There is a problem of rising manufacturing costs. Further, when the door having a weak strength becomes large, there is a problem that the composition is difficult due to the warpage and twist of the member. Moreover, even after the door is assembled, there is a problem that the reinforcing member must be added because the strength of the door is weak. Further, since the conventional refrigerator door is made of a door outer panel made of a curved steel plate, in order to form the shape of the handle portion, there is a problem that the pressing process of the door outer panel is increased, and the problem of the large door must be manipulated. Further, since the shape of the steel plate is changed by the spring back, there is a problem that the assembly work between the upper and lower door covers is difficult. Further, since the door outer panel made of a steel plate is used to constitute the entire door, there is a problem that the pattern becomes monotonous with a lack of change. Moreover, since the door cover is also embossed by the shape of the f f of the door outer panel, the grip portion is not clear, and when the upper end portion or the lower end portion of the handle portion is gripped to open and close the door, between the upper or lower side door The gap has a problem of the safety of pinching the finger. Further, in the door cover, the steel plate, and the handle portion of the conventional door, since the shrinkage ratio of each material is different, in the heat cycle test, the skew occurs, and a crack occurs in the door cover. Further, the door inner panel of the conventional refrigerator door is attached to the rear side of the door outer panel and the rear side of the handle, and the door inner panel exceeds the problem of the door outer panel and the handle rear surface due to the warping and twisting of the respective members. SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, and to provide a highly reliable refrigerator which can easily prevent dew of a grip portion, and has a small number of members, and has a strong strength of 2148-7289-PF η 1287611, and A refrigerator manufacturing method that is easy to assemble even if the door becomes large. A refrigerator according to the present invention includes: a refrigerator door covering a chamber opening, and accommodating the storage body in the chamber by opening and closing; the door outer panel is disposed on an outer surface of the refrigerator door, and has an inner door panel combined with the inner side a steel plate of the heat insulating material is formed; the handle is fixed at one side end of the outer door plate, and has a concave portion formed by inserting the hand from the outside and a holding portion for holding the convex portion when the refrigerator door is opened and closed; the door cover The refrigerator door is integrally formed by being fitted to the upper and lower edges of the handle and the outer panel of the door; wherein the handle is formed by extracting a molded article of metal such as aluminum. The refrigerator according to the present invention is capable of preventing the formation of dew even if the heat insulating thickness of the handle portion is thin because the temperature of the outside air is transmitted from the outer panel by the metal heat conduction of the grip portion. Further, since the metal is formed by extraction of a metal such as aluminum, the handle is formed, and even if the strength is increased, the warpage and the twist can be prevented when the door is grown. Further, since the handle is formed by drawing, the handle of the stable shape can be formed by a simple model. Further, since the outer door portion and the handle portion can be made to have different colors, a refrigerator having good design can be obtained. [Embodiment] [First Embodiment] Fig. 1 is a perspective view of a refrigerator to which the present invention is applied. This refrigerator is constituted by a heat insulating box 2 in which a heat insulating