Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a protective net and an air fryer. Background Technology

[0002] An air fryer is a cooking appliance that uses rapidly circulating hot air to heat food, achieving the effect and texture of fried food. An air fryer contains a hot air unit and a cooking chamber, separated by a protective mesh. When the air fryer is operating, the hot air generated by the hot air unit can pass through the protective mesh into the cooking chamber. However, the protective mesh increases airflow resistance during operation, resulting in lower hot air circulation efficiency. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, this utility model proposes a protective net that can increase the ventilation area of ​​the air fryer when it is working, which is beneficial to improving the hot air circulation efficiency of the air fryer.

[0005] This utility model also proposes an air fryer.

[0006] The protective net of this utility model has a ventilation area opposite to the hot air device. The protective net can be switched between an open state and a retracted state. In the open state, the ventilation area of ​​the ventilation area is A, and in the retracted state, the ventilation area of ​​the ventilation area is B, wherein B > A.

[0007] According to this invention, the protective net can be switched between an open and a retracted state. The ventilation area A in the open state is larger than the ventilation area B in the retracted state. Therefore, when the air fryer is not in operation, the protective net can be switched to the open state, reducing the ventilation area and thus lowering the probability of the user directly contacting the hot air device. When the air fryer is in operation, the protective net can be switched to the retracted state, increasing the ventilation area and reducing the resistance of hot air passing through the net, thereby improving the hot air circulation efficiency of the air fryer.

[0008] Optionally, the protective net includes an outer ring and multiple wire mesh sections, all located inside the outer ring and arranged sequentially along the circumference of the outer ring. At least one of the multiple wire mesh sections is switchable between an open state and a retracted state. Because the multiple wire mesh sections are arranged sequentially along the circumference of the outer ring, when the protective net is in the open state, they can collectively protect the hot air device, preventing direct contact between the user's hands and the hot air device, thereby improving the protective effect of the net. Furthermore, since at least one of the multiple wire mesh sections is switchable between an open state and a retracted state, the relative positions of the wire mesh sections can be changed to increase or decrease the ventilation area of ​​the ventilation zone, facilitating the manufacturing of the protective net.

[0009] Optionally, the mesh section is made of shape-memory metal. The mesh section has different shapes at a first preset temperature and a second preset temperature, where the first preset temperature is higher than the second preset temperature. When the temperature of the protective net is at the first preset temperature, the protective net deforms into a contracted state; when the temperature of the protective net is at the second preset temperature, the protective net deforms into an open state. Because shape-memory metal has a memory function, the mesh section can be set to different shapes at the first and second preset temperatures. When the air fryer is working, the temperature inside the cooking cavity rises, and the temperature of the protective net rises accordingly. Since the first preset temperature is higher than the second preset temperature, the protective net can deform into a contracted state when its temperature is at the first preset temperature. Therefore, the protective net can automatically switch to a contracted state when the air fryer is working to reduce the resistance of hot air passing through the protective net. Furthermore, the structural design is simple and requires no additional drive source.

[0010] Optionally, when the protective net switches from the open state to the retracted state, the mesh portion moves towards the outer ring; when the protective net switches from the retracted state to the open state, the mesh portion moves towards the center of the ventilation area. This simplifies the switching mechanism of the protective net and reduces its space requirements.

[0011] Optionally, the wire mesh section includes multiple wires connected to the outer ring, with ventilation gaps between adjacent wires. Thus, the protective net can both guide airflow through these gaps and prevent the user's hands from directly contacting the hot air device. Furthermore, the wire mesh section has a simple structural design and is easy to manufacture.

[0012] Optionally, when the protective net switches from the open state to the retracted state, the size of the ventilation gap gradually decreases, and the ventilation area of ​​the ventilation zone gradually increases; conversely, when the protective net switches from the retracted state to the open state, the size of the ventilation gap gradually increases, and the ventilation area of ​​the ventilation zone gradually decreases. The protective net of this invention is designed with the above structure, which facilitates the processing and manufacturing of the protective net, and the state switching method of the protective net is simple, occupying less space.

[0013] The air fryer of this utility model includes: a housing, wherein a heating chamber and a cooking chamber are provided inside the housing; a hot air device, wherein the hot air device is disposed inside the heating chamber; and a protective net, wherein the protective net is the same as that described in any one of this utility model, and the protective net is disposed between the heating chamber and the cooking chamber.

[0014] According to this invention, the air fryer's protective net can be switched between an open and retracted state. The ventilation area A in the open state is larger than the ventilation area B in the retracted state. Therefore, when the air fryer is not in operation, the protective net can be switched to the open state, reducing the ventilation area of ​​the net and thus lowering the probability of the user directly contacting the hot air device. When the air fryer is in operation, the protective net can be switched to the retracted state, increasing the ventilation area of ​​the net to reduce the resistance of hot air passing through it and improve the air fryer's hot air circulation efficiency.

