In the rolling washing dryer 1 with said structure, the front of washing machine shell 2 is provided with the selectively actuatable mode, set the operation display unit of time etc. of each operation.Be imported into the not shown control module from the selection instruction of operation display unit input, the operation of each parts controlled, implement from washing to a succession of operation of drying or only carrying out the drying operation by control module.The user can carry out this freely selecting.
During laundry, open gate 8 earlier and in swing roller 5, drop into washings, from operation display unit input instruction, start-up operation.After laundry operations begins, at first in steel ladle 3, add entry and washing agent, drive swing roller 5 rotations, begin to carry out washing procedure by drum driven motor 4 from not shown supply channel.Swing roller 5 is constantly carried the washing operation of throwing from the top to the top, again that beats earlier by 7 pairs of washings of a plurality of agitators on the wall that sets within it, and carries out washing procedure.After the washing procedure, also will carry out rinsing process and dehydration procedure, laundry processes just finishes.When having selected/having imported the mode of operation of the complete procedure of continuous enforcement from washing procedure to the drying operation, washing finishes the back control module and just enters into the drying operation.In addition, when a clothing to humidity carries out drying, can only carry out the drying operation.
In the drying operation, in swing roller 5, pack into earlier through the washings of dehydration or wet clothes (below be generically and collectively referred to as clothing), carry out the drying operation then.In the drying operation, swing roller 5 stirs clothing to rotate with the corresponding rotating speed of drying operation.Meanwhile, heat pump unit 20 and Air Blast fan 15 are driven, and make the drying air begin to circulate.In such drying operation, steel ladle 3 play with clothesdrier in the identical effect in drying chamber.
As shown in Figure 2, heat pump unit 20 compresses by 27 pairs of cold-producing mediums of compressor, and under the effect of its pressure, cold-producing medium flows into refrigerant tubing 41 from compressor 27, circulates in radiator 29, throttling unit 42, heat dump 28, compressor 27.When the heat of compressed cold-producing medium flows in the radiator 29, to the refrigerant tubing 41 that is arranged in the radiator 29 on the contacted air of fin carry out heat release, thereby the air of sending here is heated, form and add hot-air.Add hot-air and in air inlet 11 is delivered to swing roller 5, from the clothing that is being stirred, capture moisture again, become the moisture absorption air, and then discharge from exhaust outlet 12 from the air draft space through exhaust connection 33, heating air blast pipeline 13.
Along with clothing becomes dry gradually, can produce line bits such as the end of a thread, cloth bits from clothing, these line bits are deposited in Air Blast fan 15 and air supply duct place, can cause air-supply to descend.In order to prevent such situation, be provided with in the above-mentioned rolling washing dryer 1 by the integrated filter unit that forms 60 of a plurality of filters that comprises the line bits filter 61 that the back will be mentioned.The moisture absorption air of discharging from exhaust outlet 12 is introduced into the filter unit 60, considers line entrained in the moisture absorption air to be worth doing in addition catching by line bits filter 61, sends into then in the moisture absorption air air supply duct 14.The moisture absorption air of delivering to moisture absorption air air supply duct 14 passes air-breathing tube connector 32, moisture absorption air air intake duct 30, enters the breathing space of heat pump unit 20; When flowing through the heat dump 28 that the cold-producing medium that becomes low pressure through throttling arrangement 42 decompression flows therein, airborne sensible heat of moisture absorption and latent heat are seized and are dehumidified; The condensing drip that produces because of dehumidifying is in water storage portion 34, and the dry air after the dehumidifying enters into radiator 29, and is heated once more, forms air circulation.Not shown draining pump turned round once every the regular hour, and the water that water storage portion 34 is stored is discharged in the steel ladle 3; During draining pump 19 work, be discharged to the outside from water discharge outlet by drainage pipeline 25 again.
In the above-mentioned radiator 29 to air carry out heating heat almost equal electric energy that compressor 27 consumes with by the heat sum of heat dump 28 from the moisture absorption absorption of air, surpass the output that is input to the electric energy in the compressor 27 so radiator 29 can produce, air is heated.But the air within air circulation duct circulates repeatedly, and the heat that whole air are contained will constantly increase with the difference after the heat that deducts the nature heat release from the electric energy that is equivalent to compressor 27 consumption.Simultaneously, the heat that the cold-producing medium in the heat pump cycle is put aside also constantly increases, and it is too high that the temperature of cold-producing medium and pressure just may become, and causes compressor 27 overloads.Occur for fear of such situation, as shown in Figure 2, be provided with in the filter unit 60: the discharge filter 62 that is connected with the air outlet 46 that a part of circulating air in the air circulation duct is discharged; With the air-breathing filter 63 that is connected with the air introducing port 47 that extraneous air is imported within the air circulation duct.
