Description

Technical Field

[0001] This application relates to the field of kitchen utensils, and in particular to a cooking apparatus. Background Technology

[0002] In related technologies, the enclosed structure of steam ovens, due to their use in cooking, lacks an effective design for intuitive visualization of the heating status, making it difficult to know the internal heating information. Specifically, it is impossible to directly observe the dynamic characteristics of the flame closely related to heating, such as flame size and intensity. This lack of visualization of the heating status makes it difficult to accurately grasp the fit between the heating level and the cooking requirements of the food. For dishes that require high heat control, operation can only be based on limited experience and fixed program settings, making it impossible to flexibly adjust according to the actual heating situation, thus affecting the final cooking quality of the food and limiting the autonomy of the cook. Therefore, how to enhance the visualization of the heating status of steam ovens is the technical problem that this application aims to solve. Summary of the Invention

[0047] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0048] The following is for reference. Figures 1-5 A cooking apparatus 100 according to an embodiment of this application is described.

[0049] The cooking apparatus 100 according to an embodiment of this application is characterized in that it includes a housing 1 and a burner 2. The housing 1 has a cooking chamber 11 and a combustion chamber 12 that are connected to each other. The burner 2 is disposed in the housing 1 and located in the combustion chamber 12. The burner 2 is used to communicate with gas and to burn the gas in the combustion chamber 12. The housing 1 has a first observation window 141. At least a portion of the first observation window 141 is located on the top of the burner 2 and is used to observe the flame of the burner 2.

[0050] Currently, in related technologies, steam ovens, due to their enclosed structure, lack effective designs that allow for intuitive visualization of the heating status during the cooking process, making it difficult to know the internal heating information.

[0051] By setting a first observation window 141, at least a portion of which is located on top of the burner 2, when the cooking device 100 is running and the burner 2 burns gas to produce a flame in the combustion chamber 12, the flame of the burner 2 can be directly observed through the first observation window 141, which is located on top of the burner 2. The size, color, and stability of the flame can be observed. It can be understood that a larger and brighter flame indicates higher combustion intensity and greater heating power; a smaller and paler flame indicates relatively weaker heating. By observing the flame state in real time, the cooking device 100 can be monitored during the cooking process. In the heating state, when performing operations requiring precise temperature control, the size of the observed flame can be used to determine whether the heating is excessive or insufficient, thereby adjusting the gas supply or cooking time in a timely manner. For stewing food, the flame condition can also be used to ensure that the temperature inside the pot remains stable within a suitable range, avoiding reliance on preset programs or guesswork based solely on experience. The cooking process can be controlled based on the intuitively visible flame information, enhancing the control over the heating state of the cooking device 100, effectively improving the autonomy and flexibility of cooking, and ultimately achieving a significant enhancement in the visualization of the heating state of the cooking device 100. This allows for better fulfillment of diverse cooking needs and improved cooking results and experience.

[0052] According to some embodiments of the present application, the cooking apparatus 100 includes a housing 1, a housing body 13 and a partition plate 14. The partition plate 14 is disposed inside the housing body 13 and divides the housing body 13 into a cooking chamber 11 and a combustion chamber 12. A first observation window 141 is formed on the partition plate 14.

[0053] By setting the partition plate 14, the cooking chamber 11 and the combustion chamber 12 are separated, ensuring the independence and stability of the cooking environment. Water vapor, oil stains, etc. generated during cooking will not easily enter the combustion chamber 12 and affect the normal operation of the burner 2. At the same time, the exhaust gas generated by combustion will not mix into the cooking chamber 11 in large quantities and contaminate the food. The first observation window 141 opened on the partition plate 14 allows the burner 2 in the combustion chamber 12 to work and generate a flame when the cooking device 100 is started. The state of the flame reflects the intensity and state of heating. The flame of the burner 2 can be observed through the first observation window 141 on the partition plate 14. There is no need to find other angles or worry about not being able to see the flame due to structural obstruction. The cooking process can be adjusted according to the observed flame state in real time, improving the accuracy and success rate of cooking, enhancing the operability and experience during use, and meeting the requirements of precise control of heating state for different dishes.

