For the water of cleaning and filtering 173, can supply together with being fed to the washings of steel ladle 100.Alternatively, valve (not shown) can be arranged on the branch point place of branching hose 183 or be arranged in branching hose 183.Water is fed to the point of filter and can be controlled by valve.
According to the washing machine with functions/drying of embodiment, can comprise circulating drying system, it makes hot air circulate and without the condensation pipe being arranged on outside the steel ladle 10 of conventional washer.In other words, the conventional washer that has a functions/drying comprises for there is the auxiliary condensation pipe of condensation.Yet, according to the washing machine with functions/drying of embodiment by using the outer surface of surface, particularly cylinder 500, as condensing surface, condensation occurs on the surface of cylinder 500, and without auxiliary condensation pipe.
For this reason, cooling water can be used to cooling according to the cylinder 500 in the washing machine of this embodiment.Here, cooling water can be washings for washing supply, for being applied to the water of cleaning and filtering or being chilling roll 500 cooling water of supply in addition.
Hereinafter, will describe in detail according to the condenser system of the washing machine with functions/drying of above-described embodiment.
With reference to Fig. 2 to 5, using the embodiment of description, be that the water of supplying as washings is used to chilling roll 500 there is condensation on cylinder 500.
According to the washing machine with functions/drying of the embodiment shown in Fig. 2 and Fig. 4, comprise water supply hose 180, in order to the washings for being applied to washing.Water supply hose 180 can be fed to steel ladle 100 via detergent box (not shown) by washings.
Here, according to this embodiment, the water supply hose 180 being connected with steel ladle 100 can be connected to front surface or the outer surface of steel ladle 100.Alternatively, water supply hose 180 can be branched off into the front surface of steel ladle and be connected with outer surface.If water supply hose 180 branches, valve (not shown) can further be arranged in each branching hose, in order to open and close the path of washings.
Meanwhile, the water supply hose 180 being connected via the outer surface with the steel ladle 100 and washings of supply can be fallen the outer surface of the cylinder 500 that is arranged in steel ladle 100.In other words, the water supply hose 180 being connected with the outer surface of steel ladle 100 can be positioned at outside cylinder 500.
Be configured to injection and can be further arranged on the end of the water supply hose 180 being positioned at outside cylinder 500 from the injection nozzle (176, see Fig. 9) of the water of water supply hose 180 supplies.Washings are ejected into the outer surface of cylinder 500 dispersedly, with the more extensive and surface of chilling roll 500 promptly.
Meanwhile, when carrying out washing clothes, the washings of falling the outer surface of cylinder 500 can be stored in steel ladle 100, thereby after the outer surface along cylinder 500 flows down, are used as the washings of washing clothes.Yet, when drying clothes, drop on the temperature that washings on the outer surface of cylinder 500 can reduce cylinder 500, to allow cylinder to be used as cold plate.
Hereinafter, the embodiment of above-mentioned dry run will be described in detail.
First, when carrying out dry run, by being arranged on draft fan 210 in drying duct 200 and the dry air of heater heating, can be fed to cylinder 500 via hot air inlet 140.The dry air that is fed to cylinder 500 can be re-circulated in drying duct 200 via hot air inlet 150.
In above-mentioned process, dry air sucks cylinder with after drying clothes from the front portion of cylinder 500, can between cylinder 500 and steel ladle 100, discharge via the through hole 502 forming on cylinder 500.
The high temperature drying air being inhaled in cylinder 500 can contact the wet object to be dried holding in cylinder 500, and high temperature drying air is taken away moisture so that they are dry from object to be dried.In this process, high temperature drying air becomes low temperature moisture, and the through hole 502 that this low temperature moisture forms on can the wall surface via cylinder 500 is discharged into outside cylinder 500.
The air being discharged into outside cylinder 500 can flow between steel ladle 100 and cylinder 500, and the hot air outlet 150 forming with the rear portion via steel ladle rear portion 120 is discharged into outside steel ladle 100.
Now, chilled(cooling) water supply (CWS) is to the outer surface of cylinder 500, to improve condensation effect.By using the feed path of washings, can carry out the supply of cooling water.In other words, washings are via the feed path supply of washings, to contact with cylinder 500, thus chilling roll 500.Now, can supply than the water of the amount less amount of the washings that use in washing.In other words, can supply and only be enough to the surperficial water yield of getting cylinder 500 wet, to prevent from being leaked to (the residing space of object to be dried) in cylinder 500.
If the supply position of cooling water (position of injection nozzle 176) is eccentric with respect to cylinder 500 center, the supply centre of cooling water can cylinder 500 turn to the opposite direction with chilled(cooling) water supply (CWS) time the moment.This be because when cylinder 500 turn to the supply opposite direction with cooling water time, cooling water can spread the long period widely along turning on the surface of cylinder 500 of cylinder, to keep for a long time the cool time of cylinder.
