A laundry treating apparatus 1000 according to an embodiment of the present utility model is described below with reference to fig. 1 to 17.

As shown in fig. 1 to 2, the laundry treating apparatus 1000 according to an embodiment of the present utility model includes a cabinet assembly 150 and a first laundry treating module 300, the cabinet assembly 150 defining a receiving space 110. The first laundry treating module 300 is provided in the receiving space 110 such that the first laundry treating module 300 can be simultaneously protected by the cabinet assembly 150.

The first laundry treating module 300 includes a first laundry treating drum 310 and a wind wheel 340, the wind wheel 340 is disposed at a rear side of the first laundry treating drum 310, the wind wheel 340 operates to drive air into the first laundry treating drum 310, the air is used to contact wet laundry in the first laundry treating drum 310 and take away moisture on the wet laundry to achieve a drying process of the laundry. Because the first laundry treatment module 300 is mainly used for drying laundry, the laundry treatment device 1000 of the present application can have a function of drying laundry by arranging the first laundry treatment module 300 in the accommodating space 110, so as to further enrich the functions of the laundry treatment device 1000 and improve the user experience.

Wherein a distance h between the rotation center of the wind wheel 340 and the center of the first laundry treating drum 310 in the up-down direction is 288mm to 318mm. For example, h may be 288mm, 290mm, 295mm, 300mm, 305mm, 310, 318mm, etc.

According to the laundry treating apparatus 1000 of the embodiment of the present utility model, by defining that the distance between the rotation center of the wind wheel 340 and the center of the first laundry treating drum 310 in the up-down direction satisfies the above condition, the distance between the rotation center of the wind wheel 340 and the center of the first laundry treating drum 310 in the up-down direction is reduced, and on the one hand, the position of the wind wheel 340 can be correspondingly moved up on the basis of increasing the space below the first laundry treating drum 310, so that the installation position of the first laundry treating drum 310 is adapted to the installation position of the wind wheel 340, and on the other hand, the wind wheel 340 can be prevented from the first laundry treating drum 310, so that the size of the wind wheel 340 can be properly increased as required, which is advantageous for improving the laundry drying efficiency of the first laundry treating module 300.

Alternatively, the distance h between the rotation center of the wind wheel 340 and the center of the first laundry treating drum 310 in the up-down direction is 298mm-308mm. For example, h may be 298mm, 300mm, 303mm, 306mm, 308mm, 310mm, etc., so that the wind wheel 340, the first laundry treating drum 310 may be better laid out.

As shown in fig. 1, in a plane perpendicular to the axis of the first laundry treating drum 310, the projection of the wind wheel 340 is located in an area defined between a side wall of the cabinet assembly 150 and the projection of the first laundry treating drum 310 in the plane, according to some embodiments of the present utility model.

Specifically, a projection of one side wall of the cabinet assembly 150 on a plane perpendicular to the axis of the first laundry treating drum 310 is a straight line extending in the up-down direction, and projections of the outer circumferential wall of the first laundry treating drum 310 on a plane perpendicular to the axis of the first laundry treating drum 310 are both circular, and a triangle-like mounting area, in which the wind wheel 340 is located, may be formed between projections of both on a plane perpendicular to the axis of the first laundry treating drum 310.

Therefore, by arranging the wind wheel 340 at the above position, the space obliquely below the first laundry treating drum 310 can be effectively utilized, the space utilization rate is improved, the structural arrangement is made more compact on the basis of reducing the size of the front and rear square of the laundry treating device 1000, the overall height of the laundry treating device 1000 can be reduced, and the structural miniaturization design is facilitated.

As shown in fig. 1, in some embodiments, the distance L1 between the center of the first laundry treating drum 310 and the rotation center of the wind wheel 340 in the horizontal direction is 155mm to 165mm. For example, L1 may be 155mm, 158mm, 160mm, 162mm, 165mm, etc.

