Description

Technical Field

[0001] This application relates to the field of dryer technology, and in particular to a dryer air outlet duct structure. Background Technology

[0002] Currently, hot air drum drying involves hot air flowing from the rear to the front, making full contact with the material and fully utilizing heat transfer through conduction, convection, and radiation. Heat energy is directly transferred to the material, causing the moisture to evaporate continuously within the drum. Dryer control is mainly divided into time control and humidity control. Time control operates according to a pre-set time; humidity control operates based on the humidity level inside the dryer. When the humidity inside the dryer reaches the preset level, the dryer stops working.

[0003] Related technology can be found in Chinese patent application CN219511143U, which discloses an intelligent humidity control device for a dryer. The device includes a feeding mechanism with a drying mechanism connected to its bottom. A stirring component is installed inside the drying mechanism, a drive component is connected to one side of the stirring component, a heating pipe is connected to one side of the drying mechanism, and a heating component is connected to the other side of the heating pipe. This dryer, by setting up an intelligent humidity detector and cooperating with a backend control system, can transmit humidity data back to the backend in real time. The drying time of the drying mechanism is adjusted based on humidity detection, effectively reducing energy consumption and production costs. By setting up the stirring component in conjunction with the drying tank, cleaned feathers and down can be quickly dried and spun dry. An industrial blower blows lighter feathers upwards while heavier ones automatically fall downwards, thus sorting out the good down material for the next step.

[0004] Regarding the aforementioned technologies, when the device dries and agitates feathers and down, some feathers and down come into contact with the intelligent humidity detector and adhere to its surface, thus affecting the intelligent humidity detector's ability to detect humidity inside the drying tank, resulting in low detection accuracy of the intelligent humidity detector. Utility Model Content

[0005] To improve the detection accuracy of humidity detectors, this application provides a dryer air outlet duct structure.

[0006] This application provides a dryer air outlet duct structure, which adopts the following technical solution: A dryer air outlet duct structure includes a dryer body, an air outlet on the lower end of the dryer body away from the inlet, a fan fixedly mounted on the lower end of the dryer body away from the inlet, the fan facing the air outlet, a guide channel fixedly mounted on the side of the dryer body near the fan, one end of the guide channel facing the air outlet, the fan located inside the guide channel, a support plate located inside the guide channel, a humidity detector located at the upper end of the guide channel, a protective component located at the lower end of the support plate, the humidity detector located inside the protective component, the protective component being used to prevent lint from contacting the humidity detector.

[0007] By adopting the above technical solution, the dryer body dries the clothes. During the operation of the dryer body, the fan draws the hot and humid air inside the dryer body out of the air outlet. The hot and humid air moves along the air guide channel and is then discharged. The support plate supports the humidity detector. The humidity detector detects the humidity of the hot and humid air in the air guide channel and thus determines the degree of drying of the clothes. The protective part helps to reduce the probability of lint adhering to the surface of the humidity detector and improves the accuracy of the humidity detector's detection results.

[0008] Optionally, the end of the air duct away from the air outlet extends upward to the upper part of the dryer body.

[0009] By adopting the above technical solution, the air guide channel is set vertically, which helps to reduce the probability of humidity concentration at the lower end of the dryer body, reduces the probability of clothes getting damp again, and improves drying efficiency.

[0010] Optionally, the protective component includes a ventilated cover located at the lower end of the support plate and detachably mounted therefrom, with a humidity detector located inside the ventilated cover.

[0011] By adopting the above technical solution, the breathable cover blocks lint, reducing the probability of lint coming into contact with the humidity detector and improving the accuracy of the humidity detector's detection results.

[0012] Optionally, a gap is left between the vent and the humidity sensor.

[0013] By adopting the above technical solution, when there is lint attached to the vent, there is still a gap between the humidity detector and the vent, and the humidity detector is not affected by the lint, which further improves the accuracy of the humidity detector's detection results.

[0014] Optionally, the hood is made of soft, breathable mesh fabric.

[0015] By adopting the above technical solution, when hot and humid air flows in the air guide channel, the ventilator shakes under the action of hot and humid air, which causes the lint on the surface of the ventilator to fall off, thus improving the convenience of cleaning the lint on the surface of the ventilator.

[0016] Optionally, a filter screen is fixed inside the air duct, located below the humidity detector.

