Description

  The present invention belongs to the field of washing machines, and specifically to washing machines.

  Washing machines are designed as devices for washing clothes using electricity. Generally, a washing machine rotates a tub for storing washing water, a rotatable tub rotatably mounted inside the tub, a pulsator rotatably mounted at the bottom of the rotatable tub, and a rotary tub and a pulsator. And a clutch configured as described above. When the rotating tub and the pulsator rotate while the clothes and the detergent are put in the rotating tub, the pulsator and the pulsator shake the washing water together with the clothes put in the rotating tub, thereby removing dirt from the clothes.

  To increase the washing capacity of the washing machine, a larger rotating tub is required. That is, it is necessary to increase the height or diameter of the rotating tank. In addition, when the rotary tub has a larger size, the tub for housing the rotary tub and the housing for storing the tub also need to be increased with the expansion of the rotary tub.

  However, the increase of the housing corresponding to the appearance of the washing machine is limited to the space of the installation area of the washing machine. In a general user's house, since the installation position of the washing machine is limited, it is not very realistic to achieve the purpose of increasing the capacity of the washing tub by increasing the housing of the washing machine. Therefore, how to increase the capacity of the rotary tub without increasing the housing of the washing machine has become a major challenge for designers.

  Usually, a suspension type vibration damping member for reducing the vibration of the rotary tank is provided between the rotary tank and the housing. However, since the suspension type vibration damping member is generally of a cable-stayed type, it tends to occupy a large space between the rotary tub and the housing, which seriously limits the volume of the rotary tub.

  In view of the above, the present invention is proposed.

  The technical problem to be solved by the present invention is to solve the deficiencies in the prior art, provide a mounting member, and assemble the lower end of the suspension type vibration damping member to the mounting member, so that the mounting space of the suspension It is to provide a washing machine that reduces the size. As a result, the mounting space of the suspension type vibration damping member can be reduced without increasing the housing of the washing machine, so that the accommodation space held in the washing tub increases, and the capacity of the washing tub can be increased.

In addition to the above, it further includes a dam structure for blocking water discharged from the inner tank 200 from overflowing. The whole dam structure is located below the bottom of the inner tank 200. The inner tank 200 has a water injection function.

  By providing the blocking structure, when the water is discharged from the inner tank 200, the water is blocked by the blocking structure, so that a situation in which the water overflows is prevented. Further, the entire dam structure is located below the inner tank 200, and does not have a partial structure located between the side wall of the inner tank 200 and the housing 100. Therefore, a sufficient space for the capacity expansion of the inner tank 200 is provided without limiting the capacity expansion of the inner tank 200.

Further, the upper end of the side wall of the water collecting chamber 400 is lower than the bottom of the inner tub 200, and the entire water collecting chamber 400 is located below the bottom of the washing tub 206. The side wall does not have a structure located between the inner tank 200 and the housing 100. Therefore, it is not necessary to provide a certain safety distance between the inner tank 200 and the dam structure, and it is possible to prevent the inner tank 200 from colliding with the dam structure and being damaged. Further, since there is no need to provide a safety distance between the dam structure and the housing 100, it is only necessary to design a safety distance between the inner tank 200 and the housing 100. Therefore, the diameter of the inner tank 200 can be greatly increased, and the capacity of the inner tank 200 can be more effectively increased.

  A certain interval is provided between the side wall of the water collecting chamber 400 and the outer wall at the bottom of the inner tank 200.

  By making the upper end of the side wall of the water collecting chamber 400 lower than the bottom of the inner tub 200 and providing a fixed interval between the side wall of the water collecting chamber 400 and the outer wall of the bottom of the inner tub 200, the washing tub is provided.

  As shown in FIGS. 1 to 3, the present embodiment further restricts the first embodiment. In this embodiment, the blocking structure includes a mounting plate 500 and a blocking rib 501 provided on the mounting plate 500, and forms a water collecting chamber 400 so as to be surrounded by the mounting plate 500 and the blocking rib 501. ing. Since the mounting plate 500 and the dam rib 501 are provided, and the water collecting chamber 400 is formed so as to surround the mounting plate 500 and the dam rib 501, the structure is simple, and the working and forming are easy.

