Example 1:

as shown in fig. 1 to 3, an embodiment of the present utility model provides a laundry treating apparatus 1, comprising: the drying module 3 and the roller 2 are provided with at least one roller air outlet 202 and a roller air inlet 203, and the roller air outlet 202 and the roller air inlet 203 are respectively communicated with the drying module 3 in an air flow way to form a drying air flow passage. The drying module 3 is disposed above the drum, and includes a first air outlet 32 and a first air inlet 33, and is communicated with the air outlet of the drum through the first air inlet 33, and is communicated with the air inlet of the drum through the first air outlet 32. Based on this, the drying module 3 forms a circulation path with the drum 2, thereby achieving drying of the hot and humid air circulating therein. In the drying mode, the drying air flow is guided from the drum 2 to the drying module 3 through the first air inlet 33 of the drying module 3, the drying module 3 dehumidifies and heats the drying air flow from the drum 2, and then the drying air flow is guided back to the drum 2 through the first air outlet 32 of the drying module 3, so that the circulation is repeated, thereby drying the laundry.

As shown in fig. 3, the drying module 3 includes a first drying module housing 310 and a second drying module housing 320, and a moisture absorbing and discharging member 300. The moisture absorbing and removing member 300 may be made of a material having good moisture absorbing and desorbing properties, for example, zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X type) molecular sieve. The absorbent and dehumidifying member 300 may also be provided in various shapes, such as a rotary disk provided in a circular shape, a strip-shaped absorbent belt, a container having an opening of various shapes, or the like. In addition, when the moisture absorbing and discharging member 300 is a turntable, the drying module 3 may further include a driving assembly (not shown), and the driving assembly may include a motor, and the motor may drive the turntable to rotate.

The first drying module housing 310 has a first space, the second drying module housing 320 has a second space, and the moisture absorbing and discharging member 300 is disposed between the first drying module housing and the second drying module housing. A gap is formed between the first surface 3001 of the moisture absorbing and discharging member and a portion of the top wall of the first drying module housing 310 to form a first air flow channel; a gap is formed between the second surface 3002 of the moisture absorbing and discharging member and a portion of the bottom plate of the second drying module case 320 to form a second air flow channel; the second air flow path, the moisture absorbing and discharging member 300, and the first air flow path form an air flow path.

The second drying module case 320 includes a second drying module case bottom plate 3201 and a circumferential side wall protruding from the bottom plate, and the formed recess is a second space. Two second partitions 321 are radially disposed along the second drying module case 320 in the second space to partition the second space into a dehumidifying region and a regeneration region; therefore, the moisture absorbing and discharging member 300 is beneficial to continuously absorbing and desorbing moisture through the dehumidifying region and the regenerating region in the rotating process, so that the moisture absorbing and discharging member 300 has good water absorbing capacity all the time, and the moisture absorbing efficiency and effect are improved. Preferably, the two second dividers 321 are arranged in a V-shape, and the dehumidifying region and the regenerating region are generally fan-shaped.

The first drying module housing 310 includes a first drying module housing top wall 3101 and a circumferential side wall, and the recess formed is a first space. Two first spacers 311 are correspondingly disposed along the radial direction of the first drying module housing at positions corresponding to the two second spacers 321 in the first space to divide the first space into a dehumidifying area and a regeneration module mounting area; the first drying module housing 310 is disposed opposite to the recess structure of the second drying module housing 320, and when the first drying module housing 310 is connected with the second drying module housing 320, the first space and the second space form a receiving cavity of the moisture absorbing and draining member 300, and the receiving cavity of the moisture absorbing and draining member 300 has an air flow passing therethrough, so that the first drying module housing 310 and the second drying module housing 320 may be in sealing connection. The moisture absorbing and discharging member 300 is located between the second partition 311 and the first partition 321, so that in order to prevent the drying air flow and the regeneration air flow discharged from the drum from channeling each other, the dynamic sealing effect can be formed between the second partition 321 and the first partition 311 and the moisture absorbing and discharging member 300, and thus the moisture absorbing and discharging member 300 is beneficial to continuously absorbing moisture and dehydrating and drying through the dehumidification area and the regeneration area in the rotating process, so that the moisture absorbing and discharging member 300 has good water absorbing capability all the time, and the moisture absorbing efficiency and effect are improved. Preferably, the two first partitions 311 are arranged in a V-shape, and the dehumidifying area and the regeneration module mounting area are substantially fan-shaped.

