JP 2006-64339 A (page 2-3, FIG. 1)

  The hot water storage type water heater of Patent Document 1 is self-supporting with three support legs during transportation, storage, cargo handling, etc., but the water heater is tall and unstable with three support legs on top. Therefore, the water heater, especially its upper part, is likely to roll, and this may damage the equipment provided in the water heater, the wiring and piping connecting them, and in some cases the water heater may fall over. It was.

  The present invention has been made to solve the above-described problems, and provides a hot water storage type water heater that ensures stability in a self-supporting state during transportation, storage, cargo handling, etc., and prevents rolling. It is intended to provide.

The hot water storage type hot water heater according to the present invention has a bottom plate, a covered main body case mounted on the bottom plate, and three installation legs on the lower surface. The installation legs pass through the bottom plate and pass through the bottom case. In the vicinity of the installation leg, and provided with a plurality of roll prevention members whose lower end is located on the same plane as the lower end of the installation leg in the vicinity of the installation leg. is there.

  According to the present invention, it is possible to stably stand by itself during transportation, storage, cargo handling, etc., and the roll can be greatly suppressed, so that built-in equipment, wiring, piping, etc. are not damaged, It is possible to obtain a hot water storage type hot water heater that does not fall over.

[Embodiment 1]
FIG. 1 is a schematic explanatory view of a hot water storage type water heater according to Embodiment 1 of the present invention, and FIG. 2 is a cross-sectional view taken along line AA of FIG.
Installation legs 3a, 3b, 3c are provided at positions corresponding to the apexes of the equilateral triangle at the lower part of the cylindrical hot water storage tank 2 constituting the hot water storage water heater 1, and are provided on the rectangular bottom plate 5. The through holes 7a, 7b, 7c are inserted and fixed, and protrude from the lower surface.

  On the bottom plate 5, a main body case 6 having a square cross section is provided so as to cover the hot water storage tank 2 to form an outer casing, and one installation leg 3 a side or two installation legs are provided. It is installed with either the 3b or 3c side as the front (front). Although not shown, an electric heater, a heat pump heating means, and wiring and piping for connecting them are arranged between the hot water storage tank 2 and the main body case 6.

Reference numerals 20a and 20b denote roll preventing members provided on the lower surface of the bottom plate 5. The lower end portions thereof are located on the same plane as the lower end portions of the installation legs 3a to 3c, and can be accommodated in the main body case 6 as required. It is like that.
These roll prevention members 20a and 20b are orthogonal to both sides of one installation leg 3a located in the vicinity of the center of one side of the bottom plate 5, that is, the side facing the one installation leg 3a. It is installed near the corner where both sides meet.

FIG. 3 shows an example of a structure for mounting the roll preventing members 20a and 20b (may be described as 20 in the following description) to the bottom plate 5. The bottom plate 5 is provided with an insertion hole 8 for a roll preventing member 20, a screw insertion hole 9 is provided on one side of the insertion hole 8, and a screw hole 10 is provided on the other side. .
In addition, fixing pieces 21a and 21b bent in opposite directions are provided at both upper and lower ends of the roll prevention member 20, and screw holes 22 are provided in the upper fixing piece 21a and lower fixing pieces. A screw insertion hole 23 is provided in 21b.

  When the roll preventing member 20 as described above is protruded downward from the bottom plate 5, the roll preventing member 20 is lowered along the insertion hole 8 as shown in FIG. It abuts on the upper surface of the bottom plate 5. At this time, the screw insertion hole 9 of the bottom plate 5 and the screw hole 22 of the fixing piece 21a are aligned. Next, the screw 24 a inserted into the screw insertion hole 9 from the lower surface of the bottom plate 5 is screwed into the screw hole 22 of the fixing piece 21 a to fix the roll prevention member 20 to the bottom plate 5.

  When the roll prevention member 20 is housed in the main body case 6, first, the screw 24a is removed, and the roll prevention member 20 is pushed up along the insertion hole 8 as shown in FIG. The fixing piece 21 b is brought into contact with the lower surface of the bottom plate 5, and the screw insertion hole 23 is aligned with the screw hole 10 of the bottom plate 6. Then, the screw 24b inserted into the screw insertion hole 23 is screwed into the screw hole 10 and fixed. Thereby, the roll prevention member 20 is accommodated in the main body case 6.

  FIG. 4 shows another mounting structure of the roll prevention member 20. In this example, engaging portions 11a and 11b that open toward the insertion hole 8 are provided on the upper surface on one side and the lower surface on the other side of the insertion hole 8 of the bottom plate 5. Further, the roll prevention member 20 is formed in a columnar shape, and locking plates 25a and 25b are provided on the upper and lower sides thereof, and locking pieces 26 that are locked to the engaging portions 11b on the upper surface of the lower locking plate 25b. Is provided.

  In this example, when the roll preventing member 20 is protruded downward from the bottom plate 5, the roll preventing member 20 is lowered and the locking plate 25a is brought into contact with the upper surface of the bottom plate 5, as shown in FIG. The locking plate 25a is locked to the engaging portion 11a by rotating in contact. As a result, the roll prevention member 20 is locked to the bottom plate 5.

When the roll preventing member 20 is accommodated in the main body case 6, first, the roll preventing member 20 is rotated to disengage the locking plate 25a from the engaging portion 11a, thereby releasing the lock. Next, as shown in FIG. 4B, the roll prevention member 20 is raised, and when the lower locking plate 25 b approaches the bottom plate 5, the roll prevention member 20 is rotated to engage the locking piece 26. Lock to the part 11b.
As mentioned above, although the attachment structure to the baseplate 5 of the roll prevention member 20 was demonstrated by FIG. 3, FIG. 4, this is an example and it does not limit to this, Other structures may be implemented suitably. it can.

In the present embodiment configured as described above, when the hot-water storage water heater 1 is transported, stored, or handled, the roll prevention members 20a and 20b are provided as shown in FIGS. Project downward from the bottom plate 5.
Thereby, for example, the hot water storage type water heater 1 that is placed independently on a loading platform or a base includes a substantially tripod-shaped installation leg 3a to 3c provided in the hot water storage tank 2 and the vicinity of both sides of the single installation leg 3a. In this case, since the roll is stably supported by the five legs with the roll prevention members 20a and 20b provided on the bottom plate 5, the roll can be greatly suppressed.

For this reason, equipment, wiring, piping, and the like provided in the outer casing 5 are damaged due to the shaking of the hot water heater 1 itself or the collision of the hot water heater 1 with other members, articles, or transportation facilities. In addition, the hot water storage water heater 1 itself does not fall down.
Furthermore, since the roll prevention member 20 can be accommodated in the main body case 6 as necessary after the hot water storage water heater 1 is installed, the space in this portion can be widened and used effectively.
