Water level sensor and heat exchanger sterilizing and humidifying apparatus having the same

摘要

A water level sensor is closely adhered to a storage tank, and a heat exchanger sterilizing and humidifying apparatus allows the water level sensor to be mounted at the outside of the storage tank, thus having a simple configuration. The water level sensor may include a holder, a cap connected to the holder so as to reciprocate within the holder, a case connected to the cap so as to reciprocate within the holder, a sensor part attached to the case to sense the water level in the storage tank, and a spring located between the holder and the cap, wherein the sensor part mounted at the outside of the storage tank and attached to the case by restoring force of the spring when the storage tank contacts the case may be closely adhered to the storage tank and thus may sense a level of water stored in the storage tank.

主权项

1. A heat exchanger sterilizing and humidifying apparatus comprising:
a kit on which parts to sterilize a heat exchanger are mounted; a storage tank detachably mounted on the kit to receive and store water and to convert the stored water into sterilizing water; a spraying device to receive the sterilizing water generated by the storage tank and to spray the sterilizing water to the heat exchanger to sterilize the heat exchanger; and a water level sensor detachably mounted on the kit and closely adhered to the outer surface of the storage tank without direct contact with water or sterilizing water in the storage tank when the storage tank is mounted on the kit, to sense a water level in the storage tank.
