The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0063] In response to the future trend of integrated kitchen appliances, the present invention proposes an integrated stove. An integrated stove is a kitchen appliance that integrates multiple functions, such as a gas stove and a steam oven, and has the advantages of taking up little kitchen space and being easy to use.

[0064] In the prior art, integrated stoves use either an integrated oven and steamer or separate ovens. The ovens often use electric heating elements to bake food. Electric ovens have low heat conversion efficiency, resulting in high baking costs and difficulty achieving high-temperature baking, which affects cooking results.

[0065] To solve the above problems, please refer to Figure 1 and Figure 2The integrated stove 1000 proposed in the embodiment of the present application includes a stove 100 and a cooking device 200. The stove 100 and the cooking device 200 can be embedded in the kitchen stove as a whole or separately, or connected to the cabinet 2000. The cooking device 200 can be optionally arranged under the stove 100 to reasonably utilize the kitchen space.

[0066] The stove 100 includes a stove housing 10 and a burner head 20. The stove housing 10 defines a mounting cavity 101. The burner head 20 is disposed within the mounting cavity 101 and connected to a combustion gas source via a gas line 300. Optionally, the upper surface of the stove housing 10 forms a portion of the kitchen countertop, with the burner head 20's burner hole exposed outside the mounting cavity 101. Optionally, the stove 100 may also be equipped with a pot holder 30. The pot holder 30 is connected to the stove housing 10 and surrounds the burner head 20's burner hole for holding pots and facilitating heating by the stove 100. Of course, the present embodiment does not limit the specific structure of the pot holder 30 or the number of burners 20 that the stove 100 may have. For example, the stove 100 may be equipped with two or three burners 20 spaced side by side to improve cooking efficiency.

[0067] like Figures 2 to 4 As shown, the cooking device 200 includes a housing 40, a baking assembly 50, and a steam assembly 60. The housing 40 is disposed below the cooker 100 and is used to provide a mounting base for the baking assembly 50 and the steam assembly 60, and forms at least a portion of the exterior surface of the cooking device 200. The housing 40 has a cooking cavity 411 and a heating air duct 46a that are interconnected. The housing 40 is provided with an access opening 413 that communicates with the cooking cavity 411. Food materials can be placed into the cooking cavity 411 or removed from the cooking cavity 411 through the access opening 413. Optionally, a tray 417 for supporting food is further provided in the cooking cavity 411. The tray 417 may have holes or be in the shape of a fence to facilitate airflow.

[0068] The baking assembly 50 includes a burner 53 and a circulating fan 51, both of which are located within the heating duct 46a. The burner 53 is used to heat the airflow within the heating duct 46a and is also connected to an external combustion gas source via the gas pipeline 300. Alternatively, the burner 53 and the burner head 20 can be connected to the same external combustion gas source, with the gas flow divided by a pipeline. Alternatively, the burner 53 and the burner head 20 can be connected to different combustion gas sources. The circulating fan 51 can be a crossflow fan or a centrifugal fan, and is used to circulate air between the cooking cavity 411 and the heating duct 46a. For example, the circulating fan 51 can draw air from the cooking cavity 411 into the heating duct 46a, where it is heated by the burner 53 and then flows into the cooking cavity 411 to heat the food. Alternatively, the circulating fan 51 can draw air from the heating duct 46a, heated by the burner 53, and blow it into the cooking cavity 411. Thus, when the circulating fan 51 is running, air can continuously circulate between the cooking cavity 411 and the heating air duct 46a, so that the high-temperature air heats and bakes the food in the cooking cavity 411. It can be understood that temperature adjustment can be achieved by controlling the gas control valve connected to the gas pipeline 300 of the burner 53.

[0069] The steam assembly 60 includes a steam generator 61 connected to the housing 40. The steam generator 61 has a water inlet and a steam outlet. The water inlet is connected to a water source, and steam generated by heating is discharged from the steam outlet. The steam outlet is connected to the cooking chamber 411 to process food with steam.

[0070] As can be seen, in the embodiment of the present application, both the steam assembly 60 and the baking assembly 50 are capable of processing food within the cooking cavity 411. This food processing inevitably generates fumes that need to be promptly exhausted, or when the steam assembly 60 is operating, steam needs to be promptly exhausted. The housing 40 of the present embodiment also has an air outlet 412 communicating with the cooking cavity 411. In some configurations, a range hood is located above the kitchen stove. To facilitate the range hood's extraction of fumes and steam from the air outlet 412, the cooker 100 is provided with an exhaust port 11a. The air outlet 412 is fluidly connected to the exhaust port 11a, allowing fumes and steam within the cooking cavity 411 to flow through the air outlet 412 and be exhausted through the exhaust port 11a. This shortens the distance between the fumes and steam outlet and the range hood, improves the efficiency and effectiveness of steam and fumes exhaust, enhances the operating quality of the integrated cooker 1000, and reduces or prevents fumes from accumulating. Optionally, the air outlet 412 and the exhaust port 11a can be connected by a pipe.

