The drying time is set by the input setting means 52.

  When the start button 52f is pressed to start the operation content set by the input setting means 52, the washing process is started in S1 (step 1) of the flowchart, and the water supply process is performed in S2 (step 2). After supplying a predetermined amount of tap water in the washing tub, the dirt component of the laundry starts to dissolve in the washing water by rotating the washing drum alternately in the forward rotation direction and the reverse rotation direction in S3 (step 3). When a predetermined time has elapsed in S4 (step 4), the dirt is detected by the dirt detecting means 54 in S5 (step 5).

  When there is little dirt on the laundry in S6 (Step 6), the operation content set by the input setting means 52 in the initial standby state by the user within a range in which basic performance such as washing performance and rinsing performance can be sufficiently secured. After changing to the operation content (saving course) in which the washing time and the number of times of rinsing are reduced, the washing process is performed until the operation content (wash time) newly set in S8 (step 8) is satisfied, and then S9 (step) In 9), the washing process is finished, and thereafter, the operation of the newly set operation contents (the number of times of rinsing, the dehydration time, and the drying time) is performed and finished by S10 to S12 (steps 10 to 12).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments. In addition, the same components as those in the background art are denoted by the same reference numerals and description thereof is omitted.

(Embodiment 1)
FIG. 1 is a schematic configuration diagram of a washing machine according to a first embodiment of the present invention, FIG. 2 is a cross-sectional view of a dirt detection unit, and FIG. 3 is a cross-sectional view as viewed from above the stain detection unit.

  In FIG. 1 to FIG. 3, reference numeral 1 denotes an outer box of the entire washing machine, in which an outer tub 2 is disposed, and a drum 3 as a washing tub is inclined upward from the horizontal direction inside the outer tub 2. It arrange | positions in the state which can be rotated with a rotating shaft. The drum 3 is rotated by a motor 4 connected to the back surface. The drum 3 is provided with a large number of water passage holes (not shown) on the outer peripheral surface, and functions as a washing tub, a dewatering tub, and a drying tub.

  A water intake 5 is connected to the lowest part on the rear side of the outer tub 2 provided at the rear end, and is connected to a drain pipe 7 that is opened and closed by a drain valve 6. A circulation path 9 connected to the discharge port 8 for discharging the washing liquid taken from the water intake port 5 to the drum 3 is communicated between the water intake port 5 and the drain valve 6. The washing liquid and the rinsing liquid can be circulated through the circulation path 9.

  The lateral flow path 9a formed in the horizontal direction of the circulation path 9 is provided with a soil detection means 10 for detecting the state of the washing liquid, and the washing liquid that has entered the circulation path 9 from the water intake 5 is in the horizontal direction. It is provided at a predetermined downstream distance L from the inlet flowing into the flow path 9a. The lateral flow path 9a may be provided with a slight inclination from the horizontal direction.

  The dirt detection means 10 is composed of a transmissivity sensor composed of a light emitting element 11 such as an LED and a light receiving element 12 such as a phototransistor, and is opposed to the left and right with the lateral flow path 9a of the circulation path 9 sandwiched from the outside. The lateral flow path 9a in the portion sandwiched between the light emitting element 11 and the light receiving element 12 is formed of a light-transmitting material, and the light emitted from the light emitting element 11 is circulated in the circulation path 9. The washing light is received by the light receiving element 12, converted into a voltage and output. For this reason, the dirt detection means 10 has a light-shielded sealed structure so that the light receiving element 12 does not receive light from the outside.

  The dirt detection means 10 is installed in a lateral flow path 9a in which the circulation path 9 is arranged in the horizontal direction with respect to the ground, and the light emitting element 11 and the light receiving element 12 are located near the center with respect to the vertical direction in the cross section of the circulation path 9. The washing liquid state is detected at a lower position that avoids the upper layer portion of the flow path cross section.

The light emission control of the light emitting element 11 and the capture of the output of the light receiving element 12 are performed by a control circuit (not shown) such as a microcomputer, and the output value from the light receiving element 12 is used as the permeability of the washing liquid passing through the circulation path 9. Processing is performed, and the washing process and the rinsing process are controlled based on the transmittance.

  The washing liquid in the washing process gradually becomes cloudy as the dirt from the laundry is dissolved by the detergent and stirring. For this reason, it is possible to determine the amount of dirt and the completion of cleaning by observing changes in the permeability of the detergent liquid and the permeability with time.

