[0068] To enable those skilled in the art to more clearly understand this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0069] Figure 1 shows a schematic diagram of a washer-dryer combo according to some embodiments of the present disclosure. For clarity, part of the outer casing of the washer-dryer combo is omitted in Figure 1. Referring to Figure 1, the washer-dryer combo W includes a drum R and a drying module D. The drying module D includes a disc module D1, a moisture absorption channel D2, and a moisture exhaust channel D3. The moisture absorption channel D2 is provided with a moisture absorption channel D2 inlet and a moisture absorption channel D2 outlet. The drum R is connected to both the moisture absorption channel D2 inlet and outlet, and a circulating fan D23 is also provided in the moisture absorption channel D2 to form a circulating moisture-absorbing airflow within the drum R and the moisture absorption channel D2. A moisture exhaust fan D37 is provided in the moisture exhaust channel D3 to form a moisture exhaust airflow within the moisture exhaust channel D3. The rotary disc module D1 is positioned within the paths of the moisture absorption channel D2 and the moisture exhaust channel D3, ensuring that both the moisture absorption and exhaust airflows pass through it. This allows the rotary disc module D1 to absorb moisture from the moisture absorption airflow during rotation and expel the absorbed moisture through the exhaust airflow. Of course, the washer-dryer combo W may also include, but is not limited to, an outer casing with at least a clothes loading / unloading port and a detergent dispensing port, a door for sealing the clothes loading / unloading port, display and operating devices arranged on the outer casing, a frame, a controller, a drain pipe, and other components to achieve the washing and drying functions of clothes and to control the washer-dryer combo.

[0070] In related technologies, a condenser assembly is installed inside the housing to condense and remove moisture from the exhaust airflow, generating cooling water. However, the condensate from the condenser assembly and the cooling water generated by the condenser assembly are discharged through corresponding pipelines, resulting in a dense pipeline layout, which is not conducive to production and assembly.

[0071] Based on this, the present disclosure provides a condensation component, a drying module, and electrical equipment, which aim to at least partially solve the technical problem of dense pipeline layout, which is not conducive to production and assembly.

[0072] In a first aspect, this disclosure provides a condensing assembly C. Figure 2 shows a schematic diagram of the structure of a drying module in one or more embodiments of this disclosure; Figure 3 shows a schematic diagram of the structure of the condensing assembly in the drying module of Figure 2, with the top portion of the condensing assembly omitted for clarity; Figure 4 shows an internal schematic diagram of the condensing cavity in the condensing assembly of Figure 3. Referring to Figures 2-4, the condensing assembly C includes a condensing cavity 2 and a condenser 3. The condensing cavity 2 is provided with a drain outlet 21, the condenser 3 is disposed inside the condensing cavity 2, and the water outlet 31 of the condenser 3 is disposed inside the condensing cavity 2. The condensed water drawn from the water outlet 31 of the condenser 3 is discharged through the drain outlet 21.

[0073] According to one or more embodiments of the present disclosure, the condenser 3 of the condenser assembly C is disposed within the condensation chamber 2. The hot and humid airflow introduced into the condensation chamber 2 is condensed and absorbed by the condenser 3 to form cooling water, which is discharged through the drain port 21. Since the outlet of the condenser 3 is disposed within the condensation chamber 2, the condensate from the condenser 3 is also discharged through the drain port 21. Thus, the condensate from the condenser 3 and the cooling water generated by the condenser 3 can be discharged through a single drain port 21. Correspondingly, only one pipeline connected to the drain port 21 is needed, thereby simplifying the pipeline layout and improving production assembly efficiency. The condenser assembly C of the present disclosure will be further described below with reference to Figures 3-14.

[0074] Figure 5 shows a schematic diagram of the structure of the first housing of the drying module, and Figure 6 shows an enlarged schematic diagram of point A in Figure 5. Referring to Figures 5 and 6, according to one embodiment of this disclosure, the condensing chamber 2 has a top, a bottom, and side walls. The top and bottom are arranged opposite each other and connected by the side walls to form a generally square condensing chamber. An air inlet 22 is provided on the side of the condensing chamber 2. The exhaust airflow enters the condensing chamber 2 through the air inlet 22, and after being condensed and absorbed by the condenser 3 inside the condensing chamber 2, cooling water is generated. The condensate from the condenser 3 and the generated cooling water are discharged through the drain outlet 21 at the bottom of the condensing chamber 2. According to another embodiment of this disclosure, the condensing chamber 2 can also have a columnar structure, which can be specifically designed according to the shape of the condenser 3.

[0075] According to one embodiment of this disclosure, a single drain outlet 21 may be provided, and the drain outlet 21 has a large output aperture. According to another embodiment of this disclosure, multiple drain outlets 21 may be provided, and the multiple drain outlets 21 are arranged in a grid pattern to provide a certain filtering function.

[0076] Referring to Figures 5 and 6, the drain outlet 21 of the condenser chamber 2 can be connected to a downwardly extending drain pipe 4 to drain the condensate using the weight of the water or a pump. The drain pipe 4 can be a corrugated pipe structure and made of PP (polypropylene) + TPE (thermoplastic elastomer) material, which avoids deformation and water retention caused by using rubber materials. According to one embodiment of this disclosure, the drain pipe 4 can be connected to the outside to discharge the condensate from the electrical equipment. According to another embodiment of this disclosure, the drain pipe 4 can also be connected to the inside of the drum R to recover the condensate into the drum R for reuse.

[0077] Figure 9 shows a structural schematic diagram of the first shell in Figure 5 from another perspective, and Figure 10 shows an enlarged schematic diagram of point B in Figure 9. Referring to Figures 9 and 10, a recess 23 can be provided at the bottom of the condenser cavity 2, and a drain outlet 21 is disposed within the recess 23. The recess 23 can collect the condensate and generated cooling water from the condenser 3, facilitating the drainage of the condensate. It can be understood that the recess 23 is recessed towards the bottom of the cavity relative to the inner cavity of the condenser cavity 2. If viewed from the outside of the condenser cavity 2, the recess 23 appears to bulge outwards.

