Therefore, in a state where the frame-shaped member 80 is attached to the filter insertion hole 31, the frame-shaped member upper wall portion 81 and the frame-shaped member rear wall portion 82 are formed by the front hole edge portion 32A and the lower hole edge portion 33A. It is elastically deformed in a shape following 90 degrees (so as to form 90 degrees). As a result, the frame-shaped member upper wall portion 81 (more specifically, the holding projection portion 81B) is pressed against the front hole edge portion 32A from the rear, and the frame-shaped member rear wall portion 82 (more specifically, the holding projection portion 81B). ) Is configured to be pressed against the lower hole edge 33A from above. The angle D2 formed by the front hole edge 32A and the lower hole edge 33A is not limited to 90 degrees and can be changed as appropriate. In addition, the structure which sets the angle D1 larger than the angle D2 demonstrates a function independently of the other structure illustrated in this specification. That is, in the frame-shaped member 80, the structure which sets the angle D1 larger than the angle D2 may be provided independently, and may be used in combination with another structure.
Furthermore, the frame-shaped member 80 includes a protruding portion 83 (see also FIG. 13) inserted into a through hole 33B (see also FIG. 5) formed in the lower hole edge portion 33A. The through-hole 33B may be formed in the frame-shaped member 80, and the protrusion 83 may be formed in the lower hole edge portion 33A.

  Moreover, the frame-shaped member 80 is provided with the filter support part 84 which has the filter support surface 84A which supports the lower end part of the air filter 40, as shown in FIG.8 and FIG.14.

The filter support surface 84A is flush with an inner surface 63A (see FIG. 10, an upper surface of the rib 64B) of a guide rail 63 described later. Further, as shown in FIG. 8, the air filter 40 includes a filter locking portion 45 that locks the filter support portion 84 from the condenser 22 side (right side in FIG. 8). Further, a frame-like member side magnet 84B is embedded in the filter support portion 84, and a filter-side magnet 46 that is attracted to the frame-like member side magnet 84B is embedded in the air filter 40. Thereby, the air filter 40 is being fixed via the magnet with respect to the filter support part 84 (frame-shaped member 80). That is, the air filter 40 is fixed to the front panel 30 via the frame-shaped member 80.

  Next, the configuration of the filter holding member 60 will be described. As shown in FIG. 16, the filter holding member 60 has a substantially box shape penetrating in the front-rear direction, and has a configuration in which the front is covered by the air filter 40 and the rear is covered by the condenser 22. Specifically, the filter holding member 60 includes a pair of side wall portions 61 and 61 and an upper wall portion 62. The side wall portion 61 includes a guide rail 63 and a cover portion 65.

  The side wall portion 61 is made of, for example, a synthetic resin, and the upper wall portion 62 is made of, for example, a metal plate material. As shown in FIG. 16, the front end portion and the rear end portion of the upper wall portion 62 are bent portions 62A that are bent so as to protrude upward. A plate-like protrusion 61 </ b> D that covers the bent part 62 </ b> A from the side is provided at the upper end of the side wall 61. The cover portion 65 constitutes most of the rear side of the side wall portion 61, and is configured to close the gap between the guide rail 63 and the condenser 22.

  That is, the filter holding member 60 has a function of a wind tunnel connecting the air filter 40 and the condenser 22 in addition to the function of holding the air filter 40. Thereby, the condenser fan 23 is driven, so that the air sucked into the filter holding member 60 through the air filter 40 is directed to the condenser 22. In other words, by providing the filter holding member 60 that is a wind tunnel, it is possible to suppress the situation where air does not pass through the air filter 40 and to the condenser 22, and the situation where dust or the like adheres to the condenser 22 is suppressed. can do.

  In addition, as shown in FIG. 16, the machine room 20 is pulled out from the cooler room side disposed below the machine room 20 and connected to a control unit 25 (control box) in the machine room 20.

As shown in FIG. 17, the insertion hole cover 66 is provided integrally with the hole edge portion of the wiring insertion hole 65A in the cover portion 65 via an integral hinge 66A. Thereby, the insertion hole cover 66 is provided so as to be rotatable with respect to the hole edge portion of the wiring insertion hole 65A. For this reason, when passing the wiring 26 through the wiring insertion hole 65A, the wiring insertion hole 65A can be opened by rotating the insertion hole cover 66. Further, on the outer surface of the cover portion 65, a flange portion 65C having a U-shape is formed at the hole edge portion of the wiring insertion hole 65A.

