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 Figures 1 to 3 According 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, and the smoke exhaust channel 13 is connected to the cooking chamber 11 and configured to exhaust smoke from above the cooking chamber 11. 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 fumes or steam generated in the cooking chamber 11 can be discharged through the smoke exhaust channel 13, and the heat dissipation channel 14 can be used for heat dissipation of the elements.

[0034] Combination Figure 2 The cooking apparatus 100 may further include 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, thus 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. (See attached diagram.) Figure 2 The arrows indicate the airflow direction of the heat dissipation channel.

[0035] Combination Figure 2 The cooking device 100 may also include a burner 30, which is configured to heat the items in the cooking chamber 11 using gas. For example, the cooking device 100 may be connected to an external gas pipeline. The high-temperature gas generated by the combustion of the burner 30 enters the cooking chamber 11 to heat the food in the cooking chamber 11, thus overcoming the limitations of electric heating and improving the cooking efficiency of the cooking device 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 by heating the food in the cooking chamber 11 can be discharged from the top of the cooking chamber 11 through the exhaust channel 13. In addition, 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.

[0037] Combination Figure 1 and Figure 3 The main body 10 includes a smoke baffle 15, which divides the exhaust channel 13 into a first channel 131 and a second channel 132. The inlet of the first channel 131 connects to the cooking chamber 11, and the inlet of the second channel 132 connects to the heat dissipation channel 14. This means that fumes or steam generated in the cooking chamber 11 can be discharged through the first channel 131, and airflow from the heat dissipation channel 14 can be discharged through the second channel 132. It is understood that the steam and fumes generated in the cooking chamber 11 have different heat and pressure than the airflow generated by the fan assembly 20 during operation. By separating the first channel 131 and the second channel 132 with the smoke baffle 15, the mutual influence between the first channel 131 and the second channel 132 can be reduced, preventing airflow from the first channel 131 from entering the second channel 132, or airflow from the second channel 132 from entering the first channel 131, thereby improving the exhaust and heat dissipation efficiency and the operational stability of the cooking equipment 100.

[0038] For example, when the fan assembly 20 is working, the air pressure of the heat dissipation channel 14 is high and the exhaust air pressure of the cooking chamber 11 is low. The airflow of the heat dissipation channel 14 is easy to backflow into the cooking chamber 11, causing problems such as reduced cooking efficiency. By setting the smoke baffle 15, the impact of the heat dissipation channel 14 on the cooking chamber 11 can be reduced, and the working stability of the cooking equipment 100 can be improved.

[0039] According to the cooking device 100 of the present invention, the fumes generated by heating food in the cooking chamber 11 can be discharged from the first channel 131 of the exhaust channel 13, the heat dissipation channel 14 is used for heat dissipation of components to improve the heat dissipation efficiency of components, and is discharged from the second channel 132 of the exhaust channel 13. By setting a smoke baffle 15 to separate the first channel 131 and the second channel 132 in the exhaust channel 13, the mutual influence between the cooking chamber 11 and the heat dissipation channel 14 can be reduced, thereby improving cooking efficiency and heat dissipation efficiency.

[0040] The cooking equipment 100 in this embodiment of the invention can be a gas oven, a gas microwave oven, a gas steam oven, etc.

[0041] The smoke baffle 15 may be provided with a baffle connected to the bottom wall of the smoke exhaust channel 13. That is, the first channel 131 and the second channel 132 may be arranged side by side. For example, the smoke baffle 15 may include a baffle extending in the vertical direction, and the lower edge of the baffle is connected to the bottom wall of the smoke exhaust channel 13; or the smoke baffle 15 may be connected below the outlet 141 of the heat dissipation channel 14. For example, the smoke baffle 15 may include a baffle extending in the vertical direction, and the lower edge of the baffle is connected to the outlet 141 of the heat dissipation channel 14. The baffle is opposite to the outlet 141 of the heat dissipation channel 14 to separate the first channel 131 and the second channel 132 in the smoke exhaust channel 13.

[0042] Optionally, the smoke baffle 15 may also include a check valve disposed in the first channel 131. The check valve is configured to unidirectionally flow from the cooking chamber 11 to the first channel 131 to prevent the airflow from the second channel 132 from flowing back into the cooking chamber 11 and affecting the cooking efficiency of the cooking chamber 11.

