Description

Clothing treatment device (4) Field of invention

The present invention relates to a laundry treating apparatus having a door for closing and opening an opening for feeding in and out of clothes.

Background of the invention

A laundry treating machine, a dryer, or a washing and drying machine, which processes a laundry (washing treatment, dehydration treatment, cleaning treatment, or drying treatment), generally has a casing and a treatment tank housed in the casing (laundry) Slot, dewatering tank or drying tank). The treatment tank performs a predetermined treatment of washing, washing, dehydrating or drying by performing a rotary motion. The casing is formed with an opening that is used to feed the laundry in the conventional processing tank and to take out the laundry from the processing tank.

A washing machine disclosed in Japanese Laid-Open Patent Publication No. 2000-279679 and Japanese Laid-Open Patent Publication No. 2009-95529 has a door body that is attached to the casing and that is openable at a closed position for closing the opening and opening Freely rotate between the open positions of the department. The door in the open position allows the laundry to be placed in the laundry tank and the laundry to be removed from the laundry tank. The door in the closed position isolates the user from the rotating laundry tank and prevents the laundry from scattering outside the basket.

The opening 215 communicates with a washing and drying trough (described later) housed inside the casing 200. The user puts in or takes out clothes (clothing or the like) inside and outside the casing 200 through the opening portion 215. In the present embodiment, the laundry dryer tank is exemplified as a treatment tank. If the laundry treating apparatus does not have a washing machine capable of drying, the washing tank for washing, washing, and/or dehydrating can also be used as a processing tank. When the laundry treating apparatus is a clothes dryer that does not have a washing machine, the drying tank for stirring the clothes to promote drying can also be used as a processing tank.

The washer-dryer 100 has a hinge structure 400 that allows the door body 300 to be rotatably coupled to the housing 200. With the hinge structure 400, the door body 300 can be rotated between a closed position for closing the opening 215 and an open position for opening the opening 215. The door body 300 that is rotated to the closed position is received in a concave field surrounded by the concave surface 214. Furthermore, the door body 300 shown in Figs. 1 and 2 is in an open position.

Figure 3 is a schematic cross-sectional view of the washer-dryer 100 having the door 300 in the closed position. The overall configuration of the washer-dryer 100 will be further described using Figs. 1 to 3. Further, the structure other than the structure inside the casing 200 shown in Fig. 3 can also be applied to the laundry treating apparatus.

As shown in FIG. 3, a laundry dryer tank 110 is disposed inside the casing 200. The laundry drying trough 110 includes a bottomed cylindrical water tank 111 which is supported by a rocking body inside the casing 200, and a bottomed cylindrical rotating body which is rotatably supported in the water tank 111. Roller 112. The inside of the casing 200 is further provided with a motor 113 for rotating the rotary drum 112. The motor 113 is mounted outside the bottom of the water tank 111. The opening of the water tank 111 is formed by a cylindrical portion 114 of a substantially cylindrical shape that protrudes toward the door body 300 in the closed position. The sealing member 115 having a substantially cylindrical shape is fitted to the barrel portion 114.

As shown in FIGS. 1 and 2, the door body 300 includes a transparent window portion 310 having a bottom portion and a substantially trapezoidal conical shape, and a support frame 320 having a substantially circular plate shape supporting the window portion 310. As shown in FIG. 3, when the door body 300 is disposed at the closed position, the window portion 310 is inserted into the opening portion 215 formed in the casing 200, and is crimped to the sealing member 115 attached to the water tank 111. Further, a watertight seal structure is formed between the water tank 111 and the window portion 310. During the closed position of the door 300, the user can visually view the laundry in the laundry dryer tank 110 through the transparent window portion 310. Further, when the door body 300 is in the closed position, the surface of the door body 300 facing the opening portion 215 and/or the concave surface 214 is referred to as an inner surface 313.

As shown in Fig. 3, the water tank 111 forms a discharge port 116 for discharging the washing liquid, and an inflow port 117 into which the washing liquid flows. The washing liquid used for washing is recycled between the discharge port 116 and the inflow port 117.

The inside of the casing 200 further houses: a water supply system 120 for supplying water into the water tank 111; a drainage system 130 for draining or circulating the washing liquid in the water tank 111; and a warm air for drying the laundry into the washing machine Drying system 140 of tank 110. Further, if the laundry treating apparatus is a washing machine that does not have a drying function, the drying system 140 is not required. Further, if the laundry treating apparatus is a dryer that does not have a washing machine, the water supply system 120 or the drainage system 130 may not be used.

The drying system 140 includes a circulation line 142 having one end connected to the exhaust port 141 of the water tank 111, and a vent for feeding the drying air from the bottom of the water tank 111; and being disposed in the circulation line 142 A blower 143 that internally and allows air to flow within the circulation line 142. The drying system 140 may also include a filter for collecting cotton dust and dusting, a dehumidifying portion for dehumidifying the introduced air after dedusting, and a heating portion for heating the dust-removed air and manufacturing the dried high-temperature air, as needed. .

As shown in FIGS. 1 and 2, the washer-dryer 100 has an operation panel 500 disposed on the upper wall 213. The operation panel 500 is a mode in which the user can select the operation stroke of the washer-dryer 100 or various functions. As shown in FIG. 3, the operation panel 500 includes a control circuit unit 510. The control circuit unit 510 displays the information input by the user on the display unit of the operation panel 500. Further, when the operation of the washer-dryer 100 is started through the operation panel 500, for example, a liquid level sensor for detecting the liquid level in the water tank 111, and a turbidity sensor for detecting the turbidity of the washing liquid. The light sensor 131 used, or the electrode sensor 132 used as the conductive sensor for detecting the conductivity of the washing liquid receives the detection signal, and according to the detection signals, performs the electromagnetic system included in the water supply system 120. Control of the machine of the drain valve 133 contained in the valve or drainage system 130. The motor 113, the water supply system 120, the drainage system 130, and the drying system 140 are automatically controlled by the control circuit unit 510 according to a mode setting or control program, and perform a washing step, a washing step, a dehydrating step, and a drying step.

As schematically shown in FIGS. 1 and 2, the washer-dryer 100 has a locking mechanism 600 that locks the door body 300 in the closed position. The control circuit unit 510 is used as a control element for controlling a lock control unit (described later), and the lock control unit cooperates with the lock mechanism 600 to lock the door body in the closed position.