[0078] Referring to Figure 10, the bottom of the condensing cavity 2 may include a drain portion 231 and a connecting portion 232. The drain portion 231 is disposed within the vertical projection of the condensing cavity 2. The top of the connecting portion 232 is connected to the side wall of the condensing cavity 2, and the bottom of the connecting portion 232 extends downward toward the condensing cavity 2 and connects to the periphery of the drain portion 231 to form a recess 23. The drain outlet 21 is disposed on the drain portion 231.

[0079] Referring to Figure 10, the connecting portion 232 forming the bottom of the condensing cavity 2 may be provided with a clearance area 232a to avoid corresponding components on the electrical equipment. According to one embodiment of this disclosure, the clearance area 232a may include a sloped structure; the connecting portion 232 may have three sloped structures as the clearance area 232a; the connecting portion 232 may also have two, four, or more sloped structures as the clearance area 232a. According to another embodiment of this disclosure, the clearance area 232a may also be an arc-shaped structure or a stepped structure, or a combination of two or more of these structures.

[0080] Referring to Figures 6 and 10, the sidewalls of the condenser chamber 2 include a first sidewall 24 and a second sidewall 25 facing each other. An air inlet 22 for introducing dehumidifying airflow is provided on the first sidewall 24. Regarding the first sidewall 24 and the second sidewall 25, the drain portion 231 is closer to the second sidewall 25 and is offset from the vertical centerline of the condenser chamber 2. The portion of the connecting portion 232 located between the drain portion 231 and the first sidewall 24 can be configured as the aforementioned clearance area 232a.

[0081] Referring to Figure 10, according to one embodiment of this disclosure, the portion of the drainage section 231 facing the second sidewall 25 can be on the same vertical plane as the second sidewall 25, so as to expand the clearance area of ​​the clearance region 232a while ensuring a flat appearance, thus having better practicality. According to another embodiment of this disclosure, the drainage section 231 can also be disposed on the inner side of the second sidewall 25.

[0082] In some embodiments, to ensure the normal operation of the condenser 3, the condenser 3 is suspended inside the condensing chamber 2, so that the plane containing the bottom of the condenser 3 is at a certain distance from the bottom of the condensing chamber 2. By suspending the condenser 3, contact between the condenser 3 and the water collected in the condensing chamber 2 can be avoided to a certain extent, facilitating the collection and discharge of condensate and cooling water at the bottom of the condensing chamber 2.

[0083] Referring to Figures 4 and 6, multiple support members 5 can be provided on the bottom of the condensing chamber 2. The tops of the multiple support members 5 are on the same plane, and the condenser 3 is assembled on the multiple support members 5 so that the condenser 3 can be in a horizontal position to ensure the normal operation of the condenser 3.

[0084] According to one embodiment of this disclosure, four support members 5 may be provided. The four support members 5 are arranged in a square shape. Among the four support members 5, two support members 5 near the first sidewall 24 are defined as first support members 51; and two support members 5 near the second sidewall 25 are defined as second support members 52. Figure 11 shows a structural schematic diagram of the first support member. Referring to Figure 11, a first positioning plate 53 is provided on the first support member 51. The first positioning plate 53, the first sidewall 24, and the first support member 51 are constructed to form a first positioning groove 55. Figure 12 shows a structural schematic diagram of the second support member. Referring to Figure 12, two second positioning plates 54 are provided with a gap on the second support member 52. The two second positioning plates 54 and the second support member 52 are constructed to form a second positioning groove 56.

[0085] Figure 13 shows a schematic diagram of the condenser in a drying module according to one or more embodiments of the present disclosure, and Figure 14 shows a schematic diagram of the condenser of Figure 13 assembled in the condensing cavity. Referring to Figures 13 and 14, connecting frames 32 are respectively provided at both ends of the condenser 3. The connecting frame 32 may include two vertically arranged connecting plates 33, which are respectively inserted into the first positioning groove 55 and the second positioning groove 56 to realize the assembly of the connecting frame 32 on the support member 5, so as to assemble the condenser 3 into the condensing cavity 2.

[0086] Since the first positioning groove 55 is constructed by the first positioning plate 53, the first side wall 24, and the first support member 51, and the air inlet 22 is located on the first side wall 24, the condenser 3 can be attached to the first side wall 24, thereby maximizing the intake of the dehumidifying airflow from the air inlet 22 into the condenser 3 and improving condensation efficiency. Furthermore, since the second positioning groove 56 is constructed by the two second positioning plates 54 and the second support member 52, there is a distance between the condenser 3 and the second side wall 25. The outlet 31 of the condenser 3 can be inclined towards the second side wall 25, allowing the condensate from the condenser 3 to be introduced into the aforementioned recess 23 through the second side wall 25. This prevents the condensate from directly dripping into the recess 23 and causing splashing, thus reducing the noise generated by the condenser 3 during operation to a certain extent.

[0087] In a second aspect of this disclosure, a drying module D is provided. Referring to Figures 2 and 3, the drying module D includes a housing 1, the aforementioned condenser assembly C, and an exhaust fan D33. The housing 1 is provided with an exhaust channel D3 and an exhaust fan cavity D5. The aforementioned condenser assembly C is disposed within the housing 1. The exhaust channel D3, the condenser cavity 2, and the exhaust fan cavity D5 are sequentially connected. The exhaust fan D33 is connected to the exhaust fan cavity D5, so that the exhaust airflow generated within the housing 1 is led out through the exhaust channel D3 to the condenser 3, whereby the exhaust airflow is condensed into cooling water and discharged through the drain outlet 21.

[0088] The drying module D provided according to one or more embodiments of this disclosure simplifies the piping connection to the condenser assembly C, improving production assembly efficiency. Furthermore, since the dehumidification channel D3, the condenser 3, and the dehumidification fan cavity D5 for assembling the dehumidification fan D33 are all housed within the housing 1, the dehumidification fan D33 can be connected to the dehumidification channel D3 using the internal structure of the housing 1, achieving airtightness without the need for seals. This results in a simple and compact structure, facilitating production assembly.

