[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and description thereof will not be repeated.

[0010] A range grill device 100 according to this embodiment will be described with reference to Figures 1 and 2. Figures 1 and 2 are diagrams showing the range grill device 100 according to this embodiment. The range grill device 100 is an example of a "heating cooker." Note that Figure 1 shows the appearance of the range grill device 100 placed in a kitchen, viewed from above and diagonally in front of the right. Figure 2 shows the appearance of only the range grill device 100, viewed from above and diagonally in front of the right.

[0011] The range grill device 100 is box-shaped. The range grill device 100 is placed, for example, in a kitchen. The range grill device 100 heats and cooks a first object to be heated H1. The first object to be heated H1 is, for example, a pot containing food. Specifically, the first object to be heated H1 is placed on the top surface of the range grill device 100 and is grilled. The range grill device 100 also heats and cooks a second object to be heated H2. The second object to be heated H2 is, for example, a plate on which food is placed. Specifically, the second object to be heated H2 is placed inside the range grill device 100 and is microwave-cooked.

[0012] The microwave grill device 100 includes a first heating unit 20, a microwave cooking chamber 70, a microwave supply unit 89, an operation unit 40, a support unit 80, a control unit 50, and a memory unit 55. The microwave supply unit 89 is an example of a second heating unit.

[0013] In this embodiment, the side of the range grill device 100 where the operation unit 40 is located is defined as the front side of the range grill device 100, and the opposite side is defined as the rear side of the range grill device 100. Furthermore, the right side when viewing the range grill device 100 from the front is defined as the right side of the range grill device 100, and the opposite side is defined as the left side of the range grill device 100. Note that these directions do not limit the orientation of the range grill device 100 of the present invention when in use. Hereinafter, the front-to-rear direction of the range grill device 100 will also be referred to as a first direction D1, the left-to-right direction of the range grill device 100 will also be referred to as a second direction D2, and the up-to-down direction of the range grill device 100 will also be referred to as a third direction D3. The first direction D1, the second direction D2, and the third direction D3 are all perpendicular to each other.

[0014] The microwave cooking chamber 70 is box-shaped. Specifically, the microwave cooking chamber 70 has a right wall 71, a left wall 72, an upper wall 73 (FIG. 4), a lower wall 74, a rear wall 75, and a front door 76. The microwave cooking chamber 70 is an example of a heating chamber. Specifically, the microwave cooking chamber 70 has a heating chamber inside.

[0015] The front door 76 is a substantially rectangular plate-like member. The front door 76 can open and close an opening 701 at the front of the microwave cooking chamber 70. Specifically, the front door 76 moves between a closed position and an open position. The open position indicates a position where the front door 76 opens the opening 701. On the other hand, the closed position indicates a position where the front door 76 covers the opening 701. Typically, the open position indicates a position where the front door 76 is pulled forward relative to the microwave cooking chamber 70.

[0016] When the front door 76 opens the opening 701, the second object to be heated H2 can move between the inside and outside of the microwave cooking chamber 70. On the other hand, when the front door 76 covers the opening 701, the second object to be heated H2 is contained inside the microwave cooking chamber 70.

[0017] The microwave supply unit 89 supplies microwaves to the interior of the microwave cooking chamber 70. Specifically, the microwave supply unit 89 has a radiation chamber, a magnetron, a waveguide, a rotating antenna, and an antenna motor. The magnetron generates microwaves. The waveguide propagates the microwaves generated by the magnetron to the radiation chamber. The rotating antenna is housed in the radiation chamber. The antenna motor drives the rotating antenna. The rotating antenna stirs the microwaves and supplies them to the interior of the microwave cooking chamber 70.

[0018] The first heating unit 20 heats and cooks the first object to be heated H1. The first heating unit 20 includes a plate 30, a grill chamber 39, multiple radiant heaters, a right panel 61, a left panel 62, and a front frame 63. Specifically, the first heating unit 20 includes a first radiant heater 21, a second radiant heater 22, a third radiant heater 23, a fourth radiant heater 24, and a fifth radiant heater 25. Each of the first radiant heater 21, the second radiant heater 22, the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25 generates heat by passing a direct current through a nichrome wire. Each of the first radiant heater 21, the second radiant heater 22, the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25 is ring-shaped.

