The air duct 73 is arranged between the fan 72 and the blowing nozzle 74, and a drying unit 71 (heater) is arranged in the middle. The air duct 73 is connected to the blowing nozzle 74 by a bellows 73a. The blowing nozzle 74 blows the drying air blown out by the fan 72 and heated by the drying unit 71 into the outer tank 22. The drying duct 81 is arranged between the outer tank 22 and the fan 72. The drying duct 81 is connected to the concave portion 22c of the outer tank 22 by a bellows 81a and has a dehumidifying mechanism inside.

In this configuration, the washing machine 1 is supplied with water from the water supply unit 20 (water supply means) to the outer tank 22 during the water washing process and during the washing process, and the water tank 21 (washing and dewatering tank) is immersed in water. The washing machine 1 is, for example, in a drying process, the fan 72 is rotated to send air toward the air duct 73, and the drying unit 71 heats the air to obtain dry air, and the dry air passes through the outer tank 22 and the water tank 21. Thus, the washing machine 1 dries the object to be washed (cloth) contained in the water tank 21. In addition, in the washing machine 1, the air passing through the outer tub 22 and the water tub 21 is sent from the drying duct 81 to the air duct 73 by the fan 72, and the same operation is repeated.

As shown in FIG. 4, the washing machine 1 includes a water injection hose 51a, a feed hose 54a, and a washing hose 61a.

In addition, the washing machine 1 is provided with a casing 41 accommodating the tub 42 in the upper front part of the housing 11. The tank 42 is configured to be removable and attachable to the case 41 by moving in the vertical direction. In addition, the case 41 has a structure that can automatically put lotion and softener into the water tank 21, and it is preferable that at least two tanks 42 for lotion and softener can be accommodated.

As shown in FIG. 5, the case 41 has a rectangular shape in a front view and a rectangular shape in a side view. Therefore, the shell 41 has a substantially rectangular parallelepiped shape whose overall shape is thin in the depth direction. The case 41 is arranged to extend in the vertical direction along the inner wall surface of the front operation panel 16 (refer to FIG. 4 ). Below the casing 41, a transfer pump 46 is arranged.

Either one or both of the case 41 and the tub 42 preferably have a vibration damping member 45 which functions as a suppression means for suppressing the vibration of the water-washing liquid contained in the tub 42 between the water tank 21 and the (See Figure 4) Better. Thereby, the washing machine 1 can suppress the vibrations propagated from the drive device 23 and the like, causing the water treatment liquid stored in the tub 42 to swing and splash.

In addition, the case 41 is attached to the upper front portion of the housing 11 and is held between the inner wall surface of the front operation panel 16 and the housing 11. Therefore, even if it is assumed that there is no vibration damping member 45 (refer to FIG. 4 ), the washing machine 1 can suppress the swing of the water washing treatment liquid stored in the tub 42. However, in the washing machine 1, by providing the vibration damping member 45 (refer to FIG. 4 ), it is possible to further efficiently suppress the swing of the washing liquid treated in the tub 42.

In this configuration, the second input portion 32 and the tank 42 of the water washing treatment liquid input device 30 are arranged further forward than the center of the water tank 21 (for example, a portion connected by the rotating shaft 23c (refer to FIG. 4)). . In addition, the drying unit 71 (heater) is disposed behind the center of the water tank 21 separately from the second input portion 32 and the tank 42.

The upper part of the side surface of the outer tank 22 is provided with an acceleration sensor 27 that detects the acceleration of vibration caused by the vibration of the outer tank 22. In addition, the signals detected by the water level sensor 28, the temperature sensors 26a, 26b, 26c, and the acceleration sensor 27 are sent to the control device 100.

The water quality sensor 35 (conductivity detection means) detects tap water before washing and conductivity of the washing liquid during washing (washing, washing, dehydration), and is arranged on the outer periphery of the bottom wall portion 22d of the outer tank 22 Margin. The water quality sensor 35 includes a base made of synthetic resin and a pair of electrodes 36A and 36B. The groove of the water quality sensor 35 extends in the radial direction S (normal direction) of the outer groove 22 To configure.

The surface passing from the peripheral wall portion 22e of the outer groove 22 through the groove portion of the water quality sensor 35 to the bottom wall portion 22d of the outer groove 22 is an almost continuous surface. For example, during the dehydration process during the washing operation, a part of the washing water discharged from the through hole 21aa of the water tank 21 toward the outer tank 22 flows down along the peripheral wall portion 22e of the outer tank 22 and flows through the water quality sensor 35 The bottom wall portion 22d of the groove portion and the outer groove 22 of FIG.

<Configuration of piping path> Hereinafter, the configuration of the piping path of the washing machine 1 will be described with reference to FIG. 6. FIG. 6 is a schematic diagram showing the piping path of the washing machine 1.

As shown in FIG. 6, the washing machine 1 is equipped with a first water supply path 51, a second water supply path 52, a transport path 53, and an input path as a piping path used for washing an object (cloth) to be washed 54.

The first water supply path 51 connects the water supply unit 20 and the first input unit 31, and supplies water from the water supply unit 20 to the first input unit 31.

The second water supply path 52 connects the middle of the first water supply path 51 and the conveyance path 53, and supplies water from the water supply unit 20 to the conveyance path 53 through the first water supply path 51.

The main water supply path 55 connects the water supply unit 20 and the water tank 21 (outer tank 22), and direct water is supplied from the water supply unit 20 toward the water tank 21.

The conveyance path 53 connects the tub 42 and the first input portion 31, and conveys the water treatment liquid discharged from the tub 42 through the transport pump 46.

The input path 54 connects the first input portion 31 and the water tank 21 (outer tank 22 ), and the washing treatment liquid and water are input from the first input portion 31 toward the water tank 21.

A switching valve 64 is arranged at the connection between the second water supply path 52 and the conveyance path 53. The switching valve 64 is a switching means for switching the flow of fluid. The switching valve 64 (switching means) selectively switches either one of the direction in which the water washing treatment liquid flows from the tank 42 toward the transport path 53 and the direction in which the water flows from the second water supply path 52 toward the transport path 53.

And on the path of the conveyance path 53, the conveyance pump 46 and the check valves 47a and 47b which prevent backflow of fluid are arranged. The check valves 47a and 47b are arranged on the upstream side (the tank 42 side) and the downstream side (the first input portion 31 side) of the transfer pump 46, respectively.

In addition, the washing machine 1 includes a first washing path 61, a second washing path 62, and a discharge path 63 as a piping path used for washing the water tank 21, the outer tank 22, the case 41, and the like.