The partition referred to herein means each individual partition disposed from the circumferential side wall of the first drying module housing 310 or the second drying module housing 320 to the radial connection between the central positions of the housings. The at least two first spacers 311 and the at least two second spacers 321 may be integrally formed, or may be separately manufactured and installed in a manner that does not affect the definition of the spacers.

As shown in fig. 3 to 5, a first air inflow opening 301 is provided in the second space, a first air outflow opening 304 is provided in the first space, and the drying air flow passes through the first air inflow opening 301, sequentially passes through the second space, the moisture absorbing and discharging member 300, and the first space, and finally passes through the first air outflow opening 304.

Fig. 6 (a) is a schematic cross-sectional view of a dehumidifying area when a drying module is horizontally disposed according to an embodiment of the present utility model. The schematic drawing is a schematic illustration of the cross-sectional structure, and is merely for illustrating the structure of the dehumidification region, and does not represent the actual shape.

As shown in fig. 6 (a), the second drying module case 320 has a second space 3202, and in a dehumidifying region of the second space 3202, the second drying module case bottom plate 3201 has a distance d in a vertical direction to the second surface 3002 of the moisture absorbing and discharging member, and in the second space 3202, the distance d near the first air inflow port 301 is different in size from at least a part of the distance d at other positions apart from the first air inflow port 301 as seen in an overall flow direction of the drying air flow in the second space 3202.

It is understood that the "overall flow direction" of the drying air flow in the second space 3202 refers to a direction in which the drying air flow formed by regarding the air flow flowing through as a whole in the space between the second surface 3002 of the moisture absorbing and removing member and the bottom plate 3201 of the second drying module housing generally flows, i.e., generally flows from the first air flow inlet 301 to the first air flow outlet 304, as shown by the arrow in fig. 5. It should be noted that, in the second space 3202, a flow direction of a small portion of the drying air flow is different from the overall flow direction, for example, the drying air flow passes through the moisture absorbing and discharging member 300 from the second space 3202 to the first space 3102, and the portion of the drying air flow does not cause the "overall flow direction" to change.

Through this setting, can make the gas circuit shape convergence that the stoving air current flows through to can effectively compensate the pressure loss of air current under the circumstances that the moisture in the stoving air current is adsorbed by lasting and leads to the stoving air current density to reduce.

Preferably, the distance d at the first air flow inlet 301 is larger than the distance d at least partially away from the first air flow inlet 301 in the dehumidifying region, as seen in the overall flow direction along the drying air flow in the second space 3202.

Preferably, the distance d becomes gradually smaller in the dehumidifying region from the first gas inflow port 301 toward a direction gradually away from the first gas inflow port 301 as seen in the overall flow direction of the drying gas flow in the second space 3202.

Preferably, the second surface 3002 of the moisture absorbing and removing member is substantially a plane, and an included angle between the plane of the second space 3202, the second drying module housing base plate 3201 and the plane of the second surface 3002 of the moisture absorbing and removing member is in a range of 0 ° to 45 °. Preferably, at least a portion of the second drying module housing base plate 3201 is disposed at an angle in the range of 5 ° to 15 ° to the plane of the second surface 3002 of the moisture absorbing and removing member.

Preferably, the distance is between 15-50mm in the vicinity of the first gas flow inlet 301 of the second space 3202; the distance is between 8-40mm furthest from the first gas flow inlet 301. Preferably, the distance is between 20-40mm at the first gas flow inlet 301 of the second space 3202; the distance is between 10-26mm furthest from the first gas flow inlet 301. The farthest point here refers to the position at the end of the moisture absorption region of the second space 3202, i.e., the boundary position between the moisture absorption region and the regeneration region, along the entire flow direction of the drying air flow in the second space 3202.

