Description

[Technical field]

[0001] The present invention relates to a cooking appliance equipped with a camera that photographs the inside of a cooking chamber. [Background technology]

[0002] Some cooking chambers built into heating cookers such as induction cooking heaters and gas stoves can automatically cook a variety of dishes by simultaneously or alternately heating both the top and bottom sides of ingredients (food) such as bread or fish with heat sources (such as sheath heaters or gas burners) placed above and below the food. In this type of cooking chamber, in order to achieve automatic cooking, the heat is appropriately controlled according to the menu based on the detection value of a temperature sensor such as a thermistor installed inside the cooking chamber.

[0003] The built-in cooking chamber of a cooking device generally has an opening on the front side of the cooking device, and food is put in and taken out by opening and closing a door that covers the opening. Many doors of this type have a glass plate on the front side for heat resistance and design reasons, and when this configuration is adopted, the glass plate can be used as a viewing window to check the status of the food inside the cooking chamber. However, since the height of the cooking chamber from the floor when it is installed in a system kitchen is about 1 meter, many users have to bend forward to check the status of the food through the glass plate, which is a significant physical burden.

[0004] Therefore, instead of using the glass panel as a window, many users would open the kitchen door, pull out the food, and check the status of the food while standing upright. However, when checking the status of the food in this way, problems occur in that it takes longer to finish cooking and the energy consumption required to finish cooking increases because heat from inside the kitchen escapes while the door is open.

[0005] One method of solving these problems would be to show footage of the inside of the kitchen taken by a camera on a display installed in a highly visible position and allow the user to check the status of the food via the display, thereby avoiding the physical burden on the user and the various problems associated with opening the door.

[0006] Here, the cooking device of Patent Document 1 is known as a conventional cooking device that photographs the state of food in a cooking chamber with a camera installed on the wall of the cooking chamber. For example, the abstract of the document states that, in consideration of the deterioration of the photographing quality due to the steam generated from the food, the problem is to "photograph the food to a certain degree clearly even during cooking, and to prevent poor photographing of the food as much as possible." As a solution, it states that "the configuration includes a heating means 38 for heating the food 12, a heating chamber 13 having an opening 22 with a window member 25, a camera 24 that looks into the heating chamber 13 through the window member 25, and a windbreak wall 28 between the camera 24 and the window member 25, so that the window member 25 is not cooled excessively even when the camera 24, which is sensitive to heat, is cooled, and condensation on the window member 25 due to the steam generated during cooking is suppressed, and the clearest possible image of the food can be obtained."

[0007] Furthermore, paragraph 0042 of the same document states that "in the configuration of the present invention shown in FIG. 2, while the circuit board of camera 24 is cooled to below 50° C. with cooling air, windbreak wall 28 prevents the cooling air from hitting window member 25, so that window member 25 is not cooled excessively, and condensation and the adhesion of water droplets are suppressed."

[0008] In this way, Patent Document 1 discloses a technology in which a windbreak wall is provided between the window member and the camera looking into the cooking chamber through the window member, so that even if the heat-sensitive camera is cooled, the window member will not be cooled excessively, thereby suppressing condensation on the window member due to water vapor generated during cooking, and enabling the acquisition of the clearest possible images of food. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] JP 2020-165572 A Summary of the Invention [Problem to be solved by the invention]

[0010] However, when the windbreak wall is provided in the position shown in Figure 2 of Patent Document 1, in order to photograph the food in the heating chamber with a camera, it is necessary to install a lens facing toward the window member so that it protrudes from an opening provided in the windbreak wall. In that case, there is a possibility that high-temperature water vapor that has entered the space on the heating chamber side from the windbreak wall will condense on the surface of the lens that is indirectly cooled by heat exchange with the circuit board that is directly cooled by cooling air.

[0011] That is, the configuration of Patent Document 1 is sufficient as a countermeasure against condensation on the window member, but is not sufficient as a countermeasure against condensation on the lens surface. Even if condensation on the window member is eliminated, if condensation occurs on the lens surface, the condensation will have a negative effect on the shooting quality, so the configuration of Patent Document 1 is not sufficient as a configuration for shooting clear images.

[0012] On the other hand, when cooking time is long or cooking temperature is high, there is a concern that a lens that is indirectly cooled via a circuit board (i.e., a lens that cannot be directly cooled by cooling air) may be overheated by radiant heat from the cooking chamber. Therefore, measures to prevent the lens from overheating are also necessary, and a structure that excludes direct cooling of the lens, as in Patent Document 1, is not desirable.

