Referring to fig. 1 to 3, a combined electrical appliance 1000 according to an embodiment of the present invention includes a cooking bench 100, a cooking utensil 200 and a smoke machine 300, the combined electrical appliance 1000 integrates the cooking utensil 200 and the smoke machine 300 together, and when a user uses the cooking utensil 200 to cook, the smoke machine 300 can be used to exhaust smoke generated in a cooking process to the outside, so that a smoke exhaust effect is good, and the combined electrical appliance saves space, saves energy, consumes less energy, and is environment-friendly.

The combined electrical appliance 1000 with the cooking function and the smoke discharging function can effectively reduce indoor oil smoke, avoid indoor environmental pollution, be beneficial to the health of a user and enlarge the range of the use environment of the combined electrical appliance 1000.

The cooking bench 100 is provided with a mounting hole 102. The cooktop 100 may be made of stainless steel, glass, etc. to facilitate cleaning and load bearing. In the example of fig. 1, the cooktop 100 has a rectangular shape, and in other embodiments, the cooktop may have a circular, elliptical, polygonal, or other irregular shape, without limitation.

The cooktop 200 and the range hood 300 are installed at the cooktop 100. The cookers 200 may include a gas range, an induction cooker, etc., and the cookers 200 may be embedded in the cooktop 100 or may be disposed on the upper surface of the cooktop 100.

Referring to fig. 3, the cigarette maker 300 includes a blower assembly 302, a smoke tube 304, and an air intake assembly 306. The air intake assembly 306 can be arranged in the mounting hole 102 in a lifting manner, namely, the position of the air intake assembly 306 can be adjusted. The oil smoke generated in the cooking process enters the fan assembly 302 through the air inlet assembly 306 and is discharged to the outside through the smoke pipe 304.

The fan assembly 302 is connected to the smoke tube 304 and the air intake assembly 306. For example, fan assembly 302 may include a volute 308, a motor 310, and an impeller 312, with motor 310 and impeller 312 located within volute 308. One end of the smoke tube 304 is connected to the air outlet of the volute 308, the other end of the smoke tube 304 extends to the outside, and during the operation of the fan assembly 302, the motor 310 drives the impeller 312 to rotate, so as to suck the oil smoke generated during the cooking process into the volute 308, and further the oil smoke in the volute 308 is discharged to the outside through the smoke tube 304.

In certain embodiments, the machine 300 further comprises a connecting channel 314. The air intake assembly 306 is connected to the air inlet of the volute 308 via a connecting passage 314. The intake assembly 306 includes a first position and a second position. It can be understood that when the user uses the combined electrical appliance 1000 and needs to discharge smoke, the air intake assembly 306 is in the first position, and the air intake assembly 306 can be raised above the cooking bench 100 by a certain height to achieve the effect of collecting smoke; when smoke evacuation is not required, the air intake assembly 306 is in the second position, and the air intake assembly 306 can be lowered to be in the same plane as the cooking top 100, or slightly higher or lower than the cooking top 100 to reduce the occupied space of the combined electrical appliance 1000, and improve the aesthetic property of the combined electrical appliance 1000 and the comfort of the user. With the air intake assembly 306 in the second position, the air intake assembly 306 may be at least partially received within the connecting channel 314. The elevation of the intake assembly 306 may be adjusted by manual adjustment or by a motor. Preferably, the lifting of the air intake component 306 is adjusted by a motor, which is convenient for the user to operate. In the illustrated embodiment, the connecting channel 314 is stationary. It is understood that in other embodiments, the connecting channel is also movable relative to the cooktop and/or the air intake assembly.

The air intake assembly 306 will be described in detail below.

Referring to fig. 4-6, the air intake assembly 306 includes an air intake screen structure 316 and a peripheral wall 318. The grill structure 316 includes a first intake vent 320, a grill structure 322, a first side 324, a second side 326, a third side 328, and a fourth side 330. The peripheral wall 318 includes a plurality of second intake vent sets 332, a first sidewall 334, a second sidewall 336, a third sidewall 338, and a fourth sidewall 340. A peripheral wall 318 is provided on the lower surface of the air inlet grille structure 316.

The shape of the first air inlet 320 may be square, circular, oval, polygonal or other irregular shapes, which is not limited herein. Specifically, in the example of fig. 4, the first air inlet 320 has a square shape. The first intake vent 320 will be described in further detail below by taking the square first intake vent 320 as an example. The first intake vent 320 includes two long sides 342 and two short sides 344. The long side 342 and the short side 344 are perpendicular to each other.

