The washing machine 100 of one embodiment of the invention washing machine for wash, rinsing or dehydration and can carry out the process whether washing machine freezes that detects after moving.

The washing machine 100 of one embodiment of the invention is judged by following whether freezing several times can correctly judge whether freezing of washing machine, above-mentioned whether freeze several times to judge refer to: by whether freezing to judge the first time that a series of flow processs shown in Fig. 9 a are carried out, in a series of flow processs shown in above-mentioned Fig. 9 a, after applying voltage to washing machine, water level and the first designated water level in the water jacket 2 are compared, judge whether to have occured to overflow, and carry out draining according to judged result; By whether freezing to judge the second time that a series of flow processs shown in Fig. 9 b are carried out, in a series of flow processs shown in above-mentioned Fig. 9 b, water level and the second designated water level in the water jacket 2 are compared, and the water level in the water jacket 2 is carried out draining in the situation more than the second designated water level; And judging by whether freezing for the third time of carrying out of a series of flow processs shown in Fig. 9 c in order to carry out the strokes such as washing, rinsing and dehydration and after water jacket 2 interior supply washings.

Below, with reference to Fig. 9 a, the concrete deterministic process of whether freezing for the first time of observing.

Apply power supply, washing machine is brought into operation after (step S901), the water level that detects in the water jackets 2 by level sensor 20, and detected value and the first designated water level that detection obtains compared, judge whether (step S902) has occured in the water jacket 2 to overflow.The reason of carrying out these processes is, whether detects before the washing machine operation that the washings that cause because of special circumstances water jacket 2 in overflow and whether the water yield overflows from water jacket 2 above the regulation level.For example can enumerate following situation, that is, at feed water valve 6 abnormals, under the state of the power-off of washing machine, still continue to the situation of water jacket 2 interior supply washings.Therefore preferably, consider to cause the water level that washings overflow from water jacket 2 to set the first designated water level.

If the water level that is judged as in step S902 in the water jacket 2 is higher than the first designated water level, control part 14 just makes display part 22 output the 3rd error messages (step S903).The 3rd error message is to allow the user identify to have occured to overflow and the information exported.

Afterwards, control part 14 makes draining pump 10 move the washings (step S904) of discharging in the water jacket 2, water level in the water jacket 2 is lower than in the situation (step S905) of the second designated water level within the predetermined time, to close (OFF) the 3rd error message (step S906), preferably, the empty water level settings that will all discharge state as the washings in the water jacket 2 is that the second designated water level should.Below, describe take the situation of the second designated water level as the sky water level.

On the other hand, in step S905, water level in the water jacket 2 fails to reach in the situation of the second designated water level, draining pump 10 will continue operation, until water discharge time is through the first draining setting-up time, water level in the water jacket 2 fails to reach in the situation (step S907) of the second designated water level, control part 14 will compare (step S908) by temperature and the first fiducial temperature that temperature sensor 18 detects, its result, if being judged as detected said temperature, to be lower than the first fiducial temperature low, just show the first error message by display part, if be judged as above-mentioned the first fiducial temperature height that is higher than of detected temperature, just by display part 22 output the second error message or the 3rd error messages (step S910).

Below, with reference to Fig. 9 b, the concrete deterministic process of whether freezing for the second time of observing.

Whether freeze for the second time deterministic process and be to carry out under the condition that water level in water jacket 2 is lower than the first designated water level.Namely, be lower than in the low situation of the first designated water level in order in step S902, to be judged as the water level that detects by level sensor 20, or be lower than in the situation of the second designated water level through the water levels in the water jacket 2 behind step S902, step S903, step S904, step S905, the step S906, after be used for judgement in the process carried out and whether freeze.

Whether second freeze the step (step S911) that deterministic process comprises that the temperature that will detect by temperature sensor 18 and the second fiducial temperature compare.In step S911, the said temperature that detects is in the situation below the second fiducial temperature, and control part 14 control display sections 22 export the first error messages (step S912).

