Description

Technical Field

[0001] The present invention relates to the field of stoves, and in particular to an integrated cooking stove. Background Art

[0002] An integrated cooking stove is a stove that integrates a stove (mainly a gas stove) and a cooking device (such as a steamer, oven, or a steam-bake combination). For example, the Chinese invention patent application number CN201910090198.X (publication number CN111503671A) discloses an integrated stove with a cooking device, comprising a cooking device having a cooking chamber and a stove arranged on top of the cooking device. The stove comprises a stove shell, an inner cavity of which is installed electronic components that generate heat during operation, and a heat dissipation system comprising a heat dissipation channel arranged in the inner cavity of the stove shell and a fan arranged in the heat dissipation channel. The heat dissipation channel has an air outlet port communicating with the outside world, and a first ventilation port communicating with the air inlet of the fan is provided on a first side wall of the stove shell.

[0003] While installing a heat dissipation system within the cooktop housing can improve heat dissipation for the cooktop's electrical components (such as the power board and display panel), and the exhaust duct above the cooking unit also effectively dissipates heat from the cooking unit, the placement of the cooktop above the cooking unit compresses the installation space for the cooking unit, thus compromising heat dissipation during operation. Furthermore, the exhaust ducts of existing cooking units typically face forward, blowing hot gases directly onto the user, impacting the user experience. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide an integrated cooking stove with good heat dissipation effect in view of the existing technology.

[0005] The second technical problem to be solved by the present invention is to provide an integrated cooking stove that can prevent the exhaust gas from directly spraying onto the user in response to the existing technology.

[0006] The technical solution adopted by the present invention to solve at least one of the above technical problems is as follows: an integrated cooking stove, comprising a cooking device and a stove arranged on the cooking device, the cooking device comprising a box body and an inner pot arranged in the box body, an upper mounting plate being horizontally arranged above the inner pot, the stove comprising a stove shell, the stove shell comprising a bottom plate with an upper opening and a panel covering the opening of the bottom plate, an exhaust window being provided on the rear side of the panel, and a first heat dissipation channel with a heat dissipation fan being provided in the bottom plate, a first heat dissipation outlet of the first heat dissipation channel being fluidly connected to the exhaust window The passage is characterized in that a heat dissipation interlayer communicated with the outside world is formed between the upper surface of the upper mounting plate of the cooking device and the bottom surface of the chassis of the stove shell, and the above-mentioned heat dissipation fan is arranged on the first heat dissipation air inlet of the first heat dissipation channel, and the above-mentioned heat dissipation fan includes a fan cavity and an impeller installed in the fan cavity, and the impeller includes an upper impeller and a lower impeller. Correspondingly, an upper air inlet corresponding to the upper impeller and a lower air inlet corresponding to the lower impeller are respectively provided on the above-mentioned fan cavity, and the upper air inlet is communicated with the inner cavity of the stove shell, and the lower air inlet is communicated with the above-mentioned heat dissipation interlayer through a through hole provided on the bottom wall of the chassis.

[0007] Furthermore, a second heat dissipation channel is provided in the heat dissipation interlayer. The second heat dissipation inlet of the second heat dissipation channel communicates with the outside world, while the second heat dissipation outlet communicates with the lower air inlet of the fan chamber via the aforementioned through hole. The provision of the second heat dissipation channel can guide the airflow in the heat dissipation interlayer, thereby improving the heat dissipation efficiency of the hot air in the heat dissipation interlayer.

[0008] Furthermore, the heat dissipation interlayer has a first vent on its front side, and the second heat dissipation channel is arranged in a front-to-back direction. The second heat dissipation inlet of the second heat dissipation channel is located at its front end and is in fluid communication with the first vent. Integrated cooking stoves are typically embedded in a cabinet, so locating the first vent at the front side improves the efficiency of cool air entering the second heat dissipation channel through the first vent.