[0071] In summary, the embodiment of the present application provides a heating air duct 46a in communication with the cooking cavity 411, and uses a circulating fan 51 to achieve air circulation between the heating air duct 46a and the cooking cavity 411. The airflow is heated by a burner 53, thereby achieving a baking process for the food in the cooking cavity 411. Compared with the technical solutions of the related art that use electric heating for baking, the present application uses a burner 53 for heating, which can easily achieve higher baking temperatures and realize more diverse baking processes for food at a lower cost. Moreover, the circulating fan 51 creates an air circulation between the heating air duct 46a and the cooking cavity 411 to bake the food, which not only improves baking efficiency but also makes the temperature in the cooking cavity 411 more uniform, thereby improving the food processing effect.

[0072] In addition, the steam component 60 and the baking component 50 of the embodiment of the present application share the cooking cavity 411. Food can be baked and steamed in the cooking cavity 411, and the space utilization rate is high.

[0073] Next, the specific structure of the integrated stove 1000 will be explained in conjunction with the accompanying drawings. Figure 3 and Figure 4 The front-to-back direction, left-to-right direction, and up-down direction are shown.

[0074] like Figure 3 and Figure 5 As shown, in some embodiments, the box body 40 includes a box body 41 and a box door 401 connected to the front side of the box body 41, a first side cover shell 42 connected to the rear side of the box body 41, a second side cover shell 43 connected to the right side of the box body 41, a third side cover shell 44 connected to the left side of the box body 41, and a top cover shell 45 connected to the top of the box body 41.

[0075] The box body 41 defines a cooking cavity 411 with a front opening, and the front opening is the aforementioned access opening 413. The box door 401 is movably connected to the box body 41. For example, the box door 401 is connected to the box body 41 by a hinge and moves in a flipping manner to open or close the access opening 413. Optionally, the hinge can be set on the lower side of the access opening 413; or, the box door 401 can also be connected to the box body 41 by a sliding connection or other methods. The embodiments of the present application will not be described in detail here. A water receiving tray 418 is also provided in the box body 41. The water receiving tray 418 is located between the tray 417 and the bottom wall of the cooking cavity 411, and the top wall of the water receiving tray 418 is spaced apart from the bottom wall of the cooking cavity 411 to reduce the heat directly conducted to the bottom of the box body 41.

[0076] The first side cover 42, the second side cover 43, the third side cover 44, and the top cover 45 can be connected to the box body 41 by one or more of the following connection methods: screw connection, snap connection, etc., which is not limited in this embodiment of the present application. A first installation space 421 is defined between the first side cover 42 and the box body 41, a second installation space 431 is defined between the second side cover 43 and the box body 41, a third installation space 441 is defined between the third side cover 44 and the box body 41, and a top installation space 451 is defined between the top cover 45 and the box body 41. In this way, a space is set between the cooking cavity 411 and the outside world to prevent the surface temperature of the box body 40 from being too high, ensuring safety in use and improving the user experience.

[0077] Please combine Figure 3 and Figure 6 In one embodiment, the cabinet 40 further includes an air duct housing 46, which is connected to the cabinet body 41 and cooperates to form a heating air duct 46a. Specifically, an air outlet 414 and an air inlet 415 are provided on the sidewalls of the cabinet body 41, which communicate with the cooking cavity 411. The air duct housing 46 is disposed within the first installation space 421. The air duct housing 46 includes an inner shell 461 and an outer shell 462. The inner shell 461 is connected to the cabinet body 41 and defines an inner air duct 46a1 with the cabinet body 41, which communicates with the air outlet 414. The outer shell 462 covers the inner shell 461, and an outer air duct 46a2 is defined between the outer shell 462 and the inner shell 461. The outer air duct 46a2 communicates with the air inlet 415. The inner shell 461 also defines a connecting port 461a connecting the inner air duct 46a1 with the outer air duct 46a2. When the circulation fan 51 is in operation, the airflow within the cooking cavity 411 flows sequentially through the air outlet 414, the inner air duct 46a1, the connecting port 461a, the outer air duct 46a2, and the air inlet 415, returning to the cooking cavity 411 for circulation. Thus, in this embodiment of the present application, the heating duct 46a is disposed on one side of the cooking cavity 411, and the circulation fan 51 and burner 53 are both disposed within the heating duct 46a, i.e., on one side of the cooking cavity 411. This makes the structure more compact and avoids occupying more space in the cabinet 40.

