Abstract
Abstract of the Disclosure The specification discloses a twin baking oven having two ovens located one above the other in a common housing.
The controls for the ovens are located in the upper part of the housing above the upper oven. Air ducts are pro-vided between the ovens and the housing in order to draw in cool air at the bottom of the housing and to exhaust it at the top. In order to protect the oven controls from overheating, the lower oven is thermally shielded by means of shielding plates from the cooling air ducts and the cooling air passes around the controls before being ex-hausted from the housing. The upper oven is preferably a microwave oven. In this way electrical or electronic control may be used for the oven without being subjected to damage by heat.

Description
:`~
This invention relates to a twin baking oven, partic-ularly of the flush-mounted type, including two baking ovens disposed one above the other and surrounded by a common housing. More specifically, the invention relates to a combination baking oven in which one of the two baking ovens is a microwave baking oven.
In a known baking oven two baking ovens adapted to be heated by conventional heating means and disposed one above the other are accommodated in a common housing.
Disposed above the upper baking oven is an exhausting device adapted to aspirate the heated air flowing upwardly from the two baking ovens and to discharge the heated air to the exterior of the oven arrangement. In view of the fact that the heat generated during operation of the baking ovens is permitted freely to rise within the common housing, there is a risk that heat may accumulate in the upper part of the housing and may interfere with the pro-per operation of the switching and control means located in just that part of the housing.
It is known to provide air ducts between the baking chamber proper and an outer housing, with the lower part of the housing being provided with cooling air inlet apertures and with the upper part of the housing being provided with a blower, the discharge port of which communicates with a substantially enclosed discharge duct leading to the exterior of the oven. It has now been found that, while in a single baking oven it is sufficient to provide such an arrangement of cooling air ducts, such an arrangement does not meet the :.
, - 2 -.~
: requirements of a twin baking oven having two ovens dis-posed one above the other, wherein the amounts of heat developed by the two baking ovens are cumulative so that heat accumulates in the upper part of the housing which conventionally contains the electric or electronic switching and control means. The accumulated heat may thus interfere with the proper operation of such means, particularly when 'che controls are electronic.
It is a primary object of this invention to provide a twin baking oven of the aforementioned type which is constructed in such a way that the occurrence of high temperatures in the upper part of the housing is avoided in view of the limited resistance to elevated temperatures of electric or electronic control means.
According to the invention there is provided a twin baking oven comprising two ovens disposed one above the other enclosed in a common housing, operating means for the ovens located in an upper part of the housing above the upper oven which is a microwave oven, top, side, bottom and rear walls covering said twin baking oven, with apertures being formed in at least one of the side and rear walls at a location correspondillg to the lower portion of said uppcr oven, cooling air ducts having an inlet at a lower part of the housing and an outlet at an uyper part of thc housing, and thermal shielding mealls located between said lower oven and said upper oven for thermally shielding the lowel oven from the cooling air (lucts, the cooling air being almulllged to ellter said inlct and to pass between said bottom wall and a lower inner surface of the housing and between said rcar wall or said side walls and side or rear `
inncr surf;lcc of the housing, througll said .apertures and - along all air duct constituted ~y walls of the upper oven and Or the housing to flow past said operating means and be discharge.l ~rom sa-id outlet.
Preferably, a blower is provided to assist the air flow.
l'he specific manner in which the air flow is con-; trolled, in conjunction with a suitable arrangement of the inlet and outlet apertures, makes it possible for . 10 the cooling air drawn in at the bottom of the housing substantially to bypass the lower baking oven and to flow, at a relatively low temperature, to the upper part of the housing so as positively to prevent any excessive heating of the control and regulating means disposed in said upper part of the housing. This feature is of particular impor-tance when electronic components are employed in the control means which should not be subjected to ambient temperatures of more than about 70 degrees centigrade.

baking chamber of the upper oven communicates with said duct, the arrangement being such that the main air stream produced by the blower exerts a suction effect on the waste air leaving the baking chamber so as to enhance the discharge of said waste air.
In a particularly advantageous embodiment of the invention, a frame is provided comprising side and rear walls forming said shielding plates associated with the bottom part of the housing, said frame having the lower oven attached thereto and being provided, in its upper portions with guide rails permitting the microwave ove to be slid into the frame as a self-contained unit, the microwave oven being adapted to be locked in position with the aid of securing means which are preferably adjustable. This arrangement makes it possible in a particularly simple and economical manner to manufacture the microwave oven separately as an independent unit and to insert said unit into the housing with a small number of manipulations, the adjustability of said securing means permitting the front surfaces of the two ovens to be accurately aligned.
The invention may be carried into practice in a number of ways but a specific embodiment will now be described by way of example with reference to the accompanying drawings, in which:-Fig. 1 shows a twin baking oven according to oneembodiment of the invention in a vertical cross section on the line I-I of Fig. 2;
Fig. 2 is a plan view of the twin baking oven of Fig. 1 with the top panel and some parts removed; and Fig. 3 is a front elevational view of the twin baking s.~;s~,.
oven showing the front panel thereof in the left-hand half and the parts lying behind the front panel in the right-hand half.
