Technical Field
[0001] The present invention relates to the technical field of washing machines, and in particular to a water inlet box assembly and a washing machine. Background Art
[0002] Washing machines on the market use water inlet boxes for auxiliary washing. There is a detergent box in the water inlet box for holding detergent. During the washing process, when water enters the siphon cavity of the detergent box to dilute the detergent, when the water level reaches the siphon state, the mixture of detergent and water is discharged through siphon and enters the washing tub. When the external environment of the washing machine changes, such as when the flow of the water inlet valve increases or the user's water pressure is high, the amount of water flowing into the detergent box suddenly increases, causing the water in the siphon cavity of the detergent box to form a local high water level. Because the siphon process is slow, when the water level is high, it will exceed the siphon drainage capacity of the detergent box, and water will overflow from the siphon cavity.

[0055] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.
[0056] Reference Figure 1-Figure 24 , is an embodiment of the water inlet box assembly 200 and the washing machine of the present invention, such as Figure 1-Figure 3 The washing machine includes a housing 100, in which an outer drum and an inner drum are coaxially arranged, the outer drum is used to hold washing water, and the inner drum is used to hold clothes to be washed. A tray 120 is provided at the upper end of the housing 100, and a clothes input port 110 is provided on the tray 120. After the water inlet box assembly 200 is installed on the tray 120, the length direction of the water inlet box assembly 200 is located in the left and right direction of the washing machine, and the width direction is located in the front and back direction of the washing machine. The water inlet box assembly 200 is cantilevered and arranged in the clothes input port 110, and is located outside the tray 120. A step portion 215 is provided at the bottom of the box body 210, and a step matching portion 121 is provided on the tray 120, and the box body 210 is supported on the step matching portion 121 through the step portion 215. The gravity of the water inlet box assembly 200 can be transferred to the tray 120 through the step portion 215 at the bottom of the box body 210, so as to play a supporting role. A fixing part is arranged at the rear side of the box body 210, which is fastened to the disc seat 120 by screws 160. When the water inlet box assembly 200 injects water into the inner cylinder, the outflowing water is directly sprayed into the inner cylinder, which has a larger spraying space; and the outer dimensions of the water inlet box assembly 200 are not limited by the spatial shape of the device cavity of the disc seat 120, which increases the flexibility of the design of the water inlet box assembly 200; and the water inlet box assembly 200 is arranged outside the device cavity of the disc seat, away from the electrical devices, with good water and electricity isolation and high safety.
[0057] like Figure 2-Figure 4 The water inlet box assembly 200 includes a box body 210 having a receiving cavity and a detergent box 230 disposed in the receiving cavity. The detergent box 230 is used to contain detergent, softener, etc. The box body 210 is provided with a water inlet pipe inlet and a water outlet 214, such as Fig.12 As shown, the water outlet 214 is arranged at the bottom of the accommodating cavity. The detergent box 230 is provided with a water inlet 233. One end of the water inlet pipe 140 is connected to the water inlet valve 130 of the washing machine, and the other end is connected to the water inlet 233 on the detergent box 230 through the water inlet pipe inlet. Figure 5 As shown, a sealing gasket 150 is also provided at the inlet of the water inlet pipe on the box body 210. The sealing gasket 150 has a circular through hole and is sleeved with the water inlet pipe 140. The sealing gasket 150 can prevent water from flowing out from the gap at the inlet of the water inlet pipe 140. Figure 7As shown, a siphon chamber 237 is provided in the detergent box 230, and the siphon chamber 237 is connected to the water outlet 214 through a siphon component 2373. The siphon component 2373 includes a siphon tube and a siphon cap. Through the siphon chamber 237, water and detergent can be evenly mixed and then flow out of the water inlet box.
[0058] The water inlet 233 of the detergent box 230 is connected with a water inlet channel and a discharge channel. A part of the water flowing out of the water inlet 233 flows into the siphon cavity 237 through the water inlet channel, and flows into the accommodating cavity of the box body 210 after mixing with the detergent, and flows out from the water outlet 214 to the inner drum of the washing machine; while the other part of the water flows out of the box body 210 through the discharge channel.
