Description

[Detailed Description of the Invention] This invention relates to a discharge water evaporation device for a drain safety valve of an instantaneous gas water heater or the like.

The water drain safety valve in instantaneous gas water heaters, etc. is used to release the rise in water pressure that occurs when the water in the water heater becomes abnormally heated, and is generally installed at the bottom of the gas flasher. The water drain safety valve also serves as a drain valve to release residual water inside the appliance, as it is necessary to prevent damage to the appliance that occurs when water freezes in the winter.

Therefore, conventional systems have the disadvantage that when water is discharged due to an increase in water pressure, or when water is drained to prevent freezing, the running water pollutes the interior of the room.

This idea uses an evaporating dish to catch the water discharged from the water drain safety valve and quickly evaporates it, while at the same time moving the evaporating dish when draining water, another large container is placed below the drain valve to receive a large amount of residual water. In this way, the above-mentioned drawbacks of the conventional method are corrected.

That is, the gist of the invention is that in an instantaneous gas water heater or the like, the evaporating dish 1, which receives water discharged from the drainage safety valve A, can be freely swung by a pair of support rods 3, 3', and the water can be drained. A moisture absorbing container 2 made of a porous material was suspended directly below the safety valve A, and a moisture absorbing container 2 made of a porous material was installed in the evaporating dish at a distance from the water draining safety valve A to receive dripping discharge water and absorb and evaporate the water. This relates to a discharge water evaporation device for a water heater safety valve.

Next, an embodiment of the present invention will be explained based on the drawings. The figure shows an evaporating dish 1 provided directly below the drainage safety valve A, in which a moisture absorbing container 2 made of unglazed ceramics or other porous material is housed. In this embodiment, the water discharged from the water drain safety valve A is received, and the evaporating dish 1 is supported by a support ring 4 fixed to the lower ends of a pair of swingable support rods 3゜3'. This is suspended from the gas flasher B side directly below the water drain safety valve A, and is separated from the moisture absorption container 2 by an appropriate distance so that the safety valve can be easily removed. It's convenient.

Therefore, according to this embodiment, the water discharged from the drainage safety valve A enters the moisture absorption container 2 in the evaporating dish 1 directly below, absorbs moisture over a wide area, and has the effect of efficiently evaporating from a wide area.

The water drain safety valve A is a normally closed valve in which a valve 8 is pressed and held by a spring 9.

Since this device has the above-mentioned configuration, when the water in the water heater becomes abnormally heated due to the residual heat immediately after hot water has stopped dispensing, the water in the appliance expands, but the valve 8 is pressed against the spring 9 of the drain safety valve. Open,
The water is discharged into the evaporation dish 1 located directly below, and connected to the moisture absorption container 2 made of porous material on the evaporation dish, which quickly absorbs the discharged water. Can be evaporated well.

In addition, since the moisture absorption container is provided in a larger evaporation tray, even if the discharged water overflows from the moisture absorption container, it can be caught by the evaporation tray, so that unlike conventional methods, the discharged water does not flow into the room and stain the floor etc. It has the effect of preventing this.

Note that when the water drain safety valve A performs the above-mentioned function as a pressure safety valve, the amount of water discharged is usually a small amount of several CC, so the moisture absorption container itself may be small, so it is normally hung directly below the water drain safety valve A as shown in the figure. However, when draining water from the equipment to prevent freezing in the winter, a container with a fairly large capacity is required, so an evaporating dish or moisture absorption container is too small, so a separate large container is required. It shall be located below the drainage safety valve.

In this case, of course, all you have to do is move the hanging evaporation plate and moisture absorption container to the side.

As explained above, in this invention, the evaporating dish and the moisture absorption container are swingably held directly below the drainage safety valve, so that the water discharged from the drainage safety valve during normal use can be received by the evaporation dish and the moisture absorption container. It is extremely convenient in practical use, as it does not cause any problems when draining water during the winter.
