Description

Technical Field

[0001] This disclosure relates to the field of clothing processing equipment technology, and more specifically, to a clothing processing device. Background Technology

[0002] In related technologies, the drying unit in a washing machine is the core system for achieving the function of drying clothes. Its role is to quickly remove moisture from clothes through heat circulation, air flow, and humidity control. For multi-drum clothing processing equipment, the limited internal space poses challenges to the placement of the drying unit. Utility Model Content

[0003] The purpose of this disclosure is to provide a garment processing apparatus in which the drying component can be arranged in a small space to at least partially solve the problems in the related art.

[0004] To overcome the problems existing in related technologies, a first aspect of this disclosure provides a garment processing device, comprising: a housing; a first cylindrical body disposed within the housing; two second cylindrical bodies disposed within the housing, respectively located above the side of the first cylindrical body and on opposite sides of a vertical plane containing the central axis of the first cylindrical body, wherein the diameter of the second cylindrical bodies is smaller than the diameter of the first cylindrical body; and a drying assembly for drying the first cylindrical body, comprising an evaporator and a condenser, the evaporator and the condenser being located between the first cylindrical body and the second cylindrical bodies. Thus, by arranging the evaporator and condenser in the drying assembly between the first and second cylindrical bodies, the drying assembly can be arranged in a multi-cylinder garment processing device within a confined space by utilizing the vertical gap between the first and second cylindrical bodies.

[0005] In some possible implementations, the evaporator and the condenser are located in the middle of the housing. Thus, by placing the evaporator and the condenser in the middle of the housing, the space between the first and second cylinders and in the front-rear direction of the first cylinder can be utilized, making the structure of the garment processing equipment more compact. Furthermore, it can balance the overall center of gravity of the garment processing equipment, reduce overall eccentric vibration, and improve the stability of the garment processing equipment.

[0006] In some possible implementations, at least part of the condenser is located on one side of the vertical plane containing the central axis of the first cylinder, and the evaporator is located on the other side of the vertical plane containing the central axis of the first cylinder. Thus, by utilizing the circumferential space of the first cylinder, the condenser and evaporator in the drying assembly are arranged between the first and second cylinders, which not only makes the structure of the clothing processing equipment more compact but also balances the weight distribution of the clothing processing equipment on both sides of the circumference of the first cylinder, suppressing vibration of the clothing processing equipment.

[0007] In some possible implementations, the evaporator and the condenser are positioned near the door seal of the first cylinder. Thus, the fan in the garment processing equipment is typically located behind the first cylinder. By positioning the evaporator and condenser near the door seal of the first cylinder, the space in the front-rear direction of the first cylinder can be fully utilized, while simultaneously balancing the weight distribution of the garment processing equipment in the front-rear direction, reducing eccentric vibrations caused by uneven weight distribution in this direction.

[0008] In some possible implementations, the drying assembly further includes a fan and a drying tunnel; the air inlet of the fan is connected to the first drum, one end of the drying tunnel is connected to the air outlet of the fan, and the other end of the drying tunnel is connected to the air inlet of the first drum; the evaporator and the condenser are disposed inside the drying tunnel, with the evaporator arranged close to the fan. Thus, by placing the evaporator and condenser inside the drying tunnel, and with the evaporator close to the fan, the fan can be activated to guide the humid, hot air from the first drum into the drying tunnel, where it passes through the evaporator and condenser. After being processed by the evaporator and condenser, the resulting dry, hot air enters the first drum to dry the clothes.

[0009] In some possible implementations, in a plane perpendicular to the air inlet direction of the drying duct, the ratio K1 of the projected area of ​​the evaporator to the projected area of ​​the drying duct satisfies: 0.65 ≤ K1 ≤ 1.5; and / or in a plane perpendicular to the air inlet direction of the drying duct, the ratio K2 of the projected area of ​​the condenser to the projected area of ​​the drying duct satisfies: 0.65 ≤ K2 ≤ 1.5. Thus, by maintaining the ratio K1 (0.65 ≤ K1 ≤ 1.5) and / or the ratio K2 (0.65 ≤ K2 ≤ 1.5), the condenser and evaporator can be adapted to clothing processing equipment with different drying requirements. Through the synergistic effect of the condenser and evaporator, humid air can be efficiently processed into dry air.

