As be shown in Fig. 3 ground, and above water jacket 2, set air-supply arrangement 22, at the suction inlet of the blower-casting 22a of this air-supply arrangement 22, be connected to form dry wind outlet 39 (with reference to Fig. 1) in heat exchange unit 21 and heat exchanger 31 upper ends.

In the air-supply arrangement 22, the fan 22c (with reference to Fig. 2) that is equipped in the blower-casting 22a is rotated driving by fan motor 22b.At air-supply arrangement 22, air-supply arrangement is installed with rotation speed sensor (not shown), can detect the rotary speed of fan motor 22b and carry out speed control.

Above water jacket 2, an end of heater 23 is connected in the outlet of blower-casting 22a.This heater 23 possesses the warm braw that is made of for example PTC (Positive Temperature Coefficient, positive temperature coefficient) heater and generates with heater 23b (with reference to Fig. 2) in the heater housing 23a of the gabarit that constitutes heater 23.

The so-called dry wind generation unit that is constituted by air-supply arrangement 22 and heater 23 makes the dry wind that has carried out the water-cooled dehumidifying with heat exchanger 31, be regenerated as new dry wind by the air-supply effect of air-supply arrangement 22 and the heat effect of heater 23, and pass out to the flexible pipe 24 in downstream.

The other end of flexible pipe 24 as being connected in the upper end of the air supply pipe 25 that is arranged at water jacket 2 upper rear portion with being shown in Fig. 3, and this air supply pipe 25 is connected in the air supply opening 2b of water jacket 2.

With reference to Fig. 4, illustrate with the relation of the dry wind air quantity of flow through heat exchange unit 21 and shunt access 32 about the rotary speed of fan 22c (fan motor 22b).

As be shown in Fig. 4 ground, along with fan revolution speed is accelerated, the dry wind air quantity of flow through heat exchange unit 21 and shunt access 32 all increases gradually.Also have, the flow through increment of dry wind air quantity of shunt access 32 of the incremental raio of the dry wind air quantity of the heat exchange unit 21 of flowing through is big.This is because shunt access inlet 32a is narrow, does not increase so do not cause the air quantity that is directly proportional.

Next, the work about the dry operating of the things that are dried such as clothing in the drum-type washing drying machine in the present embodiment 1 describes.

At first, running effect about scrubbing-and-drying unit 1, as knownly in the running stroke of standard, the center that is controlled to be with the rotary speed of the cylinder 8 that is directly connected in motor 17, automatically carry out washing, rinsing, each running of dehydration, washing function intermediate roll 8 hereto is driven in rotation, and the water jacket 2 that forms the space that is closed substantially works as tank.

In the time of in the water jacket 2 when water is supplied in the washing running from tripartite feed water valve 29, measure each output of fixing time of the running water pipe (water source) be connected in scrubbing-and-drying unit 1 by flowmeter 29a (with reference to Fig. 2), this measurement result is input into control device 7 and can differentiates as described above is that 3 ranks are stored (the little water yield, the standard water yield, big yield).And change dry operating at last into.

Though cylinder 8 similarly is driven in rotation, water jacket 2 works as the hothouse of getting dry wind into, makes the washings dryings such as clothing in the cylinder 8.Below, at length describe about the action of this dry operating.

Control device 7 makes work such as heat exchange unit 21, air-supply arrangement 22, heater 23 and can carry out dry wind is supplied in dry operating in the water jacket 2 continuously.The dry wind that is illustrated in circulation in the peripheral passage 3 by the dotted arrow A～I among Fig. 2, Fig. 3 flows to.

Also have, though in Fig. 2 the part of peripheral passage 3 is omitted, for the continuity of representing dry wind flows to, dotted arrow is mark continuously.Below, describe in proper order according to the symbol of representing dotted arrow A～I that dry wind flows to.

The dry wind that is used to carry out in water jacket 2 after the drying of clothing etc. is discharged as the exhaust outlet 2a of the discharge wind that comprises moisture from top, the place ahead.Then, by blast pipe 19, in screen pipe 20, rearward flow (dotted arrow A).

If comprise Soft flocks etc. in the dry wind that flows this screen pipe 20 in, then this Soft flocks etc. place the 26 interior filter element 26a of portion by filter and capture.

Through the pipe section 20a of chimney filter 20 flow to the rear and the dry wind that arrives rear end connector 20b in sag pipe 27 towards below flow (dotted arrow B, C).Next, dry wind enters in the heat exchange unit 21 (dotted arrow D) from the connected entrance 28 (with reference to Fig. 1) of sag pipe 27, heat exchange unit 21 in towards above mobile (dotted arrow E).

In heat exchange unit 21, the dry wind (dotted arrow E) that flows towards the top is shunted, and a side flows to path in the heat exchanger 31 from path inlet 31a, and the opposing party flows to shunt access 32 from the shunt access 32a that enters the mouth.

