Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of household appliances, and particularly relates to a washing machine. BACKGROUND

[0002] The washing machine is a clothes processing device which converts electric energy into mechanical energy to wash clothes, and has now entered thousands of households and is very popular.

[0003] A spraying structure is arranged on the washing machine product and is applied to the water inlet and the circulating spraying process. At present, the traditional duckbill-shaped nozzle is mostly used on the washing machine product. In the process of water inlet or circulating spraying, the water flow is delivered to the nozzle through the water supply pipeline and then sprayed into the washing chamber of the washing machine. However, the water flow sprayed by the traditional duckbill-shaped nozzle is columnar, and the spraying area is concentrated in a small area, so the spraying and wetting efficiency of the clothes in the washing chamber is low, which also affects the overall washing efficiency of the washing machine. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the purpose of the present disclosure is to provide a washing machine to improve the technical problems of small spraying area of the spraying water flow and low spraying and wetting efficiency in the prior art.

[0005] To achieve at least one of the above purposes, the present disclosure provides the following technical solutions:

[0006] In a first aspect, a washing machine is provided, comprising:

[0007] A cabinet, wherein a drop opening is arranged on the cabinet;

[0008] A drum assembly, wherein the drum assembly is arranged in the interior of the cabinet, and the drum assembly has a washing chamber and a drum opening arranged opposite to the drop opening, and the drum opening is communicated with the washing chamber;

[0009] A door seal ring, wherein the door seal ring is arranged between the drop opening and the drum opening, and the door seal ring is configured to seal the gap between the drop opening and the drum opening;

[0010] A water supply pipeline and a nozzle, wherein the water supply pipeline is arranged in the cabinet, and the water supply pipeline is configured to be connected with a water source and capable of supplying water into the washing chamber through the nozzle;

[0011] The nozzle is arranged on the door seal ring, and the nozzle comprises a nozzle neck, a water outlet nozzle and a guide section connecting the nozzle neck and the water outlet nozzle;

[0012] The nozzle neck is connected with the water supply pipeline;

[0013] The guide section is configured to guide the water flow in the nozzle neck to the water outlet nozzle;

[0014] The water outlet nozzle comprises a water inlet and a water outlet arranged opposite in a first direction, and an inner cavity between the water inlet and the water outlet;

[0015] The water inlet is connected with the guide section;

[0016] The water outlet faces the washing cavity;

[0017] The size of the water outlet in the second direction is greater than the size of the water inlet in the second direction;

[0018] The water outlet has a first edge and a second edge arranged along a third direction, the first edge is provided with a point O, a point A and a point B, and the point O is a midpoint of the first edge;

[0019] A portion of the first edge between the point A and the point B is a line AB, the length of the line AB is greater than 5 mm, and the point O is not on the line AB;

[0020] The distance between the point O and the second edge in the third direction is a first distance, and the distance between any point on the line AB and the second edge in the third direction is greater than the first distance;

[0021] The first direction, the second direction and the third direction are perpendicular to each other.

[0022] In the technical solution, the size of the water outlet in the second direction is greater than the size of the water inlet in the second direction, so as to increase the width of the water flow sprayed from the water outlet, i.e., to increase the coverage width of the sprayed water flow. In addition, the distance between any point on the line AB and the second edge in the third direction is greater than the first distance, i.e., the size of the water outlet in the third direction, and at least one part of the water outlet from the middle to the side in the second direction has an increasing trend. When the water flow is sprayed from the water outlet, the water flow located in the part with the increasing trend has a greater pressure at the middle part of the water outlet than the water flow away from the middle part. The difference in the pressure applied to the water flow generates a pressure difference between different parts of the water flow. The pressure difference forms a "pushing force" on the water flow, which "pushes" the water flow in the middle to the sides under the action of the "pushing force", so as to make the water flow flow and diffuse from the area close to the middle position to the area away from the middle position, i.e., to diffuse to the sides, thereby increasing the flow of the water flow on the sides. By setting the length of the line AB to be greater than 5 mm, the length of the part of the water outlet in the third direction with the increasing trend is large enough, so that the flow from the middle to the side is greater, and the tendency of the sprayed water flow to converge to the middle is smaller, so as to facilitate the diffusion of the water flow from the middle to the side and increase the width of the coverage area of the sprayed water flow. If the length of the line AB is less than 5 mm, the length of the part with the increasing trend will be small, the flow from the middle to the side will be insufficient, and the sprayed water flow will still have a large tendency to converge to the middle, which is difficult to achieve the purpose of increasing the width of the coverage area of the sprayed water flow. By increasing the flow of the water flow on the sides, the influence of the viscous resistance of the water flow and the inner wall of the water outlet can be overcome. After the water flow is sprayed from the water outlet, it disperses to the sides, so that the sprayed water flow forms a large fan-shaped water flow with a larger coverage area, which can more efficiently wet the clothes in the washing cavity and improve the wetting efficiency and washing efficiency of the clothes.

[0023] In some embodiments, a point X and a point Y are provided on the line AB, and the point X is closer to the point O than the point Y.

[0024] The distance between the point X and the second edge in the third direction is a second distance.

[0025] The distance between the point Y and the second edge in the third direction is a third distance.

[0026] The second distance is less than the third distance.

[0027] In the technical solution, the second distance is less than the third distance, that is, for any line AB, any point X and point Y on the line AB that satisfy that point X is closer to point O than point Y, the second distance is less than the third distance; the size of the water outlet in the third direction increases from the middle to both sides along the second direction, so that the water jetted out of the water outlet is subjected to the force pushing from the middle to both sides, the force pushing to both sides applied to the water flow is more uniform, the water flow is better distributed to both sides, the coverage area of the water jet is larger, the wetting efficiency and the washing efficiency of the washing machine are improved, and the uniformity of the distribution of the water jet in the coverage area is also improved, and the spraying effect is better.

[0028] In some embodiments, the water outlet comprises a middle region and two side regions, and the two side regions are disposed on both sides of the middle region along the second direction.

[0029] The middle region protrudes from the side regions in the direction away from the water inlet.

[0030] In the technical solution, the middle part of the water flow in the second direction has a longer travel distance in the travel of the water flow in the inner cavity, the travel distance of the force applied to the middle part of the water flow is increased, and the travel distance of the force applied to the water flow to diffuse to both sides is longer, so that the water flow is better diffused to both sides, and the coverage area of the water jet is more obviously improved.

[0031] In some embodiments, the inner cavity has a first cross section and a second cross section perpendicular to the first direction, and the first cross section is closer to the water inlet than the second cross section.