[0010] In some possible implementations, the distance H1 between the upper side of the drying tunnel and the top surface of the housing satisfies: 300mm ≤ H1 ≤ 400mm; and / or the distance H2 between the lower side of the drying tunnel and the bottom surface of the housing satisfies: 600mm ≤ H2 ≤ 850mm; and / or the height H3 of the drying tunnel satisfies: 60mm ≤ H3 ≤ 150mm. Thus, when the garment processing equipment is in a standard or non-standard housing, by limiting the distance H1 between the upper side of the drying tunnel and the top surface of the housing, the distance H2 between the lower side of the drying tunnel and the bottom surface of the housing, and the height H3 of the drying tunnel, the drying tunnel can be arranged within a limited space in the garment processing equipment.

[0011] In some possible implementations, the drying duct extends from one side of the vertical plane containing the central axis of the first cylinder to the other side. An air inlet communicating with the air outlet of the fan is located at the rear of the drying duct, and an air outlet communicating with the air inlet at the door seal of the first cylinder is located at the front of the drying duct. Thus, by extending the drying duct from one side of the vertical plane containing the central axis of the first cylinder to the other side, it is convenient to arrange the drying duct between the first and second cylinders, and to facilitate communication with the air outlet and air inlet of the first cylinder, thereby creating hot, dry air within the drying duct to dry the clothes inside the first cylinder.

[0012] In some possible implementations, the garment processing equipment further includes a compressor located behind the drying tunnel; the compressor and the fan are respectively located on opposite sides of the central axis of the first cylinder. Thus, by placing the compressor behind the drying tunnel, the space within the garment processing equipment in the front-to-back direction can be utilized. Furthermore, placing the compressor behind the drying tunnel also helps to balance the weight distribution of the garment processing equipment in the front-to-back direction. The compressor and the fan being located on opposite sides of the central axis of the first cylinder allows for the utilization of the space within the garment processing equipment housing in the circumferential direction of the first cylinder. Additionally, it helps to balance the weight distribution of the garment processing equipment in the circumferential direction of the first cylinder, thereby improving the stability of the garment processing equipment.

[0013] In some possible implementations, a filter assembly is provided within the drying tunnel, located between the evaporator and the air inlet of the drying tunnel. This filter assembly filters out hot, humid air, reducing the likelihood of clothing debris clogging the condenser or scratching the heat exchange surfaces, thus minimizing the impact on the condenser's heat exchange efficiency and shortening the equipment's lifespan.

[0014] In some possible implementations, the sidewalls of the drying tunnel have openings for installing and removing the filter assembly, which is detachably installed inside the drying tunnel. This detachable installation of the filter assembly inside the drying tunnel facilitates its replacement, preventing filter clogging from affecting hot air circulation and thus the efficiency of the condenser and evaporator.

[0015] In some possible implementations, the evaporator and the condenser are tubular structures. This tubular structure allows for efficient handling of humid air, enabling the humid air to pass through the evaporator and condenser to form dry, hot air for drying the clothes inside the first drum.

[0016] The above technical solution involves setting a first cylinder and two second cylinders inside the garment processing equipment, and placing the evaporator and condenser of the drying component between the first and second cylinders. This allows the drying component to be arranged in a multi-cylinder garment processing equipment within a small space by utilizing the vertical gap between the first and second cylinders.

[0017] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0026] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0027] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "front," and "back" are used based on the definition of garment handling equipment, which can be found in the following references. Figure 1 In the context of clothing processing equipment, the terms "up," "down," "front," and "back" refer to the direction of gravity. "Up" can be understood as the direction of gravity of the equipment, while "front" refers to the side of the equipment facing the user, and "back" to the side away from the user. The gate of the clothing processing equipment is typically located at the front. "Inner" and "outer" refer to the inner and outer contours of each component. The terms "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Furthermore, in the following description, when referring to accompanying drawings, the same reference numerals in different drawings denote the same or similar elements, which will not be repeated here.

