Description

The present invention relates to a washing machine.

Generally, in a vertical washing / drying machine, a rotary wing is provided at the bottom of an inner tub that houses clothes, and the rotary wing is rotated in the forward and reverse directions with water stored in the inner tub and the outer tub that rotationally supports the rotary wing. Let it wash. Then, in the drying step after the inner tank is rotated at high speed to complete the dehydration, the warm air heated by the heater is blown to the clothes by the blower fan. Moisture contained in clothes evaporates due to warm air, air containing moisture is guided to a circulation path, and the moisture is removed by a dehumidifying mechanism provided in this circulation path.

For example, in order to effectively dry clothes, in Patent Document 1, high-pressure warm air is blown from a blowing nozzle protruding from the center of the top surface of the dehydration tank to the center of the pulsator while stirring with the pulsator. There is. Further, in Patent Document 2, an outlet whose flow path area gradually decreases is provided diagonally toward the center side of the washing tub at the upper part on the outer peripheral side of the washing tub, and the tip of the outlet is projected from the fixed surface of the outlet.

However, in the washer / dryer described in Patent Document 1, when the pulsator is rotated, the clothes move to the outer peripheral side of the inner tub. For this reason, the warm air blown to the center of the inner tank is less likely to hit the clothes directly, the amount of air blown to the clothes is reduced, the wind speed hitting the clothes is slow, the force to spread the clothes is reduced, and the clothes are blown from the clothes. Evaporation of water is suppressed, wrinkles are generated, and drying efficiency is reduced.

Further, in Patent Document 1, warm air is blown from the center of the top surface of the upper part of the dehydration tank toward the center of the pulsator. In Patent Document 2, the outlet is directed toward the center of the inner tank. Therefore, when the wind speed is relatively high, the wind is blown to the center of the inner tank and cannot hit the clothes.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a washing machine having good drying efficiency and finish.

The present invention relates to a housing, an outer tank housed in the housing, an inner tank housed in the outer tank, a blower house housed in the housing to generate warm air, and a blower unit. It is provided with an inflow port into which warm air flows and a throttle portion provided on the outer peripheral side inside the inner tank to gradually reduce the cross-sectional area of the flow path from the inlet.

The microcomputer 40 is activated when the power switch 5 is pressed and the power is turned on, and executes a basic washing and drying control processing program as shown in FIGS. 6 and 7. The control flow will be described below.

<< Step S101 >>
As shown in FIG. 6, the state of the washer / dryer is confirmed and the initial setting is performed.

<< Step S102 >>
The display 7 of the operation panel 8 is lit and displayed, and the washing course is set according to the instruction input from the operation button switch 6. If there is no instruction input, the standard washing course or the previous washing course is automatically set.

<< Step S103 >>
The process is branched by monitoring the instruction input from the start switch 6a in the operation button switch 6 of the operation panel 8.

<< Step S104 >>
Execute the detergent amount detection process. This detergent amount detection is based on the amount of rotational load acting on the rotary blade 11 when the rotary blade 11 is rotated in one direction with the inner tank 9 stationary in the dry cloth state before the washing water is supplied. The washing / dehydrating drive motor 13 and the clutch mechanism 12 in the drive mechanism are controlled so as to detect the cloth amount of the clothes 56, and an appropriate amount of detergent (detergent amount) is obtained based on the detected cloth amount.

The amount of detergent is determined by referring to a preset control table of the amount of cloth and the amount of detergent. Specifically, in the configuration in which the inverter-driven motor is used as the washing / dehydrating drive motor 13, the amount of cloth is detected by detecting the reached rotation speed when power is supplied for a predetermined time so as to rotate the washing / dehydrating drive motor 13. conduct. In the configuration in which the condenser phase-dividing single-phase induction motor is used as the washing / dehydrating drive motor 13, the inertial rotation / deceleration characteristic after the power is cut off while the washing / dehydrating drive motor 13 is supplied with power to increase it to the saturated rotation speed is detected. Do by. Then, the preferable amount of detergent is obtained by referring to the control table of the amount of cloth and the amount of detergent set in advance.

The amount of washing water is set so that when the amount of cloth is within a predetermined range (appropriate amount), the water level does not exceed the rotary blade 11 and is collected at the bottom of the outer tub 10. In addition, the washing time is obtained and set based on this detection result (cloth amount). When the cloth amount detection is not performed, a standard washing time is set.

<< Step S105 >>
The obtained amount of detergent is displayed on the display 25 of the operation panel 8.

