Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in loading efficiency at the time of transportation, especially when recycling large home appliances such as refrigerators.

[0002]

2. Description of the Related Art In recent years, attention has been paid to disposal of large home appliances such as refrigerators and washing machines as interest in global environmental problems increases. In particular, refrigerators include chlorofluorocarbons (hereinafter referred to as CFCs) in urethane insulation and in refrigerants
Since it causes environmental problems such as ozone layer depletion and global warming due to the influence of air, proper recovery of CFC11 and CFC12 is necessary. In particular, the CFC11 foaming agent used for the heat insulating material of the refrigerator is not easy to recover the foaming agent because the foaming agent is contained in the fine closed cells of urethane, so it has to be transported to a specific collection facility. Was.

[0003] According to the report of the Industrial Structure Council of the Ministry of International Trade and Industry, manufacturers are obliged to collect and recycle large refrigerators, washing machines, TVs and videos from 2001,
In particular, it is desired that a large refrigerator can be efficiently transported.

Japanese Patent Application Laid-Open No. 4-340079 proposes a refrigerator in which a refrigerator room installed above, a freezer room and a vegetable room installed below can be separated, and a cooling unit can be separated.

[0005] Further, Japanese Patent Application Laid-Open No. 7-294097 has already filed an application in which a refrigerator is unitized and a connecting member is provided to enable easy disposal and recovery by material.

However, the life of a refrigerator varies depending on the time of purchase and the state of use, so that products of the same manufacturer are not always discarded at the same time. When mixing with refrigerators of other manufacturers and so on, the processing method by removing the above-mentioned connecting part causes a problem that it takes time for sorting if it is to be used effectively, and if the separation method differs between manufacturers, It is necessary to master the work, and even if mastered, there is a drawback that the work efficiency is reduced by the difference in the separation work.

[0007] Therefore, in order to reduce the cost of disposal, it is desired to treat the refrigerator without depending on the product release time or the difference between manufacturers.

[0008] Transporting a used large refrigerator to a specific CFC recovery facility without dismantling it as a product requires a great deal of energy and a large number of trucks and manpower both in terms of weight and volume. As a result, there is a problem that recycling is difficult to proceed even if there is a need from global environmental problems.

Hereinafter, a conventional disposal process of a large refrigerator will be described with reference to the drawings. 9 and 10, reference numeral 1 denotes a conventional refrigerator, which includes a refrigerator room 2 in an upper stage, a first freezing room 3, a second freezing room 4 in a middle stage, and a vegetable room 5 in a lower stage. The main body of the refrigerator 1 is composed of an upper
And a lower body 7 including a first freezer compartment 3, a second freezer compartment 4, and a vegetable compartment 5. 8 and 9 are double doors provided on the entire surface of the refrigerator compartment 2. Reference numeral 10 denotes a ceiling surface plate of the lower main body 7, which is made of a rigid flat plate made of metal or the like. 11
Is a cool air outlet provided behind the ceiling face plate 10 of the lower body 7, and 12 is a cool air return port. 13 is the lower body 7
Mounting protrusions provided at four corners of the ceiling face plate 10. Reference numeral 14 denotes a lower bottom plate of the upper body 6, which is made of a flat plate having rigidity such as metal. Reference numeral 15 denotes mounting recesses provided at four corners of the lower bottom plate 14 of the upper body 6.

Reference numeral 16 denotes a cooling unit. 17 is a compressor, 18 is a condenser, 19 is an evaporator, and forms a cooling unit 16 together with a capillary (not shown) and a fan (not shown).

[0011] Regarding the refrigerator configured as described above,
The operation will be described below. In the factory, upper body 6 and lower body 7
Are separately prepared, transported separately to the upper body 6 and the lower body 7 during transportation, and are finally installed in a kitchen, a dining room, or the like at home. That is, the upper body 6 is installed on the lower body 7, and the refrigerator 1 is fitted with the mounting projection 13 and the mounting recess 14.
To form At the time of installation, the upper body 6 and the lower body 7 may be fixed with mounting hardware or the like.

Then, the installation is completed and the cooling unit 1
When the operation of 6 is started, the compressor 17 rotates, the compressed refrigerant releases heat in the condenser 18 and liquefies, and then evaporates at a low temperature in the evaporator 19. At this time, the surrounding air is cooled to generate cool air. The generated cool air is sent by a fan to the first freezing room 3, the second freezing room 4, and the vegetable room 5 provided in the lower body 7, and cools each room to an appropriate temperature. A part of the cool air passes through the cool air outlet 11 to cool the refrigerator compartment 2 and then returns to the cool air return port 1.
2 returns to the cooling unit 16.

