JP4501837B2 - Home appliances and air conditioners using recycled resin - Google Patents

Description

  The present invention relates to a technique for effectively using a collected plastic material or the like again in a product among materials collected by disassembling and separating waste and increasing the utilization rate of a resin to be recycled.

  Due to the enforcement of the Home Appliance Recycling Law in April 2001, wastes such as air conditioners (air conditioners), refrigerators, and televisions are collected in large quantities at the recycling center. Separation work, crushing of products by crushing machine, and sorting of materials such as iron, copper, aluminum and plastics by sorting machine. When iron, copper, and aluminum are reused, they are dissolved by high heat treatment. Therefore, they are easily reused with little influence of foreign matters, impurities, dirt, etc. attached to waste, and are reused as valuable resources. However, plastics have various plastic materials and colors, and only a part of them that can be easily recycled can be reused as raw materials, and the rest can be buried with dust or used as a fuel only once.

In order to make recycling easy for such plastics, there is a proposal in Patent Document 1 for forming the surface of a plastic part to indicate the constituent material and grade of the part, and the color tone and reproduction of the plastic molded product. A proposal for displaying the number of times of use, a time limit, and the like is disclosed in Patent Document 2, and an indication of how much virgin resin material is added to the recycled resin material in recycling is disclosed in Patent Document 3. Yes. In addition, a synthetic resin assembly made of the same material is stored with indications indicating that this assembly should not be disassembled, proposals expressed by symbols or specific characters, or disassembly types and disassembly procedures such as valuable products and crushing defective products Such proposals are disclosed in Patent Documents 4 and 5 and the like. Further, Patent Document 6 discloses a technology that enables recycling of a coated molded product to which a coating film is attached.

  The application of the Home Appliance Recycling Law initially targeted large home appliances such as air conditioners (air conditioners), refrigerators, and televisions, but is now spreading to small home appliances, office automation equipment such as personal computers, and automobiles. In this way, as the recycling goes on track, of the waste that is discharged in large quantities, the recovery rate of collecting and reusing plastic instead of just landfilling or using it for fuel has become a problem. ing. However, various plastic materials are used for plastics in response to the increase in product types, and various colors are also used, so that dust treatment and energy problems can be solved so that products made from these materials can be used. Establishing environmental protection technology measures has become an urgent task.

  However, the range of physical properties of plastics collected from waste, for example, classified according to the material labeling of used home appliances, is very wide. With this classification, there are many types of plastic parts that can be separated and collected for use. There is a problem of becoming too much. Further, when the molded product is returned to a plastic material (hereinafter referred to as “recycled plastic”) for reuse, the physical property value varies between the collection and recycling units (hereinafter referred to as “lot”). Further, if it is attempted to adjust the physical property values in order to correct the variation, inspection costs and adjustment costs are required. Parts collected from various used home appliances vary depending on the attached foreign matter, impurities, dirt, etc., and it is necessary to select whether it can be reused, and also to perform sufficient cleaning processing etc. Therefore, there is a problem that the price of recycled plastic becomes higher than that of new plastic (hereinafter referred to as “virgin plastic”).

In the case of plastics, many types have been developed for various purposes, and the characteristics differ depending on the purpose, such as insulation performance, mechanical strength performance, and color tone. Moreover, due to intensifying development competition, products with superior characteristics are being manufactured more cheaply. For this reason, even if it tries to reuse the raw material reproduced | regenerated from the waste product, the exact same material is not necessarily obtained. Therefore, even if it is effective to display what kind of material is used in manufacturing, even if it is displayed that the original material characteristics can be maintained by mixing what and how much into the recovered material, recycling after 10 years, for example Sometimes the problem remains that it is necessary to verify whether the display is valid. In addition, since plastics of various colors are mixed in the collected plastics, plastic parts having free colors cannot be obtained even if they are recycled, so that the places where the recycled plastics are used are limited. For these reasons, there is a problem that only a small part that can be easily recycled is reused, and the application range of recycled plastic does not widen. In addition to the recycling of plastics, the reuse of metal parts and the like is effective. However, since there is no reuse system, there is a problem that recycling energy is required due to the idea of returning to materials.

    An object of the present invention is to obtain a product and a manufacturing method that recycles a plastic material recovered from waste and effectively uses the plastic material. Furthermore, the present invention increases the rate of reuse of parts such as plastic collected from waste, and makes it possible for anyone to grasp the weight of recycled plastic molded products used in products at any time, thereby protecting the global environment. The objective is to obtain the technology to promote.

The ratio of the total weight of the plastic to the total weight of the plastic parts of the main body, or the ratio of the total weight of the recycled material to the total weight of the main body is disclosed to the main body, enabling verification evaluation of the recycled plastic utilization rate. It is what.

  The air-conditioning apparatus of the present invention is a plurality of plastic moldings that are molded using recycled materials that melt and recycle plastic parts that have been separated and collected after manually disassembling heat exchangers composed of copper and aluminum from used products. The weight of the plastic molded product manufactured from the recycled material or the recycled material is used for the plastic molded product of all or main parts, and the body in the body using the plastic molded product The total weight of the recycled material, or the ratio of the total weight of the recycled material to the total weight of the plastic parts of the main body, or the ratio of the total weight of the recycled material to the total weight of the main body is displayed on the main body, or A catalog, a printed matter such as an instruction manual attached to the main body, or a tag attached to the main body, Readably stored in an electronic recording medium such as a C card, or is obtained by an information disclosure means is registered readably database discloses the material re-use state of the body via the Internet.

It can be increased. In addition, the present invention makes it possible for anyone to grasp the weight of recycled or reused products at any time, thereby accelerating the technological development competition for recycled plastics and the improvement competition for the utilization rate as a whole, and effective global environmental measures. To do.

