Description

Clothing processing equipment

The present invention relates to the field of household appliances, and in particular to a clothing processing device.

Driven by factors such as people's increasing pursuit of a healthy and high-quality life and the ever-accelerating pace of life for urban residents, washer-dryers have emerged and are deeply loved by consumers. Washer-dryers are particularly suitable for families in the south during the rainy season, families in the north where poor air quality makes it difficult to dry clothes outdoors, and users who want clothes to be washed and worn immediately or who seek more fluffy and comfortable clothes.

Most existing clothing drying devices use an evaporator to heat and absorb moisture from the humid air in the washer/dryer drum. This high-temperature air is then re-entered into the drum, evaporating the moisture from the clothing. However, the evaporator maintains a consistent temperature throughout the entire system, and its ability to absorb moisture decreases during the evaporation process. This results in low moisture absorption efficiency, long drying times, and high power consumption. Alternatively, some systems use condensate spraying or direct condenser dehumidification of the humid airflow. However, these treated airflows still contain a high percentage of moisture, and recycling requires the airflow to undergo a cycle of "heating, cooling, dehumidification, and reheating," resulting in low dehumidification efficiency and high power consumption.

Therefore, it is urgent to design a clothes processing device that overcomes the above-mentioned defects, can make power consumption reasonable, and has better drying effect.

This application claims priority to Chinese patent application No. 202310108656.4, filed on January 17, 2023, the entire contents of which are incorporated herein by reference.

(3) Beneficial effects

The above-mentioned technical solution of the present invention has the following beneficial technical effects: by setting the partial space formed by the second drying module shell and the moisture absorption and discharge component as: there is a distance in the vertical direction from the bottom plate of the second drying module shell to the corresponding surface of the moisture absorption and discharge component, in the dehumidification area, the distance near the first air flow inlet is different from at least part of the distance at other positions far from the first air flow inlet, which can make the shape of the air path converge in the direction of gas flow, so that when the moisture in the drying air flow is continuously adsorbed and the density of the drying air flow decreases, the pressure loss of the air flow can be effectively compensated, so that the pressure and flow rate of the air flow remain stable and can fully contact the moisture absorption and discharge component. Therefore, the technical solution of the present invention can enable the moisture absorption and dehumidification component to achieve a better adsorption effect on the drying airflow flowing therein.

To further clarify the objectives, technical solutions, and advantages of the embodiments of the present invention, the following provides a clear and complete description of the technical solutions of the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, but not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

In the description of this specification, reference to the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any one or more embodiments or examples in an appropriate manner. In addition, different embodiments or examples described in this specification and features of different embodiments or examples can be combined and combined by a person skilled in the art, unless they are mutually inconsistent.

As used herein, the term "regeneration" refers to the restoration of a relatively dry object to a relatively dry state by at least partially dehumidifying it after absorbing moisture. The terms "upstream" and "downstream" are used to indicate the relative positions of a second element encountered by airflow after passing through a first element in a flow path originating at the system inlet, with the first element being "upstream" of the second element and the second element being "downstream" of the first element.

Example 1:

As shown in Figures 1 to 3, an embodiment of the present invention provides a clothing processing apparatus 1, comprising a drying module 3 and a drum 2. Drum 2 has at least one drum air outlet 202 and one drum air inlet 203. The drum air outlet 202 and the drum air inlet 203 are respectively in airflow communication with the drying module 3, forming a drying airflow path. The drying module 3 is disposed above the drum 2 and includes a first air outlet 32 and a first air inlet 33. The drying module 3 is in communication with the drum air outlet 202 via the first air inlet 33, and with the drum air inlet 203 via the first air outlet 32. Consequently, the drying module 3 and the drum 2 form a circulation path, thereby drying the hot and humid air circulating therein. In the drying mode, the drying airflow 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 airflow from the drum 2, and then guides the drying airflow back to the drum 2 through the first air outlet 32 of the drying module 3. This cycle is repeated to dry the clothes.