[0015] Optionally, the air fryer further includes a drive device for switching the protective net between the open and retracted states. Since the protective net's state switching is controlled by the drive device, the switching of the protective net's state becomes more reliable.

[0016] Optionally, the protective net includes an outer ring and multiple mesh sections, all of which are located inside the outer ring and arranged sequentially along the circumference of the outer ring. The driving device includes an electromagnetic component. When the electromagnetic component is energized, the mesh sections move towards the outer ring under magnetic influence, thereby switching the protective net to the contracted state. When the electromagnetic component is de-energized, the mesh sections can move towards the center of the ventilation area, thereby resetting the protective net to the open state. This invention's air fryer, by employing the above-described structure for the driving device, facilitates convenient switching of the protective net's state, and is simple to manufacture and has a low cost.

[0017] Optionally, the air fryer further includes an inner pot and a trigger switch. The inner pot is removably installed in the cooking cavity. The trigger switch cooperates with the inner pot and is electrically connected to the electromagnetic component. When the inner pot is removed from the cooking cavity, the trigger switch controls the circuit of the electromagnetic component to disconnect. When the inner pot is inserted into the cooking cavity, the trigger switch controls the circuit of the electromagnetic component to connect. Thus, when the user removes the inner pot from the cooking cavity or inserts it into the cooking cavity, the trigger switch can automatically control the circuit of the electromagnetic component to be energized, thereby making the state switching of the protective net more intelligent and improving the user experience.

[0029] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The following is a reference appendix. Figures 1 to 6 This invention describes a protective net and an air fryer according to embodiments of the present invention.

[0031] like Figures 1 to 3 As shown, the protective net 1 of this embodiment of the present invention has a ventilation area 101 opposite to the hot air device 3 (e.g., Figure 1 and Figure 3 (The area of ​​the dotted circle in the middle) The protective net 1 can be switched between an open state and a retracted state. In the open state, the ventilation area of ​​the ventilation area 101 is A, and in the retracted state, the ventilation area of ​​the ventilation area 101 is B, where B > A.

[0032] According to the embodiment of the present invention, the protective net 1 is switchable between an open state and a retracted state. The ventilation area A of the ventilation zone 101 in the open state is greater than the ventilation area B of the ventilation zone 101 in the retracted state. Therefore, when the air fryer is not in operation, the protective net 1 can be switched to the open state, reducing the ventilation area of ​​the ventilation zone 101 and thus reducing the probability of the user directly contacting the hot air device 3. When the air fryer is in operation, the protective net 1 can be switched to the retracted state to increase the ventilation area of ​​the ventilation zone 101, thereby reducing the resistance of hot air passing through the protective net 1 and improving the hot air circulation efficiency of the air fryer.

[0033] When the protective net 1 is switched to the open state, the ventilation area of ​​the ventilation zone 101 of the protective net 1 can be reduced, which reduces the probability that the user will directly contact the hot air device 3. On the one hand, it can avoid the problem of the user being burned by contacting the hot air device 3. On the other hand, the fragile parts (e.g., oven lamp or far-infrared tube) in the heating chamber 21 can also be protected by the protective net 1 to avoid damage to the fragile parts due to bumps.

[0034] like Figure 1 As shown, when the protective net 1 is in the open state, the ventilation area 101 of the protective net 1 is relatively small because the ventilation area 101 is partially blocked by the wire mesh structure. Figure 3 As shown, when the protective net 1 is in the retracted state, since the ventilation area 101 of the protective net 1 is open and there is no wire mesh structure to block it, the ventilation area 101 of the protective net 1 is larger when it is in the retracted state, so as to reduce the resistance of hot air passing through the protective net 1 and improve the hot air circulation efficiency of the air fryer.

[0035] It is understood that the switching between the open and retracted states of the protective net 1 can be achieved by deforming the protective net 1 itself or by changing the position of the protective net 1. This utility model does not limit this to either of these methods.

[0036] Optionally, such as Figures 1 to 3 As shown, the protective net 1 includes an outer ring 11 and multiple mesh sections 12. The mesh sections 12 are all located inside the outer ring 11 and arranged sequentially along the circumference of the outer ring 11. At least one of the mesh sections 12 can switch between an open state and a retracted state. Since the mesh sections 12 are arranged sequentially along the circumference of the outer ring 11, when the protective net 1 is in the open state, the mesh sections 12 can collectively protect the hot air device 3, preventing direct contact between the user's hands and the hot air device 3, thereby improving the protective effect of the protective net 1. Because at least one of the mesh sections 12 can switch between an open state and a retracted state, the ventilation area of ​​the ventilation zone 101 can be increased or decreased by changing the relative positions of the mesh sections 12, facilitating the manufacturing of the protective net 1. Furthermore, when assembling the protective net 1, the outer ring 11 can be connected to the housing 2 without affecting the switching of the mesh sections 12.

