A tip of the suction hose is provided with a bath water sterilizing apparatus for sterilizing bath water described later.

  The drying mechanism 9 performs circulation ventilation and dehumidification of drying air for drying the laundry in the inner tub 3. Most of the drying mechanism 9 is occupied by a drying air circulation path.

  The drying air circulation path is connected so as to communicate with the bottom circulation path 20 connected so as to communicate with the bottom of the outer tub 2, the dehumidification vertical path 21 rising from the bottom circulation path 20, and the dehumidification vertical path 21. The warm air unit 22 is provided. The hot air unit 22 includes a blower fan and a heater 24, which will be described in detail later. The suction side of the hot air unit 22 is connected to the upper side of the dehumidifying vertical passage 21, and the discharge side is connected so that the return connection circuit 25 communicates.

  The return connection circuit 25 has an upper bellows hose 23 and is connected to communicate with the upper part of the outer tub 2 via the upper bellows hose 23. The bottom circulation path 20 also has a lower bellows hose 26 and is connected to communicate with the bottom of the outer tub 2 via the lower bellows hose 26.

  The dehumidifying vertical passage 21 has a dehumidifying area to be described later. The dehumidifying region exists in the dehumidifying vertical passage 21 so as to extend vertically. The drying air rising through the dehumidifying vertical passage 21 is cooled by bath water or tap water supplied to the dehumidifying region, and moisture contained in the drying air is taken away.

By the blower fan 29 of the hot air unit 22, the drying air passing through the drying air circulation path circulates in the inner tub 3 and dries the laundry in the inner tub 3. The drying air from which moisture has been removed in the dehumidifying region 8 is reheated and flows through the inner tub 3 by the heater of the warm air unit 22, so that moisture in the laundry is removed. By repeating this moisture removal with circulation of drying air, the laundry is dried well.

  The lower bellows hose 26 communicates with the washing water drainage channel 42 and the washing water circulation channel 43 through the lower communication pipe 41. A lower communication pipe 41 communicates with the washing water drainage path 42 via a drain valve 44, and a lower communication pipe 41 communicates with the washing water circulation water path 43 via a circulation pump 45 and a foreign matter removal trap 32.

  The drain valve 44 is closed during the washing operation and the drying operation. At the time of draining to drain the washing water or during the drying operation, the drain valve 44 is opened to drain the washing water and the rinsing water accumulated in the outer tub 2 to the outside of the washing dryer.

  The suction side of the circulation pump 45 is connected so as to communicate with the foreign matter removal trap 32. The discharge side of the circulation pump 45 is connected to communicate with the washing water circulation channel 43.

  Washing water and rinsing water collected in the outer tub 2 are sucked up by the circulation pump 45 and poured into the inner tub 3 from the washing thread waste removing device 33 through the washing water circulation water longitudinal water channel 46. Since the washing and rinsing are performed under the spray water injection by the circulation pump 45, washing and rinsing can be performed with a small amount of water.

  The water level sensor 47 detects the water level of the washing water and the rinsing water accumulated in the outer tub 2. An air trap 50 is provided near the bottom of the outer tub 2, and an air tube 49 connected so as to communicate with the air trap is provided. A water level sensor 47 is connected to the upper end of the air tube 49 so as to communicate therewith. The water level sensor 47 detects the water level fluctuation in the outer tub 2 to detect the water level.

  Next, individual features of the present invention will be described with reference to the drawings.

  First, the drying mechanism, dehumidifying means, and lint removal will be described with reference to FIGS.

  The drying air circulation path that occupies most of the drying mechanism 9 has a dehumidifying vertical passage 21. As shown in FIG. 5, the dehumidifying vertical passage 21 has cooling fins 72 included in the dehumidifying means in the dehumidifying region 70. The dehumidifying area 70 extends from the middle to the upper part of the dehumidifying vertical passage 21. The lower end of the dehumidifying area 70 is at a high water level (when the amount of washing is large).

  The cooling fins 72 of the dehumidifying means are formed of a metal material having good thermal conductivity such as stainless steel or aluminum. In addition, the cooling fin can be integrally formed of the same synthetic resin as that of the dehumidifying vertical passage 21. The cooling fins 72 are erected so as to protrude from the inner wall surface of the dehumidifying vertical passage 21. The drying air flowing from the bottom to the top of the dehumidifying vertical passage 21 rises while touching the cooling fins 72 to perform dehumidification.

  The cooling water supply connection port 80 is provided in the dehumidifying vertical passage 21. The supply connection port 80 is connected to a cooling water supply tube for supplying a bath water pump sucked up by tap water or a bath water pump. The cooling water passes through the supply connection port 80 and goes down the dehumidifying vertical passage 21 while being transmitted through the cooling fins 72. Here, the drying air that goes up the dehumidifying vertical passage 21 from below is cooled by touching the cooling water or the cooling fins 72, and moisture contained in the drying air is taken away.

  The cleaning water supply connection port 81 is provided adjacent to the cooling water supply connection port 80. The supply connection port 81 is connected to a cleaning water cooling water supply tube that supplies a bath water pump sucked up by tap water or a bath water pump. The washing water passes through the washing water supply connection port 81 and goes down the dehumidifying vertical passage 21 while being transmitted through the cooling fins 72. The lint, cloth waste, etc. adhering to the cooling fin 72 and the inner wall surface of the dehumidifying vertical passage 21 are removed by being washed away with washing water.

  The defoaming nozzle 82 is provided above the dehumidifying vertical passage 21. The defoaming nozzle 82 is placed so that the tip thereof is inclined downward. A defoaming water supply tube 83 is connected to the defoaming nozzle 82. Although not shown, the defoaming water supply tube 83 is connected to communicate with the washing water circulation water longitudinal water channel 46. Defoaming water is sprayed from the defoaming nozzle 82 during the washing operation and the rinsing operation.

  With this defoaming water, the detergent bubbles that go up the dehumidifying vertical passage 21 during the washing operation and the rinsing operation are eliminated. The detergent bubbles rising while increasing the dehumidifying vertical passage 21 are eliminated.

  The dehumidifying vertical passage 21 has a rectangular cross section. The dehumidifying vertical passage 21 has a shape with a narrow width in the front-rear direction and a wide width in the horizontal direction, which is related to the location of the dehumidifying vertical passage 21. The dehumidifying vertical passage 21 is placed between the outer tub 2 and the outer frame 1 on the rear side of the washing / drying machine. Since the space between the outer tub 2 and the outer frame 1 is narrow on the rear side of the washing / drying machine, the dehumidifying vertical passage 21 has the above-described shape.

  Although the outer frame 1 has a quadrangular shape, hanging rods that hang down the outer tub 2 are placed at the four corners. Therefore, the dehumidifying vertical passage 21 is arranged on the rear side of the washing / drying machine.

  The dehumidifying vertical passage 21 having the above shape has an extended air passage portion 84 on the upper side. The extended air passage portion 84 is formed by extending the width in the horizontal direction to one side above the height 2/3 of the vertical passage 21 for dehumidification. The upper end lateral width of the dehumidifying vertical passage 21 is about twice the lower end lateral width. Moreover, the extended wind path part 84 becomes the inclination shape which expands a horizontal width toward upper direction.

  The upper end of the dehumidifying vertical passage 21 has a drying air outlet 86 through which drying air flows in a portion of the extended air passage portion 84, and a cooling water flow lower portion 85 is provided in other portions except the extended air passage portion 84. Have. The cooling water supplied from the cooling water supply connection port 80 flows down from the flow lower portion 85, travels along the cooling fin 72, and goes down the dehumidifying vertical passage 21.

  The drying air rises from the dehumidifying vertical passage 21 from below, leaves the contact with the cooling water at the extended air passage portion 84, and flows toward the hot air unit 22 and a drying filter described later.

