Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and specifically relates to an air duct conversion device, and more particularly to a sleeve structure for mounting a baffle shaft of the air duct conversion device, and also to a clothing processing device equipped with the above-mentioned air duct conversion device. Background Art

[0002] Existing washer-dryers typically use a condenser-type drying system in drying mode. This involves a closed air duct. Dry air, heated by a condenser, is then fed into a drum containing clothes. The moist air, having been stripped of moisture from the clothes, is then returned to the evaporator for dehumidification. The dehumidified air is then heated again by the condenser and fed back into the drum, continuing the cycle. This cycle continuously removes moisture from the clothes until they are dry. After drying, a cooling process is required to lower the temperature inside the drum to a suitable level to prevent burns.

[0003] Existing washing-dryers typically use water cooling or compressor cooling in cooling mode, utilizing tap water or a compressor to lower the temperature inside the drum. However, tap water cooling suffers from low cooling efficiency, long cooling times, and wastes water resources. Compressor cooling, while highly efficient and time-efficient, is also very expensive.

[0004] In addition, the applicant previously designed a clothing processing device with two sets of clothing processing equipment, which can dry clothes separately; however, the drying equipment in the prior art can only dry clothes inside a single clothing processing device; therefore, when two sets of drying equipment are added to the clothing processing device, the size of the entire body structure increases and the number of equipment increases, resulting in increased product costs and increased space occupied.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a sleeve structure for mounting an air duct conversion device, so as to achieve the purpose of quickly installing the air duct baffle and the purpose of replacing the mounting sleeve. Another object of the present invention is to provide an air duct conversion device to achieve the purpose of correspondingly controlling the reversal of airflow in the air duct.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0008] A shaft sleeve structure for installing an air duct conversion device has a mounting groove on the side wall of the air duct, a bearing sleeve with a non-circular outer circumference is inserted and fixed in the mounting groove, and a mounting hole is provided on the bearing sleeve for inserting a baffle shaft of the air duct baffle.

[0009] Furthermore, the extension direction of the mounting groove is perpendicular to the side wall of the air duct, the hollow portion of the mounting groove is provided for the corresponding insertion and fixation of the bearing sleeve, and the axial direction of the mounting hole of the bearing sleeve is arranged perpendicular to the side wall of the air duct.

[0010] Furthermore, the inner wall cross-section of the installation groove is a square, and the outer peripheral cross-section of the bearing sleeve is a square that matches and fits the installation groove.

[0011] Furthermore, the outer cross section of the bearing sleeve is a square with chamfered corners, and the corners are in any shape of an arc or a straight line.

[0012] Furthermore, the outer peripheral cross-section of the bearing sleeve is a regular hexagon, the inner wall cross-section of the mounting groove is a square, and the distance between two opposite sides of the regular hexagon is equal to the side length of the square.

[0013] Furthermore, a first retaining rib and a second retaining rib arranged to intersect and form a certain angle are provided on the side wall of the air duct, and the mounting groove is provided at the intersection of the first retaining rib and the second retaining rib.

[0014] Furthermore, the axis of the bearing sleeve installed in the installation groove coincides with the intersection of the extension directions of the first retaining rib and the second retaining rib.

[0015] Furthermore, the first baffle rib and the second baffle rib protrude and extend from the side wall of the duct toward the interior of the duct, and the first baffle rib extends along the first position of the duct baffle of the duct conversion device, and the second baffle rib extends along the second position of the duct baffle of the duct conversion device, so that the duct baffle rotates around the baffle axis between the first baffle rib and the second baffle rib.

[0016] Furthermore, the cross section of the mounting hole provided on the bearing sleeve is a circular hole corresponding to and plugged into the baffle shaft, and the diameter of the circular hole is set to be the same as the diameter of the baffle shaft.

[0017] Another object of the present invention is to provide an air duct conversion device, which includes an air duct baffle mounted on the air duct and can rotate relatively; characterized in that the baffle shaft of the air duct baffle is installed in the air duct via a sleeve structure as described in any one of claims 1 to 9 above; the motor output shaft is connected to the air duct baffle via a connecting rod mechanism, so that during the rotation of the motor output shaft, the air duct baffle is driven by the connecting rod mechanism to rotate around the axis, so that the air duct baffle is switched between a first position and a second position.

[0018] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0019] By arranging a detachable bearing sleeve on the side wall of the air duct, the bearing of the air duct reversing device can be detached and replaced, thereby achieving the purpose of detachable installation and rapid assembly and replacement of the bearing sleeve of the baffle shaft.

