Description

[Technical Field]

[0001] To provide moisture-proof furniture that can maintain the cleanliness of an open storage space for storing electrical appliances for kitchens such as an electric rice cooker and an oven range, can sufficiently maintain the inside and back surfaces, is resistant to moisture, and is easily adapted to stains. [Background technology]

[0002] A proposed furniture front panel has high strength and durability, in which the backside of a surface panel covered with melamine board, which has excellent impact resistance, heat resistance, and abrasion resistance, is decorated. The front panel is a panel board used for melamine-covered furniture front panels, and uses a core material of the panel board and MDF 18 to 25 mm thick and 250 to 800 mm wide. The melamine board is covered on the surface, and a 0.1 to 0.2 mm thick vinyl chloride wrapping sheet is attached to the entire surface of the sides and backside of the MDF core material, with high adhesive strength and in a uniform and smooth manner, resulting in decoratively uniform corners on the sides and backside (see Patent Document 1).

[0003] Most cupboards, which are primarily used to store tableware, use printed decorative panels, medium-density compressed plywood (MDF), particle board, and other structural materials. Furthermore, many cupboards have open storage spaces for storing electrical kitchen appliances such as electric rice cookers, microwave ovens, and electric kettles. However, when steam-generating appliances such as electric rice cookers and electric kettles are used in the open storage spaces, the steam comes into contact with the cupboard's structural materials, such as medium-density compressed plywood (MDF) or particle board, and these materials absorb moisture, causing them to expand and significantly shortening the cupboard's lifespan.

[0004] Therefore, when using electrical appliances that emit steam, it is necessary to place the appliances on a sliding counter separately attached to the floor of the open storage space of the cupboard, pull the counter out, and use them in a position where the steam does not directly hit the cabinet.

[0005] In furniture, electrical appliances that emit steam have traditionally had to be pulled out of the opening storage space 1 because they are vulnerable to steam and can cause damage. However, by taking measures to prevent damage to the furniture, it is now possible to use the appliances stored inside the opening storage space without having to pull them out, thereby ensuring a larger work space and improving safety when working in the kitchen.In order to ensure a larger work space and improve safety when working in the kitchen, it has been reported that furniture with an opening storage space 1 has been waterproofed and airtightly treated using water-resistant materials for the joints of the main body that make up the opening, in order to prevent damage to the wooden parts due to the penetration of steam emitted from the electrical appliances (see Patent Document 2).

[0006] In this case, every time an electrical appliance that emits steam is used, the sliding counter must be pulled out, meaning that the appliance will be protruding from the cupboard, which not only obstructs the flow of movement in the kitchen, but also means that the appliance, which can become very hot, will be used in an unstable and dangerous position protruding into the space.Furthermore, as the appliance is used frequently and gets dirty frequently, it is expected that the surface will be easy to clean.

[0007] This prevents moisture from building up on clothing and other items inside furniture. To prevent mold from growing on the wall behind the furniture, a blower unit with a fan is attached to a part of the wardrobe, and the air generated by this blower unit is circulated through vents formed inside the wardrobe. This blower unit is driven by a control circuit according to the humidity inside the wardrobe, maintaining an ideal dry state at all times. It has also been proposed to prevent mold from growing on the wall by blowing air from the blower unit into the gap between the wardrobe and the wall behind it (see Patent Document 3).

[0008] Humidity-regulating materials such as calcium silicate boards are often used to absorb moisture in furniture, but in places where they are used frequently, stains can form and can be difficult to wipe off, resulting in an unsightly appearance. Materials that can absorb moisture and can be wiped clean are desired. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Utility Model Registration No. 3216646 [Patent Document 2] Utility Model Registration No. 3122453 [Patent Document 3] Japanese Patent Application Laid-Open No. 2003-9959 Summary of the Invention [Problem to be solved by the invention]

[0010] The present invention aims to provide furniture, particularly cupboards, with open storage spaces for storing electric kitchen appliances such as electric rice cookers and microwave ovens. Conventionally, the open storage spaces of cupboards have been vulnerable to steam, causing damage to the appliances, and so the appliances had to be pulled out of the open storage spaces. However, by increasing the steam resistance of the cupboard, the appliances can be safely stored inside the open storage spaces without being pulled out of the open storage spaces, preventing damage caused by expansion and contraction due to moisture and heat from steam. Furthermore, the use of electric kitchen appliances such as electric rice cookers and microwave ovens can often result in food splashing and stains on the walls, which can make cleaning difficult from the standpoint of cleanliness and hygiene. The particular objective is to make the open storage spaces of furniture clean and safe. [Means for solving the problem]

[0011] The present invention is a means of solving the problem of furniture with an opening storage space for storing electrical kitchen appliances such as electric rice cookers and microwave ovens, by using water-resistant materials to provide airtight waterproofing for the joints of the body opening, where the wood may be damaged by the penetration of water vapor.

