Abstract
Description
Technical Field
[0001] The invention relates to a heating cooking device. Background Art
[0002] Japanese Patent Application Laid-Open No. 2002-208468 discloses a conventional cooking device, which includes a housing, a top plate, an induction heating unit, a duct, and an air supply unit.
[0003] The housing is formed in a substantially rectangular box shape with an open top. The top plate is mounted on the upper portion of the housing. The induction heating unit can heat the food to be cooked by electromagnetic induction.
[0004] The duct is disposed within the housing. It has an inlet and an outlet. Furthermore, a through hole extending vertically through the duct is formed. The through hole houses the induction heating unit via the coil housing. The air supply unit is disposed within the housing. The air supply unit is capable of supplying cooling air from the exterior of the housing to the interior of the housing.
[0005] In this cooking device, cooling air supplied to the interior of the housing by the air supply unit flows from the inlet port into the interior of the duct. Thus, the cooling air within the duct cools the induction heating unit. In this cooking device, the cooling air flows vertically between the interior of the duct and the induction heating unit through the through-holes and the coil box, cooling the induction heating unit. The cooling air, which has cooled the induction heating unit, is then discharged from the interior of the duct via the outlet port.
[0006] In this manner, in this cooking device, the induction heating unit can be cooled by the cooling air flowing through the interior of the duct, and thus, the induction heating unit can be prevented from reaching an excessively high temperature during operation.
[0007] However, in the conventional cooking device, the cooling air flows vertically through the housing between the interior of the duct and the induction heating unit. Consequently, the cooling air flowing vertically through the induction heating unit easily generates wind noise, making it difficult to suppress noise during operation. Summary of the Invention
[0008] Therefore, a non-limiting object of the present invention is to provide a cooking device that has excellent durability and can operate quietly. This object is achieved according to the teachings of claim 1. Further developments of the present invention are described in the dependent claims.
[0009] The heating cooking device of the present invention comprises:
[0010] a housing having an opening at its upper portion;
[0011] a top plate mounted on an upper portion of the housing;
[0012] an induction heating unit capable of heating the food being cooked by electromagnetic induction;
[0013] a box body, which is disposed inside the shell and accommodates the induction heating unit; and
[0014] an air supply unit disposed inside the housing and capable of supplying cooling air from outside the housing to inside the housing,
[0015] The box body has: a bottom wall; and a peripheral wall connected to the outer edge of the bottom wall, surrounding the bottom wall and extending upward toward the top plate.
[0016] The top plate, the bottom wall, and the peripheral wall form a cooling chamber for cooling the induction heating unit using the cooling air.
[0017] The peripheral wall is formed with: an inlet for introducing the cooling air into the cooling chamber; and an outlet located downstream of the inlet in the flow direction of the cooling air and for outlet the cooling air from the cooling chamber.
[0018] The bottom wall has a placement portion for the induction heating unit to be placed thereon.
[0019] The placement portion includes an upper surface facing upward and in contact with the induction heating unit, and a lower surface located on the opposite side of the upper surface in the vertical direction of the housing and facing downward.
[0020] The placement portion prevents the cooling air from flowing between the upper surface and the lower surface in the vertical direction of the housing.
[0021] The cooking device of the present invention has a bottom wall with a placement portion on which the induction heating unit is placed. Furthermore, the induction heating unit is cooled by cooling air introduced into the cooling chamber from the inlet. More specifically, the cooling air is cooled by cooling air flowing between the top plate and the induction heating unit within the cooling chamber. This prevents the induction heating unit from reaching excessively high temperatures during operation.
[0022] Here, the placement portion prevents cooling air from flowing vertically between the upper and lower surfaces of the housing. This prevents, for example, cooling air within the cooling chamber from flowing from the upper surface of the placement portion toward the lower surface, toward the lower portion of the housing, and being directed out of the cooling chamber from the lower surface, or cooling air from outside the cooling chamber from flowing from the lower surface of the placement portion toward the upper portion, toward the upper portion of the housing, and being directed into the cooling chamber. As a result, this cooking device prevents cooling air from flowing vertically through the induction heating unit within the cooling chamber, thereby reducing wind noise generated by the cooling air passing through the induction heating unit in the vertical direction of the housing.
[0023] Therefore, the cooking device of the present invention has excellent durability and can exhibit high quietness during operation.
[0024] In another embodiment of the present invention, the bottom wall may include a main portion located outside the receiving portion and a connecting portion located between the receiving portion and the main portion. Alternatively, the receiving portion may be located above the main portion. Furthermore, the connecting portion preferably extends vertically along the housing, connecting the receiving portion and the main portion, and preventing cooling air within the cooling chamber from flowing toward the lower surface.
[0025] In this case, the induction heating unit can be appropriately brought close to the top plate while being placed on the placement portion. Furthermore, the connection portion prevents the cooling air within the cooling chamber from flowing toward the lower surface of the placement portion. Therefore, in this cooking device, wind noise is not generated by the cooling air within the cooling chamber flowing from the connection portion toward the lower surface of the placement portion. Furthermore, by preventing the cooling air within the cooling chamber from flowing toward the lower surface of the placement portion, the cooking device can increase the flow rate of the cooling air flowing between the top plate and the induction heating unit in the cooling chamber. Consequently, in this cooking device, the cooling air can be used to more appropriately cool the induction heating unit.
[0026] In another embodiment of the present invention, the connecting portion is preferably integrally formed with the mounting portion and the main body. In this case, the housing can be easily manufactured. Furthermore, this cooking device can suppress variations in the height of the mounting portion, thereby suppressing variations in the vertical distance between the top plate and the induction heating unit.
[0027] In another embodiment of the present invention, there may be multiple induction heating units. Furthermore, the bottom wall preferably has multiple mounting portions. In this case, variations in the heights of the mounting portions can be suppressed, thereby suppressing variations in the vertical spacing between the top plate and the induction heating units. Furthermore, variations in the relative distances between the mounting portions can be suppressed. This can suppress resonance and resonant vibrations between the induction heating units during operation, thereby achieving a high level of quietness during operation of the cooking device.
