Description

Refrigerator

The present invention relates to a refrigerator in which a handle is provided on a drawer-type door.

In conventional refrigerators, there has been a product in which a drawer-type door is provided with a handle (for example, refer to Patent Document 1). In the refrigerator disclosed in Patent Document 1, a handle is provided on the upper side of two drawer-type doors arranged side by side. In this case, when the handle is located higher than the user's own shoulder, it is difficult for the user to pull out the door panel. There is only one handle on the drawer-type door, which may make it difficult for users to open and close the door due to different heights.

With respect to this problem, there is known a refrigerator in which a handle is provided in front of a drawer-type door (for example, Patent Document 2). In the refrigerator disclosed in Patent Document 2, a recess is provided on the front plate of the door panel, and a holding member that spans the recess is provided. With this refrigerator, a taller user can easily pull out the door if the door piece is lower than his shoulder and grasps the holding member with his palm facing down. In addition, a user with a short height can easily pull the door piece out if the door piece is located on the upper side of his shoulder and grasps the holding member with his palm facing up. Although there are such advantages, if the door can be easily grasped with one handle with the palm facing up or down, the shape of the handle becomes complicated and the manufacturing cost becomes high. In the case of the refrigerator disclosed in Patent Document 2, it is necessary to perform sheet metal processing for forming depressions on the front plate of the door piece, and this processing also affects the manufacturing cost. In addition, the design of the front panel is restricted due to the recess provided on the front panel of the door panel.

A refrigerator having two handles on the side of the door is known (for example, refer to Patent Document 3) as a countermeasure to the above-mentioned problem. In the refrigerator disclosed in Patent Document 3, handle portions are provided at the uppermost portions of both sides of the door pieces of the storage room on the lower side of the storage room on the lower side of the storage room on the four floors. In this refrigerator, a vacuum heat insulating material in close contact with the front panel of the door piece is arranged inside the door piece, and handles are provided at the uppermost part on both sides of the vacuum heat insulating material.

Furthermore, there is known a refrigerator, although it is not a drawer-type door piece, but a plurality of handles are provided on the side-opening door piece (for example, refer to Patent Document 4). Patent Document 4 discloses a configuration in which handles are provided on three surfaces of the side surface, top surface, and bottom surface of the split door of the uppermost storage room. Patent Document 4 describes that the effect is that anyone can easily open and close the door panel by appropriately selecting the handle according to the user's preference and height. On the other hand, the double-opening door panel rotates with a hinge provided on the side facing the side where the handle portion is provided as an axis, and its opening and closing action is different from that of a drawer-type door panel that moves back and forth. Using the technology of the two-sided door panel directly on the drawer-type door panel can not achieve the same effect as the two-sided door panel.

In the refrigerator disclosed in Patent Document 3, the uppermost handle portions provided on both sides of the door pieces have the same height from the floor. Therefore, when the drawer-type door is provided on the upper layer, it may be difficult for a user with a short height to open and close the door.

In order to solve the above-mentioned problems, the present invention provides a refrigerator that can easily open and close the drawer door panel without being affected by the height of the user.

The refrigerator of the present invention includes: a box body provided with a heat insulating material between an outer box and an inner box; a drawer compartment provided in the inner box with an opening in the front; by moving in the front and rear directions, the drawer compartment The door piece for opening and closing the opening; the door piece includes: a main handle portion provided on the upper side; a sub-handle portion provided on the lower side; the door piece is composed of an upper plate provided with the main handle portion and the sub-handle portion The two above-mentioned door pieces are arranged to be adjacent to each other up and down; among the two above-mentioned door pieces, the sub-handle portion of the upper door piece and the above-mentioned main part of the lower door piece The handle portions are arranged in positions facing each other; the depth length of the auxiliary handle portion of the upper door piece is shorter than the depth length of the main handle portion of the lower door piece; the auxiliary handle portion of the upper door piece and the lower The distance between the openings between the main handle portions of the side door pieces is greater than the depth length of the auxiliary handle portion.

According to the present invention, both the upper side and the lower side of the drawer-type door panel are provided with handles. Therefore, the user is not affected by height and can easily hook the handle with his fingers, thereby reducing the burden of opening and closing operations.

Fig. 1B is a plan view of the refrigerator shown in Fig. 1A when viewed from above. Fig. 1C is a side view showing a configuration example when the refrigerator shown in Fig. 1A is viewed from the side. Fig. 1C shows the side surface on the right side when looking at the front of the refrigerator 1 (when looking at the refrigerator 1 in the direction of the Y-axis arrow) in the configuration shown in Fig. 1A. In FIG. 1C, the side panel 32 on the right side of the refrigerator 1 is shown, and the side panel 32 is also provided on the left side of the refrigerator 1.

As shown in FIG. 1A, the refrigerator 1 includes a refrigerating compartment 2, a freezing compartment 27, and a vegetable compartment 6 as a storage compartment for refrigerating or freezing storage items such as food. The freezing compartment 27 has an ice making compartment 3, a first freezing compartment 4 and a second freezing compartment 5. The refrigeration temperature is, for example, 10°C or lower. The freezing temperature is, for example, -12°C or lower.

As shown in FIG. 1A, the refrigerating compartment 2 is provided on the uppermost layer of the refrigerator 1, and the ice making compartment 3 and the J-th freezing compartment 4 are arranged side by side under the refrigerating compartment 2. A second freezer compartment 5 is provided under the ice making compartment 3 and the first freezer compartment 4, and the vegetable compartment 6 is provided under the second freezer compartment 5.