The grid structure 322 includes a functional grid 346 and an intensity grid 348. The grill structure 322 is disposed in the first intake vent 320. The functional grill 346 is substantially parallel to the long side 342 of the first intake vent 320 and connects the first side 324 and the second side 326. An intensity grid 348 is maintained substantially parallel to the short side 344 and connects the functional grid 346, the third side 328 and the fourth side 330. The functional grill 346 serves to secure the smoking effect of the machine 300, and the strength grill 348 serves to more stably secure the functional grill 346, increasing the strength of the grill structure 322, thereby further preventing a user from contacting the internal components of the machine 300 to avoid the risk of mechanical damage that may otherwise exist. The functional grill 346 has a rounded corner structure in the flow field front direction E, and a tangential direction Q of the rounded corner structure is directed above the cooktop 200 of the combined appliance 1000 to provide a negative pressure region.

The functional grill 346 includes a plurality of longitudinal ribs 350 in the direction of the long side 342 of the first intake vent 320, for example, in the example of fig. 6, the functional grill 346 includes 7 longitudinal ribs 350. The longitudinal rib 350 has an arc shape convex upward toward the center of the first intake port 320. The functional grill 346 has a rounded corner structure in the front end direction E of the flow field, that is, the longitudinal ribs 350 have a rounded corner structure in the front end direction E of the flow field, please refer to fig. 3, and a tangential direction Q of the rounded corner structure points to the upper side of the cooker 200 of the combined electrical appliance 1000 to provide a negative pressure area. It will be appreciated that the rounded configuration may be formed by rounding the longitudinal ribs 350 in the direction E at the front end of the flow field. Therefore, when the airflow enters the air inlet component 306 from the first air inlet 320, the airflow flowing direction of the intake air can flow from the periphery of the air inlet component 306 to the center, so that the arrangement of the negative pressure region is more deviated to be short and wide, the smoking effect of the range hood 300 with the same air volume is improved, and the generation of noise can be reduced. In addition, the flow separation in the front end direction E of the flow field can be reduced by adapting to the change of different air quantity gears and the change of the back pressure incoming flow direction D, so that the flow resistance of oil smoke flow is reduced, and the generation of local noise is reduced. It can be understood that the range hood 300 operates to form the flow field from the oil smoke, and the flow direction of the oil smoke is from the front end direction E of the flow field to the rear end direction F of the flow field.

It will be appreciated that the negative pressure zone distribution of the air intake assembly 306 affects the smoking performance of the range hood 300. Under the condition that the arrangement of the negative pressure region is more biased to be shorter and wider, the oil smoke on the peripheral side is more easily sucked into the first air inlet 320, so that the smoking effect of the range hood 300 with the same air quantity is improved. It should be noted that the longitudinal rib 350 is an arc shape protruding upward toward the center of the first air inlet 320, please refer to fig. 7, it can be understood that a tangent of one end of the longitudinal rib 350 located in the front end direction E of the flow field of the first air inlet 320 forms a first angle r with the vertical direction, a tangent of one end of the longitudinal rib 350 located in the rear end direction F of the flow field of the first air inlet 320 forms a second angle t with the vertical direction, and the first angle r is greater than the second angle t.

Referring to fig. 6, the longitudinal ribs 350 are chamfered in the rear direction F of the flow field. Therefore, the sectional area of the tail end can be reduced by chamfering the angle F in the rear end direction of the flow field, and the scale of falling vortex generated by fluid is reduced, so that the flowing resistance of oil smoke is reduced, and the generation of local noise is reduced. It can be understood that, the chamfering treatment is performed on one end of the longitudinal rib 350 in the rear end direction F of the flow field, so that the resistance of oil smoke flowing can be reduced, and the generation of local noise can be reduced. Further, the included angle m between the chamfered edge line X of the longitudinal rib 350 and the central line Y of the projection plane is not more than 45 degrees, so that the oil smoke can be ensured to flow along the edge of the longitudinal rib 350.

In a specific embodiment, the longitudinal ribs 350 have a rounded configuration at one end in the direction of the front end of the flow field E, and the longitudinal ribs 350 have a chamfered configuration at the other end in the direction of the rear end of the flow field F. Therefore, the tangential direction Q of the fillet structure points to the upper side of the cooker 200 of the combined electrical appliance 1000 to provide a negative pressure region, so that the smoke suction effect of the range hood 300 is ensured, the resistance of oil smoke flowing can be reduced, and the generation of local noise can be reduced, thereby enabling the whole combined electrical appliance 1000 to work in a better state.

