Description

Washing Machines & Laundry Dryers {WASHING AND DRYING MACHINE}

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

The fully automatic washing machine detects the amount of laundry clothes put in the washing and dehydrating tank, injects detergent corresponding to the amount of laundry (laundry clothes), and supplies tap water (washing water) according to the amount of laundry in the washing process. Afterwards, 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 carried out to perform a washing process in which the mechanical force is applied to the laundry clothes, and then the water (rinse water) A rinsing step of exerting a mechanical force on the clothes in the same manner, followed by rotating the washing and dewatering tank 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 further performs the warm air drying process which blows and blows warm air after that.

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 (amount of detergent / wash amount), and the detergent concentration of the wash water is about 0.07%.

In order to perform the washing to remove the dirt attached to the laundry clothes by washing water having a low detergent concentration, the mechanical force acting on the laundry clothes is increased by increasing the rotational force of the stirring blade or the washing / dehydrating tank or increasing the washing time. You must be strong. As a result, the reality is that there is a drawback that damage to laundry clothes due to mechanical force is increased, or that laundry clothes are entangled more.

When the laundry clothes become entangled, washing is not evenly performed, and it becomes difficult to take out the laundry clothes. In addition, in the laundry dryer, since the warm air drying in the washing and dewatering tank becomes difficult due to the occurrence of drying unevenness, in order to perform the warm air drying, it is necessary to reduce the mechanical force acting on the laundry clothes and reduce the laundry entanglement. The result is a drawback of poor contamination.

To reduce the mechanical forces acting on laundry clothes in the laundry process, for example, Japanese Patent Laid-Open No. 7-80182 discloses a high concentration detergent by adding a preliminary step of soaking the laundry clothes in a high concentration detergent solution before the washing process. A fully automatic washing machine utilizing a chemical cleaning power is disclosed. In addition, Japanese Laid-Open Patent Publication No. 8-47594 discloses a washing machine called or washed by washing water having a high detergent concentration.

The washing machine or laundry dryer is preferably configured to accommodate means for carrying out washing, dehydration and drying in a limited form of case (width, depth, height). In particular, in order to effectively exert the chemical cleaning power of the detergent means for generating a high concentration of detergent liquid and immersed in the laundry is a new means added to the conventional washing machine or laundry dryer, these means are reasonably installed in the case Research is needed to realize practical washing machines or laundry dryers. Japanese Laid-Open Patent Publication No. 7-80812 exemplifies dissolving a detergent in water twice the weight of the laundry to produce a high concentration detergent liquid. However, for example, when washing 4 kg laundry, 8L high concentration detergent liquid is used. It is equivalent to, and it is difficult to provide a means for generating and accumulating such a large amount of a high concentration detergent liquid, which is not practical.

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

Another object of the present invention is a laundry dryer for drying a laundry dehydrated in a washing-and-dewatering tank by blowing hot air into the washing-and-dewatering tank, whereby the mechanical force acting on the laundry in the washing step is less likely to be contaminated. In order to reduce the entanglement of the laundry in a washing | cleaning and dewatering tank, it improves a drying efficiency, and reduces a drying nonuniformity.

Still another object of the present invention is to prevent discoloration of laundry by high concentration detergent liquid by dissolving and diluting the powder synthetic detergent into the laundry.

In the present invention, the detergent is dissolved in a small amount of detergent dissolved water to produce a high concentration detergent liquid that is higher than the detergent concentration of the wash water, and the high concentration detergent liquid is diluted and immersed (infiltrated) in the laundry, thereby contaminating the dirt attached to the laundry. The cleaning efficiency is improved by utilizing the chemical cleaning power of the detergent acting on the washing machine, and the mechanical force acting on the laundry during subsequent washing is reduced.

By dissolving a powdered synthetic detergent in a small amount of detergent dissolved water, a high concentration detergent liquid is produced, and the high concentration detergent liquid is immersed (infiltrated) in the laundry, so that the chemical cleaning power of the high concentration detergent liquid acts on the dirt attached to the laundry. Since the action takes place, it is possible to reduce the mechanical force acting on the wash liquid during subsequent washing. The chemical cleaning action is affected by the concentration of the high concentration detergent solution immersed in the laundry.

