Description

Technical Field

[0001] The present invention relates to the technical field of fans, and more particularly to a diffuser and an electrical appliance. Background Art

[0002] A fan is a machine that relies on mechanical energy to increase the gas pressure and discharge the gas, and has a wide range of applications in household appliances.

[0003] In the related art, a fan generally includes an impeller and a diffuser. The impeller rotates to generate an air flow, which is discharged after being diffused by the diffuser. A fan generally has a preset design flow rate, and the blade angle of the corresponding diffuser is set to correspond to the design flow rate to achieve high-efficiency operation of the fan at the design flow rate. However, the diffuser usually can only meet the high-efficiency operation under a certain working condition. When the working condition changes, the efficiency decreases due to the mismatch with the incoming flow of different parameters. Summary of the Invention

[0004] The present invention aims to at least solve or improve the technical problem that the fixed blade angle of the diffuser in the prior art can only meet one air flow rate.

[0005] To this end, a first aspect of the present invention provides a diffuser.

[0006] A second aspect of the present invention provides an electrical appliance.

[0007] In view of this, according to the first aspect of the present invention, a diffuser is provided, including: a main body, the main body including a peripheral side wall; a plurality of blades movably disposed on the peripheral side wall; an adjusting assembly connected to the blades for adjusting the positions of the blades.

[0008] The diffuser provided by the present invention includes a main body, blades and an adjusting assembly. The blades are disposed on the peripheral side wall of the main body, and the blades are movable relative to the main body. The adjusting assembly is connected to the blades, and the adjusting assembly can adjust the positions of the blades, thereby realizing the adjustment of the angle of the blades relative to the axis of the main body, so that the diffuser can meet different air flow rates, that is, under different working conditions of the electrical appliance, it can have better efficiency.

[0009] In addition, the diffuser according to the above technical solution provided by the present invention may further have the following additional technical features:

[0010] In some embodiments, optionally, the peripheral side wall includes a plurality of mounting holes and a plurality of first sliding grooves. The blade includes: a first connecting portion rotatably inserted into the mounting hole; a second connecting portion, the second connecting portion being slidably disposed in the first sliding groove, and the adjusting assembly is connected to the second connecting portion, and the adjusting assembly can drive the blade to rotate through the second connecting portion.

[0011] In this embodiment, the circumferential sidewall includes a plurality of mounting holes and a plurality of first sliding channels. Among them, one mounting hole and one first sliding channel correspond to a group, and one vane cooperates with a group of mounting holes and first sliding channels.

[0012] The vane includes a first connecting portion and a second connecting portion. The first connecting portion is rotatably inserted into the mounting hole, and the second connecting portion is slidably disposed in the first sliding channel. The adjusting assembly is connected to the second connecting portion. Thus, the adjusting assembly can adjust the position of the second connecting portion in the first sliding channel. During the movement of the second connecting portion in the first sliding channel, the vane rotates around the first connecting portion as the axis, thereby adjusting the axial angle of the vane relative to the main body, that is, the vane moves in a rotational manner. Such a movement mode is stable and reliable, improving the reliability of the diffuser.

[0013] In some embodiments, optionally, the adjusting assembly includes: an adjusting member, and the second connecting portion of each vane is connected to the adjusting member.

[0014] In this embodiment, the adjusting assembly includes an adjusting member, and the second connecting portion of each vane is connected to the adjusting member. That is, one adjusting member can adjust all the vanes simultaneously, ensuring the unity of the angles of multiple vanes and ensuring the pressure boosting effect of the diffuser.

[0015] In some embodiments, optionally, the adjusting member includes a plurality of second sliding channels, and the second connecting portion is slidably inserted into the second sliding channels. The extending directions of the first sliding channel and the second sliding channels are different.

[0016] In this embodiment, the adjusting member includes a plurality of second sliding channels, and one second connecting portion cooperates with one second sliding channel. And the second connecting portion is slidably inserted into the second sliding channel. Since the vane rotates, the movement trajectory of the second connecting portion is an arc. Therefore, setting the extending directions of the first sliding channel and the second sliding channels to be different can decompose the arc-shaped movement trajectory, avoiding interference between the second connecting portion and the second sliding channel and ensuring the rotation effect of the vane.

