[0072] In the prior art, cooking equipment such as air fryers use the same or similar cooking modes for pizza and other foods, and there is no separate cooking mode for cooking pizza. Since most foods are made by evenly mixing multiple ingredients, when cooking, the fan uses a high-speed blowing mode to cook, which can speed up the cooking speed and complete the cooking. However, pizza has a double-layer structure, and the upper layer of the pizza is made up of toppings composed of vegetables, fruits, meat and other ingredients, and is directly exposed to the upper layer of the pizza, and the lower layer of the pizza is the crust; when cooking pizza, if the fan uses a high-speed blowing mode, the high-speed airflow formed by the high-speed blowing will quickly take away the moisture of the toppings on the top of the pizza, allowing the toppings composed of vegetables, fruits, meat and other ingredients to quickly dry out or even burn, resulting in poor appearance of the pizza and being more unpalatable.

[0073] The existing air fryer only has a heating element at the upper end of the cooking cavity to cook the food. However, when cooking pizza and other foods with two layers of different ingredients, the single heating method of upper heating is used, which can easily cause the toppings to burn, or the pizza base is heated relatively low, the pizza base is soft and cannot be baked crispy, and the pizza appearance and taste are relatively poor.

[0074] Based on the above analysis, the present application improves the cooking device (air fryer) by separately setting a pizza cooking mode. In the pizza cooking mode, the fan speed is set relatively low, and the fan speed is lower than other modes, for example, the fan speed is less than or equal to 1000r / min, such as 500r / min, 550r / min, 600r / min, 650r / min, etc. By setting a smaller fan speed, the air flow on the upper surface of the pizza is relatively slow during the cooking process, and the toppings composed of vegetables, fruits, meat and other ingredients on the surface of the pizza will not be dried quickly. When the pizza is cooked, it can still retain a certain amount of moisture, making the pizza look better and taste better.

[0075] Furthermore, the cooking device is provided with two heating elements, one of which is arranged at the upper end of the cooking cavity, and the other is arranged at the lower end of the cooking cavity, and the two heating elements can heat the food from above and below the food respectively. When cooking pizza, the two heating elements can bake and heat the upper and lower layers of the pizza respectively, and in particular, the heating element at the bottom can make the pizza bottom crispy, so that the pizza bottom forms a three-dimensional support, and the pizza will not be soft, has a better appearance, and can also improve the taste.

[0076] Furthermore, the two heating elements in the cooking device can be controlled separately, so that during the cooking process, the two heating elements can output different amounts of heat respectively, and can achieve heating and cooking of double-layer food at different temperatures on the upper and lower sides, so that the pizza toppings and the pizza base can be heated and cooked at the same time. For example, when heating a pizza, the cooking heat generated by the heating element located above the pizza is less than or equal to the cooking heat generated by the heating element below the pizza, so that the pizza base is baked crispy while the toppings composed of vegetables, fruits, meat and other ingredients on the top of the pizza are not burned and retain a certain amount of moisture, so that a better cooking effect can be achieved.

[0077] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, 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 part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0078] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0079] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0080] In one embodiment, a cooking device is provided. The cooking device may be an air fryer or other device that cooks food by electric heat.

[0081] In this embodiment, the cooking device adds a new cooking mode, or adjusts an existing cooking mode. For the convenience of description, the newly added or modified cooking mode is named the first cooking mode, or the pizza cooking mode. The first cooking mode mainly cooks pizza. The first cooking mode is also suitable for cooking food with upper and lower layers of different ingredients similar to pizza. Among them, the fan speed of the first cooking mode is limited to a relatively low speed. The low-speed fan can still take into account the transfer of hot air to the top of the food surface to heat the food, and can also avoid the excessive wind speed from quickly drying the toppings composed of vegetables, fruits, meat and other ingredients on the upper surface of the pizza. The fan uses a low wind speed to ensure that the ingredients on the upper surface of the pizza remain hydrated after the pizza is made, and has a better taste and appearance.

[0082] The cooking device is also provided with a first heating element and a second heating element, which are respectively installed above and below the supporting element, and are used to heat the upper and lower ends of the food. Since pizza is a double-layer food with different ingredients, better cooking effects can be achieved by heating it with different upper and lower heating elements. For example, the second heating element located at the bottom can cook and heat the lower crust of the pizza until it is crispy, which helps to shape the pizza, so that the lower crust will not become soft and can support the ingredients on the upper layer in three dimensions. The first heating element and the second heating element can be controlled separately, and different cooking temperatures are generated at the pizza toppings and crust, so that the pizza toppings and crust can be cooked at the same time, so as to cook a pizza with better appearance and taste.

[0083] Please refer to Figure 1 and Figure 2 The cooking device in this embodiment mainly includes a shell 1, a carrier 2, a first heating element 3, a second heating element 4, a fan 5 and a controller 6.

[0084] The housing 1 has a cooking cavity 11 and an installation cavity 12. The cooking cavity 11 is located in the housing 1. The housing 1 may be a drawer-type structure, and the cooking cavity 11 may be opened and closed by pulling to put in and take out food. The housing 1 may also be a flip-type structure, and the cooking cavity 11 may be opened and closed by flipping to put in and take out food.

[0085] The installation cavity 12 and the cooking cavity 11 can be separated by a structure such as an inner cover. The cooking cavity 11 is used for cooking food, and the installation cavity 12 is used for accommodating and installing components. The installation cavity 12 and the cooking cavity 11 are separated by a space, which can prevent the heat in the cooking cavity 11 from diffusing into the installation cavity 12 and affecting the normal operation of the components in the installation cavity 12.

[0086] The carrier 2 is installed in the cooking cavity 11 and is located at the lower end of the cooking cavity 11. The carrier 2 can be fixed in the cooking cavity 11 by means of screws, clamping, etc. The carrier 2 can also be directly placed in the cooking cavity 11. The placed carrier 2 and the shell 1 form a separate structure. The user can place food on the carrier 2 and then put them into the cooking cavity 11 together, and take the food and the carrier 2 out of the cooking cavity 11 together. For example, the carrier 2 is installed in the cooking cavity 11 in a pulling manner. The carrier 2 is provided with a handle exposed to the shell 1. The user can push the carrier 2 into the cooking cavity 11 and pull the carrier 2 out of the cooking cavity 11 through the handle.

[0087] The carrier 2 may be a tray structure, and the carrier 2 may be a good conductor structure such as metal, so that during the heating process, the carrier 2 can transfer heat to the food, improve the cooking efficiency, and achieve more uniform heating and cooking of the bottom of the food.

[0088] The first heating element 3 and the second heating element 4 are resistance heating structures respectively. For example, the first heating element 3 and the second heating element 4 are copper tubes. The first heating element 3 and the second heating element 4 can convert electrical energy into thermal energy to heat the surrounding air, and the hot air cooks the food.

[0089] The first heating element 3 is installed in the cooking cavity 11 and is located at the upper end of the cooking cavity 11. The first heating element 3 is located above the carrier 2. There is enough space between the first heating element 3 and the carrier 2 to accommodate food. The first heating element 3 is used to heat the surrounding air to heat the upper end of the food.

