Description

Washing machine {WASHING MACHINE}

The fully automatic washing machine detects the amount of laundry clothes put in the washing and dewatering tank, injects detergent corresponding to the amount of laundry (laundry clothes), and tap water (washing water) according to the amount of laundry clothes in the washing process. After the water is supplied, the stirring blade is rotated forward and backward, or the washing and dehydrating tank is rotated in one direction, or the forward and reverse rotation is performed a washing process for exerting a mechanical force on the laundry clothes, and then the tap water (rinse water) A rinsing step of exerting a mechanical force on the clothes is performed, and then, the spinning and dewatering tank is rotated thereafter to perform a dehydration step of centrifugal dehydration of the rinsing water contained in the laundry clothes. In the laundry dryer which performs drying of laundry clothes, it is the structure which performs the warm air drying process which blows in and blows warm air after that further.

In such a fully automatic washing machine or laundry dryer, the amount of the synthetic detergent dissolved in the wash water in the washing step is generally about 20 g / 30 L (the amount of the detergent / washing water), and the detergent concentration of the wash water is about 0.07%.

In the case of washing with washing water having such a detergent concentration, the chemical cleaning power of the detergent is not so large. Therefore, in order to remove the dirt attached to the laundry clothes, the rotational force of the stirring blade of the washing machine or the washing and dehydrating tank is increased, or the washing time is extended. In doing so, the mechanical forces acting on the laundry garment must be strengthened. As a result, the present condition is that there is a drawback that the damage of laundry clothes due to mechanical force is increased or the laundry clothes are entangled more.

And when the entanglement of laundry clothes increases, washing nonuniformity will increase and it will become difficult to take out laundry clothes. In addition, in the laundry dryer, the warm air drying in the washing and dewatering tank becomes difficult due to the occurrence of dry unevenness, or the laundry clothes become wrinkled. In order to perform the warm air drying, it is necessary to reduce the mechanical force acting on the laundry clothes and to reduce the entanglement of the laundry. As a result, there are disadvantages in which decontamination is worsened.

In order to reduce the mechanical force acting on the laundry clothes in the washing process, for example, Japanese Patent Application Laid-Open No. 7-80182 discloses adding a preliminary step of immersing the laundry clothes in a high concentration detergent solution before the washing process. A fully automatic washing machine using chemical cleaning power is disclosed.

The present invention relates to a washing machine and a laundry dryer.

The washing machine or laundry dryer is preferably configured to accommodate means for carrying out washing, dehydration and drying in a limited form of housing (width, depth, extension). In particular, in order to effectively exert the chemical cleaning power of the detergent, a means for generating a high concentration of detergent liquid and penetrating the laundry is a new means added to a conventional washing machine or laundry dryer, and these means are reasonably incorporated into the housing. It is necessary to devise to realize a practical washing machine or laundry dryer by installing. Japanese Unexamined Patent Application Publication No. 7-80182 exemplifies dissolving a detergent with twice the weight of laundry weight to produce a high concentration detergent liquid. However, for example, when washing 4 kg laundry, 8L high detergent liquid is used. In order to provide a means for generating and accumulating such a large amount of high concentration detergent liquid, a large housing is required.

It is an object of one of the present invention to propose a practical washing machine which can significantly reduce the mechanical force acting on laundry (laundry clothes) in a washing process by effectively exerting the chemical cleaning power of the detergent using a detergent. .

Another object of the present invention is to provide a washing machine for drying a laundry dehydrated in a washing-and-dehydrating tank by blowing warm air into the washing-and-dewatering tank, which reduces deterioration of contamination by reducing the mechanical force acting on the laundry in the washing step. In order to reduce the entanglement of the laundry in a washing | cleaning and dewatering tank without work, it improves drying efficiency and reduces drying nonuniformity.

Still another object of the present invention is to prevent staining of laundry by a high concentration detergent solution that dissolves and dilutes the powder synthetic detergent and spreads the laundry.

In order to achieve the desired one, the present invention is to dissolve the detergent in a small amount of detergent dissolved water to produce a higher concentration detergent solution than the detergent concentration of the wash water, and by diluting the high concentration detergent solution by spraying the laundry while diluting By using the chemical cleaning power of the detergent which acts on the contamination adhered to the laundry, the cleaning efficiency is increased, and the mechanical force acting on the laundry in subsequent washing is reduced.

