Description

Technical Field

[0001] This invention belongs to the field of washing equipment technology, specifically, it relates to a spray device and washing equipment for washing equipment. Background Technology

[0002] To achieve better rinsing results, modern washing machines are usually equipped with a spray device. During the rinsing stage, the spray device is activated to spray water onto the clothes in the inner drum for rinsing.

[0003] Currently, washing machine spray devices spray at a fixed angle. During the rinsing stage, the rinsing liquid sprayed from the nozzle is sprayed onto the clothes at a preset angle. This spray angle corresponds to a fixed weight of the clothes. However, the number of clothes washed by users is uncertain. Therefore, the spray range of the original spray device is limited, which can easily cause uneven rinsing of clothes in the drum and poor rinsing effect.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a spraying device, including an adjusting component. When the inner drum rotates, the spraying distance of the spray nozzle is continuously changed by continuously adjusting the water pressure flowing through the adjusting component, thereby meeting the rinsing needs of clothes of different weights in the washing machine and improving the rinsing cleanliness ratio of the washing machine.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] A spray device for a washing machine, the washing machine including an inner drum for holding clothes, the spray device comprising:

[0008] The water spray nozzle is positioned facing the inside of the inner cylinder and is used for spraying water.

[0009] The water spray pipe is connected to the water spray nozzle and is used to guide water to the nozzle.

[0010] The water spray pipeline includes a water guide pipe, an inner cylinder shaft, and an adjustment assembly connecting the water guide pipe and the inner cylinder shaft.

[0011] The inner cylinder shaft is connected to the inner cylinder and drives the inner cylinder to rotate. The inner cylinder shaft has a hollow structure with water guiding channels inside.

[0012] An adjusting component is provided, with one end connected to the water guide pipe and the other end integrally rotatably connected to the inner cylinder shaft. The two ends are rotatably and sealed together. The size of the water passage cross section at the two ends of the adjusting component can be changed by rotating the inner cylinder shaft.

[0013] Furthermore, the first end is connected to the water guide pipe and has a first opening for communicating with the inside of the water guide pipe; the second end is integrally rotatably connected to the inner cylinder shaft and has a second opening for communicating with the inside of the inner cylinder shaft; the first end and the second end are rotatably and sealingly connected relative to each other, and the first opening and the second opening are arranged in relative communication, defining the relative position and / or shape of the first opening and the second opening to satisfy the following: when the second end rotates relative to the first end, the overlapping area of ​​the second opening projected onto the first opening changes.

[0014] Furthermore, the first opening is configured to be non-circular and the second opening is configured to be non-circular, and the first opening and the second opening are coaxially arranged.

[0015] Furthermore, the first opening and the second opening are not coaxially arranged.

[0016] Furthermore, the spraying device also includes a first conduit, which is connected to the side wall of the inner cylinder and rotates integrally with the inner cylinder;

[0017] The water spray nozzle is located near the inner cylinder opening on the side wall of the inner cylinder. One end of the first guide tube is connected to the water spray nozzle, and the other end of the first guide tube is connected to the inner cylinder shaft.

[0018] The water flow direction through the spray nozzle is configured to flow sequentially from the water guide pipe, the regulating component, the inner cylinder shaft, and the first guide pipe to the spray nozzle.

[0019] Furthermore, at least two water spray nozzles are provided, and the two water spray nozzles are arranged on the side wall of the inner cylinder along the circumferential direction of the inner cylinder.

[0020] Furthermore, the spraying device also includes a water divider, which is rotatably connected to the inner cylinder. One end of the water divider is connected to the water guide channel of the inner cylinder shaft, and is used to divide the water path through the inner cylinder shaft into at least two branches, and the water flow direction of the two branches extends from the center to the outer periphery.

