Description

Washing machine {WASHING MACHINE}

The present invention relates to a washing machine, in particular a washing machine of a pulsator type.

Generally, a washing machine is roughly divided into a drum type and a pulsator type. The drum type rotates a drum (corresponding to a washing tank) having a horizontal axis of rotation, and utilizes the mechanical action and the chemical action by the detergent when the laundry falls in the drum by the rotation. For dewatering, the drum is rotated and centrifugal force is used. In addition, drying of the laundry after dehydration rotates the drum, blowing a warm air into a drum.

In contrast, the pulsator method rotates the pulsator disposed at the bottom of the washing tank (or washing and dehydrating tank), generates "current flow" by the rotation, and causes mechanical action such as friction or vibration and detergents. Remove dirt by chemical action In addition, the washing tank is rotated and the centrifugal force is used for dewatering the washed laundry. In addition, drying of the laundry after dehydration is performed by blowing warm air into a washing tank, rotating a pulsator and stirring laundry.

(A) A pulsator which performs the above functions greatly influences the drying performance. For this reason, conventionally, the upper surface of a pulsator is formed in four slopes, and by doing so, the laundry is moved and moved, and the drying performance is improved (for example, patent document 1, 2).

(B) Since the foam is generated during the washing, the foam is not allowed to flow out of the washing tank, or the foam is spilled out of the washing tank so that it does not spill out of the storage tank housing the washing tank. The invention which makes or does is disclosed (for example, refer patent document 3).

(C) Generally, a washing machine has a water storage tank (same as a water tank) in which washing water is stored, and a washing tank (collectively referred to as a dehydration washing tank and a dehydration drying washing tank). The washing water circulated from the washing tank is circulated in order to install a filter that captures dust (cloth pieces, seams, etc.) floating in the washing water, or to spray water for removing bubbles on the surface of the washing water. Circulating water channel is formed. At this time, a rear wing is formed on the lower surface of the base of the pulsator provided in the washing tank as a water supply means to the circulation channel, and a pump chamber is formed by the rotating pulsator, the casing surrounding the pulsator, and the lower surface of the washing tank. The invention which tries to improve pump performance is disclosed (for example, refer patent document 4).

(D) In addition, laundry, such as thin socks, is drawn into the gap between the pulsator disposed freely at the bottom of the washing tank (or washing and dehydrating tank) and the main wall surface of the washing tank, so that the rotation load torque of the pulsator There is a problem that increases. Therefore, various techniques have been proposed to solve this problem. For example, the shape of the upper surface of the pulsator is configured to have a plurality of raised portions gently raised in the circumferential direction, so that the laundry is placed on the pulsator. There is a technique that generates a rubbing force that repeatedly acts on the component force of the washing tank, and by placing a stone piece corresponding to the ridge shape of the ridge of the pulsator on the main wall surface of the washing tank to prevent the intervening (e.g., See Patent Document 5).

(ㅁ) Moreover, the washing | cleaning liquid is discharged into the washing tank from the discharge port of a washing tank upper part through the opening part and the water path provided in the bottom by the back wing of the stirring blade provided in the bottom, and it circulates (for example, refer patent document 6). .

In addition, as another washing machine, a pump chamber is formed in the outer circumference of the rear wing provided in the pulsator (stirring wing), and the pump chamber is provided to the water discharge port formed in the upper part of the washing / dehydrating tank through the circulation channel. Some water is transmitted (for example, refer patent document 7).

(A) However, in the structure of the pulsator disclosed in Patent Literatures 1 and 2, when attempting to secure an inclined surface for moving laundry, the volume of the pulsator itself is increased, resulting in a decrease in washing / drying capacity or a usable quantity. There is a problem of decreasing. In addition, there also exists a problem that the load of the motor which drives a pulsator becomes large.

(B) In addition, the invention disclosed in Patent Document 3 discloses that the washing water discharged by the pumping action of the rear blade provided on the back side of the pulsator is scattered in the washing tank so that foam does not flow out of the washing tank, or Since the foam spilled to the outside is scattered between the washing tank and the storage tank so as not to flow out of the storage tank, a predetermined defoaming effect can be obtained, but there are the following problems.

That is, since this invention aims at spraying wash water to clothes to the last, the upper part of a circulation water path is opened to the air | atmosphere, and washing water was not ejected vigorously. That is, since only the hydrostatic pressure (at most, hydrostatic pressure resulting from the difference between the height of the upper portion of the circulation passage and the height of the through hole) is applied to the through hole formed in the circulation passage, the washing water is classified by the pressure generated by the pulsator. It is not. For this reason, there exists a problem that "dirt" adheres to the outer surface of a washing tank or the inner surface of a water storage tank after defoaming (foam removal), and the said dirt is not removed. In addition, there is a problem that the dirt caused by the splash of the wash water is not removed.

(C) In addition, the invention disclosed in Patent Document 4 forms a seal portion of a labyrinth structure between a washing tank and an outer circumferential edge of a pulsator. Specifically, an annular rib is formed on the rear side of the pulsator. Then, the annular ribs are replaced on the outer surface of the casing through a minute gap, or a flat part is formed on the rear side of the pulsator, and the flat part is placed through a minute gap on the jaw formed in the casing.

That is, since relatively large cylindrical surfaces or flat surfaces are replaced by minute gaps, the original labyrinth (maze) is not formed, and the washing water discharged from the pump chamber flows out and is not sufficiently supplied to the circulation channel. There is a problem.

(D) In addition, in the invention disclosed in Patent Document 5, the washing tank (or washing and dehydrating tank) and the pulsator do not always rotate integrally, and the pulsator may rotate relative to the washing tank. The height of the gap between the circumferential wall surface of the washing tank and the outer circumferential surface of the pulsator is changed by the rotation of the pulsator. Due to the change in the height, problems such as inheriting of clothing have not been sufficiently solved.

That is, for example, considering the case where the laundry enters the gap formed between the low portion of the ridge of the pulsator and the washing tank, the position of the ridge is moved by the rotation of the pulsator, and the height of the gap portion where the laundry enters is increased. By gradually increasing, it is considered that the laundry does not come out while entering, and soaking occurs.

(ㅁ) In addition, in the washing machine described in Patent Document 6, since the opening portion is larger than 100 mm, the amount of washing water discharged from the discharge port increases, but the center portion of the vortex generated by the stirring blade is the front side. Washing water falls to the side, and washing water does not reach the laundry evenly, and the quantity of water required for washing is increasing.

In addition, in the washing machine described in Patent Document 7, the washing water passing through the circulation water passage is arithmetic by the arithmetic opening, but since the washing water is set to wash the laundry set on the upper surface of the partition body disposed above the pulsator, the partition body is used for washing. It is needed.

This invention is made | formed in view of the said subject, and an object of this invention is to provide the following pulsator type washing machine.

(A) It is possible to improve the drying performance of the laundry while reducing the washing / drying capacity and the quantity of water available as little as possible, and reducing the increase in the load of the motor driving the pulsator as much as possible.

(B) In addition, dirt may be prevented from adhering to the outer surface of the washing tank or the inner surface of the water storage tank, or the dirt may be removed even if it is attached.

(C) Moreover, the performance (henceforth a "water resistance" may be called hereafter) which prevents the wash water discharged | emitted from a pump chamber can be improved.

(D) It is possible to prevent the laundry from being picked up or interrupted, and also to reduce the load torque applied to the motor driving the pulsator.

(ㅁ) The washing water in the washing and dehydrating tank can be uniformly brought into contact with the washing water without using tools such as partition bodies.

(Iii) In the third washing machine according to the present invention, since the original labyrinth (cross-sectional L-shaped or cross-sectional c-shaped) is formed between the pulsator and the casing, it is difficult to drain the water. Is improved). As the amount of wash water circulated increases with this, the trapping of particles floating in the wash water is promoted, and the disappearance of bubbles generated on the water surface and the washing of the inner surface of the water tank are promoted.

