Summary of the Invention

Problems to be Solved by the Invention

[0005] r In the refrigerator disclosed in Patent Document 1, the compressor is directly attached to a stud portion formed by raising a constituent member of the recess. The compressor is placed on the stud portion via a cushioning material such as a rubber leg or a spring leg, and the cushioning material is fitted and attached to an attachment portion of the compressor.

[0006] However, the disclosure of Patent Document 1 does not disclose a structure for preventing the attachment portion of the compressor from coming off from the stud portion, and there is a risk that the compressor may float or come off due to vibrations during operation or the like.

[0007] Therefore, the objective of the present invention is to provide a refrigerator that can more reliably hold the compressor with respect to the bottom plate. [Means for solving the problem]

[0008] A refrigerator according to one aspect of the present invention comprises an insulated box, a machine room provided on the rear side of the insulated box, and a compressor located on the bottom plate of the machine room. The bottom plate has vertical plate portions that are erected by cutting notches into a part of the bottom plate, and a cushioning member, a part of the compressor located on the cushioning member, and a resin cap attached to the upper part of the vertical plate portion are attached to the vertical plate portion. [Effects of the Invention]

[0009] According to one aspect of the present invention, the compressor can be held more securely with respect to the bottom plate. [Brief explanation of the drawing]

Modes for Carrying Out the Invention

[0011] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions thereof will not be repeated.

[0012] <First Embodiment> (Overall Configuration of Refrigerator) First, the overall configuration of the refrigerator 1 according to the first embodiment will be described. FIG. 1 shows the front-side configuration of the refrigerator 1. FIG. 2 shows the back-side configuration of the refrigerator 1.

[0013] As shown in FIG. 1, the refrigerator 1 includes a freezer compartment in the upper stage and a refrigerator compartment in the lower stage. A freezer compartment door 11a is provided in the freezer compartment. A refrigerator compartment door 12a is provided in the refrigerator compartment.

[0014] As described above, the refrigerator 1 according to the present embodiment is divided into an upper stage portion and a lower stage portion, and each storage space is provided. However, the arrangement positions of the respective storage spaces are not limited thereto.

[0015] In this embodiment, the surface where the door is provided is referred to as the front or the front face of the refrigerator. And, based on the position where the refrigerator 1 is installed in its normal state with respect to the front face, each face of the refrigerator 1 is defined as the upper face, the side faces, the rear face, and the bottom face.

[0016] The refrigerator 1 is provided with a heat-insulating box body 50 as a heat-insulating structure for thermally insulating each storage space from the surroundings. A space for arranging the machine room 30 is formed on the lower rear side of the heat-insulating box body 50. In the machine room 30, a compressor 31 and the like that constitute a refrigeration cycle are arranged. The machine room 30 is located outside the heat-insulating box body 50. This is because the temperature in the machine room 30 rises when the compressor 31 is operated.

[0017] (Configuration inside the machine room) Subsequently, a more detailed configuration of the machine room 30 provided on the lower rear side of the heat-insulating box body 50 will be described. FIG. 3 shows the appearance of the compressor 31 arranged in the machine room 30. In FIG. 3, the compressor 31 installed on the bottom plate 20 is illustrated. In FIG. 3, illustration of components other than the compressor 31 in the machine room 30 is omitted. FIG. 4 shows a state where the compressor 31 shown in FIG. 3 is removed from the bottom plate 20.

[0018] In the machine room 30, for example, a compressor 31, a control unit 32, an evaporation tray 33, and the like are arranged. The bottom surface portion of the machine room 30 is constituted by a bottom plate 20 formed of a steel plate. In this embodiment, the compressor 31 is arranged slightly on the right side (left side when viewed from the front) inside the machine room 30 when viewed from the rear. However, the arrangement position of the compressor 31 in the machine room 30 is not limited to this.

[0019] The compressor 31 is fixed to the bottom plate 20. More specifically, a support plate 37 which is a part of the compressor 31 is connected to the bottom plate 20. The support plate 37 is a substantially horizontal plate-shaped metal member extending laterally from the main body portion of the compressor 31. In this embodiment, two support plates 37 extending laterally from the lower portions of the left and right side faces of the compressor 31 are provided respectively.