Embodiment 1 FIG.
Hereinafter, the structure and recycling process of an air conditioner will be described in detail with reference to FIGS. 1 to 8 as an embodiment of the present invention. First, the configuration of the room air conditioner outdoor unit and the recycling process will be described as an example. FIG. 1 is a diagram showing an outline of the configuration of an outdoor unit. 2 and 6 show an exploded structure of the outdoor unit and names of parts. As shown in FIG. 1 and FIG. 2, reference numeral 105 denotes a compressor, and there is an outdoor electrical box that houses an outdoor control board 126, a reactor 118, capacitors 119, 120, and the like that are installed above the microcomputer. A blower 116 that is rotationally driven by a motor 117 is disposed inside the outdoor unit. In addition, the outdoor unit is formed of an iron front cover 102, a base 103, a back panel 109, and a top panel 114, and each panel is assembled with screws, fastening tools, elastic fixing tools, etc. Can be disassembled by hand. In addition, the fan cover 101 that protects the rotation of the fan, which is made of plastic, for example, polypropylene, is used for each panel. A service panel that can be easily shifted and removed during installation or service to check the inside of the outdoor unit or repair the refrigerant circuit. 108, a condenser net 112 is attached to hold and protect the outdoor heat exchanger 115.

FIG. 6 shows specific part names and main constituent materials. Inside the outdoor unit is a compressor 105 mainly composed of iron and copper, a pipe assembly 110 composed mainly of copper, a copper alloy mainly composed of stop valves 106 and 107, a four-way valve 111, and a motor support that supports an iron motor blower. 113, a separator 104 that partitions between the machine room and the ventilation chamber, and a metal that is a valuable material such as a heat exchanger 115 made of copper and aluminum is configured as the main body weight of the product. On the other hand, fan covers 101, service panels 108, and capacitor nets 112 are molded products mainly made of polypropylene PP, as large items using plastic materials as constituent materials. The outdoor fan 116 is molded by mixing glass, which is a styrene / acrylonitrile AS bi-fiber material, which can be increased in strength to rotate. The purchased control board 126 is mainly made of paper phenol, the terminal block 125 is flame retardant ABS, and a measuring element or an electrical product purchased and used as a component such as the lead wire 122 and the thermistor 123 shown in FIG. , 127 etc. use polyolefin resin as an insulator. Electrical components such as capacitors 119 and 120, fuses 124, diode elements 128 and the like, which are often partially decomposed and processed separately as valuables at the time of recycling, are also included.

  The above-described constituent materials are examples, and are changed to materials that are inexpensive and easy to handle, or changed to materials that have evolved according to purposes such as strength and flame retardancy. For example, many types of fibrous materials, such as glass fibers and carbon fibers, have been adopted depending on the purpose. Further, insulation of lead wires, which conventionally used vinyl chloride, has been replaced by a material that does not contain chlorine, such as polyolefin, that is, polypropylene, polyethylene, etc., as an environmental protection measure. A heat exchanger having a new structure is used, and a compressor or the like is mixed separately depending on the structure or the type of internal motor, and is often disassembled separately. Or the new structure etc. according to the objective may be adopted, and the internal structure of an outdoor unit is changed every year.

Next, FIGS. 3 and 4 are diagrams showing the configuration of the indoor unit, and FIG. 5 shows more detailed names of components and constituent materials. The enclosure of the indoor unit is formed of plastic such as the box 1, the front panel 2, the screw cap 3 that covers the screws, the suction grill 4, the corner box 6 that covers the corners, the air filter 7, and the vanes 12 and 13. The installation plate 5 is made of iron. Further, inside the outer enclosure portion, as shown in FIG. 4, a nozzle 11 which is mainly made of a plastic material and blows air from the indoor unit, a motor band 17 for fixing the motor, a motor cover 16, and a substrate Cover 23, terminal block holder 22, vane motor 26, fan motor 15, power cord 18, indoor control board 21, and heat exchanger 8 made of copper and aluminum, mainly made of iron. The electric component box 24 and the electric component cover 20 are configured. As the plastic material, many materials different from the outdoor unit shown in FIG. 6 are also used. In the indoor unit, because the design surface is important when placed indoors, heat resistance, etc., polystyrene is often used for the box 1, front panel 2, left and right vanes 14, etc., and acrylonitrile, butadiene, styrene ABS is used for the nozzle 11, Used for motor cover 16 and the like. Moreover, the structure and material which abbreviate | omitted description are the same as that of an outdoor unit, and the indoor unit is also the same as that of an outdoor unit that is improving every day.

  Next, FIG. 7 and FIG. 8 show an outline of a processing method in a waste processing facility such as a recycling center. ST01 when household appliances are disposed after being used in general households, etc., and waste products are first collected by public agencies such as city halls, specialized dealers handling discarded products, household appliance stores, product manufacturers, etc. The Waste products collected at specific locations are brought to the recycling center ST02. At the recycling center, used home appliances brought in as recycled products, such as electric appliances such as air conditioners, are disassembled and sorted by hand directly or using a tool in advance, ST03, and whether it is plastic is determined ST04. After that, for parts that are difficult to disassemble by hand, it is judged whether it is easy to sort, and materials are separated using a crusher and a sorter.

  For example, in the case of an outdoor unit, external components such as the service panel 108, the top panel 114, the front cover 102, the back panel 109, etc. are collected after recovering the refrigerant sealed in the refrigerant cycle such as the in-line piping portion of the compressor 105 of the outdoor unit. Disassemble by hand with a tool. In addition, electrical parts such as electrical parts are removed, and easily disassembled structural parts such as the fan 116, the motor support 113, the pipe assembly 110, the four-way valve 111, the compressor 105, the separator 104, and the heat exchanger 115 are manually removed. .

  For parts that are difficult to dismantle by hand, such as heat exchangers composed of copper and aluminum among the removed parts, use a crusher and a separator to separate copper and aluminum after manual disassembly. ST13 which performs work. Thereafter, the process is divided into recycling and disposal ST14. In addition, the plastic parts taken out in the manual dismantling stage are selected from plastic materials that can be easily separated based on the indication of the plastic material provided in advance in ST05. Further, when it is known that the plastic is a specific plastic, only the type of the plastic is collected for each part or based on the display of the part, such as a terminal block and a fan. For example, in an air conditioner fan, there is a case in which glass fiber or the like is mixed in plastic in order to maintain strength. Therefore, the extracted fan is stored separately from other parts ST06. The collected plastic is crushed and ST07, washed to produce ST08, recycled plastic is produced and ST09 is formed again on the outer part of the molded product, for example, the air conditioner ST10, and the surface of this molded product is painted on the ST11 product body. ST12 assembled as a part. In this way, the material of the used old equipment discarded can be reborn as a part of a new product, resources can be used effectively, and a very excellent technology as an environmental protection measure can be obtained.