[0059] The above-mentioned water inlet box assembly 200 is provided with a leakage channel at the water inlet 233 of the detergent box 230. When water is taken in, a part of the water flows directly out of the box body 210 through the leakage and does not enter the siphon chamber 237, thereby preventing a large amount of water from entering the siphon chamber 237 and exceeding the siphon drainage capacity, causing the water level in the siphon chamber 237 to be too high and overflow, and water and detergent overflow from the box body 210. In addition, the leakage channel has a simple structure and low manufacturing cost.
[0060] In this embodiment, if Figure 6As shown, the box body 210 includes a lower box 211 with an open top, a cover 212 covered on the top of the lower box 211, and a decorative cover 213 is provided on the cover. The decorative cover 213 is hingedly connected to the cover, and the decorative cover 213 can be turned up and down. When the decorative cover is closed, it is covered on the cover 212. The decorative cover 213 includes a decorative cover upper cover 2131 and a decorative cover lower cover 2132. The lower box 211 is provided with a water outlet 214, and at least one input port 2121 is opened on the cover 212, and a maximum input amount limit line is set at the input port 2121. Preferably, two input ports 2121 are provided, namely a detergent input port 2121 and a softener input port 2121. The siphon chamber 237 of the detergent box 230 is provided with two corresponding to the input port 2121, namely a detergent siphon chamber 2371 and a softener siphon chamber 2372. Two water inlets 233 are provided correspondingly, which are connected to the detergent siphon chamber 2371 and the softener siphon chamber 2372 respectively. The box body 210 is roughly in the shape of a rectangular parallelepiped, and the input port 2121 is preferably a circular input port 2121. One side of the detergent box 230 along the length direction is the detergent siphon chamber 2371, and the other side is the softener siphon chamber 2372. Since the amount of detergent required during the laundry process is generally greater than the amount of softener, the volume of the detergent siphon chamber 2371 is set to be larger than the softener siphon chamber 2372, and the detergent siphon chamber 2371 and the softener siphon chamber 2372 are separated by a partition 236. The water inlets 233 of the detergent siphon chamber 2371 and the softener siphon chamber 2372 are both provided with drainage channels. The siphon component 2373 in the detergent siphon chamber 2371 and the softener siphon chamber 2372 is arranged on one side of the input port 2121 to prevent the detergent and softener from being poured directly onto the siphon component 2373 and affecting the solvent mixing and siphon effect.
[0061] In order to fully mix the detergent in the detergent box 230 with the water and dissolve and flush out all the detergent, a water dividing plate 220 is further provided on the upper side of the siphon cavity 237 in the detergent box 230. Figure 6 As shown, a plurality of water leakage holes are arranged on the water dividing plate 220, and the water leakage holes are evenly distributed above the siphon cavity 237. A portion of the water flowing out of the water inlet 233 first flows into the upper side of the water dividing plate 220 through the water inlet channel, and then flows into the siphon cavity 237 through the water leakage holes of the water dividing plate 220. In this embodiment, the water dividing plate 220 includes a first water dividing plate 221 and a second water dividing plate 222, the first water dividing plate 221 is arranged on the upper side of the detergent siphon cavity 2371, and the second water dividing plate 222 is arranged on the upper side of the softener siphon cavity 2372.
[0062] The water inlet 233 is disposed at the rear side of the detergent box 230, and a surrounding wall 235 is disposed on the inner wall of the detergent box 230 at the water inlet 233. Figure 7The surrounding wall 235 includes a side wall and a bottom plate. The surrounding wall 235 and the inner wall of the detergent box 230 surround to form a water inlet cavity. The top opening 2386 of the water inlet cavity forms a water inlet channel, which is connected to the water diversion plate 220. The water inlet 233 is arranged near the upper side of the detergent box 230, and the bottom plate is arranged higher than the detergent box 230, so that the water inlet cavity is located at a high position, which is convenient for water to enter the water diversion plate 220 and ensure the amount of water entering the siphon cavity 237. A discharge channel is arranged at the bottom of the water inlet cavity, which is connected to the accommodating cavity of the box body 210. The water flowing out of the discharge channel flows into the accommodating cavity of the box body 210 below and is discharged from the water outlet 214. The discharged water can be mixed with the siphoned water to further mix the detergent and water evenly and flow out from the water outlet 214 together. In other embodiments, a leakage channel may be provided to be directly connected to the outside of the box body 210, such as by further providing a water outlet hole on the box body 210 for the leakage water to flow out, so that the leakage water does not pass through the box body 210 containing cavity and the water outlet 214, and the leakage water can be discharged from the box body 210 faster.
