Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more particularly to a cooking appliance. Background Technology

[0002] Steam ovens or steam-grill combos typically include a cooling fan, which is used to dissipate heat during cooking to ensure the proper functioning of the appliance.

[0003] After cooking, a large amount of high-temperature steam remains in the cooking cavity of cooking appliances. When the user opens the door, the steam will rush out and hit them directly, easily causing burns. Generally, exhaust fans are incorporated into such cooking appliances to expel the high-temperature steam from inside the cooking cavity before the user opens the door. In related technologies, a cooling fan operates when heat dissipation is needed during cooking; an exhaust fan operates when high-temperature steam needs to be expelled after cooking.

[0004] However, cooking appliances using this technology have a large number of fans, resulting in higher costs. Utility Model Content

[0005] An embodiment of this application provides a cooking appliance, which includes a housing, a steam exhaust assembly, and an air inlet assembly. The housing has a cooking cavity, and the steam exhaust assembly and the air inlet assembly are both disposed on the housing. The steam exhaust assembly includes a steam exhaust fan, a duct housing, and a steam exhaust pipe. The duct housing forms a steam exhaust duct, the steam exhaust fan is configured to blow airflow upstream of the steam exhaust duct, the downstream of the steam exhaust duct communicates with the outside of the housing, and the steam exhaust pipe connects the cooking cavity and the downstream of the steam exhaust duct.

[0006] The air intake assembly has an air intake channel that connects the exhaust duct and the cooking chamber. The airflow blown out by the exhaust fan is diverted to the air intake channel and enters the cooking chamber so that the cooking chamber can discharge steam through the exhaust pipe.

[0007] In some embodiments, the air inlet channel has an air inlet interface; the air inlet interface is located inside the exhaust duct and faces the exhaust fan's outlet side.

[0008] In some embodiments, the housing has a vent, the vent duct is connected to the vent, and the vent fan is located at the end of the vent duct away from the vent; the air inlet channel has an air inlet interface connected to the vent duct, and the air inlet interface is located at the end of the vent duct near the vent fan.

[0009] In some embodiments, the air intake assembly includes an air intake housing and an air intake pipe. At least a portion of the air intake housing is located within the exhaust duct. The structure of the air intake housing located within the exhaust duct has an air intake interface, which is connected to the exhaust duct. A first end of the air intake pipe is connected to the air intake housing, and a second end of the air intake pipe is connected to the side wall of the cooking cavity to form the air intake channel.

[0010] In some embodiments, the air intake assembly further includes an air intake valve connected to the air intake duct and configured to control the opening and closing of the air intake duct.

The duct top cover is connected to the duct bottom plate and surrounds the exhaust duct to form the exhaust duct. The exhaust fan is connected to the duct bottom plate. The duct bottom plate has an opening, and the air inlet housing is opposite to the opening and passes through the opening.

[0012] In some embodiments, the air duct cover is located on the side of the air duct base plate away from the cooking cavity; the air duct base plate has a gap with the outer wall of the cooking cavity; a portion of the air inlet housing is located in the gap; and one end of the air inlet pipe connected to the air inlet housing is disposed in the gap.

[0016] This application provides a cooking appliance, including an exhaust assembly and an air inlet assembly. The exhaust assembly includes an exhaust fan configured to blow airflow into the exhaust duct. When the cooking cavity exhausts steam, the airflow blown by the exhaust fan is diverted to the air inlet duct. This application enables the airflow in the exhaust duct to be diverted, thus facilitating both heat dissipation during cooking and the removal of high-temperature steam after cooking with a single exhaust fan. This dual-purpose fan reduces the number of fans required and saves on the cost of the cooking appliance.

[0033] After a steam oven or steam-grill combination appliance finishes its steaming function, a large amount of high-temperature steam remains inside the cooking cavity. If the user opens the door, the steam can rush out and cause burns. Therefore, a forced exhaust structure is introduced into these appliances to expel the steam from the cooking cavity before the user opens the door. Currently, there are two main exhaust methods. The first involves opening a hole in the cavity; by adjusting the size of the opening, less steam is expelled during steaming, and the exhaust process is rapid. This process requires the steam to diffuse naturally, resulting in a relatively slow overall speed. The second method uses a blower to force air into the cavity, compressing the steam and achieving rapid exhaust. This method requires attention to issues such as the sealing of the valve body.