<< Step S106 >>
The detergent water supply solenoid valve is opened, and detergent water is supplied to the detergent input chamber of the detergent / finishing agent container 28. The user operates to close the outer lid 3 after charging the displayed amount of powder detergent or liquid detergent into the detergent charging chamber of the detergent / finishing agent container 28. The powder detergent or liquid detergent charged into the detergent charging chamber in which the detergent water is flowing passes through the detergent / finishing agent inlet 28a together with the detergent water and falls to the bottom of the outer tank 10.

<< Step S107 >>
When the detergent is dissolved and the water is supplied to the water level, the water supply is stopped. The detergent-dissolving water level is an amount of water sufficient to stir the water supplied at the bottom of the inner tank 9 and the detergent when the inner tank 9 is rotated in the subsequent detergent-dissolving step (step S108), and the water surface. Is set to be lower than the height of the lower surface of the rotary blade 11 (the clothing 56 does not get wet before the detergent is dissolved).

<< Step S108 >>
By integrally rotating the inner tank 9 and the rotary blade 11 in one direction at a slow speed, the detergent-dissolved water charged into the bottom of the outer tank 10 and the powder detergent or liquid detergent are agitated at the bottom surface of the inner tank 9. Perform a detergent dissolve, which produces a high detergent concentration of wash water.

≪Step S109≫
Perform a pre-wash. In this pre-washing, stirring is intermittently performed to rotate the rotary blade 11 forward and reverse while the inner tank 9 is stationary, and the circulation pump 16 is operated during the forward and reverse rotation of the rotary blade 11 to operate the outer tank 10. The detergent water at the bottom is poured from the nozzle 34 onto the clothing 56. At this time, since the high-concentration detergent water is sprayed on the clothes 56, the detergent permeates the clothes 56 evenly due to the penetrating action of the detergent. The high-concentration detergent water that has permeated the clothes 56 has a high oil-dissolving ability, dissolves oil-and-fat stains such as sebum stains, and has a very large effect of raising the stains from the clothes 56, so that high detergency can be obtained. Next, during the stop period of the rotary blade 11 and the circulation pump 16, the detergent water supply solenoid valve and the washing water supply solenoid valve are opened while referring to the detection signal of the water level sensor 21, and water is supplied so that the water level does not exceed the set water level. .. By repeating this operation a plurality of times, the clothes 56 are soaked in washing water and dispersed on the rotor blade 11.

<< Step S110 >>
Perform a main wash. In this main washing, first, the cloth amount is detected by the same method as described above, and the set washing time is corrected and set. After that, the circulation pump 16 is operated while rotating the rotary blade 11 in the forward and reverse directions with the inner tank 9 stationary, and the washing water collected at the bottom of the outer tank 10 is dropped from the nozzle 34 onto the clothing 56. And the cloth loosening stirring in which the rotary blade 11 is rotated in the forward and reverse directions in a state where the operation of the circulation pump 16 is stopped and the circulation of the washing water is stopped is repeated. Due to the forward and reverse rotation of the rotary blade 11, the clothing 56 is replaced in the circumferential direction and the radial direction in the inner tank 9, and is washed evenly. Finally, with the operation of the circulation pump 16 stopped and the circulation of the washing water stopped, uniform stirring for rotating the rotary blades 11 in the forward and reverse directions is executed to end the main washing time.

<< Step S111 >>
As shown in FIG. 7, the first pool rinse is performed. In this reservoir rinsing, first, the drain valve 15 is opened to drain the washing water accumulated at the bottom of the outer tank 10, and then the inner tank 9 and the rotary blade 11 are integrally rotated in one direction to the clothes 56. Centrifuge the contained wash water. The rotation speeds of the inner tank 9 and the rotary blade 11 at the time of dehydration of the washing water are set in the same manner as the rotation speed (about 1000 r / min) in the final dehydration described later, and the dehydration operation is performed so as to realize a high dehydration rate.

After that, while closing the drain valve 15 and rotating the inner tank 9 and the rotor 11 at a slow speed in one direction, the washing water supply solenoid valve is opened and tap water is sprinkled from the sprinkler port to the clothes 56 on the rotor 11. Water is supplied as if it were falling.

Next, with the rotation of the inner tank 9 and the rotary blade 11 stopped, rinse water is supplied so that the water level at the bottom of the outer tank 10 does not exceed the set water level.

