The shaft center line that the central axis of outer bucket 2 was configured in and washed dry bucket 11 is with in the heart, and is made as identical angle of inclination.
Housing cabinet 1 has input port 11c in the front side.The input port 11c of housing cabinet 1 be set to wash dry bucket 11, and the input port equidirectional of outer bucket 2 consistent, possess switch enclosing cover 12 freely.The discrepancy of washings is opened enclosing cover 12 and is carried out.
Be installed on the inner edge portion of input port of the mouth edge part of input port 11c of housing cabinet 1 and outer bucket 2 bellows 21 watertights.Watertight utilization between housing cabinet 1 and the outer bucket 2 is kept by the bellows 21 that elastomer constitutes.Therefore, enclosing cover 12 inboard with bellows 21 driving fits, so do not produce input port 11c leaking to the outside from housing cabinet 1.
The dry bucket of washing 11 peripheries at input port 11a have balancer 13.Vibration when utilizing this balancer 13 to reduce dehydration.And the dry bucket of washing 11 has a plurality of dewatering holes 14 in cylindrical portion.When dehydration, the moisture that is contained in the washings 9 passes through the outwards bucket 2 interior dehydrations of dewatering hole 14 usefulness centrifugal force.
On the cylindrical portion of the dry bucket 11 of washing, be provided with a plurality of (3) lifter 16.This lifter 16 prolongs along the direction of shaft center line.The height of lifter 16 is roughly the same height usually in the scope of length direction.Also have in order to make the action that is positioned at inboard washings 9 good, lifter 16 is the situation of the axis of rotation approximate horizontal of the dry bucket 11 of washing relatively.At a plurality of (3) lifter 16 is 3 occasion, with the uniformly-spaced configurations of 120 degree.
DC Brushless Motor 19 installs and fixes the outside, rear portion of bucket 2 outside.This DC Brushless Motor 19 is drive sources that rotation drives the dry bucket 11 of washing.
The dry bucket 11 of washing has flange 17 in the rear end as the bottom side of cylindrical portion.The main shaft 18 that is located on the flange 17 combines with the rotor-side of DC Brushless Motor 19.Like this, the dry bucket 11 of washing is supported on the outer bucket 2 freely by DC Brushless Motor 19 rotations of drive source.
By open operation drain solenoid valve 22, the washings or the washings that accumulate in the outer bucket 2 pass through scupper hose 23 drainings.
Heat pump assembly 70 is installed in the close preceding side lower part of input port 11b with outer bucket 2.
The dryings that 70 pairs of this heat pump assemblies circulate in the dry bucket 11 of washing dehumidify with air and heat and more effectively carry out the drying of washings 9.
Moist drying is discharged with the exhaust outlet 2a at air rear portion of bucket 2 outside being located at.The drying air of discharging utilizes Air Blast fan 24 to be transported in the heat dump 52 by circulation canal 23a.Heat dump 52 is drawn by condensing effect and is contained in the dry airborne moisture of using.The condensing water of drawing flows through dew and is discharged to outside the machine with scupper hose 27, drain solenoid valve 22, scupper hose 23.
The drying of dehumidifying, flows in the dry bucket 11 of washing from input port 11b by circulation canal 23b with radiator 53 heating with air.
The outer bucket 2 that is obliquely installed, the center of gravity of whole outer bucket are near DC Brushless Motor 19 sides, and the suspension bracket 3 that supports outer bucket 2 supports the roughly position of centre of gravity of outer bucket 2.
After washing, rinsing finish, occasion at the moisture of sloughing washings 9, because the dry bucket 11 of washing tilts, therefore relatively wash a side of the inside of dry bucket 11 at washings more than 9, promptly be provided with under a side the state of DC Brushless Motor 19, the moisture that makes washings 9 by centrifugal force from dewatering hole 14 dehydrations.
During dehydration, dewater under the state as if the inwall that is evenly dispersed in washing drying bucket 11 at washings 9,, but need only inhomogeneous a little big vibration or the noise of just taking place even big vibration, noise do not take place the 11 high speed rotations of then washing drying bucket yet.
Therefore, at the peristome of the dry bucket 11 of washing, be provided with the balancer 13 of the vibration when being used to reduce dehydration.
