200530455 IX. Description of the invention: [Technical field of the invention] [Technical Field] The present invention relates to a drum-type washer-dryer, and the drum-type washer-dryer is equipped with a rotation in a sink. Congzheng Rotating drum tilted down towards the back side. BACKGROUND ART FIG. 7 shows a structure of a drum-type washing machine related to the conventional technology. In the washing machine body 67, a rotating drum 61 is placed in a water tank 63 such that its rotation axis direction is in the X-plane direction. Open the door 64 on the front side of the washing machine body 67, and wash the strip from the door 64 and form it in the water 15 tank 63. The strip comes out π68 and is thrown into the rotating drum ㈣, and is driven by the drum The motor 65 rotates the rotary drum 61, whereby the laundry stored in the rotary drum _ is hung on the ridge protrusion provided on the sloping wall of the rotary drum 61, and is lifted by the heart, and the lifted strips are removed from the appropriate It can be dropped at a high level, so that m strips can be beaten (refer to Patent Document υ).

At, by adding the drying function 1 to the drum-type washing machine towel having the above-mentioned structure, a drum-type washer-dryer is provided which has dehydrated laundry or wet clothes in addition to plum washing. That is, if the air is discharged from the water tank 63, the air containing the moisture in the rotary drum 61 is discharged from the tooth holes 62 formed on the eve of the number of people. Therefore, the air is sent to the water tank by being heated by the heating device after being wetted by the dehumidifier. The inner working hole follows the% path, which can make the washing articles stored in the rotating drum 20 20 200530455 or the clothes dry. However, since the rotating drum of a drum type washing machine or a washer-type washer is arranged in the horizontal direction, the laundry must be put in and taken out from the front side. Not suitable for narrow living environment. In order to solve the problem of the drum-type washer-dryer, the rotary shaft center can be inclined and the opening side of the rotary drum can be faced up, so that the laundry can be easily put in and taken out, and can also be arranged in a narrow space. Inside drum-type washer-dryer (see Patent Document 2). [Patent Document 1] Japanese Patent Gazette _ Heisei No. 10 Pages 2 to 6 and Figure 1) [Patent Document 2] Japanese Patent Gazette No. __05 (Pages 3 to 5 and Figure 2) [Examination of the matter] The disclosure of the invention 15 Problems to be solved by the invention == If the rotating drum is tilted relative to the horizontal direction, the laundry stored in the rotating drum will be concentrated in a lower position in the rotating drum, that is, Concentrate on the bottom side of the rotating drum formed into a bottomed cylindrical shape. Furthermore, when the rotating drum is rotated, it is hung on the protrusions on the inner peripheral surface of the rotating drum and raised in the circumferential direction. When the lifted strip is dropped from the top, it will fall to the bottom surface side of the rotating roller. Therefore, the rotation of the rotating drum will cause the washing object to function on the bottom side. Therefore, in a tumbler-type washer-dryer having a structure in which a rotating drum is disposed obliquely, there is a problem that the washing and drying functions cannot be uniformly spread over all the laundry. 200530455 In particular, in the drying step, warm air must be blown to the laundry uniformly to promote drying. However, since there is no water in the rotating drum during the drying step, the washing product cannot move with the flow of water, and as The laundry that has been dried also becomes less susceptible to the agitating effect of the five drop projections provided on the inner peripheral surface of the rotating drum. Therefore, the laundry is accumulated on the bottom surface side of the rotating drum and is prone to occur. Uneven drying or wrinkling problems. An object of the present invention is to provide a drum-type washer-dryer 10 capable of sufficiently agitating the laundry in the drying step even in a structure in which the rotary drum is disposed obliquely. Means to solve the problem In order to achieve the above-mentioned object, a drum-type washer-dryer related to the present invention is a rotary drum that is formed in a sink and has a bottomed cylindrical shape and is driven by a drum driving motor into a suspicious rotation drive. The rotation axis of the rotating drum is 15 = the opening end side is inclined downward toward the bottom side, X, the aforementioned drum-type washer-dryer I, the water supply and drainage of the aforementioned sink, and the aforementioned drum driving motor > turn to perform strip washing, rinsing and The function of each step of dehydration, and has the function of discharging, dehumidifying and heating the air in the rotating drum, and then blowing it to the air circulation in the drum and the rotation of the drum driving motor K ~ drying step, In addition, in the aforementioned drying