Description

Technical Field

[0001] This application belongs to the field of kitchen appliance technology, and in particular relates to an air fryer with grilling function. Background Technology

[0002] An air fryer is a cooking appliance that uses hot air instead of hot oil. It relies on rapidly circulating hot air to remove surface moisture from food, achieving a similar effect to deep-frying (i.e., using high-temperature "air" as a medium to "fry" food). Air fryers are popular because they reduce the amount of oil used, thus lowering the intake of fats.

[0003] Existing air fryers generally use a design where the motor and heating element are located at the top of the machine, while the frying basket and frying pot are placed at the bottom. Due to structural limitations, air fryers are not convenient for frying or grilling, resulting in limited functionality and restricting user interaction. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the purpose of this application is to provide an air fryer with a heating plate assembly that can be raised and lowered to simultaneously have a grilling function.

[0005] The technical solution adopted in this application embodiment is an air fryer, comprising:

[0006] The lower shell assembly includes a shell and a heating plate assembly. The heating plate assembly is movably disposed within the shell via an elastic member so as to be able to rise and fall relative to the shell and have a highest position near the top of the shell and a lowest position near the bottom of the shell.

[0007] The upper cover assembly is rotatably disposed on top of the lower shell assembly and has a closed state that covers the lower shell assembly and an open state that rotates away from the lower shell assembly to expose the heating plate assembly.

[0008] A pot assembly that can be disposed within the housing and press the heating plate assembly down to the lowest position;

[0009] A frying pan, used to place on the heating plate assembly when the heating plate assembly is in the highest position, for frying or grilling food.

[0010] In some embodiments, the upper cover assembly is provided with a heating device. When the pot assembly is placed inside the housing and the upper cover assembly is closed, the heating device is used to air-fry the food inside the pot assembly. By providing a heating device on the upper cover assembly, the inner cavity of the pot assembly can be sealed to form a cooking cavity when the upper cover assembly is closed, and the heat generated by the heating device can be used to air-fry the food inside the pot assembly.

[0011] In some embodiments, the elastic member includes a guide post and a spring. The guide post is vertically arranged, with its lower end fixed to the bottom of the housing and its upper end passing through the heating plate assembly and fixed to the top of the housing. The spring is sleeved on the guide post, with its upper end abutting against the bottom of the heating plate assembly, and is used to apply an upward force to the heating plate assembly, allowing the heating plate assembly to rise to the highest position under the action of the spring. The elastic member has a simple structure and enables the heating plate assembly to automatically and smoothly rise and fall, improving ease of use.

[0012] In some embodiments, a limiting block is fixed to the upper end of the guide post. When the heating plate assembly rises to the highest position under the action of the spring, the limiting block abuts against the heating plate assembly, restricting the heating plate assembly from continuing to move upward. This prevents the heating plate assembly from detaching from the housing and ensures its use in the highest position.

[0013] In some embodiments, the housing includes an outer shell, an inner shell, and a top frame. The inner shell is disposed within the outer shell, and a heat-insulating cavity is formed between the inner shell and the outer shell. The top frame is disposed at the top of the outer shell and the inner shell to cover the top of the heat-insulating cavity. The heating plate assembly and the elastic member are both disposed within the inner shell. The housing has a reasonable structural form, which can prevent the heat generated by the heating plate assembly from being transferred to the outside, reduce energy consumption, and improve cooking efficiency.

[0014] In some embodiments, the bottom of the inner shell is provided with a recess, and the lower end of the guide post is embedded and fixed in the recess; and / or

[0015] The upper end of the guide post is fixed with a limiting block that restricts the heating plate assembly from rising further when it reaches the highest position. The limiting block has a fixing part that extends between the upper frame and the top of the inner shell, and the upper frame presses the fixing part against the top of the inner shell. The guide post can be reliably fixed by providing a recess; the limiting block with the fixing part can further ensure the stability of the guide post.

[0016] In some embodiments, the bottom periphery of the inner shell is provided with a plurality of recesses; the air fryer includes a plurality of elastic members, the lower ends of a plurality of guide posts of the plurality of elastic members are respectively disposed in the recesses, and the upper ends of a plurality of springs respectively sleeved on the plurality of guide posts abut against the periphery of the heating plate assembly, for applying an upward balanced force to the heating plate assembly from the periphery.

[0017] In some embodiments, a fastener is provided at the top of the housing;

[0018] The pot assembly includes a pot body and a locking member located on the outer periphery of the upper end of the pot body. When the pot body is placed inside the housing and the heating plate assembly is pressed down to the lowest position, the locking member engages with the latch to restrain the pot body on the housing, thus keeping the heating plate assembly in the lowest position. This prevents the pot body from moving upwards and detaching from the housing.

