Description

a washing machine

technical field

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

Background technique

A washing machine is designed as a device for washing clothes by using electricity, in general, a washing machine includes: a tub for containing washing water; a rotating tub, which is rotatably installed inside the tub; a pulsator, which is rotatably installed in the rotating tub The bottom of the ; motor and clutch, configured to rotate the rotating barrel and pulsator. When the rotary tub and the pulsator are rotated in a state where laundry and detergent are introduced into the rotary tub, the pulsator agitates the wash water together with the laundry introduced into the rotary tub, thereby removing stains from the laundry.

In order to increase the washing capacity of the washing machine, a larger rotating tub is required, that is, the height or diameter of the rotating tub needs to be increased. If the rotating bucket has a larger size, the bucket accommodating the rotating bucket and the cabinet accommodating the bucket also need to be enlarged as the rotating bucket increases.

The increase of the casing corresponding to the appearance of the washing machine is limited by the space of the area where the washing machine is installed. The general user's home has limited space for the washing machine. It is not realistic to increase the washing machine casing to achieve the purpose of increasing the capacity of the washing tub. On the premise of not increasing the casing of the washing machine, increasing the capacity of the rotating tub has become a major problem for designers.

Patent CN201610210904.6 provides that the present invention discloses a non-porous inner tub washing machine, which relates to the technical field of washing machines, in order to solve the problem of easy splashing of water when draining water from the top of the inner tub and bacteria breeding in the outer tub under the premise of saving water, and can reduce the Invented at the cost of washing machines. A non-porous inner tub washing machine comprises an inner tub and an outer tub, a water collecting ring is arranged at the mouth of the inner tub, the water collecting ring comprises a water collecting cavity, a water collecting port and a drain port communicating with the water collecting cavity, The water collecting port faces the inside of the inner tub, the drain port faces the gap between the inner tub and the outer tub, and the drain port is connected with a drain pipe, and the drain pipe extends downward to the bottom of the outer tub, This structure achieves the water collection effect, but since the outer eaves of the outer tub extend above the inner tub, the inner tub is easily collided with the outer tub to cause damage, and the existence of the outer eaves is not conducive to increasing the volume of the inner tub.

In addition, during the working process of the washing machine, since the motor drives the inner tub to rotate, in the case of high rotational speed or sudden stop, etc., it is easy to hit the tub, causing the washing machine to shift, making a large noise. In order to reduce vibration, shock-absorbing devices such as shock-absorbing suspension booms and shock-absorbing pads are installed on the washing machine. In an existing washing machine, in order to buffer the impact of the tub assembly on the box body and reduce vibration, a shock-absorbing pad is often arranged on the box body. When the height of the washing tub decreases, it is necessary to move down the position of the correspondingly pasted shock-absorbing pad, which is unfavorable for the actual operation of the production line. At the same time, after adding clothes and water in the tub, the distance of each downward movement is uncertain, and the shock-absorbing pad is pasted. The position on the box is fixed. When the outer barrel hits the box, it will not necessarily hit the part of the box with the shock-absorbing pad, which may affect the effective area of the shock-absorbing pad, resulting in the anti-collision effect of the shock-absorbing pad. Not good, can not play a very good buffering effect.

The present invention has been made in view of this.

Example 1

As shown in FIG. 1-FIG. 6, this embodiment provides a washing machine, including a box body 100, an inner tub 200 disposed in the box body 100 for holding water, and a driving device 300 for driving the inner tub 200 to rotate, and also A water collecting device for collecting the water discharged from the inner tub 200 is included, the water collecting device is located outside the inner tub 200, and a shock absorbing device 800 is also provided on the outer wall of the water collecting device and/or on the outer wall of the inner tub 200 .