[0019] The first radiant heater 21 and the second radiant heater 22 are disposed forward of the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25. The second radiant heater 22 is disposed to the right of the first radiant heater 21. The fourth radiant heater 24 is disposed to the right of the third radiant heater 23. The fifth radiant heater 25 is disposed to the right of the fourth radiant heater 24. In this embodiment, the first radiant heater 21 and the second radiant heater 22 are an example of a first heating device. The third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25 are an example of a second heating device.

[0020] The grill chamber 39 includes a right wall 31 (FIG. 4), a left wall 32, a bottom wall 33 (FIG. 4), a front wall 34, and a rear wall 35 (FIG. 4). The grill chamber 39 is located above the microwave cooking chamber 70. The grill chamber 39 houses the first radiant heater 21, the second radiant heater 22, the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25. In this embodiment, the right panel 61 covers the right wall 31. The left panel 62 covers the left wall 32. Specifically, the right panel 61 includes a first panel 61A and a second panel 61B. The first panel 61A covers the right wall 31 of the grill chamber 39. The second panel 61B is disposed below the first panel 61A. The first panel 61A and the second panel 61B may be integrally formed. The left panel 62 is also similar to the right panel 61.

[0021] The plate 30 is a substantially rectangular plate-like member. The plate 30 is made of, for example, glass. The plate 30 is provided above the first radiant heater 21, the second radiant heater 22, the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25, and covers the upper sides of the first radiant heater 21, the second radiant heater 22, the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25. A first object to be heated H1 is placed on the plate 30.

[0022] The support section 80 supports the lower part of the first heating section 20. Specifically, the support section 80 supports a plurality of radiant heaters. Details of the support section 80 will be described later.

[0023] Operation information is input to the operation unit 40. The operation information includes, for example, information for turning the power of the radiant heater on / off, adjusting the output of the radiant heater, turning the power of the microwave supply unit 89 on / off, and adjusting the output of the microwave supply unit 89. The operation unit 40 is disposed in front of the grill chamber 39. The operation unit 40 is also disposed in front of the plate 30. The operation unit 40 is further disposed above the front door 76. In other words, the operation unit 40 is disposed in front of the plate 30 and in front of the front end of the opening 701 on the front side of the microwave cooking chamber 70.

[0024] Therefore, compared to when the operating unit 40 is provided behind the microwave cooking chamber 70, the area of the plate 30 can be made larger.

[0025] The operation unit 40 includes an operation housing 400, a first dial 41, a second dial 42, a third dial 43, a fourth dial 44, and an operation panel 45. In detail, the first dial 41 is operated by the cook to receive operation information for the first radiant heater 21. The second dial 42 is operated by the cook to receive operation information for the third radiant heater 23. The third dial 43 is operated by the cook to receive operation information for the second radiant heater 22. Furthermore, the fourth dial 44 is operated by the cook to receive operation information for the fifth radiant heater 25.

[0026] The operation panel 45 is operated by the cook to receive operation information for the radiant heater or the microwave supply unit 89. Specifically, the operation panel 45 includes various keys and a display device. The display device displays information related to the first heating unit 20 and the microwave supply unit 89. For example, the display device displays the heating temperature and heating power of the first heating unit 20. The display device includes a liquid crystal panel. The operation panel 45 is an example of a display unit.

[0027] The first dial 41, the second dial 42, the third dial 43, the fourth dial 44, and the operation panel 45 are arranged on an operation housing 400. The operation housing 400 is provided to protrude from the front end of the front door 76. Details of the operation housing 400 will be described later.

[0028] The storage unit 55 (FIG. 2) is composed of a RAM (Random Access Memory) and a ROM (Read Only Memory). The storage unit 55 stores a control program for controlling the operation of each part of the range grill device 100.

[0029] The control unit 50 (FIG. 2) is a hardware circuit including a processor such as a CPU (Central Processing Unit). The control unit 50 executes a control program stored in the storage unit 55. This causes the control unit 50 to control the first heating unit 20 and the microwave supply unit 89. For example, the control unit 50 outputs drive information to the first heating unit 20 based on operation information. For example, the control unit 50 repeatedly turns on the power of the first radiant heater 21 for a first predetermined period and turns it off for a second predetermined period. More specifically, when the cook inputs operation information into the operation panel 45, the control unit 50 controls the microwave supply unit based on the operation information. For example, the control unit 50 turns on the power of the microwave supply unit 89 for a third predetermined period.

