In step sl, process control unit 112 receives the input of the procedure selection of the operating process of tumbling-box washing machine S (procedure selection).Herein, user opens door 25, puts into selected washings to the inside of roller 3, and close door 25.And And user is selected and is inputted the program of operating process by operation Operation switch 12,13.By to Operation switch 8a, 8b It is operated, to input the program of the selected operating process arrived to process control unit 112.It is defeated that process control unit 112 is based on institute The program of the operating process entered from operation mode database 111 reads corresponding operation mode, enters step S2 later.This Outside, in the following description, to be illustrated the case where having selected washing procedure (cleaning~rinsing~dehydration twice).

In step s 2, the weight (cloth amount) for the washings for being fed into roller 3 is examined in the execution of process control unit 112 The process (cloth amount sensing detection) of survey.Specifically, 112 drive motor M of process control unit rotates roller 3, and clothing weight The weight (cloth amount) of washings before 114 pairs of calculation part water fillings of amount calculates.

In step s3, process control unit 112, which executes, calculates detergent amount, (the detergent amount operating of the process of the duration of runs Time calculates).For example, detergent amount, scavenging period determination section 116 are based on cloth amount, the conductance of water detected in step s 2 Rate (hardness), the temperature of water, and the detergent dosage and operating time to be put into are determined by corresponding table retrieval.Moreover, process Control unit 112 shows determined detergent amount, the duration of runs in display 22.In addition, for water conductivity (hardness), For the temperature of water, the conductivity (hardness) of the water when the storage unit (not shown) of microcomputer 110 is previously stored with previous operating And water temperature, use the value.

Conductance measurement portion 115 makes conductivity sensor 4, temperature sensor T1 movement, measures the water temperature and electricity of tap water Conductance calculates the hardness of water.The hardness of the water temperature and water that determine herein is stored in detergent amount, scavenging period determination section 116, and the decision of the detergent amount, scavenging period for next time.

In step s 6, process control unit 112 executes 2 (detergent supply) processes that supply water.For example, opening water supply electromagnetic valve 21, detergent and water are supplied along outer groove 2 via detergent pallet 26.After reaching scheduled water level, water supply electromagnetic valve 21 is closed. At this point, if water level is the height for not showing the water surface in roller 3, be able to suppress it is dirty dissolved out from clothing, thus it is preferred that.

In the step s 7, process control unit 112 executes detergent dissolution 1 process (detergent dissolution movement).Specifically, 112 control loop of process control unit pump 54, sprays the water sucked from discharge outlet 51 and detergent from the circulation of recessed portion 63 Mouth is (not shown) to be sprayed.Recessed portion 63 is flowed through from the water and detergent of circulation ejiction opening ejection (not shown), later towards draining Mouth 51, to recycle.Water and detergent are stirred as a result, so that detergent is dissolved in water.If by the predetermined time (such as 10 Second), then process control unit 112 stops circulating pump 54.

In step s 8, detergent type determination unit 119 executes detergent type judgement (judgement of detergent type).This Outside, detergent type judgement is illustrated using Figure 12.

In step s 200, the detergent that the measurement of conductance measurement portion 115 generates in detergent dissolution movement (S7) is dense Spend the water temperature t and conductivity EC of higher cleaning solution.In addition, preferably stopping 21 institute of water supply electromagnetic valve when measuring conductivity EC The rotation for the roller 3 that the circulation and motor M that the water supply to outer groove 2 of progress, circulating pump 54 are carried out are carried out.

In step s 201, whether detergent type determination unit 119 determines the conductivity EC measured in step s 200 It is smaller than first threshold conductivity EC1.In addition, based on the water before the detergent investment detected in step S5 (referring to Fig.1 1) Temperature and conductivity (hardness) set first threshold conductivity EC1.It is smaller than first threshold conductivity EC1 in conductivity EC In the case of (S201: yes), the processing of detergent type determination unit 119 enters step S203.On the other hand, it is not in conductivity EC In the case where smaller than first threshold conductivity EC1 (S201: no), the processing of detergent type determination unit 119 enters step S202.