[0090] The second heating element 4 is installed in the cooking cavity 11 and is located at the lower end of the cooking cavity 11. The second heating element 4 is located below the carrier 2. The second heating element 4 is used to heat the surrounding air so as to heat the lower end of the food. The second heating element 4 can also be in direct or indirect contact with the carrier 2. The second heating element 4 transfers heat to the carrier 2, and the carrier 2 then transfers heat to the food to heat the lower end of the food.

[0091] The first heating element 3 and the second heating element 4 can be a spiral tube structure, and the spiral tube forms a heating surface with a larger heating area, which is conducive to improving the uniformity and efficiency of heating and baking. Figure 8 .

[0092] The motor part of the fan 5 is installed in the installation cavity 12 to prevent the motor from being damaged by heat. The blade part of the fan 5 is installed in the cooking cavity 11, and the blade of the fan 5 is located above the carrier 2 and above the first heating element 3. The fan 5 can blow air from top to bottom in the cooking cavity 11, and the fan 5 can blow the hot air heated around the first heating element 3 to the upper surface of the food to heat the food.

[0093] The controller 6 is installed in the installation cavity 12. The controller 6 can be a circuit board or other structure. The controller 6 is electrically connected to the first heating element 3, the second heating element 4 and the fan 5. The controller 6 is used to control the heating power and heating time of the first heating element 3 and the second heating element 4, and is also used to control the speed and blowing time of the fan 5. Among them, the controller 6 can independently control the first heating element 3, the second heating element 4 and the fan 5 respectively, so that in any cooking mode, the first heating element 3 and the second heating element 4 have different heating temperatures, and can be combined to form different cooking modes to meet the heating and cooking requirements of different foods. In different cooking modes or preheating modes, the temperatures of the first heating element 3 and the second heating element 4 can also be different. It can be understood that in some embodiments, the cooking mode is different from the preheating mode, and the mode from the cooking device receiving the instruction to start cooking to the end of cooking is the cooking mode.

[0094] In other embodiments, the controller 6 may not be installed in the cooking device, and the controller 6 may also be a controller of a mobile terminal or other device, and a wireless communication module is provided in the cooking device, and the controller 6 is connected to the first heating element 3, the second heating element 4 and the fan 5 by signals through the wireless communication module. That is, the controller 6 may also control the cooking operation of the cooking device by remote wireless communication.

[0095] In this embodiment, the cooking device includes a first cooking mode and a non-first cooking mode. The cooking modes of the cooking device are all pre-set in the controller 6, and the controller 6 is used to control the cooking mode of the cooking device. Among them, the first cooking mode can also be called a pizza cooking mode. The first cooking mode is mainly used to cook pizza. The first cooking mode can also be used to cook other foods with double-layer ingredients similar to pizza. The non-first cooking mode may include one or more other cooking modes, and the non-first cooking mode is used to cook other foods besides pizza.

[0096] In this embodiment, in the first cooking mode, the controller 6 controls the speed of the fan 5 to be the first speed; in the non-first cooking mode, the controller 6 controls the speed of the fan 5 to be the non-first speed, and the first speed is not greater than the non-first speed. The first speed is not greater than the non-first speed, including at least the following situations: the first speed and the non-first speed can be fixed values, then the first speed is not greater than the non-first speed; the first speed and the non-first speed can also be interval range values, then the maximum value of the first speed is not greater than the maximum value of the non-first speed, the interval range value of the first speed and the interval range value of the non-first speed can not overlap, or partially overlap; the first speed and the non-first speed can also be interval range values, then the average value of the first speed in the cooking mode is not greater than the average value of the non-first speed in the non-first cooking mode.

[0097] In the first cooking mode, the speed range of the first speed of the fan 5 does not exceed 1000 r / min, and the maximum value of the first speed of the fan 5 is less than or equal to 1000 r / min. Preferably, the first speed of the fan 5 is about 500 r / min. In the non-first cooking mode, the speed range of the second speed of the fan 5 exceeds 1000 r / min, and the maximum value of the non-first speed of the fan 5 is greater than 1000 r / min, for example, the non-first speed of the fan 5 is about 1500 r / min.

[0098] In this embodiment, the first speed of the fan 5 in the first cooking mode is not greater than the non-first speed of the fan 5 in the non-first cooking mode, and the speed of the fan 5 in the first cooking mode is set to be slower. When the first cooking mode cooks pizza, the fan 5 with a slower speed will not allow the toppings composed of vegetables, fruit pulp and other ingredients on the surface of the pizza to dry out quickly, thereby maintaining a good taste of the ingredients; and the cooking equipment is provided with a first heating element 3 and a second heating element 4, which are respectively arranged above and below the carrier 2, the first heating element 3 located above can heat the upper ingredients of the pizza, and the second heating element 4 located below can heat the lower ingredients of the pizza, and the second heating element 4 can bake the pizza crust to be crispy, so that the pizza has a better appearance and taste.

[0099] In other embodiments, in the first cooking mode, the controller 6 also controls the heating value of the first heating element 3 to be not greater than the heating value of the second heating element 4, so as to further improve the cooking effect of the pizza.

[0100] The controller 6 can control the heating time and / or heating power of the first heating element 3 and the second heating element 4 separately and independently.

[0101] In the first cooking mode, the controller 6 can control the first heating time of the first heating element 3 to be not greater than the second heating time of the second heating element 4; or the controller 6 can control the first heating power of the first heating element 3 to be not greater than the second heating power of the second heating element 4; or the controller 6 can control the first heating time of the first heating element 3 to be not greater than the second heating time of the second heating element 4, and the controller 6 can control the first heating power of the first heating element 3 to be not greater than the second heating power of the second heating element 4. The controller 6 controls the heating time and / or heating power of the first heating element 3 and the second heating element 4 respectively, and can control the heating value of the first heating element 3 to be not greater than the heating value of the second heating element 4, so that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food, and finally the pizza toppings and pizza base requiring different cooking heats can be cooked at the same time.

[0102] Among them, the first heating power of the first heating element 3 is not greater than the second heating power of the second heating element 4 includes: the average heating power of the first heating element 3 is not greater than the average heating power of the second heating element 4; or, at any time point within a certain time interval, the heating power of the first heating element 3 is not greater than the heating power of the second heating element 4.

[0103] The heating value of the first heating element 3 is controlled not to be greater than the heating value of the second heating element 4, and the temperature of the first contact medium of the food close to the first heating element 4 is also controlled not to be greater than the temperature of the second contact medium of the food close to the second heating element 4. The first contact medium is air, and the air layer in contact with the upper surface of the food heats and cooks the food; the second contact medium is a support member 2 or a placement structure such as a tray for placing the food in the support member 2. By controlling the temperature of the first contact medium to be not greater than the temperature of the second contact medium, it can be more accurately achieved that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food.

[0104] In the first cooking mode, the cooking heat generated on the upper surface of the food is not greater than the cooking heat generated on the lower surface of the food. This makes the cooking heat on the upper surface of the pizza not greater than the cooking heat on the lower surface of the pizza. The lower surface of the pizza has a smaller cooking heat, which can ensure that the toppings composed of vegetables, fruits, meat and other ingredients are cooked and not dried out or crispy, and have a better taste; while the lower surface of the pizza has a larger cooking heat, which can make the pizza bottom layer cooked and crispy, not only forming a three-dimensional support, not soft, but also having a better taste.