material is provided between an outer casing 1 made of a steel plate opened at the front and a resin inner casing (not shown), and the chamber of the heat insulating box is A plurality of chambers are distinguished by a partition structure not shown. The front opening of each of the divided chambers is closed by the swingable doors 3, 4, 5, 6, and 7 in a freely openable manner. In the present embodiment, 3, 4 are refrigerator compartment doors, 5 is an ice compartment door, 6 is a freezer compartment door, and 7 is a vegetable compartment door. 8 is an evaporation basin cover for collecting 2148-7289-PF 8 1287611 • water that occurs in the chamber during defrosting. The door of either chamber is provided with a handle of the same-section shape for opening and closing in the center, indicating a door structure that is opened on both sides. Therefore, the entire number of doors arranged in the upper and lower directions of the refrigerator main body, that is, in the upper and lower directions, has a structure in which the handles arranged in a straight line are emphasized and designed. Except that the widths of the left and right doors that are opened and closed on both sides are the same, and the door heights of the doors 3, 4, and 7 are approximately matched, the lower sections 5 and 6 on the left side are regarded as small heights from the front. • Door. φ Fig. 2 is a perspective view of the door 4 of the present invention. A door outer panel 11 made of a steel plate constituting a front surface, a handle 13 fitted to one side of the door outer panel, a resin inner door panel (not shown) constituting the inner surface of the door, and a door fitted to the upper and lower ends of the door The upper cover 14 and the lower door cover 15 are configured to be filled, injected, or inserted into the heat insulating material. Further, a magnet spacer (not shown) for preventing cold airflow in the refrigerator is fitted around the inner panel side of the door 4. Fig. 3 is a Z-Z cross section of Fig. 2, and Fig. 4 is an enlarged explanatory view of the handle structure. The outer door panel is a rear side 21 which is formed by the front side of the front side of the door, a side surface 21 which is bent rearward from the hinge side end portion of the door, and a rear surface 22 which is formed by bending the rear end surface of the side surface 21 more inwardly. Composition. Further, the corners of the front surface 20 and the side surface 21 may be formed by an arbitrary curvature R, and may be formed by a C-plane having a chamfer as shown in the figure. The handle 13 has the same cross-sectional shape from the upper end to the lower end of the door, and is formed of thin meat by extraction of the metal. This cross section is composed of a rear face 30 which constitutes a position behind the door and which determines the front-rear direction of the inner panel, a side surface 31 which constitutes the side of the door, a concave surface 32 which constitutes the handle, and a convex surface 33 which constitutes the grip portion and the front surface of the door. By integrally forming the concave surface 32 and the convex surface 33, it is seamless and easy to clear 2148-7289-PF 9.1287611 = handle. Here, the 'convex surface 33 is offset from the side, whereby: "増" is the outside of the refrigerator) is inserted into the hand, and the convex surface is held by the hand. From the side of the front side near the front side of the refrigerator and the handle 2 The horizontal gap between the two can be seen in the center of the concave yoke 32. Since the design of the hue and the sensation is the same as that of the convex surface 33, it can be felt that the handle portion has an aeeent as a body. The handle (4) grip portion is inserted into the door from both sides by the center, and the amount of protrusion from the outer surface of the handle convex surface 33 can be suppressed to the grip portion.
