Description

  The present invention relates to an outdoor installation type device that is exposed to rainwater such as an electric water heater installed outdoors, a private generator such as a fuel cell, and a power supply facility such as a cubicle.

  For example, FIG. 9 shows an external structure of a rectangular tube type electric water heater that is a kind of conventional outdoor-installed equipment.

  The external appearance of this rectangular tube-shaped electric water heater is as follows. A shallow rectangular tube-shaped upper cover 2 is put on the upper opening of the container 1 facing outward, which is a vertically long rectangular tube, and the upper cover 2 is covered with a plurality of screws 3. It was the structure fixed to the container 1. The rectangular tube-shaped container 1 has a rectangular tube shape with a front surface 1a, left and right side surfaces 1b, and a rear surface, and has a structure in which an upper side is opened and a bottom portion is closed on a bottom surface. In such a rectangular tube-shaped container 1, one or a plurality of cylindrical inner containers (not shown) are accommodated and heated with an electric heater containing the water in the inner container to supply hot water. To get. An operation / display box 4 for controlling the electric heater or the like to set the temperature or displaying the temperature is installed on the upper side of the front surface 1 a of the container 1. The upper lid 2 has a structure in which a rectangular tube-shaped fitting tube portion 2b having a short vertical dimension is provided to project downward around a rectangular upper surface plate 2a, and holes are provided at a plurality of locations on the fitting tube portion 2b. These holes are fixed to the container 1 through screws 3.

  However, in the electric water heater that is an outdoor installation type device having such a structure, when it is installed outdoors and it rains, the rainwater on the upper surface plate 2a that forms the quadrilateral of the upper lid 2 is because the upper surface plate 2a is horizontal. It flows down from the four sides of the upper surface plate 2a to the peripheral wall of the container 1. Since dust and the like are accumulated on the upper surface plate 2a, the dust and the like also flow together, and when the weather is fine and dry, the dirt 5 adheres to the peripheral wall of the container 1. If this contamination increases over the years, the contamination 5 on the front surface 1a of the peripheral wall of the container 1 provided with the operation / display box 4 and the like becomes quite conspicuous, and this is to be improved in order to deteriorate the appearance of the device. There is a request.

  In the present invention, the front surface 1a of the container 1 is a surface on which the operation / display box 4 and the like are provided and becomes the front surface of the container 1, and faces a passage or the like through which a user of the device or a third party passes. It is a surface to be installed.

  As one structure satisfying this requirement, as shown in FIG. 10, it is conceivable to incline the upper surface plate 2a of the upper lid 2 so that its front portion is raised and its rear portion is lowered.

  However, with such a structure, the fitting cylinder part 2b has a tapered structure in which the front part has a long front part and a rear part becomes short, and when the top cover 2 is put on the container 1, the fitting dimension with respect to the container 1 is the front part. However, the hole 6 of the fitting cylinder portion 2b does not match the hole of the container 1 because it is deeper at the rear and shallower at the rear. For this reason, another worker supports the upper lid 2 so that the hole 6 of the fitting cylinder part 2b matches the hole of the container 1, and in this state, the screw 3 is inserted into the hole of the container 1 from the hole 6 of the fitting cylinder part 2b. There is a problem that one worker cannot work because it is necessary to fix it through.

Further, the upper surface 2a of the upper lid 2 is U-shaped when viewed from the upper surface of the upper surface plate 2a so that drainage can be performed only on the rear surface side opposite to the front surface 1a of the container 1, and the open side thereof is There has been proposed an electric water heater provided with a groove toward the rear side of the container 1 (see, for example, Patent Document 1).
JP 2005-114269 A

  However, the electric water heater provided with a U-shaped groove on the upper surface plate 2a of the upper lid 2 when viewed from the upper surface of the upper surface plate 2a has a fitting dimension with respect to the container 1 when the upper lid 2 is covered with the container 1. Although the inconvenience differs depending on whether it is deep in the part and shallow in the rear part, the rain water that has fallen on the upper surface plate 2a is drained only on the rear surface of the container 1. Therefore, if such a state continues for a long time, the rear surface of the container 1 There is a problem that corrodes. Further, when dust or the like accumulates and the groove of the upper surface plate 2a is clogged, not only the drainage effect cannot be obtained, but also rainwater accumulates in the groove and promotes corrosion of the upper surface plate 2a.

  The object of the present invention is to prevent rainwater from flowing down from the upper lid to the front surface of the container. One worker can fix the rainwater on the container of the upper lid, and rainwater that has fallen on the top plate is only on the rear surface of the container. An object of the present invention is to provide an outdoor installation type device that can prevent drainage.