[0105] In the non-first cooking mode, the first heating element 3 and the second heating element 4 can be controlled separately, or can be controlled to heat synchronously or sequentially, the calorific value of the first heating element 3 and the calorific value of the second heating element 4 can be the same, or the calorific value of the first heating element 3 is not greater than the calorific value of the second heating element 4, or the calorific value of the first heating element 3 is greater than the calorific value of the second heating element 4. That is, in the non-first cooking mode, the heating order and calorific value of the first heating element 3 and the second heating element 4 can be controlled according to the cooking requirements of other foods.

[0106] In a non-first cooking mode, the controller 6 may also control one of the first heating element 3 and the second heating element 4 to heat, while the other one does not heat, so as to meet the cooking requirements of specific food.

[0107] The cooking device is provided with a first heating element 3 and a second heating element 4 which can be controlled separately. The first heating element 3 and the second heating element 4 are respectively arranged above and below the carrier. The second heating element located below can bake the pizza crust to a crispy state, which has a better appearance and taste. In addition, the heat generated by the first heating element 3 is not greater than the heat generated by the second heating element 4, so that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food, and the cooking heat on the upper surface of the pizza is not greater than the cooking heat on the lower surface, so as to cook a pizza with a better appearance and taste.

[0108] In other embodiments, the non-first cooking mode includes a preheating mode. In the preheating mode, the controller 6 is used to control the rotation speed of the fan 5 to be a preheating rotation speed, which is greater than the first rotation speed in the first cooking mode.

[0109] The first cooking mode may include a preheating mode. In the preheating mode, the controller 6 controls the fan 5 to run at a high speed so that the cooking cavity 11 can be quickly and evenly heated to complete the preheating, and then the pizza is placed in the cooking cavity 11, and finally the pizza is cooked using the first cooking mode.

[0110] The first cooking mode may not include the preheating mode, and the first cooking mode may complete the cooking of the pizza alone.

[0111] The preheating mode can also be used as a preheating mode before one or more other non-first cooking modes. After the preheating mode is completed, other non-first cooking modes are performed to meet the needs of food cooking.

[0112] The preheating mode setting allows food to start cooking in a higher temperature environment, which can speed up the cooking efficiency of food and improve the taste of some food.

[0113] In other embodiments, in the heating mode, the fan 5 can also be preheated at a low speed to meet the cooking requirements of some foods.

[0114] In other embodiments, the non-first cooking mode includes one or more second cooking modes, wherein the plurality of second cooking modes are a plurality of other modes different from the first cooking mode, that is, the plurality of second cooking modes are a plurality of different cooking modes. The first cooking mode and the second cooking mode are used to cook at least one different food, for example, the first cooking mode is used to cook pizza, and the second cooking mode is used to cook other food besides pizza.

[0115] In the second cooking mode, the controller 6 is used to control the speed of the fan 5 to be a second speed, and the second speed is greater than the first speed in the first cooking mode. Among them, multiple second cooking modes have different second speeds, and multiple second speeds are all greater than the first speed.

[0116] For example, a second cooking mode is mainly used for cooking ordinary bread. Ordinary bread is mainly made of flour. In the second cooking mode, the fan 5 uses a second speed with a higher speed to blow the high-temperature air around the first heating element 3 to the top and around the bread, which can achieve faster and more efficient cooking and save cooking time.

[0117] Please refer to Figure 3 and Figure 4 In other embodiments, the cooking device further includes a first temperature sensor 7 and a second temperature sensor 8. The first temperature sensor 7 is installed in the cooking cavity 11 and is located above the carrier 2. The first temperature sensor 7 can be installed at the top of the cooking cavity 11 or a position close to the top. The second temperature sensor 8 is installed in the cooking cavity 11 and is located below the carrier 2. The second temperature sensor 8 can be installed at the bottom of the cooking cavity 11 or a position close to the bottom. The first temperature sensor 7 and the second temperature sensor 8 are located above and below the food, respectively. The first temperature sensor 7 is used to detect the temperature above the food and generate a first detection signal; the second temperature sensor 8 is used to detect the temperature below the food and generate a second detection signal.

[0118] The controller 6 is connected to the first temperature sensor 7 and the second temperature sensor 8 by signals respectively. The controller 6 is used to control the heating power and / or heating time of the first heating element 3 and the second heating element 4 according to the first detection signal and the second detection signal. The first temperature sensor 7 and the second temperature sensor 8 are used as real-time temperature feedback components. The controller 6 can obtain the temperature above and below the cooking cavity 11 in real time through the first temperature sensor 7 and the second temperature sensor 8 to achieve more accurate temperature control and improve the cooking effect.

[0119] For example, in the first cooking mode of cooking pizza, the controller 6 is used to control the temperature range under the food to be 200-210°C; when the second temperature sensor 8 is used to detect that the temperature range under the food is 200-210°C, the temperature is determined to be normal; when the second temperature sensor 8 is used to detect that the temperature under the food is not greater than 200°C, or is greater than 210°C, that is, when the temperature under the food is not within the range of 200-210°C, the temperature is determined to be abnormal, and the controller 6 controls the second heating element 4 to reduce or increase the heating power accordingly to restore the temperature under the food to within 200-210°C.

[0120] In other embodiments, the first temperature sensor 7 and the second temperature sensor 8 may be provided in plurality, and the detection signals of the plurality of first temperature sensors 7 and the second temperature sensors 8 may be averaged to obtain a more accurate real-time temperature value. In addition, the provision of multiple sensors may eliminate detection errors or detection errors caused by abnormality of individual sensors, and may improve the accuracy of real-time temperature detection.

[0121] Please refer to Figure 5 In other embodiments, the cooking device is further provided with a first cooking mode button 9. The first cooking mode button 9 can be directly set on the outer side of the shell 1. The first cooking mode button 9 is a physical button. The first cooking mode button 9 is electrically connected to the controller 6. The first cooking mode button 9 is used to generate a first control signal. The controller 6 enters the first cooking mode according to the first control signal.

[0122] When the cooking device is in use, the user can directly enter the first cooking mode through the first cooking mode button 9 without going through multiple menu selections. The one-button operation is simple and efficient.

[0123] In other embodiments, when a touch screen is provided on the outer side of the cooking device, a virtual button for the first cooking mode is provided on the main menu of the touch screen, and the first cooking mode can be entered by one click through the virtual button, which is simple and efficient.

[0124] In other embodiments, the cooking device is further provided with physical buttons or virtual buttons for other cooking modes to efficiently and quickly enter other cooking modes. For example, a second cooking mode button is provided on the outside of the cooking device, and the second cooking mode button is connected to the controller 6 by signal. The second cooking mode button is used to generate a second control signal, and the controller 6 can enter the second cooking mode according to the second control signal.

[0125] In one embodiment, a cooking method is provided, and the cooking method uses the cooking device in the above embodiment to achieve cooking.

