Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically relating to a dehydration and drying machine. Background Technology

[0002] With the improvement of people's living standards, clothes dryers have become increasingly popular, and vacuum dryers have attracted attention due to their unique advantages. Their working principle is as follows: First, a vacuum environment is created by internally drawing a vacuum to form a negative pressure environment lower than atmospheric pressure, reducing the boiling point of water and causing it to evaporate at a lower temperature. Then, the clothes are heated to accelerate the evaporation of moisture. Finally, the evaporated water vapor is quickly extracted by the vacuum pump, condensed in the condenser, and collected or directly discharged. Its significant features include: fast drying speed, low-temperature drying to reduce damage to clothes, low energy consumption and environmental friendliness, prevention of mold and bacteria growth, and a compact size suitable for small apartments.

[0003] Vacuum dryers mainly consist of a vacuum system, a heating system, a drying chamber, a moisture collection system, and a control system. However, they also have some problems in practical applications: 1) The vacuum pump is quite noisy when running, affecting use in noise-sensitive locations or during certain time periods; 2) There are efficiency issues with the heating system. Current technology mainly uses electric heating, and the electric heating elements are generally arranged around the vacuum drying chamber. The air inside the drying chamber is thin and has weak airflow, which limits heat exchange and results in low drying efficiency; 3) In a vacuum environment, there is almost no ventilation inside the drying chamber, and saturated vapor clouds form on the surface of the clothes, hindering moisture evaporation and further reducing the heating and drying efficiency.

[0004] Compared to conventional dryers that take 2-3 hours to dry clothes, vacuum dryers can dry clothes in 1-2 hours. While vacuum dryers offer shorter drying times, there is still room for improvement. Furthermore, in commercial settings, to increase drying efficiency, vacuum levels are often sacrificed and energy consumption is increased, resulting in energy waste, environmental damage, and potential harm to clothing.

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include at least one of those features.

[0027] like Figure 1 As shown in the preferred embodiment of this utility model, this embodiment provides a dehydration and drying machine, including a vacuum dehydration tank 1, a drum 4, a vacuum pump 5, a water collection tank 8, a vacuum cover 10, and a heating element 17. The vacuum cover 10 is installed on top of the vacuum dehydration tank 1 in an openable manner, and the drum is installed in the internal cavity of the vacuum dehydration tank 1. When the vacuum cover 10 is open, clothes to be dehydrated and dried can be placed into the drum 4; when the vacuum cover 10 is closed, a sealed cavity is formed between the vacuum dehydration tank 1 and the vacuum cover 10; a sealing ring 14 is also provided between the vacuum dehydration tank 1 and the vacuum cover 10 to ensure the airtightness of the internal cavity. A vacuum pressure gauge 9 is installed on the vacuum cover 10 to detect the vacuum level of the internal cavity of the vacuum dehydration tank 1.

[0028] In the device provided by this utility model, the bottom of the roller 4 is rotatably connected to the vacuum dehydration tank 1 via a coupling 22 and a rotary bearing seat 23. Specifically, the coupling 22 can be fixed to the output shaft at the bottom of the roller 4 by a key connection or a shrink sleeve connection, and the bottom of the rotary bearing seat 23 is fixed to a support position at the bottom of the inner cavity of the vacuum dehydration tank 1. The bottom of the coupling 22 and the top of the rotary bearing seat 23 are connected by rotatable rolling elements, so that the roller 4 is rotatably connected inside the vacuum dehydration tank 1.

[0029] In the device provided by this utility model, several water-permeable holes 3 are opened on the wall of the roller 4. In order to facilitate the outflow of water thrown out after the roller 4 rotates, the bottom of the vacuum dehydration tank 1 in this embodiment is set with a structure that slopes from the outside to the inside, and a drain pipe 25 is set at the lowest point of the bottom of the vacuum dehydration tank 1. The outlet of the drain pipe 25 is connected to the water collection tank 8. An air extraction port and a water discharge port are opened on the water collection tank 8, wherein the air extraction port is connected to the vacuum pump 5 through a vacuum extraction pipe 6. A vacuum valve 7 for controlling the opening and closing is set on the vacuum extraction pipe 6. In addition, a pipe communicating with the outside is set at the water discharge port of the water collection tank 8, and a water discharge valve 24 for controlling the outflow of water in the water collection tank 8 is also set on the pipe.