Next, as in the case of push-washing stirring in the main washing, the circulation pump 16 is operated while the rotary blade 11 is rotated in the forward and reverse directions while the inner tank 9 is stationary, and the rinse water accumulated in the bottom of the outer tank 10 is discharged. Rinse water circulation stirring rinsing is performed, which is circulated so as to fall from the nozzle 34 onto the clothing 56 on the rotor 11.

Next, with the rotation of the rotary blade 11 and the operation of the circulation pump 16 stopped, water is supplied so that the water level does not exceed the set water level while detecting the water level of the rinse water accumulated at the bottom of the outer tank 10.

Next, while the rotary blade 11 is rotated forward and reverse while the inner tank 9 is stationary, the circulation pump 16 is operated to remove the rinse water collected at the bottom of the outer tank 10 from the nozzle 34 to the clothing 56 on the rotary blade 11. Perform a rinsing water circulation stirring rinse that circulates so that it falls on the water. As in the case of washing, the clothes 56 in the inner tank 9 are switched in the circumferential direction and the radial direction, so that the rinse water is evenly applied to the clothes 56, and the detergent content is diluted.

After that, with the circulation pump 16 stopped and the circulation of the rinse water stopped, uniform stirring is performed to continue the forward and reverse rotation of the rotary blade 11.

<< Step S112 >>
Perform the second pool rinse. In this second pool rinsing, the flexible finishing agent water supply solenoid valve is opened to supply water to the flexible finishing agent charging chamber in the detergent / finishing agent container 28, so that the flexible finishing agent in the flexible finishing agent charging chamber is supplied to the outer tank 10. Add control to introduce to the bottom of. Other operations are performed in the same manner as in the first pool rinsing.

<< Step S113 >>
Perform the final dehydration process. In the final dehydration, with the drain valve 15 open, the inner tank 9 and the rotary blade 11 are integrated, and the drive mechanism is operated so as to rotate at a high speed of about 1000 r / min in one direction. The clothes 56 in the tank 9 are centrifugally dehydrated. The operation time of this final dehydration is set to a time at which a desired dehydration rate can be obtained.

<< Step S114 >>
Check if the washing / drying course is set and branch the process. If the washing / drying course is not selected, washing is completed and this control flow ends. On the other hand, if the washing / drying course is selected, the drying process is started and the following steps are performed.

≪Step S200≫
In the drying step, the inner tank 9 is rotated at high speed in order to further dehydrate the clothes 56. If sufficient dehydration has been performed in the previous washing step, this step can be omitted.

<< Step S201 >>
This is a process for performing step S200 for a predetermined time, and the dehydration step is executed until a predetermined predetermined time elapses. This step can also be omitted if sufficient dehydration has been performed in the previous washing step.

<< Step S202 >>
The warm air 51 blown from the blower fan 19 and heated by the heater 20 is blown out from the air passage 65 into the inner tank 9 through the blowing portion 54. The air passage 65 is directed toward the bottom of the outer circumference, and high-speed warm air 51 is blown to the bottom of the outer circumference.

<< Step S203 >>
By rotating the inner tub 9 (washing tub) and the rotary wing 11 at a slow speed integrally, or by rotating the rotary wing 11 in the forward and reverse directions while the inner tub 9 is stationary, the entire clothes 56 are heated while stirring. Let it dry. Further, since the clothing 56 moves to the outer peripheral side of the inner tank 9 when the rotary blade 11 is rotated, when the warm air 51 is blown to the outer peripheral bottom portion, it is easy to directly blow the wind to the clothing 56. By directly applying the high-speed warm air 51 to the clothes 56, the evaporation of water from the clothes 56 is promoted and the drying efficiency is improved, and the clothes 56 are further spread and wrinkles generated during drying are reduced. Further, when the rotary blade 11 is rotated, the clothing 56 is lifted by the gently inclined surface 11h of the rotary blade 11. As the clothes 56 are lifted and the distance between the blowout portion 54 and the clothes 56 becomes closer, the wind speed of the warm air 51 blown to the clothes 56 increases, so that the clothes 56 are further expanded and wrinkles generated during drying are generated. Reduce.

<< Step S204 >>
It is executed while monitoring the temperature of the hot air by the temperature sensor 26, and when the rate of temperature change reaches a predetermined value, it is determined that the drying is completed. If the clothes 56 are not dry, the inner tank 9 or the rotary blade 11 in step S203 is rotated to perform the determination in step S204 again.

≪Step S205≫
After turning off the heater 20, the blower fan 19 is further turned off, the rotation of the inner tank 9 and the rotary blade 11 is stopped, and the drying process is completed.