[0012] This furniture has an open storage space for storing electric kitchen appliances such as electric rice cookers and microwave ovens. To prevent damage caused by expansion and contraction of the wooden parts due to moisture absorption caused by the water vapor and moisture permeating from the appliances, the walls of the appliance storage area are made of a sandwich-type moisture-proof sheet with polyethylene resin between them, or a moisture-proof material made by pasting the back of reinforced paper coated with a silicone film to a flat MDF plate, making it moisture-resistant furniture.

[0013] The moisture-proof material is a thin moisture-proof MDF material in which a moisture-proof sheet made of 0.02 to 0.03 mm reinforced paper sandwiched between 0.03 to 0.07 mm thick polyethylene resin, or reinforced paper coated with a 0.02 to 0.05 mm thick silicone film is attached to both sides or one side of a flat MDF plate having a thickness of 2 to 5 mm.

[0014] The moisture-proof sheet has a high surface tension of water droplets on its surface, which is the wettability index of the material surface when it is moist, and also maintains the property of easily absorbing and retaining moisture. The surface also easily absorbs and releases moisture, making it easy to remove contaminated areas by wiping. It has a moisture absorption rate of 2 to 10%, but maintains the property of not allowing moisture to penetrate to the back side, and the surface also easily absorbs and releases moisture, making it easy to remove dirt by wiping.

[0015] Moisture-proof materials are used on 2 to 5 sides of the interior of the appliance storage area in furniture where moisture is likely to build up, or on the back area where moisture ventilation is poor, covering an area of ​​0.2 to 0.8 m2 within a volume of 200 to 1000 L of the appliance storage area, and on 50 to 100% of the back area. [Effects of the Invention]

[0016] By ensuring steam resistance inside the open storage space of furniture with this invention, it has become possible to safely use electrical appliances that emit steam while they are stored in the open storage space, ensuring a large work space for safe kitchen work and improving safety. Furthermore, cleaning the inside of the open storage space is easy, as dirt does not stick to the wall but floats to the surface, making it easy to remove, and the interior can be kept sufficiently clean. [Brief explanation of the drawings]

[0017] [Figure 1] 1A and 1B are front and rear views of an embodiment of furniture with an open storage space for storing kitchen electrical appliances. [Figure 2] FIG. 10 is a diagram showing the location where moisture-proof material is attached inside the open storage space of furniture in an embodiment. [Figure 3] FIG. 4 is an enlarged view of the open storage space of the embodiment.

[0018] It is advisable to use silicone bond to waterproof and airtighten the joints of openings where steam penetration could damage the wood, and also to use melamine or aluminum boards, which have excellent steam resistance, for the surface materials of the open areas, i.e. the top, left and right side panels, and back panel. Also, regarding airtightness, there is a method of directly sealing the joints of the components with silicone bond alone, but considering the deterioration of the silicone over long-term use and the design, it is thought that the best method is to use silicone bond and then cover the joints with plastic or aluminum. [Example]

[0019] As shown in Figure 1, in a wooden cupboard with an opening storage space for storing electrical kitchen appliances such as an electric rice cooker and a microwave oven, moisture-proof materials were used in the cupboard at locations shown in Figures 1 and 2 to provide waterproof and airtight processing for the joints of the components at the opening of the main body, where there is a risk of damage to the wood due to the penetration of water vapor, to ensure airtightness against steam.

[0020] In wooden cupboards with open storage spaces intended for storing electric kitchen appliances such as electric rice cookers and microwave ovens, in order to prevent damage caused by expansion and contraction of the wooden parts due to moisture absorption caused by the steam and humidity generated by the appliances, the walls of the open storage area are lined with a moisture-proof sandwich sheet (A in Figure 4) made of waterproof polyethylene resin sandwiched between reinforced paper and pasted onto a flat MDF board, creating a moisture-proof piece of furniture that is resistant to moisture and is used in the appliance storage area.

[0021] The moisture-proof material was a thin sheet of moisture-proof MDF, made by pasting a moisture-proof sheet made of 0.05mm thick polyethylene resin sandwiched between 0.025mm thick reinforced paper on one or both sides of a 3mm thick flat MDF plate.

