Description

Technical Field

[0001] The present invention belongs to the technical field of sweater air-drying, and in particular relates to a sweater air-dryer. Background Art

[0002] At present, in order to meet the warmth retention needs in winter, most people choose cashmere and wool clothes to meet their own warmth retention needs. However, the cleaning of cashmere and wool clothes has become a problem. Currently, most of the dehydration technologies for daily use are household dehydrators. Such household dehydrators mainly use centrifugal dehydration, relying on the centrifugal force generated by the high-speed rotation of the laundry tub to throw out the water in the clothes. Although such household dehydrators can meet the dehydration needs of ordinary clothes in daily life, they cannot meet the dehydration needs of cashmere and wool clothes. Most of the current drying technologies use hot air to heat and dry the clothes. The household dryers used in daily life adopt the form of hot air drying to dry the clothes. However, this method is not suitable for cashmere and wool clothes. The labels on cashmere and wool clothes also clearly indicate that the clothes cannot be dehydrated and dried by common centrifugal dehydration, hot air drying, etc. However, since there is no device in daily life that can correctly dehydrate and dry cashmere and wool clothes, most people use centrifugal dehydrators to dehydrate cashmere and wool clothes. This will cause deformation problems such as elongation and widening of the materials of cashmere and wool clothes, resulting in pilling on the surface of cashmere and wool clothes, leading to damage to cashmere and wool clothes. Moreover, during the drying process after the dehydration of cashmere and wool clothes, if a hot air dryer is used, it will damage the protein fibers in the cashmere and wool clothes, causing the cashmere and wool clothes to show phenomena such as fiber softening and wrinkling deformation, affecting the beauty and comfort of people when wearing sweaters. Currently, household dehydrators and dryers cannot solve these problems. The present invention intends to use a row of nozzles to solve this problem. When the air flow passes through the nozzle, the dynamic pressure decreases and the temperature decreases. The air flow passing through the nozzle becomes a low-temperature and low-pressure air flow, which cools and dehumidifies the water in the sweater and quickly air-dries it. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that sweaters are easily deformed during hot air drying, and to provide a sweater air-dryer. Based on the idea of bionics, the sweater air-dryer lays the sweater flat on the mesh surface and imitates the way of squeezing water by hand to squeeze out the water in the wet sweater, avoiding the deformation problem of the sweater caused by using a centrifugal dehydrator. By using a piston rod, a cylinder and a row of nozzles, through mechanical movement, the air flow passing through the wet sweater becomes a low-temperature and low-pressure air flow. It can not only ensure air-drying with cold air, but also avoid the problem of sweater fiber softening caused by too high temperature during the air-drying process of the sweater.

[0004] The present invention is implemented by the following technical solutions: A sweater air dryer, characterized in that: it mainly includes an air dryer main body in the upper part and a drainage system in the lower part. The air dryer main body is composed of a cylinder, a piston, a row of spray nozzles, a one-way valve, small grooves, large holes, large grooves, an upper screen, large T-shaped pins and a piston rod. The drainage system is composed of a drainage funnel, a lower screen, a drainage filter screen, small holes, small T-shaped pins and a drainage port. The row of spray nozzles is evenly distributed below the cylinder. Small grooves are arranged on the left and right outer sides of the row of spray nozzles. An upper screen is arranged below the row of spray nozzles. Large T-shaped pins are arranged on the left and right sides of the cylinder respectively. The cylinder and the piston rod can be fixed through the large T-shaped pins. The small T-shaped pins on both sides of the drainage funnel can pass through the small holes on the left and right sides and be fixed to the small grooves. The lower screen, the drainage filter screen and the drainage port are arranged in sequence from top to bottom above the drainage funnel. When squeezing the water in the sweater, the large T-shaped pin fixes the piston rod through the large hole, making the piston rod and the cylinder form an integral body. The piston rod moves up and down, thereby driving the cylinder to continuously squeeze out the water in the sweater. The water in the sweater passes through the lower screen, the drainage filter screen and the drainage port in sequence and is discharged. When drying the sweater, the small T-shaped pin is inserted into the small groove of the cylinder through the small hole, making the cylinder and the drainage system form an integral body. When the piston moves upward, it inhales gas from the one-way valve. When the piston moves downward, it sends out gas, forming a high-speed air flow. Due to the one-way flow characteristic of the one-way valve, the high-speed air flow can only be sent out from the row of spray nozzles, and the sweater is dried at a low temperature after being cooled by passing through the row of spray nozzles. This sweater air dryer dries the sweater by the methods of squeezing dehydration and cold air drying, and this sweater air dryer reasonably utilizes the structure to realize the combination of the two methods of squeezing dehydration and cold air drying on the same device.

