[Prior Art] In recent years, in order to reduce the power consumption of the refrigerator, not only cooling control but also various technical measures have been studied for the heat insulating structure of the refrigerator main body. Among them, a large proportion of the heat leakage from the storage chamber is a leak from the gap seal portion around the door around the opening portion of the refrigerator, and therefore an improvement in the configuration for further reducing the amount of heat leakage is required. Therefore, for example, there is a configuration in which a guide body for rectifying and lowering the cold air supplied into the freezer compartment and falling in the gap between the freezer compartment container and the door is provided on the door side of the freezer compartment. In this way, the cold air current flowing in the gap is prevented from reaching the gap seal side around the door, and the energy loss due to heat leakage or the condensation at the gap seal portion around the door or the like is prevented (Patent Document 1 ). [PRIOR ART DOCUMENT] [Patent Document] Patent Document 1. Japanese Patent Laid-Open No. 2006-78025. However, in the constitutional towel of the above-mentioned patent document, although the cold air is rectified to the lower side of the door, it is still impossible to prevent cold air. The flow to the gap seal around the door. Therefore, in order to reduce the heat from the gap seal portion around the door to reduce the power consumption of the refrigerator, it is required to further improve the improvement of the air-tight flow to the gap seal portion around the door.

The door 12 is configured such that an outer panel 30 is disposed on the rigid side of the window frame ((10)) 29 forming the outer frame, and an inner panel 3! facing the freezer compartment 6 is disposed on the rear side, and the outer panel 3G is The foamed heat insulating material 32 is filled between the plates 31. The cold shirt ϋ 24 and the cold blouse (4) surface and the space 2 are formed with a gap 'but as shown in Fig. 4, the upper end protruding edge 24a of the cold bundle chamber container 24 is made. In contact with the inner panel 31 of the crucible 12, the cold air ejected from the cold air ejection port 2 does not directly flow from the upper side into the gap G between the inner panel 31 and the cold chamber; A mounting groove % is provided in the peripheral portion of the inner panel 31 of the cold/east chamber door 12, and a magnetic seal gasket 34 which is a void member is attached to the t-mounting groove 33. When the door 12 is closed, the magnetic portion 35 of the magnetic gasket 34 is attracted to the front surface of the opening of the steel outer casing 2a around the opening of the front surface of the east chamber 6, whereby the door 12 is The outer box 仏 empty 201113488 gap seal. In the inside of the foamed heat insulating material 2c, a refrigerant pipe 36 is provided at a position outside the magnetic seal dam 34, and a high-temperature refrigerant discharged from the compressor 27 of the refrigeration cycle flows through the refrigerant pipe 36. The side refrigerant %* 36 heats the _ steel plate and the air box to prevent the periphery of the opening of the outer surface 2a from becoming low temperature, and the water droplets adhere to the surface. The surface of the freezing compartment door 12 facing the freezing compartment 6, that is, the inner panel 31, is integrally formed at substantially the entire lower side and the substantially lower half of the left and right sides of the periphery of the portion surrounded by the magnetic sealing jaws 34. Projecting portions 37, 38 are protruded from the ground. Sealing fins (fins) 39 are attached to the lower portion of the lower protruding portion 37 and the outer portion of the protruding portion 38 along the left and right sides. The seal fin 39 includes two soft fins 39b, 39c projecting from the front and rear sides of the mounting portion 39a of the projections 37, 38. The front end portions of the front and rear soft fins 39b and 39c are gently brought into contact with the front surface of the inner bottom surface of the cold beam chamber 6 and the front portions of the left and right inner sides, and the gap between the inside of the freezing chamber 6 and the magnetic gasket 34 is two. Separate space. The lower cold airtight sealing plate 40 and the side cold air sealing plate 41 are attached to the front end portions of the Song throwing portions 37 and 38 (see Figs. 3(a) and 3(b)). The lower cold air sealing plate 40 and the side cold air sealing plate 41 are fitted to the mounting grooves 42 formed at the front end portions of the protruding portions 37 and 38 by fitting the base portions of the lower cold air sealing plate 40 and the side cold air sealing plate 41, respectively. 43 is attached, and the projections 42a and 43a (refer to FIG. 1, 201113488 Η) card & formed on the inner surfaces of the mounting grooves 42, 43 are formed into the engaging holes of the bottom portion of the lower air-sealing sealing plate 4 and the side 41. 4Ga and 41a prevent the detachment of the side cold air sealing plate 41 by 40. .卩7 礼岔封板 The lower cold air sealing plate 4〇 and the side portion 41 installed in this manner can be forcibly removed. In the state of the lower cold air sealing plate "= plate 4: corpse ampere? freezer compartment door 12, extending from the cold: chamber door along the inner surface of the freezing compartment 6, that is, the inner bottom surface, / toward the inner side of the cold venting chamber 6 The two inner side surfaces on the left and right sides of the bottom surface and the side cold air sealing plate 4! have a rectangular plate shape, but the fairy is formed into a curved shape, and the lower cold airtight member is the mounting plate portion 4 of the base of the engaging hole. %, f part 4〇C, and the mounting plate portion 4〇b and the horizontal plate portion 4 the skew plate portion 40d. The mi is only inclined along the upper surface of the protruding portion 37 of the lower side of the inner plate 31. The degree of inclination of the plate portion 40d becomes substantially the same as the inclined upper surface 37a of the protruding portion 37 such that the inclined 丄 surface μ of the protruding portion 37 is substantially the same as the inclined plate portion 4〇d axis of the lower cold air sealing plate 4A. Moreover, due to the presence of the sloping plate portion, the horizontal plate portion 4〇c approaches the inner bottom surface, thereby narrowing