In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0042] Refer to the following Figure 1-Figure 5 The integrated stove 100 according to an embodiment of the present invention is described in detail. It should be noted that the integrated stove 100 may refer to a kitchen appliance that combines a stove 110 and a cooking device 120. It can meet the diverse cooking needs of the kitchen and is convenient and practical. The cooking device 120 here may be an oven, a microwave oven, a steam-bake all-in-one machine, etc. The integrated stove 100 has various functions. The gas stove 110 can be used for fire adjustment and cooking methods such as frying and soup making, and the electric oven can be used for oven cooking methods such as baking and barbecue. Through the integrated control panel, the user can easily select different function modes and temperatures, and set parameters such as timing. The integrated stove 100 combines the gas stove 110 and the electric oven in one, and usually includes a gas stovetop, a stove, a control panel and an electric oven. Through the integrated design, the cumbersome steps of installing and connecting the gas stove 110 and the independent oven can be omitted, and the kitchen space can be made neater.

[0043] like Figure 1 As shown, the integrated stove 100 according to the embodiment of the present invention includes: a stove 110, a cooking device 120 and an air duct assembly 130. It should be noted that the stove 110 generates heat during operation, and when the heat is transferred to the cooking device 120, it will have an adverse effect on the cooking device 120. For example, due to the high temperature of the environment where the cooking device 120 is located, it is difficult for the cooking device 120 to dissipate heat, which in turn causes the cooking device 120 to fail to cook.

[0044] Specifically, the air duct assembly 130 is located between the stove 110 and the cooking device 120, and is used to dissipate heat for the stove 110 and the cooking device 120. Specifically, the air duct assembly 130 can cool the electric control box, the bottom of the stove 110, and the door 121 of the cooking device 120. Here, it needs to be explained that the components of the air duct assembly 130 are combined in a certain way to form a closed air duct cavity 134, and the air flow can flow in the air duct cavity 134. During the flow of the air flow, the heat generated by the stove 110 or the heat generated by the cooking device 120 will be taken away, so as to achieve the purpose of heat dissipation. In order to improve the heat dissipation effect of the air duct assembly 130, the air duct assembly 130 can be made of a material with a high thermal conductivity, such as a metal plate. The air duct assembly 130 can be a component of various shapes, such as a straight pipe, an elbow, a branch pipe, etc. These components are connected by connectors and sealing materials to ensure the integrity and air tightness of the air duct cavity 134.

[0045] The design of the air duct cavity 134 needs to consider the transmission characteristics of the airflow therein, including air volume, wind speed, pressure loss, etc. The shape of the air duct cavity 134 will directly affect the flow state of the airflow. Based on this, in the embodiment of the present invention, the inner wall of the air duct cavity 134 has an inclined guide wall surface 131, and the inclined guide wall surface 131 has a guiding effect on the airflow. The inclined guide wall surface 131 can guide the airflow to turn smoothly, replacing the vertical edge at the position where the air duct turns or the cross-sectional area of ​​the air duct cavity 134 changes, so that the airflow can smoothly transition in the air duct cavity 134, thereby reducing the resistance of the straight edge in the air duct cavity 134 to the airflow, and achieving a better cooling effect.

[0046] According to the integrated stove 100 of the embodiment of the present invention, an inclined guide wall 131 is provided on the inner wall of the air duct cavity 134. The inclined guide wall 131 has a guiding effect on the airflow. The inclined guide wall 131 can guide the airflow to turn smoothly, replacing the vertical edge at the position where the air duct turns or the cross-sectional area of ​​the air duct cavity 134 changes, so that the airflow can smoothly transition in the air duct cavity 134, thereby reducing the resistance of the straight edge in the air duct cavity 134 to the airflow, thereby achieving a better cooling effect.

[0047] According to some embodiments of the present invention, see Figure 2 and Figure 3As shown, there are multiple inclined guide walls 131, and the multiple inclined guide walls 131 are spaced apart along the direction of airflow. Thus, by setting up multiple inclined guide walls 131, the airflow can be guided to flow smoothly along the predetermined air duct, reducing the resistance of the inner wall of the air duct cavity 134 to the airflow, thereby achieving a better cooling effect. It should be noted that multiple of the multiple inclined guide walls 131 can be spaced apart along the direction of airflow; of course, the arrangement of the multiple inclined guide walls 131 is not limited to this. For example, in some examples, with the direction of airflow as the axis, the multiple inclined guide walls 131 can also be spaced apart along the circumferential direction surrounding the axis.

[0048] According to some embodiments of the present invention, see Figure 2 and Figure 3 As shown, the air duct cavity 134 includes a main flow section 135 and a guide section 136. Here, the main flow section 135 can provide a flow space for the airflow, that is, the airflow can flow in the main flow section 135. In some examples, the main flow section 135 can extend in the front-to-back direction. In order to enable the air duct assembly 130 to effectively dissipate heat for the cooking device 120, according to some embodiments of the present invention, such as Figure 3 As shown, the wall surface of the main flow section 135 is constructed on the air duct assembly 130, and the wall surface of the main flow section 135 is in contact with the top wall of the cooking device 120. In addition, by making the air duct assembly 130 and the cooking device 120 in contact, the compactness of the structure can be improved. Furthermore, the side wall of the main flow section 135 close to the stove 110 is in contact with the bottom wall of the stove 110.