The twin baking oven shown in the drawings is mounted in a housing preferably in the form of a piece of fur-niture including, for example, panels made of wood, comprising side panels 1 and 2, a cover panel 3 and a bottom panel 4, the piece of furniture thus defining a space which is adapted to receive the twin baking oven.
Reference numeral 5 denotes a kitchen wall in abutment with which the oven unit is disposed and which conse-quently forms part of the housing for the twin oven.
As shown in ~ig~ 1, the external surfaces of the twin baking oven mounted within the housing are formed by opposed side walls 6 and 7, a rear wall 8, a lower shielding plate 9 and an upper cover member 10. Mounted in this frame formed by the members just mentioned is a lower baking oven 11 which includes a front-side down-wardly pivotable door 12 provided with a glass window 13 and a handle 14 and which ~urther includes conventional heating elements, e.g. a grilling (broiling) heater 15 as well as additional upper and lower heating elements.
An upper baking oven 16 is also provided and is constructed as a microwave oven comprising a baking chamber 17, a microwave generator, a microwave guide and a microwave antenna, e.g. a magnetron 18, a ~ se known air-driven fiel~l agitator 19 disposed within a dielectric cover 20, a rotary table 21 and the like and provided, at its front side, with a downwardly pivotable door 22 fitted with a glass window 23 and a handle 14.
The microwave oven 16 is provided with a ventilating .
system of its own which includes a blower 24, an air duct 25 which houses the magnetron or its cooling surfaces, air supply apertures 26 and outlet apertures 27 in the rear wall of the baking chamber, and an L-shaped waste air shaft 28 of rectangular cross section secured to the rear wall of the baking chamber. As indicated at 29, both ovens are externally provided with heat insulating layers.
The lower oven 11 is secured to rear wall 8 and side walls 6, 7 through oven holders 30 and baking chamber 10 brackets 31, respectively. Microwave oven 16 is similarly held in position by baking chamber brackets 31 attached to side walls 6 and 7, rearwardly disposed oven holders 30 and through horizontal sliding rails 32 secured to members 30 and 31 on both sides of oven 16 and permitting the microwave oven 16, as a complete unit, to be slid into position in the upper cavity of said housing on supporting angle sections 33 and to be locked in position. In order to provide for exactly coplanar alignment of the two glass windows 13 and 23 of the two ovens 11 and 16, the support-20 ing angle sections 33 are connected to oven 16 by means ofadjustable pin and slot arrangements, and said supporting ~r angle sections 33 are similarly adapted, e.g. by means of screws, to be adjusted in relation to their associated sliding rails 32 or together therewith and to be locked in the desired position.
Electrical or electronic controls 34 are accommodated in a housing cavity above upper oven 16 for regulating and operating the two ovens. The under side of cover 10 defining the top of the twin baking oven has an exhaust 30 duct 35 attached thereto having two opposed open ends, one of said open ends communicating at the front of oven 16 with upwardly directed exhaust apertures 36, the other open end of the exhaust duct communicating with the delivery port of a blower 37 also mounted on the under side of cover 10. Exhaust duct 35 is provided with a further aperture 38 which communicates with the free upper end of waste air shaft 28 of microwave oven 16 after cover 10 has been positioned on the housing containing the aforementioned components.
The twin baking oven is provided on its front side with an external peripheral trimming or strengthening strip 39 having a predetermined cross-sectional shape which partially extends over the furniture panels. The lower horizontal portion of the strip is provided with cooling air inlet apertures 41, and the upper horizontal portion of the strip is provided with the outlet apertures 36 mentioned earlier.
As shown in Fig. 1, the lower shielding plate 9 is disposed immediately below the lower oven 11 or its heat insulating layer, and the lower oven 11 is also addition-ally surrounded by side walls 6, 7, rear wall 8, and ashielding plate 42 (similar to plate 9) disposed immed-iately above oven 11, said shielding plates being made, for example, of sheet steel. This outer housing of the lower oven is spaced in such a manner from the inner surfaces of the furniture panels as to form, at the periphery of the housing, cooling air ducts 43, 44 and 45 which, while being in communication with one another, are isolated from lower oven 11 and thermally separated therefrom by the shielding plates and the side and rear walls. It is only above upper shielding plate 42 that rear wall 8 and side walls 6, 7 are provided with s~
apertures 47 and 46, respectively, which permit cooling air to enter into the cavity containing the upper oven 16 and into ventilating space 48. Thus, cooling air drawn in through inlet apertures 41 will enter the cooling air ducts 45, 44 and 43, it will be bypassed around the lower oven 11, it will rise under the influence of natural con-vection and of the suction effect of blower 37, it will then flow through ventilating space 48 and past the control ; and regulating means, it will be directed from the suction side of blower 37 to exhaust duct 35 and finally dis-charged to the exterior of the oven unit. Due to this arrangement, the forced air stream exerts a suction effect on waste air shaft 28 to enhance the discharge of waste air from the baking chamber of oven 16.
