Spray equipment and washing machine according to the utility model some embodiments are described referring to Fig. 1 to Figure 12.

As shown in Figure 1 to 11, the spray equipment 1 that the embodiment of the utility model first aspect provides, comprising: water inlet is logical Road 10 and spray head 20.

Specifically, intake tunnel 10 has water inlet end and water outlet；Spray head 20 is connected with water outlet, and can be around water inlet The axis in channel 10 rotates, and its lateral wall is equipped with the nozzle 211 being connected with intake tunnel 10；Wherein, the number of nozzle 211 It is multiple for measuring, and multiple nozzles 211 are multilayer along the axis direction arrangement of intake tunnel 10.

The specific structure of spray equipment 1 provided by the present application is described in detail below with reference to some embodiments.

Embodiment one

The stepped structure of the lateral wall of spray head 20, the cascaded surface that step structure has multiple radial dimensions different 21, as shown in Figure 1 to Figure 3, multilayer nozzle 211 is distributed on multiple cascaded surfaces 21, and multilayer nozzle 211 is made to have multiple sprays half Diameter.

The lateral wall of spray head 20 is designed as step structure, makes it have the different cascaded surface of multiple radial dimensions 21, multilayer nozzle 211 is distributed on multiple cascaded surfaces 21, so that the spray radius of every layer of nozzle 211 is not also identical, then it is same The spray space of moment multilayer nozzle 211 in radial directions can be complementary to one another, this week equivalent to increase spray equipment 1 The effect of water conservation is further improved to spray radius so that the spray solid space of spray equipment 1 is more comprehensive Fruit.

Further, the quantity of every layer of nozzle 211 and the radial dimension of this layer of 211 place cascaded surface 21 of nozzle are positively correlated, As shown in Figure 1 and Figure 4.

The quantity of every layer of nozzle 211 and the radial dimension of this layer of 211 place cascaded surface 21 of nozzle are positively correlated, it may be assumed that cascaded surface 21 radial dimension is bigger, and the quantity of the nozzle 211 on the cascaded surface 21 is more, and the radial dimension of cascaded surface 21 is smaller, the rank The quantity of nozzle 211 on tread 21 is fewer.In this way, the quantity of nozzle 211 is adapted with the area of cascaded surface 21 where it, have Rationally nozzle 211 is set conducive to according to the specific size of cascaded surface 21, guarantees the suitable and adjacent spray of each 211 size of nozzle There is suitable distance between mouth 211, and then optimize product structure and performance.

Preferably, along the direction for being directed toward water outlet by water inlet end, the radial dimension of cascaded surface 21 is gradually reduced, extremely such as Fig. 1 Shown in Fig. 4.

Along the direction for being directed toward water outlet by water inlet end, the radial dimension of cascaded surface 21 is gradually reduced, then sprays on vertical direction The big nozzle 211 of leaching radius is relatively top, and the water flow sprayed is relatively outer, sprays the small nozzle 211 of radius relatively on the lower, The water flow of ejection is relatively inner, so the water flow that each layer nozzle 211 sprays will not interfere with each other, so that each layer nozzle 211 sprays Water flow can farthest play its cleaning efficiency, to further increase cleaning efficiency, further increase saving and use The effect of water.

Further, the quantity of every layer of nozzle 211 is multiple, and every layer of multiple nozzles 211 are about intake tunnel 10 Axial-rotational Symmetry, as shown in Figure 4.

The quantity of every layer of nozzle 211 is multiple, and every layer of multiple nozzles 211 are revolved about the axis of intake tunnel 10 Turn symmetrical, not only improve 20 stress equalization of spray head, so that improving it rotates reliability, reduces the risk of rotation failure；Make again It is more uniform in circumferential direction to obtain the water that spray equipment 1 sprays, to improve uniform spraying, further improves cleaning Efficiency；Make the structure of product more regular simultaneously, molding easy to process.

Further, all nozzles 211 along intake tunnel 10 Axial-rotational Symmetry, as shown in figure 4, with as much as possible Improve the rotation reliability of spray head 20.

Further, multiple nozzles 211 of adjacent two layers are arranged in a staggered manner along the circumferential direction of spray head 20, as shown in Figure 4.

The nozzle 211 of adjacent two layers is arranged in a staggered manner along the circumferential direction of spray head 20, can be avoided two layers adjacent of spray The water flow that mouth 211 sprays interferes with each other, then the spray space of synchronization multilayer nozzle 211 in circumferential direction can be mutually complementary It fills, so that the spray solid space of spray equipment 1 is more comprehensive, further improves the effect of water conservation.

Specifically, multiple nozzles 211 are divided into two layers along the axis direction of intake tunnel 10, as shown in Figures 1 to 4.

