Description
Technical field
The present invention relates to a kind of clothing drying device; Have: drum housing, be received in laundry drum and process air channel in the drum housing; Said process air channel fluid is connected to drum housing, and wherein, autonomous hot reservoir is arranged in the process air channel or on the process air channel.The invention still further relates to a kind of method that is used for drying clothes, wherein, handle air and be conducted through the autonomous hot reservoir that is arranged in the process air channel or on the process air channel.
Background technology
This clothing drying device and this method are based on each open DE3710710A1 and DE10224940A1.
According to DE3710710A1; Clothing is dried in clothing drying device by means of the air flow that in the process air channel of sealing, conducts; Wherein, said clothing drying device is implemented as roller dryer, and air flow was heated before it is applied to clothing; After being applied to clothing, be cooled, go out the moisture that air flow carries with condensation.Process air channel comprises air-air heat exchanger, hot reservoir and heater, and air flow passes through them in proper order with this.In order to set drying course readyly, air flow is activated and is heated by heater.Initially, heat exchanger does not have the cold air that is applied to it, makes air flow only be cooled by means of hot reservoir, and this hot reservoir is heated in this process.In case the heating of hot reservoir is enough severe, then heat exchanger will make cold air act on it, the cooling of the line space of going forward side by side air-flow; Then, hot reservoir no longer plays a part cooler, but plays a part to be used for the preheating gas device of air flow.Therefore, the heat energy that initially supplies to roller dryer is kept by drying course, and can not lose via heat exchanger at once; Certainly, only can realize little storage by this way, this is because only have the heat in the stage of self-starting drying course to be stored.
In the roller dryer according to DE10224940A1, hot reservoir has replaced the air-air heat exchanger of the processing air guide of sealing, and is to handle unique element that can receive heat in the air loop from the loop.Yet, in drying course, do not re-use this heat.On the contrary, hot reservoir must cool off after accomplishing drying course, and in drying course, hot reservoir is heated more or less, and the heat of accumulating will be from said hot reservoir discharging, so that can be used for a new drying course.For this reason, hot reservoir can remove from roller dryer, and can be in the device of independent release heat release heat.
Existing full automatic washer-dryer, the common major part of washing machine that promptly is integrated with dryer is used cold water, goes out the water (" condenser oven dry pattern ") that in drying course, evaporates from clothing with condensation.In this case, handle air flow and in device, transmit through the fan in the loop, whereby, air at first is heated.Then, this air is conducted through laundry drum, and at this, it draws moisture through transpiring moisture from the wet wash that this cylinder, rolls.In the remainder of this process, this air is conducted through condensing unit.There, it by the cold water cooling from the family expenses network of rivers, drops to below the dew-point temperature up to it usually.This makes airborne moisture produce condensation.Then, air is heated once more and is directed in the laundry drum.In this process, condensation heat is removed and is pumped out together with condensed water by means of emptying pump from airborne moisture by cold water.
From the AWD-AQ1 of Sanyo is can obtainable in the Japanese market full automatic washing-dryer, wherein, uses the water from storage bin to come the cooling processing air, and is directed turning back in this case.At this, storage bin is as the holder of the condensation waste heat of drying course.The deficiency of this solution is; Device needs high technical fee and space requirement; And in this solution, the water in the storage bin must come for example to prevent to pollute by means of ozone generating apparatus, or must be pumped away at the expiration in the predetermined storage time (for example 4 days).Also known such full automatic washing-dryer wherein, is handled air through the cooling of second cooling air flow.In this case, use is from the air cooling processing air of installation site.The used heat that is derived from condensation is discharged in the air of installation site at this.This is corresponding with the operation principle of the cylinder dryer of family expenses condensing at present commonly used in fact.Yet at this, heat exchanger, cold air fan and additive air passage need high engineering cost and space requirement.Panasonic provides a kind of full automatic washing-dryer, wherein, handles air by the cooling of the compressing hot pump in the condenser, is heated by used heat subsequently again.This is very energy-conservation embodiment, but related technical costs is also very high.
Summary of the invention
The purpose of this invention is to provide a kind of clothing drying device; Especially a kind of full automatic washing-dryer; But also relate to a kind of independent roller dryer; It can be only realized with relatively low hardware cost and running cost and with very compact mode, and operates with the mode of saving resource.
