Description

Technical Field

[0001] This invention relates to drum-type garment handling devices such as washer-dryer combos and dryers. Background Technology

[0002] In drum-type garment handling units, heat pump systems are increasingly being used to achieve the drying function due to their advantages such as energy saving and gentleness on clothing. In drum-type garment handling units equipped with heat pump systems, to improve drying efficiency and shorten drying time, it is advisable to increase the heat exchange area of ​​the heat pump system, specifically by increasing the airflow area of ​​the evaporator and condenser.

[0003] However, in previous drum-type garment processing devices, there was a lack of research on how to effectively guide the drying air towards the airflow side of the evaporator and condenser. In such cases, even if the airflow area of ​​the evaporator and condenser is increased, the effect on improving drying efficiency is very limited if the increased airflow area cannot be effectively utilized. Summary of the Invention

[0004] The problem the invention aims to solve

[0005] The present invention was made in view of the above-mentioned situation, and its object is to provide a drum-type garment processing device that can effectively utilize the windward area of ​​the drying device to improve drying efficiency.

[0006] Solution for solving the problem

[0007] To achieve the above objectives, the first technical solution of the present invention provides a drum-type clothing processing device, comprising: a housing; an outer groove supported within the housing; a drum rotatably mounted within the outer groove for storing clothing; and a heat pump device for drying the clothing within the drum using heated air, the heat pump device comprising: an air duct housing having an air inlet and an air outlet, the air inlet and the air outlet respectively communicating with the inner cavity of the drum; an evaporator, which is a microchannel evaporator, disposed within the air duct housing for dehumidifying the air drawn from the drum; and a condenser, which is a microchannel evaporator. A condenser, disposed within the airflow housing at a downstream position relative to the evaporator in the airflow direction, is used to heat air passing through the evaporator; and a fan is used to circulate air, thereby introducing air from the drum into the airflow housing via the air inlet, and introducing air that has passed through the evaporator and the condenser into the drum. An airflow guide member is provided within the airflow housing to divert air and guide it toward the windward side of the evaporator and / or the windward side of the condenser, at least a portion of the orthographic projection of the airflow guide member on the horizontal plane overlapping the orthographic projection of the evaporator and / or the condenser on the horizontal plane.

[0008] According to the first technical solution, a microchannel evaporator and a microchannel condenser are used. Compared with traditional heat exchangers, this effectively increases the airflow area while maintaining the same overall volume, which is beneficial for improving the drying efficiency of the drum-type garment processing device. Furthermore, by setting up air guide components, and ensuring that at least a portion of the orthographic projection of the air guide components on the horizontal plane overlaps with the orthographic projection of the evaporator and / or condenser on the horizontal plane, multiple air paths can be divided above or below the evaporator and / or condenser using the air guide components. These multiple air paths guide the drying air to different parts of the airflow area of ​​the evaporator and / or condenser, resulting in a uniform distribution of airflow directed to each part. Therefore, the airflow area of ​​the drying device can be effectively utilized to improve drying efficiency.

[0009] The second technical solution is based on the drum-type clothing processing device of the first technical solution, wherein the upper end of the evaporator and the upper end of the condenser are close to each other, and the lower ends of the evaporator and the lower ends of the condenser extend downwards at an angle. The evaporator and the condenser are arranged in an approximately inverted V shape, with the windward side of the evaporator located on the upper side and the windward side of the condenser located on the lower side.

[0010] According to the second technical solution, by arranging the evaporator and condenser in a roughly inverted V-shape, the irregularly shaped space within the drum-type garment processing device can be fully utilized, maximizing the airflow area of ​​the evaporator and condenser. Furthermore, the inclusion of air-guiding components further maximizes the utilization of the increased airflow area, thereby improving drying efficiency.

[0011] The third technical solution is based on the drum-type garment processing device of the second technical solution, wherein the air guiding component includes a first air guiding component, which diverts the air and guides the air toward the windward side of the evaporator.

[0012] According to the third technical solution, multiple air paths can be divided above the evaporator using the first air guide component. The drying air is guided to different parts of the evaporator's windward side using multiple air paths, so that the air volume guided to each part is evenly distributed. Thus, the windward area of ​​the evaporator can be effectively utilized to maximize the condensation efficiency.

[0013] The fourth technical solution is based on the drum-type garment processing device of the third technical solution, wherein the first air guide component includes at least one air guide rib disposed on the top wall of the air passage housing, and the air guide rib divides the air passage inside the air passage housing into at least two air passages in the horizontal direction.

[0014] According to the fourth technical solution, a first air guide component can be formed using a simple structure, and multiple air paths in the horizontal direction can be used to guide the drying air to different parts of the evaporator's windward side, so that the air volume guided to each part is evenly distributed.

[0015] The fifth technical solution is based on the drum-type garment processing device of the fourth technical solution, wherein, when viewed from above, the air guide ribs are in the shape of a straight line extending along the airflow direction.

[0016] According to the fifth technical solution, a first air guiding component can be formed using a simple structure, and the multiple divided air paths can extend in a straight line, which is beneficial to reducing air resistance.

[0017] The sixth technical solution is based on the drum-type garment processing device of the fourth technical solution. When viewed from above, the air guide ribs are in the shape of an arc that extends along the airflow direction while bending toward the upper end of the evaporator in a direction orthogonal to the airflow direction.

[0018] According to the sixth technical solution, it is beneficial to adjust the balance between the air volume guided on the upstream side of the evaporator facing the airflow direction and the air volume guided on the downstream side facing the airflow direction, so that the distribution of air volume guided to each part is more uniform.

[0019] The seventh technical solution is based on the drum-type garment processing device of the sixth technical solution, wherein there are multiple air guide ribs, and when viewed from above, the centers of the arc-shaped air guide ribs are staggered.