[0017] By adopting the above technical solution, the filter screen blocks larger lint, allowing smaller lint to continue moving upward. This design provides sufficient space for the flow of hot and humid air, while reducing the area where lint adheres to the ventilator. This allows hot and humid air to have sufficient channels to flow into the ventilator, improving the accuracy of the humidity detector's results.

[0018] Optionally, an air source component is fixed on the outside of the air guide channel. An air pipe is connected to the side of the air source component that is close to the air guide channel. The side of the air pipe that is away from the air source component is located inside the air guide tube and is directly opposite the upper end of the filter screen.

[0019] By adopting the above technical solution, when the dryer body finishes drying, the air source component and air pipe work together to blow air onto the filter screen, blowing off the lint on the filter screen and improving the convenience of cleaning the filter screen.

[0020] Optionally, a collection chamber is connected to the lower end of the air guide channel on the side away from the fan. The collection chamber and the air guide channel are detachable, and the collection chamber is located directly below the filter screen.

[0021] By adopting the above technical solution, the collection chamber is used to collect the lint that falls off the filter screen. When the lint on the filter screen is cleaned, the operator separates the collection chamber from the air guide channel and then cleans the collection chamber, which helps to reduce the probability of lint being blown up during the operation of the dryer.

[0022] Optionally, a movable opening is provided on the side of the upper end of the air guide channel away from the dryer body. A movable plate is provided in the movable opening. The movable plate is slidably connected to the air guide channel in the transverse direction and is interference-fitted with the air guide channel. A support plate is fixedly connected to the side of the movable plate close to the dryer body. A handle is fixedly provided on the side of the movable plate away from the support plate.

[0023] By adopting the above technical solution, when the humidity detector malfunctions, the operator can grasp the handle and separate the moving plate from the moving port, thereby removing the support plate and humidity detector from the air duct. The operator can then replace and inspect the humidity detector, which improves the convenience of humidity detector maintenance and replacement.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The fan draws hot and humid air from the dryer body through the air outlet. The hot and humid air moves along the air guide channel and is then discharged. The air guide channel is set vertically, which helps to reduce the probability of the clothes getting damp again due to the concentration of humidity at the lower end of the dryer body. The humidity detector detects the humidity of the hot and humid air in the air guide channel and then judges the degree of drying of the clothes. The protective part helps to reduce the probability of lint adhering to the surface of the humidity detector and improves the accuracy of the humidity detector's detection results. 2. When hot and humid air flows in the air guide channel, the ventilator shakes under the action of the hot and humid air, which causes the lint on the surface of the ventilator to fall off, thus improving the convenience of cleaning the lint on the surface of the ventilator. 3. When the humidity detector malfunctions or the vent cover is heavily covered with lint, the operator can grip the handle to move the moving plate and support plate, thereby removing the humidity detector from the air duct. The operator can then remove the vent cover from the support plate and clean it before inspecting and repairing the humidity detector, thus improving the convenience of humidity detector maintenance and replacement.

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a dryer air outlet duct structure. Example

[0033] Reference Figure 1 and Figure 2A dryer air outlet structure includes a dryer body 1, an air outlet 11 is opened on the lower end of the dryer body 1 away from the inlet, and a fan 12 is fixed on the lower end of the dryer body 1 away from the inlet. The fan 12 is directly opposite the air outlet 11. When the dryer body 1 dries clothes, the fan 12 draws the hot and humid air in the dryer body 1 out from the air outlet 11.

[0034] Reference Figure 1 and Figure 2 A guide channel 2 is fixed on the side of the dryer body 1 near the fan 12. One end of the guide channel 2 is directly opposite the air outlet 11. The fan 12 is located inside the guide channel 2. The end of the guide channel 2 away from the air outlet 11 extends upward to the upper part of the dryer body 1. Hot and humid air moves along the guide channel 2 and is then discharged. The guide channel 2 is set vertically, which helps to reduce the probability of the clothes getting damp again due to the concentration of humidity at the lower part of the dryer body 1, and improves the drying efficiency.

[0035] Reference Figure 3 and Figure 4 A support plate 21 is provided inside the air guide channel 2. The support plate 21 is located at the upper end of the air guide channel 2. A humidity detector 22 is provided at the lower end of the support plate 21. The support plate 21 provides fixed support for the humidity detector 22. The humidity detector 22 detects the humidity of the hot and humid air inside the air guide channel 2, thereby determining the degree of drying of the clothes.

