In other words, the lotion or softener that is put into the inside of the input field 39 is configured to flow out of the first lotion supply pipe 14 through the second lottery supply pipe 41 together with the water to be supplied with water.

The time at which the lotion and the softener are supplied to the respective water tanks 17 are different. As will be described later in detail, the lotion is supplied during the washing process, and the softener is supplied in the final washing process. After the lotion is supplied to the inside of the input field 39, the inside of the input field 39 is cleaned by the water supply. Therefore, even if the softener is supplied to the inside of the same input field 39, the lotion does not remain and is mixed with the softener. Therefore, there is only one input field 39, and the water supply discharge unit 57 and the second water supply pipe 40 for supplying water to the water supply area 39 do not need to be separately provided for the lotion and the softener, so that the configuration can be simplified. .

On the rear of the tank storage container 34, there is provided The cover supporting portion 43 of the support shaft hole 42 for the shaft support that can be opened and closed is described later.

<slot bucket>

In the tank storage container 34, two washing treatment tanks are arranged side by side in the front-rear direction, a softener tank 33 is provided in the front, and a lottery tank 32 is provided in the rear. The softener tank 33 and the detergent tank 32 are disposed substantially symmetrically in front and rear with the first partition wall 35 being held together. In one example, the size of the detergent tank 32 in the front-rear direction is larger than the size of the softener tank 33 in the front-rear direction, and the volume of the lottery tank 32 may be larger than the softener tank 33.

The lottery tank 32 and the softener tank 33 are substantially symmetrical in shape and sandwiched by the first partition wall 35, and have the same configuration except for the difference in the front-rear direction. Therefore, the washing is detailed in FIGS. 6 to 9 The composition of the tanks 32.

In the present embodiment, the lottery tank 32 is detachably partitioned from the upper tub lid portion 44 and the lower tub body 45, and the tub lid portion 44 is in the case of replenishing the lotion or the lotion. When the inside of the tub 32 is washed, it is removed from the tub body 45 by releasing the lock means (not shown). The tank lid portion 44 is provided with a tub handle 44a for holding by the hand when the detergent tank 32 is attached or detached.

When the detergent tank 32 is replenished with a predetermined amount of the lotion, the liquid level of the lotion is formed by a height lower than the boundary between the tub body 45 and the tub lid portion 44, because the washing is performed. The agent does not leak from the boundary between the tub body 45 and the tub lid portion 44 toward the lotion tank 32 Out so best.

When the tub body 45 is formed of a transparent resin such as acrylic resin or polyethylene terephthalate (PET) resin, when the detergent tank 32 or the softener tank 33 is removed from the washing machine body 4, It is best to visually confirm the residual amount of the lotion or softener.

The bottom surface 46 of the tub body 45 is formed in a substantially V shape, and the suction port 48 of the pump means 47 to be described later is provided in a portion where the bottom surface thereof is lowered, because the lotion in the tub can be finally Since it is inhaled, unnecessary waste of the lotion is not produced and is optimal.

<longitudinal barrel>

The detergent tank 32 and the softener tank 33 are configured to have a depth in the front-rear direction, a width in the left-right direction, and a height dimension in the vertical direction, and the depth dimension is the smallest. With such a configuration, since the area of the lotion or softener inside the tank in contact with the air in the tank can be reduced, the moisture evaporates from the surface of the lotion or the softener to make the viscosity of the surface high and the effect of solidification. It is the smallest, and has an effect that the supply operation by the pump means 47 mentioned later can be performed reliably.

<Pocket front and rear configuration and tank depth>

The optimum relationship between the arrangement, size and volume of the detergent tank 32 and the softener tank 33 will be described. Here, it is explained that the capacity of the detergent tank 32 is larger than the capacity of the softener tank 33. This is, for example, the size of each container of a commercially available lotion and softener, and is sold as a supplement. The unit sold is the case where the lotion is larger than the softener.

In the present embodiment, as shown in Fig. 4, the water tank 17 is higher in the front side of the lid body 3, and is disposed to be inclined as it goes downward toward the rear. In this case, the gap between the water tank 17 and the upper surface of the washing machine body 4 is smaller as the front side is larger, and the rear is larger. Therefore, when the detergent tank 32 and the softener tank 33 are juxtaposed in the front-rear direction, it is preferable to arrange the tank having a large capacity in the rear side because the depth in the vertical direction can be increased. In the front side, a tank having a small depth and a small capacity is disposed. In the present embodiment, the detergent tank 32 is disposed at the rear, and the softener tank 33 is disposed in the front.

Further, since the water tank 17 is cylindrical, the gap between the water tank 17 and the upper surface of the washing machine body 4 is larger as the closer to the left and right ends, and the smaller the vicinity of the center. When the detergent tank 32 and the softener tank 33 are juxtaposed in the left-right direction, a tank having a small capacity (softener tank 33) is disposed near the center, and the capacity is disposed on the end side of the casing. A large tank (wash tank 32) is preferred. With such a configuration, the height of the tank (the detergent tank 32) disposed on the end side is higher than that of the tank (softener tank 33) disposed on the side near the center because the tank 32 can be used. The capacity is further expanded and is therefore the best.

<pump>

The tank lid portion 44 is provided with a pump means 47 for sucking the washing treatment liquid from the tub body 45 into the above-described input field 39. In the present embodiment, a configuration of a gear pump of one example of the pump means 47 is used.

The pump means 47 in this embodiment is provided with: An inner portion of the cylindrical detergent tank 32, a pump casing 49 extending downward from the tank lid portion 44, and a suction pipe extending further downward from the bottom surface of the pump casing 49 and having a lower end thereof approaching the bottom surface of the tank body 45. 50. The lower end of the suction pipe 50 is a suction port 48 that is an opening.

As shown in Fig. 9, at the lower end of the pump casing 49, one is a drive gear 51a rotatably supported by the pump drive shaft 60, and the other is rotatable around the pump driven shaft 91. The gear pump 51 constituted by the pair of gears of the driven driven gear 51b that is freely supported can be conveyed from one of the gear meshing portions 52 toward the other by rotating while meshing.

The upper end of the suction pipe 50 is connected to one of the gear meshing portions 52, and the lotion can be sucked through the suction port 48.

The other side of the gear meshing portion 52 is provided with a supply pipe 54 that is disposed in the vertical direction along the pump casing 49. The lower end of the supply pipe 54 is connected to the other of the gear meshing portions 52, and the lotion that is sent from the gear pump 51 is sent. Being supplied.

The gear pump 51 is rotated in the direction of the arrow so as to fill the space formed by the gap between the adjacent teeth of the drive gear 51a and the driven gear 51b and the space formed by the gear pump wall 55 provided near the outer circumference of the gear. The suction port 48 side moves toward the supply pipe 54 side, and the lotion is supplied. Since the operation of the gear pump 51 is as generally known, detailed description thereof will be omitted.

The upper end of the pump casing 49 is a pump cover 53 that covers the upper surface of the pump means 47.

The upper end of the supply pipe 54 extends substantially horizontally in the direction in which the pump cover 53 is separated, and the tip end thereof extends downward, and the tip end thereof is a discharge port 56 for opening the lotion toward the lower side.

<Exhaust and wash>

The second water supply pipe 40 is connected to the water supply discharge unit 57 provided on the side surface of the input field 39 of the tank storage container 34. When the water supply discharge portion 57 is disposed in the vicinity of the discharge port 56, and the water supplied from the water supply discharge portion 57 is disposed in the discharge port 56, the lotion or the softener adhering to the discharge port 56 is not dried and solidified, so the lotion is applied. The clogging of the softener does not occur and the reliability is high.

The optimum position of the water supply discharge portion 57 will be described. When the height of the water supply discharge portion 57 is close to the second partition wall 36, the discharged water passes over the second partition wall 36 and flows into the detergent tank storage area 37 or the softener tank storage area 38. On the other hand, when the height of the water supply discharge portion 57 is too close to the bottom surface, the discharged water does not flow to the discharge port 56, so that the discharge port 56 cannot be washed, and the lotion adhering to the wall surface of the input field 39 cannot be removed. Wash the softener. Therefore, the water supply discharge portion 57 is preferably provided in the vicinity of the discharge port 56 and at a position lower than the second partition wall 36.

Another example of the optimum position of the water supply discharge unit 57 will be described. It is preferable that the water supply discharge portion 57 is provided at a position higher than the discharge port 56. Thereby, the water discharged from the water supply discharge unit 57 can be reliably flowed to the discharge port 56, and the curing of the lotion or the softener of the discharge port 56 can be suppressed, and the reliability can be improved. Further, the water discharged from the water supply discharge unit 57 may be sprayed. To. Thereby, the curing of the lotion or the softener of the discharge port 56 can be suppressed, and the reliability can be improved.

In addition, since the water supply discharge unit 57 is connected to the second water supply pipe 40, water is supplied to the second water supply pipe 40, and the water discharged from the water supply discharge unit 57 is discharged toward the discharge port 56, so that the discharge port can be more suppressed. The curing of 56 lotions or softeners. Further, since the dedicated water supply path for cleaning the discharge port 56 is unnecessary, the water-saving property is improved.

