Description

Technical Field

[0001] This invention pertains to a laundry washing device in the field of household appliance technology, specifically, it relates to a water inlet box structure for a washing machine. Background Technology

[0002] As consumers' pursuit of a higher quality of life increases, washing machines have become indispensable in people's lives. The water inlet box, an important component of the washing machine, is typically made of plastic. Inside the water inlet box is a pull-out dispensing tray containing detergent, liquid detergent, disinfectant, fabric softener, and other additives. A water outlet at the bottom of the water inlet box allows the incoming water to flush these additives into the washing machine drum, thus washing and wetting the load inside.

[0003] However, because the water pressure of the washing machine's water supply source may be too high or unstable, the water flow from the outlet may be too rapid, which may cause excessive water pressure in the water inlet box and large fluctuations in the flow rate of the water flowing from the outlet of the inlet box. This not only affects the water pattern but may even cause the water inlet box to overflow and leak.

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

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a water injection box for a washing machine. The present invention aims to solve the problem that the water injection box in the prior art cannot adjust the water injection pressure, thereby achieving the purpose of automatically adjusting the water pressure of the water injection box of the washing machine and maintaining the water shape.

[0006] To solve the above-mentioned technical problems and achieve the above-mentioned objectives, the technical solution adopted in this application is as follows:

[0007] This invention discloses a water inlet box for a washing machine. The water inlet box body is cylindrical, and the internal hollow cavity is divided into a central water inlet cavity and an outer peripheral water outlet cavity. The outer peripheral water outlet cavity is divided into a first water outlet cavity and a second water outlet cavity. The first water outlet cavity is connected to the central water inlet cavity and the second water outlet cavity through openings that are arranged opposite to each other in the circumferential direction of the body.

[0008] Furthermore, the water injection box body is provided with a first water outlet connected to the first water outlet chamber and a second water outlet connected to the second water outlet chamber. The first water outlet chamber and the second water outlet chamber are connected through a second opening. The second opening and the first water outlet are located on opposite sides of the first water outlet chamber in the circumferential direction of the columnar body, and the second opening and the second water outlet are located on opposite sides of the second water outlet chamber in the circumferential direction of the columnar body.

[0009] Furthermore, the water injection box body is provided with a water inlet that is connected to the central water inlet cavity. The central water inlet cavity is connected to the first water outlet cavity through the first opening. The second opening and the first water outlet cavity are located on the same side of the first water outlet cavity in the circumferential direction of the columnar body.

[0010] Furthermore, the main body has an annular rib inside, the inner side of the annular rib forms a central water inlet cavity, and the space between the outer side of the annular rib and the inner side of the main body forms a peripheral water outlet cavity. The annular rib has a first opening that connects the central water inlet cavity and the peripheral water outlet cavity. The peripheral water outlet cavity has two baffles extending in different radial directions from one end of the columnar main body to the other end. The two baffles divide the peripheral water outlet cavity into a first water outlet cavity and a second water outlet cavity. The side walls of the columnar main body on both sides of the first baffle are respectively provided with a first water outlet and a second water outlet. The first opening and the first water outlet are both located on the same side of the first baffle. The second baffle has a second opening that connects the first water outlet cavity and the second water outlet cavity on both sides.

[0011] Furthermore, one end of the columnar body is a detachable end cap, and a connector is provided at the center of the end cap, which extends coaxially into the central water inlet cavity. The internal channel of the connector forms a water inlet, and the outer wall of the part of the connector that extends into the central water inlet cavity is in sealed contact with the inner wall of the annular rib. The first opening is located at one end of the annular rib and on the same side as the end cap. At least a part of the first opening is staggered with the connector to connect the central water inlet cavity and the first water outlet cavity.

[0012] Furthermore, there is a gap between the end of the second baffle and the end cap, and the gap forms a second opening that connects the first water outlet cavity and the second water outlet cavity; the second opening is on the same side as the end cap.

[0013] Furthermore, a row of water outlets is provided at different radial positions on the sidewall of the columnar body. The first row of water outlets includes multiple first water outlets spaced apart along the axial direction, and the second row of water outlets includes multiple second water outlets spaced apart along the axial direction. Preferably, the first row of water outlets and the second row of water outlets are arranged side by side or staggered, one-to-one.