[0032] The size of the first cross section in the second direction is less than the size of the second cross section in the second direction.

[0033] In the technical solution, the size of the first cross section in the second direction is less than the size of the second cross section in the second direction, that is, the size of the inner cavity in the second direction increases along the direction from the water inlet to the water outlet, and the water flow gradually diffuses to both sides under the restriction of the inner cavity sidewall during the travel of the water flow in the inner cavity, so that the water flow still has a tendency to diffuse to both sides after being jetted out of the water outlet, and the water flow continues to diffuse to both sides after being jetted out, which is beneficial to further improve the coverage area of the water flow jetted out and improve the wetting effect.

[0034] In some embodiments, the area of the first cross section is greater than the area of the second cross section.

[0035] In the technical solution, the water flow in the inner cavity is pressurized by reducing the flow area, so as to overcome the problem that the water flow pressure is reduced due to the increase of the size of the inner cavity in the second direction, improve the pressure of the water flow jetted out of the water outlet, and increase the jetting distance and the coverage area of the water flow.

[0036] In some embodiments, the spray head neck is provided with a first communication opening connected with the water supply pipeline and a second communication opening connected with the guide section;

[0037] At least part of the water flow channel in the spray head neck is formed with a booster section, and the flow area of the booster section decreases in the direction from the first flow communication opening to the second communication opening.

[0038] In the above technical solution, the booster section is arranged to boost the water flow delivered by the water supply pipeline. In the case that the water pressure supplied by the water supply pipeline is low, the water pressure delivered to the guide section and the water outlet nozzle is increased by the boosting effect of the booster section. The water flow sprayed from the water outlet can cover a larger area under the action of greater pressure, thereby improving the wetting and washing efficiency of the washing machine. In addition, the booster section is arranged in the nozzle, which can be directly applied to the existing washing machine when the nozzle is used. Without the need to replace the previous water supply components, such as the circulating pump with greater power, the problem of small coverage area of the sprayed water flow caused by insufficient water supply pressure can be solved, and better applicability is achieved.

[0039] In some embodiments, the guide section is configured to be adjustable in bending degree to adjust the deflection angle of the water outlet relative to the spray head neck.

[0040] In the above technical solution, the bending degree of the guide section is adjustable. When the nozzle is installed on the door seal ring, the relative angle between the spray head neck and the water outlet nozzle can be adjusted according to actual needs. The installation and positioning of the nozzle can be facilitated, so that the water spraying direction is directed to the predetermined area. The orientation of the spray head neck can also be adjusted to be consistent or similar to the extension direction of the water supply pipeline, so as to reduce the stress between the spray head neck and the water supply pipeline in the connected state, and improve the stability and firmness of the connection.

[0041] In some embodiments, a connecting rib is arranged between the nozzle and the door seal ring.

[0042] The connecting rib is configured to limit the position change of the water outlet nozzle relative to the door seal ring.

[0043] In the above technical solution, the connecting rib is arranged to assist in positioning the nozzle, mainly for assisting in fixing the water outlet nozzle. In the process of water spraying, the position change of the water outlet nozzle, such as the sliding distance or deflection angle relative to the door seal ring, is prevented, so as to improve the stability of the position of the nozzle in the water spraying process, i.e. to maintain the stability of the sprayed water flow.

[0044] In some embodiments, the inner cavity has a first cavity wall and a second cavity wall arranged opposite in the third direction.

[0045] The inner cavity is further provided with a reinforcing rib extending in the first direction.

[0046] The reinforcing rib is configured to be connected between the first cavity wall and the second cavity wall to limit the shape change of the water outlet.

[0047] In the technical solution, the reinforcing rib is connected with the first cavity wall and the second cavity wall, so that the pressure of the water flow on the water outlet is overcome to change the shape of the water outlet, the shape of the water outlet is kept stable, the coverage area of the spray water flow is kept stable, and the wetting effect and the washing effect are better.

[0048] In some embodiments, the reinforcing rib is spaced apart from the water outlet by a distance, and the minimum value of the distance is d, which satisfies d≥5mm.

[0049] In the technical solution, after the water flow flows in the inner cavity to the side edge of the reinforcing rib facing the water outlet, the water flow converges from both sides of the reinforcing rib to the middle, thereby avoiding the problem of bifurcation of the water flow sprayed from the water outlet, and improving the uniformity of the water flow distribution in the area and the wetting effect.

[0050] In some embodiments, the reinforcing rib is provided with a third cross section and a fourth cross section perpendicular to the first direction, and the third cross section is farther away from the water outlet than the fourth cross section.

[0051] The size of the third cross section in the second direction is greater than the size of the fourth cross section in the second direction.

[0052] In the technical solution, in the travel corresponding to the position of the reinforcing rib, due to the reduced size of the reinforcing rib, the water flow has a tendency to converge to the middle. After flowing through the reinforcing rib, the water flow converges to the middle at a faster speed based on the original tendency to converge to the middle, and the convergence is more complete, ensuring that the spray water flow can cover the formed planar area in place, and the wetting effect on the clothes in the washing cavity is more uniform, avoiding the situation that some positions are missed or the wetting effect is poor.

[0053] The second aspect also provides a washing machine, comprising:

[0054] A cabinet, the cabinet is provided with a feeding opening;

[0055] A drum assembly, the drum assembly is arranged in the interior of the cabinet, and has a washing cavity and a drum opening arranged opposite to the feeding opening, the drum opening being in communication with the washing cavity;

[0056] A door seal ring, the door seal ring is arranged between the feeding opening and the drum opening, and is configured to seal the gap between the feeding opening and the drum opening;

[0057] A water supply pipeline and a nozzle, the water supply pipeline is arranged in the cabinet, and is configured to be connected with a water source and capable of supplying water into the washing cavity through the nozzle;

[0058] The nozzle is arranged on the door seal, and the nozzle comprises a nozzle neck, a water outlet nozzle, and a guide section connecting the nozzle neck and the water outlet nozzle;

[0059] The nozzle neck is connected with a water supply pipeline;

[0060] The guide section is configured to guide the water flow in the nozzle neck to the water outlet nozzle;

[0061] The water outlet nozzle comprises a water inlet and a water outlet arranged opposite in a first direction, and an inner cavity between the water inlet and the water outlet;

[0062] The water inlet is connected with the guide section;

[0063] The water outlet is directed towards the washing cavity;

[0064] The size of the water outlet in a second direction is greater than the size of the water inlet in the second direction;

[0065] The water outlet is configured to diffuse the water flow via the water outlet towards at least one side of the second direction;

[0066] The first direction is perpendicular to the second direction.