In the washer-dryer provided with such a configuration, the characteristic configuration of the present invention will be described next.

The throttle portion 63 has an inclination in which the cross-sectional area of the flow path (horizontal slice cross-sectional area in the horizontal direction) gradually decreases downward, and the throttle inlet 62 is formed at the upper end and the throttle outlet 64 is formed at the lower end. .. The throttle inlet 62 is formed continuously with the inflow portion 61. Further, the throttle portion 63 coincides with the radial center of the flow path cross-sectional area (round-cut cross-sectional area) of the throttle inlet 62 and the radial center of the flow path cross-sectional area (round-cut cross-sectional area) of the throttle outlet 64.

Further, the throttle portion 63 has an inclined surface 63a (inclined portion on the center side) formed on the center side (front side) of the inner tank 9 and an inclined surface 63b formed on the outer peripheral side (rear surface side) of the inner tank 9. It has (inclined part on the outer peripheral side). Further, the inclined surfaces 63a and 63b both have the same inclination angle with respect to the axial direction (vertical direction).

The air passage 65 is continuous with the throttle outlet 64, which is the outlet of the throttle portion 63, and the accelerated warm air 51 is made to have straightness and is blown into the inner tank 9 (see FIG. 2). Further, the air passage 65 has a flow path cross-sectional area (round-cut cross-sectional area) at the throttle outlet 64 (air passage inlet) and a flow path cross-sectional area at the air passage outlet 66 where warm air blows into the inner tank 9 (round-cut cross-sectional area). Area) is the same.

Further, the air passage 65 is arranged so that the outer peripheral surface of the air passage 65 enters to a position facing the inner wall surface 9c1 of the fluid balancer 9c. In other words, the air passage outlet 66 is located vertically below the upper surface 9c2 of the fluid balancer 9c.

Further, the blowout portion 54 is integrally formed with the tank cover 31 by resin molding. As a result, the number of parts can be suppressed, the gap generated in the case of a separate body can be eliminated, and the air leakage generated from the gap can be suppressed. In addition, in order to suppress deformation due to the temperature of the warm air flowing through the blowout portion 54, it is desirable that the material is made of a material having a heat resistance of 80 degrees or higher (for example, a resin containing glass fiber).

During the drying process of the washer / dryer 100, the warm air generated by the blower fan 19 flows from the inflow port 60 into the inflow section 61, and is sent to the downstream air passage 65 while increasing the speed by the throttle section 63. Blow into the tank 9. At this time, the warm air 51 is blown from the tip (tip) of the air passage 65 toward the bottom in the vertical direction.

At this time, by directly blowing the high-speed warm air 51 onto the clothes 56 (see FIG. 2), a high force to spread the clothes 56 can be obtained. Further, since the evaporation of water from the clothes 56 is promoted, wrinkles generated during drying are reduced and the drying efficiency is improved.

Further, during the drying process, the clothes 56 tend to collect at the outer peripheral bottom portion of the inner tank 9 due to the rotation of the rotary blade 11 (see FIG. 2), so that the warm air 51 is blown toward the outer peripheral bottom portion. Further, in order to suppress the decrease in the wind speed of the warm air 51, it is preferable to blow the wind (warm air 51) in a direction not to hit the wall surface of the inner tank 9 before hitting the clothes 56. Further, it is desirable to blow out warm air 51 in the vicinity of the vertical portion of the blowing portion 54 so that the clothes 56 can be hit by a short distance.

Therefore, the blowout portion 54 is provided above the outer peripheral side where the clothes 56 are likely to collect in the vertical direction. In FIG. 9, the broken line ◯ indicates the position of a point substantially vertically below the outlet (throttle outlet 64) of the throttle portion 63 at the bottom of the inner tank 9. The position where the warm air 51 is blown to the bottom of the inner tank 9 is not limited to the position (one point) indicated by the broken line ◯, and as shown in the shaded area in FIG. 9, the throttle outlet. The inside (inside) of the quadrant drawn at ± 45 degrees in the circumferential direction with respect to the broken line 〇 mark substantially vertically below 64, and the outer circumference side from half (middle of the radial direction R) with respect to the radial direction R. It is desirable to blow wind on the warm air blowing area 70. As described above, the directions of the throttle outlet 64 and the air passage 65 are preferably directed to the warm air blowing region 70.

