Abstract
A range hood with features for monitoring the temperature of a cook top located below it is provided. In one example, the range hood includes one or more temperature sensors positioned over the cook top for measuring temperature of the heating elements below. If the measured temperatures(s) exceeds one or more predetermined temperature levels, either with or without a time delay, a notification and/or other remedial response is provided to a user of the appliance. The notification can be, for example, a visual warning projected onto the cook top and/or an audible alarm. Different warnings can be provided based on different temperature levels as measured by the temperature sensors.
Claims17
A range hood with a temperature monitoring system for a cook top, the cook top having at least one heat source positioned about a cook top surface, the range hood comprising:
- a temperature sensor positioned above the cook top and configured for detecting the temperature of the heat source of the cook top, a cooking utensil on the heat source, a food in the utensil, or a combination thereof;
- a warning device comprising:
- an illumination warning device configured to provide a first notification comprising a visual warning to a user of the appliance if said temperature sensor detects a temperature over a first predetermined temperature level, TL1, for a first predetermined time interval, Δt1, that is dependent upon the temperature detected by the temperature sensor, wherein said visual warning is projected onto the cook top at a rate of pulsation that is indicative of a relative temperature increase of the temperature detected by said temperature sensor over the predetermined temperature level, TL1.
A method of monitoring the temperature of a cook top, the cook top having at least one heat source, the method comprising the steps of:
- sensing the temperature of the heat source, a cooking utensil on the heat source, a food in the utensil, or a combination thereof;
- determining whether the temperature measured in said step of sensing exceeds a predetermined level for a predetermined time interval that is dependent upon the temperature measured in said step of sensing, and, if so, then
- providing a warning to a user of the cook top, wherein the warning is a visual notification that is projected onto the surface of the cook top at a rate of pulsation that is indicative of a relative temperature increase of the temperature measured in said step of sensing over the predetermined level.
A method of monitoring the temperature of a cook top, the cook top having at least one heat source, the method comprising the steps of:
- using a temperature sensor positioned above the cook top to determine the temperature of the heat source, a cooking utensil on the heat source, a food in the utensil, or a combination thereof;
- determining whether the temperature measured in said step of sensing exceeds a predetermined level for a predetermined time interval that is dependent upon the temperature measured in said step of sensing, and, if so, then
- providing a warning to a user of the cook top, wherein the warning is a visual notification that is projected onto the surface of the cook top at a rate of pulsation that is indicative of a relative temperature increase of the temperature measured in said step of sensing over the predetermined level.