<gear pump height>

In the present embodiment, when the residual amount of the lotion or the softener is small, the lotion or softener is attracted by the negative pressure from the suction port 48 near the bottom surface of each of the tubs 32, 33 to the gear pump 51 portion. . If the height of the attraction is large, since it is difficult to attract the lotion or the softener, the height of the gear pump 51 is preferably close to the bottom surface. On the other hand, in the configuration in which the height of the gear pump 51 is close to the bottom surface, the volume of the lotion or the softener is reduced because the volume of the pump casing 49 sinking into the lotion or the softener is reduced. Here, by providing the gear pump 51 at a height near the middle of the tank bottom surface 46 and the tub lid portion 44, the height from the suction port 48 to the gear pump 51 provided near the bottom surface of the pump casing 49 can be reduced. And it is optimal because it can ensure the capacity of the lotion or softener.

Further, when the height of the gear pump 51 is set to be lower than the liquid level when the lotion tank 32 or the softener tank 33 is replenished with the lotion or the softener, when the lotion or the softener is replenished, The gear pump 51 is in a state of being immersed in a lotion or a softener, that is, a state of "starting water". That is, since it is not necessary to suck the lotion or the softener to the height of the gear pump 51 by the negative pressure of the air, it is possible to reliably supply the lotion or the softener.

When the gear pump 51 is provided close to the bottom surface of the tubs 32 and 33, since the liquid level of the lotion or the softener is always higher than that of the gear pump 51, it is possible to reliably supply the lotion or the softener.

<Filter construction>

In the present embodiment, a filter 58 that enlarges the lower end of the suction port 48 close to the bottom surface of the tubs 32, 33 is provided. The filter 58 is, for example, in the shape of a disk, and a slit 59 having a width of, for example, about 0.5 mm is provided thereon. Since the filter 58 is disposed close to the bottom surface 46 of the tub 32, 33, the lotion in the lotion inlet 25 reaches the suction port 48 provided at a substantially central portion of the filter 58 by slitting. The gear pump 51 is attracted. Because of this configuration, since the foreign matter is mixed into the lotion or the softener, since it can be trapped by the slit 59 of the filter 58, foreign matter does not enter the gear pump 51 through the suction pipe 50 from the suction port 48, so It is possible to provide a highly reliable washing treatment liquid automatic input means 30 by preventing foreign matter from being clogged in the gear pump portion.

<pump drive unit>

A configuration in which the drive gear 51a is driven will be described. As shown in Fig. 7 or Fig. 8, the pump drive shaft 60 is rotatably supported by the pump casing 49 and the pump cover 53, and the drive gear 51a is fixed to the lower end of the pump drive shaft 60, and the pump The upper end of the drive shaft 60 is more protruded than the upper surface of the pump casing 49, and the coupler 61 is fixedly rotatable integrally with the pump drive shaft 60. The coupler 61 is configured to transmit a rotational driving force from a driving means 62 provided in a tub body 31 to be described later.

That is, when the coupling 61 is rotated by the driving means 62, the gear pump 51 is rotated via the pump drive shaft 60, and the detergent in the detergent tank 32 is sucked from the suction port 48 by the action of the gear pump 51. The gear pump 51 and the supply pipe 54 are configured to be sent out from the discharge port 56. The lotion that is sent out from the discharge port 56 is supplied to the input area 39 of the tank storage container 34.

<coupler>

The coupler 61 is formed into an approximately cylindrical shape having a conical shape having a tapered tip end. In the plural of the outer circumference of the coupler 61, in the present embodiment, at three places of every 120 degrees, a coupler protrusion 63 which is convex toward the outer circumference side is provided. In the upper portion of the coupler 61, in the conical portion where the tip end is thin, the coupler protrusion 63 also follows the conical surface to become a thinner tip end of the finer shape.

<cover body, driving means>

The tank lid body 31 is rotatably supported around the support shaft hole 42 provided in the lid body support portion 43. The supply drum 65 of the drive means 62 is provided inside the tank lid body 31. The deceleration means 66 having the gear train and the meshing with the coupler 61 communicate the driving force to the coupler 61 The connector accepts 64. The driving force generated by the supply motor 65 is rotated by a deceleration means 66 composed of, for example, a worm 67 and a reduction gear train including a plurality of spur gears, to a suitable rotational speed, and the coupling receiving portion 64 is rotated. The coupler receiving portion 64 is provided in a type 2, and when the tank lid body 31 is closed, the coupler 61 (the lotion supply coupling) provided in the lottery tank 32 is separately provided, and the softener tank is provided. The coupling 61 (softener supply coupling) of 33 is disposed in meshing engagement. Since the coupler 61 and the coupler protrusion 63 are formed into a finer tip end and a thinner shape, the coupler receiving portion 64 is fitted to the coupler 61 by closing the tub body 31 without being in contact with each other. The contact is stuck and can be smoothly fitted.

<coupler receiving part>

The inner circumference of the coupling receiving portion 64 is a cylindrical recess 68 having a diameter larger than the outer circumference of the coupling protrusion 63 provided on the outer circumference of the coupling 61, and is disposed convex toward the center on the inner circumferential side of the cylindrical recess 68. The protrusions 69 are engaged. In the present embodiment, the engaging projections 69 are disposed at a total of six places every 60 degrees, and the inner peripheral diameter of the engaging projections 69 is larger than the diameter of the coupling 61.

That is, the dimensional relationship of the coupler 61 can be fitted inside the coupler receiving portion 64, and the coupler protrusion 63 is coupled between the adjacent engaging projections 69 disposed in the coupler receiving portion 64. The protrusions 63 and the engagement protrusions 69 do not interfere with each other.

<coupler engagement>

Fig. 10 is a DD sectional view showing a state in which the coupling 61 is fitted inside the coupling receiving portion 64, showing that the coupling receiving portion 64 is rotated counterclockwise in the drawing, and the engaging projection 69 is formed by the coupling protrusion 63. The driving force is transmitted from the coupling receiving portion 64 toward the coupling 61 to a state in which the coupling 61 is rotationally driven.

The coupler 61 and the coupler receiving portion 64 are detachable from each other, and the driving force connecting means 29 that can transmit the rotational driving force can be coupled to each other.

A coupler protrusion 63 is provided at every 3° of every 120° of the outer circumference of the coupler 61, and a total of 6 engagement protrusions 69 are provided every 60° in the inner circumference of the coupler receiving portion 64. With regard to the number of the coupling projections 63 provided on the outer circumference of the coupling 61, by providing the number of engagement projections 69 of the number twice in the inner circumference of the coupling receiving portion 64, since the coupling protrusions 63 can be disposed adjacent to each other The engagement between the engagement projections 69 is such that the engagement of the coupler 61 and the coupler receiving portion 64 is indeed optimal.

When the tub body 31 is closed and the coupler 61 and the coupler receiving portion 64 are fitted and then energized toward the supply motor 65 to rotate the coupler receiving portion 64, the engaging projection 69 is in contact with the coupler projection 63 until as shown in FIG. The coupler receiving portion 64 is idling until the state is rotated, and the rear coupler 61 is rotated together with the coupler receiving portion 64. The maximum value of this idling angle is Φ in Fig. 10, and in the present embodiment, only the angle of the engaging projection 69 and the coupling projection 63 is smaller than the angle of the adjacent engaging projection 69, that is, 60 degrees. The angle of the thickness. When the angle Φ is to close the tank lid 31, even if the supply motor 65 is energized, the gear pump 51 is located. The angle of the non-rotating angle becomes the error in the supply amount of the lotion or the softener, but the angle is at most 60° or less, and the ratio of the error in the supply amount of the lotion or the softener used in the one-time washing process is as small as Will become a problem.

According to the above configuration, the feed pump 65 is rotationally driven in a state where the openable and closed tank lid 31 is closed, and the gear pump 51 is rotationally driven through the coupler receiving portion 64 and the coupler 61. The lotion in the tubs 32 and 33 is supplied to the input field 39 provided in the tub storage container 34.

In the present embodiment, the tub cover 31 including the driving means 62 is rotatably supported above the rinsing tank 32 and the softener tank 33 around the fulcrum 90. By rotating the tub body 31 around the fulcrum, the coupler 61 and the coupler receiving portion 64 are separated, and the upper surfaces of the detergent tank 32 and the softener tank 33 can be opened. Therefore, it is not necessary to move the lottery tank 32 and the softener tank 33 in order to separate the connection of the drive train, because the detergent tank 32 and the softener tank 33 can be moved as long as the tank lid 31 is opened. The top is removed, so the lotion and softener are added and the tank is easy to clean.

<Cover hinge wiring>

The tank lid body 31 is openable and closable, and is provided with wiring 87 from a drive circuit 154 provided in the washing machine body 4 to a supply motor 65. The path through which the wiring 87 is inserted from the washing machine body 4 to the inside of the tub lid 31 is to pass the wiring 87 through the opening and closing center of the tub lid 31, that is, the pivot hole. 42 best. Even if the tank lid body 31 is opened and closed, the wiring 87 is not stretched only by the twisting of the opening and closing angle range, so that the reliability of the wiring 87 is ensured, and a highly reliable washing machine can be provided.

<Cap body size and tank loading and unloading>

The opening size when the tank lid body 31 is opened is larger than the size in which the detergent tank 32 and the softener tank 33 are juxtaposed from the above, that is, the opening when the tank lid body 31 is opened can be made. The size of the detergent tank 32 and the softener tank 33 are removed and installed.

Because of the above configuration, when the tank lid body 31 is opened, the driving force connecting means 29, that is, the coupler 61 and the coupler receiving portion 64 are separated from each other, and the lottery lid body 31 is opened from the open opening. The tank 32 and the softener tank 33 are pulled upward, and the detergent tank 32 and the softener tank 33 can be easily removed.

