Description

  The present invention relates to a ventilation structure in an outdoor panel that is disposed outdoors and requires countermeasures against rainwater.

  In an outdoor panel such as a control panel installed outdoors, the heat generated from the electrical component, etc. from the viewpoint of preventing thermal damage to the electrical component stored in the panel and ensuring its operational reliability. It is necessary to ventilate the inside of the panel by discharging the air in the panel (hot air) heated by the heat absorption from the outside of the panel to the outside of the panel and introducing fresh air into the panel from the outside. At the same time, it is also necessary to take measures to prevent rainwater from entering the panel.

  From this point of view, various outdoor panel ventilation structures that have taken measures to prevent rainwater ingress have been proposed (see Patent Documents 1 to 3).

JP-A-63-3603 Japanese Utility Model Publication No. 60-18609 Japanese Utility Model Publication No. 62-54504

  Patent Document 1 discloses that a ventilation fan is arranged inside an outdoor cubicle, while a communication port provided with a self-weighted blade lattice is formed on an upper side wall of the cubicle, and the communication port is formed outside the cubicle. A roofing material is provided so as to cover, and an exhaust port is opened downward at the lower end of the roofing material.

  However, this system has a problem that a ventilation fan is provided as a ventilation means, and the structure for measures against rainwater is large and complicated, resulting in an increase in cost.

  Although the thing of patent document 2 employ | adopted the ventilation system by a natural convection, although a certain amount of cost reduction is achieved, since the exhaust port is provided below the ceiling surface which consists of the board | plate material extended in a horizontal direction, Hot air stays in the upper part of the mouth, and it is difficult to say that ventilation is sufficient.

  Also, a ventilation duct is provided on the inner side of the box body, and rainwater that enters from the ventilation hole provided on the side wall of the box body is blocked by the ventilation duct, that is, rainwater enters from the ventilation hole to the inside. In view of the possibility of an electric shock or the like, it is difficult to say that the configuration is preferable.

  The thing of patent document 3 employ | adopts the ventilation system by a natural convection, Although it can comprise the board | plate material which inclines and extends a ceiling surface, and the residence of hot air can be promoted by this ceiling surface, an exhaust port is the said ceiling surface Since it is provided further downward, hot air stays in the upper part of the exhaust port, and it is difficult to say that ventilation is sufficient.

  In addition, a box having a large number of small holes is arranged on the outer surface side of the vent so as to cover it, and hot air flowing out from the vent is released to the outside air through the numerous small holes of the box. However, rainwater intrusion prevention measures can be realized by reducing the diameter of the small hole, but such a configuration, on the other hand, becomes a factor that hinders the release of hot air, ventilation and rainwater intrusion prevention measures However, there was still a problem in terms of both.

Accordingly , the present invention has been made for the purpose of realizing a ventilation structure having both high ventilation performance and rainwater intrusion prevention performance with a simple and inexpensive configuration.

In the present invention, as a specific means for solving such problems, it adopts the following configuration.

By arranging so as to extend to the rear, the concave cutout portion cannot face through the gap from obliquely below.

For this reason, for example, even if rainwater is rolled up from below by strong winds and directly enters the gap side, the rainwater collides with the first blocking portion of the rainwater intrusion prevention material and moves to the concave notch side. Is surely blocked and flows down from the first blocking portion as it is.

And since the rain water which flowed down from this 1st prevention part side moves to the said 2nd prevention part side, and is discharged | emitted smoothly outward from this 2nd prevention part, the water drainage property becomes especially good.

(B) In the second invention of the present application, in addition to the effects described in (a) above, the following specific effects can be obtained.

That is, in the present invention, since the second blocking portion is extended downwardly from the front wall, the water drainage at the second blocking portion is improved, so that rainwater enters the panel. The prevention effect is further ensured.

(C) In the third invention of the present application, in addition to the effects described in (a) above, the following specific effects can be obtained.

That is, in the present invention, since the second blocking portion is inclined in the width direction of the back wall, the water drainage property of the second blocking portion is improved, and the rainwater penetration preventing effect into the panel is further improved. Is even more certain.

  Hereinafter, the present invention will be specifically described based on preferred embodiments.

A ground leg 26 is provided on the lower side of the bottom wall 24.

