Description

washing machine

The invention relates to a device for automatically putting in lotion and a washing machine installed with the device.

In lotions, there are powder lotions, liquid lotions, concentrated liquid lotions, etc., and their solubility in water is different. Therefore, for example, for powder lotions that are less likely to dissolve than liquid lotions, it is better to lengthen the dissolution time of the lotion to fully dissolve. On the other hand, for liquid lotions that are easier to melt than powder lotions, it is better to shorten the time for the lotion to melt, shorten the overall operating time, and reduce the power consumption of the lotion dissolving means (circulation pump).

In addition, depending on the type and amount of detergent to be injected, appropriate washing operation, washing operation, etc., are required to shorten the total time from the beginning to the end of washing, and to save energy and water. For example, a lotion that can perform the cleaning operation once is already commercially available. For this kind of lotion, it is better to change the operation content of the washing operation and the washing operation. Furthermore, for example, when it is determined that the user's clothes are less contaminated and a smaller amount of detergent than a predetermined amount is injected, it is better to change the operation content of the washing operation and the washing operation.

Inside the tank 42, a bottom surface that is inclined so as to descend toward the discharge port 49 is provided. In addition, the discharge port 49 is provided with a mesh-like tank net 48 with fine holes. Therefore, the washing machine 1 can prevent foreign substances from flowing into the conveyance path 53 (refer to FIG. 6) even if foreign substances are mixed into the inside of the tub 42.

<Pushing operation of the washing treatment liquid to the second input section (automatic input section)> The washing machine 1 of the present embodiment has a structure in which the washing treatment liquid can be easily injected into the second injection portion 32 (automatic injection portion, injection port) as described below. Here, first, with reference to FIG. 11A, an example of a case where the washing machine 101 of the comparative example is injected into the second injection portion 32 (automatic injection portion) will be described. After that, an example of a case where the washing machine 1 of the present embodiment is injected into the second injection portion 32 (automatic injection portion) with reference to FIG. 11B will be described. FIG. 11A is an explanatory diagram showing the state of input of the washing treatment liquid in the washing machine 101 of the comparative example. Fig. 11B is an explanatory diagram showing the state of input of the washing treatment liquid in the washing machine 1 of the present embodiment.

In addition, the washing machine 101 of the comparative example shown in Fig. 11A is similar to the conventional washing machine, and is the second arranged between the water supply unit 20 (water supply means) and the first input unit 31 (manual input unit). The device of the input unit 32 (automatic input unit).

As shown in FIG. 11A, in the washing machine 101 of the comparative example, the 2nd input part 32 (automatic input part) is arrange|positioned behind the 1st input part 31 (manual input part). In the washing machine 101 of this comparative example, when the user puts the washing treatment liquid into the second input part 32, the frame 11 collides with the body part (or the bottom part) of the replenishing container 91 for the washing treatment liquid. Therefore, in the washing machine 101 of the comparative example, it is necessary to arrange the discharge port of the replenishment container 91 at a relatively high position above the second input section 32 and to put the washing treatment liquid into the second input section 32 in this state. In the washing machine 101 of this comparative example, since the washing treatment liquid is injected into the second input section 32 from a relatively high position, there is a possibility that the washing treatment liquid cannot be injected into the second input section 32 intelligently and overflows. As a result, in the washing machine 101 of the comparative example, there is a possibility that the periphery of the second input portion 32 may be soiled by the water washing treatment liquid.

In this regard, as shown in FIG. 11B, in the washing machine 1 of the present embodiment, the second input section 32 (automatic input section) is arranged in front of the first input section 31 (manual input section). In the washing machine 1 of this embodiment, when the user puts the washing treatment liquid into the second input part 32, the frame 11 does not interfere with the body part (or the bottom part) of the replenishing container 91 for the washing treatment liquid. Therefore, in the washing machine 1 of the present embodiment, the discharge port of the replenishing container 91 can be directed to the second input portion 32 to input the washing treatment liquid into the second input portion 32. In the washing machine 1 of this embodiment, since the washing treatment liquid is injected into the second input section 32 from a relatively low position, the washing treatment liquid can be wisely injected into the second input section 32 without overflowing. As a result, the washing machine 1 of the present embodiment can prevent the area around the second input portion 32 from being soiled by the washing treatment liquid.

<The arrangement relationship between the input port cover (1st cover) and the tank storage cover (2nd cover)> Hereinafter, with reference to Fig. 12, the arrangement relationship of the input port cover 43a and the tank storage cover 15 will be described. Fig. 12 is an explanatory diagram showing the arrangement relationship between the input port cover 43a (first cover) and the tank storage cover 15 (second cover).

As shown in FIG. 12, the washing machine 1 is provided with the input port cover 43a and the tank storage cover 15 in the upper front part of the housing|casing 11. As shown in FIG. The inlet cap 43a is a first cap that seals the second inlet 32. The tank storage cover 15 is a second cover that is larger than the input port cover 43a and covers the upper side of the input port cover 43a. The inlet cover 43a (first cover) and the tank storage cover 15 (second cover) are each configured to be openable and closable from the front to the back in the vertical direction (refer to Figs. 2 and 3).

As shown in Fig. 12, the tank storage cover 15 (second cover) is arranged at a position where it abuts against the input port cover 43a (first cover) when it is closed. When such a tank storage cover 15 is locked, assuming that the input opening cover 43a is opened, it may abut with the input opening cover 43a to automatically close the input opening cover 43a. In other words, the washing machine 1 assumes that the user forgets to close the insertion opening cover 43a, and the user can automatically close the insertion opening cover 43a by closing the tub storage lid 15.

The oscillating circuit 39 sends a signal corresponding to the electrical conductivity between the electrodes to the microcomputer (hereinafter referred to as the microcomputer) 110 of the control device 100, and the characteristic is changed by the electrostatic capacity of the constituent part, which is the capacitor, making it easy to read The resistance value field of the water quality changes.

