<Heat pump unit 2>
FIG. 3 is a front view of a heat pump unit according to an embodiment of the present invention. In FIG. 3, the cover 80 attached to the side plate 60 covers a range from the vicinity of the upper end of the side plate 60 to the vicinity of the lower end, and a portion covering the pipe joint 70 swells outward. The cover 80 has a plurality of attachment claws 81 at the upper part, the central part, and the lower part. For convenience of explanation, the cover 80 is referred to as an upper attachment claw 811, a central part attachment claw 812, and a lower attachment claw 813 in order from the upper part.

  The upper mounting claw 811, the center mounting claw 812 and the lower mounting claw 813 are inserted into the mounting holes provided in the side plate 60 and hooked inside the side plate 60, thereby fixing the cover 80 to the side plate 60.

<Mounting structure of cover 80>
(Upper mounting claw 811)
FIG. 4 is a cross-sectional view of the heat pump unit of FIG. 3 taken along line AA above the upper mounting claw. In FIG. 4, the upper part of the side plate 60 has a first surface 61 and a second surface 62 that project toward the inside of the casing 50. The second surface 62 protrudes further toward the inside of the casing 50 than the first surface 61. The upper mounting claw 811 is located between the virtual surface P <b> 1 including the first surface 61 and the virtual surface P <b> 2 including the second surface 62.

  FIG. 5 is an enlarged view of a portion X in FIG. 4, and FIG. 6 is a cross-sectional view taken along line DD in FIG. 5 and 6, the first surface 61 is formed by drawing. The second surface 62 is formed by further drawing the first surface 61. At this time, a third surface that connects the first surface 61 and the second surface 62 is formed.

  A rectangular hole is formed in the first surface 61 in advance, and one long side of the hole is left on the first surface 61, and the other long side is drawn simultaneously with the drawing of the second surface 62. By doing so, the attachment hole 64 opened in the vertical direction is formed. Since the upper mounting claw 811 is inserted into the mounting hole 64, it is referred to as an upper mounting hole 641 for convenience. The upper mounting hole 641 is located in a region where the first surface 61 changes to the third surface 63.

  The upper mounting claw 811 of the cover 80 has a shape extending vertically upward. The upper mounting claw 811 enters upward from below the upper mounting hole 641 and pushes the first surface 61 of the side plate 60 outward. As a result, a drag force is generated between the first surface 61 and the upper mounting claw 811, and the upper portion of the cover 80 is fixed to the side plate 60.

(Center mounting claw 812)
FIG. 7 is a cross-sectional view of the heat pump unit of FIG. 3 taken along the line BB above the center mounting claw. In FIG. 7, the central portion of the side plate 60 has a first surface 61 and a second surface 62 that project toward the inside of the casing 50 in the same manner as the upper portion. The second surface 62 protrudes further toward the inside of the casing 50 than the first surface 61. The center mounting claw 812 is located between a virtual surface P1 including the first surface 61 and a virtual surface P2 including the second surface 62.

  8 is an enlarged view of a portion Y in FIG. 7, and FIG. 9 is a cross-sectional view taken along line EE in FIG. 8 and 9, the first surface 61 is formed by drawing. The second surface 62 is formed by further drawing the first surface 61. At this time, a third surface that connects the first surface 61 and the second surface 62 is formed.

  A rectangular hole is formed in the first surface 61 in advance, and one long side of the hole is left on the first surface 61, and the other long side is drawn simultaneously with the drawing of the second surface 62. By doing so, the attachment hole 64 opened in the vertical direction is formed. Since the center mounting claw 812 is inserted into the mounting hole 64, this is referred to as a center mounting hole 642 for convenience. The center mounting hole 642 is sandwiched between the third surfaces 63 on both sides.

  The center part mounting claw 812 of the cover 80 has a shape extending vertically upward. The central portion mounting claw 812 enters from the lower side of the central portion mounting hole 642 upward and pushes the first surface 61 of the side plate 60 outward. As a result, a drag force is generated between the first surface 61 and the central portion mounting claw 812, and the central portion of the cover 80 is fixed to the side plate 60.

(Lower mounting claw 813)
FIG. 10 is a cross-sectional view of the heat pump unit of FIG. 3 taken along line CC above the lower mounting claw. In FIG. 10, the lower portion of the side plate 60 has a first surface 61 and a second surface 62 that project toward the inside of the casing 50 in the same manner as the upper portion. The second surface 62 protrudes further toward the inside of the casing 50 than the first surface 61.

  In the lower part of the side plate 60, a pipe joint mounting plate 71 that holds the pipe joint 70 faces the second surface 62. The pipe joint mounting plate 71 has a protrusion 72 that protrudes toward the inside of the casing 50. The protrusion 72 is formed by bending the outer periphery of the pipe joint mounting plate 71. The lower mounting claw 813 is positioned between a virtual surface P1 including the first surface 61 and a virtual surface P3 including the tip of the protruding portion 72 of the pipe joint mounting plate 71.

  11 is a cross-sectional view taken along line FF in FIG. In FIG. 10, the first surface 61 is formed by drawing. The second surface 62 is formed by further drawing the first surface 61. At this time, a third surface that connects the first surface 61 and the second surface 62 is formed.