Conversely, the lottery tank 32 and the softener tank 33 can be easily installed from above by opening the slot lid 31.

Thereafter, when the tank lid body 31 is closed, the coupler receiving portion 64 and the coupler 61 are fitted, and the driving force from the supply motor 65 can be transmitted to the pump means 47 to drive the gear pump 51, and the lotion or softener can be used. The detergent tank 32 or the softener tank 33 is supplied into the water tank 17 via the first detergent supply pipe 14.

<Quantitative supply>

As is known, the gear pump 51 is a metering pump, and the supply amount of the fluid is the tooth The number of rotations of the wheel is proportional. In other words, when the amount of the lotion is supplied to a predetermined amount, for example, the rotation speed of the supply motor 65 is determined by the voltage applied to the supply motor 65, and the drive time of the supply motor 65 is adjusted to a predetermined time. When the number of rotations becomes a predetermined value, the desired amount of the lotion can be supplied.

One of the supply motors 65 is a DC motor, and by setting the applied voltage to the supply motor 65 constant, the rotation speed can be made constant at a predetermined speed. Alternatively, the supply motor 65 is a stepping motor, and the rotation speed may be constant at a predetermined speed by setting the frequency of the pulse applied to the supply motor 65 to be constant.

<Switch action>

Next, an example of a configuration for switching the supply of the lotion and the supply of the softener will be described using FIG. 11 and FIG. 11 and 12 are plan views showing the automatic washing means 30 for washing the washing liquid, and are shown in the tank lid body as seen from the tank lid body 31 to the lottery tank 32 and the softener tank 33. An example of the configuration of the drive means 62 of 31. In the present embodiment, since the washing agent and the softening agent can be selectively supplied by inverting the rotation direction of the supply motor 65 in the forward direction and the reverse direction, the configuration and operation will be described.

<Needle supply>

Fig. 11 is a view showing a state in which the supply motor 65 is operated in the normal rotation direction to supply the lotion, and Fig. 12 is a view showing that the supply motor 65 is moved in the reverse direction. The state in which the softener is supplied.

In the eleventh diagram, the worm 67 is a rotating shaft provided in the supply motor 65, and the worm wheel 70 rotatably supported is engaged with the worm 67, and the rotation of the supply motor 65 is decelerated and transmitted to the worm wheel 70. In the first reduction gear 71 disposed coaxially with the worm wheel 70, the rotatably rotatable central shaft 77 is a second gear that is movably supported along the oscillating groove 72, that is, the oscillating gear 73 is engaged at the first meshing 74a. The swing gear 73 has a rotation center which is located at one end of the first pump drive gear 75 close to the swing groove 72, and meshes with the first pump drive gear 75. As shown in Fig. 8, the first pump drive gear 75 is configured to rotate integrally with the coupler receiving portion 64. In Fig. 11, the worm wheel 70, the swing gear 73, and the first pump drive gear 75 are oriented in the direction of the arrow. The pumping means 47, which is provided in the lottery tank 32, is rotated to supply the lotion to the input field 39.

<Softener supply>

In Fig. 12, the swing gear 73 has a center of rotation which is located at the other end of the swing groove 72 and meshes with the third reduction gear 78. The third reduction gear 78 is further meshed with the second pump drive gear 76. The second pump drive gear 76 is configured to rotate integrally with the coupler receiving portion 64 in the same manner as the first pump drive gear 75. In FIG. 12, the worm wheel 70, the swing gear 73, the third reduction gear 78, and the second pump drive gear 76 is driven by the pump means 47 provided in the softener tank 33 in the direction of the arrow in the figure, and the softener is supplied to the input field 39.

<Motor is reverse switching>

Here, at the time of the forward rotation shown in FIG. 11, the swing gear 73 receives and rotates the force in the substantially tangential direction from the first reduction gear 71 in the first engagement 74a toward the rotational driving direction, along the swing groove. The 72 is moved to rotate in engagement with the first pump drive gear 75 by the second engagement 74b. When the supply motor 65 is reversed from this state, since the first reduction gear 71 also rotates in the reverse direction, the swing gear 73 receives the force in the substantially tangential direction in the reverse direction from the first reduction gear 71, and follows the reverse groove along the reverse rotation. The movement from the one end toward the other end causes the engagement with the first pump drive gear 75, that is, the second engagement 74b to fall off, and on the other hand, the third reduction gear 78 is engaged by the fourth engagement 75d. Since the swing gear 73 moves along the swing groove 72, the engagement with the first reduction gear 71 is moved toward the third mesh 74c. When the supply motor 65 is reversed, the state of FIG. 11 is moved to the state of FIG. 12 to rotate in the direction of the arrow, and the second pump drive gear 76 is rotationally driven to supply the softener from the softener tank 33.

When the supply motor 65 is rotated forward in the state of Fig. 12, since the first reduction gear 71 also rotates in the forward direction, the swing gear 73 receives a force in a substantially tangential direction from the first reduction gear 71 in the positive direction, so The rotation in the rotational direction moves along the swing groove 72 from the other end toward the one end, the meshing with the third reduction gear 78 is released, and the first pump drive gear 75 rotates in meshing engagement. In other words, when the supply motor 65 is rotated forward, the washing agent is supplied from the detergent tank 32 from the state of Fig. 12 to the eleventh diagram.

Here, the distance between one end and the other end of the swing groove 72 is When the swing gear 73 and the first pump drive gear 75 are engaged, the swing gear 73 and the third reduction gear 78 are separated without meshing, and when the swing gear 73 and the third reduction gear 78 are engaged, the swing gear 73 and the first pump drive The gear 75 may be separated and not engaged, and such a condition can be obtained when the distance of the gear is substantially greater than the height of the teeth.

<Swing gear meshing>

Since the swing gear 73 is moved toward the other end of the swing groove 72, the meshing position of the swing gear 73 and the first reduction gear 71 is moved from the first mesh 74a toward the third mesh 74c. Needless to say, since the swing gear 73 has a small distance between one end and the other end of the swing groove 72, the distance between the first mesh 74a and the third mesh 74c is small, and the meshing state of the swing gear 73 and the first reduction gear 71 does not deteriorate.

Further, a straight line connecting the midpoint of one end and the other end of the swing groove 72 and the center of rotation of the worm wheel 70 is arranged perpendicularly to a line connecting one end and the other end of the swing groove 72, along the swing groove 72. Since the moving direction of the oscillating gear 73 is the tangential direction in which the oscillating gear 73 and the worm wheel 70 mesh, the oscillating gear 73 moves evenly, and the change in the distance between the center of the oscillating gear 73 and the first reduction gear 71 is almost no, so further optimal.

<The pump is rotating in the same direction>

In the forward rotation state of Fig. 11, since the first pump drive gear 75 provided with the coupler 61 is rotated in meshing engagement with the swing gear 73, it is provided in the lotion The pump drive shaft 60 of the tub 32 is rotated in the opposite direction to the swing gear 73.

On the other hand, in the reverse state of Fig. 12, the second pump drive gear 76 including the coupler 61 is driven by the pump of the softener tank 33 because it is rotated from the swing gear 73 through the third reduction gear 78. The shaft 60 is rotated in the same direction as the swing gear 73. In the forward rotation state and the reverse rotation state, since the rotation directions of the swing gears are opposite to each other, the first pump drive gear 75 and the second pump drive gear 76 rotate in the same direction. In other words, the pump means 47 for supplying the lotion and the pump means 47 for supplying the softener may be configured to supply a lotion or a softener when rotating in the same direction, and may have the same configuration, and the parts may be common. The advantage that can be made cheaply.

<Summary of positive reversal switching action>

According to the present embodiment, when the supply motor 65 is rotated forward, only the pump means 47 provided in the detergent tank 32 is driven to supply the lotion, and when the supply motor 65 is reversed, since only the pump to be provided in the softener tank 33 can be used. Since the softener is driven by the means 47, the supply of the lotion and the softener can be selected by only the single supply motor 65, and the automatic washing means 30 for the washing process can be realized with a simple structure and a low price.

Further, the forward rotation and the reverse rotation are merely for convenience in explaining the user of the embodiment, and are not limited to such performance.

<residual detection>

Figs. 13 and 14 are schematic views showing an example of the configuration of the residual amount detecting means 79 of the washing treatment liquid in the present embodiment.

A light-emitting element 80 such as an LED is provided on one surface of the detergent tank 32, and the light-receiving element 8 is provided coaxially with the light-emitting element 80 on the facing side of the light-emitting element 80 of the detergent tank 32. The light receiving element 81 is an element that converts the intensity of light into an electrical signal, such as a phototube or a photodiode.

Since the tanks 32 and 33 are formed of a transparent resin, when the washing treatment liquid does not enter, the light from the light-emitting element 80 passes through the tubs 32 and 33 and reaches the light-receiving element 81, so that an electric signal is generated in the light-receiving element 81. On the other hand, when the washing treatment liquid is put into the tubs 32 and 33, since it is shielded from light, no electrical signal is generated in the light receiving element 81. Here, by arranging the pair of the light-emitting element 80 and the light-receiving element 81 at a predetermined height from the bottom surface of the tubs 32 and 33, the height of the liquid level of the washing treatment liquid in the tubs 32 and 33 can be checked. Out.

As shown in Fig. 14, the pair of the light-emitting element 80 and the light-receiving element 81 are provided at two heights h1 from the bottom surface 46 of the tubs 32, 33, which are close to the bottom surface 46, and two heights h2 above h1. .