In heat exchanger 31, supplied with and the water that injects from water filling port 34 flows down slowly along the said spiral shape protuberance that is made of a plurality of rib shape portion 33 that is arranged at path internal perisporium face by tripartite feed water valve 29.Therefore, this water that flows down longer time ground contacts with the dry wind that flows in heat exchanger 31 paths and promotes heat exchange.

Thus, dry wind is cooled effectively, and the moisture that is contained in dry wind is dewfall more, and moisture in the dry wind and/or moisture are dehumidified.After this, dry wind is discharged upward from the dry wind outlet 39 as heat exchange unit 21 and heat exchanger 31, flows in the blower-casting 22a (dotted arrow F).

In addition, in the present embodiment the output from the running water pipe (water source) in when running washing is measured, its measurement result is stored in control device 7.Corresponding to measurement result is one of " big yield ", " the standard water yield ", " little water yield ", and the water yield also change certainly in the heat exchanger 31 is arrived in water filling.

Therefore control device 7 can carry out as inferior control: the air-supply arrangement 22 of the basic air quantity that produces dry wind is carried out rotary speed control corresponding to above-mentioned differentiation result, for example obtain setting, and the increase and decrease of whole air quantity is adjusted for the raising of seeking drying property with the air quantity of the effective heat exchange performance of water yield equilibrium corresponding to the carrying out of dry operating.

Also have, outside (cloth drying) machine, discharge by drainpipe 36 from water discharge outlet 35 by the water of water in annotating heat exchanger 31 that above-mentioned dewfall produces.

On the other hand, the dry wind that flows in shunt access 32 does not cause heat exchange action by water filling, thereby flows to (dotted arrow F) in the blower-casting 22a not by dehumidifying from the dry wind outlet 39 as heat exchange unit 21 and heat exchanger 31.

The dry wind of being discharged from heat exchanger 31 paths and shunt access 32 blows side out to heater 23 after being sucked in the blower-casting 22a of air-supply arrangement 22, is heated (dotted arrow G) at this by aforementioned heater 23b (with reference to Fig. 2).

The dry wind that has been heated is supplied in the water jacket 2 from air supply opening 2b by flexible pipe 24 (dotted arrow H), air supply pipe 25 (dotted arrow I).Then, contact with clothing in the cylinder 8 of rotation etc. and make drying such as clothing, the dry wind that is used for after dry is discharged from exhaust outlet 2a.

So, supply with dry winds, the be dried clothing etc. of thing of the conducts in the drying drum 8 by circulation in the external groove 2.

According to above formation, the scrubbing-and-drying unit 1 in the present embodiment has following effect.

Because be provided with shunt access 32 with heat exchanger 31 paths with being in side by side relationship, so dry wind splits into heat exchanger 31 paths and shunt access 32 these two paths at the entrance side of heat exchanger 31 and passes through, be sent to dry wind generation unit side, be regenerated as new dry wind and be recycled at this and be supplied in water jacket 2.

, as in the prior art, only possessing under the situation of heat exchanger passages, if raising drying efficiency and increase air quantity, then because cooling water is kicked up singularly, so the water spittle might arrive the fan and/or the heater in downstream.

On the contrary, under the situation that air quantity becomes few, the water spittle of the heat exchanger internal upper part of kicking up becomes vaporific, and it becomes the resistance that dry wind flows easily, might further hinder flowing of the interior wind of heat exchanger.

But the dry wind air quantity of heat exchanger 31 paths of flowing through in the present embodiment can reduce the amount that flows to shunt access 32 sides at least.

Thereby, can prevent to make the phenomenon that the water spittle is kicked up unusually owing to the dry wind that comes the path in the automatic heat-exchanger 31, can guarantee electric security.

And, because flow to the dry wind resistance ratios of shunt access 32 less, do not have a heat exchange action certainly yet, so flow swimmingly, whole air quantity is descended to improve on the contrary, and can prevent as the above-mentioned water spittle phenomenon of kicking up.

And can guarantee circulates is supplied in the predetermined dry air quantity of water jacket 2, and the drying efficiency of scrubbing-and-drying unit 1 also is improved, and can further shorten the dry operating time.

Also have, though in the present embodiment, illustrate heat exchanger 31 paths and shunt access 32 are integrally formed in example in the heat exchange unit 21, be not limited to this, heat exchanger 31 paths and shunt access 32 also can be distinguished formation independently.

And also needn't form as one with heat exchange unit 21 as shown in this embodiment about sag pipe 27, they also can be the formation that forms independently of one another and be connected.

With respect to above-mentioned embodiment, Fig. 5～Figure 11 represents the 2nd～the 4th embodiment of the present invention, for the additional prosign of identical with above-mentioned the 1st embodiment in fact part explanation is omitted, and describes about difference.