Water jacket 2 interior water levels might be in (situation that might occur when directly entering into step S911 after step S902) below the first designated water level or below the second designated water level in step S911 (for example the water level in the water jacket 2 becomes the situation of sky water level after successively execution in step S902, step S903, step S904, step S905 and step S906).Water level in the water jacket 2 is higher than the second designated water level and is lower than in the situation of the first designated water level, and temperature sensor 18 detects the temperature of the washings in the water jacket 2.On the contrary, the water level in the water jacket 2 is lower than in the situation (for example, empty water level) of the second designated water level, the temperature of the air of the inside of temperature sensor 18 detection washing machines.Consider the problem that washings freeze, be preferably sub-zero value is set as the second fiducial temperature, consider the situation that detects air themperature by temperature sensor 18, also the value below the subzero water degree can be set as the second fiducial temperature.

In step S911, be judged as in the situation that the temperature that detects by temperature sensor 18 is lower than the second fiducial temperature, the temperature of inside that control part 14 just is judged as washing machine is fully low, and reached the degree that can fully freeze, directly by display part 22 output the first error messages (step S912).With regard to the execution by step S911 and step S912 whether freeze detect with regard to, with the draining characteristics of washings irrespectively, only the detected value according to temperature sensor 18 is according to judging or predicting and whether freeze, be not limited to the order shown in Fig. 9 b, can carry out any time in the washing machine running.

Particularly, in step S911, be preferably and by experiment suitable value be set as second and set temperature, can freezing with structure member such as the feed water valve 6 of the pre-settled temperature washing machine in the situation below the second design temperature that detects by temperature sensor 18 of sufficient correctness or draining pump 10 etc.

On the other hand, be judged as the temperature that detects by temperature sensor 18 and be higher than the second fiducial temperature in step S911, control part 14 will compare (step S913) by water level and the 3rd designated water level that level sensor 20 detects.

The above-mentioned water level that detects is higher than and refers in the situation of the 3rd designated water level that the interior water level that exists of water jacket 2 is more than the 3rd water level and the washings below the first designated water level, in the case, control part 14 operation draining pumps 10 are carried out draining (step S915), after in the second draining setting-up time, carrying out draining, if the change value (step S916) more than a reference value of the water level in the water jacket 2, just be judged as and carrying out normal draining, and the amount (step S914) of detection washings, on step S916, even establish the time (step S917) if passed through the second draining, the fluctuation of water table value is also still below a reference value, then will compare (step S918) by temperature and the 3rd fiducial temperature that temperature sensor 18 detects, be lower than at the said temperature that detects in the situation of the 3rd fiducial temperature, 22 output the first error messages (step S919) of control part 14 control display sections, the said temperature that detects is higher than in the situation of the 3rd fiducial temperature, 22 output the second error messages (step S920) of control part 14 control display sections.Whether freezing for the third time deterministic process can carry out under the condition below the 3rd designated water level by the water level in water jacket 2, and can carry out afterwards at the detecting step (step S914) of the amount of the washings shown in Fig. 9 b.

In step S914, if detect the amount of the washings in the inside groove 6, the pattern of each strokes such as the washing that will carry out after just setting according to the amount of the washings that detects, rinsing, dehydration.

In the water supply step (step S921), to water jacket 2 interior supply washings, at this moment, the amount of the washings of supplying with is also set according to the amount of the washings that detects in step S914.

In step S921 behind the water supply start, if through the first water supply setting-up time (step S922), just carry out the step (step S923) that the water level in the water jacket 2 and the first water supply designated water level are compared, whether normally carry out to judge to supply water, if the water level that detects by level sensor 20 is more than the first water supply designated water level, control part 14 just is judged as and supplies water normally, again water level and the second water supply designated water levels in the water jacket 2 is compared (step S928) through (step S924) behind the second water supply setting-up time.At this, when referring in the first water supply setting-up time normal water supply, estimates the first water supply designated water level the water level that reaches, the second water supply designated water level refers to will be to the target water level of water jacket 2 interior supplies according to the amount of the washings that detects in step S914.

On the other hand, if the water level that is judged as in step S923 in the water jacket 2 fails to reach the first water supply designated water level, control part 14 just will compare (step S925) by temperature and the 4th fiducial temperature that temperature sensor 18 detects, comparative result, the said temperature that detects is lower than in the situation of the 4th fiducial temperature, and control display section 22 shows the first error message, and is opposite, the said temperature that detects is higher than in the situation of the 4th fiducial temperature, exports the 4th error message.At this, the 4th error message be to the user inform because of feed water valve 6 grades break down can't normal water supply information.

