[0040] The cooking equipment 100 according to the embodiments of the present application is described below with reference to FIGS. 1-7.

[0041] With reference to FIG. 1, FIG. 2 and FIG. 3, the cooking device 100 according to the embodiments of the present application comprises: an inner container 1, an air duct assembly 2 and a guide fan 3. The inner container 1 is provided with a cooking cavity 11, and the inner container 1 is further provided with a first exhaust port 111 and a second exhaust port 112 which are in communication with the cooking cavity 11; the air duct assembly 2 is provided with an air flow passage 21 located outside the cooking cavity 11, and the air flow passage 21 is provided with an air outlet 211 which is in communication with the outside of the inner container 1, and the first exhaust port 111 and the second exhaust port 112 are both in communication with the air flow passage 21; at least part of the guide fan 3 is arranged in the air flow passage 21 for guiding the air flow towards the air outlet 211, and the first exhaust port 111 and the second exhaust port 112 are distributed on both sides of the guide fan 3.

[0042] When the guide fan 3 is working, the air flow is guided to flow so that the exhaust gas in the cooking cavity 11 enters the air flow passage 21 through the first exhaust port 111 and the second exhaust port 112, and then is discharged through the air outlet 211.

[0043] According to the cooking device 100 of the embodiments of the present application, the exhaust is realized through the first exhaust port 111 and the second exhaust port 112, which improves the exhaust efficiency of the cooking cavity 11, and the first exhaust port 111 and the second exhaust port 112 are distributed on both sides of the guide fan 3, so that the first exhaust port 111 and the second exhaust port 112 can be used to absorb the exhaust gas at different positions in the cooking cavity 11, which is beneficial to balance the air pressure inside the cooking cavity 11 and realize the function of uniform exhaust.

[0044] In some embodiments, the first exhaust port 111 and the second exhaust port 112 are symmetrically distributed on both sides of the guide fan 3, so that the first exhaust port 111 and the second exhaust port 112 are more appropriately arranged in the cooking cavity 11, and the symmetrical design can fully and completely absorb the exhaust gas in the cooking cavity 11, avoiding the dead angle where the exhaust gas cannot be absorbed, further improving the exhaust efficiency of the cooking cavity 11 and ensuring the cooking effect of the cooking device 100.

[0045] In some specific embodiments, the first exhaust port 111 and the second exhaust port 112 are symmetrically distributed on both sides of the guide fan 3, and the first exhaust port 111 and the second exhaust port 112 are arranged along the front-rear direction of the cooking device 100.

[0046] In some specific embodiments, the first exhaust port 111 and the second exhaust port 112 are symmetrically distributed on both sides of the guide fan 3, and the first exhaust port 111 and the second exhaust port 112 are arranged along the front-rear direction of the cooking device 100.

[0047] In other embodiments, the first exhaust port 111 and the second exhaust port 112 are symmetrically distributed on both sides of the guide fan 3, and the first exhaust port 111 and the second exhaust port 112 can also be arranged at other angles in the horizontal direction. As long as the first exhaust port 111 and the second exhaust port 112 are symmetrically distributed on both sides of the guide fan 3.

[0048] In some embodiments, the cooking device 100 further comprises a cabinet, the inner container 1 is arranged in the cabinet, and the air duct assembly 2 is further provided with an air inlet 212 in communication with the airflow channel 21, the air inlet 212 being located between the inner container 1 and the cabinet, and the air outlet 211 being in communication with the outside of the cabinet.

[0049] When the guide fan 3 is working, the air between the inner container 1 and the cabinet is sucked into the airflow channel 21 through the air inlet 212, and then discharged to the outside of the cabinet through the air outlet 211.

[0050] The space between the cabinet and the inner container 1 is provided with components such as a control module and a power module. In the embodiment of the present application, the guide fan 3 continuously absorbs the air between the inner container 1 and the cabinet, accelerates the flow rate of the air between the inner container 1 and the cabinet, improves the heat dissipation efficiency of the components between the inner container 1 and the cabinet, reduces the risk of damage to the cooking device 100, and prolongs the service life of the cooking device 100.

