Description

[Technical Field]

[0001] The present invention relates to a silicone mat for preventing movement of a cooking appliance, a silicone mat set, and a method for preventing movement of a cooking appliance. [Background technology]

[0002] Conventionally, cooking appliances (e.g., microwave ovens, toasters, etc.) have used stoppers on the bottom legs of the appliance to prevent it from moving. Alternatively, a microwave stopper with an L-shaped base and adhesive mats on the bottom and back (side) sides is attached to both sides of the appliance, and the adhesive surfaces of the two adhesive mats secure the appliance to prevent movement and vibration (Patent Document 1). A product equivalent to Patent Document 1 is sold by the same applicant, Pro Seven (Non-Patent Document 1). Microwave stoppers are available in two-piece and four-piece types, and are used depending on the seismic load. These types show examples of securing a microwave oven using L-shaped polycarbonate and adhesive pads (adhesive gel).

[0003] Another example of a movement-suppressing member is an anti-slip member for furniture legs, although the object is not cooking equipment (Patent Document 2). This is an anti-slip member placed at the bottom end of a furniture leg, and is provided with a continuous wall portion that abuts against the furniture leg on part of a plate-shaped base material, and anti-slip portions attached to the top and bottom surfaces of the base material. The anti-slip portions are formed by attaching a plate-shaped material made by compressing and molding fiber or a rubber material to the base material. [Prior art documents] [Patent documents]

[0005] [Non-Patent Document 1] https: / / ite.rakuten.co.jp / kashitani / pro7p12n3402w-f / (Pro7 Earthquake-Resistant Kitchen Microwave Stopper Mat for Earthquakes of Intensity 7) Summary of the Invention [Problem to be solved by the invention]

[0006] In the above Patent Document 1 and Non-Patent Document 1, in order to suppress or prevent movement, some processing of the non-fixed body and the ground surface is required, the installation work is complicated and troublesome, and the non-fixed body and the ground surface are presumed to be "bonded" or "fixed" to each other. Once "bonded" or "fixed", there are problems in that removal is not easy and cleaning is inconvenient.

[0007] The above-mentioned Patent Document 1 states that the adhesive pad is made of "urethane elastomer," and Non-Patent Document 1 describes the earthquake-resistant mat on its website as having an "adaptable temperature range of 20°C to 75°C." Although it is described as being for microwave ovens, it is believed that it is not suitable for microwaves because the surface temperature of the microwave can exceed 100°C when using the heater (oven or grill function) or steam.

[0008] In the above Patent Document 2, the wall portion of the anti-slip member is formed continuously, and since there are many different cooking appliances with different leg shapes and sizes, one type of anti-slip member cannot be used to accommodate many different types of cooking appliances.

[0009] The purpose of this invention is to solve the above-mentioned conventional problems by providing a silicone mat for cooking appliances that exerts a strong movement-inhibiting effect simply by placing it under the legs of the object, and that is also easy to remove and reinstall, and a silicone mat set for the mat. [Means for solving the problem]

The two opposing sides of the cooking appliance have no edges that protrude upward, and when viewed from above, a flat structure is arranged over the entire upper surface excluding the edges, and the two silicone mats are arranged so that the two legs arranged at one diagonal corner of the four legs at the bottom of the cooking appliance have edges that protrude upward on the two opposing sides in the first direction, and the two silicone mats are arranged so that the two legs arranged at the other diagonal corner of the four legs at the bottom of the cooking appliance have edges that protrude upward on the two opposing sides in the second direction (corresponding to claim 5). [Effects of the Invention]

[0016] According to the present invention, it is possible to realize a silicone mat and a silicone mat set for cooking appliances that can exert a strong movement-inhibiting effect simply by placing it under the legs of the object, and that can also be easily removed and reinstalled.

[0018] The silicone mat for preventing movement of cooking appliances and the silicone mat set according to the present invention are described in detail below with reference to the accompanying drawings. The following embodiments include not only the essential features of the present invention but also features that can be selectively adopted and features that can be combined as appropriate.

[0019] <Embodiment> The silicone mat for preventing movement of cooking appliances according to an embodiment of the present invention is a silicone mat for preventing movement of cooking appliances that is placed at the bottom ends of the legs of the cooking appliance, and has a hardness of 50 to 70, and the top and / or back surface of a flat structure made using a mold polished with a ceramic grindstone of grit size #1000, and is rectangular in shape.

