, the operation time of the sensor It is an object of the present invention to provide a technology that can efficiently and efficiently display whether or not a container is suitable to users by efficiently controlling it.

In addition, in addition to the suitability of the above-described container, another object of the present invention is to provide a technology capable of improving the convenience of cooking by allowing detection of a heating state and overflow of fluid in the container during cooking through the container.

In order to achieve the above objects, in an induction range capable of notifying usable containers according to an embodiment of the present invention, an eddy current generated by a magnetic field induced by a coil installed under the base plate is placed on the top of the base plate. It relates to an induction range that heats a container by the resistance of carbon steel at the bottom of the container while passing through, and exists in the area where the coil is installed, and generates a magnetic field on the upper part of the base plate when power is supplied, and A first sensor for determining whether or not the object placed on the base plate contains a carbon steel component by detecting the change; A sensor driving unit that supplies power to the first sensor when power is supplied to the coil, and supplies power to the first sensor for a predetermined threshold time from a time when power is supplied to the coil; And a result output unit for outputting normal container notification information to a region of the base plate when it is determined that the object placed on the base plate contains a carbon steel component according to the magnetic field measured by the first sensor. It characterized in that it includes;

It is preferable that the result output unit outputs normal container notification information during the critical time when power is supplied to the first sensor by the sensor driving unit.

The result output unit is disposed in a position adjacent to the region where the coil is installed, and when it is determined that the normal container is mounted, the light emitting unit that emits light is supplied with power and is installed in a region of the base plate to indicate that the normal container is mounted. When it is determined, it is preferable that it is at least one of the speakers that receive power and output sound.

The result output unit, when the amount of change in the magnetic field measured by the first sensor exceeds a threshold amount of change, determines that the object placed on the top of the base plate is usable in the induction range, and outputs the normal container notification information. Do.

It is preferable that a plurality of the coils are installed on the base plate, and the first sensor and the result output unit are installed for each of the coils.

A second sensor for sensing the state information of the content in the object placed on the coil; further comprising, the result output unit, the main output unit for outputting the normal container notification information and the state of the content determined by the second sensor It is preferable to include a sub-output unit that outputs different information to indicate the information.

The second sensor includes at least one of a vibration sensor for measuring a degree of vibration of the contents according to the heating of the contents and a fluid detection sensor for detecting whether a part of the contents is present on the base plate by overflowing the contents from the object. It is desirable to do it.

In the present invention, the induction range 1 is carbon steel at the bottom of the container while the eddy current generated by the magnetic field induced by the coil installed under the base plate passes through the bottom of the container placed on the base plate as described above. It means a device that heats the container by the resistance of.

As shown in FIG. 1, the coil 20 generating the eddy current is installed under the base plate 10, and the base plate 10 is preferably made of a material that passes the eddy current generated by the coil 20. Do. In addition, as shown in FIG. 1, a plurality of coils 20 are installed on the base plate 10 to function as a multi-spherical range. That is, the container 100 is placed on top of each coil 20, and the drive is controlled through the switch panel 2 for each coil 20, so that a plurality of containers 100 can be heated at once. It becomes.

The switch panel 2 is implemented in various ways, such as a button, a dial, and a touch type, and is a component capable of inputting to control power supply to a plurality of coils 20. The switch panel 2 is connected to a computing device (not shown) that controls the entire driveable configuration of the induction range 1, which may include a sensor driving unit 62 and a power control unit 61 to be described later, and the input signal described above. May be configured to be delivered to the computing device. The input signal of the switch panel 2 may be transmitted to the power control unit 61 described above, so that power supply from the power supply unit 60 to the coil 20 may be controlled. Although the switch panel 2 is shown to be installed on the main body in FIG. 1, it may be implemented to be installed on the base plate 10 according to an embodiment of the present invention.

The coil 20 is installed in each container arrangement area, and when it is installed under the base plate 10 to receive power from the power supply unit 60, it is a configuration that performs a function of forming an eddy current according to the above-described principle. .

The first sensor 30 exists in the area where the coil 20 is installed, and generates a magnetic field on the top of the base plate 10 when power is supplied, and detects a change in the magnetic field, thereby being placed on the top of the base plate 10. It performs a function of determining whether the object, that is, the container 100 contains a carbon steel component.

At this time, it can be understood that the function of determining whether the carbon steel component is included is programmed and performed in the result output unit 40 and the computing device including the same, and at this time, the first sensor 30 is a magnetic field as described below. It can be understood as performing a function of sensing the change value of and transmitting it to the result output unit 40 and a computing device including the same, and performing a function of determining whether the container 100 contains a carbon steel component. .

A specific example of the structure of the first sensor 30 is as shown in FIG. 4. That is, the first sensor 30 may be composed of a magnetic field generating unit 31 and a magnetic field measuring unit 32, wherein the magnetic field generating unit 31 is configured to form a magnetic field M1 when power such as an electromagnet is supplied. It will be understood, and the magnetic field measuring unit 32 will be understood as a configuration that performs a function of measuring the surrounding magnetic field M2. Meanwhile, as shown in FIG. 1 and the like, the first sensor 30 is preferably disposed in the center of an area on which an object such as the container 100 is placed, but it will not be limited thereto.

As soon as the container 100 is raised and power is supplied to the coil 20 by the switching panel 2, the magnetic field is formed while the same power is supplied to the magnetic field generator 31 of the first sensor 30, At this time, when carbon steel is not included in the container, and when resistance is applied to the eddy current because carbon steel is included, the magnetic field value is different, and the first sensor 30 measures the value of the corresponding magnetic field, and thus the container 100 ) Is to determine whether it contains a carbon steel component.