[0126] Please refer to Figure 6 The cooking method is executed by the controller 6 of the cooking device, and the cooking method mainly includes the following steps:

[0127] S11: Select a cooking mode according to the control signal;

[0128] A control signal is acquired, and the cooking device is controlled to enter a first cooking mode or a non-first cooking mode according to the control signal.

[0129] The user can select the first cooking mode or the non-first cooking mode through the buttons or interface menu of the cooking device. When the user selects the first cooking mode, a first control signal is generated, and the controller 6 obtains the first control signal and controls the cooking device to enter the first cooking mode to cook food; when the user selects the non-first cooking mode, a non-first control signal is generated, and the controller 6 obtains the non-first control signal and controls the cooking device to enter the non-first cooking mode; for example, when the user selects the second cooking mode, a second control signal is generated, and the controller 6 obtains the second control signal and controls the cooking device to enter the second cooking mode.

[0130] When the cooking device is provided with a first cooking mode button 9, after the user presses the first cooking mode button 9, the first cooking mode button 9 generates a first control signal, the controller 6 obtains the first control signal, and controls the cooking device to enter the first cooking mode to cook food. Entering the first cooking mode by operating the first cooking mode button 9 is simple and efficient, and has a better user experience.

[0131] S12: Entering a cooking mode, the first rotation speed of the fan 5 in the first cooking mode is not greater than the non-first rotation speed of the fan 5 in the non-first cooking mode.

[0132] The controller 6 controls the cooking device to enter different cooking modes according to different control signals obtained.

[0133] In the first cooking mode, the controller 6 controls the first heating element 3 and the second heating element 4 to heat, and controls the fan 5 to transfer the heat generated by the first heating element 3 to the cooking cavity 11. The fan 5 can also drive the heat generated by the second heating element 4 to transfer to the cooking cavity 11 to cook food. The fan 5 drives the air in the cooking cavity 11 to flow, so as to drive the heat generated by the first heating element 3 and the second heating element 4 to flow in the cooking cavity 11 to cook food.

[0134] In the non-first cooking mode, the controller 6 controls one or both of the first heating element 3 and the second heating element 4 to heat, and controls the fan 5 to transfer the heat generated by one or both of the first heating element 3 and the second heating element 4 to the cooking cavity 11 to cook food.

[0135] In the first cooking mode, the controller 6 controls the speed of the fan 5 to be the first speed; in the non-first cooking mode, the controller 6 controls the speed of the fan 5 to be the non-first speed, and the first speed is not greater than the non-first speed. The first speed is not greater than the non-first speed including at least the following situations: the first speed and the non-first speed can be fixed values, then the first speed is not greater than the non-first speed; the first speed and the non-first speed can also be interval range values, then the maximum value of the first speed is not greater than the maximum value of the non-first speed, and the interval range value of the first speed and the interval range value of the non-first speed may not overlap, or partially overlap.

[0136] In the first cooking mode, the speed range of the first speed of the fan 5 does not exceed 1000 r / min, and the maximum value of the first speed of the fan 5 is less than or equal to 1000 r / min. Preferably, the first speed of the fan 5 is about 500 r / min. In the non-first cooking mode, the speed range of the second speed of the fan 5 exceeds 1000 r / min, and the maximum value of the non-first speed of the fan 5 is greater than 1000 r / min, for example, the non-first speed of the fan 5 is about 1500 r / min.

[0137] In the cooking method of the present embodiment, in the first cooking mode, the first speed of the fan 5 is controlled not to be greater than the non-first speed of the fan 5 in the non-first cooking mode, and the speed of the fan 5 in the first cooking mode is set to be slower. When the pizza is cooked in the first cooking mode, the fan 5 with a slower speed will not allow the toppings composed of vegetables, fruit pulp and other ingredients on the surface of the pizza to dry out quickly, thereby maintaining the good taste of the ingredients.

[0138] In other embodiments, in the first cooking mode, the controller 6 controls the heating value of the first heating element 3 to be no greater than the heating value of the second heating element 4 to improve the cooking effect of the pizza.

[0139] The controller 6 can control the heating time and / or heating power of the first heating element 3 and the second heating element 4 separately and independently.

[0140] In the first cooking mode, the controller 6 can control the first heating time of the first heating element 3 not to be greater than the second heating time of the second heating element 4; or the controller 6 can control the first heating power of the first heating element 3 not to be greater than the second heating power of the second heating element 4; or the controller 6 can control the first heating time of the first heating element 3 not to be greater than the second heating time of the second heating element 4, and the controller 6 can control the first heating power of the first heating element 3 not to be greater than the second heating power of the second heating element 4. The controller 6 controls the heating time and / or heating power of the first heating element 3 and the second heating element 4 respectively, and can control the heat generated by the first heating element 3 not to be greater than the heat generated by the second heating element 4, so that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food.

[0141] Among them, the first heating power of the first heating element 3 is not greater than the second heating power of the second heating element 4 includes: the average heating power of the first heating element 3 is not greater than the average heating power of the second heating element 4; or, at any time point within a certain time interval, the heating power of the first heating element 3 is not greater than the heating power of the second heating element 4.

[0142] The heating value of the first heating element 3 is controlled not to be greater than the heating value of the second heating element 4, and the temperature of the first contact medium of the food close to the first heating element 4 is also controlled not to be greater than the temperature of the second contact medium of the food close to the second heating element 4. The first contact medium is air, and the air layer in contact with the upper surface of the food heats and cooks the food; the second contact medium is a support member 2 or a placement structure such as a tray for placing the food in the support member 2. By controlling the temperature of the first contact medium to be not greater than the temperature of the second contact medium, it can be more accurately achieved that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food.

[0143] In the first cooking mode, the cooking heat generated on the upper surface of the food is not greater than the cooking heat generated on the lower surface of the food. This makes the cooking heat on the upper surface of the pizza not greater than the cooking heat on the lower surface of the pizza. The lower surface of the pizza has a smaller cooking heat, which can ensure that the toppings composed of vegetables, fruits, meat and other ingredients are cooked and not dried out or crispy, and have a better taste; while the lower surface of the pizza has a larger cooking heat, which can make the pizza bottom layer cooked and crispy, not only forming a three-dimensional support, not soft and mushy, but also having a better taste; and, when the upper and lower parts of the pizza are finished cooking, they can both be in a relatively good cooking state.

[0144] In the non-first cooking mode, the first heating element 3 and the second heating element 4 can be controlled separately, or can be controlled to heat synchronously or sequentially, the calorific value of the first heating element 3 and the calorific value of the second heating element 4 can be the same, or the calorific value of the first heating element 3 is not greater than the calorific value of the second heating element 4, or the calorific value of the first heating element 3 is greater than the calorific value of the second heating element 4. That is, in the non-first cooking mode, the heating order and calorific value of the first heating element 3 and the second heating element 4 can be controlled according to the cooking requirements of other foods.

[0145] In a non-first cooking mode, the controller 6 may also control one of the first heating element 3 and the second heating element 4 to heat, while the other one does not heat, so as to meet the cooking requirements of specific food.

[0146] In the present cooking method, the controller 6 can independently control the first heating element 3 and the second heating element 4, and control the heating value of the first heating element 3 not to be greater than the heating value of the second heating element 4, so that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food, and the cooking heat on the upper surface of the pizza is not greater than the cooking heat on the lower surface, so as to cook a pizza with better appearance and taste.

