Detailed Description

Exemplary embodiments that embody features and advantages of the present application are described in detail in the following description. It will be understood that the present application is capable of various modifications in various embodiments, all without departing from the scope of the present application, and that the description and illustrations herein are intended to be by way of illustration only and not to be limiting.

In the description of the present application, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate description of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present application.

In the embodiments shown in the drawings, indications of orientation (such as up, down, left, right, front and rear) are used to explain the structure and movement of the various elements of the present application are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the position of these elements changes, the indication of these directions changes accordingly.

The terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.

In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art in a specific context.

In the related scheme, the inner barrel and outer barrel component of the pulsator washing machine comprises an outer barrel, an inner barrel, a balance ring, an outer barrel cover, a pulsator, a water level sensor for controlling water level and other electrical components. For safety, some washing machines are added with an overflow function so that the water can overflow when the amount of water filled exceeds the maximum amount which can be accommodated, thereby ensuring the safety of users.

In order to improve the washing ratio of laundry, the washing machine is added with a spray washing function, which can be realized by providing a circulation pump, but the manufacturing and using costs of the washing machine are high. If the inner barrel rotates to drive the water flow to rise, when the inner barrel rises to the outer barrel cover, the water flow sprays along the guide groove on the outer cover due to the blocking of the outer barrel cover, so that the washing of clothes is completed, and the manufacturing and using cost of the washing machine can be reduced.

The water flow is driven to rise by the rotation of the inner barrel, so that the cost is reduced by adopting the scheme of realizing the spraying effect, but a large amount of water overflows from the overflow port due to the higher rotation speed of the inner barrel, thereby causing waste and affecting the washing effect.

Referring to fig. 1 and 2, the present application provides a washing machine including a washing machine body, an outer tub 1, an overflow barrier 2, an inner tub, an outer tub cover 3, and a sealing strip.

Referring to fig. 3, the outer tub 1 is fixed to a washing machine body, and an overflow port 11 is formed at an upper portion of a tub wall 12 of the outer tub 1. The outer barrel cover 3 is arranged on the barrel opening of the outer barrel 1 in an openable and closable manner. The inner barrel is rotatably arranged in the outer barrel 1 and can drive water flow to rise to the outer barrel cover 3 to spray from the top when rotating. The overflow baffle 2 is detachably installed in the overflow port 11, so that when spraying, the overflow baffle 2 can prevent water from flowing out of the overflow port 11, thereby avoiding water source waste and ensuring the effect of spraying and washing.

The outer tub 1 may include a tub wall 12 and a water guide plate 13. The water guide plate 13 is fixed to the tub wall 12 such that a drain passage 14 is formed between the water guide plate 13 and the tub wall 12.

The tub wall 12 includes a tub wall body 121 and an outer tub water blocking rib 122.

The tub wall body 121 is provided with a bar-shaped gap in the up-down direction. The edges of the two opposite sides of the strip-shaped notch are turned outwards.

The outer tub water blocking rib 122 has a plate-like structure with an arc-shaped cross section. The two side edges of the outer barrel water retaining rib 122 are respectively sealed and fixed with the two side edges of the barrel wall main body 121 opposite to the strip-shaped notch, so that the outer barrel water retaining rib 122 arches towards the inner part of the outer barrel 1.

The part of the strip-shaped gap remained above the outer barrel water retaining rib 122 is the overflow port 11.

The overflow 11 has a rectangular shape with an open top. The top of the overflow port 11 is flush with the edge of the opening of the outer barrel 1 and is in an open state. That is, the bottom edge of the overflow 11 is formed by the upper edge of the outer tub water blocking rib 122, and both sides of the overflow 11 are formed by both sides of the bar-shaped notch on the tub wall 12. The open top design of the overflow 11 facilitates the insertion of the overflow barrier 2 into the overflow 11 from the open top.

Referring to fig. 4, in some embodiments, the outer tub water barrier 122 may also be an arc-shaped plate structure coinciding with the center of the tub wall 12, that is, the curvature of the outer tub water barrier 122 is the same as the curvature of the tub wall 12. Alternatively, the outer tub water blocking rib 122 and the tub wall body 121 are the tub wall 12 which is originally an integral body, and the overflow port 11 is only a notch formed in the tub wall 12.

The middle portion of the water guide plate 13 bulges away from the tub wall 12, and both sides of the water guide plate 13 are sealed and fixed to the tub wall 12, thereby forming a drain passage 14 between the water guide plate 13 and the tub wall 12.