As shown in Figure 3, the drying module 3 comprises a first drying module housing 310, a second drying module housing 320, and a moisture absorption and desorption component 300. The moisture absorption and desorption component 300 can be made of a material with excellent moisture absorption and desorption properties, such as zeolite, lithium chloride, silica gel, modified silica gel, or 13X (sodium X-type) molecular sieve. The moisture absorption and desorption component 300 can also be configured in various shapes, such as a circular rotating disc, a strip-shaped moisture absorption belt, or a container with openings of various shapes. In addition, when the moisture absorption and discharge component 300 uses a rotary disk, the drying module 3 may further include a driving element (not shown in the figure), which may include a motor that can drive the rotary disk to rotate.

It is understood that the pore diameter of the moisture absorption and drainage component 300 generally represents the diameter of the component's pore structure. When the pore shape is regular, such as rectangular, triangular, circular, elliptical, or corrugated, the pore diameter can be the side length of the rectangle, the height of the triangle, the diameter of the circle or elliptical, the wave height of the corrugated, etc. In some embodiments, the pore diameter can be represented by the wave height in the moisture absorption and drainage component 300, such as the wave height of the corrugated; the pore diameter can also be represented by the diameter of the circumscribed circle of the moisture absorption and drainage component 300.

4 and 5 , the first drying module housing 310 has a first space, the second drying module housing 320 has a second space, and the moisture absorption and discharge component 300 is disposed between the first drying module housing 310 and the second drying module housing 320. A gap is formed between the first surface 3001 of the moisture absorption and discharge component 300 and a portion of the top wall of the first drying module housing 310 to form a first airflow channel. A gap is formed between the second surface 3002 of the moisture absorption and discharge component 300 and a portion of the bottom plate of the second drying module housing 320 to form a second airflow channel. The second airflow channel, the moisture absorption and discharge component 300, and the first airflow channel together form an airflow passage.

The second drying module housing 320 comprises a second drying module bottom plate 3201 and a peripheral sidewall protruding from the bottom plate, forming a recessed portion serving as a second space. Within the second space, two second dividers 321 are radially arranged along the second drying module housing 320 to separate the second space into a dehumidification zone and a regeneration zone. This facilitates the rotation of the moisture absorption and dehumidification component 300, allowing it to continuously absorb and desorb moisture, thereby maintaining a high water absorption capacity and improving moisture absorption efficiency and effectiveness. Preferably, the two second dividers 321 are arranged in a V-shape, with the dehumidification and regeneration zones being generally fan-shaped.

4 and 5 , the first drying module housing 310 includes a first drying module housing top wall 3101 and circumferential side walls, and the recessed portion formed therein is a first space. At positions corresponding to the two second partitions 321 in the first space, two first partitions 311 are radially arranged along the first drying module shell 310 to divide the first space into a dehumidification area and a regeneration module installation area; the recessed structures of the first drying module shell 310 and the second drying module shell 320 are arranged opposite to each other, and when the first drying module shell 310 and the second drying module shell 320 are matched and connected, the first space and the second space can form a storage chamber for the moisture absorption and discharge component 300. Since air flows through the storage chamber of the moisture absorption and discharge component 300, the first drying module shell 310 and the second drying module shell 320 can be set to be a sealed connection. The moisture absorption and dehumidification component 300 is located between the second partition 321 and the first partition 311. To prevent the drying airflow and the regeneration airflow discharged from the drum 2 from intercommunication, the second partition 321 and the first partition 311 form a dynamic seal with the moisture absorption and dehumidification component 300. This facilitates the moisture absorption and dehumidification component 300 to continuously absorb water and dehydrate and dry the water as it rotates, passing through the dehumidification and regeneration zones. This ensures that the moisture absorption and dehumidification component 300 maintains a high water absorption capacity, thereby improving the efficiency and effectiveness of moisture absorption. Preferably, the two first partitions 311 are arranged in a V-shape, and the dehumidification and regeneration module installation areas are generally fan-shaped.