[0028] The inventors discovered that the limited internal space of multi-tube clothing processing equipment makes it difficult to arrange the drying components.

[0029] To solve the above technical problems, such as Figures 1 to 6 As shown, this disclosure provides a garment processing device, including: a housing 100, a first cylindrical body 1, two second cylindrical bodies 2, and a drying assembly 3; the first cylindrical body 1 is disposed inside the housing 100; the two second cylindrical bodies 2 are disposed inside the housing 100, respectively located above the side of the first cylindrical body 1, and located on opposite sides of the vertical plane M where the central axis A1 of the first cylindrical body 1 is located, wherein the diameter of the second cylindrical body 2 is smaller than the diameter of the first cylindrical body 1; the drying assembly 3 is used for drying the first cylindrical body 1, and the drying assembly 3 includes an evaporator 31 and a condenser 32, the evaporator 31 and the condenser 32 being located between the first cylindrical body 1 and the second cylindrical bodies 2.

[0030] Through the above technical solution, a first cylinder 1 and two second cylinders 2 are arranged inside the housing 100 of the clothing processing equipment, and the evaporator 31 and condenser 32 of the drying component 3 are arranged between the first cylinder 1 and the second cylinder 2. Thus, the drying component 3 can be arranged in the multi-cylinder clothing processing equipment by utilizing the gap between the first cylinder 1 and the second cylinder 2 in the vertical direction in a narrow space.

[0031] In one exemplary application scenario, such as Figure 1 , Figure 2 and Figure 6As shown, the garment processing equipment can be a washer-dryer combo. Both the first drum 1 and the two second drums 2 can be constructed as washing drums. The diameter of the two second drums 2 is smaller than the diameter of the first drum 1. Thus, the first drum 1 is used for washing a large quantity of garments or large, heavy individual items, while the two second drums 2 are used for washing a smaller quantity of garments or small, light individual items. By setting the first drum 1 and the second drums 2, garments can be washed separately. Of course, the dimensions of the two second drums 2 can be the same or different, and can be selectively set according to specific operating conditions.

[0032] It is understandable that the first cylinder 1 and the two second cylinders 2 in the above-mentioned garment processing equipment can work independently to adapt to different garment processing conditions.

[0033] It should be noted that the first drum 1 and the two second drums 2 in the clothing processing equipment here both include an outer drum and an inner drum, wherein the inner drum can rotate relative to the outer drum for washing clothes.

[0034] The drying component 3 of the clothing processing equipment is used to process the humid and hot air in the first drum 1 to form dry and hot air, which is then used to dry the clothes in the first drum 1. That is, the air outlet of the first drum 1 is connected to the air inlet of the drying component 3, and the air inlet of the first drum 1 is connected to the air outlet of the drying component 3, so that the humid and hot air in the first drum 1 can circulate into the drying component 3 to form dry and hot air to dry the clothes in the first drum 1. In the drying assembly 3, the evaporator 31 is used when the refrigerant is in a gaseous state at low temperature and low pressure. The gaseous refrigerant exchanges heat with the humid air supplied by the first cylinder 1 flowing over the surface of the evaporator 31, thereby cooling the humid air below the dew point. Water vapor in the air condenses into liquid water and is discharged. The air after passing through the evaporator 31 becomes dry. The refrigerant can be tetrafluoroethane. The condenser 32 in the drying assembly 3 is used when the high-temperature, high-pressure gaseous refrigerant releases heat to the air after passing through the evaporator 31. At this time, the refrigerant condenses into a liquid state, and the air after passing through the condenser 32 becomes dry, hot air. This dry, hot air enters the first cylinder 1 through the air inlet to dry the clothes inside. The flow direction of the humid, hot air can be referenced... Figure 3 and Figure 5 The direction of the dashed arrow.

