Description

Exhaust type anti-cracking instant heating device Technical Field The utility model relates to the technical field of instant heating devices, in particular to an exhaust type anti-cracking instant heating device. Background The instant heating device of the intelligent closestool is a core component for realizing instant hot water flushing. Through the rapid heating of the water flow, the user can immediately obtain hot water with proper temperature when using the water flow, so that the use experience is improved and the energy efficiency is improved. The instant heating device mainly comprises a heating element, a water flow sensor, a temperature sensor, a control unit and a water flow pipeline. When the user activates the flushing function, the water flow sensor detects a water flow signal and the control unit then activates the heating element. The water flow is heated rapidly when passing through the heating element, and the temperature sensor monitors the water temperature in real time and feeds the data back to the control unit. The control unit automatically adjusts the heating power according to the set temperature target to ensure that the water temperature is kept constant. However, freezing of water may occur in a low temperature environment such as a cold region or country, i.e., in the water flow conduit of the thermal device. This creates a large pressure inside the pipe as the water expands in volume as it freezes. If these pressures are not released in time, the water flow conduit may be broken or damaged by being subjected to excessive stress. The problem not only can influence the normal use of the intelligent closestool, but also can cause equipment failure and increase maintenance cost.
