Disclosure of Invention
Technical problem to be solved by the invention
However, when the rotary drum (washing tub) rotates during the spin-drying operation, the laundry sticks to the inner circumferential surface of the drum and rotates together with the rotary drum. When the rotary drum rotates and laundry is offset and stuck to the inside of the rotary drum, the laundry becomes an eccentric load and swings in the rotation direction side of the rotary drum. In the upper rotating area of the rotating drum, the laundry in the rotating drum is rotated upward together with the rotating drum. As a result, the rotary drum swings upward in the upper rotary area of the rotary drum.
In contrast, in the lower rotation region of the rotary drum, the laundry in the rotary drum is rotated downward together with the rotary drum. Therefore, in the lower rotation region of the rotary drum, the rotary drum swings to the lower side, and thus the water tank receives a downward pressure via the rotary drum. As a result, one of the portions of the water tank covering the lower rotation region sinks down more greatly than the portion covering the upper rotation region.
In the washing machine described in patent document 1, the coil spring is located at the center of the lower portion of the water tub. Therefore, during the dewatering operation, one of the portions covering the lower spinning region may sink more greatly than the portion covering the upper spinning region in the water tub. As a result, the posture of the water tank may become unbalanced during the dehydration operation.
The invention aims to provide a washing machine capable of stably supporting a water tank during dehydration operation.
Means for solving the problems
According to a first aspect of the present invention, a washing machine includes a washing tub, a housing, and an elastic member. The washing machine is rotatably supported around a rotating shaft. The water tank accommodates the washing tank. The housing accommodates the water tank. The elastic member is attached to the housing and to a lower portion of the water tank. The position of the elastic member is different from the position of the rotation shaft in the position in the width direction of the housing.
Effects of the invention
According to the present invention, the water tank can be stably supported during the dehydration operation.

Laundry can be put into drum 115 through drum opening 15 a.
The drum 115 also includes a rotating shaft 15 d. The rotation shaft 15d is a shaft passing through the center of the drum opening 15a and the center of the drum bottom 15 c. In the present embodiment, the rotation axis 15d is inclined at an acute angle θ with respect to the front-rear direction. The rotation shaft 15d may be parallel to the front-rear direction.
The water tank 116 has a hollow shape. The water tank 116 accommodates the drum 115. The water tank 116 is disposed inside the housing 114.
The water tank 116 has a tank opening 16a, a tank side 16b, and a tank bottom 16 c. The water tank side portion 16b has a substantially cylindrical shape with both front and rear ends open. The drum side portion 15b is disposed inside the water tank side portion 16 b. The tank bottom 16c is provided at the rear of the tank side 16b and closes the rear of the tank side 16 b. The tub bottom 16c faces the drum bottom 15c from the rear. The water tank opening 16a is provided in the front of the water tank side 16 b. The water tank opening 16a communicates the inside of the water tank 116 and the outside of the water tank 116. The water tank opening 16a faces the drum opening 15a from the front. The water tank opening 16a faces the door 112 in the closed state.
The inside of the water tank 116 represents a space surrounded by the tank side portion 16b and the tank bottom portion 16 c. A drum 115 is disposed inside the water tank 116.
When door 112 is opened, drum opening 15a and water tank opening 16a face the outside of casing 114. As a result, the user can insert laundry into drum 115 through drum opening 15a and water tank opening 16 a.
The damper 117 is interposed between the lower portion 16d of the water tank 116 and the bottom 14b of the housing 114. The damper 117 reduces vibration of the water tub 116. The damper 117 supports the lower portion 16d of the water tub 116. In addition, the damper 117 supports the rear portion of the water tub 116. The dampers 117 are provided in a pair. The pair of dampers 117 are disposed at a distance from each other in the left-right direction. The pair of dampers 117 support both right and left side portions of the water tub 116.
The washing machine 100 further includes a drum motor 118, an output shaft 119, a plurality of hole parts 120, and a plurality of baffles 121.
The drum motor 118 rotates the drum 115. The drum motor 118 is connected to the drum 115 via an output shaft 119. The output shaft 119 rotatably supports the drum 115. A plurality of holes 120 are formed in the drum 115. The plurality of holes 120 penetrate the drum 115. Each of the plurality of baffles 121 is formed on the inner circumferential surface of the drum 115. Each of the plurality of baffles 121 protrudes toward the inside of the drum 115. The plurality of baffles 121 are arranged along the circumferential direction of the drum 115.
The sequence of the washing operation performed by the washing machine 100 will be described.
