Description

Nozzle, impeller washing machine and spraying system and outer barrel cover thereof

Technical Field

The invention belongs to the field of spraying equipment, and particularly provides a nozzle, a pulsator washing machine, a spraying system of the pulsator washing machine and an outer barrel cover of the pulsator washing machine.

Background

The pulsator washing machine mainly comprises a box body, an outer barrel, an inner barrel and a pulsator. Wherein, the outer barrel is fixedly arranged in the box body, the inner barrel is rotatably arranged in the outer barrel, and the wave wheel is rotatably arranged at the bottom of the outer barrel. When the pulsator washing machine performs washing and rinsing operations, the pulsator drives the washing water and the laundry in the outer tub to rotate, so as to achieve the purpose of washing the laundry. When the rotary drum washing machine performs spin-drying operation, the inner barrel drives the clothes in the inner barrel to rotate at high speed, so that the moisture on the clothes is separated from the clothes under the action of centrifugal force.

The pulsator washing machine often has the following problems in the use process: firstly, washing powder and laundry detergent are deposited at the bottom of an outer barrel and are not easily dissolved by washing water; secondly, when the number of the washed clothes is large, the condition that part of the clothes is not soaked by the washing water is easy to occur; thirdly, the down and other clothes often float above the level of the washing water during washing, and the washing effect is poor.

In order to solve the above problems, the conventional pulsator washing machine generally has a spraying device provided on an outer tub cover. For example, patent document No. CN204282066U discloses a pulsator washing machine, in which a plurality of nozzles are provided on an outer tub cover. When the pulsator washing machine works, the circulating water pump can pump the washing water in the outer barrel to the plurality of nozzles, so that the plurality of nozzles spray the washing water onto the clothes in the inner barrel. However, the plate-shaped water baffle on the nozzle has a poor effect of scattering the washing water, and the washing water cannot be uniformly sprayed to the laundry in the inner tub.

Accordingly, there is a need in the art for a new nozzle, a pulsator washing machine, a spray system thereof, and an outer tub cover to solve the above problems.

Disclosure of Invention

Furthermore, the present invention also provides a spraying system of a pulsator washing machine, the pulsator washing machine comprising a cabinet, an outer tub fixedly disposed in the cabinet and an inner tub rotatably disposed in the outer tub, the spraying system comprising a water supply device and a plurality of nozzles according to any one of the above preferred embodiments 5, the plurality of nozzles being respectively disposed on the top of the outer tub, and the one end of the spray channel of each of the nozzles being communicated with the water supply device; when the washing machine works, the water supply device supplies washing water to the plurality of nozzles, and the strip-shaped spray ports of the nozzles enable the washing water to be scattered into the inner barrel.

In the preferable technical scheme of the spraying system, the water supply device is a circulating pump, a water inlet pump port of the circulating pump is communicated with an inner cavity of the outer barrel, and a water outlet pump port of the circulating pump is respectively communicated with the spraying channels of the plurality of nozzles; or the water supply device is a water inlet valve, a water inlet valve port of the water inlet valve is communicated with a water source, and a water outlet valve port of the water inlet valve is respectively communicated with the injection channels of the nozzles; and/or the nozzles are arranged at equal intervals along the circumferential direction of the outer barrel.

In addition, the invention also provides an outer barrel cover of the pulsator washing machine, which comprises a cover body, an annular cavity arranged on the cover body and a plurality of nozzles in the preferred embodiment of the nozzles, wherein one ends of spraying channels of the nozzles are respectively communicated with the annular cavity, and a water inlet communicated with a water source is arranged on the annular cavity.

Further, the invention also provides a pulsator washing machine which is characterized by comprising the spraying system in any one of the preferred embodiments.

As can be understood by those skilled in the art, in a preferred embodiment of the present invention, the spray nozzle body is provided with the spray channel, one end of the spray channel is closed by the water blocking structure, and the side wall of the spray nozzle body is provided with the strip-shaped spray opening communicated with the spray channel, so that when the spray nozzle is supplied with the washing water, the washing water can be sprayed out along the strip-shaped spray opening, and is scattered into a waterfall-like water flow. Therefore, when the nozzle of the present invention is applied to a pulsator washing machine, the nozzle can completely scatter washing water supplied from a circulation pump into an inner tub, uniformly spraying laundry in the inner tub.

Preferably, the bar-shaped jetting port is spirally formed on the sidewall of the nozzle body in a winding manner, and the number of winding turns of the bar-shaped jetting port is half. The washing water sprayed by the nozzle also presents a spiral waterfall shape due to the shape of the strip-shaped spray opening, and when the spiral waterfall falls into the inner barrel, the washing water can spray clothes in the inner barrel three-dimensionally and all-directionally. Therefore, the spray nozzle can improve the spraying effect of the pulsator washing machine on clothes in the inner barrel, and further optimize the washing effect of the pulsator washing machine on the clothes.