[0028] In another embodiment of the present invention, the space between the top plate and the upper end of the peripheral wall is preferably sealed with a sealing member. In this case, noise generated by cooling air leaking from the space between the top plate and the upper end of the peripheral wall can be prevented. Furthermore, since cooling air from the cooling chamber is less likely to leak from the space between the top plate and the upper end of the peripheral wall, the induction heating unit can be properly cooled using the cooling air from the cooling chamber.
[0029] In another embodiment of the present invention, the cooking device of the present invention preferably includes a gas heating unit that burns gas to heat the food being cooked. In this case, the gas heating unit can be used to heat not only food that cannot be heated by electromagnetic induction, but also food that is difficult to heat quickly by electromagnetic induction. This improves the convenience of the cooking device.
[0030] Other aspects and advantages of the present invention will become apparent from the following description and the embodiments disclosed in the drawings, the diagrams illustrated in the drawings, and the concept of the present invention disclosed in the specification and the drawings as a whole.

DETAILED DESCRIPTION
[0039] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0040] like Figure 1 and Figure 2 As shown, the cooking device 100 of the embodiment includes a housing 1, a top plate 3, a first heating coil 5, a second heating coil 7, a cabinet 9, a cooling fan 11, a heating grill 13, a stove burner 15, and a control unit 17. The first heating coil 5 and the second heating coil 7 are examples of the "induction heating unit" of the present invention. Furthermore, the heating grill 13 and the stove burner 15 are examples of the "gas heating unit" of the present invention. The cooking device 100 is installed in a residential kitchen (not shown).
[0041] In this embodiment, Figure 1 The arrows shown define the front-back direction and the up-down direction of the housing 1, and even the heating cooking device 100. In addition, in this embodiment, the left-right direction of the heating cooking device 100 is defined based on the user of the heating cooking device 100 (not shown) facing the heating cooking device 100 from the front, with the right side of the user being the right side of the heating cooking device 100 and the left side of the user being the left side of the heating cooking device 100. The above-mentioned front-back direction, up-down direction and left-right direction are orthogonal to each other. Moreover, in Figure 2 Later, with Figure 1 The front-back direction, the up-down direction, and the left-right direction of the cooking apparatus 100 are defined accordingly.
[0042] like Figure 1 and Figure 2As shown, the housing 1 has a first wall 1a, a second wall 1b, a third wall 1c, a fourth wall 1d, and a fifth wall 1e. The first wall 1a is located at the front end of the housing 1 and is formed into a rectangular plate extending in the left-right direction and the vertical direction. The second wall 1b is located at the rear end of the housing 1 and is formed into a rectangular plate extending in the left-right direction and the vertical direction. The first wall 1a and the second wall 1b are separated in the front-to-back direction and are parallel to each other in the left-to-right direction. Thus, the first wall 1a constitutes the front portion of the housing 1, and the second wall 1b constitutes the rear portion of the housing 1.
[0043] The third wall 1c is located between the first wall 1a and the second wall 1b, and is located at the right end of the shell 1. The third wall 1c is formed into a rectangular plate extending in the front-to-back direction and the up-down direction, with the front end connected to the right end of the first wall 1a and the rear end connected to the right end of the second wall 1b. The fourth wall 1d is located between the first wall 1a and the second wall 1b, and is located at the left end of the shell 1. The fourth wall 1d is formed into a rectangular plate extending in the front-to-back direction and the up-down direction, with the front end connected to the left end of the first wall 1a and the rear end connected to the left end of the second wall 1b. Thus, the third wall 1c and the fourth wall 1d are separated in the left-to-right direction and are parallel to each other in the front-to-back direction, respectively constituting the right side and the left side of the shell 1.
[0044] The fifth wall 1e is formed into a plate-like shape extending in the front-to-back and left-to-right directions, and is positioned between the first wall 1a, the second wall 1b, the third wall 1c, and the fourth wall 1d. The front end of the fifth wall 1e is connected to the lower portion of the first wall 1a, the rear end is connected to the lower portion of the second wall 1b, the right end is connected to the lower portion of the third wall 1c, and the left end is connected to the lower portion of the fourth wall 1d. Thus, the fifth wall 1e is surrounded by the first wall 1a, the second wall 1b, the third wall 1c, and the fourth wall 1d, and forms the bottom portion of the housing 1.
[0045] The housing 1 is formed into a substantially rectangular box-like shape with an upper opening by the first wall 1a, second wall 1b, third wall 1c, fourth wall 1d, and fifth wall 1e. Here, the housing 1 is formed into a rectangular shape in which the length in the left-right direction is longer than the length in the front-to-back direction. The lengths of the housing 1 in the front-to-back direction, the left-to-right direction, and the top-to-bottom direction can be appropriately designed.
[0046] like Figure 1As shown, in addition to the first operating portion 41a and the second operating portion 41b, an opening 10 is formed on the first wall 1a. The first operating portion 41a comprises a plurality of operating buttons 411 and a liquid crystal panel 412. The first operating portion 41a can be used to operate the first and second heating coils 5 and 7 as well as the heating grill 13. The second operating portion 41b comprises an operating dial and can be used to operate the stove burner 15. In addition to the various configurations of the first and second operating portions 41a and 41b described above, the positions of the first and second operating portions 41a and 41b on the first wall 1a can be appropriately designed. Alternatively, the first operating portion 41a can be positioned on the top plate 3. Furthermore, a single operating portion capable of operating the first and second heating coils 5 and 7, the heating grill 13, and the stove burner 15 can be positioned on the first wall 1a, or four operating portions corresponding to the first and second heating coils 5 and 7, the heating grill 13, and the stove burner 15, respectively, can be positioned on the first wall 1a. In addition, any one of the first and second heating coils 5 and 7 and the heating grill 13 can be operated by the operation dial, and the stove burner 15 can also be operated by the operation button.
[0047] The opening 10 is disposed between the first operating portion 41a and the second operating portion 41b. The opening 10 is opened in a rectangular shape on the first wall 1a. Figure 2 For ease of explanation, the first and second operating parts 41a and 41b are omitted from illustration.
[0048] A vent 21 is provided on the second wall 1b. The vent 21 comprises a plurality of vents 211 extending through the second wall 1b in the front-to-back direction. The vent 21 connects the interior and exterior of the housing 1. Alternatively, the vent 21 may be provided at the rear of the top plate 3 or elsewhere.