First, laundry is put into drum 115. Then, water is supplied into drum 115 through the plurality of holes 120, and the laundry is soaked in the water. Then, the drum 115 is rotated by the power of the drum motor 118. When the drum 115 rotates, the laundry is lifted up by the damper 121. Then, the laundry falls by gravity and hits the inner circumferential surface of the drum 115. Then, as drum 115 continues to rotate, the operation of lifting the laundry and the operation of striking the laundry against the inner circumferential surface of drum 115 are repeated alternately. As a result, the laundry is washed.
The washing machine 100 further includes a fan 122, a heater 123, and a duct 124. The fan 122 is connected to the drum 115 via a heater 123 and a duct 124. During the drying operation, warm air generated by the fan 122 and the heater 123 is supplied to the inside of the water tank 116 through the duct 124. The warm air supplied to the inside of water tub 116 is supplied to the inside of drum 115 through holes 120. As a result, the laundry inside the drum 115 is dried.
The washing machine 100 washes laundry by performing, for example, a washing operation, a rinsing operation, a dehydrating operation, and a drying operation. The washing operation means washing of laundry. The washing operation means washing of the laundry. The dehydration operation means dehydrating the laundry. The drying operation means drying the laundry. In addition, the washing machine 100 may not have a drying function.
Next, the rotation of the drum 115 will be described with reference to fig. 3. Fig. 3 is a front view of the washing machine 100. In fig. 3, the door 112 and the front portion 14a (see fig. 2) of the housing 114 are omitted.
In fig. 3, rotation direction a indicates a direction in which drum 115 rotates about rotation shaft 15d when washing machine 100 performs a spin-drying operation. In the present embodiment, the rotation direction a represents a clockwise direction on the paper of fig. 3.
The drum 115 includes an upper rotation region α, and a lower rotation region β.
The upper rotation region α indicates a region of the drum 115 in which the rotation direction a of the drum 115 is directed upward. In the present embodiment, as shown in fig. 3, the upper rotation region α represents a region on the right side of the rotation shaft 15d in the drum 115.
The lower rotation region β indicates a region of the drum 115 in which the rotation direction a of the drum 115 is directed downward. In the present embodiment, as shown in fig. 3, the lower rotation region β represents a region on the left side of the rotation shaft 15d in the drum 115.
In the dewatering operation, the drum 115 rotates in a fixed direction around the rotation shaft 15 d. In addition, in general, the drum 115 rotates at a higher speed in the dehydration operation than in the washing operation. In the present embodiment, the drum 115 rotates in the rotation direction a (see fig. 3) during the spin-drying operation. In this case, the drum 115 rotates so that the portion of the drum 115 to which the laundry adheres swings in the rotation direction a. Therefore, during the dewatering operation, since the drum 115 swings downward in the lower rotation region β, the portion of the water tank 116 covering the lower rotation region β receives a downward pressure via the drum 115. In contrast, the drum 115 swings upward in the upper rotation region α. As a result, the water tank 116 is likely to be displaced and sink during the dehydration operation.
Next, the washing machine 100 will be further described with reference to fig. 2 to 4.
As shown in fig. 2 and 3, the washing machine 100 further includes a first elastic member 131, a second elastic member 132, a first spacing member 133, and a third spacing member 135.
The first elastic member 131 is an elastically deformable member. The first elastic member 131 is, for example, a coil spring.
The first elastic member 131 is attached to the housing 114 and to the upper portion of the water tank 116.
The first elastic member 131 has an upper end 31a and a lower end 31 b.
The upper end 31a represents a portion of the first elastic member 131 attached to the housing 114. The lower end 31b represents a portion of the first elastic member 131 attached to the water tank 116. The first elastic member 131 has a shape extending from the upper end portion 31a toward the lower end portion 31 b.
The upper end portion 31a is located above the lower end portion 31 b.
The first elastic member 131 is elastically deformed in a direction in which the upper end portion 31a and the lower end portion 31b approach and separate from each other.
The first elastic member 131 is attached to the housing 114, and includes not only a case where the first elastic member 131 is directly attached to the housing 114 but also a case where the first elastic member is indirectly attached via a member such as a bracket. The first elastic member 131 is attached to the upper portion of the water tub 116, and includes not only a case where the first elastic member 131 is directly attached to the upper portion of the water tub 116 but also a case where the first elastic member is indirectly attached via a member such as a bracket.
The first elastic member 131 is located above the rotation shaft 15 d. In the position in the left-right direction, the position of the first elastic member 131 is the same as the position of the rotation shaft 15 d.
In the direction in which the first elastic member 131 contracts, the restoring force of the first elastic member 131 is generated. At this time, the restoring force of the first elastic member 131 is generated in the direction Y1 in which the lower end 31b approaches the upper end 31 a.
When the restoring force of the first elastic member 131 is generated, the restoring force of the first elastic member 131 acts on the water tank 116 so that the upper portion of the water tank 116 is lifted. As a result, the first elastic member 131 supports the upper portion of the water tub 116.