[0017] In some embodiments, optionally, the adjusting member has an annular structure, and a plurality of second sliding channels are distributed on the circumferential side of the adjusting member.

[0018] In this embodiment, the adjusting member has an annular structure, reducing the weight of the adjusting member and the power requirement for the movement of the adjusting member. And a plurality of second sliding channels are distributed on the circumferential side of the adjusting member to ensure one-to-one correspondence between the second sliding channels and the second connecting portions of the vanes.

[0019] In some embodiments, optionally, the adjusting assembly further includes: a rack, connected to the adjusting member, and the rack is used to drive the adjusting member to move.

[0020] In this embodiment, the adjusting assembly further includes a rack connected to the adjusting member. The rack can drive the adjusting member to move. The cooperation between the rack and the gear can achieve a locking effect to ensure that the blade can stay at the required position. Moreover, the movement accuracy of the rack is high, which improves the reliability of the matching between the diffuser and the air flow rate.

[0021] In some embodiments, optionally, the circumferential side wall includes a third slideway, and the rack is embedded in the third slideway.

[0022] In this embodiment, the circumferential side wall includes a third slideway, and the rack is embedded in the third slideway and can move in the third slideway, thereby improving the stability of the movement of the rack.

[0023] In some embodiments, optionally, the blade includes a flexible portion, and the flexible portion is in contact with the main body.

[0024] In this embodiment, the blade includes a flexible portion, and the flexible portion is in contact with the main body. Since the blade is movable relative to the main body, therefore, by providing the flexible portion on the blade and making the flexible portion in contact with the main body, after the blade changes the angle, the blade still fits tightly with the main body, reducing the possibility of a gap appearing between the main body and the blade.

[0025] In some embodiments, optionally, the circumferential side wall has an annular structure, and the adjusting assembly is located inside the circumferential side wall.

[0026] In this embodiment, the circumferential side wall has an annular structure, and the adjusting assembly is arranged inside the circumferential side wall, thereby reducing the influence of the adjusting assembly on the air flow.

[0027] According to the second aspect of the present invention, the present invention provides an electrical device, including: a diffuser as proposed in the embodiment of the first aspect.

[0028] For the electrical device proposed by the present invention, since it includes the diffuser as proposed in the embodiment of the first aspect, therefore, it has all the beneficial effects of the diffuser as proposed in the embodiment of the first aspect, which will not be elaborated one by one here.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0043] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0044] The following refers to Figures 1 to 9 to describe the diffuser 100 and the electrical equipment provided according to some embodiments of the present invention.

[0045] As shown Figures 1 to 3 In accordance with the first aspect of the present invention, a diffuser 100 is provided. The diffuser 100 includes a main body 110, blades 120, and an adjustment assembly 130. The main body 110 includes a peripheral side wall 112. The number of the blades 120 is plural. The plural blades 120 are movably disposed on the peripheral side wall 112. The adjustment assembly 130 is connected to each of the plural blades 120, and the adjustment assembly 130 can adjust the positions of the blades 120.

[0046] The diffuser 100 provided by the present invention includes a main body 110, blades 120, and an adjustment assembly 130. The blades 120 are disposed on the peripheral side wall 112 of the main body 110. Moreover, the blades 120 are movable relative to the main body 110. The adjustment assembly 130 is connected to the blades 120, and the adjustment assembly 130 can adjust the positions of the blades 120, thereby realizing the adjustment of the axial angle of the blades 120 relative to the main body 110, so that the diffuser 100 can meet different air flow rates, that is, the diffuser 100 can have better efficiency under different operating conditions of the electrical equipment.

[0047] That is, the diffuser 100 provided by the present invention changes the structure of the axial flow diffuser 100 by adjusting the angles of the adjustable blades 120, so that it can match air flows with different parameters and improve the performance of electrical equipment under different operating conditions.

