[0037] Reference below Figure 1-Figure 7 A cooking device 100 according to an embodiment of the present invention is described.

[0038] Reference Figure 1 、 Figure 2 and Figure 3 According to an embodiment of the present invention, a cooking device 100 includes an inner pot 1, an air duct assembly 2, and a guide fan 3. The inner pot 1 is provided with a cooking cavity 11, which is further provided with a first exhaust port 111 and a second exhaust port 112 communicating with the cooking cavity 11. The air duct assembly 2 is provided with an air flow channel 21 located outside the cooking cavity 11. The air flow channel 21 is provided with an air outlet 211 communicating with the outside of the inner pot 1. The first exhaust port 111 and the second exhaust port 112 are both connected to the air flow channel 21. The guide fan 3 is at least partially disposed within the air flow channel 21 to guide airflow toward the air outlet 211. The first exhaust port 111 and the second exhaust port 112 are distributed on both sides of the guide fan 3.

[0039] When the guide fan 3 is working, it guides the air flow so that the exhaust gas in the cooking cavity 11 enters the air flow channel 21 through the first exhaust port 111 and the second exhaust port 112 and is then discharged through the air outlet 211 .

[0040] According to the cooking device 100 of the embodiment of the present invention, exhaust is jointly performed through the first exhaust port 111 and the second exhaust port 112, thereby improving 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 exhaust gas from different positions in the cooking cavity 11, which is beneficial to balancing the air pressure inside the cooking cavity 11 and realizing the function of uniform exhaust.

[0041] 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 arrangement of the first exhaust port 111 and the second exhaust port 112 in the cooking cavity 11 is more appropriate. The symmetrical design can fully and completely absorb the exhaust gas in the cooking cavity 11, avoiding dead corners where the exhaust gas cannot be absorbed, further improving the efficiency of the cooking cavity 11 in discharging exhaust gas, and ensuring the cooking effect of the cooking device 100.

[0042] In some specific embodiments, the first exhaust port 111 and the second exhaust port 112 are symmetrically distributed on both sides of the induced fan 3 , and the first exhaust port 111 and the second exhaust port 112 are arranged along the front-to-back direction of the cooking device 100 .

[0043] In other specific embodiments, the first exhaust port 111 and the second exhaust port 112 are symmetrically distributed on both sides of the induced fan 3 , and the first exhaust port 111 and the second exhaust port 112 are arranged along the left-right direction of the cooking device 100 .

[0044] In other embodiments, the first exhaust port 111 and the second exhaust port 112 are symmetrically distributed on both sides of the induced draft fan 3. 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 induced draft fan 3, it will be sufficient.

[0045] In some embodiments, the cooking device 100 also includes a box body, the inner pot 1 is arranged in the box body, and the air duct assembly 2 is also provided with an air inlet 212 connected to the air flow channel 21. The air inlet 212 is located between the inner pot 1 and the box body, and the air outlet 211 is connected to the outside of the box body.

[0046] When the guide fan 3 is working, the air between the inner liner 1 and the box body is sucked into the air flow channel 21 through the air inlet 212, and then discharged to the outside of the box body through the air outlet 211.

[0047] Components such as a control module and a power module are arranged in the space between the box body and the inner pot 1. In an embodiment of the utility model, the air between the inner pot 1 and the box body is continuously absorbed by the guide fan 3, thereby accelerating the flow rate of the air between the inner pot 1 and the box body, improving the heat dissipation efficiency of the components between the inner pot 1 and the box body, reducing the risk of damage to the cooking device 100, and extending the service life of the cooking device 100.

[0048] In the embodiment of the present invention, the air flow channel 21 can not only be used to discharge the exhaust gas in the cooking cavity 11, but also be used to dissipate heat from the cooking device 100. There is no need to design a special air duct for heat dissipation, which simplifies the structure of the cooking device 100 and reduces the cost of the cooking device 100.

[0049] Reference Figure 2 、 Figure 3 and Figure 5 In some embodiments, the cooking device 100 further includes a first smoke exhaust pipe 5 , one end of which is connected to the first exhaust port 111 , and the other end of which is connected to the air flow channel 21 .

[0050] Through the above technical solution, the exhaust gas within the cooking cavity 11 is guided into the airflow channel 21 via the first exhaust pipe 5. This allows the exhaust gas passing through the first exhaust port 111 to smoothly enter the airflow channel 21, rather than stagnating in the space between the housing and the inner pot 1. This prevents the exhaust gas from contaminating the components between the housing and the inner pot 1, thus ensuring the reliability of the cooking device 100. Furthermore, the first exhaust pipe 5 can also converge the suction force generated by the airflow channel 21 at the first exhaust port 111, increasing the exhaust rate of the first exhaust port 111 and improving the exhaust efficiency of the cooking cavity 11.