  Next, the operation | movement which detects the transparency of the washing machine of this Embodiment is demonstrated. By rotating the drum 3 at the time of washing or rinsing, the washing liquid in the drum 3 or the outer tub 2 enters the circulation path 9 from the water intake 5, and the lateral flow path of the circulation path 9 having the washing liquid state detecting means 10 is provided. Circulate to drum 3 through 9a. As a result, the water in the circulation path 9 is always equal to the washing liquid in the drum 3 and the outer tub 2.

  In the dirt detection means 10, for example, light is emitted from the light emitting element 11 every minute, and the output received by the light receiving element 12 is used as control of the washing process and the rinsing process as the permeability of the washing liquid at that time.

  Since the washing liquid is water containing a detergent, there are many bubbles. In particular, in the lateral flow path 9a where the dirt detecting means 10 is placed, bubbles are likely to rise and flow through the upper layer part, but the light emitting element 11 and the light receiving element 12 are placed in the lateral flow path 9a and the upper layer part of the flow path cross section is avoided. Therefore, the permeability of the washing liquid can be accurately measured without being affected by the bubbles.

  Further, if the dirt detection means 10 detects at the center position avoiding the upper layer part and the lower layer part of the lateral flow path 9a, the contaminants are contained in the washing liquid entering the circulation path 9 from the lower part of the outer tub 2. If it is included, most of it passes through the lower layer when flowing through the lateral flow path 9a, so that it is possible to detect the washing liquid with less contaminants flowing through the center position.

  Further, since the dirt detection means is provided at a certain downstream from the entrance of the lateral flow path 9a, the bubbles contained in the washing liquid that has entered the lateral flow path 9a flow downstream while floating upward. It is possible to detect a washing liquid with less air bubbles flowing below.

  As described above, by arranging the light emitting element 11 and the light receiving element 12 of the dirt detection means 10 on the left and right sides that are near the center with respect to the vertical direction in the cross section of the circulating water channel 9, the bubbles in the circulating channel 9 are always present. As a result, it is possible to measure the permeability of the washing liquid without being affected by the above, so that there is no risk of variation in the measurement of the permeability due to the number of bubbles in the type and amount of the detergent.

  FIG. 4 shows another example of the dirt detection means 10, in which the light emitting element 11 and the light receiving element 12 are inserted into the lateral flow path 9 a of the circulation path 9, and the light emitting element 11 and the light receiving element 12 flow in the lateral direction. It is located in the path 9a. According to this configuration, since the permeability of the washing liquid can be detected in the circulation path 9, the circulation path 9 does not need to use a light-transmitting material, and the wall of the circulation path 9 is contaminated. The light receiving level of the light receiving element 12 does not deteriorate, and the light emitting element 11 and the light receiving element 12 are simply inserted into the circulation path 9 to form a waterproof structure, and there is no need for a light-shielded sealed structure.

  Further, the dirt detection means 10 detects at a lower position avoiding the upper layer portion in the horizontal flow path 9a or at a central position avoiding the upper layer portion and lower layer portion in the horizontal flow path 9a. The light emitting element 11 and the light receiving element 12 of the sensor are provided outside the lateral channel 9a or in the lateral channel 9a.

The light emitting element 11 and the light receiving element 12 of the transmittance sensor are laterally arranged so that they can be detected at a lower position avoiding the upper layer portion in the lateral flow path 9a or at a central position avoiding the upper layer portion and the lower layer portion. When provided outside the flow path 9a, it is arranged facing the left and right direction, that is, in the horizontal direction, and when provided inside the horizontal direction flow path 9a, it is arranged in the vertical direction, that is, the vertical direction in addition to the horizontal direction. Is possible.

  FIG. 5 shows another example of the dirt detection means 10, which is a conductivity sensor having a pair of electrodes 13 a and 13 b immersed in the circulation path 9. A pair of electrodes 13a and 13b are inserted on the left and right sides of the path 9a, and the conductivity of the washing liquid flowing through the circulation path 9 is measured. The conductivity is measured by, for example, forming an RC oscillation circuit with the impedance of the washing liquid between the electrodes 13a and 13b and a capacitor on a control circuit (not shown), and outputting the change in the washing liquid impedance as a frequency change. Further, this may be converted into a voltage value.

  As a result, when measuring the conductivity of the washing liquid, it is possible to determine the type of detergent and the amount of detergent in the washing liquid, and also to determine the amount of dirt of the conductive component mainly composed of sweat that has melted from the laundry. The washing process and the rinsing process can be controlled.

  Even in the case of detecting the conductivity, the electrodes 13a and 13b are installed on the left and right in the lateral flow path 9a of the circulation path 9, and the state of the washing liquid flowing at the lower position avoiding the upper layer portion of the horizontal flow path 9a is detected. By doing so, it is possible to measure the exact conductivity of the washing liquid without being affected by the bubbles in the circulation path 9.

