Description

Technical Field

[0001] This invention relates to the field of stove technology, and in particular to a heat dissipation device and a stove. Background Technology

[0002] In the current market environment, the heat dissipation solution for the electronic components of the cooktop chassis of integrated cooktop, steam, and oven appliances often adopts a combination of independent centrifugal fans and specific heat dissipation channels to ensure that the heat dissipation performance meets design requirements. Specifically, the centrifugal fan is usually located in the upstream area of ​​the heat dissipation channel, while the air inlets for heat dissipation of the cooktop chassis are respectively located on the lower side panel of the upstream section and the front and rear side panels of the upstream and downstream sections, with smaller circular air inlets used near the electronic components and knobs.

[0003] The above design has significant drawbacks: 1. Due to the limited area of ​​the air inlet opening, less airflow passes through critical components such as electronic components and knobs, resulting in poor heat dissipation and locally higher temperatures. Prolonged exposure to this condition will accelerate component aging and negatively impact the overall lifespan of the cooktop chassis. 2. The spatial layout of the air inlet and fan lacks rational consideration. A large proportion of the heat dissipation airflow enters from the air inlet near the condensate tray, ensuring sufficient airflow in this area for adequate cooling of non-critical components. However, the airflow to areas containing critical components such as electronic components and knobs is relatively scarce, leading to insufficient cooling. Therefore, this unreasonable air inlet arrangement further weakens the overall heat dissipation efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of insufficient air flow and inadequate heat dissipation in the area where electronic components are located in the prior art, and to provide a heat dissipation device and stove.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This invention provides a heat dissipation device, which includes a housing, a fan drive section, and a condenser exhaust section. The housing has a receiving cavity and multiple air inlets that connect the receiving cavity to the outside. The fan drive section and the condenser exhaust section are both located within the receiving cavity.

[0007] The heat dissipation device further includes a heat dissipation air inlet section disposed in the receiving cavity. The heat dissipation air inlet section, the fan drive section and the condenser air outlet section are sequentially connected. The heat dissipation air inlet section is used to be disposed below the electronic components of the stove. The air inlet of the outer shell is disposed on the side of the outer shell near the heat dissipation air inlet section.

[0008] In this design, the housing cavity is equipped with a heat dissipation air inlet section, a fan drive section, and a condenser air outlet section, which are sequentially connected. The housing air inlet is located on the side of the housing closest to the heat dissipation air inlet section. Airflow enters the housing cavity from the outside through the housing air inlet, and then sequentially enters the heat dissipation air inlet section, the fan drive section, and the condenser air outlet section. The fan drive section provides driving force for the heat dissipation device, allowing airflow to flow into the heat dissipation device. After heat exchange, the airflow is finally discharged to the outside through the condenser air outlet section. By placing the heat dissipation air inlet section below the electronic components and placing the housing air inlet on the side of the housing closest to the heat dissipation air inlet section, the airflow guidance is enhanced, increasing the airflow rate passing over the electronic components and ensuring that the electronic components receive sufficient heat dissipation airflow coverage, thereby improving the heat dissipation effect.

[0009] Preferably, the heat dissipation air intake section is a heat dissipation box, the lower end of which is connected to the bottom plate of the outer shell, and the heat dissipation box is provided with an air intake chamber;

[0010] The heat sink box is provided with a plurality of heat dissipation air inlets that connect the receiving cavity and the air inlet cavity. The heat dissipation air inlets include a first air inlet located on the top surface of the heat sink box, which is positioned below the electronic components.

[0011] In this solution, the air in the containment cavity enters the air intake cavity of the heat sink box through the heat dissipation air intake hole. The heat dissipation air intake hole includes a first air intake hole located on the top surface of the heat sink box. The first air intake hole is located below the electronic components. The air in the containment cavity flows through the electronic components before flowing into the first air intake hole, thereby increasing the airflow through the electronic components and improving the heat dissipation effect on the electronic components.