  Another object of the present invention is a structure capable of satisfactorily preventing rainwater from flowing down from the upper lid to the front surface of the container and the front side of the container, and can be fixed to the container of the upper lid by one worker. An object of the present invention is to provide an outdoor installation type device capable of preventing rainwater falling on a face plate from being drained only to the rear surface of the container.

  Another object of the present invention is to provide an outdoor installation type device in which drainage does not deteriorate even when dust or the like accumulates on the upper part of the upper lid.

  Another object of the present invention is to provide an outdoor installation type device that allows rainwater to flow down from the upper lid along the rear side of the container.

  Another object of the present invention is to provide an outdoor installation type device that can reinforce the mechanical strength of the upper lid.

  Another object of the present invention is to provide an outdoor installation type apparatus in which the present invention can be applied to a container having a rectangular tube shape and a top cover having a rectangular shape when viewed from above.

  Another object of the present invention is to provide an outdoor installation type apparatus in which the present invention can be applied to a cylindrical container and a top cover having a circular shape when viewed from above.

  The configuration of the present invention that achieves the above object will be described as follows.

  According to the present invention, an upper lid fixed over a cylindrical container that faces the outside is provided with an upper surface plate that closes the upper opening of the container, and is integrally provided around the upper cover so as to protrude downward and fit into the upper part of the container. An outdoor installation type device having a structure including a fitting cylinder portion is targeted for improvement.

  In the outdoor installation type apparatus according to the present invention, the upper plate of the upper lid has a contact portion that contacts the upper end of the container and a raised portion that protrudes above the rear end of the contact portion at the front end portion corresponding to the front surface of the container. And provide. The raised portion is provided with an inclined surface in which the raised height gradually decreases toward the rear. Here, “gradually lower” includes both the case where the raised height is continuously lowered and the case where the raised height is lowered stepwise. Moreover, in this invention, an inclined surface is provided to the middle part which reaches the rear end of the upper surface board seen from the front surface of the container.

  Thus, when the upper surface plate of the upper lid is provided with a contact portion that contacts the upper end of the container, the depth at which the upper lid fits into the container is limited by the contact portion and other portions around the upper surface plate. As a result, even if another worker does not support the upper lid, it is possible for one worker to fix the upper lid to the container. In addition, a bulging portion that protrudes upward from the rear end portion of the abutting portion is provided, and an inclined surface whose bulging height gradually decreases toward the rear is formed on the bulging portion of the upper surface plate as viewed from the front of the container. If it is provided up to the middle of the rear edge, the rain water falling on the top plate will hardly flow to the front side of the container, but will flow backward along the inclined surface, preventing contamination by rain water on the front of the container. Can do. Furthermore, if this inclined surface is provided up to the middle of the top plate as viewed from the front of the container, the rain water that falls on the top plate also flows to the rear of the side of the container, causing corrosion of the rear of the container. Resistance can be improved. Moreover, since the upper surface plate of the upper lid is not provided with a groove for drainage, the groove is clogged with dust or the like, so that the drainage cannot be performed and the occurrence of problems such as promoting corrosion of the upper surface plate is avoided. be able to.

  In this case, a pair of lateral ridges may be provided that extend to the rear end side of the upper surface plate and are connected to both lateral ends of the ridge and the lateral ends of the inclined surface. Providing such a pair of side raised portions can prevent rainwater from flowing down to the front side surface located near the front surface of the container from the upper lid. Further, when the inclined surface is lowered below the upper end surfaces of the raised portions and the pair of side raised portions, the top portions of these raised portions and the pair of side raised portions serve as weirs, and rainwater is closer to the front and front of the container. It is possible to satisfactorily suppress the flow to the side surface.

  Moreover, it is preferable that the length toward the rear end side of the inclined surface is a length that allows a part of rainwater flowing down from the inclined surface to flow down along the side surface of the container as viewed from the front surface. When set to such a length, rainwater can be allowed to flow down from the upper lid along the side surface from the rear of the container. As a result, rainwater does not flow down concentratedly along the rear surface of the container, and corrosion resistance of the rear surface of the container can be improved.

  What is necessary is just to determine suitably the termination | terminus position of the rear-end part of an inclined surface. According to experiments, it has been confirmed that even when the inclined surface is terminated at a position ahead of the center portion of the upper surface plate, the contamination of the appearance of the container seen from the front side of the container is considerably improved compared to the conventional case. It was.

  In addition, if the upper surface plate is provided with reinforcing ribs that protrude upward, it is possible to prevent the mechanical strength of the upper lid from being lowered even when the protruding portion is provided. In the case of providing one reinforcing rib, one reinforcing rib is provided so as to partially cut the inclined surface between the pair of side raised portions. The reinforcing rib may be provided so as to terminate between the center position of the upper surface plate and the rear end. With such a structure, a necessary and sufficient reinforcing effect can be obtained with a small number of reinforcing ribs.

