Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hand dryers, and particularly relates to a hand dryer and an innovative method capable of recycling water resources and achieving automatic lifting adjustment. BACKGROUND

[0002] Hand dryers have been widely used in public places such as shopping malls, airports, office buildings and public washrooms, providing a very convenient hand drying service for the public.

[0003] Hand dryers with double-sided blowing structure are favored due to their high-efficiency blowing effect. This design can quickly blow away the water on the hands. Usually, the hand dryer is installed on one side of the washbasin. This layout reduces the moving distance of the user and also makes the overall environment look more coordinated and beautiful.

[0004] However, we have also noticed some inconveniences in use. The height of the washbasin is usually between 70-80 cm, which means that for adults taller than 1.6 meters, they need to slightly bend over to aim their hands at the air outlet of the hand dryer when using it. In addition, the two strong airflows generated by the hand dryer will be thrown upwards after blowing away the water on the hands, directly blowing onto the user's face, causing discomfort. In order to avoid this airflow, the user often needs to turn his face sideways or adopt other awkward postures, which undoubtedly affects the use experience. This design obviously does not fully consider the use needs of users of different heights, especially causing great inconvenience to users with a higher body.

[0005] On the other hand, during the process of blowing the hands, the hand dryer will discharge the water along with the high-speed airflow from the bottom drain, and these water droplets are collected in the water collection pool at the bottom of the hand dryer. As described in Chinese invention patent application (publication number: CN106028893 A), when the water tray for collecting water droplets falling from the user's hands is full, the hand dryer needs to be notified to stop running, detect faults, and take corresponding measures to restore normal operation. This process involves a lot of cleaning and maintenance work, which undoubtedly increases the operating cost.

[0006] In addition, it is worth noting that these discharged water resources are directly wasted and not effectively utilized.

[0007] Moreover, at the beginning of the working cycle of the hand dryer, the resistor can not be fully heated, and the temperature of the air discharged is relatively low. However, as the resistor continues to work, its temperature gradually rises, and without effective cooling measures or motor failure, the risk of fire can increase. In addition, the heating resistor may absorb dust around it during use, and the high-speed airflow may deposit these dusts on the resistor, hindering the normal heat dissipation of the resistor and causing the temperature of the resistor to rise abnormally. These accumulated dusts, due to their flammability, can exacerbate the risk of fire.

[0008] Therefore, there is an urgent need to develop an innovative hand dryer technical solution to address these problems. This new solution should have the ability to recycle and utilize the discharged moisture to reduce water waste; at the same time, it should be able to reduce the amount of maintenance and cleaning work by automatically adjusting the height of the hand dryer to meet the needs of users of different heights. Through the implementation of this design innovation, we aim to overcome the multiple defects of traditional hand dryers and greatly improve the user experience. SUMMARY

[0009] Therefore, the present application provides a method for recycling water resources and automatically lifting a hand dryer, and a hand dryer. The method automatically adjusts the lifting height of the hand dryer by intelligent sensing and detecting the height of the hand, reduces dust accumulation and improves heat transfer efficiency by using a flexible metal hose design, and can also recycle the water discharged during the drying process, achieving an innovative hand dryer system that saves water resources, reduces maintenance, and improves user experience.

After the position of the hand dryer air outlet matches the height of the user's hand, the user's hand is dried, and the water discharged during the drying process is collected; S4. The discharged water collected in step 3 is transported to the filtration circulation system for filtration treatment; S5. The filtered water is transported to the liquid storage tank; S6. A certain amount of filtered water is taken out from the liquid storage tank and heated or temperature-controlled to obtain hot water or cold water required by the lifting system; S7. The heated or temperature-controlled hot water or cold water is transported to the liquid reaction cavity of the memory alloy lifting mechanism, driving the memory alloy to change phase and deform, and then driving the mechanism to lift; S8. Repeat steps 1-7 to realize automatic lifting adjustment and water resource recycling of the hand dryer. The method can realize automatic lifting adjustment of the hand dryer, match the use height of different users, and recycle the discharged water resources, saving water resources and improving user experience.

[0037] The following will be combined with all the drawings Figures 1-5 The embodiments of the present application will be described in detail.

[0038] In the following, certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are considered to be exemplary in nature rather than limiting.