In addition, the refrigerator 1 has a plurality of door pieces 7 to 12 that open and close the front of the storage room. Door pieces 7 and 8 are provided in the front of the refrigerator compartment 2. The doors 7 and 8 are side-by-side doors that open and close the refrigerator compartment 2. Door piece 7 is the left door piece, and door piece 8 is the right door piece. The front of the ice making chamber 3 is provided with a door piece 9. A door piece 10 is provided on the front of the first freezing compartment 4. A door piece 11 is provided on the front of the second freezing compartment 5. A door piece 12 is provided in front of the vegetable room 6.

Door pieces 7 to 12 are drawer-type door pieces of each storage compartment of the ice making compartment 3, the first freezing compartment 4, the second freezing compartment 5, and the vegetable compartment 6. Hereinafter, the storage room whose front is opened and closed by the drawer-type door moving in the front-rear direction is called a drawer room. Drawer-type doors move in the front and rear directions to achieve the function of opening and closing the drawer compartment. For example, the door piece 11 is provided in front of the second freezing compartment 5, and by moving in the front-rear direction, the opening of the second freezing compartment 5 is opened and closed.

Fig. 2 is a cross-sectional view of the part A-A shown in Fig. 1B. The refrigerator 1 has a refrigerant circuit connected by refrigerant pipes, such as a blower 16, a cooler 17, a compressor 18, a condenser, a capillary tube, and the like. A heat radiating pipe (not shown) is provided between the side panel 32 which is a part of the outer profile of the refrigerator 1 and the foamed heat insulating material 19 as a condenser. The heat radiating pipe transmits the heat of the circulating refrigerant through the side panel 32 shown in FIG. 1C to radiate heat to the outside. The configuration of the heat radiating pipe will be described in detail below. As the refrigerant system, for example, isobutane whose refrigerant name is R600a is used. Other refrigerants can also be used as the refrigerant, but isobutane does not destroy the ozone layer after being discarded, and has the advantages of low warming coefficient and so on.

In addition, the refrigerator 1 is provided with an air path (not shown) through which cold air flows from the cooler 17 to each storage room. Electric opening/closing air locks (not shown) are provided in each air passage. A control device 14 for controlling the freezing cycle of the refrigerator 1 is provided behind the uppermost part of the refrigerator 1. The control device 14 is covered by the upper cover 13. The control device 14 is, for example, a microcomputer. The control device 14 controls the number of rotations of the compressor 18 and the blower 16 and the opening degree of each opening and closing air lock so that the refrigerating temperature and the freezing temperature in the refrigerator 1 are respectively set temperatures.

Through the refrigeration cycle, the air cooled by the cooler 17 is blown to each storage compartment of the refrigerating compartment 2, the freezing compartment 27, and the vegetable compartment 6 via the blower 16. At this time, the control device 14 controls the opening degree of the opening/closing dampers provided in each air passage to adjust the amount of cold air flowing into each storage compartment.

Next, the box 30 constituting the outer profile of the refrigerator 1 will be described. First, the method of foaming the foamed heat insulating material 19 in the box 30 will be described. Here, the case where the foamed heat insulating material 19 is polyurethane foam will be described.

Fig. 3 is an external perspective view for explaining the foaming procedure of the refrigerator box shown in Fig. 1A using a foamed insulation material. Fig. 4A is a cross-sectional view of the part B-B shown in Fig. 1C. Fig. 4B is an enlarged view of the circle F shown in Fig. 4A. As shown in FIGS. 3 and 4A, the box body 30 has an inner box 31 that partitions each storage compartment, and an outer box 21 including a side panel 32 and a back panel 20. The outer box 21 constitutes the outer profile of the refrigerator 1.

The side panel 32 and the back panel 20 shown in FIG. 3 are comprised by the iron plate whose board thickness is about 0.4-0.5 mm, for example. A pair of members for hooking and fixing the inner box 31 to the outer box 21 are provided on the box body 30. As shown in FIGS. 4A and 4B, on the front side of the outer box 21, an R-curved portion 21a is provided as one of a pair of members. The locked portion 31a is provided on the front side of the inner box 31 as the other of the pair of members. The R-curved portion 21a is elastically deformed to clamp the clamped portion 31a, whereby the outer box 21 and the inner box 31 are engaged and fixed to each other.

When the polyurethane foam stock solution is injected into the space between the outer box 21 and the inner box 31, as shown in FIG. 3, the box 30 is set in a foaming device not shown, and the box of the refrigerator 1 The back panel 20 of 30 faces the upper side. Then, the polyurethane foam stock solution is injected from a plurality of injection ports 33 provided in the back plate 20.

The injected polyurethane foam stock solution flows between the outer box 21 and the inner box 31 along the inner wall to the whole. After that, the polyurethane foam starts to foam toward the back panel 20 and fills up the space between the inner box 31 and the outer box 21.

Furthermore, before the polyurethane foam stock solution is injected, the vacuum heat insulating material 23 shown in FIG. 4A is temporarily fixed to the inner surface side of the outer box 21 with a hot melt adhesive, a sealing material, and the like. The vacuum heat insulating material 23 is provided with a recess 29 in advance, and the heat radiation pipe 22 is arranged in the recess 29. The polyurethane foam stock solution is foamed, so that the foamed insulation 19 is filled between the outer box 21 and the inner box 31, thereby fixing the vacuum insulation 23 between the outer box 21 and the foamed insulation 19 .

Next, the structure of the vacuum heat insulating material 23 and the heat radiation pipe 22 shown to FIG. 4A is demonstrated with reference to drawings. Here, regarding the vacuum heat insulating material 23 and the heat radiation pipe 22, the state before they are fixed between the foam heat insulating material 19 and the outer box 21 is demonstrated. Fig. 5A is a plan view showing a configuration example of the vacuum heat insulating material and the heat radiation tube shown in Fig. 4A. FIG. 5A shows a state in which the vacuum heat insulating material 23 and the heat radiation pipe 22 are placed inside the side panel 32 in the side view shown in FIG. 1C. Fig. 5B is a cross-sectional view of the part C-C shown in Fig. 5A.

