Problems to be solved by the invention

[0004] The conventional washing machine is mainly designed to wash clothes by applying a swirling force to water in a washing tub by a pulsator and thereby stirring the clothes. Therefore, an appropriate amount of water is required for appropriate clothing. If the amount of water is small, the clothing directly collides with the convex rib of the pulsator, as described in the above-mentioned patent document, and there is a problem that the clothing is damaged due to the impact and friction of the surface at that time.

In these drying washing machines, a plurality of hot air holes are provided on the surface of the pulsator, and the pulsator is rotated without water in the rotating tub. There are problems such as wrinkling, wrinkling due to twisting of clothes due to the difference in rotation speed between the vicinity of the rotation axis and the outer periphery, and the problem that drying takes time.

[0006] Therefore, it is an object of the present invention to provide a washing machine capable of washing clothes by tapping and washing the clothes by vibrating the clothes up and down by rotating the pulsator. [0007] Another object of the present invention is to provide a washing machine having a drying function, in which the clothes are vibrated up and down by rotating the pulsator, so that the clothes can be washed and good drying efficiency can be obtained. It is in.

Means for solving the problem

The protruding portion has a shape that gradually protrudes from the center of rotation in the outer circumferential direction, and when a cross-sectional shape of a circumference departed from the center by a predetermined position is developed, the surface of the pulsator gradually increases from the protruding portion. The wave shape reaches the valley and gradually reaches the ridge from the valley.

The invention's effect

[0009] According to the present invention, it is possible to improve the washing efficiency or the drying efficiency of clothing by easily applying vertical vibration to clothing put into the rotating tub.

Other objects, features and advantages of the present invention will become apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

[0010] The preferred embodiment described here relates to an electric washing machine or a drying washing machine provided with a rotating tub in which rotating shafts are arranged vertically, and the feature thereof is that the rotating shaft of the rotating tub is provided. A pulsator having a substantially circular upper surface is provided on the upper surface of the pulsator, and the upper surface of the pulsator is composed of a plurality of raised portions formed radially from the rotation axis and a valley formed between the raised portions. By making the protruding portion gradually protrude in the outer circumferential direction from the rotation axis, the surface of the pulsator gradually becomes a valley from the protuberance when a circumferential cross-sectional shape separated from the rotation axis by a predetermined position is developed. The point is that a wave shape from the valley to the uplift is gradually provided.

[0011] According to the electric washing machine or the electric drying washing machine according to the best mode, the clothes to be thrown into the rotating tub can be easily subjected to the vertical vibration to improve the washing efficiency or the drying efficiency of the clothes. Can be improved. According to this pulsator, the same operation and effect can be obtained even with a pulsator of an electric washing machine having no dewatering function.

Hereinafter, with reference to FIG. 1 to FIG. 64, the electric washing machine or the electric washing machine according to this embodiment will be described. The drying machine will be described. FIGS. 1 to 3 show a first embodiment in which the present invention is applied to an electric washing machine, FIGS. 4 to 6 show a second embodiment in which the present invention is applied to a washing machine, and FIGS. 64 shows another embodiment of the pulsator applied to these electric washing machines or electric drying washing machines. Note that the same parts and functional parts are denoted by the same reference numerals, and redundant description will be omitted.

(First Embodiment)

FIGS. 1 to 3 show a first embodiment in which this pulsator is applied to an electric washing machine provided with a rotating tub having a rotating shaft in a vertical direction in a housing.

First, a schematic structure of the electric washing machine will be described with reference to FIG. FIG. 1 is a schematic composition diagram, in which (a) is a sectional view of an electric washing machine, (b) is a perspective view of a pulsator, and (c) is a developed sectional view of the pulsator.

The electric washing machine 1 includes a box-shaped casing 10 and an upper cover 20 that covers an upper part of the casing 10. The casing 10 includes a lower casing 11 of a resin molded product constituting the bottom of the casing 10 and an upper casing 12 made of a steel plate constituting the upper part of the casing 10. Hanging rod mounting portions 13 are provided at the upper four corners of the housing 10, and the housing 10 is mounted on the housing 10 so that the washing tub 30 is supported at four points via the hanging rods 14 attached to the hanging rod mounting portions 13. It is attached.