The first washing path 61 connects the water supply unit 20 and the first input unit 31, and supplies water for washing from the water supply unit 20 to the first input unit 31.

The second washing path 62 connects the casing 41 to the middle of the first washing path 61, and supplies washing water from the water supply unit 20 to the casing 41 through the first washing path 61.

The discharge path 63 connects the shell 41 and the drain port 66 to drain water from the shell 41.

The discharge path 63 is composed of a drain pipe 63a connecting the shell 41 and the drying duct 81, a drain pipe 63b connecting the drying duct 81 and the outer tank 22, and a drain valve 65 and a drain port 66 provided in the outer tank 22 The drain pipe 63c is connected.

A drain valve 65 is provided in the outer tank 22. In the washing machine 1, the drain valve 65 is opened, and the washing treatment liquid and water are discharged to the outside from the drain port 66 through the drain pipe 63c.

When such a washing machine 1 is automatically charged (that is, when the washing liquid treatment liquid is injected into the water tank 21 by the washing liquid treatment liquid input device 30), the washing liquid stored in the tub 42 passes through the transport path 53 The tank 42 is transported toward the first input section 31. In addition, the washing machine 1 can introduce the transported water washing treatment liquid into the water tank 21 from the first input unit 31 through the input path 54. Therefore, the washing machine 1 passes through the first injection part 31 when the manual washing and automatic injection are performed regardless of the water washing treatment liquid. Therefore, by passing water through the first injection part 31, the amount of water used when the detergent is injected can be reduced.

The washing machine 1 conveys the water washing treatment liquid contained in the tub 42 from the tub 42 to the first input portion 31 through the transport path 53. At this time, although a part of the water washing treatment liquid remains in the transport path 53, the water washing water remaining in the transport path 53 can be transported toward the first input part 31 by the water supplied from the second water supply path 52.

In addition, the second water supply path 52 of the washing machine 1 is connected to the middle of the first water supply path 51. Therefore, the washing machine 1 assumes that the conveying path 53 is clogged and unexpected pressure is applied to the conveying path 53. The pressure applied to the conveying path 53 may be directed outward through the first water supply path 51 (water tank 21) Side) release. Therefore, the washing machine 1 can reduce the pressure applied to the conveyance path 53 assuming that this phenomenon occurs. Thereby, the washing machine 1 can maintain the performance of the conveyance path 53 relatively long.

In addition, the washing machine 1 can wash the first input part 31 by flowing washing water from the water supply unit 20 toward the first input part 31 along the first cleaning path 61.

In addition, the washing machine 1 can wash the casing 41 by flowing washing water along the second washing path 62 from the water supply unit 20 toward the casing 41. In particular, if the nozzle 41a (refer to FIG. 10) fitted to the lower portion of the tank 42 is provided at the bottom of the casing 41, the nozzle 41a (refer to FIG. 10) can be washed.

In addition, the washing machine 1 can discharge the washing water supplied to the first washing path 61 toward the water tank 21 along the input path 54, and can also follow the washing water supplied to the second washing path 62. The drain 63a (via the drying duct 81) is discharged toward the water tank 21. Therefore, the washing machine 1 can wash the water tank 21 and the outer tank 22.

<Structure of tank> Hereinafter, the configuration of the tank 42 will be described with reference to FIGS. 7 to 10. 7 to 9 are perspective views each showing the external configuration of the tank 42. FIG. 10 is a cross-sectional view showing the internal structure of the tank 42.

As shown in FIGS. 7 to 9, the tank 42 has an upper cover 43 and a handle 44. Fig. 7 shows a state where the inlet cap 43a is closed. Fig. 8 shows a state in which the input port cover 43a is opened. Fig. 9 shows a state where the upper cover 43 is removed.

The upper cover 43 is a cover member that covers the upper surface of the tank 42.

The handle 44 is a member held by the user.

The second input portion 32 is provided on the upper surface cover 43 and sealed by the input port cover 43a. The inlet cover 43a is configured to be openable and closable in the longitudinal direction from front to back.

The upper surface of the upper surface cover 43 is an inclined surface that slopes downward from the rear toward the front. Such a top cover 43 can make the length of the inlet cover 43a longer in the opening/closing direction compared with the case where the top surface is assumed to form a horizontal plane. In addition, in such a top cover 43, when the input port cover 43a is opened, the input port cover 43a can be protruded greatly upward. Therefore, such a top cover 43 can improve the operability of the opening and closing operation of the inlet port cover 43a, and can easily open and close the inlet port cover 43a.

As described above, the tank 42 is configured to be detachable and attachable to the case 41 (refer to FIG. 5) by moving up and down. The tub 42 can be easily removed from the housing 41 by the user pulling the handle 44 upward. As shown in FIG. 9, the upper cover 43 can be removed from the tank 42.

The user can remove the tank 42 from the shell 41 and the upper cover 43 from the tank 42, so the shell 41 and the upper cover 43 can be easily washed by hand.

As shown in FIG. 10, a discharge port 49 (through hole) is provided in the lower portion of the tank 42. The discharge port 49 has a structure to fit into the nozzle 41a provided in the case 41. Thereby, the tub 42 can surely send the washing liquid to the conveying path 53 (refer to FIG. 6). Inside the tub 42, a bottom portion inclined downward toward the discharge port 49 is provided. In addition, the discharge port 49 is provided with a fine-mesh mesh tank barrel mesh 48. Thus, the washing machine 1 assumes that even if a foreign matter is mixed into the inside of the tub 42, the foreign matter can be prevented from entering the conveyance path 53 (refer to FIG. 6 ).

<Injection operation of the washing solution for the second injection unit (automatic injection unit)> As described below, the washing machine 1 of the present embodiment has a structure in which it is easy to put the washing liquid into the second input unit 32 (automatic input unit and input port). Here, first, with reference to FIG. 11A, an example of a case where a washing treatment liquid is introduced from the washing machine 101 of the comparative example to the second input unit 32 (automatic input unit) will be described. Subsequently, an example of a case where the washing machine 1 is put into the second loading unit 32 (automatic loading unit) by the washing machine 1 of the present embodiment will be described with reference to FIG. 11B. FIG. 11A is an explanatory diagram showing the input state of the water washing treatment liquid in the washing machine 101 of the comparative example. FIG. 11B is an explanatory diagram showing the input state of the water 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 the second, which is arranged between the water supply unit 20 (water supply means) and the first input unit 31 (manual input unit), like the conventional washing machine. Device of the input unit 32 (automatic input unit).