  By the extended air passage portion 84, it is possible to prevent water droplets of cooling water from flowing into the hot air unit 22 and the drying filter.

  That is, when the drying air outlet 86 is provided in the cooling water flow lower portion 85 without providing the expansion air passage portion 84, the water droplets of the cooling water flowing down from the flow lower portion 85 and jumping off by the cooling fins 72 become the drying air. There is a possibility of riding and flowing into the hot air unit 22 or the drying filter.

  However, by providing the extended air passage portion 84, the drying air coming up from the bottom of the dehumidifying vertical passage 21 is separated from the contact with the cooling water at the extended air passage portion 84. For this reason, the drying air escapes before passing through the place where the cooling water flowing down from the lower portion 85 jumps at the cooling fins 72.

  Further, the flow passage cross-sectional area of the dehumidifying vertical passage 21 is much larger when the extended air passage portion 84 is present than when the lower extended air passage portion 84 is not present. For this reason, the flow of the drying air becomes more gentle, and the momentum for carrying the cooling water droplets is lost.

  As described above, by providing the extended air passage portion 84, the drying air does not carry the cooling water droplets, so that the cooling water droplets flow into the hot air unit 22 or the drying filter. Can be suppressed.

  Further, during the washing operation or the rinsing operation, even if the defoaming nozzle 82 is not sufficiently defoamed and the detergent foam rises up the dehumidifying vertical passage 21, the dehumidifying vertical passage 21 remains at the extended air passage portion 84. Since the cross-sectional area increases, the rise of the detergent foam is suppressed here. Thereby, the malfunction that detergent foam flows into warm air unit 22 or a dry filter is prevented beforehand.

  The dehumidifying vertical passage 21 has a lint removal window 90 as shown in FIGS. The lint removal window 90 is provided in the extended air passage portion 84 facing the outer frame 1. The window lid 91 is detachably provided on the lint removal window 90. The window lid 91 is fastened and fixed by the set screw 92.

  As shown in FIGS. 8, 9, 10, and 11, the outer frame 1 has an outer window 93 at a position facing the lint removal window 90. The outer lid 94 is detachably provided on the outer window 93. The outer lid 94 is fastened and fixed by the outer set screw 95. The outer circumference of the outer window 93 is larger than the outer periphery of the window lid 91 as shown in FIG.

  In the drying operation, the drying air circulates through the dehumidifying vertical passage 21. Lint such as lint that circulates on the drying air is collected by a drying filter, which will be described later, but also accumulates in the extended air passage portion 84 where the flow of the drying air becomes gentle.

  It is desirable to remove the lint accumulated in the expanded air passage portion 84. The external set screw 95 is loosened, the external lid 94 is removed, the set screw 92 is loosened, and the window lid 91 is removed. Then, the lint accumulated in the expanded air passage portion 84 is removed by putting a hand through the outer window 93 and the lint removal window 90. By attaching the window lid 91, tightening the set screw 92, attaching the outer window 93, and tightening the external set screw 95, the maintenance related to the removal of lint accumulated in the extended air passage portion 84 is completed.

  In this manner, the lint accumulated in the expanded air passage portion 84 can be easily removed from the outside of the outer frame 1 of the washing / drying machine by removing the outer lid 94 and the window lid 91, so that maintenance is easy. Further, since the outer circumference of the outer window 93 is larger than the outer periphery of the window lid 91, the window lid 91 can be taken out of the outer frame 1 through the outer window 93. Since the window lid 91 is completely removed and lint can be removed and cleaned, cleaning is easy.

  The dry filter (dry filter device) will be described with reference to FIGS.

  The drying filter (drying filter device) 100 is provided so as to be interposed in the drying air circulation path of the drying mechanism 9. The dry filter (dry filter device) 100 functions as dry lint removing means for collecting and removing lint carried by the drying air flowing through the drying air circulation path. The drying filter device 100 is placed between the drying air outlet 86 of the dehumidifying vertical passage 21 and the upstream side (suction side) of the hot air unit 22.

  As shown in FIG. 15, the dry filter device 100 includes a main body frame 101 and a dry filter frame 102 that can be pulled out and pushed into the main body frame 101. The dry filter frame 102 has a front frame 103 and a filter frame 104. The filter frame portion 104 includes an inlet 106 through which drying air flows into the rear portion, and a filter 107 that collects lint on the upper surface.

  The front panel 108 of the front frame portion 103 has a notch-shaped handle 109 at the bottom. The grip 109 is grasped, and the dry filter frame 102 is taken in and out of the main body frame 101.

  The dry filter frame 102 is provided with retaining means 110 on both side surfaces of the front frame portion 103. With the retaining means 110, the dry filter frame 102 pushed into the main body frame 101 is held so as not to come out.

  As shown in FIGS. 16, 17, 18, and 20, the retaining means 110 includes a non-slip member 111 made of rubber, a push pin 112, and a fixing member 113. The non-slip member 111 has a spherical head portion 114 on the front side, an annular flange 115 on the outer periphery on the rear side, and a recess 116 that is recessed from the rear side toward the front side.

  The fixing member 113 has a receiving portion 117 that receives the rear portion of the push pin 112 in the center, and a pair of locking claws 118 on the outer peripheral side.

  As shown in FIGS. 17 and 21, the front frame portion 103 has a pair of engagements in which the through holes 119 into which the heads 114 of the non-slip members 111 are fitted and the locking claws 118 of the fixing members 113 are engaged on both side surfaces. A groove 120 is provided. The pair of engagement grooves 120 are arranged and formed around the through hole 119 and have an arc shape.

  As shown in FIG. 21, the engagement groove 120 has a through groove portion and a non-through groove portion. The through-groove portion is sized so that the locking claw 118 of the fixing member 113 can be inserted. The locking claw 118 is engaged with the remaining non-penetrating groove. The groove depth of the non-penetrating groove portion is desirably such that the engaged locking claw 118 is not exposed from the engaging groove 120 or slightly exposed even when exposed (FIG. 18).

  As shown in FIG. 19, the retaining means 110 is assembled from the inside of the front frame portion 103. The non-slip member 111 is inserted into the through hole 119 from the head 114. Subsequently, the fixing member 113 is attached after the push pin 112 is inserted into the recess 116 of the non-slip member 111. The fixing member 113 is engaged so that the locking claw 118 rides on the non-penetrating groove portion of the engaging groove 120 by rotating the locking claw 118 after being inserted into the through groove portion of the engaging groove 120. Installation is performed.

  Now, in a state where the dry filter frame body 102 is pushed into and attached to the main body frame body 101, the anti-slip member 111 protruding from the side surface of the dry filter frame body 102 is pressed against the inner wall surface of the main body frame body 101. The non-slip member 111 is pressed by distorting the head 114 by elastic deformation of rubber. The frictional force of the rubber due to the elastic deformation strongly acts to prevent slipping, and the dry filter frame 102 is held so as not to come out of the main body frame 101.

  Further, since the anti-slip member 111 is pressed from the inside by the push pin 112, the head 114 is strongly pressed against the inner wall surface of the main body frame 101, and the anti-slip action due to strong friction is maintained. For this reason, the attachment of the drying filter frame 102 does not loosen or come off due to the operating vibration of the washing / drying machine.

  Further, the mounting and holding of the dry filter frame 102 is based on an anti-slip action due to friction of the anti-slip member 111. In addition, since the dry filter frame 102 is detached and attached by the pulling / pushing operation of the dry filter frame 102, the attachment / detachment operation is easy, unlike a mechanical clamping mechanism that involves a rotation operation.

  Further, the retaining means 110 is assembled by simply inserting the anti-slip member 111 and the push pin 112, inserting the locking claw 118 of the fixing member 113 into the engaging groove 120, and twisting it, so that assembly is easy. is there.

