Description

Technical Field

[0001] This application relates to the field of cooking utensil technology, and more specifically, to a cooking utensil. Background Technology

[0002] Currently, cooking equipment uses heating elements to cook the food inside, and the heat field generated by the heating elements plays an indispensable role in the cooking process.

[0003] However, currently, due to the limited placement of the heating element, the heat field inside the cooking equipment is not uniform enough, resulting in inconsistent cooking effects for ingredients in different locations. This inability to obtain uniform heat directly affects the cooking performance of the equipment. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the first aspect of this application is to propose a cooking utensil.

[0006] In view of the above, according to the first aspect of this application, a cooking appliance is provided, which includes a housing, a ventilation assembly and at least one heating element. The housing has a cooking cavity, the ventilation assembly is disposed in the housing and is used to circulate gas in the cooking cavity, and the heating element is disposed in the housing and is used to heat the gas in the cooking cavity. Each heating element includes N heating segments, and at least two of the N heating segments have different heating powers, where N is an integer greater than or equal to 2.

[0007] The cooking appliance provided in this application includes a housing, a ventilation assembly, and a heating element. The housing has a cooking cavity for holding food. The ventilation assembly and the heating element are mounted on the housing. The housing not only forms a space for holding the food but also serves to mount and fix the ventilation assembly and the heating element. The heating element heats the airflow within the cooking cavity, thereby forming a hot airflow. The ventilation assembly can agitate the airflow within the cooking cavity, making the hot airflow more evenly distributed within the cooking cavity and improving the heating uniformity of the cooking appliance.

[0008] The heating element comprises N heating segments, at least two of which have different heating powers; that is, the heating powers of the multiple heating segments are not entirely the same. The heating segments with different heating powers can be configured according to the airflow distribution within the cooking cavity. In areas where heat is concentrated, heating segments with lower power can be used, while in areas where heat is more dispersed, heating segments with higher power can be used. This prevents food in areas with concentrated heat from being overheated and burning, and also prevents food in areas with dispersed heat from not receiving enough heat to be properly cooked.

[0009] This application utilizes heating sections with varying heating powers within the cooking appliance to complement the heat field generated by the heating element and the airflow generated by the air supply component. This enhances the uniformity of heat distribution throughout the cooking cavity, increases heating speed, and improves cooking results. The different heating sections within the heating element can provide adaptive heat compensation to different locations, further improving the uniformity of the heat field within the cooking cavity.

[0010] Specifically, for localized areas where the airflow is difficult to reach, resulting in insufficient heat, the heating power of the corresponding heating element in that area can be increased. Conversely, for localized areas where the airflow is easy to reach, resulting in excessive heat, the heating power of the corresponding heating element in that area can be decreased. In this way, the heat field formed by the heating element and the airflow field formed by the air supply component can complement each other, achieving a uniform distribution of heat within the cooking cavity, improving the cooking effect of the cooking appliance, and accelerating cooking efficiency.

[0011] In one possible design, the resistivity of the two heating sections is different. And / or, the lengths of the two heating sections are different. And / or, the cross-sectional areas of the two heating sections are different.

[0012] In this design, the formula for calculating the heating power for the heating section's heating efficiency is P = U. 2 / R, where P represents heating power, U represents voltage, and R represents resistance. According to the formula for calculating heating power, under the same voltage, changing the resistance will change the heating power. The formula for calculating resistance is R = ρL / S, where R represents resistance, ρ represents resistivity, L represents the length of the resistor, and S represents the cross-sectional area of ​​the resistor. According to the formula for calculating resistance, changing at least one of the resistivity, length, or cross-sectional area of ​​a resistor will change its resistance.

[0013] Therefore, this application ensures that the heating power of the heating sections is not completely the same by setting at least two heating sections with different resistivity and / or length and / or cross-sectional area. When the heating element heats any surface (the surface of a cookware, baking tray, or other device), the heating conditions of that surface are different. While ensuring a simple structure and not increasing costs, it can meet specific heating requirements and improve the flexibility of heating.

[0014] In this case, for the same heating element, at least two heating sections are connected in series, which simplifies the structure of the heating element and improves the convenience of controlling the heating element.

[0015] It is worth noting that when there are multiple heating sections connected in series, the heating power of these sections does not necessarily need to show a continuous increasing or decreasing trend from one end of the heating element to the other, as long as it can complement the wind field. For example, when there are three heating sections, the heating power corresponding to the three connected sections are P1, P2, and P3. The relationship between them can be P1 < P2, P3 < P2, that is, showing a trend of first increasing and then decreasing.

[0016] In one possible design, the heating element further includes a heating tube.

[0017] In this design, the heating element includes a heating tube, which comprises a tube body and a heating wire. The heating wire is inserted into the tube body, which protects the heating wire from damage. The heating wire can be divided into several segments of different lengths according to certain parameter requirements. The heating power of each segment is not exactly the same, allowing a single heating source (single heating element) to meet different heating needs simultaneously, thus improving the flexibility of the heating element setup. It should be noted that the heating tube can be a metal tube, which generates heat to heat the air when energized. Alternatively, the heating tube can be a radiant heating tube, which generates light radiation to heat food.

[0018] It is worth noting that the heating element can be bent and deformed according to the needs of cooking appliances, thus adapting to various installation requirements.

[0019] In one possible design, the heating element further comprises a graphene tube.

[0020] In this design, the heating wire in the heating element is made of graphene, which improves the heating speed and heating efficiency. When the cooking appliance uses a graphene tube, it eliminates the need for preheating, allowing the cooking temperature to rise rapidly, shortening cooking time and meeting diverse user cooking needs.