step, at least _control step ', the standard drying control step is respectively for the majority of the rotation of the rotating drum :: the predetermined rotation time and predetermined rotation stop & Make a description of the rotation of the drum drive motor to perform at least 3 types of 200530455 at the time of the predetermined setting. The control mode can be repeatedly set within the predetermined time. formula. = The above structure 'Since at least three kinds of rotation control modes that can be accommodated in the rotating roller are set in the same way: the strip washing objects have different movements, so different actions are repeatedly performed within a certain period of time. If you set a majority of the rotating diameter core type, the washing operation can be performed in the rotating drum before, after, right, left, and right, or the silk is spread out, or the warm air can be blown to the washing secret. The above material can promote 10 15 dryness and dry efficiently to prevent uneven drying or in the above structure, in addition to the standard drying control step described above, this initial drying control step is to control the foregoing 2 Drive the spin of the ride so that it is scheduled at the beginning of the drying step. In addition, most of the rotation control modes are repeatedly executed within a short period of time, so that the drying control can be set according to the state of large water content. In addition to the quasi-drying_control step, the final drying step is set. The final drying control step is to control the aforementioned roller driving horse to turn at the final stage of the drying step. Most of the control modes are set at the predetermined setting. , And control the addition of air circulation, ㊉ / &# & order the drying of the laundry corresponding to the dried state and stop heating the supply air, and only use the supply air to continue drying, which can end the drying step At this time, the silk material is in a state of decreasing temperature. In addition to the standard drying control steps, the initial drying control step is also set, and this initial drying control step 20 200530455 controls the rotation phase of the aforementioned drum drive motor, which is reversed in% during the mosquito time in the aforementioned drying step. At the beginning, the final drying control step: the rotation of most of the rotating control molds is executed to repeatedly perform the rotation control in the drum driving motor in the drying step, and ^ 'is heated at a predetermined set time, thereby It can teach from the working state with a large water content and control the air circulation in accordance with the state of the laundry. The state of drying has been performed. As described in the initial drying control step 10 15, the final drying control is switched according to the heart / quasi-drying step and the most, so it can be predicted in each stage of drying; = the elapsed time to control and dry Control steps. The predetermined time setting of the month condition is different. Because of the initial drying control step and the final drying control step, the lack of the control step /, the detection of the dryness of the material to be taken and the washing, and the control can be controlled more effectively. Set each drying control step according to the drying state of H. In addition, according to the amount of laundry stored in the rotating drum, the rotation speed of each of the rotation control modes, the predetermined rotation time between each rotation direction, the pre-rotation stop time, and the predetermined time for repeated execution are set. This' can set the rotation control mode corresponding to the load of the drum drive motor. 20 [Embodiment] The best form of implementing the invention. The first figure shows the structure of the main part of the drum-type washer-dryer 1 related to the embodiment. The sink 3 is supported in the washing machine body 2 by a suspension structure (not shown). 'In the water tank 3, a bottomed cylindrical spin 200530455 rotating drum 5 is arranged. The aforementioned open ends of the sink 3 and the rotating drum 5 are located on the front side of the washing machine body 2 and the front side is located on the back side 5 10 15 'of the washing machine body 2 and the rotating drum 5 is supported so that its rotation axis R faces from the front side The back side is inclined downward at an angle Θ with respect to the horizontal direction H, and X, and the rotary drum 5 can be driven by the drum drive 4 mounted on the bottom surface of the water tank 3 to rotate. The water tank 3 is joined at the open end of the bottom of the water tank body formed in a bottomed cylindrical shape to form a money cover 3b for putting laundry into the rotating drum 5 and taking out laundry from the washing machine, and is formed in the washing machine. The slanted surface 2a on the front side of the machine body 2 is provided with a carcass body 8 which can be opened and closed opposite to the aforementioned laundry person ii. By opening the door body 8, the washing secret can be put into or removed from the rotary