Since the amount of the powdered synthetic detergent to be used for washing is adjusted according to the amount of laundry, it is preferable to adjust the water supply amount according to the amount of the detergent in order to produce a suitable high concentration detergent liquid that generates the desired chemical cleaning power. Specifically, the preferred detergent concentration of the high concentration detergent liquid immersed in the laundry is 5 to 30 times the standard detergent concentration of the wash water, and 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 synthetic powder 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 desirable to use a volume of detergent dissolving container from the point of view of the installation place of this detergent dissolving container, so that the high concentration detergent liquid produced by dissolving the powder synthetic detergent into tap water is required to dissolve the powdered detergent. For example, it is produced at a concentration higher than that of the high concentration detergent liquid immersed in the laundry by 200 to 300 mL of tap water, for example, 200 to 300 times the concentration of the detergent in washing water, and poured into the laundry while diluting it to the desired detergent concentration. Configure to soak.

In addition, discoloration of the laundry by the high concentration detergent liquid becomes remarkable when there is a non-uniform immersion of the high concentration detergent liquid on the laundry. Therefore, it is preferable that the high concentration detergent liquid is uniformly immersed by pouring the laundry while it is wet with water and rotating at a 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. However, 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 in this embodiment detects the amount of laundry to determine the amount of laundry (washing water level), determines the amount of powder synthetic detergent required, and dissolves the powder synthetic detergent in water to provide a high concentration detergent solution. A process for producing a high concentration detergent liquid to be produced, a process of containing water in the laundry to wet it, an immersion process for dipping and immersing the high concentration detergent liquid produced by dissolving the powdered synthetic detergent into a wet laundry, and dipping the high concentration detergent liquid. A washing process, a washing process, a rinsing process, a dehydration process, and a warm air drying process are performed to keep the laundry as it is.

Next, for each of the above steps, a case where washing, dehydration, and drying is performed by effectively generating the chemical cleaning power of the detergent by immersing the high concentration detergent liquid in the laundry will be described.

4 is a flowchart of each of the above steps executed by the microcomputer 16a in the control unit 16.

The microcomputer 16a executes the following control process when the washing start button switch in the input switch group 14a is put in.

Step 401

When washing clothes 38 are put into the washing and dewatering tank 2, initial setting is performed by operating the input switch group 14a of the operation panel 14, and when the washing start button switch is pressed, automatic operation of each process is performed. Start the control process.

In the initial setting, various kinds of information for avoiding discoloration caused by immersing and washing a high concentration detergent liquid in the laundry 38 are set. Specifically, information such as the quality of the laundry 38, the type (type and color and pattern) of the laundry, the washing method, and the like are set as necessary.

Step 402

Detection control processing of the amount of laundry 38 is performed. This quantity detection controls the electrically operated clutch mechanism 62 of the drive device 6 in the stirring mode or the washing mode in the dry state before water supply, and applies the drive motor 61 for a short time to rotate the stirring blade 4. The drive is performed by detecting the attained rotational speed during driving.

An amount of powdered synthetic detergent is added.

Step 403

The electric operation clutch mechanism 62 of the drive device 6 is controlled in the dehydration / drying mode, and the drive electric motor 61 is operated at low speed to rotate the washing / dehydration tank 2 and the stirring blade 4 at a low speed. The solenoid valve 20 is opened and the tap water is directly supplied to the water inlet 19 so that the tap water is spread on the laundry 38 in the washing and dewatering tank 2. The laundry 38, which absorbs the scattered tap water and wets, is reduced in volume, so that a high concentration of detergent solution is uniformly well penetrated and easily immersed. The amount of scattering of tap water at this time is controlled in accordance with the amount of laundry 38 detected by the detection step. When the amount of laundry 38 is small, it is controlled to be smaller and to increase as it increases. The amount of tap water scattered on the laundry 38 is, for example, about 4 L when the amount of the laundry 38 is less than 4 kg, and 10 L when the amount of the laundry 38 is 4 kg to 8 kg. This amount of water is controlled by the valve opening time of the main water supply solenoid valve 20.

