DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine for carrying out bio-washing of an object to be washed using an enzyme such as a protease or a cellulose fibrinolytic enzyme.

[0002]

2. Description of the Related Art Silk clothing and thin fashion clothing are vulnerable to mechanical action, heat, chemicals, and the like. Shrinking, uneven color, discoloration, and the like may occur with a cleaning device using a normal petroleum-based solvent. Will happen. Therefore,
A bio-washing method has been developed in which an object to be washed is washed using an enzyme such as a proteolytic enzyme or a cellulose fibrinolytic enzyme.

An example of a bio-washing machine used in this bio-washing method is disclosed in Japanese Patent Application Laid-Open No. 2-136169. This bio-washing machine cooperates with the washing liquid storage tank and the existing washing and dehydrating machine with a circulation device that circulates the washing liquid,
In addition, a warming device for keeping the washing liquid at a predetermined temperature is provided in the circulation circuit, and a bubble generating device is provided for the washing and dehydrating machine. The supply port for supplying the washing liquid to the washing and dehydrating machine is provided only in the upper part of the washing and dehydrating machine.

Another example of a bio-washing machine is disclosed in
No. 146099. This bio-washing machine is provided with a plurality of tanks for each washing liquid containing an enzyme suitable for the fiber of the object to be washed, and divided into the plurality of tanks and the existing washing and dehydrating machine according to the type of fiber of the object to be washed. A circulation device that circulates the washing liquid separately is connected, and a plurality of tanks are separately equipped with a warming device that maintains the temperature of the washing liquid, which is divided according to the type of the fiber to be washed, at a temperature suitable for activating each enzyme. Is provided.

[0005]

However, the conventional washing machine disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2-136169 requires a pump for sending the washing solution from the washing solution storage tank to the washing and dehydrating machine. There is a problem that not only the device becomes complicated, but also the manufacturing cost increases. In addition, since the cleaning liquid is circulated using the circulation device, and the same cleaning liquid is used in a plurality of cleanings, the cleaning liquid is contaminated every time cleaning is performed, and the accumulated contaminants adhere to the object to be cleaned. There was also. Further, since the preparation of the cleaning liquid has to be performed while the operation of the cleaning machine is stopped, there is a problem that the working efficiency is reduced. Further, since the washing liquid is supplied only from the upper part of the washing and dehydrating machine, most of the supplied washing water flows down between the outer and inner shells of the washing and dehydrating machine and flows down to the lower part of the washing and dehydrating machine. I will. Therefore,
If a part of the object to be washed protrudes out of the washing liquid during washing, the part does not sufficiently contact with the washing liquid, so that not only the dirt is not removed but also the washing remains. In addition, this washer can only be used for biowashing only,
There was also a problem of lack of versatility.

[0006] The above-mentioned problem is described in Japanese Patent Laid-Open No. 3-14609.
The same applies to the washing machine disclosed in Japanese Patent Application Laid-Open No. 9-109, and furthermore, in this washing machine, a plurality of tanks for storing a plurality of kinds of washing liquids and a circulation for separately circulating the washing liquids stored in the plurality of tanks Since the apparatus and the heat retaining device separately provided in each of the plurality of tanks are provided, there is a problem that the device is further complicated and the manufacturing cost is increased.

The present invention has been proposed in view of the above-mentioned problems of the prior art, and has as its object to eliminate unevenness in washing, improve work efficiency, and further reduce the manufacturing cost. Not bio , bio
An object of the present invention is to provide a versatile washing machine that can be washed .

The dye transfer preventive agent b is charged into the drum device 2 from the first detergent pipe 18 through the first detergent inlet 17. When the supply of the washing liquid is completed, the object to be washed is immersed in the washing liquid for a predetermined time. During this time, the washing liquid in the washing liquid tank 4 is supplied to the spray nozzle 10 by the washing liquid circulation pump 11, and the washing liquid is sprayed into the drum device 2 from the front surface of the drum device 2 in a shower shape. Therefore, the washing liquid is evenly poured down onto the object to be washed out of the liquid level of the accumulated washing liquid in a shower shape.

The temperature of the washing liquid in the washing liquid tank 4 is measured by the first temperature measuring device 51 and is a predetermined temperature, for example, a temperature range in which the enzyme is actively activated.
It is heated by the first heater 52 so as to reach 〜40 ° C. Therefore, the dirt adhering to the object to be washed is easily separated and purified by the action of the enzyme, and the washing effect can be efficiently performed without unevenness in combination with the shower effect.

In this cleaning step, the rotating drum 13
Although the immersion washing is performed without rotating the rotating drum, the rotating drum 13 may be rotated at an extremely low speed depending on the type of the article to be washed. The rotation speed of the rotating drum 13 in this case is, for example, about 32 rpm.
, And rotate it forward and backward at regular intervals so that the object to be washed is not entangled. This cycle is, for example, operated for 13 seconds and paused for 3 seconds. This mode can be set. When the rotating drum 13 is rotated, a washing mode such as intermittent washing or swing washing can be selected.
The intermittent washing mode refers to a washing mode in which a process of rotating the rotating drum 13 for 5 seconds and stopping the rotating drum 13 for 15 seconds is repeated, for example, and the swing washing mode refers to, for example, the rotating drum 13 for 0.75 seconds. Is a washing mode in which the step of rotating the drum 13 for five seconds is repeated.
