The invention relates to a drum type washing machine for improving washing performance and preventing black spots on clothes. Background of the Invention A conventional washing machine is a method of controlling the washing process in a high-concentration state in order to improve the washing performance, and is disclosed in Japanese Laid-Open Patent Publication No. 2000-342887 (hereinafter referred to as "Patent Document No."). Hereinafter, the operation of the conventional washing machine described in the patent document will be described with reference to the drawings. Figure 6 is a flow chart of the operation of the conventional washing machine. Figure 7 is a front view showing the water setting button of the same washing machine. Fig. 8 and Fig. 83 are views showing an example of a display lamp indicating the washing amount of the same washing machine. As shown in Fig. 6, first, when the user inputs power, the washing machine starts. Next, it is judged whether or not the user selects the high-concentration order by the operation program selection button or the like (step Si〇i). Further, when the user selects the enthalpy concentration program (YES in step S1), the amount of water used for the display lamp 35a shown in Fig. 7 is displayed, and the display is displayed on the display lamp 4 shown in Fig. 8A or Fig. 8B. Add a standard of 4% wash dose (step S102). The user can add the lotion or the like to the inner tank according to the amount of the washing agent to be displayed, and the amount of water can be changed by the water amount setting button 35 shown in Fig. 7 to change the salt. JtB Temple, in Patent Document 1, the system will wash The dose is shown to be greater than the amount required for the standard run 3 201229351 procedure and the feed water volume is reduced compared to the standard operating procedure. For example, when the amount of water supplied to the water is 30 liters, the washing dose is shown as 60 grams compared to the washing. This is because in the standard washing procedure, the amount is set to 3 kg, that is, the water volume is 39 liters and the washing dose is gram. In the case of the concentration program, the concentration of the lotion is about 3 times. The washing dose is displayed, and the lotion is put into the inner tank or the like, the washing is started, and the water is supplied to the set water supply amount (step sl3). When the water supply is finished, the washing process is moved to the washing course (step S111). The scheduled laundry time (step si (7) when the laundry time passes and ends the laundry journey (step sn2 is), moves to the less than one stroke, such as washing and cleaning the other side - when 'no laundry time (step: two no)' return The laundry stroke (step sm). Further, the user does not select the high concentration material (No in step S1G1), and judges whether or not the immersion high concentration material is selected (step s just). Correction, when the high enthalpy program is not selected (Step of action, perform another (4) After ordering the laundry stroke (step SU3) and the high-concentration program phase step _), first, the user according to the displayed ζ" display; " washing dose (step S Gang start Washing action, water supply - "Inject the lotion into the inner tank, etc. during the period. And at the end of the water supply, ;; =: = 岣 ' (10), then search the mash (step S1 〇 7) and do not mix (step S107). At this time, when the immersion operation is performed in the water tank, the movement is shifted to the following immersion squeezing 8 (step S1G9), and it is judged that 'stop (step S108) and d to no end (step S110). Further, 201229351 returns to the sink. When the rotation stop immersion operation is not completed (NO in step S110), (step S108) and stirring B (step S1 〇 9). Next, 'dip silk is used as a knot tree ((4) _ is), (4) high concentration program In the same manner, after the laundry stroke (step sui), the conventional washing machine selects the cardio-agricultural program by the above-mentioned control method, and the amount of the lotion is more than the standard operating procedure. Moreover, the amount of water supplied to the water is reduced and washed, thereby improving the cleaning effect, preventing the black spots of the clothes, and the high quality laundry effect of the thief. Moreover, the conventional washing machine is a high concentration program for preventing black spots on the clothes. When washing, the predetermined amount is washed for a smaller amount of water than the prescribed amount of water. The type is based on the strong suction of the mixing tank in the sink (inner tank). At this time, the tank (outer tank) that is wrapped in the tank is supported by the basket in a freely oscillating manner, so it is strong in the inner tank. When the stirring clothes are pulled, the entire outer groove will be shaken vigorously, the vibration will become large, and noise will be generated due to vibration. Further, in the worst case, there is a problem that the outer groove collides with the casing. Further, in the patent document, in the embodiment Although the vertical type automatic washing machine is taken as an example, the drum type washing machine also has the same problem. In order to avoid the above problem, the following method is proposed, that is, the prescribed amount of water is put into a prescribed amount of clothes, And the user puts the lotion into the general 2 times '俾 to increase the lotion concentration. However, even if the amount of the lotion is doubled, it is impossible to completely prevent the stain from reattaching to the clothes. Further, as the amount of the lotion increases, there is also a problem that the burden on the economy increases. Therefore, in recent years, a washing machine including a lotion automatic input device that automatically puts a lotion into a water tank of a washing machine has been put into practical use. Currently, the automatic charging device for liquid detergent 201229351 has become mainstream because of its ease of operation.

