[0010] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. The names and functions of the components are also the same. Therefore, detailed description thereof will not be repeated.

[0011] (Overall configuration of the refrigerator) First, the overall configuration of a refrigerator 1 according to this embodiment will be described. Fig. 1 shows the overall configuration of a refrigerator 1 according to this embodiment.

[0012] The refrigerator 1 includes an insulated box 50. The insulated box 50 has walls including a heat insulating material 51. A storage compartment 10 for storing food and the like is provided inside the insulated box 50. The storage compartment 10 is divided into multiple spaces by partitions 55. For example, the storage compartment 10 is made up of multiple spaces such as a refrigerator compartment, a freezer compartment, and a vegetable compartment.

[0013] A plurality of doors 11a, 11b, and 11c are provided on the front side of the heat-insulating box 50. The number of doors is not particularly limited.

[0014] In this embodiment, the surface on which the door is provided is defined as the front (front face) of the refrigerator. Based on the front face, the respective sides of the refrigerator 1 are defined as the top, side, back, and bottom faces, based on the positions where the refrigerator 1 would be when installed in a normal state. Therefore, in this specification, when the terms "front side" and "rear side" are defined, they refer to the side on which the front or back face is provided relative to an arbitrary position, or the direction from an arbitrary position toward the front or back face.

[0015] A cooling chamber 20 is provided on the rear side of the storage chamber 10. Inside the cooling chamber 20, there are arranged a cooler (also called an evaporator) 21 that constitutes a refrigeration cycle, a heater 22 for melting frost that has adhered to the cooler, a cooling fan (not shown) for sending air cooled by the cooler to the storage chamber 10, a drip tray (receptacle) 23 for receiving defrost water generated when the cooler 21 is defrosted, and the like.

[0016] A machine chamber 30 is provided below the rear side of the insulating box 50. A compressor (not shown), an evaporation tray 33, and the like are arranged inside the machine chamber 30. The evaporation tray 33 is arranged, for example, above the compressor. A drain pipe 32 is arranged above the evaporation tray 33. The drain pipe 32 is connected to an opening formed in the bottom surface 25 of the cooling chamber 20.

[0017] Drain pipe 32 is provided so as to penetrate heat insulating material 51 between cooling chamber 20 and machine chamber 30. Condensation water that melts during defrosting operation flows through drain pipe 32 from an opening provided on the bottom surface of cooling chamber 20 and is discharged into evaporator tray 33. Condensation water generated in cooling chamber 20 includes, for example, defrosted water generated when the cooler is defrosted. The condensation water discharged into evaporator tray 33 is warmed by the heat of the compressor and evaporates.

[0018] (Configuration of the bottom of the cooling chamber) Next, the configuration around bottom surface 25 of cooling compartment 20 will be described. Fig. 2 shows the components provided on the rear side of refrigerator 1. Fig. 2 shows the rear side of partition wall 26 provided between cooling compartment 20 and storage compartment 10. Cooling compartment 20 is located on the rear side of partition wall 26.

[0019] The lower part of the cooling chamber 20 is formed by a box-shaped bottom surface portion 25. A heater unit 40 including a heater 22 is disposed within the bottom surface portion 25. Although not shown in FIG. 2, a cooler 21 is disposed above the heater unit 40.

[0020] (Heater unit configuration) The following describes the detailed configuration of the heater unit 40. Figure 3 shows the appearance of the heater unit 40. Figure 4 shows the heater unit 40 with the heater cover 42 removed.

[0021] The heater unit 40 includes a heater 22, a drip tray (receiving tray) 23, and a heater cover .

[0022] In the following, when describing the shape and positional relationship of each component of heater unit 40, for convenience, heater unit 40 is defined by three coordinate axes: X (X1-X2) direction (left-right direction), Y (Y1-Y2) direction (up-down direction), and Z (Z1-Z2) direction (front-rear direction) as shown in Fig. 3 etc. These coordinate axes are defined based on the position of heater unit 40 when it is placed inside refrigerator 1.

[0023] The heater 22 has an elongated shape. The heater 22 is, for example, a glass tube heater. The heater 22 is disposed below the cooler 21 and extends in the left-right direction along the lower end of the cooler 21. The heater 22 is turned on during defrosting operation and melts frost adhering to the cooler 21.

[0024] Drip tray 23 is disposed below heater 22, i.e., at the bottom of cooling chamber 20. Fig. 5 shows the external appearance of drip tray 23 alone. Fig. 5 shows the state in which heater supports 41a and 41b provided on drip tray 23 are laid down (deployed).