In addition, the concentration of the detergent solution sprayed on the laundry to penetrate is a function of the softening agent contained in the detergent that the amount of the effective surfactant is reduced by the hardness component contained in the tap water by dissolving and diluting the powder synthetic detergent with tap water It controls so that it can suppress effectively by.

In the present invention, the detergent is dissolved in a small amount of detergent dissolved water to produce a high concentration detergent liquid (for example, 80 to 500 times the detergent concentration of the wash water), and the high concentration detergent liquid is diluted (for example, a detergent for washing water). By spraying and infiltrating the laundry with 5-20 times the concentration, the chemical cleaning power of the detergent can be effectively exerted, and the mechanical force acting on the laundry in the washing step can be effectively reduced.

Moreover, in the washing machine which dry | cleans the laundry dehydrated in the washing | cleaning and dewatering tank by blowing warm air into the said washing | cleaning and dewatering tank, dry unevenness can be reduced by reducing the entanglement of the laundry.

In addition, the present invention is to dissolve the amount of detergent set in accordance with the amount of laundry to be dissolved in a small amount of detergent dissolved water to produce a high concentration detergent solution, and dilute it so as to penetrate into the laundry while diluting, the amount of detergent suitable for washing efficiently The small detergent dissolution vessel can be used to produce high concentration detergent liquid and wash water of desired detergent concentration for penetration.

In addition, the present invention can be uniformly sprayed on the laundry by spraying a high concentration detergent liquid to the laundry while rotating the stirring blade relative to the washing and dehydration tank by rotating the stirring blade.

By dissolving powdered synthetic detergent with a small amount of detergent dissolved water, a high concentration detergent liquid is produced, and the high concentration detergent liquid penetrates into the laundry. Thus, the chemical cleaning power of the high concentration detergent liquid acts on the contamination adhered to the laundry, resulting in a cleaning action. Therefore, the mechanical force exerted on the laundry in subsequent washing can be reduced. The chemical cleaning action is influenced by the concentration of high concentration detergent liquid that penetrates the laundry.

Since the amount of powdered synthetic detergent used for washing is adjusted according to the amount of laundry, it is preferable to adjust the water supply amount according to this amount of detergent in order to produce a suitable high concentration detergent liquid that generates a desired chemical cleaning power. Specifically, the preferred detergent concentration of the high concentration detergent liquid to penetrate the laundry is 5 to 20 times the standard detergent concentration of the wash water, the preferred detergent concentration is about 10 times. For example, a high concentration detergent solution with a detergent concentration of 10 times is equivalent to a detergent liquid obtained by dissolving a powdered synthetic detergent with 6 L of water in a general washing machine and a laundry dryer, and using 60 L of washing water. It is not preferable to use a detergent dissolution container of a size volume from the viewpoint of the installation place of the detergent dissolution container, so that the high concentration detergent liquid produced by dissolving the powder synthetic detergent with tap water is required to be small amount, For example, it is produced at a concentration higher than that of the high concentration detergent liquid which penetrates the laundry by 200 to 300 mL of tap water, for example, the detergent concentration of the washing water is 200 to 300 times, and dilutes it to the desired detergent concentration. It is configured to be permeated by splashing.

In addition, with a powdered synthetic detergent containing a fluorescent brightener, discoloration (stain) occurs when washing the laundry of the product produced or light color natural. When the fluorescent brightener is attached to the pale yellow laundry and blue-blue light (center wavelength 440 nm) is applied to the reflected light, it appears to be faded and faded. The stain is noticeable if there is a non-uniform penetration of the high detergent concentration into the laundry. Therefore, before spraying the high concentration detergent liquid, it is preferable to apply a small amount of water to the laundry in advance, and then to infiltrate uniformly by spraying the high concentration detergent liquid while rotating the laundry at low speed.

The present invention relates to a washing machine and a laundry dryer which effectively utilize the chemical cleaning power of a high concentration detergent liquid, but since the washing machine can be implemented in a form in which the drying mechanism of the laundry dryer is omitted, the embodiment of the laundry dryer will be described below.

The laundry dryer according to the present embodiment detects the amount of laundry, determines the amount of washing water (washing level), determines the amount of the powdered synthetic detergent required, and dissolves the powdered synthetic detergent with water to form a high concentration detergent. High concentration detergent liquid generation process to generate liquid, preliminary water supply process to include water in the laundry to wet, infiltration process to spray and penetrate wet laundry while diluting high concentration detergent liquid produced by dissolving powder synthetic detergent, and high concentration A fermentation step (omitted as necessary) for washing the laundry infiltrated with the detergent liquid, a washing step, a rinsing step, a dehydration step, and a warm air drying step are performed.

