Definitions

  • N device for terminating cooking and indicating status.
  • the invention relates to a device for terminating cooking and indicating the status in an oven for the preparation of food comprising an oven cavity and an oven door.
  • Ovens which are set by a timer to a finishing time are well known and they exist in simple user-set versions or in more elaborate versions where the finishing time is calculated internally in the oven control circuitry, e.g. by measured parameters.
  • Simple ovens may be set to switch-off the power supply at the finishing time, and more elaborate ovens may calculate the remaining heat in the oven and perform the switching-off before the actual finishing time.
  • the parameters measures may be temperature, humidity or composition of fumes developed within the cavity, and advanced data processing may be used in order to determine the development of cooking in each particular instance.
  • the known methods are not suitable for all cooking/baking, in particular for food which is designed to be taken out of the hot cavity at the correct instant. In such cases, it is not a question of programming the oven to switch off but to programme the user to act, either at a given time or when a specific condition of done-ness has been established in the oven.
  • the reaction of a user - or the non-reaction, as the case may be - is an impredictable parameter, and hence known ovens do not give the impression of functioning properly at all times. Simply put, if the user forgets to take the food out of the oven at the correct time, it will be overcooked. There is hence a need to provide technical means to minimise the consequences of lack of user cooperation. There is a further need to communicate to the user by other means than the activation of a sounder, such as the ringing of a bell.
  • the primary opening of the door is only partial. This has the advantage of preserving child safety, preventing access to the escaping steam and fumes. Such a positive partial opening may be followed by a full opening after an optional cooling-ofF period.
  • the opening of the door is accompanied by a turning on of the oven cavity light. This provides a further indication of the action of the oven door, in that the presence of a cloud of steam will be advertised by light from behind.
  • the oven door and oven cavity light are linked such that any manual closure or opening of the oven door causes a gradual change in light intensity from full light to dark and from dark to full light respectively, whereas a cooking status triggered door operation causes a sudden light intensity change.
  • the user will perceive the calm and confident handling of the food by the automatic oven when operating it, while being rudely advertised of the finishing time by the instant presence of light and steam and fumes.
  • a further embodiment is particular in that the triggering of the door opening is obtained by means of signals from smoke detecting means. This has the added advantage that an erroneous adjustment of the cooking parameters at the initiation of cooking will not result in charred food, because the door opens and the oven switches off. As a minimum result of this provision, the need for cleaning of the cooking vessels and oven are simplified, and there is an increased chance of re- cooking and obtaining useful cooked food in spite of the original erroneous adjustment.
  • a further embodiment is particular in that the triggering of the door opening is obtained by means of signals representative of a reduction of the amount of steam developed over time This feature is food dependent and would represent e g cakes and bread
  • the fundamental aspect of the invention is the combination of creating a fast normalisation of the cooked food with advertising that it is finished This is brought about by the means defined in the claims
  • a further aspect is that of safety, in particular for children, when a kitchen appliance which stores a large amount of thermal energy, suddenly releases it Hence the provision of a gradual opening of the door in order to prevent children from obtaining direct access to large areas of hot surface
  • the triggeiing of the door release is obtained by a signal which represents that cooking has finished, and a number of signals may be used to this end
  • the door will not only be released, but it will be opened positively, i e by means of the release of energy stored in a spring or by means of a motor
  • the latter is the choice when the door is actually made like the front of a drawer which slides out from the oven
  • Fig 1 shows a spring-loaded door with a trigger device and two-stage opening
  • Fig. 2 shows the cavity light intensity as a function of time and closure, respectively opening, of the oven door in the cases that a manual operation is performed or a triggered operation
  • Fig 1 an oven door which is closed shut against a spring force as a storage device, or a motor creating a suitable resistance
  • the oven door 1 is closed against the cavity 2 when it is at 0° opening angle
  • the spring arrangement 3 acts on a lever 5 at the bottom of the door (however, many practical, similar embodiments are possible) in order to open it against the resistance of the dashpot 6
  • the oven door is indicated in 3 positions 0°, 15°, and fully open at 90°
  • the position of the door is linked to the level of light emitted by a suitably fitted lamp 7.
  • a blower is connected to the space S and may through openings 8 blow a stream of air along the oven door 1 to draw fumes out and to cool the door when it is in the limited opening position at 15°.
  • a humidity sensor 9 is connected to the control electronics 10 which in turn controls the blower and release means for the door C.
  • the light may be set to flash at an assureent rate, at least for the time that the oven door is only partly open, and changing for a stable light when the oven door is manually activated in order to remove the cooked food.
  • Fig. 2 shows in right-hand part of Fig. 2, in which it is seen that for the chosen opening angle of the oven door, in casu 15 °, the light flashes insistently until the time t ⁇ , whereupon it changes to normal combined opening and light change.
  • a blower fitted into the oven door drive compartment blows cooling air taking from outside the oven cavity over the inside of the door as well as carrying the smell of finished food into the living quarters.

Abstract

On peut déterminer la fin de la cuisson au four au moyen de préréglages ou par mesure de paramètres appropriés. La fin de la cuisson déclenche l'ouverture automatique de la porte du four afin d'indiquer l'état dudit four. Lorsque l'ouverture de la porte est automatique, elle peut s'associer à un changement soudain de l'intensité de la lumière dans le four, alors qu'une ouverture ou une fermeture manuelle provoque l'extinction ou l'allumage progressif de ladite lumière. L'ouverture partielle du four lors du signal de fin de cuisson et sa mise à l'air libre sont accompagnées d'éclairs de lumière.