[0089] It should be noted that the condenser component C of the drying module D can also adopt the technical solution in the related technology where the condensate and the generated cooling water of the condenser 3 are discharged through corresponding pipelines, or other types of solutions can be adopted, without limitation. The drying module D of this disclosure will be further described below with reference to Figures 2 and 5-6.

[0090] Figure 7 shows a top view of the drying module in Figure 2, and Figure 8 shows a cross-sectional view (AA) of Figure 7. Referring to Figures 5-8, the housing 1 contains a heat exchange chamber D6 for loading the disc module D1. A heating zone D61 is located within the heat exchange chamber D6, and a heating element (not shown) is installed within the heating zone D61. The inlet end D35 of the dehumidification channel D3 is connected to the edge of the heating zone D61. When the hygroscopic airflow passes through the disc module D1, the moisture in the hygroscopic airflow is absorbed by the disc module D1 and heated by the heating element to generate a dry airflow. This dry airflow is conveyed to the roller R to remove moisture from the roller R. Simultaneously with the generation of the dry airflow, dehumidified air is generated within the heating zone D61. The dehumidification fan D37 is activated, and the dehumidified air is drawn out through the dehumidification channel D3, thus forming the aforementioned dehumidified airflow within the dehumidification channel D3.

[0091] Referring to Figures 5, 6, and 8, the bottom of the condensing chamber 2 is lower than the outlet end D34 of the dehumidification channel D3 to prevent condensate from overflowing onto the moisture-absorbing turntable inside the housing 1 in case of abnormal condensate discharge, thus affecting the moisture absorption and dehumidification effect of the drying module D. In some embodiments, the part of the bottom of the housing 1 where the condensing chamber 2 is located can be appropriately lowered, or the bottom of the dehumidification channel D3 can be appropriately raised so that the vertical distance H1 between the bottom of the condensing chamber 2 and the outlet end D34 of the dehumidification channel D3 is between 40-60 mm (as shown in Figures 7 and 8). This vertical distance H1 can be 40 mm, 50 mm, 55 mm, or 60 mm.

[0092] Referring to Figures 5-8, a first guide section D31 is provided at the bottom of the outlet end D34 of the dehumidification channel D3. One end of the first guide section D31 is connected to the outlet end D34 of the dehumidification channel D3, and the other end is connected to the bottom of the air inlet 22. The height of one end of the first guide section D31 is higher than the height of the other end, that is, the end of the first guide section D31 connected to the outlet end D34 of the dehumidification channel D3 is higher than the end connected to the bottom of the air inlet 22. The first guide section D31 is used to guide the dehumidified airflow from the dehumidification channel D3 to the condenser 3 located in the condensation chamber 2. In some embodiments, the first guide section D31 can descend sequentially along the airflow direction of the dehumidified airflow. The first guide section D31 can be an inclined surface, an arc surface, or a combination of an inclined surface and an arc surface, which is not limited here.

[0093] Referring to Figures 5-8, the housing 1 further includes a second flow guide, which is disposed at the air inlet 22. The second flow guide includes a second flow guide portion D36 and a support portion 27. At least a portion of the second flow guide portion D36 is connected to the dehumidification channel D3, and at least a portion of the support portion 27 is connected to the side of the condensation chamber 2. In some embodiments, the dehumidification channel D3 has opposing first side portions D32 and second side portions D33. The first side portion D32 is connected to one side of the air inlet 22, and the other side of the air inlet 22 is provided with a support portion 27 extending into the interior of the air inlet 22. The second side portion D33 is connected to the support portion 27 through the second flow guide portion D36. The support portion 27 can be a plate disposed on the other side of the air inlet 22, which can be integrally formed with the side wall of the condensation chamber 2. The second flow guide portion D36 can be a plate integrally formed and connected to the second side portion D33 of the dehumidification channel D3 to guide the outward direction of the dehumidification airflow. In addition, the extended support 27 can also limit the displacement of the condenser 3, preventing the condenser 3 from detaching from the support block due to vibrations generated by the electrical equipment during operation, so as to ensure the normal operation of the condenser 3.

[0094] Referring to Figures 5 and 6, the cross-sectional dimension of the exhaust channel D3 near its outlet end D34 is smaller than the cross-sectional dimension of the exhaust channel D3 away from its outlet end D34, so that the size of the outlet end D34 of the exhaust channel D3 is reduced, so that the exhaust airflow can flow out to the condensation chamber 2 more quickly, thereby improving the condensation efficiency.

[0095] Referring to Figures 5, 6, and 8, according to one embodiment of this disclosure, the first side portion D32 and the second side portion D33, along with the edge of the heating region D61, are configured as the inlet end D35 of the first dehumidification channel D3. The second guide portion D36 and the portion of the first side portion D32 opposite to the second guide portion D36 are configured as the outlet end D34 of the first dehumidification channel D3. The cross-sectional dimension of the dehumidification channel D3 gradually decreases from the inlet end D35 to the outlet end D34, thereby reducing the size of the outlet end D34 and accelerating the flow of dehumidified air into the condensing cavity 2, thus improving condensation efficiency. According to another embodiment of this disclosure, only the cross-sectional dimension of the outlet end D34 of the first dehumidification channel D3 may be reduced, which also accelerates the flow of dehumidified air into the condensing cavity 2.

[0096] Referring to Figures 7 and 8, the drying module D also includes a wheel 6. The housing 1 is provided with a support portion 13 for mounting the wheel 6, which is horizontally or nearly horizontally arranged. The wheel 6 can rotate relative to the support portion 13, which is higher than the bottom of the condenser 3 to prevent condensate from overflowing onto the moisture-absorbing turntable inside the housing 1 in case of abnormal condensate discharge, thus affecting the moisture absorption and dehumidification effect of the drying module D. In some embodiments, the vertical distance H2 between the support portion 13 and the bottom of the condenser 3 is between 50 and 60 mm, and this vertical distance H2 can be 50 mm, 55 mm, or 60 mm.

[0097] Referring to Figures 5 and 6, an air outlet 26 can also be provided on the side wall of the condensing chamber 2. The air outlet 26 is connected to the dehumidifying fan chamber D5. The dehumidifying fan D37 can be located at the top of the condensing chamber 2 so that the dehumidifying airflow can be drawn into the condensing chamber 2 when the dehumidifying fan D37 is working.