When the washing treatment liquid is sufficient in the tank and the liquid level is higher than h2, the first light-receiving element 81 and the second light-receiving element 81 are shielded from light, so that the liquid level is higher than h2. high.

The liquid level of the washing treatment liquid is H1 between h1 and h2 because the first light receiving element 81 provided at the position of the height h1 is covered. Light, the second light receiving element 81 provided at the position of the height h2 is received by light and generates an electrical signal, so that the liquid level H1 is located between h1 and h2.

When the liquid level of the washing treatment liquid is lower than the height h1, since the first light receiving element 81 and the second light receiving element 81 receive light from the light emitting element 80 to cause an electrical signal, it is known that the liquid level is Near the bottom surface, the residual amount of the washing treatment liquid is almost absent.

When the liquid level of the washing treatment liquid is H1, the first light receiving element 81 is shielded from light, and the second light receiving element 81 receives light and generates an electrical signal. In the case where the washing treatment liquid is translucent, the first light receiving element 81 is not completely shielded from light, but since the amount of light is lowered, the electrical signal generated is reduced. Here, when the difference between the electric signal generated by the second light receiving element 81 is measured, it can be more reliably determined than the increase or decrease of the signal of only the single light receiving element: the liquid surface is located at the first light receiving element 81 and the second light receiving element. Between elements 81.

Here, when the liquid level of the washing treatment liquid is H1, the residual amount of the washing treatment liquid is set to, for example, 2-3 times, and the heights of h1 and h2 are set, and the washing liquid to be notified at this time is provided. If the amount is a notification means for the micro-use, the user can know the time point of replenishing the washing treatment liquid, so that the user does not notice that the lotion is used up, and the washing liquid having high reliability can be automatically input. Means of washing machine.

<slot bucket removal>

According to this embodiment, there is no provision in the tanks 32, 33 for example A wiring connection portion for detaching the body such as a wiring for driving the motor 65.

In other words, the driving force for driving the gear pump 51 from the supply motor 65 is driven by the driving means 62, that is, the coupling means 61 drives the pump means 47 from the driving means 62 provided on the main body of the washing machine. Further, the detecting means for detecting the residual amount of the washing treatment liquid in the tanks 32, 33, that is, the light-emitting element 80 and the light-receiving element 81 are provided on the washing machine main body 4 side. Therefore, when the user removes the tubs 32, 33 for supplying the washing treatment liquid, as shown in Fig. 1, the tub lid 31 in which the driving means 62 is built is opened, because the coupler 61 is coupled. Since the container receiving portion 64 is separated, the tubs 32 and 33 can be easily removed together with the pump means 47 when the state in which the tub handle 44a is gripped is pulled upward.

<Needing agent dripping prevention>

Here, since the tubs 32 and 33 and the pump means 47 are integrally removed, when the tubs 32 and 33 are taken out from the washing machine body, the washing liquid is not dripped, which is preferable.

<effect>

<Automatic supply of washing treatment liquid>

As described above, the lotion and the softener which are filled in the respective tubs can be automatically supplied only at a predetermined time point in the washing process or the washing process. Further equipped with measuring means, supply pair If the amount of the cloth to be measured is controlled, since the lotion and the softener are not used too much or insufficient, it is possible to provide a washing machine without unnecessary waste of the lotion and the softener.

<Positive reversal switching action>

The rotation direction is switched by turning the supply motor 65 forward and reverse, because the gear pump provided in the detergent tank 32 is driven to supply the lotion during forward rotation, and the gear set in the softener tank 33 when reversed. Since the pump is driven to supply the softener, since the two gear pumps can be selectively driven by only one motor, the drive system can be configured inexpensively.

<residual detection>

Since the residual amount detection means is provided, the residual amount in the tank of the lotion or the softener is detected, and when the residual amount is less than the predetermined amount, since it can be notified to the user, it is possible to provide a lotion prevention and softness. A washing machine with high reliability and low reliability.

<Cap body size and tank loading and unloading>

The lid body is provided with a driving means including a motor and a reduction gear, and when the lid body is closed, the driving force connecting means 29 provided in the driving means and the pump portion is connected to transmit the driving force of the motor to the gear pump 51, and the lid body is attached. When the opening is performed, the coupler receiving portion 64 of the driving force connecting means 29 and the coupler 61 are separated. When the opening size of the tank lid body 31 is larger than the size of the lottery tank 32 and the softener tank 33 from a plan view, the lotion tank It is easy to remove and install the tub 32 and the softener tank 33.

<coupler reliability>

The driving force connecting means 29 is provided between the lower surface of the tub cover 31 on the upper surface of the washing machine main body 4 and the upper surfaces of the tubs 32, 33. That is, the height of the driving force connecting means 29 in the tubs 32, 33 is higher than the level of the liquid even if the lotion or the softener is fully filled. Therefore, even if the lotion or softener leaks from the tubs 32, 33, the liquid level does not reach the driving force connecting means 29, or the driving means 62 provided in the tub lid 31, and the lotion or softener does not The drive means 62 will be invaded.

Further, since the coupler receiving portion 64 that is rotationally driven among the driving force connecting means 29 is provided on the lower surface of the tub cover 31, when the tub lid 31 is opened, it is more than the upper surface of the washing machine body 4. The high position is a configuration that becomes an almost vertical opening.

When the user removes the lottery or softener into the tanks 32, 33 and the tanks 32, 33 are taken in, the lotion or softener is dripped until the lotion or softener is on the top of the washing machine body 4, or The interior of the tank storage container 34. Since the inside of the tub storage container 34 is not provided with, for example, a rotation driving portion of the coupler receiving portion 64, the dripping lotion can provide a highly reliable washing machine because it does not intrude into the driving portion of the rotary driving portion.

<No slotted wiring>

The wiring to the supply motor 65 for driving the pump means 47 is from the laundry The machine body 4 is disposed inside the tub body 31, and there is no wiring to the supply motor 65 in the tubs 32, 33. Further, the residual amount detecting means 79 of the tanks 32, 33 is also disposed outside the tank, and the wiring of the residual amount detecting means 79 is also disposed in the washing machine body 4.

Therefore, since the electrical tank parts are not disposed in the tanks 32 and 33, when the tanks 32 and 33 are attached or detached, since the wiring connection means such as the power contact having the connector is not required, the lotion is not used. It is possible to provide a highly reliable washing machine by attaching to a power contact or the like and causing contact failure.

<slot cleaning performance>

Since the tubs 32 and 33 are easy to remove and have no wiring and power contacts, the entire tubs 32 and 33 may be immersed in water. Therefore, it is easy to wash away the lotion and the softener remaining inside the tanks 32, 33, and the tank can be kept clean. When the lotion or the softener is replenished, the washing performance is deteriorated by mixing with the old lotion and the softener adhering to the inside of the tubs 32 and 33, so that a highly reliable washing machine can be provided.

<pump cleaning>

Since the pump means 47 is provided with the driving force connecting means 29 connectable and detachable from the driving means 62, the tub and the pump means 47 can be detachably removed, and in the tank and the pump means 47, the pump is not provided. Means 47 drives the wiring for the power, because further can be not detected with the wash Since the structure of the wiring to which the detection means of the residual amount of the agent or the softener is connected is easy to remove, the inside of the tank and the inside of the pump are also washable, and it is possible to provide a washing machine with improved cleaning performance and reliability.

Since the pump means 47 can be removed from the tub body 45, the suction port of the pump means 47 is immersed in water, and the coupler 61 is rotated by the hand, since water is sucked from the suction port 48 and passed through the inside of the gear pump 51. Since the discharge port 56 is discharged, the inside of the pump means 47 can be washed with water. Therefore, it is possible to prevent the old lotion and the softener from deteriorating to block the pump, or to replenish the lotion or the softener, since it is not mixed with the old lotion and softener attached to the inside of the pump means 47. Since the net performance is degraded, it is possible to provide a highly reliable washing machine.

Further, when the shell of the pump means 47 is molded of a transparent resin, it is visually confirmed that the lotion and the softener remain in the pump, or the cleaning is completed, which is preferable.

<gear pump height>

The arrangement height of the gear pump 51 is disposed at a position lower than the liquid level when the tanks 32 and 33 are used to replenish the lotion or the softener, and the gear pump 51 is immersed when the lotion or the softener is replenished. The state of the lotion or softener is the state of "starting water". That is, since it is not necessary to suck the lotion or the softener to the height of the gear pump 51 by the negative pressure of the air, the lotion or the softener can be reliably supplied, and a highly reliable washing machine can be provided.

<Compatible with manual supply>

When the user's preference is to be washed by the lotion in the lottery tank 32, and/or the other lotion that has been put into the lotion inlet 25, since it can be used separately, it can be used. A washing machine having a washing liquid automatic charging means 30 is provided with good convenience.

<Filter construction>

Since the filter 58 provided with the slit 59 is provided in the periphery of the suction port 48 of the pump means 47, it is possible to prevent foreign matter from being sucked and to block the gear pump 51, and it is possible to provide the washing process liquid automatic input means 30 which is highly reliable. effect.

In the present embodiment, the two pumps are selectively driven in response to the forward reversal of one motor. However, each of the slots is provided with a motor and a deceleration means, and different motors are selectively driven to selectively supply the lotion and the softener. The composition can also be.

In the present embodiment, the pump is a gear pump, but is not limited to a gear pump, a pump such as a piston pump, a diaphragm pump, or a wing pump.

