At first carry out diagrammatic illustration with reference to the overall structure of Fig. 1,2 pairs of scrubbing-and-drying units.As shown in the figure, the basket 1 that forms the shell of scrubbing-and-drying unit is the structure of rectangular box shape, has the door 2 that opens and closes the washings input port in its front face side, has guidance panel 3 (operation panel) at an upper portion thereof, and side has the bonnet 4 that can load and unload in the back.In this basket 1, be provided with by not shown a plurality of suspensions (suspension) resiliency supported can water storage tank 5, the mode of rotating with the transverse axis that can center on inclination in this tank 5 be provided with the cylinder 6 as swivelling chute, the front face side peristome of these tanks 5 and cylinder 6 all relatively disposes with described door 2, has formed the structure that opens and closes by 2 couples of so-called washings input port 1a of door.
Described cylinder 6 is well-known, has a plurality of aperture 6a on perisporium, in washing operation, dry in service to take in the positive and negative rotation of state low speed of washings S, rotates to a direction in the dehydrating operation high speed in addition.On the other hand, open end in the front face side of tank 5, spread all between itself and the described door 2 watertight be provided with the bellows (bellows) 7 that is rich in flexibility, and bellows 7 also contact with the inner face side elastic force of described door 2, thereby prevents that sealing disperses to the outside from tank 5 etc.In addition, described cylinder 6 is driven by drum driven motor (drumdriving motor) 8 direct (direct) rotation of the DC brushless motor by the external rotor type (the outer rotor type DC brushless motor) formation of the rear side that is arranged on tank 5.
And, be formed with the circulating path 9 of air in the mode of the outside that surrounds described tank 5.This circulating path 9 is made of pipe (duct), and suction inlet 9a is connected and is connected the bottom of tank 5, and the discharge opening 9b of the other end is connected and is connected near the front openings portion of tank 5 and cylinder 6.Therefore the tank 5, the roughly airtight space of quilt that surround atresia have been formed.But, heating arrangements 10 and the circulation wind pushing mechanism 11 that constitutes warm braw unit (warm air unit) is set at the position midway of this circulating path 9, generation is used for the warm braw of washings S such as drying clothes, and can via circulating path 9 this warm braw circulation be supplied in tank 5 and the cylinder 6 shown in the solid arrow A as shown in fig. 1.
And then the upstream side in described warm braw unit is equipped with heat exchange mechanisms 12.This heat exchange mechanisms 12 has the water sprinkler 13 that works as water-cooled mechanism on top, heat exchange function with so-called water-cooled dehumidifying type, become wet air (warm braw) with respect to when drying is moved, helping to carry out drying, make the air cooling, should airborne condensate moisture remove by watering from water sprinkler 13.Then, the dry cold air (air) after the dehumidifying is once more through heating arrangements 10 warm braw unit such as grade and by warm brawization, and provided in tank 5 repeatedly, and so-called warm braw is supplied with in circulation, with washings S drying.
In addition, from the watering of described water sprinkler 13, undertaken to water management by the water-supply valve 14 that is provided in basket 1 internal upper part, the draining valve 15 of the bottom of its draining through being arranged on tank 5 is discharged outside machine with dehumidifying water.In addition, at the upstream side of the wind pushing mechanism 11 of circulating path 9 and be the downstream of water sprinkler 13, be provided with the air entry 16 of opening outside machine.This air entry 16 works as the atmosphere introducing mechanism as described later.As it position is set, is preferably and is driving wind pushing mechanism 11, air circulation time in circulating path 9, thereby become the position that vacuum sucks air outside easily.
On the other hand, described water-supply valve 14, be connected on the water source from the beginning as the outside of water-supply source, form the mode that to switch the so-called three-way switch valve of feedwater by the interior transfer valve of establishing to described water sprinkler 13 and water injecting tank (water fillingcase) 17.Described water injecting tank 17, though do not illustrate, its inner bottom part can be connected in the tank 5 to water flowing.Therefore, running water can feed water in tank 5 through described water-supply valve 14 and water injecting tank 17.In addition, be arranged in the water route of giving of this water injecting tank 17, taken in detergent box (detergent container) 18.This detergent box 18 is positioned at the frontal left of guidance panel 3, is configured to plug from basket 1 front face side with respect to water injecting tank 17.Therefore, by taking in washing agent in advance in this detergent box 18, to tank 5 feedwater the time, thereby this washing agent is driven to tank 5 by current and provides.
