The front panel 30 is shown in FIGS. 2 to 11, the state seen from the front is shown in FIG. 4, the state seen from the left is shown in FIG. 5, the state seen from above is the state seen from below in FIG. 7 is shown in FIG. 7, and the state seen from behind is shown in FIG. 4 to 8 show the front panel 30 in a state before the decorative resin panel 80 is pasted. Further, FIG. 9 shows a cross section taken along line II in FIG. 8, FIG. 10 shows a cross section taken along line II-II in FIG. 8, and FIG. 8 shows a cross section taken along line III-III in FIG. 11. In the description here, the front and rear (front direction and back direction), left and right, and top and bottom of the air purifier 10 are directions indicated by arrows in FIG.

  The front panel 30 is formed by integrally forming a front surface portion 31, an upper side surface portion 32, a lower side surface portion 33, a right side surface portion 34, and a left side surface portion 35. The front panel 30 is made of resin. Examples of the resin used for the front panel 30 include a thermoplastic resin, and examples of the thermoplastic resin include impact-resistant polyethylene (HIPS) or acrylonitrile-butadiene-styrene resin (ABS resin). The front panel 30 is formed by, for example, injection molding, and the front surface portion 31, the upper side surface portion 32, the lower side surface portion 33, the right side surface portion 34, and the left side surface portion 35 are simultaneously formed.

  The front surface portion 31, the upper side surface portion 32, the lower side surface portion 33, the right side surface portion 34 and the left side surface portion 35 are plate-shaped, and the front surface portion 31, the upper side surface portion 32, the lower side surface portion 33, the right side surface portion 34 and the left side surface portion 35. The plate thickness is set to an appropriate value within a range of 1 to 5 mm. The plate thicknesses of the front surface portion 31, the upper side surface portion 32, the lower side surface portion 33, the right side surface portion 34, and the left side surface portion 35 are all set to the same, for example, 2 mm, for example.

  In the front panel 30, a protrusion 71 that hooks on the upper surface of the main body 20 protrudes downward from the lower surface 32 a of the upper side surface portion 32 in order to fix the front panel 30 to the main body 20. Further, in order to fix the front panel 30 to the main body 20, lock mechanisms 74 and 75 are provided below the right side surface portion 34 and the left side surface portion 35, respectively. By hooking the protrusion 71 of the upper side surface portion 32 on the upper surface of the main body 20 and pushing the lower portion of the front panel 30 toward the main body 20, the lower portion of the front panel 30 is locked by the lock mechanisms 74 and 75 and the front panel 30 is fixed. Is done.

  In the front panel 30, the upper side surface portion 32, the lower side surface portion 33, the right side surface portion 34, the left side surface portion 35, and the front surface portion 31 are connected by a connection portion 40. For example, the connection portion 40 has an arc shape in which a cross section when cut by a plane perpendicular to the upper side surface portion 32 and the front surface portion 31 has a radius of, for example, 3 mm or more and 8 mm or less. In the front panel 30, the upper side surface portion 32 and the right side surface portion 34 are connected by a boundary curved surface portion 36, the upper side surface portion 32 and the right side surface portion 34 are connected by a boundary curved surface portion 37, and the lower side surface portion 33 and the right side surface portion 34 are connected. Are connected by a boundary curved surface portion 38, and the lower side surface portion 33 and the left side surface portion 35 are connected by a boundary curved surface portion 39. These boundary curved surface portions 36 to 39 are arcuate when cut along a plane substantially parallel to the front surface portion 31. The radius of the boundary curved surface portions 36 to 39 is set to 4 mm or less, for example. For example, the radius of the boundary curved surface portions 36 to 39 is about 3 mm. As a result, the front panel 30 has a sharp boundary between the upper side surface portion 32 and the right side surface portion 34, the upper side surface portion 32 and the right side surface portion 34, the lower side surface portion 33 and the right side surface portion 34, and the lower side surface portion 33 and the left side surface portion 35. Presents a beautiful outline. However, when the curvature radius of the boundary curved surface portions 36 and 37 is reduced, the corner portion 51 and the corner portion 51 when the corner portion 51 on the right upper side and the corner portion 51 on the left upper portion collide with the floor surface when the corner portion 51 on the right side falls are compared with the case where the radius of curvature is large. Cracks are likely to occur around 52. Therefore, concave portions 61 and 62 are formed in the corner portions 51 and 52.