  In addition, as shown in FIG. 16, on the bottom wall 35 of the machine room 20, the wiring that covers the wiring 27 arranged in the machine room 20 from above and in front is provided at a position corresponding to the rear end of the cover portion 65. A cover 28 is provided. The wiring cover 28 is disposed between a pair of cover portions 65 and 65 provided corresponding to the pair of guide rails 63 and 63. The cover 65 is formed with a notch 65B (see also FIG. 7) through which the wiring 27 extending laterally from the wiring cover 28 can pass. Further, an upper surface covering portion 67 that covers the upper surface of the wiring cover 28 is provided at the hole edge portion of the notch portion 65B. Further, as shown in FIG. 7, the bottom wall 35 of the machine room 20 has a stepped portion 35A where the condenser 22 is disposed, which is higher than the front portion thereof. A gap S1 (see also FIG. 24) is provided between the portion 35A and the portion 35A. And the standing wall part 28A which covers the clearance gap S1 provided between the bottom wall 35 of the machine room 20 and the bottom face of the condenser 22 is provided in the edge part by the side of the condenser 22 in the wiring cover 28. As shown in FIG. (See FIGS. 7 and 16). Further, the wiring cover 28 is detachably attached to the portion 35A of the bottom wall 35 with screws. When cleaning the condenser 22, by removing the wiring cover 28, a drain pan (not shown) for receiving water during cleaning can be inserted into the gap S1. Examples of the wirings 26 and 27 described above include wiring drawn from a thermistor (thermistor for measuring internal temperature, not shown) provided in the cooler chamber, but is not limited thereto. Not. Further, only one of the wirings 26 and 27 may be provided.

  Next, the configuration of the air filter 40 will be described. As shown in FIG. 18, the air filter 40 has a net-like net part 51 having a square shape as a whole and a frame part 50 held by the net part 51. The frame 50 includes a rectangular frame-shaped outer frame 52, a vertical bone 55 extending in the vertical direction inside the outer frame 52, and a plurality of horizontal frames intersecting the vertical bone 55 inside the outer frame 52. And a bone 53. The net part 51 is arranged so as to cover almost the entire surface of the frame part 50. Each lateral bone 53 is provided so as to connect the longitudinal bone 55 and the outer frame 52, and extends so as to be inclined downward toward the longitudinal bone 55. A side end portion of the outer frame 52 constitutes a side end portion of the air filter 40, and a rib 54 is formed on the front surface of the side end portion of the outer frame 52. That is, the rib 54 extends along the side end of the air filter 40.

  As shown in FIG. 19, a recess 47 that opens upward is formed at the lower end of the air filter 40. The recesses 47 extend in the left-right direction and are disposed on both sides in the left-right direction at the lower end of the air filter 40. In the air filter 40, the frame part 50 and the filter holding part 41 are connected by a connecting part 48 having a plate shape. The connecting portion 48 is formed with a through hole 50A extending in the left-right direction, and an oil guide 56 is attached to the hole edge of the through hole 50A as shown in FIG. As shown in FIGS. 20 and 21, the oil guide 56 is assembled to the air filter 40 from the rear. The oil guide 56 includes an engaging portion 57 (see also FIG. 22) that engages with a hole edge portion of the through hole 50A, and a guide main body portion 58 that is inserted into the through hole 50A.

  The guide main body portion 58 is arranged in a posture that is inclined downward toward the front panel 30, and as shown in FIG. 20, most of the rear side protrudes from the back side of the air filter 40. It is arranged to cover the back side from below. And as shown in FIG. 8, the clearance gap is provided between the upper surface 58A of the guide main-body part 58, and the inner surface of 50 A of through-holes. The front end portion of the guide main body 58 is disposed on the front side of the air filter 40. Thereby, when the oil adhering to the air filter 40 goes to the rear surface of the air filter 40 through the mesh portion 51 and the oil falls, the oil guide 56 guides the oil to the front side of the air filter 40. Can do.

  Further, as shown in FIG. 8, a protrusion 48 </ b> A is formed on the back surface of the connecting portion 48. The protrusion 48 </ b> A (seal part) extends along the left-right direction and protrudes toward the bottom wall 35 of the machine room 20. Thereby, the gap between the rear surface of the air filter 40 and the bottom wall 35 of the machine room 20 is closed by the protrusion 48A. In the present embodiment, as shown in FIG. 8, the protrusion 48A is not in contact with the bottom wall 35, and the gap between the rear surface of the air filter 40 and the bottom wall 35 is partially blocked. However, the protrusion 48 </ b> A may be configured to abut against the bottom wall 35. Further, as shown by a two-dot chain line in FIG. 8, an oil guide seal portion 56 </ b> A that closes a gap between the rear surface of the air filter 40 and the bottom wall 35 of the machine chamber 20 is provided on the rear surface of the oil guide 56. Also good.

