[0055] In the present invention, unless otherwise clearly specified and limited, terms such as "installed", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0056] Refer to Figures 1 - 10 , which is the first embodiment of the door body ejection assembly proposed by the present invention. A door body ejection assembly is used for the automatic ejection of the door body 30. The door body 30 is pivotally arranged on the door frame. The door body ejection assembly is preferably arranged on the door body 30 with a door lock 36. After the locking of the door lock 36 is released, the door body is automatically ejected under the action of the door body ejection assembly.
[0057] See Figure 4 and Figure 5 As shown in, a door body ejection assembly includes: a second ejection structure 20 and a mounting portion provided on the door body 30 or the door frame. The second ejection structure 20 is used to push the door body 30 to open. The second ejection structure 20 is fixedly installed on the mounting portion. The second ejection structure 20 can be installed on the door body 30 or on the door frame. A second mounting hole 201 is provided in the mounting portion, and the second ejection structure 20 passes through the second mounting hole 201; the second ejection structure 20 has a fixed base 21, a spring post 22, and a second elastic member 23. The second elastic member 23 is located between the fixed base 21 and the spring post 22, and the fixed base 21 is fixed on the mounting portion; the spring post 22 can telescopically move relative to the fixed base 21, and the spring post 22 passes through the second mounting hole 201; a guiding structure 202 for guiding the axial telescopic movement of the spring post 22 is provided on the mounting portion.
[0058] By setting up the door body ejection component, during the entire process of opening and closing the door body, the door body 30 will not be affected by the torsional spring elastic force, enabling the user to easily and conveniently rotate to open or close the door body 30. Only when the door body 30 is about to be latched and closed will the telescopic column 12 generate resistance. As the door body 30 closes, the telescopic column 12 is also compressed and in a retracted state, making the operation and feel of opening and closing the door body better. And by setting up the guiding structure, it is beneficial for the elastic column 22 to smoothly telescopically move axially along the guiding structure 202, avoiding the swaying of the elastic column 22 in the radial plane and being beneficial for the smooth movement of the elastic column. Directly setting the guiding structure 202 on the installation part is beneficial for simplifying the second ejection structure and improving the loading and unloading efficiency of the second ejection structure 20.
[0059] The elastic column 22 realizes axial telescoping under the limitation of the guiding structure 202 and the second installation hole 201. The elastic column 22 passes through the second installation hole 201. The size of the second installation hole 201 is set to match the outer size of the elastic column 22. The elastic column 22 extends out from the second installation hole 201. At the same time, the second installation hole 201 also plays a role in limiting the elastic column 22, increasing stability.
[0060] See Figures 9 - 10 As shown, for the structural setting of the guiding structure 202, the guiding structure 202 extends axially and is used to limit the elastic column 22. The guiding structure 202 can be set as a cylindrical shape, or an arc shape, or can be set as multiple guiding columns extending radially. It is preferably set as a circular guiding column. The fixed base 21 is fixed to the end of the guiding column by screws. The guiding structure 202 has a guiding function and also has the function of fixing the fixed base 21.
[0061] See Figure 6 As shown, at one end of the elastic column 22 close to the fixed base 21, there is an outwardly protruding guiding flange 221. The guiding flange 221 moves along the guiding column to realize the limit of the elastic column 22. The guiding flange 221 is arranged at one end close to the fixed base 21, which is beneficial for making the distance between the guiding flange 221 and the second installation hole 201 as large as possible. By limiting the elastic column 22 at two positions of the guiding flange 221 and the second installation hole 201, it is beneficial for ensuring the smooth telescopic movement of the elastic column 22. And through the guiding flange 221, it is beneficial for reducing the contact area between the elastic column 22 and the guiding structure 202, beneficial for minimizing the friction force as much as possible. And it is beneficial for increasing the radial dimension of the guiding structure 202, beneficial for the loading and unloading operation of the second ejection structure 20.
[0062] In this embodiment, the guiding structure 202 and the guiding flanging 221 are in linear contact; in other embodiments, the guiding structure 202 and the guiding flanging 221 may also be in surface contact. For example, when the guiding structure 202 and the guiding flanging 221 are in surface contact, an arc-shaped guiding notch is formed on the guiding flanging 221, and the guiding post is partially or entirely located in the guiding notch.
[0063] Refer to Figure 7 As shown, for the structure of the fixed base 21, the fixed base 21 has a flat plate-shaped base body 211, a fixed ear 212 extending outward along the base body 211, and a reinforcing rib 213 extending towards the elastic post 22; when the elastic post 22 retracts, the guiding flanging 221 abuts against the base body 211 to limit the retraction of the elastic post 22 to the in-place state.