[0051] 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 induced draft fan 3 .

[0052] That is to say, the first exhaust port 111 is connected to the air inlet side of the guide fan 3 through the first smoke exhaust pipe. When the guide fan 3 is working, the air inlet side of the guide fan 3 generates negative pressure to guide the air on the air inlet side toward the air outlet side, thereby generating suction at the air inlet and the first exhaust port 111. The air between the box body and the inner tank 1 enters the air flow channel 21 through the air inlet 212, and then flows toward the air outlet 211 after passing through the guide fan 3 to be discharged from the cooking equipment 100. The exhaust gas in the cooking cavity 11 enters the air flow channel 21 through the first exhaust port 111 and the first smoke exhaust pipe 5, and then flows toward the air outlet 211 after passing through the guide fan 3 to be discharged from the cooking equipment 100.

[0053] In the embodiment of the present invention, by connecting the first exhaust port 111 with the air inlet side of the induced draft fan 3 , the suction force at the first exhaust port 111 is ensured, that is, the reliability of smoke exhaust from the first exhaust port 111 is ensured.

[0054] Reference Figure 2 、 Figure 3 and Figure 5 In some embodiments, the first smoke exhaust pipe 5 includes a first part 51 and a second part 52 forming an angle, the first end of the first part 51 is connected to the first exhaust port 111 and the second end is connected to the second part 52, and the smoke exhaust end of the second part 52 is suspended and arranged opposite to the air inlet 212.

[0055] The exhaust gas from the cooking cavity 11 enters the first part 51 through the first exhaust port 111 , then passes through the exhaust end of the second part 52 , enters the air flow channel 21 through the air inlet 212 , and is then discharged from the cooking device 100 through the air outlet 211 .

[0056] In the embodiment of the utility model, the smoke exhaust end of the second part 52 is suspended and arranged opposite to the air inlet 212. There is no need to physically connect the smoke exhaust end of the second part 52 with the air duct assembly 2, which improves the installation efficiency of the first smoke exhaust pipe 5 and reduces the cost of the cooking equipment 100.

[0057] Furthermore, the design in the embodiment of the present invention reduces the opening of the air flow channel 21 on the air inlet side of the guide fan 3 , thereby increasing the suction force at the air inlet and ensuring the stability of the gas flow in the air flow channel 21 .

[0058] In some further embodiments, the first portion 51 and the second portion 52 are connected in an 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.

[0059] In some embodiments, a portion of the second portion 52 is bent toward the air inlet 212 to define a downwardly facing smoke exhaust end. The downwardly facing smoke exhaust end of the second portion 52 allows smoke exhausted from the second portion 52 to flow directly toward the air inlet, reducing the risk of smoke exhausted from the second portion 52 accumulating between the box body and the inner container 1.

[0060] Reference Figure 2 、 Figure 3 and Figure 5 In some specific embodiments, a first mounting portion 53 is provided at one end of the first smoke exhaust pipe 5 close to the first exhaust port 111 , and the first mounting portion 53 is mounted to the inner container 1 .

[0061] In the embodiment of the utility model, the first smoke exhaust pipe 5 is fixed to the inner pot 1 through the first mounting portion 53, ensuring the stability of the connection between the first smoke exhaust pipe 5 and the first exhaust port 111, so that the cooking cavity 11 can be exhausted stably, ensuring the stability of exhaust from the first exhaust port 111.

[0062] In some specific embodiments, the first mounting portion 53 abuts against a portion of the inner liner 1 , and the first mounting portion 53 is provided with a mounting hole 531 . The first mounting portion 53 is fixed to the inner liner 1 by fasteners passing through the mounting hole 531 , and the fasteners are configured as screws or bolts.

[0063] In the embodiment of the present invention, the connection method between the first mounting portion 53 of the fastener and the inner liner 1 is simple, which improves the installation efficiency of the first smoke exhaust pipe 5, and the connection stability between the first mounting portion 53 and the inner liner 1 is high, ensuring the reliability of the use of the first smoke exhaust pipe 5.

[0064] Reference Figure 2 、 Figure 3 and Figure 5 In some specific embodiments, the inner pot 1 includes a rear plate 12, which participates in defining the above-mentioned cooking cavity 11. A portion of the rear plate 12 extends in a direction away from the cooking cavity 11, and the first mounting portion 53 is connected to the portion of the rear plate 12 away from the cooking cavity 11.

[0065] Through the above technical solution, on the one hand, the installation of the first mounting portion 53 is avoided from affecting the cooking cavity 11, and there is no need to set a through hole connected to the cooking cavity 11 on the inner pot 1 in order to install the first mounting portion 53; on the other hand, the convenience of installing the first mounting portion 53 and the inner pot 1 is improved.

