Description

Air fryer, air frying and baking equipment, cooking equipment and cleaning method thereof Technical Field

[0001] The present invention relates to the field of food cooking appliances, and in particular to an air fryer, an air frying and baking device, a cooking device and a cleaning method thereof. Background Art

[0002] As people's quality of life improves, cooking devices such as air fryers are becoming increasingly popular and widely used. Air fryers primarily use air to replace the hot oil in the frying pan to cook the ingredients. During this process, the hot air blows away the moisture on the surface of the ingredients, making the ingredients achieve a similar effect to deep-frying, thus achieving "air frying."

[0003] Since the air fryer uses hot air to fry food, food stains are particularly prone to accumulate on the top during the cooking process. Due to the presence of the heating tube on the top, it is difficult for users to clean it, resulting in the gradual accumulation of food stains on the top. These stains are repeatedly heated and melted during the cooking process, and the melted products may be discharged to the outside or fall into the food, affecting the health and safety of the user. At the same time, the stubborn oil stains on the top also affect the user's cooking experience.

[0004] Currently, there is a problem that the inner cavity of the air fryer is difficult to clean.

[0050] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0051] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0052] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0053] Cooking equipment such as air fryers easily accumulates grease and food residue on the top, making long-term use unhygienic. Cooking equipment such as ovens can self-clean through high-temperature carbonization or steam. In some solutions, cooking equipment such as ovens can also clean the cavity walls through catalytic oxidation.

[0054] Generally, high-temperature carbonization requires temperatures of 400 to 500 degrees Celsius. Air fryers, especially air fryers, cannot handle these high temperatures. Air fryers, especially air fryers, are relatively compact, and when temperatures reach 400 to 500 degrees Celsius, heat dissipation becomes a significant challenge, potentially damaging the equipment. Furthermore, catalytic oxidation typically requires a special coating on the interior walls and requires temperatures of 230, 250, or even 260 degrees Celsius to effectively decompose oil stains. Similarly, air fryers, especially air fryers, cannot handle these high temperatures.

[0055] Since the general temperature of air fryers can only reach about 200 degrees and there is no steam system, the self-cleaning function cannot be realized, so existing air fryers do not have a self-cleaning function.

[0056] Referring to Figures 1 to 4 , a cooking device in some embodiments includes a cooking device body 10, a cooking assembly 50, and a controller 90. The cooking device body 10 has a cooking cavity 11. At least a portion of the inner wall of the cooking cavity 11 is coated with a cleaning coating 11a. The cleaning coating 11a is used to adsorb contaminants, such as oil or grease, generated during the cooking process and catalytically decompose the contaminants, for example, into water and carbon dioxide, as will be further described below. The cooking assembly 50 is used to cook food placed within the cooking cavity 11. The controller 90 is used to control the operation of the cooking assembly 50. In some embodiments, when the controller 90 controls the operation of the cooking assembly 50 according to a cleaning temperature, the cleaning coating 11a can catalytically decompose the contaminants, such as oil or grease, for cleaning.

[0057] The cooking device in some embodiments may be a device with an air frying function, such as an air frying device and other devices with an air frying function. The air frying device may include an air fryer and an air oven, etc.

[0058] In some embodiments, the cooking device can be an air frying device, and accordingly, the cooking device body 10 is an air frying device body 10, and the cooking component 50 is a heating and air supply component 50; in some embodiments, when the air frying device is an air fryer, accordingly, the air frying device body 10 is an air fryer body 10.

[0059] For example, the main body 10 of the air frying and baking device includes a cooking cavity 11. In some embodiments, the cooking cavity 11 is used to place the food to be cooked. It should be noted that the cooking cavity 11 can be used to place the food to be cooked directly or indirectly, such as by placing the food in a removable hanging basket 13. Figure 3 shows an example. The air frying and baking device can be an air fryer, an air oven, or the like.

[0060] In some embodiments, at least a portion of the inner wall of the cooking cavity 11 is coated with a cleaning coating 11 a.

[0061] In some embodiments, the cleaning coating 11a is used to adsorb pollutants such as oil stains generated during the cooking process, and can catalytically decompose the adsorbed pollutants such as oil stains, for example, into at least water and carbon dioxide.

[0062] In some embodiments, the cleaning coating 11a is used to absorb oil stains generated during the cooking process and can act as a catalyst to make the reaction rate of the cleaning reaction greater than a preset rate under conditions greater than a first temperature. The cleaning reaction includes decomposing the absorbed oil stains, for example, decomposing them into at least water and carbon dioxide.