As shown in FIG. 3, the water supply system 120 includes a water supply line 121 connected to the water tank 111, and a lotion accommodating portion 122 for storing a lotion. As shown in FIG. 1, the top wall 250 of the casing 200 is provided with a lid 251 for closing the lotion accommodating portion 122.

The water supply system 120 shown in Fig. 3 can be supplied to the water tank 111 in a timely manner via the water supply line 121 by the switching operation of the electromagnetic valve (refer to the solid arrow in Fig. 3). Further, the washer-dryer 100 can supply the lotion in the lotion accommodating portion 122 disposed partially across the water supply line 121 into the water tank 111 in a timely manner by the water supply of the water supply system 120.

The drainage system 130 includes: a first line 134 having one end connected to the discharge port 116 of the water tank 111; a drain control unit 135 connected to the other end of the first line 134 and receiving the washing liquid from the water tank 111; The drain control unit 135 has a second conduit 137 extending between the circulation pump 136 and the water tank 111. The circulation pump 136 is fixed to the bottom plate 138 disposed in the casing 200. One end of the second line 137 is connected to the discharge port of the circulation pump 136, and the other end of the second line 137 is connected to the inlet 117 of the water tank 111. The water tank 111, the first line 134, the drain control unit 135, and the second line 137 form a circulation path of the washing liquid. The circulation pump 136 flows and circulates in the washing liquid circulation path from the discharge port 116 toward the inflow port 117.

The drain control unit 135 includes, in addition to the circulation pump 136, a photo sensor 131 used as a turbidity sensor for detecting the turbidity of the washing liquid, and as a conductive sensing for detecting the conductivity of the washing liquid. The electrode sensor 132 used by the device, the drain line 139 for discharging the washing liquid to the outside, the drain valve 133 disposed in the middle of the drain line 139 and opening and closing the drain line 139, and the collection by the first The filter portion 191 of the lint (grit yarn, etc.) contained in the washing liquid flowing into the line 134.

The drain valve 133 can be opened as needed at the end of the washing step or at the end of the washing step. As a result, the washing water that has flowed into the drainage control unit 135 from the first line 134 is subjected to the removal process of the lint by the filter unit 191, and then discharged to the outside.

By closing the drain valve 133, the circulation pump 136 is actuated, and the washing liquid stored in the water tank 111 flows into the drain control unit 135 through the first line 134. Then, the washing liquid is removed by the filter unit 191 disposed in the drain control unit 135. After passing through the filter unit 191, the washing liquid flows into the circulation pump 136 through the suction line 192 connected to the suction port of the circulation pump 136, and returns to the water tank 111 through the second line 137 connected to the discharge port of the circulation pump 136. Inside. During the execution of the washing step or the washing step, the circulation of the washing liquid can be repeated as needed, and as a result, the washing step or the washing step can be performed efficiently.

The number of revolutions of the circulation pump 136 is variable. When the number of rotations of the circulation pump 136 is set high (for example, 3500 rpm), the washing liquid flowing into the inlet 117 of the water tank 111 moves along the trajectory toward the inside of the rotary drum 112 (refer to arrow Fi in Fig. 3). On the other hand, when the number of rotations of the circulation pump 136 is set low (for example, 1000 rpm), the washing liquid flowing into the inlet 117 of the water tank 111 is formed in the space formed between the rotary drum 112 and the water tank 111 (refer to FIG. 3). Medium arrow Fo).

The circulation pump 136 performs low-speed rotation at the start of at least one of, for example, the washing step and the washing step. Thereby, the high-concentration softening agent after the completion of the washing or the softening agent after the completion of the washing becomes difficult to be sprayed on the laundry in the rotary drum 112.

The washing liquid that has flowed into the space between the rotating drum 112 and the water tank 111 is discharged to the drain system 130 by the discharge port 116, and is returned to the inflow port 117 of the water tank 111 again (the inner tank circulating step). By repeating the circulation step in the water tank, the lotion is completely dissolved and the concentration of the softener is uniform. As a result, problems such as the spots of the laundry which dissolves the residual lotion or the high-concentration softener become difficult to occur.

The circulation step in the water tank is preferably set to, for example, about 10 seconds after the water supply step of the washing step and/or the washing step. Alternatively, it is preferable that, for example, when the detection liquid level is about 40 mm from the lower end of the water tank 111, the inner tank circulation step is started. Thereby, it is difficult to cause the circulation pump 136 to operate in a state where the washing liquid is not sufficiently filled in the circulation pump 136. Therefore, the abnormal noise of the bubble sound of the circulation pump 136, the abnormal temperature of the circulation pump 136 due to the insufficient amount of the washing liquid, and the operation of the circulation pump 136 at the abnormal temperature hardly occur.

The washer-dryer 100 may further have a pump for supplying bath water to the water tank 111. In this case, the bath water is supplied to the water tank by the pump for supplying the bath water, and the inside of the water tank is circulated. Thereby, the pump for supplying the bath water and the circulation pump 136 do not operate at the same time, and noise that is uncomfortable to the user can be prevented.

The user can operate the operation panel 500 to set a scheduled operation for the washer-dryer 100. When the washing and drying machine 100 performs the scheduled operation, the circulation step in the water tank is preferably performed for a period of twice the length of the normal time. As a result, the lotion which is solidified during the reservation standby (during the start of the reservation setting until the actual washing and drying machine 100 starts to operate) can be sufficiently dissolved. Therefore, during the scheduled operation, sufficient detergency can be obtained and it is difficult to cause a problem of residual lotion.

The washer-dryer 100 is provided with a temperature sensor as needed. The length of the circulation step in the water tank may also be changed in response to the temperature of the wash water measured using the temperature sensor. For example, when the temperature sensor detects the temperature of the washing water of 5 ° C, it is possible to perform, for example, a step in the water tank which is a multiple of the temperature at which the temperature of the washing water of 20 ° C is detected. Thereby, the lotion can be sufficiently dissolved even at a low water temperature.

As shown in FIGS. 1 and 2, the washer-dryer 100 has a handle portion 700 that is attached to the support frame 320 of the door body 300 by abutting the lock mechanism 600. The user can grip the handle portion 700 protruding from the support frame 320 to rotate the door body 300 between the closed position and the open position.

