[0036] Embodiment 1:
[0037] The present application embodiment discloses a cooking device, such as Figure 1 and Figure 2 As shown, it comprises an upper shell 1 and a lower shell 2, wherein the upper shell 1 is buckled on the lower shell 2; a reflector 11 with its opening facing downward and a hot air circulation assembly 12 located in the reflector 11 are arranged in the upper shell 1, wherein the hot air circulation assembly 12 comprises a heating element 121, a fan blade 122 and a driving motor 123 for driving the fan blade 122 to rotate. The lower shell 2 comprises an outer shell 21 with an opening at the front side and a bottom shell 22 located at the bottom of the outer shell 21 and connected to the outer shell 21, an inner lining 23 with an opening at the front side is arranged in the outer shell 21, and a bottom plate 24 connected to the inner lining 23 is correspondingly arranged on the bottom shell 22, a pot assembly 25 is arranged in the lower shell 2, and the pot assembly 25 is inserted into the lower shell 2 from the opening, and the reflector 11 and the pot assembly 25 form a cooking space.
[0038] Combination Figure 3 , Figure 4 , Figure 5 The opening of the lining 23 is provided with a first connecting piece 3, and the bottom plate 24 is provided with a second connecting piece 4 corresponding to the first connecting piece 3, and the first connecting piece 3 is connected to the second connecting piece 4 to fix the lining 23 on the bottom plate 24; the rear side of the bottom plate 24 is also provided with a third connecting piece 5, and the rear side of the bottom shell 22 is provided with a fourth connecting piece 6 corresponding to the third connecting piece 5, and the third connecting piece 5 is connected to the fourth connecting piece 6 to fix the bottom plate 24 on the bottom shell 22. The bottom plate 24, the lining 23 and the bottom shell 22 are fixedly connected together by the first connecting piece 3, the second connecting piece 4, the third connecting piece 5 and the fourth connecting piece 6, so as to ensure that the bottom plate 24 is firmly fixed between the lining 23 and the bottom shell 22, and to prevent the bottom plate 24 from loosening and shifting during thermal expansion and contraction, thereby facilitating the improvement of the quality and reliability of the cooking device.
[0039] The first connecting member 3, the second connecting member 4, the third connecting member 5 and the fourth connecting member 6 are all provided in plurality, which can further improve the connection stability between the lining 23, the bottom plate 24 and the bottom shell 22. Multiple first connecting members 3 are provided at the bottom of the lining 23, at least two first connecting members 3 are provided at both sides of the opening of the lining 23, respectively, to improve the stability at the opening of the lining 23, the remaining first connecting members 3 are evenly distributed along the circumference of the lining 23, multiple second connecting members 4 are provided at the outer edge of the bottom plate 24, and correspond one-to-one with the first connecting members 3, so as to firmly fix the lining 23 and the bottom plate 24 together; multiple third connecting members 5 are evenly distributed along the circumference of the bottom plate 24, and correspond one-to-one with the fourth connecting members 6, so as to firmly fix the bottom plate 24 and the bottom shell 22 together.
[0040] It should be noted that the first connector 3 and the second connector 4 are fixedly connected by a locking member, and the third connector 5 and the fourth connector 6 are fixedly connected by a locking member. Exemplarily, the locking member may be a fastening clip, a rivet, a screw, or other structures capable of fixing the first connector 3 and the second connector 4, and the third connector 5 and the fourth connector 6 together. Each first connector 3 is fastened to its corresponding second connector 4, and each third connector 5 is fastened to its corresponding fourth connector 6 by a locking member, so that the connection between the lining 23, the bottom plate 24, and the bottom shell 22 is more convenient and reliable.
[0041] In a possible implementation, a first locking hole 31 matching with the locking member can be provided on the first connecting member 3, and a first through hole 41 can be provided through the second connecting member 4. By inserting the locking member into the locking hole and the first through hole 41 corresponding thereto, and locking the locking member with the locking hole and the first through hole 41, the first connecting member 3 and the second connecting member 4 can be fixedly connected together. Similarly, a second locking hole 51 matching with the locking member can be provided on the third connecting member 5, and a second through hole 61 can be provided through the fourth connecting member 6. By inserting the locking member into the second locking hole 51 and the second through hole 61, the third connecting member 5 and the fourth connecting member 6 can be firmly fixed together, thereby achieving the purpose of fixing the liner 23, the bottom plate 24, and the bottom shell 22 together. The locking member can be a threaded locking member, such as a bolt, a screw, or a stud, and the locking hole and the through hole are threaded holes matching with the threaded locking member.
[0042] Among them, the first connecting member 3, the second connecting member 4, and the third connecting member 5 are all arranged in the horizontal direction. In this embodiment, the first connecting member 3 can be obtained by extending outward from the inner lining 23, and is integrally formed with the inner lining 23, thereby eliminating the connection process between the first connecting member 3 and the inner lining 23, and shortening the time required for assembly; the second connecting member 4 and the third connecting member 5 are both extended outward from the bottom plate 24, and are integrally formed with the bottom plate 24, thereby eliminating the connection process between the second connecting member 4, the third connecting member 5 and the bottom plate 24, and thus simplifying the assembly process of the air fryer.
[0043] The fourth connecting member 6 is a connecting block protruding from the bottom shell 22 , and support blocks are distributed circumferentially around the connecting block to enhance the strength of the connecting block while ensuring the connection stability between the third connecting member 5 and the fourth connecting member 6 .