[0013] Therefore, the object of the present invention is to provide a heating cooker that can prevent condensation and overheating on the lens of a camera that photographs the inside of the cooking chamber through a viewing window provided in the wall of the cooking chamber, and can clearly photograph the state of food being cooked inside the cooking chamber. [Means for solving the problem]

[0014] In order to achieve the above-mentioned object, the present invention is characterized by a built-in type heating cooker which has a main body, an induction heating unit, and a grill unit and is incorporated into a system kitchen, wherein the induction heating unit comprises a top plate having a pot mounting portion on its upper surface for placing a metal pot thereon, a heating coil which is provided below the pot mounting portion and which induction heats the metal pot, a board which supplies high-frequency current to the heating coil, and a first blower which blows air from within the system kitchen to the board, wherein the grill unit comprises a cooking chamber, an imaging device which is provided on the outside side of the cooking chamber and which photographs food in the cooking chamber through a sight glass, and a second blower which blows air from within the system kitchen to the imaging device, wherein the first blower draws in air from within the system kitchen through an intake opening provided on the back of the main body far from the grill unit, and the second blower draws in air from within the system kitchen through an intake port provided on the side or bottom of the main body closer to the grill unit. Effect of the Invention

[0015] According to the present invention, the state of food being cooked inside the cooking chamber can be clearly photographed through an observation window provided in the wall of the cooking chamber by an imaging device provided outside the cooking chamber. [Brief description of the drawings]

[0017] An embodiment of the cooking device of the present invention will be described in detail with reference to the drawings as appropriate. Note that, in the following, a built-in type IH cooking heater equipped with a grill unit will be illustrated as an example of the cooking device, but the present invention can also be applied to a built-in type gas stove or the like as long as the cooking device is equipped with an imaging device (camera module) that captures images of the inside of the cooking chamber. EXAMPLES

[0018] First, the overall configuration of the cooking device Z according to the first embodiment of the present invention will be outlined, and then the detailed structure of the grill section 5 will be described.

[0019] <Overall configuration of cooking device> The cooking device Z of this embodiment is a cooking device equipped with an induction heating section that generates eddy currents in the bottom of a metal pot placed on the top surface, and heats the metal pot itself with Joule heat due to the eddy currents, and a grill section that heats food stored in the cooking chamber with radiant heat from a heater. Note that, as shown in Figure 1, etc., in the following, the front-back, up-down, and left-right directions are defined based on the line of sight of the user facing the cooking device Z.

[0020] Fig. 1 is a perspective view of the cooking device Z. Fig. 2 is an exploded perspective view of Fig. 1. Fig. 3 is a front cross-sectional view of the cooking device Z taken along line AA shown in Fig. 1. Fig. 4 is a side cross-sectional view of the cooking device Z taken along line BB shown in Fig. 1.

[0021] As shown in each figure, the heating cooker Z is a cooker that includes a main body 1, a top plate 2, a heating coil 3, a substrate 7, and a substrate case 8 that houses the substrate 7, and further includes a cooking chamber 50 of the grill section 5 in which an imaging device 44 is disposed.

[0022] The main body 1 is a housing having an outer shell corresponding to the space (predetermined left-right width, front-back width, and height) in which the cooking device Z is installed, and is box-shaped (concave) with an open top. Inside the main body 1, a grill section 5 is disposed on the left side, and a circuit board case 8 is disposed on the right side. In addition, a heating coil 3, a display section P1, etc. are disposed above the grill section 5 and the circuit board case 8, and further, a top plate 2 is disposed so as to cover the top opening of the main body 1.

[0023] The grill section 5 on the left front side of the main body 1 is provided with an opening (not shown) that slides back and forth to place food F therein, and a door 6 is disposed to cover the opening. Also, on the right front side of the main body 1, a front panel 11 is disposed so as to be aligned so as to be substantially flat on the broad surface in front of the door 6, and a power switch 12 for turning the main power on and off is disposed. The front panel 11 may be shaped like a kangaroo pocket and used as an operating section for setting the heat settings of the grill section 5. The top plate 2 is comprised of a plate of glass (not shown) on which a cooking pot is placed, and a frame section (not shown) that holds the four sides of the plate of glass, and is disposed on top of the main body 1.