As shown in FIG. 5A, the vacuum heat insulating material 23 has a rectangular shape. In FIG. 5A, if the Z-axis arrow direction is the vertical direction and the Y-axis arrow direction is the horizontal direction, the vacuum heat insulating material 23 is provided with a plurality of recesses 29 for accommodating the heat radiation tube 22 at equal intervals in the vertical direction. As shown in FIG. 5B, the interval between the center lines of the recesses 29 is a dimension W1. In the configuration example shown in FIGS. 5A and 5B, the vacuum heat insulating material 23 is provided with six recesses 29. As shown in FIG. 5A, one heat radiating pipe 22 is arranged to pass through six recesses 29 one by one from the lower side of the vacuum heat insulating material 23 in the longitudinal direction, and return to the lower side of the vacuum heat insulating material 23. The material of the heat radiation pipe 22 is copper, for example. The diameter of the heat radiation pipe 22 is, for example, 4.00 to 5.00 mm.

As shown in FIG. 5B, the recessed part 29 is a recessed shape which has the wall part located on the left and right sides of the heat radiation pipe 22 arrange|positioned. The depth dimension D1 of the recessed part 29 is 5 mm or more, and the width dimension L1 of the recessed part 29 is 40-70 mm. The cross-sectional shape of the recessed portion 29 is quadrangular in the configuration example shown in FIG. 5B, but the cross-sectional shape of the recessed portion 29 is not limited to the quadrangular shape. The cross-sectional shape of the recess 29 may be, for example, a triangle and an ellipse.

In consideration of the error in the manufacturing process of the refrigerator 1, the width dimension L1 of the recessed portion 29 is set with a target dimension and tolerance. Explain the matter specifically. The errors in the manufacturing process of the refrigerator 1 are, for example, manufacturing errors when the vacuum heat insulating material 23 forms the recess 29 and mounting errors when the vacuum heat insulating material 23 is installed on the side panel 32. In addition, when the vacuum heat insulating material 23 is installed on the side panel 32, even if the heat radiating tube 22 is slightly bent along the side panel 32, it is necessary that the heat radiating tube 22 does not extend beyond the recess 29. Taking these errors into consideration, the target size and tolerance of the width dimension L1 of the recessed portion 29 are set to a size that can accommodate the heat radiation pipe 22.

The depth dimension D1 of the recessed portion 29 is set to a dimension greater than or equal to the diameter of the heat radiation pipe 22. Here are the reasons. When the polyurethane foam is foamed, the polyurethane foam pushes the heat radiation pipe 22 to the side panel 32 through the vacuum heat insulating material 23. At this time, there is a possibility that a pressing mark of the heat radiating tube 22 may be generated in the side panel 32, and the outer covering material 25 of the vacuum heat insulating material 23 may be damaged due to the heat radiating tube 22. In order to prevent the occurrence of such indentation and damage, the depth dimension D1 of the recess 29 is set to a dimension greater than or equal to the diameter of the heat radiation tube 22. For example, when the diameter of the heat radiation pipe 22 is 4.0 mm, the depth dimension D1 of the recessed portion 29 is set to 5.0 mm.

Suppose that when the depth dimension D1 of the recess 29 is less than the diameter of the heat radiation pipe 22, the foamed polyurethane foam pushes the heat radiation pipe 22 to the side panel 32 through the vacuum insulation material 23. If the heat radiation pipe 22 The shape of ”appears in the appearance of the side panel 32, and becomes a poor appearance. Therefore, the depth dimension D1 of the recessed portion 29 is set to a dimension greater than or equal to the diameter of the heat radiation tube 22.

Furthermore, referring to FIGS. 5A and 5B, the structure of the vacuum heat insulating material 23 and the heat radiation pipe 22 has been described. The vacuum heat insulating material 15 provided on the side of the back panel 20 shown in FIG. 4A is the same as the vacuum heat insulating material 23 constitute. In addition, although it is not shown in FIG. 4A, a heat radiation tube having the same configuration as the heat radiation tube 22 is also provided on the vacuum heat insulating material 15.

As described with reference to FIGS. 5A and 5B, in the state where the heat radiation tube 22 is housed in the recesses 29 of the vacuum heat insulating materials 15, 23, the vacuum heat insulating material 23 is pasted using a hot melt adhesive, aluminum adhesive tape, etc. It is attached to the side panel 32 and the vacuum heat insulating material 23 is attached to the back panel 20. At this time, when the vacuum insulation material 23 is installed on the side panel 32, it must be temporarily fixed so that the foam insulation material 19 will not penetrate between the side panel 32 and the vacuum insulation material 23 in the subsequent foaming process . When the vacuum heat insulating material 15 is installed on the back panel 20, it must also be temporarily fixed so that the foamed heat insulating material 19 will not penetrate between the back panel 20 and the vacuum heat insulating material 15 during the foaming process.

In the foaming process described with reference to FIG. 3, the foamed heat insulating material 19 is filled in the space formed between the outer box 21 and the inner box 31. In this way, as shown in FIG. 4A, the vacuum heat insulating materials 15 and 23 and the heat radiating tube 22 are fixed between the outer box and the inner box 31.

Next, the method of manufacturing the vacuum heat insulating material 23 shown in FIGS. 5A and 5B will be described with reference to FIGS. 6A and 6B. 6A and 6B are schematic cross-sectional views showing the manufacturing process of the vacuum insulation material shown in FIG. 5A in time sequence.