[0049] like Figure 1 As shown, the top plate 3 is formed into a rectangular plate shape. More specifically, the top plate 3 is formed into a rectangular plate shape in a manner corresponding to the shape of the housing 1, wherein the length in the left-right direction is longer than the length in the front-back direction. Figure 6 As shown, top plate 3 has a surface 301 facing upward and a back surface 302 located opposite surface 301 and facing downward. Top plate 3 is formed of inorganic glass colored in an opaque color such as black. Alternatively, top plate 3 may be formed of materials other than inorganic glass.
[0050] The top plate 3 is fixed to the upper portion of the housing 1 and covers the interior of the housing 1 from above. Thus, the surface 301 of the top plate 3 faces the top of the heating cooking device 100. On the other hand, the back surface 302 of the top plate 3 faces the interior of the housing 1. Figure 6 For ease of explanation, illustration of the heating grill 13 and the like is omitted.
[0051] In addition, if Figure 1 As shown, an exhaust port 3a is formed on the left rear portion of the top plate 3. Exhaust port 3a is formed in a rectangular shape, with its left-right length longer than its front-to-back length, and extends vertically through the top plate 3. Thus, when the top plate 3 is secured to the upper portion of the housing 1, exhaust port 3a connects the interior and exterior of the housing 1. In addition to the position of exhaust port 3a on the top plate 3, the shape of exhaust port 3a can also be appropriately designed. Alternatively, exhaust port 3a can be formed on the second wall 1b of the housing 1, for example.
[0052] Furthermore, an exhaust hood 30 is attached to the top plate 3. The exhaust hood 30 is formed in a rectangular shape corresponding to the exhaust port 3a and covers the exhaust port 3a from above. A plurality of punched holes 310 are formed in the exhaust hood 30.
[0053] Furthermore, a first guide mark 31 and a second guide mark 32 are provided on the top plate 3. The first guide mark 31 and the second guide mark 32 are each formed in an annular shape. The first guide mark 31 and the second guide mark 32 are located on the top plate 3 to the right of the stove burner 15 and in front of the exhaust port 3a. In addition, the first guide mark 31 and the second guide mark 32 are arranged in the front-to-back direction with a predetermined interval set in the front-to-back direction. Here, the second guide mark 32 is formed in an annular shape with a smaller diameter than the first guide mark 31 and is arranged in front of the first guide mark 31. In addition, the shapes of the first guide mark 31 and the second guide mark 32 are not limited to annular shapes, and can also be rectangular, cross-shaped, etc. In addition, the first guide mark 31 can also be smaller than the second guide mark 32.
[0054] Furthermore, a first cooking temperature sensor 33 and a second cooking temperature sensor 34 are provided on the top plate 3. The first cooking temperature sensor 33 is arranged inside the first guide mark 31, and the second cooking temperature sensor 34 is arranged inside the second guide mark 32.
[0055] The first cooking temperature sensor 33 can detect the temperature of food (not shown) placed inside the first guide mark 31 on the top plate 3. Similarly, the second cooking temperature sensor 34 can detect the temperature of food placed inside the second guide mark 32 on the top plate 3. Here, the first and second cooking temperature sensors 33 and 34 detect the temperature of food by measuring the temperature of a cooking container (not shown) such as a frying pan or pot containing the food. Furthermore, multiple first and second cooking temperature sensors 33 and 34 may be provided inside the first and second guide marks 31 and 32, respectively.
[0056] like Figure 2 and Figure 3As shown, the first heating coil 5 includes a first coil body 51 , eight first ferrite cores 52 , and a first shielding ring 53 . The second heating coil 7 includes a second coil body 71 , six second ferrite cores 72 , and a second shielding ring 73 .
[0057] Here, the second coil body 71, the second ferrite core 72, and the second shielding ring 73 have the same structure as the first coil body 51, the first ferrite core 52, and the first shielding ring 53, except that they are respectively smaller. Therefore, the following description focuses on the structure of the first coil body 51, the first ferrite core 52, and the first shielding ring 53, and the description of the structure of the second coil body 71, the second ferrite core 72, and the second shielding ring 73 is omitted as appropriate.
[0058] like Figure 3 As shown, the first coil body 51 is formed by winding a metal wire several times and is formed into a ring shape when viewed from above. In addition, the first heating coil 5 has an outer peripheral portion and an inner peripheral portion. The outer peripheral portion and the inner peripheral portion are separated by a predetermined interval in the radial direction of the first heating coil 5.
[0059] like Figure 3 and Figure 5 As shown, each first ferrite core 52 has the same shape and is formed into a rectangular column with a predetermined length. Each first ferrite core 52 is arranged below the first coil body 51 and is arranged at equal intervals in the circumferential direction of the first coil body 51. In addition, each first ferrite core 52 is in contact with the first coil body 51 when it is arranged below the first coil body 51. In addition, the number and shape of the first ferrite cores 52 can be appropriately designed according to the shape of the first coil body 51.
[0060] like Figure 3 As shown, the first shielding ring 53 is formed of a metal plate and is formed into a circular ring shape having a diameter larger than that of the first coil body 51 when viewed from above. The first shielding ring 53 is arranged outside the first coil body 51 and each first ferrite core 52, and surrounds the first coil body 51 and each first ferrite core 52 from the outside. Figure 5 As shown, the first shield ring 53 extends upward beyond the first coil body 51 .
[0061] Figures 2 to 5 The housing 9 shown is made of resin and has a bottom wall 91 and a peripheral wall 92 .
[0062] The bottom wall 91 is formed into a rectangular plate shape extending in the front-back direction and the left-right direction. More specifically, the bottom wall 91 is formed into a rectangular plate shape whose length in the front-back direction is longer than its length in the left-right direction.
[0063] The peripheral wall 92 is connected to the outer edge of the main body 91c of the bottom wall 91 and extends upward from the bottom wall 91, that is, within the interior of the housing 1 toward the top plate 3. Thus, the peripheral wall 92 forms a rectangular ring shape surrounding the bottom wall 91. Furthermore, the box body 9 is formed into a bottomed box shape with an open top by the bottom wall 91 and the peripheral wall 92. The main body 91c will be described later.