It is further preferable that the drain valve 6 is mounted to an inner wall of the cabinet 1, or a person skilled in the art may mount the drain valve 6 to an outer wall of the outer tub 2 as needed. In addition, a person skilled in the art can omit a water pipe between the drain valve 6 and the outer tub 2 as required, so that the drain valve 6 is directly mounted on the outer tub 2 and is communicated with the inner cavity of the outer tub 2.

As shown in fig. 2, a tray 11 is installed on the top of the cabinet 1 of the present invention, and a door 12 is pivotally connected to the tray 11. An outer barrel cover 21 is arranged at the top of the outer barrel 2, and the outer barrel cover 21 is used for shielding the upper edge of the inner barrel 3 and preventing clothes from entering an interlayer between the outer barrel 2 and the inner barrel 3.

As shown in fig. 3 and 4, the outer tub cover 21 mainly includes a cover 211, an annular chamber 212, and a water inlet 213, wherein the annular chamber 212 and the water inlet 213 are both disposed on the cover 211. It will be understood by those skilled in the art that the cover 211 may be an integral structure or may be assembled from multiple separate structures. Illustratively, the cover 211 includes an upper cover and a lower cover, at least one of which is provided with an annular groove. When the upper and lower covers are mounted together, the upper and lower covers enclose the annular channel to form the annular cavity 212.

As shown in fig. 2 and 3, the pulsator washing machine of the present invention further includes a spray system including a circulation pump 8, a circulation water pipe 9, an annular chamber 212, a water inlet 213, and a plurality of nozzles 10.

As shown in fig. 2, the water inlet pump port of the circulating pump 8 is communicated with the inner cavity of the outer tub 2 through a water pipe, and the water outlet pump port of the circulating pump 8 is communicated with the water inlet 213 on the outer tub cover 21 through a circulating water pipe 9. Preferably, a water outlet of the outer tub 2 communicating with the circulation pump 8 is located at the bottom of the outer tub 2. It is further preferable that the circulation pump 8 is mounted to an inner wall of the cabinet 1, or a person skilled in the art may mount the circulation pump 8 to an outer wall of the outer tub 2 as needed. In addition, a person skilled in the art can omit a water pipe between the circulating pump 8 and the outer tub 2 as required, so that the circulating pump 8 is directly mounted on the outer tub 2 and is communicated with the inner cavity of the outer tub 2.

As shown in fig. 3, a plurality of nozzles 10 are fixedly coupled or integrally formed to the cover body 211 at equal intervals in the circumferential direction of the outer tub cover 21, and each nozzle 10 communicates with the annular chamber 212, respectively. Further, the injection port of each nozzle 10 is directed toward the inner tub 3. Further, a person skilled in the art may dispose the plurality of nozzles 10 on the cover 211 at unequal intervals as needed.

As shown in fig. 3 and 5, the inner side of the cover body 211 of the outer tub cover 21 is further provided with an annular shielding structure 2111, and the shielding structure 2111 is used for shielding the nozzle 10 from the user so as to optimize the appearance of the outer tub cover 21.

Although not shown in the drawings, in another possible embodiment of the present invention, a person skilled in the art may fix a plurality of nozzles 10 directly to the top of the outer tub 2 and then make the circulation water pipe 9 communicate with each nozzle 10 directly or via other water pipes, as needed.

As shown in fig. 2, when the circulation pump 8 is operated, the washing water in the outer tub 2 can be sucked out and pumped into the annular cavity 212 of the outer tub cover 21 through the circulation water pipe 9, so that the nozzle 10 sprays the washing water into the inner tub 3 to spray the clothes in the inner tub 3.

In addition, although not shown in the drawings, in another possible embodiment of the spraying system of the present invention, a person skilled in the art may also connect the water inlet 213 of the outer tub cover 21 with the water inlet valve of the pulsator washing machine through a water pipe as needed. When the inlet valve port of the inlet valve is connected to the water tap, the tap water can be supplied to the annular chamber 212 along the path of the inlet valve, the water pipe and the inlet 213, thereby allowing the nozzle 10 to spray the tap water onto the laundry in the inner tub 3 to wet the laundry.

Further, one skilled in the art can also use the spraying system of the present invention to have the above-mentioned circulation pump 8, circulation water pipe 9, water inlet valve and water pipe connecting the water inlet valve and the water inlet 213, and connect a stop valve in series between the water inlet valve and the water inlet 213, as required. At this time, the circulation pump 8 and the water inlet valve may be separately or collectively used as water supply means. When the tap water is required to spray the laundry, the water inlet valve and the shutoff valve are opened. The circulation pump 8 is operated when it is required that the washing water in the outer tub 2 is sprayed to the laundry.

The nozzle 10 of the present invention will be described in detail with reference to fig. 6 to 11.