[0012] Preferably, the first air inlet is a strip-shaped hole, and the length of the strip-shaped hole is consistent with the maximum width of the electronic component;

[0013] And / or, the area of ​​the first air inlet hole accounts for 50%-60% of the total area of ​​the heat dissipation air inlet holes.

[0014] In this solution, by setting the first air inlet as a strip-shaped hole and making the length of the strip-shaped hole consistent with the width of the electronic components, the strip-shaped hole can fully cover the electronic components, ensuring the heat dissipation effect of the electronic components. The shape of the strip-shaped hole can avoid the airflow in other areas of the stove chassis from adversely interfering with the airflow organization inside the heat dissipation box, and prevent a large amount of non-target airflow from rushing into the heat dissipation box and destroying its heat dissipation efficiency.

[0015] Given that the heat dissipation requirements of electronic components are significantly higher than those of other areas, i.e., the heat dissipation air volume required by electronic components accounts for about 50%-60% of the total heat dissipation air volume of the stove chassis, the area of ​​the first air inlet is set to account for 50%-60% of the total area of ​​the heat dissipation air inlet, so as to achieve reasonable distribution and optimized utilization of heat dissipation air volume.

[0016] Preferably, the heat dissipation air inlet further includes a plurality of second air inlets, which are disposed on both sides of the first air inlet, and the second air inlets are used to house the knobs of the stove.

[0017] And / or, the area of ​​the second air inlet vent accounts for 20%-25% of the total area of ​​the heat dissipation air inlet vents;

[0018] And / or, the length of the heat sink box satisfies X1≤L<X2, where X1 is the distance between the two knobs and X2 is the distance between the burners of the two stoves; the width of the heat sink box satisfies d1≤D≤d2, where d1 is the width of the electronic component and d2 is the distance between the center of the fan of the fan drive section and the side wall of the outer casing near the heat sink box.

[0019] In this design, the two knobs on the stove base are essential switches that are touched by the human body. The knobs are usually located on both sides of the electronic components. By setting a second air inlet and placing the knobs inside the second air inlet, there is a gap between the knobs and the second air inlet for air to flow in. When air flows in from the second air inlet, the air will flow through the knobs, thereby enhancing the heat dissipation effect on the knobs.

[0020] By setting the area of ​​the second air inlet to account for 20%-25% of the total area of ​​the heat dissipation air inlet, the air flowing in from the second air inlet is within a suitable range to match the heat dissipation requirements of the knob area.

[0021] By ensuring that the length of the heat sink meets X1≤L<X2 and the width meets d1≤D≤d2, the heat sink can fully cover the electronic components and knob area, ensuring the heat dissipation effect of these areas, while avoiding the impact of an excessively large heat sink on other components such as the stove head.

[0022] Preferably, the heat dissipation air inlet further includes a third air inlet, which is directed toward the burner of the stove, and the third air inlet has a triangular prism-shaped cut structure;

[0023] And / or, the area of ​​the third air inlet occupies 10%-20% of the total area of ​​the heat dissipation air inlets.

[0024] In this design, a third air inlet facing the burner head enhances heat dissipation. By designing this third air inlet with a triangular prism-shaped cut, airflow is introduced in three dimensions, achieving comprehensive heat dissipation for the burner head. Furthermore, by setting the area of ​​the third air inlet to 10%-20% of the total area of ​​the heat dissipation air inlets, the airflow entering from the third air inlet is kept within a suitable range to match the heat dissipation needs of the burner area.

[0025] Preferably, the heat dissipation air inlet further includes a fourth air inlet, which is directed toward the igniter of the stove;

[0026] And / or, the area of ​​the fourth air inlet occupies 5%-10% of the total area of ​​the heat dissipation air inlets.

[0027] In this design, a fourth air inlet facing the igniter enhances heat dissipation. By setting the area of ​​the fourth air inlet to 5%-10% of the total area of ​​the heat dissipation air inlets, the airflow from the third air inlet is kept within a suitable range to match the heat dissipation needs of the igniter area.

[0028] Preferably, the heat dissipation box is provided with a heat dissipation outlet that connects the air inlet chamber and the fan drive section, and the area of ​​the heat dissipation outlet is smaller than the total area of ​​the heat dissipation inlet.