[0030] The driving information may further include the driving state of each of the multiple radiant heaters and the driving state of the microwave supply unit 89. The driving information may further include the number of radiant heaters being driven, or the ON / OFF state of the power supply of the radiant heaters.

[0031] Next, the support part 80 will be described with reference to Fig. 1 to Fig. 4. Fig. 3 is a side view of the range grill device 100 viewed from the right side. Fig. 4 is a side view of the range grill device 100 viewed from the right side with the right panel 61 and left panel 62 removed. Fig. 5 is a diagram showing the positional relationship between the first heating part 20, the operating part 40, and the support part 80. Fig. 6 is an exploded perspective view showing the positional relationship between the first heating part 20, the operating part 40, and the support part 80.

[0032] 3 to 6, the support part 80 has mounting parts 81A and 81B and pillar parts 82A and 82B. The first heating part 20 is mounted on the mounting part 81A and the mounting part 81B. The pillar parts 82A and 82B extend downward from the mounting part 81A and the mounting part 81B, respectively.

[0033] Specifically, the placing portions 81A and 81B are provided below the lower wall 33 in contact with the lower wall 33. The placing portions 81A and 81B are provided so as to extend across the entire width of the first heating section 20 in the left-right direction (second direction D2).

[0034] In this embodiment, the width of the mounting portions 81A and 81B in the front-rear direction (first direction D1) is shorter than the width of the first heating portion 20 (plate 30) in the front-rear direction (first direction D1). In other words, the width of the mounting portions 81A and 81B in the front-rear direction (first direction D1) accounts for only a portion of the width of the first heating portion 20 (plate 30) in the front-rear direction (first direction D1). In this way, the first heating portion 20 can be supported with a simple configuration. Furthermore, the first heating portion 20 and the support portion 80 can be moved together, which expands the options for where the range grill device 100 can be installed.

[0035] As shown in FIG. 4, the mounting portion 81A extends in the left-right direction (second direction D2) below the first radiant heater 21 and the second radiant heater 22 (first heating device). The mounting portion 81A is an example of a first mounting portion. The mounting portion 81B extends in the left-right direction (second direction D2) below the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25 (second heating device). The mounting portion 81B is an example of a second mounting portion. In this way, the mounting portions 81A and 81B are positioned apart from each other in the front-rear direction (first direction D1). Therefore, the mounting portions 81A and 81B can support the first heating portion 20 while balancing the weight in the front-rear direction (first direction D1).

[0036] More specifically, the mounting portion 81A is provided at a position not including position C1, which indicates the center of the first radiant heater 21 and the center of the second radiant heater 22, in the front-rear direction (first direction D1). Specifically, the mounting portion 81A is provided on the front side of position C1. The mounting portion 81B is provided at a position including position C2, which indicates the center of the third radiant heater 23, the center of the fourth radiant heater 24, and the center of the fifth radiant heater 25, in the front-rear direction (first direction D1). Specifically, the mounting portion 81B is provided across the front side of the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25, including position C2, and the rear side of the third radiant heater 23, the fourth radiant heater 24, and the fifth radiant heater 25. In other words, the mounting portion 81B passes below position C2. The placement portion 81B is provided so as to support the rear side of the second heating device.

[0037] Therefore, the placement portions 81A and 81B can support the first heating unit 20 while balancing the weight of the first heating device, the second heating device, and the operation unit 40 in the front-rear direction (first direction D1).

[0038] As shown in Figures 4 and 6, the pillar portion 82A includes a pair of pillars 82a and 82b. The pair of pillars 82a and 82b of the pillar portion 82A face each other in the left-right direction (second direction D2). The pillar portion 82B includes a pair of pillars 82a and 82b. The pair of pillars 82a and 82b of the pillar portion 82B face each other in the left-right direction (second direction D2). The widths of the pillar portions 82A and 82B in the front-rear direction (first direction D1) are the same as the widths of the mounting portions 81A and 81B in the front-rear direction (first direction D1), respectively.

