Description

Technical Field

[0001] This invention relates to the field of dishwasher technology, and more particularly to a sprayer mounting structure and a dishwasher. Background Technology

[0002] There are two types of spray nozzles in current household dishwashers: one type is driven by water pressure, and the other type is driven by a motor. When the spray nozzle is driven by a motor, the motor occupies a certain amount of space, which reduces the interior space. To maximize the interior space, most current dishwashers use water pressure to drive the spray nozzle.

[0003] Although using water pressure to rotate the sprayer saves space compared to using a motor, for smaller dishwashers, the sprayer mounting components include two long clips, which take up a lot of space inside the tub during installation. In addition, the exposed clips make the sprayer look unsightly after installation.

[0004] Therefore, there is a need to propose a sprayer that can solve the problems of the existing sprayer's installation structure occupying the inner tank space and the installation structure being exposed and unsightly. Summary of the Invention

[0005] The purpose of this invention is to provide a sprayer installation structure and a dishwasher, which allows the sprayer installation structure to not occupy the space inside the inner tank after installation, and the installation structure does not leak after installation.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A sprayer mounting structure is provided, including a mounting ring disposed on an inner tank and a sprayer base disposed on the sprayer; the sprayer base includes a water inlet ring fixedly disposed on the sprayer and a connecting arm disposed outside the water inlet ring that can elastically deform, the fixed end of the connecting arm being fixedly connected to the sprayer, the water inlet ring communicating with the water outlet of the inner tank, and the connecting arm being able to be inserted into the mounting ring and rotate around its own axis within the mounting ring.

[0008] Preferably, a limiting ring is provided on the inner sidewall of the mounting ring, and a buckle is provided at one end of the connecting arm that extends into the mounting ring. The connecting arm in the elastically compressed state can pass through the limiting ring, and the limiting ring can lock the buckle in the free state into the mounting ring.

[0009] Preferably, the plurality of connecting arms are circumferentially arranged on the outside of the water inlet ring.

[0010] Preferably, the multiple connecting arms are circumferentially distributed on the outside of the water inlet ring.

[0011] As a preferred option, an arc-shaped water baffle is also provided between two adjacent connecting arms.

[0012] Preferably, the arc-shaped baffle plate is coaxially arranged with the water inlet ring.

[0013] Preferably, the fixed end of the connecting arm is fixedly connected to the arc-shaped baffle.

[0014] Preferably, the outer wall of the arc-shaped baffle is provided with at least one water-blocking ring, and the water-blocking ring is located at the end of the arc-shaped baffle that is closer to the sprayer.

[0015] Preferably, the sprayer base includes a water inlet ring and a connecting ring disposed outside the water inlet ring and coaxial with the water inlet ring. A limiting protrusion is provided on the outer wall of the connecting ring, and a limiting ring is provided on the inner wall of the mounting ring. The limiting protrusion engages with the limiting ring.

[0016] The present invention also provides a dishwasher, including the sprayer mounting structure described above.

[0017] Beneficial effects of this invention:

[0018] In this invention, the connecting arm is directly inserted into the mounting ring and can rotate around its own axis within the mounting ring. Compared to existing sprayer installation methods, this effectively reduces the fixed height of the sprayer, thereby saving installation space, especially for smaller inner tanks, allowing for greater usable space without increasing the inner tank's dimensions. Furthermore, because the fixed end of the connecting arm is fixedly connected to the sprayer, the water inlet ring directly communicates with the inner tank's outlet. Since the connecting arm and mounting ring are inserted into each other, the connecting arm is concealed by the mounting ring, preventing the connection structure between the sprayer and the inner tank from being exposed, resulting in a more aesthetically pleasing connection.

[0019] The dishwasher's sprayer and inner tub are installed using the aforementioned sprayer mounting structure. After installation, the mounting structure is not exposed. Compared to the existing technology that uses a pipe joint on the bottom surface of the inner tub chamber, this effectively reduces the fixed height of the sprayer, thus saving installation space. The connecting arm and mounting ring are directly snapped on, which effectively reduces the load on the sprayer compared to the separate snap-on structure in the existing design. Under the same water pressure conditions, the sprayer rotates faster, improving the spraying effect. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] This embodiment provides a sprayer installation structure. After installation, the sprayer installation structure occupies less space inside the inner tank 100, and the installation components are not exposed, making the sprayer 200 more aesthetically pleasing.

