MODE FOR CARRYING OUT THE INVENTION

[0020] <Embodiment 1> Embodiment 1 will be described with reference to FIGS. 1 to 14. In this embodiment, the showcase 10 is exemplified as an example of a cooling storage device. In each drawing, the left direction is indicated by the arrow L, the right direction by the arrow R, the front direction by the arrow F, the rear direction by the arrow B, the upward direction by the arrow U, and the downward direction by the arrow D, and each part will be described accordingly.

[0021] The showcase (refrigerated storage, refrigerated showcase) 10 according to this embodiment stores and displays stored items (not shown) such as food products and beverages in a refrigerated state. As shown in Figure 1, the showcase 10 comprises a housing 10B which consists of a machine room 13, a storage room 19, and a cooler room 20. The housing 10B is fitted with a door 12 and a front panel (panel) 30, and houses a refrigeration device 14 inside. The refrigeration device 14 is a device that generates cold air and comprises a compressor 15, a condenser 16 (see Figure 2), and a cooler 17 (see Figure 2). Each component of the refrigeration device 14 is circulated and connected by a refrigerant pipe 18 (see Figure 2).

[0022] As shown in Figure 2, the insulated box 11 constitutes the main part of the housing 10B. The insulated box 11 is composed of an outer box 11A and an inner box 11B. The outer box 11A and inner box 11B are made of metal plates such as stainless steel plates that have been processed into a predetermined shape. An insulating material (not shown) made of foamed resin is foamed and filled between the outer box 11A and the inner box 11B. In addition to constituting the storage room 19 and the cooler room 20, the insulated box 11 also constitutes a part of the machine room 13. Specifically, the insulated box 11 has a vertically elongated, roughly box-shaped main body 11C that opens to the front, and an extension 11D that extends downward from the main body 11C. The main body 11C constitutes the storage room 19 and the cooler room 20. A pair of extensions 11D are provided at both ends of the main body 11C in the left-right direction. The pair of extensions 11D are arranged opposite each other with a gap between them in the left-right direction, and constitute a part of the machine room 13.

[0023] As shown in Figure 2, the storage compartment 19 occupies most of the space within the main body 11C, and stored items can be loaded and unloaded through a front opening in the main body 11C. Inside the storage compartment 19, there are multiple shelves 21 on which stored items are placed. A sliding door 12 is attached to the opening of the storage compartment 19. Rails 22 are provided above and below the opening of the storage compartment 19 to support the door 12 so that it can slide along the left and right directions, and side frames 23 (see Figure 1) are provided on both the left and right sides. Two doors 12 are attached to the opening of the storage compartment 19 at positions offset front to back.

[0024] As shown in Figure 2, the cooler chamber 20 is located near the upper end of the space within the main body 11C and is separated from the storage chamber 19 by an air duct 24. In addition to the cooler 17 that constitutes the refrigeration system 14, the cooler chamber 20 also houses a circulation fan 17A. The cold air generated by the cooler 17 is circulated into the storage chamber 19 by the circulation fan 17A. As a result, the stored items in the storage chamber 19 are cooled.

[0025] As shown in Figure 2, the machine room 13 is located below the storage room 19 and is separated from the storage room 19 by the bottom 11C1 of the main body 11C that constitutes the insulated box 11. A base portion 25, which constitutes part of the housing 10B, is attached to the extended ends of a pair of extensions 11D that constitute the insulated box 11. The base portion 25 is roughly plate-shaped and is positioned opposite the bottom 11C1 of the main body 11C with a gap in the vertical direction. A rear panel 26, which constitutes part of the housing 10B, is attached to the rear ends of the main body 11C and the base portion 25 that constitute the insulated box 11. The rear panel 26 is roughly plate-shaped and is positioned to close off the space enclosed by the bottom 11C1 of the main body 11C, the pair of extensions 11D, and the base portion 25 from the rear. The space enclosed by the bottom 11C1 of the main body 11C, the pair of extensions 11D, the base 25, and the rear panel 26 is a machine room 13 that opens only to the front.

[0026] As shown in Figure 2, the machine room 13, configured in this way, houses the compressor 15 and condenser 16 that constitute the refrigeration system 14. The compressor 15 and condenser 16 are mounted on a slide plate 27 that is attached to the base 25 in a manner that allows them to slide along the front-rear direction. The slide plate 27 is roughly plate-shaped and parallel to the main surface of the base 25, and can be moved in and out of the machine room 13 through an opening 13A located at the front of the machine room 13. A pair of rail sections 28 are attached to the base 25 to support the left and right side edges of the slide plate 27. The pair of rail sections 28 extend along the front-rear direction and have portions that face each other with a gap between them and the upper surface of the base 25, and by supporting the side edges of the slide plate 27 with these portions, the sliding movement of the slide plate 27 can be guided. The compressor 15 and condenser 16 housed in the machine room 13 are connected to the cooler 17 housed in the cooler room 20 via refrigerant pipes 18. The refrigerant pipe 18 is routed through a piping system provided in the insulated box 11, from the machine room 13 located below the storage room 19 to the cooler room 20 located above the storage room 19. The piping system of the refrigerant pipe 18 penetrates at least the bottom 11C1 of the main body 11C vertically.

