Description

Wave washing machine

Technical field

The invention belongs to the field of washing machines, and in particular to a pulsator washing machine.

Background technique

The washing machine is designed as a device for washing laundry by using electricity. Generally, the washing machine includes: a tub for accommodating washing water; a washing tub rotatably installed inside the tub; and a pulsator rotatably mounted in the washing tub The bottom; the motor and the clutch are configured to rotate the wash tub and the pulsator. When the pulsator rotates to agitate the laundry and the washing water in the washing tub, the stain on the laundry is removed.

In order to increase the washing capacity of the washing machine, a larger washing tub is required, that is, it is necessary to increase the height or diameter of the washing tub. If the size of the washing tub is increased, the tub accommodating the washing tub and the cabinet accommodating the tub also need to increase as the washing tub increases.

The increase of the casing corresponding to the appearance of the washing machine is limited by the space of the area in which the washing machine is installed. The space for installing the washing machine in the general user's home is limited, and the purpose of increasing the capacity of the washing machine to increase the capacity of the washing tub is not realistic, how is it not? Under the premise of increasing the casing of the washing machine, increasing the capacity of the washing tub becomes a major problem for the designer.

The purpose of capacity expansion can be achieved by modifying the structure of the barrel assembly, but in the washing process, when the rotation speed of the washing tub is reduced to a certain range (generally lowered to the vicinity of the resonance point), the washing tub is severely shaken in the horizontal direction, and it is easy to cause washing. The barrel collides with the cabinet, causing damage to the washing tub and/or the cabinet. This problem can be achieved by setting different damping devices to reduce the probability that the barrel assembly will hit the box during the washing process, and to enhance the anti-biasing ability of the barrel assembly, especially the vibration at low speed over the resonance point.

On the basis of the suspension parts of the existing washing machine, the damping device can help the barrel assembly to smoothly pass the low-speed resonance point, but a new problem arises: the damping device is connected to the barrel assembly at one end and the connection box at the other end. Body, this will transmit the vibration of the barrel assembly to the box, causing the box to shift.

The cushioning device 800 may be disposed at least between the bottom damper device 703 and the tank 100, or between the bottom damper device 703 and the washing tub assembly 101, or at the same time. The cushioning device 800 can further buffer the vibration transmitted from the washing tub assembly 101 to the casing, avoiding displacement of the casing, reducing noise, and enhancing the user experience.

In a further aspect, the washing tub assembly 101 includes a washing tub and a water collecting device 102. During the washing process, the washing tub is a water tub, and at least a portion of the water collecting device 102 is disposed at a lower portion of the washing tub to collect water discharged from the washing tub; One end of the bottom damper device 703 is connected to the water collecting device 102, and one end is connected to the box body; at least a buffer device 800 is disposed between the bottom damper device 703 and the inner wall of the tank.

The washing tub 200 of the washing machine in this embodiment is a non-porous washing tub 200, and only a dewatering hole for taking out the desorbed water is provided in the upper portion of the washing tub 200, and the washing tub 200 can be used for holding water. The water collecting device 102 may be an outer tub, preferably the barrel mouth height is lower than the washing tub 200 mouth of the washing machine. More preferably, the height of the tub mouth of the outer tub is slightly higher than the bottom of the tub 200 of the washing tub 200. Alternatively, the water collecting device of the washing machine may be a separately provided improved structure, and may further function to expand the volume of the washing machine.

By providing the water collecting device, on the one hand, when the water is discharged from the washing tub 200, the water that is taken out during the dehydration in the washing tub 200 is collected by the water collecting device to prevent the water from overflowing, and on the other hand, the water collecting device can be integrally disposed. Outside the bottom of the tub of the washing tub 200. Since the water collecting device is located below the washing tub 200 as a whole, the water collecting device does not occupy the space between the washing tub 200 and the tank 100, and does not have a limiting effect on the expansion of the washing tub 200, thereby providing ample space for the expansion of the washing tub 200. .