  Next, the effect of this embodiment will be described. According to the present embodiment, the air filter 40 can be pulled out obliquely downward from the machine room 20 through the filter insertion hole 31 with the front panel 30 closed. For this reason, since it is not necessary to open the front panel 30, the air filter 40 can be pulled out easily. Further, since the air filter 40 is configured to be inclined downward toward the front panel 30, a space can be provided between the front panel 30 and the air filter 40. For this reason, by operating the condenser fan 23, it is possible to blow air from the air filter 40 toward the condenser 22 through the space. As a result, it is not necessary to form an air intake hole in the front panel 30, and the design can be further improved.

  Further, the user can easily pull out the air filter 40 by holding the filter holding portion 41. Since the filter gripping portion 41 has a shape protruding downward, it is difficult for dust to collect. The user can easily pull out the air filter 40 by inserting his / her hand into the first recess 41 </ b> A and the second recess 41 </ b> B of the filter grip 41.

  The air filter 40 is fixed to the front panel 30 via a magnet 42. For this reason, the air filter 40 can be detachably fixed, and a situation in which abnormal noise is generated due to vibration during operation of the cooling storage 10 can be suppressed.

  Further, a frame-shaped member 80 having a frame shape through which the air filter 40 can be inserted is attached to the hole edge portion of the filter insertion hole 31. A situation in which the hole edge portion of the filter insertion hole 31 is directly visible can be suppressed, and the design property can be further improved.

  Moreover, the air filter 40 is being fixed to the frame-shaped member 80 via the magnet (The filter side magnet 46 and the frame-shaped member side magnet 84B). The air filter 40 can be detachably fixed, and a situation in which abnormal noise is generated due to vibration during operation of the cooling storage 10 can be suppressed. And by providing a magnet in both the air filter 40 and the frame-shaped member 80, the air filter 40 can be placed at a more accurate position than a configuration in which a magnet is provided in only one (the configuration in which the other is made of metal). Can be fixed.

  Further, when the air filter 40 is inserted into the machine chamber 20 from the filter insertion hole 31, the air filter 40 can be inclined by the filter support surface 84A of the frame-shaped member 80, and the air filter 40 can be easily inserted. .

  The air filter 40 includes a filter locking portion 45 that locks the filter support portion 84 from the condenser 22 side. As a result, the air filter 40 can be more reliably prevented from falling off. Furthermore, the air filter 40 can be more securely fixed to the frame-shaped member 80 by using both the filter locking portion 45 and the magnet (the filter-side magnet 46 and the frame-shaped member-side magnet 84B).

  Further, the front hole edge 32A of the front panel 30 is fitted into the front fitting groove 81A of the frame member 80, and the lower hole edge 33A of the front panel 30 is fitted into the lower fitting groove 82A of the frame member 80. The frame-shaped member 80 can be attached by making it fit. In such a configuration, the frame-shaped member upper wall portion 81 and the frame-shaped member rear wall portion 82 need to be elastically deformed and attached to the front hole edge portion 32A and the lower hole edge portion 33A. Here, the front fitting groove 81A is opened upward, and the lower fitting groove 82A is opened forward. For this reason, when the frame-shaped member upper wall portion 81 is elastically displaced downward and the frame-shaped member rear wall portion 82 is elastically displaced forward, both wall portions hardly interfere with each other, and the amount of displacement can be easily obtained. For this reason, both hole edge part 32A, 33A can be easily fitted with respect to both fitting groove 81A, 82A.

  Further, the groove width of the front fitting groove 81A is set to a value larger than the thickness of the front hole edge portion 32A, and the front hole edge portion 32A is 3 of the opening end portions of the holding protrusion 81B and the holding recess 81C. It is held at a point. For this reason, the groove width of the front fitting groove 81A can be increased while holding the front hole edge portion 32A, and the front fitting groove can be easily formed by the forming die.

  Of the opening end portion of the front fitting groove 81A in the frame-shaped member upper wall portion 81, the upper surface 81D of the front opening end portion is disposed at a lower position than the upper surface 81E of the rear opening end portion. ing. In this way, at the rear opening end portion, the front opening edge portion 32A is securely locked, and the front opening end portion top surface 81D visually recognized by the user is lowered, so that the front side It is possible to make the opening end of the conspicuous. For this reason, it is possible to achieve both the improvement of the holding force of the frame-shaped member 80 and the improvement of the design.