[0034] In related technologies, to ensure the normal operation of cooking appliances, steam ovens or steam-grill combination appliances generally include cooling fans, which are used to dissipate heat during the cooking process. Therefore, the cooling fan operates when heat dissipation is needed during cooking; and the exhaust fan operates when high-temperature steam needs to be expelled after cooking. However, these technologies involve a large number of fans, resulting in higher costs for the cooking appliances.

[0035] To address the aforementioned technical problems, this application provides a cooking appliance including an exhaust assembly and an air inlet assembly. The exhaust assembly includes an exhaust fan configured to blow airflow into the exhaust duct. When the cooking cavity is venting steam, the airflow blown by the exhaust fan is diverted to the air inlet duct. This application enables the airflow in the exhaust duct to be diverted, thus facilitating both heat dissipation during cooking and the removal of high-temperature steam after cooking with a single exhaust fan. This achieves a dual function for the fan, reducing the number of fans required and saving on the cost of the cooking appliance.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] Reference Figure 1 and Figure 2 As shown, this application provides a cooking appliance 100, which includes a box and a shell, the box being housed in the shell, and the box having a cooking cavity 110.

[0038] In this embodiment, the type of cooking appliance 100 is not limited. For example, the cooking appliance 100 in this embodiment can be an oven, a steam oven, a steam oven combination appliance, or a steam oven-microwave combination appliance, etc. In this embodiment, a steam oven combination appliance is mainly used as an example for description.

[0039] A steam oven is an all-in-one appliance that combines the functions of a gas stove, steamer, and oven. Because one appliance can function as multiple independent kitchen appliances, it allows for simultaneous stir-frying / stewing on the top and steaming / baking on the bottom, freeing up kitchen space. Its principle is to use the appliance's heating system to heat water into steam, which is then used to steam, bake, or cook food.

[0040] It should be noted that in this embodiment, the housing is the inner pot of the cooking appliance 100, and the cooking cavity 110 is formed within the inner pot. The inner pot is one of the core components of the steam oven, and it is used for cooking food. The material of the inner pot is not limited. For example, the inner pot can be made of stainless steel, which can withstand high temperatures of water and detergents, and also has antibacterial properties and is easy to clean; alternatively, the inner pot can be made of plastic, which has certain impact resistance and electrical insulation properties; or, the inner pot can be made of ceramic, which has the advantages of being smooth, slow-deteriorating, and corrosion-resistant, and can also improve the washing effect. This embodiment does not limit this aspect.

[0041] The top of the inner pot typically houses electrical components such as heating elements, water pumps, and circuit boards. During cooking, the inner pot generates heat, potentially causing these components to overheat. Therefore, to ensure the proper functioning of the electrical components and the cooking appliance 100, and to prevent damage to the electrical components, this embodiment refers to... Figure 1 and Figure 2 As shown, the cooking appliance 100 may include a steam exhaust assembly 120, which may be mounted on the housing.

[0042] In the embodiments of this application, reference is made to Figures 1 to 3 As shown, the exhaust assembly 120 may include an exhaust fan 121, a duct housing 122, and an exhaust pipe 123. The duct housing 122 encloses an exhaust duct 124. The exhaust pipe 123 connects the cooking cavity 110 and the exhaust duct 124. The downstream of the exhaust duct 124 is connected to the outside of the housing. The exhaust fan 121 is configured to blow airflow into the upstream of the exhaust duct 124. The airflow flows from the upstream to the downstream of the exhaust duct 124.

[0043] It should be noted that the exhaust fan 121 here is a cooling fan in the existing structure.

[0044] The heat dissipation path of the exhaust fan 121 is as follows: During the cooking process, steam generated in the steam generating pipe enters the cooking cavity 110 to heat the food. Excess steam enters the exhaust duct 124 through the exhaust pipe 123. The exhaust fan 121 blows airflow into the exhaust duct 124, expelling the steam from the exhaust duct 124 to the outside of the cooking appliance 100. Additionally, the exhaust fan 121 can expel heat from the top of the inner pot through the exhaust duct 124. This effectively dissipates heat from the electrical components, keeping them within a stable temperature range, ensuring the normal operation of the electrical components and the cooking appliance 100, and preventing damage to the electrical components.

[0045] For example, the heat dissipation path of the exhaust fan 121 can be referred to Figure 4 and Figure 5 The direction of arrow 'a' is indicated in the diagram.

[0046] In order to reduce the cost of cooking appliance 100 and further achieve the function of venting high-temperature steam after cooking, in this embodiment of the application, reference is made to... Figure 1 and Figure 2 As shown, in addition to the structure of the cooking appliance 100 itself, the cooking appliance 100 also includes an air intake component 130, which can be installed on the housing.

