Description

Air fryer with crisp and tender taste and adjustable

Technical Field

The invention relates to the technical field of kitchen appliances, in particular to an air fryer with crisp, tender and adjustable taste.

Background

An air fryer is a kitchen appliance for baking food by using hot air generated by a hot air component, and is popular with consumers in recent years due to the characteristic of low fat. When the air fryer is used for baking meat food materials, the moisture loss of the food materials is serious due to long-time blowing of hot air, the taste of the food materials can become dry firewood, and the requirements of users are difficult to meet.

In order to solve the problem of dry mouthfeel firewood when the air fryer toasts food materials, the patent CN201920621756.6 of the applicant discloses an air fryer with a steam generator, which can realize three cooking modes of pure steaming, pure toasting and steaming and toasting by controlling the opening and closing of the steam generator and a hot air assembly, and in the steaming and toasting mode, the humidity of a cooking cavity is improved due to the fact that the steam generator transmits steam to the cooking cavity, the moisture evaporation of the food materials is slowed down, the water content of the food materials is improved, the food materials become tender and juicy, and the mouthfeel is improved. However, the air fryer with the structure needs to be additionally provided with a steam generator, scale is easy to generate in the using process of the steam generator, the water scale is difficult to clean, steam in the pot body is easy to aggregate on the surface of food, and the surface of the food is not brittle.

Chinese patent CN201821252386.5 discloses an air fryer, and its pot body passes through exhaust inhibition structure intercommunication with external atmosphere, and the internal steam of inhibition pot is discharged outward, utilizes the steam that produces when the food heating to promote the humidity in the cooking chamber, and then reduces the moisture loss of food, because the steam in the cooking chamber is produced by food self evaporation, need not to set up steam generator in addition, simple structure, and the cooking chamber is in the boiling point that can promote water of pressurization, further slows down the evaporation of moisture. However, the air fryer with the structure can not be switched between normal pressure and pressurization due to the exhaust inhibition structure, the cooking cavity is always in a high-humidity environment, and the food material has only one taste, so that the requirements of users are difficult to meet.

The patent CN202123325677.7 of the applicant discloses an air fryer, a pressurizing valve capable of being switched between normal pressure and pressurizing is arranged on a machine head of the air fryer, when an exhaust port is plugged by the pressurizing valve, gas exhaust in a cooking cavity is inhibited, water vapor in the cooking cavity cannot be smoothly exhausted, humidity in the cooking cavity is increased, water loss of food materials is reduced, taste of the food materials is wet and tender, when the exhaust port is opened by the pressurizing valve, the water vapor in the cooking cavity can be smoothly exhausted, pressure in the cooking cavity is reduced, the humidity is reduced, the water loss of the food materials is increased, the taste of the food materials is dry and crisp, and then two tastes of dry and crisp and wet and tender can be realized.

However, if the same baking process is adopted when the air fryer is baked under the normal pressure and the micro-pressure conditions, that is, the baking time and the baking temperature are the same, the baking effect of the food material under the pressurized condition is poor and the upper surface of the food material is not colored enough compared with the baking under the normal pressure condition. The applicant has made extensive studies to find the root cause of the above problems, and found that the coloring of the upper surface of the food material is mainly affected by the heat radiation of the heating device. Currently, all commercial air fryers adopt a temperature sensor to detect the temperature near the heating device to control the opening and closing of the heating device, when the heating device detects that the temperature of the cooking cavity reaches the set shutdown temperature, the heating device is closed, when the temperature of the cooking cavity is smaller than the set shutdown temperature, the heating device is opened, namely, after the temperature in the cooking cavity reaches the target temperature, the heating device is intermittently opened to supplement the heat loss of the cooking cavity so as to maintain the temperature of the cooking cavity relatively constant. Under the micropressure environment, because the exhaust in the cooking cavity is restrained, the temperature loss of the cooking cavity is slowed down, the temperature of the cooking cavity is relatively constant, the starting frequency of the heating device is slowed down, the starting time is shortened, the radiation heat of the heating device to the upper surface of the food is insufficient, and finally, the upper surface of the food is colored inadequately.

Therefore, there is a need to address the problem of insufficient coloration of the upper surface of baked food materials in an air fryer under micro-pressure conditions.

