Description

[0001] Air grill multicooker

[0002] The invention relates to electric kitchen appliances for cooking food using thermal action.

[0003] Today, various devices for cooking food using heat are available, such as air fryers. They cook food by convection of hot air in a closed system (without exhaust). Most have only one heating element at the top and, with rare exceptions, an additional lower heater, which maintains the temperature around and inside the bowl, but cannot, on its own, provide sufficient heat to cook the food. These heaters are tubular and do not touch the bowl, but instead heat the surrounding air.

[0004] Accordingly, in this version, the device cannot be used for preparing, for example, soups, porridges, cereals, where the volume of products and liquid is too large, and the convection of hot air will not be able to heat the water to a boil and, accordingly, cook the product.

[0005] Also known from the prior art are various devices (multicookers), for example, from source RU 151325 U1, published 03 / 27 / 2015, a multicooker is known that includes basic elements such as a housing, one or more heating elements, one or more temperature sensors, a container for products, a control module for the device, characterized by the front loading of the container for products.

[0006] However, the prior art does not yet offer a device that combines both an air fryer and a front-loading multicooker. Until now, it has been impossible to combine the functions of an air fryer (circulating hot air in a confined space containing the food being cooked) with those of a multicooker, which requires exhausting excess air from the cooking space. Therefore, the aim of the claimed invention is to address the shortcomings of the prior art.

[0007] The technical result, which the claimed invention is aimed at achieving, is the combination of the functions of a multicooker and an air grill in one device, ensuring the accuracy of product preparation by controlling the temperature of the bowl and the absence of condensation, as well as ease of use and removal of the bowl from the cavity of the device.

[0008] The airfryer / multicooker comprises a housing with a control panel and a cavity with an inlet on the side of the housing, as well as a bowl. A lower heating element, shaped like the bowl's bottom, is located in the cavity's bottom, with a spring-loaded temperature sensor protruding upward from the surface of the heating element. Guides are provided on the side walls of the cavity, and an upper heating element and fan are located in the upper part of the cavity. The bowl rests on a drawer containing a front panel and runners corresponding to the cavity's guides. The airfryer / multicooker comprises a lid mounted on the bowl, which is concave toward the center of the bowl and houses a lid handle with an opening, no larger than the lid's concavity. The upper and lower heating elements are equivalent.

[0009] The lower heating element can be made in the form of an induction panel or in the form of a resistor heating element.

[0010] The side walls of the bowl have handles.

[0011] There is a handle on the front panel of the drawer.

[0012] A locking mechanism may be provided at the bottom of the cavity inlet.

[0013] The claimed invention is further explained in more detail by drawings, in which: Fig. 1 shows the claimed device in general form.

[0014] Fig. 2 shows the claimed device with the bowl extended.

[0015] Fig. 3 shows the bowl of the claimed device.

[0016] Fig. 4 shows the claimed device and the bowl separately.

[0017] The claimed invention combines two devices with different functionality, an air grill and a multicooker, in one device.

[0018] The declared air grill-multicooker contains a body (1), a pull-out drawer (2), a bowl (3) for placing the product being cooked and a lid (15).

[0019] The housing (1) has a cavity (4) on the side for accommodating a pull-out drawer (2) with a bowl (3) placed therein during cooking. A single control panel (5) is located on the housing surface, designed to control and adjust the cooking process in both the air grill and the multicooker. A heating element (6) is located in the bottom of the cavity (4), the dimensions of which repeat the shape of the bottom of the bowl (3). The heating element (6) can be made either as a tubular heating element cast into silumin, or as an induction heating element located under a glass panel. In the center of the heating element (6) there is an opening, in which a temperature sensor (7) on a spring mechanism is located. The temperature sensor (7) is located slightly above the plane of the heating element (6).When the bowl (3) is installed on top of the heating element (6), the spring of the temperature sensor (7) is compressed, and the temperature sensor (7) is recessed inside the opening in the heating element (6), due to which good contact between the temperature sensor (7) and the bottom of the bowl (3) is achieved. On the side walls (8) of the cavity (4) there are guides (9), which are designed in such a way that they provide the possibility of installing the bowl (3) when sliding it into the cavity together with the drawer (2) along the guides (9) until it makes complete contact with the heating element (6) and the temperature sensor (7) and when the bowl (3) is completely pushed in. In the lower part of the inlet opening of the cavity (4) there may be a locking mechanism (10) ensuring the fixed fixation of the drawer (2) in the cavity (4) of the housing (1) in the fixed required position. In the upper part of the cavity (4) there is a second heating element and a fan to ensure that the claimed device performs the air grill function.The lower heating element (6), installed in the bottom of the cavity (4), and the second heating element, located in the upper part of the cavity (4) are full-fledged heating elements and can have a power of 800-2000 W, depending on the size of the device.

