Problems solved by technology

In particular, as the drying operation is performed, the humidity of the air discharged from the outlet of the drum becomes lower, and the air discharged outside that is not used for drying the object in the drum will cause heat loss, resulting in a decrease in thermal efficiency.

Embodiment Construction

[0047] Hereinafter, a laundry treatment apparatus having a heat pump cycle related to the present invention will be described in detail with reference to the accompanying drawings. In this specification, even if it is a mutually different embodiment, the same or similar structure is given the same or similar reference numeral, and the description is replaced with the description for the first time. Expressions in the singular include expressions in the plural unless a different meaning is clearly indicated in the context.

[0048] In the embodiment of the present invention, a condensation type clothes dryer that circulates air to dry items such as wet clothes is exemplified as a clothes treatment device, but the invention is not limited thereto. For example, other clothes dryers or washing machines with a drying function can also become the clothes treatment device of the present invention.

Abstract

A clothes treatment device, the clothes treatment device of the present invention comprises: a storage chamber for containing objects, a first heat pump cycle having a first evaporator, a first compressor, a first condenser and a first expansion valve, and a second heat pump Cycle, with a second evaporator, a second compressor, a second condenser, and a second expansion valve, the second evaporator and the second condenser are arranged so that the air flowing into the accommodation chamber passes through the first evaporator, the second evaporator in sequence A condenser, a second condenser and a first condenser, and a control unit to control the actions of the first heat pump cycle and the second heat pump cycle; wherein, at least one of the first compressor and the second compressor has a frequency converter, and the frequency converter The driving speed of the compressor is changed by frequency conversion, and the control unit uses the frequency converter to control the driving speed of at least one of the first compressor and the second compressor, so that at least one of the first compressor and the second compressor Operates within the set driving range.

Description

technical field [0001] The present invention relates to a laundry treatment device having a heat pump cycle for drying laundry and the like. Background technique [0002] Generally, a clothes processing device with a drying function such as a washing machine or a dryer puts the laundry in the state where the washing and dehydration process is completed into the drum, and supplies hot air to the inside of the drum to evaporate the moisture of the laundry and dry it. Device for washing. [0003] Clothes dryers can be classified into exhaust-type clothes dryers and condensation-type clothes dryers according to how humid air passing through the drum after drying laundry is treated. [0004] The exhaust type clothes dryer discharges the humid air that comes out of the drum to the outside of the dryer, and the condensation type clothes dryer does not discharge the humid air that comes out of the drum to the outside of the dryer, but The air is circulated and the humid air is coo...
