DRAWER-TYPE HYBRID COOKING APPLIANCE WITH SELECTIVE AIR RECIRCULATION, BOTTOM THERMAL CARTRIDGE AND KINEMATIC STEAM VALVE.

Abstract

The invention relates to a hybrid cooking appliance that combines the upper hot air cooking compartment, located between the separating manifold and the airtight grill-lid (31), with the removable liquid cooking chamber (42) at the bottom, in the same drawer architecture. The grill-lid (31) seals the glass chamber (42), allowing the food above to be cooked and transferring heat to the chamber from above. The technical compartment, containing the fan (21) and heater (22), is separated from the cooking return air by an airtight directing manifold (62) that extends along the depth of the appliance. Heated fresh air is transferred only to the left supply duct (50); it is distributed via the left directing (126) to the parallel closed passages of the removable lower thermal cartridge. The heat transfer fins (52), the upper heat transfer plate (122), and the lower closing plate (124) in the cartridge provide a large surface area heat transfer to the bottom of the chamber.Air is raised through the right-hand guide (128) to the L-shaped right module (114) and delivered to the upper cooking chamber by a selective mechanism, either entirely to the exhaust or distributed in variable proportions between the upper cooking and exhaust. The steam nipple connected to the chamber (42) is centered in the valve inlet seat (70) by being lifted up along the kinematic route (185) in the final section of the drawer closing. The disc flap (175) inside the valve directs the steam to the injection channel (72) or the discharge path (71); the mechanical pressure relief element (178) containing a spring and ball opens a safety relief connection independent of the normal operating valve, ensuring pressure safety.

It relates to controlled humidity and vapor management. Specifically, the invention concerns a separator manifold with a sealed grid cover. the upper hot air cooking chamber located between them and the liquid cooking chamber located below it are the same In a drawer-style architecture, it operates together; separating the fan and heater technical compartment from the cooking return air; Removable lower thermal cartridge, upper cooking and exhaust airflows are selectively or proportionally regulated. a hybrid cooking device containing a controlled steam valve kinematically coupled with a mechanism It is related. State of the Art In conventional hot air cooking appliances, the hot air generated by the fan and heater is mostly in a single unit. The liquid is circulated in the upper cooking chamber. In these devices, the liquid, such as rice, soup, or sauce, is in the lower chamber. A large surface area bottom heating element is required for controlled cooking of food simultaneously in a separate chamber. Transfer and steam management are generally absent. Even when different cooking sections are combined in well-known multi-functional cookware, oily and moist surfaces remain unaffected. return air reaching the fan and heater compartment; sudden changes in air cross-section occurring in the airways; bottom Heat applied to the surface is concentrated in a narrow area; air and vapor connections are broken when the drawer is removed. leaving it open; moisture being only constantly vented or being retained inside uncontrollably, for example Problems may be encountered. Additionally, a steam outlet connected to the glass reservoir during drawer movement connects directly to the fixed valve seat. Axial impact can lead to seal wear and stress. Operating valve and mechanical safety. The fact that their functions are not organized independently and understandably within the same flow system also reduces their chances of success. Working under pressure can limit safety. For these reasons, a low-loss air recirculation system that prevents dirty return air from entering the technical compartment is recommended, using a lower window. a large surface area capable of transferring heat to the base of the chamber, and a cooking area on top of the leak-proof grill-lid. providing selectable or variable rate airflow to the exhaust, also at the final stage of drawer closing. An integrated architecture is needed that creates a low-stress steam connection. Purpose of the Invention The main purpose of the invention is to combine top-level hot air cooking with bottom-level liquid or watery cooking in a single drawer. The goal is to create a device that can perform these actions in simultaneous or separate modes. Another objective of the invention is to create a sealed technical compartment containing the fan and heater that extends the entire depth of the device. By separating it from the cooking air with a separator and diverter manifold, it removes oily, smoky and intensely moist air. The purpose is to prevent return air from entering the technical compartment. 35 2 Another purpose of the invention is to deliver clean, hot air only to the left supply channel, inside the lower thermal cartridge. The aim is to ensure even and balanced heat transfer to the glass chamber base by passing the heat through parallel, closed passages. Another objective of the invention is to provide a full-depth L-shaped rotation and distribution module on the right side, with one or more modules. using a flow selector mechanism that includes multiple flow control elements to create an airtight grille cover Selective or variable rate to the cooking area, upper cooking compartment and / or exhaust path It is about directing in a certain way. Another purpose of the invention is to draw the movable steam nipple, attached to the glass reservoir, into a fixed valve inlet seat via a drawer. in the final part of the closing, by seating it with a small vertical upward movement, the connection stroke and seal. The goal is to reduce the strain. Another purpose of the invention is to direct the steam during operation to the upper cooking zone or exhaust channel. a mechanical safety element that responds to pressure at the inlet line with an internal disc valve within the same valve system It means to use them together.