[0034] like Figure 1-2 As shown, the sprayer mounting structure specifically includes a mounting ring 1 disposed on the inner tank 100 and a sprayer base 2 disposed on the sprayer 200, wherein the sprayer base 2 can extend into the mounting ring 1 and be inserted and fixed to the mounting ring 1. The sprayer base 2 includes a water inlet ring 21 fixedly disposed on the sprayer 200 and a connecting arm 22 disposed outside the water inlet ring 21 that can elastically deform; wherein, the fixed end of the connecting arm 22 is fixedly connected to the sprayer 200, that is, in this embodiment, the connecting arm 22 and the water inlet ring 21 are non-contact, while the water inlet ring 21 is connected to the water outlet 101 of the inner tank 100 to allow washing water to enter the sprayer 200 to achieve the purpose of washing dishes, and the connecting arm 22 can be inserted into the mounting ring 1 and rotate around its own axis within the mounting ring 1.

[0035] In this embodiment, the connecting arm 22 is directly inserted into the mounting ring 1 and can rotate around its own axis within the mounting ring 1. Compared with the existing installation method of the sprayer 200, this effectively reduces the fixed height of the sprayer 200, thereby saving installation space. Especially for the inner tank 100 with its smaller space, this method allows the inner tank 100 to maintain a larger usable space without increasing its size. Furthermore, because the fixed end of the connecting arm 22 is fixedly connected to the sprayer 200, the water inlet ring 21 is directly connected to the water outlet 101 of the inner tank 100. Since the connecting arm 22 and the mounting ring 1 are connected by an insert, the connecting arm 22 is inserted into the mounting ring 1 and concealed by the mounting ring 1, thus preventing the connection structure between the sprayer 200 and the inner tank 100 from being exposed, making the connection more aesthetically pleasing.

[0036] Specifically, a limiting ring 11 is provided on the inner wall of the mounting ring 1, and a buckle 221 is provided at the end of the connecting arm 22 that extends into the mounting ring 1. The connecting arm 22, in its elastically compressed state, can pass through the limiting ring 11, and the limiting ring 11 can engage the buckle 221 in its free state within the mounting ring 1, thus limiting the sprayer 200 along the axial direction of the mounting ring 1. The limiting ring 11 has an isosceles trapezoidal cross-section, with the smaller base of the isosceles trapezoid facing the center of the limiting ring 11. This arrangement allows the buckle 221 to be guided by the two sides of the isosceles trapezoid when passing through the limiting ring 11, facilitating the engagement and disengagement of the limiting ring 11 and the buckle 221. It should be noted that both sides of the connection point between the buckle 221 and the limiting ring 11 are inclined sidewalls; this arrangement is also for the purpose of facilitating the engagement and disengagement of the limiting ring 11 and the buckle 221.

[0037] Since the snap-fit ​​structure consisting of the snap-fit ​​221 and the limiting ring 11 is located inside the mounting ring 1, in addition to making the sprayer 200 more aesthetically pleasing, it also prevents the sprayer mounting structure from being contaminated with washing liquid or dirt when the dishwasher is working, avoiding the harm of corrosion and increasing the service life of the mounting structure.

[0038] Since the connecting arm 22 is engaged with the mounting ring 1 in this embodiment to fix the spray arm, in order to fix the spray arm well, multiple connecting arms 22 are arranged circumferentially on the outside of the water inlet ring 21. In order to make the spray arm base rotate evenly when impacted by water flow, multiple connecting arms 22 should be evenly distributed circumferentially on the outside of the water inlet ring 21.