[0027] As described above, the housing 10B of the showcase 10 according to this embodiment includes an insulated box 11, a base 25, and a rear panel 26, as shown in Figure 2. The insulated box 11 and the base 25 included in the housing 10B have a surrounding wall 29 that encloses the opening 13A of the machine room 13, as shown in Figure 3. The surrounding wall 29 is horizontally elongated and rectangular when viewed from the front, and is composed of the following four sides 29A to 29C. The opening 13A enclosed by such a surrounding wall 29 is horizontally elongated and rectangular when viewed from the front. The four sides 29A to 29C that make up the enclosure wall 29 include a pair of side sides (first side) 29A that extend vertically and are spaced apart horizontally, an upper side (second side) 29B that extends horizontally and intersects with the vertical direction, and a lower side (third side) 29C that extends horizontally and is spaced below the upper side 29B. The side sides 29A of the enclosure wall 29 are made up of the extensions 11D of the insulated box body 11. The upper side 29B of the enclosure wall 29 is made up of the bottom 11C1 of the main body 11C of the insulated box body 11. The lower side 29C of the enclosure wall 29 is made up of the base 25. The lower side 29C is positioned further back (towards the back of the machine room 13) than the side sides 29A and the upper side 29B.

[0028] As shown in Figure 3, a front panel (panel) 30 is attached to the enclosure wall 29 with this configuration so as to close the opening 13A. Below, the structure of the front panel 30 itself, along with the structure of how the front panel 30 is attached to the enclosure wall 29, will be described in detail. The front panel 30 is made, for example, by processing a metal plate into a predetermined shape. The front panel 30, like the opening 13A, has a panel body 30A that is horizontally elongated and rectangular when viewed from the front. The panel body 30A is a flat plate that is slightly smaller than the opening 13A, and when attached to the enclosure wall 29, it is surrounded by the enclosure wall 29 (see Figure 2). By making the panel body 30A slightly smaller than the opening 13A, it is made easier to insert and remove the panel body 30A into and out of the opening 13A. The panel body 30A has openings punched out on both the left and right sides, and a louver 31 is attached to the left opening, and a window frame 32 is attached to the right opening. The louvers 31 are made of synthetic resin and consist of multiple horizontally elongated vents 31A arranged vertically. Ventilation of the machine room 13 is provided through the vents 31A. As shown in Figure 4, an air filter 33 facing the vents 31A is removable from the louvers 31. The window frame 32 is made of synthetic resin and, as shown in Figure 3, has a frame shape that conforms to the opening on the right side. A window panel 34 capable of displaying the internal temperature and other information is attached to the window frame 32.

[0029] As shown in Figures 3 and 5, the front panel 30 has a first flange 30B, a second flange 30C, a side portion 30D, and an elastic contact piece 30E connected to the outer edge of the panel body 30A. The first flange 30B is provided so as to extend from the upper edge, which is the outer edge of the panel body 30A, toward the rear (towards the back of the machine room 13) in the front-rear direction. The first flange 30B extends in the left-right direction and is provided so as to extend along almost its entire length to the upper edge of the panel body 30A. When the front panel 30 is attached to the enclosure wall 29, as shown in Figure 4, the first flange 30B is positioned to face downwards (inwards) to the upper edge portion 29B of the enclosure wall 29.

[0030] As shown in Figures 3 and 5, the second flange 30C is provided in a manner that extends rearward along the front-rear direction from the lower edge, which is the outer edge of the panel body 30A. The second flange 30C extends along the left-right direction and is provided so as to be continuous with the lower edge of the panel body 30A for almost its entire length. The second flange 30C is positioned below the first flange 30B, facing it with a gap of approximately the vertical length of the panel body 30A. When the front panel 30 is attached to the enclosure wall 29, the second flange 30C is positioned in front of the lower edge 29C of the enclosure wall 29, as shown in Figure 4.

[0031] As shown in Figures 3 and 5, the piece 30D extends downward (outward) from the extended end (rear end) of the second flange 30C in parallel with the panel body 30A. The piece 30D extends along the left-right direction and is provided to connect with the extended end of the second flange 30C over most of its length (excluding the left end when viewed from the rear). When the front panel 30 is attached to the enclosure wall 29, the piece 30D is positioned to face the front side of the lower edge 29C of the enclosure wall 29, as shown in Figure 4. The piece 30D is provided with a screw insertion hole 30D1 through which a fixing screw (fixing means) B is passed. The lower edge 29C of the enclosure wall 29 is provided with a screw fastening hole 29C1 through which the fixing screw B is fastened, as shown in Figure 7. When the front panel 30 is attached to the enclosure wall 29, the screw insertion hole 30D1 of the side portion 30D communicates with the screw fastening hole 29C1 of the lower edge portion 29C, so that the fixing screw B is fastened to the screw fastening hole 29C1 through the screw insertion hole 30D1. This allows the front panel 30 to be fixed to the base portion 25 in an attached state. As described above, since the side portion 30D is provided at the extended end of the second flange 30C that extends from the outer edge of the panel body 30A toward the back of the machine room 13, the second flange 30C and the side portion 30D are positioned recessed further into the machine room 13 than the panel body 30A. As a result, the fixing point between the side portion 30D and the lower edge portion 29C is not easily visible from the outside, resulting in a superior appearance.