drum 5 ', and by forming a part or all of the door body 8 with a transparent body, the inside of the rotary drum 5 can be seen from the outside. In addition, a retractable bladder 13 formed of a soft elastic body is arranged around the product exporter u. When the door 8 is closed, one of the retractable bladder 13 will abut against its inner surface to prevent it from rotating with the drum. The water scattered by the rotation of 5 moves from the sink 3 to the outside. Although the main body 3a of the water tank 3 and the cover body are separated in this embodiment, they can also be formed as a body. For example, when the body is formed of a plastic material such as the cover body 3b, the body can be formed into a body. Moreover, it can be integrally formed even using a metal material. 20 Since the rotary drum 5 is arranged obliquely as described above, and the door body 8 facing the opening part σ is provided on the washing machine body 2, the door body 8 faces the drum type as shown in the external view of FIG. 2 The direction of the face of the person facing the washer-dryer. Therefore, when the door 8 is opened and the laundry is put into or removed from the rotating drum 5, the degree of bending can be reduced, and it can be easily put in and out of 200530455. Washing. In this way, there is no need to secure extra space on the front of the drum-type washer 丨 and a drum-type washer can also be installed in a narrow space such as a washroom of a conventional vertical washing machine 丨 so it can be configured to be suitable Tumble washer-dryer 1 in a narrow residential environment. 5 1〇 15 2〇 刖 回 滁 滁 物 出

The dehumidification tube 16 and the air supply tube are formed on the bottom surface of the water measure 3 in the same way as in Fig. 4. As shown, the heating tube 19 is installed on the bottom surface outside the water tank 3. If the blower fan 15 provided in the heating tube 19 is rotationally driven, the working gas containing moisture in the rotary tube 从 5 will be perforated from most of the holes formed on the peripheral surface. 12 enters the water tank 3, and the air in the water tank 3 is exhausted from the exhaust gas σ2ι to the dehumidification pipe 16. Dehumidification 16㈣ is equipped with a dehumidification device including heat exchange! 51, the heat exchanger 51 is cooled by the water injected from the water injection nozzle by opening the water injection valve 53, and is discharged from the exhaust pipe 21 to the _pipe_ The air will be cooled in the heat exchanger, and the water vapor contained in the fill line will be dehumidified. The water after cooling and heat exchange and the water produced by the condensation will flow into the water tank 3 as shown by the dotted arrows and drain from the drain. The water tank 10 is discharged to the outside. Since the aforementioned dehumidification pipe 16 and the air supply pipe 18 are connected by a connection: on the front side, as shown by the hollow arrow, the dehumidified air passes through the connection officer 32 through the dust removal _17 and borrows.

FIG. 4 illustrates the structure of the heating tube 19 in the state of heating f_equipped heating_, in a state where the lower tube 23 composed of the lower tube 23 and the upper tube 拆除 and the upper tube 接合 are removed after the upper and lower joints are removed. The ^ sent by the aforementioned supply air ㈣ can be heated by the heating ㈣ and becomes warm air of a predetermined temperature, and reaches from the 22 people to the water tank 3. The bottom surface of the rotating drum $ is provided with a plurality of ventilating ridges formed on the circumference. Therefore, warm air from the blowing air D22 blows 12 200530455 5 10 15 20 to the water tank 3 and is blown to the rotating rotating drum 5 The warm air sent from the bottom side will form an air circulation, that is: the laundry contacts and removes its moisture to promote the dry welding of the laundry, and the air containing wet milk will be discharged from the exhaust port 21 again Until the dehumidification tube is repeatedly carried out as the dehumidification and adding the wrong dry. ',,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,, The bottom side of the rotating drum 5 = when the drum 5 rotates, there is a possibility that the washings are more concentrated on the bottom side ^ In order to solve this problem, in the roller 1 related to this embodiment, the roller 1 provided on the rotating drum 5 is used. The inner peripheral surface: from 9 =: and by the rotation control of the rotating drum 5, the structure can be prevented from picking up a specific position inside the drum 5. However, in the dry 'T, do not concentrate on the rotation without water, and the laundry The amount of water contained in it is also reduced, so by stirring the protrusions Health; ^ The drying process is different and the dynamic or rinsing effect of the silk is affected by the rotation speed of the rotating drum 5. Therefore, in the drying step, the washing process must be stopped to prevent the laundry from shifting and can be effective. The drying control performed by the drying staff can be prevented according to Fig. 5 to explain the drying control of the first embodiment of this embodiment. The following reference numerals S1, S2 ... are the steps showing the control sequence, and the numerals in the text shown in Fig. 5 It is the same as "Usuzu", and the washing object enclosed in the rotating drum 5 and dried is shown to be made according to the rotation speed or direction of the rotating drum 5. Therefore, if the rotation of the rotating drum 5 is controlled, Moved to most washing

