Abstract

PURPOSE:To reduce a load on a motor even when the height of a movable baffle is lowered when washing contains a large amount of water and to efficiently perform dehydration and drying by a motor of low torque by providing with a hollow baffle of two fixed baffles and the movable baffle positioned between those fixed baffles, and setting the movable baffle so that needle and bobbin thread can be moved. CONSTITUTION:When the washing, drainage, and dehydration of the washing are performed by inputting in a rotary drum 2, the height of the movable baffle 9 of the hollow baffle 5 located at a lower side is lowered since the washing contains a large amount of water at the beginning, and the washing is rotated at the lower side without floating to the upper side in the rotary drum 2. Therefore, it is enough to provide low torque for a driving motor 6. Since the weight of the washing is reduced gradually according to the lapse of time, the height of the movable baffle 9 is raised therefore, the washing is floated to the upper side of the rotary drum 2, which performs the dehydration or drying with high efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a drum-type washing machine that washes, dehydrates, and dries laundry such as clothes.

Conventional Technology In recent years, drum-type washing machines have been mainly used in Europe, but they are also beginning to become popular in Japan because their structure allows them to go through drying cycles.

Conventionally, this type of drum-type washing machine generally had a configuration as shown in FIG. The configuration will be explained below.

As shown in the figure, the outer tank 11 is capable of storing washing water, and rotatably supports a rotating drum 12 therein. On the inner surface of the circumferential wall of the rotating drum 12, a wall protrudes inward in the direction of the drum rotation axis. Hollow baffle 1 with a substantially chevron-shaped cross section as shown in Figure 6
3 was set.

Problems to be Solved by the Invention In such conventional drum-type washing machines, the rotating drum 12
When putting laundry inside and dehydrating and drying it, hollow baffle 1
If the height of 3 is higher than a certain level, (1,.

Since the laundry is lifted above the rotating drum 12,
The torque of the drive motor 14 is also very large, and if the laundry contains a lot of water, it is very likely to vibrate. In addition, when the height of the hollow baffle 13 is low, the torque of the drive motor 14 can be small, but since the laundry rotates in a dumpling shape below the rotating drum 12, the dehydration rate is poor, and when drying, Since the laundry does not reach above the rotating drum 12, there is a problem in that the drying efficiency is poor.

The present invention solves the above problem, and when the cloth contains a lot of water, the height of the hollow baffle is set to be low,
The aim is to increase the height of the hollow baffle as the water content decreases, allowing for efficient dewatering and drying using a motor with low torque.

Means for Solving the Problems In order to achieve the above objects, the present invention has two hollow baffles.
The problem is solved by making the movable baffles between the fixed baffles and the movable baffles vertically movable using elastic members such as VF springs and rubber materials.

Effect of the Invention The present invention has the above-mentioned means for solving the problems, and when the cloth contains a lot of moisture, the movable baffle is lowered in height against the elastic member due to its weight, and the torque of the motor that drives the rotating drum is lowered. It is also small, and vibrations are also reduced. As dehydration or drying progresses, the weight of the laundry becomes lighter, so the height of the movable baffle increases due to the elastic member, and the cloth is pushed upwards, improving dehydration or drying efficiency.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3.

As shown in the figure, the outer tub 1 is capable of storing washing water, and has a rotary drum 2 rotatably supported therein.

A plurality of through holes 3 are formed in the circumferential wall of the rotating drum 2, and an arbitrary number of hollow baffles 5 protrude inwardly in the direction of the drum rotation axis 4 from the inner surface of the circumferential wall. A certain amount of water and laundry are put into the rotating drum 2, and the belt 7 is moved by the driving motor 6.
The rotary drum 2 is rotated through the rotary drum 2 to wash or dehydrate the laundry.

In that case, a hollow buff/I15 is provided so that the laundry rotates as the rotary drum 2 rotates.

As shown in Fig. 2, the hollow baffle 6 consists of two fixed baffles /l/8.8 and a movable baffle 9 provided between these fixed baffles 8, 8, and the movable baffle 9 has a spring at the bottom. , an elastic member such as a rubber material 1° is provided to enable vertical movement. In other words, if the weight applied to the movable baffle 8 is light, the fixed baffle /L/8
．． 8 and the movable baffle 9 form a mountain shape, and as the weight increases, the movable baffle /I/9 becomes lower as shown in FIG. ' To explain the operation in the above configuration, when laundry is placed in the rotating drum 2 and drained and dehydrated after washing, the laundry initially contains a lot of moisture, so it is placed at the bottom and is placed in the air. As shown in FIG. 3, in the baffle/I/6, the height of the movable baffle 9 is lowered, and the laundry does not rise above the rotating drum 2 but rotates below it. Therefore, the torque of the drive motor 6 can also be small. As time passes, the weight of the laundry gradually becomes lighter, so the movable buff/I
Since the height of /9 is increased, the laundry rises above the rotating drum 2 and can be efficiently dehydrated or dried. Also, regarding vibrations, when the laundry contains a lot of water, the laundry rotates small below the rotary drum 2, so the vibrations do not become large.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the hollow baffle is different from the two fixed baffles and the movable baffle provided between these fixed baffles, and the movable baffle is moved up and down by an elastic member. Because it is movable, when the laundry contains a lot of water, the height of the movable baffle is lowered, reducing the load on the motor, and once the laundry has been dehydrated to a certain extent, the height of the movable baffle becomes higher and the torque is reduced. A small motor allows for efficient dewatering and drying.