[0020] According to the seventh technical solution, it is more conducive to adjusting the air volume guided to different parts of the evaporator's windward side, so that the distribution of air volume guided to each part is more uniform.

[0021] The eighth technical solution is based on the drum-type garment processing device of the fourth technical solution, wherein the lower end of the air guide rib extends to the vicinity of the windward side of the evaporator.

[0022] According to the eighth technical solution, the air paths divided by the first air guide component can be reliably separated, which facilitates the adjustment of the air volume guided towards each air path.

[0023] The ninth technical solution is based on the drum-type clothing processing device of the eighth technical solution, wherein there are multiple air guide ribs extending from the upper end of the evaporator to the lower end, and the length of each air guide rib in the vertical direction increases sequentially.

[0024] According to the ninth technical solution, the air guide ribs can be designed to adapt to the tilt of the evaporator, and the air paths divided by the air guide ribs can be separated more reliably.

[0025] The tenth technical solution is based on the drum-type clothing processing device of the fourth technical solution, wherein there are multiple air guide ribs, and compared with the air guide ribs on the upper side of the evaporator, the air guide ribs on the lower side of the evaporator extend further upstream in the air flow direction.

[0026] According to the tenth technical solution, it is beneficial to guide the drying air to the upper air path of the evaporator among the multiple divided air paths, thereby facilitating the adjustment of the balance between the air volume guided towards each air path. This is because, in the first air path region, due to the flared shape of the air path shell and the left-right tilt of the evaporator, the drying air is more likely to flow towards the lower air path of the evaporator. By making the extension length of the air guide ribs on the upper side of the evaporator towards the upstream side shorter, it is beneficial to reduce the air resistance in the air path on the upper side of the evaporator, making it easier for the drying air to flow towards the upper air path of the evaporator.

[0027] The eleventh technical solution is, based on the drum-type garment processing device of the fourth technical solution, in at least two air paths divided by the air guide ribs, the width of the air path on the upper side of the evaporator is greater than the width of the air path on the lower side of the evaporator.

[0028] According to the eleventh technical solution, it is beneficial to guide the drying air to the upper air path of the evaporator among the multiple divided air paths, thereby facilitating the adjustment of the balance between the airflow guided to each air path. This is because, in the first air path region, due to the left and right tilt of the evaporator, the vertical length of the air path on the lower side of the evaporator is larger, resulting in a larger cross-sectional area. By making the width of the air path on the upper side of the evaporator greater than the width of the air path on the lower side of the evaporator, the cross-sectional area of ​​the air path on the upper side of the evaporator can be increased, making the air resistance of each air path more similar.

[0029] The twelfth technical solution is, based on the drum-type garment processing device of the third technical solution, the first air guide component includes an air guide plate disposed in the air passage housing, the air guide plate extends along the air flow direction, and divides the air passage in the air passage housing into two air passages in the vertical direction.

[0030] According to the twelfth technical solution, a first air guide component can be formed using a simple structure, and two air paths in the vertical direction can be used to guide the drying air to different parts of the evaporator's windward side, so that the air volume guided to each part is evenly distributed.

[0031] The thirteenth technical solution is, based on the drum-type garment processing device of any of the third to twelfth technical solutions, in the orthographic projection of the first air guide member and the evaporator on the horizontal plane, the length of the first air guide member in the airflow direction is the same as the length of the evaporator in the airflow direction; or, the width of the first air guide member in the direction orthogonal to the airflow direction is the same as the width of the evaporator in the direction orthogonal to the airflow direction.

[0032] According to the thirteenth technical solution, the various air paths divided by the first air guide component can be reliably separated, making it easy to adjust the air volume guided towards each air path.

[0033] The fourteenth technical solution is, based on the drum-type garment processing device of the second technical solution, the air guiding component includes a second air guiding component, which diverts the air and guides the air toward the windward side of the condenser.

[0034] According to the fourteenth technical solution, multiple air paths can be divided below the condenser using the second air guide component. The drying air can be guided to different parts of the condenser's windward side using multiple air paths, so that the air volume guided to each part is evenly distributed. Thus, the windward area of ​​the condenser can be effectively utilized to maximize the air heating efficiency.

[0035] The fifteenth technical solution is, based on the drum-type garment processing device of the fourteenth technical solution, the second air guide component includes an air guide plate disposed in the air passage housing, the air guide plate extends along the air flow direction, and divides the air passage in the air passage housing into two air passages in the vertical direction.

[0036] According to the fifteenth technical solution, a second air guide component can be formed using a simple structure, and two air paths in the vertical direction can be used to guide the drying air to different parts of the evaporator's windward side, making the air volume guided to each part evenly distributed. Furthermore, the installation of the second air guide component can avoid affecting the drainage of condensate formed on the evaporator surface.

[0037] The sixteenth technical solution is, based on the drum-type garment handling device of the fifteenth technical solution, that the downstream end of the air guide plate in the airflow direction extends to the vicinity of the windward side of the condenser.

[0038] According to the sixteenth technical solution, the air paths divided by the second air guide component can be reliably separated, making it easy to adjust the air volume guided towards each air path.

[0039] The seventeenth technical solution is, based on the drum-type garment handling device of the sixteenth technical solution, that the downstream end of the air guide plate in the airflow direction extends to near the center of the condenser's windward surface in the airflow direction.

[0040] According to the seventeenth technical solution, the second air guide component can be used to divide the air path for guiding drying air into half of the upstream side of the condenser in the direction of air flow and half of the downstream side of the condenser in the direction of air flow. This is beneficial for guiding the drying air to different parts of the condenser's windward surface, so that the air volume guided to each part is evenly distributed.

[0041] The eighteenth technical solution is, based on the drum-type garment processing device of the fifteenth technical solution, the air guide plate tilts downward from one end to the other end in the width direction orthogonal to the airflow direction.

