Description

[Technical field]

[0001] The present invention relates to a top plate and a cooking device including the top plate. [Background technology]

[0002] Patent Document 1 describes a conventional top plate (called a tabletop in Patent Document 1). The tabletop described in Patent Document 1 is composed of a lower plate, an upper plate, and a frame. The frame uses four straight frames with a U-shaped cross section to sandwich the upper plate and the lower plate at the four outer edges of the plates. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-360984 A Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, the frame of a top plate is one of the important design elements since it is exposed to the outside. For this reason, in the tabletop described in Patent Document 1, it is necessary to make the straight line frames corresponding to each side into one continuous straight line frame.

[0005] When the upper and lower plates are sandwiched together, the upper and lower pieces, which have a U-shaped cross section, must be elastically spread apart, but the tabletop described in Patent Document 1 requires the use of a long straight frame, making it difficult to spread the upper and lower pieces. In other words, the tabletop described in Patent Document 1 is difficult to assemble.

[0006] It is also possible to prioritize ease of assembly during manufacturing and design the distance between the upper and lower pieces of the frame body to be larger than the thickness of the upper and lower plates; however, in this case, the upper and lower plates cannot be fixed with an appropriate fixing strength.

[0007] In short, the tabletop described in Patent Document 1 has the problem that the upper and lower plates are fixed to each other by a frame, which makes it difficult to assemble and makes it impossible to properly fix the upper and lower plates.

[0008] The present invention has been made in consideration of the above circumstances, and aims to provide a top plate and a cooking appliance equipped with the same that can fix the surface layer and the back layer with appropriate fixing strength without compromising ease of assembly. [Means for solving the problem]

[0009] A top plate according to one aspect of the present invention is a top plate for use in a cooking device, and includes a plate body formed in a plate shape and a frame body surrounding the outer periphery of the plate body. The plate body includes a surface layer including an upper surface of the plate body, a back layer body overlapping a lower surface of the surface layer body, and a fixing member housed in the frame body and fixing an outer peripheral end of the surface layer body and an outer peripheral end of the back layer body to each other.

[0010] A cooking device according to one aspect of the present invention includes a device body and the top plate attached to the device body. Effect of the Invention

[0011] The top plate of the above aspect according to the present invention and the cooking device including the same have the advantage that the surface layer and the back layer can be fixed with an appropriate fixing strength without impairing the ease of assembly.

[0013] <Embodiment> The top plate 3 and the cooking appliance 1 according to this embodiment will be described in detail below.

[0014] (1) Overall The cooking device 1 is a cooking appliance that cooks food using a heat source such as gas or electricity. Examples of the cooking device 1 include a gas stove, an electromagnetic cooker (IH (Induction Heating) cooker), and an electric stove. The cooking device 1 according to this embodiment is a gas stove with a grill, as shown in FIG. 1.

[0015] A gas stove is a stove that uses gas as fuel. The gas stove according to this embodiment is a built-in stove in which the device body 2 is dropped into an opening formed in the worktop of a kitchen counter, but it may also be a table stove that is used by placing it on an installation surface (for example, a table, a stove stand, etc.).

[0016] Furthermore, although the gas stove according to this embodiment has the grill section 23, the present invention does not necessarily require the grill section 23. Furthermore, instead of the grill section 23, for example, a multi-grill having a range function, an oven function and a rice cooking function may be provided, or any one of a range, an oven or a rice cooker may be provided.

[0017] For ease of explanation, the following directions are defined based on the manner in which the gas stove is used. In other words, assuming a manner in which the user cooks while facing the gas stove, the "left-right direction" is defined as shown in FIG. 1. The direction from the gas stove toward the user and along the horizontal plane is defined as the "front direction," the opposite direction is defined as the "rear direction," and the two directions parallel to the front and rear directions are defined as the "front-rear direction." The direction perpendicular to the installation surface is defined as the "up-down direction." However, these definitions of directions are not intended to limit the manner in which the cooking device 1 according to the present invention is used.

[0018] As shown in FIG. 1, the cooking device 1 includes a device main body 2 and a top plate 3 to which a plurality of (three in this example) trivets 9 are removably attached.

[0019] (2) Device body The device body 2 constitutes the main body of the cooking device 1. The device body 2 includes a housing 21 and a plurality of devices 22, 23. The device body 2 according to the present embodiment includes a grill section 23 and a plurality of heating sections 22 as the plurality of devices 22, 23.

[0020] (2.1) Housing The housing 21 is a box in the device body 2 that houses the devices. The housing 21 is formed in a rectangular parallelepiped shape and has an opening (not shown) on the top surface. As shown in Fig. 1, the front surface of the housing 21 is formed with an opening 211 for passing through the grill door 231 of the grill section 23, and an opening 212 for passing through the operating device 24 that ignites / extinguishes the fire and adjusts the flame power of each device.