[0021] Furthermore, the spraying device also includes an outer barrel and a second conduit disposed on the outer barrel. The second conduit is fixedly connected to the outer barrel wall, and one end of the second conduit is connected to the water guide pipe, while the other end of the second conduit is connected to the spray nozzle. The spray nozzle is disposed above the inner barrel. The water flow direction through the spray nozzle is configured to flow sequentially from the inner barrel shaft, the adjusting component, the water guide pipe, and the second conduit to the spray nozzle.

[0022] Furthermore, the inner cylinder is provided with a through hole, which is connected to the water guiding channel of the inner cylinder shaft, allowing water inside the inner cylinder to flow into the water guiding channel of the inner cylinder shaft.

[0023] A second object of the present invention is to provide a washing device, including a spraying device as described above.

[0024] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0025] 1. The spraying device of the present invention has an adjustment component between the spray pipe and the inner cylinder shaft. The adjustment component can adjust the size of the water passage section according to the force of the inner cylinder rotation, thereby adjusting the water flow rate in the spray pipe, so that the spray distance of the spray nozzle can be adjusted, increasing the spray range of the spray nozzle, and making it better for customers.

[0026] 2. The first and second ends of the adjustment component of the present invention are rotatably and sealed together. When they rotate relative to each other, the size of the overlapping cross section of the water passage is adjustable, so that the water flow rate of the flow rate change structure can change accordingly, further ensuring that the spray distance of the spray nozzle is adjustable and increasing the spray range.

[0027] 3. The present invention has at least two spray nozzles, which increases the spray distance of the spray nozzles and ensures the spraying effect.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] The embodiments described below are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the embodiments described below are introduced in conjunction with a pulsator washing machine, the technical solution of the present invention is also applicable to other washing equipment, such as a pulsator-drum dual-power washing machine, a washer-dryer combo, or a shoe washing machine, etc.

[0039] like Figures 1 to 2As shown, the present invention provides a spray device for a washing machine. The washing machine includes an inner drum 10 for holding clothes. The spray device includes a spray nozzle 31, a spray pipe 33, an inner drum shaft 332, and an adjusting assembly 32. The spray nozzle 31 is disposed facing the inside of the inner drum 10 and is used to spray water. The spray pipe 33 is connected to the spray nozzle 31 and is used to guide water to the spray nozzle 31. The spray pipe 33 includes a water guide pipe 331 and an inner drum shaft 332. 32 and an adjusting assembly 32 connecting the water guide pipe 331 and the inner cylinder shaft 332; the inner cylinder shaft 332 is connected to the inner cylinder 10, driving the inner cylinder 10 to rotate, the inner cylinder shaft 332 is set as a hollow structure, and the inside is a water guide channel; one end of the adjusting assembly 32 is connected to the water guide pipe 331, and the other end is integrally rotatably connected to the inner cylinder shaft 332, and the two ends are rotatably sealed to each other, and the size of the water passage cross section at the relative rotation point of the two ends of the adjusting assembly 32 is changed by rotating the inner cylinder shaft 332.

[0040] It is understandable that the water spray pipe 33 connects to the external water source and the water spray nozzle 31. As shown in the figure, the water guide pipe 331 located at the lower part of the water spray pipe 33 is connected to the external water source, the upper part of the water spray pipe 33 is connected to the water spray nozzle 31, and the middle part of the water spray pipe 33 is connected to the adjustment component 32 and the inner cylinder shaft 332 in sequence. That is, the water flows through the water spray pipe 33 to the water spray nozzle 31 and sprays water into the inner cylinder 10.

[0041] Generally, the inner cylinder shaft 332 is located at the bottom of the inner cylinder 10. The axial rotation of the inner cylinder shaft 332 can drive the inner cylinder 10 to rotate synchronously. The inner cylinder shaft 332 is a hollow structure and is connected to the water spray pipe 33. Generally, the outer diameter of the water guide channel of the inner cylinder shaft 332 is preferably equal to the inner diameter of the water guide pipe 331. In addition, the inner cylinder shaft 332 is located above the water guide pipe 331 along the height direction, that is, the water flows upward from the bottom of the inner cylinder 10. Alternatively, the water flow direction can also be downward from the bottom of the inner cylinder 10 into the regulating component 32 and then into the water guide pipe 331, etc. As long as the water flow rate to the spray nozzle 31 can be adjusted, the specific water flow direction is not specifically limited.

