Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of household appliances, and in particular to a steam oven. BACKGROUND

[0002] In modern kitchen appliances, steam ovens combine the functions of steam and baking, allowing for the preservation of food moisture while achieving a crispy exterior effect. Their versatility and convenience have gained widespread popularity.

[0003] Currently, due to the use of a large number of silica gel parts and injection molded parts inside the steam oven, these materials are prone to aging and loss of function under high temperature conditions. To ensure the long-term stability and safety of the equipment, the steam oven usually limits the maximum temperature to 230°C.

[0004] Although a temperature of 230°C is sufficient to meet the cooking needs of most ordinary food, when dealing with large pieces of meat, this temperature limit will result in excessively long cooking times and poor final cooking taste, failing to achieve the desired texture and flavor, severely affecting the cooking experience. INVENTION CONTENTS

[0005] Embodiments of the present application provide a steam oven that can raise the center temperature of the inner container when the design temperature is 230°C, quickly baking the food, thereby shortening the cooking time and improving the cooking efficiency and experience.

[0006] In a first aspect, embodiments of the present application provide a steam oven, comprising:

[0007] a box body, the box body having an inner container cavity formed inside, the box body having an opening communicating with the inner container cavity;

[0008] a door body rotatably arranged on the box body, the door body being used to close the opening;

[0009] a heating fan arranged on the bottom wall of the inner container cavity on the side away from the opening;

[0010] an arc-shaped glass arranged on the door body, the arc-shaped glass being opposite to the bottom wall of the inner container cavity when the door body closes the opening of the inner container cavity;

[0011] from the center to the edge side of the arc-shaped glass, the distance between the arc-shaped glass and the bottom wall in the depth direction of the inner container cavity gradually decreases;

[0012] the heating fan is configured to: suck air in the center region of the inner container cavity into heating to generate hot air along the depth direction perpendicular to the inner container cavity; and the generated hot air is transmitted to the opening of the inner container cavity along the periphery of the inner container cavity after passing through the bottom wall;

[0013] The arc-shaped glass is configured to reflect and guide the hot air blown from the periphery of the inner cavity to the central region of the inner cavity.

[0014] In this way, by designing the arc-shaped glass on the door body and arranging the arc-shaped glass opposite to the bottom wall of the inner cavity, the arc-shaped glass can effectively reflect heat and gather hot air in the required direction, can reflect and guide the hot air blown from the periphery of the inner cavity to the central region of the inner cavity, can make the temperature of the central region of the inner cavity significantly rise, and can make the heat emitted by the heating fan be concentrated to the food, so that the ideal heating effect is achieved. In the case of a design temperature of 230 DEG C, the temperature of the central region of the inner cavity can reach the effect of high-temperature baking of a traditional oven, so that the food is quickly baked, and the cooking efficiency and effect are improved. Meanwhile, by using the arc-shaped glass to reflect heat, the heat transferred to the glass can be effectively reduced, the temperature rise of the door body is reduced, the customer experience is improved, and the energy consumption of the whole machine is reduced.

[0015] In some embodiments of the present application, the steam oven further comprises a wind guide, the wind guide is arranged on the door body around the opening of the inner cavity, and is arranged to be inclined to the bottom wall of the inner cavity along the vertical direction of the depth of the inner cavity and from the center to the edge of the inner cavity.

[0016] In this way, by arranging the wind guide around the opening of the inner cavity and filling the inclined wind guide at the right angle where the door body contacts the inner cavity, the vortex generated by the hot air blown from the periphery of the inner cavity at this position can be reduced, the path of the hot air flow is optimized, the heat is prevented from being retained and inefficiently circulated at the corner, so that the heat loss is reduced, and the overall energy consumption is reduced. Moreover, the inclined wind guide helps the hot air to flow more smoothly through the inner cavity, improves the efficiency of the hot air circulation, and thus improves the heating efficiency. The inclined design of the wind guide can more effectively guide the hot air to the central region of the inner cavity, and helps to form a more effective hot air circulation system.

[0017] In some embodiments of the present application, the side close to the middle of the wind guide is connected to the side away from the middle of the arc-shaped glass along the vertical direction of the depth of the inner cavity and from the center to the edge of the inner cavity.

