The blower 100 and the washing apparatus 200 having the same according to the embodiment of the present invention are described below with reference to the accompanying drawings.

It is understood that the blower 100 according to the embodiment of the present invention is not limited to be applied to the washing apparatus 200 having the structure shown in fig. 1, but may be applied to washing apparatuses having other structures, as will be readily understood by those skilled in the art.

Referring to fig. 1, a washing apparatus 200 according to some embodiments of the present invention may include a blower fan 100, a washing tub 201, an outflow runner 202, and a drainage runner 203 according to embodiments of the present invention. When the laundry is washed, the blower 100 is activated, and the air may sequentially pass through the blower 100, the outflow flow path 202, and the drainage path 203 into the washing tub 201. The gas in the washing tub 210 may be mixed with the liquid and wash the laundry. Here, the wind turbine 100 according to the embodiment of the present invention is obtained by the designer of the present invention based on the discovery of technical problems in the related art and the reason analysis.

In particular, in the related art, in the case that the washing effect of the washing method of the present invention is not ideal when the gas is introduced into the washing tub, the present inventors have studied and found that, in the washing method of introducing the gas, the introduction quality of the gas has a great influence on the washing effect, which results in a high requirement for the gas driving device, and a special gas driving device needs to be provided. The air outlet of the air driving device in the related art is dispersed, the air volume flows out from the periphery and the tail end of the fan, the air volume is dispersed, the air pressure is lowered, the air pressure is insufficient, and the air driving device is not beneficial to forming strong bubble water flow, so that the washing effect is influenced.

In view of this, the designer of the present application has designed a fan 200 with a new structure, which can improve the air outlet effect. Specifically, referring to fig. 1 and 2, a wind turbine 100 according to some embodiments of the present invention may include: the fan blade assembly comprises a shell assembly 10, a motor device 20 and a fan blade assembly 30.

Specifically, the casing assembly 10 has a plenum 101 and a plenum 102 therein, the plenum 101 has an air inlet 103 and an air outlet 104 on its wall, the air inlet 103 can communicate with the plenum 101 and the plenum 101, and the air outlet 104 can communicate with the plenum 101 and the plenum 102. The air collection chamber 102 has an air collection outlet 105 for discharging air. The motor arrangement 20 is arranged in the pressure chamber 101. The fan blade assembly 30 is arranged in the pressurizing cavity 101, and the fan blade assembly 30 can rotate under the driving of the motor device 20 so as to pressurize the gas passing through the fan blade assembly.

Therefore, under the driving of the motor device 20, the fan blade assembly 30 can rotate, external air can enter the pressurizing cavity 101 through the air inlet 103, and can flow into the air collecting cavity 102 from the air passing opening 104 after being pressurized by the fan blade assembly 30, the air collecting cavity 102 has the function of collecting air, so that the relatively dispersed air flowing out from the air passing opening 104 can be collected and then flows out from the air collecting outlet 105, the problem of air outlet dispersion can be improved, the air outlet is more concentrated, and the air pressure and the air volume can be favorably maintained. The fan 100 with the structure can be formed into a high-pressure fan or a booster fan, can be better adapted to the washing mode of introduced gas, and can improve the washing effect.

In the embodiment shown in fig. 1, in combination with the structure of the blower 200 shown in fig. 2, when the washing equipment 200 is used for washing, the blower 100 operates, the air inlet 103 is communicated with the atmosphere, the pressure is atmospheric pressure, and high-pressure air is formed through the pressurization effect of the fan blade assembly 30 and flows out through the air inlet 104; due to the arrangement of the air collecting cavity 102, the air flowing out from the air passing opening 104 can be concentrated to the air collecting outlet 105 to flow out, and the air collecting outlet 105 is connected with the outflow flow channel 202 to form high-pressure air with more sufficient air pressure and air quantity; the air flow is pushed by high pressure from the outflow flow path 202 through the draft duct 203 into the washing tub 201.

