DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] The following describes a laundry processing device 100 according to an embodiment of the present invention with reference to the accompanying drawings. The laundry processing device 100 may be a heat pump dryer or a washer-dryer.

[0028] like Figure 1 , Figure 3-Figure 4 As shown, the laundry processing device 100 according to the embodiment of the present invention may include: a door body 20 , a housing 1 , a drum 2 , an air duct member 3 and a fan assembly 4 .

[0029] Specifically, the housing 1 has a containing space, and the drum 2 can be rotatably disposed in the containing space of the housing 1, for example, the rotation center line of the drum 2 is horizontally disposed.

[0030] The air duct member 3 and the fan assembly 4 are both located in the casing 1. A front cylinder opening is provided at the front of the drum 2, and the door body 20 is used for opening and closing the front cylinder opening.

[0031] The drum 2 has an air inlet 23 and an air outlet 24, and the air inlet 23 and the air outlet 24 are spaced apart in the axial direction of the drum 2. Figure 1 As shown, the air inlet 23 is disposed at the rear of the drum 2, and the air outlet 24 is disposed at the front of the drum 2. In some embodiments, the air inlet 23 may be disposed at the front of the drum 2, and the air outlet 24 may be disposed at the rear of the drum 2.

[0032] The air duct member 3 and the drum 2 are arranged in the radial direction of the drum 2. It can be understood that the air duct member 3 and the drum 2 are arranged in the radial direction of the drum 2, and can be arranged in any radial direction. Figure 1 As shown, the air duct member 3 is arranged below the drum 2. In some embodiments, the air duct member 3 is arranged above the drum 2, which is not specifically limited here. The air duct member 3 has an air duct 31, and the air duct 31 extends in the axial direction of the drum 2. The fan assembly 4 includes a volute 41 and an impeller 42 located in the volute 41, the volute 41 and the air duct member 3 are arranged in the axial direction of the drum 2, the volute 41 is directly connected with the air duct 31 to form an external air duct, and the external air duct is connected with the air inlet 23 and the air outlet 24. Among them, it can be understood that "the volute 41 is directly connected with the air duct 31" means that the airflow directly enters the air duct 31 from the volute 41 without passing through other intermediate pipelines, or the airflow directly enters the volute 41 from the air duct 31 without passing through other intermediate pipelines.

[0033] In some embodiments, Figure 3-Figure 4 As shown, the volute 41 has an air inlet 411 and an air outlet 412. When the air inlet 411 of the volute 41 is connected to the air duct 31, the air outlet 412 of the volute 41 is connected to the air inlet 23, and the end of the air duct 31 away from the volute 41 is connected to the air outlet 24. When the air outlet 412 of the volute 41 is connected to the air duct 31, the air inlet 411 of the volute 41 is connected to the air outlet 24, and the end of the air duct 31 away from the volute 41 is connected to the air inlet 23. In this way, the drum 2 and the external air duct can form an airflow circulation channel.

[0034] Specifically, generally, if Figure 4 As shown, since the volute 41 includes a volute chamber 413 and a diffuser 414, the impeller 42 is located in the volute chamber 413, the diffuser 414 is connected to the peripheral wall of the volute chamber 413 and extends radially outward from the volute chamber 413, the air inlet 411 is arranged on the end face of one axial end of the volute chamber 413, and the air outlet 412 is arranged at the end of the diffuser 414 away from the volute chamber 413.

[0035] When the air inlet 411 of the volute 41 is connected to the air duct 31, the volute chamber 413 is directly opposite to and connected to the air duct 31 in the axial direction of the drum 2, and the air outlet 412 on the diffuser 414 is connected to the air inlet 23; optionally, the axis of the volute chamber 413 is parallel to the axis of the drum 2. In this way, the airflow can directly enter the volute chamber 413 from the air duct 31 without passing through other intermediate pipelines, which can greatly shorten the flow path of the airflow.