[0029] In this solution, by setting the area of ​​the heat dissipation exhaust vents to be smaller than the total area of ​​the heat dissipation intake vents, the incoming air can be gradually accelerated, making the airflow smoother and further improving the heat dissipation effect.

[0030] Preferably, the fan drive section is located in the middle of the width direction of the housing, or on the side of the housing near the condenser outlet section.

[0031] In this solution, by placing the fan drive section in the middle of the width of the housing, or on the side of the housing near the condenser exhaust section, sufficient space is provided on the side near the electronic components to accommodate the heat dissipation intake section, thus extending the airflow path and enabling the electronic components to dissipate heat effectively.

[0032] Preferably, the heat dissipation device further includes a transition flow channel section, wherein the heat dissipation air inlet section and the fan drive section are connected through the two ends of the transition flow channel section.

[0033] In this solution, by setting up a transition flow channel connecting the heat dissipation air intake section and the fan drive section, the airflow of the heat dissipation air intake section can be gradually guided to the fan drive section, optimizing the airflow path and further improving the heat dissipation effect.

[0034] Preferably, the aspect ratio of the cross-section of the transition channel section decreases gradually from the air inlet to the air outlet along the direction of the air inlet.

[0035] In this design, by gradually decreasing the width-to-height ratio of the cross-section of the transition channel section from the inlet to the outlet along the transition channel section, the airflow can be guided to accelerate and its flow characteristics can be improved, thereby further enhancing the heat dissipation effect.

[0036] Preferably, the fan drive section includes a fan and a fan inlet box. The fan inlet box is provided with a fan inlet chamber. The inlet of the fan inlet chamber is connected to the outlet of the transition flow channel section, and the outlet of the fan inlet chamber is connected to the inlet of the fan.

[0037] In this design, the airflow flows from the outlet of the transition channel section into the fan inlet chamber, and then from the fan inlet chamber into the fan. By setting up the fan inlet chamber, a transition function is provided, which reduces airflow loss and optimizes the airflow path.

[0038] Preferably, the cross-sectional area of ​​the air outlet of the fan inlet chamber is larger than the cross-sectional area of ​​the fan inlet;

[0039] And / or, the side of the fan inlet box connected to the air outlet of the transition flow channel section is a rectangular structure, and the side of the fan inlet box connected to the air inlet of the fan is an arc-shaped structure.

[0040] In this solution, by making the cross-sectional area of ​​the air outlet of the fan inlet chamber larger than the cross-sectional area of ​​the fan inlet, it is ensured that the fan inlet chamber can fully cover and surround the fan's air intake area, thereby effectively preventing airflow leakage and reducing energy loss caused by leakage.

[0041] By setting the side connecting the fan inlet box to the outlet of the transition flow channel section as a rectangular structure and the side connecting the fan inlet box to the fan inlet as an arc-shaped structure, a transitional structural design from a rectangular cross section to an arc-shaped cross section is achieved, optimizing the airflow path and reducing flow resistance.

[0042] Preferably, the fan inlet box is located above the fan;

[0043] The transition flow channel section includes a first part, a second part, and a third part, which are arranged sequentially along the direction from the air inlet to the air outlet of the transition flow channel section.

[0044] Along the direction from the air inlet to the air outlet of the transition flow channel section, the second part extends obliquely upward, and the width of the second part gradually decreases.

[0045] In this design, the airflow passes sequentially through the first, second, and third sections before flowing into the fan inlet chamber. The fan inlet box is located above the fan, extending from the inlet to the outlet along the transition flow channel section. By extending the second section upwards at an angle, the airflow is guided to the upper fan inlet box. The width of the second section is gradually reduced to accelerate the airflow and improve its flow characteristics.

[0046] Preferably, the housing air inlet includes multiple electronic component air inlets, which are disposed on the side wall of the housing near the first air inlet, and are configured to be close to the electronic components.