The input switch group 14a of the operation panel 14 is connected to the detergent sensor 40 and the operation panel 14 which detect that the detergent has been put into the detergent dissolution container 21 and executes a control processing program that is already assembled. ), By introducing signals from the water level sensor 15, the rotation sensor 61b and the position sensor 62c, and controlling the driving circuit 16c, the amount of laundry detected, the generation of high concentration detergent liquid, preliminary water supply, high concentration detergent liquid Each process of infiltration, fermentation, washing, rinsing, dehydration and warm air drying is performed, and the progress thereof is displayed by controlling the display element group 14b of the operation panel 14.

The input switch group 14a of the operation panel 14 sets a switch for setting a washing course (standard, strong, soft, dry, handmade, futon, etc.) and a drying course (standard, shirt, finishing, dry, etc.). Switches for setting washing conditions such as washing time, dehydration time, water quantity, rinsing frequency, and switches for setting a drying course (standard, shirt, blanket, etc.) in the case of continuous washing from drying. .

Next, for each of the above steps, a case where washing, dehydration and drying are performed by effectively generating the chemical cleaning power of the detergent by infiltrating the laundry detergent with a high concentration is carried out.

Next, operation | movement of each process of the laundry dryer comprised in this way is demonstrated. 4 is a flowchart of each of the above processes in which the microcomputer 16a in the control unit 16 is executed.

The microcomputer 16a performs the following control process when the washing start button switch of the input switch group 14a is input.

<Step 401>

When the user inserts the laundry clothes 38 into the washing and dewatering tank 2, operates the input switch group 14a of the operation panel 14 to perform initial setting, and the washing start button switch is pressed, the microcomputer 16a is pressed. ) Starts the automatic operation control process of each process.

In the initial setting, a washing course adapted to the laundry, and a washing time, a dehydration time, a quantity, a rinsing frequency, and the like are set as necessary. In addition, when carrying out to drying after washing, a washing drying course is set.

<Step 402>

The detection control process of the laundry amount of the laundry 38 is performed. This laundry amount detection controls the electric drive clutch mechanism 62 of the drive device 6 to the stirring mode in the state of the dry laundry before water supply, energizes the drive electric motor 61 for a short time, and turns the stirring blade 4 on. It drives by rotation and detects it based on the acceleration characteristic at the time of rotation speed increase, or the deceleration characteristic in the inertia rotation at the time of stop of electricity supply to the drive electric motor 61. FIG. Based on this detection result (the amount of laundry to be washed), the amount of washing water and the amount of detergent for generating the washing water having a desired detergent concentration are calculated and determined, and the amount of detergent is displayed by the display element group 14b. The user inputs the powder synthetic detergent into the detergent dissolution container 21 with reference to the displayed detergent amount.

<Step 403>

High concentration detergent liquid is produced. When it is detected by the detergent sensor 40 that the powdered synthetic detergent is put into the detergent dissolution container 21, the auxiliary water supply solenoid valve 22 is opened to provide a small amount of tap water such that water does not overflow into the detergent dissolution container 21. Detergent dissolved water). Then, the detergent stirring electric motor 39 is energized, the stirring blade is driven to rotate, and a high concentration detergent liquid is generated by dissolving the powder synthetic detergent in the detergent dissolving vessel 21 while stirring.

The amount of the detergent dissolved water is uniformly and efficiently dissolved while stirring the powder synthetic detergent of the amount (size) of the detergent dissolving vessel 21 and the amount used for washing with a stirring blade, and furthermore, the water due to foaming of the detergent during stirring The quantity does not cause overflow. For example, when the capacity of the detergent dissolving vessel 21 is 500 mL (volume up to one part 400 mL), the amount of the detergent dissolving water is set to 150 to 200 mL. Detergent dissolved water is controlled by the open valve time of the auxiliary feed water solenoid valve 22. The concentration of the generated high concentration detergent liquid differs depending on the amount of detergent (washing amount, washing amount) injected into the detergent dissolving container 21. For example, the washing water amount of a laundry dryer having a washing capacity of 8 kg is about 24 to 68 L, and the high concentration detergent liquid is 80 to 500 times the detergent concentration of the washing water.

Dissolution time is required for 2-3 minutes. This is because the dissolution time varies depending on the type of powder synthetic detergent, but even a detergent which is difficult to dissolve may have a dissolution rate of 95 to 100% in 2 to 3 minutes, thereby dissolving most detergents.

