Certainly, can set request dry-cleaning operation after putting into clothing for.

Once you begin carry out dry-cleaning, washing agent feed unit 190 just is ejected into dry cleaning detergent on the clothing of putting into cylinder 130.

Preferably, the amount that is ejected into the washing agent in the cylinder 130 was not soaked clothing wherein.

Preferably, by 130 rotations of index drum when spraying dry cleaning detergent, and make dry cleaning detergent evenly cover on the whole clothing.

For this reason, cylinder 130 should rotate in one direction.Preferably, control alternately repeats swing roller 130 counterclockwise and clockwise.

In addition, by the chemical reaction that covers the dry cleaning detergent on the clothing various dirts are removed from clothing.

In said process, water heater 160 produces heat.

Correspondingly, concentrate on the water start vaporizer of the bottom of outer bucket 120, thereby in cylinder 130, produce steam.

For this reason, preferred water remains on clothing is put into cylinder 130 supply condition before.Preferably, water supplies to the bottom that water level does not flood cylinder 130.

The steam of above-mentioned generation impels the washing agent that is penetrated into clothing to work, thereby can remove dirt reposefully.

Certainly, preferably after finishing dry cleaning detergent injection and steam supply, time enough is set, makes it possible to from clothing, remove dirt reposefully.

After finishing above-mentioned a series of process, water is injected in the cylinder 130 by water supply pipe 112, thereby dirt is separated with clothing.

Can also prevent the dirt that separated pollution clothes once more like this with clothing.

For this reason, be injected into water in the cylinder 130 be preferably set to a spot of, not submergence clothing.

After finishing said process, to drying heater 143 supply of electrical energy, and drive blower fan 144, therefore can heat, dry air be supplied in the cylinder 130 with drying clothes by oven dry pipe 141.

After finishing the process of drying clothes, the operation of dry-cleaning pattern is promptly finished.

Simultaneously, owing to above-mentioned wash mill according to fifth embodiment of the invention produces steam by the water that evaporation supplies to outer bucket 120 bottoms, so water level should keep constant.

If water level is too high, the clothing in the cylinder 130 will be submerged, and this is worthless.If water level is too low, then be difficult to produce steam.

For overcoming this problem, provided the structure and the control method of the constant water level of the water that is used to keep to supply to outer barrel bottom by embodiments of the invention, describe below with reference to Figure 16 to Figure 19.

At first, the wash mill according to sixth embodiment of the invention comprises body 210, outer bucket 220, cylinder 230, water heater 260 and water supply pipe 212.

Body 210 forms the external form of wash mill.Inlet 211 is arranged on the front side of body 210.And opening 211 can be by door 215 opening/closings.

Outer bucket 220 is arranged in the body 210, and cylinder 230 rotatably is arranged in the outer bucket 220.

Periphery at cylinder 230 is provided with a plurality of perforation 231 that make water and steam flow into cylinder 230.

Bucket 220 inner bottom parts are provided with the water heater 260 that is used to heat the water that supplies to outer bucket 220 outside.

At this moment, also the recess of bucket 220 is provided with the part 221 (hereinafter referred to as loading part) of loading water heater 260 outside, and this loading part links to each other with drainpipe 223, is used for after washing finishes water being discharged.In addition, drainpipe 223 is provided with draining valve 225.

Especially, water heater 260 can produce steam and add hot water.

That is to say, in an embodiment according to the present invention, can utilize water heater 260 rather than produce the steam of cleaning clothes with independent steam generator.

Water supply pipe 212 is pipelines of current process.Water supply pipe 212 is transported to the water of feed pipe or other similar supply pipe supply in the outer bucket 220 by feed water valve 217.

At this moment, the detergent box 219 that is used for storing detergent is arranged on the pipeline of water supply pipe 212, like this, just washing agent can be added in the water that flows into outer bucket 220.

Detergent box 219 is arranged in the upper space in the body 210, so that can put into washing agent.

In the prior art, the delivery port that supplies water to the water supply pipe 212 that water heater 260 parts are housed is connected with the top of outer bucket 220, thus the water-soaked that the clothing that will dry-clean may be supplied to.Thereby need address this problem.

Preferably, water supply pipe 212 is connected near the part that is provided with water heater 260 is loading part 221 with outer bucket 220.

At this moment, as shown in figure 17, the delivery port of water supply pipe 212 preferably is connected with the lower circumference face of outer bucket 220.

When its purpose was to prevent outside supplying water to by water supply pipe 212 bucket 220, water was splashed on the periphery of cylinder 230.

Preferably, the delivery port of water supply pipe 212 is bent upwards from its underpart as shown in the figure to prevent that water from splashing out.