[0047] And / or, the heat dissipation air inlet further includes a plurality of second air inlets, the plurality of second air inlets being disposed on both sides of the first air inlet, the second air inlets being used to house the knob of the stove, the outer shell air inlet further includes a knob air inlet, the knob air inlet being disposed on the side wall of the outer shell near the second air inlet, the knob air inlet being configured to be close to the knob;

[0048] And / or, the housing air inlet further includes an auxiliary air inlet, which is located on both sides of the length direction of the housing and on the side of the housing closer to the heat dissipation device. The area of ​​the auxiliary air inlet is larger than the area of ​​the knob air inlet.

[0049] In this design, by placing an air inlet near the first air inlet on the electronic components, airflow is made easier to pass through the electronic components, thus increasing the heat dissipation effect. Similarly, by placing an air inlet near the second air inlet on the knob, airflow is made easier to pass through the knob, thus increasing the heat dissipation effect.

[0050] By incorporating auxiliary air inlets on both sides of the outer casing along its length, heat dissipation for other components within the cooktop, such as the burner and igniter, is enhanced. Furthermore, the auxiliary air inlets have a larger area than the knob air inlet, resulting in a greater airflow. In addition to meeting the heat dissipation needs of other components, some airflow will also enter through the heat dissipation vents of the heat sink, further strengthening the heat dissipation effect on electronic components.

[0051] The present invention also provides a stove, which includes the aforementioned heat dissipation device.

[0052] The positive and progressive effects of this invention are as follows:

[0053] The housing cavity is equipped with a heat dissipation air inlet section, a fan drive section, and a condenser air outlet section, which are sequentially connected. The housing air inlet is located on the side of the housing closest to the heat dissipation air inlet section. Airflow enters the housing cavity from the outside through the housing air inlet, and then sequentially enters the heat dissipation air inlet section, the fan drive section, and the condenser air outlet section. The fan drive section provides driving force for the heat dissipation device, allowing airflow to flow into the heat dissipation device. After heat exchange, the airflow is finally discharged to the outside through the condenser air outlet section. By placing the heat dissipation air inlet section below the electronic components and placing the housing air inlet on the side of the housing closest to the heat dissipation air inlet section, the airflow guidance is enhanced, increasing the airflow volume passing over the electronic components and ensuring that the electronic components receive sufficient heat dissipation airflow coverage, thereby improving the heat dissipation effect.

[0092] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the following embodiments.

[0093] like Figure 1 and Figure 2 As shown, this embodiment provides a type of stove 100, which includes a heat dissipation device 300.

[0094] like Figures 3-8 As shown, the heat dissipation device 300 includes a housing 200, a fan drive section 500, and a condenser exhaust section 600. The housing 200 has a receiving cavity 210 and multiple housing air inlets 220 connecting the receiving cavity 210 to the outside. The fan drive section 500 and the condenser exhaust section 600 are both located within the receiving cavity 210. The heat dissipation device 300 also includes a heat dissipation air inlet section 400 located within the receiving cavity 210. The heat dissipation air inlet section 400, the fan drive section 500, and the condenser exhaust section 600 are sequentially connected. The heat dissipation air inlet section 400 is positioned below the electronic components of the stove 100, and the housing air inlets 220 are located on the side of the housing 200 near the heat dissipation air inlet section 400.

[0095] The housing 200 has a heat dissipation air inlet section 400, a fan drive section 500 and a condenser air outlet section 600 inside its accommodating cavity 210. The heat dissipation air inlet section 400, the fan drive section 500 and the condenser air outlet section 600 are connected in sequence. The housing air inlet 220 is located on the side of the housing 200 near the heat dissipation air inlet section 400. Airflow enters the accommodating cavity 210 from the outside through the housing air inlet 220, and then enters the heat dissipation air inlet section 400, the fan drive section 500 and the condenser air outlet section 600 in sequence. The fan drive section 500 provides driving force for the heat dissipation device 300, allowing airflow to flow into the heat dissipation device 300. After heat exchange, the airflow is finally discharged to the outside through the condenser exhaust section 600. By placing the heat dissipation air inlet section 400 below the electronic components and placing the housing air inlet 220 on the side of the housing 200 close to the heat dissipation air inlet section 400, the airflow is guided more effectively, the airflow rate passing through the electronic components is increased, and the electronic components are ensured to receive sufficient heat dissipation airflow coverage, thereby increasing the heat dissipation effect.

