DETAILED DESCRIPTION

[0021] The following is a combination of the appended examples of the present invention Figure 1-Figure 5 The technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] like Figure 1 As shown, the utility model provides a technical solution: a vacuum drying device for clothes, comprising an outer shell 1, a vacuum device 2 fixed inside the outer shell 1, a hanger 3 fixed inside the outer shell 1, a microwave heating mechanism 4 fixed on both sides of the outer shell 1, and a sealing cover 5 fixed on the upper end of the outer shell 1; the outer shell 1 is used to install and protect the internal equipment of the device, and divides the internal space into two spaces, the upper space for storing clothes, and the lower space for installing equipment of the vacuum mechanism 2, the vacuum device 2, after vacuuming the space where the upper clothes are placed, discharges the evaporated and condensed water, the hanger 3 is used to store clothes, and is divided into four layers. Too much stacking of clothes leads to low water evaporation efficiency, the microwave heating mechanism 4 is a low-power laser, which mainly ensures that water can reach its boiling temperature at 5Kpa, and the sealing cover 5 forms a sealed space with the outer shell 1 to prevent air from entering.

[0023] like Figure 2As shown, the vacuum mechanism 2 includes a compression tank bracket 201 fixed to the bottom of the housing 1, a vacuum pump 202 fixed to the middle of the compression tank bracket 201, a first air inlet pipe 203 fixed to the left side of the vacuum pump 202, a three-way joint 205 fixed to the upper end of the first air inlet pipe 203, a first one-way valve 204 fixed to the lower end of the first air inlet pipe 203, a second air inlet pipe 206 fixed to the right side of the three-way joint 205, a compression tank 207 fixed to the upper end of the compression tank bracket 201, a second one-way valve 208 fixed to the lower end of the compression tank 207, a pressure relief pipe 209 fixed to the lower end of the second one-way valve 208, a pressure relief port 210 fixed to the right side of the pressure relief pipe 209, and a pressure relief port 211 fixed to the compression tank 207. The third one-way valve 211 at the upper end and the air outlet pipe 212 fixed in the middle of the third one-way valve 211; the compression tank bracket 201 is used to support and fix the compression tank and related components to ensure that they remain stable and fixed during operation. The vacuum pump 202 is used to extract the air inside the shell 1 to form a low-pressure or vacuum environment, thereby accelerating the evaporation of moisture in the clothes and improving the drying efficiency. The first air inlet pipe 203 connects the vacuum pump 202 and the three-way joint 205 to provide a channel for air circulation to ensure that the vacuum pump 202 can effectively extract air. The first one-way valve 204 is installed at the lower end of the first air inlet pipe 203 to ensure that the air can only flow in the direction of the vacuum pump 202 to prevent the air from flowing back to the vacuum pump 202. The cavity is provided with a low-pressure environment, and the three-way joint 205 is used to connect the first air inlet pipe 203, the second air inlet pipe 206 and the vacuum pump 202 together to realize the confluence and diversion of multiple pipelines and ensure the normal operation of the vacuum system. The second air inlet pipe 206 is connected to the three-way joint 205 and the compression tank 207 to ensure that the vacuum pump 202 can effectively extract the air in the compression tank 207 to maintain the vacuum state. The compression tank 207 is used to store and adjust the vacuum environment, play a buffering and stabilizing role, ensure the continuous stability of the vacuum state and ensure that there is new air in the microwave heating mechanism 4 for heat dissipation. The second one-way valve 208 is installed at the lower end of the compression tank 207 to ensure that air can only be discharged from the compression tank 2 07 flows toward the pressure relief pipe to prevent air from flowing back into the compression tank 207 and maintain the pressure environment in the compression tank 207. The pressure relief pipe 209 and the pressure relief port 210 are used together to release the pressure in the compression tank 207 and discharge moisture when needed to ensure the safe operation of the equipment. The third one-way valve 211 is installed at the upper end of the compression tank 207 to ensure that air can only flow from the compression tank 207 to the air outlet pipe to prevent air from flowing back into the compression tank 207 and maintain the pressure environment in the compression tank 207. The air outlet pipe 212 connects the third one-way valve 211 and the outside world to ensure that the air in the compression tank 207 can be discharged smoothly, and is connected to the microwave heating mechanism 4 to pass compressed air to dissipate heat for the microwave heating mechanism 4.