[0021] In one possible design, the housing further includes a perimeter panel, a top panel, and a bottom panel. A first vent is provided on the perimeter panel, and an air supply assembly is disposed on the outside of the cooking cavity corresponding to the first vent. The top panel is connected to the top of the perimeter panel. The bottom panel is connected to the bottom of the perimeter panel, and the cooking cavity is located between the perimeter panel, the top panel, and the bottom panel.

[0022] In this design, the shell includes a connected enclosure, a top plate, and a bottom plate. The top plate is connected to the top of the enclosure, and the bottom plate is connected to the bottom of the enclosure. The three plates are connected and enclose the cooking cavity. The cross-section of the enclosure is approximately U-shaped. A first vent is provided on the enclosure, which connects the cooking cavity to the outside. An air supply component is correspondingly located at the first vent. When the air supply component is working, it can create a pressure field, causing the airflow inside the cooking cavity to surge, and also allowing the airflow to circulate inside and outside the cooking cavity. The first vent is an air inlet.

[0023] Furthermore, the air supply component is located on the outside of the cooking cavity, meaning that the air supply component does not occupy space inside the cooking cavity, thus providing a larger cooking cavity to meet the user's cooking needs.

[0024] In one possible design, the heating element further includes a first heating element connected to the top plate, at least a portion of which is located within the cooking cavity.

[0025] In this design, the heating element includes a first heating element connected to the top plate, i.e., the first heating element is located on the upper side of the cooking cavity. The first heating element is mainly used to heat the air at the top of the cooking cavity. Since the air temperature in the middle of the cooking cavity is higher than that on the sides, the arrangement of at least two heating sections of the first heating element allows the heating sections with higher heating power to be placed on the sides, and the heating sections with lower heating power to be placed in the middle.

[0026] Furthermore, at least a portion of the first heating element is located inside the cooking cavity, thereby enabling direct heating of the gas inside the cooking cavity and reducing heat loss.

[0027] In one possible design, the heating element further includes a second heating element, which is located on the side of the base plate opposite to the first heating element.

[0028] In this design, the heating element also includes a second heating element located at the bottom of the cooking cavity. Specifically, the second heating element is positioned on the outside of the cooking cavity, i.e., under the bottom plate. When food is being cooked inside the cooking cavity, some food residue or oil stains may fall down. If the second heating element were located at the bottom of the cooking cavity, food residue or oil stains would easily damage it, directly affecting its normal performance. By placing the second heating element at the bottom of the bottom plate, the heating effect on the airflow at the bottom of the cooking cavity is not affected, while the lifespan of the second heating element is extended, and safety and hygiene during the cooking process are ensured.

[0029] It should be noted that the first heating element comprises N heating segments, and at least two of these segments have different heating powers, where N is an integer greater than or equal to 2. Similarly, the second heating element also comprises N heating segments, and at least two of these segments have different heating powers, where N is an integer greater than or equal to 2. For both the first and second heating elements, the heating powers of at least two heating segments within each heating element can be completely different or not completely the same. Furthermore, the trends in the heating power variations of multiple heating segments in both the first and second heating elements can be the same or different.

[0030] In one possible design, the number of first heating elements is at least two, and the at least two first heating elements are arranged at intervals.

[0031] In this design, when there are at least two first heating elements, the area that can be adjusted by at least two first heating elements is larger, thereby quickly compensating for areas with less heat in the cooking cavity and reducing heat transfer to areas with more heat in the cooking cavity, thus achieving rapid and uniform heat distribution in the cooking cavity.

[0032] In one possible design, the number of second heating elements is further specified as at least two, with the at least two second heating elements arranged at intervals.

[0033] In this design, when there are at least two second heating elements, the area that can be adjusted by at least two second heating elements is larger, thereby quickly compensating for areas with less heat in the cooking cavity and reducing heat transfer to areas with more heat in the cooking cavity, thus achieving rapid and uniform heat distribution in the cooking cavity.

[0034] In this design, one first heating element can extend along the left-right direction and be disposed on the housing, while multiple first heating elements can be arranged side by side along the front-back direction. Alternatively, one first heating element can extend along the front-back direction and be disposed on the housing, while multiple first heating elements can be arranged side by side along the left-right direction. Alternatively, multiple first heating elements can be arranged in a staggered manner, for example, one first heating element extends along the left-right direction and another first heating element extends along the front-back direction, with the two staggered at the top of the cooking cavity.

[0035] Similarly, the arrangement of the second heating element can refer to the arrangement of the first heating element. The two can be arranged in the same direction or in different directions, depending on the actual needs.

[0036] In one possible design, the number of first heating elements is greater than the number of second heating elements.

[0037] In this design, the first heating element is the top heat source, and the second heating element is the bottom heat source. When the food is placed in the cooking cavity, it is usually placed on tableware. The first heating element, located above the food, can directly heat the food, while the second heating element, located below the food, will be blocked by the tableware. That is, the heating effect of the first heating element is more important than that of the second heating element. By making the number of first heating elements greater than the number of second heating elements, the cooking effect of the food can be ensured while also saving costs to a certain extent.

[0038] In one possible design, the housing further includes a second vent located on the enclosure panel, and the air supply assembly enables airflow to circulate between the first vent, the cooking cavity, and the second vent.

[0039] In this design, the enclosure includes a back panel, a first vent on the back panel, a second vent on the back panel, and an air supply assembly that can be fixed to the back panel. When the air supply assembly is working, the airflow can enter the cooking cavity through the first vent. Under the action of the heating element, the hot airflow heats the food. A portion of the airflow will flow from the second vent to the outside of the cooking cavity and then be guided back into the cooking cavity by the air supply assembly, thereby realizing the airflow circulation of the cooking appliance.

