Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, and in particular to an air fryer with good cooking effect. Background Technology

[0002] With societal development, the oil-free cooking method of air fryers is becoming increasingly popular. In traditional air fryers, the frying system is usually located at the top of the cooking chamber, heating the food in the basket through top-blowing air. While this method improves heating efficiency, the circulating hot air is blown directly into the basket from top to bottom, which can easily cause food to burn and result in uneven heating, poor cooking quality, and a poor user experience. To meet user needs, a new type of air fryer with side-blowing air has emerged on the market. This type features a hot air circulation system on the side of the cooking chamber and a heating element at the top. By guiding the circulating airflow generated by the hot air circulation system to the top of the cooking chamber, heating it through the heating element, and then flowing into the basket, this method avoids the direct blowing of hot air into the cooking chamber. However, this airflow often tends to concentrate in specific areas, leading to uneven heating of the food in different areas of the basket during cooking, resulting in cooking inconsistencies and a poor cooking effect, further contributing to a poor user experience. Utility Model Content

[0003] This application provides an air fryer with good cooking results to solve the technical problems of existing air fryers, such as inconsistent cooking areas, poor cooking results, and unsatisfactory user experience.

[0004] To solve the above-mentioned technical problems, this utility model provides an air fryer with good cooking effect, including a body, a cooking cavity disposed in the body and a concave cavity disposed outside the cooking cavity. A heat circulation fan is provided in the concave cavity. An air duct plate is provided at the top of the cooking cavity. The air duct plate is adapted to be concave upward to form a downward-opening air guide cavity. An air inlet is provided on one side of the air guide cavity. The air inlet is connected to the concave cavity. A downward-protruding guide protrusion is provided in the middle of the air guide cavity. A frying basket with an open top is provided in the cooking cavity. The guide protrusion is located directly above the open top of the frying basket. The width of the guide protrusion is designed to gradually increase from the end near the air inlet to the end away from the air inlet in at least a part of the area. By providing a downward-opening air guide cavity at the top of the cooking chamber, and a guide protrusion in the middle of the air guide cavity corresponding to the opening at the top of the frying basket, the circulating heat flow generated by the hot air circulation fan can be diverted and more evenly introduced into the frying basket, thereby heating the food in the frying basket and effectively improving the cooking effect. At the same time, the guide protrusion is designed to gradually increase in size from the end near the air inlet to the end away from the air inlet, which allows the guide protrusion to better divert the circulating heat flow entering the air guide cavity through the air inlet. This not only reduces the resistance encountered by the circulating heat flow when it is diverted, thereby improving the heat flow circulation efficiency in the cooking chamber and thus improving the cooking efficiency, but also reduces the noise of the air fryer during operation, effectively improving the user experience.

[0005] In an optional embodiment, the end of the guide protrusion near the air inlet is adapted to be biased towards the rotation direction of the heat circulation fan. This arrangement allows the guide protrusion to better divert the circulating hot air entering the air guide cavity through the air inlet, reducing the problem of uneven left and right air diversion causing differences in the cooking area and effectively improving the cooking effect.

[0006] In an optional embodiment, the sidewall of the air guide protrusion is adapted to be an arc-shaped air guide structure extending inward from the end near the air duct plate to the end away from the air duct plate. By setting the sidewall of the air guide protrusion to an arc-shaped air guide structure extending inward from the end near the air duct plate to the end away from the air duct plate, not only can the air guide protrusion better guide the circulating heat flow in the air guide cavity into the frying basket, thereby improving the cooking efficiency of the air fryer, but it can also prevent the air guide protrusion from causing regional accumulation when guiding the circulating heat flow into the frying basket, effectively ensuring the cooking effect of the air fryer.