As shown in fig. 6 and 7, the nozzle 10 of the present invention includes a nozzle body 101 and a water guard structure 102. The nozzle body 101 and the water stop structure 102 may be secured together by any suitable connection, such as welding, fusing, bonding, etc. Alternatively, the nozzle body 101 and the water blocking structure 102 may be integrally formed as needed by those skilled in the art.

As shown in fig. 6, 7 and 11, the nozzle body 101 is provided with a spray passage 1011 in the axial direction, and a nozzle body 101 is provided with a linear spray opening 1012 on a side wall thereof. The water blocking structure 102 is provided at one end of the nozzle body 101 (the upper end of the nozzle body 101 as shown in fig. 11), and the water blocking structure 102 closes one end of the injection passage 1011. The lower end of the spray channel 1011 in figure 11 communicates with the annular chamber 212 when the nozzle 10 is mounted to the outer tub cover 21. The washing water in the annular chamber 212 is sprayed from the bar-shaped spray ports 1012 after passing through the spray passage 1011 and falls into the inner tub 3. Those skilled in the art will appreciate that the nozzle body 101 may be any feasible shape, such as a circular string configuration, a square string configuration, a tapered string configuration, and the like.

Although not shown in the drawings, in a preferred embodiment of the present invention, the spraying direction in which the stripe-shaped ejection openings 1012 are opened (i.e., the outward extending direction of both side walls of the stripe-shaped ejection openings 1012) is biased toward one side of the water guard structure 102. So that the washing water sprayed from the strip-shaped spraying openings 1012 can be deviated to one side of the water blocking structure 102 as shown in fig. 12, and most of the washing water can directly fall to the position of the inner tub 3 close to the axis, thereby effectively spraying the clothes in the inner tub 3.

Further, those skilled in the art may also make the outward extending direction of the two side walls of the linear ejection orifice 1012 perpendicular to the radial direction of the nozzle body 1011, as necessary.

As shown in fig. 6, 8 to 10, the linear ejection port 1012 is spirally wound and formed on the side wall of the nozzle body 101, and the number of windings of the linear ejection port 1012 is half a turn. So that the washing water sprayed from the strip-shaped spray ports 1012 can be sprayed in a semicircular fan shape as shown in fig. 13, the spraying range of the washing water is enlarged, and the spraying effect of the pulsator washing machine is optimized.

In conjunction with the spray effect diagrams of the nozzles 10 shown in fig. 12 and 13, it can be understood by those skilled in the art that the washing water sprayed from the bar-shaped spray ports 1012 is a spiral waterfall-shaped water flow.

In addition, the person skilled in the art can also spray the washing water sprayed from the bar-shaped spraying openings 1012 in a fan shape smaller than a semicircle as shown in fig. 14 by winding less than half of the circle as required.

Further, a person skilled in the art may also provide a plurality of the stripe-shaped ejection openings 1012 on the nozzle body 101 as necessary. Preferably, the plurality of stripe-shaped ejection openings 1012 are arranged in parallel.

Although shown and described, in another possible embodiment of the present invention, one skilled in the art can extend the strip-shaped injection port 1012 to the water guard structure 102, and optionally dispose the water guard structure 102 in a convex structure to the side away from the nozzle body 101, such as disposing the water guard structure 102 in an inverted bowl-shaped structure or a cone-shaped structure, as required.

Further, in other possible embodiments of the present invention, a person skilled in the art may form the linear ejection opening 1012 on the nozzle body 101 in a non-spiral winding manner as needed, for example, the linear ejection opening 1012 is provided in a V shape, an M shape, an N shape, a Y shape, or the like. Alternatively, it is also possible for those skilled in the art to set the strip ejection openings 1012 in an I-shape and set the strip ejection openings 1012 along the axial direction of the nozzle body 101 as necessary. Alternatively, the stripe-shaped ejection openings 1012 may be set to any other feasible ejection openings as desired by those skilled in the art. For example, the ejection port is provided in a plurality of hole structures arranged in sequence. Preferably the plurality of hole structures are equally spaced. As will be appreciated by those skilled in the art, the aperture configuration is a circular aperture, a rectangular aperture, a square aperture, a quincunx aperture, or the like.

It should be noted that, in the preferred embodiment of the present invention, the stripe-shaped spraying opening 1012 is a long and narrow slit, and the width of the slit can be adjusted by those skilled in the art according to actual needs.

Based on the above description of the present invention, it can be understood by those skilled in the art that the spiral strip-shaped jet orifice 1012 is provided on the nozzle body 101 of the nozzle 10, so that the nozzle 10 can jet spiral waterfall-shaped water flow, which can form a height difference in the circumferential direction and the radial direction of the inner tub 3, and further, the clothes in the inner tub 3 can be sprayed three-dimensionally and omni-directionally, and the washing effect of the washing machine is preferable.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