[0051] In the embodiment of the present application, the airflow channel 21 can not only be used to discharge the exhaust gas in the cooking cavity 11, but also be used for heat dissipation of the cooking device 100, without the need to design a special air duct for heat dissipation, thereby simplifying the structure of the cooking device 100 and reducing the cost of the cooking device 100.

[0052] Referring to FIGS. 2, 3 and 5, in some embodiments, the cooking device 100 further comprises a first smoke exhaust pipe 5, one end of the first smoke exhaust pipe 5 being in communication with the first exhaust port 111, and the other end being in communication with the airflow channel 21.

[0053] Through the above technical solution, the first smoke exhaust pipe 5 guides the exhaust gas in the cooking cavity 11 into the airflow channel 21, so that the exhaust gas passing through the first exhaust port 111 can smoothly enter the airflow channel 21, instead of staying in the space between the cabinet and the inner container 1, thereby avoiding pollution of the components between the cabinet and the inner container 1 by the exhaust gas and ensuring the reliability of the cooking device 100. In addition, the first smoke exhaust pipe 5 can also concentrate the suction force generated by the airflow channel 21 at the first exhaust port 111, thereby increasing the exhaust rate of the first exhaust port 111 and improving the exhaust efficiency of the cooking cavity 11.

[0054] In some specific embodiments, the end of the first smoke exhaust pipe 5 away from the first exhaust port 111 and the air inlet 212 are located on the same side of the guide fan 3.

[0055] That is, the first exhaust port 111 is communicated with the air inlet side of the guide fan 3 through the first flue, and when the guide fan 3 is working, the air inlet side of the guide fan 3 generates negative pressure to guide the air at the air inlet side to the air outlet side, thereby generating suction at the air inlet and the first exhaust port 111, the air between the cabinet and the inner container 1 enters the airflow channel 21 through the air inlet 212, and then flows towards the air outlet 211 after passing through the guide fan 3 to be discharged from the cooking equipment 100, and the exhaust gas in the cooking cavity 11 enters the airflow channel 21 through the first exhaust port 111 and the first flue 5, and then flows towards the air outlet 211 after passing through the guide fan 3 to be discharged from the cooking equipment 100.

[0056] In the embodiments of the present application, by communicating the first exhaust port 111 with the air inlet side of the guide fan 3, the suction at the first exhaust port 111 is ensured, that is, the reliability of the smoke exhaust of the first exhaust port 111 is ensured.

[0057] Referring to FIGS. 2, 3 and 5, in some embodiments, the first flue 5 includes a first portion 51 and a second portion 52 forming an included angle, the first end of the first portion 51 is communicated with the first exhaust port 111 and the second end is connected with the second portion 52, and the smoke exhaust end of the second portion 52 is suspended and arranged opposite to the air inlet 212.

[0058] The exhaust gas of the cooking cavity 11 enters the first portion 51 after passing through the first exhaust port 111, then passes through the smoke exhaust end of the second portion 52, enters the airflow channel 21 through the air inlet 212, and is discharged from the cooking equipment 100 through the air outlet 211.

[0059] In the embodiments of the present application, the smoke exhaust end of the second portion 52 is suspended and arranged opposite to the air inlet 212, without the need for physically connecting the smoke exhaust end of the second portion 52 with the air duct assembly 2, thereby improving the installation efficiency of the first flue 5 and reducing the cost of the cooking equipment 100.

[0060] Moreover, the design in the embodiments of the present application reduces the opening of the airflow channel 21 at the air inlet side of the guide fan 3, improves the suction at the air inlet, and ensures the stability of the gas flow in the airflow channel 21.