[0040] In one possible design, the enclosure further includes side panels connected to both sides of the back panel, and a first vent can also be located on either of the two side panels. A second vent can also be located on either of the two side panels.

[0041] It should be noted that the first and second vents can be simultaneously located on the back panel or the side panel, with one of the first and second vents located on the side panel and the other on the back panel. In one possible design, a portion of the bottom panel is further recessed away from the top panel.

[0042] In this design, a portion of the base plate is recessed downwards to form a guide groove. During the cooking process, food residue or oil stains will fall downwards, and the guide groove is used to collect the residue, oil stains, etc., so that they gather in the middle of the base plate, making it convenient for users to clean.

[0043] In one possible design, the air supply assembly further includes a drive unit and fan blades. The drive unit is mounted on the housing, and the fan blades are connected to the drive unit. The drive unit can drive the fan blades to rotate, thereby disturbing the gas flow inside the cooking cavity.

[0044] In this design, the air supply assembly includes a drive unit and fan blades. The drive unit is detachably mounted on the housing and serves as the power output component. The fan blades are connected to the drive unit, which drives the fan blades to rotate. The rotation of the fan blades creates a pressure field at the first vent, thereby disturbing the gas flow within the cooking cavity. The design is simple and inexpensive.

[0045] In one possible design, the drive element further includes a drive motor, the output shaft of which is connected to the fan blades.

[0046] In this design, the drive unit includes a drive motor, which includes a connected drive motor and an output shaft. The drive motor is fixed on the housing, and the output shaft is connected to the fan blades. The output shaft and the fan blades can rotate synchronously relative to the drive motor.

[0047] In one possible design, the cooking appliance further includes a heating element disposed on the housing, located between the air supply assembly and the housing.

[0048] In this design, the cooking appliance also includes a heating element mounted on the housing and located on one side of the air supply assembly. The heating element heats the gas about to enter the cooking chamber, ensuring that the airflow blown into the cooking chamber through the first vent is hot air. The air supply assembly and the heating element together constitute a hot air assembly, further improving the heating efficiency of the cooking appliance. In other words, the cooking appliance not only has a first heating element and a second heating element located vertically, but also a heating element located at the rear of the cooking chamber. These three heating elements provide heat to the food from three directions. When the heating element and the air supply assembly work together to input hot air into the cooking cavity, the airflow distribution within the cavity is uneven. Areas easily reached by the airflow are areas of concentrated heat, while areas difficult to reach are areas of insufficient heat. The heating element can be configured to adjust the heat distribution in different zones, with lower power for the heating sections in areas of concentrated heat and higher power for those in areas of insufficient heat. This results in a more uniform heat distribution throughout the cooking cavity, thereby improving cooking performance and efficiency.

[0049] In one possible design, the heating element further includes a heating tube arranged around the air supply assembly.

[0050] In this design, the heating element includes a heating tube, which is bent to form an annular coil. The central area of ​​the annular coil has a receiving area, and part of the air supply component can be located in this receiving area. This allows for a more rational and centralized arrangement of the heating element and the air supply component, reducing the space occupied by them in the front-to-back direction and making the overall size of the cooking appliance smaller, thus adapting to the trend of product miniaturization.

[0051] In one possible design, the cooking appliance further includes a storage unit, which is detachably mounted on the housing and located inside the cooking cavity. The storage unit is used to place food ingredients.

[0052] In this design, the cooking appliance also includes a storage unit, which is detachably mounted on the housing and located inside the cooking cavity. Food ingredients can be placed on the storage unit, and users can retrieve the food ingredients through the storage unit.

[0053] When the cooking appliance is an oven, the items placed on it can be a baking tray, a grill rack, etc.

[0054] When the cooking appliance is an air fryer, the container can be a frying basket or similar item.

[0055] In one possible design, the cooking appliance further includes an oven.

[0078] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0079] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0080] The following reference Figures 1 to 8 This application describes a cooking appliance 100 provided according to some embodiments.

[0081] According to the first aspect of this application, a cooking utensil 100 is provided, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the cooking appliance 100 includes a housing 110, a ventilation assembly 120, and at least one heating element 130. The housing 110 has a cooking cavity 111. The ventilation assembly 120 is disposed on the housing 110 and causes gas to flow in the cooking cavity 111. At least one heating element 130 is disposed on the housing 110 and is used to heat the gas in the cooking cavity 111. Each heating element 130 includes N heating segments 131, and at least two of the N heating segments 131 have different heating powers, where N is an integer greater than or equal to 2.

[0082] The cooking appliance 100 provided in this application includes a housing 110, an air supply assembly 120, and a heating element 130. The housing 110 has a cooking cavity 111 for accommodating food. The air supply assembly 120 is disposed on the housing 110, and the heating element 130 is disposed on the housing 110. The housing 110 not only forms a space for accommodating food but also serves to mount and fix the air supply assembly 120 and the heating element 130. The heating element 130 is used to heat the airflow within the cooking cavity 111, thereby forming a hot airflow. The air supply assembly 120 can agitate the airflow within the cooking cavity 111, making the hot airflow more evenly distributed within the cooking cavity 111 and improving the heating uniformity of the cooking appliance 100.

[0083] The heating element 130 includes at least two heating sections 131, and at least two of the heating sections 131 have different heating powers. That is, the heating powers of the multiple heating sections 131 are not completely the same. The heating sections 131 with different heating powers can be set according to the distribution of the airflow in the cooking cavity 111. In areas where the heat is more concentrated, heating sections 131 with lower heating powers can be set, and in areas where the heat is more dispersed, heating sections 131 with higher heating powers can be set. This avoids the food in areas with concentrated heat being heated to an excessively high temperature and burning, and avoids the food in areas with dispersed heat not receiving enough heat and failing to be cooked.