(structure of the door body)

Fig. 4 is a schematic cross-sectional view of the door body 300. Fig. 5 is a schematic exploded perspective view of the door body 300. The door body 300 will be described using Figs. 1, 4, and 5.

The door body 300 has the window portion 310 and the support frame 320 as described above. The glass window portion 310 is formed in a substantially trapezoidal conical shape. When the door body 300 is rotated toward the closed position, the head wall 311 is formed to be smaller than the circular space surrounded by the slightly circular edge portion 312 of the support frame 320 before being inserted into the opening portion 215 (refer to FIG. 1). small. The slightly annular inclined wall 314 extending from the slightly rounded front head wall 311 toward the edge portion 312 is abutted against the sealing member 115 (see Fig. 4).

The support frame 320 includes a slightly annular mounting ring 321 , a substantially circular outer cover disk 322 that covers the mounting ring 321 from the outside, and a slightly annular edge ring 323 that is fitted to the outer periphery of the outer cover disk 322 . The surface of the outer cover disk 322 has a curved face that is substantially identical to the curved main wall 212. The surface of the cover disk 322 is curved along the main wall 212 so that the user can easily clean the cover disk 322. The mounting ring 321 is provided with a handle portion 700, a locking mechanism 600, and a hinge structure 400 in addition to the window portion 310. The hub structure 400 and the locking mechanism 600 are arranged substantially neatly on a horizontal line along the diameter of the door body 300. As shown in FIG. 1, the hinge structure 400 and the locking mechanism 600 are respectively disposed at slightly opposite ends of the diameter of the door body 300. The handle portion 700 is adjacent to the locking mechanism 600 and disposed above the locking mechanism 600.

As shown in FIGS. 4 and 5, the support frame 320 further has a slightly annular pressure ring 324. The pressure ring 324 cooperates with the mounting ring 321 to clamp the edge portion 312 of the window portion 310. The mounting ring 321 and the pressure ring 324 are used as support portions for supporting the handle portion 700, the locking mechanism 600, and the hinge structure 400.

As shown in Fig. 5, the pressure ring 324 has a slightly L-shaped cross section. When the door body 300 is in the closed position, the flat surface 325 of the pressure ring 324 facing the inner side of the casing 200 and the front surface 311 of the window portion 310 form the inner surface 313 of the door body 300. An inclined surface 326 extending from the flat surface 325 of the pressure ring 324 to the mounting ring 321 forms a portion of the circumference of the door body 300.

As shown in FIG. 4, the concave surface 214 of the casing 200 includes: a connecting surface 216 opposite the flat surface 325 of the pressure ring 324 when the door body 300 is in the closed position; and when the door body 300 is in the closed position, The inclined surface 326 of the pressure ring 324 opposes the opposing surface 217. As shown in FIGS. 1 and 4, the opposing surface 217 faces the outer periphery of the door body 300. As shown in FIG. 5, the hinge structure 400 has the first connecting member 410 and the second connecting member 420. As shown in FIG. 1, the first connecting member 410 is connected to the connecting surface 216. The second connecting member 420 is connected to a surface 327 on which the ring 321 is attached opposite to the pressure ring 324 (see FIG. 5).

(construction of the hub mechanism)

Fig. 6 is a perspective view of the door body 300 from the side of the inner surface 313. Furthermore, the door body 300 shown in FIG. 6 removes the pressure ring 324 and the handle portion 700. 7 and 8 are perspective views of the mounting ring 321 to which the hinge structure 400, the locking mechanism 600, and the handle portion 700 are attached. The mounting rings 321 of Figures 7 and 8 are depicted by mutually different angles. The configuration of the hub structure 400 will be described with reference to Figs. 5 to 8.

The pivot structure 400 includes a pair of arm pieces 430 protruding from the first connecting member 410 that is attached to the connecting surface 216 and formed of a crescent-shaped zinc alloy to the second connecting member 420; and a pair of arm pieces 430 A support shaft portion 440 supported at both ends; and a torsion coil spring 450 that winds the support shaft portion 440 between the pair of arm pieces 430. The torsion coil spring 450 is exemplified as a potential energy member that penetrates the support shaft portion 440 and transmits the potential energy of the door body 300 toward the open position through the first connection member 410 and the second connection member 420.

In the following description, the opening angle of the door body 300 at the closed position is described as "0 degree". If the opening angle of the door body 300 is 30 degrees or more, the torsion coil spring 450 gives the potential energy of the door body 300 toward the open position. If the opening angle of the door body 300 is in the range of 0 to 30 degrees, the door body 300 moves toward the closed position. When the opening angle of the door body 300 is 30 degrees or less, when the user's hand leaves the door body 300, the door body 300 gradually rotates toward the closed position, and then stops near the closed position. Therefore, when the user's hand does not intend to leave the door body 300, the door body 300 may become difficult to rotate to the open position.

The pair of arm pieces 430 support the fulcrum portion 440 at a position away from the first connecting member 410 attached to the joint surface 216. The second connecting member 420 made of a galvanized steel sheet molded by bending and torsion processing has high rigidity. The second connecting member 420 includes a connecting piece 422, and the connecting piece 422 is formed with an opening portion 421 that is fitted to an end portion of the support shaft portion 440. The support shaft portion 440 made of stainless steel is rotatably fitted to the opening portion 421 of the connecting piece 422. Further, since the support shaft portion 440 is rotatably supported by the second connection member 420 connected to the door body 300, the door body 300 is rotatably attached to the casing 200 via the hinge structure 400. Furthermore, the arm piece 430 is preferably made of metal. If the arm piece 430 is formed using a metal having high rigidity, the hinge structure 400 can also be miniaturized. The small hub construction 400 can properly hold the door 300. In the present embodiment, the arm piece 430 is formed by casting using a zinc alloy. The arm piece can also be formed by using other metals. Further, since the second connecting member 420 is formed by bending a metal steel sheet, the second connecting member 420 can cooperate with the arm piece 430 to appropriately hold the door body 300 having the glass window portion 310 and having a heavy weight.