[0042] According to the eighteenth technical solution, in the two air paths divided by the air guide plate, the vertical height of each air path can be changed from one end of the air guide plate to the other end. Thus, in each air path, the vertical height can be adjusted, which helps to make the air volume guided to each part of the windward side of the condenser more uniform.

[0043] The nineteenth technical solution is, based on the drum-type garment processing device of the fourteenth technical solution, the second air guide component includes at least one air guide rib disposed on the bottom wall of the air passage housing, the air guide rib extends along the air flow direction, and divides the air passage in the air passage housing into at least two air passages in the horizontal direction.

[0044] According to the nineteenth technical solution, a second air guide component can be formed using a simple structure, and multiple air paths in the horizontal direction can be used to guide the drying air to different parts of the condenser's windward side, so that the air volume guided to each part is evenly distributed.

[0045] The twentieth technical solution is, based on the drum-type garment processing device of any of the fourteenth to nineteenth technical solutions, in the orthogonal projection of the second air guide member and the condenser on the horizontal plane, the width of the second air guide member in the direction orthogonal to the air flow direction is the same as the width of the condenser in the direction orthogonal to the air flow direction; or, the length of the second air guide member in the air flow direction is the same as the length of the condenser in the air flow direction.

[0046] According to the twentieth technical solution, the various air paths divided by the second air guide component can be reliably separated, making it easy to adjust the air volume guided towards each air path.

[0047] The twenty-first technical solution is that, based on the drum-type clothing processing device of the second technical solution, the evaporator and the condenser are arranged along the rotation direction of the drum.

[0048] According to the twenty-first technical solution, by arranging the microchannel evaporator and microchannel condenser along the rotation direction of the drum, compared with the previous arrangement along the front and back direction, the air-facing area of ​​the microchannel evaporator and microchannel condenser can be designed to be larger, which is beneficial to improving drying efficiency.

[0049] The twenty-second technical solution is, based on the drum-type garment processing device of the twenty-first technical solution, the following are formed within the airflow housing: a first airflow region located upstream of the evaporator in the airflow direction; a second airflow region located below the evaporator and the condenser; and a third airflow region located downstream of the condenser in the airflow direction. The bottom wall of the airflow housing defining the second airflow region extends arcuately along the outer circumferential surface of the outer groove. A drain outlet is provided on the bottom wall of the airflow housing defining the second airflow region at a location below the condenser. The drain outlet is used to discharge condensate generated on the surface of the evaporator.

[0050] According to the twenty-second technical solution, the condensate flows along the curvature of the bottom wall to the drain outlet. Since the drain outlet is located above the drum, the condensate can flow directly to the drain pipe used to drain the washing water in the outer tank by gravity. The structure is simple and the cost is low. In addition, the flow direction of the condensate is consistent with the flow direction of the air passing through the evaporator, which is more conducive to the discharge of condensate.

[0051] The effects of the invention

[0052] According to the present invention, a drum-type garment processing device can be provided that can effectively utilize the windward area of ​​the drying device to improve drying efficiency. Attached Figure Description

Detailed Implementation

[0073] Next, specific embodiments of the present invention will be described with reference to the accompanying drawings.

[0074] (First Implementation)

[0075] The following is based on Figures 1 to 13 The first embodiment of the drum-type garment processing apparatus will be described.

[0076] As the drum-type garment handling device of this embodiment, a washer-dryer combo that combines washing and drying functions will be used as an example for description below. Those skilled in the art will understand that the drum-type garment handling device of this embodiment may also be a dryer that only has a drying function.

[0077] like Figures 1 to 2 As shown, the drum-type garment processing device 1 includes: a housing 10; an outer trough 20 supported within the housing 10; a drum 30 rotatably mounted within the outer trough 20 for storing garments; and a heat pump device 40 for drying the garments within the drum 30 using heated air. Additionally, for ease of explanation, as... Figure 1 The front-back, left-right, and up-down directions are defined as shown, and these directions will be used in subsequent attached figures.

[0078] like Figure 1As shown, the outer casing 10 forms a generally rectangular parallelepiped outline of the drum-type garment processing device 1, including a left wall panel 11, a right wall panel 12, a front wall panel (not shown), a rear wall panel 13, and a top wall panel (not shown) formed of sheet metal, resin, or other materials. To facilitate observation of the internal structure of the outer casing 10, [details omitted]. Figures 1 to 3 , Figure 9 The top and front wall panels are omitted from the diagram. Figure 13 The wall panels are omitted in the text.

[0079] like Figures 1 to 2 As shown, the outer groove 20 is a bottomed cylindrical shape with a clothing inlet 21 at one end. The outer groove 20 is installed inside the outer casing 10 with the clothing inlet 21 facing forward, and is elastically supported by a lower shock absorber 22 and an upper suspension spring 23, thereby preventing vibrations of the outer groove 20 from being transmitted to the outer casing 10. Additionally, although not shown, a door for opening and closing the clothing inlet 21 is installed on the front wall panel of the outer casing 10.

[0080] like Figure 2 As shown, the drum 30 is a bottomed cylindrical shape with one open end, used for storing clothes. The drum 30 is installed inside the outer tub 20 with its opening facing the clothes inlet 21 of the outer tub 20. Numerous fine holes can be formed on the outer peripheral wall and bottom wall of the drum 30, allowing washing water and heated air generated by the heat pump device 40 to flow between the outer tub 20 and the drum 30. Furthermore, the drum 30 is driven by a motor (not shown) and can rotate around a horizontally extending axis of rotation X. The direction of rotation of the drum 30 can be either... Figure 2 The rotation direction can be clockwise or counterclockwise, or it can switch between clockwise and counterclockwise directions continuously. In addition, the rotation axis X of the roller 30 can also be tilted upwards towards the clothing inlet 21.

