Driven by higher living standards, more households have chosen smart toilets. Compared with conventional toilets, smart toilets’ advantages are quite attractive to customers, such as being environment-friendly, water efficient, enhanced hygiene, and better user experience.
Smart toilets are an innovative technology, such as NTC thermistors for temperature control, that is widely used in commercial and residential settings.
1. Development of smart toilets:
The global smart toilet seat market was approximately US$3,919.8 million in 2022 and is expected to reach US$3,512.3 million in 2029, with a compound annual growth rate (CAGR) of 1.6% from 2023 to 2029.
The top four global smart toilet seat manufacturers account for over 25% of the market share.
Currently, China is the world’s largest smart toilet seat market, accounting for about 50% of the market share. The United States and Europe follow, accounting for more than 20% of the market share.
2. Smart toilet’s structure
Smart toilets are mainly composed of the toilet body, heated seat ring, seat cover, cleaning system, and water temperature control system.
3. Principle of multifunctional smart toilets
The smart toilet is a high-tech bathroom product that integrates multiple intelligent functions. Its main functions include warm water cleaning, seat heating, air drying, etc.
NTC thermistors are widely applied in smart toilets’ heating, for example:
3.1Heated seat:
Toilet seat heating includes seat upper mold, seat lower mold, and heating assembly. An NTC thermistor is used to detect temperature changes in the heating film. At the same time, real-time monitoring of seat temperature and adjusting the temperature difference according to the ambient temperature can ensure that the seat temperature is constant within the set comfortable temperature range. A heated seat can help loosen tense muscles for those with trouble relaxing on the toilet.
3.2Warm water flushing:
Smart toilets are generally equipped with nozzles for butt cleaning. The human body’s comfortable acceptance of water temperature is 37-40℃, but daily cold water is 20~30℃. For a better user experience, smart toilets must keep the water temperature constant to the human comfort temperature. The toilet water heater has a built-in heating element. The NTC thermistor detects the water flow temperature in real time and feeds the temperature data to the heating system to set the temperature within the comfort range. It will not be overheated or overcooled and can provide users with a comfortable flushing experience.
3.3Warm air drying:
The warm air drying duct has a built-in heating wire, and the NTC thermistor mainly monitors the ambient temperature of the air outlet and adjusts the heating control system in real-time. Ensure that the warm air temperature is moderate so that it can dry quickly and maintain a constant temperature in real time without causing discomfort to the user.
4. Conclusion
Smart toilets are more intelligent, user-friendly, and Internet-based; they provide users with a more comfortable and convenient experience. They can be adjusted to meet the hygiene and health needs of different people. NTC thermistor plays an important role in smart toilets. Real-time monitoring and controlling the temperature ensures that multiple functions, such as seat heating, warm water flushing, and warm air drying, operate normally and safely, allowing users to experience more relaxation and luxury.