[0044] It should be noted that the bottom shell 22 of a general air fryer is relatively thin, which is not convenient for setting the second through hole 61, or the second through hole 61 set on the relatively thin bottom shell 22 is not strong enough and is easy to loosen after being locked with the locking member. The fourth connecting member 6 is set as a connecting block located on the bottom shell 22, and the second through hole 61 is set on the connecting block, which is conducive to ensuring the strength of the second through hole 61 and can ensure the reliability of locking the locking member with the second through hole 61.
[0045] In this embodiment, the lining 23 is provided with a buckle 7, and the bottom plate 24 is provided with a positioning hole 71 corresponding to the buckle 7. A plurality of buckles 7 are provided and are evenly distributed at the bottom of the lining 23. The buckle 7 is obtained by extending downward from the lining 23, that is, the buckle 7 and the lining 23 are integrally formed, which is conducive to reducing the connection process between the buckle 7 and the lining 23. When installing the lining 23, the buckle 7 on the lining 23 extends into the corresponding positioning hole 71, which can limit the lining 23, so as to facilitate the positioning and assembly between the lining 23 and the bottom plate 24, thereby simplifying the assembly process and saving the time required for assembly.
[0046] In one possible implementation, columns 26 are provided on both sides of the front opening of the lining 23, and the columns 26 are connected to the lining 23 and the bottom plate 24 by locking members, so that the lining 23 has sufficient strength to ensure that it will not be deformed when falling, and at the same time can improve the connection stability between the lining 23 and the bottom plate 24.
[0047] In addition, the bottom plate 24 can be made of high temperature resistant metal material, such as stainless steel, etc. On the one hand, the high temperature resistance of the bottom plate 24 can be ensured, and the cost of metal materials is relatively low compared to the cost of high temperature resistant plastic parts, which is conducive to reducing the cost of cooking equipment; on the other hand, the surface of the metal material has the function of reflecting heat energy, that is, when the pot assembly 25 containing food is heated in the cavity surrounded by the lining 23 and the bottom plate 24, the upper surface of the bottom plate 24 can reflect the heat energy to avoid the heat energy loss in the cavity, thereby helping to improve the energy storage effect in the cavity and reduce the energy consumption of the cooking equipment.
[0048] In other embodiments, the lining 23 may also be made of high temperature resistant metal materials such as stainless steel, which can further enhance the energy storage effect in the cavity while ensuring the high temperature resistance of the lining 23 and the bottom plate 24, thereby facilitating the quality and reliability of the cooking equipment.
[0049] Embodiment 2:
[0050] The difference between this embodiment and the first embodiment is that the first connecting member 3 and the second connecting member 4 , the third connecting member 5 and the fourth connecting member 6 are not fixedly connected together by means of a locking member.
[0051] As an implementation manner, the first connecting member 3 and the second connecting member 4, and the third connecting member 5 and the fourth connecting member 6 can be fixedly connected together by welding or hot melting.
[0052] As another embodiment, the first connecting member 3 and the second connecting member 4, the third connecting member 5 and the fourth connecting member 6 can be directly fixed together by mutual snap-fitting. For example, the second connecting member 4 and the fourth connecting member 6 can be configured as card slots, and the first connecting member 3 and the third connecting member 5 can be configured as card blocks that can be inserted into the corresponding card slots. By inserting the card blocks into the card slots, the first connecting member 3 and the second connecting member 4, the third connecting member 5 and the fourth connecting member 6 can be fixedly connected together without the aid of locking members.
[0053] In other implementations, the specific structures of the first connecting member 3, the second connecting member 4, the third connecting member 5 and the fourth connecting member 6 can be set according to actual needs, so that the first connecting member 3 and the second connecting member 4, the third connecting member 5 and the fourth connecting member 6 can be fixedly connected together without the aid of a locking member, so that the bottom plate 24 can be firmly fixed between the lining 23 and the bottom shell 22, while simplifying the connection structure between the lining 23, the bottom plate 24 and the bottom shell 22 and reducing the number of parts, which is beneficial to simplify the assembly process of the cooking equipment and shorten the time required for assembly.
[0054] Embodiment 3:
[0055] The difference between this embodiment and the above embodiment is that: Figure 6 As shown, an air inlet 8 is provided at the bottom of the bottom shell 22, a gap is provided between the bottom shell 22 and the bottom plate 24 to form a first space 81, a gap is provided between the outer shell 21 and the lining 23 to form a second space 82 connected to the first space 81, and an air outlet connected to the outside air is provided on the outer shell 21.
[0056] The cold air from the outside enters the first space 81 through the air inlet 8, passes through the second space 82, and is finally discharged from the air outlet to achieve a complete cold air circulation; during the cold air circulation process, it can take away the heat from the bottom shell 22, reduce the temperature of the bottom shell 22, and improve the overall safety.
[0057] It should be noted that, in order to reduce the overall weight of the cooking device, the bottom shell 22 is made of plastic. The bottom air suction structure is adopted, so that the heat at the bottom shell 22 can be taken away from the air outlet through the first space 81 and the second space 82, thereby preventing the temperature at the bottom shell 22 from being too high and causing the plastic bottom shell 22 to melt, and also solving the problem of the metal material bottom plate 24 and the plastic bottom shell 22 directly contacting each other and causing the temperature at the connection to be too high.
[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
