Detailed Implementation

[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. 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.

[0033] Combination Figure 1 and Figure 2According to an embodiment of the present invention, a cooking device 100 includes a body 10. The body 10 is provided with a cooking chamber 11, a circulation channel 12, a smoke exhaust channel 13, and a heat dissipation channel 14. The circulation channel 12 is connected to the cooking chamber 11, the smoke exhaust channel 13 is connected to the cooking chamber 11 and is configured to exhaust smoke from above the cooking chamber 11, and the heat dissipation channel 14 is connected to the smoke exhaust channel 13. The cooking chamber 11 can be used to place food and heat the food; the circulation channel 12 is connected to the cooking chamber 11, and the circulation channel 12 cooperates with the cooking chamber 11 to deliver the heat generated by the heating element to the cooking chamber 11, thereby improving the heating efficiency and uniformity of the cooking chamber 11; the smoke exhaust channel 13 can be used to exhaust oil fumes or steam generated in the cooking chamber 11; the heat dissipation channel 14 can be used to dissipate heat from the element, and the heat dissipation channel 14 is connected to the smoke exhaust channel 13, that is, the heat in the heat dissipation channel 14 is discharged through the smoke exhaust channel 13.

[0034] Combination Figure 2 The cooking device 100 also includes a fan assembly 20, configured to drive flue gas to circulate between the circulation channel 12 and the cooking chamber 11, and to drive the airflow of the heat dissipation channel 14 to the exhaust channel 13. By setting the fan assembly 20 to drive the flue gas to circulate between the circulation channel 12 and the cooking chamber 11, the air in the cooking chamber 11 is mixed and circulated with the high-temperature flue gas in the circulation chamber, allowing the food in the cooking chamber 11 to be heated by the flowing hot air, improving cooking efficiency and heating uniformity. In addition, the fan assembly 20 driving the airflow in the heat dissipation channel 14 can improve the heat dissipation efficiency of the components, combined with... Figure 2 The arrows indicate the airflow direction of the heat dissipation channel 14. The airflow in the heat dissipation channel 14 flows to the smoke exhaust channel 13 and can mix with the smoke in the smoke exhaust channel 13 to reduce the exhaust temperature of the cooking equipment 100.

[0035] The cooking apparatus 100 also includes a burner 30 configured to heat items within the cooking chamber 11 using gas. For example, the cooking apparatus 100 can be connected to an external gas pipeline, allowing the high-temperature gas generated by the burner 30 to enter the cooking chamber 11 and heat the food within, overcoming the limitations of electric heating and improving the cooking efficiency of the cooking apparatus 100.

[0036] Specifically, the burner 30 generates high-temperature gas through combustion. This high-temperature gas is then sent from the circulation channel 12 to the cooking chamber 11 via the fan assembly 20. This allows the return air in the cooking chamber 11 to mix and circulate with the high-temperature flue gas in the circulation channel 12, thus heating the food in the cooking chamber 11 through the flowing hot air, improving cooking efficiency and heating uniformity. The oil fumes, steam, and other high-temperature gases generated during heating of the food in the cooking chamber 11 can be discharged from the top of the cooking chamber 11 through the exhaust channel 13. Additionally, the heat generated by the fan assembly 20 during operation can be discharged through the heat dissipation channel 14, improving the reliability of the fan assembly 20. It is understood that the steam and flue gas generated in the cooking chamber 11 have a high temperature, while the heat generated by the fan assembly 20 during operation is relatively low. The heat dissipation channel 14 connects to the exhaust channel 13, allowing the heat within the heat dissipation channel 14 to mix with the high-temperature gas discharged from the cooking chamber 11 and be discharged through the exhaust port of the exhaust channel 13. This reduces the exhaust temperature of the cooking equipment 100, improving the safety of the cooking equipment 100.

[0037] For example, the cooking device 100 can be installed in a cabinet, and by reducing the exhaust temperature of the cooking device 100, the impact on the cabinet can be reduced. Of course, the cooking device 100 of this embodiment can also be used in an open environment, and by reducing the exhaust temperature, the safety of using the cooking device 100 can be improved.

[0038] According to the embodiments of the present invention, the cooking device 100, the fan assembly 20 and the circulation channel 12 cooperate to improve the heating efficiency of the cooking device 100, the exhaust channel 13 is used to exhaust the high-temperature flue gas generated by the cooking chamber 11, the heat dissipation channel 14 is used for heat dissipation of components, and the heat dissipation efficiency of components is improved. The fan assembly 20 can drive the heat generated by the heat dissipation channel 14 to mix with the high-temperature gas generated by the cooking chamber 11 in the exhaust channel 13 and then discharge it to the outside of the cooking device 100, which can reduce the exhaust temperature of the cooking device 100 and improve the safety of the cooking device 100.