Then, the tap water is placed in the wet state for some time as necessary to sufficiently infiltrate the laundry 38. This holding time is controlled according to the amount of laundry 38 and the amount of tap water scattered. While the washing and dewatering tank 2 may be stopped during the mounting time for sufficiently spreading the tap water into the laundry 38, the washing and dewatering tank 2 may be rotated at a low speed in order to quickly penetrate it.

Step 404

The auxiliary water solenoid valve 22 was opened to supply a small amount of tap water (detergent dissolved water) to the detergent dissolving container 21, and the detergent dissolving container 21 was introduced to generate washing water having a desired detergent concentration. A high concentration detergent liquid is produced by dissolving the powder synthetic detergent in) under stirring with a stirring blade. The amount of detergent dissolved water is uniformly and efficiently dissolved while stirring the volume (size) of the detergent dissolution container 21 and the amount of the powder synthetic detergent used for washing with a stirring blade, and the zeolite contained in the detergent is dissolved in the detergent dissolved water. The amount of water that can substantially prevent the production of the metal soap by the hardness component of, for example, is set to 200 to 300 mL, to produce a highly concentrated detergent solution with a detergent concentration of 200 to 300 times the wash water.

Step 405

By controlling the electric operation clutch mechanism 62 of the drive device 6 in the dehydration and drying mode, the drive motor 61 is operated at low speed to assist the washing and dehydration tank 2 and the stirring blade 4 at a 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 watered from the water supply part to be sent to the water inlet 19 and at the same time the main water supply solenoid valve 20 is opened. (19), the high concentration detergent liquid is diluted with the desired high concentration detergent liquid, poured into the laundry 38 in the washing and dewatering tank 2, and immersed in the laundry 38. 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 with the washing-and-dehydrating tank 2, the high concentration detergent liquid poured from the water inlet 19 is uniformly poured in the laundry 38. Immerse. 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.

The high concentration detergent liquid poured into the laundry 38 rapidly immerses the inside of the laundry 38 to exert a detergent component on the dirt attached to the laundry 38.

Step 406

The laundry 38 in which the high concentration detergent solution is poured is immersed 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.

Powdered detergents contain surfactants that reduce contamination as detergent components, and additives such as builders such as alkali agents, zeolites, enzymes, reattachment inhibitors, and the like that assist the active agents. Zeolite functions to suppress the reduction of the amount of effective surfactant in the wash water by removing (softening) the divalent or higher metal ions (hardening components) contained in the tap water, thereby suppressing the reduction of the amount of the effective surfactant, but the powder synthesis In wash water produced by dissolving a detergent in a large amount of tap water, the amount of zeolite is insufficient and the effective surfactant is greatly reduced.

However, the high concentration detergent liquid produced by dissolving the powdered synthetic detergent in a small amount of tap water (detergent dissolved water) (for example, 10 times the detergent concentration of the washing water detergent concentration) has a small amount of divalent or more metal ions. Zeolite can function sufficiently and the reduction of effective surfactant can be suppressed in a very small amount (about 2%). Therefore, by pouring and immersing such a high concentration of detergent liquid into the laundry, the detergent liquid penetrates into the laundry (contaminated clothing) at a high speed (for example, about four times the speed of the wash water with respect to JISC9606 wet cloth contaminated cloth) and contaminates quickly. The surfactant promotes emulsification and dispersion of the contamination, the alkaline agent promotes swelling and saponification of the oil, and the enzyme effectively exerts a cleaning power to decompose contamination of fat or protein.

FIG. 5 shows the effective amount of surfactant (chemical cleaning power) and the powdered synthetic detergent dissolved in a small amount of detergent dissolved water when the powdered synthetic detergent was dissolved in washing water (detergent concentration 1 times) and the laundry 38 was soaked. It shows the relationship between the amount of effective surfactant (chemical detergency) and the hardness of water used when the produced high concentration detergent liquid (5 times, 10 times detergent concentration) is immersed in laundry.

The amount of effective surfactant (chemical detergency) of the detergent liquid produced by dissolving the powdered synthetic detergent in water is influenced by the amount of the hardness component contained in the water, that is, the hardness of the water, as described above. Therefore, the amount of effective surfactant decreases by 10% when the detergent concentration (1 times) of the wash water is 100 ppm of water, but decreases only 2% when the concentration of the detergent is 5 to 10 times higher. I can keep it.