[0048] As shown Figure 1 、 Figure 6 and Figure 7 In some embodiments, optionally, the blade 120 includes a first connection portion 122 and a second connection portion 124. The first connection portion 122 and the second connection portion 124 may be located on the same side of the blade 120. A plurality of mounting holes 114 and a plurality of first sliding grooves 116 are provided on the peripheral side wall 112. The number of the mounting holes 114, the number of the first sliding grooves 116, and the number of the blades 120 are the same. The first connection portion 122 of one blade 120 is inserted into one mounting hole 114, and moreover, the first connection portion 122 can rotate relative to the mounting hole 114. The second connection portion 124 of one blade 120 is inserted into one first sliding groove 116, and moreover, the second connection portion 124 can slide relative to the first sliding groove 116. Further, when the second connection portion 124 slides in the first sliding groove, the first connection portion 122 rotates in the mounting hole 114, thereby adjusting the inclination angle of the blade 120.

[0049] In this embodiment, the peripheral side wall 112 includes a plurality of mounting holes 114 and a plurality of first sliding grooves 116. Among them, one mounting hole 114 and one first sliding groove 116 form a group, and one blade 120 cooperates with a group of mounting holes 114 and first sliding grooves 116.

[0050] The blade 120 includes a first connecting portion 122 and a second connecting portion 124. The first connecting portion 122 is rotatably inserted into the mounting hole 114, and the second connecting portion 124 is slidably disposed in the first slideway 116. The adjusting assembly 130 is connected to the second connecting portion 124. Thus, the adjusting assembly 130 can adjust the position of the second connecting portion 124 in the first slideway 116. During the movement of the second connecting portion 124 in the first slideway 116, the blade 120 rotates about the first connecting portion 122 as the axis, thereby adjusting the axial angle of the blade 120 relative to the main body 110, that is, the blade 120 moves in a rotational manner. Such a movement mode is stable and reliable, improving the reliability of the diffuser 100. When the angle of the blade 120 changes, the air duct structure formed between adjacent blades 120 is changed, thereby changing the air flow rate matched by the diffuser 100.

[0051] Wherein, the first connecting portion 122 may be a columnar structure, and the second connecting portion 124 may be a columnar structure.

[0052] Specifically, as Figure 2 and Figure 3 shown, the adjusting assembly 130 can adjust the second connecting portion 124 of the blade 120 to move along the first slideway 116 in the A direction or the B direction, thereby adjusting the angle of the blade 120 relative to the axis, adjusting the optimal air flow rate corresponding to the diffuser 100, thereby expanding the applicable range of the diffuser 100 and improving the efficiency of the electrical equipment.

[0053] The diffuser 100 provided by the present invention includes a main body 110 and a plurality of blades 120. The plurality of blades 120 are circumferentially and spaced apart on the main body 110. It further includes an adjusting assembly 130 fixedly connected to each blade 120 one by one for adjusting the angle of the blade 120. Each blade 120 can be driven to rotate along with the axial movement of the adjusting assembly 130, thereby adjusting the installation angle of the blade 120.

[0054] By changing the installation angle of the blade 120, it is possible to make the flow channels between the blades 120 of the diffuser 100 cooperate with airflows of different parameters, thereby adapting to different working conditions of the electrical equipment, which is beneficial to the electrical equipment to achieve higher efficiency under different working conditions.

[0055] As Figure 1 、 Figure 5 and Figure 8 shown, in some embodiments, optionally, the adjusting assembly 130 includes an adjusting member 132. The adjusting member 132 is connected to the second connecting portions 124 of the plurality of blades 120. Thus, one adjusting member 132 can adjust all the blades 120 simultaneously.

[0056] In this embodiment, the adjusting assembly 130 includes an adjusting member 132. The second connecting portion 124 of each blade 120 is connected to the adjusting member 132. That is, one adjusting member 132 can adjust all the blades 120 simultaneously, ensuring the unity of the angles of the multiple blades 120 and the pressure boosting effect of the diffuser 100.

[0057] As Figure 1 shown, the adjusting member 132 can move along the axial direction of the main body 110 in the W direction or the V direction, thereby driving the second connecting portion 124 to move along the first slideway 116 in the A direction or the B direction.

[0058] As Figure 1 、 Figure 5 and Figure 8 shown, in some embodiments, optionally, the adjusting member 132 includes a plurality of second slideways 134. The second connecting portion 124 is slidably inserted into the second slideway 134, and the extending directions of the first slideway 116 and the second slideway 134 are different.