[0018] In this way, by connecting the wind guide and the arc-shaped glass, a continuous hot air guiding path is formed, the hot air flow can be more effectively guided, and the hot air is ensured to enter the central region of the inner cavity along the predetermined path, so that the utilization efficiency of the hot air is improved. The connection of the wind guide and the arc-shaped glass reduces the gap and leakage point in the hot air flow, and helps to form a closed hot air circulation system, so that the loss of the hot air in the flow process is reduced.

[0019] In some embodiments of the present application, the arc-shaped glass comprises a LOW-E glass.

[0020] In this way, the LOW-E glass has excellent heat reflection performance, can effectively reflect infrared heat radiation back into the inner cavity, helps to reduce heat loss, reduces energy consumption, improves thermal efficiency, and makes food reach the required cooking temperature more quickly. The heat reflection characteristics of the LOW-E glass can also reduce the temperature rise of the glass surface, reduce the temperature outside the steaming oven, improve the safety of the user, and reduce the risk of burns caused by touching the overheated surface.

[0021] In some embodiments of the present application, the box comprises:

[0022] The inner cavity top plate;

[0023] The inner cavity surrounding plate is located below the inner cavity top plate and connected to the two side walls opposite to the inner cavity top plate;

[0024] The inner cavity back plate connects the back side of the inner cavity top plate and the back side of the inner cavity surrounding plate;

[0025] The inner cavity top plate, the inner cavity surrounding plate and the inner cavity back plate form an inner cavity, the inner cavity back plate forms the bottom wall of the inner cavity, and the heating fan is arranged on the inner cavity back plate.

[0026] In this way, by tightly connecting the inner cavity top plate, the inner cavity surrounding plate and the inner cavity back plate, a solid inner cavity structure is formed, improving the overall stability and durability of the box, which can withstand high temperature and mechanical stress, prolonging the service life of the equipment. The heating fan installed on the inner cavity back plate can effectively transfer heat to the entire inner cavity, and the heat can be more evenly distributed in the cavity, ensuring that the food is evenly heated during cooking and improving the cooking effect.

[0027] In some embodiments of the present application, the heating fan comprises:

[0028] The fan is arranged on the inner cavity back plate, and the fan is used to suck air in the center area of the inner cavity to guide the air to the opening side;

[0029] The heating element is arranged on the inner cavity back plate, and the heating element is used to heat the passing air to generate hot air.

[0030] In this way, the heating element is directly arranged on the inner container back plate, which can directly and quickly heat the passing air, improving the efficiency of heat transfer. The arrangement of the fan enables the air in the inner container cavity to be effectively sucked in and circulated, ensuring uniform distribution of hot air in the cavity, avoiding local overheating or undercooking, and improving the cooking quality of food. Through the cooperation of the heating element and the fan, the hot air can uniformly wrap the food, ensuring that the outside is crispy and the inside is fully cooked, improving the texture and flavor of the food, and meeting the user's demand for high-quality cooking effect. By adjusting the power of the heating element and the speed of the fan, the user can flexibly control the temperature and air speed in the inner container cavity to adapt to different types of food and cooking methods, providing greater operational flexibility.

[0031] In some embodiments of the present application, the fan comprises:

[0032] The driving motor is arranged on the inner container back plate.

[0033] The fan blade is connected to the driving shaft of the driving motor and is located on the side of the inner container back plate facing the inner container cavity.

[0034] In this way, the driving motor drives the fan blade to rotate, effectively sucking and circulating the air in the inner container cavity, achieving efficient air circulation and ensuring uniform distribution of hot air in the inner container cavity, improving the uniform heating effect of food. Since the driving motor can quickly adjust the speed of the fan blade, the user can quickly change the air flow speed in the inner container cavity, so that the steaming oven can quickly adapt to different cooking needs, improving the flexibility and accuracy of temperature control.

[0035] In some embodiments of the present application, the heating element is arranged around the fan on the inner container back plate.

