A method of combining foreign matter 15 such as black mold spots caused by the metal soap produced or the ume plum I produced by the microorganisms acting on the metal soap (for example, refer to Patent Document 1). In this conventional example 1, since the rotating shaft of the washing tank is provided in the vertical direction, water is supplied to the washing tank to a predetermined water level, a dose is poured, and the stirring blade is rotated for a predetermined time to make Washing solution. After washing, use the immersion stroke of the washing tank to rotate intermittently, so that the washing liquid is spread on the outer wall of the first tank or the inner wall of the outer tank, and perform the dipping process within a predetermined time, so that the washing liquid is fully aligned. The foreign body acts to shut off the foreign body. However: Rotate the stirring blade again, and send the washing material from the pump chamber to the line filter through the 'I' ring water line, and the foreign material contained in the cleaning liquid line filter. To 20 200521285 Recently, there are also rotating drum-type washing machines for washing, washing, and dewatering in a rotating drum with a rotation center axis in a horizontal direction or an inclined direction (for example, refer to Reference 2: Conventional Example 2). 5 10 15 [Patent Document 1] Japanese Patent Publication _ r ^% Japanese Patent Publication No. 2002-248295 [Patent Literature 2] Japanese Patent Publication. Yin Kekai No. 10-201991 C Presentation Content] | Invention of the Invention Revealing the problem to be solved by the invention is as in the above-mentioned conventional example 1. In a washing machine where the vertical axis v rises and the central axis is suspected, the water level is used to make the washing liquid, and the inner and outer walls of the washing tank and the outside The inner wall of the tank is almost fully immersed in the button cleaning solution. Therefore, the foreign matter on the outer wall and the inner wall of the outer tank can be sufficiently washed by the rotation of the washer and the mixing wing. Renru Example 2 'above is that in a drum type washing machine with a rotation center axis in the horizontal or inclined direction, water can only be supplied to the inner and outer surfaces of the rotary drum and the inner wall surface of the water tank containing the rotary drum—partly, There is no proposed method for cleaning foreign matter adhering thereto, and even if the method # 1 of the conventional example 1 is applied, the cleaning effect is sufficiently obtained. In view of the above-mentioned conventional problems, an object of the present invention is to provide a washing machine that can sufficiently obtain the washing effect of foreign matter adhered to the inner and outer surfaces of a rotating drum having a rotation center sleeve in a horizontal direction or an inclined direction and an inner wall surface of a water tank. . In order to achieve the above object, a washing machine related to the present invention includes: a rotating drum 'made to accommodate washing secrets 4 in a horizontal square oblique direction 20 200521285 has a center axis of rotation; a water tank, which contains the aforementioned rotating drum, and elastically supports On the washing machine body; the motor can drive the aforementioned rotating drum; the water supply device is used to supply water to the aforementioned water tank; the input setting device is used to set the action of the washing machine; and the control device is used to perform the input from the aforementioned 5 The control of the washing operation set by the setting device, the control of the water supply device and the motor, and in the absence of load without washing in the rotating drum, the control device controls the water supply device to supply water to the In the water tank and after reaching the set water level, control the aforementioned motor to perform the following combination of strokes multiple times within the set time. These strokes include: the 10th washing cycle, which makes the aforementioned rotating drum rotate at the first set speed; the second washing stroke , The rotating drum is rotated at a second set speed, and the second set speed is higher than the foregoing The first set rotation speed is high and the rotation speed of the circulating water flow can be generated between the outer surface of the rotating drum and the inner wall surface of the water holding tank; and the rotation stop stroke stops the rotating drum. 15 According to this configuration, the inner and outer surfaces of the rotary drum can be cleaned by the first washing stroke in which the rotary drum is rotated at a first set speed (low speed, such as 35 r / min). In addition, the second washing stroke that rotates the rotating drum at a second set speed (high speed, such as // min), causes the friction and centrifugal force generated on the rotating drum to rotate on the outer surface 20 of the rotating drum. A circulating water flow is generated between the inner wall surface of the water tank and the inner wall surface of the water tank can be washed by the generated circulating water flow. In particular, particles of detergent or scales scattered during washing remain in the upper part of the rotating drum and the water tank, and the strip washing water cannot be reached, and the washing can hardly be performed. However, the upper part can be washed by the