FIG. 14 is a functional block diagram illustrating the configuration of the control device 100 of the washing and drying machine of this embodiment. The control device 100 is configured with a microcomputer 110 as the center. The microcomputer 110 is provided with an operation mode pattern database 111, a process control unit 112, a rotation speed calculation unit 113, a laundry weight calculation unit 114, a conductivity measurement unit 115, and a detergent amount/wash time determination unit 116 , And the lotion state determination section 117, the foaming determination section 118, and the washing treatment liquid input determination section 119.

The microcomputer 110 has a function of calling the operation mode pattern in the operation program input from the operation switch 14 from the operation mode pattern database 111 to start washing and drying. The process control unit 112 has a function of operating and controlling each process of the washing process, the cleaning process, the dehydration process, and the drying process based on the operation mode pattern called from the operation mode pattern database 111.

In addition, the process control unit 112 is provided with: driving and controlling the motor 23a of the driving device 23 through the motor driving circuit 121, switching the clutch mechanism 23b through the clutch driving circuit 122, and turning on/off the heater switch 123 On (OFF) control functions to control the energization of the heater 71, control the fan 72 through the fan drive circuit 124, drive and control the circulation pump 17 through the circulation pump drive circuit 125, and drive and control the transport pump 46 through the transport pump drive circuit 126 .

As the weight of the clothes increases, the load for rotating the water tank 21 becomes larger, and the motor current flowing in the motor 23a needs to be increased. Therefore, the weight of the clothes can be calculated from the motor current and the rotation speed of the motor 23a.

The conductivity measuring unit 115 has a function of measuring the conductivity of tap water and washing liquid using the detected value from the water quality sensor 35.

The foaming determination unit 118 has a function of determining the number of rotations of the motor based on the state of the washing liquid determined by the conductivity measurement unit 115 and the lotion status determination unit 117 and the amount of water. The details will be described later.

The washing treatment liquid input judging unit 119 is an operation mode pattern with the setting ON/OFF (OFF) of the washing treatment liquid input from the operation switch 14 is summoned from the operation mode pattern database 111, based on The amount of detergent determined by the detergent amount/washing time determining unit 116 is a function of controlling the conveyance pump 46 by the conveyance pump drive circuit 126.

Next, referring to Fig. 15, the operation process of the washing and drying machine of this embodiment will be described. Fig. 15 is a process diagram illustrating the operation process of the washing operation (washing-washing-dehydration) of the washing-drying machine of this embodiment.

In step S1, the process control unit 112 receives input (program selection) of the selection of the program of the operation process and the setting (ON/OFF) of the water washing treatment liquid input. Here, the user throws water and laundry into the water tank 21. When the user operates the operation switch 14, the process control unit 112 rotates the rotary wing 21 b, and the laundry weight calculation unit 114 of the microcomputer 110 calculates the cloth amount for the laundry before water injection.

In step S2, when the process control unit 112 contains air in the hose connected to the water supply unit 20, the compressed air is discharged into the outer tank 22 together with the tap water.

In step S3, the detergent amount/washing time determination unit 116 displays the amount of detergent that should be put in and the time required to complete the washing on the operation panel 14 based on the amount of cloth, the temperature of tap water, and the hardness of the water. . In addition, the water temperature and water hardness of the tap water are those detected in the previous washing operation (step S30) and stored in the detergent amount/washing time determining unit 116. The water temperature and water hardness of the tap water do not change drastically every day, but only gently change. Therefore, the water temperature and water hardness of the tap water measured during the previous washing can be used to determine the washing amount. In addition, during the first operation after the washer-dryer is installed, it is an initial value (for example, water temperature of 15°C, hardness of 120 ppm) at which water washing performance does not deteriorate.

And in step S1, as long as the water washing treatment liquid input setting is ON, in step S3, according to the detergent amount determined by the detergent amount/washing time determining unit 116, the transfer pump drive circuit 126 transfers The pump 46 is controlled to supply the water washing treatment liquid to the first input portion 31 through the arrangement of the delivery path 53.

In step S4, first, the process control unit 112 opens the valve of the water supply unit 20, supplies lotion and water to the first input unit 31 and the outer tank 22, and closes the valve of the water supply unit 20 when the water level reaches a predetermined water level. In addition, when water is supplied to the first input unit 31, because the first water supply path 51 and the second water supply path 52 are branched, the washing treatment liquid remaining in the conveyance path 53 can be conveyed to the first input unit 31.

In step S5, the temperature of the supplied lotion-containing water is measured by the temperature sensor 26b (or the temperature sensor 26c), and after the mixing process of homogenizing the lotion and water is performed, the water The texture sensor 35 measures electrical conductivity.

Here, using Fig. 16, the water supply of the outward tank in step S4, the water temperature in step S5, and the lotion state determination unit 117 in the measurement of electrical conductivity will be further described.

Figure 16 is a flow chart of the time for the dissolution of the lotion to be determined by the temperature and conductivity of the tap water.

In step S51, the temperature (water temperature) of the water containing lotion supplied to the water is measured by the temperature sensor 26b (or the temperature sensor 26c). In step S52, the lotion state determination unit 117 is YES Discriminate whether the type of lotion is liquid lotion or powder lotion (judgment of lotion state). Also, for this lotion state determination, Fig. 17 is used as described later. When the measured water temperature is higher than the threshold value t1 (Yes in step S53), proceed to step S54. When the measured water temperature is lower than the threshold value t1 (No in step S53), proceed to step S55. Here, because it has been determined by experiments that the melting condition of the lotion changes significantly around 10°C, in this embodiment, the variation is also taken into consideration and 13°C, which is slightly higher than 10°C, is set as the threshold. The value t1.

When it is determined in step S54 that it is a liquid lotion (Yes), the lotion melting time T0 is set (step S56). When it is not determined as a liquid lotion (No in step S54), the lotion melting time T1 is set (step S57). When it is judged as liquid lotion in step S55 (Yes), set to lotion melting time T2 (Step S58), when it is not judged as liquid lotion (No in step S55), set to lotion melting time T3 (Step S59).

Considering the water solubility of liquid lotion and powder lotion, it is better that lotion dissolving time T0 is longer than lotion dissolving time T1, or lotion dissolving time T3 is longer than lotion dissolving time T2. Also, if the water temperature is low, because the lotion is not easily dissolved in water, the lotion melting time T2 is longer than the lotion melting time T0, or the lotion melting time T3 is better than the lotion melting time T1.