[0030] In the device provided by this utility model, a jet nozzle 15 is provided on the upper part of the side wall of the vacuum dehydration tank 1, and an atomizing nozzle 13 is provided on the vacuum hood 10. The atomizing nozzle 13 is connected to the heating element 17 through a first heating gas pipe 26, and the jet nozzle 15 is connected to the heating element 17 through a second heating gas pipe 27. In this embodiment, a gas supply switch valve 11 and a gas supply throttle 12 are sequentially provided on the first heating gas pipe 26 from the atomizing nozzle 13 toward the heating element 17. A jet switch valve 18 and a jet throttle 16 are sequentially provided on the second heating gas pipe 27 from the jet nozzle 15 toward the heating element 17.

[0031] In this embodiment, the heating element 17 is a heating pump that converts electrical energy into heat energy by energizing it. A T-connector is fixedly provided at the output end of the heating element 17, which is connected to the first heating gas pipe 26 and the second heating gas pipe 27 respectively.

[0032] The side wall of the drum 4 is also provided with an impact plate 2, and the position of the impact plate 2 corresponds to the jet nozzle 15 provided on the side wall of the vacuum dehydration tank 1. The jet gas from the jet nozzle 15 impacts the impact plate 2, providing rotational power for the drum 4.

[0033] In the device provided by this utility model, the lower part of the side wall of the vacuum dehydration tank 1 is also provided with an air blowing atomizing nozzle 20. The air blowing atomizing nozzle 20 is connected to the outside through a pipe provided with an air blowing switch valve 21 and an air blowing throttle 19.

[0034] The following is a method for using the above-mentioned spin-dryer combo for spin-drying clothes, as detailed below:

[0035] (1) Place the clothes to be dried into the drum 4 inside the vacuum dehydration tank 1, and cover it with the vacuum cover 10 to form a sealed space inside the vacuum dehydration tank 1 and the vacuum cover 10. Close the air supply switch valve 11, the jet switch valve 18, the air blowing switch valve 21 and the water drain valve 24, and open the vacuum valve 7.

[0036] (2) Start the vacuum pump 5 and heating element 17. After the pressure inside the vacuum dehydration tank 1 drops to near vacuum, open the jet switch valve 18. The airflow heated by the heating element is drawn into the vacuum dehydration tank 1 due to the pressure difference between the inside and outside of the vacuum dehydration tank 1, and impacts the impact plate 2, causing the roller 4 to rotate. The roller 4, under the action of centrifugal force, throws out the water attached to the clothes and slides down the inner wall of the vacuum dehydration tank 1, and flows into the water collection tank 8 through the drain pipe 25, thus achieving preliminary dehydration of the clothes.

[0037] (3) After the clothes have undergone initial dehydration, the jet valve 18 is closed to increase the vacuum level inside the vacuum dehydration tank 1. Under negative pressure, the remaining moisture on the surface of the clothes boils and evaporates at room temperature, forming gaseous water vapor. As the moisture evaporates and absorbs heat, the temperature inside the vacuum dehydration tank 1 decreases. At this time, the air replenishment valve 11 and the jet valve 18 are intermittently opened to replenish a small amount of hot air into the tank. On the one hand, the clothes are heated, which accelerates the evaporation process; on the other hand, the replenished hot air allows the air inside the tank to circulate, carrying away the saturated water vapor on the surface of the clothes and expelling it to the outside through the vacuum pump 5, thereby reducing the water vapor saturation inside the tank. This cycle is repeated to achieve rapid and efficient drying of the clothes.

[0038] The drum 4 rotates under the action of the jet gas, causing the clothes to adhere to the drum wall due to centrifugal force, resulting in a relatively dense state. At this time, the jet valve 18 can be turned off or closed to reduce the effect of centrifugal force, while the air blowing valve 21 can be opened appropriately. Under the action of negative pressure, outside air is drawn into the vacuum dehydration tank 1 through the air blowing valve 21. The air directly impacts the drum wall under the action of wind force, and then impacts the clothes through the water permeable holes 3, blowing the clothes to fluff them up, while also blowing away some water vapor.

[0039] The above embodiments are merely preferred solutions of this utility model, and are not intended to limit this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model. Therefore, all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
