The washing machine mainly comprises an outer drum, an outer drum cover, an inner drum, a balance ring and a driving mechanism for driving the inner drum to rotate. Washing machines with different volumes correspondingly adopt different heights and widths of these components, so as to realize the production of washing machines with different volumes. With the continuous updating of market demand, the demand for large-volume washing machines will continue to increase. If larger-volume washing machines are to be produced, the entire set of washing machine parts needs to be re-molded, which involves a large mold opening cost and increased part cost, and the development cost is high.

[0003] In addition, the balance ring is an annular structure arranged at the top of the inner drum. Since the center of gravity of the clothes cannot be completely coincident with the center of the drum body when the clothes are put into the inner drum, the inner drum may rotate eccentrically due to uneven clothes during the dehydration operation, thereby causing impact on the box body, and even causing damage to the motor. The balance ring is filled with a balancing medium. When the inner drum rotates for dehydration and spin-drying, the balance ring compensates the eccentric force of the high-speed rotating inner drum by utilizing the hysteresis of the flow of the balancing medium in the balance ring, thereby achieving the balancing effect. However, the existing balance ring not only has insufficient strength, but also the balancing medium easily flows rapidly under the driving of the inner drum, and cannot achieve a good balancing effect.

[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings. It is hereby declared that the up, down, left, right, front, back, inner and outer words appearing in the text or about to appear in the text of the present application are only based on the drawings of the present application, and they are not the specific limitation of the present application.

[0028] Referring to Figures 1-6 The present application discloses a washing machine, comprising an outer drum 1, an inner drum, a balance ring 4 and a driving mechanism 2, wherein the inner drum is installed in the outer drum 1; the driving mechanism 2 is installed at the bottom of the outer drum 1 and connected with the bottom of the inner drum; and the balance ring 4 is installed at the top of the inner drum.

[0029] The top of the outer drum 1 is provided with a preset space, so that inner drums of different heights can be installed in the outer drum 1.

[0030] The balance ring 4 comprises an upper ring part 41 and a lower ring part 42, wherein the upper ring part 41 is arranged at the top of the lower ring part 42, a balance cavity 43 is formed between the upper ring part 41 and the lower ring part 42, and an upper reinforcing rib 411 arranged on the upper ring part 41 and a lower reinforcing rib 421 arranged on the lower ring part 42 are arranged in the balance cavity 43.

[0031] The top of the outer drum of the washing machine of the present application is provided with a preset space, so that not only relatively short inner drums but also relatively high inner drums can be matched, so that washing machines of different volumes can be produced by selecting inner drums of different heights and using other common parts, the parts of re-opening mold are reduced, the cost of mold opening is saved, the cost of parts is reduced, and thus the development cost is reduced.

[0032] ​​​In addition, the reinforcing ribs are arranged in the upper ring part and the lower ring part of the balance ring, which not only strengthens the strength of the upper ring part and the lower ring part, thereby strengthening the overall strength of the balance ring, but also prevents the balance medium from being rapidly wasted in the balance cavity, makes the balance medium flow gently, and achieves better balance effect.

[0033] The balance cavity 43 is filled with a balance medium, which is preferably brine. The outer drum 1 is provided with an outer drum opening at the top, and the inner drum is provided with an inner drum opening at the top. The outer drum opening and the inner drum opening are arranged correspondingly. The height of the inner drum opening relative to the outer drum opening will be different if inner drums of different heights are installed. If a higher inner drum is installed, the top of the inner drum may protrude out of the outer drum opening, so that the inner drum opening is higher than the outer drum opening. If a lower inner drum is installed, the top of the inner drum may be inside the outer drum, so that the inner drum opening is lower than the outer drum opening. The inner drum side wall is provided with a water passing hole, and the water in the outer drum flows between the outer drum and the inner drum through the water passing hole. The driving mechanism 2 is a clutch.