(Iii) The fourth washing machine according to the present invention is formed such that the upper surface of the bottom wall positioned outside the pulsator in the washing and dehydrating tank and the upper surface of the outer peripheral portion of the base portion of the pulsator are the same surface, Since the height positions of the boundary portions between the washing / dehydrating tank and the pulsator are not relatively changed during rotation, it is possible to prevent the entry or interruption of the laundry into the gap, thereby further driving the pulsator. It is possible to reduce the load torque applied to the motor.

(v) The fourth washing machine according to the present invention is adapted to the type of washing machine (for example, the inclined state of the water layer, the capacity, etc.) by a water flow derivative provided separately and detachably from the channel body. The angle of the washing water can be injected at a predetermined angle from the discharge port, and the laundry can be evenly rotated by the vortex, and the laundry can be washed efficiently.

The water tank 1002 is housed in the body 1001. The water tank 1002 is a tubular shape in which the ceiling surface is opened, the bottom surface is closed, and is fixed to the tilt table 1020. On the upper end surface (similar to the periphery of the ceiling surface opening) of the water tank 1002, a water tank cover 1007 having an inner opening is provided. In addition, the tank cover 1007 is provided with a cover 1008 that freely closes or opens the opening of the tank cover 1007. In this example, the inner cover 1008 is disposed below the outer cover 1009.

The opening and closing operation of the outer cover 1009 is transmitted to the inner cover 1008 by an interlocking mechanism (not shown). When the outer cover 1009 is opened, the inner cover 1008 is also opened, and when the outer cover 1009 is closed, the inner cover is closed. 1008 is also closed.

Moreover, the cover lock mechanism (not shown) which locks the outer lid 1009 (or inner lid 1008) incapable of opening is provided. Such a cover lock mechanism may be mechanically performed by using an advancing or retracting electronic pin or the like. When the outer cover 1009 (or the inner cover 1008) is opened and closed by an electric cover opening and closing drive mechanism, the cover opening and closing is opened. The drive mechanism may not be electrically driven.

(Washing tank)

The washing tank 1005 is also referred to as a washing / dehydrating tank or a washing / dehydrating / drying because it is provided for washing, rinsing, dehydrating, and drying the put laundry. The washing tank 1005 is disposed freely in the water tank 1002. That is, since the water tank 1002 is fixed to the tilt table 1020 and the tilt table 1020 tilts, the washing tank 1005 tilts with the water tank 1002. The washing tank 1005 has a tubular shape in which the ceiling surface is opened and the bottom surface is closed, and a plurality of water passage holes for dewatering are formed in the side surface.

A balancer 1006 is provided around the ceiling opening of the washing tub 1005. The range enclosed by the inner circumference of the balancer 1006 is provided to inject or take out laundry as an opening part. Moreover, since the water tank cover 1007 is provided in the water tank 1002 which accommodates the washing tank 1005, the upper end surface of the balancer 1006 is covered and covered by the water tank cover 1007. FIG.

(Pulsator)

In the bottom part of the washing tank 1005, the pulsator 1004 for stirring the thrown laundry and poured water (henceforth "washing water") is arrange | positioned freely. Hereinafter, in order to distinguish it from the rotation of the washing tank 1005, the rotation of the pulsator 1004 is called "swing".

FIG. 2 is a perspective view showing a pulsator 1004 used in this embodiment, and FIG. 3 is a side view of the pulsator 1004 as seen from the arrow X direction in FIG. 2. The pulsator 1004 has a disk-shaped base portion 1004a formed on the surface (top surface 1004A) and an inclined surface of the base portion 1004a by having an inclined surface formed by lowering one end side of the upper surface thereof and increasing the other end side opposite thereto. Protruding from the inclined surface of the inclined surface and extending along the inclined direction of the inclined surface, and having a wing portion 1004b having a shape crossing the center portion of the base portion 1004a, and protruding height from the slope of the base portion 1004a of the wing portion 1004b, The height of the base portion 1004a is made higher toward the higher side from the lower side. In addition, the code | symbol 1004B in the figure has shown the back surface (bottom surface) of the pulsator.

By setting the pulsator 1004 in such a structure, it is possible to secure an inclined surface sufficient to move the laundry while keeping the volume of the pulsator small. In this way, it is possible to improve the drying performance of the laundry while reducing the washing / drying capacity and the number of usable water as little as possible and increasing the load of the motor driving the pulsator as much as possible.

In addition, the water drain hole 1004c provided in the pulsator 1004 is provided in the area | region on the side lower than the height of the base part 1004a high. Thereby, since the amount of drainage from the part where the height which water collects easily is low, the drainage efficiency from the washing tank 1005 improves.

4 shows a modification of the pulsator 1004 and is a sectional view in a line orthogonal to the longitudinal direction of the wing portion 1004b of the pulsator 1004. The pulsator 1004 of FIG. 4 is formed in both side views of the base part 1004a which fell to the wing part 1004b by the inclined surface which rises toward the direction of the blade part 1004b from the edge part. As a result, when the pulsator 1004 rotates, the laundry springs up toward the top of the wing portion 1004b along the inclined surface, thereby further promoting the movement of the laundry, and further improving the drying performance of the laundry.

As for the wing part 1004b of the pulsator 1004 demonstrated so far, the left-right wall surface of the wing part 1004b along the inclination direction of the inclined surface of the base part 1004a is formed in the same inclination (for example, 4, the inclinations of the left and right wall surfaces may be different from each other. In that case, it is preferable to form one wall surface as a steep surface which exerts the force of the circumferential direction with respect to the laundry, and the other wall surface as a gentle surface which exerts the force of the up-down direction with respect to the laundry, respectively. 5 is an operation explanatory diagram for explaining the operation of the wing portion 1004b configured as described above. When the pulsator 1004 is turned (electrostatic and inverted), the steep wall surface 1004s acts to exert the force to extrude the laundry 1050 in the horizontal direction, and the gentle wall surface 1004 g is the laundry 1050. It also contributes to moving up and down). Therefore, the wall surface 1004s having a steep slope exerts an effect during washing or rinsing, and the wall surface 1004g having a gentle slope exerts an effect during drying.

The pulsator 1004 may be an integrally molded product in which the base part 1004a and the wing part 1004b are integrally molded, and the base part 1004a and the wing part 1004b are formed as separate members, The assembled assembly may be sufficient. If the base portion 1004a and the wing portion 1004b are integrally molded with a resin or the like, the cost can be reduced in terms of the number of parts and the assembly workability. On the other hand, if the base portion 1004a and the wing portion 1004b are separate parts, a metal material having good thermal conductivity (for example, stainless steel, etc.) from the viewpoint of drying performance, or a member is suitably selected from the viewpoint of designability. You can choose.

The pulsator 1004 is provided with one row of the wing portions 1004b, but the wing portions 1004b may be arranged in double rows depending on the situation.

As shown in FIG. 13, a plurality of pump-up vanes 1004k for pumping water are provided radially on the rear surface (bottom surface) 1004B of the pulsator 1004.

In addition, in order to smoothly rotate (rotate) the pulsator 1004, it is preferable that the center is located on the rotation axis of the pulsator 1004. For that purpose, it is preferable to implement various aspects for balance adjustment to the base portion 1004a and / or the wing portion 1004b in correspondence with the shape of the pulsator 1004.

For example, the thickness of the bottom face side of the base part 1004a and / or the wing part 1004b is adjusted in correspondence with the shape of the pulsator 1004, and a center position is located on a rotation axis. The thickness adjustment of the pulsator 1004 can be performed, for example, by forming a cavity in the bottom face side (rear side) of the one where the height of the pulsator 1004 is higher, and reducing the weight of the part.

Alternatively, one or more three-dimensional weights on the bottom side (lower side) of the base portion 1004a and / or the wing portion 1004b on the side of which the mass is small with respect to the center of the rotation axis of the pulsator 1004. (Or a convex portion) can be added, whereby the balance can be adjusted by increasing the weight of the portion.

