Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a rotary drum type clothes dryer for general household use.

Conventional Structure and Problems Conventionally, in this type of clothes dryer, clothes are placed in a drum, and warm air is blown by a heater while the drum is rotated.

In this case, if the amount of clothing is small, the clothing will rotate around the drum due to centrifugal force, and there will be no clothing near the center.
Space arises. However, the hot air intake hole into the drum is provided near the center of the rear surface of the drum to ensure uniform ventilation when a predetermined amount of clothing is loaded, and when hot air is blown into the drum from this hole, If the amount of clothing is small as described above, the warm air will directly pass through the space near the center where no clothing exists and be exhausted. For this reason, warm air is not blown toward the clothes, resulting in poor drying efficiency and long drying time.

Purpose of the Invention In order to solve this conventional problem, the present invention aims to store a small amount of clothing in a small drum that is detachably installed inside the drum, and to blow warm air onto the small amount of clothing. The purpose is to blow air efficiently.

Structure of the Invention The clothes dryer of the present invention includes a drum into which clothes are put, a heater for drying the clothes, and warm air passed through the heater introduced through an intake hole in the center of the rear surface of the drum. It has an air blower for blowing air onto clothes, and a small removable drum for small quantities of clothes is provided at the center of the rear surface of the drum so as to cover the air intake hole, and the hot air introduced from the air intake hole is It is configured to pass through a small drum.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figure 1, (1) is a drum into which clothes are put, a main body case surrounding it, and a lid (3) on the front of the drum that can be opened and closed with respect to the front opening. is provided with an annular drum front plate (4) into which the drum (1) is fitted at the front. At the front end of the drum 0), there is a drum holder that rotates and slides on the outer edge of the drum front plate (4).
5), and a front plate backing (6) is provided between the front opening of the main body case (2) and the inner edge of the drum front plate (4) to prevent hot air from leaking therebetween. (7) is the heater mounting plate close to the rear surface of the drum, and is attached to the main body case (1).
It is fixed by a support plate (9) provided on the rear surface (8).

00) is a heater, which is insulated and supported by a heater fitting Qυ fixed to the heater mounting plate (force).a is a drum (
The drum shaft is fixed to the rear surface θ3) of the drum (1), and is supported by one bearing via a bearing fitting (14J) fixed to the heater mounting plate (force), and rotatably supports the drum (1). 06) is the heater backing, and the drum (
1) Prevents air from flowing in between the rear surface and the heater mounting plate (outer edge of the force). (17), (I
ID, Q wing uses a drum (heater 00) to send warm air through the drum (
These are an intake hole on the rear surface of the main body, an intake hole on the heater mounting plate, and an intake hole on the rear surface of the drum, all of which are arranged to surround the drum shaft and are provided relatively in the center. On the other hand, there is an exhaust hole (20) at the bottom of the drum front plate (4).
is formed, and the warm air inside the drum is guided from this hole through the lint collecting device (2υ) into the exhaust stack A (23), and is passed through the exhaust pipe B (23) through the blower (23) located at the tip of this hole.
24) Exhaust the air. The fans (2) of the blower (23) are rotationally driven by a motor supported from the bottom of the main body case (2) via a metal fitting (26).
The drum belt that runs around the outer circumference of the motor (27
) drives the drum (1) to rotate.

According to the present invention, a small drum is provided to guide the warm air introduced by the drum intake person to a small amount of clothing.

This small drum (36) is located in front of the drum rear intake hole (tI) in the drum (1), and can be freely attached to and detached from the drum (1) with screws (31). To explain the operation, first, the motor (2
The rotation of 7) rotates the drum (1) via the drum belt (28), rotates the fan Q (G), and exhausts the air inside the drum from the front exhaust hole (2α). Air for replenishment is taken in from the intake hole (I7) on the rear side of the case (2) through the intake hole on the heater mounting plate (0 seconds), heated by the heater (00), and then heated into the drum (1) through the intake hole on the rear side of the drum. Introduced as Drum (1
The warm air that has passed through the clothes in the drum 1 absorbs moisture, passes through the lint collection device Qυ through the exhaust hole (20) of the drum front plate (4), passes through the exhaust pipe A (221, blower 123), and is sent to the exhaust pipe BQ ( stomach)
It is exhausted to the outside of the main body (2).

In addition, in this ventilation path, the lint coming out from the clothes in the drum (1) is collected by the lint collecting device Cυ by the exhaust person on the drum front plate (4).

The effect of a small drum is especially effective when there is little clothing. That is, in the case of a small amount of clothes, the rotation of the drum (11) positions the clothes at the outer periphery, and the center of the drum (1) creates a space where the clothes do not pass.The warm air passing through this space does not contribute to drying. The heat loss of the heater results in poor drying efficiency and long drying time. Then, the hot air passes through the clothes in the small drum (30), which improves drying efficiency and reduces heater loss.

Effects of the Invention As is clear from the above embodiments, the clothes dryer of the present invention is equipped with a small drum to efficiently blow warm air to the small amount of clothes, especially when there is a small amount of clothes. This allows for efficient drying with less loss.