  Further, the frame-shaped member 80 includes a protruding portion 83 that is inserted into a through hole 33 </ b> B formed in the panel lower wall portion 33 of the front panel 30. The frame-shaped member 80 can be fixed to the panel lower wall portion 33.

  Of the opening end portions of the front fitting groove 81A in the frame-shaped member upper wall portion 81, the upper surface 81E of the rear opening end portion has a shape in which the central portion in the longitudinal direction of the frame-shaped member 80 bulges upward. Make. When the front hole edge 32A is fitted into the front fitting groove 81A, it is necessary to bend and deform the frame-shaped member upper wall 81. By bulging upward the central portion in the longitudinal direction, which is relatively easy to bend, the rear opening end is more reliably locked to the front hole edge portion 32A and the assemblability of the frame-shaped member 80 is secured. can do.

  Further, in the frame-shaped member 80 in a state where it is removed from the filter insertion hole 31, the angles formed by the frame-shaped member upper wall portion 81 and the frame-shaped member rear wall portion 82 are the front hole edge portion 32A and the lower hole edge portion 33A. It is set to a value larger than the angle formed by For this reason, in a state where the frame-shaped member 80 is mounted in the filter insertion hole 31, the frame-shaped member upper wall portion 81 can be elastically pressed against the front hole edge portion 32A, and the frame-shaped member rear wall portion 82 can be pressed. Can be elastically pressed against the lower hole edge 33A. Thereby, the frame-shaped member 80 can be more reliably attached to the filter insertion hole 31.

  Further, by providing the cover portion 65 that closes the gap between the guide rail 63 and the condenser 22, the condenser 2 is passed through the gap between the guide rail 63 and the condenser 22 (in other words, not through the air filter 40). The situation where the air goes can be suppressed.

  Further, by providing the wiring insertion hole 65 </ b> A in the cover portion 65, it is possible to suppress a situation where the cover portion 65 prevents the wiring 26 from being routed when the wiring 26 is accommodated in the machine room 20. Further, by providing the insertion hole cover 66, when the wiring is not inserted, it is possible to suppress the situation where the air is directed to the condenser 22 through the wiring insertion hole 65A (in other words, not through the air filter 40).

  Further, the guide rail 63 includes a bottom wall locking portion 61 </ b> B that locks to the front end portion of the bottom wall 35 of the machine room 20. Thereby, for example, when the guide rail 63 is assembled with the screw 61A, it is possible to prevent the guide rail 63 from rotating about the vertical direction as the rotation axis.

  Further, as the air filter 40 moves downward, the lower part of the air filter 40 is lowered closer to the vertical direction by the guide rail 63 than the linear configuration by making the air filter 40 curved toward the front panel 30. Can be supported from. As a result, the air filter 40 can be more reliably prevented from falling off.

  In addition, the wiring 27 can be protected by the wiring cover 28. Further, by providing the upper surface covering portion 67, it is possible to close the gap between the hole edge portion of the notch portion 65B and the wiring cover 28, and pass through the notch portion 65B from the outside of the pair of cover portions 65, 65 ( It is possible to suppress the situation where air is directed to the condenser 22 (without passing through the air filter 40). In addition, by providing the gap S1 between the bottom wall 35 of the machine room 20 and the bottom surface of the condenser 22, for example, a drain pan that receives water when the condenser 22 is washed can be inserted into the gap S1. . Furthermore, by providing the standing wall portion 28A that covers the gap S1 from the front, a situation in which air is directed to the rear of the condenser 22 through the gap S1 (in other words, a situation in which the air does not pass through the condenser 22 and the condensation capacity is reduced). ) Can be suppressed.

  Further, the air filter 40 is fixed to the front panel 30 via a frame-shaped member 80. For this reason, when the front panel 30 is opened, the air filter 40 also moves together with the front panel 30, and the air filter 40 and the guide rail 63 interfere with each other. Therefore, it is difficult to open and close the front panel 30. That is, it is preferable that the air filter 40 be removed from the front panel 30 when the user opens and closes the front panel 30. The user can prompt the user to clean the air filter 40 by removing the air filter 40.

  Further, a concave portion 47 opened upward is formed at the lower end portion of the air filter 40. When oil or the like attached to the air filter 40 flows downward along the surface of the air filter 40, the oil can be stored in the recess 47.

  A rib 54 extending along the side end of the air filter 40 is formed on the front surface of the side end of the air filter 40. It is possible to suppress the situation where oil or the like attached to the air filter 40 flows from the side end portion.

  An oil guide 56 is attached to the air filter 40. When oil or the like adheres to the front surface of the air filter 40, a part of the oil filter may go toward the rear surface of the air filter 40 through a gap (mesh 51) of the air filter 40. When oil accumulates on the rear surface of the air filter 40 and falls, the oil guide 56 can guide the oil to the front side of the air filter 40.

