Patent ID: 7172134

Claim:
A freezer alarm apparatus for monitoring the temperature conditions within a freezer compartment of a refrigeration unit that includes a lid and a plurality of adjoined sidewalls, comprising: a housing mountable adjacent to the refrigeration unit; a temperature-sensing bulb for placement within the freezer compartment of the refrigeration unit for monitoring and registering the temperature conditions occurring within the freezer compartment; a selectively adjustable thermostat mounted to the housing and capable of being manually present to one of a plurality of temperature set points; a protective sleeve interposed between the lid and one of the plurality of sidewalls of the refrigeration unit; an elongated, flexible capillary rube extending from the housing and through the protective sleeve to the temperature-sensing bulb for interconnecting the temperature-sensing bulb to the thermostat with the protective sleeve preventing the capillary tube from being damaged when the lid is closed; a buzzer alarm mounted to the housing and in electrical interconnection with the thermostat; an alert light mounted on the housing and in electrical interconnection with the thermostat; and electrical circuitry enclosed within the housing and electrically interconnecting the thermostat to the buzzer alarm and the alert light for allowing the simultaneous activation of the buzzer alarm and the alert light upon determination by the thermostat that the temperature conditions occurring within the freezer compartment have exceeded the temperature set point.