In heat pump unit 20, the temperature of cold-producing medium mobile in refrigerant tubing 41 is monitored.If the temperature of cold-producing medium has met or exceeded the temperature of regulation, then open the inlet valve 74 that is arranged on described air introducing port 47 places, extraneous air is directed within the air circulation duct from air introducing port 47.Owing to be provided with Air Blast fan 15 in the downstream of air introducing port 47 side, extraneous air can flow into the air circulation duct from air introducing port 47 under consequent suction function.Along with the importing of extraneous air, the moisture absorption air in the air circulation duct can be discharged to the outside from air outlet 46.By in air circulation duct, importing extraneous air and the part air being discharged, when flowing to air circulation duct, extraneous air can produce cooling effect, high temperature air can be discharged again, the temperature of circulating air can reduce, therefore, the temperature of cold-producing medium also will descend, and the state of compressor 27 overloads can be prevented.When the temperature of cold-producing medium drops to set point of temperature, inlet valve 74 cuts out, stop to import extraneous air from air introducing port 47, like this, carrying out exhaust from air outlet 46 also will stop, heat just is stored in the air of sending in the air circulation duct, thereby can carry out the high air circulation of drying effect.In addition, as air bleeding valve 48 is set on air outlet 46, can regulate capacity then better.
By carrying out above-mentioned control, heat pump unit 20 just can be with the state work of the best, too high and take to make situations such as measure such as compressor 27 interrupter duties, the heating efficiency that causes thus descend, the drying time is elongated also can avoid with regard to need not like this for fear of the temperature of cold-producing medium.In addition, because air outlet 46 discharges is to pass steel ladle 3, the drying thing be have ever made the moisture absorption air of contribution, so energy loss is less; And the extraneous air that imports from the outside also can mix with the wind pushing air from steel ladle 3, and therefore, it is very little that air discharge and extraneous air import the influence that the drying effect is produced, and the drying time can not increase yet.
The filter unit 60 that is connected with above-mentioned air outlet 46 is provided with discharge filter 62, the line that air contained bits in the air circulation duct is unlikely disperses to the outside.In addition, and also be provided with air-breathing filter 63 on the filter unit 60 that air introducing port 47 is connected, the dust that makes in the extraneous air to be contained is unlikely and invades in the air circulation duct.The concrete structure of this filter unit 60 as shown in Figure 3, wherein, discharge filter 62, air-breathing filter 63 and line bits filter 61 are configured to an integral body.
As shown in Fig. 3 (a), filter unit 60 can take out/push from the face side of washing machine shell 2, when after the washing machine face side is inserted/installed, its significant points is connected with the opening portion of not shown pipeline, so that be connected with air supply duct respectively.The bottom surface that the side is provided with the filter housings 66 of discharge filter 62 is provided with opening portion, this bottom surface opening is connected with the air supply duct of the air that exhaust outlet 12 from steel ladle 3 flows out, and flows into for the moisture absorption air that flows out from steel ladle 3 and has been the filter housing 66.Such moisture absorption air flow into again in the line bits filter 61 by air inflow aperture 65.The air outlet 46 that is connected with discharge filter 62 is positioned at out the downstream of the exhaust outlet 12 on steel ladle 3, and be positioned at the upstream side of line bits filter 61, even, also can guarantee stably to carry out exhaust from air outlet 46 so line bits filter 61 stops up, causes the air capacity that flows through air circulation duct to descend.
The structure of line bits filter 61 is, top filter 61b is entrenched on the lower filter 61a can open the mode that can close by hinge arrangement portion 67, forms the pocket filter that the downside to the air supply direction of air supply duct bloats.That is to say, the air that enters from air inflow aperture 65 is divided into two-layer up and down, screen pack 64 on passing the peristome that covers lower filter 61a respectively and covering after the screen pack 64 on the peristome of top filter 61b, be divided into bilevel air and merge together again, flow to downstream one side.When passing screen pack 64, the line bits that contained in the air are captured/collect.
In addition, line bits filter 61 is chimeric and formed pocket filter by lower filter 61a and top filter 61b, so the capture effect height of line bits, the area of filter is also big, can capture effect by long term maintenance line bits.When covering top filter 61b on the lower filter 61a, shown in Fig. 3 (b), in will embedding engagement groove part 69 on the top filter 61b into towards the edge of opening portion 68 of the top opening of bottom filter 61a, thereby can obtain airtight fastening state.Because line is considered online bits filter 61 places to be worth doing and can be piled up at leisure, therefore be necessary to remove termly the line bits of piling up.When removing the line bits, filter unit 60 is drawn out to the outside, open top filter 61b after, just be easy to get rid of the line bits that are deposited in pocket filter inside.Top filter 61b is covered after on the lower filter 61a, the snap fit tabs thing 71 that is located on its position, top can snap onto in the engaging depression position 72 of the top that is located at air inflow aperture 65, and realize locking, therefore, the vibration that filter unit 60 produces when being drawn out to the outside can not held top filter 61b shake with impact, the situation that the line bits inside can not occurring being deposited in disperse everywhere.
