Problems solved by technology

[0011] But the heating device 106 that adopts traditional technology to make has following shortcoming: heating element 106a is semiconductor material, so starting current can reach 5~6 times of rated current when power is turned on, when the heat supply of heating device 106 increases, switch 106c and wires have to bear high current, so the volume is large, and the switch 106c has limited bearing capacity, and the switch 106c will leak electricity, so the heating device is limited to provide heat

Embodiment Construction

[0024] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0025] Such as figure 1 , figure 2 Shown, air conditioner indoor unit 1 of the present invention is by the box body 2 that air inlet 2a is arranged at the lower part of both sides and the air delivery port 2b is respectively arranged at both sides and front top; The fan 4 that enters and exits the box body 2; the heat exchanger 6 that is installed in the upper part of the box body 2 to realize cooling by the evaporation heat of the refrigerant, and the heating device 10 that realizes heating by relying on the heating element 12.

[0026] The heating device 10 is composed of a plurality of heating elements 12 of the same size that use the heat generated on the resistance to increase the ambient temperature during power supply; a power supply device 14 that provides current to one of the heating elements 12 at a certain time difference to minim...

Abstract

The invention discloses a heating device of air conditioner, which comprises several heating elements, of which at least one is supplied with current via power-supply unit. Power-supply unit comprises three-phase power, wire that connects heating element and three-phase power and switches that are equipped on circuit rail. Wire connects three-phase power and heating element in star attended mode. Due to heating unit connecting with three-phase power, the invention can reduce firing current and operating current with maximum range even if several heating elements works together to increase caloric power. Because heating elements are separated to three groups to be supplied with power in timing cycle with interval, the amount of current keeps low.

Description

technical field [0001] The invention relates to a heating device of an air conditioner, in particular to a heating device of an air conditioner which is equipped with a plurality of heating elements, and current flows through these heating elements with a certain time difference. Background technique [0002] Air conditioners using conventional technology such as image 3 and Figure 4 As shown, the indoor unit 100 is installed indoors to rely on the evaporation heat of the refrigerator for cooling or rely on heating elements for heating; it is connected to the indoor unit, and the refrigerant flowing out of the indoor unit 100 is condensed and sent into the indoor unit 100 An outdoor unit (not shown) for circulation. [0003] The indoor unit 100 is composed of a fan (102) that sends air into and outside the outdoor unit; the air that flows into the room from the indoor unit 100 is replaced by an indoor heat exchanger 104 that is cooled by the evaporation heat of the refrig...