[0015] The washing tub 30 is a container opened to the upper part. A rotating tub 40 is disposed in the washing tub 30, and the rotating tub 40 and a motor 31 provided at a lower part of the washing tub 30 are connected to each other. It is attached via a rotating shaft 32 of a motor 31. The rotary tub 40 is a cylindrical container having an open top, and has a plurality of dehydration holes 41 formed therearound. The tip of the rotating shaft 32 of the motor 31 is exposed at the bottom of the rotating tank 40, and the pulsator 100 is attached to the tip. Here, the pulsator 100 is directly connected to the rotating shaft 32 of the motor 31, and the rotating tub 40 can be connected to the rotating shaft 32 of the motor 31 or set free by a clutch mechanism (not shown).

[0016] Therefore, according to the washing machine 1, by rotating the pulsator 100 independently or in conjunction with the rotary tub 40, the clothes put in the rotary tub 40 can be washed. By rotating the rotary tub 40 at high speed, dehydration can be performed.

[0017] On the other hand, the upper cover 20 is provided with clothing to fit the upper opening 42 of the rotating tub 40. An inlet 21 is provided, and a lid 22 is provided above the inlet 21. Further, an operation panel section 23 is disposed in front of the lid 22. Note that a ring-shaped balancer 43 is attached to the upper opening portion 42.

One of the major features of the electric washing machine 1 is that a pulsator 100 that enables the clothes in the rotary tub 40 to be swung up and down to enable the clothes to be washed by tapping is adopted. The pulsator 100 has a substantially circular upper surface shape as shown in FIG. 2B, and its surface is formed between a plurality of raised portions 101 formed radially from the rotation axis P and the raised portions 101. And a valley 102 formed. In this embodiment, the laser includes two raised portions 101a and 101b formed with the rotation axis P of the pulsator 100 interposed therebetween, and two valleys B 102a and 102b formed between the raised portions 101. You.

The protruding portion 101 has a shape that gradually protrudes in the outer circumferential direction from the rotation axis P. When a cross-sectional shape at a position separated by a predetermined distance L1 from the rotation axis P is developed, the surface of the pulsator 100 (C) As shown in the figure, it gradually rises from valley 102a to ridge 101a, gradually descends from ridge 101a to valley 102b, and gradually rises again from valley 102b. As a result, it has a wave shape that reaches the raised portion 101b, and then gradually descends again from the raised portion 101b to the valley portion 102a.

The pulsator 100 has a size such that the entire bottom surface of the rotary tank 40 is substantially covered by the pulsator 100. Accordingly, the curved surface of the waveform constituting the upper surface of the pulsator 100 is arranged almost continuously on the inner wall surface of the rotary tank 40. Here, in this embodiment, in order to improve the fitting between the pulsator 100 and the rotary tub 40, a ring-shaped edge 44 is left on the outer periphery of the bottom of the rotary tub 40, and the inside of the edge 44 is The pulsator 100 is arranged in the pulsator receiver 45.

According to the pulsator 100, for example, clothing existing near the rotation axis P of the pulsator 100 moves outward from the vicinity of the rotation axis P due to the centrifugal force generated by the rotation of the pulsator 100. In the course of this movement, the clothing present on the pulsator 100 moves on the corrugated surface formed by the ridges 101 and the valleys 102 of the pulsator 100. That is, the garment tries to stop at that position due to the inertial force, and moves while sliding on the undulating surface of the pulsator 100. Looking at the movement of the clothing up and down, the clothing swings up and down. Take a moving motion. Here, the difference (step) L2 between the raised portion 101 and the valley portion 102 constituting the surface of the waveform of the pulsator 100 becomes smaller as it goes closer to the outer periphery in the vicinity of the rotation axis P. Therefore, looking at the vertical movement of the garment moving from the center of the pulsator 100 to the outer periphery due to the centrifugal force, the upward and downward movement gradually increases as the garment moves from the rotation axis P to the outer periphery. In addition, the clothing that increases the up-and-down movement moves due to the inner ring difference (difference between the circumference of the rotation axis P and the circumference of the outer circumference (speed difference)), that is, the clothing moves with the motion of reversing the clothing.

Then, the clothing that has reached the outer periphery rises on the inner wall surface of the rotating tub 40 by another clothing sent one after another, and moves again to the vicinity of the rotation axis P.

[0021] According to the washing machine 1, when the amount of water filled in the rotary tub 40 is small, the effect of the tap washing can be further obtained. Therefore, the amount of water can be reduced as compared with the conventional example in which the washing is performed by the stirring flow. In addition, since the clothes are vibrated up and down as in the case of tapping and the amplitude of the garment is gradually increased, the cleaning effect can be improved.

