Description

Washing machine {WASHER}

The present invention relates to a washing machine. In particular, the present invention relates to an electric washing machine such as a fully automatic washing machine in which an outer tub and a washing and dehydrating tank are coaxially housed therein.

In the electric washing machine, a proposal has been made that the washing tank or the like is inclined at an angle in order to facilitate taking out the laundry after washing.

For example, Japanese Patent Laid-Open No. 7-265584 discloses that a rear leg installed at a lower part of a washing machine body can be stretched, and when the laundry is taken out, the rear leg is extended to tilt the whole washing machine including the washing tank. The washing machine which can do it and is easy to take out a laundry is disclosed.

Since the conventional washing machine extends the rear leg to tilt the whole washing machine, there is a drawback that the structure for stretching the rear leg is complicated.

In addition, since not only the washing tank but also the housing constituting the outer shape of the washing machine is inclined, the washing machine must be disposed in consideration of the movement of the washing machine (beveled or returned to its original state). For this reason, there existed a fault, such as being difficult to arrange | position a storage shelf etc. adjacent to a washing machine.

On the other hand, if one intends to employ a configuration in which the washing tank is simply inclined, the housing must be enlarged to accommodate the inclined washing tank. In addition, there is a problem that a large-sized washing machine cannot be stored in a waterproof fan set to a predetermined standard dimension.

In addition, the washing tank has an outer tank and an inner tank, and in a fully automatic washing machine having a structure in which the washing tank is suspended in the housing, the configuration of the suspension means must be studied so that the suspended washing tank is always inclined at a desired angle, and the conventional washing tank is always tilted. No configuration has been proposed to forge the suspension, and no suspension means have been devised.

The present invention has been made under such a background, and a main object thereof is to provide a washing machine which is easy to take out laundry from a washing tank with a simple configuration.

The present invention also provides a washing machine in which a washing tank is suspended in a housing, in which the washing tank is always inclined at a desired inclination angle.

In addition, the present invention provides a washing machine in which a washing tank is suspended, in which the washing tank is always inclined at a predetermined angle, and the vibration of the washing and dehydration is less.

In addition, the present invention provides a washing machine having a suspended washing tank, wherein the washing machine is suspended so that the washing tank is tilted at a predetermined angle stably without increasing the appearance.

EMBODIMENT OF THE INVENTION Hereinafter, the washing machine of one Embodiment of this invention is demonstrated in detail, referring an accompanying drawing. 1 is a side cross-sectional view of the washing machine described above.

The washing machine 1 is provided above the washing tank 3 and the washing tank 3 supported by the housing 2 which forms the external shape, the suspension rod 4 in this housing 2, and the washing tank 3, and the washing tank 3 is carried out. It has a water supply mechanism 5 for water supply inside, a drainage mechanism 6 for draining from the inside of the washing tank 3, and the operation part 70 required for operation of this washing machine 1. As shown in FIG. The washing machine 1 is used with its front face 2a in front, and the operation part 70 is arrange | positioned at the front side of the upper surface 2e, and a user operates in front of it.

In the washing machine 1 of this invention, the upper part of the washing tank 3 is arrange | positioned so that it may incline to the front side. In addition, the housing 2 also has a shape in which the upper part of the front side protrudes.

By inclining the washing tank 3 in this way, as shown in the schematic diagram of FIG. 2, the inlet to the washing tank 3 can be arranged in the front side by the dimension L1 compared with the conventional washing machine shown by the broken line, and also the washing tank 3 ) Can be tilted to make the bottom easier to see. In addition, the inner part of the bottom part also moves above the dimension L2. As a result, the laundry can be easily taken out by the user standing at the front.

Hereinafter, it demonstrates in detail. See FIG. 1.

The washing tub 3 includes a bottomed cylindrical outer tub 31 supported by a plurality of suspension rods 4 as suspension means, and an inner tub 32 for washing and dehydration of a cylindrical tubular shape accommodated coaxially in the outer tub 31. ) And the stirring blade 33 provided in the bottom part in the inner tank 32 is provided. The inner tank 32 is rotatably provided in the outer tank 31. The inner tank 32 of this embodiment has many small holes 32a in the peripheral surface. The inner tank 32 and the stirring blade 33 are driven by the drive mechanism 34 including the motor 35 and the like. When washing and rinsing, only the stirring blade 33 rotates in one direction or both directions, and when dewatering, both the stirring blade 33 and the inner tank 32 rotate in one direction at high speed. However, without forming the small hole 32a in the peripheral surface of the inner tank 32, the inner tank 32 stores water at the time of washing, and the water contained in the laundry in the inner tank 32 at the time of dehydration by centrifugal force. It is good also as a structure which is transmitted to the outer tank from the upper side of the inner tank 32, and flows.

