The first hole 154a is configured as a fastening member passing-through portion through which the head portion 32 and the body portion 34 of the fastening member 30 fastened to the housing 12 can pass. The first hole 154a is formed as a circular hole surrounded by the C-shaped first arc portion 154a1, and the diameter of the first hole 154a is larger than the maximum diameter of the head 32 of the fastening member 30. The shape of the first hole portion 154a may be any shape as long as it can pass through the head portion 32 and the body portion 34 of the fastening member 30, and may be, for example, an elliptical hole or a polygonal hole.
The second hole 154b is configured as a fastener locking portion through which the body portion 34 of the fastener 30 can pass and which can lock the head portion 32 of the fastener 30. The second hole 154b is configured as a hole extending in a direction in which the linear boundary 17 extends, that is, in a direction parallel to the guide surface portion 16. For example, as shown in fig. 5, the second hole 154b may be formed in a region surrounded by the first straight line portion 154b1, the second straight line portion 154b2, and the second arc portion 154b 3. The first straight line portion 154b1 may be configured to extend from one end of the C-shaped first arc portion 154a1 in a direction parallel to the guide surface portion 16. The second linear portion 154b2 may be configured to extend from the other end of the C-shaped first arc portion 154a1 in a direction parallel to the guide surface portion 16. The second arc portion 154b3 may be configured to extend in a semicircular shape between the tip of the first linear portion 154b1 and the second linear portion 154b 2. That is, the second hole 154b is formed as a U-shaped hole provided in a region surrounded by the first straight line portion 154b1, the second straight line portion 154b2, and the second arc portion 154b 3. The second hole 154b is configured to: the width between the first linear portion 154b1 and the second linear portion 154b2 is greater than the maximum diameter of the torso portion 34 of the securing member 30 and less than the maximum diameter of the head portion 32 of the securing member 30.

The third circular arc portion 154c3 may be configured to extend in a semicircular shape between the distal end of the third linear portion 154c1 and the fourth linear portion 154c 2. That is, the third hole 154c is formed as a U-shaped hole provided in a region surrounded by the third straight line portion 154c1, the fourth straight line portion 154c2, and the third arc portion 154c3, and the second hole 154b and the third hole 154c are formed as L-shaped fastener locking portions. The third hole portion 154c is configured such that the width between the third linear portion 154c1 and the fourth linear portion 154c2 is larger than the maximum diameter of the trunk portion 34 of the fastening member 30 and smaller than the maximum diameter of the head portion 32 of the fastening member 30.
The shape of the third hole portion 154c may be other shapes as long as it is a hole extending from the second hole portion 154b in a direction away from the guide surface portion 16, and is a shape through which the head portion 32 of the fastening member 30 can pass, and is a shape to which the head portion 32 of the fastening member 30 can be locked. For example, the third hole portion 154c may be a circular or elliptical hole, or may be a polygonal hole.
In fig. 5, the second hole portion 154b and the third hole portion 154c are formed as L-shaped fastener engagement portions, but the second hole portion 154b and the third hole portion 154c may be formed as T-shaped fastener engagement portions. That is, the third hole portion 154c may be configured to extend from the center position of the second linear portion 154b2 of the second hole portion 154b in a direction away from the guide surface portion 16. In fig. 5, the third hole 154c is configured to extend in the vertical direction with respect to the second hole 154b, but the third hole 154c may extend in a direction away from the guide surface portion 16, and may be configured to extend in a direction other than the vertical direction depending on the form of the air conditioner 100.
The fastening member attachment portion 154 may have only the first hole portion 154a and the second hole portion 154b, and may not have the third hole portion 154 c.
Next, a method of attaching the case 12 of the electrical box 10 to the lid 14 will be described with reference to fig. 6 and 7. Fig. 6 is a perspective view schematically showing the electric box 10 of the air conditioner 100 according to embodiment 1 before the cover 14 is attached to the casing 12. Fig. 7 is a perspective view schematically showing the electric box 10 in the air conditioner 100 according to embodiment 1 after the cover 14 is attached to the casing 12.
As shown in fig. 6, before the cover 14 is attached to the case 12, the plurality of fastening members 30 are engaged with the screw holes 13a of the attachment member 13 with a gap therebetween so that the head portions 32 of the fastening members 30 do not contact the attachment member 13. The cover 14 is disposed such that the guide surface portion 16 covers the flat surface 12b of the case 12, and then the head portion 32 of the fastening member 30 penetrates the first hole portion 154a of each fastening member attachment portion 154 provided on the closed surface portion 15. As shown in fig. 6, when the flat surface 12b of the housing 12 is disposed facing upward, the guide surface portion 16 is also disposed facing upward.
When the head portion 32 of the fastening member 30 is inserted through the first hole portion 154a, the guide surface portion 16 covering the flat surface 12b abuts against the lid body 14, and the longitudinal movement of the lid body 14 is suppressed. Therefore, the maintenance inspector of the air conditioner 100 can easily pass the head portion 32 of the fastening member 30 through the first hole portion 154a by positioning the guide surface portion 16 in the longitudinal direction even during high-altitude work.
Next, as shown in fig. 7, the cover 14 is moved in the lateral direction so that the head portion 32 of the fastening member 30 is positioned from the first hole portion 154a of the fastening member mounting portion 154 to the second hole portion 154b of the fastening member mounting portion 154. Then, the head portion 32 of the fastening member 30 is brought into contact with the lid 14 at the position of the second hole portion 154b, and the lid 14 is fixed to the case 12.
When the cover 14 moves in the lateral direction, the guide surface portion 16 of the cover 14 can be slid with respect to the flat surface 12b of the housing 12, and thus the movement from the first hole portion 154a to the second hole portion 154b of the fastening member 30 can be smoothly performed. Therefore, by positioning the guide surface portion 16 in the lateral direction, the fastening member 30 can be prevented from being caught when the lid 14 moves. Further, since the guide surface portion 16 suppresses the longitudinal movement of the lid 14, it is possible to prevent the lid 14 from falling down during high-altitude work.
Fig. 8 is a perspective view schematically showing the electric equipment box 10 in which the cover 14 is attached to the casing 12 upside down in the air conditioner 100 according to embodiment 1. As shown in fig. 8, the fastening member attachment portion 154 of the closing surface portion 15 of the lid 14 has a configuration having the third hole portion 154c, and thus the lid 14 can be attached to the case 12 upside down.
According to this configuration, even when a maintenance inspector of the air conditioner 100 temporarily interrupts the wiring work of the electric components, the opening surface 12a of the housing 12 can be easily temporarily closed by pushing the guide surface portion 16 upward. Therefore, the efficiency of the maintenance and inspection work of the air conditioner 100 can be improved, and the safety during the maintenance and inspection work can be ensured.
In the example of fig. 8, the display unit 19 can display the arrangement diagram of the electrical components mounted on the substrate 20 rotated 180 degrees in parallel with the planar portion 152 in the same manner as the arrangement of the electrical components viewed from the opening surface 12a of the housing 12.