[0013]

However, in the above-mentioned conventional structure, the refrigerator 1 is simply disassembled into the upper body 6 and the lower body 7 at the time of disassembly, so that the individual handling is improved. However, CFC11 and C contained in urethane insulation and refrigerant
When transporting to a specific recovery facility for proper recovery of FC12, the total number of refrigerators that can be loaded on transportation means such as trucks was the same, and as a result, air was transported. Therefore, the problem of carbon dioxide generated from the oil consumed was also not negligible.

Further, since the lower body 7 has the ceiling plate 10 and the upper body 6 has the lower bottom plate 14, the number of seals is increased as compared with a normal refrigerator. For this reason, there is also a disadvantage that the performance of the heat insulating material is greatly deteriorated due to the invasion of moisture or the like from the seal portion, resulting in an increase in power consumption.

Further, the size of the refrigerating compartment 2, the first freezing compartment 3, the second freezing compartment 4, and the vegetable compartment 5 is restricted due to the restriction of the surface divided into the upper body 6 and the lower body 7, and the evaporator is not limited. There are disadvantages that the installation position of the 19 is limited and a necessary internal volume cannot be secured, and that cooling unevenness easily occurs.

An object of the present invention is to solve the conventional problem, and an object of the present invention is to provide a refrigerator having an improved loading efficiency when transporting the refrigerator to a specific collection facility when the refrigerator is discarded.

It is another object of the present invention to provide a refrigerator in which the infiltration of moisture and the like from the seal portion is reduced and the performance of the heat insulating material is less deteriorated.

It is a further object of the present invention to provide a refrigerator having a high degree of freedom in designing a partition surface that can be set arbitrarily and hardly causing uneven temperature.

[0019]

In order to achieve the above object, a refrigerator according to the present invention is characterized in that a refrigerator box previously divided into two equal parts at a collection base is transported in combination with each other, and the cut-out portion is subjected to design processing. The line is inserted.

According to the present invention, the total number of refrigerators that can be loaded on a transportation means such as a truck is about 2 when transporting to a specific recovery facility in order to properly recover the CFC 11 contained in the urethane insulating material. Can be doubled.

In the refrigerator of the present invention, the refrigerator boxes previously divided into two equal parts at the collection site are transported in combination with each other, and only the iron plate-like outer box of the refrigerator box is cut off, such as plastic or laminated foil. It is made of easy-to-cut material.

This eliminates the need to cut the iron plate, which is the outer box material of the refrigerator box, and easily divides the refrigerator box into parts other than a specific waste disposal company without using a large cutting device. can do.

Further, it is another object of the present invention to provide a refrigerator which has a high degree of freedom in changing the internal volume of the refrigerator and in designing the refrigerator and is less likely to cause uneven temperature because the cutting position can be set arbitrarily.

It is characterized by having a cut-out line that has been subjected to design processing in the part, and when transporting to a specific collection facility in order to properly recover the CFC 11 contained in the urethane insulation, transportation means such as a truck This has the effect of increasing the total number of refrigerators that can be loaded in a refrigerator approximately twice.

According to a second aspect of the present invention, in order to improve the loading efficiency at the time of transportation, the refrigerator boxes divided in advance at the collection base are transported in combination with each other, and the refrigerator box is made of an iron plate. The box is made of an easy-to-cut material such as plastic or laminate foil only for the cut-out part.There is no need to cut the iron plate, which is the outer box material of the refrigerator box, and a large-sized cutting device is used. Without this, the refrigerator box can be easily bisected even by a company other than a specific waste disposal company. Furthermore, since the cutting position can be set arbitrarily, the internal volume can be changed, the degree of freedom in design can be increased, and the temperature can be prevented from becoming uneven.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same components as those in the related art are denoted by the same reference numerals, and detailed description is omitted.

When transporting to a specific recovery facility for proper recovery of C11, the total number of refrigerators that can be loaded on the transportation means can be approximately doubled. That is, high-density loading is possible, and as a result, air is not carried. Therefore, the amount of carbon dioxide generated from petroleum consumed for transportation per vehicle can be halved.

In the present invention, the iron-made outer box of the refrigerator box is cut into an elliptical shape, and an easily cut material such as a plastic film or a laminated foil is adhered from the back side of the outer box. The outer box may be formed by connecting using an easily severable material such as a plastic film or a laminated foil and foaming the heat insulating material.

It is conceivable that a very small amount of CFC 11 may leak during cutting in the first and second embodiments. However, by setting the room to be cut to a negative pressure or collecting from below the room, the global environment can be reduced. Impact on the environment can be minimized. Regarding leakage during transportation, it may be wrapped in a plastic bag or the like, or transported in a highly sealed container.