The pressure ring 324 is formed with a substantially rectangular cutout portion 328 through which the arm piece 430 is inserted. Further, the second connecting member 420 disposed inside the door body 300 is appropriately coupled to the first connecting member 410 disposed outside the door body 300.

(Structure of the handle part)

As shown in FIGS. 5 and 6, the outer edge region of the surface 327 of the mounting ring 321 of the pressure ring 324 includes a slightly flat restricting surface 329 and a concave side surface 331, and the slightly flat restricting surface 329 is recessed. The concave area of the handle portion 700 can be accommodated. When the door body 300 is in the closed position, the regulating surface 329 faces the connecting surface 216 of the casing 200 (see FIG. 1).

Figure 9 is a schematic cross-sectional view of the washer-dryer 100 around the handle portion 700. Furthermore, the door body 300 shown in Fig. 9 is in the closed position. The handle portion 700 will be described using Figs. 1 and 5 to 9.

The handle portion 700 includes a first piece 710 disposed between the mounting body 321 including the mounting ring 321, the cover disk 322 and the edge ring 323, and the connecting surface 216 forming the concave surface 214; and the second piece 720 It is curved away from the direction of the opposing face 217 where the concave surface 214 is formed. The first piece 710 is located between the restriction surface 329 and the casing 200 when the door body 300 is in the closed position. The second piece 720 includes an exposed piece 721 which is present on the outer surface of the casing 200 when the door body 300 is in the closed position, and a connecting piece 722 which connects the exposed piece 721 and the first piece 710. As shown in FIG. 6, the periphery of the pressure ring 324 is formed with a notch portion 332. The notch portion 332 is recessed toward the center of the door body 300. The connecting piece 722 along the periphery of the door body 300 protrudes outward of the casing 200 through the notch portion 332. When the door body 300 is in the closed position, a gap of about 20 mm is provided between the exposed piece 721 and the casing 200. The user's finger is easily inserted into the gap. Further, the exposed piece 721 is extended by about 20 mm from the vicinity of the outer periphery of the door body 300. The user can rotate the handle portion 700 and the insertion piece 190 (described later) with a small force. Also, the exposed sheet 721 can be easily viewed from the front and is easy to handle. In addition, the first piece 710 is located on the inner surface side of the door body 300, and does not hide the door body 300 and the edge ring 323, so that high designability around the door body 300 can be maintained.

As shown in FIG. 5, the pair of support shaft portions 711 protrude from the both side edges of the first sheet 710. The fulcrum portion 711 is rotatably supported by the concave side surface 331. Moreover, the first piece 710 is rotatably supported by the mounting ring 321. Furthermore, the first piece 710 disposed between the mounting ring 321 and the pressure ring 324 can also be supported by the pressure ring 324.

As shown in Fig. 9, the surface 333 of the mounting ring 321 opposite to the first piece 710 in the vicinity of the outer periphery of the mounting ring 321 and the peripheral surface 334 of the outer peripheral edge of the mounting ring 321 opposed to the first piece 710 are substantially On the same side, the above-mentioned restriction surface 329 is formed.

The user can hold or hold the exposed piece 721 of the second piece 720 to rotate the door body 300 from the closed position to the open position. At this time, the first piece 710 that is rotatably supported by the mounting ring 321 is rotated to approach the restriction surface 329. Then, the first piece 710 abuts against the restriction surface 329 and restricts the rotation of the first piece 710. Further, the support shaft portion 711 is attached with, for example, a torsion coil spring, and the potential energy of the handle portion 700 in the direction away from the restriction surface 329 of the first piece 710 may be imparted.

(locking mechanism)

10 and 11 are enlarged perspective views of the door body 300 around the locking mechanism 600. In Figures 10 and 11, the door 300 is depicted by mutually different angles. The locking mechanism 600 will be described using FIGS. 5, 7, 8, 10, and 11.

The locking mechanism 600 has a locking arm 610. The locking arm 610 forms an insertion piece 190 together with the detecting arm 810 disposed on the locking arm 610. A detecting arm 810 integrally formed with the locking arm 610 is used to detect the position of the door body 300. The washer-dryer 100 can use the detection arm 810 to detect that the door body 300 is in the open position or the door body 300 is in the closed position.

As shown in Fig. 5, the pressure ring 324 is formed with an opening portion 335 having a substantially rectangular shape. As shown in FIGS. 10 and 11 , the lock arm 610 and the detection arm 810 are protruded from the support frame 320 via the opening 335 formed in the pressure ring 324 .

As shown in FIG. 5, the locking mechanism 600 has a rotating shaft 620 that rotatably supports the insertion piece 190, and a torsion coil spring 630 that is wound around the rotating shaft 620. The mounting ring 321 has a pair of ribs 336 that protrude toward the pressure ring 324. A pair of ribs 336 are respectively formed with notch portions 337. Both ends of the rotating shaft 620 are inserted into the notch portion 337, and the rotating shaft 620 is rotatably coupled to the mounting ring 321. The insertion piece 190 is rotatably coupled to the rotating shaft 620 via a torsion coil spring 630. As shown in FIGS. 10 and 11, the insertion piece 190 is rotated about the rotation axis 620 between the engagement position and the release position. When the insertion piece 190 is rotated toward the outer edge of the door body 300, the front end of the insertion piece 190 is locked toward the locking position of the door body 300. When the insertion piece 190 is rotated toward the center of the door body 300, the front end of the insertion piece 190 is directed toward the release position of the door body 300. The torsion coil spring 630 imparts potential energy to the insertion tab 190 toward the engaged position.

Fig. 12 schematically shows the positional relationship between the handle portion 700 and the insertion piece 190. The locking mechanism 600 will be further described using FIGS. 1 , 3 , 5 , 7 , 8 , and 10 to 12 .

The insert piece 190 includes a base plate 611 having a substantially rectangular plate shape. The base end plate 611 is used as a common base end of the lock arm 610 and the detection arm 810, and the lock arm 610 and the detection arm 810 are protruded from the base end plate 611. The rotating shaft 620 penetrates the base end plate 611. The front end portion 612 of the lock arm 610 is formed in a hook shape and protrudes toward the outer peripheral direction of the door body 300. The base end plate 611 has a larger amplitude than the opening portion 335. Therefore, if the locking mechanism 600 is disengaged within the door body 300, the locking mechanism 600 will remain in the door body 300. As a result, regardless of the door body 300 being in the open position, the locking mechanism 600 may become difficult to remain in the locking hole 218.