On the other hand, even the water level that detects by level sensor 20 in step S928 fails to reach in the situation of the second water supply designated water level, control part 14 also can control display section 22 show the 4th error message (step S929).

On the contrary, if the water level that detects by level sensor 20 in step S928 is higher than the second water supply designated water level, the situation that just belongs to normal water supply, afterwards, control part 14 is carried out washing stroke by predetermined algorithm through washings (step S911), for the second time washing (step S932) and draining (step S933) that for the first time washing (step S930), operation heater 28 heat in the water jacket 2.At this, when carrying out the above-mentioned washing first time (step S930), for the second time washing (step S932), inside groove 6 and/or impeller 4 rotations, and by draining pump 10 drainings (step S933).

After draining (step S933) time reaches the 3rd draining setting-up time (step S929), the water level in the water jacket 2 also fails to reach in the situation of draining end water level, and control part 14 control display sections 22 show the second error messages (step S940).On the contrary, if be to be judged as water level in the water jacket 2 below draining finishes water level at step S934, the situation that just belongs to normal draining, afterwards, after carrying out rinsing (step S935), simple dehydration (step S936), formal dehydration (step S937) etc., the power-off of washing machine (OFF) (step S935), thus washing machine finishes operation.

With reference to Figure 10, the washing machine of present embodiment comprises the first power suppling part 24 and second source supply unit 26.

Do not wash at washing machine, rinsing or dehydration and be in the situation of holding state, the first power suppling part 24 is supplied with the following power supply of pre-sizing, power supply by being supplied with by the first power suppling part 24 also can move display part 22 under the washing machine holding state.

Second source supply unit 26 can be supplied with the above power supply of above-mentioned pre-sizing, and supplies with the required power supply of operation feed water valve 6, draining valve 8 and draining pump 10.On the other hand, when washing, rinsing or dehydration, can be by second source supply unit 26 to drive division 13 power supplies.

In the washing machine of present embodiment, do not wash at washing machine, rinsing or dehydration and be in the situation of holding state, for freezing of the various structure members that prevent from consisting of washing machine, by temperature sensor 18 detected temperatures, when the said temperature that detects is lower than design temperature, operation consists of the various structure members of washing machine, and what occur when moving by the said structure parts prevents from freezing from heat release.

On the other hand, although the power supply to temperature sensor 18 and heater 28 supplies can be by the some supplies in the first power suppling part 24 or the second source supply unit 26, but preferably, do not wash at washing machine, rinsing or dehydration and be in the situation of holding state, provide power supply by the first power suppling part 24 to temperature sensor 18, and be lower than in the temperature that temperature sensor 18 detects in the situation of design temperature, supply with the required power supply of operation heaters 28, feed water valve 6, draining valve 10 or draining pump 10 by second source supply unit 26.Washing machine is in the situation of holding state, has the effect that can reduce the electric weight that consumes by temperature sensor 18.

The second, as shown in figure 10, washing machine has can select antifreeze antifreeze selection portion 16, only in the situation that the user has been undertaken by antifreeze selection portion 16 selecting, just begins antifreeze.

Figure 11 described later can adopt in above-mentioned two kinds any one to antifreeze beginning (step S1101, step S1201, step S1301, step S1401, step S1501, step S1601, step S1701, step S1801) shown in Figure 180.

And temperature sensor 18 of the present invention can be arranged at some in feed water valve 6, draining valve 8 or the draining pump 10, and is described in more detail in embodiment described later.

Below, with reference to Figure 11 to Figure 18, the embodiment of the means to prevent freezing of feed water valve 6 is described.But the means to prevent freezing shown in Figure 11 to Figure 18 is tried out antifreeze in draining valve 8 equally, and difference is in the case, and temperature sensor 18 is arranged at draining valve 10, and determines whether moving draining valve 10 according to the detected value of temperature sensor 18.

Figure 11 is the precedence diagram of control method of the washing machine of the expression sixth embodiment of the present invention.In the present embodiment, temperature sensor 18 is arranged on the feed water valve 6.