Detailed Description

In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The air fryer is a cooking appliance for baking food materials by hot air, and when different food materials are baked, the air fryer can set different cooking temperatures so as to meet the cooking characteristics of the different food materials. At present, the air fryer on the market adopts the heating pipe to heat food more to set up the temperature controller that detects cooking cavity temperature near the heating pipe, after the user sets for the required target temperature of culinary art, the temperature controller is according to the shut-down temperature control heating pipe of heating pipe that corresponds with target temperature to cook the cavity and heat, when the temperature controller senses the shut-down temperature of temperature less than heating pipe, the heating pipe lasts the heating and promotes the culinary art intracavity temperature fast, when the temperature controller senses the temperature and reaches the shut-down temperature of heating pipe, temperature controller control heating pipe shut-down, the temperature controller resumes the heating when the temperature loss leads to the temperature to be less than the shut-down temperature of heating pipe and carries out the heat to supplement in order to maintain the temperature of culinary art chamber relatively invariable. It should be noted that the target temperature set by the air fryer is different from the shutdown temperature of the heating member, but the target temperature and the shutdown temperature are in one-to-one correspondence, and in general, when the air fryer is empty and is not loaded with food, the temperature controller controls the temperature of the central area of the cooking cavity to be the target temperature when the heating pipe is operated according to the shutdown temperature of the heating pipe corresponding to the target temperature.

The target temperature set by the air fryer is not necessarily set the same as the shut-down temperature of the heating tube. When the product is implemented, the corresponding relation is selected according to the distance between the temperature controller and the heating pipe, and in more actual products, the distance between the temperature controller and the heating pipe is closer, so that the shutdown temperature of the heating pipe is slightly higher than the target temperature, the overall actual temperature condition in the cooking cavity of the air fryer is better reflected, and if the distance between the temperature controller and the heating pipe is farther, the shutdown temperature of the heating pipe can be equal to the target temperature and even slightly lower than the target temperature. Thus, the target temperature set by the air fryer and the shut-off temperature of the heating pipe form a one-to-one relative magnitude relation, and the relation can be understood that when the target temperature set by the air fryer is increased, the shut-off temperature of the heating piece is correspondingly increased, and when the target temperature set by the air fryer is reduced, the shut-off temperature of the heating piece is correspondingly reduced.

Generally, for most actual products of the air fryer, when the air fryer works without food materials (no food materials exist in the air fryer), the temperature controller controls the closing temperature of the heating pipe according to the corresponding relation with the target temperature, and when the air fryer works to enter a steady state, the actual temperature of the central area of the cooking cavity is equal to or very close to the target temperature (for example, a deviation of 5-10 percent exists); when the air fryer is loaded with food materials, the temperature controller still controls the closing temperature of the heating pipe according to the corresponding relation with the target temperature, and the actual temperature of the central area of the cooking cavity can deviate from the target temperature. In other words, the one-to-one relative magnitude relationship between the target temperature set by the air fryer and the shut-down temperature of the heating element is not changed by the amount of food material in the cooking cavity of the air fryer.

In addition, the target temperature set in the air fryer may be set by the user himself in the actual product, for example, by operating a button and digitally displaying on a machine display device (for example, a display screen), or may be a mechanical knob, and set by the user selecting the knob; of course, for the air fryer with higher automation degree, the user does not need to manually set the target temperature, and only needs to select the corresponding starting button of the food material, so that the set target temperature of the air fryer is realized through a preset program, and at the moment, the target temperature can be digitally displayed on the display device or not displayed to the user, thereby further reflecting the automation of the machine.

Because different crowds have different taste demands, the air fryer capable of being switched between normal pressure and micro-pressure modes is invented in the prior art, the taste of the baked food materials under normal pressure is crisp, the taste of the baked food materials under micro-pressure is tender and juicy, and the taste demands of different crowds can be considered. However, the applicant has found that the coloring effect of the upper surface of the baked food material is far worse than the coloring effect of the lower surface of the food material by the same baking process under a slight pressure. In order to find the reason of the problem, the application further researches find that the insufficient coloring of the upper surface of the food material baked under the micro pressure mainly has two influencing factors, one factor is that the total cooking time of baking under the micro pressure is shortened to cause the irradiation time of the upper surface of the food material to be shortened, the other factor is that the heating pipe does not need to frequently open the heat loss of the supplementary cooking cavity due to the slow temperature loss of the cooking cavity when the food material is baked under the micro pressure, the opening frequency and the opening time of the heating pipe are reduced, and the irradiation quantity of the heating pipe is reduced to cause the uneven coloring of the upper surface of the food material.

In order to solve the problem that the upper surface of the baked food material of the air fryer is not sufficiently colored under the micro-pressure condition, the application provides the air fryer with crisp, tender and adjustable taste.