The water guide plate 13 is positioned outside the outer barrel water guide rib 122, and covers and shields the outer barrel water guide rib 122 and the overflow port 11 from the outer side, so that the overflow port 11 is communicated with a drainage channel 14 formed between the water guide plate 13 and the barrel wall 12, and water overflowed from the overflow port 11 can be drained into a container or a drainage pipe connected with a sewer, and the overflow water is prevented from flowing to the bottom of the washing machine along the outer side of the barrel wall 12 to bring potential safety hazards.

Referring to fig. 5, 6 and 7, the main body of the overflow barrier 2 has an arc-shaped plate structure matched with the water blocking ribs 122 of the outer tub, and the size of the main body is equal to that of the overflow port 11.

The bottom of the overflow baffle 2 is provided with a first clamping groove 21 which can be clamped at the top edge of the outer barrel water retaining rib 122, so that the overflow baffle 2 can be clamped and fixed in the overflow port 11. The top edge of the outer tub water blocking rib 122 may be understood as the edge of the tub wall 12 corresponding to the bottom edge of the overflow 11.

The edge of the barrel wall 12 corresponding to the bottom edge of the overflow port 11 is in sealing clamping connection with the first clamping groove 21 at the bottom of the overflow baffle 2, so that the water is prevented from flowing out from the first clamping groove 21 while the stability is ensured.

Two sides of the overflow baffle 2 are respectively provided with a second clamping groove 22. The two second clamping grooves 22 can be respectively buckled on the edges of the barrel wall 12 corresponding to the two sides of the overflow port 11. Thus, the stability of the fixing of the overflow barrier 2 in the overflow 11 can be further improved.

The edges of the barrel wall 12 corresponding to the two sides of the overflow port 11 and the second clamping grooves 22 on the two sides of the overflow baffle 2 are also in sealing clamping, so that the stability is ensured, and meanwhile, water is prevented from flowing out from the second clamping grooves 22.

The second clamping groove 22 can also play a guiding role when the overflow baffle 2 is installed. Specifically, when the overflow baffle 2 is installed, edges of the tub walls 12 corresponding to two sides of the overflow gap 11 may be inserted into bottoms of the two second clamping grooves 22, and then the overflow baffle 2 is pressed down until the first clamping groove 21 is clamped on the edge of the tub wall 12 corresponding to the bottom of the overflow gap 11, so that the overflow baffle 2 is installed and fixed in the overflow gap 11.

The outside of the overflow barrier 2 (the side facing the water guide plate 13) is provided with a support arm 23 near the two second clamping grooves 22. Therefore, when the overflow baffle 2 receives the pressure of water from inside to outside, the two sides of the overflow baffle 2 can be kept in contact with the barrel wall 12, so that the sealing effect is ensured, and the overflow baffle 2 is prevented from falling off from the overflow port 11.

In particular, when the edges of the corresponding tub walls 12 on both sides of the overflow port 11 are turned outwards and face outwards, the notches of the second clamping grooves 22 on both sides of the overflow baffle 2 which are matched with the edges are faced inwards of the outer tub 1 in the installation state of the overflow baffle 2, and when the overflow baffle 2 receives the pressure of water from inside to outside, the edges of the tub walls 12 are easily separated from the notches of the second clamping grooves 22, so that the overflow baffle 2 loses the blocking effect. After the supporting arm 23 is arranged, the supporting arm 23 can transmit the pressure of water received by the overflow baffle 2 to the water guide plate 13 which is firmly fixed, so that the edge of the barrel wall 12 is prevented from falling out from the notch of the second clamping groove 22, and the overflow baffle 2 is ensured to be sealed and fixed in the overflow port 11.

The supporting arm 23 is also close to the first clamping groove 21 at the bottom of the overflow baffle 2, so that the supporting arm 23 can also play a role in supporting the bottom of the overflow baffle 2, and the sealing fit between the bottom of the overflow baffle 2 and the top edge of the outer barrel water retaining rib 122 is ensured.

The supporting arm 23 may also serve as a guide between the tub wall 12 and the water guide plate 13 during installation of the overflow barrier 2.

In some embodiments, the support arm 23 may be provided in more numbers to enhance the effect of the support, or only one to simplify the structure.

With continued reference to fig. 2 and 8, the outer tub cover 3 includes an upper cover 31 and a lower cover 32, and the upper cover 31 is engaged with the lower cover 32.

