DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] <1. First embodiment> A cooking device 1000 according to a first embodiment will be described with reference to the drawings.

[0009] The cooking device 1000 is a device for cooking ingredients. In one embodiment, the cooking device 1000 is a cooking device for grilling and cooking ingredients, such as grilled meat or yakitori.

[0010] 1, the cooking device 1000 may be a tabletop cooking device in which the entire cooking device 1000 can be placed on the top plate of a table T. Alternatively, the cooking device 1000 may be a built-in cooking device in which most of the cooking device 1000 can be housed in a housing provided under the top plate of the table T.

[0011] <1-1. Structure of cooking device> As shown in FIG. 2, the cooking device 1000 mainly includes a drain pan 10, a gas pipe 20, a casing 30, a main burner 40, a hot plate receiver 50, a hot plate 60, a cooking utensil 70, a bottom plate 80, a burner support member 90, a protective member 100, an ignition device 110, and a drain pan support member 120.

[0012] The drain pan 10 includes a bottom wall 11, an inner peripheral wall 12, and an outer peripheral wall 13. The bottom wall 11 is donut-shaped with a circular opening in the center. The inner peripheral wall 12 is integrated with the bottom wall 11 and rises from the inner edge of the opening of the bottom wall 11. The inner peripheral wall 12 is cylindrical with a diameter that gradually decreases toward the top. The space surrounded by the inner peripheral wall 12 and the opening of the bottom wall 11 are openings 12a for arranging the main burner 40. The outer peripheral wall 13 is integrated with the bottom wall 11 and rises from the outer edge of the bottom wall 11. The upper part of the outer peripheral wall 13 spreads outward. The upper part of the outer peripheral wall 13 has a step 13a for arranging the cooking utensil 70.

[0013] The gas pipe 20 is disposed outside the drain pan 10. The gas pipe 20 is coupled to the main burner 40 and the pilot burner 112 of the ignition device 110 (see FIG. 3).

[0014] The casing 30 covers the periphery of the outer wall 13 of the drain pan 10 and the gas pipe 20 .

[0015] The main burner 40 is supported by a burner support member 90. The central axis of the main burner 40 approximately coincides with the center of the opening 12a. The main burner 40 has a length that starts below the opening 12a, passes through the opening 12a, and reaches above the upper end of the inner circumferential wall 12.

[0016] The hot plate receiver 50 is placed on the upper end of the inner peripheral wall 12 of the drain pan 10 .

[0017] The hot plate 60 is placed on the hot plate receiver 50 and is located above the main burner 40.

[0018] Cooking utensil 70 is placed on step 13a of outer peripheral wall 13 and is located above hot plate 60. Cooking utensil 70 is a member for placing food on, such as a net or a grate. Cooking utensil 70 shown in Fig. 2 is a net with a central region raised higher than the outer edge (i.e., curved obliquely upward from the outer edge toward the center).

[0019] The air around the main burner 40 is heated by the flame emitted from the main burner 40, generating hot air. The flame emitted from the main burner 40 also heats the hot plate 60. The heated hot plate 60 emits radiant heat. The hot air and the radiant heat from the hot plate 60 heat the cooking utensil 70 and the food on the cooking utensil 70.

[0020] The bottom plate 80 is disposed below the bottom wall 11 of the drain pan 10 and spaced apart from the bottom wall 11. The bottom plate 80 is fixed to the casing 30 with screws.

[0021] 3, the drain pan support member 120 is disposed between the bottom wall 11 and the bottom plate 80 of the drain pan 10, and is fixed to the bottom plate 80 and the protective member 100 with screws. The drain pan support member 120 is in contact with the bottom wall 11 of the drain pan 10, and supports the drain pan 10 from below. The drain pan support member 120 is made of a long U-shaped member. The drain pan support member 120 extends horizontally, passing below the opening 12a, so as to be perpendicular to the central axis of the opening 12a.

[0022] The burner support member 90 supports the main burner 40. The burner support member 90 is fixed to the drain pan support member 120 by screws. Therefore, the burner support member 90 is fixed to the bottom plate 80 via the drain pan support member 120, and is immovable relative to the bottom plate 80.