[0063] Specifically, Figure 8 As shown, a leakage hole 234 is provided at the bottom of the water inlet cavity, that is, on the bottom plate, and the leakage hole 234 is connected with the accommodating cavity and the water outlet 214 of the box body 210 to form a leakage channel. In this embodiment, according to the amount of water to be discharged, two leakage holes 234 are provided at the water inlet 233 in the detergent siphon cavity 2371, which are respectively located on the left and right sides of the water inlet 233. One leakage hole 234 is provided at the water inlet 233 in the softener siphon cavity 2372. The number and size of the leakage holes 234, that is, the amount of leakage, are reasonably set according to the water inlet and water outlet under the premise of ensuring the siphon amount.
[0064] Furthermore, if Figure 7 and Fig. 9 As shown, a drainage chamber 238 is also provided in the detergent box 230. The drainage chamber 238 is arranged adjacent to the siphon chamber 237, and the drainage chamber 238 is used to discharge the water overflowing from the siphon chamber 237 out of the box body 210. When the amount of water inflow is too large, after the drainage channel at the water inlet 233 discharges a part of the water, a large amount of water still enters the siphon chamber 237, making the amount of water in the siphon chamber 237 too large. At this time, through the drainage chamber 238, the water overflowing from the siphon chamber 237 can be discharged from the drainage chamber 238 to the box body 210, so as to prevent the water from overflowing from the top of the box body 210.
[0065] In this embodiment, a retaining rib 239 is provided at the bottom of the detergent box 230, and the retaining rib 239 divides the internal area of the detergent box 230 into a siphon chamber 237 and a discharge chamber 238. The retaining rib 239 and the inner side wall of the detergent box 230 form a discharge chamber 238. An opening 2386 is provided at the bottom of the discharge chamber 238, and the discharge chamber 238 is connected with the accommodating chamber of the box body 210 and the water outlet 214 through the opening 2386. The water flowing out of the discharge chamber 238 flows into the accommodating chamber of the box body 210 below and is discharged from the water outlet 214. The water flowing out of the discharge chamber 238 can be mixed with the water flowing out of the discharge channel and the water siphoned out, so that the detergent and water are further mixed evenly and flow out from the water outlet 214 together. In other embodiments, the drain cavity 238 may be directly connected to the outside of the box body 210 without passing through the containing cavity of the box body 210 and the water outlet 214, so that the overflowing water can be discharged from the box body 210 more quickly.
[0066] Multiple discharge cavities 238 can be provided, and the cavity volume can be different in size. Multiple discharge cavities 238 are formed by providing multiple sections of retaining ribs 239. It can be understood that the height of the retaining ribs 239 is lower than the height of the side wall of the detergent box 230 and the surrounding wall 235 of the water outlet 214. In this embodiment, two discharge cavities are provided in the detergent siphon cavity 2371, namely, a first discharge cavity 2381 and a second discharge cavity 2382. The retaining ribs 239 include a first retaining rib 2391 and a second retaining rib 2392, and both the first retaining rib 2391 and the second retaining rib 2392 are L-shaped retaining ribs 239. The first retaining rib 2391 is provided close to a side wall of the detergent box 230, one end of which is connected to the front side wall of the detergent box 230, and the other end is connected to the surrounding wall 235 at the water inlet 233, and an L-shaped first discharge cavity 2381 is formed between the first retaining rib 2391 and the side wall of the detergent box 230. One end of the second retaining rib 2392 is connected to the other side wall 235 at the water inlet 233, and the other end is connected to the rear side wall of the detergent box 230, forming a rectangular second leakage chamber 2382. The softener siphon chamber 2372 includes three leakage chambers and three sections of retaining ribs. The retaining rib 239 includes a third retaining rib 2393, a fourth retaining rib 2394 and a fifth retaining rib 2395. The third retaining rib 2393 is arranged near the side wall of the detergent box 230, and one end of the third retaining rib 2393 is connected to the front side wall of the detergent box 230, and the other end is connected to the rear side wall of the