Below, narrate the effect of the washing dryer of above-mentioned structure.
In the washing dryer of above-mentioned structure, (washing and the rinsing) running of when beginning to carry out the running process of standard, at first doing washing.In this laundry running, supply water in tank 2 with feed water valve 63, then, by motor 21 work, swivelling chute 3 alternately rotates to positive and negative two directions with low speed.
When the laundry running is finished, next begin the dehydration running.In this dehydration running, after the water in the tank 2 is discharged, at a high speed swivelling chute 3 is rotated to a direction.Thus, the washings in the swivelling chute 3 is carried out centrifugal dehydration.
When the dehydration running is finished, next carry out dry operating.In this dry operating, as shown in Figure 2, damper 58 is arranged to, and opens the inlet scoop 33 (swivelling chute 3 in ventilation the road 41 and part between the evaporimeter 44) of ventilation shaft 32, and discharge wind path 57 is closed.Under this state, swivelling chute 3 is rotated to positive and negative two directions with low speed, make motor 43 work of circulation simultaneously with pressure fan 36.Like this, under the air-supply effect of blowing fan 42, shown in Fig. 2 arrow, the air in the tank 2 is in the return air duct 34 and connection flexible pipe 35 flow ventilation pipelines 32 of warm braw outlet 10 via ventilation road 41.
And, begin to carry out the work of the compressor 50 of heat pump 52 at this moment.Like this, enclose the state that refrigerant in the heat pump 52 is compressed into High Temperature High Pressure, the refrigerant of this High Temperature High Pressure flows in the condenser 45, carries out heat exchange with air in the ventilation shaft 32.As a result, the air in the ventilation shaft 32 is heated, and the temperature of refrigerant descends and is liquefied on the other hand.Then, this refrigerant that has liquefied gasifies by choke valve 51 and be depressurized back inflow evaporator 44.Thus, the air in 44 pairs of ventilation shafts of evaporimeter 32 cools off.Refrigerant by evaporimeter 44 turns back to compressor 50.
Like this, flow into air in the ventilation shaft 32 in the above-mentioned tank 2 by evaporimeter 44 cooling and dehumidifyings, afterwards by condenser 45 heating by warm brawization.Then, this warm braw is fed in the tank 2 from warm braw inlet 11 via connection flexible pipe 39, steam line 40, and then imports road 28 and be fed in the swivelling chute 3 from warm braw introducing port 17 via warm braw path 26, warm braw.
Supply to warm braw in the swivelling chute 3 behind the moisture of having taken away washings, from above-mentioned warm braw outlet 10 via return air duct 34 and connect in the flexible pipe 35 flow ventilation pipelines 32.
So, circulate between ventilation shaft 32 with evaporimeter 44, condenser 45 and swivelling chute 3 by air, the washings in the swivelling chute 3 is carried out drying.In addition, in this dry operating, be accompanied by as described above to cooling off by the air in the ventilation shaft 32, surface at evaporimeter 44 generates condensation, its dewdrop from evaporimeter 44 drip and along under the inclined plane 32b of ventilation shaft 32 flow down, be discharged to outside the machine via tube connector 56 and water discharge outlet 55 from dehumidifying water outlet 54.
With above relative, when freezed in the space that is provided with washing dryer, as shown in Figure 1, damper 58 is switched to, the inlet scoop 33 (swivelling chute 3 in ventilation the road 41 and part between the evaporimeter 44) of ventilation shaft 32 is closed, discharged wind path 57 and open, under this state, begin to carry out the work of the compressor 50 of heat pump 52, make simultaneously and discharge with pressure fan 59 work.
Like this, shown in solid arrow among Fig. 1, ventilation shaft 32 outer air are inhaled in the ventilation shaft 32 from air introducing port 61, and are cooled by evaporimeter 44.Then, this chilled air is discharged to the place ahead of machine exterior by discharging wind path 57, is freezed in the space that is provided with washing dryer.In addition, at the same time, the air of machine exterior is inhaled in the casing 1 (outside the ventilation shaft 32) from the extraneous air suction inlet 68 of casing 1.