As the three-dimensional weight portion (or the convex portion), for example, at least one rib provided in the vicinity of the pump-up vane 1004k on the bottom surface side (back side) of the base portion 1004a and / or the wing portion 1004b. (Or rib group) 1004m, 1004n, and the like. In addition, when the rib is used as an arc-shaped rib in the rotational direction of the pulsator 1004, the resistance of water accompanying the turning of the pulsator 1004 can be reduced.

In addition, the pulsator 1004 is preferably arranged so that the center (here, referred to as the dynamic center) at the time of turning (rotation) is also located on the rotation axis of the pulsator 1004. Therefore, the volume of the space partitioned by the adjacent pump up vane 1004k on the back of the base 1004a is centered on the rotation axis (corresponding to the central hole in FIG. 13) of the pulsator 1004. It is good to form so that it may become substantially equal in the area | region which opposes. For that purpose, for example, a part of the back surface side of the base portion 1004a is formed of a non-invasive low density member. More specifically, for example, so that water does not invade part or all in the height (depth) direction of the space partitioned by the neighboring pump up vane 1004k on the back side of the pulsator 1004. The cover is provided to form a watertight structure so that the volume of the space generated on the back side of the pulsator 1004 is approximately equal in the areas facing each other about the rotation axis of the pulsator 1004. It is desirable to. As the non-invasive low density member, a foamed resin material composed of independent bubbles, for example, expanded polystyrene, can be used.

(Rotary motor)

A bottom surface of the water tank 1002, and a common rotary motor 1011 for rotating the pulsator 1004 and the washing tank 1005 are provided on the bottom surface of the tilt table 1020. In addition, rotation distribution means for distributing rotation of the rotary motor 1011 to the pulsator 1004 or the washing tub 1005, and a pulsator for transmitting rotation (orbiting) to the pulsator 1004 from the common rotation distribution means. Side rotation transmission means and a coarse rotation transmission means for transmitting rotation to the washing tub 1005 from the common rotation distribution means are provided, but these means are not particularly shown. The rotation motor 1011 and the rotation distribution means perform predetermined rotation / stop and distribution in the washing stroke, the dehydration stroke and the drying stroke, respectively, by the command of the control means.

(Water supply and drainage mechanism)

On the ceiling surface of the water tank 1002, a water supply mechanism 1013 is provided on the lower surface side of the water tank cover 1007. The water supply mechanism 1013 includes a water supply path 1012 whose one end is led out of the body 1001 and connected to an external water supply, and a water supply valve 1014 which is provided in the middle of the water supply path 1012 and opens and closes the flow of water. Have

A drain hole (not shown) is formed at the bottom of the water tank 1002, and a drain hose 1018 is connected to the drain hole. In addition, a drain valve (not shown) is provided in the drain or drain hose 1018 to open and close the flow of water. Therefore, when the water supply valve 1014 and the drain valve are closed, and the lid | cover 1008 is closed, the water tank 1002 will be in a closed state.

(Drying means)

The drying means drys laundry by hot air, and has a drying fan 1015 for supplying warm air into the washing tank 1005 during the drying stroke, and a heater 1017 for heating air.

The drying fan 1015 is provided on the lower surface of the horizontal stage 1019, and a heater 1017 is provided at the casing discharge port of the drying fan 1015. And the blower duct 1016 which communicates with the said casing discharge port, stands along the outer wall of the water tank 1002, and opens to the opening edge of the upper part of the water tank 1002 is provided. In addition, since the blowing duct 1016 has flexibility near the communication part with a casing discharge port, it is tilted with tilting of the water tank 1002. In addition, when such a drying means is provided in the tilting platform 1020, flexibility is not required for the blowing duct 1016.

The warm air heated by the heater 1017 is discharged to an exhaust duct (not shown) after being provided for drying the laundry in the washing tank 1005. And after performing "water cooling dehumidification" which waters toward this discharged warm air, it is sent to the ventilation duct 1016 again, and circulates.

(Tilt movement of tank)

The tilting operation of the water tank 1002 which inclines the water tank 1002 as shown in FIG. 6 can be performed by various methods. For example, it can carry out by rotating the tilting platform 1020 about the tilting point 1020a using a motor, a pinion, and a rack. Moreover, the water tank 1002 can also be inclined by moving the back hanging rod 1003 which supports the water tank 1002.

(Control means)

FIG. 7 is a block diagram illustrating a configuration of control means for controlling the operation of the washing machine shown in FIG. 1. The control means 1110 of the washing machine is connected to the CPU 1130, the input interface 1120, the output interface 1140, the memory 1150, and the clock control unit 1160 (timer 1170). Has). Various operation switches (indicated by "... SW" in the drawing) and tilt angle detectors, such as a driving course setting switch and a power switch, which input predetermined signals to the CPU 1130 through this, are connected to the input interface 1120. The drying interface 1015 or the motor (rotary motor 1011 of the washing tub 1005 and the tilting motor of the water tank 1002, etc.) to which the predetermined control signal from the CPU 1130 is outputted to the output interface 1140. And generically).

In addition, the safety SW has shown the switch which confirms that the cover lock mechanism which locks the opening / closing of the outer cover 1009, the tilt lock mechanism which locks the tilt of the tilting platform 1020, etc. is working. .

The memory 1150 also stores control conditions corresponding to the respective strokes of the driving course. The CPU 1130 issues a determination of the inclination angle and a control command for tilting at the determined inclination angle according to each stroke of the driving course.

(Control of washing machine)

8 to 10 illustrate an example of a control method of the control means 1110, where FIG. 8 is a schematic flowchart of a series of strokes of the washing machine, and FIGS. 9 and 10 are time charts of a series of strokes of the washing machine. An example of each is shown. In FIG. 9, the washing tank 1005 is inclined in the washing stroke and the drying stroke. In FIG. 10, the washing tank 1005 is standing upright during the washing stroke and the drying stroke.

This washing machine is capable of executing a washing stroke, a rinsing stroke, a dewatering stroke, and a drying stroke of the laundry, and the user can appropriately set a "driving course".

A description with reference to FIG. 8 is as follows.

(i) In the initial stroke, when the power switch is turned ON, the washing tank 1005 is inclined.

(Ii) When the washing operation is included in the set driving course, when the amount of laundry put is large, when the washing machine 1005 is erected, "upright washing" is performed, and the amount of laundry put is small. The "inclined washing" which wash | cleans in the state which inclined the washing tank 1005 is performed.

(Iii) When the rinse stroke is included in the set driving course, the "standing rinse" for washing in the state in which the washing tank 1005 is upright is performed regardless of the amount of laundry put.

(Iii) When the dehydration stroke is included in the set driving course, the " upright dehydration " for dewatering in the state in which the washing tank 1005 is upright is performed regardless of the amount of laundry put.

(v) In the case where the set driving course includes a drying stroke, when the amount of laundry put is large, when the washing tank 1005 is placed upright, " upright drying " In this case, "tilt drying" that is dried while the washing tank 1005 is inclined is performed.

(Iii) In the boil stroke, the power switch is automatically turned off (0FF), and the washing tank 1005 is inclined. And when taking out the laundry is completed and a cover is closed, the washing tank 1005 will stand up and a series of strokes will be complete | finished. In addition, the washing tank 1005 can be left inclined.

Next, based on the time chart of FIG. 9, the flow of the washing control will be described with reference to FIG. 10 in part.

(S1-S2: Power ON, Laundry input)

In FIG. 9, waiting for the ON of the washing machine to be turned ON, the washing tank 1005 is tilted at, for example, 20 degrees, and after completion of tilting, the lid of the lid 1008 and the outer lid 1009. The lock is opened. Then, since the lid 1008 and the outer lid 1009 can be opened and closed freely, the user can open the outer lid 1009 appropriately (the lid 1008 is also linked to open) to inject laundry into the washing tub 1005. Can be. At this time, since the washing tank 1005 is inclined, it is easy to insert laundry.

In addition, when the power is turned off (0FF) while the washing tub 1005 is inclined, the tilt of the washing tub 1005 is mechanically locked, and the inner lid 1008 and the outer lid 1009 are free to open and close. Therefore, the user can appropriately open the outer lid 1009 (the lid 1008 is also opened in conjunction) and put the laundry into the washing tub 1005. At this time, since the washing tank 1005 is inclined, as described above, it is easy to put laundry.