[0036] Reference Figure 3 and Figure 4 The lower end of the support plate 21 is provided with a protective component 3, and the humidity detector 22 is located inside the protective component 3. The protective component 3 is used to prevent the lint from contacting the humidity detector 22, thereby improving the accuracy of the detection results of the humidity detector 22.

[0037] Reference Figure 3 and Figure 4 The protective component 3 includes a breathable cover 31, which is located at the lower end of the support plate 21 and is detachably mounted to the support plate 21. The humidity detector 22 is located inside the breathable cover 31. The breathable cover 31 blocks the lint, reducing the probability of the lint coming into contact with the humidity detector 22 and improving the accuracy of the detection results of the humidity detector 22.

[0038] Reference Figure 4A gap exists between the ventilation cover 31 and the humidity detector 22. Even when lint adheres to the ventilation cover 31, there is still sufficient space between them, preventing the humidity detector 22 from being affected by the lint and further improving the accuracy of its detection results. The ventilation cover 31 is made of soft, breathable mesh fabric. When hot and humid air flows through the air guide channel 2, the ventilation cover 31 shakes under the influence of the hot and humid air, causing the lint on its surface to fall off, thus improving the ease of cleaning the lint from the surface of the ventilation cover 31.

[0039] Reference Figure 3 A filter screen 23 is fixed inside the air guide channel 2. The filter screen 23 is "M" shaped and is located below the humidity detector 22. The filter screen 23 blocks larger lint and allows smaller lint to continue to move upward. This setting allows hot and humid air to flow into the ventilation cover 31 through sufficient channels, improving the accuracy of the detection results of the humidity detector 22.

[0040] Reference Figure 1 and Figure 3 An air source component 4 is fixedly installed on the outside of the air guide channel 2. An air pipe 41 is connected to the side of the air source component 4 near the air guide channel 2. The side of the air pipe 41 away from the air source component 4 is located inside the air guide and is directly opposite the upper end of the filter screen 23. When the dryer body 1 finishes drying, the air source component 4 and the air pipe 41 work together to blow air onto the filter screen 23 to blow off the lint on the filter screen 23.

[0041] Reference Figure 1 and Figure 3 The lower end of the air guide channel 2, away from the fan 12, is connected to a collection chamber 27. The collection chamber 27 is detachably connected to the air guide channel 2. The collection chamber 27 is located directly below the filter screen 23. The collection chamber 27 is used to collect the lint that falls on the filter screen 23. When the lint on the filter screen 23 is cleaned, the operator separates the collection chamber 27 from the air guide channel 2 and then cleans the collection chamber 27. This helps to reduce the probability of lint being blown up during the operation of the dryer body 1.

[0042] Reference Figure 1 and Figure 5A movable opening 24 is opened on the upper end of the air guide channel 2 away from the dryer body 1. A movable plate 25 is provided in the movable opening 24. The movable plate 25 is slidably connected to the air guide channel 2 in the transverse direction and is interference-fitted with the air guide channel 2. A support plate 21 is fixedly connected to the movable plate 25 on the side close to the dryer body 1. A handle 26 is fixed on the side of the movable plate 25 away from the support plate 21. When the humidity detector 22 malfunctions or the lint on the vent 31 is seriously attached, the operator holds the handle 26 to move the movable plate 25 and the support plate 21 to remove the humidity detector 22 from the air guide channel 2. The operator removes the vent 31 from the support plate 21 and cleans and replaces it. This improves the convenience of the humidity detector 22's maintenance and replacement.

[0043] The implementation principle of the air outlet duct structure of the dryer in this embodiment is as follows: the fan 12 draws out the hot and humid air from the dryer body 1. The hot and humid air moves in the air guide channel 2. The filter screen 23 blocks larger lint, while smaller lint adheres to the ventilation cover 31. The humidity detector 22 detects the humidity of the hot and humid air in the air guide channel 2 to determine the degree of drying of the clothes. When there is a lot of lint on the ventilation cover 31, the hot and humid air causes the ventilation cover 31 to shake, which causes the lint on the surface of the ventilation cover 31 to fall off, allowing the hot and humid air to have enough space to enter the interior of the ventilation cover 31. The ventilation cover 31 protects the humidity detector 22, which helps to reduce the probability of lint adhering to the surface of the humidity detector 22. When the dryer body 1 finishes drying, the air source 4 and the air pipe 41 work together to blow air onto the filter screen 23, blowing off the lint on the filter screen 23 and causing it to fall into the collection chamber 27, thus improving the accuracy of the detection results of the humidity detector 22.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