[0064] Refer to Figures 11 - 21 This is the second embodiment of the door body ejection assembly proposed by the present invention. The main difference between this embodiment and the first embodiment is that a first ejection structure 10 is further provided and is matched with the second ejection structure 20. Other structures may be the same as those in the first embodiment.
[0065] The laundry treatment device may be a washing machine, a dryer, a washing and drying integrated machine, etc. In this embodiment, as Figure 1 shown, it is a drum washing machine. The laundry treatment device includes: a cabinet 100 and a door body 30. A clothes inlet is formed on the front panel of the cabinet 100. The door body 30 is pivotally arranged on the front panel so that the clothes inlet can be opened / closed. A door frame or a door body installation groove is provided on the front panel and is matched with the door body 30.
[0066] Refer to Figure 12 and Figure 13 As described, the door body ejection assembly further includes a second ejection structure 20. The first ejection structure 10 and the second ejection structure 20 cooperate to push the door body open. The first ejection structure 10 is arranged on one of the door body 30 or the door frame, and the second ejection structure 20 is arranged on the other of the door body 30 or the door frame; the first ejection structure 10 has a telescopic column 12 that can telescopically move, and the second ejection structure 20 has an elastic post 22 that can telescopically move. In the closed state of the door body 30, the telescopic column 12 and the elastic post 22 press against each other.
[0067] By setting up the door body ejection component, during the entire process of opening and closing the door body, the door body 30 will not be affected by the torsion spring elastic force, enabling users to easily and conveniently rotate to open or close the door body 30. Only when the door body 30 is about to be latched and closed will the telescopic column 12 generate resistance. As the door body 30 closes, the telescopic column 12 is also compressed and in a retracted state, making the operation and feel of opening and closing the door body better; by setting the first ejection structure 10 and the second ejection structure 20 to match, the ejection stroke of the ejection component is the sum of the strokes of the telescopic column 12 and the ejector pin 22, which is beneficial to increasing the ejection stroke and can automatically open the door body to a larger angle.
[0068] In the closed state of the door body 30, the first ejection structure 10 and the second ejection structure 20 are coaxial, and the radial dimension of the telescopic column 12 is larger than the radial dimension of the ejector pin 22; the first ejection structure 10 also has a housing 11 sleeved outside the telescopic column 12, and the housing 11 surrounds to form a cavity with an opening; in the closed state of the door body, the ejector pin 22 extends into the cavity to press against the telescopic column 12; it is beneficial for the cavity of the housing 11 to limit the telescopic movement of the ejector pin 22.
[0069] See Figures 14 - 17 As shown, the structure of the first ejection structure 10 is described. A first mounting hole 101 for mounting the first ejection structure 10 is provided on the front plate of the box body 100. The first ejection structure 10 is used to push the door body 30 to open and is installed at the first mounting hole 101, that is, the first ejection structure 10 can be installed on the door body 30 or on the door frame. Among them, the first ejection structure 10 has a housing 11 and a telescopic column 12. The housing 11 surrounds to form a cavity with an opening, and the telescopic column 12 is telescopically arranged in the cavity; an installation edge 111 extending outward is provided at the open end of the housing 11, and a plurality of elastic installation claws 112 are provided on the housing 11; after the first ejection structure 10 is installed into the first mounting hole 101, the edge of the first mounting hole 101 is clamped between the installation edge 111 and the installation claws 112; there is a gap between the installation edge 111 and the installation claws 112 for accommodating the edge of the first mounting hole 101.
[0070] By setting up the door body ejection component, during the entire process of opening and closing the door body, the door body 30 will not be affected by the torsion spring elastic force, enabling users to easily and conveniently rotate to open or close the door body 30. Only when the door body 30 is about to be latched and closed will the telescopic column 12 generate resistance. As the door body 30 closes, the telescopic column 12 is also compressed and in a retracted state, making the operation and feel of opening and closing the door body better; and by setting the installation edge 111 and the installation claws 112, it is beneficial for the installation operation of the door body ejection component to be simple, firm after fixation, and convenient for disassembly.
