JP-A-9-10053

  In a kitchen, particularly in a cooking space, cooking utensils such as a pan used for cooking on a stove (hereinafter simply referred to as a pan) may be placed. Since the pan is heated in the stove, it is very hot. For this reason, in the top plate using a metal plate instead of the synthetic resin as in Patent Document 1, thermal expansion occurs due to the heat of the placed pan bottom.

  According to the said structure, an adhesion layer and a heat sink are provided in the area | region corresponding to a cooking space among the top plates on the back surface of a surface material. Thereby, since the heat | fever of the pan bottom mounted on the surface material is thermally radiated by the heat sink, the thermal expansion of a surface material can be suppressed. Therefore, it is possible to prevent deformation due to bending due to thermal expansion and to favorably maintain the aesthetic appearance of the top board.

To do.

(System kitchen)
FIG. 1 is a diagram illustrating a system kitchen (hereinafter referred to as kitchen 100). As shown in FIG. 1, the kitchen 100 of the present embodiment is a so-called system kitchen including a plurality of storage cabinets (cabinets) under a single top plate 110 (work top). The top plate 110 is made of stainless steel and covers the entire upper surface of the kitchen 100. In addition, the top plate 110 is provided with a stove 112 attached in a built-in manner, a cooking space 114 which is a flat table surface and used mainly for cooking, and a sink 116.

  Under the top plate 110, the storage cabinet includes a stove cabinet 120 in which the main body of the stove 112 is installed, a base cabinet 130 corresponding to the cooking space 114, and a sink cabinet 140 in which the sink 116 is installed. Each storage box functions as a storage space, and an empty space in the storage box also contains wiring to the stove 112, a water supply / drain pipe to the sink 116 and the faucet, and the like.

(Cooking space)
FIG. 2 is a cross-sectional view of the cooking space 114 of FIG. As shown in FIG. 1, a cooking utensil such as a pan used for cooking in the stove 112 (hereinafter referred to as pan 102) is placed in the cooking space 114 between the sink 116 of the top plate 110 and the stove 112. Sometimes. As shown in FIG. 2, in this embodiment, the cooking space 114 is provided with a resin-based adhesive layer 152 and a metal heat dissipation plate 154 on the back surface of the top plate 110, which is a stainless steel surface material. . In the present embodiment, the adhesive layer 152 is exemplified by an acrylic resin system. The lower side of the heat sink 154 is supported by the stove cabinet 120, the base cabinet 130, and the sink cabinet 140 shown in FIG.

  According to the said structure, the heat sink 154 is arrange | positioned by the contact bonding layer 152 in the area | region corresponding to the cooking space 114 among the top plates 110 on the back surface. Thereby, since the heat of the surface material, ie, the bottom of the pan 102 placed on the top plate 110 of the cooking space 114, is radiated to the heat radiating plate 154, the thermal expansion of the surface material can be suppressed. Therefore, it is possible to prevent deformation due to bending due to thermal expansion, and favorably maintain the aesthetic appearance of the top plate 110.

  In addition, as a metal used for the heat sink 154, iron (zinc iron plate) can be illustrated, for example. Moreover, copper, aluminum, and duralumin can be illustrated as another metal. Since copper, aluminum, and duralumin have higher thermal conductivity than iron, it is possible to further improve heat dissipation. The general thermal conductivity of these metals is iron 84 W / mK, copper 403 W / mK, aluminum 236 W / mK, duralumin 130-190 W / mK. In this embodiment, the structure using the heat sink 154 of a zinc iron plate is illustrated.

  FIG. 3 is a diagram for explaining the thickness of the surface material, the acrylic resin-based adhesive layer 152 and the heat dissipation plate 154. FIG. 3A is a diagram illustrating the thickness of the surface material (top plate 110) and the adhesive layer 152 when the thickness of the heat dissipation plate 154 is 2.3 mm. FIG. 3B is a diagram for explaining the thickness of the surface material (top plate 110) and the adhesive layer 152 when the thickness of the heat radiating plate 154 is 3.2 mm.

  3 (a) and 3 (b), the heated pan 102 is placed in the cooking space 114, and after a predetermined time has passed, a thermal expansion test is performed in which the pan is removed 10 times. As a result of visual observation, The case where the surface material (top plate 110) is not deformed is indicated by ◯, and the case where the surface material (top plate 110) is deformed is indicated by x. As the surface material, stainless steel plates having a thickness of 0.65 mm, 0.8 mm, 1.0 mm, and 1.2 mm were used. The thickness of the adhesive layer 152 was 10 μm, 50 μm, 100 μm, 300 μm, and 600 μm.

  As shown in FIG. 3A, when the thickness of the heat sink 154 is 2.3 mm, the thickness of the surface material is 0.65 mm to 1.2 mm when the adhesive layer 152 is 50 μm to 100 μm. However, no deformation of the surface material occurred. Similarly, as shown in FIG. 3B, when the thickness of the heat sink 154 is 3.2 mm, the thickness of the surface layer is any of 0.65 mm to 1.2 mm when the adhesive layer 152 is 50 μm to 100 μm. Even in this case, the surface material was not deformed. From this, it can be understood that the thickness of the adhesive layer is preferably 50 μm to 100 μm.