[0007] In an optional embodiment, a guide vane is provided near the air inlet in the air guide cavity. The guide vane is adapted to extend in an arc shape towards the center of the air guide cavity, and the bending direction of the guide vane is opposite to the rotation direction of the heat circulation fan. By providing the guide vane near the air inlet in the air guide cavity and setting the bending direction of the guide vane to be opposite to the rotation direction of the heat circulation fan, not only can the circulating heat flow entering the air guide cavity through the air inlet be diverted, but the diverted circulating heat flow can also be guided to both sides of the air guide cavity to cooperate with the guide protrusion, thereby introducing the circulating heat flow into the frying basket more evenly and effectively improving the cooking effect of the food in the frying basket.

[0008] In an optional embodiment, the air guide vane is adapted to be positioned in the air guide cavity on one side biased towards the rotation direction of the hot air circulation fan. This arrangement reduces the impact of air pressure differences in the airflow generated by the hot air circulation fan on the air guide vane's diversion and guidance, resulting in a more uniform distribution of airflow diverted into the air guide cavity by the air guide vane. Consequently, the airflow guided into the frying basket by the air guide cavity and the guide protrusions is more evenly distributed, effectively improving the cooking effect.

[0009] In one optional embodiment, the air guide plate has multiple bendable sections, and the air duct plate has multiple fixing holes through which the bendable sections can pass. The bendable sections are adapted to pass through the fixing holes from the bottom of the air duct plate and abut against the top of the air duct plate after being bent. By providing multiple bendable sections on the air guide plate, the air fryer can fix the air guide plate to the air duct plate by bending the bendable sections. Simultaneously, by providing multiple bendable sections on the air guide plate, not only can the connection stability between the air guide plate and the air duct plate be ensured, but the installation, disassembly, and replacement of the air guide plate are also facilitated, effectively improving the ease of use of the air guide plate.

[0010] In an optional embodiment, the air guide vane has an inwardly recessed notch at one end near the air inlet. This notch is adapted to be an arc-shaped concave structure extending inwardly from the end of the air guide vane near the air duct plate towards the end away from the air duct plate. By providing the inwardly recessed notch at the end of the air guide vane near the air inlet, the circulating hot flow entering the air guide cavity through the air inlet can be better diverted. This not only reduces the resistance encountered by the circulating hot flow during diversion, thereby improving the heat flow circulation efficiency within the cooking cavity and thus improving cooking efficiency, but also reduces the noise of the air fryer during operation, effectively enhancing the user experience.

[0011] In one optional embodiment, the bottom wall of the air inlet is arc-shaped, and the projections of the heat circulation fan and the air inlet on the rotation axis of the heat circulation fan at least partially overlap. When the projections of the heat circulation fan and the air inlet on the rotation axis of the heat circulation fan overlap, the air inlet faces the outside of the heat circulation fan. Therefore, by setting the bottom wall of the air inlet to be arc-shaped and setting the projections of the heat circulation fan and the air inlet on the rotation axis of the heat circulation fan to overlap, the air inlet can better guide the circulating heat flow generated by the heat circulation fan, thereby increasing the rate at which the circulating heat flow enters the air guide cavity and the cooking cavity through the air inlet, thus improving the heat flow circulation efficiency in the air guide cavity and the cooking cavity, and consequently improving the cooking efficiency of the air fryer.

[0012] In an optional embodiment, the sidewall of the air guide cavity opposite to the air inlet protrudes in the direction of the guide protrusion to form a guide portion. By providing the guide portion protruding in the direction of the guide protrusion on the side of the air guide cavity opposite to the air inlet, the airflow on both sides of the air guide cavity can be guided towards the center of the air guide cavity, and then downwards into the frying basket via the guide protrusion. This avoids the airflow on both sides of the air guide cavity from colliding and forming turbulence, thereby affecting the heat circulation speed in the cooking cavity and effectively improving the cooking efficiency of the air fryer.