down with the cold; the inner bottom surface of the east chamber 6 is second in sequence, and then the pair has the heat The description of the operation of the refrigerator is blocked. As described above, the cold air discharged from the cold air outlet 21 is not straight. From the top, it flows into the inner panel 11 201113488 of the cold-collar chamber door 12, but there is cold air in the gap G. The void naturally falls in the gap G. The inner cold air passes through the outer periphery of the inner panel 31. The sealing plate 4 on both the left and right sides suppresses the diffusion of the cold air which is lowered in the gap G = the peripheral portion of the right side of the cold air, and descends toward the bottom side of the freezing compartment 6. The left "falls from the upper side of the cold beam chamber 6 to the lower cold air seal" The cold air lining of the plate 40 is connected to the inclined side plate portion 40d of the substantially side-protruding portion 37_the upper surface (10) and the lower cold air sealing plate 40, and flows on the upper side of the lower cold air sealing plate 40, thereby becoming the cold room. The flow on the inside of 6. By the flow, it is prevented from flowing to the magnetic gasket 34 side when the cold air falls to the inner bottom surface of the freezing compartment 6, and the gap H between the horizontal plate portion 40c of the lower cold air sealing plate 40 and the bottom surface of the inner casing 2b is narrowed, so that The amount of cold air flowing from the gap to the side of the magnetic gasket 34 is reduced. When the cold air flows from the gap to the side of the magnetic sealing jaw 34, the cold airflow is prevented from being directed to the side of the magnetic gasket 34 by the fins 39b, 39c of the sealing fin 39. Moreover, heat blockage can be effectively performed due to the existence of two independent sealed spaces formed by the fins 39b and 39c. As a result, heat leakage around the cold room door 12 can be reduced, thereby reducing power consumption. In addition, since the steel outer casing 2a or the magnetic gasket 34 that faces the opening between the freezing compartment door 12 and the branch foot 28 is cooled by the cold air from the cold room 6, it is prevented from being around the door 12. The effect of condensation on the surface of the magnetic gasket 34 or the outer casing 2a. Since the lower cold air sealing plate 40 and the side cold air sealing plate μ are separately provided from the cold 12 201113488 freezing chamber door 12, the inner sealing plate 41 of the door 12 is integrally formed to correspond to the lower cold air sealing plate 40 and the side cold air sealing plate 41. In comparison with the case of the portion, the thickness of the cold air sealing plate 40 can be made thinner, whereby the inner plate 31 which is cooled to the door 12 is formed of a thin plastic plate, so that it is inside When the lower cold airtight sealing plate 4 and the side cold air sealing plate 41 are integrally formed on the plate 31, it is necessary to fill the foamed heat insulating material 32 in the same manner as the protruding portions 37 and 38 to form a thicker portion to increase the strength. If the lower cold air sealing plate 4 〇 and the side cold 1 sealing 加厚 are thickened in this way, the inner volume of the cold/east to 6 is reduced or the cold sump chamber 24 is slightly miniaturized so that the lower cold air seal is sealed. The crucible and the side cold air sealing plate 41 do not come into contact with the freezing compartment container 24 or the like, and the amount of cold food storage is reduced. 7/to 'the present job towel' consists of a thick (four) (four) plate to form a lower cold milk-sealed plate 40 and a side cold air-sealing plate 4, whereby the food storage amount of the above-described cold-compartment room 6 can be reduced. occur.

Different parts are explained. The cold seal of the gap seal around the cold roll 12 of the application form is blocked, that is, as shown in FIG. 5, the lower cold seal plate 4 (mm) is also 'not shown' but is air-cooled at the side. The sealing plate 41 is cold; the east chamber 201113488 is also adhered to the surface of the container 24 side with the heat insulating sealing material 44. Thereby, the lower cold air sealing plate 40 and the side cold air sealing plate can be prevented from being passed, and the cold heat can be transmitted along the thickness direction of the plate to be cooled by the air on the side of the sealing pad 34, so that the cooling can be further reduced (4). [Embodiment 3] FIG. 6 shows a third embodiment of the present invention, and in the third embodiment, the same portions as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. For details, only the different parts will be explained. The heat blocking of the gap seal portion around the freezing chamber door 12 of the second embodiment is configured as follows, that is, as shown in FIG. 6, a soft flexible gasket is attached to the front end portion of the lower cold air sealing plate 4A. (packing) 45, when the cold room door 12 is closed, the liner 45 is close to the inner bottom surface of the freezing compartment 6 (there is a slight gap H). The gasket 45 may also be in contact with the inner (bottom) surface of the freezing compartment 6. Moreover, in the present embodiment, this situation is expressed as close even when there is a slight gap Η. Similarly, although not shown, a pad 45 is attached to the front end portion of the side cold air sealing plate 41. When the freezing chamber door 12 is closed, the pad 45 is adjacent to the side of the inner box 2b of the heat insulating box 2. . As a result, the gap between the lower cold seal plate 40 and the side cold air seal 41 and the inner surface of the freezer compartment 6 is narrowed by the spacer 45, so that the lower peripheral portion and the left and right peripheral portions of the door 12 can be further reduced. The amount of cold air on the side of the magnetic gasket 34. Further, in the embodiment shown in Fig. 201113488, the door peripheral member 44 that can surround the refrigerator compartment 3, the vegetable compartment 4, the ice making compartment 5, and the like is not limited to the lower air-cooling sealing panel 40. The surface of the oxygen sealing plate 41 may be disposed on the back surface or may be placed on both sides. It is also possible to attach both the heat insulating sealing material 44 and the gasket 45 to the lower cold air sealing plate 4'' and the side cold air sealing plate 4.
