Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a powder supply device for a washing machine, and more particularly to a method and device for supplying chemicals such as detergent and bleach.

[Prior Art] Many washing machines are generally configured to supply powdered detergent, bleach, water softener, pHWA adjuster, and the like. However, there are various problems when supplying these powdered drugs. In particular, there was a problem that these powdered drugs could not be accurately measured. Furthermore, there is no suitable device that automatically supplies the appropriate amount of these chemicals into the washing tub during washing.

Furthermore, many of the above-mentioned drugs are hygroscopic. As a result, the surface of the drug absorbs moisture and hardens on the support stake, making accurate measurement impossible.

Devices that automatically supply this powdered drug have been developed. One of these devices includes a cleaning container in which a pre-metered amount of medication is contained. Then, at certain times during washing, the chemicals in the washing container are washed away with water and supplied into the washing tub together with the water.

However, this device has a number of drawbacks. for example,
With this device, a predetermined amount of chemicals must be supplied to the washing device each time the washing is done. Additionally, the medicine contained within this cleaning container may solidify before being flushed away by the water stream. Furthermore, this device is equipped with only one cleaning container and can only use one type of chemical.

Another example of this device is one in which a large amount of medicine is stored in a relatively large-capacity hopper. and,
A predetermined amount of medicine is taken out from within this hopper and supplied to the washing tub by an air conveyor. However, such a device is less reliable than the one described above in which the drug is washed away with water.

Such devices also have various other problems.

The biggest problem is that it cannot be adjusted. That is, in this type of device, it is not possible to adjust the measuring section that measures a predetermined amount of medicine from inside the hopper. therefore,
This device can only be applied to one type of drug per type of device.

Furthermore, since such a device is provided with only one hopper, only one type of drug can be used.

Furthermore, since the outlet of the pipe that supplies this chemical into the washing tub communicates with the washing tub, mixing may be incomplete and water sprayed into the washing tub may adhere to the outlet of this pipe. There were cases where the medicine hardened and became clogged near this exit.

Furthermore, no other device has been able to measure and supply powdered medicines using conveyor means.

For example, there is a system in which chemicals are directly supplied from a hopper to a washing tub by a flow of air, and the amount of medicine supplied is controlled by the air flow rate or the time for which the air is allowed to flow, depending on the type of medicine.

However, such devices are susceptible to blower failure, flow path clogging,
The supply amount of this drug changes depending on the type of drug and the like. Moreover, even if this blower is set to rONJ, this blower does not necessarily follow this accurately, and the supply amount changes every time it is activated. Furthermore, this device had the problem of not being able to compensate for changes in the physical properties of the powdered drug or changes in the length of the supply tube. In order to make such a correction, it is necessary to change the operation time of the feed mill or change the air flow rate.

Furthermore, other devices include movable parts such as brushes that come into contact with the mesh plate, and the drugs are supplied by the brushes. However, such devices tend to have problems such as clogging of the medicine and requiring frequent maintenance to prevent the accumulation of powdery medicine.

[Problems to be Solved by the Invention] The present invention solves the above-mentioned problems of the conventional device. More specifically, the present invention does not require washing. The present invention relates to a method and device for supplying powdered medicine into a washing tub of one device. The device of the present invention includes a measuring unit that measures a predetermined amount of medicine from a large amount of medicine stored in the hopper. The metered medicine is then transported by air into a washing container, where it is mixed with a solvent, formed into a solution, and then supplied to the washing tub. Therefore, the user does not need to meter and replenish the device with medication. Further, a shield member is provided within the cleaning container to prevent the solvent from entering the drug supply pipe and to prevent the drug from solidifying. Also, this mixing takes place during operation of the washing device.

Furthermore, since the device of the present invention is provided with a means for further controlling the supply of the predetermined and metered drug, collision between the drug and the transporting air flow is prevented. Therefore, the measuring mechanism only measures the medicine, and the transport means only transports the medicine to the cleaning container.

The present invention also relates to a method for supplying this drug to a washing tub. This method overcomes the drawbacks of the prior art and includes a drug metering step and a transport step, where the drug is mixed with a solvent and finally supplied to the washing tub.
