Description

Technical Field

[0001] The utility model relates to a drum type clothes processing device. Background Art

[0002] At present, the demand for drum-type clothes processing devices with drying function is increasing. Such drum-type clothes processing devices include integrated washing and drying machines with both washing and drying functions, clothes dryers with only drying function, etc. In drum-type clothes processing devices, as a way to achieve the drying function, heat pump systems are being increasingly adopted due to their advantages of energy saving and gentleness on clothes.

[0003] For example, the filter device in the drum-type washing and drying machine disclosed in CN1536124A (Patent Document 1) is installed in the air blast passage in an inclined manner with the front end at the bottom and the rear end at the top, and can be pulled forward and downward relative to the air blast passage. However, Patent Document 1 does not conduct in-depth research on the installation structure of the filter device relative to the air blast passage. In the case where the installation structure is prone to loosening and falling off of the filter device due to repeated disassembly and assembly of the filter device, the filter device may fall from the drum-type washing and drying machine under the action of its own weight.

[0004] Therefore, for a drum type laundry processing apparatus having a drying device and a filter, it is an issue to develop a drum type laundry processing apparatus that can take into account both the stability of the filter after installation relative to the drying device and the ease of operation when removing the filter. Utility Model Content

[0005] Problems to be solved by utility models

[0006] The utility model is completed in view of the above-mentioned current situation, and its purpose is to provide a drum type clothes processing device which can take into account both the stability of the filter device after installation relative to the drying device and the convenience of operation when the filter device is taken out.

[0007] Solutions for solving problems

[0008] In order to achieve the above-mentioned object, the utility model provides a drum-type clothes processing device, which comprises: an outer shell; an outer drum, which is supported in the outer shell; an inner drum, which is rotatably installed in the outer drum and is used to store clothes; a drying device, which is located above the outer drum and uses heated air to dry the clothes in the inner drum; and a filtering device, which is arranged in an air path for air flow in the drying device during drying, and is used to filter foreign matter in the air flowing in the air path, and the filtering device can be close to the rotation axis of the inner drum at the front end and away from the rotation axis at the rear end. The inner cylinder is pulled out of the air passage in an inclined manner along the rotation axis of the inner cylinder, the filter device includes a locking device for locking the filter device relative to the drying device, the locking device includes at least one locking tongue that can be retracted along the width direction of the filter device and a movable component that makes the locking tongue retracted, and locking tongue holes are respectively provided at positions corresponding to the at least one locking tongue on the drying device housing of the drying device. When locking, the locking tongue is inserted into the corresponding locking tongue hole, and when unlocking, the locking tongue is withdrawn from the locking tongue hole by moving the movable component.

[0009] According to this structure, the filter device is locked relative to the drying device by inserting the locking tongue of the locking device into the locking tongue hole provided in the drying device housing. Since the matching structure between the locking tongue and the locking tongue hole is not easily damaged due to repeated locking and unlocking, the stability of the filter device after installation relative to the drying device can be ensured by a reliable locking structure. In a structure in which the filter device can be pulled out obliquely, by ensuring the stability of the filter device after installation, it is possible to reliably avoid the filter device from loosening, falling off, and then falling from the drum-type clothes processing device under the action of its own weight. In addition, when unlocking, the user only needs to move the movable member in the locking device to withdraw the locking tongue from the locking tongue hole, thereby facilitating the user to take out the filter device and clean and replace the components in the filter device. Therefore, it is possible to ensure that the operation convenience when taking out the filter device is high.

[0010] Preferably, a sliding track is provided on the inner wall of the locking device housing of the locking device, and the locking tongue moves along the sliding track.

[0011] According to this structure, the sliding track can make the movement of the lock tongue smoother and ensure that the lock tongue is in a specified track after withdrawing from the lock tongue hole, which is conducive to accurately inserting the lock tongue into the lock tongue hole when inserting the lock tongue into the lock tongue hole.

[0012] Preferably, two locking tongues and two movable components are provided in the locking device, and the two movable components are respectively connected integrally with the locking tongues.

[0013] According to this structure, since the two movable members are integrally connected to the respective locking tongues, there is no need to provide a conversion mechanism for converting the movement of the movable members into the movement of the locking tongues, which can simplify the structure and reduce the manufacturing cost of the entire machine.

[0014] Preferably, each of the movable members is provided with a pressing groove for a finger to be inserted and pressed along the width direction of the filter device.

[0015] According to this structure, when the locking device is to be unlocked, the user only needs to insert a finger into the pressing groove and press along the width direction of the filter device to drive the movable member to move, so that the lock tongue is withdrawn from the lock tongue hole. At this time, the user uses the finger inserted into the pressing groove, such as the thumb and index finger, to hold the locking device and take out the filter device. Therefore, it is convenient for the user to manually take out the filter device.

[0016] Preferably, a return spring for returning each of the movable members to the width direction is provided between the locking device housing and each of the movable members.

[0017] According to this structure, the movable member is always in a state where the lock tongue enters the lock tongue hole under the force of the return spring. When the user overcomes the force of the return spring and presses the pressing groove, the movable member moves so that the lock tongue withdraws from the lock tongue hole. When the user cancels the pressing of the pressing groove, the movable member returns to a state where the lock tongue enters the lock tongue hole under the force of the return spring. Thus, the locking and unlocking of the locking device can be reliably achieved using a simple structure.

[0018] Preferably, two locking tongues and one movable component are provided in the locking device, and the movable component is separately provided from each locking tongue.

[0019] According to this structure, each locking tongue can be driven to move by operating a movable member, so the operation of unlocking the locking device is relatively simple. In addition, when the movable member and each locking tongue arranged separately are damaged, they only need to be repaired or replaced respectively, so it is beneficial to reduce maintenance costs.

[0020] Preferably, the movable member and the locking tongues are linked in a wedge shape, and the movable member is pressed along the length direction of the filter device to drive the locking tongues to move along the width direction.