Further, the wind blown out to the inner tank 9 entrains the air in the tank and diffuses while lowering the central wind speed. In order to spread the clothes 56 at the bottom of the inner tank 9 by the wind, it is desirable to suppress diffusion, maintain the central wind speed, and allow the warm air 51 to reach the bottom of the inner tank 9 as high as possible. Therefore, in the first embodiment, the air passage 65 is provided on the downstream side of the throttle portion 63, and the high-speed warm air 51 is guided to the bottom of the inner tank 9.

FIG. 10 shows the temperature when the air passage 65 is not provided at the tip of the throttle portion 63 (left figure in FIG. 10) and when the air passage 65 is provided at the tip of the throttle portion 63 (right figure in FIG. 10). It is a schematic diagram which shows the way of diffusion of a wind 51. The shape of the diaphragm portion 63 in the left figure and the right figure in FIG. 10 is the same. Further, the case of the left figure of FIG. 10 is also included in the embodiment of the present invention.

As shown in the left figure of FIG. 10, when the air passage 65 is not provided, when the wind is collected by the throttle portion 63, the wind flows in the inclined direction at the peripheral portion (the side close to the inclined surface). Therefore, when the wind blows out from the throttle outlet 64 (the outlet of the throttle portion 63), the wind blows out from the throttle outlet 64 with a relatively wide spread due to the component in the inclination direction. On the other hand, as shown in the right figure of FIG. 10, when the air passage 65 is provided, the wind collected by the throttle portion 63 is rectified in one direction by the air passage 65, so that the air passage is relatively straight. Is blown out from the air passage outlet 66 and is sprayed on the clothing 56 at the bottom of the inner tank 9.

As described above, the throttle portion 63 and the air passage 65 are provided on the outer peripheral side in the radial direction of the tank cover 31 so that the cross-sectional area of the flow path gradually decreases. As a result, the wind is blown to the warm air blowing region 70 (see FIG. 9) vertically below the throttle outlet 64 and on the outer peripheral side of the inner tank 9, so that the clothes brought to the outer peripheral side of the inner tank 9 by the rotary blade 11. High-speed warm air 51 can be effectively blown directly onto the 56. As a result, the clothes 56 are effectively spread, the evaporation of water from the clothes 56 is promoted, wrinkles generated during drying are reduced, and the drying efficiency is improved. By improving the drying efficiency, it is possible to reduce the power consumption during drying.

In the first embodiment, the flow path area of the air passage 65 is substantially constant in order to suppress the pressure loss, but the wind speed can be further increased by narrowing the flow path area of the air passage 65 as well. In that case, in order to make the wind flow at the air passage outlet 66 uniform, it is desirable to reduce the flow within a range smaller than the contraction ratio of the throttle portion 63. That is, (throttle outlet 64 / air passage outlet 66) <(throttle inlet 62 / throttle outlet 64) may be used by using the flow path cross-sectional areas of the throttle inlet 62, the throttle outlet 64, and the air passage outlet 66.

Further, since the warm air 51 blown out from the air passage outlet 66 is not applied to the fluid balancer 9c, the air passage outlet 66 is provided at a height position lower than the upper surface 9c2 of the fluid balancer 9c.

Further, if the swelling clothes 56 are entangled in the air passage 65 during the drying process, the clothes 56 are wrinkled, which leads to deterioration of the finish. Therefore, it is desirable that the air passage outlet 66 is provided above the lower surface 31d1 (see the broken line in FIG. 8) of the tank cover 31. As a result, damage and wear of the air passage 65 due to contact between the clothing 56 and the air passage 65 can be suppressed.

Further, in the first embodiment, the tank cover 31 is configured to have a relatively thick structure by stacking two sheets of the tank cover upper plate 31c (see FIG. 8) and the tank cover lower plate 31d (see FIG. 8). ing. As a result, the air passage outlet 66 can be easily provided on the lower surface of the tank cover 31, that is, above the lower surface 31d1 of the tank cover lower plate 31d.

Further, in the first embodiment, in order to prevent clothes 56 from entering between the tub cover 31 and the fluid balancer 9c during the washing (washing) step or the drying step, that is, the lower surface of the tub cover lower plate 31d. 31d1 is provided below the upper surface 9c2 of the fluid balancer 9c.

The air passage 65 is arranged inside the opening of the inner tank 9 and the fluid balancer 9c (inside the inner wall surface 9c1), but a part of the inflow port 60 is outside the opening (inside the opening by the throttle portion 63). It is arranged on the inner wall surface (outside the radial direction of 9c1) (see the broken line in FIG. 8). As described above, it is desirable to provide the inflow port 60 on the back side of the housing (outer frame) 1 as much as possible. As a result, the bellows tube 29b located upstream of the inflow port 60 can be arranged on the back side of the housing (outer frame) 1 as much as possible, so that the clothes inlet 31a provided on the front side can be widely secured and more smoothly. The clothes 56 can be taken in and out.

