Be careful when taking a bath in cold weather! The bathroom heater may turn into a "destroyer"

Take a hot bath in cold weather

It is undoubtedly a great way to relax

However

Common bathroom heaters

Hidden safety risks when using

If you don't pay attention

It may instantly become "Thanos"

What is going on?

Dr. Ke will take you to explore the scientific principles involved

As a common bathroom heating device, Yuba is usually divided into two types: light heating type and air heating type . But no matter which type, its internal circuit may age due to the continuous operation of the electric heating element during long-term operation.

In the humid environment of the bathroom, water vapor can easily penetrate into the circuit, causing the insulation performance to deteriorate, thus causing a short circuit or overload . In addition, some inferior bathroom heaters may not strictly follow national standards for quality control during the production process. Their circuit layout is chaotic, the parts are of poor quality, and they even lack necessary safety protection measures. For example, the light bulbs of the light-heating bathroom heaters are not equipped with explosion-proof functions , or some brands of bathroom heaters perform poorly in heat resistance tests, and their plastic parts are easily deformed at high temperatures, etc., which greatly increase the risk of fire and explosion.

(1)

Quality issues

In order to reduce costs, some inferior or low-quality bathroom heaters use low-quality raw materials and parts during the production process. These products are more likely to have problems such as short circuits and component damage in the hot and humid bathroom environment, which can cause fires or explosions.

(2)

Overage service

The service life of a bathroom heater is generally 5-8 years. After the service life, its internal circuits and components will age faster. The insulation layer of the aged circuit is easily damaged , resulting in current leakage; the performance of the components will also drop significantly, increasing the probability of failure.

(3)

Improper use

When using a bathroom heater, if water is sprayed directly onto the bulb or motor, especially cold water, the temperature difference will cause the bulb to burst or the motor to be damaged. In addition, if the water vapor concentration in the bathroom is too high, it will accelerate the aging of the circuit and accessories , and may even penetrate into the bathroom heater and cause a short circuit.

(1)

Buy regular products

When purchasing a bathroom heater, you should choose a well-known brand that has passed national quality certification, and ask a professional to install it to ensure that the line connection is correct and firm to avoid line overload or short circuit due to improper installation.

(2)

Regular inspection and maintenance

It is recommended to conduct a comprehensive inspection of the bathroom heater every six months , focusing on whether the insulation layer of the circuit is aging or damaged, whether the light bulb is loose or damaged, and whether the motor is running normally. If any abnormality is found, the relevant parts should be replaced in time. For bathroom heaters that have not been used for a long time , a comprehensive inspection should be carried out before using them again to ensure their safety and reliability.

(3)

Standard Use

When using a bathroom heater, avoid spraying water directly onto the bulb or motor, especially cold water , to prevent the bulb from bursting or the motor from being damaged due to sudden cooling. At the same time, the bathroom should be well ventilated to avoid excessive water vapor concentration. After use, turn off the power supply and unplug the plug in time to prevent the motor from getting damp, which will reduce the insulation performance of the electronic components and avoid possible fire or electric shock accidents.

In cold weather

Although the bathroom heater provides us with warmth

But its potential safety hazards cannot be ignored

Only scientific purchase and standardized use

And regularly maintain the bathroom heater

In order to enjoy the warmth

Keep yourself and your family safe!