6 is a characteristic diagram of a beaker test showing the relationship between the detergent liquid concentration immersed in the laundry and the chemical cleaning rate. This test observes the relationship between the detergent concentration and the cleaning rate of the detergent solution 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%, a washing rate of 12% is obtained at a detergent concentration of 5 times, and a cleaning rate of 15% is obtained at a detergent concentration of 10 times. I can see your luggage.

7 is a characteristic diagram showing the relationship between detergent concentration and alkalinity (PH value) of detergent solution. The alkalinity increases with increasing detergent concentration, and the alkalinity at a high detergent concentration of about 10 times becomes about 11, compared with the alkalinity (PH value) of about 10 in the detergent concentration of the wash water, thereby increasing the chemical cleaning power.

8 is a characteristic diagram of a beaker test showing the relationship between alkalinity (PH value) and chemical cleaning rate in wash water having a detergent concentration of 1 times. This test observes the change of the cleaning rate when the alkalinity is changed by adding an alkali chemicals to the detergent liquid (washing water) of 1 times the detergent concentration produced by dissolving powder synthetic detergent with the detergent dissolved water of 0 ppm hardness. In alkalinity 10 (corresponding to washing water of detergent concentration 1 times), the cleaning rate is about 6%, but in alkalinity 11 (corresponding to detergent liquid of 10 times detergent concentration), it is increased to about 8%. Able to know.

9 is a characteristic diagram of a beaker test showing the relationship between the detergent concentration of the detergent liquid and the chemical cleaning power by oxygen. This test observes the relationship between the concentration of the detergent and the cleaning rate of the detergent solution produced by dissolving the powder compound detergent of oxygen mixture and the powder compound detergent of oxygen mixture without dissolving in 0 ppm of detergent dissolved water. It was found that the detergent solution in which the powder synthetic detergent containing enzyme was dissolved greatly increased as the detergent concentration increased.

Step 407

The main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 are opened and water supply of tap water (washing water) is started. The washing water is supplied up to the amount of water determined in step 402, but is stopped in order to detect the amount (wet pore) and the quality of the laundry 38 during the water supply. This interruption level is a level suitable for wet foam amount and quality detection set in the microcomputer 16a. The auxiliary water supply solenoid valve 22 is opened to clean the detergent dissolving vessel 21.

Step 408

The wet foam amount and the quality of the foam are detected to correct the washing water supply amount and to determine the washing process (washing process and rinsing process). This foam detection stops the water supply at a predetermined low water level, controls the electrically operated clutch mechanism 62 of the drive device 6 in the stirring mode or the washing mode, and applies the driving motor 61 with a short time to apply the stirring blade 4. Drive the drive device 6 by detecting the first characteristic (wet bubble amount) at the reached rotational speed during driving, and then supplying the wash water to a predetermined high water level after restarting the water supply. A short time force is applied to the electric motor 61 to rotationally drive the stirring blade 4, and the second characteristic at the attained rotational speed during driving is detected, and the laundry 38 is based on the difference between the first and second characteristics. Detect the quality of. This quality detection control is omitted when it becomes unnecessary by the initial setting. The time and water flow (intensity of mechanical stirring) in the washing and rinsing process are then determined according to the quality of the foam.

Step 409

The tap water is supplied up to the amount (water level) determined in step 402. By this water supply, the washing water is diluted with a high concentration of detergent solution to obtain a detergent concentration (1 times) desirable for washing. Thereby, the laundry 38 is in the state which 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 solution is diluted with tap water of high hardness, but since the detergent component penetrates the laundry at high concentration and acts on contamination, the cleaning effect of the detergent component is inhibited by these water supplies. There is nothing to be done.

Step 410

The drive device 6 is controlled to perform the washing process of washing water flow and washing time set in step 408. In this washing process, the drive device 6 controls the electric operation clutch mechanism 62 to the washing mode, and repeats the forward and reverse rotation of the drive electric motor 61 to clean the washing and dewatering tank 2 and the stirring blade 4. Repeat forward and reverse rotation.