[0036] In this way, the layout of the heating element around the fan ensures that the air sucked in by the fan is heated, ensuring that the air blown out is always hot, thereby improving the efficiency and uniformity of the hot air. Since the heating element directly surrounds the fan, heat can be quickly transferred to the flowing air, shortening the response time of heating, so that the steaming oven can reach the set temperature faster, improving the cooking efficiency. The ring-shaped heating element ensures that heat is evenly distributed in the entire air flow, reducing areas of uneven temperature, which helps to evenly cook food and avoids local overheating or undercooking.

[0037] In some embodiments of the present application, the heating fan further comprises a wind guide cover connected with the inner container back plate and forming a wind guide cavity between the wind guide cover and the inner container back plate, the heating element is arranged in the wind guide cavity, the fan is located in the wind guide cavity, the wind guide cover is provided with an air inlet and an air outlet, and the air inlet and the air outlet are in communication with the inner container cavity.

[0038] When the drive motor drives the fan blades to rotate, the fan blades can draw air into the air guide cavity through the air inlet, and transfer the hot air in the air guide cavity to the inner cavity through the air outlet.

[0039] In this way, the air guide hood and the inner liner back panel together form an air guide cavity, providing a closed and optimized path for the flow of hot air. The design of the air intake and exhaust vents ensures that air is efficiently guided into the inner liner cavity after passing through the heating element. The heating element, located within the air guide cavity, directly heats the intake air, ensuring that the hot air reaches the ideal temperature before entering the inner liner cavity, improving heat transfer efficiency and shortening cooking time. Guided by the air guide hood, the hot air is evenly distributed within the inner liner cavity, reducing areas of uneven temperature and promoting uniform cooking, preventing localized overheating or uncooking.

[0040] In some embodiments of this application, the inner liner back plate is provided with an air guide groove, which extends along the direction of the air intake to the air outlet.

[0041] In this way, the design of the air guide duct provides a clear path for the airflow within the air guide cavity, guiding the air from the intake to the outlet. By optimizing the flow path, airflow resistance is reduced, and air circulation efficiency is improved. Simultaneously, guided by the air guide duct, the air can better contact the heating element during its flow, thereby improving heat transfer efficiency. The efficient hot air flow and heating system reduce ineffective heat loss and improve energy utilization. The air guide duct design also helps to smooth airflow, reducing noise and vibration caused by air turbulence, and improving the quietness and stability of the equipment's operation.

[0061] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0062] In modern kitchen appliances, steam ovens can combine the functions of steam and baking, retain the moisture of food while achieving the crisp effect on the outside, and are widely welcomed for their versatility and convenience.

[0063] At present, due to the use of a large number of silica gel parts and injection molding parts inside the steam oven, these materials are prone to aging and loss of function under high temperature conditions. In order to ensure the long-term stability and safety of the equipment, the steam oven usually limits the maximum temperature to 230℃.

[0064] Although the temperature of 230℃ is sufficient to meet the cooking needs of most ordinary food, when dealing with large meat, this temperature limit will lead to too long cooking time and poor final cooking taste, which seriously affects the cooking experience.

[0065] After repeated thinking and verification, the inventor found that if an arc-shaped glass is arranged on the door body, the hot air blown by the back fan is gathered into an area at the center of the inner container by the guiding effect of the arc-shaped glass, so that the temperature of this area rises rapidly and is higher than other positions, which promotes the heat emitted by the heating pipe to be concentrated and transmitted to the food, improves the efficiency and effect of roasting food, and achieves the purpose of energy saving.

[0066] Figure 1 A structural schematic diagram of the steam oven provided by the embodiment of the present application is shown. Figure 2 A structural schematic diagram of the steam oven provided by the embodiment of the present application is shown. Figure 1 A sectional view of the steam oven is shown. Figure 3 A sectional view of the steam oven is shown. Figure 1 A sectional view of the steam oven is shown.

[0067] As shown in Figure 1 , Figure 2 , Figure 3 The steam oven 100 provided by the embodiment of the present application is used for steaming or baking food. The steam oven 100 comprises a box body 10, a door body 20 and a heating fan 30. The box body 10 is internally formed with an inner container cavity 101, and the box body 10 is provided with an opening communicating with the inner container cavity 101. The door body 20 is rotatably arranged on the box body 10, and the door body 20 is used for closing the opening. The heating fan 30 is arranged on the box body 10. The heating fan 30 is used for heating air to generate hot air for baking.

