Field of the Invention The present invention relates to a washing machine for washing and washing laundry in a rotating drum having a rotating central axis in a horizontal direction or a 5-inclined direction. And dehydration, at the same time, it is possible to wash foreign matter such as lotion or mildew which adheres to the inner and outer surfaces of the rotating drum and the inner wall surface of the water tank containing the rotating drum. [Prior Art 3 10] Heretofore, a lotion composition for washing an outer wall attached to a washing tank having a rotating center axis in a vertical direction or an inner wall of a tank other than a washing tank has been combined with metal ions in tap water. A method of causing a foreign matter 15 such as black mold spots which acts on the metal soap by the microorganisms contained in the metal soap or the wash strip (for example, see Patent Document 1). In the conventional example 1, since the rotating shaft of the washing tub is provided in the vertical direction, water is supplied into the washing tank to a predetermined water level, and the detergent is supplied, and the stirring blade is rotated for a predetermined time to prepare Washing solution. Next, a soaking stroke for intermittently rotating the washing tub is performed, and the washing liquid is spread over the outer wall of the washing 20 tank or the inner wall of the outer tank, and the soaking stroke is performed for a predetermined time, so that the washing liquid sufficiently acts on the foreign matter. To remove foreign matter. Then, the stirring blade is rotated again, and the washing liquid in the washing tub is sent from the pump chamber to the thread filter through the circulating water passage, and the foreign matter contained in the washing liquid is recovered to the thread filter. In addition, a rotary drum type washing machine that washes, washes, and dehydrates the laundry in a rotating roll having a central axis of rotation in the horizontal direction or the oblique direction (see, for example, Patent Document 2: Conventional Example 2) . [Patent Document 1] Japanese Patent Laid-Open Publication No. 2 (8) No. 2-248295 [Patent Document 2] 曰 This Patent Publication No. 1 〇 〇 〇 〇 〇 〇 [ [ [ [ [ [ [ [ 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明 发明In the washing machine with the rotating central axis in the vertical direction, by supplying water into the washing tank to the predetermined water level and making the washing, the outer tank of the ship (4) is fully soaked for 4/night. By the rotation of the washing tank and the stirring blade, the foreign matter attached to the inner wall of the outer wall and the outer tank can be sufficiently washed. 15 Rotating Γ t The above-mentioned f example 2 'In a drum-type washing machine having an axis in a horizontal direction or an oblique direction, water can only be supplied to a part of the inner wall surface of the rotating water tank of the rotating drum; The washing method of the foreign matter to which W is attached, and even if the washing method of the example L is applied, the washing effect cannot be sufficiently obtained. In view of the above-mentioned conventional problems, the present invention is applied to a washing machine which is attached to the inner and outer surfaces of the rotating drum and the (four) surface of the water tank by the material side: == the cleaning effect of the incineration. d and each of the temples are different for the above purposes, the washings associated with the present invention are the same as '(4) for storage washing, and have a central axis of rotation in the horizontal direction or inclined side 2 1261638; the sink is filled with the aforementioned rotating drum, and Removably supported by the washing machine body; the motor can drive the rotating drum; the water supply device supplies water to the water tank; the input setting device is used to set the operation of the washing machine; and the control device is used for The control of the washing operation set by the fifth input setting device and the control of the water supply device and the motor, and the control device controls the water supply device to supply water to the unloaded state in which the washing drum has no laundry. After the water tank reaches the set water level, the motor is controlled to perform a combination of the following strokes for a plurality of times within the set time, the strokes including: the first washing 10 strokes, rotating the rotating drum at the first set rotating speed; the second washing a stroke, the rotation drum is rotated at a second set rotation speed, and the second set rotation speed is changed from the first setting And a high speed circulating water system may be generated between the surface of the water tub and the inner wall surface of the outside of the rotating drum; rotating and stopping stroke, so that the rotation of the drum stops rotating. According to this configuration, the inner and outer surfaces of the rotary drum can be washed by the first washing stroke in which the rotary drum is rotated at the first set number of revolutions (low speed, e.g., 35 r/min). Further, by the second washing stroke in which the rotary drum is rotated at the second set rotation speed (high rotation speed, for example, 140 r/min), the outer surface 20 of the rotary drum is rotated by the friction and centrifugal force generated when the rotary drum rotates. A circulating water flow is generated between the inner wall surfaces of the water tank, and the inner wall surface of the water tank can be washed by the generated circulating water flow. In particular, in the upper portion of the rotating drum and the water tank, there are particles of the lotion or sputum which are scattered during the washing, and the washing water cannot be reached, and the washing is hardly possible.