Thus, by defining the distance between the center of the first laundry treating drum 310 and the rotation center of the wind wheel 340 in the horizontal direction to satisfy the above-mentioned condition, the wind wheel 340 may avoid the side wall of the cabinet assembly 150 close to the wind wheel 340, and the wind wheel 340 may avoid the first laundry treating drum 310, so that the size of the wind wheel 340 may be properly increased as needed, which is advantageous for improving the drying efficiency of the first laundry treating module 300.

In some embodiments, as shown in FIG. 1, the center of rotation of the rotor 340 is located a distance L2 of 142mm-153mm in the horizontal direction from the side wall of the housing assembly 150 adjacent to the rotor 340. For example, L2 may be 142mm, 145mm, 148mm, 150mm, 153mm, etc.

Therefore, by limiting the distance between the rotation center of the wind wheel 340 and the side wall of the casing assembly 150, which is close to the wind wheel 340, in the horizontal direction, the wind wheel 340 can avoid the side wall of the casing assembly 150, which is close to the wind wheel 340, and the wind wheel 340 can avoid the first laundry treating drum 310, so that the size of the wind wheel 340 can be properly increased as required, which is beneficial to improving the laundry drying efficiency of the first laundry treating module 300.

In some embodiments, as shown in connection with fig. 5-7, the wind wheel 340 includes a mounting portion 341 and a plurality of blades 342, and the plurality of blades 342 are disposed on the mounting portion 341 and are spaced apart along a circumferential direction of the mounting portion 341. The plurality of blades 342 are matched to ensure the working performance of the wind wheel 340, and ensure that the wind wheel 340 can effectively drive air to circularly flow along the diversion direction of the first air channel cavity 301 in the running process, thereby achieving the purpose of drying clothes in the first clothes treating cylinder 310.

Meanwhile, the mounting portion 341 is used for supporting the plurality of blades 342, so that the positions of the plurality of blades 342 are stable, working performance of the plurality of blades 342 is guaranteed, the mounting portion 341 is further used for realizing mechanical connection between the wind wheel 340 and a driving piece, and the wind wheel 340 is conveniently driven to rotate by the driving piece, so that the wind wheel 340 is guaranteed to effectively drive air to circularly flow along the diversion direction of the first air duct cavity 301.

Alternatively, as shown in fig. 5 and 6, the plurality of blades 342 are uniformly arranged at intervals along the circumferential direction of the mounting portion 341, so that the blades 342 are uniformly distributed around the mounting portion 341, which can substantially equalize the internal stress of the entire chassis of the wind wheel 340, and further ensure the working performance of the wind wheel 340.

Alternatively, the exit angle of the vanes 342 may range from 170 to 180 and the entrance angle of the vanes 342 may range from 45 to 60. The outlet angle of the blades 342 refers to an angle formed by a tangent line of each blade 342 passing through the intersection point and a tangent line of the circumscribing circle passing through the intersection point at the intersection point of each blade 342 and the circumscribing circle intersecting each blade 342, where the angle is the outlet angle; the inlet angle of each blade 342 refers to an angle formed by a tangent line passing through the intersection point of each blade 342 and an inscribed circle passing through the intersection point at the intersection point of each blade 342 and the inscribed circle intersecting each blade 342, and the angle may be the inlet angle.

In the application, the wind wheel 340 has higher wind outlet effect and higher static pressure ratio by setting the value range of the outlet angle of the blade 342 to 170-180 degrees; through the range of the inlet angle of the blades 342 being 45-60 degrees, the loss of wind power and wind quantity in the wind wheel 340 is smaller, so that the air inlet effect of the air channel defined by the adjacent blades 342 is better, namely, the air in the first air channel cavity 301 can effectively enter between the adjacent blades 342 in the running process of the wind wheel 340, and the air guiding effect of the wind wheel 340 is ensured.

In a specific example, the exit angle of the vane 342 may be 170 °, 175 °, 180 °, etc., and the entrance angle of the vane 342 may be 45 °, 48 °, 50 °, 55 °, 60 °, etc.