And in step S1, when the setting of water washing treatment liquid input is ON, the lotion injected into the outer tank 22 becomes liquid lotion, so the rotation of the motor 23a in step S56 and step S58 can be suppressed The number (the action of the circulating pump 17) can reduce energy consumption.

Furthermore, in step S1, when the setting of the water washing treatment liquid input is ON, the determinations in step S54 and step S55 are Yes, and the lotion melting time is the lotion melting time T0, and When the lotion melting time is T2, but the powder lotion is mistakenly injected into the first input portion 31 due to an erroneous operation by the user, the determination in step S54 and step S55 is (No), and the lotion melting time is It can also be judged as the lotion melting time T1 and the lotion melting time T3.

According to this embodiment, the lotion melting time can be set according to the type of lotion and the water temperature, and the overall operation time can be shortened by shortening the lotion melting when the liquid is used for washing and the water temperature is high.

Next, the electrical conductivity measurement unit 115, the lotion state determination unit 117, and the foaming determination unit 118 in the lotion state determination in step S52 will be described using FIG. 17.

Figure 17 is a flow chart of determining the type of lotion based on the conductivity, estimating the ease of foaming from the result, and switching the washing time, the amount of water, and the number of motor rotations.

In the mixing process of step S520, the process control unit 112 controls the motor 23a through the motor drive circuit 121, and by rotating the water tank 21 and the rotating wing 21b, the outward tank 22 and the water tank 21 are supplied with water. The lotion and water can be homogenized by the flow of the lotion and water.

In step S520, in the case of powder lotion, it is difficult to uniformize the lotion and water. Therefore, it is necessary to control the rotation speed of the motor 23a at a high value. However, in the case of liquid lotion, the uniformity of the lotion and water is necessary. Since it is easy to change, the number of rotations of the motor 23a can be suppressed at a low level. Furthermore, in this embodiment, in step S520, the uniformizing means for the rotation of the water tank 21 and the rotating blade 21b is implemented, but the means for fixing the water tank 21 and rotating the rotating blade 21b and the circulating pump 17 are performed. It is also possible to implement the mixing process by means of homogenization.

Furthermore, in step S520, since the highest concentration lotion and water are stirred through the water washing process, the risk of foaming can be suppressed by suppressing the number of rotations of the motor 23a.

In this embodiment, in step S1, when the setting of the water washing treatment liquid input is ON, the lotion injected into the outer tank 22 becomes a liquid lotion, so the motor can be suppressed in step S520. The number of rotations of 23a is controlled.

In step S521, the conductivity measurement unit 115 measures the conductivity of the water that has been homogenized by the water quality sensor 35. Also, when measuring the conductivity, in order to improve the measurement accuracy, the water supplied from the water supply unit 20 to the outer tank 22, the circulation generated by the circulating pump 17, the rotation of the water tank 21 and the rotating wing 21b are stopped, and the outer tank 22 , And the water flow in the water tank 21 becomes slow, and it is better that the high-concentration cleaning liquid will not foam.

Therefore, in step S520, by suppressing the rotation speed of the motor 23a at a low level, the water flow generated in the outer tank 22 is weakened. Therefore, the time until the rotation of the motor 23a is stopped and the water flow in the outer tank 22 can be shortened. It is a measurement system that can improve the conductivity in a short time by reducing the time until it becomes suitable. Here, in this embodiment, the rotation speed of the water tank 21 generated from the predetermined water level before the lotion determination is 30 rpm or more and 70 rpm or less. As a result, foaming of the lotion liquid is suppressed, the accuracy of lotion discrimination is maintained, and the time until the water flow becomes suitable can be shortened.

Also, when the automatic lotion injection setting is off (OFF), powder lotion may be injected, but in this case, if the rotation speed of the sink 21 is not constant or higher, the powder lotion cannot be melted and the lotion discrimination is difficult. . On the other hand, when the automatic lotion injection setting is ON, the powder lotion will not be injected, so even if the rotation speed of the water tank 21 is low, it is possible to perform lotion discrimination. Therefore, in this embodiment, when the automatic lotion injection setting is turned on (ON), the rotation speed of the water tank 21 before the lotion determination can be reduced compared to when it is turned off (OFF). Specifically, when the automatic lotion injection setting is OFF, it is 80 rpm or less, preferably about 70 rpm, and when the automatic lotion injection setting is ON, it is 50 rpm or less, preferably about 35 rpm.

Fig. 20 is the result of measuring the unevenness of the conductivity caused by the number of rotations of the motor 23a in step S520. In the case of high-speed rotation, the maximum/minimum conductivity detection varies. By controlling the low-speed rotation, it is possible to suppress the maximum/minimum conductivity detection variation.

In step S522, when the electrical conductivity is smaller than the threshold value EC1 (Yes), proceed to step S524 to determine that it is a liquid lotion (concentrated), and switch the characteristics of the water quality sensor 35 according to this. When the conductivity is greater than or equal to the threshold value EC1 (No in step S522), and smaller than the threshold value EC2 (Yes in step S523), proceed to step S525, and determine that it is a liquid lotion (wash twice). When the conductivity is greater than or equal to the threshold value EC2 (No in step S523), proceed to step S526 to determine that it is a powder lotion, and change the washing time, the amount of water, and the number of motor rotations to switch the washing mode. For example, powder lotion has a tendency to foam easily, so compared with the case of liquid lotion (concentrated), the washing time is shortened, the amount of water is increased, the concentration of the lotion is reduced, and the number of rotations of the motor is reduced. It is not easy to foam, and by suppressing foaming, it is possible to prevent deterioration of cleaning performance and insufficient cleaning. Liquid lotion (concentrated) has a tendency to be less prone to foaming, so compared to the case of powder lotion, by extending the washing time, increasing the amount of water, reducing the concentration of the lotion, and increasing the number of rotations of the motor, you can reduce the risk of foaming. The low state improves the cleaning performance. The conductivity of liquid lotion tends to be in the middle of powder lotion and liquid lotion (concentrated), so by placing the washing method in the middle, it can be a suitable washing method. Therefore, because it is not foaming, but by detecting the type of lotion, it can be changed to the most suitable washing method, and there is no need to install a sensor for foaming detection. In addition, there is no need to distinguish whether the liquid lotion is a concentrated type, and the same cleaning method can be used regardless of the type of liquid lotion.

