Description

Constant-temperature water outlet device with temperature display function

Technical Field

The utility model relates to a bathroom technical field, concretely relates to constant temperature goes out water installation with temperature display function.

Background

Conventional washbasin faucets or shower faucets, generally have a water mixing function. Mixing water is mixing cold water and hot water to obtain warm water. However, since the product sales region is very wide, the actual installation conditions of each product are different, and the water inlet temperature is also different, the hot water with the same temperature cannot be always obtained with the same cold-hot water ratio.

The market has a tap with temperature feedback and compensation functions, and the proportion of cold and hot water inlet can be automatically adjusted according to the temperature of outlet water, so that the basic stability of the temperature of the outlet water is realized. A problem with such faucets is that it is difficult to accurately mark the temperature of the exiting water due to the non-linearity and non-uniformity of the control mechanism.

In both of the above faucets, the user needs to adjust-feel-readjust-feel repeated at the time of use.

Therefore, a faucet is also available in the market, and the temperature of the discharged water can be displayed in real time. However, the faucet passively displays the temperature of the outlet water, and when the temperature of the inlet water changes, the proportion of cold water and hot water cannot be adjusted in real time, so that the temperature stability of the warm water cannot be guaranteed. In addition, the display usually lags behind the temperature setting action, which is inconvenient.

There is another faucet that uses a control panel to direct the operation of an actuator to adjust the water temperature in real time. The actuator is typically an electrically driven drive mechanism to adjust the mix ratio of hot and cold water. This system is good, but costly.

For this reason, how to conveniently control the faucet with a simple structure and at a lower cost is a problem that those skilled in the art have yet to solve.