Through the above preferred embodiments, the shape of the air path through which the drying air flows can be converged, so that the pressure loss of the air flow can be effectively compensated, the pressure and the flow speed of the air flow can be kept stable, and the air flow can be fully contacted with the moisture absorption and removal component 300 under the condition that the density of the drying air flow is reduced due to continuous absorption of moisture in the drying air flow. The technical solution of the embodiment of the present utility model can enable the drying air flow to achieve a relatively uniform adsorption effect at each position of the moisture absorption and removal member 300.

In addition, as shown in fig. 6 (b), the first drying module housing 310, the moisture-absorbing and moisture-discharging member 300 and the second drying module housing 320 may be further disposed in a vertical manner, and the structure and the drying principle implemented by the same corresponds to the first drying module housing 310, the moisture-absorbing and moisture-discharging member 300 and the second drying module housing 320 disposed horizontally in fig. 6 (a), which are not described herein again.

It should be noted that, although the first drying module housing top wall 3101 and the second drying module housing bottom plate 3201 may be gradually inclined and extended after a distance from the first air inflow opening 301 as shown in fig. 6 (a) and 6 (b), in other embodiments, the first drying module housing top wall 3101 and/or the second drying module housing bottom plate 3201 may be directly inclined and extended near the first air inflow opening 301.

Further, although shown in fig. 6 (a) and 6 (b), the first and second drying module housings 310 and 320 each have a bottom plate or a top wall gradually inclined and extended. In practice, however, only the first drying module housing top wall 3101 of the first drying module housing 310 may be gradually inclined and extended, or only the second drying module housing bottom plate 3201 of the second drying module housing 320 may be gradually inclined and extended.

The regeneration module 31 may include a heating assembly for heating the regeneration air flow, and the hygroscopic and dehumidifying member 300 passes through the dehumidifying and regenerating regions during rotation, thereby continuously performing a cycle process of adsorbing and desorbing moisture. Preferably, the heating assembly may employ an element having a heating function, such as a heating wire, a PTC heater, or the like.

Specifically, one or more flow splitters 322 can be provided. When the flow dividing member 322 is two or more, it may be disposed in parallel so as to divide the space into a plurality of flow dividing regions. By arranging the splitter 322 on the second drying module housing bottom plate 3201, the drying airflow flowing into the moisture absorption area of the second space 3202 can be split, one part of the drying airflow enters the area close to the center of the circle, and the other part of the drying airflow enters the area close to the periphery of the moisture absorption and drainage member 300, so that the drying airflow flowing into the circulation path is more dispersed and uniform, the airflow and the moisture absorption and drainage member 300 can be in contact with each other in a larger area, and the moisture absorption efficiency of the moisture absorption and drainage member 300 is improved.

In one embodiment as shown in fig. 7 (a), the first drying module housing 320, the moisture absorbing and discharging member 300, and the second drying module housing 310 are disposed in a horizontal manner, and a gap is formed between the first surface 3001 of the moisture absorbing and discharging member 300 and at least a portion of the second drying module housing 310 in the regeneration region to form a third space 3302; the second face 2002 of the moisture absorbing and discharging member 300 has a gap with at least a portion of the first drying module case 320 to form a fourth space 3402.

In one embodiment as shown in fig. 7 (b), the first drying module housing 320, the moisture absorbing and discharging member 300, and the second drying module housing 310 may be further disposed in a vertical manner. By this vertical arrangement, the distances between the corresponding surfaces of the first drying module housing top wall 3101, the second drying module housing bottom plate 3201 and the moisture absorbing and discharging members are kept constant in the regeneration area as well.

Accordingly, the first drying module housing 310 includes a first drying module housing top wall 3101 and a circumferential side wall, and the recess formed is a first space. At positions corresponding to the three second spacers 321 in the first space 3102, three first spacers 311 are correspondingly disposed along the radial direction of the first drying module housing 310 to divide the first drying module housing 310 into a dehumidifying region, a cooling region, and a regeneration module mounting region (not shown). The recess structures of the first drying module housing 310 and the second drying module housing 320 are disposed opposite to each other, so that the first drying module housing 310 and the second drying module housing 320 are in sealing connection. The moisture absorbing and discharging member 300 is used to absorb moisture of the circulating air flow in the moisture absorbing region, cool the moisture absorbing and discharging member 300 in the cool down region, and discharge the moisture absorbed in the moisture absorbing region through the moisture discharging flow of the regeneration region, respectively, during the rotation.