[0098] Referring to Figures 5 and 6, according to one embodiment of this disclosure, the air outlet 26 and the air inlet 22 are respectively disposed on two adjacent side walls of the condensing cavity 2, so as to make the drying module D compact and reduce the size occupied by the drying module D. According to another embodiment of this disclosure, the air outlet 26 and the air inlet 22 may also be disposed on two opposite side walls of the condensing cavity 2.

[0099] Referring to Figure 6, the bottom of the dehumidifying fan cavity D5 is higher than the bottom of the condensing cavity 2 to prevent condensate from overflowing into the dehumidifying fan cavity D5 inside the housing 1 and affecting the normal operation of the dehumidifying fan D37 in case of abnormal condensate discharge. In some embodiments, the part of the bottom of the housing 1 where the condensing cavity 2 is located can be appropriately lowered; or, the bottom of the dehumidifying fan cavity D5 can be appropriately raised so that the vertical distance H1 between the bottom of the condensing cavity 2 and the bottom of the dehumidifying fan cavity D5 is between 40 and 60 mm. This vertical distance H1 can be 40 mm, 50 mm, 55 mm, or 60 mm, so that the bottom of the dehumidifying fan cavity D5 is approximately at the same height as the bottom of the outlet end D34 of the dehumidification channel D3.

[0100] According to one embodiment of this disclosure, the bottom of the first guide section D31 may have a height difference with the bottom of the condensing cavity 2. Since the bottom of the exhaust fan cavity D5 and the bottom of the condensing cavity 2 also have a height difference, the bottom of the condensing cavity 2 can form a circumferentially closed cavity to receive the cooling water generated by the condenser 3. According to another embodiment of this disclosure, the bottom of the first guide section D31 may also be at the same height as the bottom of the exhaust fan cavity D5, as long as the inlet end D35 of the condensing cavity 2 is higher than the bottom of the exhaust channel D3.

[0101] Referring to Figure 5, in some embodiments, a circulating fan cavity D7 is integrally formed within the housing 1. The circulating fan D23 is connected to the circulating fan cavity D7 to form a circulating moisture-absorbing airflow within the roller R and the moisture-absorbing channel D2. Since the circulating fan cavity D7 is integrally formed within the housing 1, the circulating fan D23 and the circulating fan cavity D7 can be connected using the internal structure of the housing 1, and airtightness requirements can be achieved without the need for sealing components. The structure is simple and compact, facilitating production and assembly.

[0102] Referring to Figure 5, the housing 1 can also have an integrally formed circulating fan mounting port D71, on which the circulating fan D23 is assembled, so that the airtightness requirement can be achieved without the need for a sealing element.

[0103] It should be noted that, in some embodiments, the top of the circulating fan cavity D7 may be provided with the aforementioned circulating fan mounting port D71. In other embodiments, the housing 1 may also be constructed with corresponding components to form the aforementioned circulating fan mounting port D71.

[0104] Figure 15 shows a schematic diagram of the first housing in some embodiments. Referring to Figure 15, the housing 1 also includes an air inlet channel D4 to draw out the drying airflow generated within the housing 1. The air inlet channel D4 and the exhaust channel D3 are spaced apart. A third guide section D41 is provided within the air inlet channel D4, connecting to the side of the air inlet channel D4 closest to the exhaust channel D3 and extending towards the side of the air inlet channel D4 furthest from the exhaust channel D3. This ensures a more uniform temperature of the drying airflow drawn out by the air inlet channel D4, improving the drying effect.

[0105] Referring to Figure 15, in some embodiments, the air inlet channel D4 has opposing third and fourth sides, with the third side being closer to the exhaust channel D3 than the fourth side. A third guide section D41 within the air inlet channel D4 is connected to the third side and extends towards the fourth side. Because the third side is closer to the exhaust channel D3 than the fourth side, and the heating area D61, where the heating element is located, is connected to the exhaust channel D3, the airflow temperature on the side where the third side is located is higher than the airflow temperature on the side where the fourth side is located. The third guide section D41 located on the third side can change the airflow direction on the third side, allowing the airflow on the third side and the airflow on the fourth side to mix before entering the drum, thus making the temperature of the incoming airflow more uniform and improving the drying effect.

[0106] The third guide section D41 can be an arc-shaped section, a sloped section, or a combination of arc-shaped and sloped sections; no restrictions are imposed here.

[0107] In some embodiments, the third airflow guide D41 may be a protrusion disposed in the air inlet channel D4, integrally formed on the third side to have sufficient strength for use, and the windward surface of the protrusion is configured as the third airflow guide D41.

[0108] Referring to Figure 15, in some embodiments, a support portion D42 may also be provided inside the air inlet channel D4. This support portion D42 is supported on the leeward side of the third guide portion D41 to strengthen the structure of the third guide portion D41 and improve the reliability of the third guide portion D41 in use.

[0109] In some embodiments, the support portion D42 can be a plate, which can be integrally formed and connected to the third side to have sufficient support strength. In other embodiments, the support portion D42 can also be a block, which is integrally formed at the bottom of the air inlet channel D4, and there is no limitation thereto.

[0110] Referring to Figure 2, the housing 1 includes a first housing 11 and a second housing 12 connected together. When the first housing 11 and the second housing 12 are assembled, they cooperate to form a receiving cavity for loading the components of the drying module D. The first housing 11 is assembled below the second housing 12. According to an embodiment of this disclosure, the moisture absorption channel D2, the moisture exhaust channel D3, the condensation cavity 2, the moisture exhaust fan cavity D5, the heat exchange cavity D6, the air inlet channel D4, and the circulating fan cavity D7 are all integrally formed on the first housing 11. The tops of the moisture absorption channel D2, the moisture exhaust channel D3, the condensation cavity 2, the moisture exhaust fan cavity D5, the heat exchange cavity D6, and the air inlet channel D4 can all be open. When the second housing 12 is assembled on the first housing 11, the second housing 12 seals the open tops of the moisture absorption channel D2, the moisture exhaust channel D3, the condensation cavity 2, the moisture exhaust fan cavity D5, the heat exchange cavity D6, and the air inlet channel D4. According to another embodiment of this disclosure, the moisture absorption channel D2, moisture exhaust channel D3, condensation cavity 2, moisture exhaust fan cavity D5, heat exchange cavity D6, and air inlet channel D4 may also be constructed independently of the first housing 11 or the second housing 12, and no limitation is made herein.