The scanning line of the longitudinal rib 350 is parallel to the long side 342 of the first air inlet 320, and the projection plane of the longitudinal rib 350 is unchanged along the scanning line. Therefore, the negative pressure area is as uniform as possible along the center of the first air inlet 320, so that the smoking effect of the cooking utensils 200 at different positions is ensured, and meanwhile, the requirement of aesthetic property is met. In the illustrated embodiment, the scan lines of the longitudinal ribs 350 are all straight lines, and the projection plane of the longitudinal ribs 350 is constant along the scan lines of the longitudinal ribs 350. The distribution of the longitudinal ribs 350 in the direction of the short side 344 of the first intake vent 320 is uniform and the starting points are in the same plane. In other embodiments, the longitudinal ribs may be designed in other shapes, such as circular rings, elliptical rings, wavy strips, etc., and the plurality of longitudinal ribs may be the same shape or may include different shapes. The area and shape of its projection surface along the scan line may be variable. The distribution of the longitudinal ribs in the short side direction of the first air inlet may be non-uniform, the starting points may not be in the same plane, and there is a height difference, for example, a design method that ensures the area between every two longitudinal ribs is equal is adopted. It should be noted that the projection plane of the longitudinal rib 350 is perpendicular to the scanning line of the longitudinal rib 350.

The scanning lines of the longitudinal ribs 350 will be further described below, and it can be understood that, for one longitudinal rib 350, the upper edge of the longitudinal rib 350 can be regarded as a scanning line, and at this time, the scanning line is a straight line having a length equal to that of the longitudinal rib 350, and an arc-shaped cross section (as shown in fig. 6) can be obtained by cutting the longitudinal rib 350 along the vertical direction at any point on the scanning line, and the arc-shaped cross section is formed by translating from one end of the scanning line to the other end of the scanning line, and the arc-shaped cross section is the projection plane.

The intensity grid 348 includes a plurality of transverse ribs 352, for example, in the example of fig. 4, the intensity grid 348 includes 2 transverse ribs 352. The longitudinal ribs 350 are perpendicularly connected to the transverse ribs 352. Thus, the plurality of longitudinal ribs 350 are supportively connected by the transverse ribs 352. It is understood that the longitudinal ribs 350 are disposed along the long side 342 of the first intake vent 320, and a plurality of the longitudinal ribs 350 need to be connected together. The present embodiment ensures the stability of the grid structure 322 by providing a plurality of transverse ribs 352 such that each transverse rib 352 connects with a plurality of longitudinal ribs 350.

The transverse ribs 352 also have a rounded corner structure in the direction E of the front end of the flow field, so that noise generated at the front end of the flow field when smoke is sucked into the range hood 300 through the air inlet assembly 306 can be reduced. It will be appreciated that the fillet configuration may be formed by rounding the transverse ribs 352 in the direction E of the flow field front end. The transverse ribs 352 are chamfered obliquely in the rear end direction F of the flow field. Therefore, the sectional area of the tail end can be reduced by chamfering the angle F in the rear end direction of the flow field, and the scale of falling vortex generated by fluid is reduced, so that the flowing resistance of oil smoke is reduced, and the generation of local noise is reduced. Further, the included angle between the edge line of the chamfer angle of the transverse rib 352 and the central line of the projection plane is not more than 45 degrees, so that the oil smoke can be ensured to flow along the edge of the transverse rib 352.

In a specific embodiment, the transverse ribs 352 are rounded at one end in the direction of the front end of the flow field E, and the transverse ribs 352 are chamfered at the other end in the direction of the rear end of the flow field F. Therefore, the tangential direction Q of the fillet structure points to the upper side of the cooker 200 of the combined electrical appliance 1000 to provide a negative pressure region, so that the smoke suction effect of the range hood 300 is ensured, the resistance of oil smoke flowing can be reduced, and the generation of local noise can be reduced, thereby enabling the whole combined electrical appliance 1000 to work in a better state.

The scanning line of the transverse rib 352 is a straight line and is parallel to the short side 344 of the first air inlet 320, and the long axis of the transverse rib 352 is parallel to the air inlet axis a of the first air inlet 320. Thus, the longitudinal ribs 350 are supported by the transverse ribs 352 while satisfying aesthetic requirements. In the illustrated embodiment, the scan lines of the transverse ribs 352 are all straight lines, and the scan projection plane of the transverse ribs 352 is constant along the scan lines of the transverse ribs 352. The cross section of the transverse rib 352 along the vertical direction is substantially rectangular, and the long axis of the cross section is substantially parallel to the air inlet axis a, which refers to the central axis of the first air inlet 320. In other embodiments, the area and shape of the projection surface of the transverse rib along the scan line may be variable. It should be noted that the projection plane of the transverse rib 352 is perpendicular to the projection plane of the longitudinal rib 350. The transverse ribs 352 prevent the longitudinal ribs 350 from being deformed, thereby increasing the structural stability of the first intake vent 320.