[0020] By setting the bearing sleeve to have a regular hexagonal cross-section, the bearing sleeve cannot rotate relative to the mounting slot after being installed in the mounting slot, thereby achieving the purpose of supporting and positioning the baffle shaft inserted in the bearing sleeve and allowing it to rotate around the axis relative to the air duct.

[0049] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0051] like Figures 1 to 3 As shown, an embodiment of the present invention introduces a duct conversion device 200, which includes a duct baffle 4 installed on the duct 100 and can rotate relatively; the output shaft of the motor 1 is connected to the duct baffle 4 through a connecting rod mechanism, so that during the rotation of the output shaft of the motor 1, the duct baffle 4 is driven to rotate around the axis through the connecting rod mechanism, so that the duct baffle 4 switches and moves between the first position and the second position.

[0052] Through the above arrangement, the duct baffle in the duct can swing and rotate accordingly with the rotation of the motor output shaft under the transmission of the connecting rod structure, thereby realizing the corresponding opening and closing control of different openings in the duct, so as to achieve the purpose of controlling the direction of the airflow in the duct.

[0053] In an embodiment of the present invention, the connecting rod mechanism includes an adapter 3 and a connecting beam 2 that are relatively rotatable. The connecting beam 2 is plug-in connected to the output shaft of the motor 1 and can rotate relative to the output shaft of the motor 1 around the output shaft of the motor 1. The adapter 3 is plug-in connected to the baffle shaft 411 of the air duct baffle 4 in a non-rotatable manner.

[0054] like Figure 1 As shown, when the air duct baffle 4 is in the first position, the output shaft of the motor 1 is away from the air duct 100, the connecting beam 2 is driven away from the air duct 100, and the adapter 3 moves to the uppermost end, thereby causing the air duct baffle 4 to rotate upward around the axis to the first position to close the upper end opening of the air duct 100 and connect the air duct 100 with the lower end opening.

[0055] like Figure 2 As shown, when the air duct baffle 4 is in the second position, the output shaft of the motor 1 is close to the air duct 100, the connecting beam 2 is driven to the position close to the air duct 100, and the adapter 3 moves to the lower end, thereby causing the air duct baffle 4 to rotate downward around the axis to be in the second position to close the lower end opening of the air duct 100 and connect the air duct 100 with the upper end opening.

[0056] In an embodiment of the present invention, one end of the air duct baffle 4 is provided with a baffle shaft 411 extending horizontally to both sides. The baffle shaft 411 is plugged and fixed corresponding to the two side walls of the air duct 100, so that the air duct baffle 4 can be installed in the air duct 100 in a relatively rotatable manner; one end of the baffle shaft 411 passes through the air duct 100 and is fixedly connected to the adapter 3.

[0057] In an embodiment of the present invention, a first joint 21 and a second joint 22 are fixedly installed at both ends of the connecting beam 2, respectively. The first joint 21 and the adapter shaft 31 of the adapter 3 can be plugged and fixed so as to rotate relative to each other around the axis, and the second joint 22 and the eccentric shaft segment 111 of the motor 1 can be plugged and fixed so as to rotate relative to each other around the axis.

[0058] In this embodiment of the present invention, the motor output shaft is an eccentric shaft structure, comprising an eccentric shaft segment 111 that rotates about the center of the motor. The eccentric shaft segment 111 is plugged and fixed to the second joint 22 of the connecting crossbeam 2 so as to be rotatable relative to each other. Rotation of the eccentric shaft segment 111 drives the connecting crossbeam 3 to move, thereby driving the air duct baffle 4 to rotate about the baffle axis 411 via the adapter 3. This allows the eccentric shaft segment of the motor output shaft to swing and rotate between its uppermost and lowermost positions, correspondingly controlling the air duct baffle to switch between its first and second positions.

[0059] Example 1

[0060] like Figures 1 to 6As shown, this embodiment introduces a shaft sleeve structure for mounting the baffle shaft of an air duct conversion device. A baffle shaft 411 extending horizontally to both sides is provided at one end of the air duct baffle 4. The baffle shaft 411 is plugged and fixed to the corresponding side walls of the air duct 100, allowing the baffle 411 to be relatively rotatably installed within the air duct 100. One end of the baffle shaft 411 passes through the air duct 100 and is fixedly connected to the adapter 3. A mounting groove 203 is provided on the air duct side wall 101. A bearing sleeve 204 with a non-circular outer circumference is inserted and fixed into the mounting groove 203. The bearing sleeve 204 is provided with a mounting hole 205 for corresponding insertion of the baffle shaft 411 of the air duct baffle 4.