Next, the characteristics of this pulsator will be further described with reference to FIG. FIGS. 2A and 2B are schematic diagrams of the operation principle according to this embodiment, in which FIG. 2A is a perspective view in section of a rotating tub, and FIG. 2B is a graph showing a vibration operation of clothing.

In FIG. 2, in this embodiment, ridges 101 and valleys 102 formed on the upper surface of pulsator 100 are alternately arranged at equal intervals. In the drawings, the folded portions (ridges) of the ridges 101 and the valleys 102 are shown by straight lines for easy understanding. As a result, the ridge 101 and the valley 102 are symmetrical with respect to the rotation axis P, so that even when the pulsator 100 is rotated at a high speed, the rotation axis does not move.

[0024] In addition, as shown in Fig. (A), in this embodiment, the upper surface of the disk is turned up from a line (valley) passing through the rotation axis P, and a flat inclined surface gradually rising toward both sides. And Therefore, in this embodiment, the two semicircular surfaces forming the upper surface of the pulsator 100 have a shape that is folded back in a V-shape.

That is, the protruding portion 101 has a shape that gradually protrudes from the rotation axis P in the outer circumferential direction, and the valley portion 102 has a shape that extends substantially horizontally from the rotation axis P to the outer circumference. Here, the valleys 102 are illustrated at an acute angle in the drawing, but are continuous with small rounds or flat surfaces. Further, in this embodiment, the valley 102 may have a shape that is gradually raised in the outer circumferential direction of the force formed horizontally. What is important here is the step L2 between the ridge 101 and the valley 102 at a point equidistant from the rotation axis P.

In this embodiment, the washing power is improved by vibrating the clothes up and down by the rotation of the pulsator 100, so that the level difference L2 substantially becomes the vibration width L2 of the clothes. Accordingly, the upper surface of the pulsator 100 is formed of a curved surface having a waveform that gradually increases the amplitude width L2 from the rotation axis P toward the outer periphery.

[0027] Experimentally examining the relationship between the angle of inclination of the inclined surface 角度 (the angle with respect to the rotation direction of the panolease) and the vertical movement of the laundry and the cloth entanglement, the vertical movement of the laundry is expressed as the inclination. It increased in proportion to the inclination angle of the surface, peaked at a certain angle, and decreased after that. From this, it was found that there was an optimum tilt angle. This is because if the inclination angle is too large, the laundry will be pushed by the inclined surface, making it difficult for the laundry to slip on the pulsator surface, and making it difficult to move above the inclined surface. According to the experimental results, the inclination angle Θ is preferably 15 to 25 °, and the height difference of the inclined surface is about 0.13 to 0.22 times the pulsator diameter.

[0028] On the other hand, according to the experimental results, the cloth entanglement suddenly starts to increase more than the inclination angle at which the vertical movement of the laundry starts to decrease. This is because if the angle of inclination is too large, the laundry will be in a dumpling shape at the valley of the inclined surface that slides on the surface of the pulsator 100, and the laundry will roll.

Next, the movement of the clothes to be washed will be further described with reference to FIG.

First, in FIG. 2 (a), the clothing put into the rotating casserole 40 moves in the outer circumferential direction from the rotation axis P of the pulsator 100 as shown by the arrow, and Along the rotation axis P of the rotary tub 40, further down along the rotation axis P, and again along the pulsator 100 along a trajectory moving from the rotation axis P to the outer peripheral direction.

That is, the clothing existing near the rotation axis P of the pulsator 100 moves from the vicinity of the rotation axis P to the outer periphery due to the centrifugal force generated by the rotation of the pulsator 100 and reaches the inner wall surface of the rotary tank 40. . Since the clothing near the rotation axis P becomes empty due to the movement of the clothing, the next clothing is supplied near the rotation axis P from above. Clothes that have moved to the outer periphery first will be And rises along the inner wall. Then, the raised garment is sent out to the vicinity of the upper rotation axis P and further descends along the rotation axis P. Thus, the clothing circulates by the rotation of the pulsator 100.