In the configuration disclosed in Patent Document 1, since the transport pump is a structure in which the DC motor and the gear pump are provided inside and immersed in the liquid, there is an upper limit to the miniaturization of the transport pump. When a reduction gear is provided between the DC motor and the gear pump in order to adjust the rotation speed of the gear pump, the reduction gear must also be provided inside the conveyance pump. Because the handling pump is placed in the lotion tank, there is a limit in the size of the motor The reduction ratio of the size and reduction gear has an upper limit. On the other hand, in the above embodiment, since the driving force connecting means 29 that can transmit and separate the rotational driving force transmitted from the driving means 62 to the pump means 47 is provided, the above problem can be eliminated.

Further, although the above embodiment has described an example of a drum type washing machine, the present invention is not limited thereto and can be applied to a vertical type washing machine.

[Seventh embodiment]

The seventh embodiment will be described using Figs. 25 to 37.

The seventh embodiment differs from the first embodiment in that the detergent tank 32 and the softener tank 33 are not placed side by side but are juxtaposed to each other, and the detergent tank 32 is further brought to the left of the softener tank 33. Further, the left side of the washing machine body 4 is disposed, and the capacity of the detergent tank 32 is larger than the capacity of the softener tank 33. Further, the injection area 39 of the lotion or the softener which is picked up by the pump from the detergent tank 32 and the softener tank 33 is disposed on the rear side of the tank storage container 34, and is placed in the tank storage. The container 34 and the water supply means 93 having the water supply tap 7 and the water supply solenoid valve 12 are provided.

Therefore, since the input field 39 is disposed close to the water supply means 93, there is an advantage that the second water supply pipe 40 that supplies water from the water supply means 93 to the input field 39 is short.

Further, a third detergent supply pipe 118 having one end connected to the opening of the bottom surface of the tub storage container 34 and the other end connected to the first lotion supply tube 14 is provided. The lotion or softener that has overflowed into the interior of the tank storage container 34 is introduced into the water tank 17 via the third detergent supply pipe 118 and the first detergent supply pipe 14.

A fixed support frame 94 made of, for example, an iron plate is provided which fixes the left and right ends to the upper surface of the left outer frame 2 and the right outer frame 2 and connects the left and right outer frames 2 to each other, and is washed in the rear side of the fixed support frame 94. The front side of the tank storage container 34 of the treatment liquid automatic input means 30 is fixed by the attachment bolt 116, and the rear side of the lotion insertion opening 25 in the front side of the fixed support frame 94 is not shown. Bolts, etc. are fixed.

A first water supply pipe 9 that connects the water supply solenoid valve 12 and the lotion supply port 25 is disposed along the right side surface of the tank storage container 34. One side or a plurality of barrel side guides 95 protruding from the right side surface of the tank storage container 34 are formed, and the plurality of tank side guides 95 are spaced apart from each other by a distance slightly smaller than the diameter of the first water supply pipe 9 When a water supply pipe 9 is pressed in, the first water supply pipe 9 can be fixed by the side guide 95 of the tank.

Further, as shown in Fig. 30, the first water supply pipe 9 is disposed from the right to the left along the front side of the tub storage container 34, and is connected to the lotion input port 25.

Since the tank storage container 34 and the lotion supply port 25 are fixed to the common fixed support frame 94 in this manner, it is not necessary to provide individual fixing members, and the arrangement relationship between the two is not caused by the operation. Since it moves or deviates from the vibration and impact during transportation, it is possible to provide a washing machine having a high reliability and reliability of the first water supply pipe 9.

Further, in the seventh embodiment, the first embodiment differs from the first embodiment in that, in the first embodiment, only one supply motor 65 is provided, and when the supply motor 65 is rotated forward, the detergent tank 32 is transmitted through the swing gear 73. Inside In the case where the supply motor 65 is reversed, the softener in the softener tank 33 is supplied to the input field 39 through the swing gear 73. However, in the seventh embodiment, for example, As shown in the figure, the respective pump means 47 provided in the detergent tank 32 and the softener tank 33 are provided with separate portions of the separate detergent supply motor 65a and the softener supply motor 65b.

A worm 67 is provided in each of the shafts of the lotion supply motor 65a and the softener supply motor 65b, and a worm wheel 70 is provided in the coupler receiving portion 64 to mesh with the worm 67, and the lotion supply motor 65a and the softener supply motor 65b are provided. When rotated, the worm wheel 70 rotates in a decelerated manner, and the coupling receiving portion 64 is rotationally driven. The worm 67 and the worm wheel 70 are configured by the deceleration means 66 in the present embodiment.

When the detergent supply motor 65a is driven in the normal rotation direction, the pump means 47 in the detergent tank 32 is driven to supply the detergent in the detergent tank 32 to a predetermined amount in the input field 39, and the softener is supplied to the motor. When the 65b is driven in the normal rotation direction, the pump means 47 in the softener tank 33 is driven to supply the detergent in the softener tank 33 to a predetermined amount in the input field 39.

Here, since the amount of the lotion or the softener remaining in the pump means 47 is different after the supply of the lotion or the softening agent is stopped, there is a problem that the supply amount error occurs due to the difference.

Further, when the lotion or the softener is replenished, or when the tubs 32 and 33 are removed for cleaning, since the driving means 62 is opened rearward together with the tub lid 31, the driving is opened. hand The connector receiving portion 64 that conveys the driving force toward the pump means 47 in the front surface of the segment 62 is exposed. When the lotion or the softener adheres to the coupler receiving portion 64, there is a problem that the gap between the outer periphery of the coupler receiving portion 64 is intruded or adhered to the inside of the driving means 62, and the transmission of the driving force is hindered.

An example of the structure of the lottery tank 32 and the softener tank 33 will be described using Figs. 31 and 32, and suitable Figs. 25 to 30.

The difference from the first embodiment shown in Fig. 6 or Fig. 7 is that the pump casing 49 is integrated with the tub cover portion 44 and extends toward the bottom surface 46 of the tub, and is fitted to the tub body 45. On the open top, the upper cover is constructed. The knob-shaped convex portion, that is, the grooved lid open handle 96 is provided on a portion of the upper surface of the tub cover portion 44. When the tub lid portion 44 is removed from the tub body 45, the finger can be hooked, so that it can be easily The tub cover portion 44 is removed.

The tub handle 44a is rotatably supported around the handle fulcrum 97 of the tub body 45, and is housed in the tub storage container 34 when the tub handle 44a is located substantially above the tub lid portion 44. The same height and substantially horizontal storage position, which rotates the tub handle 44a around the handle fulcrum 97, can be located at a substantially vertical tank loading and unloading position illustrated by the dashed line in FIG. Since the tank handle 44a is located at the storage position, it is possible to suppress the overall height of the detergent tank 32 or the softener tank 33 including the tank handle 44a, so that it is suitable for downsizing. When the tank handle 44a is located at the tank loading and unloading position, the detergent tank 32 or the softener tank 33 can be removed from the tank by pulling the tank handle 44a upward. The barrel storage container 34 is removed, and is easily detachable.

Since the handle fulcrum 97 is provided in the tub body 45, the tub body 45 does not fall or fall when the tub handle 44a is lifted, and can be stably removed.

Further, an openable and closable supply cover 99 rotatably supported around the supply cover support shaft 98 is provided in the tub cover portion 44, and a lotion or softener can be applied from the opening when the supply cover 99 is opened. It is supplied into the tanks 32, 33. When the residual amount of the liquid lotion or softener in the tanks 32, 33 is reduced, the tanks 32, 33 are not removed, only the supply lid 99 is opened, and the liquid lotion or softener can be replenished. Alternatively, the supply cap 99 may be opened to replenish the tanks 32 and 33 from the tank storage container 34 to replenish the liquid detergent or the softener.

A recessed portion, that is, a hook portion 100, is provided in a surface farthest from the supply cover shaft 98 of the tub cover portion 44 and the supply cover 99, and the supply cover 99 is easily opened.

After the liquid lotion or softener in the tanks 32, 33 is used up, the inside of the tank is washed by periodically removing the tanks 32, 33, and the residual lotion or softener is washed away by water to prevent it. Attachment and the like are preferred. Further, the liquid detergent or the softener is discharged inside the gear pump 51 and the supply pipe 54, and the inside of the gear pump 51 and the supply pipe 54 is preferably washed with water.

After the tanks 32, 33 are removed, the water is placed in the tanks 32, 33, or the tank lid portion 44 is further removed from the tank body 45, and the suction port 48 at the lower end of the pump means 47 is immersed in water. , by hand, the coupler When the gear 61 rotates, the gear pump 51 sucks water through the supply pipe 54 and discharges it from the discharge port 56. By continuing this operation, water can be supplied to the inside of the gear pump 51 and the supply pipe 54. If the hand is used, the coupler 61 cannot be rotated at a low speed. Therefore, it takes time to wash the water, and since the flow rate of the water is also low, the water washing ability has Upper limit.

In the present embodiment, a pinion gear 101 having a number of teeth of 10 or 12 is disposed below the coupler 61, and the fast-rotation gear 102 meshing with the pinion gear 101 is rotatable around the center of the fast-rotation gear 103. Settings. When the number of teeth of the fast turning gear 102 is set to, for example, 30 to 36, the coupler 61 can be rotated by 3 times the rotational speed of the fast turning gear 102. In the fast turning gear 102, by, for example, a recess or a protrusion which can be hooked by the tip of the finger is provided, since the action of the finger tip can rotate the coupler 61 by the high speed via the fast turning gear 102, a sufficient amount of water can be used. Since the flow rate is also increased in proportion to the rotational speed in the gear pump 51 and the supply pipe 54, it is possible to provide a washing machine which can be washed in a short time and which can prevent clogging of the gear pump 51 and the supply pipe 54, and which has high reliability.