Express as Fig. 1,3,, be provided with and connect outer in this tank 5, as to carry out exhaust air output mechanism, the air in the tank 5 can be discharged outside machine with machine on the top, rear of tank 5.This air output mechanism specifically constitutes by constituting to link in the tank 5 with the blast pipe 19 of the exhaust pathway of machine between outward and the air bleeding valve 20 that is provided with for the openend of the front that opens and closes this blast pipe 19.Wherein, blast pipe 19 has crooked and flexible all freely accordion part 19a on its part.On the other hand, air bleeding valve 20 comprises valve body 20a and this valve body 20a is opened and closed valve CD-ROM drive motor (the valve driving motor) 20b by formations such as geared motors (geared motor) that rotates, valve body 20a opens and closes rotation according to the carrying out of operation in predetermined timing (timing).This air bleeding valve 20 is set in the recess 21 on being formed on above the basket 1, is covered with the filter (filter) in the hole with a plurality of grooves (slit) shape in the above.
Next, the effect that has the drum-type washing drying machine of said structure with reference to time diagram explanation shown in Figure 4.
In scrubbing-and-drying unit, at the running (operation course) of selecting established standards thus during beginning (start) operation, such as everyone knows, by not shown control device head roll CD-ROM drive motor 8, respectively move stroke accordingly with washing, rinsing, dehydration, drying etc., the cylinder 6 of taking in washings S is rotated driving based on appropriate speed control.Here, the later operation of dry trip after the washing stroke end shown in Figure 4 is described.
As shown in Figure 4, common by warm braw carry out dry in service, be present in the wind pushing mechanism 11 and heating arrangements 10 work of the circulation usefulness of the formation warm braw unit in the circulating path 9, consequent warm braw circulates in the confined space of tank 5 and circulating path 9.At this moment, thus water-supply valve 14 work feed water to the water sprinkler 13 of heat exchange mechanisms 12, sprinkle water in circulating path 9 from water sprinkler 13.Drum driven motor 8 drives with the rotation of low speed positive and negative alternate ground in addition, the washings S in the mixing drum 6.Like this, by the warm braw that in confined space, circulates along solid arrow A direction with the washings drying in the cylinder 6.Thereby finish warm braw that desiccation contains a large amount of moistures by the dehumidifying that is cooled of the watering from water sprinkler 13, become dry cold air, then through heating arrangements 10 unit such as warm braw such as grade once more by warm brawization, circulation is supplied with in tank 5.
On the other hand, in service in this drying, no power in air bleeding valve 20, so valve body 20a remains closed condition with blast pipe 19, will cut off with the ventilation of outside.Therefore, warm braw can not escape to outside the basket 1.In addition, cut off the energising to heating arrangements 10 before dry end of run, the generation of steam tails off, and be cut off between air in the confined space and the outside simultaneously, thereby its atmosphere temperature is maintained the state than higher temperatures, carries out so-called waste heat drying.In addition, though be positioned at the state that the air entry 16 of the upstream side of wind pushing mechanism 11 is in opening always, the place because the air in the confined space is not overflowed is not so can import outside Cryogenic air from air entry 16.
Drying at washings S carries out, when detecting the aridity that reaches regulation by not shown temperature sensor (temperaturesensor) etc., dry end of run forwards cooling operation stroke shown in Figure 4 to.Owing to also be in the condition of high temperature near the input port 1a such as inner face side of washings S, door 2, the cooling operation is the operation that is used to make its low temperatureization.At this moment, air bleeding valve 20 energisings are opened, and have guaranteed to outside exhaust.At this moment, wind pushing mechanism 11 and drum driven motor 8 are in the state that continues the energising operation.On the contrary, heating arrangements 10 and water sprinkler 13 no powers are in off position.
Therefore, in service in this cooling, under the state of cylinder 6 rotations, agitator treating thing, the air of low temperature circulates in confined space by wind pushing mechanism 11.The air of this low temperature flow with dry the operation time warm braw mobile identical, also circulate along solid arrow A direction.In service in this Cryogenic air air-supply, decrease of temperature is slower, and the atmosphere temperature in the confined space slowly descends.Yet in the present embodiment, entering when operation cooling blast pipe 20 opening action immediately, confined space becomes the state that is communicated with via blast pipe 19 and machine outward.On the other hand, because air entry 16 is in normally open, therefore when the air in tank 5 confined spaces such as grade is discharged by blast pipe 19, import outside ozone from air entry 16.In addition, the air-breathing scavenging action shown in the dotted arrow B is among Fig. 1 and Fig. 3, makes in the process of the air circulation in the confined space in the driving by wind pushing mechanism 11, executes air-breathing scavenging action by air bleeding valve 20 is opened.
