[0016] To make the technical solution and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0017] A rapid airflow drying and draining rack, such as Figures 1-6 As shown, the support frame includes a support frame 1 and supports 6 located on both sides of the bottom of the support frame 1. The support frame 1 is a trapezoidal structure. Inside the support frame 1, there is an air supply chamber 11 and a drying mechanism for supplying air to the air supply chamber 11. Drying area 16 and air drying area 17 are respectively provided on the side plates 12 of the support frame 1. Multiple hollow air ducts 2 are detachably connected to the drying area 16 and the air drying area 17 through the first base 3 and the second base 10, respectively. The position of the drying area 16 corresponds to the air supply chamber 11. The air drying area 17 is located below the drying area 16. Each first base 3 on the drying area 16 is connected to the air supply chamber 11. Multiple air outlets 21 are provided on the upper end and the surrounding side wall of the air duct 2. The air outlets 21 are used for airflow to pass through and dry the glassware.

[0018] By setting up a drying zone 16 and an air-drying zone 17, the air duct 2 of the drying zone 16 is connected to the air supply chamber 11, so that the airflow delivered by the drying mechanism can quickly dry the glassware. For ordinary glassware, such as beakers and test tubes, airflow drying is more efficient; for precision glassware, such as graduated burettes and pipettes, or instruments that are not in urgent need, natural air drying can be used, making the drying rack more practical.

[0019] The support frame 1 includes a top plate and a bottom plate that are arranged horizontally and opposite to each other, two shelf plates 12 that are arranged at an angle and opposite to each other, and two side plates 13 that are arranged vertically and opposite to each other. By arranging the shelf plates 12 at an angle, it is convenient to place more glass instruments and ensure the overall stability. When in use, the shelf plates 12 can be placed against the wall or against the edge of the sink to save space.

[0020] The air duct 2 is designed with a tapered structure with a narrow opening at the top and a wide opening at the bottom, which makes it more stable and less prone to shaking when hanging relatively heavy instruments such as beakers.

[0021] A rubber anti-slip cap 9 is installed at the top of the air duct 2, and the center of the rubber anti-slip cap 9 has a through hole that communicates with the inside of the air duct 2. The rubber anti-slip cap 9 prevents glass instruments hanging on the air duct 2 from falling and protects the inner walls of the glass instruments from impacts. The through hole in the rubber anti-slip cap 9 ensures unobstructed airflow at the top of the air duct 2 and improves the drying effect in the dead corners at the bottom of the instruments.

[0022] A hollow insert is coaxially mounted at the bottom of the duct 2, and the outer peripheral wall of the insert has external threads. The first base 3 includes a first base 31 mounted on the frame plate 12, and a hollow first sleeve 32 is inserted through the first base 31. The bottom end of the first sleeve extends into the air supply cavity 11, and the inner wall of the first sleeve 32 has internal threads that match the insert, so that the insert and the first sleeve 32 are threadedly connected. The quick assembly and disassembly of the duct 2 and the first base 3 and axial positioning are achieved through the screwing connection between the external thread of the insert and the internal thread of the first sleeve.

[0023] The second base includes a second base mounted on the frame plate 12 and a second sleeve mounted on the second base. The bottom end of the second sleeve is closed, and the inner wall of the second sleeve is provided with an internal thread adapted to the insertion pipe, so that the second sleeve can be threadedly connected to the insertion pipe. The connection method between the second base and the air duct is similar to that of the first base.

[0024] The first sleeve 32 and the second sleeve are inclined. Specifically, the inclination angle of the first base 31 and the second base ranges from 20 to 45°.

[0025] The first base 31 and the second base can be fixed to the support frame 1 by bolts or snap-fit ​​connections. The airflow in the air supply chamber 11 is delivered to the air duct through the first sleeve 32 and exits from the air outlet of the air duct. When the air duct 2 does not need to be installed on the first base 3 or the second base, the air duct 2 is removed and the sealing cap 8 is installed on the first sleeve 32 or the second sleeve. The sealing cap 8 is equipped with a rubber sleeve on the top, which can reduce the loss of ineffective air volume, reduce the power consumption of the fan 4, and improve the drying efficiency.

[0026] The drying mechanism includes a fan 4 fixed to the bottom of the support frame 1. A heating channel 5 is provided between the air outlet 21 of the fan 4 and the air supply chamber 11. Multiple insulating tubes are installed in the heating channel 5, and resistance wires 51 are spirally wound on the insulating tubes. When the resistance wires 51 are energized, they heat up, raising the temperature of the airflow passing through them. The heated airflow flows into the air supply chamber 11 and then through the first base 3 to the air duct 2. Specifically, the resistance wires 51 are made of nickel-chromium alloy wire or iron-chromium-aluminum alloy wire.