In this embodiment, the inner tub 200 of the washing machine is a non-porous inner tub 200, and only the upper part of the inner tub 200 is provided with a dehydration hole for throwing out the escaping water, and the inner tub 200 can be used to hold water. The water collecting device can be an outer tub 900, preferably the height of the tub opening is lower than the tub opening of the inner tub 200 of the washing machine, more preferably, the height of the tub opening of the outer tub 900 is slightly higher than the tub bottom of the inner tub 200. Alternatively, the water collecting device of the washing machine can also be an improved structure provided separately, which can further play the role of expanding the volume of the washing machine.

By setting the water collecting device, on the one hand, when the water is discharged from the inner tub 200, the water thrown out during dehydration in the inner tub 200 is collected by the water collecting device to prevent the overflow of water, on the other hand, the whole water collecting device can be arranged in the inner tub The lower part of the barrel bottom of 200. Since the water collecting device is located below the inner tub 200 as a whole, the water collecting device does not occupy the space between the inner tub 200 and the box body 100 , does not limit the expansion of the inner tub 200 , and provides ample space for the expansion of the inner tub 200 .

In a further solution, the water collecting device includes a water collecting chamber 400 with an upper opening, the inner tub 200 communicates with the upper opening of the water collecting chamber 400 , and a shock absorbing device 800 is provided outside the side wall of the water collecting chamber 400 .

By setting the water collecting cavity 400 , the water discharged from the dehydration in the inner tub 200 can be collected, and the water discharged from the inner tub 200 can be blocked. The side wall of the water collection chamber 400 can be flush with the outer wall of the inner tub 200 and does not occupy the space between the inner tub 200 and the box 100; the upper end of the side wall of the water collection chamber 400 can also be lower than the bottom of the inner tub 200, so that The water collecting chamber 400 is located below the bottom of the inner tub 200 as a whole. Further, the side wall of the water collecting chamber 400 does not have a structure between the inner tub 200 and the box body 100, which can greatly increase the diameter of the inner tub 200 and better realize the inner tub. The expansion of the 200 also does not need to set a certain safety distance between the inner tub 200 and the water collecting device, so as to prevent the inner tub 200 from colliding with the water collecting device and causing damage. At the same time, the possibility of the water collecting device hitting the box body 100 is further reduced.

The damping device 800 is provided outside the side wall of the water collecting cavity 400, which can further reduce the damage of the washing machine accidentally hitting the tub.

Embodiment 2

As shown in FIGS. 5 and 6 , this embodiment is a further limitation of Embodiment 1. In this embodiment, the water collecting device includes a mounting plate and a water retaining rib 501 disposed on the mounting plate. The mounting plate is connected to the mounting plate. The water retaining rib 501 encloses the water collecting cavity 400 , and a shock absorbing device 800 is provided on the outer wall of the water retaining rib 501 .

By arranging the mounting plate 500 and the water retaining rib 501, and enclosing the two to form the water collecting cavity 400, the structure is simple and convenient for processing and forming. The water retaining rib 501 is the side wall of the water retaining chamber 400, has a certain height, is relatively close to the box body 100, and has the possibility of hitting the box body 100. The damping device 800 is arranged on the outer wall of the water retaining rib 501, which can The vibration when the water retaining rib 501 accidentally hits the box body 100 is reduced to avoid damage. In the production process, the damping device 800 can be directly fixed on the retaining rib, and there is no need to measure the position of the box body 100 and the retaining rib. The shock absorbing device 800 is able to exert its maximum effect.

The water collecting cavity 400 is located in the middle of the mounting plate 500, so that the center of gravity of the water blocking device is more easily coincident with the center, and the offset is reduced.

The water retaining rib 501 is annular, and the water retaining rib 501 and the mounting plate 500 are enclosed to form an annular water collecting cavity 400 .

In a further solution, the shock absorbing device 800 is arranged on the water retaining rib 501 where the distance from the inner wall of the box body 100 is the smallest.

