With the rapid development of modern technology, some convenient smart homes are gradually entering our lives.Dry handiches are a very practical bathroom tool. Its biggest effect is to quickly dry hands, which changes the habit of scrubbing with paper towels after being washing hands.Now dry hand is more popular, and do you know what the working principle of dry handiches is?What should we pay attention to when we buy?Lets take a look at it!
What are the principles of dry hand?
1. The sensor detects the signal;
2. See the signal to control the heating circuit relay and hair dryer relay;
3. Start heating and blow air;
4. When the signal of the sensor detection disappears, release the contact, and the heating circuit and the hair dryer circuit relay is disconnected;
5. Stop heating and hair dryer.
What are the types of dry hand?
Heating is the main type:
Power size: large heating power, above 1000W, small motor power, less than 200W
Features: high wind temperature, slow drying
Advantages: small noise, suitable for the quiet space of writing buildings
Disadvantages: Slowly dry, usually above 30 seconds
High -speed wind type:
Power size: The heat power is relatively low, only a few hundred watts
Features: High wind speed, can reach more than 130 meters per second
Advantages: fast hand, usually within 10 seconds, suitable for food factories, pharmaceutical factories, electronic factories
Disadvantages: high price, suitable for factories and high -end places
Jet -type dry hand:
Power size: high -speed wind of up to 95 meters/s
Features: Energy -saving, hygiene, intelligent, safe, low noise, fast dry
Disadvantages: High price
How to choose a dry hand?
1. Heating time of Qi, so as to improve the heating efficiency of airflow at the nozzle.
2. Unique water disk design to prevent the ground from slipping
The attached unloadable water disk can greatly reduce the slippery situation of the ground in the toilet and reduce unnecessary accidents.There is also a full water instructions, clean and fast.
3. Beautiful appearance and more functions
4. Automatic infrared induction: Users do not need to contact any buttons, and the operation is simple and fast.
5. Full automatic dry hand motor:
You should also pay attention to which form of the electric motor used by the dry hand.
There are many forms for dried -handed motors, including capacitive asynchronous motors, hood -type motors, string motors, DC motors, and permanent magnet motors.Capacitor asynchronous motors, hood -type motor, and DC motor -driven dry hand has the advantages of low noise, while the string motor and the dry hand of the permanent magnet motor have the advantages of large air volume.With the above characteristics, small noise and large air volume have become the best choice for dry hand now.
6. The infrared induction of fully automatic dry hand:
When choosing an electromagnetic induction dry hand, you should pay attention to this dry handicapyticon being affected by the environment and items.Pay attention to selecting infrared induced dry -type dry hand. Infrared sensor -based dry handiches are also susceptible to light interference. Consumers need to conduct a test machine when buying, and select dry hand that is not vulnerable to interference.
7. The power consumption of fully automatic dry hand:
Now the dry hand that is fast and environmentally friendly and energy -saving is mainly wind -based, heating auxiliary dry hand.This kind of dry hand is characterized by high wind speed, which quickly blows off the water on the hand, and the heating function is only to maintain the comfort of the hand. Generally, the wind temperature is usually between 35-40 degrees.While fasting, there will be no burns.
8. Speed ??dry performance
Improve the wind speed and shorten the dry time! When the hot wind starts, about 5-9 seconds
Realize fast -drying, and the operating costs are greatly reduced
9. Cold and hot wind can be switched
Depending on the season, adjustable, due to the different seasons, you can switch the cool wind and hot air to reduce the annual operating fee.
10. Antibacterial treatment
Inhale air purification through super anti -allergic filters, more environmentally friendly and healthy!
11. Easy to clean, use antibacterial resin materials, easier to clean.