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

Fig. 10 shows the relationship between washing time and washing degree. In the washing step, the washing and dewatering tank 2 and the stirring blade 4 are repeatedly rotated and reversed in the opposite direction in order to reduce the contamination adhered to the laundry 38 to exert a mechanical force on 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 dipping the high concentration detergent liquid in the laundry 38. That is, the washing time and the degree of washing when the washing step is performed by 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.

Since the washing removes the contamination from the laundry by the synergistic effect of the detergent chemical power and the washing machine mechanical force against the washing of the laundry, the washing degree is improved in accordance with the relationship between the washing time and the washing degree index shown in FIG. The conventional washing time is generally about 8 to 10 minutes, and the cleaning index at this time is 50.

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

Thus, after immersing a high concentration detergent liquid, 90 degree of washing | cleaning can be implement | achieved by going to the washing | cleaning process and performing stirring for about 8 minutes.

Accordingly, by adopting the washing method in which the high concentration detergent liquid is poured into the laundry 38, even if the washing time is less than 5 minutes, the contamination of the laundry 38 is better dropped than before. For this reason, even if it reduces the mechanical power of a laundry, it can provide the high-concentration washing system which improves washing power.

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

Fig. 11 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 performing the washing process with a large mechanical force. Since the mechanical force in the washing step is proportional to the magnitude of the stirring force (reverse rotation angle) 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 stirring are performed. The angle of rotation of the blade 4 is increased, the laundry tangle rate is increased. In this embodiment, since the required washing power can be obtained with a small mechanical force, the washing step can be performed at the laundry tangle rate of the characteristic curve 1101, and a laundry tangle rate of 10% or less can be realized.

That is, by adopting a high concentration washing method, the contamination of the laundry 38 is less likely to be reduced with a lower mechanical force than the conventional washing method, so that the mechanical strength of the washing machine can be reduced to reduce damage and entanglement of the laundry 38.

Step 411

The drain solenoid valve 33 is opened to drain the wash water to the outside.

Step 412

The main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 are opened, and rinsing water (tap water) is supplied to a predetermined amount of water. At this time (when water is rinsed for the final rinsing when rinsing a plurality of times), the auxiliary water solenoid valve 22a is also opened as necessary to inject the finishing agent.

Step 413

The drive device 6 is controlled to carry out a rinsing process. In the washing process by the high concentration washing method, since the amount of generation of the metal soap which increases the adsorption of the surfactant to the laundry 38 is suppressed, the rinsing performance is improved (about 1.3 times), and the predetermined amount is reduced with a small rinsing force (mechanical force). Rinsing can be performed.

Step 414

The drain solenoid valve 33 is opened to drain the rinsing water to the outside.

Step 415

With the drain solenoid valve 33 open, the electric operation clutch mechanism 62 of the drive device 6 is controlled in the dehydration / drying mode, and the drive motor 61 is driven at a high speed so that the washing and dehydration tank 2 and the stirring vane are operated. The water in the laundry 38 is centrifugally dehydrated by rotating (4) integrally at a high speed. In the state where this centrifugal dehydration is complete | finished, the laundry 38 is in the state stuck to the side wall of the washing | cleaning and dehydration tank 2, and was 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 and dehydration tank 2 and the stirring blade 4 at low speed. (26) is operated to suck air in the outer tub 5 from the air intake port 5a, and to supply the inside of the water cooling dehumidification duct 23 to the water cooling dehumidification duct 23 in the process of ascending the inside of the water cooling dehumidification duct 23. It cools and dehumidifies with cooling water, and it inhales into the circulation fan 26 via the downwind duct 25, and passes from the circulation fan 26 to the inlet port 30 through the ascending duct 27 and the heater 29. Circulating air which is sent, heated by the heater 29 and sucked in the opposite direction to the rotational direction of the washing / dehydrating tank 2 toward the inner wall surface in the washing-and-dehydrating tank 2, and washing and dehydrating. The laundry in the tank 2 is dried.

When the laundry 38, which has been centrifuged and dehydrated and attached to the sidewall of the washing and dehydrating tank 2, is warm-air dried, wrinkles are generated in the laundry 38, and thus, the stirring blade 4 is regularly reversed during the drying time. Rotate to dry the laundry (38) while moving.

