Description

Technical Field

[0001] This invention relates to the field of cooktops, and more particularly to an integrated cooktop with a cooking device. Background Technology

[0002] An integrated cooktop is a household appliance that integrates a cooktop with other kitchen appliances. Current technology typically integrates the cooktop and cooking device together, allowing the integrated cooktop to meet basic cooking needs such as stir-frying, baking, and steaming. Currently, integrated cooktops on the market generally place the cooktop above the cooking device, with the gas produced by the cooking device being exhausted upwards through the rear side of the cooktop panel. For example, Chinese utility model patent number ZL 202022216967.7 (authorization announcement number CN214370372U).

[0003] Furthermore, current cooking appliances generally suffer from poor dehumidification in baking mode, affecting baking results, especially when cooking ingredients with high moisture content. To solve this problem, a blower is typically used to force cold outside air into the inner cavity, compressing the moisture and achieving strong dehumidification. For example, Chinese utility model patent ZL 202122405399.X (authorization announcement number CN216307871U) addresses this. While existing blower methods can solve the problems of excessive humidity in the inner cavity during baking mode and the direct spraying of residual gases (such as hot air or steam) from the inner cavity at the end of cooking, adding an extra blower increases production costs and complicates the internal structure of the cooking appliance. In addition, directly blowing cold outside air into the inner cavity disrupts the uniformity of the internal temperature field, and blowing cold air back into the inner cavity after cooking causes the cooked food to cool, affecting the cooking results. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide an integrated stove with a cooking device that can achieve forced exhaust of gas inside the inner tank without the need for an additional blower, in contrast to the prior art.

[0005] The second technical problem to be solved by the present invention is to provide an integrated stove with cooking device that can achieve strong exhaust of gas inside the inner tank without the need for an additional blower, and with good exhaust effect.

[0006] The third technical problem to be solved by the present invention is to provide an integrated stove with a cooking device that can achieve strong exhaust of gas inside the inner pot without the need for an additional blower, and can avoid affecting the uniformity of the temperature field inside the inner pot.

[0007] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is as follows: an integrated stove with a cooking device, comprising a cooking device and a stove mounted on the cooking device, the cooking device comprising an inner liner having a first sidewall, wherein a hot air baffle is provided on the side of the inner liner where the first sidewall is located to form a hot air chamber, and the hot air baffle includes a hot air inlet located in the center and a hot air outlet located on the side of the hot air inlet, and a hot air fan is installed on the first sidewall of the inner liner, the impeller of the hot air fan being located in the hot air chamber and facing the hot air inlet, characterized in that...

[0008] It also includes air chambers located outside the aforementioned inner liner. Each air chamber has an air outlet, an air inlet, and a first air guide port that communicate with the outside. The air outlet is located on one side of the air chamber, while the air inlet and the first air guide port are located on the other side of the air chamber, with the air inlet and the first air guide port spaced apart.

[0009] An exhaust port is provided on the first side wall of the inner liner, and this exhaust port is located outside the horizontal projection of the impeller on the first side wall. A second air guide port, lower in height than the exhaust port and located outside the hot air chamber, is also provided on the other side wall of the inner liner. The exhaust port is in fluid communication with the air inlet, and the second air guide port is in fluid communication with the first air guide port. The hot air blower has at least a first rotational speed and a second rotational speed greater than the first rotational speed.

[0010] During the dehumidification phase of the baking mode or when cooking is finished, the hot air blower rotates at the second speed, and the second air vent introduces outside air into the inner cavity.

[0011] Furthermore, the cooktop is equipped with a heat dissipation channel to dissipate heat from electrical components (e.g., power board, display board, etc.) that generate heat during operation. The air chamber also has an air inlet, which is fluidly connected to the heat dissipation outlet of the heat dissipation channel. Thus, during the dehumidification phase of the baking mode or at the end of cooking, the warm heat dissipation gas in the heat dissipation channel can enter the air chamber through the air inlet, and then mix with the exhaust air from the first air vent before entering the inner liner. This prevents cold air from directly entering the inner liner and affecting the temperature uniformity of the inner liner, while also preventing the cooked food placed in the inner liner from cooling down.

[0012] Furthermore, the air inlet includes a first air inlet and a second air inlet spaced apart, wherein the first air inlet corresponds to the aforementioned exhaust port and the second air inlet corresponds to the aforementioned second air guide port.