(the 2nd embodiment)

Fig. 5 is the figure suitable with Fig. 1 of expression the 2nd embodiment of the present invention.As be shown in Fig. 5 ground, entrance side at the heat exchange unit 21 that constitutes heat exchanger 31 paths and shunt access 32 connects sag pipe 51, and the short circuit path 52 that the dry wind that short circuit is communicated in heat exchange unit 21 and heat exchanger 31 exports 39 sides is formed at the side wall upper part of sag pipe 51.

In the present embodiment,, and make its sidewall become common wall, so only just can form short circuit path 52 by forming intercommunicating pore because sag pipe 51 forms as one with heat exchange unit 21.

Next, about the work of the dry operating in the present embodiment, also describe with reference to Fig. 2, Fig. 3 of representing identical formation.

In sag pipe 51 will towards below the part of the dry wind (dotted arrow C) that flows flow to the short circuit path 52 that is formed at sag pipe 51 side wall upper part, and near the dry wind outlet 39 of heat exchange unit 21, flow into.

Thereby this dry wind had not both had heat exchange action and without shunt access 32 ground, had directly flowed into (dotted arrow F) from dry wind outlet 39 in blower-casting 22a.

Also have, other dry wind flows in the heat exchange unit 21 (dotted arrow D) from the connected entrance 28 of the foot that is formed at sag pipe 51, with the illustrated shunting similarly of above-mentioned the 1st embodiment flow to heat exchanger 31 paths and shunt access 32 after, discharge from the shared dry wind outlet 39 on top, in blower-casting 22a, flow into (dotted arrow F).

Thereby, export near 39 fronts because aforementioned short circuit path 52 also is communicated in dry wind, so the whole dry winds after the shunting are discharged from a dry wind outlet 39.

According to above formation, the scrubbing-and-drying unit 1 in the present embodiment also has following effect except with the effect shown in the 1st embodiment.

According to the scrubbing-and-drying unit in the present embodiment 1, then be formed with the short circuit path 52 that dry wind that short circuit is communicated in heat exchanger 31 exports 39 front sides in sag pipe 51 side wall upper part.

Thus, a part that flows to the dry wind of sag pipe 51 is supplied in water jacket 2 by short circuit path 52 via peripheral passage 3.Because short circuit path 52 is formed at sag pipe 51 side wall upper part, therefore be supplied in the dry wind of water jacket 2 and compare via the dry wind that heat exchange unit 21 sides are supplied in water jacket 2 via short circuit path 52 by connected entrance 28, fan resistance is little and easy to be mobile, increases so circulation is supplied in the whole air quantity of the dry wind of water jacket 2.

Thereby, even from the dry wind of shunt access 32 and/or heat exchanger 31 passage side mobile because of some former thereby variation, also because replenished, so the whole air quantity of the dry wind that circulates can not reduce from short circuit path 52, not only can guarantee aequum, can also increase.

So, the scrubbing-and-drying unit 1 in the present embodiment so the drying efficiency of washings improves, can shorten the dry operating time because the circulated air circulation of sufficient quantity can be supplied in water jacket 2.

(the 3rd embodiment)

The 3rd embodiment that is shown in Fig. 6～Figure 10 is characterized as: especially be provided with the long-pending catch 62 (path changing cell) for changing of passage sections of the shunt access 32 that makes heat exchange unit 61 (being equivalent to heat exchange unit 21 in the 1st embodiment), below describe in detail.

Fig. 6 is the figure suitable with Fig. 1 of expression the 3rd embodiment of the present invention.Fig. 7 is the air quantity characteristic figure of aperture with the relation of the dry wind air quantity of path that flows to heat exchanger 31 and shunt access 32 of expression shunt access 32.Fig. 8 is that expression is followed in the dry wind characteristic of the carrying out of dry operating and the performance plot of shunt access 32 apertures variation separately.Fig. 9 is the performance plot of the air quantity characteristic of each stroke of expression running etc.Figure 10 is used for the Action Specification figure that the aperture to the dry wind air quantity that flows to heat exchanger passages and shunt access 32 corresponding to the cooling water amount that is supplied in heat exchanger 31 and shunt access 32 describes.

As be shown in Fig. 6 ground, form the lower end of the partition wall 30 of shunt access 32 separating heat exchange unit 61, inject rotating shaft 62a from the outside (diagram rear side) of heat exchange unit 61 by the stepping motor (not shown) of control device 7 (with reference to Fig. 2) institute drive controlling.

Catch 62 be shaped as basic and the identical shaped square plate body of peristome, one side catch 62 be mounted on rotating shaft 62a, catch 62 is that back and forth rotate along the direction of arrow at the center with rotating shaft 62a.

Rotate by catch 62, shunt access inlet 32a can be opened and closed, the passage sections long-pending (aperture of shunt access 32) of shunt access 32 can be changed.