[0096] The heat dissipation air intake section 400 is a heat sink 410. The lower end of the heat sink 410 is connected to the bottom plate of the outer casing 200. The bottom plate of the outer casing 200 has a groove that matches the shape of the lower end of the heat sink 410. The lower end of the heat sink 410 is detachably connected to the groove. The heat sink 410 has an air intake chamber 411. The heat sink 410 has multiple heat dissipation air intake holes 420 that connect the receiving chamber 210 and the air intake chamber 411. The heat dissipation air intake hole 420 includes a first air intake hole 421 located on the top surface of the heat sink 410. The first air intake hole 421 is positioned below the electronic components. In this embodiment, the heat sink 410 is square. In other embodiments, the heat sink 410 may also be any other shape that is deemed suitable by those skilled in the art.

[0097] like Figure 3As shown, air in the receiving cavity 210 enters the air intake cavity 411 of the heat sink 410 through the heat dissipation air inlet 420. The heat dissipation air inlet 420 includes a first air inlet 421 located on the top surface of the heat sink 410. The first air inlet 421 is located below the electronic components. Before the air in the receiving cavity 210 flows into the first air inlet 421, it flows through the electronic components, increasing the airflow through the electronic components and improving the heat dissipation effect on the electronic components.

[0098] The first air inlet 421 is a strip-shaped hole, the length of which is consistent with the maximum width of the electronic component. By setting the first air inlet 421 as a strip-shaped hole and matching its length with the width of the electronic component, the strip-shaped hole can fully cover the electronic component, ensuring effective heat dissipation. The shape of the strip-shaped hole also prevents airflow from other areas of the stove 100 chassis from adversely interfering with the airflow organization inside the heat sink 410, and prevents a large amount of non-target airflow from entering the heat sink 410 and compromising its heat dissipation efficiency.

[0099] The area of ​​the first air inlet 421 accounts for 50%-60% of the total area of ​​the heat dissipation air inlet 420. Given that the heat dissipation requirements of electronic components are significantly higher than those of other areas, that is, the heat dissipation air volume required by electronic components accounts for about 50%-60% of the total heat dissipation air volume of the stove 100 chassis, by setting the area of ​​the first air inlet 421 to account for 50%-60% of the total area of ​​the heat dissipation air inlet 420, the heat dissipation air volume is rationally distributed and optimized.

[0100] The heat dissipation air inlet 420 also includes multiple second air inlets 422, which are located on both sides of the first air inlet 421. The second air inlets 422 are used to house the knobs 120 of the cooktop 100. The two knobs 120 on the base of the cooktop 100 are essential switches touched by the human body. Knobs 120 are usually located on both sides of electronic components. By setting up the second air inlets 422 and placing the knobs 120 inside the second air inlets 422, there is a gap between the knobs 120 and the second air inlets 422 for air to flow in. When air flows in from the second air inlets 422, the air will flow through the knobs 120, thereby enhancing the heat dissipation effect on the knobs 120.

[0101] The area of ​​the second air inlet 422 accounts for 20%-25% of the total area of ​​the heat dissipation air inlet 420. By setting the area of ​​the second air inlet 422 to account for 20%-25% of the total area of ​​the heat dissipation air inlet 420, the air flowing in from the second air inlet 422 is within a suitable range to match the heat dissipation requirements of the knob 120 area.

[0102] The length of the heat dissipation box 410 satisfies X1≤L<X2, where X1 is the distance between the two knobs 120 and X2 is the distance between the burners 110 of the two stoves 100. The width of the heat dissipation box 410 satisfies d1≤D≤d2, where d1 is the width of the electronic components and d2 is the distance between the center of the fan 510 of the fan drive section 500 and the side wall of the outer casing 200 near the heat dissipation box 410. By satisfying X1≤L<X2 for the length of the heat dissipation box 410 and d1≤D≤d2 for the width, the heat dissipation box 410 can fully cover the areas of the electronic components and knobs 120, ensuring the heat dissipation effect in these areas, while avoiding the impact of an excessively large heat dissipation box 410 on other components such as the burners 110.

