Multifunctional NTC Thermistor for Smart Toilet

Driven by higher living standards, smart toilets have been chosen by more households. Compared with conventional toilets, smart toilets’ advantages are quite attractive to customers: such as environment friendly, water efficiency, enhanced hygiene, better user experience, etc

As innovative technology helps, such as NTC thermistors for temperature control, smart toilets are widespread in commercial and residential.

1.Development of smart toilets:

The global smart toilet seat market size is 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% during 2023-2029.

The top four global smart toilet seat manufacturers account for more than 25% of the market share.

Currently, China is the world‘s largest smart toilet seat market, accounting for about 50% of the market share, followed by the United States and Europe, which together account 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, water temperature control system, etc.

3.Principle of multifunctionalsmart toilets

The smart toilet is a high-tech bathroom product that integrates multiple intelligent functions. Its main functions include: warm water cleaning, seat heating, warm air drying, etc.

NTC thermistors are widely applied smart toilets’ heating, for example:

3.1Heated seat:

Toilet seat heating includes seat upper mold, seat lower mold and heating assembly. NTC thermistor is used to detectthe temperature change of heating film. At the same time, by real-time monitoring of seat temperature and adjusting the temperature difference according to the ambient temperature, it can ensure that the seat temperature is constant within the set comfortable temperature range. Having a heated seat can help loosen tense muscles for those who may have 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 better user experience, smart toilets need to 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 back the temperature data to the heating system to set the water 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 thermistormainly monitors the ambient temperature of the air outlet and adjusts the heating control system in real time. Ensuring that the warm air temperature is moderate can not only dry quickly, but also 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 according meet the hygiene and health needs of different groups of people. NTC thermistor plays an important role for smart toilets. By real-time monitoring and controlling the temperature, it ensures that multiple functions such as seat heating, warm water flushing, and warm air drying operate normally and safely, allowing users to experience more relaxed and luxurious.