In the case of indoor units, the installation plate 5, the front panel 4, the air filter 7, the corner box 6, the fan 9, the electrical component box 24, the fan motor 15 and the like are separated by manual dismantling, and the rest are crushers and sorting machines. To separate iron, copper, aluminum, plastic parts, dust, etc. The suction grill 4, which is a plastic part, is an exterior design part, so it is often painted on plastic. Plastic materials that have been painted normally become impurities in the recycling process and cannot be recycled. Therefore, the disposal process is performed except when the indication that recycling is possible is performed. In addition, the plastic parts taken out in the manual disassembly stage are selected and collected based on the indication of the plastic material provided on the parts in advance. When a specific plastic is known, for example, in a fan, there is a case in which glass fiber or the like is mixed in the plastic in order to maintain strength. Therefore, the taken-out fan is stored separately from other parts. Others that cannot easily sort out plastic parts are collected ST15 and discarded or used as fuel ST16.

  The idea of collecting specific plastics according to the present invention is to collect the used plastic parts of the predetermined equipment among the plastic parts collected from the used household appliances and disassembled / disassembled by the household appliance recycling factory. By separating and recovering, virgin plastic can be recovered by reusing the plastic material with almost uniform dirt and physical properties, simplifying the cleaning process, reducing the price of recycled plastic, and stabilizing physical properties. By making it possible to recycle parts with only recycled plastic without mixing, the utilization rate of recycled plastic is further increased. Examples of this include, for example, air conditioner fans and refrigerator vegetable cases. Alternatively, a part using a flame retardant and a part indicated as ABS may be collected. The contents of the recycling process after the collection of the specific plastic will be described with reference to FIGS.

As shown in FIG. 17, the fan 9 of the indoor unit is generally an axial fan. A metal shaft 41 necessary for rotating the fan is insert-molded together with the vibration isolating rubber 43 at both ends of the fan. The metal shaft 41 and the anti-vibration rubber 43 become foreign matters that are not plastic when the fan is recycled, and the mixing thereof leads to a reduction in the quality of the recycled material. Therefore, at the time of fan recovery ST21, it is necessary to remove the corresponding part, but the fan end has a disk-like plate shape, and is only connected to the fan body by a plurality of thin blades. Therefore, when the connecting portion between the end plate and the blade is hit with a hammer or the like, the connecting portion can be broken, and the portion including the metal and the vibration-proof rubber can be easily separated. In addition, if the fan clearly shows that it is to be broken and separated or a symbol that indicates the position to be beaten is written on the fan, the collecting operation is facilitated.

The fan collected in this way is first sent to a recycling process called ST22 for crushing the fan. In some cases, a balance piece 42 for correcting the eccentricity of the fan is provided on the main body of the fan. Since the balance piece is usually a metal, if it is directly turned to the recycling process, the quality of the recycled material is deteriorated and the screw is damaged in the recycled material extrusion process. Therefore, this also needs to be removed in advance, but a small amount can be obtained by installing magnets for removing metal foreign objects at the raw material inlet of the extruder for pelletizing the recycled material or the main part of the crushing device in the recycling process. Metal foreign matter can be removed. In order to enable removal with this magnet, it is necessary to use a material having magnetism for the balance piece.

  On the other hand, the foreign matter adhering to the fan collected from the used home appliances includes not only foreign materials joined to the fan since the manufacture of the air conditioner but also dust adhering to the fan surface during use of the air conditioner. These foreign substances adhering during use may be uniformly adhering to the fan surface, and it is effective to remove them by washing ST23. If the fan shape is used as it is, it becomes difficult to clean the inner surface of the fan, so it is desirable to pulverize the fan to a certain size. However, since it is not possible to expect a physical peeling action in the cleaning process if pulverized too finely, it is desirable to stop the pulverization to a size of several cm to 20 cm ST22.

  As described above, the selected metals such as iron, copper, and aluminum are delivered to steel manufacturers for a fee or free of charge, and each material is melted and regenerated for use in air conditioners and other equipment and devices. Reused. Regarding plastic parts, plastics currently used in automobiles, household goods, home appliances, etc. are polypropylene resin (PP), polystyrene resin (PS), acrylonitrile-butadiene-styrene resin (ABS), acrylonitrile-styrene resin ( AS) etc. are used according to their characteristics. Since various materials are mixed in the current recycling process, plastic parts that are of the same material and can be easily separated are separated and collected. To do. At this time, a large number of plastic colors may be mixed, and if they are made of the same material, separate collection is performed as much as possible.

Further, since there is a case where glass fiber or the like is mixed in plastic to maintain strength, such as a fan, the taken out specific plastic, for example, the fan is stored separately from other parts. Fans in air conditioners are parts that use relatively large amounts of plastic, but fans often use resin mixed with fillers such as glass fiber to ensure heat deformation and strength due to rotation. Often, the physical properties of plastics are different from those of other plastic parts. For this reason, until now it was discarded without being used as recycled plastic. In order to solve this problem, only fans whose physical properties and dirt conditions are almost uniform during dismantling work of the air conditioner at home appliance recycling factories, etc. The plastic material obtained here is removed and removed, and then regenerated, molded again into fan parts, and used as product fan parts. .

In order to obtain recycled materials from the collected plastic products, the collected plastic materials are pulverized, the crushed material is separated by removing light foreign materials using wind power, and foreign matter due to difference in specific gravity using liquid or water in the floating layer. In this order, the foreign matter in the crushed material is removed in the order of foreign matter selection using a centrifugal dehydrator, and the additive containing antioxidant is added to the amount of virgin material added to the crushed plastic after removing the foreign matter. In addition, it produces recycled plastic. In addition, the above-described cleaning process makes the properties of the plastic material close to that of the virgin material, keeps it in a category where there is no problem with quality, and does not need to perform the cleaning step until the design is improved. Extract the recycled plastic material while keeping it as low as possible. Additives are generally added, but if you collect specific plastics such as fans that have little difference in material characteristics and usage conditions, add virgin material in a predetermined amount without adding this additive. Thus, a recycled material with sufficient performance can be obtained. The recycled plastics at this stage are made of the same material, so the physical properties are similar to those of virgin plastics, but the recovered plastics are mixed with plastics of various colors. A plastic part having a free color tone cannot be obtained, and some foreign matter may be mixed to generate a muddy point in the design. On the other hand, the recycle coating ST10 described in FIG. 7 may be performed.