[0111] Referring to Figures 5 and 16 to 18, in some embodiments, the drying module D further includes a disc 6 and an air inlet pipe 7. The disc 6 is disposed within the housing 1. The disc 6 has the function of absorbing and dehumidifying; during rotation, the disc 6 absorbs moisture from the absorbent airflow and discharges the absorbed moisture through the dehumidifying airflow. The housing 1 is provided with an air outlet 8, which is connected to the air inlet pipe 7 for outputting the airflow within the housing 1 through the air inlet pipe 7. The air outlet 8 is provided with a first guide wall 81 for guiding the airflow. The first guide wall 81 is disposed near the disc 6, and at least a portion of the first guide wall 81 is provided with a buffer portion 811 to lift the airflow entering the air outlet 8, thereby buffering the airflow to a certain extent to avoid the formation of eddies when the airflow enters the air inlet pipe 7 and the accumulation of airflow at the connection transition between the housing 1 and the air inlet pipe 7, thus improving the airflow output and increasing the drying efficiency of the objects.

[0112] In related technologies, the air inlet end of the air inlet pipe of the drying module is connected to the air outlet of the shell. The radial angle between the air inlet pipe and the disc inside the shell is an obtuse angle, which makes it easy for the airflow to form vortices when entering the air inlet pipe. This causes the airflow to accumulate at the connection and transition between the shell and the air inlet pipe, affecting the output of the airflow and also affecting the drying efficiency of the objects.

[0113] Compared to the aforementioned related technologies, the drying module D provided according to one or more embodiments of this disclosure has an air outlet 8 provided in the housing 1, which is connected to the air inlet pipe 7. The air outlet 8 is provided with a first guide wall 81 for guiding airflow. Since the first guide wall 81 is located close to the wheel 6, at least a portion of the first guide wall 81 is provided with a buffer portion 811 for lifting the airflow, so as to buffer the airflow to a certain extent, so as to avoid the formation of vortices when the airflow enters the air inlet pipe 7, and the phenomenon of airflow accumulating at the connection transition between the housing 1 and the air inlet pipe 7, thereby improving the output of airflow and increasing the drying efficiency of the object.

[0114] In some embodiments, the buffer section 811 may be arranged parallel to or at an angle to the radial direction of the disc 6. At least a portion of the top of the buffer section 811 may be higher than the bottom of the disc 6. The airflow generated from the disc 6 can be lifted by the buffer section 811 and then enter the air outlet section 8 and the air inlet pipe 7 to buffer the airflow and improve the airflow output, thereby increasing the drying efficiency of the object.

[0115] Referring to Figures 5 and 18, according to certain embodiments of this disclosure, the direction of the airflow flowing on the buffer section 811 is arranged at an angle to the radial direction of the wheel 6, thereby lifting the airflow generated inside the housing 1. Because the direction of the airflow flowing on the buffer section 811 is arranged at an angle to the radial direction of the wheel 6, the airflow can be buffered to a certain extent to avoid the formation of vortices when the airflow enters the air intake pipe 7, and to prevent airflow accumulation at the connection transition between the housing 1 and the air intake pipe 7, thereby improving airflow output and increasing the drying efficiency of the object.

[0116] Referring to Figures 18 to 22, according to certain embodiments of this disclosure, the first guide wall 81 may further include a transition portion 812, with both ends of the transition portion 812 connected to the buffer portion 811 and the air intake pipe 7, respectively. The transition portion 812 and the wheel 6 are arranged radially parallel or nearly parallel. According to another embodiment of this disclosure, the buffer portion 811 may also be directly connected to the air intake pipe 7, without the aforementioned transition portion 812.

[0117] Referring to Figures 18 to 22, in some embodiments, the air outlet 8 is provided with a second guide wall 82 for guiding airflow. The second guide wall 82 is disposed away from the wheel 6, and is disposed opposite to the first guide wall 81. The second guide wall 82 is parallel or nearly parallel to the radial direction of the wheel 6. The second guide wall 82 can restrict the flow direction of the airflow to guide the airflow from the air outlet 8 of the housing 1 to the air inlet pipe 7.

[0118] Referring to Figures 16 to 18, in some embodiments, the housing 1 includes a first housing 11 and a second housing 12, which are connected to form a hollow structure. The first housing 11 is disposed above the second housing 12, and the second housing 12 has a receiving cavity 13 for accommodating the wheel 6. The air outlet 8 of the housing 1 is disposed within the first housing 11, and the edge of the second housing 12 is disposed at the inlet of the air outlet 8 of the housing 1.

[0119] Referring to Figures 23 and 24, in some embodiments, the first housing 11 is provided with an air outlet chamber 14, which communicates with the air inlet pipe 7. The bottom of the air outlet chamber 14 may have an opening 15. The buffer portion 811 of the aforementioned first guide wall 81 is provided on the second housing 12 and extends to the bottom of the air outlet chamber 14 to seal the opening 15 at the bottom of the air outlet chamber 14, thereby forming the air outlet portion 8 of the aforementioned housing 1. The air outlet portion 8 guides the airflow to the air outlet chamber 14 and then to the appropriate location via the air inlet pipe 7.

[0120] Referring to Figure 24, in some embodiments, the buffer portion 811 of the first guide wall 81 can extend from the edge of the receiving cavity 13 of the second housing 12 to the bottom of the exhaust cavity 14, which can be achieved by raising this portion of the second housing 12. The transition portion 812 of the first guide wall 81 can be connected to the bottom of the exhaust cavity 14, that is, the transition portion 812 and the buffer portion 811 are separately disposed. When the first housing 11 and the second housing 12 are assembled together, the transition portion 812 and the buffer portion 811 abut against each other to form the first guide wall 81.

