Description

Technical Field

[0001] The utility model relates to a water washing device for reducing down damage. Background Art

[0002] Chinese patent application number 202222974530.9 discloses a water washing device (specifically a down cleaning device) for reducing down damage. The device can clean and air-dry the down, so that the down can be restored to a flocculent state after cleaning, thereby reducing down damage.

[0003] The water washing device of this patent (specifically a down washing device) includes: a washing cylinder, a top plate arranged at the top of the washing cylinder, a lifting mechanism for driving the top plate to rise and fall (the lifting mechanism includes a limit rod, a threaded rod, a slider, a support rod, a first motor, etc.), a first air pump externally connected to the top surface of the top plate, a water inlet pipe externally connected to the top surface of the top plate and with an opening and closing valve, a fan arranged on the bottom surface of the top plate, a stirring mechanism arranged inside the washing cylinder (the stirring mechanism includes a stirring paddle, a rotating shaft, a transmission belt, a second motor, etc.), a feed pipe externally connected to the right end of the washing cylinder, a discharge pipe externally connected to the left end of the washing cylinder, a second air pump arranged at the left end of the washing cylinder and connected to the discharge pipe, a filter screen arranged at the bottom of the washing cylinder, and a water outlet pipe externally connected to the bottom of the washing cylinder and with a valve.

[0004] The working principle of this patented water washing device (specifically a down cleaning device) includes: by turning on the first air pump, the down is drawn into the cleaning drum along the feed pipe; then, cleaning liquid is injected into the cleaning drum through the water inlet pipe, and the down in the cleaning drum is stirred and cleaned by a stirring mechanism (stirring paddle); after the cleaning is completed, the cleaning liquid is discharged from the water outlet pipe, and the down is retained on the filter net; then, the down in the cleaning drum is air-dried by a fan, so that the cleaned down returns to a flocculent state; then, by turning on the second air pump, the down in the cleaning drum is drawn out along the discharge pipe.

[0005] Although the water washing device of this patent (specifically a down cleaning device) can dry the down in the cleaning drum through a fan after cleaning is completed, so that the cleaned down returns to its flocculent state; but the fan is arranged on the bottom surface of the top plate, that is, the fan is arranged inside the cleaning drum; therefore, when the stirring mechanism (stirring paddle) stirs and cleans the down in the cleaning drum, cleaning liquid may splash onto the fan, thereby causing adverse effects due to water entering the fan; and when the fan dries the down in the cleaning drum, some down may be blown into the fan, thereby causing adverse effects due to the fan being stuck in the down; in addition, the down entering the fan may be damaged by the fan blades, and the down damaged by the fan blades may subsequently fall to the bottom of the cleaning drum, and eventually be mixed with good products (undamaged down) and be drawn out.

[0021] The fan 5 is arranged above the top plate 2, and the bottom end of the fan 5 is connected to the interior of the washing drum 1 through a ventilation pipe 20 externally connected to the top surface of the top plate 2; the top plate 2 is provided with a vertical through hole 21 for connecting the ventilation pipe 20 with the interior of the washing drum 1, and the bottom end of the through hole 21 is closed by a blocking net 22 for blocking down; a gate valve 23 is also connected in series to the ventilation pipe 20, and the gate valve 23 is close to the top plate 2. The top surface of the top plate 2 is also provided with a driving cylinder for driving the valve plate 24 of the gate valve 23 to open and close; an electric heating pipe 25 is also provided inside the ventilation pipe 20, and the electric heating pipe 25 is located between the gate valve 23 and the fan 5;

[0022] There are two ventilation pipes 20 (the two ventilation pipes 20 are respectively equipped with a fan 5, an electric heating pipe 25, and a gate valve 23), and the valve plates 24 of the gate valves 23 on the two ventilation pipes 20 are driven to open and close by the same driving cylinder; the driving cylinder is a double-headed cylinder 26, and the two ventilation pipes 20 are respectively arranged on both sides of the double-headed cylinder 26, and the valve plates 24 of the gate valves 23 on the two ventilation pipes 20 are respectively connected to the piston rods 27 on both sides of the double-headed cylinder 26;

[0023] The two ventilation pipes 20 are symmetrically arranged; the fans 5 on the two ventilation pipes 20 are symmetrically arranged; the electric heating pipes 25 on the two ventilation pipes 20 are symmetrically arranged; and the gate valves 23 on the two ventilation pipes 20 are symmetrically arranged.

[0024] The working principle of the water washing device (specifically a down washing device) of the utility model includes:

[0025] The double-headed cylinder 26 drives the two gate valves 23 on the ventilation pipes 20 to close; then the first air pump 3 is turned on to draw the down along the feed pipe 19 into the cleaning drum 1;

[0026] Then, cleaning liquid is injected into the cleaning drum 1 through the water inlet pipe 4, and the down in the cleaning drum 1 is stirred and cleaned by the stirring mechanism (stirring paddle); during the cleaning process, the valve plate 24 of the gate valve 23 can block the splashing cleaning liquid, preventing the cleaning liquid from splashing onto the fan 5, thereby avoiding adverse effects caused by water entering the fan 5;

[0027] After the cleaning is completed, the cleaning liquid is discharged from the water outlet pipe, and the down is retained on the filter screen; after the cleaning liquid is discharged, the double-headed cylinder 26 drives the two gate valves 23 on the ventilation pipes 20 to open; then the fan 5 is used to air-dry the down in the cleaning cylinder 1, so that the cleaned down is restored to a flocculent state; during the air-drying process, the electric heating pipe 25 in the ventilation pipe 20 can be turned on to heat the air introduced by the fan 5, thereby accelerating the drying of the down; and during the air-drying process, the blocking net 22 at the bottom of the through hole 21 of the top plate 2 can block the down from entering the ventilation pipe 20, preventing the down from being blown into the fan 5, thereby avoiding adverse effects caused by the fan 5 getting stuck in the down;

[0028] After air drying is completed, the double-headed cylinder 26 drives the gate valves 23 on the two ventilation pipes 20 to close; then the second air pump is turned on to draw the down in the cleaning drum 1 along the discharge pipe 11; due to the blocking net 22, the down will not be damaged by the blades of the fan 5, so no down damaged by the blades of the fan 5 will be mixed with the good down (undamaged down) and be drawn out.

[0029] As can be seen from the above, the water washing device (specifically, the down washing device) of the present invention can wash and air-dry the down, so that the washed down can be restored to a flocculent state, thereby reducing damage to the down; it can also prevent the washing liquid from splashing onto the fan 5 during the washing process, thereby avoiding adverse effects caused by water entering the fan 5; it can also prevent the down from being blown into the fan 5 during the air-drying process, thereby avoiding adverse effects caused by the fan 5 being stuck in the down; it can also ensure that the down will not be damaged by the blades of the fan 5, thereby ensuring that the down damaged by the blades of the fan 5 will not be mixed into good products (undamaged down) and be extracted.

[0030] This utility model partially improves the down damage reduction water washing device disclosed in Chinese Patent Application No. 202222974530.9.
