It should be noted that these drawings and the description of characters are not intended to limit the scope of the concept of the present invention in any way, but are for explaining the concept of the present invention to those skilled in the art with reference to specific embodiments.

In order to clarify the purpose, technical solution and advantages of the embodiments of the present invention, the technical solutions of the embodiments will be described clearly and briefly below. The following examples are for explaining the present invention and do not limit the scope of the present invention.

As shown in FIGS. 1 to 18, the embodiment of the present invention describes a push-type detergent case mounted on a washing machine. The push-type detergent case includes a tank 200 attached to a washing machine housing 300, and a detergent case 100 that can be taken in and out is attached to the inside of the tank 200. A push lock unit 700 is provided between the tank 200 and the detergent case 100. By applying a push force to the detergent case to change the locked state of the push lock unit 700, the tank 200 and the detergent case 100 are locked or unlocked. Between the tank 200 and the detergent case 100, there is further provided an elastic force unit 600 that gives power for pushing out the detergent case. A slide rail structure is provided between the tank 200 and the detergent case 100, and the detergent case is opened and closed by pushing and pulling along the slide rail structure. The slide rail structure includes a plurality of pulleys 1 that are in contact with the detergent case 100 so as to reduce friction during a process of loading and unloading the detergent case.

In the embodiment of the present invention, the user pushes the detergent case 100 into the tank 200 along the sliding path structure and then applies a push force to the detergent case 100 to change the push lock unit 700 to the locked state. .. As a result, the detergent case 100 is locked in the tank 200, and the detergent in the detergent case 100 can be added as water is supplied to the washing machine. When it is necessary to replenish the detergent case 100 with detergent, the user applies a push force again to the detergent case 100 locked in the tank 200 to change the push lock unit 700 to the unlocked state. At this time, since the elastic force unit 600 gives the pushing force to the outside to the detergent case 100, the detergent case 100 is pushed out of the tank 200 by the action of the pushing force while being assisted by the pulley 1 having a small frictional force along the slide rail structure. Be done. In this way, the purpose of automatically opening and locking the detergent case by the push force is realized.

By installing a detergent case that is controlled by a push lock and is given extrusion force from the elastic force unit to the washing machine, the detergent case can be used for automatic lock and push release with only a small push force. Become. As a result, the detergent case has a push-type opening/closing function. In addition, by mounting the detergent case in the tank through the slide rail structure that cooperates with the pulley, the displacement friction of the detergent case changes into sliding friction, and thus the friction force in the process of pulling out the detergent case is reduced. As a result, the smoothness in the process of pushing the detergent case is improved.

As shown in FIGS. 1 to 12, in this embodiment, a push-type detergent case will be described. The push-type detergent case includes a tank 200 attached to a washing machine housing 300, and a detergent case 100 that can be taken in and out is attached to the inside of the tank 200. A slide rail structure is provided between the tank 200 and the detergent case 100. The slide rail structure includes a plurality of pulleys 1 that are in contact with the detergent case 100 so as to reduce friction in the process of taking the detergent case 100 in and out.

By mounting the detergent case and the tank via the pulley and slide rail structure, the friction at the displacement contact point between the detergent case and the tank changes from sliding friction to rolling friction. Drastically reduced.

In the present embodiment, pulley guide grooves 6 are provided on both the left and right sides of the detergent case 100, the pulley guide grooves 6 extending in a direction parallel to the axis of the detergent case 100 and having an open lower end. On the inner wall of the tank 200, a plurality of pulleys 1 each having a pulley surface provided in the axial direction of the pulley guide groove 6 are mounted. The upper portion of the pulley 1 extends into the pulley guide groove 6 and contacts the ceiling wall of the pulley guide groove 6.

By supporting the pulley guide groove mounted on the detergent case with a plurality of pulleys mounted on the tank, a plurality of supporting points are provided for the detergent case, and thus stability in the pushing and pulling process of the detergent case is improved. .. Also, by mounting multiple pulleys installed in the same direction in the slide rails of the detergent case, the pulleys and slide rails come into contact with each other so as to regulate the position of each other, preventing the problem of deviation in the pushing and pulling process of the detergent case. To be done. Further, since the deviation correction force is applied to the detergent case, the detergent case is prevented from falling off.