  In this embodiment, an example of disassembling / disassembling / sorting the air conditioner is shown, but plastic materials recovered from other used home appliances, automobile parts, household goods, etc. may be used. .

Next, a technique for using more recycled resin of the present invention will be described. In order to make more use of the recycled plastic obtained by collecting, it is a place where the amount of plastic used is large, and it is a place where it is easy to get dirty during use, which is the exterior design part of the indoor unit, suction grill, front panel, vane Using the recycled material from the recovered plastic, molding is performed. These parts are the parts that make up the air path of the air conditioner, so it is easy to get dirty among recovered plastic parts such as other household appliances. However, the indoor unit is mainly used for wall installation, but it is installed at the top, and there are many parts that can only be seen except for a small amount of dirt from the outside. Is difficult to identify and is suitable for use at low cost for recycled plastics.

  As described above, after disassembling and dismantling used home appliances at a home appliance recycling factory and removing foreign matter from the collected plastic material, heat that can be recycled into plastic parts molded using the resulting recycled resin material Paint using plastic paint. When this recycled plastic is used in home appliances, it is a part that is easily contaminated, and when it is used as an external part that hits the air passage of an air conditioner, color variations and foreign matter that are likely to occur in the recycled plastic By taking measures against problems such as turbidity caused by mixing, and using it for the outer shell parts of indoor units that use a large amount of plastic parts in the air conditioner, the utilization rate of recycled plastic can be increased. In addition, by using a thermoplastic paint that can be recycled as a recycled resin material, the recycled resin can be recycled again the next time it is discarded, further reducing the virgin resin usage rate and reducing the environment. It contributes to load reduction.

There is a thermoplastic coating material as such a recyclable coating material, and the exterior design portion is painted using this coating material. As a result, it is possible to use more recycled plastic materials that could not be used for appearance parts due to variations in color tone or foreign matters. In addition, since recyclable coating is performed, even if the product becomes waste again, it can be recycled again. Further, by displaying information indicating that recycling is possible, displaying material, indicating that recycled plastic is used, and the like, effective information is given when the material is discarded.

  When a thermosetting resin such as urethane is used as a paint, the cured paint does not melt even when reheated, and remains as a foreign substance that causes a decrease in strength, etc., simply by physically dispersing in the recycled material, that is, in the pellet. Therefore, an acrylic system that is a thermoplastic paint is desirable as a paint for plastic. When recycling waste, the recovered plastic molded product coated with a recyclable thermoplastic paint is pulverized, melted and re-pelletized. Using this material as a resin molding material, a resin molded product is molded. By making the product painted with recyclable paint after molding, the same pattern can be recycled again and the reuse rate can be increased. Even if it is a thermoplastic paint, since the material and the paint mix well when melted in the recycling process, for example, if the material is a polystyrene resin, the paint has a structure similar to that of the polystyrene resin. That is, a styrene-modified acrylic resin obtained by adding a styrene group to an acrylic resin is used.

  In addition, when painting on molded products molded from recycled materials, or when painting light colored plastic on dark colored plastics, it is necessary to consider thickening the coating or mixing the pigment with recycled plastic to make it whitish once. . When the recycled plastic is a crystalline resin such as polypropylene resin, pretreatment such as primer treatment is performed. Parts such as the wind direction vanes of indoor units can be seen from the outside, such as parts that can be seen from the outside, and suction grills, doors, covers, etc. that are external parts of the front can be seen from the outside. It can be used for many parts such as refrigerator internal parts.

  FIG. 9 shows a flow in the case of reuse from a vegetable case made of virgin material provided in the refrigerator to the service panel 108 of the air conditioner outdoor unit. First, ST30, which is polypropylene PP, is molded to produce a ST31 vegetable case, and ST32 is used as it is in a refrigerator ST33, which is recovered at the time of disposal after use ST34. The recovered plastic molded product vegetable case ST35 is pulverized and ST36, washed and then ST37 and melt-kneaded re-pelletized ST38 to obtain a recycled material. This is formed as a recycled material ST39 and ST40, further recycle coating is performed ST41, and an air conditioner service panel ST42. By reassembling this completed molded product into an air conditioner, the reused material will be used as part of the new product. Moreover, the recycling process of the present invention circulates the recycling process to the air conditioner service panel ST42 again by collecting the air conditioner service panel instead of the vegetable case and pulverizing ST36 at the time of disposal after using the air conditioner. You can make use of limited materials.

Next, FIG. 10 shows a flow of circulating the fan collected from the air conditioner indoor unit to the air conditioner indoor unit again. The indoor unit fan 9 of the air conditioner is formed by mixing ST50 with glass fiber mixed with styrene / acrylonitrile, ST51, and ST53, which is assembled into the air conditioner as part ST52. The used air conditioner is collected and ST54, the collected molded product ST55 is coarsely pulverized and ST56, washed and ST57, then finely pulverized again ST58, the metal is removed ST59, and the melt-kneaded repellet is ST60. By using this as the recycled material ST61 and mixing ST62 with the virgin material ST50 and molding ST51, a molded product ST52 as a fan is obtained again. When the discarded air conditioner is recovered in this way, the indoor unit fan is also recovered as a plastic molded part and reused. In this case, if the physical properties of the recycled plastic cannot be close to the characteristics of the virgin plastic, the virgin plastic can be mixed with the virgin plastic when producing the recycled plastic material or molding the plastic part. Recycled plastics close to the physical properties may be produced. By collecting the plastics of the predetermined parts of the predetermined equipment, it is possible to unify the plastic material, making it possible to bring the characteristics of the recycled plastic closer to the characteristics of the virgin material, without mixing virgin plastic. Even it can be used for products. In order to enhance the effect of removing the deposits on the surface of the fragments crushed in the flow shown in FIG. 10, they are crushed once and then washed, and then pulverized again to a size of, for example, several mm. If it is made finer than this, it becomes powder and is difficult to handle due to electrostatic adhesion or the like, which is undesirable from the work environment. The length of the fibrous material mixed in the fan is about several hundred microns, and the influence during pulverization has little to do with the strength. However, there is a possibility that the fibers may fall in the screw when passing through the extruder in the repellet process, and the process of molding the melted and kneaded material as it is stabilizes the quality.