(S3-S4: course setting, load detection and determination of water supply and inclination angle)

When the user sets the driving course, turns on the operation switch (ON), the outer cover 1009 (or cover 1008) is closed, and the outer cover 1009 (or cover 1008) is incapable of opening. Is locked.

In addition, once the outer cover 1009 (or the inner cover 1008) is locked, the cover lock is closed unless the power switch is turned off (0FF) or the entire stroke of the set driving course is terminated. It is not released.

Next, a load amount (weight of laundry put in) is detected by a well-known method. That is, after the rotary motor 1011 is started to rotate the pulsator 1004 by a predetermined amount, the rotary motor 1011 is stopped and the weight of the laundry is the inertia rotation amount of the pulsator 1004 after the stop. (A value that can be converted into a "load amount") is detected.

Based on the detection result of the load amount, the main water amount and the inclination angle of the washing tub 1005 in the washing stroke (the center of gravity is equal to the angle formed in the vertical direction) are determined.

For example, when the tank 1002 is about 540 mm in diameter and about 540 mm in depth, when the weight of the laundry detected is about 6 kg or less, the inclination angle is 30 degrees. Then, as will be described later, the washing performance is improved, and a sufficient amount of water penetrating the laundry can be ensured.

On the other hand, for example, when the weight of the laundry to be detected is greater than about 6 kg, as shown in FIG. 10, the inclination angle is 0 degrees, that is, the water is sufficient to penetrate the laundry by inverting the washing tank 1005 without being inclined. While ensuring, the water in the washing tank 1005 does not overflow during washing (hereinafter, referred to as "upright washing method").

(S5: Joju and Kyungdong)

Then, water and tilting are executed based on the above determination. That is, the tilting motor 1020 installed in the horizontal stand 1019 is driven to tilt the tilting stand 1020 on which the washing tub 1005 is fixed. That is, the control means outputs the tilt tilt command to the tilt motor. The tilt motor is stopped when the tilt angle detector detects that the tilt angle is 20 degrees or when the tilt angle detector (corresponding to the position sensor) installed at the position of the tilt angle is 20 degrees.

In addition, after the water is finished (after the water supply valve which has been opened once), the washing is started and washing is started during the tilting, but the pumping may be performed in parallel with the tilting or after the end of the tilting. .

In particular, in the upright washing method shown in Fig. 10, it is preferable that water be poured after the end of tilting so that water does not leak from the water tank 1002, or that tilting is terminated before the pouring amount approaches.

(S6: laundry)

In the washing, the tilt lock mechanism operates while the washing tank 1005 inclines the inclination angle to 20 degrees, and in the locked state, the pulsator 1004 rotates at low speed. And when the completion | finish of washing | cleaning stroke is near, the rotational motor 1011 is decelerated and stopped while opening a drain valve and draining.

(S7: Kyungdong)

When the drainage is finished, the tilt lock mechanism is opened, and the tilt of the washing tank 1005 is started to stand upright. That is, the tilting motor provided in the horizontal stand 1019 is driven again, and the tilting stand 1020 in which the washing tank 1005 is fixed is tilted.

Then, when the inclination angle detector detects that the inclination angle is 0 degrees or when the inclination angle detector installed at the position of the inclination angle is 0 degrees, the tilt motor is stopped and the washing tank 1005 is bottomed. It should be perpendicular (same as vertical) to (床 面).

In addition, the tilt lock mechanism may be opened before the drainage ends, and the tilt of the washing tub 1005 may be started. For example, even when a driving course that does not include a rinsing stroke is set, the washing of the laundry at the end of the washing stroke can be reduced by executing the washing for a predetermined time in the washing tub 1005 in an upright state before the washing stroke is finished. Therefore, the unbalance of rotation in the dehydration stroke immediately after that can be reduced.

(S8: Rinse)

Rinsing is performed by operating (locking) the tilt lock mechanism in the state where the washing tank 1005 is upright. In Fig. 9, the rotary motor 1011 is rotated at a low speed while water is supplied, and after the predetermined amount of water is supplied, the water supply is stopped, but the rotation is continued, and then, the rotation motor 1011 is decelerated and stopped immediately before the end of the rinsing. The drain valve is opened together to allow drainage. However, the present invention is not limited to this control.

For example, you may insert water dehydration stroke which rotates the washing tank 1005 at high speed on the way, and can carry out rinse water → rinse → dewatering → rinse water → rinse. At this time, since the washing tub 1005 is standing upright, generation of vibration and noise is suppressed even when the washing tub 1005 is rotated at a high speed.

That is, even when the laundry at the end of the washing stroke is biased to one side of the washing tank 1005, the rinsing of the washing tank 1005 is performed by standing up and performing the washing, so that the bias of the laundry is eliminated, and thus the vibration in the subsequent dewatering stroke. In addition, noise can be reduced.

In addition, before starting the water for the rinsing stroke, the rotary motor 1011 is rotated (for example, rotates at about 800 rpm) at the state where the drain valve is opened, and "intermediate dewatering (washing tank 1005). Rotation) "may be performed, and water and rinsing (orbiting of the pulsator 1004) and drainage may be performed simultaneously.

(S9: Dehydration)

Dewatering is performed by rotating the washing tub 1005 at high speed by the rotating motor 1011 in a state where the washing tub 1005 is standing upright. At this time, since the unloading force (force acting at an angle to the rotating shaft) of the gravity component does not act on the washing tub 1005, the rotation is stabilized. Therefore, even if the laundry in the washing tub 1005 is biased, severe vibration and noise are not generated during high-speed rotation, and the washing tub 1005 and the water tank 1002 do not collide with the body 1001.

(S10: tilt)

When the dehydration is finished, the tilt lock mechanism is opened, and the tilt of the washing tank 1005 is started and tilted. That is, the tilting motor is driven again, for example, when the tilting angle detector detects that the tilting angle is 30 degrees, or when the tilting angle detector provided at the position of the tilting angle is operated is stopped. In addition, the tilt lock mechanism is operated (locked).

(S11: dry)

Then, the heater 1017 is energized (ON), the drying fan 1015 is started (ON), and warm air is supplied to the water tank 1002 via the blowing duct 1016. In the meantime, in the state in which the washing tank 1005 is inclined, "stirring rotation" by inversion of the pulsator 1004 is performed, an asymmetrical force acts on the laundry, and the washing tank 1005 is in an upright state. Stirring of laundry can be accelerated | stimulated more than ever, it can dry efficiently and can reduce dry unevenness. However, when the amount of laundry put in is large, as shown in FIG. 10, you may dry with the washing tank 1005 upright. "Stirring rotation" refers to the operation of inverting the pulsator 1004 largely and changing the laundry.

In particular, by the rotation of the pulsator 1004 having the characteristic structure as described above, the vertical movement of the laundry is promoted, and the drying efficiency is improved. In addition, in the case of a drying stroke, it is preferable to make the rotation speed of the pulsator 1004 the left-right direction faster than the case of a washing stroke, in order to improve drying efficiency.

In the drying stroke, the rotary motor 1011 and the drying fan 1015 may be started in parallel with the tilting operation. 9 and 20, opening the water supply valve 1014 during the drying stroke slightly supplies water to the washing tank 1005 (directly waters to the laundry) to prevent static electricity, or to change the water supply direction using a switching valve (not shown). It is for changing the warm air after giving it to drying of laundry to turn toward the warm air in a duct when it returns to the inside of a circulating duct. That is, it is for promoting the dew condensation of the water (containing in the warm air) evaporated from the laundry. However, the water supply may be stopped in the drying stroke.

(S12: tilt)

When the drying stroke is completed, the tilt lock mechanism is opened, the washing tank 1005 is tilted again, and the tilt angle is 20 degrees. In addition, immediately before the end of the drying stroke, the washing tank 1005 may be started in parallel with drying.

