Disclosure of Invention
The invention aims to solve the technical problem of providing an auxiliary heater of a central air conditioner, which can avoid dry burning and timely detect and control the overheating problem of a heating pipe so as to improve the safety.
In order to solve the technical problem, the auxiliary heater of the central air conditioner comprises a vertically arranged barrel, a heating pipe arranged in the barrel, a water inlet close to the bottom of the barrel and a water outlet close to the top of the barrel, wherein the water inlet and the water outlet are arranged on the side wall of the barrel, the heating pipe vertically extends into an inner cavity of the barrel from the bottom of the barrel, the heating end of the heating pipe is fixedly arranged at the bottom of the barrel, a pressure release valve mounting opening is formed in the top of the barrel, a temperature sensing device arranged beside the pressure release valve mounting opening is further arranged at the top of the barrel, and the heating pipe can be stopped heating by detecting the temperature sensing device based on the detected temperature.
The temperature sensing device comprises a pipe body and a temperature sensing head arranged in the pipe body.
A reed which is pressed on the temperature sensing probe is also arranged in the tube body.
The pipe body is made of metal materials.
The pressure relief valve mounting port is provided with a mounting end with a flange, and the temperature sensing device is pressed against the mounting end.
And a junction box is arranged at the bottom of the barrel.
And the barrel is provided with a mounting bracket positioned on the opposite side of the water inlet and the water outlet.
After the structure is adopted, the water level line can be positioned above the tail ends of all the heating pipes, the real temperature of the water temperature in the cylinder body can be obtained in time by utilizing the detection of the temperature sensing device, if the temperature rises rapidly due to overhigh temperature or water shortage, the heater can be stopped heating in time, so that the tail end heating pipe is prevented from being exposed in the air, the heating pipe is dried to burn, the heating pipe is damaged, and even safety accidents such as explosion and the like exist; in addition, a reed which is pressed on the temperature sensing probe is arranged in the pipe body, and the temperature detection effect is further improved through the designed reed.