[0049] Furthermore, if Figure 3 As shown, the main flow section 135 is connected to the guide section 136. In the guide section 136, the air duct assembly 130 includes a first side wall 132 and a second side wall 133 that are arranged opposite to each other, and the first side wall 132 and the second side wall 133 are parallel to each other. It should be noted that the design that the first side wall 132 and the second side wall 133 are parallel to each other can make the first side wall 132 and the second side wall 133 construct a parallel air duct structure, thereby reducing the number of expansion sections, ensuring the flow speed of the airflow, and improving the cooling effect.

[0050] Furthermore, at least one of the first side wall 132 and the second side wall 133 forms an inclined guide wall surface 131. It should be noted that the first side wall 132 and the second side wall 133 form an air duct structure with parallel oblique edges, so that the inclined structure can be used to guide the airflow and change the airflow direction, replacing the method of changing the airflow speed by using an expanded cross section, thereby ensuring the airflow speed and achieving a better cooling effect.

[0051] According to some embodiments of the present invention, see Figure 2 and Figure 3As shown, the cooker 110 is located on the side of the first side wall 132 away from the air duct cavity 134, and the cooking device 120 is located on the side of the second side wall 133 away from the air duct cavity 134. In this way, the structure of the first side wall 132 can be adapted to the shape of the cooker 110, and the structure of the second side wall 133 can be adapted to the shape of the cooking device 120.

[0052] According to some embodiments of the present invention, see Figure 3 As shown, in the direction of airflow, the guide section 136 is inclined toward the stove 110, so that the airflow can be arranged around the stove 110, thereby intensively dissipating heat for the stove 110. Further, in the direction of airflow, the guide section 136 is located downstream of the main section 135. It should be noted that the guide section 136 can change the direction of airflow, so that the heat dissipation airflow surrounds the stove 110 or the cooking device 120, thereby improving the heat dissipation of the integrated stove 100.

[0053] In some embodiments, see Figure 3 As shown, the cross-sectional area of ​​the main flow section 135 is equal to the cross-sectional area of ​​the guide section 136. This can replace the method of using the expanded cross section to change the air flow velocity, ensure the air flow velocity, and achieve a better cooling effect.

[0054] According to some embodiments of the present invention, Figure 4 and Figure 5 As shown, the integrated stove 100 also includes a branch air duct 140, one end of which is connected and communicated with the air duct assembly 130, and the other end is arranged at the door control switch 141. The airflow in the air duct assembly 130 can enter the branch air duct 140, so that the airflow in the air duct assembly 130 can be used to dissipate heat and cool the door control switch 141. Figure 2 As shown, according to some embodiments of the present invention, the cross-sectional area of ​​the branch air duct 140 is smaller than the cross-sectional area of ​​the air duct assembly 130 , thereby ensuring the heat dissipation effect of the air duct assembly 130 while diverting the air duct assembly 130 .

[0055] Combination Figure 5 As shown, in some embodiments, the branch air duct 140 may be constructed of a metal sheet, which may be fixedly connected to the air duct assembly 130 by means of screws or the like. Here, the specific structure of the branch air duct 140 is not limited. For example, in some examples, the cross-section of the branch air duct 140 may be a square.

[0056] According to some embodiments of the present invention, Figure 4 and Figure 5As shown, the air inlet end of the air duct assembly 130 is located at the rear side of the cooking device 120, and the air outlet end of the air duct assembly 130 is arranged at the door body 121 of the cooking device 120. In this way, the air duct assembly 130 can surround the periphery of the cooking assembly, thereby improving the heat dissipation effect of the air duct assembly 130 on the cooking device 120.

[0057] According to some embodiments of the present invention, Figure 5 As shown, the integrated stove 100 further includes a crossflow fan 150, which is used to drive the airflow in the air duct assembly 130, and the crossflow fan 150 is connected to the housing of the cooking device 120. The crossflow fan 150 is a ventilation device, which makes the air flow continuously along the axial direction through the rotating impeller, thereby generating a large amount of airflow. Due to the characteristics of its working principle, the crossflow fan 150 can provide a higher wind speed and a larger air volume, thereby taking advantage of the good airflow driving effect of the crossflow fan 150 to accelerate the airflow in the air duct assembly 130, thereby improving the heat dissipation effect of the air duct assembly 130.