Thus, the fans individually separated at the recycling center are subjected to a regeneration process using the separated fan materials. Fan plastic materials used in air conditioners collected by different manufacturers are mixed with glass fiber to improve strength and thermal expansion characteristics, and the types of fan materials are similar or almost the same. Similar things are used. Therefore, it can be reused by collecting the recovered fan molded product regardless of the manufacturer of the discarded air conditioner. If the regeneration process is performed with the separated and collected fans, characteristics relatively close to the physical properties of the virgin material can be obtained. Therefore, based on the dispersion characteristics of recycled plastic, fan regeneration can be standardized by selecting the mixing ratio of recycled plastic material and virgin material in advance. According to the survey results of the collected products, depending on the degree of cleaning in the cleaning process before recycling, considering the safety factor, it is sufficient to use recycled material in the range of 20 to 60%. Therefore, it is possible to increase the utilization rate of fans that have been discarded. Furthermore, it is more effective to give effective information for the next disposal by displaying the fact that the recycled material is used in consideration of the next disposal.

  Next, examples of notation and the like that promote the reuse of plastic molded products described so far with reference to FIGS. 11 to 14 will be described. FIG. 11 and FIG. 12 are examples of marks indicating the amount of recycled plastic used on product bodies, for example, indoor units. FIGS. 11 (a) and 11 (b) are marks on a plastic molded product. FIG. 11 (a) shows that this part uses recycled plastic PS and weighs 10 g, and can be repeatedly recycled. It shows that there is. FIG. 11 (b) shows that this part uses recycled plastic PS for 10% of the weight of the part and can be recycled repeatedly. In this way, all the parts that use recycled plastic in the entire product may be marked like this, or this labeling is made on major parts that are easy to collect and heavy, and product catalogs and instruction manuals Alternatively, the electronic information storage device, such as a tag attached to the product body, describes or stores data useful for disposing of the product, such as the part name, material, whether recycled plastic is used, and its weight. May be. In addition to notifying the parts that recycled plastic was used for the product, if further details are required, the weight of recycled plastic used in each part, the mixing ratio of recycled plastic and virgin materials, etc. It is also possible to perform display showing.

  12 (a), (b), (c), (d), and (e) are not attached to the parts described above, but the product body uses a direct mark to indicate that the product uses recycled plastic. FIG. If the product main body is an air conditioner, it is easy to see if the indoor unit and outdoor unit are displayed separately, and it is convenient for disposal. The name plate itself or the name plate may be written at the same position, or it may be attached to a position that is noticeable when the cover or door is opened. FIG. 12A shows that a product having this notation uses 100 g of recycled plastic by weight. FIG. 12B shows a mark indicating the usage rate of recycled plastic in the product. This product explains that 1000 g of plastic parts are used in this product, and 300 g of recycled plastic is used. In this way, for example, the result of the environmental protection measure becomes visible by the notation of the reproduction PL usage rate of 30%. On the other hand, it is also possible to display the results in a ranking that is a guideline for environmental protection activities without directly indicating the percentage. In FIG. 12 (c), since it is 30% or more, the AAA rank is shown as the best rank. When plastic parts have a structure that is difficult to disassemble directly at the time of product disassembly, or when they cannot be disassembled together with purchased parts like lead wire insulation, many problems remain, such as when the disassembly cost is very bad with too small parts It is conceivable that the relationship between the percentage and the rank symbol differs for each product. In FIG. 12D, 1000 g of plastic parts are used in the product, and 100 g of recycled plastic is used in the product, so that it is indicated by a rank symbol AA which is a guideline for a reuse rate of 10-30%. FIG. 12 (e) is an example of a mark to be written on the product, and is a mark symbol indicating how much this product contributes as an environmental measure, which is a standard for using recycled plastic. Not only symbols, but also energy saving rank symbols, numerical values indicating the results, symbols indicating contributions such as low toxic substances and their contents, etc. are described.

  In addition, as in FIG. 11, the mark is not directly engraved, but the product catalog, instruction manual, electronic information storage device such as a tag attached to the product main body, or the product is registered by being readable in the database via the Internet. It is also possible to disclose the material reuse state of the main body. As shown in FIGS. 11 and 12, electronic information such as a mark on the product main body or an incorporated part as a mark, or a name plate attached to the main body, or an attached name plate-like IC card, etc. Information disclosure means for publishing material information such as reusable parts of products, usage conditions of recycled materials, such as storing in a storage device or registering in the database with only information for accessing the Internet on the main unit It can promote environmental measures. Kinds of items that are useful for promoting the use of recycled plastics and environmental measures for the entire product, such as the amount of recycled or reused metals other than plastic, the amount of reuse, the amount of energy used, the degree of use of hazardous substances, etc. It is also possible to describe and store important material data and data related to energy saving, and to make the product information transparent to the environment transparent so that it can be used for environmental measures.