As shown in Fig. 12, the corner portion of the base end plate 611 (the angle of the center axis C1 of the insertion piece 190 (corresponding to the rotation axis 620) closer to the center of the door body 300) is disposed in the mounting ring. 321 is between the first piece 710 of the handle portion 700. As shown in FIGS. 10 and 11, when the door body 300 is rotated from the closed position to the open position, the handle portion 700 is rotated so that the first piece 710 approaches the restriction surface 329 formed on the mounting ring 321. As a result, in the inner side of the door body 300 closer to the rotary shaft 620, the corner portion of the base end plate 611 is pressed by the first piece 710, and the front end portion 612 of the lock arm 610 is toward the release position (ie, the door) Inside the body 300) moves.

As shown in FIG. 1, the connecting surface 216 of the casing 200 is formed with a locking hole 218 having a substantially rectangular shape and a detecting hole 219. A lock control unit 640 is disposed inside the casing 200 (refer to FIG. 5). The lock control unit 640 is fixed to the inner surface of the casing 200. The locking control unit 640 incorporated in the housing 200 forms a locking hole 218 and a detecting hole 219. Further, the locking hole 218 and the detecting hole 219 may be formed as one opening or may be separated from each other by the wall portion of the housing 200. The lock control unit 640 is controlled by the control circuit unit 510.

Figure 13 is a schematic cross-sectional view of the lock control unit 640. The figures 13(a) to 13(c) continuously show the actions of the lock control unit 640. The right diagrams of Figures 13(a) through 13(c) show the locking arms 610 that are inserted into the locking control unit 640. The left side of Figures 13(a) through 13(c) show the detection arm 810 inserted into the lock control unit 640. The lock control unit 640 will be described using FIGS. 1 , 3 , 10 , 11 , and 13 .

As described above, the lock control unit 640 attached to the inner surface of the casing 200 forms a locking hole 218 in the casing 200. The locking hole 218 is inserted with the front end 612 of the locking arm 610. The lock control unit 640 forms a detection hole 219 on the housing 200. When the door body 300 is in the closed position, the front end of the detecting arm 810 is inserted into the detecting hole 219.

The lock control unit 640 includes a housing 641 that houses a circuit or a component for achieving the operation of the lock control unit 640, and a lock box 642 that is disposed inside the housing 641. The lock box 642 is formed in the housing 641 to receive a common internal space for the front end portion 612 of the lock arm 610 and the front end portion of the detection arm 810.

The position of the lock box 642 shown in Fig. 13(a) is referred to as a permitted position. When the locking box 642 is in the permitted position, the locking arm 610 and the detecting arm 810 can be detached from the locking position 218 and the detecting hole 219 by the door body 300 being rotated from the closed position to the open position. The position of the lock box 642 shown in Fig. 13(c) is referred to as an unlicensed position. When the locking box 642 is in the disapproved position, the front end portion 612 of the locking arm 610 is engaged with the housing 641 of the locking control unit 640 and/or the housing 200 of the washer-dryer 100, so that the user cannot make the door The body 300 is rotated from the closed position to the open position. The position of the lock box 642 shown in Fig. 13(b) is referred to as an intermediate position. When the locking box 642 is in the intermediate position, the inner space of the locking box 642 is partially in communication with the locking hole 218 and the detecting hole 219. When the door body 300 is rotated from the open position to the closed position, the front end portion 612 of the locking arm 610 and the front end portion of the detecting arm 810 can enter the inner space of the locking box 642 through the locking hole 218 and the detecting hole 219. At this time, the lock box 642 can be instantaneously moved to the permission position shown in Fig. 13(a) by coming into contact with the front end portion 612 of the lock arm 610. The gentle curved shape of the front end 612 of the locking arm 610 facilitates the movement of the locking arm 610 into the locking box 642 and the locking box 642 to the permitted position. Then, by the potential energy of the locking arm 610 to the engaged position (refer to FIGS. 10 and 11), the lock box 642 is returned to the intermediate position. When the locking box 642 is in the intermediate position, the front end portion 612 of the locking arm 610 is gently engaged with the housing 641 of the locking control unit 640 and/or the housing 200 of the washer-dryer 100.

The casing 641 houses a drive source (not shown: for example, an electromagnetic switch or a spring) for moving the lock case 642. The control circuit unit 510 controls, for example, an electromagnetic switch to move the lock box 642 in the casing 641 between the intermediate position and the unauthorised position. For example, when the user operates the operation panel 500 (refer to FIG. 1) and wants to rotate the laundry drying tub 110 (for example, for laundry processing, cleaning processing, or drying processing), the control circuit portion 510 causes the locking box 642 to move toward the locking box 642. Location movement is not permitted. When the laundry processing, the cleaning process, or the drying process is completed, and the rotation of the laundry dryer tank 110 is stopped, the control circuit portion 510 moves the lock box 642 to the intermediate position.

When the lock box 642 is moved from the intermediate position to the unapproved position, the front end portion 612 of the lock arm 610 is pushed to the inner surface of the lock box 642. As a result, the locking arm 610 is rotated about the rotating shaft 620. At this time, the detecting arm 810 integrally formed with the locking arm 610 via the base end plate 611 is rotated together with the locking arm 610 about the rotating shaft 620 penetrating the insertion piece 190. When the locking box 642 reaches the disapproved position, the hook-shaped protruding portion of the front end portion 612 of the locking arm 610 will completely engage with the housing 641 of the locking control unit 640 and/or the basket of the washing and drying machine 100. Body 200. At this time, even if the user holds the second piece 720 of the handle portion 700, and the handle portion 700 is to be rotated to bring the first piece 710 close to the restriction surface 329, the lock control unit 640 can keep the lock box 642 from being permitted. position. Therefore, the user cannot rotate the door body 300 to the open position. Moreover, the locking aperture 218 cooperates with the locking arm 610 to lock the door 300 in the closed position.