As shown in FIG. 6A, a laminate 24 in which fiber layers 24a to 24c are laminated is produced. The fibers used in the fiber layers 24a-24c are inorganic fibers such as glass wool, glass fiber, alumina fiber, and silica alumina fiber, but natural fibers such as wood wool may also be used. The horizontal line inside the laminated body 24 of FIG. 6A shows the fiber direction. FIG. 6A shows the case where the thickness of the fiber layers 24a-24c is the same, but the thickness of the fiber layers 24a-24c may also be different. In addition, FIG. 6A shows a case where the laminate 24 has three fiber layers 24a to 24c, but the number of fiber layers is not limited to three. This laminate 24 is referred to as a core material 26 in the vacuum heat insulating material 23 shown in FIG. 5A.

Next, the core material 26 shown in FIG. 6A is housed in the outer cover material 25. The outer cover material 25 is, for example, a metal vapor-deposition laminated film (laminated film) having a plastic layer for thermal welding. The core material 26 is press-processed from the outer cover material 25, and the recessed part 29 shown in FIG. 5A and FIG. 5B is formed in the fiber layer 24a. In FIG. 6B, a part of the six recesses 29 shown in FIG. 5B is shown in the figure. After that, in order to prevent the fibers from protruding from the outer covering material 25, as shown in FIG. 6B, both ends of the outer covering material 25 are welded. In this way, the vacuum heat insulating material 23 having the core material 26 in which the recesses 29 are formed and the outer material 25 covering the core material 26 is produced.

Next, the structure of the door pieces of the drawer compartment in the refrigerator 1 will be described. Since the door pieces 9 to 12 have the same structure, the following description will focus on the structure of the door pieces 11 and 12. Fig. 7A is a front view showing the appearance of the doors of the second freezing compartment and the vegetable compartment shown in Fig. 1A. Fig. 7B is an external perspective view showing an example of the door of the vegetable compartment shown in Fig. 1A.

As shown in FIG. 7A, the door piece 11 and the door piece 12 are arranged to be adjacent to each other up and down. The door panel 11 has an upper plate 37, a bottom plate 38 and a front plate 41. The door panel 11 has side panels and back panels not shown. As shown in FIGS. 7A and 7B, the door panel 12 has an upper plate 39, a bottom plate 40, a back plate 44, a front plate 42 and side plates 47 and 48. The front plate 42 is, for example, a glass plate and a steel plate. Hereinafter, the same reference numerals as the side plates 47 and 48 of the door panel 12 and the back panel 44 are used to describe the side panels and the back panel of the door panel 11.

FIG. 7B shows a case where a support member 58 is mounted on the back plate 44 side of the door panel 12 and a storage box 57 is mounted on the support member 58. FIG. 7B shows the supporting member 58 installed on the right side of the width direction of the door panel 12 (the direction of the X-axis arrow), and the supporting member 58 is also installed on the left side of the door panel 12. A guide 58a parallel to the depth direction (the direction of the Y-axis arrow) is provided on the side surface of the support member 58. In addition, on the upper part of the storage box 57, flanges 57a are provided on both sides in the width direction. The support member 58 supports the flange 57a, thereby mounting the storage box 57 on the support member 58. When the user pulls out the door 12 from the state where the door 12 is closed, the guide 58a slides through a not-shown groove provided in the inner box 31, so that the storage box 57 mounted on the guide 58a is also pulled out . When the storage box 57 is pulled out, the user can put stored items in or take out the storage box 57.

Fig. 8 is a cross-sectional view of the part D-D shown in Fig. 7A. Here, the description will focus on the structure of the door piece 11. As shown in FIG. 8, the upper plate 37 is provided with a main handle 51 that is recessed in the direction of gravity (the direction opposite to the Z-axis arrow). The bottom plate 38 is provided with a sub-handle portion 52 recessed in a direction opposite to the direction of gravity. The sub-handle portion 52 of the door piece 11 and the main handle portion 51 of the door piece 12 are arranged at positions facing each other.

In addition, the space enclosed by the upper plate 37, the bottom plate 38, the back plate 44, the front plate 41, and the side plates 47 and 48 is provided with a vacuum heat insulating material 43, and a foam heat insulating material 19 such as rigid polyurethane foam is filled The gap in that space. As shown in Fig. 8, the upper plate 37 and the bottom plate 38 are provided with ribs 46 that support the vacuum heat insulating material 43, respectively. The vacuum heat insulating material 43 is arranged between the main handle portion 51 and the auxiliary handle portion 52 and the back plate 44. In the configuration example shown in FIG. 8, the lower side of the vacuum heat insulating material 43 is sandwiched and supported by the auxiliary handle 52 and the rib 46. The vacuum heat insulating material 43 is arranged so as to be inclined from the direction perpendicular to the bottom plate 38 (the Z-axis arrow direction) to the back plate 44 side. The vacuum heat insulating material 43 and the vacuum heat insulating material 23 have the same structure, and detailed descriptions thereof are omitted.

In addition, as shown in FIG. 8, the door piece 11 is provided with a gasket 45 that is in close contact with the box body 30 to ensure the airtightness of the vegetable compartment 6. The washer 45 is arranged in the shape of a four-corner frame along the outer periphery of the back plate 44 of the door panel 11 so as to correspond to the front surface of the left side panel 32 of the box 30 shown in FIG. 3 and the right side panel 32 of the box 30 respectively. The front faces of the partition members 49 and 50 shown in FIG. 1A face each other.

Here, with reference to FIG. 8, the functions of the main handle 51, the auxiliary handle 52 and the rib 46 in the procedure of filling the foamed heat insulating material 19 in the door panel 11 will be described. When the foam heat insulating material 19 is filled in the gap between the front plate 41 and the vacuum heat insulating material 43 first, the foam heat insulating material 19 pushes the vacuum heat insulating material 43 to the back plate 44 side. In this case, because the rib 46 supports the vacuum heat insulating material 43, the vacuum heat insulating material 43 is prevented from moving to the back plate 44 side. On the other hand, when the foam heat insulating material 19 is first filled in the gap between the back plate 44 and the vacuum heat insulating material 43, the foam heat insulating material 19 pushes the vacuum heat insulating material 43 to the front plate 41 side. . In this case, the wall on the side of the back plate 44 of the recessed portion in the main handle portion 51 and the sub-handle portion 52 has the function of a rib to support the vacuum heat insulating material 43, and therefore prevent the vacuum heat insulating material 43 from the front plate 41 Move sideways.

