Description

  The present invention relates to an electric equipment storage box installed with an opening provided with a door facing upward.

  Some electrical equipment storage boxes are installed on the roof of a house, such as a solar power collector. If such an electric device storage box is installed upright on the roof, there is a risk that the solar panel will be shaded by the electric device storage box and power generation efficiency will be reduced. For this reason, as in Patent Document 1, the electric device storage box may be placed on the roof surface so that the opening of the box body faces upward.

  A door that covers the opening on the upper surface is attached to the box body of the electrical equipment storage box by a hinge, and the door is opened so as to be lifted upward to exchange internal equipment. As shown in FIGS. 7 and 8, in order to improve the strength of such a door 1, the side opposite to the hinge may be folded inward in a U shape to form a folded side 11. It is common. Further, the peripheral edge of the opening of the box body 1 is bent inward as shown in FIG. 8 to form the horizontal side 7, the rising side 8, and the bent side 9, and between the bent side 9 and the back surface of the door 2. The waterproof packing 13 is disposed to form a draining structure that prevents rainwater from entering.

  For this reason, there is no possibility that rainwater intrudes into the inside of the box body 1 when the door 2 is closed. However, as shown in FIG. 8, the water droplets 100 entering between the folded side 11 of the door 2 and the horizontal side 7 of the box body 1 form a water film 200 by surface tension as shown in FIG. When the door 2 is lifted and opened as described above, the water droplet 100a falls into the box body 1 and may adversely affect the internal electrical equipment. In order to avoid this problem, before opening the door 2, the operator wipes off the water droplets adhering to the outline of the box body 1, removes the water film, and then opens the door 2. However, there is a problem that the water droplet 100 accumulated in the gap may be overlooked, and it is difficult to completely wipe off the water film, and the wiping operation itself is troublesome.

Further, the closing member is characterized in that water entering between the two sides is prevented from forming a water film due to surface tension between the folded side and the horizontal side.

  The closing member may be provided on the inner side of the end of the hanging side and the horizontal side and on the outer side of the position where a water film is formed by surface tension between the folded side and the horizontal side. preferable. The closing member is preferably attached integrally to the folded side or the horizontal side, and the material of the closing member is preferably a non-water-absorbing material. Furthermore, it is preferable to provide a waterproof packing between the draining portion and the back surface of the door in order to prevent rainwater to be entrained from entering the inside of the box body. Also, an electric equipment storage box comprising a box body installed with the opening facing upward, and an upper-opening door attached to the box body with a hinge and covering the opening, the box body being , Including a draining portion composed of a horizontal side and an upright side bent at the periphery of the opening, and the door includes a hanging side at least on the side opposite to the hinge, the hanging side and the horizontal side A closing member may be provided between the two.

  The electrical equipment storage box according to the present invention is provided with a closing member at least between the hanging side of the door opposite to the hinge and the horizontal side of the box body. This prevents rainwater from entering between the folded side or the drooping side and the horizontal side, so that a water film is not formed due to surface tension in this part, or even if it is formed, the amount is small. Become. Further, by providing the inner side of the drooping side and the end of the horizontal side and outside the position where the water film is formed by the surface tension between the folded side and the horizontal side, By providing a blocking member that prevents the formation of a water film, the water droplets are in a position where they can be wiped from the outside, and the water droplets flow down along the housing. Therefore, even if the door is lifted and opened, water drops do not fall into the box body, which is safe. Further, it is possible to save the trouble of previously removing the water film with water absorbent paper or the like as in the prior art.

Preferred embodiments of the present invention are shown below.
1 to 4 are views showing a first embodiment of the present invention. In FIGS. 1 and 2, reference numeral 1 denotes a box body that houses an electric device therein, and 2 is a hinge body 3 attached to the box body. It is a door. This electrical equipment storage box is, for example, a storage box for a collector of a solar system, and is installed on the roof of a house with the opening 4 of the box body 1 facing upward, and the opening 4 is an open door. 2 covered. The door 2 can be opened upward by lifting the handle 5.