  Furthermore, the locking claw 118 engaged with the engaging groove 120 is not exposed from the engaging groove 120, or only slightly when exposed. For this reason, even if the head 114 of the anti-slip member 111 is distorted, the locking claw 118 does not come into contact with the inner wall surface of the main body frame 101. Maintained.

  In the above embodiment, the retaining means 110 is provided on the dry filter frame 102 and the slip preventing member 111 of the retaining means 110 is slidably contacted with the inner wall surface of the main body frame 101. Can be replaced with the main body frame 101. That is, if the anti-slip member 111 is configured to be in sliding contact with one opposing surface (for example, the inner wall surface of the main body frame 101) where the main body frame 101 and the dry filter frame 102 face each other, the dry filter frame body 102 is removed. Stop can be realized.

  The hot air unit will be described with reference to FIGS. 12, 13, and 14. FIG.

  The warm air unit 22 includes a front side unit case 200, a back side unit case 201, a blower fan 202, and a heater 24 for heating. A unit case is formed by combining the front unit case 200 and the back unit case 201. A blower fan 202 and a heater 24 for heating are placed inside the unit case. The heater 24 uses a PTC thermistor. The rod-like long PTC thermistor heater 24 generates heat uniformly throughout and heats the air blown from the blower fan 202 that is in contact with a large number of fins and circulates.

  The front-side unit case 200 and the back-side unit case 201 have a casing portion 204 in which the blower fan 202 is placed, and a heater chamber 205 in which the heater 24 is placed. The blower fan 202 is a turbo fan and rotates at high speed in the direction of arrow P. The blades 212 of the turbo fan have an arc shape, and the twelve blades 212 are arranged at an equal pitch. The blower fan 202 is driven by an electric motor. The blower fan 202 and the electric motor are collectively referred to as an electric blower.

  The front unit case 200 has a suction port 206 and a discharge port 207. The suction port 206 is located at the center of the casing portion 204 so as to face the suction side center of the blower fan 202. The discharge port 207 is disposed at the position of the heater chamber 205 on the downstream side of the heater 24. The suction port 206 communicates with the dehumidifying vertical passage 21 via the drying filter (drying filter device) 100. The discharge port 207 communicates with the connection circuit 25 of the drying air circuit.

  The casing unit 204 has a discharge port 208. The discharge port 208 has a rear end portion 209 that becomes the rear side and a front end portion (nose portion) 210 on the front side with respect to the rotation direction of the blower fan 202. The rear end 209 is close to the outer periphery of the blower fan 202. The rear end 209 is separated from the outer periphery of the blower fan 202. Therefore, the gap between the inner periphery of the casing portion 204 and the outer periphery of the blower fan 202 has an involute shape that gradually increases from the rear end portion 209 toward the nose portion 210.

  The flow rate distribution discharged from the discharge port 208 by the rotation of the blower fan 202 is non-uniform with a large number of the rear end portions 209 and a small nose portion 210. Therefore, in order to make the flow distribution close to be uniform, a raised portion 211 that protrudes toward the nose portion 210 so as to narrow the discharge port 208 is provided on the rear end portion 209 side. The raised portion 211 is located between the rear end portion 209 and one end portion of the heater 24 and has a shape in which the center facing the rear end portion 209 is raised higher.

  As described above, the discharge port 208 is provided with the raised portion 211 that protrudes so as to narrow the discharge port 208 toward the nose portion 210 at the rear side end portion 209 located on the opposite side of the nose portion 210, so that the heater 24 is provided. Since the rear end portion 209 and the nose portion 210 are made to approach uniformly, the heating range of the heater 24 is leveled as a whole, and the dry air is heated well.

  The removal of static electricity will be described with reference to FIGS.

  The outer tub upper cover 300 attached to and supported by the upper end edge of the outer tub 2 has a ring-shaped cover portion 301 and a semicircular cover portion 302. The ring-shaped cover portion 301 covers the front upper side of the outer tub 2 and the inner tub 3 except for the rear portion. The semicircular cover portion 302 covers the rear upper side of the outer tub 2 and the inner tub 3. The ring-shaped cover portion 301 is a laundry entrance / exit 303 having a large opening on the inner peripheral side. The entrance 303 is opened and closed by the inner lid 34.

  The ring-shaped cover portion 301 and the semicircular cover portion 302 are integrally formed using an SPS (synthetic resin) material. Conventionally, the cover portion 301 and the cover portion 302 are formed of a pressed product made of stainless steel. Since it was made into a molded product of SPS (synthetic resin) material, the productivity was remarkably improved and the weight was reduced. Further, since the SPS (synthetic resin) material is excellent in moldability and heat resistance, it withstands high temperatures during drying operation.

  The inner lid 34 is supported on the outer tank upper cover 300 by a hinge 304 so as to be opened and closed. The inner lid 34 has a reinforcing frame 305 made of stainless steel casket, a lid cover 306 made of synthetic resin, and a transparent window 307 made of heat-resistant glass. The lid cover 306 and the reinforcing frame 305 are tightened and fastened with screws 308, and the transparent window 307 is sandwiched between the lid cover 306 and the reinforcing frame 305.

  One end of a static elimination lead member 309 made of metal (stainless steel) or a material that conducts electricity, a reinforcing frame fastened to a boss portion 310 of a lid cover 306 with a screw 317 as shown in FIGS. Closed with 305. The other end of the lead member 309 is fastened and fastened to the lead boss 311 with a lead screw 312. The lead screw 312 is made of metal (stainless steel) or a material that conducts electricity.

  The thin sheet conductive rubber member 313 is provided in the vicinity of the hinge 304 of the outer tub upper cover 300. As shown in FIGS. 25 and 27, the conductive rubber member 313 and the lead screw 312 are provided in the vicinity of the rotation shaft 314 provided in the hinge 304. For this reason, as shown in FIGS. 27 and 28, the lead screw 312 is separated from the conductive rubber member 313 when the inner lid 34 is opened. When the inner lid 34 is closed, as shown in FIGS. 25 and 26, the head of the lead screw 312 comes into contact with the conductive rubber member 313 and is electrically connected thereto.

  One end of an external lead member 315 made of a metal (stainless steel) or a material that conducts electricity is connected to the conductive rubber member 313 and fixed to the outer tank upper cover 300 together with the conductive rubber member 313. A connection terminal 316 is provided at the other end of the lead member 315, and is grounded to the outer frame 1 through the connection terminal 316.

  When the laundry is stirred by the stirring blade 4 during the drying operation, moves around in the inner tub 3, and the laundry with static electricity comes into contact with the inner lid 34, the static electricity is the inner lid 34, the lead member 309, the lead screw 312, the conductive rubber. It is discharged to the outer frame 1 via the member 313 and the lead member 315.

  Such discharge discharges static electricity from the laundry during the drying operation, so that it is possible to eliminate an electric shock when the laundry is taken out after the drying operation.

  In the static elimination mechanism, the lead screw 312 for stopping the lead member 309 provided on the inner lid 34 is provided in the vicinity of the rotating shaft 314 of the hinge 304, and the head of the lead screw 312 is opened and closed according to the opening and closing of the inner lid 34. The conductive rubber member 313 that contacts and separates is provided on the outer tank upper cover 300. In this configuration, unlike the case where the inner lid side and the outer tub upper cover side are connected by a lead wire, damage due to repeated bending of the lead wire accompanying opening and closing of the inner lid does not occur. Further, since the lead screw 312 and the conductive rubber member 313 are provided in the vicinity of the rotating shaft 314 of the hinge 304, they are not exposed to the outside unlike those provided at a position away from the hinge 304. Therefore, there is no possibility that the laundry touches the lead screw 312 or the conductive rubber member 313 and is damaged when the laundry is taken in and out.

