[0009] Hereinafter, the embodiments of the present disclosure will be described with reference to the accompanying drawings. In the following description, the same reference numerals are assigned to the same components. Their names and functions are also the same. In the following description, the directions such as front, back, left, and right refer to the directions observed from the user using the refrigerator.

[0010] In the present embodiment, a refrigerator 1 having more than one cooling chamber is listed as an example for explanation. In the present disclosure, "refrigerator" refers to all refrigeration equipment that has an internal space (cooling chamber) whose temperature is lower than the outside air temperature and can reduce the temperature of the stored items. The refrigerator can be, for example, a cold storage or a freezer. The refrigerator can have only one cooling chamber or multiple cooling chambers. In the case where the refrigerator has multiple cooling chambers, the multiple cooling chambers can also include at least two of a cold storage chamber, a freezer chamber, a vegetable chamber, a zero-degree chamber, a partial freezer chamber, and the like.

[0011] (Overall structure of refrigerator) First, the overall structure of the refrigerator 1 according to the present embodiment will be described. Figure 1 , the appearance of the refrigerator 1 as viewed from the front is shown. Figure 22 shows the appearance of the refrigerator 1 when viewed from the front oblique direction.

[0012] The refrigerator 1 has a housing 50. The housing 50 may be, for example, a heat-insulating housing. The "heat-insulating housing" refers to a housing having a wall portion made of a heat-insulating material.

[0013] The housing 50 has a cooling chamber. The cooling chamber is a chamber for cooling items. The cooling chamber is open to the front. In this embodiment, the housing 50 has a plurality of cooling chambers. For example, the housing 50 has three cooling chambers, namely, a refrigerating chamber, a vegetable chamber, and a freezing chamber, in order from the top.

[0014] The refrigerator 1 includes a drawer 10, which is provided on the housing 50 in a pull-out manner. In the present embodiment, the refrigerator 1 has a plurality of drawers 10A and 10B. The drawer 10A is arranged at the middle section of the housing 50, for example, forming a vegetable compartment. The drawer 10B is arranged at the lower section of the housing 50, for example, forming a freezer compartment.

[0015] The drawer has a front panel that closes at least a portion of the opening of the cooling chamber. For example, the drawer 10A has a vegetable compartment door 12 as an example of a front panel. In addition, the drawer 10B has a freezer compartment door 13 as an example of a front panel. The vegetable compartment door 12 and the freezer compartment door 13 are insulated doors having a heat insulating material.

[0016] A refrigerator door 11 is provided in the uppermost cooling room (eg, refrigerator compartment) of the refrigerator 1. The refrigerator door 11 is attached to the housing 50 so as to be openable and closable from both sides. The refrigerator door 11 is preferably an insulating door having a heat insulating material.

[0017] In the present embodiment, the surface provided with the front panel or door is referred to as the front face or the front face of the refrigerator. Furthermore, with the front face as a reference, the surfaces of the refrigerator 1 are set as the top face, the side face, the back face, and the bottom face based on the position when the refrigerator 1 is set in the normal state. In addition, when the refrigerator 1 is placed on the setting surface, the left and right direction when observing the refrigerator 1 from the front face is referred to as the left and right direction (or the width direction) of the refrigerator 1 (or the vegetable compartment door 12, the freezer compartment door 13, etc.). In addition, when the refrigerator 1 is placed on the setting surface, the up and down direction of the refrigerator 1 is referred to as the up and down direction (or the height direction) of the refrigerator 1 (or the vegetable compartment door 12, the freezer compartment door 13, etc.). In addition, when the refrigerator 1 is placed on the setting surface, the front and back directions of the refrigerator 1 are referred to as the front and back directions (or the depth direction) of the refrigerator 1 (or the vegetable compartment door 12, the freezer compartment door 13, etc.). In addition, the side located on the left side when viewed from the front side of the refrigerator 1 is called the left side of the refrigerator 1 (or the vegetable compartment door 12, the freezer door 13, etc.), and the side located on the right side when viewed from the front side of the refrigerator 1 is called the right side of the refrigerator 1 (or the vegetable compartment door 12, the freezer door 13, etc.).

[0018] In this embodiment, an upper cover 40 is provided at the upper end of the pulled-out front panel (e.g., the vegetable compartment door 12 and the freezer compartment door 13). The upper cover 40 forms the upper surface 140 of the front panel. The upper cover 40 is used as a handle for the user to hang his hand when pulling the drawers 10A and 10B out to the front.