[0013] The first air inlet is positioned at a height lower than the air outlet but higher than the air inlet. The first air inlet is located on one side of the air inlet, and the air intake direction of the first air inlet is towards the air outlet. The air intake direction of the first air inlet intersects with the air intake direction of the air outlet. In this way, the airflow entering the air chamber through the first air inlet can mix with the airflow at the air inlet and accelerate the airflow towards the air outlet of the air chamber, thereby increasing the air intake speed of the air inlet and thus increasing the exhaust speed of the inner liner's exhaust port.

[0014] The second air inlet is positioned lower than the air outlet but higher than the second air guide port. The second air inlet is located to one side of the second air guide port, and its air intake direction faces the second air guide port, intersecting with the air outlet direction of the second air inlet. This allows the airflow entering the air chamber through the second air inlet to mix with the airflow exiting the air chamber through the first air guide port, accelerating the exit flow and thus increasing the airflow velocity through the second air guide port, which in turn increases the airflow velocity through the first air guide port of the inner liner.

[0015] Furthermore, the airflow direction of both the air inlet and the second air guide is vertical, while the airflow direction of both the first and second air inlets is horizontal. This allows the airflow entering the air chamber through the first air inlet to better replenish the kinetic energy of the airflow at the air inlet, while the airflow entering through the second air inlet has a downward vector, thus better accelerating the airflow exiting through the first air guide.

[0016] Furthermore, the stove includes a base with an upper section and a panel covering the opening in the base. An exhaust vent is provided on the rear side of the panel. The gas chamber is disposed within the stove, and its outlet is in fluid communication with the exhaust vent. This allows the gas entering the gas chamber to be better exhausted through the outlet, while also allowing outside air to enter the gas chamber more effectively.

[0017] Furthermore, the lower surface of the panel is covered with an air box at the exhaust window to form the air chamber, and the upper opening of the air box constitutes the air outlet, thereby better forming the air chamber structure and facilitating the connection between the air outlet of the air chamber and the exhaust window of the panel.

[0018] The aforementioned air inlet and first air guide are respectively located on the bottom wall of the air box, while the aforementioned first air inlet and second air inlet are respectively located on the side wall of the air box. The first air inlet is opposite to the aforementioned air inlet, and the second air inlet is opposite to the aforementioned second air guide. The air intake direction of the first air inlet is upward. In this way, when the heat dissipation gas in the heat dissipation channel enters the air chamber through the first air inlet, it forms an upward air intake airflow. When it mixes with the air intake airflow at the air inlet, it can replenish the kinetic energy of the air intake airflow without turning. At the same time, it can guide the air intake airflow to the air outlet of the air chamber, improve the smoothness of the air intake at the air inlet, and thus improve the smoothness of the air exhaust at the air outlet. The air intake direction of the second air inlet is downward. In this way, the heat dissipation gas in the heat dissipation channel flows into the air chamber from top to bottom, thereby better accelerating the gas to flow out of the air chamber through the first air guide.

[0019] Furthermore, the first and second air inlets are located on the same side wall of the aforementioned air box. This facilitates the flow of heat dissipation gas from the heat dissipation channel into the first and second air inlets respectively, and also makes the airflow in each air passage within the air chamber more regular, avoiding collisions and mixing that could lead to airflow energy loss.

[0020] Furthermore, the edge of the first air inlet is inclined upward from the outside to the inside relative to the air box, thereby realizing air intake from the bottom to the top of the first air inlet, while the edge of the second air inlet is inclined downward from the outside to the inside relative to the air box, thereby realizing air intake from the top to the bottom of the second air inlet.

[0021] Furthermore, the first air inlet is formed by horizontally extending first air inlet holes arranged vertically at intervals, and the channels of each first air inlet hole are inclined upwards from the outside to the inside relative to the air box, thereby allowing the heat dissipation gas to flow more smoothly upwards into the air chamber and better mix with the intake airflow of the air inlet.

[0022] Accordingly, the second air inlet is formed by horizontally extending second air inlets arranged vertically at intervals, and the channels of each second air inlet are inclined upward from the outside to the inside relative to the air box, so that the heat dissipation gas can flow downward into the air chamber more smoothly and better act on the airflow of the second air guide.