When the base of catch 62 was the state of contact sag pipe 51 sidewalls (it is the sidewall of heat exchange unit 21, is again the sidewall of shunt access 32), the aperture of shunt access 32 was 0%, and promptly the passage sections of shunt access 32 is long-pending is zero.

When catch 62 and partition wall 30 were positioned at state on the straight line, the aperture of shunt access 32 was 100%, and promptly the passage sections of shunt access 32 is long-pending for maximum.Just, the aperture minimum is not 0% in the present embodiment, and is set at roughly 30%, and always part is open and be in connected state.

Though in the present embodiment, the stepping angle of aforementioned stepping motor has for example used 1 degree, is not limited to this, for example also can change to 3 and spend or various angles such as 5 degree and use stepping angle.Stepping angle is more little, can control the aperture of shunt access 32 more subtly.

Next, illustrate with the relation of the dry wind air quantity that flows to heat exchanger 31 paths and shunt access 32 about the aperture of shunt access 32 with reference to Fig. 7.

As be shown in Fig. 7 ground, and along with the aperture increase of shunt access 32, the dry wind air quantity that flows to heat exchanger 31 paths reduces gradually, and the dry wind air quantity that flows to shunt access 32 increases gradually.

Also have,, flow to heat exchanger 31 paths and all equate substantially with the dry wind air quantity that flows to heat exchange unit 61 with the dry wind air quantity sum of shunt access 32 no matter how many apertures of shunt access 32 is.

Fig. 8 represents that in last hurdle side the dry wind temperature is with corresponding air quantity characteristic and in the hurdle side represents that 2 hurdles of the aperture of shunt access 32 constitute down, expression is corresponding to the characteristic variations of dry operating progress, at this, it is following for example to be with the concrete process of the dry operating of standard stroke that typical case is illustrated in.

At first in dry operating, can carry out situation corresponding to it and divide into three processes following three kinds of phenomenons particularly from beginning.That is, can divide into during the constant speed that dry operating begins between originally period of heating, exsiccation (desiccation) carries out especially actively and between dry carrying out and the basic conduct that finishes that the dehumidifies deceleration period during ultimate.

Be equivalent between the period of heating following during: at initial time, for example external air temperature equates with temperature in the water jacket 2, rise to predetermined temperature from external air temperature by producing the dry wind that is heated with heater 23, making sharp based on the resulting dry wind temperature of temperature sensor 41 (with reference to Fig. 6) that is installed in the sag pipe 51.

Some dry wind-warm syndrome degree reach aforementioned predetermined temperature, then become during the constant speed, and the dramatic temperature of dry wind raises and stops and presenting temperature characterisitic near the stable state of flat condition.The heat of dry wind is mainly used in the temperature rising of washings and the evaporation latent heat of the interior moisture of washings, and during constant speed, the desiccation of washings such as clothing is carried out the most actively.

The dry wind that has balancedly carried out heat exchange action for the moisture that is contained in clothing etc. along with further continue to be heated, drying effect progress and break away from temperature constant state and between deceleration period, change.

Though between deceleration period, control device 7 stops to heater 23 energisings, but further promote the drying of clothing etc. by the preheating of dry wind, then, follow to be recycled and be supplied in water jacket 2 and make clothing etc. be cooled in the air-supply (cold wind) of the reduction of dry wind temperature, soon the driving of air-supply arrangement 22 also stops and making the circulation of dry wind stop, and whole dry operating times finish when finishing between deceleration period.

Next, about making the variable dry operating of aperture of shunt access 32 8 describe with reference to FIG. corresponding to the dry wind temperature that in above-mentioned peripheral passage 3, circulates.

During heating,, make shunt access 32 open to greatest extent at dry operating initial stage (among Fig. 8, with during J and the differentiation shown).That is, make the aperture of shunt access 32 become 100% ground, the rotating shaft 62a (with reference to Fig. 6) of 7 pairs of aforementioned stepping motors of control device (not shown) rotates control.The energising of air-supply arrangement 22 and heater 23 (with reference to Fig. 3) also began simultaneously when dry operating began.

Because the aperture of shunt access 32 is 100%, so the dry wind air quantity through shunt access 32 becomes maximum, with respect to this because become minimum, so can make dry wind air quantity that the what is called that water cooled off by being supplied in heat exchanger 31 can heat exchange for minimum through the dry wind air quantity result of over-heat-exchanger 31 paths.

The water spittle that this formation can suppress in the heat exchanger 31 is kicked up phenomenon in a large number and can be alleviated the fan resistance that is caused by the water spittle, and the dry wind through peripheral passage 3, heater 23 etc. is passed through swimmingly, can increase air quantity.

According to above explanation, can efficiently be increased to predetermined temperature in short time because begin the dry wind temperature that external air temperature originally equates substantially with dry operating, the dry operating time can be shortened and the raising of the drying efficiency of washings such as clothing can be sought, and can fully guarantee in peripheral passage 3 dry wind of circulation, so can further help the raising of the drying efficiency of clothing etc.