In this embodiment, the left and right side walls of the tank 200 are provided with bent portions 11 that are bent horizontally toward the inside. The bent portion 11 is provided below the pulley guide groove 6. The bending portion 11 is provided with a plurality of mounting grooves 9 installed at intervals, and the pulleys 1 provided vertically are mounted in the respective mounting grooves 9. The central axis 10 of the pulley 1 is perpendicular to the axial direction of the pulley guide groove 6. As a result, the pulleys 1 are mounted on the same horizontal plane, and the vertically mounted pulleys 1 are located on the same vertical plane below the pulley guide groove 6. Therefore, the purpose of imparting a vertical supporting force and a sliding frictional force in the horizontal pushing/pulling process to the pulley guide groove 6 is achieved by each pulley 1.

In this embodiment, a central shaft 10 is provided at the center of the pulley 1. The central shaft 10 is attached to the tank 200 horizontally and rotatably around the shaft. The central axis 10 is perpendicular to the push-pull movement direction of the detergent case 100, that is, the axial direction of the pulley guide groove 6. As a result, when the pulley 1 rotates about the central axis 10, the outer periphery of the pulley 1 rotates in the axial direction of the pulley guide groove 6, thereby guiding the detergent case 100 to perform push-pull movement, thereby reducing friction. The purpose of lowering is realized.

In this embodiment, the central axis of the pulley 1 may be provided independently. The central shaft 10 extends horizontally through the center of the pulley 1, and both ends of the central shaft 10 are inserted into the left and right side walls of the mounting groove 9, respectively. The pulley 1 may rotate about the axis of the central axis 10 with respect to the central axis 10, and/or both the pulley 1 and the central axis 10 may rotate about the axis of the central axis 10. This realizes the purpose of rotating the outer periphery of the pulley with respect to the tank and reducing friction at the contact point between the pulley and the slide rail.

Alternatively, in this embodiment, the central shaft 10 and the pulley 1 may be provided as an integral member. The left and right ends of the central shaft 10 project from the left and right of the pulley 1 and are rotatably inserted into the left and right side walls of the mounting groove 9. In this case as well, the purpose of similarly rotating the outer periphery of the pulley 1 with respect to the tank 200 and reducing the friction at the contact portion between the pulley 1 and the pulley guide groove 6 can be realized.

In this embodiment, since the central portion of the pulley 1 is in close contact with the left and right side walls of the mounting groove 9, the pulley 1 is horizontally restricted by the left and right side walls of the mounting groove 9. This prevents the pulley 1 from moving in the horizontal direction, so that the stability of contact between the outer periphery of the pulley 1 and the pulley guide groove 6 is improved. Further, the outer periphery of the pulley 1 and the left and right side walls of the pulley guide groove 6 are separated from each other with a space. As a result, contact between the pulley 1 and the side wall of the pulley guide groove 6 is avoided, and thus the degree of horizontal contact between the pulley 1 and the pulley guide groove 6 is reduced. Therefore, the frictional force is reduced, and the smoothness of the rotation of the pulley 1 in the pulley guide groove 6 is improved. Further, the outer periphery of the pulley 1 and the ceiling wall of the pulley guide groove 6 are in close contact with each other. The close contact between the outer periphery of the pulley 1 and the ceiling wall of the pulley guide groove 6 ensures the reliability of the support of the pulley guide groove 6 by the pulley 1.

As shown in FIG. 4 and FIG. 5, in the present embodiment, the pulley 1 is provided at the center thereof with position regulating projections that respectively project to the left and right sides in the axial direction. The outer side surfaces of the position regulation projections on both sides are vertical surfaces that come into contact with the left and right side walls of the mounting groove 9 so as to be regulated in position. As a result, the left and right sides of the pulley 1 and the left and right side walls of the mounting groove 9 are in surface contact with each other, so that the positions of the two are reliably regulated and deviation of the pulley in the axial direction is prevented.