[0059] In this embodiment, the adjusting member 132 includes a plurality of second slideways 134. One second connecting portion 124 cooperates with one second slideway 134, and the second slideway 134 is slidably inserted into the second slideway 134. Since the blade 120 rotates, the movement track of the second connecting portion 124 is an arc. Therefore, setting the extending directions of the first slideway 116 and the second slideway 134 to be different can decompose the arc-shaped movement track and avoid interference between the second connecting portion 124 and the second slideway 134, ensuring the rotation effect of the blade 120.

[0060] Specifically, as Figure 9 shown, the extending direction N of the second slideway 134 and the extending direction M of the first slideway 116 form a certain angle. Further, when the adjusting member 132 moves along the axial direction, the second connecting portion 124 moves obliquely or in an arc along the first slideway 116, thereby realizing the adjustment of the angle of the blade 120 relative to the axial direction.

[0061] As Figure 1 and Figure 5 shown, in some embodiments, optionally, the adjusting member 132 has an annular structure, and a plurality of second slideways 134 are distributed on the circumferential side of the adjusting member 132.

[0062] In this embodiment, the adjusting member 132 has an annular structure, reducing the weight of the adjusting member 132 and the power requirement for the movement of the adjusting member 132. Moreover, a plurality of second slideways 134 are distributed on the circumferential side of the adjusting member 132 to ensure one-to-one correspondence between the second slideways 134 and the second connecting portions 124 of the blades 120.

[0063] Specifically, the second slideway 134 is uniformly arranged on the adjusting member 132.

[0064] As Figure 1 , Figure 5 and Figure 8 shown, in some embodiments, optionally, the adjusting assembly 130 further includes a rack 136 connected to the adjusting member 132, and the rack 136 is used to drive the adjusting member 132 to move, wherein the rack 136 protrudes from one side of the adjusting member 132.

[0065] In this embodiment, the adjusting assembly 130 further includes a rack 136 connected to the adjusting member 132. The rack 136 can drive the adjusting member 132 to move. The cooperation between the rack 136 and the gear 140 can achieve a locking effect to ensure that the blade 120 can stay at the required position. Moreover, the movement accuracy of the rack 136 is high, improving the reliability of the diffuser 100 in matching with the air flow rate.

[0066] Specifically, as Figure 8 shown, the rack 136 can cooperate with the gear 140, so that when the gear 140 rotates, the adjusting member 132 can be driven to move by the rack 136.

[0067] As Figure 1 and Figure 4 shown, in some embodiments, optionally, the circumferential side wall 112 includes a third slideway 118, and the rack 136 is embedded in the third slideway 118.

[0068] In this embodiment, the circumferential side wall 112 includes a third slideway 118, and the rack 136 is embedded in the third slideway 118 and can move in the third slideway 118, thereby improving the stability of the movement of the rack 136.

[0069] Wherein, the number of the racks 136 can be multiple, and the multiple racks 136 are embedded in the circumferential side wall 112 in different directions, thereby improving the stability of the movement of the adjusting member 132.

[0070] Or, as Figure 3 and Figure 5 shown, a guiding member 138 is further arranged on the adjusting member 132, and the guiding member 138 is embedded in the circumferential side wall 112, thereby increasing the stability of the movement of the adjusting member 132.

[0071] As Figure 7 shown, in some embodiments, optionally, the blade 120 includes a flexible portion 126, and the flexible portion 126 is in contact with the main body 110.

[0072] In this embodiment, the blade 120 includes a flexible portion 126. The flexible portion 126 is in contact with the main body 110. Since the blade 120 is movable relative to the main body 110, a flexible portion 126 is provided on the blade 120. The flexible portion 126 is in contact with the main body 110, so that after the blade 120 changes its angle, the blade 120 still fits closely with the main body 110, reducing the possibility of a gap appearing between the main body 110 and the blade 120.

[0073] Specifically, the flexible portion 126 can be made of rubber, plastic or resin.

[0074] Such as Figure 1 、 Figure 2 and Figure 4 As shown in

[0075] In this embodiment, the peripheral side wall 112 has an annular structure, and the adjusting assembly 130 is located inside the peripheral side wall 112.