[0021] According to this structure, the movement of the movable member along the length direction of the filter device is converted into the movement of each locking tongue along the width direction of the filter device through the wedge-shaped linkage between the movable member and each locking tongue. Thus, the conversion of the movement of the movable member into the movement of the locking tongue can be reliably achieved using a simple structure.

[0022] Preferably, a return spring for returning the lock tongues in the width direction is provided between the locking device housing and each of the lock tongues, and a return spring for returning the movable member in the length direction is provided between the locking device housing and the movable member.

[0023] According to this structure, when the user overcomes the force of the return spring provided between the locking device housing and the movable member and presses the movable member, the movable member moves and applies force to each lock tongue so that each lock tongue overcomes the force of the return spring provided between the locking device housing and each lock tongue and moves, thereby causing the lock tongue to withdraw from the lock tongue hole. When the user cancels the pressing of the movable member, the movable member returns to its original position and no longer applies force to the lock tongue. At this time, the lock tongue returns to the state of entering the lock tongue hole under the action of the return spring. Thus, the locking and unlocking of the locking device can be reliably achieved using a simple structure.

[0024] Preferably, the drying device is provided with a rebounder, and the rebounder can eject the filter device from the air passage when the locking of the locking device is released.

[0025] According to this structure, when the locking device is unlocked, the filter device is ejected from the air duct by the rebounder, so the user can easily remove the ejected filter device without clamping the locking device. Therefore, the operation of removing the filter device is more convenient.

[0026] Preferably, two locking tongues and two movable components are provided in the locking device, and the two movable components correspond to the locking tongues respectively and are separately provided.

[0027] According to this structure, for the pairs of movable components and lock tongues that correspond to each other and are separately arranged, when one pair of movable components and lock tongues is damaged and the other pair of movable components and lock tongues is not damaged, while the locking function is maintained by using the undamaged pair of movable components and lock tongues, only the damaged movable components and / or lock tongues need to be repaired or replaced, thereby helping to reduce maintenance costs and ensuring that the locking device always has a locking function.

[0028] Preferably, for the movable component and the lock tongue corresponding to each other, the movable component can rotate in the positive direction around the rotation axis located on one end side of the movable component in the width direction, so that the other end of the movable component in the width direction contacts the lock tongue and drives the lock tongue to move along the width direction.

[0029] According to this structure, the movable member rotates to contact and drive the lock tongue, converting the rotation of the movable member into movement of the lock tongue along the width direction of the filter device. Therefore, the rotation of the movable member can be reliably converted into movement of the lock tongue with a simple structure.

[0030] Preferably, a return spring for returning the lock tongue in the width direction is provided between the locking device housing and each of the lock tongues, and a return spring for returning the movable member to reversely rotate and return the movable member around the rotation axis is provided between the locking device housing and each of the movable members.

[0031] According to this structure, when the user overcomes the force of the return spring provided between the locking device housing and the movable member and presses the movable member, the movable member rotates and applies force to the lock tongue so that the lock tongue overcomes the force of the return spring provided between the locking device housing and the lock tongue and moves, thereby causing the lock tongue to withdraw from the lock tongue hole. When the user cancels the pressing of the movable member, the movable member returns to its original position and no longer applies force to the lock tongue. At this time, the lock tongue returns to the state of entering the lock tongue hole under the action of the return spring. Thus, the locking and unlocking of the locking device can be reliably achieved using a simple structure.

[0032] Preferably, the outer shell includes a front panel assembly located on the front surface side of the drum-type clothing processing device, and the front panel assembly has an annular surface drawn from the front surface to the rear at the clothing inlet of the outer drum, and a filter device pull-out opening is provided on the annular surface. The filter device pull-out opening is located directly above the rotation axis of the inner drum, and the filter device can be loaded and unloaded relative to the filter device pull-out opening.

[0033] According to this structure, the annular surface formed by deep drawing of the front panel assembly can be effectively used to set the filter device pull-out opening, and the filter device can be easily inserted into the air path for air flow through the filter device pull-out opening set on the annular surface. In addition, since the filter device pull-out opening is located directly above the rotation axis of the inner cylinder, the appearance is good and it is convenient for the user to load and unload the filter device relative to the filter device pull-out opening.

DETAILED DESCRIPTION

[0069] Next, specific embodiments of the present application will be described with reference to the accompanying drawings.

[0070] As the drum type clothes processing device of the utility model, a washing and drying machine with both washing and drying functions is used as an example for description below. Those skilled in the art can understand that the drum type clothes processing device of the utility model can also be a clothes dryer with only drying function.

[0071] like Figure 1 to Figure 3 As shown, the drum type laundry processing device 1 comprises: a housing 10; an outer drum 20, which is supported in the housing 10; an inner drum 30, which is rotatably installed in the outer drum 20 and is used to store laundry; and a drying device 40, which uses heated air to dry the laundry in the drum type laundry processing device 1 (i.e., in the inner drum 30). In addition, for the convenience of explanation, as shown in FIG. Figure 1 The front-rear direction, the left-right direction, and the up-down direction are defined as shown, and these directions are used in the subsequent drawings.

[0072] like Figure 1 As shown, the outer shell 10 constitutes a roughly rectangular parallelepiped outline of the drum-type laundry processing device 1, including a left wall plate (not shown), a right wall plate 11, a front wall plate 12, a rear wall plate (not shown), and a top wall plate 16 formed of metal plates, resin plates, or other plates. In order to facilitate observation of the structure inside the outer shell 10, part or all of the wall plates constituting the outer shell 10 are appropriately omitted in the various drawings. The front wall plate 12 and other panel components located on the front surface side of the drum-type laundry processing device 1 constitute a front panel assembly 13. In other words, the outer shell 10 includes a front panel assembly 13 located on the front surface side of the drum-type laundry processing device 1, and the front panel of the drum-type laundry processing device 1 is constituted by the front panel assembly 13. At the upper side of the front panel assembly 13 (at Figure 1 There is a drawer opening for the detergent box (in the middle, on the upper left side).

