[0025] like Figures 1 to 4 As shown, a drum vector spray system includes a drum 1 and a spray mechanism disposed in the drum 1, which can realize all-round and uniform wetting of clothes, and can make the clothes in the middle of the drum 1 during the washing process, thereby improving the washing efficiency and effect. The spray mechanism of this embodiment includes a vector spray assembly 2 and a counter-spray assembly 3 arranged oppositely, so that this embodiment can spray washing water from two opposite sides of the clothes at the same time, thereby achieving complete wetting of the clothes, and can also make the clothes be pushed to the middle position of the drum 1 during the spraying process, thereby improving the washing effect of the clothes.

[0026] Specifically, the vector jet assembly 2 of the present embodiment is sealedly mounted on the rotating shaft position inside the drum 1, and can simultaneously spray washing water in multiple angles, thereby improving the wetting effect of clothes; the opposing jet assembly 3 of the present embodiment is fixedly mounted on the opening 13 position of the drum 1 opposite to the vector jet assembly 2, and the spraying direction is toward the inside of the drum 1, so that when the vector jet assembly 2 sprays washing water from one side of the drum 1, the opposing jet assembly 3 can simultaneously spray washing water from the other side, thereby improving the overall wetting effect of clothes, and can make the clothes be pushed to the middle position of the drum 1 under the action of the relative spraying on both sides, avoiding close contact with the side wall of the drum 1, so that the clothes can be completely rubbed by the inner wall of the drum 1 when the drum 1 rolls, thereby improving the washing effect of the clothes.

[0027] like Figure 2 As shown, the vector spray assembly 2 of this embodiment includes a mounting base 21 and a plurality of first spray heads 22 symmetrically mounted on the surface of the mounting base 21 in pairs, wherein the mounting base 21 is connected to the axial position of the drum 1 and is connected to the first spray heads 22 for water supply, so that this embodiment can spray clothes in multiple directions from the inside of the drum 1 through the plurality of first spray heads 22, thereby improving the wetting effect of the clothes.

[0028] Specifically, the mounting base 21 of the present embodiment includes an integrally formed connecting portion 211 and a mounting portion 212, wherein the connecting portion 211 is connected to the rotating shaft of the drum 1, and the mounting portion 212 extends toward the inside of the drum 1 and is located inside the drum 1, so that the water spray system of the present embodiment can spray washing water from the inside of the drum 1 for cleaning; and, a plurality of first nozzles 22 of the present embodiment are symmetrical in pairs and surround the surface of the mounting portion 212, so as to facilitate the multi-directional spraying function of the present embodiment.

[0029] The connection between the connecting portion 211 of this embodiment and the axial position of the drum 1 is a sealed connection, which can not only realize the stable installation of the vector spray assembly 2, but also prevent the washing liquid inside the drum 1 from leaking, thereby ensuring the normal operation of the washing machine. Specifically, a mounting channel is provided at the axial position of the drum 1 of this embodiment, and the connecting pipe is tightly inserted into the mounting channel, so that the vector spray assembly 2 can be stably installed; at the same time, a connecting bearing is installed in the mounting channel, and the connecting pipe is inserted into the connecting bearing, so that when the drum 1 rotates to wash the clothes, the connecting pipe can remain stationary under the action of the connecting bearing, which can prevent the vector spray assembly 2 from rotating with the drum 1 and causing abnormal water spray or damage.

[0030] like Figure 1 and Figure 2As shown, the mounting portion 212 of the present embodiment may be a structure such as a cone or a hemisphere, the outer diameter of which gradually decreases from one end close to the connecting portion 211 to the end extending toward the inside of the drum 1, and a plurality of first nozzles 22 are symmetrically arranged in pairs around the inclined surface of the mounting portion 212, so that each first nozzle 22 can be directed in multiple directions under the action of the inclined surface of the mounting portion 212, thereby realizing the energy supply of multi-directional injection of the present embodiment; at the same time, the first nozzles 22 of the present embodiment are symmetrically arranged in pairs, so that during the washing process of the clothes, the symmetrically arranged first nozzles 22 can spray on two opposite surfaces of the clothes at the same time, which is convenient for realizing vector balance, thereby improving the washing effect of the clothes.

[0031] like Figure 2 As shown, in order to supply water to the first nozzle 22 and realize the water spraying function of the first nozzle 22, a cavity 213 connected to the water supply pipeline of the washing machine is provided in the mounting base 21 of the present embodiment, and a plurality of mounting holes which are symmetrically arranged in pairs and connected to the cavity 213 are provided on the surface of the mounting portion 212. By fixing the first nozzle 22 in the mounting hole, water can be supplied to the first nozzle 22 through the cavity 213, thereby realizing the multi-directional spraying function of the vector spray assembly 2 of the present embodiment.

[0032] In one embodiment, the cavity 213 can be used as a water supply cavity 213 to be directly connected to the water supply pipe inside the washing machine, that is, the washing machine directly passes water into the cavity 213 to centrally supply water to all the first nozzles 22, thereby realizing the water spraying function of each first nozzle 22.