  A rectangular mounting hole 64 is formed in the first surface 61 in advance. Since the lower attachment claw 813 is inserted into the attachment hole 64, this is referred to as a lower attachment hole 643 for convenience. The lower mounting hole 643 is located in the vicinity of the third surface 63.

  The lower mounting claw 813 of the cover 80 has a shape extending vertically upward. The distance of the lower mounting claw 813 protruding to the inside of the casing 50 is larger than that of the upper mounting claw 811 and the center mounting claw 812. This is because the lower part of the cover 80 bulges outward so as to cover the pipe joint 70 and is heavier than the upper part and the central part of the cover 80, and the load acting on the lower mounting claw 813 is the upper mounting claw 811 and the central part. It is larger than the mounting claw 812, and the volume of the lower mounting claw 813 needs to be increased. As a result, the lower mounting claw 813 protrudes from the virtual surface P2 including the second surface 62. However, since the protruding portion 72 of the pipe joint mounting plate 71 protrudes further toward the inside of the casing 50 than the lower mounting claw 813, the lower mounting claw 813 includes the virtual surface P1 and the tip of the protruding portion 72. It falls within the virtual plane P3.

  The lower mounting claw 813 enters from the lower mounting hole 643 and pushes the first surface 61 of the side plate 60 outward. As a result, a drag force is generated between the first surface 61 and the lower mounting claw 813, and the lower portion of the cover 80 is held by the side plate 60.

<Soundproof material 90>
As shown in FIGS. 9 and 10, the soundproof material 90 is in close contact with the second surface 62 and the pipe joint mounting plate 71. The soundproofing material 90 is wound around a device such as a compressor housed in the casing 50, and the inside of the side plate 60 is pushed outward by the soundproofing material 90 during and after assembly.

  Since the second surface 62 protrudes most at the center portion of the side plate 60 and the protrusion 72 of the pipe joint mounting plate 71 protrudes most at the lower portion of the side plate 60, the second surface 62 and the protrusion 72 are always The soundproofing material 90 is contacted, and the soundproofing material 90 is prevented from contacting the center mounting claw 812 and the lower mounting claw 813. In other words, the soundproof material 90 can be pressed to the inner side of the side plate 60 without worrying about damage to the center mounting claw 812 and the lower mounting claw 813.

<Features>
(1)
In the heat pump unit 2, the side plate 60 of the casing 50 has a first surface 61 and a second surface 62 on the inner side, and the second surface 62 projects toward the inner side of the casing 50 from the first surface 61. . A cover 80 is attached to the casing 50 via an attachment claw 81. The mounting claw 81 is housed in a space sandwiched between the first virtual surface P1 including the first surface 61 and the second virtual surface P2 including the second surface 62. The first surface 61 and the second surface 62 are connected by a third surface 63. The mounting claw 81 is located in the vicinity of the third surface 63, that is, the strength of the side plate 60 in the thickness direction is high. As a result, the second surface 62 of the side plate 60 prevents contact between the mounting claws 81 of the cover 80 and the internal parts, so that damage to the mounting claws due to interference with the internal parts is prevented. Further, since the cover 80 is made of resin, the attachment claw 81 has elasticity and is prevented from being damaged when attached to the side plate 60.

(2)
In the heat pump unit 2, the soundproof material 90 that covers the components in the casing 50 is pressed against the second surface 62. Since the third surface 63 enhances the resistance against deformation in the thickness direction of the side plate 60, the soundproof material 90 is allowed to be pressed against the side plate 60, and the soundproof material 90 and the side plate 60 are in close contact with each other and the soundproof material 90 and the internal components. Adhesion with the is secured, and the soundproofing effect is increased.

(3)
In the heat pump unit 2, the pipe joint mounting plate 71 has a protrusion 72. The attachment claw 81 of the cover 80 is housed in a space sandwiched between the first virtual surface P1 and the third virtual surface P3 including the tip of the protrusion 72. As a result, when the soundproofing material 90 is disposed in the casing 50, the protrusion 72 of the pipe joint mounting plate 71 prevents the attachment claw 81 of the cover 80 from contacting the soundproofing material 90. Damage to the mounting claw 81 is prevented.

<Other embodiments>
The material of the cover 80 may be made of a material that easily burns. When the cover 80 is made of resin, for example, general PP (polypropylene) or weather-resistant PP (polypropylene), which is a flammable material, is selected. As a result, when the outdoor unit of the refrigeration apparatus such as the heat pump unit 2 is damaged by arson or fire, it does not spread to the inside of the casing even if the cover is burnt out. . In addition, since the cover is made of a material that easily burns, an additive for increasing the flame retardance is not necessary, so that the cost is reduced. Furthermore, since an additive that increases flame retardancy is not used, strength reduction is suppressed, and breakage and the like are less likely to occur.

  As described above, according to the present invention, it is possible to prevent parts from coming into contact with the attachment claws and damage them, so that it is useful for an attachment structure in which the attachment claws are hooked and held in the attachment holes.
