Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of household appliances, in particular, relates to a washing machine water inlet box and a washing machine. BACKGROUND

[0002] The washing machine water inlet box is an important component of the washing machine, and the existing washing machine water inlet box cannot uniformly discharge water when the external environment of the washing machine changes, such as when the water inlet valve flow increases, the user water pressure is high, etc., so that the water flowing into the washing machine water inlet box suddenly increases, causing the water outlet of the water inlet box to discharge water unevenly, resulting in a smaller spraying range after spraying into the washing machine inner drum, affecting the water flow to form a water effect on the clothes, and being not conducive to the removal of dirt on the clothes.

[0003] For example, Chinese Patent No. 201510065955.X discloses a washing powder rapid-dissolution water inlet box assembly, which comprises a water inlet box, a powder box, and a water inlet, a water outlet, and a water flow channel on the water inlet box. The water flow adjusting device on the water outlet automatically adjusts the water flow size of the water outlet according to the water pressure in the water flow channel. Specifically, the water flow adjusting device comprises a pipe body, a lower end plate, a spring, a movable baffle, and a drain hole. The pipe body is fixed in the water outlet, and the upper end of the pipe body is flush with or lower than the upper end of the water outlet. The lower end of the pipe body is fixedly provided with a lower end plate. A spring that can be extended up and down is placed on the upper side of the lower end plate. The upper side of the spring is provided with a movable baffle for sealing the inner wall of the pipe body. The movable baffle is in sliding cooperation with the pipe body. A plurality of drain holes are formed on the lower half of the pipe body. When there is no water pressure or the water pressure is low, the movable baffle is located above the uppermost drain hole. When water flow is stored in the water flow channel, the water pressure increases, and the extrusion force of the water pressure on the movable baffle also increases. When the extrusion force is greater than the spring tension, the movable baffle moves downward, the drain hole is exposed, and the water flow flows to the exposed drain hole. The greater the extrusion force, the greater the downward displacement of the movable baffle, and the more the exposed drain holes, and the greater the water flow through the drain holes.

[0004] Although the water flow adjusting device provided by the patent can achieve the effect of uniform water discharge to some extent, the water flow adjusting device involves many parts, and during the water inlet process, the water flow adjusting device cannot adjust in time according to the flow change of the water inlet. The comparative document can only make appropriate adjustments according to the pressure change of the water inlet flow to ensure the uniform discharge of the water outlet when the water flow channel 4 in the water inlet box is full of water.

[0005] Therefore, the present application is proposed. SUMMARY

[0045] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0048] In addition, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is at least two, for example, two, three, etc., unless otherwise explicitly specified and limited.

[0049] As shown in Figures 1 to 5 A water inlet box of a washing machine, comprising: a water box body 10, internally provided with a hollow chamber 11, the water box body 10 being provided with a water inlet 12 and a water outlet 13; a throttling component rotatably arranged in the hollow chamber 11, oppositely arranged with the water inlet 12 and extending to the water outlet 13, for adjusting the opening size of the water outlet 13; the impact force provided by the water inlet 12 drives the throttling component to rotate, so as to adjust the water outlet opening size of the water outlet 13, the greater the water inlet water pressure, the greater the water outlet opening size of the water outlet.

[0050] The existing water inlet box of the washing machine will cause the water flow into the water inlet of the washing machine to suddenly increase, the water outlet of the water inlet box to be uneven, the spraying range after being sprayed into the inner drum of the washing machine to be small, and the water flow to form a water shower effect on the clothes to be affected. Therefore, in the above scheme, the throttling part is arranged opposite to the water inlet 12 and extends to the water outlet 13, the throttling part can rotate in real time according to the water flow of the water inlet 12, and the opening size of the water outlet 13 can be adjusted in real time. When the water flow impact force of the water inlet 12 is large, the throttling part rotates away from the water inlet 12, so that the opening of the water outlet 13 is adjusted to be large, the water outlet area of the water outlet is increased, and then the spraying range of the water flow to the inner drum of the washing machine is increased, and a better water shower effect is formed. In addition, the water inlet box provided in the above scheme is simple in structure and convenient to produce and install. In some embodiments, as shown in Figure 2 the throttling part includes

[0051] The throttling plate 21 is rotatably arranged in the hollow chamber 11, and the throttling plate 21 is provided with a buffer part for bearing the water flow of the water inlet 12 on the side facing the water inlet 12.