又，在作為把持部的凸部33,設置在前端變粗的圓形 狀的中空部34,藉由此中空部，將外型尺寸變寬，不僅方 便握持’同時確保握持部的強度。自冰箱門的外側表面，與 凸W約略才目虽的尺寸冑出。換言之，可得到確保在凸部的内 部没置的中空部程度突出在外方向程度的平面性的冰箱 門。又，在把手側面31，也設有中空部，藉由鋁等的薄肉 的金屬成形品構成的把手的強度，強化在凹面32的兩側以 及作為把手的前端部的凸面和側面的強度，作為薄肉成形部 的變形對策。 又’因為藉由鋁等金屬的抽出構成把手，在自門外板傳 熱時’在凹面32不發生露水沾附，而可使隔熱厚度變薄， 使握持部的凹部變大，相對地，將門變薄，而使食品收納部 擴大等成為可能。在鋁的情形中，施加氧化鋁膜（Alumite) 處理和钱刻處理，而提高設計性。作為金屬，除了鋁以外， 例如’不銹鋼、鎂等被使用。又，雖然此把手的構造係藉由 兩開門說明，但並不限於此，即使設置在冰箱本體的端部， 可得到同樣的構造和效果。 2148-7289-PF 10 .1287611 又’在把手作為強度對策而被設置的肋36係由隔熱材 以及和此隔熱材並用的接著_著門全體而成為—體，且為 用以強固在門内部充殖式、、拿人μ 丨兄填或/主入的隔熱材和把手的接著的錨 (anchor)形狀。在此情形中，錨形狀作為l字型、ζ字型、 或C字型也可。即使在門内部插人隔熱材的情形，也可使用 此錯在隔熱材的固定。 作為隔熱對策而以樹脂被製造的門内板12係設有位在 門外板11的後面22以及把手的後面3〇的凸緣。又，在此 内側，安裝用以保持冰箱本體和門的氣密性的磁鐵墊片的溝 形狀被設置。 把手後面3G的用以防止熱進人腔室内而設置在和腔室 的分隔接觸的Η的㈣仙在兩側不比***人的内板的塾 片***形狀長是較佳地。又，因為在磁鐵墊片吸附的冰箱本 體的部分’防露管被埋設’所以此部分容易比外界溫度高 /皿因為後® 30、侧面31係位在較此部分的外側，自外部 經由此部分侵入内部的熱被限制。Further, the convex portion 33 as the grip portion is provided with a circular hollow portion 34 which is thick at the tip end, whereby the outer portion is widened by the hollow portion, so that the grip portion can be gripped while ensuring the strength of the grip portion. From the outer surface of the refrigerator door, it is similar to the size of the convex W. In other words, it is possible to obtain a flat refrigerator door which is ensured that the hollow portion which is not placed inside the convex portion protrudes to the outside direction. Further, the handle side surface 31 is also provided with a hollow portion, and the strength of the handle formed of a metal molded product of thin meat such as aluminum enhances the strength of the convex surface and the side surface of the front end portion of the concave surface 32 and the front end portion of the handle. Measures for deformation of the thin meat forming part. In addition, since the handle is formed by the extraction of metal such as aluminum, when the heat is transmitted from the outer panel, the surface of the concave surface 32 is not dewed, and the thickness of the heat insulating layer is reduced, and the concave portion of the grip portion is enlarged. It is possible to thin the door and expand the food storage unit. In the case of aluminum, an Alumite treatment and an engraving treatment are applied to improve design. As the metal, in addition to aluminum, for example, 'stainless steel, magnesium, or the like is used. Further, although the structure of the handle is explained by the two opening doors, it is not limited thereto, and even if it is provided at the end of the refrigerator body, the same structure and effect can be obtained. 2148-7289-PF 10 .1287611 Further, the rib 36 which is provided as a countermeasure against the strength of the handle is made of a heat insulating material and a heat insulating material, and is used as a whole body, and is used to be strong. The interior of the door is filled, and the shape of the next anchor of the heat-insulating material and the handle of the person is taken. In this case, the anchor shape may be an l-shape, a U-shape, or a C-shape. Even in the case where the heat insulating material is inserted inside the door, the fixing of the heat insulating material can be used. The door inner panel 12 made of resin as a countermeasure against heat insulation is provided with a flange located at the rear surface 22 of the door outer panel 11 and the rear surface of the handle. Further, on the inner side, a groove shape in which a magnet spacer for maintaining the airtightness of the refrigerator body and the door is attached is provided. It is preferable that the rear face of the handle 3G for preventing heat from entering the chamber and being spaced apart from the chamber is not longer than the insert shape of the inner panel of the inserted person. Moreover, since the portion of the refrigerator body that is adsorbed by the magnet gasket is buried, the portion is likely to be higher than the outside temperature/the dish is because the rear side 30 and the side surface 31 are located outside the portion, and the outside is passed through the outside. Partial intrusion into the interior is limited by heat.