[0068] The box body 10 is further provided with a steam generator for providing steam to steam cook food.

[0069] As shown in Figure 2 and Figure 3 The heating fan 30 is arranged on the bottom wall of the inner container cavity 101 on the side away from the opening.

[0070] The door body 20 is provided with an arc-shaped glass 21. When the door body 20 closes the opening of the inner container cavity 101, the arc-shaped glass 21 is opposite to the bottom wall of the inner container cavity 101, i.e. the arc-shaped glass 21 is arranged opposite to the heating fan 30.

[0071] From the center to the edge of the arc-shaped glass 21, the distance between the arc-shaped glass 21 and the bottom wall in the depth direction of the inner container cavity 101 gradually decreases, i.e. in the middle part of the opening of the inner container cavity 101, the distance between the arc-shaped glass 21 and the bottom wall of the inner container cavity 101 is the largest.

[0072] Along the depth direction perpendicular to the inner liner cavity 101, the heating fan 30 is used to draw in and heat the air in the central area of ​​the inner liner cavity 101 to generate hot air. After passing through the bottom wall, the generated hot air is transmitted along the periphery of the inner liner cavity 101 towards the opening of the inner liner cavity 101, that is, the generated hot air is transmitted to the door body 20 side.

[0073] The curved glass 21 is used to reflect and guide the hot air blowing from all sides of the inner cavity 101 so that the hot air blows towards the center area of ​​the inner cavity 101, thereby baking the food in the center area of ​​the inner cavity 101.

[0074] In this way, by designing an arc-shaped glass 21 on the door 20, so that the arc-shaped glass 21 is opposite to the bottom wall of the inner cavity 101, the arc-shaped glass 21 can effectively reflect heat and concentrate hot air in the required direction. It can reflect and guide the hot air blowing from all sides of the inner cavity 101, so that the hot air is concentrated and blown towards the center area of ​​the inner cavity 101, so that the temperature at the center of the inner cavity 101 rises significantly, and the heat generated by the heating fan 30 can be concentrated and transferred to the food to achieve the ideal heating effect.

[0075] With a design temperature of 230℃, the center temperature of the inner cavity 101 can reach an effect equivalent to high-temperature baking in a traditional oven, thus quickly cooking food and improving cooking efficiency and results. At the same time, the curved glass 21 reflects heat, effectively reducing heat transfer to the glass and lowering the temperature rise of the door 20, improving the customer experience while reducing the overall energy consumption of the machine.

[0076] Figure 4 for Figure 1 One of the structural diagrams of the door of the steam oven shown. Figure 5 for Figure 1 The second schematic diagram of the door structure of the steam oven shown.

[0077] Please also refer to Figure 4 and Figure 5 In some embodiments of this application, the steam oven 100 further includes an air guide 22, which is disposed on the door 20 surrounding the opening of the inner cavity 101. Along a direction perpendicular to the depth of the inner cavity 101 and from the center to the edge of the inner cavity 101, the air guide 22 is inclined towards the bottom wall of the inner cavity 101. The air guide 22 is used to guide the hot air blowing from all sides of the inner cavity 101, directing it towards the curved glass 21.

[0078] In this way, by arranging the air guide 22 around the opening of the inner cavity 101, filling the air guide 22 arranged at an angle at the right angle where the door body 20 contacts the inner cavity 101, the vortex generated by the hot air blown from the heating fan 30 around the inner cavity 101 at this position can be reduced, the path of the hot air flow is optimized, and the stagnation and ineffective circulation of heat at the corner are avoided, thereby reducing heat loss and overall energy consumption. And the air guide 22 designed at an angle helps the hot air to flow more smoothly through the inner cavity 101, improving the efficiency of the hot air circulation, thereby improving the heating efficiency. The inclined design of the air guide 22 can more effectively guide the hot air to the central area of the inner cavity 101, helping to form a more effective hot air circulation system.