Also have, the dry wind temperature can be measured by the temperature sensor 41 that is installed on sag pipe 51.As be shown in Fig. 8 ground, if the dry wind temperature reaches predetermined temperature, then the rotating shaft 62a of 7 pairs of aforementioned stepping motors of control device rotates control, makes the aperture of shunt access 32 reduce gradually until becoming minimum (to the direction of closure).

Heated dry wind is used for the drying of clothing etc., the dry wind that comprises moisture flows to heat exchanger 31 paths gradually, and if the aperture of shunt access 32 becomes minimum (for example 30% degree), then flow to the dry wind maximum heat exchanger 31 paths, can seek the further raising of dry wind dehumidification rate.

The dry wind of circulation heats by heater 23 and makes the dry wind temperature further raise in peripheral passage 3, changes into during the constant speed of the predetermined temperature of having stablized.

During whole dry operating, not making the aperture of shunt access 32 is 0%, during dry operating, the dry wind that circulates total some flow to shunt access 32, can keep its effect (guaranteeing and increase etc. of air quantity).

Thus, the dry wind air quantity of heat exchanger 31 paths that can suppress to flow through can suppress the unusual phenomenon of kicking up, the anti-sealing spittle arrives the air-supply arrangement 22 in downstream and guarantees electric security.

At this moment, even the water spittle of kicking up is stranded in heat exchanger 31 path tops and becomes fan resistance, also can not carry out heat exchange (dehumidifying) by replenishing from the ventilation of shunt access 32 air quantity as dry wind, air quantity integral body as the dry wind that circulates does not reduce air quantity, the circulation of the dry wind air quantity of abundance can be supplied in the water jacket 2, thereby the drying efficiency of clothing etc. can improve.

Also have, the aperture minimum of a value that also can make shunt access 32 is 0% to carry out variable adjustment.When the aperture of shunt access 32 was 0%, the whole dry winds that flow to heat exchange unit 61 all flow to heat exchanger 31 paths, can make dry wind all carry out heat exchange and improved dehumidification rate.

During constant speed, dry wind stops that rapid temperature raises and the stable temperature characterisitic that presents the degree that little by little rises, and the desiccation of clothing etc. is carried out the most actively.Because during this constant speed, also make the aperture of shunt access 32 be maintained minimum, become maximum so flow to the dry wind air quantity of the path of heat exchanger 31, the dehumidification rate of heat exchanger 31 becomes maximum, and drying efficiency also raises.

If heat drying further carries out, the drying progress of clothing etc., then finish during the constant speed, change between deceleration period.Between deceleration period, the desiccation of clothing etc. is made progress rapidly and is become the condition of high temperature, the temperature that is used in dry dry wind (discharge wind) sharply rises, and the rising rapidly by 41 pairs of these temperature of temperature sensor detects, and control device 7 stops the energising of heater 23.

Even if heater 23 is stopped, the dry wind temperature also raises for the time being owing to inertia.Between deceleration period, the rotating shaft 62a of 7 pairs of stepping motors of control device rotates control, makes the aperture of shunt access 32 become gradually greatly until reaching 100%.During this period, dry wind further impels the washings drying by preheat temperature.

It is big that the aperture of shunt access 32 further becomes, and is accompanied by the increase of the dry wind air quantity that flows to shunt access 32 and the dry wind air quantity that flows to heat exchanger 31 paths reduces.Therefore, reduced, replenish with air quantity on the contrary, the dry wind air quantity of circulation in peripheral passage 3 is reduced from shunt access 32 circulations by the air quantity of heat exchange.

Thus, because stop the energising of heater 23, so lower gradually as being shown in Fig. 8 ground dry wind temperature.If the aperture of shunt access 32 becomes 100%, the dry wind of maximum flows to shunt access 32, then chilled dry wind (cold wind) circulates in large quantities and is supplied in water jacket 2, still clothing that is in hot state etc. is cooled hastily, soon the driving of air-supply arrangement 22 also stops and the circulation of dry wind stops, and finishes between deceleration period and all the dry operating time finishes.

As above-mentioned ground, by temperature corresponding to the dry wind of circulation in peripheral passage 3, make the aperture of shunt access 32 suitably variable, can guarantee sufficient dry wind air quantity as required, perhaps can adjust the desirability of heat exchange (dehumidifying) as required etc., can make dryings such as clothing efficiently, the dry operating time is shortened.

Next, about corresponding in peripheral passage 3 circulation dry wind air quantity and the variable dry operating of aperture of shunt access 32 is described with reference to Fig. 9.

