Description

Technical Field

[0001] This utility model relates to the field of experimental equipment, and more specifically, to a vessel drying device. Background Technology

[0002] Laboratory experiments involve the use of numerous glasswares, which need to be washed and dried after use for future use. Typically, the washed glasswares are laid upside down on the lab bench to air dry, which is time-consuming, takes up space, and is inconvenient for experimental operations. To address this, researchers have designed a drying rack with multiple finely divided supports. Washed glasswares are hung on these supports, and airflow is directed through them to quickly dry the glasswares.

[0003] However, existing drying racks blow air from all the sub-brackets when they are blowing air. If some sub-brackets do not have any dishes hanging on them, it will result in wasted airflow and reduce the airflow to the sub-brackets with dishes hanging on them. Utility Model Content

[0004] This invention provides a dish drying device that solves the problem of wasted airflow in existing drying racks.

[0005] The embodiments of this utility model can be implemented as follows:

A branch pipe damper is installed at the connection between the branch pipe and the main air duct. The branch pipe damper is used to open or close the connection between the main air duct and the branch pipe.

[0009] The force transmission rod is installed inside the branch pipe. One end of the force transmission rod is connected to the branch pipe damper, and the other end of the force transmission rod extends out of the branch pipe. The end of the force transmission rod extending out of the branch pipe is used to support the vessel. Under its own weight, the vessel pushes open the branch pipe damper, so that the branch pipe is connected to the main air duct.

[0010] Optionally, the branch damper is located inside the main duct, and an elastic element is connected to the branch damper. The elastic element is also connected to the branch duct, so that the elastic element can drive the branch damper to rotate and reset.

[0020] This utensil drying device includes a main air duct, branch pipes, and a transmission rod. The branch pipes are connected to and communicate with the interior of the main air duct, and are equipped with air outlets. A branch pipe damper is located at the connection point between the branch pipe and the main air duct, used to open or close the connection between the two. The transmission rod is located inside the branch pipe, with one end connected to the branch pipe damper and the other end extending out of the branch pipe. This extended end supports the utensil. When a utensil is hung on the end of the transmission rod, its own weight pushes the transmission rod to move, and the branch pipe damper connected to the transmission rod is also pushed, thus opening the connection between the branch pipe and the main air duct. Airflow can enter the branch pipe from the main air duct and then exit from the air outlet, quickly drying the hung utensil.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0035] As described in the background section, laboratory glassware needs to be cleaned after use, and then quickly dried and placed in designated storage cabinets to prevent it from occupying the lab bench, interfering with experimental operations, or being accidentally broken. Currently, most glassware is still air-dried upside down on the lab bench after cleaning, which is time-consuming and requires space on the lab bench. To address this, researchers have designed drying ovens, which can quickly dry glassware. However, the temperature in drying ovens is generally high, and some glassware (such as glassware) will expand and contract under high temperatures. Repeated expansion and contraction of these glassware can affect their lifespan and precision.

[0036] To address the problems with the drying oven, researchers continued to improve and designed a drying rack. This rack includes multiple subdivided supports where washed dishes are hung. These supports are connected to a main frame, which blows airflow onto them, quickly drying the dishes. However, this drying rack still has a problem: when the main frame supplies air to the subdivided supports, it blows airflow onto all of them simultaneously. This means that airflow will still be emitted even when some subdivided supports have no dishes, resulting in wasted airflow and reduced airflow to other subdivided supports with dishes, causing additional airflow loss.

[0037] Based on the above problems, this utility model provides a utensil drying device that can solve the above problems and avoid airflow waste and unnecessary air power loss. It will be described in detail below.

[0038] Please refer to Figures 1 to 3 The utensil drying device includes a main air duct 1, a branch pipe 2, and a force transmission rod 21. The main air duct 1 is connected to the airflow. The branch pipe 2 is connected to the main air duct 1 and communicates with the interior of the main air duct 1. The branch pipe 2 is provided with an air outlet 20. A branch pipe damper 22 is provided at the connection between the branch pipe 2 and the main air duct 1. The branch pipe damper 22 is used to conduct or block the connection between the main air duct 1 and the branch pipe 2. The force transmission rod 21 is located inside the branch pipe 2. One end of the force transmission rod 21 is connected to the branch pipe damper 22, and the other end of the force transmission rod 21 extends out of the branch pipe 2. The end of the force transmission rod 21 extending out of the branch pipe 2 is used to support the utensil, that is, the utensil is hung on the end of the force transmission rod 21.