[0014] Furthermore, each of the first outlets in the first column is a straight hole with an opening axis set radially along the columnar body; at least some of the second outlets in the second column are oblique holes with an opening axis set inclined radially along the columnar body; preferably, the second outlets have an increasing angle of inclination of the opening axis from the middle of the columnar body to both ends, and the inclination direction on both sides is inclined outward to the corresponding side, so as to expand the coverage area of ​​the water flow.

[0015] Furthermore, the outer end of the outlet is provided with guide ribs that protrude outward from the outer wall of the columnar body and are arranged in a ring along the outlet opening.

[0016] The present invention also provides a washing machine, including any of the washing machine water inlet boxes described above.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0018] By sequentially connecting the central water inlet chamber and two water outlet chambers through openings, and positioning these two openings opposite each other in the circumferential direction of the cylindrical water injection box, the first water outlet chamber acts as a buffer to cushion the water flow. This allows lower-pressure water to flow into the washing machine through the outlet in the first water outlet chamber, while higher-pressure water flows through the outlets in both the first and second water outlet chambers. This represents a significant technological advancement in regulating and diverting the water flow through the two sequentially connected water outlet chambers. Furthermore, because the two openings are located at opposite ends of the first water outlet chamber, the water flow can fully utilize the circumferential extension of the first water outlet chamber, increasing the flow channel length and enhancing the water injection box's effectiveness in regulating and stabilizing the water flow.

[0019] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The present invention will be further described in detail below with reference to the embodiments.

[0037] like Figures 1 to 8 As shown, an embodiment of the present invention provides a water injection box for a washing machine. The water injection box body 1 is cylindrical, and the internal hollow cavity is divided into a central water inlet chamber 8 and an outer peripheral water outlet chamber 9. The outer peripheral water outlet chamber 9 is divided into a first water outlet chamber 10 and a second water outlet chamber 11. The first water outlet chamber 10 is connected to the central water inlet chamber 8 and the second water outlet chamber 11 respectively through openings arranged opposite to each other in the circumferential direction of the body 1.

[0038] By sequentially connecting the central water inlet chamber and two water outlet chambers through openings, and positioning these two openings opposite each other in the circumferential direction of the cylindrical water injection box, the first water outlet chamber acts as a buffer to cushion the water flow. This allows lower-pressure water to flow into the washing machine through the outlet in the first water outlet chamber, while higher-pressure water flows through the outlets in both the first and second water outlet chambers. This represents a significant technological advancement in regulating and diverting the water flow through the two sequentially connected water outlet chambers. Furthermore, because the two openings are located at opposite ends of the first water outlet chamber, the water flow can fully utilize the circumferential extension of the first water outlet chamber, increasing the flow channel length and enhancing the water injection box's effectiveness in regulating and stabilizing the water flow.

[0039] like Figures 1 to 2 As shown, in this embodiment, mounting ribs 15 are respectively provided on the side walls of both ends of the columnar water injection box body 1. The mounting ribs 15 extend along the tangential direction of the side wall of the columnar water injection box body 1, and the mounting ribs 15 at both ends are arranged in parallel. The middle part of the mounting rib 15 is connected to the body 1 of the columnar water injection box, and the two ends protrude from the side wall of the body 1 of the columnar water injection box. The mounting rib 15 is provided with through mounting holes for fixing devices such as bolts and claws to fix the water injection box.

[0040] In this embodiment, the columnar water injection box can be installed horizontally at the opening of the washing machine tub or vertically inside the washing machine tub, so that water can be injected into the washing machine tub through the water outlet opened on the side wall of the water injection box.

[0041] like Figures 1 to 8As shown, in this embodiment, the side wall of the columnar water injection box body 1 is provided with multiple first water outlets 4 and multiple second water outlets 5. Each first water outlet 4 is connected to a first water outlet cavity 10, and each second water outlet 5 is connected to a second water outlet cavity 11, for injecting water into the washing machine tub through the first water outlets 4 and the second water outlets 5. In this embodiment, the first water outlets 4 and the second water outlets 5 are both located on the other side of the columnar water injection box body 1 opposite to the mounting rib 15, so that the mounting rib 15 is connected to the washing machine tub and the water outlets face inwards towards the washing machine tub, avoiding obstruction of the water outlets by the mounting ribs, facilitating the injection of water into the washing machine tub by the water injection box, and allowing the injected water to be sprayed directly onto the clothes to be treated placed in the washing machine tub, thereby improving the water injection effect of the water injection box.