As described above, when the foaming process is performed on the door panel 11, the walls on the back plate 44 side of the main handle portion 51 and the auxiliary handle portion 52 and the ribs 46 function to prevent the vacuum heat insulating material 43 from moving. If the walls on the back plate 44 side of the main handle portion 51 and the sub-handle portion 52 are considered to be ribs, the height of the ribs is such that the inner side of the storage is lower than the design surface side. In addition, although the description is based on the case where the foaming process for the door panel 11 is divided into two parts for the front side and the rear side, the foaming process for the front side and the rear side may be performed simultaneously.

9 and 10 are enlarged cross-sectional views of the boundary between the two door pieces shown in FIG. 8. In FIGS. 9 and 10, the foam heat insulation material provided on the door panels 11 and 12 is omitted from the illustration, and the vacuum heat insulation material provided on the door panel 12 is omitted from the illustration.

As shown in FIG. 9, the depth direction (Y-axis arrow direction) length of the sub-handle portion 52 is T2, and the depth direction length of the main handle portion 51 is T1, and the length T2 is shorter than the length T1. That is, the relationship of T1>T2 is present. The length T2 of the depth of the sub-handle portion 52 is, for example, a handle space greater than the average thickness of an adult middle finger. Fig. 9 shows that the length T1 is longer than the length T2 by the length T3. The relationship between the depth length of the main handle portion 51 and the auxiliary handle portion 52 is T1>T2, whereby the auxiliary handle portion 52 is positioned in the projection of the main handle portion 51.

In addition, in the configuration example shown in FIG. 10, the depth from the bottom plate 38 to the uppermost surface of the recessed portion in the sub-handle portion 52 (in the opposite direction to the Z-axis arrow) is H2, and the main handle portion 51 from the opening end to the recessed portion The depth to the bottom surface is H4, and the depth H2 is shallower than the depth H4. The depth H2 of the sub-grip portion 52 is, for example, greater than the depth at the first joint of the average length of the middle finger of an adult. The relationship between the depth H4 and the depth H2 only needs to satisfy H2≦H4. In this case, any one of the main handle 51 and the auxiliary handle 52 has a depth equivalent to the length of the first joint of the average length of an adult's middle finger, so the user can easily hook either Handle part. Furthermore, in the case of H2<H4, when the user hooks his fingers on the main handle 51, the fingers naturally penetrate into the recessed portion due to gravity, thereby creating a sense of peace of mind.

In the configuration example shown in FIG. 10, when the height from the bottom surface of the recessed portion to the uppermost surface of the upper plate 39 of the main handle portion 51 is H1, then H1>H2. The height of (H1-H4) is above the average thickness (T2) of an adult's middle finger. When the height of the opening between the main handle portion 51 of the door piece 12 and the auxiliary handle portion 52 of the door piece 11 is H3, the relationship is H3≧H1-H4≧T2. The reason for setting the size in this way is that an opening is provided on the front side of the main handle 51 so that the user can hook both the main handle 51 and the auxiliary handle 52 with their fingers. Thereby, the space filled with the foam heat insulating material 19 on the front plate 41 side of the sub-handle part 52 in the door panel 11 can be made larger. As a result, the heat insulation performance around the sub-handle portion 52 can be improved.

Furthermore, H1=H2 is also acceptable. In this case, the opening between the main handle portion 51 of the door piece 12 and the auxiliary handle portion 52 of the door piece 11 is equally provided up and down at the boundary between the door piece 11 and the door piece 12. In this case, the effect of improving the heat insulation performance is allocated to the main handle portion 51 of the door panel 12 and the auxiliary handle portion 52 of the door panel 11.

As described above, the sub-handle portion 52 of the upper door piece 11 and the main handle portion 51 of the lower door piece 12 are arranged at positions facing each other, and the height of the opening between the main handle portion 51 and the sub-handle portion 52 is H3 The size above the average thickness of an adult's middle finger. The gap of height H3 serves as a common gap between the auxiliary handle portion 52 of the upper door panel 11 and the main handle portion 51 of the lower door panel 12. From this gap, the user can hook the upper auxiliary handle 52 and lower Any one of the main handle 51 on the side. Therefore, it is not necessary to provide gaps for the user to hook fingers in the auxiliary handle portion 52 and the main handle portion 51 respectively.

In addition, the relationship between the depth and length of the main handle 51 and the auxiliary handle 52 is T1>T2, and the height H3 of the opening between the main handle 51 and the auxiliary handle 52 is greater than the average thickness (T2) of an adult middle finger size. Therefore, the sub-handle portion 52 of the door piece 11 is arranged at a position within the projection of the main handle portion 51 of the door piece 12, and when the user hooks the sub-handle portion 52 of the door piece 11 with his fingers to pull out the door piece 11, And when the main handle 51 of the door panel 12 is hooked with fingers to pull the door panel 12 out, the fingers can be prevented from being caught between the door panel 11 and the door panel 12.

Fig. 11 is an external view showing the upper, front and bottom surfaces of the door of the freezer compartment shown in Fig. 7A. The uppermost layer of FIG. 11 is a top view of the door piece 11, the middle layer is a front view of the door piece 11, and the lower layer is a bottom view of the door piece 11.

