Description

Washing machine (2) Field of invention

The present invention relates to a washing machine that performs an operation control of washing and washing operation in response to contamination of a washing liquid.

Background of the invention

In the prior art, a technique for determining the end of washing is known by detecting the turbidity of the washing liquid, as disclosed in JP-A-57-66793 (Japanese Patent Publication No. 1).

In the case where the washing machine is temporarily stopped after the turbidity is detected, it is known that the sensitivity of the turbidity detector is readjusted. technology.

Further, in Japanese Patent Laid-Open Publication No. Hei 06-279 (Japanese Patent Publication No. 3), it is conventionally known that it is not mistakenly judged to be a change in turbidity of washing water due to dirt which is detached from clothing, or is due to swarf Techniques such as turbidity changes caused by floats to avoid erroneous detection of turbidity.

Fig. 5 is a graph showing changes in the output voltage of the turbidity sensor as the turbidity changes in the washing process of the washing machine described in Japanese Patent Publication 1. In Fig. 5, curve c is the case of water with low turbidity, and curve d is the change of the output voltage of the turbidity sensor in the case of water with high turbidity. In the case of high turbidity, the characteristic is switched at point D to obtain the voltage change of the curve e. In any case, as shown in Fig. 5, as the washing progresses, the dirt falls off from the clothes, the turbidity of the washing liquid increases, and the output voltage gradually increases. The technique described in Patent Document 1 detects that the output voltage is increased and the turbidity change is stable, and the end of the washing is determined.

Fig. 6 is a flow chart showing the control operation of the washing machine described in Patent Document 2. As shown in Fig. 6, the washing machine described in Patent Document 2 is in the middle of the washing operation, and the washing operation is temporarily stopped by inputting a stop signal from the temporary stopping unit, and then the operation is performed. The degree detector automatically adjusts the sensitivity again in response to the turbidity of the time. Thereby, for example, even if a new dirty laundry is additionally put into operation, the subsequent turbidity change can be accurately detected.

Fig. 7 is a graph showing the turbidity change of the washing water of the washing machine described in Patent Document 3. Figure 7 is a change in turbidity as shown by the solid line in normal time, but the case where the fluff enters the detection portion of the turbidity sensor is as shown by the broken line, and the output of the turbidity sensor is greatly reduced at time T2. To point P. In this case, the calculated value ΔVT ' of the turbidity change of the washing water at time T1 is larger than the calculated value ΔVT at the normal time. Therefore, the execution time of the washing stroke is set to be longer than the normal time (end time) as indicated by the end time T4. In the washing machine of Patent Document 3, the turbidity detection is performed before the predetermined time T4 is set at the end time T4, and the washing stroke is ended when the rate of change is equal to or less than a predetermined value.

That is, the actual turbidity of the washing water is as shown by the output at the normal time, and the end level can be determined without waiting for the error end time T4. When the swarf enters the turbidity sensor detection portion, the standard determination is terminated from the predetermined time (for example, 2 minutes) at the end time T4, so the end point at the normal time is known by the check of the end criterion, and the shortest is over. The washing stroke can be ended before the predetermined time of time T4 (for example, time T3). Therefore, when a foreign matter such as a lint-like swarf is accidentally attached to the turbidity detecting unit, excessive rinsing can be avoided while avoiding a decrease in turbidity.

However, as in the prior art, when the turbidity is detected, it is necessary to preliminarily supply the water to the rated water level in the washing and dewatering tank at the time of washing. That is, the state in which the lotion is dissolved in the washing water is also detected as the turbidity in the initial state including the stain dissolved in the washing water. Therefore, it takes time to measure the turbidity, and the detection accuracy of the turbidity also becomes a problem.

Moreover, in the prior art, when it is desired to detect the type of the lotion and set the washing course or the washing course after controlling the type of the lotion, it is difficult to detect the turbidity after the water is supplied to the rated water level. .

Moreover, the warm air blowing portion 61 is constituted by the circulation air receiving chamber 59, the drying fan 55, the heater 56, the warm air circulation path 57, and the upper bellows-shaped hose 58.

A temperature detecting unit 62 is provided on the inlet side of the warm air circulation path 57, and a temperature detecting unit 63 is provided on the outlet side to detect the circulating air temperature at the time of the drying cycle.

In the circulation air receiving chamber 59, a filter 64 is provided. The circulating air is circulated through this filter 64. Capture cotton swarf from the clothing category.

The outer tank 43 is provided with a tank cover 65 that seals the upper surface of the outer tank.

A support member 71 such as a warm air blowing portion 61 or a water supply valve 70 is provided inside the rear portion of the upper casing 68.

