Method for controlling the operation of a dryer

Abstract

The present invention relates to a dryer. A method for controlling the operation of a dryer, comprising a heat pump having a variable compressor, comprises the following steps: selecting at least one dryer operating course for supplying air or drying air; raising the compressor driving speed to a target speed while the selected dryer operating course is proceeding; and adjusting the degree of opening of an expansion valve of the heat pump.

Description

technical field

[0001] The invention relates to a control method of a dryer. Background technique

[0002] The washing apparatus may be classified into a washing machine performing a washing operation, a dryer performing a drying operation, and a combined drying washing machine performing both washing and drying operations. A dryer is a device that dries an object by supplying heated drying air, and various types of dryers are currently being developed. But this dryer also comes with many problems. Contents of the invention

[0003] technical problem

[0004] An object of the present invention is to provide a control method capable of realizing stable operation of a compressor in the early stage of driving a heat pump. That is, an object of the present invention is to provide a control method for preventing refrigerant in a liquid state from flowing into the compressor at the initial stage of driving the compressor. Furthermore, an object of the present invention is to...

Embodiment Construction

[0022] Hereinafter, dryers in different embodiments will be described in detail with reference to the accompanying drawings.

[0023] figure 1 It is a perspective view which shows the dryer of one Example.

[0024] refer to figure 1 In one embodiment, the dryer 100 may have a cabinet 110 forming an appearance. And, the dryer 100 may have a drum 120 rotatably installed inside the cabinet 110 . The inside of the drum 120 can accommodate washing objects. Although not shown, the dryer 100 may further have a user operation part (not shown) that receives at least one piece of drying information. The user can select drying information such as a desired course through the user operation part. Furthermore, the dryer 100 has a control unit (not shown) that generates operation information based on the drying information input through the user operation unit.

[0025] On the other hand, the dryer 100 of an embodiment may have a heating unit that supplies dry air to dry laundry objec...