Under the control of the control circuit unit 510, after the lock box 642 is moved to the intermediate position, the user wants to hold the second piece 720 of the handle portion 700 and rotate the handle portion 700 to bring the first piece 710 closer to the restriction surface 329. The front end 612 of the locking arm 610 will face the release position. At this time, the front end portion 612 of the locking arm 610 abuts against the inner surface of the locking box 642, and the locking box 642 moves to the permitted position. Then, when the door body 300 is rotated to the open position, the locking arm 610 and the detecting arm 810 are separated from the locking hole 218 and the detecting hole 219, respectively. Moreover, the locking arm 610 of the locking mechanism 600 is interlocked with the rotation of the first piece 710 of the restriction surface 329 to release the locking of the door body 300 in the closed position.

(detection department)

Fig. 14 is a schematic block diagram of a detecting portion for detecting the position of the door body 300. The detecting unit will be described with reference to Figs. 1, 3, 13 and 14.

The detecting unit 800 has a first detecting element 820 for detecting the presence or absence of the detecting arm 810 in the lock box 642 (that is, the detecting hole 219). The first detecting element 820 can also be any component that is mounted on the light-transmitting sensor of the locking box 642, the push-button type switching element, or the detecting arm 810 in the locking box 642. When the light-transmitting type sensor is used as the first detecting element 820, the optical path of the photo sensor is shielded by the detecting arm 810 inserted into the locking control unit 640, thereby being inserted into the detecting arm 810 in the locking box 642. Can be tested. When the push button type switching element is used as the first detecting element 820, the detecting arm 810 inserted into the locking control unit 640 pushes the switching element, whereby the detecting arm 810 inserted into the locking box 642 can detect.

The detecting unit 800 has a second detecting element 830 for detecting the presence or absence of the locking arm 610 in the locking box 642 (ie, the locking hole 218). The second detecting component 830 can also be a light-transmitting sensor mounted on the locking box 642, a push-button type switching element, or any component for detecting the presence or absence of the locking arm 610 in the locking box 642. When the light-transmitting type sensor is used as the second detecting element 830, the optical path of the photo sensor is shielded by the locking arm 610 inserted into the locking control unit 640, thereby being inserted into the locking arm in the locking box 642. 610 is tested. When the push button type switching element is used as the second detecting element 830, the lock arm 610 inserted into the lock control unit 640 pushes the switch element, and the lock arm 610 inserted into the lock case 642 detects.

The control circuit unit 510 as shown in FIG. 3 can also be used as a part of the detecting unit 800. The control circuit unit 510 includes a determination unit 511 and a control unit 512. The determination unit 511 inputs detection signals from the first detection element 820 and the second detection element 830. Moreover, the operation information input to the operation panel 500 can also be output to the determination unit 511. The determination unit 511 determines the state of the door body 300 based on the detection signals from the first detection element 820 and the second detection element 830, and outputs the determination result to the control unit 512.

The detecting unit 800 may be provided with a warning portion 840 for notifying the user of an abnormality (for example, damage of the locking mechanism 600) in the door body 300. The warning portion 840 can also use, for example, a buzzer that notifies the abnormality of the door body 300 by sound or an abnormal lamp that notifies the door body 300 by light. When the determination unit 511 determines that there is an abnormality in the door body 300, the control unit 512 outputs a signal including the information on the abnormality of the door body 300 to the warning unit 840. Then, the warning unit 840 notifies the user of the abnormality of the door body 300. The determination unit 511 further outputs a determination result regarding the position (closed position or open position) of the door body 300 to the control unit 512. When the door body 300 is in the closed position, the control unit 512 outputs an actuation signal to the motor 113 that rotates the washing and drying tub 110 as the user inputs the operation panel 500 (refer to FIG. 1), and rotates the motor 113. . On the other hand, when the door body 300 is in the open position, the control unit 512 does not output an actuation signal to the motor 113 that rotates the washing and drying tub 110 regardless of the user's operation panel 500 (see FIG. 1). Moreover, the rotation of the laundry dryer trough 110 during the open position of the door body 300 can be prevented. In addition, when the door body 300 is in the open position, when the operation panel 500 performs an operation for rotating the laundry drying tub 110, a signal indicating that the door body 300 is in the open position may be output to the warning portion. 840. As a result, the warning unit 840 outputs a sound or light that notifies the user that the door body 300 is in the open position.

Fig. 15 is a flow chart schematically showing the operation of the detecting unit 800. The operation of the detecting unit 800 will be described with reference to Figs. 13 to 15 .

The user inputs operation information for causing the washer-dryer 100 to perform a desired operation through the operation panel 500 (S100). The determination unit 511 determines the position of the door body 300 based on the detection signal from the first detecting element 820 (S110). When the detection signal from the first detecting element 820 includes the information of the detecting arm 810 in the lock box 642, the determining unit 511 determines that the door body 300 is in the closed position. When the detection signal from the first detecting element 820 includes information indicating that the detecting arm 810 does not exist in the lock box 642, the determining unit 511 determines that the door body 300 is in the open position.

When it is determined that the door body 300 is in the closed position, the determination unit 511 determines whether or not the operation information input to the operation panel 500 includes information requesting the rotation of the laundry dryer tank 110 (S120). When the determination unit 511 determines that the operation information input to the operation panel 500 includes the information requesting the rotation of the laundry dryer tank 110, the control unit 512 activates the motor 113 based on the determination result, and rotates the laundry dryer tank 110 according to the operation information. (S130). When the determination unit 511 determines that the operation information input to the operation panel 500 does not include the information requesting the rotation of the laundry dryer tank 110, the control unit 512 causes the washer-dryer 100 to perform the rotation of the laundry dryer tank 110 in accordance with the operation information. Control of actions other than (S140).

When it is determined that the door body 300 is in the open position, the determination unit 511 determines whether or not the detection signal from the second detecting element 830 includes information indicating that the lock arm 610 is in the lock box 642 (S150). When the detection signal from the second detecting element 830 indicates that the locking arm 610 is not present in the locking box 642, the determining unit 511 determines whether the operation information input to the operation panel 500 includes information indicating that the rotation of the washing and drying tub 110 is required (S160). ). When the determination unit 511 determines that the operation information input to the operation panel 500 does not include the information requesting the rotation of the laundry dryer tank 110, the control unit 512 causes the washer-dryer 100 to perform the rotation of the laundry dryer tank 110 in accordance with the operation information. Control of actions other than (S140). When the determination unit 511 determines that the operation information input to the operation panel 500 includes information requesting the rotation of the laundry dryer tank 110, the control unit 512 outputs a signal indicating that the door body 300 is in the open position, to the warning unit 840. Instead of rotating the laundry dryer tank 110. Then, the warning portion 840 notifies the user that the door body 300 is in the open position, and prompts the user to rotate the door body 300 to the closed position (S170). The determination unit 511 determines the position of the door body 300 again (S110).