As shown in FIG. 11A, in the washing machine 101 of the comparative example, the second input part 32 (automatic input part) is arranged behind the first input part 31 (manual input part). In the washing machine 101 of this comparative example, when the user puts the washing liquid into the second input portion 32, the housing 11 will interfere with the carcass (or bottom) of the replenishing container 91 for the washing 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 part 32, and in this state, the washing liquid is injected into the second input part 32. In the washing machine 101 of this comparative example, the water washing treatment liquid is introduced into the second input part 32 from a relatively high position, and therefore, there is a possibility that the water washing treatment liquid cannot be input into the second input part 32 in a smart manner and overflow. As a result, in the washing machine 101 of the comparative example, there is a possibility that the surroundings of the second input portion 32 will 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 liquid into the second input portion 32, the housing 11 does not interfere with the body portion (or the bottom) of the replenishing container 91 for the washing liquid. Therefore, in the washing machine 1 of the present embodiment, the discharge port of the replenishment container 91 can be put into the second input part 32 by the second input part 32. Since the washing machine 1 of the present embodiment is such that the water washing treatment liquid is introduced into the second input portion 32 from a relatively low position, the water washing treatment liquid can be introduced into the second input portion 32 without overflow. As a result, in the washing machine 1 of this embodiment, it is possible to suppress the water washing treatment liquid from contaminating the periphery of the second input portion 32.

<Arrangement relationship between the inlet cover (first cover) and the tank storage cover (second cover)> Hereinafter, with reference to FIG. 12, the arrangement relationship of the inlet cover 43a and the tub storage cover 15 will be described. FIG. 12 is an explanatory diagram showing the arrangement relationship of the inlet cover 43a (first cover) and the tub storage cover 15 (second cover).

As shown in FIG. 12, the washing machine 1 is provided in the upper front part of the housing 11 and includes a discharge port cover 43 a and a tub storage cover 15. The inlet cover 43a is a first cover that seals the second inlet 32. The tub 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 respectively configured to be openable and closable from the front to the back in the longitudinal direction (refer to FIGS. 2 and 3).

As shown in FIG. 12, the tank storage cover 15 (second cover) is arranged at a position that abuts on the inlet cover 43a (first cover) when it is closed. When the tank storage cover 15 is closed, assuming that the inlet cover 43a is open, it may be in contact with the inlet cover 43a to automatically close the inlet cover 43a. That is, in the washing machine 1, it is assumed that the user forgets to close the inlet opening cover 43a, and the user can automatically close the inlet opening cover 43a as long as the user closes the tub storage cover 15.

<For control> Fig. 13 is a functional diagram of the water quality sensor 35. The pair of electrodes 36A and 36B are connected to the coil 38a to form a resonance circuit 38. The coil 38a is magnetically coupled to the coil 39a, and the coil 39a is connected to the oscillation circuit 39. The pair of electrodes 36A, 36B, the coil 38 a, the coil 39 a, and the oscillation circuit 39 form a water quality sensor 35. The oscillation circuit 39 sends a signal equivalent to the electrical conductivity between the electrodes to a microcomputer (hereinafter referred to as a microcomputer) 110 of the control device 100, and the characteristics are changed by the electrostatic capacity of the component, that is, the capacitor, making it easy to read The resistance value of the water quality varies.

Fig. 14 is a functional block diagram illustrating the configuration of the control device 100 of the washer dryer in this embodiment. The control device 100 is structured around the microcomputer 110. The microcomputer 110 includes an operation mode pattern database 111, a process control unit 112, a rotation speed calculation unit 113, a clothes weight calculation unit 114, a conductivity measurement unit 115, and a washing amount/washing time determination unit 116 , And the detergent state discriminating unit 117, the foaming discriminating unit 118, and the water washing treatment liquid are put into the discriminating unit 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 controlling each process of the washing process, the washing process, the dehydration process, and the drying process according to the operation mode pattern called from the operation mode pattern database 111.

In each process, the process control unit 112 has a function of controlling the water supply unit 20, the drain valve 65, and the switching valve 64. In addition, the process control unit 112 includes: driving and controlling the motor 23a of the driving device 23 through the motor drive circuit 121, switching the clutch mechanism 23b through the clutch drive circuit 122, and turning on/off the heater switch 123 The OFF control controls the function of energizing the heater 71, controlling the fan 72 via the fan drive circuit 124, controlling the circulation pump 17 via the circulation pump drive circuit 125, and controlling the transfer pump 46 via the transfer pump drive circuit 126 .

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

Details will be described later.

The water washing treatment liquid input judging unit 119 has an operation mode pattern of ON/OFF settings for inputting the water washing treatment liquid input from the operation switch 14 from the operation mode pattern database 111, based on The washing amount determined by the washing amount/washing time determination unit 116 is a function of the transfer pump driving circuit 126 to control the transfer pump 46.

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

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

In addition, in step S1, as long as the setting of the input of the washing liquid is ON, the temperature of the water or surrounding air is measured by the temperature sensor 26b or the temperature sensor 26c.

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

In step S3, the washing amount/washing time determining unit 116 displays the amount of washing to be put in and the time required for completion of the washing on the operation panel 14 according to the amount of clothes, the temperature of the tap water and the hardness of the water . In addition, the water temperature of the tap water and the hardness of the water are those detected in the previous washing operation (step S30) and memorized in the washing amount/washing time determination unit 116. The water temperature and water hardness of tap water do not change sharply every day but only gradually. Therefore, the water temperature and hardness of tap water measured during the previous washing can be used to determine the amount of wash. In addition, in the initial operation after the installation of the washer-dryer, the initial value (for example, water temperature 15°C, hardness 120 ppm) that does not deteriorate with water washing performance is used.

And in step S1, as long as the setting of the water washing treatment liquid input is ON, in step S3, according to the washing amount determined by the washing amount/washing time determining unit 116, the conveying pump drive circuit 126 will convey The pump 46 controls the supply of the water washing treatment liquid to the first input part 31 through the conveyance path 53.

In step S4, first, the process control unit 112 opens the water supply unit 20 and supplies the first injection unit 31 and the outer tank 22 with detergent and water. When the predetermined water level is reached, the water supply unit 20 is closed. In addition, when water is supplied to the first input portion 31, the first water supply path 51 and the second water supply path 52 are divided, so that the water washing treatment liquid remaining on the transport path 53 can be transported to the first input portion 31.

In step S5, the temperature of the water containing the lotion to be supplied 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 mass sensor 35 measures the conductivity.

Here, using FIG. 16, the water supply to the outer tank in step S4, the detergent state determination unit 117 in the water temperature and conductivity measurement in step S5 will be further described.

Fig. 16 is a flow chart for determining the operation time of the detergent melting operation according to the water temperature and conductivity of the tap water.