[0039] Embodiment 1, the invention provides a method for recycling water resources and automatic lifting of a hand dryer 01, which can effectively solve the problems of wasting water resources, large maintenance workload, inability to automatically adjust height, and dust accumulation on the resistor 03 of the traditional hand dryer 01. The specific implementation includes:

[0040] 1. Detect and record the height of the user's hand

[0041] Through the intelligent sensing system 02 installed above the hand dryer 01, the height data of the user's outstretched hand and the ground is detected and recorded. The intelligent sensing system 02 adopts a multi-sensor fusion technology, combining infrared sensors, ultrasonic range finders, and depth cameras, and other existing technologies, thereby greatly improving the accuracy of hand detection.

[0042] Further, the algorithm built-in the intelligent sensing system 02 can accurately identify the contour and position of the hand through machine learning training, effectively excluding false detection of other objects. The algorithm first preprocesses the captured infrared and depth images, extracts key features, and then inputs these features into a deep neural network model trained with a large amount of data. The model outputs the position coordinates of the hand and a confidence score. Only when the score is higher than the preset threshold, the system will confirm it as a valid hand and record its height data from the ground.

[0043] Further, the intelligent sensing system 02 also has an automatic background update function, which can adaptively adjust algorithm parameters according to environmental changes, thereby maintaining high detection accuracy in different scenarios. The application of this system is not only reliable and stable, but also fast in detection response, capable of tracking the motion trajectory of the user's hand in real time, laying the foundation for subsequent automatic lifting of the hand dryer.

[0044] 2. Control the automatic lifting of the hand dryer 01 according to the height of the hand

[0045] According to the height data of the hand obtained in step 1, the system calculates the height of the hand dryer 01 outlet that best matches the user's hand, and controls the built-in memory alloy lifting mechanism to drive the hand dryer 01 body to rise and fall to the adaptive height. In order to improve the maintainability and future upgrade and expansion capability of the system, the entire lifting control module adopts a modular standardized design concept. The memory alloy lifting mechanism, sensors, controllers and other core components all follow unified technical standards and interface specifications, ensuring the universal interchangeability between modules, and future upgrades and maintenance can be completed by simply replacing the corresponding components.

[0046] Further, the memory alloy lifting mechanism adopts a copper-based composite memory alloy with excellent performance as the driving part. Compared with single alloy, this composite material not only has higher shape memory recovery strain and wider deformation temperature range, but also significantly improves mechanical strength and corrosion resistance, greatly prolonging the service life.

[0047] Further, the liquid reaction cavity of the mechanism adopts a special double-layer micro-channel structure design, the contact area of the liquid channel with the memory alloy rod is maximized, so that the heat can be quickly transferred, thereby significantly shortening the time required for phase change. At the same time, high-efficiency thermoelectric semiconductor refrigeration chips are embedded in the inner wall of the cavity, which can quickly heat or cool the fluid according to the demand, greatly improving the response speed and controllability of the entire driving system.

[0048] In addition, the lifting mechanism also integrates a displacement sensor, which can monitor the displacement change of the memory alloy rod in real time and accurately adjust it through a closed-loop control system to ensure that the hand dryer body can be accurately positioned at the desired height position. The feedback control system contains advanced fuzzy logic algorithm, which can adaptively suppress the influence of various disturbance factors, thereby greatly improving the stability and reliability of the outlet height.

[0049] When the hand dryer 01 needs to be raised, the control system injects high-temperature liquid (such as hot water) into the sealed cavity where the memory alloy rod is located, so that the memory alloy rod is heated to above its deformation temperature and restores to a longer austenite shape, pushing the mechanism to rise. When the hand dryer 01 needs to be lowered, low-temperature liquid (such as cold water) is injected, so that the memory alloy rod cools below its deformation temperature and deforms to shorten, thereby driving the mechanism to descend.

[0050] In addition, in order to further improve the heating efficiency and overall performance of the system, the invention adopts an innovative flexible metal hose 04 design on the outer surface of the heating resistor wire of the resistor 03. The flexible metal hose 04 adopts stainless steel material with good thermal conductivity, and the inner surface is treated by special process to form micron-level porous hydrophobic coating, which helps to further improve the heat transfer efficiency.

[0051] Two flange joints are arranged on the hose, one end of which is communicated with the hot water pipeline of the circulating water system as the liquid inlet 05, and the other end is connected with the drain pipeline as the liquid outlet 06. When the hand dryer is started initially, the high-temperature hot water kept at a constant temperature first flows through the outer surface of the resistance wire at a high speed through the liquid inlet 05 of the hose, and with the good heat conduction performance of the metal hose and the capillary action of the micron-pore hydrophobic coating, the heat can be quickly and uniformly transmitted to the heating resistance wire, greatly shortening the heating process. The heated hot water is finally introduced into the liquid reaction cavity of the memory alloy lifting mechanism. It should be pointed out that since the operation of the resistance wire is synchronized with the circulating water system, the heating source in the circulating water system can be replaced by the resistance wire.