[0054] According to some embodiments of the present application, the cooking apparatus 100 includes a partition plate 14 comprising a partition plate body 142 and a cover plate 143. The partition plate body 142 has an observation hole 1421 that connects the cooking chamber 11 and the combustion chamber 12. The cover plate 143 is disposed on the partition plate body 142 and covers the observation hole 1421. The cover plate 143 has a partially perforated through hole 1432 and / or the cover plate is constructed as a transparent part.

[0055] like Figure 2-3 As shown, Figure 2 A schematic diagram of a structure in which a single cover plate 142 covers the observation hole 1421 and a through hole 1432 is provided on the cover plate 142; Figure 3 The diagram shows a structure in which a single cover plate 142 covers the observation hole 1421 and the cover plate 142 is constructed as a transparent part. The partition plate 142 firstly serves as a divider, separating the interior of the cabinet body 13 into two functional areas: the cooking chamber 11 and the combustion chamber 12. This effectively ensures the orderliness of the cooking environment, prevents the food, water vapor, etc. in the cooking chamber 11 from interfering with the combustion in the combustion chamber 12, prevents a large amount of water vapor generated during cooking from flowing into the combustion chamber 12 and affecting the normal combustion of the burner 2, and also prevents exhaust gases generated during combustion from directly entering the cooking chamber 11 and affecting the quality of the food.

[0056] The partition plate body 142 has an observation hole 1421 that connects the cooking chamber 11 and the combustion chamber 12, providing a channel for observing the flame and other conditions in the combustion chamber 12. The cover plate 143 covers the observation hole 1421 to provide protection and prevent foreign objects from entering the combustion chamber 12 or entering the cooking chamber 11 from the combustion chamber 12 through the observation hole 1421, thus maintaining a relatively stable and clean environment in the two impeller chambers 41.

[0057] Furthermore, the cover plate 143 may have partially perforated through holes 1432, through which the flame condition of the burner 2 inside the combustion chamber 12 can be observed. The size and stability of the flame can be observed through the through holes 1432. The cover plate 143 may also be constructed as a transparent part, providing a clearer and more complete viewing port, allowing observation of the flame condition of the burner 2 inside the combustion chamber 12. The transparent cover plate 143 ensures the feasibility of observation while limiting the possibility of foreign objects passing through, enabling control of cooking based on the actual observed flame conditions. The working state of the burner 2 can be flexibly adjusted according to the cooking requirements of different dishes, thereby improving the accuracy and success rate of cooking, optimizing the cooking effect, and further enhancing the operating experience and overall satisfaction when using the cooking device 100. Cooking no longer blindly relies on preset programs, but can be combined with actual observation to exert more autonomy.

[0058] According to some embodiments of the present application, a cooking apparatus 100 has a cover plate 143 having a first limiting connector 1431 formed thereon, and a partition plate body 142 having a second limiting connector 1423 that limits and cooperates with the first limiting connector 1431 to restrict the movement of the cover plate 143 relative to the partition plate body 142.

[0059] Through the limiting cooperation of the first limiting connector 1431 and the second limiting connector 1423, the cover plate 143 can be fixed on the partition plate body 142, covering the observation hole 1421. During the daily use of the cooking device 100, it is subjected to various external forces such as handling, opening and closing the cabinet door, and internal airflow impact during cooking. When the cabinet door of the cooking device 100 is opened or closed, a certain vibration and impact force will be transmitted to the inside of the cabinet 1. Through the limiting cooperation, the cover plate 143 is prevented from shifting, which may lead to the exposure of part of the observation hole 1421, making it easier for foreign objects to enter the combustion chamber 12 or the cooking chamber 11, and disrupting the relatively stable and clean environment inside the two impeller chambers 41. Through the limiting cooperation of the first limiting connector 1431 and the second limiting connector 1423, the cover plate 143 continues to effectively protect the observation hole 1421, maintains a reasonable separation state between the cooking chamber 11 and the combustion chamber 12, and ensures the normal operation of the cooking device 100 and the good order of the internal environment.

[0060] In subsequent use, if the cover plate 143 is damaged and needs to be replaced, the new cover plate 143 can be disassembled and installed with the help of the first limiting connector 1431 and the second limiting connector 1423, which reduces the difficulty and cost of maintenance, making the entire cooking device 100 easier to manage and maintain during its service life and extending its service life.

[0061] According to some embodiments of the present application, the cooking apparatus 100 has a first limiting connector 1431 and a second limiting connector 1423 fixed by snap-fit, screw-fit and / or adhesive.