[0078] In such Figure 3 In the illustrated embodiment, the air duct housing 46 is disposed on the rear side of the box body 41, such that the heating air duct 46a is disposed on the side away from the access opening 413. Of course, in other embodiments, the air duct housing 46 may also be disposed on the left or right side of the box body 41, and this embodiment of the present application is not limited thereto.

[0079] In one embodiment, the burner 53 is disposed in the inner air duct 46a1, and at least a portion of the circulation fan 51 is disposed in the outer air duct 46a2. The circulation fan 51 includes a motor 511 and a first impeller 512. The motor 511 has a rotating shaft 5111, and the first impeller 512 is connected to the rotating shaft 5111. At least a portion of the circulation fan 51 is disposed in the outer air duct 46a2. The rotating shaft 5111 can extend into the outer air duct 46a2 so that the first impeller 512 is located in the outer air duct 46a2, or the motor 511 and the first impeller 512 are both disposed in the outer air duct 46a2. In this embodiment, the motor 511 is fixed to the housing 462, the rotating shaft 5111 extends into the outer air duct 46a2, and the first impeller 512 is located in the outer air duct 46a2. This minimizes the occupation of the circulation fan 51 in the outer air duct 46a2, improves space utilization, and prevents high-temperature airflow from affecting the operation of the motor 511. When the motor 511 is running, the rotating shaft 5111 rotates, driving the first impeller 512. The first impeller 512 disturbs the air in the outer air duct 46a2, causing it to flow into the cooking chamber 411 through the air inlet 415. Under the influence of negative pressure, the air in the cooking chamber 411 flows through the air outlet 414 into the inner air duct 46a1. The air in the inner air duct 46a1 then flows into the outer air duct 46a2. As the air flows through the inner air duct 46a1, the heat emitted by the burner 53 heats the air. In this embodiment, the burner 53 is located upstream of the fan along the air flow path within the heating air duct 46a. This allows the burner 53 to fully heat the airflow, which is then disturbed by the circulation fan 51, improving the temperature uniformity of the airflow. Furthermore, the burner 53 is closer to the cooking chamber 411 than the circulation fan 51, allowing some of the heat generated by combustion to be directly radiated into the cooking chamber 411, which helps increase the heating rate within the cooking chamber 411 and maintain the temperature of the cooking chamber 411.

[0080] It can be understood that, under the premise that the burner 53 can heat the air in the heating air duct 46a, in other embodiments, the burner 53 can also be arranged in the outer air duct 46a2, and at least part of the circulation fan 51 is located in the inner air duct 46a1, so that the circulation fan 51 is arranged on the upstream side of the burner 53. The embodiments of the present application are not limited to this.

[0081] The following explanation will continue with an example in which the burner 53 is arranged in the inner air duct 46a1 and at least part of the circulation fan 51 is arranged in the outer air duct 46a2.

[0082] Combine Figures 6 to 8In one embodiment, the inner air duct 46a1 includes a connected air cavity 4611a and a combustion cavity 4612a, and the inner shell 461 includes a connected air duct portion 4611 and a combustion portion 4612. The air duct portion 4611 is connected to the box body 41 and defines the air cavity 4611a together with the box body 41, and the combustion portion 4612 is connected to the inner shell 461 and defines the combustion cavity 4612a together with the box body 41. Figure 6 As shown, the combustion chamber 4612a is located below the air chamber 4611a, and the burner 53 is located in the combustion chamber 4612a and is fixedly connected to the box body 41 or the combustion part 4612. Specifically, the burner 53 is arranged below the air outlet 414, and the fire hole of the burner 53 is arranged upward. In this way, the burner 53 does not block the air outlet 414, allowing the airflow to pass through the air outlet 414 smoothly. The rising heat generated by the combustion of the burner 53 can better heat the airflow.

[0083] Furthermore, the combustion portion 4612 is extended in the horizontal direction. Figure 7 As shown, the combustion portion 4612 defines a combustion chamber 4612a extending horizontally in the left-right direction. Correspondingly, the multiple fire holes of the burner 53 are also arranged horizontally in the left-right direction, so that the burner 53 can evenly heat the airflow passing through. It is understood that in other structural forms, such as a structural form in which the air duct housing 46 is arranged on the right side of the box body 41, the burner 53 can also be arranged horizontally in the front-to-back direction; even more, the combustion portion 4612 and the burner 53 can also be arranged to extend in the up-down direction or diagonally, and this embodiment of the application is not limited to this.

[0084] Please continue to see Figure 6 and Figure 8 The combustion portion 4612 is provided with an air supply port 4612b communicating with the combustion chamber 4612a. The air supply port 4612b communicates with the first installation space 421. The first installation space 421 communicates with the outside world through an opening provided in the first side cover 42, thereby facilitating air supply and ensuring continuous combustion of the burner 53. Exemplarily, the air supply port 4612b includes a plurality of air supply mesh holes, which can be strip-shaped or circular, to ensure uniform air supply and a uniform flame from the burner 53.

