[Ventilation route]
First, the air flow during preheating of the laundry before the start of washing by the pulsating blade 11 will be described with reference to the drawings. 4 to 6, 9, and 10, white arrows, white dashed arrows, and dashed arrows schematically represent the flow of air that heats the laundry.

  9 and 10, the air in the inner tub 9 is removed from the through-hole 158 of the outer tub cover 14 in the upper part of the washing tub by the drying fan 64 of the drying unit 60, as indicated by white arrows and white dashed arrows. The air is taken into the circulation air passage 18 inside the tank cover 14 (see FIG. 9) and reaches the air discharge port 145 through the circulation air passage 18. The air that has reached the air outlet 145 passes through the bellows tube 29b (see FIG. 9) and flows into the air duct 66 (66c) (see FIG. 6). As indicated by broken line arrows in FIG. 5, the air flowing into the air duct 66 moves from left to right (from 66c to 66d to 66d) and is discharged from an air outlet (not shown) at the upper portion of the substantially triangular portion 66d. Is done.

  As shown in FIG. 8, the air discharged from the air duct 66 flows into the drying unit upper duct 61 from below through a drying filter (not shown). As shown in FIG. 11, the air flowing into the drying unit upper duct 61 is blown to the heater 62 by the drying fan 64 and heated.

  As shown in FIGS. 11 and 4, the air heated by the heater 62 of the drying unit upper duct 61 passes through the drying duct 22 and the bellows tube 29d, and as shown by the vertical arrows in FIG. As shown by a white arrow in FIG. 4, the air is discharged into the inner tank 9 through the wind inlet 146. As indicated by white arrows in FIG. 5, the air released into the inner tub 9 contacts the laundry C (on the pulsating blade board 11) in the inner tub 9 and warms the laundry.

  The air that warms the laundry is introduced into the inner tub 9 without passing through a water vent (not shown) at the bottom of the outer tub 10 when detergent liquid or water is stretched in the inner tub 9. The air rises along the inner surfaces of the inner tank 9 and the outer tank 10 by being pushed by the air. The air that has reached the outer tub cover 14 (inner lid 23) at the upper part of the washing tub flows into the through hole 158 of the outer tub cover 14 as shown by the white arrow in FIG. Then, it is heated again by the heater 62 through the same path. In this way, air circulates.

Next, the flow of air when the laundry is dried will be described.
Since there is no detergent solution or washing water in the inner tub 9 when the laundry is dried, the air is discharged from a water vent (not shown) at the bottom of the outer tub 10 by the drying fan 64 of the drying unit 60. . The air discharged from the water vent is taken into the air duct 66 through the joint 16 and the bellows pipe 68 (see FIG. 4).

  The air flowing into the air duct 66 is dehumidified by the internal cold water dehumidifying unit while moving from the bottom to the top of the first portion 66a. After leaving the contact with the cooling water, the air is discharged from an air outlet (not shown) at the upper part of the substantially triangular portion 66d (see FIG. 5).

  The air discharged from the air duct 66 moves in the same manner as when the laundry is preheated before the start of washing, and is discharged into the inner tub 9 (see FIGS. 6, 8, 9, and 11). The air released into the inner tub 9 comes into contact with the laundry in the inner tub 9 to evaporate the moisture of the laundry as water vapor, and is then discharged again from the water vent with the water vapor.

  The air and water vapor from which the laundry is dried are discharged from a water vent (not shown) at the bottom of the outer tub 10 and are heated again by the heater 62 through the same path. In this way, air circulates.

  Since the air outlet 145 is provided in the outer tank cover 14, it is structurally simple and easy to manufacture. Since the air discharge port 145 is located in the upper part of the washing tub, and the air discharge port 145 is not directly open to the washing tub, water hardly enters the air duct 66 and the like.

[mist]
As shown in FIG. 9, in the outer tub cover 14, a mist mesh 80 (miniaturized member) formed by weaving fine metal wires into a substantially hemispherical net shape is attached to the air outlet from the drying unit 60. As shown in FIGS. 8 and 11, a mist nozzle 70 protrudes downward from the drying unit upper duct 61 above the mist mesh 80. For example, the mist nozzle 70 is formed in a cylindrical shape having an inner diameter of about 1.5 mm, and is connected to the water supply electromagnetic valve 4 via the mist pipe 4b.