[0067] In the above technical solution, the water flow via the water outlet is diffused towards at least one side of the second direction, so that the water flow flow rate of the side part of the water outlet is increased, and the influence of the viscous resistance of the water flow and the inner wall of the water outlet nozzle can be overcome; after the water flow is sprayed from the water outlet, the water flow is dispersed to at least one side, so that the sprayed water flow forms a large fan-shaped water flow, the coverage area is larger, and the clothes in the washing cavity can be more efficiently wetted, and the wetting efficiency and the washing efficiency of the clothes are improved.

[0102] As part of the creative concept of the present disclosure, before describing the embodiments of the present disclosure, the causes of the problems of small spraying area of the spraying water flow, low spraying and wetting efficiency in the related art are analyzed, and the technical scheme of the embodiments of the present disclosure is obtained through reasonable analysis.

[0103] In related technologies, washing machines are clothing processing devices that convert electrical energy into mechanical energy to wash clothes. They are now widely used in households. Washing machines are equipped with a spray structure for water intake and circulation spraying. Currently, most washing machines use traditional duckbill-shaped nozzles. During water intake or circulation spraying, water is delivered to the nozzles through a water supply pipe and then sprayed into the washing chamber. However, the traditional duckbill-shaped nozzles currently used produce a columnar water stream, concentrating the spray area in a relatively small region. This results in lower efficiency in spraying and wetting the clothes in the washing chamber, which also affects the overall washing efficiency of the washing machine.

[0104] To address this issue, this disclosure provides a washing machine that, by changing the internal structure of the nozzle and the shape of the water outlet, enables the sprayed water flow through the nozzle to form a large fan-shaped water flow, thereby solving the technical problems of small spray area and low spraying and wetting efficiency in the prior art.

[0105] The technical solutions of the embodiments of this disclosure are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0106] Washing machines can be front-loading washing machines, washer-dryer combos, etc. For ease of description, we will use front-loading washing machines as an example for specific explanation below.

[0121] The water outside the washing machine includes municipal water and water stored in an external water storage container, for example, the water source is municipal water pipeline for washing, and the water supply pipeline 4 is directly connected with the municipal pipeline; when the water stored in the external water storage container is used, a water pump is additionally arranged to deliver water to the water supply pipeline 4 through the water pump. The water flow delivered to the water supply pipeline 4 is sprayed into the washing cavity 21 through the nozzle 5 for laundry washing.

[0122] It should be noted that the water supply pipe 4 can also be arranged to communicate with the internal and external water sources through a three-way valve, and during the operation of the washing machine, the three-way valve is adjusted to selectively deliver water from inside or outside the washing machine to the water supply pipe 4. For example, during the water inlet stage, the three-way valve is controlled to communicate the water supply pipe 4 with the external water source to fill water into the washing cavity 21; during the washing stage, the three-way valve is controlled to communicate the water supply pipe 4 with the circulating pump 41 to spray the water in the outer tub and the bottom of the washing cavity 21 to the washing cavity 21 through the water supply pipe 4 and the nozzle 5, thereby realizing the internal water flow circulation spraying.

[0123] In the present embodiment, as shown in Figure 3 and Figure 4 the nozzle 5 is arranged on the door seal ring 3, and the nozzle 5 includes a nozzle neck 51, a water outlet nozzle 52, and a guide section 53 connecting the nozzle neck 51 and the water outlet nozzle 52, the nozzle neck 51 is connected with the water supply pipe 4, and the guide section 53 is configured to guide the water flow in the nozzle neck 51 to the water outlet nozzle 52.

[0124] Optionally, the door seal ring 3 is provided with a mounting hole, and the nozzle 5 is arranged in the mounting hole; wherein the nozzle 5 has multiple different relative positions with respect to the mounting hole, including but not limited to the following modes:

[0125] I. At least part of the nozzle neck 51 is located in the mounting hole, and the guide section 52 and the water outlet nozzle 52 are arranged to extend towards the inner side of the ring body of the door seal ring 3;

[0126] II. The guide section 53 is located in the mounting hole, the nozzle neck 51 extends towards the outer side of the ring body of the door seal ring 3, and the water outlet nozzle 52 extends towards the inner side of the ring body of the door seal ring 3;

[0128] It should be noted that during actual design and installation, the position of the nozzle 5 relative to the door seal ring 3 can be adjusted as needed.

[0129] Optionally, the nozzle neck 51 is a tubular structure, and its cross-sectional shape can be adapted to the water supply pipe 4, and can be circular, oval, rectangular, or other different shapes as needed.

[0130] Optionally, the way in which the spray head neck 51 is connected to the water supply pipe 4 can adopt a direct plug-in mode or a mode of switching through a switching valve structure. In the present embodiment, the direct plug-in mode is taken as an example for description. On the basis of connection through plug-in, a fastening structure can be additionally provided, such as a hoop, a sealant, etc., to ensure that the spray head neck 51 is firmly connected to the water supply pipe 4 and has good sealing performance, so as to prevent problems such as water leakage and disengagement in the subsequent use process.

[0131] Reference is made to Figures 5 to 9 , Figure 5 A cross-sectional view of the nozzle perpendicular to the second direction is provided; wherein the structural composition of the water flow channel formed inside the nozzle is shown. Figure 6 A cross-sectional view of the nozzle perpendicular to the third direction is provided; wherein the variation trend of the size of the inner cavity in the second direction along the direction from the water inlet to the water outlet is shown. Figure 7 A schematic view for determining the first direction is provided. Figure 8 A structural schematic view of the nozzle in the state of facing the water outlet is provided. Wherein the variation trend of the size of the water outlet in the third direction along the second direction is shown. Figure 9 A structural schematic view of the water outlet in the state of facing the nozzle along the third direction is provided. Wherein the positional relationship of the intermediate region and the side region corresponding to the water outlet relative to the water inlet is shown.

[0132] In some embodiments, as shown in Figure 5 and Figure 6 , the water outlet 52 includes oppositely arranged water inlets 521 and water outlets 522, and an inner cavity 523 located between the water inlets 521 and the water outlets 522; wherein the water inlets 521 are connected with the guide section 53 to guide the water flow conveyed by the spray head neck 51 and the guide section 53; the water outlets 522 are arranged towards the inside of the washing cavity 21, and the water flow can be sprayed from the water outlets 522 to the clothes in the washing cavity 21 to wet the clothes.

[0133] Exemplarily, the water outlet is a flat mouth structure. For the sake of convenience, the water outlet is taken as an example of a flat mouth structure for description in this paper.