above-mentioned circulating water flow. In addition, by stopping the stroke of the rotation of the rotating drum, it can be obtained that 200521285 u the shredded fruit in the material container consumes less power. In addition, by 'can reduce the number of times due to W &W; in the & long set time (for example, 10 hours) 5 10 15 = the combination of the second fine money line and the second washing and cutting material, can be washed Residues or mold spots on the lotion. The forward rotation of the Dingtong is irradiated on each set of materials to make the rotary tumble washing: ^ If it is made in 1st, the rotating drum rotates at the first set speed of the first… wrong circle of water to wash the surface of the water tank, but " By switching the forward rotation and reverse rotation of the rotating drum, the uneven portion on the inner wall surface of the water tank can be left and right, and when the forward rotation and reverse rotation are repeated, turbulence is caused at the point t on the switching day, and it can be obtained Washing effect. In the washing machine related to the present invention, the control device should perform the second washing; the motor is controlled to alternate the forward rotation and reverse rotation of the rotating drum at each set time 0. According to the above structure, The second washing stroke that rotates the rotating drum at the second set speed can be used to wash the inner wall surface of the water tank by circulating water flow. However, by switching the forward rotation and reverse rotation of the rotating drum, the left and right water flows can be used. The concave and convex part of the inner wall surface of the water tank is washed, and turbulence can be caused at the time of switching when the forward rotation and reverse rotation are repeated, and the washing effect can be obtained. In the washing machine related to the present invention, it is set The water level should be equal to or higher than the positive level when there is laundry in the rotating drum The highest water level during the washing operation.

At the same time, when the setting operation is started by the rotation setting device 21, the rotation comes from the detection tank 3. The water level in the water level is detected by the data of 5 devices 16 and the like, and the actions of the drain pan 13, the water supply valve 14, the air supply fan 17, and the heater 18 are controlled by the load driving device 23 to perform washing and drying operations. At this time, the control device 20 controls the inverter 26 through the drive circuit 25 · 10 based on the information from the position detection device 24 (24a, 24b, 24c) that detects the rotor position of the motor 5 to control the rotation of the motor 5 . The motor is converted to a brushless DC motor and consists of a stator (not shown) with a three-phase coil and a rotor equipped with a ring-shaped two-pole permanent magnet. The stator is composed of the first coil 5a and the second coil of the magic phase coil. The coil 5b and the third coil 5c are formed by being wound around an iron core provided with a slit. The 15 k changer 26 is composed of a switching element composed of a power transistor (for example, an insulated gate-type diode (IGBT)) and a parallel circuit of a reverse conducting diode. The switching element is a series circuit of the second switching element and the second switching element, the third switching element 26c and the fourth switching element 26 (the series circuit of the first, the fifth switching element 26e, and the sixth switching element 26f are connected in series by the old switching element). The circuit is composed of 20%, and the series circuits of the switching elements are connected in parallel. Here, the two ends of the series circuit of the switching elements are input terminals and are connected to the DC power supply, and two series circuits of the switching elements are formed. The connection points of the switching elements are respectively connected to the output terminals. The output terminals are connected to the U, V, and w terminals of the 3-phase coil. According to the on and off combination of the two switching elements that constitute the serial circuit of the switching element 12 200521285 The difference is that the u # sub, the V terminal and the W terminal are set to three states of positive voltage, zero voltage and release. The switching device is turned on and off by the control device 20 according to 50% of the three positions formed by the Hall IC. Controlled by information from the detection devices 24a, 24b, and 24c. The position detection devices 24a, 24b, and 24c are arranged on the stator at 120-degree phase angle intervals and face the permanent magnets of the rotor. Rotate the rotor 1 During the week, the three position detection devices 24a, 24b, and 24c output pulses at intervals of 120 degrees. The control device can detect 10 signals from any of the three position detection devices 24a, 24b, and 24c. When the state can change, the on and off states of the switching elements 26a to 26f are changed according to the signals from the position detection devices 24a, 24b, and 24c, so that the u terminal, v terminal, and W terminal become positive voltage, zero voltage, and release 3 In this state, the first coil 5a, the second coil 5b, and the third coil 5c of the stator are energized, and a magnetic field is generated to rotate the rotor at 15. The switching elements 26a, 