[0021] (2.2) Heating section The heating unit 22 heats the food placed above the top plate 3. Here, "food placed above the top plate 3" refers to, for example, food contained in a cooking utensil such as a pot or frying pan, water (including hot water), etc. The heating unit 22 may be an IH heater that heats the food by generating heat from the cooking utensil without applying heat itself, but in this embodiment, the heating unit 22 is configured by a burner 221 that heats the food by heating the cooking utensil placed on the trivet 9. The burner 221 is a Bunsen burner that receives a supply of gas containing gas and performs premixed combustion.

[0022] The burners 221 are arranged apart from one another within the housing 21. Ignition / extinguishing and flame power adjustment for the burners 221 are controlled by an operating device 24 (for example, an operating dial, an operating knob, an operating lever, etc.) passed through an opening 212 on the front surface of the housing 21.

[0023] (2.3) Grill section Grill section 23 can grill food stored in a grill chamber (not shown). Grill section 23 includes a grill chamber (not shown) having an opening on the front side, and a grill door 231 that opens and closes the opening of the grill chamber. Grill door 231 is attached via a support mechanism (not shown) so as to be movable in parallel along the front-rear direction relative to the grill chamber.

[0024] (3) Top plate The top plate 3 is the uppermost plate of the cooking appliance 1. As shown in Fig. 2, the top plate 3 is formed in a substantially rectangular plate shape. The top plate 3 is formed with a plurality of (three in this case) holes (referred to as "burner insertion holes 45") through which the upper ends of the burners 221 pass, and the top plate 3 is attached to the housing 21 of the device main body 2 so as to rest on the upper end of the housing 21. As shown in Fig. 2, the top plate 3 includes a plate main body 4 and a frame 8.

[0025] (3.1) Plate body The plate body 4 is a part that constitutes the main body of the top plate 3. The plate body 4 is formed in a plate shape and is formed in a rectangular shape in a plan view. As shown in Fig. 3, the plate body 4 includes a surface layer 5, a back layer 6, a plurality of fixing members 7, a reinforcing plate 42, a plurality of burner rings 43, and a plurality of connecting plates 44.

[0026] (3.1.1) Surface body The surface layer 5 is a portion including the upper surface of the plate body 4. The surface layer 5 is formed in a generally rectangular shape in a plan view. Examples of the surface layer 5 include a transparent plate, a transparent sheet, and a transparent film. The term "transparent" as used herein means that the surface layer 5 has a transmittance that allows the color or pattern of the back layer 6 to be seen through the surface layer 5. In this embodiment, for example, a material with a transmittance of 5% or more is "transparent," and so-called semi-transparent materials are also included in the category of "transparent." A transparent plate 51 is used as the surface layer 5 according to this embodiment. Examples of the transparent plate 51 include a glass plate and a heat-resistant resin plate, and a glass plate is preferable from the viewpoint of heat resistance and design.

[0027] The surface layer 5 has a plurality of openings 52 formed at positions corresponding to the burner insertion holes 45. Each opening 52 penetrates the surface layer 5.

[0028] (3.1.2) Lining The back layer 6 is a portion that overlaps the lower surface of the front layer 5. The back layer 6 is formed in a generally rectangular shape in a plan view, and is formed to be approximately the same shape and size as the front layer 5. Therefore, the outer peripheral edge of the back layer 6 is located at a position that is approximately aligned with the outer peripheral edge of the front layer 5 in a plan view, and the end face of the back layer 6 and the end face of the upper layer are flush with each other and face to the side.

[0029] The back layer 6 is made of a material different from that of the front layer 5. The back layer 6 is not particularly limited in terms of rigidity and thickness, and may be, for example, a plate, a sheet, a film, etc. The back layer 6 according to this embodiment is a plate material. The back layer 6 may also be, for example, a decorative material that can improve the design visible through the front layer 5, or a reinforcing material that reinforces the front layer 5. Here, a decorative board 61 will be used as an example of the back layer 6.

[0030] The decorative plate 61 is a plate material having a decorative surface at least on the upper surface. The decorative plate 61 is formed in a flat plate shape. The material of the decorative plate 61 is not particularly limited, and examples thereof include metal, synthetic resin, FRP (Fiberglass Reinforced Plastics), carbon, and wood board. Examples of metals include steel, stainless steel, titanium, gold, silver, copper, platinum, and aluminum. The decorative plate 61 according to this embodiment is made of a metal plate made of a color steel plate.

[0031] The decorative surface is not particularly limited, and may be composed of a single color, may be composed of multiple colors (e.g., gradation, stripes, etc.), or may have a pattern such as a checkered pattern, polka dots, or floral pattern. The color or pattern of the decorative surface is formed by, for example, painting, printing, vapor deposition, plating, etc. Also, the surface of gold, silver, copper, etc. may be used as it is as the decorative surface. Also, a part of the upper surface of the decorative plate 61 may be the decorative surface.