[0121] In some embodiments, the buffer portion 811 and the transition portion 812 can be integrally formed to form a first guide wall 81, which can be achieved by raising this portion of the second housing 12. In other embodiments, the transition portion 812 of the first guide wall 81 can be disposed at the bottom of the air outlet cavity 14, with the buffer portion 811 and the transition portion 812 abutting to form the aforementioned first guide wall 81, while the second guide wall 82 can be integrally disposed at the top of the air outlet cavity 14.

[0122] According to a third aspect of the present disclosure, an electrical device is also provided, which includes the drying module D of the second aspect embodiment described above.

[0123] The electrical equipment with the aforementioned drying module D not only simplifies the piping connecting to the condenser 3 of the drying module D to improve production and assembly efficiency, but also allows the exhaust fan D37 to be connected to the exhaust channel D3 using the internal structure of the housing 1 of the drying module D, and achieves airtightness without the need for sealing components. The structure is simple and compact, which is beneficial for production and assembly.

[0124] In some embodiments, the electrical appliance can be a clothing handling device, such as a dryer or a washer-dryer combo. In other embodiments, the electrical appliance can also be other electrical appliances with drying functions, such as a sterilizer or a dishwasher, etc., and there is no limitation herein.

[0125] According to a fourth aspect of this disclosure, another drying module D is provided. Referring to Figures 2 and 3, the drying module D includes a housing 1, the aforementioned condenser assembly C, and an exhaust fan D37. The housing 1 is provided with an exhaust channel D3 and an exhaust fan cavity D5. The aforementioned condenser assembly C is disposed within the housing 1. The exhaust channel D3, the condenser cavity 2, and the exhaust fan cavity D5 are sequentially connected. The exhaust fan D37 is connected to the exhaust fan cavity D5, so that the exhaust airflow generated within the housing 1 is led out through the exhaust channel D3 to the condenser 3, whereby the exhaust airflow is condensed into cooling water and discharged through the drain outlet 21.

[0126] The drying module D provided according to the fourth aspect embodiment of this disclosure simplifies the piping connection with the condenser assembly C, improving production assembly efficiency. Furthermore, since the dehumidification channel D3, the condenser 3, and the dehumidification fan cavity D5 for assembling the dehumidification fan D37 are all housed within the housing 1, the dehumidification fan D37 can be connected to the dehumidification channel D3 using the internal structure of the housing 1, achieving airtightness without the need for seals. This results in a simple and compact structure, facilitating production assembly.

[0127] It should be noted that the condenser component C of the drying module D can also adopt the technical solution in the related technology where the condensate and the generated cooling water of the condenser 3 are discharged through corresponding pipelines, or other types of solutions can be adopted, without limitation. The drying module D of this disclosure will be further described below with reference to Figures 2 and 5-6.

[0128] Referring to Figures 5 and 6, the housing 1 is provided with a heat exchange chamber D6 for loading the disc module D1. A heating zone D61 is provided within the heat exchange chamber D6, and a heating element (not shown in the figures) is provided within the heating zone D61. The inlet end of the dehumidification channel D3 is connected to the edge of the heating zone D61. When the hygroscopic airflow passes through the disc module D1, the moisture in the hygroscopic airflow is absorbed by the disc module D1 and heated by the heating element to generate a dry airflow. This dry airflow is conveyed to the roller R to remove moisture from the roller R. Simultaneously with the generation of the dry airflow, dehumidified air is generated within the heating zone D61. The dehumidification fan D37 is activated, and the dehumidified air is drawn out through the dehumidification channel D3, thus forming the aforementioned dehumidified airflow within the dehumidification channel D3.

[0129] Referring to Figures 5 and 6, the bottom of the condensation chamber 2 is lower than the outlet end of the dehumidification channel D3 to prevent condensate from overflowing onto the moisture-absorbing turntable inside the housing 1 in case of abnormal condensate discharge, thus affecting the moisture absorption and dehumidification effect of the drying module D. In some embodiments, the part of the bottom of the housing 1 where the condensation chamber 2 is located can be appropriately lowered, or the bottom of the dehumidification channel D3 can be appropriately raised.

[0130] Referring to Figures 5 and 6, a first guide section D31 is provided on the side of the outlet end of the dehumidification channel D3 facing the condenser cavity. The first guide section D31 is connected to the bottom of the air inlet 22 and descends sequentially along the airflow direction of the dehumidification airflow. That is, the first guide section D31 is used to guide the dehumidification airflow from the dehumidification channel D3 to the condenser 3 located in the condenser cavity 2. The first guide section D31 can be an inclined surface, an arc surface, or a combination of an inclined surface and an arc surface; no limitation is made here.

[0131] Referring to Figures 5 and 6, the dehumidification channel D3 has a first side portion D32 and a second side portion D33. The first side portion D32 is connected to one side of the air inlet 22, and a support portion 27 extending into the air inlet 22 is provided on the other side of the air inlet 22. The second side portion D33 is connected to the support portion 27 through a second guide portion D36. In some embodiments, the support portion 27 can be a plate disposed on the other side of the air inlet 22, which can be integrally formed with the side wall of the condenser cavity 2. The second guide portion D36 can be a plate integrally formed and connected to the second side portion D33 of the dehumidification channel D3 to guide the outward direction of the dehumidification airflow. In addition, the extended support portion 27 can also restrict the displacement of the condenser 3 to prevent the vibration generated by the electrical equipment during operation from causing the condenser 3 to detach from the support block, thereby ensuring the normal operation of the condenser 3.

[0132] Referring to Figures 5 and 6, the cross-sectional dimension of the outlet end of the dehumidification channel D3 is smaller than the cross-sectional dimension of the rest of the dehumidification channel D3, so that the size of the outlet end of the dehumidification channel D3 is reduced, so that the dehumidification airflow can flow out to the condensation chamber 2 more quickly, thereby improving the condensation efficiency.