The water supply valve 70 is composed of a plurality of valves having two or more water passages that may be switched. The water supply valve 70 is supplied with water by a tap water or a bathtub water absorbing mechanism (not shown) or the like. The water passage of one of the water supply valves 70 is configured such that the opening area of the valve or the discharge port area on the side of the washing hose 72 is reduced to allow a small flow of water to flow out. The water path of one of the water supply valves 70 is connected to the cleaning pipe 77 of the drain pipe 75 formed at the outer bottom of the outer tank 43. The other water passage of the water supply valve 70 is configured such that the opening area of the valve or the discharge port area on the side of the cleaning hose 72 is increased to allow a large flow of water to flow out. The other water passage of the water supply valve 70 is configured such that the water supply member (not shown) or the like provided in the support member 71 is connected to the inner tank 44 as washing water.

At the bottom of the outer tank 43, a drain valve 74 for draining water in the outer tank 43 is provided, and the drain valve 74 is connected to the heat exchange conduit 52 and the connecting duct 53 by a drain conduit 75. The drains from the connecting duct 53 and the heat exchange duct 52 are guided to the drain duct 75 and the drain valve 74, and are drained from the drain hose 76 to the outside of the machine. Further, as described above, in the drain duct 75, the cleaning pipe 77 in which the pipe is connected to one end of the washing hose 72 of the water supply valve 70 is formed.

Further, in the drain duct 75, a turbidity detecting unit 92 is attached to the upstream side of the drain valve 74 to illuminate and receive light, and the turbidity of the washing water is detected by the degree of transmission and the rate of change to detect the degree of contamination of the clothes.

In the vicinity of the bottom of the outer tank 43, a conductivity detecting portion 78 (water level detecting portion) having an electrode 94 for detecting the presence or absence of water or a type of lotion is provided, and the conductivity of the washing water is detected. Since the conductive coefficient detecting portion 78 is located below the bottom of the outer groove 43 and below the upper surface of the outer peripheral portion of the rotary disk 46, the swirling water flow of the rotary disk 46 is less likely to be affected, so that the conductive coefficient can be stably detected. Further, in the present invention, the conductivity detecting portion 78 is used for detecting the water level in the vicinity of the bottom of the outer tank 43, so that it is also possible to use the water level detecting portion of another structure.

Further, an air pocket 95 is formed in the outer peripheral wall of the outer tank 43, and the air pocket 95 is connected to the water level detecting portion 90 constituted by a pressure sensor or the like through the air tube 96. By the water level detecting unit 90, the water level of the plurality of stages can be detected based on the water pressure of the washing water supplied to the inside of the outer tank 43 by the water.

The cooling blower 79 is attached to the side surface of the casing 41, and blows air so as to surround the inside of the cooling casing 41, the groove 43, the heat exchange duct 52, and the like.

The control device 80 is integrally formed, and is disposed substantially perpendicularly (that is, approximately perpendicular to the bottom surface of the casing 41) to the rear surface portion (back cover) 81 of the casing 41. But about vertical includes vertical. A cooling blower 79 is provided below the control device 80. The control device 80 is covered and protected by a cover 82.

An operation display unit 85 composed of an input setting unit 83 and a display unit 84 of a second drawing to be described later is provided on the front surface of the upper housing 68.

In the circuit block diagram of Fig. 2, the control device 80 controls the motor (drive unit) 48, the clutch 49, the drying fan 55 and the heater 56 constituting the warm air blowing portion 61, and the heater 56, The operation of the drain valve 74, the cooling blower (cooling unit) 79, the water supply valve 70, and the water suction pump 91, and the control unit 87 for controlling each stroke of the washing, washing, dehydrating, and drying, and the sterilization/deodorization stroke .

The control unit 87 is constituted by a microcomputer. The control unit 87 starts the operation from the commercial power source 88 by supplying power to the ON of the power switch 89. The control unit 87 inputs the outputs of the cloth amount detecting unit 93, the water level detecting unit 90, and the temperature detecting units 62 and 63, and displays the setting contents on the display unit 84 based on the contents set by the input setting unit 83 by the user input. . Further, the control unit 87 controls the motor 48, the clutch 49, the drying fan 55, the heater 56, the drain valve 74, the cooling blower 79, and the water supply by the load driving unit 86 including a bidirectional thyristor, a relay, or the like. The operation of the valve 70, the water suction pump 91, and the like, and the respective strokes of washing, washing, dehydrating, and drying are controlled. Further, the operation setting unit 85 is constructed by the input setting unit 83 and the display unit 84.