[0042] Specifically, in one embodiment, the water nozzle 31 is located near the top of the inner cylinder 10 and is located on the outer side wall of the inner cylinder 10. Generally, the water nozzle 31 is detachably connected to the inner cylinder 10, or the water nozzle 31 is integrally formed with the inner cylinder 10. Preferably, the water nozzle 31 is detachably connected to the inner cylinder 10. Furthermore, the water nozzle 31 is connected to the inner cylinder 10 through a threaded structure, which facilitates assembly, reduces installation difficulty, and also reduces maintenance costs.

[0043] It should be noted that the regulating component 32 can be configured as a water pressure regulating valve, or it can be configured as a structure capable of changing the water flow rate, such as a mechanical seal structure, etc. Furthermore, the regulating component 32 can be located at the bottom end of the inner cylinder shaft 332, extending vertically. That is, one end of the regulating component 32 rotates coaxially with the inner cylinder shaft 332, while the other end remains stationary. This configuration ensures that the water flow cross-section at the point of mutual rotation of the regulating component 32 continuously changes as the inner cylinder 10 rotates, ensuring a change in water flow rate after passing through the regulating component 32. This, in turn, alters the spray distance and spray range of the spray nozzle 31, resulting in better user experience.

[0044] Preferably, the adjusting component 32 includes: a first end 321, connected to the water guide pipe 331, having a first opening 3211 for communicating with the inside of the water guide pipe 331; and a second end 322, integrally rotatably connected to the inner cylinder shaft 332, having a second opening 3221 for communicating with the inside of the inner cylinder shaft 332.

[0045] The first end 321 and the second end 322 are rotatably and sealingly connected to each other, and the first opening 3211 and the second opening 3221 are connected to each other. The relative position and / or shape of the first opening 3211 and the second opening 3221 are defined to satisfy the following: when the second end 322 rotates relative to the first end 321, the area of ​​the overlapping part of the projection of the second opening 3221 onto the first opening 3211 changes.

[0046] It should be noted that the second end 322 can be positioned above the first end 321 and on the same straight line, or the second end 322 can be positioned perpendicular to the first end 321. Preferably, the second end 322 and the first end 321 are on the same straight line. The top of the second end 322 is fixedly connected to the inner cylinder shaft 332 and can rotate synchronously with the inner cylinder shaft 332. The bottom of the second end 322 is rotatably connected to the top of the first end 321. Preferably, the first end 321 and the second end 322 are connected to each other through a mechanical seal structure. In addition, the second end 322 is rotatably connected to the inner cylinder shaft 332. In this way, the water flow in the second end 322 will generate centrifugal force, thereby creating outward pressure on the inner wall. Therefore, the material of the second end 322 is preferably a rigid pipe, such as stainless steel or rigid plastic, to ensure the service life of the second end 322. At the same time, the first end 321 needs to be connected to the tap water pipe, and the first end 321 is kept in a closed position relative to the inner cylinder 10. Therefore, the material of the first end 321 is preferably a flexible pipe, such as a plastic hose, which reduces production costs, is easy to extend and bend, and is easy to place, and can meet the requirements of connecting to water sources in different locations.

[0047] It should also be noted that the first opening 3211 is located at the top of the first end 321, and correspondingly, the second opening 3221 is located at the bottom of the second end 322. That is, the first opening 3211 and the second opening 3221 are arranged opposite to each other. The first opening 3211 can be fixed to the end of the first end 321 by welding, or the first opening 3211 can be fixed to the first end 321 by integral molding. Preferably, the first opening 3211 is integrally molded with the first end 321, and the second opening 3221 is integrally molded with the second end 322. This ensures the stability of the first opening 3211 and the second opening 3221, prevents the first opening 3211 from falling off each other when rotating relative to the second opening 3221, improves the stability of the adjusting component 32, and ensures the spraying effect of the spraying device.