<Step 404>

Main drive water is supplied by controlling the electric operation clutch mechanism 62 of the drive device 6 in the dehydration and drying mode, and driving the drive motor 61 at low speed to rotate the washing and dehydration tank 2 and the stirring blade 4 at low speed. The solenoid valve 20 is opened to supply tap water directly to the water inlet 19, and preliminary water supply for spraying the tap water onto the laundry 38 in the washing and dewatering tank 2 is performed. The preliminary water supply amount is at least an amount from which the uppermost part of the laundry is leaked to a part of the laundry purchase degree.

Fluorescent brighteners included in powdered synthetic detergents that cause formation or medical stains made of light natural materials are a type of dye and adsorb immediately upon contact with laundry. For this reason, the fluorescent brightener is most likely to adsorb on the uppermost part of the laundry to which the high concentration detergent liquid is directly applied. Therefore, when the high concentration detergent solution is sprayed onto the dry laundry, staining occurs because a difference occurs in the adsorption amount of the fluorescent brightener in a portion where the high concentration detergent liquid flows and a portion where the high concentration detergent liquid has not flowed.

On the other hand, when it falls to some extent from the upper part of laundry, the fluorescent brightener in the high concentration detergent liquid which penetrated almost disappears, and it becomes hard to be influenced by the fluorescent brightener. Since preliminary water supply is performed to wet the laundry, the high concentration detergent liquid is more likely to penetrate. Therefore, the high concentration detergent liquid is uniformly diffused in the laundry, so that the fluorescent whitening agent is uniformly adsorbed on the laundry to prevent staining. However, according to the sensory test for discoloration (staining), the range in which the influence of the fluorescent brightener is allowed by preliminary water supply is 20 times or less (preferably 10 times or less). Level), even if preliminary water supply is carried out, it becomes a level where color change is somewhat concerned. From this point, it is necessary to suppress the concentration of the high concentration detergent liquid to 20 times or less with respect to discoloration (stain).

In addition, the preliminary water supply is preferably controlled in accordance with the amount of the laundry 38 detected by the laundry amount detection step. When the amount of the laundry 38 is small, the preliminary water supply is controlled to increase as the amount of the laundry 38 decreases. This is because when the laundry is wet, the high concentration detergent liquid is more likely to penetrate, so that the high concentration detergent liquid can be uniformly penetrated throughout the laundry. The preliminary water supply amount is controlled by the opening valve time of the main water supply solenoid valve 20. For example, the preliminary water supply amount is about 4 L when the amount of the laundry 38 is less than 4 kg, and about 10 L when the amount of the laundry 38 is 4 to 8 kg.

In addition, this preliminary water supply process is performed simultaneously with the high concentration detergent liquid production process of step 403. This is because two to three minutes are required for dissolving the detergent as described above, and the washing time can be shortened by performing the preliminary water supply step during this time. In addition, since the time from the completion of the preliminary water supply to the end of the detergent dissolution becomes the passing time, the tap water can be sufficiently infiltrated into the laundry 38. For example, when the water supply flow rate from the main water supply solenoid valve 20 sets the preliminary water supply amount to 10 L at 15 L per minute, the preliminary water supply is terminated in 40 seconds. If the detergent dissolution time is 2 minutes, it takes 1 minute 20 seconds.

<Step 405>

The electric operation clutch mechanism 62 of the drive device 6 is controlled in the dehydration and drying mode, and the drive electric motor 61 is operated at low speed to assist the washing and dehydration tank 2 and the stirring blade 4 at low speed. By opening the water supply solenoid valve 22 and diluting and supplying it to the detergent dissolution container 21, the high concentration detergent liquid is diluted and water is supplied from the water supply part to the water inlet 19. At the same time, the main water supply solenoid valve 20 is opened to supply water to the water inlet 19, and the high concentration detergent liquid is diluted with the desired high concentration detergent liquid and sprayed on the laundry 38 in the washing and dewatering tank 2 to wash the laundry 38. Infiltrate). The preferable detergent concentration of the high concentration detergent liquid at this time is mentioned later. Since the laundry 38 in the washing-and-dehydrating tank 2 rotates together with the washing-and-dehydrating tank 2, the high concentration detergent liquid to be poured from the water inlet 19 is uniformly sandwiched in the laundry 38. Penetrate The laundry 38 may be rotated by stirring by rotating the stirring blade 4 in a state where the washing and dewatering tank 2 is stopped. In particular, by rotating the stirring blade 4 relative to the washing and dewatering tank (2), the laundry moves in the washing and dewatering tank (2) and the position is changed, so that a high concentration of detergent liquid is uniformly carried out by the laundry (38). You can splash it.