[0023] The burner support member 90 includes an upper wall 91 and two side walls 92, 93 extending downward from the upper wall 91. The burner support member 90 has an inverted U-shape. The two side walls 92, 93 are perpendicular to the upper wall 91. The two side walls 92, 93 are parallel to each other.

[0024] The upper wall 91 has an opening. The center of the opening of the upper wall 91 is positioned on the central axis of the opening 12a. The main burner 40 is inserted into the opening of the upper wall 91 and fixed to the upper wall 91.

[0025] The side wall 92 is parallel to the side wall of the drain pan support member 120 and extends above the side wall of the drain pan support member 120. The side wall 92 is disposed at a position horizontally offset from the central axis of the opening 12a.

[0026] The width of the side wall 92 is greater than that of the upper wall 91. As shown in Figures 3 and 4, the corners at both ends in the width direction of the side wall 92 are cut diagonally. That is, the corners at both ends in the width direction of the side wall 92 form inclined surfaces 92a that slope diagonally downward.

[0027] 4, the upper portion of the burner support member 90 (upper portions of the side walls 92, 93 and the upper wall 91) is disposed within the opening 12a. Two inclined surfaces 92a of the side wall 92 are in contact with the inner surface of the inner circumferential wall 12 of the drain pan 10. The inclination angle of the inclined surfaces 92a is preferably the same as or close to the inclination angle of the inner circumferential wall 12.

[0028] 3 and 5, the protective member 100 is disposed under the bottom plate 80. The protective member 100 blocks radiant heat radiated downward from components whose temperatures become high, such as the main burner 40 and the hot plate 60, during use of the cooking device 1000. This makes it possible to protect an object (for example, the top plate of a table T) disposed under the cooking device 1000 from radiant heat.

[0029] The protective member 100 is fixed to the bottom plate 80 with screws. Legs 150 (see FIG. 2) are connected to the casing 30. The legs 150 are in contact with the top plate of the table T. The protective member 100 is floating above the top plate of the table T. In the case of a built-in type cooking appliance 1000, the legs 150 are not necessary.

[0030] The protective member 100 is made of a plate material. The protective member 100 is preferably made of a metallic material having a luster, and is preferably made of stainless steel having a luster. An example of the stainless steel having a luster is stainless steel that has been given a surface finish of 2B or higher. Note that stainless steel that has been given a 2B finish is stainless steel that has been cold-rolled, annealed, pickled, and then skin-pass rolled.

[0031] 3 and 5, the ignition device 110 is disposed on the bottom plate 80. The ignition device 110 includes an ignition plug 111, a pilot burner 112, a holder 113, and a guide 114.

[0032] The ignition plug 111 is a device for igniting the pilot burner 112 by, for example, a spark. The pilot burner 112 is a burner for igniting the air-fuel mixture ejected from the main burner 40.

[0033] The ignition plug 111 and the pilot burner 112 are held by a holder 113. The holder 113 is fixed to a guide 114 by a screw. The guide 114 is fixed to the bottom plate 80 by a screw. The guide 114 guides the flame ejected from the pilot burner 112 toward the main burner 40.

[0034] 6, the ignition device 110 (i.e., the spark plug 111, the pilot burner 112, the holder 113, and the guide 114) is hidden under the bottom wall 11 of the drain pan 10 and is not located under the opening 12a. In other words, the ignition device 110 is disposed at a position horizontally offset from the opening 12a. Therefore, the ignition device 110 is not exposed from the opening 12a in a plan view.