  FIG. 6 shows another example of the dirt detecting means 10, which includes a permeability sensor that detects the permeability of the washing liquid with the light emitting element 11 and the light receiving element 12, and a pair of electrodes 13 a and 13 b. A conductivity sensor for measuring the conductivity of the washing liquid is installed at the same time.

  By detecting the two states of washing liquid permeability and conductivity, for example, if the conductivity is lower than a predetermined value but the permeability is higher than another predetermined value, a liquid detergent is introduced. If the conductivity is higher than the standard value even if the permeability reaches the level equivalent to tap water, it will be judged that the rinse is insufficient and the rinse will be extended. If the rate falls below the reference value, it can be used for control such as ending the rinsing process.

  FIG. 7 is a system block diagram of the operation display unit 14. The control device 15 has a control means 16 composed of a microcomputer or the like, receives an input signal from the input setting means 17 and outputs it to the setting content display means 18, and the output signal of the dirt detection means 10 is the control means 16. Is input.

  After starting the operation course, the water supply valve (not shown) and the drain valve 6 are operated to sequentially enter and exit the water in the outer tub 2, drive the motor 4, and operate the heater, and the laundry. Wash (rinse, etc.), rinse, and dehydrate (and dry). The operation display unit 14 is disposed in the upper front portion of the outer box 1 and is provided at an easily operable position.

  Reference numeral 19 denotes an energy saving lamp as an energy saving display means that indicates the meaning that the user is operating more economically than the operation content set by the user using the input setting means 17, and uses green. Thereby, it becomes easy to associate images that contribute to energy saving by performing the saving operation. 20 stores the first operation content set by the input setting means 17 and information on whether or not the operation is more economical than the first operation content set by the input setting means 17 (with and without energy saving). Storage means. Reference numeral 21 denotes a sounding device such as a speaker as an energy saving notification means provided in the operation display unit 14 and is arranged in the vicinity of the energy saving lamp 19.

  Next, the operation of the present invention will be described with reference to the flowchart of FIG. A laundry (clothing) and an appropriate amount of detergent are put into the drum 3 of the washing machine, and the power is turned on by pressing the power switch 17e of the input setting means 17 on the operation display unit 14 in FIG. 7, which is called an initial standby state. The washing time setting switch 17a, the number of rinsing times setting switch 17b, the dehydration time setting switch 17c of the input setting means 17 and the drying time setting when having a drying function until the operation is started after the start button 17f is pressed. By operating the switch 17d, the operation content of each stroke can be set.

  Next, the details of the operation sequence set by the input setting unit 17, the operation content obtained based on the laundry stain detected by the stain detection unit 10, and the operation sequence actually performed will be described. As shown in the flowchart of FIG. 8, in the above-described initial standby state, the washing time setting switch 17a, the number of times of rinsing setting switch 17b, the dehydration time setting switch 17c, and the washing function set by the drying time setting switch 17d if a drying function is provided. When the operation is started by pressing the start button 17f to execute the time, the number of times of rinsing, the dehydration time, and the drying time, the washing process is started in S1 (step 1) of the flowchart.

  After supplying a predetermined amount of tap water into the drum 3 in the water supply process of S2 (step 2), the drum 3 is alternately rotated in the forward rotation direction and the reverse rotation direction in step S3 (step 3). When the dirt component starts to dissolve in the washing water and a predetermined washing time (5 minutes in the embodiment of FIG. 8) elapses in S4 (step 4), the dirt detection means 10 detects the dirt in S5 (step 5). .

  If there is little dirt on the laundry in S6 (step 6), the first set by the input setting means 17 in the initial standby state by the user within a range in which basic performance such as washing performance and rinsing performance can be sufficiently secured. The operation content of the “saving course” (in the embodiment of FIG. 8, the washing time of 15 minutes) is reduced rather than the operation content of FIG. 8 (washing time of 20 minutes in the embodiment of FIG. 8). If the washing time determined based on the dirt in S7 (Step 7) is smaller than the first operation content set by the user, the energy saving lamp 19 as the energy saving display means is turned on in S8 (Step 8), and S9a The information (with energy saving) on which the saving operation is performed in (Step 9a) is stored in the storage unit 20.

  On the other hand, if the washing time determined based on the dirt in S7 (step 7) is larger than the first operation content set by the user, the setting content such as the washing time is not changed, and the energy saving lamp 19 is turned on. Without storing the information (no energy saving) in S9b (step 9b), the storage unit 20 stores the information (no energy saving).