[0009] Furthermore, a second air scoop is provided on the upper surface of the upper mounting plate. The second air scoop and the upper surface of the upper mounting plate define the second heat dissipation channel, and the second heat dissipation outlet is provided on the top wall of the second air scoop, vertically opposite the through hole. The second air scoop forms a stable second heat dissipation channel structure, and the second heat dissipation outlet on the top wall of the second air scoop accelerates the efficiency of gas in the second heat dissipation channel entering the heat dissipation fan, thereby improving the heat dissipation efficiency of the heat dissipation interlayer.

[0010] Furthermore, the stove also includes a third electrical component that generates heat during operation, and the cooking device also includes a water tank disposed on one side of the inner pot. An upper mounting space communicating with the heat dissipation interlayer is formed above the water tank, and the third electrical component is mounted in the upper mounting space, while the second heat dissipation channel has a heat dissipation air inlet communicating with the upper mounting space. The water contained in the water tank has a large specific heat, so the air temperature in the upper mounting space above it is relatively low. Placing the third electrical component in the upper mounting space with a lower temperature can dissipate heat for the third electrical component, thereby preventing the ambient temperature from being too high when the third electrical component is operating. The heated air in the upper mounting space can be drawn into the second heat dissipation channel through the heat dissipation air inlet, and then discharged into the heat dissipation fan through the lower air inlet, thereby further improving the heat dissipation effect for the third electrical component.

[0011] Furthermore, the second heat dissipation channel is arranged in parallel with the upper portion of the upper mounting space, and the heat dissipation air inlets are provided on a side of the second heat dissipation channel adjacent to the upper mounting space. There are at least two heat dissipation air inlets spaced apart from each other, and each heat dissipation air inlet is openable and closable. This improves the heat dissipation efficiency of the warm air in the upper mounting space, and the heat dissipation air inlets can be opened and closed according to heat dissipation needs. For example, when the temperature of the third electrical component is relatively high, the number of heat dissipation air inlets in the open state exceeds the number of heat dissipation air inlets in the closed state, while when the temperature of the third electrical component is relatively low, the number of heat dissipation air inlets in the closed state exceeds the number of heat dissipation air inlets in the open state.

[0012] Furthermore, the heat dissipation air inlets are spaced apart along the extension direction of the sidewall of the second air duct, and each heat dissipation air inlet is provided with an air inlet connector, the air inlet port of each air inlet connector being located in the upper mounting space. This allows warm air in the upper mounting space to enter the second heat dissipation channel more evenly and quickly for discharge, further improving the heat dissipation effect and efficiency for the third electrical component.

[0013] Furthermore, the rear end of the second heat dissipation channel is provided with a third heat dissipation inlet that is openable and closable, communicating with the outside world. This allows cool air from the outside to enter the second heat dissipation channel through the third heat dissipation inlet and, driven by the negative pressure at the second heat dissipation outlet, rapidly flow, further enhancing the heat dissipation effect on the heat dissipation interlayer and the third electrical component. When only the cooking device is in operation, the aforementioned heat dissipation inlets can be closed, while the third heat dissipation inlet is opened. The cool air entering through the third heat dissipation inlet dissipates heat from the third electrical component. Furthermore, the third heat dissipation inlet eliminates the need for a separate heat dissipation fan at the rear end of the heat dissipation channel, simplifying the internal structure of the integrated cooking stove and reducing production costs.

[0014] Furthermore, the third heat dissipation air inlet is provided on the rear end wall of the second air guide cover, and a second vent is provided on the rear side panel of the cooking device housing, the second vent being in fluid communication with the third heat dissipation air inlet, thereby allowing external cold air to enter the second heat dissipation channel more smoothly.

[0015] Furthermore, the stove further includes a first electrical component disposed in the chassis and generating heat during operation, the first electrical component being disposed vertically opposite to the third heat dissipation air inlet so that the cold air entering through the third heat dissipation air inlet can simultaneously dissipate heat from the first electrical component.

[0016] Furthermore, the first electrical component is mounted on the inner bottom surface of the chassis, and the top wall of the rear end of the second air duct is raised upward to form a heat dissipation boss. The top surface of the heat dissipation boss is a heat dissipation plane, which is in vertical contact with the outer bottom surface of the chassis where the first electrical component is located. The third heat dissipation inlet is provided on the rear side wall of the heat dissipation boss. In this way, the cold air entering through the third heat dissipation inlet is collected in the inner cavity of the heat dissipation boss, and is fully heat-exchanged with the heat generated by the first electrical component through the heat dissipation plane and the bottom wall of the chassis, further enhancing the heat dissipation effect on the first electrical component.