Fig. 4 is an enlarged view of the second elastic member 132. Referring to fig. 2 to 3, the mounting structure of the second elastic member 132 will be described.
As shown in fig. 2 to 4, the second elastic member 132 is attached to the housing 114 and to the lower portion 16d of the water tank 116.
The second elastic member 132 is attached to the housing 114, and includes not only a case where the second elastic member 132 is directly attached to the housing 114 but also a case where the second elastic member 132 is indirectly attached via a member such as a bracket. The second elastic member 132 is attached to the lower portion 16d of the water tub 116, and includes not only a case where the second elastic member 132 is directly attached to the lower portion 16d of the water tub 116 but also a case where it is indirectly attached via a member such as a bracket.
In the present embodiment, the second elastic member 132 is indirectly attached to the housing 114 via the first spacer member 133. The second elastic member 132 is indirectly attached to the lower portion 16d of the water tub 116 via the third spacer 135.
The first spacer member 133 is fixed to the housing 114. The first spacing members 133 are formed of, for example, sheet metal or resin. The first spacer 133 is disposed between the water tank 116 and the front portion 14a of the housing 114. In the present embodiment, the first partition member 133 supports the front portion of the water tub 116 via the second elastic member 132.
The second elastic member 132 will be described in detail. The second elastic member 132 is an example of the elastic member of the present invention.
The second elastic member 132 is an elastically deformable member. The second elastic member 132 is, for example, a coil spring.
The second elastic member 132 has a first end 32a and a second end 32 b. The second elastic member 132 has a shape extending from the first end portion 32a toward the second end portion 32 b.
The first end portion 32a represents a portion of the second resilient member 132 that is mounted directly or indirectly to the housing 114.
In the present embodiment, the first end portion 32a is formed in a hook shape. The first end portion 32a is attached to the first spacer member 133. As a result, the first end portion 32a is indirectly attached to the housing 114 via the first spacer member 133.
In the present embodiment, the second end portion 32b is formed in a hook shape. The second end 32b is attached to the third spacer 135. As a result, second end 32b is indirectly attached to lower portion 16d of water tub 116 via third spacer 135.
The first end portion 32a is located above the second end portion 32 b.
The second elastic member 132 is elastically deformed in a direction in which the first end portion 32a and the second end portion 32b approach and separate from each other.
The second elastic member 132 is located below the rotation shaft 15 d. The position of the second elastic member 132 is different from the position of the rotation shaft 15d in the left-right direction. When the washing machine 100 is viewed from the front, the second elastic member 132 is located below the lower rotation region β (see fig. 3).
The second elastic member 132 is located leftward with respect to the rotation shaft 15 d. The first end 32a is located leftward with respect to the rotation axis 15d, and the second end 32b is located leftward with respect to the rotation axis 15 d.
The first end portion 32a is located leftward relative to the second end portion 32 b.
The left-right direction is an example of the width direction of the present invention. The left-right direction is a direction parallel to the horizontal direction. The left-right direction is a direction perpendicular to the rotation axis 15 d. The left side is an example of one side in the width direction of the present invention.
The second elastic member 132 generates a restoring force of the second elastic member 132 in a direction in which contraction proceeds. At this time, as shown in fig. 2, the restoring force of the second elastic member 132 is generated in the direction Y2 in which the second end 32b approaches the first end 32 a.
When the restoring force of the second elastic member 132 is generated, the restoring force of the second elastic member 132 acts on the water tank 116 so that the lower portion 16d of the water tank 116 is lifted. As a result, the second elastic member 132 supports the lower portion 16d of the water tank 116.
As described above with reference to fig. 2 to 4, in the present embodiment, the drum 115 rotates in the rotation direction a during the spin-drying operation. Therefore, during the dehydration operation, the lower rotation region β swings downward. As a result, the left portion of the water tank 116 sinks more greatly than the right portion of the water tank 116 during the dehydration operation. The right portion of the water tank 116 indicates a portion of the water tank 116 covering the upper rotation region α. The left part of the water tank 116 represents a part of the water tank 116 covering the lower rotation region β.
However, as shown in fig. 3, the position of the second elastic member 132 is different from the position of the rotation shaft 15d in the left-right direction. In the present embodiment, the rotary shafts 15d are disposed in the right and left center portions of the water tank 116. The second elastic member 132 is disposed at a lower left portion of the water tank 116. The second elastic member 132 is mounted to a lower left portion of the water tub 116. Therefore, the left portion of the water tank 116 can be supported from below by the second elastic member 132. As a result, since the left portion of the water tank 116 can be prevented from sinking more than the right portion of the water tank 116 during the dehydration operation, the problem of the water tank 116 sinking due to offset can be prevented, and the water tank 116 can be stably supported.