[0103] The heat dissipation air inlet 420 also includes a third air inlet 423, which faces the burner 110 of the cooktop 100. The third air inlet 423 has a triangular prism-shaped cut structure. By setting a third air inlet facing the burner 110 of the cooktop 100, the heat dissipation effect on the burner 110 can be enhanced. By setting the third air inlet 423 to a triangular prism-shaped cut structure, air can be introduced in three dimensions, achieving all-round heat dissipation for the burner 110. In this embodiment, the third air inlet 423 is located at two corners of the heat dissipation box 410, facing the two burners 110 of the cooktop 100.

[0104] The area of ​​the third air inlet 423 accounts for 10%-20% of the total area of ​​the heat dissipation air inlet 420. By setting the area of ​​the third air inlet 423 to account for 10%-20% of the total area of ​​the heat dissipation air inlet 420, the airflow from the third air inlet 423 is within a suitable range to match the heat dissipation requirements of the burner head 110 area.

[0105] The heat dissipation air inlet 420 also includes a fourth air inlet 424, which is directed toward the igniter 130 of the cooktop 100. By providing the fourth air inlet 424 toward the igniter 130 of the cooktop 100, the heat dissipation effect on the igniter 130 can be enhanced.

[0106] The area of ​​the fourth air inlet 424 accounts for 5%-10% of the total area of ​​the heat dissipation air inlet 420. By setting the area of ​​the fourth air inlet 424 to account for 5%-10% of the total area of ​​the heat dissipation air inlet 420, the airflow from the third air inlet 423 is within a suitable range to match the heat dissipation requirements of the igniter 130 area.

[0107] The heat sink 410 is provided with a heat dissipation outlet 430 that connects the air intake chamber 411 and the fan drive section 500. The area of ​​the heat dissipation outlet 430 is smaller than the total area of ​​the heat dissipation inlet 420. By setting the area of ​​the heat dissipation outlet 430 to be smaller than the total area of ​​the heat dissipation inlet 420, the incoming air can be gradually accelerated, making the airflow smoother and further improving the heat dissipation effect.

[0108] The fan drive section 500 is located in the middle of the width direction of the housing 200, or on the side of the housing 200 near the condenser exhaust section 600. By placing the fan drive section 500 in the middle of the width direction of the housing 200, or on the side of the housing 200 near the condenser exhaust section 600, sufficient space is provided on the side near the electronic components to accommodate the heat dissipation air inlet section 400, extending the airflow path and enabling the electronic components to dissipate heat effectively.

[0109] like Figure 4 and Figure 5 As shown, the heat dissipation device 300 also includes a transition flow channel section 700, through which the heat dissipation air inlet section 400 and the fan drive section 500 are connected. By setting the transition flow channel section 700 connecting the heat dissipation air inlet section 400 and the fan drive section 500, the airflow of the heat dissipation air inlet section 400 can be gradually guided to the fan drive section 500, optimizing the airflow path and further improving the heat dissipation effect.

[0110] Along the direction from the air inlet to the air outlet of the transition flow channel section 700, the aspect ratio of the cross-section of the transition flow channel section 700 decreases step by step. By gradually decreasing the aspect ratio of the cross-section of the transition flow channel section 700 along the direction from the air inlet to the air outlet, the airflow can be guided to accelerate and its flow characteristics can be improved, thereby further enhancing the heat dissipation effect.

[0111] like Figure 6 and Figure 7 As shown, the fan drive section 500 includes a fan 510 and a fan inlet box 520. The fan inlet box 520 has a fan inlet chamber 521. The inlet of the fan inlet chamber 521 is connected to the outlet of the transition flow channel section 700, and the outlet of the fan inlet chamber 521 is connected to the inlet of the fan 510. Airflow flows from the outlet of the transition flow channel section 700 into the fan inlet chamber 521, and then from the fan inlet chamber 521 into the fan 510. By setting up the fan inlet chamber 521, a transition function is provided, reducing airflow loss and optimizing the airflow path.