Further, the control unit 87 detects the conductivity of the washing liquid obtained from the conductivity detecting unit 78, the degree of light transmission obtained from the turbidity detecting unit 92, and the rate of change thereof, and detects the presence or absence of the washing water or the type of the lotion or The degree of soiling of clothing, etc., controls each trip.

When the temperature detected by the temperature detecting unit 63 reaches the first predetermined temperature (for example, 110 ° C), the control unit 87 turns off the heater 56 and lowers the second predetermined temperature according to the temperature of the temperature detecting unit 62. For example, at 2 deg), the heater 56 is operated to adjust the temperature of the circulating air.

In the above configuration, in the present embodiment, the basic operation from the washing and washing to the dehydrating stroke will be described in accordance with the operation control contents of the washing liquid.

Fig. 3 is a table showing the sequence of washing and dehydrating of the washing machine in the first embodiment of the present invention. Figure 4 is a flow chart of the control from washing to washing.

In the sequence chart of Fig. 3, the basic operation is constituted by a washing stroke, a washing (1) stroke, a washing (2) stroke, and a dehydrating stroke. In the flowchart of Fig. 4, during the washing course, the user opens the outer cover 69, opens the middle cover 66, puts the clothes into the inner tub 44, and sets the operation path to the input setting unit 83 to start the operation (S101). Thereby, the cloth amount detecting unit 93 detects the amount of the input (S102). The control unit 87 determines the water level, the washing amount, and the subsequent determination of the order in accordance with the amount of cloth, and displays it on the display unit 84 (S103).

At the same time, the water supply valve 70 that operates the small flow rate starts the feed water (feed water b) to the side of the cleaning hose 72, and supplies the water amount from the cleaning pipe 77 to the drain pipe 75, and the water amount of the drain pipe 75 is filled for a predetermined time. (S104). In addition, the turbidity D0 of the tap water of the water supply is detected by the turbidity detecting unit 92, and the determination of the turbidity D0 is performed (S105), and the data is input to the control unit 87.

Here, the reason why only the small flow side feed water of the water supply valve 70 is supplied to the drain duct 75 (feed water b) is as follows. When the water supply valve 70 is operated to supply the tap water to the inner tank 44 by the water supply hose 73 (water supply a), the tap water is retained in the drain duct 75 by the dirty clothes, so that the clothes may not be dirty. Detect the turbidity of the correct tap water. However, when a small amount of water (water supply b) is supplied from the side of the cleaning tube 77, it is possible to detect the correct turbidity which cannot be mixed by the dirt such as clothing.

In addition, the water level can be set from the level 1 to the level 9 to increase the water level. The level 3 is lower than the upper surface of the outer peripheral portion of the turntable 46. Further, from the level 4 to the level 9, the water level of the normal washing and stirring b and the washing and stirring c described later is performed in accordance with the amount of the cloth. Level 9 is the highest water level. In addition, FIG. 3 and FIG. 4 show an example of a case where a large amount of cloth is detected and a high water level of level 9 is detected.

Next, the user inputs the lotion according to the display of the washing amount (S106), or the lotion is automatically input although not shown. Thereby, the feed water b, that is, the small flow rate of the water supply valve 70 is operated, and the water supply pipe 72 and the cleaning pipe 77 are cleaned, and the water is supplied from the lower side to the level 1 through the drain pipe 75 and the connection duct 53 ( S107). The level 1 is about 100 mm lower than the upper surface of the outer peripheral portion of the turntable 46, and the conductive coefficient detecting portion 78 is immersed in the water level of the water, and the water level is detected by the conductive coefficient detecting portion 78 (S108), and the water supply is stopped (S109).

Further, the water level detecting unit 90 described above is said to detect the water pressure at which the air pockets 95 provided in the outer tub 43 are pressed, and the washing machine is generally used in an inexpensive manner. In this manner, it is necessary to correctly detect the water level of the lowest level which is about 100 mm lower than the outer peripheral portion of the rotary disk 46, because the water pressure is very small, so that it is difficult. However, when the water is in contact with the electrode 94 of one of the pair of the conductivity detecting portions 78, the water level at the lowest level (level 1) can be accurately detected by the conductivity detecting unit 78.

