Description

Induction range {INDUCTION RANGE}

The present invention relates to an induction range, and more specifically, by forming a predetermined light emission pattern on the upper surface of the induction range, it can serve as an indicator to inform the user of the operating status of the induction range, safety information, guidelines, etc. This is about an induction range.

An induction range (or induction cooker) is a home appliance that generates heat by reacting with a container made of electrically conductive material using a magnetic field generated within the device, rather than generating its own heat. Recently, the demand for induction ranges has been increasing for design and safety reasons. In particular, demand for portable induction ranges that can be used in single-person households and camping is increasing.

FIG. 1 is a diagram for explaining the structure of a general induction range, and FIG. 2 is a diagram showing the internal structure of the general induction range main body shown in FIG. 1.

Referring to Figures 1 and 2, a working coil tightly surrounded in a circle is disposed inside the main body of the induction range. When a high-frequency alternating current is passed through a circular working coil, an alternating magnetic field whose direction changes at any time is created. When an iron (Fe) conductor such as a frying pan that conducts electricity well is placed on top of this magnetic field, an eddy current, or eddy current, is formed. Eddy currents formed in conductors such as frying pans collide when they meet the electrical resistance of the metal. The collision of eddy currents and electrical resistance creates an induction heating phenomenon that converts electrical energy into thermal energy, and through this, the conductors of cooking utensils such as frying pans placed on the upper surface of the induction range become hot, allowing cooking.

The advantage of an induction range is that it transfers energy directly to the cooking utensil, so there is no heat loss, cooking time is shortened, no harmful gases are emitted, and the top does not heat up, so it is relatively free from fire, burns, and contamination. Additionally, even if you place raw eggs or chocolate on an induction range that is turned on, they will not cook or melt. Except for the heat that is transferred from the bottom of the cookware to the glass surface (directly underneath the cookware), the surface remains cold.

Meanwhile, the disadvantages of induction ranges are that non-conductive cooking utensils such as earthenware pots and glass cannot be used, and it is difficult for users to check the thermal power of the induction range with the naked eye.

Figure 3 is a diagram for explaining an induction range product according to an example of the prior art.

Referring to FIG. 3, due to the nature of conventional induction range products, fire does not actually exist and is not visible to the naked eye, so a seating guide line (GL) of the cooking appliance is displayed on the surface of the top plate of the induction range. This seating guideline (GL) is visible even when the induction range is not operating. Additionally, conventional induction range products inform the user of the level of heating power through the LED on the control panel located at the edge of the top plate.

Figure 4 is a diagram for explaining an induction range product according to another conventional example.

Referring to FIG. 4, a conventional induction range product has individual LEDs placed on the top plate to create a 'virtual flame' during operation. The virtual flame is illuminated on the surface of the cooking utensil 1 placed on the top plate, allowing the user to know the level of heating power of the induction range.

Figure 5 is a diagram for explaining an induction range product according to another example of the related art.

Referring to Figure 5, in conventional induction range products, due to the nature of the induction range, the fire does not actually exist and is not visible to the naked eye, so the seating guide line (GL) of the cooking appliance is displayed on the surface of the top plate of the induction range, and the induction range The seating guide line (GL) is visible even when it is not operating. In addition, conventional induction range products display information such as the degree of heating power to the user through an operation dial and LED display window located at the bottom of the side.

Figure 6 is a diagram for explaining the structure of an induction range according to an embodiment of the present invention.

Referring to FIG. 6, an induction range according to an embodiment of the present invention includes a main body 100 and a lighting top member 300.

The main body 100 houses a working coil that generates magnetic force lines and a driving circuit for driving the working coil. The main body 100 may include a power supply unit and a control unit. The power unit receives a power signal from the outside and supplies power to the electronic components, and the control unit may include a power switch, a heat power controller, a food cooking mode selector, etc. In addition to the components described above, the main body 100 may further accommodate a number of electronic components for performing various functions of the induction range.

The outer shape of the main body 100 may have various shapes, for example, a hexahedron or a cylinder.

The lighting top member 300 is disposed on the main body 100 and supports at least one cooking utensil disposed thereon.