[0025] The drip tray 23 is disposed between the bottom surface of the cooling chamber 20 and the heater 22. The drip tray 23 is formed of a metal plate with a relatively high thermal conductivity, such as iron or aluminum. During defrosting operation, the drip tray 23 receives heat from the heater 22 and transmits this heat to the surrounding area as radiant heat. The bottom surface of the cooling chamber 20 is formed of a resin bottom surface portion 25, while the drip tray 23 is formed of a metal with a higher thermal conductivity than resin. By providing such a drip tray 23, light and heat from the heater 22 do not directly hit the resin bottom surface portion 25, allowing frost, ice, etc. formed in the cooling chamber 20 to be safely heated.

[0026] The heater cover 42 is disposed above the heater 22 so as to cover the heater 22. Like the drip tray 23, the heater cover 42 is formed from a metal plate having a relatively high thermal conductivity, such as iron or aluminum.

[0027] Drip tray 23 is formed by molding a metal plate into a predetermined shape (see FIG. 5). Drip tray 23 has front surface 23a, bottom surface 23b, rear surface 23c, and heater supports 41a and 41b provided on both the left and right sides.

[0028] Front surface portion 23a forms the front wall of drip tray 23. Rear surface portion 23c forms the rear wall of drip tray 23. For example, front surface portion 23a is formed by bending a plate-shaped portion located on the front side of bottom surface portion 23b approximately vertically, and rear surface portion 23c is formed by bending a plate-shaped portion located on the rear side of bottom surface portion 23b approximately vertically. The height of rear surface portion 23c is greater than the height of front surface portion 23a.

[0029] The bottom surface portion 23b is provided so as to fit along the bottom surface of the cooling chamber 20. A drain hole 24 is formed in the bottom surface portion 23b at approximately the center in the left-right direction (X direction).

[0030] Heater supports 41a and 41b are disposed at both ends in the longitudinal direction (X direction shown in FIG. 3) of heater 22. As shown in FIG. 4, heater support 41a supports the left end (X1 side) of heater 22, and heater support 41b supports the right end (X2 side) of heater 22.

[0031] 5, heater support 41a is formed by bending a plate-shaped portion located on the left side (X1 side) of bottom surface portion 23b approximately vertically. Heater support 41b is formed by bending a plate-shaped portion located on the right side (X2 side) of bottom surface portion 23b approximately vertically. As described above, in this embodiment, heater supports 41a and 41b are provided on drip tray 23. That is, heater supports 41a and 41b are formed as components of drip tray 23.

[0032] However, in another embodiment, heater supports 41a and 41b may be formed of components separate from drip tray 23. For example, heater supports may be attached to bottom surface 25 of cooling chamber 20. In this case, too, heater supports are disposed at both ends of heater 22 in the longitudinal direction (X direction shown in FIG. 3) and support the heater.

[0033] Heater support 41a has a planar protrusion 43, a convex portion 44, a front planar protrusion 45, and a heater fitting hole 48. Similarly, heater support 41b has a planar protrusion 43, a convex portion (second protrusion) 44, a front planar protrusion (second protrusion) 45, and a heater fitting hole 48 into which heater 22 is fitted. Heater supports 41a and 41b have bilaterally symmetrical configurations.

[0034] Planar protrusion 43 is formed as part of a plate-like member that forms heater support 41a or 41b. Planar protrusion 43 is formed so as to protrude upward from the upper end of heater support 41a or 41b. Planar protrusion 43 is inserted into an insertion hole (specifically, top surface insertion hole 46) provided in heater cover 42. After being inserted into top surface insertion hole 46 of heater cover 42, planar protrusion 43 is bent outward (see FIG. 3).

[0035] The protrusion 44 is formed on the surface of the planar protrusion 43. The protrusion 44 protrudes in a direction intersecting the surface of the planar protrusion 43. The protrusion 44 is an example of a second protrusion that protrudes in a direction (specifically, the X direction) intersecting the insertion direction (specifically, the Y direction) of the planar protrusion 43 into the insertion hole. The protrusion 44 protrudes inside the heater unit 40 when the planar protrusion 43 is not bent and extends upward (the state shown in Figures 6 and 7). In other words, the protrusion 44 formed on the planar protrusion 43 of the heater support 41a protrudes to the right (X2 side).

[0036] By providing such a protrusion 44, it becomes possible to make it difficult for the heater cover 42 to come off the heater support when vibration is applied to the heater unit 40, for example.

[0037] When a strong external impact is applied to refrigerator 1, planar protrusion 43 that was bent while inserted into insertion hole 46 may stand up. In such a case, if vibration is applied to heater unit 40 in the vertical direction (Y direction), planar protrusion 43 that is inserted in the vertical direction (Y direction) relative to insertion hole 46 may come out of the hole.