[0023] Furthermore, the system also includes a water collection box disposed within the aforementioned air box. The upper part of the water collection box is open, forming a condensate outlet that communicates vertically with the air outlet of the air box. A first condensate outlet and a second condensate outlet are spaced apart and arranged side-by-side on the bottom wall of the water collection box. The first condensate outlet is fluidly connected to the aforementioned air inlet, while the second condensate outlet is fluidly connected to the aforementioned first air guide outlet. The first and second air inlets are located on top of the water collection box. By providing the water collection box, the condensate formed in the air box can be collected, preventing condensate from flowing freely throughout the air box.

[0024] Furthermore, the exhaust port is located at the upper left end of the back side wall of the inner liner, while the second air guide port is located at the lower rear end of the right side wall of the inner liner. This allows for a better pressure differential between the exhaust port and the second air guide port during dual-path convection circulation, thus ensuring a better dual-path convection circulation effect.

[0025] Furthermore, the distance between the exhaust port and the upper edge of the back side wall of the inner liner is less than or equal to 1 / 3 of the height of the back side wall, which is conducive to the upward floating of hot air and its accumulation at the exhaust port.

[0026] Furthermore, the distance between the second air inlet and the lower edge of the right side wall of the inner liner is less than or equal to 1 / 3 of the height of the right side wall, which is conducive to the sinking of cold air at the first air inlet. Thus, when a dual-path convection circulation is formed, the outside air entering through the first air inlet can better compress the hot air in the inner liner and move towards the exhaust port.

[0027] Furthermore, the hot air outlet of the hot air baffle includes a first hot air outlet located at the lower right corner of the hot air baffle, and the lowest point of the second air guide is higher than the lowest point of the first hot air outlet. In this way, the airflow from the first hot air outlet can converge with the outside air entering the inner liner through the second air guide, allowing outside air to enter the inner liner more quickly.

[0028] Furthermore, the first hot air outlet is composed of elongated, evenly spaced air outlet holes extending to the left and right. This facilitates the convergence of the airflow from the first hot air outlet and the airflow from the second air guide port at this location.

[0029] Furthermore, the exhaust port is connected to the air inlet via an exhaust pipe, and the second air guide port is connected to the first air guide port via an air guide pipe. Both the exhaust pipe and the air guide pipe have a diameter of 8mm ≤ d ≤ 12mm. This facilitates better exhaust performance under different cooking modes.

[0030] Furthermore, during the dehumidification stage of the baking mode or at the end of the cooking process, the second rotation speed of the hot air blower is 1700r / min to 2100r / min, which is conducive to better forming a dual-path convection circulation effect.

[0031] Compared with the prior art, the advantages of this invention are as follows: Exhaust vents and second air guide vents are respectively provided on different side walls of the inner liner. The exhaust vents are located in the hot air chamber and beyond the horizontal projection of the impeller onto the first side wall (the inner liner side wall where the exhaust vents are located), while the second air guide vents are located outside the hot air chamber and are positioned lower than the exhaust vents. Thus, during the dehumidification stage of the baking mode or at the end of cooking, the hot air blower rotates at a second speed. The high-speed rotation of the hot air blower causes hot air to accumulate at the exhaust vent, where the air pressure is greater than atmospheric pressure. The hot air then enters the air chamber through the air inlet via the exhaust vent. At this time, a negative pressure is formed at the first air inlet of the air chamber relative to the air inlet and is lower than the atmospheric pressure. Then, the cold air from the outside enters the air chamber through the air outlet and enters the inner liner through the second air inlet on the inner liner through the first air inlet. It also squeezes the hot air in the inner liner from bottom to top and flows to the exhaust port, forming a dual-path convection circulation effect in the inner liner and the air chamber. This achieves strong exhaust of moisture in the baking mode or strong exhaust of the remaining gas in the inner liner after cooking.

[0032] Compared with the prior art, the present invention does not require the addition of a blower at the second air inlet. It only requires designing the opening positions of the exhaust port and the second air inlet on different side walls of the inner liner and the rotation speed of the hot air blower to achieve the technical effect of blower exhaust.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0044] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this invention can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0045] like Figures 1-10 As shown, an integrated stove with a cooking device includes a cooking device 1 and a stove 2 mounted on the cooking device 1. The cooking device 1 includes an inner liner 10 with a first side wall (specifically, the back side wall of the inner liner in this embodiment). A hot air baffle 11 is provided on the side of the inner liner 10 where the first side wall is located to form a hot air chamber 110. The hot air baffle 11 includes a hot air inlet 111 located in the center and a hot air outlet 112 located on the side of the hot air inlet 111. A hot air blower 12 is installed on the first side wall of the inner liner 10, and the impeller 121 of the hot air blower 12 is located in the hot air chamber 110 and faces the hot air inlet 111.

