S11 when plugged and when washing machine is brought into operation, the water level that detects in the water jackets 2 by level sensor 20, and detected value and the first designated water level compared, judge whether overflow S12 in the water jacket 2.The reason of carrying out said process is whether before the washing machine operation particular case occurs in order to detect, and fills out in the water jacket 2 and rises washings, and its amount exceeds certain level and overflows water jacket 2.For example, at water-supply valve 6 abnormals and under the pent state of the power supply of washing machine, the situation of washings is supplied with in water jacket 2 interior continuation.Therefore, the first designated water level is preferably considered the water level that washings overflow from water jacket 2 and is set.
In step S12, when the water level in being judged as water jacket 2 was higher than the first designated water level, control part 14 was by display part 22 outputs the 3rd error message S13, and the 3rd error message is in order to make the user identify the message of overflowing and exporting.
Subsequently, control part 14 operation draining pumps 10 are discharged the washings S14 in the water jacket 2, and when within the set time, the S15 when being lower than the second designated water level that becomes of the water levels in the water jacket 2 closes (OFF) the 3rd error message S16.The second designated water level preferably is set as, and is in the empty water level of the state that the washings in the water jacket 2 all are discharged from.Below, the situation take the second designated water level as the sky water level is described as example.
Simultaneously, in step S15, when the water level in the water jacket 2 does not reach the second designated water level, make draining pump 10 continue operation, when water discharge time reaches the first draining setting-up time, and the S17 when not reaching the second designated water level of the water levels in the water jacket 2, control part 14 will compare S18 by temperature sensor 18 detected temperature and the first fiducial temperature, its result, when being judged as above-mentioned detected temperature and being lower than the first fiducial temperature, show the first error message S19 by display part 22, when being judged as above-mentioned detected temperature and being higher than the first fiducial temperature, by display part 22 outputs the second or the 3rd error message S20.
Below, with reference to Figure 12 b, carry out specific description to whether freezing deterministic process for the second time.
For the second time whether freeze deterministic process, the water level in water jacket 2 is lower than under the condition of the first designated water level and carries out.Namely, in step S12, be judged as the situation that is lower than the first designated water level by level sensor 20 detected water levels, or at process step S12, S13, S14, S15, S16, water level in the water jacket 2 becomes and is lower than in the situation of the second designated water level, and the process that is used for carrying out is afterwards judged and whether freezed.
For the second time whether freeze deterministic process and comprise, the step S21 that will compare by temperature sensor 18 detected temperature and the second fiducial temperature.In step S21, when above-mentioned detected temperature is the second fiducial temperature when following, control part 14 controls are by display part 22 outputs the first error message S22.
Water levels in the water jacket 2 among the step S21 can be the first designated water level following (when S12 directly enter into S21 later on possible situation), or the second designated water level following (can enumerate carry out successively S13, S14, S15, S16 after, the situation that the water level of water jacket 2 reaches the sky water level is example).When the water level of water jacket 2 is higher than the second designated water level, and when being lower than the first designated water level, temperature sensor 18 will detect the temperature of the washings in the water jacket 2.In addition, when the water level of water jacket 2 is lower than the second designated water level (for example, empty water level), temperature sensor 18 will detect the temperature of the air of washing machine internal.The second fiducial temperature preferably considers the freezing point of washings and is set as subzero value, considers the situation that detects the temperature of air by temperature sensor 18, its can be set to subzero several times below.
In step S21, when being judged as when being lower than the second fiducial temperature by temperature sensor 18 detected temperature, when the temperature that control part 14 is judged as washing machine internal is low to moderate the degree that can freeze fully, immediately by display part 22 outputs the first error message S22.Detect by whether freezing of carrying out of S21 and S22, irrelevant with the draining characteristics of washings, and just according to judging based on the detected value of temperature sensor 18 or whether prediction is freezed.But, be not to be defined in the order that illustrates among Figure 12 b, but can carry out by any time point in the washing machine running.
Particularly, the second fiducial temperature preferably is set to suitable value by experiment, make in step S21, when being that the second fiducial temperature is when following by temperature sensor 18 detected temperature, can dope with the sufficient degree of accuracy structure member of washing machine, can be frozen such as water-supply valve 6 or draining pump 10 etc.
Simultaneously, in step S21, when being higher than the second fiducial temperature by temperature sensor 18 detected temperature, control part 14 will compare S23 by level sensor 20 detected water levels and the 3rd designated water level.
Above-mentioned detected water level is higher than the situation of the 3rd designated water level, the washings that expression water jacket 2 interior existence the 3rd designated water levels are above and the first designated water level is following.In the case, control part 14 operation draining pumps 10 are carried out draining S25.Carrying out draining with the second draining setting-up time, when the fluctuation of water table value water jacket 2 in is a reference value S26 when above, be judged as normally and carry out in the draining, and detection washing bag amount S24.In step S26, when the fluctuation of water table value in through the situation of the second draining setting-up time S27 or a reference value when following, to compare S28 by temperature sensor 18 detected temperature and the 3rd fiducial temperature, when control part 14 is lower than the 3rd fiducial temperature in above-mentioned detected temperature, control is by display part 22 outputs the first error message S29, when above-mentioned detected temperature was higher than the 3rd fiducial temperature, control was by display part 22 outputs the second error message S30.Whether freezing for the third time deterministic process is to carry out under the condition below the 3rd designated water level with the water level in water jacket 2, and the washing bag amount detecting step S24 that it illustrates in Figure 12 b carries out later on.
