[0034] like Figures 1-5As shown, this utility model provides a water receiving tray assembly 10, including a water receiving tray 100, a driving member 200, a transmission member 300, and a screw 400. The water receiving tray 100 is provided with a drain hole 110. The driving member 200 is disposed on the water receiving tray 100 and located on one side of the drain hole 110. The transmission member 300 is disposed on the top of the drain hole 110 and directly opposite the drain hole 110. The transmission member 300 is connected to the driving member 200 and can rotate along a first direction and a second direction under the drive of the driving member 200. The screw 400 passes through the transmission member 300 and is threadedly connected to the transmission member 300. The screw 400 is positioned directly opposite the drain hole 110 so that when the transmission member 300 rotates along the first direction, it drives the screw 400 to rotate and extend into the drain hole 110, and when it rotates along the second direction, it drives the screw 400 to rotate and move out of the drain hole 110.

[0035] It should be noted that the first direction and the second direction are opposite directions of rotation. The transmission component 300 can switch between rotating in the first direction and rotating in the second direction according to the driving rotation direction of the driving component 200. The transmission component 300 rotates around its central axis in both the first direction and the second direction.

[0036] The transmission component 300 is fixed on the water receiving tray 100. Since the transmission component 300 is threadedly connected to the screw 400, as the transmission component 300 rotates, the screw 400 rotates and moves upward or downward accordingly. When the screw 400 moves downward, it gradually extends into the drain hole 110, and when the screw 400 moves upward, it gradually moves away from or out of the drain hole 110.

[0037] Generally, when the driving member 200 drives the transmission member 300 to rotate in the first direction, the screw 400 rotates and moves downwards to extend into the drain hole 110. When the driving member 200 drives the transmission member 300 to rotate in the second direction, the screw 400 rotates and moves upwards to move out of the drain hole 110.

[0038] It is understood that the water tray assembly 10 is provided with a driving component 200 and a transmission component 300 on the water tray 100. The driving component 200 drives the transmission component 300 to rotate in a first direction and a second direction, so that the screw 400 passes through the transmission component 300 and is threadedly connected, so that the screw 400 is directly connected to the drain hole 110 of the water tray 100. The driving component 200 drives the transmission component 300 to rotate in the first direction, so that the screw 400 rotates and extends into the drain hole 110. The driving component 200 drives the transmission component 300 to rotate in the second direction, so that the screw 400 rotates and moves out of the drain hole 110. This utility model completes the unblocking and cleaning of dirt in the drain hole 110 by driving the screw 400 to extend and move out.

[0039] In some embodiments, the drive member 200 includes a motor 201 and a drive gear 202 connected to the motor 201. The transmission member 300 is a transmission gear that meshes with the drive gear 202, and a screw 400 passes through the transmission gear and is threadedly connected to the transmission gear.

[0040] The drive gear 202 is connected to the motor shaft of the motor 201. The motor 201 drives the drive gear 202 to rotate, and the drive gear 202 drives the transmission gear to rotate. By controlling the rotation direction of the motor shaft of the motor 201, the transmission gear can rotate in a first direction or a second direction.

[0041] In some embodiments, the transmission gear includes a cylinder 310 and an external tooth 320, the external tooth 320 being disposed around the cylinder 310, the cylinder 310 having a threaded hole 301 penetrating the cylinder 310, and the cylinder 310 being threadedly connected to the screw 400 through the threaded hole 301.

[0042] The outer toothed portion 320 is a toothed structure surrounding the periphery of the cylinder 310. The toothed structure can be integrally formed with the cylinder 310 or detachably connected to the cylinder 310.

[0043] The threaded hole 301 is provided through the cylinder 310 along the height direction of the cylinder 310, and the screw 400 passes through the threaded hole 301 in the cylinder 310.

[0044] In some embodiments, the water tray assembly 10 further includes a mounting box 600, which is detachably mounted on the water tray 100. The drive gear 202, the transmission gear, and the screw 400 are all mounted in the mounting box 600. The motor 201 is mounted on the top of the mounting box 600, and the motor shaft of the motor 201 passes through the top of the mounting box 600 and is connected to the drive gear 202. The top of the mounting box 600 is provided with a first screw through hole, and the bottom of the mounting box 600 is provided with a second screw through hole. The first screw through hole and the second screw through hole are arranged opposite each other, and the screw 400 passes through the first screw through hole and the second screw through hole.