That is, the present invention relates to a part or a major part of parts using recycled plastics in home appliances such as air conditioners and automobiles using parts molded from recycled plastic materials obtained from recovered plastic parts. Indicate that recycled plastic material was used, and indicate the total weight of recycled plastic used in the entire product or the ratio of recycled resin material in the total weight of plastic parts on the main unit, or catalog. Information on the environment of the product, for example, the total weight of the recycled plastic material used, or by storing it in an electronic data storage device such as a tag attached to the main body or registering it in a database, etc. Whether it is a third party, that is, a user, Anyone, whether it is a person or a public institution, can make confirmation of the product environment information, that is, manufacture of home appliances such as air conditioners, automobiles, etc. regarding product environment information, that is, the usage rate of recycled plastics, etc. Fair and fair competition among suppliers is possible, and based on competition among manufacturers, it is possible to accelerate environmental improvement activities such as recycled plastic utilization rate across the entire manufacturer. In the present invention, the amount of recycled plastic used or the usage rate is taken up as a guideline for material reuse. However, for example, a simple one that recycles and uses metal has already been implemented considerably. Although it is a material that can be easily used for any product, many types of materials are progressing day by day, and the conditions for regenerating the materials are difficult in various ways. Although it is abandoned or burned as dust, the present invention has developed a system for transparentizing information on environmental improvement activities of products as a countermeasure for this, and is useful for environmental protection and burns. This eliminates the waste of resources. Of course, it goes without saying that display of marks, description of numerical values, storage, etc. are also effective as environmental measures for other materials.

  As described above, if recycled plastic is reused in products, the utilization rate of recycled plastic can be greatly increased. Since this improvement in the utilization rate of recycled plastic can be utilized as information for product selection at the time of purchase by a product purchaser, as explained in FIG. 12, the total weight of recycled plastic used in the entire product or Indications indicating the ratio of the total weight of recycled plastic parts to the total weight of the product or the ratio of the total weight of recycled plastic used to the total weight of the plastic parts used in the product, etc. The product environmental information is made transparent by attaching it to the product as a printed matter that can be confirmed by a third party, or as electronic data that can be read out, or making it public in a database. In order to make it easy for any user, other company, third organization, etc. to confirm the display of the weight and utilization rate of recycled plastic for this product as a whole, all or all major parts using recycled plastic are It is good to display like 11.

  By displaying, describing, or storing such data, anyone such as a user, another company, or a third institution can perform a validity verification evaluation on the recycled plastic utilization rate of the entire product. For example, when the display is as shown in FIG. 11 and FIG. 12, the other company or the third organization that conducts the inspection disassembles the product and displays it based on the display indicating that recycled plastic is used. Collect all the parts that were made. Next, when the mixing ratio of recycled plastic and virgin material is described in each part, measure the weight of each part and calculate the amount of recycled plastic used for each part from the mixing ratio. . Similarly, the weight of recycled plastic is obtained for each part using recycled plastic, and the total weight of recycled plastic used in the entire product is confirmed. It is possible to easily verify whether or not the total weight of the recycled plastic inspected in this way is appropriate with the total weight of the recycled plastic described in the main body. In addition, it is not necessary to display the display indicating that the plastic is provided for each part on all parts, and the third institution or the like can perform a certain verification evaluation only by displaying only the main parts.

  As described above, by displaying for each part that uses recycled plastic and noting the usage rate of recycled plastic for the entire product, it is possible to verify and evaluate the usage rate of recycled plastic by other companies and third parties. This enables fair and fair operation of the recycled plastic usage rate among manufacturing companies, and further accelerates the improvement of recycled plastic usage rate. It can also be used as environmental improvement activity information for product selection. Furthermore, in order to convey the information for product selection at the time of purchase to the product buyer in an easy-to-understand manner, according to the recycled plastic usage rate, as already explained, a display with a rank symbol etc. with a clear use rank or a label, etc. In addition, it is possible to accelerate activities to improve the utilization rate of recycled plastic. In addition, if you provide information to the product purchaser by using labels, etc. that indicate a reduction in the environmental impact of the entire product, including items that contribute to environmental considerations such as energy conservation and non-use of hazardous substances, etc. In addition to accelerating the improvement of the recycled plastic utilization rate, it is possible to accelerate the overall environmental improvement activity information on items related to environmental load reduction.

  FIG. 13 and FIG. 14 illustrate an example of the notation of the display board on the product related to the entire environmental improvement activity information related to environmental load reduction, taking an improvement in the recycled plastic utilization rate as an example. FIG. 13 is a display example showing a small amount of recycled plastic for each part that uses recycled plastic mainly for internal structural parts of the indoor unit. FIG. 14A is shown on the exterior part of the indoor unit and is used for the indoor unit and the outdoor unit. It is a figure which shows the gross weight notation of the reproduction | regeneration plastic which is. FIG. 14B is a diagram illustrating the notation of recycled plastic for each part in the outdoor unit. The notation 201-207 for each part describes a triangle mark indicating that the part material can be used repeatedly, an indication that the part is recycled plastic, and the weight of the part. In addition, a notation 200 indicating the weight of the recycled plastic of the entire product describes a triangle mark indicating that the recycled plastic used can further use the material repeatedly, and the total weight of the recycled plastic.

  As described above, used household appliances are dismantled and collected from waste disposal companies, etc., and the plastic materials obtained here are collected, molded into plastic parts using the recycled plastics obtained here, and this recycled For products with synthetic resin using plastic parts, measure the total weight of recycled plastic used in the entire product, or the ratio of recycled plastic used in the entire product to the total weight of the product, or An indication of the proportion of recycled plastic used in the entire product in the total weight of plastic parts can be written on the main unit, printed on catalogs, instruction manuals, etc., or electronic data can be inquired on the main unit of the product or the Internet Since it was written in a way that anyone could check, such as memorizing things, Sakai improvement activities rises can social systems and systems which significantly advance the are transparent environmental improvement by the public of product environmental information.

  In addition, the above explanation mainly explained the structure of the air conditioner outdoor unit and the indoor unit, but the explanation was mainly about the case of the air conditioner. However, it is a product that uses plastic and uses recycled resin. Needless to say, it can be applied to all devices. For example, structural parts that use recycled plastic as a strength element, electrical parts that are insulation parts, parts that are used parts such as storage, parts that are heat insulation parts, refrigerators as home appliances, televisions, washing machines, vacuum cleaners, etc. Of course, it can be applied to all trains and office equipment. The total weight of recycled plastic in air conditioners is shown in an example where the indoor unit is easy to see and avoids the position where the wind is blown directly, and it is installed in a place with little dirt, but this mark is attached to the back of the refrigerator door. It is recommended that the rear side of the bonnet of the automobile, the handle part inside the door, the internal vehicle number attachment part of the vehicle, the personal computer, the printer, etc. be installed at a position where it is easy to see and has little dirt.

