The present invention relates to an automatic rinsing method of a washing machine having a small drum washing tank, and more particularly, to a method of automatically rinsing a laundry and a small drum washing tank while a laundry is put in a drum body in a small drum washing tank. will be.

In general, a washing machine employing a small drum washing tank for washing laundry while boiling the laundry is provided with a sliding outer door 14 for putting laundry into an upper portion of one side of the body 11 of the general washing machine 10 as shown in FIG. , A small drum including a drum body 13 rotated by a motor, a water supply valve 15 for supplying washing water into the washing tank, and a heater (not shown) for heating the washing water in the washing tank. The washing tank 12 is attached.

As described above, laundry, such as underwear or a diaper, is mainly put into the drum body 13 in the small drum washing tank 12 mounted at the upper end of the body 11 of the general washing machine 10, and the washing water reaches a predetermined level. As the sieve 13 rotates, the heater is automatically operated to wash the laundry while washing the laundry. When washing the laundry while boiling the laundry in this way, the drum body 13 or its outer cover is heated by the heat generated from the heater, and since the drum foam 13 rotates, a considerable amount of foam is generated by the detergent. To remove the laundry put into the drum body 13 to be put into the washing tank or dehydration tank of the general washing machine 10, there was an inconvenience to wait until the drum body 13 cools or until the foam disappears.

Therefore, the present invention has been made to solve the above-mentioned shortcomings, and the present invention aims to provide a method for automatically rinsing laundry and drum bodies by draining water at the same time as washing water in a small drum washing tank. .

In order to achieve the above object, the present invention is a laundry end time determination process for comparing the current remaining time and the set washing end time of washing the laundry after the laundry is put into the small drum washing tank and the washing water reaches the set water level And a first valve driving process of turning on a cold water supply water supply valve and a drain valve if the washing end time remains the same as the time at which the washing end time is determined in the washing end time determination process, and a water supply valve and the first valve driving process. Washing end detection process for detecting whether the washing administration is finished in the state in which the drain valve is on, and the second valve driving process for turning off the water supply valve and the drain valve when the washing administration is finished in the washing end detection process. .

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

Figure 2 is a schematic diagram of the automatic rinsing apparatus according to the present invention, surrounding the data for washing the laundry put into the drum body 13 in the washing tank of the general washing machine 10 or the small drum washing tank 12 for a predetermined time, The data input unit 21 inputs to the system controller 23 for controlling the device, and the data input unit by the system controller 23 which receives the data input through the data input unit 21 and converts the segment drive signal and outputs it. The display unit 22 which displays the data inputted to the 21 to the outside, and the motor 26 in accordance with the signal level output from the output ports P1, P2, P3, P4 of the system controller 23, respectively. ), The operation power supplied to the drain valve 27, the water supply valve 28, and the heater 29 is switched to operate the motor 26, the drain balance 27, the water supply valve 28, and the heater 29, respectively. A switching unit 25 configured as an AC switch to turn on or off, and the system control The signals output from the output ports P1, P2, P3 and P4 of the chuck 23 are inverted so that the triac T1, T2, T3 and T4, which are AC switches in the switching section 25, An inverter unit 24 for supplying the gate terminal, a data input unit 21 for converting AC power supplied through an external line into DC, a power supply unit for supplying an operating voltage to the display unit 22, the system controller 23, and the like ( 20).

Referring to the flow chart shown in Figure 3 the operation of the automatic rinsing device having the configuration as described above are as follows.

After the laundry is put into the drum body 13 in the small drum washing tank 12 shown in FIG. 1, a user inputs data corresponding to the washing administration through the data input unit 21 shown in FIG. The controller 23 displays the input data on the display unit 22 and outputs a high signal to the output port P3.

When the high signal is output from the output port P3 of the system controller 23, the high signal is amplified by the current in the inverter IN3 in the inverter unit 24 and the signal level is inverted to the gate of the triac T3. Supplied to the terminal.

Accordingly, since the triac T3 is turned on, the water supply valve 28 for supplying the cold water is turned on as in step S1 of FIG. 3 so that the washing water is supplied into the small drum washing tank 12. When the water supply valve 28 is turned on and the washing water is supplied as in step S1, step S2 detects whether the washing water reaches the set water level. For example, if the washing water does not reach the set water level, the water supply valve continues in step S1. On the contrary, when the wash water reaches the set water level, the triac T3 and the water supply valve 28 are turned off, respectively, because the output port P3 of the system controller 23 outputs a low signal. The wash water supplied to the washing tank 12 is blocked. When the washing water reaches the set water level, the high signal is output from the output ports P1 and P4 of the system controller 23, so that the motor 26 and the heater 29 are operated so that the drum body 13 as in step S3. The washing administration is performed while the laundry put into the bowl is boiled.

In the process of washing the laundry according to the washing administration as in step S3, in step S4, it is determined whether the current remaining time is the T minutes before the set washing end time during the washing of the laundry. If it is longer than this T minutes, washing continues as in step S3. On the contrary, if the current time remaining is T minutes before the washing time is set, the system controller 23 sends a high signal to the output ports P3 and P2. The water supply valve 28 and the drain valve 27 are turned on and drained while supplying water to the washing tank 13. Therefore, the washing water heated by the heater 29 is drained through the drain hole, and the small drum washing tank 12 heated by the cold water newly supplied begins to cool down gradually. At this time, the system controller 25 outputs a low signal to the output port P4 to cut off the power supplied to the heater 29.

After performing the step S6, the system controller 23 determines whether the washing administration time is completed in step S7. If the washing end time is not the same, the system controller 23 continues to turn on the water supply valve 28 and the drain valve 27, and ends the washing. If it is time, the water supply valve 27 is turned off like step S8. When the water supply valve 27 is turned off at the step S8, the drain valve 27 is turned off at the step S9. Therefore, the small drum washing tank is automatically rinsed for 2 minutes.

The present invention, which operates as described above, automatically cools the heated washing tank and cools the foam by detergents, since water and drainage are automatically performed before the washing administration to wash while boiling the laundry put into the drum body in the small drum washing tank. Since it drains, there is an effect that can easily take out the laundry put into the drum body.