[0134] In order to facilitate the description of the structure of the nozzle 5, a three-dimensional rectangular coordinate system is arranged on the nozzle 5, and the three coordinate axes are the first direction, the second direction and the third direction; as shown in Figure 5 and Figure 6 , the relative positional relationship between the first direction, the second direction and the third direction and the nozzle 5 is shown.

[0135] Specifically, the first direction refers to the arrangement direction of the water inlets 521 and the water outlets 522, and the first direction, the second direction and the third direction are perpendicular to each other. The arrangement direction of the water inlets 521 and the water outlets 522 can be determined in the following manner:

[0136] I. In the flat mouth-shaped water outlet nozzle 52, the water inlet 521 and the water outlet 522 are both composed of four sides, including two opposite long sides and two opposite short sides. The midpoint of the line connecting the midpoints of the two long sides of the water inlet 521 is P, and the midpoint of the line connecting the midpoints of the two long sides of the water outlet 522 is Q. The direction of the PQ line is the arrangement direction of the water inlet 521 and the water outlet 522, as shown in Figure 7 .

[0137] II. In the flat mouth-shaped water outlet nozzle 52, the first line is a line connecting any two points on the edge of the water inlet 521, and the first line is located in the plane of the water inlet 521. The midpoint of the first line when the length of the first line is the largest is P'. The second line is a line connecting any two points on the edge of the water outlet 522, and the second line is located in the plane of the water outlet 522. The midpoint of the second line when the length of the second line is the largest is Q'. The direction of the P'Q' line is the arrangement direction of the water inlet 521 and the water outlet 522.

[0138] The size of the water outlet 522 in the second direction is greater than the size of the water inlet 521 in the second direction. Increasing the width of the water flow when it is ejected from the water outlet can increase the coverage width of the ejected water flow.

[0139] Further, the inner cavity 523 has a first cross section and a second cross section perpendicular to the first direction, wherein the first cross section is closer to the water inlet 521 than the second cross section, and the size of the first cross section in the second direction is smaller than the size of the second cross section in the second direction. That is, the size of the inner cavity 523 in the second direction increases along the direction from the water inlet 521 to the water outlet 522. It should be noted that the size of the inner cavity 523 in the second direction increases gradually, and in other embodiments, the size can also be increased in steps.

[0140] Wherein, the water flow is transported from the water inlet 521 to the inner cavity 523, and flows to the water outlet 522. During the flow of the water flow in the inner cavity 523, the water flow spreads to both sides as the size of the inner cavity 523 in the second direction increases, so that the size of the water flow in the second direction in the inner cavity 523 increases as the water flow flows. For ease of description, the "size of the water flow in the second direction" is referred to as "width of the water flow" in this paper.

[0141] With the above structure design, the water flow in the inner cavity 523 is ejected from the water outlet 522 into the washing cavity 21. After being ejected from the water outlet 522, the water flow maintains the tendency to spread to both sides during the flow in the inner cavity 523, continues to spread to both sides, and the farther away from the water outlet 522, the greater the width of the water flow, so that the sprayed water flow is in a fan-like shape, which can increase the spraying area.

[0142] AsFigure 8 As shown, the water outlet 522 is configured to diffuse the water flow via the water outlet 522 towards at least one side of the second direction.

[0143] Optionally, the water outlet 522 can be an opening structure that is small in the middle and large on both sides in the second direction.

[0144] Exemplarily, the size of the water outlet 522 in the third direction increases from the middle to both sides along the second direction.

[0145] Specifically, the water outlet 522 has a first edge and a second edge arranged along the third direction, and the first edge is provided with a point O, a point A and a point B, and the point O is the midpoint of the first edge; wherein the distance between the point O and the second edge in the third direction is a first distance; the part of the first edge between the point A and the point B is a line AB, and the point O is not on the line AB, and the distance between any point on the line AB and the second edge in the third direction is greater than the first distance; that is, at least part of the size of the water outlet 522 in the third direction increases from the middle to both sides along the second direction.

[0146] Wherein, the line AB is a part of the first edge, and in actual products, the line AB can be in a straight line shape or in a curved line shape.

[0147] Compared with the scheme in which the line AB is in a straight line shape, when the line AB is in a curved line shape, the flow rate of the flow diverted from the middle part to the side part is also larger, the ability to overcome the tendency of the water flow to converge to the middle is stronger, the water flow diffusion effect is better, and the coverage area is wider.

[0148] Compared with the scheme in which the line AB is in a curved line shape, when the line AB is in a straight line shape, the slope of the part with the increasing trend is certain, the pushing force of the water flow to the side in the second direction is uniform at each position, and the amount of water flow diverted to both sides at each position is also uniform, and the water flow distribution in the coverage area is more uniform.

[0149] Exemplarily, as shown, Figure 8 The first edge is a curved edge CD, the second edge is a curved edge EF, and the first edge, the second edge, and the edges CE and DF together form the water outlet 522; the midpoint O is located on the curved edge CD, the midpoint O bisects the curved edge CD to obtain a curved edge CO and a curved edge DO, and the lengths of the curved edge CO and the curved edge DO are equal. Optionally, the curved edge CD and the curved edge EF are two arcs arranged symmetrically.

[0150] It should be understood that the line AB is located on the curved edge CD, and the line AB is in a curved line shape.

[0151] The dimensions of the water outlet 522 in the third direction increase from the center to both sides along the second direction, at least partially. When water is sprayed from the water outlet 522, the portion of the water outlet 522 with the increasing dimension in the third direction exerts a thrust on the water flow towards both sides, so that the flow rate of the sprayed water away from the center is greater than the flow rate near the center. This overcomes the problem of the water flow converging towards the center after being sprayed, increases the width of the sprayed water flow coverage area, and can more efficiently wet the clothes in the washing chamber during water intake or circulating spraying, thereby improving the efficiency of wetting and washing clothes.

[0152] Generally, for conventionally used nozzle structures, the length of the corresponding first side is about 60mm; in order to ensure that the flow rate of water splitting to the side at the outlet 522 is large enough, the length of the connecting line AB is set to be greater than 5mm.

[0153] By setting the length of the connecting line AB to be greater than 5mm, the length of the part of the outlet 522 that has an increasing trend in the third direction is large enough, the flow rate splitting from the middle to the side is greater, and the tendency of the sprayed water to converge towards the middle is smaller, so as to facilitate the diffusion of the water flow from the middle to the side and increase the width of the sprayed water coverage area.

[0154] If the length of line AB is less than 5mm, the length of the part that tends to increase will be too small, resulting in insufficient flow from the middle to the sides. This will cause the sprayed water to still tend to converge towards the middle, making it difficult to achieve the goal of increasing the width of the sprayed water coverage area.