[0062] When the first limiting connector 1431 and the second limiting connector 1423 are fixed by snap-fit, the first limiting connector 1431 on the cover plate 143 needs to be aligned with the second limiting connector 1423 on the partition plate body 142, and then pressure is applied to make the two snap into place to complete the installation. The operation is simple and quick, without the need for complicated tools, which can effectively improve the assembly efficiency on the production line, reduce labor costs, and speed up the overall production progress. In subsequent use, if the cover plate 143 is damaged and needs to be replaced or cleaned and repaired, simply find the snap-fit ​​part, apply external force to make it disengage from the snap-fit ​​state, and the cover plate 143 can be easily removed, which greatly saves maintenance time and effort and facilitates the daily maintenance and management of the cooking device 100.

[0063] The first limiting connector 1431 and the second limiting connector 1423 are connected and fixed by rotating the threaded parts using a screw connection. When installing the cover plate 143, the position of the cover plate 143 can be adjusted according to the actual situation to ensure that the cover plate 143 can cover the observation hole 1421 of the partition plate body 142 and fit tightly with the partition plate body 142. The screw connection can provide a strong connection force, making the fixation between the cover plate 143 and the partition plate body 142 more firm and reliable. During the long-term use of the cooking device 100, facing the expansion and contraction of the components caused by frequent heat circulation, the vibration caused by placing heavy food during cooking, and the impact caused by repeated opening and closing of the door, the screw-connected limiting connector can maintain the stability of the cover plate 143 and prevent the cover plate 143 from shifting due to its strong connection characteristics.

[0064] The adhesive bonding method enables a seamless connection between the first limiting connector 1431 and the second limiting connector 1423, avoiding the tiny gaps that may exist in snap-fit ​​or screw-fit connections. This better prevents impurities such as water vapor and oil stains in the cooking chamber 11 from penetrating into the combustion chamber 12 through the connection part and affecting the normal operation of the burner 2. At the same time, it can also prevent exhaust gas generated in the combustion chamber 12 from entering the cooking chamber 11 in reverse and contaminating the food.

[0065] The cooking apparatus 100 according to some embodiments of this application further includes a limiting frame 1422, the limiting frame 1422 being disposed on the partition plate body 142 and surrounding at least a portion of the outer periphery of the observation hole 1421, and a cover plate 143 being embedded in the limiting frame 1422.

[0066] The limiting frame 1422 is placed on the partition plate body 142 and surrounds at least part of the outer periphery of the observation hole 1421, while the cover plate 143 is embedded in the limiting frame 1422. The limiting frame 1422 provides a clear installation position reference for the cover plate 143. During the assembly of the cooking device 100, the cover plate 143 is embedded in the limiting frame 1422 along its contour, which ensures that the cover plate 143 accurately covers the observation hole 1421, avoiding positional deviations that may occur due to manual operation. This ensures the normal realization of the subsequent visual flame observation function and a good separation state between the cooking chamber 11 and the combustion chamber 12, making the product quality and performance more stable and reliable.

[0067] When the cooking device 100 is subjected to various external forces during daily use, the limiting frame 1422 can effectively enhance the stability of the cover plate 143. Because the limiting frame 1422 provides a surrounding constraint on the cover plate 143, it can better resist these external forces and remain fixed above the observation hole 1421, preventing easy displacement or loosening. This maintains effective coverage of the observation hole 1421 by the cover plate 143, preventing foreign objects from entering the two impeller cavities 41, while also ensuring the stability of the viewing angle for observing the flame in the combustion chamber 12 through the cover plate 143. This facilitates accurate judgment of the heating status and precise control of the cooking process.

[0068] The limiting frame 1422 also protects the edge of the cover plate 143. During long-term use, the edge of the cover plate 143 may wear out or deform due to frequent external contact, slight friction with other parts, or thermal expansion and contraction. The limiting frame 1422 reduces the direct impact of external forces on the edge of the cover plate 143, extending the service life of the cover plate 143. When cleaning the cooking appliance 100, even if the wiping tool accidentally touches the edge of the cover plate 143, the limiting frame 1422 protects the cover plate 143 from damage, thereby reducing the frequency of replacement due to damage to the cover plate 143, lowering the cost of use, and improving the overall durability of the cooking appliance 100.

