Problems solved by technology

In this kind of drum type washing and drying machine with high dehydration capacity, most of them have entered the decreasing rate drying process at the moment of transferring from the dehydrating process to the drying process, so that it is impossible to switch from the constant rate drying process to the decreasing rate drying process. Switches where the drying air goes during the drying process
[0008] In addition, the conventional structure only switches the direction of the drying air according to whether it is in the constant rate drying process or the decreasing rate drying process, and does not perform the drying operation while detecting the degree of drying of the clothes. In addition, It is also impossible to judge whether uneven drying has been sufficiently eliminated
[0009] Based on the above, the conventional structure has the problem that it is difficult to reliably reduce uneven drying of clothes.

Embodiment approach 2

[0120] Hereinafter, Embodiment 2 of the present invention will be described in detail with reference to the drawings.

[0121] The basic structure and the figure 1 , figure 2 , Figure 9 The drum-type washing and drying machines according to Embodiment 1 shown in the above description are the same, so the same part numbers are attached to the same configurations, and descriptions thereof are appropriately omitted.

[0122]The operation and effects of the drum-type washing and drying machine will be described in detail below focusing on differences from the drum-type washing and drying machine according to Embodiment 1. FIG.

[0123] In this embodiment, Figure 11 The shown control unit 170 accurately determines the degree of drying of the clothes in the drum 1 (the clothes on the outlet side are fully dried) based on the vibration value detected by the vibration detection unit 14 fixed to the support tub 2 . The principle is described below.

Embodiment approach 3

[0144] In Embodiment 2 above, the air volume or wind speed when selecting the first air passage 9 or the second air passage 11 is not particularly limited. For example, when selecting any air path, the same air volume and the same wind speed can be used. In contrast, in this embodiment, when the first air passage 9 is selected, the drying air with a larger air volume is blown from the first outlet 8 into the drum 1 than when the second air passage 11 is selected. When the second air path 11 is selected, the drying air of high pressure and high speed is blown from the second air outlet 10 into the drum 1 compared with the first air path 9, which can not only reduce power consumption but also reduce uneven drying , and can also reduce wrinkles of clothes based on high-pressure and high-speed drying air.

[0145] The basic structure and the figure 1 , Figure 9 , Figure 11 The drum-type washing and drying machines according to the first and second embodiments described above...

Abstract

The present invention provides a drying machine, including a first air duct (9) with a first blowoff opening (8) opened at a rare side of a drum (1); a second air duct (11) with a second blowoff opening (10) opened at a front side of the drum (1), the second blowoff opening (10) having a smaller cross-sectional blowing area than that of the first blowoff opening (8); wherein an air duct is switched between said first air duct and said second air duct in a drying process based on a result of determination by the entanglement determination section which determines if an entanglement of clothes has occurred in the drum (1), and where the first air duct (9) is selected, drying air of larger airflow quantity than that where the second air duct (11) is selected is spouted from the first blowoffopening (8), and where the second air duct (11) is selected, drying air at higher pressure and higher speed is spouted from the second blowoff opening than that where the first air duct (9) is selected. Thereby, it is possible to shorten drying time and reduce drape of clothing.

Description

technical field [0001] The invention relates to a clothes dryer for drying clothes and a washing and drying machine with washing function and clothes drying function. Background technique [0002] Conventionally, drum-type clothes dryers or washing and drying machines send drying air into the drum through air ducts, and make the drying air contact the clothes put into the drum and take moisture from the clothes to dry the clothes. In addition, the high-humidity drying air containing moisture is discharged to the air path outside the drum. In particular, since the clothes are dried in a limited and small drum space, the clothes are entangled with each other during the drying process and the air for drying cannot contact the entangled part of the clothes, which leads to an increase in the time required for drying, or during the entanglement In order to solve the problem that the clothes dried in the dry state are severely wrinkled, various methods have been studied (for examp...