  The concave portions 61 and 62 are formed symmetrically with respect to a plane perpendicular to the front surface portion 31 extending vertically in the center of the front surface portion 31 in the left-right direction. Below, the shape of the recessed part 61 is demonstrated in detail, and the detailed description about the shape of the recessed part 62 symmetrical to the recessed part 61 is abbreviate | omitted. As shown in FIG. 11, the recess 61 has a depth Dp1 of 2 mm or more and preferably 3 mm or more. A boundary curved surface portion 36 extends rearward from the corner portion 51 of the front surface portion 31. In the corner portion 51, the first side surface portion in contact with the boundary curved surface portion 36 is the upper side surface portion 32, and the second side surface portion in contact with the boundary curved surface portion 36 is the right side surface portion 34. The boundary curved surface portion 37 extends rearward from the corner portion 52. In the corner portion 52, the first side surface portion in contact with the boundary curved surface portion 37 is the upper side surface portion 32, and the second side surface portion in contact with the boundary curved surface portion 37 is the left side surface portion 35.

  As shown in FIG. 11, the depth Dp1 of the recess 61 means that the front surface portion 31 is not supported in a range of 2 mm from the front end portion 36a of the boundary curved surface portion 36 toward the rear portion. Since the 2 mm boundary curved surface portion 36 that is not supported by the front surface portion 31 is supported only by the upper side surface portion 32 and the right side surface portion 34, the boundary curved surface portion 36, the upper side surface portion 32, and the right side surface portion 34 around the recess 61 are configured. The wall of the concave portion 61 is formed such that when a drop impact is applied to a part of the boundary curved surface part 36, a part of the upper side part 32, and a part of the right side part 34, the front end part 36a or the like is provided on the front part 31 as in the prior art. It is easier to bend than when connected by. These walls of the recess 61 made of resin return to their original state when the impact is eliminated if the deformation due to the bending is an elastic deformation of the resin. As a result, these walls of the recess 61 can absorb the drop impact by bending the wall of the recess 61 when the periphery of the corner 51, particularly the periphery of the front end portion 36a of the boundary curved surface portion 36 collides with the floor surface. The appearance around the corner 51 can be maintained in the state before the collision. When the depth Dp1 of the recess 61 is shallower than 2 mm, the wall of the recess 61 is difficult to bend.

(2-2) Cosmetic resin panel The front panel 30 is provided with a plurality of display openings 45 at the top of the front panel 30. A transparent decorative resin panel 80 is attached to the upper portion of the front panel 30 so as to cover these openings 45 so that dust and water do not enter the openings 45 from the inside. The transparent decorative resin panel 80 is a plate-shaped member made of a transparent resin and having a thickness of 2 mm or more and 5 mm or less, for example. The front panel 30 is provided with a step 46 for attaching the decorative resin panel 80 (see FIG. 5).

  FIG. 12 shows the relationship between the front panel 30 and the decorative resin panel 80 at the location shown in FIG. The decorative resin panel 80 is attached to the front side of the front portion 31 of the front panel 30 with, for example, an adhesive or an adhesive. However, as shown in FIG. 12, the decorative resin panel 80 is not connected to a portion of the boundary curved surface portion 36 that forms the wall of the recess 61. In other words, the portion of the boundary curved surface portion 36 that forms the wall of the recess 61 is a part of the boundary curved surface portion 36 that forms the wall of the recess 61. For example, when the decorative resin panel 80 is connected to the front end portion 36a of the boundary curved surface portion 36, a drop impact is transmitted to the decorative resin panel 80 when the periphery of the corner 51 collides with the floor surface. May be cracked or whitened, or the impact of the front panel 30 may propagate from the decorative resin panel 80 to cause the front panel 30 to crack. Here, whitening means that the resin turns white. Therefore, the decorative resin panel 80 is mounted apart from a part of the boundary curved surface portion 36 that forms the wall of the recess 61, so that the decorative resin panel 80 and the front panel 30 can be prevented from being cracked or whitened. Similarly, the decorative resin panel 80 is not connected to the portion of the upper side surface portion 32 that forms the wall of the recess 61 and the portion of the right side surface portion 34 that forms the wall of the recess 61. In other words, the decorative resin panel 80 is not attached to a part of the upper side surface part 32 and a part of the right side surface part 34 forming the wall of the recess 61.