[0069] According to some embodiments of the present application, a cooking apparatus 100 has a plurality of through holes 1432 formed on a cover plate 143. The plurality of through holes 1432 are spaced apart on the cover plate 143, and the through holes 1432 are constructed as strip holes, round holes or polygonal holes.

[0070] Understandably, the spaced arrangement of multiple through holes 1432 allows for a relatively uniform distribution of viewing angles when observing the flame inside the combustion chamber 12 through the cover plate 143, avoiding local blind spots or overly concentrated observation points.

[0071] The through hole 1432 can be constructed as a strip hole, a round hole, or a polygonal hole. When the through hole 1432 is constructed as a strip hole, the strip hole can extend in any direction. Compared with shapes such as round holes, the strip hole can provide a wider field of view in the direction of extension. When the through hole 1432 is constructed as a round hole, the shape of the round hole has mechanical stability. The opening of a round hole on the cover plate 143 has a relatively small impact on the overall structural strength of the cover plate 143 compared with other shapes. The circumferential stress distribution of the round hole is more uniform. When subjected to external force, it can distribute the pressure more evenly, making the cover plate 143 less prone to cracking or other damage due to local stress concentration. When the through hole 1432 is constructed as a polygonal hole, since the polygonal hole has multiple sides and corners, it provides more diverse observation angles. The positions of different sides and corners can be used to observe the flame in the combustion chamber 12 from multiple different perspectives, increasing the flexibility of observation.

[0072] According to some embodiments of the cooking apparatus 100 of this application, the partition plate 14 includes: a partition plate body 142; a microporous plate 15 and a cover plate 143. An observation hole 1421 is formed on the partition plate body 142. The microporous plate 15 is arranged with a plurality of microholes 151 that connect the cooking chamber 11 and the combustion chamber 12 and the microporous plate 15 covers the observation hole 1421. The cover plate 143 is disposed on the partition plate body 142 and covers the microporous plate 15. The cover plate 143 is constructed as a transparent element.

[0073] like Figure 4 As shown, Figure 4 This is a schematic diagram of a double-layer plate structure covering the observation hole 1421 with a cover plate 142 and a microporous plate 15. In some embodiments of this application, a double-layer plate structure is formed by the cover plate 143 and the microporous plate 15. The double-layer plate structures are superimposed and support each other. Compared with a single cover plate 143 or microporous plate 15, the overall structural strength is enhanced. It is understood that during the frequent heating and cooling cycles of the cooking device 100, thermal expansion and contraction will occur. The double-layer plate structure can better withstand this stress change and is less prone to deformation, cracking and other problems. After a long period of high-temperature cooking, if there is only a single-layer plate, it may warp due to stress concentration, affecting its covering effect on the observation hole 1421 and the overall protective performance. However, the double-layer plate structure can maintain a stable structural shape by means of mutual restraint and synergy, ensuring the normal operation of the cooking device 100 and the stable performance of its internal functions.

[0074] It should be noted that the micro-hole 151 is set in the double-layer plate structure for observing the combustion chamber. Since the micro-hole 151 is covered by the cover plate 143, the backflow of gas in the cooking chamber 11 can be avoided. Since the gas in the cooking chamber 11 is low-oxygen gas after being heated by the combustion chamber 12, covering the micro-hole plate 15 with the cover plate 143 can prevent the low-oxygen gas from flowing back into the combustion chamber 12 through the micro-hole 151, which would cause uneven heating of the combustion chamber and incomplete combustion. This can better achieve the sealing effect at the first observation window 141 and ensure the heating effect of the burner 2.

[0075] The cooking apparatus 100 according to some embodiments of this application further includes: a microwave unit disposed on the housing 1 and used to heat an object in the cooking cavity 11; wherein a plurality of microholes 151 are formed on the microporous plate 15, the plurality of microholes 151 are spaced apart on the microporous plate 15, wherein the diameter of the microholes 151 is d and satisfies: 0.1mm≤d≤8mm.