As shown in FIGS. 4 and 5, in the present embodiment, the outer periphery of the pulley 1 is provided with bent portions that are bent horizontally to the left and right sides in the axial direction. The outer surface of the bent portion in the radial direction of the pulley 1 is a cylindrical surface that is provided horizontally along the axis of the pulley 1. The cylindrical surface comes into close contact with the ceiling wall of the pulley guide groove 6. As a result, the outer periphery of the pulley 1 and the ceiling wall of the pulley guide groove 6 are in intimate surface contact with each other, so that the stability of transmission with the pulley guide groove 6 during the rotation process of the pulley 1 and the pulley 1 and the pulley guide groove The certainty of contact and support with 6 is guaranteed.

Preferably, in this embodiment, the bent portions 11 on the left and right sidewalls of the tank 200 are horizontally provided on the same height surface. This ensures that the support planes on the left and right sides of the detergent case 100 are located on the same horizontal plane, so that the detergent case 100 is effectively prevented from tilting in the left-right direction.

In the present embodiment, the outside of the bent portion 11 is connected to the first vertical portion 12 which vertically extends upward. The inner side of the bent portion 11 is connected to the second vertical portion 13 that vertically extends downward. The first vertical portion 12 is provided corresponding to the outside of the pulley guide groove 6, and the second vertical portion 13 is provided corresponding to the side wall of the detergent case 100. As a result, the inner wall of the tank 200 and the outer wall of the detergent case 100 come into contact with each other as closely as possible, and the tank 200 regulates the position of the detergent case 100 in the horizontal direction. Therefore, the occurrence of deviation in the pushing and pulling process of the detergent case 100 is avoided.

As shown in FIGS. 1 to 12, in this embodiment, a push-type detergent case will be described. The push-type detergent case includes a tank 200 that is attached to a washing machine housing, and a detergent case 100 that can be taken in and out is attached to the inside of the tank 200. On the ceiling of the detergent case 100, a hanging upper lid 500 is provided. On the ceiling wall of the tank 200, a plurality of position regulating pulleys 14 mounted vertically and mounted so as to project from the lower surface of the ceiling wall are attached. This reduces friction in the process of taking in and out the detergent case 100.

By providing a plurality of position regulation pulleys between the upper lid of the detergent case and the ceiling wall of the tank, direct contact between the upper lid of the detergent case and the ceiling wall of the tank is avoided. In the process of pushing and pulling the detergent case, a sliding frictional force is applied from the position regulation pulley to the upper lid of the detergent case, so that the friction at the displacement contact point between the upper lid of the detergent case and the tank changes from sliding friction to rolling friction. As a result, the frictional force during the pushing and pulling process of the detergent case is significantly reduced.

In this embodiment, a plurality of reverse mounting grooves 9 are provided on the ceiling wall of the tank 200. In each of the mounting grooves 9, a vertically provided position regulating pulley 14 is mounted. Further, the central axis 10 of the position regulation pulley 14 is perpendicular to the push-pull movement direction of the detergent case 100. As a result, rotation around the axis along the push-pull direction is generated on the outer periphery of the position regulation pulley 14. In the process of pushing and pulling the detergent case 100, the position regulation pulley 14 rotates accordingly, and sliding friction is imparted to the upper lid 500 of the detergent case 100 by the rotating position regulation pulley 14. Therefore, the purpose of reducing the frictional force in the pushing and pulling process is realized.

In the present embodiment, a central shaft 10 is provided at the center of the position regulating pulley 14. The central shaft 10 is attached to the tank 200 horizontally and rotatably around the shaft.

In this embodiment, the central shaft 10 of the position regulating pulley 14 may be provided independently. The center shaft 10 extends horizontally through the center of the position regulating pulley 14, and both ends of the center shaft 10 are inserted into the left and right side walls of the mounting groove 9, respectively. The position regulating pulley 14 may rotate around the axis of the central axis with respect to the central axis 10, and/or the position regulating pulley 14 and the central axis 10 may both rotate around the axis of the central axis 10. .. As a result, the outer periphery of the position regulating pulley 14 rotates with respect to the tank 200, and the purpose of reducing the friction at the contact point between the position regulating pulley 14 and the upper lid of the detergent case 100 is realized.