  When tap water is supplied to the mist nozzle 70 via the mist pipe 4b, the tap water sprayed downward from the mist nozzle 70 collides with the mist mesh 80, and the tap water is refined (misted). It is sprayed in the inner tank 9. Therefore, the mist nozzle 70 and the mist mesh 80 constitute a mist spraying device. Here, it is desirable that the mesh of the mist mesh 80 is rougher than a water supply filter (not shown) provided inside the connection port 4a (see FIG. 2). Thereby, it is possible to prevent the mist mesh 80 from being clogged with dust in tap water. Further, since the mist mesh 80 is arranged below the mist nozzle 70, the water sprayed from the mist nozzle 70 is accelerated by the gravitational acceleration and collides with the mist mesh 80. This can further promote the refinement of water.

Examples of the use of fine water (mist) include the following two points.
-Use 1: At the initial stage of washing the laundry, the laundry is moistened by spraying mist to make it easier to clean the laundry.
Application 2: When drying laundry after washing, the laundry is wrinkled by applying wind to the laundry while moistening the laundry by spraying mist.

[Control device]
FIG. 12 is a block diagram showing an electrical configuration of the washing / drying machine according to the present embodiment.
The washing / drying machine 100 according to this embodiment is controlled by a microcomputer 40 (microcomputer).
The microcomputer 40 is connected to an operation button input circuit connected to the operation button switch 6, a water level sensor, and a temperature sensor, and receives various information signals in the user's button operation, washing process, and drying process.
The microcomputer 40 is connected to a drive circuit and connected to the water supply electromagnetic valve 4, the drain valve 15, the drive device 13, the drying motor 63, the heater 62, and the like, and controls opening / closing, rotation, and energization thereof.
The microcomputer 40 is connected to a display, a light emitting diode, a buzzer, etc. of the operation panel 8 for notifying the user of the operation state of the washing / drying machine 100.

[Operation of washing dryer]
Next, the operation of the washing and drying machine according to the present embodiment will be described with reference to FIG. 13 with reference to the drawings described so far.
FIG. 13 is a flowchart showing control of the washing / drying machine according to the present embodiment.

  The microcomputer 40 confirms the state of the washing / drying machine 100 and performs initial setting when the user presses the power switch 5 to turn on the power (step S1).

  The microcomputer 40 turns on the display of the operation panel 8 and sets the washing / drying course according to the operation button switch operated by the user (step S2). If there is no setting, the standard washing / drying course or the previously executed washing / drying course is automatically set. For example, when the operation button switch is operated by the user, “washing and drying course” is set.

The microcomputer 40 determines whether or not an operation start is instructed by operating the operation button switch (step S3).
The microcomputer 40 repeats step S3 until the start of operation is instructed by operating the operation button switch (No in step S3). When the start of operation is instructed, the process proceeds to step S4 (Yes in step S3).

The microcomputer 40 first performs cloth amount sensing (step S4). In the cloth amount sensing, for example, the inner tub 9 is rotated at a low speed or accelerated to a specified rotational speed and measured from the current value of the electric motor of the driving device 13 at that time.
The microcomputer 40 displays the time until the washing / drying is completed and the amount of detergent based on the weight of the laundry calculated by the cloth amount sensing.
As a result, the user opens the lid 2 a and puts an appropriate amount of liquid detergent into the detergent / finishing agent container 28. Further, the user puts the softening finish into the detergent / finishing agent container 28 as necessary.

The microcomputer 40 generates a high concentration detergent solution (Step S5).
The microcomputer 40 opens the water supply electromagnetic valve 4, supplies water to the detergent / finishing agent container 28, dissolves the solid detergent, or dilutes the liquid detergent to generate a high-concentration detergent liquid. In addition, the produced | generated high concentration detergent liquid is stored in a washing tub (refer FIG. 2).