[0039] The microwave cooking chamber 70 is disposed between the pillars 82a and 82b of the pillar section 82A, and between the pillars 82a and 82b of the pillar section 82B. The pillar 82a of the pillar section 82A is connected to the right wall 71 of the microwave cooking chamber 70. The pillar 82a of the pillar section 82B is connected to the right wall 71 of the microwave cooking chamber 70. The pillar 82b of the pillar section 82A is connected to the left wall 72 of the microwave cooking chamber 70. The pillar 82b of the pillar section 82B is connected to the left wall 72 of the microwave cooking chamber 70.

[0040] For example, pillars 82A and 82B are attached directly to microwave cooking chamber 70. This allows first heating section 20 to be disposed above microwave cooking chamber 70 with a small number of parts.

[0041] In this embodiment, the mounting portion 81A and the mounting portion 81B have the same shape. Furthermore, the column portion 82A and the column portion 82B have the same shape. Specifically, the column 82a in the column portion 82A and the column 82a in the column portion 82B have the same shape. The column 82b in the column portion 82A and the column 82b in the column portion 82B have the same shape. Furthermore, a pair of columns 82a and 82b have the same shape. That is, the column 82a in the column portion 82A, the column 82a in the column portion 82B, the column 82b in the column portion 82A, and the column 82b in the column portion 82B each have the same shape. Therefore, multiple identical parts can be easily manufactured, reducing manufacturing costs.

[0042] In this embodiment, the number and combination of mounting portions and pillar portions provided in the range grill device 100 are not particularly limited. For example, two mounting portions and a pair of pillar portions may be provided, or one mounting portion may be provided with two or more pairs of pillar portions. The widths of the mounting portions and pillar portions in the front-rear direction (first direction D1) may be different from each other. Furthermore, the widths of the mounting portions and pillar portions in the front-rear direction (first direction D1) may occupy the entire width of the first heating portion 20 (plate 30) in the front-rear direction (first direction D1).

[0043] Next, the panel member 60 provided in the range grill device 100 will be described with reference to FIGS.

[0044] In this embodiment, the vertical length (third direction D3) of pillars 82A and 82B is longer than the vertical length (third direction D3) of microwave cooking chamber 70. As a result, as shown in Fig. 4, spaces S1 are created between the upper wall 73 of microwave cooking chamber 70 and the lower wall 33 of grill chamber 39, and between the upper wall 73 of microwave cooking chamber 70 and mounting portions 81A, 81B.

[0045] In the range grill device 100, the panel member 60 is provided so as to block at least a portion of the front side of the space S1. Specifically, in the range grill device 100, the operation housing 400 and the front door 76 are positioned apart from each other in the up-and-down direction (third direction D3). The panel member 60 is provided between the operation housing 400 and the front door 76. The panel member 60 is a substantially rectangular plate-like member. Typically, the panel member 60 is attached above the opening 701 in the range heating cooking chamber 70. The operation housing 400 and the panel member 60 are provided so as to block the front side of the space S1.

[0046] Heat generated from first heating unit 20 by heating and heat generated from microwave cooking chamber 70 by heating by microwave supply unit 89 is transferred to space S1. As a result, space S1 is prone to becoming hot. Therefore, by providing panel member 60, it is possible to block the forward movement of hot air in space S1. As a result, heat is less likely to be transferred to a cook positioned in front of operating unit 40, allowing the cook to operate operating unit 40 comfortably.

[0047] Next, how the range grill device 100 is viewed from diagonally above the front will be described with reference to Figures 3 to 5 and 7. Figure 7 is a diagram showing the range grill device 100 as viewed from diagonally above the front.

[0048] 3, the operation housing 400 has a first inclined surface F1 that slopes upward from the lower surface of the operation housing 400 toward the front side. By providing the first inclined surface F1, for example, when a cook looks down at the operation panel 45 from diagonally above in front, the panel member 60 becomes more noticeable.

[0049] Typically, the front end 761 of the front door 76 is located forward of an imaginary plane F3 that is an extension of the first inclined surface F1. Therefore, when a cook looks down at the operation panel 45 from diagonally above and in front, the front door 76, as well as the panel member 60, are easily noticeable.