[0073] like Figure 1 and Figure 3 As shown in FIG. 1 , the outer cylinder 20 is in the shape of a bottomed cylinder having a clothing inlet 21 at one end. The outer cylinder 20 is installed in the outer shell 10 with the clothing inlet 21 facing forward, and is elastically supported on the outer shell 10 by a damper 22 at the lower side and a suspension spring (not shown) at the upper side, thereby preventing the vibration of the outer cylinder 20 from being transmitted to the outer shell 10. In addition, as shown in FIG. Figure 1 As shown, a door assembly 15 for opening and closing the clothing input port 21 is installed on the front panel assembly 13. When the door assembly 15 is closed, a part of the front panel assembly 13 is covered by the door assembly 15.

[0074] like Figure 3As shown, the inner drum 30 is in the shape of a bottomed cylinder with one end open, and is used to store clothes. The inner drum 30 is installed in the outer drum 20 in a manner that the inner drum 30 is opened toward the clothing inlet 21 of the outer drum 20. Many fine holes can be formed in the wall portion of the outer circumference and the wall portion of the bottom side of the inner drum 30, so that the washing water and the heated air generated by the drying device 40 can flow between the outer drum 20 and the inner drum 30. In addition, the inner drum 30 is driven by a motor not shown in the figure, and can rotate around a rotation axis X extending in the horizontal direction. The rotation direction of the inner drum 30 can be either from Figure 3 The rotation axis X of the inner drum 30 may be tilted upward toward the clothing input port 21, or may be counterclockwise, or may be continuously switched between the clockwise and counterclockwise directions.

[0075] like Figure 5 As shown, an integrally constructed drying device 40 is arranged in the upper space portion 14 located above the outer drum 20 in the housing 10, and the drying device 40 uses heated air to dry the clothes in the inner drum 30. The upper space portion 14 refers to a space sandwiched by the top wall plate 16 and the arc-shaped outer peripheral surface on the upper side of the outer drum 20 in the up-down direction, and includes not only a space above the highest portion 20U of the outer drum 20, but also a space on both sides of the highest portion 20U and slightly below the highest portion 20U.

[0076] like Figure 4 , Figure 6 and Figure 8 As shown, the drying device 40 includes: an air path housing 50 (also referred to as a drying device housing 50), which has an air inlet 55 and an air outlet 56, the air inlet 55 is located on the front side or upper side of the outer drum 20, and the air outlet 56 is located on the rear side of the outer drum 30, and the air inlet 55 and the air outlet 56 are respectively connected to the inner cavity of the drum-type laundry processing device 1 (that is, the inner cavity of the inner drum 30); an evaporator 60, which is arranged in the air path housing 50, and dehumidifies the air derived from the inner drum 30 and flowing in the air path housing 50 ; a condenser 70, which is arranged in the air path housing 50 at a position downstream of the evaporator 60 in the air flow direction, and heats the air passing through the evaporator 60; and a fan 80, which is arranged in the air path housing 50 at a position downstream of the condenser 70 in the air flow direction, and is used to flow the air, so as to introduce the air in the inner cylinder 30 into the air path housing 50 through the air inlet 55, and introduce the air passing through the evaporator 60 and the condenser 70 into the inner cylinder 30 through the air outlet 56. In addition, the drying device 40 further includes a compressor 85, which is used to compress the refrigerant flowing in the evaporator 60 and the condenser 70.

[0077] like Figures 6 to 8As shown, the air duct housing 50 includes: an air inlet member 51, which extends substantially in the vertical direction and has an air inlet 55 at the lower end. Figure 3 As shown, the lower end of the air inlet member 51 is connected to the outer tube 20 by means of the outer tube fitting 24, and is connected to the inner cavity of the inner tube 30 through the fine holes on the wall of the inner tube 30; the air outlet member 52 has an air outlet 56 at its lower end, as shown in FIG. Figure 2 As shown, the lower end of the air outlet member 52 is connected to the outer tube 20 at the rear side wall (i.e., the bottom wall) of the outer tube 20, and is connected to the inner cavity of the inner tube 30 via an air supply port (not shown) provided on the bottom wall of the outer tube 20, and the air flowing out from the air outlet 56 flows into the outer tube 20 via the air supply port; and the shell body 53 is connected between the air inlet member 51 and the air outlet member 52. In addition, as shown Figure 6 As shown, the air inlet 51 includes a bellows portion 511 that can be expanded and contracted, thereby preventing the vibration of the outer cylinder 20 from being transmitted to the housing body 53 via the air inlet 51. Figure 2 As shown, the air outlet member 52 includes a first tube 521 having a retractable bellows portion 5211 connected to the shell body 53 and a second tube 522 connected to the first tube 521 , thereby preventing the vibration of the outer tube 20 from being transmitted to the shell body 53 via the air outlet member 52 .

[0078] like Figure 2 As shown, the first tube 521 and the second tube 522 are independent of each other, the first tube 521 is connected to the shell body 53, and one end of the second tube 522 is connected to the first tube 521. Fig.14 As shown, the rear side wall of the outer tube 20 is provided with an air supply port 201, and the other end of the second tube 522 is connected to the air supply port 201. That is, the second tube 522 connects the first tube 521 to the air supply port 201. Thus, the housing body 53 and the air supply port 201 are connected by the air outlet 52, and the air flowing out of the air outlet 56 of the air outlet 52 flows into the outer tube 20 through the air supply port 201. Fig.15 As shown, the second duct 522 extends in a substantially L-shaped shape when viewed from the side. In addition, as long as the first duct 521 and the air outlet 201 can be connected, the shape of the second duct 522 is not limited and can be appropriately changed.

[0079] like Figures 6 to 8As shown, the shell body 53 includes an upper shell 57 and a lower shell 58. The lower shell 58 is roughly cup-shaped and opens upward, and has a bottom wall 581 and a peripheral wall 582. The air inlet 51 is connected near the front end of the bottom wall 581, and the air outlet 52 is connected to the peripheral wall 582 on the rear side. The upper shell 57 is roughly plate-shaped and fixed to the upper end of the peripheral wall 582 of the lower shell 58 by screws or the like. The evaporator 60, the condenser 70, and the fan 80 are arranged in the internal space of the shell body 53 surrounded by the upper shell 57 and the lower shell 58. In addition, the compressor accommodating portion 583 is continuously provided forward on the peripheral wall 582 on the front side, and the compressor accommodating portion 583 is roughly cylindrical with a bottom and opens upward. The compressor 85 is arranged outside the internal space of the shell body 53 by being installed in the compressor accommodating portion 583. Thus, the evaporator 60 , the condenser 70 , the fan 80 , and the compressor 85 are arranged in the upper space portion 14 in an integral structure using the casing body 53 .