[0027] A first partition 14 is provided inside the support frame 1, which divides the upper space inside the support frame 1 to form an air supply chamber 11. The heated airflow through the heating channel 5 enters the air supply chamber 11 through the air inlet. A second partition 15 is provided along the center line of the length direction of the first partition 14, which symmetrically divides the air supply chamber 11 into two chambers. Two first air outlets communicating with the heating channel 5 are provided on the first partition 14. The two first air outlets are respectively located on both sides of the second partition 15, and the heated airflow flows into the two chambers respectively, making the airflow direction more uniform.

[0028] The heating channel 5 is a closed channel arranged along the length of the air supply chamber 11. The top surface of the heating channel 5 has two second air supply ports at both ends, connecting to the two first air supply ports of the air supply chamber 11. The bottom surface of the heating channel has a third air supply port in the middle, connecting to the air outlet duct of the fan 4. A resistance wire 51 is positioned between the second and third air supply ports, allowing the airflow generated by the rotation of the fan 4 blades to flow from the third air supply port into the heating channel. After passing through the energized resistance wire, the airflow temperature rises, and then it enters the two chambers of the air supply chamber from the second and first air supply ports, finally flowing out from the air outlet duct.

[0029] A control panel 7 is installed on the side plate 13 of the support frame 1. The control panel 7 includes a switch knob 71, a switch indicator light 72, a hot / cold indicator light 73, and a hot / cold adjustment knob 74. The support frame 1 also has a power plug for connecting to a power source, allowing operators to select the appropriate setting according to experimental needs. Multiple ventilation openings are provided on the bottom and side plate 13 of the support frame 1 to ensure the normal operation of the drying mechanism.

[0030] The support frame 1 is equipped with a thermostat and a timer. When the thermostat detects that the temperature exceeds the threshold, it cuts off the power to the resistance wire 51, stopping the heating airflow. Specifically, the thermostat can be a bimetallic thermostat or a PTC thermostat, and the threshold range can be set to 100-120 degrees Celsius. The timer can be set to the maximum heating duration; after the timer expires, it will forcibly cut off the power to prevent the equipment from overheating due to continuous operation.

[0031] The support 6 includes a water collection trough 61 and two support legs 67 located at the bottom of the water collection trough 61. The two support legs 67 are symmetrically arranged on both sides of the bottom of the water collection trough 61 to support the overall stability of the drain rack. The water collection trough 61 is inclined at the bottom of the frame plate 12. A water outlet 62 is provided at the lowest point of the water collection trough 61. A guide plate 63 is provided on the water collection trough 61 to guide the water flow towards the water outlet 62. The bottom end of the water outlet 62 vertically penetrates the water collection trough 61 and is provided with a water outlet pipe 64. A drain hose 65 with a rubber interface 66 is connected to the water outlet pipe 64. The inclination angle of the guide plate 63 is set to 5-10°, so that the liquid dripping onto the guide plate 63 flows along the direction of the guide plate 63 towards the water outlet 62, and is discharged through the water outlet pipe 64 and the drain hose 65. The other end of the drain hose 65 can be placed in the water collection box or directly in the water tank of the washing station, so that the collected wastewater can be discharged directly, reducing liquid residue and eliminating the need for frequent wiping and cleaning, thus reducing the burden on staff.

[0032] The working principle of this utility model is as follows: In use, first place the drain rack on the operating table. Based on the quantity and specifications of the glassware such as measuring cylinders and beakers to be dried and drained, install the corresponding number of air ducts 2 on the first base 3 of the side rack plates 12, and install sealing caps 8 on the first base 3 or second base 10 where no air ducts 2 are installed. Tilt the measuring cylinders and beakers to be processed onto the air ducts 2 to ensure stability. Turn on the switch knob 71; the switch indicator light 72 will illuminate, indicating the equipment is powered on. Turn on the heat / cold adjustment knob 74; the heat / cold indicator light 73 will illuminate, indicating the airflow drying function is activated. Select drying or natural air drying according to the material and drying requirements of the glassware. During drying, the appropriate outlet temperature and airflow speed can be set by adjusting the heat / cold adjustment knob 74. During use, excess water on the surface of the glassware will drip into the water collection tank 61, be collected by the guide plate 63, flow into the water outlet 62, then through the water outlet pipe 64 into the drain hose 65, and finally drain into the designated collection container.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
