  As shown in FIG. 5, a windbreak plate 45 (air guide) extending in the left-right direction is attached to the upper wall portion 33 of the front panel 30. As shown in FIG. 9, the windbreak plate 45 is a plate material that closes a gap between the condenser 22 and the front panel 30, and has a function of suppressing a short cycle. In the present embodiment, with the condenser fan 23, air is taken into the machine chamber 20 from the panel member side vent hole 30 </ b> A of the front panel 30, and the condenser 22 is cooled. Here, the short cycle is that air (air in the machine room 20) enters the space between the condenser 22 and the front panel 30 from a location other than the panel member side vent hole 30A. An example of a short cycle air flow prevented by the windbreak plate 45 is indicated by an arrow L1 in FIG. As shown in FIG. 12, the windbreak plate 45 is disposed so as to close the gap between the upper ends of the pair of guide rails 35, 35. Further, the pair of guide rails 35 and 35 are configured to block the gap between the condenser 22 and the front panel 30 and have a function of suppressing a short cycle. An example of the short cycle air flow prevented by the guide rail 35 is indicated by an arrow L2 in FIG.

  As shown in FIG. 3, an L-shaped locking claw 20 </ b> E is provided on the front surface of the bottom wall portion 20 </ b> D constituting the machine room 20. As shown in FIG. 11, the locking claw 20 </ b> E is inserted from below into the through hole 32 </ b> A of the lower wall portion 32 of the front panel 30. Further, as shown in FIG. 5, a roller portion 46 is provided at the upper end portion of the front panel 30. This roller portion 46 constitutes a roller catch together with a locking claw 47 (see FIG. 3) protruding from the opening edge 20B of the opening 20A, and is attached to the locking claw 47 so as to be detachable. Yes. A standing wall 48 that rises upward is provided at the rear end of the lower wall 32.

  In the present embodiment, by releasing the engagement between the roller portion 46 and the locking claw 47, the front panel 30 can be rotated with its lower end portion serving as the rotation center. For this reason, the upper end part of the front panel 30 can be pulled out forward by making the front panel 30 into the forward leaning posture as shown in FIG. In this state, the air filter 60 can be pulled out obliquely upward from the filter insertion hole 34 while the door 16 is kept closed. In the forward tilt posture shown in FIG. 11, for example, the forward pawl 30 is further tilted forward by the locking claws 20 </ b> E being locked from the front with respect to the standing wall portion 48.

  As shown in FIG. 9, a weight 70 is embedded in the upper end portion 65 of the frame portion 62 of the air filter 60. The weight 70 is made of metal, for example, and has a higher specific gravity than the synthetic resin that constitutes the frame portion 62. By providing such a weight 70, the center of gravity G1 (see FIG. 16) of the air filter 60 is arranged at a position higher than the center of the air filter 60 in the vertical direction. Further, instead of embedding the weight 70, the upper end portion 65 of the frame portion 62 is made of a material having a specific gravity larger than that of the lower end portion 66 of the frame portion 62, so that the center of gravity G1 of the air filter 60 can be reduced. It is good also as a structure distribute | arranged to a position higher than the center of an up-down direction.

  Moreover, it is good also as a structure which can adsorb | suck with respect to the front panel 30 by making the weight 70 into a magnet. Further, instead of embedding the weight 70, the thickness of the upper end portion of the air filter 60 (the length in the thickness direction of the air filter 60) is set to a value sufficiently larger than the thickness of the lower end portion 66 of the air filter. Thus, the center of gravity of the air filter 60 may be arranged at a position higher than the vertical center of the air filter 60. For example, as indicated by a two-dot chain line in FIG. 9, the thickness of the upper end portion (indicated by reference numeral 65 </ b> B) of the air filter 60 may be set to the same value as the thickness of the upper wall portion 33.

  Next, the effect of this embodiment will be described. According to the present embodiment, the air filter 60 is attached to the front panel 30. For this reason, for example, a filter insertion hole 34 for inserting the air filter 60 into the front panel 30 is formed, or the front panel 30 is inclined forward, so that a slight gap is formed between the opening edge 20B. Or the like, the air filter 60 can be taken out from the machine room 20. That is, the air filter 60 can be taken out from the machine room without removing the front panel 30.

  Further, according to the present embodiment, the air filter 60 can be pulled out from the machine room 20 through the filter insertion hole 34 without removing the front panel 30.

  Further, according to the present embodiment, the door 16 in the closed state is disposed above the filter insertion hole 34. For this reason, in order to pull out the air filter 60, the door 16 needs to be opened. When the door 16 is opened, the cool air in the storage chamber 11 leaks to the outside, and a downward flow is generated in front of the front panel 30. As a result, it is possible to suppress a situation where dust or the like generated when the air filter 60 is removed enters the storage chamber 11.

  Further, according to the present embodiment, when the air filter 60 is directed to the holding plate member 40 from above through the filter insertion hole 34, the lower end portion 66 of the air filter 60 is held along the upper surface of the holding plate member extending portion 42. It is guided to the plate material standing wall 41 side. Accordingly, the lower end portion 66 of the air filter 60 can be disposed behind the holding plate material standing wall portion 41 (between the holding plate material 40 and the guide rail 35). Here, since the end portion on the front wall portion 31 side in the holding plate material extending portion 42 has a semicircular shape in plan view, the lower end portion of the air filter 60 is less likely to be caught compared to the configuration having a square shape in plan view. Workability is improved.