(3) Features (3-1)
As described above, the air purifier 10 that is an air conditioner includes the main body 20 that performs air conditioning and the resin front panel 30 that is detachably attached to the front surface of the main body 20. The front panel 30 has recesses 61 and 62 that are formed at the corners 51 and 52 of the front portion 31 and absorb the drop impact of the front panel. Since the recesses 61 and 62 for absorbing the drop impact of the front panel 30 are provided in the corners 51 and 52 of the front panel 30, the drop impact is absorbed around the recesses 61 and 62 when the front panel 30 is dropped. it can. As a result, when the front panel 30 falls, it can suppress that a crack arises around the corner | angular parts 51 and 52 of the front panel 30. FIG.

(3-2)
The front panel 30 has boundary curved surface portions 36 and 37 extending rearward from the corner portions 51 and 52 of the front surface portion 31. The first side surface portion and the second side surface portion that are in contact with the boundary curved surface portion of the front panel 30 are the upper side surface portion 32 and the right side surface portion 34 that are in contact with the boundary curved surface portion 36 at the corner portion 51, and the boundary curved surface at the corner portion 52. The upper side surface portion 32 and the left side surface portion 35 are in contact with the portion 37. In the corner 51, a part of the boundary curved surface part 36, a part of the upper side part 32, and a part of the right side part 34 constitute a wall of the recess 61. In the corner 52, a part of the boundary curved surface part 37, a part of the upper side part 32, and a part of the left side part 35 constitute a wall of the recess 62. For these reasons, a part of the boundary curved surface portions 36, 37, a portion of the upper side surface portion 32, or a portion of the right side surface portion 34 and the left side surface portion 35 receives a drop impact, and the recess 61, It is possible to suppress the occurrence of cracks around the corner portions 51 and 52 by bending the wall 62 to alleviate the impact.

(3-3)
In the front panel 30 of the above embodiment, when the thicknesses of the boundary curved surface portions 36 and 37, the upper side surface portion 32, the right side surface portion 34, and the left side surface portion 35 are in the range of 1 mm to 5 mm, the depth of the recesses 61 and 62 is 2 mm. Since the length in the depth direction of the walls of the recesses 61 and 62 can be sufficiently secured by the above, the boundary curved surface portions 36 and 37, the upper side surface portion 32, the right side surface portion 34 or the The left side surface portion 35 can be sufficiently bent to sufficiently suppress cracking.

(3-4)
The cross-sectional shape of the boundary curved surface portions 36, 37 perpendicular to the longitudinal direction of the boundary curved surface portions 36, 37 (the front-rear direction in the above embodiment) is an arc shape, and the radius thereof is 4 mm or less. In the above embodiment, the cross-sectional shapes of the boundary curved surface portions 36 and 37 cut by a plane parallel to the front surface portion 31 are arcuate. Therefore, the curvature radii of the boundary curved surface portions 36 and 37 are 4 mm or less, and an angular sharp outline can be given by such a shape. In addition, even when the radius of curvature is 4 mm or less, the concave portions 61 and 62 can suppress the occurrence of cracks due to the drop impact at the boundary curved surface portions 36 and 37. The same effect can be obtained even if the cross-sectional shape of the boundary curved surface portions 36 and 37 is a shape with a radius of curvature of 4 mm or less that is not an arc shape.

(3-5)
Since the decorative resin panel 80 is separated from the boundary curved surface portions 36 and 37 that form the walls of the recesses 61 and 62, a part of the upper side surface portion 32, a part of the right side surface portion 34, and a part of the left side surface portion 35, The decorative resin panel 80 does not prevent the portions 36 and 37, a part of the upper side surface part 32, a part of the right side part 34 and a part of the left side part 35 from being bent. Further, by covering the recesses 61 and 62 with the decorative resin panel 80, the recesses 61 and 62 are prevented from being noticeable. As a result, the function of suppressing the occurrence of cracking due to a drop impact is prevented from being reduced by the attachment of the decorative resin panel 80, and the effect of suppressing cracking around the corner portions 51 and 52 of the front panel 30 is maintained. The decorative resin panel 80 can prevent the recesses 61 and 62 from being noticeable.