Although not shown in the figure, the foaming discriminating unit 118 is not limited to the type of lotion in step S524, step S525, and step S526. It is easy to foam by detecting water temperature, water hardness, and bath water usage conditions. The element of degree can improve the accuracy of the foaming discriminating section 118.

Concentrated liquid lotion that can be cleaned only once. Compared with liquid lotion that requires two cleansing operations, the conductivity is reduced. Therefore, the number of washings is changed from the result of the foaming determination section 118. It is also possible.

In step S6 of Fig. 15, the process control unit 112 only drives the motor 23a to rotate the water tank 21 and the rotor 21b by the lotion melting time determined in step S5, and generates the lotion by melting the lotion by the generated water flow. Highly concentrated lotion solution. In addition, the method of generating the high-concentration lotion solution is not limited to the method of rotating both the water tank 21 and the rotor 21b, and only the method of rotating the rotor 21b or using the reverse rotation of the circulating pump 17 may be used.

In step S7, the conductivity measuring part 115 measures the conductivity of the generated lotion solution by the water quality sensor 35, and the lotion state discriminating part 117 re-evaluates the discriminated lotion type and discriminates The concentration of the lotion actually put in. The generated lotion solution is to dissolve the lotion in a certain amount of water, so the change in the concentration of the lotion can be detected as the change in electrical conductivity. When the input amount of the lotion is large (the concentration of the lotion is high), compared with the case where the input amount of the lotion is small (the concentration of the lotion is low), the conductivity will become larger. Therefore, even if the foaming discriminating unit 118 discriminates the washing operation as one time, it is possible to change the washing operation to 2 times when the amount of the lotion injected is large. In addition, in this step S7, in order to improve the measurement accuracy of the electrical conductivity, once the water tank 21 and the rotor blade 21b rotating to melt the lotion are stopped, the rotation is restarted in the next step S8. Therefore, if this step S7 is skipped, the overall operation time can be further shortened.

In step S8, the process control unit 112 rotates the water tank 21 and the rotor blade 21b while feeding water from the water supply unit 20 until the water volume (water level) is less than the water volume in the subsequent washing process (S13 to S19) . In addition, since the water supply to the first input portion 31 is also performed at the same time, the water that is branched to the first water supply path 51 and the second water supply path 52 can also be washed at the same time for the conveyance path 53.

In step S9, the laundry is washed with a high-concentration lotion solution in a state of a smaller amount of water than in the subsequent washing process (S13 to S19). Hereinafter, in a state where the water level is lower than this washing process, while rotating the rotor blade 21b by the driving device 23, the high-concentration detergent solution is operated to penetrate the clothes, which is referred to as high-concentration washing. In addition, the high-concentration washing process in this embodiment is operated at a certain water level without water supply, but it may be operated while supplying water. However, the lotion melting operation in step S6 is not included in the high-concentration washing process if it is performed by another process (non-continuous) before reaching the predetermined water level.

In addition, in this embodiment, the liquid lotion and liquid lotion (concentrated) use a higher number of rotations than the powder lotion, and high-concentration washing is performed while rotating the motor (rotor blade 21b). net. Accordingly, in the case of high-concentration washing with easy foaming, foaming can be suppressed in the case of using a powder lotion, and in the case of using a liquid lotion, the cleaning power can be further improved.

Furthermore, in this embodiment, the operation time of the conventional high-concentration washing process of about 30 seconds is set to be about 2 minutes and 30 seconds. In this way, by lengthening the operation time of the high-concentration washing process, the grease can be effectively removed from food. On the other hand, it is also necessary to consider the need for "short time (shortened time in Japan)" to shorten the overall washing time. Here, it is better to lengthen the operation time of the high-concentration washing process. On the other hand, it is better to shorten the operation time of this washing process.

Figure 18 is a graph showing the results of testing the cleaning performance (cleaning ratio) when the ratio of the operating time of the high-concentration cleaning process to this cleaning process is changed. According to this figure 18, by setting the operation time of the high-density washing process (ratio of high-density washing) to 15% or more for the operation time of this washing course, it is possible to improve the performance compared with the conventional (high-density washing) Ratio = 4%) higher cleaning ratio. If the ratio of high-concentration washing is further set to 20% or more, it can be expected that the washing ratio will be greatly improved. In addition, if the ratio of this washing is too small, on the contrary, since the washing ratio is deteriorated, the ratio of high-concentration washing is preferably 35% or less.

In addition, in this embodiment, when the powder lotion is determined by the discrimination means (conductivity detection means for detecting the conductivity of the liquid in the outer tank 22) for discriminating the type of lotion injected, Compared with the case where the liquid lotion is judged, the rotation speed of the rotor blade 21b during the high-concentration washing process can be reduced. Therefore, even in the case of a powder lotion with easy foaming, the operation time of the high-concentration washing process can be lengthened while suppressing foaming, which can effectively remove grease stains.

Next, the case of a washing machine not provided with the circulation pump 17 will be described. When there is no circulation pump 17, especially when the water level is low, it is difficult to spread a high-concentration lotion solution from above to the laundry laundry. Therefore, a difference in water content occurs between the upper and lower parts of the water-washed laundry, and the action of the water-washed laundry is slowed down, which may cause uneven washing. Here, in this embodiment, in the center and the end (near the inner wall) of the sink 21, by spreading the washing water in advance, the water laundry stacked in the center and the water laundry attached to the end The action is good, even if the water level is low, the difference in the water content of the laundry can be suppressed. For the specific structure, as described below.

FIG. 19 shows the state of the pouring washing water falling from the water injection hose 51a into the water tank 21. As shown in FIG. As shown in the figure, the washing water is distributed substantially linearly toward the center part (Wa), the end part (Wb), and the middle part (Wc) between the end part and the center part of the water tank 21. This makes it possible to spray water (sprinkle water) on the entire washing tank from the water supply stage, not only the ends, but also to the center, so that the entire clothes can be easily hydrated, and the cloth action during washing can be improved and uneven washing can be suppressed. .