Further, if the second elastic member 132 is disposed at the lower left portion of the water tank 116, the restoring force of the second elastic member 132 acts on the left portion of the water tank 116 when the rotation of the drum 115 is stopped. As a result, when the rotation of drum 115 is stopped, the right portion of water tank 116 sinks downward than the left portion, and therefore the position of water tank 116 may shift to the right side.
However, as shown in fig. 3, the first end portion 32a is located leftward relative to the second end portion 32 b. Therefore, when the rotation of drum 115 is stopped, the restoring force of second elastic member 132 can be generated toward the left side with respect to water tub 116. As a result, when the rotation of drum 115 is stopped, the position of water tub 116 can be prevented from moving to the right, and therefore water tub 116 can be stably supported.
In the case where drum 115 rotates in the direction opposite to the rotation direction a shown in fig. 3 during the dewatering operation, α and β are opposite to each other in the left-right direction and the right side swings toward the lower side. In this case, the sink of the right portion of water tank 116 becomes larger than the sink of the left portion of water tank 116. Therefore, in this case, the second elastic member 132 is disposed at the lower right portion of the water tank 116.
The embodiments of the present invention are explained above with reference to the drawings (fig. 1 to 4). However, the present invention is not limited to the above-described embodiments, and can be carried out in various aspects (for example, (1) to (3)) within a range not departing from the gist thereof. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some of the components may be deleted from the entire components shown in the embodiments. The drawings are schematically illustrated in the main for convenience of understanding, and the number of the illustrated components may be different from the actual one due to convenience of drawing. The components of the above-described embodiment are examples, and are not particularly limited, and various modifications may be made without departing from the scope of the present invention.
(1) A first modification of the washing machine 100 will be described with reference to fig. 5. Fig. 5 is a sectional view showing a first modification of the washing machine 100.
As shown in fig. 5, in the second elastic member 132, the second end portion 32b may be located above the first end portion 32 a. In this case, the first end portion 32a is positioned rightward relative to the second end portion 32 b. The right side is an example of the other side in the width direction of the present invention.
In this case, the restoring force of the second elastic member 132 is generated in the direction in which the second elastic member 132 extends. At this time, the restoring force of the second elastic member 132 is generated in the direction Y3 in which the second end 32b is separated from the first end 32 a. As a result, the second elastic member 132 can support the lower left portion of the water tank 116 in the same manner as the second elastic member 132 (see fig. 3) of the present embodiment.
(2) Referring to fig. 6, a second modification of the washing machine 100 will be described. Fig. 6 is a front view showing a second modification of the washing machine 100.
As shown in fig. 6, the washing machine 100 may further include a third elastic member 136. The third elastic member 136 is an elastically deformable member. The third elastic member 136 is, for example, a coil spring.
The third elastic member 136 includes a third end 36a and a fourth end 36 b. The third end portion 36a represents a portion of the third end portion 36a that is directly or indirectly attached to the housing 114. The fourth end 36b is a portion of the third end 36a that is directly or indirectly attached to the lower portion 16d of the water tub 116.
In the position in the left-right direction, the position of the third elastic member 136 is the same as the position of the rotation shaft 15 d. In the left-right direction, the position of the third end 36a and the position of the fourth end 36b are the same as the position of the rotation shaft 15 d.
The third end portion 36a is located above the fourth end portion 36 b. The third elastic member 136 generates a restoring force of the third elastic member 136 in a direction in which contraction progresses. Therefore, the left portion of the lower portion 16d of the water tub 116 can be supported by the second elastic member 132, and the left and right central portions can be supported by the third elastic member 136. As a result, the lower portion 16d of the water tank 116 can be effectively supported by the second elastic member 132 and the third elastic member 136.
In addition, the third elastic member 136 shown in fig. 6 may be provided in contrast to the first modification of the washing machine 100 shown in fig. 5. In this case, the fourth end 36b is located above the third end 36a (see fig. 5). Then, a restoring force of the third elastic member 136 is generated in a direction in which the third elastic member 136 contracts. As a result, the lower portion 16d of the water tub 116 can be effectively supported by the second elastic member 132 and the third elastic member 136.
(3) In the washing machine 100 (see fig. 3), the first modification of the washing machine 100 (see fig. 5), and the second modification of the washing machine 100 (see fig. 6) according to the present embodiment, the first end 32a is located leftward relative to the second end 32 b. However, the present invention is not limited thereto. In the left-right direction position, the position of the first end 32a may be the same as the position of the second end 32 b. Therefore, as in the case of the washing machine 100 of the present embodiment, it is possible to suppress the left portion of the water tank 116 from sinking more than the right portion of the water tank 116 during the dehydration operation. As a result, the water tank 116 can be stably supported.