[0064] Furthermore, the peripheral wall 92 is formed with a first protrusion 92a and a second protrusion 92b. The first protrusion 92a is located at the front of the peripheral wall 92, in the center portion thereof in the left-right direction, and protrudes forward. An inlet 93 is formed in the first protrusion 92a. The inlet 93 penetrates the front portion of the peripheral wall 92, including the first protrusion 92a, in the front-to-back direction. The second protrusion 92b is located at the rear portion of the peripheral wall 92, in the center portion thereof in the left-to-right direction, and protrudes rearward. An outlet 94 is formed in the second protrusion 92b. The outlet 94 penetrates the rear portion of the peripheral wall 92, including the second protrusion 92b, in the front-to-back direction.
[0065] Furthermore, a closing member 95 is provided at the upper end of the peripheral wall 92. The closing member 95 is formed into a rectangular ring shape along the shape of the peripheral wall 92. Figures 3 to 6 As shown, a rectangular, annular box groove 920 is formed at the upper end of the peripheral wall 92. A sealing member 95 is received within this box groove 920 and is mounted on the upper end of the peripheral wall 92. The sealing member 95 is formed of a resin such as synthetic rubber and is elastically deformable. Alternatively, the sealing member 95 can be mounted directly on the upper end of the peripheral wall 92 without forming the box groove 920 in the peripheral wall 92.
[0066] like Figure 4 and Figure 5 As shown, the bottom wall 91 of the housing 9 includes a first receiving portion 91a, a second receiving portion 91b, a main body portion 91c, a first connecting portion 91d, and a second connecting portion 91e. The first receiving portion 91a and the second receiving portion 91b are examples of "receiving portions" of the present invention. Furthermore, the first connecting portion 91d and the second connecting portion 91e are examples of "connecting portions" of the present invention.
[0067] like Figure 4 As shown, the first receiving portion 91a and the second receiving portion 91b are arranged in a state of being spaced apart in the front-back direction and arranged in the left-right center of the bottom wall 91. At this time, the second receiving portion 91b is arranged in front of the first receiving portion 91a.
[0068] The first placement portion 91a is formed to have a diameter larger than Figure 2 and Figure 3The first shielding ring 53 of the first heating coil 5 shown in the figure is circular. Similarly, the second receiving portion 91b is formed to have a larger diameter than the second shielding ring 73 of the second heating coil 7 when viewed from above. Furthermore, the second receiving portion 91b is formed to have a smaller diameter than the first receiving portion 91a. As described above, the bottom wall 91 is formed in a plate shape, so the first receiving portion 91a and the second receiving portion 91b are each formed in a disc shape.
[0069] like Figure 5 As shown, the first receiving portion 91a and the second receiving portion 91b are each located above the main body 91c. Here, the first receiving portion 91a and the second receiving portion 91b are at the same height from the main body 91c. Alternatively, the first receiving portion 91a and the second receiving portion 91b may be at different heights from the main body 91c.
[0070] The first receiving portion 91a has an upper surface 901 and a lower surface 902. Meanwhile, the second receiving portion 91b has an upper surface 903 and a lower surface 904. Upper surfaces 901 and 903 face the top of the housing 9, that is, the top plate 3. Lower surfaces 902 and 904 are located on the opposite side of the housing 1 from upper surfaces 901 and 903 in the vertical direction. Lower surfaces 902 and 904 face the bottom of the housing 9, that is, the interior of the housing 1.
[0071] like Figure 4 As shown, eight first receiving recesses 911 and first annular recesses 912 are formed in the first receiving portion 91a. Each first receiving recess 911 is formed as a rectangular depression downward from the upper surface 901. Furthermore, each first receiving recess 911 is arranged at equal intervals around the circumference of the first receiving portion 91a. The first annular recess 912 is arranged outside each first receiving recess 911, at a location that forms the outer circumference of the first receiving portion 91a. The first annular recess 912 is formed as a circular depression downward from the upper surface 901.
[0072] Six second receiving recesses 921 and a second annular recess 922 are formed in the second receiving portion 91b. Each second receiving recess 921 is formed as a rectangular depression downward from the upper surface 903. Furthermore, the second receiving recesses 921 are arranged at equal intervals around the circumference of the second receiving portion 91b. The second annular recess 922 is arranged outside each second receiving recess 921, at a location that forms the outer circumferential end of the second receiving portion 91b. The second annular recess 922 is formed as a circular depression downward from the upper surface 903.
[0073] Here, in the first receiving portion 91a, each of the first receiving recesses 911 and the first annular recess 912 is merely recessed downward from the upper surface 901. That is, each of the first receiving recesses 911 and the first annular recess 912 does not vertically connect the upper surface 901 and the lower surface 902 of the first receiving portion 91a. Furthermore, the first receiving portion 91a does not have a hole or the like that extends vertically from the upper surface 901 to the lower surface 902.
[0074] Similarly, in the second receiving portion 91b, the second receiving recesses 921 and the second annular recess 922 are merely recessed downward from the upper surface 903. The second receiving recesses 921 and the second annular recess 922 do not vertically connect the upper surface 903 and the lower surface 904 of the second receiving portion 91b. Furthermore, the second receiving portion 91b does not have a hole or the like that passes vertically from the upper surface 903 to the lower surface 904.
[0075] The main body 91c is located outside the first and second mounting portions 91a, 91b. The main body 91c extends in a flat plate shape. In other words, the main body 91c does not have a hole or the like that passes through the main body 91c in the vertical direction.
[0076] like Figure 5 As shown, the first connecting portion 91d is located between the first receiving portion 91a and the main body portion 91c. The first connecting portion 91d is formed into a cylindrical shape extending in the vertical direction. Furthermore, the first connecting portion 91d is formed to have the same diameter as the first receiving portion 91a. The first connecting portion 91d is integrally formed with the main body portion 91c at its lower end and with the first receiving portion 91a at its upper end.
[0077] In addition, the first connecting portion 91d is formed integrally with the main body 91c and the first loading portion 91a, so that the first connecting portion 91d functions as a vertical wall that positions the first loading portion 91a above the main body 91c and surrounds the lower surface 902 of the first loading portion 91a from the outside.
