[0069] Fig.13 yes Fig.12 Schematic diagram of the structure from another perspective. Fig.14 yes Fig.13 Schematic diagram of the enlarged structure of area A in the middle.

[0070] See also Figures 5 to 14 As shown, in some embodiments, a first rack 313 and a second rack 314 are respectively provided on opposite side walls of the water inlet box 31, and the first rack 313 and the second rack 314 are arranged relatively parallel. At the same time, a first gear 33 and a second gear 34 are convexly provided on opposite side walls of the soap box drawer 32, and the first gear 33 and the second gear 34 are rotatably provided on the side walls of the soap box drawer 32. The first gear 33 is supported on the first rack 313, and the first gear 33 is meshed with the first rack 313. The second gear 34 is supported on the second rack 314, and the second gear 34 is meshed with the second rack 314.

[0071] When the soap box drawer 32 is pushed or pulled in the water inlet box 31, the first gear 33 can move along the first rack 313, and the second gear 34 can move synchronously on the second rack 314. When the first gear 33 moves on the first rack 313, the first gear 33 can maintain a meshing state with the first rack 313. Similarly, when the second gear 34 moves on the second rack 314, the second gear 34 can maintain a meshing state with the second rack 314. Therefore, when the soap box drawer 32 is pushed or pulled in the water inlet box 31, the first gear 33 and the second gear 34 can maintain synchronous movement on the first rack 313 and the second rack 314, respectively, to improve the synchronization of pushing and pulling the opposite sides of the soap box drawer 32, thereby effectively solving the problems of misalignment, poor synchronization, unsmoothness, easy jamming, etc. during the pushing and pulling process of the soap box drawer 32.

[0072] It should be noted that, by keeping the first gear 33 in meshing state with the first rack 313 and the second gear 34 in meshing state with the second rack 314, the positions of the two opposite sides of the soap box drawer 32 can be constrained, the two sides of the soap box drawer 32 can be kept relatively stable, and the stability of the push-pull position of the soap box drawer 32 can be improved. In this embodiment, by keeping the first gear 33 in meshing state with the first rack 313 and the second gear 34 in meshing state with the second rack 314, the push-pull speed of the soap box drawer 32 can also be effectively controlled, so that the soap box drawer 32 outputs a relatively stable linear push-pull speed, and the soap box drawer 32 is prevented from being damaged due to excessive push-pull speed.

[0073] It should also be noted that by keeping the first gear 33 and the first rack 313 in meshing state and the second gear 34 and the second rack 314 in meshing state, and cooperating with the limiting protrusion 324 and the limiting rib 3125 to limit the position, the soap box drawer 32 can be prevented from falling out of the water inlet box 31.

[0074] See also Figures 5 to 13As shown, in some embodiments, the first rack 313 and the second rack 314 are respectively arranged on the left and right side walls in the water inlet box 31, and the first rack 313 and the second rack 314 are both extended and arranged along the front-to-back direction of the water inlet box 31. At the same time, the first gear 33 and the second gear 34 are respectively arranged on the left and right outer side walls of the soap box drawer 32. Therefore, when the soap box drawer 32 is pushed or pulled at the first opening 3112 on the front side of the water inlet box 31, the soap box drawer 32 can move forward and backward in the water inlet box 31, the first gear 33 can roll along the length direction of the first rack 313, the second gear 34 can roll along the length direction of the second rack 314, and the first gear 33 and the second gear 34 can move forward and backward synchronously on the first rack 313 and the second rack 314 respectively.

[0075] It should be noted that, in other embodiments, when the first opening 3112 is provided on other side walls of the water inlet box 31 , the first rack 313 and the second rack 314 may also be provided on other opposite side walls of the water inlet box 31 , respectively.

[0076] In some embodiments, the first rack 313 and the second rack 314 are symmetrically disposed on the left and right side walls of the water inlet box 31. At the same time, the first gear 33 and the second gear 34 are symmetrically disposed on the left and right outer side walls of the soap box drawer 32. Therefore, by utilizing the left-right symmetrical structure of the first rack 313 and the second rack 314, the first gear 33 and the second gear 34, the stability of the push-pull position of the left and right sides of the soap box drawer 32 and the synchronization of push-pull can be further improved, and the problems of misalignment, poor synchronization, unsmoothness, easy jamming, etc. in the push-pull process of the soap box drawer 32 can be further solved.

[0093] See also Figure 7 and Fig.21As shown, in some embodiments, the first rack 313 is provided with a first suspended section 3130, and the second rack 314 is provided with a second suspended section 3140. When the soap box drawer 32 is pushed or pulled in the water inlet box 31, the first gear 33 and the second gear 34 can move synchronously on the first rack 313 and the second rack 314, respectively, and simultaneously enter the first suspended section 3130 and the second suspended section 3140, respectively, to be reset. If the first gear 33 and the second gear 34 are misaligned during the push-pull process of the soap box drawer 32, the first gear 33 and the second gear 34 can enter the first suspended section 3130 and the second suspended section 3140 respectively to reset, so that when the first gear 33 and the second gear 34 are respectively re-engaged with the first rack 313 and the second rack 314, they can maintain a synchronous movement state again, thereby realizing the reset function of the soap box drawer 32, improving the synchronization of pushing and pulling the left and right sides of the soap box drawer 32, and effectively solving the problem of easy misalignment and poor synchronization of the soap box drawer 32 during the push-pull process.