As shown in Figs. 3 and 4, the end portion of the door outer panel is attached so as to overlap the convex surface 33 of the handle 13, by being a wedge of an elastic body provided inside the heat insulating material or the like. ) 16 is pressed into the handle. The wedge system is formed by injection molding and extraction molding of a resin, and is fitted in a space between the rib 37 provided with the handle and the outer panel, and is fixed in combination with the claw shape I of the rib. Further, the handle side portion of the front iron plate of the door outer panel U is held by the handle 13 and the elastic structure 4 of the wedge 16 fixed to the handle, and is held integrally with the handle 13. This wedge 6 is configured to be plurally spanned across the door height 2148-7289-PF 11 1287611, or may be set to be a full length of the door in the up-and-down direction or slightly shorter. Although the wedge 16 is shown in a configuration in which the wedge is fitted and fixed to the handle, elasticity such as integral with the handle may be applied to the outer panel. Fig. 5 is a perspective view of the lower cover 15. The lower cover 5 is formed by injection molding synthetic resin into a shape of a lower edge shape that fits the outer door panel u and the handle 13, and has a flange 40 covering the outer edge of the door outer panel and the handle at the periphery. The groove between the ribs 42 provided on the inner side is provided, and the outer door panel 11 is fitted. Further, ribs 43, 44 fitted to the hollow portions 34, 35 of the handle are provided. As shown in Fig. 5, for the inner door panel 12, the cover is clearly configured to be positioned at the flange or rib. Further, regarding the upper portion 14, as a shape symmetrical with the lower f 15 of Fig. 5, a flange having a shape covering the upper edge of the handle, the outer door panel, and the inner door panel, and a rib provided on the inner side are provided on the periphery. In the hollow portion 34 of the handle, the rib is fitted. Further, the fitting portion between the upper cover 14 and the handle grip portion of the lower cover 15 is provided as a holding space by providing the blocking surface 45, and the division is made clear. Further: • By thus blocking the surface 45, by easily gripping the handle grip portion of the end portion, the finger is prevented from being caught between the door and the other door when the door is closed. In the door which is formed by the door cover of the synthetic resin and the door outer panel made of a steel plate, the skewing system which is different in the extension of the thermal heat ring test may be used in the weakest door cover.

Further, by making the upper cover or the lower cover two members, the flange 41 of the small cover 51 can be made higher or lower than the flange 4 of the large cover 5, so that the metal as the appearance can be obtained. The exposed area of the handle portion of the extraction member is reduced or enlarged, and there is a rich change in appearance. Further, as shown in Fig. 4, by providing the inclined surface guiding portion 39 for guiding when the inner surface of the handle 30 is inserted into the inner panel, the inner panel flange of the door is covered when covering the inner panel of the foamed heat insulating material. The system will not flow over the back of the handle and slip, so that the foaming of the door will disappear. Next, 'the assembly sequence is explained. The door outer panel 11 is assembled at a predetermined position of the handle 13 so that the wedge 16 is engaged with the rib 36 of the handle 13, and the outer panel is clamped to the handle 13 by the wedge 16. Thereafter, the door under cover 15 is attached from below the fitted handle 13 and the door outer panel 11. At this time, an outer door panel is inserted between the flange 4A of the lower cover 15 and the rib 42, and the flange 4 is attached to the outside of the door outer panel and the handle i3. Further, the ribs 43, 44 provided in the lower cover 15 are inserted into the hollow portions 34, 35 of the handle. Further, the large cover 50 and the small cover 51 are integrally assembled by being fitted to each other in advance. Next, the upper cover 14 is attached from above the fitted handle 13 and the door outer panel 11. At this time, the end surface of the door outer panel is inserted between the outer peripheral flange of the upper cover and the rib, and the outer peripheral flange overlaps the outer surface of the door outer panel 11 and the handle 13. Further, the ribs provided in the upper cover 14 are inserted into the hollow portions 34, 35 of the handle, and then the door inner panel 12 is temporarily fixed across the rear surface 22 of the outer door panel 11 and the rear surface 30 of the handle 13, and moved to foaming. The heat insulating material injection device, after the south door inner panel 12 is injected to inject the foam heat insulating material, surrounds the door outer panel by covering the inner door panel 12'; [1, the handle 13, the upper and lower covers 14, 15 and the inner door panel 12 2148- The space inside the 7289-PF 13 and 1287611 is filled with foam insulation material to make it adhere and solidify