Further, in the case of the mode of preventing the high-quality laundry performance program (black spot prevention program) for clothing black spots in the present embodiment, the water level of the low water level or the middle water level is automatically set, and the water level is displayed on the water level display portion 84b. Therefore, the control of the mode for selecting a high-quality laundry effect program for preventing black spots on clothing is described below using Figs. 4A and 43. Fig. 4A and Fig. 4B are flow diagrams showing the control of the garment stroke to the dehydration stroke in the mode of the high quality laundry performance program of the same drum type washing machine. As shown in Fig. 4A, first, by operating the liquid lotion of the wheel setting unit 83 of the display unit 74 to automatically inject 8 3 g, it is determined whether or not the liquid lotion is automatically charged (step Si). Next, when the liquid lotion is automatically input (YES in step S1), it is judged whether or not 13 201229351 or not the mode of the high-quality laundry effect program 84a is selected by the program button 83c of the input setting unit 83 of the operation display unit 74 (step S2). Also, when the high-quality laundry effect program 8 is selected as the mode (the step is illusory), the washing in the mode of the high-quality laundry effect program starts. Next, the cloth amount detecting unit 91 shown in Fig. 2 detects the amount of cloth or the like to be put into the clothes (step S3), and the control unit 88 sets the water level corresponding to the detected cloth amount (the low water level in the case of the high-quality laundry effect program) Or the middle water level) is displayed on the water level display unit 84b (step S4). At the same time, the washing amount of the general lotion concentration corresponding to the amount of water in the detected water level is displayed on the electronic display portion 84c in the amount (e.g., the lotion cup) (step S4). For example, when the cloth volume is 45 kg and the set water level is automatically set to the middle water level, the standard standard washing dose is 0.8 cups for the lotion cup. Then, the air pump 96 of the automatic detergent dispensing device 95 automatically introduces a predetermined amount of the liquid detergent corresponding to the lotion cup 8 of the electronic display portion 84c by the lotion tank 95b (step S5). Thereafter, the control unit 88 controls the water supply valve 85 via the load driving unit 87 to start supplying water to the water tank 52 (step S6). Then, the predetermined amount of the water supply to the automatically set water level is turned on at the end of the water supply (pipping π).

At this time, in the drain, the water in the water tank 52 is completely drained, and after the water level detecting unit 94 shown in Fig. 2 detects that there is no water, the control unit 88 closes the drain valve 59. By this drainage, a certain degree of dirt which is peeled off by the clothes is discharged to the outside of the drum type washing machine. Then, by the air pump 96 of the automatic detergent supply device 95, a predetermined amount of the liquid detergent is automatically supplied again from the detergent tank 95b (step S9). Namely, after the pre-washing stroke, the amount of water to be drained and the amount of the lotion are set (imagined) to reach a predetermined concentration by the lotion in the step S9 of Fig. 4A and the step S1 of the step SB. Thereafter, as shown in Fig. 4B, the water supply to the same water level as that of step S6 is performed (step S10). The subsequent operation will be described based on Fig. 4B. And the laundry disturbance of the main washing course is started (step S11). Next, after the laundry is stirred in the main washing course, the washing (1) stroke of the next stroke is performed. In the cleaning (1) stroke, first, the control unit 88 starts the drain valve 59 via the load driving unit 87, and drains the washing water in the water tank 52 (step S12). Thereafter, the centrifugal force of the clothes is applied to dehydrate the water from the clothes (step S13). Thereafter, the control unit 88 controls the water supply valve 85 via the load driving unit 87 to supply water to the water level of the laundry stroke. Then, the control unit a drives the motor 54 via the negative drive unit 87 to rotate the rotary drum 53, and starts washing and agitating the detergent liquid from the clothes (step S14). After that, after the (1) stroke is washed, the final cleaning step is washed (2). In the cleaning (2) stroke, the control unit 88 15 201229351 opens the drain valve 59' to discharge the washing water in the water tank 52 via the load driving unit 87 (step S15). Thereafter, the centrifugal force of the clothes is applied to dehydrate the water from the middle of the clothes (step S16). Next, the control unit 88 controls the water supply valve 85 via the load driving unit 87 to supply water to the water level of the laundry stroke. Then, the control unit 88 drives the motor 54 via the load driving unit 87 to rotate the rotary drum 53 to start washing and agitating the washing liquid from the clothes (step S17). Next, after the completion of the cleaning (2), the dehydration step is performed (step S18). In the dehydration process, first, the drain valve 59 is opened to discharge the water in the water tank 52, and the drive motor 54 rotates the rotary drum 53 at a high speed to give the centrifugal force of the clothes, thereby separating the moisture from the clothes. The following describes the control in the case where the liquid detergent is not automatically selected in the step S1. That is, as shown in Fig. 4A, when the liquid