[0019] (Drawer structure) Next, a more detailed structure of the drawer 10 provided in the refrigerator 1 is described. As described above, the refrigerator 1 of this embodiment has two drawers (specifically, drawers 10A and 10B). These drawers have substantially the same structure. Therefore, below, each drawer 10A and 10B is represented and described as the drawer 10.

[0020] Figure 3 1 shows the appearance of the drawer 10. The drawer 10 has a front panel 100 and a container 20. The front panel 100 blocks at least a portion of the opening of the cooling chamber. Figure 1 In the refrigerator 1 shown in FIG. 1 and FIG. 2 , a vegetable compartment door 12 and a freezer compartment door 13 are shown as examples of the front panel 100 .

[0021] The front panel 100 is relatively displaceable in the front-rear direction relative to the housing. The container 20 is mounted on the front panel 100. The container 20 is open upward. The container 20 and the front panel 100 are relatively displaceable in the front-rear direction relative to the housing.

[0022] The front panel 100 has a front surface 110, a pair of side surfaces 120, 130, and an upper surface 140. In this embodiment, the front surface 110, the pair of side surfaces 120, and 130 are formed by a single metal plate. In addition, the upper surface 140 is formed by an upper cover 40 made of resin. The upper cover 40 is mounted on the upper end of the metal plate.

[0023] The front face 110 extends in the height direction and the width direction. The front face 110 may be formed of a flat surface or a curved surface having a curvature in at least one of the height direction and the width direction. The side face 120 is connected to one side of the front face 110 in the width direction. The side face 120 extends backward from the front face 110. The side face 130 is connected to the other side of the front face 110 in the width direction. The side face 130 extends backward from the front face 110.

[0024] (Configuration of the top of the front panel) Next, a more detailed structure of upper surface 140 of front panel 100 will be described. Figure 4 , Figure 5 , Figure 6 The outer appearance of the upper cover 40 on which the upper surface 140 of the front panel 100 is formed is shown.

[0025] Figure 7 and Figure 84 and 4 show the cross-sectional structure of the upper cover 40 in the width direction. Specifically, Figure 7 yes Figure 5 The cross-sectional view of the upper cover 40 along the line VII-VII is shown. Figure 8 yes Figure 6 1 and 2. A cross-sectional view of the upper cover 40 taken along line VIII-VIII is shown.

[0026] Fig. 9 The configuration of the cross section in the direction intersecting the width direction of the upper cover 40 is shown. Fig. 9 From left to right, Figure 5 The upper cover 40 is shown with reference to the cross sections along the lines IXA-IXA, IXB-IXB, and IXC-IXC.

[0027] The top 140 is provided on the upper side of the front 110 and the pair of side surfaces 120 and 130. The top 140 is connected to the upper edge of the front 110 and the upper edges of the pair of side surfaces 120 and 130, respectively. The top 140 may also be composed of a plane portion or a curved portion. In the present embodiment, the top 140 has a plane portion 141 and an inclined surface 142. The plane portion 141 is a substantially horizontal plane. The inclined surface 142 is located closer to the front side than the plane portion 141. The inclined surface 142 connects the front end edge of the plane portion 141 and the upper edge of the front 110. The inclined surface 142 extends obliquely downward toward the front side. The inclined surface 142 may be a curved surface, but in the present embodiment, it is a plane.

[0028] The recessed portion 200 is formed on the inclined surface 142. The recessed portion 200 is provided on substantially the entire width direction of the inclined surface 142. In other words, the recessed portion 200 is provided from one end portion to the other end portion in the width direction of the inclined surface 142. The planar portion of the inclined surface 142 where the recessed portion 200 is not provided is located on the rear side of the outer end portion of the recessed portion 200 in the width direction.

[0029] The concave portion 200 includes a front portion 210, a back portion 220, a first side portion 230, a second side portion 240, and a bottom portion 250. The front portion 210 is located at the front side of the concave portion 200. The back portion 220 is located at the rear side of the concave portion 200. One end portion in the width direction of the front portion 210 (for example, the end portion on the left side when viewed from the front) and one end portion in the width direction of the back portion 220 (for example, the end portion on the left side when viewed from the front) are connected by the first side portion 230. The other end portion in the width direction of the front portion 210 (for example, the end portion on the right side when viewed from the front) and the other end portion in the width direction of the back portion 220 (for example, the end portion on the right side when viewed from the front) are connected by the second side portion 240. The bottom portion 250 is located at the lower side of the concave portion 200. The bottom portion 250 is connected to the lower ends of the front portion 210, the back portion 220, the first side portion 230, and the second side portion 240.