Next, when the drain valve 74 is closed, the clutch 49 of the transmission mechanism portion is switched to the dehydration side, and the power of the motor 48 is transmitted to the inner groove 44 by the dewatering shaft to rotate, and the inner groove 44 and the rotary disk are rotated. 46 is rotated together at a low speed of about 100 r/min (slot rotation operation) (S110). The washing liquid in the tank is gradually rotated between the inner tank 44 and the outer tank 43 due to the centrifugal force, so that the washing liquid does not adhere to the dirt of the clothes, and the lotion can be sufficiently dissolved. Then, it is stopped (S110x) to perform turbidity detection, and the turbidity D1 is determined (S111). In other words, the initial value of the turbidity of the washing liquid is detected by the turbidity detecting unit 92, and the data is input to the control unit 87. Thereby, the type of the lotion such as the powder lotion or the liquid lotion is controlled by the control unit 87 by the comparison (D1 - D0) of the turbidity D1 and the turbidity D0 (S112).

Next, while the water supply is level 2, the drain valve 74 is closed, the clutch 49 of the transmission mechanism portion is switched to the dehydration side, and the power of the motor 48 is transmitted to the inner groove 44 by the dewatering shaft to rotate. The inner groove 44 is rotated together with the rotary disk 46 by about 35 r/min of the lower speed (water supply/groove rotation) (S111x). Then, after stopping (S111y), the water is supplied to level 3 (S113), and the power of the motor 48 is transmitted to the rotary disk 46 by the clutch 49 of the transmission mechanism portion, and the rotary disk in which the rotary disk 46 is rotated is executed. Stir a (S113x). Further, the water is supplied to level 5 (S114), and the rotary disk a stirring is performed (S115). The water level detection of the plurality of levels 2 or more at the time of the water supply is performed by the pressure type water level detecting unit 90.

By this action, the water level is lower than the rated water level (here, the level of water set by the cloth level is detected by the cloth amount). In this case, the water level is lower than the highest water level (level 9) by 4 levels. The lotion is stirred at a high concentration, the foaming is also sufficiently carried out, and the dirt of the clothes is also dissolved in the washing liquid. Then, the turbidity of the washing liquid is stopped (S115x) and detected by the turbidity detecting unit 92, and the determination of the detected turbidity D2 is performed (S116). In other words, the turbidity D2 of the washing liquid is detected by the turbidity detecting unit 92, and the dirt of the clothing is large or the data is input to the control unit 87, and the turbidity D0 is determined by the control unit 87, and the turbidity D1 is determined. When the values are combined, the order of the next description can be calculated (S117).

From the calculation result, it is possible to determine whether or not the time of washing and stirring b (S119) may be shortened, and whether the time of washing and stirring c (S123) in the washing course may be shortened, and the subsequent order may be determined. That is, when it is judged that it is a liquid lotion, since a liquid lotion is easy to remove by a foam, it can shorten the washing-cleaning time of the washing|cleaning-c Further, if the stain of the clothing is determined to be smaller than the predetermined amount, the time during which the washing and stirring b is determined by the washing amount can be shortened by the amount of the cloth to be detected.

When the order is determined, the water supply valve 70 that operates the large flow rate starts to supply water to the inner tank 44 by the water supply hose 73 to the rated water level, and the water supply to the highest water level (level 9) in the case of Fig. 3 (S118). When the water supply is completed, the washing and stirring b at the time of the determination is started (S119), and the rotary disk 46 is rotated, and the clothes are caught by the stirring projections 51 of the rotary disk 46, and are pulled into the center portion. The clothes of the lower portion of the center of the inner groove 44 are pushed up by the upper portion of the inner groove 44 by the clothes that are pulled in. The clothes in the inner tank 44 are stirred in this manner, or the mechanical force acting on the inner wall of the inner tank 44 or the contact with the rotary disk 46, and the flow force by the water flow, and the dirt contained in the clothes is dissolved in the washing. The turbidity of the wash water in the water changes sequentially.

After the washing and stirring b of the washing stroke is started at a predetermined rated water level (grades 6 to 9), the turbidity detecting unit 92 performs turbidity detection of the washing liquid, and the determination of the turbidity D3 is performed (S120). In other words, the turbidity D2 determines whether or not the control based on the detection is reasonable is performed in the control unit 87 (S121), and based on the result, the washing time for the subsequent washing and stirring b (S122) is corrected, or the washing is performed (1). The number of times or time of washing c (S123) and washing (2) stirring c (S124).

The correlation between the determination of the turbidity D0 to D3 and the detection contents, the water level detecting unit, and the water level in each step described above is shown in Table 1.

In the washing (1) stroke of the secondary stroke, first, the drain valve 74 is opened to drain the water in the inner tank 44 by the drain hose 76. Thereafter, the clutch 49 of the transmission mechanism portion is switched to the dehydration side, and the power of the motor 48 is transmitted to the inner tub 44 by the dehydration shaft to be rotated, and the centrifugal force is applied to the clothes to separate the moisture from the clothes. After the motor 48 and the clutch 49 are turned off, the water supply valve 70 that operates the large flow rate in the water supply a is supplied with water to a high water level, and the motor 48 is driven again, and the washing liquid is washed out from the clothes (1). (S123).