If antifreeze beginning (step S1101), just by temperature sensor 18 detected temperatures (step S1102), it is low that the temperature that detects by temperature sensor 18 is lower than design temperature, feed water valve 6 operations (step S1103, step S1104).After feed water valve 6 operations, as long as do not remove antifreeze, temperature sensor 18 is detected temperatures (step S1106) repeatedly just, the temperature that again detects by temperature sensor 18 when above-mentioned design temperature is above, feed water valve 6 stop running (step S1107, step S1108).Afterwards, freeze (step S1105) according to detecting whether again to have removed, by temperature sensor 18 detected temperatures (step S1106), when the temperature that detects was lower than above-mentioned design temperature, feed water valve 6 reruned (step S1103, step S1104).

As mentioned above, according to the temperature that detects by temperature sensor 18, feed water valve 6 repeatedly moves (step S1104) and ends (step S1108), last till remove antifreeze till.At this, remove above-mentioned antifreeze condition and be that the 16 input contact commands of user by selecting section or user's input are used for washing, the control instruction of rinsing or dehydration.

In the present embodiment, temperature sensor 18 is arranged on the feed water valve 6.

At this, the interval for draining pump 10 does not move is called in step S1804 " termination ", and is called " stopping " in step S1808, and this is because step S1804 and step S1808 have difference in the method for operation of draining pump 10.That is, in step S1804, draining pump 10 repeatedly moves in the given time and ends, on the contrary, draining pump 10 out of service in step S1808 turns back to step S1802 from step S1809, is in holding state before reruning in step S1804, and can not moves.

On the other hand, remove in step S1809 that antifreeze condition is that the 16 input contact commands of user by selecting section or user's input are used for washing, the control instruction of rinsing or dehydration.

More than among the viewed embodiment, the heat that produces when utilizing the electronic unit operation that consists of washing machine prevents freezing of washing machine, particularly, prevents from freezing because of feed water valve 6, draining valve 8 or the draining pump 10 that remaining water may frequent occurrence freezes by operation.

With reference to Figure 19, the control method of the washing machine of fourteenth embodiment of the invention detected the water level (step S1901) in the water jacket 2 before supplying with washings.In step S1901, by level sensor 20 sensed water level.

Water level and designated water level that control part 14 will detect in step S1901 compare (step S1902), be lower than in the low situation of designated water level at the above-mentioned water level that detects, supply water, carry out afterwards the strokes (step S1903) such as washing, rinsing and dehydration.In step S1903, control part 14 control feed water valves 6 make its water supply.

On the other hand, the water level that detects in step S1902 is higher than in the situation of designated water level, and control part 14 operation draining pumps 10 make it discharge washings (step S1904).Afterwards, by the water level in the level sensor 20 continuation detection water jackets 2, in the situation that water level before through the draining setting-up time in the water jacket 2 fully reduces (step S1905), the open feed water valve 6 of control part, with to water jacket 2 interior supply washings, and carry out the strokes (step S1903) such as washing, rinsing and dehydration.

On the contrary, in step S1905, water levels in the water jacket 2 fail fully to reduce and during through the draining setting-up time, control part 14 is by temperature sensor 18 detected temperatures (step S6), after temperature and the fiducial temperature that detects compared (step S1907), be lower than at the said temperature that detects in the situation of fiducial temperature, by display part 22 output the first error messages (step S1908), be higher than at the said temperature that detects in the situation of fiducial temperature, by display part 22 output the second error messages (step S1909).

On the other hand, in step S1904, through also failing the situation (step S1905) of abundant draining after the draining setting-up time, can be assumed to be because freezing a kind of in the situation (exporting the first error message) of normally draining or the situation (exporting the second error message) that draining pump 10 breaks down in the Drainage Division that comprises draining stream 9, draining pump 10 and/or draining valve 8.

Step S1906 is used for the identification above-mentioned two situations to step S1907 any situation has occured, be lower than fiducial temperature if in step S1907, be judged as the temperature that in step S1906, detects, just can think and move under the washing machine environmental condition that equitemperature is low in the winter time, control part 14 is by display part 22 outputs the first error message, occured to freeze to allow the user identify above-mentioned Drainage Division.The said reference temperature is as the value of setting by experiment, is can dope with suitable correctness the value freezed has occured in the situation that has remaining water in the washing machine.Preferably, sub-zero value is set as the said reference temperature.