[0085] Optionally, the combustion section 4612 and the air duct section 4611 are formed as two separately formed parts, which can be connected by welding, bolting, clamping, etc. after forming, facilitating production and assembly. Alternatively, the combustion section 4612 and the air duct section 4611 can be an integrated structure to reduce the number of parts and improve structural integrity.

[0086] The connecting port 461a is arranged in the air duct portion 4611 and is roughly circular. In one embodiment, the air outlet 414 is also roughly circular, and the central axis of the connecting port 461a is parallel to or coincides with the central axis of the air outlet 414 to reduce obstructions in the air flow path, reduce the pressure loss of the air flow, improve the smoothness of the air flow, and ensure air circulation.

[0087] Furthermore, the axis of the rotating shaft 5111 is parallel to or coincides with the central axis of the connecting opening 461a. In other words, the central axis of the first impeller 512 is parallel to or coincides with the central axis of the connecting opening 461a, thereby improving air circulation efficiency. When the axis of the rotating shaft 5111 coincides with the central axis of the connecting opening 461a, the first impeller 512 can directly disturb the airflow flowing from the connecting opening 461a into the external air duct 46a2, directing it toward the air inlet 415. This ensures that the airflow blown by the first impeller 512 is uniform in all directions, reducing airflow turbulence.

[0088] For example, in this application Figure 6 In the illustrated embodiment, the central axis of the communication port 461a coincides with the central axis of the air outlet 414, and the axial direction of the rotating shaft 5111 coincides with the central axis of the communication port 461a, thereby achieving smooth air circulation and high working efficiency.

[0089] Projected along the front-to-back direction, the projection of the air duct portion 4611 is within the projection of the outer shell 462. Between the projection of the outer shell 462 and the projection of the air duct portion 4611, the cabinet body 41 is provided with multiple air inlets 415. These inlets 415 are located on at least one side of the circumference of the air outlet 414 and are all connected to the external air duct 46a2. In one specific embodiment, the cabinet body 41 is provided with six air inlets 415, symmetrically arranged on the left and right sides of the air outlet 414. As a result, air flows from the cooking cavity 411 through the air outlet 414 into the heating duct 46a, and then flows into the cooking cavity 411 through the six air inlets 415. This creates an air circulation between the cooking cavity 411 and the heating duct 46a, while also ensuring uniform airflow distribution within the cooking cavity 411 and improving cooking efficiency. Furthermore, air outlets 414 are located behind tray 417 within cooking cavity 411. When cooking food, airflow entering cooking cavity 411 from six air inlets 415 surrounds the food on tray 417, with nearly all of the airflow passing through the food and toward air outlets 414, ensuring that the food is adequately heated. Of course, the present embodiment is not limited to a specific number of air inlets 415; oven body 41 may also be provided with five, seven, or other numbers of air inlets 415.

[0090] Optionally, the air outlet 414 and the air inlet 415 are circular or square in shape, wherein the air outlet 414 includes multiple outlet mesh holes, and the air inlet 415 includes multiple inlet mesh holes. The smaller mesh holes not only prevent foreign matter from entering the heating air duct 46a from the cooking cavity 411, but also organize the airflow passing through, reducing or avoiding airflow turbulence and improving air circulation efficiency. Of course, the air outlet mesh holes and the air inlet mesh holes may also be circular or square in shape, and this embodiment of the application is not limited thereto.

[0091] like Figure 6 As shown, in one embodiment, the outer shell 462 is provided with a mounting groove 4621, the bottom wall of which is arched in a direction away from the inner shell 461. The first impeller 512 is located in the mounting groove 4621, thereby reducing the space occupied by the first impeller 512 relative to the external air duct 46a2 and improving the air circulation efficiency. It is worth mentioning that the outer shell 462 can include two parts: the outer shell 462 body and a mounting plate. The mounting plate is connected to the outer shell 462 body and together with the outer shell 462 body, defines the mounting groove 4621. The motor 511 is connected to the mounting plate, and the rotating shaft 5111 passes through the mounting plate and extends into the mounting groove 4621. This facilitates assembly and improves installation efficiency.

[0092] Understandably, the motor 511 generates heat during operation, and heat accumulation may affect the operation of the motor 511. To this end, in one embodiment, the circulating fan 51 further includes a second impeller 513. The second impeller 513 is located outside the air duct housing 46 and is connected to the rotating shaft 5111. It is spaced apart from the first impeller 512. When the motor 511 is running, the rotation of the rotating shaft 5111 drives the first impeller 512 and the second impeller 513 to rotate synchronously. The second impeller 513 can guide airflow to dissipate heat from the motor 511, ensuring the normal operation of the motor 511 and improving the structural reliability.