Therefore,, due to the water via water supply hose (or injection nozzle) supply, the outside of cylinder 500 can maintain the temperature more relatively low than the temperature in cylinder.
Hereinafter, will describe in detail according to the condenser system of the washing machine with functions/drying of another embodiment.
According to another embodiment, as the water of cleaning filtration water supply, can be used to chilling roll 500, and on cylinder 500, condensation occurs.
With reference to Fig. 6 to Fig. 8, according to the washing machine with functions/drying of embodiment, can comprise and be arranged to filter the filter 173 of the fine hair during drying producing and be positioned at outside filter 173 in order to remove the cleaning filtration member 170 of the fine hair that filter 173 filters.Here, filter 173 can form the extension line of the interior perimeter surface of the steel ladle 100 on the path of corresponding hot air outlet 150, and air discharges by the path of hot air outlet 150.Filter cleaning member 170 can be ejected into steel ladle 100 by clean water from hot air outlet 150 is interior.
Here, can be by branching hose 183 supplies from water supply hose 180 branches to the clean water of filter cleaning element 170.Branching hose 183 can be from water supply hose 180 branches, and it may extend in hot air outlet 150, and making can be towards the internal spray of steel ladle 100 with cleaning and filtering 173 from the washings of the inside of hot air outlet 150.
Now, if branching hose 183 from water supply hose 180 branches, valve (not shown) can further be arranged in branching hose, to open and close the path of clean water.
Meanwhile, through after filter 173, from the clean water of cleaning filtration member 170 supplies, can be inhaled into steel ladle 100.Here, filter 173 can be positioned at the top of cylinder 500, through the clean water after filter 173, can drop on the upper outer surface of cylinder 500.And, for the clean water of cleaning and filtering 173, can spray by predetermined pressure, with cleaning and filtering 173.When the filter 173, with the clean water that predetermined pressure is sprayed, can be spread by gauze filter, can be more extensively, the surface of chilling roll 500 promptly.
In other words, when cleaning and filtering 173, from the clean water of cleaning filtration member 170 supplies, can be used as removing the clean water of staying the fine hair filter 173.Yet the clean water of falling the outer surface of cylinder 500 can be used for reducing the temperature of cylinder 500, so that cylinder becomes cold plate.
Hereinafter, will describe in detail according to the dry run of another embodiment.
When carrying out dry run, by the dry air that is arranged on draft fan 210 in drying duct 200 and heater 220 heating, can be fed in cylinder 500 via hot air inlet 140, the dry air that is fed to cylinder 500 can again be sought and being recycled in drying duct 200 via hot air outlet 150.
In above-mentioned dry run, dry air can be inhaled in cylinder 500, for dry object to be dried, then via the through hole 502 forming on cylinder, is emitted between cylinder 500 and steel ladle 100.
The high temperature drying air that is inhaled into cylinder 500 can be taken away moisture from object to be dried by contacting wet object to be dried, so that they are dry.In this process, the through hole 502 that high temperature drying air forms on can the wall surface via cylinder 500 and being discharged into outside cylinder 500 with the state of low temperature and moisture.
The air being discharged into outside cylinder 500 can flow between steel ladle 100 and cylinder 500, with the hot air outlet 150 forming on the rear portion via steel ladle rear portion 120, is discharged into outside steel ladle 100.
Now, cooling water can be fed to the outer surface of cylinder 500, and can strengthen condensation effect.Can carry out cooling water supply by using from the clean water of cleaning filtration member 170 supplies.In other words, washings, via the feed path supply of washings, then can be ejected into the outer surface of cylinder 500 for the clean water of cleaning and filtering 173, so that cylinder 500 is cooling.Now, the amount of the comparable clean water for cleaning and filtering of the amount of clean water is many or few.In other words, can only supply the amount of the surperficial clean water of the cylinder 500 that is enough to get wet, to prevent from being leaked to (the residing space of object to be dried) in cylinder 500.
If the supply position of the cooling water of filter 173 or cleaning filtration member (or position of injection nozzle 176) is eccentric with respect to cylinder 500 center, the supply centre of cooling water can be in the moment with the opposite direction of chilled(cooling) water supply (CWS) that turns to of cylinder 500.This be because when cylinder 500 turn to the supply opposite direction with cooling water time, cooling water can spread the long period widely along turning on the surface of cylinder 500 of cylinder, to keep for a long time the cool time of cylinder.
Therefore, owing to supplying clean waters from cleaning filtration member 170, so the outer wall of cylinder 500 can maintain the temperature relatively more much lower than the temperature in cylinder 500.
Simultaneously, if carry out chilling roll 500 by cooling water (washings or clean water) being fed to the outer surface of cylinder 500 as mentioned above, the cooling water that is fed to the outer surface of cylinder 500 can be inhaled in cylinder via the through hole 502 forming on cylinder by accident.In the case, the cooling water of the generation condensation of supply touches the clothing that carries out dry run, and clothing may become wet.Thus, can make drying effect variation.
