Abstract
Description
Technical Field:The invention relates to the field of kitchen appliances, in particular hot air deep-fried nuts (1) and a removable drawer (2) which can be pushed in it and forms a cooking chamber (6). It further relates to a device, in particular based on a unit made of a carrier plate (11) in conjunction with an additional heater (10) for receiving a pizza brick or a grill plate, for inserting it into a cooking chamber (6) of such a drawer (2), for improving the preparation of flat bakery products, for example, such as pizzas, which require a high and precisely controlled under heat, preferably using a pizza brick (7) which is heated by an additional heater (10) and the temperature of which is detected by means of a temperature sensor (19).Background / Prior Art:Hot air deep-fried foods (1) usually cook food by means of an overhead heater (16) and a cooking chamber fan (15) which distributes a flow of hot air in the cooking chamber (8) of the drawer (2). The housing (1) often has ventilation openings (3) and a fresh air supply (17). The operation is often carried out via an operating panel ( 4). The drawer (2) typically has a handle (5) and often contains a cooking chamber (6) for receiving the item to be cooked.This functional principle is suitable for many foods, but often leads to uneven cooking in flat bakery products with a coating, such as pizza. In particular, the pizza base is not sufficiently heated and often remains doughy or raw, while the topping and rim are already strongly browned or overgart. The insertion of a pizza brick (7) into the container (6) of a conventional hot air deep deep deep deep-bred house (1) generally does not lead to the desired result of a crisp floor, due to the heat transfer that takes place primarily from above and the lack of sufficient under-heat.More advanced equipment such as the Typhur Dome Air Dryer or the TEFAL FW402H Easy Fry XL Surface Hot Air Deep House 2200 partially has a dedicated lower heater in addition to the top heat to achieve more uniform cooking. However, the heat transfer to an inserted pizza stone often takes place only indirectly, if at all, a pizza stone can be picked up, and a direct regulation of the stone temperature is thus not provided, which can lead to a significant temperature drop during the application of the cold dough, which cannot be compensated for quickly enough.Furthermore, German utility model DE 20 2025 000 179 discloses a solution for improving the pizza preparation in a hot air deep deep-air oven. This document describes a hot air deep-frying house of oven construction with a door (Bez. 2 in DE'179) and a cooking chamber (16 in DE'179), into which a removable unit (3 in DE'179) can be inserted. This unit comprises a pizza brick (12 in DE'179) and a pizza brick heater (13 in DE'179) that actively heats it. The unit is supplied with current via an automatic connection (20 in DE'179) in the rear cooking chamber region. For temperature control, a temperature sensor (18 in DE'179) is provided, which is arranged in the cooking chamber (16 in DE'179) in such a way that it is influenced by the pizza brick heater (13 in DE'179).Although this utility model discloses the basic principle of a removable, actively heated pizza brick unit, it differs from the object of the present invention: it relates explicitly to a hot air deep deep-fried fan with a door, while the present invention aims at the widely used hot air deep-fried fan with a removable drawer (2), which makes other constructional requirements. Moreover, the invention describes a more indirect temperature detection by means of a sensor (18 in DE'179) in the cooking chamber, while the present invention seeks a more precise control by directly detecting the temperature of the pizza brick (7) itself.Thus, there is still a need for a solution which, especially for hot air deep-fried nuts of the conventional type with drawer ( 2), offers an effective possibility, which is optimized in particular by direct measurement and regulation of the stone temperature, of preparing pizza with a particularly crisp floor. The invention further provides that the pizza stone (7) can be exchanged by a grill plate (27).Object of the invention:The invention is therefore based on the object of significantly improving the preparation of pizza in hot air deep deep-fried peas (1) of the type with a removable drawer (2). The aim is to create a device which, easily insertable and removable into the cooking chamber (6) of the drawer (2), enables a quick, intensive and above all precisely directly controlled heating of a pizza brick (7). In particular, the actual temperature of the pizza stone (7) is to be directly detected and kept at a constantly high level by active regulation of the heating power even under load by placing cold dough, in order to achieve a reproducibly crisp pizza base.Summary of the Invention:This object is achieved by a device having the features of claim 1 and by a method having the features of the dependent claims.The device according to the invention for inserting into the drawer (2) of a hot air deep deep-deep-deep-fat fuse (1) is preferably based on a carrier plate (11) and comprises a pizza brick (7) or optionally a grill plate (27) an additional heater (10) a connector plug (14) with contacts (20) for power supply and earthing via the connector socket (18) located on the rear wall of the shaft (8) of the hot air deep-fat fuse with an opening (12) for passing the temperature sensor (19) into the thermal influence range of the pizza brick (7) and optionally a temperature limiter (22) as an alternative to an adjustable temperature regulator. The carrier plate (11) preferably rests on the supports (9) in order to be positioned. The device is characterized in that it has an additional heating (10) for directly heating the pizza brick (7), at least one temperature sensor (19) for directly detecting the temperature of the pizza brick (7).List of reference numbers:1 Hot air deep-air deep-cooking 2 drawer 3 ventilation opening 4 operating panel 5 handle 6 cooking chamber 7 pizza stone 8 shaft 9 support 10 additional heating 11 carrier plate 12 temperature sensor opening 13 connection opening 14 connection plug 15 cooking chamber fan 16 surface heating 17 fresh air supply 18 connection socket 19 temperature sensor 20 contacts 21 temperature sensor lead-through 22 temperature limiter 23 air gap 24 fresh air channel 25 housing fan 26 motor 27 grill plate 28 reduced cooking chamberFigures:FIG. 1 : Entire device, front view, closed FIG. 2 : Complete apparatus, side view, closed FIG. 3 : Entire device, view obliquely from above, closed FIG. 4 : Entire device, view obliquely from above, opened FIG. 5 : Entire apparatus, view obliquely from above, opened, pizza stone raised FIG. 6 : Complete apparatus, view obliquely from above, opened, pizza stone and additional heating taken FIG. 7 : Hot air deep deep deep-fat deep-fat view FIG. 8 : Drawer, view from behind, obliquely above FIG. 9 : Drawer, view from the rear, obliquely above, pizza stone, heating and carrier plate removed.