[0076] The microwave unit is mounted on the housing 1 to heat the object inside the cooking cavity 11, providing an additional heating method for cooking and enriching the functions of the cooking device 100. Furthermore, multiple micro-holes 151 are formed on the micro-perforated plate 15, and these micro-holes 151 are spaced apart on the micro-perforated plate 15. When the size of the micro-hole 151 is less than 8mm, the microwaves are confined by the size of the micro-hole 151, thus confining the microwaves within the cooking device 100 and preventing magnetic leakage. This ensures the safety of the surrounding environment when the cooking device 100 is heated using the microwave unit, allowing for safe use and avoiding health risks caused by microwave leakage. While ensuring safety, the micro-holes 151 with a diameter of not less than 0.1mm allow observation of the flame of the burner 2 inside the combustion cavity 12, meeting the need for visual observation of the heating status during cooking. This facilitates timely adjustment of the burner 2's operating status, such as gas flow and flame size, based on the flame conditions, thereby controlling the cooking temperature.

[0077] The cooking apparatus 100 according to some embodiments of this application further includes a cover plate 3, which is disposed between the partition plate 14 on the side away from the cooking chamber 11 and the partition plate 14 to define a combustion chamber 12. The partition plate 14 has an air outlet 31 that connects the cooking chamber 11 and the combustion chamber 12. The air outlet 31 is located at the top of the first observation window 141.

[0078] The cover plate 3 is placed on the side of the partition plate 14 away from the cooking chamber 11. Together with the partition plate 14, it defines the combustion chamber 12, creating a relatively independent and stable environment for the normal operation of the burner 2. This makes the combustion process less susceptible to interference from external factors, avoids the disorderly inflow of external air affecting the mixing ratio of gas and air, ensures that the burner 2 can burn gas stably and efficiently, maintain a stable flame state, and provide a reliable and continuous heat source for cooking. Moreover, the independent combustion chamber 12 can also reduce the outward transmission of combustion noise to a certain extent, making the cooking device 100 quieter during operation and improving the user experience in the kitchen environment.

[0079] The partition plate 14 has an air outlet 31 that connects the cooking chamber 11 and the combustion chamber 12, allowing air from the cooking chamber 11 to enter the combustion chamber 12. It is understood that when the cooking device 100 is started, the burner 2 in the combustion chamber 12 ignites the gas, and the heat in the combustion chamber 12 is high. In order to avoid the high-heat air blowing directly onto the food in the cooking chamber 11 and causing it to burn, the air outlet 31 is set to blow air from the cooking chamber 11 to the combustion chamber 12. This can draw out the cold air in the cooking chamber 11 when the cooking device 100 is started and mix it with the hot air in the combustion chamber 12, avoiding local overheating, and also preparing for the subsequent redistribution of heat.

[0080] By placing the air outlet 31 at the top of the first observation window 141, visual interference caused by airflow affecting the observation window is avoided. Airflow may carry water vapor, smoke, etc., which can easily block the observation window and affect the observation effect on the flame in the combustion chamber 12 through the first observation window 141. By placing the air outlet 31 at the top of the first observation window 141, the lower temperature airflow in the cooking chamber 11 enters the combustion chamber 12 through the air outlet 31 during its ascent and is reheated to a higher temperature airflow. The air outlet 31 forms an exhaust channel with a fast airflow speed. The water vapor and smoke carried in the airflow have little impact on the first observation window 141 and will not interfere with normal observation. This ensures that the size, color, and other status information of the flame can be clearly and stably seen, so as to adjust the cooking process based on the observation results.

[0081] The cooking apparatus 100 according to some embodiments of this application further includes a fan housing 4 and a fan 5. The fan housing 4 is connected to the partition plate 14 and covers the outside of the cover plate 3. A fan cavity 41 communicating with the cooking cavity 11 is formed between the fan housing 4 and the cover plate 3. An airflow channel communicating with the fan cavity 41 is formed on the cover plate 3. The fan 5 is rotatably disposed in the fan cavity 41. An air inlet 51 communicating with the fan cavity 41 is formed on the partition plate 14.

[0082] An airflow channel communicating with the impeller cavity 41 is formed on the cover plate 3. Since the impeller 5 is rotatably disposed in the impeller cavity 41, when the impeller 5 is working, it will generate a directional airflow in the impeller cavity 41. This airflow can draw out the gas from the combustion chamber 12 through the rotation of the impeller 5 and enter the impeller cavity 41 through the airflow channel. Since the air outlet 31 is the connection between the cooking chamber 11 and the combustion chamber 12, a pressure difference will be formed around the air outlet 31. This pressure difference will drive air from the cooking chamber 11 through the air outlet 31 into the combustion chamber 12, thereby improving the airflow efficiency between the cooking chamber 11 and the combustion chamber 12.