  The bath water sterilization apparatus will be described with reference to FIGS.

  The bath water sterilizer 400 is connected to the tip of a suction hose extending from a bath water pump (not shown). Since the bath water is sucked into the washing and drying machine through the bath water sterilizing apparatus 400, clean washing with the sterilized bath water can be performed.

  The bath water sterilization apparatus 400 includes a sterilization cassette 401, an upstream foreign matter removal filter 402, a downstream foreign matter removal filter 403, a suction cap 404, a filter holder 405, and a main body weight 406. The main body weight 406 is made of a heavy material that sinks in water, and a suction hose is screwed to the rear portion and a suction cap 404 is screwed to the front side. The sterilization cassette 401, the upstream foreign matter removal filter 402, the downstream foreign matter removal filter 403, and the filter retainer 405 are accommodated in the suction cap 404.

  The sterilization cassette 401 includes a cylindrical body 407 made of a synthetic resin, a granular bactericidal agent (not shown) packed inside the cylindrical body 407, and a synthetic resin cassette lid 408 that traps the granular bactericidal agent. The cylindrical body 407 has a partition portion 409 having a large number of water passage holes (water passage holes smaller than the particle diameter of the granular bactericide) at the inner center.

  The partition 409 divides the inside of the cylindrical body 407 into two chambers in the axial direction. The partition portion 409 is formed integrally with the cylindrical body 407. The partition portion 409 has a large number of water holes (water holes smaller than the particle diameter of the granular sterilizing agent).

  The two chambers are provided with a plurality of columns 410 extending from the partition portion 409 to the vicinity of the mouth edge of the cylindrical body 407. In addition, a plurality of support columns 410 are provided in the center of the partitioning portion 409 and four in the periphery. It is also possible to provide more than this.

  The cassette lid 408 has a large number of water passage holes (water passage holes smaller than the particle diameter of the granular bactericide), and the outer periphery fits inside the cylindrical body 407. When the cassette lid 408 is fitted, it is received by the tips of the plurality of columns 410. Further, the cassette lid 408 is stopped by the engaging means of the cassette lid so as not to easily fall off.

  The place where the sterilization cassette 401 becomes an effective sterilization cassette is a place where a granular sterilizing agent is filled and partitioned by the cassette lid 408 and the partitioning part 409. The outer surface side of the cassette lid 408 becomes the upstream end surface of the sterilization cassette into which bath water flows into the sterilization cassette. The outer surface side of the partition part 409 becomes the downstream end surface of the sterilization cassette from which the bath water sterilized from the sterilization cassette flows out.

  Now, the bath water that has passed through the water passage hole of the suction cap 404 and entered the bath water sterilization apparatus 400 is removed by the upstream foreign matter removal filter 402 and sterilized by the granular sterilizing agent in the sterilization cassette 401. . Then, the sterilized bath water free from foreign matters from which foreign matters have been further removed by the downstream side foreign matter removing filter 403 can be provided to the washing and drying machine.

  Since the upstream foreign matter removal filter 402 is placed so as to be sandwiched between the cassette lid 408 and the inside of the suction cap 404, the state is maintained. Therefore, since there is no position shift, foreign matter removal by the upstream side foreign matter removal filter 402 is often performed.

  Since the downstream foreign matter removal filter 403 is placed so as to be sandwiched between the plurality of columns 410 and the filter retainer 405, the state is maintained. For this reason, since there is no displacement, foreign matter removal by the downstream foreign matter removal filter 403 is often performed.

  Further, the downstream foreign matter removal filter 403 also has a function of capturing a granular sterilizing agent. When the granular germicide flows out from the sterilization cassette 401, the particulate germicide is captured by the downstream foreign matter removal filter 403. There are many types of granular fungicides. Particles of metal, glass, etc., formed by adsorption, inclusion, mixing, etc. of silver ions.

  Even if these hard particle disinfectants flow out of the sterilization cassette 401, they are captured by the downstream foreign matter removal filter 403, and the runner provided in the bath water pump is prevented from being damaged.

  Further, the foreign matter removal pores of the downstream foreign matter removal filter 403 are smaller than the foreign matter removal pores of the upstream foreign matter removal filter 402. Therefore, the fine foreign matter that has not been removed can be removed by the upstream foreign matter removal filter 402.

  When the disinfection effect of the granular bactericidal agent is lowered, the granular bactericidal agent is refilled. The cassette lid 408 of the sterilization cassette 401 is locked by the engaging means. For this reason, the cassette lid 408 is not easily detached by removing / attaching the sterilization cassette 401 from the bath water sterilization apparatus 400, and the detachment operation is easy.

  Further, when the cassette lid 408 is attached by refilling the granular sterilizing agent, it is easy to assemble because the engaged cassette lid 408 is engaged by the engaging means at a position where it is received by the tips of the plurality of columns 410.

  Furthermore, the sterilization effect and flowability of the bath water sterilization apparatus will be described with reference to FIG. 29 and FIG.

  The diameter Φ1 of the cylindrical body 407 that is the sterilization cassette 401 is about 38 mm. The diameter [Phi] 2 of the narrow flow passage connected to the downstream passage through which the bath water sterilized after passing through the sterilization cassette 401 flows is about 12 mm. The diameter Φ2 of the narrow channel leads to the suction hose.

  The length D1 of the upstream gap, which is the facing gap where the outer surface of the cassette lid 408, which is the upstream end surface of the sterilization cassette 401, and the upstream foreign matter removal filter 402 face each other is about 5 mm. The length D2 of the downstream gap, which is the facing gap where the outer surface of the partition 409, which is the downstream end face of the sterilization cassette 401, and the downstream foreign matter removal filter 403 face each other is about 15 mm. The downstream passage through which the bath water sterilized by the sterilization cassette 401 flows is gradually narrowed from the middle, and is connected so as to communicate with a narrow channel having a diameter Φ2 when the taper stops.

  The length D3 from the position where the downstream passage starts to become narrow to the downstream end face of the sterilization cassette 401 is about 30 mm. The length D4 from the upstream end face (outer face of the cassette lid 408) to the downstream end face (outer face of the partition portion 409) of the sterilization cassette 401 is about 15 mm.

  The length D2 from the downstream end surface of the sterilization cassette 401 (the outer surface of the partition 409) to the upstream end surface of the downstream foreign matter removal filter 403 is about 15 mm. A length D5 from the position where the downstream passage starts to become narrow to the downstream end face of the downstream foreign matter removal filter 403 is about 10 mm. The length D6 of the range in which the downstream side passage becomes narrower is about 10 mm.

  The clearance between the upstream end face of the sterilization cassette 401 and the upstream foreign matter removal filter 402 is provided with a gap having a width D1 (about 5 mm) because the remaining water from the bath water sterilization apparatus 400 and the suction hose is removed. This is to remove it.

  The clearance between the downstream end face of the sterilization cassette 401 and the downstream foreign matter removal filter 403 is provided with a gap having a width D2 (about 15 mm) in order to drain the remaining water from the bath water sterilization apparatus 400 and the suction hose. It is.

  If the sterilization cassette 401 and the upstream / downstream foreign matter removal filter are too close to each other, a water film is generated between the sterilization cassette 401 and the air flow is blocked, and the water remaining in the bath sterilization apparatus 400 cannot be drained. Therefore, by providing a gap between the sterilization cassette 401 and the upstream / downstream foreign matter removal filter so as not to generate a water film, the air flow is not blocked and the remaining water can be drained.