[0032] The back layer 6 has a plurality of openings 62 formed at positions corresponding to the burner insertion holes 45. Each opening 62 penetrates the back layer 6. The plurality of openings 62 of the back layer 6 are formed at positions that coincide with the plurality of openings 62 of the front layer 5 in a plan view, and communicate with each other.

[0033] (3.1.3) Fixing members The fixing member 7 is a member for fixing the outer peripheral end of the front layer 5 and the outer peripheral end of the back layer 6 to each other. As shown in FIG. 3, the fixing member 7 includes a plurality of (four in this case) first fixing plates 71 and a second fixing plate 72.

[0034] The first fixing plate 71 fixes the corners of the front layer 5 and the back layer 6 together when they are stacked. Here, "corner" means a protruding corner formed by either edge in the left-right direction and either edge in the front-rear direction. One first fixing plate 71 can fix one edge in the left-right direction constituting one corner of the front layer 5 and the back layer 6 together, and one edge in the front-rear direction constituting the corner.

[0035] 4(A)(B), the first fixing plate 71 includes a horizontal plate portion 711, an upright plate portion 712, and a connecting portion 714. The first fixing plate 71 includes the horizontal plate portion 711, the upright plate portion 712, and the connecting portion 714, which are integrally formed by, for example, press working. In this embodiment, the first fixing plate 71 is made of a metal plate, but is not limited thereto as long as it can fix the front layer 5 and the back layer 6 to each other, and may be made of, for example, a synthetic resin plate, a wood plate, or the like. Examples of the metal plate include steel, stainless steel, aluminum, and titanium.

[0036] The horizontal plate portion 711 is a portion formed in a plate shape along the lower surface of the back layer 6. In this embodiment, the horizontal plate portion 711 is formed in a substantially L-shape, but is not limited thereto, and may be formed in, for example, a substantially C-shape, a sector shape, a triangular shape, a rectangular shape, etc. The horizontal plate portion 711 is preferably fixed to the lower surface of the back layer 6 by adhesion, but does not necessarily have to be adhered.

[0037] The standing plate portion 712 is a portion that is raised from the end portion of the horizontal plate portion 711 along the outer edge of the surface layer 5 and the back layer 6. The standing plate portion 712 spans the end face of the back layer 6 and the end face of the surface layer 5. Here, "spanning the end face of the back layer 6 and the end face of the surface layer 5" means that the standing plate portion 712 extends from the lower end of the end face of the back layer 6 to a position that covers at least a part of the end face of the surface layer 5. Therefore, the standing plate portion 712 does not necessarily need to cover the entire end face of the surface layer 5 and the end face of the back layer 6.

[0038] 5(A), an adhesive B1 is interposed between the standing plate portion 712 and the end surface of the front layer 5 and the end surface of the back layer 6, thereby fixing the standing plate portion 712 to the end surface of the front layer 5 and the end surface of the back layer 6. There is no particular limitation on the adhesive B1, and examples of the adhesive include natural adhesives, thermoplastic resin adhesives, thermosetting resin adhesives, and elastomer adhesives. Examples of the elastomer adhesives include silicone resin adhesives, acrylic rubber adhesives, urethane rubber adhesives, and modified silicone rubber adhesives, and in this embodiment, a silicone resin adhesive is used.

[0039] A plurality of through holes 713 are formed in the standing plate portion 712. As shown in FIG. 5(A), the through holes 713 are formed at a position above the upper surface of the back layer 6 (i.e., the boundary between the back layer 6 and the front layer 5). This allows the through holes 713 to discharge excess adhesive B1 between the standing plate portion 712 and the end surface of the front layer 5 and the end surface of the back layer 6. Therefore, even if the fixing member 7 is pressed against the back layer 6 and the front layer 5 during manufacturing, when the back layer 6 and the front layer 5 are bonded with adhesive B1, the adhesive B1 is discharged through the through holes 713, so that the adhesive B1 is prevented from penetrating between the back layer 6 and the front layer 5.

[0040] In addition, since the through hole 713 is formed at a position above the upper surface of the lining layer 6, the adhesive area at the interface between the surface layer 5 and the lining layer 6 with respect to the standing plate portion 712 is not reduced. Therefore, it is possible to prevent the fixing strength between the lining layer 6 and the surface layer 5 from decreasing. Here, "formed at a position above the upper surface of the lining layer 6" in this specification means that the lower end of the through hole 713 is at the same height as the upper surface of the lining layer 6 or higher. However, from the viewpoint of improving the fixing strength between the surface layer 5 and the lining layer 6, it is preferable that the lower end of the through hole 713 is higher than the upper surface of the lining layer 6.