  As shown in FIG. 3 and FIG. 4, the box body 1 includes a draining portion 6 having a substantially U-shaped cross section in which the periphery of the opening 4 is bent inward. In the present embodiment, the draining portion 6 includes a horizontal side 7 parallel to the bottom surface of the box body 1, a rising side 8 extending in the vertical direction from the front end of the horizontal side 7, and a horizontal side from the front end of the rising side 8 toward the outside. It consists of a bent side 9 extending in the direction. In the state where the door 2 is closed, the upper surface of the bent side 9 is brought into close contact with the waterproof packing 13 attached to the rear surface of the door 2 to prevent rainwater from entering the box body 1. In addition, the structure of the draining part 6 is not limited to this, For example, the bending side 9 does not need to be provided. In this case, the front end of the rising side 8 may be brought into close contact with the waterproof packing 13.

  The door 2 is bent at the end of the top surface downward to form a drooping side 10, and the drooping side 10 opposite to the hinge 3, that is, the tip of the drooping side 10 to which the handle 5 is attached is the box body 1. The folded side 11 is formed by folding inwardly in parallel with the horizontal side. A closing member 12 is attached to the bottom surface of the folded side 11. The closing member 12 is in close contact with the horizontal side 7 on the handle 5 side in a state where the door 2 is closed, and closes between the folded side 11 and the horizontal side 7. Thereby, it is possible to prevent water that has entered between the folded side 11 of the door 2 and the horizontal side 7 of the box body 1 from forming a water film due to surface tension. There is no need to wipe off the gaps in the electrical equipment storage box, and only the outline of the electrical equipment storage box needs to be wiped out. Also, even if the door 2 is lifted up without wiping, water drops will fall along the exterior of the electrical equipment storage box. No raindrops will drop from 11 and it is safe. The mounting position of the closing member 12 will be described in detail later.

  The material of the closing member 12 is preferably a non-water-absorbing material. For example, a non-water-absorbing packing, a foamed rubber formed with a film, or a packing in which the foamed rubber is hollow is used. If a material having high water absorption is used, the closing member 12 itself absorbs rainwater. Therefore, when the door 2 is lifted, the closing member 12 adsorbs water droplets and carries it to the box body 1, which does not solve the problem. If the material has low water absorption, there is no worry of dripping rain water. The closing member also serves as a door stop that softens the impact when the door 2 is opened and closed.

  In the present embodiment, a waterproof packing 13 is attached to the periphery of the back surface of the door 2. The waterproof packing 13 is in close contact with the bent side 9 of the box body 1 when the door 2 is closed, and prevents rainwater from entering the inside of the box body 1. In the present embodiment, the waterproof packing 13 is made of a material such as EPDM. Thus, by providing both the closing member 12 and the waterproof packing 13, it is possible to reliably prevent the intrusion of rainwater even when the door 2 is opened or closed.

  In the second embodiment shown in FIG. 5 and the third embodiment shown in FIG. 6, the closing member 12 of the first embodiment is formed on the box body 1 side. In these cases, the closing member 12 is formed at a position in close contact with the folded side 11 of the door 2 when the door 2 is closed. As a result, rainwater does not enter between the folded side 11 of the door 2 and the horizontal side 7 of the box body 1 as in the first embodiment. No dripping.

  Further, in the embodiment shown in FIG. 2 and FIG. 5, the box body 1 is installed horizontally, so that water droplets enter between the closing member 12 and the upright side 8 and fall to the internal device when the door 2 is opened and closed. there is a possibility. Therefore, as shown in FIG. 6, the closing member 12 is formed on three sides other than the one side to which the hinge 3 is attached to prevent water droplets from entering the inside.

  Here, the arrangement position of the closing member 12 will be described with reference to FIGS. In any case, a blocking member 12 is formed between the bent side 11 and the horizontal side 7. As a preferred form, as shown in FIG. 10, a closing member 12 is formed inside the hanging side 10 and the end 30 of the horizontal side 7, and surface tension is applied between the folded side 11 and the horizontal side. The closing member 12 is formed on the outer side that is closer to the end 30 than the position where the formed water film 200 is maintained.

