Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and in particular to a rapid clothing drying device based on hot air circulation and its working method. Background Technology

[0002] The history of dryers dates back to the late 19th century. The earliest dryers used a mechanism called a "drying tumbler," which utilized steam heating to dry clothes. With the development of electrical technology, electric dryers began to appear in the early 20th century. The basic working principle of a dryer is to use hot air to expel moisture from clothes, causing them to dry quickly. This is typically achieved through heat generated by a heating element (resistance wire or a natural gas burner). Dryers are also equipped with fans to ensure that hot air is evenly distributed throughout the clothes, quickly drying damp garments and fabrics. By applying hot air and a ventilation system, moisture is removed from clothes, leaving them dry and comfortable. This saves time compared to air drying, and is particularly useful in humid or cold climates.

[0003] However, during the drying process, the clothes absorb a lot of water, causing them to hang down and stick together, resulting in poor drying efficiency. In addition, the hot air is directly discharged during the drying process, and the heat energy is not well utilized. Summary of the Invention

[0006] As a further improvement to the above technical solution:

[0007] Preferably, the drying unit has the following structure: it includes a first tank and a second tank, both of which are provided with an adsorption layer; the top of the first tank and the second tank are connected by an air outlet pipe, which has a “┎┒” shape and an air outlet in the middle; the bottom of the first tank and the second tank are connected by an air inlet pipe, which has a “┖┚” shape and an air inlet in the middle.

[0008] Preferably, a first pneumatic check valve is provided between the first tank and the air outlet, and a second pneumatic check valve is provided between the second tank and the air outlet. A regeneration branch is provided between the air inlet side of the first pneumatic check valve and the air inlet side of the second pneumatic check valve. The regeneration branch has a “┖┚” shaped pipeline structure. A flow regulating valve is provided on the regeneration branch.

[0009] Preferably, a first solenoid valve is provided between the first tank and the air inlet, and a second solenoid valve is provided between the second tank and the air inlet; the air inlet side pipe of the first solenoid valve extends outward to form a first exhaust port, and a third solenoid valve is provided on the air inlet side of the first exhaust port; the air inlet side pipe of the second solenoid valve extends outward to form a second exhaust port, and a fourth solenoid valve is provided on the air inlet side of the second exhaust port.

[0010] Preferably, the outer shell has the following structure: it includes a box body, a mesh screen is provided at the bottom of the box body, and a water collection tank is installed under the mesh screen; a drain pipe is installed on one side of the water collection tank, the drain pipe passes through the side wall of the box body and extends to the outside, a door is installed at the front of the box body, and a switch valve is provided on the drain pipe.

[0011] Preferably, the structure of the vibration unit is as follows: it includes a base, a slider is installed inside the base, and a motor is installed above the slider; first springs are symmetrically installed on both sides of the slider, and water-blocking covers are matched above the first springs; the output shaft of the motor is connected to a rotating shaft, the rotating shaft is vertically arranged, an eccentric block is provided on the rotating shaft, a clothes rack is arranged horizontally at the top of the rotating shaft, multiple clothes rack supports are provided on the clothes rack, sleeves are provided at both ends of the clothes rack, and second springs are installed inside the sleeves; one end of the water-blocking cover is fixed to the outermost side of the base, and the other end is connected to the outer edge of the slider; a limiting member is provided between every two clothes rack supports.

[0012] A method for operating a rapid clothes drying device based on hot air circulation, comprising the following steps:

[0013] Step 1: Place the clothes on the clothes rack and close the trunk door;

[0014] Step 2: Turn on the motor on the slider to drive the shaft to rotate. At this time, the eccentric block is driven to rotate, causing the slider to move back and forth along the axis of the base. The clothes rack moves back and forth synchronously with the slider. Under the action of the first spring on both sides of the slider and the second spring at both ends of the clothes rack, the slider and the clothes rack are continuously reset, thus generating vibration.

[0015] Step 3: The fan blows the heated air in the heating chamber through the air outlet onto the clothes inside the chamber, and then draws the hot air from inside the chamber back into the heating chamber through the air supply pipe. The drying unit on the air supply pipe dries the air, realizing hot air circulation.

[0016] Step 4: Water dripping from the clothes falls through the strainer into the water collection tank. When the tank is full, open the valve to drain the water through the drain pipe.

[0017] Preferably, in step three, the working steps of the drying unit are as follows:

[0018] Step 1: Adsorption

[0019] The first solenoid valve is open and the second solenoid valve is closed. At this time, the humid and hot air in the chamber enters the first tank through the air inlet. The humid and hot air flows from bottom to top through the adsorption layer and becomes dry and hot air after drying. Most of the dry and hot air passes through the first pneumatic check valve and is discharged from the air outlet and re-enters the chamber. A small part of the dry and hot air enters the second tank through the regeneration branch.

[0020] Step 2: Regeneration

[0021] A small portion of the dry, hot air enters the second tank through the regeneration branch and dries the adsorbent in the adsorption layer inside the second tank from top to bottom, restoring the drying capacity of the adsorbent in the second tank. At this time, the second solenoid valve is in the closed state and the fourth solenoid valve is in the open state. The dry, hot air restores the second tank to humid, hot air, and then discharges it into the atmosphere through the fourth solenoid valve.