  In the panel body 2, the upper end surface 1 a is formed in an inclined surface shape that gradually rises and inclines from the front wall 22 toward the back wall 21. Furthermore, a concave notch 5 having a predetermined depth is provided at the upper end portion of the back wall 21 and extends at substantially the entire width in the width direction of the back wall 21. The bottom wall 24 is provided with a vent 25 for introducing air.

  On the other hand, the rainwater intrusion prevention material 4 described below is provided at a position directly below the edge 5 a of the concave notch 5 in the back wall 21 of the panel body 2. The rainwater intrusion prevention material 4 is formed by bending a plate material having a width direction length substantially matching the width dimension of the back wall 21 of the panel body 2. That is, the rainwater intrusion prevention material 4 is bent so that the range of about 1/3 from the upper edge of the plate material rises and tilts toward the near side, and this is used as the first prevention portion 41, and the bottom of the plate material is A range of about ３ from the edge is bent so as to be slightly inclined downward toward the front side, and this is used as the second blocking portion 42, and further between the first blocking portion 41 and the second blocking portion 42. This portion is used as a fixed portion 43.

  As shown in FIG. 2, the rainwater intrusion prevention material 4 formed in this way is lowered by a predetermined dimension from the edge 5 a of the concave notch 5 with respect to the ridgeline of the first prevention part 41 and the fixing part 43. The fixing portion 43 is attached and fixed to the back wall 21 in a state of being substantially parallel to the edge portion at the side position, thereby being attached to the panel body 2 side.

B: Roof body 3
The roof body 3 is arranged so as to cover the upper surface opening of the panel main body 2 from the upper side, and is constituted by a rectangular flat body larger than the front and rear dimensions and the width dimension of the panel main body 2 by a predetermined dimension. A ceiling wall 31, a rear vertical wall 32 extending downward from the entire width direction of the front edge of the ceiling wall 31, and a front vertical wall 34 extending downward from the entire width direction of the front edge of the ceiling wall 31. And a pair of left and right side vertical walls 33 that connect the rear vertical wall 32 and the front vertical wall 34.

  Here, by setting the height dimension of the rear vertical wall 32 larger than the height dimension of the front vertical wall 34 by a predetermined dimension, the ceiling wall 31 moves from the front vertical wall 34 side to the rear vertical wall 32 side. As it heads toward, it is going to tilt up. Specifically, the inclination angle of the ceiling wall 31 with respect to the lower edge of the side vertical wall 33 substantially corresponds to the inclination angle of the upper end surface of the panel body 2.

C: Assembly of the panel body 2 and the roof body 3 Covering the roof body 3 from the upper side of the panel body 2 so as to cover the upper surface opening of the panel body 2 and fixing them together with appropriate connecting means The above-mentioned outdoor panel 1 is configured. In the outdoor panel 1, as shown in FIG. 2, the ceiling wall 31 of the roof body 3 is placed on the inclined upper end surface of the panel body 2, and the panel body 2 is placed by the ceiling wall 31. The upper end of the concave notch 5 on the side is closed.

  Further, the rear vertical wall 32 of the roof body 3 extends rearward from the rear wall 21 of the panel body 2 by a predetermined length, and the rear end of the ceiling wall 31, the rear vertical wall 32, and the panel body. In the inner space 36 surrounded by the upper three of the two rear walls 21, the concave notch 5 on the panel body 2 side and the first blocking portion 41 of the rainwater intrusion blocking material 4 face each other. The internal space 6 of the outdoor panel 1 communicates with the inner space 36 through the concave notch 5.

  Furthermore, the first blocking portion 41 of the rainwater intrusion prevention material 4 faces obliquely forward and downward through the gap 7 between the lower end of the rear vertical wall 32 of the roof body 3 and the rainwater intrusion prevention material 4, Due to the presence of the first blocking portion 41, the concave notch 5 cannot be seen from obliquely forward and downward.

D: Explanation of operational effects With the configuration as described above, in the outdoor panel 1 of this embodiment, as will be described below, the ventilation function of the in-board space 6 and the in-board space 6 are Both rainwater intrusion prevention action is achieved.

D-1: Ventilation effect of the internal space 6;
Outside air is introduced into the inner space 6 from a vent 25 provided in the bottom wall 24 of the main body 2.

  On the other hand, the interior of the internal space 6 is heated by receiving heat from various electrical components housed therein or solar heat entering through the outer wall of the outdoor panel 1. The generated hot air is discharged to the outside by natural convection. Ventilation of the internal space 6 is performed by introducing fresh air into the internal space 6 and discharging hot air from the internal space 6 to the outside.