26c, and 26e are respectively subjected to pulse width modulation (PWM). Control, for example, to control the high and low energization ratios at a repetitive frequency of 10 kHz, thereby controlling the rotation speed of the rotor, and the control device 20 detects the period when the signal state of any of the three position detection devices 24a, 24b, 24c changes, And the rotation speed of the rotor is different from the 20 忒 period, and the switching elements 26a, 26c, and 26e are PWM-controlled to reach the set speed. The current detection device 27 includes a resistor 28 connected to one of the input terminals of the inverter 26 and该 电 The electricity It consists of a 28-phase current detection circuit, and detects the input current value of the inverter 26, and supplies its output voltage to 13 200521285 to the control I set to 20. When the motor 5 is a brushless DC motor, due to the torque and wheel current It is approximately proportional. Therefore, the current of the inverter 26 can be detected by the current detection circuit 29 connected to the resistor 28 to detect the torque of the motor 5. 5 The laundry amount detection device 30 is used to detect the inside of the rotating drum 1. The amount of the laundry is detected based on a signal from the current detection device 27 when the rotary drum 1 is operated to a predetermined rotation speed (for example, 200 rpm). The commercial power source 31 is connected to the inverter 26 through a DC power source conversion device constituted by a diode bridge circuit 32, a choke coil 33, and a smoothing capacitor 34. However, this is only one example, and the structure of the brushless DC motor 5 and the structure of the inverter 26 are not limited thereto. As shown in FIG. 5, the input setting device 21 includes a washing time setting switch 21a for setting the washing time, a washing time setting for the number of washing times, a setting switch 15b, and a dehydration time setting for setting the dehydration time. Switch 21 c, daytime setting switch 21 d, start / pause switch 21e, power input switch 21f, power cut-off switch 2ig, etc. The input setting device 21 is provided with a first mode setting switch 21h and a second mode setting switch 21i. 20 The 14th mode setting switch 21h is a switch for setting the operable mode, and each time it is started, the settings can be switched in the following sequence to perform a series of washing, scrubbing, dehydrating, and drying processes, etc. , Scrubbing and dehydration modes, and only the drying mode. The second mode setting switch 21ι can be switched in the following order every time it is activated. 14 200521285 Change the setting of automatic mode, fast wash mode, self-set mode, blanket mode, and tank cleaning mode.

C Therefore, if it is directly injected, the resin may be deteriorated. As a detergent, a gaseous bleaching agent is used. The resin is washed or dispersed in a steel rotating drum. 15 200521285 Or the stainless steel is damaged. Therefore, it is preferable to perform the work as described above. In order to make the detergent > disintegrate into a washing liquid, the control device 20 rotates the rotary drum 1 at 35 r / min for 5 minutes (stroke% 03), and immerses the washing liquid in The inner surface of the drum is rotated, and the rotation of the rotary drum 15 is stopped for, for example, 4 minutes (stroke S604: rotation stop stroke). Then, rotate the rotary drum 1 at a first set speed (for example, 35 r / min) in a set time (for example, 20 seconds) in a clockwise direction (forward rotation) when viewed from the front (Xingsui S605). The first set speed of rotation is rotated counterclockwise (reverse) within the same set time (stroke S606). These itineraries 5605 and% 060 are equivalent to brother 1's washing trip. In this first washing stroke, by rotating the rotary drum 1 alternately forward and reverse, not only the inner and outer surfaces of the rotary drum i, but also the uneven portions on the inner and outer surfaces of the drum i can be washed with water flowing in the left-right direction. Next, the control device 20 determines whether the set time eight (for example, 2 minutes) has elapsed (stroke S607) ′ When it has not exceeded (No), it repeatedly executes the strokes 15% 05 and% 06. As a result, a turbulent flow occurs at the time of switching between the normal rotation and the reverse rotation of the rotary drum 1, so that the cleaning effect of the rotary drum 1 is maintained. When the judgment result in the stroke S607 is that the set time A has passed (for example, 2 minutes), that is, when the forward rotation and the reverse rotation of the rotary drum 1 are repeated 3 times, the i-th washing cycle is ended, and the 2nd washing cycle. 