detergent is not automatically selected (NO in step S1), the washing machine is operated by a program other than the mode selected for the high-quality laundry performance program (generally, the high quality cannot be selected in advance). The mode of the laundry effect program) (step S23). At this time, first, the cloth amount detecting unit 91 shown in FIG. 2 detects the amount of the cloth to be fed (step S24), and the control unit 88 displays the water level corresponding to the detected amount of water on the water level display unit 84b (step S25). . Simultaneously, the washing amount of the general lotion concentration corresponding to the amount of water to be detected is displayed on the electronic display portion 84c such as a cup (cup) of the lotion cup. The user inputs the washing amount displayed on the electronic display unit 84c (step S26). Thereafter, the control unit 88 controls the water supply valve 85 via the load driving unit 87, and starts water supply to the water tank 52 as shown in Fig. 4B (step sl), and executes the aforementioned

S 16 201229351 The steps from step su to step S18 are performed to perform the washing of the main washing course. Further, similarly, the control in the case where the mode of the high-quality laundry performance program is not selected in the step S2 is as follows. That is, as shown in Fig. 4A®, the model of the high-quality laundry performance program (No. 4S2) is selected, and the program of the mode other than the high-quality laundry program is selected (step S19)' and the washing machine is operated. At this time, first, the cloth amount detecting unit 91 shown in the figure detects the amount of the person to be thrown (step illusion), and the control unit 88 displays the water level corresponding to the detected amount in the water level display unit, step S21). At the same time, the washing amount of the general lotion concentration corresponding to the amount of water in the detected water level is displayed on the electronic display portion 84c in the amount of the lotion cup (cup) (step S21). Moreover, the air lotion 96' is automatically put into the device by the lotion to display the amount of the lotion cup which is called the amount of the lotion cup in the electronic display unit. The lotion is automatically cast by the lotion tank 95. The person goes to the water tank 5 2 (step S22). Thereafter, the control unit 88 controls the water supply valve 85 via the load driving unit 87, and starts water supply to the water tank 52 as shown in FIG. 4B (step si()), and performs the operations of steps S11 to S18 described above to start the main operation. Wash your knees. As described above, according to the embodiment, in the mode of preventing the high-quality laundry performance program (black spot prevention program) for clothing black spots, first, the detergent water containing the dirt peeled off by the clothes by the pre-washing is drained. The liquid lotion is again automatically introduced into the water tank 52 by the air pump 96. Further, the lotion and the newly-added lotion are added together, and the lotion is washed at a predetermined concentration to wash the main washing step. In this way, it is possible to realize a drum type film that can prevent the black spots of clothing and wash it with high quality laundry effect. Further, since the pre-washing stroke and the main washing stroke are performed at a normal water level, it is possible to suppress the vibration of the water tank from being drastic and the noise generated due to the rotation of the rotating cylinder axis. Thereby, a drum type washing machine in which the vibration performance is not weakened can be realized. Further, according to the present embodiment, in the drain of the step S8 of the fourth embodiment, the dirt which is peeled off by the clothes is discharged to the outside of the washing machine, but the remaining laundry is left in the clothes in the rotating drum and the lotion absorbed into the clothes is left. . Therefore, if the amount of cloth is 4.5 kg, the liquid washing dose compared with the generally required lotion concentration is 0.8 cups of the lotion cup, and the liquid washing amount automatically input in step S9 takes into account the aforementioned absorption to the clothes and remains. The amount of the lotion, which is less than 0.8 cups in the pre-washing period, such as 0.7 cups to 0.6 cups, is also sufficient. That is, even if a liquid washing dose of a lottery concentration which is more generally required is added, the lotion concentration can be increased more than usual. Thereby, washing is carried out without investing too much detergent. As a result, the environmental impact due to excessive elution of the lotion can be reduced. Further, it is possible to realize a drum type washing machine which can improve washing performance and prevent black spots on clothing, and washes with high quality laundry effect. Further, according to the present embodiment, by draining the dirt which flows out once in the pre-washing stroke, it is possible to prevent the dirt which has flowed out into the washing water during the pre-washing stroke from adhering to the clothes again. Thereby, it is possible to wash with a high concentration of the lotion according to the water level of the cloth. Further, according to the present embodiment, by draining the dirt which flows out once in the pre-washing stroke, the amount of washing to be applied to the main washing stroke can be made smaller than the amount of washing in the pre-washing stroke. As a result, it is possible to realize a drum type washing machine as described below, that is, even if the amount of the lotion used is small, the washing performance can be improved.