[0147] In other embodiments, the non-first cooking mode includes a preheating mode. In the preheating mode, the controller 6 is used to control the rotation speed of the fan 5 to be a preheating rotation speed, which is greater than the first rotation speed in the first cooking mode.

[0148] The cooking method includes a preheating mode and a first cooking mode. The first cooking mode may include a preheating mode. In the preheating mode, the controller 6 controls the fan 5 to run at a high speed so that the cooking cavity 11 can be quickly and evenly heated to complete the preheating, and then the pizza is placed in the cooking cavity 11, and finally the first cooking mode is used to cook the pizza.

[0149] The cooking method may also include the first cooking mode alone, the first cooking mode may not include the preheating mode, and the first cooking mode may complete the cooking of the pizza alone.

[0150] In other cooking methods, the cooking method includes a preheating mode and a non-first cooking mode, such as a cooking method including a preheating mode and a second cooking mode. The preheating mode can also be used as a preheating mode before one or more other non-first cooking modes, and after the preheating mode is completed, other non-first cooking modes are performed to meet the needs of food cooking.

[0151] The preheating mode setting allows food to start cooking in a higher temperature environment, which can speed up the cooking efficiency of food and improve the taste of some food.

[0152] In other embodiments, the non-first cooking mode includes one or more second cooking modes, wherein the plurality of second cooking modes are a plurality of other modes different from the first cooking mode, that is, the plurality of second cooking modes are a plurality of different cooking modes. The first cooking mode and the second cooking mode are used to cook at least one different food, for example, the first cooking mode is used to cook pizza, and the second cooking mode is used to cook other food besides pizza.

[0153] In the second cooking mode, the controller 6 is used to control the speed of the fan 5 to be a second speed, and the second speed is greater than the first speed in the first cooking mode. Among them, multiple second cooking modes have different second speeds, and multiple second speeds are all greater than the first speed.

[0154] For example, a second cooking mode is mainly used for cooking ordinary bread, which is mainly made of flour. In the second cooking mode, the fan 5 uses a second higher speed to blow the high-temperature air around the first heating element 3 to the top and around the bread, which can achieve faster and more efficient cooking and save cooking time.

[0155] Please refer to Figure 3 and Figure 4 In other embodiments, the cooking device further includes a first temperature sensor 7 and a second temperature sensor 8. The first temperature sensor 7 is installed in the cooking cavity 11 and is located above the carrier 2. The first temperature sensor 7 can be installed at the top of the cooking cavity 11 or a position close to the top. The second temperature sensor 8 is installed in the cooking cavity 11 and is located below the carrier 2. The second temperature sensor 8 can be installed at the bottom of the cooking cavity 11 or a position close to the bottom. The first temperature sensor 7 and the second temperature sensor 8 are located above and below the food, respectively. The first temperature sensor 7 is used to detect the temperature above the food and generate a first detection signal; the second temperature sensor 8 is used to detect the temperature below the food and generate a second detection signal.

[0156] The controller 6 is connected to the first temperature sensor 7 and the second temperature sensor 8 by signals respectively. The controller 6 is used to control the heating power and / or heating time of the first heating element 3 and the second heating element 4 according to the first detection signal and the second detection signal. The first temperature sensor 7 and the second temperature sensor 8 are used as real-time temperature feedback components. The controller 6 can obtain the temperature above and below the cooking cavity 11 in real time through the first temperature sensor 7 and the second temperature sensor 8 to achieve more accurate temperature control and improve the cooking effect.

[0157] For example, in the first cooking mode of cooking pizza, the controller 6 is used to control the temperature range under the food to be 200-210°C; when the second temperature sensor 8 detects that the temperature range under the food is 200-210°C, it is determined that the temperature is normal; when the second temperature sensor 8 detects that the temperature under the food is less than 200°C, or greater than 210°C, that is, when the temperature under the food is not in the range of 200-210°C, it is determined that the temperature is abnormal, and the controller 6 controls the second heating element 4 to reduce or increase the heating power accordingly to restore the temperature under the food to within 200-210°C.

[0158] In other embodiments, the first temperature sensor 7 and the second temperature sensor 8 may be provided in plurality, and the detection signals of the plurality of first temperature sensors 7 and the second temperature sensors 8 may be averaged to obtain a more accurate real-time temperature value. In addition, the provision of multiple sensors may eliminate detection errors or detection errors caused by abnormality of individual sensors, and may improve the accuracy of real-time temperature detection.

[0159] Please refer to Figure 5 In other embodiments, the cooking device is further provided with a first cooking mode button 9. The first cooking mode button 9 can be directly set on the outer side of the shell 1. The first cooking mode button 9 is a physical button. The first cooking mode button 9 is electrically connected to the controller 6. The first cooking mode button 9 is used to generate a first control signal. The controller 6 enters the first cooking mode according to the first control signal.

[0160] When the cooking device is in use, the user can directly enter the first cooking mode through the first cooking mode button 9 without going through multiple menu selections. The one-button operation is simple and efficient.

[0161] In other embodiments, when a touch screen is provided on the outer side of the cooking device, a virtual button for the first cooking mode is provided on the main menu of the touch screen, and the first cooking mode can be entered by one click through the virtual button, which is simple and efficient.

[0162] In other embodiments, the cooking device is further provided with physical buttons or virtual buttons for other cooking modes to efficiently and quickly enter other cooking modes. For example, a second cooking mode button is provided on the outside of the cooking device, and the second cooking mode button is connected to the controller 6 by signal. The second cooking mode button is used to generate a second control signal, and the controller 6 can enter the second cooking mode according to the second control signal.

[0163] In one embodiment, a cooking device is provided. The difference between the cooking device and the above cooking device is that: the first speed of the fan 5 in the first cooking mode is not limited to be not greater than the non-first speed of the fan 5 in the non-first cooking mode; and the cooking heat on the upper surface of the food is limited to be not greater than the cooking heat on the lower surface of the food in the first cooking mode. Such a setting can also improve the cooking effect of pizza compared with the existing cooking devices.

[0164] The controller 6 can control the heating time and / or heating power of the first heating element 3 and the second heating element 4 separately and independently.

[0165] In the first cooking mode, the controller 6 can control the first heating time of the first heating element 3 not to be greater than the second heating time of the second heating element 4; or the controller 6 can control the first heating power of the first heating element 3 not to be greater than the second heating power of the second heating element 4; or the controller 6 can control the first heating time of the first heating element 3 not to be greater than the second heating time of the second heating element 4, and the controller 6 can control the first heating power of the first heating element 3 not to be greater than the second heating power of the second heating element 4. The controller 6 controls the heating time and / or heating power of the first heating element 3 and the second heating element 4 respectively, and can control the heat generated by the first heating element 3 not to be greater than the heat generated by the second heating element 4, so that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food.

[0166] Among them, the first heating power of the first heating element 3 is not greater than the second heating power of the second heating element 4 includes: the average heating power of the first heating element 3 is not greater than the average heating power of the second heating element 4; or, at any time point within a certain time interval, the heating power of the first heating element 3 is not greater than the heating power of the second heating element 4.

