Title: Liquid supplying device
Inventor: KAWASAKI HIROSHI
IPC: F24H1/00
Filed: 1982-12-14
Abstract: PURPOSE:To confirm the time when a liquid supply is required and the time when supply is finished by one lead switch, by constituting a liquid switch by the lead switch, a first float having magnetism, and one more second float. CONSTITUTION:When a liquid is inputted through an injecting port 13, a first float 7 is lifted. The float 7 hits a second float 8 and stops once. A lead switch 1 is operated and a lamp 12 is turned ON. When the liquid is further added, the second float 8 begins the rotation around a shaft 9, and the contact position with the first float 7 is lifted. The distance between the position of a magnet 6 of the first float 7 and the lead switch 6 becomes large, the action of the lead switch 1 is stopped, and the lamp 12 is turned OFF. Thus it is found that the liquid injection should be stopped. When the injection is finished, the liquid flows out of a water discharging port 11. When the liquid level W is lowered below the water discharging port 11, the lead switch 1 is acted again, the lamp is turned ON, thereby indicating the filled up state of the liquid in a container 5.
