摘要:
A hot water dispensing system comprises a one-piece plastic tank having a main heating chamber, an expansion chamber, and an air collection chamber. The air collection chamber is disposed generally below the expansion chamber and alongside the main heating chamber. The main heating chamber is in fluid communication with the expansion chamber and the air collection chamber. The hot water dispensing system also includes a temperature control system having a heating element, a metal temperature sensing bracket, and a thermostat. The heating element is disposed within the plastic tank and connected to a metal temperature sensing bracket disposed outside the tank. The excellent conductive properties of a metal sheath that connects the metal temperature sensing bracket to the heating element allow the metal temperature sensing bracket to simulate changes in the temperature of water in the tank. The thermostat is mounted to the metal temperature sensing bracket and measures a temperature of the metal temperature sensing bracket and activates or deactivates a heating element in response to the measured temperature of the metal temperature sensing bracket.

A self-latching handle for storage batteries includes a cam mechanism formed integrally with the ends of the battery handle, the cam mechanism cooperating with the battery housing as the battery handle is rotated downwardly from a vertical attachment position to a horizontal storage position to lift the ends of the battery handle to move pivot post portions of the battery handle into pivot apertures formed in the cover of the battery housing and to lock the battery handle to the battery housing while permitting the battery handle to be pivoted between the horizontal storage position and a vertical use position without becoming detached from the battery housing.