[0034] Preferably, the upper reinforcing ribs 411 and the lower reinforcing ribs 421 are arranged in a staggered manner. The upper reinforcing ribs 411 are arranged in a spaced manner, and the lower reinforcing ribs 421 are arranged in a spaced manner. The upper reinforcing ribs 411 are arranged between two adjacent lower reinforcing ribs 421, and the lower reinforcing ribs 421 are arranged between two adjacent upper reinforcing ribs 411. The upper reinforcing ribs and the lower reinforcing ribs are arranged in the balance cavity in an up-down manner, the balance medium is blocked by the upper reinforcing ribs and the lower reinforcing ribs, the flow speed is slow, and the balance effect is good.

[0035] Preferably, as shown in Figure 4 the outer side top end of the lower reinforcing rib 421 is higher than the inner side top end of the lower reinforcing rib 421. That is, the lower reinforcing rib has a gap, forming a guide channel, which plays a certain guiding role for the balance medium, and also plays a certain blocking role to reduce the flow speed, without forming too much resistance to cause a larger reaction force of the balance medium on the balance ring, and the balance effect is good.

[0036] More preferably, as shown in Figure 4 the outer side top end of the lower reinforcing rib 421 and the inner side top end of the lower reinforcing rib 421 are connected by an arc surface 423. That is, there is an arc surface between the outer side top end and the inner side top end of the lower reinforcing rib, which makes the balance medium pass over the top of the lower reinforcing rib more gently, without generating a larger impact, and further makes the balance effect better.

[0037] Preferably, as shown in Figure 4As shown, the bottom of the upper ring part 41 is provided with a connecting seat 412, the connecting seat 412 is provided with a connecting groove 413, the top of the lower ring part 42 is provided with a connecting strip 424, the connecting strip 424 is inserted into the connecting groove 413, and the connecting seat 412 and the connecting strip 424 are fixedly connected. The connecting strip is inserted into the connecting groove, the positions of the upper ring part and the lower ring part are relatively fixed, then the connecting strip and the connecting seat are fixed by using spin fusion or hot melting, so that the upper ring part and the lower ring part are fixedly connected, and the balance cavity is sealed, and the balance medium is prevented from leaking.

[0038] Further, as shown in the drawings, Figures 1-6 The utility model also includes the outer bucket cover installed on the top of the outer bucket 1, and the preset space is arranged in the outer bucket cover. The preset space is realized by arranging the outer bucket cover with different heights. The outer bucket cover is used not only to shield the gap between the outer bucket and the inner bucket, but also to prevent water in the outer bucket from splashing out. The outer bucket cover is matched with the inner bucket. Generally, when a low-height inner bucket is installed, a low-height outer bucket cover is correspondingly installed; when a high-height inner bucket is installed, a high-height outer bucket cover is correspondingly installed. Therefore, the preset space is arranged in the outer bucket cover, and the top of the high-height inner bucket extends into the outer bucket cover, thereby realizing the shielding of the gap by the outer bucket cover and preventing water from splashing out.

[0039] Preferably, as shown in the drawings, Figure 2 The outer bucket 1 is provided with a clamping block 11, and the outer bucket cover is provided with a clasp 51, which is clamped on the clamping block 11. The cooperation of the clamping block and the clasp facilitates the installation and positioning of the outer bucket cover and the outer bucket, and the installation operation is simple and reliable.

[0040] To further strengthen the connection between the outer bucket cover and the outer bucket, preferably, as shown in the drawings, Figure 2 The outer side wall of the outer bucket 1 is provided with a bucket fixing seat 12, the outer side wall of the outer bucket cover is provided with a cover fixing seat 52, and the bucket fixing seat 12 and the cover fixing seat 52 are fixedly connected by fasteners (not shown in the drawings). The fastener is preferably a screw. Specifically, the bucket fixing seat is provided with a threaded hole, the cover fixing seat is provided with a through hole, the fastener is inserted into the through hole and is screwed with the bucket fixing seat through the threaded hole, thereby further realizing the fixed connection of the outer bucket cover and the outer bucket, and ensuring the stability and reliability of the outer bucket cover and the outer bucket.

