Description

Induction heating cooking apparatus and method of displaying cooking information thereof

Technical Field

The following embodiments relate to an induction heating cooking apparatus and a method of displaying cooking information of the induction heating cooking apparatus, and more particularly, to an induction heating cooking apparatus for providing cooking information to a user using a reflector disposed inside the induction heating cooking apparatus and a method of displaying cooking information of the induction heating cooking apparatus.

Background

Induction heating cooking apparatuses are electronic devices for heating and cooking food using induction heating. Induction heating is a method of converting electric energy into heat energy and heating food by electromagnetic induction.

A coil (or work coil) that generates a magnetic field by applying an electric current under a metal cooking vessel (e.g., a pot, etc.) may be positioned. The magnetic field generated in the coil induces a secondary current in the metal cooking vessel. The induced secondary current causes the food ingredients to be heated and cooked using joule heat generated in the metal cooking vessel.

The induction heating cooking apparatus can be heated more quickly and reduce the generation of harmful gas, compared to a cooking apparatus for heating a cooking container (or a metal cooking container) using combustion heat of fossil fuel.

One surface of the top plate 120 (e.g., the bottom surface of the top plate 120 facing the bottom surface 110b of the body 110) may be painted black or other color. Some regions on one surface of the top plate 120 may be colored black, and regions other than the some regions may be colored gray. One surface of the top plate 120 may be divided into a plurality of regions, and the divided regions may be painted with various colors.

When the bottom surface of the top plate 120 is painted black or another color, the user can recognize (or recognize) cooking information (including operation state information) of the induction heating cooking apparatus 100 reflected (or projected, imaged, etc.) from the reflector 145. However, due to the coloring of the top plate 120, components disposed inside the main body 110 of the induction heating cooking apparatus 100 may not be distinguished from the outside. Further, the top plate 120 may be partially painted black.

Some regions of the bottom surface of the top plate 120 (e.g., the gap regions 120 a) may be transparent (e.g., not black-painted). The user can recognize cooking information (including operation state information) reflected (or projected, imaged, etc.) from the reflector 145 through the gap region 120 a. The gap region 120a may be implemented in a location that enhances visibility of cooking information (including operating state information) reflected (or projected, imaged, etc.) from the reflector 145.

The body 110 may have an opening 110a and a bottom surface 110 b. The inverter 165, the cooling unit 166, the fan 167 (see fig. 2), and the power supplier 170 (see fig. 2) may be respectively coupled to the bottom surface 110 b.

A processor (or microcontroller) 161 of the control board 160 may control one or more of the work coil 130, the projector 140, the control panel 148, the inverter 165, the cooling unit 166, the fan 167, and the power supply 170.

Referring to fig. 4a to 5b, a cooking information display 149 of the induction heating cooking apparatus 100 is shown. In fig. 4a and 5a, the cooking information display 149 may include a projector 140 and a planar reflector 145 a. In fig. 4b and 5b, the cooking information display 149 may include a projector 140 and a curved reflector 145 b.

In fig. 4a and 5a, the planar reflector 145a may be disposed at a first predetermined distance L1 (e.g., 150 mm, a distance that may be varied by a manufacturer) from the projector 140. The first predetermined distance L1 may correspond to at least one of a size of the projector 140 and a distance between the work coil 130 and the projector 140. In addition, the first predetermined distance L1 may vary depending on the lens performance in the projector 140 or the structure of the optical system.

A portion of the projector 140 may be disposed through the opening 111 a. The opening 111a may be formed in consideration of a portion through which the projector 140 passes.

The angle θ 1 may be generated between the optical axis 140c of the projector 140 and the planar reflector 145a because the coupling position of the planar reflector 145a (e.g., the coupling position with the control board or the coupling position with the main body) is different from the coupling position of the projector 140. The angle θ 1 may be generated between the optical axis 140c of the projector 140 and the planar reflector 145a because the coupling positions of the projector 140 coupled with the control board 160 and the planar reflector 145a coupled with the partition 111 are different from each other.