  As shown in FIGS. 11 and 12, if the closing member 12 is formed on the inner side of the end portion 30 and formed on the tip side of the folded side 11, the water droplet 100 remains attached to the folded side 11 and finally. The water droplet 100 is maintained by the surface tension between the folded side 11 and the horizontal side 7, and the water film 200 is formed. Further, as shown in FIG. 13, the water film 200 is formed on the folded side 11, the horizontal side 7, and the closing member 12 by surface tension. That is, as shown in FIGS. 11 to 13, when the horizontal side 7 and the folded side 11 that store the water droplet 100 are formed on the end 30 side of the closing member 12, the horizontal side 7 is opened when the door 2 is opened. There is a risk that the water film 200 is formed due to the surface tension of the water droplet 100 maintained on the folded side 11. In this case, the water droplet 100 is lifted when the door 2 is opened, and the water droplet 100 drops on the box body 1. There is a fear.

  In the case of the arrangement as shown in FIG. 10, the closing member 12 is formed on the end 30 side between the horizontal side 7 and the folded side 11 to prevent the water film 200 from being formed due to surface tension. Further, since the closing member 12 is provided inside the end portion 30 and outside the position where the water film 200 is formed so that the water film 200 is not formed, when the door 2 is opened, the water droplet 100 is formed in the box body 1. There is no danger of dripping. In addition, when the closing member 12 is formed at this position, even when the water droplet 100 becomes a large water film 200 due to the surface tension due to the folded side 11, the horizontal side 7, and the closing side 12, it flows down by its own weight. The risk of opening and closing the door 2 with the water droplets 100 adhering to the door 2 side is small. Therefore, the structure of FIG. 10 in which the landscape is good and the water droplet 100 is not maintained on the closing member 12 is desirable with less risk of the water droplet 100 falling.

  The water film 200 formed by the surface tension between the horizontal side 7 and the folded side 11 is the size of the gap between the horizontal side 7 and the folded side 11 or when the side plate of the box body 1 and the horizontal side 7 are bent. In some cases, the position where the water film 200 is formed may be changed depending on the size of the curved surface, but the closing member 12 is provided inside the end portion 30 and outside the position where the water film 200 is formed. It is desirable to form so that 200 is not formed. Note that the water film 200 may not be formed depending on the size of the gap between the horizontal side 7 and the folded side 11, but even in that case, the water droplet 100 is prevented from dropping on the box body 1 when the door 2 is opened. For this purpose, it is desirable to form the closing member 12 so that at least the water droplet 100 that causes the surface tension is not exposed to the horizontal plane 7 or the folded side 11.

  Moreover, about FIG. 14, although the closing member 12 protrudes from the edge part 30, and forms, when the door 2 is closed, the scenery is bad and the closing member 12 is attached to the horizontal side 7. Since there is a possibility that the water droplet 100 is maintained on the closing member 12, the embodiment of FIG. 10 is preferable.

  FIGS. 15 and 16 are formed by integrally forming the closing member 12 on the folded side 11 and the horizontal side 7 via the attachment surface 12a, respectively. Even in such a case, it is desirable to form the closing member 12 inside the end portion 30. Further, when the closing member 12 is formed on the folded side 11 as shown in FIG. 15, the water droplet 100 is positioned between the horizontal side 7 and the closing member 12 outside the position where water stays due to surface tension. is there. Similarly, when the closing member 12 is formed on the horizontal side 7 as shown in FIG. 16, the water droplet 100 is positioned between the folded side 11 and the closing member 12 outside the position where water is stored by surface tension. It is. Thus, by positioning the closing member 12, the water droplet 100 does not accumulate on the folded-back side 11 or the horizontal side 7 and the water film 200 is not formed by the surface tension. Therefore, even when the door 2 is opened, It can prevent falling.

  As described above, the electrical equipment storage box according to the present invention is a closing member between the folded side 11 of the door 2 and the horizontal side 7 of the box body 1 or between the hanging side 10 and the horizontal side 7. Since 12 is provided, rainwater does not collect between the drooping side 10 or the folded side 11 and the horizontal side 7, and rainwater drops do not fall from the folded side 11 even when the door 2 is lifted. As a result, it is possible to prevent a failure of the internal device due to a drop of water droplets, and it is possible to save the trouble of removing the water film in advance with water-absorbing paper or the like.