[0020] The compressor 31 is fixed to the bottom plate 20 by attaching a support plate 37 to a part of the bottom plate 20 (specifically, the vertical plate portion 21) along with various components (for example, a cushioning member 41, a resin cap 42, etc.). This fixed portion of the compressor 31 is called the support fixing portion 40. In this embodiment, two support fixing portions 40-40 are provided on one support plate 37 of the compressor 31, and two support fixing portions 40-40 are provided on the other support plate 37, for a total of four support fixing portions 40. However, the number of support fixing portions 40 is not limited to this.

[0021] (Configuration of the compressor's support and fixing section) Next, the detailed configuration of the support fixing part 40 will be described. Figures 4, 5, and 6 show the support fixing part 40 in a disassembled state, respectively. Figure 7 is a view from above of the support fixing part 40, 40 provided on one of the support plates 37 of the compressor 31.

[0022] Figures 8 and 9 show the internal structure of the support and fixing section 40. Figure 8 is a cross-sectional view of the section of the support and fixing section shown in Figure 7, along the line AA. Figure 9 is a cross-sectional view of the section of the support and fixing section shown in Figure 7, along the line BB.

[0023] The support and fixing section 40 is mainly composed of a part of the compressor 31 (specifically, the support plate 37), a part of the bottom plate 20 (specifically, the vertical plate section 21), a cushioning member 41, and a resin cap 42.

[0024] The support plate 37 is a roughly horizontal, plate-shaped metal member connected to the side of the compressor 31 and extending laterally from the main body of the compressor. The support plate 37 has an opening 37a at a position corresponding to the support fixing part 40 (see Figure 4). The vertical plate part 21 and the cushioning member 41 are placed in this opening 37a.

[0025] The vertical plate portion 21 is a plate-shaped member that extends approximately vertically upward from the upper surface of the base plate 20. The vertical plate portion 21 is formed by making a cut in a part of the base plate 20 and bending this cut portion to make it stand upright. In this vertical plate portion 21, the planar portion is called the planar portion 21a, and the left and right ends of the planar portion 21a are called the convex portions 21b (see Figure 8).

[0026] In this embodiment, a notch (recess) 21c is provided on one of the convex portions 21b of the vertical plate portion 21, which engages with the engaging projection 42d of the resin cap 42.

[0027] The cushioning member 41 is formed from a substantially cylindrical elastic member. Specific examples of elastic members include rubber and silicone resin. A through hole 41a is provided in the central part (axis portion) of the substantially cylindrical cushioning member 41. The vertical plate portion 21 is inserted into this through hole 41a, and the cushioning member 41 is positioned on the bottom plate 20 (see Figures 5 and 9, etc.). With such a cushioning member 41 provided, the cushioning member can absorb vibrations during the operation of the compressor 31. Therefore, the impact of the compressor 31's vibrations on the bottom plate 20 can be mitigated.

[0028] The cushioning member 41 has a main body portion 41b (also called a large-diameter portion 41b) and a small-diameter portion 41c located above the main body portion 41b and having a smaller diameter than the main body portion 41b. A groove 41d is provided between the main body portion 41b and the small-diameter portion 41c. A support plate 37 is fitted into the groove 41d (see Figures 6 and 9, etc.).

[0029] The resin cap 42 is made of a resin material that is harder than the cushioning member 41. Specific examples of resin materials include Delrin (POM), ABS, and HIPS. The resin cap 42 is attached to the upper part of the vertical plate portion 21. In this embodiment, the resin cap 42 is attached so as to cover the vertical plate portion 21 from above. By providing the resin cap 42 in this manner, which covers the upper part of the vertical plate portion 21, the compressor 31 can be held more securely against the bottom plate 20. This prevents the compressor 31 from floating or becoming detached due to vibrations during operation.

[0030] The resin cap 42 has a bottom portion 42a, a vertical plate housing portion 42b, a top portion 42c, an engaging projection 42d, and a bottom projection (movement restricting portion) 42e (see Figures 8 and 9).

[0031] The bottom portion 42a is positioned on the small-diameter portion 41c of the cushioning member 41. When the resin cap 42 is attached so as to cover the vertical plate portion 21, the bottom portion 42a is positioned approximately parallel to the support plate 37 of the compressor 31.

[0032] The vertical plate housing section 42b is a hook-shaped member that protrudes from the bottom surface section 42a and houses the upper portion of the vertical plate section 21 inside.