[0046] Furthermore, it also includes an air chamber 30 located outside the inner liner 10, which has an air outlet 35, an air inlet 31, and a first air guide 32 communicating with the outside. The air outlet 35 is located on one side of the air chamber 30, while the air inlet 31 and the first air guide 32 are located on the other side of the air chamber 30, with the air inlet 31 and the first air guide 32 spaced apart. An exhaust port 101 is provided on the first side wall of the inner liner 10, located outside the horizontal projection of the impeller 121 on the first side wall. A second air guide 102, lower in height than the exhaust port 101 and located outside the hot air chamber 110, is also provided on the other side wall of the inner liner 10. Figure 10 As shown. Furthermore, the exhaust port 101 is in fluid communication with the air inlet 31, and the second air duct 102 is in fluid communication with the first air duct 32. The hot air blower 12 has at least a first rotational speed and a second rotational speed greater than the first rotational speed. Furthermore, during the dehumidification stage of the baking mode or in the state after cooking, the hot air blower 12 rotates at the second rotational speed, and the second air duct introduces outside air into the inner liner 10.

[0047] As can be seen from the above, the present invention provides exhaust ports 101 and second air guide ports 102 on different side walls of the inner liner 10. The exhaust port 101 is located in the hot air chamber 110 and is located outside the horizontal projection of the impeller 121 on the first side wall (the side wall of the inner liner 10 where the exhaust port 101 is located), while the second air guide port 102 is located outside the hot air chamber 110, and the height of the second air guide port 102 is lower than that of the exhaust port 101. In this way, during the dehumidification stage of the baking mode or in the state after cooking, the hot air blower 12 rotates at the second speed. The high-speed rotation of the hot air blower 12 causes hot air to accumulate at the exhaust port 101. The air pressure at the exhaust port 101 is greater than the atmospheric pressure, and the hot air enters the air chamber 30 through the air inlet 31 via the exhaust port 101. At this time, a negative pressure is formed at the first air inlet 32 ​​of the air chamber 30 relative to the air inlet 31, and the pressure is lower than atmospheric pressure. Cold air from the outside enters the air chamber 30 through the air outlet 35, and then enters the inner liner 10 through the second air inlet 102 on the inner liner 10 via the first air inlet 32. This forces the hot air in the inner liner 10 to flow upwards towards the exhaust outlet 101, creating a dual-path convection circulation effect in the inner liner 10 and the air chamber 30. This achieves strong exhaust of moisture during baking mode or strong exhaust of residual gas in the inner liner 10 after cooking. Compared with existing technologies, this invention does not require an additional blower at the second air inlet 102. The technical effect of forced exhaust can be achieved simply by designing the positions of the exhaust outlet 101 and the second air inlet 102 on different side walls of the inner liner 10, as well as the rotation speed of the hot air blower 12.

[0048] Furthermore, in this embodiment, during the dehumidification stage of the baking mode or at the end of cooking, the second rotation speed of the hot air blower 12 is 1700 r / min to 2100 r / min, which is beneficial for better forming a dual-path convection circulation effect. In addition, in this embodiment, the first rotation speed is 1000 r / min to 1300 r / min.

[0049] Furthermore, such as Figures 6-9 As shown, the stove 2 is equipped with a heat dissipation channel 23 to dissipate heat from electrical components (e.g., power board, display board, etc.) that generate heat during operation. The air chamber 30 also has an air inlet, which is fluidly connected to the heat dissipation outlet of the heat dissipation channel 23. In this way, during the dehumidification stage of the baking mode or when cooking is finished, the warm heat dissipation gas in the heat dissipation channel 23 can enter the air chamber 30 through the air inlet, and then mix with the exhaust airflow from the first air guide 32 and enter the inner pot 10. This prevents cold air from directly entering the inner pot 10 and affecting the temperature uniformity of the inner pot 10, and also prevents the cooked food placed in the inner pot 10 from cooling down.