[0093] Specifically, the first side cover 42 is provided with a first air outlet 422, and the housing 40 or the first side cover 42 is provided with a second air outlet 452. The first air outlet 422 and the second air outlet 452 are both connected to the first installation space 421. When the second impeller 513 rotates, external air can enter the first installation space 421 through the first air outlet 422, flow through the motor 511, and then flow out through the second air outlet 452, thereby removing heat from the motor 511. Furthermore, to improve the heat dissipation effect, the housing 40 also includes a fan housing 47 connected to the first side cover 42. The fan housing 47 defines an air guide channel 471. The air guide channel 471 is connected to both the first air outlet 422 and the second air outlet 452, so that airflow enters the air guide channel 471 from the first air outlet 422 and flows out from the second air outlet 452. This can concentrate the airflow entering the first installation space 421, which is conducive to the airflow providing concentrated heat to the motor 511.

[0094] Optionally, the first air vent 422 is positioned opposite the second impeller 513 to facilitate the extraction of external air by the second impeller 513. The second air vent 452 is located at the top of the housing 40 along the height direction of the integrated stove 1000 to facilitate the discharge of hot air after heat exchange with the motor 511. Furthermore, both the first air vent 422 and the second air vent 452 are formed with multiple through holes to prevent excessive openings from allowing foreign matter to enter the first installation space 421, while also streamlining the airflow and reducing air turbulence.

[0095] Obviously, the second impeller 513 and the fan cover 47 for dissipating heat from the motor 511 are both arranged outside the air duct shell 46. This is undoubtedly another benefit of arranging the circulating fan 51 in the outer air duct 46a2, which facilitates the heat dissipation design of the circulating fan 51.

[0096] Please combine Figure 4 In some embodiments, the steam component 60 is arranged in the second installation space 431, that is, the steam component 60 is arranged on the right side of the box body 41, and the heating air duct 46a is arranged on the rear side of the box body 41. The steam component 60 and the heating air duct 46a are arranged on opposite sides to reasonably utilize the space of the box body 40.

[0097] Optionally, the steam assembly 60 further includes a water tank 62 and a water pump 63. Both are disposed within the second mounting space 431 and are connected to the housing body 41. The water pump 63 has a water inlet connected to the interior of the water tank 62 and a water outlet connected to the interior of the steam generator 61, thereby drawing water from the water tank 62 and pumping it into the steam generator 61. A steam outlet connects to the cooking cavity 411 through a sidewall thereof. When the steam generator 61 is in operation, it heats water to form steam, which is then discharged from the steam outlet into the cooking cavity 411 to process food. Thus, by controlling the start / stop and power level of the water pump 63, it is possible to control whether water is supplied to the steam generator 61 and the amount of water supplied, thereby controlling the start / stop of steam generation and the amount of steam supplied. It can be understood that setting the water tank 62 in the second installation space 431 not only makes it convenient for the water pump 63 to deliver water in a timely manner, but also because water has a large specific heat capacity, the water in the water tank 62 can also absorb the heat radiated from the cooking cavity 411 to the second installation space 431, thereby playing a heat dissipation role.

[0098] Please combine Figure 4In one embodiment, the integrated stove 1000 further includes an electronic control component and a partition 48 connecting the box body 41, and the partition 48 divides the second installation space 431 into a first subspace 4311 and a second subspace 4312. The water tank 62 and the steam generator 61 are located in the first subspace 4311, and the electronic control component and the water pump 63 are located in the second subspace 4312, and the water pump 63 is connected to the partition 48. In this way, the electronic control component and the water pump 63 are arranged in the same space to facilitate wiring operations. Optionally, the first subspace 4311 and the second subspace 4312 are arranged up and down, the first subspace 4311 is located below the second subspace 4312, and the electronic control component is arranged in the second subspace 4312 for easy wiring, and as Figure 4 As shown, the second subspace 4312 is disposed entirely near the top of the housing 40 and relatively far from the cooking cavity 411, thereby reducing the impact of heat on the electronic control components. Of course, the first subspace 4311 and the second subspace 4312 may also be disposed side by side front to back, and this embodiment is not limited thereto.

[0099] To further ensure stable operation of the electronic control components, in one embodiment, the integrated cooktop 1000 further includes a heat dissipation fan 70 located in the second subspace 4312. The second side cover 43 is provided with an air vent 432 that connects to the second subspace 4312, and the heat dissipation fan 70 is positioned near the air vent 432. The heat dissipation fan 70 may be a centrifugal fan, with the air outlet 414 of the fan volute facing the electronic control components. Optionally, a portion of the first side cover 42 or the second side cover 43 forms the rear sidewall of the second subspace 4312. The first side cover 42 or the second side cover 43 is further provided with a through hole that connects to the second subspace 4312. The second subspace 4312 extends in the front-to-back direction, and the air vent 432 is located on the front side of the second side cover 43. Under the action of the heat dissipation fan 70, air flows from the front to the rear of the second subspace 4312 through the air vent 432 and is discharged through the hole, thereby dissipating heat from the electronic control components and the water pump 63. In this way, the airflow entering the second subspace 4312 from the air vent 432 is discharged after exchanging heat with the electronic control components through the heat dissipation fan 70, thereby dissipating the heat of the electronic control components in time, avoiding heat accumulation affecting the operation of the electronic control components, and improving the reliability of the integrated stove 1000.