[0030] The front portion 210 is formed of a curved surface that is convex upward toward the upper side, more specifically, toward the rear (see Fig. 9 ). The front end of the front portion 210 is substantially horizontal. The lower end of the front portion 210 extends substantially in the height direction. The curvature of the cross section of the front end of the front portion 210 along the height direction and the depth direction is greater than the curvature of the same cross section of the lower end of the front portion 210.

[0031] The back portion 220 extends to the upper side of the front portion 210, the first side portion 230 and the second side portion 240. In other words, the back portion 220 includes a portion located on the upper side compared to the front portion 210, the back portion 220, and the recessed portion 200 surrounded by the first side portion 230 and the second side portion 240. The back portion 220 is not located at least at both ends in the width direction at the rear end portion of the inclined surface 142. On the other hand, the back portion 220 is substantially located in the entire width direction at the front end portion of the inclined surface 142. The size of the back portion 220 in the width direction gradually increases toward the front side. At the center of the front-to-back direction of the inclined surface 142, on the inclined surface 142, an area where the back portion 220 is not provided exists at both ends in the width direction.

[0032] The back portion 220 includes two first back portions 221a, 221b and a second back portion 222. The second back portion 222 is located in the center in the width direction, and the two first back portions 221a, 221b are located on the outside of the width direction relative to the second back portion 222. The first back portion 221a is connected to one end portion of the second back portion 222 in the width direction (for example, the end portion on the left side when viewed from the front). One end portion of the first back portion 221a in the width direction is connected to the first side portion 230, and the other end portion is connected to the second back portion 222. The first back portion 221b is connected to the other end portion of the second back portion 222 in the width direction (for example, the end portion on the right side when viewed from the front). One end portion of the first back portion 221b in the width direction is connected to the second back portion 222, and the other end portion is connected to the second side portion 240.

[0033] The first back surface portions 221a, 221b and the second back surface portion 222 are curved surfaces having curvature in the height direction (see Fig. 9 ). Therefore, in this embodiment, the back portion 220 is generally composed of a curved surface having a curvature in the height direction. The central portion 220a in the height direction of the back portion 220 has a relatively low curvature, and the upper portion 220b and the lower portion 220c have relatively high curvatures compared to the central portion 220a (for example, see Fig. 9 IXA-IXA cross section). The curvature of each of the upper portion 220b and the lower portion 220c along the height direction is higher than the curvature of the central portion 220a along the height direction. In this embodiment, the curvature of the central portion 220a along the height direction is substantially zero.

[0034] The first back side 221a, 221b extends from the center side in the width direction (the second back side 222 side) toward the outer side in the width direction toward the front side. The curvature of the first back side 221a, 221b along the width direction is not constant in the width direction, but becomes higher toward the outer side in the width direction. The curvature of the first back side 221a, 221b along the width direction is higher than the curvature of the second back side 222 along the width direction.

[0035] Specifically, the curvature of at least a portion of the first back surface portion 221a, 221b along the width direction is greater than the curvature of the second back surface portion 222 along the width direction (see Figure 8). In other words, the first back portion 221a, 221b includes a portion whose curvature along the width direction is higher than the curvature along the width direction of the second back portion 222. In the present embodiment, the curvature in the width direction of at least the outer end portion along the width direction of the first back portion 221a, 221b is higher than the curvature in the width direction of the second back portion 222. In more detail, in the present embodiment, the second back portion 222 does not substantially have a curvature in the width direction. That is, the second back portion 222 is substantially flat in the entire width direction. In contrast, the first back portion 221a, 221b substantially has a curvature in the width direction as a whole. Thus, the curvature of the first back portion 221a, 221b along the width direction as a whole is higher than the curvature of the second back portion 222 in the width direction.

[0036] The outer end (front end) of the back portion 220 extends in a generally front-to-back direction. The outer end (rear end) of the front portion 210 extends in a generally front-to-back direction. The outer ends on both sides of the width direction of the back portion 220 are connected to the outer ends on both sides of the width direction of the front portion 210 via the first side portion 230 or the second side portion 240. When viewed from above, the first side portion 230 and the second side portion 240 are respectively configured to widen in width toward the outside in the width direction. The curvature of the width direction of the central portion of each of the first side portion 230 and the second side portion 240 along the width direction is relatively large, and the curvature of the width direction of the two side portions along the width direction is relatively small. Therefore, the first side portion 230 and the second side portion 240 are respectively convex toward the upper side (refer to Figure 7 ).

