The grill heater 100 may heat the inside of the cooking chamber 30 from the top. An upper portion of the food disposed inside the cooking chamber 30 may be heated by the grill heater 100, and the food may be entirely heated by a circulation module 35 to be described later.
The grill heater 100 may be an electric heater including an electric resistor. However, the type of grill heater 100 is not limited thereto, and may vary.
The grill heater 100 may include a plurality of straight sections 110, and a plurality of curved sections 120 connecting adjacent straight sections 110 among the plurality of straight sections 110. The grill heater 100 may be a component in which the plurality of straight sections 110 are connected to one another by the curved sections 120. As the grill heater 100 is installed as one component, costs may be lowered, and a surrounding structure for installing the grill heater 100 may be simplified, compared to a plurality of grill heaters 100 separated from each other.
The grill heater 100 may have a diameter of 5 mm or greater. For example, the grill heater 100 may have a diameter of 6 mm or greater. For example, the grill heater 100 may have a diameter of 6 mm to 8 mm.
As the inside of the cooking chamber 30 is heated by the grill heater 100, a temperature of the cooking chamber 30 may rise to a predetermined temperature. For example, the temperature of the cooking chamber 30 may be 250° C. or higher. When the cooking device 1 has a cleaning mode for cleaning the inside of the cooking chamber 30, the temperature of the cooking chamber 30 may further rise. For example, a maximum temperature of the cooking chamber 30 may be 400° C. or higher. For example, the maximum temperature of the cooking chamber 30 may be 400° C. to 600° C.
The main body 20 may include an electrical chamber 40 provided above the cooking chamber 30 to be separated from the cooking chamber 30. For example, the electrical chamber 40 may be provided between the inner case 31 and the outer case 21. Electrical parts (not shown) that control operations of various components may be disposed in the electrical chamber 40.
An insulating material (not shown) may be disposed between the cooking chamber 30 and the electrical chamber 40. Accordingly, leakage of heat inside the cooking chamber 30 to the outside of the cooking device 1 may be reduced, and transfer of heat from the cooking chamber 30 to the electrical chamber 40 may be reduced.
At least one circulation module 35 may be disposed at a rear side of the cooking chamber 30 to circulate air in the cooking chamber 30 so that food is evenly heated. For example, a plurality of circulation modules 35, for example, two circulation modules 35, may be arranged vertically on the rear side of the cooking chamber 30. Each of the circulation modules 35 may include a circulation fan (not shown) generating air flow, and a fan cover disposed in front of the circulation fan.
Referring to
The camera module 50 may be disposed at a center area of the upper portion of the cooking chamber 30. For example, the camera module 50 may be disposed at a center area of the upper portion of the cooking chamber 30 in a front-back direction. For example, the camera module 50 may be disposed close to the door 10 at the center area. For example, the camera module 50 may be disposed along a center line of the upper portion of the cooking chamber 30, and nearer to the door 10 than to a back of the cooking chamber 30. The center area in the front-back direction may be a central point located in the middle of the cooking chamber 30 in the front-back direction and a partial area including the center point. Accordingly, the camera module 50 may photograph the food from above the food without distortion. The photography of the food from the top may improve discrimination of the food. For example, the camera module 50 may be disposed between the central point and the door 10 at the center area.
The camera module 50 may be configured to photograph the inside of the cooking chamber 30. The camera module 50 includes a camera 51 that obtains photographing data of the inside of the cooking chamber 30. The photographing data may be at least one of an image or a moving picture.
The cooking device 1 may implement a time-lapse function of identifying food in the cooking chamber 30, monitoring the state of the food, and time-sequentially photographing and reproducing images of the food, based on the photographing data obtained by the camera 51.
At least a portion of the camera module 50 is disposed in the electrical chamber 40 and is disposed to face the cooking chamber 30. For example, the camera 51 of the camera module 50 may be disposed in the electrical chamber 40. Because the camera 51 disposed in the electrical chamber 40 is included to photograph the inside of the cooking chamber 30, an insulating material may not be disposed between the camera 51 and the cooking chamber 30. When the heat of the cooking chamber 30 is transferred to the camera 51, the camera 51 may be damaged, or performance thereof may be deteriorated. When the heat of the cooking chamber 30 is transferred to the electrical chamber 40, components within the electrical chamber 40 may be damaged, or errors may be generated.
