The housing according to the prior art and the housing according to the first embodiment of the present invention were subjected to a waterproof test according to JIS C0920-1993 “Waterproof test for electric machine equipment and protection class against intrusion of solid matter” standard. Was. 11 to 15, a transcript 14Y-JET0208 and a test report 02TR-Y1107 according to the protection class 4 (anti-eyelash) standard are attached to the housing according to the conventional technology. 16 to FIG. 20, a transcript 14Y-JET0210 and a test report 02TR-Y1113 according to the protection class 5 (jetproof type) standard are attached to the housing according to the present invention.
[0016]
With respect to the housing according to the prior art, a water spouting rate of 10 L / min and a water pressure of 50 kPa were obtained using a dropper over the entire range from the height of 300 mm above the housing to 180 degrees on both sides from the vertical direction. When water was sprayed on the housing for 5 minutes, it was confirmed that there was no water in the housing, and it was proved that it conformed to the protection class 4 (anti-eyelash) standard.
[0017]
On the other hand, in the case according to the present invention, 12.5 L / min of water is applied to the case using a nozzle having an inner diameter of 6.3 mm in all directions from a position 2.5 m from the case. When water is injected for 3 minutes, it is confirmed that there is no water in the housing, and the protection class 5 (waterproof type) having a higher waterproof function than the protection class 4 (proof type) to which the housing according to the prior art is compatible. It was proved that it conformed to the standard.
[0018]
Next, a second embodiment according to the present invention will be described with reference to FIGS. 5A and 5B are diagrams showing a second embodiment according to the present invention, wherein FIG. 5A is a front view, FIG. 5B is a right side view, and FIG. 5A and 5B are diagrams illustrating the second embodiment, in which FIG. 5A is a cross-sectional view taken along the line BB of FIG. 5B of the entire upper surface including the exhaust port portion on the ceiling surface, and FIG. It is the partial enlarged end view of (a) which showed the direction by the arrow. The description of the portions having the same configuration and function as those of the outdoor installation housing according to the first embodiment shown in FIGS. 1 to 4 will be omitted.
[0019]
In the second embodiment according to the present invention, as shown in FIGS. 5 and 6, the upper part of the right sunshade plate 7c and the left sunshade plate 7a attached to the left and right side surfaces of the housing 1, and the front door surface The left side windshield 7a1 and the front door windshield 7b1 that cover the step difference h from the reference plane B relating to the ceiling surface 5 of the housing 1 to the upper surface J of the ceiling panel 8 are provided above the front door shade 7b attached to the housing 1. The right side windshield 7c1 is disposed so as to have a relationship within the inclination θ with respect to the sunshade 7 (see FIG. 6B). Is the angle of the windshield 7x1 with respect to the vertical direction that can be set within a range where the windshield 7x1 contacts the ceiling plate 8 and does not impair air permeability. That is, as shown in FIG. 6 (b), the left side windshield 7a1 is disposed with respect to the left side sunshade 7a so as to have a relationship within the inclination θ within the housing 1 in the inward direction. The width L 'of the gap between the left side windshield 7a1 on the upper surface J and the folded back plate 13 and the width of the gap between the left side shade 7a and the end of the ceiling surface 5 on the reference plane B L has a relationship of L> L ′. By taking the relationship of L> L ′, the total amount of wind and rain entering the inside of the housing 1 can be reduced by reducing the width L ′ of the gap existing between the left side windshield 7a1 and the folded back plate 13. Is possible. Further, since the left side windshield 7a1 is arranged so as to have a relationship within the inclination θ within the housing 1 with respect to the left side sunshade 7a, the incident angle increases by the inclination θ. However, since the reflection angle also increases, the energy of the wind and rain entering the inside of the housing 1 is dispersed, and the penetration of the wind and rain into the inside of the housing 1 is further prevented.
[0020]