In some embodiments, the outer diameter of the rotor 340 is 150mm to 160mm. When the outer diameter of the wind wheel 340 is too small, the blades 342 do not use to form a larger outlet angle, which affects the working performance of the wind wheel 340; when the outer diameter of the wind wheel 340 is excessively large, the size of the wind wheel 340 may be increased, affecting the overall assembly of the laundry treating apparatus 1000.

Therefore, the outer diameter of the wind wheel 340 is set to be 150-160 mm, so that the blades 342 have a larger outlet angle, the bending degree of the blades 342 is larger, the system air quantity is effectively improved, the outer diameter size of the wind wheel 340 can be reduced, the diameter of the wind wheel 340 is reduced, the whole size of the clothes treatment device 1000 is reduced, the space utilization rate of the clothes treatment device 1000 can be improved, the material consumption of the wind wheel 340 is reduced, and the manufacturing cost of the wind wheel 340 is reduced.

In particular examples, the outer diameter of the rotor 340 may be 150mm, 152mm, 157mm, 160mm, or the like.

It is also worth noting that, in the application, the outlet angle of the blade 342 is set to 170-180 degrees, the inlet angle of the blade 342 is set to 45-60 degrees, and the outer diameter of the wind wheel 340 is set to 150-160 mm to be matched with the outlet angle and the inlet angle of the blade 342, so that the flow field in the wind wheel 340 and the first air channel cavity at the outlet side of the wind wheel 340 is better in compatibility, the connection and fusion effects of the flow field are improved, the air flows in the wind wheel 340 and the first air channel cavity are smoother, vortex and backflow phenomena in the first air channel cavity are effectively restrained, the high efficiency of the wind wheel 340 is maintained, and the aerodynamic noise is reduced.

Alternatively, the ratio of the diameter of the inscribed circle of the plurality of blades 342 to the outer diameter of the wind wheel 340 is 0.75-0.85. On the one hand, the wind wheel 340 has more sufficient air suction area, on the other hand, the distribution positions of the blades 342 are ensured, the flow resistance at the inlet of the air channel between the adjacent blades 342 is ensured not to be too large, the flow and the pressure head loss in the wind wheel 340 are reduced, meanwhile, the distribution of the blades 342 at the inscribed circle position is ensured not to be too sparse, and the kinetic energy loss and the noise problem caused by shearing air flow are prevented.

In a specific example, the ratio of the diameter of the inscribed circle of the plurality of blades 342 to the outer diameter of the wind wheel 340 is 0.75, 0.792, 0.8, 0.82, or 0.85, etc.

Optionally, the number of the blades 342 is 35-45, so that the air duct flow guiding efficiency between the adjacent blades 342 is higher, the flow and the pressure head loss inside the wind wheel 340 are reduced, and the air flow can be kept smooth when flowing between the adjacent blades 342, so that the shearing flow condition in the first air duct cavity can be further improved, the basically uniform flow field inside the first air duct cavity is realized, the high efficiency of the wind wheel 340 is maintained, and the aerodynamic noise at the blades 342 and in the first air duct cavity is reduced.

In a specific example, the number of blades 342 is 35, 38, 41, 45, or the like.

Alternatively, the blades 342 may have a thickness of 1mm to 2mm. If the thickness of the blade 342 is too thin, the structural strength of the blade 342 is poor, the blade 342 is easily torn, and the service life of the blade 342 is affected; if the thickness of the blades 342 is too thick, the weight of the wind wheel 340 may be increased, not only the manufacturing cost of the wind wheel 340 may be increased, but also the flow area of the wind channel between adjacent blades 342 may be reduced.

Therefore, the thickness of the vane 342 is controlled within the range of 1mm to 2mm, and the structural strength and the airflow area can be simultaneously required.

In particular embodiments, the thickness of the blade 342 is 1mm, 1.25mm, 1.5mm, 1.75mm, 2mm, or the like

In summary, the present application improves the system air volume by adjusting the outlet angle, inlet angle and blade shape of the wind wheel 340, so that the wind wheel 340 of the present application has the advantages of small size, large air volume, etc.