Fig. 9 compares for example standard stroke and dormancy stroke (the selected stroke of time period that the noise of the medium generation of dry operating is suppressed in desires such as nights) and illustrates, will follow in the characteristic of the dry wind of the carrying out of dry operating and the aperture variation separately of shunt access 32 and be shown the performance plot on 2 hurdles up and down.

As be shown in Fig. 9 ground, and in whole dry operating times, comparing with the standard stroke and the dormancy stroke is controlled to be by control device 7, the fan revolution speed of the fan motor 22b of air-supply arrangement 22 (with reference to Fig. 3) diminishes.Therefore, the dormancy stroke is than the standard stroke, and the air quantity of the dry wind of circulation tails off in peripheral passage 3, though the noise that produces in the dry operating is suppressed, the dry wind air quantity that is used for the drying of clothing etc. certainly also tails off.

So, be controlled to be in the dormancy stroke than the standard stroke, by all making the aperture of shunt access 32 become big in whole dry operating times, make the dry wind air quantity that flows to shunt access 32 become many, the dry wind air quantity that flows to shunt access 32 when making it become with the choice criteria stroke about equally.

According to upper type, can access following action effect.

As dormancy stroke ground, under the few situation of the air quantity of the dry wind of circulation in peripheral passage 3, become big by the aperture that makes shunt access 32, can the dry wind air quantity that flow to shunt access 32 be increased in whole dry operating times, air quantity though flow through in the heat exchanger 31 reduces a little, is replenished from the air quantity that shunt access 32 flows to the dry wind of the peripheral passage 3 of waiting in the blower-casting 22a not carry out heat exchange ground.

Thereby air quantity can not subtract greatly by air quantity as a whole, and the result can suppress the minimizing of the dry required dry wind air quantity of clothing etc.And, because the air quantity of the dry wind of heat exchanger 31 paths of flowing through is suppressed, arrive this situation of air-supply arrangement in downstream so can prevent the heat exchanger 31 interior water spittle from kicking up singularly, can guarantee electric security.

Also have, also can be set at long-time as required the duration of runs of this dormancy stroke than the standard stroke.

Next, about corresponding to the output of the water that is supplied in heat exchanger 31 and the variable dry operating of aperture of shunt access 32 is described with reference to Fig. 8 and Figure 10.

The Action Specification figure of the dry wind air quantity of Figure 10 path that flows to heat exchanger 31 that to be expression compare by the difference of the water yield that is supplied in heat exchanger 31 and shunt access 32 and the aperture of shunt access 32.

The water yield that is supplied in heat exchanger 31 is provided with the influence of the water supply pipe hydraulic pressure in scrubbing-and-drying unit 1 place.The water yield is little if this water supply pipe hydraulic pressure is low, if hydraulic pressure height then the water yield is big.As stating ground, the output when with flowmeter 29a washing being turned round is measured and is finished, and its judgment standard can intactly be used.For example, differentiation is 3 ranks (the little water yield, the standard water yield, big yields), is stored in control device 7, as control followingly.

Under the current water yield that is supplied in heat exchanger 31 was differentiated situation for " the little water yield ", between the period of heating that is shown in Figure 10 (and with reference to Fig. 8) and between deceleration period, the aperture of shunt access 32 was controlled to be the aperture " little " that situation is little than " the standard water yield ".Therefore, the dry wind air quantity of shunt access 32 also tails off than the standard under " the standard water yield " situation.Like this, the water spittle of kicking up in heat exchanger 31 scarcely can become and is detained and becomes the degree of the fan resistance of dry wind, even a large amount of dry winds flow to the path of heat exchanger 31, the air quantity of the volume drying wind of circulation does not reduce yet in peripheral passage 3, can further improve the dehumidification rate of heat exchanger 31.

On the other hand, under the water yield of injecting heat exchanger 31 was differentiated for the situation of " big yield ", the aperture of shunt access 32 was controlled to be than big " greatly " of standard under " the standard water yield " situation.Therefore, the dry wind air quantity of shunt access 32 also becomes more than the standard under " the standard water yield " situation.

That is,, improve dehumidification rate so can carry out heat exchange by big air quantity because the water yield of injecting in the heat exchanger 31 also increases.But, increase air quantity requiredly the water spittle is kicked up in a large number if exceed, temporary transient delay of the water spittle and become the resistance of air-supply, and then might cause the unusual condition that enters air-supply arrangement 22 sides.

Therefore, make shunt access 32 apertures " greatly " and can not only make heat exchanger 31 passage side and also make shunt access 32 sides air quantity to greatest extent in large quantities the air-supply, avoid the water spittle to enter thus to air-supply arrangement 22 sides, and the integral body of seeking the dry wind air quantity increases, and can expect the raising of the drying efficiency of clothing etc.

Also have, the aperture " little " in this so-called shunt access 32 for example is meant in the present embodiment, and the aperture of shunt access 32 is controlled to be, and the aperture of shunt access 32 is 0.8 times of shunting aperture under " standard " situation; The aperture " greatly " of so-called shunt access 32 is meant that the aperture of shunt access 32 is controlled to be, and the aperture of shunt access 32 is 1.2 times of aperture of the shunt access 32 under " standard " situation.