[0048] In this embodiment, the first opening 3211 and the second opening 3221 are arranged opposite to each other. When the first opening 3211 and the second opening 3221 rotate relative to each other, at least part of their cross-sections can overlap. Generally, the size of the overlapping cross-section changes continuously with the rotation of the inner cylinder 10. Specifically, the overlapping cross-section can be changed by changing the relative position of the first opening 3211 and the second opening 3221; or, the flow rate can be changed by changing the shape of the first opening 3211 and the second opening 3221; or, the shape and relative position of the first opening 3211 and the second opening 3221 can be changed simultaneously, etc. As long as the rotation of the inner cylinder shaft 332 can change the flow rate of the water spray pipe 33, the shape and relative position of the first opening 3211 and the second opening 3221 are not specifically limited. Such flexible adjustment and change do not deviate from the principle and scope of the present invention and should be limited to the protection scope of the present invention.

[0049] Preferably, the first opening 3211 is non-circular and the second opening 3221 is non-circular, and the first opening 3211 and the second opening 3221 are coaxially arranged.

[0050] It should be noted that when the first opening 3211 and the second opening 3221 can rotate coaxially, the shapes of the first opening 3211 and the second opening 3221 can be set to different shapes, or the shapes of the first opening 3211 and the second opening 3221 can also be set to different shapes. For example, the first opening 3211 can be set to any one of an ellipse, a rectangle, or an irregular shape, and correspondingly, the second opening 3221 can also be set to any one of an ellipse, a rectangle, or an irregular shape. In this way, when the adjusting component 32 rotates axially and the liquid passes through the flow rate changing structure, the overlapping cross sections correspond to different flow rates, causing the spray distance of the spray nozzle 31 to change back and forth, ensuring the spray range, and thus improving the rinsing effect.

[0051] In another embodiment, a water pressure sensor can be installed on the inner cylinder shaft 332, and a booster can be installed on the spray pipe 33. By detecting the water flow pressure of the inner cylinder shaft 332 in real time, the booster is turned on when the water flow pressure is at its maximum value to increase the water flow pressure in the spray pipe 33. In this way, the liquid sprayed from the spray nozzle 31 by the flow change structure at the maximum water flow pressure can reach the required spray distance, ensuring that the liquid sprayed from the spray nozzle 31 is sufficient to cover the clothes located in the middle of the inner cylinder 10; or, when the water flow pressure is at its minimum value, the booster is turned on to ensure that the spray nozzle 31 can spray normally and prevent the water flow pressure from being too low and causing poor user experience.

[0052] Preferably, the first opening 3211 and the second opening 3221 are not coaxially arranged.

[0053] At this time, the shape of the first opening 3211 and the shape of the second opening 3221 can be the same, that is, the first opening 3211 and the second opening 3221 can both be set as any one of ellipse, rectangle, circle or irregular shape; or, the shape of the first opening 3211 can also be different from the shape of the second opening 3221. For example, the first opening 3211 is set as ellipse and the second opening 3221 is set as rectangle, etc. As long as the first opening 3211 and the second opening 3221 overlap and change shape when they rotate relative to each other, thereby changing the water flow rate of the water outlet of the inner cylinder shaft 332, the shape of the first opening 3211 and the second opening 3221 is not specifically limited.

[0054] Preferably, the cross-sectional shape of the first opening 3211 and the cross-sectional shape of the second opening 3221 are both set to elliptical, and the two ellipses are equal in size and coaxially arranged, which can ensure that the interconnected water flow channels change gradually, avoid sudden changes at the connection point, and thus prevent the interface from tearing. This can meet the spraying requirements, while also improving the service life of the adjustment component 32 and saving maintenance costs.