[0061] In some further embodiments, the first portion 51 and the second portion 52 are connected in a circular arc transition, which improves the smoothness of the gas in the first portion 51 entering the second portion 52, and further improves the exhaust efficiency of the cooking cavity 11.

[0062] In some specific embodiments, a part of the second portion 52 is bent towards the air inlet 212 to define a smoke exhaust end with an opening downward. The smoke exhaust end of the second portion 52 is arranged downward, so that the flue gas discharged from the second portion 52 can directly flow to the air inlet, thereby reducing the risk of the flue gas discharged from the second portion 52 accumulating between the cabinet and the inner container 1.

[0063] Referring to FIGS. 2, 3 and 5, in some embodiments, an end of the first smoke exhaust pipe 5 close to the first exhaust port 111 is provided with a first mounting portion 53, and the first mounting portion 53 is mounted to the inner container 1.

[0064] In the embodiments of the present application, the first smoke exhaust pipe 5 is fixed to the inner container 1 through the first mounting portion 53, which ensures the stability of the communication between the first smoke exhaust pipe 5 and the first exhaust port 111, so that the cooking cavity 11 can stably exhaust, and the stability of the exhaust of the first exhaust port 111 is ensured.

[0065] In some embodiments, the first mounting portion 53 is abutted with a part of the inner container 1, the first mounting portion 53 is provided with a mounting hole 531, and the first mounting portion 53 is fixed to the inner container 1 by a fastener passing through the mounting hole 531, and the fastener is configured as a screw or a bolt.

[0066] In the embodiments of the present application, the connection mode of the fastener and the first mounting portion 53 and the inner container 1 is simple, which improves the installation efficiency of the first smoke exhaust pipe 5, and the connection stability of the first mounting portion 53 and the inner container 1 is high, which ensures the reliability of the use of the first smoke exhaust pipe 5.

[0067] Referring to FIGS. 2, 3 and 5, in some embodiments, the inner container 1 includes a back plate 12, the back plate 12 participates in defining the above-mentioned cooking cavity 11, a part of the back plate 12 extends towards a direction away from the cooking cavity 11, and the first mounting portion 53 is connected with the part of the back plate 12 away from the cooking cavity 11.

[0068] Through the above technical solution, on the one hand, the installation of the first mounting portion 53 does not affect the cooking cavity 11, and a through hole for communicating with the cooking cavity 11 does not need to be provided on the inner container 1 for the installation of the first mounting portion 53; on the other hand, the convenience of the installation of the first mounting portion 53 and the inner container 1 is improved.

[0069] Referring to FIGS. 2, 3 and 4, in some embodiments, the cooking device 100 further includes a second smoke exhaust pipe 6, one end of the second smoke exhaust pipe 6 is communicated with the second exhaust port 112, and the other end of the second smoke exhaust pipe 6 and the air outlet 211 are located on the same side of the guide fan 3.

[0070] When the guide fan 3 is working, the guide fan 3 drives the gas flow in the airflow channel 21 to the air outlet 211. According to Bernoulli's law, the faster the flow rate in the gas flow, the smaller the pressure generated by the fluid. Because the flow rate of the airflow on the air outlet side of the airflow channel 21 is greater than the flow rate of the airflow in the second exhaust pipe 6, the air pressure on the air outlet side of the airflow channel 21 is lower than the air pressure in the second exhaust pipe 6. Thus, the gas in the second exhaust pipe 6 flows to the airflow channel 21, and the gas in the second exhaust pipe 6 flows to the airflow channel 21 to generate negative pressure at the second exhaust port 112 of the second exhaust pipe 6, thereby continuously sucking the gas in the cooking cavity 11 into the second exhaust pipe 6.

[0071] Through the above technical solution, the gas in the cooking cavity 11 can continuously enter the airflow channel 21 through the second exhaust port 112 and the second exhaust pipe, and finally be discharged from the cooking device 100 through the air outlet 211, thereby ensuring the reliability of the exhaust of the second exhaust port 112.