(S13: take out)

Then, when the tilt angle reaches 20 degrees, the lid lock is released on the condition of the operation (lock) of the tilt lock mechanism and the stop of the rotary motor 11. Then, the user can open the outer lid 1009 (the lid 1008 also opens in conjunction), and can easily take out the laundry from the washing tub 1005. At this time, since the washing tank 1005 is inclined, it is easy to reach the inside of the washing tank 1005, and since the upper opening of the washing tank 1005 faces the user's gaze direction, to the bottom of the washing tank 1005. Easy to peek In addition, when the amount of laundry is large, the user may be able to designate a default position, and the washing tank 1005 may be erected on the occasion of taking out the laundry.

(S14: tilt)

Then, when the laundry is taken out and the outer lid 1009 (and the inner lid 1008) is closed, the washing tub 1005 is upright, and in this upright state, the lid lock is opened (opening is free).

(S15: End)

Then, the power switch is automatically turned off (0FF), and the series of steps are all finished.

At this time, since the inclined stand 20 is supported in a wide range of the horizontal stand 1019, the own weight such as the water tank 1002 does not concentrate and act on the tilting point 1020a. Therefore, the tilting point 1020a is opened from the load over a long time, and the durability is improved.

In addition, the user may be able to designate a default position, and may end the washing tank 1005 in an inclined state.

(Tilt effect)

When the washing tank 1005 is rotated upright, the water surface forms a rotationally symmetrical plane about the rotation axis, whereas when the washing tank 1005 is inclined and the water surface is asymmetrical with respect to the rotation axis. Therefore, the force acting on the laundry and the laundry in the washing tank 1005 becomes asymmetrical with respect to the rotation axis, and the water flow and the movement of the laundry become complicated as compared to when the washing tank 1005 is in an upright state, and the washing power increases, and washing Also less stains.

(Determination of tilt angle)

In the above description, the inclination angle of the washing tank 1005 in the washing stroke is 30 degrees, and the inclination angle of the washing tank 100 in the input or take out of the laundry and in the drying stroke is illustrated as an example of 20 degrees, but the present invention is not limited thereto. In the washing stroke, the predetermined tilt angle can be determined according to the amount of laundry (corresponding to the load) within the range of 20 to 45 degrees. Incidentally, the inclination angle can be selected within the range of 0 to 30 degrees at the time of loading or taking out the laundry, and at the drying stroke. That is, as described above, since the inclination angle for maximizing the cleaning performance also varies depending on the shape and size of the washing tank and the amount of laundry to be put in, the determination of the inclination angle (washing stroke) in consideration of such a variation factor is made. desirable.

In addition, the inclination angle at the time of loading / unloading the laundry is preferably determined in consideration of the elongation of the user, the size of the body, and the like. In addition, each user may set the angle of inclination with which each user has a comfortable feeling. At this time, the opening formed in the top cover 1010, that is, the outer cover 1009 is formed by the washing tank 1005 in order to respond to a request to put or take out the laundry while the washing tank 1005 is upright. Since it is necessary to make it the size which can take out a laundry at the time, for example, when it projects on the horizontal surface, the upper opening (corresponding to the inner lid 1008) of the washing tub 1005 at the time of standing up is the outer lid 1009. ) To be included (covered). That is, the outer cover 1009 becomes long toward the rear side.

In addition, when the inclination angles before and after tilting are made the same, for example, when any stroke is executed at the same inclination angle, for example, tilting when the laundry is introduced and then shifted to the washing stroke or drying As a matter of course, when the laundry shifts from the administration to the take-out, it is of course unnecessary. That is, the time required for a series of driving courses can be shortened, and the load on the tilting mechanism can be reduced so that the time required for tilting (change of the tilt angle) becomes unnecessary.

Incidentally, the inclination angle in the washing stroke or the drying stroke is not limited to one, but may be varied stepwise by selecting one or two or more inclination angles within the range of 20 to 45 degrees or 0 to 30 degrees. The angle of inclination may be continuously changed within the range, that is, the distance between the minimum angle of inclination (including upright) and the maximum angle of inclination may be reciprocated twice or twice. At this time, the washing process is improved by generating more complicated water flow and washing the laundry, and the washing performance is improved by drying, so that the warm air can be included in the bundle of the laundry. Improves.

(Rotation control of pulsator)

As shown in FIG. 4, when both wall surfaces of the wing portion 1004b of the pulsator 1004 are formed of a steep slope and a slope, the rotation speed and the rotation time in the left and right directions (electrostatic direction and reverse direction) It is better to make them different. For example, when the pulsator 1004 rotates to the slope surface side of the wing portion 1004b, the pulsator 1004 rotates in the steep slope side direction of the wing portion 1004b so as to reliably move the laundry 1050 up and down. Speed everything up. In addition, in order to prevent tangling of the laundry 1050, it is preferable that the time to rotate to the steep surface side direction of the wing part 1004b is shorter than the time to rotate to the slope surface side direction of the wing part 1004b.

In addition, as shown in FIG. 11, the height of the pulsator 1004 is shown at the end of the stroke (end of rotation of the pulsator 1004) which rotated the pulsator 1004 in the state in which the washing tank 1005 was inclined. The lower side is positioned on the rising side of the inclined washing tank 1005, and the laundry 1050 is taken out of the washing tank 1005 while eliminating the bias in the washing tank 1005 of the laundry 1050. It is preferable to make it easy. In addition, at the time of drainage, it is preferable to rotate the pulsator 1004 from the position of FIG. 11, and to drain in the state similar to FIG.

(Application to other washing machines of the pulsator described in the above embodiments)

In the said embodiment, although the pulsator 1004 peculiar to this application was applied to the washing machine of the type which performs predetermined | prescribed stroke in the state which inclined the washing tank 1005, the pulsator system 1004 of this application is a pulsator system. Needless to say, it can be applied to any washing machine employing.

Then, by lowering one end side and increasing the other end side opposite thereto, an inclined surface is formed on the upper surface, and the washing tank is inclined in the forward direction and provided with a stroke for rotating the pulsator in a state where the washing tank is inclined. The drying performance can be improved even when the washing tank is inclined.

In addition, a washing stroke and a rinsing stroke may be collectively called a "washing stroke."

(Body)

The body 2010 is a cylindrical shape (similar to a substantially rectangular parallelepiped) of a rectangular cross section, and a top cover 2011 is provided on the ceiling surface. The top cover 2011 has a body opening portion 2012 formed therein, and serves as a clothes inlet for providing access to clothes. The body opening portion 2012 is provided with an outer cover 2012a (for example, composed of a light transmissive member such as a colorless or colored transparent plastic).

In addition, a bracket 2014 is installed near the top corners of the body sidewalls 2013 of the body 2010, and an upper end of four hanging rods 2019 that runs down the reservoir 2020 is coupled to the bracket 2014. It is fixed.

(Water tank)

14 to 16, the reservoir 2020 is accommodated in the body 2010. The reservoir 2020 has a cup shape with the ceiling open and the bottom closed, and the lower end of the rod 2019 hanging on the bracket 24 installed in the tank cylinder 2023 is fixed to the hanging rod 2019. It is lifted up by.

The tank cover 2021 is provided in the upper flange shape (like the periphery of the ceiling surface opening part) of the water tank 2020 in an inner flange shape. That is, the water tank cover 2021 is ring-shaped, and the clothes are introduced or taken out through the water tank opening 2022 of the ring.

And, the hood 2015 which connected the body opening part 2012 of the body 2010 and the water tank opening part 2022 of the water tank 2020 is provided. Since the hood 2015 is flexible or elastic, it deforms following the inclination of the reservoir 2020.

(Washing tank)

The washing tank 2030 is a "washing and dehydration tank" for providing the laundry, rinsing and dehydration of the put clothes, and a "washing and dehydration and drying tank" for providing the washing, rinsing, dehydration and drying of the put clothing. It is also called. The washing tub 2030 is disposed freely in the reservoir 2020.