Axis direction by multiple nozzles 211 along intake tunnel 10 is divided into two layers, so that the number of plies of nozzle 211 is reduced to most It is few, the structure of spray equipment 1 is significantly simplified, save the cost is conducive to；And two layers of nozzle 211 in circumferential direction with radial side It is easy to accomplish upwards to be staggeredly arranged, to not only meet the needs for increasing spray solid space, but also reduce design difficulty.

Certainly, the number of plies of nozzle 211 is not limited to two layers, or three layers, four layers of even more multilayer, in actual production It can according to need and be adjusted in the process.

Embodiment two

Difference with embodiment one is: on the basis of example 1, further, the axis direction phase of nozzle 211 The inclined of spray head 20 is extended, as shown in Figures 1 to 4, enables spray head 20 around the axis of intake tunnel 10 Line spinning.

Extend the axis direction of nozzle 211 relative to the inclined of spray head 20, then it can be right when water flow sprays Nozzle 211 applies reversed active force and spray head 20 is driven to rotate, for example when water flow sprays along clockwise direction, sprays driving Leaching head 20 is rotated in the counterclockwise direction, to realize the spinning of spray head 20, is revolved without additional installation driving spray head 20 The structure turned, to simplify product structure, and has saved energy consumption, further reduced the use cost of product.

Further, the axis direction of nozzle 211 coils setting, shape along the axis direction of intake tunnel 10 in the shape of a spiral At spiral nozzle 211, as shown in Figure 1 and Figure 4.

So that the axis direction of nozzle 211 is coiled setting in the shape of a spiral along the axis direction of intake tunnel 10, forms spiral Nozzle 211, it may be assumed that the axis of nozzle 211 is the three-dimensional helix (difference extended along the axis direction inclination of intake tunnel 10 In gradually outwardly extending helix in plane, it is equivalent to one section of the helix of spring), so the water outlet of spiral nozzle 211 Mouth protrudes from the outside wall surface of spray head 20, it is thus possible to which the circumferential spray radius for increasing spray equipment 1 brings bigger spray empty Between, to further increase cleaning efficiency, further increase the effect of water conservation.

Further, the hand of spiral of the axis of two layers of nozzle 211 is identical, as shown in Figure 1 and Figure 4, to guarantee spray head 20 can realize spinning under the reaction force of water flow；And spray equipment 1 is made to become 360 ° of automatic rotation sprays of double-screw type Shower device 1 can bring more efficient cleaning effect.

Further, the water outlet of spiral nozzle 211 is towards the direction close to water outlet, as depicted in figs. 1 and 2.

The water outlet of spiral nozzle 211 is towards the direction close to water outlet, then (spray equipment 1, which is assembled to, to be washed in vertical space After in clothing machine 2, intake tunnel 10 is general to be extended along the vertical direction or close to vertical direction) in, the water outlet court of spiral nozzle 211 Obliquely upward, the water flow that such spiral nozzle 211 sprays can be inclined outwardly ejection upwards, then fall still further below, thus further Spray equipment 1 is increased in the spray space of vertical direction, and the skyborne flowing time of water flow can be increased, and then further Cleaning efficiency is improved, the effect of water conservation is further increased.

Preferably, the angle between the central axis of the water outlet of spiral nozzle 211 and the cross section of intake tunnel 10 exists In the range of 3 ° -10 °.

The water outlet of spiral nozzle 211 central axis (i.e. by spiral nozzle water outlet where plane center and Perpendicular to spiral nozzle water outlet where plane straight line) with the cross section of intake tunnel 10 between angle, it may be assumed that water inlet lead to When road 10 extends along the vertical direction, angle between the central axis and horizontal plane of water outlet, the angle determines water flow in water The relative size of component velocity in square upward component velocity and vertical direction: if the angle is excessive, it will lead to water flow level The component velocity in direction is too small, and then is reduced significantly the spray radius of nozzle 211；It will lead to vertical direction if the angle is too small Component velocity is too small, is unfavorable for increasing the spray space of spray equipment 1 in the vertical direction.Therefore, spiral nozzle 211 is rationally designed The central axis of water outlet and the cross section of intake tunnel 10 between angle it is particularly significant.The technical staff of our company passes through It is found after test of many times and research, it will be between the central axis of the water outlet of spiral nozzle 211 and the cross section of intake tunnel 10 Angle control in the range of 3 ° to 10 °, have preferable resultant effect.Certainly, its specific structure of different products is different, Requirement to spray equipment 1 is also not quite similar, so the cross of the central axis of the water outlet of spiral nozzle 211 and intake tunnel 10 Angle between section is not limited to above range, can according to need be adjusted in the actual production process.

Embodiment three