[0043] In addition, the steam generated by heating food in the cooking cavity 11 can be directly discharged to the outside of the cooking equipment 100 from the first channel 131, and the airflow in the heat dissipation channel 14 can be directly discharged to the outside of the cooking equipment 100 from the second channel 132; or, the smoke exhaust channel 13 may also include a third channel 133, and the airflow in the first channel 131 and the airflow in the second channel 132 can converge into the third channel 133 and be discharged to the outside of the cooking equipment 100 from the third channel 133.

[0044] Combination Figure 3 In some embodiments of the present invention, the exhaust duct 13 further includes a third duct 133. The inlet of the first duct 131 and the inlet of the second duct 132 are separated, and the outlet of the first duct 131 is connected to the third duct 133, and the outlet of the second duct 132 is also connected to the third duct 133. Specifically, the flue gas in the first duct 131 can mix with the airflow in the second duct 132 in the third duct 133. 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 outlets of the first duct 131 and the second duct 132 are both connected to the third duct 133. The heat in the heat dissipation duct 14 can mix with the high-temperature gas discharged from the cooking chamber 11 and be discharged through the third duct 133, which can reduce the exhaust temperature of the cooking equipment 100 and improve the safety of the cooking equipment 100.

[0045] Combination Figure 3 In some embodiments of the present invention, the third channel 133 is disposed above the first channel 131 and the second channel 132, so that the airflow of the heat dissipation channel 14 can mix with the high-temperature flue gas discharged from the cooking chamber 11 and then be discharged, thereby reducing the exhaust temperature of the cooking device 100.

[0046] Combination Figure 3 In some embodiments of the present invention, the first channel 131 and the second channel 132 are arranged side by side below the third channel 133, which facilitates the mixing of the airflow of the first channel 131 and the airflow of the second channel 132 in the third channel 133, thereby reducing the exhaust temperature of the cooking device 100 and improving the safety of the cooking device 100.

[0047] Combination Figure 3 In some embodiments of the present invention, the smoke baffle 15 includes a first baffle 151 disposed at the lower end of the smoke exhaust channel 13. The first baffle 151 covers the lower end of the smoke exhaust channel 13, and the first baffle 151 forms a smoke exhaust hole 1511 at the lower end of the smoke exhaust channel 13 for smoke to pass through and enter the first channel 131. The smoke exhaust hole 1511 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 first channel 131 from the smoke exhaust hole 1511 and are discharged from the first channel 131.

[0048] The first baffle 151 may be provided with multiple exhaust holes 1511 arranged in a matrix. Multiple exhaust holes 1511 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 1511 can be adjusted according to the specifications and model of the cooking equipment 100.

[0049] In addition, the first baffle 151 is provided at the lower end of the smoke exhaust channel 13 and forms a smoke exhaust hole 1511. For example, the part of the top wall of the cooking cavity 11 corresponding to the smoke exhaust channel 13 can be provided with a smoke exhaust hole 1511 and form the first baffle 151 of the smoke blocking member 15; or, the first baffle 151 can be a separate component relative to the top wall of the cooking cavity 11, and the first baffle 151 can be welded or fixed to the top wall of the cooking cavity 11 by fasteners.

[0050] Furthermore, the first baffle 151 is provided with baffle ribs, which connect to the periphery of the exhaust port 1511 and extend upward. On the one hand, the baffle ribs can guide the flue gas discharged from the cooking chamber 11, improve the efficiency of flue gas discharge, and improve the structural strength of the exhaust port 1511, reducing the impact of high-temperature flue gas on the exhaust port 1511; on the other hand, the baffle ribs connecting to the periphery of the exhaust port 1511 and extending upward can prevent condensate above the first baffle 151 from flowing back from the exhaust port 1511 to the cooking chamber 11, thereby improving the cooking effect of the cooking equipment 100.

[0051] Optionally, the cooking device 100 also includes a microwave heating unit configured to heat items within the cooking cavity 11. Microwaves can penetrate the surface of the items and rapidly heat their interiors, enriching the functionality of the cooking device 100 and meeting diverse usage needs.