In step S10, first, the laundry weight calculation unit 114 calculates the weight of the laundry in a state including water. In addition, the cloth quality (water absorption) of the clothes is determined from the weight of the clothes in the state not containing the water calculated in step S1 and the weight of the clothes in the state including the water calculated in step S10. The fabric quality of the clothes to be judged is controlled by the following process.

In step S11, the water temperature before the water washing process is obtained. When the water temperature is high, the chemical effect of the lotion will be improved, and the washing power can be improved, so the washing time can be shortened. By measuring the water temperature before the washing process, for example, the water temperature can be accurately detected when washing with hot water from a bath, and the washing time can be changed.

When the measured water temperature is high and the water hardness is low, the washing time can be shortened by skipping step S18 and step S19.

In this way, the ease of foaming during the washing process is measured by using the water quality sensor 35 to measure the conductivity of the washing liquid, and controlled by the foaming discrimination unit 118 to control (shorten or extend) the washing time. The detergent amount/washing time determining unit 116 is a table of contents that memorizes in advance the washing time (shortened or extended time) determined according to the degree of soiling. In addition, a complex threshold value may be set based on the cloth amount calculated in step S1.

When this washing is completed, the unbalanced state of the clothes is monitored in step S20, and it is determined whether or not it has moved to dehydration.

In step S21, the process control unit 112 opens the drain valve 65 to drain the washing water in the outer tank 22. After the draining is completed, in step S22, the process control unit 112 spins the water tank 21 to spin water (wash water) contained in the laundry.

The process control unit 112 closes the drain valve 65, opens the valve of the water supply unit 20, and supplies washing water to the water tank 21. And, the water tank 21 is rotated, and washing water is spread to the clothes in the water tank 21 (step S23).

The process control unit 112 rotates the water tank 21, closes the valve of the water supply unit 20, and spins the washing water from the laundry (step S24) The process control unit 112 rotates the water tank 21, opens the valve of the water supply unit 20, and distributes washing water to the clothes in the water tank 21 (step S25).

The process control unit 112 closes the valve of the water supply unit 20, stops the water tank 21, opens the drain valve 65, and drains the washing water in the outer tank 22 (step S26). After the drainage is completed, the process control unit 112 spins the water tank 21 to spin-dry the water (washing water) contained in the clothes (step S27).

The execution of the spin washing in step S23 and step S25 is determined by the foaming discriminating unit 118, and when the number of washing times is determined to be one, step S23 to step S27 are skipped by sending a signal to the process control unit 112 Command, it becomes possible to perform one cleaning operation.

When dehydration is normally terminated, the outer tank 22 is in an anhydrous state, and the water quality sensor 35 is operated to measure the conductivity of anhydrous water (step S28). The conductivity measured here is stored in the conductivity measurement unit 115 as an initial value, and is used for fault diagnosis of the water quality sensor 35 and correction of changes over the years caused by dirt adhesion to the electrode unit.

The process control unit 112 closes the drain valve 65, opens the valve of the water supply unit 20, and supplies washing water to the outer tank 22 until the water level at which the water hardness is detected (step S29). The conductivity measuring unit 115 operates the water quality sensor 35 and the temperature sensor 26b (or the temperature sensor 26c), measures the water temperature and conductivity of the washing water, and calculates the water hardness (step S30). The water temperature and water hardness measured here are memorized in the detergent amount/washing time determination unit 116 and used for the next determination of the detergent amount and washing time.

And in step S1, as long as the setting of the washing treatment liquid input is ON, the water temperature and conductivity of the washing water in step S30 are measured to calculate the hardness of the water, and it is determined by the detergent amount/washing time determination unit 116 The subsequent treatment dose is controlled by the transfer pump 46 by the transfer pump drive circuit 126, and the water washing treatment liquid is supplied to the first input portion 31 through the transfer path 53.

The process control unit 112 feeds water until the water level is set (step S31), and stirs the clothes while rotating the rotor blade 21b (or the water tank 21) while the washing water is retained in the outer tank 22, and turns on the water supply unit 20 The valve puts the post-treatment agent into the water tank 21 (step S32). In addition, since the water supply to the first input unit 31 is also performed at the same time, the first water supply path 51 and the second water supply path 52 are branched, and the washing treatment liquid remaining in the transport path 53 can be transported to the first input unit 31.

In this step S33 to step S35 (washing 2 process), by operating the water quality sensor 35 to detect the change in conductivity of the washing water, the washing degree of the laundry can be detected. By the way, the water quality sensor 35 in this embodiment is set at the lower part (bottom) of the outer tank 22, so during the cleaning process, when the water quality sensor 35 is submerged, the water quality sensor 35 can be measured. Conductivity.

In this way, by using the water quality sensor 35 to measure the conductivity of the cleaning water during the cleaning process, the cleaning time can be controlled (shortened or extended). A table of contents of the cleaning time (shortened or extended time) determined from the change in the conductivity of the cleaning water is memorized in advance. In addition, the amount of change in the electrical conductivity of the washing water may be judged by comparing it with the electrical conductivity of the tap water measured in step S30.

In addition, the amount of change in the conductivity of the washing water can be used to increase or decrease the number of washings in addition to shortening/prolonging the washing time. Therefore, even if it is determined by the lotion state determination unit 117 that the washing operation is one time, a concentrated type liquid lotion is possible, and the foaming determination unit 118 determines that the washing operation is one time, if it is determined as When cleaning is insufficient, additional cleaning operation can be implemented.

In addition, the time point at which the water quality sensor 35 is activated during the cleaning process is not limited to the time of step S33 to step S35. In step S23 and step S25, operation S23 and step S25 are activated to control the cleaning time (shorten or Extension) is also possible.

In step S23 or step S25, the washing time may be controlled (shortened or extended) based on the cloth quality of the clothes determined in step S10.

If the resident washing ends, the unbalanced state of the clothes is monitored, and it is judged whether or not it has moved to the final spin-drying (step S36).