[0047] The air intake assembly 130 has an air intake channel 135, which connects the exhaust duct 124 and the cooking cavity 110, so that when the cooking cavity 110 exhausts steam, the airflow blown by the exhaust fan 121 is diverted to the air intake channel 135.

[0048] The exhaust path of the exhaust fan 121 is as follows: After cooking is finished, part of the airflow blown by the exhaust fan 121 is diverted to the air inlet channel 135 and enters the cooking cavity 110 through the air inlet channel 135. The high-temperature steam inside the cooking cavity 110 is squeezed into the exhaust pipe 123 and then enters the exhaust duct 124 through the exhaust pipe 123. The exhaust fan 121 discharges the high-temperature steam in the exhaust duct 124 to the outside of the cooking appliance 100.

[0049] For example, the exhaust path of exhaust fan 121 can be referred to Figure 4 and Figure 5 The direction of arrow b in the diagram is indicated.

[0050] It is understood that in this embodiment, the heat dissipation of the exhaust fan 121 is carried out during the cooking process, and the exhaust of the exhaust fan 121 is carried out after the cooking is completed.

[0051] In this embodiment, the specific locations of the exhaust assembly 120 and the air inlet assembly 130 are not limited. For example, the exhaust assembly 120 and the air inlet assembly 130 can be located on the outside of the enclosure. This arrangement, on the one hand, ensures the cleanliness of the interior of the enclosure, reduces the complexity of the internal structure, and makes cleaning easier; on the other hand, it facilitates the effective utilization of steam and the heat dissipation of the equipment; furthermore, by placing both the exhaust assembly 120 and the air inlet assembly 130 on the outside of the enclosure, the heat exchange process can be better controlled, which not only reduces energy consumption but also helps to lower operating costs.

[0052] Therefore, in this embodiment, the airflow from the exhaust duct 124 can be diverted, thus requiring only one fan. This fan is a conventional cooling fan, and in this application, it can also function as the exhaust fan 121. In addition to using a cooling fan to expel excess high-temperature steam from the cooking cavity 110 into the exhaust duct 124 during the cooking process, a portion of the airflow is diverted to expel the high-temperature steam remaining in the cooking cavity 110 after cooking. Therefore, this application achieves both heat dissipation during cooking and the expulsion of high-temperature steam after cooking, realizing a dual-purpose fan, which helps reduce the number of fans and saves on the cost of the cooking appliance 100.

[0053] In one feasible implementation, refer to Figure 4 and Figure 5 As shown, the air inlet channel 135 may have an air inlet interface 133; the air inlet interface 133 is located inside the exhaust air duct 124 and faces the air outlet side of the exhaust fan 121.

[0054] In this embodiment, the shape of the air inlet 133 is not limited and can be set according to the specific design and actual needs of the exhaust fan 121 and the exhaust duct 124. For example, the shape of the air inlet 133 can be circular or square. This embodiment does not limit this. In addition, the size of the air inlet 133 is not limited.

[0055] In this embodiment, the air inlet 133 is located inside the exhaust duct 124. This helps to ensure that a portion of the airflow blown out by the exhaust fan 121 can be diverted to the air inlet duct 135, thereby maximizing the utilization rate of the airflow.

[0056] In this embodiment, the air inlet 133 is positioned facing the exhaust fan 121. This has several advantages: firstly, it utilizes the airflow already generated by the exhaust fan 121 to drive the air intake, reducing the energy required to drive the air intake independently; secondly, it ensures smooth airflow, avoids dead zones, and improves the uniformity and efficiency of the air intake; and thirdly, it simplifies the design of the air intake system, reducing system complexity and maintenance costs.

[0057] In one feasible implementation, refer to Figure 4 As shown, the housing has an exhaust port 141, an exhaust duct 124 connected to the exhaust port 141, and an exhaust fan 121 located at the end of the exhaust duct 124 away from the exhaust port 141; the air inlet duct 135 has an air inlet interface 133 connected to the exhaust duct 124, and the air inlet interface 133 is located at the end of the exhaust duct 124 near the exhaust fan 121.