[0032] As shown in Figures 3 and 5, the elastic contact piece 30E is provided extending backward along the front-rear direction from the side edge, which is the outer edge of the panel body 30A. The elastic contact piece 30E extends along the vertical direction and is provided so as to be continuous with the side edge of the panel body 30A for almost its entire length. When the front panel 30 is attached to the enclosure wall 29, as shown in Figure 8, the elastic contact piece 30E faces inward against the side edge 29A of the enclosure wall 29 and is in elastic contact with the side edge 29A. This elastic contact piece 30E extends along the length direction (vertical direction) of the side edge 29A that constitutes the enclosure wall 29. Therefore, any gaps that may occur between the enclosure wall 29 and the front panel 30 are sealed over a wide area by the elastic contact piece 30E. In particular, in this embodiment, since the elastic contact piece 30E extends along the entire length of the side portion 29A, any gaps that may occur between the enclosure wall 29 and the front panel 30 are sealed along the entire length of the side portion 29A by the elastic contact piece 30E. Furthermore, since the elastic contact piece 30E makes elastic contact with the side portion 29A, it is possible to maintain a good state in which any gaps that may occur between the enclosure wall 29 and the front panel 30 are sealed. As a result, it becomes difficult for external water or outside air (including steam) to enter the machine room 13 through the gap between the enclosure wall 29 and the front panel 30. Consequently, the machinery such as the compressor 15 and condenser 16 located in the machine room 13 are less likely to malfunction, thus extending the product life of the showcase 10.

[0033] In this embodiment, the elastic contact piece 30E is provided on the front panel 30, as shown in Figure 3. Therefore, when the front panel 30 is removed from the surrounding wall 29, the elastic contact piece 30E is not present in the opening 13A surrounded by the surrounding wall 29, as shown in Figure 3. Consequently, interference with the elastic contact piece 30E can be avoided when performing maintenance or other work inside the machine room 13 through the opening 13A. This improves work efficiency and makes it less likely for unintended deformation to occur in the elastic contact piece 30E.

[0034] In this embodiment, the elastic contact piece 30E is provided to extend from the outer edge of the panel body 30A toward the back of the machine room 13, as shown in Figures 3, 5, and 8. In this configuration, when the front panel 30 is attached to the enclosure wall 29, the elastic contact piece 30E is positioned further back in the machine room 13 than the panel body 30A. As a result, the elastic contact piece 30E is less visible from the outside, resulting in a superior appearance.

[0035] In this embodiment, as shown in Figures 3, 5, and 8, a pair of elastic contact pieces 30E are provided so as to be spaced apart and facing each other in the longitudinal direction (left-right direction) of the upper edge portion 29B, which intersects with the side edge portion 29A of the enclosure wall 29. When the front panel 30 is attached to the enclosure wall 29, the pair of elastic contact pieces 30E are elastically contacted with the pair of side edge portions 29A that constitute the enclosure wall 29. The elastic force generated by the elastic deformation (bending deformation) of the pair of elastic contact pieces 30E centers the front panel 30 so that it is located in the center of the enclosure wall 29 in the left-right direction. As a result, the front panel 30 is less likely to be biased to either the left or right, resulting in a superior appearance.

[0036] In this embodiment, as shown in Figure 8, the elastic contact piece 30E is cantilevered with the side edge of the panel body 30A as its base end. More specifically, the elastic contact piece 30E has a first component 30E1 connected to the side edge of the panel body 30A and a second component 30E2 connected to the extended end of the first component 30E1. The first component 30E1 extends from the side edge of the panel body 30A toward the back of the machine room 13 and approaches the enclosure wall 29. Although there is a gap between the base end of the first component 30E1 and the side edge 29A of the enclosure wall 29, there is no gap between the extended end of the first component 30E1 and the side edge 29A of the enclosure wall 29, and the two are in contact. The second component 30E2 extends from the extended end of the first component 30E1 toward the back of the machine room 13 and away from the enclosure wall 29. There is no gap between the base end of the second component 30E2 and the side edge 29A of the enclosure wall 29, and the two are in contact, however there is a gap between the extended end of the second component 30E2 and the side edge 29A of the enclosure wall 29. The extended end of the second component 30E2 is positioned further from the side edge 29A of the enclosure wall 29 than the base end of the first component 30E1. In this way, the elastic contact piece 30E is shaped like a "V" when viewed in plan, and the point where the extended end of the first component 30E1 and the base end of the second component 30E2 connect constitutes the top portion 30E3. The top portion 30E3 is the part of the elastic contact piece 30E that is closest to the side edge portion 29A of the surrounding wall 29.