[0071] See Figure 14As shown, it is preferable to evenly distribute a plurality of mounting claws 112 in the circumferential direction of the outer shell 11. The mounting claws 112 can have elastic displacement in the radial direction of the first pop-up structure 10. The size of the first mounting hole 101 matches the outer size of the outer shell 11. Preferably, the outer shell 11 is set to be cylindrical, and the first pop-up structure 10 is installed by passing the outer shell 11 through the first mounting hole 101. By setting that the mounting claws 112 can be elastically deformed, it is used to realize the inward deformation of the mounting claws 112, so that the mounting claws 112 can pass through the first mounting hole 101. After the mounting claws 112 pass through the first mounting hole 101, they elastically reset, so that the mounting claws 112 are blocked at the edge of the first mounting hole 101; the mounting edge 111 is formed by extending outward, so the radial dimension of the mounting edge 111 is greater than the outer diameter of the outer shell 11, and the dimension outside the mounting edge 111 is greater than the first mounting hole 101; when the mounting edge 111 reaches the first mounting hole 101, the edge of the first mounting hole 101 blocks the mounting edge 111, and the outer shell 11 cannot continue to move along the mounting direction. At this time, the mounting claws 112 and the mounting edge 111 are respectively located on both sides of the edge of the first mounting hole 101, playing a role in fixing the outer shell 11; in this way, the installation operation of the first pop-up structure 10 is simple, and by applying pressure to the mounting claws 112 to realize radial inward deformation, disassembly can also be conveniently realized.
[0072] See Figure 16 As shown, the mounting claw 112 has a rod portion 1121 connected to the outer shell 11 and a claw portion 1122 close to the mounting edge 111. The thickness of the rod portion 1121 is less than the thickness of the claw portion 1122. The pressure applied to the mounting claw 112 acts on the claw portion 1122, which is beneficial to the deformation of the rod portion 1121 and also beneficial to increasing the force-bearing structural strength of the claw portion 1122. Here, the thickness refers to the radial dimension. Preferably, the distance between the outer side of the claw portion 1122 and the axis of the outer shell 11 is greater than the outer radius of the outer shell 11, that is, part or all of the claw portion 1122 protrudes outward from the outer shell 11; the distance between the outer side of the rod portion 1121 and the axis of the outer shell 11 is less than or equal to the outer radius of the outer shell 11, ensuring that the claw portion 1122 does not protrude from the outer shell 11. When the mounting claw 112 is subjected to pressure, the claw portion 1122 farthest from the connection end has the largest displacement; thus, the claw portion 1122 protrudes from the outer shell 11. In the case of force-induced deformation, the claw portion 1122 can not protrude from the outer shell 11; but the displacement of the rod portion 1121 is small, especially at the connection end with the outer shell 11. Therefore, setting that the claw portion 1122 does not protrude from the outer shell 11 is beneficial to ensuring the installation of the outer shell 11 into the first mounting hole 101.
[0073] The first pop-up structure 10 further includes a first elastic member 13 for realizing the pop-up of the telescopic column 12. The first elastic member 13 is located inside the cavity and is preferably set as a spring. After the door body 30 is closed, the telescopic column 12 compresses the first elastic member 13 and is in a retracted state. After the locking of the door body 30 is released, the first elastic member 13 pushes the telescopic column 12 to move, so that the door body 30 is pushed and popped open. The telescopic column 12 telescopically moves inside the cavity of the outer shell 11. To ensure the stability of the movement of the telescopic column 12, the telescopic column 12 matches the inner diameter of the outer shell 11, and the distance between the inner side of the claw portion 1122 and the axis of the outer shell 11 is equal to the inner radius of the outer shell 11. When the telescopic column 12 is located inside the claw portion 1122, even if an inward pressure is applied to the mounting claw 112, the pressure acts on the telescopic column 12 through the mounting claw 112, making the telescopic column 12 unable to deform. Therefore, when installing or disassembling the first pop-up structure 10, it is necessary to press the telescopic column 12 to move it in the retracting direction, that is, compress the first elastic member 13, so that the telescopic column 12 leaves the mounting claw 112, especially away from the claw portion 1122. When installing and disassembling the first pop-up structure 10, the distance that the telescopic column 12 moves towards the bottom of the outer shell 11 is preferably set to be greater than the stroke when the telescopic column 12 pops open the door body 30, that is, the pressure on the first elastic member 13 during installation and disassembly is greater than the pressure on the first elastic member 13 when the door body 30 is closed. After the first pop-up structure 10 is installed, the telescopic column 12 is located inside the mounting claw 112 to ensure the firmness after the outer shell 11 is fixed. The thickness of the rod portion 1121 is less than the wall thickness of the outer shell 11, and the distance between the outer side of the rod portion 1121 and the axis of the outer shell 11 is equal to the outer radius of the outer shell 11, so that the rod portion 1121 has a space for deformation within the wall thickness of the outer shell 11, which is beneficial to deforming the rod portion 1121 by pressing the claw portion 1122 during the installation and disassembly of the first pop-up structure 10.