[0032] The major feature of this embodiment is that, in the process of moving from the rotation axis P of the pulsator 100 in the outer peripheral direction, the garment force existing on the pulsator 100 and the bulge 101 and the valley 102 of the pulsator 100 The point is that the amplitude in the vertical direction gradually increases by sliding while moving on the surface of the waveform formed by. That is, the garment located on the surface of the pulsator 100 tries to stop at that position due to the inertial force, and moves while sliding on the undulating surface of the pulsator 100. Looking up and down, clothing moves up and down along the shape of the waveform.

Here, on the surface of the waveform of the pulsator 100, the difference between the raised portion 101 and the valley portion 102 (step L2) increases nearer the rotation axis P and becomes smaller toward the outer periphery. Therefore, looking at the vertical movement of the clothing moving from the rotation axis P of the pulsator 100 to the outer circumference due to the centrifugal force, the vertical movement gradually increases as the clothing moves from the rotation axis to the outer circumference.

(B) schematically shows the movement of the garment in which the amplitude width L2 in the vertical direction is gradually increased. The X axis shows the distance from the center position, and the Y axis shows the upper and lower amplitude width L2 (height) of the clothing. Q1 indicates one rotation of the pulsator 100. As is clear from the figure, the garment near the rotation axis P initially has a small amplitude width L2, but the amplitude width L2 increases as it goes in the outer circumferential direction due to centrifugal force, and the outer peripheral end of the pulsator 100 The clothing that has reached the position rises along the inner wall surface of the rotating tub 40, and repeats a circulation cycle reaching the vicinity of the rotation axis P again.

Also, the clothing that increases this vertical movement moves with the rotational motion, that is, the motion of reversing the clothing, due to the inner ring difference between the outer circumference and the inner circumference. Therefore, the clothes circulating in the rotating tub 40 repeatedly perform the washing in which the up-and-down movement is gradually increased while being inverted, so that the same effect can be obtained as in the case of performing the tap washing.

[0036] In particular, in the conventional pulsator, since the convex ribs protrude from the flat upper surface, there is a problem that the clothing hits the convex ribs to reduce the durability of the clothing. However, in this embodiment, Since the upper surface of the pulsator has a gentle curved shape, the clothing moves so as to slide on the upper surface, so that the durability of the clothing can be reduced. Further, in the conventional example, there is a problem that the clothes are twisted and entangled due to the inner ring difference, but in this embodiment, the force S can be reduced to alleviate this problem.

Next, with reference to FIG. 3, the external shape of the pulsator according to this embodiment will be further described. Fig. 3 is an external view of the pulsator, (a) is a perspective view, (b) is a front view, (c) is a top view, (d) is a right side view, and (e) is a transverse view. The plan view and the figure (f) are bottom views. The back view is omitted from the front view and the left view is omitted from the right view.

[0038] The pulsator 100 according to the present embodiment is a molded article formed by one molding die. In this embodiment, it is made of a resin material in order to reduce the weight. When formed of a resin material, in order to increase the strength of the center of rotation, a metal material may be attached to or integrally formed with the bearing 104 to which the rotating shaft 32 of the motor is attached.

In this embodiment, in order to reduce the material cost and reduce the weight, the wall pressure of the corrugated surface is reduced as shown in FIGS. If such a thin-walled structure is adopted, the strength is weakened. Therefore, a plurality of reinforcing ribs 103 are provided on the bottom side. The reinforcing rib 103 is formed in a cross shape at a position corresponding to the top of the ridge 101 and the bottom of the valley 102, and a plurality of ring-shaped reinforcing ribs are formed around the rotation axis! ^3. It can respond to the load applied from the upper surface. Since the pulsator 100 is a rotating body, the reinforcing ribs 103 are formed so as to be symmetrical about the rotation axis P.

As described above, the pulsator 100 according to this embodiment divides the upper surface by a line segment (valley portion 102) passing through the rotation axis P, and gradually raises both sides from the inclined surface formed. Bulge 101. Therefore, in the front view shown in FIG. (B), the top surface shape is almost V-shaped, and in the left and right side views shown in (d), it has an arc shape. Further, in this embodiment, the strength is increased by forming an edge 105 around the upper surface of the waveform.

[0041] The edge 105 is formed such that a plane portion of the upper surface is bent at a peripheral end to form a vertical surface. Further, in this embodiment, the lower portion of the edge portion 105 is formed to be horizontal, and the height (width) of the edge portion 105 is small in the valley portion 102 and the height (width) is large in the raised portion 101. What I'm wearing

As shown in FIG. 2A, the pulsator 101 is housed in a concave pulsator receiving portion 45 formed at the bottom of the rotary tank 40 and attached to the rotary shaft 32 of the motor 31. The gap between the pulsator receiver 45 and the pulsator 100 should be large enough that the edge 105 of the pulsator 100 does not come into contact with the inner wall surface of the pulsator receiver 45 and that no clothing or coins enter the gap. .