[0024] The board case 8 is a case that houses electrical components such as the board 7 inside. A fan device 9 (first air blower) for cooling the induction heating section is provided on the rear side of the board case 8, and is configured to draw in relatively low-temperature outside air from an intake opening H1 on the rear side of the main body 1, far from the grill section 5, and supply cooling air to the multiple boards 7 inside the board case 8 and the heating coil 3 arranged downstream thereof. Here, the electronic components on the board 7 are integrated circuits, inverter circuits, capacitors, resistors, etc. that are used to supply high-frequency current to the heating coil 3 and drive the fan device 9.

[0025] Top plate 2 has a three-port pot mounting section 21 corresponding to the installation positions of three heating coils 3, an operation section 23 for setting the heating level of a metal pot placed on pot mounting section 21, a display section 22 that mainly displays images of the inside of the cooking chamber captured by imaging device 44, and an exhaust opening H2. Note that exhaust opening H2 is the outlet of an air passage that starts from exhaust duct 59 of grill section 5, which will be described later, and intake opening H1, and is located at the rear (right or left side) of top plate 2.

[0026] <Configuration of grill section 5> As shown in each figure, the grill section 5 of this embodiment is equipped with a box-shaped cooking chamber 50 with an opening at the front for putting food in and taking it out. This cooking chamber 50 is constructed by assembling a plurality of members, each of which is formed into a predetermined shape by pressing aluminum alloy plates, with screws or the like.

[0027] In this cooking chamber 50, food is cooked in a deep-dish-shaped cooking pan 58 placed on a stand 54. The cooking pan 58 is a deep dish made of a material such as aluminum and formed in a rectangular shape when viewed from above, and the surface is coated with a fluorine coating agent or the like.

[0028] Heaters 51, upper heater 51a and lower heater 51b, are installed inside cooking chamber 50 to sandwich cooking pan 58, and by controlling the on / off of both heaters, it is possible to heat the top and bottom surfaces of food in cooking pan 58 simultaneously or alternately. Heater 51 is a heat source that utilizes radiant heat such as a sheath heater or electric heater.

[0029] In the grill section 5, a pair of slide rails 56 are provided on the left and right lower sides of the cooking chamber 50, allowing the door 6 for closing the front opening of the cooking chamber 50 to slide back and forth. By providing a rubber packing (not shown) on the outer periphery of the door 6 on the cooking chamber 50 side, the airtightness of the front opening of the cooking chamber 50 can be further improved. A stand 54 for placing a cooking pan 58 slides back and forth in conjunction with the door 6 using the slide rails 56. The door 6 and stand 54 are detachable, and if they become dirty they can be removed from the grill section 5 and washed.

[0030] An exhaust duct 59 is provided at the upper back side of the cooking chamber 50 to exhaust oily smoke, steam, etc. from within the cooking chamber 50, and is configured to exhaust from an exhaust opening H2 provided at the rear of the top plate 2 (see Figure 4).

[0031] As shown in Fig. 3, an imaging device 44 such as a camera is provided on the outside of the left side wall of the cooking chamber 50, and the imaging device 44 can capture an image of food F being cooked in a cooking pan 58 through a viewing window 41 provided in the wall of the cooking chamber 50. The imaging device 44 is installed in a storage case 42 that forms an air passage, and the storage case 42 is positioned so that the viewing window 41 is disposed opposite the imaging device 44, forming an air passage that communicates with a blower fan 40 (second blower) provided above the cooking chamber 50. The better the blower fan 40's blowing characteristics, the larger its external shape will be. Therefore, it is easier to select a fan with good blowing performance when the fan is disposed in the space above the cooking chamber 50 where the heating coil 3 is disposed, rather than in the narrow space between the cooking chamber 50 and the outer casing of the main body 1.

[0032] The blower fan 40 is configured as a blower type, for example a centrifugal fan or a multi-blade fan, with its intake side facing the intake port 10 provided on the side of the outer shell of the main body 1 and its discharge side facing the storage case 42, and efficiently guides the air sucked in from the side intake port 10 downward and supplies hot air to the imaging device 44 inside the storage case 42. Note that when the cooking appliance Z is installed in the kitchen, the intake port 10 will be positioned on the top plate 2 side, and is positioned so that it can easily suck in relatively high-temperature air (for example, around 60°C) heated by heat leakage from the cooking chamber 50, even within the kitchen.