[0074] The following describes the installation method of the first pop-up structure 10, including the following steps:
[0075] S100. Push the telescopic column 12 to move towards the bottom of the cavity, and then use a tool or finger to press the mounting claw 112 to move it inward, so that the mounting claw 112 prevents the telescopic column 12 from extending and moving;
[0076] S200. Push the end of the door body pop-up assembly opposite to the open end into the first installation hole 101. When the mounting claw 112 reaches the first installation hole 101 and is subjected to the inward pressure from the hole wall of the first installation hole 101, the pressure on the mounting claw 112 by the tool or finger can be released. Then continue to push the outer shell 11, so that the mounting claw 112 passes through the first installation hole 101 and resets. The edge of the first installation hole 101 is clamped between the mounting edge 111 and the mounting claw 112 to complete the installation.
[0077] For the disassembly method of the first pop-up structure 10, it includes the following steps:
[0078] S0100. Push the telescopic column 12 in the direction of the bottom of the cavity. Then, use a tool or finger to press the mounting claw 112 to move it inward, so that the mounting claw 112 prevents the telescopic column 12 from extending and moving.
[0079] S0200. Move the housing 11 in the direction of the open end. When the mounting claw 112 reaches the first mounting hole 101 and receives the inward pressure from the hole wall of the first mounting hole 101, the pressure on the mounting claw 112 by the tool or finger can be released. Then, continue to move the housing 11 in the direction of the open end until it is detached, completing the disassembly of the first ejection structure 10.
[0080] An inclined guiding transition surface 1123 is provided between the rod portion 1121 and the claw portion 1122 on the outer side of the mounting claw 112, which is used for guiding and transitioning when the claw portion 1122 passes through the first mounting hole 101, ensuring convenient and fast operation when the housing 101 is loaded and unloaded into the first mounting hole 101.
[0081] See Figures 14 - 16 As shown in the figure, the structure of the housing 11 is described. The housing 11 includes a cylinder 113 and a bottom cover 114. The bottom cover 114 is fixed to the bottom of the cylinder 113 through an annular hoop 115. The bottom cover 114 has a circular bottom cover plate 1141, and a plurality of spaced fixing plates 1142 are provided along the edge of the bottom cover plate 1141. The fixing plates 1142 extend towards the cylinder 113. A fixing groove matching the fixing plates 1142 is opened at the lower end of the cylinder 113. The fixing plates 1142 are located in the fixing groove, and the annular hoop 115 is located outside the fixing plates 1142 to realize the fastening of the cylinder 113 and the bottom cover 114.
[0082] A fastening groove is opened on the cylinder 113, and the annular hoop 115 is located in the fastening groove. By setting the fastening groove, the limit for the annular hoop 115 is formed, enhancing the firmness of fixation. The distance between the outer side of the fixing plate 1142 and the axis of the housing 11 is equal to the distance between the bottom of the fastening groove and the axis of the housing 11. The annular hoop 115 is also fastened outside the fixing plate 1142. A protruding stop portion 11421 is provided on the fixing plate 1142, and the stop portion 11421 cooperates with the annular hoop 115 to prevent the bottom cover 114 from detaching. The distance between the outer side of the stop portion 11421 and the axis of the housing 11 is equal to or less than the outer radius of the housing 11, avoiding the stop portion 11421 from blocking the housing 11 from passing through the first mounting hole 101.
[0083] On the bottom cover plate 1141 of the bottom cover 114, there is a protruding first cylindrical positioning portion 1143 that defines one end of the first elastic member 13. The first elastic member 13 is sleeved outside the first cylindrical positioning portion 1143. At one end of the first cylindrical positioning portion 1143 close to the bottom cover plate 1141, there is an outwardly protruding defining fixing rib 11431, and one end of the first elastic member 13 is sleeved and fixed outside the defining fixing rib 11431.
[0084] See Figures 15 - 17 As shown, the telescopic column 12 has a protruding column 123 that can extend out of the open end. The telescopic column 12 has a telescopic column body 121 that matches the cavity, a limiting platform 122 that bends inward along one end of the telescopic column body 121, and a protruding column 123 that extends away from the bottom cover 114 along the limiting platform 122. At the open end of the outer shell 11, there is a limiting edge 116 that extends inward. The limiting platform 122 and the limiting edge 116 cooperate to achieve limiting, and the protruding column 123 can extend out of the open end.