Above-mentioned purpose realizes through a kind of clothing drying device and a kind of method that is used for drying clothes according to corresponding independent claims.Preferred embodiment clothing drying device and said method is especially being put down in writing in the dependent claims.The preferred embodiment of clothing drying device is corresponding with the preferred embodiment of method, and vice versa, and this also is like this under various situation, only if spell out.
Correspondingly, clothing drying device of the present invention has: drum housing, said drum housing have the laundry drum that is received in it; And process air channel; Said process air channel fluid is connected to drum housing; Wherein, autonomous hot reservoir is arranged in the process air channel or on the process air channel, clothing drying device has the fluid distributor that is used for fluid is applied to hot reservoir.
Correspondingly, be used for the method for the present invention of drying clothes, handling air and be conducted through the autonomous hot reservoir that is arranged in the process air channel or on the process air channel, for heat of cooling reservoir, fluid is applied to hot reservoir.
Clothing drying device has rotating laundry drum and process air channel, and said process air channel fluid is connected to (promptly about gas and/or fluid) laundry drum.Autonomous hot reservoir is arranged in the process air channel or on the process air channel.
Usually, the process air channel fluid is connected to the both sides of laundry drum.In other words, process air channel and laundry drum are formed for handling the processing air loop that (oven dry and heating) handled air.Autonomous hot reservoir is interpreted as so hot reservoir, and this hot reservoir has just reached said purpose through being arranged on process air channel or the process air channel, and importantly not need with other function element for example heat pump be connected and work.In full automatic washing-dryer, laundry drum is supported in the drum housing (cleaning-drum) rotationally.
The humid air that comes out from the cylinder of full automatic washing-dryer has the relative humidity of approximate 80-90% and approximate 70 ℃ temperature usually, and the thermotropism reservoir discharges heat energy, and in this process, for example utilizes the latent heat reservoir to be cooled to dew-point temperature.Moisture is condensed out through this process again.So the heat energy of buffering can for example be discharged into the installation site via device wall through the free convection in the device case lentamente between the operating process of full automatic washing-dryer in hot reservoir.
This clothing drying device neither needs cold water, does not also need cold air to come the water of condensation from clothing evaporation, and can be implemented as very compact design, and can make with mode cheaply with simple, and need considerably less maintenance.
If after washing and drying course, just begin new washing and drying course at once, the cooling of hot reservoir can be preferably through using fluid cooling, preferred water to cool off it and strengthened.For this reason, the clothing drying device preferred fit is useful on the fluid distributor that the thermotropism reservoir applies fluid.
Comprise the flusher that is used for supplying with to drum housing water if clothing drying device is full automatic washing-dryer and fluid distributor, this fluid distributor can advantageously be realized especially simply and effectively.This makes the required water yield of washing can put into whole or in part at hot reservoir place or through condensing unit in the drum housing that is implemented as bucket.In this case, hot reservoir discharges heat energy with the temperature levels of thaw temperature to the water that gets into.Saved in the washing procedure of energy after tight that can be used in heated scrub water this this moment.Utilize warm water flushing also to improve developing result.In addition, in the drying process of warm clothing, obtain lower residual drying moisture than drying process at cold clothing.Make diminishing of the water yield wait to dry can cause reducing of in drying course energy consumption thus.
The water that is conducted through hot reservoir is used for washing out residue, velveteen and other pollutants that can get into the cleaning agent (foam) of processing air path at washing and drying course simultaneously, thus clean air path usually.
To implement in order making on the device technique simply, fluid distributor, preferably to be arranged on hot reservoir top in particular for the flusher of supplying with water.
In full automatic washing-dryer; If the reservoir capacity of hot reservoir fully by the used heat filling, then be used for supplying with the flusher of water also can be used for from for example drying course-equivalence-operator scheme " used heat is stored in the reservoir " transforms to-equivalence-operator scheme " reservoir cooling ".
This can preferably survey through one or more temperature sensors of handling in the air path, and wherein at least one temperature sensor is preferably placed at the exit of reservoir.If particularly the processing air themperature in hot reservoir exit is elevated to apparently higher than the thaw temperature of reservoir medium, then whole reservoir medium is melted and can not be received any energy that further melts.Heat is taken away from hot reservoir through " reservoir cooling ", and hot then reservoir is ready for once more and receives the other heat that is used for the clothing oven dry.The operator scheme conversion makes that also the continued operation with drying course becomes possibility, and the centre need not make hot reservoir discharge heat lentamente through free convection.As its a kind of alternative, the temperature difference between the entrance and exit of hot reservoir also can be surveyed, and this makes can more irrespectively carry out measurement with process and environmental change.Preferably, temperature survey also can for example be carried out through the hot reservoir material of temperature sensor direct sensing that imports in the hot reservoir.Fluid distributor can especially be triggered after a temperature threshold that meets or exceeds the thaw temperature that is higher than hot reservoir material.