[0167] The heating value of the first heating element 3 is controlled not to be greater than the heating value of the second heating element 4, and the temperature of the first contact medium of the food close to the first heating element 4 is also controlled not to be greater than the temperature of the second contact medium of the food close to the second heating element 4. The first contact medium is air, and the air layer in contact with the upper surface of the food heats and cooks the food; the second contact medium is a support member 2 or a placement structure such as a tray for placing the food in the support member 2. By controlling the temperature of the first contact medium to be not greater than the temperature of the second contact medium, it can be more accurately achieved that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food.

[0168] In the first cooking mode, the cooking heat generated on the upper surface of the food is not greater than the cooking heat generated on the lower surface of the food. This makes the cooking heat on the upper surface of the pizza not greater than the cooking heat on the lower surface of the pizza. The lower surface of the pizza has a smaller cooking heat, which can ensure that the toppings composed of vegetables, fruits, meat and other ingredients are cooked and not dried out or crispy, and have a better taste; while the lower surface of the pizza has a larger cooking heat, which can make the pizza bottom layer cooked and crispy, not only forming a three-dimensional support, not soft, but also having a better taste.

[0169] In the non-first cooking mode, the first heating element 3 and the second heating element 4 can be controlled separately, or can be controlled to heat synchronously or sequentially, the calorific value of the first heating element 3 and the calorific value of the second heating element 4 can be the same, or the calorific value of the first heating element 3 is not greater than the calorific value of the second heating element 4, or the calorific value of the first heating element 3 is greater than the calorific value of the second heating element 4. That is, in the non-first cooking mode, the heating order and calorific value of the first heating element 3 and the second heating element 4 can be controlled according to the cooking requirements of other foods.

[0170] In a non-first cooking mode, the controller 6 may also control one of the first heating element 3 and the second heating element 4 to heat, while the other one does not heat, so as to meet the cooking requirements of specific food.

[0171] The cooking device is provided with a first heating element 3 and a second heating element 4 which can be controlled separately. The first heating element 3 and the second heating element 4 are respectively arranged above and below the carrier. The second heating element located below can bake the pizza crust to a crispy state, which has a better appearance and taste. In addition, the heat generated by the first heating element 3 is not greater than the heat generated by the second heating element 4, so that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food, and the cooking heat on the upper surface of the pizza is not greater than the cooking heat on the lower surface, so as to cook a pizza with a better appearance and taste.

[0172] In one embodiment, a cooking method is provided, and the cooking method uses the cooking device in the above embodiment to achieve cooking. The difference between the cooking method and the above cooking method is that: the first speed of the fan 5 in the first cooking mode is not limited to be not greater than the non-first speed of the fan 5 in the non-first cooking mode; and the cooking heat on the upper surface of the food is limited to be not greater than the cooking heat on the lower surface of the food in the first cooking mode. Such a setting can also improve the cooking effect of pizza compared with the existing cooking method.

[0173] Please refer to Figure 7 The cooking method is executed by the controller 6 of the cooking device, and the cooking method mainly includes the following steps:

[0174] S21: Select a cooking mode according to the control signal;

[0175] A control signal is acquired, and the cooking device is controlled to enter a first cooking mode or a non-first cooking mode according to the control signal.

[0176] The user can select the first cooking mode or the non-first cooking mode through the buttons or interface menu of the cooking device. When the user selects the first cooking mode, a first control signal is generated, and the controller 6 obtains the first control signal and controls the cooking device to enter the first cooking mode to cook food; when the user selects the non-first cooking mode, a non-first control signal is generated, and the controller 6 obtains the non-first control signal and controls the cooking device to enter the non-first cooking mode; for example, when the user selects the second cooking mode, a second control signal is generated, and the controller 6 obtains the second control signal and controls the cooking device to enter the second cooking mode.

[0177] When the cooking device is provided with a first cooking mode button 9, after the user presses the first cooking mode button 9, the first cooking mode button 9 generates a first control signal, the controller 6 obtains the first control signal, and controls the cooking device to enter the first cooking mode to cook food. Entering the first cooking mode through the operation of the first cooking mode button 9 is simple and efficient, and has a better user experience.

[0178] S22: Entering a cooking mode, in which the cooking heat generated on the upper surface of the food in the first cooking mode is not greater than the cooking heat generated on the lower surface of the food.

[0179] The controller 6 controls the cooking device to enter different cooking modes according to different control signals obtained.

[0180] In the first cooking mode, the controller 6 controls the first heating element 3 and the second heating element 4 to heat, and controls the fan 5 to transfer the heat generated by the first heating element 3 to the cooking cavity 11. The fan 5 can also drive the heat generated by the second heating element 4 to transfer to the cooking cavity 11 to cook food. The fan 5 drives the air in the cooking cavity 11 to flow, so as to drive the heat generated by the first heating element 3 and the second heating element 4 to flow in the cooking cavity 11 to cook food.

[0181] In the non-first cooking mode, the controller 6 controls one or both of the first heating element 3 and the second heating element 4 to heat, and controls the fan 5 to transfer the heat generated by one or both of the first heating element 3 and the second heating element 4 to the cooking cavity 11 to cook food.

[0182] In the cooking method, in the first cooking mode, the controller 6 controls the heating value of the first heating element 3 to be not greater than the heating value of the second heating element 4, so as to improve the cooking effect of the pizza.

[0183] The controller 6 can control the heating time and / or heating power of the first heating element 3 and the second heating element 4 separately and independently.

[0184] In the first cooking mode, the controller 6 can control the first heating time of the first heating element 3 not to be greater than the second heating time of the second heating element 4; or the controller 6 can control the first heating power of the first heating element 3 not to be greater than the second heating power of the second heating element 4; or the controller 6 can control the first heating time of the first heating element 3 not to be greater than the second heating time of the second heating element 4, and the controller 6 can control the first heating power of the first heating element 3 not to be greater than the second heating power of the second heating element 4. The controller 6 controls the heating time and / or heating power of the first heating element 3 and the second heating element 4 respectively, and can control the heat generated by the first heating element 3 not to be greater than the heat generated by the second heating element 4, so that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food.

[0185] Among them, the first heating power of the first heating element 3 is not greater than the second heating power of the second heating element 4 includes: the average heating power of the first heating element 3 is not greater than the average heating power of the second heating element 4; or, at any time point within a certain time interval, the heating power of the first heating element 3 is not greater than the heating power of the second heating element 4.

[0186] The heating value of the first heating element 3 is controlled not to be greater than the heating value of the second heating element 4, and the temperature of the first contact medium of the food close to the first heating element 4 is also controlled not to be greater than the temperature of the second contact medium of the food close to the second heating element 4. The first contact medium is air, and the air layer in contact with the upper surface of the food heats and cooks the food; the second contact medium is a support member 2 or a placement structure such as a tray for placing the food in the support member 2. By controlling the temperature of the first contact medium to be not greater than the temperature of the second contact medium, it can be more accurately achieved that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food.