[0055] Preferably, the spraying device further includes a first conduit 3311, which is connected to the side wall of the inner cylinder 10 and rotates integrally with the inner cylinder 10;

[0056] The water nozzle 31 is located near the top of the inner cylinder 10 on the side wall of the inner cylinder 10. One end of the first conduit 3311 is connected to the water nozzle 31, and the other end of the first conduit 3311 is connected to the inner cylinder shaft 332.

[0057] The water flow direction through the spray nozzle 31 is configured to flow sequentially from the spray pipe 33, the adjustment component 32, the inner cylinder shaft 332 and the first guide tube 3311 to the spray nozzle 31.

[0058] It should be noted that the first conduit 3311 is fixedly connected to the outer wall of the inner cylinder 10, or the first conduit 3311 is detachably connected to the outer wall of the inner cylinder 10. It can be understood that one end of the first conduit 3311 is located at the bottom of the inner cylinder 10, and the other end of the first conduit 3311 is connected to the water spray nozzle 31 at the top of the inner cylinder 10. That is to say, the first conduit 3311 can be set as a straight line, or the first conduit 3311 can also be set as an L-shape. Preferably, the first conduit 3311 is set as an L-shape and fits against the outer wall of the inner cylinder 10. In this way, when the inner cylinder 10 rotates, it can ensure that the first conduit 3311 rotates together with the inner cylinder 10, which further protects the first conduit 3311.

[0059] It is understandable that when the liquid flows in from the water guide pipe 331, it flows sequentially through the inner cylinder shaft 332, the adjusting component 32, the inner cylinder shaft 332 and the first conduit 3311, and finally flows to the spray nozzle 31. Generally speaking, connecting the water guide pipe 331 to the water source can ensure that the water pressure flowing out of the spray nozzle 31 is large enough and changes back and forth, making operation convenient and improving the user experience.

[0060] Preferably, at least two water spray nozzles 31 are provided, and the two water spray nozzles 31 are arranged on the side wall of the inner cylinder 10 along the circumferential direction of the inner cylinder 10.

[0061] Generally, the number of spray nozzles 31 is set to two, or three, or even four, etc., as long as adjacent spray nozzles 31 are evenly spaced on the outer wall of the inner drum 10. Preferably, the number of spray nozzles 31 is set to two. The two spray nozzles 31 can be set on the same plane, or they can be set on different planes. Preferably, the two spray nozzles 31 are set on the same plane. This saves processing time, increases the spray range of the washing equipment during rinsing, thereby ensuring the rinsing rate of the clothes in the inner drum 10 and improving the cleaning ratio of the clothes.

[0062] Furthermore, the two spray nozzles 31 can have the same spray angle, or they can have different spray angles. As long as the spray angle of the spray nozzles 31 meets the rinsing requirements of the washing equipment, the initial spray angle of the spray nozzles 31 is not specifically limited. Preferably, the two spray nozzles 31 are set with equal spray angles.

[0063] Preferably, the sum of the horizontal spray distances of the two water nozzles 31 is not less than the diameter of the inner cylinder 10.

[0064] In this embodiment, the spray distance of each spray nozzle 31 is greater than the radius of the inner drum 10. It can be understood that the spray distance of the spray nozzle 31 is slightly greater than the radius of the inner drum 10, or the spray distance of the spray nozzle 31 can be equal to the diameter of the inner drum 10. Specifically, when the inner drum 10 rotates, the pressure of the water sprayed from the spray nozzle 31 will also change periodically, and the spray distance of the spray nozzle 31 will also change periodically. Generally speaking, the range of change of the spray distance is set to be greater than the radius of the inner drum 10 and less than the diameter of the inner drum 10. Thus, the water sprayed by the spray nozzle 31 can cover the entire inner drum 10, improve the spray range of the spray nozzle 31, ensure that clothes of different weights in the inner drum 10 can be rinsed, ensure the cleanliness ratio of the clothes, and improve the user experience.