[0042] In this embodiment, the water injection box body 1 is provided with a water inlet 3 that is connected to the central water inlet cavity. The central water inlet cavity 8 is connected to the first water outlet cavity 10 through the first opening 6. The second opening 7 and the first water outlet 4 are located on the same side of the first water outlet cavity 10 in the circumferential direction of the columnar body 1.

[0043] With the above settings, the inlet water flow is preferentially directed to the first outlet, so that the inlet water flow with lower pressure can all be discharged through the first outlet, thereby reducing the outlet opening and increasing the water pressure at the outlet, thus achieving a stable water flow pattern under lower inlet water pressure.

[0044] In this embodiment, the water injection box body 1 is provided with a first water outlet 4 connected to the first water outlet chamber 10 and a second water outlet 5 connected to the second water outlet chamber 11. The first water outlet chamber 10 and the second water outlet chamber 11 are connected through a second opening 7. The second opening 7 and the first water outlet 4 are located on opposite sides of the first water outlet chamber 10 in the circumferential direction of the columnar body 1, and the second opening 7 and the second water outlet 5 are located on opposite sides of the second water outlet chamber 11 in the circumferential direction of the columnar body 1.

[0045] By setting the water outlets of the two water outlet chambers at the two ends of the annular water path formed by the outer annular water outlet chamber, the water flowing into the water outlet chamber is preferentially injected into the washing machine drum through the first water outlet. When the water pressure is too high, it is diverted to the second water outlet chamber and injected into the washing machine drum through both the second and first water outlets. This achieves a significant technological advancement in stabilizing and regulating the water flow into the washing machine.

[0046] like Figures 4 to 8As shown, in this embodiment, the body 1 has an annular rib 12 inside. The inner side of the annular rib 12 forms a central water inlet cavity 8, and the space between the outer side of the annular rib 12 and the inner side of the body 1 forms a peripheral water outlet cavity 9. The annular rib 12 has a first opening 6 that connects the central water inlet cavity 8 and the peripheral water outlet cavity 9. The peripheral water outlet cavity 9 has two baffles extending in different radial directions from one end of the columnar body 1 to the other end. The two baffles divide the peripheral water outlet cavity 9 into a first water outlet cavity 10 and a second water outlet cavity 11. The side walls of the columnar body 1 on both sides of the first baffle rib 13 have a first water outlet 4 and a second water outlet 5, respectively. The first opening 6 and the first water outlet 4 are both located on the same side of the first baffle rib 13. The second baffle rib 14 has a second opening 7 that connects the first water outlet cavity 10 and the second water outlet cavity 11 on both sides.

[0047] In this embodiment, the two baffles are located on different sides of the annular outer peripheral water outlet cavity 9, and the included angle between the two baffles is 180 to 90 degrees. More preferably, the included angle between the two baffles is between 100 and 170 degrees, so that the two baffles divide the annular outer peripheral water outlet cavity 9 into two parts of unequal size. The larger part between the two baffles is the first water outlet cavity 10, and the smaller part is the second water outlet cavity 11. This makes the space of the first water outlet cavity 10, which constitutes the flow stabilization function, larger, further improving the pressure regulation effect. At the same time, since the second water outlet cavity 11 is located downstream of the first water outlet cavity 10, the space of the downstream cavity is set to be smaller than that of the upstream cavity, which can ensure the water pressure balance of the two water outlet cavities, thereby achieving consistency of the water flow from the two sets of different outlets.

[0048] In this embodiment, one end of the columnar body 1 is open and the other end is closed. The open end is provided with a corresponding end cap 2 that closes the open end. The end cap 2 is fixedly connected to the columnar body 1 to seal one end of the internal cavity of the columnar body 1.