That is, the center axis line CL of the outer tub 31 is arrange | positioned so that it may incline with the perpendicular | vertical line VL at predetermined inclination-angle K. As shown in FIG. Here, it is preferable to make the inclination-angle K mentioned above into the range of 5 degrees or more and 20 degrees or less in order to make it easy to take out laundry and to prevent the enlargement of the housing 2. This is because when the inclination angle K is less than 5 degrees, the inclination of the washing tub 3 becomes insufficient, so that the ease of taking out the laundry cannot be sufficiently obtained. In addition, as the inclination angle K increases, the laundry is easier to take out. However, when the inclination angle K exceeds 20 degrees, the inclination of the washing tank 3 becomes too large, so that the amount of the washing tank 3 protruding toward the front side becomes large. This is because the housing 2 is enlarged in size. In particular, when the inclination angle K is set within a range of 8 degrees or more and 12 degrees or less, the laundry is easy to take out, and the cleaning power can be obtained in the same manner as before, and in addition, it is preferable to the front side of the housing 2.

Thus, when the dustproof mechanism 45 of the rear suspension rod 42 is arrange | positioned above the support member 29 of the housing | casing 2, or when arrange | positioning between the support member 29 and the flange part 31u. Can be disposed above the flange portion 31u which is easy to secure a space in the front-rear direction, and the enlargement of the housing 2 can be prevented.

Moreover, since the flange part 31u of the rear part is provided in the position higher than the bottom part of the outer tub 31, for example, in the triangular area partitioned behind the outer tub 31 in the housing 2 as seen from the side. Since the flange part 31u can be arrange | positioned, it is easy to ensure space and it is also preferable to prevent enlargement of the housing | casing 2 from this point.

By the way, when the washing tank 3 is inclined, when washing water or laundry is put, the washing tank 3 tends to displace to the front side. This assumes, for example, that the suspension rod 4 is attached to the lower end of the outer tub 31 both before and after, as shown in Fig. 8A, when a load such as water is applied to the washing tub 3, The center of gravity of the washing tub 3 moves upwardly (see the center of gravity G1 before the movement and the center of gravity G2 after the movement), thereby increasing the weight applied to the front suspension rod 41. Thus, the washing tub 3 tends to be displaced forward, resulting in an enlargement of the housing 2.

In the present embodiment, as shown in Fig. 8B, the rear flange portion 31u is positioned closer to the upper opening 3a along the central axis CL of the outer tub 31 than the front flange portion 31m. As a result, the cross angle D1 formed between the extending direction of the rear suspension rod 42 and the vertical line VL becomes larger as compared with the case of Fig. 8A, and as a result, the gravity applied to the rear suspension rod 42 In W), the force component WR in the direction of rotating the rear suspension rod 42 around the support member 29 becomes large. As a result, since the washing tank 3 can be tensioned more strongly rearward, the tendency of the washing tank 3 to displace forwardward by the load can be suppressed, and the enlargement of the housing 2 can be suppressed. Moreover, since this effect is acquired by providing the flange part 31u in a high position, the enlargement of the housing 2 does not occur, either.

In addition, in this embodiment, as shown in the schematic diagram of FIG. 9, the space | interval L4 of the rear flange part 31u is made narrower than the space | interval L5 of the front flange part 31m (L4 <L5). Thus, when the position of the rear support member 29 of the housing 2 is made the same as the front support member 28, the inclination D2 with respect to the front-rear direction of the rear suspension rod 42 viewed from the plane is the front suspension rod. Since it can make larger than the inclination D3 by 41, the support rigidity with respect to the front-back direction of the rear suspension rod 42 can be made high. This is because the suspension rod is mainly supported by the rigidity of the spring of the vibration isolator for displacement of the washing tub 3 in the extending direction thereof, and also in the contact portion with the flange or the supporting member for displacement in the direction orthogonal to the extending direction. It is supported by the stiffness of, and the latter tends to be higher than the stiffness of the former. For example, when the displacement in the front-back direction is applied to the rear suspension rod 42, the larger the inclination D2 described above, the larger the component in the direction orthogonal to the direction extending in the displacement. As a result of being able to support, vibration in the front-back direction can be suppressed.