[0081] like Figures 1 to 3 As shown, an integrally constructed heat pump device 40 is disposed in the upper space 14 located above the outer groove 20 within the outer casing 10. This heat pump device 40 is used to dry the clothes inside the drum 30 using heated air. Figure 2 As shown, the upper space 14 refers to the space sandwiched between the top wall plate and the upper arc-shaped outer peripheral surface of the outer groove 20 in the vertical direction. It includes not only the space above the highest part 20U of the outer groove 20, but also the spaces on the left and right sides of the highest part 20U and slightly below it (e.g.: Figure 2 (The space in which the suspension spring 23 is configured).

[0082] like Figure 4 , Figure 5 and Figure 7As shown, the heat pump device 40 includes: an air duct housing 50 having an air inlet 55 and an air outlet 56, the air inlet 55 and the air outlet 56 being connected to the inner cavity of the drum 30; an evaporator 60, which is a microchannel evaporator, disposed within the air duct housing 50 for dehumidifying the air drawn out from the drum 30; a condenser 70, which is a microchannel condenser, disposed within the air duct housing 50 at a position downstream of the evaporator 60 in the airflow direction, for heating the air passing through the evaporator 60; and a fan 80, disposed within the air duct housing 50 at a position upstream of the evaporator 60 in the airflow direction, for circulating air, thereby guiding the air in the drum 30 into the air duct housing 50 through the air inlet 55, and guiding the air that has passed through the evaporator 60 and the condenser 70 into the drum 30. In addition, the heat pump unit 40 also includes a compressor 90 for compressing the refrigerant flowing in the evaporator 60 and the condenser 70.

[0083] like Figures 5 to 7 As shown, the air duct housing 50 includes: an air inlet 51 that extends generally in a vertical direction and has an air inlet 55 at its lower end, as shown. Figure 13 As shown, the lower end of the air inlet 51 is connected to the outer groove 20 at the rear end of the outer peripheral surface of the outer groove 20, and communicates with the inner cavity of the roller 30 through a fine hole in the wall of the roller 30; the air outlet 52 extends generally vertically and has an air outlet 56 at its lower end, as shown in the figure. Figure 13 As shown, the lower end of the air outlet 52 is connected to the outer groove 20 at the front end of the outer peripheral surface of the outer groove 20 (i.e., the side of the clothing inlet 21), and communicates with the inner cavity of the roller 30 through the opening of the roller 30 corresponding to the clothing inlet 21; and the housing body 53 is connected between the air inlet 51 and the air outlet 52. In addition, a retractable corrugated tube 54 is also sandwiched between the air inlet 51 and the housing body 53 to prevent the vibration of the outer groove 20 from being transmitted to the housing body 53 through the air inlet 51. Although not shown, a retractable corrugated tube may also be sandwiched between the air outlet 52 and the housing body 53, for example. In addition, in this embodiment, by connecting the air outlet 52 to the front end of the outer peripheral surface of the outer groove 20, compared with the case where the air outlet 52 is connected to the rear end of the outer peripheral surface of the outer groove 20, the air heated by the heat pump device 40 can be directly supplied to the drum 30, and the air will not be dispersed due to the fine holes of the drum 30, so the clothes in the drum 30 can be dried more efficiently.

[0084] like Figures 5 to 7As shown, the housing body 53 has an upper housing 57 and a lower housing 58. The lower housing 58 is generally cup-shaped with an upward opening, and has a bottom wall portion 581 and a peripheral wall portion 582. An air inlet 51 is connected to the rear end of the bottom wall portion 581 via a bellows 54, and an air outlet 52 is connected to the front peripheral wall portion 582, with the air outlet 52 located approximately in front of the air inlet 51. The upper housing 57 is generally plate-shaped and is fixed to the upper end of the peripheral wall portion 582 of the lower housing 58 by screws or the like. An evaporator 60, a condenser 70, and a fan 80 are arranged within the internal space of the housing body 53, which is surrounded by the upper housing 57 and the lower housing 58. In addition, a compressor housing portion 583 is continuously provided forward on the front peripheral wall portion 582, and this compressor housing portion 583 is generally cylindrical with an upward opening. The compressor 90 is installed inside the compressor housing portion 583 and is located outside the internal space of the housing body 53. Thus, the evaporator 60, condenser 70, fan 80 and compressor 90 are arranged in an integral manner within the upper space 14 using the housing body 53.

[0085] like Figures 7 to 9 As shown, the evaporator 60 is a generally plate-shaped microchannel evaporator, with a pair of opposing plate surfaces forming the air-facing surface 61 and the air-discharging surface 62, respectively. The evaporator 60 cools the highly humid air flowing through it by absorbing heat from the refrigerant flowing inside, causing water vapor in the air to condense on the surface of the evaporator 60 as condensate, thus obtaining dry air. Figure 9 As shown, within the upper space 14, the evaporator 60 is arranged with its air-facing surface 61 on the upper side and its air-exhaust surface 62 on the lower side, both inclined relative to the horizontal line in the left-right direction. The height of the right end is higher than that of the left end; that is, the right end is the upper end 63, and the left end is the lower end 64. Furthermore, the evaporator 60 is located directly above the rotation axis X of the drum 30. Here, "the evaporator 60 is located directly above the rotation axis X of the drum 30" means that the orthographic projection of the evaporator 60 on the horizontal plane intersects with the orthographic projection of the rotation axis X of the drum 30 on the horizontal plane at more than one point.