[0041] As shown in Figs. 4(A) and (B), the multiple through holes 713 are formed at regular intervals in a direction perpendicular to the standing direction of the standing plate portion 712 (direction along the end face of the plate body 4). Each through hole 713 is set to a diameter that prevents the adhesive B1 from passing when the pressure applied from the adhesive B1 to the standing plate portion 712 is less than a certain pressure, but allows the adhesive B1 to pass when the pressure is equal to or greater than the certain pressure. The diameter of each through hole 713 is preferably 1 mm or more and 3 mm or less, and more preferably 1.5 mm or more and 2.5 mm or less. However, the diameter of the through hole 713 is set to an appropriate value depending on the viscosity of the adhesive. Each through hole 713 is circular, but may be, for example, rectangular, elliptical, or slit-shaped.

[0042] The connecting portion 714 is provided on the horizontal plate portion 711. The connecting portion 714 protrudes downward from the horizontal plate portion 711, and has a locking hole 715 that can be hooked onto the claw portion 213 of the device body 2. FIG. 6 shows a cross-sectional view of a state in which the upper end portion of the housing 21 of the device body 2 and the fixing member 7 of the top plate 3 are connected. The upper end portion of the housing 21 is provided with the claw portion 213 made of a leaf spring. When the top plate 3 is placed on the upper surface of the housing 21, the connecting portion 714 pushes the claw portion 213 outward and moves downward. Then, the claw portion 213 is restored by elastic force and enters the locking hole 715. As a result, the top plate 3 is attached to the device body 2.

[0043] 3, the connecting portion 714 is formed on all four fixing members 7, but only the front two are bent and used, and the rear two are not used. Therefore, the rear two fixing members 7 are not bent with respect to the horizontal plate portion 711.

[0044] The second fixing plate 72 fixes the portion between the adjacent corners (here, only the front side) when the surface layer 5 and the back layer 6 are stacked. The second fixing plate 72 is used appropriately according to the dimension between the corners of the top plate 3. For example, representative examples of the left-right dimension of the top plate 3 are 650 mm and 750 mm. When the dimension is 650 mm, the second fixing plate 72 is not necessary, but when the dimension is 750 mm, it is preferable to provide the second fixing plate 72. This is because, when the dimension between the adjacent first fixing plates 71 is long, the fixing strength between the surface layer 5 and the back layer 6 may be insufficient without the second fixing plate 72.

[0045] 7, the second fixing plate 72 includes a horizontal plate portion 721 and an upright plate portion 722. The horizontal plate portion 721 is a portion formed in a plate shape along the lower surface of the backing layer 6. The horizontal plate portion 721 is formed in a substantially rectangular shape, but there is no limitation on the shape. In addition, the horizontal plate portion 721 is preferably fixed to the lower surface of the backing layer 6 by adhesion, but does not necessarily have to be adhered.

[0046] The standing plate portion 722 is a portion that rises from the end portion of the horizontal plate portion 721 along the outer edges of the surface layer 5 and the back layer 6. Like the first fixing plate 71, the standing plate portion 722 spans the end face of the back layer 6 and the end face of the surface layer 5. Like the first fixing plate 71, the standing plate portion 722 has adhesive B1 interposed between the end face of the surface layer 5 and the end face of the back layer 6, thereby fixing the end face of the surface layer 5 and the end face of the back layer 6 to each other.

[0047] A plurality of through holes 723 are formed in the standing plate portion 722. The through holes 723 are formed at a position above the upper surface of the back layer 6, similar to the first fixing plate 71. This allows the through holes 723 to discharge excess adhesive B1 between the standing plate portion 722 and the end surface of the front layer 5 and the end surface of the back layer 6.

[0048] The first fixing plate 71 and the second fixing plate 72 (i.e., the fixing member 7) are housed within a frame body 8 as shown in Fig. 5(A). "Housed within the frame body 8" means that the fixing member 7 is disposed within an area inside the outer periphery of the frame body 8. The fixing member 7 according to this embodiment is housed within the frame body 8, and the upright plate portions 712, 722 are covered by the frame body 8 and the horizontal plate portions 711, 721 are covered by the top plate 3. Therefore, the fixing member 7 is not exposed when viewed from above and the appearance is not impaired.

[0049] As shown in FIG. 3, the top plate 3 according to this embodiment includes a pressing member 41 that sandwiches the rear end of the back layer 6 together with the frame 8. As shown in FIG. 5(B), the pressing member 41 includes a pressing portion 411 that fits along the lower surface of the back layer 6, a rising portion 412 that protrudes upward from the pressing portion 411, and a rib portion 413 that is folded back from the rising portion 412 and extends downward. The pressing portion 411 and the back layer 6 are bonded together with the adhesive B1, and the rising portion 412 and the frame 8 are bonded together with the adhesive B1, so that the rear end of the back layer 6 is pressed against the surface layer 5. The pressing member 41 may be attached as necessary.

