small instant water heater

Abstract

The small instant water heater with the structural form of the present invention has the advantages of simple structure, ingenious design and reasonable layout. Aiming at the defects of traditional instant water heaters that the water temperature is low when the water flow is large, and the water body is easy to boil when the water flow is small, it designs a structural device that can automatically adjust the calorific value, making the water temperature of the water heater more stable. It creatively uses the repulsion between the magnets, and decides whether to connect an additional resistor in parallel in the working circuit according to the size of the water flow, and controls the overall resistance value in the working circuit through the additional resistor, thereby changing the calorific value of the working resistor, which can realize It heats at a relatively low temperature when there is a small water flow, and heats at a relatively high temperature when there is a large water flow. No matter what the water flow is, it can provide users with warm or hot water. Therefore it can be said that it has possessed multiple advantages, and is particularly suitable for popularization and application in this field, and its market prospect is very broad.

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