[0022] The moisture-proof sheet has a high surface tension of water droplets on the surface, which is the wettability index of the material surface when it is moist, and also has a moisture absorption rate of 5%, but it maintains the property of being impermeable to the back side, and moisture absorption and dissipation are easy on the surface, making it easy to remove dirt by wiping off dirty areas.

[0023] The area of ​​the four sides of the appliance storage area (Fig. 3), which is prone to moisture buildup, is 0.4 m 2 Alternatively, moisture-proofing material was applied to the top 50% of the back surface, where there is little ventilation. After repeatedly filling the furniture with water vapor and then drying it out over a long period of time, there was no deformation or warping of the furniture, and no peeling of the surface coating sheet was observed. [Example]

[0024] In furniture with an open storage space intended for storing electric kitchen appliances such as electric rice cookers and microwave ovens, in order to prevent damage caused by expansion and contraction due to moisture absorption by the wooden parts caused by steam generated by the appliances and penetration of moisture, the walls of the open storage area and the backside of the plywood attached to the cupboards are lined with a sandwich-type moisture-proof sheet (0.1 mm) made of polyethylene resin sandwiched between reinforced paper, and a moisture-proof material made of reinforced paper coated with a silicone film (0.025 mm) glued to a flat MDF plate, making the furniture moisture-resistant.

[0025] The moisture-proof material was a thin sheet of MDF board, made by pasting a moisture-proof sheet made of 0.05mm thick polyethylene resin sandwiched between 0.025mm thick reinforced paper on one or both sides of a 3mm thick MDF board. The moisture-proof sheet had a high surface tension for water droplets on its surface, which is the wettability index of the material surface when exposed to moisture, and had a moisture absorption rate of 5%, but maintained the property of not being able to penetrate the 3mm plywood on the backside. Moisture absorption and dissipation were also easy on the surface, making it easy to wipe away dirt in dirty areas.

[0026] In furniture, moisture-proofing material should be applied to 2 to 5 sides of the interior of the appliance storage area where moisture is likely to occur, or to the back area where moisture is scarce and ventilation is poor, within 0.5 m of the interior of an 800 L open area. 2 The furniture was filled with steam and then dried repeatedly over a long period of time, but there was no deformation or warping of the furniture, and no peeling of the surface covering sheet was observed. [Example]

[0027] In a wooden cupboard with an open storage space intended for storing electric kitchen appliances such as electric rice cookers and microwave ovens, in order to prevent damage caused by expansion and contraction due to moisture absorption by the wooden parts caused by steam generated by the appliances and penetration of moisture, a moisture-proof material was used on the walls of the open storage area, with the back of reinforced paper coated with a silicone film attached to a flat MDF plate, and on the back, a sandwich-shaped moisture-proof sheet of approximately 0.1 mm thickness made of reinforced paper sandwiched between polyethylene resin and attached to a 3 mm MDF plate.

[0028] The structures are shown under a magnified microscope in Figures 4A and 4B. The moisture-proof material was a laminated moisture-proof sheet (Figure 4A) of 3mm-thick MDF, consisting of approximately 0.03mm reinforced paper laminated to both sides of a 0.04mm-thick polyethylene resin sheet, or a thin sheet of moisture-proof MDF, consisting of reinforced paper coated with a 0.025mm silicone membrane. The moisture-proof sheet (Figure 4A) and the silicone-coated reinforced paper (Figure 4B) were structured as shown in Figure 5, consisting of a cellulose layer, a polyethylene layer, and a cellulose layer, with the polyethylene layer blocking moisture. The silicone-coated reinforced paper (Figure 4B) also had a silicone layer and a cellulose layer, with a 0.025mm silicone membrane on the surface, confirming the paper component as the base.

[0029] The moisture-proof sheet has a high surface tension of water droplets on its surface, which is the wettability index of the material surface when it is moist, and also maintains the property of absorbing and retaining moisture easily. The surface also easily absorbs and releases moisture, making it easy to remove contaminated areas by wiping. It maintains a moisture absorption rate of 5 to 10%, but maintains the property of being impermeable to the backside, and the surface also easily absorbs and releases moisture, making it easy to remove dirt by wiping on contaminated areas. Moisture-proof material was applied to 0.7m3 of the interior of a 500L storage area for appliances in furniture prone to moisture. 2 It was used on the area of ​​80% of the back where there is less ventilation and humidity.