  The microcomputer 40 opens the water supply electromagnetic valve 4 and supplies the water necessary for the circulation of the high-concentration detergent solution or up to the top of the pulsating blade board 11 (step S6).

  The microcomputer 40 rotates the electric motor of the driving device 13 and stirs the inside of the inner tank 9 with the back blade 11 b of the pulsating blade 11. The high-concentration detergent liquid stirred by the back blade 11b ascends the circulation channel 9c formed on the inner peripheral surface of the inner tank 9, and is discharged into the inner tank 9 from the discharge port 9d. Since the discharge port 9d is located in the upper part of the inner tub 9, the high-concentration detergent liquid is sprayed on the laundry from the upper part of the laundry and penetrates into the laundry (step S7).

  The microcomputer 40 opens the water supply electromagnetic valve 4, rotates the drying fan 64 of the drying unit 60, operates the heater 62, blows high-speed air into the inner tank 9, and mist nozzles via the mist pipe 4 b. Tap water is supplied to 70, and the tap water is converted into hot water mist and sprayed on the laundry (step S8).

  The microcomputer 40 measures the temperature of the laundry, and if the temperature has not reached the predetermined temperature, the microcomputer 40 returns to step S7 and repeats the spraying of the high-concentration detergent solution and the warm water mist (No in step S9). The microcomputer 40 measures the temperature of the laundry, and proceeds to step S10 if the temperature reaches the predetermined temperature (Yes in step S9).

In order to perform the washing operation, the microcomputer 40 supplies water to the outer tub 2 to a specified water level (step S10).
The microcomputer 40 opens the water supply electromagnetic valve 4 and supplies water into the inner tank 9 from the water supply inlet 147 through the bellows tube 29c. Further, the microcomputer 40 opens the water supply electromagnetic valve 4 and supplies water to the detergent / finishing agent container 28 to wash the detergent / finishing agent container 28. The water that flows from the detergent / finishing agent container 28 flows between the outer tub 10 and the inner tub 9 (step S10).

The microcomputer 40 performs a washing operation.
The microcomputer 40 performs washing while rotating the electric motor 13a and alternately rotating the inner tank 9 and the pulsating blade 11 in the forward and reverse directions at a low speed (step S11).

The microcomputer 40 performs drainage / dehydration operation in order to remove washing water from the laundry.
The microcomputer 40 opens the drain valve 16 and drains the washing water in the outer tub 10, and then rotates the electric motor of the driving device 13 to rotate the inner tub 9 at a high speed, thereby centrifugally dehydrating the laundry (step S 12). ).

The microcomputer 40 closes the drain valve 16 and opens the water supply electromagnetic valve 4 to supply rinse water to the outer tub 10 to a predetermined water level.
When the water is supplied to a predetermined water level, the microcomputer 40 closes the water supply electromagnetic valve 4 and drives the electric motor of the driving device 13 to alternately rotate the rotating drum 3 in the forward and reverse directions at a low speed, thereby “rinsing” the laundry. Operation is executed (step S13).

  After the rinsing operation is finished, the microcomputer 40 opens the drain valve 16 and drains the rinse water in the outer tub 10, and then drives the electric motor of the driving device 13 to rotate the inner tub 9 at a high speed, thereby washing the laundry. Centrifugal dehydration is performed (step S14).

The microcomputer 40 closes the drain valve 16 and opens the water supply electromagnetic valve 4 to supply rinse water to the outer tub 10 to a predetermined water level.
When the water is supplied to a predetermined water level, the microcomputer 40 closes the water supply electromagnetic valve 4 and drives the electric motor of the driving device 13 to alternately rotate the rotating drum 3 in the forward and reverse directions at a low speed, thereby “rinsing” the laundry. Operation is executed (step S15).

  After the rinsing operation is finished, the microcomputer 40 opens the drain valve 16 and drains the rinse water in the outer tub 10, and then drives the electric motor of the driving device 13 to rotate the inner tub 9 at a high speed, thereby washing the laundry. Centrifugal dehydration is performed (step S16).