[0079] In some embodiments of the present application, the air guide 22 is connected to the side of the arc-shaped glass 21 away from the middle along the direction perpendicular to the depth of the inner cavity 101 and from the center to the edge of the inner cavity 101. That is, there is no other structure between the air guide 22 and the arc-shaped glass 21, and they are directly connected.

[0080] In this way, by connecting the air guide 22 and the arc-shaped glass 21, a continuous hot air guiding path is formed, which can more effectively guide the hot air flow and ensure that the hot air enters the central area of the inner cavity 101 along the predetermined path, thereby improving the utilization efficiency of the hot air. The connection of the air guide 22 and the arc-shaped glass 21 reduces the gaps and leakage points in the hot air flow, helping to form a closed hot air circulation system and reducing the loss of hot air during the flow process.

[0081] In some embodiments of the present application, the arc-shaped glass 21 comprises a LOW-E glass.

[0082] In this way, the LOW-E glass has excellent heat reflection performance and can effectively reflect infrared heat radiation back into the inner cavity 101, helping to reduce heat loss, reduce energy consumption, improve thermal efficiency, and make food reach the required cooking temperature more quickly. The heat reflection characteristics of the LOW-E glass can also reduce the temperature rise on the surface of the arc-shaped glass 21, reduce the temperature outside the steam oven 100, improve the safety of the user, and reduce the risk of burns caused by touching the overheated surface.

[0083] Please refer to Figure 1 and Figure 2In some embodiments of the present application, the box 10 includes a liner top plate 11, a liner surrounding plate 12, and a liner back plate 13. The liner surrounding plate 12 is located below the liner top plate 11 and is connected to the two side walls opposite the liner top plate 11, forming a box structure with openings on both sides. The liner back plate 13 is connected to the back side of the liner top plate 11 and the back side of the liner surrounding plate 12, thereby forming a liner cavity 101 between the liner top plate 11, the liner surrounding plate 12, and the liner back plate 13, and the liner back plate 13 forms the bottom wall of the liner cavity 101. The heating fan 30 is provided on the liner back plate 13.

[0084] In this way, by tightly connecting the liner top plate 11, the liner surrounding plate 12, and the liner back plate 13, a solid liner cavity 101 structure is formed, improving the overall stability and durability of the box 10, which can withstand high temperature and mechanical stress, prolonging the service life of the equipment. The heating fan 30 installed on the liner back plate 13 can effectively transfer heat to the entire liner cavity 101, and the heat can be more evenly distributed in the cavity, ensuring that the food is evenly heated during cooking and improving the cooking effect.

[0085] Figure 6 For Figure 1 Structure diagram of the heating fan of the steam oven shown in FIG. 1. Figure 7 For Figure 1 Structure diagram of the heating fan of the steam oven shown in FIG. 1. Figure 8 For Figure 1 Structure diagram of the heating fan of the steam oven shown in FIG. 1. Figure 9 For Figure 6 Structure diagram of the heating fan shown in FIG. 1 without a wind deflector. Figure 10 For Figure 6 Structure diagram of the heating fan shown in FIG. 1 without a wind deflector.

[0086] Please also refer to Figure 9 and Figure 10 In some embodiments of the present application, the heating fan 30 includes a heating element 31 and a fan 32. The heating element 31 is provided on the liner back plate 13, and the heating element 31 is used to heat the passing air to generate hot air. The fan 32 is provided on the liner back plate 13, and the fan 32 is used to suck air from the center area of the liner cavity 101 to guide the air to the opening side.

[0087] In this way, the heating element 31 is directly arranged on the inner container back plate 13, which can directly and quickly heat the passing air, improving the efficiency of heat transfer. The arrangement of the fan 32 enables the air in the inner container cavity 101 to be effectively sucked in and circulated, ensuring uniform distribution of hot air in the inner container cavity 101, avoiding local overheating or undercooking, and improving the cooking quality of food. Through the synergistic effect of the heating element 31 and the fan 32, hot air can uniformly wrap the food, ensuring that the outside is crispy and the inside is fully cooked, improving the texture and flavor of the food, and meeting the user's demand for high-quality cooking effect. Increasing the speed of the fan 32 can quickly remove the oil on the surface of the food through hot air, achieving the effect of air frying.