[0037] Before the front panel 30 is attached to the enclosure wall 29, as shown in Figure 13, the top portion 30E3 of the elastic contact piece 30E is located outward from the inner surface of the side edge portion 29A of the enclosure wall 29 (away from the center position in the left-right direction of the front panel 30). Therefore, when the front panel 30 is attached to the enclosure wall 29, as shown in Figure 8, the top portion 30E3 of the elastic contact piece 30E is displaced inward (towards the center position in the left-right direction of the front panel 30) by the inner surface of the side edge portion 29A of the enclosure wall 29. Consequently, the elastic contact piece 30E is elastically deformed with the base end of the first component 30E1 as a fulcrum, and the extended end of the second component 30E2 is displaced inward. Here, the force required to elastically deform the elastic contact piece 30E and the holding force of the front panel 30 when attached to the enclosure wall 29 change according to the distance from the base end to the top end 30E3 of the first component 30E1, i.e., the extension length. Specifically, the smaller the extension length of the first component 30E1, the greater the holding force of the front panel 30, but the greater the force required to elastically deform the elastic contact piece 30E, which worsens the ease of attaching and detaching (workability) of the front panel 30. Conversely, the larger the extension length of the first component 30E1, the smaller the force required to elastically deform the elastic contact piece 30E, which improves the ease of attaching and detaching the front panel 30, but the greater the holding force of the front panel 30. Therefore, by adjusting the extension length of the first component 30E1, a good balance can be maintained between the ease of attaching and detaching the front panel 30 to and from the enclosure wall 29, and the holding force of the front panel 30 when it is attached to the enclosure wall 29.

[0038] In this embodiment, as shown in Figures 6 and 13, the first flange 30B and the second flange 30C are configured such that their ends in the left-right direction are positioned at a distance from the elastic contact piece 30E. Specifically, both the first flange 30B and the second flange 30C are configured such that their dimensions in the left-right direction gradually decrease as they approach the extended end from the base end connected to the panel body 30A. Accordingly, both side edges (ends) of the first flange 30B and the second flange 30C in the left-right direction are inclined with respect to the front-rear and left-right directions. In the state before the front panel 30 is attached to the enclosure wall 29, that is, when the elastic contact piece 30E is in its natural state, a predetermined distance is maintained in the left-right direction between the side edges of the first flange 30B and the second flange 30C in the left-right direction and the extended end of the second component 30E2 that constitutes the elastic contact piece 30E. This spacing allows the elastic contact piece 30E to deform elastically without mechanically interfering with the first flange 30B and the second flange 30C. In other words, the space created between the left and right edges of the first flange 30B and the second flange 30C and the extended end of the second component 30E2 that constitutes the elastic contact piece 30E allows the deforming elastic contact piece 30E to escape. This ensures smooth elastic deformation and elastic recovery of the elastic contact piece 30E.

[0039] In this embodiment, as shown in Figures 3, 9, and 10, screws (positioning portion, retaining portion) 35 are attached to the side portions 29A that constitute the enclosure wall 29, which are capable of positioning and preventing the front panel 30 from coming loose. A pair of screws 35 are provided and are attached to each of the pair of side portions 29A that constitute the enclosure wall 29. The screws 35 are located near the upper end of the side portion 29A (closer to the upper portion 29B than to the lower portion 29C). The screws 35 have a shaft portion (projection) 35A that protrudes from the side portion 29A toward the elastic contact piece 30E, and a head portion (opposing portion) 35B that is connected to the protruding tip of the shaft portion 35A. The axis of the shaft portion 35A coincides with the left-right direction. The diameter of the head portion 35B is larger than the diameter of the shaft portion 35A. Therefore, the head portion 35B faces the side portion 29A that constitutes the surrounding wall 29, with a gap in the left-right direction equal to the protruding dimension of the shaft portion 35A.

[0040] In contrast, the elastic contact piece 30E is provided with a shaft insertion groove (projection insertion groove) 30E4 through which the shaft portion 35A of the screw 35 passes, as shown in Figures 3, 5, and 9. The shaft insertion groove 30E4 is roughly L-shaped when viewed from the side and consists of a first groove component 30E4A that opens in the front-rear direction toward the back of the machine room 13, and a second groove component 30E4B that is connected to the first groove component 30E4A and extends in the vertical direction. The first groove component 30E4A is provided in the elastic contact piece 30E over the entire length of the second component 30E2 in the front-rear direction, and extends to the extended end (top portion 30E3) of the first component 30E1. The second groove component 30E4B extends downward from the front end of the first groove component 30E4A and is provided by cutting out the top portion 30E3 of the elastic contact piece 30E. When the front panel 30 is attached to the enclosure wall 29, as shown in Figure 9, the shaft portion 35A of the screw 35 is positioned at the lower end of the second groove component 30E4B. In this state, the U-shaped portion of the groove edge of the shaft insertion groove 30E4 in the elastic contact piece 30E that surrounds the lower end of the second groove component 30E4B is locked to the shaft portion 35A of the screw 35. The portion of the groove edge of the shaft insertion groove 30E4 in the elastic contact piece 30E that is locked to the shaft portion 35A is designated as the locking portion 30E5. In this way, when attaching the front panel 30 to the enclosure wall 29, the shaft portion 35A of the screw 35 is passed from the first groove component 30E4A to the second groove component 30E4B in the shaft insertion groove 30E4 of the elastic contact piece 30E. When the front panel 30 is attached to the enclosure wall 29, the shaft portion 35A is locked into the locking portion 30E5, which is formed by the groove edge of the shaft insertion groove 30E4 in the elastic contact piece 30E. This positions the front panel 30 relative to the enclosure wall 29 in the front-rear direction (particularly preventing it from coming off forward) and also positions it upward, thus ensuring its retention.

