Washing machine according to present embodiment also comprises an operating unit 110, be used for the input service condition, such as washing, rinsing, dehydration or drying mode or time, with a control module 120, be used for based on the condition of work of utilizing operating unit 110 inputs the course of work of control motor 68, feed water valve 64B, heater 81, circulating fan 82, cooling water valve 87, circulating pump 94 and washings circulation control valve 95.
Below, the course of work to aforementioned washing machine at length is described.
Fig. 6 is a flow chart, shows a kind of method that is used to control according to the washing machine of first embodiment of the invention.
At first, after laundry item (m) was placed within the cylinder 70, door 56B was closed, and washing machine is started working.Then, this washing machine with functions/drying carries out work based on the work order by operating unit 110 inputs with washing, rinsing, dehydration or drying mode.
When selecting washing mode, control module 120 starts feed water valve 64B, and the washings in wash bucket 60 (w) reach the water level of a regulation, and the washings in wash bucket 60 (w) are closed feed water valve 64B (S1 and S2) when reaching this predetermined water level.
The washings (w) that feed is come by starting feed water valve 64B pass water supply hose 64C, detergent container 64D and water supply bellows 64E successively, and flow to the inside of wash bucket 60.A part of washings (w) in the wash bucket 60 are contained in the bellows drainpipe 91, and most of washings (w) are contained in the inside bottom of wash bucket 60.
Here, that part of washings (w) that are contained in the inside bottom of wash bucket 60 will pass opening 72 or pass through hole 74 on the cylinder 70, and flow to the inside of cylinder 70, soak laundry item (m) thus.
When termination supply washings (w) (described feed water valve is closed) were supplied with washings (w) afterwards or, control module 120 continued to open 68 1 sections official hours of motor (S3).
When motor 68 was activated, cylinder 70 was rotated, and laundry item (m) boosted under the effect of push pedal 76 and fall, and was washed thus.
When termination supply washings (w) (described feed water valve is closed) were supplied with washings (w) afterwards or, control module 120 continued heater 81 and 82 1 sections official hours of circulating fan (S4).
When heater 81 and circulating fan 82 are activated, air in cylinder 70 or the wash bucket 60 is subjected to the guiding of circulating fan 82, pass condensation pipe 84 and drying duct 83 successively, by heater 81 heating, and the front portion by cylinder 70 is recycled within the cylinder 70 subsequently.
When starting heater 81 and circulating fan 82, control module 120 continues 94 1 periods stipulated times of ON cycle pump, washings circulation control valve 95 is controlled, so that make this washings circulation control valve 95 carry out work (S5) with a kind of pattern in synchronous and the alternate mode.
Here, under synchronous mode, described drying device interface channel and cylinder spray passage to be opened simultaneously, thereby makes the washings of a part of institute pumping be passed the air heat of heater 81, and the washings of all the other institute's pumpings are sprayed to the inside of cylinder 70.On the other hand, under alternate mode, optionally open described drying device interface channel and cylinder at interval with official hour and spray passage, thereby make the washings of institute's pumping alternately be passed the air heat and the inside that is sprayed to cylinder 70 of heater 81.
If circulating pump 94 is activated and washings circulation control valve 95 carries out work under synchronous mode, washings (w) in the bellows drainpipe 91 will be pumped to shared flexible pipe 96 by circulating pump 94 so, and the washings (w) of institute's pumping will pass washings circulation control valve 95, and flow into drying device respectively and connect in the flexible pipe 97 and cylinder sprays in the flexible pipe 99.
That part of washings (w) that are directed to drying device connection flexible pipe 97 are sprayed to the rear portion of heater 81 by spreader nozzle 98, and the washings that spray (w) contact with the high temperature air that passes heater 81, be heated to form steam, be led to the front portion of cylinder 70 with described air, and soak the laundry item (m) in the cylinder 70, under the condition of high temperature, laundry item (m) is washed thus.
The remainder washings (w) that are led to cylinder sprinkling flexible pipe 99 pass spreader nozzle 100, be sprayed to the inside of cylinder 70, and bump with the laundry item (m) in the cylinder 70, improve washability thus, and soak laundry item (m) apace laundry item (m).
If circulating pump 94 is activated and washings circulation control valve 95 carries out work under alternate mode, washings (w) in the bellows drainpipe 91 will be pumped to shared flexible pipe 96 by circulating pump 94 so, and the washings (w) of institute's pumping alternately are pumped to, and drying device connects flexible pipe 97 and cylinder sprays flexible pipe 99.
When washings (w) were pumped to drying device connection flexible pipe 97, the washings (w) of institute's pumping were sprayed and are heated, and soak the laundry item (m) in the cylinder 70, under the condition of high temperature laundry item (m) are washed thus.When washings (w) were pumped to cylinder sprinkling flexible pipe 99, the washings (w) of institute's pumping were sprayed to the inside of cylinder 70, improve the washability to laundry item (m) thus, and soak laundry item (m) apace.
From starting heater 81 and circulating fan 82 and starting after circulating pump 94 begins through one period stipulated time, control module 120 is closed heater 81 and circulating fan 82, and closes circulating pump 94 (S6).
Begin through one period stipulated time from starter 68 after, control module 120 is closed motor 68 (S7).
After described washing machine with functions/drying was worked under aforementioned washing mode, dirty washings (w) remained in the inside bottom of wash bucket 60 and in bellows drainpipe 91 and the filter cartridge 93.These dirty washings (w) are disposed to the outside (S8) of washing machine.
After this, when selecting the rinsing pattern, in the mode identical with washing mode, control module 120 is supplied with washings (w), these washings (w) circulate, swing roller 70, and feed water valve 64B, motor 68, heater 81, circulating fan 82, circulating pump 94, washings circulation control valve 95 and draining valve 102 controlled, thus make and be disposed to the outside (S9 to S16) of washing machine owing to laundry item (m) being carried out washings (w) that rinsing makes dirty.
Here, in the mode identical with washing mode, the new washings (w) that are fed to wash bucket 60 inside are sprayed and are heated, under the condition of high temperature, the laundry item in the cylinder 70 (m) is carried out rinsing, perhaps be sprayed to the inside of cylinder 70, improve washability, and soak laundry item (w) apace laundry item (m).
