The present disclosure mainly provides a spray washer, which is mainly applied to a dish-washing machine, to increase the utilization of water and the tableware cleaning efficiency of the dish-washing machine.
The structure of the spray washer will be mainly described below.
Referring to
at least one spraying pipe 100, the spraying pipe 100 being provided with at least one water injection nozzle;
a transmission mechanism including a driving gear 310 and a driven gear 320 meshing with the driving gear 310, the driven gear 320 being connected to the spraying pipe 100 to drive the spraying pipe 100 into rotation; and
a driving mechanism 200 connected to the driving gear 310 to drive the driving gear 310 into rotation.
In this embodiment, the spraying pipe 100 is configured as a columnar pipe. The spraying pipe includes a water inlet end 110 and a driving end 120. That is, the water inlet structure of the spraying pipe 100 is provided at one end of the spraying pipe 100 and the driving structure of the spraying pipe 100 is provided at another end of the spraying pipe 100, so that the driving structure and the water inlet structure do not interfere with each other. Of course, in some embodiments, in order to save space, the driving structure and the water inlet structure may also be provided at the same end of the spraying pipe 100. The driving end 120 of the spraying pipe 100 is closed, and the water is discharged from the water injection nozzle after the water enters from the water inlet end 110. The water injection nozzle is provided on the pipe wall of the spraying pipe 100, so that the water flow may be directly sprayed from the water injection nozzle. In one embodiment, a sprinkler may also be installed in the water injection nozzle, so that the water may be sprayed from the sprinkler.
The driven gear 320 may be directly provided around the driving end 120. Of course, in some embodiments, a driven shaft can be provided on the driving end, and the driven gear 320 is provided around the driven shaft. The axis of rotation of the driven gear 320 is collinear with the axial axis of the spraying pipe 100. The driving gear 310 meshes with the driven gear 320. There may be a plurality of positions of the driving gear with respect to the driven gear 320, such as, above, below, at the left side, or at the right side. The position that the driving gear is located below the driven gear 320 is taken as an example. Taking an upward spraying direction as an example, the driving gear 310 is arranged below the driven gear to avoid affecting the cleaning of the tableware. Herein, the driving gear 310 and the driven gear 320 are both spur gears.
There are many forms of driving structures, such as motors, impellers, fuel engines, etc. The driving mechanism 200 has a driving shaft. The driving shaft is directly inserted into the driving gear 310, or connected to the driving gear 310 after being decelerated by the transmission structure 300. The driving gear 310 rotates through the driving shaft as a rotating shaft. The driving mechanism 200 takes a driving motor as an example, the driving gear 310 is fixedly connected to the rotating shaft of the driving motor.
In this embodiment, the driving force of the driving mechanism 200 is transmitted to the spraying pipe 100 through the driving gear 310 and the driven gear 320, so that the spraying pipe 100 rotates along an axial axis thereof, and water is sprayed from the water injection nozzle on the spraying pipe 100. During the rotation of the spraying pipe 100, a spray washing area is formed. Since the spraying pipe 100 is driven by a gear structure, both the rotation of the spraying pipe 100 and the transmission of power are very stable and reliable. Meanwhile, the rotation angle of the spraying pipe 100 can be accurately controlled, to control the change of the spray washing area, so that the spray washer can accurately control the spraying area, which facilitates improving the accuracy of the spray washer for spray washing the tableware, and increasing the utilization of water and cleaning efficiency.
It should be noted that, in order to ensure the range of the water feeding area, the rotation angle α of the spraying pipe 100 is from 100° to 150°, taking from 120° to 140° as an example. By setting the rotation angle of the spraying pipe 100 as a range from 100° to 150°, it can avoid that if the angle is too large, the spraying pressure is not enough to clean; if the angle is too small, the area covered by the spraying pipe 100 is too small to cover the entire area required for cleaning.
