A jet duct 25 is connected to the tip of the upper bellows-shaped hose 24 and opens toward the inner tank 14. Since the inner tank 14 communicates with the outer tank 13 through the dehydration holes 16 on the peripheral wall, these passages form a circulation path.

The cooling blower 26 is attached to the side surface of the housing 11 and is configured to cool the lower portion of the inner tank 14 and the circulation duct 21. The drain valve 27 drains the water in the outer tub 13 through the drain hose 28.

The water supply case 29 has a water supply port 29a serving as an inlet thereof connected to the water supply by a water supply hose 30, and has two water channels at the outlet. One channel is a water channel 29b for supplying washing water into the outer tub 13, and the other channel is a spray nozzle 32 through a tube 31.
It is a water supply channel 29c for spraying leading to.

A water supply valve 33 is provided at the inlet of the water supply passage 29b to turn ON / OFF the water supply to the water supply passage 29b. Further, the spray valve 3 is provided at the inlet of the spray water supply passage 29c.

The spray nozzle 32 turns on the spray valve 34.
The water supply hose 30, the water supply case 29,
It is connected to the water supply through the water supply channel 29c for spraying and the tube 31, and the fog is sprayed from the spraying port 32a by the water supply pressure into the inner tank
It is configured to eject inward and is attached to the upper portion of the outer tub 13.

The control means 35 includes a drive means 18, a drying blower 22, a heater 23, a cooling blower 26, a drain valve 27,
Washing by controlling the operation of the water supply valve 33 and the spray valve 34,
Control rinsing, dehydration and drying processes. Further, the cloth amount detecting means 36 detects the amount of clothes in the inner tub 14,
It is a part of the control means 35.

The operation of the above configuration will be described. First,
In the washing process, the water supply valve 33 is turned on until the control means 35 reaches a predetermined water level to supply the water supply hose 30 and the water supply case 2.
The washing water is supplied into the outer tub 13 via the water supply passage 9b and the water supply passage 29b. Next, the inner tank 14 is a rotatable clutch 18b.
In this state, the driving means 18 is driven to rotate the inner tub 14 containing clothes and washing water.

At this time, the drain valve 27 is closed. As a result, the outer peripheral portion of the wash water in the inner tub 14 rises due to the centrifugal force. Along with this, the washing water between the inner tub 14 and the outer tub 13 rises along the inner wall of the outer tub 13, and then the inner tub 1
Water will be sprinkled from the upper part of 4 into the inner tank 14 and circulated. As a result, the washing water passes through the clothes in the inner tub 14 and is washed.

After that, the clothes are rinsed and rinsed in the same manner as the washing process, and in the dehydration process, the drain valve 27 is opened to drain the water from the drain hose 28, and the inner tank 14 is in the rotatable clutch 18b state. , Drive means 18
Is driven to rotate the inner tub 14 containing the clothes at a high speed. Due to the centrifugal force generated by this, the clothes are pressed against the inner wall of the inner tank 14, and the water is separated from the clothes by this centrifugal force to escape from the dehydration hole 16 to the outer tank 13, and the drain hose 2
The water is drained from No. 8 and the dehydration process proceeds.

In the drying process, the control means 35 controls the drying blower 22, the heater 23, the cooling blower 26 and the drain valve 2.
7 is controlled as described below. The upper bellows-shaped hose 2 is generated by the air blow of the drying blower 22 and the heat generation of the heater 23.
4. Dry hot air is blown into the inner tank 14 through the ejection duct 25. The warm air sent to the inner tank 14 removes water from the clothes when passing through the gaps between the clothes, and in a wet state,
After exiting from the inner tank 14 to the inside of the outer tank 13, it passes through the lower bellows-shaped hose 20 and reaches the circulation duct 21.

When hot air containing moisture is passing through the inner wall of the outer tub 13 and the circulation duct 21, the cooling blower 26
As a result, the lower part of the outer tub 13 and the outer wall of the circulation duct 21 are cooled, the moisture of the moist air is condensed on the inner wall, and the moist warm air is dehumidified and returns to the drying blower 22. The water condensed on the inner walls of the outer tub 13 and the circulation duct 21 is discharged from the drain hose 28 by opening the drain valve 27 as needed.

After the completion of the drying process, the heater 23 is turned off, and the blowing process for driving the drying blower 22 and the cooling blower 26 is performed to cool down the dried clothes and the process is finished. Here, an air-cooling dehumidification system using cooling air as a means for cooling the moist hot air is used, but a water-cooling dehumidification system may be used.