The inclination angle α of the diaphragm portion 63 with respect to the axial direction may not be substantially constant. For example, when the inclination angle is set so that the slope becomes steeper (the slope becomes parallel to the axial direction) as it goes to the downstream side, the space S outside the throttle portion 63 can be widened, so that the inflow port 60 Can be moved closer to the back side of the housing (outer frame) 1.

As described above, the washer / dryer 100 of the first embodiment is provided in the housing 1, the outer tub 10 housed in the housing 1, the inner tub 9 housed in the outer tub 10, and the housing 1. Blowers (blower fan 19, heater 20, drying duct 22, dehumidifying mechanism 22a) that are housed and generate hot air 51, inflow port 60 into which warm air 51 from the blower flows, and the outer peripheral side of the inner tank 9. It is provided with a throttle portion 63 that gradually reduces the cross-sectional area of the flow path from the inflow port 60. The aperture outlet 64 is the bottom of the inner tank 9, inside a quadrant drawn at ± about 45 degrees in the circumferential direction with respect to a point substantially vertically below the aperture outlet 64, and from the middle with respect to the radial direction R. It is oriented toward the outer peripheral area (see FIG. 9). According to this, the warm air 51 can be blown from the squeezing portion 63 onto the clothes 56 at a high speed, so that the drying efficiency and the finish are improved.

Further, in the first embodiment, an air passage 65 for blowing out warm air 51 is provided inside the inner tank 9 on the downstream side of the throttle outlet 64 (see FIG. 8). According to this, it is possible to suppress the diffusion of the warm air 51, maintain the central wind speed, and allow the warm air 51 to reach the bottom of the inner tank 9 as high as possible.

Further, the first embodiment has a tank cover 31 that covers the upper surface of the outer tank 10, and the tank cover 31 has a throttle portion 63 (see FIG. 8). According to this, the number of parts can be reduced.

Further, in the first embodiment, the throttle outlet 64 is located inside the opening of the inner tank 9 (inner wall surface 9c1 of the fluid balancer 9c) in the radial direction, and at least a part of the inflow port 60 is the opening (inside). It is located on the outer peripheral side of the wall surface 9c1) (see FIG. 8). According to this, since the position of the blowout portion 54 can be made closer to the back side, the opening of the clothes inlet 31a can be secured wider, and the clothes 56 can be easily taken in and out.

Further, in the first embodiment, the flow path cross-sectional areas of the throttle outlet 64 and the air passage 65 are the same. According to this, it is possible to suppress the occurrence of pressure loss by narrowing the air passage 65.

Further, in the first embodiment, the tank cover 31 is configured by combining the tank cover upper plate 31c and the tank cover lower plate 31d, and the tank cover upper plate 31c has a throttle portion 63 and an air passage 65 (FIG. FIG. 8). The tank cover upper plate 31c constitutes the shape of the upper surface side of the tank cover 31. The tank cover lower plate 31 constitutes the shape of the lower surface side of the tank cover 31. According to this, if the throttle portion 63 and the air passage 65 are provided on the tank cover lower plate 31d, a connection boundary is generated between the tank cover upper plate 31c and the tank cover upper plate 31c. It does not occur and the occurrence of air leakage can be prevented.

(Second Embodiment)
FIG. 11 is a vertical sectional view showing the washer / dryer of the second embodiment. FIG. 12 is an enlarged cross-sectional view of the outlet according to the second embodiment.
As shown in FIG. 11, the washer / dryer 100A of the second embodiment includes a blowout portion 54A in place of the blowout portion 54 of the first embodiment. Since the other configurations are the same as those in the first embodiment, the same reference numerals are given and duplicated description will be omitted.

As shown in FIG. 12, the outlet portion 54A includes an inflow port 60, a throttle portion 63A, and an air passage 65. The diaphragm portion 63A has a substantially conical shape that narrows from the upper side to the lower side in the vertical direction (axial direction).

Further, the throttle portion 63A has an inclined surface 63c formed on the outer peripheral side (back surface side) of the inner tank 9. Further, in the throttle portion 63A, the surface 63d formed on the center side (front side) of the inner tank 9 is formed by a surface parallel to the axial direction (vertical direction). As described above, the inclined surface 63c and the surface 63d have different inclination angles.