[0019] In some embodiments, the top of the housing is provided with a downwardly recessed groove, the groove extending to the outer periphery of the housing to form a side slot, and the upper part of the rear sidewall of the groove protruding towards the side slot to form the fastener;

[0020] The locking component includes a latch, a button, and a reset member. The latch is movably disposed on the upper outer periphery of the pot body, with one end forming a tongue and the middle portion having an inclined surface. The button is disposed on the pot body and has a pushing inclined surface that abuts against the inclined surface of the latch. When the button is pressed, the pushing inclined surface pushes the inclined surface, causing the latch to move away from the groove in a first direction, thereby disengaging the tongue from the latch. The reset member acts on the latch to push it towards the groove in a second direction when the button is released, causing the tongue to engage with the latch. This locking component has a simple and reasonable structure, is easy to control, and facilitates locking and unlocking of the pot body and the shell.

[0021] In some embodiments, two handles are symmetrically provided on the outer periphery of the upper end of the pot body, and each of the two handles is provided with a mounting cavity. The side of the handle near the pot body is provided with an opening communicating with the mounting cavity, and the lower part of the handle is provided with a mounting port communicating with the mounting cavity.

[0022] The pot assembly includes two locking members. The latches and reset members of the two locking members are respectively disposed in the mounting cavities of the two handles. The latch tongue can enter and exit the mounting cavity through the opening to disengage or engage with the latch. One end of the button has a pushing slope and extends into the mounting cavity through the mounting opening to abut against the inclined surface of the latch. The other end of the button is located outside the mounting cavity and forms a pressing part. Placing the locking members on the handles makes it convenient and quick to remove and place the pot assembly within the housing.

[0023] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: the air fryer of this application can realize the lifting and lowering of the heating plate assembly within the shell through the elastic component, and when used with the grilling plate and pot assembly, it can realize the grilling and air frying of food, increasing the cooking function of the air fryer and meeting the user's interactive needs for multiple cooking methods.

[0042] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0043] like Figures 1 to 8 As shown, this application provides an air fryer, which includes a lower shell assembly 1, an upper cover assembly 2, a pot assembly 3, and a grilling pan 4. The lower shell assembly 1 includes a shell 11 and a heating plate assembly 12. The shell 11 has a cavity that extends to the top of the shell 11 to form an opening, i.e., the shell 11 has an open top structure. The heating plate assembly 12 is movably disposed within the cavity of the shell 11 by an elastic member 13. Under the action of the elastic member 13, the heating plate assembly 12 can rise and fall within the cavity, reaching its highest position near the top of the shell 11 (see...). Figure 3 and Figure 4 ) and the lowest position near the bottom of housing 11 (see Figure 5 and Figure 6 ),in Figure 5 The arrows indicate the direction of movement of the heating plate assembly 12. The upper cover assembly 2 is rotatably mounted on top of the lower shell assembly 1 and has a closed state that covers the lower shell assembly 1 and an open state that rotates away from the lower shell assembly 1 to expose the heating plate assembly 12. The pot assembly 3 can be disposed inside the shell 11 and press the heating plate assembly 12 down to the lowest position. The grilling pan 4 is used to place on the heating plate assembly 12 when it is in the highest position to grill food.

[0044] The air fryer of this application embodiment has a liftable heating plate assembly 12 installed in the shell 11 by an elastic member 13. When the heating plate assembly 12 rises to the highest position, it is used for grilling by the grilling plate 4 placed on it. When the heating plate assembly 12 is lowered to the lowest position under the action of the pot assembly 3, it can be used for air frying or steaming, etc., thereby increasing the cooking function of the air fryer and satisfying the interactive use of different cooking modes.

[0045] In some embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, the upper cover assembly 2 is equipped with a heating device 21. When the pot assembly 3 is placed inside the shell 11 and the upper cover assembly 2 is closed, the heating device 21 can be used to air-fry the food inside the pot assembly 3. By setting the heating device 21 on the upper cover assembly 2, when the upper cover assembly 2 covers the lower shell assembly 1, the upper cover assembly 2 cooperates with the pot assembly 3 to seal the inner cavity of the pot assembly 3 to form a cooking cavity. The heat generated by the heating device 21 can be used to air-fry the food inside the pot assembly 3.