[0084] In this application, by setting heating sections 131 with different heating powers within the cooking appliance, the heat field generated by the heating element 130 and the air field formed by the air supply assembly 120 can complement each other, improving the uniformity of heat distribution within the entire cooking cavity 111, increasing heating speed, and improving cooking results. The heating sections 131 with different heating powers in the heating element 130 can provide adaptive heat compensation to different locations, improving the uniformity of the heat field within the cooking cavity 111.

[0085] Specifically, for local areas where the wind is difficult to reach and the heat is too low, the heating power of the corresponding heating section 131 can be increased. Conversely, for local areas where the wind is easy to reach and the heat is too high, the heating power of the corresponding heating section 131 can be decreased. In this way, the heat field formed by the heating element 130 and the wind field formed by the air supply component 120 can complement each other, achieving a uniform distribution of heat in the cooking cavity 111, improving the cooking effect of the cooking appliance 100, and accelerating the cooking efficiency.

[0086] Furthermore, such as Figure 6 , Figure 7 and Figure 8 As shown, the resistivity of the two heating segments 131 is different. And / or, the lengths of the two heating segments 131 are different. And / or, the cross-sectional areas of the two heating segments 131 are different.

[0087] In this embodiment, the formula for calculating the heating power for the heating efficiency of the heating section 131 is P = U. 2 / R, where P represents heating power, U represents voltage, and R represents resistance. According to the formula for calculating heating power, under the same voltage, changing the resistance will change the heating power. The formula for calculating resistance is R = ρL / S, where R represents resistance, ρ represents resistivity, L represents the length of the resistor, and S represents the cross-sectional area of ​​the resistor. According to the formula for calculating resistance, changing at least one of the resistivity, length, or cross-sectional area of ​​a resistor will change its resistance.

[0088] Therefore, by setting at least two heating sections 131 with different resistivity and / or length and / or cross-sectional area, this application ensures that the heating power of the heating sections 131 is not completely the same. When the heating element 130 heats any surface, such as the surface of a cookware, baking tray, or other device, the heating conditions of that surface are different. While ensuring a simple structure and not increasing costs, it can meet specific heating requirements and improve the flexibility of heating.

[0089] Furthermore, in at least two heating segments 131, the resistivity and / or length and / or cross-sectional area of ​​any two heating segments 131 are different. That is, in all heating segments 131 of a heating element 130, the heating power of each heating segment 131 is different. In this way, different areas of the heating surface corresponding to the heating element 130 can be heated differently, thereby meeting specific heating requirements and improving heating flexibility.

[0090] Furthermore, the heating element 130 also includes a spacer disposed between the two heating sections 131. The heating power of the spacer is lower than that of the adjacent heating section 131, so that a high-low temperature difference can be formed at both ends of the spacer, thereby improving the heating effect.

[0091] For example, when the heating element 130 heats the gas in the cooking cavity 111, the regions corresponding to different heating sections 131 will form a high-low temperature difference, which will cause the airflow to surge, further disturbing the airflow inside the cooking cavity 111, thereby improving the uniformity of heat inside the cooking cavity 111.

[0092] Specifically, for the same heating element 130, at least two heating segments 131 are connected in series, which simplifies the structure of the heating element 130 and improves the convenience of controlling the heating element 130.

[0093] It is worth noting that when there are multiple heating segments 131 connected in series, the heating power of the multiple heating segments 131 does not necessarily have to show a gradual trend of continuous increase or decrease from one end of the heating element 130 to the other, as long as it can complement the wind field. For example, when there are three heating segments 131, the heating power corresponding to the three series-connected heating segments 131 is P1, P2, and P3, and the relationship between the three can be P1 < P2, P3 < P2, that is, showing a trend of first increasing and then decreasing.

[0094] Furthermore, the heating element 130 includes a heating tube.

[0095] In this embodiment, the heating element 130 includes a heating tube, which comprises a tube body and a heating wire. The heating wire passes through the tube body, and the tube body protects the heating wire from damage. The heating wire can be divided into several segments of different lengths according to certain parameter requirements. The heating power of each segment is not exactly the same, enabling the use of a single heating source, such as a single heating element 130, to meet different heating needs at the same time, thus improving the flexibility of the heating element 130's configuration. It should be noted that the heating tube can be a metal tube, which generates heat to heat the air when energized. Alternatively, the heating tube can be a light radiation tube, which generates light radiation to heat food through thermal radiation.

[0096] It is worth noting that the heating element can be bent and deformed according to the needs of the cooking appliance 100, thus adapting to various installation requirements.

[0097] Furthermore, such as Figure 7 and Figure 8 As shown, the heating element includes a graphene tube 134.

[0098] In this embodiment, the heating wire in the heating element is made of graphene, which can improve the heating rate and heating efficiency of the heating element. When the cooking appliance 100 uses a graphene tube 134, the cooking appliance 100 can eliminate the preheating process, allowing the cooking temperature of the cooking appliance 100 to rise rapidly to the cooking temperature, shortening the cooking time and meeting the diverse cooking needs of users.

[0099] Specifically, the graphene sheet inside the graphene tube 134 can be divided into multiple heating sections 131 according to power requirements. The graphene sheets in different heating sections 131 have different cuts, and the cuts between two adjacent dotted lines are different, that is, the resistance is different. The power of different heating areas is different, so a high and low temperature difference can be formed.

