Abstract

PURPOSE:To improve the stability of effluent hot-water by constructing a title hot-water boiler including an air exhaust mechanism at the top of a closed hot-water storage tank. CONSTITUTION:Bubbles produced during heating by a hot-water heater 7 are stored at the top 3 in a hot-water storage tank 2. There is provided an air exhaust mechanism 4, so that the mechanism 4 can exhaust the bubbles stored at the top 3 to the outside of the hot-water storage tank 2 without causing those bubbles to flow out from a hot-water outlet 8 to a downstream side. Accordingly, the bubbles can be prevented from interrupting the operation of a pump 9 and hence effluent hot-water from a faucet 10 and the like can further be stabilized. The air exhaust mechanism 4 may be constructed by directly mounting a relief valve 5 on the top 3 of the hot-water storage tank 2, or in case where exhausted bubbles are desired to be guided to another place, one end of a pipe 6 may be connected with the top 3 of the hot-water storage tank 2 to communicate with each other, and the relief valve 5 may be mounted on the other end of the pipe 6.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a hot water boiler.

(Prior Art) In a conventional boiler having a closed hot water storage tank, for example, as shown in FIG. 2, only a hot water inlet d and a hot water outlet e are provided at the top C of the hot water storage tank b of the boiler a.

(Problem to be solved by the invention) As mentioned above, a conventional boiler a having a closed hot water storage tank b
In , when the hot water is heated by the water heater r, bubbles generated in the hot water accumulate in the top C of the hot water storage tank b, and when these bubbles flow out downstream from the outlet e along with the hot water, the operation of the pump g is interrupted. As a result, a problem arises in that hot water from the faucet h etc. becomes unstable. For this reason, conventionally,
An air separator i is provided on the downstream side of the hot water storage tank b to remove air bubbles from the hot water, but air bubbles are often discharged from the faucet h, making it impossible to obtain a satisfactory effect. Achieving stable hot water supply has become a challenge.

The present invention aims to solve such problems.

In addition, in FIG. 2, the symbol j is a pump.

(Means for Solving the Problems) The configuration of the present invention will be explained based on FIG. 1 corresponding to an embodiment. First, the hot water boiler 1 according to claim 1
In this example, an air exhaust mechanism 4 inside the hot water tank 2 is provided on the top 3 of the closed hot water tank 2. Next, in the hot water boiler 1 described in item 2, the air exhaust mechanism 4 described in item 1 above is configured with a relief valve 5.

The hot water boiler 1 described in item 3 connects the air exhaust mechanism 4 described in item 1 to a pipe 6 communicating with the inside of the hot water tank 2, and a pipe 6.
A relief valve 5 is provided at the tip of the valve.

(Operations and Examples) Air bubbles generated during heating by the water heater 7 accumulate in the top 3 of the hot water storage tank 2, but since an air exhaust mechanism 4 is provided here, the air bubbles are removed from the top by this mechanism 4. Since the air bubbles accumulated in the hot water tank 3 can be discharged to the outside of the hot water storage tank 2, and therefore the air bubbles will not flow out downstream from the hot water outlet 8, it is possible to prevent the air bubbles from interfering with the operation of the pump 9. The hot water flowing from the faucet 10 or the like can be further stabilized.

The air discharge mechanism 4 may be configured by attaching the relief valve 5 directly to the top 3 of the hot water storage tank 2, or if it is desired to guide the discharged air bubbles elsewhere, one end of the pipe 6 may be connected to the top 3 of the hot water storage tank 2.
The relief valve 5 may be attached to the other end of the pipe 6 by connecting it to the top 3 of the pipe 6 to communicate with each other. At this time, if the pipe 6 is tilted and the relief valve 5 is positioned higher than the top 3 of the hot water tank 2, air bubbles can be discharged more effectively.

(Effects of the Invention) As described above, the hot water boiler of the present invention has an extremely simple configuration that only includes an air exhaust mechanism at the top of the closed hot water storage tank.
This has the effect of improving the stability of hot water.
