At this time, the side of the washing water discharged at the end of the circulation passage 170 is installed to face the inner wall surface of the drum 130 through the rim 112.

In particular, the end of the circulation passage 170 is more preferably connected to the steam supply pipe 220 as in the accompanying drawings in the embodiment of the present invention.

Hereinafter, a washing method according to a preferred embodiment of the present invention using the above-described drum type washing machine will be described with reference to a flowchart of FIG. 5 and a state diagram of FIGS. 6 to 8.

First, when a request for performing a washing by a user is made, a controller (not shown) constituting the washing apparatus supplies water to the tub 120 (S110).

At this time, the wash water passes through the detergent box 114 provided on the pipeline of the wash water supply pipe 113 while water is supplied through the wash water supply pipe 113.

In the detergent box 114, since a predetermined amount of detergent is stored, the wash water supplied into the tub 120 contains detergent stored in the detergent box 114.

In particular, in the water supply process of the wash water as described above, the wash water is controlled to achieve a highly concentrated state.

This, as shown in Figure 6 attached to the water level of the wash water is a low level compared to the level of the wash water is set in accordance with the amount of the laundry, the water level is higher than the bottom surface of the drum 130, in particular, for washing water The heater 122 can be made to achieve a level that can be submerged.

At this time, the water level of the wash water to be supplied is most preferably such that the level of the bottom surface of the drum 130 is locked, that is, the level ("first water level") that the laundry in the drum 130 is wet. Do.

Then, when the above-described water supply process is completed, the drum 130 is driven to perform washing (hereinafter, referred to as "highly concentrated washing") with the water in the highly concentrated washing water (S120).

The highly concentrated laundry is a series of processes to maximize the laundry effect.

In other words, the detergent, which is one of the biggest factors that influence the washing performance, is able to obtain excellent washing performance by the above-described highly concentrated washing, considering that the higher the concentration, the better the washing performance.

At this time, the process of the highly concentrated washing through the driving of the drum 130 may be controlled to proceed simultaneously with the water supply process of the above-described wash water.

In addition, at this time, it is more preferable that the control (S130) to pump the wash water in the tub 120 through the control of the circulation pump 160 to circulate back into the drum 130 through the circulation flow path 170.

This is to allow even washing of the entire laundry by allowing the washing water in a highly concentrated state to be sprayed toward the laundry inside the drum 130 while the highly concentrated washing is in progress.

Of course, the circulating process of the wash water may also be controlled to proceed simultaneously with the water supply process of the wash water, or may be controlled so that both the water supply process, the highly concentrated washing process, and the circulating process of the wash water proceed simultaneously.

On the other hand, during the above-described high-concentration washing process is carried out by spraying a high temperature steam into the drum 130 through the control of the steam supply may be controlled so that the atmosphere inside the drum 130 can achieve the most effective temperature for washing performance have.

In other words, by using the above-described high-temperature steam to the drum inside to achieve the temperature (approximately 40 ℃ to 60 ℃) to obtain the most efficient washing performance by activation of the detergent to improve the washing effect.

Of course, the process of providing the steam may be controlled to proceed simultaneously with the water supply process of the wash water, may be controlled to proceed simultaneously with the circulation process of the wash water, or may be controlled so that all of the processes proceed simultaneously.

Then, when the above-described highly concentrated washing is performed for a predetermined time, hot steam is injected into the drum 130 through the control of the steam supply unit (S140).

At this time, the reason for spraying the high temperature steam is to increase the temperature inside the drum 130 to the sterilization temperature to achieve the sterilization of various bacteria contained in the laundry.

Of course, even at this time, the drum 130 can be continuously driven so that the sterilized washing in a highly concentrated state continues (S150). Its state is as shown in Figure 7 attached.

In particular, the spraying process of the steam as described above may be controlled to be continuously performed during the highly concentrated sterilization washing operation, in this case, the amount of steam provided to the inside of the drum 130 is excessively large, or the drum The temperature inside the 130 may rise excessively, which may cause a problem that causes power waste.

Accordingly, the spraying process of the steam is most preferably controlled to proceed only for a set time in a set temperature range.

In this case, the set temperature range is a temperature range in which bacteria can be sterilized as described above, and the set time is a time at which sterilization time can be obtained as much as possible.

In addition, the method of controlling the injection of steam to proceed only during the time set in the set temperature range is performed by controlling to repeat the operation and stop operation of the steam supply.

That is, by selectively turning on and off the power supply for heat generation control of the heat generating unit 210 to maintain the inside of the drum 130 in the set temperature range.

At this time, the checking of the temperature is performed by reading the signal sensed by the temperature sensor 150.

Therefore, high concentration washing and sterilization washing are sequentially performed by the above-described series of processes.

When the highly concentrated washing and sterilizing washing process is completed by the above-described series of processes, the washing water is additionally supplied into the tub 120 (S160).

In this case, the washing water supplied into the tub 120 does not contain detergent, and the additional washing water is provided until a predetermined level (“second water level”) can be achieved according to the quantity of laundry. Watering. Its state is as shown in Figure 8 attached.

This process is a process for preventing the deterioration of the laundry due to long-term reaction with the highly concentrated detergent by diluting the highly concentrated detergent contained in the laundry and washing the highly concentrated detergent contained in the laundry. to be.

In addition, in the above-described process, the drum 130 is controlled to be continuously driven.

Therefore, the detergent of the high concentration is more smoothly removed from the laundry while the diluted washing proceeds (S170).

In particular, when considering that the highly concentrated detergent contains a variety of contaminants separated from the laundry, the various contaminants are also smoothly removed from the laundry.

On the other hand, considering that the temperature of the wash water to be additionally watered in the dilution washing process through the additional water supply of the wash water is approximately 30 ℃ or less due to mixing with the existing wash water is the temperature of the overall wash water to the washing performance Preferred temperatures may drop below 40 ° C, for example.

Therefore, in the dilution washing process through the additional water supply of the wash water, the washing water heater 122 in the tub 120 is heated to heat the wash water in the tub 120, so that the temperature of the entire wash water is about 40 ° C. or more. Most preferably.

Of course, the temperature inside the drum 130 may be controlled to achieve a temperature that may improve washing performance by spraying hot steam into the drum 130 without directly heating the wash water.

In particular, when such a series of processes, that is, the dilution washing process through the additional water supply of the washing water, the washing water in the tub 120 is pumped through the control of the circulation pump 160 to re-drum through the circulation passage 170. It is more preferable to control to circulate inside 130.

This is to ensure that the highly concentrated detergent contained in the laundry can be more smoothly removed, and at the same time, the entire laundry can be evenly washed.

As a result, when the above-described dilution washing process is performed for a predetermined time, the washing process for the laundry is completed, the heat generation of the washing water heater 122, the driving of the circulation pump 160, and the driving of the drum 130 are stopped.

Then, when the above-described series of washing strokes is completed, the washing water inside the tub 120 is drained through the drainage passage 121, and at least one or more rinsing strokes are continuously performed by supplying new washing water.

Of course, before performing the rinsing stroke after draining the wash water, it is preferable to further include a series of processes for dewatering the laundry by rotating the drum 130 at high speed.

As described above, the washing method of the laundry apparatus according to the embodiment of the present invention has the effect that the washing stroke of the laundry is possible with a small amount of washing water consumption and low power consumption.

In particular, the washing method of the present invention has the effect that it is possible to obtain a sterilization effect as well as to improve the washing performance by the sterilization of the laundry by using a high temperature steam.

In addition, the washing method of the present invention has the effect of being able to further improve the washing performance by performing dilution washing after performing the washing using a detergent of high concentration as described above.