[0037] For example, multiple mesh sections 12 are switchable between an open state and a retracted state, which makes the ventilation area 101 of the protective net 1 smaller in the retracted state, further reducing the resistance of hot air passing through the protective net 1 and improving the hot air circulation efficiency of the air fryer.

[0038] Optionally, the wire mesh portion 12 is made of shape memory metal. The wire mesh portion 12 has different forms at a first preset temperature and a second preset temperature. The first preset temperature is greater than the second preset temperature. When the temperature of the protective net 1 is at the first preset temperature, the protective net 1 deforms to a contracted state. When the temperature of the protective net 1 is at the second preset temperature, the protective net 1 deforms to an open state.

[0039] Understandably, because shape memory metal has a memory function, the mesh section 12 can be set into different shapes at the first preset temperature and the second preset temperature. When the air fryer is working, the temperature inside the cooking cavity 22 rises, and the temperature of the protective mesh 1 will rise accordingly. Since the first preset temperature is greater than the second preset temperature, when the temperature of the protective mesh 1 is at the first preset temperature, the protective mesh 1 can deform to a contracted state. Therefore, the protective mesh 1 can automatically switch to a contracted state when the air fryer is working, so as to reduce the resistance when hot air passes through the protective mesh 1. Moreover, the structural design is simple and does not require an additional drive source.

[0040] Similarly, when the air fryer stops working, the temperature inside the cooking cavity 22 gradually decreases, and the temperature of the protective net 1 will also decrease. Thus, the protective net 1 can automatically switch to the open state when the air fryer stops working to protect the fragile parts inside the heating cavity 21.

[0041] like Figure 2 and Figure 3As shown, when the protective net 1 switches from an open state to a retracted state, the wire mesh part 12 moves along the direction close to the outer ring 11. When the protective net 1 switches from a retracted state to an open state, the wire mesh part 12 moves along the direction close to the center of the ventilation area 101. This makes the state switching method of the protective net 1 simple and occupies less space.

[0042] like Figure 1 and Figure 2 As shown, when the protective net 1 is in the open state, multiple mesh sections 12 extend toward the center of the ventilation area 101, thereby covering the ventilation area 101 of the protective net 1 with the mesh sections 12, reducing the probability that the user's hand will come into contact with the hot air device 3 through the ventilation area 101, which is beneficial to improving the protective effect of the protective net 1.

[0043] like Figure 3 As shown, when the protective net 1 is in a retracted state, the multiple mesh sections 12 are spaced a certain distance from the center of the ventilation area 101, thereby increasing the ventilation area of ​​the ventilation area 101 so that hot air can pass through the protective net 1 and reduce the resistance during hot air circulation.

[0044] Optionally, such as Figure 2 and Figure 3 As shown, the wire mesh section 12 includes multiple wires 121 connected to the outer ring 11, with ventilation gaps 102 between adjacent wires 121. Because multiple wires 121 are connected to the outer ring 11, the stability of the connection between the wire mesh section 12 and the outer ring 11 is improved. Furthermore, the ventilation gaps 102 between adjacent wires 121 allow for airflow guidance while preventing direct contact between the user's hands and the hot air device 3. The wire mesh section 12 also features a simple structural design, facilitating manufacturing.

[0045] For example, when the protective net 1 switches from an open state to a retracted state, the size of the ventilation gap 102 gradually decreases, and the ventilation area of ​​the ventilation region 101 gradually increases. Conversely, when the protective net 1 switches from a retracted state to an open state, the size of the ventilation gap 102 gradually increases, and the ventilation area of ​​the ventilation region 101 gradually decreases. The protective net 1 of this embodiment is designed with the above structure, which facilitates the processing and manufacturing of the protective net 1, and the state switching method of the protective net 1 is simple, occupying less space.

[0046] It is understandable that the multiple wires 121 of the wire mesh section 12 can change position under the action of external force or its own memory function. When the protective net 1 switches from the open state to the retracted state, the multiple wires 121 move closer to each other, so that the size of the ventilation gap 102 gradually decreases. At this time, the opening area of ​​the wire mesh section 12 will also decrease synchronously (that is, the wire mesh section 12 retracts towards the outer ring 11, so that the opening area of ​​the wire mesh section 12 becomes smaller), thereby making the ventilation area of ​​the ventilation zone 101 gradually increase.