[0050] Furthermore, the aforementioned air inlet includes a first air inlet 33 and a second air inlet 34 spaced apart, wherein the first air inlet 33 corresponds to the aforementioned exhaust port 101 and the second air inlet 34 corresponds to the aforementioned second air guide port 102. The first air inlet 33 is positioned at a height lower than the aforementioned air outlet 35 but higher than the aforementioned air inlet 31. The first air inlet 33 is located on one side of the air inlet 31, and the air intake direction of the first air inlet 33 faces the aforementioned air outlet 35. Moreover, the air intake direction of the first air inlet 33 intersects with the air intake direction of the aforementioned air inlet 31. In this way, the airflow entering the air chamber 30 through the first air inlet 33 can mix with the airflow entering through the air inlet 31, and accelerate the airflow towards the air outlet of the air chamber 30. The air inlet 35 accelerates the air intake speed of the air inlet 31, thereby accelerating the exhaust speed of the exhaust port 101 of the inner liner 10. The second air inlet 34 is positioned lower than the air outlet 35 but higher than the second air guide port 102. The second air inlet 34 is located on one side of the second air guide port 102, and its air intake direction is towards the second air guide port 102, intersecting with the air outlet direction of the second air inlet 34. In this way, the airflow entering the air chamber 30 through the second air inlet 34 mixes with the airflow exiting the air chamber 30 through the first air guide port 32, accelerating the exit of the airflow from the air chamber 30, thereby accelerating the exhaust speed of the second air guide port 102, and thus accelerating the air intake speed of the first air guide port 32 of the inner liner 10. Preferably, the airflow direction of the air inlet 31 and the second air guide 102 is both vertical, while the airflow direction of the first air inlet 33 and the second air inlet 34 is both horizontal. In this way, the airflow entering the air chamber 30 through the first air inlet 33 can better replenish the kinetic energy of the airflow entering through the air inlet 31, while the airflow entering through the second air inlet 34 has a downward vector, thereby better accelerating the airflow exiting through the first air guide 32.

[0051] Furthermore, the aforementioned stove 2 includes a base 21 with an upper portion and a panel 22 covering the opening of the base 21. An exhaust window 221 is provided on the rear side of the panel 22, and an exhaust cover 222 is installed within the exhaust window 221. The aforementioned gas chamber 30 is disposed within the stove 2, and the gas outlet 35 of the gas chamber 30 is in fluid communication with the exhaust window 221. This allows the gas entering the gas chamber 30 to be better discharged through the exhaust outlet 35, while also allowing outside air to enter the gas chamber 30 more effectively. Specifically, in this embodiment, the lower surface of the panel 22 is surrounded by rectangular gas boxes 3 along the left and right sides of the exhaust window 221 to form the gas chamber 30, and the upper opening of the gas box 3 constitutes the exhaust outlet 35. This effectively forms the structure of the gas chamber 30 and facilitates the connection between the exhaust outlet 35 of the gas chamber 30 and the exhaust window 221 of the panel 22.

[0052] Furthermore, the aforementioned air inlet 31 and the first air guide 32 are spaced apart on the bottom wall of the air box 3 in the left-right direction, while the aforementioned first air inlet 33 and the second air inlet 34 are on the front side wall of the air box 3 in the left-right direction, with the first air inlet 33 opposite to the aforementioned air inlet 31 and the second air inlet 34 opposite to the aforementioned second air guide 102.

[0053] Preferably, the first air inlet 33 faces upwards, so that when the cooling gas in the heat dissipation channel 23 enters the air chamber 30 through the first air inlet 33, it forms an upward airflow. When it mixes with the airflow at the air inlet 31, it can replenish the kinetic energy of the airflow without turning, and at the same time, it can guide the airflow to the air outlet 35 of the air chamber 30, improving the smoothness of air intake at the air inlet 31, and thus improving the smoothness of exhaust at the exhaust outlet 101. The second air inlet 34 faces downwards, so that the cooling gas in the heat dissipation channel 23 flows into the air chamber 30 from top to bottom, thereby better accelerating the gas to flow out of the air chamber 30 through the first air guide 32. The first air inlet 33 and the second air inlet 34 are both located on the front side wall of the air box 3. On the one hand, it facilitates the flow of heat dissipation gas in the heat dissipation channel 23 (which is arranged in front of the air box 3 in the front-back direction) into the first air inlet 33 and the second air inlet 34 respectively. On the other hand, it makes the air flow in each air path in the air chamber 30 more regular, avoiding collision and mixing and causing loss of air kinetic energy.

