Problems solved by technology

In the related art, the air conditioner is usually equipped with a PTC (Positive Temperature Coefficient, positive temperature coefficient) type electric heating tube, and a thermostat and a fuse are arranged outside the electric heating tube. In such an abnormal situation, the electric heating tube will reduce the power of the electric heating tube and the temperature around the electric heating tube due to the positive temperature coefficient of the PTC inside it, and then the operating temperature of the thermostat and the fuse cannot be reached. It cannot protect the electric heating tube, so that the electric heating tube is always in a state of dry burning until it is discovered by humans. Therefore, there is a greater risk in the use of air conditioners

Abstract

The invention provides an electric heating pipe and an air conditioner. The electric heating pipe is used for the air conditioner and comprises a shell, a heating piece assembly and a temperature controller. The heating piece assembly is arranged in the shell and comprises a PTC piece and an NTC piece. The temperature controller is arranged on the outer wall of the shell and is close to the NTC piece. According to the electric heating pipe and the air conditioner, the temperature controller is arranged on the outer wall of the shell and is close to the NTC piece, when the electric heating pipe is under abnormal working conditions such as dryout, the power of the NTC piece is increased fast, the NTC surrounding temperature is fast increased, then the action temperature of the temperature controller is achieved, the function of fast protecting the electric heating pipe is achieved, and the situation that the air conditioner breaks down and is even damaged due to the abnormal working conditions of the electric heating pipe is avoided; and furthermore, the temperature controller is close to the NTC piece, the temperature controller can be in contact with high-temperature air flow generated by the electric heating pipe in abnormal working fast, then the action speed of the temperature controller is increased, and operating reliability and safety of the air conditioner are guaranteed.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an electric heating tube and an air conditioner. Background technique [0002] Nowadays, air conditioners are accepted by more and more families because of their advantages such as simple operation and good cooling / heating effect. In the related art, the air conditioner is usually equipped with a PTC (Positive Temperature Coefficient, positive temperature coefficient) type electric heating tube, and a thermostat and a fuse are arranged outside the electric heating tube. In such an abnormal situation, the electric heating tube will reduce the power of the electric heating tube and the temperature around the electric heating tube due to the positive temperature coefficient of the PTC inside it, and then the operating temperature of the thermostat and the fuse cannot be reached. It cannot protect the electric heating tube, so that the electric heating tube is always in a state o...