[0035] It is understandable that the humid air supplied by the first cylinder 1 can first pass through the evaporator 31 and then through the condenser 32. In this case, the humid air first passes through the evaporator 31, where the water vapor in the humid air condenses into liquid water and is discharged. The dehumidified air then passes through the condenser 32 and is heated to form dry, hot air before circulating back into the first cylinder 1. Alternatively, the humid air supplied by the first cylinder 1 can also first pass through the condenser 32 and then through the evaporator 31. In this case, the air passing through the evaporator 31 needs to be heated by an additional heating element (heating wire) before re-entering the first cylinder 1. In this embodiment, the humid air supplied by the first cylinder 1 first passes through the evaporator 31 and then through the condenser 32 before entering the first cylinder 1 to dry the clothes.

[0036] In some feasible embodiments, in order to facilitate the circulation of hot and humid air in the first cylinder 1 into the drying assembly 3 for drying, the drying assembly 3 also includes a fan 33 and a drying duct 34. The air inlet of the fan 33 is connected to the first cylinder 1, one end of the drying duct 34 is connected to the air outlet of the fan 33, and the other end of the drying duct 34 is connected to the air inlet of the first cylinder 1. The evaporator 31 and the condenser 32 are located inside the drying duct 34, and the evaporator 31 is arranged close to the fan 33.

[0037] To ensure that the hot and humid air discharged from the first cylinder 1 can fully contact the drying assembly 3, the air outlet of the first cylinder 1 can be located at the rear of the first cylinder 1, and the air inlet of the first cylinder 1 can be located at the door seal 11 at the front of the first cylinder 1. In this way, by configuring the air outlet and air inlet on the first cylinder 1, the contact time between the hot and humid air and the drying assembly 3 can be extended, thereby enabling the hot and humid air to fully contact and exchange heat with the evaporator 31 and condenser 32 to form dry and hot air for drying the clothes inside the first cylinder 1.

[0038] Of course, in order to facilitate the extraction of the hot and humid air from the first cylinder 1 through the air outlet, the fan 33 is located at the rear of the first cylinder 1. The air outlet of the fan 33 is connected to one end of the drying tunnel 34, the air inlet of the fan 33 is connected to the air outlet of the first cylinder 1, and the other end of the drying tunnel 34 is connected to the air inlet of the first cylinder 1. Thus, by rotating the fan 33, the hot and humid air can be driven out from the air outlet of the first cylinder 1, and flow along the drying tunnel 34 and pass through the evaporator 31 and condenser 32 in sequence to form dry and hot air before re-entering the first cylinder 1 to dry the clothes.

[0039] In some possible implementations, such as Figure 3 and Figure 5As shown, the drying duct 34 extends from one side of the vertical plane M containing the central axis A1 of the first cylinder 1 to the other side of the vertical plane M containing the central axis A1 of the first cylinder 1. An air inlet connected to the air outlet of the fan 33 is located at the rear of the drying duct 34, and an air outlet connected to the air inlet at the door seal 11 of the first cylinder 1 is located at the front of the drying duct 34. Thus, by extending the drying duct 34 from one side of the vertical plane M containing the central axis A1 of the first cylinder 1 to the other side of the vertical plane M containing the central axis A1 of the first cylinder 1, the circumferential space of the first cylinder 1 is utilized to arrange the drying duct 34 between the first cylinder 1 and the second cylinder 2. This facilitates communication between the drying duct 34 and the air outlet at the front and the air inlet at the rear of the first cylinder 1. The longer drying duct 34 allows the humid and hot air discharged from the first cylinder 1 to fully contact the evaporator 31 and the condenser 32, thereby forming dry and hot air that then enters the first cylinder 1 to dry the clothes.