[0063] In some embodiments, the heating and air supply assembly 50 is disposed below the inner cavity top wall of the cooking cavity 11 , and at least the inner cavity top wall of the cooking cavity 11 is coated with a cleaning coating 11 a .

[0064] In some embodiments, the thickness of the cleaning coating 11 a is 10 μm to 1000 μm.

[0065] In some embodiments, the cleaning coating 11a has a porous structure, so that it is easier to absorb oil or grease during the cooking process.

[0066] In some embodiments, the cleaning coating 11a comprises hard particles of chromium, tungsten, rhenium, cobalt and cerium, which are catalysts for fat oxidation and are composed of at least one of the metals of copper, vanadium, bismuth, molybdenum, manganese, iron, nickel, platinum group metals, tin and niobium, oxides of the metals, and compounds of two or more of the metals and oxides.

[0067] The heating and air supply assembly 50 is used to deliver hot air for cooking to the cooking cavity 11. The heating and air supply assembly 50 heats the air and blows the hot air (hot air) toward the food in the cooking cavity 11 to cook. In some embodiments, the heating and air supply assembly 50 includes a heating element 51 and an air supply element 53. The heating element 51 is used to generate heat to heat the air when powered on, and the air supply element 53 is used to blow the heated air toward the food in the cooking cavity 11. In some embodiments, the heating element 51 can be implemented by a plurality of heating tubes. In some embodiments, the air supply element 53 can be implemented by a fan. To achieve a better air frying effect, the heating and air supply assembly 50 can be arranged below the top wall of the inner cavity of the cooking cavity 11. Specifically, the air supply element 53 and the heating element 51 are sequentially arranged below the top wall of the inner cavity of the cooking cavity 11. In this way, the air supply element blows air downward, and the air is heated by the heating element 51 before reaching the food placed on the bottom wall of the inner cavity of the cooking cavity 11.

[0068] The controller 50 is used to control the operation of the heating and air supply assembly 50. In some embodiments, the controller 50 controls the operation of the heating and air supply assembly 50 according to parameters such as temperature and / or wind speed. The temperature can be the cooking temperature and cleaning temperature mentioned herein.

[0069] In some embodiments, please refer to Figure 5, the air frying device may include one or more sensors, such as a temperature sensor 11b set near the heating element 51 and / or a temperature sensor 11c set at a preset position in the cooking cavity 11, etc. These sensors will be further described below.

[0070] The temperature parameter can be characterized by one or more of the current, voltage or power of the heating element 51. The temperature parameter can also be characterized by the temperature of the heating element 51. The cooking temperature can also be characterized by the temperature inside the cooking cavity 11. For example, the temperature of the heating element 51 can be obtained by setting a temperature sensor 11b near the cleaning coating 11a. The controller 50 can adjust the driving current and / or driving voltage of the heating element 51 through the temperature feedback from the temperature sensor 11b, so that the temperature near the cleaning coating 11a is stabilized at the desired temperature. Similarly, the temperature inside the cooking cavity 11 can be obtained by setting a temperature sensor 11c at a preset position inside the cooking cavity 11. The controller 50 can adjust the driving current and / or driving voltage of the heating element 51 through the temperature feedback from the temperature sensor 11c, so that the temperature inside the cooking cavity 11 is stabilized at the desired temperature.

[0071] Therefore, the controller 50 controls the operation of the heating and air supply component 50 according to the temperature parameter, which means that the parameter representing the temperature reaches the expected value.

[0072] The cooking temperature can be represented by the temperature inside the cooking cavity 11. The controller 50 controls the heating and air supply component 50 to work according to the cooking temperature, which means that the temperature inside the cooking cavity 11 reaches the above-mentioned cooking temperature; taking the cooking temperature of 160 degrees as an example, the controller 50 controls the heating and air supply component 50 to work according to the cooking temperature of 160 degrees, which means that the temperature inside the cooking cavity 11 reaches the cooking temperature of 160 degrees; taking the cooking temperature of 200 degrees as an example, the controller 50 controls the heating and air supply component 50 to work according to the cooking temperature of 200 degrees, which means that the temperature inside the cooking cavity 11 reaches the cooking temperature of 200 degrees; taking the cooking temperature of 230 degrees as an example, the controller 50 controls the heating and air supply component 50 to work according to the cooking temperature of 230 degrees, which means that the temperature inside the cooking cavity 11 reaches the cooking temperature of 230 degrees.

[0073] The cleaning temperature can be represented by the temperature near the cleaning coating 11a. The controller 50 controls the operation of the heating and air supply assembly 50 according to the cleaning temperature, which means that the temperature near the cleaning coating 11a reaches the above-mentioned cleaning temperature.

