Above-mentioned thermal insulation board 43 metal material such as handy iron plate is made, and also can make with the less plastics of thermal deformation (plastic).
Above-mentioned thermal insulation board 43 is by forming with the lower part, that is: basal part 43a is close on the bucket 20; The 43b of mold pressing portion, with the outer surface of above-mentioned bucket 20 at a distance of certain interval, drying pipeline 40 be fixed on it above.The central authorities of the 43b of mold pressing portion of above-mentioned thermal insulation board 43 have formed and have been used for connecting drying pipeline 40 pipeline connecting holes 432, that is to say to utilize above-mentioned pipeline connecting hole 432 to be connected the brace on the drying pipeline 40 410 on the above-mentioned mold pressing 43b of portion.In addition, the two ends of the above-mentioned mold pressing 43b of portion have also formed and have been used for thermal insulation board 43 is connected on the bucket 20 thermal insulation board connecting hole 431.
That is to say, in this example, formed thermal insulation board connecting hole 431 and pipeline connecting hole 432 simultaneously on the above-mentioned mold pressing 43b of portion.
In addition, determine the position of the connection bump 200 on the bucket 20 when installing, can be to carrying out mold pressing processing once more around the thermal insulation board connecting hole 431 that on the 43b of mold pressing portion of above-mentioned thermal insulation board 43, forms, thus form 2 43c of rank mold pressing portion.
Here, the brace 410 that is possessed on the above-mentioned drying pipeline 40 is given prominence to certain length downwards from the bottom surface of drying pipeline.
In addition, above-mentioned thermal insulation board 43 need have certain area, so that it can cover the photothermal conduction scope that heater produced in the drying pipeline 40.
In addition, the hot blast that forms on above-mentioned cylinder 30 is radial arrangement by hole 30a integral body.
In addition, the motor that is used for driving above-mentioned cylinder 30 is outboard rotor type (outer rotor) motor, and this motor is made up of the rotor 62 on the rear end of passing driving shaft 61 that above-mentioned bucket 20 is connected with cylinder 30 retainer shafts, being assembled in above-mentioned driving shaft 61, the stator 63 that is positioned at above-mentioned rotor 62 inside.The type of drive of above-mentioned cylinder 30 preferably adopts the mode of direct driving, and promptly aforesaid motor directly drives above-mentioned cylinder 30 rotations, but also might not be defined in this mode.
In addition, in order to enlarge area of dissipation, thereby superheating phenomenon appears in the top that prevents drying pipeline 40, and heat radiation pin 44 thermal components such as grade can be installed at the top of above-mentioned drying pipeline 40.
Have a look the effect that has the roller washing machine of drying function concurrently of the present invention below with said structure.
At first, upper end, the front of bucket 20 has formed hot blast inflow entrance 20a, and the lower end, back of bucket 20 has formed hot blast outlet 20b.
Why adopt this structure, be because this structure can make the inflow direction of the hot blast that flows to cylinder 30 inside and row just in time be on the diagonal to the discharge direction of the hot blast of condensation pipe 50, therefore can make above-mentioned hot blast arrive the depths of cylinder inside, after dry washings equably cylinder inside, discharge again.
Next, the hot blast inflow entrance 20a of bucket 20 forms in the upper end, front of bucket 20, the hot blast of above-mentioned cylinder 30 fronts is concentric circles by hole 30a and arranges in the front of cylinder 30, and these hot blasts can be shown in Fig. 4 a by hole 30a, being " one " font on radial direction arranges, also as described later shown in Fig. 4 b, on radial direction, be " it " font and arrange.
That is to say that the hot blast of cylinder 30 fronts will make the sectional area of passage bigger by the hole as much as possible on the intensity based that does not reduce cylinder 30 previous sections.
As mentioned above, because the hot blast that the whole front of cylinder 30 has all formed with effective and efficient manner arrangement the most passes through hole 30a, even 30 rotations of therefore above-mentioned cylinder, above-mentioned hot blast inflow entrance 20a also still can be connected by hole 30a with hot blast.So, the hot blast that flow into bucket 20 inside by hot blast inflow entrance 20a just can successfully flow into the inside of cylinder 30 by the hot blast of cylinder 30 fronts by hole 30a.