[0037] The bottom portion 250 is connected to the lower end of each of the front portion 210, the back portion 220, the first side portion 230, and the second side portion 240. The bottom portion 250 is formed of a concave surface protruding toward the lower side. That is, the bottom portion 250 is inclined upward toward the outer side in the width direction (refer to Figure 7 ).

[0038] The bottom surface 250 is tangent to the front surface 210, the back surface 220, the first side surface 230, and the second side surface 240. The portion with the largest curvature in the depth direction on the surface of the recessed portion 200 is the bottom surface 250 (see Fig. 9 ). The bottom portion 250 has a curvature along the width direction. In a cross section including the center of the depth direction of the bottom portion 250 and along the width direction and the height direction, the bottom portion 250 has a curvature along the width direction and is substantially formed by a concave parabola protruding downward (see Figure 7). In the cross section including the center of the bottom portion 250 in the width direction and along the depth direction and the height direction, the bottom portion 250 has a curvature in its entirety and is substantially formed by a concave parabola protruding downward (for example, see Fig. 9 IXA-IXA section).

[0039] The bottom surface 250 includes first bottom surfaces 251a and 251b connected to the first back surfaces 221a and 221b and a second bottom surface 252 connected to the second back surface 222. Of the first bottom surfaces 251a and 251b and the second bottom surface 252, at least the first bottom surfaces 251a and 251b are convex downward.

[0040] Specifically, in this embodiment, both the first bottom surface 251a, 251b and the second bottom surface 252 are convex downward. Moreover, the curvature of the first bottom surface 251a, 251b along the width direction is higher than the curvature of the second bottom surface 252 along the width direction (see Figure 7 ). At the boundary between the first bottom surface 251a and the second bottom surface 252, the curvature changes continuously. Similarly, at the boundary between the first bottom surface 251b and the second bottom surface 252, the curvature changes continuously. Figure 7 As shown, the bottom surface portion 250 is substantially composed of a concave smooth curved surface that protrudes downward in the width direction.

[0041] Fig.10 The left side portion of the upper cover 40 is shown. Fig.10 , a virtual line L is shown by a dotted line. The virtual line L is a line connecting the lowest point P of the recess 200 in the cross section along the front-rear direction and the height direction of the upper cover 40. That is, the virtual line L can also be called a line indicating the valley line of the recess 200.

[0042] Fig.11 , the cross-sectional shape of the recess 200 along the direction perpendicular to the imaginary line L is shown. Fig.11 From left to right, Fig.10 The structures of the cross sections of the upper cover 40 taken along the lines XIA-XIA, XIB-XIB, XIC-XIC, and XID-XID.

[0043] The upper surface 140 of the upper cover 40 has a bilaterally symmetrical shape. The shape of the recessed portion 200 from the center of the upper cover 40 to the right side can also be applied to the same configuration as the left side.

[0044] The first back surface 221a, 221b and the first side surface 230 or the second side surface 240 are composed of a continuous curved surface, and the curvature of the continuous curved surface along the direction perpendicular to the imaginary line L extending forward toward the outside in the width direction in a plan view becomes smaller toward the outside in the width direction. In other words, the first back surface 221a, 221b and the first side surface 230 or the second side surface 240 have an imaginary line L, and the curvature of the first back surface 221a, 221b and the first side surface 230 or the second side surface 240 in the direction perpendicular to the imaginary line L becomes smaller toward the outside in the width direction. In the cross section along the direction perpendicular to the imaginary line L and the height direction, the portion directly above the imaginary line L of the first back surface 221a, 221b and the first side surface 230 or the second side surface 240 is substantially horizontal.

[0045] For example, in Fig.11 In the example shown, the curvature of the concave surface of the concave portion 200 in the XID-XID line cross section shown on the far right is the largest, and the curvature of the concave surface gradually decreases toward the left. Also, the curvature of the concave surface of the concave portion 200 in the XIA-XIA line cross section shown on the far left is the smallest.

[0046] In addition, if Fig.10 As shown, in a plan view, the first back surface portions 221a and 221b are connected to the second back surface portion 222 on the surface of the recess 200 and are located behind the lowest portion of the bottom surface portion 250 located on the lower side of the recess 200 (i.e., the position of the imaginary line L).