When the pulsator 100 is attached to the pulsator receiving portion 45, the pulsator 100 is formed at the top of the pulsator 100, that is, at the height of the outer peripheral portion of the raised portion 101, around the pulsator receiving portion 45. It is almost flush with the ring-shaped edge 44. For this reason, in the V-shaped portion, the inner wall 45a of the pulsator receiving portion 45 is exposed, and clothing is appropriately in contact with the exposed portion, so that an improvement in the cleaning effect can be expected.

As described above, according to this embodiment, the clothes can be vibrated up and down by the rotation of the pulsator 100, and the clothes can be washed in a manner similar to the knocking. In the above description, the cleaning effect can be obtained by reversing and rotating the pulsator 100 or the rotation of the rotating tub 40 and the pulsator, in which the movement of the clothes is explained by the one-way movement of the pulsator 100. Can be expected to improve.

(Second embodiment)

Next, with reference to FIG. 4 to FIG. 6, an electric drying washing machine according to a second embodiment capable of performing good clothing washing and clothing drying by applying vertical vibration of the clothing to the clothing will be described. explain.

First, with reference to FIG. 4, a schematic structure of the drying and washing machine according to the present embodiment will be described.

FIGS. 4A and 4B are schematic views, in which FIG. 4A is a cross-sectional view of the drying and washing machine, FIG. 4B is a perspective view of the pulsator, and FIG. 4C is a developed view of the pulsator.

This embodiment employs a pulsator 110 having a structure similar to that of the pulsator 100 employed in the first embodiment. However, this pulsator 110 is different from the pulsator 100 employed in the electric washing machine 1 in that a ventilation section 111 comprising a plurality of small holes is provided on the surface thereof.

First, the schematic structure of the drying and washing machine 5 will be described with reference to FIG. here In the following, points of difference in structure from the first embodiment will be described, and similar structural parts will be denoted by the same reference numerals, without redundant description. The drying and washing machine 5 has a washing tub 30 having a hot air circulation function. In this embodiment, a warm air circulation unit 50 is provided on the back side of the washing tub 30.

That is, the drying and washing machine 5 has a drying function in addition to washing clothes by blowing warm air into the washing tub 30. This structure will be further described. In FIG. 4, the electric drying and washing machine 5 includes a hot air duct 51 meandering up and down, and a shower water cooling / dehumidifier 52, a temperature sensor 53, a blower 54, and a heater 55 are provided in the hot air duct 51. I have.

[0049] The hot air duct 51 rises upward from the lower end of the washing tub 30 (first rising duct 51a), and descends near the upper end of the washing tub 30 (downward duct 51b). It communicates with the blower 54 provided below 30 (at a position adjacent to the motor 31).

The hot air duct 51 rises again from the blower 54 (a second rising duct 51c) and supplies hot air into the rotary tub 40 from the upper end of the washing tub 30.

An opening / closing lid 56 is provided at an upper open portion of the washing tub 30 to prevent hot air from leaking out of the washing tub 30.

As described above, in the present embodiment, once the warm air duct 51 is lifted up to near the upper part of the washing tub 30 via the first rising duct 51a and the lowering duct 51b, Water can be prevented from entering the blower 54.

[0052] Further, it is possible to arrange the shower water-cooled dehumidifier 52 using the first ascending duct 51a. The shower water-cooled dehumidifier 52 is provided above the first ascending duct 51a, and can cool and dehumidify hot air by spraying water in a shower. Further, temperature sensors 53 are provided above and below using the descending duct 51b. Further, a heater 55 is provided at the upper end of the second ascending duct 51c.

According to this structure, the air is warmed by the heater 55 and sprayed on the clothes in the washing tub 30, and the air is moistened from the ventilation holes 111 provided on the plurality of holes 41 of the washing tub 30 and the upper surface of the pulsator 110. Air is taken into the first ascending duct 51a, and the moist air is collected and dehumidified by the shower water-cooled dehumidifier 52. After that, the dried air is taken into the blower 54 through the descending duct 51b. Then, it can be supplied again to the heater 55 via the second ascending duct 51c.