On the contrary, can say and in step S1907, be judged as the temperature that in step S1906, detects to be higher than the high situation of fiducial temperature be the low-down situation of possibility that the remaining water in the washing machine freezes, therefore, it is the obstruction etc. of fault, draining stream 9 or the draining valve 8 of draining pump 10 that control part 14 hypothesis causes the reason of fully draining, and 22 outputs the second error message of control display section, to allow the user identify.

On the other hand, in the present embodiment, why in the running of washing machine before supplying water execution in step S1902, because in order to wash or rinsing and before supplying water in the interior situation that has washings of water jacket 2, whether utilize this to judge freezes, and detect when having occured to freeze, do not supply with washings, prevent in advance unnecessary water supply effect thereby play.

Preferably, control part 14 stops running washing machine when being controlled in step S1908 or step S1909 the corresponding error message of output, and with the output of user's specific operation or above-mentioned error message as condition subsequent, carry out remaining process.

With reference to Figure 20, apply power supply to washing machine, it is brought into operation after, before water jacket 2 interior water supply, by temperature sensor 18 detected temperatures (step S2001).

Temperature T and fiducial temperature T1 that control part 14 will detect in step S2001 compare (step S2002).At this, sub-zero value can be set as fiducial temperature (step S2001).

Be lower than fiducial temperature T1 if be judged as the temperature T that in step S2001, detects, namely, the temperature of the air that detects by temperature sensor 18 can be considered washing machine in subzero situation and freezes to move under the dangerous condition in existence, therefore, after a plurality of steps (step S2011 step S2018) in judge whether freezing of washing machine.

On the contrary, be higher than fiducial temperature T1 if be judged as the temperature T that in step S2001, detects, just after a plurality of steps (step S2021 is to step S2030) in judge whether normally operation of feed water valve 12 or draining pump 10, these processes and judge step S2011 that whether washing machine freeze to step S2018 be distinguishing.

At first, the detected value T that is judged as temperature sensor 18 in step S2002 is lower than in the situation of fiducial temperature T1, detect the amount of washings, put the amount (step S2011) of the washings in the inside groove 3 into detection, according to the amount target setting water level of the washings that detects, and to water jacket 2 interior water supply (step S2012).

Afterwards, by the water level that level sensor 20 detects in the water jacket 2, control part 14 judges whether the detected value W of level sensor 20 reaches the first designated water level W1(step S2013 in predefined the first setting-up time).At this, the value lower than the target water level of setting according to the amount of washings can be set as the first designated water level W1 in step S2011.

At this, can be set as above-mentioned the first setting-up time with reaching the required short value of time of target water level of in step S2011, setting than the water level in the water jacket 2 under the condition of feed water valve 12 normal operations.

Water level detecting value W fails to reach in the situation of the first designated water level W1, and control part 14 can be judged as fails normal water supply, interrupts and make to supply water, and makes washing machine (step S2017) out of service, and makes display part 22 show the 5th error messages (step S2018).Above-mentioned the 5th error message is used for informing because freezing to cause washing machine normally to move.

On the other hand, be judged as in step S2013 that water level detecting value W reaches in the situation of the first designated water level W1 in above-mentioned the first setting-up time, carry out washing (step S2014).Washing (step S2014) is a kind of process that makes impeller 4 or inside groove 3 rotations remove the spot on the washings, and the rotary mode of impeller 4 and inside groove 3 can diversely arrange.

Draining (step S2015) is the complete rear process that washings in the water jacket 2 are discharged to the outside of a kind of washing (step S2014), is undertaken by draining pump 10.During draining (step S2015), control part 14 operation draining pumps 10.

In the process of draining (step S2015), by the water level in the level sensor 20 detection water jackets 2, after implementing draining (step S2015), whether the water level of control part 14 in judging water jacket 2 has dropped in the second setting-up time below the second designated water level W2 (step S2016).

The situation that the detected value W that is judged as level sensor 20 in step S2016 is higher than the second designated water level W2 is to fail the situation of normally carrying out by the draining that draining pump 10 carries out, the reason that causes this result probably is because draining pump 10 has occured to freeze, therefore, control part 14 interrupts draining, make washing machine (step S2017) out of service, and make display part 22 show above-mentioned the 5th error message (step S2018).