It should be noted that the dividers referred to herein are individual dividers radially extending from the circumferential sidewalls of the first drying module housing 310 or the second drying module housing 320 toward the center of the housing. The at least two first dividers 311 and the at least two second dividers 321 can be integrally formed or manufactured and installed separately; the manufacturing method does not affect the definition of the dividers.

As shown in Figures 3 to 5, a first air inlet 301 is provided in the second space, and a first air outlet 304 is provided in the first space. The drying air passes through the first air inlet 301 and passes through the second space, the moisture absorption and exhaust component 300 and the first space in sequence, and finally flows out through the first air outlet 304.

Figure 6a is a schematic cross-sectional view of the dehumidification zone when the drying module is horizontally arranged according to an embodiment of the present invention. It should be noted that this schematic view is a schematic illustration of the cross-sectional structure and is only for the purpose of illustrating the structure of the dehumidification zone and does not represent the actual shape.

As shown in Figure 6a, the second drying module shell 320 has a second space 3202. In the dehumidification area of the second space 3202, there is a distance d in the vertical direction from the bottom plate 3201 of the second drying module shell to the second surface 3002 of the moisture absorption and exhaust component 300. From the perspective of the overall flow direction of the drying airflow in the second space 3202, in the second space 3202, the distance d near the first air inlet 301 is different from at least part of the distance d at other positions far away from the first air inlet 301.

It should be understood that the "overall flow direction" of the drying airflow in the second space 3202 refers to the general direction of the drying airflow formed by the airflow flowing through the space between the second surface 3002 of the moisture absorption and exhaust component 300 and the bottom plate 3201 of the second drying module housing as a whole, that is, the direction generally from the first airflow inlet 301 to the first airflow outlet 304, as indicated by the arrow in Figure 5. It should be noted that within the second space 3202, a small portion of the drying airflow may flow in a direction different from the overall flow direction. For example, when the drying airflow passes from the second space 3202 through the moisture absorption and exhaust component 300 to the first space 3102, this portion of the drying airflow does not cause the "overall flow direction" to change.

This arrangement can narrow the shape of the air path through which the drying air flows, thereby effectively compensating for the pressure loss of the air flow when the moisture in the drying air flow is continuously adsorbed, resulting in a decrease in the drying air flow density.

Preferably, viewed along the overall flow direction of the drying airflow in the second space 3202 , in the dehumidification area, the distance d at the first airflow inlet 301 is greater than the distance d at least partially away from the first airflow inlet 301 .

Preferably, viewed from the overall flow direction of the drying airflow in the second space 3202, in the dehumidification area, the distance d gradually decreases in the direction from the first airflow inlet 301 to gradually away from the first airflow inlet 301.

Preferably, the second surface 3002 of the moisture absorption and discharge component 300 is substantially planar. Within the second space 3202, the plane of the second drying module housing bottom plate 3201 and the plane of the second surface 3002 of the moisture absorption and discharge component 300 form an angle in the range of 0° to 45°. Preferably, the plane of at least a portion of the second drying module housing bottom plate 3201 and the plane of the second surface 3002 of the moisture absorption and discharge component 300 form an angle in the range of 5° to 15°.

Preferably, near the first air inlet 301 of the second space 3202, the distance is between 15-50 mm; at the farthest point from the first air inlet 301, the distance is between 8-40 mm. Preferably, at the first air inlet 301 of the second space 3202, the distance is between 20-40 mm; at the farthest point from the first air inlet 301, the distance is between 10-26 mm. The farthest point referred to herein refers to the end of the dehumidification zone of the second space 3202, i.e., the boundary between the dehumidification zone and the regeneration zone, along the overall flow direction of the drying airflow in the second space 3202.

Through the above preferred implementation, the shape of the air path through which the drying air flows can be converged. This effectively compensates for air pressure loss when moisture in the drying air is continuously adsorbed, resulting in a decrease in drying air density. This allows the airflow pressure and flow rate to remain stable, ensuring sufficient contact with the moisture absorption and dehumidification component 300. The technical solution of this embodiment of the present invention enables the drying airflow to achieve a relatively uniform adsorption effect at all locations within the moisture absorption and dehumidification component 300.

