Definitions
- the present invention relates to a household oven comprising a housing provided with feet and in which are mounted a cooking enclosure and heating means controlled by means of programming the cooking operation.
- the invention relates in particular, but not exclusively, to an oven of the microwave oven type, the cooking chamber of which comprises a turntable driven in rotation by an electric motor during the cooking operation. It relates more particularly to a device for weighing food integrated in the oven.
- the object of the invention is to provide a weighing device for a cooking oven which does not have these drawbacks and which is particularly practical to use.
- a further object of the invention is to obtain a return the turntable to its starting position after a cooking operation, using elements of the weighing device.
- the oven comprises sensors arranged in each of the legs of the housing and adapted to respectively deliver an electrical signal representative of the weight supported by each leg, means for determining the total weight from the signals received from the sensors, means calculating the weight of the food from the total weight, as well as means capable of transmitting the weight of the food to a display and / or to the programming means.
- the sensors are no longer arranged close to the cooking chamber, which eliminates the problems of space in the housing and heat resistance of the sensors.
- This weighing device can easily be integrated into an oven without having to modify its structure. It is possible to use common and inexpensive type sensors such as strain gauges arranged on a deformable bar. In addition, this device makes it possible to weigh food placed in the cooking chamber, but it also makes it possible to weigh food placed on the upper face of the housing. This makes its use as practical as a kitchen scale.
- the oven comprises means for controlling the motor connected to the programming means of the oven and to at least one of the sensors.
- control means include means for memorization capable of memorizing the weight indication delivered by the sensor before the rotation of the tray and are capable of stopping the rotation of the tray, after the programmed cooking time, when the weight indication delivered by said sensor corresponds to the stored indication.
- the tray control means will be able to stop the tray in its starting position thanks to the weight indication. delivered by the sensor.
- FIG. 1 is a front view of an oven comprising a weighing device according to the invention
- - Figure 2 is a detailed view in vertical section of a foot of the oven shown in Figure 1;
- FIG. 3 is a schematic representation of the various elements used to realize one invention.
- FIG. 1 there is shown a household oven comprising a housing 1 provided with feet 2 and in which are mounted a cooking chamber 3 and heating means (4,5) controlled by programming means 6 of the operation Cooking.
- the oven shown has four feet, but it could only have three feet while maintaining good stability.
- the heating means comprise an electric heating resistance 4 and a microwave generator 5 of the magnetron type, the energy of which is delivered in the enclosure 3 by means of a waveguide 7.
- the invention is applicable to an oven comprising only one of these heating means.
- the oven is provided with a door, not shown, allowing food to be introduced into the cooking chamber 3. Only the hinges (8, 9) and the locking orifice 10 of the door hook are visible. in FIG. 1.
- the programming means 6 make it possible to control the operating parameters of the oven, such as the duration and the operating power of the heating means (4,5). These parameters can be chosen by the user by positioning the control buttons (11,12) next to the corresponding pictograms. However, as described below, the cooking parameters can be determined differently. Key 13 allows you to start a cooking operation.
- the oven comprises sensors 15 arranged in each of the legs 2 of the housing 1 and adapted to respectively deliver an electrical signal representative of the weight supported by each leg 2, means 16 for determining the total weight from the signals received sensors 15, means 17 for calculating the weight of the food from the total weight, as well as means 18 capable of transmitting the weight of the food to a display 19 and / or to the programming means 6.
- weight sensors are used, as shown in FIG. 2, comprising a strain gauge 21 arranged on a deformable bar 22, one end 23 of which is integral with the housing 1 of the furnace and the other end 24 of which is integral with the lower part 25 of the base 2 in which the sensor 15 is arranged.
- the deformable bar is secured to the housing by an intermediate plate 26.
- This type of sensor gives reliable indications over a large weight range and is not very sensitive to electromagnetic disturbances.
- the foot 2 and the sensor 15 are arranged in a protective cover 27 in the shape of a bell leaving the lower part 25 of the foot protruding.
- the sensors 15 deliver a signal representative of the weight supported by each of the feet 2 to the means for determining the total weight 16.
- the means for determining the weight, total 16 perform a summation of the signals received by means of an electrical circuit connecting the strain gauges 21 in the form of a Wheastone bridge which supplies a voltage proportional to the total weight.
- the means for determining the total weight 16 then process the signal before transmitting it to the means 17 for calculating the weight of the food.
- this treatment consists in amplifying the voltage supplied by the Wheastone bridge, then in transforming this voltage by a voltage / frequency converter circuit. But of course, it is possible to first of all process the signals received from the sensors, for example an analog / digital conversion, then a summation of these signals to obtain the total weight supported by the feet of the oven.
- the means for calculating the weight of the food 17 must be able to calculate the weight of the food from the total weight supported by the feet of the oven.
- the calculation means 17 may include a permanent memory in which is entered, during its manufacture, the weight of the vacuum oven and subtract this stored value from the total weight of the oven.
- This solution is not entirely satisfactory. On the one hand there may be variations in weight from one appliance to another and variations in the signals delivered by the weight sensors which could lead to the calculation of a non-zero weight when the oven is empty. On the other hand, this solution does not take into account the weight of the dish containing the food or any object placed on the " upper side 28 of the oven housing.
- the means for calculating the weight of food 17 thus comprise means for calibration 30 may be implemented in one actuation of a key 31.
- a key 31 provision, user, after placing the empty dish, can press the taring key to zero the calculation of the weight of the food.