[0058] In this embodiment, the cooking appliance 100 includes a panel 140 connected to the housing, and a steam vent 141 can be formed on the panel 140. In this way, high-temperature steam in the exhaust duct 124 is discharged to the outside of the cooking appliance 100 through the steam vent 141, helping to ensure that the steam and heat generated during cooking can be quickly discharged, preventing the internal temperature of the cooking appliance 100 from becoming too high. Furthermore, the location of the steam vent 141 on the panel 140 facilitates regular cleaning and maintenance by the user, reducing grease buildup and maintaining the cleanliness and hygiene of the cooking appliance 100.

[0059] In this embodiment, the exhaust fan 121 is located at the end of the exhaust duct 124 away from the exhaust port 141. This helps to optimize and extend the airflow path of the exhaust duct 124, thereby improving the exhaust efficiency and exhaust effect of the exhaust fan 121.

[0060] In one feasible implementation, refer to Figure 4 As shown, the air intake assembly 130 may include an air intake housing 131 and an air intake pipe 132. At least a portion of the air intake housing 131 is located within the exhaust duct 124. The structure of the air intake housing 131 located inside the exhaust duct 124 has an air intake interface 133, which is connected to the exhaust duct 124. The first end of the air intake pipe 132 is connected to the air intake housing 131, and the second end of the air intake pipe 132 is connected to the side wall of the cooking cavity 110 to form an air intake channel 135.

[0061] In this embodiment, the design of the air inlet housing 131 can constrain the airflow, guide the airflow and control the direction of airflow, and ensure that the airflow flows along a preset path, thereby improving the efficiency and effectiveness of airflow utilization.

[0062] In one feasible implementation, refer to Figure 1 , Figure 2 and Figure 4 As shown, the air intake assembly 130 may also include an air intake valve 134, which is connected to the air intake pipe 132 and is configured to control the opening and closing of the air intake pipe 132.

[0063] In this embodiment, the air inlet valve 134 is closed during heat dissipation and opened during steam exhaust. This is because, when the cooking appliance 100 is working normally, part of the airflow in the exhaust duct 124 is diverted to the air inlet port 133, but at this time, due to the function of the air inlet valve 134, it will not directly enter the cooking cavity 110; when cooking is finished and it is necessary to quickly exhaust the high-temperature steam in the cooking cavity 110, the air inlet valve 134 is opened, and air enters the air inlet port 133 under the action of the exhaust fan 121, and enters the cooking cavity 110 through the air inlet valve 134, squeezing out the steam in the cooking cavity 110 to achieve rapid steam exhaust.

[0064] In addition, this configuration ensures that even if the sealing ring of the air inlet valve 134 ages and causes a small amount of leakage after long-term use, and steam leaks into the exhaust duct 124, it will be pushed back by the airflow of the exhaust fan 121, thus ensuring that it will not affect the electrical components.

[0065] In one feasible implementation, refer to Figure 4 As shown, the duct housing 122 may include a duct top cover 1221 and a duct bottom plate 1222. The duct top cover 1221 is connected to the duct bottom plate 1222 and forms an exhaust duct 124. The exhaust fan 121 is connected to the duct bottom plate 1222. The duct bottom plate 1222 is provided with an opening 1223. The air inlet housing 131 is opposite to the opening 1223 and passes through the opening 1223.

[0066] In this embodiment, the structure of the duct cover 1221 is not limited. For example, the cross-section of the duct cover 1221 can be trapezoidal. With this design, when airflow passes over the trapezoidal cross-section, the air velocity is faster and the pressure is lower on the side closer to the wider side of the trapezoid, while the air velocity is slower and the pressure is higher on the narrower side. This pressure difference causes the airflow to move from the area of ​​higher pressure to the area of ​​lower pressure, thereby increasing the airflow speed and improving the heat dissipation effect.

[0067] In this embodiment, the structure of the duct base plate 1222 is not limited. For example, the shape of the duct base plate 1222 can be a flat plate, which facilitates the installation of the exhaust fan 121 and helps to improve the assembly stability of the exhaust fan 121.

[0068] In this embodiment of the application, the bottom plate 1222 of the air duct is provided with an opening 1223, and the air inlet housing 131 passes through the opening 1223. This design helps to ensure that a portion of the airflow blown out by the exhaust fan 121 can be diverted to the air inlet channel 135, thereby reducing the waste of airflow and improving the utilization rate of airflow.

[0069] It should be noted that in this embodiment, the height of the air inlet 133 is less than the height of the exhaust duct 124, and the width of the air inlet 133 is less than the width of the exhaust duct 124. This helps to reduce the impact on the airflow in the exhaust duct 124, thereby ensuring effective heat dissipation for the cooking appliance 100. The dimensions of the air inlet 133 and the exhaust duct 124 can be set according to the actual product.