[0036] When the air outlet 412 of the volute 41 is connected to the air duct 31, the diffuser 414 and the air duct 31 can be directly opposite to each other in the axial direction of the drum 2 and directly connected, and the air inlet 411 of the volute chamber 413 is connected to the air outlet 24 of the air duct 31. Optionally, the axis of the diffuser 414 is parallel to the axis of the drum 2. Among them, "the diffuser 414 and the air duct 31 can be directly opposite to each other in the axial direction of the drum 2 and directly connected", so that the airflow can directly enter the air duct 31 from the diffuser 414 without passing through other intermediate pipelines, which can greatly shorten the flow path of the airflow.

[0037] In addition, the laundry processing device 100 according to the embodiment of the present invention may further include: an evaporator 8, a condenser 9, a compressor 10 and a throttling element (not shown in the figure). The evaporator 8, the condenser 9, the compressor 10 and the throttling element constitute a refrigerant circulation flow path. The evaporator 8 and the condenser 9 can be located in the air duct 31, and the evaporator 8 is located upstream of the condenser 9. The low-temperature and low-pressure refrigerant absorbs heat in the evaporator 8 to become a low-temperature gas, is compressed into a high-temperature and high-pressure gas by the compressor 10, and then releases heat in the condenser 9 to become a high-temperature liquid. It is cooled and reduced in pressure by the throttling element to become a low-temperature and low-pressure gas-liquid two-phase state, and the cycle is repeated; and when the impeller 42 is working, it can drive the airflow to circulate in the airflow circulation channel composed of the air duct 31, the volute 41 and the drum 2. During the circulation process of the airflow, when it flows into the drum 2, it can take away the moisture of the wet clothes and turn into medium and low-temperature humid air, and then it is discharged from the air outlet 24 of the drum 2 and enters the external air duct again, and is cooled and dehumidified by the evaporator 8 to become low-temperature dry air, and the low-temperature dry air is heated up to high-temperature dry air through the condenser 9, and the cycle is repeated.

[0038] In the related art, the air duct member 31 and the volute 41 are connected through a transfer tube. For example, the air duct member 31 is arranged on the left side below the drum, and the volute 41 is arranged on the right side below the drum, and they are connected through a connecting pipe. According to this structure, during the flow of the airflow, the airflow has two turns at the first end and the second end of the transfer tube. The airflow circulation channel of the clothing processing device 100 is relatively long, and there are many turns in the airflow circulation channel. When the airflow flows in the airflow circulation channel, the path is tortuous, and the resistance along the way and the local resistance cannot be avoided. In addition, another problem caused by the long path is that the hot air will radiate heat outward on the wall surface along the way, causing energy loss and reducing the drying efficiency.

[0039] In view of this, the clothing processing device 100 according to the embodiment of the present invention arranges the volute 41 and the air duct member 3 in the axial direction of the drum 2, and the volute 41 is directly connected to the air duct 31, which not only simplifies the structure, but also helps to shorten the length of the external air duct, and helps to reduce the bending corners of the external air duct, thereby reducing the flow resistance, reducing the wind resistance, reducing the noise, and at the same time reducing the heat radiation along the way and improving the heat exchange efficiency. In addition, due to the reduction of flow resistance and wind resistance, the amount of circulating air becomes larger. Compared with the related art, under the premise of ensuring the same air volume, the air volume can also be reduced by reducing the speed of the impeller 42 (such as reducing the speed of the impeller 42 by adjusting the reduction ratio, by reducing the size of the impeller 42, etc.), thereby reducing the wind noise from the source.

[0040] In some embodiments of the present invention, the air outlet 412 of the volute 41 is connected to the air duct 31, the diffuser 414 and the air duct 31 may be directly opposite in the axial direction of the drum 2 and the diffuser 414 extends along the axial direction of the drum, and the air inlet 411 of the volute chamber 413 is connected to the air outlet 24 of the air duct 31. This can further ensure that the airflow in the diffuser 414 can flow smoothly to the air duct 31, reducing wind resistance.

