Abstract

The invention discloses an electric heater for an indoor unit of an air conditioner. The electric heater comprises an electric heating element. The electric heating element comprises a heating part and radiation parts. An array consisting of the radiation parts is arranged on the surface of the heating part. The outer radiation edges, facing outside relative to the heating part, of the array consisting of the radiation parts are at least partially exposed in an outer space. The structure of the electric heating element is changed, so the electric heater decreases a space occupied by the heating part in the indoor unit of the air conditioner, reduces air supply resistance, increases a supply air rate, betters the radiation effects of the radiation parts, improves the performance of the indoor unit and reduces noises produced by the running of the indoor unit.

Description

technical field [0001] The invention relates to the field of air conditioner indoor units, in particular to an electric heater for the air conditioner indoor unit. Background technique [0002] PTC is a thermistor with a positive temperature coefficient. It has a high α coefficient and has good electrical resistance and aging resistance. It is currently widely used in indoor units of household air conditioners. When the external temperature drops, the resistance of ceramic PTC The value will decrease accordingly, and the heat output will increase accordingly. According to this principle, the air conditioner using ceramic PTC electric auxiliary heating technology can automatically change the heat output according to the change of room temperature and the air volume of the indoor unit, so as to properly The indoor temperature is adjusted to achieve the purpose of rapid and powerful heating. [0003] attached figure 1 The schematic diagram of the structure of the electric hea...
