Abstract

PURPOSE: An automatic laundry drying stand is provided to dry the large amount of the laundry in the small area, and to use conveniently without care in going out by automatically moving the laundry drying stand indoors and outdoors through a sensor according to weather condition. CONSTITUTION: An automatic laundry drying stand is composed of a power unit(10); an operation unit(20); a sensor unit(30) detecting by combining values of sensors; a comparison unit(40) comparing the detected values from the sensor unit with the values corresponding to weather change; a control unit(50) controlling the output from the sensor unit or the comparison unit; and a motor driving unit(60) actuating the motor according to the signals from the control unit. The automatic laundry drying stand is moved out of a veranda, and moved into the veranda by actuating the motor driving unit according to weather condition.

Description

Automatic Clothes Dryer {AUTOMATIC LAUNDRY DRYING STAND}

The present invention relates to an automatic laundry drying machine, and more particularly, to an automatic laundry drying machine that operates while the drying stand moves back and forth indoors and out through a sensor according to weather conditions.

In general, the known automatic laundry dryer has a remote control that can be controlled wirelessly from a remote location, and consists of a structure that rolls a drying rod between folding folding bars provided under a control box operating by receiving a button signal of the remote controller. It is known that a folding box including a drying rod is raised, lowered or stopped as a button is pressed, and a control box is provided with a fan for blowing heated wind (hot air) to quickly dry laundry on the drying rod.

However, such automatic laundry drying racks are widely used in apartment verandas these days, but when the shade of the apartment veranda is not well dried, the ventilation is not easy, so the laundry is wet.

The present invention is to improve the problems described above, an object of the present invention is to provide an automatic laundry drying rack that can hang clothes outside the apartment porch, and can automatically enter the inside of the apartment porch when the weather conditions are not good.

Figure 2 shows a state diagram in which the automatic laundry drying rack according to the present invention outside the apartment veranda,

Figure 3 shows a state diagram when the automatic laundry drying rack according to the present invention is combined.

Automatic laundry drying rack according to the present invention for achieving this object is a sensor unit 30 for detecting the combined value of each sensor; A comparison unit 40 comparing the detected value of the sensor unit 30 with a value according to a change in weather; A controller 50 for controlling output values from the sensor unit 30 and the comparison unit 40; And a motor driver 60 for driving the motor by receiving the signal from the controller 50.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 shows a block diagram of an automatic laundry dryer according to the present invention, Figure 2 shows a state diagram of the automatic laundry drying rack according to the present invention outside the apartment porch, Figure 3 is an automatic laundry drying rack according to the present invention Show the state diagram when combined.

Referring to FIG. 1, the automatic laundry dryer 1 according to the present invention includes a power supply unit 10, an operation unit 20, a sensor unit 30, a comparison unit 40, a control unit 50, and a motor driving unit 60. Consists of

The power supply unit 10 uses a phase voltage of 220V, and operates the voltage of the sensor to a DC voltage by using an AC input as a DC voltage.

The operation unit 20 operates the automatic laundry dryer 1 automatically and manually, takes the operation of the sensor in the automatic operation, and operates in the manual operation in the event of an error in the automatic operation.

The sensor unit 30 receives a change in an analog signal and combines values of an illuminance sensor, a rain sensor, a humidity sensor, a proximity sensor, and an ozone sensor that are externally installed. Here, for each sensor, the light sensor detects dark and bright values, the rain sensor detects rain on the rain sensor surface, and the humidity sensor sets an appropriate humidity reference value. It detects high humidity and low humidity, and proximity sensor detects human approach because it is dangerous when the automatic clothes dryer (1) enters the inside, and ozone sensor is a factor that blackens laundry due to external carbon monoxide. It is responsible for detecting ozone.

The comparator 40 operates each sensor to enter the value of each sensor of the sensor unit 30 into the input terminal of the microprocessor, and serves to compare the sensor value and the value according to the change of weather.

The controller 50 transmits the analog and digital values obtained through the sensor unit 30 and the comparison unit 40 to the motor driver 60 through an input terminal of the microprocessor. The input value generates a drive signal for controlling the speed and direction of the DC motor, and reduces the output in half by the detection signal from the overcurrent detection to prevent the overcurrent as well as to detect the error by the hardware. It serves to stop.

The motor driver 60 enables forward rotation, reverse rotation and accelerated braking to drive the DC motor. Here, it is preferable to use a quadrant field effect transistor chopper circuit for forward rotation, reverse rotation and accelerated braking.

The present invention configured as described above will be described with reference to FIGS. 1 to 3 as follows.

First, a user who uses the automatic laundry dryer 1 washes clothes and then washes the laundry inside the apartment veranda.

Then, the user automatically operates the operation unit 20 to send the automatic laundry dryer 1 outside the apartment porch. On the contrary, when there is a change in weather, the sensor unit 30 detects the change, compares the detected value with a set value in the comparison unit 40, and then controls the compared value in the control unit 50. The automatic laundry dryer 1 may enter the interior of the apartment porch by operating the motor driver 60.

On the other hand, the above-described automatic laundry dryer 1 may be used manually according to the user's convenience.

Although the invention is shown in the accompanying drawings and described in the description, it is to be understood that the invention is not to be limited to the described embodiments, but that many rearrangements, modifications are made without departing from the spirit of the invention as set forth and defined by the following claims. And it can be understood that it can be replaced.

As described above, the automatic laundry drying rack according to the present invention can dry a large amount of laundry in a narrow space using sunlight, and the laundry does not get wet, and there is an effect of not having to worry about the laundry even when going out.