The high concentration detergent liquid, which is embedded in the laundry 38, quickly penetrates into the laundry 38 and exerts a detergent component on the contamination attached to the laundry 38.

<Step 406>

The laundry 38 penetrated with a high concentration of detergent solution is placed for a predetermined time. This process is a time for further promoting the action of the chemical cleaning power of the detergent against the penetration of the high concentration detergent liquid to the laundry 38 and contamination, and is omitted as necessary.

Here, the improvement of the washing degree by a high concentration detergent liquid is demonstrated.

The powdered synthetic detergent contains, as a detergent component, a surfactant for removing contamination, additives such as builders such as alkali agents, zeolites, enzymes, reattachment inhibitors, and the like, and optical brighteners. Among these components, the surfactants, zeolites, alkali chemicals and enzymes mainly contribute to the cleaning power efficiency when a high concentration detergent liquid is used.

The surfactant collects the lipophilic groups toward the contaminated surface, adsorbs to the contaminants, penetrates the contaminants and laundry by infiltration, dissolves the oil contamination in water by emulsification, and makes it easy to mix lipophilic solid particles with water by dispersing. There is action. Then, by applying a mechanical action of the washing machine, the contamination is separated from the laundry and moves into the washing water.

Fig. 5 is a result of a beaker test showing the relationship between the detergent liquid concentration and the washing ratio penetrating the laundry. This test observes the relationship between the detergent concentration and the cleaning rate when the artificial contaminated laundry was immersed for 5 minutes (without mechanical force) in the detergent liquid produced by dissolving the powdered synthetic detergent with 100 ppm of detergent dissolved water. . Although the washing rate in the detergent concentration (1 time) of the wash water is about 3%, at 5 times the detergent concentration, the washing rate rapidly rises to 12%, and the washing rate is 10 to 15% and 20 to 17%. However, at 10 to 20 times, the increase in the cleaning rate tends to be saturated. From this result, it turns out that the density | concentration of the high concentration detergent liquid is 5 times or more, even about 20 times is the best. In this way, since the action of the surfactant is enhanced in the high concentration detergent solution, the action of removing contamination is greatly improved. Commercially available pre-care detergents are high-density liquid detergents applied directly to contaminated parts such as collars and sleeves before washing, but utilize the effect of FIG. Moreover, the cleaning power of a precare detergent is equivalent to the detergent liquid of 10 times the detergent concentration. By infiltrating the laundry with a high concentration detergent liquid made of a conventional powder synthetic detergent, the effect of the precare detergent can be realized without any troublesome pretreatment.

In addition, when the concentration of the surfactant is increased, the rate of penetration of the detergent liquid into the laundry is improved. 6 is a result of measuring the relationship between the penetration rate of the detergent solution and the detergent solution concentration for the artificial contaminated laundry. Penetration rate is expressed as the ratio to tap water. The rate of penetration is mostly proportional to the detergent concentration. If the detergent concentration is 1 times the same as the wash water, the rate of penetration is almost unchanged with tap water at 1.1, but the detergent concentration is about 3 times at 5 times, about 4 times at 10 times, and about 8 times at 20 times. In this way, when the high concentration detergent liquid is sprayed on the laundry, the permeation rate is high, so the detergent liquid penetrates the laundry at high speed and quickly reaches contamination, and the high concentration detergent component acts strongly on the contamination, thereby improving the washing power. In addition, since the detergent liquid penetrates into the laundry at high speed, the sprayed detergent liquid does not penetrate into the laundry tank bottom (outer tank) without penetrating into the laundry, so that the high concentration detergent liquid can effectively penetrate the laundry.

The zeolite removes (softens) the metal ions (hardening components) contained in the tap water, thereby suppressing the production of metal soap generated by bonding the surfactant and the hardness components. That is, it functions to suppress the reduction of the amount of the effective surfactant in the laundry. It becomes.

However, the high concentration detergent liquid (e.g., 10 times the detergent concentration of the washing water detergent concentration) produced by dissolving the powder synthetic detergent with a small amount of tap water (detergent dissolved water) has a small amount of metal ions, so that zeolite is sufficiently It is possible to suppress the decrease in the effective and effective surfactant in a very small amount (about 2%).