detergent box 230. A third leakage chamber 2383 is formed between the third retaining rib 2393 and the inner wall of the detergent box 230. One end of the fourth retaining rib 2394 is connected to one side of the surrounding wall 235 at the water inlet 233, and the other end is connected to the middle partition 236, forming a fourth leakage chamber 2384 with the rear side wall of the detergent box 230. The fifth retaining rib 2395 is L-shaped, one end is connected to the other side of the surrounding wall 235 at the water inlet 233, and the other end is connected to the rear side wall of the detergent box 230, forming a fifth leakage chamber 2385. Since the amount of water in the detergent siphon chamber is greater than the amount of water in the softener siphon chamber, a larger leakage chamber is set in the detergent siphon chamber. At the same time, in order to increase the leakage speed of the first leakage chamber 2381 on the side of the detergent siphon chamber, the bottom of the detergent box at the detergent siphon chamber is tilted, and is tilted downward from the outside to the inside, so that the space on one side between the outer bottom surface of the detergent box and the inner bottom surface of the box body is larger, thereby increasing the leakage effect of the first leakage chamber 2381.
[0067] In other embodiments, the number, position and size of the leakage chamber 238 are not specifically limited.
[0068] In this embodiment, the retaining rib 239, the partition 236 and the detergent box 230 are an integrally formed structure. The detergent box 230 includes a detergent box cover 231 and a detergent box body 232. The detergent box cover 231, the detergent box body 232 and the partition 236 are connected by welding to prevent water from overflowing from the upper side.
[0069] In order to further improve the drainage effect, the drainage chamber 238 is located below the water diversion plate 220, and part of the water flowing out of the water leakage hole of the water diversion plate 220 directly flows into the drainage chamber 238, and does not enter the siphon chamber 237, that is, part of the water flowing down the water diversion plate 220 enters the siphon chamber 237, and part of it flows into the drainage chamber 238. Fig.10 The arrows shown in the figure show the direction of water flow. When the amount of water is too large, it can first be discharged through the water diversion plate 220 through the discharge cavity 238. Finally, if the water level in the siphon cavity 237 is still too high and exceeds the retaining rib 239, it will overflow into the discharge cavity 238 for discharge. At this time, the discharge cavity 238 plays a dual role of discharge, ensuring that the water level in the siphon cavity 237 is normal.
[0070] The inner walls of the detergent box 230 are inclined toward the inside of the detergent box 230. The water flowing into the discharge cavity 238 from the water diversion plate 220 can be collected into the lower housing 210 along the inclined inner wall of the detergent box 230. The inclined inner wall of the detergent box 230 can play a role in guiding the overflow water to be collected toward the middle of the housing 210 and flow to the water outlet 214 in the middle of the housing 210. In this embodiment, Fig.12 As shown, the water outlet 214 is in the shape of a strip, and the outflowing water flows out in the shape of a strip that fills the water outlet 214, forming a water flow with the width of the water outlet 214, so that the width of the water flow is large, and the spraying range after being sprayed into the inner drum of the washing machine is large, which increases the contact between the clothes in the washing machine and the spraying water flow, and the spraying water flow forms a flushing effect on the clothes, which is conducive to the removal of dirt on the clothes. In other embodiments, the water outlet 214 can also be a row or multiple rows of water outlet holes.
[0071] like Fig.11 As shown, at least one water retaining rib 216 is provided on the box body 210 at the bottom of the accommodating cavity, and the water siphoned out from the detergent box 230 is guided to the water outlet 214 through the water retaining rib 216. The guiding effect of the water retaining rib 216 can make the water flow to the water outlet 214 faster, and when the siphon water flow is too large, it can play a blocking and guiding role to prevent the water flow from deviating to one side and affecting the water outlet effect of the water outlet 214, so that the flow velocity and flow rate of the strip width of the water outlet 214 are the same or similar, ensuring uniform water outlet.