In addition, thermal insulation board 43 is housed below the above-mentioned drying pipeline 40, the heats that this thermal insulation board 43 can prevent to be produced in the drying pipeline 40 are to bucket 20 conduction.
That is to say, because if the inner drying pipeline 40 that the heater that can produce heat is housed directly is fixed on the bucket 20, cause bucket 20 temperature distortions of plastic material easily, therefore in order to prevent that the heat in the drying pipeline from directly conducting to bucket 20, above-mentioned thermal insulation board 43 has been installed especially, and this thermal insulation board 43 can play the 1st road heat-blocking action.
In addition, it still is not enough that above-mentioned thermal insulation board 43 only is installed, and this is to conduct supply barrel 20 once more because conduction can and be attached thereto the screw S that connects by the brace 410 on the hot drying pipeline 40 for the heat of thermal insulation board 43.Ways of addressing this issue is that mold pressing processing is carried out at the position that is connected with brace 410 drying pipeline on above-mentioned thermal insulation board 43, thereby make between the 43b of mold pressing portion of the outer surface of above-mentioned bucket 20 and thermal insulation board 43 at a distance of certain intervals, so just can play the 2nd road heat-blocking action.
For this reason, need during assembling earlier above-mentioned thermal insulation board 43 to be installed on the outer surface of bucket 20, under thermal insulation board 43 has been fixed on state on the bucket 20, utilize attaching parts such as screw S then, above-mentioned drying pipeline 40 is connected on the 43b of mold pressing portion on the above-mentioned thermal insulation board 43.
Here, the 43b of mold pressing portion that forms on above-mentioned thermal insulation board 43 need have sufficient height, so that be used for the screw that drying pipeline 40 is connected on the thermal insulation board 43 is also separated with bucket 20.
This is because if adopt the thermal insulation board 43 that does not possess the 43b of mold pressing portion, is used for so the screw that drying pipeline 40 is connected on the thermal insulation board 43 will be contacted on bucket 20.
In addition, the area of above-mentioned thermal insulation board 43 will guarantee the photothermal conduction scope that heater produced in the drying pipeline 40 is covered.
In a word, in the present invention, drying pipeline 40 is not directly to be connected on the bucket 20 of plastic material, but is connected indirectly on the mold pressing position of the thermal insulation board 43 that is connected with bucket, therefore say this structure heat conduction path that extended, can make bucket 20 avoid the influence of heat.
On the other hand, owing to above-mentioned drying pipeline 40 is to be fixed on the outer surface of above-mentioned bucket by means of above-mentioned thermal insulation board 43, be used for having absorbed the packing ring of vibration with regard to no longer needing to install on the connecting portion of therefore above-mentioned drying pipeline 40 and bucket 20.This is to be fixed on the bucket 20 because of drying pipeline 40, and therefore when above-mentioned bucket 20 produced mobile or vibrates, drying pipeline 40 always moved or vibration with bucket.
Certainly, go out in order to prevent the heat leakage in the drying pipeline 40, the connecting portion between above-mentioned drying pipeline 40 and the bucket 20 need be installed seal member.
In addition, because condensation pipe 50 also is the back that directly is fixed on bucket 20, therefore the connecting portion between above-mentioned condensation pipe 50 and the bucket 20 does not need to install the packing ring that is used for absorbing vibration yet.
Below the process that has adopted the roller washing machine that has drying function concurrently of the present invention with said structure to dry is illustrated.
If roller washing machine begins to carry out drying stroke, be installed in so on the heater 41 in the above-mentioned drying pipeline 40 and will connect power supply, also can connect power supply on the blowing fan 42 simultaneously, so, heater and blowing fan will be started working, thereby produce hot blast.
The hot blast meeting sequential flow that is produced in the above-mentioned drying pipeline 40 is crossed the hot blast inflow entrance 20a of above-mentioned bucket 20 fronts and the hot blast of cylinder 30 fronts passes through hole 30a, flow into the inside of cylinder 30 at last.
