Abstract: PURPOSE:To prevent the dewing on the surface of the decorative panel by a simple construction and facilitate the assembly process by disposing screw holes for attaching the decorative panel and a height difference for a reinforcement plate around the rim of the door main body, covering the screw heads with a gasket, and fitting a reinforcement plate to the lower part of the door main body. CONSTITUTION:A through-hole 17 is disposed in the main body 14, and the main body 14 and a decorative panel 15 are fixedly joined together with screws 18. The screws 18 are installed from the inside of the cabinet, and the screw heads are covered with a gasket 16. A reinforcement plate 20 for attaching the decorative panel 15 is fitted to the lower part of the main body 14. When a refrigerator having the present heat insulated door is set as a part of a system kitchen, a coordinated visual impression is obtained since the same surface material and color tone are used for the door decorative panel 15, while the reinforcement plate 20 is hidden from the frontal view because of the height difference 15a. The heat insulation performance is ensured by the insulation material 7 filled in the door main body 14. In regard to the attachment of the decorative panel 15 to the door main body 14, there is no need for a complex construction as was seen in the prior art because the reinforcement plate 20 is fitted to the lower part of the main body 14 and the attachment screws 18 are covered under the gasket 16, facilitating the assembly process. Therefore, the heat insulated doors can be manufactured at less cost.

Abstract: PURPOSE:To prevent content to be placed from being iced on the side faces of an inner box and to easily remove the content out of a refrigerator by providing a drainboard made of synthetic resin having at least a bottom and opposing side faces. CONSTITUTION:A drainboard 9 having at least a bottom and opposing two side faces, 20mm of an interval and four or less of corners is made of synthetic resin. It is so formed as an inner box as to place a content to be placed on the bottom, and it is not apprehended to ice even if it is brought into contact with the side faces of the inner box due to the inclination of the content to be placed. For example, even if the other side on which no drainboard 9 is disposed is iced, the content can be easily removed by holding the side of the drainboard 9. Thus, since it not only prevents the content from adhering to the side face of the inner box due to icing but it is brought into point or linear contact therewith in a small contacting area even if the content adheres thereto, the content can be easily removed.

Abstract: PURPOSE:To prevent condensed water and water from a defroster from dripping onto the floor by providing a dew receiving tray coupled with a condenser on a reinforcement plate for a rail device external to a kitchen waste cabinet with a refrigerator and located below a container installed behind a sliding door in such a manner that the dew receiving tray is always kept opposed to a drain hole internal to the cabinet as it is put into or drawn out from the cabinet. CONSTITUTION:A dew receiving tray 18 is provided on a reinforcement plate 16 connecting a right-hand and left-hand rails of a rail device 17 for sliding a door 11 back and forth in such a manner that it is always kept opposed to a drain hole 19 made in a body 9 not only when the dew receiving tray 18 is placed in the body 9 but also when the dew receiving tray 18 is drawn out together with the door 11 and a container 13. Water that has been collected is evaporated by heat from a condenser 21, thereby preventing condensed water and water from a defroster from dripping onto the floor.

Abstract: PURPOSE:To improve the operation ability of the subject garbage storage in a sanitary condition without discomfort by detachably mounting a kitchen garbage container whose upper surface is opened on the storage inside of a drawer-type door, and setting a lid which is in close contact with the opening on the upper surface when the door is closed. CONSTITUTION:Kitchen garbage 7 is stored in a garbage storing container 13 with an opening on its upper surface, which is fixed to the storage inside of the door 11 of a garbage storage whose inside area is cooled down below 0 deg.C. A lid 14 for sealing the opening area when the door is closed, and for opening the opening area by means of a weight 14b when the door is opened, is provided for the storing container. Consequently, a bad smell is not directly sent out from the storage inside and front which has been produced from water vapor including the bad smell is not generated on an inside box in the storage. And when the storage is defrosted, water generated by defrosting is stored in an evaporating dish 16 through a drain hole 15. When the water is automatically evaporated due to heat from a condenser 18, neither a bad smell nor a nasty smell is sent out in a sanitary condition without discomfort. And also, when the door is opened so that the kitchen garbage 7 is stored in the garbage storing container 13, the kitchen garbage can be stored therein without removing the lid 14 every time.

Abstract: PROBLEM TO BE SOLVED: To prevent electric equipment from becoming an ignition source, even if combustible refrigerant is leaked, in an electric equipment cover for a compressor using the combustible refrigerant. SOLUTION: In this electric equipment cover 1, a rib 1a is constituted in such a state as surrounding an overload protection device 3 and a slit part 1b is provided therein. The slit part 1b is provided with a cord 3a having a length sufficient in being drawn out to the outside of the rib 1a, when the overload protection device 3 is fitted thereto. The inside of the rib 1a is hermetically sealed by a sidewall 3b of the overload protection device 3, a sealed bottom face 3c, and the cord 3a so that a terminal part 3d of the overload protection device 3, in which the combustible refrigerant is liable to enter, is protected from being exposed to the combustible refrigerant and the combustible refrigerant is prevented from entering into the inside contact part 3e. This constitution can eliminate the combustible refrigerant from entering into the inside of the overload protection device 3, even if the combustible refrigerant is leaked, thereby eliminating it from becoming the ignition source.

Abstract: PROBLEM TO BE SOLVED: To suppress the quantity of chill of a vegetable room at overload time of a storeroom so as to prevent the partial freezing and dew condensation of a vegetable room, by providing a partition plate with many pieces of communication ports, and providing this refrigerator with a chill passage between the partition plate and the cover of the vegetable room. SOLUTION: A fan device 9 is activated, and for the chill cooled with a cooler 8, its one part reaches a duct 30 for vegetable room through a duct 20, being branched with a duct 19 through a duct 11 and a damper room 16 from a blast port 12. In this duct 30, it is mixed with the chill being led through a communication port 29 from a storeroom 5, and it cools a vegetable room 5 from many pieces of mixed chill discharge ports 31 provided at the bottom of the duct 30. Then, this chill cools the flank after cooling the ceiling of the vegetable room 33 equipped with a cover 32 first, and then, cools the bottom. After cooling the vegetable room 6, it returns from a backward path 22 for vegetable room positioned in front of a partition wall 28. Accordingly, the chill being cooled never directly hits on the vegetable and exerts a bad influence upon the freshness preservation.