The configuration of the gear pump 51 will be described with reference to Figs. 33 to 35. Fig. 33 is a view showing the configuration of the pump means 47. Unlike the first embodiment, the shape of the pump casing 49 is not a cylindrical shape but a quadrangular prism shape, and does not have the suction pipe 50. The gear pump 51 is close to the bottom surface 46 of the tank. Configuration.

The supply characteristics of the supply motors 65a and 65b, the deceleration means 66, and the gear pump 51 when the lotion and the softener having different viscosities are supplied will be described with reference to Figs. 36 and 37.

Generally, softeners have a viscosity ratio of about 1 mPa ‧ s That is, the water is high, for example, the viscosity at room temperature of about 20 ° C is mostly 20 to 100 mPa ‧ s. The liquid lotion is about 100 to 300 Pa ‧ at room temperature, and the viscosity in the low temperature near the freezing point is also 1000 to 1200 mPa ‧ s, and the viscosity is different from the low viscosity softener to the high viscosity liquid lotion. It is about 60 times.

When the liquid lotion and the softener having different viscosities are automatically supplied, the target supply amount which is the target value of the supply amount differs depending on the product of each liquid lotion and softener, or the amount of dirt of the clothes. The target supply amount of the liquid lotion which is contained in, for example, a standard washing process is different between the concentrated lotion and the non-concentrated lotion, and varies depending on the manufacturer and the product. The target supply amount of the softener is also different for each product.

Here, the supply time until the supply target supply amount is not required to be the same for the softener and the liquid detergent. On the other hand, since the target supply amount is supplied with high precision, the voltage applied to the supply motors 65a and 65b is applied. Under certain conditions, the amount of viscosity per unit time is necessarily better from the gear pump 51 regardless of the magnitude of the viscosity. Since the supply amount per unit time is constant, by controlling the driving time of the gear pump 51, it is possible to supply the lotion or the softener with high precision for the target supply amount.

However, since the characteristics of the gear pump 51 vary depending on the magnitude of the viscosity of the liquid to be transported, the supply amount per unit time does not become constant, and the viscosity can be changed in accordance with the magnitude of the viscosity.

Here, in the viscosity range from the softener having the smallest viscosity to the liquid detergent having the highest viscosity, the difference between the maximum supply amount per unit time and the minimum supply amount is referred to as "the supply amount varies".

Since the viscosity of the softener or the liquid lotion cannot be specified in advance, the preferred characteristics of the pump are in the range from low viscosity to high viscosity, and the "supply amount is different". The optimum conditions of the gear pump 51 having such supply accuracy and the deceleration means 66 for driving the gear pump 51 will be described.

As described above, when the supply motors 65a and 65b are, for example, a DC brush motor having a drive voltage of about 12 V, the gear pump 51 is rotated by deceleration by the deceleration means 66. The supply motors 65a and 65b are, for example, stepping motors or servo motors, and speed-controllable motors are also possible, but these are expensive compared to DC brush motors. When the relationship between the rotational speed of the general DC brush motor and the output torque is described, the rotation speed is changed in accordance with the output torque in a state where a constant driving voltage is applied. That is, the maximum rotational speed is obtained when the output torque is zero idling, and becomes lower as the output torque increases, and the maximum output torque is generated when the rotational speed becomes zero and stops. That is, the rotational speed is a characteristic that linearly decreases in response to an increase in the load torque.

When the gear pump 51 is rotationally driven to supply the lotion or the softener by the DC brush motor having such a characteristic, if the load torque generated by the gear pump 51 is constant, the supply motors 65a and 65b are rotated by the corresponding load torque. Speed rotation. However, when the viscosity of the supplied liquid detergent or softener is different, the rotational speed of the supply motors 65a and 65b changes because the viscosity resistance or the like is different.

The supply characteristics of the gear pump 51 will be described using Figs. 34 to 37.

As shown in FIGS. 34 and 35, when the gear pump 51 is rotated in the direction of the arrow, the liquid is washed into the gap between the drive gear 51a of the gear pump 51 and the teeth of the driven gear 51b and the gear pump wall 55. The agent or softener rotates together with the drive gear 51a and the driven gear 51b, and is conveyed from the suction port 48 toward the supply pipe 54 or the discharge port 56. On the side of the suction port 48, the liquid detergent or the softener is sucked from the inside of the tubs 32 and 33 at the low pressure, and the liquid detergent or the softener is transported toward the discharge port 56 on the side of the supply tube 54.

Here, in the gear meshing portion 52 of the drive gear 51a and the driven gear 51b, the supply of the high pressure is caused by the side clearance δ occurring between the side faces of the drive gear 51a or the driven gear 51b and the facing wall faces. The tube 54 side flows toward the low pressure suction port 48 side in the direction indicated by the dotted arrow. This flow is a countercurrent flow of the liquid lotion or the softener that is transported from the suction side to the discharge side (hereinafter referred to as "side leakage"), and the amount of this reverse flow is affected by the "different supply amount" . The side leakage is because the liquid is more likely to pass through the side gap δ, so that the viscosity is lower and the tendency is larger.

Needless to say, the smaller the backflow, the smaller the supply amount is, the smaller the side gap δ is, and the higher the cost, the higher the cost.

On the other hand, when the components such as the gear pump 51 and the pump casing 49 are made of a resin, for example, the side gap δ needs to be a gap of about 0.1 mm. The side leakage through the gap tends to be as the viscosity of the liquid becomes lower and the viscosity becomes higher and the density becomes smaller. If the side leaks too much, the result, Since the supply amount discharged from the discharge port 56 is reduced, the "supply amount varies" is increased.

In the case of the side leakage, since the influence of the side gap δ is large, the influence of the rotational speed of the gear pump 51 is small, so that the side gap δ is the same, the gear pump 51 is rotated at a high speed to increase the supply speed and the side of the supply amount is leaked. The smaller the ratio, the smaller the "supply amount varies", and the more the gear pump 51 is reversed from the low-speed rotation supply speed, the greater the influence of the side leakage, and the "supply amount varies".

On the other hand, after the suction port 48 is sucked in, the viscous resistance occurs in the conveyance path of the liquid which is discharged from the discharge port 56 by the supply pipe 54. Needless to say, the viscous resistance is such that the lower the viscosity of the liquid, the smaller the viscosity, and the higher the viscosity. As described above, when the supply motors 65a and 65b are DC brush motors, since the rotation speed has a characteristic that linearly decreases in accordance with an increase in the load torque, the viscosity of the liquid is lower, and the rotation speed of the gear pump 51 is higher. The higher the viscosity, the more the rotation speed tends to decrease. When the rotation speed is lowered, the amount of liquid discharged from the discharge port 56 is reduced, so that the "supply amount varies".

Thus, the backflow caused by the side gap, that is, the side leak, has a tendency that the viscosity of the liquid is as low as possible, and the decrease in the rotational speed caused by the viscous resistance tends to be opposite to each other as the viscosity of the liquid increases.

The influence of the "supply amount of the difference" of the viscosity is further described in detail using the graph of Fig. 36. Figure 36 (a) to (c), This is an explanatory diagram exaggeratingly showing the influence of the side leakage and the rotational speed variation caused by the viscosity η.

The horizontal axis of Fig. 36 (a) to (c) shows the viscosity of the liquid, and one of them is a softener having a small viscosity η at the left end, and the highest viscosity η at the right end is, for example, a liquid lotion until the ice temperature is approached. Cooling situation.

The vertical axis indicates the ratio of the supply amount, and there is no side leakage, and the ideal state in which the rotation speed is not caused by the viscous resistance is set to 100%, and the reduction ratio of the supply amount from there is displayed.

In the 36th (a) to (c), each of the supply motors 65a and 65b is a DC motor having the same output characteristics, and the side clearance δ is the same, and the reduction ratios from the supply motors 65a and 65b to the gear pump 51 are Different. In the figure, the broken line indicates the tendency of the rotation speed due to the viscosity to change, and the one-point lock line indicates the tendency of the supply amount due to the side leakage to decrease. Further, in Figs. 36(a) to (c), since the gears having different reduction ratios have different rotation speeds of the pump 51, the supply amount per unit time is different from each other.

Since the supply amount of the gear pump 51 is the multiplication of the rotation speed reduction characteristic and the side leakage characteristic, as shown by the solid line, the low viscosity liquid on the left end side is dominated by the decrease in the supply amount due to the side leakage. The high-viscosity liquid on the right end side is governed by a decrease in the supply amount due to a decrease in the rotational speed, and the viscosity in the middle tends to have a maximum supply amount. Therefore, the indicator showing the accuracy of the supply amount is the full viscosity range from low viscosity to high viscosity, and the maximum value is taken as the maximum value, which will be When the leakage or the decrease in the rotational speed is the minimum value of the supply amount, the difference between the maximum value and the minimum value is "the supply amount varies". Needless to say, the "supply volume varies" is the smaller the supply accuracy is.