In particular, the second space 3202 has a first air inflow port 301, and the drying air flow passes through the first air inflow port 301 and sequentially passes through the second space 3202, the moisture absorbing and discharging member 300, and the first space 3102; as seen in the overall flow direction of the drying air flow in the second space 3202, in the hygroscopic region, at least a portion of the position away from the first air flow inlet 301 has an area of a different cross section than at the first air flow inlet 301.

It is understood that the "overall flow direction" of the drying air flow in the second space 3202 refers to a direction in which the drying air flow formed by regarding the air flow flowing through as a whole in the space between the second surface 3002 of the moisture absorption and moisture removal member and the bottom plate 3201 of the second drying module housing, that is, the direction generally flowing from the first air flow inlet 301 to the first air flow outlet 304, as shown by the arrow in fig. 5. It should be noted that, in the second space 3202, a flow direction of a small portion of the drying air flow is different from the overall flow direction, for example, the drying air flow passes through the moisture absorbing and discharging member 300 from the second space 3202 to the first space 3102, and the portion of the drying air flow does not cause the "overall flow direction" to change.

Preferably, the cross-sectional area at the first gas flow inlet 301 is larger than the cross-sectional area at least partially distant from the first gas flow inlet 301 in the hygroscopic region, as seen in the overall flow direction along the drying gas flow in the second space 3202.

Preferably, the cross-sectional area is gradually smaller in the moisture absorption region from the first gas flow inlet 301 toward a direction gradually away from the first gas flow inlet 301, as seen in the overall flow direction of the drying gas flow in the second space.

Preferably, at least a portion of the second drying module housing bottom plate 3201 is gradually inclined upward and extended in the dehumidifying region as viewed in the overall flow direction along the drying air flow in the second space 3202, so that the second space 3202 has a substantially right trapezoid shape in cross section in the radial direction of the moisture absorption and discharge member 300.

It is understood that the "cross section" referred to herein refers to a section in a vertical direction of a space formed between the second drying module housing bottom plate 3201, the side walls and the corresponding surfaces of the moisture absorption and discharge member 300, as seen in the overall flow direction of the second space 3202 along the drying air flow.

In summary, the present utility model provides a laundry machine, in which the moisture absorption area in the second space is configured to be converged in the shape of the air path flowing through the air flow path, so that the pressure loss of the air flow can be effectively compensated for, the pressure and the flow rate of the air flow can be kept stable, and the air flow can be fully contacted with the moisture absorption and removal member, in the case that the density of the drying air flow is reduced due to continuous adsorption of moisture in the drying air flow. Therefore, the technical scheme of the utility model can enable the moisture absorption and removal component to realize better absorption effect on the drying airflow flowing in the moisture absorption and removal component.

In addition, by maintaining the distance between the bottom plate of the second drying module case 320 located at the regeneration region of the second space and the corresponding surface of the moisture absorbing and discharging member 300 constant, the flow height of the drying air flow in the regeneration region of the drying module is maintained constant, so that the heat received by each part of the moisture absorbing and discharging member rotating through the regeneration region is uniform, substantially the same regeneration effect is achieved, and the phenomenon of local overheating of the regeneration region is avoided.

In addition, the bottom plate of the second drying module case 320 in the moisture absorption region is further provided with a flow dividing member along the flowing direction of the drying air flow, so that the drying air flow flowing into the moisture absorption region can be divided, one part of the drying air flow enters the region close to the center of the circle, and the other part of the drying air flow enters the region close to the periphery of the moisture absorption and moisture removal member, so that the drying air flow flowing into the air flow channel is more dispersed and more uniform, and can be contacted with the moisture absorption and moisture removal member more uniformly, thereby improving the moisture absorption efficiency of the moisture absorption and moisture removal member.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.

In addition, the technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be regarded as the scope of the description. In other words, the non-conflicting portions of the above embodiments may be replaced or supplemented with each other to form a new embodiment.