The lighting top member 300 receives light from one side and emits the light L only in the upper direction. The light (L) emitted from the lighting top member 300 can be used to convey information or as a safety warning, and can implement cookware guidelines and a specific logo (eg, manufacturer).

The lighting top member 300 includes a light source unit 310, a light emitting member 330, and a cover member 350.

The light source unit 310 provides light to the unidirectional light emitting member 330. The light source unit 310 is disposed on at least one side of the unidirectional light emitting member 330. The light source unit 310 may be an LED, but is not limited thereto.

The plurality of light emitting elements of the light source unit 310 may emit light toward the center of the circular light emitting member 330 and the cover member 350.

Referring to (b) of FIG. 7, a light source unit 310' may be disposed around the rectangular light emitting member 330' and the cover member 350'. The plurality of light emitting elements of the light source unit 310' may emit light toward the center of the square light emitting member 330' and the cover member 350'.

Referring to Figures 7 (a) and (b), the light source units 310 and 310' are not arranged directly, but have a structure in which a plurality of LEDs, which are light emitting elements, are arranged on the sides. Multiple light-emitting devices can display a variety of colors by using RGB LEDs. Power supply to the LED can be provided from an induction range. The LED can be hidden from the outside by the body 100 shown in FIG. 6.

The induction range may include a control unit for driving and controlling a plurality of light emitting devices. The control unit can control the on/off and output intensity of each light-emitting device, and can individually control the RGB LED to emit light of a predetermined color through the lighting top member 300.

FIG. 8 is a photograph showing the state when the lighting top member 300 shown in FIG. 7 is actually manufactured and the light source unit 310 is turned off and turned on.

Referring again to FIG. 6, the light emitting member 330 is disposed on the main body 100, receives light from the light source unit 310, and emits it to the outside through the upper surface.

The light emitting member 330 may be made of UV curable resin. Alternatively, the light emitting member 330 may be made of a highly heat-resistant material such as silicone rubber (PDMS) or TPU (Thermoplastic Polyurethane).

The lower surface of the light emitting member 330 includes a cavity 335 for reflecting the light provided from the light source unit 310 to the upper surface. The cavities 335 may have an engraved pattern, and a plurality of cavities 335 may be arranged on the lower surface of the unidirectional light emitting member 330. The structure of the cavity 335 will be described in detail with reference to FIGS. 9 and 10 .

FIGS. 9 and 10 are drawings for explaining in detail the cavity 335 of the unidirectional light emitting member 330 according to an embodiment of the present invention.

The cavity 335 has a predetermined depth h from the lower surface of the unidirectional light emitting member 330. Cavity 335 may also be referred to as a groove. Here, the depth (h) may be 1 μm or more and 100 μm or less.

As the depth h increases, the width of the cross-section of the cavity 335 (here, the cross-section is a virtual shape that vertically cuts the light exit part while passing through the central axis C of the cavity 335). side.) becomes narrower. Here, the cross-section of the cavity 335 may have a trapezoidal shape, and the angle (θ) between the lower side and the side side of the trapezoidal cross-section may be greater than 0 (°) and less than 90 degrees (°). Meanwhile, although not shown in a separate drawing, the side of the trapezoidal cross-section may be a curve rather than a straight line, and in the case of a curve, the side of the trapezoidal cross-section may be a curve with a predetermined radius of curvature inside the trapezoidal cross-section.

The cavity 335 may be defined by a bottom located at a predetermined depth from the opening and inner surfaces connected to each side constituting the bottom. The cavity 335 becomes narrower from the opening to the bottom surface. Here, the inner surfaces of the light emitting member 330 are composed of three or more, each side of the bottom surface is a convex curve in the inner direction of the cavity 335, and at least one of the inner surfaces is curved in the inner direction of the cavity 335. It may be a convex curved surface. Here, each side of the bottom surface and the curved inner surface may have a predetermined radius of curvature, and the curvature of each side of the bottom surface and the radius of curvature (R) of the inner surface may be the same or different. The planar shape of the cavity 233c' may be a polygonal closed curve with a radius of curvature (R) in the range of 100 nm to 1 mm.