[0033] In another embodiment, the cavity 213 can be used as an installation cavity, and the water supply pipeline of the washing machine is split into multiple branch pipes connected to the cavity 213, and respectively connected to the connection positions of each first nozzle 22 plugged into the cavity 213, thereby not only realizing the function of the first nozzle 22 spraying water at the same time, but also realizing the ability of each nozzle to spray separately by controlling each branch pipe.

[0034] like Figure 1 and Figure 3 As shown, the opposing spray assembly 3 of this embodiment includes at least two groups of spray heads 31, and both groups of spray heads 31 are arranged toward the inside of the drum 1, so as to form an opposing spray structure with the first spray head 22 of the vector spray assembly 2, so that the clothes in the drum 1 can be pushed to the middle position of the drum 1 under the action of the spray heads 31 and the first spray head 22, so as to avoid contact with the side wall of the drum 1 and thus affecting the washing effect. Specifically, the two groups of spray heads 31 of this embodiment are symmetrically arranged at the top and bottom or left and right sides of the opening 13 of the drum 1, so that when the opposing spray assembly 3 sprays, it can also perform relative spraying through the two groups of spray heads 31, thereby improving the spraying and washing effect of the clothes; in another embodiment, the spray heads 31 can also be arranged in four groups, and are respectively arranged at the upper and lower sides and the left and right sides of the opening 13 of the drum 1, which can further improve the spraying effect on the clothes.

[0035] like Figure 3 As shown, the spray head 31 of this embodiment includes a plurality of second spray heads 311 arranged equidistantly, and each second spray head 311 is arranged toward the inside of the drum 1 and inclined toward the axis of rotation of the drum 1, so that the washing water sprayed by the spray head 31 can form a cone structure with the tip gathered toward the axis, which can not only achieve sufficient wetting of the clothes, but also improve the overall force of the spray component 3 when spraying, so as to facilitate pushing the clothes to the middle position of the drum 1.

[0036] like Figures 1 to 4 As shown, the drum 1 of this embodiment includes an outer drum 11 and an inner drum 12 rotatably installed in the outer drum 11. When washing clothes, the inner drum 12 rotates in the outer drum 11 under the action of the motor, so as to achieve the washing effect; the vector injection assembly 2 of this embodiment is installed at the axis of the inner drum 12, and the opposite injection assembly 3 is arranged at the position of the port 13 of the inner drum 12, so as to facilitate the first clothes placed in the inner drum 12 to be injected; wherein, a water collecting filter box 111 is provided at the bottom of the outer drum 11 of this embodiment, which can recover and filter the washing water after washing the clothes, wherein the vector injection assembly 2 and the opposite injection assembly 3 are both connected to the water collecting filter box 111, so that the washing water after the initial washing of the clothes can be supplied to the vector injection assembly 2 and the opposite injection assembly 3 after filtration to spray the clothes for secondary washing, which can reduce the water consumption.

[0037] like Figure 1 and Figure 4 As shown, a cleaning spray assembly 4 is fixedly installed on the wall of the outer cylinder 11 of the present embodiment, wherein the cleaning spray assembly 4 is arranged toward the outer wall of the inner cylinder 12, and can clean the outer wall of the inner cylinder 12 to keep the outer wall of the inner cylinder 12 clean, thereby avoiding the breeding of bacteria; and, when the cleaning spray assembly 4 of the present embodiment sprays toward the outer wall of the inner cylinder 12, the sprayed liquid or gas can also be reflected through the outer wall of the inner cylinder 12 to the inner wall of the outer cylinder 11, thereby cleaning the inner wall of the outer cylinder 11 and some narrow spaces that are not easily affected by water.

[0038] At the same time, a hole is provided on the wall of the inner drum 12 of the present embodiment, and the cleaning spray component 4 can spray the clothes close to the inner wall of the inner drum 12 through the inner drum hole, thereby spraying the bottom surface of the clothes that the vector spray component 2 and the opposite spray component 3 cannot spray, thereby improving the spray efficiency and cleaning effect of the clothes.

[0039] Specifically, the cleaning spray assembly 4 of the present embodiment is symmetrically arranged on both sides of the water collecting filter box 111 and on both sides of the top symmetrically through the central axis, which can not only improve the cleaning effect on the outer wall of the inner drum 12, but also realize the opposite balanced spraying of the clothes close to the inner wall of the inner drum 12, thereby improving the wetting efficiency of the clothes and improving the washing effect of the clothes.

[0040] In summary, the beneficial effects of this embodiment are as follows: this embodiment arranges a vector spray assembly 2 at the rotating shaft position of the drum 1, and arranges an opposite spray assembly 3 opposite to the vector spray assembly 2 at the opening 13 of the drum 1, so that during the washing process of clothes, the vector spray assembly 2 can spray washing water in multiple directions from the inside of the drum 1, and at the same time the opposite spray assembly 3 can spray washing water from the other side of the drum 1, so that the clothes can be fully and evenly wetted, and the simultaneous spraying of the vector spray assembly 2 and the opposite spray assembly 3 can also keep the clothes in the middle of the drum 1 for easy washing.