[0074] The air frying and baking equipment in some embodiments, such as an air fryer, can achieve very high temperatures. For example, during the cooking process, the temperature in the cooking cavity 11 can reach above 200 degrees, for example, above 220 degrees, for example, above 230 degrees, for example, above 250 degrees, for example, above 260, for example, above 280 degrees.

[0075] In some embodiments, the air frying and baking equipment, such as an air fryer, achieves good heat insulation and heat dissipation effects by improving the structure, thereby being able to achieve very high temperatures.

[0076] Referring to Figure 6 , in some embodiments, the cooking device body 10 includes a housing 14 and a partition 20. The partition 20 is disposed within the housing 14 to form a cooking cavity 11. The cooking device body 10 also includes a heat dissipation duct 60, which includes an air flow channel 63 and a flow guide channel 64. The housing 14 and the partition 20 cooperate to form the air flow channel 63, and the flow guide channel 64 communicates with the air flow channel 63. The cooking device body 10 also includes a flow guide cover 70, which is connected to the partition 20 and cooperates to form the spiral-shaped flow guide channel 64. It can be understood that the volute shape is similar to the shape of a snail. This structure can increase the pressure of the gas sucked into the guide channel 64, increase the flow rate of the cold air in the guide channel 64, and quickly take away the heat; it can be understood that the cooking device in some embodiments can be an air frying device, and accordingly, the cooking device body 10 is an air frying device body 10, and the cooking component 50 is a heating and air supply component 50; in some embodiments, when the air frying device is an air fryer, accordingly, the air frying device body 10 is an air fryer body 10.

[0077] In some embodiments, the cooking device further includes a driving member 81 and a cold air fan 82. The driving member 81 is provided on at least one of the partition mechanism 15 and the air deflector 70. The cold air fan 82 is in transmission connection with the driving member 81, and at least one of the cold air fan 82 and the controller 90 is provided in the guide channel 64. The cold air fan 82 is provided in the guide channel 64, and the driving member 81 drives the cold air fan 82 to rotate, which can accelerate the air flow speed in the guide channel 64 and the heat dissipation duct 60, thereby achieving a better heat dissipation effect. In addition, when the cold air fan 82 is working, the cold air in the air flow channel 63 can also reduce the heat conduction or radiation from the cooking cavity 11 to the controller 90, and to a certain extent, can also reduce the temperature of the controller 90; it can be understood that the cooking device can be an air frying device, and the air frying device can be an air fryer.

[0078] In some embodiments, the partition mechanism 20 includes a carrier 21, a first thermal insulator 22, and a second thermal insulator 23. The second thermal insulator 23 is connected at both ends to the carrier 21 and the first thermal insulator 22, respectively. The carrier 21, the first thermal insulator 22, and the second thermal insulator 23 cooperate to form the cooking cavity 11, with the carrier 21 serving as the bottom wall of the cooking cavity 11. At least one of the first thermal insulator 22 and the second thermal insulator 23 is provided with an insulating layer. The provision of the first thermal insulator 22 and the second thermal insulator 23 can reduce heat conduction or radiation from within the cooking cavity 11 to the exterior of the partition mechanism 20, thereby preventing excessive temperature rise in components located outside the partition mechanism 20 (such as the controller 90 and the housing 14), extending the service life of these components, and preventing burns to the user due to excessively high temperatures in the housing 14. It can also reduce excessive heat loss within the cooking cavity 11, thereby improving energy efficiency. The provision of the thermal insulation layer can increase the structural thermal resistance of the partition mechanism 20, reducing the amount of heat transferred from the cooking cavity 11 to the outside of the partition mechanism 20, thereby reducing the excessive temperature rise of components outside the partition mechanism 20. This improves the service life of these components and the safety of the cooking device. It can be understood that the thermal insulation layer includes a first thermal insulation layer 223 and a second thermal insulation layer 233.

[0079] The following describes how to perform self-cleaning of the equipment.

[0080] In some embodiments, the controller 90 controls the operation of the heating and air supply assembly 50 according to the cooking temperature for cooking; during the cooking process, the cleaning coating 11a can absorb pollutants such as oil or oil stains generated during the cooking process; when the cooking temperature is low (meaning that the first temperature required for catalytic decomposition is not reached), the cleaning coating 11a will hardly catalytically decompose the adsorbed pollutants such as oil or oil stains, or in other words, when the cooking temperature is low, the efficiency of the cleaning coating 11a in catalytically decomposing the adsorbed pollutants such as oil or oil stains is very low.