Referring to
For example, the transparent heat blocking structure 52 may include a plurality of glasses. The plurality of glasses may include a first glass 521 disposed between the camera 51 and the cooking chamber 30, a second glass 522 disposed between the first glass 521 and the camera 51, and a third glass 523 disposed between the second glass 522 and the camera 51.
The transparent heat blocking structure 52 may be supported by a gap maintaining member 524. The gap maintaining member 524 may support the plurality of glasses and maintain a gap between the plurality of glasses. The gap maintaining member 524 may support the first glass 521, the second glass 522, and the third glass 523, and may maintain a gap between the first glass 521 and the second glass 522 and the second glass 522 and a gap between the second glass 522 and the third glass 523.
The first glass 521 may be provided in the inner case 31 such that a lower surface of the first glass 521 is exposed to the cooking chamber 30. When the inside of the cooking chamber 30 is heated, the lower surface of the first glass 521 may have a temperature corresponding to an internal temperature of the cooking chamber 30. For example, when the internal temperature of the cooking chamber 30 is heated to 450° C., the lower surface of the first glass 521 may rise to 450° C.
Even when the heat of the cooking chamber 30 is transferred to the lower surface of the first glass 521, the amount of heat transferred to the camera 51 may be reduced by the first glass 521, the second glass 522, the third glass 523, and air layers between the first, second, and third glasses 521, 522, and 523. The transparent heat blocking structure 52 may prevent the camera 51 from being overheated due to the heat of the cooking chamber 30. For example, the temperature of the camera 51 may be maintained at 20% or less of the temperature of the cooking chamber 30 so that the camera 51 does not overheat. For example, the temperature of the camera 51 may be maintained at a predetermined temperature, for example, 100° C. or less. For example, when the temperature of the cooking chamber 30 is 450° C., the temperature of the camera 51 disposed in the electrical chamber 40 may be 77.5° C.
A thickness of the transparent heat blocking structure 52 may be reduced through a triple glass structure, and, accordingly, the camera module 50 may photograph a determined photographing area 501. For example, a sum of the gaps between the glasses of the transparent heat blocking structure 52 may be 10 mm or less due to a triple glass structure. For example, a sum of the gap between the first glass 521 and the second glass 522 and the gap between the second glass 522 and the third glass 523 may be 10 mm or less. Accordingly, the camera module 50 may entirely photograph an area corresponding to at least a middle height of the cooking chamber 30.
The camera module 50 may photograph the inside of the cooking chamber 30 through the plurality of glasses of the transparent heat blocking structure 52. The photographing area 501 of the camera module 50 may be an area photographed by the camera 51 through the plurality of glasses. For example, the photographing area 501 of the camera module 50 may cover a plane size of the cooking chamber 30 at the middle height.
Referring back to
The inside of the cooking chamber 30 may have a predetermined brightness due to the lighting module 60. For example, an average illuminance at the middle height of the cooking chamber 30 may be 300 lux or more by the lighting module 60. For example, the average illuminance inside of the cooking chamber 30 by the lighting module 60 may be 400 lux or more based on a tray 32 at a third height among six-tiered trays 32.
Referring to
For example, the pair of lighting modules 60 may be disposed on both sides of the camera module 50 in a horizontal direction Y. However, the arrangement of the pair of lighting modules 60 is not limited thereto, and the pair of lighting modules 60 may be arranged in various ways as long as they are symmetrically disposed on both sides with the camera module 50 interposed therebetween. For example, as shown in
As the pair of lighting modules 60 are disposed on both sides with the camera module 50 interposed therebetween, light may be directly radiated to most areas of the cooking chamber 30, and a difference in illuminance inside the cooking chamber 30 may be reduced. For example, a light irradiation area 601 directly irradiated with light by each of the lighting modules 60 may be secured a predetermined size or more within the cooking chamber 30. For example, the light irradiation area 601 of each of the lighting modules 60 may cover at least half the plane size of the cooking chamber 30 at the middle height.
Referring to
Each of the lighting modules 60 may include a light guide plate 62 for reflecting the light generated by the light source 61 toward the cooking chamber 30, and a protective glass 63 disposed between the light source 61 and the cooking chamber 30. The light guide plate 62 may be disposed to surround the light source 61. The protective glass 63 may transmit light and block the heat of the cooking chamber 30. The protective glass 63 may perform a function of spreading the light while transmitting the light generated by the light source 61 and the light reflected by the light guide plate 62.