As shown in FIG. 11, the length of the width direction (the direction of the X-axis arrow) of the main handle portion 51 is M1 and the length of the width direction of the auxiliary handle portion 52 is M2, and the width length M1 is longer than the width length M2. That is, the relationship of M1>M2 is present. The relationship between the widths of the main handle portion 51 and the sub-handle portion 52 is M1>M2. As described with reference to FIG. 9, the relationship between the depths of the main handle portion 51 and the sub-handle portion 52 is T1>T2. Therefore, the sub-handle portion 52 is located in the projection of the main handle portion 51.

In addition, as shown in FIG. 11, the recessed shapes of the main handle portion 51 and the sub-handle portion 52 exhibit line symmetry with respect to the center line 55. The depth length of the recessed shape of the main handle portion 51 is the longest at the position of the center line 55, and the shorter the distance from the center line 55 in the width direction. The length of the depth of the recessed shape of the sub-handle portion 52 is also the longest at the position of the center line 55, and is shorter as it is farther from the center line 55 in the width direction.

Both the main handle 51 and the auxiliary handle 52 have the longest depth at the position of the center line 55. When the user hooks the main handle 51 and the auxiliary handle 52 with his fingers, it is easy to use his fingers. Hook around the center of these handles. On the other hand, the storage boxes 57 of the drawer compartments such as the second freezing compartment 5 and the vegetable compartment 6 move back and forth together with the door pieces. Therefore, if the user pulls out the door panel near the center of the handle with fingers, the pulling force is applied to the width direction of the door panel evenly, and the storage box 57 with the storage can be pulled out from the inner box 31 smoothly. . Furthermore, because M1>M2, the sub-handle portion 52 is located in the projection of the main handle portion 51, thereby preventing the fingers from being caught at both ends of the door panels 11 and 12 in the width direction.

Next, the rib 46 and the vacuum heat insulating material 43 provided inside the door panel 11 will be described. Here, the door piece 11 provided with the vacuum heat insulating material 43 is demonstrated. Fig. 12 is a plan view of the part of the line E-E shown in Fig. 11 viewed from the back side of the refrigerator. 13A and 13B are diagrams for explaining the arrangement of the vacuum insulation material in the door panel shown in FIG. 8.

In the configuration example shown in FIG. 12, two ribs 46 are provided on the upper plate 37 and two ribs 46 are provided on the bottom plate 38. If a plurality of ribs 46 are provided on one or both of the upper plate 37 and the bottom plate 38, even if the pressure applied by the foamed heat insulating material 19 to the vacuum heat insulating material 43 is uneven during the foaming process, the vacuum heat insulating material 43 is It is also possible to prevent the vacuum heat insulating material 43 from shifting in position when a part is subjected to strong pressure.

The height of the vertical direction (the direction of the Z-axis arrow) of each rib 46 shown in FIG. 12 is Lc, and the height of the vacuum heat insulating material 43 is Lb, then the total height of the upper rib 46 and the lower rib 46 ( 2×Lc) is smaller than the height Lb of the vacuum heat insulating material 43. In addition, the length of the rib 46 in the width direction (the direction of the X-axis arrow) is Le and the length of the vacuum heat insulating material 43 in the width direction is Ld, and the sum of the widths of the two ribs 46 (2×Le) is smaller than the vacuum barrier The width Ld of the heating material 43.

The sum of the widths of the two ribs 46 (2×Le) is shorter than the width Ld of the vacuum insulation material 43. Therefore, when the polyurethane foam stock solution flows into the gap in the door sheet during the foaming process, it can suppress its impact This obstruction of the flow ensures the flow path of the polyurethane foam stock solution. As a result, it is possible to suppress the occurrence of insufficient filling of the polyurethane foam. In addition, at the end of the door panel production process, the operator assembles the upper plate 37 and the bottom plate 38 during the door frame work, and as long as the side panel 47 or the side panel 48 is installed, the vacuum can be insulated from the side of the door panel 11 The material 43 is assembled in. At this time, the total height (2×Lc) of the two ribs 46 is shorter than the height Lb of the vacuum heat insulating material 43. Therefore, the friction area between the vacuum heat insulating material 43 and the rib 46 is small, and the operator can easily remove the vacuum heat insulating material. 43 is assembled into the door piece 11. Furthermore, it is possible to reduce the risk of breakage of the outer cover material 25 of the vacuum heat insulating material 43 due to friction with the rib 46.

Next, similar to FIG. 8, the vacuum heat insulating material 43 shown in FIG. 12 will be described based on a view from the side plate 48 side of the door panel 11. As shown in FIG. 8, the vacuum heat insulating material 43 is arranged so as to be inclined from a direction perpendicular to the bottom plate 38 to the back plate 44 side in the door panel 11.

FIG. 13A shows that the plane of the vacuum heat insulating material 43 is placed parallel to the vertical direction (the direction of the Z-axis arrow) with respect to the ground. At this time, the vertical height of the vacuum heat insulating material 43 is La, and the thickness of the vacuum heat insulating material 43 is Ta. When the vacuum heat insulating material 43 shown in FIG. 13A is inclined at an angle θ from the vertical direction, it becomes as shown in FIG. 13B. At this time, the thickness of the vacuum heat insulating material 43 in the horizontal direction is Ta/sinθ. That is, the thickness of the vacuum heat insulating material 43 in the horizontal direction increases depending on the magnitude of the inclination angle θ. In addition, the height Lb shown in FIG. 12 and the height La shown in FIG. 13A have a relationship of Lb<La.

In the first embodiment, the vacuum heat insulating material 43 is provided in the door panel 11 as shown in FIG. 13B. By arranging the vacuum heat insulating material 43 in the door panel 11 obliquely from the vertical direction, the vacuum heat insulating material 43 having a greater height La can be installed in the door panel 11. In addition, as described with reference to FIG. 13B, the thickness of the vacuum heat insulating material 43 in the horizontal direction increases. Therefore, compared with the case shown in FIG. 13A, the amount of the vacuum heat insulating material 43 mounted on the door panel 11 increases, and heat insulation performance improves.