In step S51, the temperature (water temperature) of the water containing detergent supplied to the water is measured by the temperature sensor 26b (or the temperature sensor 26c). In step S52, the detergent state determination unit 117 is It is judged that the type of lotion is liquid lotion or powder lotion (judgment of lotion state). In addition, the determination of the state of this lotion is described later using FIG. 17. When the measured water temperature is higher than the threshold value t1 (Yes in step S53), the process proceeds to step S54, and when the threshold value is less than t1 (No in step S53), the process proceeds to step S55. Here, because it has been experimentally determined that the dissolution state of the lotion will change greatly around about 10°C, so in this embodiment, 13°C, which is slightly higher than 10°C, is also considered to be uneven Set to the threshold value t1.

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

Considering the solubility of liquid lotion and powder lotion in water, it is better for the lotion melting time T0 to be longer than the lotion melting time T1, or the lotion melting time T3 to be longer than the lotion melting time T2. Furthermore, when the water temperature is low, the lotion is not easily dissolved in water, so it is preferable that the lotion melting time T2 is longer than the lotion melting time T0, or the lotion melting time T3 is longer than the lotion melting time T1.

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

Further, in step S1, when the setting of the water washing treatment liquid input is ON, the determination in step S54 and step S55 becomes (Yes), and the lotion melting time becomes the lotion melting time T0, and The lotion melting time T2, but when the user mistakenly puts the powder lotion into the first pouring part 31, the determination in step S54 and step S55 becomes (No), the lotion melting time, It may be determined that the lotion melting time T1 and the lotion melting time T3 are acceptable.

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

Next, the electric conductivity measurement part 115, the lotion state determination part 117, and the foaming determination part 118 in the lotion state determination of step S52 are demonstrated using FIG.

Fig. 17 is a flowchart for determining the type of lotion by conductivity, estimating the foaming easiness from the result, and switching the washing time, the amount of water, and the number of rotations of the motor.

In the mixing process in step S520, the process control unit 112 controls the motor 23a through the motor drive circuit 121, and rotates the water tank 21 and the rotary wing 21b to wash the water toward the outer tank 22 and the water tank 21 When the agent and water flow, the lotion and water can be homogenized.

In step S520, in the case of powder lotion, it is difficult to uniformize the lotion and water, so it is necessary to control the rotation number of the motor 23a at a high level. However, in the case of liquid lotion, because the lotion and water are uniform It is easy to reduce the rotation speed of the motor 23a at a low level. Furthermore, in this embodiment, in step S520, the means for uniformizing the rotation of the water tank 21 and the rotor 21b are implemented, but the means for fixing the water tank 21 to rotate the rotor 21b and the circulation pump 17 The mixing process may also be implemented by means such as homogenization.

And step S520, because it is a process of stirring the highest concentration of detergent and water through the water washing process, the risk of foaming can be suppressed by suppressing the rotation number of the motor 23a.

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

In step S521, the conductivity measuring unit 115 measures the conductivity of the water that has been homogenized by the water quality sensor 35. In addition, when measuring conductivity, in order to improve the measurement accuracy, the water supply from the water supply unit 20 to the outer tank 22, the circulation generated by the circulation pump 17, the rotation of the water tank 21 and the rotor 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 washing liquid does not foam.

Therefore, in step S520, since the water flow occurring in the outer tank 22 is weakened by suppressing the low rotation number of the motor 23a, the time until the rotation of the motor 23a stops and the water flow in the outer tank 22 can be shortened Slowing the time until it is suitable for measurement, a measurement system that can increase the conductivity in a short time.

Fig. 20 is a result of measuring the unevenness of the conductivity caused by the rotation number of the motor 23a in step S520. In the case of high-speed rotation, the maximum/minimum detection variance of the conductivity is varied, and by controlling the low-speed rotation, the maximum/minimum detection variance of the conductivity can be suppressed.

In step S522, when the conductivity is smaller than the threshold value EC1 (Yes), the process proceeds to step S524, and it is determined that it is liquid lotion (concentration), and the characteristics of the water quality sensor 35 are switched according to this. When the conductivity is equal to or greater than the threshold value EC1 (No in step S522), and is smaller than the threshold value EC2 (Yes in step S523), the process proceeds to step S525 to determine that it is a liquid detergent (washed twice). When the electrical conductivity is equal to or greater than the threshold value EC2 (No in step S523), the process proceeds to step S526, which is determined to be a powder detergent, and the washing time, the amount of water, and the number of motor rotations are changed to switch the washing method. For example, powder lotion has a tendency to foam easily, so compared with the case of liquid lotion (concentration), by shortening the washing time, increasing the amount of water, the concentration of the lotion is reduced, and the number of rotations of the motor is reduced, so that It is not easy to foam, and to suppress foaming, you can prevent the degradation of cleaning performance and insufficient cleaning. Liquid lotion (concentrated) has a tendency to be less foamy, so compared to the case of powder lotion, by prolonging the washing time, increasing the amount of water to reduce the concentration of the lotion, and increasing the number of rotations of the motor, there is a risk of foaming. Low state improves cleaning performance. Since the conductivity of liquid lotion tends to be in the middle of powder lotion and liquid lotion (concentration), by placing the washing method in the middle, it can become a proper cleaning method. Therefore, because it is not foaming, but by detecting the type of detergent, it can be changed to the most suitable washing method, and there is no need to provide a sensor for foam detection. In addition, it is not necessary 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, the foaming determination unit 118, in step S524, step S525, and step S526, is not only the type of lotion, it is easy to foam by detecting the water temperature, water hardness, bath water usage status, etc. The degree of the element can improve the accuracy of the foaming determination unit 118.

The concentration type liquid lotion that can be used only once in the washing operation is smaller than the liquid lotion requiring two times in the washing operation. Since the electrical conductivity becomes smaller, the number of washings is changed from the judgment result in the foaming judgment section 118 Can also.

In step S6 in FIG. 15, the process control unit 112 generates the solution 23 by rotating the water tank 21 and the rotor 21b only by driving the motor 23a based on the detergent melting time determined in step S5. High concentration lotion solution. In addition, the method of generating a high-concentration lotion solution is not limited to the method of rotating both the water tank 21 and the rotor blade 21b, and only the method of rotating the rotor blade 21b or the reverse rotation by the circulation pump 17 may be used.