[0070] In one feasible implementation, the air duct cover 1221 is located on the side of the air duct bottom plate 1222 opposite to the cooking cavity 110; the air duct bottom plate 1222 has a gap with the outer wall of the cooking cavity 110.

[0071] For example, in this embodiment, the gap in the height direction of the cooking appliance 100 is located between the bottom plate 1222 of the air duct and the top wall of the cooking cavity 110, and the air duct cover is located above the air inlet housing 131. In this way, the airflow entering the exhaust air duct 124 and the air inlet channel 135 respectively flows in the horizontal direction, which can ensure smooth airflow, avoid dead corners in airflow, and improve the uniformity and efficiency of air intake.

[0072] In this embodiment, a portion of the structure of the air inlet housing 131 is located within the gap; the end of the air inlet pipe 132 connected to the air inlet housing 131 is also located within the gap. This helps ensure that a portion of the airflow blown by the exhaust fan 121 can be diverted to the air inlet channel 135, reducing airflow waste and improving airflow utilization. Furthermore, this design also helps improve the space utilization of the outer wall of the cooking cavity 110.

[0073] In one feasible implementation, refer to Figure 4 and Figure 5 As shown, the air inlet housing 131 may be provided with a connecting connector 1311, and the air inlet pipe 132 is connected to the connecting connector 1311; the connecting connector 1311 and the air inlet interface 133 are located on the same side of the air inlet housing 131.

[0074] In this embodiment, the structure of the connecting connector 1311 is not limited. For example, the shape of the connecting connector 1311 can be adapted to the shape of the air inlet pipe 132. For instance, part of the outer wall of the connecting connector 1311 is embedded in the inner wall of the air inlet pipe 132. This helps to improve the connection stability between the connecting connector 1311 and the air inlet pipe 132, and also provides a high degree of sealing, reducing air leakage.

[0075] In this embodiment, a guide wall 1312 may be provided on the side of the air inlet housing 131 away from the air inlet interface 133. For example, the guide wall 1312 may be arc-shaped. This design has two advantages: firstly, the arc-shaped guide wall 1312 can change the direction and speed of airflow, thereby more effectively guiding the airflow to flow in a predetermined direction; secondly, the arc-shaped guide wall 1312 can more effectively distribute air, reduce dead zones and airflow obstruction, and improve airflow efficiency.

[0076] In one possible implementation, the exhaust pipe 123 can be connected to the end of the air duct housing 122 away from the exhaust fan 121. Exemplarily, the exhaust pipe 123 can be disposed on the side wall of the cooking cavity 110 adjacent to the air inlet pipe 132, but this embodiment is not limited to this.

[0077] The reasonable layout of the exhaust pipe 123 can ensure the smooth discharge of steam, thereby improving cooking efficiency and making the cooking process more efficient. In addition, setting the exhaust pipe 123 away from the exhaust fan 121 can reduce the amount of steam adhering to the inner pot and avoid damage to the inner pot.

[0078] In one feasible implementation, refer to Figure 1 and Figure 2 As shown, the exhaust fan 121 and the duct housing 122 are both located on the top of the housing.

[0079] This design serves several purposes. First, since electrical components such as heating elements, water pumps, and circuit boards are typically installed on the top of the enclosure, placing the exhaust fan 121 on the top maximizes heat dissipation for these components. Second, the top of the enclosure usually has ample space, facilitating the installation of larger fans and allowing for efficient airflow arrangement, ensuring both fan operation and exhaust performance. Third, the natural convection phenomenon of hot air rising and cold air sinking allows the top-mounted fan to better promote air circulation within the inner liner, accelerating the removal of heat and steam.

[0080] This application provides a cooking appliance including an exhaust assembly and an air inlet assembly. This application can divert airflow from the exhaust duct, thus requiring only one fan. This fan is a conventional cooling fan, which in this application can also function as an exhaust fan. In addition to using a cooling fan to expel excess high-temperature steam from the cooking cavity into the exhaust duct during conventional cooking, a portion of the airflow is diverted to expel the high-temperature steam remaining in the cooking cavity after cooking. Therefore, this application achieves both heat dissipation during cooking and the expulsion of high-temperature steam after cooking, realizing a dual-purpose fan, helping to reduce the number of fans and save on the cost of the cooking appliance.

[0081] It should be noted that, in the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0082] In the description of the embodiments of this application, the term "and / or" merely indicates a relationship describing the associated objects, meaning that three relationships can exist.