[0041] When the front panel 30 is attached to the enclosure wall 29, as shown in Figure 10, the groove edge of the shaft insertion groove 30E4 in the elastic contact piece 30E is sandwiched in the left-right direction between the side portion 29A constituting the enclosure wall 29 and the head 35B of the screw 35. Therefore, when attaching the front panel 30 to the enclosure wall 29, the elastic contact piece 30E can be positioned between the side portion 29A and the head 35B of the enclosure wall 29 to guide the attachment process.

[0042] Furthermore, in this embodiment, as shown in Figures 2 and 3, the main body portion 11C of the insulated box 11 constitutes the cooler chamber 20 and the storage chamber 19, and the extension portion 11D of the insulated box 11 constitutes the side portion 29A of the enclosure wall 29. In this way, since the insulated box 11 constitutes a part of the machine room 13 (the side portion 29A of the enclosure wall 29), the number of components constituting the machine room 13 can be reduced.

[0043] This embodiment has the structure described above, and next, the installation of the front panel 30 will be explained. First, when the front panel 30 is removed from the enclosure wall 29, as shown in Figure 3, the machine room 13 is exposed to the outside through the opening 13A, so it is possible to perform maintenance and repair work on equipment such as the compressor 15 and condenser 16 located inside the machine room 13 through the opening 13A, or to pull out the slide plate 27 on which the compressor 15 and condenser 16 are mounted outside the machine room 13 through the opening 13A. When attaching the front panel 30 to the enclosure wall 29, as shown in Figure 11, first, the front panel 30 is positioned slightly lower than its position when attached to the enclosure wall 29 (see Figure 9), and the first groove component 30E4A of the shaft insertion groove 30E4 is aligned vertically with the shaft portion 35A of the screw 35.

[0044] In this state, when at least the upper portion of the front panel 30 (including the shaft insertion groove 30E4) is inserted into the opening 13A of the machine room 13, the shaft portion 35A of the screw 35 enters the first groove component 30E4A of the shaft insertion groove 30E4. At this time, as shown in Figure 12, the elastic contact piece 30E is guided in the left-right direction by being placed in the space between the side portion 29A constituting the enclosure wall 29 and the head portion 35B of the screw 35. During this process, as shown in Figure 13, the top portion 30E3 of the elastic contact piece 30E contacts the inner surface of the side portion 29A of the enclosure wall 29, causing the top portion 30E3 to displace inward while the first component 30E1 elastically deforms with its base end as the pivot point.

[0045] As shown in Figure 11, when the shaft portion 35A, which has entered the first groove component 30E4A, reaches the front end position of the first groove component 30E4A, the front panel 30 is displaced upward. Then, the shaft portion 35A enters the second groove component 30E4B from the first groove component 30E4A. When the shaft portion 35A reaches the lower end position of the second groove component 30E4B, as shown in Figures 9 and 10, the shaft portion 35A is locked into the locking portion 30E5 surrounding the lower end of the second groove component 30E4B. In this state, as shown in Figures 7 and 14, the screw insertion hole 30D1 provided in one side 30D of the second flange 30C communicates (aligns) with the screw fastening hole 29C1 provided in the lower side 29C of the surrounding wall 29, so that the fixing screw B can be passed through the screw insertion hole 30D1 and fastened into the screw fastening hole 29C1. The lower part of the front panel 30 is fixed to the surrounding wall 29 by fixing screws B. The upper part of the front panel 30 is fixed to the surrounding wall 29 by the locking of the shaft portion 35A with the locking portion 30E5, as shown in Figures 9 and 10.

[0046] As shown in Figure 8, a gap may be created between the panel body 30A of the front panel 30 and the surrounding wall 29 in order to ensure the ease of attaching and detaching the front panel 30. In contrast, the elastic contact piece 30E extends along the length of the side edge 29A that constitutes the surrounding wall 29 and is in elastic contact with the side edge 29A over almost its entire length. Therefore, the elastic contact piece 30E can seal the gap that may occur between the surrounding wall 29 and the panel body 30A over the entire length of the side edge 29A. This makes it difficult for external water, outside air, etc. to enter the machine room 13 through the gap between the surrounding wall 29 and the panel body 30A. As a result, the machinery such as the compressor 15 and condenser 16 located in the machine room 13 are less likely to malfunction, thus extending the product life of the showcase 10.

[0047] As described above, the mounting structure of the front panel (panel) 30 in this embodiment comprises a housing 10B constituting the machine room 13, having a surrounding wall 29 that surrounds an opening 13A that opens the machine room 13 to the outside, a front panel 30 attached to the surrounding wall 29 so as to close the opening 13A, and an elastic contact piece 30E provided on one of the surrounding wall 29 and the front panel 30 and elastically contacting the other of the surrounding wall 29 and the front panel 30, wherein the surrounding wall 29 is composed of a plurality of edges 29A to 29C, and the elastic contact piece 30E extends along the longitudinal direction of the side edges (first edges) 29A included in the plurality of edges 29A to 29C.

[0048] When the front panel 30 is removed from the enclosure wall 29, the machine room 13 is exposed to the outside through the opening 13A, making it possible to perform maintenance and other work inside the machine room 13 through the opening 13A. When the front panel 30 is installed to cover the enclosure wall 29, an elastic contact piece 30E provided on one of the enclosure wall 29 and the front panel 30 makes elastic contact with the other of the enclosure wall 29 and the front panel 30. Since this elastic contact piece 30E extends along the length of the side edge 29A included in the multiple edges 29A to 29C that make up the enclosure wall 29, any gaps that may occur between the enclosure wall 29 and the front panel 30 are sealed over a wide area by the elastic contact piece 30E. As a result, it becomes difficult for external water or other substances to enter the machine room 13 through the gap between the enclosure wall 29 and the front panel 30.