  Since the water collecting chamber 400 is located at the center of the mounting plate 500, the center of gravity of the dam device is more likely to overlap the center, and the displacement is reduced.

  The dam rib 501 is formed in an annular shape, and an annular water collecting chamber 400 is formed so as to be surrounded by the dam rib 501 and the mounting plate 500.

  Further, the dam rib 501 is provided to be inclined. By providing the obstruction rib 501 in an inclined shape, the amount of obstruction can be increased as much as possible, which is more convenient for use.

  Further, the dam rib 501 is gradually contracted from the top to the bottom in the direction of the central axis of the water collecting chamber 400 so that the diameter of the upper opening becomes larger, which is more convenient for collection.

  Further, the bottom outer wall of the inner tank 200 has a curved surface, and a certain interval is provided between the dam rib 501 and the curved surface of the inner tank 200.

  Further, the horizontal projection of the inner tank 200 covers the horizontal projection of the water collecting chamber 400. By allowing the horizontal projection of the inner tank 200 to cover the horizontal projection of the water collecting chamber 400, the distance between the water collecting chamber 400 and the housing 100 is increased, and the water collection for the housing 100 is performed. Since the collision of the chamber 400 is prevented, the damage of the water collecting chamber 400 is reduced. In addition, since the water collecting chamber 400 is small, it is more convenient to attach other devices to the bottom of the housing 100.

  The horizontal projection of the inner tank 200 may be smaller than the horizontal projection of the water collection chamber 400 so that more water can be collected.

  Further, a drain pipe 401 is provided on the mounting plate 500. One end of the drain pipe 401 communicates with the water collecting chamber 400, and the other end communicates with the outside of the washing machine, or communicates with the entire drain pipe of the washing machine to discharge water. By providing a drain pipe 401 for discharging the water in the dam structure in the water collecting chamber 400, when the water is discharged to the water collecting chamber 400, the water in the water collecting chamber 400 is discharged through the drain pipe 401.

  Further, a first drain port 201 and a first drain pipe 202 communicating with the first drain port 201 are provided in the tank wall of the inner tank 200. The water outlet 203 of the first drain pipe 202 is provided above the upper opening of the water collecting chamber 400. Each of the first drain port 201 and the first drain pipe 202 has a plurality, and each first drain port 201 may correspond to the first drain pipe 202, or the plurality of first drain ports 201 may be one. It may correspond to the first drain pipe 202. When the washing machine executes the dehydration program, the water shaken off by the action of the centrifugal separation of the washing tub 206 enters the first drainage pipe 202 via the first drainage port 201, and The water is discharged to the water collecting chamber 400 through the water outlet 203 of the drain pipe 202. As a result, water is prevented from overflowing in all directions.

  The water outlet 203 of the first drain pipe 202 is provided above the upper opening of the water collecting chamber 400. By connecting the water outlet 203 with the dam structure, water enters the first drain pipe 202 through the first drain 201 during dehydration, and is discharged to the water collecting chamber 400 through the water outlet 203. It is blocked so that water does not overflow. The water outlet 203 is provided above the upper opening of the water collecting chamber 400 surrounded by the dam rib 501, and the water discharged from the water outlet 203 falls directly into the water collecting chamber 400. The structure is simpler and the water collecting effect is better without adding any additional members.

  Further, the inner tub 200 further includes a second drain port 204 for discharging water in the inner tub 200 to the water collecting chamber 400 when dewatering and / or shaking off water. A sealing device 205 is provided between the second drain port 204 and the water collecting chamber 400.

  Further, the second drain port 204 is provided above the upper opening of the water collecting chamber 400, and the sealing device 205 is provided below the second drain port 204.

  The second drain port 204 is provided, and the sealing device 205 opens the second drain port 204 at the time of dehydration and / or swinging of water, whereby water in the inner tank 200 is directly discharged to the dam structure. The water is blocked by the blocking rib 501 so as not to overflow, and is discharged from the washing machine through the drain pipe 401. Further, at the time of washing, the sealing device 205 seals the second drain port 204 to hold the water in the inner tub 200 in the inner tub 200 and perform the washing.

  The washing machine is a pulsator washing machine.