In step S202, whether detergent type determination unit 119 determines the conductivity EC measured in step s 200 It is smaller than second threshold conductivity EC2.In addition, based on the water before the detergent investment detected in step S5 (referring to Fig.1 1) Temperature and conductivity (hardness) set second threshold conductivity EC2.It is smaller than second threshold conductivity EC2 in conductivity EC In the case of (S202: yes), the processing of detergent state determination unit 119 enters step S204.On the other hand, it is not in conductivity EC In the case where smaller than second threshold conductivity EC2 (S202: no), the processing of detergent type determination unit 119 enters step S205.

In step S203, detergent type determination unit 119 determines liquid detergent (concentration), and cuts in contrast Change the characteristic of conductivity sensor 4.The processing of detergent type determination unit 119 enters step S207.

In step S204, detergent type determination unit 119 determines liquid detergent, and switches conductance in contrast The characteristic of rate sensor 4.The processing of detergent type determination unit 119 enters step S208.

In step S205, detergent type determination unit 119 determines powder detergent, and switches conductance in contrast The characteristic of rate sensor 4.The processing of detergent type determination unit 119 enters step S209.

In step S203~S205, the detergent type determined with detergent type determination unit 119 is comparatively cut Change the characteristic of conductivity sensor 4.For example, by will be as the electricity of the component parts of the oscillating circuit 80 of conductivity sensor 4 Container is switched to be connected from the capacitor of different electrostatic capacitances, change the frequency of oscillating circuit 80.Therefore, conductivity passes The range for the conductivity that sensor 80 can be read also changes.Since powder detergent is in the higher trend of conductivity, so logical The electrostatic capacitance for increasing capacitor is crossed, higher frequency can be become in the lower region of resistance, so that detection becomes easy. Since liquid detergent (concentration) is in the lower trend of conductivity, so by the electrostatic capacitance for reducing capacitor, Neng Gou Become higher frequency in the higher region of resistance, so that detection becomes easy.Since the conductivity of liquid detergent is in powder The intermediate trend of last detergent, liquid detergent (concentration), so by the way that the electrostatic capacitance of capacitor is set as above-mentioned capacity Centre can be such that detection becomes easy.Thus, for example, if conductivity sensor 4 keeps the conductance for detecting powder detergent The characteristic of rate is constant, then has the case where dirty detection becomes difficult when using the detergent of the different other types of conductivity. By switching the characteristic of conductivity sensor 4, optimal measurement result can be accordingly obtained with detergent type, and be not required to Multiple conductivity sensors 4 are set.

In step S206, whether detergent type determination unit 119 determines the water temperature t measured in step s 200 than pre- Fixed threshold temperature t_cGreatly.In water temperature t than threshold temperature t_cIn the case where big (S206: yes), detergent type determination unit 119 Processing enters step S209.On the other hand, in water temperature t not than threshold temperature t_cIn the case where big (S206: no), detergent kind The processing of class determination unit 119 enters step S210.

In step S207~S210, detergent type determination unit 119 determines additional detergent dissolution time.

In step S207~S208, without additional detergent dissolution movement, (nothing chases after detergent type determination unit 119 The movement of solubilization solution) with regard to detergent 2 processes of dissolution of end step S9, the dirty determinating reference value measurement of S10 is entered step later Process (referring to Fig.1 1).

In step S209, detergent type determination unit 119 carries out additional washing with predetermined time T1 (such as 15 seconds) Agent dissolution movement (additional dissolution movement (T1)), the detergent of end step S9 dissolves 2 processes later, and enters step S10's Dirty determinating reference value mensuration operation (referring to Fig.1 1).

In step S210, detergent type determination unit 119 carries out additional washing with predetermined time T2 (such as 45 seconds) Agent dissolution movement (additional dissolution movement (T2)), the detergent of end step S9 dissolves 2 processes later, and enters step S10's Dirty determinating reference value mensuration operation (referring to Fig.1 1).In addition, predetermined time T2 is set as the time than predetermined time T1 long.

In step s 9, process control unit 112 executes detergent 2 processes of dissolution.Specifically, process control unit 112 is controlled Circulating pump 54 processed sprays the water sucked from discharge outlet 51 and detergent from the circulation ejiction opening of recessed portion 63 is (not shown). Water and detergent after recycling ejiction opening ejection (not shown) flow through recessed portion 63, later towards discharge outlet 51, to recycle. Water and detergent are stirred as a result, so that detergent is dissolved in water.If by the addition that is determined in step S207~S210 Dissolution time, then process control unit 112 stops circulating pump 54, terminates detergent and dissolves 2 processes, and enters step 10.

