Referring to FIG. 1 to FIG. 19 together, the damper assembly 10 of the embodiment of the present invention includes a body 12, an air damper 14 disposed on the body 12, a spring 16 and a slider 18.

The body 12 is formed with a chute 121. The air damper 14 includes a cylinder 141 disposed on the body 12 and a piston rod 142 coupled to the cylinder 141. The spring 16 is fixedly coupled to the body 12. The slider 18 is coupled to the free end 1421 of the piston rod 142 and the free end 161 of the spring 16. The slider 18 is slidably disposed in the chute 121. The slider 18 is configured to guide the pull-down spring 16 and the piston rod 142 from the initial position A (shown in FIG. 4) to the locked position B locked in the chute 121 by the first external force. 7)). The slider 18 is also used to unlock from the chute 121 under the action of the second external force, return to the initial position A under the restoring force of the spring 16, and slowly rest in the initial position by the cushioning force of the air damper 14 when approaching the initial position A. A.

The damper assembly 10 of the embodiment of the present invention can be applied to the rail assembly 20 (shown in FIG. 10) of the embodiment of the present invention. The rail assembly 20 of the embodiment of the present invention includes a carrier rail 21 and a sliding portion disposed in the carrier rail 21. A guide rail 22, a damper assembly 10 according to any of the embodiments of the present invention, and a block 23 fixed to the first guide rail 22. The body 12 is fixed to the carrier rail 21. The block 23 is for engaging with the slider 18 to apply a first external force and a second external force to the slider 18.

The rail assembly 20 of the embodiment of the present invention can be applied to the dishwasher 100 of the embodiment of the present invention (as shown in FIGS. 18 and 19). The dishwasher 100 of the embodiment of the present invention includes a liner 30, a bowl 40 that is at least partially received in the liner 30, and a rail assembly 20 according to any of the embodiments of the present invention. The carrier rail 21 is secured to the liner 30 and the first rail 22 is secured to the bowl 40 to allow the bowl 40 to be withdrawn and pushed into the liner 30.

Thus, since the slider 18 of the damper assembly 10 can automatically return under the restoring force of the spring 16, and can be slowly stopped in the initial position A under the cushioning force of the air damper 14, that is, the flexible contact groove 121, The damper assembly 10 is provided with an automatic pull-in function and can cushion the force, such that when the bowl basket 40 is pushed and pulled by the rail assembly 20 including the damper assembly 10, the bowl 40 can be restored at the spring 16 of the damper assembly 10. The force can be automatically pulled into the liner 30 of the dishwasher 100, which facilitates the advancement of the bowl 40, and the air damper 14 of the damper assembly 10 ensures that the bowl can be pushed into the bowl 40 The basket 40 slowly rests on other parts of the dishwasher (such as water pipes), which reduces the noise of the basket 40 colliding with other components, improving the user experience while damping The spring 16 of the device 10 can slow the speed at which the bowl basket 40 is pulled out to prevent the bowl basket 40 from slipping out of the liner 30 too quickly under its own weight to cause the tableware to slip and damage.

In the embodiment of the present invention, the body 12 has a substantially rectangular parallelepiped shape, and the air damper 14 and the spring 16 are disposed along the longitudinal direction of the body 12.

In the example of the present invention, the sliding process of the slider 18 can be seen in FIGS. 4-7. Specifically, the piston rod 142 includes a piston 143 (see FIG. 9), and a gap is formed between the piston 143 and the inner wall of the cylinder block 141. The spring 16 is a tension spring. When the external force acting on the slider 18 is the first external force, the piston 143 moves to the right side from the initial position A with the piston rod 142 (as shown in FIGS. 4 and 5), and the air volume on the right side of the piston 143 at this time. Shrinking, and the pressure is increased, so that the air located on the right side of the piston 143 flows from the gap between the piston 143 and the inner wall of the cylinder 141 to the left side of the piston 143, so that a buffering force opposite to the first external force can be formed, thereby slowing down The speed of movement of the piston 143 and the slider 18 ensures that the piston rod 142 moves at a relatively slow speed. At the same time, under the action of the first external force, the spring 16 is pulled and elongated, so that the moving speed of the slider 18 can also be slowed down. When the slider 18 is slid to the locked position B, the spring 16 is in a stretched state (as shown in Fig. 7). Thus, under the dual action of the air damper 14 and the spring 16, the slider 18 slides along the chute 121 at a relatively slow speed.

Similarly, when the external force acting on the slider 18 is the second external force, the slider 18 is unlocked from the chute 121 and moves along the chute 121 to the left side of the body 12 under the restoring force of the spring 16. At this time, the slider 18 drives the piston 143 to move to the left side with the piston rod 142 from the locking position B. At this time, the volume of the air on the left side of the piston 143 is reduced, and the pressure is increased, so that the air located on the left side of the piston 143 is from the piston 143. The gap with the inner wall of the cylinder 141 flows to the right side of the piston 143, thereby forming a cushioning force that slows down the speed at which the slider 18 slides to the left side, thereby ensuring that the slider 18 is slowly stopped at the initial position A.