[0013] In an optional embodiment, a heating assembly is provided within the air guide cavity. The heating assembly includes a heating element adapted to surround the air guide protrusion. By placing the heating element within the air guide cavity and surrounding the air guide protrusion, better heating of the airflow entering the air guide cavity can be achieved, avoiding regional temperature differences that could lead to variations in the cooking area and effectively ensuring the cooking effect of the air fryer.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] This application, by providing a downward-opening air guide cavity at the top of the cooking cavity and a guide protrusion in the middle of the air guide cavity corresponding to the opening at the top of the frying basket, can achieve a more even distribution of the circulating heat flow generated by the hot air circulation fan into the frying basket, thereby heating the food in the frying basket and effectively improving the cooking effect. At the same time, by designing the guide protrusion to gradually increase in size from the end near the air inlet to the end away from the air inlet, the guide protrusion can better distribute the circulating heat flow entering the air guide cavity through the air inlet. This not only reduces the resistance encountered by the circulating heat flow when it is distributed, thereby improving the heat flow circulation efficiency in the cooking cavity and thus improving the cooking efficiency, but also reduces the noise of the air fryer during operation, effectively improving the user experience.

The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0027] Appendix Figure 1 To be continued Figure 5 The diagram shown is a schematic diagram of the first embodiment of an air fryer with good cooking effect provided by this utility model. The air fryer includes a body 10 and a cooking chamber 11 with an open front side inside the body 10. A concave cavity 12 communicating with the cooking chamber 11 is provided outside the cooking chamber 11. A hot air circulation fan 20 for generating circulating airflow is provided in the concave cavity 12. A heating component 30 is provided on the airflow circulation path of the hot air circulation fan 20. The heating component 30 is adapted to heat the circulating airflow generated by the hot air circulation fan 20 to form a circulating heat flow, thereby heating the food in the cooking chamber 11.

[0028] like Figures 2 to 5 As shown, in an optional embodiment, the cooking cavity 11 is provided with an air duct plate 13 at the top. The air duct plate 13 is adapted to be recessed upward to form a downward-opening air guide cavity 131. An air inlet 132 is provided on one side of the air guide cavity 131, and the air inlet 132 is adapted to communicate with the concave cavity 12. A downward-protruding guide protrusion 133 is provided in the middle of the air guide cavity 131. The cooking cavity 11 is provided with a frying basket 40 that can be pulled out through the front opening and has a top opening. The guide protrusion 133 is adapted to position... Directly above the top opening of the frying basket 40, a hot air hole 41 communicating with the cooking chamber 11 is provided on the frying basket 40. A return air inlet 111 corresponding to the hot air circulation fan 20 is provided on the side wall of the cooking chamber 11. The circulating airflow generated by the hot air circulation fan 20 is adapted to enter the air guide cavity 131 through the air inlet 132, and then be guided downwards by the guide protrusion 133 into the frying basket 40, and then return to the concave cavity 12 via the hot air hole 41 and the return air inlet 111. By providing a downward-opening air guide cavity 131 at the top of the cooking chamber 11, and providing a guide protrusion 133 corresponding to the top opening of the frying basket 40 in the middle of the air guide cavity 131, the circulating heat flow generated by the hot air circulation fan 20 can be diverted and more evenly introduced into the frying basket 40, thereby heating the food in the frying basket 40 and effectively improving the cooking effect.

[0029] like Figures 3 to 5As shown, the width of the guide protrusion 133 preferably gradually increases from the end near the air inlet 132 to the end away from the air inlet 132. By designing the width of the guide protrusion 133 to gradually increase from the end near the air inlet 132 to the end away from the air inlet 132, the guide protrusion 133 can better divert the circulating hot flow entering the air guide cavity 131 through the air inlet 132. This not only reduces the resistance encountered by the circulating hot flow when it is diverted, thereby improving the heat flow circulation efficiency of the circulating hot flow in the cooking cavity 11 and thus improving cooking efficiency, but also reduces the noise of the air fryer during operation, effectively improving the user experience.

