Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can
To be combined with each other.
In the present invention, it is to be understood that term "vertical", "horizontal", " direction ", " deviating from ", "upper", "lower", " diameter
To ", the orientation or positional relationship of the instructions such as " circumferential direction " it is corresponding with the orientation or positional relationship of actual use；The orientation used
Word such as " left and right " is typically referred to reference to shown in the drawings left and right；" inside and outside " refer in the profile relative to each component itself,
Outside；It is merely for convenience of description of the present invention and simplification of the description, rather than indicates that signified device or element must have specifically
Orientation is constructed and operated in a specific orientation, therefore is not considered as limiting the invention.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiment.
According to an aspect of the present invention, a kind of rotary drum washing machine is provided, as depicted in figs. 1 and 2, the rotary drum washing machine packet
It includes:
Dehydration barrel 1；
Impeller 4, the impeller 4 are set to the inside bottom of the dehydration barrel 1, and the inside bottom of the dehydration barrel 1
A barrel bottom gap water containing chamber 6 is limited between the impeller 4；
Water spraying mechanism, the water spraying mechanism include multiple injections in the circumferentially spaced setting in top of the dehydration barrel 1
Water containing chamber 8；
Multiple to cross water flow passage 7, multiple water flow passages 7 of crossing are corresponded with multiple injection water containing chambers 8 to connect respectively
Lead to each injection water containing chamber 8 and bucket bottom gap water containing chamber 6；
It is provided in bucket bottom gap water containing chamber 6 described for driving the water in bucket bottom gap water containing chamber 6 to pass through
It crosses water flow passage 7 and enters the drainage mechanism of the injection water containing chamber 8.
Wherein, each injection water containing chamber 8 be separately positioned on the corresponding top for crossing water flow passage 7 and from pair
The circumferentially extending crossed at water flow passage 7 along the dehydration barrel 1 answered, the cross section of each injection water containing chamber 8 is along remote
It is gradually reduced on circumferentially extending direction from the mistake water flow passage 7；
It is each it is described injection water containing chamber 8 be provided with along the dehydration barrel 1 circumferentially extending and can be towards the dehydration barrel 1
The water jet 801 of inside water spray.
In rotary drum washing machine according to the present invention, in laundering process, impeller 4 rotates forward or backwards, stirs water
It flows and clothing is driven to rotate, while the water in drainage mechanism driving bucket bottom gap water containing chamber 6 crosses water flow passage 7 by each, then
It into each injection water containing chamber 8, and is finally sprayed in dehydration barrel 1 by water jet 801, to be formed from the top of dehydration barrel 1
The spray waterfall water flow circumferentially sprayed；Wherein, since the cross section of injection water containing chamber 8 is along far from the circumferential direction for crossing water flow passage 7
It is gradually reduced on extending direction, so that from water flow passage 7 is crossed into the water flow in injection water containing chamber 8 along injection water containing chamber 8
When circumferentially extending direction flowing, resistance is gradually increased, in this way can be to avoid the separated place water flow mistake of adjacent injection water containing chamber 8
Greatly, and for an injection water containing chamber 8, water yield and the hydraulic pressure for extending along each position in direction are as uniform as possible
Change, so that water jet 801 homogenizes as much as possible along the water flow that each position in the circumferentially extending direction of dehydration barrel 1 sprays.Cause
This, technical solution provided by the invention not only can make water flow inwardly spray in the circumferential direction of dehydration barrel, so as to be formed