In addition, in this embodiment, although the suspension rod 4 consists of two pieces, respectively, the front part and the rear part, it is not limited to this. For example, you may comprise three pieces, one front part and two rear parts, and may consist of three front parts and one rear part.

In addition, although the front suspension rod 41 had the dustproof mechanism 45 in the lower end, it is not limited to this. For example, you may comprise like the rear suspension rod 42 shown in FIG. 5, and may install the dustproof mechanism 45 in the middle part.

In addition, in this invention, in order to incline the washing tank 3, the structure of the suspension rod 4 is changed in the front and rear. Thereby, the arrangement | positioning of the housing 2 support members 28 and 29 can be arrange | positioned in the position which becomes a substantially square square part, for example in plan view, As a result, the support members 28 and 29 are similarly made to the housing | casing conventionally. (2) can be installed.

The housing 2 has a front face 2a, a left face 2b, a right face 2c, a back face 2d and an upper face 2e as shown in FIG. 10, and has a generally rectangular parallelepiped housing shape. have. The housing 2 forms the main member 21 which integrally forms the left side surface 2b, the right side surface 2c, and the back surface 2d, and the front surface 2a as a separate member from this main member 21.

It has a bottom part structural material 24 which forms a bottom surface, supporting the lower end part of this.

The main member 21 is formed by bending a single metal plate, and the left and right side surfaces 2b and 2c extend forward from the left and right end edges of the rear surface 2d of the housing 2, and the left and right side surfaces 2b, From the front end edge of 2c), a pair of front surface parts 21a extend so that they may approach each other. A repair opening 21b for the drainage mechanism 6 or the like is formed between the pair of front surface portions 21a, and an upper end portion of the front surface portion 21a of the main member 21 above the opening 21b. The reinforcement 25 which connects mutually is provided.

The reinforcing material 25 reinforces the peripheral edge part of the opening 21b by caulking a pair of front surface parts 21a of the main member 21, and the main member 21 and also the housing 2 whole of the housing 2 are reinforced. Increasing stiffness and strength. The reinforcing member 25 has a central portion in the left and right directions so as not to collide with the upper portion in the front side of the washing tub 3, and the upper portion 25a in the vertical direction expands in the front side than the upper portion 25b. It is formed in substantially L-shaped cross-sectional shape. The reinforcing effect of the cross-sectional shape which the part expanded to the front side in this way is high, and a reinforcement effect is preferable.

In addition, the support members 28 and 29 mentioned above are caulked at the four corners of the upper end part of the main member 21. As shown in FIG. The supporting members 28 and 29 also function as reinforcing members for reinforcing four corners of the main member 21 in addition to the members for attaching the suspension rod 4. The supporting member 28 in the front is corked with the front surface portion 21a of the reinforcement 25 and the main member 21, and also serves as a reinforcement member of the connecting portion of the reinforcement 25 and the main member 21, have.

The front plate 22 is a member covering the front of the main member 21, and integrally forms the front end portion of the front face 2a and the left and right side surfaces 2b and 2c of the housing 2. Formation of the front plate 22 can use well-known methods, such as a resin molding process and a metal plate press process. The front plate 22 is an exterior member of the washing machine 1 and is used as a cover of the opening 21b for repair described above, and is detachably attached to the main member 21. That is, a plurality of hook portions 22f (only a part of which is shown) extending downward are provided on the rear surface of the front plate 22, and the front end portion 21a of the front member 21 of the main member 21 is provided with a tip portion of the hook portion 22f. The front plate 22 is attached to the main member 21 by engaging with the locking hole 21f.

The lower portion 22a of the front plate 22 is formed to extend substantially vertically in the vertical direction. In addition, the front plate 22 has a shape expanded from the middle part in the vertical direction toward the front side, and the upper portion 22b is inclined so that the projection toward the front side becomes larger as the position is higher in the vertical direction.