Alternatively, in this embodiment, the central shaft 10 and the position regulation pulley 14 may be provided as an integral member. The left and right ends of the central shaft 10 project from the left and right of the position regulating pulley 14 and are rotatably inserted into the left and right sidewalls of the mounting groove 9. Also in this case, similarly, the outer periphery of the position regulation pulley 14 rotates with respect to the tank 200, and the purpose of reducing the friction at the contact portion between the position regulation pulley 14 and the upper lid of the detergent case 100 can be realized.

In this embodiment, the central portion of the position regulating pulley 14 comes into close contact with the left and right side walls of the mounting groove 9. The bottom of the position regulating pulley 14 is exposed from the lower opening of the mounting groove 9 in the opposite direction, and the outer periphery of the position regulating pulley 14 projects from the ceiling wall of the tank 200. As a result, the position regulation pulley 14 comes into sliding contact with the upper lid of the detergent case 100. Further, due to the action of the position regulating pulley 14 provided so as to project, direct contact between the upper lid of the detergent case 100 and the ceiling wall of the tank 200 is effectively avoided. As a result, the friction method at the contact point between the upper lid of the detergent case 100 and the ceiling wall of the tank 200 becomes sliding friction provided by the position regulating pulley.

In this embodiment, position regulating protrusions are provided at the center of the position regulating pulley 14 so as to respectively project to the left and right sides in the axial direction. The outer side surfaces of the position regulation projections on both sides are vertical surfaces that come into contact with the left and right side walls of the mounting groove 9 so as to be regulated in position. As a result, the left and right sides of the position control pulley 14 and the left and right side walls of the mounting groove 9 are in surface contact with each other, so that the positions of both are surely controlled, and deviation of the position control pulley in the axial direction is prevented. To be done.

In this embodiment, the position regulating pulley 14 is provided on its outer periphery with bent portions that are bent horizontally to the left and right sides in the axial direction. The outer surface of the bent portion in the radial direction of the outer periphery of the position regulation pulley 14 is a cylindrical surface that is provided horizontally along the axis of the position regulation pulley 14. The cylindrical surface is in sliding contact with the upper lid 500 of the detergent case. As a result, the possible contact between the outer periphery of the position regulation pulley 14 and the upper lid 500 of the detergent case is a surface contact in which they are in close contact with each other, so that the stability of transmission of the position regulation pulley 14 to the upper lid of the detergent case 100 during the rotation process. Also, the reliability of contact and support between the position regulation pulley 14 and the upper lid of the detergent case 100 is guaranteed.

Preferably, in the present embodiment, the lower ends of the position regulating pulleys 14 are separated from the upper lid 500 of the detergent case by a certain gap. This effectively avoids contact between the upper lid 500 of the detergent case and other members, and prevents the upper lid 500 from being rubbed during the pushing and pulling process of the detergent case 100. Further, when the detergent case 100 is displaced in the vertical direction and the upper lid 500 of the detergent case comes into contact with other members (mainly the ceiling wall of the tank 200), the detergent case 100 is provided so as to project downward from the ceiling wall of the tank 200. Due to the function of the position regulation pulley 14, the upper lid 500 of the detergent case contacts only the position regulation pulley 14. Therefore, only sliding friction is generated on the upper lid 500 of the detergent case, and the frictional resistance during the pushing and pulling process of the detergent case 100 is effectively reduced.

In the present embodiment, at least two rows of position regulating pulleys 14 are provided on the ceiling wall of the tank 200, and a plurality of position regulating pulleys 14 are arranged in each row at intervals in the push-pull movement direction of the detergent case 100. Is included. The two rows of position regulating pulleys 14 are provided above the corresponding left and right sides of the detergent case 100, respectively. Preferably, the two rows of position regulation pulleys 14 are provided symmetrically with respect to the axis of the detergent case 100.