[0040] In some possible implementations, such as Figure 2 , Figure 3 and Figure 5 As shown, the garment processing equipment also includes a compressor 4, which is located behind the drying tunnel 34; the compressor 4 and the fan 33 are located on opposite sides of the central axis A1 of the first cylinder 1. In this embodiment, during the refrigerant circulation process, the low-temperature, low-pressure refrigerant enters the evaporator 31 and exchanges heat with the air discharged from the first cylinder 1. At this time, the refrigerant after passing through the evaporator 31 becomes a low-temperature, low-pressure gaseous state, the air cools down to below the dew point, and the water vapor in the air forms condensate and is discharged. The refrigerant enters the compressor 4, and the compressor 4 performs compression, compressing the low-temperature, low-pressure gaseous refrigerant after heat exchange in the evaporator 31, and the refrigerant becomes a high-temperature, high-pressure gaseous state. The high-temperature, high-pressure gaseous refrigerant enters the condenser 32 and exchanges heat with the air discharged from the first cylinder 1. At this time, the refrigerant after passing through the condenser 32 becomes a high-temperature, high-pressure liquid state after heat exchange. The air is heated and enters the first cylinder 1 to dry the clothes in the first cylinder 1. The high-temperature, high-pressure liquid refrigerant is throttled and depressurized by the electronic expansion valve, becoming a low-temperature, low-pressure gas-liquid mixed refrigerant. The low-temperature, low-pressure refrigerant then enters the evaporator 31 again to exchange heat with the air discharged from the first cylinder 1. This cycle repeats, thereby enabling the drying assembly 3 to cyclically dry the clothes in the first cylinder 1.

[0041] In some possible implementations, such as Figure 2 , Figure 3 and Figure 5As shown, the compressor 4 is located behind the drying tunnel 34, and the compressor 4 and the fan 33 are located on opposite sides of the central axis of the first cylinder 1. The compressor 4's location behind the drying tunnel 34 utilizes the space in the front-to-back direction of the housing 100, while simultaneously balancing the weight distribution of the garment processing equipment in the front-to-back direction, reducing vibrations caused by uneven weight distribution during operation. Furthermore, the compressor 4 and the fan 33's location on opposite sides of the central axis of the first cylinder 1 utilize the circumferential space of the first cylinder 1, while simultaneously balancing the weight distribution of the garment processing equipment in the circumferential direction, improving the overall stability of the garment processing equipment. Of course, the aforementioned position of the compressor 4 also facilitates its connection to the evaporator 31 and the condenser 32, enabling the compressor 4 to drive the refrigerant to complete circulation.

[0042] like Figures 1 to 6 As shown, in some possible embodiments, the evaporator 31 and condenser 32 are located in the middle of the housing 100. It is understood that the "middle of the housing 100" can refer to a position near the geometric center of the housing 100 or the geometric center itself. In this case, placing the evaporator 31 and condenser 32 in the middle of the housing 100, between the first cylinder 1 and the second cylinder 2, allows for full utilization of both vertical and longitudinal space, making the structure of the garment processing equipment more compact. Furthermore, placing the evaporator 31 and condenser 32 in the middle of the housing 100 also balances the overall weight distribution of the garment processing equipment, reducing vibrations caused by uneven weight distribution. Here, vertical space refers to the gap between the first cylinder 1 and the second cylinder 2 in the vertical direction of the housing 100 when the garment processing equipment is placed. Forward and longitudinal space refers to the direction in which the opening of the first cylinder 1 faces forward, and the direction away from the opening of the first cylinder 1 faces backward.

[0043] It is understandable that the motors used to drive the first cylinder 1 and the two second cylinders 2 in the aforementioned clothing processing equipment are typically located at the rear of the housing 100. In this case, placing the evaporator 31 and condenser 32 in the middle of the housing 100 allows for avoidance of other compatible components and facilitates their coordinated arrangement. Of course, in some possible embodiments, the evaporator 31 and condenser 32 are positioned near the door seal 11 of the first cylinder 1. In clothing processing equipment, the fan 33 is usually located behind the first cylinder 1. By placing the evaporator 31 and condenser 32 near the door seal 11 of the first cylinder 1, components located at the rear of the first cylinder 1, such as the motors driving the first cylinder 1 and the second cylinder 2, the fan 33, and the compressor 4, can be avoided. This makes full use of the space in the front-back direction of the first cylinder 1. In addition, it can balance the weight distribution of the clothing processing equipment in the front-back direction. The evaporator 31 and condenser 32 near the door seal 11 of the first cylinder 1 can be balanced with the compressor 4 and fan 33 at the rear, thereby improving the overall stability of the clothing processing equipment.