The microcomputer 40 determines whether or not the course selected in step S2 is a course including drying (step S17).
When the course selected in Step S2 is a course including drying (Yes in Step S17), the process proceeds to Step S18 and a drying operation is performed (Step S17).
If the course selected in step S2 is a course that does not include drying (No in step S17), the operation is terminated (step S17).

In the drying operation, the microcomputer 40 drives the drying fan 64 of the drying unit 60 at a high speed while rotating the inner tank 9 at a low speed, energizes the heater 62, and causes high-speed hot air to flow into the inner tank 9. Raise the temperature of the blown laundry and evaporate moisture from the laundry. The microcomputer 40 opens the water supply electromagnetic valve 4 and supplies cooling water to the cold water dehumidifying part of the air duct 66. The hot and humid air containing moisture evaporated from the laundry is dehumidified by the cold water dehumidifying portion of the air duct 66.
The completion of drying is detected by a temperature sensor (not shown), and the microcomputer 40 ends the drying operation when it detects the drying of the laundry (step S18).

The washing / drying machine 100 according to this embodiment can circulate the high-concentration detergent liquid by providing the inner tub 9 with the circulation flow path 9c without providing a pump that circulates the high-concentration detergent liquid. The washing / drying machine 100 according to the present embodiment connects the washing tub (outer tub 10) and the air duct 66 to ensure an air circulation path, and thus does not include a pump for circulating a high-concentration detergent solution. Can be warmed with warm air. Moreover, water is made into hot water mist with high-speed hot air, and sprayed on the laundry by spreading and spraying it on the laundry, along with the spraying of high-concentration detergent solution, on the dirt stuck in the laundry and the laundry behind the inner tub 9 Evenly spreads out and makes it easy to remove dirt. And since a washing operation is performed by supplying water, the detergency can be improved.
The washing / drying machine 100 according to the present embodiment includes a bellows tube having a simpler structure than the circulation pump to secure an air circulation path, and also uses water blowing means provided in the washing / drying machine to convert water into hot water mist. Therefore, it is possible to provide a washing / drying machine that can obtain a high detergency by an inexpensive method without increasing the cost.

  Note that the rinsing (step S13 to step S16) is performed twice in the flowchart shown in FIG. 13, but the combination of “water supply—rinsing—dehydration” may be performed once or a plurality of times.

Second Embodiment
The second embodiment will be described with reference to the drawings described so far as appropriate.
FIG. 14 is a schematic diagram illustrating a schematic structure of the washing / drying machine according to the second embodiment.
The second embodiment is a washing and drying machine provided with an air discharge port 101 on the upper rear side surface of the outer tub 10 and connected to the air duct 66 by a bellows tube 292.

  The outer tub 10 according to the second embodiment includes an air discharge port 101 at a position facing the air duct 66 on the upper rear side surface. The position of the air discharge port 101 is preferably a position where the distance between the outer tub 10 and the air duct 66 is the shortest. The air discharge port 101 is formed at a position above the level of the detergent liquid before the start of washing, that is, at a non-submerged position.

  The bellows tube 292 includes a bellows part connected to the air discharge port 101, a connection part connected to the air duct 66, and a conversion part between them, for example, as in 29b of the first embodiment. The conversion unit has an angle at which the connection with the air discharge port 101 is coaxial and the connection with the air duct 66 is coaxial.

[Ventilation route]
The ventilation path in 2nd Embodiment is demonstrated referring FIG.
The air in the inner tank 9 flows into the air duct 66 (66c) from the air discharge port 101 on the upper rear side surface of the outer tank 10 through the bellows tube 292 by the drying fan 64 of the drying unit 60 (see FIG. 14). . The air flowing into the air duct 66 moves from left to right (from 66c to 66a to 66d) and is discharged from an air outlet (not shown) at the upper portion of the substantially triangular portion 66d (see FIG. 5).

  The air discharged from the air duct 66 flows into the drying unit 60 through the same path as in the first embodiment and is dried. The dried air is discharged into the inner tank 9 through the same route as in the first embodiment (see FIGS. 4, 5, 9, and 11). The air released into the inner tub 9 comes into contact with the laundry C (on the pulsating blade 11) in the inner tub 9 and warms the laundry C.

