[ detailed description of the invention ]

The container 10 shown in fig. 1 may be used in a washing device, such as a washer, washer-dryer, dishwasher, etc. The container 10 may be a detergent addition container of a washing apparatus or a laundry treatment container.

The container 10 has a tank body 11 with an open top, and a cover body 12 attached to the top of the tank body 11. The water supply line 13 is connected to the cover 12. The water from the water flow input pipeline 13 enters the tank body 11 after being guided by the cover body 12, and participates in the dissolution of detergent or the washing of washing objects such as clothes, tableware and the like.

The cover 12 contains a water distribution device 20. The water distribution device 20 comprises a water passage 21 connected to the inlet pipe 13 and an outlet 22 at the bottom of the cover 12. The water flow is fed from the water flow inlet pipe 13, passes through the water flow channel 21 in the cover 12, and finally enters the interior of the tank body 11 from the outlet 22.

The number of the outlets 22 may be one or plural. It is preferable that a plurality of outlets 22 be provided in the bottom of the flat plate-like lid 12. The plurality of outlets 22 are preferably arranged in a distributed, more preferably evenly distributed, arrangement.

Referring to fig. 2, the structural features of the water distribution device 20 in the embodiment shown in the figure can be understood. It can be seen that the water distribution device 20 comprises a body 25 in the form of a flat plate formed by the abutment of an upper wall 23 and a lower wall 24. In this embodiment, it is the cover 12 itself that forms the water distribution device 20. In other embodiments not shown by the figures, the water flow distribution means may also be part of the cover.

As shown in fig. 2, the upper portion of the lower wall 24, i.e., the surface opposite the upper wall 23, has radially extending and interconnected grooves 26. The upper wall 23 is fixedly connected to the lower wall 24, and a water flow passage 21 is formed in the groove 26. In various embodiments, slots may be provided at positions of the upper wall 23 corresponding to the slots 26 on the lower wall 24, or the slots 26 may be provided only at the upper wall 23 or only at the lower wall 24.

The water flow passage 21 includes a water inlet passage 211 and a plurality of water outlet passages 212. The water inlet channels 211 and the plurality of water outlet channels 212 are radially distributed and are respectively connected through a connection region 213 located in the central region. The lower wall 24 is provided with a plurality of outlets 22 corresponding to the water outlet channels 212. The inlet pipe 13 communicates with the water inlet passage 211. Thus, water from the input pipe 13 first enters the water inlet channel 211, then passes through the water outlet channels 212, and finally flows downwards from the outlet 22 of the water outlet channels 212 into the tank body 11.

As shown in fig. 2 to 4, the groove 26 is elongated. In particular, the groove 26 forming the water inlet passage 211 is elongated and has a constricted section 30 in the direction of water flow. In the constriction 30, the cross-section of the groove 26 is gradually reduced and then gradually enlarged. Accordingly, the cross-sectional area of the water inlet passage 211 at the position of the contraction section 30 is gradually reduced and then gradually enlarged. The water flow channel 21 corresponding to the contraction section 30 is connected with a vent pipe 31. The vent pipe 31 communicates the inside of the water flow passage 21 with the atmosphere. Wherein the vent tube 31 is located on the upper wall 23 and extends radially upward. The inner diameter of the vent pipe 31 is preferably small so that water does not overflow the vent pipe 31 when passing through the vent pipe.

Thus, water passing through the water flow passage 21 formed in the main body 25 of the water flow distribution device 20 must first pass through the constricted section 30. As the water flows through the constriction 31, the flow rate increases, where a negative pressure is created, thereby drawing air from the air duct 31. The inhaled air is mixed with water to form a large number of micro-bubbles. The water flow mixed with the fine bubbles flows into the housing 11 from the outlet 22 of the water flow path 21. The water containing the micro-bubbles can then directly interact with the objects in the container 10. For example, the microbubbles may break upon entering the container 10, the force generated by the break may accelerate dissolution of the detergent, or the force generated by the break of the bubbles may accelerate detachment of stains from the laundry if the laundry is contained in the container.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