[0050] (3.1.4) Reinforcement plate The reinforcing plate 42 is a reinforcing plate that overlaps the lower surface of the back layer 6. As shown in Fig. 3, the reinforcing plate 42 is formed in a substantially triangular shape in a plan view, and has a plurality of openings 421 formed at positions corresponding to the burner insertion holes 45. Each opening 421 is formed corresponding to the opening 52 of the front layer 5 and the opening 62 of the back layer 6, and is formed at a position that coincides in a plan view.

[0051] The material of the reinforcing plate 42 is not particularly limited, and examples thereof include metal, synthetic resin, FRP (Fiberglass Reinforced Plastics), carbon, wood board, etc. The reinforcing plate 42 according to this embodiment is made of a metal plate.

[0052] (3.1.5) Burner ring, connecting plate The burner ring 43 constitutes a burner insertion hole 45 in the top plate 3. Each burner ring 43 is formed in a circular ring shape in a plan view. The burner ring 43 is composed of a flange 431 facing the upper surface of the surface layer 5 and a cylindrical body 432 protruding downward from the inner peripheral surface of the flange 431. With the cylindrical body 432 inserted into the O-ring 433, the cylindrical body 432 is inserted from above into the openings 52, 62 formed in the surface layer 5 and the back layer 6, and the opening 421 of the reinforcing plate 42. Then, a connecting plate 44 is fixed to the lower end of the cylindrical body 432.

[0053] The connecting plate 44 is attached to the lower end of the cylindrical body 432 of the burner ring 43 and fixed to the reinforcing plate 42. This prevents the burner ring 43 from rotating around the center of the burner insertion hole 45, and allows the flange 431 of the burner ring 43 to be pressed against the upper surface of the surface body 5, ensuring watertightness between the upper surface of the surface body 5 and the burner ring 43. The connecting plate 44 is formed in a disk shape, but there is no particular limitation on the shape.

[0054] (3.2) Frame The frame 8 surrounds the outer periphery of the plate body 4. As shown in Fig. 3, the frame 8 includes a frame-shaped portion 81, an exhaust portion 82 provided integrally on the rear side of the frame-shaped portion 81, and a side wall portion 83. The frame 8 is integrally formed by pressing a metal plate. There are no particular limitations on the metal plate, and examples of the metal plate include steel, stainless steel, titanium, and aluminum.

[0055] The frame-shaped portion 81 is formed along the outer periphery of the plate body 4 and covers the upper surface of the outer periphery end portion of the plate body 4. The frame-shaped portion 81 is formed in a rectangular frame shape. As shown in FIG. 5(A), the frame-shaped portion 81 includes an abutment portion 811 and a proximity portion 812.

[0056] The adjacent portion 812 covers the outer peripheral end of the plate body 4 with a gap therebetween. The adjacent portion 812 is formed along a horizontal plane. The space between the adjacent portion 812 and the outer peripheral end of the plate body 4 is filled with adhesive B1.

[0057] The abutment portion 811 is provided on the inner peripheral end of the proximal portion 812 and abuts against the upper surface of the surface body 5. In other words, the abutment portion 811 constitutes the inner peripheral end of the frame-shaped portion 81. The abutment portion 811 is formed in a substantially L-shaped cross section, and its lower end face abuts against the upper surface of the surface body 5. By providing the abutment portion 811, the frame-shaped portion 81 can prevent moisture adhering to the upper surface of the plate body 4 from penetrating to the outside of the top plate 3 and between the frame body 8 and the plate body 4.

[0058] The exhaust section 82 is a portion in which an exhaust port 821 for exhausting air from inside the grill chamber is formed. As shown in Fig. 3, the exhaust section 82 is provided at the rear of the frame-shaped section 81. As shown in Fig. 1, an exhaust port cover 822 is removably attached to the exhaust port 821.

[0059] 3, the side wall portion 83 is a portion that surrounds the outer periphery of the frame 8. The lower end of the side wall portion 83 is disposed so as to face the upper surface of the worktop, and the side wall portion 83 covers the end surface of the top plate 3 from the side.

[0060] (4) Manufacturing method Next, an example of a method for manufacturing the top plate 3 according to this embodiment will be described.

[0061] First, a glass plate as the front layer 5, a color steel plate as the back layer 6, and a reinforcing plate 42 are stacked, and these are sandwiched between a plurality of burner rings 43 and connecting plates 44 (hereinafter, this is referred to as the "plate set 4S"). Next, as shown in Fig. 8, the frame 8 is turned upside down, and adhesive B1 (here, a silicone resin adhesive) is applied over the entire length to the back surface of the adjacent portion 812 of the frame 8 (i.e., the lower surface in the installed state).

[0062] 9, the plate set item 4S is placed upside down on the frame body 8 which is also upside down, and the frame body 8 and the plate set item 4S are bonded together. Next, adhesive B1 is applied along the standing plate portion 712 of the first fixing plate 71 and the standing plate portion 722 of the second fixing plate 72, and the first fixing plate 71 and the second fixing plate 72 are placed on the plate set item 4S and pressed in with an appropriate force.