Preferably, the water level of the outer bucket 220 interior loading parts 221 of supply is set to be no more than the bottom of cylinder 230.

If water level surpasses the bottom of cylinder 230, water may soak clothing by being formed in the perforation inflow cylinder 230 on cylinder 230 outer peripheral faces.

Preferably, also be provided with the water level that a series of structure detection is supplied with the water of outer bucket 220.

The invention is characterized in and also comprise a level sensing unit that is arranged on lower space in the outer bucket 220.

The water level of level sensing unit sensing in loading part 221, with control feed water valve 217 and water heater 260, thereby the water level that can remain in the loading part is constant.

Level sensing unit can comprise the pressure sensor that is generally used for water level detecting.But, consider that to be used to dry-clean the water yield of the operation water yield more required than common cleaning little, it is disadvantageous therefore using the pressure sensor with big relatively water quantity delivered deviation.

Preferably, sensing unit comprises temperature sensor 251, detects whether supply with water by detecting environment temperature.

At this moment, it is higher and lower than the position of cylinder 230 than the position of water heater 260 temperature sensor 251 preferably to be set.

Because water heater 260 has only when submerging under water and just can produce heat, can prevent that therefore water heater 260 from producing excessive heat.

Preferably, temperature sensor 251 is arranged between the bottom of water heater 260 and cylinder 230, thereby apart from water heater 260 farthest.

This structure can make the heat that produces owing to water heater 260 make temperature sensor 251 accurately the problem of sensing temperature minimize.

Following flowchart text with reference to accompanying drawing 19 is according to the control method of the above-mentioned wash mill of sixth embodiment of the invention.

At first, the controller (not shown) of index drum formula washing machine operation constantly detects and whether has dry-cleaning operation requests (S110).

That is to say that when the operation of customer requirements roller washing machine was controlled, controller determined that user-selected operation is that dry-cleaning or normal laundry are cleaned.Therefore, controller can detect the existence of dry-cleaning request.

At this moment, when having the dry-cleaning operation requests, the clothing that will dry-clean is put in the controller request.

At this moment, the clothing that the user will dry-clean is put into cylinder 230, closes to call 215, then selects to carry out continuously and dry-cleans operation.

Certainly the user can require the dry-cleaning operation after putting into clothing, thereby controller can be controlled each parts that are used to dry-clean operation rapidly.

Afterwards, when finishing the dry-cleaning preparation through aforementioned a series of program, controller (not shown) control feed water valve 217 is supplied with (S120) in the water supply pipe 212 with water.

Therefore, water can be joined in the outer bucket 220 by water supply pipe 212.At this moment, because the delivery port of water supply pipe 212 is positioned at outer bucket 220 belows, thereby can prevent that sealing is directly injected to the outside of cylinder 230.Therefore, can prevent the clothing of getting wet.

As previously mentioned, the water of supplying with outer bucket 220 enters into the loading part 221 that is provided with water heater 260, and little by little the original state from Figure 17 rises to the top of loading part 221.At this moment, cut off the pipeline of the drainpipe 223 that is connected to loading part 221.

In the process that supplies water, controller constantly receives the signal of the temperature variation that temperature sensor 251 sends, and has surpassed reference temperature value (S130) with the variable quantity that detects the transient temperature that whether senses.

Reference temperature value is that instantaneous and abrupt temp changes the value that produces herein, rather than increases the uniform temperature value added of proportional variation with temperature.Reference temperature value can be set to ± 2 ℃ or similar value.

For example, suppose that water temperature is about 15 ℃, temperature sensor 251 carries out temperature sensing when environment temperature is about 30 ℃.If the water of supplying with arrives temperature sensor 251, temperature sensor 251 has just detected the temperature drop-out value when measuring water temperature.In this way, can detect current water level.

When detecting water level and arrived required water level, controller control feed water valve 217 stops to supply water state as shown in figure 18.

Therefore can prevent that water from flowing in the cylinder 230.

Afterwards, feed-water heater 260 power supplies (S140), dry-cleaning then generates heat by heater 260 with vapours and produces.

That is to say that the generation heat of water heater 260 makes the water evaporation in the outer bucket 220.The steam that is produced by evaporation 231 enters into the clothing of cylinder 230 with washing barrel 230 by boring a hole.

At this moment, cylinder 230 constantly rotates to stir the clothing in the cylinder 230, makes cleaning clothes more smooth.

Be created in to clean to be provided with in the time according to the steam of said process and constantly take place.If the time of the dry-cleaning time ratio of the setting whole evaporations of water of bucket 220 bottoms outward is long, the shortage of water will soon take place, thereby the temperature of water heater 260 place parts is raise rapidly.