In addition, as shown in Figure 6b, the first drying module shell 310, the moisture absorption and exhaust component 300 and the second drying module shell 320 can also be arranged vertically. Their structure and the drying principle realized correspond one-to-one to the first drying module shell 310, the moisture absorption and exhaust component 300 and the second drying module shell 320 arranged horizontally in Figure 6a, and will not be repeated here.

It should be noted that, although as shown in Figures 6a and 6b, the first drying module shell top wall 3101 and the second drying module shell bottom plate 3201 may gradually tilt and extend after a certain distance from the first air inlet 301, in other embodiments, the first drying module shell top wall 3101 and/or the second drying module shell bottom plate 3201 may be directly tilted and extended near the first air inlet 301.

Furthermore, although both the first drying module housing 310 and the second drying module housing 320 have gradually inclined and extended bottom plates or top walls as shown in FIG6a and FIG6b , in practice, only the first drying module housing 310 may have a gradually inclined and extended first drying module housing top wall 3101, or only the second drying module housing 320 may have a gradually inclined and extended second drying module housing bottom plate 3201.

In addition, as shown in FIG3 , the drying module 3 preferably further includes a regeneration module 31, which is coupled to the first drying module housing 310. The first drying module housing 310 is formed with a generally fan-shaped regeneration module housing. The regeneration module 31 is mounted in the regeneration module housing and is located above the moisture absorption and dehumidification component 300. The regeneration module 31 is used, for example, to heat the regeneration airflow to desorb moisture absorbed by the moisture absorption and dehumidification component 300. The regeneration module 31 may include a heating component for heating the regeneration airflow. During the rotation of the moisture absorption and dehumidification component 300, it passes through the dehumidification zone and the regeneration zone, thereby continuously performing a cycle of adsorbing and desorbing moisture. Preferably, the heating component can adopt a heating element such as a heating wire, a PTC heater, etc.

Preferably, the area of the dehumidification zone of the second space 3202 is greater than or equal to the area of the regeneration zone. Preferably, the ratio of the area of the dehumidification zone to the area of the regeneration zone is approximately 5:1 to 1:1.

Preferably, a circulation fan (not shown) is further provided between the first air inlet 33 of the drying module 3 and the drum air outlet 202 to accelerate the flow of the circulating moisture-absorbing airflow. Furthermore, preferably, the speed of the circulation fan can be adjusted according to the drying process. Even more preferably, the speed of the circulation fan can be adjusted according to the airflow temperature at the first air outlet 32 of the drying module 3.

As shown in Figure 1, the drying module 3, the first air inlet 33 and the first air outlet 32 are all located at the top of the clothing processing device. This layout can make full use of the upper space of the drum 2, making the overall layout of the clothing processing device 1 very compact.

Preferably, as shown in Figure 5 , a diverter 322 is further provided on the second drying module housing 320 in the dehumidification zone of the second space 3202, along the direction of the drying airflow. The diverter 322 is configured to divide the drying airflow flowing in the dehumidification zone. Specifically, one or more diverters 322 may be provided. When there are two or more diverters 322, they may be offset to divide the space into multiple diversion zones. By arranging a diverter 322 on the bottom plate 3201 of the second drying module shell, the drying airflow flowing into the dehumidification area of the second space 3202 can be diverted, with one part entering the area close to the center of the circle and the other part entering the area close to the periphery of the moisture absorption and exhaust component 300, so that the drying airflow flowing into the circulation path is more dispersed and uniform, and the airflow can contact the moisture absorption and exhaust component 300 over a larger area, thereby improving the moisture absorption efficiency of the moisture absorption and exhaust component 300.

In an embodiment as shown in Figure 7a, the first drying module shell 310, the moisture absorption and exhaust component 300 and the second drying module shell 320 are arranged in a horizontal manner. In the regeneration area, there is a gap between the first surface 3001 of the moisture absorption and exhaust component 300 and at least a portion of the first drying module shell 310 to form a third space 3302; there is a gap between the second surface 3002 of the moisture absorption and exhaust component 300 and at least a portion of the second drying module shell 320 to form a fourth space 3402.