[0100] Specifically, the air holes 432 include a plurality of air meshes, and the shapes of the air meshes can be circular, square, strip, etc. The smaller air meshes can prevent foreign matter from entering the second subspace 4312, and can organize the airflow and reduce airflow turbulence.

[0101] Please combine Figure 9The housing 40 further forms heat dissipation ducts 40a on the left and top sides of the main body 41. In one embodiment, the integrated stove 1000 further includes a guide fan 80. The heat dissipation ducts 40a include a first duct 40a1 located on the left side of the main body 41 and a second duct 40a2 located at the top of the main body 41 along the height direction of the integrated stove 1000. The left end of the second duct 40a2 is connected to the top of the first duct 40a1. The guide fan 80 is located at the connection point between the first duct 40a1 and the second duct 40a2. At the same time, the box body 40 is provided with a heat dissipation air inlet 442 connected to the first air duct 40a1 and a heat dissipation air outlet 416 connected to the second air duct 40a2. The guide fan 80 can be selected as a cross-flow fan. When the guide fan 80 is running, the external air flow can flow through the heat dissipation air inlet 442 in sequence - the first air duct 40a1 - the guide fan 80 - the second air duct 40a2, and then be discharged through the heat dissipation air outlet 416. During the flow of the air flow, the heat of the third installation space 441 and the top installation space 451 is taken away, thereby realizing the heat dissipation of the cooking device 200 and avoiding heat accumulation affecting the use of the integrated stove 1000. Furthermore, positioning the guide fan 80 at the junction of the first air duct 40a1 and the second air duct 40a2, that is, at the angle between the two sides of the cabinet 40, simultaneously dissipates heat from the sides and top of the cabinet 40 while preventing the guide fan 80 from excessively occupying the central or lateral space of the cooking device 200. This improves space utilization within the cabinet 40 and facilitates structural layout. Furthermore, positioning the guide fan 80 at the junction of the first air duct 40a1 and the second air duct 40a2 effectively guides the airflow within both the first and second air ducts 40a1, 40a2, ensuring smoother airflow. Furthermore, positioning the guide fan 80 at the junction of the two sides of the cabinet 40 also increases the strength of the cabinet 40 frame, improving structural reliability.

[0102] Of course, this embodiment illustrates the first air duct 40a1 on the left side of the cabinet 40. However, the first air duct 40a1 is not limited to being located on the left side of the cabinet 40, nor is it limited to being located on only one side of the cabinet 40. Alternatively, the heat dissipation inlet 442 may be connected to the second air duct 40a2, and the heat dissipation outlet 416 may be connected to the first air duct 40a1. For example, in some configurations, the first air duct 40a1 may be located on the left side, the rear side, and the back side of the cabinet body 41. In other words, by disposing the first air duct 40a1 on at least one side of the cabinet body 41 and positioning the air guide fan 80 within the heat dissipation duct 40a, more comprehensive heat dissipation of the cooking device 200 is achieved. This application will not elaborate further here.

[0103] Please refer to the specific Figure 9In one embodiment, the third side cover 44 and the box body 41 jointly define a first air duct 40a1. The second air duct 40a2 is disposed within the top cover 45. The heat dissipation air inlet 442 is disposed on the third side cover 44, and the heat dissipation air outlet 416 is disposed on the box body 41 or the top cover 45. The heat dissipation air outlet 416 is disposed on the same side as the access opening 413. In this embodiment, the heat dissipation air outlet 416 is disposed on the front side of the box body 41 to dissipate hot air toward the front, thereby preventing heat accumulation on the left and right sides and rear side of the box body 40.

[0104] The guide fan 80 is arranged at the upper left of the box body 41, and blows air to the right along the second air duct 40a2. The heat dissipation outlet 416 is arranged at the front side, and the air flow has a large turn. In order to make the air flow turn more smoothly, in one embodiment, the box body 40 further includes an air guide shell 49, which is connected to the box body 41 and defines the second air duct 40a2 with the box body 41. Furthermore, the air guide shell 49 extends in an arc shape so that one end of the second air duct 40a2 is connected to the first air duct 40a1 and the other end is connected to the heat dissipation outlet 416. Figure 10 As shown, the arc-shaped extended air guide shell 49 can guide the airflow blown out by the guide fan 80 to the heat dissipation outlet 416, making the airflow in the second air duct 40a2 smoother, reducing the loss along the way, improving the heat dissipation efficiency, and reducing noise, thereby improving the operating quality of the integrated stove 1000.