[0049] Furthermore, the elastic contact piece 30E is provided on the front panel 30 and makes elastic contact with the enclosure wall 29. When the front panel 30 is installed to close the enclosure wall 29, the elastic contact piece 30E provided on the front panel 30 makes elastic contact with the side edge 29A of the enclosure wall 29. When the front panel 30 is removed from the enclosure wall 29, the elastic contact piece 30E is not present in the opening 13A enclosed by the enclosure wall 29. Therefore, when performing maintenance or other work inside the machine room 13 through the opening 13A, interference with the elastic contact piece 30E can be avoided. This improves work efficiency and makes it less likely for unintended deformation to occur in the elastic contact piece 30E.

[0050] Furthermore, the front panel 30 has a panel body 30A surrounded by a wall 29, and the elastic contact piece 30E extends from the outer edge of the panel body 30A toward the back of the machine room 13. When the front panel 30 is attached to the wall 29, the panel body 30A is surrounded by the wall 29 and the elastic contact piece 30E is elastically in contact with the side edge 29A of the wall 29. Since the elastic contact piece 30E extends from the outer edge of the panel body 30A toward the back of the machine room 13, it is positioned recessed further into the machine room 13 than the panel body 30A. As a result, the elastic contact piece 30E is less visible from the outside, resulting in a superior appearance.

[0051] Furthermore, the elastic contact piece 30E has a first component 30E1 that extends from the outer edge of the panel body 30A toward the enclosure wall 29, and a second component 30E2 that extends from the extended end of the first component 30E1 toward the enclosure wall 29. The point where the extended end of the first component 30E1 and the base end of the second component 30E2 connect constitutes the top portion 30E3 of the elastic contact piece 30E that is closest to the side edge 29A of the enclosure wall 29. The elastic contact piece 30E elastically deforms with the base end of the first component 30E1 as a fulcrum when this top portion 30E3 contacts the side edge 29A of the enclosure wall 29. The force required to elastically deform the elastic contact piece 30E and the holding force of the front panel 30 when attached to the enclosure wall 29 vary depending on the distance from the base end of the first component 30E1 toward the top portion 30E3. Therefore, by adjusting the length of the first component 30E1, a good balance can be maintained between the ease of attaching and detaching the front panel 30 to and from the enclosure wall 29, and the holding force of the front panel 30 when it is attached to the enclosure wall 29.

[0052] Furthermore, the front panel 30 has a first flange 30B that extends from the outer edge of the panel body 30A toward the back of the machine room 13 and extends along the length of the upper edge (second edge) 29B, which is included in the multiple edges 29A to 29C and intersects with the side edge 29A. The first flange 30B is positioned opposite the upper edge 29B, and the end of the upper edge 29B in the length direction is positioned at a distance from the elastic contact piece 30E. When the front panel 30 is attached to the enclosure wall 29, the first flange 30B is positioned opposite the upper edge 29B of the enclosure wall 29. When attaching the front panel 30 to the enclosure wall 29, the positioning of the front panel 30 relative to the enclosure wall 29 in the length direction of the side edge 29A is achieved by the first flange 30B. The first flange 30B extends along the length of the upper edge 29B, which intersects with the side edge 29A, and a gap is left between its end and the elastic contact piece 30E. The space left between the end of the first flange 30B and the elastic contact piece 30E allows the deforming elastic contact piece 30E to move freely. This ensures smooth elastic deformation and elastic recovery of the elastic contact piece 30E.

[0053] Furthermore, the front panel 30 has a second flange 30C that extends from the outer edge of the panel body 30A toward the back of the machine room 13 and is included in the multiple sides 29A to 29C and intersects with the side side 29A, and a side piece 30D that extends outward from the extended end of the second flange 30C in a manner parallel to the panel body 30A, and the side piece 30D is fixed in contact with the lower side 29C. When the front panel 30 is attached to the enclosure wall 29, the side piece 30D comes into contact with the lower side 29C of the enclosure wall 29, and the side piece 30D can be fixed to the lower side 29C. Since the second flange 30C extends from the outer edge of the panel body 30A toward the back of the machine room 13, the second flange 30C and the side portion 30D are positioned recessed further into the machine room 13 than the panel body 30A. As a result, the fixing point between the side portion 30D and the lower edge portion 29C is less visible from the outside, resulting in a superior appearance.

[0054] Furthermore, the side edge 29A of the enclosure wall 29 is provided with a shaft portion (projection) 35A that protrudes toward the elastic contact piece 30E, and the elastic contact piece 30E is provided with a shaft portion insertion groove (projection insertion groove) 30E4 through which the shaft portion 35A passes, and a locking portion 30E5 formed by the groove edge of the shaft portion insertion groove 30E4, which locks the shaft portion 35A. When attaching the front panel 30 to the enclosure wall 29, the shaft portion 35A protruding from the side edge 29A of the enclosure wall 29 is passed through the shaft portion insertion groove 30E4 of the elastic contact piece 30E. When the front panel 30 is attached to the enclosure wall 29, the shaft portion 35A is locked by the locking portion 30E5 formed by the groove edge of the shaft portion insertion groove 30E4 in the elastic contact piece 30E, thereby holding the front panel 30 in place.