A radiation angle of light emitted by the lighting module 60 may be 80° to 90° with respect to the light source 61. For example, the radiation angle of the light emitted by the lighting module 60 may be 80° to 90° with respect to the light source 61 in the horizontal direction Y.
Referring back to
As such, the cooking device 1 in which the camera module 50 and the lighting module 60 are disposed along with the grill heater 100 above the cooking chamber 30 may be large in size. For example, one side of the cooking device 1 may be 500 mm or greater. One side of the cooking device 1 may be 600 mm to 1000 mm. For example, a size of the cooking chamber 30 may be large. For example, a capacity of the cooking chamber 30 of the cooking device 1 may be equal to or greater than a predetermined size. For example, the capacity of the cooking chamber 30 may be 80 liter or more. For example, the capacity of the cooking chamber 30 may be 100 liter or more. For example, the capacity of the cooking chamber 30 may be 80 liter to 300 liter. For example, the capacity of the cooking chamber 30 may be 100 liter to 250 liter.
As such, when the size of the cooking device 1 or the cooking chamber 30 is large, a structure of the grill heater 100 for heating the inside of the cooking chamber 30 may be changed. For example, a shape of the grill heater 100 may be changed.
Referring to
For example, an average of the gaps between the plurality of straight sections 110 of the grill heater 100 may be reduced. In other words, an average gap between the straight sections 110 of the grill heater 100 may be reduced.
For example, the plurality of straight sections 110 may include first straight sections 111 spaced apart from each other by a first gap G1, and second straight sections 112 disposed adjacent to the camera module 50 or the lighting module 60 and arranged by second gaps G21, G22, and G23 different from the first gap G1. The first gap G1 between the plurality of straight sections 110 in the grill heater 100 according to an embodiment of the disclosure may be small. The first gap G1 between the plurality of first straight sections 111 may be a gap between most, for example, half or more, of the straight sections 110 in the grill heater 100 according to an embodiment of the disclosure.
For example, the first gap G1 between the first straight sections 111 of the grill heater 100 may be less than a length of one side of the camera module 50. In other words, the length of one side of the camera module 50 may be greater than the first gap G1 of the grill heater 100. For example, the first gap G1 of the grill heater 100 may be less than a length of a longer side d1 of the camera module 50. The first gap G1 of the grill heater 100 may be less than a length of a shorter side of the camera module 50.
For example, the first gap G1 of the grill heater 100 may be less than a length of one side of the lighting module 60. In other words, the length of one side of the lighting module 60 may be greater than the first gap G1 of the grill heater 100. For example, the first gap G1 of the grill heater 100 may be less than a length of a longer side of the lighting module 60. For example, the first gap G1 of the grill heater 100 may be less than a length of a shorter side d2 of the lighting module 60. For example, the first gap G1 of the grill heater 100 may be 50 mm or less. For example, the first gap G1 of the grill heater 100 may be 45 mm or less.
When the first interval G1 of the grill heater 100 is small as described above, a portion of the grill heater 100 may be disposed close to the camera module 50 and the lighting module 60 disposed above the grill heater 100.
Considering this point, in the cooking device 1 according to an embodiment of the disclosure, the shape of the grill heater 100 may be designed such that the grill heater 100 does not cover the photographing area 501 of the camera module 50 or the light irradiation area 601 of the lighting module 60. In other words, the shape of the grill heater 100 may be designed such that the grill heater 100 does not interfere with the photographing area 501 of the camera module 50 or the light irradiation area 601 of the lighting module 60.
For example, the grill heater 100 may be configured such that light may be radiated into the cooking chamber 30 through a gap of the grill heater 100 by a pair of lighting modules 60 and the inside of the cooking chamber 30 through a gap of the grill heater 100 may be photographed by the camera module 50.
Referring to
The detour sections 130 may include a first detour section 131 bypassing the photographing area 501 of the camera module 50 and a second detour section 132 bypassing the light irradiation area 601 of the lighting module 60. The second bypass section 132 may bypass the light irradiation area 601 of the first lighting module or bypass the light irradiation area 601 of the second lighting module.
The first detour section 131 may have a shape that does not overlap the camera module 50 in a vertical direction, and a second bypass section 132 may have a shape that does not overlap the protective glass 63 of the lighting module 60.