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

In this embodiment, the wet water flow rate for the wet process in which the water is wetted by containing the laundry, the detergent dissolution water flow rate for dissolving the powdered synthetic detergent to generate the high concentration detergent liquid, or the dilute water supply for diluting the high concentration detergent liquid. Flow rate and quantity are set by the water flow rate (water flow path area) and water supply time of the main water solenoid valve 20 and the auxiliary water supply solenoid valve 22 which perform these water supply, but the actual water flow rate is a water source (water supply) Fluctuates by the water pressure. Therefore, the water flow rate of the main water solenoid valve 20 and the auxiliary water solenoid valve 22 is set based on the water flow rate at the lowest predictable water pressure, and the water level sensor 15 is monitored to a predetermined level. The actual water supply time at the time of water supply is measured, and the water pressure of a water source is calculated | required and stored by the arithmetic processing based on the measured water supply time, and when the said wet water supply, detergent dissolution water supply, and dilution water supply, the main water supply solenoid valve 20 and By intermittently opening and closing the auxiliary water supply solenoid valve 22 to intermittently supply water, flow rate control is performed so that the average value becomes a predetermined flow rate.

Although embodiment described above is fully automatic washing drying, when implementing with the washing machine which does not have a drying function, it can implement similarly by omitting the warm air circulation drying means in the above-mentioned embodiment, and its control process. That is, by omitting the warm air circulation drying means in the above-described embodiment and omitting the drying control processing step 416 executed by the control unit 16 in the control device, a fully automatic washing machine without a drying function can be realized.

In addition, the washing machine and the laundry dryer of the present invention may adopt different methods for washing and rinsing, respectively.

In the above-mentioned embodiment, although the vertical type washing and dewatering tank 2 was illustrated, it can also be set as the drum type which the horizontal washing and dewatering tank is generally called.

In addition, the stirring blade 4 located in the center of the washing and dewatering tank for forward and backward washing of the laundry is a pulsator type called a pulsator type with a blade attached to the disk, or the blade is washed by rotating the large blade within 360 degrees. An agitator blade called an agitator type can be used. Moreover, it can also be set as the structure which installed the pulsator shape stirring blade which moves a laundry to the bottom part of a washing | cleaning and dehydration tank integrated with this washing | cleaning and dehydrating tank.

In addition, the powder synthetic detergent used can also be replaced by the liquid synthetic detergent of the same detergent component.

Another embodiment of the invention is described.

Fig. 13 is a block diagram showing the electric system of the washing and dewatering tank.

And FLSs 16c4 to 16c11 for controlling the power supply to the cooling water solenoid valve 24a. This drive circuit 16c controls the conduction state of the FLSs 16c1 to FLS 16c11 in accordance with an instruction from the microcomputer 16a to perform power supply control to the subordinate load.

The microcomputer 16a includes a rotation sensor 61b of the drive motor 61, a position sensor 62c of the electrically operated clutch mechanism 62, a water level sensor 15 that detects a washing level in the outer tub 5, and humidity. By connecting to the sensor 40, the 1st, 2nd temperature sensors 41 and 42, the unbalance detection sensor 43, and the operation panel 14, and executing a control process program which was previously internalized, Input switch group 14a, water level sensor 15, rotation sensor 61b, position sensor 62b, humidity sensor 39, first and second temperature sensors 41, 42 and unbalance detection sensor 43 By acquiring a signal from the control circuit and controlling the driving circuit 16c, the processes of detection, generation of high concentration detergent liquid, wetting of laundry, generation and supply of high concentration detergent liquid (immersion), washing, rinsing, dehydration and warm air drying are performed. The progress thereof is displayed by controlling the display element group 14b of the operation panel 14. Here, when the unbalance detection sensor 43 rotates the washing and dewatering tank 2, the unbalance detection sensor 43 washes and dewatering tank 2 (outer tank 5 by unbalance distribution of the laundry 38 in this washing and dehydrating tank 2). It is a sensor that detects that)) vibrates significantly above a predetermined value.