[0061] By arranging a detachable bearing sleeve on the side wall of the air duct, the bearing of the air duct reversing device can be detached and replaced, thereby achieving the purpose of detachable installation and rapid assembly and replacement of the bearing sleeve of the baffle shaft.

[0062] In this embodiment, the extension direction of the installation groove 203 is perpendicular to the air duct side wall 101, the hollow portion of the installation groove 203 is provided for the corresponding insertion and fixation of the bearing sleeve 204, and the axial direction of the installation hole 205 of the bearing sleeve 204 is set perpendicular to the air duct side wall 101.

[0063] In this embodiment, the inner wall of the mounting groove 203 has a square cross-section, and the outer peripheral cross-section of the bearing sleeve 204 has a square cross-section that matches the mounting groove 203. By arranging the bearing sleeve in a direction that matches the mounting groove, the bearing sleeve is non-rotatable when inserted into the mounting groove, thereby ensuring the reliable fixation of the bearing sleeve.

[0064] In this embodiment, the outer cross-section of the bearing sleeve 204 is a square with chamfered corners. The corners can be either arc-shaped or straight-line-shaped. By providing the corners on the outer periphery of the bearing sleeve, gaps are formed between the corners and the mounting grooves, making it easier for users to remove and install the bearing sleeve.

[0065] like Figure 6 As shown, in this embodiment, the outer cross-section of the bearing sleeve 204 is a regular hexagon, and the inner cross-section of the mounting slot 203 is a square. The distance between two opposite sides of the regular hexagon is equal to the side length of the square. By configuring the bearing sleeve with a regular hexagonal outer cross-section, the bearing sleeve cannot rotate relative to the mounting slot after being installed in the mounting slot. This achieves the purpose of supporting and positioning the baffle shaft inserted into the bearing sleeve and allowing it to rotate about its axis relative to the air duct.

[0066] In this embodiment, a first retaining rib 201 and a second retaining rib 202 are provided on the air duct side wall 101 , and the first retaining rib 201 and the second retaining rib 202 are provided at a certain angle to each other. The mounting groove 203 is provided at the intersection of the first retaining rib 201 and the second retaining rib 202 .

[0067] like Figure 4 and Figure 5 As shown, in this embodiment, the axis of the bearing sleeve 204 installed in the installation groove 203 coincides with the intersection of the extension directions of the first and second retaining ribs 201 and 202. By providing the inwardly protruding first and second retaining ribs in the air duct, the position of the air duct baffle is restricted, thereby preventing the air duct baffle from deviating from the restricted position and sliding into other positions in the air duct, thereby ensuring the smooth switching operation of the air duct switching device.

[0068] In this embodiment, the first baffle 201 and the second baffle 202 protrude and extend from the duct side wall 101 toward the interior of the duct 100, and the first baffle 201 extends along the first position of the duct baffle 4 of the duct conversion device 200, and the second baffle 202 extends along the second position of the duct baffle 4 of the duct conversion device 200, so that the duct baffle 4 rotates around the baffle axis 41 between the first baffle 201 and the second baffle 202.

[0069] In this embodiment, the cross section of the mounting hole 205 provided on the bearing sleeve 204 is a circular hole corresponding to and plugged into the baffle shaft 411 , and the diameter of the circular hole is set to be the same as the diameter of the baffle shaft 411 .

[0070] Example 2

[0071] like Figures 1 to 3 ,like Figures 7 to 11 As shown, this embodiment introduces an adapter 3 for an air duct conversion device. An adapter shaft 31 and an adapter sleeve 32 are respectively provided at both ends of the adapter 3. The adapter shaft 31 is connected to the connecting beam 2 of the air duct conversion device 200 so as to be rotatable around the axis, and the adapter sleeve 32 is fixedly connected to the air duct baffle 4 of the air duct conversion device 200 so as to be non-rotatable relative to each other.

[0072] By arranging the above-mentioned adapter on the air duct conversion device, two different plug-in structures can be integrated on the adapter, thereby ensuring that the two ends of the adapter are rotatably connected and non-relatively rotatably connected corresponding to different components, thereby achieving the purpose of transmitting the air duct baffle of the air duct conversion device.