[0080] like Figure 5 , Figure 8 and Fig. 9 As shown, the evaporator 60 is a microchannel evaporator in a roughly plate-shaped manner, and a pair of plate surfaces facing each other are respectively the windward surface 61 and the windward surface 62, and air passes through the evaporator 60 from top to bottom. The evaporator 60 cools the high-humidity air flowing through the evaporator 60 outside by absorbing heat from the refrigerant flowing inside, so that the water vapor in the air condenses on the surface of the evaporator 60 and precipitates as condensed water, thereby obtaining dry air. Figure 5 As shown, in the upper space portion 14, the evaporator 60 is arranged in such a manner that the windward surface 61 is located at the upper side and the windward surface 62 is located at the lower side, the windward surface 61 and the windward surface 62 are inclined relative to the horizontal line in the left-right direction, and the height of the right end is higher than that of the left end, that is, the right end becomes the upper end 63, and the left end becomes the lower end 64. Thus, the humid air discharged from the inner cylinder 30 enters the evaporator 60 from the windward surface 61 on the upper side, and the water vapor in the air condenses on the surface of the evaporator 60 and precipitates as condensed water. The condensed water is separated from the surface of the evaporator 60 under the dual effects of its own gravity and the air flowing downward, which is conducive to the discharge of the condensed water. In addition, the evaporator 60 is located directly above the rotation axis X of the inner cylinder 30. Here, "the evaporator 60 is located directly above the rotation axis X of the inner cylinder 30" means that the orthographic projection of the evaporator 60 on the horizontal plane and the orthographic projection of the rotation axis X of the inner cylinder 30 on the horizontal plane have more than one intersection point.

[0081] like Figure 5 , Figure 8 and Fig. 9As shown, the condenser 70 is a microchannel condenser in a substantially plate shape, and a pair of plate surfaces facing each other are respectively a windward surface 71 and a wind outlet surface 72, and air passes through the condenser 70 from bottom to top. The condenser 70 heats the dry air flowing through the condenser 70 on the outside by releasing heat from the refrigerant flowing inside, thereby obtaining high-temperature and dry air. Figure 5 As shown, in the upper space portion 14, the condenser 70 is arranged in such a manner that the windward surface 71 is located at the lower side and the wind outlet surface 72 is located at the upper side, and the windward surface 71 and the wind outlet surface 72 are inclined relative to a horizontal line in the left and right directions, and the height of the left end is higher than that of the right end, that is, the left end becomes the upper end 73, and the right end becomes the lower end 74.

[0082] It should be noted that the evaporator 60 is not limited to the microchannel structure as long as it can dehumidify the air. For example, the evaporator 60 can also be a copper tube fin structure. The condenser 70 is not limited to the microchannel structure as long as it can heat the air. Compared with traditional heat exchangers, microchannel evaporators and microchannel condensers are smaller in size under the same heat exchange efficiency, which is conducive to the miniaturization of drum-type clothing processing devices. Therefore, in order to take into account both higher heat exchange efficiency and device miniaturization, it is preferred that at least one of the evaporator 60 and the condenser 70 is a microchannel structure, and in particular, the condenser 70 that heats the air is preferably a microchannel structure.

[0083] like Figure 5As shown, in the upper space portion 14, the condenser 70 is located on the right side of the evaporator 60, and the evaporator 60 and the condenser 70 are arranged along the left-right direction, in other words, the two are arranged along the rotation direction of the inner cylinder 30 around the rotation axis X. Specifically, the upper end 63 of the evaporator 60 and the upper end 73 of the condenser 70 are close to each other, and the lower end 64 of the evaporator 60 extends downwardly and obliquely toward one side (left side) in the rotation direction of the inner cylinder 30, and the lower end 74 of the condenser 70 extends downwardly and obliquely toward the other side (right side) in the rotation direction of the inner cylinder 30. When viewed along the direction of the rotation axis X of the inner cylinder 30 (front-back direction), the evaporator 60 and the condenser 70 are arranged in an inverted V shape. In addition, 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, so that the condenser 70 is extended downward longer and the condenser 70 is set larger. In addition, a V-shaped partition 571 is provided on the surface of the upper housing 57 in a manner recessed downward, and the partition 571 is provided between the evaporator 60 and the condenser 70, and is respectively in contact with the upper end 63 of the evaporator 60 and the upper end 73 of the condenser 70. By arranging the evaporator 60 and the condenser 70 along the rotation direction of the inner drum 30 and configuring them in a substantially inverted V shape, the space above the outer drum 20 can be fully utilized, and the heat exchange area of ​​the evaporator 60 and the condenser 70 can be increased as much as possible, so that the drying efficiency can be improved and the drying time can be shortened while ensuring the miniaturization of the drum-type laundry processing device in the height direction.

[0084] The above-mentioned “the evaporator 60 and the condenser 70 are arranged along the rotation direction of the inner cylinder 30” means that, when viewed along the direction of the rotation axis X of the inner cylinder 30, the position of the evaporator 60 in the rotation direction of the inner cylinder 30 is different from the position of the condenser 70 in the rotation direction of the inner cylinder 30. As a typical example, the orthographic projection of the evaporator 60 on the vertical plane orthogonal to the front-to-back direction and the orthographic projection of the condenser 70 on the vertical plane orthogonal to the front-to-back direction do not have an intersection.