[0017] Furthermore, the first vents are formed along the left and right sides of the heat dissipation interlayer, while the cross-section of the second air guide increases from back to front. The second heat dissipation outlet is formed between the second and third heat dissipation inlets. This allows the cold air entering through the second and third heat dissipation inlets to fully exchange heat with the hot air in the heat dissipation interlayer (including the hot air entering the heat dissipation interlayer from the upper installation space), and the mixed air at both ends can be smoothly discharged through the second heat dissipation outlet.

[0018] Furthermore, the first side wall of the second air scoop extends in the front-to-back direction, the heat dissipation air inlets are spaced apart along the length of the first side wall, and the second side wall of the second air scoop includes, from back to front, a first wall, a second wall, and a third wall connected end to end. The first wall is inclined outward from back to front, the second wall extends in the left-right direction, and the third wall extends outward from back to front. The second heat dissipation air outlet is located on the front side of the second wall. This allows the hot air entering the heat dissipation air inlet to fully mix with the cold air entering the second heat dissipation channel. Furthermore, the first wall and the third wall can reduce the gas flow rate at the front and rear ends of the second heat dissipation channel, respectively. The second wall can further reduce the air flow rate flowing to the second heat dissipation air outlet, so that the fully mixed and heated mixed gas can be concentrated and discharged at the second heat dissipation air outlet.

[0019] Furthermore, the opening area of ​​the second heat dissipation inlet is larger than that of the third heat dissipation inlet. Accordingly, the inclination angle of the third wall relative to the front-to-back direction is larger than that of the first wall. This allows the cold air entering through the second and third heat dissipation inlets to fully and evenly exchange heat with the hot air, further improving the heat dissipation effect.

[0020] Furthermore, the stove also includes a second electrical component installed in the stove housing and generating heat during operation, and the upper air inlet of the fan cavity is adjacent to the second electrical component, thereby improving the heat dissipation effect of the first heat dissipation channel on the second electrical component.

[0021] Furthermore, the first heat dissipation channel is arranged along the front-to-back direction, and its height relative to the inner bottom surface of the chassis increases gradually from the first heat dissipation air inlet to the first heat dissipation air outlet. The fan outlet of the heat dissipation fan faces the first heat dissipation air outlet. This reduces wind resistance in the first heat dissipation channel, allowing the air in the first heat dissipation channel to be discharged more quickly, thereby improving heat dissipation efficiency.

[0022] Furthermore, an exhaust cavity is provided at the rear side of the interior of the range housing, comprising an exhaust outlet fluidly connected to the exhaust window and an exhaust inlet fluidly connected to the first heat dissipation outlet of the first heat dissipation channel. This prevents gas exhausted from the first heat dissipation channel from scattering within the range housing, thereby improving the heat dissipation efficiency of the first heat dissipation channel and preventing any impact on combustion of the stove burner.

[0023] Furthermore, the stove shell further includes a first air duct and a fan cover disposed in the chassis of the stove shell along the front and rear sides. The first air duct is in the shape of a sleeve, and its inner cavity forms the first heat dissipation channel. The fan cover is disposed on the inner bottom surface of the chassis where the through hole is located, and together with the inner bottom surface of the chassis, forms the fan cavity. The rear end of the fan cover is open to form a fan outlet, the top wall of the fan cover is open to form an upper air inlet, and the lower end of the fan cover forms the lower air inlet. The front end of the first air duct serves as the first heat dissipation inlet of the first heat dissipation channel, while the rear end serves as the first heat dissipation outlet of the first heat dissipation channel. The front end of the first air duct is connected to the rear end of the fan cover. This effectively forms the first heat dissipation channel and the fan cavity, and smoothly connects the two, as well as connects the fan cavity and the heat dissipation interlayer via the through hole.