Be shown in initial stage between the period of heating of Fig. 8 during in this part of J, be which kind of situation of " the little water yield ", " the standard water yield ", " big yield " no matter inject the water yield of heat exchanger 31, the aperture that is shown in the shunt access 32 of Figure 10 all preferentially is controlled to be 100%.This is because as above-mentioned ground, at the dry operating initial stage, clothings etc. still were in low-temperature condition originally in water jacket 2 and/or in the peripheral passage 3 etc., compared so whole air quantity increases with dry wind is cooled off with heat exchanger 31, helped the raising of drying property more.

During being shown in the constant speed of Figure 10 (with reference to Fig. 8), no matter be supplied in the water yield of heat exchanger 31 is " the little water yield ", " the standard water yield ", which kind of situation that reaches " big yield ", the aperture of shunt access 32 all is " minimum " that is shown in Fig. 8, and shunt access 32 dry wind air quantity also become " minimum ".

During the constant speed because be promote most clothing etc. drying during, institute is so that the path of the dry wind of maximum by heat exchanger 31 makes the dehumidification rate raising.Also have, having the duty of following in the carrying out of the dry operating that is shown in Fig. 8 as clothesdrier is to be common item between the period of heating, during the constant speed, between deceleration period.

(the 4th embodiment)

Figure 11 is the figure suitable with Fig. 1 of expression the 4th embodiment of the present invention.The 4th embodiment is because similar with the 3rd embodiment, so followingly compare with the 3rd embodiment (with reference to Fig. 6) and illustrate.

Especially be characterized as: the dry wind that is communicated in heat exchange unit 71 and heat exchanger 31 in short circuit exports short circuit path 52 39 sides, that be formed at sag pipe 51, catch 72 (short circuit amount changing cell) is set, the aperture area (passage sections is long-pending) of short circuit path 52 can be changed, below describe in detail.

As be shown in Figure 11 ground, in the lower end of short circuit path 52, inject the rotating shaft 72a of the stepping motor (not shown) that passes through control device 7 (with reference to Fig. 2) institute drive controlling from heat exchange unit 71 outsides (diagram rear side).

The identical shaped square plate body of peristome that is shaped as basic and short circuit path 52 of catch 72, one side catch 72 be mounted on rotating shaft 72a, catch 72 is that rotate at the center with rotating shaft 72a.Rotate by catch 72, short circuit path 52 can be opened and closed, the aperture area (aperture of short circuit path 52) of short circuit path 52 can be changed.

Catch 72 stops up under the state of peristome of short circuit path 52 fully, short circuit path 52 full cut-offs, is that the aperture of short circuit path 52 becomes 0%.Under the state of catch 72 contact inclined wall 30b, short circuit path 52 standard-sized sheets, be that the aperture of short circuit path 52 becomes 100%.

Control device 7 carries out drive controlling to each aforementioned stepping motor, makes catch 62 and catch 72 rotate in linkage.Promptly become following formation: be controlled to be and make that the aperture of aperture and short circuit path 52 of shunt access 32 is always identical and link.Particularly, the aperture of short circuit path 52 is 100% when the aperture of shunt access 32 is 100%, and the aperture of short circuit path 52 is 0% when the aperture of shunt access 32 is 0%.

Next also with reference to Fig. 8, about the effect of the scrubbing-and-drying unit in the present embodiment 1, effect and illustrate.

Dry operating in Fig. 8 begins the initial stage (among Fig. 8, with during the part represented of J), and drive controlling is: make that the aperture of shunt access 32 is 100%, make the aperture that links in the short circuit path 52 of the aperture of shunt access 32 also become 100%.Therefore, become maximum through the dry wind air quantity of shunt access 32 and short circuit path 52, become minimum this moment through the dry wind air quantity of over-heat-exchanger 31 paths, and it is minimum can making the water-cooled dry wind air quantity by being supplied in heat exchanger 31.

And, the phenomenon of being detained takes place and can suppress fan resistance because can reduce the water spittle of kicking up in heat exchanger 31, so the dry wind air quantity through peripheral passage 3, heater 23 etc. is increased.

According to upper type, begin the dry wind temperature that extraneous gas temperature originally equates substantially with dry operating and can efficiently be increased to predetermined temperature in short time, the dry operating time can be shortened and the raising of drying efficiencies such as clothing can be sought, and because can fully guarantee the dry wind of circulation in peripheral passage 3, so help the raising of washings drying efficiency more.

During heating (with reference to Fig. 8), some dry wind-warm syndrome degree reach predetermined temperature, and then the limit is linked catch 62 and catch 72 mutually, and the limit makes the aperture of shunt access 32 and short circuit path 52 equally be decreased to minimum mutually gradually.