[0065] It should be noted that the spray distance of each nozzle 31 is equal to the radius of the inner cylinder 10. In other words, the maximum spray distance of the nozzle 31 is equal to the radius of the inner cylinder 10, at which point the pressure of the nozzle 31 reaches its maximum. During the rinsing process, due to the repeated rotation of the inner cylinder 10, the spray pressure of the nozzle 31 changes repeatedly within the range of maximum and minimum. In this way, the spraying effect can be guaranteed while reducing the spray pressure requirements of the nozzle 31, making it easy to operate.

[0066] Preferably, the spraying device further includes a water divider 35, which is rotatably connected to the inner cylinder 10. One end of the water divider 35 is connected to the water guiding channel of the inner cylinder shaft 332, and is used to divide the water flow through the inner cylinder shaft 332 into at least two branches, and the water flow direction of the two branches extends from the center to the outer periphery.

[0067] It should be noted that the water distribution component 35 is located at the bottom of the inner cylinder 10 and is coaxially arranged with the inner cylinder 10. That is, the water distribution component 35 can rotate synchronously with the inner cylinder 10, and the water distribution component 35 can divide the water flow from the inner cylinder shaft 332 into multiple branches. For example, the bottom of the water distribution component 35 is connected to the top of the inner cylinder shaft 332, and the water flow direction at the top of the inner cylinder shaft 332 is from bottom to top. After passing through the water distribution component 35, the water flow at the top of the inner cylinder shaft 332 can be divided into two first conduits 3311, or the water flow at the top of the inner cylinder shaft 332 can also be divided into three first conduits 3311, or the water flow at the top of the inner cylinder shaft 332 can also be divided into four first conduits 3311, and so on. As long as the water distribution component 35 can adapt the number of branches to the number of spray nozzles 31, the number of branches is not specifically limited.

[0068] For example, the water distributor 35 distributes the water flow from the inner cylinder shaft 332 into two first conduits 3311, and the two first conduits 3311 flow outward from the center. Generally, the water distributor 35 is T-shaped, that is, the lower end of the water distributor 35 is connected to the inner cylinder shaft 332, and the two first conduits 3311 distributed by the water distributor 35 are respectively connected to the corresponding spray nozzles 31. In this way, it is ensured that the water flow in the inner cylinder shaft 332 can flow to the spray nozzles 31 respectively, thereby improving the spray range of the spray nozzles 31.

[0069] It is understood that the water distribution component 35 can divide water flow from one direction into water flow in multiple directions. Specifically, the water distribution component 35 can be configured as a three-way water distribution valve, or it can be configured as a water distribution plate, etc. As long as the water distribution component 35 can distribute the water flow from the inner cylinder shaft 332 into branches with different flow directions, there is no limitation on the specific structure of the water distribution component 35. Preferably, the water distribution component 35 is configured as a three-way water distribution valve, which has a simple structure, is easy to operate, and reduces production costs.

[0070] Preferably, the water flow rate of the first conduit 3311 is equal to the water flow rate of the inner cylinder shaft 332, which can ensure that the spray distance of the corresponding spray nozzles 31 is equal, avoid some clothes not being able to be rinsed due to different water pressure, and thus ensure rinsing efficiency and facilitate production.

[0071] In another embodiment of the present invention, such as Figure 3 As shown, the spraying device also includes an outer barrel 20 and a second conduit 3312 disposed on the outer barrel 20. The second conduit 3312 is fixedly connected to the wall of the outer barrel 20, and one end of the second conduit 3312 is connected to the water guide pipe 331, and the other end of the second conduit 3312 is connected to the water nozzle 31.

[0072] The water spray nozzle 31 is located above the inner cylinder 10;

[0073] The water flow direction through the spray nozzle 31 is configured to flow sequentially from the inner cylinder shaft 332, the adjusting component 32, the water guide pipe 331, and the second guide pipe 3312 to the spray nozzle 31.

