Detailed Description
First, it should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although the spraying apparatus of the present invention is described in conjunction with a pulsator washing machine and a drum washing machine, this is not limitative, and other apparatuses having a need for laundry drying may be configured with the spraying apparatus of the present invention, such as a twin-tub semi-automatic washing machine.
Next, it should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "inside", "outside", and the like are based on the direction or positional relationship shown in the drawings, which are only for convenience of description, and do not indicate or imply that the device or member must have a specific orientation, be constructed in a specific orientation, and operate, and thus, should not be construed as limiting the present invention.
Furthermore, it should be noted that, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The existing fully automatic washing machines, such as pulsator washing machine and drum washing machine, include an inner tub and an outer tub, wherein the inner tub is a washing tub. When washing clothes, firstly, a detergent is dissolved in water to dissolve and decompose stains on the clothes; then, the laundry is rinsed and dehydrated a plurality of times. The existing full-automatic washing machine generally adopts constant-volume rotary rinsing, namely clean water is used for replacing sewage with residual detergent and stains in clothes for many times, so that the content of the residual detergent and the stains in the clothes is gradually reduced, and the washing and cleaning of the clothes are further completed.
In the whole washing process, the washing time is not large, most of the time of the whole washing process is consumed in the dewatering rinsing stage, so that a large amount of time, water, electric energy and the like are wasted, taking a fusion type washing machine as an example: the two-time rinsing and dewatering time in the default cotton and linen washing program occupies about 55% of the total washing time, so that the total washing time can be shortened, and the washing efficiency can be improved.
In view of this, the spraying device is installed at the clothes feeding port of the washing cylinder, the spraying device comprises a first water inlet branch pipe and a spraying head which are communicated, and the spraying head is provided with a long-strip-shaped spraying port which extends along the axial direction of the washing cylinder, so that a water curtain sprayed out of the spraying port can cover one bus of the washing cylinder. The invention adopts flowing clean water to replace fixed volume water to spray the dehydrated clothes in the rinsing process, continuously updates water in the clothes under the action of centrifugal force in the dehydrating process, and discharges the sewage with detergent and stains dissolved in the clothes, thereby achieving the purpose of cleaning the clothes.

The spray head 1 of the spray device is arranged at the first clothes input port 41 of the first washing cylinder 4, and the spray port 11 of the spray head 1 extends along the axial direction of the first washing cylinder 4. The spraying opening 11 can be parallel to the axial direction of the first washing cylinder 4, and the spraying opening 11 can also be inclined at a certain angle relative to the axial direction of the first washing cylinder 4. The thickness range of the dehydrated clothes 6 attached on the inner wall of the first washing drum 4 is between the drum wall of the first washing drum 4 and a position which is half of the distance from the center of the first washing drum 4; the maximum depth range of the dehydrated clothes 6 is about 4/5h (wherein h is the depth of the washing barrel) of the barrel of the pulsator washing machine, and the spraying range of the spraying water curtain 7 is taken as the maximum depth range. The installation position of the spray header 1 on the horizontal plane of the first clothes input port 41 is not limited in the invention, and the spray header can be set by a person skilled in the art according to the actual situation.
Referring to fig. 2, a washing tub of the drum washing machine is defined as a second washing tub 5, and a laundry input port thereof is a second laundry input port 51.

At this time, all the spray headers 1 share one control valve 3, so that the complexity of the connection of the main control circuit board can be reduced, and the complexity of the control program of the washing machine can be reduced.
When the pulsator washing machine is provided with a plurality of spray headers 1, for example, two, three, four spray headers 1, etc., at the first input port 41, the plurality of spray headers 1 may be uniformly spaced along the circumference of the first washing tub 4.
When the plurality of spray heads 1 are arranged at the second input port 51 of the drum washing machine, the installation positions of the plurality of spray heads 1 need to consider the water flow potential energy change and the balance problem of the spray point position to the centripetal force of the second washing cylinder 5 when the second washing cylinder 5 is dehydrated. Referring to fig. 3, when two shower heads 1 are installed at the second input port 51, the two shower heads 1 are symmetrical with respect to the vertical diameter of the second washing tub 5, and the two shower heads 1 are located at the upper side of the horizontal diameter of the second washing tub 5.