[0035] <1-2.Effects> The drain pan 10 has an opening 12a for arranging the main burner 40. Oil from ingredients and cinders from ingredients fall through the opening 12a. If the pilot burner 112 for igniting the main burner 40 were arranged under the opening 12a of the drain pan 10, the pilot burner 112 may be contaminated by the oil from ingredients and cinders from ingredients. If the pilot burner 112 becomes contaminated, there is a risk of ignition failure of the pilot burner 112. Therefore, in the cooking device 1000 of the present invention, the pilot burner 112 is not arranged under the opening 12a of the drain pan 10. This makes it possible to prevent the oil from ingredients and cinders from ingredients that fall through the opening 12a from adhering to the pilot burner 112. As a result, the pilot burner 112 is less likely to be contaminated, and ignition failure of the pilot burner 112 can be prevented.

[0036] Spark plug 111 is not located below opening 12a of drain pan 10. This makes it possible to prevent oil from ingredients or burnt ingredients that fall through opening 12a from adhering to spark plug 111. As a result, spark plug 111 is less likely to become dirty and malfunction of spark plug 111 can be prevented.

[0037] The guide 114 is not positioned below the opening 12a of the drain pan 10. This makes it possible to prevent oil and burnt food ingredients that have fallen through the opening 12a from accumulating in the guide 114. In other words, since it is possible to prevent oil and burnt food ingredients from accumulating in the flow path of the flame ejected from the pilot burner 112, the flame ejected from the pilot burner 112 is reliably guided to the main burner 40.

[0038] The burner support member 90 is indirectly fixed to the bottom plate 80 via the drain pan support member 120. Two inclined surfaces 92a of the side wall 92 of the burner support member 90 are in contact with the inner surface of the inner peripheral wall 12 of the drain pan 10. In this manner, by supporting the drain pan 10 by the burner support member 90, which is immovable with respect to the bottom plate 80, rattling of the drain pan 10 can be prevented.

[0039] The cooking device 1000 includes a protective member 100. The protective member 100 can prevent an object present below the protective member 100 from being damaged by radiant heat. For example, in the case of a tabletop cooking device 1000, the top plate of a table T can be prevented from being burnt by radiant heat.

[0040] <2. Second embodiment> A cooking device 2000 according to the second embodiment will be described with reference to Fig. 7 and Fig. 8. The following mainly describes the differences between the cooking device 2000 according to the second embodiment and the cooking device 1000 according to the first embodiment. Among the components of the cooking device 2000 according to the second embodiment, the same components as those of the cooking device 1000 according to the first embodiment are denoted by the same reference numerals, and detailed descriptions of the structures and functions of the components will be omitted.

[0041] When using a net with a central region raised higher than the outer edge (see FIG. 2) as the cooking utensil 70, it is preferable to place the hot plate 60 at a higher position and bring it closer to the net in order to heat the central region of the net to a higher temperature. However, when using a flat net (i.e., a net with an outer edge and a central region located on the same plane), if the hot plate 60 is placed at a higher position, there is a risk that the hot plate 60 will come into contact with the central region of the flat net. Therefore, the second embodiment of the present invention aims to provide a cooking device 2000 configured so that the flat cooking utensil 70 does not interfere with the hot plate 60.

[0042] <2-1. Structure of cooking device> 8, the cooking device 2000 differs from the cooking device 1000 according to the first embodiment in that the cooking device 70 is flat (for example, a flat net) and further includes an attachment 130 for lifting the flat cooking device 70 upward. Other components of the cooking device 2000 are the same as those of the cooking device 1000.

[0043] As shown in FIG. 7, the attachment 130 includes a cylindrical support portion 131, a donut-shaped mounting portion 132, and a cylindrical restricting portion 133.

[0044] 8, the support portion 131 is placed on the step 13b of the drain pan 10. The upper end of the support portion 131 is located higher than the upper end of the hot plate 60.

[0045] The placement portion 132 is made of a doughnut-shaped flat plate. The cooking utensil 70 is placed on the placement portion 132. The placement portion 132 extends horizontally radially outward from the upper end of the support portion 131. The upper surface of the placement portion 132 is located above the upper end of the hot plate 60.