13 200530455 Action Aihua is stored in a tilted configuration and shows that it is suitable for drying. It can be used as the plum washing in 5 and can be implemented more. And it is more fixed than 5 5 15 2 0 because it is stored in the rotation. The washing in the wave cylinder 5 changes the amount of the laundry to be washed, so it needs to be adjusted. Here, the drum is controlled for 6 ^ and the motor 4 is controlled for a predetermined time, so as to repeatedly perform 3 different washing operations corresponding to each washing operation. In addition, the timing of the laundry is determined as follows :::::: Pre-return of the material. In the figure 5, the amount of laundry is measured to detect the amount of laundry in the storage room 5 (turn / center). u For reading, you can use the method of detecting the washing amount from the doubled state of the drum drive motor 4 to detect the amount of washing, etc., and set to execute the first to third rotation control modes two. In each of the first to third rotation control modes, the rotation speed of the rotary drum 5 is set, the daytime interval between the forward rotation and the suspicious rotation of the rotation roller according to the predetermined rotation speed, the time to stop the rotation in order to switch the rotation direction, and the basis The reverse rotation time of the rotating drum 5 at the set rotation speed. First execute the first rotation control mode, and set the rotation of the drum drive motor 4 so that the rotation speed of the rotation drum 5 becomes the first rotation speed (53), and the rotation drive is performed in the forward direction only during the first rotation time (54) And stop the rotary drive only during the first rotation stop time (55), and only reverse the rotary drive during the first rotation stop time (S6), and then 'stop the rotary drive only during the first rotation stop time (π) . The above-mentioned rotation control mode of the $ 1 rotation is to set the first rotation speed to 80 ~ 120 r / min when the straightness of the rotating shoulder 5 is 500 mm to 50 mm, and to make the rotating drum 5 200530455 forward. 1 rotation time (for example, 2 seconds), it will stop the first rotation stop. Time (for example, 1 second). With this action, in the first! At the rotation speed, the rotation. The impact of a sudden change of direction is applied to the laundry attached to the inner peripheral surface of the rotary drum 5. Therefore, the laundry will be scattered, and as a result, the laundry · 5 will be obtained with the rotary drum 5. The movement of the position of the axis direction. The above-mentioned first rotation control mode is repeatedly executed (for example) within the execution time (for example, 3 minutes) of the i-th rotation control mode set in Step 2. Next, the second rotation control mode is executed, and the rotation of the drum driving motor 々 is set so that the rotation speed of the rotation drum 5 becomes the second rotation speed_10 (S9), and the rotation is performed in the forward direction only during the second rotation time. Drive (S10), and stop the rotation drive (S11) only during the second rotation stop time, and drive the reverse rotation (512) only during the second rotation time, and then stop the rotation only during the second rotation stop time Driver (513). The above-mentioned second rotation control mode is to set the second rotation speed to 20 to 25 r / min when the diameter of the rotating drum 5 is 15 500 ± 50, and to make the rotation / rotation of the drum 5 forward for the second rotation time. (For example, 60 seconds) and stop the bean for the second rotation stop time (for example, 2 seconds). With this action, the rotary drum 5 «can be driven to rotate in the forward and reverse directions at a slow rotation speed, thereby not lifting the strip washing object in the rotation direction, and the knee washing object can be rotated. The drum 5 rolls down and moves forward, backward, left, right, left, and right. Therefore, the silk can be warmed evenly by the warm air blown from below the bottom surface of k. The above-mentioned second rotation control mode will be repeatedly executed (si4) within the execution time (for example, 5 minutes) of the second rotation control mode set in step magic. Next, the third rotation control mode is executed, and the rotation of the drum driving motor * 15 200530455, (515) (516) (S17) 5 (S18), (S19) 〇 makes the rotation speed of the bismuth rotation drum 5 to the third rotation And rotates in the forward direction only during the third rotation time and stops the rotational drive only in the third rotation stop