[0054] Furthermore, to achieve upward air intake at the first air inlet 33 and downward air intake at the second air inlet 34, in this embodiment, preferably, the edge of the first air inlet 33 is inclined upward from the outside to the inside relative to the air box 3, thereby achieving upward air intake at the first air inlet 33, while the edge of the second air inlet is inclined downward from the outside to the inside relative to the air box 3, thereby achieving downward air intake at the second air inlet 34. More preferably, the first air inlet 33 is formed by horizontally extending first air inlet holes 331 arranged vertically at intervals, and the channels of each first air inlet hole 331 are inclined upward from the outside to the inside relative to the air box 3, thereby allowing the heat dissipation gas to flow more smoothly upward into the air chamber 30 and better mix with the airflow from the air inlet 31. Accordingly, the second air inlet 34 is formed by horizontally extending second air inlet holes 341 arranged vertically at intervals, and the channels of each second air inlet hole 341 are inclined upward from the outside to the inside relative to the air box 3, so that the heat dissipation gas can flow downward into the air chamber 30 more smoothly, and better act on the exhaust airflow of the second air guide port 102.

[0055] Furthermore, the system also includes a water collection box 4 disposed within the aforementioned air box 3. The upper part of the water collection box 4 is open, forming a condensate outlet 43 that communicates vertically with the air outlet 35 of the air box 3. A first condensate outlet 41 and a second condensate outlet 42 are spaced apart and arranged side-by-side on the bottom wall of the water collection box 4. The first condensate outlet 41 is fluidly connected to the air inlet 31, while the second condensate outlet 42 is fluidly connected to the first air guide outlet 32. The first air inlet 33 and the second air inlet 34 are respectively located on the water collection box 4. By providing the water collection box 4, the condensate formed in the air box 3 can be collected, preventing condensate from flowing freely throughout the air box 3. In this embodiment, the first condensate outlet 41 is vertically aligned with and connected to the air inlet 31, and the second condensate outlet 42 is vertically aligned with and connected to the first air guide outlet 32. In this embodiment, preferably, an air guide sleeve 7 is vertically arranged on the inner bottom surface of the water collection box 4 outside the first condensing air port 41 and the second condensing air port 42, so as to avoid mutual interference of the airflow in the first condensing air port 41 and the second condensing air port 42, and ensure smooth air intake of the air inlet 31 and smooth air outlet of the first air guide port 32.

[0056] Furthermore, in this embodiment, preferably, the exhaust port 101 is located at the upper left end of the back sidewall of the inner liner 10 (i.e., the first sidewall is the back sidewall of the inner liner 10), while the second air guide port 102 is located at the lower rear end of the right sidewall of the inner liner 10. This allows for a better pressure differential between the exhaust port 101 and the second air guide port 102 during dual-path convection circulation, thus better ensuring the dual-path convection circulation effect. Preferably, the distance between the exhaust port 101 and the upper edge of the back sidewall of the inner liner 10 is less than or equal to 1 / 3 of the height of the back sidewall, which facilitates the upward movement of hot air and its accumulation at the exhaust port 101. Preferably, the distance between the second air guide port 102 and the lower edge of the right sidewall of the inner liner 10 is less than or equal to 1 / 3 of the height of the right sidewall, which facilitates the sinking of cold air at the first air guide port. Therefore, during dual-path convection circulation, the outside air entering through the first air guide port can better compress the hot air in the inner liner 10 towards the exhaust port 101.

[0057] Furthermore, the hot air outlet 112 of the aforementioned hot air baffle 11 includes a first hot air outlet 1121 located at the lower right corner of the hot air baffle 11, and the lowest point of the aforementioned second air guide 102 is higher than the lowest point of the first hot air outlet 1121. This allows the airflow from the first hot air outlet 1121 to converge with the outside air entering the inner liner 10 through the second air guide 102, thus enabling outside air to enter the inner liner 10 more quickly. Preferably, the first hot air outlet 1121 is composed of evenly spaced, elongated air outlets extending to the left and right, which facilitates the convergence of the airflow from the first hot air outlet 1121 with the airflow from the second air guide 102 at this location.

[0058] Furthermore, the exhaust port 101 is connected to the air inlet 31 via the exhaust pipe 5, and the second air guide port 102 is connected to the first air guide port 32 via the air guide pipe 6. The diameters of the exhaust pipe 5 and the air guide pipe 6 are both 8mm≤d≤12mm, which is beneficial for obtaining better exhaust effect in different cooking modes.

[0059] The term "fluid connectivity" as used in this invention refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber that allows fluid to flow through, or a combination of the above.
