[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Reference Figures 1 to 3The flat-structured integrated range hood and stove unit of this utility model includes a base 100, a stove 200, and a fan assembly 300. The base 100 has a table 110 on its upper end and an air duct cavity 120. The base 100 has an air inlet 130 on the table 110, which is connected to the air duct cavity 120. The base 100 has an air outlet 140 on one side along the horizontal direction, which is connected to the air duct cavity 120. The stove 200 is set inside the base 100. The fan assembly 300 is set inside the base 100 and located in the air duct cavity 120. The fan assembly 300 includes a centrifugal impeller 310 and an impeller driver 320. The rotation axis of the centrifugal impeller 310 is set along the vertical direction. The air inlet 130 is located on one side of the centrifugal impeller 310 along the rotation axis, and the air outlet 140 is located on one side of the centrifugal impeller 310 along the radial direction. The axial dimension of the centrifugal impeller 310 is smaller than the diameter of the centrifugal impeller 310.

[0032] By placing the cooktop 200 inside the base 100 to reduce the vertical dimensions of the integrated range hood and cooktop unit, and by using a centrifugal impeller 310 in the fan assembly 300, with the rotation axis of the centrifugal impeller 310 set along the vertical direction and the axial dimension of the centrifugal impeller 310 being smaller than its diameter, the vertical dimensions of the centrifugal impeller 310 are reduced, thus reducing the vertical dimensions of the fan assembly 300. This results in a flatter integrated range hood and cooktop unit, reducing the space requirements for cabinet installation.

[0033] In this embodiment, a filter plate 400 is also included. The air duct cavity 120 includes an air inlet 121 and a fan cavity 122. The air inlet 121 is arranged vertically, with an air inlet 130 located at the upper end of the air inlet 121. The lower end of the air inlet 121 extends to the upper wall of the fan cavity 122. The filter plate 400 is arranged horizontally on the base 100 and located within the air inlet 121. The fan assembly 300 is located within the fan cavity 122. The filter plate 400 has a plate-like structure and is arranged horizontally. Compared to the solution of tilting the filter plate 400 to increase the filtration area, this solution allows the vertical dimensions of the air inlet 121 to be smaller without causing interference between the filter and the centrifugal impeller 310. This helps to reduce the vertical dimensions of the integrated range hood and cooktop, making the integrated range hood and cooktop flatter.

[0034] In this embodiment, the vertical dimension of the fan cavity 122 is A, and the horizontal dimension of the fan cavity 122 is B, satisfying A≤B. Making the vertical dimension of the fan cavity 122 smaller than its horizontal dimension allows for the adaptation of the centrifugal impeller 310, whose axial dimension is smaller than its diameter. This results in better airflow formation within the duct cavity 120 by the centrifugal impeller 310, and further reduces the vertical dimension of the base 100, thus further reducing the vertical dimension of the integrated range hood and cooktop unit, making the integrated range hood and cooktop unit flatter.

[0035] Specifically, the vertical dimension A of the fan cavity 122 is ≤ 1 / 3B, which makes the airflow effect better when using the centrifugal impeller 310, and also makes the vertical dimension of the integrated range hood and stove relatively suitable.

[0036] In this embodiment, the stove 200 is an induction cooker. The base 100 is provided with a cooker housing cavity 150, which is located on one side of the air inlet 121 along the horizontal direction. The stove 200 is located inside the cooker housing cavity 150. The vertical dimension of the air inlet 121 is C, and the vertical dimension of the cooker housing cavity 150 is D, satisfying C≥D. By making the vertical dimension of the air inlet 121 no smaller than the vertical dimension of the cooker housing cavity 150, the vertical dimension of the cooker housing cavity 150 can be made smaller. Furthermore, when the stove is located on one side of the air inlet 130 along the horizontal direction, the space of the base 100 is fully utilized to form an air inlet 121 with a suitable vertical dimension, making the integrated range hood and stove structure even flatter and reducing the vertical dimension of the integrated range hood and stove.

[0037] It is conceivable that in other embodiments, the stove 200 may also be a gas stove, in which case a receiving groove may be recessed in the base 100, the opening of the receiving groove is located on the table surface 110 of the base 100, and the gas stove is housed in the receiving groove.

[0038] Specifically, the lower cavity wall of the stove installation chamber is provided with through holes to improve the heat dissipation effect of the stove 200.

[0039] In this embodiment, a switch cover 500 is also included. The switch cover 500 is movably disposed on the base 100 and can open or close the air inlet 130. By providing the switch cover 500, when the air duct cavity 120 and the fan assembly 300 are not in use, the switch cover 500 can be moved to the position of closing the air inlet 130 to prevent external debris or liquids from accidentally falling into the air duct cavity 120 through the air inlet 130, affecting the normal use of the fan assembly 300 and the air duct cavity 120, and reducing the impact of dust on the air duct cavity 120. When the fan assembly 300 needs to be used, the switch cover 500 is moved to the position of opening the air inlet 130, so that the fan assembly 300 can form an airflow in the air duct cavity 120 to draw in cooking fumes from the air inlet 130.