At this moment, shown in Fig. 1 dotted arrow, cooling device 48 water fillings from feed water valve 63 is had to condenser 45 via water injection pipe 62 so water flows in the water service pipe 49 of cooling device 48, make condenser 45 coolings by the water that flows in this water service pipe 49.That is to say, the heat energy that when adopting 44 pairs of air of evaporimeter to cool off, is absorbed and since the work of compressor 50 and additional heat energy be delivered to from condenser 45 the water as the cooling medium, with these heat absorption and heated water is discharged from via tube connector 67 from condenser 45, therefore, condenser 45 can not become unusual high temperature, evaporimeter 44 also correspondingly becomes low temperature, thereby can be effective as refrigeration system (coolingsystem) work, can freeze the space that is provided with washing dryer.
In experiment, the cooling per minute of at this moment condenser 45 is used the water of 1～1.5 liter (liter), in this case can be in about 1 hour be 4m with floor area
2The space cool off about 10 ℃, thereby can determine to be enough to work as cooling device.
In addition, though this moment, condenser 45 was cooled as described above, but suppress air mobile by condenser 45 energetically.But, when dry operating,, be connected with swivelling chute 3 via steam line 40 grades, and then be connected with return air duct 34 from swivelling chute 3 by the wind path of condenser 45, in such structure, wind path is roughly near air-tight state.Therefore, when cooling operation, by inlet scoop 33 (swivelling chute 3 in ventilation the road 41 and part between the evaporimeter 44) being stopped up with damper 58, the wind path of condenser 45 sides is in fact blocked, even thereby between evaporimeter 44 and condenser 45, there is air introducing port 61, in fact can not produce the air flow that flows through condenser 45 yet.Therefore, have and set up a damper 58 and just can add the such effect of refrigerating function.
And, even also can keep open state at dry operating space-time conductance inlet 61.Even this is because as mentioned above all sealings of wind path at place's opening, can not made a big impact to the mobile of air yet.The phenomenon of the liquid of this situation in only offer place's aperture on jar jar under also can spontaneous current is identical.Like this because the part of the formation air introducing port 61 of ventilation shaft 32 is positioned at the wind downside that flow of circulation with the circulated air of pressure fan 36 generations, and become negative pressure herein, therefore can discharge some pressure at this, have the effect that evaporimeter 44 can be easy to dehumidify so on the contrary when dry operating.
In the invention of constructing like this, switch damper (wind path switching device shifter) 58, so that open row goes out wind path 57, and swivelling chute 3 in ventilation road 41 and the part between the evaporimeter 44 are closed, make heat pump 52, discharge pressure fan 59 and cooling device 48 work, like this, water cools off condenser 45, cool off with 44 pairs of air outside the ventilation road 41 that air introducing port 61 imports of evaporimeter, and it is discharged to machine exterior, thereby utilize the desiccant heat pump 52 of washings to freeze to the space that is provided with washing dryer from discharging wind path 57.
By the way, be 4m in for example floor area
2About 10 ℃ of space coolings the time, the ability of compressor 50 needs about 1.2kWh.This be because, though 1m
2Thereby floor area need about 200Wh with above-mentioned 4m
2About area just need about 800Wh, but compressor is different with the air regulator that is arranged on machine exterior, the compressor 50 in Gou Zao the invention is positioned at machine intimate like this, needs himself heat of additional absorbent.If the driving of compressor 50 self is input as 400Wh, then need the refrigerating capacity about 1.2kWh.For the water of per minute with about 1.0 liters discharges this heat, the temperature of water is risen about 17 ℃.Therefore, when the water temperature in summer was 20 ℃ of left and right sides, discharge approximately less than 40 ℃ hot water, just can be freezed.
In this structure, as mentioned above, the warm water that has absorbed heat from condenser 45 is discharged in the tank 2 via tube connector 67.In tank 2, has water discharge outlet 12 in its bottom, outside tank 2, be provided with draining valve 13 on the water discharge outlet 12, and then be connected with scupper hose 14 via this draining valve 13, water in the tank 2 is discharged to machine exterior thus, so, condenser 45 has been carried out cooling and has been discharged to water in the tank 2, be discharged to machine exterior with the path of water discharge outlet 12 → draining valve 13 → scupper hose 14.