In addition, the case where two ribs 46 are provided on the upper plate 37 and the bottom plate 38 has been described with reference to FIG. 12. The number of ribs 46 provided on one or both of the upper plate 37 and the bottom plate 38 is not limited to two. It may be one or three or more. When the number of ribs 46 provided on one or both of the upper plate 37 and the bottom plate 38 is one, the width Le shown in FIG. 12 may be elongated, and the rib 46 may be arranged at the center of the width Ld. For example, when the number of ribs 46 provided on the upper plate 37 and the bottom plate 38 is one, Le>(1/2)Ld.

In addition, regarding the height of the rib 46, the rib 46 of the upper plate 37 and the rib 46 of the bottom plate 38 may be different. For example, the height of the rib 46 of the upper plate 37 is made higher than the height of the rib 46 of the bottom plate 38. In this case, as shown in FIG. 13B, even if the vacuum heat insulating material 43 is inserted into the door panel obliquely from the vertical direction, the vacuum heat insulating material 43 can be prevented from falling off the upper rib 46 and falling onto the back plate 44. In addition, by reducing the height of the rib 46 of the bottom plate 38, when the operator inserts the vacuum insulation material 43 into the door panel 11 in the door panel manufacturing process, it is easy to fit the lower end of the vacuum insulation material 43 to the ribs. Between part 46 and the auxiliary handle part 52.

The refrigerator of the first embodiment includes a box body 30 provided with a heat insulating material between an outer box 21 and an inner box 31, and a drawer compartment provided in the inner box 31 and having an opening at the front. It can be moved in the front and rear directions. The door pieces 9-12 that open and close the opening of the drawer compartment have a main handle 51 provided on the upper side and a sub-handle 52 provided on the lower side.

According to the first embodiment, the handles are provided on both the upper and lower sides of the drawer-type door pieces 9-12. Therefore, the user can easily hook the handles with his fingers without being affected by the height, reducing opening and closing operations Burden. A user with a short height can easily hook the sub-handle 52 on the lower side with his fingers, and a user with a taller height can easily hook the main handle 51 on the upper side with his fingers. In addition, if it is a user with an average height of an adult, it is easy to hook any one of the upper main handle 51 and the lower sub handle 52 with a finger. A user who is tall but sitting on a chair can easily hook the sub-handle 52 on the lower side with his fingers. In this way, users from short children to tall adults, regardless of their height and posture, can hook and buckle the door with their hands, and can easily open and close the door, regardless of their height and posture.

In the past, when the user removed the door to clean the drawer compartment, etc., the door was pulled out by hooking the handle with his hand, but it was difficult to hold the door with only one handle. Therefore, when the user wants to lean on the handle at one place and carry the door away, there is a risk of the door falling off. Compared with other materials, when the door piece is made of glass, the weight of the door piece is heavier, making the risk higher. If the user drops the glass door, the door will be damaged. Even if the handles are provided on both sides of the door piece, it is difficult for the user to hold the door piece when holding it horizontally, making the door piece easy to fall. In contrast, in the refrigerator of the first embodiment, handles are provided on the upper and lower sides of the door of the drawer compartment. Therefore, the user can pinch the door from the upper and lower sides of the door to stably grasp the door. . Therefore, the risk of the user dropping the door piece can be reduced.

In the first embodiment, the door panel 12 of the drawer compartment is composed of an upper plate 39, a bottom plate 40, a back plate 44, a front plate 42, and side plates 47 and 48. The upper plate 39 is provided with a main handle 51 and the bottom plate 40 is provided with a sub Handle 52. Therefore, the appearance design of the front panel 42 is not affected, and the appearance design is not restricted.

In addition, in the first embodiment, the sub-handle portion 52 has a shape recessed upward in the bottom plate 40. The recessed shape is not provided on the front plate 42, so the design of the front plate 42 is not restricted. In addition, since the recessed shape is not provided on the back plate 44, the back plate 44 can be prevented from protruding to the inside of the library.

In addition, in the first embodiment, when the drawer-type door panels 11 and 12 are arranged adjacent to each other up and down, the sub-handle part 52 of the upper door panel 11 and the main handle part 51 of the lower door panel 12 are arranged at Positions facing each other. A common gap is provided between the upper auxiliary handle portion 52 and the lower main handle portion 51. Therefore, the user can use this gap to hook the upper auxiliary handle portion 52 and the lower main handle portion 51 with fingers. Any one of.

In addition, in the first embodiment, the depth T2 of the sub-handle portion 52 is shorter than the depth T1 of the main handle portion 51, and the height H3 of the opening between the main handle portion 51 and the sub-handle portion 52 is the sub-handle portion. 52 depth length T2 (average thickness of adult middle finger) or more. Therefore, the secondary handle 52 of the door 11 is arranged at a position within the projection of the main handle 51 of the door 12. When the user hooks the secondary handle 52 of the door 11 and the main handle of the door 12 with fingers When any one of the parts 51 pulls the door leaf apart, it is possible to prevent fingers from being caught between the door leaf 11 and the door leaf 12.

In addition, in the first embodiment, the depth H2 of the depression from the bottom plate 38 of the sub-handle portion 52 of the door panel 11 may be shallower than the depth H1 of the depression from the upper plate 39 of the main handle part 51 of the door panel 12. In this case, an opening is provided on the front surface of the door panel 12 on the side of the main handle portion 51, and the space filled with the foam insulation 19 can be secured on the side of the front plate 41 of the auxiliary handle portion 52 in the door panel 11, and Improve the heat insulation performance around the sub-handle 52.