The bottom of bucket 2 is provided with compressor 15, radiator 53 or the heat dump 52 etc. of heat pump assembly 70 outside.By the compressor 15 of Heavy Weight is set on the position close with the input port 11b of the dry bucket 11 of washing, the position of centre of gravity of outer bucket 2 roughly is positioned at the center (front and back central authorities) of outer bucket length direction.
Make the strong point of suspension bracket 3 also be positioned at outer barrel 2 front and back central authorities.Thus, even under washings 9 uneven states, dewater during dehydration, also reduce the vibration that causes by the imbalance around the 11a of input port.Vibration when therefore, making dehydration, the reductionization of noise act on effectively.
Suspension bracket 3 can improve the height of suspension bracket 3 by the central mobile position, front and back from the outside bucket 2 of rear side, and the high damping mechanism portion of attenuating can be set.
Particularly the dehydration occasion, if be positioned at the dry bucket 11 of washing rotation at a high speed under the state of input port 11a side of the dry bucket 11 of washing in the part of washings 9, then will vibrate with the state of drawing big ellipse as the input port 11b side of the outer bucket 2 of axle with the part that suspension bracket 3 supports, so the vibration when not only making dehydration, noise become big, and the life-span of each several part is reduced significantly.
This unusual vibration is reduced with balancer 13, but in order further to reduce vibration, the input port 11b side bottom that the compressor 15 of heat pump assembly is installed in outer bucket 2 works as counterweight, thus vibration, noise when reducing dehydration.
To the circulating water pipe 64 of spray water nozzle 65 supply washings, in the radiator 53 via heat pump assembly, be connected communicatively with the drainage channel of communicated drainage electromagnetic valve 22 with the rear lower of outer bucket 2.In the way of circulating water pipe 64, be provided with sprinkling pump 120 from washings to spray water nozzle 65 that carry.
In radiator 53, be provided with the heat exchanger (not shown) that heating flows to the washings of circulating water pipe 64.Flow through circulating water pipe 64 and heat with heat exchanger from the spray water that spray water nozzle 65 sprays.
When washing, washings 110 accumulate in the interior bottom side of washing dry bucket 11, reaching bucket 2 as shown in Figure 1.The dry bucket 11 of rotation washing washs under this state.Become washings sprinkling above washings 9 of warm water according to this washing action, so clean well.
That is in the scrubbing-and-drying unit of drum-type, be the so-called beat type (formula is washed in bat) that falls washings in the few place of washings,, so wash on the basis of exposing from washings.Therefore, by spray the washings that become warm water on the washings that exposes, inviolateness ground is cleaned well.
Fig. 7 represents the temperature of washings and the relation of wash degree.
Water spray is cleaned and is not had water spray and clean and compares, at wash degree height in all directions.And, find to clean the temperature wash degree raising of water along with improving water spray.
By the washings of such sprinkling warm water, can improve the washing (-)off properties of scrubbing-and-drying unit.
In addition, when the washing running, carry out following Natural Circulation as shown in Figure 8, promptly the washings of heating with the radiator 53 of heat pump assembly flow through circulation canal 23b from the dry bucket 11 of exhaust outlet 2b inflow washing.
Further, quote the discharge that Fig. 5, Fig. 6 append the condensing water of explanation when drying.
The inboard of heat dump 52, radiator 53 becomes the dry heat exchange stream that carries out heat exchange with circulation of air.Dry mobile from heat dump 52 to radiator 53 with air.The heat dump 52 of upstream side is configured in low position, and the radiator 53 in downstream is configured in high position.
At the condensing water that heat dump 52 takes place, do not flow to a side of radiator 53, and under low side's spontaneous current of heat dump 52, from the dew scupper hose 27 that is communicated with the low position of heat dump 52 flow through drain solenoid valve 22, scupper hose 23 is discharged to outside the machine.
Because condensing water do not remain on the heat exchange stream,, carry out the drying of washings well so do not produce obstacle with on air mobile in drying.
Dry with air circulation in the dry bucket 11 of heat dump 52, radiator 53, circulation canal 23a, 23b, Air Blast fan 24 and washing of the heat pump assembly 70 that is installed on bucket 2 by making like this, the washings 9 in the dry bucket 11 of washing is dried.
In addition, the kind as compressor has reciprocating manner, rotation mode and linear fashion.In any way can make.
But, owing to need make all compact dimensions of heat pump assembly, compressor is made the linear fashion of using DC Brushless Motor with drive motor, this DC Brushless Motor is used the magnet with the terres rares of neodium magnet, can make noise, vibration is little and compressor excellent in efficiency is used motor thus.