[0046] Understandably, to ensure that the heat generated by the heating element 21 quickly enters the pot assembly 3 and circulates, thereby improving the cooking efficiency and effect on the food inside the pot assembly 3, the upper cover assembly 2 is also equipped with a cold air fan 22, a hot air fan 23, and a motor 24. The motor 24 is connected to both the cold air fan 22 and the hot air fan 23, driving their rotation. The hot air fan 23 is positioned close to the heating element 21 to deliver airflow, generating a hot airflow that enters the pot assembly 3 and air-fryes the food inside. The cold air fan 22 is positioned close to the motor 24 to dissipate heat, preventing the motor 24 from overheating and affecting normal operation.

[0047] The heating device 21 can be a heating tube, which can be coiled into a disc shape and positioned directly in front of the inner cavity of the pot assembly 3 to achieve uniform heating of the food inside the cavity.

[0048] Furthermore, the bottom of the pot assembly 3 can be approximately flat. When the pot assembly 3 is placed inside the housing 11, the bottom of the pot assembly 3 is in contact with the upper surface of the heating plate assembly 12, pressing the heating plate assembly 12 down to its lowest position. Because the pot assembly 3 is in contact with the heating plate assembly 12, the heat generated by the heating plate assembly 12 can be quickly conducted to the pot assembly 3, enabling cooking operations such as steaming and boiling of the food inside the pot assembly 3.

[0049] The elastic member 13 in this application refers to a structure capable of elastic deformation, which enables the heating plate assembly 12 to rise and fall. The elastic member 13 may, for example, take the form of multiple elastic columns.

[0050] In some embodiments, such as Figures 3 to 5 As shown, the elastic member 13 includes a guide post 131 and a spring 132. The guide post 131 is vertically arranged, with its lower end fixed to the bottom of the housing 11 and its upper end passing through the heating plate assembly 12 and fixed to the top of the housing 11. The spring 132 is sleeved on the guide post 131, and its upper end abuts against the bottom of the heating plate assembly 12, applying an upward force to the heating plate assembly 12, allowing the heating plate assembly 12 to rise to its highest position under the action of the spring 132. The structure of the elastic member 13, consisting of a guide post 131 and a spring 132, is not only simple in structure but also enables the heating plate assembly 12 to automatically and smoothly rise and fall, improving ease of use.

[0051] In some embodiments, such as Figure 3 and Figure 5 As shown, a limiting block 14 is fixed to the upper end of the guide post 131. When the heating plate assembly 12 rises to its highest position under the action of the spring 132, the limiting block 14 abuts against the heating plate assembly 12, restricting the heating plate assembly 12 from continuing to move upward. By setting the limiting block 14, the upward stroke of the heating plate assembly 12 can be limited, so that the heating plate assembly 12 is limited after rising to the predetermined highest position, preventing the heating plate assembly 12 from falling out of the housing 11 and ensuring the use of the heating plate assembly 12 at the highest position. The lowest position of the heating plate assembly 12 will be limited by the bottom of the housing 11. Since the lower end of the spring 132 abuts against the bottom of the housing 11, the spring 132 is gradually compressed to the bottom of the housing 11 by the action of the pot assembly 3, and cannot be pressed down further when it is compressed to the limit state. At this time, the heating plate assembly 12 is in the lowest position. Of course, when the heating plate assembly 12 reaches the lowest position, the spring 132 may not be compressed to the limit position, but is determined by the height of the pot 31 placed in the housing 11. The lowest position is reached when the pot body 31 presses down the heating plate assembly 12.

[0052] In some embodiments, such as Figure 3As shown, the housing 11 includes an outer shell 111, an inner shell 112, and an upper frame 113. The inner shell 112 is disposed inside the outer shell 111, and the inner shell 112 and the outer shell 111 form a heat insulation cavity 114. The inner shell 112 mainly serves as heat insulation and can also be called a heat insulation plate. The upper frame 113 is disposed on the top of the outer shell 111 and the inner shell 112 to cover the top of the heat insulation cavity 114. The heating plate assembly 12 and the elastic member 13 are both disposed inside the inner shell 112. The structure of the housing 11 is reasonable. It can not only enclose the space for the heating plate assembly 12 and the elastic member 13, but also, through the sandwich structure formed by the inner shell 112 and the outer shell 111, can prevent the heat generated by the heating plate assembly 12 from being transferred to the outside, reduce energy consumption, and improve cooking efficiency.

[0053] Furthermore, such as Figure 3 As shown, the bottom of the inner shell 112 is provided with a recess 1121, and the lower end of the guide post 131 is embedded and fixed in the recess 1121. This method is not only simple in structure, but also provides stable and reliable fixation of the guide post 131.