[0020] <Configuration> As shown in Figures 1 and 2, the silicone mat 1 for cooking appliances according to this embodiment has a two-edge structure with edges 2 and 3 on opposing surfaces. The cross section II of Figure 1(a) has a flat structure in the area between edges 2 and 3, as shown in Figure 1(b). The flat structure surface area is rectangular. This is because if edges 2 and 3 were continuous, the installation patterns for the legs of cooking appliances with a wide variety of shapes would be limited. If the object attempts to move beyond the movement-restraining effect of the top surface of the flat structure surface area, edges 2 and 3 provide an additional movement-restraining effect. Here, since the target cooking appliance is a heating cooking appliance, a material with the unique movement-restraining effect (resistance to slippage) and heat resistance that silicone provides is desirable, and therefore silicone was used.

[0021] Since most cooking appliances have four legs arranged symmetrically, a regular square is desirable for the silicone mat 1. However, this regular square also includes shapes that are nearly regular squares. By installing a silicone mat 1 with a two-edge structure on the bottom end of each of the four legs of the cooking appliance (forming a silicone mat set) and devising a silicone mat installation pattern, it is possible to achieve a double movement prevention effect in addition to the silicone's movement prevention effect. Even if a cooking appliance placed on a kitchen table, etc., is accidentally pushed to the edge of the silicone mat due to prolonged shaking from an earthquake, a double movement prevention effect can be achieved in any direction by installing four mats with a two-edge structure alternately at 90 degrees.

[0022] The silicone mat's two-edge structure allows it to accommodate a wide variety of leg shapes for cooking appliances. The reason for the two-edge structure is that cooking appliances, such as microwave ovens, have a variety of leg shapes, from simple four-legged ones to complex strip-like ones, and if all four sides were surrounded by edges, some leg shapes would not be able to be installed.

[0023] The silicone mat shown in Figure 2 was manufactured using a mold described below. In the example shown in Figure 2, silicone mat 1 is a regular square with a side length of 100 mm, edges 2 and 3 having widths of 7 mm, the flat structure surface area constituting the non-slip portion having a length of 86 mm, edges 2 and 3 having heights of 6 mm, and the convex portions of edges 2 and 3 having heights of 3 mm. These values ​​were determined as a result of tests in which the mat was installed on the lower legs of a wide variety of cooking appliances, as shown in the installation patterns shown in Figures 10 to 14 below. The width of the edges on the two opposing sides of the silicone mat is applicable as long as it is 0.5 to 10% or less of the length of one side. However, it goes without saying that the values ​​are not limited to these values, and may be changed as appropriate depending on various design changes.

[0024] Figures 3(a) and (b) show examples of silicone mats installed on the bottom legs of a cooking appliance. Figure 3(a) shows an example in which silicone mats 1a, 1b, 1c, and 1d are placed on a kitchen table or the like, and bottom legs 5a, 5b, 5c, and 5d of a microwave oven 4, which is a cooking appliance, are installed. Figure 3(b) shows a view from the bottom, with the installation surface of Figure 3(a) turned upside down. Silicon mat 1b is rotated 90 degrees relative to silicone mat 1a. Silicon mat 1d is also rotated 90 degrees relative to silicone mat 1c. The reversed arrangement pattern is also possible.

[0025] Figures 4(a) and (b) show examples of basic installation patterns for silicone mats. This installation pattern uses a set of four silicone mats, staggered at 90 degrees, to provide a two-edge structure that prevents movement. Even if the cooking appliance shakes due to vibrations such as an earthquake, or if force is applied to the appliance's legs 5a, 5b, 5c, and 5d, the anti-slip effect can be maintained.

[0026] Figure 5 explains the manufacturing process for a single-cavity silicone mat mold 6 (male mold) and mold 7 (female mold). The basic shape of the mold is created using NC machining or other methods. Then, a mirror finish is applied as a finishing process. First, the surface is polished with coarse grinding stones 8 and 9. Then, it is polished with low-grit sandpaper 10, followed by gradually finer sandpaper 11 and 12. Finally, the surface is polished with a 1000-grit ceramic grinding stone to obtain a smooth (mirror) surface. Figure 6 shows the mirror-finishing process performed by a worker. As shown in Figure 6, the surface of mold 7 (female mold) is polished with a 1000-grit ceramic grinding stone 13. Similarly, although not shown, the surface of mold 6 (male mold) is polished with a 1000-grit ceramic grinding stone 13.