Therefore; The advantage that above-mentioned clothing drying device has comprises: do not need the condensation cooling water to manage; Billy has simpler structure with the possible structure of air setting; Need not supervise the water yield of the water reservoir of use, through using warm water to save energy, improve and washed the result and/or can improve residual drying moisture level during washing operation under the situation of full automatic washing-dryer after carrying out drying course.
Hot reservoir preferably at least partly is implemented as the latent heat reservoir.This makes great amount of heat energy minimum space requirement to store.
Preferably, the thaw temperature of at least a hot reservoir material is 35 ℃-60 ℃, especially is 40 ℃-50 ℃.Because temperature equates with thaw temperature is approximate all the time under the situation of latent heat reservoir; If the reservoir material is in the phase transformation; In this case; Major part is between solid and the liquid, and the temperature of reservoir is difficult to basic change, and produces the temperature difference of constant size between condensing surface and the processing air.Preferred latent heat reservoir material comprises the material such as paraffin, salt, especially sodium sulphate (approximate 32 ℃ of melting point), sodium thiosulfate (48.5 ℃ of melting points) and/or sodium acetate (approximate 58 ℃ of melting point).Can use single latent heat reservoir material, or use the combination of multiple latent heat reservoir material, to cover wideer temperature range.The mixture that this combination can be used as different materials provides, or provides as the for example independent plate of structure that is provided with separately.
In order to obtain bigger condensing surface, preferably, thereby the hot reservoir material of hot reservoir is at least partly implemented with plate shape.
In order to have high efficient, hot reservoir preferably is arranged in the zone (drum outlet) of air feed opening of air duct.
In traditional full automatic washing-dryer, in order to dry, the clothing of maximum possible is separated (for example dividing half) earlier, subsequently with two continuous drying course oven dry.On the other hand, thus the thermal capacity of the current clothing drying device of the amount of reservoir material preferably is selected to and makes that to melt the heat heat more required than the full tube of oven dry clothing in washing process high slightly.This makes and can in hot reservoir, store all used heat that produce.For the hot reservoir capacity of the amplitude level of 200Kj/kg, the typical amount of latent heat reservoir material can for example be 15-20kg.
Under the situation of the advantageous embodiment of the inventive method, supply with water and be transmitted through hot reservoir as fluid and come heat of cooling reservoir.This particular importance when said method is used for roller dryer; This be because be used in this way washing process water can by means of before the heat that stores of drying course by preheating, thereby can in washing process subsequently, use from the energy of drying course.In this case, further preferably, for heat of cooling reservoir, supply water is transmitted through overheated reservoir and further arrives the drum housing that is connected to process air channel then.
Another advantageous embodiment according to the method for the invention, after a temperature threshold that meets or exceeds the thaw temperature that is higher than latent heat reservoir material, fluid distributor is triggered.This makes and can prevent that said method is owing to the exhausting of storage volume of hot reservoir receives influence unfriendly.
Another advantageous embodiment according to the method for the invention, after reaching or being lower than the temperature difference of hot reservoir between forward and backward, fluid distributor is triggered.As aforementioned improved substitute or additional, this also is used to prevent said method because the exhausting to receive unfriendly and influence of the storage volume of hot reservoir.
Description of drawings
Below, the exemplary embodiment of clothing furnace drying method is described in diagram in more detail.
Fig. 1 shows the cutaway view of watching from the side of clothing drying device.
The specific embodiment
Fig. 1 shows full automatic washing-dryer 1, and said full automatic washing-dryer has the drum housing of the form of bucket 1, and cleaning-drum 3 can rotate in said bucket 2.Process air channel 4 leads to the both sides of drum housing 2.In drying course; Handle air and be inhaled into through the air feed opening 6 in the rear wall 5 of bucket 2, and at first be conducted through condensing unit 8, at condensing unit 8 places by means of handling air fan 7; The cooling of processing air, thus condensation goes out to handle in the air moisture that is comprised.Condensed water is directed turning back in the bucket 2 through the lower area 9 of process air channel 4, and sends out through discharge-channel 11 by means of emptying pump 10 therefrom, and wherein, lower area 9 is implemented as down comb.The condensed water path illustrates with solid arrow.After process condensing unit 8; The processing air of doing this moment further transmits through heater 12; In heater, handle air and be heated to approximate 100-120 ℃ usually, blown to then in the upper area of sleeve 13 and and turned back in the bucket 2 through air outlet opening 14.Handling air flow representes with dotted arrow.