[0024] Furthermore, an exhaust box is provided on the lower surface of the panel of the range housing, where the exhaust window is located. The exhaust box and the lower surface of the panel enclose the exhaust cavity, and the top opening of the exhaust box constitutes the exhaust outlet of the exhaust cavity. The exhaust inlet is provided on the front side wall of the exhaust box, and the exhaust inlet is connected to the rear port of the first air guide cover. This effectively implements the exhaust cavity structure and allows the air discharged from the first heat dissipation channel to be smoothly discharged into the exhaust cavity.

[0025] Furthermore, the opening area of ​​the upper air inlet of the fan chamber is smaller than that of the lower air inlet. This facilitates installation of the fan motor at the top of the fan cover, while also reducing the amount of heat required to dissipate within the stove shell to a smaller amount than the heat dissipation interlayer. By designing the upper and lower air inlets with different opening areas, the overall heat dissipation efficiency of the integrated cooking stove can be improved.

[0026] Compared with the prior art, the present invention has the following advantages: a heat dissipation interlayer is provided between the cooker and the cooking device; a first heat dissipation channel is provided in the cooker housing; an exhaust window is provided on the rear side of the cooker housing panel; a first heat dissipation outlet of the first heat dissipation channel is in fluid communication with the exhaust window; a heat dissipation fan is provided at the first heat dissipation inlet of the first heat dissipation channel; the heat dissipation fan has an upper air inlet and a lower air inlet, wherein the upper air inlet communicates with the inner cavity of the cooker housing, and the lower air inlet communicates with the heat dissipation interlayer. Thus, the first heat dissipation channel can dissipate heat from electrical components installed in the cooker housing and generating heat during operation, thereby preventing the operating environment temperature of the electrical components from being too high, thereby affecting their performance and, in turn, the performance of the entire cooker; and, further, dissipate heat from the heat dissipation interlayer, thereby preventing heat generated during operation of the cooking device (either the cooking device operating alone or simultaneously with the cooker) from accumulating between the cooker and the cooking device, thereby preventing the internal temperature of the cooking device from being too high, thereby ensuring the performance of the cooking device. In addition, the hot air in the heat dissipation interlayer can be discharged from the exhaust window on the rear side of the panel through the first heat dissipation channel, avoiding the problem of hot air directly spraying onto users in the front row.

[0034] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0035] like Figures 1 to 7 As shown, an integrated cooking stove includes a cooking device 1 and a stove 2 mounted on top of the cooking device 1. The cooking device 1 includes a housing 10 and an inner pot 11 disposed within the housing 10. An upper mounting plate 13 is horizontally disposed above the inner pot 11. The stove 2 includes a stove housing 20, which includes a bottom plate 201 with an upper opening and a panel 202 covering the opening of the bottom plate 201. An exhaust window 2021 is provided on the rear side of the panel 202. A first heat dissipation channel 30 having a heat dissipation fan 31 is provided in the bottom plate 201. The first heat dissipation outlet 302 of the first heat dissipation channel 30 is in fluid communication with the exhaust window 2021. Furthermore, in this embodiment, an exhaust port 111 is provided on the back panel of the inner pot 11, which is also in fluid communication with the exhaust window 2021. In this embodiment, an exhaust grille 7 is embedded in the exhaust window 2021.

[0036] Preferably, an exhaust cavity 40 is provided at the rear side of the interior of the cooktop housing 20. The exhaust cavity 40 includes an exhaust outlet 402 in fluid communication with the exhaust window 2021 and an exhaust inlet 401 in fluid communication with the first heat dissipation outlet 302 of the first heat dissipation channel 30. This prevents gas exhausted from the first heat dissipation channel 30 from roaming around within the cooktop housing 20, thereby improving the heat dissipation efficiency of the first heat dissipation channel 30 and preventing any impact on combustion in the burners of the cooktop 2. Specifically, an exhaust box 4 is provided on the lower surface of the panel 202 of the stove housing 20, at the location of the exhaust window 2021. The exhaust box 4 and the lower surface of the panel 202 enclose the exhaust cavity 40, and the top opening of the exhaust box 4 forms the exhaust outlet 402 of the exhaust cavity 40. An exhaust inlet 401 is provided on the front side wall of the exhaust box 4, and the exhaust inlet 401 is connected to the first heat dissipation outlet 302 of the first heat dissipation channel 30, thereby effectively implementing the structure of the exhaust cavity 40 and allowing the exhaust air from the first heat dissipation channel 30 to be smoothly discharged into the exhaust cavity 40. In addition, an air inlet 403 is provided on the bottom wall of the exhaust box 4, which is connected to the exhaust port 111 of the inner pot 11 through the exhaust pipe 112, thereby allowing the gas in the inner pot 11 to be smoothly discharged into the exhaust cavity 40 and discharged to the outside through the exhaust window 2021.

