With continued reference to fig. 10, in some examples, the first ball 613 is spherical, the first ball 613 is located at the connection between the first sub-channel 611 and the second sub-channel 612, and the first ball 613 is fixedly connected with the inner wall of the second sub-channel 612. I.e. the inner wall of the second sub-channel 612 is fixedly connected with the first ball 613 through a plurality of connecting posts.

With continued reference to fig. 10, in some examples, the first ball 613 is located in the middle of the second sub-channel 612. When the first ball 613 is located in the middle of the second sub-channel 612, the spray liquid flowing through the second sub-channel 612 can have a more even pressure rise, so as to avoid the centrifugal impact force of the spray liquid flowing through the first ball 613 on the first ball 613 and damage the connection relationship between the first ball 613 and the inner wall of the second sub-channel 612.

In some examples, the first ball 613 is closer to the water outlet of the second sub-channel 612, and at this time, the first ball 613 and the second sub-channel 612 further pressurize the spray liquid in the second sub-channel 612, so that the spray liquid is in a hollow column shape when being sprayed from the water outlet. Through hollow columnar spray liquid, compare solid columnar spray liquid, spray liquid's velocity of flow is faster, and impact force is bigger, and is better to the cleaning performance of tableware. Meanwhile, the inner wall of the tableware with a deeper inner cavity can be better rinsed.

In some examples, the first ball 613 may be replaced by a booster column, where the booster column is a cylinder, and the booster column through the cylinder may also play a role in improving the pressure and the flow rate of the spray liquid, so that the spray flushing effect of the spray liquid is better. Meanwhile, compared with the use of the first ball 613, the pressurizing column can be directly connected with the inner wall of the second sub-channel 612 through the two end surfaces of the column, so that the connection between the pressurizing column and the second sub-channel 612 is tighter.

In some examples, the first ball 613 may be a regular polyhedron, and the above-mentioned effect of increasing the hydraulic pressure of the spray liquid may be achieved by disposing the polyhedron in the second sub-channel 612. Alternatively, the first beads 613 may be irregular polyhedrons, and the effect of improving the hydraulic pressure of the shower liquid may be achieved by disposing the irregular polyhedrons in the second sub-passages 612.

Referring to fig. 11, on this basis, a second spray flow channel is provided inside the second spray head 62, the second spray flow channel includes a third sub-channel 621 and a fourth sub-channel 622, one end of the third sub-channel 621 is communicated with the liquid outlet 41, the other end of the third sub-channel 621 is communicated with one end of the fourth sub-channel 622, and the other end of the fourth sub-channel 622 is a water outlet hole of the second spray head 62; the aperture of the third sub-passage 621 gradually decreases in the direction of the flow of the spray liquid, and the aperture of the fourth sub-passage 622 gradually increases in the direction of the flow of the spray liquid. The third sub-channel 621 and the fourth sub-channel 622 in the fourth spray head are communicated, one end of the fourth sub-channel 622 is provided with a water outlet, namely, the spray liquid washes tableware on the shelf 2 through the fourth sub-channel 622, at the moment, the aperture of the third sub-channel 621 gradually decreases along the flow direction of the spray liquid, so that the flow speed of the spray liquid is accelerated when the spray liquid flows into the fourth sub-channel 622 from the water supply system 4, and the pressure of the spray liquid is increased when the spray liquid enters the fourth sub-channel 622; the aperture of the fourth sub-channel 622 gradually increases along the flow direction of the spray liquid, that is, the aperture of one side of the fourth spray channel, which is close to the water blowing port, gradually increases along the flow direction of the spray liquid, and although the flow rate of the spray liquid can be reduced to a certain extent, the spray liquid can extend outwards along the inner wall of the fourth sub-channel 622 and finally be sprayed out in a conical shape. The spray liquid at the pressure is sprayed out from the water outlet, so that a larger spray area can be formed on the shelf 2 by the conical spray liquid, and the tableware in the larger area can be cleaned in an enhanced manner.

In some examples, the second spray head 62 has two second spray liquid flow passages, and both the second spray liquid flow passages are communicated with the liquid outlet 41, and the other ends of both the second spray liquid flow passages are water outlets. In this way, two spray liquid columns for enhanced washing can be sprayed simultaneously on the second spray head 62, and two areas on the shelf 2 are simultaneously rinsed.

In some examples, the second spray head 62 has a plurality of second spray liquid flow passages, and the plurality of second spray liquid flow passages are all communicated with the liquid outlet 41, and the other ends of the plurality of second spray liquid flow passages are all water outlets. In this way, a plurality of spray liquid columns for enhanced cleaning can be sprayed simultaneously on the second spray head 62, and a plurality of areas on the shelf 2 can be simultaneously cleaned.

Referring to fig. 12, in some examples, the third sub-passage 621 includes multiple sections, and the multiple sections of the third sub-passage 621 include conditions of gradually decreasing, increasing and maintaining along the flow direction of the spray liquid, but the aperture of one end of the third sub-passage 621, which is in communication with the liquid outlet 41, is larger than the aperture of the other end. In this way, the difficulty of the production and processing of the third sub-channel 621 can be reduced, the third sub-channel 621 can adapt to more environments in the cleaning cavity, and the effect of improving the water pressure can be achieved.