[0033] The upper surface portion 42c constitutes the upper part of the vertical plate housing portion 42b. In this embodiment, the upper surface portion 42c is configured to cover the top of the vertical plate portion 21. A narrow groove may be provided on the lower surface of the upper surface portion 42c (the side that houses the vertical plate) at a position that follows the shape of the vertical plate portion 21. This makes it possible to more reliably suppress misalignment between the vertical plate portion 21 and the resin cap 42 and cushioning member 41 attached to the vertical plate portion 21.

[0034] The engaging projection 42d is fitted into the notch 21c of the vertical plate portion 21 when the resin cap 42 is attached so as to cover the vertical plate portion 21 (see Figure 8). This makes the engagement between the vertical plate portion 21 and the resin cap 42 stronger, allowing the compressor 31 to be held more securely against the bottom plate 20.

[0035] The bottom projection 42e is a projection that protrudes downward from the center of the lower surface of the bottom portion 42a. With the resin cap 42 attached so as to cover the vertical plate portion 21, the bottom projection 42e fits into the through hole 41a of the cushioning member 41 (see Figure 9). In other words, the bottom projection 42e is positioned between the cushioning member 41 and the vertical plate portion 21. This allows the vertical plate portion 21 to be positioned at the center of the through hole 41a of the cushioning member 41. That is, the bottom projection 42e acts as a movement restricting part that restricts lateral displacement of the cushioning member 41, the support plate 37, and the compressor 31.

[0036] (modified version) In the configuration described above, a recess (specifically, a notch 21c) is provided on the vertical plate portion 21 that constitutes the support and fixing portion 40, and a projection (specifically, an engaging projection 42d) that fits into the recess is provided on the resin cap 42 (see Figure 8).

[0037] However, in the embodiment of the present invention, it is sufficient that a projection is provided on either the vertical plate portion 21 or the resin cap 42, and that the other vertical plate portion 21 or resin cap 42 is provided with a recess into which the projection engages.

[0038] In other words, as shown in the modified example in Figure 15, an engaging projection 321c may be provided on the vertical plate portion 321 side. In the example shown in Figure 15, the engaging projection 321c is provided on one of the convex portions 21b of the vertical plate portion 321. In this configuration, the vertical plate housing portion 42b of the resin cap 42 is provided with a recess into which the engaging projection 321c fits. This makes the engagement between the vertical plate portion 321 and the resin cap 42 stronger.

[0039] (Summary of the first embodiment) As described above, the refrigerator 1 according to this embodiment comprises an insulated box 50 and a machine room 30 provided on the lower rear side of the insulated box 50. A compressor 31 is arranged on the bottom plate 20 of the machine room 30. The bottom plate 20 has a vertical plate portion 21 that is erected by cutting a notch in a part of the bottom plate 20. A cushioning member 41, a part of the compressor (for example, a support plate 37) arranged on the cushioning member 41, and a resin cap 42 attached to the upper part of the vertical plate portion 21 are attached to the vertical plate portion 21. The vertical plate portion 21, the cushioning member 41, the support plate 37, and the resin cap 42 constitute a support fixing portion 40.

[0040] With the above configuration, the resin cap 42 that covers the upper part of the vertical plate 21 allows the compressor 31 to be held more securely against the bottom plate 20. This suppresses displacement of the compressor 31 due to vibrations during operation.

[0041] In the support and fixing part 40 described above, a projection (for example, an engaging projection 42d, an engaging projection 321c) is provided on either the vertical plate portion 21 (or vertical plate portion 321) or the resin cap 42, and a recess (for example, a notch 21c) is provided on the other of the vertical plate portion 21 (or vertical plate portion 321) or the resin cap 42 in which the projection engages. This allows for a stronger connection between the vertical plate portion 21 (or vertical plate portion 321) and the resin cap 42. Furthermore, when removing the resin cap 42 from the vertical plate portion 21, it can be easily removed by inserting a flat-head screwdriver or similar tool into the vertical plate housing portion 42b and opening the hook-shaped opening side (lower side).

[0042] Furthermore, the resin cap 42 is attached by placing it over the vertical plate portion 21 from above. This configuration makes it easier to attach and detach the resin cap 42 compared to conventional compressor fixing structures. Therefore, it is possible to improve the work efficiency during compressor installation.

[0043] <Second Embodiment> Next, a second embodiment of the present invention will be described. In the second embodiment, the configuration of the support and fixing part of the compressor differs from that of the first embodiment. For other configurations, the same configuration as in the first embodiment can be applied. Therefore, the second embodiment will be described focusing on the differences from the first embodiment.