[0058] In order to optimize the structure of the integrated stove 100, in some embodiments, see Figure 2 and Figure 3 As shown, the stove 110 is located above the cooking device 120, the air duct assembly 130 is attached to the top of the cooking device 120, and the air flow in the air duct assembly 130 is from the rear side of the cooking device 120 to the front side of the cooking device 120, and the cross-flow fan 150 is arranged on the rear side of the cooking device 120; the cooking device 120 is a structure with a front door, that is, the door body 121 is arranged on the front side of the cooking device, and the air flow in the air duct assembly 130 can be blown to the door body 121 on the front side, so that the door body 121 can be cooled; in addition, the electric control box of the cooking device 120 is arranged at the door body 121, and the air flow in the air duct assembly 130 can also cool the electric control box.

[0059] Refer to the following Figure 1-Figure 5 The air duct assembly 130 according to the embodiment of the present invention is described in detail. It is worth noting that the following description is only for exemplary purposes and is not a specific limitation of the present invention.

[0060] like Figure 2 and Figure 3 As shown, the air duct assembly 130 has an air duct cavity 134, and the inner wall of the air duct cavity 134 is provided with an inclined guide wall surface 131. The inclined guide wall surface 131 has a guiding effect on the airflow, and the inclined guide wall surface 131 can guide the airflow to turn smoothly, replacing the vertical edge at the position where the air duct turns or the cross-sectional area of ​​the air duct cavity 134 changes, so that the airflow can smoothly transition in the air duct cavity 134, thereby reducing the resistance of the straight edge in the air duct cavity 134 to the airflow, and achieving a better cooling effect.

[0061] See also Figure 3 As shown, the air duct cavity 134 includes a main flow section 135 and a guide section 136. The main flow section 135 is connected to the guide section 136. The main flow section 135 can provide a space for the air flow to flow, and the guide section 136 can be used to guide the air flow to turn. The cross-sectional area of ​​the main flow section 135 is equal to the cross-sectional area of ​​the guide section 136. In this way, the number of expansion cross sections can be reduced, and the flow speed of the air flow can be guaranteed.

[0062] In the guide section 136, the air duct assembly 130 includes a first side wall 132 and a second side wall 133 that are arranged opposite to each other. The first side wall 132 and the second side wall 133 are parallel to each other, thereby reducing the number of expansion cross sections, ensuring the flow speed of the airflow, and improving the cooling effect. At least one of the first side wall 132 and the second side wall 133 is constructed with an inclined guide wall surface 131, so that the inclined structure can be used to guide the airflow and change the flow direction of the airflow, replacing the method of changing the flow speed of the airflow by using the expanded cross section, ensuring the flow speed of the airflow, and having a better cooling effect.

[0063] Refer to the following Figure 1-Figure 5 The integrated stove 100 according to the embodiment of the present invention is described in detail. It is worth noting that the following description is only for exemplary purposes and is not a specific limitation of the present invention.

[0064] like Figure 1 As shown, the integrated stove 100 includes a stove 110, a cooking device 120 and an air duct assembly 130. The stove 110 is located above the air duct assembly 130. It should be noted that the stove 110 can provide an open flame for the pot. In order to prevent the heat generated by the open flame from affecting the cooking device 120, the air duct assembly 130 can be arranged between the stove 110 and the cooking device 120 to dissipate heat for the stove 110 and the cooking device 120; of course, the cooking device 120 will also generate heat during operation, and the air duct assembly 130 can also take away the heat generated by the cooking device 120, thereby playing a role in heat dissipation, thereby preventing the cooking device 120 from being in a high temperature environment.

[0065] Furthermore, if Figure 2 As shown, the air inlet end of the air duct assembly 130 may be provided with a crossflow fan 150, which can drive the airflow to flow in the air duct assembly 130; the air outlet end of the air duct assembly 130 may be provided at the door body 121 of the cooking device 120, so that the air duct assembly 130 can also dissipate heat for the door body 121 of the cooking device 120 and the control device of the cooking device 120. The airflow channel defined by the air duct assembly 130 surrounds the top of the cooking device 120, so that the heat dissipation effect of the air duct assembly 130 can be improved.

[0066] See also Figure 3As shown, the inner wall of the air duct cavity 134 is provided with an inclined guide wall surface 131. The inclined guide wall surface 131 has a guiding effect on the airflow, and the inclined guide wall surface 131 can guide the airflow to turn smoothly, replacing the vertical edge at the position where the air duct turns or the cross-sectional area of ​​the air duct cavity 134 changes, so that the airflow can smoothly transition in the air duct cavity 134, thereby reducing the resistance of the straight edge in the air duct cavity 134 to the airflow, and achieving a better cooling effect.

[0067] In addition, see Figure 4 and Figure 5 As shown, the integrated stove 100 also includes a branch air duct 140, one end of the branch air duct 140 is connected to the air duct cavity 134 of the air duct assembly 130, and the other end is arranged at the door-controlled switch 141. In this way, the branch air duct 140 can dissipate heat for the door-controlled switch 141, so that the door-controlled switch 141 can be placed in an environment with moderate temperature, which can effectively delay the aging of the door-controlled switch 141 and further extend the service life of the door-controlled switch 141.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
