Description

Technical Field

[0001] This application relates to the technical field of kitchen equipment, and in particular to a compact cooking device. Background Technology

[0002] Most existing grilling equipment has a hot air circulation component installed on the top of the container. The hot air circulation component includes a heating element, a fan blade, and a motor that drives the fan blade to rotate. The heating element generates heat, and the fan blade rotates under the drive of the motor, blowing the heat generated by the heating element into the container to heat the food.

[0003] To meet users' needs for cooking multiple different ingredients simultaneously, grilling equipment with two independent cooking cavities has emerged on the market. In this dual-cavity equipment, each of the upper and lower cooking cavities is equipped with a complete and independent hot air circulation component. That is, the top of the upper cavity has a set of motors, fan blades and heating elements, and the top of the lower cavity also has an identical set of components. This simple stacked design makes the cooking equipment occupy a large amount of height space, which is not conducive to users storing the cooking equipment. Utility Model Content

[0004] To effectively solve the above problems, this application provides a compact cooking device.

[0005] This application provides a compact cooking device, which adopts the following technical solution:

[0006] A compact cooking device includes a housing, two cooking chambers located inside the housing and distributed vertically, and a pot assembly located inside the cooking chamber. Each pot assembly is provided with a hot air circulation assembly, which includes a heating element, a first fan blade, and a drive motor for driving the first fan blade to rotate. The first fan blade and the heating element are both located above the pot assembly. A first space is provided between the rear side of the cooking chamber and the housing. At least one drive motor is offset within the first space and is provided with a belt drive structure between it and the first fan blade.

[0007] By adopting the above technical solution, at least one drive motor is offset within the first space, and the drive motor occupying vertical space is moved from directly above the cooking cavity to the first space behind the cooking cavity. The space occupied by the drive motor overlaps with the cooking cavity in the horizontal direction, rather than being vertically superimposed, thereby significantly reducing the overall height of the machine and greatly improving the storage convenience of the cooking equipment. Furthermore, the belt drive structure solves the problem that the drive motor and the first fan blade are not on the same straight line, realizing non-coaxial transmission, which forms the basis for the implementation of this solution.

[0008] Both the first fan blade and the heating element are located above the pot body components, allowing hot air to blow downwards. This follows the physical law of hot air rising naturally, which helps to create a uniform and efficient airflow within the pot, ensuring even heating of food and preventing localized overheating or staleness. Furthermore, each pot body component is equipped with a corresponding hot air circulation system. This means that the upper and lower chambers are completely independent temperature and ventilation systems. Users can simultaneously cook different ingredients at different temperatures and times in different cooking chambers (such as roasting meat on the upper chamber and baking desserts on the lower chamber) without worrying about flavor mixing or temperature cross-contamination, maximizing functionality.

[0009] Optionally, one of the drive motors is located above the pot body assembly, and the output shaft of the drive motor is connected to the first fan blade; the other drive component is located in the corresponding first space and is connected to the first fan blade through a belt drive structure.

[0010] By adopting the above technical solution, the strict vertical stacking relationship is directly broken by biasing one of the drive motors. Even if the other drive motor is still located above the pot assembly, the total height of the equipment is significantly reduced because the two drive motors are no longer perfectly aligned.

[0011] Optionally, both drive motors are located in the corresponding first space, and each drive motor is connected to the corresponding first fan blade through a belt drive structure.

[0012] By adopting the above technical solution, the two drive motors that occupy the largest vertical space are removed from directly above the cooking cavity. This allows the upper and lower cooking cavities and the heating element above them to be as close as possible to the first fan blade. Only the necessary airflow channels and structural thickness need to be reserved between them, and there is no need to reserve space for the axial height of any motor. This allows the overall height of the machine to be compressed to the limit, greatly improving the product's storage convenience and adaptability to kitchen space.

[0013] Optionally, the drive motor is located in any one of the first spaces, and both ends of the drive motor are provided with output shafts, which are connected to the two first fan blades through the pulley belt transmission structure provided at both ends.

[0014] By adopting the above technical solution, the two independent motors that must exist in the traditional design are completely eliminated by using a drive motor with output shafts at both ends, which can save space and cost; and the drive motor is placed in either of the first spaces, which means that there are no drive motors directly above the two cooking cavities, which can further reduce the overall height.

[0015] Optionally, the belt drive structure includes a driven wheel connected to the first fan blade, a driving wheel connected to the output shaft of the drive motor, and a belt connecting the driving wheel and the driven wheel.

[0016] Optionally, a cold air chamber communicating with the outside is provided inside the housing and on one side, and a second fan blade is provided inside the cold air chamber, with the output shaft of the drive motor connected to the second fan blade.

[0017] Optionally, the second fan blade is located between the drive wheel and the drive motor.

[0018] Optionally, the housing is further provided with an air outlet communicating with the outside, a hot air outlet communicating with the cooking cavity, and a cold air outlet communicating with the cold air cavity, and both the cold air outlet and the hot air outlet are connected to the air outlet.

[0025] Example 1:

[0026] This application discloses a compact cooking device, such as... Figure 1As shown, the device includes a housing 1, two cooking chambers 2 located inside the housing 1 and distributed vertically, and a pot assembly 3 located within the cooking chambers 2. The pot assembly 3 includes a pot body 31 and a protective plate 32 disposed on the front side of the pot body 31. A handle 33 is provided on the protective plate 32. An opening is provided on the front side of the housing 1, through which the pot body 31 extends into the cooking chamber 2, and the protective plate 32 covers and seals the opening. Each pot assembly 3 is correspondingly provided with a hot air circulation assembly 4. The hot air circulation assembly 4 includes a heating element 41, a first fan blade 42, and a drive motor 43 that drives the first fan blade 42 to rotate. The first fan blade 42 and the heating element 41 are both located above the pot assembly 31. A first space 5 is provided between the rear side of the cooking chamber 2 and the housing 1. At least one drive motor 43 is offset within the first space 5 and is provided with a belt drive structure 6 between itself and the first fan blade 42.