[0037] Furthermore, a heat dissipation interlayer 6 communicating with the outside is formed between the upper surface of the upper mounting plate 13 of the cooking device 1 and the bottom surface of the bottom plate 201 of the stove shell 20. The heat dissipation fan 31 is arranged on the first heat dissipation air inlet 301 of the first heat dissipation channel 30. Figure 3 、 Figure 4 as well as Figure 6 As shown, the heat dissipation fan 31 includes a fan chamber 310 and an impeller 31a mounted therein. The impeller includes an upper impeller 312 and a lower impeller 313. Correspondingly, the fan chamber 310 is provided with an upper air inlet 3141 corresponding to the upper impeller 312 and a lower air inlet 3142 corresponding to the lower impeller 313. The upper air inlet 3141 communicates with the inner cavity of the stove shell 20, while the lower air inlet 3142 communicates with the heat dissipation interlayer 6 via a through-hole 2011 defined in the bottom wall of the chassis 201. In this embodiment, the upper impeller 312 and the lower impeller 313 are coaxially disposed and driven by a motor 315 disposed at the top of the heat dissipation fan 31. Furthermore, preferably, the upper impeller 312 and the lower impeller 313 are integrally formed.

[0038] In the present invention, a heat dissipation interlayer 6 is provided between the stove 2 and the cooking device 1, a first heat dissipation channel 30 is provided in the stove shell 20 of the stove 2, and an exhaust window 2021 is provided on the rear side of the panel 202 of the stove shell 20, the first heat dissipation outlet 302 of the first heat dissipation channel 30 is fluidically connected to the exhaust window 2021, and a heat dissipation fan 31 is provided on the first heat dissipation air inlet 301 of the first heat dissipation channel 30, and the heat dissipation fan 31 has an upper air inlet 3141 and a lower air inlet 3142, wherein the upper air inlet 3141 is communicated with the inner cavity of the stove shell 20, and the lower air inlet 3142 is communicated with the above-mentioned heat dissipation interlayer 6. In this way, the first heat dissipation channel 30 can dissipate heat from the electrical components installed in the stove housing 20 during operation, preventing the operating environment temperature of the electrical components from being too high, which could affect their performance and, in turn, the performance of the entire stove 2. Furthermore, the first heat dissipation channel 30 can dissipate heat from the heat dissipation interlayer 6, preventing heat generated during the operation of the cooking device 1 (either the cooking device 1 operating alone or both the cooking device 1 and the stove 2 operating simultaneously) from accumulating between the stove 2 and the cooking device 1, thus preventing the internal temperature of the cooking device 1 from being too high and ensuring the operating performance of the cooking device 1. Furthermore, the hot air in the heat dissipation interlayer 6 can be discharged through the first heat dissipation channel 30 through the exhaust window 2021 on the rear side of the panel 202, preventing the problem of hot air being directly sprayed onto the user in the front row.

[0039] In this embodiment, the cooker 2 further includes a second electrical component 22 mounted in the cooktop housing 20 and generating heat during operation. The upper air inlet 3141 of the fan chamber 310 is located adjacent to the second electrical component 22. This enhances the heat dissipation effect of the first heat dissipation channel 30 on the second electrical component 22. Specifically, the second electrical component 22 is a display panel mounted on the lower surface of the panel 202.

