Abstract

PURPOSE:To improve drying efficiency, to reduce drying non-uniformity and to reduce a sound to be generated in a drum by providing a cylindrical drum supporting body to cover the drum equipped with plural small circular holes, to form the air duct of hot air and to support the drum. CONSTITUTION:Since the hot air heated by a heater 6 is fed from drum side part small circular holes 23 and drum barrel part small circular holes 24 into the rotary drum, the hot air hits whole clothes even when the amount of the clothes put into the rotary drum is large. Then, the clothes are extremely satisfactorily dried with the small drying nonuniformity in a short time for drying. Since double structure is obtained for a rotary drum 2 and a cylindrical drum supporting body 12, the sound to be generated in the drum is interrupted by the said cylindrical drum supporting body and a quiet clothes dryer can be presented while reducing the sound to be leaked out of a main body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drum-type clothes dryer, and particularly to improvements in the drum and ventilation passage structure that improve the drying performance of clothes. [Prior Art] As shown in FIG. 2, a conventional clothes dryer has a front surface of a drum 25 supported by an annular drum support 27 fixed to an outer frame 26, and a central portion at the rear of the drum 25. It is supported by a drum shaft 28 protruding from the top. Annular drum support 2
A heater is installed inside the drum 7, and hot air is sent out through a plurality of small circular holes provided substantially at the bottom of the surface of the annular drum support. Further, the drum support 27 does not cover the drum 25. [Problems to be Solved by the Invention] In the prior art described above, the hot air outlet is located substantially at the bottom of the annular drum support, so the hot air is blown out only from the front surface of the drum. Therefore, when the agitation condition of the clothes is poor, such as when there is a large amount of clothes put into the drum, the clothes near the heater are dried well, but the clothes at the rear of the drum are not well hit by hot air and the drying time is longer. There were problems such as drying and uneven drying. Furthermore, when drying clothes with zippers or buttons, there is a problem in that the buttons and the like hit the drum wall and make a very noisy sound when the clothes fall. The purpose of the present invention is to have good drying efficiency without the above-mentioned drawbacks,
An object of the present invention is to provide a clothes dryer that can reduce uneven drying and reduce noise generated within the drum. [Means for Solving the Problems] The above object is to provide a plurality of small circular holes in the whole or a part of the drum, and further cover the whole or part of the front surface and the body of the drum in which the small circular holes are provided, This is achieved by providing a cylindrical drum support that forms a hot air ventilation path and supports the drum. [Function] Warm air is blown through the plurality of small circular holes provided in the whole or part of the drum and the cylindrical drum support that forms the hot air ventilation path, so even when the clothes are not well agitated, Warm air will now hit all the clothes in the drum. Therefore, it is possible to provide a clothes dryer with shorter drying time and less uneven drying. In addition, since the drum for batter VTM stirring and the cylindrical drum support have a double structure,
The sound generated inside the drum is agitated by the cylindrical drum, reducing the sound leaking outside the outer frame. [Example] An example of the present invention will be described below. In FIG. 1, 1 is the main body of the dryer, 2 is a rotary drum rotatably provided in the main body 1 and driven by a motor 3 via a drum belt 4, and 5 is a clothing input provided on the front of the main body 1. It has a sealed structure with a door 21 at the mouth. The rotating drum 2 is supported by a cylindrical drum support 12 that covers the drum body and the side outside the clothes input port and is fixed to the main body 1. The body 12 is held airtight by an airtight felt 22. 6 is a heater that heats the drying air flowing into the rotating drum 2 through the small circular hole 23 on the side of the drum;
Further, the drying air is also directed into the rotating drum 2 through a small circular hole 24 provided in the drum body. 7 is a heat exchange fan installed at the rear of the rotating drum 2, which has air blowing and heat exchange functions, and is driven by a motor 3 via a fan belt 8. A casing 9 is provided on the rear surface of the rotating drum 2, and has an intake port 10 on the rotating drum side in the center. 11 is a filter installed on the rear surface of the rotating drum 2 to remove lint, etc.; 17;
is a mounting plate fixed to the rear of the main unit, and the heat exchange fan 7 rotates! 1! l 1 4 and casing 9
It also has the function of fixing the partition plate 15 to the main body 1. 20 is a back plate that covers the rear surface of the main body 1; 13 is a cooling side intake port provided for sucking outside air for cooling into the heat exchange fan 7;
Reference numeral 19 denotes a cooling side exhaust port provided on the back plate 20 for exhausting outside air for cooling after heat exchange to the outside of the main body 1. Reference numeral 15 denotes a partition plate that divides the outer circumference of the heat exchange fan 7 into left and right sides, airtightly separating the ring side and the cooling side. Reference numeral 16 denotes a circulation duct, which functions as a ventilation path for guiding the exhaust air from the circulation side of the casing 9 to the heater 6, and 18 is a drain port for discharging condensed water generated by heat exchange in the heat exchange fan 7. During drying, the hot and humid circulating air is cooled and heat exchanged by the heat exchange fan 7, so the moisture is condensed, and the dehumidified air is heated by the heater 6 and introduced into the rotating drum 2 again. Ru. Drying progresses through the above drying cycle. In Fig. 1, arrow A indicates the flow of circulating air, and arrow B indicates the flow of cooling air. In the clothes dryer having the above structure, when the ffli is input, the motor 3 is driven and the rotating drum 2 containing the clothes to be dried is driven.
rotates, and at the same time rotates the heat exchange fan 7. As a result, the high temperature and humidity inside the rotating drum 2 is sucked into the heat exchange fan 7 through the rotating drum side intake port 10, heat is exchanged on the surface of the heat exchange fan 7, and water generated by condensation is discharged from the drain port 18 of the main body. 1 It is discharged outside. In addition, the air dehumidified by condensation passes through the circulation duct 16 and is heated to the heater 6.
It is heated here and circulated into the rotating drum 2 through a small circular hole on the side of the drum. Further, the air heated by the heater 6 is transferred to the rotating drum 2 and the cylindrical drum support 1.
B of 2 is also fed through the small circular hole in the body of the re-drum. Furthermore, at the same time as the circulating air flows due to the rotation of the heat exchange fan 7, air also flows within the back plate 20. This air flow is guided from the outside of the main body 1 through the cooling side intake port 13 to the heat exchange fan 7 as shown by arrow B, and after removing heat from the circulating air flow (arrow A), He ends up wandering outside. According to this embodiment, the warm air heated by the heater 6 is sent into the rotating drum through the small circular hole on the side of the drum and the small circular hole on the drum body, so when a large amount of clothing is put into the rotating drum, The warm air blows over the entire garment, allowing for very good drying with short drying time and less uneven drying. In addition, since the rotating drum 2 and the cylindrical drum support 12 have a double structure, the sound generated inside the drum is interrupted by the cylindrical drum, and the sound leaking outside the main body 1 is reduced, making it very quiet. We can provide a clothes dryer. [Effects of the Invention] According to the present invention, even when a large amount of clothes are put into the rotating drum, warm air is applied to the entire clothes, so the drying time is short and clothes are dried with less uneven drying. be able to. In addition, since the rotating drum and cylindrical drum support have a double structure, the sound generated inside the drum is intercepted by the cylindrical drum, reducing the amount of noise leaking outside the main unit, resulting in extremely quiet clothes drying. We can provide you with a machine.
