Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below by way of specific embodiments with reference to the accompanying drawings.

In the present embodiment, a middle spray structure is provided, as shown in fig. 2 to 6, a water outlet end 11 disposed on a water conduit 1 is butted with a water inlet end 3 disposed at one end of a spray arm 2; the utility model discloses a flexible hose 4, including the flexible hose 4, it can be followed to intake end 3, intake end 3 with be equipped with between the spray arm 2 and can follow the flexible hose 4 that the end 3 removed of intaking, wherein, flexible hose 4 is formed by the flexible material preparation, and is concrete, and flexible hose 4 is formed by the PVC preparation, and flexible hose 4 can also be formed by other flexible material preparations, such as TPV etc. this embodiment does not do the restriction to the preparation material of flexible hose 4, as long as can satisfy flexible hose 4 can follow the end 3 that intakes freely and remove can.

In the embodiment, the water outlet end 11 of the water conduit 1 is butted with the water inlet end 3 of the spray arm 2, so that the situation that the idle water inlet end 3 leaks water or pressure leaks due to the idle water inlet end 3 in the prior art is avoided; in addition, through the flexible hose 4 that sets up between end 3 and the spray arm 2 of intaking for after the gear of promotion dish washer, because flexible hose 4 is formed by flexible material preparation, have certain flexibility, can remove along with the end 3 of intaking, realized that the end 3 of intaking after promoting docks with play water end 11 freely, can not appear because the end 3 of intaking promotes along with the shelf and leads to intaking end 3 and play water end 11 dislocation, the unable condition of docks with play water end 11. The well spraying structure that this embodiment provided is simple, easily realizes, convenient operation, and with low costs.

As shown in fig. 2-3, the spray arm 2 includes a spray pipe 21 connected to the flexible hose 4, and a spray opening 211 is provided at an end of the spray pipe 21 away from the flexible hose 4. The washing water flows into the water inlet end 3 from the water outlet end 11 arranged on the water conduit 1, passes through the flexible hose 4 and the spray pipe 21 in sequence, and is finally sprayed out from the spray port 211.

As shown in fig. 2, the water inlet end 3 includes a clamping portion 31 having a trumpet-shaped structure, and a connecting pipe 32 connected to the flexible hose 4 and coaxially disposed with the clamping portion 31; the water conduit 1 is fixedly provided with a water outlet base 12, and the water outlet end 11 is arranged on the water outlet base 12; the end of the engaging portion 31 is pressed against the end of the water outlet base 12 facing the spray arm 2, and the water outlet end 11 extends into the connecting pipe 32. Wherein, the water outlet end 11 is provided with a sealing ring 7. When the spray arm 2 is used for spraying, the end face of the clamping part 31 is pressed against the water outlet base 12, the water outlet end 11 extends into the connecting pipe 32 and is sealed through the sealing ring 7, so that the good sealing performance of the spray arm 2 in the spraying process is ensured, and the water leakage and pressure leakage of the water outlet end 11 and the water inlet end 3 are avoided.

As shown in fig. 3, two sliders 311 are symmetrically disposed on two sides of the engaging portion 31, and a central connecting line of the two sliders 311 intersects with a central axis of the engaging portion 31; two U-shaped grooves 51 are symmetrically and fixedly arranged on the shelf at two sides of the water inlet end 3, and the two sliding blocks 311 respectively extend into the two U-shaped grooves 51 and can slide along the U-shaped grooves 51.

After the position of good shelf in the dish washer, correspondingly, set up in on the shelf U type groove 51's position is also just fixed, at this moment, the tip of block portion 31 support press in go out water base 12 orientation the one end of spray arm 2, it stretches into to go out water end 11 in the connecting pipe 32, the washing water that flows out by play water end 11 flows in spray arm 2 through intaking end 3, because the U type groove 51 rigidity of block portion 31 both sides and the slider 311 card that sets up on the block portion 31 go into in the U type groove 51, at this moment, the U type groove 51 of block portion 31 both sides plays limiting displacement to block portion 31, can prevent effectively that play water end 11 from taking place to remove or the condition of dislocation with intaking end 3 for the junction of play water end 11 and intaking end 3 is more firm, has further guaranteed the fastness of intaking end 3 and play water end 11 being connected, when having avoided spraying arm 2, intake end 3 with the condition that goes out water end 11 appears leaking or leaking takes place.

In addition, after the shelf is lifted, the clamping part 31 only needs to slide along the U-shaped groove 51 to a position in butt joint with the water outlet end 11, and meanwhile, the flexible hose 4 moves along with the clamping part 31, so that the water inlet end 3 and the water outlet end 11 can be in butt joint freely, and the butt joint convenience of the water inlet end 3 and the water outlet end 11 is guaranteed.

Wherein, fig. 4 is a schematic structural view of the water inlet end 3 facing the water outlet end 11, fig. 5 and fig. 6 are schematic structural views of the water outlet end 11 being higher and lower than the spray arm 2, respectively, the engaging portion 31 in fig. 5 and fig. 6 slides along the U-shaped groove 51 through the sliding block 311, and can be aligned with the water outlet end 11, once the rack is fixed in the dishwasher, the position of the U-shaped groove 51 is fixed, and the water inlet end 3 and the water outlet end 11 are conveniently aligned and centered.

The spray pipe 21 is provided with a plurality of hooks 6 for hanging the spray pipe on the shelf. Specifically, the above-mentioned couple 6 that this embodiment provided is L type structure, including the rigid coupling in vertical portion 61 on the shower 21, and hang and establish the horizontal part 62 of shelf, the unsettled setting of one end of horizontal part 62, the other end connect in vertical portion 61.

In addition, in order to facilitate hooking and detaching of the shower arm 2, preferably, the number of the hooks 6 provided in the present embodiment is two, and two of the horizontal portions 62 of the hooks 6 are provided with one ends facing each other in a suspended manner.

The embodiment also provides a dish washing machine, which comprises the middle spraying structure, so that the condition that water leakage or pressure leakage occurs to the idle water inlet end 3 due to the idle water inlet end 3 in the prior art is avoided; meanwhile, the water inlet end 3 after being lifted can be freely butted with the water outlet end 11.

It is noted that the foregoing illustrates and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined by the appended claims and their equivalents.