time and drives the reverse rotation only in the third rotation time. Then, only in the third rotation stop time Stop the rotation and move the third rotation control mode. When the diameter of the rotating drum 5 is 50 mm, the third rotation speed is set to% ~ 45r / min, and the rotating drum 5 is rotated forward for the third rotation time (for example, 60. Seconds), and stop the third rotation h stop time (for example, 2 seconds), and make the rotating drum $ reverse the third rotation 10 time W such as 60 seconds), and stop the third rotation stop time ( (E.g. 2 seconds). With this action, the laundry can be lifted in the direction of rotation by the rotation of the rotary drum 5, and the laundry can fall from its own weight position that exceeds the centrifugal force or the fractal dimension, and the laundry The upper and lower positions are swapped and exposed to warm air to give people dryness. The above-mentioned third rotation control 15 mode is repeatedly executed within the execution time (for example, 5 minutes) of the third rotation control mode set in step S2 (S20). Each of the rotation control modes of C $ 2 and C3 is repeatedly executed within the set time set in the drying step (S2i). In addition, the execution order of each of the first, second, and third control modes is not limited to the order shown in FIG. 20, and the execution order may be changed. In addition, it is advisable to set at least three rotation control modes, and it is more effective to set three or more. As described above, in the first rotation control mode, the drying step is performed after the laundry is affixed to the inner peripheral surface of the rotating drum 5 so as to facilitate the exchange of the axial direction. In the second rotation control mode, , To make the laundry tumble in the rotating 200530455 drum 5 to stir forward, backward, left and right, and in the third rotation control mode, the warm air is blown evenly to the plum to promote drying. The above-mentioned rotation / rotation control of rotation 5 can be performed as shown in Fig. 6; in the drying step, only the above-mentioned rotation control program is executed, or it can be performed as shown in Fig. 6 and 5 and 6 (c) ® 6 (d). The above-mentioned rotation control is used as the standard dry control step (A) ', and the initial drying control step (B) and the final drying control step (C) are appropriately set before and after the standard drying control step (A). In the drying progress state, the drying step is divided into a plurality, and the rotation speed, the rotation time in the forward direction, the rotation stop time, and the reverse direction are set to 10 in the order shown in Figure 5 in each stage. Rotate control mode for rotation time and repeated execution time. The drying progress state can be determined based on the elapsed time of the drying step or the detection of the dry state. The detection of the dry state may be a method using a dry sensor, and the dry state may also be detected from the detection output of the cooling water temperature sensor 57 and the supply air temperature detector 15 and the detection sensor 56. In addition, the cooling water temperature sensor As shown in FIG. 3, the detector 57 is used to detect the temperature of the water flowing into the drain tank 10 after cooling the heat exchanger 51, and the supply air temperature detection sensor 56 is shown in FIG. 4. , For detecting the temperature of the air blown to the heating pipe 19. 2 The control shown in Fig. 6 (b) shows a control example of the initial drying control step (B) set before the standard drying control step (A). This initial drying control step (B) will be described with reference to FIG. 5. In the initial drying control step, the first initial rotation speed is set to 20 to 25 r / min (S3), and the rotary drum is driven to rotate forward in the first rotation time (for example, 30 seconds) 5 17 200530455 (S4) , And stop spinning only within the first initial rotation stop time (for example, 2 seconds) and drive the rotation toward the reverse rotation by 5 (S6) within the first initial rotation time of 苐 1, and then only during the first initial rotation stop time Stop the rotation (S7), and repeatedly execute the control (S8) within the execution time (for example, knife, ri) of the initial rotation control mode, thereby, because the rotating drum 5 has a slow rotation speed throughout the day, therefore, There is no effect of lifting washing in the direction of rotation, and it is possible to stir the laundry to the left and right under the rotating drum 5. Therefore, the green laundry can be evenly changed by the warm air blowing from below the bottom surface. warm. 10 15 20

Following the implementation of the first initial rotation control mode described above, the second initial rotation speed is set to 8 (M2 () r / min (S9)), and it is driven to rotate forward in the second initial rotation time (for example, 2 seconds). Rotating roller $ ⑹, and only at

