To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or uses of other materials.

In the related technology, the air inlet of the integrated kitchen appliance adopts an integral rectangular opening, the air inlet quantity of the whole air inlet is uniformly distributed, and the two ends of the air inlet do not have obvious large air quantity to capture the oil smoke quickly when the stir-frying is carried out. This makes the effect of sucking the oil smoke poor. Moreover, the fan is arranged in the smoking air duct, so that the noise generated by the fan can be directly transmitted out through the air duct, and the radiated noise of the fan is larger.

Referring to fig. 1 to 6, a fan assembly 100 according to an embodiment of the present invention is provided, where the fan assembly 100 includes a horizontal fan 10 and an air duct member 20; the horizontal fan 10 comprises a volute 11, and the top of the volute 11 is provided with a first air inlet 111; the air duct member 20 includes an air intake member 21 and a connecting member 22; the air inlet piece 21 is connected above the connecting piece 22, and the connecting piece 22 is connected with the volute casing 11; the air inlet member 21 is provided with an air inlet duct 215, and the connecting member 22 is provided with a connecting duct 223 communicating the first air inlet 111 and the air inlet duct 215; the connection member 22 is configured to make the airflow entering from the intake duct 215 form a rotating airflow at the connection duct 223 and enter the first intake opening 111.

In the above fan assembly 100, the connecting member 22 forms the rotating airflow entering the first air inlet 111 of the volute 11 at the connecting air duct 223, so that noise caused by collision of the airflow at the first air inlet 111 can be reduced or avoided, and noise performance of the fan assembly 100 is improved.

In addition, by adopting the arrangement mode that the horizontal fan 10 is connected with the air duct member 20, the horizontal fan 10 can be far away from the air inlet of the air inlet duct 215, so that the distance between the horizontal fan 10 and a user can be increased, the noise radiated to the user can be obviously reduced at the same rotating speed, and the user experience is improved.

Specifically, the connecting member 22 connects the rotating airflow formed by the air duct 223, so that the airflow enters the volute 11 from the first air inlet 111 in a spiral shape, which can effectively reduce or avoid the mutual collision of the airflow, reduce the collision between the airflow and the connecting member 22 and the first air inlet 111, and reduce the flowing resistance of the airflow, thereby ensuring that the flowing speed of the airflow is not attenuated, and improving the oil smoke absorption effect of the fan assembly 100.

The horizontal fan 10 further comprises a motor 12 and an impeller 13, wherein the motor 12 is connected with the impeller 13 and is used for driving the impeller 13 to rotate. In the embodiment of the present invention, the rotation axis R of the impeller 13 of the horizontal fan 10 is perpendicular to the horizontal plane.

The fan assembly 100 of embodiments of the present invention may be used in an integrated kitchen appliance. The fan assembly 100 may be used to provide suction to draw and exhaust fumes around the integrated kitchen appliance into the fan assembly 100.

The horizontal fan 10 of the embodiment of the invention can be arranged at the bottom of the integrated kitchen appliance, the air inlet part 21 can be arranged perpendicular to the horizontal fan 10, the air inlet part 21 can be arranged at the back of the integrated kitchen appliance, and meanwhile, the connecting part 22 is arranged between the air inlet part 21 and the horizontal fan 10, so that the airflow can smoothly change the flow direction, and the airflow flows along the direction from the upper part of the kitchen range of the integrated kitchen appliance, the air inlet part 21, the connecting part 22 and the horizontal fan 10 to the outside of the kitchen. The arrangement mode is beneficial to reducing the front and back thickness of the integrated kitchen appliance, and can also effectively utilize the bottom space of the integrated kitchen appliance and optimize the kitchen space utilization rate of the integrated kitchen appliance.

The air duct member 20 may be made of a metal material through a stamping or welding process. In one example, the air duct member 20 may be formed by stamping a galvanized sheet and then assembling the sheet by a welding process. The air duct member 20 has high corrosion resistance, is not easy to damage, and does not cause oil smoke leakage. Generally, when the air inlet member 21 and the connecting member 22 are installed, the air inlet member 21 and the connecting member 22 can be connected and fixed in a welding manner, and the joint is sealed by using metal sealant to prevent oil smoke from leaking.

Likewise, the volute casing 11 may also be made of metal by a stamping and welding process. The volute casing 11 and the connecting piece 22 can also be connected by welding and metal sealing glue. It is understood that in other embodiments, the material of the volute and the air duct may be other materials, and is not particularly limited herein.