[0040] Further, if Figure 5As shown, the first heat dissipation channel 30 is arranged along the front-to-back direction, and the setting height of the first heat dissipation channel 30 relative to the inner bottom surface of the chassis 201 increases from the first heat dissipation air inlet 301 to the first heat dissipation air outlet 302, and the fan outlet 3101 of the heat dissipation fan 31 is oriented towards the first heat dissipation air outlet 302, thereby reducing the wind resistance of the airflow in the first heat dissipation channel 30, so that the airflow in the first heat dissipation channel 30 can be discharged more quickly, thereby improving the heat dissipation efficiency. Specifically, it also includes a first air guide cover 3 and a fan cover 311 arranged in the chassis 201 of the above-mentioned stove shell 20 along the front and back. The first air guide cover 3 is in the shape of a sleeve and its inner cavity constitutes the above-mentioned first heat dissipation channel 30. The fan cover 311 is arranged on the inner bottom surface of the chassis 201 where the above-mentioned through hole 2011 is located and forms the above-mentioned fan cavity 310 with the inner bottom surface of the chassis 201. The rear end of the fan cover 311 is opened to form a fan air outlet 3101, and the top wall of the fan cover 311 is opened to form an upper air inlet 3141, and the lower end cover opening of the above-mentioned fan cover 311 constitutes the above-mentioned lower air inlet 3142. The front port of the first air guide cover 3 is the first heat dissipation air inlet 301 of the first heat dissipation channel 30, and the rear port is the first heat dissipation air outlet 302 of the first heat dissipation channel 30, and the front port of the first air guide cover 3 is connected to the rear port of the above-mentioned fan cover 311. This effectively forms the first heat dissipation channel 30 and the fan cavity 310, and smoothly connects the two, as well as connects the fan cavity 310 to the heat dissipation interlayer 6 via the through-hole 2011. In this embodiment, the opening area of ​​the upper air inlet 3141 of the fan cavity 310 is smaller than the opening area of ​​the lower air inlet 3142 (in this embodiment, the opening area of ​​the lower air inlet 3142 is approximately twice that of the upper air inlet 3141). This facilitates installation of the motor 315 of the heat dissipation fan 31 at the top of the fan cover 311. Furthermore, the amount of heat to be dissipated within the stove housing 20 is smaller than that of the heat dissipation interlayer 6. By designing the upper and lower air inlets 3141, 3142, with different opening areas, the overall heat dissipation performance of the integrated cooking stove can be improved.

[0041] Further, if Figure 3As shown, the heat dissipation interlayer 6 is provided with a second heat dissipation channel 50. The second heat dissipation inlet 501 of the second heat dissipation channel 50 communicates with the outside world, while the second heat dissipation outlet 504 communicates with the lower air inlet 3142 of the fan chamber 310 via the through hole 2011. The second heat dissipation channel 50 guides the airflow within the heat dissipation interlayer 6, thereby improving the heat dissipation efficiency of the hot air within the heat dissipation interlayer 6. The front surface of the heat dissipation interlayer 6 is provided with a first vent 101. The second heat dissipation channel 50 is arranged in a front-to-back direction, with the second heat dissipation inlet 501 of the second heat dissipation channel 50 located at its front end and in fluid communication with the first vent 101. Integrated cooking stoves are typically embedded in a cabinet. Therefore, placing the first vent 101 at the front improves the efficiency of cool air entering the second heat dissipation channel 50 through the first vent 101. In this embodiment, a front side plate is connected between the front of the cooker 2 and the front of the cooking device 1 , and the first ventilation openings 101 are composed of long holes spaced apart along the left-right direction on the front side plate.

[0042] Specifically, in this embodiment, a second air scoop 5 is provided on the upper surface of the upper mounting plate. This second air scoop 5 and the upper surface of the upper mounting plate 13 enclose the second heat dissipation channel 50, and the second heat dissipation outlet 504 is provided on the top wall of the second air scoop 5, vertically opposite the through hole 2011. The second air scoop 5 forms a stable second heat dissipation channel 50 structure, and the provision of the second heat dissipation outlet 504 on the top wall of the second air scoop 5 accelerates the efficiency of gas in the second heat dissipation channel 50 entering the heat dissipation fan 31, thereby improving the heat dissipation efficiency of the heat dissipation interlayer 6. Preferably, in this embodiment, the top surface of the second air scoop 5 is in close contact with the bottom surface of the chassis 201, that is, the second heat dissipation outlet 504 of the second heat dissipation channel is vertically overlapped with the through hole 2011.