When the space that is provided with washing dryer is cooled off, the needed water yield of the cooling of condenser 45 is 1～1.5 liter of per minute as mentioned above, when the water of this tittle and the dewdrop that drips of for example condensing along with being cooled off by 44 pairs of air of evaporimeter converge and when carrying out draining, just need delivery ratio only to discharge the more water of volume of dewdrop.Therefore, just can not steadily successfully carry out draining, spilling water can take place by natural drainage.Like this,, just need temporarily to store the jumbo water storage tank of the water that will discharge, also need the pump of big ability, thereby cost improves if when utilizing pump (pump) to carry out draining.
Relative therewith, the invention of this structure is discharged the used water of the cooling of cooling condenser 45 via tank 2, and this can utilize the hydraulic pressure in the water channel to carry out.Therefore, can under the situation that does not need special structure such as pump and jumbo water storage tank (tank), carry out necessary draining, thereby avoid raising the cost.
And the invention of this structure is that the used water of the cooling of condenser 45 is discharged via tank 2, wherein, by before via tank 2 this water being discharged draining valve 13 cutting out, thereby it can be stayed in the tank 2.Thereby the used water of the cooling of condenser 45 has heated up about 15～25 ℃ from the water temperature of condenser 45 absorption heats than the initial stage.In the invention of this structure, it can be stayed in the tank 2 and be used for doing washing next time, like this, not only cooler condenser 45 used water can not slatterned in vain but with its effective utilization, and thereby the water after the available intensification does washing and improves the laundry performance, made contribution to improving the original performance of washing machine.
By the way, washing machine generally is arranged in the dressing cubicle with the bathroom adjacency more, so the refrigerating function of the invention of this structure is used for the refrigeration of this dressing cubicle more.And the user is many after having a bath generally speaking does washing the washings of taking off, and at this moment, can freeze to dressing cubicle with washing machine, and the used water that should freeze stays in the tank 2, is used in effectively in the laundry after the refrigeration again.
In addition, because water inlet 66 more leans on the top than gap, so when water level surpassed gap, water was discharged from from gap, therefore, the water of staying in the tank 2 can adverse current not arrive in the cooling device 48 (condenser 45).And, replace also and can prevent structure, in case non-return stream in the adverse current that tube connector 67 is provided with check-valves etc.
In addition, in the invention of this structure, the cooling device 48 that water is cooled off condenser 45 is assembled in the condenser 45, relation between them is made as row 46a with respect to the refrigerant runner pipe 46 of two row condensers 45, there are row in the row 49a of the water service pipe 49 of cooling device 48, thus, each row of the water service pipe 49 of cooling device 48 cool off the refrigerant runner pipe 46 of two row respectively via fin 47.Like this, can reduce the columns of water service pipe 49, efficient is the heat of absorptive condenser 45 well.
And, the refrigerant in the refrigerant runner pipe 46 flow with water service pipe 49 in the flowing of water for flowing in opposite directions, become the mobile in opposite directions of heat like this and carry out heat exchange, can further improve heat exchanger effectiveness (cooling effectiveness).
With above relative, Fig. 7 to Fig. 9 represents the second embodiment of the present invention and the 3rd embodiment (the second and the 3rd embodiment), and its identical with first embodiment separately part is added same-sign, and its explanation is omitted, and different parts only is described.
(second embodiment)
In second embodiment shown in Figure 7, has the water storage portion 81 that was arranged in 2 minutes with tank.In detail, bottom in casing 1 is left tank 2 ground and is provided with water storage portion 81, and this water storage portion 81 is that for example vertical view is the water storage tank of コ font, Fig. 7 represents the opposed part 81a of this water storage tank that is the コ font 81, and this part 81a is configured in corner, the left and right sides portion of casing 1 inner bottom part.Therefore, at this moment, the part that connects the opposed part of water storage portion 81 is configured in the front portion of casing 1 inner bottom part.