[0073] like Figure 8 As Figure 10 As shown, in this embodiment, the axes of the adapter sleeve 32 and the adapter shaft 31 are parallel and are both arranged on the same side of the adapter 3. In this embodiment, the axes of the adapter shaft 31 and the adapter sleeve 32 are parallel and are both arranged perpendicular to the extension direction of the adapter 3.

[0074] In this embodiment, the adapter sleeve 32 is a sleeve structure protruding and extending from the adapter to one side. One end of the sleeve structure is open for the baffle shaft 411 of the air duct conversion device 100 to be inserted into, and the other end is provided with a socket 36 for the baffle shaft to pass through.

[0075] like Figures 9 to 11 As shown, in this embodiment, the adapter 3 is provided with a countersunk groove 35 for mounting a locking nut 33. The countersunk groove 35 is coaxially arranged with the adapter sleeve 32 and is located on opposite sides of the adapter 3. The countersunk groove 35 communicates with the adapter sleeve 32 via a socket 36. The countersunk groove 35, socket 36, and adapter sleeve 32 are all coaxially arranged. Preferably, the opening of the countersunk groove 35 is provided with a circle of ribs protruding outwardly beyond the corresponding side of the adapter to facilitate tightening the locking nut within the countersunk groove. By providing a countersunk groove on the adapter shaft, the locking nut is embedded in the countersunk groove, ensuring that the outer end surface of the locking nut does not protrude from the adapter, thereby improving the overall compactness of the air duct conversion device.

[0076] like Figures 8 to 10 As shown, in this embodiment, the outer periphery of the adapter sleeve 32 is provided with a plurality of spaced-apart reinforcing ribs 34 extending in a direction parallel to the axis of the sleeve structure. The lower end of the reinforcing rib 34 extends to the adapter 3 and the upper end extends to the end of the sleeve structure.

[0077] like Figure 8 As shown, in this embodiment, the inner cross-section of the adapter sleeve 32 of the sleeve structure is non-circular, so that the baffle shaft 411 is plugged in and fixed in a non-rotatable manner; preferably, the inner cross-section of the adapter sleeve 32 of the sleeve structure is a partial circle intercepted by two parallel line segments, that is, the inner cross-section of the adapter sleeve 32 is an irregular shape surrounded by two parallel line segments on two opposite sides and symmetrical arc segments on the other two opposite sides.

[0078] In this embodiment, the adapter shaft 31 is a columnar structure protruding and extending from the adapter to one side. The axis of the columnar structure adapter shaft 31 is perpendicular to the extension direction of the adapter 3. The height of the columnar structure adapter shaft 31 is set to be level with the adapter sleeve 32, and the cross-section of the columnar structure adapter shaft 31 is circular.

[0079] In this embodiment, the middle part of the columnar structure adapter shaft 31 is provided with a circle of grooves 37 extending along the outer wall of the adapter to accommodate the corresponding protrusions on the adapter beam 2 joint; the extension surface of the groove 37 is perpendicular to the axis of the adapter shaft 31. By providing the groove on the adapter shaft, the adapter shaft is fixed in place by the groove after being connected to the corresponding joint, thereby preventing the adapter shaft from moving axially and separating from the joint, thereby achieving the purpose of fixing the adapter shaft in the axial direction.

[0080] By adding an adapter to the duct conversion device, the connecting beam only needs to swing a smaller range of angles to drive the adapter to produce a larger range of rotation angles, thereby ensuring the rotation range of the duct baffle and achieving the purpose of reducing the moving path of the duct conversion device.

[0081] Example 3

[0082] like Figure 3 、 Figure 7 and Figures 12 to 14 As shown, this embodiment introduces an air duct baffle 4 of an air duct conversion device 200, comprising a baffle body 41 and a frame 42. A baffle shaft 411 extending horizontally in both directions is provided on one side of the baffle body 41, and the frame encloses three sides of the baffle body except for the baffle shaft 411. The baffle body 41 and the baffle shaft 411 are integrally arranged and rotate together when driven by the motor 1 to open and close the air duct 100.

[0083] In this embodiment, the air duct conversion device 200 is fixed to the shell by a fixing device, and the air duct baffle 4 switches and moves between the first position and the second position to realize the opening and closing of the air duct 100. Under the interaction of the air duct side wall and the air duct baffle 4, the gas can only flow along the prescribed route, thereby avoiding gas leakage.