[0112] The cross-sectional area of ​​the outlet of the fan inlet chamber 521 is larger than the cross-sectional area of ​​the inlet of the fan 510. By making the cross-sectional area of ​​the outlet of the fan inlet chamber 521 larger than the cross-sectional area of ​​the inlet of the fan 510, it is ensured that the fan inlet chamber 521 can fully cover and surround the air intake area of ​​the fan 510, thereby effectively preventing airflow leakage and reducing energy loss caused by leakage.

[0113] The side of the fan inlet box 520 that connects to the outlet of the transition flow channel section 700 has a rectangular structure, while the side of the fan inlet box 520 that connects to the inlet of the fan 510 has an arc-shaped structure. By making the side of the fan inlet box 520 that connects to the outlet of the transition flow channel section 700 a rectangular structure and the side of the fan inlet box 520 that connects to the inlet of the fan 510 an arc-shaped structure, a transitional structural design from a rectangular cross-section to an arc-shaped cross-section is achieved, optimizing the airflow path and reducing flow resistance.

[0114] like Figure 6 As shown, the fan inlet box 520 is located above the fan 510. The transition flow channel section 700 includes a first part 710, a second part 720, and a third part 730. Along the direction from the inlet to the outlet of the transition flow channel section 700, the first part 710, the second part 720, and the third part 730 are arranged sequentially. Along the direction from the inlet to the outlet of the transition flow channel section 700, the second part 720 extends obliquely upwards, and the width of the second part 720 gradually decreases. The airflow sequentially flows through the first part 710, the second part 720, and the third part 730 before flowing into the fan inlet chamber 521. The fan inlet box 520 is located above the fan 510. Along the direction from the air inlet to the air outlet of the transition flow channel section 700, the second part 720 is extended upward at an angle to guide the airflow to the fan inlet box 520 located above. The width of the second part 720 is gradually reduced to guide the airflow to accelerate and improve its flow characteristics.

[0115] like Figure 8 As shown, the housing air inlet 220 includes multiple electronic component air inlets 221, which are located on the side wall of the housing 200 near the first air inlet 421. The electronic component air inlets 221 are positioned close to the electronic components. By positioning the electronic component air inlets 221 close to the first air inlet 421, airflow is made easier to pass through the electronic components, increasing the heat dissipation effect on the electronic components.

[0116] The heat dissipation air inlet 420 also includes multiple second air inlets 422, which are located on both sides of the first air inlet 421. The second air inlets 422 are used to house the knob 120 of the cooktop 100. The outer casing air inlet 220 also includes a knob air inlet 222, which is located on the side wall of the outer casing 200 near the second air inlets 422. The knob air inlet 222 is positioned close to the knob 120. By positioning the knob air inlet 222 close to the second air inlets 422, airflow can more easily pass through the knob 120, increasing the heat dissipation effect on the knob 120.

[0117] The outer casing air inlet 220 also includes auxiliary air inlets 223, which are located on both sides of the outer casing 200 along its length, with the auxiliary air inlets 223 positioned on the side of the outer casing 200 closest to the heat dissipation device 300. The area of ​​the auxiliary air inlets 223 is larger than that of the knob air inlet 222. By providing auxiliary air inlets 223 on both sides of the outer casing 200 along its length, heat dissipation for other components within the cooktop 100, such as the burner 110 and igniter 130, is enhanced. Simultaneously, the larger area of ​​the auxiliary air inlets 223 allows for a greater airflow, ensuring sufficient heat dissipation for other components. Additionally, some airflow will enter through the heat dissipation air inlets 420 of the heat dissipation box 410, further enhancing the heat dissipation effect on electronic components.

[0118] The cooktop 100 has an intelligent voice control module, which includes a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the cooktop 100 to perform corresponding operations, thereby realizing the intelligent control of the cooktop 100 and improving the user experience of using this intelligent appliance.