In the drying process, the control means 35 controls the driving means 18 and the spray valve 34 as described below. When the washing process is completed and the drying process is started, first, since the clothes are attached to the wall surface of the inner tub 14 by the final dehydration of the washing process, the cloth peeling process is performed. Specifically, the drive means 18 is rotated in the normal direction while the stirring blade 15 is in the state of the rotatable clutch 18b, and the stirring blade 15 is reciprocated three times.

By doing so, the clothes adhered to the wall surface of the inner tub 14 at the time of dehydration are peeled off, and the cloth volume of the clothes is increased to increase the contact area with the air, so that the subsequent drying progresses quickly. To be At this time, at the same time, the cloth amount detecting means 36 detects the inertial rotation amount when the motor 18a of the driving means 18 is turned off.
Detect the amount of clothes inside.

Next, the clutch 18 in which the inner tank 14 is rotatable
In the state of b, the driving means 18 is rotated and the inner tank 14 is rotated and dried for a predetermined time. Next, the rotation of the inner tank 14 is stopped, and the driving means 18 is rotated while the stirring blade 15 is in the state of the rotatable clutch 18b.
A stirring mode in which the stirring blades 15 are dried while being rotated in the normal direction is performed for a predetermined time to stir the clothes and the clothes are switched up and down.

Then, the tank rotation mode is performed again, and thereafter, the tank rotation mode and the stirring mode are sequentially repeated.
As the drying progresses, the tank rotation mode time is shortened and the agitation mode time is lengthened to increase the frequency of changing clothes and to proceed the drying efficiently.

When the drying process is near the end, the control means 3
In No. 5, while spray valve 34 is intermittently turned on, mist is jetted from the spray port 32a of the spray nozzle 32 by the water pressure to evenly damp clothes in the inner tub 14 for drying. The flow rate of water flowing into the spray nozzle 32 at this time is detected by the flow rate detection means 37, and the control means 35 sets the spray valve 34 so that the spray amount per unit time becomes constant based on this flow rate. Turn on intermittently.
Further, the spray amount per unit time is assigned as shown in Table 1 based on the cloth amount detected by the cloth amount detecting means 36 in the cloth peeling process.

[0040]

[Table 1] As described above, according to the present embodiment, since a small amount of mist-like water ejected from the spray nozzle in the drying process can uniformly dry the clothes in the inner tank while moistening the thin and thick materials. Even if the clothes of different types are mixed or the amount of clothes is large, it is difficult to make uniform contact with warm air to the clothes, and even if the drying speed is different between clothes, overdrying is suppressed, sticking of wrinkles is suppressed, and the texture is kept. By making it better, the finished state of the clothes can be improved.

Further, since this spray nozzle is constructed so as to atomize water by tap water pressure, no special means such as a pump for raising the pressure in the spray nozzle is required, so that it is very convenient. The fog can be ejected with a simple structure.

Also, turning on the water flow into the spray nozzle
Turn the spray valve to turn on / off and supply water to the outer tub of washing water.
Since there is a water supply valve for turning on / off and these are integrally formed, there is only one water supply port from the water supply, and the switching between water supply in the washing process and spray of mist in the drying process is performed by the water supply valve and the spray valve. It can be performed only by turning ON / OFF, and a simple water channel configuration can be achieved, and mist can be jetted at an arbitrary timing by the spray valve.

According to the experiments by the inventors, even if the mist is not blown from the initial stage of drying when the clothes are sufficiently moist,
It has been found that spraying a mist near the end of drying clothes can prevent the clothes from overdrying and improve the finished state. Therefore, for example, by turning on the spray valve only near the end of the drying process, overdrying of clothes is suppressed and wrinkles are fixed while minimizing the extension of the drying time due to humidifying clothes. Hold down
By improving the touch, it is possible to improve the finished state of the garment.

Further, based on the flow rate detected by the flow rate detecting means, the spray amount per unit time becomes constant,
Since the control means intermittently turns on the spray valve, it is possible to always ensure an optimum spray amount per unit time even when the water pressure is not constant and the flow rate is unstable.

The control means intermittently turns on the spray valve so that the spray amount per unit time can be changed according to the amount of clothes detected by the cloth amount detecting means. If the amount of clothing is small, the amount of spraying per unit time is large. If the amount of clothing is small, the amount of spraying per unit time is also small. It is possible to secure an optimum spray amount according to the amount of.