Torque. 5 The laundry amount detecting device 30 is for detecting the amount of the laundry in the rotary drum 1, and detecting it based on the 彳§' from the current detecting device 27 when the rotary drum 1 is operated to a predetermined rotational speed (for example, 2 rpm). The amount of laundry in the rotating drum 1 is rotated. The commercial power source 31 is connected to the inverter 26 via a DC power conversion device including a diode bridge circuit 32, a choke coil 33, and a smoothing capacitor 34. However, this is only one example, and the configuration of the brushless DC motor 5, the configuration of the inverter 26, and the like are not limited thereto.

Further, the display device 22 further has a soft holding display portion 22i that displays a soft hold after the drying operation. 10 Next, a tank cleaning procedure for washing foreign matter adhering to the inner and outer surfaces of the rotary drum 1 and the inner wall surface of the water tank 3 in the washing machine constructed as described above will be described with reference to the flowchart of Fig. 6. In Fig. 6, first, when the groove cleaning mode is set by the second mode setting switch 21i in the setting device 21 (stroke S601), the control device 15 is passed through the water supply passage 15 from the water supply valve 14. The water is supplied to the set water level (for example, 150 mm) in the water tank 3 to a level equal to or higher than the highest water level in the normal washing operation. After the water is supplied to the set water level, the user presses the start/suspend switch 21e to suspend, and the user opens the cover 7 and directly puts the detergent into the rotary drum 1 (stroke S602). The water supply to the set water level is 20 in order to maximize the soaking effect of the washing liquid. Then, the user closes the cover 7 and presses the start/pause switch 21e again, and then proceeds to the next line (stroke S603). Since the detergent is a chloride-based bleach, if it is directly put into a resin detergent box or a stainless steel rotary drum, the resin may be deteriorated 15 1261638 or the stainless steel may be damaged. Therefore, it is preferable to carry out the work as described above. Next, in order to dissolve the detergent to prepare a cleaning liquid, the control device 20 rotates the rotary drum 1 at, for example, 35 r/min for 5 minutes (stroke S603), and in order to soak the cleaning liquid on the inner surface of the rotary drum, The rotation of the rotary drum 15 is stopped, for example, for 4 minutes (stroke S604··rotation stop stroke). Then, the rotary drum 1 is rotated (forward rotation) in a clockwise direction (stroke S605) in a clockwise direction (for example, 20 seconds) at a first set rotation speed (for example, 35 r/min), and then, the same The first set rotational speed is rotated counterclockwise (reverse rotation) within the same set time (stroke S606). These strokes S605 and S606 10 correspond to the first washing stroke. In the first washing stroke, the rotating drum 1 is alternately rotated forward and reverse, whereby not only the inner and outer surfaces of the drum 1 but also the uneven portions on the inner and outer surfaces thereof can be washed by the water flow in the left-right direction. Next, the control device 20 determines whether or not the set time A has elapsed (for example, 2 minutes) (stroke S607), and when it has not passed (No), the strokes 15 S605 and S606 are repeatedly executed. Thereby, turbulent flow is generated at the time of switching between the forward rotation and the reverse rotation of the rotary drum 1, so that the washing effect of the rotary drum 1 is improved. When the result of the determination in the stroke S607 is that the set time A has elapsed (Yes), for example, 2 minutes, that is, when the forward rotation and the reverse rotation of the rotary drum 1 are repeated three times, respectively, the first washing stroke is ended, and the second washing stroke is entered. Washing stroke. In the second washing course, first, the control device 20 generates a second set rotation speed which is higher than the first set rotation speed and which can generate a rotation speed of the circulating water flow between the outer surface of the rotary drum 1 and the inner wall surface of the water tank 3. 