The washing tub 2030 has a cup shape having a washing cylinder portion 2033 in which the ceiling surface is opened and the bottom thereof is closed, and the washing cylinder portion 2033 has a plurality of water passage holes for dehydration (hereinafter referred to as "dehydration holes"). 2034 is formed, and a balancer 2032 is provided around the ceiling surface opening 2031. Therefore, the range enclosed by the inner periphery of the balancer 2032 is provided as an opening for injecting or taking out clothes.

(Pulsator)

The pulsator 2040 is arrange | positioned rotatably in the inner side (in the tank) of the bottom face 2036 of the washing tank 2030. As shown in FIG. Wings 2040b are formed on the upper surface of the base 2040a of the pulsator 2040, and the clothes and the injected water are efficiently stirred. The lower surface of the base 2040a of the pulsator 2040 is provided with a plurality of vanes 2041 in a substantially radial direction, and a round annular back cover 2042 connecting them at the lower ends of the plurality of vanes 2041. Is installed. Therefore, between the lower surface of the base 2040a and the upper surface of the rear cover 2042, a plurality of roughly rectangular rod-shaped spaces (hereinafter referred to as "acceleration flow paths") 2043 partitioned by a pair of wings 2041 are formed. have.

Further, a round annular gap (hereinafter referred to as a "suction port") 2045 is formed between the inner circumference of the round annular plate 2042 and the drive shaft 2044 of the pulsator 2040, and the washing tank 2030 is formed. An opening (hereinafter referred to as a "circulation port") 2035 is formed in the bottom surface 2036 of the suction hole 2045.

Therefore, when the pulsator 2040 is rotated in the water, the water in the acceleration flow path 2043 is splashed outward in the radial direction by the centrifugal force, so that the water stored in the bottom of the reservoir 2020 is circulated. It passes through the sphere 2035 and the suction port 2045, and is sucked into the acceleration flow path 2043. At this time, since the acceleration flow path 2043 becomes a rotation flow path by the round annular plate 2042, and there is no leakage from the lower part of the blade 2041, the normal pulsator pump without the round annular plate 2042 is performed. Better pump performance.

(Circulation channel)

On the inner surface side of the washing cylinder portion 2033 of the washing tub 2030, a circulation channel 2050 having a predetermined width (same as the distance in the radial direction) is a bottom surface 2036. It is formed in the vertical direction (up and down direction in a figure) from to an outline upper end. The circulation channel 2050 is surrounded by a part of the washing cylinder 2033 and the circulation channel wall 2053, and the upper end portion is blocked by the top cover portion 2051, and the bottom surface 2036 of the washing tank 2030. An opening (hereinafter referred to as "discharge outlet") 2052 is formed between the circulation channel walls 2053. In addition, although the circulation channel 2050 is shown arrange | positioned three places in the circumferential direction, it does not limit the quantity.

Moreover, the casing 2060 is provided in the range except the circulation channel 2050 of the bottom surface 2036 of the washing tank 2030. That is, in the casing 2060, the outer circumference 2061 is connected to the washing cylinder portion 2033 and the circulation channel wall 2053, and the pulsator 2040 is rotatably housed in the inner circumference opening 2062. Since the gap 2063 between the inner circumference of the inner circumference opening 2062 and the outer circumference 2046 of the pulsator 2040 is narrow, when the pulsator 2040 is rotated, the water stored in the bottom of the reservoir 2020 is circulated. It passes through the sphere 2035 and the suction port 2045, is sucked into the acceleration flow path 2043, and passes through the discharge port 2052 and flows into the circulation channel 2050.

Therefore, the pump chamber is formed by the lower surface of the pulsator 2040, the blade 2041, the round annular plate 2042, and the casing 2060.

In addition, according to the outer periphery 2046 of the pulsator 2040, a round annular protrusion (precisely divided by a plurality of wings 2041, on the lower surface thereof, a plurality of arc-shaped protrusions) 2047. Is installed. For this reason, the flow which flowed along the lower surface of the pulsator 2040 in the acceleration flow path 2043 is bent downward by the protrusion 2047 at the outer periphery 2046.

The lower edge of the ledge 2047 is provided on the pulsator 2040 and the upper edge of the discharge port 2052 of the circulation channel 2050 (the same as the lower surface of the circulation channel wall 2053 at the discharge port 2052) ( 2054). For this reason, the water ejected from the acceleration flow path 2043 by the rotation of the pulsator 2040 is a cross section of the discharge port 2052 (same as the inner circumferential surface of the circulation channel wall 2053 at the discharge port 2052) (2055). There is no conflict directly.

Therefore, the water jetted from the acceleration flow path 2043 does not intrude into the washing tank 2030 from the gap 2056 between the end face 2055 of the discharge port 2052 and the outer circumference 2046 of the pulsator 2040. Difficult)

In addition, in the range in which the circulation flow path 2050 of the washing cylinder portion 2033 is formed, a plurality of through holes (hereinafter referred to as "spray holes") 2070a, 2070b, 2070c, and 2070d (hereinafter referred to as "spraying" Hole 2070 "may be referred to).

Since the inner diameter of the injection hole 2070 is smaller as it is closer to the discharge port 2052, which is the lower end of the circulation flow path, the force of the water flow ejected from the injection hole 2070d close to the upper end of the washing tank 2030 is weakened. There is no work. That is, since the washing water is sprayed with force toward the range where the washing water of the water tank 2020 is splashed, the corresponding range of the water tank 2020 is cleaned.

In addition, although four injection holes 2070 were formed, it does not limit the quantity.

(Rotary motor)

A common rotary motor 2080 for rotating driving the washing tub 2030 and the pulsator 2040 is provided on the bottom surface 2026 of the reservoir 2020. Moreover, rotation distribution means (not shown) which distributes rotation of the rotation motor 2080 to the pulsator 2040 or the washing tank 2030 is provided.

The rotation motor 2080 and the rotation distribution means perform predetermined rotations / stops and distributions in the washing stroke and the dehydrating stroke (or drying stroke), respectively, by the command of the control means.

The water supply mechanism has a water supply path whose one end is led out of the body 2010 and connected to an external tap water, and a water supply valve provided in the middle of the water supply path to open and close the flow of water. In addition, a drain port is formed on the bottom of the reservoir 2020, and a drain hose is connected to the drain port. Moreover, the drain valve which opens and closes a flow of water is provided in the drain port or the drain hose (all are not shown).

(Spray effect of washing water)

As described above, since the washing machine 2100 is sprayed toward the water tank cylindrical portion 2023 of the water tank 2020 by the rotation of the pulsator 2040, a separate pump means is used. The inner surface of the water tank cylindrical part 2023 is wash | cleaned without providing. In particular, since the washing water is sprayed even in a range higher than the surface of the washing water, dirt by the splash can be washed.

[2nd Embodiment 2: Washing Machine]

18 to 20 illustrate a washing machine according to Embodiment 2 of the present invention, FIG. 18 is a sectional view viewed from the side, FIG. 19 is an enlarged sectional view (spring from the side) of the injection hole, and FIG. 20 is a An enlarged sectional view (spring on the side). In FIG. 18, the washing machine 2200 installs a microbubble (microbubble) generating mechanism 2090 in the injection hole 2070 of the washing machine 2100 described in Embodiment 1, and holds the water tank 2020. It is free to tilt.

That is, the reservoir 2020 is hung by the front side hanging rod 2019a and the rear side hanging rod 2019b, and the rear side hanging rod 2019b is disposed on the front side (left side of the drawing). The hanging rod lifting means 2210 (installed in the bracket 2014) is connected to the upper end. Thus, when the hanging rod pulling means 2210 pulls up the rear hanging rod 2019b, the reservoir 2020 is inclined toward the front side. Instead of the hanging rod pulling means 2210, a hanging rod lowering means (installed in the bracket 24) may be connected to the lower end of the rear hanging rod 2019b.