[0052] At the same time, when the flexible metal hose 04 is heated and expanded, the pore structure on the inner and outer walls will automatically expand and adjust the deformation amount, so that the hose body produces periodic expansion and contraction movement. This unique deformation characteristic makes it difficult for dust and dirt on the surface of the outer wall of the hose to be firmly adsorbed, thereby reducing the accumulation of dirt from the root. Combined with the self-flushing action of the flowing water, the outer surface of the resistor 03 can be kept clean for a long time, without frequent disassembly and maintenance, greatly reducing the daily operating cost.

[0053] The innovative design not only takes advantage of the rapid heat transfer, significantly improves the preheating and working efficiency of the hand dryer, but also solves the problem of dust accumulation affecting the service life in the conventional heating system, and has the characteristics of energy saving and environmental protection, which is another highlight technology of the application.

[0054] 3. The hand dryer 01 blows the hands

[0055] When the height of the hand dryer 01 air outlet matches the height of the user's hands, the user can stretch his hands into the air outlet, and the hand dryer 01 starts blowing the hands, blows away the residual water on the hands and discharges it from the bottom.

[0056] 4. Collect and filter the discharged water

[0057] A water collecting device is arranged at the bottom of the hand dryer 01 for collecting the discharged water resources during the blowing process. The discharged water resources are transported to the high-efficiency filtering circulating system which adopts a double filtering system, first passes through the coarse filtering device to preliminarily filter out larger particles of pollutants and impurities, and then passes through the fine filtering device for deep filtration to remove fine suspended matter and dissolved substances in the water. The double filtering design of first coarse and then fine not only improves the overall filtering efficiency, but also effectively prolongs the service life of the filtering medium at each level, reducing the maintenance cost.

[0058] Furthermore, the filtration and circulation system also integrates an advanced online water quality monitoring module, which can detect key indicators such as turbidity, pH value, and conductivity of the filtered water in real time. Once an abnormality is detected, the system will automatically switch to direct drainage mode to prevent turbid water from entering subsequent stages and affecting the recycling effect.

[0059] Furthermore, in order to improve the energy efficiency of water resource recycling, the system adopts a low-energy continuously variable submersible pump that automatically adjusts the flow rate according to real-time water demand, effectively reducing energy consumption.

[0060] In addition, the system is equipped with a water tank heating device, which can keep the stored circulating water warm or heated according to the ambient temperature, preventing freezing and crystallization in low-temperature environments from affecting normal circulation. This heating device adopts a reliable semiconductor cooling chip reverse operation principle, which has the advantages of fast heating speed, high efficiency, and no noise.

[0061] 5. Transfer the filtered water to the storage tank 21

[0062] The filtered purified water is transported through pipelines to the storage tank 21 in the hot and cold liquid supply module of the shape memory alloy lifting mechanism for use in the next step.

[0063] 6. Heating or temperature control supply to the lifting system

[0064] The control system takes out a certain amount of filtered water from the storage tank 21 as needed, and heats or controls the water through a heating device or a constant temperature device to obtain hot or cold water that meets the requirements of the shape memory alloy drive.

[0065] 7. Drive memory alloy lifting mechanism

[0066] Heated or temperature-controlled water is delivered to the liquid reaction chamber of the shape memory alloy lifting mechanism, driving the shape memory alloy to undergo phase change and deformation, which in turn drives the mechanism to produce lifting motion, causing the hand dryer 01 body to move up and down.

[0067] 8. Repeat the above steps.

[0068] The above steps are repeated cyclically, continuously detecting the height of the new user's hand and adjusting the height of the hand dryer 01 accordingly. The discharged water is recycled through the circulating water system to achieve the purpose of saving water resources and automatic lifting.

[0069] This method enables the hand dryer 01 to automatically adjust its height to suit different users while recycling its own discharged water, avoiding direct water waste. It also reduces the cleaning and maintenance of the water tank, improving both the environmental friendliness and user experience of the hand dryer 01. Furthermore, by wrapping a flexible hose around the resistance wire of resistor 03, the heating speed is effectively increased and dust accumulation on resistor 03 is reduced, further enhancing the system's efficiency and performance. This method combines the advantages of energy saving, environmental protection, and user-friendly design, representing a powerful supplement and iteration to traditional hand dryer technology.