Then, other embodiment shown in Figure 2 is described.
Here, the main narration place different with the embodiment of Fig. 1.Common place is only limited to the common symbol of mark.
Heat pump assembly 70 mainly comprises compressor 15, heat dump 52, radiator 53 and adjusts valve 26 or Air Blast fan 24.
As quote Fig. 1 explanation, these heat pump assemblies 70 are arranged on from supporting outside barrels 2 the center of gravity place near input port 11b, promptly the place ahead to the position.As with compressor 15 refrigerant compressed, use carbon orgon compound or carbon dioxide, but in recent years because factors such as environment ban use of the carbon orgon compound, so mainly use carbon dioxide.
Return by radiating tube 55, adjustment valve 26, endothermic tube 54 with compressor 15 refrigerant compressed, send from compressor 15 once more.
This is cold and hot to be delivered on the heat dump 52 effectively from endothermic tube 54, and the temperature around making reduces.High temperature of sending here by circulation canal 23a and moist drying be condensing and dewfall (condensing) with air.The dew of dewfall is discharged from dew scupper hose 27.
This heat pump assembly, its part has been practical by air-conditioning etc., and the device of the heat that the cold-producing medium of applied compression takes place also is practical.
If compressor 15 is output as about 400W, then refrigerant compressed obtains about 3～6 times heat energy of the output of compressor 15.The drying of the high temperature that humidity is high utilizes Air Blast fan 24 to be transported to the heat dump 52 by circulation canal 23a with air from the air entry 2a at the rear portion of outer bucket 2.Here, dry moisture with air is cooled into to condensing water and is drawn, so drying becomes the drying air of the low low temperature of humidity with air.
Become the drying air of low humidity, with the drying air of radiator 53 heating becoming the once more low high temperature of humidity.The drying of this low humidity and high temperature flows through circulation canal 23b with air delivers to the dry bucket 11 of washing from exhaust outlet 2b, thereby carries out the drying of washings 9.
The moisture of absorption washings becomes the drying of high humidity with air backflow in the dry bucket 11 of washing, discharges from air entry 2a once more.
Spray water nozzle 65 is located at the input port 11b upper lateral part of bucket 2.The direction of spray water nozzle 65 is towards the interior side of the dry bucket 11 of washing, so spray water is sprayed on the washings 9 that is built in the dry bucket 11 of washing.
The washings side radiator 66 of heated scrub water is connected communicatively.The downstream of washings side radiator 66 is connected with spray water nozzle 65 communicatively by discharging side circulation pipe 67.
The upstream side of washings side radiator 66 is connected with the draining road of communicated drainage electromagnetic valve 22 with the rear lower of outer bucket 2 communicatively by suction side circulation pipe 64.On suction side circulation pipe 64, be provided with sprinkling pump 120 from washings to spray water nozzle 65 that carry.
Washings in the outer bucket 2 are transported to and spray with in the pump 120, flow through suction side circulation pipe 64, washings side radiator 66, discharge on side circulation pipe 67 is sprayed at washings 9 in the dry bucket 11 of washing from spray water nozzle 65.The washings that sprayed become warm water by 66 heating of washings side radiator, so wash the dirt of washings well off.
Washings side radiator 66 has the radiating tube 550 that washings are used.Radiating tube 550 is in the downstream of radiating tube 55 and adjust between the upstream side of valve 26 and connect communicatively.Refrigerant flow direction radiating tube 550, washings side radiator 66 is heated.
The washings that the 66 special heating of washings side radiator are sprayed by spray water nozzle 65.The special heating of radiator 53 drying with air flow path in mobile drying air.Radiator 53 is the dry air side radiators of using.
By separate drying with air side radiator and washings side heat radiation 66, the drying air side radiator of the scrubbing-and-drying unit of the structure that is used for not heating the washings that flow to spray water nozzle 65 but former state is migrated.
Then, quote heat dump that Fig. 5, Fig. 6 illustrate heat pump assembly, and radiator.
The main narration place different with the embodiment of Fig. 1 and Fig. 2, the common place common symbol of mark omits its explanation.
As previously mentioned, because heat dump 52 becomes low temperature, therefore be cooled with air from the high temperature that washs dry bucket 11 discharges, the drying of high humidity.By condensing and become dew with the moisture of air drawn, by 27 drainings of dew scupper hose from drying.
