Description

Technical Field

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

[0002] As people's living standards improve, the oil-free cooking method of air fryers is becoming increasingly popular. However, in most existing air fryers, there is a gap between the folded edge of the frying basket and the contact point between the basket and the lower core. This gap allows water vapor generated during air frying to easily flow through the gap to the bottom of the cooking chamber under air pressure, resulting in condensation. Similarly, during steam cooking, steam also easily flows through this gap to the bottom of the cooking chamber, causing condensation and overflowing outside the chamber, thus affecting the cooking results and leading to a poor user experience. Utility Model Content

[0003] This application provides an air fryer with good sealing performance to solve the technical problem that in existing air fryers, water vapor easily flows to the bottom of the cooking cavity through the gap between the frying basket and the lower core under the action of wind pressure, thereby forming condensation at the bottom of the cooking cavity and causing a poor user experience.

[0004] To address the aforementioned technical problems, this utility model provides an air fryer with excellent sealing performance, comprising a body and a cooking chamber with an open side opening within the body. A detachable top-opening frying basket is provided within the cooking chamber through the side opening. The top opening of the frying basket has an outwardly folded flange around its perimeter. A step corresponding to the flange is provided on the side wall of the cooking chamber, and a first sealing element is provided on the step. When the frying basket is installed in the cooking chamber, the lower side of the flange is adapted to seal with the first sealing element. By providing the step corresponding to the flange on the side wall of the cooking chamber, and providing the first sealing element on the step to seal with the lower side of the flange, a sealed connection between the frying basket and the side wall of the cooking chamber can be achieved. This effectively prevents water vapor in the cooking chamber from flowing through the gap between the frying basket and the side wall of the cooking chamber to the bottom of the cooking chamber, thus preventing condensation at the bottom of the cooking chamber and significantly improving the user experience.

[0005] In an optional embodiment, a lower core constituting at least a portion of the cooking cavity is provided at the bottom of the cooking cavity, and an upper core is provided above the lower core. The lower core has a top opening, and a first sealing member is provided around the periphery of the top opening. The lower core is adapted to abut against the upper core through the first sealing member. By clamping the first sealing member between the upper core and the lower core, a sealed connection between the upper core and the lower core can be achieved. This not only prevents the circulating heat flow and / or water vapor in the cooking cavity from flowing out of the cooking cavity through the connection gap between the upper core and the lower core, thereby preventing it from affecting the normal operation of the electrical components outside the cooking cavity, but also effectively ensures the performance stability and safety of the air fryer.

[0006] In an optional embodiment, the lower movement has a recessed mounting groove around the top opening, and the lower side of the first seal has a mounting portion that matches the mounting groove, the mounting portion being at least partially confined within the mounting groove. The mounting groove is adapted to position and / or limit the installation of the first seal. Positioning and / or limiting the first seal through the mounting groove not only effectively reduces the installation difficulty of the first seal, but also reduces the possibility of poor sealing caused by the compression deformation or displacement of the upper and lower movements, effectively ensuring the sealing stability when the upper and lower movements are connected.

[0007] In one optional embodiment, an air duct plate is provided at the top of the cooking cavity, and an upper core is provided above the air duct plate. A second sealing element matching the periphery of the air duct plate is sandwiched between the air duct plate and the upper core. The air duct plate is adapted to be sealed with the upper core through the second sealing element. By sandwiching the second sealing element matching the periphery of the air duct plate between the air duct plate and the upper core, a sealed connection between the upper core and the air duct plate can be achieved, preventing the circulating heat flow and / or water vapor in the cooking cavity from flowing out of the cooking cavity through the connection gap between the upper core and the air duct plate, thereby preventing it from affecting the normal operation of the electrical components outside the cooking cavity and effectively ensuring the performance stability and safety of the air fryer.

[0008] In an optional embodiment, the upper core has an upwardly recessed sealing groove on the side facing the air duct plate, and the second sealing element is at least partially confined within the sealing groove. The sealing groove is adapted to position and / or limit the installation of the second sealing element. Positioning and / or limiting the second sealing element through the sealing groove can not only effectively reduce the installation difficulty of the second sealing element, but also reduce the possibility of poor sealing caused by the compression deformation or displacement of the second sealing element by the upper core and the air duct plate, effectively ensuring the sealing stability when the upper core and the air duct plate are connected.