And the water storage valve 82 that is arranged on the bottom of tank 2 is connected with water storage portion 81 by tube connector 83, therefore, enters water the tank 2 from cooling device 48, is stored into the water storage portion 81 via tube connector 83 from tank 2 by opening water storage valve 82.Be stored in the water in the water storage portion 81, available water level sensor 71 detects by the water level of tank 2, like this, learns that when detection water storage portion 81 is full by the water filling, when the water level of tank 2 rises, closes water storage valve 82.
And, pump 84 is set in water storage portion 81, and the water that storage is stayed in the water storage portion 81 turns back in the tank 2, at this moment by flow pipe (water tube) 85 by pump 84, water storage valve 82 and draining valve 13 all are made as closed condition, water can be stored in the tank 2 thus.When the water level of tank 2 arrives the height (level) of regulation, adjust water level by opening and closing draining valve 13.So the available water of staying in the tank 2 is done washing.
And, after laundry, discharge by opening the water that draining valve 13 can stay storage in the tank 2, like this, in this case, cooler condenser 45 used water are stored into use in the water storage portion 81 that separates with tank 2, discharge from tank 2 then, in other words, cooler condenser 45 used water were stored in the water storage portion 81 that is different from tank 2 before discharging via tank 2.Like this, not only cooler condenser 45 used water can not slatterned in vain and effectively it utilized again, and can cooler condenser 45 used water conservancies be used in the washing and rinsing or the running of laundry repeatedly of doing washing in turning round according to the capacity of water storage portion 81.
(the 3rd embodiment)
In the 3rd embodiment shown in Figure 8, has the water storage portion 91 that partly separates with water storage with the washing rinsing at tank 2.In detail, the part of doing washing of tank 2 is in the inside of tank 2, water storage portion 91 in the outside of tank 2, particularly this moment its underpart mainly be the places, both sides, the two side portions 91a of water storage portion 91 is connected by central portion part 91b.
In addition, be arranged on the bottom of tank 2 water storage valve 82, connect water storage valve 82 and water storage portion 91 tube connector 83, be arranged at water storage portion 91 pump 84, be connected the flow pipe 85 of pump 84 and tank 2, the same with second embodiment, therefore, control with second embodiment the samely.
Like this, in the case, cooler condenser 45 used water were stored on the tank 2 in the water storage portion 91 that partly separates with water storage with the washing rinsing before discharging via tank 2, can obtain the action effect identical with second embodiment.In addition, can be with the water storage portion 91 that stores water as balance weight (counterweight), be suppressed at particularly the vibration of tank 2 when the dehydration running when washing rinsing, thereby help to improve dehydration and vibration.
(the 4th embodiment)
The 4th embodiment shown in Figure 9, the same with the 3rd embodiment, also have the water storage portion 101 that partly separates with water storage with washing (laundry) rinsing at tank 2.But, in this 4th embodiment, be to have water storage portion 101 in the both sides, top of the outside of tank 2, its two side portions 101a is linked by the tube connector 101b at the back that for example is arranged on tank 2.
And then, in water storage portion 101 water injection valve 103 being set, this water injection valve 103 is connected by water injection pipe (hose pipe) 104 with tank 2.Like this, by opening water injection valve 103, can under the situation that needn't use pump, the water that stores in the water storage portion 101 be injected in the tank 2 via water injection pipe 104.
Like this, in the case, cooler condenser 45 used water also were stored in the water storage portion 101 that partly separates with water storage with the washing rinsing on the tank 2 before discharging via tank 2, can not only obtain the action effect identical, and have with the structure that do not need pump advantage with its realization with second embodiment.
In addition, can carry out cooling period to condenser 45, cooler condenser 45 used water are continued to inject tank 2, like this, the water that exceeds predetermined water level is discharged from tank 2 gradually.When freezed in the space that is provided with washing machine, per minute uses about 1～1.5 liter cooling water as mentioned above.Relative therewith, washing when action employed water is about 15～20 liters, thereby when the refrigeration of carrying out about 15～20 minutes, just can obtain its required water yield.Not only to wash with cooling water under the situation that also will use it for rinsing, need only the water that has again about 30 liters, so, carry out just can obtaining about 45 minutes to 60 minutes its required water yield altogether.Can cause waste if the water that produces after it abandons like this, therefore, the draining valve 13 of opening the below comes down in torrents the water that be stored in the tank 2 before go out, and injects new water simultaneously from the top, can store the water of high temperature so always.Wash rinsing by the water that uses this high temperature, can further improve the laundry performance.