Further, when the front side of the housing (outer frame) 1 is tilted (the angle with respect to the vertical direction (axial direction) is 0 degrees), the back side is tilted (the angle β with respect to the vertical direction (axial direction), the inclined surface 63c). It is configured to be steeper.

Further, the cross-sectional center O1 of the throttle outlet 64 is configured to be located on the front surface side of the housing (outer frame) 1 from the cross-sectional center O2 of the inflow port 60. With such a configuration, when the wind flowing through the inflow port 60 is biased toward the front side of the housing (outer frame) 1 (see the solid line arrow in FIG. 11), the pressure loss is relatively suppressed. , The throttle portion 63A makes it possible to throttle the wind.

That is, in the second embodiment, the blower fan 19 is provided in the upper part on the back side of the housing (outer frame) 1 behind the blowout portion 54A. As shown by the solid arrow in FIG. 11, after exiting the blower fan 19, the wind is sent to the upper part of the bellows tube 29b while flowing from the back side to the front side, and is bent substantially vertically to pass through the bellows tube 29b. It is guided to the inlet 60. By bending the fluid in this way, the fluid is likely to be collected outward from the center side of the bending. Flows. That is, a flow that is fast on the front side and slow on the back side reaches the inflow port 60 and the throttle portion 63A.

By the way, in order to suppress the pressure loss and throttle the wind, it is desirable to arrange the throttle outlet 64 on the front side where the fast flow gathers, widen the inclined surface of the throttle portion 63A on the back side, and compress the slow flow. .. Therefore, the structure is such that the cross-sectional center O1 of the throttle outlet 64 is closer to the front side with respect to the cross-sectional center O2 of the inflow port 60. Specifically, the front side end portion 60a of the inflow port 60 and the front side end portion 64a of the throttle outlet 64 are aligned in the vertical direction. As a result, it is possible to suppress the contraction of the front side where the fast flow gathers and further suppress the pressure loss. As a result, the warm air 51 that has been squeezed while suppressing the pressure loss of the wind is blown to the warm air blowing region 70 (see FIG. 9) at the bottom of the inner tank 9 by the air passage 65.

Therefore, it is possible to efficiently blow the high-speed warm air 51 to the outer peripheral bottom portion of the inner tank 9 where the clothes 56 tend to collect. As a result, the wind speed directly blown on the clothes 56 increases, the force for spreading the clothes increases, and the evaporation of water from the clothes 56 is promoted, so that wrinkles generated during drying are reduced and the drying efficiency is improved. do.

Further, in the blowout portion 54A shown in FIG. 12, the inflow port 60 can be arranged on the back side from the position of the first embodiment while the air passage 65 is housed inside the inner tank 9 and the fluid balancer 9c. Yes (see the dashed line in FIG. 8 and the dashed line in FIG. 12). As a result, the clothes input port 31a is secured wider, and the clothes 56 can be smoothly taken in and out.

Further, in the second embodiment, the structure in which the throttle outlet 64 fits in the circumference of the inflow port 60 is described as an example, but it is not necessary to make the structure in which the throttle outlet 64 fits in the circumference of the inlet 60. .. For example, when the throttle outlet 64 is arranged so as to come out to the front side with respect to the inflow port 60, the inflow port 60 can be further provided on the back side, the clothes inlet 31a is widened, and the clothes 56 can be further taken in and out. It will be smooth.

In the second embodiment, in the inflow port 60, the throttle outlet 64 is throttled so as to be closer to the front side than the inflow port 60 in order to effectively throttle the wind flowing unevenly toward the front side of the housing (outer frame) 1. The slope is provided. However, it may be provided according to the direction of the drift at the inlet 60. For example, when the wind is biased to the back side, the throttle outlet 64 may be arranged so as to be on the back side of the inlet 60.

(Third Embodiment)
FIG. 13 is an enlarged cross-sectional view of the tank cover provided with the outlet according to the third embodiment. The overlapping part is omitted for the configuration common to the first embodiment.
As shown in FIG. 13, the washer / dryer of the third embodiment includes a tub cover 31A instead of the tub cover 31. The tank cover 31A is configured by combining a tank cover upper plate 31c and a tank cover lower plate 31e. The tank cover lower plate 31e is configured such that the lower surface 31e1 of the tank cover lower plate 31e is continuous with the end (lower end, tip) 65a of the air passage 65. In other words, the lower surface 31e1 of the tank cover lower plate 31e is flush with the end 65a (end surface) of the air passage 65, and the end 65a is configured so as not to protrude downward from the lower surface 31e1 of the tank cover lower plate 31e. There is.