One end of the bottom damper device 703 is connected to the water collecting device, and one end is connected to the tank body. When the device vibrates with the rotation of the washing tub, the vibration energy is absorbed, and part of the energy is transmitted to the tank connected thereto.

The side wall of the water collecting chamber 400 may be flush with the outer wall of the washing tub 200, and does not occupy the space between the washing tub 200 and the tank 100; the upper end of the side wall of the water collecting chamber 400 may also be lower than the barrel of the washing tub 200. The bottom of the water collecting chamber 400 is located below the bottom of the tub 200, further preventing the side wall of the water collecting chamber 400 from having a structure between the washing tub 200 and the tank 100, which can greatly increase the barrel diameter of the washing tub 200. The expansion of the washing tub 200 is better realized, and a certain safety distance is not set between the washing tub 200 and the water collecting device to prevent the washing tub 200 from colliding with the water collecting device to cause damage. At the same time, the possibility that the water collecting device hits the tank 100 is further reduced.

One end of the bottom damper device 703 may be connected to the outer wall of the water collecting chamber, may be connected to the outer wall of the side portion, or may be connected to the outer wall of the bottom portion, and the preferred solution is connected with the outer wall of the bottom portion, and the bottom portion has a large area and is easy to install; It is located under the water collecting chamber and does not occupy the space on the side of the water collecting chamber, which is beneficial to install other structures, such as suspension shock absorbers, to achieve the shock absorption effect. Preferably, the bottom damper device 703 is connected to the inner wall of the lower part of the box body, and the occupied space is small to avoid other structures. At this time, the buffer device 800 can reduce the energy transmission, and ensure that the vibration of the whole machine is small and no displacement occurs.

Preferably, both ends of the bottom damper device are respectively connected to the bottom outer wall of the water collecting chamber and the bottom of the tank body. Since the washing tub and the water collecting device generate a composite vibration in the longitudinal direction and the horizontal direction during the washing process, a torsional force is generated, and therefore, the bottom shock absorbing device 703 is movably connected to the bottom outer wall of the water collecting chamber and the inner wall of the bottom of the tank. The torque of the bottom damper 703 to the water collecting device and the box body is overcome, and the damage of each component is reduced.

The bottom damper device 703 of the present solution is preferably a free-running damper, which generates a large damping force at a low speed, and generates a small damping force at a high speed because it is an idle stroke, which facilitates the smooth passage of the washing tub assembly 101 through different periods. Resonance point. Larger resistance at low speeds facilitates the passage of low-speed resonance points, and lower resistance at high speeds facilitates high-speed resonance points while preventing vibration from being transmitted to the cabinet. The shock absorber may be an inflatable shock absorber or a hydraulic shock absorber, and the shock absorber 705 is hingedly connected to the mounting brackets 706 at both ends. The mounting bracket 706 is used to securely mount the bottom damper 703. In order to achieve a good fixing effect and vibration isolation effect, the buffer device 800 can be a cushion pad disposed between the mounting bracket 706 fixed to the bottom of the box body and the inner wall of the box body, absorbing the vibration energy of the shock absorber and avoiding being transmitted to the box body. .

In a further aspect, the bottom of the box is provided with a damper mounting plate 900, and the mounting bracket 706 at one end of the bottom damper 703 is fixed on the damper mounting plate 900, and the buffer device 800 is disposed on the mounting bracket 706 and the damper mounting Between the boards 900. The bottom of the box body may be a box base, and the shock absorbing mounting board 900 is disposed on the box base, so that a larger installation area can be provided, and the shock absorber can be better fixed.

In a further aspect, the cushioning device 800 includes a cushion for damping, and the cushion is disposed between the end of the bottom shock absorbing device and the casing.

The area of the cushion pad may also be smaller than the area of the joint between the bottom shock absorbing device 703 and the box body, and is hidden between the bottom buffer device and the box body. The area of the cushion pad may also be greater than or equal to the area of the joint and increase the buffer area.