to make the door/integrated. Further, even in the structure in which the heat insulating material is inserted, the structure is carried out in the same order. Further, although the structure of the door body is described by the door 4, the other doors 3, 5, 6, and 7 have the same structure. Further, in the example of the present embodiment, the widths of the compartment left door 3, the refrigerating compartment right door 4, the ice compartment door 5, the cold bundle chamber door β^η, and the vegetable compartment door 7 are the same. The handles and outer panels of each door are the same-section shape. Further, when a vacuum heat insulating material is used without using a foamed heat insulating material, the structure of the vacuum heat insulating material such as an outer panel can be used as an integral door structure. But even if the frame size at this time is changed by each door, of course. Since the handle is constituted by the metal extraction member such as aluminum, the strong force of the door can abolish the reinforcing member added for the purpose of reinforcement. Moreover, since the warpage and the twist of the member are small, the assembly work of the door is also easy. By using a lightweight alloy as a metal, the increase in weight is suppressed, and the entire refrigerator is increased in strength, and deformation and skew occurring during movement during transportation and transportation are suppressed, and it is filled in the refrigerator. The possibility of leakage of cold coal such as hydrocarbons and CFCs in the refrigerating cycle is reduced, and an ice tank having high reliability can be obtained. Since the cross-sectional shape of the handle and the outer panel of the door is spanned up and down, the doors are arranged the same. Therefore, the height of the refrigerator door can be changed without adding a special model, and the shape of the upper cover and the lower cover also becomes a symmetrical shape, and the design is easy. Further, as shown in Fig. 1, by arranging the door shape of the entire refrigerator, in addition to the fact that the handle portion # of the upper and lower full lengths of the center portion of the front portion of the refrigerator is coordinated, the uniformity of the components and the number of components are reduced. The manufacture is simple. Since the rib can be provided as an anchor in the handle, the foamed heat insulating material can be filled, fixed, and the like, and used for fixing the heat insulating material, it is not necessary to perform the screw lock 2148-7289-PF 14 • 1287611, etc. Since the post-processing is adopted by a structure assembled by fitting, it can be manufactured at a low price. Since the handle is made of a metal such as aluminum, it is possible to obtain a handle having a good design unlike the color and texture of the outer panel without secondary processing such as painting. Since the end portion of the grip portion of the handle is made hollow, a handle that is easy to grip and has high strength can be obtained. Because the side of the cover is disposed on the side of the handle and the outer panel of the door, even if the longitudinal dimension of the outer door and the handle is in error, a design door having no gap can be obtained, and the foamed heat insulating material can be prevented. leakage. Since the rib is inserted into the hollow portion of the handle in the cover, the position at which the cover is fitted to the * handle is determined easily. Since the elasticity of the wedge is used as the structure for pressing the outer panel to the handle, the gap between the outer panel and the handle is prevented, and a door having no gap and good design can be obtained, and leakage of the foamed heat insulating material can be prevented. Further, since the pressing operation of the outer panel having a large size and a large weight is not required, the mounting is a work of only fitting and separating the hot material, and the assembly is easy and the manufacturing is simplified. Further, since the handle portion has a concave shape of the grip portion, the heat insulating thickness of the door is reduced, and in the case of high humidity use, although the dew is adhered to the grip portion, the heat conduction in the chamber is not received. The magnet spacer is formed on the outside of the chamber, and the metal such as aluminum having good conductivity can prevent the dew of the handle portion from being adhered by the heat of the outer panel. Since the widths of the left and right doors of the refrigerator are the same, the members of the door and the handle, for example, the upper and lower covers have the same shape in the upper left and the lower right, and the members of the door outer panel, the inner panel, and the like are reversed up and down, and the members are common. Promoted, ie 2148-7289-PF 15 * 1287611 • Allows the number of necessary models to be reduced in a refrigerator with multiple doors. In addition, when the discarded refrigerator is recycled, there is no screw or the like, and it is not only easy to disassemble, but also the member and the structure are common, and the decomposition work is also easily performed. The refrigerator of the present