Abstract

[Challenge] To achieve uniform drying while suppressing the prolongation of drying time. [Solution] The garment processing apparatus of the embodiment comprises a rotating tub capable of accommodating garments, a motor that rotates the rotating tub, a hot air supply device that circulates and supplies hot air to the rotating tub through a circulating air passage, and a control device that controls the operation of the motor and the hot air supply device. The control device is capable of performing an operation that includes a preheating dewatering step in which the garments are dewatered and heated by performing both the blowing operation and the heating operation. In the preheating dewatering step, the control device can perform rotation speed change control, which includes a first control that controls the rotation speed of the rotating tub to a first rotation speed, followed by a second control that controls the rotation speed of the rotating tub to a second rotation speed lower than the first rotation speed, and then a third control that controls the rotation speed of the rotating tub to a third rotation speed.

Description

Embodiments of the present invention relate to a garment processing apparatus. For example, garment drying devices such as washer-dryers use either a heater or a heat pump. Drying with a heat pump offers advantages over heater-based drying, including greater energy efficiency, lower heating temperatures, and less wrinkles and shrinkage. In washer-dryers, washing conditions, such as the weight of the clothes, typically vary each time, and heavier clothes require longer drying times. Because of this, it's difficult to accurately predict the drying time in advance, and the drying time may be longer than expected. To address these challenges, the conventional technology described in Patent Document 1 employs a configuration in which, after rotating the rotating tank at a predetermined speed range to remove moisture from the clothing inside the tank by centrifugal force, a control means is provided to set the operating frequency of the compressor at startup higher than the case where the high-speed rotation was relatively low within the speed range, compared to the case where the high-speed rotation was faster than the low-speed rotation. Hereinafter, the conventional technology described in Patent Document 1 may simply be referred to as the conventional technology. However, drying with a heat pump, as used in conventional technology, takes time for the temperature to rise. Therefore, in the above configuration, in the initial stages of drying, it is more efficient in terms of time to reduce the moisture content of the clothes by performing high-speed spinning to dewater them. However, conventional technology has problems such as vibration, noise, and the strength of the bearings supporting the drum, making it impossible to reach the maximum rotation speed under all imbalance conditions. This leads to problems such as a large amount of residual water, resulting in longer drying times and variations in operating time, as well as issues with vibration and noise. On the other hand, while heater-based drying has the advantage of easily raising the temperature, it presents a challenge in achieving uniform drying of all clothing due to the tendency for uneven drying.

Several embodiments will be described below with reference to the drawings. In each embodiment, substantially identical components are denoted by the same reference numerals and their descriptions are omitted. (First Embodiment) The first embodiment will be described below with reference to Figures 1 to 6. As shown in Figure 1, the washer-dryer 1 of this embodiment is a so-called drum-type machine equipped with both washing and drying functions for clothes. The washer-dryer 1 is capable of performing operations such as washing, rinsing, spinning, and drying on clothes, and is an example of a clothing processing device. The washer-dryer 1 can perform washing operations and washer-drying operations as operations including a washing process for washing clothes, and can also perform drying operations and washer-drying operations as operations including a drying process for drying clothes. In a wash-and-dry cycle, the entire process from washing to drying is performed automatically. The washing process includes a washing cycle, a rinsing cycle, and a spin-drying cycle. Furthermore, the washer-dryer 1 can perform a preheating and spin-drying cycle (described later) prior to executing the drying cycle. The outer casing 2 of the washer-dryer 1, a roughly rectangular box, has a door 3 at the center of the left front 2a in Figure 1, i.e., the center of the front of the washer-dryer 1, which allows for opening and closing the clothes loading opening.