[0052] The exhaust vent 1511 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 1511 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.

[0053] Combination Figure 3 In some embodiments of the present invention, the outlet 141 of the heat dissipation channel 14 is located on the side wall of the smoke exhaust channel 13. The smoke baffle 15 further includes a second baffle 152, which is located in the smoke exhaust channel 13 and extends vertically. The lower end of the second baffle 152 is connected to the first baffle 151, and the smoke exhaust hole 1511 is located on the side of the second baffle 152 away from the heat dissipation channel 14. The lower end of the second baffle 152 separates the heat dissipation channel 14 from the smoke exhaust hole 1511, preventing the airflow of the heat dissipation channel 14 from entering the cooking chamber 11 through the smoke exhaust hole 1511, or preventing the smoke exhausted from the cooking chamber 11 from entering the heat dissipation channel 14. The smoke exhausted from the smoke exhaust hole 1511 can be discharged through the first channel 131, and the airflow discharged from the heat dissipation channel 14 can be discharged through the second channel 132, thus optimizing the exhaust flow channel and heat dissipation flow channel of the cooking equipment 100.

[0054] Furthermore, the second baffle 152 is directly opposite the outlet 141 of the heat dissipation channel 14, which facilitates the blocking of the airflow of the heat dissipation channel 14 from entering the first channel 131 by the second baffle 152, thereby reducing the impact of the airflow of the heat dissipation channel 14 on the cooking cavity 11 and improving the working stability of the cooking equipment 100.

[0055] Combination Figure 2 and Figure 3 In some embodiments of the present invention, the body 10 includes an inner liner 16, the top wall of which is provided with an upwardly protruding bulge 161, a smoke exhaust hole 1511 is provided on the top wall of the bulge 161, and the lower end of the smoke exhaust channel 13 surrounds the outer periphery of the bulge 161. Exemplarily, the smoke exhaust channel 13 can be formed by a metal baffle, and the lower end of the smoke exhaust channel 13 surrounding the outer periphery of the bulge 161 facilitates positioning of the smoke exhaust channel 13 and improves installation efficiency. Alternatively, the top wall of the inner liner 16 can be a metal part, and the bulge 161 can be formed by sheet metal stamping.

[0056] Combination Figure 3 and Figure 4In some embodiments of this utility model, the body 10 further includes an outer layer plate 17, which is disposed on the outside of the inner liner 16. The top wall of the outer layer plate 17 is provided with a mating hole 171, which is opposite to the exhaust hole 1511 in the vertical direction. The exhaust channel 13 includes a first annular wall 134, which is opposite to the mating hole 171. Specifically, the first annular wall 134 can be disposed above the exhaust hole 1511. The smoke in the cooking cavity 11 can first enter the first annular wall 134 through the exhaust hole 1511, and the first annular wall 134 guides the smoke discharged from the exhaust hole 1511 to the outside of the outer layer plate 17.

[0057] The outer layer 17 can isolate the heat from the cooking cavity 11. For example, the outer layer 17 can fix a cooling fan and has a channel for heat dissipation for the components.

[0058] Furthermore, the exhaust duct 13 also includes a second annular wall 135, the lower end of which is connected to the outer layer plate 17 and is distributed and connected to the first annular wall 134 vertically. Specifically, the smoke generated in the cooking cavity 11 has a high temperature and easily flows upward after being discharged from the cooking cavity 11. The high-temperature gas first enters the first annular wall 134 from the exhaust hole 1511 and then enters the second annular wall 135.

[0059] In the top-down projection, the first annular wall 134 falls inside the second annular wall 135. In other words, the cross-sectional area of ​​the channel of the second annular wall 135 is larger than the cross-sectional area of ​​the first annular wall 134, thus optimizing the exhaust channel of the cooking cavity 11.

[0060] In combination Figure 4 In some embodiments of the present invention, the side of the second annular wall 135 is provided with a docking hole 1351, wherein the outlet 141 of the heat dissipation channel 14 docks with the docking hole 1351, and the airflow in the heat dissipation channel 14 can enter the second annular wall 135 from the outlet 141 through the docking hole 1351 and enter the second channel 132.