[0043] Further, if Figure 4As shown, the cooker 2 further includes a third electrical component 23 that generates heat during operation, and the cooking device 1 further includes a water tank 12 disposed on one side of the inner pot 11. An upper mounting space 120 is formed above the water tank 12, communicating with the heat dissipation interlayer 6. The third electrical component 23 is mounted in this upper mounting space 120, and the second heat dissipation channel 50 includes a heat dissipation air inlet 503 communicating with the upper mounting space 120. Specifically, in this embodiment, a mounting plate 15 is horizontally disposed above the water tank 12, and the third electrical component 23 is mounted in this mounting plate 15. The water contained in the water tank 12 has a relatively high specific heat, so the air temperature in the upper installation space 120 above it is relatively low. Placing the third electrical component 23 in the lower-temperature upper installation space 120 can dissipate heat from the third electrical component 23, preventing the ambient temperature from being too high when the third electrical component 23 is operating. Furthermore, the heated air in the upper installation space 120 can be drawn into the second heat dissipation channel 50 through the heat dissipation air inlet 503 and discharged into the heat dissipation fan 31 through the lower air inlet 3142, thereby further enhancing the heat dissipation effect on the third electrical component 23. In this embodiment, the water tank 12 is disposed on the right side of the inner liner 11, and a heat insulation board 14 is provided between the water tank 12 and the inner liner 11, thereby further reducing the air temperature in the upper installation space 120. In addition, the above-mentioned third electrical component 23 is specifically a power board of the stove 2. When the two burners of the stove 2 are working at the same time, the power board generates a lot of heat. When only one burner of the stove 2 is working, the power board generates a little heat. When the stove 2 is not working and only the cooking device 1 is working, the power board itself does not generate heat and is only affected by the residual heat generated by the operation of the cooking device 1.

[0044] Preferably, the second heat dissipation channel 50 is arranged in parallel with the upper portion of the upper installation space 120, and the heat dissipation air inlets 503 are provided on a side of the second heat dissipation channel 50 adjacent to the upper installation space 120. There are at least two heat dissipation air inlets 503 spaced apart, and each heat dissipation air inlet 503 is openable and closable. The opening and closing of each heat dissipation air inlet 503 can be achieved through various existing methods, such as providing a control valve on each heat dissipation air inlet 503. This can improve the heat dissipation efficiency of the warm air in the upper installation space 120, and each heat dissipation air inlet 503 can be opened and closed according to heat dissipation needs. For example, when the temperature of the third electrical component 23 is relatively high, the number of heat dissipation air inlets 503 in the open state exceeds the number of heat dissipation air inlets 503 in the closed state, while when the temperature of the third electrical component 23 is relatively low, the number of heat dissipation air inlets 503 in the closed state exceeds the number of heat dissipation air inlets 503 in the open state. Furthermore, there are four heat dissipation air inlets 503, which are spaced apart along the extending direction of the sidewall of the second air duct 5. Each heat dissipation air inlet 503 is provided with an air inlet connector 5031, and the air inlet port of each air inlet connector 5031 is located in the upper installation space 120. This allows the warm air in the upper installation space 120 to enter the second heat dissipation channel 50 more evenly and quickly and be discharged outside, further improving the heat dissipation effect and heat dissipation efficiency of the third electrical component 23.