[0030] like Figures 3 to 5 As shown, the end of the guide protrusion 133 near the air inlet 132 is adapted to be biased towards the rotation direction of the heat circulation fan 20. When the heat circulation fan 20 rotates, it is adapted to generate a spiral airflow. After entering the air inlet 131, the spiral airflow will form a high-pressure zone in the same direction as the rotation of the heat circulation fan 20 and a low-pressure zone in the opposite direction to the rotation of the heat circulation fan 20. Therefore, by biasing the end of the guide protrusion 133 near the air inlet 132 towards the rotation direction of the heat circulation fan 20, the guide protrusion 133 can better divert the circulating hot air entering the air guide cavity through the air inlet, reduce the problem of uneven diversion between the left and right sides causing differences in the cooking area, and effectively improve the cooking effect.

[0031] like Figure 2 and Figure 5 As shown, in an optional embodiment, the sidewall of the air guide protrusion 133 is adapted to be an arc-shaped air guide structure extending inward from one end near the air duct plate 13 to the end away from the air duct plate 13. By setting the sidewall of the air guide protrusion 133 to an arc-shaped air guide structure extending inward from one end near the air duct plate 13 to the end away from the air duct plate 13, not only can the air guide protrusion 133 better guide the circulating heat flow in the air guide cavity 131 into the frying basket 40, thereby improving the cooking efficiency of the air fryer, but it can also avoid the situation of regional accumulation of the air guide protrusion 133 when guiding the circulating heat flow into the frying basket 40, effectively ensuring the cooking effect of the air fryer.

[0032] like Figure 3 and Figure 5As shown, in an optional embodiment, a guide vane 14 is provided in the air guide cavity 131 near the air inlet 132. The guide vane 14 is adapted to extend in an arc shape towards the center of the air guide cavity 131, and the bending direction of the guide vane 14 is opposite to the rotation direction of the heat circulation fan 20. By providing the guide vane 14 in the air guide cavity 131 near the air inlet 132 and setting the bending direction of the guide vane 14 to be opposite to the rotation direction of the heat circulation fan 20, not only can the circulating hot flow entering the air guide cavity 131 through the air inlet 132 be diverted, but the diverted circulating hot flow can also be guided to both sides of the air guide cavity 131 to cooperate with the guide protrusion 133 to introduce the circulating hot flow into the frying basket 40 more evenly, effectively improving the cooking effect of the food in the frying basket 40.

[0033] like Figure 3 and Figure 5 As shown, in an optional embodiment, the air guide vane 14 is adapted to be disposed in the air guide cavity 131 on one side biased towards the rotation direction of the heat circulation fan 20. When the heat circulation fan 20 rotates, it is adapted to generate a spiral airflow. After entering the air inlet 131, the spiral airflow forms a high-pressure zone in the same direction as the rotation of the heat circulation fan 20 and a low-pressure zone in the opposite direction to the rotation of the heat circulation fan 20. The airflow volume in the high-pressure zone is larger, and the airflow volume in the low-pressure zone is smaller. Therefore, by distributing the air guide vane 14 in the air guide cavity 131 on one side biased towards the rotation direction of the heat circulation fan 20, the airflow in the high-pressure zone can be diverted and introduced into the low-pressure zone, so that the airflow diverted and introduced into the air guide cavity 131 by the air guide vane 14 is more evenly distributed. This makes the airflow guided into the frying basket 40 by the air guide cavity 131 and the guide protrusion 133 more evenly distributed, which can effectively improve the cooking effect.

