Definitions

the present invention relates to a microwave oven comprising a cavity intended to receive at least a particular type of container containing a solid food or liquid to be heated, a generation device of microwave energy which is powered by a circuit power supply, a control panel which includes means allowing, on the one hand, to select the particular type of container among a plurality of predefined and identified container types each on the control panel by a particular symbol identification, and secondly, to trigger a reheating phase of the food, storage means the duration of the reheating phase following the type of particular container selected, and means automatic control system comprising the storage means and enabling the supply circuit electric from the information contained in the means of memorization.
means for selecting the type of particular container and to initiate the reheating phase, the duration of which is predetermined according to the type of container selected consist of a single arranged push button on the front of the control panel, while the automatic control means activate the supply circuit electric in response to a number of presses exercised by the user on this push button, which number of presses is different for each type of container being predetermined according to the type of selected container.
Such a microwave oven equipped with a single push button for automatic triggering of the reheating phase of different types of containers is currently fully satisfactory.
the reheating temperature is imposed for each type of selected container, thus constituting a constraint for the user when he wishes, in according to its taste, reheat the container to a temperature greater than that imposed on it.
the invention therefore proposes to improve in a simple way this microwave oven, of the exposed type above, by offering the user the choice of reheating temperature of different types of containers that best suits his taste.
the selection and triggering means include a plurality of operating buttons, in number equal to that of the predefined container types, arranged on the front of the control panel and each identified by the particular identification symbol, that each button also constitutes a button allowing to select, before initiation of the reheating phase, a particular level of reheating temperature among several predefined temperature levels, and that the storage means contain, for each type of the particular container selected, the duration of the reheating phase which is predetermined according to the particular temperature level selected using the corresponding button.
the microwave oven has a cavity 1 intended to receive, on a turntable 2, at least one type of container particular, in this case only one, containing solid or liquid food to be reheated, as presently a bowl of milk 4, and a supply circuit electric 6 which feeds from an energy source electric (not shown) of nominal power data, a microwave energy generation device, namely a magnetron 7, and possibly a heating resistor 9 placed inside the cavity 1.
a microwave energy generation device namely a magnetron 7, and possibly a heating resistor 9 placed inside the cavity 1.
the microwave oven includes a housing 11 provided on the front face 12 with a door articulated 14 delimiting the cavity 1, and a table of control 16 arranged on the right side of the front face 12 of the housing 11.
control panel 16 comprises means 18 allowing, on the one hand, to select the particular type of container from a plurality of predefined container types, in this case three such as a cup, a bowl and a plate, and identified respectively on the front of the control panel 16 with special symbols of identification, in this case three identification symbols 20, 21 and 22 representing a cup, a bowl and a plate, and secondly, to trigger a phase of automatic reheating of the type of container selected.
a plurality of predefined container types in this case three such as a cup, a bowl and a plate
special symbols of identification in this case three identification symbols 20, 21 and 22 representing a cup, a bowl and a plate
the control panel 16 further comprises, as shown schematically in Figure 4, means 24 memorizing the duration of the reheating phase depending on the type of container selected, and means automatic control 26 comprising the storage means 24 and enabling the supply circuit electric 6 of the magnetron from the information contained in these storage means 24.
the selection and trigger means 18 comprise a plurality of identical operating buttons, in a number equal to that of the types of containers, in this case three in number designated respectively by the references 28, 29 and 30 in Figures 2, 3 and 4 and each consisting of a push button, which are grouped on the front of the control panel 16 and which are each identified by the particular identification symbol 20; 21; 22.
the push button 28 is identified by the symbol 20 representing the cup
the push button 29 is identified by the symbol 21 representing the bowl
the push button 30 is , meanwhile, identified by the symbol 22 representing the plate.
each push button 28; 29; 30 also constitutes a button making it possible to select, before triggering of the reheating phase, a particular level of reheating temperature from among several predefined temperature levels, for example two in number, which are identified respectively by two symbols 33, 34 marked with front of the control panel 16, for example below and near the three symbols for identifying the types of receptacles 20; 21; 22 (see FIG. 3), and which correspond respectively to a first reheating temperature, denoted T 1 on the symbol 33 in FIG. 3, for which the food is qualified as hot, and to a second reheating temperature, denoted T 2 on symbol 34 in Figure 3, and for which the food is classified as very hot.
T 1 first reheating temperature
T 2 second reheating temperature
a cup or a bowl containing any liquid is qualified as hot for a reheating temperature T 1 equal to 65 ° C, and very hot for a reheating temperature T 2 equal to 75 ° C; a plate of soup is classified as hot for a reheating temperature T 1 equal to 60 ° C, and very hot for a reheating temperature T 2 equal to 70 ° C.
each of the two reheating temperature levels is selected by a number of predefined presses exerted by the user on the same button 28; 29; 30 for selecting the type of container; for example, a single press on the button 28; 29; 30 selects the first temperature level T 1 (hot), while two successive presses on this same button 28; 29; 30 select the second temperature level T 2 (very hot).
the means 24 for memorizing the duration of the reheating phase, FIG. 4, contain, for each type of selected container 20; 21; 22 (FIG. 3), the reheating time d which is predetermined as a function of the particular temperature level T 1 ; T 2 selected by pressing (s) using the corresponding button 28; 29; 30.
the reheating time d is equal to 45 seconds for a hot cup, and 55 seconds for a very hot cup; for a hot bowl, the duration d is equal to 1 minute and 40 seconds, and for a very hot bowl, this duration d is equal to 2 minutes and 10 seconds; the duration d is equal to 2 minutes and 30 seconds for a plate of hot soup, and to 2 minutes and 50 seconds for a plate of very hot soup.
control panel 16 (FIG. 2) has on the front face a display means 36 connected to the control means 26 and intended to display the duration d of the reheating phase during the first or second pressing the button 28; 29; 30.
the user presses once the button 29 identified by the symbol 21 representing a bowl, thus selecting the type of container and the desired temperature level T 1 (hot).
the button 29 is pressed, the corresponding reheating time d , determined using the automatic control means 26, and in this case equal to 1 minute and 40 seconds, is displayed on the display 36.
the control means 26 then perform a test on the pressing time t 1 of the button 29 with respect to a predetermined time t 0 , in this case equal to 1 second.
the oven does not start.
the oven starts and the control means 26 activate the electrical supply circuit 6 of the magnetron; the reheating phase being thus triggered, the reheating time d written on the display 36 is then counted down, thus making it possible to obtain, at the end of reheating, a bowl of hot milk.
the corresponding reheating time d is written on the display 36.
control means 26 then perform a test on the pressing time t 2 of the button 29 with respect to the predetermined time t 0 equal to 1 second.
a third press, if any, exerted on the button 29 is considered to be a first press to select the temperature level T 1 ( hot).
the oven starts and the control means 26 activate the electrical supply circuit 6 of the magnetron; the reheating phase being thus triggered, the reheating time d written on the display 36 is then counted down, thus making it possible to obtain, at the end of reheating, a bowl of very hot milk.