The detected value that is judged as level sensor 20 in step S2016 is lower than in the situation of the second designated water level W2, again to water jacket 2 interior water supply, and carry out successively the rinsing washings rinsing (step S2003), make inside groove 3 high-speed rotaries transfer the dehydration (step S2004) that dries washings.

On the other hand, when the detected value T that is judged as temperature sensor 18 in step S2102 is higher than in the situation of fiducial temperature T1, but execution in step S2021 is to step S2030.Step S2021 is basically identical to step S2016 with step S2011 to step S2026, but the detected value W at step S2023 middle water level sensor 20 is lower than in the situation of the first designated water level W1, control part 14 is judged as fails normal water supply, interrupt and make to supply water, make washing machine (step S2027) out of service, and make display part 22 show the 6th error message (step S2028).Above-mentioned the 6th error message is used for informing that feed water valve 12 fails normal operation.

And, it is that the situation of normally carrying out is failed in draining that the detected value W that is judged as level sensor 20 in step S2026 is higher than the second designated water level W2 situation, control part 14 interrupts draining, make washing machine (step S2029) out of service, and make display part 22 show the 3rd error message (step S2030).Above-mentioned the 7th error message is used for informing that draining pump 10 fails normal operation.

More than explanation is, as the method that is used for output the 5th error message, the 6th error message or the 7th error message, the error message that in step S2018, step S2028 and each step of step S2030, shows separately by display part 22, this is the demonstration of sense of vision normally, but different is also can export by sound equipment output units such as buzzer (buzzer), loudspeakers (speaker).

Figure 21 is the precedence diagram of control method of the washing machine of the expression 16th embodiment of the present invention.

The power supplier 19 that below will illustrate is used for applying or cutting off the power supply (with reference to Fig. 2) of supplying with to washing machine 100.

With reference to Figure 21, when the user puts into washings, and when connecting the power supply of washing machine 100,100 apply electric power from power supplier 19 to washing machine.

The user can be by the required control instructions such as washing procedure, wash time, rinsing number of times, dehydration intensity and book setting of input part 15 inputs.And the user also can make washing machine 100 decide suitable washing methods by the amount that detects washings.

As mentioned above, washing methods one determines that washing machine 100 is just carried out the washing stroke of the spot of removing washings, the rinsing stroke of rinsing washings and the dehydration stroke (step S2101, step S2102, step S2103) that dries washings successively.

After above-mentioned dehydration stroke finished, washing machine 100 stopped all operations and is in holding state, stayed the time that the water of the wall etc. of above-mentioned water jacket 2 or inside groove 3 stays with wait.

Aforesaid standby process can be only implemented the user inputs the situation of instruction separately by input part 15 under, also can be set in the situation that the user not have to input and carry out always.

In the present embodiment, dispose separately the button that is used for the input standby command at input part 15, if above-mentioned button is in the state of being pressed, washing machine 100 is just carried out above-mentioned standby process always.For example, if by above-mentioned button once, in the process of washing machine 100 work, 14 of control parts are judged as has inputted standby command, and if remove pressing of above-mentioned button, 14 of control parts are judged as does not have standby command.

Therefore, above-mentioned dehydration stroke one finishes, and control part 14 just judges whether to have inputted standby command by input part 15.At this moment, above-mentioned dehydration stroke comprises simple dehydration and formal dehydration, and when formal dehydration finished, control part 14 judged whether to have inputted above-mentioned standby command (step S2104).

Inputted standby command if be judged as, control part 14 just stops the operation (step S2105) of all devices such as feed water valve 6, draining pump 10 and drive division 13.

If leave Yu Shuishi at wall of water jacket 2 or inside groove 3 etc., remaining water might freeze.Therefore, all flow down until stay the water of the wall etc. of water jacket 2 or inside groove 3, stop all operations, and be in holding state.

Above-mentioned standby can be carried out predefined setting-up time, and control part 14 judges whether passed through setting-up time (step S2106) during standby.Above-mentioned setting-up time is that the water of staying water jacket 2 or inside groove 3 walls all flows down the required time, waits by experiment to preset and store.