[0038] Therefore, by providing a convex portion 44 that protrudes in a direction (specifically, the X direction) that intersects with the insertion direction (specifically, the Y direction) of the planar protrusion portion 43, it is possible to prevent the heater cover 42 from coming off when vibrations are applied to the heater unit 40 in the vertical direction (Y direction).

[0039] The front planar protrusion 45 is formed at a position different from the planar protrusion portion 43. The front planar protrusion 45 is formed as part of a plate-like member that forms the heater support 41a or 41b. The front planar protrusion 45 is formed so as to protrude forward from the front end of the heater support 41a or 41b.

[0040] The front planar protrusion 45 is inserted into an insertion hole (specifically, a front insertion hole 47) provided in the heater cover 42. After being inserted into the front insertion hole 47 of the heater cover 42, the front planar protrusion 45 is bent downward (see FIG. 3).

[0041] The front planar protrusion 45 is an example of a second protrusion extending in a direction (specifically, the X direction) intersecting the insertion direction (specifically, the Y direction) of the planar protrusion portion 43 into the insertion hole. In this embodiment, the front planar protrusion 45 has a surface (i.e., the XZ surface) extending in a direction intersecting the main body surface of the heater support 41a when extended forward (the state shown in FIGS. 6 and 7).

[0042] The provision of such a front planar protrusion 45 makes it difficult for the heater cover 42 to come off the heater support when vibrations are applied to the heater unit 40. More specifically, the provision of the front planar protrusion 45 extending in a direction intersecting the insertion direction of the planar protrusion portion 43 (specifically, the Y direction) makes it possible to prevent the heater cover 42 from coming off when vibrations are applied to the heater unit 40 in the up-down direction (Y direction).

[0043] Furthermore, when a force is applied to the heater unit 40 in the left-right direction (X direction), the heater support may tilt left-right, causing the planar protrusion 43 on one of the left and right sides to slip out of the hole. Therefore, in this embodiment, by providing a front planar protrusion 45 that extends left-right (X direction), the left-right positions of the heater cover 42 and the heater support can be fixed, preventing the heater support from tilting.

[0044] Therefore, it is possible to prevent the heater cover 42 from coming off when vibrations are applied in the up-down direction (Y direction) and the left-right direction (X direction).

[0045] In another embodiment, the front planar protrusion 45 may have a surface (i.e., a YZ plane) that extends in a direction parallel to the main body surface of the heater support 41a or 41b when it extends forward. Such a front planar protrusion 45 is an example of a second protrusion that extends in a direction (specifically, the Z direction) that intersects with the insertion direction (specifically, the Y direction) of the planar protrusion portion 43 into the insertion hole. Such a front planar protrusion 45 can fix the positions of the heater cover 42 and the heater support in the up-down direction, making it difficult for the heater cover 42 to come off the heater support.

[0046] In the present embodiment, the heater supports 41a and 41b have been described as having two types of second protrusions, namely, the protrusions 44 and the front planar protrusions 45. However, in another embodiment, the heater supports 41a and 41b may have only one of the protrusions 44 and the front planar protrusions 45. That is, it is sufficient for the heater support to have at least one type of second protrusion. Furthermore, the protrusions 44 may be formed on the front planar protrusions 45.

[0047] The heater cover 42 has an upper surface portion 42a and a front surface portion 42b formed by bending the front portion of the upper surface portion 42a. Upper surface insertion holes 46 are provided near both left and right ends of the upper surface portion 42a. Front surface insertion holes 47 are provided near both left and right ends of the front surface portion 42b.

[0048] The planar protrusions 43 of the heater supports 41a and 41b are inserted into the top surface insertion holes 46. The top surface insertion holes 46 have an elongated shape that is long in the front-to-back direction (Z direction) and narrow in the left-to-right direction (X direction) to match the shape of the planar protrusions 43.

[0049] The front planar protrusions 45 of the heater supports 41a and 41b are inserted into the front insertion holes 47. The front insertion holes 47 have an elongated shape that is long in the left-right direction (X direction) and narrow in the up-down direction (Y direction) to match the shape of the front planar protrusions 45.

[0050] Fig. 8 shows a state in which heater 22 is attached to drip tray 23. Fig. 9 shows a state in which heater cover 42 is placed over drip tray 23 in the state shown in Fig. 8.