(Fine bubble (micro bubble) generation mechanism)

In Fig. 19, an ejector type micro bubble (micro bubble) generation mechanism 2090 is provided in the injection hole 2070. The microbubble generating mechanism 2090 is opened in the circulation channel 2050, and the rear end of the nozzle portion 2091 and the nozzle portion 2091, the inner diameter of which narrows toward the outer surface side (same as the reservoir 2020 side). Next to the throat portion 2092 having the narrowest inner diameter, the diffuser portion 2093 which is connected to the rear end of the throat portion 2092 and widens the inner diameter toward the outer surface, and the rear end of the nozzle portion 2091 (diffuser portion 2093). The annular disclet 2094 formed at the beginning of the disc), the annular air passage 2095 surrounding the outer periphery of the disclet 2094, and the annular air passage 2095 to communicate with each other. It is formed of the air supply air passage 2096 opened near the ceiling surface of the 2030.

In addition, in FIG. 19, the fine bubble generation mechanism 2090 is accommodated in the injection hole 2070 (same as the inside of the plate | board thickness of the washing cylinder part 2033 of the washing tank 2030), and the air supply air path 2096 is Although formed in the plate | board thickness of the washing | cleaning cylinder part 2033, this invention is not limited to this, A part of the fine bubble generation mechanism 2090 protrudes from the injection hole 2070, or the air supply air path 2096 is The tubular body may be disposed outside the thickness of the washing cylinder 2033 (for example, in the circulation water channel 2050).

(Spray effect of washing water)

Therefore, since the washing water discharged by the rotation of the pulsator 2040 is pressurized while passing through the nozzle unit 2091 and is depressurized by the diffuser unit 2093, the atmosphere is discharged by the ejector effect from the discharge 2094. Aspirated. Then, while passing through the diffuser portion 2093, fine bubbles (micro bubbles) are generated, and the washing water including the fine bubbles (micro bubbles) is sprayed toward the reservoir 2020.

Therefore, the inner surface of the water tank 2020 is wash | cleaned by the high washing | cleaning property by a micro bubble (micro bubble). In addition, since the fine bubbles (micro bubbles) rise in the washing water, the outer surface of the washing tank 2030 is also washed by the rising fine bubbles (micro bubbles).

In addition, since the washing machine 2200a is inclined, the raised fine bubbles (micro bubbles) collide with the inclined outer surface of the inclined reservoir 2020, so that washing of the outer surface of the reservoir 2020 is promoted.

(Air supply stove)

In FIG. 20A, a part of the fine bubble generating mechanism 2090a is disposed in the circulation flow path 2050. That is, the nozzle part and the throat part which comprise an ejector protrude into the circulation channel 2050, and the diffuser part is accommodated in the plate | board thickness of the washing cylinder part 2033. As shown in FIG. The air supply passage 2096a is formed of a tubular body disposed in the circulation passage 2050, and the tip thereof protrudes from the top cover portion 2051 to reach the vicinity of the balancer 2032. Therefore, since the tip of the air supply path 2096a is covered by the balancer 2032 in a cover state, foreign matter such as seams is difficult to invade into the air supply path 2096a.

In FIGS. 20B and 20C, the fine bubble generating mechanisms 2090b and 2090c are formed of tubular bodies in which the air supply passages 2096b and 96c are disposed in the circulation channel 2050, and the tip thereof is L. FIG. It is bent in a U-shape and a U-shape. Therefore, foreign matters such as seams are difficult to penetrate into the air supply paths 2096b and 2096c.

(Operation method of pulsator)

It is a correlation diagram explaining the characteristic of the pulsator of the washing machine concerning 2 of Embodiment 2 of this invention. In FIG. 21, the vertical axis represents the discharge flow rate of the pulsator 2040, and the horizontal axis represents the rotation in the other direction after the rotation of one direction with respect to the rotation time T1 at which the pulsator 2040 is rotating in one direction. The ratio of the stop time (T2) to starting. That is, when the ratio exceeds 0.6 (T1 / T2> 0.6), the discharge flow rate rapidly decreases. Therefore, it is preferable to shorten the stop time T2 so that the ratio may be "0.6 or less (T1 / T2≤0.6)" and change the rotation direction quickly. The pulsator 2040 is the same as that in 1 of the second embodiment.

[1 of Embodiment 3]

It is sectional drawing seen from the side explaining the labyrinth of the washing machine concerning 1 of Embodiment 3 of this invention. In addition, in order to understand easily, since each structural member in a figure is shown typically, the dimension is not accurate. In particular, the thickness of the member formed by the thin plate is exaggerated, and the gap between the structural members is exaggerated. In addition, the same code | symbol is attached | subjected to this same part in FIGS. 22-33, and description of a part is abbreviate | omitted.

In FIG. 22 (refer FIG. 28 for some details), the washing machine 3100 performs a series of washing strokes, rinsing strokes, dewatering strokes and drying strokes. In addition, a washing stroke and a rinse stroke may be collectively called a "washing stroke."

The washing machine 3100 includes a body, a reservoir (not shown in the drawing) housed in the body, a washing tank 3010 rotatably disposed in the storage tank, and a pulsator 3040 rotatably disposed in the washing tank 3010. And an casing 3020 provided in the washing tub 3010 to freely surround the pulsator 3040 and an opening formed in the washing tub 3010 and formed in the casing 3020 (hereinafter referred to as an inlet). It has a circulation channel 3030 in communication with 3070.

(Washing tank)

The washing tank 3010 is a "washing and dehydration tank" for providing the laundry, rinsing and dehydration of the put clothes, and a "washing and dehydration and drying tank" for providing the washing, rinsing, dehydration and drying of the put clothing. It is called. The washing tank 3010 is disposed freely in a water tank (not shown).

The washing tub 3010 has a cup shape in which the ceiling surface is opened, and a bottom opening 3011 opened in a circular shape at the center of the bottom surface 3012 is formed, and both are smoothed between the bottom surface 3012 and the cylindrical side surface 3014. An inclined surface 3013 having a rough cone shape is connected. In addition, a plurality of water passages (not shown) are formed in the side surface 3014 for circulation of the washing water in the washing stroke and for blowing of the washing water in the dewatering stroke.

(Pulsator)

The pulsator 3040 is arrange | positioned rotatably in the inner side (in tank) of the bottom face 3012 of the washing tank 3010. As shown in FIG. Wings 3040a are formed on the upper surface of the base 3040b of the pulsator 3040 to efficiently stir the clothes and the injected water. On the lower surface of the base 3040b, a plurality of rear wings are provided in an approximately radial direction, and a round annular plate (hereinafter referred to as a "back cover") 3042 connecting them is provided at the lower ends of the plurality of rear wings. Therefore, between the lower surface of the base 3040b and the upper surface of the back cover 3042, a plurality of roughly rectangular bar-shaped spaces (hereinafter referred to as "acceleration flow paths") 3043 partitioned by a pair of rear wings are formed.

Further, a circular annular gap (hereinafter referred to as a "suction port") 3045 is formed between the inner circumference 3042a of the rear cover 3042 and the drive shaft 3044 of the pulsator 3040, and the suction port ( 3045 is roughly overlapped in plan view with the bottom opening 3011 formed in the bottom 3012 of the washing tub 3010, and both are in communication.

Therefore, when the pulsator 3040 is rotated in the water, the water in the acceleration flow path 3043 is blown outward in the radial direction by the centrifugal force, so that the bottom 3012 of the washing tank 3010 is underneath. The stored water passes through the bottom opening 3011 and the suction port 3045 to be sucked into the acceleration flow path 3043. At this time, since a gap is not formed between the rear wing 3041 of the pulsator 3040 and the bottom face 3012 of the washing tub 3010, water does not leak and pump performance (same as suction / discharge performance) This is excellent.

In addition, the outer circumferential end surface 3041b which connects the outer circumferential end surface 3041b of the rear wing 3041 to the back surface of the base 3040b, and encloses the predetermined range near the base 3040b, and the surface of the base 3040b has a wing | blade ( The outer peripheral wall 3060 which connects the outer periphery of 3040a, and protrudes upward along an outer periphery is provided, respectively. Therefore, in the washing stroke, the water flow blown out from the acceleration flow path 3043 by the rotation of the pulsator 3040 is directed downwardly on the inner circumferential surface 3050a of the rear outer circumferential wall 3050, In the washing tank 3010, the washing water stirred by the rotation of the blade 3040a of the pulsator 3040 is directed upwardly from the inner circumferential surface 3060a of the outer circumferential wall 3060.