18 S 201229351 Line washing, and the environment is better because no excessive lotion is needed. (Embodiment 2) Hereinafter, a drum type washing machine in Embodiment 2 of the present invention will be described with reference to the drawings. Fig. 5A and Fig. 5B are flowcharts showing the control of the washing stroke to the dehydration stroke in the mode of the high quality laundry performance program of the drum type washing machine in the second embodiment of the present invention. The drum type washing machine of the present embodiment differs from the first embodiment in that the dewatering stroke (step S101) is set after the draining in step S8 in the washing stroke to the dehydrating stroke in the mode of the high-quality laundry performance program. Since other controls and operations are the same as those in the first embodiment, the description will be omitted. Herein, the dehydration process will be described in detail below (step S101), and the other strokes are the same as those in the first embodiment, and therefore will be briefly described. That is, as shown in Fig. 5A, first, when the liquid detergent is automatically input (YES in step S1) and the mode of the high-quality laundry performance program 84a is selected (step S2), the washing of the high-quality laundry program starts. . Then, the cloth amount detecting unit 91 shown in Fig. 2 detects the amount of cloth to be fed (step S3)' and displays the water level corresponding to the detected amount on the water level display portion 84b (step S4). At the same time, the washing amount of the lotion concentration corresponding to the amount of water in the detected water level is displayed on the electronic display unit 84c (step S4). Thereafter, a predetermined amount of the liquid detergent displayed on the electronic display unit 84c is automatically charged by the automatic detergent input device 95 (step S5). Next, the control unit 88 controls the water supply valve 85 to start the supply of water into the water tank 52 (step S6), and starts stirring the water supply (step S7). Thereby, the dissolution of the washing liquid of the 201229351 detergent is promoted, and the clothes are stirred to start the pre-washing stroke. & Next, when the stain of the clothing is dropped to some extent during the pre-washing process, the drain valve 59 is started, and the drain water in the water tank 52 is drained (: after/after the rotating drum 53 is rotated at a high speed, The dehydration process is carried out (step _. Thereby, the dirt remaining inside the clothing can be peeled off and discharged, and discharged out of the machine of the drum type washing machine. Next, the predetermined amount of liquid is automatically input again by the automatic detergent input device 95. The lotion (step S9). Thereafter, as shown in Fig. 5B, the water is supplied to the same water level as step 6 (step 10), and the laundry agitation of the main washing course is started (step S11). After the laundry is stirred, the drainage is carried out in sequence (steps)

Sl2), intermediate dehydration (step S13), washing and stirring (step S14), and performing a washing/month (1) stroke. Thereafter, after the washing (1) stroke, the final washing operation consisting of drainage (step S15), intermediate dehydration (step S16), and washing and stirring (step S17) is performed, that is, the cleaning (2) stroke is performed. And washing (2) after the end of the stroke, the dehydration step is performed (step S18). Further, the control in the case where the liquid lotion in the step S1 is not automatically input and the control in the case where the mode of the high-quality laundry effect program in the step S2 are not selected are the same as those in the embodiment, and thus the description thereof is omitted. As described above, according to the embodiment, the mode of the high-quality laundry effect program (black spot prevention program) for preventing the black spots of clothing is first, and the washing water containing the dirt which is removed from the pre-washing line is almost all Drain,

S 20 201229351 And even the dirt remaining inside the clothes is forcibly peeled off and discharged to the outside of the drum type washing machine. Thereafter, the liquid lotion is automatically introduced again, and a part of the lotion contained in the clothes is combined with the newly-added lotion, and the lotion having a predetermined concentration is slightly doubled, and the washing is performed in the main washing course. Thereby, it is possible to realize a drum type washing machine which further prevents dark spots of clothing and washes the laundry with high quality laundry effect. Further, since the pre-washing stroke and the main washing stroke are performed at a normal water level, it is possible to suppress the vibration of the water tank from being enlarged and the noise generated by the rotation of the rotating drum axis. Thereby, a drum type washing machine in which the vibration performance is not lowered can be realized. Further, according to the present embodiment, by performing the dehydration step in step S101 of FIG. 5A, almost all of the washing water contained in the pre-washing stroke from the clothes is drained, and even the dirt remaining inside the clothes is allowed to be drained. It is also forcibly peeled off and discharged to the outside of the drum type washing machine. In this case, since the main stain remaining in the clothes can be removed, when a liquid detergent is automatically added and washed again, a small amount of the lotion remaining in the clothes such as the clothes after dehydration is washed in the main wash. The amount of lotion required for the stroke is even less than the amount of 0.8 cups invested in the pre-wash stroke, such as 0.4 cups to 0.5 cups. That is, the washing amount can be performed with sufficient washing performance in a vertical or low washing dose. Thereby, the washing is carried out without injecting too much detergent. As a result, the environmental impact caused by the excessive elution of the lotion can be further reduced. Further, it is possible to realize a drum type washing machine which can improve the washing performance and prevent the black spots of the clothes, and then wash the clothes with high quality laundry effect. Further, according to the present embodiment, it is possible to suppress the contamination again by forcibly dehydrating and discharging the dirt which flows out once in the pre-washing stroke. 21 201229351 Attached to clothing.