In step S7, the conductivity measurement unit 115 measures the conductivity of the generated lotion solution by the water quality sensor 35, and the lotion state determination unit 117 re-evaluates the type of the determined lotion and determines The concentration of the lotion actually put in. Since the generated lotion solution dissolves the lotion in a certain amount of water, the change in the concentration of the lotion can be detected as the amount of change in conductivity. When the input amount of the detergent is large (the concentration of the detergent is high), the electrical conductivity becomes larger than when the input amount of the detergent is small (the concentration of the detergent is low). Therefore, even if the foaming determination unit 118 determines the washing operation as one time, the washing operation can be changed to two times when the amount of detergent input is large. In addition, in this step S7, in order to improve the measurement accuracy of the conductivity, once the water tank 21 and the rotor 21b rotating to dissolve the detergent are stopped, the rotation starts again 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 feeds water from the water supply unit 20 while rotating the water tank 21 and the rotary blade 21b to a water amount (water level) smaller than that in the subsequent washing process (S13 to S19). . In addition, since the water supply to the first input section 31 is also performed at the same time, the water branched to the first water supply path 51 and the second water supply path 52 can also wash the conveyance path 53 at the same time.

And in step S1, as long as the setting of the water washing treatment liquid input is ON, the process control unit 112 is based on the temperature measured by the temperature sensor 26b or the temperature sensor 26c in step S1, from The water supply time of the water supply unit 20 is changed.

For example, in step S1, the temperature measured by the temperature sensor 26b or the temperature sensor 26c is low (<13°C), because it indicates that the water temperature or the surrounding temperature is low, so the lotion/ The characteristics of the softener change (the viscosity becomes higher). In this case, since the cleaning of the conveyance path 53 is not easy, it is necessary to lengthen the water supply time from the water supply unit 20. (Figure 21) On the other hand, in step S1, the temperature measured by the temperature sensor 26b or the temperature sensor 26c is high (≧13°C) because it indicates the water temperature or the surrounding temperature. The temperature is high, so the properties of the lotion/softener change (viscosity decreases). In this case, since the cleaning of the conveyance path 53 is easy, the water supply time from the water supply unit 20 may be shortened.

In addition, in the rotating water supply in this step S8, the water supply (water pipe cleaning) which supplies water from the second water supply path 52 to the conveyance path 53 and the water supply which supplies direct water from the main water supply path 55 to the outer tank 22 (main water supply) ) Simultaneously, but as described above, the temperature detected by the temperature sensor 26b is low. Since the detergent easily adheres to the piping, the main water supply is stopped after a predetermined time, and the water is supplied only by extending the time for washing the piping.

In step S9, the laundry is washed with a high-concentration detergent solution in a state where the amount of water is smaller than that in the subsequent washing process (S13 to S19). Hereinafter, in a state where the water level is lower than the current washing process, the operation of permeating the laundry with a high-concentration detergent solution while rotating the rotor 21b by the driving device 23 is called high-concentration washing. In addition, although the high-concentration washing process in this embodiment is operated at a certain water level without water supply, it may be operated while water is being supplied. However, the lotion melting operation in step S6 is not included in the high-concentration washing process for those who perform another process (non-continuous) before reaching a predetermined water level.

In this embodiment, the liquid lotion and liquid lotion (concentrated) are washed at a high concentration while rotating the motor (rotating wing 21b) at a higher rotation number than the powder lotion. net. This makes it possible to suppress foaming when powder washing is used when washing at a high concentration where foaming is easy, and to improve the washing power when using liquid washing.

Furthermore, in the present embodiment, the operation time of the conventional high-concentration washing process of about 30 seconds is set to a length of about 2 minutes and 30 seconds. In this way, by prolonging the operation time of the high-concentration washing process, it becomes possible to effectively remove grease from food. On the other hand, it is also necessary to consider the need to shorten the overall washing time by "short time (short for shortened time in Japan)". Here, the operation time of the high-concentration washing process is increased, on the other hand, it is better to shorten the operation time of the washing process.

Fig. 18 is a graph showing how the cleaning performance (cleaning ratio) was tested when the ratio of the operating time to the high-concentration cleaning process of the present cleaning process was changed. According to this figure 18, by setting the operation time of the high-concentration washing process (the ratio of high-concentration washing) to the operating time of the washing process at 15% or more, it is possible to improve the ratio (high-concentration washing Net ratio = 4%) Higher washing ratio. If the ratio of high-concentration washing is further set at 20% or more, it is expected that the washing ratio will be greatly improved. In addition, if the ratio of the present washing is too small, on the contrary, the washing ratio deteriorates, so the ratio of high-concentration washing is preferably 35% or less.

Furthermore, in this embodiment, when determining the condition of the powder lotion by means of determination means (conductivity detection means for detecting the conductivity of the liquid in the outer tank 22) to determine the type of lotion to be charged, Compared with the case where the liquid detergent is discriminated, the rotation speed of the rotary blade 21b during the high-concentration cleaning process can be reduced. Therefore, even in the case of a powder lotion that is easy to foam, the operation time of the high-concentration washing process can be lengthened while suppressing foaming, and the oil stain can be effectively removed.

Next, the case of the washing machine without the circulation pump 17 will be described. When there is no circulation pump 17, especially in the low water level state, it is difficult for the laundry to spread a high-concentration detergent solution from above. Therefore, a difference in water content will occur between the upper and lower parts of the laundry, and the operation of the laundry will slow down, which may cause uneven washing. Here, in the present embodiment, the water washing laundry stacked on the center part and the water washing laundry adhering to the end part are distributed in the center part and the end part (near the inner wall) of the water tank 21 by spreading the washing water in advance The movement is good, even if the water level is low, the difference in water content of the laundry can be suppressed. The specific structure is as follows.

Fig. 19 shows the state of the poured washing water from the water injection hose 51a into the water tank 21. As shown in the figure, the washing water is distributed substantially linearly toward the center (Wa), the end (Wb), and the intermediate portion (Wc) between the end and the center of the water tank 21. Thereby, not only the ends but also the center can be sprayed (spray water) from the water supply stage to the entire washing tank, so that the entire clothes can be easily hydrated, and the cloth movement during washing becomes good. Uneven washing can be suppressed. .

In step S10, first, the laundry weight calculation unit 114 calculates the weight of the laundry in a state containing water. Then, the cloth quality (water absorption) of the clothes is determined from the weight of the clothes in the state of water not including the water calculated in step S1 and the weight of the clothes in the state of water including the water calculated in step S10. The cloth according to the judged cloth 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 detergent increases, and since the cleaning power is increased, the washing time can be shortened. By measuring the water temperature before the washing process, for example, the water temperature can be accurately detected during washing with hot water bathed, 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 steps S18 and S19.