[0085] like Figure 8As shown, the fan 80 is arranged behind the condenser 70 in the shell body 53 of the air path shell 50, and is arranged at the part of the shell body 53 connected to the air outlet member 52. That is to say, the condenser 70 and the fan 80 are arranged along the direction of the rotation axis X of the inner cylinder 30 (i.e., the front-to-back direction). In addition, in the flow direction of the air in the air path shell 50, the fan 80 is located on the downstream side of the condenser 70. Therefore, the evaporator 60, the condenser 70, and the fan 80 are arranged in sequence from the upstream side in the air flow direction. By arranging the filter device 90 on the upstream side of the evaporator 60 in the air flow direction, the structure of the filter device 90 described later being located on the upstream side of the evaporator 60, the condenser 70, and the fan 80 in the air flow direction can be realized, which is also conducive to realizing the structure of loading and unloading the filter device 90 described later relative to the filter device pull-out port H set on the front panel assembly 13.

[0086] In addition, if Figure 2 As shown, the fan 80 is located on the right side relative to the rotation axis X of the inner cylinder 30 in the left-right direction, and the air outlet 56 of the air outlet member 52 is located on the left side relative to the rotation axis X of the inner cylinder 30 in the left-right direction. Alternatively, the fan 80 is located on the left side relative to the rotation axis X of the inner cylinder 30 in the left-right direction, and the air outlet 56 of the air outlet member 52 is located on the right side relative to the rotation axis X of the inner cylinder 30 in the left-right direction. In other words, as long as the fan 80 and the air outlet 56 are located on opposite sides relative to the rotation axis X of the inner cylinder 30 in the left-right direction. Thus, it is possible to ensure that the air supply duct (i.e., the air outlet member 52) between the fan 80 and the air outlet 56 of the air path housing 50 has a larger setting space, avoid increasing the wind loss of the air outlet member 52 due to multiple bending of the air outlet member 52 in a small space, and help reduce the wind loss of the air outlet member 52, so that the flow of the wind blown out from the fan 80 can be smoother.

[0087] In addition, the fan 80 is arranged in a manner that the rotating shaft extends in a direction substantially perpendicular to the outer peripheral surface of the outer cylinder 20. By operating the fan 80, the low-temperature and high-humidity air in the inner cylinder 30 is sucked into the shell body 53 from the front side of the inner cylinder 30 through the air inlet 51; the low-temperature and high-humidity air sucked into the shell body 53 passes through the evaporator 60 from the upper windward surface 61, and the water vapor in the air condenses on the surface of the evaporator 60 and precipitates as condensed water by utilizing the heat absorption effect of the refrigerant in the evaporator 60, thereby obtaining low-temperature and dry air; the low-temperature and dry air coming out of the wind outlet surface 62 of the evaporator 60 passes through the lower windward surface 71, and the low-temperature and dry air is discharged from the outer cylinder 20. The air passes through the condenser 70 and is heated by utilizing the heat release of the refrigerant in the condenser 70, thereby obtaining high-temperature dry air; the high-temperature dry air coming out of the air outlet surface 72 of the condenser 70 enters the inner drum 30 from the rear side of the inner drum 30 through the air outlet piece 52; the high-temperature dry air contacts the wet clothes in the inner drum 30, evaporates the moisture contained in the clothes into water vapor and takes it away, thus becoming low-temperature and high-humidity air; the low-temperature and high-humidity air is again sucked into the shell body 53 from the front side of the inner drum 30 via the air inlet piece 51.

[0088] like Figure 5 , Figure 8 and Fig. 9 As shown, the air path in the air path shell 50 is divided into: a first air path area S1, which is an area from the air inlet 55 of the air inlet piece 51 to the windward surface 61 of the evaporator 60 in the shell body 53, in other words, an area located on the upstream side of the evaporator 60 in the air flow direction; a second air path area S2, which is an area between the air outlet surface 62 of the evaporator 60 and the windward surface 71 of the condenser 70 in the shell body 53, in other words, an area located on the lower side of the evaporator 60 and the condenser 70; and a third air path area S3, which is an area from the air outlet surface 72 of the condenser 70 to the air outlet 56 of the air outlet piece 52, in other words, an area located on the downstream side of the condenser 70 in the air flow direction.

[0089] like Figure 8 As shown, the first air passage area S1 is formed so that the air flowing in from the air inlet 55 flows from bottom to top under the negative pressure when the fan 80 is in operation, and then flows from right to left and thus flows from the front of the evaporator 60 toward the windward surface 61 of the evaporator 60.

[0090] like Fig. 9 As shown, the bottom wall portion 581 of the air path housing 50 defining the second air path region S2 extends in an arc shape along the outer peripheral surface of the outer cylinder 20, and a condensed water discharge port 584 is provided on the bottom wall portion 581 of the air path housing 50 defining the second air path region S2 (see Figure 8), specifically, a condensate outlet 584 is provided near the portion of the bottom wall 581 below the condenser 70, and the condensate outlet 584 is used to discharge the condensate generated by condensation on the surface of the evaporator 60, and is connected to a drainage structure for discharging the washing water in the outer cylinder 20 via a hose not shown in the figure. As a result, the condensate flows along the curvature of the bottom wall 581 to the condensate outlet 584. Since the condensate outlet 584 is located above the inner cylinder 30, the condensate can flow directly to the drain pipe for discharging the washing water in the outer cylinder 20 by gravity, and 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 60, which is more conducive to the discharge of the condensate.

[0091] like Figure 3 , Figure 5 and Figure 8 As shown, the compressor 85 is located in the upper space portion 14, and is arranged in the compressor accommodating portion 583 in front of the condenser 70, and is arranged near the upper side of the air intake member 51. As a result, the length of the connecting pipes between the compressor 85 and the evaporator 60 and the condenser 70 can be shortened. In addition, during the manufacturing process, after the outer cylinder 20 and the inner cylinder 30 are installed, the drying device 40 including the evaporator 60, the condenser 70, the fan 80 and the compressor 85 can be integrally installed in the upper space portion 14, which can greatly improve the assembly convenience compared with the case where the compressor 85 is located below the outer cylinder 20. In addition, in the direction of the rotation axis X of the inner cylinder 30, the compressor 85 is arranged at a position closer to the clothing inlet 21 side (front side) than the condenser 70, and the fan 80 is arranged on the opposite side (rear side) of the compressor 85 relative to the condenser 70.