The angle θ 1 that can be generated between the optical axis 140c of the projector 140 and the planar reflector 145a can be 5 degrees or less. The angle θ 1 that may be generated between the optical axis 140c of the projector 140 and the planar reflector 145a may be greater than 3 degrees and less than 10 degrees. The angle θ 1 between the optical axis 140c of the projector 140 and the planar reflector 145a may be expressed as an angle between the highest position 146t (or the maximum height) of the cooking information 146 (including the operation state information) of the induction heating cooking apparatus 100 reflected (or projected, imaged, etc.) by the planar reflector 145a or an angle between the lowest position 146b (or the minimum height) of the cooking information 146 (including the operation state information) of the induction heating cooking apparatus 100 reflected (or projected, imaged, etc.) by the planar reflector 145 a.

The planar reflector 145a is inclined at 90 degrees with respect to the bottom surface 110b of the body 110. The planar reflector 145a is greater than 88 degrees and less than 93 degrees relative to the bottom surface 110b of the body 110.

The planar reflector 145a may be spaced apart from an outermost work coil 130w of the work coils 130 by a second predetermined distance L2 (e.g., 25 mm, a distance that may vary by manufacturer). The first predetermined distance L1 is greater than the second predetermined distance L2.

The width w of the planar reflector 145a may vary according to the diameter of the work coil 130. For example, when the diameter of the work coil 130 is 240 mm, the width w of the planar reflector 145a may be 240 mm or less than 240 mm. When the diameter of the work coil 130 is 180 mm, the width of the planar reflector 145a may be less than 180 mm or 180 mm. In addition, the width w of the planar reflector 145a may be larger than the diameter of the work coil 130.

The width w of the planar reflector 145a may be greater than the width of the cooking information 146 (including the operation state information) of the induction heating cooking apparatus 100 output from the projector 140. For example, when the width of cooking information (including operation state information) of the induction heating cooking apparatus 100 is 200 mm, the width w of the planar reflector 145a may be greater than 200 mm.

The height h1 of the planar reflector 145a may be changed according to the height of the inverter 165 under the partition 111. For example, the height h1 of the planar reflector 145a may be less than 15 mm or 15 mm. The thickness t1 of the planar reflector 145a may be less than the height h1 of the planar reflector 145 a. For example, the thickness t1 of the planar reflector 145a may be 10 mm or less. Further, the thickness t1 of the planar reflector 145a may be less than 15 mm.

The material of the planar reflector 145a may be a heat-resistant material because it is disposed near the cooking container 1 heated to a high temperature. The material of the planar reflector 145a may include, for example, aluminum, stainless steel without iron, heat-resistant injection plastic, heat-resistant silicone, or heat-resistant rubber. The heat resistant injection plastic may include polycarbonate, polyamide, polyphenylene sulfide, and the like. The material of the planar reflector 145a is merely an example, and a heat-resistant material is sufficient. The surface of the planar reflector 145a (e.g., facing the projector) may be coated with a white, silver, or neutral reflective coating (e.g., silver or TiO 2). In addition, the surface of the planar reflector 145a may be adhered to the same coating or film as the surface material of the roll screen.

Cooking information (including operation state information) of the induction heating cooking apparatus 100 may be reflected at the front surface 14a1 of the planar reflector 145 a. The front surface 145a1 of the planar reflector 145a may be treated with a film (not shown) or coated (not shown) to improve visibility of cooking information (including operating state information) of the induction heating cooking apparatus 100. In addition, cooking information (including operation state information) of the induction heating cooking apparatus 100 may be projected or imaged from the front surface 145a1 of the planar reflector 145 a.

All or a portion of the plurality of light sources may be controlled. The portion of the plurality of light sources may include a single light source in the total light source or a group light source (which is less than 75% of the total light source) that is a set of single light sources.

The virtual flame output from the virtual flame generator may be transmitted through the black-painted refractory top plate 120 or may be transmitted to the black-painted refractory top plate 120 through a separate gap region (not shown) implemented in correspondence with the virtual flame generator.