[0078] The second connecting portion 91e is located between the second receiving portion 91b and the main body 91c. The second connecting portion 91e is formed into a cylindrical shape extending in the vertical direction. Furthermore, the second connecting portion 91e is formed to have the same diameter as the second receiving portion 91b. In other words, the second connecting portion 91e is formed into a cylindrical shape with a smaller diameter than the first connecting portion 91d. The second connecting portion 91e is integrally formed with the main body 91c at its lower end and with the second receiving portion 91b at its upper end.
[0079] In addition, the second connecting portion 91e is formed integrally with the main body 91c and the second loading portion 91b, so that the second connecting portion 91e functions as a vertical wall that positions the second loading portion 91b above the main body 91c and surrounds the lower surface 902 of the second loading portion 91b from the outside.
[0080] Here, the first connecting portion 91d and the second connecting portion 91e are formed into a flat cylindrical shape. Consequently, there are no radially penetrating holes or the like in the first connecting portion 91d and the second connecting portion 91e. Furthermore, the first receiving portion 91a, the second receiving portion 91b, and the main body 91c are integrally formed on the bottom wall 91 by the first connecting portion 91d and the second connecting portion 91e. Furthermore, the first connecting portion 91d and the second connecting portion 91e can be cylindrical in shape, with the diameter decreasing as they move upward, or they can be cylindrical in shape, with the diameter decreasing as they move downward.
[0081] like Figure 3 As shown, with respect to the housing 9, the first heating coil 5 is placed on the first receiving portion 91a, and the second heating coil 7 is placed on the second receiving portion 91b. At this time, with respect to the first heating coil 5, each first ferrite core 52 is respectively accommodated in each first receiving recess 911 of the first receiving portion 91a. In addition, the first shielding ring 53 is arranged in the first annular recess 912. Similarly, with respect to the second heating coil 7, each second ferrite core 72 is respectively accommodated in each second receiving recess 921 of the second receiving portion 91b. In addition, the second shielding ring 73 is arranged in the second annular recess 922.
[0082] like Figure 2 and Figure 3 As shown, a first mounting plate 201 and a second mounting plate 202 are mounted on the housing 9. The first mounting plate 201 and the second mounting plate 202 are formed of metal plates. The first mounting plate 201 and the second mounting plate 202 are symmetrical and are formed into a rectangular shape that is longer than the housing 9 in the front-to-back direction.
[0083] The first mounting plate 201 is disposed on the right side of the housing 9 in contact with the peripheral wall 92. Meanwhile, the second mounting plate 202 is disposed on the left side of the housing 9 in contact with the peripheral wall 92. The first mounting plate 201 and the second mounting plate 202 are fixed to the peripheral wall 92 using mounting screws (not shown).
[0084] like Figure 2 As shown, the box body 9 is arranged inside the housing 1 with the first heating coil 5 and the second heating coil 7 placed on the first placement portion 91a and the second placement portion 91b, respectively. That is, the box body 9, the first heating coil 5, the second heating coil 7, the first mounting plate 201, and the second mounting plate 202 are located below the top plate 3.
[0085] Furthermore, the first mounting plate 201 and the second mounting plate 202 are attached to the back surface 302 of the top plate 3 using a double-sided adhesive tape (not shown). Thus, the box body 9 is arranged inside the housing 1 in a state of being attached to the back surface 302 of the top plate 3 via the first mounting plate 201 and the second mounting plate 202 (see FIG. Figure 5 ).
[0086] Furthermore, the housing 9 is attached to the top plate 3 in this manner, and the top plate 3, bottom wall 91, and peripheral wall 92 form a cooling chamber 60 within the housing 9. In other words, the top plate 3, bottom wall 91, and peripheral wall 92 define the cooling chamber 60 within the housing 1. Furthermore, the inlet 93 and outlet 94 are each connected to the cooling chamber 60. Thus, the inlet 93 and outlet 94 connect the cooling chamber 60 to the outside of the cooling chamber 60, that is, connect the cooling chamber 60 to the interior of the housing 1.
[0087] Furthermore, the first heating coil 5 and the second heating coil 7 are arranged in the cooling chamber 60 in a state of being placed on the first placement portion 91a and the second placement portion 91b. In addition, as described above, the first placement portion 91a and the second placement portion 91b are located above the bottom wall 91 relative to the main body portion 91c. Therefore, the first heating coil 5 and the second heating coil 7 are formed in the cooling chamber 60 in a state closer to the top plate 3 than the main body portion 91c of the bottom wall 91 (see FIG. Figure 6 ).
[0088] Furthermore, the box 9 is attached to the back surface 302 of the top plate 3, so that the closing member 95 contacts the back surface 302 of the top plate 3 and elastically deforms in the box groove 920. Thus, the closing member 95 closes the space between the top plate 3 and the peripheral wall 92.
[0089] like Figure 2 As shown, the cooling fan 11 is provided inside the housing 1. More specifically, the cooling fan 11 is provided in a position further forward than the second wall 1b and further rearward than the box body 9.
[0090] The cooling fan 11 includes a fan case 11 a and a fan body 11 b . The fan case 11 a is attached to the fifth wall 1 e via a fixing base 18 so as to adjust its height relative to the housing 9 .
[0091] The fan housing 11a is formed with an air inlet 111 and an air outlet 112. The air inlet 111 is formed at the upper rear portion of the fan housing 11a. The air outlet 112 is formed at the front end of the fan housing 11a. Although not shown, a motor that rotates the fan body 11b is housed within the fan housing 11a. The fan body 11b is housed within the fan housing 11a, with a portion of the fan body protruding from the air inlet 111.
[0092] Regarding the cooling fan 11, the fan body 11b rotates inside the fan housing 11a, thereby circulating air from outside the housing 1 into the housing 1 through the vent 21. The fan body 11b then draws this air into the fan housing 11a through the air inlet 111. The cooling fan 11 then delivers the air drawn into the fan housing 11a as cooling air through the outlet 112 into the housing 1. The cooling fan 11 may also have other configurations.
