Abstract: PURPOSE:To facilitate separating and decomposing processes at the time of exhausting and to expedite recyclizing of a material by incorporating a foamed heat insulator between an inner box and an outer box, and interposing a mold release sheet between the inner, outer boxes and the insulator. CONSTITUTION:A heat insulation box used for a refrigerator, a display case, etc., is formed by incorporating a foamed heat insulator 4 between a plastic inner box 2 and an outer box 2 brought into contact with an iron plate, and comprises a mold release sheet 5 interposed between the inner, outer boxes 2, 3 and the insulator 4 on the entire surface. As the sheet 5, a paraffin sheet, a PVC sheet, a PP sheet, a PE sheet, etc., having no adhesive properties with the insulator 4 is used. The box 2 is covered on its outside with the sheet 5 before the insulator 4 is injected, and the sheet 5 is inserted along the inside of the box 4. When the boxes 2, 3 processed in this manner are engaged, the sheet 5 is simultaneously caulked to be assembled.

Abstract: PURPOSE:To bond a cap door with a urethane insulation material firmly and enhance structure strength by planting hair all over the surfaces which come in contact with the urethane insulation material of the resin-made cap door in the U-shaped cross section. CONSTITUTION:An insulation door comprises a door front iron sheet 3, a U-shaped cross section cap door which is injection-molded with Freon 123-resistant resin or Freon 141b resistant resin and an urethane insulation material 6 which uses as a foaming agent Freon 123 or Freon 14b integrally expanded in a box-shaped space comprising the cap door 7 and the iron sheet 3. After a bonding agent 10 is applied to the whole surface which comes in contact with the insulation material 6 of the cap door 7, there fixedly adheres a planted air surface 9, which comprises natural fiber and chemical fiber-made short fiber according to an electric hair planting process. The penetration of the planted hair into the insulation material 6 makes it possible to bond the insulation material 6 with the cap door 7 based on the anchor effect physically and powerfully as well.

Abstract: PURPOSE:To prevent the formation of rigid polyurethane foam of low density and low compression strength by providing a door front iron sheet and a reinforcing plate made of an insulated iron sheet and expanding integrally a rigid polyurethane foam insulating material in a box-shaped space between the door front iron board and the reinforcing plate. CONSTITUTION:In the door of this refrigerator, a reinforcing plate 3 is covered with a rigid urethane foam-made insulation material 6 where a rigid polyurethane foam insulation material 4 is integrally expanded in a box-shaped space which comprises the reinforcing plate 3 covered with the insulation material 6 and a door front iron sheet. The reaction heat of the rigid polyurethane foam 4 is arranged not to hinder the formation of foams of the rigid polyurethane foam insulation material 4 even near the reinforcing plate 3 since this construction reduces the heating value absorbed by the reinforcing plate 3 cut off by the rigid polyurethane foam insulation material 6. More specifically, this construction prevents the formation of low density and low compression polyurethane foam and provides a favorable outside view.

Abstract: PROBLEM TO BE SOLVED: To suppress deterioration with the elapse of time while reducing power consumption in a gas sensor for detecting the concentration of gas on the basis of a change in the electric resistance of a responsive part. SOLUTION: A heater 5 for compensating the heating of a responsive film 3 is added to the gas sensor 1 and the supply of power to the heater 5 is changed in a gas detecting case and a case not detecting gas by a heater drive circuit 9. The lowest power is applied to the heater so that the surface of the responsive film 3 is set to temperature generating no dewing not only to suppress dewing or deterioration due to a temperature rise but also to reduce power consumption.

Abstract: PROBLEM TO BE SOLVED: To provide a refrigerator which previously informs a user of freshness of a vegetable before damage thereto becomes further severe when the freshness of the vegetable is deteriorated. SOLUTION: There is provided an atmosphere sensor 24 in a vegetable chamber 12 for sensing a change in concentration of a composite gas component including gas component produced from an article contained in the change and gas components flowing from the outside of the chamber. On the basis of an electric output of the atmosphere sensor 24 a storage state of the contained vegetable can be checked without opening a door 14 with the aid of display means 30 and /or sound informing means 31 for displaying external appearances of vegetables and fruits, and hence it can be stored in the interior of the vegetable chamber 12b without corrosion thereof.

Abstract: PROBLEM TO BE SOLVED: To reduce the excessive amount of volatiles thereby to reduce an irritating odor when the temperature in a refrigerator rises by setting a gelatinous antibacterial agent, wherein a volatile antibacterial component is wrapped in a cyclodextrin, in an area where cold air passes. SOLUTION: A gelatinous antibacterial agent 14, wherein a volatile antibacterial component 13 is wrapped in a cyclodextrin, is set in an area such as a cold air duct 11 within a refrigerator where a cold air passes. If the moisture in the air gets into the refrigerator from the outside when a door thereof is opened, antibacterial component particles wrapped in cyclodextrin are released by being replaced with the incoming moisture. Thus, even if the temperature in the refrigerator rises when a door thereof is opened, the antibacterial particles in unnecessarily large amount are not released, and hence an irritating odor can be reduced, while smell reducing effects are being sufficiently maintained.

Abstract: PROBLEM TO BE SOLVED: To maintain the antibacterial constitution concentration in a container constantly and to obtain a high antibacterial effect including air and food surface by arranging a sustained release film for discharging an antibacterial constituent made of olefin resin at a volatile antibacterial material at a part where a cool air passes in a refrigerator. SOLUTION: A sustained release film 12 for discharging an antibacterial constituent made of olefin resin at a volatile antibacterial material 1 at a point where a cool air passes inside a refrigerator. Then, an antibacterial constituent particle 11 is impregnated with a gel-shaped substance 2. Also, the amount of sustained release of the antibacterial constituent is increased against the temperature increase in a container due to the opening/closing of the door by the sustained release film made of a shape memory resin due to temperature, thus dispersing the antibacterial constituent into the refrigerator and constantly maintaining the antibacterial constituent concentration in the container, killing germs floating in air and germs being adhered to the surface of food, and hence achieving a high antibacterial effect.