[0066] Reference Figure 2 、 Figure 3 and Figure 4 In some embodiments, the cooking device 100 further includes a second smoke exhaust pipe 6 , one end of which is connected to 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 induced draft fan 3 .

[0067] When the guide fan 3 is working, the guide fan 3 drives the gas in the airflow channel 21 to flow toward the air outlet 211. According to Bernoulli's principle, in the airflow, the faster the flow rate, the smaller the pressure generated by the fluid. Because the airflow rate on the air outlet side of the airflow channel 21 is greater than the airflow rate in the second smoke 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 smoke exhaust pipe 6, so that the gas in the second smoke exhaust pipe 6 flows to the airflow channel 21. The gas in the second smoke exhaust pipe 6 flows to the airflow channel 21, so that the second smoke exhaust pipe 6 generates a negative pressure at the second exhaust port 112, thereby continuously sucking the gas in the cooking cavity 11 into the second smoke exhaust pipe 6.

[0068] Through the above technical solution, the gas in the cooking cavity 11 can continuously enter the air flow channel 21 through the second exhaust port 112 and the second smoke exhaust, and finally be discharged from the cooking device 100 through the outlet 211, ensuring the reliability of the exhaust of the second exhaust port 112.

[0069] Furthermore, the first exhaust port 111 is connected to the air inlet side of the induced draft fan 3, and the second exhaust port 112 is connected to the air outlet side of the induced draft fan 3. This fully utilizes the air pressure on both sides of the induced draft fan 3 and improves the smoke exhaust efficiency of the cooking device 100. Compared to a technical solution in which multiple exhaust ports are connected to the air inlet side of the induced draft fan 3, the design of this embodiment of the utility model reduces the energy efficiency of the induced draft fan 3, thereby facilitating an energy-saving design of the cooking device 100.

[0070] Reference Figure 3 and Figure 7 In some further embodiments, a shielding portion 22 is provided in the airflow channel 21, and the shielding portion 22 is provided on the side of the second smoke exhaust pipe 6 facing the induced draft fan 3, and the shielding portion 22 is used to block the airflow in the airflow channel 21 from flowing toward the second smoke exhaust pipe 6.

[0071] In the embodiment of the utility model, the shielding portion 22 blocks the airflow in the airflow channel 21 from flowing toward the second smoke exhaust pipe 6, thereby preventing the airflow in the airflow channel 21 from entering the second smoke exhaust pipe 6 and affecting the exhaust of the cooking cavity 11, thereby ensuring the stability of the exhaust of the second exhaust port 112.

[0072] In some specific embodiments, a portion of the air duct assembly 2 is separated from other portions and bent toward the inside of the air flow channel 21 to define a shielding portion 22 and an opening communicating with the second smoke exhaust pipe 6 .

[0073] In this embodiment of the utility model, the shielding member has a simple structure and is integrally formed with the inner wall of the airflow channel 21. This reduces the number of steps required to install the shielding member on the inner wall of the airflow channel 21, improves the manufacturing efficiency of the air duct assembly 2, and reduces the production cost of the cooking device 100. Furthermore, the opening for communication with the second smoke exhaust pipe 6 is naturally formed during the manufacturing process of the shielding member, further improving the manufacturing efficiency of the air duct assembly 2 and reducing the cost of the cooking device 100.

[0074] Reference Figure 3 and Figure 6 In some embodiments, at least a portion of the cross-section of the second smoke exhaust pipe 6 gradually increases in the direction toward the second exhaust port 112 .

[0075] That is to say, in the direction toward the air flow channel 21, at least part of the cross-section of the second smoke exhaust pipe 6 gradually shrinks, thereby reducing the opening connecting the second smoke exhaust pipe 6 and the air flow channel 21, thereby increasing the suction force of the second smoke exhaust pipe 6, so that the gas in the cooking cavity 11 can easily enter the air flow channel 21, further improving the exhaust efficiency of the second exhaust port 112.

[0076] Reference Figure 3 、 Figure 4 and Figure 6 In some embodiments, the second smoke exhaust pipe 6 is provided with a positioning portion 61 and a fixing portion 62 that are spaced apart. The positioning portion 61 is plugged into the inner liner 1 , and the fixing portion 62 is positioned and matched with the inner liner 1 .