In the regeneration area, the top wall 3101 of the first drying module shell is parallel or approximately parallel to the first surface 3001 of the moisture absorption and exhaust component 300 along the direction of airflow, and the bottom plate 3201 of the second drying module shell is parallel or approximately parallel to the second surface 3002 of the moisture absorption and exhaust component 300, so that the height of the third space 3302 and the fourth space 3402 remain unchanged. By arranging the top wall 3101 of the first drying module shell and the first surface 3001 of the moisture absorption and exhaust component 300, as well as the bottom plate 3201 of the second drying module shell and the second surface 3002 of the moisture absorption and exhaust component 300 in parallel with each other in the fan-shaped area of the regeneration zone, the flow height of the drying airflow remains unchanged, so that the heat received by each part of the moisture absorption and exhaust component 300 rotating through the regeneration zone is uniform, thereby achieving basically the same regeneration effect and avoiding the phenomenon of local overheating in the regeneration zone.

In one embodiment, as shown in Figure 7b, the first drying module housing 310, the moisture absorption and exhaust component 300, and the second drying module housing 320 can also be arranged vertically. This vertical arrangement also ensures that in the regeneration area, the distances between the first drying module housing top wall 3101, the second drying module housing bottom plate 3201, and the corresponding surfaces of the moisture absorption and exhaust component 300 remain constant.

In addition, preferably, as shown in Figure 8, a slanted wall 3103 is radially arranged in the dehumidification area of the first space near the first air flow outlet, and the slanted wall 3103 smoothly and gradually moves away from the first surface 3001 of the moisture absorption and discharge component 300, so that the top wall 3101 of the first drying module shell forms an approximately stepped shape in the direction in which the slanted wall 3103 extends.

Preferably, the second drying module housing 320 includes a second drying module bottom plate 3201 and circumferential sidewalls protruding from the second drying module bottom plate 3201, forming a recessed portion that serves as a second space 3202. Three second dividers 321 are positioned within the second space 3202 to separate it into a dehumidification zone, a cooling zone, and a regeneration zone (not shown). Correspondingly, the first drying module housing 310 includes a first drying module top wall 3101 and circumferential sidewalls, forming a recessed portion that serves as the first space. Three first dividers 311 are radially arranged along the first drying module housing 310 at locations corresponding to the three second dividers 321 within the first space 3102. This divides the first drying module housing 310 into a dehumidification area, a cooling area, and a regeneration module installation area (not shown). The recessed structures of the first drying module housing 310 and the second drying module housing 320 are arranged opposite each other, ensuring a sealed connection between the first drying module housing 310 and the second drying module housing 320. The moisture absorption and dehumidification component 300 is used to absorb moisture from the circulating airflow in the dehumidification zone during rotation, cool the component 300 in the cooling zone, and discharge the moisture absorbed in the dehumidification zone through the dehumidification airflow in the regeneration zone. Preferably, the dehumidification zone, cooling zone, regeneration zone, and regeneration module mounting area are generally fan-shaped. Similarly, the regeneration module mounting area in this embodiment houses the regeneration module 31. The structure and mounting method of the regeneration module 31 are identical to those described previously and will not be further elaborated here.

Preferably, the area of the dehumidification zone of the second space 3202 is greater than or equal to the area of the cooling zone and the area of the regeneration zone. Preferably, the ratio of the area of the dehumidification zone to the area of the cooling zone and the area of the regeneration zone is approximately 4:1:1 to 1:1:1.

Example 2:

In this embodiment, the structure of the clothes treating apparatus 1 is substantially the same as that in the embodiment 1 and will not be described again here.

In particular, the second space 3202 has a first air inlet 301, and the drying air passes through the first air inlet 301 and passes through the second space 3202, the moisture absorption and exhaust component 300 and the first space 3102 in sequence; along the overall flow direction of the drying air in the second space 3202, in the dehumidification area, at least part of the position away from the first air inlet 301 has a different cross-sectional area than the first air inlet 301.