[0033] In the first embodiment, as shown in Fig. 4, lighting devices 43 such as LEDs are arranged on the same wall surface of the kitchen 50 as the imaging device 44. The lighting devices 43 are installed to capture clear images from the imaging device 44. Therefore, the installation positions, number of lighting devices 43, and light intensity in the kitchen 50 are appropriately determined depending on the shape of the kitchen 50 and the position of the imaging device 44. The lighting devices 43 may be arranged in the storage case 42 together with the imaging device 44 depending on the need for cooling.

[0034] <Configuration incorporated into system kitchen> FIG. 5 is a perspective view of the cooking device Z installed in a system kitchen SK, and FIG. 6 is a schematic diagram of a cross section of the cooking device of FIG. 5 taken along line CC shown in FIG. 1 as viewed from above.

[0035] In a typical system kitchen SK, standard dimensions are specified so that a built-in type IH cooking heater can be installed. For example, when the storage section is placed below the cooking appliance Z, it is positioned so that the front is approximately flat, and the outer casing of the main body 1 is designed so that no large gaps are created around the door 6 or front panel 11 on the front side of the cooking appliance Z.

[0036] In a typical system kitchen SK, the height from the floor to the top plate 2 is about 80 cm, and the height of the center of the door 6 of the grill section 5 is about 70 cm. Therefore, it goes without saying that it is more convenient for a user standing upright to be able to check the inside of the cooking chamber via the display unit 22 on the top plate 2, rather than a user bending over to check the inside of the cooking chamber through the door window.

[0037] 6, when the built-in type cooking device Z is installed in the system kitchen SK, a gap 100a is provided between the system kitchen SK and the main body 1 so that the two do not come into contact with each other. This gap 100a is configured to be unnoticeable when viewed from the front by the door 6, the front panel 11, or a separately provided fitting part (not shown).

[0038] In this embodiment, the gap 100a constitutes a part of the air passage for blowing hot air to the imaging device 44, and the air in the gap 100a is sucked in by the blower fan 40 through the air intake 10. The air in the gap 100a, which forms the air passage upstream of the imaging device 44, is heated by the exhaust heat from the cooking chamber 50 when the grill unit 5 is in use. Therefore, the air sucked in by the blower fan 40 becomes hot air of about 60°C mixed with the outside air in front of the system kitchen SK, and the outer shell surface of the main body 1 in contact with the gap 100a constitutes a heat exchanger of the air passage.

[0039] Fig. 7 is a schematic diagram of a side cross section of the grill part in Fig. 5. Fig. 8 is a schematic diagram of a front cross section of the grill part in Fig. 5. The cooking device Z incorporated in the system kitchen SK has a flange on the outer periphery of the top plate 2, which is wider than the outer shell of the main body 1, and the top plate 2 supports the main body 1. Therefore, the main body 1 has gaps 100a in the left-right, downward, and rearward directions relative to the system kitchen SK. Therefore, the outer shell surface having a wide area of ​​the main body 1 forms a heat exchange part that exchanges heat with the outside air, efficiently raising the temperature of the outside air, which is then sucked in by the blower fan 40.

[0040] As shown in Figure 8, the imaging device 44 of this embodiment is a camera module (built-in camera) consisting of a substrate portion 44a and a lens portion 44b, and is positioned so that food F in the cooking pan 58 can be observed through the viewing window 41 from diagonally above the cooking chamber 50.

[0041] The storage case 42 is arranged such that the downstream opening 42a is narrowed toward the sight window 41 side with respect to the upstream air passage, and the air supplied from the blower fan 40 flows along the vicinity of the sight window 41. The air leaving the opening 42a passes through the main body 1 and is exhausted from the exhaust opening H2 on the top plate 2.

[0042] <Grilling operation> Next, the cooking operation in which an image captured inside the cooking chamber is displayed on the display unit 22 on the top plate 2 when the grill is actually in use will be specifically described with reference to Figures 1 to 8. Here, the explanation will be given taking as an example a case in which food F placed on a cooking pan 58 of a cooking chamber 50 is cooked in a cooking device Z installed in a system kitchen SK.

[0043] First, the user pulls the door 6 forward to open the front opening of the cooking chamber 50, places the cooking pan 58 with food placed on it into the cooking chamber 50, sets the cooking temperature and time on the operation unit 23 provided on the top plate 2, sets the frame rate of the cooking video to be filmed, and presses the start button (not shown) on the operation unit 23 to start grill cooking. Then, as cooking begins, the fan device 9 on the main body 1 is driven, and the upper heater 51a or the lower heater 51b is energized to heat the food. Also, the lighting device 43 in the cooking chamber 50 is turned on, the blower fan 40 is driven, and filming by the imaging device 44 begins.