[0100] By designing the graphene heating element with power segmentation, it is possible to meet the needs of a single heating element to heat different areas of the same surface at the same time. The structure is simple, the cost is low, and there is no need to set up a specific movement program, resulting in high reliability.

[0101] Additionally, it should be noted that, besides graphene, other materials can also achieve the effect of power segmentation.

[0102] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the housing 110 includes a surrounding plate 112, a top plate 115, and a bottom plate 116. A first vent 113 is provided on the surrounding plate 112, and an air supply assembly 120 is disposed on the outside of the cooking cavity 111 corresponding to the first vent 113. The top plate 115 is connected to the top of the surrounding plate 112. The bottom plate 116 is connected to the bottom of the surrounding plate 112, and the cooking cavity 111 is located between the surrounding plate 112, the top plate 115, and the bottom plate 116.

[0103] In this embodiment, the housing 110 includes a surrounding plate 112, a top plate 115, and a bottom plate 116 connected together. The top plate 115 is connected to the top of the surrounding plate 112, and the bottom plate 116 is connected to the bottom of the surrounding plate 112. The three are connected and enclose to form a cooking cavity 111. The cross-section of the surrounding plate 112 is approximately U-shaped. A first vent 113 is provided on the surrounding plate 112, which connects the cooking cavity 111 to the outside. An air supply assembly 120 is correspondingly provided at the first vent 113. When the air supply assembly 120 is working, it can form a pressure field, causing the airflow in the cooking cavity 111 to surge, and also allowing the airflow to circulate inside and outside the cooking cavity 111. The first vent 113 is an air inlet.

[0104] Furthermore, the air supply assembly 120 is located on the outside of the cooking cavity 111, meaning that the air supply assembly 120 does not occupy the space inside the cooking cavity 111, thereby providing a larger cooking cavity 111 to meet the user's cooking needs.

[0105] Furthermore, such as Figure 4 and Figure 5As shown, the heating element 130 includes a first heating element 132, which is connected to the top plate 115, and at least a portion of the first heating element 132 is located inside the cooking cavity 111.

[0106] In this embodiment, the heating element 130 includes a first heating element 132, which is connected to the top plate 115. That is, the first heating element 132 is located on the upper side of the cooking cavity 111. The first heating element 132 is mainly used to heat the air at the top of the cooking cavity 111. Since the air temperature at the top of the cooking cavity 111 is higher in the middle and lower on the sides, the heating elements 132 with higher heating power can be arranged closer to the sides, while the heating elements with lower heating power can be arranged closer to the center.

[0107] Furthermore, at least a portion of the first heating element 132 is located inside the cooking cavity 111, thereby enabling direct heating of the gas inside the cooking cavity 111 and reducing heat loss.

[0108] Furthermore, such as Figure 4 and Figure 5 As shown, the heating element 130 also includes a second heating element 133, which is located on the side of the base plate 116 away from the first heating element 132.

[0109] In this embodiment, the heating element 130 further includes a second heating element 133, which is located at the bottom of the cooking cavity 111. Specifically, the second heating element 133 is located on the outside of the cooking cavity 111, that is, on the lower side of the base plate 116. When food is being cooked in the cooking cavity 111, some food may fall or oil stains may easily drip down. If the second heating element 133 is located at the bottom of the cooking cavity 111 and inside the cooking cavity 111, food residue or oil stains may easily damage the second heating element 133, directly affecting its normal performance. By placing the second heating element 133 at the bottom of the base plate 116, the heating effect of the second heating element 133 on the airflow at the bottom of the cooking cavity 111 is not affected, while the service life of the second heating element 133 can be extended, and safety and hygiene during the cooking process can be ensured.

[0110] It should be noted that the first heating element 132 includes N heating segments 131, and at least two of the N heating segments 131 have different heating powers, where N is an integer greater than or equal to 2. Similarly, the second heating element 133 also includes N heating segments 131, and at least two of the N heating segments 131 have different heating powers, where N is an integer greater than or equal to 2. For both the first and second heating elements 132 and 133, the heating powers of at least two heating segments 131 within each heating element can be completely different or not completely the same. Furthermore, the trends in the heating power variations of multiple heating segments 131 in the first and second heating elements 132 and 133 can be the same or different.

[0111] Furthermore, such as Figure 4 and Figure 5 As shown, there are at least two first heating elements 132, and the at least two first heating elements 132 are arranged at intervals.

[0112] In this embodiment, when there are at least two first heating elements 132, the area that can be adjusted by at least two first heating elements 132 is larger, thereby quickly compensating for areas with less heat in the cooking cavity 111 and reducing heat transfer to areas with more heat in the cooking cavity 111, thus achieving rapid and uniform heat distribution in the cooking cavity 111.

[0113] Furthermore, such as Figure 4 and Figure 5 As shown, the number of second heating elements 133 is at least two, and the at least two second heating elements 133 are arranged at intervals.

[0114] In this embodiment, when there are at least two second heating elements 133, the area that can be adjusted by at least two second heating elements 133 is larger, thereby quickly compensating for areas with less heat in the cooking cavity 111 and reducing heat transfer to areas with more heat in the cooking cavity 111, thus achieving rapid and uniform heat distribution in the cooking cavity 111.

[0115] In this configuration, one first heating element 132 may extend along the left-right direction and be disposed on the housing 110, while multiple first heating elements 132 may be arranged side by side along the front-back direction. Alternatively, one first heating element 132 may extend along the front-back direction and be disposed on the housing 110, while multiple first heating elements 132 may be arranged side by side along the left-right direction. Alternatively, multiple first heating elements 132 may be arranged in a staggered manner, for example, one first heating element 132 may extend along the left-right direction and another first heating element 132 may extend along the front-back direction, with the two staggered at the top of the cooking cavity 111.