Fig. 7 shows the relationship between the hardness of detergent dissolved water and the amount of effective surfactant (the amount of surfactant that can act on contamination) when the zeolites use powder synthetic detergent. The amount of effective surfactant is shown by the ratio with respect to the amount of surfactant added. That is, 100% indicates that all of the added surfactant is effective, and the smaller the ratio indicates that the hardness component and the surfactant are combined to saponify the metal to decrease the amount of the surfactant.

The higher the hardness, the less effective surfactant amount is. The ratio of the effective surfactant at a hardness of 100 ppm was 9% at a detergent concentration of 1%, and the amount of the active surfactant was reduced by 10%, whereas the amount of the active surfactant was 98% at a high concentration of 5 to 10 times the detergent concentration. The reduction stops at 2%.

As described above, in the high concentration detergent solution, the amount of zeolite is large relative to the amount of detergent dissolved water, so that metal ions are removed (softened) from the detergent dissolved water, thereby ensuring the amount of effective surfactant. Therefore, the above-mentioned action of the surfactant is sufficiently exhibited, and high cleaning power can be obtained. Thus, zeolite is used as a softening agent which softens water (hard water) with high hardness.

Alkaline has the function of saponifying the alkalinity (PH) of the detergent liquid and saponifying the free fatty acid in sebum contamination, and making it easy to remove the contamination. 8 is a characteristic diagram showing the relationship between detergent concentration and alkalinity PH of the detergent solution. The alkalinity rapidly rises from the tap water (PH 7.3) to the detergent concentration (1 times the detergent concentration) of the wash water, and reaches a pH of about 10. Thereafter, as the detergent concentration increases, the temperature rises slowly, and the pH is about 11 at 10 times the concentration of the detergent.

9 is a characteristic diagram of a beaker test showing the relationship between alkalinity (PH) and chemical cleaning rate in wash water having a detergent concentration of 1 times. This test observes the change in the cleaning rate when the alkalinity is changed by adding an alkaline agent to the detergent liquid (washing water) having a detergent concentration of 1 times that is produced by dissolving the powder synthetic detergent with detergent dissolved water of hardness O ppm. . The cleaning rate at an alkalinity of 10 (equivalent to 1 times the detergent concentration is about 6%) is about 6%, but at an alkalinity of 11 (corresponding to a detergent solution of 10 times the detergent concentration), the cleaning rate is about 8%. It can be seen that the cleaning power increases due to the improvement.

Enzymes have the effect of degrading proteins and fats in contamination, and facilitate the removal of contamination by surfactants. Fig. 10 is a characteristic diagram of a beaker test showing the relationship between detergent concentration and detergent power in the detergent liquid with and without enzymes. In this test, the relationship between the concentration and the cleaning rate of the detergent solution produced by dissolving the powdered synthetic detergent with only the presence or absence of enzyme was dissolved in detergent dissolved water with a hardness of O ppm. As the detergent concentration increases in the powder-synthetic detergent containing the enzyme, the cleaning rate is greatly increased, and the high concentration enzyme promotes the decomposition of protein contamination and lipid contamination.

As mentioned above, by spraying and penetrating a high concentration detergent liquid into laundry, it is possible to greatly improve the washing power by the action of a high concentration of a surfactant, a zeolite, an alkaline agent and an enzyme.

<Step 407>

The main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 are opened to start supplying tap water (washing water). Although the water supply of this wash water is performed to the quantity determined in step 402, it stops in order to detect the laundry amount (wet value) of the laundry 38, and the quality of laundry in the middle of water supply. This interruption level is a level suitable for detecting the amount of wet laundry and the quality of the laundry already set in the microcomputer 16a. The auxiliary water supply solenoid valve 22 is opened to clean the detergent dissolving vessel 21. The washing / dehydrating tank 2 and the stirring blade 4 may be rotated at a low speed as in step 405. This is because when the tap water is supplied, the detergent liquid having a concentration of about 10 times that has infiltrated the laundry 38 is gradually diluted, but the detergent in the laundry is supplied by rotating the washing and dehydrating tank 2 to supply water while rotating the laundry 38. This is because the liquid is diluted uniformly and the variation of the decontamination can be reduced. When water is supplied to the stop level, the concentration of the detergent liquid is about twice, and thereafter, it is not necessary to supply water while rotating the washing and dehydrating tank 2.