[0050] Furthermore, in the range grill device 100, the positions of the front end 761 of the front door 76 and the front end 601 of the panel member 60 coincide in the front-to-rear direction (first direction D1). This makes it possible to prevent a decrease in visibility between the panel member 60 and the front door 76, while providing a sense of visual unity between the panel member 60 and the front door 76.

[0051] Next, details of the operating unit 40 will be described with reference to Figures 3 to 5 and Figures 8 to 10. Figure 8 is a diagram showing the rear side of the operating unit 40. Figure 9 is an exploded perspective view of the operating unit 40. Figure 10 is an exploded perspective view of the operating unit 40 from a different angle. In addition to the operating unit 40, Figures 8 to 10 also show the front frame 63.

[0052] 8 to 10, the operation housing 400 includes a base portion 401, a storage portion 402, and a cover portion 403. The base portion 401 forms the bottom of the operation housing 400. A lower surface and a first inclined surface F1 are formed on the base portion 401. For example, the base portion 401 is made of resin.

[0053] The storage section 402 is disposed above the base section 401. The first dial 41, the second dial 42, the third dial 43, the fourth dial 44, and the operation panel 45 are disposed in the storage section 402. In detail, the first dial 41, the second dial 42, the third dial 43, the fourth dial 44, and the display device (display surface) of the operation panel 45 are disposed so as to be exposed from the storage section 402. In the operation housing 400, the space surrounded by the storage section 402 and the base section 401 stores everything except the display device (display surface) of the operation panel 45. For example, the storage section 402 is made of resin.

[0054] The accommodation section 402 also has a second inclined surface F2. As shown in FIGS. 3 to 5, the second inclined surface F2 is inclined in the vertical direction (third direction D3) relative to the plate 30 of the first heating section 20. Specifically, the second inclined surface F2 is inclined diagonally downward toward the front side. A display device of the operation panel 45 is disposed on the second inclined surface F2. As a result, when the length in the front-rear direction (first direction D1) is the same as that of the operation housing 400, the vertical length of the display device can be made longer compared to when the display device of the operation panel 45 is disposed on a horizontal surface. This allows the display area of the operation panel 45 to be increased.

[0055] The cover portion 403 covers the accommodation portion 402 and forms the second inclined surface F2. For example, the cover portion 403 is made of metal.

[0056] Next, the attachment of the operation housing 400 will be described with reference to FIGS.

[0057] As shown in FIGS. 4, 5, 8, and 10, the operation housing 400 has a pair of connecting portions 410. The pair of connecting portions 410 are connected to the first heating unit 20. Specifically, the pair of connecting portions 410 are provided on both ends of the base portion 401 of the operation housing 400 in the left-right direction (second direction D2). Each of the pair of connecting portions 410 is provided to protrude from the rear side of the operation housing 400. The pair of connecting portions 410 are attached to the front frame 63. Specifically, the front frame 63 includes a first support member 63A and a second support member 63B. The first support member 63A contacts the rear surface and the bottom surface of the base portion 401. The first support member 63A has a shape that extends along the pair of connecting portions 410. The second support member 63B is disposed on the rear side of the first support member 63A.

[0058] As a result, the operation housing 400 is supported at both ends in the left-right direction (second direction D2) relative to the first heating unit 20. Therefore, the operation housing 400 can be supported more stably than when only the bottom surface of the operation housing 400 is supported.

[0059] Specifically, each of the pair of connecting portions 410 has a shape that extends in the vertical direction (third direction D3). Typically, each of the pair of connecting portions 410 is a substantially rectangular plate-like member. The connecting portion 410 has at least two mounting portions 411 that are attached to the first heating unit 20. For example, the connecting portion 410 is screwed to the first support member 63A. That is, the connecting portion 410 is provided with a through-hole through which the screw passes as the mounting portion 411. The two mounting portions 411 are arranged side by side in the vertical direction (third direction D3). As a result, the connecting portion 410 is supported relative to the first heating unit 20 at at least two points that are aligned in the vertical direction (third direction D3). As a result, the operation housing 400 is less likely to rotate in the vertical direction (third direction D3), and the posture of the operation unit is more likely to be stable.