[0133] Referring to Figures 5 and 6, according to one embodiment of this disclosure, the first side portion D32 and the second side portion D33, along with the edge of the heating region D61, are configured as the inlet end of the first dehumidification channel D3. The portion of the first side portion D32 opposite to the portion of the second guide portion D36, and the portion of the second guide portion D36 opposite to the second guide portion D36, are configured as the outlet end of the first dehumidification channel D3. The cross-sectional dimension of the dehumidification channel D3 gradually decreases from the inlet end to the outlet end, thereby reducing the size of the outlet end of the dehumidification channel D3 and accelerating the flow of the dehumidified airflow to the condensing cavity 2, thus improving the condensation efficiency. According to another embodiment of this disclosure, only the cross-sectional dimension of the outlet end of the first dehumidification channel D3 may be reduced, which also accelerates the flow of the dehumidified airflow to the condensing cavity 2.

[0134] Referring to Figures 5 and 6, the side wall of the condensing cavity 2 can also be provided with an air outlet 26, which is connected to the dehumidification fan cavity D5, so that the dehumidification airflow can be drawn into the condensing cavity 2 when the dehumidification fan D37 is working.

[0135] Referring to Figures 5 and 6, according to one embodiment of this disclosure, the air outlet 26 and the air inlet 22 are respectively disposed on two adjacent side walls of the condensing cavity 2 to make the structure compact and reduce the size occupied by the drying module D. According to another embodiment of this disclosure, the air outlet 26 and the air inlet 22 may also be respectively disposed on two opposite side walls of the condensing cavity 2.

[0136] Referring to Figure 6, the bottom of the dehumidification fan cavity D5 is higher than the bottom of the condensation cavity 2 to prevent condensate from overflowing into the dehumidification fan cavity D5 inside the housing 1 and affecting the normal operation of the dehumidification fan D37 in case of abnormal condensate discharge.

[0137] According to one embodiment of this disclosure, the bottom of the first guide section D31 can have a height difference with the bottom of the condensing cavity 2. Since the bottom of the dehumidification fan cavity D5 and the bottom of the condensing cavity 2 also have a height difference, the bottom of the condensing cavity 2 can form a circumferentially closed cavity to receive the cooling water generated by the condenser 3. According to another embodiment of this disclosure, the bottom of the first guide section D31 can also be at the same height as the bottom of the dehumidification fan cavity D5, as long as the inlet end of the condensing cavity 2 is higher than the bottom of the dehumidification channel D3.

[0138] Referring to Figure 2, the housing 1 includes a first housing 11 and a second housing 12 connected together. When the first housing 11 and the second housing 12 are assembled, they cooperate to form a receiving cavity for loading the drying module D component. According to one embodiment of this disclosure, at least a portion of the aforementioned moisture absorption channel D2, moisture exhaust channel D3, condensation cavity 2, moisture exhaust fan cavity D5, heat exchange cavity D6, and air inlet channel D4 can be constructed from the first housing 11 and the second housing 12. According to another embodiment of this disclosure, the aforementioned moisture absorption channel D2, moisture exhaust channel D3, condensation cavity 2, moisture exhaust fan cavity D5, heat exchange cavity D6, and air inlet channel D4 can also be constructed from either the first housing 11 or the second housing 12 alone, without limitation.

[0139] According to the fifth aspect of this disclosure, another electrical device is also provided, which includes the drying module D of the fourth aspect embodiment described above.

[0140] The electrical equipment with the aforementioned drying module D not only simplifies the piping connecting to the condenser 3 of the drying module D to improve production and assembly efficiency, but also allows the exhaust fan D37 to be connected to the exhaust channel D3 using the internal structure of the housing 1 of the drying module D, and achieves airtightness without the need for sealing components. The structure is simple and compact, which is beneficial for production and assembly.

[0141] In some embodiments, the electrical appliance can be a clothing handling device, such as a dryer or a washer-dryer combo. In other embodiments, the electrical appliance can also be other electrical appliances with drying functions, such as a sterilizer or a dishwasher, etc., and there is no limitation herein.

[0142] In related technologies, the air inlet end of the air inlet pipe of the drying module is connected to the air outlet of the shell. The radial angle between the air inlet pipe and the disc inside the shell is an obtuse angle, which makes it easy for the airflow to form vortices when entering the air inlet pipe. This causes the airflow to accumulate at the connection and transition between the shell and the air inlet pipe, affecting the output of the airflow and also affecting the drying efficiency of the objects.

[0143] Based on the aforementioned technical problems, according to the sixth aspect of this disclosure, a drying module is provided, which aims to at least partially solve the technical problem of airflow accumulation at the connection transition between the housing 1 and the air inlet channel, affecting the output of airflow, so as to improve the drying efficiency of clothes.

[0144] Figure 16 shows a structural schematic diagram of the drying module in some embodiments, Figure 17 shows a cross-sectional schematic diagram of the drying module and the air inlet pipe according to an embodiment of the present disclosure, and Figure 18 shows a cross-sectional schematic diagram of the drying module and the air inlet pipe according to another embodiment of the present disclosure. Referring to Figures 16-18, the drying module provided by the present disclosure includes a housing 1, a wheel 6, and an air inlet pipe 7. The wheel 6 is disposed within the housing 1, and the housing 1 is provided with an air outlet 8. The air outlet 8 of the housing 1 is connected to the air inlet pipe 7 for outputting airflow from the housing 1 through the air inlet pipe 7. The air outlet 8 is provided with a first guide wall 81 for guiding airflow. The first guide wall 81 is disposed near the wheel 6, and at least a portion of the first guide wall 81 is provided with a buffer portion 811 to lift the airflow entering the air outlet 8, thereby buffering the airflow to a certain extent to avoid the formation of eddies when the airflow enters the air inlet pipe 7 and the accumulation of airflow at the connection transition between the housing 1 and the air inlet pipe 7, thus improving the airflow output and increasing the drying efficiency of the object.

[0145] Referring to Figure 17, according to an embodiment of the present disclosure, the buffer section 811 may be parallel to the radial direction of the wheel 6. At least a portion of the top of the buffer section 811 is higher than the bottom of the wheel 6. The airflow generated from the wheel 6 can be lifted by the guidance of the buffer section 811 and then enter the air outlet section 8 and the air inlet pipe 7 to buffer the airflow and improve the airflow output, thereby improving the drying efficiency of the object.