  The present invention can be applied not only to a container having a rectangular tube shape and a top cover having a square shape when viewed from the top, but also having a cylindrical shape and a contour shape when the top cover is viewed from above. Of course, it is applicable also to what is circular. When a cylindrical container is used, the shape of the raised portion when viewed from above is an arc shape. When the shape of the raised portion is set in this way, the mechanical strength of the upper lid is not significantly reduced.

  In the outdoor installation type apparatus according to the present invention, since the upper surface plate of the upper lid is provided with a contact portion that comes into contact with the upper end of the container, the upper lid fits into the container by the contact portion and other portions around the upper surface plate. The depth is limited, and one worker can fix the upper lid to the container even if another worker does not support the upper lid. In addition, a raised portion is provided which is raised above the rear end portion of the abutting portion, and an inclined surface in which the raised height gradually decreases toward the rear is formed on the raised portion of the top plate as viewed from the front of the container. Since it is provided up to the middle part to the rear end, the rain water falling on the top plate hardly flows to the front side of the container, but flows backward along the inclined surface, preventing contamination by rain water on the front of the container can do. Furthermore, if this inclined surface is provided up to the middle of the top plate as viewed from the front of the container, the rain water that falls on the top plate also flows to the rear of the side of the container, causing corrosion of the rear of the container. Resistance can be improved. Moreover, since the upper surface plate of the upper lid is not provided with a groove for drainage, the groove is clogged with dust or the like, so that the drainage cannot be performed and the occurrence of problems such as promoting corrosion of the upper surface plate is avoided. be able to.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings. Note that portions corresponding to those in FIGS. 9 and 10 described above are denoted by the same reference numerals.

  1 to 6 show a first example of the best mode of an outdoor installation type device according to the present invention, FIG. 1 is a plan view of an upper cover used in the outdoor installation type device of this example, and FIG. 2 shows this example. 3 is a front view of the upper lid used in this example, FIG. 4 is a side view of the upper lid used in this example, FIG. 5 is an enlarged front view of FIG. 4, and FIG. 6 is an outdoor installation of this example. It is a side view of a type | mold apparatus.

  This example shows an upper lid 2 of an example applied to a square tube type outdoor installation type electric water heater, which is a kind of square tube type outdoor installation type device.

  The upper lid 2 of this example also has a rectangular or quadrangular structure as viewed from above, which is covered with a rectangular tube or rectangular tube 1. Similarly to the above, the rectangular upper lid 2 is also provided with a rectangular upper surface plate 2a that closes the opening of the upper end 1u of the deep rectangular cylindrical container 1, and a container 1 that is integrally provided around the container and protrudes downward. It has the structure provided with the fitting cylinder part 2b of the shallow square cylinder shape fitted to.

In the upper lid 2 of this example, the rectangular upper surface plate 2a is raised above the rear part of the contact part 7a supporting the upper end 1u of the container 1 and the contact part 7a at a position corresponding to the front surface 1a of the container 1. A raised portion 8a is provided. The raised portion 8a has a mountain shape with inclined surfaces on both sides of the top portion. In the rear part of the raised part 8a, an inclined surface 9 in which the raised height gradually decreases toward the rear is provided halfway up to the rear end of the upper surface plate 2a. The length toward the rear end side of the inclined surface 9 is a length that allows a part of rainwater flowing down from the inclined surface 9 to flow down along the side surface 1b of the container 1 viewed from the front surface 1a. In this example, the inclined surface 9 is terminated at a position ahead of the center portion of the upper surface plate 2a. Specifically, the inclined surface 9 is provided in front of the upper surface plate 2a over a portion of about 1/3 in the front-rear direction. Further, the upper surface plate 2a is provided with a pair of side ridge portions 8b that are connected to both lateral ends of the ridge portion 8a and both lateral ends of the inclined surface 9 and extend to the rear end side of the upper surface plate 2a. ing. Inclined surfaces 9 are provided down below the upper end face of the raised portion 8a and a pair of side ridges 8b. Further, a reinforcing rib 10 is projected from the top plate 2a so as to protrude upward at the center in the width direction when viewed from the front surface 1a of the container. The reinforcing rib 10 is provided so as to partially cut the inclined surface 9 between the pair of side raised portions 8b. The reinforcing rib 10 terminates between the center position of the upper surface plate 2a and the rear end.