[0086] like Figures 7 to 9 As shown, the condenser 70 is a generally plate-shaped microchannel condenser, with a pair of opposing plate surfaces forming the air-facing surface 71 and the air-discharging surface 72, respectively. The condenser 70 heats the dry air flowing through it by releasing heat from the refrigerant flowing inside, thereby obtaining high-temperature, dry air. Figure 9 As shown, within the upper space 14, the condenser 70 is arranged with the windward side 71 on the lower side and the air outlet side 72 on the upper side, and the windward side 71 and the air outlet side 72 are inclined relative to the horizontal line in the left and right directions. The height of the left end is higher than the height of the right end, that is, the left end becomes the upper end 73 and the right end becomes the lower end 74.

[0087] like Figure 9 As shown, within the upper space 14, the condenser 70 is located to the right of the evaporator 60. The evaporator 60 and condenser 70 are arranged in a left-right direction; in other words, they are arranged along the rotational direction of the drum 30 about its rotation axis X. Specifically, the upper ends 63 of the evaporator 60 and 70 are close to each other, and the lower end 64 of the evaporator 60 extends downwards at one side (left) in the rotational direction of the drum 30, while the lower end 74 of the condenser 70 extends downwards at the other side (right) in the rotational direction of the drum 30. Viewed along the rotational axis X (front-back direction) of the drum 30, the evaporator 60 and condenser 70 are arranged in a roughly inverted V-shape. Furthermore, the height of the lower end 64 of the evaporator 60 is higher than the height of the lower end 74 of the condenser 70. In addition, a roughly V-shaped partition 571 is provided on the surface of the upper housing 57 in a downward recessed manner. The partition 571 is located between the evaporator 60 and the condenser 70, and abuts against the upper end 63 of the evaporator 60 and the upper end 73 of the condenser 70, respectively.

[0088] The phrase "evaporator 60 and condenser 70 are arranged along the rotation direction of drum 30" means that, when viewed along the rotation axis X of drum 30, the position of evaporator 60 in the rotation direction of drum 30 is different from that of condenser 70. A typical example is that the orthographic projection of evaporator 60 onto a vertical plane orthogonal to the front-back direction and the orthographic projection of condenser 70 onto a vertical plane orthogonal to the front-back direction do not intersect. Additionally, besides... Figure 9 In addition to the configuration shown, it also includes configurations in which the evaporator 60 and the condenser 70, which are arranged parallel to the horizontal plane, are arranged sequentially in the left-right direction.

[0089] like Figure 7 , Figure 8 As shown, the fan 80 is disposed within the housing body 53 of the air duct housing 50, behind the condenser 70, and at the location where it connects to the air inlet 51 and the bellows 54. In other words, the condenser 70 and the fan 80 are arranged along the rotation axis X of the drum 30 (i.e., the front-to-back direction). Furthermore, in the airflow direction within the air duct housing 50, the fan 80 is located upstream of the evaporator 60.

[0090] Furthermore, the fan 80 is configured such that its rotating shaft extends vertically. By operating the fan, low-temperature, high-humidity air from the rear side of the drum 30 is drawn into the housing body 53 via the inlet 51 and the bellows 54. The low-temperature, high-humidity air drawn into the housing body 53 passes through the evaporator 60 from the upper windward side 61. Utilizing the heat absorption effect of the refrigerant in the evaporator 60, water vapor in the air condenses on the surface of the evaporator 60 and is released as condensate, thus obtaining low-temperature, dry air. The low-temperature, dry air exiting from the outlet side 62 of the evaporator 60 passes through the lower windward side 71. The condenser 70 uses the exothermic effect of the refrigerant inside the condenser 70 to heat the air, thereby obtaining high-temperature dry air. The high-temperature dry air coming out of the air outlet 72 of the condenser 70 enters the drum 30 from the front side through the air outlet 52. The high-temperature dry air comes into contact with the damp clothes inside the drum 30, evaporating the moisture contained in the clothes into water vapor and carrying it away, thus becoming low-temperature high-humidity air. The low-temperature high-humidity air is drawn back into the housing body 53 from the rear side of the drum 30 through the air inlet 51 and the bellows 54.

[0091] The airflow within the airflow housing 50 is divided into: a first airflow region S1, which is the region extending from the air inlet 55 of the air inlet 51 through the bellows 54 to the windward side 61 of the evaporator 60 within the housing body 53; in other words, the region located upstream of the evaporator 60 in the airflow direction; a second airflow region S2, which is the region within the housing body 53 located between the air outlet 62 of the evaporator 60 and the windward side 71 of the condenser 70; in other words, the region located below the evaporator 60 and the condenser 70; and a third airflow region S3, which is the region extending from the air outlet 72 of the condenser 70 to the air outlet 56 of the air outlet 52; in other words, the region located downstream of the condenser 70 in the airflow direction.

[0092] like Figure 8 As shown, the first airflow region S1 is formed to cause the air blown out of the fan 80 to turn and flow towards the windward side 61 of the evaporator 60 along the rotation axis X of the drum 30. When viewed from above, the first airflow region S1 is a funnel shape with a gradually increasing width, extending along the rotation axis X of the drum 30 after turning from the exhaust port 81 located on the side of the fan 80.

[0093] In addition, such as Figure 11As shown, the bottom wall 581 of the air passage housing 50 defining the first air passage region S1 is provided with a slope 585. The slope 585 slopes upward as it moves from rear to front; in other words, the slope 585 slopes upward as it approaches the evaporator 60. The angle α between the slope 585 and the horizontal plane is greater than 90° and less than 180°. More preferably, the angle α between the slope 585 and the horizontal plane is more than 120° and less than 150°. In addition, the slope 585 is formed parallel to the airflow passing through the slope 585 (including the case of "approximately parallel").

[0094] The slope 585 has a top end 5851 and a bottom end 5852. The bottom end 5852 is located at the portion after the bend in the first air passage area S1. The slope 585 extends along the direction of the rotation axis X of the roller 30 (i.e., the front-to-back direction). In other words, the slope 585 does not have a bend when viewed from above. However, it is not limited to this. Alternatively, the slope 585 may extend along the rotation axis X of the roller 30 after turning from the exhaust port 81 located on the side of the fan 80.