By providing two rows of position regulating pulleys on the left and right sides of the detergent case, the left and right sides of the upper lid of the detergent case are slid and regulated through the position regulating pulleys. As a result, the left and right sides of the upper lid of the detergent case are effectively regulated and supported, so that the vertical inclination on the left and right sides of the detergent case is avoided. Further, by providing a plurality of position regulating pulleys arranged at intervals in the left and right two rows, the respective positions of the detergent case are effectively regulated. Therefore, sliding detergent friction is effectively applied in all directions of the detergent case, and the stability of the detergent case in the pushing/pulling opening/closing process is improved.

As shown in FIGS. 1 to 3 and FIGS. 13 to 18, in this embodiment, a push lock applied to the push type detergent case of the present invention will be described. The push lock includes a latch 4 and a push lock body 5. The latch 4 is operably inserted into the push lock body 5. A cam 7 is mounted in the push lock body 5. Further, the cam 7 is provided with a groove for engaging and locking the lock hook 21 at the end of the latch 4. A lock catch elastic piece 8 is further mounted in the push lock body 5. One end of the lock catch elastic piece 8 is fixed to the push-lock main body 5 so as to lock or unlock the rotational movement of the cam 7, and the lock catch 24 that engages with the lock catch sliding path of the cam 7 is provided at the other end. It is provided.

In the present embodiment, a first projection 19 and a second projection 20 are provided on the outer circumference of the cam 7 so as to project in the radial direction. The gap between the first protrusion 19 and the second protrusion 20 forms a concave groove that engages with the lock hook 21 at the end of the latch 4.

As shown in FIG. 14, in the present embodiment, the end portion of the latch 4 comes into contact with the first protrusion 19 so as to be positionally regulated. A lock hook hole 22 into which the second protrusion 20 is inserted is provided at the end of the latch 4. As a result, when the latch 4 moves toward the inside of the push-lock main body 5 by the action of the push-lock force, the first protrusion 19 is pushed by the latch to rotate the cam 7. Then, the second protrusion 20 is inserted into the lock hook hole 22 at the end of the latch 4, and the lock hook 21 at the end of the latch 4 engages in the concave groove between the first protrusion 19 and the second protrusion 20. Further, since the lock catch 24 is locked by the cam 7 and the further rotation of the cam 7 is avoided, the push lock unit 700 is in the locked state.

As shown in FIG. 13, in the present embodiment, when the latch 4 again moves toward the inside of the push lock body 5 by the action of the push lock force, the first protrusion 19 is pushed by the latch 4 and the cam 7 is rotated again. Let Then, the lock between the lock catch 24 and the cam 7 is released and the cam 7 is in a free state, and the recovery force (preferably, the recovery force is the torsion spring attached to the cam so that the cam moves in the direction to push the latch). (Applied by) causes the latch to move toward the outside of the push-lock body. At this time, since the cam rotates in the opposite direction, the second protrusion 20 separates from the lock hook hole 22 at the end of the latch 4, and the lock hook 21 at the end of the latch 4 is located between the first protrusion 19 and the second protrusion 20. Slide out from the groove. As a result, the push lock unit is unlocked.

In this embodiment, the latch 4 and/or the cam 7 are provided with a position recovery drive structure. The position recovery drive structure applies a recovery force to the latch 4 and/or the cam 7 to push the latch 4 toward the outside of the push lock body 5. Preferably, the cam 7 is provided with a torsion spring. When the cam 7 and the lock catch 24 are locked, the torsion spring is in a tensioned state, and the cam 4 is rotated in the opposite direction to push the latch 4 toward the outside of the push-lock body 5. Adds resilience to move. On the other hand, when the cam 7 is disengaged from the lock catch 24, the torsion spring becomes free.

When the second protrusion 20 is inserted into the lock hook hole 22 at the end of the latch 4 and the lock hook 21 at the end of the latch 4 engages in the groove between the first protrusion 19 and the second protrusion 20, the lock catch 24 Locks the cam 7 so that the cam 7 cannot rotate. At this time, since the recovery force applied from the torsion spring cannot withstand the lock force of the lock catch 24, the push lock body 5 and the latch 4 are not unlocked. When the lock catch 24 releases the lock with the cam 7 and the cam 7 becomes freely rotatable, the cam 7 is rotationally driven in the opposite direction by the recovery force applied from the torsion spring. As a result, the latch 4 is pushed and moves in the direction in which it is separated from the push lock body 5, so that the latch 4 and the push lock body 5 are separated.