[0009] In an optional embodiment, the first and second seals are adapted to be made of an elastic, high-temperature resistant material. By using an elastic, high-temperature resistant material to manufacture the first and second seals, the impact of the high temperature inside the cooking cavity on the first and second seals can be reduced, effectively ensuring the sealing stability and sealing effect of the first and second seals.

[0010] In an optional embodiment, the top of the cooking cavity is provided with a hot air cavity with an opening facing downward, formed by the upward indentation of the air duct plate. The hot air cavity is provided with a hot air circulation system, and the opening of the hot air cavity is adapted to correspond to the top opening of the frying basket. By aligning the opening of the hot air chamber with the top opening of the frying basket, the circulating heat generated by the hot air circulation system can circulate better between the frying basket and the hot air chamber, effectively improving the cooking efficiency and effect of the food in the frying basket. Simultaneously, aligning the opening of the hot air chamber with the top opening of the frying basket also reduces the outflow of water vapor to the outside of the frying basket, thus reducing condensation at the bottom of the cooking cavity and preventing a poor user experience. Furthermore, aligning the opening of the hot air chamber with the top opening of the frying basket also reduces the outflow of circulating heat and / or water vapor from the cooking cavity to the outside, thus reducing the impact on the normal operation of external electrical components and on cooking efficiency and effect. This effectively improves the performance stability and safety of the air fryer, ensuring its cooking efficiency and effect.

[0011] In one optional embodiment, the machine body is provided with an air outlet assembly, which has an air outlet channel. One end of the air outlet channel is connected to the cooking cavity, and the other end is connected to the atmosphere. By providing the air outlet assembly connecting the cooking cavity and the atmosphere in the machine body, excess water vapor in the cooking cavity can be better discharged, preventing water vapor from accumulating and forming condensation, which would affect the cooking effect.

[0012] In one optional embodiment, the machine body is provided with a heat dissipation duct communicating with the atmosphere. A heat dissipation component is housed within the heat dissipation duct, and the duct at least partially surrounds the air outlet component and the cooking cavity. By providing a heat dissipation duct communicating with the atmosphere within the machine body and surrounding the air outlet component and the cooking cavity, not only can the cooling airflow within the duct dissipate heat to the air outlet component, reducing the outlet air temperature and minimizing the risk of burns to the user, but the cooling airflow within the duct can also dissipate heat to the cooking cavity, reducing the outward transfer of high temperatures from the cooking cavity and thus minimizing the impact on the normal operation of external electrical components within the cooking cavity. This effectively ensures the performance stability and safety of the air fryer.

[0013] In one optional embodiment, the unit body is equipped with a water tank, and the unit body is equipped with a steam generating system for generating steam, the steam generating system being adapted to connect to the cooking chamber; the unit body is also equipped with a liquid delivery system, the liquid delivery system being adapted to connect the water tank and the steam generating system. By providing a steam generating system connected to the cooking chamber within the unit body, steam cooking of the air fryer can be achieved, effectively improving the functional versatility and applicability of the air fryer.

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

[0015] This application achieves a sealed connection between the frying basket and the side wall of the cooking cavity by setting a step on the side wall of the cooking cavity corresponding to the flange, and setting a first sealing element on the step that seals with the lower side of the flange. This effectively prevents water vapor in the cooking cavity from flowing to the bottom of the cooking cavity through the connection gap between the frying basket and the side wall of the cooking cavity, thereby preventing condensation from forming at the bottom of the cooking cavity and 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.

[0020] 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.

[0021] 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.

[0022] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0025] Appendix Figure 1 To be continued Figure 3 The diagram shown is a schematic of an air fryer with good sealing provided by this utility model. The air fryer includes a body 10, a cooking chamber 11 with an open front side inside the body 10, and a hot air circulation system 20 communicating with the cooking chamber 11. The hot air circulation system 20 is adapted to generate circulating heat flow and introduce it into the cooking chamber 11 to cook the food in the cooking chamber 11.