[0024] In general, the location where the clothes are placed is evacuated by the vacuum pump 202 to lower the boiling point of the water, and the water is heated by the microwave heating mechanism 4. This design does not require the vacuum pump 202 and the vacuum heating device 4 to have a large power, thereby reducing energy consumption. When the vacuum degree of the location where the clothes are placed meets the requirement, the first one-way valve 204 allows air to enter. At this time, the water flows down along the first air inlet pipe 203 and the second air inlet pipe 206, and enters the compression tank 207 together with the outside air, and is then discharged by the second one-way valve 208. This design can reduce energy consumption while efficiently discharging water.

[0025] like Figure 3 As shown, the microwave heating mechanism 4 includes a microwave housing 401, an air intake fan 402 fixed in the middle of the microwave housing 401, an exhaust fan 403 fixed in the middle of the microwave housing 401, a magnetron 404 fixed on the side of the microwave housing 401, and heat dissipation fins 405 fixed on the outside of the magnetron 404. The microwave housing 401 plays a role in gathering microwaves and also needs to resist external pressure after vacuuming the position where the clothes are placed. The air intake fan 402 sends air into the area where the magnetron 404 is located, and the exhaust fan 403 discharges the internal air to form a circulation to quickly discharge heat. The magnetron 404 is used to generate microwaves. The heat dissipation fins 405 are arranged in close proximity to the magnetron 404 to conduct heat away. When air flows through, the heat is efficiently dissipated into the air.

[0026] like Figure 4 As shown, four pairs of support rods 301 are provided in the clothes hanger 3, and clothes hangers 302 are placed on the upper ends of the support rods 301. The support rods 301 are arranged at intervals to support the clothes hangers 302, so that there are gaps between the clothes, which can better evaporate the moisture in the clothes.

[0027] like Figure 4 As shown, the support rods 301 are arranged in a stepped manner. Such a stepped arrangement of the support rods 301 makes it easy to take and place the hanger 302 without getting stuck.

[0028] like Figure 5 As shown, the microwave emitting end panel of the microwave housing 401 is a glass panel 4012, and the rear end is a metal plate 4011. A first vent 4013 is opened at the bottom, and a second vent 4014 is opened horizontally in the middle. The metal plate 4011 has a certain curvature in the middle to emit microwaves in a fixed direction. The glass panel 4012 has good pressure resistance and can pass microwaves. The first vent 4013 is arranged at the bottom of the microwave housing 401 to discharge the hot air exhausted by the exhaust fan 403, so that the hot air enters the next cycle as little as possible. The second vent 4014 is used for air to flow between the two magnetrons 404 to form a circulation.

[0029] like Figure 2As shown, the first one-way valve 204 conducts air into the first air inlet pipe 203, and the second one-way valve 208 and the third one-way valve 211 both conduct air outward from the compression tank 207. The first one-way valve 208 conducts the smallest pressure, while the second one-way valve 208 conducts the largest pressure. The first one-way valve 204 is used to introduce outside air into the lower end of the first air inlet pipe 203 when the vacuum degree at the clothing placement position reaches the required level. The air is pumped into the compression tank 207 by the vacuum pump 202. The flow of air drives the water flowing into the first air inlet pipe 203 to flow, and the water is also pumped into the compression tank 207. When the pressure in the compression tank 207 reaches the conduction pressure of the third one-way valve 211, air is introduced into the microwave heating mechanism 4 for heat dissipation. As the water content in the compression tank 202 increases, the pressure in the compression tank 202 increases, and then the second one-way valve 208 is opened to discharge the water and air.

[0030] Working principle:

[0031] During operation, the clothes are first spread flat on the hanger 3, covered with the sealing cover 5, and the microwave heating mechanism 4 and the vacuum pump 207 are started. When the vacuum pump 202 draws the vacuum degree of the clothes storage position to about 10KPa, the moisture in the clothes begins to boil and condenses on the inner wall of the shell 1, and is discharged along the first air inlet pipe 203 and the second air inlet pipe 206. At this time, the first one-way valve 204 is opened, and air and water continue to be pumped into the compression tank 207. When the pressure in the compression tank 207 reaches a threshold, the third one-way valve 211 is opened, and compressed air is filled into the microwave heating mechanism 4 for heat dissipation. As the water level in the tank rises, the pressure in the tank increases. When it reaches the threshold of the second one-way valve 208, the second one-way valve 208 is opened. Since water is deposited inside the tank, it will be discharged first.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