In step slo, dirty concentration determination unit 120 is determined according in step S203, step S204, step S205 Detergent type calculate a reference value (dirty determinating reference value measurement) determined for dirty concentration.In this computation, base Fall into a trap the conductivity measured in the step S200 before dirty dissolution, and according to it is calculated by clothes weight calculation part 114 The corresponding worksheet of clothes weight determines water supply, to solve the dilute strength of detergent liquid.As a result, with dirty concentration On the basis of the conductivity of unpolluted cleaning solution required for determining, the precision of dirty concentration determination unit 120 can be improved.

Rinsing operating is also possible to the liquid detergent of primary concentration type and rinses operating be liquid scrubbing twice Agent is compared, and conductivity becomes smaller, to can also change rinsing times according to the judgement result of dirty concentration determination unit 120.

In step s 11, process control unit 112 executes rotation water process.Specifically, water supply electromagnetic valve 21 is opened, Increase the water level of the cleaning solution in outer groove 2, and control motor M make roller 3 with scheduled rotation speed (such as 40rpm) to Both forward and reverse directions rotation, to carry out the displacement of clothing.Also, by circulating pump 54 control for scheduled rotation speed (such as 2600rpm), by making the spray from the higher cleaning solution of detergent concentration that discharge outlet 51 sucks from the opening portion for being set to outer groove 2 Mouth (not shown) is sprayed to the inside of roller 3, be impregnated with cleaning solution to the clothing inside roller 3.

Moreover, stopped water supply if the water level of the cleaning solution in outer groove 2 rises up to scheduled water level (such as close Water supply electromagnetic valve 21).If terminating to rotate water process, and enter step by the predetermined time after starting rotation water process S12。

In step s 12, process control unit 112 executes prerinse process.Specifically, process control unit 112 will recycle 54 control of pump is scheduled rotation speed (such as 3200rpm, circular flow 48L/min), makes to wash from what discharge outlet 51 had sucked It washs liquid and is sprayed from the nozzle (not shown) for the opening portion for being set to outer groove 2 to the inside of roller 3.Also, make to roll by controlling motor M Cylinder 3 is rotated with scheduled rotation speed (such as 40rpm) to both forward and reverse directions, is washed clap to the clothing inside roller 3.If through Scheduled time (such as 3 minutes) are crossed, then process control unit 112 terminates prerinse process, and enters step S13.

In step s 13, process control unit 112 executes supply water process.Specifically, opening water supply electromagnetic valve 21 It supplies water to outer groove 2.If supplying water until scheduled water level, closes water supply electromagnetic valve 21 and stop water supply, end feeds waterman Sequence, and enter step S14.

In step S14, process control unit 112 executes formal cleaning process 1.Formal cleaning process is that following process (is clapped Wash): the clothing for the lower section being stored in roller 3 is lifted using the rotation of roller 3, and because gravity is higher than for clothing Centrifugal force, and fall clothing from the top in roller 3, mechanical power thus is applied to clothing.

Specifically, process control unit 112 controls circulating pump 54 for scheduled rotation speed (such as 3200rpm, circulation Flow 48L/min), make from the cleaning solution that discharge outlet 51 has sucked from the nozzle (not shown) for the opening portion for being set to outer groove 2 to rolling The inside of cylinder 3 sprays.Also, process control unit 112 control motor M make roller 3 with scheduled rotation speed (such as 40rpm) to Thus both forward and reverse directions rotation clap to the clothing inside roller 3 and be washed.If by scheduled time (such as 5 minutes), process Control unit 112 terminates formal cleaning process 1, and enters step S15.

In step S15, dirty concentration determination unit 120 determines the dirty concentration (dirty concentration judgement) of clothing.It is specific and Speech, conductance measurement portion 115 measures the conductivity of cleaning solution using conductivity sensor 4.In addition, in measurement conductivity EC When, preferably the circulation that is carried out of the water supply to outer groove 2 that is carried out of stopping water supply electromagnetic valve 21, circulating pump 54, motor M are carried out Roller 3 rotation.