[0093] The heating grill 13 has a heating box 13a, a grill door 13b and Figure 1 The grill tray 13c shown. Figure 2 As shown, the heating box 13a is formed into a substantially rectangular box shape extending in the front-back direction and the left-right direction. The front end of the heating box 13a is open. Although not shown, a plurality of gas burners are provided in the heating box 13a. Each gas burner burns gas.
[0094] The heating box 13a is disposed inside the housing 1. More specifically, the heating box 13a is disposed inside the housing 1 at a position lower than the housing 9. Furthermore, the front end of the heating box 13a faces the opening 10 of the first wall 1a. Thus, the interior of the heating box 13a communicates with the exterior of the housing 1 through the opening 10. Furthermore, although detailed illustrations are omitted, the interior of the heating box 13a communicates with the exhaust port 3a through an exhaust pipe. Thus, the air inside the heating box 13a is discharged from the exhaust port 3a to the exterior of the housing 1.
[0095] The grill door 13b is provided so as to be movable in the front-rear direction relative to the first wall 1a. Figure 1 As shown by the solid line, the grill door 13b moves to the rearmost position and can close the opening 10. The grill tray 13c is connected to the grill door 13b. Figure 1 As indicated by the two-dot chain line, the grill tray 13c is movable relative to the housing 1 in the forward and backward directions as the grill door 13b moves forward and backward. A cooking container containing food is placed on the grill tray 13c. This allows the heating grill 13 to heat food using the gas burners within the heating chamber 13a. Alternatively, the grill tray 13c may be a grilling grid, etc.
[0096] The stove burner 15 is disposed on the top plate 3. More specifically, the stove burner 15 is disposed on the top plate 3 to the left of the first and second guide marks 31 and 32, and even the first and second heating coils 5 and 7. Alternatively, the stove burner 15 may be disposed on the top plate 3 to the right of the first and second heating coils 5 and 7.
[0097] Furthermore, a fire support 15a is provided on the top plate 3 to surround the stove burner 15. A cooking container containing food is placed on the fire support 15a. The stove burner 15 burns gas to heat the food. A plurality of stove burners 15 may be provided on the top plate 3.
[0098] Although not shown in the figure, a control valve such as a heat adjustment valve is provided inside the housing 1. The control valve can adjust the amount of gas supplied to the heating grill 13 and the stove burner 15, etc.
[0099] like Figure 2 As shown, the control unit 17 is arranged inside the housing 1. More specifically, the control unit 17 is arranged below the housing 9 and to the right of the housing 9. The control unit 17 includes a circuit board 17a, a plurality of semiconductors 17b, a first blade 17c, and a second blade 17d.
[0100] The circuit board 17a is formed into a rectangular plate. Here, regarding the control unit 17, the circuit board 17a is arranged in a so-called vertical position inside the housing 1. The semiconductors 17b are arranged on the circuit board 17a. The first blade 17c is arranged between the circuit board 17a and the fifth wall 1e. The second blade 17d is arranged in front of the circuit board 17a, facing the first wall 1a. Alternatively, the circuit board 17a can be arranged in a so-called horizontal position inside the housing 1.
[0101] The control unit 17 includes a circuit board 17a electrically connected to a power source (not shown) provided outside the housing 1. The cooling fan 11, the first cooking temperature sensor 33, the second cooking temperature sensor 34, the first operating unit 41a, and the second operating unit 41b are also connected to the circuit board 17a.
[0102] Furthermore, the first coil body 51 of the first heating coil 5 and the second coil body 71 of the second heating coil 7 are each connected to the circuit substrate 17a. Although not shown in detail, when the first coil body 51 and the second coil body 71 are connected to the circuit substrate 17a, the ends of the first coil body 51 and the ends of the second coil body 71 are respectively extended from the inlet 93 or the outlet 94 to the outside of the housing 9. Thus, in the cooking device 100, the first heating coil 5 and the second heating coil 7 are arranged in the cooling chamber 60, that is, inside the housing 9, and the first coil body 51 and the second coil body 71 are connected to the circuit substrate 17a located outside the housing 9.
[0103] In addition, the circuit board 17a is connected to the heating grill 13, the oven burner 15, and the control valve.
[0104] The control unit 17 supplies power to the cooling fan 11 and controls the operation of the cooling fan 11. Furthermore, the control unit 17 supplies power to the first heating coil 5 and the second heating coil 7, respectively, and controls the operation of the first heating coil 5 and the second heating coil 7 according to the operation of the first operating unit 41a. Furthermore, the control unit 17 appropriately controls the operation of the first heating coil 5 and the second heating coil 7 during the heating of the food to be cooked based on the temperatures detected by the first cooking temperature sensor 33 and the second cooking temperature sensor 34. Furthermore, the control unit 17 can supply power to the first heating coil 5 and the second heating coil 7, respectively, and control their operation.
[0105] Furthermore, the control unit 17 controls the control valves according to the operations of the first operating unit 41 a and the second operating unit 41 b , thereby controlling the operation of the heating grill 13 and the stove burner 15 .
[0106] The cooking device 100 configured as described above can heat food using the first heating coil 5, the second heating coil 7, the heating grill 13, and the stove burner 15. When heating food using the first heating coil 5, the food is placed within the first guide mark 31 on the top plate 3. When heating food using the second heating coil 7, the food is placed within the second guide mark 32 on the top plate 3. Thus, the first heating coil 5 and the second heating coil 7 heat the food through electromagnetic induction. Furthermore, when heating food using the heating grill 13 or the stove burner 15, the food is placed on the grill tray 13c or the fire support 15a as described above. The heating grill 13 and the stove burner 15 then heat the food by burning gas supplied from a control valve.
[0107] Furthermore, with respect to the cooking device 100, for example, while the first heating coil 5 is heating an object to be cooked, the second heating coil 7 can be used to heat an object to be cooked that is different from the object to be cooked that is being heated by the first heating coil 5. Furthermore, while at least one of the first heating coil 5 and the second heating coil 7 is heating an object to be cooked, the heating grill 13 and the stove burner 15 can also heat a different object to be cooked. Similarly, while the heating grill 13 is heating an object to be cooked, the first and second heating coils 5 and 7 and the stove burner 15 can also heat different objects to be cooked. Furthermore, while the stove burner 15 is heating an object to be cooked, the first and second heating coils 5 and 7 and the heating grill 13 can also heat different objects to be cooked.