[0060] As shown in FIGS. 8 and 9, the operation housing 400 has hooks 421 that are hooked onto the first support member 63A and the second support member 63B located on the front side of the first heating unit 20. Specifically, one or more through holes 341 are provided in the first support member 63A. Hooks 421 corresponding to the through holes 341 are provided on the rear surface of the operation housing 400. In this embodiment, the hooks 421 are provided on the base part 401, but may be provided on the accommodation part 402 or the cover part 403. The hooks 420 have a shape that is curved convexly upward. The hooks 421 are hooked onto the edge of the through holes 341. Note that the hooks 421 may be hooked onto the second support member 63B together with the edge of the through holes 341.

[0061] The hook 421 makes it difficult for the operation housing 400 to move in the front-rear direction (first direction D1) relative to the front wall 34, making it easier to stabilize the attitude of the operation unit.

[0062] As shown in FIGS. 8 to 10 , the operation housing 400 has a side wall portion 430. Typically, the side wall portion 430 is provided on both ends of the operation housing 400 in the left-right direction (second direction D2) of the storage portion 402. The side wall portion 430 has ventilation holes 431. The ventilation holes 431 are formed by, for example, a plurality of slits 432 penetrating the side wall portion 430. Note that the ventilation hole 431 may be a single through-hole penetrating the side wall portion 430. The ventilation hole 431 is an example of a first ventilation hole. The size, shape, and number of the slits 432 are not particularly limited.

[0063] Providing the ventilation holes 431 in the operation housing 400 improves the breathability of the operation housing 400. As a result, it is possible to suppress a temperature rise in the operation housing 400 due to heating by the first heating unit 20 or the microwave supply unit 89. Note that the ventilation holes 431 are not limited to being provided on the side wall 430, and may be provided on any surface of the operation housing 400. For example, the ventilation holes 431 may be provided on the bottom surface of the operation housing 400.

[0064] 9, the operation housing 400 has a blower fan 440 that supplies air to the operation housing 400. In this embodiment, the operation housing 400 has two blower fans 440A and 440B. By providing the blower fan 440 in the operation housing 400, the air inside the operation housing 400 can be efficiently exchanged, thereby improving the heat dissipation performance of the operation housing 400. Typically, the blower fans 440A and 440B are controlled by the control unit 50.

[0065] Furthermore, operation housing 400 has air supply chamber 450 connected to ventilation hole 431. In this embodiment, operation housing 400 has two air supply chambers 450A and 450B. Air supply chamber 450A is connected to ventilation hole 431 provided in side wall portion 430 on the right side of operation housing 400. Air supply chamber 450B is connected to ventilation hole 431 provided in side wall portion 430 on the left side of operation housing 400. In other words, air supply chamber 450A is provided on the right side of operation housing 400. Air supply chamber 450B is provided on the left side of operation housing 400.

[0066] Specifically, operation housing 400 has partition 451A facing right side wall 430 and partition 451B facing left side wall 430. Partition 451A and partition 451B are provided in storage section 402. Partition 451A is located to the left of right side wall 430. Partition 451B is located to the right of left side wall 430. Therefore, air supply chamber 450A is formed between right side wall 430 and partition 451A. Air supply chamber 450B is formed between left side wall 430 and partition 451B.

[0067] Air supply chamber 450A has ventilation hole 452A different from ventilation hole 431. Air supply chamber 450B has ventilation hole 452B different from ventilation hole 431. Furthermore, blower fan 440A is arranged in air supply chamber 450A. Blower fan 440B is arranged in air supply chamber 450B. When ventilation fans 440A and 440B are driven, air is supplied to air supply chamber 450A or air supply chamber 450B from ventilation hole 431, respectively, and air in air supply chamber 450A or air supply chamber 450B is exhausted from air supply chamber 450A or air supply chamber 450B through ventilation hole 452A or ventilation hole 452B. In this way, air can be efficiently supplied to the inside of operation housing 400. Ventilation holes 452A and 452B are examples of second ventilation holes.

[0068] For example, ventilation hole 452A is provided in partition section 451A. Ventilation hole 452B is provided in partition section 451B. In other words, ventilation hole 452A faces right-side ventilation hole 431 in the left-right direction (second direction D2). Ventilation hole 452B faces left-side ventilation hole 431 in the left-side direction (second direction D2). Therefore, the air path from right-side ventilation hole 431 to ventilation hole 452A and the air path from left-side ventilation hole 431 to ventilation hole 452B are linear, making it easier for air to pass through air supply chamber 450A or air supply chamber 450B.

