Description

Separating Drum Washing Machine {WASHING MACHINE HAVING PLURAL DRUM}

According to the present invention, two washing tanks may be provided at the same time, or two washing tanks may be used at the same time, or one washing tank may be selectively used. A drum washing machine obtainable, more specifically, two or one washing tank by combining each power train to two washing tanks, and optionally operating each power transmission unit simultaneously or selectively. It relates to a drum washing machine that can save power, save water and save time in the washing process.

In general, as shown in Figure 4, the drum washing machine is provided with a cylindrical outer tub 51 inside the main body 50, the rotating tub 52 is provided rotatably installed in the outer tub 51, and rotates A power transmission device 53 is provided to transmit the driving force of the motor 54 to the rotating tank 52 so that the tank 52 is rotated. A water supply device and a detergent supply device for supplying washing water and detergent are provided. It is provided. And, the washing water is provided with a heater, one side of the main body is provided with a water level sensor for detecting the level of the wash water and a temperature sensor for detecting the temperature of the wash water.

Unlike the washing machine of the general washing plate type washing machine as described above, by washing the laundry using the force falling from the top to the bottom by the left and right rotation of the rotary tub 52 in the hot water in addition to washing, rinsing, dehydration Boil, wash and dry. The drum washing machine has the advantage that the laundry is not tangled and damaged and uniform washing is made, and the amount of water used is smaller than that of the washing machine.

However, a drum washing machine which performs all the washing processes in a series also needs to be separated and washed in the washing process. for example,

a) When separate washing is necessary according to the material of washing

In particular, there are many clothes made of various materials in winter than in summer, for example, laundry made of wool and cotton. Wool and cotton are often unable to share the same washing time, and the washing water temperature cannot be the same. In addition, there is a case that washing with the same detergent may not occur, and even if the same detergent is used, there is a risk of damaging the laundry. In addition, it is not easy to wash the washing strength according to the average value due to the nature of the laundry material.

b) separate washing is required according to the color of the laundry;

Unlike the winter season, the summer season wears clothes of various colors, especially the primary color system, so the laundry also comes out a lot of primary colors, while white clothes are one of the favorite colors in summer, so as much as the primary laundry. As such, in the summer, when a lot of primary colors and white laundry come out, the white laundry is frequently damaged by water of the primary color laundry unless the laundry is separated.

As such, when the separate washing according to the laundry material or the color of the laundry is very common, it must be separated for washing.

Therefore, washing becomes very troublesome, and in the case of purchasing clothes, even a favorite clothes may not be purchased. In addition, due to the separate washing, the washing time takes longer than two hours, and when the laundry is a lot of cases may take more time. In addition, since a series of washing processes must be repeated several times, waste of washing water and detergents is increased, and thus, electricity consumption is increased.

On the other hand, a conventional drum washing machine that separates the laundry to perform the washing process is known (Korean Patent Publication No. 2001-0088209). However, the conventional drum washing machine merely intends to separate washing by simply installing a plurality of washing tanks 52a and 52b, and does not consider the concept of power saving effect and washing time depending on the washing amount (see FIG. 5). for example,

c) if the load is not high,

When washing a small amount of laundry (simple laundry-handkerchief, shorts, swimwear, sportswear), the washing machine's motor is large enough to perform the washing by rotating two wash tanks, but the relatively small amount of washing does not cause excessive power consumption. It is prepared, and the laundry tank containing no laundry is rotated at the same time, so that the power consumption is increased, so it is not efficient.

In addition, a conventional washing machine is not suitable for use in a place where a small amount of laundry is to be washed, such as a swimming pool, a gymnasium, a studio house, or the like.

Accordingly, the present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to provide a drum washing machine having two washing tanks to enable separate washing to prevent damage to the laundry.

An object of the present invention is to provide a drum washing machine having a first washing tank having a relatively large capacity and a second washing tank having a relatively small capacity to simultaneously or selectively use the first washing tank and the second washing tank according to the washing amount. By reducing the power consumption required for washing and saving detergent, washing water, and washing time.