  If the residual water is retained in the bath water sterilization apparatus 400, the sterilizing components are dissolved from the sterilizing agent in the sterilization cassette 401, so that the sterilization effect is rapidly reduced. Moreover, if the dissolved high-concentration sterilizing component adheres to the clothes being washed, the fabric may be discolored. By draining the water remaining in the bath water sterilization apparatus 400, it is possible to solve the problems of early deterioration of the sterilization effect and discoloration of clothing. As for the effect of draining residual water, it is more effective to secure a clearance on the upstream / downstream side foreign matter removal filter side. Further, as shown in FIG. 32, the cassette lid 408 has an annular ring that rises in front of the outer surface in which a large number of water passage holes are provided in the outer peripheral edge portion. By this annular ring, the upstream foreign matter removal filter 402 is received, and a gap can be maintained between the outer surface of the cassette lid 408 (the upstream end surface of the sterilization cassette 401). It is possible to maintain the gap with such a simple configuration.

  FIG. 60 is a graph showing the flowability.

  This graph shows the length D3 from the position where the downstream passage starts to become narrower to the downstream end surface of the sterilization cassette 401 when the length D4 from the upstream end surface to the downstream end surface of the sterilization cassette 401 is 15 mm. The amount of water per minute flowing through the sterilization cassette 401 was shown by changing the range from 0 mm to 30 mm. This amount of 9 L / min is equivalent to that of a conventional bath water supply device (strainer) that does not include a sterilization cassette.

  From this graph, it can be seen that when the length D3 is shorter than the length D4 (15 mm), the amount of water flowing through the sterilization cassette 401 decreases. Since bath water is supplied to the washing machine via the bath water sterilization apparatus 400, when the circulation amount of the sterilization cassette 401 decreases, the water supply time for washing and rinsing becomes longer.

  Therefore, by setting the relationship between the length D3 and the length D4 to (D3> D4 or D3 = D4), even if a sterilization cassette 401 for sterilizing bath water is provided, a conventional bath water supply device (strainer) A distribution volume equivalent to Thereby, the bath water disinfection apparatus which can disinfect bath water without extending the water supply time of washing and rinsing can be provided.

  The waste thread removal device, the foreign matter collecting trap, and the shower cleaning will be described with reference to FIGS. 33 to 43, 2, and 3.

  As shown in FIGS. 1 to 3 and FIGS. 33 to 36, the laundry waste removal device 33 is provided on the upper side of the inner tub 3, that is, on the lower surface of the cover portion 302 of the outer tub upper cover 300. As shown in FIGS. 37 to 41, the laundry thread waste removing device 33 includes a laundry thread waste collecting case 500 and a holding case 501 that holds the laundry waste thread collecting case 500.

  By screwing the holding case 501 to the lower surface of the cover portion 302, the washing thread waste removing device 33 is fixed to the outer tub upper cover 300 as shown in FIG. As shown in FIG. 37, the holding case 501 has a screw boss portion 502 through which a set screw is passed.

  The waste thread collecting case 500 is detachably attached to the holding case 501. Like a drawer, the waste thread collecting case 500 is slid back and forth and is detachably attached to the holding case 501.

  As shown in FIGS. 37 and 38, the waste thread collecting case 500 includes a peripheral wall 504 that rises from the bottom 503. The laundry waste collection basket 505 is detachably placed in the peripheral wall 504. The basket lid 506 is detachably attached to the laundry thread collecting basket 505. The holding case 501 has a lid pressing rib 507 that hangs down.

  The lower end of the rib 507 is slidably in contact with the upper surface of the car lid 506. The car lid 506 is pressed from above by the ribs 507 when the washing thread waste collecting case 500 is attached to the holding case 501, so that the car lid 506 does not come off due to vibration of washing operation or inflow of circulating washing water.

  The holding case 501 has an inlet 508 for injecting circulating washing water. The circulating washing water poured from the inlet 508 is poured into the inner tub 3 from the shower port 509 through the laundry waste collection basket 505. The circulating washing water flowing from the inlet 508 has an inlet 510 provided in the car lid 506.

  One shower port 509 is circular and is provided downward. The diameter of the circular shower port 509 is about 19 mm, preferably about 30 mm to 10 mm.

  The rib 507 also serves as a weir that guides the circulating washing water flowing from the inlet 508 to the inlet 510. The outflow of the circulating washing water to other than the inflow port 510 is blocked by the ribs 507, so that the lint contained in the circulating washing water is often performed. Since the car lid 506 has a groove in which the lower end of the rib 507 is fitted, the damming is further improved.

  The holding case 501 has a seal packing 511 provided on the lower surface so as to face the peripheral wall 504 (shown in FIG. 27). Since the upper end of the peripheral wall 504 is in close contact with the seal packing 511 and seals the flow of water, the circulating washing water poured into the washing thread waste collecting case 500 can be guided to the shower port 509 without leaking to others. .

  The shower port 509 is provided at the center bottom of the shower inflow chamber 540 surrounded by a circular peripheral wall 504. The shower inflow chamber 540 has an inflow port 541 on the side. The width of the inflow port 541 is circular and narrower than the shower inflow chamber 540, and is about ¼ of the diameter of the shower inflow chamber 540. The direction of the inflow port 541 is eccentric with respect to the center of the shower port 509 so as to be along the tangential direction of the inner peripheral wall surface of the shower inflow chamber 540. The introduction water channel 542 upstream of the inflow port 541 has a shape that narrows toward the inflow port 541.

  The washing water flowing into the shower inflow chamber 540 swirls within the shower inflow chamber 540 because the inflow port 541 is in the tangential direction of the inner peripheral wall surface of the shower inflow chamber 540. Moreover, since the introduction water channel 542 is narrowed toward the inflow port 541, a swirling flow with a fast flow is obtained.

  The waste thread collecting case 500 has a handle 512 on the front side as shown in FIGS. 33 to 37 and 39 to 41. The handle 512 is rotatably supported by the laundry waste collection case 500. At both ends of the handle 512, groove engaging portions 513 are provided. The holding case 501 has a pair of protruding ribs 514 opposed to both ends of the handle 512 on the front side. A locking portion 515 for locking the engaging portion 513 of the groove is provided on the protruding rib 514.

  The center of the handle 512 is pivotally supported on the front side of the waste thread collecting case 500, but it is also possible to provide a pivot fulcrum at an offset position deviating from the center.

  The handle engaging means constituted by the engaging portion 513 and the locking portion 515 is engaged / disengaged by twisting the handle 512. In the engagement, when the handle 512 is rotated in the clockwise direction, the engaging portion 513 and the locking portion 515 are engaged as shown in FIG. By rotating the handle 512 in the counterclockwise direction, the engaging portion 513 is detached from the locking portion 515 and separated as shown in FIG.

  That is, the handle 512 is engaged with the handle engaging means in the horizontal state shown in FIG. 33, and the handle engaging means is separated in the inclined state shown in FIGS.

  To clean the laundry waste collection case 500, the handle 512 is twisted to disengage the engagement of the handle engaging means by the engagement of the engaging portion 513 and the engaging portion 515, and the laundry waste collection case 500 is removed. Is removed from the holding case 501. When cleaning is completed, the waste thread collecting case 500 is attached to the holding case 501. Then, by twisting the handle 512 to engage the engaging portion 513 and the locking portion 515 and engaging the handle engaging means, the attachment of the waste thread collecting case 500 is completed.

  Since the handle 512 of the washing thread waste collecting case 500 is restrained from being twisted during the operation of the washing / drying machine, the washing waste thread collecting case 500 is prevented from being removed.

  As described above, the inner lid 34 is supported on the cover portion 302 of the outer tub upper cover 300 by a hinge 304 so as to be freely opened and closed. The inner lid 34 is pivotally opened and closed so that the front side can be raised and lowered with the rear side freely supported by the hinge 304. A handle 512 of the waste thread collecting case 500 is provided so as to be positioned near the lower rear side of the inner lid 34 (shown in FIGS. 33 to 36).