The cavity 335 may be formed by imprinting the lower surface of the light emitting member 330.

Since the light emitting member 330 has a cavity 335 with a concave light emitting pattern, light incident at various angles from the plurality of light source units 310 can be reflected in a direction substantially perpendicular to the light emitting member 330, thereby allowing light to exit. There is an advantage in that the characteristics are improved.

Referring again to FIG. 6, the cover member 350 is disposed on the unidirectional light exit member 330. The cover member 350 transmits the light provided from the unidirectional light emitting member 330 and emits it to the outside.

The cover member 350 may be made of a transparent material such as glass. Therefore, no matter what color is placed under the cover member 350, it is possible to harmonize with that color. That is, the background under the cover member 350 is clearly revealed.

The cover member 350 may be made of a material with high insulation and durability, such as tempered glass, low iron tempered glass, heat-resistant tempered glass, and transparent ceramic glass. Here, the ceramic glass is made of porcelain, is called glass because it is as transparent as glass, and can withstand temperatures up to 700 degrees Celsius.

One or more cooking utensils are disposed on the upper surface of the cover member 350.

Figure 11 is a diagram for explaining the structure of an induction range according to another embodiment of the present invention.

The induction range shown in FIG. 11 differs from the induction range shown in FIG. 6 in the lighting top member 300' and the rest is the same.

The lighting top member 300' of the induction range shown in FIG. 11 includes a film member 370. The film member 370 may be a reflective film or an insulating film.

The reflective film can improve light extraction efficiency by reflecting leaked light that does not enter the light emitting member among the light emitted from the light source portion of the lighting top member 300'.

The insulation film can block heat emitted from the light source portion of the lighting top member 300' from flowing into the main body 100.

FIG. 12 is a diagram for explaining an application example of the induction range according to the embodiment of the present invention shown in FIG. 6 or FIG. 11.

In the application example shown in FIG. 12, light of different colors is emitted from the lighting top members 300 and 300' depending on the thermal power.

Through this, the induction range user can recognize the current thermal power status through the color of light emitted from the lighting top members 300 and 300'. Alternatively, the color of the light emitted from the lighting top member (300, 300') is controlled depending on the food cooking mode (soup - red, grilled fish - orange, fried egg - yellow), so the user can recognize the food cooking mode through color. there is.

FIG. 13 is a diagram for explaining another application example of the induction range according to the embodiment of the present invention shown in FIG. 6 or FIG. 11.

In the application example shown in FIG. 13, light of different colors is emitted from the lighting top members 300 and 300' depending on the safety situation.

Referring to FIG. 13, when a plurality of light emitting elements of the light source included in the lighting top members 300 and 300' are composed of RGB LEDs, the current state of the induction range is unsafe for the user, for example, the top panel In this overheated situation or improper operating situation (if the cooking utensil is not a container exclusively for induction range or the cooking utensil is not placed on the upper plate), the lighting upper plate member (300, 300') may emit red light. there is. Through this, the induction range user can recognize the current safety situation of the induction range through the color of light emitted from the lighting top members 300 and 300'.

Figure 14 is a diagram for explaining another application example of the induction range according to the embodiment of the present invention shown in Figure 6 or Figure 11.

In the application example shown in FIG. 14, light corresponding to a predetermined logo or cooking utensil seating guideline is emitted from the lighting top members 300 and 300'.

Referring to FIG. 14, when the induction range is operated, the lighting top members (300, 300') emit light corresponding to the induction range manufacturer's logo (MEMSLUX), safety warning logo (CAUTION), and cookware seating guide line (GL). It can be released. In addition, as shown on the far right of FIG. 14, when the induction range is turned on, a certain logo is always turned on so that the user can recognize whether the induction range is turned on through the logo.

In order to form a specific logo (MEMSLUX, CAUTION) or seating guide line (GL) in the lighting top member (300, 300') through light, a plurality of cavities of the light emitting member of the lighting top member (300, 300') are described above. It can be implemented by forming only the part that corresponds to a specific logo or the seating guideline. A detailed description of this will be provided later with reference to FIG. 15.
