[0021] Example 1

[0022] Combined with Figure 1-5 The present embodiment provides a spray device, including a spray seat 10, a rotating transmission member 11 and a soft sealing member 12; a mounting hole 100 is provided on the spray seat 10, and the rotating transmission member 11 is movably matched with the mounting hole 100; a portion of the rotating transmission member 11 located in the mounting hole 100 is circumferentially provided with a groove 110, and the soft sealing member 12 includes an annular body 120 and a lip 121 connected to each other, the annular body 120 is embedded in the groove 110, and the lip 121 extends outward from the connection with the annular body 120, the outer diameter of the lip 121 is larger than the outer diameter of the annular body 120, and the outer wall of the lip 121 abuts against the inner wall of the mounting hole 100.

[0023] A spray device of this embodiment is used as the transmission part of the spray arm, wherein the rotating transmission member 11 is installed in the mounting hole 100 of the spray seat 10 and can rotate in the mounting hole 100. The rotating transmission member 11 is used to transmit power, thereby driving the movement of mechanisms such as the spray arm in the spray system.

[0024] Combined with Figure 1 In some embodiments, the spray seat 10 includes a base 101 and an upper cover 102, at least two rotating transmission members 11 are provided, and the rotating transmission members 11 are transmission-connected to each other, and the mounting holes 100 are provided on the base 101, and the number of the mounting holes 100 and the soft sealing member 12 is consistent with the number of the rotating transmission members 11. The rotating transmission member 11 can be a mechanism that realizes transmission through its own rotation, such as a gear, a sprocket, a pulley, or a worm gear, and the power of a driving device such as a motor can be transmitted to the spray arm through the rotating transmission member 11.

[0025] When the dishwasher is working normally, water may penetrate into the spray seat 10 from the gap between the rotating transmission member 11 and the mounting hole 100. In order to solve this technical problem, that is, to prevent water from entering the gap between the rotating transmission member 11 and the mounting hole 100, in this embodiment, a soft seal 12 is provided at the gap.

[0026] Combined with Figure 2 , 3 5. The soft seal 12 includes an annular body 120 and a lip 121 connected to each other, wherein the annular body 120 is embedded in a slot 110 arranged circumferentially on the outer side of the rotating transmission member 11 to achieve a fixed connection between the soft seal 12 and the rotating transmission member 11. Also, the lip 121 of the soft seal 12 extends outward from the connection with the annular body 120, and the outer diameter of the lip 121 is greater than the outer diameter of the annular body 120. After the soft seal 12 is installed, the outer wall of the lip 121 abuts against the inner wall of the mounting hole 100, thereby fully closing the gap between the rotating transmission member 11 and the mounting hole 100 to achieve a sealing effect.

[0027] And, in a more preferred embodiment, the lip 121 is interference fit with the inner wall of the mounting hole 100, thereby ensuring that the gap is fully filled, thereby ensuring a better sealing effect.

[0028] It should be noted that the spray device proposed in this embodiment is mainly used in an electric spray system, and uses a motor as power input, the power provided is rated, and because the contact area and pressure between the soft seal 12 and the inner wall of the mounting hole 100 are limited, the friction force generated is also limited. Therefore, the friction between the soft seal 12 and the inner wall of the mounting hole 100 will not affect the rotation of the rotating transmission part 11.

[0029] For the soft sealing member 12 of this embodiment, the annular body 120 and the lip 121 are preferably integrally formed, and the material can be soft plastic or rubber, such as soft PVC, silicone rubber, nitrile rubber, etc.

[0030] Combined with Figure 3 In one embodiment, the lip 121 is tilted outward relative to the axial centerline a, and a pressure bearing surface 122 is provided on the side of the lip 121 facing the centerline a. The pressure bearing surface 122 in this embodiment is used to withstand the pressure of the water flow. Since the lip 121 is tilted outward relative to the axial centerline a, when the water flow applies pressure to the pressure bearing surface 122, the lip 121 will be subjected to the pressure provided by the incoming water. The greater the water pressure, the greater the force on the lip 121. The lip 121 will be deformed due to the force, but the lateral space of the gap between the rotating transmission member 11 and the mounting hole 100 remains fixed. Therefore, this deformation will increase the interference between the lip 121 and the inner wall of the mounting hole 100, further improving the sealing effect, and the sealing effect can be improved as the water pressure increases.

[0031] In combination with the aforementioned sealing principle, it can be known that the lip 121 needs to deform and swing to enhance the sealing effect. Therefore, in a further embodiment, the lip 121 is further improved, and the thickness of the lip 121 gradually decreases from the connection with the annular body 120 to the outside, thereby, on the one hand, the connection strength of the connection between the lip 121 and the annular body 120 can be ensured, and at the same time, the lip 121 at the edge is thinner and can be more easily deformed, thereby achieving the above-mentioned enhanced sealing effect.

[0032] Based on the above description, it can be known that the annular body 120 is embedded in the slot 110 arranged circumferentially on the outer side of the rotating transmission member 11 to achieve a fixed connection between the soft seal 12 and the rotating transmission member 11. In order to ensure the assembly strength between the soft seal 12 and the slot 110, in one embodiment, the depth of the annular body 120 embedded in the slot 110 is greater than the thickness of the annular body 120. This embodiment can ensure that the annular body 120 can still be firmly stuck in the slot 110 under high water pressure, thereby ensuring that the soft seal 12 will not be separated from the rotating transmission member 11.

[0033] In combination with the above description, in order to solve the technical problem of poor sealing of the dishwasher spray system, the spray device and the dishwasher of this embodiment set the soft seal 12 between the spray seat 10 and the rotating transmission member 11 through the slot 110. When the water flows in from the lower side of the spray seat 10, it is blocked by the lip 121 and the water flow will not continue to flow into the interior of the spray seat 10. Therefore, the incoming water will all enter the spray arm, thereby reducing water pressure leakage and achieving a sealing and pressurizing effect.

Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