Cleaning solution in step S15 is to dissolve out to have dirty solution in cleaning solution by step S12, S14.Namely It says, the variable quantity of calculated a reference value and the conductivity of the cleaning solution measured in step 15 is (dirty to sentence in step slo Definite value) it is to generate the value changed according to dirty, it is able to detect the degree of fouling of clothing.Further, since dirty variable quantity has To the case where positive variation or to the case where negative variation due to the dirty ingredient contained by clothing, so can also be come with absolute value Judge dirty variable quantity.

For dirty decision content, in the uniform situation of degree of fouling of clothing, the amount of clothing the more, dirty to sentence Definite value is bigger.Dirty concentration determination unit 120 is according to dirty decision content and by the calculated clothing weight of clothes weight calculation part 114 Amount, and dirty concentration is calculated from the relational expression found out in an experiment.After calculating dirty concentration, 112 knot of process control unit The dirty concentration judgment process of beam, and enter step 16.

In step 16, cleaning action resets the execution cleaning action of portion 123 and resets process (cleaning action is reset). Cleaning action resets using the variable quantity of cleaning strength the dirty amount (dirty concentration) that determines, water quality (water temperature, hardness), detergent The disturbance degree that the information that type etc. determines in operation generates washing-off properties, and determined clearly according to the variable quantity of cleaning strength Wash time, roller rotational time.The cleaning strength of embodiments of the present invention uses clean ratio.That is, clean ratio is for trying washing machine Wash degree and the ratio between the wash degree of standard washer, in " the performance measurement side of home-use electric washer, Japanese Industrial Standards Regulation in method (JISC9811) ".That is, clean ratio is higher, then washing-off properties are higher.In the present embodiment, as clean The index of power uses clean ratio, and but not limited to this.For example, it is also possible to have the sensor etc. of the form and aspect of measurement clothing, and Use the form and aspect variable quantity etc. in cleaning operating.

For for the disturbance degree of cleaning strength, calculating the variable quantity of clean ratio, and final basis according to two information All information solves the variable quantity of clean ratio.For example, water temperature, hardness, which will influence calculation part 121, to be measured in step s 5 Water temperature and hardness substitute into the relational expression (relational expression of water quality and clean ratio) that finds out in an experiment to solve clean ratio.Also, It is obtained so that the dirty condition (such as 25 DEG C of water temperature, hardness 30ppm) sufficiently fallen is substituted into the relational expression of water quality and clean ratio Clean ratio on the basis of, relative value become influenced by water temperature, hardness after clean ratio variable quantity.

Detergent, dirty influence calculation part 122 calculated dirty concentration will bring into and find out in an experiment in step 15 Relational expression (relational expression of dirty concentration and clean ratio) solve clean ratio.Herein, the relational expression of dirty concentration and clean ratio It is different according to detergent type.Detergent, dirty influence calculation part 122 are according to the detergent type determined in step s 8 To select the relational expression of dirty concentration and clean ratio.Also, with by dirty condition (such as 1 times of the dirty concentration) generation sufficiently fallen On the basis of entering clean ratio obtained from the relational expression of dirty concentration and clean ratio, relative value becomes by detergent type, dirty The variable quantity of clean ratio after the influence of dirty concentration.

The variable quantity of clean ratio based on all information, which becomes, influences calculation part 121 and detergent, dirty by water temperature, hardness Dirt influences total (variable quantity of cleaning strength) of the variable quantity for the clean ratio that calculation part 122 is found out.

Cleaning action resets portion 123 and the variable quantity of cleaning strength is substituted into the relational expression (scavenging period found out in an experiment With the relational expression of clean ratio), to determine additional scavenging period (Tw).It is more than pre- in the scavenging period (Tw) of calculated addition In the case where fixed setting time, additional scavenging period (Tw) is replaced as scheduled setting time.Thereby, it is possible to inhibit because The nigrescence of clothing caused by prolonged cleaning solution dipping.In order to fill up be shortened with additional scavenging period (Tw) it is corresponding Cleaning strength extends roller rotational time and improves running rate.By improving cleaning strength based on the mechanical force increase washed is clapped.