[0041] In some embodiments of the present invention, the air inlet 23 and the air outlet 24 are both arranged on the peripheral wall of the drum 2. Such an arrangement can facilitate the communication between the air inlet 23 and the air outlet 24 and the external air duct, especially facilitate the communication between the air inlet 23 arranged on the peripheral wall of the drum 2 and the air outlet 412 of the volute 41 located on the diffuser 414, which can help reduce the bending corners of the external air duct, thereby reducing flow resistance, wind resistance, and noise.

[0042] Reference Figure 1-Figure 2As shown, in some embodiments of the present invention, the drum 2 includes a drum body 21 and a connecting ring 22, the rear side of the drum body 21 is open, the connecting ring 22 is connected to the rear end of the drum body 21 and extends in a ring shape along the circumference of the drum 2, the connecting ring 22 is arranged obliquely relative to the central axis of the drum 2, and the connecting ring 22 has an air inlet 23. Such an arrangement can facilitate the communication between the air inlet 23 and the external air duct, especially facilitate the communication between the air inlet 23 and the air outlet 412 of the volute 41 located on the diffuser 414, and can help reduce the bending corners of the external air duct, thereby reducing the flow resistance, reducing the wind resistance, and reducing the noise.

[0043] In some specific examples of the present invention, in the direction from front to back, the connecting ring 22 is inclined toward the direction close to the central axis of the drum 2, and the clothing processing device 100 includes: a sealing cover 5, the axial front end of the sealing cover 5 is rotatably connected to the drum 2, and the sealing cover 5 is arranged around the outer periphery of the connecting ring 22, the inner peripheral wall of the sealing cover 5 is spaced apart from the outer peripheral wall of the connecting ring 22 to define an annular air intake channel 6, the volute 41 is connected to the air inlet 23 through the air intake channel 6, the sealing cover 5 and the connecting ring 22 can facilitate the definition of the air intake channel 6, so as to facilitate the setting of the air inlet 23 on the entire circumference of the connecting ring 22, so as to realize air intake on the entire circumference of the connecting ring 22 and improve the air intake effect.

[0044] In some embodiments of the present invention, the volute chamber 413 of the volute 41 is directly opposite to the air duct 31 in the axial direction of the drum 2, that is, the axial direction of the volute chamber 413 of the volute 41 is in the same direction as the axial direction of the drum 2, and the volute chamber 413 and the air duct 31 are directly opposite to each other in the axial direction of the volute chamber 413, and the air inlet 411 of the volute chamber 413 is connected to the air duct 31, which is conducive to further shortening the length of the external air duct, and is conducive to reducing the bending corners of the external air duct, thereby reducing the flow resistance, reducing the wind resistance, reducing the noise, and at the same time reducing the heat radiation along the way and improving the heat exchange efficiency. In addition, due to the reduction of flow resistance and wind resistance, the amount of circulating air becomes larger, so compared with the related art, under the premise of ensuring the same air volume, the air volume can also be reduced by reducing the speed of the impeller 42 (such as reducing the speed of the impeller 42 by adjusting the reduction ratio, by reducing the size of the impeller 42, etc.), thereby reducing the wind noise from the source.

[0045] In some embodiments of the present invention, the rear end of the sealing cover 5 protrudes backwards from the rear end of the connecting ring 22, thereby facilitating further improving the air intake effect and preventing air leakage.

[0046] In some embodiments of the present invention, in the radial direction of the drum 2, the volute 41 is directly opposite to and connected to the sealing cover 5, and the air outlet 412 of the diffuser 414 is located at the peripheral wall of the sealing cover 5. In this way, when the airflow flows from the air duct 31 to the drum 2 through the volute 41, the airflow can be directly diverted through the volute 41, and no other diverting channels are required. Not only the structure becomes simpler, but also it is conducive to further shortening the length of the external air duct, and it is conducive to reducing the bending corners of the external air duct, thereby reducing the flow resistance, reducing the wind resistance, reducing the noise, and at the same time reducing the heat radiation along the way, and improving the heat exchange efficiency. In addition, due to the reduction of flow resistance and wind resistance, the air volume of the circulating flow becomes larger. Compared with the related art, under the premise of ensuring the same air volume, the air volume can also be reduced by reducing the speed of the impeller 42 (such as reducing the speed of the impeller 42 by adjusting the reduction ratio, by reducing the size of the impeller 42, etc.), thereby reducing the wind noise from the source.