[0155] Furthermore, points X and Y are defined on line AB, with point X being closer to point O than point Y. The distance between point X and the second side in the third direction is the second distance, and the distance between point Y and the second side in the third direction is the third distance, with the second distance being less than the third distance. That is, for any line AB, for any point X and point Y on line AB where point X is closer to point O than point Y, the second distance is less than the third distance. By using the above structural constraints, the size of the outlet 522 in the third direction can be made to increase from the middle to both sides along the second direction.

[0156] For example, such as Figure 8 As shown, when facing the outlet 522, the outlet 522 is a slit structure that extends left and right along the second direction. The size of the slit is the size of the outlet 522 in the third direction (which can also be understood as the vertical direction of the slit). The size of the slit increases from the middle to the left and right sides along the second direction.

[0157] With the above structural design, the water flow is ejected from the outlet 522. The pressure on the water flow in the middle part of the outlet 522 is greater than that on the two sides. The thrust applied to the water flow to both sides is more uniform, and the effect of water flow diversion and diffusion to both sides is better.

[0158] By increasing the flow rate of the two sides of the water flow, the influence of the viscous resistance of the water flow and the inner wall of the water outlet 52 can be overcome; after the water flow is sprayed out of the water outlet 522, it is dispersed to both sides, so that the sprayed water flow forms a large fan-shaped water flow, covering a larger area; during the water inlet or the circulating spraying process, the clothes in the washing cavity can be more efficiently wetted, and the wetting efficiency and washing efficiency of the clothes are improved. It is also helpful to improve the uniformity of the distribution of the sprayed water flow in the coverage area, and the spraying effect is better.

[0159] Specifically, when the water flow is transported in the pipeline, there is viscous resistance between the water flow and the pipe wall. Under the influence of the viscous resistance, the water flow is more inclined to maintain the integrity after being sprayed out of the pipeline, and is not easy to spread quickly. The water flow will extend forward in a relatively narrow column. In the embodiment, by increasing the flow rate of the two sides of the water flow, the flow rate of the side portion is greater than that of the middle portion in the sprayed water flow, so that the water flow is less likely to converge to the middle. And by setting the shape of the water outlet 522, a "thrust" is applied to the water flow from the middle to the two sides, promoting the spread of the sprayed water flow to the two sides. In this way, the influence of the viscous resistance of the water flow and the pipe wall (the inner wall of the inner cavity 523) is overcome, and the water flow is prevented from converging into a water column again at a distance after being sprayed out, but the water flow can continue to spread after being sprayed out, increasing the spraying coverage area.

[0160] Alternatively, as shown in Figure 8 The edge of the water outlet 522 is arc-shaped, and the size of the water outlet 522 in the third direction gradually increases from the middle to the two sides in the second direction. In this way, when the water flow flows out of the water outlet 522, at any position in the second direction, the water flow will be subjected to pressure to the two sides under the limiting action of the shape of the water outlet 522, so that the water flow tends to spread to the two sides.

[0161] The above structure design applies a more uniform force distribution to the water flow to spread to the two sides, which can improve the spread of the water flow to the two sides to a certain extent, increase the spraying coverage area, and improve the wetting and washing efficiency.

[0162] In another embodiment, the water outlet 522 can also be stepped, divided into multiple regions from the middle to the two sides, and the size of each region of the water outlet 522 in the third direction is constant, and the size of the different regions from the middle to the two sides in the third direction increases.

[0163] It should be noted that the "from the middle to the two sides" defined in the embodiment, the "middle" is not necessarily the middle of the water outlet 522 in the strict sense, but also can be a position that the middle is partially offset to one side. The middle of the water outlet 522 in the strict sense is determined as follows: taking the midpoint of the first edge and the second edge, the midpoint position on the line connecting the two midpoints is the middle of the water outlet 522 in the strict sense; from the middle to the two sides, that is, the position corresponding to the direction of the two sides of the above-mentioned midpoint line.

[0164] And in the embodiment defined by the middle to the two sides, the middle position may be offset to one side, on the one hand due to the error in production and processing; on the other hand, when the specifications of the door seal ring 3 or the nozzle 5 are different, the installation position or the relative angle of the nozzle 5 on the door seal ring 3 is different, and there are other limiting conditions that cannot be replaced or adjusted, and the spray water flow is desired to be sprayed to the set area in the washing cavity 21, the middle position can be adjusted to one side to adjust the coverage area of the spray water flow and the flow at different positions in the coverage area.

[0165] Of course, it should also be noted that the size of the water outlet 522 at different positions in the third direction is different, and the corresponding size change trend extends from the water outlet 522 to the inner cavity 523, so that the water outlet 522 and the side wall of the inner cavity 523 realize smooth transition, so as to avoid the phenomenon that the water flow generates vortex in the inner cavity 523 due to the sudden change of the size of the inner cavity 523 in the transmission process, ensure the smoothness of the water flow in the flow process, reduce the energy loss of the water flow in the nozzle 5, so that the spray distance of the water flow sprayed from the water outlet 522 is farther, which helps to increase the spray coverage area.

[0166] In the embodiment, as shown in Figure 8 and Figure 9 The water outlet 522 includes a middle region 5221 and two side regions 5222, the two side regions 5222 are disposed on the two sides of the middle region 5221 along the second direction, and the middle region 5221 protrudes from the two side regions 5222 in the direction away from the water inlet 521; that is, the middle part of the water outlet 522 is farther away from the water inlet 521 than the two sides.

[0167] By adopting the above structure design, the water flow in the inner cavity 523 flows for a longer distance in the middle part in the second direction. In this way, by setting the shape of the water outlet 522, more pressure is applied to the water flow in the middle part, and the distance of the force applied to the water flow in the middle part is increased. The water flow is better diffused to the two sides, and the coverage area of the spray water flow is improved more obviously.

[0168] Optionally, the middle region 5221 is more convex than the side regions 5222 in the direction away from the water inlet 521, and can be configured in different shapes. In the embodiment, as shown in Figure 9 The middle region 5221 and the two side regions 5222 are configured in arc shapes, and the middle region 5221 and the side regions 5222 are smoothly connected, and the water outlet 522 is in an arc shape with the middle part convex in the direction away from the water inlet 521.

[0169] In other embodiments, the middle region 5221 can be configured in a stepped shape convex to the two side regions 5222, and the middle region 5221 and the two side regions 5222 are at the same position in the first direction in the respective regions.