[0083] Furthermore, the partition plate 14 has an air inlet 51 that communicates with the impeller cavity 41. The reheated airflow in the impeller cavity 41 can be transported to the cooking cavity 11 through the air inlet 51. When the cooking device 100 is started, the cold air in the cooking cavity 11 is drawn out of the cooking cavity 11 and mixed with the hot air in the combustion cavity 12. The hot air in the combustion cavity 12 is connected to the impeller cavity 41 through the airflow channel and then enters the impeller cavity 41 through the airflow channel. The gas achieves the mixing of hot and cold air through the combustion cavity 12 and the impeller cavity 41, avoiding the direct entry of directly heated air into the cooking cavity 11, which can easily lead to scorching. At the same time, it accelerates the heat circulation between the cooking cavity 11, the combustion cavity 12 and the impeller cavity 41, promotes the thermal balance in the entire cooking device 100, and can more quickly and evenly distribute the heat generated by the burner 2 in the cooking cavity 11, improve the heat utilization efficiency, reduce the temperature unevenness during the cooking process, and help improve the cooking quality and shorten the cooking time.

[0084] It should be noted that the air inlet 51 can be located on at least one side of the air outlet 31 in the width direction.

[0085] The cooking apparatus 100 according to some embodiments of this application further includes a protective shell 6 and a fan 7. The protective shell 6 is disposed on the outside of the impeller housing 4 and defines a cooling cavity 61. The fan 7 is housed in the cooling cavity 61 and the output shaft of the fan 7 is connected to the impeller 5.

[0086] The output shaft of the fan 7 is connected to the impeller 5. The fan 7 drives the rotation of the impeller 5. The protective shell 6 is located outside the impeller housing 4, providing physical protection for the fan 7 and preventing damage to the fan 7 and its related components. This ensures the fan 7 can operate normally and stably, thereby guaranteeing the normal operation of the entire cooking device 100. The protective shell 6 defines a cooling cavity 61 for housing the fan 7. During operation, the fan 7 generates heat due to the rotation of the impeller 5 and the operation of the motor. If the heat cannot be dissipated in time, it will accumulate inside the fan 7, causing the fan 7 temperature to rise. Excessive temperature will adversely affect the performance of the fan 7, potentially reducing motor efficiency and shortening motor lifespan. The cooling cavity 61 provides cooling protection for the fan 7. The air can flow inside, forming a relatively independent heat dissipation space. When the fan 7 is working, its rotation will drive the air flow in the cooling chamber 61. At the same time, due to the operation of other components inside the cooking device 100, such as the airflow disturbance generated by the burner 2, the air inside and outside the cooling chamber 61 may also be exchanged. Through this air flow, the heat generated by the fan 7 can be carried out of the cooling chamber 61 with the air and dissipated to the external environment of the cooking device 100, thereby effectively reducing the temperature of the fan 7, maintaining the fan 7 within a more suitable operating temperature range, ensuring the stable performance of the fan 7, extending the service life of the fan 7, and thus improving the reliability and durability of the entire cooking device 100.

[0087] According to some embodiments of the present application, the cooking apparatus 100 has a smoke exhaust duct 131 formed on the housing body 13, which communicates with the cooking cavity 11, and the cooling cavity 61 communicates with the smoke exhaust duct 131.

[0088] The main body 13 of the cooking unit has a flue 131 that connects to the cooking chamber 11. During the cooking process, the fumes generated by steaming, baking and other operations in the cooking chamber 11 are discharged from the cooking device 100 through the flue 131. If the fumes cannot be discharged in time, they will accumulate in the impeller chamber 41, which will not only affect the cooking environment, but may also cause the food to be contaminated with odors and reduce the cooking quality. The connection of the flue 131 can ensure that these fumes have a smooth discharge channel, maintain the fresh air in the cooking device 100, ensure that the food is cooked in a relatively pure environment, and improve the cooking effect.