[0052] The throttling plate 21 can be rotatably arranged on the bottom wall of the water box body 10 or rotatably arranged on the side wall of the water box body 10. When the throttling plate 21 is arranged opposite to the water inlet 12, the buffer part is arranged on the side of the throttling plate 21 facing the water inlet 12, so that the buffer part faces the direction of the water inlet 12. The water flow flowing from the water inlet 12 can directly flow onto the buffer part of the throttling plate 21, and the water flow can provide more uniform and stable power to the throttling plate 21 after being buffered and stabilized, so that the throttling plate 21 can more stably rotate away from the water inlet 12, thereby achieving a more uniform water outlet effect.

[0053] It should be noted that the throttling plate 21 arranged opposite to the water inlet 12 is not limited to the case that the plane where the throttling plate 21 is arranged is parallel to the side wall where the water inlet 12 is arranged. The throttling plate 21 can also be arranged at an inclination between the plane where the throttling plate 21 is arranged and the side wall where the water inlet 12 is arranged, as long as the water flow of the water inlet 12 can directly impact the throttling plate 21 and the throttling plate 21 can rotate away from the water inlet 12.

[0054] The throttling plate in the above scheme is equivalent to a throttling valve for adjusting the opening of the water outlet, and is used for adjusting the size of the water outlet area of the water outlet. When the water flow impact force of the water inlet is large, the throttling valve can adjust the opening of the water outlet to be large, thereby increasing the water outlet area of the water outlet, and making the water flow uniformly discharged from the water outlet.

[0055] In some embodiments, as shown in Figure 2 andFigure 4 As shown, the buffer portion is a buffer groove 22 recessed from the side of the throttle plate 21 towards the water inlet 12 to the direction away from the water inlet 12.

[0056] The buffer groove 22 recessed from the side of the throttle plate 21 towards the water inlet 12 to the direction away from the water inlet 12 or to the inside of the water box body 10 not only provides a buffer area for the water flow, but also increases the structural strength of the throttle plate 21 at the position towards the water inlet 12, thereby prolonging the service life of the throttle plate 21.

[0057] It can be understood that the buffer groove 22 can be integrally injection molded when the throttle plate 21 is processed.

[0058] In some embodiments, the throttle component further comprises

[0059] A flow guide portion is arranged at the end of the throttle plate 21 extending to the water outlet 13, for guiding the water flow of the water inlet 12 into the water outlet 13.

[0060] In some embodiments, as shown in Figure 2 and Figure 4 The flow guide portion is a protruding block structure 23 protruding from the end face of the end of the throttle plate 21 extending to the water outlet 13 to the direction of the water outlet 13.

[0061] When the water flow of the water inlet 12 flows onto the throttle plate 21, it can be guided along the protruding block structure 23 into the water outlet 13 to achieve the purpose of uniform water outlet.

[0062] It should be noted that the flow guide portion can also be a groove structure capable of guiding the water flow formed at the end of the throttle plate 21 extending to the water outlet 13, as long as it can guide the water flow into the water outlet 13 at the end of the throttle plate 21 extending to the water outlet 13. Therefore, the shape of the flow guide portion is not limited to this.

[0063] In some embodiments, as shown in Figure 3 The water box body 10 is provided with a water inlet 12 and a plurality of water outlets 13, the water inlet 12 is arranged on the first side wall 141 of the water box body 10, and the plurality of water outlets 13 are arranged on the second side wall 142 adjacent to the first side wall 141 of the water box body 10.

[0064] The second side wall 142 extends from the first side wall 141 to the direction away from the water inlet 12, and the plurality of water outlets 13 extend along the extension direction of the second side wall 142.

[0065] The throttle plate 21 is provided with a plurality of protruding structures 23 at one end of the water outlet 13, which are inserted into the water outlet 13 and can move along the extension direction of the water outlet 13.

[0066] By setting the water outlet 13 as a strip structure extending for a certain length, the protruding structures 23 on the throttle plate 21 are arranged in the water outlet 13 of the strip structure. When the water flows into the water inlet 12, the protruding structures 23 will move along the extension direction of the water outlet 13 of the strip structure with the rotation of the throttle plate 21, which can ensure the water flow of the water outlet 13 and make the water flow more uniform. In addition, when the protruding structures 23 move along the extension direction of the water outlet 13, it can also ensure that the open water outlet 13 can all uniformly flow water, avoiding the situation that only part of the water outlet 13 flows water and the water flow is uneven.