[0170] In the embodiment, the area of the first cross section is larger than the area of the second cross section, that is, the flow area of the inner cavity 523 decreases in the direction from the water inlet 521 to the water outlet 522, and the water flow in the inner cavity 523 is pressurized by reducing the flow area, so as to increase the distance of the water flow sprayed from the water outlet 522. It should be noted that the flow area of the inner cavity 523 decreases gradually, and in other embodiments, the flow area can be configured to decrease in steps.

[0171] Optionally, as shown in Figure 5 The inner cavity 523 has a first cavity wall 5231 and a second cavity wall 5232 oppositely arranged in the third direction, and the distance between the first cavity wall 5231 and the second cavity wall 5232 in the third direction decreases in the direction from the water inlet 521 to the water outlet 522, so that the flow area of the inner cavity 523 decreases in the first direction.

[0172] The flow area of the inner cavity 523 refers to the area of the cross section of the inner cavity 523 perpendicular to the direction from the water inlet 521 to the water outlet 522.

[0173] In this way, the water flow in the inner cavity 523 is pressurized by reducing the flow area, which overcomes the problem of reduced water flow pressure caused by the increase in the size of the inner cavity 523 in the second direction, improves the pressure of the water flow sprayed from the water outlet 522, and the water flow is sprayed farther and covers a larger area.

[0174] Optionally, the spray head neck 51 is provided with a first communication port connected with the water supply pipeline 4, and a second communication port connected with the guide section 53, at least part of the water flow channel in the spray head neck 51 is formed with a booster section 511, and the flow area of the booster section 511 decreases along the direction from the first communication port to the second communication port. Wherein, the flow area of the booster section 511 refers to the area of the cross section of the booster section 511 perpendicular to the direction from the first communication port to the second communication port; by reducing the flow area, the water flow is boosted. Similarly, the flow area of the booster section 511 decreases can refer to the flow area gradually decreases, or can refer to the flow area decreases in steps.

[0175] With the above structure, the water flow delivered by the water supply pipeline 4 is boosted, in the case that the water pressure supplied in the water supply pipeline 4 is low, the water pressure is increased by the booster section 511, and then delivered to the guide section 53 and the water outlet nozzle 52, and the water flow sprayed from the water outlet 522 can cover a larger area under the action of greater pressure, and the wetting and washing efficiency of the washing machine is improved.

[0176] In addition, the booster section 511 is arranged in the spray nozzle 5, and when the spray nozzle 5 is used, it can be directly applied to the existing washing machine, without the need to replace the previous water supply components, such as the need to replace the circulating pump 41 with greater power, and the problem of small coverage area of the spray water flow caused by insufficient water supply pressure can be alleviated, and the applicability is better.

[0177] Optionally, the booster section 511 can be arranged at different positions in the spray head neck 51, and the positions that can be arranged include but are not limited to the following three kinds: 1, the booster section 511 is located at one end of the spray head neck 51 away from the guide section 53; 2, the booster section 511 is located at one end of the spray head neck 51 close to the guide section 53; 3, the booster section 511 is located at the middle position of the spray head neck 51, and a certain distance is left from the ports at both ends of the spray head neck 51.

[0178] It should be noted that the change of the flow area of the booster section 511 should ensure that the side wall of the water flow channel in the spray head neck 51 is smoothly transitioned between the booster section 511 and the adjacent part outside the booster section 511; and in the case that the booster section 5211 directly connects with the guide section 53, the connection between the booster section 5211 and the guide section 53 also maintains smooth transition. In this way, the sudden change of the flow area in the spray nozzle 5 is avoided to prevent the water flow from generating vortex, the smoothness of the water flow is ensured, the energy loss is reduced, and the coverage area of the spray water flow is increased.

[0179] In addition, the number of the booster section 511 in the spray head neck 51 can be multiple, such as two, three, etc., and multiple booster sections 511 can be arranged at intervals along the flow direction of the water flow.

[0180] In the nozzle 5 structure, on the one hand, the flow area of the inner cavity 523 is arranged to decrease in the water flow direction to pressurize the water flow, and on the other hand, the pressurizing section 511 is arranged to pressurize the water flow, realizing two-stage pressurization or multi-stage pressurization of the water flow, and the pressurization effect is better, and the improvement range of the spraying area is also greater.

[0181] In the embodiment, as shown in the figure, Figure 5 The guide section 53 is used to guide the water flow direction, and in the case of a straight pipe structure, the guide section 53 mainly plays a connecting and conducting role; when the guide section 53 is a curved pipe structure with a certain degree of bending, the water flow will be deflected by a certain angle through the guide section 53, realizing the regulation of the water flow direction.

[0182] For different nozzles 5, the guide section 53 can be arranged to have different degrees of bending to realize the function of deflecting the water flow by different angles, and can be applied to the case that the deflection angle between the water outlet direction of the water outlet 522 and the water flow direction in the nozzle neck 51 is different, so as to select different nozzles 5 according to actual needs.

[0183] Optionally, the guide section 53 is configured to be adjustable in the degree of bending, so as to adjust the deflection angle of the water outlet 522 relative to the nozzle neck 51, that is, to adjust the deflection angle between the water outlet direction of the water flow and the water flow direction in the nozzle neck 51.

[0184] Exemplarily, the specific arrangement of the guide section 53 can adopt the existing universal pipe structure and the corresponding material; wherein the universal pipe is a pipe structure that can be bent in different directions and maintained in the corresponding bent state, which can be made of metal or plastic material, and is commonly used in industrial and household fields, for example, the universal pipe for conveying cooling liquid on a numerical control lathe, which adjusts the degree of bending of the universal pipe so that the liquid outlet direction of the universal pipe is aligned with the machining position for cooling; or the commonly used faucet extension universal pipe in the household, which can conveniently change the flow direction and outlet position of the water flow.

[0185] By adopting the above structure design, the deflection angle of the water outlet 522 relative to the nozzle neck 51 can be changed by adjusting the degree of bending of the guide section 53 of the nozzle 5.

[0186] Wherein, in the state that at least part of the nozzle neck 51 is located in the mounting hole, the nozzle neck 51 and the door seal ring 3 are in a connected and fixed state, and the orientation of the water outlet 522 can be adjusted by adjusting the guide section 53; specifically, when the nozzle 5 is installed on the door seal ring 3, the orientation of the water outlet 522 is adjusted so that the sprayed water flow is sprayed to the set spraying area, and when there is a deviation in the spraying angle after the nozzle 5 is installed, the guide section 53 can be directly adjusted to adjust the water outlet direction, which is simple and convenient to operate.