[0027] Examples of the nine-cavity main mold 15 (female mold) and main mold 16 (male mold) manufactured in this way are shown in Figures 7(a) and (b). Figure 9 shows the main mold 15 (female mold) with a smooth mirror finish. Figure 8 shows the main mold 16 (male mold) with a smooth mirror finish.

[0028] Using the mold thus produced, silicone mats with hardness ranging from 50 to 70 were produced and subjected to a movement suppression vibration test as shown in Figure 15. The results of this movement suppression vibration test (performance evaluation experiment) are shown in Figures 16 and 17.

[0029] Figure 16 shows an example in which a microwave oven was used as the target cooking appliance. In Figure 16, the microwave oven, manufacturer: Company B, model number: B001, dimensions: 500 x 450 x 388 mm, weight: 18 kg, vibration time: 20 seconds, was set, and the distance traveled by the left and right legs was measured. The experimental environment was as shown in Figures 15(a) and 15(b), where the microwave oven (or toaster) was placed on a vibration table fixed to a vibration device (not shown). The vibrations of the vibration device (not shown) were transmitted to the vibration table, and the distance traveled by the right and left legs of the microwave oven (or toaster) was measured. For comparison, no mat and a non-slip sofa mat were used. The silicone mats used in this Example 1 had a hardness of 50, those in this Example 2 had a hardness of 60, those in this Example 3 had a hardness of 70, and those in this Example 4 had a hardness of 50 and a mirror finish. As is clear from Figure 16, the 50 hardness of Examples 1 and 4 provided the best movement suppression effect.

[0030] Figure 17 shows an example using a toaster as the target cooking appliance. In Figure 17, the toaster, manufacturer: Company A, model number: A001, dimensions: 377 x 271 x 225 mm, weight: 2.8 kg, vibration time: 30 seconds, and the movement distance of the left and right legs was measured. The experimental environment was the same as that shown in Figures 15(a) and 15(b) above. For comparison, no mat and a sofa's anti-slip material were used. The silicone mats used in this Example 1 had a hardness of 50, in this Example 2 a hardness of 60, in this Example 3 a hardness of 70, and in this Example 4 a hardness of 50 with a mirror finish. As is clear from Figure 17, the 50 hardness of Examples 1 and 4 provided the greatest movement suppression effect. In addition, since this example is scheduled to be released in the future, the product name is listed.

[0031] The silicone mat of this embodiment can be installed on cooking appliances with leg heights of 3 mm or more and widths (short sides) of 85 mm or less. Since the shape of the legs varies depending on the model of cooking appliance, examples of installation patterns are shown in Figures 10(a), (b), (c), 11(a), (b), (c), 12(a), (b), (c), 13(a), (b), (c), and 14(a) and (b). Fig. 10(a) is an example of a cooking appliance with only round legs, Fig. 10(b) is an example of a cooking appliance with round and square legs (horizontal), Fig. 10(c) is an example of a cooking appliance with round and square legs (vertical), Fig. 11(a) is an example of a cooking appliance with some legs attached to the protruding part of the body (usable if the leg height is 3mm or more), Fig. 11(b) is an example of a cooking appliance with all legs attached to the protruding part of the body (usable if the leg height is 3mm or more), Fig. 11(c) is an example of a cooking appliance with some legs attached to the protruding part of the body (usable if the leg height is 3mm or more), Fig. 12(a) shows an example of a cooking appliance with only rounded, angular legs, Fig. 12(b) shows an example of only oval legs, Fig. 12(c) shows an example of round and small rectangular legs, Fig. 13(a) shows an example of round and oval legs, Fig. 13(b) shows an example of some legs protruding significantly from the cooking appliance body, Fig. 13(c) shows an example of deformed legs, Fig. 14(a) shows an example of legs whose long side (vertical) exceeds 85 mm, and Fig. 14(b) shows an example of legs whose long side (horizontal) exceeds 85 mm. As such, this embodiment can be installed on the lower ends of the legs of a wide variety of cooking appliances.

[0032] Thus, according to this embodiment, a movement-inhibiting silicone mat for cooking appliances and a movement-inhibiting silicone mat set are provided that can be placed under the legs of an object to exert a strong movement-inhibiting effect and are easy to remove and reinstall.