[0051] When assembling the heater unit 40, the drip tray 23 is first formed. Specifically, with the drip tray 23 in the state shown in FIG. 5, the heater supports 41a and 41b on both the left and right sides are bent upward. This causes the heater supports 41a and 41b to stand upright, approximately perpendicular to the bottom surface portion 23b. At this time, the front planar protrusion 45 is also bent forward.

[0052] Next, as shown in FIG. 8, the heater 22 is fitted into each of the heater fitting holes 48 of the heater supports 41a and 41b.

[0053] 9, the heater cover 42 is attached to the heater supports 41a and 41b. Specifically, the planar protrusions 43 are inserted into the upper surface insertion holes 46, and the front planar protrusions 45 are inserted into the front surface insertion holes 47. This positions the heater cover 42 so as to cover the upper side of the heater 22.

[0054] Finally, as shown in FIG. 3, the planar projection 43 is bent outward, and the front planar projection 45 is bent downward.

[0055] As described above, the refrigerator 1 according to this embodiment includes the cooler 21, the heater 22 that melts frost adhering to the cooler 21, and the cooling compartment 20 in which the cooler 21 and the heater 22 are disposed. Holders (specifically, heater supports 41a and 41b) that hold the heater 22 are provided at both longitudinal ends of the heater 22. In this embodiment, the heater supports 41a and 41b are formed integrally with the drip tray 23. A heater cover 42 that is disposed to cover the heater 22 is provided above the heater 22.

[0056] The heater supports 41a and 41b have planar protrusions 43 that are inserted into insertion holes 46 provided in the heater cover 42. The provision of these planar protrusions 43 prevents the heater cover 42 from coming off when vibrations are applied in the left-right direction (X direction) or the front-back direction (Z direction). However, if only the planar protrusions 43 are used, there is a possibility that the heater cover 42 will come off when vibrations are applied in the up-down direction (Y direction).

[0057] Therefore, the heater supports 41a and 41b have second projections (specifically, convex portions 44 and front planar projections 45) that protrude or extend in a direction intersecting the insertion direction of the planar projections 43.

[0058] This makes it possible to restrict movement of heater cover 42 in a direction intersecting (orthogonal to) the surface of planar protrusion 43. In particular, if planar protrusion 43 that was bent has become erect due to the influence of vibration or impact, it is possible to prevent heater cover 42 from coming off when vibration is applied in the up-down direction (Y direction).

[0059] According to the above configuration, it is possible to form heater unit 40 in which heater supports 41a and 41b and heater cover 42 are not easily separated from each other. It is also possible to realize a configuration that can stably hold heater 22 even when refrigerator 1 receives an impact.

[0060] (Variation) In the above embodiment, the second protrusion is inserted into the insertion hole provided in the heater cover, but the second protrusion may be inserted into a component other than the heater cover. For example, the second protrusion may be inserted into the back surface portion 23c of the drip tray 23.

[0061] Drip tray 23 according to this modified example will be described with reference to Fig. 10. Rear surface portion 23c of drip tray 23 shown in Fig. 10 has rear surface insertion holes (second insertion holes) 147 provided near both the left and right ends. Second protrusions formed on heater supports 41a and 41b are inserted into rear surface insertion holes 147.

[0062] The second protrusions are provided at the rear end portions (positions indicated by A in FIG. 10) of the heater supports 41a and 41b of the drip tray 23. The second protrusions are, for example, rear planar protrusions having a shape that extends in a direction (specifically, the X direction) that intersects with the insertion direction (specifically, the Y direction) of the planar protrusion portion 43 into the insertion hole.

[0063] By providing such rear planar protrusions, heater supports 41a and 41b are less likely to fall outward when vibrations are applied to heater unit 40, thereby reducing the possibility of the heater cover coming off the heater support.

[0064] In addition, when such a rear planar projection is provided, the front planar projection 45 does not have to be provided.

[0065] (summary) A refrigerator (e.g., refrigerator 1) according to one aspect of the present invention includes a cooler (e.g., cooler 21), a heater (e.g., heater 22) that melts frost adhering to the cooler, a cooling chamber (e.g., cooling chamber 20) in which the cooler and the heater are disposed, holders (e.g., heater supports 41a and 41b) that are disposed at both longitudinal ends of the heater and hold the heater, and a heater cover (e.g., heater cover 42) that is disposed above the heater to cover the heater. The holder has a planar protrusion (e.g., planar protrusion 43) that is inserted into an insertion hole (e.g., upper surface insertion hole 46) provided in the heater cover, and the holder has a second protrusion (e.g., convex portion 44, front planar protrusion 45) that protrudes or extends in a direction (e.g., X direction or Z direction) intersecting the insertion direction (e.g., Y direction) of the planar protrusion.