[0034] like Figure 4 and Figure 5 As shown, in an optional embodiment, the air guide plate 14 is provided with a plurality of bendable bending portions 141, and the air duct plate 13 is provided with a plurality of fixing holes 134 through which the bending portions 141 can pass. The bending portions 141 are adapted to pass through the fixing holes 141 from the bottom of the air duct plate 13 and abut against the top of the air duct plate 13 after being bent. By providing a plurality of bendable bending portions 141 on the air guide plate 14, the air fryer can fix the air guide plate 14 to the air duct plate 13 by bending the bending portions 141. At the same time, by providing a plurality of bendable bending portions 141 on the air guide plate 14, not only can the connection stability between the air guide plate 14 and the air duct plate 13 be ensured, but the installation, disassembly and replacement of the air guide plate 14 can also be facilitated, which can effectively improve the ease of use of the air guide plate 14.

[0035] like Figure 4 and Figure 5 As shown, in an optional embodiment, the air guide vane 14 has an inwardly recessed notch 142 at one end near the air inlet 132. The notch 142 is adapted to be an arc-shaped concave structure extending inwardly from the end of the air guide vane 14 near the air duct plate 13 toward the end away from the air duct plate 13. By providing the inwardly recessed notch 142 at the end of the air guide vane 14 near the air inlet 132, the circulating hot flow entering the air guide cavity 131 through the air inlet 132 can be better diverted. This not only reduces the resistance encountered by the circulating hot flow when it is diverted, thereby improving the heat flow circulation efficiency of the circulating hot flow in the cooking cavity 11 and thus improving cooking efficiency, but also reduces the noise of the air fryer during operation, effectively improving the user experience.

[0036] like Figure 2 As shown, in an optional embodiment, the bottom wall of the air inlet 132 is arc-shaped, and the projections of the heat circulation fan 20 and the air inlet 132 on the rotation axis of the heat circulation fan 20 at least partially overlap. When the projections of the heat circulation fan 20 and the air inlet 132 on the rotation axis of the heat circulation fan 20 overlap, the air inlet 132 faces the outside of the heat circulation fan 20. Therefore, by setting the bottom wall of the air inlet 132 to be arc-shaped and setting the projections of the heat circulation fan 20 and the air inlet 132 on the rotation axis of the heat circulation fan 20 to overlap, the air inlet 132 can better guide the circulating heat flow generated by the heat circulation fan 20, thereby increasing the rate at which the circulating heat flow enters the air guide cavity 131 and the cooking cavity 11 through the air inlet 132, thus improving the heat flow circulation efficiency in the air guide cavity 131 and the cooking cavity 11, and further improving the cooking efficiency of the air fryer.

[0037] like Figures 3 to 5 As shown, in an optional embodiment, the sidewall of the air guide cavity 131 opposite to the air inlet 132 is adapted to protrude towards the guide protrusion 133 to form a guide portion 135. By providing the guide portion 135 protruding towards the guide protrusion 133 on the side of the air guide cavity 131 opposite to the air inlet 132, the airflow on both sides of the air guide cavity 131 can be guided towards the center of the air guide cavity 131, and then downwards into the frying basket 40 via the guide protrusion 133, so as to avoid the airflow on both sides of the air guide cavity 131 colliding and forming turbulence, thereby affecting the heat flow circulation speed in the cooking cavity 11 and effectively improving the cooking efficiency of the air fryer.

[0038] like Figure 2 and Figure 3As shown, in an optional embodiment, the heating assembly 30 is provided within the air guide cavity 131. The heating assembly 30 includes a heating element 31, which is adapted to surround the air guide protrusion 133. By placing the heating element 31 within the air guide cavity 131 and surrounding the air guide protrusion 133, better heating of the airflow entering the air guide cavity 131 can be achieved, avoiding regional temperature differences and thus preventing cooking zone differences, effectively ensuring the cooking effect of the air fryer.

[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. The purpose of this utility model has been fully and effectively achieved. Those skilled in the art should understand that the embodiments of this utility model described above and shown in the accompanying drawings are merely examples and do not limit the scope of this utility model. For those skilled in the art, several simple deductions or substitutions can be made without departing from this utility model, and all such modifications or substitutions should be considered to fall within the scope of patent protection defined by the claims submitted herein.