The water that flows down to downside in above-mentioned setting-up time is concentrated in above-mentioned draining stream 9 or the draining pump 10.

If passed through above-mentioned setting-up time, just drive draining pump 10, remaining water is all discharged (step S2107).

Between drainage period, the water level that level sensor 20 detects in the water jacket 2.After above-mentioned level sensor 20 sensed water level, be transferred to control part 14 as signal.

Control part 14 is by judging relatively whether the water level that is detected by level sensor 20 reaches predefined draining and finish water level (step S2108).

If the water level that is detected by level sensor 20 reaches above-mentioned draining end water level, control part 14 stops draining (step S2109) after setting-up time.At this, owing to after the above-mentioned water level that detects reaches above-mentioned draining end water level, still might have a small amount of water in the draining pump 10, therefore the time of discharging a small amount of water can be set as above-mentioned setting-up time, and above-mentioned setting-up time also can comprise 0.

As mentioned above, if draining stops, the remaining water that just is judged as in the washing machine 100 is all discharged, and controls above-mentioned power supplier 19, cuts off electric power, powered-down.

As mentioned above, after above-mentioned washing, rinsing and dehydration stroke all finish, before powered-down, guarantee to stay the stand-by time that the remaining current in inside groove 3 and the water jacket 2 get off, thereby effectively remove the remaining water in the washing machine 100, prevent the phenomenon that Yu Shui freezes.

With reference to Figure 22, control part 14 according to predefined washing procedure wash, rinsing and the dehydration stroke (step S2201, step S2202, step S2203)

After above-mentioned dehydration stroke finished, washing machine was carried out to be used for untiing equably and is twined or the stroke of untiing washings (step S2204) of agglomerating washings.

Above-mentioned stroke one end of untiing washings, control part 14 just judge whether the user has inputted the standby command (step S2205) that is used for removing remaining water.

Inputted above-mentioned standby command if be judged as, control part 14 just stops the operation (step S2206) of all devices such as feed water valve 6, draining pump 10 and drive division 13.

Control part 14 judges whether to pass through above-mentioned setting-up time (step S2207) during all devices as above are out of service.

If be judged as through above-mentioned setting-up time, control part 14 moves draining pumps 10, and the remaining water that is brought together after downward effluent is got off is all discharged (step S2208).

During the remaining water of discharge, level sensor 20 sensed water level, control part 14 judges whether the water level that detects reaches predefined discharge level (step S2209).

Reach draining end water level if be judged as the water level that detects, stop the operation (step S2210) of draining pump 10.

As mentioned above, if draining stops, control part 14 just is judged as institute in the washing machine 100 water of having a surplus and has discharged, and controls above-mentioned power supplier 19, cuts off electric power, powered-down.

As mentioned above, for the washing machine of the stroke of carrying out successively washing, rinsing, dewater and untie washings, can after the above-mentioned stroke of untiing washings, carry out the standby step that is used for removing remaining water.That is, the most effectively, after the stroke that finishes the washing that is useful on, before being about to close, carries out power supply above-mentioned standby step.

In the aforesaid embodiment of the invention, input in the situation of standby command just although limit as the user, the situation of carrying out the standby process is illustrated, and is not limited to this.Also can be that the user only need input standby command one time, before the user removes again, irrespectively carry out the standby process with the number of run of washing machine always, if the washing machine that under ultra-low temperature surroundings, uses, also can the user need not to input separately, before power supply is about to close, carry out the standby process always.

More than, the power supply of closing washing machine among other embodiment that the 16th embodiment of the present invention to the 17 embodiment that describe with reference to Figure 21 to Figure 22 are applicable to put down in writing in this specification is removed the situation of remaining water before.At this, but wash, in rinsing and the dehydration which finish after all powered-down be natural.

In the washing machine of one embodiment of the invention, when powering to the various electronic units that consist of washing machine, detect from the variation of the output voltage of above-mentioned electronic unit output, judge whether freezing of above-mentioned electronic unit.

When powering to the various electronic units that consist of washing machine, voltage detection department 18(is with reference to Fig. 2) detect from the output voltage of above-mentioned electronic unit output.Below, voltage detection department 17 can be used for detecting the output voltage of feed water valve 6, or for detection of the output voltage of draining valve 8, or for detection of the output voltage of draining pump 10.

