Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a solar water heater, and more particularly to a solar water heater equipped with a circulation pump for forcibly circulating a heat medium.

[Conventional technology]

Conventionally, the hot water tank of a solar water heater, in which the heat collector and the hot water storage tank are installed separately on both sides of the roof ridge, has a heat insulating material inside the case 1 made of resin or metal, as shown in Figure 3. It is stored through 2. The hot water storage tank 3 includes an outgoing pipe 8 for sending the heat medium in the hot water storage tank 3 to a heat collector (not shown) and a return pipe 9 for returning the heat medium from the heat collector to the hot water tank 3.
is provided. A water supply pipe 7 equipped with a hot water separator 5 and a ball tap 6 installed in the hot water storage tank 3
After supplying the heat medium into the hot water storage tank 3, the heat medium is sent to the heat collector side by the circulation pump 4 provided in the outgoing pipe 8, and is heated by the heat collector and returned from the return pipe 9 to the hot water storage tank. Hot water is stored in the tank 3, and the stored hot water is taken out from the hot water tank 3 through a hot water sampling pipe 10.

[Problem that the invention attempts to solve]

However, with this conventional solar water heater,
As shown enlarged in FIG.
Since the circulation pump 4 is directly fixed in place, the screw part for fixing the circulation pump 4 is located at the bottom of the circulation pump 4, making it extremely difficult to attach or remove the circulation pump 4. There was a problem in that maintenance and inspection of the pump 4 could not be easily performed. In particular, when the pump inspection port 12 is provided above the case 1 or is narrow, it is extremely difficult to install or remove the circulation pump 4.

The present invention was devised in view of the above-mentioned problems, and its purpose is to simplify the installation and removal work of the circulation pump, and to make maintenance and inspection of the circulation pump part extremely easy. The purpose of this project is to provide a water heater that utilizes solar heat.

[Means for solving problems]

According to the present invention, the heat collector and the hot water storage tank housed in the case are connected by an outgoing pipe and a return pipe,
In a solar water heater equipped with a circulation pump that forcibly circulates a heat medium in the outgoing piping, a pedestal and a support member each having a bottom piece, a side piece, and a top piece are provided, and the bottom piece of the pedestal is connected to the inner bottom of the case of the hot water storage tank. At the same time, place the top piece of the support member on the top piece of the pedestal, and screw the top piece of the support member to the top piece of the pedestal with the tip of the bottom piece of the support member colliding with the side piece of the pedestal. There is provided a solar water heater characterized in that the circulation pump is fixed to a side piece of the support member, thereby achieving the above object.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to the accompanying FIGS. 1 and 2.

Note that the same parts as in the conventional example are given the same reference numerals.

FIG. 1 is a cross-sectional view of a part of a hot water storage tank in which a circulation pump is housed, showing an embodiment of the solar water heater of the present invention, where 1 is a case, 2 is a heat insulating material, 3 is a hot water storage tank, and 4 is a circulation pump. It's a pump.

The case 1 is made of polyethylene resin or the like, and a hot water storage tank 3 is housed therein via a heat insulating material 2 made of styrene foam or the like. A pump inspection port 12 is provided at the top of the case 1 for inspecting the circulation pump 4 portion.

The hot water storage tank 3 is made of polyethylene resin or the like, and a pump connection port 3a for connecting a circulation pump 4 is provided at the lower rear thereof, as shown in FIG.

A protrusion 1a is formed at the attachment part of the circulation pump 4 on the bottom of the case 1.
A pedestal 13 is fixed on top of a.

The pedestal 13 is composed of a top piece 13a, a side piece 13b, and a bottom piece 13c, and has a generally L-shape as a whole. A bottom piece 13c of this pedestal 13 is fixed to the bottom inside the case 3 by screws 11a and 11b.

A support member 14 is fixed to the pedestal 13. This support member 14, almost like the pedestal 13, includes a top piece 14a, a side piece 14b, and a bottom piece 14c.
It is generally U-shaped as a whole. This support member 14 has an upper piece 1 of the support member 14.
4a on the upper piece 13a of the pedestal 13, and the tip of the bottom piece 14c of the support member 14 is placed on the side piece 13b of the pedestal 13.
The upper piece 14a of the support member 14 is screwed and fixed to the upper piece 13a of the base 13 with a screw 15a in a state where the support member 14 collides with the upper piece 13a of the base 13.

The circulation pump 4 is fixed to the side piece 14b of the support member 14 so as to face sideways.

In this way, the circulation pump 4 is temporarily fixed to the substantially U-shaped support member 14, and the upper piece 14a of this support member 14 is attached to the upper piece 13a of the pedestal 13 fixed to the inner bottom surface of the case 1 of the hot water storage tank 3. When placed on top and screwed, the circulation pump 4 can be attached or removed using this screwed portion.

[Effect of idea]

As described above, according to the solar water heater according to the present invention, a pedestal and a support member each having a bottom piece, a side piece, and a top piece are provided, and the bottom piece of the pedestal is fixed to the inner bottom of the case of the hot water tank. Place the top piece of the support member on the top piece of the pedestal, and with the tip of the bottom piece of the support member colliding with the side piece of the pedestal, fix the top piece of the support member to the top piece of the pedestal with screws. Since the circulation pump is fixed to the side piece of the support member, the circulation pump can be attached or removed using the screws between the pedestal and the support member, and the screwing part between the pedestal and the support member is higher than the circulation pump. Because of its location, even in solar water heaters where the inspection port for the pump is located at the top of the hot water storage tank case, installation and removal of the circulation pump is simplified, making maintenance and inspection of the circulation pump extremely easy. be able to.