Further, for one transverse rib 352, the upper edge of the transverse rib 352 may be regarded as a scan line, the scan line is a straight line and coincides with the radius of the projection circle of the air inlet grid 122, the transverse rib 352 is cut at any point on the scan line along the vertical direction to obtain a substantially rectangular cross section, the transverse rib 352 is formed by translating the rectangular cross section from one end of the scan line to the other end of the scan line, and the rectangular cross section is the projection plane.

Referring to fig. 4, the peripheral wall 318 is provided with a plurality of second air inlet sets 332, and each second air inlet set 332 includes a plurality of second air inlets 354 arranged in a honeycomb shape. Therefore, the air inlet resistance of the oil smoke is further reduced, and the effect of assisting in gathering the oil smoke is achieved. It is understood that, in the embodiment of the present invention, the intake assembly 306 is liftably provided at the mounting hole 102 of the cooktop 100. When the user uses the combined electrical appliance 1000 and needs to discharge smoke, the air intake assembly 306 may be raised above the cooking top 100 by a certain height to expose the plurality of second air intake groups 332, thereby achieving an effect of assisting in gathering smoke. When smoke evacuation is not required, the intake assembly 306 may be lowered to the same plane as the cooktop 100 such that the second plurality of intake vent sets 332 are located below the cooktop 100. In the illustrated embodiment, the second intake vent 354 is a hex-shaped aperture. In other embodiments, the second air inlet may be a circular hole. Of course, the second air inlet group may also adopt a plurality of second air inlets arranged in an array, or a plurality of single air inlets may be formed on the peripheral wall.

Referring to fig. 8, an angle area g formed by the air inlet axis a of the first air inlet 320 and the range of the second air inlet set 332 points to the range of the cooker 400 of the combined electrical appliance 1000. Therefore, the second air inlet set 332 can better play a role in assisting in gathering the smoke. Specifically, the range of the second air inlet group 332 determines the range of the angle area g, and when the range of the second air inlet group 332 is equal to the range of the cooker 400, the angle area g obtains the minimum value, which corresponds to the angle area g marked in fig. 8; when the range of the second intake vent group 332 is equal to the length of the third sidewall 338, the angle area g is the maximum value, which corresponds to the angle area h labeled in fig. 8. It should be noted that, in order to ensure the structural strength of the peripheral wall 318 at the same time, the first side wall 334 and the second side wall 336 are not provided with the second air inlet group 332, and in the case that the range of the cooker 400 is greater than the length of the third side wall 338 (as shown in fig. 9), in order to ensure the effect of assisting in gathering the smoke, the range of the second air inlet group 332 is set to be equal to the length of the third side wall 338 so as to obtain the maximum angle area g to assist in gathering the smoke.

A peripheral wall 318 is provided on the lower surface of the air inlet grille structure 316. The grill structure 316 and the peripheral wall 318 may be fixedly attached or removably attached.

In one example, the grill structure 316 overlaps the perimeter wall 318 by its own weight. Thus, the grill structure 316 is removably connected to the perimeter wall 318 for ease of installation and maintenance. Specifically, referring to fig. 5, the peripheral wall 318 includes a first side wall 334 and a second side wall 336 opposite to each other, the first side wall 334 is provided with a slot 356, the second side wall 336 is provided with a supporting block 358, the air inlet net structure 316 includes a first side edge 324 and a second side edge 326 opposite to each other, the first side wall 334 is opposite to the first side edge 324, the second side wall 336 is opposite to the second side edge 326, the first side edge 324 is provided with a pin 360 inserted into the slot 356, the second side edge 326 is provided with a groove 362, and the supporting block 358 is received in the groove 362. Thus, the air inlet net structure 316 is detachably connected with the peripheral wall 318 through the matching relationship between the pins 360 and the slots 356 and the matching relationship between the grooves 362 and the supporting blocks 358, so that the installation and maintenance are convenient. In the process of overlapping the air inlet net structure 316 to the peripheral wall 318, the pins 360 are inserted into the slots 356 under the action of the self-gravity of the air inlet net structure 316, and the supporting blocks 358 are received in the grooves 362, so that the air inlet net structure 316 is overlapped at a predetermined position of the peripheral wall 318. It can be understood that in other embodiments, the first side wall is provided with the pins, the second side wall is provided with the grooves, the first side edge is provided with the slots for accommodating the pins, the second side edge is provided with the supporting blocks, the supporting blocks can be accommodated in the grooves, and the wind network structure can be overlapped on the peripheral wall by means of self gravity.