Here, owing to all formed hot blast in the whole front of above-mentioned cylinder 30 by hole 30a, and the arrangement mode of these hot blasts by hole 30a is on the intensity based that does not reduce cylinder 30 previous sections, can make the sectional area of passage bigger as much as possible, even therefore be under the state of rotation, corresponding to also occurring hot blast on the position of above-mentioned hot blast inflow entrance 20a by hole 30a at above-mentioned cylinder 30.
Therefore the hot blast that flows to bucket 20 inside by the above-mentioned hot blast inflow entrance 20a inside of cylinder 30 that can not need make a circulation to be fed directly to through other passage.
Next, the hot blast that flow into above-mentioned cylinder 30 inside can flow to the hot blast outlet 20b of the bucket that forms on diagonal, and hot blast moisture in the meeting absorption washings in the process of advancing, thereby realizes the oven dry to washings.
At this moment, above-mentioned cylinder 4 is low speed rotation one side agitator treating thing on one side, therefore washings is contacted equably with hot blast, thereby improves the drying efficiency of washings.
Here, above-mentioned cylinder 30 by low speed rotation washings stirred open in, under the state that stirs, can suitably improve the rotating speed of cylinder 30,, washings can not fall down the contact time that so just can make the hot blast that flow into above-mentioned cylinder 30 inside and washings that abundant length is arranged so that being attached on the inwall of cylinder 30.
As if in addition, the hot blast of having finished oven dry is not the state that reduces with temperature, is literal translation herein, but problem is arranged, and please note check and correction, the translator annotates but is discharged in the condensation pipe 50 with the state that is full of moisture.Here, because above-mentioned condensation pipe 50 is connected the lower end, back of bucket 20, and the hot blast inflow direction that this position just in time is positioned at cylinder 30 is on the catercorner direction in upper end of cylinder 30, and the air of discharging from cylinder 30 is arranged to condensation pipe 50 very wellly.
That is to say, because the air weight of this side of hot blast suction inlet of bucket 20 fronts is little and temperature is high, the air of this side of hot blast outlet of opposite bucket 20 back then relative weight is big and temperature is lower, so air circulation structure of the present invention, promptly form hot blast inflow entrance 20a, form the air circulation principle that this structure of hot blast outlet 20b meets free convection in the lower end, back of bucket 20 in the upper end, front of bucket 20.
In addition, in roller washing machine of the present invention, hot blast is discharged after can passing completely through cylinder 30 again, that is to say that hot blast can dry the washings that is positioned at the cylinder depths equably, therefore with compare before, can further improve drying efficiency.
On the other hand, for the humid air of discharging and flow into condensation pipe 50 from hot blast outlet 20b, because water feeder 51 can inject very cool condensed water in condensation pipe 50, therefore under the condensation of above-mentioned condensed water, the moisture that flow in the humid air in the condensation pipe 50 can be removed.
The air that has passed through dehumidification treatments in above-mentioned condensation pipe 50 is being installed under the effect of the blowing fan 42 in the drying pipeline 40, can flow into drying pipeline 40 again, after the heating of heater 41 through being installed in above-mentioned drying pipeline 40, these air can flow in the cylinder 30 under the effect of the air-supply power of blowing fan 42 once more.
Aforesaid cyclic process is carried out repeatedly, just can realize the oven dry to washings.
In addition, be to have formed in the mold pressing portion 43 of thermal insulation board 43 to be used for the thermal insulation board connecting hole 431 that is connected with bucket 20 though Fig. 3 to Fig. 5 shows, in fact also can adopt different structures.
For example, thermal insulation board 43 can be by forming with the lower part, i.e. basal part 43a, and it is close on the bucket 20; The 43b of mold pressing portion, the outer surface of it and above-mentioned bucket 20 be at a distance of certain interval, drying pipeline 40 be fixed on it above.Simultaneously, formed thermal insulation board connecting hole 431 on the above-mentioned basal part 43a, screw has been connected in the above-mentioned thermal insulation board connecting hole 431, just can be connected to above-mentioned thermal insulation board 43 on the bucket 20.In addition, formed on the 43b of mold pressing portion of above-mentioned thermal insulation board 43 and be used for drying pipeline 40 is connected to pipeline connecting hole 432 on the thermal insulation board 43.
