Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a drying mechanism of a washing machine used for washing tableware, fruits and vegetables. Background Art

[0002] As people's living standards continue to improve, dishwashers, as a kitchen appliance, are entering more and more households.

[0003] At present, the structure of the relatively mature water tank type cleaning machine on the market is mainly as described in the Chinese patent "Water Tank Type Cleaning Machine" (application number: CN201310750968.1) with the authorization announcement number CN104224074B, that is, it includes a box body forming a washing space, the box body includes a water tank body and a cover plate rotatably connected to the water tank body, the bottom of the water tank body has a concave drain area at least in the central part, and the drain area is provided with a water pump that pumps the water in the drain area out to the washing space above the drain area, the drain area is covered with a drain plate with drain holes, and a rotating spray arm connected to the water pump fluid and having a water outlet hole is arranged above the drain plate. By setting a drain area covered with a drain plate and setting the water pump in the drain area, the water pump is isolated from the washing area, so that the water flowing back into the water pump is first filtered by the drain plate.

[0004] The structure for drying dishes in the above-mentioned dishwasher mainly utilizes a fan to blow air directly into the tank and then blow it out, relying on the wind speed to achieve convection diffusion under natural conditions, which results in uneven distribution of airflow in the tank and poor drying effect.

The blowing assembly 2 is provided with a blowing hole 211 arranged toward the washing chamber. The driving assembly 3 is arranged outside the housing 1, and the output end passes through the portion of the housing 1 corresponding to the bottom of the receiving groove 120 and is connected to the bottom of the blowing assembly 2, so as to drive the blowing assembly 2 to move up and down. An air outlet 123 is provided on the second side wall 122 of the housing 1, and the air blown into the washing chamber by the blowing assembly 2 can be discharged through the air outlet 123 after convection. The interior of the blowing assembly 2 is hollow to form an air collecting chamber 124 connected to the blowing hole 123, and the bottom of the air collecting chamber 124 can be connected to the air supply mechanism.

[0028] The blowing assembly 2 of this embodiment includes an air collecting box 21, which is a flat rectangular parallelepiped. When the air collecting box 21 is located in the accommodating groove 120, the outer wall of the air collecting box 21 is kept flush with the corresponding inner wall of the box body 1, and the blowing hole 211 is opened on the outer wall of the air collecting box 21. With the above structure, the whole inside of the washing chamber remains unchanged, the washing space is not affected, and the air collecting box can be protected.

[0029] The outer wall of the air collecting box 21 is provided with a baffle 23 which can be flipped downward to cover the air blowing hole 211 and flipped upward to expose the air blowing hole 211. The upper edge of the baffle 23 is rotatably connected (hinged) to the upper edge of the outer wall of the air collecting box 21. The inner wall of the baffle 23 forms an air guide surface which can restrict the air blowing direction of the air blowing hole 211 according to the setting of the flip angle thereof. The baffle can be used to set the air blowing direction as needed, thereby improving the efficiency and effect of drying the dishes.

[0030] The driving assembly 3 includes a push rod motor 31, which is arranged outside the box 1 and below the receiving groove 120. The push rod 32 of the push rod motor 31 passes through the box 1 corresponding to the bottom of the receiving groove 120 and is connected to the bottom of the air collecting box 21, so as to provide support force and driving force for the air collecting box 21 to move up and down. The push rod 32 is arranged at the central part of the bottom of the air collecting box 21 so that the air collecting box 21 can move up and down relatively smoothly. The above structure is adopted to realize the driving of the air collecting box 21 to reciprocate up and down.

[0031] The push rod 32 of the push rod motor 31 is hollow inside, and a telescopic motor 33 is arranged in the hollow push rod 32, which can move up and down with the push rod 32 and can move up and down relative to the push rod 32. The output shaft of the telescopic motor 33 is connected to the baffle 23 through a transmission assembly 34 to drive the baffle 23 to flip. The above structure is integrated with the driving structure of the air collecting box 21, which can greatly simplify the assembly space and facilitate the drive to flip the baffle.

[0032] The transmission assembly 34 includes a first guide wheel 341, a second guide wheel 342 and a pull rope 343. The first guide wheel 341 is rotatably disposed on the inner top wall of the air collecting box 21 and arranged corresponding to the upper end of the output shaft of the telescopic motor 33. The second guide wheel 342 is rotatably disposed on the inner top wall of the air collecting box 21 and is located in front of the first guide wheel 341. The height of the second guide wheel 342 is lower than the first guide wheel 341 and the upper edge of the baffle 23. The first end of the pull rope 343 is connected to the upper end of the output shaft of the telescopic motor 33. The pull rope 343 bypasses the first guide wheel 341 and the second guide wheel 342 from bottom to top and is connected to the upper edge of the baffle 23. The above structure is adopted to achieve stable driving of the baffle 23 to flip.

[0033] The bottom of the air collecting box 21 is provided with an air inlet 212 arranged near the first end thereof, and a telescopic tube 213 is connected below the air inlet 212, and the lower end of the telescopic tube 213 passes through the bottom of the receiving groove 120 and is connected to the air supply mechanism outside the box body 1. With the above structure, it is convenient to supply air to the air collecting box 21 without affecting the up and down movement of the air collecting box 21. The bottom of the air collecting box 21 is provided with a drainage hole 217 for draining the accumulated water therein, so as to keep the air collecting box 21 dry and free of residual water.