[0072] Furthermore, the first exhaust port 111 is in communication with the air inlet side of the guide fan 3, and the second exhaust port 112 is in communication with the air outlet side of the guide fan 3. The air pressure on both sides of the guide fan 3 is fully utilized, and the exhaust efficiency of the cooking device 100 is improved. Compared with the technical solution in which multiple exhaust ports are in communication with the air inlet side of the guide fan 3, the design of the present application reduces the energy efficiency of the guide fan 3, which is conducive to the energy-saving design of the cooking device 100.

[0073] Referring to FIGS. 3 and 7, in some further embodiments, the airflow channel 21 is provided with a shielding part 22, which is arranged on the side of the second exhaust pipe 6 facing the guide fan 3. The shielding part 22 is used to shield the airflow in the airflow channel 21 from flowing to the second exhaust pipe 6.

[0074] In the present application, the shielding part 22 blocks the airflow in the airflow channel 21 from flowing to the second exhaust pipe 6, thereby preventing the airflow in the airflow channel 21 from entering the second exhaust pipe 6 and affecting the exhaust of the cooking cavity 11, and ensuring the stability of the exhaust of the second exhaust port 112.

[0075] In some specific embodiments, a part of the air duct assembly 2 is separated from the other part and is bent towards the inside of the airflow channel 21 to define the shielding part 22 and an opening in communication with the second exhaust pipe 6, respectively.

[0076] In the present application, the shielding part has a simple structure and is integrally formed with the inner wall of the airflow channel 21, thereby reducing the step of mounting the shielding part on the inner wall of the airflow channel 21, improving the processing efficiency of the air duct assembly 2, and reducing the production cost of the cooking device 100. Furthermore, the opening for communicating with the second exhaust pipe 6 is naturally formed during the processing of the shielding part, further improving the processing efficiency of the air duct assembly 2 and reducing the cost of the cooking device 100.

[0077] Referring to FIGS. 3 and 6, in some embodiments, at least a portion of the cross section of the second smoke pipe 6 gradually increases in the direction towards the second exhaust port 112.

[0078] That is, in the direction towards the airflow passage 21, at least a portion of the cross section of the second smoke pipe 6 gradually decreases, thereby reducing the opening of the second smoke pipe 6 communicating with the airflow passage 21, thereby increasing the suction of the second smoke pipe 6, so that the gas in the cooking cavity 11 can easily enter the airflow passage 21, further improving the exhaust efficiency of the second exhaust port 112.

[0079] Referring to FIGS. 3, 4 and 6, in some embodiments, the second smoke pipe 6 is provided with spaced apart positioning portions 61 and fixing portions 62, the positioning portions 61 are insertedly fitted with the inner container 1, and the fixing portions 62 are positioned with the inner container 1.

[0080] In the embodiments of the present application, the positioning portions 61 are insertedly fitted with the inner container 1, improving the stability of the connection of the second smoke pipe 6 with the inner container 1, and the fixing portions 62 are positioned with the inner container 1, further improving the stability of the connection of the second smoke pipe 6 with the inner container 1. The cooperation of the positioning portions 61 and the fixing portions 62 stably installs the second smoke pipe 6 on the inner container 1, ensuring the reliability of the exhaust of the second exhaust port 112.

[0081] Referring to FIGS. 3, 4 and 6, in some specific embodiments, the inner container 1 is provided with mounting grooves 113 and fixing holes 114, the mounting grooves 113 and the fixing holes 114 are distributed on both sides of the second exhaust port 112, the positioning portions 61 are inserted into the mounting grooves 113, the positioning portions 61 are opposite to the fixing holes 114, and fasteners pass through the fixing holes 114 to be fixed with the positioning portions 61, thereby installing the second smoke pipe 6 on the inner container 1.