[0044] Figure 10 shows the external configuration of the support and fixing portion 140 of the compressor 31 provided in the refrigerator 1 according to this embodiment. Figure 10 shows one of the support and fixing portions 140 provided on a single support plate 37. The other support and fixing portion 140 provided on the support plate 37 is not shown.

[0045] Figure 11 shows the configuration of the vertical plate portion 121 included in the support and fixing portion 140. Figure 12 shows the internal configuration of the support and fixing portion 140. Figure 12 is a diagram showing the cross-sectional configuration of the support and fixing portion 140 in the left-right direction.

[0046] The support and fixing section 140 mainly consists of a part of the compressor 31 (specifically, the support plate 37), a part of the bottom plate 20 (specifically, the vertical plate section 121), a cushioning member 41, and a resin cap 142. The same configuration as in the first embodiment can be applied to the support plate 37 and the cushioning member 41.

[0047] The vertical plate portion 121 is a plate-shaped member that extends almost vertically upward from the upper surface of the base plate 20. The vertical plate portion 121 is formed by making a cut in a part of the base plate 20 and bending this cut portion to make it stand upright. In this vertical plate portion 121, the planar portion is called the planar portion 121a, and the left and right ends of the planar portion 121a are called the convex portions 121b (see Figure 11).

[0048] In this embodiment, an engaging projection 121c is provided on one of the planar portions 121a of the vertical plate portion 121, which engages with the recess 142d of the resin cap 142. As shown in Figure 11, the engaging projection 121c is formed by making an incision in a part of the planar portion 121a and bending it so that it protrudes from the surface of the planar portion 121a.

[0049] The resin cap 142 is made of a resin material that is harder than the cushioning member 41, similar to the first embodiment. The resin cap 142 is attached to the upper part of the vertical plate portion 121. The resin cap 142 is attached so as to cover the vertical plate portion 121 from above. By providing the resin cap 142 so as to cover the upper part of the vertical plate portion 121, the compressor 31 can be held more securely against the bottom plate 20. This makes it possible to suppress displacement of the compressor 31 due to vibrations during operation.

[0050] The resin cap 142 has a bottom portion 42a, a vertical plate housing portion 142b, a top portion 142c, a recess 142d, and a bottom projection (movement restricting portion) 42e (see Figures 10 and 12). The bottom portion 42a and the bottom projection 42e have the same configuration as the resin cap 42 described in the first embodiment.

[0051] The vertical plate housing section 142b is a member that protrudes upward from the bottom surface section 42a and houses the upper portion of the vertical plate section 121 inside.

[0052] The upper surface portion 142c constitutes the upper part of the vertical plate housing portion 142b. In this embodiment, a narrow groove 142f is formed on the upper surface portion 142c at a position corresponding to the top of the vertical plate portion 121 (see Figure 12). As a result, when the resin cap 142 is attached to the vertical plate portion 121, the top of the vertical plate portion 121 fits into the groove 142f, making the connection between the resin cap 142 and the vertical plate portion 121 stronger.

[0053] The recess 142d is provided on one side of the vertical plate housing 142b (specifically, the side facing the planar portion 121a on the side where the engaging projection 121c of the vertical plate portion 121 is provided). In this embodiment, the recess 142d is formed by opening the wall portion of the vertical plate housing 142b. However, in another example, the recess 142d may be formed by recessing a part of the inner wall of the vertical plate housing 142b. With the resin cap 142 attached so as to cover the vertical plate portion 121, the engaging projection 121c of the vertical plate portion 121 fits into the recess 142d (see Figure 12). This makes the engagement between the vertical plate portion 121 and the resin cap 142 stronger, allowing the compressor 31 to be held more securely against the bottom plate 20.

[0054] As described above, in the configuration according to this embodiment, a projection (specifically, an engaging projection 121c) is provided on the vertical plate portion 121 side that constitutes the support fixing portion 140, and a recess (specifically, a recess 142d) is provided on the resin cap 142 side that engages with the projection.

[0055] Furthermore, in the configuration according to this embodiment, an engaging projection 121c is provided on the planar portion 121a of the vertical plate portion 121. In addition, in the configuration according to this embodiment, the engaging projection 121c of the vertical plate portion 121 communicates with the outside of the resin cap 142 via a groove 142f or recess 142d. As a result, when removing the resin cap 142 from the vertical plate portion 121, it can be easily removed by inserting a plate-shaped or rod-shaped jig or the like into the groove 142f or recess 142d and pressing down on the engaging projection 121c.

