Description

  The present invention relates to a hot water storage type hot water heater in which a front panel of an outer case containing a hot water storage tank can be easily assembled and rainwater that has entered a gap can be easily drained.

  Conventionally, in this kind of outdoor installation, in order to prevent dirt due to rainwater, a concave passage was formed on the top plate, and rainwater was collected and finally formed on the front panel. It was designed to drain from the ditch to the ground below. (For example, Patent Document 1)

JP 2011-214726 A

  By the way, in this conventional product, before rainwater converges on the concave passage on the top plate, rainwater enters the gap between the side plate and the front panel. It has a problem of causing early deterioration as a cause.

  This invention pays attention to this point, and in order to solve the above-mentioned problems, in particular, the configuration thereof is a hot water storage type hot water heater provided with a pipe connection part protruding slightly forward at the front lower side of the outer case containing the hot water storage tank. In this case, the front panel covering the pipe connection portion of the outer case is attached and attached to an inwardly folded portion formed on the front end portion of both side plates covering the hot water storage tank. The left and right end portions are provided with a placement portion for placing the lower end of the folded portion and the lower end of the left and right end portions of the front panel. The placement portion is provided with a drain outlet for draining rainwater.

  As described above, according to the present invention, since the mounting portion for mounting the lower end of the folded portion and the left and right lower ends of the front panel is formed at the left and right ends of the pipe connection portion, the front panel is temporarily mounted at the time of assembly. It can be placed on the mounting part and it is very easy to assemble, and the mounting part has a rainwater drainage port so that rainwater concentrated on the mounting part can be smoothly routed through the folded part. It can be drained from the drain outlet, and there is no worry of entering the inside and causing rusting and premature deterioration, and can always be used with confidence.

BRIEF DESCRIPTION OF THE DRAWINGS The front view of the hot water storage type water heater which shows one Embodiment of this invention. The right side view. FIG. 2 is a cross-sectional view taken along line A-A ′ of FIG. 1. FIG. 2 is a sectional view taken along line B-B ′ of FIG. 1. The principal part enlarged plan view. FIG.

Next, one embodiment of a hot water storage type hot water heater according to the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a rectangular outer case containing a cylindrical hot water storage tank 2 which is attached to and detached from the back plate 3, the left and right side plates 4, 5, the top plate 6 and the bottom plate 7 for inspection, repair, and installation piping. And a front panel 8.
Reference numeral 9 denotes a pipe connection portion formed of a stepped portion protruding forward so as to form a pipe storage portion 10 for storing each pipe on the front side of the outer case 1, and a connection portion 11 of each pipe is provided on the upper surface. The pipe connection part 9 is fixed through.

  Reference numeral 12 denotes an inwardly folded portion formed at the front side end of the left and right side plates 4 and 5, which is in the abutting state when assembled with the left and right end portions 13 of the front panel 8. Intrusion of rainwater flowing in from the gap into the outer case 1 is prevented in the vertical direction.

  Reference numeral 14 denotes a small semicircular mounting portion that protrudes from the left and right end portions of the pipe connection portion 9. The lower end of the folded portion 12 is mounted and the lower ends of the left and right end portions 13 of the front panel 8 are mounted. The front panel 8 is temporarily placed at the time of assembling so that the assembling can be easily performed.

  15 is a drain outlet formed on the outside of the placing portion 14 directly below the folded portion 12. As described above, rainwater flowing from the gap between the front panel 8 and the folded portion 12 is allowed to flow into the folded portion 12. Rainwater that has flowed down along the wall surface, collected on the mounting portion 14 and drained, and has entered the inside of the folded portion 12 at a front position away from the drain port 15 and has entered the inside from the lower end of the folded portion 12. An auxiliary drain 16 is provided for draining water.

Reference numeral 17 denotes three support legs fixed to the bottom of the hot water storage tank 2 and provided through the bottom plate 7.
18 is a window cover that covers the operation window 20 of the drain plug 19, 21 is a water supply pipe, 22 is a hot water discharge pipe, and 23 is a return pipe.

  Next, the operation of this embodiment will be described. When the front panel 8 is assembled to the exterior case 1, the folded portions 12 of the left and right side plates 4, 5 are bent to the inside of the left and right end portions 13 of the front panel 8. By placing the lower end of the end portion 13 of the front panel 8 on the mounting portion 14 in a state where the front panel 8 is in contact, the front panel 8 is temporarily placed, and the front panel 8 is supported with one hand. Where appropriate, not shown here, but screwed in several places on the front, the assembly of the front panel 8 is completed, by forming the mounting portion 14 on the left and right ends of the pipe connection portion 9, The front panel 8 can be placed once with the left and right end portions 13 in contact with the folded-back portion 12, and can be easily screwed by one person and can be assembled very easily.

  Further, when rainwater enters from the contact portion between the end portion 13 of the front panel 8 and the folded portion 12 due to outdoor installation of the instrument, the folded portion 12 serves as a wall to prevent inflow into the exterior case 1. Since the rainwater which has entered flows down through the turn-back portion 12 and converges on the placement portion 14, the pipe storage portion 10 in which the pipe is accommodated from the drain port 15 provided in the placement portion 14 is used. In addition, a part of the rainwater on the mounting portion 14 flows into the inside of the folded portion 12 through a slight gap between the lower end of the folded portion 12 and the placing portion 14. The rainwater that has flowed into the inside is drained from the auxiliary drainage port 16 to the ground, and the rainwater that has entered from the mounting gap of the front panel 8 is surely drained through the drainage port 15, Will not cause rust by intruding Worry of the period of deterioration is also that with peace of mind can be used over a long period of time without.