[0063] Then, adhesive B1 is filled between the end faces of the glass plate and the end faces of the color steel plate and the standing plate portions 712, 722, but as shown in Fig. 5(A), excess adhesive B1 is discharged through the through holes 713, 723. Therefore, even if the standing plate portions 712, 722 pressurize the adhesive B1, it is possible to prevent the adhesive B1 from getting between the glass plate and the color steel plate.

[0064] 9, adhesive B1 is applied to the pressing portion 411 of the pressing member 41, the pressing portion 411 is pressed against the plate set 4S, and the rising portion 412 is pressed against the frame 8. At this time, adhesive B1 is also interposed between the rising portion 412 and the frame 8. In this state, the adhesive B1 is waited for to harden, and the top plate 3 is completed as shown in FIG.

[0065] In this way, in the top plate 3 according to this embodiment, the outer peripheral end of the surface layer 5 and the outer peripheral end of the back layer 6 are fixed to each other by the fixing member 7 that is separate from the frame 8, so that the surface layer 5 and the back layer 6 are made of different materials, but the ease of assembly can be improved. This makes it possible to reduce costs by making the transparent plate 51 and the decorative plate 61 out of different materials without using a conventional manufacturing method such as printing on the back surface of a glass plate, while still maintaining ease of assembly.

[0066] <Modification> The above embodiment is merely one of various embodiments of the present invention. The embodiment can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved. The modified examples described below can be applied in appropriate combination.

[0067] (1) Variation 1 The fixing member 7 according to the above embodiment fixes the outer peripheral end of the front layer 5 and the outer peripheral end of the back layer 6 by adhesion, but the fixing member 7 according to the first modification fixes the outer peripheral end of the front layer 5 and the outer peripheral end of the back layer 6 by sandwiching them together, as shown in Fig. 11. The other configurations are the same as those of the above embodiment, and therefore will not be described here.

[0068] As shown in Fig. 11, the fixing member 7 includes an upper piece 73, a lower piece 74, and a connecting piece 75 that connects the base end of the upper piece 73 with the base end of the lower piece 74. The fixing member 7 is preferably made of a material that has a certain rigidity and is elastically deformable. Examples of materials for the fixing member 7 include leaf springs, wire springs, and synthetic resins. Examples of leaf springs that can be used include stainless steel, carbon steel, and copper phosphate.

[0069] The upper piece 73 faces the upper surface of the surface body 5 and is in contact with said upper surface. As shown in Fig. 12, the upper piece 73 is formed so as to have the same protruding dimension over its entire length in a direction (sometimes referred to as the "width direction") perpendicular to the direction from the base end toward the tip (sometimes referred to as the "protruding direction"). The "protruding dimension" here means the dimension from the base end to the tip.

[0070] The lower piece 74 faces the lower surface of the lining layer 6. The lower piece 74 is formed with a longer protruding dimension than the upper piece 73. The lower piece 74 is composed of a clamping piece 741 that contacts the lower surface of the lining layer 6, and an introduction piece 742 provided at the tip of the clamping piece 741. The protruding dimension of the clamping piece 741 is formed slightly shorter than the protruding dimension of the upper piece 73 as shown in FIG. 11, but may be the same dimension or greater.

[0071] The introduction piece 742 is formed at the tip of the lower piece 74. The introduction piece 742 is inclined with respect to the lower surface of the back layer 6 so as to move downward as it moves away from the connection piece 75. The introduction piece 742 makes it easier to fit the outer peripheral end of the front layer 5 and the outer peripheral end of the back layer 6 into the fixing member 7.

[0072] The multiple fixing members 7 are housed within a frame 8 as shown in Fig. 11. The upper piece 73 is disposed between the upper surface of the front layer 5 and the adjacent portion 812, and is not exposed from the outside. The multiple fixing members 7 partially sandwich the front layer 5 and the back layer 6 at the positions indicated by the dashed circles (a total of eight positions), as shown in Fig. 13. It is preferable that the distance between adjacent fixing members 7 is set to a dimension that prevents the back layer 6 from sagging between the fixing members 7.

[0073] In Figure 13, the front first fixing plate 71 (here, "fixing plate 71A") of the first fixing plates 71 used in the above embodiment is attached, but it does not have the function of adhering the front layer 5 and the back layer 6, and is adhered only to the back layer 6 and has the function of connecting to the device main body 2.

[0074] (2) Variation 2 In the fixing member 7 of the above-mentioned variant example 1, the upper piece 73 and the lower piece 74 have the same protruding dimension in the width direction. However, as shown in FIG. 14, the protruding dimension of the upper piece 73 and the lower piece 74 may vary along the width direction.

[0075] Here, as shown in FIG. 14, in the fixing member 7, one end in the width direction is defined as a "first end X1" and the other end in the width direction is defined as a "second end X2".