Fig. 36(a) shows a case where the reduction ratio is large, because the output torque is large, so that the rotation speed of the high-gloss liquid gear pump 51 is small, and since the rotation speed is low, the side leakage of the liquid having a low viscosity is changed. Big. Since the rotation speed is low, the supply per unit time is the smallest. "The amount of supply varies" is between the supply of low-viscosity liquid and the maximum value of intermediate viscosity. The characteristics of (a) are not suitable for the supply of a low-viscosity liquid, but are suitable for the supply characteristics of a high-viscosity liquid supply.

Fig. 36 (c) is a case where the reduction ratio is inversely small, because the output torque is small, so that the decrease in the rotational speed of the gear pump 51 for the high-viscosity liquid becomes large, because the rotation speed is high, so for the liquid of low viscosity The side leakage is small. Since the rotation speed is high speed, the supply amount per unit time is the largest. "The amount of supply varies" is between the supply of high-viscosity liquid and the maximum value of intermediate viscosity. The characteristics of (c) are not suitable for the supply of a high viscosity liquid, but are suitable for the supply characteristics of a low viscosity liquid supply.

Fig. 36(b) is the case of the reduction ratio in the middle of (a) and (c), and the effect of the decrease in the rotational speed of the gear pump 51 of the high-viscosity liquid and the side leakage of the low-viscosity liquid is the same. The supply of high-viscosity liquid and the supply of low-viscosity liquid are almost equal, and the "supply amount varies" is the supply of high-viscosity liquid or low-viscosity liquid. The amount of the feed, and the maximum value of the intermediate viscosity occur.

In this case, since the "supply amount is different" can be minimized for the entire range from low viscosity to high viscosity, the supply accuracy can be improved and optimal.

Fig. 37 is an explanatory diagram showing an example of actual measured values in which the horizontal axis represents the reduction ratio and the vertical axis represents the "supply amount varies". The same supply motors 65a and 65b (small DC motors) drive the gear pump 51 through the deceleration means 66 of four different reduction ratios, from the low-viscosity softener to the liquid detergent cooled by the ice temperature. Each of the reduction ratios adopts a viscosity range of about 20 to about 1200 mPa·s, and the "supply amount varies".

The reduction ratio is a low torque in the range of the reduction ratio of 20 or less. For the high viscosity detergent, the torque is insufficient. Therefore, as shown in Fig. 36 (c), the "supply amount" caused by the decrease in the rotation speed can be seen. The increase is mixed.

In the range of the high reduction ratio in which the reduction ratio is 30 or more, although the torque is high, the rotation speed is low, and the low viscosity softener is insufficient in speed. As shown in Fig. 36 (a), the gear pump 51 can be seen. The increase in side leakage increases the "supply volume varies".

On the other hand, in the range where the reduction ratio is 20 to 30, the fluctuations in the side leakage and the rotational speed are canceled each other, and the "supply amount varies" is approximately 10%, and the supply accuracy is ensured irrespective of the viscosity. The combination of the supply motors 65a, 65b and the reduction ratio. Therefore, by supplying the motors 65a, 65b and the deceleration means 66 in this range The combination of the reduction ratio, the supply amount of the high-viscosity liquid, and the supply amount of the low-viscosity liquid are almost equal, and as a result, since the "supply amount varies" is minimized, for example, the viscosity can be about 20 to about 1200 mPa. The softener until s is supplied to the lotion with high precision. In other words, since the supply amount per unit time without depending on the viscosity of the liquid is substantially constant, if the driving time of the supply motors 65a and 65b is controlled, the lotion or the softener having different viscosities are only accurately obtained. The effect of the supply.

Further, the pump for lotion and the pump for softener may have different speed reduction ratios, and the pump for lotion has a characteristic that the deceleration means 66 has a high reduction ratio and a high speed suitable for high-viscosity liquid supply, and high torque. The softener pump may have a characteristic that the deceleration means 66 has a low reduction ratio which is suitable for low-suction liquid supply and has a low torque.

The pump for lotion and the pump for softener may have a configuration in which the side gap δ of the gear pump 51 is different. Since the pump for lotion is less prone to side leakage, the gear pump 51 having a small side clearance δ with low accuracy may be used, and the pump for softener which is easy to generate side leakage is a gear pump having a small side clearance δ with high precision. 51 is OK.

As described above, in the range of the viscosity of the softener and the liquid lotion to be supplied, by appropriately selecting the supply motors 65a and 65b and the reduction ratio, the "supply amount varies" can be reduced, and the supply accuracy can be improved. effect.

[Eighth Embodiment]

The eighth embodiment will be described using Fig. 38.

Fig. 38 is a schematic view showing a longitudinal sectional view of the detergent tanks 32, 33 of the eighth embodiment. A buoy that is movably supported up and down along the pump means 47 is provided, that is, a buoy 104, and a magnet 105 is disposed below the buoy 104. The buoy 104 includes a magnet 105 and a material and a volume selected to have a specific gravity of 1 or less. The magnet is, for example, a ferrite magnet, and since the specific gravity is larger than 1, the magnet faces downward when the liquid floats. Further, a buoyant guide 106 that extends upward and downward so that the buoy 104 can move only in the up and down direction is provided.

A magnetic sensor 107, such as a Hall IC and a reed switch, is disposed in a position facing the lower surface of the buoy 104 in the tank storage container 34, and the amount of the lotion or softener is reduced, and the liquid level is lowered. When the buoy 104 is lowered to a position close to the bottom surface 46 of the tank, it is turned ON by detecting the magnetic force, and the residual amount is a certain level or more. For example, when the liquid surface is H2, When the buoy 104 is raised to be OFF, the amount of the lotion or the softener can be detected to be reduced.

[Ninth embodiment]

The ninth embodiment will be described using Fig. 39. Fig. 39 (a) shows a state in which the amount of the lotion or the softener is small, and Fig. 39 (b) shows a state in which the amount of the lotion or the softener is more than a predetermined amount.

The difference from the eighth embodiment is that the buoy 104 is extended up and down along the pump means 47, and the upper end of the buoy is extended so that the extension rod 108 passes through the upper surfaces of the tanks 32, 33, and a magnet is provided at the upper end of the extension rod 108. 105, in the drive with the top of the tank 32, 33 The magnet 105 of the moving means 62 is disposed with the portion of the magnetic sensor 107 facing the disposed position.

As shown in Fig. 39 (a), when the residual amount of the lotion is reduced and the liquid level is lowered to H1, the buoy 104 is lowered and the magnet 105 is turned off (OFF) away from the magnetic sensor 107. As shown in Fig. 39 (b), when the residual amount is sufficient in the tanks 32 and 33 and the liquid level is H2 or more, the buoy 104 rises and the magnet 105 abuts against the magnetic sensor 107 to be turned ON. The magnetic sensor 107 is turned off (OFF) to detect that the residual amount is small.

In the ninth embodiment, since the magnetic sensor 107 is disposed in the driving means 62, the wiring from the washing machine body 4 toward the magnetic sensor 107 passes through the shaft hole together with the wiring to the supply motors 65a and 65b. Since the wiring 87 of the washing treatment liquid automatic input means 30 can be collected in only one place, the configuration can be simplified.

[Tenth embodiment]

The tenth embodiment will be described using Fig. 40. Fig. 40 is a schematic view showing a longitudinal sectional view showing the detergent tanks 32, 33 of the tenth embodiment.

A weight sensor 109 for outputting an output signal corresponding to the load is disposed on the bottom surface of the tank storage container 34, and the tanks 32 and 33 are placed on the weight sensor 109, and the output signal of the weight sensor 109 is outputted. It is possible to detect the total weight of the tank itself and the lotion inside the tank. Can be measured from the total weight of the lotion or softener and the tank, and in advance Measure the difference in weight of the tank itself and measure the weight of the lotion or softener. When the weight of the measured lotion or softener is smaller than a predetermined value, it can be judged that the residual amount is small.

As described above, in the eighth to tenth embodiments, it is possible to detect that the amount of the lotion or the softener is small.

[11th embodiment]

Next, the eleventh embodiment will be described using Figs. 41 and 42. Fig. 41 is a block diagram showing the configuration of a control circuit of the washing machine of the seventh embodiment to the tenth embodiment, and Fig. 42 is a control flowchart showing the control configuration of the washing machine of the seventh embodiment to the tenth embodiment.

The block diagram shown in Fig. 41 differs from the block diagram of the first embodiment shown in Fig. 15 in that the supply motor 65 is not provided in a type, but includes a lotion supply motor 65a and a softener supply motor 65b. In the second type, the drive circuit 154 corresponding to each of the supply motors 65a and 65b is provided.

The lotion remaining amount detecting means 79a and the softener remaining amount detecting means 79b may be the configurations described in the eighth embodiment to the tenth embodiment.

The control flow chart shown in FIG. 42 is different from the control flow chart of the first embodiment shown in FIG. 16 in that, after the automatic injection of the lotion in step S109 is set and the process is branched, the process proceeds in step S110. Before the lotion supply motor 65a supplies the lotion in the normal direction, the step of initializing the lotion supply motor 65a by the step S109a is reversed, and before the softener supply motor 65b is supplied to the softener in the forward direction in step S116, In step S116a, the softener is supplied to the motor 65b to reverse the initializing operation.

Next, the supply motors 65a and 65b drive the initializing operation when the pump means 47 is driven to start the supply of the lotion or the softener from the inside of the tubs 32 and 33.