[0054] In some embodiments, such as Figure 3 and Figure 5 As shown, the limiting block 14 is directly fixed to the upper end of the guide post 131, and the limiting block 14 has a fixing part 141 extending between the top of the upper frame 113 and the top of the inner shell 112. The upper frame 113 presses the fixing part 141 against the top of the inner shell 112. In this way, the limiting block 14 and the shell 11 are fixed together, avoiding and further ensuring the stability of the guide post 131.

[0055] In some embodiments, such as Figure 3 As shown, the bottom periphery of the inner shell 112 has multiple recesses 1121. The air fryer includes multiple elastic members 13, and the lower ends of multiple guide posts 131 of the multiple elastic members 13 are correspondingly disposed in the recesses 1121. The upper ends of multiple springs 132, which are respectively sleeved on the multiple guide posts 131, abut against the periphery of the heating plate assembly 12, and are used to apply an upward and balanced force to the heating plate assembly 12 from the periphery. By setting multiple elastic members 13, a uniform force can be applied to the heating plate assembly 12, so that the heating plate assembly 12 can be raised and lowered smoothly without tilting or shifting. For example, for an inner shell 112 structure with a rectangular cross-section, recesses 1121 can be provided at the four corners of the inner shell 112, and a guide post 131 can be provided at each recess 1121. A spring 132 is sleeved on the guide post 131. The upper end of the guide post 131 passes through the heating plate assembly 12 and is inserted into the limiting block 14 fixed between the inner shell 112 and the upper frame 113 from the bottom. The four evenly distributed elastic members 13 can ensure the smooth lifting and lowering of the heating plate assembly 12.

[0056] It is understandable that when multiple elastic components 13 are provided, the structure of the spring 132 of each elastic component 13 is exactly the same, that is, the stiffness coefficient, free length, working stroke and maximum load of the spring 132 are all the same.

[0057] In some embodiments, such as Figure 2 As shown, the top of the housing 11 is provided with a fastener 115. Figure 6 As shown, the pot assembly 3 includes a pot body 31 and a locking member 32 located on the outer periphery of the upper end of the pot body 31. When the pot body 31 is placed inside the housing 11 and the heating plate assembly 12 is pressed down to its lowest position, the locking member 32 engages with the latch 115 to restrain the pot body 31 onto the housing 11, thus keeping the heating plate assembly 12 in its lowest position. By providing the locking member 32 on the pot body 31, when the pot body 31 is placed inside the housing 11, it is restrained onto the housing 11, preventing the pot body 31 from moving upwards and detaching from the housing 11, which would affect the cooking operation.

[0058] Furthermore, continue to combine Figure 2 The top of the housing 11 is provided with a downward recessed groove 116, which extends to the outer periphery of the housing 11 to form a side slot. The upper part of the rear sidewall of the groove 116 protrudes towards the side slot to form a buckle 115.

[0059] In some embodiments, such as Figure 7 As shown, the locking member 32 includes a latch 321, a button 324, and a reset member 325. The latch 321 is movably disposed on the upper outer periphery of the pot body 31, with one end of the latch 321 forming a tongue 3211 and the middle part of the latch 321 having an inclined surface 3212. The button 324 is disposed on the pot body 31 and has a pushing inclined surface that abuts against the inclined surface 3212 of the latch 321. When the button 324 is pressed, the pushing inclined surface pushes the inclined surface 3212, causing the latch 321 to move away from the groove 116 in a first direction, so that the tongue 3211 disengages from the latch 115, and the pot body 31 can be removed from the housing 11. The reset element 325 acts on the latch 321. When the button 324 is released, the reset element 325 pushes the latch 321 to move in a second direction closer to the groove 116, causing the tongue 3211 to engage with the latch 115, locking the pot body 31 to the housing 11, preventing the pot body 31 from being removed from the housing 11, thus allowing cooking operations to proceed. The reset element 325 can be, for example, a spring. This locking component 32 has a simple and reasonable structure, is easy to control, and facilitates locking and unlocking of the pot body 31 and the housing 11.