[0095] In addition, the bottom end 5852 of the slope 585 is curved in an arc and connected to other parts of the bottom wall portion 581 of the air passage housing 50 (i.e., the portion located on the upstream side of the slope 585).

[0096] The slope 585 does not extend to the windward side 61 of the evaporator 60 in the front-back direction. The top end 5851 of the slope 585 is curved in an arc and connects to other parts of the bottom wall portion 581 of the air passage housing 50 (i.e., the portion located downstream of the slope 585). However, this is not a limitation. Alternatively, the slope 585 may extend to the windward side 61 of the evaporator 60 in the front-back direction, and there may be no other parts of the bottom wall portion 581 between the top end 5851 of the slope 585 and the windward side 61 of the evaporator 60. Furthermore, both the bottom end 5852 and the top end 5851 of the slope 585 do not necessarily have to be curved in an arc; at least one of them may be curved and connect to other parts of the bottom wall portion 581 of the air passage housing 50.

[0097] Furthermore, the top end 5851 of the slope 585 is higher than the windward side 61 of the evaporator 60, but it is not limited to this. Alternatively, the top end 5851 of the slope 585 may be flush with the windward side 61 of the evaporator 60. In other words, the top end 5851 of the slope 585 is not lower than the windward side 61 of the evaporator 60. This reliably guides the air flowing within the air passage housing 50 toward the windward side 61 of the evaporator 60, preventing the flowing air from blowing toward the side of the evaporator 60.

[0098] In addition, such as Figure 12As shown, slope 585 slopes not only along the direction of rotation X of the drum 30 (i.e., the front-to-back direction), but also along the rotation direction of the drum 30 (i.e., the left-to-right direction). Specifically, as moving from right to left, the top tip 5851 of slope 585 slopes downward. In other words, in the rotation direction of the drum 30, as moving from the upper end 63 to the lower end 64 of the evaporator 60, the top tip 5851 of slope 585 slopes downward. Figure 10 and Figure 12 It can be seen that the slope of the top 5851 of the slope 585 in the left-right direction is approximately the same as the slope of the evaporator 60 in the left-right direction. Furthermore, although not shown, except for the top 5851, the slope 585 as a whole, or at least a portion including the top 5851, slopes downwards from right to left. Additionally, although not shown, other portions of the bottom wall 581 of the air passage housing 50 located between the top 5851 of the slope 585 and the windward side 61 of the evaporator 60 slope in the left-right direction with approximately the same slope as the top 5851 of the slope 585.

[0099] like Figure 10 As shown, the bottom wall portion 581 of the air passage housing 50 defining the second air passage area S2 extends in an arc shape along the outer peripheral surface of the outer tank 20. The bottom wall portion 581 of the air passage housing 50 defining the second air passage area S2 is provided with a drain outlet 584 at a position below the condenser 70. The drain outlet 584 is used to drain the condensate generated on the surface of the evaporator 60 and is connected to a drain pipe for draining the washing water in the outer tank 20 via a hose (not shown).

[0100] like Figure 7 , Figure 8 As shown, the compressor 90 is located within the upper space 14, positioned in front of the condenser 70 within the compressor housing 583, and near the right side of the outlet 52. In the direction of the rotation axis X of the drum 30, the compressor 90 is positioned closer to the clothing inlet 21 (front side) than the condenser 70, and the fan 80 is positioned opposite the condenser 70 (rear side) to the compressor 90. Alternatively, the compressor 90 may be positioned within the upper space 14 behind the evaporator 60.

[0101] By operating the compressor 90, the low-temperature, low-pressure gaseous refrigerant is compressed into a high-temperature, high-pressure gaseous refrigerant. Then, the refrigerant is sent into the condenser 70, where it releases heat and becomes a low-temperature, high-pressure refrigerant. Next, the refrigerant passes through the throttling device 91 and becomes a low-temperature, low-pressure gas-liquid two-phase refrigerant. Then, the refrigerant enters the evaporator 60, where it absorbs heat and becomes a low-temperature, low-pressure gaseous refrigerant. Finally, the refrigerant returns to the compressor 90 and is compressed again.

[0102] The drum-type garment handling device 1 of this embodiment operates as follows: Garments are placed into the drum 30 through the garment inlet 21 and washed like a conventional washing machine. When it is necessary to dry the washed garments, the fan 80 and compressor 90 operate simultaneously, using the evaporator 60 and condenser 70 to generate high-temperature dry air to dry the garments in the drum 30.

[0103] In the above embodiments, it is explained that... Figure 8 The fan 80 shown is positioned behind the condenser 70, but this is not a limitation. For example, the fan 80 can also be positioned in front of the condenser 70. In other words, the condenser 70 and the fan 80 can be arranged along the direction of the rotation axis X of the drum 30 (i.e., the front-to-back direction).

[0104] (Second Implementation)

[0105] The following is based on Figures 14 to 17 The second embodiment of the drum-type garment processing apparatus will be described.

[0106] The second embodiment differs from the first embodiment only in that the drum-type garment processing device of the second embodiment also includes an air guide member. Therefore, in the following description, this difference will be the main focus, and other structures will be described using the same method as the first embodiment, with simplified or omitted details.

[0107] like Figures 14 to 16 As shown, in the drum-type garment processing device 1 of this embodiment, an air guide member 59 is provided in the air passage housing 50 to split the air and guide the air to the windward surface 61 of the evaporator 60 and the windward surface 71 of the condenser 70, and at least a portion of the orthographic projection of the air guide member 59 on the horizontal plane overlaps with the orthographic projection of the evaporator 60 and the condenser 70 on the horizontal plane.