[0039] The cooking equipment 100 in this embodiment of the invention can be a gas oven, a gas microwave oven, a gas steam oven, etc.

[0040] The heat dissipation channel 14 is connected to the smoke exhaust channel 13. For example, the smoke exhaust channel 13 can extend in the vertical direction, and the heat dissipation channel 14 can be connected to the lower part of the smoke exhaust channel 13, or to the middle part of the smoke exhaust channel 13, or to the upper part of the smoke exhaust channel 13, etc.

[0041] Combination Figure 2In some embodiments of the present invention, the outlet 141 of the heat dissipation channel 14 is connected to the lower part of the exhaust channel 13, and the airflow of the heat dissipation channel 14 is mixed with the flue gas and then discharged from the exhaust channel 13. Specifically, the airflow of the heat dissipation channel 14 is discharged from the outlet 141 and mixed with the flue gas discharged from the cooking chamber 11 before being discharged from the exhaust channel 13. The outlet 141 of the heat dissipation channel 14 is connected to the lower part of the exhaust channel 13, which facilitates the heat of the heat dissipation channel 14 to be fully mixed with the high-temperature flue gas discharged from the cooking chamber 11 before being discharged, further reducing the exhaust temperature of the cooking equipment 100.

[0042] Combination Figure 2 and Figure 3 In some embodiments of the present invention, a baffle portion 131 is provided at the lower end of the exhaust duct 13, covering the lower end of the exhaust duct 13, and the baffle portion 131 is provided with an exhaust hole 1311 for the passage of fumes. The exhaust hole 1311 can guide the steam, fumes, and other fumes generated in the cooking cavity 11, control the flow rate and direction of the fumes, and ensure that the fumes enter the exhaust duct 13 from the exhaust hole 1311 and are discharged from the exhaust duct 13. In addition, the baffle portion 131 can prevent the airflow of the heat dissipation channel 14 from affecting the cooking cavity 11.

[0043] In some embodiments of the present invention, the cooking device 100 further includes a microwave heating unit configured to heat the items inside the cooking cavity 11. Microwaves can penetrate the surface of the items and rapidly heat the inside of the items, which can enrich the functions of the cooking device and meet diverse usage needs.

[0044] The exhaust vent 1311 can be circular, and its inner diameter is less than or equal to 5.5 mm. This can prevent microwaves from penetrating through the exhaust vent 1311 to the outside of the cooking equipment during operation, thus avoiding any impact on the user and improving the safety of the cooking equipment 100.

[0045] The baffle section 131 may be provided with multiple exhaust holes 1311 arranged in a matrix. The multiple exhaust holes 1311 can improve the uniformity of smoke emission and avoid excessively high smoke emission concentration in local areas. The number and size of the exhaust holes 1311 can be adjusted according to the specifications and model of the cooking equipment 100.

[0046] Additionally, the baffle portion 131 covers the lower end of the smoke exhaust channel 13. For example, the portion of the top wall of the cooking cavity 11 corresponding to the smoke exhaust channel 13 may have a smoke exhaust hole 1311 and form the baffle portion 131; or, the baffle portion 131 may be a separate component, and the baffle portion 131 may be welded or fixed to the top wall of the cooking cavity 11 by fasteners.

[0047] Combination Figure 3Furthermore, the baffle portion 131 is provided with a baffle 1312, which connects to the periphery of the exhaust port 1311 and extends upward. On the one hand, the baffle 1312 can guide the smoke discharged from the cooking chamber 11, improve the efficiency of smoke discharge, and improve the structural strength of the exhaust port 1311, reducing the impact of high-temperature smoke on the exhaust port 1311. On the other hand, the baffle 1312 connects to the periphery of the exhaust port 1311 and extends upward, which can prevent the condensate above the baffle portion 131 from flowing back from the exhaust port 1311 to the cooking chamber 11, thereby improving the cooking effect of the cooking equipment 100.

[0048] Combination Figure 4 and Figure 5 In some embodiments of the present invention, the body 10 includes an inner liner 15. The top wall of the inner liner 15 has a baffle portion 131 opposite to the lower end of the exhaust channel 13. The baffle portion 131 covers the lower end of the exhaust channel 13 and is provided with an exhaust hole 1311. Specifically, during the operation of the cooking equipment 100, the food is heated to generate high-temperature fumes such as oil fumes and steam. The fumes enter the exhaust channel 13 through the exhaust hole 1311 of the baffle portion 131 and are discharged from the outside of the cooking equipment 100. The baffle portion 131 is located on the top wall of the inner liner 15 to guide the fumes and facilitate their discharge. The exhaust hole 1311 can control the flow rate and direction of the fumes, ensuring that the fumes enter the exhaust channel 13 through the exhaust hole 1311 and are discharged from the exhaust channel 13. In addition, the baffle portion 131 can prevent the airflow of the heat dissipation channel 14 from affecting the cooking cavity 11.