In this embodiment, a third protrusion 23 is provided on the outer peripheral surface of the cam 7. The third protrusion 23 constitutes a lock catch sliding path that regulates the sliding displacement of the lock catch 24 at the end of the lock catch elastic piece 8. The lock catch slide path includes a slide lock surface a, a lock catch groove surface b, and a slide lock release surface c, which are continuous from the beginning.

In the initial state in which the cam 7 freely rotates (see FIG. 15), when a push force is applied to the latch 4, the cam 7 is rotationally driven so that the lock catch 24 in the free state moves along the sliding lock surface a. It moves and slides into the lock catch groove surface b from the first end (see FIG. 16). As a result, the lock catch 24 at the end of the lock catch elastic piece 8 locks the cam 7. Then, when the push lock force is applied again, the cam 7 is rotationally driven again, and the lock catch 24 slides out of the lock catch groove surface b from the second end (see FIG. 17). Then, by the action of the recovery force, the cam 7 is driven to rotate in the opposite direction by a certain angle, so that the lock catch 24 moves along the sliding lock releasing surface c until it becomes a free state (see FIG. 18). As a result, the position of the cam 7 is restored to the initial state in which it can freely rotate.

In this embodiment, the third protrusion 23 extends along the circumferential direction of the cam 7. One end of the third protrusion 23 is a free end that restricts the separation of the lock catch elastic piece from the lock catch, and the other end is provided with a lock groove that is recessed inward so that the lock catch 24 can be slid and locked. ing. The inner wall of the lock groove constitutes a sliding lock surface b. One side surface of the third protrusion 23 is an inclined surface that gradually inclines outward from the free end in the lock groove direction, and the inclined surface forms a sliding lock surface a. The other side of the third protrusion is a slope that gradually increases from the lock groove toward the free end, and the slope forms a slide lock release surface c.

In the present embodiment, the push-lock body whose central portion of the lock catch elastic piece 8 is close to the slide lock releasing surface c via the return spring 18 so that the elastic force for position recovery is applied to the lock catch elastic piece 8. 5 is connected to one side. Due to the elastic force for position recovery, the lock catch 24 of the lock catch elastic piece 8 is displaced from the slide lock surface a toward the slide lock release surface c.

In the present embodiment, the lock groove includes an "L"-shaped path formed of an axial portion and a circumferential portion. The axial portion extends in a direction parallel to the axial direction of the pulley. The open end of the axial portion is connected to the slide lock surface a, and the other end is connected to one end of the circumferential portion. The circumferential portion extends from the axial portion in a direction away from the free end of the third protrusion 23. Further, the open end of the axial portion is connected to the slide lock surface b. Preferably, a guide stop rib is provided at the open end of the axial portion. One end of the guide stop rib is connected to the upper side of the opening end of the axial portion. Further, the other end is bent and then extends along the radial direction of the cam, and is separated from the other side at the opening end of the axial portion by a certain gap. This guarantees that the lock catch does not slide in the lock groove from the gap through the opening end of the axial portion and cannot slide in the opposite direction. More preferably, one side of the circumferential portion is directly configured by the slide lock releasing surface c so as to restrict the position and stop the stop rib. As a result, the stopper rib slides along the circumferential portion of the lock groove and slides out from the open end of the circumferential portion.

Preferably, one side in the radial direction of the lock groove is a slope inclined from the center toward both ends toward the inside of the lock groove so that the lock catch can easily slide in and out of the lock groove.

Preferably, in the present embodiment, the cam is provided with the fourth protrusion 25. The fourth protrusion 25 is provided between the second protrusion 20 and the third protrusion 23. At least a part of the fourth protrusion 25 and the latch 4 interfere with each other in the vertical plane and overlap each other. When the latch 4 pushes the cam 7 to rotate to a certain angle, the fourth protrusion 25 interferes with and contacts the latch 4. This prevents the rotation angle of the cam 7 from becoming excessively large, so that the situation in which the cam 7 excessively rotates and falls out due to the excessive pushing force of the latch 4 is avoided.