[0072] When the amount of water is too large and water flows out of the discharge cavity 238, the water retaining rib 216 can also guide the water flowing out of the discharge cavity 238 to prevent the water flow out of the discharge cavity 238 from being too large, causing the water flow to deviate to one side.
[0073] The water retaining ribs 216 are obliquely arranged on the bottom surface of the box body 210, and one end of the water retaining ribs 216 close to the water outlet 214 is arranged close to the center line of the water outlet 214, and the end away from the water outlet 214 is arranged away from the center line of the water outlet 214. That is, starting from the water outlet 214, the water retaining ribs 216 are radially distributed, so that the water flow at the rear side and both sides can be guided and gathered to the middle water outlet 214. In this embodiment, the drainage chamber 238 is arranged on both sides and the rear side of the detergent box 230, and the water retaining ribs 216 can also well guide the drainage water flow at the rear side and both sides to the middle water outlet 214.
[0074] The water outlet 214 is arranged along the length direction of the box body 210 and close to the front side wall of the box body 210. The water retaining rib 216 is arranged at the rear side, and the water retaining rib 216 can better guide the water flow on both sides and the rear side.
[0075] In this embodiment, since the amount of water in the detergent siphon chamber 2371 is relatively large, preferably, four water retaining ribs 216 are provided, including a first water retaining rib 2161, a second water retaining rib 2162, a third water retaining rib 2163 and a fourth water retaining rib 2164. The water retaining rib 216 located below the detergent siphon chamber 2371 and on the outside, that is, the water retaining rib 216 close to the first discharge chamber, is the first water retaining rib 2161, which is in an arc shape, and the front end of the first water retaining rib 2161, that is, the end close to the water outlet 214, is bent outward, that is, slightly bent toward the first discharge chamber. The water retaining rib 216 located below the softener siphon chamber 2372 and on the outside, that is, the water retaining rib 216 close to the third discharge chamber, is the second water retaining rib 2162, which is also in an arc shape, and its end close to the water outlet 214 is bent toward the middle. That is, the bending directions of the first water retaining rib 2161 and the second water retaining rib 2162 are opposite. Such a configuration is because the water flow in the detergent siphon chamber 2371 is large during overflow, and the first water retaining rib 2161 is configured to be an arc to block the water flow, which can more effectively block the water flow from deflecting to one side; while the amount of water in the softener siphon chamber 2372 is small, and no large impact will be generated to deflect the water flow, and the second water retaining rib 2162 is configured to be an arc with opposite bending, which can better guide the water flow into the water outlet 214.
[0076] In this embodiment, a step portion 215 is provided at the bottom of the box body 210 , and a step matching portion 121 is provided on the disc seat 120 . The box body 210 is received on the step matching portion 121 of the disc seat via the step portion 215 .
[0077] Reference Figure 14-24The decorative cover 213 is hinged to the box body 210 and can rotate along the top and rear side of the box body 210. When the cover is flipped up, detergent and softener can be put into the input port 2121 on the box body 210; the decorative cover 213 is flipped down and closed, and is buckled on the box body 210. A first damping structure is arranged between the box body 210 and the decorative cover 213, which is used to increase the friction between the decorative cover 213 and the box body 210 when the decorative cover 213 is opened close to the maximum opening angle. The first damping structure plays a damping role when the decorative cover 213 is flipped up to the maximum angle, which can play a role of reminding the user to prevent excessive force on the decorative cover 213 and damage to the decorative cover 213 and the box body 210; it can slow down the rotation speed of the decorative cover 213 and play a protective role; when the user opens the cover, the damping effect can make the hand feel more comfortable and easy to operate; at the same time, the decorative cover 213 is also stable after opening and is not easy to fall back.
[0078] like Figure 15-21 As shown, the first damping structure includes a first stopper 2124 provided on the box body 210 and a first protrusion 2134 provided on the decorative cover 213. When the decorative cover 213 is axially rotated to a position close to the maximum opening angle, the top of the first protrusion 2134 contacts the top of the first stopper 2124. When the decorative cover 213 continues to rotate to the maximum opening angle, the first protrusion 2134 slides along the top surface of the first stopper 2124. The first protrusion 2134 cooperates with the first stopper 2124, and the structure is simple, no other damping components need to be added, and the cost is low.
