Description

All-in-one washing machine {WASHING MACHINE WITH DRYER}

The technical idea of the present invention relates to a washing machine integrated with a dryer, and more particularly, to a commercial washing machine configured with a washing machine and a dryer as a whole.

Existing washing machines are composed of a dryer and a separate device, so when using a dryer, they take up a lot of space, and in many cases, a washing machine and a dryer are stacked up and down at home, but this also requires a small amount of space. In addition, there is the inconvenience that the user has to take the laundry out of the washing machine and move it to the dryer.

In addition, in the case of a coin laundry, there is a problem that requires a large amount of space because each of the washing machines and the dryer must be set separately. In particular, in the case of a coin laundry, the user has a more troublesome problem of taking laundry out of the washing machine and moving it to the dryer.

In one embodiment, the heating unit 530 may correspond to the heating units 230 and 330 illustrated in FIGS. 2 and 3, respectively.

In one embodiment, the control unit 510 may control the power unit 520 and the heating unit 530. In one embodiment, the controller 510 may include at least one processor and memory, but is not limited thereto.

In one embodiment, the control unit 510 may perform functions such as cost settlement, laundry control, and dry control.

Hereinafter, embodiments of the washing machine control method that can be performed by the control unit 510 will be described in detail.

In one embodiment, the control unit 510 may automatically determine the washing and drying time according to the cost.

In one embodiment, the control unit 510 may obtain cost payment information for using the washing machine. The cost payment information may be obtained from information on the cost input through the cost settlement unit of the washing machine, or may be obtained from a payment system connected to the washing machine.

In one embodiment, the control unit 510 may obtain the weight of the laundry accommodated in the rotating drum. For example, the control unit 510 may acquire the weight of laundry using at least one weight sensor.

The control unit 510 may determine the washing time and the amount of detergent based on the obtained weight. For example, as the laundry is heavier, the washing time and the amount of detergent may increase.

The control unit 510 may calculate the washing cost based on the determined washing time and the amount of detergent. According to an embodiment, the washing machine 500 may have a structure in which a detergent is automatically introduced by incorporating a detergent, or a structure in which a detergent is separately added.

The control unit 510 may calculate the washing time and allow the user to input detergent by automatically injecting or discharging the required amount of detergent. The input of detergent may be performed through a separate device.

The control unit 510 may calculate the washing cost according to the washing time and the amount of detergent, and calculate the drying cost by subtracting the calculated washing cost from the amount corresponding to the cost payment information. That is, the controller 510 may limit the washing cost and use the remaining amount for drying.

The control unit 510 may calculate a drying time corresponding to the drying cost, and may perform drying for the calculated drying time in the drying step.

That is, the more money the user puts in, the longer the drying time can be.

Accordingly, if the user determines and pays the budget for the laundry cost without complicated calculation, the control unit 510 may automatically perform washing and drying within the budget range.

In one embodiment, the control unit 510 may adjust the temperature of the heat supplied during drying.

Depending on the type of laundry, when excessively high heat is supplied, the laundry may excessively shrink, and in this case, the laundry may be damaged.

The control unit 510 may measure the centrifugal force of the rotating drum rotating in the drying process in real time using at least one sensor, and obtain corresponding information.

At this time, when the measured centrifugal force increases above a preset reference value, it can be determined that the laundry contracts. As the volume of the laundry becomes smaller, the center of gravity of each laundry becomes farther from the center of gravity of the rotating drum, so the centrifugal force increases when the rotating drum rotates at the same speed. Therefore, the control unit 510 may measure the centrifugal force to determine the contraction state of the laundry.

In one embodiment, since the weight of the laundry is changed by drying, the control unit 510 may correct the reference value of the centrifugal force used to determine whether or not the laundry is contracted in consideration of the weight of the laundry.

In one embodiment, when it is determined that the laundry is excessively contracted, the control unit 510 may control to lower the temperature of heat supplied by the heating unit 530.

According to an embodiment, the control unit 510 may stop drying and output a notification requesting confirmation of laundry. The notification may be provided using an output means provided in the washing machine 500 or may be provided to a user terminal through a network.

In one embodiment, the control unit 510 may adjust the water temperature during washing.

In one embodiment, the control unit 510 may monitor the color of the washing water using at least one sensor in the washing step.

In one embodiment, the control unit 510 may directly monitor the color of the washing water contained in the fixed drum, or may extract the washing water at a predetermined cycle to monitor the color.

In one embodiment, the control unit 510 may determine that water is generated when the color of the washing water is outside a preset range.

For example, when the washing water becomes black or red, it can be determined that water dripping occurs from the laundry.

In this case, the control unit 510 may control to lower the temperature of the washing water. For example, the control unit 510 may control the cold water to be injected into the fixed drum or to lower the temperature of the newly supplied washing water in a subsequent washing step.

According to an exemplary embodiment, when it is determined that water draining occurs, the controller 510 may drain all of the washing water, stop washing, and provide a notification to the user.

According to an embodiment, the control unit 510 restarts washing by injecting water at a preset temperature (for example, lukewarm water at about 40 degrees Celsius or cold water having a temperature below 40 degrees C) after draining all the washing water. Or, you can rinse the laundry with the injected water.

In one embodiment, the washing machine 500 may include at least one imaging sensor unit for monitoring the color of the washing water, and the imaging sensor unit may be provided inside the rotating drum or the fixed drum to directly monitor the color of the washing water. have.

As another example, the imaging sensor unit may be provided outside the fixed drum, and a washing water sampling unit capable of transferring washing water from the fixed drum to the imaging sensor unit may be further provided.

The washing water sampling unit may extract a portion of the washing water through a pipe, or may include a thin pipe that allows a portion of the washing water to reach the imaging sensor unit using a capillary phenomenon.

In one embodiment, since the soapy water is included in the washing water, it may be difficult to determine the color, and the soap bubble removing unit for removing the soap bubble may be further included in the washing machine.

The soap bubble removing unit may perform a process of mechanically removing the soap bubbles floating on the washing water after stirring the extracted washing water to increase the soap bubbles, or separately extracting the remaining washing water left after the soap bubbles float.