In some examples, the third sub-passage 621 is sealingly connected to the liquid outlet 41 by a pipe joint. The sealing connection through the pipe joint can ensure the sealing shape and the connection strength between the third sub-channel 621 and the liquid outlet 41, and can ensure the connection strength between the liquid outlet 41 and the second nozzle 62 even under higher pressure.

In some examples, the third sub-channel 621 is fixedly connected to the liquid outlet 41 by gluing. By this connection, the third sub-passage 621 can be stably connected to the liquid outlet 41.

In some examples, the fourth sub-channel 622 is an integral channel with the third sub-channel 621. In this way the connection between the third sub-channel 621 and the fourth sub-channel 622 can be stabilized. The aperture of one side of the fourth spray channel close to the water blowing port is gradually increased along the flow direction of the spray liquid.

In some examples, the other end outlet of the fourth sub-channel 622 is directed towards the shelf 2. The outlet of the fourth sub-channel 622 faces the shelf 2, so that spraying liquid sprayed from the fourth sub-channel 622 can flush tableware on the shelf 2 in a deeper level, and meanwhile, as the aperture of the fourth sub-channel 622 is gradually increased along the flowing direction of the spraying liquid, the sprayed liquid column is in a hollow cone shape, and the flushing area can be increased.

In some examples, the gradually increasing aperture along the flow direction of the spray liquid may be adjusted to form a chamfer at the water outlet of the fourth sub-channel 622, and the purpose of tapering the sprayed spray liquid in the fourth sub-channel 622 may be achieved by forming a chamfer at the outlet of the fourth sub-channel 622.

Referring to fig. 13, the second nozzle 62 further includes a second ball 623, and the second ball 623 is disposed in the fourth sub-channel 622. The ball is arranged in the fourth sub-channel 622, so that the flow area of the spray liquid in the fourth sub-channel 622 can be locally reduced, the flow rate of the spray liquid can be further improved, the conical spray liquid sprayed from the water outlet has higher impact force, and the tableware can be better washed when the reinforced washing area of the spray liquid on the shelf 2 is increased.

Referring to fig. 13, in some examples, the second ball 623 is spherical, the second ball 623 is located at the junction of the third sub-channel 621 and the fourth sub-channel 622, and the second ball 623 is fixedly connected to the inner wall of the fourth sub-channel 622. I.e., the inner wall of the fourth sub-channel 622 and the second beads 623 are fixedly coupled by a plurality of coupling posts.

Referring to fig. 13, in some examples, a second ball 623 is located in the middle of the fourth sub-channel 622. When the second ball 623 is located in the middle of the fourth sub-channel 622, the spray flowing through the fourth sub-channel 622 can have a more even pressure rise, so as to avoid the centrifugal impact force of the spray flowing through the second ball 623 on the second ball 623 and destroy the connection relationship between the second ball 623 and the inner wall of the fourth sub-channel 622.

In some examples, the second ball 623 is closer to the outlet hole of the fourth sub-channel 622, and at this time, the second ball 623 and the fourth sub-channel 622 further pressurize the spray liquid in the fourth sub-channel 622, so that the spray liquid is in a hollow column shape when being ejected from the outlet hole. Through hollow columnar spray liquid, compare solid columnar spray liquid, spray liquid's velocity of flow is faster, and impact force is bigger, and is better to the cleaning performance of tableware. Meanwhile, the inner wall of the tableware with a deeper inner cavity can be better rinsed.

In some examples, the second ball 623 may also be replaced with a booster column, where the booster column is a cylinder, and the booster column through the cylinder may also play a role in improving the pressure and flow rate of the spray liquid, so that the spray flushing effect of the spray liquid is better. Meanwhile, the pressurizing column may be directly connected with the inner wall of the fourth sub-channel 622 through both end surfaces of the column, so that the connection between the pressurizing column and the fourth sub-channel 622 is tighter, compared to the use of the second ball 623.

In some examples, the second beads 623 may also be regular polyhedrons, and the above-described effect of increasing the spray liquid pressure may be achieved by disposing the polyhedrons in the fourth sub-channel 622. Alternatively, the second beads 623 may be irregular polyhedrons, and the effect of increasing the liquid pressure of the spray liquid may be achieved by disposing the irregular polyhedrons in the fourth sub-passage 622.

Referring to fig. 14, in some examples, since the aperture gradually increases in the direction of flow of the spray liquid, a side wall of the fourth sub-passage 622 near the water outlet may be provided in a tapered shape having an increased diameter in the direction of flow of the spray liquid, and the second beads 623 may be replaced with the pressurizing cone 624. The outer ring surface of the pressurizing cone 624 may be parallel to the inner wall of the fourth sub-channel 622, or may be non-parallel to the inner wall of the fourth sub-channel 622, so as to achieve a corresponding pressurizing effect.

The first shower nozzles 61 and the second shower nozzles 62 can further improve the increase of areas with different flushing effects, so that the rack 2 is provided with a plurality of tableware flushing areas respectively matched with the first shower nozzles 61 and the second shower nozzles 62, and then the tableware difficult to be flushed can be cleaned efficiently and cleanly, and the cleaning efficiency of the dish washing machine is improved.