[0049] Combination Figure 6 and Figure 7 In some embodiments of the present invention, the top wall of the inner liner 15 is provided with an upwardly protruding bulge 151, the smoke exhaust hole 1311 is provided on the top wall of the bulge 151, and the lower end of the smoke exhaust channel 13 is surrounded around the outer periphery of the bulge 151, which can improve the structural strength of the top wall corresponding to the smoke exhaust channel 13.

[0050] For example, the smoke exhaust duct 13 can be enclosed by a metal baffle, and the lower end of the smoke exhaust duct 13 is arranged around the outer periphery of the protrusion 151, which can facilitate the positioning of the smoke exhaust duct 13 and improve installation efficiency.

[0051] Alternatively, the top wall of the inner liner 15 can be a metal part, and the protrusion 151 can be formed by sheet metal stamping, or the baffle portion 131 can be welded to the top wall of the inner liner 15.

[0052] Combination Figure 5 and Figure 6In some embodiments of the present invention, the body 10 further includes an outer layer plate 16, which is disposed on the outside of the inner liner 15. The top wall of the outer layer plate 16 is provided with a mating hole 161, which is opposite to the exhaust hole 1311 in the vertical direction. The exhaust channel 13 includes a first annular wall 132, which is opposite to the mating hole 161. Specifically, the first annular wall 132 may be disposed above the baffle portion 131. The smoke in the cooking cavity 11 can first enter the first annular wall 132 through the exhaust hole 1311, and the first annular wall 132 guides the smoke discharged from the exhaust hole 1311 to the outside of the outer layer plate 16.

[0053] The outer layer 16 can isolate the heat from the cooking cavity 11. For example, the outer layer 16 can fix a cooling fan and has a channel for heat dissipation for the components.

[0054] Combination Figure 5 and Figure 7 Furthermore, the upper periphery of the first annular wall 132 is provided with an ear 1321, which is stacked on the upper surface of the outer layer plate 16 and positioned on the outer layer plate 16 from top to bottom by a fastener, which facilitates the installation of the first annular wall 132 and improves the installation efficiency. Moreover, the ear 1321 is stacked on the surface of the outer layer plate 16, which can improve the structural stability of the first annular wall 132, thereby improving the structural stability of the smoke exhaust channel 13.

[0055] Combination Figure 5 and Figure 7 In some embodiments of the present invention, the exhaust channel 13 further includes a second annular wall 133, the lower end of which is connected to the outer layer plate 16 and is distributed vertically and communicates with the first annular wall 132. Specifically, the smoke generated in the cooking chamber 11 has a high temperature and easily flows upward after being discharged from the cooking chamber 11. The high-temperature gas first enters the first annular wall 132 from the exhaust hole 1311 and then enters the second annular wall 133.

[0056] Furthermore, in the top-down projection, the first annular wall 132 falls inside the second annular wall 133. In other words, the cross-sectional area of ​​the second annular wall 133 channel is larger than the cross-sectional area of ​​the first annular wall 132, thus optimizing the exhaust flow path of the smoke exhaust channel 13.

[0057] Combination Figure 4 and Figure 7 In some embodiments of the present invention, the side of the second annular wall 133 is provided with a docking hole 1331, wherein the outlet 141 of the heat dissipation channel 14 docks with the docking hole 1331, and the airflow in the heat dissipation channel 14 can enter the second annular wall 133 from the outlet 141 through the docking hole 1331 and mix with the smoke discharged from the cooking cavity 11, thereby reducing the exhaust temperature of the exhaust channel 13.

[0058] Alternatively, the outlet 141 of the heat dissipation channel 14 passes through the docking hole 1331, which facilitates the airflow of the heat dissipation channel 14 to enter the smoke exhaust channel 13, so that the smoke in the cooking cavity 11 is mixed with the airflow of the heat dissipation channel 14, thereby reducing the temperature of the smoke exhaust.

[0059] The second annular wall 133 has a docking hole 1331 on its side wall. The outlet 141 of the heat dissipation channel 14 is docked with or passes through the docking hole 1331. This prevents the steam generated in the exhaust channel 13 from forming condensate and flowing back into the heat dissipation channel 14, which would affect the performance of the fan assembly 20 and improve the reliability of the cooking equipment 100. For example, in the steam-bake mode of the cooking equipment 100, water vapor is easily generated in the cooking cavity 11. The water vapor enters the first annular wall 132 from the exhaust hole 1311 and then enters the second annular wall 133 to be discharged outside the cooking equipment 100. During the discharge process, the water vapor is prone to condensation. The outlet 141 of the heat dissipation channel 14 is located on the side wall of the second annular wall 133, which can prevent the condensate from flowing back into the heat dissipation channel 14 and avoid affecting the components.