[0047] When the protective net 1 switches from a contracted state to an open state, the multiple wires 121 move away from each other, so that the size of the ventilation gap 102 gradually increases. At this time, the opening area of ​​the wire mesh 12 also increases synchronously (that is, the wire mesh 12 opens towards the center of the ventilation area 101, so that the opening area of ​​the wire mesh 12 increases), thereby making the ventilation area of ​​the ventilation area 101 gradually decrease.

[0048] like Figures 4 to 6 As shown, the air fryer of this embodiment includes a housing 2, a hot air device 3, and a protective net 1. The housing 2 contains a heating chamber 21 and a cooking chamber 22. The hot air device 3 is located within the heating chamber 21. The protective net 1 is the protective net 1 of this invention, positioned between the heating chamber 21 and the cooking chamber 22. Figure 6 As shown, the hot air device 3 includes a fan 31 and a heating element 32. The fan 31 is located on the lower side of the heating element 32, and the protective net 1 is located on the lower side of the heating element 32. The ventilation area 101 is arranged opposite to the fan 31 and the heating element 32 in the vertical direction.

[0049] According to the embodiments of the present invention, the air fryer with a protective net 1 that can be switched between an open and a retracted state has a larger ventilation area A in the open state than in the retracted state. Therefore, when the air fryer is not in operation, the protective net 1 can be switched to the open state, reducing the ventilation area of ​​the ventilation area 101 and thus lowering the probability of the user directly contacting the hot air device 3. When the air fryer is in operation, the protective net 1 can be switched to the retracted state, increasing the ventilation area of ​​the ventilation area 101 to reduce the resistance of hot air passing through the protective net 1 and improve the hot air circulation efficiency of the air fryer.

[0050] Optionally, the air fryer also includes a drive unit (not shown) for switching the protective net 1 between an open and retracted state. Since the protective net 1's state switching is controlled by the drive unit, the state switching of the protective net 1 can be made more reliable.

[0051] In one example, such as Figures 1 to 3As shown, the protective net 1 includes an outer ring 11 and multiple mesh sections 12. The mesh sections 12 are all located inside the outer ring 11 and arranged sequentially along the circumference of the outer ring 11. The driving device includes an electromagnetic component (not shown). When the electromagnetic component is energized, the mesh sections 12 move along the direction closer to the outer ring 11 under magnetic influence, causing the protective net 1 to switch to a contracted state. When the electromagnetic component is de-energized, the mesh sections 12 can move along the direction closer to the center of the ventilation area 101, causing the protective net 1 to return to an open state. The air fryer of this embodiment, by adopting the above-described structure for the driving device, facilitates the switching of the protective net 1's state, and is simple to manufacture and has a low cost.

[0052] It is understood that the wire mesh portion 12 is made of metal (e.g., stainless steel) and has a certain degree of elasticity. The electromagnetic component is arranged near the outer ring 11 of the protective net 1. When the electromagnetic component is energized, the wire mesh portion 12 can be attracted by the magnetic field generated by the electromagnetic component, so that the multiple wires 121 of the wire mesh portion 12 move closer to each other, thereby reducing the size of the ventilation gap 102 and increasing the ventilation area of ​​the ventilation zone 101. When the electromagnetic component is de-energized, the magnetic field of the electromagnetic component disappears, and the multiple wires 121 of the wire mesh portion 12 elastically return to their initial position, that is, the wire mesh portion 12 returns to the open state, thereby completing the state switching of the protective net 1.

[0053] Optionally, such as Figures 1 to 3 and Figure 6 As shown, the air fryer also includes an inner pot 4 and a trigger switch (not shown). The inner pot 4 is removably installed in the cooking cavity 22. The trigger switch is engaged with the inner pot 4 and is electrically connected to the electromagnetic component. When the inner pot 4 is pulled out of the cooking cavity 22, the trigger switch controls the circuit of the electromagnetic component to disconnect. When the inner pot 4 is inserted into the cooking cavity 22, the trigger switch controls the circuit of the electromagnetic component to be turned on.

[0054] Therefore, when the user removes the inner pot 4 from the cooking cavity 22 or puts the inner pot 4 into the cooking cavity 22, the trigger switch can automatically control the circuit of the electromagnetic component to be energized, thereby making the state switching of the protective net 1 more intelligent and improving the user experience.

[0055] For example, the trigger switch is a microswitch, which is installed on the inner wall of the cooking cavity 22. When the inner pot 4 is inserted into the cooking cavity 22, the microswitch is turned on and controls the circuit of the electromagnetic component to conduct. When the inner pot 4 is removed from the cooking cavity 22, the microswitch is turned off to control the circuit of the electromagnetic component to disconnect.