[0040] In this embodiment, the switch cover 500 is rotatably mounted on the base 100 and located within the air inlet 121. The filter plate 400 is located at the lower end of the air inlet 121, and the switch cover 500 is located above the filter plate 400. By rotatably connecting the switch cover 500 to the base 100, the switch cover 500 can open or close the air inlet 130. This structure is simple and easy to implement. Furthermore, positioning the filter plate 400 at the lower end of the air inlet 121 provides sufficient installation space for the switch cover 500 to rotate. This ensures that even when the switch cover 500 and the filter plate 400 are in a relatively compact position, the rotation of the switch cover 500 is unimpeded.

[0041] Specifically, a damping structure is provided between the switch cover 500 and the base 100, requiring a certain external force for the switch cover 500 to rotate relative to the base 100, thus avoiding the risk of the switch cover 500 rotating arbitrarily. Specifically, the switch cover 500 opens or closes the air inlet 130 by manual rotation. It is conceivable that in some embodiments, a rotation driver could be provided to drive the switch cover 500 to rotate, thereby achieving automated opening and closing of the switch cover 500. In this case, the rotation driver could be a structure that outputs rotational power, such as a motor.

[0042] Specifically, the switch cover 500 is detachably mounted to the base 100, and the filter plate 400 is also detachably mounted to the base 100, facilitating the disassembly and cleaning of the switch cover 500 and the filter plate 400. It is conceivable that in some other embodiments, the switch cover 500 may also be slidably connected to the base 100. In this case, the filter plate 400 can be driven to slide using a structure such as a linear motor or an electric push rod to close or open the air inlet 130.

[0043] Specifically, the cross-section of the switch cover 500 is trapezoidal, and the suction and diversion effect of the oil fumes is better when the air inlet 121 is opened.

[0044] Specifically, the filter plate 400 can be a metal filter or similar structure, used to cool the oil fumes, so that oil droplets in the airflow are separated and adhered to the filter plate 400.

[0045] In this embodiment, two stoves 200 are provided, and the air inlet 130 is located between the two stoves 200. When the air inlet 130 is located between the two stoves 200, it can effectively extract the cooking fumes when either stove 200 is in use; when both stoves 200 are in use simultaneously, the air inlet 130 can also simultaneously extract the cooking fumes generated by both stoves 200, resulting in a good overall fume extraction effect.

[0046] In this embodiment, an electrical control box 600 is also included, which is disposed on one side of the base 100 along the horizontal direction. Distributing the electrical control box 600 on one side of the base 100 along the horizontal direction ensures that its installation position does not increase the vertical dimensions of the integrated range hood and cooktop, thus facilitating a flatter structure for the integrated range hood and cooktop, making it suitable for cabinet spaces with limited installation height.

[0047] In this embodiment, the height of the base 100 is H, which satisfies H≤180mm. When the overall height of the base 100 is no greater than 180mm, the integrated range hood and cooktop can be used in flat cabinet spaces, which helps to improve the space utilization of the cabinet.

[0048] In this embodiment, the rotation axis of the centrifugal impeller 310 passes through the air inlet 130. When the centrifugal impeller 310 rotates, it can generate a direct and large suction force at the air inlet 130 to improve the oil fume extraction effect. It also makes the horizontal structure of the range hood relatively compact, which is conducive to the miniaturization design trend of the integrated range hood and stove, and improves the installation and user experience.

[0049] Specifically, the fan driver is a motor, and the motor's output shaft is directly connected to the centrifugal impeller 310. The motor is also located within the fan cavity 122. The centrifugal impeller 310 has a recessed portion, and the motor is at least partially located within this recessed portion. The fan driver uses a motor, which has a simple structure. Furthermore, with the motor inside the fan cavity 122, the centrifugal impeller 310 can simultaneously dissipate heat from the motor as it rotates, cooling the motor and reducing the risk of damage from overheating. The recessed portion of the centrifugal impeller 310 allows for a more compact structural layout of the motor and impeller, further reducing the height of the fan cavity 122 and enabling a more flattened design for the integrated range hood and cooktop. It is conceivable that in other embodiments, the fan driver could also be a structure that outputs rotational power, such as an internal combustion engine, which can be configured according to specific needs by those skilled in the art.

[0050] Specifically, the base 100 is also equipped with an activated carbon mesh at the air outlet 140 to further filter the airflow and reduce the impact of the exhaust air on the external environment.