[0047] In some embodiments of the present invention, the volute 41 and the sealing cover 5 are an integral part. The integral part structure can not only ensure the structural and performance stability of the volute 41 and the sealing cover 5, but also facilitate molding and simple manufacturing, and eliminate unnecessary assembly parts and connection procedures, greatly improve the assembly efficiency of the volute 41 and the sealing cover 5, ensure the reliability of the connection between the volute 41 and the sealing cover 5, and furthermore, the integrally formed structure has higher overall strength and stability, is more convenient to assemble, and has a longer service life.

[0048] In some embodiments of the present invention, the volute 41 and the sealing cover 5 are integrally formed.

[0053] In some embodiments of the present invention, Figure 2 As shown, the sealing cover 5 is connected to the drum body 21 and a sealing member 7 is provided between the two. Specifically, since the drum 2 can rotate relative to the sealing cover 5 when the drum 2 is working, in order to avoid the problem of air leakage between the sealing cover 5 and the drum 2 during the rotation of the drum 2, a sealing member 7 is provided between the sealing cover 5 and the drum body 21.

[0054] Optionally, the sealing member 7 is a sealing felt. In this way, the cost is relatively low. Of course, the present invention is not limited thereto, and the sealing member 7 can also be other sealing members 7 as long as the rotation of the drum 2 relative to the sealing cover 5 is not affected.

The fact that each air inlet hole group includes at least one air inlet hole 231 should be understood as follows: the number of air inlet holes 231 in different air inlet hole groups may be the same or different, but each air inlet hole group includes at least one air inlet hole 231.

[0058] By setting a plurality of groups of air inlet holes on the connecting ring 22, the plurality of groups of air inlet holes are arranged at intervals in the circumferential direction of the connecting ring 22, and each group of air inlet holes includes at least one air inlet hole 231, so that no matter how the drum 2 rotates, air can be introduced in the circumferential direction of the connecting ring 22, which is beneficial to improving the uniformity of the air intake and improving the air intake effect.

[0059] In some embodiments of the present invention, multiple groups of air inlet holes are evenly spaced and arranged in the circumferential direction of the connecting ring 22. Therefore, no matter how the drum 2 rotates, air can be introduced in the circumferential direction of the connecting ring 22, which is conducive to improving the uniformity of air introduction and improving the air introduction effect.

[0061] In some embodiments of the present invention, the air inlet hole group includes a plurality of air inlet holes 231, and the plurality of air inlet holes 231 are evenly spaced and arranged in the radial direction of the connecting ring 22. For example, the entire connecting ring 22 is evenly distributed with a plurality of air inlet holes 231.

Such an arrangement is conducive to reasonably optimizing the structural layout and improving the compactness of the structure of the laundry processing device 100.

[0064] Specifically, for example, the fan assembly 4 includes a drive motor 43 for driving the impeller 42 to rotate, one end of the belt is connected to the motor shaft of the drive motor 43, the other end of the belt is connected to the connecting shaft of the impeller 42, and the belt is located on the rear side of the volute chamber 413, wherein, in the horizontal plane, the drive motor 43 and the volute 41 are respectively located on the left and right sides of the rotation center line of the drum 2, and this transmission method can very conveniently change the rotation speed of the impeller 42 through the reduction ratio.

[0065] In some embodiments of the present invention, Figure 1 As shown, the clothes processing device 100 includes a filter 30, which is arranged at the air outlet 24, so that the lint and the like carried in the air flow can be filtered out to prevent the lint and the like from adhering to the evaporator 8 and the condenser 9 and affecting the heat exchange effect.