[0187] In the state that the water outlet nozzle 52 is located in the mounting hole, the water outlet nozzle 52 is in a connected and fixed state with the door seal ring 3; at this time, the bending degree of the guide section 53 is adjusted to adjust the orientation of the shower head neck 51. In this way, the arrangement angle of the shower head neck 51 can be adjusted as needed to better connect with the water supply pipeline 4, so as to avoid the problem that a large stress exists between the shower head neck 51 and the water supply pipeline 4 due to a large inclination angle between the arrangement directions of the shower head neck 51 and the water supply pipeline 4, and to facilitate improving the firmness and stability of the connection between the shower head neck 51 and the water supply pipeline 4.

[0188] Reference is made to Figures 10 to 12 , Figure 10 A schematic view of the connection structure of the nozzle and the door seal ring observed from the inside of the washing machine is provided; the relative position relationship and the connection state of the nozzle and the door seal ring are shown. Figure 11 A schematic view of the connection structure of the nozzle and the door seal ring observed from the inside of the washing machine is provided; the relative position relationship and the connection state of the nozzle and the door seal ring are shown. Figure 10 An enlarged schematic view of part G in FIG. 6 is provided; the structural relationship of the connection of the nozzle and the door seal ring by the connecting rib is shown. Figure 12 A schematic view of the structure of the nozzle is provided; the structural design of the connecting rib provided on the water outlet nozzle is shown.

[0189] In some embodiments, in addition to the manner that the nozzle 5 can be provided as a separate component independent of the door seal ring 3 and mounted on the door seal ring 3, as shown in FIGS. 1 to 5, the nozzle 5 can also be integrally provided on the door seal ring 3 and integrally manufactured with the door seal ring 3, as shown in FIGS. 6 to 8. Figure 10 and Figure 11 The nozzle 5 can be integrally provided on the door seal ring 3 and integrally manufactured with the door seal ring 3.

[0190] Further, in the case that the nozzle 5 is mounted on the door seal ring 3 as a separate component, the nozzle 5 can adopt a hard material commonly used in the structure of the nozzle in the related field, such as metal or plastic, and is provided to pass through the mounting hole on the door seal ring, and another positioning structure can be provided to assist in fixing the nozzle 5 and the door seal ring 3, such as using glue to bond and fix the nozzle 5 and the door seal ring 3, or setting a positioning block on the nozzle 5 and the water supply pipeline 4 to assist in positioning, so as to improve the stability of the nozzle 5 mounted on the door seal ring 3.

[0191] Optionally, the water outlet nozzle 522 is embedded in the door seal ring 3, and in the state that the nozzle 5 passes through the mounting hole, the water outlet nozzle 52 is located in the mounting hole, and the water outlet 522 is flush with the edge of the door seal ring 3 towards the inside of the washing machine. Compared with the scheme that the water outlet nozzle 52 extends to the outside of the mounting hole, the water outlet nozzle 52 is embedded in the door seal ring 3, which can reduce the change of the position of the water outlet nozzle 52 relative to the door seal ring 3 during the water spraying process, and improve the stability of the water spraying direction.

[0192] Here, the position change of the water outlet nozzle 52 relative to the door seal 3 mainly refers to the angular deflection or relative sliding of the water outlet nozzle 52 relative to the door seal 3 under the action of water flow, so that the orientation and spraying position of the water outlet 522 change.

[0193] Further, when the nozzle 5 is integrally formed with the door seal 3, the design of the nozzle 5 is added in the design stage of the door seal 3, and the door seal 3 and the nozzle 5 can be integrally injection molded, without the need to separately set and install the nozzle 5, thereby improving the convenience of use.

[0194] It should be noted that since the door seal 3 is usually made of soft and elastic materials such as rubber to ensure good sealing effect, the nozzle 5 is integrally injection molded with the door seal 3, and during the process of conveying water flow for spraying, the nozzle 5 (especially the water outlet nozzle 52 part) is also prone to position change, that is, the water outlet nozzle 52 has angular deflection, which causes the water flow direction of the spraying water to deviate, affecting the wetting and washing efficiency.

[0195] To this end, as shown in Figure 10 and Figure 11 , a connecting rib 6 is arranged between the nozzle 5 and the door seal 3, and the connecting rib 6 is configured to limit the position change of the water outlet nozzle 52 relative to the door seal 3. The connecting rib 6 is integrally formed with the nozzle 5 and the door seal 3, which can position the nozzle 5 and improve the stability of the position of the nozzle 5 during water spraying.

[0196] Among them, the connecting rib 6 is arranged between the water outlet nozzle 52 and the door seal 3, which can assist in positioning the water outlet nozzle 52; during the process of spraying water flow, the position change of the water outlet nozzle 52 has a more direct effect on the water flow direction of the spraying water; therefore, arranging the connecting rib 6 between the water outlet nozzle 52 and the door seal 3 can better maintain the stability of the water flow direction.

[0197] In addition, as shown in Figure 12 , when the nozzle 5 is arranged as a separate component and installed on the door seal 3, the connecting rib 6 can also be arranged on the nozzle 5 to improve the stability of the water spraying direction of the nozzle 5.

[0198] Alternatively, the connecting rib 6 is fixedly connected to the water outlet nozzle 52, and after the nozzle 5 is installed on the door seal 3, the connecting rib 6 abuts against or is fixedly connected (which can be adhesively connected or locked) to the door seal 3, which can assist in positioning the nozzle 5 and the door seal 3 and improve the stability of the water spraying direction.

[0199] Of course, the connecting rib 6 can also be integrally arranged on the door seal 3, and when the nozzle 5 is installed on the door seal 3, the connecting rib 6 abuts against or is fixedly connected to the water outlet nozzle 52, which can assist in positioning the nozzle 5 and the door seal 3 and improve the stability of the water spraying direction.

[0200] In addition, in order to further improve the stability of the positioning of the nozzle 5, a connecting rib 6 can be arranged on any one or more of the side walls constituting the water outlet nozzle 52, so as to position the water outlet nozzle 52 from different directions and make the water outlet direction of the water outlet nozzle 52 more stable.

[0201] Optionally, the connecting rib 6 is in a plate-shaped structure, and an arc surface is arranged on the side surface of the connecting rib 6 facing the door seal ring 3, which is matched with the corresponding position on the door seal ring 3. In this way, when the connecting rib 6 is abutted or fixedly connected to the door seal ring 3, the contact surface between the connecting rib 6 and the door seal ring 3 is matched with each other, and the positioning effect is more stable.