When cleaning/getting rid of the line bits of piling up in hope, only need finger is stretched in the open shape depressed part 73 that is located on the filter housings 66, with position, the top pull-up of top filter 61b.Like this, the fastening state at snap fit tabs 71 and engaging depression position 72 will be removed, and top filter 61b will open from lower filter 61a, become the deployed condition as shown in Fig. 3 (b).
In addition, because the discharge filter 62 of side that is located at filter housings 66 is towards the lateral openings of the flow direction of wind pushing air, even the air outlet 46 that therefore is connected with this discharge filter 62 is deflated valve 48 and opens, the air that is admitted in the air circulation duct can all not discharged yet.The opening diameter by air outlet 46 suitably is set and the ventilation section of air bleeding valve 48 are long-pending, can only the portion of air in the air circulation duct be discharged to the outside.When air was discharged, the line bits that contained in the air were captured by discharge filter 62, thereby can prevent the problem that the principal vertical line bits produce when being discharged to the outside.
In addition, because air-breathing filter 63 is set at air-flow one side of passing line bits filter 61, therefore, when the portion of air in the air circulation duct by when air outlet 46 is discharged, extraneous air can flow into from air introducing port 47, and pass air-breathing filter 63 inflow air circulation duct, to replenish the vacancy that wherein occurs.At this moment, consider the obstruction that the air-flow in the air circulation duct of filter 61 causes the extraneous air that imports to air circulation duct to be worth doing, be provided with dividing plate 70 between air-breathing filter 63 and the line bits filter 61 in order to suppress to pass line.In addition, as shown in Figure 2, because the position of air introducing port 47 is arranged on the upstream side of Air Blast fan 15 and is being close to Air Blast fan 15, be on the bigger position of negative pressure that Air Blast fan 15 produces, so the extraneous air of q.s can be imported in the air circulation duct.
In addition, as previously described, air bleeding valve 48 is set also preferably on the air outlet 46, by and inlet valve 74 between mutual control can realize with the corresponding control of outer temperature degree.Along with the variation of season and environment, the temperature that the place is set of rolling washing dryer 1 also can change, so need carry out and the corresponding control of environment temperature.When natural thermal discharge lower when environment temperature, air circulation duct is big, in order to reduce air-breathing and capacity, can carry out following control, promptly, reduce the aperture of inlet valve 74 and air bleeding valve 48, thereby suppress extraneous air import volume, reduce the thermal discharge of air outlet 46, thereby reduce the import volume of low temperature extraneous air from air introducing port 47.On the other hand, higher when environment temperature, hour from the natural thermal discharge of air circulation duct, in order to increase air-breathing and capacity, can carry out following control, promptly, improve the frequency of opening of inlet valve 74 and air bleeding valve 48, thereby the import volume of increase extraneous air reaches the air discharge rate from air circulation duct.In addition, the aspirating air pipe 75 of opening outside washing machine shell 2 is set preferably on the air introducing port 47, the extraneous air that temperature is lower imports to air circulation duct, thereby can suppress the too high phenomenon of temperature of cold-producing medium.
In filter unit 60 with said structure, because line bits filter 61, discharge filter 62, air-breathing filter 63 have been arranged to one, so, after filter unit 60 pulled out from the front of washing machine shell 2, can take out 3 filters simultaneously, 3 filters are cleaned together.Like this, pretty troublesome cleaning works once can be finished, and safeguards very convenient.In addition, line bits filter 61 not only can improve the line bits and capture performance when the structure pouch, but also the bag shape can be separated into 2 parts, and its inside can be opened, and removes the operation that is deposited in inner line bits like this and just can be easy to implement.
In addition, when being inserted into filter unit 60 in the filter installation room that this filter unit is installed, just can automatically connect with air circulation duct, the pipeline that leads to the pipeline of air outlet 46 and lead to air introducing port 47, the structure of pipe arrangement can carry out simply, filter can be arranged on ventilation, exhaust, the runner separately such as air-breathing.
Though among the embodiment shown in above the inlet valve 74 that only is provided with air introducing port 47 has been shown or the inlet valve 74 of air introducing port has been set simultaneously and the structure of the air bleeding valve 48 of air outlet 46, but, even only be provided with the air bleeding valve 48 of air outlet 46, also can obtain same effect.
Also have, though what illustrate among the top embodiment is that clothes drying device of the present invention is used example in rolling washing dryer,, in vertical clothes washer-dryer and clothesdrier, equally also can use.
Adopt words of the present invention recited above, a kind of like this clothes drying device can be provided, promptly, by means of carrying out exhaust and air-breathing structure to the circulation canal of drying air, can suppress air that the reason heat pump crosses circulates in air circulation duct and causes the heat savings too much and the too high phenomenon of refrigerant temperature that occurs, compressor can not enter overload state, and heat pump can be operated under the best state.Therefore, heat pump can be stablized and generate the drying air expeditiously, shortens the drying time and saves the energy.