[0108] However, the first heating coil 5 and the second heating coil 7 generate heat during operation due to electromagnetic induction. Furthermore, the control unit 17 controls the operation of the first heating coil 5 and the second heating coil 7, causing each semiconductor 17b to generate heat. Therefore, when the first heating coil 5 and the second heating coil 7 are operating, the first heating coil 5, the second heating coil 7, and the control unit 17 reach high temperatures. Furthermore, while the first heating coil 5 and the second heating coil 7 are operating, if the heating grill 13 and the stove burner 15 are also operating, the control unit 17 is not only affected by the heat generated by the control of the operation of the first and second heating coils 5 and 7, but is also inevitably affected by the heat generated by the combustion of the gas in the heating grill 13 and the stove burner 15.
[0109] In this regard, regarding the cooking apparatus 100 , the cooling fan 11 operates to supply cooling air into the housing 1 while the cooking apparatus 100 is in operation, including when the first and second heating coils 5 and 7 are in operation.
[0110] The cooling air supplied to the interior of the housing 1 by the cooling fan 11 is as follows. Figure 2 As shown by the white arrow, the cooling air is introduced from the inlet 93 into the cooling chamber 60. The cooling air in the cooling chamber 60 flows between the top plate 3 and the first and second heating coils 5 and 7 to cool the first and second heating coils 5 and 7.
[0111] Here, the box body 9 is arranged inside the housing 1, and the cooling chamber 60 is formed inside the box body 9 using the top plate 3, the bottom wall 91 and the peripheral wall 92. Therefore, the cooling chamber 60 is a smaller space than the entire interior of the housing 1. Moreover, only the first and second heating coils 5 and 7 are arranged in the cooling chamber 60. In addition, a portion of the cooling air introduced into the cooling chamber 60 from the inlet 93 collides with the first connecting portion 91d and the second connecting portion 91e. As a result, the cooling air in the cooling chamber 60 can easily flow between the top plate 3 and the first and second heating coils 5 and 7. Therefore, with respect to the heating cooking device 100, the first and second heating coils 5 and 7 can be fully cooled in the cooling chamber 60 using the cooling air flowing between the top plate 3 and the first and second heating coils 5 and 7. As a result, with respect to the heating cooking device 100, it is possible to prevent the first and second heating coils 5 and 7 from reaching excessively high temperatures during operation.
[0112] In addition, regarding the heating cooking device 100, Figure 2 As indicated by the white arrows in FIG, a portion of the cooling air supplied into the housing 1 by the cooling fan 11 flows toward the control unit 17. Thus, the cooking device 100 can also appropriately cool the control unit 17 by the cooling air, thereby preventing the control unit 17, including the semiconductors 17b, from reaching an excessively high temperature during operation.
[0113] Moreover, regarding the heating cooking device 100, the cooling air for cooling the first and second heating coils 5 and 7 reaches the outlet 94 and is discharged from the cooling chamber 60 to the inside of the housing 1 using the outlet 94. The cooling air thus discharged to the inside of the housing 1 flows inside the housing 1 toward the exhaust port 3a of the top plate 3. In addition, the cooling air for cooling the control unit 17 also flows toward the exhaust port 3a. At this time, the heating box 13a and the stove burner 15 are also cooled by the cooling air flowing toward the exhaust port 3a inside the housing 1. Moreover, the cooling air reaching the exhaust port 3a is discharged from the exhaust port 3a to the outside of the housing 1, that is, to the outside of the heating cooking device 100.
[0114] Here, if Figure 4 As shown, in this cooking device 100, the first receiving recesses 911 and the first annular recess 912 of the first receiving portion 91a are simply recessed downward from the upper surface 901 of the first receiving portion 91a. The second receiving recesses 921 and the second annular recess 922 of the second receiving portion 91b are also simply recessed downward from the upper surface 903 of the second receiving portion 91b. Furthermore, the first receiving portion 91a does not have any vertically extending holes extending from the upper surface 901 to the lower surface 902, nor does the second receiving portion 91b have any vertically extending holes extending from the upper surface 903 to the lower surface 904.
[0115] Thus, the first receiving portion 91a prevents cooling air from flowing between the upper surface 901 and the lower surface 902 in the vertical direction of the housing 1. Similarly, the second receiving portion 91b prevents cooling air from flowing between the upper surface 903 and the lower surface 904 in the vertical direction of the housing 1. Therefore, in the cooking device 100, for example, cooling air within the cooling chamber 60 does not flow downward from the upper surfaces 901 and 903 of the first receiving portion 91a and the second receiving portion 91b toward the lower surfaces 902 and 904, thereby being directed out of the cooling chamber 60 from the lower surfaces 902 and 904. Furthermore, in the cooking device 100, cooling air outside the cooling chamber 60 does not flow upward from the lower surfaces 902 and 904 of the first receiving portion 91a and the second receiving portion 91b toward the upper surfaces 901 and 903, thereby being directed into the cooling chamber 60.
[0116] As a result, in the cooking device 100, cooling air is less likely to flow through the first coil body 51 of the first heating coil 5 and the second coil body 71 of the second heating coil 7 in the vertical direction of the housing 1 within the cooling chamber 60. Therefore, in the cooking device 100, wind noise is less likely to be generated due to the cooling air passing through the first coil body 51 and the second coil body 71 in the vertical direction of the housing 1.
[0117] Therefore, the cooking device 100 of the embodiment has excellent durability and can exhibit high quietness during operation.
[0118] In particular, in this cooking device 100, the first receiving portion 91a and the second receiving portion 91b are located at the same height on the bottom wall 91 of the housing 9, and are positioned above the main body 91c. Therefore, in this cooking device 100, when the first heating coil 5 and the second heating coil 7 are placed on the first receiving portion 91a and the second receiving portion 91b, respectively, the first heating coil 5 and the second heating coil 7 can be appropriately positioned close to the top plate 3. Thus, in this cooking device 100, the food to be cooked placed on the top plate 3 can be appropriately heated through electromagnetic induction by the first heating coil 5 and the second heating coil 7.