And in the present embodiment, the position that the entrance side of blast pipe 19 promptly is connected with tank 5 is configured in the top, rear that the interior pressure-volumes in the tank 5 of circulating air easily raise, so good to the scavenging action of outside exhaust from blast pipe 19.And then air entry 16 also is positioned near the upstream side the wind pushing mechanism 11, so become vacuum state, has promoted getter action.Therefore, from the outside ozone of air entry 16 importings, simultaneously from discharge the still hot air in the tanks 5 as the blast pipe 19 of air output mechanism.This air-breathing scavenging action carries out continuously, atmosphere temperature in the confined space is subjected to the importing of new atmosphere and descends, even can make near the temperature washings S and door 2 inner face side, the input port 1a quickly fall to the temperature that contacts such as hand, arm not have obstruction yet.When reaching set point of temperature by the detected temperature of not shown temperature sensor, this cooling end of run when perhaps having passed through predefined stipulated time.
According to the foregoing description, play following effect.
In service in the cooling of being undertaken by the air-supply of the circulation in the confined space that constitutes by tank 5 and circulating path 9, the air bleeding valve 20 that constitutes the air output mechanism is opened, thereby make it possible to carry out exhaust outside machine, so the air that circulates in described confined space is discharged outside machine from the blast pipe of opening 19.On the other hand, be subjected to this scavenging action, from the air entry 16 new atmosphere that import.Can carry out air-breathing scavenging action energetically based on the circulation air-supply like this, atmosphere temperature quilt in the confined space is low temperatureization promptly, the temperature of the open end side of inner face side, tank 5 and the cylinder 6 of the door 2 of washings input port 1a periphery also descends rapidly, even quickly fall to the temperature that contacts such as hand, arm do not have obstruction yet.
Therefore, when dried washings S is taken out,,,, can operate safely so the user can not frightened because input port 1a is a low-temperature condition even hand, arm touch input port 1a periphery.And, owing to do not rely on the watering cooling of being undertaken by water sprinkler 13,, also can seek the reduction of operating cost so can realize the saving of water resource.In addition, in the present embodiment, because will carrying out the blast pipe 19 of exhaust outside machine, the position, rear of the tank 5 that easily raises from the interior pressure-volume of circulating air draws, so carry out forced exhaust easily.In addition, owing to will import the suction side that the air entry 16 of atmosphere is connected wind pushing mechanism 11, so the suction of atmosphere is also carried out easily.Therefore, can the temperature of washings, input port periphery be descended rapidly with the air-breathing scavenging action of the efficient promotion of simple structure.
In addition, because the air bleeding valve 20 that the blast pipe 19 as the discharge path of air is opened and closed is in service the opening of cooling, and in other operation stroke, the washing operation of for example being undertaken by warm water, the drying operation stroke that undertaken by warm braw etc., it is closed, effectively prevented spilling of heat energy thus, the temperature in the anti-water stopping trough 5 reduces.And then, also effectively having prevented noise to external leaks, can carry out and the corresponding careful open and close controlling of various operation strokes, thus preferred.
Relative with the foregoing description, Fig. 5 represents variation of the present invention.The scrubbing-and-drying unit of this example can further improve the discharge ability of air output mechanism.Below, for part mark same-sign same as the previously described embodiments, and dispense explanation, only different piece is described.
That is, this variation is provided with the wind pushing mechanism 23 that is made of fan (fan) 23a and fans drive motor (fan driving motor) 23b on blast pipe 19.The wind pushing mechanism 23 that is arranged on like this in the blast pipe 19 is the exhaust special use.Other structure is identical with embodiment shown in Figure 3.
In this variation, when the cooling operation, wind pushing mechanism 23 is worked with the opening action of air bleeding valve 20.Air in the confined space is by tank 5 (with reference to Fig. 1), discharge outside machine more energetically through blast pipe 19 thus.Its discharge rate increase as a result, following in this air import volume from suction inlet 16 also increases, so the inner air of heat that is had in the machine is more promptly replaced by the atmosphere of low temperature.Therefore, more promptly with the peripheral cooling of the input port 1a such as inner face side of washings S, door 2.
In addition, the present invention is not limited in top described and embodiment shown in the drawings.For example the atmosphere introducing mechanism is not limited only to the suction side of the wind pushing mechanism in the circulating path, for example also can utilize have with tank in the structure (give water route) that is connected, to the gap of the detergent box periphery in the water injecting tank on the water route.In addition, the air output mechanism is not limited in the structure of directly discharging outside machine, also can discharge in the space in machine.That is, so long as can get final product from confined space exhaust that constitutes by tank, circulating path and the structure that can import atmosphere.In addition, the present invention can implement the back side from tank provides the scrubbing-and-drying unit of type of warm braw, air too, can carry out various changes and implement in the scope that does not break away from purport of the present invention.