[0055] Furthermore, the protruding tip of the shaft portion 35A is provided with a head (opposing portion) 35B that faces the elastic contact piece 30E. In this configuration, the groove edge of the shaft insertion groove 30E4 in the elastic contact piece 30E is sandwiched between the side edge 29A of the enclosure wall 29 and the head 35B. Therefore, when attaching the front panel 30 to the enclosure wall 29, the elastic contact piece 30E fits between the side edge 29A of the enclosure wall 29 and the head 35B, providing guidance for the attachment process.

[0056] Furthermore, a pair of elastic contact pieces 30E are provided so as to be spaced apart and facing each other along the length of the upper edge 29B, which is included in the multiple edges 29A to 29C and intersects with the side edges 29A. When the front panel 30 is attached to the enclosure wall 29, the pair of elastic contact pieces 30E are elastically contacted with the other of the enclosure wall 29 and the front panel 30. Since the pair of elastic contact pieces 30E are arranged so as to be spaced apart and facing each other along the length of the upper edge 29B, which intersects with the side edges 29A, the front panel 30 can be positioned so that it is centered along the length of the upper edge 29B. This results in a superior appearance.

[0057] Furthermore, the elastic contact piece 30E extends along the entire length of the side edge 29A. In this way, any gaps that may occur between the enclosure wall 29 and the front panel 30 are sealed along the entire length of the side edge 29A by the elastic contact piece 30E. This makes it less likely for external water or other substances to enter the machine room 13 through the gap between the enclosure wall 29 and the front panel 30.

[0058] Furthermore, the showcase (cooled storage) 10 of this embodiment is equipped with the mounting structure for the front panel 30 described above, and the housing 10B constitutes the cooler room 20 and the storage room 19. With a showcase 10 configured in this way, it becomes less likely for external water or other substances to enter the machine room 13, thus reducing the likelihood of malfunctions of the machinery and other equipment inside the machine room 13. This extends the product life of the showcase 10.

[0059] Furthermore, the enclosure 10B includes an insulated box body 11 formed by filling an insulating material between the inner box 11B and the outer box 11A. The insulated box body 11 constitutes the cooler room 20 and the storage room 19, and also constitutes at least the side portion 29A of the enclosure wall 29. In this way, since the insulated box body 11 constitutes at least a part of the machine room 13 (the side portion 29A of the enclosure wall 29), the number of components constituting the machine room 13 can be reduced.

[0060] <Embodiment 2> Embodiment 2 will be explained with reference to Figure 15. This Embodiment 2 shows a modified shape of the elastic contact piece 130E. Note that redundant explanations of the structure, operation, and effects similar to those described in Embodiment 1 will be omitted.

[0061] As shown in Figure 15, the elastic contact piece 130E according to this embodiment has a curved shape from the base end to the extended end. More specifically, the elastic contact piece 130E as a whole has a substantially arc shape, and its central part in the longitudinal direction is the apex 130E3. When the apex 130E3 contacts the inner surface of the side edge 129A of the enclosure wall 129, the elastic contact piece 130E is elastically deformed with the base end as the fulcrum. The curved shape of the elastic contact piece 130E reduces the load acting when the apex 130E3 contacts the inner surface of the side edge 129A of the enclosure wall 129. This reduces the force required to attach the front panel 130 to the enclosure wall 129, improving workability.

[0062] <Embodiment 3> Embodiment 3 will be explained with reference to Figure 16. This Embodiment 3 shows a modification of the shape of the elastic contact piece 230E compared to Embodiment 1 described above. Note that redundant explanations of the structure, operation, and effects, which are the same as those of Embodiment 1, will be omitted.

[0063] As shown in Figure 16, the elastic contact piece 230E according to this embodiment has a shorter first component 230E1 and a longer second component 230E2 compared to the elastic contact piece 30E described in Embodiment 1 (see Figure 8). Therefore, the force required to elastically deform the elastic contact piece 230E is greater than that required in Embodiment 1. Consequently, in the mounting structure of the front panel 230 according to this embodiment, the holding force of the front panel 230 when attached to the surrounding wall 229 is high, but the ease of attaching and detaching the front panel 230 to and from the surrounding wall 229 is low.

[0064] <Embodiment 4> Embodiment 4 will be explained with reference to Figure 17. This Embodiment 4 shows a modification of the shape of the elastic contact piece 330E compared to Embodiment 1 described above. Note that redundant explanations of the structure, operation, and effects, which are the same as those of Embodiment 1, will be omitted.

[0065] As shown in Figure 17, the elastic contact piece 330E according to this embodiment has a longer first component 330E1 and a shorter second component 330E2 compared to the elastic contact piece 30E described in Embodiment 1 (see Figure 8). Therefore, the force required to elastically deform the elastic contact piece 330E is smaller than that required in Embodiment 1. Consequently, in the mounting structure of the front panel 330 according to this embodiment, while the front panel 330 is easy to attach and detach from the surrounding wall 329, the holding force of the front panel 330 when attached to the surrounding wall 329 is lower.