The air fryer of this application is provided with culinary art chamber and hot-blast subassembly, and hot-blast subassembly includes heating device and fan, and the hot-blast blowing that hot-blast subassembly during operation produced is to the food material in the culinary art intracavity in order to toast the culinary art intracavity. Specifically, the heating device is arranged above the cooking cavity, a temperature controller is arranged near the heating device, the temperature controller controls the heating device to continuously heat when the temperature of the cooking cavity is lower than the shutdown temperature, and the heating is stopped when the temperature reaches the shutdown temperature.

The air fryer of this application still is provided with exhaust suppression device, and exhaust suppression device can restrict the cooking cavity and exhaust, promotes the air humidity in the cooking cavity. When the cooking cavity is directly communicated with the atmosphere, the cooking cavity is at normal pressure, so that the water loss of food materials is more, the taste of the food materials is relatively dry and crisp, and the crisp baking can be realized; when the cooking cavity is communicated with the atmosphere through the exhaust inhibition device, the cooking cavity is in a micro-pressure state, the humidity in the cooking cavity is increased, the water loss of food materials is slowed down, the taste of the food materials is tender and juicy, and the tender baking is realized. The air fryer can achieve two cooking effects of crisp baking and tender baking by controlling the exhaust state of the cooking cavity.

The air fryer of this application has first toast mode and second toast mode, and the culinary art chamber is in ordinary pressure with the atmosphere direct communication when first toast mode, and the culinary art chamber is in micropressure with the atmosphere through exhaust suppression device intercommunication when the second toasts the mode, also the culinary art chamber is in ordinary pressure when first toast mode promptly, and the culinary art chamber is in micropressure when the second toasts the mode. For the same food material, the shutdown temperature of the heating device in the second baking mode is greater than that in the first baking mode. For example, the chicken wings are baked using an air fryer, the heating means being turned off at 180 ℃ in the first baking mode and 220 ℃ in the second baking mode. Because the shutdown temperature of the heating device is higher in the second baking mode, the temperature of the cooking cavity is higher in the second baking mode, the temperature difference between the cooking cavity and the external environment is larger, the temperature loss is quicker, the starting frequency of the heating device is increased, the radiation intensity of the heating device to the upper surface of the food is improved, and the coloring effect of the upper surface of the food is improved.

It will be appreciated that the shut-down temperature of the heating device is directly related to the target temperature selected by the user, and when the target temperature is determined, the shut-down temperature of the heating device is also determined, and of course, when the user adjusts the target temperature, the shut-down temperature of the heating device is also adjusted.

It will be appreciated that for the same food material, the first and second toasting modes may each be set to only one shut-down temperature during a single cooking event, or may be set to a plurality of different shut-down temperatures during a single cooking event. For the same food material, the shutdown temperature of the second baking mode heating device is greater than that of the first baking mode heating device, so long as the maximum value of the shutdown temperature of the second baking mode heating device is greater than that of the first baking mode. For example, the heating means has three shut-off temperatures of 120 ℃, 150 ℃, 180 ℃ during one cooking process when the first baking mode is used for baking chicken wings, and has two different shut-off temperatures of 150 ℃, 250 ℃ during one cooking process when the second baking mode is used, so long as the maximum shut-off temperature 250 ℃ of the second baking mode heating means is satisfied to be greater than the maximum shut-off temperature 180 ℃ of the first baking mode heating means.

It is understood that the difference between the shut-down temperature of the second toasting mode heating device and the shut-down temperature of the first toasting mode heating device may be 10 deg.c, 20 deg.c, 30 deg.c, 40 deg.c, etc., and preferably the difference between the shut-down temperature of the second toasting mode heating device and the shut-down temperature of the first toasting mode heating device is greater than 20 deg.c.

It is understood that the exhaust gas suppressing device of the present application may be a mechanical valve or an electromagnetic valve, as long as the cooking cavity can be blocked to form a micro-pressure environment. The pressure of the cooking cavity in the second baking mode is preferably 0.05kpa to 1kpa.

As a preferred embodiment of the present application, the exhaust gas suppressing means has an intermittent exhaust process after the heating means is first turned off in the second baking mode. The intermittent exhaust of the exhaust inhibition device can discharge steam of the cooking cavity, so that the heat loss speed in the cooking cavity is accelerated, the opening frequency of the heating pipe is improved, and the coloring effect of the upper surface of the food material is improved. In addition, compared with continuous exhaust, intermittent exhaust can keep the humidity of the cooking cavity to the greatest extent, reduce the evaporation of water of the food materials and improve the taste of the food materials.

It is understood that the intermittent exhaust process of the exhaust suppressing device after the first shutdown of the heating device may be that the exhaust suppressing device starts intermittent exhaust immediately after the first shutdown of the heating device, or that the exhaust suppressing device starts intermittent exhaust after a period of time after the first shutdown of the heating device.