In the present embodiment, one end of the lock catch elastic piece 8 is fixedly attached to the push lock body 5 by a mounting bolt 26. Since the lock catch elastic piece 8 can generate relative elastic rotation and/or displacement, the lock catch 24 at the other end of the lock catch elastic piece 8 moves along the lock catch sliding path as the cam 7 rotates. Moving.

In this embodiment, the lock catch elastic piece 8 is provided so as to be inclined from the lower side to the upper side. Further, the lower end is fixedly attached to the push-lock main body 5 by a mounting bolt 26 that extends through and is perpendicular to the axis. A lock catch 24 is provided at the upper end and is perpendicular to the axis that bends downward.

By attaching the end of the lock catch elastic piece to the push-lock main body with a mounting bolt, the lock catch elastic piece can rotate around the axis of the bolt. As a result, the lock catch at the other end of the elastic piece can rotate about the axis of the bolt and can be displaced by elastic swing of the bolt in the axial direction. Therefore, the lock catch at the end of the elastic piece is easily displaced and moved along the position-regulating sliding path formed by the third protrusion.

The specific operation process of the push lock is as follows.

In the initial state, the push lock is unlocked. At this time, the lock catch 24 is located at the free end of the third protrusion, and the cam is in the free state.

As shown in FIG. 15, when a push force is applied to the latch 4, the latch 4 pushes the cam 7 to rotate the cam 7 counterclockwise. Then, the lock catch 24 moves in the lower end direction of the third protrusion 23 from the free state position of the upper end of the third protrusion 23 to the lower end of the slide lock face a along the sliding lock face a formed by the slope. And move. Then, due to the action of the return spring 18, the lock catch 24 moves to the lower end of the third protrusion 23.

As shown in FIG. 16, the lock catch 24 slides into the lock groove from the opening end in the axial direction portion of the lock groove and is positioned on the lock catch groove surface b formed by the inner wall of the lock groove. At this time, the lock hook 21 at the end of the latch 4 is located in the groove between the first protrusion 19 and the second protrusion 20, and the second protrusion 20 is inserted into the lock hook hole 22. As a result, the push lock is locked, and the lock catch 24 and the cam 7 are locked and engaged. As a result, the recovery force applied from the elastic force unit 600 to the push-lock main body 5 is resisted, and the rotation of the cam 7 which causes the position recovery in the clockwise direction is avoided. Therefore, the situation in which the push-lock main body 5 moves in the direction in which it is separated from the latch 4 is prevented.

As shown in FIG. 17, when the push force is applied to the latch 4 again, the latch 4 pushes the cam 7 again so that the cam 7 rotates counterclockwise. As a result, the lock catch 24 moves along the circumferential portion of the lock groove toward the open end of the circumferential portion.

As shown in FIG. 18, the lock catch 24 slides out from the open end of the lock groove in the circumferential direction. Then, by the action of the return spring 18, the lock catch 24 is pulled toward the lower end of the slide lock releasing surface c. Further, the cam 7 moves clockwise by the action of the recovery force applied from the torsion spring. As a result, the lock catch 24 moves toward the upper end of the third protrusion 23 along the sliding lock release surface c until it returns to the initial state.

As shown in FIGS. 1 to 18, in this embodiment, a push-type detergent case 100 will be described. The push-type detergent case includes a tank 200 attached to a washing machine housing 300, and a detergent case 100 that can be taken in and out is attached to the inside of the tank 200. A push lock unit 700 is further provided between the tank 200 and the detergent case 100. By applying a pushing force to the detergent case 100 to change the lock state of the push lock unit 700, the tank 200 and the detergent case 100 are locked or unlocked.

By installing a detergent case that is controlled by push-lock and is given extrusion force from the elastic force unit to the washing machine, the detergent case can be used for automatic lock and push-release with only a small push force. Become. As a result, the detergent case has a push-type opening/closing function.

In this embodiment, the detergent case 100 is provided with the latch 4, and the tank 200 is provided with the push-lock main body 5 provided corresponding to the latch 4. When the detergent case 100 is pushed into the tank 200 and a push force is applied, the latch 4 extends into the push lock body 5 and is locked. When the push force is applied again, the lock between the latch 4 and the push lock body 5 is released. This achieves the purpose of controlling the locking or unlocking of the detergent case 100 only by applying a pushing force to the detergent case 100.