The process control unit 112 opens the drain valve 65 to drain the washing water in the outer tank 22 (step S37). In step S37, in order to stabilize the startup during dehydration, there is a case where it moves to step S38 (dehydration process) with a certain amount of washing water remaining.

The process control unit 112 spins the water tank 21 at a high speed to spin water contained in the clothes (step S38). In this step S38 (dehydration process), by measuring the water dehydrated from the laundry using the water quality sensor 35, the amount of water contained in the laundry can be discriminated. During the spin-drying process, the water tank 21 rotates to separate the water contained in the laundry laundry from the laundry, and is discharged from the through hole 21aa of the water tank 21 toward the inner surface of the peripheral wall 22e of the outer tank 22. The water discharged toward the peripheral wall portion 22e flows down the inner surface of the peripheral wall portion 22e by the action of gravity, and flows into the groove portion of the water quality sensor 35. Thus, the water quality sensor 35 can detect the electrical conductivity of the water during dehydration.

That is, in the water quality sensor 35 during dehydration, when water flows into the groove of the water quality sensor 35, the detection value (conductivity) changes according to the amount of water passing through. For example, when the water-washed laundry is a person with high water absorption such as a bath towel, the amount of water discharged increases, and the detection value (conductivity) increases. On the other hand, for example, when the water-washed laundry is a person with low water absorption such as a white shirt, the amount of discharged water decreases, and the detection value (conductivity) decreases.

In this way, by using the water quality sensor 35 to measure the electrical conductivity of the water dehydrated from the laundry during the dehydration process, the dehydration time can be controlled (shortened or extended). The detergent amount/washing time determining unit 116 stores a table of contents for determining the dehydration time (shortening or extending the time) in advance. In addition, a complex threshold value may be set based on the cloth amount calculated in step S1.

In addition, the time point at which the water quality sensor 35 is activated during the dehydration process is not limited to step S38. It operates during steps S22, S24, and S27 of other dehydration processes, and the dehydration time can be controlled (shortened or extended). can.

＜Main features of control＞ As explained above, in the washer-dryer 1 of this embodiment, in step S1, when the washing treatment liquid input setting is ON, the lotion injected into the outer tank 22 becomes liquid lotion. , It becomes possible to control the rotation speed of the motor 23a in step S520. As a result, since the water flow generated in the outer tank 22 is weakened, the time until the rotation of the motor 23a is stopped in step S521 and the time until the water flow in the outer tank 22 becomes appropriate can be shortened, which can be shortened. Improve the conductivity measurement system.

And by measuring the conductivity of the water containing the lotion, it can be determined that the type of lotion is liquid lotion or powder lotion (refer to S522, S523), when it is determined that it is not a liquid lotion (S54 is No, or S55 is No), set the melting time of the lotion to be longer than that of the liquid lotion. As a result, it has a longer melting action than liquid lotion lotion, can prevent the melting residue of powder lotion, and can spread high-concentration lotion solution everywhere during the pre-washing process, which can improve the cleaning performance.

And when it is judged that it is a liquid lotion (S54 is Yes, or S55 is Yes), set the lotion melting time to be shortened, shorten the time of the lotion melting action, and set the circulation pump 17 (or the water tank 21, Or if the driving time of the rotor 21b) is shortened, the number of rotations can be suppressed and energy consumption can be reduced.

Moreover, in this embodiment, by measuring the temperature of the water containing the lotion, the time for the action of melting the lotion can be changed according to the water temperature. (Refer to S56, S57, S58, S59). That is, for the lotion melting time when the water temperature is higher than the threshold value t1, the lotion melts easily, if it is a liquid lotion, set it to the lotion melting time T0 (S56), if it is a powder lotion, set it to the lotion melting time Time T1 (S57). If the water temperature is below the threshold value t1, the lotion will not easily melt. If it is a liquid lotion, set it to the lotion melting time T2 (S58), if it is a powder lotion, set it to the lotion melting time T3 (S59) . The melting time of the lotion is set to be longer than that of liquid lotion (T1>T0, T3>T2). When the water temperature is high, set it to be shorter (T0<T2, T1<T3). The time for the lotion melting action is shortened, and the driving time of the circulation pump 17 (or the washing and dewatering tank 8, or the rotary wing 8a) is shortened, so that the number of rotations can be suppressed and energy consumption can be reduced.

And when the conductivity of the water containing the lotion is lower than the threshold value EC1 (for example, when the cleaning operation is one time or a concentrated type of liquid lotion) (S522 is Yes), set the number of cleaning operations to 1. When the conductivity is greater than or equal to the threshold value EC1 (for example, when the cleaning operation is a liquid lotion for 2 times) (S522 is No), set the number of cleaning operations to 2 (refer to S525, S526) . In this way, the state of the lotion (type of lotion) can be determined based on the electrical conductivity, and the appropriate number of washing operations can be set, so the washing operation time can be shortened, and the action time of the motor 23a during the washing process can be shortened , Suppress the number of rotations, reduce energy consumption, and reduce the amount of water used.

Here, the conductivity measurement of the water containing the lotion is performed before the lotion melting action (S6), and it is better to set the time of the lotion melting action according to the type of lotion. In order to dissolve the lotion (S6), the amount of water supplied is a certain amount. Compared with the amount of water in this washing process (S13 to S19), the concentration of the lotion becomes higher because it is less, and the type of lotion (concentrated) Types of liquid lotion, liquid lotion, powder lotion) the degree of conductivity difference. Based on the result of this judgment, the lotion melting action (S6) is executed, and then again, by measuring the conductivity (S7), it is possible to re-evaluate whether the judgment result of the lotion type is wrong, and because of the amount of lotion put in (Concentration of lotion) can also be used as a measurement of the difference in conductivity, so the discriminability of the state of lotion can be optimized.

In addition, the lotion state determination unit 117 corrects the threshold value EC1 and the threshold value EC2 of the conductivity based on the conductivity (hardness) measured in step S30 during the previous washing operation and the water temperature measured in step S5. That is, when the water temperature is high and when the conductivity (hardness) of the water is high, the threshold value EC1 and the threshold value EC2 are set to be increased.