[0044] In some possible implementations, such as Figure 3 and Figure 5 As shown, at least part of the condenser 32 is located on one side of the vertical plane M where the central axis A1 of the first cylinder 1 is located, and the evaporator 31 is located on the other side of the vertical plane M where the central axis A1 of the first cylinder 1 is located. Therefore, the circumferential space of the first cylinder 1 can be fully utilized to arrange the condenser 32 and evaporator 31 in the drying assembly 3 between the first cylinder 1 and the second cylinder 2. Furthermore, the circumferential distribution of the condenser 32 and evaporator 31 in the first cylinder 1 can be balanced, improving the overall stability of the clothing processing equipment.

[0045] Of course, it is understood that the embodiment described above, in which at least part of the condenser 32 is located on one side of the vertical plane M where the central axis A1 of the first cylinder 1 is located, and the evaporator 31 is located on the other side of the vertical plane M where the central axis A1 of the first cylinder 1 is located, is illustrative. In other embodiments, for example, when other components need to be installed on one side of the vertical plane M where the central axis A1 of the first cylinder 1 is located, the condenser 32 and the evaporator 31 can also be located on the other side of the vertical plane M where the central axis A1 of the first cylinder 1 is located. Thus, the evaporator 31 and the condenser 32 can be flexibly arranged inside the housing 100, and their specific positions can be adjusted according to the positions of other components inside the housing 100 to accommodate the coordinated arrangement of multiple components inside the housing 100. Of course, arranging the evaporator 31 and the condenser 32 on both sides of the vertical plane M where the central axis A1 of the first cylinder 1 is located can also balance the weight distribution in the circumferential direction of the first cylinder 1 and improve the overall stability of the clothing processing equipment.

[0046] In some possible implementations, in order for the evaporator 31 and condenser 32 to have sufficient drying capacity to process humid and hot air into dry and hot air within a limited space, the ratio K1 of the projected area of ​​the evaporator 31 to the projected area of ​​the drying tunnel 34 in a plane perpendicular to the air inlet direction of the drying tunnel 34 satisfies: 0.65≤K1≤1.5; and / or the ratio K2 of the projected area of ​​the condenser 32 to the projected area of ​​the drying tunnel 34 in a plane perpendicular to the air inlet direction of the drying tunnel 34 satisfies: 0.65≤K2≤1.5. Thus, by setting the ratio K1 of the projected area of ​​the evaporator 31 to the projected area of ​​the drying tunnel 34 to 0.65≤K1≤1.5, and / or the ratio K2 of the projected area of ​​the condenser 32 to the projected area of ​​the drying tunnel 34 to 0.65≤K2≤1.5, it is possible to select different ratios K1 and K2 of the projected area of ​​the evaporator 31 to the projected area of ​​the drying tunnel 34 for different sizes of clothing processing equipment, so that the condenser 32 and the evaporator 31 have sufficient drying capacity to efficiently process humid and hot air into dry and hot air, thereby improving the drying efficiency of the first drum.

[0047] In some possible implementations, the distance H1 between the upper side of the drying tunnel 34 and the top surface of the chamber 100 satisfies: 300mm≤H1≤400mm; and / or the distance H2 between the lower side of the drying tunnel 34 and the bottom surface of the chamber 100 satisfies: 600mm≤H2≤850mm; and / or the height H3 of the drying tunnel 34 satisfies: 60mm≤H3≤150mm. Thus, by limiting the distance H1 between the upper side of the drying tunnel 34 and the top surface of the housing 100 (300mm≤H1≤400mm), the distance H2 between the lower side of the drying tunnel 34 and the bottom surface of the housing 100 (600mm≤H2≤850mm), and the height H3 of the drying tunnel 34 (60mm≤H3≤150mm), the appropriate distances H1 between the upper side of the drying tunnel 34 and the top surface of the housing 100, H2 between the lower side of the drying tunnel 34 and the bottom surface of the housing 100, and the height H3 of the drying tunnel 34 can be selected according to the specific size of the clothing processing equipment, whether the clothing processing equipment is in a standard or non-standard housing. This allows the drying tunnel 34 to be placed in the optimal installation position within the housing 100 of the clothing processing equipment. In this way, the drying tunnel 34 can be arranged within the limited space of the clothing processing equipment to efficiently dry the clothes in the first drum 1.

