Summary of the invention
Under this background, the objective of the invention is to, a kind of method is provided, can in clothes washer-dryer, from washings, remove odoriferous substance by this method simple and reliablely.The objective of the invention is in addition, provide a kind of clothes washer-dryer that is applicable to this method.This clothes washer-dryer is with easy operating and have simple structure.
The object of the invention realizes according to described method of corresponding independent claims and clothes washer-dryer by a kind of.Preferred configuration of the present invention is enumerated in each dependent claims.Even if here do not point out separately respectively, according to the preferred configuration of clothes washer-dryer of the present invention also corresponding to the preferred configuration of the method according to this invention.
Therefore, theme of the present invention is a kind of method that is used for removing from the washings of clothes washer-dryer odoriferous substance, wherein, this clothes washer-dryer has alkali liquor container, is rotatably supported in the cylinder, control device and the process air duct that are used to hold washings in the described alkali liquor container, be useful on heater, fan and the heat exchanger that adds hot-air in this process air duct, this method may further comprise the steps:
(a) produce hot air flow, its mode is to carry with air heat and by described fan by described heater in described process air duct;
(b) be immersed in described amount in liquid, aqueous with a not enough so that described cylinder and import in the alkali liquor container liquid, aqueous through described heat exchanger;
(c) make described liquid, aqueous by coming in contact and heating with described thermal air current;
(d) by making described liquid, aqueous the evaporation at least in part produce water vapour stream; And
(e) described water vapour stream is come in contact with described washings.
In the method according to the invention, preferably step (a) to (e) repeatedly or on the long time period is carried out constantly.This especially guides in the closed to a great extent closed circuit in the process air duct by thermal air current and carries out.
In the method according to the invention, the contents increased of moisture in the air.During beginning, in step (a),, produce the dry air stream of heat from dry air.When the thermal air current of drying and liquid, aqueous coming in contact, the content of moisture rises in the air, thereby produces wet thermal air current by heater and fan when re-executing step (a), or the like.Along with liquid, aqueous heating more, the moisture content in the hot-air further raises, and finally reaches quite a large amount of vapour contents, for example at least 5% volume ratio.Just we can say in the time of the latest to this water vapour stream to occur, promptly realized step (d).If this water vapour stream has passed through heater and fan, this water vapour stream is exactly the thermal air current in the step (a).
In a preferred implementation of this method, liquid, aqueous being heated in step (c) is at least 50 ℃, more preferably at least 60 ℃ temperature T
LiqPreferred again at this, liquid, aqueously on predetermined time Δ t, remain on this temperature T
LiqIn order to control water temperature, preferably in alkali liquor container at cylinder arranged beneath one three-temperature sensor T3.
In step (c) and then in step (e), not only liquid, aqueously be heated and form gradually thus damp and hot atmosphere, this damp and hot atmosphere can be used as water vapour stream and is used to carry out water vapour and extracts.By hot-air the washings in the cylinder is heated.At first Gan Zao hot-air becomes more and more wetter, therefore, is accompanied by washings also along with hot-air humidity increases and heating, and the odoriferous substance that can take place not expect extracts from the water vapour of washings, removes thereby smell takes place.
Yet in a preferred implementation of the inventive method, the washings in the cylinder is preheated in step (d) before coming in contact with water vapour stream.Preferably in step (a), washings is preheating to 35 ℃ to the 50 ℃ temperature T in the scope with hot-air before in step (b), importing liquid, aqueous
TexWherein, between warming up period, preferably make cylinder for example to rotate with the revolution in 40 to 60 rev/mins of scopes (for example washing 50 rev/mins of rotating speeds).
For this reason, for example in 5 minutes, under the situation that fan is connected and heater is connected, washings is heated to about 40 ℃.At this, cylinder for example in antiport with the running of 50 rev/mins revolution.
Before cylinder, can preferably import to the temperature of the hot-air in the cylinder or in the alkali liquor container by the first temperature sensor T1 measurement.In the method according to the invention, preferably under the situation of using described first temperature sensor T1 and control device, regulate fan and heater so then, make the predetermined maximum of T of temperature (also can be called " being blown into temperature ") of the hot-air that is no more than temperature, promptly imports for thermal air current
Max, for example 65 ℃.In order to control the heating of washings, the second temperature sensor T2 can also be arranged in the transition piece between alkali liquor container and dryer.
In the method according to the invention, liquid, aqueously import through over-heat-exchanger.Its advantage especially is, washings can not be directly comes in contact and wetting with liquid, aqueous.Liquid, aqueous flushing liquor or the cooling medium that is used for heat exchanger that be preferably.
In the clothes washer-dryer of contained moisture condensation on heat exchanger, heat exchanger generally moves or uses the cooling medium operation of heat pump under the situation of using heat pump with cold air, cold water in damp-heat air.
If heat exchanger moves with cold water, can (by using suitable valve) stipulate that then the water that is used for cooling off imports in the alkali liquor container as the liquid, aqueous wall through over-heat-exchanger, especially heat exchanger of step (b).At this, cold water is usually through its outside wall surface that under normal circumstances comes in contact with the process air and to dirty, there, the process air duct is connected with alkali liquor container by transition piece.
If opposite heat exchanger cools off with air, then can be heat exchanger one overflow cascade washers is set, this overflow cascade washers cleans the fine hair that adheres to and other fouls of heat exchanger.Also can be used as liquid, aqueous in the step (c) of the inventive method at this used trickle that dashes.