Preferably, the area of the cushion is not less than the area of the bottom shock absorbing device 703 and the joint of the box. The cushioning device 800 is a sheet-shaped cushion that is easily fixed between the bottom damper 703 and the inner wall of the casing. The cushion may be made of a flexible material or may have a deformed structure to facilitate absorption of vibration transmitted by the bottom damper 703.

Preferably, the cushion is a rubber pad or a spring pad, which is convenient for installation and can provide vibration isolation.

In a further aspect, the bottom damper device is disposed at an angle to the damper mounting plate, and the mounting bracket at one end of the bottom damper device is fixed on the damper mounting plate, and the buffer device is disposed in parallel on the mounting bracket and the damper mounting plate. Between, it is conducive to installation and shock absorption.

Further, the shock absorbing mounting plate 900 is horizontally disposed, and the mounting bracket 706 at one end of the bottom damper device 703 is vertically disposed with the damper mounting plate 900 and fixed on the damper mounting plate 900, and the buffer device 800 is horizontally installed. The bracket 706 is between the damper mounting plate 900.

The mounting bracket 706 at one end of the damper 705 is vertically disposed with the damper and rotating plate, which can ensure a large contact area and a firm installation, and the buffer device 800 is sandwiched between the vertically disposed mounting bracket 706 and the damper rotating plate, It is prone to positional shift, and it can also transmit energy of the largest area, absorb energy better, provide vibration isolation, and is not easily damaged.

Further, the distance from the bottom shock absorbing device 703 to the bottom of the tank to the axis of the washing tub is greater than the distance from the joint of the bottom damper 703 and the bottom outer wall of the water collecting chamber to the axis of the washing tub. The bottom damper device 703 of the present scheme is inclined from the bottom to the top, and is inclined by the box body toward the central axis of the washing tub, and can both function as a water collecting device and a vibration damping function when vibrating.

In a further solution, in order to achieve a better shock absorbing effect, the bottom damper device 703 is provided in plurality, and the plurality of bottom damper devices 703 are symmetrically disposed around the axis of the washing tub; or the axis spacing around the washing tub A distribution device is provided at each of the joints of the bottom shock absorbing devices 703 and the casing. Preferably, the plurality of bottom dampers 703 are evenly spaced around the axis of the wash tub.

The plurality of bottom damper devices 703 are symmetrically disposed about the axis of the washing tub, and the two sides are opposite to each other, so that the water collecting device can be balanced by force, and the plurality of bottom damper devices 703 uniformly disperse and absorb the energy of the vibration to achieve better reduction. Shock effect. The distribution of the circumference of the washing tub is evenly distributed, and the water collecting device as a whole can be balanced by force, thereby reducing the possibility of the washing tub assembly 101 colliding with the tank. In the above two modes, the buffering device 800 is disposed at the connection between each of the bottom damper devices 703 and the box body, and the vibration is also absorbed by the respective buffer devices 800 while uniformly and uniformly absorbing the vibration energy, and the box is not affected. Body, avoid box displacement.

A further solution further includes suspending the shock absorbing member, the upper end of the suspension damper member is connected to the upper portion of the box body, and the lower end is connected to the washing tub assembly 101.

In the washing tub assembly 101, the water collecting device is disposed below the washing tub. The water collecting device may be an outer tub, and the bucket mouth is lower than one-half of the height of the washing tub; the water collecting device may also be a separately provided improved structure. Specifically, the water collecting device includes a mounting plate and is disposed on the mounting plate. The water retaining rib and the water retaining rib are annularly arranged to surround the water collecting chamber, and the upper opening of the water collecting chamber communicates with the washing tub.

By installing the mounting plate 500 under the washing tub 200, the suspension damper 600 is mounted on the mounting plate 500. Since the mounting plate 500 is positioned lower than the washing tub 200, the longitudinal height of the mounting portion is lowered, so that after installation The inclination angle θ between the suspension damper 600 and the side wall of the casing is reduced, thereby reducing the occupied space of the suspension damper 600, when the structure is suspended from the washing tub 200 and the casing 100. In the meantime, it is possible to increase the diameter of the washing tub 200 without increasing the volume of the casing 100, thereby achieving further expansion.