  When the inner lid 34 is closed, the rear lower surface of the inner lid 34 comes close to the upper surface of the handle 512 as shown in FIG. The twisting operation of the handle 512 is constrained near the rear lower surface of the inner lid 34. Due to the restriction of the twisting operation, the engagement of the handle engaging means is not released. For this reason, even if the laundry that moves in the inner tub 3 collides with the handle 512 during the operation of the washing / drying machine, the engagement of the handle engaging means is not released, and the washing thread waste collecting case 500 is naturally removed. Is prevented.

  As shown in FIGS. 33 to 35, when the inner lid 34 is opened, the twisting restraint of the handle 512 is released. Therefore, the handle engaging means is disengaged and the laundry waste collecting case 500 is removed. Can be cleaned.

  The twisting restraint of the handle 512 is defeated by a twisting restraining mechanism (twisting restraining means) constructed in connection with the opening / closing operation of the inner lid 34, and is compared with that using a complicated mechanical mechanism. The structure is very simple, and it is easy to use because it can restrain and release the twisting of the handle 512 only by opening and closing the inner lid 34.

  In the above embodiment, the outer lid is pivotally supported by the outer tub upper cover 300 so that the front side operates up and down, and the outer lid 34 opens and closes the laundry entrance / exit 303. This is a washing machine having a washing thread waste removing device 33 provided on the lower surface of the tank upper cover 300 and having a washing thread waste collecting case 500 held in and out of a holding case 501.

  In this washing machine, the washing thread waste removing device 33 is supported by the washing thread waste collecting case 500 so as to be freely twisted about the center as a pivot, and is engaged with and separated from the holding case 501 by the twisting operation. The handle 512 has a handle 512 to be engaged. The handle 512 closes the inner lid 34 when the inner lid 34 is closed to restrain the twisting operation, and the inner lid 34 is released when the inner lid 34 is opened. It is the structure provided in the related position.

  When the inner lid 34 is closed, the inner lid 34 approaches to restrain the twisting operation, and when the inner lid 34 is opened, the configuration provided at the position related to the inner lid 34 is followed so that the restraint is released. For example, the arrangement position of the laundry waste removal device 33 and the fulcrum position where the inner lid 34 is pivotally supported can be selected as appropriate.

  The foreign substance removal trap and the circulation pump are shown in FIGS.

  The foreign matter removal trap 32 includes a trap outer case 520 and a trap inner case 521.

  The inlet 522 of the trap outer case 520 communicates with the lower communication pipe 41. A discharge port 523 of the trap outer case 520 communicates with the circulation pump 45.

  The trap inner case 521 has a foreign substance removal trap portion 524 inserted into the trap outer case 520 and a knob portion 525 provided on the front side. By grasping the knob 525, the trap inner case 521 is taken in and out of the trap outer case 520. The trap inner case 521 is provided with a bayonet attachment / detachment mechanism that can be attached and detached by twisting. The front doorway of the trap outer case 520 is provided with a seal packing to prevent water leakage from a joint portion with the trap inner case 521 to be mounted.

  The foreign substance removal trap portion 524 of the trap inner case 521 has a cylindrical shape having an inlet at the rear and a small hole 526 at the front peripheral portion. The foreign matter flowing into the foreign matter removal trap portion 524 from the inlet is trapped because the outlet is a small hole 526 provided in the front peripheral portion. For this reason, washing water from which foreign matter has been removed is supplied to the circulation pump 45 to protect the circulation pump 45 from foreign matter.

  The circulation pump 45 includes a centrifugal pump unit including a pump casing 527 and a pump runner 5229, and an electric motor 530 for driving. A suction port 528 of the pump casing 527 communicates with the foreign matter removal trap 32. A discharge port 535 of the pump casing 527 communicates with the washing water circulation channel 43.

  As the electric motor 530, a variable speed electric motor driven by a DC inverter whose rotational speed can be changed is used. The rotational speed of the pump runner 529 is changed by changing the speed of the electric motor 530, and the amount of washing water to be circulated is changed.

  2 and 3 show shower cleaning.

  The shower washing is performed while washing the laundry with the stirring blade 4 while washing the washing water from above the laundry. By washing the laundry exposed on the surface of the washing water with water saving while stirring the shower of washing water, it is possible to perform a good washing without spots.

  FIG. 2 shows shower cleaning when the amount of washing is large. By increasing the operation speed of the circulation pump 45 and increasing the supply amount of washing water, the shower tank 509 (shown in FIG. 37) is moved to the inner tub 3. The spread of the shower 531 spread becomes large. This shower 531 has a large conical shape of a thin film, and washing water is sprayed on the laundry present in the vicinity of the outer periphery of the inner tub 3.

  In the thin-film cone-shaped shower, as described above, the shower flowing out from the shower port 509 is generated by a swirling flow having a fast flow. For this reason, the spread of the shower changes according to the amount of water supplied from the circulation pump 45.

  Therefore, when the operation speed of the circulation pump 45 is decreased to reduce the supply amount of the washing water, the spread of the shower 532 is reduced as shown in FIG. In a small spread by the shower 532, washing water is sprayed on the laundry present in the center of the inner tub 3.

  The large spread shower 531 is when the electric motor 530 is operated at 2800 rpm, and the small spread shower 532 is when the electric motor 530 is operated at 1600 rpm.

  In this shower cleaning, by changing the supply amount of the wash water supplied to the shower port 509, the wash water can be spread over a wide range from the center of the inner tub 3 to the vicinity of the outer periphery of the inner tub 3. Moreover, since it flows from one circular shower port 509, it does not clog lint unlike rain dew.

  However, since it is a thin-film cone-shaped shower, the washing water is not sprayed anywhere other than the outline of the cone.

  Therefore, the shower washing performed during the washing operation is uniformly distributed over the entire laundry present on the inner bottom of the inner tub 3 so that the washing water is uniformly distributed.

  That is, by repeating the washing water spray movement from the center to the outer periphery of the inner tub 3 without resting, the washing water is evenly distributed over the entire laundry present in the inner bottom of the inner tub 3, It can be made uniform.

  FIG. 59 shows an example in which the washing water is uniformly distributed, and the operation pattern of this waveform indicates that the rotational speed of the circulation pump is constantly changing. The number of rotations of the circulation pump is 2800 RPM for the higher one and 1600 RPM for the lower one. At a high rotational speed (2800 RPM), the amount of wash water supplied to the shower port 509 is large. Conversely, at a low rotation speed (1600 RPM), the amount of wash water supplied to the shower port 509 decreases.

  The increase / decrease in the amount of supplied water accompanying the change in the rotational speed at high and low is repeated by switching at intervals of 3 seconds. The switching between the high and low rotational speeds is performed by operation control of the electric motor 530. It is desirable that the time for stopping at a high rotational speed (2800 RPM) and a low rotational speed (1600 RPM) is short, and it is 1 second or less at the longest. By doing so, the increase or decrease in the amount of water supplied to the shower port 509 continues without a break, and the spraying movement of the washing water from the central portion to the outer periphery of the inner tub 3 is repeated without breaks. It is possible to evenly and uniformly distribute the washing water over the entire existing laundry.

  Since operation control of the electric motor 530 is switching between high and low rotation speeds, complicated operation control and control devices are not required, and a simple control device can be obtained.

  Because of the inertia of the electric motor 530, the pump runner, and the resistance of water present in the circulation pump, the change in the rotation speed of the circulation pump does not immediately respond to the switching between the high and low rotation speeds, and the change in the rotation speed of the illustrated gradient is followed. For this reason, it is possible to evenly spray the washing water evenly with a simple control device that switches between high and low rotation speeds.