  In the present invention, the example of using the recycled product in the method of melting the collected plastic and molding it to the next product has been explained. Next, the product was recovered from the product discarded as a part other than the plastic of the product body or device. An example of reuse when used as is or with only slight care will be described. When the collected products are reused, parts that satisfy parts that do not require designability, parts that are not in a corrosive environment, parts that are easy to remove, etc. are collected from the used products. The metal parts selected and collected from the used products in this way are the sheet metal lid of the refrigerator back substrate and the caster of the refrigerator, or the resin parts to be collected are transparent shelves used for partitioning in the cabinet, etc. Even when these reusable products are used, it is effective to attach the notations described with reference to FIGS. 11 to 14 and disclose them as information on environmental improvement activities.

  As an example of a part that can be reused as it is as described above, an example of selecting, collecting, and collecting a specific part when reproducing from a discarded product has been explained, such as a fan that has already been described. It is also effective to collect specific parts. Next, a description will be given of collecting and reusing a specific part used at a specific location in a product type such as a pre-selected home appliance. When dismantling used home appliances, etc., the work to remove screws etc. is done manually.For example, after removing the outer shell surface of the indoor unit or outdoor unit, the part that is not the internal air passage, and further around the water system Screws that have been placed and used in different parts have little deterioration and should be collected separately. Collected metal screws have little dirt and little corrosion, so they are first returned to the home appliance manufacturer for a fee or free of charge. The manufacturer can effectively reuse this screw as a recycled screw. The method of using this screw will be described with reference to FIGS.

  For example, in the case of a screw part or an air conditioner that is fixed when transporting home appliances, there is a case where both are fixed with screws before the indoor unit body and the installation plate are packed. These screws are fixed with screws for the purpose of improving workability during packing and unpacking, and to prevent the main body from being damaged by the mounting plate due to vibration during transportation. Even if dirt, rust, etc. are generated, the function can be sufficiently satisfied, so that the recovered screw can be effectively reused. FIG. 15 shows an example of using this recycled screw, that is, a screw that is recovered and reused. When shipping a new product, the main body of the indoor unit 30 is covered with side cushions 31 that are packing materials on both sides, and the remote controller 32 and the instruction manual 33 that are accessories are stored inside the indoor unit main body. In this case, the stored remote controller is suppressed by the installation plate 5 for fixing the indoor unit 30 to the wall surface of the room, but this installation is performed by using the recycled screw collected in the screw hole provided on the indoor unit main body side by making a hole in the installation plate. What is necessary is just to fix a board to a main body. FIG. 16 shows the assembled state after transportation. This recycle screw is not necessary at the time of installation, is only used at the time of transportation, and can be used again as it is. In addition, if marking or painting that indicates a reused part of a reused screw, such as red, which means a reused product, is performed on the screw head or the entire surface, a new screw will be created at the time of manufacture and installation. The effect which prevents mixing with is acquired.

  In addition, the plastic cap attached to the end of the extended refrigerant pipe connecting the indoor unit and the outdoor unit can also be recovered as a specific part and reused. This plastic cap is attached to the pipe end of the extension pipe in order to prevent dust and moisture from entering the pipe. Since the plastic cap removed when the indoor unit was installed was not exposed to the outside air, there was almost no deterioration, and it could be collected separately, and the manufacturer could effectively reuse the plastic cap.

  Furthermore, when the composition ratio of reuse parts increases in the future, it is required to identify whether the part is a virgin product, a reuse product, a non-reusable product, or a reusable product. In that case, the difference can be identified in advance by attaching a mark to a reusable part when the target part is manufactured. Thereby, the mark written on the part in the recycling process can be confirmed, and it can be easily determined and sorted whether the product is non-reusable or reusable.

  Furthermore, by embedding or attaching an IC tag to a component part, it is possible to read the material name, use history, and return destination manufacturer name of the part and classify them for the purpose of separate collection, recycling, and reuse. For example, as shown in FIG. 18, after the disassembling process of ST70, the information of the IC tag is read in ST71. Based on the information on whether or not reuse is possible in the IC tag information, it is determined whether or not reuse is possible in ST72. If possible, it is returned to the manufacturer in ST75 in order to evaluate and confirm whether it can be reused finally. On the other hand, if it is determined in ST72 that reuse is not possible, it is determined in ST73 whether or not recycling is possible. If recyclable, proceed to ST76 recycling process. If it is determined in ST73 that the product cannot be recycled, it is determined in ST74 that the product cannot be recycled, and the process proceeds to the disposal / incineration process in ST77.

  Also, for the purpose of improving reusability, for example, in a power plug cord, it is molded with a material in which a photocatalytic material is kneaded into the cord coating, or a photocatalytic material is applied to the coating surface, and dust and dirt are difficult to adhere, or Reusability can be improved by making it easy to wipe off dust and dirt. Further, in the refrigerant circuit parts such as the stop valve, the reusability can be improved by adopting a structure in which oil and dirt (sludge) remaining inside when removed are easily cleaned by ultrasonic cleaning or the like.

  As described above, the present invention disassembles and disassembles used home appliances at a home appliance recycling factory, removes foreign matter from the collected plastic members, and recycles the plastic parts molded using the recycled resin material obtained here. By coating with possible thermoplastic paint, it can be used repeatedly, and the range of use can be expanded to exterior design parts such as suction grill parts for indoor units and vane parts that control the wind direction. The plastic reuse rate can be improved.

  The present invention collects used home appliances as described above, and is a part that is easy to collect a predetermined device among plastic parts and metal parts that have been disassembled and dismantled at a home appliance recycling factory, Since parts of a predetermined shape or parts at predetermined locations are collected and reused or plastic parts are recycled, it is possible to carry out economically efficient activities in the recycling process. In particular, collecting plastic fan parts, removing the foreign material from the plastic material obtained here, recycling it, molding it into fan parts again, and using them again as fan parts has the effect of increasing the reuse rate. large. When the plastic fan is collected, the foreign material can be easily removed by scraping the dissimilar material joining portion with a hammer or the like and then collecting only the desired plastic portion. Furthermore, if the balance piece provided in the plastic fan is made of a magnetic material, repeated reproduction can be easily performed.