Condensing unit provides with the form that is arranged on the autonomous latent heat reservoir 8 in the process air channel 4, and said latent heat reservoir has into the heat storage material of the form of saltcake (being sodium sulphate), and saltcake has 32 ℃ thaw temperature.Latent heat reservoir 8 is as shown in the figurely with tabular enforcement.In order to make the processing air under 60-80 ℃ temperature that sucks from clothing preliminary condensation as few as possible, hot reservoir 8 is arranged on the location of air feed opening 6 or is adjacent to after the air feed opening 6.The common required amount of the clothing of the laundry drum 3 that the amount of the heat storage material of 15-20kg is more fully loaded than oven dry is big slightly.
Clothing drying device 1 also has the flusher 15 of the supply water that is used for bucket 2, and said flusher is arranged on hot reservoir 8 tops.Supply with and can open or close through valve 17 alternatively to the water of flusher 15, said valve is by control device 16 controls.This makes the required water yield of washing completely or partially perhaps to put in the drum housing 2 through condensing unit at hot reservoir 8 places.In this case, hot reservoir 8 discharges its heat energy to the water that flows under the temperature levels of thaw temperature.Therefore, the energy that is used for heated scrub water can be saved at the washing procedure after tight.Utilize warm water flushing also to improve developing result in addition.In addition, in the drying process of warm clothing than having obtained lower residual drying moisture in the drying process at cold clothing.The consequent water yield of waiting to dry reduce to make that energy consumption reduces in drying course.The water that is conducted through hot reservoir 8 is used for washing out residue, velveteen and other pollutants that can get into the cleaning agent (foam) of processing air path at washing and drying course simultaneously, thus clean air path frequently.
Shown in full automatic washing-dryer 1 in, flusher 15 also will be used at drying course heat of cooling reservoir 18.For this reason, approximate 0.5 liter/minute the less relatively water yield is conducted through hot reservoir 8 from flusher 15, is pumped out drum housing 2 subsequently.This cooling water flow can for example be everlasting in the drying course or be exhausted fully in the time of maybe will exhausting by used heat at the thermmal storage capacity of hot reservoir 8 and produced.
Exhausting at this of thermal capacity surveyed through temperature sensor 18,19, and said temperature sensor is installed in before the hot reservoir 8 and afterwards, the sensor values of temperature sensor can be received and estimated by control device 16 directly or indirectly.If the difference by the measured value of temperature sensor 18,19 sensings descends, especially covert etc., this means that latent heat accumulates medium and melt and can not receive any energy that further melts.Then, the current of cooling are activated.For this reason, temperature difference threshold value is stored in the control device 16, if reach or be lower than this threshold value, valve 17 is opened.On the contrary, cooling water flow can cut off after surpassing the for example bigger temperature difference of the specific temperature difference again.Alternatively, the duration of water-cooled also can for example store as fixing duration, and this provides enough cooling durations of confirming by rule of thumb.
Do not considering also can after drying course, to carry out water-cooled operation under the situation of thermal storage through free convection or the hot driving slowly through washing process.
Obviously, the present invention is not limited to described exemplary embodiment.Therefore, possibly produce in certainty of measurement under the situation of certain reduction, also a temperature sensor can only be provided in process air channel, preferably be arranged on thermal storage the exit or the outlet after.Also can between the cooling of the storage (for example, in drying course) of the used heat in the hot reservoir and hot reservoir, carry out unique conversion; At this moment, particularly stronger cooling water flow is preferred.Rise to apparently higher than the thaw temperature of reservoir medium 8 if handle air themperature, the processing air themperature that also can for example write down hot reservoir exit through temperature sensor 19 that exhausts of thermal capacity is detected; This also shows: whole latent heat reservoir medium melts, and can not receive and further melt energy.Other that are used to confirm possibly scheme comprise: the coolant-temperature gage of for example surveying through the flushing water of hot reservoir by means of temperature sensor 18.In order to finish water-cooled but, valve 17 is closed.
Obviously, the present invention is not limited to described embodiment.Therefore, the latent heat reservoir can also be used for independent roller dryer.Exhausting of the hot joining amount of accommodating of latent heat reservoir also can be through the direct sensing temperature identification at latent heat reservoir material place.