[0039] When a vessel is hung on the end of the transmission rod 21, the vessel's own weight will push the transmission rod 21 to move, and the branch pipe damper 22 connected to the transmission rod 21 will also be pushed, thereby connecting the branch pipe 2 to the main air pipe 1. Airflow can enter the branch pipe 2 from the main air pipe 1 and then be discharged from the air outlet 20 to quickly dry the hung vessel. The transmission rod 21 without a vessel hanging on it will not move, and the branch pipe damper 22 will not rotate. The branch pipe damper 22 blocks the connection between the branch pipe 2 and the main air pipe 1, thus preventing airflow waste and unnecessary airflow loss.

[0040] It should be noted that in this embodiment, the main air duct 1 is set vertically relative to the ground, and the branch duct 2 is connected to the main air duct 1 at an angle, with the end of the branch duct 2 away from the main air duct 1 being higher than the end connected to the main air duct 1. When airflow is connected from the lower end of the main air duct 1, the airflow can flow upward along the internal cavity of the main air duct 1. If the branch duct damper 22 between the branch duct 2 and the main air duct 1 is pushed open, the airflow from the main air duct 1 can enter the branch duct 2 and then be discharged from the air outlet 20 on the branch duct 2. The discharged airflow blows towards the hung utensils, allowing the utensils to dry quickly.

[0041] The angle between the branch pipe 2 and the main air duct 1 is generally between 10° and 45°. In this embodiment, the angle between the branch pipe 2 and the main air duct 1 is 30°.

[0042] Furthermore, the connection between branch pipe 2 and main air duct 1 is sealed with sealant to prevent air leakage.

[0043] The air outlet 20 on the branch pipe 2 can blow air into the inside of the vessel or onto the outer wall of the vessel, thus accelerating the drying speed of the vessel. Multiple air outlets 20 can be set on the branch pipe 2, and the multiple air outlets 20 are located at different positions on the branch pipe 2. The opening direction of the air outlet 20 is facing one end of the vessel, so that the exhaust airflow blows onto the vessel, which can quickly dry the vessel.

[0044] refer to Figure 4 The branch damper 22 is installed inside the main duct 1, and the branch damper 22 is rotatably connected to the main duct 1 via a hinge. The branch damper 22 is an arc-shaped plate, and an elastic element 23 is connected to the branch damper 22. The elastic element 23 is also connected to the branch duct 2, so that the elastic element 23 can drive the branch damper 22 to rotate and return to its original position. The elastic element 23 can be a spring or an elastic rope.

[0045] For example, the interior of branch pipe 2 is equipped with a cylindrical protrusion. An elastic rope is connected to the upper side of branch pipe damper 22, with the other end of the elastic rope connected to the inner wall of branch pipe 2 and the other end of the elastic rope passing around the outer wall of the protrusion and connecting to branch pipe damper 22. The end of force transmission rod 21 is connected to the lower middle part of branch pipe damper 22. When a vessel is hung on the end of force transmission rod 21, the weight of the vessel pushes branch pipe damper 22 to rotate, the elastic rope is stretched, branch pipe damper 22 is pushed open, and branch pipe 2 is connected to main air pipe 1, allowing airflow to enter branch pipe 2 and quickly dry the vessel. When the vessel is removed, the rebound force of the elastic rope pulls branch pipe damper 22 back, re-sealing branch pipe 2 and main air pipe 1, avoiding airflow waste and air power loss.

[0046] It is worth mentioning that when selecting elastic ropes or springs, the elastic force of the selected elastic ropes or springs should not only be sufficient to reset the branch pipe damper 22 to close the branch pipe 2 and the main air pipe 1, but also sufficient to ensure that the weight of the vessel can overcome the elastic force of the elastic ropes or springs to push the branch pipe damper 22 open.

[0047] In this embodiment, a main air duct 1 is connected to multiple branch pipes 2. In order to prevent the containers on the multiple branch pipes 2 on the main air duct 1 from colliding with each other, and also to facilitate the use of the experimental personnel, the multiple branch pipes 2 are respectively set at different heights and different positions of the main air duct 1.

[0048] Refer again Figure 1 The utensil drying device also includes a housing 3, and the lower end of the main air duct 1 is connected to the housing 3.

[0049] The upper surface of the housing 3 is provided with a collecting ramp 30. An opening is located in the middle of the collecting ramp 30, which is the lowest point of the collecting ramp 30. A liquid collection tank is located below the opening and is located inside the housing 3. The lower end or outer wall of the main air duct 1 is connected to the collecting ramp 30. Water droplets dripping from the container fall onto the collecting ramp 30 and then collect in the liquid collection tank. When multiple main air ducts 1 are arranged on the housing 3, multiple branch liquid collection tanks 31 are correspondingly provided. Each branch liquid collection tank 31 is connected to a liquid guide pipe 32, and the other end of the liquid guide pipe 32 is connected to the main liquid collection tank 33.