When the determination unit 511 outputs a detection signal from the second detecting element 830 indicating that the locking arm 610 is present in the lock box 642, the control unit 512 outputs a signal including information indicating that the locking mechanism 600 is damaged to the warning unit. 840. Then, the warning portion 840 notifies the user of the damage of the locking mechanism 600 (S180). This result is a change in the locking mechanism 600.

(connection structure between the door body and the housing)

16 and 17 are schematic enlarged views of a connection portion between the door body 300 and the casing 200. The door body 300 shown in Fig. 16 is in the closed position. The door body 300 shown in Fig. 17 is in an open position. The connection structure between the door body 300 and the casing 200 will be described with reference to Figs. 16 and 17 .

As described above, the door body 300 is connected to the housing 200 via the hinge structure 400. The first connecting member 410 of the hinge structure 400 is made of a zinc alloy and is connected to the joint surface 216 of the casing 200. The second connecting member 420 having high rigidity formed by bending and twisting the galvanized steel sheet is connected to the mounting ring 321. The arm piece 430 protruding from the first connecting member 410 to the second connecting member 420 supports the support shaft portion 440 at a position away from the first connecting member 410 and/or the connecting surface 216. The stainless steel support shaft 440 is held in a position protruding from the concave surface formed by the concave surface 214. The outer edge of the outer cover disk 322 and the edge ring 323 form a curved edge portion 338 which is formed to partially surround the support shaft portion 440.

As the door body 300 is rotated, the outer edge 423 of the second connecting member 420 is also rotated. The outer edge 423 abuts against the receiving edge 433 of the arm piece 430 by restricting the rotation of the door body 300. Further, the outer edge of the arm piece 430 has a curved edge 431 for the front end portion 339 to enter with the rotation of the door body 300. The curved edge 431 is curved toward the center of the door body 300 in the closed position as shown in Fig. 16 (i.e., curved away from the opposing surface 217). When the door body 300 is rotated toward the open position, the front end portion 339 of the curved edge portion 338 enters the recess of the curved edge 431. Further, in the present embodiment, the front end portion 339 of the curved edge portion 338 is made of resin and corresponds to the edge portion of the edge ring 323. Moreover, the outer edge 423 abuts against the receiving edge 433 of the arm piece 430, thereby restricting the rotation of the door body 300 that is rotated by the closed position, thereby limiting the open position to a predetermined position.

As shown in FIG. 16, when the door body 300 is in the closed position, the front end portion 339 of the curved edge portion 338 is located between the opposite side surface 217 of the slanted slope portion 221 and the arm piece 430 in the left and right side edges of the main wall 212. . The distance (the shortest distance) between the front end portion 339 and the opposite surface 217 of the curved edge portion 338 is preferably 5 mm or less. Therefore, the gap width between the arm piece 430 and the opposing surface 217 is narrowed by the front end portion 339 of the curved edge portion 338. Further, the front end portion 339 of the curved edge portion 338 enters the concave region formed by the concave surface 214 and is located closer to the imaginary plane P along the joint surface 216 than the fulcrum portion 440.

As shown in Figs. 16 and 17, the curved edge 431 of the arm piece 430 forms a space R between the opposite side surface 217 for moving the end portion 339 before the curved edge portion 338. When the door body 300 is rotated between the closed position and the open position, the front end portion 339 of the curved edge portion 338 moves within the space R. When the door body 300 is rotated from the closed position to the open position, the front end portion 339 of the curved edge portion 338 moves toward the curved edge 431 along the circular arc trajectory. When the door body 300 reaches the open position, the front end portion 339 of the curved edge portion 338 does not abut the curved edge 431. Thereby, it is difficult to cause the front end portion 339 to be damaged when the resin body front end portion 339 comes into contact with the metallic bending edge 431 when the door body 300 reaches the open position. In the present embodiment, the front end portion 339 of the curved edge portion 338 does not abut the curved edge 431 after the door body 300 is rotated by 90° from the closed position (for example, when rotated by 105° from the closed position), and the second connecting member 420 is not abutted. The outer edge 423 abuts against the receiving edge 433 of the arm piece 430 to restrict the rotation of the door body 300.

Referring again to FIGS. 2 and 5, the connection between the door body 300 and the casing 200 will be further explained.

Fig. 2 shows an oblique line L of the lead straight line V and the inclination angle θ from the lead straight line V. Moreover, the lead line V0 formed in the center of the opening portion 215 of the casing 200 is further shown in FIG. The inclined line L passes through an imaginary line attached to the central axis of the pivot portion 440 of the hinge structure 400 of the housing 200.

As shown in FIG. 5, the support shaft portion 440 includes a first end portion 441 and a second end portion 442 opposite to the first end portion 441. In the oblique line L shown in FIG. 2, the first end portion 441 is located above the second end portion 442. Further, in the oblique line L shown in FIG. 2, the second end portion 442 is disposed closer to the lead straight line V0 than the first end portion 441. Moreover, the door body 300 in the open position can continue to maintain the open position by gravity.

As shown in FIG. 2, the first connecting member 410 of the hinge structure 400 is fixed to the connecting surface 216 by, for example, a screw 411 (or another fixing means for attaching the first connecting member 410 to the connecting surface 216). Therefore, the joint surface 216 is formed with a mounting hole that extends in a direction perpendicular to the joint surface 216. The position of the mounting hole is preferably set to a window portion 310 of the door body 300 that is rotated by 90° from the closed position, and the window portion 310 protruding from the pressure ring 324 is not located at a central axis of the mounting hole (an imaginary line extending in a direction perpendicular to the connecting surface 216) )on. Further, the door body 300 is not properly hindered from being connected to the casing 200.