[0066] In some embodiments of the present invention, the filter screen 30 may be a metal screen. By configuring the filter screen 30 as a metal screen, the structural strength of the filter screen 30 is improved and the service life is prolonged.

[0067] In some optional embodiments of the present invention, the throttling element is an electronic expansion valve, a capillary tube and a thermal expansion valve. Such throttling elements have lower costs.

[0068] In some embodiments of the present invention, in order to improve the heat exchange effect, at least one of the evaporator 8 and the condenser 9 is a microchannel heat exchanger, that is, the evaporator 8 can be a microchannel heat exchanger, the condenser 9 can be a microchannel heat exchanger, and the evaporator 8 and the condenser 9 can both be microchannel heat exchangers.

[0069] In some embodiments of the present invention, the microchannel heat exchanger may include a first header, a second header, and a plurality of heat exchange flat tubes. Specifically, the first header and the second header are arranged in parallel and spaced apart. For example, the first header and the second header are respectively arranged horizontally, and the first header and the second header are arranged in parallel and spaced apart. For another example, the first header and the second header are respectively arranged vertically, and the first header and the second header are arranged in parallel and spaced apart.

[0070] A plurality of heat exchange flat tubes are arranged between the first header and the second header at intervals. For example, each heat exchange flat tube is welded to the first header and the second header, respectively, so that each heat exchange flat tube is fixed between the first header and the second header.

[0071] Specifically, each heat exchange flat tube is connected to the first header and the second header, and each heat exchange flat tube has multiple medium flow channels. Specifically, for example, the first header has a medium inlet and multiple branch ports, the second header has a medium outlet and multiple header ports, the multiple branch ports, the multiple heat exchange flat tubes and the multiple header ports are respectively arranged in a one-to-one correspondence, and the two ends of each heat exchange flat tube are respectively connected to the corresponding header port and the branch port. Thus, the heat exchange medium, such as the refrigerant, entering the first header from the medium inlet can flow to the medium flow channels of the corresponding heat exchange flat tubes through the multiple branch ports, and then flow to the second header through the corresponding header port. The refrigerant flows to the second header and is discharged from the medium outlet. Optionally, the medium inlet may be located at one axial end of the first collecting pipe, multiple diversion ports may be provided on the side wall of the first collecting pipe and spaced apart along the axial direction of the first collecting pipe, and the medium outlet may be located at one axial end of the second collecting pipe, multiple collecting ports may be provided on the side wall of the second collecting pipe and spaced apart along the axial direction of the second collecting pipe.

[0072] Each heat exchange flat tube is formed in a spiral shape to define a spiral medium flow channel. Therefore, the spiral heat exchange flat tube is not only conducive to increasing the surface area of ​​the heat exchange flat tube and improving the heat exchange effect, but also the spiral medium flow channel in the heat exchange flat tube can cause the heat exchange medium to generate longitudinal rotation and secondary vortex when flowing, thereby enhancing the disturbance of the heat exchange medium in the medium flow channel, greatly improving the heat transfer coefficient, and greatly improving the performance of the dehumidifier.

[0073] In some embodiments of the present invention, a plurality of heat exchange flat tubes are arranged in parallel, which is beneficial to optimizing the structure of the microchannel heat exchanger and simplifying the processing of the microchannel heat exchanger.

[0074] Optionally, the rotation directions of the plurality of heat exchange flat tubes are the same. That is, the plurality of heat exchange flat tubes generate spirals in the same direction. Thus, not only is the structure simple, but also it is conducive to optimizing the appearance of the microchannel heat exchanger. Of course, it is understandable that the rotation directions of the plurality of heat exchange flat tubes can also be different.

[0075] In some embodiments of the present invention, each heat exchange flat tube is in a regular spiral shape. For example, in the length direction of the heat exchange flat tube, the pitch of each heat exchange flat tube remains unchanged. Thus, not only is the structure simple, but also it is conducive to optimizing the appearance of the microchannel heat exchanger.