The cleaning (2) stroke, that is, the final washing stroke, is performed in the same manner as the washing (1) stroke, and after completion, the washing is started (2) stirring c (S124).

In addition, the washing (1) stroke may be omitted depending on the degree of soiling of the clothes or the amount of the clothes.

In the dehydration step, first, after the completion of the washing, the drain valve 74 is opened to drain the water in the inner tank 44 by the drain hose 76. Thereafter, the clutch 49 of the transmission mechanism portion is switched to the dehydration side, and the power of the motor 48 is transmitted to the inner tub 44 by the dehydration shaft to be rotated, and the centrifugal force is applied to the clothes to separate the moisture from the clothes.

Although the order table in Fig. 3 is omitted, the clutch 49 is switched to the washing side drive motor 48 and transmitted to the rotary disk 46 during the drying stroke after the dehydration stroke, so that the rotary disk 46 is rapidly rotated forward and reversed, and the decanter is attached. The clothes on the inner wall of the inner groove 44 are peeled off. Then, the rotary disk 46 is rotated forward and reversed, and the stirring projections 51 are used to hook and stir the clothes, and the warm air is blown to the warm air by the warm air blowing unit 61 formed by the drying fan 55 and the heater 56. The wind blasts the hole 60. The warm air blown into the inner tank 44 by the warm air discharge hole 60, after evaporating water from the clothes, exits from the inner tank 44 to the inner side of the outer tank 43, and then passes through the connection duct 53 from the drain path port 54 to the heat exchange duct 52. .

When the moisture of the clothing contains the warm air of moisture and passes through the inner wall of the outer tank 43 or the heat exchange duct 52, the outer air 43 is supplied by the outside air of the cooling blower 79 provided on the side surface of the casing 41 or The outer wall of the heat exchange conduit 52 is cooled, and dew condensation of moisture occurs inside the outer tank 43 or the heat exchange conduit 52. That is, the humid warm air is dehumidified, enters the circulation air receiving chamber 59, passes through the filter 64, and then returns to the drying fan 55. The clothes in the inner tank 44 can be dried by circulating the wet air in this circulation path.

As described above, in the present embodiment, the control unit 87 shown in Table 1 detects the turbidity D0 of the tap water by the turbidity detecting unit 92 by supplying the tap water only inside the drain duct 75. After the application of the lotion, the water supply valve 70 is operated, and the water supply valve 72 and the drain pipe 75 are connected from the lower side of the outer tank 43 to the outer tank 43 at a lower water level than the outer circumference of the rotary disk 46. (Grade 1), the washing water which is not contaminated by clothing is detected by the conductivity detecting unit 78 provided at the low position of the outer tank 43, and the turbidity detecting unit 92 detects the turbidity of the washing liquid of the lowest level water level. D1. The type of the lotion is determined by using the turbidity D0 and the turbidity D1, and the liquid lotion or the powder lotion has a turbidity comparison of a special electrolyte or the like.

Thereby, the type of the lotion can be determined from the state of the washing water in which the dirt of the clothing is hardly eluted, so that the type of the lotion can be accurately determined in a short time, and the subsequent stroke can be controlled.

Further, the water level detecting portion used by the washing machine generally adopts an air cavity provided in the outer tub 43 and a so-called pressure sensor method for detecting the water pressure under pressure, and is effective in performing a plurality of water level detecting points. However, since the water level is detected, it is necessary to correctly detect the lower water level on the outer peripheral portion of the rotary disk 46, which is difficult because the water pressure is very small. However, in the configuration of the present embodiment, when the water level is detected by the conductivity detecting unit 78, when the water touches the electrode of the conductivity detecting unit 78, the water level reaching the lowest level can be accurately detected. Therefore, the turbidity detection of the lotion liquid can be performed without contacting the clothes and the dirt adhering to the clothes.

Further, as shown in the determination column of the turbidity D2 in Table 1, the control unit 87 can agitate the high concentration of the lotion at the water level (grades 2 and 3) lower than the rated water level in the turbidity detecting unit 92. The turbidity D2 of the washing liquid after the dissolution of the clothes from the clothes was detected.

Therefore, in the present embodiment, it is not necessary to take time to supply the washing water to the rated water level and then detect the turbidity, and at the early stage of the stroke, the turbidity is determined to determine the degree of soiling, to set the washing time or to clean up.