  As described above, in the recycled plastic part, the present invention performs a display indicating that the recycled resin material is used, a display indicating the weight using the recycled resin, or a display indicating the mixing ratio of the recycled resin and the virgin resin. Can show the results of environmental activities to anyone, and it is very effective as an environmental protection measure. For example, disassemble and collect used home appliances from a waste disposal company, collect the plastic material obtained here, and use the recycled plastic obtained here to mold it into plastic parts. The total weight of recycled plastic used in the entire product, or the ratio of recycled plastic used in the entire product to the total weight of the product with the synthetic resin used, or the plastic parts of the entire product It is advisable to indicate the ratio of recycled plastic used in the entire product as a percentage of the total weight on the main unit, or in a way that can be confirmed by a third party, such as printed materials such as catalogs and instruction manuals. In addition, if a product with synthetic resin using recycled plastic parts is displayed indicating that recycled resin material has been used for all or all of the parts using recycled plastic, When all the used parts or the main parts indicate the indication that recycled resin material was used and the weight of recycled plastic used for each part or the mixing ratio of recycled plastic material and virgin material, Three-party evaluation can be performed easily.

  In addition, a resin molded product using a molded product using a recycled resin material obtained from a plastic member obtained by disassembling or dismantling a used product, which is a part of the product of the present invention, as a design component or an external component, The molded product is thermoplastically coated with a thermoplastic resin that is compatible with the recovered plastic member or has a structure similar to the recovered plastic member, and can be reused again. It is good to add a styrene group to the thermoplastic resin to the recovered plastic resin polystyrene resin, and to the recovered plastic member crystalline resin such as polypropylene resin is subjected to primer treatment before the thermoplastic coating. Good to do.

  As described above, the present invention recycles plastic members collected from discarded home appliances into molded material, and at least a part of the air conditioner fan, grill component, vane component, etc., using the recycled material. The parts that can be seen from the outside or parts that can be seen from the outside by opening and closing the doors of refrigerator cases, shelves, etc. are molded, and the recycled material does not add additives, so the recycling process is simple and reliable can get. However, fans that are recycled molded products are molded from parts that are collected from discarded plastic fans and mixed with glass fiber. When mixed with recycled material and molded, a product with stable performance such as strength can be obtained.

  In the manufacturing method of the present invention, the parts, which are plastic members that have been disassembled or disassembled and recovered, are crushed and washed into a recycled material, and after molding the recycled material, the molded product is made of a thermoplastic resin compatible with the recycled material. When the coated and molded product is used as a design part or an exterior part of a home appliance, the recycled material can be manufactured with a wide range of use and an inexpensive part by adding no additive.

  In the present invention, a recovered plastic member is crushed and washed to make a recycled material, and the total weight value of the molded product or the total weight of the molded product in the main body using the molded product molded using the recycled material is the main body. The ratio of the total weight of plastic parts, or the ratio of the total weight of the molded product to the total weight of the main body is indicated on the main body, or printed on catalogs, instruction manuals, etc. attached to the main body, or on the main body. Information relating to environmental measures can be made known thoroughly by storing the information in an electronic recording medium such as an attached tag so that the information can be read out or making the stored information public on the Internet or the like.

  As described above, according to the present invention, used home appliances are disassembled and disassembled by a home appliance recycling factory, and the collected plastic material is removed to remove foreign substances, and then recycled into plastic parts molded using the obtained recycled resin material. By painting using a possible thermoplastic paint, and by using this recycled plastic for external parts that are easily contaminated when used in home appliances, such as air conditioner air passages. Measures for problems such as color variation and clouding point caused by foreign matter, which are likely to occur in recycled plastics, and is used for the outer shell parts of indoor units that use a lot of plastic parts in the air conditioner. It is to increase the utilization rate of plastic.

  Furthermore, by collecting used home appliances and separating and disassembling predetermined plastic parts from plastic parts that have been disassembled and dismantled by a home appliance recycling factory, the state of dirt and physical properties can be improved. Recycling with an almost uniform plastic material simplifies the cleaning process, reduces the price of recycled plastic, and stabilizes its physical properties, so that parts can be made using only recycled plastic without mixing virgin plastic. By making it possible to recycle, the utilization rate of recycled plastic is further increased. In addition, by using a thermoplastic paint that can be recycled as a recycled resin material, the recycled resin can be recycled again the next time it is discarded, further reducing the virgin resin usage rate and reducing the environment. It contributes to load reduction.

  In addition, in the present invention, in the home appliances such as an air conditioner, the next component with the largest amount of plastic is a fan. However, the fan is not limited to a filler such as glass fiber in order to ensure deformation due to heat and strength by rotation. Since mixed resin is often used, the plastic properties are often different from those of other plastic parts. For this reason, it is discarded without being used as recycled plastic. To solve this problem, home appliance recycling factories only sort fans that have almost uniform physical properties and dirt, and are easy to identify and separate in the dismantling process during dismantling work such as air conditioners. Collecting and removing the foreign material from the plastic material obtained here, recycling it, molding it into a fan part again, and using it as a fan part of a product, thereby improving the utilization rate of the recycled plastic.

  In addition, the present invention uses a recycled plastic material for a part or a main part of a part using a recycled plastic with respect to a product using a part molded from a recycled plastic material obtained from a collected plastic part. The indication of the total weight of recycled plastic used in the entire product or the ratio of recycled resin material to the total weight of plastic parts is indicated on the main unit, or in printed materials such as catalogs and instruction manuals. By providing the notation, it is possible for third parties to verify the total weight of recycled plastic materials used in products, or the proportion of usage. It becomes possible to compete fairly and evenly between the equipment manufacturers, and based on the competition among the manufacturers, It is to allow to accelerate the improvement activities utilization throughout the manufacturer.

  As described above, the present invention discloses product environment information such as recycled materials used in the product main body such as home appliances, reused parts, etc. to the product main body and discloses so that anyone can evaluate the product environment information. It is intended to further activate environmental measures by a system that publishes specific data from which the obtained product environment information can be obtained.