  In the embodiment shown in FIG. 59, the operation is controlled by repeatedly switching at a high rotation speed (2800 RPM), a low rotation speed (1600 RPM), and an interval of 3 seconds, but the size of the inner tank (diameter size), the circulation pump, The numerical value is determined appropriately depending on the capacity of the motor. The necessary condition is that the amount of water supplied to the shower 509 is continuously increased and decreased in order to evenly spread the washing water over the entire bottom of the inner tub, and the washing from the center of the inner tub to the outer periphery is continued. It is to repeat the water spray movement without break.

  The outline of the control circuit, operation panel, and washing operation of the washing / drying machine will be described with reference to FIGS. 44 to 46.

  The control circuit shown in FIG. 44 includes a main control circuit 600 whose main part is a microcomputer, a load drive control circuit 601, a power supply circuit 602, and an auto-off relay 603, and is supplied with power from a commercial AC power supply 604.

  Power is supplied to the main control circuit 600, the load drive control circuit 601, and the power supply circuit 602 through an auto-off relay 603. The power supply circuit 602 converts alternating current into direct current and supplies it to the main control circuit 600.

  The load drive control circuit 601 includes a water supply valve 7, a soft finish agent valve 605, a detergent melting valve 606, a cooling water valve 607, a drain valve 44, a washing / drying drive motor 10, a clutch 608, a lid lock mechanism 609, and an electric blower 610. Various devices such as the circulation pump 45 and the heater 24 are connected. The load drive control circuit 601 controls energization of various devices under the instruction of the main control circuit 600.

  The main control circuit 600 is connected with various operation switches 612, a water level sensor 47, a temperature sensor 613, a lid opening / closing sensor 614, a nonvolatile storage means 615, a sound generation IC 616, a display unit 617 such as a liquid crystal, and an error notification buzzer 618. The

  The main control circuit 600 communicates information with various operation switches 612, various sensors, and nonvolatile storage means 615, and controls the load drive control circuit 601 and the sound generation IC 616. The main control circuit 600 instructs the display unit 617 to display various types of information including errors and to sound the buzzer 618 when an error occurs.

  Various operation switches 612 are used to input driving information related to washing and drying. The course setting switch 620, the washing switch 621, the rinse switch 622, and the operation switch 611 shown in FIG. 45 and FIG. A dehydration switch 623, a drying switch 624, a start / pause switch 625, a voice switch 626, an energy saving switch 629, a substantially power (on) switch 627, and a power (off) switch 628 are included. An operation panel 611 is disposed on the operation panel 611.

  The start / pause switch 625 also serves as an error release switch that stops error notification described later. When the error release switch is pressed during the error notification, the buzzer 618 for notifying the occurrence of the error and the hella display on the display unit 617 are released.

  A speaker 630 is connected to the sound generation IC 616 operated by the sound switch 626, and information related to the washing and drying operation is provided by sound from the speaker 630.

  The sound generation IC 616 serving as sound generation means includes a sound ROM 640, a D / A converter 641, and an AMP 642. The content of the sound uttered by the speaker 630 is constructed in the sound ROM 640, and the sound generation IC 616 provides the sound under the instruction of the main control circuit 600.

  The operation of the washing operation shown in FIG. 46 proceeds in the order of the washing step 650, the rinsing 1 step 651, the rinsing 2 step 652, and the final dehydration step 653, and the washing operation ends. Thereafter, the process proceeds to a drying operation, which is omitted here.

  The washing process 650 includes a cloth amount measuring step 6501, a washing water supply step 6502, and a washing and stirring step 6503. The rinse 1 process 651 includes a rinse 1 drain step 6510, a rinse 1 dewatering step 6511, a rinse 1 water supply step 6512, and a rinse 1 agitation step 6513.

  In step 6510 of rinsing 1 dehydration, if the amount of imbalance generated by the rotation of the inner tub 3 exceeds a specified value, the process skips to step 6513 of rinsing 1 stirring. Here, dehydration is interrupted, and stirring is changed to water injection.

  The rinse 2 step 652 includes a rinse 2 draining step 6521, a rinse 2 dewatering step 6522, a rinse 2 water supply step 6523, and a rinse 2 stirring step 6524. If the amount of imbalance generated by the rotation of the inner tank 3 exceeds a specified value in the rinse 2 dehydration step 6522, the process skips to the rinse 2 agitation step 6524. Here, dehydration is interrupted, and stirring is changed to water injection.

  The final dewatering step 653 includes a final drainage step 6530 and a final dewatering step 6531. If the amount of imbalance generated by the rotation of the inner tub 3 exceeds a specified value in the final dewatering step 6531, the process skips to the rinse 65 drainage step 6521. Here, the dehydration is interrupted, and the rinsing 2 step 652 and the final dehydration step 653 are performed again.

  The cloth amount measurement in the washing process 650 executed at the beginning of the washing operation will be described with reference to FIGS. 50 to 54.

  Washing is performed with the amount of detergent and the amount of washing water calculated according to the amount of cloth (the amount of laundry) obtained by the cloth amount determination related to the cloth amount measurement. This cloth amount determination is in a dry cloth state in which the laundry is dry. Therefore, if a poultice is mixed, the cloth amount is determined to be larger than the dry cloth amount, and the amount of detergent and washing water is wasted.

  Therefore, the present invention provides a washing / drying machine that can determine the amount of cloth without error even if a compress is present, and that does not waste detergent and washing water.

  FIG. 51 shows the relationship between the measured value of the q-axis current (vector control) of the washing and drying drive motor 10 and the amount of laundry (cloth amount).

  A white circle is a q-axis current integrated value with respect to the amount of laundry including the compress. A black circle is a q-axis current integrated value with respect to the laundry amount of only the dry cloth not including the compress. When the laundry is only a dry cloth, the variation in the q-axis current integrated value is small, whereas when the laundry is mixed with the wet cloth, the variation in the q-axis current integrated value is large.

  FIG. 52 shows the relationship between the fluctuation range and the amount of laundry that are changed by aggregating the measured values shown in FIG. 51 as a comparison between (dry cloth only) and (mixed wet cloth). When the fluctuation range is 20 or less, it is dry cloth, and when it is 20 or more, it is mixed with poultice. Depending on the fluctuation range, it is possible to determine only dry cloth and mixed poultice.

  The amount of washing water to be used is set according to the amount of cloth by the cloth amount determination table (a) shown in FIG. 53 and the cloth amount determination table (b) shown in FIG. The amount of detergent is also set.

  Since the cloth amount determination table (a) is only dry cloth, the water amount corresponding to the determined cloth amount (laundry amount) is set.

  Since the cloth amount determination table (b) is a mixture of compresses, the amount of laundry is reduced from the cloth amount corresponding to the dotted-lined circle to the amount of cloth corresponding to the non-dotted circle. The amount of water corresponding to the amount of cloth subtracted in anticipation of the amount of water contained in the mixed poultice (the amount of laundry dried) is set up. As a result, even in the case of laundry with a mixture of poultices, where the amount of laundry is measured more than the dry cloth alone, the amount of water is set by subtracting the amount measured with water, so wasteful use of washing water and detergent is avoided. Can be suppressed.

  FIG. 50 shows a flow of cloth amount determination.

  In step 661 of the number of measurements following step 660 for starting the cloth amount determination, N times are set, and the drive for washing and drying starts to be driven (step 662). Capture of q-axis current (step 663), stop driving of washing and drying drive motor (step 664), N = N-1 (step 665), N = 0 (step 666), calculation of fluctuation range H (step 667) It changes in the order.