[0076] In the width direction of the upper piece 73, a first portion 76 having the same protruding dimension and a second portion 77 having a varying protruding dimension are adjacent to each other and continuous along the direction from the first end X1 to the second end X2. The second portion 77 is formed so that the protruding dimension becomes shorter along the direction from the first end X1 to the second end X2.

[0077] In the width direction of the lower piece 74, a first portion 76 having the same protruding dimension and a second portion 77 having a varying protruding dimension are adjacent to each other and continuous along the direction from the second end X2 to the first end X1. The second portion 77 is formed so that the protruding dimension becomes shorter along the direction from the second end X2 to the first end X1.

[0078] The fixing member 7 is configured such that the edges of the tips of the second portions 77 intersect in a plan view. Therefore, the upper and lower pieces 73 and 74 of the fixing member 7 are inclined so that the width direction is inclined relative to the horizontal plane, and the upper and lower pieces 73 and 74 of the fixing member 7 are pressed against the outer peripheral end of the front layer 5 and the outer peripheral end of the back layer 6, and the upper and lower pieces 73 and 74 are changed in orientation so as to approach the horizontal plane, so that the upper and lower pieces 73 and 74 can be easily elastically deformed. Therefore, according to the fixing member 7 of the second modification, even without the introduction piece 742, the fixing member 7 can be easily attached to the front layer 5 and the back layer 6. In addition, the fixing member 7 of the second modification is formed in a shape that is point-symmetrical with respect to the normal line passing through the center of the connection piece 75, and therefore has the advantage that it can be attached without worrying about the up and down orientation.

[0079] The "first end X1" may be the second end X2, and the "second end X2" may be the first end X1. Furthermore, the upper piece 73 and the lower piece 74 may be composed of only the second portion 77 over the entire width direction.

[0080] (3) Other modifications Modifications of the embodiment are listed below.

[0081] In the top plate 3 according to the above embodiment, the surface layer 5 is constituted by a transparent plate 51, but in the present invention, the surface layer 5 does not have to be transparent and may be constituted by a metal plate. Examples of the metal plate include aluminum, enamel, and fluorine-coated steel plate.

[0082] In addition, when the surface layer 5 is made of a flexible or pliable material, the back layer 6 may be made of a highly rigid material. Also, the surface layer 5 may be made of an expensive and thin material, and the back layer 6 may be made of an inexpensive and highly rigid material (i.e., a reinforcing material).

[0083] The fixing member 7 in the above-mentioned modified examples 1 and 2 is formed to have a substantially U-shaped cross section, but may be formed to have an H-shaped cross section, for example, and there is no particular limitation on the shape.

[0084] The first fixing plate 71 according to the above embodiment is fixed at both the left-right edge and the adjacent front-rear edge as corners of the front layer 5 and the back layer 6, but only one of the left-right edge and the front-rear edge may be fixed. Also, the second fixing plate 72 may be used instead of all the first fixing plates 71, the second fixing plate 72 may be used instead of the two rear first fixing plates 71 of the first fixing plates 71, or the second fixing plate 72 may be used instead of the two front first fixing plates 71 of the first fixing plates 71.

[0085] In this specification, expressions accompanied by "approximately", such as "approximately parallel" or "approximately perpendicular", may be used. For example, "approximately parallel" means that the state is substantially "parallel", and includes not only a strictly "parallel" state but also an error of a few degrees. The same applies to other expressions accompanied by "approximately".

[0086] Furthermore, in this specification, expressions that are distinguished by the presence or absence of "part", such as "end" and "end", are used. For example, "end" means the end part of an object, while "end" means a region having a certain range that includes the "end". Any point that is within a certain range that includes the end is considered to be an "end". The same applies to other expressions that include "part".

[0087] <Summary> As described above, the top plate 3 according to the first embodiment is a top plate 3 used in a cooking device 1. The top plate 3 includes a plate body 4 formed in a plate shape, and a frame body 8 surrounding the outer periphery of the plate body 4. The plate body 4 includes a surface layer 5 including an upper surface of the plate body 4, a back layer 6 overlapping a lower surface of the surface layer 5, and a fixing member 7 housed in the frame body 8 and fixing an outer peripheral end of the surface layer 5 and an outer peripheral end of the back layer 6 to each other.

[0088] According to this embodiment, the surface layer 5 and the back layer 6 can be fixed with the fixing member 7 and then attached within the frame body 8, so that the surface layer 5 and the back layer 6 can be fixed with appropriate fixing strength without compromising assembly ease.

[0089] In the top plate 3 according to the second embodiment, the surface layer 5 is a transparent plate 51 and the back layer 6 is a decorative plate 61 in the first embodiment.

[0090] According to this embodiment, there is no need to perform printing or the like on the back surface of the transparent plate 51. Therefore, by using the back layer 6 which is cheaper than the printing cost, it is easy to achieve cost reduction.