In this way, because the threshold value of the conductivity can be corrected by the water temperature and the conductivity (hardness) of the water, the state of the lotion can be best judged.

In this embodiment, the description has been given of changing the number of washing operations based on the conductivity of the washing liquid. However, for example, a configuration in which the amount of water used in the washing operation is changed may be used. Specifically, the higher the electrical conductivity, the more the amount of water used in the washing operation can be controlled. That is, when there is a lot of lotion added (the concentration of lotion is high), the lotion may foam excessively during the washing operation, but by increasing the amount of water used, the foaming of the lotion can be reduced . In addition, a configuration in which the operation time and the amount of water used in the pre-washing process and the current washing process are changed according to the conductivity of the washing liquid may also be used.

In the above, the washing machine of this embodiment has been described using a vertical type washer-dryer in which the rotation axis of the washing and dehydration tank is substantially vertical, but it is not limited to this. The rotation axis of the rotating drum (washing and dehydration tank) is A drum-type washer-dryer in a substantially horizontal direction may be used, as well as a vertical-type washing machine or drum-type washing machine that does not have a drying function.

In addition, the water quality sensor 35 (conductivity detection means) is not limited to the configuration of this embodiment, and it may be configured to detect the conductivity of the lotion solution. For example, although it has been described that the capacitance of the capacitor of the oscillation circuit 39 is changed to switch the characteristics, it is not a capacitor but a resistor or a coil.

＜Main features of washing machine＞ In this embodiment, since the conventional washing machine has the following problems, the washing machine 1 that can solve the problems is deliberately provided.

(1) The conventional washing machine is equipped with a hose connected to a water tank (washing and dehydration tank) in the manual input part and the washing treatment liquid input device. That is, the conventional washing machine is provided with: a first system of hoses connecting a manual input unit and a water tank (washing and dehydrating tank), and a second system connecting a washing treatment liquid input device and the water tank (washing and dehydrating tank) System hoses, plural hoses. Since such a conventional washing machine has a large number of hoses, there is a problem that the risk of water leakage caused by the falling of the hose and the rupture of the hose is relatively high.

In this regard, as shown in FIG. 6, the washing machine 1 of this embodiment transports the washing treatment liquid contained in the tank 42 from the tank 42 to the first input portion 31 through the transfer path 53 and passes through the input path 54 It is thrown into the water tank 21 from the 1st throw-in part 31.

In the washing machine 1 of this embodiment, the hose connecting the washing treatment liquid input device 30 and the water tank 21 can be eliminated. Therefore, compared with the conventional washing machine, the washing machine 1 of this embodiment can reduce the risk of water leakage caused by the removal of the hose and the rupture of the hose. As a result, in the washing machine 1 of this embodiment, the risk of water leakage can be reduced to 1/2 of that of the conventional washing machine, and the reliability of this portion can be improved.

(2) In the conventional washing machine, when the detergent is injected, it is necessary to separately supply water to both the manual injection part and the washing treatment liquid injection device, so there is a problem that a relatively large amount of water is used when the detergent is injected.

In this regard, as shown in FIG. 6, in the washing machine 1 of the present embodiment, since the water supplied to the washing treatment liquid input device 30 is supplied to the first input portion 31, it is possible to reduce the amount of water used when the lotion is input. As a result, the washing machine 1 of this embodiment can reduce the amount of water used when the detergent is put in, for example, to about 1/2 of that of the conventional washing machine, and the use cost of this part can be reduced.

(3) In the conventional washing machine, the water supply means is arranged at the upper rear part of the housing, and the manual input part is arranged at the front. In addition, between the water supply means and the manual input unit, and at a place on the side of the water tank (washing and dehydration tank), the tank of the washing treatment liquid input device and the input unit (automatic input unit) are arranged. Therefore, in the conventional washing machine, the input unit (automatic input unit) of the washing treatment liquid input device is arranged at a place away from the position where the user stands. Therefore, in the conventional washing machine, when the user puts the washing treatment liquid into the automatic charging unit, it has a problem that it is difficult to put the washing treatment liquid and the usability is poor.

In this regard, as shown in FIG. 5, the washing machine 1 of the present embodiment is provided with a second input unit 32 (automatic input unit) at a place close to the position where the user stands. Therefore, the washing machine 1 of the present embodiment can easily put the washing treatment liquid into the second input section 32 (automatic input section). The washing machine 1 of this embodiment can improve the ease of use.

(4) In the conventional washing machine, the automatic injection part of the washing treatment liquid injection device is arranged behind the manual injection part. Therefore, in the conventional washing machine, when the user holds the replenishing container of the water washing treatment liquid and throws the water washing treatment liquid into the automatic feeding part, the frame body will collide with the body part (or the bottom part) of the replenishing container. Therefore, in the conventional washing machine, the discharge port of the replenishing container is arranged at a relatively high position above the automatic input section, and it is necessary to put the washing treatment liquid into the automatic input section in this state. Since such a conventional washing machine causes the washing treatment liquid to be injected into the automatic input part from a relatively high position, there is a problem that the washing treatment liquid cannot be poured into the automatic injection part intelligently and overflows.

In this regard, as shown in FIG. 11B, in the washing machine 1 of the present embodiment, the second input section 32 (automatic input section) is arranged in front of the first input section 31 (manual input section). Therefore, in the washing machine 1 of this embodiment, when the user holds the replenishing container 91 of the water washing treatment liquid and puts the water washing treatment liquid into the second input part 32 (automatic input part), the frame body 11 does not interact with the carcass of the replenishing container 91. The part (or the bottom) conflicts. Therefore, in the washing machine 1 of the present embodiment, the discharge port of the replenishing container 91 can be directed to the second input portion 32 to input the washing treatment liquid into the second input portion 32. In the washing machine 1 of this embodiment, since the washing treatment liquid is injected into the second input section 32 from a relatively low position, the washing treatment liquid can be wisely injected into the second input section 32 without overflowing. As a result, the washing machine 1 of the present embodiment can prevent the area around the second input portion 32 from being soiled by the washing treatment liquid.

