1. What is a Direct Hot and Cold Dispenser?
A direct hot and cold dispenser is a compact household appliance designed to heat water directly upon activation, eliminating the need for a water storage tank.
Equipped with various safety sensors like water flow sensor, ELCB shock-proof switch, temperature sensors, the dispenser ensures safe usage.
2. Structure and Operation Principles of Direct Hot and Cold Dispensers
Common Structure
Direct hot and cold showers are constructed with parts such as: machine casing, power cord, heating element (responsible for heating water), valve, and more. Especially, direct hot water machines are equipped with a temperature sensor that automatically shuts off when the temperature exceeds the allowed threshold.
Working Principle
Direct hot and cold showers operate based on the mechanism of heating water using an electric resistor. Specifically, the heating element is tasked with increasing the water temperature inside the device using the electric resistor. After the water is heated, it is directed to the nozzle directly, providing instant use.
3. Pros and Cons of Direct Hot and Cold Showers
Advantages
- Direct hot and cold machines heat water almost instantly due to the direct heating mechanism using an electric resistor. Therefore, you don't have to wait and can immediately use warm water in the freezing winter.
- The device boasts a fairly compact size, saving space for interior design, ideal for families with limited bathroom space.
- Installation of the machine is simple and easy.
- The machine is equipped with various safety mechanisms such as the ELCB anti-electric shock device, temperature sensor, and water flow sensor. In case of a current leakage, the anti-electric shock device will operate by creating a difference in the currents passing through and will automatically cut off the circuit. This ensures safety for users, preventing electric shock.
- The machine comes in a variety of models, styles, and brands for users to choose from comfortably.
Disadvantages
Apart from the advantages, direct hot and cold showers also have some drawbacks:
- Heating water every time it's used consumes a lot of electricity, making the machine unsuitable for large families.
- The machine operates inefficiently in places with low water pressure, weak power sources, and instability.
4. Common types of direct hot and cold showers nowadays
Direct hot and cold shower with booster pump
Direct hot and cold showers with booster pumps are equipped with automatic ELCB anti-shock circuit breakers, ensuring safety during use. The machine's booster pump increases water pressure, delivering a strong and stable hot water supply.
Direct hot and cold shower without booster pump
- The machine is compact in size as it doesn't have an additional booster pump, suitable for small bathroom spaces. However, it may not meet the hot water demand when installed in areas with weak and unstable water sources.
Direct hot and cold shower with heating rods, resistors
The device has a compact design and heats up quickly. However, the heating rods inside the machine, when used for a long time, may accumulate dirt, causing a sudden increase in temperature, leading to electrical leakage and safety risks.
Infrared direct hot and cold shower
This type of machine is integrated with many smart features, so it has a relatively high price. The machine has a Nano Carbon-coated heating element that enhances durability and corrosion resistance.
It's not difficult to find a direct hot and cold shower on the market with a variety of designs, functions, and prices. However, to ensure you purchase genuine, quality products with good prices and many benefits, consider visiting large electronics retailers such as Mytour.