It should be noted that "left side" and "right side" are positional states in the normal use state of the damper assembly 10, for example, the positional state of the damper assembly 10 shown in FIG.

In one embodiment, the body 12 includes a base 122 and an upper cover 123 fixedly disposed on the base 122. The air damper 14, the spring 16, and the slider 18 are disposed between the base 122 and the upper cover 123.

Thus, the base 122 and the upper cover 123 have the functions of supporting and protecting the air damper 14, the spring 16 and the slider 18, thereby ensuring the stability of the damper assembly 10 when in use.

Specifically, in the embodiment of the present invention, the upper cover 123 is provided with a notch 124, and a portion of the slider 18 is exposed to the notch 124. Thus, by applying an external force to the slider 18, the first external force and the second external force can be directly applied to the portion of the slider 18 exposed to the notch 124.

In one embodiment, the base 122 is rectangular and includes a base rear end 125 and a base front end 126 on either side of the length of the base 122. The chute 121 is disposed adjacent to the front end 126 of the base and extends substantially along the length of the base 122. The base 122 is formed with a damper mounting groove 1221 for mounting the air damper 14 and a mounting spring 16 The spring mounts the slot 1222. The damper mounting groove 1221 and the spring mounting groove 1222 are disposed near the rear end 125 of the base and extend along the length direction of the base 122. The cylinder 141 is disposed adjacent to the rear end 125 of the base. The spring 16 includes a fixed end 162 opposite the free end 161 of the spring 16. The fixed end 162 is adjacent to the base rear end 125.

As such, the structure of the damper assembly 10 is relatively compact, and the manner in which the chute 121 and the air damper 14 and the spring 16 are staggered back and forth allows the slider 18 to have a sufficient sliding space to ensure the use of the damper assembly 10 while The mounting groove has the function of protecting and limiting the air damper 14 and the spring 16, and can ensure that the position of the air damper 14 and the spring 16 is relatively stable when used.

In the embodiment of the present invention, the chute 121 is located between the damper mounting groove 1221 and the spring mounting groove 1222. Thus, the slider 18 can slide along the chute 121 more smoothly. The spring mounting groove 1222 is formed with a card slot 1223 that fixes the fixed end 161 to stabilize the fixed end 162 of the spring 16.

In one embodiment, the free end 1421 of the piston rod 142 and the free end 161 of the spring 16 are rotatably coupled to the slider 18. The chute 121 includes a straight chute 1211 and a folding chute 1212. The straight chute 1211 extends along the length direction of the base 122. The folding chute 1212 includes a straight sliding groove section 1213 extending along the longitudinal direction of the base 122 and located on one side of the straight sliding groove 1211 and a folding groove section 1214 which is deflected from the straight sliding groove section 1213 away from the longitudinal direction of the base 122. The slider 18 includes a sliding piece 181, a first sliding shaft 182 extending outward from the sliding piece 181 and slidingly disposed in the straight sliding groove 1211, and a second sliding shaft 183 slidingly disposed in the folding groove 1212. The slider 18 is configured to slide under cooperation of the first sliding shaft 182 with the straight sliding slot 1211 and the second sliding shaft 183 and the straight sliding slot segment 1213 under the action of the first external force, and is straight-slided on the first sliding shaft 182. The slot 1211 is blocked and the second sliding shaft 183 is slid into the folding slot section 1214 and locked in the locking position B of the sliding slot 121.

In this way, the parallel arrangement of the straight sliding slot 1211 and the folding chute 1212 can ensure the smoothness of sliding of the slider 18. At the same time, the manner in which the sliding shaft cooperates with the sliding slot makes it difficult for the slider 18 to slide off the sliding slot 121 when moving, further When the slider 18 is slid to the locked position B, the second sliding shaft 183 is slid into the folding slot section 1214 to achieve locking of the slider 18 in a relatively simple manner.

In an embodiment of the invention, the slider 18 is substantially T-shaped. When the first sliding shaft 182 is stopped by the straight chute 1211, the slider 18 is forced to rotate downward so that the second sliding shaft 183 slides into the folding chute section 1214.

In the example of the present invention, the distance between the first sliding shaft 182 and the second sliding shaft 183 is greater than the distance between the rightmost end of the straight chute 1211 and the leftmost end of the folding chute section 1214. This ensures that the second sliding shaft 183 slides sufficiently into the folding groove section 1214 to ensure the locking effect on the slider 18. It can be set according to the actual application.

It should be noted that the "rightmost end" and "leftmost end" are the positional states of the damper assembly 10 in the normal use state, for example, the positional state of the damper assembly 10 shown in FIG.

In one embodiment, the sliding sheet 181 is formed with a rolling groove 184. The free end 1421 of the piston rod 142 is formed with a roller 1422 that is rolled and disposed in the rolling groove 121.

Thus, the rotational fit of the roller 1422 and the rolling groove 184 is relatively simple, easy to implement, and has good rotational stability.