[0105] Optionally, the heat dissipation outlet 416 includes a plurality of sub-outlets spaced apart in the horizontal direction. Figure 10 In the illustrated embodiment, multiple sub-air vents are spaced apart in the left-right direction. The sub-air vents can be circular, square, or strip-shaped. Smaller sub-air vents can prevent foreign matter from entering the second air duct 40a2 and can evenly distribute the airflow, reducing airflow turbulence. Of course, in other embodiments, a strip-shaped heat dissipation outlet 416 can also be provided on the box body 41, but this embodiment of the present application is not limited thereto. Similarly, the heat dissipation inlet 442 can also include multiple air vents, which will not be described in detail here.

[0106] In one embodiment, the door 401 is provided with an inner door air duct 46a1, which is configured to connect to the heat dissipation outlet 416 when the door 401 closes the access opening 413. Optionally, the door 401 is provided with a vent corresponding to the heat dissipation outlet 416. When the door 401 closes the access opening 413, the inner wall of the door 401 fits against the box body 41, and the heat dissipation outlet 416 and the vent are correspondingly connected, so that air can flow from the heat dissipation outlet 416 through the vent into the inner door air duct 46a1. The inner door air duct 46a1 can be arranged along the four sides of the door 401, and the embodiment of the present application does not expand on this limitation. It can be understood that by connecting the inner door air duct 46a1 to the second air duct 40a2, it can also achieve the effect of dissipating heat for the door 401, preventing the door 401 from overheating and scalding the user, thereby ensuring safe use. The air outlet of the door 401 connected to the door internal air duct 46a1 can be set at the bottom of the door 401, so that the airflow in the door internal air duct 46a1 can be discharged from the bottom of the door 401, avoiding the airflow directly rushing towards the user, thereby improving the user experience.

[0107] Of course, in some other structural forms, the box door 401 may not have an inner door channel, and the airflow flowing out of the heat dissipation outlet 416 is directly discharged to the surrounding areas of the box door 401 through the gap between the box door 401 and the box body 41.

[0108] It is worth mentioning that, in one embodiment, the gas pipeline 300 is also introduced from the third installation space 441 and includes a gas main pipe and a gas branch pipe. One end of the gas main pipe is exposed outside the third installation space 441 and is used to connect to the external gas pipe, and the other end extends upward to connect to the burner head 20. The gas branch pipe is connected to the gas main pipe and passes through the first installation space 421 to connect to the burner 53.

[0109] The above content introduces the specific structural forms of the heating air duct 46a, the baking component 50, the steam component 60 and the heat dissipation device. The exhaust structure of the cooking cavity 411 is explained in detail below with reference to the accompanying drawings.

[0110] Please refer to Figure 3 and Figure 11 In some embodiments, the integrated cooker 1000 further includes an exhaust assembly 90 connected to the housing 40. The exhaust assembly 90 defines an exhaust passage 91, which connects the air outlet 412 and the exhaust port 11a. This allows oil smoke and steam within the cooking cavity 411 to flow along the exhaust passage 91 toward the exhaust port 11a. The exhaust assembly 90 is a sheet metal component. Made of metal, the exhaust assembly 90 offers high strength, maintaining the shape of the exhaust passage 91 and ensuring smooth exhaust. Furthermore, the exhaust assembly 90 can withstand higher temperatures, improving its structural reliability and facilitating the cooking device 200 to process food at higher temperatures, thereby increasing the versatility of cooking processes.

[0111] In one embodiment, the stove housing 10 includes a chassis 13 and a panel 11 connected to each other. The chassis 13 and the panel 11 together define an installation cavity 101. An exhaust port 11a is provided on the panel 11, and a clearance port is provided on the chassis 13. Both the exhaust port 11a and the clearance port are connected to the installation cavity 101. The exhaust assembly 90 is provided through the clearance port to pass through the installation cavity 101. The end of the exhaust assembly 90 away from the housing 40 is located outside the exhaust port 11a, thereby connecting the exhaust passage 91 to the exhaust port 11a. It is understandable that, compared to some solutions that use a hose to connect the air outlet 412 and the air outlet 11a, the exhaust assembly 90 in the embodiment of the present application achieves a hard connection between the air outlet 412 and the air outlet 11a, eliminating the need for complex pipe connections, making assembly simpler and more direct, and improving assembly efficiency.

[0112] Of course, in some other structural forms, the range housing 10 may also be positioned away from the exhaust assembly 90 so that the exhaust assembly 90 does not pass through the installation cavity 101 but is directly connected to the exhaust port 11 a from outside the range housing 10 .