[0077] In the embodiment of the present invention, the positioning portion 61 is plugged into the inner liner 1, which improves the stability of the connection between the second smoke exhaust pipe 6 and the inner liner 1. The fixing portion 62 is positioned and matched with the inner liner 1, which further improves the stability of the connection between the second smoke exhaust pipe 6 and the inner liner 1. The positioning portion 61 and the fixing portion 62 cooperate to stably install the second smoke exhaust pipe 6 on the inner liner 1, thereby ensuring the reliability of exhaust from the second exhaust port 112.

[0078] Reference Figure 3 、 Figure 4 and Figure 6 In some specific embodiments, the inner liner 1 is provided with a mounting groove 113 and a fixing hole 114, which are distributed on both sides of the second exhaust port 112. The positioning portion 61 is inserted into the mounting groove 113, and the positioning portion 61 is opposite to the fixing hole 114. The fastener passes through the fixing hole 114 to be fixed to the positioning portion 61, thereby installing the second smoke exhaust pipe 6 on the inner liner 1.

[0079] In the embodiment of the present invention, the second smoke exhaust pipe 6 is installed in a simple manner, which improves the installation efficiency of the second smoke exhaust pipe 6 and reduces the cost of the cooking device 100.

[0080] Reference Figure 3and Figure 7 In some embodiments, the air duct assembly 2 includes: a first air guide member 23 and a second air guide member 24, the second air guide member 24 is arranged on the upper side of the inner liner 1, and the first air guide member 23 is arranged on the upper side of the second air guide member 24 and defines the above-mentioned air flow channel 21 between the first air guide member 23 and the second air guide member 24.

[0081] The air inlet 212 is arranged on the top wall of the first air guide 23. The first air guide 23 and the second air guide 24 both extend toward the front wall of the box and form an air outlet 211 arranged toward the front wall of the box. The air outlet 211 is connected to the through hole on the front wall of the box.

[0082] The guide fan 3 includes a drive motor and fan blades 31. The drive motor is arranged on the upper side of the first air guide member 23, and the fan blades 31 are arranged in the air flow channel 21. The output shaft of the drive motor passes through the air inlet and is connected to the fan blades 31 to drive the fan blades 31 to rotate.

[0083] The first exhaust port 111 and the second exhaust port 112 are both provided 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 connected to the air inlet side of the fan blade 31 through the first exhaust pipe 5, and the second exhaust port 112 is connected to the air outlet side of the fan blade 31 through the second exhaust pipe 6.

[0084] When the cooking device 100 is working, due to the expansion of gas in the cooking cavity 11, evaporation of liquid and other reasons, some exhaust gas that needs to be discharged is generated in the cooking cavity 11. The driving motor drives the fan blades 31 to rotate, so that negative pressure is generated on the air inlet side of the fan blades 31. Part of the exhaust gas in the cooking cavity 11 passes through the first exhaust port 111 and the first smoke exhaust pipe 5 and enters the air flow channel 21, and is finally discharged from the cooking space through the air outlet 211; when the fan blades 31 rotate, the air flow is driven to flow through the smoke exhaust port of the second smoke exhaust pipe 6, so that the second smoke exhaust pipe 6 generates negative pressure, and another part of the exhaust gas in the cooking cavity 11 passes through the second smoke exhaust pipe 6 and enters the air flow channel 21, and is finally discharged from the cooking space through the air outlet 211; when the fan blades 31 rotate, the air between the box body and the inner pot 1 is also sucked into the air flow channel 21 through the air inlet, and finally discharged from the cooking space through the air outlet 211.

[0085] In the embodiment of the utility model, the air duct assembly 2 is arranged on the upper side of the inner pot 1, and the first exhaust port 111 and the second exhaust port 112 are arranged on the top wall of the inner pot 1, which conforms to the characteristic that the exhaust gas is easy to flow upward, and further improves the efficiency of exhaust gas discharge in the cooking cavity 11.

[0086] It should be noted that the airflow channel 21 can be a channel independently defined by the air duct component 2, or it can be a channel jointly defined by the air duct component 2 and the outer wall of the inner liner 1. As long as a channel for airflow can be formed, the present invention does not limit this.

[0087] Reference Figure 1 、 Figure 2 and Figure 3 In some embodiments, the cooking device 100 further includes: a burner assembly 7 , which is disposed in the cooking cavity 11 to heat the cooking cavity 11 .

[0088] The cooking device 100 of the embodiment of the present invention can grill food through the burner assembly 7, thereby improving the cooking effect of the cooking device 100.

[0089] When the burner assembly 7 is working, the flammable gas burns in the burner assembly 7, and the heat generated during the combustion grills the food. When the flammable gas burns, it is easy to produce smoke. If the smoke cannot be discharged in time, the smoke will squeeze the oxygen in the cooking cavity 11, resulting in insufficient oxygen and incomplete combustion of the flammable gas, which will affect the cooking effect of the cooking device 100.