Certainly, the dry-cleaning time of setting also can be shorter than the evaporation of water time.At this moment, thus the quantity of steam that is used to dry-clean may reduce and makes the dry-cleaning weak effect.Also can pass through to change the shape of loading part 221 in the outer bucket 220 to increase the amount of storage of water.At this moment, change shape and need redesign other parts.

Therefore, in an embodiment according to the present invention, when producing steam, utilize temperature sensor 251 to supply with the preliminary phase continuous sensing temperature of mode together to detect overheated generation (S150) with water.

That is to say,, just can determine lack of water when temperature sensor 251 when temperature raises suddenly in the process of detected temperatures changing value.Therefore, supply with the loading part 221 (S160) at water heater 260 places in the outer bucket 220 with adding water in addition.

Certainly, the time point that preferably stops to supply water in water supply process again changes to determine by detected temperatures, to prevent to supply with the excessive clothing that soaks of water.

If the quantity delivered of the steam of dry-cleaning usefulness is defined as abundance in aforementioned a series of processes, then cut off the power supply (S170) of water heater 260.

At this moment, the quantity of steam that produces with water heater 260 hot generation times obtains in advance by test or other similar approach, set in advance the value that is obtained, the process of like this can be this simply the time of water heater 260 and similar 's generation heat being carried out timing is determined quantity of steam.

That is to say,, just need to cut off the power supply of water heater 260 if timing has arrived setting-up time.

Certainly, the inside of bucket 220 is provided with the humidity sensor (not shown) that detects the quantity of steam in the outer bucket 220 outside, thereby if the detected humidity of humidity sensor reaches the power supply that predetermined humidity is just cut off water heater 260.

Finish after the dry-cleaning by aforementioned process, thereby control draining valve 225 is opened drainpipe 223 water remaining in the loading part 221 is all discharged (S180).So just finish the dry-cleaning operation.

Simultaneously, be characterised in that according to the wash mill of seventh embodiment of the invention and used electrode sensor rather than use, below it is elaborated according to the temperature sensor in the sixth embodiment of the invention.

At first, according to wash mill such as Figure 20 and shown in Figure 21 of seventh embodiment of the invention, comprise body 210, outer bucket 220, cylinder 230, water heater 260, water supply pipe 212, electrode sensor and controller.

At this moment, the structure of body 210, outer bucket 220, cylinder 230, water heater 260 and water supply pipe 212 is with identical according to the structure in the sixth embodiment of the invention.

Electrode sensor comprises first electrode 252 and second electrode 253.

The effect of first electrode 252 and second electrode 253 is the water level of the outer bucket of sensing supply 220 inner bottom parts, avoids surpassing the bottom of cylinder 230, and two electrodes are arranged between water heater 260 and the cylinder 230.

That is to say, first electrode 252 be arranged on water heater 260 near, second electrode 253 is arranged on the top of first electrode 252.Therefore, when water level has surpassed the water level of setting, can between first electrode 252 and second electrode 253, form electric current.

Preferably, when between first electrode 252 and second electrode 253, forming electric current, feed water valve 225 and water heater 260 are controlled.

Particularly, first electrode 252 is preferably placed at water heater 260 tops, and second electrode 253 is preferably placed at the below, bottom of cylinder 230.

Be in the space, water heater 260 place in a relative position of another position that links to each other with the delivery port of water supply pipe 212 and be provided with electrode sensor.Therefore, supply with before water arrives predetermined water level finishing, when the water short circuit of

electrode

252 and 253 by spilling, can prevent to drive the fault that water heater 260 produces heat.

That is to say, just can not produce heat, thereby can prevent that water heater 260 from producing excessive heat owing to water heater 260 has only when having in the entry fully.

By detecting between first electrode 252 and second electrode 253 whether have short circuit, the controller (not shown) plays the effect of the heat generation of control water heater 260.

Also comprise according to embodiments of the invention and to be arranged on outer bucket 220 humidity inside sensors 254.

Humidity sensor 254 detects the bucket 220 interior quantity of steams that produce outside, with control water heater 260, thereby by keeping appropriate humidity can improve the cleaning performance of clothing.

The control method of following flowchart text above-mentioned wash mill according to a seventh embodiment of the invention with reference to Figure 22.

At first whether the continuous detection of controller (not shown) of index drum formula washing machine operation exists dry-cleaning operation requests (S210).

That is to say that when the operation of customer requirements tumbling-box washing machine was controlled, controller determined that user-selected operation is that dry-cleaning or normal laundry are cleaned.Therefore, controller can detect and whether have the dry-cleaning request.