It includes a drawer. The drawer moves on rails (40) on both sides and is double-walled vacuum insulated. It can be surrounded by drawer walls (41). Inside the drawer, there is a removable borosilicate glass container (42). The top of the reservoir is sealed with a grille-lid (31). The grille-lid (31) has a top surface It allows meat, chicken, fish, vegetables and similar foods placed inside to be cooked with forced hot air, and It also transfers heat from above to the glass container (42). The glass container (42) is used to hold liquids such as rice, water, soup, sauce and so on. It is suitable for cooking liquid foods or other liquid dishes. The grille-lid (31) seals the glass container (42) with its gasket, circumferential seating surface and / or locking mechanism. By sealing it in this way, it creates a volume suitable for controlled steam accumulation and low-pressure cooking inside the chamber. It forms the upper cooking section, enclosed between the separating manifold and the airtight grill-lid (31). It is the volume. The grill lid (31) is the upper limit of the pressurized volume inside the glass chamber and the bottom of the upper cooking section. It serves two functions simultaneously as a limiting factor. Working pressure depends on the glass material, chamber geometry, and seal. The locking mechanism is determined by considering the valve and safety element together and assigning a specific numerical value. It is not limited. Fan, Heater and Technical Compartment Separation The fan (21) and heater (22) are placed in the technical compartment of the appliance in series flow relationship. In the preferred arrangement The fan (21) is located first in the flow direction, then the heater (22). The fan-heater axis is inclined according to the device layout. or horizontal. Clean hot air at the fan (21) and heater (22) outlet, fan-heater outlet and return. Air is transferred from the manifold (23) to the left side airflow tunnel (60). The technical compartment and cooking air zone, the upper turn extending along the front-rear depth of the appliance, and directional manifold (61), fan-heater outlet and recirculation manifold (23) and connected seals They are separated by separating surfaces. This separation allows the oily, smoky or dense material rotating from the right side to flow away. Moist air cannot enter directly into the fan (21) and heater (22) compartment. It is pressurized by the fan (21). clean or filtered air from the heater (22) and the fan-heater outlet and recirculation manifold (23) It is passed through and delivered only to the left side airflow tunnel (60). between the top return and redirect manifold (61) and the fan-heater outlet and recirculation manifold (23) A teardrop-shaped flap (180) can be found at the junction. Teardrop-shaped flap (180), fixed flap pivot (182) It moves around; it creates a controlled opening with a C-shaped guide and short seating lip (184). This The structure allows air coming from the top return and steering manifold (61) to pass through the drop-shaped valve (180) 35 Depending on its position, the cooking area on top of the airtight grill-cover (31) or the fan-heater outlet and return directing it to the circulation manifold (23) and sealing it between the technical compartment and the cooking side It ensures the preservation of distinction. Left Feed and Lower Thermal Cartridge Hot air from the left side airflow tunnel (60) is conveyed downwards and to the left fixed inlet located inside the drawer. It reaches its router (126). The router (126) converts the vertical flow to a horizontal flow and the flow to the lower thermal cartridge. It distributes the transitions into parallel passages. The turn and expansion are continuous or gradual, rather than a sudden step. This can be achieved with curved / diffuser geometry. Bottom thermal cartridge; glass reservoir bottom heat transfer plate (114), multiple longitudinal heat transfer fins (52), lower barrier and closing plate (124), left fixed entrance guide (126) and right fixed turn and Includes the rise guide (128). The glass chamber bottom heat transfer plate (114) flat glass chamber (42) Fins (52), either make contact with the base over a large surface area or transfer heat through a small conduction gap. The glass chamber is in thermal contact with the heat transfer plate (114) and has both the air contact area and the plate. It increases heat distribution throughout. In the preferred application, eight wings (52) are used and seven parallel closed air passages are placed between the wings. is formed. The first and eighth wings form the front and rear air boundaries of the cartridge. Air The alignment of the envelope is based on the inner surfaces of the first and eighth wings facing the air passages. The outer surfaces of these wings are on the front and rear edges of the glass chamber bottom heat transfer plate (114) or on them It can be located in close proximity. The space remaining within the envelope between the inner surfaces of the first and eighth wings. The wings define the seven passages. The divider inside the left fixed inlet router (126) and the right fixed return and ascent router (128) The tips continue along the same axes as the lower cartridge wings (52) or along axes that are equivalent in terms of