In order to achieve a good water accumulation effect and reduce the space occupied, the water retaining ribs 501 need to be arranged in a ring shape with the bottom of the inner tub 200; and the box body 100 of the washing machine is generally square, so the different positions of the water retaining ribs 501 are different from the inner wall of the box body 100. The distances are not the same. The place where the tangent of the outer circumference of the annular water retaining rib 501 is parallel to the side wall of the box body 100 is the part where the distance between the water retaining rib 501 and the inner wall of the box body 100 is the smallest. The shock absorbing devices 800 can be arranged at intervals, and are only arranged on the water retaining ribs 501 where the distance from the inner wall of the box body 100 is the smallest, so as to reduce the cost and have a good shock absorbing effect. Alternatively, in addition to disposing the shock absorbing device 800 on the part with the smallest distance from the inner wall of the box body 100, the shock absorbing device 800 can also be installed in other parts, or all of them can be installed to achieve more directional shock absorbing effects.

The damping device 800 on the water collecting device and on the inner tub 200 can be installed on the water collecting device, or on the outer wall of the inner tub 200, or on the water collecting device according to the positional relationship between the water collecting device and the inner tub 200. Both the device and the outer wall of the inner tub 200 are installed in order to achieve the best shock absorption effect with low cost. If you can set it as follows:

Case 1: When the projection of the inner tub 200 in the horizontal direction covers the projection of the water collecting cavity 400 in the horizontal direction, the shock absorber 800 is disposed on the outer wall of the inner tub 200 .

By covering the projection of the inner tub 200 in the horizontal direction with the projection of the water collection cavity 400 in the horizontal direction, the interval between the water collection cavity 400 and the box body 100 is increased, the collision of the water collection cavity 400 with the box body 100 can be prevented, and the The water collecting chamber 400 is damaged; at the same time, the water collecting chamber 400 is small, which is more convenient for the installation of other devices at the bottom of the box body 100 .

When the projection of the inner tub 200 in the horizontal direction covers the projection of the water collecting cavity 400 in the horizontal direction, the water collecting device is completely located at the bottom of the inner tub 200, and the diameter is smaller than that of the inner tub 200. Compared with the two, the inner tub 200 has a larger diameter and a higher height , it is easier to hit the box body 100 when it vibrates. Therefore, the shock absorber 800 can be arranged on the outer wall of the inner tub 200, and the position closest to the box body 100 can be set in blocks, or it can be set continuously, or it can be as large as possible. area settings. The side wall of the water collecting cavity 400 is less likely to hit the box body 100, so it may not be provided.

Case 2: When the projection of the inner tub 200 in the horizontal direction is located inside the projection of the water collecting cavity 400 in the horizontal direction, the shock absorber 800 is arranged on the outer wall of the inner tub 200 and the outer wall of the water retaining rib 501 .

When the projection of the inner tub 200 in the horizontal direction is located inside the projection of the water collecting cavity 400 in the horizontal direction, the diameter of the side wall of the water collecting chamber 400 , such as the water retaining rib 501 is larger than the diameter of the inner tub 200 and is closer to the box 100 , the possibility of an accident of hitting the barrel is high, and the height of the inner barrel 200 is relatively high. When the inner barrel 200 vibrates, the swing range of the inner barrel 200 is also relatively large, and the accident of hitting the barrel may also occur. Therefore, the damping device 800 may be provided on both the outer wall of the inner tub 200 and the outer wall of the water retaining rib 501 , or the damping device 800 may be provided only on the outer wall of the water retaining rib 501 .

By arranging the water retaining ribs 501 in an inclined shape, the water collection amount can be increased to the maximum extent, which is more convenient to use; at this time, the distance between the upper part of the water retaining ribs 501 and the box body 100 at the same position is greater than the distance between the middle part and the lower part and the box body 100 At this time, it is necessary to set a shock absorber 800 on the upper part of the outer side wall of the water retaining bar 501 to achieve the effect of reducing vibration.

Alternatively, the water retaining rib 501 is arranged vertically, and the damping device 800 is arranged in the middle and/or upper part of the outer periphery of the water retaining rib 501 . When the water retaining bar 501 is vertically arranged, the process is simple and the preparation is easy. At this time, the distance between the water retaining bar 501 at the same position and the box body 100 is the same.