And preferably practicing every conceivable frugality is used for water that condenser 45 is cooled off.So preferably the temperature to condenser 45 detects, supply with water to condenser 45 according to this testing result control.The temperature of condenser 45 is detected by temperature sensor 73.Therefore, detect with the temperature of 73 pairs of condensers 45 of temperature sensor, and carry out following control, when testing result is high temperature, cooling water is flow through, in case after the cooling cooling water is stopped.Be under the situation of R410a for example, the central temperature of condenser 45 need be controlled at smaller or equal to 60 ℃ according to the restriction of pressure at refrigerant.Therefore, make flow of cooling water, stop, making the temperature of condenser 45 become about 58 ℃.
Like this, the water-saving result that can obtain expecting.
And then, preferably when dry operating, also condenser 45 is cooled off.Washing dryer carries out the dry operating of washings with heat pump 52, wherein, as mentioned above, dehumidify with 44 pairs of moisture that obtain from washings of evaporimeter, the latent heat that is reclaimed at that time reuses as the energy that heats at 45 pairs of air that flow through herein of condenser.Like this, except heat release loss seldom, dry nearly all be not released and be recovered and recycle with heat.Therefore, compare the dry operating that to carry out good efficiencies with heater formula (heatertype) washing dryer.
In being formed with the heat pump in this loop, 50 works of compressor are converted into heat energy in theory, and the temperature of refrigerant is risen.Therefore, when thermal discharge after a little while, temperature rises heat pump gradually along with the process of time, has the problem above the work possible range of compressor 50.For fear of this problem of generation, effective method is that compressor 50 is cooled off, thereby with cooling fan it is cooled off in air regulator.But, in washing dryer, be provided with in addition and be used for the fan of cooling compressor 50 specially and can cause the maximization of washing dryer, can cause that also cost improves (cost increase).And, also can increase the air-supply noise.
In view of this problem, in the present embodiment, water comes condenser 45 is cooled off when dry operating, replaces with wind compressor 50 being cooled off with this.That is to say that replaced and cooling fan is set comes compressor 50 is carried out air-cooled, and water cools off condenser 45, so also can obtain the same heat with heat pump and be discharged into outside result.Water by for example adopting 1 liter of per minute rises the temperature of this water about 14 ℃, thereby can be with heat recovery.Generally, for the system of heat pump 52, if the cooling of carrying out about hundreds of Wh just can obtain the balance (balance) of energy when dry operating, thus can control fully it, thus can carry out stable dry operating.
And the cooling that water carries out condenser 45 also can be implemented in the later stage of dry operating.In the later stage of dry operating, the temperature inside of swivelling chute 3 becomes about 60 ℃.Reach situation about 80 ℃ to 100 ℃ compared with the temperature inside of swivelling chute 3 when carrying out washings dry with heater (heater), the temperature of this moment be we can say lower, however also is quite high temperature.Therefore, the temperature in swivelling chute 3 becomes the later stage of quite high dry operating, and water cools off condenser 45.Like this, just enter in the swivelling chute 3, can promptly the temperature in the swivelling chute 3 be reduced in device 45 heating that almost is not condensed of evaporimeter 45 cooled airs.The cooling of condenser 45 being carried out about 5 minutes to 10 minutes by for example water, thus the temperature in the swivelling chute 3 can be become smaller or equal to 50 ℃, can make user's imperceptible undue temperature when dried washings is taken out from swivelling chute 3.
The present invention not only be confined to above-mentioned and in the accompanying drawings shown in embodiment, can in the scope that does not break away from purport, carry out suitable change, particularly washing dryer integral body is not limited to above-mentioned transverse axis rotary drum-type, also can be the longitudinal axis rotary drum-type that longitudinal axis shape ground has tank and swivelling chute, or the like.