[0045] Furthermore, the rear end of the second heat dissipation channel 50 is provided with a third heat dissipation inlet 502 that is openable and closable, communicating with the outside world. This allows cool air from the outside to enter the second heat dissipation channel 50 through the third heat dissipation inlet 502 and rapidly flow through it, driven by the negative pressure at the second heat dissipation outlet 504. This further enhances the heat dissipation effect on the heat dissipation interlayer 6 and the third electrical component 23. When only the cooking device 1 is in operation, the heat dissipation inlets 503 can be closed, while the third heat dissipation inlet 502 is opened. The cool air entering through the third heat dissipation inlet 502 dissipates heat from the third electrical component 23. Furthermore, the provision of the third heat dissipation inlet 502 eliminates the need for a separate heat dissipation fan 31 at the rear end of the second heat dissipation channel 50, simplifying the internal structure of the integrated cooking stove and reducing production costs. Preferably, the third heat dissipation air inlet 502 is provided on the rear end wall of the second air duct 5, and a second vent 102 is provided on the rear side panel of the housing 10 of the cooking device 1. The second vent 102 is in fluid communication with the third heat dissipation air inlet 502, thereby allowing cool air from the outside to more smoothly enter the second heat dissipation channel 50. Furthermore, the cooker 2 further includes a first electrical component 21 disposed within the chassis 201 and requiring operation in a relatively low-temperature environment. The first electrical component 21 is disposed vertically opposite the third heat dissipation air inlet 502, such that cool air entering through the third heat dissipation air inlet 502 can simultaneously dissipate heat from the first electrical component 21.

[0046] In this embodiment, the first electrical component 21 is a weight sensor, and the working environment temperature of the weight sensor needs to be controlled within 60°C (exceeding 60°C will affect the performance of the weight sensor). Preferably, the first electrical component 21 is installed on the inner bottom surface of the chassis 201, and the top wall of the rear end of the second air guide hood 5 protrudes upward to form a heat dissipation boss 51. The top surface of the heat dissipation boss 51 is a heat dissipation plane 511, and the heat dissipation plane 511 is in contact with the outer bottom surface of the chassis 201 where the first electrical component 21 is located, and the third heat dissipation air inlet 502 is opened on the rear side wall of the heat dissipation boss 51. In this way, the cold air entering from the third heat dissipation air inlet 502 converges in the inner cavity of the heat dissipation boss 51, and fully exchanges heat with the heat generated by the first electrical component 21 through the heat dissipation plane 511 and the bottom wall of the chassis 201, further improving the heat dissipation effect of the first electrical component 21.

[0047] In this embodiment, Figure 7 As shown, the cross-section of the second air duct 5 increases from back to front, and the second heat dissipation outlet 504 is located between the second heat dissipation inlet 501 and the third heat dissipation inlet 502. This allows the cold air entering through the second heat dissipation inlet 501 and the third heat dissipation inlet 502 to fully exchange heat with the hot air in the heat dissipation interlayer 6 (including the hot air entering the heat dissipation interlayer 6 from the upper installation space 120), and the mixed air at both ends can be smoothly discharged through the second heat dissipation outlet 504. Preferably, the first side wall 5a of the second air scoop 5 extends in the front-to-back direction, the heat dissipation air inlets 503 are spaced apart along the length of the first side wall 5a, and the second side wall 5b of the second air scoop 5 includes, from back to front, a first wall 52, a second wall 53, and a third wall 54 connected end to end. The first wall 52 is inclined outward from back to front, the second wall 53 extends in the left-right direction, and the third wall 54 extends outward from back to front. The second heat dissipation air outlets 504 are located in front of the second wall 53. This allows the hot air entering the heat dissipation air inlet 503 to fully mix with the cold air entering the second heat dissipation channel 50. Furthermore, the first wall 52 and the third wall 54 can reduce the air flow rate at the front and rear ends of the second heat dissipation channel 50, respectively. The second wall 53 can further reduce the air flow rate flowing to the second heat dissipation air outlets 504, so that the fully mixed and heated mixed air can be concentrated and discharged from the second heat dissipation air outlets 504. Preferably, the opening area of ​​the second heat dissipation air inlet 501 is larger than that of the third heat dissipation air inlet 502. Accordingly, the inclination angle of the third wall 54 relative to the front-to-back direction is larger than that of the first wall 52, so that the cold air entering the second heat dissipation air inlet 501 and the third heat dissipation air inlet 502 can fully and evenly exchange heat with the hot air, further improving the heat dissipation effect.