[0067] Preferably, the water outlet 13 is in a strip structure, and the width of the strip structure is 2-6mm, preferably 3-4mm.

[0068] In some embodiments, as shown in Figure 2 Also includes

[0069] The limiting component 30 is arranged in the hollow chamber 11 and protrudes from the first side wall 141;

[0070] One end of the throttle component is rotatably arranged on the side of the first side wall 141 away from the water outlet 13, and the other end extends towards the water outlet 13, and the throttle component abuts against the limiting component 30.

[0071] It should be noted that one end of the throttle component can be arranged on the side of the first side wall 141 away from the water outlet 13 and close to the water inlet 12, or on the side of the first side wall 141 away from the water outlet 13 and away from the water inlet 12.

[0072] In some embodiments, as shown in Figure 2 The limiting component 30 includes a connecting plate 31 connected perpendicularly to the first side wall 141;

[0073] A support plate 32 is arranged parallel to the first side wall 141, one end of which is connected to the connecting plate 31, and the other end extends towards the water inlet 12, and the throttle component abuts against the support plate 32.

[0074] By arranging the limiting component 30 on the first side wall 141 where the water inlet 12 is located, the support plate 32 of the limiting component 30 can limit the position of the throttle component on one hand, and on the other hand, it can also reduce the impact force of the water flow on the throttle component, ensuring the stability of the throttle component when rotating.

[0075] Preferably, the connecting plate 31 is arranged at the edge of the first side wall 141 close to the water inlet 12, and the supporting plate 32 is connected with the connecting plate 31 and extends towards the water inlet 12 and partially covers the water inlet 12.

[0076] In some embodiments, as shown in Figure 1 and Figure 2 The hollow region is enclosed by a bottom wall, a plurality of side walls and a sealing cover 15, and a sealing groove 143 is formed on the end face of the plurality of side walls towards the sealing cover 15, as shown in Figure 5 A raised sealing rib 151 is arranged at the edge of the sealing cover 15 corresponding to the sealing groove 143, and the sealing rib 151 of the sealing cover 15 is inserted into the sealing groove 143 during installation.

[0077] In some embodiments, as shown in Figure 2 One end of the throttling component is rotatably arranged on the first side wall 141 away from the water outlet 13 through a rotating shaft 40;

[0078] The rotating shaft 40 is provided with a reset torsional spring 41 for automatically resetting the throttling component to abut against the limiting component 30.

[0079] The throttling plate 21 rotates away from the water inlet 12 around the rotating shaft 40 as the water flow of the water inlet 12 increases, and the greater the water flow, the greater the angle of the throttling plate 21 rotating away from the water inlet 12, so as to ensure uniform water outlet of the washing machine water inlet box 1. When there is no water flow through the water inlet 12, the throttling plate 21 can be reset to contact the limiting component 30 by the action of the reset torsional spring 41.

[0080] It can be understood that the rotation amplitude of the throttling plate 21 can be adjusted by changing the water flow, water flow intensity, water flow speed and other factors of the water inlet 12.

[0081] Preferably, as shown in Figure 2 The second side wall 142 is arranged as an arc structure with the rotating shaft 40 as the center and the throttling plate 21 as the radius.

[0082] In the above scheme, by arranging the second side wall 142 as an arc structure matching the movement track of the end of the throttling plate 21 extending to the water outlet 13, it can be ensured that the protruding block structure 23 can always move along the extension direction of the water outlet 13, thereby ensuring the effectiveness of the throttling component in the washing machine water inlet box 1.

[0083] In some embodiments, the bottom wall of the washing machine water inlet box 1, the sealing cover 15 or the first side wall 141 is provided with a rotating shaft fixing seat 42, one end of the throttle plate 21 is correspondingly provided with a rotating shaft support part 43, and the rotating shaft 40 is rotatably connected with the rotating shaft fixing seat 42 through the rotating shaft support part 43.

[0084] It should be noted that, as shown in Figure 3 The rotating shaft fixing seat 42 can be arranged at a position of the first side wall 141 away from the water outlet 13 and close to the water inlet 12, as shown in Figure 2 The rotating shaft fixing seat 42 can also be arranged at a position of the first side wall 141 away from the water outlet 13 and away from the water inlet 12.

[0085] A washing machine is provided with the washing machine water inlet box 1 as described in any of the above.

[0086] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and any simple modification, equivalent change and modification of the above-mentioned embodiments, which do not depart from the technical solution of the present application, are still within the scope of the present application.