[0050] The utensil drying device also includes a ventilation system, which supplies air to the main air duct 1 and branch duct 2.

[0051] The ventilation system includes a fan 40 and a ventilation duct 4. One end of the ventilation duct 4 is connected to the air outlet of the fan 40, and the other end of the ventilation duct 4 is connected to and communicates with the lower end of the main air duct 1. Since the lower end of the main air duct 1 is located in the branch liquid collection tank 31, the ventilation duct 4 needs to pass through the branch liquid collection tank 31 to connect with the main air duct 1. Therefore, in order to prevent leakage between the ventilation duct 4 and the branch liquid collection tank 31, the joint between the ventilation duct and the branch liquid collection tank 31 is sealed with waterproof sealant.

[0052] Furthermore, a wind speed regulator 41 and a plug 401 are provided on the conductive wire of the fan 40. The wind speed regulator 41 is located between the plug 401 and the fan 40. The wind speed regulator 41 can change the air supply intensity of the fan 40 by changing the current in the conductive wire, so as to adapt to drying the utensils.

[0053] When the utensils requiring rapid drying are not affected by thermal expansion and contraction, a heater 5 can be installed at the air outlet of the fan 40. The heater 5 is used to heat the airflow, increase the airflow temperature, and accelerate the drying speed of the utensils. The heater 5 can be an electric heating wire, and a temperature control switch 50 is also installed on the conductive wire connected to the heater 5 to control the start and stop of the electric heating wire. Of course, the heater 5 can also be implemented using other equipment or devices.

[0054] To accurately control the airflow temperature inside the main duct 1, a temperature sensor 6 is installed inside the main duct 1 to detect the airflow temperature. Correspondingly, a controller is installed inside the housing 3, and the controller is communicatively connected to both the temperature sensor 6 and the temperature control switch 50.

[0055] As an example, the controller can be a PLC module and programmed to preset the airflow temperature range. When temperature sensor 6 detects that the airflow temperature is low, the controller determines whether the airflow temperature is within the preset range based on the data transmitted by temperature sensor 6. If it is lower than the preset minimum temperature, the controller instructs temperature control switch 50 to close, and heater 5 starts heating the airflow. If the airflow temperature detected by temperature sensor 6 is higher than the preset maximum temperature, the controller instructs temperature control switch 50 to open, and heater 5 stops heating, thus ensuring that the discharged airflow is always within a certain temperature range.

[0056] The type and model of the temperature sensor 6 can be selected by the user, and the controller can also be a microcontroller or a chip programmable controller. This embodiment does not impose any limitations.

[0057] In this embodiment, an adjustable damper 10 is provided at the top of the main air duct 1 to facilitate the exhaust of hot air inside after the vessel has been completely dried. In other embodiments, the top of the main air duct 1 may be closed.

[0058] In this embodiment, the ventilation pipe 4, the branch liquid collection tank 31, the liquid guide pipe 32, the main liquid collection tank 33, the fan 40 and the heater 5 are all located inside the housing 3.

[0059] Of course, in order to facilitate the replacement of a certain component inside the housing 3, an inspection door 34 is provided on the side of the housing 3, through which the component can be replaced or repaired.

[0060] In this embodiment, both the main duct 1 and the branch duct 2 can be made of plastic with a certain degree of hardness, such as PVC pipe, and the diameter of the main duct 1 is larger than the diameter of the branch duct 2.

[0061] For example, the main duct 1 has a diameter of 50mm and a length of 70cm. Starting from the top, it has symmetrical 2cm holes in four directions, and holes are made at 20cm intervals along the height, for a total of 12 holes, used to connect to branch duct 2. Branch duct 2 has a diameter of 16mm and a length of 16cm. The air outlets on branch duct 2 are arranged in a quincunx pattern, with each outlet having a diameter of 5mm and a spacing of 4cm between adjacent outlets.

[0062] Of course, the main duct 1 and the branch duct 2 can also be made of other materials, and the processing parameters can be designed according to actual conditions, without any restrictions.

[0063] Working principle of the drying device in this embodiment of the utility model:

[0064] After cleaning, the vessels are hung on branch pipe 2. The water droplets on the vessels fall onto the collecting slope 30 and then pass through the branch collection tank 31 and the guide pipe 32 to the main collection tank 33. The fan 40 is started, and the airflow is heated by the heater 5 and then distributed to each branch pipe 2 through the main air pipe 1. The airflow is discharged from the opening and air outlet 20 at the end of the branch pipe 2, which quickly dries the vessels.

[0065] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