[0046] The restricting portion 133 restricts the horizontal movement of the cooking utensil 70. The restricting portion 133 extends upward from the outer edge of the placement portion 132 and is located outward from the outer edge of the cooking utensil 70. It is preferable that the restricting portion 133 surrounds the entire outer edge of the cooking utensil 70. In addition, it is preferable that the vertical length of the restricting portion 133 is greater than the thickness of the outer edge of the cooking utensil 70. In other words, it is preferable that the upper end of the restricting portion 133 is located above the upper end of the outer edge of the cooking utensil 70.

[0047] <2-2.Effects> By providing the attachment 130 to the cooking device 2000, the cooking utensil 70 can be placed at a higher position than when the attachment 130 is not used. This makes it possible to prevent the cooking utensil 70 from coming into contact with the hot plate 60 even if the cooking utensil 70 is flat.

[0048] The attachment 130 includes the restricting portion 133, which can prevent the cooking utensil 70 from shifting horizontally.

[0049] Since the restricting portion 133 surrounds the entire outer edge of the cooking utensil 70, it is possible to prevent a person eating from touching the hot cooking utensil 70 while the cooking device 2000 is in use.

[0050] Since the upper end of the restricting portion 133 is located above the upper end of the outer edge of the cooking utensil 70, a person eating the food can be prevented from touching the hot cooking utensil 70 while the cooking device 2000 is in use.

[0051] <3. Modifications> The present invention is not limited to the above embodiment, and various modifications are possible without departing from the scope of the present invention. Modifications of the present invention will be described below. The modifications described below can be applied to the above embodiment alone or in appropriate combination without departing from the scope of the present invention.

[0052] (3-1) The bottom plate 80 and the protective member 100 do not have to be separate members, and the bottom plate 80 may also function as the protective member 100.

[0053] (3-2) The burner support member 90 may be fixed directly to the bottom plate 80 instead of being fixed to the bottom plate 80 via the drain pan support member 120 .

[0054] (3-3) When the cooking appliances 1000, 2000 are tabletop types, it is preferable that the cooking appliances 1000, 2000 are provided with the protective member 100. However, when the cooking appliances 1000, 2000 are built-in types, the cooking appliances 1000, 2000 do not necessarily have to be provided with the protective member 100.

[0055] (3-4) In the above, an embodiment has been described in which the inclined surface 92a of the side wall 92 of the burner support member 90 contacts the inner circumferential wall 12 of the drain pan 10. However, the cooking appliances 1000, 2000 may further include a rattle suppression member 140 formed as a separate member from the burner support member 90, and a part of the rattle suppression member 140 may contact the inner surface of the inner circumferential wall 12 instead of the inclined surface 92a of the burner support member 90, as shown in FIG.

[0056] As shown in FIG. 10 and FIG. 11, the rattle suppression member 140 is disposed on the burner support member 90. The rattle suppression member 140 includes an upper wall 141 and a side wall 142 extending downward from the upper wall 141. The upper wall 141 has an opening for passing the main burner 40. The upper wall 141 is fixed to the upper wall 91 by being sandwiched between the upper wall 91 and the main burner 40. As already described, the burner support member 90 is fixed to the bottom plate 80 via the drain pan support member 120, so that the rattle suppression member 140 fixed to the burner support member 90 is immovable relative to the bottom plate 80. The side wall 142 is located outside the side wall 92 of the burner support member 90. The width of the side wall 142 is larger than the width of the side wall 92. Both end faces in the width direction of the side wall 142 are inclined surfaces 142a that are inclined so as to widen outward as they go downward. The sidewall 142 is disposed at a position horizontally offset from the center of the opening 12a of the drain pan 10. As shown in Fig. 11, the upper portion of the rattle suppression member 140 (the upper portion of the sidewall 142 and the upper wall 141) is inserted into the opening 12a. The two inclined surfaces 142a of the sidewall 142 are in contact with the inner surface of the inner circumferential wall 12 of the drain pan 10. It is preferable that the inclination angle of the inclined surfaces 142a is the same as or close to the inclination angle of the inner circumferential wall 12.

[0057] The rattle suppression member 140 may be fixed directly to the bottom plate 80 instead of being fixed to the bottom plate 80 via the burner support member 90 and the drain pan support member 120 .