[0026] like Figure 1 and Figure 2As shown, a frying basket 30 with a top opening is detachably provided inside the cooking cavity 11 through a side opening. The frying basket 30 has an outwardly folded flange 31 around the periphery of the top opening. A step 111 corresponding to the flange 31 is provided on the side wall of the cooking cavity 11. A first sealing element 40 is provided on the step 111. When the frying basket 30 is installed in the cooking cavity 11, the lower side of the flange 31 is adapted to seal with the first sealing element 40. By providing the step 111 corresponding to the flange 31 on the side wall of the cooking cavity 11, and providing the first sealing element 40 on the step 111 to seal with the lower side of the flange 31, a sealed connection between the frying basket 30 and the side wall of the cooking cavity 11 can be achieved. This effectively prevents water vapor in the cooking cavity 11 from flowing through the connection gap between the frying basket 30 and the side wall of the cooking cavity 11 to the bottom of the cooking cavity 11, thus preventing condensation at the bottom of the cooking cavity 11 and effectively improving the user experience.

[0027] like Figures 1 to 3 As shown, in an optional embodiment, the bottom of the cooking cavity 11 is provided with a lower core 12 that constitutes at least part of the cooking cavity 11, and an upper core 13 is provided above the lower core 12. The lower core 12 has a top opening, and the periphery of the top opening is provided with a first sealing member 40. The lower core 12 is adapted to abut against the upper core 13 through the first sealing member 40. By clamping the first sealing element 40 between the upper core 13 and the lower core 12, a sealed connection between the upper core 13 and the lower core 12 can be achieved. This not only prevents the circulating heat flow and / or water vapor in the cooking cavity 11 from flowing out of the cooking cavity 11 through the connection gap between the upper core 13 and the lower core 12, thus avoiding any impact on the normal operation of the electrical components outside the cooking cavity 11, but also effectively ensures the performance stability and safety of the air fryer.

[0028] like Figure 1 and Figure 3As shown, in an optional embodiment, the lower movement 12 has a downwardly recessed mounting groove 121 around the top opening. The lower side of the first seal 40 has a mounting portion 41 that matches the mounting groove 121, and the mounting portion 41 is at least partially confined within the mounting groove 121. The mounting groove 121 is adapted to position the first seal 40 during installation, effectively reducing the installation difficulty of the first seal 40. Simultaneously, the mounting groove 121 is adapted to limit the first seal 40, reducing the possibility of poor sealing caused by deformation or displacement of the first seal 40 due to compression between the upper and lower movements 13 during installation, thus effectively ensuring the sealing stability when the upper and lower movements 12 are connected.

[0029] like Figures 1 to 3 As shown, in an optional embodiment, an air duct plate 14 is provided at the top of the cooking cavity 11, and the upper core 13 is provided above the air duct plate 14. A second sealing element 50 matching the periphery of the air duct plate 14 is sandwiched between the air duct plate 14 and the upper core 13. The air duct plate 14 is adapted to be sealed with the upper core 13 through the second sealing element 50. By sandwiching the second sealing element 50 matching the periphery of the air duct plate 14 between the air duct plate 14 and the upper core 13, a sealed connection between the upper core 13 and the air duct plate 14 can be achieved, preventing the circulating heat flow and / or water vapor in the cooking cavity 11 from flowing out of the cooking cavity 11 through the connection gap between the upper core 13 and the air duct plate 14, thereby affecting the normal operation of the electrical components outside the cooking cavity 11 and effectively ensuring the performance stability and safety of the air fryer.

[0030] like Figure 1 and Figure 3As shown, in an optional embodiment, the upper core 13 has an upwardly recessed sealing groove 131 on the side facing the air duct plate 14, and the second sealing member 50 is at least partially confined within the sealing groove 131. In the air fryer, the sealing groove 131 is adapted to position the second sealing member 50 during installation. Positioning the second sealing member 50 through the sealing groove 131 effectively reduces the installation difficulty of the second sealing member 50. At the same time, the sealing groove 131 is also adapted to limit the installation of the second sealing member 50. Limiting the second sealing member 50 through the sealing groove 131 reduces the possibility of poor sealing caused by the compression deformation or displacement of the upper core 13 and the air duct plate 14, effectively ensuring the sealing stability when the upper core 13 and the air duct plate 14 are connected.