  In this case, in the outdoor panel 1 of this embodiment, the roof body 3 is inclined upward from the front wall 22 of the panel body 2 toward the rear wall 21 and the rear end portion is further rearward from the rear wall 21. A ceiling wall 31 extending to the side and a rear vertical wall 32 extending downward continuously from the rear end of the ceiling wall 31, while the upper end of the back wall 21 is open to the edge of the rear wall 21. Since the concave notch 5 extending in the width direction of the back wall 21 is provided, the inner surface of the ceiling wall 31 of the roof body 3 passes through the concave notch 5 from the inner side of the panel body 2 to the rear vertical wall 32 side. It will be continuous in the ascending state.

  As a result, the hot air heated by the heat generated from the electrical components in the outdoor panel 1 and the heat absorbed from the outside of the panel rises to the inner surface side of the ceiling wall 31 of the roof body 3 by natural convection, and then flows in FIG. As indicated by the line A, the roof body 3 moves toward the concave notch 5 along the inner surface of the ceiling wall 31 that is inclined upward, and further moves toward the rear vertical wall 32 through the concave notch 5. To the inner space 36 side.

  In this case, since the concave notch 5 serving as a hot air passage is formed up to the inner surface of the ceiling wall 31 of the roof body 3, the flow of hot air flowing out from the inner space 6 side is not obstructed. Therefore, the hot air in the internal space 6 is smoothly discharged along the inner surface of the ceiling wall 31 and through the concave notch 5 to the inner space 36 side. Then, the hot air that has flowed into the inner space 36 is discharged to the outside from the space 7 below the inner space 36.

  That is, in the outdoor panel 1, the ceiling wall 31 of the roof body 3 is inclined, the concave notch 5 is provided in the back wall 21 of the panel body 2, and the concave notch 5 is formed on the inner surface of the ceiling wall 31. High ventilation performance can be realized by a simple and inexpensive configuration that expands to a maximum.

D-2: Rainwater Invasion Preventing Action In the outdoor panel 1 of this embodiment, the concave notch 5 is formed in the upper end portion of the back wall 21 of the panel body 2 so as to extend over substantially the entire width of the back wall 21. Therefore, it is necessary to accurately prevent the intrusion of rainwater from the large opening. Therefore, in this embodiment, the rainwater intrusion prevention material 4 is provided on the back wall 21 of the panel body 2 in this embodiment. Yes.

  That is, the rainwater intrusion prevention material 4 is arranged such that the first prevention portion 41 extends obliquely upward from the position immediately below the edge portion 5a of the concave notch 5, so that the concave notch 5 Cannot face through the gap 7 from obliquely below.

  For this reason, for example, even if rainwater directly enters the gap 7 side so that the rainwater is wound up from below by strong wind, the rainwater is first blocked by the rainwater penetration preventing material 4 as indicated by the streamline W1. It collides with 41 and is prevented from entering the concave notch 5 and flows down from the first blocking portion 41 as it is.

  The rainwater flowing down from the first blocking portion 41 side moves to the second blocking portion 42 side as indicated by the streamline W2, and in this case, the second blocking portion 42 is slightly lowered toward the front. Since it is inclined, it is discharged from the second blocking portion 42 in a smooth manner, and its water drainage is improved.

  In this embodiment, the rainwater intrusion prevention material 4 is mounted substantially horizontally along the edge of the concave notch 5, but in another embodiment of the present invention, for example, the rainwater intrusion prevention material 4 is It can also be attached to be tilted slightly to the left or right, and according to such a configuration, the water drainage at the second blocking portion 42 of the rainwater intrusion blocking material 4 is further improved.

  On the other hand, for example, rainwater that adheres to the surface of the back wall 21 of the panel main body 2 due to strong wind and then is pushed down from the bottom toward the rainwater intrusion prevention material 4 side as indicated by the streamline W3. When the second blocking portion 42 is reached, further upward movement is blocked and it falls downward.

  As a synergistic effect of the rainwater intrusion prevention action by the first prevention part 41 and the second prevention part 42, the concave notch 5 having a large opening area is formed on the back wall 21 of the evening body 2, High rainwater intrusion prevention effect can be obtained.

  As described above, the outdoor panel 1 of this embodiment has both high ventilation performance and rainwater intrusion prevention performance, and is extremely useful in practice.