The laundry treating apparatus according to one aspect of the present invention includes: a casing having an opening for allowing the laundry to enter and exit; and the door body being closed at a position for closing the opening and opening to open the opening Rotating between positions; and a handle portion for rotating the door body between the closed position and the open position, wherein the handle portion includes: a first piece that is rotatably supported by the door body, And a second piece extending from the first piece and exposed to the outside of the casing when the door body is present in the closed position, the door body including a restriction surface, when the door body is present in the closed position The frame body faces and restricts the rotation of the first piece, and the first piece is located between the housing and the restriction surface when the door body is present in the closed position, and when the door body is closed by the foregoing When the position is rotated toward the open position, the first piece is brought into contact with the regulating surface to restrict the rotation of the handle portion.

According to the above configuration, the user can take out the laundry through the opening formed in the casing. The door body of the laundry treating device is rotatable between a closed position at which the opening is closed and an open position at which the opening is opened. The door in the closed position inhibits the scattering of clothing outside the casing. Moreover, the door body existing in the open position can be used for taking out the laundry. The handle portion for rotating the door between the closed position and the open position includes a first piece that is rotatably supported by the door body and a second piece that is extended by the first piece. The second piece is exposed to the outside of the casing when the door body is in the closed position. The user can use the second piece exposed outside the casing to rotate the door from the closed position to the open position. When the door body is in the closed position, the restriction surface of the support portion faces the housing. At this time, the first piece is located between the casing and the regulating surface. When the door body is rotated from the closed position toward the open position, the first piece abuts against the restriction surface, restricting the rotation of the handle portion. Therefore, even if the user is excessively strongly applied to the handle portion due to an erroneous operation, since the entire first piece contacts the support portion of the door body, it is possible to suppress the occurrence of high stress on the handle portion and/or the door body portion. Moreover, damage of the handle portion and/or the door body can be appropriately suppressed.

In the above configuration, it is preferable to have a locking mechanism for locking the door body to the closed position, and the locking mechanism can release the aforementioned closing position in conjunction with the rotation of the first piece close to the restriction surface. The locking of the door.

According to the above configuration, the locking mechanism that locks the door body to the closed position is interlocked with the rotation of the first piece close to the regulating surface of the door body, and the locking of the door body in the closed position is released. Therefore, interlocking the movement of the door body to the open position can unlock the door body. Moreover, it is possible to suppress the occurrence of excessive force due to the erroneous operation of the user.

In the above configuration, the housing body is formed with a locking hole, and the locking hole cooperates with the locking mechanism to lock the door body to the closed position. The locking mechanism has a locking arm, and the locking arm comprises: Rotatablely coupled to the base end portion of the door body, and when the door body is present in the closed position, inserted into the locking hole and engaged with the front end portion of the housing body, close to the limiting surface The first piece presses the base end portion of the lock arm, whereby the front end portion of the lock arm is released from the engagement position with the case by the engagement position with the case The door body is rotated from the closed position to the open position, whereby the locking arm is disengaged from the locking hole.

According to the above configuration, the housing is formed with a locking hole that cooperates with the locking mechanism to lock the door body to the closed position. The locking arm of the locking mechanism comprises: a base end that is rotatably coupled to the door body, and when the door body is in the closed position, is inserted into the locking hole and is engaged with the front end of the casing. When the proximal end portion of the lock arm is pressed by the first piece close to the restriction surface, the front end portion of the lock arm is rotated by the engagement position of the engagement with the housing to the release position where the engagement with the housing is released. Moreover, the locking mechanism can interlock with the rotation of the first piece of the support portion of the door body and release the locking of the door body in the closed position. Then, when the user rotates the door body from the closed position to the open position, the locking arm is disengaged from the locking hole. Therefore, excessive force due to erroneous operation of the user is suppressed.

In the above configuration, the detection unit for detecting the position of the door body and the processing tank housed in the housing body may further include: a support portion for supporting the locking mechanism, and the support portion a detecting arm protruding from the housing, wherein the housing is formed with a detecting hole for inserting the detecting arm when the door body is present in the closed position, and the detecting arm is configured by the detecting hole when the door body exists in an open position The detecting unit includes: a first detecting element for detecting the presence of the detecting arm in the detecting hole; and a control unit for controlling a rotation operation of the processing tank based on the presence or absence of the detecting arm in the detecting hole The control unit stops the rotation of the processing tank when the detection arm does not exist in the detection hole.

According to the above configuration, the detecting arm protrudes from the support portion that supports the locking mechanism. When the door body is present in the closed position, the detecting arm is inserted into the detecting hole formed in the housing. Further, when the door body exists in the open position, the detecting arm is disengaged from the detecting hole. Further, the detection unit can detect the position of the door by detecting the presence of the detection arm in the detection hole by the first detecting element. The control unit of the detecting unit stops the rotation of the processing tank when there is no detecting arm in the detecting hole. Therefore, when the door body exists in the open position, the rotation of the treatment tank is suppressed, so that the laundry treatment apparatus with high safety can be provided.

In the above configuration, the detecting unit preferably includes a second detecting element for detecting the presence or absence of the locking arm in the locking hole, wherein the detecting arm is not present in the detecting hole, and the lock is present in the locking hole When the arm is fixed, the control unit outputs information on the damage of the lock mechanism.

According to the above configuration, the detecting unit includes the second detecting element for detecting the presence or absence of the locking arm in the locking hole. When the detecting arm does not exist in the detecting hole, and the locking arm exists in the locking hole, the control unit outputs information about the damage of the locking mechanism. Moreover, it is possible to suppress the laundry treating apparatus from being operated under the damage of the locking mechanism, and to provide a laundry treating apparatus having high safety.

In the above configuration, the detecting arm is preferably integrally provided to the lock arm.

According to the above configuration, since the detecting arm is integrally provided to the lock arm, the detecting arm can be placed in a mechanical environment substantially equal to the lock arm. Therefore, the stress generated by the detecting arm can be easily maintained in a lower state than the locking arm that performs the engaging operation with the casing. therefore. The detection arm can be restrained from being damaged earlier than the locking arm, so that the detection accuracy of the damage to the locking mechanism can be improved. Moreover, the laundry treating apparatus can be inhibited from being operated under the damage of the locking mechanism, and the laundry treating apparatus having high safety can be provided.
