Definitions
- the present invention relates to a microwave oven with turntable.
- a microwave oven typically includes a compartment serving as a processing enclosure and a compartment for housing a magnetron microwave production system.
- the microwaves produced by the production system are brought by a waveguide into the processing enclosure where an article or food product subjected to a cooking or reheating or thawing treatment is stored. If this article or food product remains motionless inside this enclosure during this treatment, the microwaves in their standing wave regime in this enclosure cause a non-uniform treatment in the mass of this article or product in other words in the mass of this article or food product there are more cooked areas or well reheated or properly thawed which alternate with less cooked areas or still cold or poorly thawed. To make this treatment uniform throughout the article or food product, several solutions have been proposed.
- One of these known solutions consists in mounting in the oven at the outlet of a waveguide, a microwave stirring device in order to obtain a complex regime of standing microwave waves in the enclosure of treatment. This solution brings an improvement in the result obtained but the treatment is still far from uniform throughout the mass of the article or product subjected to this treatment.
- Another known solution provides in the oven treatment enclosure, a turntable with a fixed concentric axis of rotation, the axis being coincident with the center of the tray, to receive an article or product subjected to treatment. During this treatment, the turntable with concentric axis of rotation makes it possible to continuously change the position of the article or product in the enclosure by presenting it to the microwaves.
- the present invention aims to avoid the drawbacks of the known solutions mentioned above and makes it possible to produce a microwave oven, economical and efficient, giving uniform treatment throughout the entire mass of the article or product subjected to treatment. in his precinct.
- the present invention relates to a microwave oven according to claim 1 or 3.
- a microwave oven 1 according to the exemplary embodiment illustrated in FIG. 1, comprises two compartments 2, 3, a compartment 2 intended to house a microwave production system not shown and a compartment 3 serving as enclosure treatment.
- the compartment 3 is closed by a door 5.
- the microwaves produced by the system housed in the compartment 2 are brought into the treatment enclosure 3 by a waveguide not shown.
- the microwaves maintain a steady wave regime there, penetrate the articles or food products stored in this enclosure 3 and carry out a cooking, reheating or thawing treatment.
- a microwave oven comprises in its treatment enclosure as a turntable, a tray which receives articles or products subjected to a treatment and realizes during this treatment a setting in motion of these articles or products according to a circular path in this treatment enclosure.
- the microwave oven 1 comprises in its treatment enclosure 3 as a turntable, a horizontal tray rotating around the vertical axis 10 corresponding to the center of the tray.
- the oven comprises a fixed and vertical axis inside the enclosure eccentric with respect to the center of the plate, said vertical axis of the plate being simultaneously driven in rotation around the vertical fixed axis of the furnace.
- the microwave oven 1 comprises in the treatment enclosure 3 on the one hand a horizontal hollow circular fixed base 11 and a movable driving disc 12, mounted rotatably concentrically to this bottom in a central opening of the latter, around a vertical axis 13 and provided on the periphery of its upper surface, with a circular wiper with a high coefficient of friction 14, and on the other hand as a turntable, a free tray 15 with rim circular 16 placed, free of any attachment, in the horizontal hollow circular fixed base 11 and straddling this movable driving disc 12.
- the microwave oven 1 comprises in the treatment enclosure 3 on the one hand, as a rotating plate a circular horizontal plate 20 rotating around a vertical axis concentric 21, mounted freely in movement on this vertical axis 21 and provided on the periphery of its circular lower surface, with at least three castors with horizontal axis of rotation 24, angularly spaced and aligned on a circular line, and on the other hand , on the bottom wall 27 of this enclosure 3, a circular track 29 for rollers 24, concentric with the vertical axis of rotation 21 of the circular horizontal plate 20, having a diameter equal to that of the circular line of alignment of these rollers 24 and formed of an alternating succession of a number of angularly spaced bosses 30 and recesses 31 which is the same number or a multiple of the number of these rollers s 24 of tray 20.
- the horizontal plate 20 oscillates vertically between its maximum high position represented in solid lines and its maximum low position represented in broken lines in FIG. 4.
- the path of the articles or products carried by this plate 20 is a non-circular path forming a left curve in space.
- rollers 24 of the plate 20 and the circular track 29 are replaced by an equivalent system with cams and cam followers or an equivalent system with screws, of a known type, allowing this plate 20 to rotate around a vertical axis and oscillate simultaneously along this axis.
- the cooking, heating or defrosting of an article or product in the treatment chamber 3 of the microwave oven 1 is advantageously uniform throughout the mass of this article or product.