In this embodiment, a knob 400 is provided at the tip of the detergent case 100. The knob 400 is equipped with a latch 4 that extends horizontally in the direction of the tank 200. A push lock body 5 is attached to the tank 200. Since the lock hole is provided in the push lock body 5 so as to correspond to the latch 4, when the detergent case 100 is pushed into the tank 200, the latch 4 extends into the push lock body 5 from the lock hole. Then, by the action of the push force, the latch 4 and the lock mechanism in the push lock body 5 are locked or unlocked.

In this embodiment, the push lock attached to the structure of the push-type detergent case 100 is the push lock described in the third embodiment. The push lock body 5 described in the third embodiment is mounted on the tank 200. Further, the latch 4 described in the third embodiment is attached in correspondence with the knob 400 at the tip of the detergent case 100. As a result, the latch 4 is correspondingly inserted into the push-lock main body 5, so that the purpose of locking or unlocking the latch 4 and the push-lock main body 5 is realized. Preferably, the outer circumference of the knob is provided so as to protrude from the detergent case, and the latch is attached to the protruding portion on the lower side of the knob. Further, the push lock body 5 is mounted so as to correspond to the lower side of the lower side wall of the tank 200. As a result, when the entire detergent case 100 is pushed so as to correspond to the tank 200, the latch 4 at the tip of the detergent case 100 is correspondingly inserted into the push lock body 5, and these locks are realized.

As shown in FIGS. 1 to 12, in this embodiment, a push-type detergent case 100 will be described. The push-type detergent case includes a tank 200 attached to a washing machine housing 300, and a detergent case 100 that can be taken in and out is attached to the inside of the tank 200. Between the tank 200 and the detergent case 100, an elastic force unit 600 that gives power for pushing out the detergent case 100 is provided.

By providing the elastic force unit between the detergent case and the tank, when a pushing force is applied to the detergent case, the detergent case moves toward the outside of the tank. Therefore, after the push lock provided on the push-type detergent case is released, the detergent case is automatically pushed out of the tank by the elastic force applied from the elastic force unit. This achieves the purpose of automatically opening the detergent case.

One end of the push lever 16 that is inserted into the push lever sleeve 15 is an insertion end. The insertion end is provided with a mounting portion that projects outward in the radial direction. The outer periphery of the mounting portion closely contacts the inner wall of the push lever sleeve 15. A compressed spring 17 is provided between the mounting portion and the sealed end of the push lever sleeve 15. Since the radial diameter of the opening of the push lever sleeve 15 is smaller than the outer diameter of the mounting portion, the push lever 16 is prevented from falling off.

In this embodiment, a damping unit is provided between the pushing lever sleeve 15 and the pushing lever 16. As a result, the damping force with respect to the relative displacement between the push lever 15 and the push lever sleeve 16 is strengthened, so that speed adjustment when the detergent case is pushed open is realized.

In this embodiment, at least one elastic force unit 600 is mounted on each of the left and right sides of the rear end of the detergent case 100. This ensures that the left and right sides of the detergent case 100 are uniformly received in the process of pushing and pulling, so that the displacement of the detergent case 100 in the pushing process is avoided.

In this embodiment, the elastic force unit 600 is mounted in the gap between the rear end of the detergent case 100 and the tank 200. The elastic sleeve 15 extends along the push-pull movement direction of the detergent case 100. Further, one end of the push lever sleeve 15 is fixedly connected to the rear end of the detergent case 100. The telescopic end of the push lever 16 extends from the other end of the push lever sleeve 15 and comes into contact with the inner wall of the tank 200 so that its position is regulated. The axial length of the push lever sleeve 15 is equal to or less than the distance between the detergent case 100 and the tank 200. When the spring 17 is in the free state, the sum of the push-out length of the expansion/contraction end of the push lever 16 and the axial length of the push lever sleeve 15 is the distance between the tank 200 and the rear wall of the detergent case 100.