[0047] The concave portion 200 surrounded by the front portion 210, the back portion 220, the first side portion 230, and the second side portion 240 is located below the center of the inclined surface 142 in the height direction (see Fig. 9 The recessed portion 200 is not located on the upper side of the inclined surface 142 in the height direction, and only the rear surface portion 220 , the first side surface portion 230 , and the second side surface portion 240 are located on the upper side of the inclined surface 142 in the height direction.

[0048] At substantially the upper end of the recess 200, the curvature of the back portion 220 located at both ends of the recess 200 in the width direction is greater than the curvature of the front portion 210 in the width direction. Figure 8As shown, at the substantially upper end of the recess 200, both ends of the back portion 220 in the width direction are located at the front side of the central portion in the width direction, and extend toward the outer side in the width direction toward the front side. At the substantially upper end of the recess 200, the outermost end in the width direction of the recess 200 is located at the front side of the center in the front-rear direction of the recess 200. The recess 200 is configured so that the outermost end in the width direction of the recess 200 is located at the rear side as it goes downward. At the lower end of the recess 200, the outermost end in the width direction of the recess 200 is located at the substantially center in the front-rear direction.

[0049] The lower end of the recess 200 is substantially line-symmetrical with respect to a straight line L2 passing through the center of the recess 200 in the width direction and the front-rear direction and extending in the width direction (for example, see Fig. 9 On the other hand, at the end of the recess 200, a shape that is asymmetric with respect to the straight line L2 is formed (for example, referring to Fig. 9 The lowest point P of the recess 200 is located at a position forward of the center of the recess 200 in the front-rear direction at any position in the width direction (refer to Fig. 9 ).

[0050] As described above, the refrigerator 1 of this embodiment includes: a housing 50 having a cooling chamber opened toward the front; and a drawer 10 installed in a manner that can be displaced in the front-rear direction relative to the housing 50, and having a front panel 100 that closes the opening of the cooling chamber. The front panel 100 has an upper surface 140 formed with a recessed portion 200. The recessed portion 200 is used as a handle for a user to hang his hand when pulling the drawer 10 out to the front.

[0051] The recessed portion provided in the handle portion of the door of the existing refrigerator is composed of a flat wall surface, and is generally straight and angular (uneven) in shape. In such a shape, it is difficult to remove the garbage trapped in the recessed portion. In particular, garbage or dust is easily accumulated in the angular corners of the recessed portion, and it is difficult to remove them.

[0052] On the other hand, the recessed portion 200 of the front panel 100 of the drawer 10 of the present embodiment has a bottom portion 250 located at the lower side. The back portion 220 located at the rear side of the bottom portion 250 in the surface of the recessed portion 200 includes a first back portion 221a, 221b and a second back portion 222, and the second back portion 222 is located at a position closer to the center in the width direction than the first back portion, and is connected to the first back portion 221a, 221b. And, the bottom portion 250 is inclined upward toward the outer side of the width direction. In addition, the first back portion 221a, 221b extends from the central side of the width direction toward the outer side to the front side, and, when viewed from above, the curvature of the first back portion 221a, 221b along the width direction is higher than the curvature of the second back portion 222 along the width direction.

[0053] According to the above structure, when a brush, a hand, etc. are slid laterally in the recess 200, the brush, the hand, etc. can be pulled out of the recess without resistance from either end on the left or right sides. Thus, the garbage in the recess 200 can be easily removed. Therefore, the top 140 of the front panel 100 can be cleaned more easily.

[0054] Furthermore, since the entire surface of the recessed portion 200 is a smooth curved surface, the appearance of the recessed portion 200 can be improved. Furthermore, the design of the refrigerator 1 when viewed from the front can be improved.

[0055] In addition, in the shape of the conventional handle, when the hand is slid horizontally in the recess, it collides with the wall at the end, and when the hand is pulled out of the recess, it feels uncomfortable. On the other hand, in the refrigerator 1 of this embodiment, the surface of the recess 200 provided on the upper surface 140 of the front panel 100 provided in the drawer 10 is a smooth curved surface as a whole. That is, there are almost no protruding parts or angular parts on the surface of the recess 200. Therefore, the user can naturally pull out the hand from the recess 200 without feeling uncomfortable.

[0056] The embodiments disclosed herein are to be considered as illustrative in all respects and not restrictive. The scope of the present disclosure is not indicated by the above description but by the claims, and is intended to include all changes within the meaning and scope equivalent to the claims. In addition, the configurations obtained by combining the configurations of the different embodiments described in this specification are also included in the scope of the present invention.