[0094] In addition, when installing the soap box drawer 32 into the water inlet box 31, there is no need to align the positions of the first gear 33 and the second gear 34 in advance. The soap box drawer 32 only needs to be installed and pushed into the water inlet box 31 to automatically update the positions of the first gear 33 and the second gear 34 to maintain a synchronous state, thereby ensuring that the first gear 33 and the second gear 34 are not misaligned, thereby effectively improving the installation efficiency of the production line.

[0095] In some embodiments, the first gear 33 and the second gear 34 are symmetrically disposed on the left and right outer walls of the soap box drawer 32. At the same time, the first rack 313 and the second rack 314 have the same length and are symmetrically disposed on the left and right side walls of the water inlet box 31. The first suspended section 3130 and the second suspended section 3140 have the same length and are arranged symmetrically. Therefore, when the first gear 33 and the second gear 34 move synchronously on the first rack 313 and the second rack 314, respectively, it can be ensured that the first gear 33 and the second gear 34 synchronously enter the first suspended section 3130 and the second suspended section 3140 for reset.

[0096] See also Figure 7 and Fig.21As shown, in some embodiments, the first suspended section 3130 is disposed at the rear end side of the first rack 313. The second suspended section 3140 is disposed at the rear end side of the second rack 314. Therefore, if the soap box drawer 32 is misaligned left and right when being pushed or pulled, as long as the soap box drawer 32 is completely pushed into the water inlet box 31, it can ensure that the first gear 33 and the second gear 34 enter the first suspended section 3130 and the second suspended section 3140 respectively, automatically update the position, refresh the state, and ensure that the left and right sides of the soap box drawer 32 are readjusted to a synchronized state. When the soap box drawer 32 is pulled out of the water inlet box 31 again, the first gear 33 and the second gear 34 can move synchronously on the first rack 313 and the second rack 314 respectively.

[0097] It should be noted that, in other embodiments, the first suspended section 3130 may also be disposed in the middle region or other position of the first rack 313, in which case the first suspended section 3130 divides the first rack 313 into two rack sections arranged at intervals. Similarly, the second suspended section 3140 may also be disposed in the middle region or other position of the second rack 314, in which case the second suspended section 3140 divides the second rack 314 into two rack sections arranged at intervals.

[0098] In some embodiments, a plurality of first suspended sections 3130 may also be provided on the first rack 313, and the plurality of first suspended sections 3130 are arranged at intervals along the length direction of the first rack 313. Similarly, a plurality of second suspended sections 3140 may also be provided on the second rack 314, and the plurality of second suspended sections 3140 are arranged at intervals along the length direction of the second rack 314. At the same time, the plurality of first suspended sections 3130 and the plurality of second suspended sections 3140 are arranged in a one-to-one correspondence. Therefore, the first gear 33 and the second gear 34 can be reset at any set of the first suspended sections 3130 and the corresponding second suspended sections 3140.

[0099] See also Figure 6 and Fig.21 As shown, in some embodiments, a support rib 327 is protruded on the left and right outer walls of the soap box drawer 32, and the support rib 327 is arranged to extend in the front-to-back direction. At the same time, a support platform 3114 is formed on the left and right inner walls of the box body 311, and the extension direction of the support platform 3114 is consistent with the extension direction of the rack, that is, the support platform 3114 is arranged to extend in the front-to-back direction. When the first gear 33 and the second gear 34 enter the first suspended section 3130 and the second suspended section 3140 respectively for reset, the support ribs 327 on the left and right sides can be supported on the support platforms 3114 on the left and right sides respectively, so that the first gear 33 and the second gear 34 are arranged in the air, thereby realizing the reset function of the first gear 33 and the second gear 34.

The soap box drawer 32 is arranged in the water inlet box 31 in a push-pull manner, so that detergent is conveniently added into the soap box drawer 32 and then into the washing chamber 20 of the washing tub 2. The first gear 33 and the second gear 34 on the left and right outer walls of the soap box drawer 32 are engaged and moved in coordination with the first rack 313 and the second rack 314 on the left and right side walls of the water inlet box 31, so that when the soap box drawer 32 is pushed and pulled in the water inlet box 31, the first gear 33 and the second gear 34 can move synchronously on the first rack 313 and the second rack 314 respectively, and simultaneously If the first gear 33 and the second gear 34 are misaligned during the pushing and pulling process of the soap box drawer 32, the first gear 33 and the second gear 34 can respectively enter the first suspended section 3130 and the second suspended section 3140 for reset, so that when the first gear 33 and the second gear 34 are respectively re-engaged with the first rack 313 and the second rack 314, they can maintain a state of synchronous movement again, thereby realizing the reset function of the soap box drawer 32, improving the synchronization of pushing and pulling the left and right sides of the soap box drawer 32, and effectively solving the problem of easy misalignment and poor synchronization of the soap box drawer 32 during the pushing and pulling process.

[0102] In addition, when installing the soap box drawer 32 into the water inlet box 31, there is no need to align the positions of the first gear 33 and the second gear 34 in advance. The soap box drawer 32 only needs to be installed and pushed into the water inlet box 31 to automatically update the positions of the first gear 33 and the second gear 34 to maintain a synchronous state, thereby ensuring that the first gear 33 and the second gear 34 are not misaligned, thereby effectively improving the installation efficiency of the production line.