In the outer circumferential end surface 3041b of the rear wing 3041, a range lower than the rear outer circumferential wall 3050 is notched, and the rear wing notch portion 3041c is formed. That is, the outer periphery (henceforth "notch side end surface 3041d") of the range which follows the rear wing notch part 3041c enters one step more than the outer periphery end surface 3041b (it is located in the figure on the left side).

(Circulation channel)

On the inner surface side of the side surface 3014 of the washing tub 3010, a circulation channel 3030 of a predetermined width (same as the distance in the circumferential direction) is outlined from the bottom surface 3012 at a predetermined thickness (same as the distance in the radial direction). The upper end is formed in the vertical direction (up and down direction in the figure).

The circulation channel 3030 is surrounded by a part of the bottom surface 3012 of the washing tub 3010 and the circulation channel wall 3032, and the upper end portion is blocked by the top cover portion 3034, and the circulation channel wall 3032 is The injection hole 3033 penetrated is formed. The lower end of the circulation channel wall 3032 is connected to the upper end of the casing 3020 (limited to the position of the inlet port 3070) through the communication channel wall 3031.

(Labels (1))

A cylindrical fixed side index wall 3021 is formed to protrude upward along the inner circumference of the casing 3020. Further, at the lower end of the casing 3020, a round annular fixed side inner flange 3022 protruding toward the inner circumferential side is formed, and a cylindrical fixed side protruding upward along the inner circumference of the fixed side inner flange 3022. An index wall 3021 is formed.

On the other hand, on the lower surface 3050c of the rear outer circumferential wall 3050 provided in the pulsator 3040, a moving side index groove 3051 which is a round annular groove is formed.

Then, when the fixed side water stop wall 3021 is free to penetrate into the moving side water stop groove 3051, and a predetermined minute gap is formed between the fixed side water stop walls 3021, the labyrinth which forms an exponential property by both (hereinafter, "Called the labyrinth 1" is formed.

(Labels (2))

A fixed side water stop groove 3023 is formed which is recessed downward in a circular ring shape along the inner circumference of the casing 3020.

On the other hand, a flange 3061 protruding outward is formed at an upper end of the outer circumferential wall 3060 provided in the pulsator 3040, and a cylindrical moving side index wall 3062 protruding downward along the outer circumference of the flange 3061. ) Is formed.

Then, when the moving side index wall 3062 is free to penetrate into the fixed side index groove 3023, and a predetermined small gap is formed between the two sides when the moving side index wall 3030 is invaded, the labyrinth which forms exponentiality by both (hereinafter, "Called the labyrinth 2" is formed.

In addition, the outer circumferential surface 3050b of the rear outer circumferential wall 3050 and the outer circumferential surface 3060b of the outer circumferential wall 3060 form the same surface, and are opposed to the inner circumferential surface 3020a of the casing 3020 through a predetermined minute spacing. Then, these also form a gap forming exponentialness.

Therefore, since the washing machine 3100 includes the labyrinth 1 and the labyrinth 2, the washing water discharged by the rotation of the pulsator 3040 is circulated in the circulation water without any amount of dripping or dripping ( 3030). Therefore, the pump up performance of the pulsator 3040 improves.

The present invention is not limited to the washing machine 3100 having both the labyrinth 1 and the labyrinth 2, but may be provided with any one.

In addition, unlike the bottom part 4022 of the washing-and-dehydrating tank 4021, the bottom wall 4022a of the washing-and-dehydrating tank 4021 is the part which comprises the floor of the washing space in the washing-and-dehydrating tank 4021. As shown in FIG. .

In addition, although the pulsator 4100 rotates relatively with respect to the washing and dehydrating tank 4021 during a washing | cleaning process, by setting it as the said structure, the upper surface of the upper surface part 4113 of the base part 4110 is always rotated. The upper surface of the bottom wall 4022a of the washing / dehydrating tank 4021 can be kept in the same surface state.

Further, one outer wall portion 4112a is formed outside the main wall portion 4112 of the pulsator 4100 so as to extend downward from the upper surface portion 4113. Thereby, the circumferential wall part of the pulsator 4100 becomes two pieces structure, and the intensity | strength of the pulsator 4100 is improving.

In the blade 4120 of the pulsator 4100, the portion corresponding to the lower side of the inclined surface 4110a is located at a position lower than the upper surface of the bottom wall 4022a of the washing and dewatering tank 4021, but the inclined surface 4110a. The part corresponding to the higher side of) is projected upward from the upper surface of the bottom wall 4022a. And the inclined surface 4121 which inclined the cross section of the side which protruded upward (cross section of the longitudinal direction of the blade 4120 of the pulsator 4100 in the longitudinal direction of the base part 4110) with the inclination toward the inside. ), And the clearance gap with the channel forming member 4041a provided in the main wall 4023 of the washing-and-dehydrating tank 4021 is more than a predetermined distance. In this example, the clearance between the highest position of the inclined surface 4121 and the channel forming member 4041a is set to, for example, 25 mm or more.

The operation in the above configuration will be described. In addition, in the following operation | movement description, only the operation | movement which is directly concerning this invention, ie, a washing process, is demonstrated, and description of other process is abbreviate | omitted.

In the washing process, when the pulsator 4100 is rotated by the motor 4037, the laundry placed on the pulsator 4100 moves up and down by the action of the inclined surface 4110a of the pulsator 4100. At this time, in the conventional structure, the height of the gap between the washing and dehydrating tank 4021 and the pulsator 4100 is changed by the rotation of the pulsator 4100, whereby the laundry, such as thin socks, is formed in the gap. Although this bleeding phenomenon occurs, in the structure of this example, the height of the gap portion does not change due to the rotation of the pulsator 4100, so that the bleeding of the laundry can be prevented.

That is, in the structure of this example, each height position on the boundary portion between the washing and dehydrating tank 4021 and the pulsator 4100, that is, the upper surface of the bottom wall 4022a of the washing and dehydrating tank 4021, and the pulsator 4100 Since the upper surface of the upper surface portion 4113 of the base portion 4110 of () is always the same surface during the pulsator rotation, laundry can be prevented from entering the gap. In addition, even if a sock or a blouse cuff enters the gap, for example, the laundry is pushed upward by the upward force acting on the other part of the laundry, and the part of the gap enters the gap from the gap. Exit Therefore, as in the conventional structure, it can be prevented from being further inserted into the gap.

In this way, it is possible to prevent the laundry from being picked up or interrupted, so that an increase in the load torque of the motor 4037 driving the pulsator 4100 and damage to the laundry can be prevented.

Moreover, since the channel forming member 4041a protrudes inward and is provided in the circumferential wall 4023 of the washing-and-dehydrating tank 4021, the base is formed at the wing 4120 of the pulsator 4100. Although the gap becomes narrow when the cross section of the side with the high inclination of the portion 4110 comes in a position facing the channel forming member 4041a, the inclined surface 4121 is provided in the corresponding cross section of the blade 4120 of the pulsator 4100. Therefore, the laundry can be prevented from entering.

In addition, since the circumferential wall portion 4112 of the pulsator 4100 has a two-piece structure, the strength of the pulsator 4100 can be increased, and the durability can be improved.

In addition, the pulsator 4100 may be an integrally molded product in which the base portion 4110 and the blade 4120 are integrally molded, and the base portion 4110 and the blade 4120 are formed as separate members, The assembled assembly may be sufficient. When the base portion 4110 and the blade 4120 are integrally molded with a resin or the like, the cost can be reduced in terms of the number of parts and the assembly workability. On the other hand, if the base part 4110 and the blade 4120 are made into separate components, the member can be appropriately selected from the viewpoint of drying performance, such as a thermally conductive material (for example, stainless steel) or designability. have.