  Thereafter, when the washing time determined based on the dirt in S10 (Step 10), that is, 15 minutes changed from 20 minutes, the washing process is finished in S11 (Step 11), and the rinsing in S12 (Step 12) The process, the dehydration process of S13 (step 13), and the drying process of S14 (step 14) are executed.

  When the set series of processes is completed, information on whether or not the energy saving operation has been performed with the operation content stored in the storage unit 20 in S15 (Step 15) is called, and the saving operation is performed in S16 (Step 16) Performs sound saving notification by sounding from the speaker 21 in S17 (step 17). The energy saving notification is performed with contents suitable for energy saving notification by buzzer, melody, voice synthesis and the like. Then, the energy saving lamp 19 that has been turned on when the saving operation is performed in S18 (step 18) is turned off.

  At this time, the energy saving notification is made different from the operation end sound when the saving operation is not performed, so that the existence of the saving operation can be easily understood, and the saving operation can be performed even when the user is not near the washing machine. The result of whether or not it has been made can be easily notified.

  In addition, when the level of saving operation is set in multiple stages, it becomes possible to notify by changing the energy saving notification sound according to the level of saving operation, even if the user is not near the washing machine, The degree of saving operation can be easily notified.

  Further, by performing the energy saving notification by voice synthesis, the result of whether or not the saving operation can be performed can be notified more easily.

  As a result, the user can easily know whether or not he / she has been able to save electricity and water bills by actually running with a small amount of washing time and the number of times of rinsing for the originally set operation content. In addition, it is possible to increase the convenience that it is easy to realize a series of relations, such as how much laundry and how large and small the amount of dirt is, so that saving operation that contributes to energy saving is possible.

  In the present embodiment, a specific name and number for setting the contents of each process by the input setting means 17 will be described by the user, and a specific example of lighting the energy saving lamp 19 as an energy saving display means will be described. Although specific timing and specific timing for sound generation by the speaker 21 serving as an energy saving notification means have been described, this is not intended to limit the present invention.

  In the present embodiment, the first operation content set by the user using the input setting means 17 in the initial standby state is compared with the second operation content obtained based on the dirt detected by the dirt detection means 10. However, this is not intended to limit the present invention, and the number of times of rinsing or the time may be compared, and the dehydration time and drying time may be compared. Also good. Further, the determination may be made by comparing with the combination of the washing time and the number of times of rinsing.

(Embodiment 2)
FIG. 9 is a flowchart showing the operation of the control means of the second embodiment of the present invention, and FIG. 10 is the same time chart. The feature of this embodiment is that, when saving operation is performed, the energy saving display lamp 19 which is an energy saving display means is turned on when the open / close door 1a is opened after the operation is finished, and the speaker 21 which is an energy saving notification means is turned on. It is to pronounce and notify that effect. Other configurations are the same as those of the first embodiment, and the detailed description is the same as that of the first embodiment.

  As shown in the flowchart of FIG. 9, when the open / close door 1a is opened, information (whether energy saving / non-energy saving) is called in the driving operation stored in the storage means 20 in S15 (step 15). When the saving operation is performed in S16 (Step 16), the speaker 21 emits sound for a predetermined time in S17 (Step 17) and the energy saving lamp 19 is turned on.

  In S17 (step 17), after the energy saving display means and the energy saving notification means are activated and the sound output from the speaker 21 and the energy saving lamp 19 are turned on, the opening and closing door 1a is opened in S19 (step 19) for a predetermined time T1 ( For example, when 5 minutes elapses, the energy saving lamp 19 is turned off by S20 (step 20).

  Accordingly, the second operation content obtained based on the dirt level of the laundry detected during the actual washing operation is smaller than the first operation content set by the user using the input setting means 17 before the operation is started. The result of whether or not the saving operation was performed (to save electricity and water bills by reducing the washing time and the number of times of rinsing within the range where basic performance such as washing performance and rinsing performance can be sufficiently secured) It is possible to improve the convenience of operation by notifying the user accurately.

  In addition, it is possible to convey the result of whether or not the saving operation has been performed for an appropriate time at the timing when the user takes out the laundry.

  In addition, as shown in FIG. 10, the sound from the speaker 21 is shortly performed when the opening / closing door 1a is opened, and is intermittently notified at a predetermined interval until a predetermined time T1 (for example, 5 minutes) elapses. It is also possible.

  The energy saving display means and the energy saving notification means may be stopped when the door 1a is closed. In general, the user often leaves the washing machine when the laundry is taken out, and can accurately notify when the user is taking out the laundry.

(Embodiment 3)