20 In the second washing stroke, first, the control device 20 is set at a second set speed that is higher than the first set speed and can generate a circulating water flow between the outer surface of the rotating drum 1 and the inner wall surface of the water tank 3 (for example, 14〇r / min) Within a set time (for example, 30 seconds), make the rotating drum 丨 turn forward in a clockwise direction when viewed from the front (forward rotation) (stroke S608), and then turn to 200521285 speed with the same second setting Rotate counterclockwise in the same set time (line 9). In the fourth and second washing line, the friction and separation due to the rotation of the rotary drummer. Force causes a fire to circulate between the outer surface of the rotating drum 1 and the inner wall surface of the water tank 3. The groove part 300 of the water tank 3 causes the circulating water stream 5 to turbulently and vortex, and causes the rotating drum to work. The forward rotation and the reverse rotation are alternately performed, whereby not only the inner wall surface of the water tank 3 but also the uneven portions of the inner wall surface can be washed with water flowing in the left-right direction. Next, the control device 20 determines whether the set time B (for example, 2 minutes) has elapsed (stroke S610), and if it does not exceed (N0), it repeats the stroke s_ spear S609 to thereby forward and reverse the suspect rotation of the drum 丨Turbulent flow occurs at the time of switching the rotation, and the washing effect of the water tank 3 is improved. If the judgment result in the stroke% 10 is that the set time B (Yes) has elapsed, for example, 2 minutes, that is, the forward rotation and the reverse rotation of the rotating drum i are performed twice respectively, then the stroke is entered, and it is judged whether it exceeds a longer time. Set time c (for example, οh). 15 However, if the set time C (No) has not been exceeded, return to the rotation stop stroke in stroke S604, and repeat the first washing stroke of strokes S605, S606, and S607 and the first washing stroke of strokes S608, S609, and S610. 2 Washing trip. In this way, in a long set time C, the combination of the first and second washing strokes, the second washing stroke, and the rotation stop stroke is repeatedly performed multiple times, thereby washing the residues of the lotion or mildew on the lotion 20, etc. . In this way, when the set time c has elapsed (Yes in stroke 5611), it enters the drainage stroke (stroke S612), and the control device 20 will pass through the drainage passage 12 and the drainage valve 13 to The cleaning liquid of the foreign matter peeled off from the inner and outer surfaces and the inner wall surface of the water tank 3 is discharged. Next, the 17 200521285 rotating drum 1 is rotated at a rotation speed (for example, 900 r // min) for 3 minutes (stroke S613: rotating stroke of the rotating drum), and then, the same as the stroke% 02, the control device 20 removes the water from the water supply valve. 14 Water is supplied into the water tank 3 through the water supply channel 15 to a set water level equal to or higher than the highest water level during normal washing operation (for example, 150mn0 (stroke S614 ·· water supply stroke). Next, and The second washing stroke is the same. At the second set speed (for example, / min), the rotating drum is rotated (forward rotation) in a clockwise direction in a set time (for example, 30 seconds) (Stroke S615: Rotation stroke), and then rotate (counterclockwise) counterclockwise at the same second set speed at the same second setting speed (stroke% 16: rotation stroke of the rotating drum). From the above drainage line%, water supply stroke, The scrubbing performed by the combination of the rotation stroke of the rotating drum is performed only for a set number of times (for example, 4 times), and when the set number of times is over (the judgment in the stroke S617 is Yes), the drainage stroke is performed (line feS618) 'The end of the tank cleaning program for cleaning foreign matters adhering to the inner and outer surfaces of the rotating drum worker 15 and the inner wall surface of the water tank 3. In this way, since the tank cleaning program is only set by the user using the input = The second mode setting switch 21i of the device 21 can automatically apply the washing mode of the tank, so there is no need to manually set the water supply, washing, drainage and washing, and the cleaning stroke of the rotating drum 1 and the water tank 3 can be performed. In addition, in the present embodiment, although the shape of the groove portion 300 of the water tank 3 is formed such that the side wall surface 300a is at a right angle or an acute angle with the bottom lion, it is explained, but the present invention is not limited to this, as long as it is a rotating drum i Rotating the sun guard at the second rotation speed can generate the shape of turbulent flow and hole flow in the circulating water flow generated between the outer surface of the rotating drum ⑽ and the inner wall surface of the water tank $. 18 200521285 And '本 贯 施 形 g' Although the case of using a brushless DC motor as the motor 5 has been exemplified and explained, the present invention is not limited to this, and the present invention is also used even if a brush DC motor or an induction motor is used and the driving device and method thereof are changed, In addition, the same effect as that of the present invention can be obtained. In addition, the other structures described in this embodiment and each stroke (including the set water level, set speed, and set time) in the tank cleaning program are merely examples, and their modifications Examples and modifications are also included in the present invention based on the technical ideas in the scope of the patent application. The washing machine related to the present invention has the advantage of sufficiently obtaining the cleaning effect and collection of foreign objects. Detergent residue and mildew on the inner and outer surfaces of the rotating drum with the center axis of rotation in the direction and the inner surface of the water tank are useful for rotating drum-type washing machines.