Heat pump assembly is provided with along the outer bucket 2 that tilts, thus heat dump 52 and radiator 53 also tilt, by condensing dew from dew scupper hose 27 draining naturally.
Because the radiating tube 55 in the radiator 53 becomes high temperature (about 80～100 ℃), therefore drying flows into air in the dry bucket 11 of washing with the drying that air is heated as low humidity, high temperature, carries out the drying of washings.
Heat dump 52 has heat absorption cylindrical shell 61, endothermic tube 54 and heat-insulating material 56.
Heat absorption cylindrical shell 61 usefulness thermal conductivity good metal form, and are formed with the helicla flute of extension.Interior all sides at heat absorption cylindrical shell 61 form dry heat exchange stream with circulation of air.
Endothermic tube 54 usefulness thermal conductivity good metal pipes form, at the internal circulation cold-producing medium.This endothermic tube 54 is configured in the outer circumferential side of heat absorption cylindrical shell 61, and embeds helicla flute along its installation of reeling.
As shown in Figure 6, heat absorption cylindrical shell 61 and endothermic tube 54 usefulness thermal conductivity good metal form, and make endothermic tube 54 embed helicla flutes and engage, so the cold-producing medium heat of endothermic tube 54 is delivered on the cylindrical shell 61 that absorbs heat well.
On the inner peripheral surface of heat exchange stream of heat absorption cylindrical shell 61, extend to form concavo-convex helicla flute, so enlarge with the contact area of drying with air.Carry out and drying the contacting of here circulating with air morely.And, on one side the drying air that flows on one side with the collision of concavo-convex helicla flute, private side and outer side are replaced well, and the heat of cooling has the ground of omission and is not delivered to drying with on the air, so the heat exchange performance raising.
And, extend to form concavo-convex helicla flute, the inner peripheral surface of heat exchange stream of heat absorption cylindrical shell 61 is compared with the fin that existing heat dump or heat dump possess, and produces adhering to of the debris that comes out from washings or broken the end of a thread hardly, can not hinder dry flowing with air.And, on the inner peripheral surface of heat exchange stream, do not become the part of seamed edge, so debris or broken the end of a thread are non-cohesive, so heat exchange performance does not reduce and is kept.
The inflow oral-lateral of heat absorption cylindrical shell 61 is connected with circulation canal 23a, flows out oral-lateral and is connected with connecting duct 59, gets involved sealing gasket 57 in order to improve sealing at connecting portion.Thereby prevent the outflow of drying mobile in the heat exchange stream of heat absorption cylindrical shell 61 with air or condensing water.
The periphery of endothermic tube 54 or heat absorption cylindrical shell 61 is with breaking off heat-insulating material 56 coverings that heat is transmitted well.Heat-insulating material 56 usefulness heat dump covers 62 cover periphery universally.The one distolateral sealing gasket 60 that passes through of heat dump cover 62 engages with the inflow entrance periphery of heat absorption cylindrical shell 61.Another of heat dump cover 62 is distolateral to be engaged by the flow export periphery of sealing gasket 60 with heat absorption cylindrical shell 61.
Heat dump 52 usefulness heat-insulating materials 56 cover, and cover universally with heat dump cover 62 and carry out the sealing of both end sides, so the cold and hot outside that do not drain to of cold-producing medium.Therefore, the drying that circulates in the heat exchange stream is cooled effectively with air.
The air supply direction conversion is handled knob and 58 is located in the inflow entrance of heat dump 52.On 58 periphery is handled knob in the air supply direction conversion, be provided with many and bend to spiral helicine deflector vane.
Utilize handle knob 58 deflector vane of this air supply direction conversion, the drying air that the high temperature of sending here with Air Blast fan 24 is how wet flow in the heat exchange stream of heat absorption cylindrical shell 61 rotatably, and an edge helicla flute flows on one side towards the flow export of the cylindrical shell 61 that absorbs heat.
Utilize the air supply direction conversion to handle knob 58 dryings that increase rotation, spread all over depths, spiral fluted the inside, so heat absorption cylindrical shell 61 and dryly carry out the heat exchanger effectiveness raising well with the heat exchange of air with the flowing of air.
The radiator 53 and the heat dump 52 that are configured to this position relation up and down dispose obliquely, so condensing dew flows downwards naturally in heat dump 52, from 27 drainings of dew scupper hose.