Because the fan 100 concentrates the originally dispersed wind to the wind collecting outlet 105 to flow out, enough wind pressure and wind quantity are ensured, so that the water flow in the washing tub 201 can be excited, and the water flow can be mixed with the air flow to form a powerful bubble water flow to continuously wash clothes; under the action of the bubble water flow, the clothes swing and roll along with the bubble water flow to clean dirt, partial bubbles break or penetrate through the clothes, and partial stains are gradually separated from the clothes under the action of the bubble penetration and breaking force, so that the clothes are more fully cleaned. Meanwhile, in the process, a small amount of detergent can form a large amount of foam, and clothes are fully immersed in the foam, so that the washing uniformity is greatly improved. Finally, the air flow may alternatively flow out from the upper portion of the washing tub 201.

The washing equipment 200 according to the embodiment of the invention adopts the fan 100 according to the embodiment of the invention, and can provide air with certain high pressure and air quantity in washing, so that the washing equipment 200 can also solve the technical problems of winding abrasion, uneven washing, much loss of lotion, easy residue and the like. Wherein, the specific air quantity and the numerical value of the air pressure of the air introduced by the fan 100 can be flexibly set according to the actual situation.

As shown in fig. 2, in some embodiments of the present invention, the supercharging chamber 101 may have a side peripheral chamber wall 110 and an end wall 120 disposed at one end of the side peripheral chamber wall 110, the side peripheral chamber wall 110 of the supercharging chamber 101 is provided with a plurality of air inlets 104, and the plurality of air inlets 104 are distributed along the circumference of the side peripheral chamber wall 110, so that wind energy can enter the wind collecting chamber 102 more rapidly and uniformly. In some alternative embodiments, the air vents 104 may also be provided in the end wall 120 in the event of an installation of the disturbance motor apparatus 20.

Further, the wind-collecting chamber 102 may include: a first cavity part 1021 and a second cavity part 1022. The first chamber section 1021 is peripheral to the pressurizing chamber 101, that is, the first chamber section 1021 is disposed around the pressurizing chamber 101. The first chamber section 1021 communicates with the air-passing opening 104. The second cavity part 1022 is located outside the end wall 120 and communicates with the first cavity part 1021. The end of the second cavity part 1022 far from the first cavity part 1021 is provided with a wind collection outlet 105.

Thus, as shown by arrows in fig. 3, the wind in the pressurizing chamber 101 can more easily enter the first chamber section 1021 through the plurality of wind passing openings 102, then pass through the second chamber section 1022, and flow out from the wind collecting outlet 105. The whole structure of the fan 100 is more compact, and the air outlet is smoother.

In combination with some embodiments of the present invention, the flow area of at least a portion of the second cavity 1022 adjacent to the wind-collecting outlet 105 decreases in the gas flow direction. In other words, the flow area of at least a part of the outlet section of the second chamber part 1022 is gradually decreased in the gas flow direction, and the gas flow direction is approximately from the first chamber part 1021 to the wind collecting outlet 105. Therefore, the second cavity 1022 with such a structure has a better wind collecting effect, has an accelerating effect on wind, can make the wind flow out of the wind collecting outlet 105 at a higher flow speed, has higher air pressure, and has more obvious promotion on the washing effect.

In some embodiments of the present invention, the flow area of the whole portion of the second cavity 1022 decreases in the flowing direction of the air, so that the air can be gradually and continuously accelerated in the second cavity 1022, and gradually and more concentrated in the flowing process, and the effect of accelerating and collecting the air is better, thereby further improving the washing of the laundry in the washing tub 201.

Alternatively, according to some embodiments of the present invention, the air inlet 103 may be disposed at a middle portion of one axial end (e.g., the lower axial end shown in fig. 2) of the pressure increasing chamber 101, which is more favorable for air outlet. Further, the air inlet 103 and the air collection outlet 105 may overlap in projection along the axial direction of the pressurizing chamber 101. From this, the air inlet and the air-out of fan 100 are roughly located same straight line, are more convenient for arrange, can reduce the amount of wind loss moreover.