[0085] See Figures 18 - 21 As shown, the door body ejection assembly further includes a third ejection structure 50. The third ejection structure 50 has a telescopic ejection post 51 and a third elastic member 52 that pushes the ejection post 51 to extend. A third installation hole 501 for the ejection post 51 to extend is opened on the door body 30. The third elastic member 52 is located between the ejection post 51 and the hinge reinforcement plate 44. By providing the door body ejection assembly, during the entire process of opening and closing the door body, the door body 30 is not affected by the torsion spring elastic force, enabling the user to easily and conveniently rotate to open or close the door body 30. Only when the door body 30 is about to be buckled and closed will there be resistance, and the operation and feel of opening and closing the door body 30 are better. The hinge reinforcement plate 44 is used to block the third elastic member, omitting the outer shell sleeved outside, which is beneficial to the simplicity of the third ejection structure.
[0086] An outwardly extending retaining edge 511 is provided at the end of the ejection post 51. The size of the retaining edge 511 is larger than the size of the third installation hole 501. When the ejection post 51 pops out under the action of the third elastic member 52, when the retaining edge 511 reaches the third installation hole 501, the extension of the ejection post 51 reaches the maximum. The retaining edge 511 and the third installation hole 501 cooperate to define the maximum extended state of the ejection post 51.
[0087] The hinge reinforcement plate 44 is provided with a support platform 448 extending towards the ejector post 51. The end of the third elastic member 52 is located on the support platform 448. The support platform 448 has a cylindrical side surface 4481 extending along the hinge reinforcement plate 44 and a support surface 4482 at the top. The support surface 4482 is a circular plane. By providing the support platform 448, it is beneficial to increase the structural strength and ensure the support for the third elastic member 52. The retaining edge 511 at the end of the ejector post 51 cooperates with the support surface 4482 to define the maximum retracted state of the ejector post 51. When the door body 30 is closed, the box body 100 applies a pressure to retract the ejector post 51, causing the ejector post 51 to retract towards the support platform 448. At the same time, the third elastic member 52 is compressed. After the retaining edge 511 contacts the support surface 4482, due to the blocking of the support surface 4482, the ejector post 51 can no longer retract and reaches the maximum retracted state.
[0088] When the door body 30 is opened, the ejector post 51 extends under the action of the third elastic member 52. When the door body 30 is closed, the ejector post 51 retracts and moves under the extrusion of the front plate of the box body 100. When the ejector post 51 expands and contracts, the retaining edge 511 of the ejector post 51 must move between the third mounting hole 501 and the hinge reinforcement plate 44. Specifically, the retaining edge 511 moves between the third mounting hole 501 and the support surface 4482 of the support platform 448.
[0089] In this embodiment, the first ejection structure 10 is provided on the front plate, and the second ejection structure 20 is provided on the door body. The first ejection structure 10 and the second ejection structure 20 are provided near the door lock 36. The third ejection structure 50 is provided near the hinge. Preferably, two symmetrically arranged third ejection structures 50 are provided on the door body 30. The two third ejection structures 50 are symmetrically arranged with respect to a plane passing through the axis of the door body and perpendicular to the rotation axis of the door body, which is beneficial to ensure that the two third ejection structures 50 are located on both sides of the hinge member, beneficial to the force balance of the door body, and beneficial to the opening of the door body.
[0090] In other embodiments, the door body ejection assembly may be the first ejection structure 10 provided on the front plate or the door body 30, or the second ejection structure 20 provided on the front plate or the door body 30, or the third ejection structure 50 provided on the front plate or the door body 30, or the first ejection structure 10 is provided on one of the door body 30 or the front plate, and the second ejection structure 20 is provided on the other of the door body 30 or the front plate.
[0091] The door body 30 includes a transparent basin 31, an inner door frame 32, an outer door frame 33, and an observation screen 34. The transparent basin 31 is in a basin shape with an open front side. The hinge reinforcement plate 44 is fixed to the front side of the inner door frame 32. The hinge reinforcement plate 44 plays a role in increasing the structural strength of the door body and also serves to fix the transparent basin 31. The hinge reinforcement plate 44 is a plate-like integral structure fixed to the inner door frame 32, sharing the stress for the structure of the inner door frame 32 around the hinge axis and protecting the plastic inner door frame 32.