[0089] When the air inside the cooking device 100 changes volume due to heating, combustion, or other operations, the air pressure inside the impeller cavity 41 fluctuates. The connection between the exhaust duct 131 and the impeller cavity 41 can regulate the air pressure. When the burner 2 burns, the temperature of the combustion chamber 12 rises, and the air expands. If the exhaust duct 131 does not promptly discharge some of the air, the air pressure inside the combustion chamber 12 will rise, which may affect the normal combustion of the burner 2 or even cause pressure damage to the structure of the cooking device 100. The exhaust duct 131 can discharge excess air according to the changes in air pressure inside the impeller cavity 41, maintain the relative stability of the air pressure inside the impeller cavity 41, ensure the normal operation of the cooking device 100, and extend its service life.

[0090] The cooling chamber 61 is connected to the exhaust duct 131, allowing the heat generated by the fan 7 within the cooling chamber 61 to be carried out of the cooking appliance 100 along with the airflow from the exhaust duct 131. Normally, the heat generated by the fan 7 during operation is dissipated through the airflow within the cooling chamber 61. However, with the connection between the cooling chamber 61 and the exhaust duct 131, the airflow within the exhaust duct 131 creates a suction effect on the cooling chamber 61, accelerating the airflow and allowing the heat generated by the fan 7 to be expelled more quickly and efficiently. This further reduces the temperature of the fan 7, ensuring it operates within a more suitable temperature range, thus extending its lifespan, maintaining stable performance, and ensuring the normal operation of the cooking appliance 100. Because the cooling chamber 61 is connected to the exhaust duct 131, heat dissipation is integrated, eliminating the need for a separate, complex heat dissipation system for the fan 7. This reduces the need for additional ductwork, pipes, and other components, lowering production costs and making the product more competitive in the market. It also facilitates later maintenance and upkeep.

[0091] According to some embodiments of the present application, the cooking apparatus 100 has heat dissipation holes 132 formed on the body 13, and the protective shell 6 is open on the side facing the heat dissipation holes 132.

[0092] The heat dissipation holes 132 on the main body 13 of the cabinet provide an outlet channel for the heat dissipation inside the cooking device 100. During the operation of the cooking device 100, various components such as the fan 7 and the burner 2 will generate heat. This heat needs to be dissipated in time to maintain the normal operating temperature of the components. The protective shell 6 is open to the heat dissipation holes 132, so that the cooling chamber 61 inside the protective shell 6 and the external environment of the main body 13 of the cabinet are effectively connected through the heat dissipation holes 132. The heat generated by the fan 7 when it is working first accumulates in the cooling chamber 61. Due to the open design of the protective shell 6, the heat can be dissipated to the outside of the cooking device 100 through this channel and the heat dissipation holes 132, which can improve the service life of the fan 7.

[0093] According to some embodiments of the present application, the cooking apparatus 100 has a switch door 133 on the housing body 13 that can open and close the cooking cavity 11, and a second observation window 1331 is formed on the switch door 133 that is directly opposite to the first observation window 141.

[0094] Since the second observation window 1331 is directly opposite the first observation window 141, the flame of the burner 2 inside the combustion chamber 12 can be easily observed through the two directly opposite observation windows without opening the switch door 133. During cooking, when you want to check the flame, you can use the second observation window 1331, which is directly opposite the first observation window 141, to avoid frequently opening the switch door 133 and reduce the hot airflow inside the cooking device 100 caused by each door opening action, which would affect the cooking effect. The flame can be seen directly through the second observation window 1331 and the first observation window 141, without being obstructed by the opening and closing of the switch door 133 or its own structure. This ensures an unobstructed viewing angle, allowing you to see key information such as the size, color, and stability of the flame, so as to make reasonable adjustments to the cooking process.

[0095] The cooking apparatus 100 according to some embodiments of this application further includes a tray 111 disposed within the cooking cavity 11, and the tray 111 is constructed to be transparent.

[0096] Because the tray 111 is made of transparent material, it avoids obstructing the first observation window 141 and affecting the observation of the flame in the combustion chamber 12. The transparent tray 111 also allows for better light transmission during cooking, enabling users to observe both the food and flame conditions simultaneously. Since the tray 111 is transparent, it does not obstruct the first observation window 141. In front of the cooking device 100, users can see the real-time changes of the food in the cooking chamber 11 through the transparent tray 111 and the flame in the combustion chamber 12 through the observation window, achieving more comprehensive and precise control over the cooking process.