[0031] In an optional embodiment, the first seal 40 and the second seal 50 are preferably made of elastic, high-temperature resistant materials such as rubber and silicone. By using elastic, high-temperature resistant materials such as rubber and silicone to make the first seal 40 and the second seal 50, the impact of the high temperature inside the cooking cavity 11 on the first seal 40 and the second seal 50 can be reduced, effectively ensuring the sealing stability and sealing effect of the first seal 40 and the second seal 50.

[0032] like Figures 1 to 3As shown, in an optional embodiment, the top of the cooking cavity 11 is provided with a hot air cavity 141 with an upwardly recessed opening formed by the air duct plate 14. The hot air cavity 141 is provided with the hot air circulation system 20, and the opening of the hot air cavity 141 is adapted to correspond to the top opening of the frying basket 20. By setting the opening of the hot air cavity 141 to correspond to the top opening of the frying basket 20, the circulating heat generated by the hot air circulation system 20 can circulate better between the frying basket 30 and the hot air cavity 141, effectively improving the cooking efficiency and cooking effect of the food in the frying basket 30. At the same time, by setting the opening of the hot air cavity 141 to correspond to the top opening of the frying basket 30, the outflow of water vapor generated during cooking to the outside of the frying basket 30, which would cause condensation at the bottom of the cooking cavity 11 and result in a poor user experience, can also be reduced. Furthermore, by setting the opening of the hot air cavity 141 to correspond to the top opening of the frying basket 30, not only can the outflow of circulating heat flow and / or water vapor from the cooking cavity 11 to the outside of the cooking cavity 11 be reduced, thereby affecting the normal operation of the electrical components outside the cooking cavity 11, but also the outflow of circulating heat flow and / or water vapor from the cooking cavity 11 to the outside of the cooking cavity 11, thereby affecting the cooking efficiency and cooking effect of the air fryer, effectively improving the performance stability and safety of the air fryer, and ensuring the cooking efficiency and cooking effect of the air fryer.

[0033] like Figure 1 As shown, in an optional embodiment, the body 10 is provided with an air outlet assembly 15, which has an air outlet channel 151. One end of the air outlet channel 151 is connected to the cooking chamber 11, and the other end is connected to the atmosphere. By providing the air outlet assembly 15 connecting the cooking chamber 11 and the atmosphere within the body 10, excess water vapor in the cooking chamber 11 can be better discharged, thus preventing water vapor from accumulating and forming condensate, which would affect the cooking effect.

[0034] like Figure 1As shown, in an optional embodiment, the body 10 is provided with a heat dissipation duct 16 communicating with the atmosphere. The heat dissipation duct 16 is provided with a heat dissipation component 60 for generating a cooling current. The heat dissipation duct 16 at least partially surrounds the air outlet component 15 and the cooking cavity 11. By providing the heat dissipation duct 16 communicating with the atmosphere within the body 10 and surrounding the air outlet component 15 and the cooking cavity 11, not only can the cooling current within the heat dissipation duct 16 be used to dissipate heat from the air outlet component 15, reducing the outlet temperature and minimizing the risk of burns to the user, but the cooling current within the heat dissipation duct 16 can also be used to dissipate heat from the cooking cavity 11, reducing the transfer of high temperatures from the cooking cavity 11 to the outside, thus minimizing the impact on the normal operation of the external electrical components of the cooking cavity 11. This effectively ensures the performance stability and safety of the air fryer.

[0035] like Figure 1 As shown, in an optional embodiment, the body 10 is provided with a water tank 70, and the body 10 is provided with a steam generating system for generating steam, the steam generating system being adapted to connect with the cooking chamber 11; the body 10 is provided with a liquid delivery system, the liquid delivery system being adapted to connect the water tank 70 and the steam generating system. The water tank 70 is adapted to store water, and the liquid delivery system is adapted to deliver the water in the water tank 70 to the steam generating system, so that the water is converted into steam by the steam generating system and then introduced into the cooking chamber 11, thereby steam cooking the food in the cooking chamber 11. Therefore, by providing the steam generating system connected to the cooking chamber 11 in the body 10, steam cooking of the air fryer can be realized, effectively improving the functional versatility and applicability of the air fryer.