In order to improve the driving efficiency of the driving structure, the spray washer includes a plurality of spraying pipes 100. The spray washer further includes a first transmission wheel 610 and a first linkage 620. One end of one of the spraying pipes 100 is connected to the first transmission wheel 610, and another end of the spraying pipe is in communication with a water source. One end of the first linkage 620 is hinged to the driven gear 320, and another end of the first linkage is hinged to the first transmission wheel 610, to drive the spraying pipe 100 and the first transmission wheel into rotation with rotation of the driven gear 320.
In this embodiment, the spraying pipes 100 may be positioned at the front side, the rear side or on the top of the spraying pipe 100 connected to the driven gear 320. In some embodiments, the spray washer includes a plurality of first linkages 620 and a plurality of first transmission wheels 610 connected to the first linkages 620. In this case, one driven gear 320 may simultaneously drive the plurality of first transmission wheel 610, to simultaneously drive the plurality of spraying pipes 100. One first transmission linkage and one first transmission wheel 610 are described in detail below.
One end of the first linkage 620 is hinged to the driven gear 320, so that the first linkage 620 rotates with the rotation of the driven gear 320. Another end of the first linkage 620 is hinged to the first transmission wheel 610, so that the first linkage 620 transmits the rotation displacement of the driven gear 320 to the first transmission wheel 610, the first transmission wheel 610 converts the displacement of the first linkage 620 into the rotation displacement, and finally transmits the rotation displacement to the spraying pipes 100. As a result, the spraying pipes 100 rotate with rotation of the driven gear 320.
In some embodiments, in order to better drive the spraying pipes 100, one of the spraying pipes 100 is connected to a middle portion of the first transmission wheel 610. One end of the first linkage 620 is connected to an upper portion or a lower portion of the first transmission wheel 610, and another end of the first linkage is connected to an upper portion or a lower portion of the driven gear 320. Herein, the connection between the spraying pipe 100 and the first transmission wheel 610 is similar to the connection between the driven gear 320 and the spraying pipe 100. The axis of rotation of the first transmission wheel is collinear with the axis of rotation of the spraying pipe 100. One end of the first linkage 620 is hinged to the top of the first transmission wheel 610, and another end of the first linkage is hinged to the top of the driven gear 320. In this case, the rotation direction of the first transmission wheel 610 is the same as the rotation direction of the driven gear 320. When one end of the first linkage 620 is hinged to the bottom of the first transmission wheel 610, and another end of the first linkage is hinged to the top of the driven gear 320, the rotation direction of the first transmission wheel 610 is opposite to the rotation direction of the driven gear 320.
In order to further increase the driving efficiency of the driving mechanism, the spray washer further includes a second transmission wheel 710 and a second linkage 720. One end of one of the spraying pipes 100 is connected to the second transmission wheel 720, and another end of the spraying pipe is in communication with the water source. One end of the second linkage 720 is hinged to the first transmission wheel 610, and another end of the second linkage is hinged to the second transmission wheel 710, to drive the spraying pipe 100 and the second transmission wheel into rotation with the rotation of the first transmission wheel.
In this embodiment, the second transmission wheel 710 is located on the top of the first transmission wheel 610, or at a side of the first transmission wheel away from the driven gear 320. The spray washer includes a plurality of second transmission wheels 710 and a plurality of second linkages 720. In this case, one first transmission wheel 610 may simultaneously drive the plurality of second transmission wheels 710. One second transmission linkage and one second transmission wheel 710 are described in detail below.
One end of the second linkage 720 is hinged to the first transmission wheel 610, so that the second linkage 720 rotates with the rotation of the first transmission wheel 610. Another end of the second linkage 720 is hinged to the second transmission wheel 710, so that the second linkage 720 transmits the rotation displacement of the first transmission wheel 610 to the second transmission wheel 710, the second transmission wheel 710 converts the displacement of the second linkage 720 into the rotation displacement, and finally transmits the rotation displacement to the spraying pipes 100. As a result, the spraying pipes 100 rotate with rotation of the first transmission wheel 610.