Referring to fig. 1 to 2, in some embodiments, the connecting member 22 is installed on the top of the volute casing 11, and the volute casing 11 is located outside the air duct member 20; referring to fig. 5-6, in some embodiments, the volute 11 is located within the connector 22.

Thus, when the volute casing 11 is located outside the air duct member 20, as shown in fig. 1, the air flow in the air duct member 20 can uniformly flow into the volute casing 11 from the connecting member 22, which is beneficial to improving the smoothness of the air flow.

When the volute 11 is located in the connecting member 22, as shown in fig. 5, the overall occupied space of the fan assembly 100 can be reduced, so that the fan assembly 100 is more compact. In the embodiment shown in fig. 5, the volute is disposed in the connecting duct 223, and the top of the volute is spaced from the top surface of the connecting duct 223 to allow air to enter the volute 11.

In some embodiments, the connection member 22 includes a connection portion 221 and an air inlet portion 222, the connection portion 221 connects the air inlet member 21 and the air inlet portion 222, and the air inlet portion 222 forms a rotating air flow.

Therefore, the rotating airflow formed in the air inlet portion 222 can reduce the airflow velocity reduction caused by airflow collision, thereby ensuring the oil smoke absorption effect of the fan assembly 100.

Specifically, the distance between the top and bottom surfaces of the air inlet portion 222 and the connection portion 221 may be equal in size, that is, the heights of the air inlet portion 222 and the connection portion 221 are equal. To reduce the resistance experienced by the airflow as it circulates within the connector 22.

In some embodiments, the number of the connection parts 221 is two, and each connection part 221 connects the air inlet member 21 and the air inlet part 222. It is understood that in other embodiments, the number of the connection portions 221 may be one or more than two, which may ensure that the swirling airflow is formed at the first air inlet.

Thus, the air flows respectively entering the air inlet portion 222 from the two connecting portions 221 can form a rotating air flow in the air inlet portion 222, so that the reduction of the air flow velocity caused by the collision of the air flows is reduced, the air flow velocity is ensured, and the oil smoke absorption effect of the fan assembly 100 is ensured.

In some embodiments, the two connection portions 221 may be directly disposed at both ends of the air inlet portion 222. Therefore, the flow velocity of the air flow at the two ends of the air inlet portion 222 can be increased, so that the air volume can be distributed to the area where the oil smoke is easy to escape, and the oil smoke absorption effect of the fan assembly 100 is improved.

Referring to fig. 1 and 2, in some embodiments, a fan assembly 100 includes an air inlet ring 30. The air inlet ring 30 is disposed at the first air inlet 111. The air inlet portion 222 covers the air inlet ring 30, and the connecting portion 221 includes a windward side wall 2211 and a leeward side wall 2212. The windward side wall 2211 is tangent to the outer edge of the air inlet ring 30.

Thus, the windward side wall 2211 is tangent to the outer edge of the air inlet ring 30, so that the resistance of the air flow entering the air inlet portion 222 and the volute casing 11 from the connecting portion 221 can be reduced, the two air flows entering from the two connecting portions 221 can be separated from each other, the turbulence generated in the air inlet portion 222 due to the direct collision of the air flows is avoided, the smoothness of the air flow circulation is improved, and the noise of the fan assembly 100 can be reduced.

Specifically, the shape of the air inlet ring 30 may be a circular ring, the shape of the arc-shaped outer wall covering the air inlet portion 222 of the air inlet ring 30 may be a circle, the arc-shaped side wall 2222 is perpendicular to the outer edge of the air inlet ring 30, and the diameter of the arc-shaped outer wall is equal to the diameter of the outer edge of the air inlet ring 30, so as to reduce the resistance generated by the casing of the volute casing 11 when the airflow enters the volute casing 11 from the first air inlet 111.

Since the diameter of the arc-shaped outer wall is equivalent to the diameter of the outer edge of the air inlet ring 30, the windward side wall 2211 and the arc-shaped side wall 2222 are also tangent.

Referring to fig. 1, the two windward side walls 2211 of the two connecting portions are tangent to the arc-shaped outer wall 2222, and the two windward side walls 2211 may be disposed on different sides of the arc-shaped outer wall, so as to ensure that the airflows flowing into the air inlet portion 222 from the two connecting portions 221 do not collide directly, but respectively flow spirally along the two arc-shaped side walls 2222, and then are sucked into the volute 11 by the horizontal fan 10.

Referring to fig. 1, in some embodiments, the connection 221 includes a windward side wall 2211 and a leeward side wall 2212. An extension line of the leeward side wall 2212 intersects with the rotation axis R of the horizontal fan 10.