  Next, as shown in FIG. 3B, when the thickness of the heat dissipation plate 154 is 3.2 mm, the thickness of the surface material is within the range of 1.0 mm to 1.2 mm, which is related to the thickness of the adhesive layer 152. Without deformation of the surface material. From this, it can be understood that when the thickness of the surface material is 1.0 to 1.2 mm, the thickness of the heat dissipation plate 154 may be 3.2 mm or more.

  Further, as shown in FIG. 3A, when the thickness of the heat sink is 2.3 mm, the surface material of any thickness is deformed when the thickness of the adhesive layer 152 is 10 μm. When the thickness of the surface material is 1.2 mm, the surface material is not deformed if the adhesive layer 152 is 50 μm or more. As shown in FIG. 3B, even when the thickness of the heat sink 154 is 3.2 mm, no deformation occurs when the thickness of the surface material is 1.2 mm and the thickness of the adhesive layer 152 is 50 μm or more. . From this, it can be understood that the deformation of the surface material can be prevented by setting the surface material to 1.2 mm or more and the adhesive layer 152 to 50 μm or more.

  FIG. 4 is a diagram showing the relationship between the thickness of the acrylic resin adhesive layer 152 and the tensile strength. The tensile strength test was performed in an 80 ° C. atmosphere. As shown in FIG. 4, in the test body having the adhesive layer 152 of 10 μm, the tensile strength is about 80 kPa, and the tensile strength increases as the thickness of the adhesive layer 152 increases. The tensile strength when the thickness of the adhesive layer 152 is 50 μm is about 160 kPa, and the tensile strength when the thickness of the adhesive layer 152 is 540 μm is about 300 kPa.

  Considering the data of FIG. 4 together with the data of FIGS. 3A and 3B, if the tensile strength of 160 kPa or more can be obtained by setting the thickness of the adhesive layer 152 to 50 μm or more, the surface material and the heat sink 154 It is considered that sufficient adhesive strength with the adhesive layer 152 can be secured. As a result, it is speculated that the heat from the pot 102 can be suitably radiated from the surface material to the heat radiating material, and deformation of the surface material can be prevented.

  5 and 6 are diagrams for explaining heat transfer in the cooking space 114. 5A illustrates the case where the thickness of the adhesive layer 152 is thin (100 μm), and FIG. 5B illustrates the case where the thickness of the adhesive layer 152 is thick (300 μm). 6A illustrates the case where the thickness of the surface material (top plate 110) is thick (1.2 mm), and FIG. 6B illustrates the case where the thickness of the surface material (top plate 110) is thin ( 0.8 mm).

  When the thickness of the adhesive layer 152 is thick as shown in FIG. 5B, the heat applied to the surface material (top plate 110) is confined to the adhesive layer 152 having a low thermal conductivity, and the heat to the heat sink 154 is increased. It is considered that the transmission efficiency is lowered. As a result, it is presumed that the heat radiation to the heat radiating plate 154 becomes insufficient and the surface material (top plate 110) is deformed so as to be swollen. On the other hand, as shown in FIG. 5A, when the thickness of the adhesive layer 152 is thin, heat applied to the surface material (top plate 110) passes through the adhesive layer 152 and is efficiently transmitted to the heat radiating plate 154. The Thereby, it is inferred that heat is sufficiently radiated from the surface material (top plate 110) to the heat radiating plate 154, and the surface material (top plate 110) is not deformed.

  As shown in FIG. 6A, when the surface material (top plate 110) is thick, heat is sufficiently diffused in the surface material (top plate 110). Thereby, it is considered that local heat retention of the surface material (top plate 110) is suppressed, and deformation of the surface material (top plate 110) is prevented. On the other hand, when the thickness of the surface material (top plate 110) is thin as shown in FIG. 6B, heat cannot be sufficiently diffused in the surface material (top plate 110). For this reason, it is considered that heat stays locally and the surface material (top plate 110) is deformed so as to be swollen.

  Referring to the results of FIG. 6, it can be considered that the heat sink 154 and the adhesive layer 142 are unnecessary if the top plate 110 is thickened. However, stainless steel plates are difficult to process such as bending and drawing, and the processing difficulty increases dramatically with increasing thickness. Therefore, it is preferable that the stainless steel plate of the surface material is thin and the heat radiating plate 154 is disposed by the adhesive layer 142.

  FIG. 7 is a diagram comparing the thermal conductivity and thermal softening temperature of the adhesive. In the said embodiment, it demonstrated using the acrylic resin-type adhesive agent as an adhesive layer. However, the present invention is not limited to this, and adhesives of other materials may be used.

  As described above, the phenomenon that the surface of the top plate 110 is swollen is considered to be caused by the linear expansion of the stainless steel surface material due to heating and the decrease in cohesive force due to the temperature increase of the adhesive. Accordingly, the performance parameters required for the adhesive layer 152 include the thermal softening temperature and the thermal conductivity, as well as the thickness that affects the heat transfer to the back side. In other words, if the heat softening temperature and the thermal conductivity are approximately the same, the thickness can be approximately the same.

  Accordingly, referring to FIG. 7, the acrylic resin adhesive and the epoxy resin, urethane resin, and silicon resin adhesive have the same thermal softening temperature and thermal conductivity. Therefore, it can be seen that the effects of the present invention can be obtained with the same thickness as the acrylic resin-based resin layer even when an adhesive made of these materials is used.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.

  The present invention can be used for a stainless steel top plate and a kitchen counter or system kitchen provided with such a top plate.