[0092] like Figure 3 As shown, an external air inlet 585 is formed in the compressor housing 583. In addition, the compressor housing 583 is connected to the internal space of the shell body 53 (specifically, the third air path area S3) through a passage not shown in the figure. The external air introduced from the external air inlet 585 flows through the outer peripheral surface of the compressor 85, merges with the air flowing through the condenser 70 on the downstream side of the condenser 70 (i.e., in the third air path area S3) and flows toward the air outlet 56. The external air inlet 585 is located in the negative pressure area of ​​the air path shell 50 generated when the fan 80 is working. Preferably, the external air inlet 585 is arranged at the side (front side) of the compressor housing 583 opposite to the side (rear side) where the condenser 70 is located. The external air inlet 585 can be arranged at the side or bottom of the compressor housing 583. The opening shape of the external air inlet 585 may be circular or polygonal such as a quadrilateral. The ratio of the opening area of ​​the external air inlet 585 to the opening area of ​​the air inlet 55 is preferably 5% to 30%.

[0093] like Fig.10As shown, an on-off valve 586 controlled by a control unit may be connected to the external air inlet 585, and the external air inlet 585 may be opened and closed by the on-off valve 586. Fig.11 As shown, an air outlet 588 may also be provided on the outer drum 20, and the air outlet 588 is used to discharge the air in the outer drum 20 to the outside. The air outlet 588 is located in the upper half of the outer drum 20, and can be connected to the space in the detergent box of the drum-type laundry processing device 1 through a pipeline not shown in the figure, so as to discharge the air in the outer drum 20 to the outside. In addition, an on-off valve (not shown) controlled by the control unit to open and close the air outlet 588 may be connected to the air outlet 588, and the on-off valve is used to open and close the air outlet 588. Alternatively, a drain port (not shown) provided in the outer drum 20 for discharging the washing water in the outer drum 20 is also used as the air outlet 588. Since the drain port is connected to the outside of the drum-type laundry processing device 1 and no water is discharged from the drain port when the drying device 40 is working, the drain port can function as the air outlet 588 when the drying device 40 is working. At this time, the air outlet 588 can be opened and closed by an on-off valve provided in a drainage pipe for discharging the washing water in the outer drum 20 .

[0094] By operating the compressor 85, the low-temperature and low-pressure gaseous refrigerant is compressed to become a high-temperature and high-pressure gaseous refrigerant; then, the refrigerant is sent to the interior of the condenser 70, where it releases heat and becomes a low-temperature and high-pressure refrigerant; then, the refrigerant passes through the throttling device and becomes a low-temperature and low-pressure gas-liquid two-phase refrigerant; then, the refrigerant enters the evaporator 60, where it absorbs heat and becomes a low-temperature and low-pressure gaseous refrigerant; then, the refrigerant returns to the compressor 85 and is compressed again.

[0095] like Figure 3 and Figure 8 As shown, the drum-type laundry processing device 1 further includes a filter device 90 for filtering foreign matter such as lint in the air flowing in the air path of the drying device. The filter device 90 is arranged in the air path of the drying device 40 for air flow during drying, and is located on the upstream side of the evaporator 60, the condenser 70 and the fan 80 in the air flow direction. More specifically, the filter device 90 is located between the air inlet 55 and the evaporator 60 in the air flow direction. Thus, the air is filtered by the filter device 90 before passing through the evaporator 60, the condenser 70 and the fan 80, which can prevent foreign matter such as lint contained in the air from adhering to the evaporator 60, the condenser 70 and the fan 80, thereby reducing the drying efficiency. Therefore, it can help to improve the drying efficiency of the drum-type laundry processing device.

[0096] like Figure 1As shown, a filter device pull-out opening H is provided on the front panel assembly 13, and the filter device 90 can be loaded and unloaded relative to the filter device pull-out opening H. As a result, the filter device 90 can be loaded and unloaded from the space in front of the front panel assembly 13, and there is no need to reserve an operating space for loading and unloading the filter device 90 above the drum-type laundry processing device. Therefore, it can help save installation space. In addition, as Figure 3 As shown, the filter device 90 is installed and removed relative to the filter device pull-out opening H in a manner that the front end is close to the rotation axis X of the inner drum 30 and the rear end is away from the rotation axis X of the inner drum 30, that is, the filter device 90 can be pulled out from the air path in a manner that the front end is close to the rotation axis X of the inner drum 30 and the rear end is away from the rotation axis X of the inner drum 30. Therefore, compared with the structure in which the filter device 90 is installed and removed relative to the filter device pull-out opening H in a manner parallel to the rotation axis X of the inner drum 30, it is beneficial to increase the filtering area of ​​the filter device 90 and improve the filtering capacity of the filter device 90, and it is easier to set the filter device pull-out opening H on the annular surface 120 of the front panel assembly 13 described later. In addition, the filter device pull-out opening H is set at a portion on the front panel assembly 13 that is covered by the machine door assembly 15 when the machine door assembly 15 is closed. Therefore, when the machine door assembly 15 is closed when the drum-type laundry processing device is working, the user cannot see the filter device pull-out opening H and the filter device 90, which can improve the overall appearance of the drum-type laundry processing device.

[0097] The filter device 90 includes a locking device 92 for locking the filter device 90 relative to the drying device 40, so that when the filter device 90 is installed relative to the air passage of the drying device 40 (specifically, when the filter device 90 is installed relative to the filter device drawer opening H and is disposed in the air passage of the drying device 40), the locking device 92 is used to lock the filter device 90 to ensure the stability of the filter device 90 after installation. In addition, the unlocking operation of the locking device 92 is relatively simple, so the convenience of operation when taking out the filter device 90 can also be ensured. The specific structure of the locking device 92 is described in detail later.

