Embodiment Construction

[0023] According to the control method of the frequency conversion heat pump clothes dryer in the present invention, the clothes dryer includes at least two clothes drying modes: the first clothes drying mode and the second clothes drying mode, and the compressor in the first clothes drying mode The running time of the high frequency section is longer than the running time of the high frequency section of the inverter compressor in the second drying mode. The drying speed of the first drying mode is faster than that of the second drying mode, and the power consumption of the second drying mode is lower than that of the first drying mode. If the drying mode is selected, the control panel is provided with a control button for the drying mode, and the user selects the drying mode through the panel buttons.

[0024] The operating frequency or speed of the fan in the first drying mode is higher than or equal to the operating frequency or speed of the fan in the second drying mode. ...

Abstract

The invention relates to a method for controlling a frequency conversion heat pump clothes dryer. The clothes dryer includes at least two drying modes; the drying modes include a first drying mode and a second drying mode; the run time of a compressor at a high frequency band in the first drying mode is longer than the run time of a frequency convertible compressor at the high frequency band in the second drying mode; the frequency convertible compressor includes a frequency raising stage, a frequency maintaining stage, and a frequency reducing stage; in the frequency reducing stage, the frequency of the compressor gradually and periodically declines form a set target frequency till drying ends, and the detection temperature corresponding to the frequency of the compressor which gradually and periodically declines form a set target frequency, in the first drying mode is higher than that in the second drying mode.

Description

technical field [0001] The invention relates to the field of clothes dryers, in particular to a control method for a frequency conversion heat pump clothes dryer. Background technique [0002] In daily life, clothes are mostly dried by natural drying. However, it takes a long time to dry clothes by natural drying. Especially in the mild rainy season in the south, it is difficult to dry them after drying for many days. Therefore, clothes dryers are more and more favored by users, but now Most of the drying modes with dryers are relatively simple. Consumers have further demands for humanized operation modes of dryers, which are mainly manifested in the following three aspects. Demand 1: When using dryers at night when people are resting, they require The noise should be low. Requirement 2: When the user is in a hurry, it is necessary to meet the user's higher requirements for the drying speed. Requirement 3: When the user is not very anxious about the drying speed, the requir...