[0060] In some embodiments, such as Figure 8As shown, two handles 33 are symmetrically arranged on the outer periphery of the upper end of the pot body 31. Each handle 33 has a mounting cavity 331. The side of the handle 33 near the pot body 31 has an opening communicating with the mounting cavity 331, and the lower part of the handle 33 has a mounting port communicating with the mounting cavity 331. The pot assembly 3 includes two locking members 32, which are respectively disposed on the two handles 33. Specifically, the latch 321 and reset member 325 of the locking member 32 are disposed in the mounting cavity 331 of the handle 33. The tongue 3211 of the latch 321 can enter and exit the mounting cavity 331 through the opening to disengage from or engage with the latch 115. One end of the button 324 has a pushing inclined surface and extends into the mounting cavity 331 through the mounting port to fit against the inclined surface 3212 of the latch 321. The other end of the button 324 is located outside the mounting cavity 331 and forms a pressing part. When the pressing part is pressed upward, the pushing slope at one end of the button 324 pushes the inclined surface 3212 of the latch 321, causing the latch 321 to move outward (i.e., away from the first direction of the groove 116). The tongue 3211 of the latch 321 disengages from the latch position 115, releasing the lock with the latch position 115, allowing the pot body 31 to be removed from the housing 11. When the pressing part is released, the reset member 325 resets and pushes the latch 321 inward (i.e., closer to the groove 116 in the second direction). The tongue 3211 of the latch 321 extends into the latch position 115, locking the pot body 31 on the housing 11. At the same time, the inclined surface 3212 of the latch 321 pushes the pushing slope of the button 324, causing the button 324 to reset.

[0061] By providing a handle 33 on the pot body 31, the pot body 31 can be placed into the housing 11 by holding the handle 33 with both hands, and the locking component 32 automatically locks the pot body 31 onto the housing 11. When it is necessary to remove the pot body 31 from the housing 11, simply hold the handle 33 again and press the pressing part upward at the same time to release the lock of the pot body 31 and remove the pot body 31 from the housing 11. The operation is convenient and quick.

[0062] It is understood that the specific structure of the heating plate assembly 12 is not limited, and it can adopt a structure similar to the heating plate 121 in a rice cooker in the prior art. In this embodiment, the heating plate assembly 12 includes a heating plate 121 and a base 122 supporting the heating plate 121. The upper surface of the heating plate 121 forms a heating surface, which can contact the bottom surfaces of the grill pan 4 and the pot body 31, transferring heat to them. The outer periphery of the base 122 can protrude radially outward from the heating plate 121, meaning the outer diameter of the base 122 is larger than the outer diameter of the heating plate 121. The upper end of the guide post 131 passes through the base 122 and connects to the limiting block 14, thus preventing the guide post 131 from passing through the heating plate 121 and affecting the heat transfer effect. Furthermore, the method by which the air fryer introduces electrical energy into the heating plate 121 is not limited; for example, it can use conventional methods found in existing technology. Moreover, the heating plate assembly 12 can maintain a connection to an external power source throughout its raising and lowering process, ensuring that the heating plate assembly 12 can generate heat at least at its highest and lowest positions. The power supply to the heating plate assembly 12 and the heating element 21 can be controlled separately via the control panel on the air fryer, allowing the heating plate assembly 12 or the heating element 21 to be activated according to different cooking methods.

[0063] The cooking process of the air fryer according to an embodiment of this application will be described below with reference to the accompanying drawings:

[0064] When it is necessary to fry or grill food, open the top cover assembly 2, hold the handles 33 on both sides of the pot body 31 with both hands, and press the button 324. The lock 321 will release the lock on the pot body 31. Pull the handles 33 upward to remove the pot body 31 from the shell 11. The spring 132 of the elastic member 13 extends and pushes the heating plate assembly 12 upward. When the heating plate assembly 12 rises to the highest position, it hits the limit block 14, stops rising, and remains at the highest position. Then, place the grilling pan 4 on the heating plate assembly 12, and you can place the food on the grilling pan 4 for frying or grilling. See below. Figure 4 In this cooking mode, the heating plate assembly 12 is working, while the heating device 21 on the upper cover assembly 2 is not working (i.e., it does not heat up).

[0065] When air frying food, first open the top cover assembly 2, place the pot body 31 into the shell 11, and insert the tongues 3211 of the locking members 32 on both sides of the pot body 31 into the latches 115 on both sides of the upper end of the shell 11 to lock the pot body 31 inside the shell 11. Simultaneously with placing the pot body 31 into the shell 11, press the heating plate assembly 12 down to its lowest position. As the heating plate assembly 12 moves downward, the spring 132 of the elastic member 13 is compressed, accumulating elastic potential energy. Then close the top cover assembly 2, start the heating device 21 and the motor 24 to generate hot airflow to air fry the food inside the pot body 31. At this time, the heating plate assembly 12 does not need to be activated and is in a non-working state.

[0066] When it is necessary to steam or boil the food, the operation process is basically the same as that of air frying. The only difference is that the heating plate assembly 12 is activated, without the need to activate the heating device 21 and the motor 24. The food in the pot body 31 is steamed or boiled using the heat generated by the heating plate assembly 12.

[0067] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