[0041] Preferably, as shown in the drawings, Figure 4As shown, the outer barrel 1 side wall is provided with overflow seat 13, the overflow seat 13 is provided with overflow channel 131, the inner and outer of the outer barrel 1 is communicated through overflow channel 131. Specifically, overflow seat 13 is arranged on the outer side wall of the top of outer barrel 1, and overflow seat 13 is further connected with a drain pipe. If the water level in the outer barrel is higher than the water outlet communicated with the overflow channel in the outer barrel, water will flow into the overflow channel through the water outlet, and then be discharged out of the outer barrel through the drain pipe, so as to avoid the water level in the outer barrel from overflowing out of the outer barrel opening, and limit the maximum height of the water level in the outer barrel.

[0042] Correspondingly, as shown in Figure 4 , the outer barrel cover is provided with a drain hole 53, and the overflow channel 131 and the drain hole 53 are communicated. The overflow channel and the drain hole are correspondingly arranged. When there is accumulated water on the outer barrel cover, the accumulated water can flow into the overflow channel from the drain hole and be discharged, which facilitates the cleaning of the accumulated water, and the structure is simple, the components are few, and the space is also saved.

[0043] Preferably, as shown in Figure 4 , the balance ring 4 is provided with a connecting avoidance position 422, and the balance ring 4 is installed on the top of the inner barrel through the connecting avoidance position 422. The balance ring and the inner barrel are in interference fit, and the inner barrel wall is inserted at the connecting avoidance position. The connecting avoidance position plays a limiting position role on the inner barrel, so that the relative position of the balance ring and the inner barrel is fixed. Finally, the inner barrel and the balance ring can be fixedly connected by screws, which is simple in structure and convenient to install.

[0044] It should be noted that the utility model includes at least two embodiments, and the difference between the two embodiments is that the height of the outer barrel cover and the inner barrel is different, and the other structures are the same.

[0045] The first embodiment, as shown in Figures 1-4 , the outer barrel cover is a first outer barrel cover 5a, and the first outer barrel cover 5a is installed on the top of the outer barrel 1. The inner barrel is a first inner barrel 3a, and the first inner barrel 3a is installed in the outer barrel 1. The first outer barrel cover 5a and the first inner barrel 3a are matched.

[0046] The second embodiment, as shown in Figures 5-6 , the outer barrel cover is a second outer barrel cover 5b, and the second outer barrel cover 5b is installed on the top of the outer barrel 1. The inner barrel is a second inner barrel 3b, and the second inner barrel 3b is installed in the outer barrel 1. The second outer barrel cover 5b and the second inner barrel 3b are matched.

[0047] The height of the second outer bucket cover 5b is higher than the first outer bucket cover 5a, and the height of the second inner bucket 3b is higher than the first inner bucket 3a. The washing machine with different volumes can be produced by setting the outer bucket cover and the inner bucket with different heights, that is, only the outer bucket cover and the inner bucket with different heights need to be configured, other components are universal, the number of components that need to be opened again is reduced, and the cost is reduced. The different height parameters of the outer bucket cover and the inner bucket are designed according to different volume requirements of the washing machine, which is not limited here. The washing machine with different volumes can be produced and manufactured only by matching the outer bucket cover and the inner bucket with different heights, the number of components that need to be opened is greatly reduced, and the cost is reduced.

[0048] It should be noted that the higher the height of the inner bucket, the higher the center of gravity, and the more unstable the rotation. To solve this problem, a balance ring filled with different weight balancing medium can be installed according to the different height of the inner bucket. The structure of the balance ring is the same, only the amount of the balancing medium filled in the balancing cavity is different.

[0049] In summary, the washing machine provided by the present application reduces the number of components that need to be opened, and has good balancing effect.

[0050] The above is the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, these improvements and refinements are also considered to be within the scope of protection of the present application.