[0098] In addition, Figure 3In the structure shown, the front panel assembly 13 has an annular surface 120 formed by drawing from the front surface to the rear at the clothing inlet 21, and the filter device pull-out opening H is set on the annular surface 120. When the door assembly 15 is closed, the annular surface 120 is covered by the door assembly 15. As a result, the annular surface 120 formed by drawing of the front panel assembly 13 can be effectively used to set the filter device pull-out opening H, and the filter device 90 can be easily inserted into the air path housing 50 for air flow through the filter device pull-out opening H set on the annular surface 120. Preferably, the filter device pull-out opening H is located directly above the rotation axis X of the inner drum 30. At this time, the air inlet 55 is offset to the right or left relative to the rotation axis X of the inner drum 30, and the filter device 90 is located between the air inlet 55 and the evaporator 60 in the air flow direction. Since the filter device pull-out opening H is located directly above the rotation axis X of the inner cylinder 30, the appearance is good and it is convenient for the user to load and unload the filter device 90 relative to the filter device pull-out opening H. On this basis, the air inlet 55 is offset to one side in the left-right direction relative to the rotation axis X of the inner cylinder 30, so that the space on the front side and the top of the outer cylinder 20 can be effectively utilized while ensuring miniaturization. In addition, since the filter device 90 is located between the air inlet 55 and the evaporator 60 in the air flow direction, the air from the air inlet 55 is filtered by the filter device 90 before flowing into the evaporator 60, which can prevent foreign matter such as lint contained in the air from being attached to other components except the filter device 90. Preferably, when the evaporator 60 is located directly above the rotation axis X of the inner cylinder 30, the filter device 90 is located directly in front of the evaporator 60, thereby, the filter device 90 can be set at a height position that is convenient for the user to load and unload, which is conducive to the loading and unloading operation of the filter device 90.

[0099] like Fig.12 and Fig.13As shown, a foreign matter receiving member 91 is provided at the rear side of the filter device 90, and the foreign matter receiving member 91 can receive foreign matter such as wire scraps dropped from the filter device 90 when the filter device 90 is pulled out. Thus, it is beneficial to collect and centrally clean foreign matter, and it can be prevented that foreign matter dropped from the filter device 90 when the filter device 90 is pulled out is scattered in the air duct housing 50 and attached to the evaporator 60, the condenser 70, the fan 80, etc. with the flow of air when the drying device 40 is working. Preferably, the foreign matter receiving member 91 is a filter element capable of filtering air, and is arranged substantially parallel to the filter device 90. The foreign matter receiving member 91 can be fixed in the air duct housing 50, or can be installed in the air duct housing 50 in a removable manner. Thus, the foreign matter receiving member 91 as a filter element can filter and collect foreign matter dropped from the filter device 90, and the foreign matter receiving member 91 allows air to flow through, thereby reducing the resistance caused to the air flow, and ensuring smooth air flow. In addition, since the foreign matter receiving member 91 is arranged substantially in parallel with the filter device 90, foreign matter can be collected more reliably, and the space required for setting up the foreign matter receiving member 91 can be saved, which is conducive to miniaturization.

[0100] like Figures 14 to 18 As shown, the drum type laundry processing device 1 further includes an auxiliary heating device A for heating the air flowing out from the housing body 53 of the air path housing 50. The auxiliary heating device A is located between the fan 80 and the air outlet 201 in the air flow direction. Specifically, the auxiliary heating device A is arranged in the second pipe 522 of the air outlet 52. The second pipe 522 has an air inlet 523 facing upward and an air outlet 524 (i.e., the air outlet 56) facing forward. The air inlet 523 is roughly circular and connected to the first pipe 521. The air outlet 524 is in a shape corresponding to the shape of the air outlet 201 provided on the rear side wall of the outer drum 20, and is connected to the air outlet 201. In addition, the shape of the air inlet 523 is not limited to a circle, and other shapes such as a polygon can also be used as needed. The auxiliary heating device A extends in a winding direction from the air inlet 523 to the air outlet 524 in the second pipe 522.

[0101] like Fig.14 As shown, a reinforcing rib 202 protruding rearward is provided on the outer surface of the rear side wall of the outer tube 20, and the reinforcing rib 202 is used to increase the strength of the rear side wall. A recess 203 is provided on the reinforcing rib 202 by removing a part of the reinforcing rib 202. A part of the second tube 522 is disposed in the recess 203.

[0102] like Figure 16 to Figure 18As shown, the longitudinal section of the auxiliary heating device A is substantially parallel to the central axis O of the air inlet 523 of the second tube 522, and the longitudinal section of the auxiliary heating device A is substantially perpendicular to the rotation axis X of the inner cylinder 30. Alternatively, the longitudinal section of the auxiliary heating device A is inclined at an angle of 90 to 180 degrees toward the axial outer side of the inner cylinder 30 relative to the rotation axis X of the inner cylinder 30. It should be noted that the longitudinal section of the auxiliary heating device A refers to a section obtained by cutting the auxiliary heating device A using a plane parallel to the front-to-back direction (i.e., a plane perpendicular to the left-to-right direction) including the central axis O of the air inlet 523.

[0103] The drum type clothes treatment device 1 of this embodiment works as follows. The clothes are put into the inner drum 30 through the clothes input port 21, and the clothes are washed like the conventional washing machine. When it is necessary to dry the washed clothes, the fan 80 and the compressor 85 are operated, and the air filtered by the filter device 90 is used to generate high-temperature dry air by the evaporator 60 and the condenser 70 to dry the clothes in the inner drum 30. In this process, the auxiliary heating device A is used to auxiliary heat the air at an appropriate stage (for example, at the beginning of the operation of the drying device 40), thereby shortening the time required for the air to reach a high temperature at the beginning of drying. In addition, after the compressor 85 has been working for a certain period of time and is in a high temperature state, the lower temperature external air is allowed to flow in from the external air inlet 585 to cool the compressor 85, and the air inside the device is discharged through the air outlet 588 to ensure that the air pressure inside the device is within a specified range.

[0104] Next, the specific structure of the locking device 92 included in the filter device 90 will be described in detail.