140r/min) Rotate the rotary drum 1 in a clockwise knitting direction (forward rotation) as viewed from the front in the set time (for example, 30 seconds) (stroke S608), and then turn the same at the same second setting by 16 1261638. Rotate counterclockwise (reverse) during the set time (stroke S6〇9). In the second washing stroke, the friction and the force generated during the rotation of the rotary drum cause a water circulator to be generated between the outer surface of the rotary drum 1 and the inner wall surface of the water tank 3, and The groove portion 3 of the water tank 3 causes the circulating water to abort the turbulent flow and the eddy current, and the rotary drum 1 alternately rotates forward and reverse, thereby not only the inner wall surface of the melon water tank 3 but also the uneven portion of the inner wall surface. It can be washed with water in the left and right direction. Next, the control device 20 determines whether or not the set time 6 has elapsed (for example, 2 minutes) (stroke S610), and if it has not exceeded (N〇), the strokes %〇8 1〇 and S609 are repeatedly performed. Thereby, turbulent flow is generated at the time of switching between the forward rotation and the reverse rotation of the rotary drum, and the washing effect of the water tank 3 is improved. If the judgment result in the stroke %1〇 is that the set time B (Yes) has elapsed, for example, 2 minutes, that is, the forward rotation and the reverse rotation of the rotary drum machine are performed twice, respectively, the stroke S6n is entered, and it is judged whether it is longer than the longer one. Set time C (for example, 1 hour). 15 However, if the set time C (No) has not been exceeded, the process returns to the stroke S604, and the first washing stroke and the strokes S608, S609, and S61 of the strokes s6〇5, S606, and S607 are repeatedly executed. The second washing stroke. For example, t— ί, in a long set time C, the combination of the first washing line 2 ^, the + second washing stroke and the rotation stopping stroke is repeatedly performed, whereby the detergent residue attached to the 2 〇 can be washed. Or mildew. In this way, when the set time C has elapsed (the determination in the step S611 is Yes), the draining stroke (stroke S612) is entered, and the control device 2〇 passes through the drain passage and the drain valve 13 to contain the slave rotating drum 2 The inner and outer surfaces and the washing liquid of the foreign matter peeled off from the inner wall surface of the water tank 3 are discharged. Next, the 17 1261638 rotating drum 1 is rotated at a rotation speed (for example, 9 〇〇r/min) at the time of dehydration for, for example, 3 minutes (stroke S613: rotation stroke of the rotary drum), and then, similarly to the stroke (10), the control device 20 is supplied from the water supply valve. 14 is supplied through the water supply passage 15 to the water tank 3 to a set water level (for example, 150 mm) equal to or above the highest water level in the normal washing operation (stroke S614: water supply stroke). Then, similarly to the second washing stroke, the rotating drum is rotated clockwise (forward rotation) in a clockwise direction (for example, 3 sec.) at a second set rotation speed (for example, 14 kg/mm). S615: The rotation stroke of the rotary drum is 'continued' by 10 counterclockwise rotation (reverse rotation) at the same second set rotation speed for the same set time (stroke S616: rotation stroke of the rotary drum). The scrubbing by the combination of the drain stroke, the feed water stroke, and the rotary drum rotation stroke is performed only for a set number of times (for example, four times), and when the set number of times ends (the judgment in the stroke S617 is Yes), the drain 2 is performed ( In the stroke S618), the tank cleaning procedure for washing the foreign matter adhering to the inner and outer surfaces of the rotating drum and the inner wall surface of the water tank 3 is completed. In this way, since the tank cleaning program can be implemented only by the user using the second mode setting switch 21i of the wheeling device 21 to set the tank cleaning mode, the heat must be manually set to feed water, wash, and drain. And washing, the washing stroke of the rotary drum 1 and the water tank 3 can be performed. 20
