Abstract

PURPOSE:To prevent an abnormal noise in a water controlling device, by providing a spring to the inside wall of a bypass passage which is contacted by a ball, on the surface of which a buffering material is coated. CONSTITUTION:A spring 9 is provided to the inside wall of a bypass passage 4 which is contacted by a ball 6 coated with a buffering material 8, while the tip of a spring 10 is bent as shown in the drawing. Leaving the hot-water temperature controlling knob 3 in a water body 1 open and when the outdoor temperature goes down below the freezing point, a low temperature actuated draining device 2 functions to drain water. But the ball 6 remains seated on a ball seat 7 because the drained water is only a small quantity and the specific gravity of a ball is large as it is made of metal. Usually, when a water heater is used, the ball 6 is floated up separating from the ball seat 7 and is stopped by the tip of a spring 10. At that time the ball 6 hits the wall surface of a bypass passage 4. But in this case abnormal noises caused by the ball 6 contacting with a metal can be prevented, because the ball 6 is coated with the buffering material 8, and the spring 9 is provided to the inside wall of a bypass passage 4 being in contact with the ball 6.

This relates to the structure of the water body that prevents abnormal sounds from being generated when it hits the water.

を防いでいる。Recently, there has been an increase in the number of water heaters that are installed outdoors due to concerns about safety and installation space. The low-temperature water drain actuator 2 shown in the figure is attached to the hot water outlet side of the water heater to prevent water from draining from the low-temperature water drain actuator 2 and the equipment from freezing and breaking when the outside air drops below freezing.

ないようにしていた。Furthermore, if the outside temperature is below freezing and the low temperature water drain actuator 2 is activated with the hot water temperature control knob 3 of the water body 1 open to open the bypass passage 4, water will flow to the bypass passage 4 side. , does not flow to the heat exchanger 5 side, and therefore the heat exchanger 6
In order to prevent water from freezing and breaking, a ball 6 is provided at the bottom of the hot water temperature control knob 3 of the water body 1 to prevent water from flowing to the bypass passage 4 side when the low temperature water drain operation device 2 is operating. I tried not to.

う欠点があった。However, in the above structure, when the hot water temperature control knob 3 of the water body 1 is opened and a normal water heater is used, the ball 6 rises due to the differential pressure when the water volume is within the operating range of the water body 1.
Since the water flows through the bypass passage 4, the ball 6 hits the wall surface of the bypass passage 4 at that time, causing abnormal noise.

本発明は上記従来の欠点を解消したもので、以下その実
施例を添附図面とともに説明する。The present invention eliminates the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to the accompanying drawings.

うな構成になっている。In FIG. 4, a rubber or resin cushioning material 8 is coated around a metal ball 6, and a spring 9 is provided inside the wall surface of the bypass passage 4 that comes into contact with the ball 6. In order to prevent the
The tip of the ball 6 is bent and the ball 6 stops at the bent point.

におさ捷っている。In the above structure, when the outside temperature drops below freezing with the hot water temperature control knob 3 of the water body 1 open, the low temperature water drain operation device 2 operates to drain water, but the amount of water is small and the ball 6 is Since it is metal and has a high specific gravity, the ball 6 is attached to the valve seat part 7.
I'm in a hurry.

それで水ボデー１を通った水はすべて熱交換器５を流れ
るようになるので、氷点下を切っても熱交換器６が凍結
して破壊することはなくなる。Therefore, all the water that has passed through the water body 1 flows through the heat exchanger 5, so that the heat exchanger 6 will not freeze and be destroyed even if the temperature drops below freezing.

端部で止壕る。Next, when using a normal water heater, the amount of water flowing through the water body 1 increases, so a pressure difference is generated between the part where the water enters the water body 1 from the heat exchanger 5 and the bypass passage part 4, and the ball 6 is separated from the valve seat portion 7 and floats up, and is stopped at the tip of the spring 1o.

Since the ball 6 is coated with a cushioning material 8 and the spring 9 is provided inside the wall surface of the bypass passage 4 that comes into contact with the ball 6, abnormal noise due to contact between the ball 6 and metal is eliminated. .

以上のように本発明によれば以下の効果が得られる。As described above, according to the present invention, the following effects can be obtained.

It will not be destroyed.