Thus, the width of the connecting portion 221 can be ensured to circulate sufficient air flow, and the air flow entering the air inlet portion 222 from the two connecting portions 221 can be ensured not to collide directly, so that turbulence in the air inlet portion 222 is avoided, the smoothness of air flow flowing is improved, and the noise of the fan assembly 100 is reduced.

Specifically, the extension lines of the two leeward side walls of the two connecting portions are respectively E1 and E2, and when the extension line of the leeward side wall 2212 does not intersect with the rotation axis R of the horizontal fan 10, two phenomena occur, namely, the air duct of the connecting portion 221 is too narrow, the air flow circulation is reduced, and the oil smoke removal effect of the fan assembly 100 is reduced; secondly, the air duct of the connecting portion 221 is too wide, and the air flows entering the air inlet portion 222 from the two connecting portions 221 directly collide with each other, so that turbulence is generated in the air inlet portion 222, the flow velocity of the air flow is affected, and the noise of the fan assembly 100 can be reduced. Therefore, when the extension lines E1 and E2 of the two leeward side walls 2212 intersect with the rotation axis R of the horizontal fan 10, the arrangement mode is to avoid turbulence in the air inlet portion 222 on the premise of increasing the air passage of the connecting portion 221 as much as possible.

Referring to FIG. 2, in some embodiments, the intake collar 30 includes an upper surface 31. The upper surface 31 is an upwardly convex curved surface.

Thus, the resistance to airflow can be reduced, the fluency can be improved, and the noise of the fan assembly 100 can be reduced.

Specifically, referring to fig. 2, the air inlet ring 30 may be a circular thin plate, an upper surface 31 of the air inlet ring 30 protrudes upward, and an inner edge of the air inlet ring 30 is lower than a horizontal plane where an outer edge of the air inlet ring 30 is located, so that the air flow can smoothly flow into the volute casing 11 along the upper surface 31 of the air inlet ring 30.

Referring to FIG. 2, in some embodiments, the height a of the connector 22 is 0.3-3 times the height b of the horizontal fan 10. In this way, the air flow of the fan assembly 100 can be ensured and the occupied space of the connector 22 can be reduced.

It can be understood that, when the height a of the connecting member 22 is too high, the space inside the connecting member 22 is increased, the airflow rate that the connecting member 22 can accommodate and circulate is increased, but the airflow rate of the fan assembly 100 is determined by the horizontal fan 10 and the air inlet member 21, the connecting member 22 only plays a role of conveying airflow in an intermediate link, and excessively increasing the height a of the connecting member 22 does not improve the overall suction airflow rate of the fan assembly 100, but increases the occupied space of the connecting member 22, thereby increasing the occupied space of the fan assembly 100.

When the height a of the connector 22 is too low, the inner space of the connector 22 is too small to accommodate and circulate too low an amount of air, which provides resistance to the air flowing through the connector 22 and reduces the overall air flow rate of the fan assembly 100.

Therefore, the height a of the connecting member 22 should match the specification of the height b of the horizontal fan 10 and the air inlet member 21, and in the embodiment of the present invention, when the height a of the connecting member 22 is 0.3 to 3 times of the height b of the horizontal fan 10, the connecting member 22 can accommodate and circulate the air flow rate matching the air flow rate of the horizontal fan 10.

Referring to fig. 1 and 2, in some embodiments, the air inlet duct 215 includes a second air inlet 211 and two branch air ducts 212, the two branch air ducts 212 are respectively located at two ends of the second air inlet 211, and the branch air ducts 212 communicate with the second air inlet 211 and the connecting air duct 223.

The two ends of the second air inlet 211 are respectively connected with the split air duct 212, so that when the horizontal fan 10 works, a large suction force can be generated at the two ends of the second air inlet 211 to capture oil smoke, and the air volume is distributed to an area where the oil smoke is easy to escape, so that the oil smoke absorption effect of the fan assembly 100 can be improved.

In some embodiments, the air inlet member may be a plate-shaped hollow member, and the air inlet duct formed in the air inlet member is a single duct, and the lower end of the duct is connected to the duct. The two connecting air channels can be respectively connected to two sides of the lower end of the air channel, one connecting air channel can be connected with the lower end of the air channel, more than two connecting air channels can be connected with the lower end of the air channel, and the rotating air flow at the first air inlet can be guaranteed.

Referring to fig. 4, fig. 4 shows the flowing direction of the air flow in the air duct member 20, after the air flow flows into the air inlet portion 21 from the second air inlet 211, the air flow is divided into two divided air ducts 212, and then flows into the connecting portion 22 from the two divided air ducts 212, and finally flows spirally and is sucked by the horizontal fan 10.