[0061] Alternatively, the outlet 141 of the heat dissipation channel 14 is provided through the docking hole 1351, which facilitates the airflow of the heat dissipation channel 14 into the second channel 132 and improves the connection stability between the heat dissipation channel 14 and the smoke exhaust channel 13.

[0062] In some embodiments of the present invention, the outlet 141 of the heat dissipation channel 14 is located on the side wall of the smoke exhaust channel 13, and the smoke baffle 15 includes a third baffle. The third baffle is located in the smoke exhaust channel 13 and extends in the vertical direction. The lower edge of the third baffle is connected to the lower part of the outlet 141 of the heat dissipation channel 14. The third baffle is opposite to the outlet 141 of the heat dissipation channel 14. By setting the third baffle, the heat dissipation channel 14 and the cooking cavity 11 can be separated, so as to avoid the airflow of the heat dissipation channel 14 from affecting the cooking cavity 11 and improve the working stability of the cooking equipment 100.

[0063] Combination Figure 3 In 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 and the smoke from the cooking chamber 11 are discharged from the exhaust channel 13. Specifically, the airflow of the heat dissipation channel 14 is discharged from the outlet 141 and can mix with the smoke 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 mixing of the heat from the heat dissipation channel 14 with the high-temperature smoke discharged from the cooking chamber 11 before discharge, thereby reducing the exhaust temperature of the cooking equipment 100. In conjunction with the foregoing, the steam and smoke 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 airflow in the heat dissipation channel 14 can mix with the high-temperature gas discharged from the cooking chamber 11 in the exhaust channel 13 before discharge, which can reduce the exhaust temperature of the cooking equipment 100 and improve the safety of the cooking equipment 100.

[0064] In some embodiments of the present invention, the exhaust duct 13 is configured to extend in the vertical direction. It is 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.

[0065] 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 cavity 11 and the hot airflow in the heat dissipation duct 14 to the outside of the cooking cavity 11, thereby improving the heat dissipation efficiency of the cooking equipment 100.

[0066] Combination Figure 5 In some embodiments of the present invention, the heat dissipation channel 14 includes a first segment 142 and a second segment 143. The first segment 142 extends in the vertical direction, and the second segment 143 is perpendicular to the first segment 142 and connects the upper end of the first segment 142 and the second channel 132, so that the structure of the cooking device 100 is compact and the influence of the flue gas of the first channel 131 on the fan assembly 20 is reduced, and the condensate of the first channel 131 is prevented from entering the heat dissipation channel 14.

[0067] The second channel 132 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.

[0068] For example, during the operation of the cooking equipment 100, the high-temperature steam and fumes generated in the cooking chamber 11 enter the first channel 131 through the exhaust port 1511. The heat generated by the fan assembly 20 during operation can be driven by the fan assembly 20 to enter the second section 143 from the first section 142 and then enter the second channel 132 from the outlet 141. The second channel 132 extends in the front-back direction to prevent the condensate generated in the first channel 131 from entering the heat dissipation channel 14 and affecting the performance of the fan assembly.

[0069] Combination Figure 3 In addition, the exhaust duct 13 may also include a third duct 133. The third duct 133 may be located above the first duct 131 and the second duct 132. The airflow of the second duct 132 may be mixed with the high-temperature flue gas discharged from the cooking chamber 11 in the third duct 133 and 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.

[0070] 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.

[0071] 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 second channel 132. The airflow first passes through the first section 142, then through the second section 143, and enters the second channel 132 from the outlet 141. The first section 142 extends vertically to facilitate the upward flow of hot air from the heat dissipation channel 14 into the second section 143. The second section 143 is perpendicular to the first 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 channel 14, reducing the impact on the fan assembly 20 and improving the reliability of the cooking equipment 100.

[0072] Combination Figure 5 In 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 connected to the first impeller 22 and the second impeller 23 in a transmission manner. 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.

[0073] Specifically, the rotary drive 21 drives the second impeller 23 to rotate, which can cause the airflow in the circulation channel 12 and the airflow in the cooking cavity 11 to circulate, which can improve 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 second channel 132 of the exhaust channel 13. The first impeller 22 can improve the heat dissipation efficiency of the fan assembly 20 and improve the reliability of the fan assembly.