[0116] Similarly, the arrangement of the second heating element 133 can refer to the arrangement of the first heating element 132. The two can be arranged in the same direction or in different directions, depending on the actual needs.

[0117] Furthermore, such as Figure 5 As shown, the number of first heating elements 132 is greater than the number of second heating elements 133.

[0118] In this embodiment, the first heating element 132 is a top heat source and the second heating element 133 is a bottom heat source. When the food is placed in the cooking cavity 111, the food is usually placed on tableware. The first heating element 132, located above the food, can directly heat the food, while the second heating element 133, located below the food, will be blocked by the tableware. That is, the heating effect of the first heating element 132 on the food is more important than that of the second heating element 133. By making the number of first heating elements 132 greater than the number of second heating elements 133, the cooking effect of the food can be ensured while also saving costs to a certain extent.

[0119] Furthermore, such as Figure 2 As shown, the housing 110 also includes a second vent 114, which is disposed on the enclosure 112. The air supply assembly 120 is capable of circulating airflow between the first vent 113, the cooking cavity 111, and the second vent 114.

[0120] In this embodiment, the enclosure 112 includes a back panel, a first vent 113 is disposed on the back panel, a second vent 114 is also disposed on the back panel, and the air supply assembly 120 can be fixed on the back panel. When the air supply assembly 120 is working, the airflow can enter the cooking cavity 111 through the first vent 113. Under the action of the heating element 130, the hot airflow heats the food. A portion of the airflow will flow from the second vent 114 to the outside of the cooking cavity 111 and then be guided back into the cooking cavity 111 by the air supply assembly 120, thereby realizing the airflow circulation of the cooking appliance 100.

[0121] Furthermore, the enclosure 112 includes side panels connected to both sides of the back panel, and the first ventilation opening 113 can also be provided on either of the two side panels. The second ventilation opening 114 can also be provided on either of the two side panels.

[0122] It should be noted that the first ventilation opening 113 and the second ventilation opening 114 can be provided on the back panel or the side panel at the same time. One of the first ventilation opening 113 and the second ventilation opening 114 is provided on the side panel, and the other of the first ventilation opening 113 and the second ventilation opening 114 is provided on the back panel.

[0123] Furthermore, such as Figure 1 and Figure 4As shown, a portion of the base plate 116 is recessed in a direction away from the top plate 115.

[0124] In this embodiment, a portion of the base plate 116 is recessed downwards to form a guide groove. During the cooking process, food residue or oil stains will fall downwards. The guide groove is used to collect the residue, oil stains, etc., so that they gather in the middle of the base plate 116, making it convenient for the user to clean.

[0125] Furthermore, such as Figure 3 and Figure 4 As shown, the air supply assembly 120 includes a drive member 121 and a fan blade 122. The drive member 121 is disposed on the housing 110, and the fan blade 122 is connected to the drive member 121. The drive member 121 can drive the fan blade 122 to rotate, thereby disturbing the gas flow in the cooking cavity 111.

[0126] In this embodiment, the air supply assembly 120 includes a drive member 121 and a fan blade 122. The drive member 121 is detachably mounted on the housing 110 and serves as a power output component. The fan blade 122 is connected to the drive member 121, and the drive member 121 can drive the fan blade 122 to rotate. The rotation of the fan blade 122 creates a pressure field at the first vent 113, thereby disturbing the gas flow within the cooking cavity 111. The structure is simple and inexpensive.

[0127] Furthermore, the drive unit 121 includes a drive motor, the output shaft of which is connected to the fan blade 122.

[0128] In this embodiment, the drive unit 121 includes a drive motor, which includes a connected drive motor and an output shaft. The drive motor is fixed on the housing 110, and the output shaft is connected to the fan blade 122. The output shaft and the fan blade 122 can rotate synchronously relative to the drive motor.

[0129] Furthermore, such as Figure 4 and Figure 5 As shown, the cooking appliance 100 also includes a heating element 140, which is disposed on the housing 110 and located between the air supply assembly 120 and the housing 110.

[0130] In this embodiment, the cooking appliance 100 further includes a heating element 140, which is disposed on the housing 110 and located on one side of the air supply assembly 120. The heating element 140 can heat the gas about to enter the cooking chamber 111, so that the airflow blown into the cooking chamber 111 by the air supply assembly 120 through the first vent 113 is a hot airflow. The air supply assembly 120 and the heating element 140 together constitute a hot air assembly, thereby further improving the heating efficiency of the cooking appliance 100. That is, the cooking appliance 100 not only has a first heating element 132 and a second heating element 133 located in the vertical direction, but also a heating element 140 located on the rear side of the cooking chamber 111. The first heating element 132, the second heating element 133, and the heating element 140 can provide heat sources for the food from three directions. When the heating element 140 and the air supply assembly 120 work together to supply hot air into the cooking cavity 111, the airflow distribution within the cooking cavity 111 is uneven. Areas easily reached by the airflow are areas of concentrated heat, while areas difficult to reach are areas of insufficient heat. The heating element 130 can be configured to adjust the concentrated heat areas and areas of insufficient heat in a zoned manner. The heating section 131 corresponding to the concentrated heat areas has a lower power, while the heating section 131 corresponding to the insufficient heat areas has a higher power, thereby making the heat distribution area inside the entire cooking cavity 111 more uniform, which can improve the cooking effect and cooking efficiency.

[0131] Furthermore, such as Figure 4 and Figure 5 As shown, the heating element 140 includes a heating tube arranged around the air supply assembly 120.