The laundry dryer turns on the power switch 13, opens the outer lid 31 and the inner lid 32, puts the laundry 38 into the washing and dewatering tank 2, and puts the outer lid 31 and the inner lid on. When the washing start switch of the operation panel 14 is closed by closing (32), the control unit 16 operates the drive device 6 to operate the stirring blade 4 in a state in which the washing and dehydration tank 2 is stopped. By rotating, the amount of washing is detected, the amount of wash water and the corresponding detergent amount are determined, and the display element group 14b of the operation panel 14 is controlled to display it.

When the outer cover 31 is opened, a considerable amount of powder synthetic detergent and finishing agent is put into the detergent dissolving container 21, and when the outer cover 31 is closed, the auxiliary water supply solenoid valve 22 is opened to open the powder synthetic detergent. The tap water (detergent dissolved water) suitable for dissolving is supplied to the detergent dissolution container 21, and the detergent stirring electric motor 39 is operated to dissolve while stirring the powder synthetic detergent to produce a high concentration detergent liquid.

In the meantime, the tap water is washed by controlling the drive device 6 to open the main water feed solenoid valve 20 while rotating the laundry 38 by slowly rotating the washing / dehydrating tank 2 and the stirring blade 4 to rotate the laundry 38. Pour evenly over (38) to wet the laundry (38). The amount of water at this time is controlled to be such that the laundry 38 can be wetted evenly.

Subsequently, the auxiliary water supply solenoid valve 22 is opened to supply additional water to the detergent dissolution container 21 to supply a high concentration of the detergent liquid in the detergent dissolution container 21 to supply the water inlet 19 to the main water supply outlet. By opening the valve 20 and supplying it to the water inlet 19, the high concentration detergent liquid is diluted to a desired detergent concentration (range of 5 to 30 times) and controlled to be poured into the laundry 38. At this time, the washing and dewatering tank 2 and the stirring blade 4 are integrally and slowly rotated so that the high concentration detergent liquid is evenly poured on the laundry 38 and uniformly penetrates the laundry 38. The drive device 6 is controlled to rotate or stir the laundry 38 by rotating the stirring blade 4 while the 2) is stopped.

In this way, when the powdered detergent is dissolved in water, and the diluted detergent solution having a concentration of 5 to 30 times diluted is immersed in the laundry 38, the chemical cleaning power of the detergent component acts effectively on the contamination of the laundry 38. Increase the cleaning power. After the high concentration detergent solution is immersed in the laundry 38, the main water solenoid valve 20 and the auxiliary water solenoid valve 22 are opened and controlled so as to supply the washing water to a predetermined level, and then the washing and dehydrating tank 2 ) And the stirring blade 4 are rotated in the opposite direction to control the driving device 6 to execute the washing process for exerting a mechanical force on the laundry 38.

After the washing process is finished, the drain solenoid valve 33 is opened to drain the washing water to the outside, and the washing and dewatering tank 2 and the stirring vane 4 are integrally rotated at a high speed to centrifuge the washing water. The drive device 6 is controlled to perform intermediate dewatering to dewater. In the meantime, after the dehydration is completed, the drain solenoid valve 33 is controlled to be closed, and the main feed water solenoid valve 20 is opened to supply water to a predetermined rinsing level, and the washing and dehydration tank 2 is stirred. The drive device 6 is controlled to execute a rinsing process in which the blade 4 is rotated forward and backward in the opposite direction to apply a mechanical force to the laundry 38. This rinsing step is carried out as needed a plurality of times, and the auxiliary water supply solenoid valve 22a is opened at the time of water supply in the last rinsing to supply the finishing agent. After the rinsing step is finished, the drain solenoid valve 33 is opened to drain the rinsing water to the outside, and after washing, the washing and dewatering tank 2 and the stirring blade 4 are integrally rotated at high speed to rinse the rinsing water. The drive device 6 is controlled to perform final dehydration for centrifugal dehydration.

(6) to control and generate the circulating air which draws out the wet air in the outer tank 5 and the washing and dewatering tank 2 from the intake port 5a, and inhales in the washing and dewatering tank 2 from the inlet 30. The circulation fan 26 is controlled to operate so as to control the arithmetic solenoid valve 24a of the cooling arithmetic unit 24 to cool the circulating air in the water cooling dehumidification duct 23, and to the washing and dewatering tank 2. A warm air drying step of controlling the heater 29 to heat the inhaled air is performed.