When the outer barrel cover 3 is buckled on the outer barrel 1, the lower cover part 32 is in sealing fit with the upper end edge of the barrel wall 12 of the outer barrel 1, the upper end edge of the overflow baffle 2 and the upper end edge of the water guide plate 13.

Referring to fig. 9, a tub cover water blocking rib 321 is provided on an edge of the lower cover part 32. The tub cover water blocking rib 321 surrounds the edge of the lower cover part 32 and protrudes upward. The tub cover water blocking rib 321 is hermetically connected to the edge of the upper cover part 31, thereby forming the overflow path 33 between the upper cover part 31 and the lower cover part 32.

A plurality of first through holes 322 are distributed on the lower cover part 32 near the barrel cover water blocking ribs 321. The first through hole 322 communicates the inner water storage space of the outer tub 1 with the overflow path 33.

The lower cover 32 is in a concave state near the water blocking rib 321 of the barrel cover, and the first through holes 322 are distributed in a concave area, so that water overflowed from the first through holes 322 can flow along the concave area.

Referring to fig. 10, a plurality of water guide ribs 323 are provided on the lower surface of the lower cover portion 32. The areas between the adjacent water guide ribs 323 are in a groove shape converging toward the middle. Therefore, when the inner tub rotates to drive the rising water flow to contact the lower surface of the lower cover 32, the rising water flow can be converged and dropped to the middle along the groove-shaped area between the water guide ribs 323, thereby achieving the spraying effect.

The lower cover portion 32 is provided with a first plate 324 and a second plate 325. The first plate 324 and the second plate 325 form a concave water guide channel. The first through hole 322 is located at the end of the water guiding groove and faces the tangential direction of the circle or any direction avoiding the direction facing downwards or towards the water. So that water is prevented from flowing out of the first through holes 322 during a spraying operation.

The lower cover 32 is further provided with a second through hole 326 corresponding to the area between the water guide plate 13 and the overflow barrier 2. The second through holes 326 communicate the overflow passage 33 and the drain passage 14 surrounded by the water guide plate 13 and the tub wall 12, and water overflowed from the first through holes 322 flows into the drain passage 14 via the overflow passage 33 and the second through holes 326.

The number of the first through holes 322 and the second through holes 326 is not limited, and for example, only one first through hole 322 and one second through hole 326 may be provided to achieve an overflow protection function to some extent.

Referring to fig. 11, the sealing strip 4 is detachably provided between the outer tub cover 3 and the tub mouth of the outer tub 1 and the inlet of the drain passage 14, to prevent water from flowing out between the outer tub cover 3 and the outer tub 1 in the spray mode of operation. In the normal washing mode, the sealing strip 4 can be detached.

In combination with the above structural arrangement, one use and working process of the washing machine of the present application is as follows:

when the spraying function is needed, the outer barrel cover 3 is opened, the overflow baffle plate 2 is sealed and fixed in the overflow port 11, and the sealing strip 4 is arranged on the outer barrel cover 3. After the overflow baffle 2 and the sealing strip 4 are installed, the washing machine can enter a spraying working mode.

In the spraying working mode of the washing machine, when water is injected into the outer barrel 1 and the inner barrel of the washing machine, if a water level sensor of the washing machine breaks down, after the water reaches the use requirement, when the water surface continuously rises to the bottom of the outer barrel cover 3, the continuously injected water overflows from a first through hole 322 at the bottom of the outer barrel cover 3. The overflowed water flows into the drain passage 14 through the overflow passage 33 and the second through hole 326, and thus the overflowed water can be drained to a container or a drain pipe connected to a sewer. And the potential safety hazard caused by the fact that the water quantity which can be contained is exceeded when the water level sensor fails is avoided.

When the inner tub rotates to drive the surrounding water to rise during the spraying operation, the rising water flow can be converged and falls down to the middle along the groove-shaped area between the water guide ribs 323 when contacting the lower surface of the lower cover part 32, so that the clothes and the like in the inner tub are sprayed and cleaned.

When the spraying function is not needed, the ordinary washing mode is restored by disassembling the overflow baffle plate 2 and the sealing strip 4. In the normal washing mode, if the water level sensor breaks down, water injected in an amount exceeding the design maximum flows out from the overflow port 11 and is drained into the container or the drain pipe connected with the sewer through the drain channel 14, so that potential safety hazards are avoided.

While the present application has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration rather than of limitation. As the present application may be embodied in several forms without departing from the spirit or essential attributes thereof, it should be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims.