The bottom structural member 24 has an upper part 24a connected to the lower end of the front plate 22 and the main member 21, a lower part 24b formed concave in the front-rear direction than the upper part 24a, and a lower part 24b. It has a leg 24c attached to four corners of.

The upper plate 23 has an inlet 23a for putting the laundry in and out of the washing tank 3 at its center. The inlet 23a is formed to face the upper opening 3a of the washing tub 3, and the center position of the inlet 23a at the time of measuring in the front-back direction is located ahead of the center position of the upper surface plate 23. As shown in FIG. The peripheral edge part of the inlet port 23a is formed in the surface of the lower gradient toward the front side, and the cover 26 which covers the inlet port 23a so that opening and closing is possible is attached.

The front end portion of the top plate 23 has a protrusion 23b protruding toward the front side in accordance with the expansion of the upper portion 22b of the front plate 22. The operation part 70 is provided in this protrusion part 23b.

The operation part 70 has the operation surface 72 in which operation switches etc. are arranged, and the circuit board 71 (refer FIG. 1) which comprises the circuit containing an operation switch etc. The circuit board 71 is arrange | positioned below the operation surface 72 in the watertight state, and has the control circuit which drives each part of the washing machine 1 according to the setting of an operation switch. The operation surface 72 becomes a surface of a downward gradient toward the front side, and the peripheral surface of the operation surface 72 and the inlet port 23a forms the upper surface 2e which consists of continuous inclined surfaces.

In addition, the top plate 23 accommodates the water supply mechanism 5 behind the inlet 23a, as shown in FIG.

The water supply mechanism 5 has a water supply pipe 51 whose one end is led out of the housing 2 and connected to a water supply facility (not shown) such as an external washing water supply system, and a water supply valve for opening and closing the flow of the water supply pipe 51 ( 52 and a water spout forming member 53 for forming the water spout 5a facing the inside of the washing tank 3 at the other end of the water supply pipe 51.

As shown in Fig. 11, the water pouring tool forming member 53 includes a container 53a for introducing detergent contained therein into the washing tank 3 together with water from the connection port 51a of the water supply pipe 51; The water flow guide member 53b is formed integrally with the water from the water pouring port 5a to guide the water to the predetermined direction. The water injection hole 5a is partitioned behind the water flow formation member 53b. The water inlet 5a is provided near the highest position of the upper end part of the washing tank 3 as the peripheral edge part of the upper side of the washing tank 3 and the upper opening 3a of the washing tank 3. The water flow guide member 53b guides the water from the water inlet 5a to the laundry attached to the inner circumferential surface of the inner tank 32 of the washing tank 3.

In this way, since the water inlet 5a flows water backward into the washing tank 3 at the rear side of the peripheral edge portion of the upper opening 3a of the washing tank 3, the water is rearward in the washing tank 3. As a result of being poured into the laundry on the side and collecting in the bottom of the washing tank 3 and seeping into the laundry on the front side of the washing tank 3, the laundry in the washing tank 3 can be thoroughly wetted.

In addition, since the water from the spout 5a is immersed in the laundry stuck in the washing tub 3, the laundry can be easily unwound after the intermediate dehydration performed during washing.

And the upper part of the outer tank 31 is formed so that the water-harvesting chamber 31a (FIG) may protrude to the outer side of radial direction as shown in FIG. The water-sealing chamber 31a is for preventing the water level in the outer tank 31 from exceeding a predetermined height, and the water-sealing chamber 31a and the inside of the outer tank 31 communicate with each other through the water-hole 31b. The water-wetting chamber 31a is arrange | positioned in the vicinity of the corner part in the housing | casing 2 used as the back side of the washing tank 3. Since the water-washing chamber 31a arrange | positioned at the back side of the washing tank 3 can be arrange | positioned at the high position of the inclined washing tank 3, it is easy to ensure the water level in the washing tank 3. The water supply chamber 31a is connected to the drain pipe 61 through the water supply pipe 63.

As shown in Fig. 1, the drain mechanism 6 includes a drain pipe 61 having one end connected to a drain port 31c at the bottom of the outer tub 31, and a drain valve for opening and closing the flow of the drain pipe 61 ( 62). The drain port 31c is arrange | positioned at the front end part of the bottom part of the outer tub 31, and is formed in the lowest part of the outer tub 31 of the inclined washing tank 3. As shown in FIG. The water supply pipe 63 is connected to the water discharge pipe 61 at a portion of the water discharge pipe 62 downstream from the water discharge valve 62, and the other end (not shown) of the water discharge pipe 61 is led out of the washing machine.