[0088] By adjusting the power of the heating element 31 and the speed of the fan 32, the user can flexibly control the temperature and air speed in the inner container cavity 101 to adapt to different types of food and cooking methods, providing greater operational flexibility. When the speed of the fan 32 is adjusted, the temperature of the central heating area of the inner container can be adjusted, and the air speed plus the temperature can achieve the functions of air frying and drying fruits and vegetables, which is better than the existing steam oven.

[0089] In some embodiments of the present application, the heating element 31 and the fan 32 are arranged in the middle part of the inner container back plate 13.

[0090] Please refer to Figure 7 In some embodiments of the present application, the fan 32 includes a driving motor 321 and a fan blade 322. The driving motor 321 is arranged on the inner container back plate 13. The fan blade 322 is connected to the driving shaft of the driving motor 321 and is located on the side of the inner container back plate 13 facing the inner container cavity 101.

[0091] In this way, the driving motor 321 drives the fan blade 322 to rotate, which can effectively suck in and circulate the air in the inner container cavity 101, achieving efficient air circulation and ensuring uniform distribution of hot air in the inner container cavity 101, improving the uniform heating effect of food. Since the driving motor 321 can quickly adjust the speed of the fan blade 322, the user can quickly change the air flow speed in the inner container cavity 101, so that the steam oven 100 can quickly adapt to different cooking needs, improving the flexibility and accuracy of temperature control.

[0092] In some embodiments of the present application, the driving motor 321 is located on the side of the inner container back plate 13 away from the inner container cavity 101, and the driving shaft of the driving motor 321 penetrates the inner container back plate 13.

[0093] Please refer to Figure 10 In some embodiments of the present application, the heating element 31 is arranged on the inner container back plate 13 around the fan blade 322.

[0094] In this way, the arrangement of the heating element 31 around the fan blade 322 allows the air to be heated after being drawn in by the fan blade 322, ensuring that the air blown out is always hot, thereby improving the efficiency and uniformity of the hot air. Since the heating element 31 directly surrounds the fan blade 322, heat can be quickly transferred to the flowing air, shortening the response time of heating and enabling the steaming oven 100 to reach the set temperature faster, thereby improving the cooking efficiency. The surrounding heating element 31 ensures that heat is evenly distributed in the entire air flow, reducing areas of uneven temperature and helping to evenly cook the food, avoiding local overheating or undercooking.

[0095] In some embodiments of the present application, the heating element 31 is a heating tube, thereby facilitating the surrounding arrangement.

[0096] Please also refer to Figure 6 and Figure 8 In some embodiments of the present application, the heating fan 30 further comprises a wind guide cover 33. The wind guide cover 33 is connected with the inner container back plate 13. The wind guide cover 33 and the inner container back plate 13 form a wind guide cavity 301 therebetween. The heating element 31 is arranged in the wind guide cavity 301, the fan blade 322 is located in the wind guide cavity 301, and the wind guide cover 33 is provided with an air inlet 331 and an air outlet 332. The air inlet 331 and the air outlet 332 are both in communication with the inner container cavity 101.

[0097] When the driving motor 321 drives the fan blade 322 to rotate, the fan blade 322 can draw air into the wind guide cavity 301 through the air inlet 331 and transmit the hot air in the wind guide cavity 301 to the inner container cavity 101 through the air outlet 332.

[0098] In this way, the wind guide cavity 301 formed by the wind guide cover 33 and the inner container back plate 13 provides a closed and optimized path for the flow of hot air. Through the design of the air inlet 331 and the air outlet 332, it is ensured that the air can be efficiently guided into the inner container cavity 101 after passing through the heating element 31. The heating element 31 is arranged in the wind guide cavity 301 and can directly heat the drawn-in air, so that the hot air reaches the ideal temperature before entering the inner container cavity 101, thereby improving the heat transfer efficiency and shortening the cooking time of the food. Through the guidance of the wind guide cover 33, the hot air can be evenly distributed in the inner container cavity 101, reducing areas of uneven temperature and helping to evenly cook the food, avoiding local overheating or undercooking.

[0099] In some embodiments of the present application, the air inlet 331 is arranged at the center of the wind guide cover 33 and opposite to the fan blade 322.