<Step 408>

The amount of wet laundry and the quality of the laundry are detected to correct the washing water supply amount and determine the washing process (washing process and rinsing process). The quality of the laundry is determined by stopping the water supply at a predetermined low water level, controlling the electrically operated clutch mechanism 62 of the drive device 6 to the stirring mode, pressing the drive motor 61 for a short time, and rotating the stirring blade 4. After driving, it detects the 1st deceleration characteristic (wet-packed laundry amount) in the inertia rotation at the time of turning off, continues to restart water supply, replenishes wash water to predetermined high water level, and stops water supply, and the drive device 6 The driving motor 61 is pressed for a short time to rotate and drive the stirring blade 4 to detect the second deceleration characteristic in the inertia rotation when it is turned off, and based on the difference between the first damping characteristic and the second damping characteristic. The quality of the laundry 38 is detected. The quality detection control of the laundry is omitted when it is unnecessary by the initial setting. Then, time and water flow (strong mechanical agitation) in the washing and rinsing process are determined according to the quality of the laundry.

<Step 409>

Tap water is supplied to the amount (water level) determined in step 402. By this water supply, the wash water dilutes the high concentration detergent liquid and becomes a detergent concentration (1 time) desirable for washing. Thereby, the laundry 38 is in the state which was immersed in the wash water of predetermined detergent concentration (1 time) in the washing | cleaning and dehydration tank 2. As shown in FIG.

In the water supply of steps 407 to 409, the high concentration detergent liquid is diluted with high hardness tap water, but since the detergent component penetrates the laundry at high concentration and acts on the contamination, the cleaning effect of the detergent component is prevented by the water supply. It is not impeded.

<Step 410>

The drive device 6 is controlled to perform the washing process of the washing water flow and washing time set in step 408. In this washing process, the drive device 6 controls the electrically operated clutch mechanism 62 in the washing mode, and repeats the forward and reverse operation of the drive electric motor 61 to wash and dehydrate the tank 2 and the stirring blade 4. Rotate forward and backward by repeating in the opposite direction.

Here, the relationship between the washing time in a washing process, a washing | cleaning degree, and laundry entanglement rate is demonstrated.

11 shows the relationship between washing time and washing degree. In the washing process, the washing and dewatering tank 2 and the stirring blade 4 are repeatedly rotated in the opposite direction to apply the mechanical force to the laundry 38 in order to remove the dirt attached to the laundry 38. In addition, the chemical cleaning power of the detergent acts on the contamination of the laundry 38.

The characteristic curve 1001 is obtained when the washing process is performed by dissolving the detergent in washing water without performing the step of infiltrating the laundry detergent 38 with a high concentration of the detergent liquid. That is, the washing time and the degree of washing when the washing step is performed in the conventional washing method are shown. The conventional washing method is to wash the laundry by putting a detergent at a ratio of 20g / 30L, which is the amount of detergent required for washing.

Washing removes the contamination from the laundry due to the chemical force of the detergent against the washing of the laundry and the effect of increasing the mechanical power of the washing machine. Thus, the washing is improved in accordance with the relationship between the washing time and the cleaning index. The conventional washing time is about 8 to 10 minutes in general, and the cleaning index at this time is 50 times.

The characteristic curve 1002 is obtained when the washing (stirring) process is performed after the high concentration detergent liquid has penetrated the laundry 38. In this embodiment, since the washing process is performed after the high concentration detergent liquid has penetrated the laundry 38, the degree of washing according to the characteristic curve 1002 can be obtained, and thus, a small mechanical force in a relatively short washing time is achieved. The required degree of washing can be obtained by this.

Thus, 90 degree of washing | cleaning can be implement | achieved by making it move to a washing | cleaning process and making it stir for about 8 minutes after infiltrating a high concentration detergent liquid.

From this point of view, even if the washing time is less than 5 minutes, the contamination of the laundry 38 can be removed better than before by employing a washing method in which a high concentration detergent liquid is poured into the laundry 38. For this reason, the high concentration detergent liquid permeation washing | cleaning system which improves washing power even if the mechanical force of a washing machine is reduced can be provided.

Here, the mechanical force can be controlled by adjusting the on-off time limit of the forward and reverse rotation of the washing-and-dehydrating tank 2 and the stirring blade 4, adjusting the rotation speed, or adjusting the washing (stirring) time.