[0091] In the top plate 3 according to the third embodiment, in the first or second embodiment, the fixing member 7 has horizontal plate parts 711, 721 that run along the lower surface of the back layer 6, and standing plate parts 712, 722 that rise from the ends of the horizontal plate parts 711, 721 and span the end faces of the back layer 6 and the surface layer 5. The end faces of the back layer 6 and the surface layer 5 are bonded to the standing plate parts 712, 722, so that the outer peripheral end of the surface layer 5 and the outer peripheral end of the back layer 6 are fixed to each other.

[0092] According to this embodiment, the surface layer 5 and the back layer 6 can be bonded using the fixing member 7 after being arranged in an appropriate positional relationship, which makes assembly easier than when adhesive B1 is interposed between the back layer 6 and the surface layer 5. Furthermore, when the surface layer 5 is a transparent plate 51, interposing adhesive B1 between the back layer 6 and the surface layer 5 would cause the adhesive B1 to be visible through the surface layer 5, impairing the appearance, but this can be prevented according to this embodiment.

[0093] In the top plate 3 of the fourth aspect, in the third aspect, the upright plate portions 712, 722 have a plurality of through holes 713, 723 for discharging excess adhesive B1 between the upright plate portions 712, 722 and the end faces of the front layer 5 and the back layer 6.

[0094] According to this embodiment, even if the standing plate portions 712, 722 pressurize the adhesive B1 during bonding, excess adhesive B1 is discharged through the through holes 713, 723, thereby preventing the adhesive B1 from entering between the front layer 5 and the back layer 6.

[0095] In the top plate 3 according to the fifth embodiment, in the fourth embodiment, the plurality of through holes 713, 723 are formed in the upright plate portions 712, 722 at positions above the upper surface of the back layer 6.

[0096] According to this embodiment, the adhesion area at the boundary between the surface layer 5 and the back layer 6 can be made as large as possible, and the fixing strength between the surface layer 5 and the back layer 6 can be prevented from decreasing.

[0097] In the top plate 3 according to the sixth aspect, in any one of the first to fifth aspects, the fixing member 7 has a connecting portion 714 that is connected to the device body 2 of the cooking appliance 1.

[0098] According to this embodiment, one fixing member 7 can serve both the function of fixing the front layer 5 and the back layer 6 together and the function of attaching the top plate 3 to the device body 2, thereby reducing the number of parts.

[0099] In the top plate 3 according to the seventh aspect, in the first or second aspect, the fixing member 7 has an upper piece 73 facing the upper surface of the surface layer 5, a lower piece 74 facing the lower surface of the back layer 6, and a connecting piece 75 connecting the base end of the upper piece 73 to the base end of the lower piece 74. The back layer 6 and the surface layer 5 are sandwiched between the upper piece 73 and the lower piece 74, so that the outer peripheral end of the surface layer 5 and the outer peripheral end of the back layer 6 are fixed to each other.

[0100] According to this embodiment, since it is not necessary to use the adhesive B1 to fix the front layer 5 and the back layer 6, the overall amount of adhesive B1 used can be reduced.

[0101] In the top plate 3 according to the eighth aspect, the lower piece 74 is formed so that the dimension from the base end to the tip end is longer than that of the upper piece 73 in the seventh aspect.

[0102] According to this embodiment, the lower piece 74 can be easily bent, and the workability during assembly can be improved.

[0103] In the top plate 3 of the ninth aspect, in the eighth aspect, the lower piece 74 has an introduction piece 742 formed at its tip and inclined relative to the lower surface of the back layer 6 so as to extend downward as it moves away from the connection piece 75.

[0104] According to this embodiment, the outer peripheral ends of the front layer 5 and the back layer 6 can be easily fitted between the upper piece 73 and the lower piece 74, improving workability during assembly.

[0105] In the top plate 3 according to the tenth aspect, in the seventh aspect, the upper piece 73 has a portion whose protruding dimension from the base end to the tip is shorter along the direction from the first end X1 to the opposite second end X2 in the width direction perpendicular to the direction from the base end to the tip. The lower piece 74 has a portion whose protruding dimension is shorter along the direction from the second end X2 to the first end X1 in the width direction.

[0106] According to this embodiment, there are no restrictions on the vertical installation direction, so while maintaining ease of installation to the front layer 5 and back layer 6, there is no need to worry about the vertical orientation of the fixing member 7 during assembly, making it easy to assemble.

[0107] The cooking device 1 according to an eleventh aspect includes a device body 2 and a top plate 3 according to any one of the first to tenth aspects attached to the device body 2.

[0108] According to this embodiment, the cooking device 1 can be manufactured using a top plate 3 that fixes the surface layer 5 and the back layer 6 with appropriate fixing strength while not impairing assembly ease, thereby providing a cooking device 1 that is easy to assemble.