[0066] <Embodiment 5> Embodiment 5 will be described with reference to Figure 18 or Figure 19. This Embodiment 5 shows the front panel 430 and the surrounding wall 429 with markers 36 and 37 added, as in Embodiment 1 described above. Note that redundant explanations of the structure, operation, and effects, which are the same as those of Embodiment 1 described above, will be omitted.

[0067] As shown in Figures 18 and 19, the front panel 430 and the enclosure wall 429 according to this embodiment are marked with markers 36 and 37. Marker 36 is located near the center in the left-right direction on the outer surface of one side 430D that constitutes the front panel 430. Marker 37 is located near the center in the left-right direction on the lower surface of the lower edge 429C (base portion 425) that constitutes the enclosure wall 429. Markers 36 and 37 are positioned so that their positions in the left-right direction are aligned with each other. Therefore, when attaching the front panel 430 to the enclosure wall 429, the worker can visually check the markers 36 and 37 and align the front panel 430 with the enclosure wall 429 so that they are aligned in the left-right direction. This allows the work of attaching the front panel 430 to the enclosure wall 429 to be carried out smoothly, improving work efficiency. By aligning the front panel 430 with the surrounding wall 429 while mounting it, the front panel 430 can be centered so that it is located in the center of the surrounding wall 429 in the left-right direction.

[0068] <Other Embodiments> The technology disclosed herein is not limited to the embodiments described above in the description and drawings, but also includes, for example, the following embodiments.

[0069] (1) Only one elastic contact piece 30E, 130E, 230E, or 330E may be provided.

[0070] (2) It is also possible to swap the arrangement of the first flange 30B with any one of the elastic contact pieces 30E, 130E, 230E, 330E. In that case, the elastic contact pieces 30E, 130E, 230E, 330E will extend along the length direction (left-right direction) of the upper edge portion 29B of the surrounding wall 29, 129, 229, 329, 429 and will be in elastic contact with the inner surface of the upper edge portion 29B.

[0071] (3) It is also possible to provide elastic contact pieces 30E, 130E, 230E, and 330E in place of the first flange 30B. The elastic contact pieces 30E, 130E, 230E, and 330E provided in place of the first flange 30B extend along the length direction (left-right direction) of the upper edge portion 29B of the surrounding walls 29, 129, 229, 329, and 429, and are in elastic contact with the inner surface of the upper edge portion 29B.

[0072] (4) It is also possible to provide elastic contact pieces 30E, 130E, 230E, and 330E in place of the second flange 30C. The elastic contact pieces 30E, 130E, 230E, and 330E provided in place of the second flange 30C extend along the length direction (left-right direction) of the lower edge portion 29C of the enclosure wall 29, 129, 229, 329, and 429, and make elastic contact with the inner surface of the lower edge portion 29C. Note that if the second flange 30C is omitted, the pieces 30D and 430D will also be omitted, so it is preferable to add additional means for fixing the front panels 30, 130, 230, 330, and 430 to the enclosure wall 29, 129, 229, 329, and 429.

[0073] (5) If either (3) or (4) above is applied, the front panels 30, 130, 230, 330, and 430 will be equipped with three elastic contact pieces 30E, 130E, 230E, and 330E. If both (3) and (4) above are applied, the front panels 30, 130, 230, 330, and 430 will be equipped with four elastic contact pieces 30E, 130E, 230E, and 330E.

[0074] (6) The elastic contact pieces 30E, 130E, 230E, and 330E may be of a length that does not reach the total length of the side portions 29A and 129A of the surrounding walls 29, 129, 229, 329, and 429.

[0075] (7) The specific cross-sectional shapes and lengths of the elastic contact pieces 30E, 130E, 230E, and 330E can be changed as appropriate, in addition to those shown in the figures.

[0076] (8) The elastic contact pieces 30E, 130E, 230E, and 330E are not limited to a cantilevered shape, but may also be cantilevered at both ends.

[0077] (9) The elastic contact pieces 30E, 130E, 230E, and 330E are not limited to being provided on the front panels 30, 130, 230, 330, and 430, but may also be provided on the surrounding walls 29, 129, 229, 329, and 429. For example, when the elastic contact pieces 30E, 130E, 230E, and 330E are provided on the side edges 29A and 129A of the surrounding walls 29, 129, 229, 329, and 429, flanges that the elastic contact pieces 30E, 130E, 230E, and 330E are elastically contacted should be provided on the side edges of the panel body 30A that constitutes the front panels 30, 130, 230, 330, and 430. Furthermore, if elastic contact pieces 30E, 130E, 230E, and 330E are provided on the upper edges 29B of the surrounding walls 29, 129, 229, 329, and 429, these elastic contact pieces 30E, 130E, 230E, and 330E will be in elastic contact with the first flange 30B.

[0078] (10) The specific formation range and shape of the shaft insertion groove 30E4 provided in the elastic contact pieces 30E, 130E, 230E, and 330E can be changed as appropriate, in addition to those shown. For example, the shaft insertion groove 30E4 may be formed in a range that does not cut out the top portions 30E3, 130E3 of the elastic contact pieces 30E, 130E, 230E, and 330E (within the range of the second components 30E2, 230E2, and 330E2).