In one embodiment, the upper cover 123 is formed with an auxiliary straight chute 1231 that cooperates with the straight chute 1211 and an auxiliary chute groove 1232 that cooperates with the folding chute 1212. The first sliding shaft 182 is slidably disposed in the auxiliary straight chute 1231. The second sliding shaft 183 is slidably disposed in the auxiliary folding groove 1232.

As such, the sliding balance of the slider 18 is better, and the piston rod 142 and the spring 16 are less likely to be displaced during the movement, thereby improving the accuracy of the damper assembly 10 when in use.

In one embodiment, the slider 18 is formed with a mating slot 185 that mates with the latch 23. The block 23 can be snapped into or out of the mating slot 185. The block 23 is used to snap into the fitting groove 185 to apply a first external force and a second external force to the slider 18.

Thus, the engagement of the block 23 with the engaging groove 185 allows the first external force and the second external force to be stably and continuously applied to the slider 18 to ensure the stability of the sliding of the slider 18.

Specifically, in the embodiment of the present invention, the damper assembly 10 is located on one side of the carrying rail 21, and when the first rail 22 slides relative to the side of the carrying rail 21 away from the damper assembly 10, the first rail 22 can be The slider 23 is engaged with the engaging groove 185 to drive the slider 18 to guide the pull-down spring 16 and the piston rod 142 to slide from the initial position A to the locking position B locked to the sliding groove 121 at the sliding groove 121. When the slider 18 is in the locked position B, the block 23 is disengaged from the mating groove 185 (as shown in FIG. 15), so that the first guide rail 22 can continue to slide relative to the carrier rail 21 after the position of the slider 18 is fixed.

When the first rail 22 slides toward the side of the damper assembly 10 with respect to the carrier rail 21, the first rail 22 can be re-engaged into the mating slot 185 by the latch 23 to unlock the slider 18 from the chute 121, thereby The slider 18 returns to the initial position A under the restoring force of the spring 16.

In one embodiment, the rail assembly 20 includes a connector 24. The connector 24 is used to connect the first rail 22 with an external component. The connector 24 includes a connector body 241. The connector body 241 is formed with a mating end 242 that mates with the block 23.

As such, the rail assembly 20 can be coupled to external components, such as the bowl 40 in the example of the present invention, through the connector 24, which ensures stability of the rail assembly 20 to the external components. At the same time, the card block 23 is disposed on the connector body 241 such that the force receiving point of the first rail 22 is concentrated on the connecting member 24, thereby protecting the first rail 22 to a certain extent, and simultaneously clamping the block. 23 cooperates with the mating end 242 to make the structure compact.

In the example of the invention, the connector 24 is a platinum connector. This is more stable to use. The block 23 is detachably coupled to the mating end 242. This facilitates the attachment of the rail assembly 20 to an external component, such as a bowl basket.

In one embodiment, the rail assembly 20 includes a second rail 25, a first ball (not shown), and a second ball (not shown). The second rail 25 is slidably disposed within the carrier rail 21 by a second ball. The first rail 22 is slidably disposed within the second rail 25 by a first ball.

Thus, the second guide rail 25 is disposed between the first guide rail 22 and the carrier rail 21, so that the sliding stroke of the rail assembly 20 can be increased, and at the same time, the arrangement of the balls can reduce the frictional force of sliding between the guide rails.

In the embodiment of the present invention, the number of the first balls is plural, and the number of the second balls is plural. A plurality of first balls are spaced apart between the first rail 22 and the second rail 25, and a plurality of second balls are spaced apart between the second rail 25 and the carrier rail 21.

In one embodiment, the damper assembly 10 is disposed adjacent the inner side of the inner liner 30 with respect to the carrier rail 21.

As such, the damper assembly 10 can effectively buffer noise when the bowl 40 collides with other portions of the dishwasher, such as water pipes.

Specifically, in the embodiment of the present invention, the body 12 is fixed to the inner wall 31 of the inner liner 30 together with the carrier rail 21, and the body 12 is located outside the carrier rail 21. The first rail 22 is fixedly coupled to the bowl 40 by a connector 24.

When the bowl 40 is pulled out of the inner casing 30, the bowl 40 drives the first rail 22 to slide toward the outside of the inner casing 30 with respect to the carrying rail 21, at which time the block 23 snaps into the engaging groove 185 and drives the slider 18 in the chute. The guide pull-down spring 16 and the piston rod 142 are slid from the initial position A to the locked position B locked to the chute 121. During this process, due to the buffering action of the spring 16 and the air damper 14, it is ensured that the bowl 40 does not slide out of the liner 30 too quickly under the action of its own gravity, causing the tableware to slip and damage.

When the slider 18 is in the locked position B, both the spring 16 and the piston rod 142 are in a stretched state. When the slider 18 is in the locking position B, the block 23 is disengaged from the engaging groove 185, so that after the position of the slider 18 is fixed, the first guide rail 22 can continue to slide relative to the carrier rail 21 to cause the bowl basket 40 to be pulled out of the liner. 30.