[0084] In this embodiment, the baffle shaft 411 of the duct baffle 4 is respectively connected to the fixing device, the adapter 3 of the duct conversion device 200 and the duct side wall to install and fix the duct baffle 4. In addition, under the drive of the duct conversion device 200, the adapter 3 drives the baffle shaft 411 to rotate, and then drives the entire duct baffle 4 to rotate.

[0085] like Figure 11 and Figure 13 As shown, in this embodiment, the end of the baffle shaft 411 passing through the air duct baffle 4 is stepped, and a first shaft segment 4111 and a second shaft segment 4112 are provided from the outside to the inside. The diameter of the second shaft segment 4112 is larger than the diameter of the first shaft segment 4111. The top end of the first shaft segment 4111 is connected to the side wall of the air duct, and the second shaft segment 4112 is connected to the other end of the first shaft segment 4111 and extends along the axial direction of the first shaft segment 4111. The cross-section of the second shaft segment 4112 is non-circular, and the outer wall of the second shaft segment 4112 is fitted and plugged into the inner circumferential surface of the adapter sleeve 32 of the adapter 3, so that the second shaft segment 4112 and the adapter 3 are fixed in a non-rotatable manner relative to each other; the first shaft segment 4111 passes through the inner hole 36 of the adapter sleeve 32, and the outer periphery of the first shaft segment 4111 is provided with a thread, so that the first shaft segment 4111 is threadedly engaged and fixed with the locking nut 33, and the outer circumference of the second shaft segment 4112 is larger than the diameter of the hole 36.

[0086] In this embodiment, a plurality of inwardly recessed side grooves 4113 are provided in the middle of the baffle shaft 411 of the air duct baffle 4. The side grooves 4113 are evenly distributed axially on the side of the baffle shaft 411 away from the baffle body 41. The side grooves 4113 cooperate with the fixing device to fix the air duct baffle 4 to the fixing device.

[0087] In this embodiment, the shape and size of the baffle body 41 of the duct baffle 4 are aligned with the shape and size of the duct inlet and outlet, allowing the duct baffle 4 to completely seal the duct inlet and outlet. The baffle body 41 is also provided with multiple transverse reinforcing ribs 412 to increase the rigidity of the baffle body 41 and prevent breakage during movement. The edge of the baffle body 41 is provided with multiple evenly distributed openings 413, and the inner periphery of the frame 42 mates with the openings 413 of the baffle body 41 to facilitate installation of the baffle body 41.

[0088] In this embodiment, the frame 42 of the air duct baffle is made of rubber. The upper and lower end surfaces of the frame 42 and the side end surface away from the baffle shaft 411 are recessed inward to form a V-shaped groove 421, which is beneficial to the shock absorption and sealing of the air duct baffle.

[0089] Example 4

[0090] like Figure 7 、 Figures 15 to 18 As shown, this embodiment introduces a joint 5 for connecting the air duct to the crossbeam 2. The joint 5 is respectively placed and fixed in the hollow parts 8 at both ends of the air duct connecting crossbeam 2. A clamping hole 14 is provided in the joint 5. The motor 1 and the adapter 3 are respectively connected to the joint 5 through the clamping hole 14. The adapter 3 is connected to the first joint 21, and the motor 1 is connected to the second joint 22.

[0091] The connecting beam 2 in this embodiment includes a base plate 7 and a hollow portion 8. The hollow portion 8 is arranged at the left and right ends of the base plate 7. A joint 5 and a spring 6 are installed in the hollow portion 8 to connect the motor 1 and the connecting member 3 with the connecting beam 2.

[0092] The hollow portion 8 in this embodiment is arranged in a stepped shape along the axis, including a large-diameter portion and a small-diameter portion. The large-diameter portion has a larger diameter than the small-diameter portion, and the large-diameter portion cooperates with the connector 5. An outwardly protruding spring extension 15 is provided at one end of the hollow portion away from the small-diameter portion for mounting the spring 6.

[0093] The front portion of the connector 5 in this embodiment has an arc-shaped transition, with outwardly protruding fixed bosses 12 at the upper and lower ends of the middle portion. The front portion of the connector 5 is disconnected along the axial direction, and the front and rear portions of the fixed bosses 12 are each provided with two axially symmetrical claws to control the opening and closing of the front portion of the connector 5. The outer periphery of the connector 5 is recessed inward to form a groove 13. The groove 13 cooperates with the small-diameter portion of the hollow portion 8 to allow the connector 5 to be plugged into the base plate 7 through the groove 13.