[0202] Of course, in the case that the connecting rib 6 is fixedly connected to the nozzle 5, a positioning portion can also be arranged on the side of the connecting rib 6 facing the door seal ring 3. The positioning portion is configured to have an area larger than that of the side of the connecting rib 6 facing the door seal ring 3 and an arc surface matched with the corresponding position on the door seal ring 3. When the connecting rib 6 is abutted with the door seal ring 3, compared with the way that the connecting rib 6 is directly abutted with the door seal ring 3 to assist in positioning, the structure design of the above-mentioned positioning portion can increase the area of the connecting rib 6 in contact with the door seal ring 3 and reduce the pressure applied by the connecting rib 6 to the door seal ring 3 during the spraying process. In this way, the abutted part of the door seal ring 3 and the connecting rib 6 is not easy to deform, thereby reducing the risk of change of the water spraying direction of the nozzle 5 and further improving the stability of the water spraying direction of the nozzle 5. When the connecting rib 6 is fixedly connected with the door seal ring 3, the above-mentioned positioning portion can be used as an adhesive component or a locking component, which can increase the contact area between the connecting rib 6 and the door seal ring 3 to ensure the stability of the connection between the connecting rib 6 and the door seal ring 3.

[0203] Reference is made to Figure 13 and Figure 14 , Figure 13 The schematic diagram of the internal structure of the nozzle is provided; and the schematic diagram of the structure relationship in which the first cavity wall 5231 and the second cavity wall 5232 are connected with the reinforcing rib is shown. Figure 14 The sectional view of the nozzle in which the reinforcing rib is arranged is provided; and the position of the reinforcing rib in the inner cavity and the change trend of the size in the second direction are shown.

[0204] As the water flow flows in the water outlet nozzle 52, a pressure is generated on the cavity wall of the inner cavity 523. When the pressure increases to a certain extent, the cavity wall around the inner cavity 523 will be deformed under the action of the pressure, causing the shape of the water outlet 522 to change. The size of the water outlet 522 in the third direction changes under the action of the water flow pressure, especially the size of the middle part of the water outlet 522 increases under the action of the water flow pressure, which can cause the problem that the diffusion range of the spray water flow to both sides is reduced, and the coverage area of the spray water flow is improved at a smaller rate. The above problem is particularly evident when the nozzle 5 and the door seal ring 3 are integrally manufactured. To solve the above problem, the following technical solutions can be used.

[0205] In some embodiments, as shown in Figure 13 and Figure 14 , a reinforcing rib 7 extending in the first direction is arranged in the inner cavity 523 of the water outlet nozzle 52, and the reinforcing rib 7 is configured to be connected between the first cavity wall 5231 and the second cavity wall 5232 to limit the shape change of the water outlet 522.

[0206] With the above structure design, the reinforcing rib 7 is connected with the first cavity wall 5231 and the second cavity wall 5232, which can overcome the pressure of the water flow on the water outlet nozzle 52 to cause the shape change of the water outlet 522, so that the water outlet 522 maintains the above-mentioned state that the size of the water outlet 522 in the third direction increases from the middle to both sides along the second direction, and the coverage area of the spray water flow is kept stable. The wetting effect and the washing effect are better.

[0207] Optionally, the reinforcing rib 7 is located at the middle position of the inner cavity 523 in the second direction. With this structure design, the limitation of the size change of the middle part of the water outlet 522 is stronger, and the effect of preventing the deformation of the water outlet 522 is better.

[0208] Further, a spacing is left between the reinforcing rib 7 and the water outlet 522, and the minimum value of the spacing is d, which satisfies d≥5mm. Exemplarily, the minimum spacing d is the distance between the reinforcing rib 7 and the edge of the water outlet 522 in the first direction. When measuring, first mark a point closest to the water outlet 522 of the reinforcing rib 7 as a near-outlet point, measure the spacing between the near-outlet point and different positions of the water outlet 522, and take the minimum value of the measured multiple data as the minimum value d of the spacing.

[0209] With the above structure design, when the water flow flows to the reinforcing rib 7 in the inner cavity 523, the water flow will flow along the two sides of the reinforcing rib 7 in the second direction. The reinforcing rib 7 can divide the water flow into two parts. Since there is a space between the reinforcing rib 7 and the water outlet 522, the water flow divided into two parts will gradually converge from the two sides of the reinforcing rib 7 to the middle during the flow process. Moreover, by reasonably designing the space between the reinforcing rib 7 and the water outlet 522, the water flow divided into two parts can completely converge before being sprayed from the water outlet 522, so as to avoid the problem of bifurcation of the water flow sprayed from the water outlet 522. That is, the sprayed water flow is in the form of a complete plane, rather than a certain part of the middle without water flow. This is beneficial to improving the uniformity of water flow distribution in the area and better wetting effect.

[0210] In addition, the reinforcing rib 7 is provided with a third cross section and a fourth cross section perpendicular to the first direction. The third cross section is farther away from the water outlet 522 than the fourth cross section. The size of the reinforcing rib 7 in the second direction at the third cross section is greater than the size of the reinforcing rib 7 in the second direction at the fourth cross section. That is, the size of the reinforcing rib 7 in the second direction decreases along the direction from the water inlet 521 to the water outlet 522.

[0211] It should be noted that the size of the reinforcing rib 7 in the second direction decreases along the direction from the water inlet 521 to the water outlet 522 means that the corresponding size gradually decreases. In other embodiments, the corresponding size can also be arranged to decrease in steps.

[0212] In this way, when the water flow flows along the two sides of the reinforcing rib 7 in the second direction, the water flow on both sides of the reinforcing rib 7 has a tendency to converge to the middle due to the decreasing size of the reinforcing rib 7 in the second direction. This can make the water flow converge to the middle faster and more completely, so as to make the sprayed water flow from the water outlet 522 more complete in the form of a plane, ensure that the sprayed water flow can cover a larger area, and make the wetting of the clothes in the washing cavity more uniform, avoiding the situation that some positions are missed or the wetting effect is poor.

[0213] It should be noted that the reinforcing rib 7 can not only be arranged in the inner cavity 523, but also extend from the inner cavity 523 to the guide section 53 and the nozzle neck 51. In this way, the overall structure of the nozzle 5 can be strengthened to reduce the risk of deformation of the nozzle 5 and deviation of the water spraying direction when the water flow impacts the nozzle 5.

[0214] In addition, the number of reinforcing ribs 7 can be multiple, such as two, three, etc. Arranging multiple reinforcing ribs 7 can improve the effect of strengthening the structure of the nozzle 5 and further reduce the risk of deformation of the nozzle 5 (especially the water outlet 522). However, attention should be paid to avoid the problem of too many reinforcing ribs 7 hindering the flow of water.