With continued reference to fig. 15, in some examples, the dishwasher includes a plurality of first spray heads 61 and a second spray head 62. The dishwasher may also comprise a plurality of second spray heads 62 and a first spray head 61. Through the two setting modes, the effect of strengthening washing can be achieved, and the scope of strengthening washing can be defined at the same time, namely, the bowl with a large inner cavity is strengthened and washed through the first spray nozzle 61, and the cup with a deep inner cavity is strengthened and washed through the second spray nozzle 62. The number of the first spray heads 61 and the second spray heads 62 is limited, so that the dishwasher can have different washing efficiencies for different tableware, and the selection is convenient for consumers.

In some examples, the number of first nozzles 61 and second nozzles 62 may or may not be uniform. The number of the first spray heads 61 and the second spray heads 62 is limited, so that the dish-washing machine has different washing efficiencies for different dishes, and a consumer can select the type of dish-washing machine needed by the consumer in a targeted manner.

Referring to fig. 16, the dishwasher further includes a connection pipe 63, the reinforcing shower nozzle 6 is connected to the liquid outlet 41 through the connection pipe 63, and the connection pipe 63 is a flexible pipe. When the reinforced shower nozzle 6 is connected with the liquid outlet 41 through the flexible pipeline, the position of the reinforced shower nozzle 6 can be manually adjusted so as to change the area on the shelf 2 needing reinforced spraying, thereby being convenient for placing and cleaning tableware.

In some examples, when the connection pipeline 63 of the dishwasher is a flexible pipeline, in order to make the spraying effect of the enhanced shower nozzle 6 more stable, a mounting block may be provided on the liner 1, and the enhanced shower nozzle 6 may be detachably provided on the mounting block by means of a clamping connection or a bolting connection, so as to ensure the stability in normal use. A plurality of mounting blocks may be provided in the liner 1 to facilitate adjustment of the position of the reinforcing washer nozzle 6, so that adjustment of the reinforcing washer area of the reinforcing washer nozzle 6 is facilitated.

In some examples, the flexible tubing may be flexible tubing or bellows, which may achieve the above-described effect of facilitating adjustment of the position of the flexible tubing.

In some examples, connecting tubing 63 is a rigid tubing, such as a rigid metal tubing or PVB tubing. The reinforcing shower nozzle 6 can be conveniently fixed in such a way, and the reinforcing shower nozzle 6 is convenient to stabilize in working. Meanwhile, the strength of the hard pipeline is higher when the hard pipeline is used, so that the transportation of the spraying liquid is more stable.

Referring to fig. 17, on this basis, the shelf 2 is provided with multiple layers, the multiple layers of shelf 2 includes a main shelf 23 and multiple layers of shelves 22, the spray arms 3 are provided with multiple layers, the main shelf 23 and multiple secondary shelves 22 are in one-to-one correspondence with the spray arms 3, and all the spray arms 3 are independently communicated with the liquid outlet 41; the lower parts of the main shelf 23 and each layer of shelf 22 are provided with reinforced washing spray heads 6, and all the reinforced washing spray heads 6 are independently communicated with the liquid outlet 41; the water supply system 4 comprises a main water supply system and a spray arm 3 bracket, wherein liquid outlets 41 are formed in the main water supply system and the spray arm 3 bracket, the reinforced shower nozzle 6 and the spray arm 3 bracket corresponding to the main shelf 23 are communicated with the liquid outlets 41 of the main water supply system, and the reinforced shower nozzle 6 and the spray arm 3 bracket corresponding to the secondary shelf 22 are communicated with the liquid outlets 41 of the spray arm 3 bracket. When the shelf 2 has multiple layers, the tableware to be cleaned can be placed on each layer of shelf 2, so that the dish-washing machine can clean more tableware at the same time, and the working efficiency of the dish-washing machine is further improved.

Referring to fig. 18, on this basis, the number of the shelves 2 is three, the number of the spray arms 3 is three, and the three shelves 2 and the three spray arms 3 are in one-to-one correspondence and are arranged below each shelf 2. In this way, it is possible to place dishes on each layer of racks 2, while washing more dishes. At this time, since there is one water supply system 4, there are two or three spray arms 3 far from the liquid outlet 41 of the water supply system 4, and for convenience of spray liquid delivery, the support of the spray arm 3 for delivering spray liquid can be increased to rotatably mount each spray arm 3 and provide spray liquid for the spray arm 3.

In some examples, the three spray arms 3 are all connected to the same outlet 41 of the water supply 4, and the enhanced shower head 6 is also connected to the same outlet 41. In this connection mode, in order to make the water pressure at the water supply system 4 and the outlet 41 where each spray arm 3 and the enhanced shower nozzle 6 are communicated with the water supply system 4 be the same, a water dividing valve can be added in the water supply system 4, and the hydraulic pressure of each split flow in the water supply system 4 is regulated through the water dividing valve, so that the hydraulic pressures are the same or stable in proportion, and a better effect of cleaning tableware is achieved.