At this time, when power is supplied to the coil 20, the sensor driver 62 supplies power to the first sensor 30 as described above, but for a predetermined threshold time from the time when power is started to be supplied to the coil 20. It performs a function of supplying power to the first sensor 30.

Implementing the first sensor 30 with an electromagnet as described above without configuring a permanent magnet creates a magnetic field while supplying power to the coil 20 so that heating according to the eddy current is performed in the container 100. This is to not affect the eddy current by the magnetic field generated by the magnet. In addition, the first sensor 30 is implemented as an electromagnet as described above, and the first sensor 30 is supplied with power from the moment power is supplied to the coil 20 to form a magnetic field in an electromagnet manner. It is to determine whether the container 100 can be used for the induction range 1 at the moment power is supplied to (20).

In addition, supplying power to the first sensor 30 only for a predetermined critical time as described above is to eliminate an increase in user fatigue due to excessively long output of the result of determining the suitability for use for the container 100. .

Result output unit 40, according to the magnetic field measured by the first sensor 30, when it is determined that the object placed on the top of the base plate 10 contains a carbon steel component, It performs the function of outputting normal container notification information in one area.

Specifically, since power is supplied to the first sensor 30 for a critical period of time as described above to form a magnetic field, the critical time when power is supplied to the first sensor 30 by the sensor driver 62 in the same manner. It can be implemented to output the normal container notification information during.

Specifically, as shown in FIG. 1, the result output unit 40 is disposed at a position adjacent to the area where the coil 20 is installed, and when it is determined that the normal container is mounted, the light emitting unit 41 that emits light by receiving power is supplied. ) And a speaker 42 that receives power and outputs sound when it is determined that a normal container is mounted on a region of the base plate 10 or the main body.

At this time, the light emitting part 41 preferably surrounds the outer surface of the coil 20 as shown in FIG. 1, that is, when the container 100 is raised, the base plate of the area surrounding the bottom surface of the container 100 ( 10) It can be implemented with an LED or optical fiber installed at the bottom.

There may be a threshold value for the content of carbon steel in the container 100 that can be used in the induction range 1, and accordingly, the result output unit 40, the amount of change in the magnetic field measured by the first sensor 30 When exceeding the threshold change amount, it is preferable to determine that the object placed on the base plate 10 is usable in the induction range 1, and output the normal container notification information.

That is, when power is supplied to the first sensor 30 after the container 100 is raised and the magnetic field generated by the container 100 is changed and sensed, the result output unit 40 compares the change amount with the critical change amount. Thus, it is determined whether or not the normal container notification information is output.

At this time, the light emitting unit 41 is, for example, the moment when power is supplied to the coil 20 according to the operation of the switching panel 2, after the container 100 is mounted on the coil 20 as described above. 1 When it is determined that the object, that is, the container 100 is usable in the induction range 1 according to the sensing value of the sensor 30, it is configured to output a display effect such as a blue flame, and intuitively, the light emitting unit 41 ) It may be implemented so that the user can determine whether the container 100 placed in the center can be used normally in the induction range 1.

Meanwhile, as described above, in the multi-spherical range, a plurality of coils 20 may be disposed. In this case, in order to immediately determine which container 100 can be used by applying the above-described implementation example, the first sensor ( 30) and the result output unit 40 are preferably installed for each of the coils as shown in FIG. 1.

Meanwhile, in the present invention, not only whether the container 100 is normally available, but also the object during cooking, that is, the state information of the contents in the container 100 are sensed and output together to provide convenience during cooking.

To this end, in another embodiment of the present invention as shown in FIGS. 5 and 6, the induction range 1 further includes second sensors 33 and 34 for sensing state information of the contents of the object placed on the coil. In this case, the result output unit 40 may display different information to indicate the state information of the contents determined from the main output unit 41 and the second sensors 33 and 34 that output normal container notification information. It may be configured to include sub-output units 43 and 44 that output.

At this time, as shown in FIG. 5, the second sensors 33 and 34 have a vibration sensor 33 that measures the degree of vibration of the contents according to the heating of the contents, and the contents are overflowed from the object and are placed on the upper part of the base plate 10. It may include at least one of the fluid detection sensors 34 that detect whether a part of the contents is present.

The vibration sensor 33 is specifically a sensor that measures the fine vibration of the container 100. When the contents of the container 100 are heated, vibration is generated by a phenomenon such as boiling water according to an increase in molecular mobility, which will be transmitted to the container 100. The vibration sensor 33 measures the vibration value f of the vibration transmitted to the container 100, and the result output unit 40 receives the vibration value and uses a pre-generated algorithm to heat the fluid. And the sub output unit 43 is driven through a control value generated according to the heating degree, and outputs the value so that the heating degree of the contents can be recognized.

Meanwhile, the fluid detection sensor 34 may be implemented as various types of sensors capable of determining whether a fluid is present on the upper surface of the sensor, such as an optical sensor that measures refraction by the fluid. It is possible to sense whether a content such as a fluid is partially overflowed from the container 100. In this case, the sub output unit 44 may output information indicating that the object has overflowed visually as shown in FIG. 6 or as audio using the speaker 42 described above.

As described above, although the embodiments have been described by the limited embodiments and drawings, those of ordinary skill in the art will understand that various modifications and variations are possible from the above description. The terms such as "include", "comprise" or "have" described above mean that components without a description to the contrary may be included, and thus other components are not excluded.