By the way, when the clothes 56 are contained in a relatively large amount with respect to the capacity of the inner tank 9, contact between the tank cover 31 (see FIG. 8) and the clothes 56 is likely to occur. During the drying process, when the clothes 56 rolled up by the wind slide on the lower surface of the tank cover 31 and come into contact with the air passage 65, the twist of the clothes 56 caused by the slipping causes deterioration of the finish. By providing the gently sloping surface 31e2 around the end portion 65a of the air passage 65, the entanglement of the clothing 56 is suppressed and the finish is improved. Further, it is possible to prevent the throttle portion 63 and the air passage 65 from being damaged or worn due to contact.

Even if there is no inclined surface 31e2 around the air passage 65, the lower surface 31e1 of the tank cover lower plate 31e is on the same surface as the end portion 65a of the air passage 65 on a horizontal plane, and the end portion 65a protrudes from the lower surface 31e1. If there is no structure, the same effect can be expected.

(Fourth Embodiment)
FIG. 14 is a configuration diagram of the washer / dryer of the fourth embodiment.
In the first embodiment, the case where the throttle outlet 64 and the air passage 65 are directed to the substantially vertical direction where the clothing 56 is applied at the shortest distance and the warm air 51 is blown is described, but the direction in which the warm air 51 is blown is It is not limited to the vertical direction.

For example, as shown in FIG. 14, due to the rotational operation of the rotary blade 11 at the bottom of the inner tank 9, the clothing 56 moves to the outer peripheral portion and at the same time moves in the circumferential direction. Therefore, warm air 51 is blown against the clothing 56 moving in the circumferential direction so as to be a headwind (see the white arrow and the solid line arrow in FIG. 14). As a result, the wind blown to the clothes 56 becomes relatively fast, a higher force for spreading the clothes 56 can be obtained, the drying efficiency of the clothes 56 is improved, and the occurrence of wrinkles on the clothes 56 is reduced.

Further, by blowing the wind in a direction substantially perpendicular to the inclined surface 11h of the rotary blade 11, the force for spreading the clothes 56 on the inclined surface 11h can be further obtained, so that the drying efficiency of the clothes 56 can be improved. It is improved and the occurrence of wrinkles on the garment 56 is reduced.

(Fifth Embodiment)
FIG. 15 is a block diagram of the washer / dryer of the fifth embodiment.
In the second embodiment shown in FIGS. 11 and 12, in the inflow port 60, the throttle outlet 64 is set from the inflow port 60 in order to effectively throttle the wind that flows unevenly toward the front surface side of the housing (outer frame) 1. The diaphragm portion 63 is inclined so as to be located on the front surface side. However, depending on the arrangement of the blower fan 19, the wind flows unevenly toward the back side. In that case, it is desirable to provide an inclination so that the throttle outlet 64 is arranged on the back side of the inlet 60.

For example, as shown in FIG. 15, when the blower fan 19A is relatively small and the outlet 19a of the blower fan 19A is arranged on the front side of the blowout portion 54, the wind flows from the front side to the back side and the bellows tube 29b. Sent to the top of. Therefore, the wind flows unevenly in the bellows tube 29b from the center of the shaft toward the back surface side of the housing (outer frame) 1. Therefore, it is preferable to provide an inclination so that the throttle outlet 64 is arranged on the back side of the inlet 60.

The present invention is not limited to the above-described embodiment, and includes various modifications. For example, the shapes of the inflow portion 61, the throttle portions 63, 63A, and the air passage 65 of the first embodiment are not limited to a substantially cylindrical shape and a substantially conical shape, and the blowout portions 54, 54A are integrated with the tank covers 31, 31A. It is not limited to those configured in.

Further, when the warm air 51 is blown to the warm air blowing region 70 at a relatively high speed, the same effect can be obtained even if the air passage 65 is omitted as shown in the left figure of FIG. ..

Further, in the washer-dryers 100 and 100A of the present embodiment, the heater 20 (see FIGS. 2 and 11) has been described as a heat source, but the same effect can be obtained even if the heat source is a heat pump.

Further, in the present embodiment, the washing / drying machine provided with the tub covers 31 and 31A has been described as an example, but the present embodiment can also be applied to a washing machine having a drying function not provided with the tub covers 31 and 31A.