[0108] Specifically, the air guide component 59 includes a first air guide component 591 and a second air guide component 592. The first air guide component 591 is used to split the air and guide the air to the windward surface 61 of the evaporator 60, and the second air guide component 592 is used to split the air and guide the air to the windward surface 71 of the condenser 70.

[0109] First, let's explain the first air guide component 591.

[0110] like Figure 14 , Figure 15As shown, a first air guide member 591 is provided in the first air passage region S1, including at least one air guide rib 5910 (four air guide ribs 5910 in the illustrated structure) provided on the top wall portion 572 of the air passage housing 50. Each air guide rib 5910 extends downward from the inner surface of the top wall portion 572 toward the windward surface 61 of the evaporator 60, and is in the shape of a flat plate perpendicular to the left and right direction. By using these air guide ribs 5910, the air passage within the air passage housing 50 is divided into at least two air passages (five air passages in the illustrated structure) in the horizontal direction. Thus, the air blown by the fan 80 is guided through each air passage to different parts of the windward surface 61 of the evaporator 60. The air flows into the interior of the evaporator 60 from the windward surface 61 and flows out toward the second air passage region S2 from the air outlet surface 62.

[0111] like Figure 15 As shown, when viewed from above, the air guide ribs 5910 extend in a straight line along the direction of airflow. It should be noted that in the first airflow area S1 where the air guide ribs 5910 are installed, the "direction of airflow" is basically consistent with the front-to-back direction.

[0112] Combination Figure 15 and Figure 8 It can be seen that the entire orthographic projection of the first air guide component 591 on the horizontal plane overlaps with the orthographic projection of the evaporator 60 on the horizontal plane. In other words, the orthographic projection of the first air guide component 591 on the horizontal plane is located within the range of the orthographic projection of the evaporator 60 on the horizontal plane. However, it is not limited to this; it is sufficient that at least a portion of the orthographic projection of the first air guide component 591 on the horizontal plane overlaps with the orthographic projection of the evaporator 60 on the horizontal plane.

[0113] In addition, such as Figure 15 As shown, compared to the right-side guide rib 5910, the left-side guide rib 5910 extends further rearward. In other words, compared to the guide rib 5910 on the upper end 63 side of the evaporator 60, the guide rib 5910 on the lower end 64 side of the evaporator 60 extends further upstream in the airflow direction. Figure 15In the original design, from the rightmost first guide rib 5910 to the third guide rib 5910, the rear ends of each guide rib 5910 extend to a more rearward position, with the rear ends of the third and fourth guide ribs extending to approximately the same position. However, this is not a limitation; alternatively, from the rightmost first guide rib 5910 to the fourth guide rib 5910, the rear ends of each guide rib 5910 may extend to a more rearward position. Alternatively, the rear ends of the rightmost first and second guide ribs 5910 may extend to approximately the same position, and the rear ends of the third and fourth guide ribs may extend to approximately the same position, with the rear end of the third guide rib 5910 extending further rearward than the rear end of the first guide rib 5910.

[0114] In addition, combined Figure 15 and Figure 8 It can be seen that in the orthographic projection of the first air guide member 591 and the evaporator 60 onto the horizontal plane, the length of the first air guide member 591 in the airflow direction (i.e., the front-to-back direction) is the same as the length of the evaporator 60 in the airflow direction (i.e., the front-to-back direction). Specifically, when the first air guide member 591 includes multiple air guide ribs 5910, the length of the longest air guide rib 5910 in the airflow direction should be the same as the length of the evaporator 60 in the airflow direction. The statement "the length of the first air guide member 591 in the airflow direction is the same as the length of the evaporator 60 in the airflow direction" includes not only the case where their lengths are completely equal, but also the case where their lengths are approximately equal, for example, the ratio of their lengths being 0.9 to 1.1 can be included within this range.

[0115] In addition, such as Figure 14 As shown, the lower end 5911 of each air guide rib 5910 extends to the vicinity of the windward surface 61 of the evaporator 60. That is, considering manufacturing tolerances and assemblability, the lower end 5911 of each air guide rib 5910 extends as close as possible to the vicinity of the windward surface 61 of the evaporator 60. For example, the interval between the lower end 5911 of each air guide rib 5910 and the windward surface 61 of the evaporator 60 can be 0mm to 10mm.

[0116] Furthermore, to accommodate the structure in which the windward surface 61 of the evaporator 60 is inclined relative to the horizontal line in the left-right direction, the length of each air guide rib 5910 in the vertical direction increases sequentially from right to left (i.e. from the upper end 63 to the lower end 64 of the evaporator 60).

[0117] In addition, Figure 14 , Figure 15The diagram shows a structure in which multiple air paths divided by the air guide ribs 5910 have the same width in the left and right directions. However, it is also possible that in at least two air paths divided by the air guide ribs 5910, the width of the air path on the right side is greater than the width of the air path on the left side; in other words, the width of the air path on the side of the upper end 63 of the evaporator 60 is greater than the width of the air path on the side of the lower end 64 of the evaporator 60.

[0118] The above explains Figure 15 The air guide ribs 5910 shown are in a straight line extending along the direction of airflow, but are not limited to this. For example, they can also be as follows: Figure 17 As shown, when viewed from above, the air guide ribs 5910 extend along the airflow direction (i.e., the front-to-back direction) while curving to the right (i.e., the upper end 63 side of the evaporator 60) in a direction orthogonal to the airflow direction (i.e., the left-to-right direction). Furthermore, in the plurality of air guide ribs 5910, when viewed from above, the centers of each arc-shaped air guide rib 5910 are staggered. Other structures of such arc-shaped air guide ribs 5910 can appropriately employ the structures of the straight air guide ribs 5910 described above.

[0119] Next, the second air guide component 592 will be described.