[0027] At least one drive motor 43 is offset within the first space 5, thereby moving the drive motor 43, which occupies vertical space, from directly above the cooking cavity 2 to the first space 5 behind the cooking cavity 2. This makes the space occupied by the drive motor 43 overlap with the cooking cavity 2 in the horizontal direction, rather than being vertically superimposed, thus significantly reducing the overall height of the machine and greatly improving the storage convenience of the cooking equipment. Furthermore, the problem that the drive motor 43 and the first fan blade 42 are not on the same straight line is solved by the belt drive structure 6, realizing non-coaxial transmission.

[0028] When at least one drive motor 43 is not located directly above the heating element 41, the heat from the heating element 41 is prevented from directly affecting the corresponding drive motor 43, thereby extending the service life of the drive motor 43.

[0029] Both the first fan blade 42 and the heating element 41 are located above the pot body assembly 3, allowing hot air to blow from top to bottom, conforming to the physical law of hot air rising naturally. This helps to form a uniform and efficient circulating airflow within the pot body 31, ensuring that the food is heated evenly and avoiding localized overheating or uncooking. Furthermore, each pot body assembly 3 is equipped with a corresponding hot air circulation component 4, which means that the upper and lower chambers are completely independent temperature control and ventilation systems. Users can simultaneously cook different ingredients at different temperatures and times in different cooking chambers 2 (such as roasting meat on the upper layer and baking desserts on the lower layer) without worrying about flavor mixing or temperature cross-interference, thus maximizing functionality.

[0030] It should be noted that both drive motors 43 are located in the corresponding first space 5. Each drive motor 43 is connected to the corresponding first fan blade 42 through the belt drive structure 6. The two drive motors 43, which occupy the largest vertical space, are removed from directly above the cooking cavity 2. This allows the upper and lower cooking cavities 2 and the heating element 41 above them to be as close as possible to the first fan blade 42. Only the necessary airflow channels and structural thickness need to be reserved between them, and there is no need to reserve space for the axial height of any motor. This allows the overall height of the machine to be compressed to the limit, greatly improving the product's storage convenience and adaptability to kitchen space.

[0031] The belt drive structure 6 includes a driven wheel 61 connected to the first fan blade 42, a driving wheel 62 connected to the output shaft of the drive motor 43, and a belt 63 connecting the driving wheel 62 and the driven wheel 61. When the drive motor 43 rotates, it drives the driving wheel 62 to rotate. The driving wheel 62, through the belt 63, drives the driven wheel 61 to rotate, which in turn drives the first fan blade 42 to rotate. This facilitates the blowing of heat generated by the heating element 41 into the corresponding cooking cavity 2, heating the food inside the cooking cavity 2.

[0032] In this embodiment, a reflector corresponding to the cooking cavity 2 is provided inside the housing 1, and an accommodating space is formed between the upper part of the reflector and the housing 1. The heating element 41 and the first fan blade 42 are located inside the reflector, and the belt drive structure 6 is located inside the accommodating space.

[0033] Furthermore, a cold air chamber 7, communicating with the receiving space, is provided inside the housing 1 on one side. A second fan blade 71 is provided inside the cold air chamber 7, and the output shaft of the drive motor 43 is connected to the second fan blade 71. The second fan blade 71 is located between the drive wheel 62 and the drive motor 43. An air inlet is provided on the side of the housing 1 away from the drive motor 43, and the air inlet communicates with the receiving space. When the drive motor 43 drives the second fan blade 71 to rotate, cold air from the outside enters the receiving space and the cold air chamber 7 through the air inlet, cooling the driven wheel 61, belt 63, and drive wheel 62, thereby improving the service life of the belt drive structure 6.

[0034] The housing 1 also includes an air outlet 72 communicating with the outside, a hot air outlet 74 communicating with the cooking cavity 2, and a cold air outlet 73 communicating with the cold air cavity 7. Both the cold air outlet 73 and the hot air outlet 74 are connected to the air outlet 72. By converging the cold air outlet 73 and the hot air outlet 74 into a single air outlet 72, the temperature at the air outlet 72 can be reduced, lowering the risk of burns to the user. Furthermore, it reduces the need for a separate opening on the housing 1, improving the overall aesthetics.

[0035] Its drive motor 43 is located behind the hot air outlet 74, which neither affects the flow of hot air nor hinders the normal operation of the equipment.

[0036] Example 2:

[0037] The difference between this embodiment and the above embodiments is that: Figure 2 As shown, one drive motor 43 is located above the pot body 31 assembly 3, and the output shaft of the drive motor 43 is connected to the first fan blade 42; the other drive motor 43 is located in the corresponding first space 5 and is connected to the first fan blade 42 through the belt drive structure 6. By offsetting one of the drive motors 43, this strict vertical stacking relationship is directly broken. Even though the other drive motor 43 is still located above the pot body 31 assembly 3, the overall height of the device is significantly reduced because the two drive motors 43 are no longer perfectly aligned.

[0038] Example 3:

[0039] The difference between this embodiment and the above embodiments is that: Figure 3 As shown, the drive motor 43 is located within either of the first spaces 5. Both ends of the drive motor 43 have output shafts, which are connected to the two first fan blades 42 via belt drive structures 6 at both ends. By using a single drive motor 43 with output shafts at both ends, the need for two separate motors in traditional designs is completely eliminated, saving space and cost. Furthermore, since the drive motor 43 is placed within either of the first spaces 5, there are no drive motors 43 directly above the two cooking cavities 2, further reducing the overall height.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
