Abstract

Abstract A domestic cooking or defrosting appliance including a heating region and a camera for obtaining images of food cooking or defrosting within the heating region, wherein the camera outputs video signals to a processor that drives a display means associated with the appliance and/or controls the cooking or defrosting operation of the appliance. The display means is conveniently situated on the appliance to show an easily-viewable image of the food obtained by the camera. The camera is sensitive to infra-red radiation and outputs video signals representative of the heat of the food. The processor can therefore convert infra-red information received from the camera into visible information to create a display on the display means representative of the infra-red information. Such a display is preferably colour-coded in accordance with the local temperature of the food. The appliance (1) is adapted for interaction with a communications network (75) such as the Internet by the addition of a substantially self-contained discrete communications module (12) connectable to the communications network (75), the communications module (12) including display means (20) and command entry means that optionally interact with the appliance (1).

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 62 words
A cooking or defrosting appliance (1) including a heating region (69) and a camera (68) for obtaining images of food (70) cooking or defrosting within the heating region (69), wherein the camera (68) outputs video signals to a processor (24) that drives a display means (20) associated with the appliance (1) and/or controls the cooking or defrosting operation of the appliance (1).
Claim 2
Dependent Claim 30 words
The appliance (1) of Claim 1, wherein the display means (20) is situated on the appliance (1) to show an image of the food (70) obtained by the camera (68).
Claim 3
Dependent Claim 30 words
The appliance (1) of Claim 1 or Claim 2, wherein the camera (68) is sensitive to infra-red radiation and outputs video signals representative of the heat of the food (70).
Claim 4
Dependent Claim 35 words
The appliance (1) of Claim 3, wherein the processor (24) converts infra-red information received from the camera (68) into visible information to create a display on the display means (20) representative of the infra-red information.
Claim 5
Dependent Claim 21 words
The appliance (1) of Claim 4, wherein the display is colour-coded in accordance with the local temperature of the food (70).
Claim 6
Dependent Claim 51 words
The appliance (1) of any of Claims 3 to 5, wherein the processor (24) compares food (70) temperature represented by the infra red image with a stored model and, depending upon variance with the model, sends control outputs to the appliance (1) to vary heating power and/or exposure time to heat.
Claim 7
Dependent Claim 41 words
The appliance (1) of any preceding Claim, wherein the display (20) also performs Internet, e-commerce, or home networking functions and is switchable to display the food (70) in the heating region when the appliance (1) is in use cooking or defrosting.
Claim 8
Dependent Claim 23 words
The appliance (1) of Claim 7, wherein the display (20) switches automatically at the start and end of a cooking or defrosting operation.
Claim 9
Dependent Claim 29 words
The appliance (1) of Claim 8, wherein the camera (68) is fixed and food (70) is moved in relation to the camera (68) during a cooking or defrosting operation.
Claim 10
Dependent Claim 15 words
The appliance (1) of Claim 9, wherein the food (70) is on a turntable (71).
Claim 11
Independent Claim 45 words
A method of cooking or defrosting, comprising obtaining infra-red images of cooking or defrosting food (70) from a camera (68) that outputs video signals to a processor (24), and processing or displaying the information from the camera (68) to control the cooking or defrosting operation.
Claim 12
Dependent Claim 25 words
The method of Claim 11, comprising displaying to a user a representation of the infra-red image, whereby the user controls the cooking or defrosting operation.
Claim 13
Dependent Claim 24 words
The method of Claim 11, wherein the processor (24) controls the cooking or defrosting operation by acting upon information received from the camera (68).