  Further, the lateral bone 53 of the air filter 40 extends so as to be inclined downward toward the longitudinal bone 55. The oil adhering to the air filter 40 can be directed to the longitudinal bone 55 along the transverse bone 53. The oil that has reached the longitudinal bone 55 is accommodated in the recess 47 along the longitudinal bone 55. Thereby, the situation where oil flows down from air filter 40 can be controlled.

  In addition, a protrusion 48 </ b> A that closes the gap between the rear surface of the air filter 40 and the bottom wall 35 of the machine room 20 is provided. It is possible to suppress a situation in which air passes through the gap between the rear surface of the air filter 40 and the bottom wall 35 of the machine room 20 (without passing through the air filter 40) toward the condenser 22.

  Further, an oil guide seal portion 56 </ b> A that closes a gap between the rear surface of the air filter 40 and the bottom wall 35 of the machine chamber 20 may be provided on the rear surface of the oil guide 56. In this way, it is possible to suppress a situation in which air passes through the gap between the rear surface of the air filter 40 and the bottom wall 35 of the machine room 20 (without passing through the air filter 40) toward the condenser 22.

  Further, the filter insertion hole 31 is provided in the central portion of the front panel 30 in the longitudinal direction. Compared to the configuration in which the filter insertion hole 31 is provided at the longitudinal end of the front panel 30, the filter insertion hole 31 (and thus the filter grip 41 of the air filter 40) is easily noticeable, and the air filter 40 is cleaned. Can prompt the user.

  Further, the filter insertion hole 31 is disposed above the handle 16 </ b> A provided in the door 16. When the user grips the handle 16A and opens and closes the door 16, the filter insertion hole 31 is easily noticeable, and the user can be encouraged to clean the air filter 40.

  The filter insertion hole 31 may be disposed below the window portion 30B. In this way, when the user views the display unit 30A through the window 30B, the filter insertion hole 31 is easily noticeable, and the user can be prompted to clean the air filter 40.

<Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to FIG. In the present embodiment, the configuration of the frame-like member is different from that of the first embodiment. Note that the same portions as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted. As shown in FIG. 23, the frame-shaped member 180 of the present embodiment is in a state (natural state) before being attached to the filter insertion hole 31, and the frame-shaped member upper wall portion 181 has a central side in the longitudinal direction (left-right direction). It has a curved shape that protrudes upward compared to both end sides.

  For this reason, the bottom surface of the front-side fitting groove 181A (see the two-dot chain line in FIG. 23) also has a curved shape in which the center side protrudes upward. In contrast, the front hole edge 32A (see FIG. 4) has a linear shape along the horizontal direction. Therefore, in a state where the frame-shaped member 180 is attached to the filter insertion hole 31, the frame-shaped member upper wall portion 181 is elastically deformed following the shape of the front hole edge portion 32A, and as a result, the bottom surface of the front fitting groove 181A Is pressed against the front hole edge 32A from below. Thereby, the situation which a clearance gap produces between 32 A of front side hole edge parts (as a result, panel front wall part 32) and the frame-shaped member upper wall part 181 can be suppressed, and design nature can be made higher. In addition, the center part in the frame-shaped member upper wall part 181 which makes long shape is easy to bend and deform compared with the both ends. For this reason, compared with the structure which makes the shape which the both ends in the longitudinal direction of the frame-shaped member upper wall part 181 protrude compared with a center part, it is the structure which makes it easy to fit the front side hole edge part 32A to the front side fitting groove 181A. It has become.

As shown in FIG. 24, the filter holding member 260 of this embodiment is composed of a pair of guide rails 263 and 263 made of synthetic resin. A cover portion 265 (shown by a two-dot chain line in FIG. 24) is disposed separately from the guide rail 263 between the guide rail 263 and the condenser 22. The cover portion 265 includes a pair of side wall portions 266 and 266 and an upper wall portion 267 that are disposed to face each other, and is configured by bending a metal plate.

  The distance between the air filter 40 and the condenser 22 is appropriately set according to the size of the cooling storage 10. By making the cover part 265 separate from the guide rail 263, it is possible to easily cope with this by changing the length of the cover part 265 according to the distance between the air filter 40 and the condenser 22. Further, since the cover portion 265 is a metal plate, it can be easily formed as compared with the case where it is made of a synthetic resin.

<Embodiment 4>
Next, Embodiment 4 of the present invention will be described with reference to FIG. In the present embodiment, the arrangement mode of the air filter is different from those in the above embodiments.