[0079] The decorative cover 213 is provided with a rotating shaft 2133, and the box body 210 is provided with a rotating shaft installation groove 2122 and a rotating shaft seat 2123 arranged at both ends of the rotating shaft installation groove 2122. The box body 210 includes a lower box 211 and a cover 212 covered on the lower box 211, and the rotating shaft installation groove 2122 is arranged on the cover 212. Both ends of the rotating shaft 2133 are rotatably arranged on the rotating shaft seat 2123. The first stopper 2124 is arranged in the rotating shaft installation groove 2122. The first protrusion 2134 is correspondingly arranged on the rotating shaft 2133. Preferably, the decorative belt, the rotating shaft 2133, and the first protrusion 2134 are injection molded into an integrally formed structure, and the first stopper 2124 and the rotating shaft installation groove 2122 are injection molded into an integrally formed structure, which has a simple structure and low cost.
[0080] In order to make the decorative cover 213 turn smoothly and produce a uniform damping effect, the top of the first protrusion 2134 is rounded, and the top surface of the first stopper 2124 is a concave arc surface. In another embodiment, the positions of the rotating shaft 2133 and the rotating shaft installation groove 2122 can be interchanged.
[0081] Furthermore, in order to position the maximum opening position of the decorative box, a limiting structure is provided between the box body 210 and the decorative cover 213. When the decorative cover 213 is opened to the maximum opening angle, it abuts against the box body 210 through the limiting structure.
[0082] The limiting structure includes a second protrusion 2135 disposed on the rotating shaft 2133. The second protrusion 2135 and the first protrusion 2134 are located on the same radial plane of the rotating shaft 2133. The second protrusion 2135 is disposed on the rear side of the first protrusion 2134 along the cover opening rotation direction. When the side wall of the second protrusion 2135 abuts against the side wall of the first stopper 2124, the decorative cover 213 opens to the maximum opening angle, that is, the decorative cover 213 opens to the maximum position. In this embodiment, preferably, the maximum opening angle of the decorative cover 213 is 90°, which is convenient for the user to put in the operation, and at the same time, the opening operation space of the decorative cover 213 can be reduced. In other embodiments, the maximum opening angle is not limited to 90°.
[0083] In this embodiment, the first damping structure is provided at two locations, respectively on both sides of the shaft mounting groove 2122. The first damping structure is provided on both sides to ensure that the left and right forces are balanced, the flipping is smooth, the decorative cover 213 is not easily deformed, and the operation is more stable and flexible.
[0084] like Figure 22-24 As shown, a second damping structure is further provided between the box body 210 and the decorative cover 213, and the second damping structure is used to increase the friction between the decorative cover 213 and the box body 210 when the decorative cover 213 is closed and close to the minimum opening angle. In this embodiment, the minimum opening angle is preferably 0°, that is, the decorative cover 213 is completely covered on the top of the box body 210. By providing the second damping structure, when the decorative cover 213 is closed and close to the box body 210, it can play a damping role, produce a damping effect, make the hand feel more comfortable and easy to operate; at the same time, the decorative cover 213 is also stable after closing and is not easy to open, which can prevent the vibration generated by the washing machine during the washing process from causing the decorative cover 213 to shake up and down, and there is no need to add other fixing structures to fix the decorative cover 213 on the box body 210, and the structure is simple.
[0085] The second damping structure specifically includes a third protrusion 2136 disposed on the rotating shaft 2133 and a third stopper 2125 disposed in the groove of the rotating shaft 2133. When the decorative cover 213 axially rotates to a position close to the minimum opening angle, the top end of the third protrusion 2136 contacts the top end of the third stopper 2125. When the decorative cover 213 continues to rotate to the minimum opening angle, the third protrusion 2136 slides along the top end surface of the third stopper 2125.
[0086] In order to make the decorative cover 213 turn over smoothly and produce a uniform damping effect, the top end of the third protrusion 2136 is rounded, and the top end surface of the third stopper 2125 is a concave arc surface.
[0087] The third stopper 2125 is disposed at the middle position of the shaft mounting groove 2122, and the third protrusion 2136 is correspondingly disposed at the middle position of the shaft 2133. In other embodiments, a plurality of second damping structures may be provided.