Dry wind through shunt access 32 and short circuit path 52 reduces gradually, and the dry wind that flows to heat exchanger 31 paths increases gradually.By being provided with catch 72 in short circuit path 52, from short circuit path 52 short circuits flow to the dry wind outlet 39 of heat exchange unit 71 dry wind also flow to the path of heat exchanger 31 gradually, because the flow of the dry wind that flows to heat exchanger 31 paths is increased, so can seek the raising of the dehumidification rate of heat exchanger 31.

During constant speed (with reference to Fig. 8), the aperture of shunt access 32 and short circuit path 52 is maintained minimum.During constant speed, also by being provided with catch 72 in short circuit path 52, make the dry wind that flows to heat exchange unit 71 from short circuit path 52 short circuits ground export the path that 39 dry wind also flows to heat exchanger 31, because the flow of the dry wind that flows to heat exchanger 31 paths is increased, so can seek the raising of heat exchanger 31 dehumidification rates.

Between deceleration period (with reference to Fig. 8), the aperture of shunt access 32 and short circuit path 52 increases to gradually and arrives 100%.Therefore, flow to the path of heat exchanger 31 and dry wind after being used for exsiccation flows to shunt access 32 and the short circuit path 52 that is not used in exsiccation with increasing gradually.

Therebetween, dry wind further promotes the desiccation of clothing etc. by preheat temperature.Thereby along with the aperture of shunt access 32 and short circuit path 52 becomes big, the dry wind air quantity that flows to heat exchanger 31 paths reduces naturally.Therefore, can suitably reduce the water spittle of in heat exchanger 31, kicking up and avoid becoming fan resistance, and the volume drying wind of circulation in peripheral passage 3 is increased.

After heater 23 stops energising, with the 1st embodiment etc. similarly the dry wind temperature reduce gradually as being shown in Fig. 8 ground.But the aperture of shunt access 32 and short circuit path 52 is 100% and the dry wind of maximum flows to shunt access 32 and short circuit path 52 in the present embodiment.

Therefore, chilled dry wind (cold wind) circulates in large quantities and is supplied in water jacket 2 and makes cooling hastily such as clothing, and the driving of air-supply arrangement 22 soon also stops and making the circulation of dry wind stop, and finishes between deceleration period and all the dry operating time finishes.

As above-mentioned ground, it is variable in the aperture ground of shunt access 32 to link by the aperture that makes short circuit path 52, from short circuit path 52 short circuits flow to the dry wind outlet 39 of heat exchange unit 71 dry wind also be used for the increase of air circulation rightly corresponding to needs, help the raising of heat exchanger 31 dehumidification rates.Therefore, can make clothing etc. dry efficiently, can shorten the dry operating time.

In whole dry operating, not making the aperture of short circuit path 52 in the present embodiment is 0%, the dry wind that in dry operating, circulates total some export 39 from the dry wind that short circuit path 52 short circuits ground flows to heat exchange unit 71.

Thus, with the situation of shunt access 32 similarly, the dry wind air quantity of heat exchanger 31 paths that can suppress to flow through can prevent that the water spittle of kicking up from arriving at the anomaly of the air-supply arrangement 22 in downstream.

Perhaps,, the water spittle of kicking up becomes the fan resistance of heat exchanger 31 paths even being detained vaporificly, also because the air quantity that flows to the dry wind in the blower-casting 22a from short circuit path 52 by heat exchanger 31 and shunt access 32 are carried out short circuit replenishes, so the air quantity integral body as the dry wind that circulates not only can not subtract greatly by air quantity, sufficient dry wind air quantity circulation water jacket 2 can be supplied on the contrary, thereby the raising of drying efficiency can be sought.

Also have, also aperture, for example minimum of a value of short circuit path 52 can be set at 0%.In addition, when the aperture that makes short circuit path 52 is 0%,, flow to heat exchanger 31 paths, can improve the dehumidification rate of dry wind so flow to whole dry winds of sag pipe 51 because the aperture of shunt access 32 also becomes 0% in linkage.

Also have, the present invention is defined in above-mentioned and is shown in each embodiment of accompanying drawing, for example be not limited to have the drum-type washing drying machine of washing function, can be applied to have at least the clothesdrier of functions/drying, though thereby be disposed at as the agitating unit of the clothing in the dry operating etc. and effectively as the cylinder in the water jacket of hothouse, but also can replace it and constitute, for example under static state clothing etc. be hung twelve Earthly Branches and be held in the hothouse.

In addition, though in the scrubbing-and-drying unit in the above-described embodiment, the example that heat exchange unit and sag pipe form as one is shown, be not limited to this, heat exchange unit and sag pipe also can form independently of one another.In addition, when implementing, can in the scope that does not break away from main idea of the present invention, carry out various changes and implement.