  The sealing device 205 includes a valve body 205-1 and an electromagnetic device 205-2 provided below the valve body 205-1. The electromagnetic device 205-2 is electrically connected to the control device of the washing machine. When the washing machine is in the washing state, the valve body 205-1 seals the second drain port 204 to prevent the water in the inner tub 200 from being discharged. Further, when the washing machine is in a draining or dewatering state, the electromagnetic device 205-2 controls the valve body 205-1 to move downward, and opens the second drain port 204, so that the water is blocked. Discharge.

  The mounting plate 500 is provided with a positioning device, and the bottom wall of the inner tank 200 is provided with a linking unit that cooperates with the positioning device. The linking portion may be a positioning groove. At the time of dehydration and / or shaking off of water, the positioning device separates from the coordination unit, and the inner tub 200 rotates according to the output shaft 303. When the washing machine is in the washing state, the positioning device cooperates with the coordination unit, and the inner tub 200 engages with the mounting plate 500. Then, the valve body 205-1 is directly opposed to the second drain port 204 and the second drain port 204 is sealed, thereby preventing the water in the inner tank 200 from being discharged. The output shaft rotates the pulsator in the washing machine.

  Further, the mounting plate 500 is provided between the inner tank 200 and the driving device 300. The lower part of the mounting plate 500 is fixedly connected to the housing of the driving device 300. By providing the mounting plate 500 between the inner tank 200 and the driving device 300, the water in the inner tank 200 drops by its own weight and can automatically flow into the dam structure. Further, since the mounting plate 500 is provided above the driving device 300, water is isolated from the driving device 300, and damage to the driving device 300 due to water is prevented.

  The driving device 300 includes a motor 301. A deceleration clutch device 302 is provided above the motor 301, and a lower portion of the mounting plate 500 is fixedly connected to the deceleration clutch or the housing of the motor 301.

  As a connection method between the mounting plate 500 and the driving device 300, the mounting plate 500 and the output shaft 303 of the driving device 300 may be connected via a bearing.

  Further, the output shaft 303 of the reduction clutch penetrates through the mounting plate 500 and is connected to the inner tank 200 to drive the inner tank 200 to rotate. The mounting plate 500 and the output shaft 303 of the driving device 300 are connected via a bearing.

  As shown in FIGS. 1 and 2, the washing machine includes a housing 100, a washing tub 206 provided in the housing 100, and a driving device 300. The output shaft 303 of the driving device 300 is connected to the washing tub 206 and drives the washing tub 206 to rotate. The washing machine further includes a suspension type vibration damping member 600 and a mounting member 700 provided below the washing tub 206. The driving device 300 is mounted on the mounting member 700. One end of the suspension type vibration damping member 600 is connected to the housing 100, and the other end is connected to the mounting member 700.

  The mounting member 700 is provided below the washing tub 206, and the suspension type vibration damping member 600 is mounted on the mounting member 700. Since the mounting member 700 is lower than the position of the washing tub 206, the height of the mounting portion 701 in the vertical direction is reduced. Therefore, the inclination angle θ between the mounted suspension type vibration damping member 600 and the side wall of the housing becomes small, and the space occupied by the suspension type vibration damping member 600 is reduced. When the structure is suspended between the washing tub 206 and the housing 100, the diameter of the washing tub 206 can be increased without increasing the volume of the housing 100, and the purpose of increasing the capacity is realized.

  The washing tub 206 may be a washing tub 206 having only the inner tub 200, and the inner tub 200 may be used for water injection and washing, or may be a washing tub 206 having the inner tub 200 and an outer tub.

  Further, the mounting member 700 includes a mounting portion 701 to be mounted on the suspension type vibration damping member 600. The mounting portion 701 is lower than the bottom of the washing tub 206.

  Since the mounting portion 701 is lower than the bottom of the washing tub 206, it does not occupy the space between the washing tub 206 and the housing 100. Therefore, the diameter of the washing tub 206 can be increased, and the capacity can be increased.