[0022] Step 3: Switch

[0023] After the adsorbent in the second tank is regenerated, the fourth solenoid valve closes, the second solenoid valve opens, the first solenoid valve closes, and the third solenoid valve opens, thus completing the switching of the working states of the first and second tanks; at this time, the second tank enters the adsorption state, and the first tank enters the regeneration state.

[0024] The beneficial effects of this invention are as follows:

[0025] This invention features a compact structure. Through the air circulation drying unit, the fan draws the hot air inside the chamber back into the chamber, achieving hot air circulation and avoiding the waste of heat energy, making the drying of clothes more energy-efficient and effective. At the same time, the drying unit of this invention can continuously convert the humid and hot air in the chamber into dry and hot air, greatly improving the heating efficiency.

[0026] The present invention also has the following advantages:

[0027] (1) The present invention achieves vibration of clothes on the clothes hanger by rotating the shaft and driving the setting of the eccentric block, which avoids the clothes sticking together, increases the drying area of ​​the clothes, and the shaking accelerates the drop of moisture from the clothes, ensuring the drying efficiency of the clothes. In addition, a limiting part is set between every two clothes hangers to prevent the clothes hangers from gathering together due to shaking.

[0028] (2) By setting a water collection tank at the bottom of the box, the present invention can collect the water dripping during the drying process of clothes and finally discharge it through the switch valve, which is convenient and quick.

[0029] (3) The air circulation drying unit of the present invention has air outlet holes evenly distributed on the bottom surface of the heating box, so that the air outlet is more uniform and can dry clothes thoroughly. Attached Figure Description

[0049] The working method of the clothes rapid drying device based on hot air circulation in this embodiment includes the following steps:

[0050] Step 1: Place the clothes on the clothes rack 208 and the clothes support 209 and close the box door 102;

[0051] Step 2: Turn on the motor 204 on the slider 202 to drive the rotating shaft 206 to rotate. At this time, the eccentric block 207 is driven to rotate, causing the slider 202 to move back and forth along the axis of the base 201. The clothes rack 208 moves back and forth synchronously with the slider 202. Under the action of the first spring 203 on both sides of the slider 202 and the second spring 211 at both ends of the clothes rack 208, the slider 202 and the clothes rack 208 are continuously reset, thereby generating vibration.

[0052] Step 3: The fan 303 blows the heated air in the heating box 301 through the air outlet 302 onto the clothes in the box 101, and then draws the hot air in the box back into the heating box 301 through the air supply pipe 304. The drying unit 305 on the air supply pipe 304 dries the air, realizing hot air circulation.

[0053] Step 4: Water from the clothes falls through the strainer 103 into the water collection tank 104. When the water collection tank 104 is full, the switch valve 105 is opened to allow the water in the water collection tank 104 to be discharged through the drain pipe 106.

[0054] In this embodiment, the working steps of the drying unit 305 in step three above are as follows:

[0055] Step 1: Adsorption

[0056] The first solenoid valve 30511 is in the open state, and the second solenoid valve 30512 is in the closed state. At this time, the humid and hot air in the housing 101 enters the first tank 30501 from the air inlet 30510. The humid and hot air flows from bottom to top through the adsorption layer 30503 and becomes dry and hot air after drying. Most of the dry and hot air passes through the first pneumatic check valve 30505 and is discharged from the air outlet 30509 and re-enters the housing 101. A small part of the dry and hot air enters the second tank 30502 after passing through the regeneration branch 30507.

[0057] Step 2: Regeneration

[0058] A small portion of the dry, hot air enters the second tank 30502 through the regeneration branch 30507 and dries the adsorbent in the adsorption layer 30503 inside the second tank 30502 from top to bottom, restoring the drying capacity of the adsorbent in the second tank 30502. At this time, the second solenoid valve 30512 is in the closed state and the fourth solenoid valve 30514 is in the open state. The dry, hot air restores the second tank 30502 to humid, hot air, and then discharges it into the atmosphere through the fourth solenoid valve 30514.

[0059] Step 3: Switch

[0060] After the adsorbent in the second tank 30502 has been regenerated, the fourth solenoid valve 30514 is closed, the second solenoid valve 30512 is opened, the first solenoid valve 30511 is closed, and the third solenoid valve 30513 is opened. At this time, the working state of the first tank 30501 and the second tank 30502 is switched. The second tank 30502 enters the adsorption state, and the first tank 30501 enters the regeneration state.

[0061] In this embodiment, the adsorbent in the adsorption layer 30503 can be activated alumina.

[0062] This invention utilizes waste heat. The fan 303 dries the hot and humid air inside the chamber 101 and sends it back into the chamber 101, achieving hot air circulation and avoiding waste of heat energy. This makes drying clothes more energy-efficient and effective. Moreover, the first chamber 30501 and the second chamber 30502 operate independently, and their working states can be switched by a solenoid valve to ensure continuous drying of the hot and humid air. In addition, this invention also uses a rotating shaft 206 to drive an eccentric block 207, which vibrates the clothes on the clothes rack 208, preventing the clothes from sticking together, increasing the drying area, and accelerating the removal of moisture from the clothes, thus ensuring efficient drying.

[0063] The above description is an explanation of the present invention and not a limitation thereof. The scope of the present invention is defined by the claims. Within the scope of protection of the present invention, any form of modification may be made.

The working states of the first tank (30501) and the second tank (30502) are switched. At this time, the second tank (30502) enters the adsorption state, and the first tank (30501) enters the regeneration state.