As described above, as the pulsator employed in the drying and washing machine 5, the pulsator provided with the ventilation section 111 on the upper surface of the pulsator 100 of the first embodiment can be employed. The structure is shown in Fig. 4 (b), (c) and Fig.5. Fig. 5 is an external view of the pulsator, (a) is a perspective view, (b) is a front view, (c) is a top view, (d) is a right side view, and (e) is a transverse view. The plan view and (f) are bottom views. The back view is omitted because it is symmetrical with the front view, and the left side view is omitted with respect to the right side view.

The detailed structure is omitted because it is the same as the description of FIG. However, the ventilation section 111 is formed by arranging small small holes in a punching shape and forming a circular shape around the rotation axis P. The area of the ventilation section 111 is not limited to a circular shape. Details will be described later.

Next, with reference to FIG. 6, the movement of the clothes when the clothes are dried in the electric drying washing machine 5 according to this embodiment will be described in comparison with a conventional example. FIG. 6 illustrates the movement of the clothes in the rotating tub 40 during the drying of the clothes. A-1 to A-3 show the conventional examples, and B-1 to B-4 show the examples of this embodiment. Show the movement of clothing.

First, in the conventional electric drying washing machine, the clothes are dried by draining water from the washing tub 30 and rotating the pulsator while supplying the hot air circulating unit 50 hot air. In such a conventional example, since a radially projecting rib is provided on the upper surface of the disk of the pulsator, the rib is dried by rubbing the laundry or deforming the laundry. For this reason, in the conventional example, as shown in A-1, the clothes move toward the outer periphery by the centrifugal force, but the force in the rotation direction by the convex rib is stronger. Then, as shown in A-2, the clothes change on the pulsator while the clothes rotate in the rotation direction. Further, as shown in A-3, the clothes were uniformly spread on the pulsator, and the twisting of the clothes occurred due to the difference in the rotation speed between the inner circumference and the outer circumference. Therefore, in the conventional pulsator, the clothes tend to be in the shape of a dumpling, and fabric entanglement tends to occur. Moreover, due to the twisting phenomenon, problems remain in wrinkling, drying finish, drying time, and the like.

On the other hand, according to the electric washer / dryer 5, the problem of the conventional example can be reduced by the movement of the garment in the same manner as in the above-described washing. That is, in this embodiment, Since the upper surface of the lucator 110 is formed as a gently continuous smooth surface, the rotation of the pulsator 110 causes the centrifugal force to cause the clothes to slide on the pulsator 110 toward the outer periphery as shown in B-1. Move. In the course of this movement, in the pulsator 110, the rotation causes the valleys 102 shown in B-2 and the bulges 101 shown in B-3 to occur alternately, so that the clothing on the pulsator undergoes vertical vibration. It repeatedly moves toward the outer circumference. In addition, in this embodiment, since the height difference increases toward the outer circumference, the clothing moves while gradually increasing the vertical movement. Then, as shown in B-4, the clothing that has reached the outer periphery due to the centrifugal force is pushed by the clothing sent one after another and rises on the inner wall surface of the rotating tank 40, and reaches the upper layer of the rotating shaft P, The clothing moves to the lower layer of the opened rotation axis P.

As described above, according to this embodiment, the clothes move to the outer periphery while gradually increasing the vertical vibration, and move to the center again, based on the same principle as in the washing described in the first embodiment. Repeat the cycle leading to. Since the garment is appropriately inverted due to the difference in speed between the inside and the outside, the fabric is not easily entangled, and twisting and wrinkling hardly occur. In addition, the clothing is loosened by the vertical vibration, and warm air can easily enter into the gap, so that the drying time S can be reduced.

(Other embodiments)

As described above, according to this embodiment, by using the pulsators 100 and 110 each having a corrugated surface shape, it is possible to obtain the above-described knock-washing effect and knock-drying effect. However, this effect is not limited to the shapes of the pulsators 100 and 110 according to the first or second embodiment described above. In other words, if the pulsator has a top surface shape in which clothes moving to the outer periphery due to the centrifugal force of the pulsator can move with a gentle waveform trajectory, the pulsator has the same structure as the first and second embodiments. Similar functions and effects can be obtained.