And, because on the heat exchange stream of radiator 53 and heat dump 52, do not produce the obstruction that the cloth bits that take place from washings etc. adhere to, so carry out dryly smoothly, carry out the drying of washings well with the flowing of air.Also have, because non-cohesive cloth bits etc., so also good under the spontaneous current of dew, the drying on the heat exchange stream is carried out well with the heat exchange of air.
Owing to do not produce the interior obstruction of heat exchange stream that broken the end of a thread adheres to, remove filter so need not possess broken the end of a thread.Since do not possess broken the end of a thread filter, dry also good with flowing of air.
Washings side radiator 66 has the spiral radiator 550 of the washings that add type of thermal communication and wraps up the heat-insulating material 56 of radiating tube 550 from the outside.Interior all sides of spiral radiator 550 become the stream of the washings circulation that makes heating.The two ends of this stream are connected with suction side circulation pipe 64 communicatively with discharge side circulation pipe 67.
By the heat-insulating material 56 of washings side radiator 66, the heat of cold-producing medium does not drain to the outside, so the washings that circulate in the stream of washings side radiator 66 are heated well.
Other embodiment shown in Figure 8 below is described.
The main narration place different with the embodiment of Fig. 5, the common place common symbol of mark omits its explanation.
This embodiment, the periphery of bucket 2 bottom possesses radiator 53 outside, and the rear portion of bucket 2 possesses heat dump 52 outside.Heat dump 52 is configured in the position of also leaning on upside than the central axis at the center (central authorities) of passing through bucket 2.
Dry have internal path, the circulation canal 23a of air entry 2a, the heat dump 52 of the rear portion upside that is located at bucket 2, internal path, circulation canal 23b and the exhaust outlet 2b of radiator 53 with air flow path.
On washings inflow entrance 100, be provided with dry air check-valves 68.Dry air with check-valves 68 stop drying with air flow path in mobile drying go in the bucket 2 with air flow.Do not stop the washings in the bucket 2 to go out with the air flow path effluent on the contrary to drying.
Spray water nozzle 65 is located at the input port 11b upper lateral part of bucket 2.The direction of spray water nozzle 65 is towards the interior direction of the dry bucket 11 of washing, so spray water is sprayed on the washings 9 that is built in the dry bucket 11 of washing.
The spray water of spray water nozzle 65 is supplied with via spraying with tributary circuit 103 from the washings circulation flow path.Spray and be connected communicatively with the circulation canal 23b of washings circulation flow path with tributary circuit 103.On spraying, be provided with and spray with pump 120 with tributary circuit 103.
In dry operating, dry carry with Air Blast fan 24 and circulate in air flow path in the dry bucket 11 of washing, drying with air.By the circulation of this drying with air, the washings 9 in the dry bucket 11 of washing is dried.
When this dry operating, close exhaust channel 101 sides in the way with transfer valve 102, close washings inflow entrance 100 with dry air with check-valves 68, so do not produce drying, carry out drying well with leakage of air or short-circuit flow.
The outlet of exhaust channel 101 disposes in housing cabinet 1 in the way.The air-breathing drying that the drying that will carry out discharging with exhaust channel from the way 101 in bucket 2 offsets with air is located at the preceding upper lateral part of bucket 2 etc. with air inlet.Thus, make dryly with air exhaust channel 101 exhaust well from the way, the heat absorption of heat dump is carried out well.
The drying air that exhaust channel 101 is discharged from the way is the low air of humidity of sloughing moisture, so can in the housing cabinet water droplet not take place.
In the washing running, utilization sprinkling pump 120, dry barrel 11 interior washings of washing flow through the washings circulation flow path, sprinkling is sprayed on dry barrel 11 interior washings of washing from spray water nozzle 65 with tributary circuit 103.The part of washing water flowing in the circulation canal 23b of washings circulation flow path flows into the dry bucket 11 of washing from exhaust outlet 2b.
In the flowing of this washings, dry air is open with check-valves 68, so the circulation of washings is not carried out with having obstruction.
In when running washing, the drying that flows out from air entry 2a with air also from the way exhaust channel 101 discharge, so the heat absorption of heat dump 52 is compared during with dry operating and is inferior by no meansly carried out well., also carry out well thereupon,, can improve wash degree so can spray the good washings of heating with the heating of the washings of radiator 53.