[0146] Referring to Figure 17, the wheel 6 is arranged horizontally or nearly horizontally. The top of the buffer section 811 can be a plane, which can be slightly lower than the top of the wheel 6. This is to maximize the airflow while ensuring the airflow area entering the air outlet section 8, thereby improving airflow output and increasing the drying efficiency of the objects. In other embodiments, the top of the buffer section 811 can also be flush with the top of the wheel 6, or slightly higher than the top of the wheel 6; this is not a limitation.

[0147] Referring to Figure 18, according to another embodiment of this disclosure, the direction of the airflow flowing on the buffer section 811 is arranged at an angle to the radial direction of the wheel 6, so as to lift the airflow generated inside the housing 1. This can buffer the airflow to a certain extent to avoid the formation of turbulence when the airflow enters the air intake pipe, and to prevent the airflow from accumulating at the connection transition between the housing and the air intake pipe, thereby improving the airflow output and increasing the drying efficiency of the object.

[0148] Referring to Figure 18, according to an embodiment of this disclosure, at least a portion of the buffer section 811 is an inclined surface 811a, and the angle between the inclined surface 811a and the radial direction of the disc 6 is between 5 and 20°, for example, 5°, 10°, or 20°. If the angle between the inclined surface 811a and the radial direction of the disc 6 is too large, the airflow will be deflected too much when entering the exhaust section 8, easily causing vortices to form when the airflow enters the exhaust section 8; if the angle is too small, it will not buffer the airflow. Therefore, this disclosure sets the angle between the inclined surface 811a and the radial direction of the disc 6 between 5 and 20° to achieve the technical objective of buffering the airflow, avoiding vortex generation, and improving drying efficiency.

[0149] According to another embodiment of this disclosure, at least a portion of the buffer section 811 can be an arc surface 811b to elevate the airflow generated within the housing 1, making the airflow smoother. Figure 20 shows a schematic diagram of the connection between the air outlet and the air inlet pipe of the drying module when the buffer section is an arc surface. Referring to Figure 20, the angle between the tangent at the midpoint of the arc surface 811b and the radial direction of the wheel 6 is between 5 and 20°. The reason for setting the angle can be referred to the description above, and will not be repeated here.

[0150] Figures 21 and 22 show schematic diagrams of the connection between the air outlet and the air inlet pipe of the drying module when the buffer section is a combination of an arc surface and a slope. Referring to Figures 21 and 22, in some embodiments, the buffer section 811 may include a slope 811a and an arc surface 811b, with the slope 811a and arc surface 811b extending sequentially toward the air inlet pipe 7 (as shown in Figure 21), or the arc surface 811b and slope 811a extending sequentially toward the air inlet pipe 7 (as shown in Figure 22), to enhance the airflow generated within the housing 1, making the airflow smoother. In some embodiments, the angle between the slope 811a and the radial direction of the wheel 6 is between 5 and 20°, and the angle between the tangent at the midpoint of the arc surface 811b and the radial direction of the wheel 6 is between 5 and 20°. The reason for this angle setting can be referred to the description above, and will not be repeated here.

[0151] Referring to Figures 18-22, according to an embodiment of the present disclosure, the first guide wall 81 may further include a transition section 812, the two ends of which are connected to the buffer section 811 and the air intake pipe 7, respectively, and the transition section 812 and the wheel 6 are arranged in parallel or nearly parallel radially.

[0153] Referring to Figures 18-22, in some embodiments, the air outlet 8 is provided with a second guide wall 82 for guiding airflow. The second guide wall 82 is disposed away from the wheel 6, and is disposed opposite to the first guide wall 81. The second guide wall 82 is parallel or nearly parallel to the radial direction of the wheel 6. The second guide wall 82 can restrict the flow direction of the airflow to guide the airflow from the air outlet 8 of the housing 1 to the air inlet pipe 7.

[0154] Referring to Figures 16-18, the housing 1 includes a first housing 11 and a second housing 12, which are connected to form a hollow structure. The first housing 11 is positioned above the second housing 12. The second housing 12 contains a cavity 13 for accommodating the dehumidifying wheel 6. The air outlet 8 of the housing 1 is located within the first housing 11, and the edge of the second housing 12 is positioned at the inlet of the air outlet 8. To achieve the aforementioned buffer section 811, the structure of the housing 1 has also been improved in this disclosure.

[0155] Figure 23 shows a schematic diagram of the first housing in Figure 16, and Figure 24 shows a schematic diagram of the second housing in Figure 16. Referring to Figures 16-18 and 23-24, the first housing 11 is provided with an air outlet chamber 14, which is connected to the air inlet pipe 7. The bottom of the air outlet chamber 14 may have an opening 15. The buffer portion 811 of the aforementioned first guide wall 81 is disposed on the second housing 12 and extends to the bottom of the air outlet chamber 14 to seal the opening 15 at the bottom of the air outlet chamber 14, forming the air outlet portion 8 of the aforementioned housing 1, so as to guide the airflow to the air outlet chamber 14 and then to the appropriate location through the air inlet pipe 7.

[0156] Referring to Figure 24, in some embodiments, the buffer portion 811 of the first guide wall 81 can extend from the edge of the receiving cavity 13 of the second housing 12 to the bottom of the exhaust cavity 14, achieved by raising this portion of the second housing 12. The transition portion 812 of the first guide wall 81 can be connected to the bottom of the exhaust cavity 14, that is, the transition portion 812 and the buffer portion 811 are separately disposed, and when the first housing 11 and the second housing 12 are assembled together, the transition portion 812 and the buffer portion 811 abut against each other to form the first guide wall 81.

[0157] According to one embodiment of the present disclosure, the buffer portion 811 and the transition portion 812 can be integrally formed to form a first flow guide wall 81, which can be achieved by raising this portion of the second housing 12.

[0158] In addition, the transition portion 812 of the first guide wall 81 can be disposed at the bottom of the air outlet cavity 14, and the buffer portion 811 and the transition portion 812 are connected to form the first guide wall 81, while the second guide wall 82 can be disposed as a whole at the top of the air outlet cavity 14.