[0060] In addition, the outlet 141 of the heat dissipation channel 14 cooperates with the second annular wall 133, and the cooking cavity 11 and the heat dissipation channel 14 are connected by the first annular wall 132, which can reduce the impact of the airflow of the heat dissipation channel 14 on the cooking cavity 11.

[0061] Specifically, the first annular wall 132 can surround the first part of the exhaust duct 13, and the second annular wall 133 can surround the second part of the exhaust duct 13. The first part is located below the second part, and the outlet 141 of the heat dissipation channel 14 can be connected to the second part. The first part can isolate the airflow discharged from the heat dissipation channel 14 to prevent the airflow of the heat dissipation channel 14 from affecting the cooking cavity 11. In addition, it can also prevent the steam generated by the exhaust duct 13 from condensing and flowing back into the heat dissipation channel 14, thus affecting the performance of the fan assembly 20.

[0062] Combination Figure 8 In some embodiments of the present invention, the exhaust duct 13 is configured to extend in the vertical direction. It can be understood that the smoke generated by the cooking device 100 during operation and the airflow generated by the fan assembly 20 have high heat. Extending the exhaust duct 13 in the vertical direction helps to improve the exhaust efficiency of the cooking device 100.

[0063] Combination Figure 8 In some embodiments of the present invention, the upper end of the exhaust duct 13 extends out of the top surface of the body 10, which facilitates the discharge of the smoke generated in the cooking chamber 11 and the hot airflow in the heat dissipation duct 14 to the outside of the cooking chamber 11, thereby improving the heat dissipation efficiency of the cooking equipment 100.

[0064] Combination Figure 8In some embodiments of the present invention, the heat dissipation channel 14 includes a first channel segment 142 and a second channel segment 143. The first channel segment 142 extends in the vertical direction, and the second channel segment 143 is perpendicular to the first channel segment 142 and connects the upper end of the first channel segment 142 and the exhaust channel 13, so that the structure of the cooking equipment 100 is compact and the impact of the exhaust duct 13 on the fan assembly 20 is reduced, and the condensate of the exhaust channel 13 is prevented from entering the heat dissipation channel 14.

[0065] The second channel 143 can be configured to extend in the front-to-back direction to optimize the flow path of the heat dissipation channel 14, making the cooking device 100 compact and improving heat dissipation efficiency.

[0066] Specifically, in combination Figure 8 The arrows indicate the airflow direction of the exhaust gas in the cooking chamber 11 and the airflow direction of the heat dissipation channel 14. During the operation of the cooking equipment 100, the high-temperature steam and flue gas generated in the cooking chamber 11 enter the exhaust channel 13 through the exhaust port 131. The heat generated by the fan assembly 20 during operation can be driven by the fan assembly 20 to enter the second channel section 143 from the first channel section 142 and then enter the exhaust channel 13 from the outlet 141. It mixes with the high-temperature flue gas discharged from the cooking chamber 11 and is then discharged to the outside of the cooking equipment 100, thereby reducing the exhaust temperature of the cooking equipment 100 and reducing the impact on the external environment.

[0067] For example, the fan assembly 20 may include a motor and heat dissipation blades. The heat dissipation blades dissipate heat from the motor while sending airflow to the exhaust duct 13. The airflow first passes through the first channel section 142, then through the second channel section 143, and enters the exhaust duct 13 from the outlet 141. The first channel section 142 extends vertically to facilitate the upward flow of hot air from the heat dissipation duct 14 into the second channel section 143. The second channel section 143 is perpendicular to the first channel section 142, which can effectively prevent the steam condensate generated by the cooking equipment 100 in the steam-bake mode from flowing back into the heat dissipation duct 14, reducing the impact on the fan assembly 20 and improving the reliability of the cooking equipment 100.

[0068] Combination Figure 8In some embodiments of the present invention, the fan assembly 20 includes a rotary drive 21, a first impeller 22, and a second impeller 23. The rotary drive 21 is pulverizedly connected to the first impeller 22 and the second impeller 23. The rotary drive 21 and the first impeller 22 are disposed in the heat dissipation channel 14, and the second impeller 23 is disposed in the circulation channel 12. Specifically, the rotary drive 21 drives the second impeller 23 to rotate, which can cause the airflow in the circulation channel 12 to circulate with the airflow in the cooking chamber 11, thereby improving the heating efficiency and uniformity of the cooking equipment 100. The rotary drive 21 drives the first impeller 22 to rotate, which can dissipate heat from the rotary drive 21 and send the hot airflow to the exhaust channel 13, so that the airflow in the heat dissipation channel 14 mixes with the exhaust gas discharged from the cooking chamber 11, thereby reducing the exhaust temperature of the cooking equipment 100.