  Then, it is determined whether the fluctuation range H is 20 or less (step 668), and the cloth amount table a is determined (step 669) in the following cases. In the above case, the cloth amount table b is determined (step 670). Based on the respective cloth amount tables, the cloth amount determination process (step 671) is performed, and then the cloth amount determination ends (step 672).

  The standard operation and the energy saving operation (energy saving operation) related to the drying operation will be described with reference to FIGS. 55 to 58, 44, and 45.

  The standard operation of the drying operation is performed as shown in FIG. The energy saving operation is performed as shown in FIG. In the standard operation, a heating and drying operation in which the amount of heat generated by the heater 45 (FIG. 44) is large (strong) is performed, and after the drying is completed, the cooling operation is performed only by blowing. In the energy saving operation, the heating and drying operation with a large (high) heating value of the heater 45 is performed, and when the drying approaches, the heating and switching operation is switched to the weak heating and drying operation with a small (low) heating value of the heater 45. It ends after only cooling operation.

  FIG. 57 shows the relationship between power consumption and operating time in standard operation. FIG. 58 shows the relationship between power consumption and operation time in energy saving operation. The standard operation and the energy saving operation are substantially the same in terms of operation time, but the power saving effect can be expected in the energy saving operation in which the heat generation amount of the heater 45 is reduced to half in the middle of the power consumption.

  In the energy-saving operation, when drying is approaching, even if it is switched to a weak heating drying operation, the residual heat of the fully heated washing dryer is energized to perform drying that is not different from the standard operation, so operation close to standard operation It seems that it can dry in time.

  FIG. 55 shows a flow of energy saving operation.

  In step 681 of the electric blower 610 (ON) / heater 24 (strong) (ON) following the step 680 of starting drying, a heating and drying operation is performed. In the cooling water (ON) (step 682), the cooling water flows down from the downstream 85 (shown in FIG. 5), and the drying air is dehumidified. Initial temperature detection (step 683), temperature detection (step 684), and dryness calculation (step 685) are sequentially performed. When the temperature / dryness becomes equal to or higher than a determination value D1 (step 686) approaching drying, the heater 24 ( (Weak)) (step 687).

  Subsequently, temperature detection (step 688) and dryness calculation (step 689) are sequentially performed, and when the temperature / dryness becomes equal to or higher than the determination value D2 of completion of drying (step 690), switching to the heater 24 (OFF) (step 691). ), Step 692 of electric blower 610 (OFF) / cooling water (OFF) is stepped on, and drying is finished (Step 693).

  The energy saving drying operation is set by the energy saving switch 629 provided on the operation panel 611 shown in FIG. Since the energy saving drying operation and the standard drying operation can be selected by various switches including the energy saving switch 629, it can be appropriately performed according to the amount of laundry and the type of laundry.

  Voice guidance, display, and notification when an error occurs will be described with reference to FIGS. 47 to 49, 44, and 45.

  FIG. 47 shows a flow relating to the operation start process.

  Various operation switches 612 (shown in FIG. 45) are pressed to initialize the operation details including the course of washing and drying and the driving operation (step 700), and the start / pause switch 625 is pressed to start the operation ( Step 701). When the voice switch 626 is pressed and the sound generation permission state is set (step 702) at the start of driving, the voice generation IC 616 is activated, and a voice guide for starting driving is heard from the speaker 630 (FIG. 44) (step). 703), the operation proceeds to the driving operation (step 704).

  In this way, when starting driving, a voice guidance to start driving is provided, so that even a user who is not familiar with it can easily perform the washing operation.

  In step 701, a setting content change is input when waiting for a start failure (step 705). When the sound generation is permitted (step 706), the changed setting content is guided by voice (step 707). ).

  Thus, since the setting content of the washing / drying operation is guided by voice, the content of the washing / drying operation to be started can be confirmed by listening. Even if the surroundings are somewhat dark and the display information on the display unit 617 (shown in FIG. 45) is difficult to see, the setting contents can be accurately grasped by the voice guide.

  FIG. 49 shows a flow relating to error processing in the washing and drying operation.

  In the error process, first, the presence / absence of an error notification state is determined (step 720). In this step 720, when there is no error notification state, an error canceling process (step 721) is performed and the process returns.

  If it is determined in step 720 that the buzzer is not ringing (step 722) despite the presence of an error notification state, the presence / absence of a sound generation permission state is determined (step 723). If it is determined in step 722 that the sound generation permission state exists, the error content and the coping method are notified by voice (step 724), and the process returns to step 721 described above.

  When the buzzer sounds in step 722 and the error release key (step 725) is operated by operating the start / pause switch 625, the buzzer is stopped (step 726) and step 723 (whether or not sound generation is enabled). Proceed to

  When the error release key is not executed in step 725, the voice key (step 727) by operating the voice switch 626 is entered, and the process proceeds to step 726 (buzzer ringing stop). Even if the voice key is not entered in step 727, when a predetermined time elapses and the buzzer ringing time ends (step 728), the process proceeds to step 726 (buzzer ringing stop).

  In addition, when an error occurs even if the sound generation permission state is not set in step 723, the error content and the coping method are always notified by voice in accordance with step 724.

  That is, when an error occurs, the buzzer sounds, and when the start / pause switch 625 is pressed, the buzzer stops sounding, and the error content by voice in the takeover step 724 and the coping method are heard. Even if the start / pause switch 625 is not pressed, when a predetermined time for the buzzer sounding has elapsed, the buzzer sounding stops, and the error contents and the countermeasures by voice are reported.

  In addition, since the error notification buzzer is stopped, it is easy to hear that the error content is notified by voice, and the error content is quickly grasped.

  It should be noted that the buzzer sounding is stopped when reporting the error content by the sound generation means, but the error display shown on the display unit 617 can be continued or stopped.

  The contents of the voice guide when an error occurs are as follows.

(1). Explanation of (1) -1 “Cause” and (1) -2 “State” (2). Explanation of coping method (3). Explanation that operation resumes without turning off the power
* When operation can be resumed by taking measures (4). After that, explanation of the process (can / can't continue)
A specific example of the voice guide based on the above contents is shown below.

The "
In addition to ringing by the buzzer and coping with the display unit in response to such an error occurrence, the content of the error and the coping method are announced by voice so that the error can be quickly resolved. In particular, even if the user forgets to press the voice switch 626 to ask for voice guidance, the voice notification to deal with the occurrence of the error is notified in addition to the buzzer sounding and the notification on the display section, so that the convenience of the washing and drying machine is further improved. .

  If it is determined in step 723 that the sound generation permission state is NO, no voice guidance is executed. This is a case where the voice guidance is set to be disabled so that voice guidance is not performed. When the voice guidance is disabled, voice guidance is not performed even if the start / pause switch 625 or the voice switch 626 is turned on during the buzzer sounding / error notification.

  FIG. 48 is a flow of operation start processing including error information reading.

  In this flow, since the latter half of Step 700 is the same as the flow related to the operation start process described in FIG. 47, the same reference numerals are attached and the description is omitted.

  First, error information is read from the nonvolatile storage means 615 (shown in FIG. 44) (step 730). Subsequently, the presence / absence of an error is determined (step 731). If there is no error, the process proceeds to step 700.

  If there is an error in step 731, it is determined whether there is a sound generation permission state (step 732). If there is a sound generation permission state in step 732, an error content by voice and a coping method are notified (step 733). When the error release key reception (step 734) is performed, the error display and the sound generation are stopped (step 735), and the process proceeds to step 700.

  When the error release key reception (step 734) is not performed, the announcement of the error content by voice and the coping method is repeated. If this announcement is repeated several times, it is possible to proceed to step 700.

  If it is determined in step 732 that the pronunciation permission state is not present, an error is displayed on the display unit (736). Also, buzzer sounds are added as necessary. Then, the process proceeds to Step 734.