  Further, the mounting section 701 is located below the bottom of the washing tub 206. Since the mounting portion 701 is provided lower than the bottom of the washing tub 206, when the suspension type vibration damping member 600 and the mounting portion 701 are assembled, the mounting portion 701 is formed between the suspension type vibration damping member 600 and the housing 100. The angle of inclination is small. That is, since the suspension type vibration damping member 600 and the inner wall of the housing 100 are more closely contacted, a more sufficient space is held in the washing tub 206. Therefore, the purpose of increasing the capacity by increasing the diameter of the washing tub 206 can be realized.

  Further, the horizontal projection of the mounting portion 701 is located outside the horizontal projection of the washing tub 206.

  Since the mounting portion 701 is provided below the bottom of the washing tub 206 and does not occupy the space between the washing tub 206 and the housing 100, the mounting portion 701 does not collide with the washing tub 206. Assuming this, the mounting portion 701 is extended in the horizontal direction to the outside of the tub wall of the washing tub 206 such that the horizontal projection of the mounting portion 701 is located outside the horizontal projection of the washing tub 206. . Accordingly, the mounting space for the suspension type vibration damping member 600 is further reduced, so that the mounting space for the washing tub 206 is increased, and the capacity of the washing tub 206 is increased.

  Further, the output shaft 303 penetrates the mounting member 700 and is connected to the washing tub 206, and drives the washing tub 206 to rotate. The mounting member 700 and the output shaft 303 are connected via a bearing.

  The mounting member 700 may be fixedly connected to the housing of the driving device 300 such that the mounting member 700, the driving device 300, and the washing tub 206 are relatively independent units. The mounting member 700 is fixedly connected to the housing of the driving device 300 so that the mounting member 700, the driving device 300, and the washing tub 206 are relatively independent and united, and is connected to the output shaft 303 via a bearing. May be.

  The mounting member 700 is connected to the output shaft 303 via a bearing so that the mounting member 700, the driving device 300, and the washing tub 206 are relatively independent and united, and / or the housing of the driving device 300. It may be fixedly connected. Further, the vibration of the mounting member 700 is reduced by the vibration damping member, and the vibration of the washing tub 206 and the driving device 300 are further reduced, so that a good vibration damping effect is realized.

  The mounting member 700 has a centrally symmetric structure. Further, there are a plurality of the suspension type vibration damping members 600, and the plurality of the suspension type vibration damping members 600 are uniformly distributed over the entire circumference of the mounting member 700.

  By making the mounting plate 500 have a centrally symmetric structure, the possibility that the entire center of gravity of the mounting plate 500, the washing tub 206, and the motor 301 is shifted is reduced, and a better vibration damping effect is realized. In addition, by making the mounting plate 500 circular, the driving device 300 can be easily mounted, and the structure becomes more stable.

  As shown in FIGS. 1 and 2, in the present embodiment, the embodiment 3 is further limited. The mounting member 700 in this embodiment is a flat circular mounting plate 500, and the diameter of the mounting plate 500 is larger than the diameter of the washing tub 206. The mounting plate 500 is provided below the washing tub 206, and the lower end of the suspension type vibration damping member 600 is assembled to the periphery of the mounting plate 500. As a result, the connection between the suspension type vibration damping member 600 and the mounting plate 500 is located at the lower part of the washing tub 206 and at the outside of the washing tub 206 in the circumferential direction. That is, since the mounting portion 701 is positioned diagonally below the bottom of the washing tub 206, the suspension space of the suspension type vibration damping member 600 is reduced. Therefore, the space held for the washing tub 206 increases without increasing the volume of the housing 100.

  The driving device 300 is mounted below the mounting plate 500. An output shaft 303 of the driving device 300 passes through the mounting plate 500 and is connected to the mounting plate 500 via a bearing.

  There are four suspension type vibration damping members 600, which are uniformly distributed over the entire circumference of the circular mounting plate 500.

  The damping member includes a suspension rod 602 and a damping unit 601 that generates a damping force. One end of the suspension rod 602 is fixed to an upper portion of the housing 100, and the other end penetrates the mounting part 701 and is connected to the vibration damping unit 601.

  Since the vibration suppression unit 601 is located below the mounting plate 500, the vibration suppression unit 601 does not occupy the space between the housing 100 and the washing tub 206 in the horizontal direction. Therefore, the situation where the vibration suppression unit 601 prevents the capacity of the washing tub 206 from increasing is reduced.