[0005] The beneficial effects of the present invention are as follows: It is beneficial to avoid the deformation and damage of the sweater caused by using a centrifugal dehydrator and avoid the damage of the protein fibers in the sweater due to hot air drying. Moreover, the piston type structure used in this sweater air dryer is beneficial to reducing the energy consumption of the device. The screens and filter screens used are all detachable structures, which is convenient for the maintenance and cleaning of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0007] The present invention will be further described below in conjunction with the drawings and embodiments, but the protection scope of the present invention is not limited thereto.

[0008] As Figure 1As shown in the figure, a sweater dryer is characterized by mainly including a dryer main body at the upper part and a drainage system at the lower part. The dryer main body is composed of a cylinder, a piston, a row of spray nozzles, a one-way valve, small grooves, large holes, large grooves, an upper screen, large T-shaped pins and a piston rod. The drainage system is composed of a drainage funnel, a lower screen, a drainage filter screen, small holes, small T-shaped pins and a drainage port. The row of spray nozzles is evenly distributed below the cylinder. Small grooves are arranged on the left and right outer sides of the row of spray nozzles. An upper screen is arranged below the row of spray nozzles. Large T-shaped pins are arranged on the left and right sides of the cylinder respectively. The cylinder and the piston rod can be fixed through the large T-shaped pins. The small T-shaped pins on both sides of the drainage funnel can pass through the small holes on the left and right sides and be fixed with the small grooves. The lower screen, the drainage filter screen and the drainage port are arranged in sequence from top to bottom above the drainage funnel. Before the sweater dryer starts to be used, first place the sweater at the lower screen. The piston is at the limit position of downward movement. Use the large T-shaped pins on the left and right sides of the cylinder to be completely inserted into the large holes on the left and right sides respectively to fix the piston rod. At this time, the piston rod moves up and down, and the sweater dryer starts to operate. Since the piston rod has been fixed with the cylinder as a whole, the cylinder can be driven to move up and down for piston movement to squeeze out the moisture of the sweater placed at the lower screen. The moisture passes through the lower screen and the drainage filter screen from top to bottom and then enters the drainage funnel and is discharged through the drainage port. After squeezing out the moisture of the sweater, stop the operation of the sweater dryer. Then use the small T-shaped pins on the left and right sides of the drainage funnel to be completely inserted into the small holes on the left and right sides respectively and connect with the small grooves on both sides of the row of spray nozzles to fix the cylinder. Pull out the large T-shaped pins on the left and right sides of the cylinder to cancel the fixation between the cylinder and the piston rod. At this time, the piston rod moves up and down, and the sweater dryer starts to operate. When the piston moves upward, air is inhaled from the one-way valve. When the piston moves downward, gas is sent out to form a high-speed air flow. Due to the one-way flow characteristic of the one-way valve, the high-speed air flow can only be sent out from the row of spray nozzles. When the high-speed air flow passes through the row of spray nozzles, it becomes cold air with low temperature and low pressure. When passing through the wet sweater, it cools down and dehumidifies, achieving the effect of cold air drying. After completion, take out the sweater from the lower screen.