- This taring operation is easily controlled using the display 19 which continuously indicates the weight of the food weighed by the oven.
- the calculated weight corresponds exactly to the net weight of the food. It is important to note that, thanks to the arrangement of the sensors according to the invention, it is not necessary to systematically place the food in the cooking chamber, the taring and weighing operations can be carried out by simply placing the food on the front upper housing 28. This even allows the oven to be used as a traditional household scale.
- the weight of the food thus calculated can be transmitted to the programming means 6 of the cooking operation.
- the programming means 6 are capable of determining the cooking parameters as a function of the weight of the food and of at least one parameter linked to the nature of the food. This last parameter is selected by the user using button 12 which in the embodiment shown makes it possible to select a food, either of the fish type, or of the roasted meat type, or of the pizza type.
- this list can be more extensive and it is possible to multiply the number of parameters, in particular to take into account the type of cooking to be carried out (thawing or reheating) or the desired result (rare or medium).
- the programming means are able, on the basis of these parameters and of stored algorithms, to control the time and the operating power of the various heating means (4,5). This arrangement simplifies the use of the oven and ensures the user an optimal result.
- the means 17 for calculating the weight of the food comprise, in addition to the taring means 30, means for subtracting 32 from the weight of a container comprising storage means associating for different types of containers a characteristic weight and means 11 for selecting a type of container, said means for subtracting 32 from the weight of a container being able to subtract from the calculated weight the characteristic weight of the type of container selected.
- the user is no longer obliged to place the empty container in the oven for each tare to use. It is sufficient, after placing the food in its dish, to position the selection button 11 opposite the type of container used, the subtraction means 32 then subtracting the corresponding pre-stored weight.
- the selection means 11 make it possible to choose a container, either of the cup type, or of the plate type, or of the dish type.
- the characteristic weight of each of these types of containers can be definitively entered in the storage means during the manufacture of the oven.
- the means for subtracting 32 from the weight of a container comprise means for recording the characteristic weight of a type of container allowing, during the activation of a memory key 33, to assign to the type of container selected the weight calculated before subtraction. This limits the number of taring operations of the weighing device while retaining an accurate measurement of the weight of the food.
- the means for subtracting 32 from the weight of a container comprise an algorithm capable of determining a value representative of the weight of the container from the weight calculated by the taring means and of subtracting from this calculated weight said value representative of the weight of the container.
- This algorithm can be performed in different ways. For example, if we consider that the weight of the container is proportional to the weight of the whole food plus container, the algorithm can consist in subtracting a fraction of the calculated weight. One can also consider that if the calculated weight is within a certain range of values, using a certain type 'container having a weight characteristic. This method of subtracting the weight of a container is particularly practical since it does not require any intervention by the user.
- the calculated weight of the food may be slightly different from the actual weight, but experience shows that this value is close enough to the actual weight for the programming means to determine cooking parameters giving a completely satisfactory result.
- the means 17 for calculating the weight of the food comprising both the taring means 30 and the means 32 for subtracting the weight of a container, as well as the means 18 for transmitting the calculated weight and the programming means 6 for oven can be realized by a single programmable microcontroller of type 8 or 16 bits.
- the cooking chamber 3 of which comprises a turntable 36 driven in rotation by an electric motor
- said oven comprises control means
- control means 38 of the motor 37 connected to the programming means 6 of the cooking operation and to at least one of the sensors 15.
- These control means 38 include memory means capable of memorizing the weight indication delivered by the sensor 15 before the rotation of the plate 36, and capable of stopping the rotation of the plate 36, after the programmed cooking time, when the weight indication delivered by said sensor 15 corresponds to the stored indication.
- the control means 38 will be able to stop, after cooking, the rotation of the tray in its initial starting position, thanks to the weight indication delivered by the sensor 15.
- a dish placed eccentrically on the turntable causes a variation in the weight supported by the different feet during the rotation of the tray.
- the control means 38 can store the weight indications delivered by two sensors 15. But more advantageously, the storage means of the control means 38 store, in addition to the weight indication delivered by one of the sensors 15 before the rotation of the plate 36, the rate of change of this weight indication at the start of the rotation of the plate 36, the control means 38 of the motor 37 being able to stop the rotation of the plate 36 when the sensor delivers both an indication of weight and a rate of change of this indication corresponding to the indication and the rate, memorized.
- the weight of the food decreases during the cooking process.
- the weight indication delivered by a sensor 15 at the end of cooking will never be equal to that given at the start of cooking. It is therefore advantageous for the control means 38 of the motor 37 to comprise means capable of taking into account the variation in the total weight supported by the feet 2 in order to compare the stored weight indication and the weight indication delivered at the end of the programmed cooking time.
- the weight indication stored at the start of cooking can be divided by the total weight of the oven at that time. Then at the end of cooking the control means 38 compare the weight indication divided by the total weight of the oven with the stored value.
- This function of returning the platform to the initial position does not represent a significant additional cost since it uses the signal from a sensor of the weighing device and the control means 38 of the motor 37 of the platform. turn 36 are integrated into the microcontroller already used for the weighing device.
- the invention responds to the concern of making a practical and expensive weighing device making it possible to increase the automation of cooking. It also allows the oven to be used as a kitchen scale by placing the food on the upper side of the housing. In addition, the main elements of the weighing device make it possible to control a return of the turntable to the initial position without using additional sensors.