[0132] In this embodiment, the heating element 140 includes a heating tube, which is bent to form an annular coil. The central area of ​​the annular coil has a receiving area, and a part of the air supply assembly 120 can be located in the receiving area. This makes the arrangement of the heating element 140 and the air supply assembly 120 more rational and centralized, and can shorten the space occupied by the two in the front-to-back direction, so that the overall size of the cooking appliance 100 is reduced, which is in line with the trend of product miniaturization.

[0133] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cooking appliance 100 also includes a storage piece 150, which is detachably disposed on the housing 110 and located inside the cooking cavity 111. The storage piece 150 is used to place food ingredients.

[0134] In this embodiment, the cooking appliance 100 also includes a placement component 150, which is detachably disposed on the housing 110 and located inside the cooking cavity 111. Food ingredients can be placed on the placement component 150, and the user can retrieve the food ingredients through the placement component 150.

[0135] When the cooking appliance 100 is an oven, the storage item 150 can be a baking tray, a baking rack, etc.

[0136] When the cooking appliance 100 is an air fryer, the storage container 150 can be a frying basket or the like.

[0137] Furthermore, the cooking appliance 100 includes an oven.

[0138] Specifically, such as Figures 1 to 5 As shown, the cooking appliance 100 provided in this application includes a housing 110, an air supply assembly 120, and a heating element 130. The housing 110 has a cooking cavity 111 for accommodating food. The air supply assembly 120 is disposed on the housing 110, and the heating element 130 is disposed on the housing 110. The housing 110 not only forms a space for accommodating food but also serves as a mounting and fixing point for the air supply assembly 120 and the heating element 130. The heating element 130 heats the airflow within the cooking cavity 111, thereby forming a hot airflow. The air supply assembly 120 can agitate the airflow within the cooking cavity 111, making the hot airflow more evenly distributed within the cooking cavity 111 and improving the heating uniformity of the cooking appliance 100.

[0139] The heating element 130 includes at least two heating sections 131, and at least two of the heating sections 131 have different heating powers. That is, the heating powers of the multiple heating sections 131 are not completely the same. The heating sections 131 with different heating powers can be set according to the distribution of the airflow in the cooking cavity 111. In areas where the heat is more concentrated, heating sections 131 with lower heating powers can be set, and in areas where the heat is more dispersed, heating sections 131 with higher heating powers can be set. This avoids the food in areas with concentrated heat being heated to an excessively high temperature and burning, and avoids the food in areas with dispersed heat not receiving enough heat and failing to be cooked.

[0140] In this application, by setting heating sections 131 with different heating powers in the cooking appliance, the heat field generated by the heating element 130 and the air field formed by the air supply component 120 can complement each other, thereby improving the uniformity of heat distribution in the entire cooking cavity 111, increasing the heating speed, and improving the cooking effect.

[0141] Specifically, for local areas where the wind is difficult to reach and the heat is too low, the heating power of the corresponding heating section 131 can be increased. Conversely, for local areas where the wind is easy to reach and the heat is too high, the heating power of the corresponding heating section 131 can be decreased. In this way, the heat field formed by the heating element 130 and the wind field formed by the air supply component 120 can complement each other, achieving a uniform distribution of heat in the cooking cavity 111, improving the cooking effect of the cooking appliance 100, and accelerating the cooking efficiency.

[0142] Furthermore, such as Figure 6 , Figure 7 and Figure 8 As shown, for the heating efficiency of heating section 131, the heating power calculation formula is P = U. 2 / R, where P represents heating power, U represents voltage, and R represents resistance. According to the formula for calculating heating power, under the same voltage, changing the resistance will change the heating power. The formula for calculating resistance is R = ρL / S, where R represents resistance, ρ represents resistivity, L represents the length of the resistor, and S represents the cross-sectional area of ​​the resistor. According to the formula for calculating resistance, changing at least one of the resistivity, length, or cross-sectional area of ​​a resistor will change its resistance.

[0143] Therefore, by setting at least two heating sections 131 with different resistivity and / or length and / or cross-sectional area, this application ensures that the heating power of the heating sections 131 is not completely the same. When the heating element 130 heats any surface, such as the surface of a cookware, baking tray, or other device, the heating conditions of that surface are different. While ensuring a simple structure and not increasing costs, it can meet specific heating requirements and improve the flexibility of heating.

[0144] Specifically, for the same heating element 130, at least two heating segments 131 are connected in series, which simplifies the structure of the heating element 130 and improves the convenience of controlling the heating element 130.

[0145] Furthermore, the heating element 130 includes a heating tube.

[0146] In this embodiment, the heating element 130 includes a heating tube, which comprises a tube body and a heating wire. The heating wire passes through the tube body, and the tube body protects the heating wire from damage. The heating wire can be divided into several segments of different lengths according to certain parameter requirements. The heating power of each segment is not exactly the same, which enables the use of a single heating source, such as a single heating element 130, to meet different heating needs at the same time, thus improving the flexibility of the heating element 130 setting.

[0147] It is worth noting that the heating element can be bent and deformed according to the needs of the cooking appliance 100, thus adapting to various installation requirements.

[0148] Furthermore, such as Figure 7 and Figure 8 As shown, the heating wire in the heating element is made of graphene, which can improve the heating speed and heating efficiency of the heating element. When the cooking appliance 100 uses the graphene tube 134, the cooking appliance 100 can eliminate the preheating process, allowing the cooking temperature of the cooking appliance 100 to rise rapidly to the cooking temperature, shortening the cooking time and meeting the diverse cooking needs of users.