It should be noted that, at present, in order to reduce the difficulty of installing the laundry treatment apparatus 1000, the dimension of the laundry treatment apparatus 1000 in the height direction is generally reduced, which results in a limited space dimension of the first air channel cavity 301 of the first laundry treatment module 300, and further results in a larger resistance of air in the flowing process, and brings serious air volume attenuation problem, while the wind wheel 340 of the present application has the advantages of small dimension, large air volume, etc., so that the wind wheel 340 of the present application can be effectively applied in the narrow first air channel cavity 301, and the air can maintain a large air volume in the narrow first air channel cavity 301, so as to improve the working performance of the first laundry treatment module 300.

It should be further noted that, because the bending degree of the blade 342 is larger, the residual burrs in the first air channel cavity 301 are more likely to be hung on the blade 342, so the application sets the plurality of filtering pieces 321 at the upstream of the wind wheel 340, so as to utilize the plurality of filtering pieces 321 to filter the air flowing to the wind wheel 340, and prevent the burrs from flowing to the wind wheel 340, so as to prevent the burrs from being hung on the blade 342 of the wind wheel 340, thereby ensuring the working performance of the wind wheel 340, and further ensuring that the air can circularly flow in the narrow first air channel cavity 301 and maintain large air volume flow.

That is, the laundry treating apparatus 1000 of the present application has advantages of large air volume and low lint residue at the same time.

As shown in fig. 2 to 4, the first laundry treating module 300 further includes a rear plate 370 and a duct case 381, the rear end of the first laundry treating drum 310 is rotatably fitted to one side in the thickness direction of the rear plate 370, the duct case 381 and the other side in the thickness direction of the rear plate 370 define a first duct chamber 301, the first duct chamber 301 communicates with the inner cavity of the first laundry treating drum 310, and a rotatable wind wheel 340 is provided in the first duct chamber 301.

The wind wheel 340 operates to drive air to flow along the direction of flow of the first air channel cavity 301, and when the air flows through the first laundry treating drum 310, the air is used to contact with wet laundry in the first laundry treating drum 310 and take away moisture on the wet laundry, so as to implement drying treatment of the laundry.

As can be seen from the above structure, the rear plate 370 and the air duct case 381 are disposed at the rear of the first laundry treating drum 310 to define the first air duct chamber 301, and the wind wheel 340 is disposed in the first air duct chamber 301, so that the wind wheel 340 can be used to drive air to flow along the direction of flow of the first air duct chamber 301, so as to deliver relatively dry air to the inner cavity of the first laundry treating drum 310, thereby achieving the purpose of drying laundry.

As shown in fig. 8-16, in some embodiments, the first air duct chamber 301 includes a main air duct 3011 and an air intake chamber 3012, the main air duct 3011 is disposed opposite to the first laundry treating drum 310, and the main air duct 3011 communicates with the air intake chamber 3012 and an inner cavity of the first laundry treating drum 310, a wind wheel 340 is rotatably disposed in the air intake chamber 3012, a volute tongue 3811 is disposed on an inner wall of the air duct case 381, and the volute tongue 3811 is disposed between the main air duct 3011 and the air intake chamber 3012.

When the wind wheel 340 works, air can be driven into the air inlet cavity 3012, and under the driving of the wind wheel 340 and the action of the volute tongue 3811, the air in the air inlet cavity 3012 flows towards the main air duct 3011 and then enters the inner cavity of the first laundry treating drum 310 from the bottom of the first laundry treating drum 310. By providing the volute tongue 3811 on the inner wall of the air duct case 381, air can be prevented from circulating in the air inlet chamber 3012 and not entering the main air duct 3011, and air can be allowed to enter the inner chamber of the first laundry treating drum 310 from the bottom of the first laundry treating drum 310, so that the first laundry treating module 300 can work normally.