[0187] In the first cooking mode, the cooking heat generated on the upper surface of the food is not greater than the cooking heat generated on the lower surface of the food. This makes the cooking heat on the upper surface of the pizza not greater than the cooking heat on the lower surface of the pizza. The lower surface of the pizza has a smaller cooking heat, which can ensure that the toppings composed of vegetables, fruits, meat and other ingredients are cooked and not dried out or crispy, and have a better taste; while the lower surface of the pizza has a larger cooking heat, which can make the pizza bottom layer cooked and crispy, not only forming a three-dimensional support, not soft, but also having a better taste.

[0188] In the non-first cooking mode, the first heating element 3 and the second heating element 4 can be controlled separately, or can be controlled to heat synchronously or sequentially, the calorific value of the first heating element 3 and the calorific value of the second heating element 4 can be the same, or the calorific value of the first heating element 3 is not greater than the calorific value of the second heating element 4, or the calorific value of the first heating element 3 is greater than the calorific value of the second heating element 4. That is, in the non-first cooking mode, the heating order and calorific value of the first heating element 3 and the second heating element 4 can be controlled according to the cooking requirements of other foods.

[0189] In a non-first cooking mode, the controller 6 may also control one of the first heating element 3 and the second heating element 4 to heat, while the other one does not heat, so as to meet the cooking requirements of specific food.

[0190] In the cooking method, the controller 6 can independently control the first heating element 3 and the second heating element 4, and control the heating value of the first heating element 3 not to be greater than the heating value of the second heating element 4, so that the cooking heat formed on the upper surface of the food is not greater than the cooking heat formed on the lower surface of the food, and the cooking heat on the upper surface of the pizza is not greater than the cooking heat on the lower surface, so as to cook a pizza with better appearance and taste; and, the upper and lower parts of the pizza can be in a relatively good cooking state at the same time when the cooking is finished.

[0191] In one embodiment, please refer to Figure 8-Figure 18 The pot body 100 has a cooking cavity 110, and the first heating tube 200 is arranged at the top of the pot body 100. The second heating tube 300 is arranged at the bottom of the pot body 100. The first heating tube 200 and the second heating tube 300 are used to generate heat when powered on to heat the air and the pot body 100, and the fan 400 is used to drive the hot air flow to circulate in the cooking cavity 110. Among them, the second heating tube 300 forms a ring structure 310 with at least two circles. The food carrier 500 is arranged in the pot body 100, and the first heating tube 200 and the second heating tube 300 are respectively arranged on both sides of the food carrier 500 to heat the food from different directions.

[0192] On the one hand, since the second heating tube 300 forms at least two circles of the annular structure 310, the density is higher than that of a single circle of the annular structure, so that the heat generated by the second heating tube 300 can be more evenly transferred to the bottom of the food carrier 500, thereby making the temperature of different areas at the bottom of the food carrier 500 more uniform. On the other hand, compared with a single circle of the heating tube, the formation of at least two circles of the annular structure 310 makes the second heating tube 300 have a longer line length under the same line diameter and plane outer diameter, which is conducive to improving the power of the second heating tube 300. The first heating tube 200 and the second heating tube 300 generate heat from the top and bottom of the pot body 100 respectively, which is conducive to improving the heating efficiency of the cooking device, and is conducive to reducing the temperature difference between the top and the bottom of the pot body 100, and is also conducive to quickly heating the front and back sides of the food carried on the food carrier 500, taking away moisture, so as to achieve rapid charring and crisping of the food.

[0193] It should be noted that the plane outer diameter of the second heating tube 300 can be understood as the diameter of the outermost annular structure 310 of the second heating tube 300. The line length of the second heating tube 300 can be understood as the sum of the circumference of all its annular structures 310 and the line length of the transition part between all the annular structures 310. Specifically, Fig.11 The plane outer diameter of the second heating tube 300 can be regarded as Fig.11 The line segment R1 in Fig.11 The length of the second heating tube 300 can be regarded as Fig.11 The sum of the circumference of the first annular structure 311, the second annular structure 312 and the third annular structure 313 and the line length of the transition part between them. The line diameter of the second heating tube 300 can be understood as the diameter of the cross section of the second heating tube 300. The temperature of different areas at the bottom of the pot body 100 or the food carrier 500 is more uniform, which can be understood as the temperature difference of different areas at the bottom of the pot body 100 or the food carrier 500 is smaller.

[0194] Please refer to Figure 11-Figure 17 In one embodiment, at least two ring structures 310 are sequentially arranged along a direction from the center to the periphery of the second heating tube 300 .

[0195] The annular structure 310 located at the periphery of the second heating tube 300 surrounds the annular structure 310 located at the interior, that is, the tube body 320 of the second heating tube 300 is more evenly distributed in the interior and exterior spaces, so that the heat generated by the second heating tube 300 can be more evenly transferred to the bottom of the pot body 100, thereby making the temperature of different areas at the bottom of the pot body 100 more uniform.

[0196] Specifically, please refer to Fig.10 , Fig.12 and Fig.14In this embodiment, the second heating tube 300 forms a two-ring annular structure 310. Please refer to Fig.11 , Fig.13 and Fig.15 In other embodiments, the second heating pipe 300 may also be a ring structure 310 having three or more circles. The ring structure 310 is configured as a circular ring structure or a polygonal structure. For example, please refer to Fig.12 and Fig.13 The polygonal structure may be a quadrilateral, a pentagon, a hexagon or other suitable shapes.

[0197] Please refer to Figure 11-13 In one embodiment, the second heat pipe 300 includes a single tube body 320, a portion of the single tube body 320 forms an annular structure 310 located at the periphery, and another portion of the single tube body 320 is bent inward to form an annular structure 310 located at the inside.

[0198] By bending a single tube body 320 to form at least two turns of the annular structure 310, on the one hand, the power line of the single tube body 320 is simpler, which is conducive to reducing the difficulty of wiring operation and the failure rate of the power line. On the other hand, the processing cost, quality control and installation cost of the single tube body 320 are lower. Of course, in other embodiments, the second heating tube 300 can also include two or more tube bodies 320.

[0199] Please refer to Figure 11-13 In one embodiment, the second heating tube 300 has a first end 330 and a second end 340, and a single tube body 320 extends from the first end 330 to the second end 340. The second heating tube 300 has a first side 350 and a second side 360 ​​that are oppositely disposed, and the first end 330 and the second end 340 are both located on the first side 350. The annular structure 310 includes a first annular structure 311 and a second annular structure 312, the first annular structure 311 is located at the outermost periphery of the tube body 320, and the first annular structure 311 is bent inward from the middle of the second side 360 ​​to form the second annular structure 312.

[0200] On the one hand, the first end 330 and the second end 340 are both located on the first side 350, so that the first side 350 of the second heating tube 300 can be easily installed in the pot body 100, and the circuit connection can be realized on the first side 350 of the second heating tube 300. On the other hand, the first annular structure 311 is bent inward from the middle of the second side 360 ​​to form the second annular structure 312, so that the first annular structure 311 and the second annular structure 312 are an integrated structure, which is conducive to reducing the processing cost, quality control and installation cost of the second heating tube 300.

[0201] Please refer to Fig.11 and Fig.13In one embodiment, the annular structure 310 further includes a third annular structure 313 , and the second annular structure 312 is bent inward from the middle toward one side of the first end 330 and the second end 340 to form the third annular structure 313 .