According to some embodiments of the present invention, the total flow area of the air vents 104 may be larger than the flow area of the wind collection outlet 105. Thereby, the wind pressure and the wind volume at the wind collection outlet 105 can be further ensured. In some embodiments of the present invention, when the plurality of air inlets 104 is provided, the sum of the flow areas of the plurality of air inlets 104 is the total flow area.

The present invention is not particularly limited with respect to the specific structure of the housing assembly 10, and optionally, in some embodiments of the present invention, as shown with reference to fig. 2 and 3, the housing assembly 10 may include: a first housing 11 and a second housing 12. Specifically, the plenum 101 may be located within the first housing 11, and both the intake vent 103 and the overfire air vent 104 may be located in the first housing 11. The second housing 12 is covered on the first housing 11, and the second housing 12 and the first housing 11 can cooperate to define a wind collecting cavity 102, and a wind collecting outlet 105 is disposed on the second housing 12.

Thus, the housing assembly 10 may be divided into multiple sections for easier manufacture and installation. Alternatively, the second casing 12 may cover the first casing 11 completely or only a part of the second casing 12, for example, only a part of the first casing 11 adjacent to the air-passing opening 104, as required.

Taking the embodiment shown in fig. 2 as an example, the second housing 12 may optionally include: a first shell portion 121 and a second shell portion 122. The wind collecting outlet 105 may be disposed in the first shell portion 121, the second shell portion 122 may be connected to the first shell portion 121, and the second shell portion 122 and the first shell portion 121 may be cooperatively formed with the receiving space 106. The first housing 11 may be disposed in the accommodating space 106, and at least one of the first and second casing portions 121 and 122 is connected to the first housing 11, and the second casing portion 122 is provided with an air inlet 107 communicating the air inlet 103 with the outside.

Therefore, outside air enters from the air inlet 107, enters the supercharging cavity 101 through the air inlet 103, enters the air collecting cavity 102 through the air passing opening 104 after being supercharged by the supercharging cavity 101, and flows out from the air collecting outlet 105 after being collected. In this structure, the second casing 12 has a better protective effect on the first casing 11, and does not affect the air intake and the air outlet.

Alternatively, the first and second shell portions 121 and 122 may be coupled by welding, bonding, or threads, etc. The first housing 11 and the second housing 12 may be connected by welding, bonding, or screwing, or the first housing 11 may be abutted between the first housing part 121 and the second housing part 122. In addition, to improve strength, a reinforcing structure such as a convex knot may be provided on the first case 11 and the second case 12.

Alternatively, the air inlet 107 and the air inlet 103 may be coaxially disposed. Accordingly, the air can be smoothly introduced into the air inlet 103 from the air inlet 107, and the air inlet loss, noise, and the like can be reduced.

As shown in fig. 2 and 3, in some embodiments of the present invention, the motor apparatus 20 has a motor shaft 21 extending toward the intake vent 103. The fan blade assembly 30 may include: the supercharging fan blade 31 has a driving function and a supercharging function on wind, and the guide vane 32 has a guiding function on wind and can guide the wind to flow, so that the wind can flow along a preset path, and the flowability is better.

The supercharging blade 31 may include a base plate 311 and a blade 312, the base plate 311 may be connected to the motor shaft 21, and the blade 312 may be provided on a side surface (e.g., an upper side surface shown in fig. 2) of the base plate 311 facing the air intake 103. The guide vane 32 may be provided on a side surface (e.g., a lower side surface shown in fig. 2) of the base plate 311 facing away from the blades 312. Thus, the wind may be pressurized by the blades 312 and then flow toward the air inlet 104 through the diversion of the guide vanes 32.

In the above structure, the fan blade assembly 30 is closer to the air inlet 103 than the motor device 20, which is more beneficial to driving the air into the pressurizing cavity 101, and the pressurized air is easier to enter into the air collecting cavity 102 from the air inlet 104; meanwhile, the wind can contact with the motor device 20 in the flowing process under the flow guidance of the flow deflector 32, and the motor device 20 can also play a certain role in cooling.

The washing apparatus according to an embodiment of the present invention may be a washing machine or a shoe washing machine, etc., and other configurations and operations of the washing apparatus are known to those skilled in the art and will not be described in detail herein.