[0105] like Figure 19 to Figure 23 As shown, the locking device 92 having the first structure includes a locking device 92 along the width direction ( Fig.23 The two locking tongues 921 are arranged in the left-right direction of the paper in the figure and the movable member 922 for making the locking tongues 921 appear and disappear. The positions of the drying device housing 50 of the drying device 40 corresponding to the two locking tongues 921 are respectively provided with locking tongue holes 501. When locking, the locking tongues 921 are inserted into the corresponding locking tongue holes 501. When unlocking, the locking tongues 921 are withdrawn from the locking tongue holes 501 by moving the movable member 922.

[0106] A sliding track 923 is provided on the inner wall of the locking device housing 920 of the locking device 92, and the lock tongue 921 moves along the sliding track 923. Specifically, two movable members 922 are provided in the locking device 92, and the two movable members 922 are respectively formed integrally with each lock tongue 921. The movable member 922 is engaged with the sliding track 923 in a manner that it can move along the sliding track 923. By moving the movable member 922 along the sliding track 923, the lock tongue 921 is moved along the sliding track 923. The means for moving the movable member 922 is not limited, and preferably, a pressing groove 924 for inserting a finger and pressing along the width direction of the filter device 90 is provided in each of the two movable members 922. The user inserts, for example, a thumb and an index finger into the pressing groove 924 and presses along the width direction of the filter device 90, so that the movable member 922 moves along the sliding track 923 in the width direction of the filter device 90, thereby withdrawing the lock tongue 921 from the lock tongue hole 501. In addition, the movable member 922 does not necessarily have to be integrally formed with the lock tongue 921. The movable member 922 and the lock tongue 921 may be separately manufactured and then fixed together. In other words, the movable member 922 and the lock tongue 921 may be integrally connected.

[0107] Preferably, a return spring (not shown) is provided between the locking device housing 920 and each movable member 922 to return each movable member 922 along the width direction of the filter device 90. When the user cancels the pressing of the pressing groove 924, the movable member 922 returns to the state where the lock tongue 921 enters the lock tongue hole 501 under the action of the return spring.

[0108] like Fig.10 , Figure 24 to Figure 27 As shown, in the locking device 92 with the second structure, two locking tongues 921 and a movable member 922 are provided, and the movable member 922 is provided separately from each locking tongue 921. Specifically, the movable member 922 is provided with two active inclined portions 925, and each locking tongue 921 is provided with a driven inclined portion 926, and the two active inclined portions 925 are respectively in contact with each driven inclined portion 926. Fig. 27 When the movable member 922 is pressed in the vertical direction of the paper (in the vertical direction of the paper), the active inclined portion 925 of the movable member 922 moves and applies force to the driven inclined portion 926 of each locking tongue 921, that is, the movable member 922 and each locking tongue 921 are linked in a wedge shape, thereby driving each locking tongue 921 to move along the width direction of the filter device 90 ( Fig. 27 The locking tongue 921 moves in the left and right direction of the paper surface, thereby withdrawing from the locking tongue hole 501.

[0109] Preferably, a return spring (not shown) is provided between the locking device housing 920 and each locking tongue 921 to return the locking tongue 921 along the width direction of the filter device 90, and a return spring (not shown) is provided between the locking device housing 920 and the movable member 922 to return the movable member 922 along the length direction of the filter device 90. When the user cancels pressing the movable member 922, the movable member 922 returns to a state where no force is applied to the locking tongue 921 under the action of the return spring, and the locking tongue 921 returns to a state where it enters the locking tongue hole 501 under the action of the return spring.

[0110] Preferably, the drying device 40 is provided with a rebounder (not shown), which can pop out the filter device 90 from the air duct when the locking device 92 is released, specifically when the movable component 922 is pressed and the lock tongue 921 withdraws from the lock tongue hole 501.

[0111] like Figure 28 to Figure 30 As shown, in the locking device 92 having the third structure, two locking tongues 921 and two movable members 922 are provided. The two movable members 922 correspond to the locking tongues 921 and are separately provided. Specifically, in the width direction ( Fig.28 A rotation axis AX is provided on one end side (in the left-right direction of the paper in the figure) (the center of the rotation axis AX is referred to as the rotation axis), and a protrusion 9221 protruding toward the lock tongue 921 is provided on the other end of the movable member 922 opposite to the one end side where the rotation axis AX is located. Fig.28 When the movable member 922 is pressed (in the up and down directions on the paper), the end of the movable member 922 provided with the protrusion 9221 rotates around the rotation axis AX (i.e., the rotation axis) in the direction in which the protrusion 9221 approaches the lock tongue 921 (also referred to as positive rotation), so that the protrusion 9221 contacts the lock tongue 921 and applies force to the lock tongue 921, driving the lock tongue 921 to move along the width direction of the filter device 90, thereby the lock tongue 921 withdraws from the lock tongue hole 501.

[0112] exist Fig.30 The figure shows a case where a protrusion 9221 is provided at the other end of the movable member 922, but it is not limited to the structure with the protrusion 9221. The other end of the movable member 922 only needs to have a structure that contacts the locking tongue 921 and drives the locking tongue 921 to move along the width direction of the filter device 90 as the movable member 922 rotates in the forward direction.

[0113] Preferably, a return spring (not shown) is provided between the locking device housing 920 and each locking tongue 921 to return the locking tongue 921 along the width direction of the filter device 90, and a return spring (not shown) is provided between the locking device housing 920 and the movable member 922 to rotate the movable member 922 around the rotation axis AX (i.e., the rotation axis) in the direction in which the protrusion 9221 is away from the locking tongue 921 (also referred to as reverse rotation) and return. When the user cancels the pressing of the movable member 922, the movable member 922 is restored to a state where no force is applied to the locking tongue 921 under the action of the return spring, and the locking tongue 921 is restored to a state of entering the locking tongue hole 501 under the action of the return spring.

[0114] It should be noted that, in the above-mentioned locking device 92 having the first structure to the third structure, it is recorded that two locking tongues 921 are provided, but the number of locking tongues 921 is not limited to two, and the number of locking tongues 921 can be appropriately set according to actual conditions. In other words, there can be at least one locking tongue 921.