The user can change the virtual flames such as the size, color, brightness, or lighting speed of the virtual flames according to the input of the increase/decrease buttons 148c1 and 148c2 of the control panel 148. The brightness and degree of flicker of the virtual flame may be changed similarly to the actual flame.

In fig. 4b and 5b, the curved reflector 145b may be disposed at a first predetermined distance L1-1 (e.g., 150 mm, a distance that may be varied by a manufacturer) from the projector 140.

The first predetermined distance L1-1 in fig. 4b and 5b is substantially similar to the first predetermined distance L1 in fig. 4a and 5a (e.g., difference of reflectors), and thus redundant description is omitted. The opening 111a in fig. 4b and 5b is substantially similar to the opening 111a in fig. 4a and 5a (e.g., difference of reflectors), and thus redundant description is omitted.

The angle θ 2 that may be generated between the optical axis 140c of the projector 140 and the planar reflector 145b in fig. 4b and 5b corresponds to the angle θ 1 (e.g., difference of reflectors) that may be generated between the optical axis 140c of the projector 140 and the planar reflector 145a in fig. 4a and 5a, and thus redundant description is omitted.

The curved reflector 145b may be spaced apart from an outermost one of the work coils 130w by a second predetermined distance L2-1 (e.g., 25 mm, a distance that may be varied by a manufacturer). The first predetermined distance L1-1 is greater than the second predetermined distance L2-1.

Arc of curved reflector 145blMay vary depending on the diameter of the work coil 130. For example, when the diameter of the work coil 130 is 240 mm, the arc of the curved reflector 145blMay be 240 mm or greater than 240 mm. When the diameter of the work coil 130 is 180 mm, the arc of the curved reflector 145blMay be greater than 180 mm or 180 mm.

The height h2 of the curved reflector 145b may vary depending on the height of the inverter 165 below the partition 111. For example, the height h2 of the curved reflector 145b may be less than 15 mm or 15 mm. The thickness t2 of the curved reflector 145b may be less than the height h2 of the curved reflector 145 b. For example, the thickness t2 of the curved reflector 145b may be 10 mm or less. Further, the thickness t2 of the curved reflector 145b may be less than 15 mm.

The material of the curved reflector 145b in fig. 4b and 5b is substantially similar to that of the planar reflector 145A in fig. 4a and 5A (e.g., difference in shape), and thus redundant description is omitted.

Cooking information (including operation state information) of the induction heating cooking apparatus 100 may be reflected at the front surface 145b1 of the curved reflector 145 b. The front surface 145b1 of the curved reflector 145b may be treated with a film (not shown) or coated (not shown) to improve visibility of cooking information (including operating state information) of the induction heating cooking apparatus 100. In addition, cooking information (including operation state information) of the induction heating cooking apparatus 100 may be projected or imaged from the front surface 145b1 of the curved reflector 145 b.

The shock absorbing material 147-1 between the curved reflector 145b and the top plate 120 in fig. 4b and 5b is substantially similar to the shock absorbing material 147 (e.g., difference in reflectors) between the flat reflector 145a and the top plate 120 in fig. 4a and 5a, and thus redundant description is omitted.

The virtual flame generator (e.g., a plurality of light sources, a plurality of lenses corresponding to the plurality of light sources, and a light source and a lens holder, etc.) in fig. 4b and 5b is substantially similar to the virtual flame generator (e.g., a plurality of light sources, a plurality of lenses corresponding to the plurality of light sources, and a light source and a lens holder, etc.) in fig. 4a and 5a, and thus redundant description is omitted.

Referring to fig. 6, in the cooking information display 149, the reflector 145c is inclined at a predetermined angle α (e.g., 45 degrees) with respect to a vertical direction of the bottom surface 110b of the main body 110. For example, the predetermined angle α may be greater than 1 degree and less than 55 degrees with respect to a vertical direction of the bottom surface 110b of the body 110. For example, the predetermined angle α may be greater than 5 degrees and less than 48 degrees with respect to a vertical direction of the bottom surface 110b of the body 110. Further, the predetermined angle α may be changed by at least one of a manufacturer, a material of the top plate 120, and a distance between the work coils 130.