In this way, the foaming easiness during the washing process is to measure the conductivity of the washing liquid using the water quality sensor 35, which is controlled by the foaming discriminating section 118, so that the washing time can be controlled (shortened or extended). The washing amount/washing time determination unit 116 is a list table which memorizes the washing time (shortened or extended time) determined in accordance with the degree of contamination in advance. In addition, the complex threshold value may be set based on the cloth amount calculated in step S1.

When the washing is finished, the unbalanced state of the laundry is monitored in step S20, and it is judged whether or not to move 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 drainage is completed, in step S22, the process control unit 112 rotates the water tank 21 to dehydrate the water (washing water) contained in the laundry.

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

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

The process control unit 112 closes 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 rotates the water tank 21 to dehydrate the water (washing water) contained in the laundry (step S27).

Steps S23 and S25 are performed by the rotary rinsing, when the foaming determination unit 118 is determined and the number of cleanings is determined to be one, the steps S23 to S27 are skipped by sending a message to the process control unit 112 The instruction becomes a one-time cleaning operation.

When the dehydration is normally terminated, the outer tank 22 is in a state of no water, and the water quality sensor 35 is operated to measure the conductivity of the water (step S28). The conductivity measured here is memorized as an initial value in the conductivity measurement unit 115 and is used for determining the failure of the water quality sensor 35 and correcting the change over time caused by the adhesion of dirt to the electrode unit.

The process control unit 112 closes the drain valve 65, opens 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 measurement 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 washing amount/washing time determination unit 116, and are used to determine the next washing amount and washing time.

In addition, in step S1, as long as the setting of the washing treatment liquid input is ON, the water temperature and the conductivity of the washing water in step S30 are measured to calculate the hardness of the water, and then determined according to the washing amount/washing time determining unit 116. The determined softening amount is controlled by the transfer pump drive circuit 126, and the transfer pump 46 is controlled by the transfer path 53 to supply the first washing unit 31 with the washing liquid.

The process control unit 112 feeds water up to the set water level (step S31), agitates the laundry while rotating the rotary wing 21b (or the water tank 21) while the washing water is stored in the outer tank 22, and opens the valve of the water supply unit 20 , The softener is poured into the water tank 21 (step S32). In addition, since the water supply to the first input portion 31 is also performed simultaneously, the first water supply path 51 and the second water supply path 52 are divided, and the water washing treatment liquid remaining on the transport path 53 can be transported toward the first input portion 31.

At this time, in step S1, as long as the setting of the water washing treatment liquid input is ON, the process control unit 112 may change the temperature measured in step S1 according to the temperature of the temperature sensor 26b or the temperature sensor 26c. The water supply time from the water supply unit 20 is changed.

In this way, when the softener is added in step S32, water supply (pipe cleaning) is performed to supply water to the conveying path 53 (including the switching valve 64 and the conveying pump 46), but the temperature detected by the temperature sensor is higher than a predetermined value In the lower case, the softener tends to adhere to the piping, so the piping cleaning time is increased. In addition, when the temperature detected by the temperature sensor is higher than a predetermined value, the time for washing the piping may be shortened, and the overall operation time may be shortened.

In this step S33 to step S35 (process 2 of washing), by operating the water quality sensor 35 to detect the change in the conductivity of the washing water, it becomes possible to detect the washing degree of the laundry. By the way, since the water quality sensor 35 in this embodiment is provided at the lower portion (bottom) of the outer tank 22, during the cleaning process, the water quality sensor 35 can be measured under the state where the water quality sensor 35 is submerged. Conductivity.

In this way, by using the water quality sensor 35 to measure the conductivity of the washing water during the washing process, the washing time can be controlled (shortened or extended). A list of cleaning time (shortened or extended time) determined by the amount of change in the conductivity of the cleaning water is memorized in advance. In addition, the amount of change in the conductivity of the washing water may be determined by comparing with the 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/extending the washing time. Therefore, even if the cleaning state determination unit 117 determines that the cleaning operation is one time, a concentrated type of liquid detergent can be used, and if the foaming determination unit 118 determines that the cleaning operation is one time, if it is determined as When cleaning is insufficient, additional cleaning operation can be performed.

In addition, the time point at which the water quality sensor 35 is operated during the cleaning process is not limited to the steps S33 to S35, and the steps S23 and S25 are activated to control (shorten or extend) the cleaning time.

In step S23 or step S25, the washing time may be controlled (shortened or extended) according to the cloth quality of the clothing determined in step S10.

If the stagnation washing is finished, the imbalance of the laundry is monitored, and it is judged whether or not to move 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 start-up at the time of dehydration, it may be moved 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 dehydrate the water contained in the clothes (step S38). In this step S38 (dehydration process), by using the water quality sensor 35 to measure the water dehydrated from the laundry, it becomes possible to determine the amount of moisture contained in the laundry. During the dehydration process, the water tank 21 rotates to separate the water contained in the 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 portion 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 conductivity of the water during dehydration.

That is, in the water quality sensor 35 at the time of dehydration, as water flows into the groove of the water quality sensor 35, the detected value (conductivity) changes according to the amount of water passing through. For example, when the laundry is a person with high water absorption such as bath towels, the amount of discharged water increases and the detected value (conductivity) becomes high. On the other hand, for example, when the 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 conductivity of the water dehydrated from the clothes during the dehydration process, the dehydration time can be controlled (shortened or extended). The washing amount/washing time determination unit 116 is a list table for determining the spin-drying time (shortened or extended time) memorized in advance. In addition, the 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 operated during the dehydration process is not limited to step S38, and it is operated at steps S22, S24, and S27 in other dehydration processes to control (shorten or extend) the dehydration time. can.

<Main features of washing machine (structure)> In this embodiment, since the conventional washing machine has the following problems, the washing machine 1 which can solve this problem is intentionally provided.

(1) A conventional washing machine includes a hose connected to a water tank (laundry and dehydration tank) in a manual input unit and a water washing treatment liquid input device. That is, a conventional washing machine is provided with a hose of a first system that connects a manual input unit and a water tank (laundry and dehydration tank), and a second that connects a water treatment liquid injection device and a water tank (laundry and dehydration tank). System hoses, multiple hoses. Since such a conventional washing machine has a large number of hoses, there is a problem that there is a relatively high risk of water leakage caused by falling off of the hose and rupture of the hose.

In this regard, as shown in FIG. 6, the washing machine 1 of the present embodiment transports the washing liquid stored in the tub 42 from the tub 42 toward the first input portion 31 through the transport path 53 and through the input path 54 The water is poured into the water tank 21 from the first feeding part 31.