[0120] like Figures 14 to 16 As shown, the second air guide member 592 is disposed in the second air passage region S2, including an air guide plate 5920 disposed within the air passage housing 50. The air guide plate 5920 extends along the airflow direction, dividing the air passage within the air passage housing 50 into two air passages in the vertical direction. It should be noted that in the second air passage region S2 where the air guide plate 5920 is disposed, the "airflow direction" is basically consistent with the horizontal direction.

[0121] like Figure 14 , Figure 16As shown, the air guide plate 5920 is generally flat and has two slots at its left end (i.e., the upstream side in the airflow direction). By engaging these two slots with ribs or the like that erected from the bottom wall portion 581 of the lower housing 58, the air guide plate 5920 is held in a vertical position between the windward surface 71 of the condenser 70 and the bottom wall portion 581 of the lower housing 58. Furthermore, the right end 5921 of the air guide plate 5920 (i.e., the downstream side in the airflow direction) is slightly curved upwards. Moreover, the right end 5921 of the air guide plate 5920 (i.e., the downstream side in the airflow direction) extends to the vicinity of the windward surface 71 of the condenser 70; more specifically, the downstream end 5921 of the air guide plate 5920 extends to the vicinity of the central portion of the windward surface 71 of the condenser 70 in the airflow direction. In other words, taking into account manufacturing errors and assemblability, the end 5921 of the air guide plate 5920 is extended as far as possible to the vicinity of the windward surface 71 of the condenser 70. For example, the distance between the end 5921 of the air guide plate 5920 and the windward surface 71 of the condenser 70 can be 0mm to 10mm. Thus, the air path in the second air path area is divided into upper and lower air paths by the air guide plate 5920, guiding the air that has passed through the evaporator 60 to different parts of the windward surface 71 of the condenser 70 via each air path. Specifically, the air is guided from the upper air path to the left side of the windward surface 71, and the air is guided from the lower air path to the right side of the windward surface 71. This air flows into the interior of the condenser 70 from the windward surface 71 and exits from the outlet surface 72 towards the third air path area S3.

[0122] Combination Figure 15 and Figure 8 It can be seen that the entire orthographic projection of the second air guide member 592 on the horizontal plane overlaps with the orthographic projection of the condenser 70 on the horizontal plane. In other words, the orthographic projection of the second air guide member 592 on the horizontal plane is located within the range of the orthographic projection of the condenser 70 on the horizontal plane. However, it is not limited to this; it is sufficient that at least a portion of the orthographic projection of the second air guide member 592 on the horizontal plane overlaps with the orthographic projection of the condenser 70 on the horizontal plane.

[0123] In addition, combined Figure 15 and Figure 8It can be seen that in the orthographic projection of the second air guide member 592 and the condenser 70 onto the horizontal plane, the width of the second air guide member 592 in the direction orthogonal to the airflow direction (i.e., the front-to-back direction) is the same as the width of the condenser 70 in the direction orthogonal to the airflow direction (i.e., the front-to-back direction). The statement "the width of the second air guide member 592 in the direction orthogonal to the airflow direction is the same as the width of the condenser 70 in the direction orthogonal to the airflow direction" includes not only the case where their lengths are completely equal, but also the case where their lengths are approximately equal, for example, the case where the ratio of their lengths is 0.9 to 1.1 can be included within its range.

[0124] like Figures 14 to 16 As shown, the air guide plate 5920 is inclined relative to the horizontal line in the left-right direction and horizontal relative to the horizontal line in the front-back direction. However, it is not limited to this; the air guide plate 5920 may also be inclined relative to the horizontal line in the front-back direction. In other words, the air guide plate 5920 may be inclined downward from one end to the other in the front-back direction (i.e., the width direction orthogonal to the airflow direction). For example, in Figure 15 In the structure shown, the air guide plate 5920 can be tilted downwards from the front end to the rear end. With this structure, in the upper air path of the two air paths divided by the air guide plate 5920, the vertical height of the air path can gradually increase from the front end to the rear end of the air guide plate 5920. This increases the airflow guided towards the left rear part of the windward side 71 of the condenser 70, making the airflow guided towards all parts of the windward side 71 of the condenser 70 more uniform.

[0125] In the above embodiments, it is described that the air guide member 59 has a structure that simultaneously guides air to the windward surface 61 of the evaporator 60 and a second air guide member 592 that guides air to the windward surface 71 of the condenser 70, but it is not limited to this. For example, the air guide member 59 may have a structure that only has one of the first air guide member 591 and the second air guide member 592.

[0126] Furthermore, while the above embodiments describe a structure where the first air guide member 591 is an air guide rib and the second air guide member 592 is an air guide plate, this is not a limitation. For example, the first air guide member 591 could be an air guide plate and the second air guide member 592 an air guide rib. In this case, the first air guide member 591 includes an air guide plate disposed within the airflow housing 50, extending along the airflow direction (i.e., the front-to-back direction) and dividing the airflow within the airflow housing 50 into two airflow paths in the vertical direction. In the orthographic projection of the first air guide member 591 and the evaporator 60 onto the horizontal plane, the width of the first air guide member 591 in the direction orthogonal to the airflow direction (i.e., the left-to-right direction) is the same as the width of the evaporator 60 in the direction orthogonal to the airflow direction (i.e., the left-to-right direction). Furthermore, the second air guide member 592 includes at least one air guide rib 5910 disposed on the bottom wall portion 581 of the air passage housing 50. The air guide rib 5910 extends along the airflow direction (i.e., the left-right direction) and divides the air passage within the air passage housing 50 into at least two air passages in the horizontal direction. In the orthographic projection of the second air guide member 592 and the condenser 70 onto the horizontal plane, the length of the second air guide member 592 in the airflow direction (i.e., the left-right direction) is the same as the length of the condenser 70 in the airflow direction (i.e., the left-right direction).