In order to solve this shortcoming, with reference to Fig. 9 and Figure 10, describe and be configured to prevent that cooling water is via the structure in the through hole 502 inflow cylinders 500 that form on cylinder 500.
As shown in FIG., conventionally, cylinder 500 can rotate in steel ladle 100.On the outer surface of cylinder 500, can form a plurality of through holes 502, to discharge from the washings of clothing or object to be dried discharge.
The cooling water (for example, washings or clean water, hereinafter referred to as " cooling water ") that is fed to the outer surface of cylinder 500 during dry run can suck by this through hole 502.Meanwhile, the cooling water spraying to the outer surface of cylinder 500 can be ejected into the presumptive area of the outer surface of cylinder 500.Here, the presumptive area of injection cooling water can be cooling surface (A).Therefore all through holes 502 that, cooling water forms on can the front surface via cylinder 500 suck.Thus, cooling water can only suck by spraying the upper a part of through hole forming 502 of cooling surface (A) of cooling water.
Cooling water can be inhaled into the size capable of regulating of the upper through hole 502 forming of cooling surface (A) in cylinder 500, to prevent that cooling water is inhaled into.Here, the condition of the size of the intransitable through hole 502 of cooling water can be changed by the surface tension (that is, the weight of cooling water) of through hole 502.
Here, the equation of the surface tension in hole (Hst) will be following [equation 1]:
[equation 1]
Hst=γ * 2 π t
hole
Here, " γ " refers to surface tension coefficient, and " r
water" refer to the diameter of through hole 502.The weight of cooling water can be following [equation 2]:
[equation 2]
Here, " ρ
water" refer to the proportion of water, and " r
water" refer to the radius of cooling water droplet." G " refers to acceleration of gravity.
Therefore the condition (in other words, the maximum radius of through hole 502) that, makes cooling water droplet not be inhaled into the through hole 502 in cylinder 500 based on [equation 1] and [equation 2] can be calculated based on following [equation 3]:
[equation 3]
Hst≥Wg
According to [equation 3], can calculate enough large diameters (γ) that the cooling water of sening as an envoy to drips the through hole 502 that is not inhaled into.
Yet when carrying out when dry, cylinder 500 can be by presetting speed rotation, the diameter of through hole 502 can change more because being fed to blast and the above-mentioned condition based on [equation 3] of the dry air of steel ladle 100.In other words, in the situation that suck cooling water by the through hole of cylinder 500, the condition that sucks the through hole of cylinder 500 can change because of the blast of dry air.The diameter of the through hole 502 calculating based on [equation 2] can be to be enough to minimum diameter that cooling water is not sucked by through hole.
Therefore the blast (Wp) that, is fed to the dry air of steel ladle 100 can calculate based on following [equation 4].
[equation 4]:
[equation 4] is applied to [equation 2] and obtains following [equation 5].
[equation 5]:
Therefore, consider the condition of the blast of the diameter that is applied to through hole 502 calculating based on [equation 2], the through hole 502 forming on the cylinder 500 conventionally consisting of non-corrosive material can have the radius of 2～3mm.Cooling water can not be inhaled in the through hole that radius is 2.7mm.Yet, consider the blast condition of dry air, the diameter of through hole 502 can expand when blast condition increases.
As mentioned above, the position of the through hole 502 forming on cylinder and size capable of regulating, so it can prevent from being inhaled in cylinder 500 to the jet surface of cylinder or the cooling water falling.
Alternatively, the washings that the rotating speed of cylinder 500 can increase to the outer surface that prevents from being fed to cylinder 500 are inhaled in cylinder 500 via through hole 502.Here, cylinder 500 can rotate by desired speed, and this desired speed enough high so that washings that rest on the outer surface of cylinder 500 can not be inhaled in cylinder 500 via through hole 502.
For example, the rotating speed of cylinder 500 can maintain the scope of 40～110rpm during dry run.Preferably, the rotating speed of cylinder 500 can be 5070rpm.Conventionally, when the rotating speed of cylinder 500 is 110rpm or when higher, the clothing holding in cylinder 500 can rotate in intimate contact with the interior perimeter surface of cylinder 500.In the case, clothing can not effectively mix with dry air, drying efficiency possible deviation.Therefore, the rotating speed of cylinder 500 can equal 110rpm or less.In other words, rotating speed must maintain enough height, to rotate not the clothing with the interior perimeter surface close contact of cylinder 500, thereby clothing is mixed with dry air.
Therefore,, when cylinder 500 rotation, the washings (that is, being supplied the washings with chilling roll 500) that the centrifugal force of cylinder 500 can prevent from resting on the outer surface of cylinder 500 are inhaled in cylinder 500 via through hole 502.