Moreover, as shown in FIG. 13, the drain valve 62 is arrange | positioned in the vicinity of the drain port 31c at the bottom part of the washing tank 3, and the motor 35 is arrange | positioned at the back side of the bottom part. Usually, although the motor 35 is a member which protrudes, in the inclined washing tank 3, the rear side part of the bottom part is easy to ensure space in an up-down direction compared with a front side part, and can be arrange | positioned without difficulty.

Moreover, the balancer mechanism 8 which suppresses a vibration is provided in the bottom part of the outer tub 31. As shown in FIG.

The balancing device mechanism 8 is comprised from the container which partitions a storage chamber, and the predetermined liquid enclosed in the storage chamber, and the two container which liquid entered. The two containers are provided on opposite sides with the center at the bottom of the outer tub 31.

The liquid is, for example, brine and is encased to 60 to 90% of the volume of the vessel so that it can move in the vessel. Here, the use of brine is to increase the specific gravity than that of the big thing to increase the dust-proofing effect, and also to prevent freezing at low temperatures. Moreover, if it is brine, it is harmless even if it leaks.

Each of the two containers is substantially fan-shaped in plan view, elongated in the inclined direction with respect to the front-rear direction, and liquid flows easily along this longitudinal direction. Since the longitudinal direction of a container is an inclination direction with respect to the front-back direction, liquid flows easily in both the front-back direction and the left-right direction.

The balancer mechanism 8 functions as a vibration damper when the inner tank 32 or the like reaches a high speed rotation at the time of dehydration start or the like. That is, when the washing tank 3 vibrates in the horizontal direction, the brine moves in the container, and the vibration of the washing tank 3 is suppressed by the reaction force or the viscous resistance. In addition, since the container is fan-shaped, liquid flows so as to conform to the fan shape, and vibration in the rotational direction of the outer tub 31 is also suppressed. Moreover, since a pair of containers are arranged symmetrically, the vibration suppressing effect is high. Here, the shape of a container is not limited to the above-mentioned thing, Since the vibration of the front-back direction is assumed in the inclined washing tank 3, what is necessary is just a shape extended at least in the front-back direction.

Moreover, since the balancer mechanism 8 is comprised by the container, what is necessary is just a shape in which a liquid flows, and the freedom degree is high, and as a result, it can arrange | position in the empty space of the bottom part of the washing tub 3. In addition, since the balancer mechanism 8 is at the bottom, it is not necessary to enlarge the planar shape of the housing 2.

In this washing machine 1, the washing tank 3 is in an inclined state at the time of operation and stop of washing, rinsing and dehydration.

At the time of washing | cleaning, water is first poured into the washing tank 3 by the water supply mechanism 5a by the water supply mechanism 5, and the stirring blade 33 is rotated after that, and laundry is stirred. At this time, since the washing tank 3 is inclined, it is sufficiently stirred.

In addition, in the inclined washing tank 3, it is assumed that the washing tank 3 vibrates at the time of dehydration starting by shifting the laundry to the front side which becomes downward. In particular, when the washing tub 3 is strongly pulled backward by the suspension rod 4, the tendency becomes stronger. In this embodiment, the vibration at the time of dehydration can fully be suppressed by the rear suspension rod 42 and the balancer mechanism 8 which narrowed the space | interval.

Thus, according to this embodiment, since the washing tank 3 is arrange | positioned inclined to the front side as shown in FIG. 2, a user standing at the front side is easy to take out laundry from the upper opening 3a of the washing tank 3; . In addition, since the washing tank 3 is inclined to the front side, the eyes reach the front of the bottom of the washing tank 3 in particular, and as a result, it is easy to take out the laundry and can easily check whether there is no laundry left. Therefore, it can be set as the washing machine 1 which is easy to use.

In addition, as shown in Fig. 1, only the upper portion of the front surface 2a of the housing 2 is swollen, so that the lower portion of the front surface 2a of the housing 2 is relatively concave, and the user can see from the front side. When approaching the washing machine 1, the lower part of the front surface 2a is not obstructed. For this reason, since the upper body of the user can come closer to the washing machine 1, the distance to the bottom of the inclined washing tank 3 is not far, and thus it is easier to take out the laundry. In particular, since the lower part 24b, the leg part 24c, etc. of the bottom structural material 24 are located behind the operation part 70, the leg part 24c etc. are not obstructed when a user moves closer from the front side. Not desirable.