It should be understood that the "overall flow direction" of the drying airflow in the second space 3202 refers to the general direction of the drying airflow formed by the airflow flowing through the space between the second surface 3002 of the moisture absorption and exhaust component 300 and the bottom plate 3201 of the second drying module housing, as a whole, i.e., the direction generally from the first airflow inlet 301 to the first airflow outlet 304, as shown by the arrow in Figure 5. It should be noted that within the second space 3202, a small portion of the drying airflow may flow in a direction different from the overall flow direction. For example, when the drying airflow passes from the second space 3202 through the moisture absorption and exhaust component 300 to the first space 3102, this portion of the drying airflow does not cause the "overall flow direction" to change.

This arrangement can narrow the shape of the air path through which the drying air flows, thereby effectively compensating for the pressure loss of the air flow when the moisture in the drying air flow is continuously adsorbed, resulting in a decrease in the drying air flow density.

Preferably, viewed along the overall flow direction of the drying airflow in the second space 3202 , in the dehumidification zone, the area of the cross section at the first airflow inlet 301 is larger than the area of the cross section at least partially away from the first airflow inlet 301 .

Preferably, viewed along the overall flow direction of the drying airflow in the second space 3202, in the dehumidification zone, the cross-sectional area gradually decreases in a direction gradually away from the first airflow inlet 301.

Preferably, viewed from the overall flow direction of the drying airflow in the second space 3202, in the dehumidification area, at least a portion of the second drying module shell bottom plate 3201 gradually tilts upward and extends, so that the cross-section of the second space 3202 along the radial direction of the moisture absorption and discharge component 300 is roughly a right-angled trapezoid.

It can be understood that the "cross-section" referred to here refers to the vertical cross-section of the space formed by the bottom plate 3201, the side wall and the corresponding surface of the moisture absorption and exhaust component 300 of the second drying module shell, viewed from the overall flow direction of the drying air flow in the second space 3202.

Through the above preferred implementation, the shape of the air path through which the drying air flows can be converged. This effectively compensates for air pressure loss when moisture in the drying air is continuously adsorbed, resulting in a decrease in drying air density. This allows the airflow pressure and flow rate to remain stable, ensuring sufficient contact with the moisture absorption and dehumidification component 300. The technical solution of this embodiment of the present invention enables the drying airflow to achieve a relatively uniform adsorption effect at all locations within the moisture absorption and dehumidification component 300.

In summary, the present invention provides a clothing processing device 1. By configuring the dehumidification zone within the second space 3202 to converge within the airflow path, the device effectively compensates for airflow pressure loss when moisture in the drying airflow is continuously adsorbed, resulting in a decrease in drying airflow density. This maintains stable airflow pressure and velocity, ensuring sufficient contact with the moisture adsorption and dehumidification component 300. Consequently, the present invention's technical solution enables the moisture adsorption and dehumidification component 300 to achieve a better adsorption effect on the drying airflow flowing therein.

In addition, by keeping the distance between the bottom plate 3201 of the second drying module shell located in the regeneration area of the second space 3202 and the corresponding surface of the moisture absorption and exhaust component 300 unchanged, the flow height of the drying airflow in the regeneration area of the drying module 3 remains unchanged, so that the heat received by each part of the moisture absorption and exhaust component 300 rotating through the regeneration area is uniform, achieving basically the same regeneration effect and avoiding the occurrence of local overheating in the regeneration area.

In addition, by providing a diverter 322 along the direction of the drying air flow on the bottom plate 3201 of the second drying module shell in the dehumidification area, the drying air flow flowing into the dehumidification area can be diverted, with one part entering the area close to the center of the circle and the other part entering the area close to the periphery of the moisture absorption and exhaust component 300, so that the drying air flow flowing into the airflow channel is more dispersed and more uniform, and can contact the moisture absorption and exhaust component 300 more evenly, thereby improving the moisture absorption efficiency of the moisture absorption and exhaust component 300.