In some embodiments, in order to better drive the spraying pipes 100, the spraying pipe 100 is connected to a middle portion of the second transmission wheel 710. One end of the second linkage 720 is connected to an upper portion or a lower portion of the first transmission wheel 610, and another end of the second linkage is connected to an upper portion or a lower portion of the second transmission wheel.
Herein, the connection between the spraying pipe 100 and the second transmission wheel 710 is similar to the connection between the first transmission wheel 610 and the spraying pipe 100. The axis of rotation of the second transmission wheel 710 is collinear with the axis of rotation of the spraying pipe 100. One end of the second linkage 720 is hinged to the top of the second transmission wheel 710, and another end of the second linkage is hinged to the top of the first transmission wheel 610. In this case, the rotation direction of the second transmission wheel 710 is the same as the rotation direction of the first transmission wheel 610. When one end of the second linkage 720 is hinged to the bottom of the second transmission wheel 710, and another end of the second linkage is hinged to the top of the first transmission wheel 610, the rotation direction of the second transmission wheel 710 is opposite to the rotation direction of the first transmission wheel 610.
In order to supply sufficient water to the spraying pipes 100, the spray washer includes a water supply assembly. The water supply assembly includes a water pump 400, a water feeding pipe 510 and a plurality of water distributing pipes 520. One end of the water feeding pipe 510 is in communication with the water pump 400, and another end of the water feeding pipe is in communication with water distributing pipes 520. One end of each water distributing pipe 520 away from the water feeding pipe 510 is in communication with one of the spraying pipes 100. One end of the water feeding pipe 510 is in communication with the water pump 400, and another end of the water feeding pipe is in communication with the water distributing pipes 520. The water pump 400 pumps water from the water source to the water feeding pipe 510, and then the water feeding pipe 510 delivers water to the water distributing pipes 520. One end of each water distributing pipe 520 away from the water feeding pipe 510 is in communication with one of the spraying pipes 100. There are many ways of communication, such as surrounding, adapting through adapters, etc.
Herein, the water supply assembly is located below the spraying pipes 100, and each water distributing pipe 520 is arranged around the water feeding pipe 510 after being bent. When the spraying pipes 100 spray water upwardly, the water supply assembly below does not affect the spray washing of the spraying pipes 100, which ensures the effect of spray washing while fully utilizing the space.
In some embodiments, in order to improve the installation stability of the water feeding assembly and reduce the vibration noise, the spray washer further includes a reinforcing plate 530. The reinforcing plate 530 is connected to the water distributing pipes 520 along an arrangement direction of the water distributing pipes 520, and is provided with a fixing portion for fixing the reinforcing plate 530. The reinforcing plate 530 is fixedly connected to the inner container, so that the reinforcing plate 530 not only strengthens the strength and stability of the water distributing pipes 520, but also prevents the water distributing pipes 520 from swinging and vibrating greatly due to the impact of water flow by fixing the water distributing pipes 520, and effectively reducing the noise generated by the swinging and vibrating of the water distributing pipes 520.
The present disclosure further provides a dish-washing machine. The dish-washing machine includes an inner container and a spray washer. The structure of the spray washer refers to the above embodiments. Since the dish-washing machine adopts all of the above embodiments, the dish-washing machine at least has all the beneficial effects brought by the above embodiments, which is not repeated here. Herein, the inner container has a receiving chamber, within which the spray washer is arranged.
In order to improve the spray washing efficiency and effect of the spraying pipes 100, the dish-washing machine includes a bowl basket arranged within the inner container. Each spraying pipe 100 is provided with a plurality of water injection nozzles, which are arranged along a length direction of each spraying pipe 100 corresponding to a position of the bowl basket. The water injection nozzles are arranged corresponding to the bowl basket, so that the water flow sprayed from the water injection nozzles can be accurately sprayed onto the bowl basket, to improve the efficiency of cleaning the tableware in the bowl basket.
