Description

Clothes drying temperature control device and clothes dryer

Technical Field

The utility model belongs to the technical field of the dryer, concretely relates to dry clothing temperature regulating device and dryer.

Background

At present, most clothes dried and washed by people are dried in the sun or naturally, the drying time is long, the clothes are hung outside and stuck with dust, and the clothes are more difficult to dry particularly in rainy days or cold days. For high-rise residents in cities and towns, the airing space is limited, and sunlight is insufficient, so more and more people select clothes drying equipment for drying clothes.

Clothes drying equipment can be roughly divided into a heating dehumidifying type and a negative pressure heat pump type according to a clothes drying principle. Chinese patents CN2414671Y and CN1139163A disclose heating and dehumidifying methods, which both bake wet clothes with heated air by using a heat pump or a heater and cool and discharge the wet air, so as to dry clothes.

The negative pressure heat pump type disclosed in chinese patents CN2780810Y and CN102011294B mainly creates a low pressure environment for clothes, thereby reducing the boiling point of water and achieving the purpose of evaporating water rapidly at a lower temperature. However, the negative pressure heat pump system requires a vacuum environment, is expensive and difficult to manufacture, and requires special attention to safety during use, so that the negative pressure heat pump system cannot be marketed at a later date.

As shown in fig. 1, the current clothes drying system generally includes an accommodating space 01, a blower 02, an evaporator 03, a condenser 04, and a drainage mechanism (not shown), and referring to fig. 1, the principle of clothes drying in the clothes dryer is that wet air in the accommodating space 01 passes through the evaporator 03 to remove water, then passes through the condenser 04 to heat the cooled dry air, and then returns to the accommodating space 01 to exchange the temperature and humidity with clothes. When the temperature of the accommodating space is too low, moisture is not easy to evaporate, the condenser is required to dissipate heat to enable the temperature of the accommodating space to rise, but when the temperature of the accommodating space is too high, if the temperature of the accommodating space exceeds 42 ℃, the temperature of the accommodating space can exceed the normal working condition of a dehumidification system, and the system cannot work normally, so that the temperature of the accommodating space needs to be controlled within a certain range. However, in the prior art, good temperature control cannot be realized.