As a preferred embodiment of the present application, in the second baking mode, the exhaust suppressing means does not exhaust air before the heating means is turned off for the first time. The cooking cavity is still in the heating process before heating device first shut down, if exhaust suppression device begins to exhaust before heating device first shut down can discharge excessive heat and lead to the intensification slower, and whole cooking time becomes longer, influences the culinary art effect of edible material. The heating device is firstly shut down before the exhaust inhibition device is not exhausted, so that on one hand, the heat loss of a cooking cavity can be reduced, the temperature rising speed is improved, on the other hand, the humidity of the cooking cavity can be improved, the water evaporation of food materials is reduced, the taste of the food materials is improved, meanwhile, the gas density of the cooking cavity is increased, the wind pressure of a fan is increased, more heat can be blown to the bottom of a pot body, the temperature of the food materials is improved, and the cooking speed is accelerated.

As a preferred embodiment of the present application, in the second toasting mode, the heating means have a plurality of different shut-off temperatures during a cooking process, the maximum shut-off temperature of the plurality of different shut-off temperatures being greater than the shut-off temperature of the heating means in the first toasting mode for the same food item. The second baking mode sets a plurality of different shutdown temperatures in a cooking process, namely the second baking mode heating device is used for heating in a segmented mode, and the segmented heating can avoid the problem that the food is difficult to bake due to rapid embrittlement of the food skin. It will be appreciated that in this embodiment, the first toasting mode may have only one or more than one heating device shut-down temperature during a single cooking event.

As a preferred embodiment of the present application, the shut-down temperature of the heating means is adjustable, and the maximum adjustable value of the shut-down temperature of the second toasting mode heating means is greater than the maximum adjustable value of the shut-down temperature of the first toasting mode heating means. The maximum adjustable value of the shutdown temperature of the second baking mode heating device is larger than that of the first baking mode heating device, the humidity of the cooking cavity in the first baking mode is low, and if the same shutdown temperature of the heating device is adopted in the second baking mode, food materials are easy to overheat and generate scorch. For example, the maximum off-temperature adjustable value of the heating device in the first toasting mode is 200 ℃ and the maximum off-temperature adjustable value of the heating device in the second toasting mode is 250 ℃ no matter what food material is being cooked.

As a preferred embodiment of the present application, the air fryer has preset food material functions, each preset food material function has a preset heating device shutdown temperature, the preset heating device shutdown temperature is adjustable, the same food material function, and the maximum adjustable value of the preset heating device shutdown temperature in the second baking mode is greater than the maximum adjustable value of the preset heating device shutdown temperature in the first baking mode. Different food material functions are preset in the air fryer, for example, a chicken wing function, an egg tart function, a French fries function and the like are preset, and when the chicken wing function is selected by a user in a first baking mode, the shutdown temperature of a heating device corresponding to the chicken wing in the first baking mode is preset to be 180 ℃ in the machine, and the shutdown temperature of the heating device can be adjusted to be 190 ℃ according to personal preference by the user, but the maximum temperature can be adjusted to be 200 ℃ which is allowed to be adjusted by the chicken wing function in the first baking mode; when a user selects the chicken wing function in the second baking mode, the shutdown temperature of the heating device corresponding to the chicken wing in the second baking mode is preset to be 220 ℃ in the machine, and the user can adjust the shutdown temperature of the heating device to 240 ℃ according to personal preference, but can only adjust the shutdown temperature to the maximum value of 250 ℃ which is allowed to be adjusted by the chicken wing function in the second baking mode at most; also selected is a chicken wing function, the second toasting mode allowing a maximum shut down temperature of the regulated heating device of 250 ℃ greater than the first toasting mode allowing a maximum shut down temperature of the regulated heating device of 200 ℃.

When the switch 54 on the second channel 52 is closed, the steam generated in the cooking cavity 1 during the operation of the air fryer can only be discharged through the first channel 51, and the discharge of the steam is limited because the first channel 51 is provided with the exhaust inhibition device 53, so that a micro-pressure environment is generated in the cooking cavity 1, the humidity is improved, the water loss of food materials is reduced, and the taste of the food materials is tender and juicy. When the second channel 52 is opened, steam generated by the cooking cavity 1 during the operation of the air fryer is preferentially discharged from the second channel 52, the interior of the cooking cavity 1 is in a normal pressure environment which is normally communicated with the atmosphere, the water loss of food materials is quicker, and the taste of the food materials is crisp.