And since only the upper part of the front surface 2a of the housing 2 expands to the front side according to the inclination of the washing tank 3, the lower part of the housing 2 can be made into the dimension which does not change with the housing of the conventional washing machine. As a result, the washing machine 1 of the present invention can be put in a waterproof fan made to a standard dimension for a conventional washing machine.

In addition, since the washing tank 3 is always arranged in an inclined state, a configuration for switching the inclined state is unnecessary, the structure of the washing machine 1 can be simplified, and failures are unlikely to occur.

As shown in Fig. 10, the housing 2 includes a front plate 22 which forms the front face 2a of the expanded shape, and a main member 21 which forms the left and right side surfaces 2b, 2c and the like. By setting it as a separate member, the main member 21 can be made into a simple structure like the conventional one, and can be formed at low cost. In addition, since only the front plate 22 needs to be handled in order to expand the front surface 2a, the processing for inflation is easy. As a result, an increase in the processing cost of the housing 2 can be prevented. Here, even if a part of side surface is formed in the front plate 22, the same effect can be acquired.

Moreover, since the operation part 70 is provided in the protrusion part 23b of the upper surface plate 23, it is easy for a user to operate the operation part 70 from the front side, and also the content of the operation part 70 is easy to see.

And since the operation surface 72 of the operation part 70 is a downward gradient toward a front side, it is easy to operate further and can be made easy to see, and can improve operability.

In addition, since the main member 21 can be formed by bending a single metal plate as in the prior art, it can be easily and inexpensively processed.

And since the reinforcing material 25 can reinforce the peripheral edge part of the opening 21b, the intensity | strength of the main member 21 and also the housing 2 can be raised, and shake and vibration can also be suppressed. In particular, the reinforcing material 25 expanded to the front side is preferable because of its high rigidity.

Moreover, since the reinforcement material 25 expanded to the front side does not interfere with the washing tank 3, even if shaking and vibration generate | occur | produce, there is little possibility that the washing tank 3 and the reinforcing material 25 may be damaged. Here, no interference means not touching or bumping in a normal state, and may be allowed to touch or hit temporarily in the case of large vibration.

And the washing tank 3 contains the outer tank 31 and the inner tank 32 for washing and dehydration, and when the washing tank 3 is applied as a fully automatic washing machine 1, the favorable washing tank 3 can be made into the inclined washing machine 1. have. In this way, if the fully automatic washing machine is used, taking out the laundry only after the completion of washing is more preferable.

In addition, when the inclination angle K of the washing tank 3 is in the range of 5 to 20 degrees, taking out the laundry from the washing tank 3 is easy, and the housing 2 is enlarged with the tilting of the washing tank 3. You do not have to do.

Thus, according to the washing machine 1 of this embodiment, it can be set as the washing machine 1 which is easy to take out laundry. In addition, the appearance of the washing machine 1 is not large, so that the washing machine 1 can be disposed in a waterproof fan of a conventional standard dimension. Moreover, since the washing tank 3 is always arrange | positioned in inclined state, it can be set as the washing machine 1 which is simple in structure and hard to break.

Moreover, in the above-mentioned embodiment, although the washing machine 1 was a one-piece type which supported the washing tank 3 of the double structure to the housing 2, it is not limited to this. For example, the washing machine is a double tank having a washing tank and a dehydrating tank, and the washing tank may be fixed to the housing by a single tank having a stirring blade at the bottom, and the present invention may be applied to the washing tank.

In addition, it is possible to perform various design changes in the range which does not change the summary of this invention.

According to the washing machine of this invention, it can be set as the washing machine which is easy to take out laundry. Moreover, the appearance of the washing machine is not large and it is possible to arrange the washing machine in a waterproof fan of conventional standard dimensions. In addition, since the washing tank is always disposed in an inclined state, it is possible to make a washing machine having a simple structure and difficult to break down, and water from the water inlet is poured into the laundry in front of the washing tank, As a result of permeating the laundry in front of the laundry, there is an effect that can thoroughly wet the laundry in the washing tank.