First, since the supply of the lotion or the softener is supplied after the previous washing is performed and the supply operation is completed, the supply motor 65a, 65b is stopped. Therefore, the lotion or the softener is the liquid from the tanks 32, 33. The inside of the supply pipe 54 is filled until the discharge port 56 is filled. However, gradually, the outside air is intruded into the supply pipe 54 from the discharge port 56, and the liquid level in the supply pipe 54 may be lowered to It is impossible to determine what kind of state is the same as the liquid level in the tanks 32 and 33.

Since the liquid level of the lotion or softener is highly different depending on the residual amount in the tubs 32 and 33, the volume of the lotion or softener remaining in the supply tube 54 is at least close to zero and the maximum is full. The amount of tube 54 varies from one to another. In other words, even if the gear pump 51 is supplied with a predetermined amount, the supply amount supplied from the discharge port 56 varies depending on the amount of the lotion or the softener remaining in the supply pipe 54, so that the supply amount accuracy is lowered.

As described above, when the amount of the lotion is supplied to a predetermined amount, the voltage applied to the motor 65 is constant, and the rotational speed of the supply motor 65 is determined, and the driving time of the supply motor 65 is adjusted to a predetermined time. The number of rotations of the gear is set to a predetermined value, so that the desired amount of the lotion can be supplied. Here, the inside of the supply pipe 54 is washed by When the agent or the softener is filled, the amount is supplied to the input field 39, but when the air enters the inside of the supply pipe 54 and the liquid level is lowered, the supply pipe 54 is filled until it is filled. Since the lotion or the softener is not supplied, the supply amount supplied from the discharge port 56 to the input field 39 is subtracted from the amount supplied from the gear pump 51 to the supply pipe 54 until the supply pipe 54 is filled. The amount of quantity.

However, when it is determined that the amount of the supply pipe 54 is filled in a predetermined amount, if the predetermined amount is supplied from the gear pump 51, the expected amount is supplied from the discharge port 56 to the input field 39. . Here, the gear pump 51 is reversely rotated by the reverse rotation of the supply motors 65a and 65b before the supply of the lotion or the softener, and the detergent or the softener in the supply tube 54 is all reversed to the inside of the tubs 32 and 33. In this case, since the liquid level is lowered to the height of the gear pump 51, that is, near the bottom surface of the tubs 32, 33, if the feed motors 65a, 65b are rotated forward, the detergent can be removed from the supply tube 54 each time. The supply operation is started in the state of the softener.

Here, when the lotion or the softener is completely reversed from the inside of the supply tub 54 to the inside of the tubs 32 and 33 during the reverse rotation operation, the liquid level in the supply tube 54 can be surely lowered to the height of the gear pump 51. Therefore, the amount of operation of the reverse operation of the gear pump 51 is determined to be larger than the volume in the supply pipe 54, and the effect of improving the accuracy of the supply amount is obtained.

As described above, the operation of evacuating the detergent or the softener in the supply tube 54 when the gear pump 51 is reversed is referred to as "initialization". Case.

When the supply amount of the lotion or the softener is set in step 108, by adding the volume in the supply pipe 54 to the expected amount, the supply amount supplied from the discharge port 56 to the input field 39 can be made close to the expected amount, and The error in the supply amount is reduced, and the lotion or softener is supplied with high precision.

The "initialization" operation described herein may be performed at the time of completion of the supply of the lotion or the softener, or may be performed before the supply of the lotion or the softener.

When the supply is subsequently reversed to lower the liquid level, since the time until the next washing start is, for example, about 1 day, there is a lotion or softener gradually getting from the gap of the gear pump 51 every time. The ground enters the supply pipe 54 and raises the liquid level to a level equal to the liquid level inside the tank.

On the other hand, when the "initialization" operation is performed before the supply of the lotion or the softening agent, the gear pump 51 is reversely rotated to evacuate the inside of the supply pipe 54, and then the supply operation can be performed, so that the state at the start of the supply operation is Since it is always constant, it is possible to further reduce the error in the supply amount, and it is preferable because the lotion or the softener can be supplied with high precision.

Here, the viscosity range from the softener having the smallest viscosity to the liquid detergent having the highest viscosity is the smallest difference between the maximum supply amount and the minimum supply amount per unit time, that is, the "supply amount varies", and the viscosity is not related. It is preferable to supply a constant supply amount.

And further, when the lotion or softener is added, or When the cleaning of the tanks 32 and 33 is performed, since the driving means 62 is opened rearward together with the tank lid body 31, the coupling receiving portion 64 that transmits the driving force to the pump means 47 through the coupling 61 is exposed. In front of the open drive means 62. When the lotion or the softener adheres to the coupler receiving portion 64, there is a problem that the gap between the outer periphery of the coupler receiving portion 64 is intruded or adhered to the inside of the driving means 62, and the transmission of the driving force is hindered.

[12th embodiment]

Next, a twelfth embodiment will be described with reference to Figs. 43 to 44. Fig. 43 is a perspective view showing the configuration of the washing and processing liquid automatic input means of the twelfth embodiment, in a state in which the tank lid body 31 is opened. Fig. 44 is a schematic longitudinal sectional view, Fig. 44 (a) is a state in which the tank lid body 31 is closed, and Fig. 44 (b) is a state in which the tank lid body 31 is opened and closed to the middle, and Fig. 44 (Fig. 44) c) is a state in which the tank lid body 31 is opened.

The difference between the twelfth embodiment and the seventh embodiment is that it is movably supported along the guide groove 117 provided in the driving means 62, and is opened and closed along the surface facing the coupling receiving portion 64 of the driving means 62. When the sliding cover 110 opens the driving means 62 together with the tub cover 31, the sliding cover 110 is configured to cover the coupling receiving portion 64.

Since the coupling receiving portion 64 is a communication member that transmits the driving force from the driving means 62 to the driving force of the coupling 61, the washing agent and the softening agent are moved from the outer circumference of the rotating shaft and the coupling receiving portion 64 toward the driving means. When the internal invasion of 62 is caused, there is a hindrance to the driving force due to adhesion or the like. The situation conveyed. Here, it is preferable that the lotion and the softener are not dripped onto the coupler receiving portion 64 when the tub body 31 is opened.

That is, the link link 112 is pivoted. The other end of the connecting link 112 is rotatably supported by the connecting link fulcrum 113 provided in the tub storage container 34, and the sliding cover 110 is guided along the guiding groove 117 in conjunction with the opening and closing operation of the tub lid 31. mobile.

When the operation is described in Fig. 44, the grooved lid body 31 shown in Fig. 44(a) is closed, and the slide cover 110 is moved forward. The coupler receiving portion 64 is not blocked. The sliding cover 110 is covered to engage with the coupler 61 provided in the tubs 32, 33, and power can be transmitted from the coupler receiving portion 64 toward the coupler 61.

In the middle of the opening operation of the tub body 31 shown in FIG. 44(b), the sliding cover 110 is directed toward the cover fulcrum 42a by the action of the connecting link 112, that is, the cover is covered. The direction of the receiving portion 64 moves.

In the open state of the tub body 31 shown in FIG. 44(c), the slide cover 110 is a position to cover the coupler receiving portion 64. In the state of Fig. 43 or Fig. 44 (c), since the coupler receiving portion 64 is covered by the sliding cover 110, when the tubs 32, 33 are attached or detached, or when the lotion or the softener is replenished, It is preferred to prevent the lotion or softener from adhering to the coupler receiving portion 64.

[13th embodiment]

The thirteenth embodiment will be described with reference to Fig. 45. Fig. 45 is a schematic longitudinal cross-sectional view showing the configuration of the automatic washing apparatus for the washing treatment liquid according to the thirteenth embodiment, wherein Fig. 45(a) shows a state in which the tank lid body 31 is closed, and Fig. 45(b) shows a groove. The state in the middle of opening and closing of the lid body 31, and Fig. 45 (c) is a state in which the tank lid body 31 is opened.

Different from the twelfth embodiment, in place of the slide cover 110, the swing cover 115 is rotatably supported around the swing cover fulcrum 114 provided in the tub cover 31. Further, the connecting link 112 is rotatably supported around the connecting link fulcrum 113 of the tub storage container 34 at one end, and the other end is rotatably coupled to the connecting portion 111 and the swing cover 115. The ground cover is pivoted, and the swing cover 115 is opened and closed in conjunction with the opening and closing operation of the tub lid 31.

As shown in Fig. 45(a), in a state where the tub body 31 is closed, the swing cover 115 is located at a position rotated forward, so that the coupler receiving portion 64 is not covered by the swing cover 115 and is provided. When the coupler 61 of the tubs 32, 33 is fitted, power can be transmitted from the coupler receiving portion 64 toward the coupler 61.

In the middle of the opening operation of the tub body 31 shown in FIG. 45(b), the swinging cover 115 is directed toward the cover fulcrum 42a by the action of the connecting link 112, that is, the coupling receiving portion 64. The direction of coverage is rotated. As shown in Fig. 45(c), in the open state of the tub body 31, the swing cover 115 is a position to cover the connector receiving portion 64. In the same manner as in the twelfth embodiment, it is preferable because the adhesion of the lotion or the softener to the coupler receiving portion 64 can be prevented.

Here, the viscosity range from the softener having the smallest viscosity to the liquid detergent having the highest viscosity is the smallest difference between the maximum supply amount and the minimum supply amount per unit time, that is, the "supply amount varies", and the viscosity is not related. It is preferable to supply a constant supply amount.

Further, since the amount of the lotion or the softener remaining in the pump means 47 after the application of the lotion or the softening agent is different, there is a problem that the supply amount error occurs due to the difference in the amount.