[0202] On the one hand, the first annular structure 311, the second annular structure 312 and the third annular structure 313 are nested in sequence from the periphery to the center. On the other hand, the first annular structure 311, the second annular structure 312 and the third annular structure 313 form an integrated structure, which is conducive to reducing the processing cost, quality control and installation cost of the second heating pipe 300. Of course, in other embodiments, the second heating pipe 300 may also include a larger number of annular structures 310, for example, the second tube body 320 may also include a fourth annular structure.

[0203] Please refer to Fig.14 and Fig.15 In one embodiment, the second heat pipe 300 includes at least two tube bodies 320, each tube body 320 forms at least one annular structure 310, and the annular structures 310 formed by at least two tube bodies 320 are nested in sequence along the direction from the center to the periphery of the second heat pipe 300.

[0204] The second heating tube 300 is formed by a plurality of tube bodies 320. For example, please refer to Fig.14 The second heating tube 300 may include two tube bodies 320, each tube body 320 forms an annular structure 310, and the two annular structures 310 are nested in sequence from the periphery to the center. Fig.15 The second heat pipe 300 may further include three tube bodies 320, and three annular structures 310 are formed by the three tube bodies 320 in a one-to-one correspondence, and the three annular structures 310 are nested in sequence from the periphery to the center. Of course, among the at least two tube bodies 320 included in the second heat pipe 300, the annular structure 310 formed by a single tube body 320 is not limited to one. For example, two annular structures 310 may be formed by a single tube body 320, and then the two annular structures 310 are nested and combined with the annular structure 310 formed by another tube body 320.

[0205] Please refer to Fig.16 In one embodiment, the radial dimension of the outermost annular structure 310 in the second heating tube 300 is not less than the radial dimension of the first heating tube 200 .

[0206] The radial dimension of the largest annular structure 310 in the second heating tube 300 is smaller than the radial dimension of the first heating tube 200, which is suitable for the allocation of the installation space at the top and bottom of the pot body 100, and the distance between the first heating tube 200 and the second heating tube 300 and the food in the pot body 100. That is, by reasonably designing the radial dimensions of the first heating tube 200 and the second heating tube 300, it is beneficial to realize the efficient use of the installation space in the cooking device and improve the cooking effect of the cooking device on the food.

[0207] It should be noted that the “radial dimension” of the annular structure 310 may be the length of the line between the two farthest points in the figure formed by the annular structure 310 in the plane. For example, when the annular structure 310 is a circular ring structure, its radial dimension is the diameter of the circular ring. When the circular ring structure is a polygon, its radial dimension is the length of the longest diagonal line in the polygon.

[0208] Please refer to Figure 8 and Fig.16 In one embodiment, the cooking device further comprises a food carrier 500, the food carrier 500 is used to carry food in the cooking cavity 110, and the ratio of the radial dimension of the first annular structure 311 to the radial dimension of the bottom of the food carrier 500 is not less than 1:2. The ratio of the radial dimension of the second annular structure 312 to the radial dimension of the bottom of the food carrier 500 is not less than 3:7. Preferably, the ratio of the radial dimension of the first annular structure 311 to the radial dimension of the bottom of the food carrier 500 is not less than 3:4. The ratio of the radial dimension of the second annular structure 312 to the radial dimension of the bottom of the food carrier 500 is not less than 3:7.

[0209] On the one hand, when using the cooking device, the user can carry and take out the food in the cooking device through the food carrier 500, so as to facilitate the use of the customer. On the other hand, by reasonably designing the radial dimensions of the first annular structure 311, the second annular structure 312 and the radial dimensions of the bottom of the food carrier 500, the heat emitted by the second heating tube 300 can be more efficiently and evenly transferred to different areas at the bottom of the food carrier 500, which is conducive to improving the cooking effect of the cooking device on the food in the food carrier 500. Specifically, the food carrier can be a frying basket, a grill or other structure that can carry food. Of course, in other embodiments, the cooking device may not include the food carrier 500, but directly place the food into the pot body 100.

[0210] In some embodiments, please refer to Figure 17 to Figure 18The blades of the fan 5 include a fan blade 52 and a base 51. The fan blade 52 includes a windward surface 221 and a leeward surface 222. Both the windward surface 221 and the leeward surface 222 are located on the fan blade portion. The fan 5 mainly relies on the driving effect of the windward surface 221 on the hot air flow to stir the hot air flow and promote the circulation of hot air in the furnace cavity.

[0211] Please continue to refer to Figure 17 to Figure 18 The chassis 51 has an outer tangent surface TT" corresponding to the windward surface 221, the windward surface 221 or an extended surface of the windward surface 221 intersects with the outer peripheral surface of the chassis 51 and has an intersection line, the outer tangent surface TT" on the chassis 51 corresponding to the windward surface 221 passes through the intersection line, and the outer tangent surface TT" is tangent to the outer peripheral surface of the chassis 51; the angle between the windward surface 221 and the outer tangent surface TT" of the chassis 51 is set to 90°±20°, so that when the hot air fan blade assembly rotates, the effective action area of ​​the fan blade 52 for pushing the hot air flow in the rotation direction to realize the hot air flow circulation is similar to the area of ​​the windward surface 221, which can reduce the material consumption of the fan blade 52 while improving the stirring efficiency of the fan blade 52 on the hot air flow, and improve the uniformity of the hot air circulation in the furnace cavity, thereby improving the cooking effect and cooking rate.

[0212] As an example, please refer to Fig.18 The fan blade 52 has a center plane OO", which is a plane. The center plane OO" is extended in the radial direction of the chassis 51, and the extension plane of the center plane OO" passes through the central axis of the chassis 51. The thickness of the fan blade portion in the fan blade 52 is equal everywhere in the radial direction of the chassis 51, the windward surface 221 and the leeward surface 222 are both parallel to the center plane OO", and the angle between the windward surface 221 and the outer tangent surface TT" corresponding to the windward surface 221 is 87° or 93°. In another embodiment, the thickness of the fan blade portion in the fan blade 52 gradually increases from the center of the chassis 51 to the outer peripheral surface of the chassis 51 in the radial direction of the chassis 51, the windward surface 221 and the leeward surface 222 have an angle less than 90° with the center plane OO", and the angle between the windward surface 221 and the outer tangent surface TT" corresponding to the windward surface 221 is 89° or 91°. In another embodiment, the thickness dimension of the fan blade portion in the fan blade 52 gradually decreases from the center of the chassis 51 to the outer peripheral surface of the chassis 51 in the radial direction of the chassis 51, and the windward surface 221 and the leeward surface 222 both have an angle less than 90° with the center plane OO", and the angle between the windward surface 221 and the circumferential surface TT" corresponding to the windward surface 221 is 84° or 96°. In other embodiments, the extension surface of the center plane OO" or the windward surface 221 may not pass through the central axis of the chassis 51, and an angle is formed between the center plane OO" or the windward surface 221 and the diameter of the chassis 51, but it is sufficient that the angle between the windward surface 221 and the corresponding circumferential surface TT" is 90°±20°.

[0213] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