[0074] It should be noted that the spray nozzle 31 can be located on the outer lid of the outer tub 20, or it can be located at other positions on the top of the outer tub 20, etc., as long as the spray nozzle 31 remains stationary when the inner tub 10 rotates. Furthermore, the second conduit 3312 connected to the spray nozzle 31 is also fixed to the inner wall of the outer tub 20. Further, the top of the second conduit 3312 is connected to the spray nozzle 31, and the bottom of the second conduit 3312 is connected to the water guide pipe 331. The second conduit 3312 extends from bottom to top along the side wall of the outer tub 20, which avoids interference with other components inside the outer tub 20, while also saving water, reducing energy consumption, and ensuring the normal operation of the spray device.

[0075] Preferably, the inner cylinder 10 is provided with a through hole 36, which is connected to the water guiding channel of the inner cylinder shaft 332, so that the water in the inner cylinder 10 flows into the water guiding channel of the inner cylinder shaft 332.

[0076] It should be noted that the through hole 36 can be located at the axis of the inner cylinder 10 and rotate synchronously with the inner cylinder shaft 332, or the through hole 36 can be located at other positions in the inner cylinder 10. Preferably, the through hole 36 rotates coaxially with the inner cylinder shaft 332. In this way, water at the bottom of the inner cylinder 10 can flow into the water guide channel inside the inner cylinder shaft 332 through gravity and centrifugal force. At this time, the water pressure is low, and the water cannot flow from the second conduit 3312 to the spray nozzle 31. That is, a driving mechanism needs to be provided in the second conduit 3312. For example, the driving mechanism is set as a pump body. Furthermore, the pump body is a fixed-frequency water pump. For example, when the water pressure is too low, it cannot meet the normal spraying requirements of the nozzle 31 onto the inner cylinder 10. Different water flow rates can be pumped to the nozzle 31 through the pump body to achieve repeated changes in the spraying distance of the nozzle 31. Alternatively, if it is necessary to pump water from the bottom of the inner cylinder 10 to the top of the inner cylinder 10, the driving liquid of the pump body can be pumped from the bottom of the inner cylinder 10 to the nozzle 31, etc. In this way, it can be ensured that the water sprayed at the nozzle 31 has a sufficient flow rate, thereby achieving the rinsing of clothes inside the cylinder and providing a better user experience.

[0077] On the other hand, the present invention also provides a washing device. Since the washing device is equipped with the above-mentioned spray device, the washing device has the effect of the spray device, which improves the spray range of the washing device, improves the cleaning ratio of the washing device, and makes it better for users.

[0078] For example, the operating principle of the washing equipment is as follows: When the washing equipment rinses clothes, the motor rotates, and the rigid pipe at the upper end of the spray pipe 33 can rotate coaxially with the motor, while the flexible pipe at the lower end of the spray pipe 33 remains stationary. In this way, the spray pipe 33 can always rotate synchronously with the motor. At the same time, the openings of the first end 321 and the second end 322 are set to be elliptical. Since the cross-sections of the rigid pipe and the flexible pipe are different, but the initial flow rate of water entering the guide pipe 331 is the same, when the rigid pipe rotates axially with the motor, the cross-sectional area of ​​the connection between the first opening 3211 and the second opening 3221 will also change regularly. For example, when the cross-sectional area of ​​the connection between the first opening 3211 and the second opening 3221 is the smallest, the flow rate through the inner drum shaft 332 is the smallest. At this time, the spray distance of the spray nozzle 31 is the largest. When the shapes of the first opening 3211 and the second opening 3221 completely overlap, that is, when the water flow through the connected cross section of the first opening 3211 and the second opening 3221 is at its maximum, the spray distance of the nozzle 31 is at its shortest. In this way, the spray distance of the nozzle 31 can be changed by different flow rates, that is, the spray angle of the nozzle 31 can be changed, avoiding the nozzle 31 spraying at a fixed angle at the same position, increasing the spray range of the nozzle 31, thereby improving the rinsing effect of the washing equipment and providing a better user experience.