[0048] To reduce interference from clothing debris on the drying assembly 3, in some possible embodiments, a filter assembly 35 is provided inside the drying tunnel 34, located between the evaporator 31 and the air inlet of the drying tunnel 34. Thus, by placing the filter assembly 35 between the evaporator 31 and the air inlet of the drying tunnel 34, the humid air can come into contact with the filter assembly 35 immediately after being discharged from the first cylinder 1, thereby filtering the humid air in a timely manner. This reduces the risk of clothing debris clogging the evaporator 31 and / or condenser 32, or scratching the heat exchange surfaces of the evaporator 31 and / or condenser 32, thereby affecting the heat exchange efficiency of the condenser 32 and shortening the lifespan of the equipment.

[0049] Furthermore, in some possible embodiments, the sidewall of the drying tunnel 34 is formed with openings for installing and removing the filter assembly 35, which is detachably installed inside the drying tunnel 34. For example, the filter assembly 35 may include an outer frame and a filter 36. The outer frame may have protrusions that mate with the openings, and the outer frame is fixed in the drying tunnel 34 by snap-fit. In this way, the filter assembly can be detachably installed inside the drying tunnel 34, which facilitates the replacement or cleaning of the filter assembly 35 and prevents the filter 36 from becoming clogged, affecting the hot air circulation and the efficiency of the condenser 32 and evaporator 31. Of course, the filter assembly 35 may also include an outer frame and a filter 36. The outer frame has threaded holes that correspond one-to-one with the openings, and the outer frame can be fixedly connected to the drying tunnel 34 by screws, so that the filter assembly 35 can be placed between the air inlet of the evaporator 31 and the air inlet of the drying tunnel 34 to filter the hot and humid air discharged from the first cylinder 1 in a timely manner. It is understood that the aforementioned filter screen 36 can be a combination of stainless steel mesh, polyester retaining parts or wood pulp fiber filter paper, HEPA (High Efficiency Particulate Air Filter) filter element, etc. It is also understood that when the filter screen 36 uses a combination of multiple materials, the material with larger pores preferentially contacts the humid and hot air to form preliminary filtration. Then, the humid and hot air contacts the material with smaller pores to form further filtration. Thus, the combination of multiple materials enables the filter screen 36 to filter debris from the humid and hot air, preventing debris from clogging the condenser 32 and evaporator 31.

[0050] Of course, in order to facilitate the replacement of the filter assembly 35, an opening is provided on the front side of the housing 100. The filter assembly 35 is inserted into the preset position of the drying tunnel 34 through the opening and fixed to the drying tunnel 34 by means of a snap-fit ​​connection. When it needs to be replaced, the filter assembly 35 can be pulled out from the opening.

[0051] To facilitate heat exchange between the hot, humid air discharged from the first cylinder 1 and the corresponding evaporator 31 and condenser 32, in some possible embodiments, the evaporator 31 and condenser 32 are tubular. For example, the evaporator 31 can be a tubular evaporator, and the condenser 32 can be a tubular condenser. The tubular condenser and the tubular evaporator have a dense arrangement of tube bundles. Both the tubular condenser and the tubular evaporator can adopt a spiral flow channel to maximize the heat exchange area per unit volume, thereby efficiently exchanging heat with the hot, humid air. This allows the hot, humid air to form dry, hot air after passing through the tubular evaporator and the tubular condenser, which is then used to dry the clothes inside the first cylinder.