When having the dry-cleaning operation requests, the clothing that will dry-clean is put in the controller request.

Certainly the user can require the dry-cleaning operation after putting into clothing, thereby controller can be controlled each parts that are used to dry-clean operation immediately.

Afterwards, when finishing the dry-cleaning preparation through aforementioned a series of program, controller control feed water valve 217 is supplied with (S220) in the water supply pipe 212 with water.

Therefore, water can be joined in the outer bucket 220 by water supply pipe 212.At this moment, because the delivery port of water supply pipe 212 is positioned at outer bucket 220 belows, can prevent that sealing directly injects the outside of cylinder 230.Therefore, can prevent the clothing of getting wet.

As previously mentioned, the water of supplying with outer bucket 220 be added into be provided with water heater 260 loading part 221 to be elevated to the top of loading part 221 at leisure.At this moment, cut off the pipe passage of the drainpipe 223 that is connected to loading part 221.

In the process that supplies water, controller constantly detects whether there is short circuit (S230) between

electrode

252 and 253.

At this moment, when supply water water level constantly increased, as shown in figure 20, water level arrived first electrode 252.When continuous supply water, water level exceeds first electrode 252 and arrives second electrode 253.

At this moment, first electrode 252 and second electrode 253 form short circuit.Therefore, controller determines that water level arrives essential water level, then controls feed water valve 217 and stops to supply water.

Therefore, can prevent that water from flowing in the cylinder 230.

Then, controller makes feed-water heater 260 power (S240), thereby can be generated the vapours of dry-cleaning usefulness by the heat that water heater 260 produces.

That is to say that the generation heat of water heater 260 makes the water evaporation in the outer bucket 220.Be incorporated in the cylinder 230 with the clothing in the washing barrel 230 by the perforation 231 of the steam that evaporates generation by cylinder 230.

That is to say that the generation heat of water heater 260 makes the water evaporation in the outer bucket 220.The steam that is produced by evaporation 231 joins cylinder 230 with the clothing in the washing barrel 230 by boring a hole.

At this moment, cylinder 230 constantly rotates to stir the clothing in the cylinder 230, and the effect of cleaning clothes is improved.

Steam according to said process is created in constantly generation in the washing setting-up time.If the water that the dry-cleaning time ratio of setting will outer bucket 220 bottoms all required time of evaporation long, the shortage of water will soon take place, thereby the temperature of water heater 260 place parts is raise rapidly.

Certainly, the dry-cleaning time of setting also can be shorter than the evaporation of water time.At this moment, thus the quantity of steam that is used to dry-clean may reduce and makes the dry-cleaning weak effect.Also can increase the amount of storage of water by the shape that changes the loading part 221 in the bucket 220 outside.At this moment, change shape and need redesign other parts.

Therefore, preferably, when producing steam, with and water supply with preliminary phase with mode constantly detect between electrode, whether there is short circuit (S250).

That is to say,, just can determine lack of water when detecting when between electrode, having short circuit.Therefore, in addition water is supplied with the loading part 221 (S260) at water heater 260 places in the outer bucket 220.

Certainly, whether the time point that stops to supply water in water supply process again preferably exists short circuit to determine between electrode by continuous detection, and then it is excessive and soak clothing to prevent to supply with water.

If in a series of aforementioned process dry-cleaning be defined as with the quantity delivered of steam sufficient, the power supply (S270) of cut-out water heater 260.

At this moment, quantity of steam can be determined by the sensing value that is arranged on the humidity sensor 254 in the outer bucket 220.

That is to say, when the humidity that constantly detects in outer barrel 220,, just cut off the power supply of heater 260 if humidity has reached predetermined moisture.

At this moment, predetermined moisture is meant the most suitable cleaning clothes of quantity of steam, and predetermined moisture can obtain by the detected value of no any qualification.

Alternatively, the quantity of steam that produces with water heater 260 hot generation times can obtain in advance by test or other similar approach, set in advance the value that is obtained, can determine quantity of steam by resembling such simple procedure that water heater 260 and similar 's the hot rise time is carried out timing like this.

That is to say,, just need to cut off the power supply of water heater 260 if determine to have arrived setting-up time by timing.

Finish after the dry-cleaning by aforementioned process, thereby control draining valve 225 is opened drainpipe 223 water remaining in the loading part 221 is all discharged (S280).So just finish the dry-cleaning operation.

Simultaneously, preferably supply with water supply pipe, therefore be difficult to keep water level accurately owing in the 5th to the 7th embodiment according to the present invention, be used to generate the water of steam.

That is to say that amount of makeup water seldom.But amount of makeup water also may be excessive.