(5) The conventional washing machine has a problem that when the user throws the washing treatment liquid into the automatic input part, the washing treatment liquid overflows the operation panel, which causes the erroneous operation of the buttons and the touch panel.

In this regard, the washing machine 1 of the present embodiment, as described in the aforementioned item (4), can be wisely injected into the second input portion 32 (automatic input portion) without overflowing the washing treatment liquid. Therefore, the washing machine 1 of this embodiment can suppress the erroneous operation of the buttons and the touch panel caused by the overflow of the washing treatment liquid on the operation panel 14 (refer to FIG. 1).

(6) In the automatic injection part of the water washing treatment liquid injection device, a larger amount of water washing treatment liquid is injected than the manual injection part. Even so, in the conventional washing machine, the automatic throw-in part is provided behind the manual throw-in part. Therefore, the conventional washing machine (especially, the vertical washing machine) has a problem that the usability of the washing treatment liquid input device is poor.

In this regard, as shown in Fig. 5, in the washing machine 1 of the present embodiment, the second input section 32 (automatic input section) into which a relatively large amount of washing treatment liquid is input is provided at a higher level than the first input section 31 (manual input section). Department) more forward. Therefore, the washing machine 1 of this embodiment can improve the usability of the washing treatment liquid input device 30.

(7) When the conventional washing machine has a drying function, for example, a drying unit is arranged on the upper rear part of the housing. The conventional washing machine with this configuration has a relatively close distance between the tank of the washing treatment liquid input device and the drying unit, so the washing treatment liquid contained in the tank is gelled by the heat from the drying unit. Subject.

In this regard, as shown in FIG. 4, in the washing machine 1 of the present embodiment, a drying unit 71 is arranged on the upper rear part of the housing 11, and a washing treatment liquid input device 30 is arranged on the upper front part of the housing 11. That is, in the washing machine 1 of the present embodiment, the washing treatment liquid input device 30 is arranged at the place farthest from the drying unit 71 in the upper part of the housing 11. Therefore, the washing machine 1 of the present embodiment can suppress the gelation of the washing treatment liquid contained in the tub 42 due to the heat from the drying unit 71.

(8) In general washing machines, it is desirable to reduce the horizontal width. However, in the conventional washing machine, since the washing treatment liquid input device is mounted on the side of the sink, it is necessary to reduce the size of the laundry input portion (the opening of the sink). Thereby, the conventional washing machine (especially, the vertical washing machine) has a problem that the ease of putting clothes in is reduced.

In this regard, as shown in FIG. 5, in the washing machine 1 of the present embodiment, the washing treatment liquid input device 30 is mounted in a place in front of the water tank 21. Therefore, it is not necessary to reduce the size of the clothing input portion (the opening portion of the water tank 21). Therefore, the washing machine 1 of this embodiment can improve the ease of putting clothes in.

(9) In the conventional washing machine, a tank with a washing treatment liquid input device extending in the front and rear direction is placed on the side of the water tank (washing and dehydration tank), and the tank cannot be removed. Therefore, the conventional washing machine has a problem that it is impossible to wash the tub or the like.

In this regard, as shown in Figs. 7 to 9, the washing machine 1 of this embodiment can remove the tank 42 of the washing treatment liquid input device 30, so that the tank 42 and the like can be washed.

(10) The conventional washing machine is provided with a cover that seals the automatic input portion. This cover has a structure that can be opened to either the left or the right. Such a conventional washing machine has a problem that it is difficult to open the cover when the direction in which the cover is opened is opposite to the user's dominant hand.

Regarding this, as shown in Figs. 7 and 8, the washing machine 1 of the present embodiment has an inlet cover 43a (first cover) configured to be openable and closable from the front to the back in the vertical direction. Therefore, in the washing machine 1 of this embodiment, the input port cover 43a (first cover) can be opened regardless of the dominant hand. Thus, the washing machine 1 of the present embodiment can easily input (replenish) the water washing treatment liquid into the second input portion 32 (automatic input portion) regardless of the dominant hand.

(11) In the conventional washing machine, when the user forgets to close the cover sealing the automatic input unit and performs the water washing, there is a problem that the washing treatment liquid leaks from the tank of the washing treatment liquid input device.

In this regard, as shown in Fig. 12, the washing machine 1 of the present embodiment assumes that the user forgets to lock the input port cover 43a (first cover) and washes it with water. The tank storage cover 15 ( The second cover) is locked to automatically lock the input port cover 43a. Therefore, in the washing machine 1 of this embodiment, even in this case, the water washing treatment liquid can be prevented from leaking from the tank 42 of the water washing treatment liquid input device 30.

(12) In the conventional washing machine, when the washing treatment liquid contained in the tank of the washing treatment liquid input device is sent to the sink by air pressure, there may be parts in the pipe path through which the washing treatment liquid passes. . The conventional washing machine has a problem that it is difficult to clean a part where water does not pass.

In this regard, as shown in Fig. 6, in the washing machine 1 of this embodiment, although the washing treatment liquid contained in the tank 42 of the washing treatment liquid input device 30 is sent out to the conveying path 53, the water is conveyed through this Any location on path 53. Therefore, in the washing machine 1 of this embodiment, the conveyance path 53 can be cleaned reliably.

As described above, according to the washing machine 1 of the present embodiment, it is easy to put the washing treatment liquid into the washing machine, and the usability can be improved.

The present invention is not limited to the foregoing embodiments, and may include various modifications. For example, the foregoing embodiments are described in detail in order to facilitate the understanding of the present invention, and are not limited to those that have all the described components. In addition, a part of the configuration of the embodiment may be replaced with another configuration, and another configuration may be added to the configuration of the embodiment. In addition, for a part of each configuration, other configurations can be added, deleted, or replaced.

For example, the tank 42 preferably has a claw-shaped engaging means or the like that can be strongly engaged with the shell 41.

Also, for example, in the aforementioned embodiment, the vibration damping member 45 is provided in the case 41. However, the vibration damping member 45 may be provided on either or both of the tank 42 and the shell 41.

In addition, for example, the input port cover 43a (first cover) may have a structure that opens and closes slidingly from the front to the back.