  Such an upper lid 2 is placed on the container 1 as shown in FIG. At this time, the upper lid 2 is supported by the abutting portion 7a of the upper surface plate 2a being placed on the upper end 1u of the container 1 on the front side, and the abutting portion 7b of the upper surface plate 2a and the upper surface plate 2a on the left and right sides. Both sides on the rear side are supported by being placed on the upper end 1 u of the container 1, and the rear part of the upper surface plate 2 a is supported by being placed on the upper end 1 u of the container 1. For this reason, since each hole provided in the fitting cylinder part 2b of the upper lid 2 matches the corresponding hole in the upper part of the container 1 and is automatically held in that state, another worker supports the upper lid 2. Even without this, one worker can fix the upper lid 2 to the container 1.

  Further, a raised portion 8a raised above the rear end portion of the abutting portion 7a is provided, and an inclined surface 9 in which the raised height gradually decreases rearward from the raised portion 8a from the front surface 1a of the container 1. Since it is provided up to the middle part to the rear end of the seen upper surface plate 2a, the rain water falling on the upper surface plate 2a hardly flows to the front surface 1a side of the container 1, and flows backward along the inclined surface 9. The contamination of the front surface of the container 1 due to rain water can be prevented. Further, since the inclined surface 9 is provided up to the middle of the upper surface plate 2a as viewed from the front surface 1a of the container 1, the rain water falling on the upper surface plate 2a also flows to the rear of the side surface 1b of the container 1. Thus, the corrosion resistance of the rear surface of the container 1 can be improved. In addition, since the upper surface plate 2a of the upper lid 2 is not provided with a groove for drainage, the groove is clogged with dust or the like, so that the drainage cannot be performed and the corrosion of the upper surface plate 2a is promoted. Can be avoided.

  In addition, since a pair of side ridges 8b extending to the rear end side of the upper surface plate 2a are provided so as to be connected to both ends in the horizontal direction of the ridges 8a and both ends in the horizontal direction of the inclined surface 9, the upper lid 2 is provided. It is possible to prevent rainwater from flowing down to the front of the side surface 1b of the container 1. Further, since the inclined surface 9 is lowered below the upper end surfaces of the raised portions 8a and the pair of side raised portions 8b, the top portions of the raised portions 8a and the pair of side raised portions 8b serve as weirs, and rainwater Can be satisfactorily suppressed from flowing to the front part 1a of the container 1 and the front part of the side face 1b.

  Further, the length toward the rear end side of the inclined surface 9 is a length that allows a part of rainwater flowing down from the inclined surface 9 to flow down along the side surface 1b of the container 1 viewed from the front surface 1a. Therefore, rainwater can be allowed to flow from the upper lid 2 along the rear portion of the side surface 1b of the container 1.

  Moreover, since the reinforcing rib 10 which protrudes upwards is provided in the upper surface board 2a, the mechanical strength of the upper cover 2 can be reinforced.

  Note that the side raised portions 8b and the inclined surface 9 can be provided up to just before the rear end of the upper surface plate 2a.

  FIG. 7 is a perspective view of the upper lid showing a second example of the best mode of the outdoor installation type apparatus according to the present invention.

Unlike the first example, the top lid 2 has the tops of the side raised portions 8b and 8b and the inclined surface 9 flush with each other.

Even with such a structure, substantially the same effect as in the first example can be obtained. However, in this case, since there is no portion that becomes a weir at the top of the side raised portions 8b, 8b, the effect of the above-described weir is lost.

  FIG. 8 is a perspective view showing a third example of the best mode of the outdoor installation type apparatus according to the present invention.

  In this example, an example in which the present invention is applied to a case where the container 1 is cylindrical and the shape of the upper lid 2 viewed from above is circular is shown.

  In the upper lid 2 of this example, the upper surface plate 2a includes a contact portion 7 that supports the upper end 1u of the container 1 at a position corresponding to the side portion from the front surface 1a of the container 1, and a circular upper surface plate 2a. An arcuate raised portion 8 raised upward is provided on the inner side toward the center. On the center side of the upper surface plate 2a having a circular shape from the raised portion 8, an inclined surface 9 having a raised height gradually decreasing toward the rear is provided from the rear end to the front portion of the upper surface plate 2a. The inclined surface 9 is provided below the upper end surface of the raised portion 8. In this example, the inclined surface 9 is provided in front of the upper surface plate 2a over about 2/3 of the front-rear direction.

  Even with such a structure, substantially the same effect as in the first example can be obtained. The inclined surface 9 may be flush with the upper end surface of the raised portion 8 on the front surface 1a side of the container 1.

  The raised portions 8, 8 a, 8 b and the inclined surfaces 9 in the above examples are provided by press molding on the upper surface plate 2 a, but can also be provided on the upper surface plate 2 a by welding or bonding.

  Further, the reinforcing rib 10 may be provided as necessary.