[0039] like Figure 3-4As shown, since water may leak from the gap between the connecting arm 22 and the limiting ring 11 after they are connected, an arc-shaped baffle 23 is provided between adjacent connecting arms 22 to solve this problem. To reduce the space occupied by the connecting arm 22 and the arc-shaped baffle 23, the arc-shaped baffle 23 is coaxially arranged with the water inlet ring 21. The fixed end of the connecting arm 22 is fixedly connected to the arc-shaped baffle 23 as a single unit. This structure reduces the length of the connecting arm 22, making it less prone to deformation when impacted by water flow, thus preventing the connecting arm 22 from easily detaching from the limiting ring 11. The height of the arc-shaped baffle 23 is less than the height of the connecting arm 22, ensuring an effective connection between the connecting arm 22 and the mounting ring 1.

[0040] like Figure 4 As shown, at least one water-blocking ring 231 is provided on the outer wall of the arc-shaped water-blocking plate 23. In this embodiment, there is one water-blocking ring 231, which is located at the end of the arc-shaped water-blocking plate 23 closest to the sprayer 200. That is, the water-blocking ring 231 is also located on the fixed end of the connecting arm 22. Since the arc-shaped water-blocking plate 23 is connected to the fixed end of the connecting arm 22, the water-blocking ring 231 is also located on the fixed end of the connecting arm 22. The above-mentioned water-blocking ring 231 plays a limiting role in the insertion of the connecting arm 22 into the mounting ring 1, preventing the sprayer 200 from shaking and becoming unstable during operation due to a large gap between the sprayer 200 and the mounting ring 1, thus affecting the spraying operation of the sprayer 200.

[0041] When water leaks between the inlet ring 21 and the outlet 101 of the inner tank 100, the leaking water is blocked by the arc-shaped baffle 23 and the baffle ring 231, filling the space formed by the inlet ring 21, the mounting ring 1, and the baffle ring 231, and will not flow out of the space. Since the space cannot be filled with water again, and the water flows back into the inlet ring 21 due to gravity, the problem of water leakage at the connection between the existing sprayer 200 and the inner tank 100 is solved. Because the space formed by the inlet ring 21, the mounting ring 1, and the baffle ring 231 is small enough, this arrangement can reduce the amount of water entering the space. Due to the reduction in the amount of water, the resistance encountered by the sprayer 200 when rotating is also reduced, and it rotates faster, effectively providing a spraying effect.

[0042] It should be noted that the water inlet ring 21, connecting arm 22, and arc-shaped water-blocking ring 231 are integrally formed with the sprayer 200. This structure reduces the number of molding steps and makes the connection between the connecting arm 22 and the sprayer 200 more reliable.

[0043] like Figure 5-6As shown, the sprayer mounting structure provided in this embodiment also includes a water distribution seat 3. The water distribution seat 3 is located on the side of the inner tank 100 base away from the inner tank chamber, directly opposite and connected to the mounting ring 1. Specifically, it is connected to the water outlet 101 through the first spray port 31 of the water distribution seat 3. The water distribution seat 3 also includes a water distribution valve interface 32, a motor interface 33, and a second spray port 34.

[0044] Specifically, the water distribution base 3 and the inner liner 100 are integrally molded. This design reduces installation steps, saves mold and labor costs, and lowers manufacturing costs.

[0045] In other embodiments, the sprayer base 2 may include a water inlet ring 21 and a connecting ring (not shown in the figure) disposed outside the water inlet ring 21 and coaxial with the water inlet ring 21. A limiting protrusion (not shown in the figure) is provided on the outer wall of the connecting ring, and a limiting ring 11 is provided on the inner wall of the mounting ring 1. The limiting protrusion engages with the limiting ring 11. However, compared with the connecting arm in this embodiment, the installation and disassembly of this type of limiting protrusion are relatively more difficult.

[0046] This embodiment also proposes a dishwasher, which includes a sprayer and an inner tank, as well as the sprayer mounting structure provided in this embodiment.

[0047] The dishwasher's sprayer 200 is installed on the inner tank 100 via the aforementioned sprayer mounting structure. After installation, the mounting structure is not exposed. Compared to the existing technology that uses a pipe joint on the bottom surface of the inner tank chamber, this effectively reduces the fixed height of the sprayer 200, thereby saving installation space. The connecting arm 22 and the mounting ring 1 are directly snapped together. Compared to the separate snap-on structure in the existing design, this effectively reduces the load on the sprayer 200. Under the same water pressure conditions, the sprayer 200 rotates faster, providing a better spraying effect.