Specifically, there are four suspension damping members 600, which are evenly distributed around the water collecting device.

The suspension damper 600 includes a boom 602 and a damper unit 601 for generating a damping force. The washing tub assembly 101 is provided with a mounting portion which is disposed at a lower portion of the lower opening of the outer tub and protrudes outwardly; or the mounting portion is located at the outer periphery of the mounting plate.

In the first embodiment, the upper end of the boom 602 is fixed to the upper portion of the casing 100, and the lower end is connected to the damper unit 601 through the mounting portion.

The damper unit 601 is located at a lower portion of the mounting plate 500, so that the damper unit 601 does not occupy the space between the box 100 and the washing tub 200 in the horizontal direction, and further reduces the hindrance of the damper unit 601 from expanding the washing tub 200.

In the second embodiment, the upper part of the box body 100 is provided with a mounting seat. The lower end of the boom 602 is connected to the mounting portion, and the other end is connected to the shock absorbing unit 601 through the mounting seat.

The mounting plate 500 may be a flat plate or a structure having a low intermediate edge and a low edge, for example, including an annular edge plate, a circular center plate, and a connecting riser for connecting the edge plate and the center plate, and the cross section forms an "Ω" shape.

The driving device is disposed under the water collecting device, and the output shaft of the driving device is connected to the washing tub through the water collecting chamber. The mounting plate 500 can also be fixedly connected to the casing of the driving device. Of course, the mounting plate can also be connected to the casing and the output shaft through bearings at the same time. Preferably, the driving device is mounted on the lower part of the mounting plate.

Further, the motor is provided with a deceleration clutch 302, and the output shaft of the deceleration clutch is connected with the washing tub to drive the washing tub to rotate.

Thus, in the pulsator washing machine of the present embodiment, when the washing tub assembly 101 vibrates, it is subjected to an upward thrust or a downward pulling force of the bottom damper device 703, and is subjected to the force of the suspension damper. The bottom damping device 703 and the suspension damping member are alternately arranged, and a better damping effect is achieved by the combined action of the two.

The suspension damping member plays the role of vibration reduction in the whole process of the washing machine operation, and the bottom damping device is an idle stroke shock absorber, which mainly generates a large damping force at a low speed, and is generated by an idle stroke at a high speed. The smaller damping force facilitates the smooth passage of the washing tub assembly 101 through the resonance points of different time periods. The suspension damping member and the bottom damping device cooperate with each other to work in stages and cooperate with each other to achieve better vibration damping effect.

The mounting plate may be a single-layer plate structure or a mounting member including a plurality of structures. For example, specifically, the mounting member 700 includes a mounting large plate 700-1 connected to the suspension damper 600 and a mounting small plate 700-2 connected to the bottom damper 703, the mounting slab 700-1 and the mounting small plate The 700-2 is connected by ribs to enhance the strength of the mounting. The rib spacing is set to enhance the effect. Since the bottom wall of the washing machine case 100 needs to be provided with a reinforcing structure and other components to be installed, the diameter of the large plate 700-1 is generally designed to be larger than the diameter of the mounting small plate 700-2, providing space for installation of other components. Separate settings make it easier to use the space below 700.

Further, the washing machine further includes a damper spring seat 704 disposed at a lower portion of the driving device, the upper end of the damper spring seat 704 is fixedly coupled to the driving device, and the lower end is fixedly coupled to the bottom wall of the box 100.

The damper spring seat includes a plurality of damper springs, and the damper spring seat 704 is disposed to apply a downward pulling force or an upward elastic force to the driving device, and the bottom damper device 703703 and the suspension damper member 600 are combined. The whole formed by the water collecting device, the driving device 300 and the washing tub 200 achieves a better vibration damping effect under the action of a single component.
