  As described above, the service panel can improve the workability at the time of attachment and detachment as compared with the service panel using the claw fixing method as the fixing method. However, in the case of the claw fixing method, the locking hole must be made larger than the locking claw, so that rainwater may enter from the gap of the locking hole after the service panel is attached. In particular, the machine room is in communication with the heat exchanger room and has negative pressure due to the suction action of the fan, so rainwater tends to enter from the locking hole, which is on the electrical equipment that dislikes water entry. It was feared that the scattering would cause troubles such as failure and control failure.

  Therefore, in order to prevent water from entering through the claw's locking holes, waterproofing measures have been taken for each hole, such as by sticking insulation to close the gap, but as the number of holes increases, the work man-hours and costs are increased. In addition to the increase in water resistance, waterproofing measures by attaching insulation cannot be a permanent measure due to the ease of peeling or deterioration of the adhesive surface, and water infiltration is proportional to the increase in the number of holes. There were issues such as increased risk.

  The present invention has been made in view of such circumstances, and in a service panel having a claw fixing method, even if rainwater enters from a locking hole, it can be processed without affecting internal components. It aims at providing the outdoor unit of the air conditioner which gave the permanent waterproof measure which can simplify and reduce cost.

  Furthermore, in this embodiment, the service panel 10 provided in the opening part 9 between the front panel 5 and the rear panel 6 of the outdoor unit 1 is detachably installed by a claw fixing method. For this reason, there is a possibility that rainwater may enter the machine room side through the gaps of the lock holes 12 where the lock claws 13 are locked, and the rainwater is scattered on the control box and the electrical components disposed in the machine room. there's a possibility that. In order to prevent this, the following configuration is adopted.

  The locking holes 12 are provided at three locations in the vertical direction with respect to the side edge 6B of the opening side edge 6A of the rear panel 6. An eaves member 16 extending in the vertical direction is provided so as to cover the back surface side of the plurality of locking holes 12, and fixed to the overlapping portion 6C of the rear panel 6 with screws 17 at a plurality of vertical positions. ing. The gutter member 16 collects rainwater that has entered from the respective locking holes 12 so that it does not scatter into the machine room as it is, flows down along the gutter member 16, and at least on the internal parts that dislike water intrusion. Drainage is possible at a lower position where there is no possibility of scattering.

  The eaves member 16 is formed by forming a steel plate into an L shape, or a resin material is formed into an L shape plate, and covers the back side of the plurality of locking holes 12 with an L-shaped short side 16A. The long side 16B is overlapped with the overlapping portion 6C of the rear panel 6 and fixed with screws. Accordingly, a space 18 having an appropriate size and shape shielded from the machine room is formed on the back surface side of the plurality of locking holes 12, and the flow path through which rainwater entering the space 18 flows downward. It is said.

  In the above description, the example in which the flange member 16 is provided on the back surface side of the locking hole 12 of the rear panel 6 has been described. However, the same applies to the back surface side of the locking hole (not shown) on the front panel 5 side as necessary. Needless to say, the eaves member may be provided in the case.

With the configuration described above, according to the present embodiment, the following operational effects can be obtained.
The service panel 10 of the outdoor unit 1 is used to perform maintenance and inspection services for outdoor equipment such as a control box disposed on the machine room side in the housing 8 by attaching and detaching the service panel 10. By adopting this method, serviceability is improved by minimizing the number of screwing points.

  As described above, when the service panel 10 is installed in the claw fixing method, the gap between the rear panel 6 and the locking hole 12 on the front panel 5 side where the locking claw 13 on the service panel 10 side is locked in rainy weather or the like. There is a risk of rainwater entering. In particular, the machine room has a negative pressure due to the suction action of the outdoor fan provided on the heat exchanger room side, so that rainwater traveling on the panel surface is sucked into the interior from the locking hole 12 and easily enters. Become.

  However, in the present embodiment, the rear panel 6 or the front panel 5 opening side edges 6A, 5A provided with the plurality of locking holes 12 are arranged in the vertical direction to cover the back surfaces of the plurality of locking holes 12 on the back surface side. In the lower position where the intrusion water from the locking hole 12 flows down along the saddle member 16 and at least is not scattered by internal parts such as electrical parts that dislike water intrusion, The water is drained inside or outside the housing 8.

  For this reason, it is possible to prevent a situation in which rainwater that has entered from the locking hole 12 is scattered to an electrical component or the like that dislikes the entry of water, and to eliminate occurrence of troubles such as malfunctions and poor control due to water intrusion. it can. Further, as a measure against waterproofing, it is only necessary to provide one flange member 16 extending in the vertical direction on the back side so as to straddle the plurality of upper and lower locking holes 12, simplifying the waterproof structure and facilitating the assembly work. The cost can be reduced and permanent waterproofing measures can be taken.

  Further, since the eaves member 16 is a member that forms a space 18 having an arbitrary shape and size capable of allowing the ingress water to flow down on the back side of the locking hole 12, the plurality of locking holes 12 The infiltrated rain water can flow downward through a space 18 having an arbitrary shape and size formed by the gutter member 16, and can be drained from the lower end to the inside or outside of the housing 8. In addition, the shape and size of the space 18 formed by the gutter member 16 may be simple and small enough to allow a small amount of rainwater entering from the plurality of locking holes 12 to flow down. The configuration can be simplified and the cost can be reduced.

  Furthermore, in this embodiment, the eaves member 16 is made of a steel plate or a resin plate. For this reason, there is no concern that the adhesive surface peels off or deteriorates over time, as in the case where the gap of the locking hole 12 is closed by pasting insulation, and the permanent waterproofing measure can do. Therefore, it is possible to eliminate an increase in the risk of water ingress with the passage of time.

[Other embodiments]