12 shows the relationship between washing time and laundry entanglement rate. The characteristic curve 1101 is when the washing process is performed with a small mechanical force, and the characteristic curve 1102 is when the washing process is performed with a large mechanical force. Since the mechanical force in the washing process is proportional to the magnitude of the stirring force (normal rotation angle or rotational speed) of the washing and dehydrating tank 2 and the stirring blade 4, in order to generate a large mechanical force, the washing and dehydrating tank 2 And the rotation angle of the stirring blade 4 becomes large, and the laundry entanglement rate becomes large. In this embodiment, since the required washing | cleaning power can be acquired by a small mechanical force, a washing process can be performed by the laundry entanglement rate of the characteristic curve 1101, and the laundry entanglement rate of 10% or less can be implement | achieved. In other words, by adopting a high concentration detergent liquid permeation cleaning method, the contamination of the laundry 38 is better removed than the conventional cleaning method even with a small mechanical force, so that the mechanical force of the washing machine can be reduced to reduce damage or entanglement of the laundry 38. Can be.

<Step 411>

<Step 412>

At this time (at the time of water supply for final rinsing when rinsing a plurality of times), the auxiliary water supply solenoid valve 22a is also opened as needed, and a fiber softener is injected.

<Step 413>

The drive device 6 is controlled to carry out a rinsing process. In the washing process by the high concentration detergent liquid permeation washing method, since the softening action by the zeolite in the high concentration detergent liquid works, the amount of generation of metal soap which increases the adsorption of the surfactant to the laundry 38 is suppressed. As a result, the release of the surfactant in the rinse is promoted, the rinsing performance is improved (the dilution degree is reduced by about 20%, the dilution: the ratio of the amount of the surfactant in the rinsing water to the amount of the surfactant in the wash water), A predetermined rinse can be performed with a small rinsing force (mechanical force).

<Step 414>

The drain solenoid valve 33 is opened to drain the rinsing water out of the apparatus.

<Step 415>

The washing and dewatering tank 2 is operated by controlling the electric operation clutch mechanism 62 of the drive device 6 in the dewatering and drying mode with the drain solenoid valve 33 open, and driving the drive motor 61 at high speed. Centrifugal dehydration of the water in the laundry 38 by rotating the stirring blade 4 and the stirring blade 4 integrally at a high speed. In the state where this centrifugal dehydration is complete | finished, the laundry 38 is a state stuck to the side wall of the washing | cleaning and dehydration tank 2, and is attached.

<Step 416>

The electric drive clutch mechanism 62 of the drive device 6 is controlled in the dehydration and drying mode, and the drive motor 61 is operated at low speed to rotate the washing / dehydration tank 2 and the stirring blade 4 at low speed while blowing the blower. In operation 26, air in the outer tank 5 is sucked out of the intake port 5a, and in the process of ascending the inside of the water-cooled dehumidification duct 23, from the cooling water spraying part 24 into the water-cooled dehumidification duct 23. Cooling dehumidification is performed by the cooling water to be supplied, suctioned into the circulation fan 26 through the descending air passage duct 25, and the air outlet 30 is discharged from the circulation fan 26 through the rising air passage duct 27 and the heater 29. And circulating air heated by the heater 29 to blow in the opposite direction to the rotational direction of the washing / dehydrating tank 2 toward the inner wall surface of the washing-and-dehydrating tank 2, The laundry in the dehydration tank 2 is dried.

When the laundry 38 is warm-dried in a state in which it is centrifugally dehydrated and attached to the side wall of the washing-and-dehydrating tank 2, wrinkles are generated in the laundry 38. Thus, during the drying time, the stirring blade 4 is periodically rotated forward and backward. The laundry 38 is moved to dry.

If the laundry entanglement rate is 10% or less, even after hot air drying as mentioned above after the final dehydration is completed, it is possible to prevent the occurrence of dry unevenness and wrinkles.

The dilution water flow rate and the quantity of water are set by the water flow rate (water flow path area) and the water supply time of the main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 which perform these water supply, but the actual water supply flow rate is a water source ( Fluctuates by water pressure). Therefore, the water flow rate of the main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 is set based on the water flow rate at the minimum predictable water pressure, and monitors the water level sensor 15 for a predetermined amount. The actual water supply time at the time of water supply to the water level is measured, and the water pressure of the water source is obtained and stored by calculation processing based on the measured water supply time, and the main water supply solenoid valve (20) at the time of the wet water supply, detergent solution water supply, and dilution water supply. ) And the auxiliary water supply solenoid valve 22 are intermittently opened and closed to intermittently supply water so as to control the flow rate so that the average value becomes a predetermined flow rate.