Fig. 17 is a bottom view showing a part of the dryer cut out, Fig. 17 is a top view of a laundry dryer showing an outer tank and a circulating air path with the top cover removed, Fig. 18 is a longitudinal sectional side view of the seam collecting unit, and Fig. 19 is a top view showing the relationship between the outer frame and the outer tank. 20 is an exploded view of the outer tank top cover. A part of the description overlapping with the description of FIG. 12 is omitted.

The rotary drive device 6 includes a central output shaft 64 and a washing and dewatering tank to which a reversible drive electric motor 61, an electrically operated clutch mechanism 62, a sun gear reduction mechanism 63, and a stirring blade 4 are coupled to each other. And an outer output shaft 65 to which (2) is coupled. The sun gear reduction mechanism 63 includes a sun gear directly coupled to the drive electric motor 61, an inner gear and a planetary gear directly coupled to the outer output shaft 65, and a carrier directly coupled to the center output shaft 64. Then, by controlling the electric operation clutch mechanism 62 in the stirring mode, the drive motor is stopped in a state in which the inner gear (connected to the outer output shaft 65 and the washing and dewatering tank 2) of the sun gear reduction mechanism 63 is stopped. The rotational force of the 61 is decelerated through the sun gear, the planetary gear and the carrier to be transmitted to the center output shaft 64 to rotate the stirring blade 4 forward and backward, and the electric operation clutch mechanism 62 is controlled in the washing mode. The inner gear of the gear reduction mechanism 63 (connected to the outer output shaft 65 and the washing and dehydrating tank 2) is free to rotate, so that the rotational force of the drive motor 61 passes through the sun gear, the planetary gear, and the carrier. By decelerating and transmitting to the center output shaft 64, the stirring blade 4 is rotated forward and backward, and at the same time, the reaction force acting on the inner gear is transmitted to the outer output side 65 so that the washing and dewatering tank 2 is transferred to the stirring blade 4 and Rotate in the opposite direction, the electric operation clutch mechanism 62 By controlling in the dehydration / drying mode, the sun gear and the inner gear of the sun gear reduction mechanism 63 are directly connected to the drive motor 61, and the rotational force of the drive motor 61 is transferred to the center output shaft 64 and the outer output shaft 65. By passing through the washing and dehydration tank (2) and the stirring blade (4) is configured to rotate them integrally.

The vertical portion of the water-cooled dehumidification duct 23 in the circulation air passage is located along the outer tub 2 such that it is located at the end of the cylindrical outer tub 5, i.e., the closest part to the rear lid 1a of the outer frame 1. It is formed continuously by the periphery of the suction port 5a of the side wall of this outer tub 2, and is integrally formed with this side wall. The water-cooled dehumidification duct 23 is formed into a rectangular cross-sectional shape with a narrow inner length and wider width so as to be suitable for being placed in a narrow space between the outer tub 2 and the rear lid 1a. The wide rectangular water-cooled dehumidification duct 23 having a wide rectangular cross section is thus suitable for cooling and dehumidifying the circulating air because the wall surface is widened and the circulating air cooling wall is increased.

The vertical portion of the downcomer duct 25 is formed by integral molding on the side wall of the outer tub 5 so as to be in common with the water-cooled dehumidification duct 23 laterally adjacent to the water-cooled dehumidification duct 23. Since this position is separated from the rear lid 1a by the curvature of the outer tub 5, the air passage cross-sectional shape is formed so as to form an approximately square with a wider inner length and a narrower width, thereby controlling the expansion of the width of the circulating air passage. .

The vertical part of the rising air passage duct 27 is formed by integral molding on the side wall of the outer tub 5 so as to be a side wall common to the water-cooled dehumidification duct 23 adjacent to the transverse direction on the opposite side of the water-cooled dehumidification duct 23. . Since this position is separated from the rear lid 1a by the curvature of the outer tub 5, the air passage cross-sectional shape is formed so as to form an approximately square with a wider inner length and a narrower width, thereby controlling the expansion of the width of the circulating air passage. .