  When the detergent C, water, or the like is stretched in the inner tub 9, the air that warms the laundry C cannot pass through the water vent (not shown) at the bottom of the outer tub 10, and passes through the inner tub 9 or through the inner tub 9. It passes along the hole 9a and rises along the inner surface of the outer tub 10. The air that has reached the inner lid 23 and the outer tub cover 14 at the upper part of the washing tub moves along the inner surface of the inner lid 23 (see FIG. 2) and reaches the air discharge port 101 on the upper rear side surface of the outer tub 10. . Then, the air is heated again by the heater 62 through the bellows tube 292 as described above. In this way, air circulates.

  The flow of air when the laundry is dried is the same as in the first embodiment.

  By providing the air discharge port 101 on the upper rear side surface of the outer tub 10, the air moving distance from the outer tub 10 to the air duct 66 is shortened and the blowing resistance is also reduced, so that energy efficiency and drying efficiency are improved.

<Third Embodiment>
The third embodiment will be described with reference to the drawings described so far as appropriate.
FIG. 15 is a schematic diagram illustrating a schematic structure of the washing / drying machine according to the third embodiment.
The third embodiment is a washing / drying machine in which an air discharge port 28 a is provided on the side surface of the detergent / finishing agent container 28 and connected to the air duct 66 by a connection pipe 681.

  The air discharge port 28a is provided in the detergent / finishing agent container 28 located above the washing tub, and is formed at a position above the level of the detergent liquid before the start of washing. The air discharge port 28a of the third embodiment is formed at a non-submerged position.

  The detergent / finishing agent container 28 and the air duct 66 according to the third embodiment are connected by a connecting pipe 681. Since the detergent / finishing agent container 28 and the outer tub cover 14 are connected by a bellows tube, in the third embodiment, the displacement caused by the swinging of the outer tub 10 (washing tub) is between the air duct 66 and the connection tube 681. Absorbing bellows tubes and bellows portions may not be provided.

[Ventilation route]
The ventilation path in 3rd Embodiment is demonstrated referring FIG.
The air in the inner tub 9 flows into the air duct 66 (66c) from the air discharge port 28a of the detergent / finishing agent container 28 through the connecting pipe 681 by the drying fan 64 of the drying unit 60 (see FIG. 15). The air that has flowed into the air duct 66 is dried by the same means and the same route as in the first and second embodiments, and discharged into the inner tank 9 (see FIGS. 4, 5, 9, and 11). The air released into the inner tub 9 comes into contact with the laundry C (on the pulsating blade 11) in the inner tub 9 and warms the laundry C.

  When the detergent C, water, or the like is stretched in the inner tub 9, the air that warms the laundry C cannot pass through the water vent (not shown) at the bottom of the outer tub 10, and passes through the inner tub 9 or through the inner tub 9. It passes along the hole 9a and rises along the inner surface of the outer tub 10. The air that has reached the outer tub cover 14 (inner lid 23) at the upper part of the washing tub moves along the inner surface of the inner lid 23 (see FIG. 2) and flows into the detergent / finishing agent container 28 from the bellows tube 29e. Then, it is heated again by the heater 62 through the same path. In this way, air circulates.

  The flow of air when the laundry is dried is the same as in the first embodiment.

  By connecting the detergent / finishing agent container 28 and the air duct 66 with the connecting pipe 681, it is possible to provide an air outlet more easily than providing the air outlet in the outer tank cover 14 or the outer tank 10, and the manufacturing cost is reduced. Reduction can be achieved. Durability is also expected to be improved by using a connecting tube that has a simpler structure than the bellows tube. Since the hot air introduction port 146 and the air discharge port can be separated from each other, the heating efficiency of the laundry is expected to be improved. Since the degree of freedom of the arrangement of the connecting pipe is also high, manufacturing can be easily performed.

  As described above, the present invention has been described in detail with reference to the embodiment of the washing and drying machine. Needless to say, the contents of the present invention are not limited to the above-described embodiment, and can be appropriately added, deleted, changed, and the like without departing from the spirit of the present invention.