flow. Thus, instead of dispersing and redistributing itself into one large void, the air enters each passage in a controlled manner. and upon exiting, it reaches the right-turn zone with the same transition pattern. There is no sudden additional expansion or... during the underpasses. The aim is to avoid creating a contraction. In an example geometry, the heat transfer plate (114) under the glass chamber is approximately 250 x 220 mm in the outer shell, glass chamber The base can have a contact area of ​​approximately 244 x 214 mm. The net height of the wings (52) is approximately 41 mm. and its thickness may be approximately 2 mm. These values ​​are only examples and do not limit the scope of protection of the invention. The number of blades, their thickness, height, channel width, and plate dimensions can be changed according to the device capacity. The bottom barrier plate (124) forms the closed base of the air passages, preventing air from escaping under the cartridge. It reduces and limits downward heat loss. The plate (124) is made of a material with low thermal conductivity, It can be manufactured from a layered structure or suitably insulated metal. Independent bottom cleaning of the cartridge. and the heat cartridge drawer (90) can be removed or detached separately for cleaning and It provides ease of maintenance. 6 Right Turn, Distribution, and Exhaust Selection. The air coming out of the lower cartridge is turned from horizontal to vertical by the right fixed turn and rise guide (128). The router (128) arranges the exit pattern of the underpasses as seamlessly as possible to the right ascending channel. It carries the right riser duct, the upper inverted U-shaped distribution arm, the selector housing, and the hot air exhaust outlet together. The right riser forms the inverted U distribution and the hot air exhaust manifold (62). The manifold (62) of the device It extends across a significant portion of the usable front-to-rear depth and is leakproof in the upper cooking section. It can direct hot air longitudinally to the cooking area above the grill lid (31). At the top junction of the manifold (62), the cooking area above the airtight grille-cover (31) is connected to the top Selective or variable ratio to return and redirect manifold (61) and / or hot air exhaust path It has a flow-selective mechanism that directs the flow. The flow-selective mechanism controls a single multipath flow. It can be formed from a single control element or from multiple flow control elements working together. Preference In the two-element application, the mechanism consists of the lower main steering flap (106) and the upper exhaust / selector. It includes the flap (120). These elements are mechanical, electromechanical or motorized around fixed pivots. It can be moved as follows. In the preferred two-element application, hot air is delivered via a short and direct path at location Figure 3B. The lower guiding flap is directed to the upper surface of the leakproof grille-cover (31). Figure 3C position (106) directing the main airflow to the top return and diverter manifold by closing the direct grille feed arm. (61) gives; the upper selector flap (120) keeps the main hot air exhaust passage closed and only the area under the flap It allows a limited hot air exhaust flow through a fixed safety opening. Bottom flap in position as shown in Figure 3D. (106) direct grid feed arm, upper flap (120) upper return and steering manifold (61) It closes the outgoing air passage, and all of the rising air is expelled from the device through the hot air exhaust path. In position Figure 3E, the lower flap (106) holds the grid feed arm directly closed while the upper flap (120), The amount of air that will pass into the upper return and steering manifold (61) with angular intermediate positions is gradually It regulates the air flow, and the remaining hot air is directed to the exhaust path. In a single-element application, these functions are very common. The selector switch can be provided by a drum, rotor, disc, slide, or equivalent selector element. Steam Valve and Kinematic Coupling The glass reservoir (42) has a nipple or outlet neck that carries the vapor to the controlled humidity and steam valve assembly (70). It includes. The fixed inlet bearing of the controlled humidity and vapor valve assembly (70) closes this nipple when the drawer is closed. It meets. The movable nipple is slightly off the axis of the stationary bearing for most of the approach. It moves downwards. In the final part of the drawer closing, the kinematic path (185) is upwards with the nipple. By guiding it, it positions the stationary bearing on the central axis. This movement avoids direct impact with the seal surface. It enables connection by sliding and centering. In a preferred application, the vertical rise is approximately 1 mm. However, the amount of rise varies; The kinematic properties may vary depending on the seal stiffness, nipple diameter, drawer tolerances, and locking mechanism. guide rails, drawer slides, inclined guides, cam surfaces, groove taper, or a combination thereof. can be provided. 35 7 Main body of the controlled humidity and steam valve assembly (70), steam inlet line (176), steam discharge exhaust (71) and flow connection to the steam injection channel (72).