[0049] like Figures 1 to 8 As shown, in this embodiment, one end of the columnar body 1 is a detachable end cap 2. The end cap 2 has a connector 16 that extends coaxially into the central water inlet cavity from the end. The internal channel of the connector 16 forms a water inlet 3. The outer wall of the part of the connector 16 that extends into the central water inlet cavity 8 is in sealed contact with the inner wall of the annular rib 12. The first opening 6 is located at one end of the annular rib 12 and on the same side as the end cap 2. At least a part of the first opening 6 is staggered with the connector 16 to connect the central water inlet cavity 8 and the first water outlet cavity 10.

[0050] In this embodiment, the contact between the end cap 2 and the body 1 is sealed; preferably, the end cap 2 and the body 1 are fixedly connected by a cladding process.

[0051] In this embodiment, the two ends of the first baffle 13 are respectively sealed to the two ends of the outer peripheral water outlet cavity 9 to isolate the two sides; there is a gap between the end of the second baffle 14 and the end cap 2, and the gap forms a second opening 7 that connects the first water outlet cavity 10 and the second water outlet cavity 11, which is used to divert the excessive water flow in the first water outlet cavity 10 to the second water outlet cavity 11; the second opening 7 is on the same side as the end cap 2, so that the second opening 7 is set at the place with the maximum water pressure in the outer peripheral water outlet cavity 9, thereby improving the pressure distribution and flow rate effect of the water injection box.

[0052] like Figures 1 to 8 As shown, in this embodiment, a row of water outlets is provided at different radial positions on the sidewall of the columnar body 1. The first row of water outlets includes a plurality of first water outlets 4 arranged at intervals along the axial direction, and the second row of water outlets includes a plurality of second water outlets 5 arranged at intervals along the axial direction. Preferably, the first row of water outlets and the second row of water outlets can be arranged side by side or staggered.

[0053] like Figure 7 and Figure 8 As shown, in this embodiment, each of the first water outlets 4 in the first column is a straight hole 17 with an opening axis arranged radially along the columnar body 1; at least some of the second water outlets 5 in the second column are oblique holes 18 with an opening axis arranged inclined radially along the columnar body 1. Through the above arrangement, the different groups of water outlets are differentiated so that the two groups of water outlets provide different water patterns, making the water flow of the water injection box more uniform and the spraying effect on clothes better.

[0054] Preferably, the second outlets 5 in the second column have an increasing angle of inclination from the middle of the columnar body 1 to both ends, and the inclination direction on both sides is inclined outward to the corresponding side, so as to expand the coverage of the water flow.

[0055] Further preferred, such as Figure 7 and Figure 8 As shown, each second water outlet 5 in the middle of the second column is a straight hole 17 with an opening axis set radially along the columnar body 1; each second water outlet 5 on the left side is an oblique hole 18 with the opening axis inclined to the left along the water outlet direction, and the inclination angle of the oblique hole 18 increases sequentially as it moves further away from the middle of the columnar water injection box body 1; each second water outlet 5 on the right side is an oblique hole 18 with the opening axis inclined to the right along the water outlet direction, and the inclination angle of the oblique hole 18 increases sequentially as it moves further away from the middle of the columnar water injection box body 1. Preferably, the inclination angle between the opening axis of the oblique hole 18 and the radial direction of the body 1 is 5 to 10 degrees.

[0056] In this embodiment, the diameters of the first water outlet 4 and the second water outlet 5 can be set to be equal or different. The specific design can be selected by combining parameters such as the number of water outlets and the model of the washing machine. The preferred diameter range of the water outlet is between 2 and 5 mm.

[0057] Preferably, in this embodiment, the outer end of the water outlet is provided with a guide rib that protrudes outward from the outer wall of the columnar body 1 and is arranged around the opening of the water outlet, so as to guide the water flow out of the water outlet and improve the water shape effect of the water injection box (not shown in the figure).

[0058] Meanwhile, this embodiment also introduces a washing machine, which includes any of the washing machine water injection boxes described above. The water inlet 3 of the water injection box is connected to the washing machine water inlet structure. Each first water outlet 4 and each second water outlet 5 of the water injection box are opened towards the inner tub of the washing machine, so that the water flow of the washing machine can enter the inner tub of the washing machine through the water injection box and directly act on the load to be processed in the inner tub of the washing machine.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