[0056] <Third Embodiment> Next, a third embodiment of the present invention will be described. In the third embodiment, the configuration of the support and fixing part of the compressor differs from that of the first embodiment. For other configurations, the same configuration as in the first embodiment can be applied. Therefore, the third embodiment will be described focusing on the differences from the first embodiment.

[0057] Figure 13 shows the internal structure of the support and fixing section 240 of the compressor 31 provided in the refrigerator 1 according to this embodiment. Figure 13 is a diagram showing the cross-sectional structure of the support and fixing section 240 in the left-right direction. Figure 14 shows the structure of the vertical plate section 221 included in the support and fixing section 240.

[0058] The support and fixing section 240 mainly consists of a part of the compressor 31 (specifically, the support plate 37), a part of the bottom plate 20 (specifically, the vertical plate section 221), a cushioning member 41, and a resin cap 242. The same configuration as in the first embodiment can be applied to the support plate 37 and the cushioning member 41.

[0059] The vertical plate portion 221 is a plate-shaped member that extends approximately vertically upward from the upper surface of the base plate 20. The vertical plate portion 221 is formed by making a cut in a part of the base plate 20 and bending this cut portion to make it stand upright. In this vertical plate portion 221, the planar portion is called the planar portion 221a, and the left and right ends of the planar portion 221a are called the convex portions 221b (see Figure 14).

[0060] In this embodiment, the planar portion 221a of the vertical plate portion 221 is provided with an opening 221c that engages with the engaging projection 242d of the resin cap 242. In another example, the opening 221c may be a recess formed by shaping a part of the planar portion 221a of the vertical plate portion 221.

[0061] The resin cap 242 is made of a resin material that is harder than the cushioning member 41, similar to the first embodiment. The resin cap 242 is attached to the upper part of the vertical plate portion 221. The resin cap 242 is attached so as to cover the vertical plate portion 221 from above. By providing the resin cap 242 that covers the upper part of the vertical plate portion 221 in this way, the compressor 31 can be positioned more firmly against the bottom plate 20. This makes it possible to reliably prevent the compressor 31 from shifting position due to vibrations during operation.

[0062] The resin cap 242 has a bottom portion 42a, a vertical plate housing portion 242b, an upper portion 242c, an engaging projection 242d, and a bottom projection (movement restricting portion) 42e (see Figure 13). The bottom portion 42a and the bottom projection 42e have the same configuration as the resin cap 42 described in the first embodiment.

[0063] The vertical plate housing section 242b is a member that protrudes upward from the bottom surface section 42a and houses the upper portion of the vertical plate section 221 inside.

[0064] The upper surface portion 242c constitutes the upper part of the vertical plate housing portion 242b. In this embodiment, a narrow groove 242f is formed on the upper surface portion 242c at a position corresponding to the top of the vertical plate portion 221 (see Figure 13). This allows the top of the vertical plate portion 221 to fit into the groove 242f when the resin cap 242 is attached to the vertical plate portion 221, thereby making the connection between the resin cap 242 and the vertical plate portion 221 stronger.

[0065] The engaging projection 242d is provided on the inner wall of one side of the vertical plate housing 242b. That is, the engaging projection 242d is provided so as to protrude toward the opening 221c formed in the planar portion 221a of the vertical plate portion 221 that is housed in the vertical plate housing 242b. When the resin cap 242 is attached so as to cover the vertical plate portion 221, the engaging projection 242d of the resin cap 242 fits into the opening 221c of the vertical plate portion 221 (see Figure 13). This makes the engagement between the vertical plate portion 221 and the resin cap 242 stronger, and allows the compressor 31 to be held more securely against the bottom plate 20.

[0066] As described above, in the configuration according to this embodiment, a recess (specifically, an opening 221c) is provided on the vertical plate portion 221 side that constitutes the support fixing portion 240, and a projection (specifically, an engaging projection 242d) that fits into the recess is provided on the resin cap 242 side.

[0067] Furthermore, in the configuration according to this embodiment, an opening is provided in the planar portion 221a of the vertical plate portion 221. Also, in the configuration according to this embodiment, the engaging projection 242d of the vertical plate portion 221 communicates with the outside of the resin cap 242 via the groove 242f or the opening 221c. As a result, when removing the resin cap 242 from the vertical plate portion 221, it can be easily removed by inserting a plate-shaped or rod-shaped jig into the groove 242f or the opening 221c and pushing in the engaging projection 242d.