Alkali liquor container in the above two kinds of cases all water be filled to such degree, make cylinder still be not immersed in liquid, aqueous in.Can stipulate that for this reason in " water vapour extraction " program that can set on clothes washer-dryer, inject the water of predetermined amount, this amount meets this indication.
This for example can carry out like this: under the situation that heater cuts out and fan cuts out, drench into device to import water by the overflow cascade washers of air-cooled type clothes washer-dryer or the cold water of water-cooled clothes washer-dryer much more like this, making has 1L water approximately below cylinder in alkali liquor container.At this, the wall of heat exchanger is coated with moisture film.
If mention " heater " here, then be meant to be arranged in to be used for air (process air) heater in the process air duct.In addition, dryer also has usually and is used for that directly heating is liquid, aqueous, the heater of for example washing soda liquid.This heater that is known as water heater here is arranged in below the cylinder in alkali liquor container usually.
Therefore because do not need to hide the water heater in the lower area that is usually placed in alkali liquor container this moment in the method according to the invention, the requirement to the adjusting of liquid, aqueous horizontal plane can not improve.Because liquid, aqueous supply can be carried out not cause the wetting mode of washings in addition usually; therefore, being used to of may need in some cases not needing in this embodiment avoid washings wetting, to the requirement of the through-current capacity of valve or be used to guide the measure of water.
In this embodiment, make in alkali liquor container and in process air duct lower part and the water that in the heat exchanger outside wall surface, exists evaporation, to produce water vapour and wholely to form damp and hot atmosphere by thermal air current.The water vapour that produced stream (may also contain interim assistant) flow through in the cylinder washings and take away the odoriferous substance at this place.
According to used in the present invention mainly liquid, aqueous or only constitute by water.At this, liquid, aqueously can be added with additive, these additives are used for extracting odoriferous substance better or are used for other purposes (for example sterilization).
In step (e), promptly when water vapour stream comes in contact with washings, cylinder is turned round in antiport.
Especially advantageously, in (e), the cooling device of heat exchanger is closed in step (a), and this cooling device can come cooling heat exchanger by importing cold air or cold water.Can avoid water vapour to be condensate on the heat exchanger thus.Can avoid being used for the unnecessary energy consumption of cooling heat exchanger in addition, this energy consumption is not just in time expected in these steps.
In the method according to the invention, repeat usually or execution in step (a) is to (e) on long time period, wherein, humidity increases and the hot-air that is rich in water vapour is directed in the loop.At this, a preferred predetermined processing time.Also available in case of necessity smell sensor comes qualitatively or adhering to of sensing odoriferous substance quantitatively.By adhering to of the odoriferous substance of sensing, can obtain automatically and set-up procedure (a) to the setting of (e) and especially obtain the total duration of these steps, perhaps manually predetermined by the user.
In step (a) to (e) afterwards and then, preferably in step (f), the pump sucking-off is liquid, aqueous from alkali liquor container.Then, the washings that becomes wet is extracted in preferred oven dry owing to water vapour.Washings can come dry in a step (g) by common seasoning.
Because therefore washings heat and be not very wet usually relatively after water vapour extracts preferably come execution in step (g) like this, make fan heater close and the situation of the cooling device connection of heat exchanger under turn round.The cooling device of heat exchanger turns on this and especially means, for the air-cooled type dryer cooling fan is connected and is then connected cold water supply apparatus for the water-cooled dryer.
The air that circulates in the process air loop is cooled and is dried when contacting with cooled heat exchanger.Fine hair, dust and odoriferous substance are deposited in the heat exchanger or discharge to liquid, aqueous simultaneously, and then can be pumped out, and for example are pumped out to outlet by waste water pump.
In step (g), cylinder preferably turns round in antiport equally.
For fear of in washings, forming gauffer, can and then connect the wrinkle resistant stage afterwards at step (g), in this stage, carry out the superimposed again of washings sometimes.
The invention still further relates to a kind of clothes washer-dryer, comprise that an alkali liquor container, is rotatably supported in cylinder, a control device and a process air duct that is used to hold washings in the described alkali liquor container, one heater, a fan and a heat exchanger that is used to add hot-air arranged in this process air duct, wherein, described control device is set to be used to the method implementing to comprise the steps:
(a) produce hot air flow, its mode is to carry with air heat and by described fan by described heater in described process air duct;
(b) be immersed in described amount in liquid, aqueous with a not enough so that described cylinder and import in the alkali liquor container liquid, aqueous through described heat exchanger;
(c) make described liquid, aqueous by coming in contact and heating with described thermal air current;
(d) by making described liquid, aqueous the evaporation at least in part produce water vapour stream; And
(e) described water vapour stream is come in contact with described washings.
Therefore, in clothes washer-dryer of the present invention, directly in cylinder, carry out water vapour and extract, make in the washings contained odoriferous substance can be removed by water vapour and contain the liquid, aqueous of odoriferous substance and discharge by from clothes washer-dryer, pumping.
In a preferred implementation of the present invention, arranged in the process air duct that also is used to remove the filter that can not be collected in those odoriferous substances in liquid, aqueous.
In addition, this clothes washer-dryer also can be provided with condensed water collecting device, makes also to use liquid, aqueous as on the meaning of the present invention of the condensed water that gathers when dry washing material.