In more detail, if voltage detection department 17 for detection of the output voltage of feed water valve 6, is just judged whether freezing of feed water valve 6 according to the variable quantity of the output voltage of feed water valve 6.

If voltage detection department 17 is for detection of the output voltage of draining valve 8, just judge whether freezing of draining valve 8 according to the variable quantity of the output voltage of draining valve 8.

If voltage detection department 17 is for detection of the output voltage of draining pump 10, just judge whether freezing of draining pump 10 according to the variable quantity of the output voltage of draining pump 10.

On the other hand, control part 14 intercoms mutually with feed water valve 6, draining valve 8 and draining pump 10 electrically, therefore, also can detect by the variation of output signal from draining pump 10 to control part 14 that apply from feed water valve 6, draining valve 8 and and whether freeze.

And, with regard to the washing machine of one embodiment of the invention, according to the circuit structure that applies power supply to electronic units such as feed water valve 6, draining valve 8 and draining pumps 10, also can whether freeze by judging from the variable quantity of the output current of above-mentioned electronic unit output.

Therefore, although below the content of explanation is that variable quantity according to the output voltage of feed water valve 6, draining valve 8 and draining pump 10 detects situation about whether freezing, but in the application's the invention, also can detect the variable quantity of the output current of the electronic units such as feed water valve 6, draining valve 8 and draining pump 10, and judge accordingly and whether freeze.

And heater 28 is arranged in the water jacket 2, is used for heated scrub water.Different is that heater 28 also can be arranged at feed water valve 6, draining valve 8 and draining pump 10.And feed water valve 6 or draining valve 8 can use electromagnetic valve.

Shown in Figure 23 be, after open feed water valve 6 supplies water, 10 drainings of operation draining pump, under the state that feed water valve 6 is closed and draining pump 10 is out of service, after washing machine is held on for a long time temperature and has been configured in the sub-zero chamber (chamber) it be freezed, promote the temperature in the chamber, and apply predetermined power supply to feed water valve 6 and draining pump 10 on one side, Yi Bian detect the output voltage (a) of feed water valve 6 and the output voltage (b) of draining pump 10.

Shown in (a) part of Figure 23, the output voltage of feed water valve 6 sharply descends near T1, and this is because the washings that originally remain in the feed water valve 6 melt near T1.That is, feed water valve 6 is thawed near T1.At this, Vvalve represents the output voltage values under the state that feed water valve 6 freezes, and Vvalve_ref represents thaw output voltage values under the state that finishes of feed water valve 6, and △ Vvalve represents that Vvalve and Vvalve_ref's is poor.

Equally, shown in (b) part of Figure 23, the output voltage of draining pump 10 sharply descends near T2, and this is because the washings that remain in the draining pump 10 melt near T2.That is, draining pump 10 is thawed near T1.At this, Vpump represents the output voltage values under the state that draining pump 10 freezes, and Vpump_ref represents thaw output voltage values under the state that finishes of draining pump 10, and △ Vpump represents that Vpump and Vpump_ref's is poor.

At this, why the thawing time T2 of draining pump 10 is longer than the thawing time T1 of feed water valve 6, is feed water valve more than 6 because the amount of the interior remaining washings of draining pump 10 compares.

Can recognize variable quantity (the △ Vvalve of the output voltage when thawing under the state that feed water valve 6 and draining pump 10 freeze by Figure 23, △ Vpump), but the words of reverse thinking are not difficult to predict, in the process that feed water valve 6 and draining pump 10 freeze, can detect equally the variable quantity of the output voltage that is equivalent to each △ Vvalve and △ Vpump.

And although the variation of the output voltage of not shown draining valve 8 among Figure 23, draining valve 8 also shows the similarly output voltage variation of (a) part with Figure 23.

In the application's the invention, when the various electronic units to formation washing machines such as feed water valve 6, draining valve 8 and/or draining pumps 10 apply predetermined power supply, detect the variable quantity of the output voltage of above-mentioned electronic unit, and reduce predetermined value when above detecting above-mentioned output voltage, execution is thawed.