2Stop rotation (SU) within the initial suspected stop time (such as ice), and drive in the reverse rotation direction (Si2) only during the second initial rotation time, and stop the rotation only during the second: ) And iteratively executes the control within the second initial rotation :: traversing time (for example, 1 minute) 14) 'In the second initial rotation speed, the impact of a sharp change in the rotation direction is applied purely in rotation _ _ Washing, therefore, washing = Do not become scattered, as a result, you can get the action of swapping the position of the axis direction of washing secret and rotation. As described above, since the washing record is wet, u is not easy to cause the evil of the enemy pattern. Therefore, the initial drying control step is a step based on the second-rank style, which is based on the Qianlingji spoon and changing the position. 18 200530455 After the above-mentioned initial drying control step (B) is repeatedly performed until the preset time is reached or the drying state is detected, the above-mentioned # 准 草 a drying control step (A) is performed. Further, as shown in Fig. 6 (c), it may be set to execute the final drying control step (C) after the standard drying control step 5 (A). The final drying control step (C) is performed in a state where the heating by the blower air of the heater 20 has been stopped, and only the shield ring of the blower air of the blower fan 15 is used to dry the laundry in the dried state to perform Air-cooling step to reduce the temperature of the laundry. That is, since excessive drying is unreasonable for clothes and the like, 10 will also waste power consumption. Therefore, when the degree of dryness is detected and a predetermined degree of dryness is detected, the heating by the heater 20 is stopped and transferred. To the air cooling step using only the supply air. This final drying control step (c) can be set in the same manner as the control program shown in Fig. 5 and the rotation control and time control of the standard drying control step ⑷. 15 & As described above, in the final drying control step, the laundry is not easy to wrinkle, and the laundry is exchanged in the axial direction of the rotary drum 5. Therefore, in the first rotation control mode, After the objects are affixed to the inner peripheral surface of the rotating drum 5, they are scattered to promote the exchange position in the axial center direction, and in the second rotation control mode, the strip washing object is rolled inside the rotating drum 5, Do n’t mix the strips from side to side, and in the first domain transfer control mode, make the cold wind evenly blow to the washing, and the air intake is cold. Second, as shown in FIG. 6 (d), if the initial drying control step (B), the standard drying control step (A), and the final drying control step (c) are performed by using 6 of the above-mentioned rotation control modes, You can get a more effective dry state of 200530455. In this embodiment, in addition to the above-mentioned rotation control of the rotating drum 5, a structure is provided in the rotating drum 5 to facilitate the movement of laundry. As shown in FIG. 1, the reverse filter 30 for preventing the laundry from flying from most of the air vents 39 formed on the bottom surface 5 of the rotary drum 5 to the water tank 3 is formed as a spherical surface that draws a gentle arc. The laundry stirred by the rotation of the rotary drum 5 easily hits the reverse filter 30 and slides toward the front side. The reverse filter 30 is densely formed with many small holes so that the warm air sent from the air vent 39 can easily enter the rotary drum 5, and the surface facing the inside of the rotary drum 5 is smooth and easy to slide. The reverse filter 30 can be formed into a smooth surface that is easy to slide according to the choice of the metal or resin as the material for forming the reverse filter 30. However, for a smoother surface, a material with a low coefficient of friction such as fluorinated resin or polyacetal can be formed on the surface, or A coating is applied to the surface of these materials. Further, as shown in Fig. 1, corner embedding materials 15 to 31 are distributed in the corners, so that the corner portion from the inner peripheral surface to the inner bottom surface of the rotary drum 5 becomes a curved surface or an inclined surface. Since the inner peripheral surface of the corner-embedding material 31 is formed as an arc surface or an inclined surface, and at the same time as a smooth surface with good sliding properties, it is easy for the laundry to fall from above by the stirring performed by the rotation of the rotary drum 5 The laundry 20 is moved to the front side, and the laundry 20 sliding on the reverse filter 30 is easily moved to the front side. As described above, the corner embedding material 31 may not be distributed in the corner portion, and the corner portion from the inner peripheral surface to the bottom surface of the rotary drum 5 may be formed in a circular or “C” shape. A ring-shaped balancer 34 is arranged on the side and the bottom surface side to suppress the vibration caused by the rotation. Therefore, a corner 200530455 embedding material 31 which can be easily formed by resin molding should be provided.