[0100] The air inlet 331 is located at the center of the air guide cover 33 and is arranged opposite the fan blades 322, which can maximize the use of the suction force of the fan blades 32, ensuring that air can be efficiently sucked into the air guide cavity 301, improving the efficiency of air flow. The design of the central air inlet 331 provides a symmetrical and uniform air flow path, so that air can be uniformly distributed to each part of the fan blades 322, reducing air flow resistance and improving the efficiency of hot air circulation. The design of the central air inlet 331 and the opposite fan blades 322 helps to smooth air flow, reduces noise and vibration caused by air turbulence, and improves the running quietness and stability of the equipment.

[0101] In some embodiments of the present application, the air outlet 332 is provided with a plurality of air outlets 332, which are circumferentially spaced apart on the side of the air inlet 331.

[0102] The circumferentially spaced air outlets 332 ensure that hot air can be uniformly blown from multiple directions to the inner container cavity 101, which helps to achieve more uniform hot air distribution and ensure that food is evenly heated during cooking, avoiding local overheating or undercooked conditions.

[0103] In some embodiments, the air outlet 332 is provided with four air outlets 332, which are respectively arranged at the four corner portions of the air guide cover 33.

[0104] In some embodiments of the present application, the inner container back plate 13 is provided with an air guide groove 131, which extends in the direction from the air inlet 331 to the air outlet 332.

[0105] In this way, the design of the air guide groove 131 provides a clear path for the flow of air in the air guide cavity 301, guiding air to flow from the air inlet 331 to the air outlet 332. By optimizing the flow path, air flow resistance is reduced and air circulation efficiency is improved. At the same time, through the guidance of the air guide groove 131, air can better contact the heating element 31 during flow, thereby improving the heat transfer efficiency. Efficient hot air flow and heating system reduce the ineffective loss of heat and improve energy utilization. The design of the air guide groove 131 helps to smooth air flow, reduces noise and vibration caused by air turbulence, and improves the running quietness and stability of the equipment.

[0106] The steam oven 100 provided in the application comprises a box body 10, a door body 20 and a heating fan 30. The box body 10 is internally formed with an inner cavity 101, and the box body 10 is provided with an opening communicating with the inner cavity 101. The door body 20 is rotatably arranged on the box body 10, and the door body 20 is used for closing the opening. The heating fan 30 is arranged on the bottom wall of the inner cavity 101 on the side away from the opening. The door body 20 is provided with an arc-shaped glass 21. When the door body 20 closes the opening of the inner cavity 101, the arc-shaped glass 21 is opposite to the bottom wall of the inner cavity 101. From the center to the edge of the arc-shaped glass 21, the distance between the arc-shaped glass 21 and the bottom wall in the depth direction of the inner cavity 101 gradually decreases. The heating fan 30 is configured to suck air in the central region of the inner cavity 101 to heat to generate hot air along the depth direction of the inner cavity 101. The generated hot air is transmitted to the opening of the inner cavity 101 along the periphery of the inner cavity 101 after passing through the bottom wall. The arc-shaped glass 21 is configured to reflect and guide the hot air blown from the periphery of the inner cavity 101 to the central region of the inner cavity 101.

[0107] In this way, by designing the arc-shaped glass 21 on the door body 20 and making the arc-shaped glass 21 opposite to the bottom wall of the inner cavity 101, the arc-shaped glass 21 can effectively reflect heat, can gather hot air in the required direction, can reflect and guide the hot air blown from the periphery of the inner cavity 101 to the central region of the inner cavity 101, can make the temperature of the central region of the inner cavity 101 significantly rise, can make the heat emitted by the heating fan 30 concentratedly transmitted to food, and can achieve ideal heating effect. In the case of designing the temperature at 230℃, the central temperature of the inner cavity 101 can reach the effect of high-temperature baking of a traditional oven, so that the food can be quickly baked, and the cooking efficiency and effect are improved. Meanwhile, by reflecting heat by the arc-shaped glass 21, the heat transmitted to the glass can be effectively reduced, the temperature rise of the door body 20 is reduced, the customer experience is improved, and the energy consumption of the whole machine is reduced.