[0113] The following description will still be made based on the embodiment in which the exhaust assembly 90 passes through the installation cavity 101 .

[0114] Combine Figures 11 to 13 In one embodiment, the exhaust passage 91 includes a first air passage 921 and a second air passage 931, and the exhaust assembly 90 includes a first exhaust member 92 and a second exhaust member 93. The first exhaust member 92 is located in the top mounting space 451 and connects the main body 41 and the top housing 45. The first exhaust member 92 defines a first air passage 921. The second exhaust member 93 connects to the top housing 45 and defines a second air passage 931. The top housing 45 is provided with an exhaust connection port 453. The first air passage 921 connects the air outlet 412 and the exhaust connection port 453, while the second air passage 931 connects the exhaust connection port 453 and the exhaust port 11a. This allows smoke and steam within the cooking chamber 411 to be discharged sequentially through the air outlet 412, the first air passage 921, the exhaust connection port 453, the second air passage 931, and the exhaust port 11a. It can be understood that the first exhaust member 92 and the second exhaust member 93 are both sheet metal members, and are connected to the top cover shell 45 and the box body 41 by bolt connection, snap connection, etc.

[0115] In some configurations, the second air duct 931 includes a transition section 9311 and a channel section 9312. The transition section 9311 connects to the exhaust port 453, while the channel section 9312 connects to the transition section 9311 and the exhaust port 11a. Specifically, the channel section 9312 and the first air duct 921 both extend along the height of the integrated stove 1000, and the channel section 9312 and the first air duct 921 are offset in a direction perpendicular to the height. In some embodiments of the integrated stove 1000, due to various design considerations, the exhaust port 11a and the air outlet 412 are not directly opposite each other, but are offset. Therefore, in the embodiments of the present application, the channel section 9312 and the first air duct 921 are also offset accordingly. For example, in one embodiment, the air outlet 412 is closer to the front side than the exhaust port 11 a , and accordingly, the first air channel 921 is closer to the front side than the channel section 9312 , so as to be able to respectively connect the air outlet 412 and the exhaust port 11 a .

[0116] Furthermore, the cross-sectional area of ​​the first air channel 921 is larger than the cross-sectional area of ​​the channel section 9312. The cross-sectional shapes of the first air channel 921 and the channel section 9312 are not limited. Making the cross-sectional area of ​​the channel section 9312 smaller not only facilitates matching with the exhaust port 11a, but also accelerates the flow rate of the smoke and steam, facilitating exhaust.

[0117] The transition section 9311 is used to transitionally connect the first air channel 921 and the channel section 9312, so that the airflow from the first air channel 921 to the channel section 9312 flows more smoothly. Optionally, at least one side wall of the transition section 9311 is tilted relative to the height direction of the integrated stove 1000 to transitionally connect the first air channel 921 and the channel section 9312. Figure 11 In one embodiment, the front sidewall of the transition section 9311 extends upward and obliquely from front to back, and the front sidewall of the transition section 9311 faces the air outlet 412. The flue gas and steam entering the first air passage 921 from the air outlet 412 are guided by the transition section 9311 to flow smoothly into the passage section 9312, thereby achieving smoother exhaust and higher efficiency. Of course, the front sidewall of the transition section 9311 may also extend in an arc shape to guide airflow, but this embodiment of the present application is not limited thereto.

[0118] In one embodiment, the exhaust port 11a is provided at the rear side of the stove housing 10, and the air outlet 412 is provided at the rear side of the cooking device 200. Generally, a range hood is provided at the rear side of a stove, so that the smoke and steam exhausted from the exhaust port 11a can be extracted by the range hood, thereby maintaining a clean cooking environment.

[0119] Optionally, the stove shell 10 further includes a baffle 15, which is movably connected to the panel 11 and blocks the exhaust port 11a. The baffle 15 and the panel 11 may be connected in a limited manner so that they can be taken and placed at any time, or the baffle 15 and the panel 11 may be rotatably connected so that the baffle 15 can be opened to observe the exhaust port 11a, which is convenient for cleaning and maintenance operations. An exhaust grille is provided on the baffle 15, and the exhaust grille forms a plurality of exhaust sub-holes. The shape of the exhaust sub-holes can be circular, square, strip-shaped, etc. The smaller exhaust sub-holes can prevent foreign matter from entering the exhaust port 11a, and can comb the airflow, so that the airflow flows out evenly and reduces airflow turbulence. Similarly, if Figure 13 As shown, the air outlet 412 includes multiple air outlet mesh holes, and the shape of the air outlet mesh holes can also be circular, square, strip-shaped, etc. The smaller air outlet mesh holes can prevent external foreign matter from entering the cooking cavity 411 through the air outlet 412, and can sort out the airflow, make the airflow flow out evenly, reduce airflow turbulence, and make the exhaust smoother.