  A grip 67 is provided at the upper end of the air filter 60, and the grip 67 is disposed above the upper wall 33 of the front panel 30. The air filter 60 can be easily pulled upward by gripping the grip portion 67. Moreover, since the grip part 67 is visually observed by the user, the user can be aware of the presence of the air filter 60 and can prompt the user to clean the air filter 60.

  In the thickness direction of the air filter 60, the length of the longitudinal bone 63 of the frame portion 62 is set to a value larger than the length of the lateral bone 64. When the air filter 60 is inserted into the filter insertion hole 34, it is possible to suppress a situation in which the lateral bone 64 is caught on the edge of the filter insertion hole 34.

  Further, the lower end portion 66 of the air filter 60 is smaller in width and thickness than the upper portion 71 of the air filter 60. Thus, the air filter 60 can be easily inserted into the filter insertion hole 34 from above, and the gap between the inner surface of the filter insertion hole 34 and the upper portion 71 can be reduced. Can be suppressed. Note that only one of the lower end portion 66 of the air filter 60 may be smaller in width or thickness than the upper portion 71 of the air filter 60.

  In addition, by providing a windproof plate 45 that closes the gap between the condenser 22 and the front panel 30, a situation in which air that has passed through the condenser 22 enters the space between the condenser 22 and the front panel 30 (short circuit). Cycle).

  Further, the filter insertion hole 34 has a long and square shape, and a corner portion has an R shape. Thereby, the situation where dust etc. accumulate in the corner of filter penetration hole 34 can be controlled.

  In addition, characters are written on the upper surface of the air filter 60. In the present embodiment, when the user opens the door 16, the characters written on the upper surface of the air filter 60 can be seen by viewing the front panel 30 from above. For this reason, for example, by writing a sentence for urging the air filter 60 on the upper surface of the air filter 60, the cleaning can be promoted.

  Further, the lateral bone 64 has a sectional view shape, and the corner portion has an R shape. When the air filter 60 is inserted into the filter insertion hole 34, it is possible to more reliably suppress the situation where the lateral bone 64 is caught on the hole edge portion of the filter insertion hole 34.

  Further, the front panel 30 is rotatably attached to a wall portion (bottom wall portion 20D) constituting the machine room so that the lower end portion of the front panel 30 is a rotation center. Is arranged at a position higher than the center of the air filter 60 in the vertical direction. By setting the front panel 30 to a forward tilted posture (a posture toward the front as it goes upward), the upper end portion (the filter insertion hole 34) of the front panel 30 can be displaced forward, and the air filter 60 is inserted into the filter insertion hole. The machine room 20 can be easily taken in and out through 34. The center of gravity G <b> 1 of the air filter 60 is disposed at a position higher than the center of the air filter 60 in the vertical direction.

  For this reason, when the air filter 60 is inserted into the filter insertion hole 34 from above while the front panel 30 is in the forward inclined posture, the air filter 60 is likely to be in the forward inclined posture. That is, the situation where the lower end portion 66 of the air filter 60 is rubbed against the front wall portion 31 of the front panel 30 (the air filter in such a state is simply indicated by a two-dot chain line in FIG. 11 and denoted by reference numeral 60A) is suppressed. be able to. As a result, the air filter 60 can be easily inserted into the filter insertion hole from above. Since the front wall portion 31 of the front panel 30 is formed with a plurality of panel member side vent holes 30A, the friction resistance when the lower end portion 66 rubs against the front wall portion 31 is increased, and the air filter 60 However, in this embodiment, such a situation can be suppressed.

  Further, the upper end portion 65 of the air filter 60 is configured to overlap the hole edge portion of the filter insertion hole 34 in the upper wall portion 33 from above. Thereby, the situation where dust etc. enter the filter insertion hole 34 can be suppressed.

  The net 61 of the air filter 60 has a square shape, the lower end 66 of the frame 62 has a shape that follows the shape of the lower end 61A of the net 61, and the lower end 61A of the net 61 is attached. 66A to be pasted, and a lower end constituting portion 66B which is disposed below the pasted portion 66A and constitutes the lower end of the frame portion 62 and decreases in width toward the lower end. By providing the lower end constituting portion 66 </ b> B, the air filter 60 can be easily inserted into the filter insertion hole 34. If the net 61 is attached to the lower end component 66B, it is necessary to cut the net 61 in a shape that follows the shape of the lower end component 66B. In this regard, by providing the part to be pasted 66A, the net part 61 can be formed into a square shape, and therefore, a situation in which an end material is generated can be suppressed.

  A metal weight 70 is embedded in the upper end portion 65 of the frame portion 62 of the air filter 60. By burying the weight 70, the center of gravity G1 of the air filter 60 can be disposed at a position higher than the center of the air filter 60 in the vertical direction. Further, by embedding a magnet as a weight 70 in the upper end portion of the frame portion 62, the upper end portion 65 of the frame portion 62 can be fixed to the metal front panel 30 via the magnet. Thereby, the vibration of the air filter 60 can be suppressed.

  A nonwoven fabric 68 is attached to the surface of the air filter 60 on the condenser 22 side, and a pair of protective rails sandwiching the nonwoven fabric 68 from the left and right directions of the showcase 10 on the surface of the air filter 60 on the condenser 22 side. 69, 69 are provided. Oil can be adsorbed by the nonwoven fabric 68. In addition, when the air filter 60 is inserted into the filter insertion hole 34 by the pair of protective rails 69, 69, the situation in which the nonwoven fabric 68 comes into contact with the hole edge of the filter insertion hole 34 can be suppressed. The situation where it peels from the air filter 60 can be suppressed.
