Description

  The present invention relates to a hot water storage tank unit including a hot water storage tank surrounded by a casing.

  In general, this type of hot water storage tank unit 100 includes a hot water storage tank 101, a substantially rectangular parallelepiped casing 102 that surrounds and fixes the hot water storage tank 101, and legs 103 that support the casing 102. . The housing 102 is formed by a front plate 104 that can be opened for maintenance, a back plate 105 that is fixed to each other with screws, two side plates, a top plate 106, and a bottom plate (not shown). Near the back plate 105 side of the top plate 106, a carrying handle 107 is attached by screws with screws 108.

  The hot water storage tank unit 100 is often transported by a plurality of human powers by laying down the casing 102 when transported, installed and constructed, or carried during removal, etc. due to disposal. The work is facilitated by having the leg 103 connected to the bottom plate and the handle 107 provided on the top plate 106 on the other hand. In addition, the handle 107 is generally a system in which two resin-made hats are attached to the top plate 106 mainly from the viewpoint of cost.

  However, in the hot water storage tank unit 100 that is often installed outdoors, when the time interval from installation to removal is long, the resin handle 107 is greatly affected by ultraviolet rays or the like, and deteriorates. However, it was difficult to fully exhibit its strength. On the other hand, considering the strength of the handle 107 at the time of removal, the handle 107 may be made of metal, but in this case, cost reduction is difficult. In addition, as a means for fixing these handles 107 to the casing 102 such as the top plate 106, it is often the case that the handle 107 is fixed with about two thin dedicated screws per handle 107. Corrosion and damage may occur, and reliability was low.

By the way, as shown in Patent Document 1, in a hot water tank unit in which a hot water supply tank is installed on a base plate and a heat exchanger is attached to a heat exchanger mounting frame provided at the upper part of the hot water tank, the top surface of the hot water tank unit There is known a hot water tank unit in which a handle for transporting a hot water tank unit is attached to a heat exchanger mounting frame in a state where a top plate covering the base plate is sandwiched. However, since this hot water tank unit uses a carrying handle for the top plate, if the carrying handle is made of resin as described above, it will depend on the strength of the carrying handle when it is installed outside for a long time. However, there is a problem that the cost is lowered when the metal is used.

Moreover, since the top plate 6 can be fixed at a large number of locations with the peripheral wall plate 5 and a plurality of screws, the support strength can be increased and safety during transportation compared to the conventional handles attached with a small number of thin dedicated screws. Increased reliability and reliability.

  Moreover, the overhang | projection part 6a is easily formed only by bending the top plate 6 in multiple times. Accordingly, the processing of the overhanging portion 6a can be easily performed mainly by processing only the top plate 6 without specially crafting the shape of the peripheral wall plate 5 or the like, so that the cost can be reduced.

  A hot water storage tank unit according to a second embodiment of the present invention will be described with reference to FIG. This embodiment has basically the same configuration as that of the above embodiment, but the peripheral wall plate has a vertical projection shape at the upper end of at least one side viewed from the vertical direction larger than that of the peripheral wall plate. The top plate is formed to be equal to the vertical projection shape of the peripheral wall plate and is joined to the bent portion of the peripheral wall plate.

  As shown in FIG. 4, the housing 3 of the present embodiment includes a bent portion 52 a formed in an L shape at the upper end portion of the back plate 52 that is one side of the peripheral wall plate 5, an extension plate 61 on the top plate 6, and The extending plate 61 is provided with an extending portion 6a formed in an L shape by the extending plate 62 having a right angle. The bent portion 52a is formed by a bent plate 52b obtained by bending the upper end portion of the back plate 52 at a right angle to the back plate 52 and a bent plate 52c bent at a right angle upward from the end of the bent plate 52b. Here, the bent portion 52a is formed by being bent so that the vertical projection shape seen from the vertical direction is larger than the vertical projection shape A of the peripheral wall plate 5 described above.

  In the above configuration, the protruding portion 6a of the top plate 6 covers the peripheral wall plate 5 including the bent portion 52a so as to cover from above, and the extending plate 62 of the protruding portion 6a and the bent plate 52c of the bent portion 52a are Further, the extension plate 62 and the bending plate 52c are fixed by being screwed by the screw 15. Thereby, the overhang | projection part 6a and the bending part 52a can form the crank-shaped block 16 (height h, protrusion length V) with a mutual L-shaped board piece. Here, the protrusion length V is the length of the bent plate 52b. Therefore, when the hot water storage tank unit 1 is transported, the housing 3 can be supported by hand using the block 16 as a handle. Further, the side wall of the crank-shaped block 16 is formed substantially uniformly by the overhanging portion 6a and the bent portion 52a. Therefore, when the housing 3 is held, the load of the housing 3 is on the top plate 6 side and the back plate 52. Since the load is applied substantially evenly to the side, the load is less biased, the distortion of the shape of the housing 3 is reduced, and the safety when the housing 3 is carried increases.

  Thus, according to the hot water storage tank unit of the second embodiment, the overhanging portion 6a of the top plate 6 and the bent portion 52 of the back plate 52 in the peripheral wall plate 5 perform a handle action integrally. Therefore, it is possible to prevent the load from being biased to one of the top plate 6 and the peripheral wall plate 5 during transportation, the load is dispersed, and the safety of the casing strength during transportation is increased.

  In addition, this invention is not restricted to the said embodiment etc., Furthermore, it can change suitably. For example, in the present embodiment, the overhang portion is formed on the back plate side, but it may be a peripheral wall plate such as a side plate other than the back plate, and may also be provided on a plurality of wall plates such as the back plate and two side plates. You may form simultaneously. Further, when it is not necessary to remove the front plate, safety and reliability are further improved by fixing the front plate portion to the top plate. Further, the fixing between the top plate and each peripheral wall plate is not limited to screws, and other means such as welding may be used.