[0020] The drawer (2) comprises a front panel (12) continuing the shape of the housing (1) of the claimed device in the retracted state, and runners (13) designed for movement in the cavity (4) for the proper placement of the bowl (3) in the cavity (4) of the housing (1). For ease of removal of the drawer (2) from the cavity (4), a handle (14) is provided on the front panel (12).

[0021] The bowl (3) has side walls (16) and a bottom (17). Handles (18) are provided on the side walls (16) to facilitate removal of the bowl (3) from the drawer (2).

[0022] The lid (15) is designed to completely cover the interior of the bowl (3) and is concave toward the bottom (17) of the bowl (3). A handle (19) of the lid (15) is located in the center of the concave portion of the lid (15), and the handle (19) has a height that does not exceed the height of the lid (15). The concave design of the lid (15) ensures that condensate flows toward the center of the lid (15) and, accordingly, back into the bowl (3). An opening (20) is also made in the lid (15) to prevent the formation of steam pressure.

[0023] Thus, the claimed design of this device for cooking food using thermal action allows the bowl to be placed directly on the heating element, ensuring full contact between the bowl bottom and the heating element. The temperature sensor also makes direct contact with the bowl bottom for maximum temperature control. Furthermore, the presence of two fully functional heating elements, located at the top and bottom of the bowl, ensures minimal heating time for the food being cooked. Because the lower temperature sensor reads the temperature directly from the bowl, rather than from circulating hot air as in a conventional air fryer, the food is cooked with maximum precision, preventing burning or undercooking.Guides in the body cavity and runners on the drawer ensure proper placement of the bowl on the heating element, ensuring a tight fit with the temperature sensor. The lid's design prevents condensation from accumulating on the lid during cooking, and excess pressure is released through a hole in the lid. The combination of the lid, the lower heating element with a temperature sensor, and the fan-assisted ventilation algorithm allows this appliance to cook dishes that are impossible to prepare in a conventional air fryer, such as porridges, soups, stews, and any dishes with a high water content.

[0024] The single control panel features several automatic programs. Some are configured for air fryer mode, while others are configured for multicooker mode. In air fryer mode, the upper heating element functions as the primary heating element, while the lower one is used only to warm and maintain the cooking temperature in the bowl. In multicooker mode, on the other hand, the lower heating element functions as the primary heating element, cooking the food, while the upper heating element periodically turns on to remove condensation from the interior of the appliance and create a heating effect from all sides, similar to an oven. For example, the "Milk Porridge" program will function as a multicooker, while "Chicken Wings" will function as an air fryer. The number of programs on the panel may vary depending on the size of the appliance.It's also possible to independently select the heating element, activate them individually or simultaneously, and set the operating temperature and cooking time. This gives the user the freedom to choose their cooking method and isn't tied to a limited selection of automatic programs.

[0025] The claimed invention is new because the sum of its essential features is not known from the prior art and, accordingly, meets the patentability requirement of "novelty." The claimed invention meets the patentability requirement of "inventive step" because it is not readily apparent to a person skilled in the art.

[0026] The claimed invention meets the patentability requirement of “industrial applicability” since it can be used in industry.

[0027] Although the present invention has been disclosed with reference to preferred embodiments thereof, this is not intended to limit the present invention, and those skilled in the art of the present invention can modify and implement it without departing from the spirit and scope of the invention, therefore, the scope of protection of the present invention should be governed by the scope specified in the claims.
