Rapid small water heater

Abstract

The invention provides a rapid small water heater of the structural style. The rapid small water heater is simple in structure, ingenious in design and reasonable in layout. The structural device which can automatically regulate the heating amount is designed for the defects that a traditional rapid heating type water heater is low in water temperature when water flow is large, and water is prone to boiling when the water flow is small, and therefore the water temperature of the water heater can be more stable. The repulsive force between magnets is creatively utilized, whether an additional resistor is connected into a working circuit in parallel or not is determined according to the size of the water flow, the value of the overall resistance in the working circuit is controlled according to the additional resistor, and therefore the heating amount of a working resistor is changed, the relatively-low-temperature heating can be achieved when the water flow is small, the relatively-high-temperature heating can be achieved when the water flow is large, and warm water or hot water can be provided for users under all water flow conditions. Thus, it can be said that the rapid small water heater has various advantages, is particularly suitable for application and popularization in the field, and is quite wide in market prospect.

Description

technical field [0001] The invention relates to a water heater, in particular to a small instant water heater. Background technique [0002] The temperature of the water coming out of the quick-heating faucets currently on the market depends on the time it takes for the water body to flow through the entire device of the water heater. The longer the time, the higher the water temperature. Therefore, once the water consumption is less and the flow rate is slower, the water body may boil in the water heater, causing various unsafe factors and affecting the life of the water heater. In order to avoid the above problems, in the design of the traditional instant water heater, its power will be reduced as much as possible to protect the safety of the water heater under the small water flow, but at the same time, this will cause the water temperature to be too low when the water flow is large, which cannot meet people's expectations of the water temperature of the water heater. us...

Therefore, once the water consumption is small and the flow rate is slow, the water body may boil in the water heater, causing various unsafe factors and affecting the life of the water heater.

In order to avoid the above problems, in the design of the traditional instant water heater, its power will be reduced as much as possible to protect the safety of the water heater under the small water flow, but at the same time, this will cause the water temperature to be too low when the water flow is large, which cannot meet people's expectations of the water temperature of the water heater. requirements for use