invention includes a refrigerator door covering a surface of a chamber for accommodating food or the like, and accommodating the storage object in the chamber by opening and closing; the outer panel of the door is formed on the outer panel of the door; the heat insulating material is disposed outside the door The plate is opposite to and combined with the inner panel of the door for heat insulation; the handle is fixed at one side of the outer panel of the door, and has a recess for inserting the hand from the outside and for holding the refrigerator when the refrigerator door is opened and closed a grip portion formed by the convex portion; the door cover is fitted to the upper edge and the lower edge of the handle and the outer panel of the door, and the refrigerator door is integrally formed; since the handle is formed by extracting a metal such as aluminum, The number of components and the common component structure' can be obtained in a refrigerator which is simple to manufacture and highly reliable. In the refrigerator of the present invention, the recess of the door cover that is fitted to the upper and lower edges of the handle is not blocked, and when the door is opened and closed, the holding space is made clear, that is, the distinction is made in the area where the hand enters the person. A safe and easy to use refrigerator is available. In the door system of the refrigerator of the present invention, the door cover that is fitted to the upper and lower edges of the handle is repaired as two members, and in the combined portion of the metal member such as a steel plate or aluminum or the cover, cracks in the heat cycle test can be prevented. A refrigerator with high reliability and good performance is obtained. In the refrigerator of the present invention, the door cover that is fitted to the upper and lower edges of the handle is formed into two members, and the exposed area of the handle portion can be enlarged or reduced in appearance, and a design with a wide variety of changes can be obtained. When the refrigerator of the present invention carries the inner panel behind the handle, since the guiding shape of the inner panel is provided, the possibility of manufacturing failure is reduced. Since the present invention is constructed by a metal handle and can be simply formed as an integrally formed door structure by the upper cover 2148-7289-PF / - 1287611 cover, the water adhesion of the grip portion can be easily prevented. Moreover, the food storage portion can be enlarged, and even if the strength is strong and the door is changed to be large, the assembly can be easily performed, and the refrigerator door without the reinforcing member is not required. Further, the present invention can be stably assembled by a simple model structure, a reduction in processing such as pressing, and a refrigerator door having good design can be obtained. A refrigerator door system according to the present invention includes: a door outer panel; a handle at which one side end of the door outer panel is embedded, having a grip portion; the door inner panel being combined with the outer panel; the door cover being at the upper and lower edges In the refrigerator door in which the foamed heat-insulating material is filled, the handle is formed by extracting a metal such as aluminum, and a refrigerator having a simple structure and high reliability can be obtained. The door opening on both sides of the refrigerator according to the present invention can ensure the size of the grip portion and the heat insulating thickness of the concave shape of the grip portion by making the opening portion of the handle in the holding direction. Further, since the outside temperature of the outer panel is guided by the heat conduction of the metal, even if the heat insulating thickness of the handle portion is reduced, the dew condensation can be prevented. In addition, since the handle is formed by extracting a metal such as aluminum, warpage and twisting can be prevented even when the door is lengthened as strong. Further, since the handle is pulled by the drawing, the handle of the stable shape can be formed by a simple model. Further, since the door outer panel portion and the handle portion can be made to have different colors, a refrigerator door excellent in design can be obtained. A method of manufacturing a refrigerator door according to the present invention includes: a side end of an outer door panel assembled to form an outer surface of a refrigerator door, and a concave portion for inserting a hand from the outside when the refrigerator door is opened and closed, and a convex portion for holding When the handle of the grip portion is formed, the outer panel assembly step is performed by sandwiching the outer panel of the handle with the outer panel of the handle; the handle assembled at the outer panel assembly step and the upper and lower edges of the outer panel of the door engage the door cover The door forming step in which the refrigerator door is integrally formed; since the door 2148-7289-PF 17 1287611 is fitted from the outer side and the inner side of the upper and lower edges of the door outer panel, it is possible to easily manufacture a highly reliable refrigerator.