[0149] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the housing 110 includes a surrounding plate 112, a top plate 115, and a bottom plate 116 connected together. The top plate 115 is connected to the top of the surrounding plate 112, and the bottom plate 116 is connected to the bottom of the surrounding plate 112. The three are connected and enclose to form a cooking cavity 111. The cross-section of the surrounding plate 112 is approximately U-shaped. A first vent 113 is provided on the surrounding plate 112, which connects the cooking cavity 111 to the outside. An air supply assembly 120 is correspondingly provided at the first vent 113. When the air supply assembly 120 is working, it can create a pressure field, causing the airflow in the cooking cavity 111 to surge, and also allowing the airflow to circulate inside and outside the cooking cavity 111. The first vent 113 is an air inlet.

[0150] Furthermore, the air supply assembly 120 is located on the outside of the cooking cavity 111, meaning that the air supply assembly 120 does not occupy the space inside the cooking cavity 111, thereby providing a larger cooking cavity 111 to meet the user's cooking needs.

[0151] Furthermore, such as Figure 4 and Figure 5 As shown, the heating element 130 includes a first heating element 132, which is connected to the top plate 115. That is, the first heating element 132 is located on the upper side of the cooking cavity 111. The first heating element 132 is mainly used to heat the air at the top of the cooking cavity 111. Since the air temperature at the top of the cooking cavity 111 is higher in the middle and lower on the sides, the heating elements 132 with higher heating power can be arranged closer to the sides, while the heating elements with lower heating power can be arranged closer to the middle.

[0152] Furthermore, at least a portion of the first heating element 132 is located inside the cooking cavity 111, thereby enabling direct heating of the gas inside the cooking cavity 111 and reducing heat loss.

[0153] Furthermore, such as Figure 4and Figure 5 As shown, the heating element 130 also includes a second heating element 133, which is located at the bottom of the cooking cavity 111. Specifically, the second heating element 133 is located on the outside of the cooking cavity 111, that is, on the lower side of the base plate 116. When food is being cooked in the cooking cavity 111, some food may fall or oil stains may easily drip down. If the second heating element 133 is located at the bottom of the cooking cavity 111 and inside the cooking cavity 111, food residue or oil stains may easily damage the second heating element 133, directly affecting its normal performance. By placing the second heating element 133 at the bottom of the base plate 116, the heating effect of the second heating element 133 on the airflow at the bottom of the cooking cavity 111 is not affected, while the service life of the second heating element 133 is extended, and safety and hygiene during the cooking process are ensured.

[0154] Furthermore, such as Figure 2 As shown, the enclosure 112 includes a back panel, a first vent 113 is provided on the back panel, a second vent 114 is also provided on the back panel, and the air supply assembly 120 can be fixed on the back panel. When the air supply assembly 120 is working, the airflow can enter the cooking cavity 111 through the first vent 113. Under the action of the heating element 130, the hot airflow heats the food. A portion of the airflow will flow from the second vent 114 to the outside of the cooking cavity 111 and then be guided back into the cooking cavity 111 by the air supply assembly 120, thereby realizing the airflow circulation of the cooking appliance 100.

[0155] Furthermore, such as Figure 1 and Figure 4 As shown, a portion of the base plate 116 is recessed downwards to form a guide groove. During the cooking process, food residue or oil stains will fall downwards. The guide groove is used to collect the residue, oil stains, etc., and gather them in the middle of the base plate 116, making it convenient for the user to clean.

[0156] Furthermore, such as Figure 3 and Figure 4 As shown, the air supply assembly 120 includes a drive component 121 and a fan blade 122. The drive component 121 is detachably mounted on the housing 110 and serves as a power output component. The fan blade 122 is connected to the drive component 121, which drives the fan blade 122 to rotate. The rotation of the fan blade 122 creates a pressure field at the first vent 113, thereby disturbing the gas flow within the cooking cavity 111. The structure is simple and inexpensive.

[0157] Furthermore, such as Figure 4 and Figure 5As shown, the cooking appliance 100 also includes a heating element 140, which is mounted on the housing 110 and located on one side of the air supply assembly 120. The heating element 140 heats the gas about to enter the cooking chamber 111, so that the airflow blown into the cooking chamber 111 by the air supply assembly 120 through the first vent 113 is hot air. The air supply assembly 120 and the heating element 140 together constitute a hot air assembly, thereby further improving the heating efficiency of the cooking appliance 100. That is, the cooking appliance 100 not only has a first heating element 132 and a second heating element 133 located in the vertical direction, but also a heating element 140 located on the rear side of the cooking chamber 111. The first heating element 132, the second heating element 133, and the heating element 140 can provide heat sources for the food from three directions. When the heating element 140 and the air supply assembly 120 work together to supply hot air into the cooking cavity 111, the airflow distribution within the cooking cavity 111 is uneven. Areas easily reached by the airflow are areas of concentrated heat, while areas difficult to reach are areas of insufficient heat. The heating element 130 can be configured to adjust the concentrated heat areas and areas of insufficient heat in a zoned manner. The heating section 131 corresponding to the concentrated heat areas has a lower power, while the heating section 131 corresponding to the insufficient heat areas has a higher power, thereby making the heat distribution area inside the entire cooking cavity 111 more uniform, which can improve the cooking effect and cooking efficiency.

[0158] Furthermore, such as Figure 4 and Figure 5 As shown, the heating element 140 includes a heating tube, which is bent to form an annular coil. The central area of ​​the annular coil has a receiving area, and a part of the air supply assembly 120 can be located in this receiving area. This allows for a more rational and centralized arrangement of the heating element 140 and the air supply assembly 120, reducing the space occupied by them in the front-to-back direction and making the overall size of the cooking appliance 100 smaller, thus adapting to the trend of product miniaturization.