In this embodiment, the inner bottom of the inner tank is provided with a stirring blade for stirring the clothes, but the invention is not limited to this, and the drum type washer / dryer does not have a stirring blade. Also has the same effect. At this time, the cloth amount detecting means detects the amount of clothes in the inner tank by rotating the inner tank instead of the stirring blade.

(Embodiment 2) As shown in FIG. 1, the control means 35, when the spray valve 34 is turned on in the drying process,
The driving means 18 is controlled so as to rotate the stirring blades 15 in synchronism with each other, and while the clothes are switched up and down, a mist is sprayed to evenly moisten the entire clothes. The other configurations are similar to those of the first embodiment, and the description thereof will be omitted.

As described above, according to the present embodiment, since the mist can be blown by rotating the stirring blades and rotating the clothes up and down, the clothes in the inner tank are dried more uniformly while being moistened. It is possible to suppress overdrying of the clothes more uniformly, to prevent wrinkles from sticking, and to improve the feel of the clothes, so that the finished state of the clothes can be improved.

(Embodiment 3) As shown in FIG. 2, the spray outlet 32a of the spray nozzle 32 is attached to the spray duct 25, which is in the air passage of the air blown into the inner tank 14, The mist ejected from 32 is configured to be widely diffused in the inner tub 14 by riding on the flow of air blown into the inner tub 14 by the blowing means 22. The other configurations are similar to those of the first embodiment, and the description thereof will be omitted.

As described above, according to the present embodiment, since the ejection port 32a of the spray nozzle 32 is provided in the air blowing path of the air blown into the inner tank 14, the spray nozzle 32 ejects the air during the drying process. The mist is widely diffused in the inner tub 14 and can even more uniformly dry the clothes in the inner tub 14 while being dried, so that the clothes are more uniformly prevented from being overdried and wrinkles are prevented from sticking. By improving the touch, it is possible to improve the finished state of the garment.

(Embodiment 4) As shown in FIGS. 3 and 4,
The jet outlet 32a of the spray nozzle 32 is provided on the upstream side of the heating means 23 in the air blowing path of the air blown into the inner tank 14, and the humidity detecting means 38 is provided in the jet duct 25. The humidity of the air blown into the inner tank 14 is detected. Other configurations are the same as those of the first embodiment,
The description is omitted.

FIG. 4 shows the humidity detecting means 3 as the drying progresses.
Change in humidity detected by 8 and control means 3 at that time
5 shows the control of the spray valve 34 by No. 5. As shown in FIG. 4, when the drying is near the end and the water content in the inner tank 14 decreases, the humidity in the circulation path decreases, so the humidity of the air blown into the inner tank 14 also decreases. . Then, when the humidity drops to H1 (%), the control means 35 turns on the spray valve 34.

As a result, the mist ejected from the ejection port 32a of the spray nozzle 32 rides on the flow of air blown by the blower means 22 and comes into contact with the heating means 23, and once vaporizes to become vapor. Finer water particles spread more widely within 14 to evenly moisten the garment. At this time, since moisture is replenished, the humidity of the air blown into the inner tank 14 increases.

Thereafter, the control means 35 intermittently turns on the spray valve 34 so that the humidity becomes, for example, H2 (%) or more, and as shown in FIG. 4, the range of H2 (%) to H3 (%). Repeat ON and OFF with to finish drying.

As described above, according to the present embodiment, the mist ejected from the spray nozzle 32 rides on the flow of air blown by the blower means 22 and comes into contact with the heating means 23, and once evaporated, it becomes vapor. Since fine water particles are widely dispersed in the inner tub 14 and the clothes in the inner tub 14 can be dried more uniformly while being moistened, overdrying of the clothes can be suppressed more uniformly and wrinkles are fixed. The finished state of the garment can be improved by suppressing this and improving the touch.

Further, it is possible to measure the degree of dryness of the entire garment by the humidity detecting means 38, and the control means 35 causes the spray valve only after the appropriate degree of dryness of the entire garment, which is a humidity below a predetermined value, is reached. Since 34 is not turned on,
While minimizing the extension of the drying time by giving moisture to clothes, it can improve the finished condition of clothes by suppressing overdrying of clothes, suppressing sticking of wrinkles, and improving the touch. it can.

Further, the control means 35 is arranged so that the humidity of the air detected by the humidity detection means 38 becomes a predetermined value or more.
Since the spray valve 34 is intermittently turned on, the moisture applied to the clothes can be maintained at a stable and appropriate amount.