In the washing machine 1 of this embodiment, the hose connecting the water 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 the present embodiment can reduce the risk of water leakage caused by the falling off of the hose and the rupture of the hose in the part of the deleted hose. As a result, the washing machine 1 of this embodiment can reduce the risk of water leakage to 1/2 of the conventional washing machine, and can improve the reliability of this part.

(2) The conventional washing machine requires the supply of water to both the manual input unit and the water washing treatment liquid input device when the detergent is put in, so there is a problem that the amount of water used when the detergent is put in is relatively large.

In this regard, as shown in FIG. 6, in the washing machine 1 of the present embodiment, since the water supplied to the water washing treatment liquid input device 30 is supplied to the first input portion 31, the amount of water used when the detergent is input can be reduced. As a result, in the washing machine 1 of this embodiment, the amount of water used when the detergent is put in can be reduced to, for example, 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 of the housing, and the manual input part is arranged in front of it. In addition, between the water supply means and the manual input unit, and at the side of the water tank (washing and dewatering tank), a tub and an input unit (automatic input unit) of the water washing treatment liquid input device are arranged. Therefore, the conventional washing machine is provided with an input unit (automatic input unit) in which the water washing treatment liquid input device is placed in a place away from the position where the user stands. Therefore, the conventional washing machine has a problem that it is difficult for the user to put in the water washing treatment liquid when the user puts the water washing treatment liquid into the automatic loading part, 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) in a place close to the position where the user stands. Therefore, in the washing machine 1 of the present embodiment, the water washing treatment liquid can be easily charged into the second loading portion 32 (automatic loading portion). The washing machine 1 of this embodiment can improve the convenience of use.

(4) In the conventional washing machine, the automatic input part of the water washing treatment liquid input device is arranged behind the manual input part. Therefore, in the conventional washing machine, when the user holds the replenishing container of the washing treatment liquid toward the automatic loading portion and puts the washing treatment liquid into it, the frame body will interfere with the carcass portion (or the bottom) 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 insertion part, and it is necessary to put the washing liquid in the automatic insertion part in this state. Such a conventional washing machine has a problem that the washing treatment liquid may be poured into the automatic loading section from a relatively high position, and therefore there is a possibility that the washing washing liquid may not be poured into the automatic loading section in a smart manner and overflow.

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 the present embodiment, when the user holds the replenishing container 91 of the washing treatment liquid into the second loading part 32 (automatic loading part), the casing 11 does not contact the carcass of the replenishing container 91 Part (or bottom) conflict. Therefore, in the washing machine 1 of the present embodiment, the discharge port of the replenishment container 91 can be put into the second input part 32 by the second input part 32. Since the washing machine 1 of the present embodiment is such that the water washing treatment liquid is introduced into the second input portion 32 from a relatively low position, the water washing treatment liquid can be introduced into the second input portion 32 without overflow. As a result, in the washing machine 1 of this embodiment, it is possible to suppress the water washing treatment liquid from contaminating the periphery of the second input portion 32.

(5) The conventional washing machine has a problem that when a user puts the washing liquid into the automatic loading part, the washing liquid may overflow the operation panel, causing a malfunction of the buttons and the touch panel.

Regarding this, the washing machine 1 of the present embodiment is as described in the aforementioned item (4), and can be wisely charged into the second loading section 32 (automatic loading section) without overflowing the washing liquid. Therefore, in the washing machine 1 of the present embodiment, it is possible to suppress erroneous operation of the buttons and the touch panel caused by the water washing treatment liquid overflowing the operation panel 14 (refer to FIG. 1 ).

(6) In the automatic injection part of the water washing treatment liquid introduction 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 input unit is provided behind the manual input unit. Therefore, a conventional washing machine (especially, a vertical washing machine) has a problem that it is inconvenient to use the water washing treatment liquid input device.

Regarding this, as shown in FIG. 5, the washing machine 1 of the present embodiment has a relatively large amount of washing treatment liquid into which the second injection unit 32 (automatic injection unit) is provided than the first injection unit 31 (manual injection Department) further forward. Therefore, the washing machine 1 of this embodiment can improve the ease of use of the water 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 portion of the housing. In the conventional washing machine of this configuration, since the distance between the tub and the drying unit of the water washing treatment liquid input device is relatively close, it is possible to gel the water washing processing liquid contained in the tub by heat from the drying unit Subject.

In this regard, as shown in FIG. 4, in the washing machine 1 of the present embodiment, the drying unit 71 is disposed at the upper rear portion of the housing 11, and the water washing treatment liquid input device 30 is disposed at the upper front portion of the housing 11. That is, in the washing machine 1 of the present embodiment, the water 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 water washing treatment liquid contained in the tub 42 by the heat from the drying unit 71.

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

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

(9) A conventional washing machine is a tank where a washing treatment liquid input device extends in the front-back direction at a side of a water tank (washing and dewatering tank), and the tank cannot be removed. Therefore, the conventional washing machine has a problem that the tub and the like cannot be washed.

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

(10) The conventional washing machine is provided with a cover that seals the automatic insertion portion. The 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 opening direction of the cover is opposite to the user's dominant hand.

In this regard, as shown in FIGS. 7 and 8, the washing machine 1 of the present embodiment is configured such that the inlet port cover 43a (first cover) can be opened and closed in the longitudinal direction from front to back. Therefore, the washing machine 1 of the present embodiment can open the inlet cover 43a (first cover) regardless of the dominant hand. As a result, the washing machine 1 of the present embodiment can easily add (replenish) the water-washing treatment liquid to the second input section 32 (automatic input section) regardless of the dominant hand.

(11) The conventional washing machine has a problem that the water washing treatment liquid leaks out of the tub of the water washing treatment liquid input device when the user forgets to close the cover for sealing the automatic insertion portion and performs water washing.

Regarding this, as shown in FIG. 12, the washing machine 1 of the present embodiment assumes that the user forgets to wash the water in a state where the input port cover 43a (first cover) is closed, by storing the tub 15 ( The second cover) is closed, and the inlet cover 43a can be automatically closed. Therefore, even in this case, the washing machine 1 of the present embodiment can suppress the leakage of the water-washing treatment liquid from the tub 42 of the water-washing treatment liquid input device 30.

(12) A conventional washing machine is a part of the piping path through which the washing liquid passes through when the washing liquid contained in the tub of the washing liquid input device is sent out by air pressure to the water tank. . The conventional washing machine has a problem that it is difficult to wash the parts where water does not pass.

In this regard, as shown in FIG. 6, although the washing machine 1 of the present embodiment sends the washing treatment liquid contained in the tub 42 of the washing treatment liquid input device 30 toward the transportation path 53, the water is transported through the transportation Any part of the path 53. Therefore, in the washing machine 1 of the present embodiment, the conveyance path 53 can be reliably washed.