[0082] In the embodiments of the present application, the installation mode of the second smoke pipe 6 is simple, improving the installation efficiency of the second smoke pipe 6 and reducing the cost of the cooking equipment 100.

[0083] Referring to FIGS. 3 and 7, in some embodiments, the air duct assembly 2 comprises: a first air guide 23 and a second air guide 24, the second air guide 24 is arranged on the upper side of the inner container 1, and the first air guide 23 is arranged on the upper side of the second air guide 24 and defines the airflow passage 21 between the second air guide 24.

[0084] The air inlet 212 is arranged on the top wall of the first air guide 23, and the first air guide 23 and the second air guide 24 both extend towards the front wall of the cabinet and form the air outlet 211 arranged towards the front wall of the cabinet, and the air outlet 211 communicates with the through hole on the front wall of the cabinet.

[0085] The guide fan 3 comprises a driving motor and a fan blade 31. The driving motor is arranged on the upper side of the first air guide 23, and the fan blade 31 is arranged in the airflow channel 21. The output shaft of the driving motor penetrates the air inlet and is connected with the fan blade 31 to drive the fan blade 31 to rotate.

[0086] The first exhaust port 111 and the second exhaust port 112 are arranged on the top wall of the inner container 1 and are symmetrically distributed on both sides of the fan blade 31. The first exhaust port 111 is communicated with the air inlet side of the fan blade 31 through the first flue 5, and the second exhaust port 112 is communicated with the air outlet side of the fan blade 31 through the second flue 6.

[0087] When the cooking device 100 works, some exhaust gas in the cooking cavity 11 needs to be discharged due to the expansion of gas and the evaporation of liquid in the cooking cavity 11. The driving motor drives the fan blade 31 to rotate, so that the air inlet side of the fan blade 31 generates negative pressure. Part of the exhaust gas in the cooking cavity 11 enters the airflow channel 21 through the first exhaust port 111 and the first flue 5, and finally is discharged from the cooking space through the air outlet 211. When the fan blade 31 rotates, the airflow is driven to flow through the flue outlet of the second flue 6, so that the second flue 6 generates negative pressure. Another part of the exhaust gas in the cooking cavity 11 enters the airflow channel 21 through the second flue 6, and finally is discharged from the cooking space through the air outlet 211. When the fan blade 31 rotates, the air between the cabinet and the inner container 1 is also sucked into the airflow channel 21 through the air inlet, and finally is discharged from the cooking space through the air outlet 211.

[0088] In the embodiment of the present application, the air duct assembly 2 is arranged on the upper side of the inner container 1, and the first exhaust port 111 and the second exhaust port 112 are arranged on the top wall of the inner container 1, which conforms to the characteristic that the exhaust gas is easy to flow upward, and further improves the efficiency of discharging the exhaust gas in the cooking cavity 11.

[0089] It should be noted that the airflow channel 21 can be a channel independently defined by the air duct assembly 2, or a channel jointly defined by the air duct assembly 2 and the outer wall of the inner container 1, as long as a channel for airflow to flow can be formed, which is not limited in the present application.

[0090] Referring to FIGS. 1, 2 and 3, in some embodiments, the cooking device 100 further comprises a burner assembly 7 arranged in the cooking cavity 11 to heat the cooking cavity 11.

[0091] The cooking device 100 of the embodiment of the present application can grill food through the burner assembly 7, thereby improving the cooking effect of the cooking device 100.

[0092] When the burner assembly 7 is in operation, the combustible gas is combusted in the burner assembly 7, and heat generated by the combustion is used to grill the food. During the combustion of the combustible gas, smoke is easily generated. If the smoke cannot be discharged in time, the smoke will squeeze the oxygen in the cooking cavity 11, causing insufficient oxygen and insufficient combustion of the combustible gas, which affects the cooking effect of the cooking device 100.

[0093] In the embodiments of the present application, the cooking cavity 11 is provided with a first exhaust port 111 and a second exhaust port 112.