FIG. 7 summarizes other typical development elements of the pulsator. In Fig. 7, the horizontal axis shows the expansion elements, and the vertical axis shows typical application examples. FIG. 64 is a diagram showing a state where the pulsator is attached to a rotary tank. Hereinafter, based on FIGS. 7 and 64, other specific embodiments of the pulsator shown in FIGS. 8 to 63 will be described.

In FIG. 7, A is a development element having the shape of the edge 105, B is a development element having the number of the ridges 101 and the valleys 102, C and D are development elements having a wavy curved surface, The F stage is the top of the waveform This is a deployment element of the rib 106 formed on the base. In addition, as other typical elements, the ventilation part 111 and the deployment element of the reinforcing rib 103 required when the electric drying and washing machine 5 is used will be described later.

[0062] First, in the A-stage, the deployment elements of the edge portion 105 are typically A-1, A-2, and A-3. The three differences of the edge 105 are largely different in the way the valley 102 and the rotary tank 40 are connected. According to A-1, as shown in Fig. 2 (a), the inner wall 45a of the pulsator receiver 45 is exposed in the V-shaped part, and clothing is appropriately The contact can be expected to improve the cleaning effect. On the other hand, as shown in FIG. 64 (a), according to A-2, since the inner wall 45a is concealed by the concave curved surface 123 formed on the outer peripheral end of the valley 102, the concave curved surface Can easily raise the inner wall of the rotary tank 40. Further, according to the above A-3, as shown in FIG. 2 (b), as shown in FIG. 2 (a) and FIG. 64 (a), the V-shaped valley has an intermediate form. Since the concave curved surface having a low height is left at the outer peripheral end of the portion 102, the inner wall 45a is partially exposed, so that both effects can be provided. Hereinafter, these three embodiments will be further described.

First, A-1 is similar to the pulsator 100 according to the first and second embodiments, and does not have an edge portion 105 protruding upward from the upper surface of the waveform. That is, as shown in FIG. 3 and FIG. 5, when viewed from the front, the raised portion 101 and the valley portion 102 form a V-shape. Duplicate explanations are omitted.

(Third embodiment)

Next, in A-2, the edge 105 is formed around the pulsator 120 at the height of the top. The pulsator 120 has a substantially thin plate or a bowl shape with a shallow bottom, and the inner surface of the thin plate is formed into a corrugated shape as in the first and second embodiments. This will be described in a third embodiment shown in FIG.

For example, FIG. 8 shows a pulsator 120 having the configuration of A-2. FIGS. 8A and 8B are external views of a pulsator according to the third embodiment, where FIG. 8A is a perspective view, FIG. 8B is a front view, FIG. 8C is a top view, and FIG. (E) is a cross-sectional view, and (f) is a bottom view. The back view is omitted because it is symmetric with the front view, and the left view is omitted with respect to the right view.

The pulsator 120 according to this embodiment has a shallow bowl-shaped inner surface The inner surface of the bowl is formed by inclined surfaces 121a and 121b from a predetermined position of the edge 105 facing the axis P toward the rotation axis P. When viewed from above, an elliptical inclined surface is formed in the substantially circular outer periphery. The elliptical inclined surface is composed of the two inclined surface forces having a substantially V-shaped cross section. A vertex 122 in the longitudinal direction of the elliptical inclined surface is formed in contact with or close to the edge 105, and both side portions in the longitudinal direction are concave portions that connect the inclined surface and the edge 105. It is formed by a curved surface 123.

[0066] In this embodiment, the edges 105 formed on the outer periphery of the pulsator 120 are formed at the same height, so that the shape can be easily obtained. Further, as shown in FIG. 64 (a), when the pulsator 120 is attached to the rotary tank 40, the edge 105 and the edge 44 of the rotary tank 40 can be flush with each other. The contact between the pulsator 120 and the pulsator 120 can be reduced. In particular, the clothing present in the V-shaped valley portion is pulled up to the edge 44 by the concave curved surface 123 formed on the outer peripheral end of the valley portion 102, and further rises along the inner surface of the rotary tank 40. Therefore, rubbing of clothing can be reduced as compared with the first embodiment.

(Fourth Embodiment)

For example, FIG. 9 shows a pulsator 130 having the shape of A-3. FIGS. 9A and 9B are external views of a pulsator according to the fourth embodiment. FIG. 9A is a perspective view, FIG. 9B is a front view, FIG. 9C is a top view, and FIG. (E) is a cross-sectional view, and (f) is a bottom view. The back view is omitted because it is symmetric with the front view, and the left view is omitted with respect to the right view.