[0044] When cooking begins, the temperature of cooking pan 58 in cooking chamber 50 rises and the food is heated, and the resulting heat raises the atmospheric temperature of cooking chamber 50, and the temperature also rises through observation window 41 provided in the wall of cooking chamber 50. As cooking progresses, heat leaks from gaps in the wall of cooking chamber 50 and door 6, and the air temperature in system kitchen SK gradually rises to around 60°C. In the configuration of the present invention, air from within the system kitchen SK is supplied into the storage case 42 via the blower fan 40 (second blower device). As a result, the temperatures of the sight glass 41 and the lens portion 44b of the imaging device 44 gradually rise as cooking progresses, thereby reducing the temperature difference between the inside of the cooking chamber and the sight glass 41, the temperature difference between both surfaces of the sight glass 41, and the temperature difference between the sight glass 41 and the lens portion 44b. This makes it possible to clearly photograph food F in the cooking chamber 50 while preventing condensation on the sight glass 41 and the lens portion 44b and while cooling the lens portion 44b to a certain extent with warm air of about 60°C to prevent overheating.

[0045] The state of the cooking chamber 50 during cooking is projected onto the display unit 22 on the top plate 2, allowing the user to grasp the situation inside the cooking chamber 50 even while performing other tasks in the kitchen. In the unlikely event that there is a difference between the initial heating setting on the operation unit 23 and the finished food, the user can easily achieve the desired doneness by adding more heating time, stopping the heating midway, and pulling the door 6 open to remove the cooking pan 58. With this configuration, cooking can be done with high thermal efficiency since there is no need to repeatedly check the doneness during cooking by opening the door (while allowing heat to escape to the outside). Also, since there is no need to repeatedly check through the door window (while bending over), cooking can be done with less strain on the body due to posture. EXAMPLES

[0046] Next, a cooking device Z according to a second embodiment will be described with reference to Fig. 9. Note that a duplicated description of points common to the first embodiment will be omitted.

[0047] FIG. 9 is a schematic diagram of a side cross section of the grill unit 5 of this embodiment, in which the imaging device 44 is provided in a cooking chamber 50 in which food F is cooked on a grill 58a above a tray 54a.

[0048] In FIG. 9, the blower fan 40 is disposed below the storage case 42, and both the blower fan 40 and the storage case 42 are provided on the side of the kitchen 50. The main air flow is the same as in FIG. 8, and the blower fan 40 sucks air from the gap 100a in the system kitchen SK and blows it to the imaging device 44 and the observation window 41 in the storage case 42. Similarly, the air path of the storage case 42 narrows the opening 42a downstream of the imaging device 44, and an exhaust duct 59 is provided downstream of it to exhaust air so as not to affect the cooling of the heating coil (see FIG. 3). This makes it easy to integrate the blower fan 40 and the storage case 42, reduces the number of parts, and makes assembly easier. In addition, the main flow is from bottom to top, making it easier to transport hot air rising by natural convection to the exhaust duct side, and allows for efficient air blowing. EXAMPLES

[0049] Next, a cooking device Z according to a third embodiment will be described with reference to Fig. 10. Note that a duplicated description of the points common to the first embodiment will be omitted.

[0050] FIG. 10 is a schematic diagram of a side cross section of the grill unit 5 of this embodiment, in which the imaging device 44 is provided in a cooking chamber 50 that uses a flat heater as a heater 51.

[0051] In FIG. 10, the blower fan 40 is disposed below the storage case 42, and both the blower fan 40 and the storage case 42 are provided on the side of the cooking chamber 50. The configuration in which the air in the gap 100a in the system kitchen SK is sucked in by the blower fan 40 and blown to the imaging device 44 and the observation window 41 in the storage case 42 is the same as in FIG. 8 and FIG. 9, and the air intake 10 is provided on the underside of the main body 1. In other words, the air passage on the upstream side of the storage case 42 is close to the lower heater 51b, and heat is exchanged with the sucked air, so that the temperature of the air blown to the storage case can be efficiently increased. The blower fan 40 is, for example, an axial fan in which the intake and blowing are in one direction. [Explanation of symbols]