In addition, in the first embodiment, the upper plate 37 and the bottom plate 38 of the door panel 11 are provided with ribs 46 for supporting the vacuum heat insulating material 43. The vacuum insulation material 43 assembled in the door panel is not fixed to either the front plate 41 on the design side and the back plate 44 on the inner side of the library, but is supported by the rib 46. In the past, when fixing the vacuum heat insulating material in the door panel, auxiliary materials such as tape were necessary. However, in the first embodiment, auxiliary materials such as tape are not required, which can simplify the manufacturing process and reduce the manufacturing cost.

In addition, in the first embodiment, the length of the upper rib 46 and the lower rib 46 in the width direction is shorter than the length of the vacuum heat insulating material 43 in the width direction. In this case, in the foaming process, when the polyurethane foam stock solution flows through the gap in the door piece, it can suppress the obstruction of the flow and ensure the flow path of the polyurethane foam stock solution. As a result, it is possible to suppress the occurrence of insufficient filling of the polyurethane foam.

In addition, in the first embodiment, the total height of the upper rib 46 and the lower rib 46 is smaller than the height of the vacuum heat insulating material. In this case, when the operator assembles the vacuum heat insulation material 43 from the side of the door panel 11, the friction area between the vacuum heat insulation material 43 and the rib 46 is small, and it is easy to assemble the vacuum heat insulation material 43 into the door panel 11. . Furthermore, it is possible to reduce the risk of breakage of the outer cover material 25 of the vacuum heat insulating material 43 due to friction with the rib 46.

In addition, in the first embodiment, the upper rib 46 and the lower rib 46 are provided on the side of the back plate 44 rather than the main handle 51 and the auxiliary handle 52. Therefore, the vacuum heat insulating material 43 is arranged on the side of the back plate 44 rather than the main handle portion 51 and the sub-handle portion 52, and the vacuum heat insulating material 43 can be assembled into the door panel instead of being directly attached to the design surface side. The rib 46 is positioned away from the front plate 41 of the design surface and is closer to the inside of the library. Therefore, the vacuum heat insulating material 43 is not arranged in close contact with the design surface. As a result, the irregularities on the surface of the vacuum heat insulating material 43 are not transferred and displayed on the design surface, and it is possible to prevent them from deteriorating the appearance. In addition, by arranging the vacuum insulation material 43 inside the library, the heat intrusion into the library is reduced, and a better energy-saving effect is expected.

In addition, in the first embodiment, the foam heat insulating material 19 is filled between the front plate 41 and the vacuum heat insulating material 43 and between the back plate 44 and the vacuum heat insulating material 43. Not only is the vacuum heat insulating material 43 and the front plate 41 separated, but also the foamed heat insulating material 19 is filled between the vacuum heat insulating material 43 and the front plate 41, so that the heat intrusion into the compartment can be further reduced.

In the first embodiment, a plurality of ribs 46 may be provided on one of the upper plate 37 and the bottom plate 38 of the door panel 11. In this case, in the foaming process, even if the pressure from the foamed heat insulating material 19 received by the vacuum heat insulating material 43 varies, it is possible to prevent the vacuum heat insulating material 43 from shifting in position.

In addition, in the first embodiment, the vacuum heat insulating material 43 may be arranged to be inclined from a direction perpendicular to the bottom plate 38. In this case, even if the size of the entire door panel 11 is not changed, the vacuum heat insulating material 43 having a greater height can be installed in the door panel 11. Compared with the case where the vacuum heat insulating material 43 is arranged perpendicular to the bottom plate 38, as a result, the amount of the vacuum heat insulating material 43 mounted on the door panel 11 increases, and the heat insulation performance improves.

In recent years, in order to improve energy-saving performance, the amount of vacuum heat insulating materials in refrigerators has increased, and vacuum heat insulating materials have also been assembled in door panels. The arrangement method of this vacuum insulation material will affect energy-saving performance and manufacturing cost. In the past, because of the shape of the handle portion, the insulation wall of the door panel became thinner. Therefore, the heat intrusion from the door sheet into the library is large, which has a negative impact on energy-saving performance. Moreover, even if it is desired to increase the coverage of the vacuum insulation material in the door panel, the size of the vacuum insulation material assembled in the door panel is limited because the vacuum insulation material and the handle part interfere with each other.

For example, there is known a refrigerator (for example, Patent Document 3) in which a vacuum heat insulating material is arranged in close contact with the front plate of a door panel, and handles are provided on both sides of the vacuum heat insulating material. Because the handles are provided on both sides of the vacuum heat insulating material, the horizontal dimension of the vacuum heat insulating material assembled into the door panel is restricted. As a result, the amount by which the vacuum heat insulating material becomes shorter in the lateral direction is the amount of the depth of the handle. In addition, simply adding the handle to the door panel will reduce the thickness of the vacuum insulation material in the handle. In this case, energy-saving performance will deteriorate. On the other hand, the vacuum heat insulating material is directly attached to the design surface side, so that the surface irregularities of the vacuum heat insulating material may be transferred to the design surface of the door panel. Attaching the vacuum heat insulation material to the front panel may cause deterioration in appearance design and increase manufacturing costs and operating time.

On the other hand, in the refrigerator of this Embodiment 1, as mentioned above, the vacuum heat insulating material 43 is arrange|positioned between the handle part in a door piece and the inside of a refrigerator. In the past, the thickness of the heat-insulating material on the back side of the handle was thinner, and there was a concern about heat insulation performance. However, in the first embodiment, the back side of the handle is covered with a vacuum heat-insulating material, which can reduce the heat to the interior Invade. Furthermore, in the first embodiment, the vacuum heat insulating material 43 is arranged obliquely, the size of the vacuum heat insulating material 43 can be increased, and the coverage rate of the vacuum heat insulating material 43 on the front surface of the door panel can be improved.