As described above, according to the washing machine 1 of the present embodiment, it is easy to put in the water washing treatment liquid, and the convenience of use 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 for easy understanding of the present invention, and are not limited to those who need to 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 may be added, deleted, or replaced.

For example, the tank 42 preferably has claw-shaped engagement means and the like, which can be strongly engaged with the shell 41.

And 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 in either or both of the tank 42 and the shell 41.

Also, for example, the input port cover 43a (first cover) may have a structure that slides open and closes from front to back.

<Main features of control> In the washing machine 1 of the present embodiment, when the setting of the water washing treatment liquid input is ON in step S1, the detergent injected into the outer tank 22 becomes a liquid detergent, so that step S520 can be suppressed The number of rotations of the motor 23a in the middle is controlled. Thereby, since the water flow occurring in the outer tank 22 becomes weaker, the time until the rotation of the motor 23a stops at step S521 and the time until the water flow in the outer tank 22 becomes slow until it is suitable for measurement can be shortened. Time improves the measurement accuracy of conductivity.

And by measuring the conductivity of the water containing the lotion, it is determined whether 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), and the dissolution time of the lotion is set longer than that of the liquid lotion. This results in a longer melting action than the liquid lotion lotion, which prevents the powder lotion from dissolving and remains, and can be used throughout the high-concentration lotion solution during the pre-washing process, which can improve the cleaning performance.

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

And in this embodiment, by measuring the temperature of the water containing the lotion, the time for the action of melting the lotion according to the water temperature can be changed. (Refer to S56, S57, S58, S59). That is, for a case where the temperature of the water is higher than the threshold value t1, the lotion melting time is easily melted. If it is a liquid lotion, it is set to the lotion melting time T0 (S56), and if it is a powdered lotion, the lotion is melted. Time T1 (S57). For the case where the water temperature is below the threshold t1 and the lotion is not easy to dissolve, the lotion dissolution time is set to the lotion dissolution time T2 (S58), and the powder lotion is set to the lotion dissolution time T3 (S59) . In this way, the melting time of the lotion is set to be longer than that of the liquid lotion (T1>T0, T3>T2). When the water temperature is high, it is set by shortening (T0<T2, T1<T3). The time for the lotion melting operation is shortened, and the driving time of the circulation pump 17 (either 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 the conductivity of the water containing the detergent is lower than the threshold value EC1 (for example, if the cleaning operation is one time or the liquid detergent of the concentrated type) (S522 is Yes), set the number of cleaning operations to 1 Times (refer to S524), when the conductivity is equal to or greater than the threshold value EC1 (for example, when the cleaning operation is liquid detergent twice) (S522 is No), the number of cleaning operations is set to two (refer to S525, S526) . In this way, the state of the detergent (the type of detergent) can be discriminated based on the electrical conductivity, and the appropriate number of cleaning operations can be set, so the time for the laundry operation can be shortened, and the operation time of the motor 23a during the cleaning process can be shortened. , Suppress the number of rotations to 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 operation (S6), and it is preferable to set the time of the lotion melting operation according to the type of the 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 can be discriminated (concentrated) Type of liquid lotion, liquid lotion, powder lotion) degree of conductivity difference. Based on this judgment result, the detergent dissolution action is performed (S6), and then again, by measuring the conductivity (S7), it can be re-evaluated whether the judgment result of the detergent type is wrong, and because of the amount of detergent put in (Concentration of lotion) can also be measured as the difference in electrical conductivity, so that the discrimination of the state of the lotion can be optimized.

The detergent state determination unit 117 corrects the electrical conductivity threshold value EC1 and the threshold value EC2 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, the threshold value of the electric conductivity can be corrected by the water temperature and the electric conductivity (hardness) of the water, so that the state of the lotion can be optimally determined.

In the present embodiment, the person who changed the number of washing operations based on the conductivity of the washing liquid has been described, but for example, a configuration may be used in which the amount of water used in the washing operation is changed. Specifically, the higher the conductivity, the more controlled the configuration is to increase the amount of water used in the cleaning operation. In other words, when there is a lot of detergent input (the concentration of the detergent is high), the detergent may foam excessively during the cleaning operation, but by increasing the amount of water used, the foaming of the detergent can be reduced . In addition, depending on the conductivity of the water washing solution, a configuration may be adopted in which the operation time of the pre-washing process and the present washing process and the amount of water used are changed.

As described above, although the washing machine of this embodiment has been described using a vertical type washer-dryer in which the rotation axis of the washing and dewatering tank is substantially vertical, the rotation axis of the rotating drum (washing and dewatering tank) is A drum-type washing and drying machine in a substantially horizontal direction may be used, and a vertical type washing machine or a drum-type washing machine that does not have a drying function may be used.

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

<Main features of control for changing the water supply time of piping> According to the washing machine 1 of the present embodiment, even if the characteristics of the detergent/softener are changed, the detergent/softener can be washed without leaving the pipe path. In addition, when there is no change in the characteristics of the lotion/softener, the washing operation can be performed while suppressing the extension of the operation time and the increase in the amount of water used. Further, by preventing the lotion/softener from remaining in the piping path, it is possible to suppress the cause of piping clogging and the occurrence of odor. Furthermore, it is possible to suppress the risk of clogging of the piping when the other water washing treatment liquid is put in the state where the water washing treatment liquid remains in the conveyance path 53.

Specifically, when the temperature detected by the temperature sensor is higher than a predetermined value, by at least increasing the time to feed water to the conveying path 53 from the switching valve 64 to the conveying pump 46, each washing operation will After washing in the conveyance path 53, the effect of suppressing the residual of liquid lotion and softener can be expected. In addition, although the water supply to the conveyance path 53 during the washing process is performed in steps S4, S8, and S12, the change in the water supply time due to the temperature is preferably performed in step S8. Step 4 is the water supply for determining the type of lotion. Since only a small amount of water is supplied, it is difficult to extend the water supply time here. Furthermore, in step S12, since the water is supplied up to the water level of the current washing, it is not good to extend the water supply time from there. Therefore, in this embodiment, the water supply time is changed at step S8 from the detergent determination to the pre-wash.

As described above, although the washing machine of this embodiment has been described using a vertical type washer-dryer in which the rotation axis of the washing and dewatering tank is substantially vertical, the rotation axis of the rotating drum (washing and dewatering tank) is A drum-type washing and drying machine in a substantially horizontal direction may be used, and a vertical type washing machine or a drum-type washing machine that does not have a drying function may be used.