[0119] Furthermore, on the bottom wall 91, the first connecting portion 91d is integrally formed with the first receiving portion 91a and the main body 91c, and the second connecting portion 91e is integrally formed with the second receiving portion 91b and the main body 91c. Thus, the first receiving portion 91a, the second receiving portion 91b, the main body 91c, the first connecting portion 91d, and the second connecting portion 91e are integrally continuous on the bottom wall 91. Therefore, the cooking device 100 can easily be provided with the first receiving portion 91a, the second receiving portion 91b, the main body 91c, the first connecting portion 91d, and the second connecting portion 91e, and can also be easily formed on the bottom wall 91 and, moreover, on the housing 9.
[0120] Furthermore, the first connecting portion 91d is integrally formed with the first receiving portion 91a and the main body 91c, and the second connecting portion 91e is integrally formed with the second receiving portion 91b and the main body 91c. This reduces the height variations of the first receiving portion 91a and the second receiving portion 91b relative to the housing 9. Furthermore, the cooking device 100 also reduces the relative distance variations between the first receiving portion 91a and the second receiving portion 91b. Therefore, during operation, the cooking device 100 can suppress resonance and resonant vibrations between the first heating coil 5 and the second heating coil 7. In this regard, the cooking device 100 achieves a high level of quietness during operation.
[0121] In addition, the first connecting portion 91d is formed as a whole with the first loading portion 91a and the main body 91c, and the second connecting portion 91e is formed as a whole with the second loading portion 91b and the main body 91c, thereby suppressing the height deviation of the first loading portion 91a and the height deviation of the second loading portion 91b of each product in the box body 9.
[0122] Furthermore, the first connecting portion 91d and the second connecting portion 91e are formed into a flat cylindrical shape extending in the vertical direction. No holes or other similar portions are formed in the first connecting portion 91d and the second connecting portion 91e that radially penetrate the first connecting portion 91d and the second connecting portion 91e. Consequently, the cooking device 100 prevents cooling air from within the cooling chamber 60 from entering the interior of the first connecting portion 91d and flowing toward the lower surface 902 of the first receiving portion 91a. Furthermore, the cooking device 100 prevents cooling air from within the cooling chamber 60 from entering the interior of the second connecting portion 91e and flowing toward the lower surface 904 of the second receiving portion 91b.
[0123] As a result, in this cooking device 100, wind noise is not generated by cooling air flowing from the first connection portion 91d within the cooling chamber 60 toward the lower surface 902 of the first receiving portion 91a, nor is wind noise generated by cooling air flowing from the second connection portion 91e within the cooling chamber 60 toward the lower surface 904 of the second receiving portion 91b. Furthermore, in this cooking device 100, cooling air from outside the cooling chamber 60 does not flow from the lower surface 902 of the first receiving portion 91a via the first connection portion 91d into the cooling chamber 60, nor does it flow from the lower surface 904 of the second receiving portion 91b via the second connection portion 91e into the cooling chamber 60. In this regard, this cooking device 100 achieves high quietness during operation.
[0124] Furthermore, in the cooking device 100, the cooling air that collides with the first connecting portion 91d and the second connecting portion 91e in the cooling chamber 60 easily flows along the first connecting portion 91d and the second connecting portion 91e toward between the top plate 3 and the first heating coil 5 and the second heating coil 7. Therefore, in the cooking device 100, the flow rate of the cooling air that flows between the top plate 3 and the first heating coil 5 and the second heating coil 7 can be increased.
[0125] Furthermore, in the cooking device 100, the sealing member 95 seals the space between the peripheral wall 92 of the housing 9 and the top plate 3. Therefore, in the cooking device 100, the cooling air in the cooling chamber 60 leaks between the peripheral wall 92 and the top plate 3, thereby preventing noise from being generated.
[0126] Furthermore, the cooking device 100 includes a heating grill 13 and a stove burner 15 in addition to the first heating coil 5 and the second heating coil 7. Thus, the cooking device 100 can heat not only food that cannot be heated by electromagnetic induction, but also food that is difficult to heat quickly by electromagnetic induction, using the heating grill 13 and the stove burner 15. This improves the convenience of the cooking device 100.
[0127] The present invention has been described above based on the embodiments. However, the present invention is not limited to the above embodiments, and can be appropriately modified and applied without departing from the spirit and scope of the present invention.
[0128] For example, the cooking device 100 of the embodiment includes the first heating coil 5 and the second heating coil 7, but the present invention is not limited thereto and either the first heating coil 5 or the second heating coil 7 may be omitted. Furthermore, a heating coil may be further included in addition to the first heating coil 5 and the second heating coil 7.
[0129] In addition, in the heating cooking device 100 of the embodiment, the heating grill 13 and the oven burner 15 may be omitted.
[0130] In the cooking device 100 of the embodiment, the first loading portion 91a and the second loading portion 91b are located above the main body 91c on the bottom wall 91 of the cabinet 9. However, the present invention is not limited to this configuration, and the first loading portion 91a, the second loading portion 91b, and the main body 91c may be arranged coplanar and continuous.
[0131] In the cooking device 100 of the embodiment, the first connecting portion 91d is formed into a cylindrical shape extending in the vertical direction. However, the present invention is not limited thereto and the first connecting portion 91d may also be formed into a columnar shape connecting the first receiving portion 91a and the main body 91c in the vertical direction. The same applies to the second connecting portion 91e.
[0132] Furthermore, in the cooking device 100 of the embodiment, each end portion of the first coil body 51 and each end portion of the second coil body 71 protrude from the exterior of the housing 9 through the inlet 93 or outlet 94, respectively, and are connected to the circuit board 17a. However, this is not limiting, and guide holes may be formed relative to the main body 91c of the bottom wall 91 or the peripheral wall 92 to allow each end portion of the first and second coil bodies 51 and 71 to protrude from the exterior of the housing 9.
[0133] In the cooking device 100 of the embodiment, one cooling fan 11 is provided inside the housing 1. However, the present invention is not limited thereto, and a dedicated cooling fan for supplying cooling air to the control unit 17 may be provided in addition to the cooling fan 11.
[0134] In the cooking device 100 of the embodiment, the cooling fan 11 is located behind the housing 9 within the housing 1. However, this is not limiting, and the cooling fan 11 may also be located further rearward than the first wall 1a and further forward than the housing 9.