[0081] In some embodiments, the controller 90 controls the heating and air supply assembly 50 to operate (eg, operate for a preset duration) according to the cleaning temperature to perform cleaning, thereby catalytically decomposing the adsorbed pollutants such as oil or grease.

[0082] In some embodiments, the cooking temperature is less than the first temperature.

[0083] In some embodiments, the cooking temperature is less than or equal to 260 degrees.

[0088] In some embodiments, the cleaning temperature is such that the cleaning coating 11 a catalytically decomposes pollutants such as oil or grease at a reaction rate greater than a predetermined rate.

[0089] In some embodiments, the cooking temperature is no greater than the cleaning temperature.

[0090] In some embodiments, the preset duration is at least greater than or equal to 1 hour; in some embodiments, the preset duration is 2 hours.

[0091] In some embodiments, the controller 90 controls the heating and air supply component 50 to work for a preset time according to the cleaning temperature for cleaning, including: controlling the heating and air supply component 50 to work continuously for the preset time; or controlling the heating and air supply component 50 to work intermittently for the preset time; for example, the controller 50 obtains the temperature inside the cooking cavity 11 through the temperature sensor 11c. When the temperature inside the cooking cavity 11 is greater than the maximum temperature threshold (for example, 290 degrees), the controller 50 controls the heating and air supply component 50 to stop working; otherwise, the heating and air supply component 50 is controlled to continue or resume working.

[0092] Referring to FIG. 7 , in some embodiments, the cooking device includes an operation panel 12 disposed on the cooking device body 10 for user operation. In some embodiments, the operation panel 12 may also include a display screen 15 for displaying information such as the remaining cooking time and temperature.

[0096] In some embodiments, in response to the user's operation of the start button 01, the controller 90 controls the heating and air supply assembly 50 to operate according to the cooking temperature to perform cooking.

[0097] In some embodiments, in response to the user's operation of the cleaning button 02, the controller 90 starts the self-cleaning mode: the heating air supply component 50 is controlled to operate according to the cleaning temperature (for example, for a preset working time) to perform cleaning, thereby catalytically decomposing the adsorbed pollutants such as oil or oil stains.

[0098] In some embodiments, when it is determined that the conditions for the self-cleaning mode are met, the controller 90 further generates a prompt message, such as sound and light prompts through the display screen 15, to remind the user that the self-cleaning function of the device needs to be activated.

[0099] In some embodiments, when it is determined that the conditions for the self-cleaning mode are met, the controller 90 automatically starts the self-cleaning mode, that is, the controller 90 controls the heating and air supply component 50 to operate according to the cleaning temperature (for example, for a preset working time) for cleaning, thereby catalytically decomposing the adsorbed pollutants such as oil or oil stains.

[0101] In some embodiments, the cooking device has a preliminary cleaning mode and a deep cleaning mode. In some embodiments, the cooking device may be an air frying device. In some embodiments, the air frying device may be an air fryer.

[0102] In some embodiments, in response to the user's operation of the start button 01, the controller 90 controls the heating and air supply assembly 50 to operate according to the cooking temperature to perform cooking; and, in response to the user's operation of the start button 01, the preliminary cleaning mode is automatically started: the cleaning coating 11a absorbs pollutants such as oil or grease generated during the cooking process, and acts as a catalyst to cause a cleaning reaction to occur to decompose pollutants such as oil or grease.

[0103] In some embodiments, in response to the user's operation of the cleaning button 02, the controller 90 starts the deep cleaning mode: the heating and air supply component 50 is controlled to work for a preset time according to the cleaning temperature for cleaning; in some embodiments, the cleaning temperature is not less than the first temperature, so that the cleaning coating acts as a catalyst to catalyze the cleaning reaction to decompose oil stains.

[0104] The instructions for cooking temperature and cleaning temperature, etc. can be found above and will not be repeated here.

[0105] In some embodiments, when it is determined that the conditions for the deep cleaning mode are met, the controller 90 also generates a prompt message, such as sound and light prompts through the display screen 15, to remind the user that the deep cleaning function of the device needs to be activated.

[0106] In some embodiments, when it is determined that the conditions for the deep cleaning mode are met, the controller 90 automatically starts the deep cleaning mode, that is, the controller 90 controls the heating and air supply component 50 to operate according to the cleaning temperature (for example, for a preset working time) to perform cleaning, thereby catalytically decomposing the adsorbed pollutants such as oil or oil stains.

[0107] In some embodiments, the conditions for the deep cleaning mode include at least one of the following: the number of cooking times reaches a preset number; the total cooking time reaches a preset total time; and a regular deep cleaning time node is reached.