For example, the first detour section 131 may extend from a rear side of the camera module 50 to a front side thereof by bypassing a left or right side of the camera module 50. For example, the first detour section 131 may extend from a rear side of the first glass 521 to a front side thereof by bypassing the left or right side of the camera module 50. For example, the second detour section 132 may change a direction without extending from a rear side of the lighting module 60 to a front side thereof, or may change a direction without extending from the front side of the lighting module 60 to the rear side thereof. However, the shape of the detour section 130 is exemplary, and may be variously modified within a range of bypassing the camera module 50 and the lighting module 60.
As the grill heater 100 includes the detour sections 130, a gap between the second straight sections 112 adjacent to the camera module 50 or the lighting module 60 in the straight section 110 may be increased or decreased. Being adjacent to the camera module 50 or the lighting module 60 refers to being closest to the camera module 50 or the lighting module 60 in a direction perpendicular to the extension direction of the straight section 110, for example, in the horizontal direction Y. The gaps between the second straight sections 112 of the grill heater 100 may include the second gaps G21, G22, and G23 different from the first gap G1. For example, the second gap G21 between a second straight section 1121 bypassing the left side of the photographing area 501 of the camera module 50 and a second straight section 1121 bypassing the right side of the photographing area 501 of the camera module 50 may be greater than the first gap G1 of the grill heater 100. For example, the second gap G22 between second straight sections 1122 and 1123 adjacent to the light irradiation area 601 of the lighting module 60 in the horizontal direction Y may be greater than the first gap G1 of the grill heater 100. For example, the second gap G23 between the second straight sections 1121 and 1122 arranged between the camera module 50 and the lighting module 60 may be less than the first gap G1 of the grill heater 100. In other words, the second gap G23 between the second straight sections 1121 adjacent to to the camera module 50 and the second straight sections 1122 adjacent to to the lighting module 60 may be less than the first interval G1 of the grill heater 100. For example, the second gap G23 between the second straight sections 1121 and 1122 arranged between to the camera module 50 and the lighting module 60 may be less than a gap G0 between the camera module 50 and the lighting module 60.
However, the shape of the grill heater 100 is exemplary and is not necessarily limited thereto, and may be variously modified within a range including the detour sections 130 bypassing the camera module 50 and the lighting module 60 so as not to overlap the camera module 50 and the lighting module 60 in the vertical direction Z.
When the grill heater 100 includes no detour sections 130 and a portion of the grill heater 100 covers the photographing area 501 of the camera module 50 or the light irradiation area 601 of the lighting module 60, a recognition rate of the cooking device 1 with respect to the food may decrease. For example, when the portion of the grill heater 100 covers the photographing area 501, a portion of the food may be covered, and accordingly, the food recognition rate may decrease. For example, when the portion of the grill heater 100 covers the light irradiation area 601, a shadow caused by the grill heater 100 is formed on the food, and accordingly, the food recognition rate may decrease.
In contrast, as the grill heater 100 according to an embodiment of the disclosure has a structure that does not cover the photographing area 501 and the light irradiation area 601, the food recognition rate of the cooking device 1 may be improved.
Referring to
For example, the camera module 50 may cover the plane size of the cooking chamber 30 at the middle height. The second gap G21 of the grill heater 100 may be designed so that the grill heater 100 does not interfere with the photographing area 501 of the camera module 50.
For example, the second gap G21 between the second straight sections 112 adjacent to the camera module 50 in the grill heater 100 may be determined in consideration of the vertical distance between the camera module 50 and the grill heater 100, the width of the cooking chamber 30, and a height of the cooking chamber 30. The height of the cooking chamber 30 may correspond to the distance between the camera module 50 and a bottom surface of the cooking chamber 30.
For example, given that a width, in the horizontal direction Y, of the grill heater 100 adjacent to the camera module 50 is G21, the vertical distance between the camera module 50 and the grill heater 100 is d, and a width of the cooking chamber 30 in the horizontal direction Y is w, and the distance between the camera module 50 and the bottom surface of the cooking chamber 30 is h, the second gap G21 of the grill heater 100 may be 2*d/h of w (G21 ≤2*d/h*w).
According to the above-described embodiment of the disclosure, a shape in which a length of the lighting module 60 in the front-back direction X corresponds to a length of the camera module 50 in the front-back direction X. However, the shape of the lighting module 60 is limited thereto. For example, as shown in
The shape of the grill heater 100 may vary within a range that does not interfere with the lighting module 60 and the camera module 50. For example, as shown in
