Nozzle 260 has towards the slow circular hollow shape of curved section in the front of nozzle 260, the shape that top end part 260a is set as the front side of nozzle 260 and the inclined top of rear side attenuates.On the top of nozzle 260, it is formed with the blow-off outlet 261 in the rectangular slit-shaped of the left and right directions extension of nozzle 260.In the present embodiment, the opening direction D of blow-off outlet 261 is for example set as 30 degree to 60 degree of range relative to the axis direction L of the nozzle 260 opening angle β formed.
In the upper end of nozzle 260, it is provided with circular flange part 262.Nozzle 260 is installed on the first introducing port 22b of outer barrel cover 22 using flange part 262 from below.Nozzle 260 is connected to the lower end of the first import pipe 230 via the first introducing port 22b.
In the state that nozzle 260 is installed on outer barrel cover 22, the axis direction L of nozzle 260 is parallel with vertical direction, as a result, the blow-off outlet 261 of nozzle 260 there is opening angle β since vertical direction and obliquely downward to.When the opening angle β of blow-off outlet 261 is too small, that is, when the opening direction D of blow-off outlet 261 gets too close to underface, the downward impetus of the wind blown out from blow-off outlet 261 is become too strong, and washings moves up and down variation.On the other hand, when the opening angle β of blow-off outlet 261 becomes excessive, that is, when the opening direction D of blow-off outlet 261 gets too close to horizontal direction, the downward impetus of the warm wind blown out from blow-off outlet 261 is become too weak, and the fold of aftermentioned washings smooths effect and becomes smaller.As a result, as described above, the opening angle β of blow-off outlet 261 is set as 30 degree to 60 degree of range preferably.
In turn, it as shown in fig. 6, nozzle 260 is on the top of Washing dewatering tub 24, in a manner of avoiding balance ring 25, is configured near the inner wall 24a of Washing dewatering tub 24.Then, the direction of the center P when direction of nozzle 260 is set as its blow-off outlet 261 to Washing dewatering tub 24 viewed from above not towards impeller 26 is open.That is, the clockwise direction of Fig. 6 to be set as to the forward rotation direction A of impeller 26, when the counter clockwise direction of Fig. 6 to be set as to the reverse directions B of impeller 26, blow-off outlet 261 is towards the side forward rotation direction A.It should be noted that blow-off outlet 261 can also be towards the side reverse directions B.In addition, as shown in the ellipse of Fig. 6 bend, blow-off outlet 261 be towards target half, the length outer peripheral side of 1/2R i.e. shown in fig. 6 since the center P of impeller 26 region.
Then, the movement of fully-automatic washing machine having drying means 1 is illustrated.
In fully-automatic washing machine having drying means 1, the washing operating, washing and drying operating or drying operating of various operation modes are carried out.Washing operating is the operating only washed, and executes washing process, intermediate dehydration, rinse cycle and final dewatering process in order.Washing and drying operating is to be carried out continuously the operating of washing to drying, and then final dewatering process executes drying course.Drying operating is the operating only dried, and only executes drying course.
In washing process and rinse cycle, in water accumulation in the state of in Washing dewatering tub 24, impeller 26 is rotated to forward rotation direction A and reverse directions B.Water flow is generated by being rotated in Washing dewatering tub 24 for impeller 26.In washing process, washings is cleaned by detergent contained in generated water flow and water.In rinse cycle, washings is rinsed by generated water flow.
During intermediate dehydration and final dewatering, Washing dewatering tub 24 and impeller 26 integrally high speed rotation.Washings is dehydrated by the effect of the centrifugal force generated in Washing dewatering tub 24.
During the drying process, pressure fan 200 and heater 220 are acted in drying unit 50.The wind of high speed is sent out as the first wind from pressure fan 200 to ventilation pipe 210.The first wind sent out to ventilation pipe 210 flows mainly through the first wind path 211 and flows out from the first outflux 214, passes through the first import pipe 230 and reaches nozzle 260 (referring to Fig. 4 (a) solid arrow).Then, the first wind is blown out fiercely from the region of blow-off outlet 261 towards the bottom of Washing dewatering tub 24, the peripheral side of impeller 26 i.e. shown in fig. 6 of nozzle 260.In the present embodiment, flow velocity, the i.e. initial flow velocity of the warm wind just blown out from the blow-off outlet 261 of nozzle 260 are 100m/s or so.It should be noted that initial flow velocity is set as 50m/s or more, it is preferably set to 80m/s or more preferably.In this way, the warm wind blown out from blow-off outlet 261 is greatly enhanced compared to the warm wind impetus blown out in previous drying course to flow velocity 20m/s in Washing dewatering tub 24 or so.
On the other hand, it in the first wind sent out to ventilation pipe 210, is guided plate 216 across a part of wind for separating 213 side of wall surface and stops, reduce its flow velocity and towards opening portion 215, flowed out from opening portion 215 into the second wind path 212.A part of wind flowed out from opening portion 215 is heated by heater 220, becomes such as 80 DEG C or so of high temperature of the second wind, and flow through the second wind path 212, is flowed out from the second outflux 218.The second wind flowed out from the second wind path 212 passes through the second import pipe 240, is imported into outer barrel 20 from the second introducing port 22c, i.e. (reference Fig. 4 (a) dotted arrow) in Washing dewatering tub 24.
In Washing dewatering tub 24, impeller 26 repeats the rotation of forward rotation direction A and the rotation of reverse directions B.
Fig. 7 (a) and Fig. 7 (b) is the figure for schematically showing movement of the washings in Washing dewatering tub 24 in the drying course of present embodiment.In Fig. 7 (a) and Fig. 7 (b), impeller 26, nozzle 260 and washings are only drawn out.
When impeller 26 rotates, as shown in Fig. 7 (a), washings is pushed by the blade part 110 of impeller 26 on one side, slides onto the inclined surface 112 of blade part 110 on one side, is overturn as a result, by the top of the direction of travel to blade part 110.In the case where impeller 26 is rotated to forward rotation direction A, the first wind from nozzle 260 blows to washings from the contrary direction to move ahead with the washings of overturning fiercely.As shown in Fig. 7 (b), on washings, the blowing force of acceleration and warm wind to direction of travel acts on opposite direction, therefore washings is unfolded in the horizontal direction by these power, and the fold of washings is smoothed.Herein, when being stirred by impeller 26, although washings is easy to gather the peripheral side of impeller 26 by centrifugal force, due to nozzle 260 blow-off outlet 261 be towards target impeller 26 peripheral side region, warm wind readily access peripheral side overturning washings.
In turn, it by the second wind of the high temperature imported from the second introducing port 22c, is heated in outer barrel 20, i.e. in Washing dewatering tub 24, thus washings is oven-dried.