[0068] The pulsator 130 according to this embodiment has an external appearance intermediate between the first embodiment and the third embodiment. That is, also in this embodiment, the two inclined surfaces 121a and 121b are substantially V-shaped, and the ring-shaped edge 105 is formed at an intermediate position of the V-shape. Therefore, both sides (near the top 122) of the V-shaped inclined surfaces 121a and 121b project upward from the edge 105, and both ends of the valley are formed by the edge 105 and the concave curved surface 131. You.

In this embodiment, as shown in FIG. 64 (b), when the pulsator 120 is mounted on the rotary tank 40, the V-shaped sharpest portion is relaxed by the concave curved surface 131. , Pulsay By connecting the inner wall 45a to the inner wall 45a of the receiver 45 and partially exposing the inner wall 45a to the upper part, the clothing is appropriately brought into contact with the exposed portion, so that the cleaning effect can be expected to be improved. Therefore, according to the pulsator 130, the inner wall surface 45a and the clothing are appropriately in contact with each other, so that the cleaning effect can be expected to be improved, and the circulation of the clothing can be improved.

Returning to FIG. 7, next, stages B to F and other development examples will be described. In the following description, characteristic portions (partial designs) of the external view of the embodiment are indicated by solid lines, and portions similar to those of the embodiment are indicated by broken lines. Of course, the whole shape composed of the characteristic part and the broken line is also a novel part, but this is for the purpose of easy description.

Stage B shows the number of expansion elements of the ridge 101 and the valley 102. For example, B-1 has one ridge and valley, B-2 has two ridges and two valleys, and B-3 has one ridge and valley. Indicates that each is composed of three pieces. In addition, a ridge and a valley may be composed of four each. In B-1, about half of the upper surface of the pulsator is a ridge, and the other half is a flat valley. B-2 corresponds to the first to fourth embodiments. In B-3, ridges are arranged at 120 degree intervals, and valleys are provided between them. In this embodiment, the main purpose is to move the clothing so as to slide on the upper surface of the waveform by making the ridges and valleys gently continuous. For this reason, if the number of ridges and valleys is too large, the above-mentioned effect is reduced. In addition, since the pulsator may rotate at a high speed, B-1 which is asymmetric with respect to the rotation axis P has an unsuitable element. Of course, it is effective for washing machines and dry washing machines that assume low-speed rotation. From this point, it can be said that the most effective one is B-2. Of course, it is not to say that using B_3 and four ridges is not effective.

[0072] The C and D stages show the development elements of the curved surface shape of the waveform. C-11 consists of valleys and ridges with flat inclined surfaces. This has been described in the first and fourth embodiments. C-2 is a trough with a large concave surface, C-3 is a trough with a wide flat surface, D-1 is a ridge with a convex surface, and D-2 is C2. And D1, that is, a combination of a valley of a large concave surface and a ridge of a convex surface. D-3 is provided with a projection at a valley, for example, provided with a bearing 104 projecting upward on the rotating shaft P. Further, stages E and F are deployment elements provided with ribs 106 formed on the upper surface of the waveform. As described above, the pulsator of the present embodiment is characterized in that the garment is moved so as to slide on the corrugated upper surface. However, there is also a large factor in removing dirt from clothes due to friction with the pulsator and the rotating tank 40. Therefore, in this embodiment, by providing the slightly overhanging ribs 106 on the upper surface of the pulsator, it is possible to obtain the effect of washing clothes by rubbing while maintaining the tap-washing effect which is a feature of the present pulsator. .

[0074] Forces in which ribs 106 can be provided in various shapes can be considered. Representative examples are shown in steps E and F. Here, the solid line indicates the valley, and the dotted line indicates the center of the raised portion. E-1 has a bar-shaped rib 106 along the valley. E-2 is obtained by adding radial rod-shaped ribs 106b and 106c to the rod-shaped rib 106a of E1. Further, E3 has a bar-shaped rib 106 extending radially at the center of the raised portion.

[0075] On the other hand, the rib 106 is not limited to a rod shape. For example, a rib 106 provided with a plurality of spherical projections on inclined surfaces on both sides of a valley as in F-1; As shown in Fig. 2, a plurality of spherical ribs are provided on both inclined surfaces.

Hereinafter, specific embodiments described with reference to FIG. 7 will be sequentially described. It should be noted that in the slope view, shadow lines are used to represent a three-dimensional image.