[0069] In the present embodiment, ventilation hole 431 is provided further forward than ventilation hole 452A and ventilation hole 452B. Specifically, ventilation hole 431 is arranged on the front side in the front-rear direction (first direction D1) on side wall portion 430. Ventilation hole 452A and ventilation hole 452B are arranged on the rear side in the front-rear direction (first direction D1). By providing ventilation hole 431 in this manner at a position farther away from the heat sources of first heating unit 20 and microwave supply unit 89 than ventilation hole 452A and ventilation hole 452B, cooler air is more easily supplied into operation housing 400.

[0070] Furthermore, operation housing 400 has a plurality of ventilation holes 470 on its underside. Air that has passed through air supply chamber 450A or air supply chamber 450B is exhausted to the outside of operation housing 400 through ventilation holes 470. Ventilation holes 470 are an example of a third ventilation hole. For example, ventilation holes 470 are located behind end 601 on the front side of panel member 60. Therefore, the air exhausted from ventilation holes 470 is unlikely to directly hit the cook.

[0071] Next, air supply chamber 450A and air supply chamber 450B will be described with reference to Figures 8 to 12. Figure 11 is an enlarged view of air supply chamber 450A. Figure 12 is an enlarged view of air supply chamber 450B.

[0072] 8 to 12, the orientation of blower fan 440A arranged in air supply chamber 450A is different from the orientation of blower fan 440B arranged in air supply chamber 450B. As a result, the air blown by blower fan 440A and the air blown by blower fan 440B are generated at different positions inside operation housing 400. Therefore, it becomes easier for air to pass over a wider range inside operation housing 400.

[0073] For example, blower fan 440A is arranged so as to extend along the front-rear direction (first direction D1). Blower fan 440B is arranged so as to extend along a direction intersecting the front-rear direction (first direction D1). Typically, blower fan 440B is arranged so as to extend along the up-down direction (third direction D3). Specifically, blower fan 440B is a centrifugal fan (sirocco fan). The rotation shafts of blower fan 440A and blower fan 440B are arranged so as to extend along the front-rear direction (first direction D1) and the up-down direction (third direction D3), respectively.

[0074] Ventilation hole 452A of air supply chamber 450A has a shape that extends in the vertical direction (third direction D3). Ventilation hole 452B of air supply chamber 450B has a shape that extends in the front-to-rear direction (first direction D1). By making the shapes of ventilation hole 452A and ventilation hole 452B correspond to the directions of blower fan 440A and blower fan 440B, respectively, air can be efficiently supplied into operation housing 400.

[0075] For example, ventilation hole 452A is provided on the first heating unit 20 side (rear side) of operation housing 400. Ventilation hole 452B is provided on the second inclined surface F2 side. This makes it possible to suppress temperature rise on the front side of plate 30, which tends to heat up, and on second inclined surface F2, which is the operation surface of the operation unit.

[0076] The ventilation hole 431 includes partition walls 460 that separate the plurality of slits 432 from one another. Partition wall 460 is provided on the air supply chamber 450 side of side wall portion 430. Partition wall 460 has a shape that curves toward the opposite side from blower fan 440A or blower fan 440B. For example, partition wall 460 curves toward the front side. This allows air supplied to air supply chamber 450A through slit 432 to move toward the front side along partition wall 460. This allows cool air to be distributed over a wider area, and makes blower fan 440A less visible from outside operation housing 400.

[0077] As shown in FIG. 4, in this embodiment, the range grill device 100 includes a wiring unit 501. A cable CA extending from the operation unit 40 is wired to the wiring unit 501. For example, the wiring unit 501 is a terminal block. The wiring unit 501 is disposed on the opposite side of the operation unit 40 with respect to the first heating unit 20. Specifically, the wiring unit 501 is attached to the rear side of the rear wall 35 of the grill chamber 39. In addition, a wiring hole 342 is provided on the rear surface of the operation housing 400, through which the cable CA extending from the operation unit 40 passes. The cable CA that passes through the wiring hole 342 passes, for example, below the grill chamber 39, and is wired to the wiring unit 501.

[0078] In this way, by providing the wiring section 501 outside the operation section 40, it becomes easier to ensure a ventilation path inside the operation housing 400.
