Embodiment 1

[0032] A dishwasher provided by the present invention includes a shell and an inner container. The interior of the inner container is a cleaning room for cleaning tableware. There is a tableware input port in front of the inner container, and a door body is installed at the tableware input port. A shelf is installed in the inner tank, and tableware such as dishes are placed on the shelf when washing dishes. The dishwasher also includes a spray system, including a water pump, a water tank, a filter screen, a waterway, at least one spray arm 1 installed inside the liner, and the like.

[0033] Such as figure 1 As shown, one spray arm 1 can be installed on the upper, middle and lower parts of the inner container respectively, and the spray arm 1 can be fixed to realize static spray, or it can be rotated in the horizontal plane to realize rotary spray. shower. A plurality of nozzles 2 are arranged on each spray arm 1 to ensure the spray effect, and the plurality of nozzles 2 are...

Embodiment 2

[0038] Such as Figure 3 to Figure 5 As shown, the difference from Embodiment 1 is that in this embodiment, the nozzle 2 is a hollow disc-shaped structure, and a spray hole 3 is opened at the bottom of the nozzle 2, and a spray hole 3 is opened on each nozzle 2, A deflector is arranged at the front end of each spray hole 3, and there is a certain gap 5 between the deflector and the spray hole 3, and the washing water flows out from the gap 5, and the deflector and the nozzle 2 can be opposite to each other. Movement can change the size of the gap 5 between the flow guiding device and the spray hole 3 .

[0039] In this embodiment, the deflector includes an umbrella-shaped deflector 7 at the top and a base 8 at the bottom. The deflector 7 and the base 8 are integrally injection molded, and the bottom of the vertical rod of the deflector 7 is connected to the base 8 . The base 8 is fixed on the nozzle 2 through the connecting piece 15 , and the base 8 can also be fixed on the s...

Embodiment 3

[0043] Such as Figure 5 and Figure 6 As shown, the difference from Embodiment 1 and Embodiment 2 is that the flow guiding device is a columnar body 10, which is arranged horizontally corresponding to the spray hole 3, and the columnar body 10 is fixed on the nozzle 2, and the spray hole 3 and the columnar body 10 There is a gap 5 on the outer peripheral surface. In this embodiment, the nozzle 2 is a cuboid structure, and a long spray hole 3 is opened on the nozzle 2 along the transverse direction, and the corresponding columnar body 10 as a flow guiding device is a slender cylinder with a long strip shape. The gap 5 between the spray hole 3 and the columnar body 10 is strip-shaped, and when the washing water flows out from the gap 5, it is also sprayed in a divergent form. The divergent form is generally in the form of a continuous water curtain, and it Correspondingly, the area of ​​water spraying is increased, which can avoid the occurrence of washing dead ends. Several...

Abstract

The invention relates to a dish washing machine spraying device and a dish washing machine provided with the spraying device. The dish washing machine spraying device comprises at least one nozzle, each nozzle is provided with at least one spraying hole, a diversion device is arranged at the front end of at least one spraying hole, washing water flows out of water flow of the washing water in being sprayed in a diverged mode. Under the effect of the diversion device, the washing water flowing from the spraying hole is sprayed out in a diverged mode, the existence of a washing dead angle is effectively avoided, and therefore the washing effect of the dish washing machine is guaranteed; meanwhile, washing water pressure is maintained, and the spraying hole can be effectively prevented from being clogged.

Description

technical field [0001] The invention relates to a dishwasher, and at the same time relates to a dishwasher spray device installed in the dishwasher, which belongs to the technical field of dishwasher manufacture. Background technique [0002] Dishwasher is a device that uses nozzles to spray high-pressure washing water to clean tableware. Dishwasher generally includes a dishwasher liner that forms a cleaning room. There is a tableware input port in front of the liner, and a door is set at the tableware input port. , There are tableware racks, showers, etc. in the cleaning room. [0003] The existing static shower installed in the dishwasher is generally realized by opening a spray hole on the shower. In order to avoid washing dead ends, the shower with this structure can only be used by reducing the aperture of the spray hole. It can be realized by increasing the spray pressure, or by increasing the number of spray holes. However, if the aperture is too small, it is easy t...