Referring to fig. 2 and 8, in some embodiments, the thickness c of the air intake member 21 is the same as the thickness d of the head duct 310. The head air duct 310 is an air duct provided in the head 300 of the integrated kitchen appliance. Thus, on the premise of ensuring the air flow of the fan assembly 100, the flow resistance of the air flow when the head air duct 310 flows to the air inlet member 21 can be reduced.

It can be understood that when the thickness c of the air inlet member 21 is greater than the thickness d of the head air duct 310, the inner space of the air inlet member 21 is too large, but the air inlet amount is determined by the thickness of the head air duct 310, and has no influence on the air flow amount of the whole fan assembly 100. When the thickness c of the air inlet member 21 is smaller than the thickness d of the head air duct 310, the air flow flowing from the head air duct 310 to the air inlet member 21 may receive resistance caused by the thickness difference, thereby reducing the overall air flow of the fan assembly 100.

Therefore, in the present embodiment, the thickness c of the air inlet member 21 is the same as the thickness d of the head duct 310. It should be noted that the same may mean the same or that the error is within a desired range.

Referring to fig. 2, 3 and 8, in some embodiments, the width e of the diversion duct 212 is not less than 1.5 times the thickness d of the head duct 310. The head air duct 310 is an air duct provided in the head 300 of the integrated kitchen appliance.

In this way, the air flow rates of the two diversion air ducts 212 can be matched with the air flow rate of the horizontal fan 10, and the air flow velocity of the diversion air ducts 212 is also ensured.

It can be understood that when the width e of the branch air duct 212 is too narrow, although the flow rate of the circulating air flow in the branch air duct 212 is ensured, the air flow of the fan assembly 100 as a whole is reduced, and the oil smoke absorption effect of the fan assembly 100 is reduced.

Therefore, in the embodiment of the present invention, the width e of the diverging air duct 212 is not less than 1.5 times the thickness d of the head air duct 310, so as to match the intake air amount of the head air duct.

Referring to fig. 1-3, in some embodiments, the air intake component 21 includes a transverse portion 213 and two longitudinal portions 214. Two longitudinal portions 214 are connected to both ends of the transverse portion 213, respectively, and the connecting member 22 connects the two longitudinal portions 214. The transverse portion 213 is provided with a second air inlet 211 and a transverse air duct 2131. The longitudinal portion 214 is opened with a diversion air channel 212. The transverse air duct 2131 communicates with the second air inlet 211 and the branch air duct 212.

Thus, the diversion air channel 212 can increase a large suction force at the two ends of the transverse air channel 2131, so that the air volume can be distributed to an area where oil smoke easily escapes, and the oil smoke absorption effect of the fan assembly 100 is improved.

Referring to fig. 1, in some embodiments, the transverse air chute 2131 is tapered from the middle to the ends. In this way, resistance when the airflow flows from the transverse air duct 2131 to the branch air duct 212 can be reduced, and the oil smoke absorption effect of the horizontal fan 10 can be improved.

Referring to fig. 3 and 8, in some embodiments, the highest Z of the bottom of the transverse air chute 2131 is not lower than the lowest surface 215 of the cooktop 210. The hob 210 is a kitchen appliance integrated hob 210.

Therefore, the space between the lower part of the transverse air duct 2131 and the two shunt air ducts 212 can be reasonably utilized, so that other accessory electric appliances of the integrated kitchen electric appliance can have larger installation space, and the space utilization rate of the integrated kitchen electric appliance is improved.

In particular, the cooktop 210 includes a housing and heating elements and related controls within the housing, and the lowermost surface 215 of the cooktop 210 can be understood to be the lowermost surface of the cooktop 210 housing. The heating element can be an electromagnetic coil or a burner, and the control element can be a control element for controlling the operation of the cooker.

The accessory appliances, which may include microwave ovens, dishwashers, etc., are disposed below the cooktop 210.

Referring to fig. 1 and 2, in some embodiments, a horizontal wind turbine 10 includes a motor 12 and an impeller 13. The motor 12 and the impeller 13 are located in the volute 11, and the impeller 13 is fixed to the rotating shaft of the motor 12. Referring to fig. 5 and 6, in some embodiments, the impeller 13 is located inside the volute 11, the motor 12 is located outside the volute 11, and the impeller 13 is connected to the rotating shaft of the motor 12 through a transmission member.

In this way, the motor 12 can drive the impeller 13 to form an air flow in the volute 11, so as to suck the oil smoke into the fan assembly 100 through the connecting member 22 and the air inlet member 21.
