[0006] Preferably, a square fixing block is provided on the top of the guide rail seat, the square fixing block passes through the top wall of the inner container of the dishwasher, and the square fixing block is connected to the top wall of the inner container of the dishwasher by side buckles.

[0007] Preferably, the square fixing block is fixedly connected to the top wall of the inner tank of the dishwasher by means of screws, and a sealing gasket is sandwiched between the screws and the top of the inner tank of the dishwasher.

[0008] Preferably, the lower end of the guide rail seat is formed with two arc-shaped seat bodies with opposite inner concave surfaces, and the bayonet is formed between the two arc-shaped seat bodies.

[0009] Preferably, a plurality of straight ridges are formed on the inner wall of the arc-shaped seat, and the straight ridges and the columnar ribs abut against each other and are slidably matched.

[0010] Preferably, each slide rail is correspondingly provided with two guide rail seats.

[0011] Preferably, the columnar ribs are ribs with an elliptical cross-section.

[0012] Preferably, an upper arc-shaped edging and a lower arc-shaped edging are formed on the side of the slide rail, and the slide groove is formed between the upper arc-shaped edging and the lower arc-shaped edging.

[0013] Preferably, the front and rear ends of the slide rail are respectively engaged with plugs, and the plug includes an end plate, and the end plate protrudes upward from the slide rail.

[0014] Preferably, two fixed shafts are provided on each side edge of the top tray, and a roller is sleeved on each fixed shaft.

[0015] In the guide rail mechanism of the top tray of the dishwasher disclosed in the utility model, the top tray is a hollow tray and can be used for loading tableware such as spoons and chopsticks. Based on the rolling cooperation relationship between the roller and the slide groove, the top tray can be pulled outward relative to the slide rail. Further, based on the sliding cooperation relationship between the columnar rib and the bayonet, the slide rail can be pulled outward corresponding to the guide rail seat. This structure adopts a two-stage sliding method to make the top tray have a longer stretching distance. At the same time, because the guide rail seat is fixed to the top wall of the dishwasher inner tank, it does not occupy the side wall of the dishwasher inner tank. Compared with the prior art, the utility model moves the guide rail seat supporting the slide rail to the top wall of the dishwasher inner tank, effectively saving the side space of the dishwasher inner tank, thereby avoiding position interference with the middle and lower trays, and facilitating the layout of the middle and lower trays, so that the internal space of the dishwasher inner tank is reasonably utilized.

[0020] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0021] The utility model discloses a guide rail mechanism for a top tray of a dishwasher. Figures 1 to 4As shown, it includes a top tray 1, two slide rails 2 and a guide rail seat 3 corresponding to each slide rail 2, the guide rail seat 3 is fixedly connected to the top wall of the dishwasher inner tank 6, the lower end of the guide rail seat 3 is formed with a bayonet 30, the upper end of the slide rail 2 is formed with a columnar rib 20, the columnar rib 20 is clamped in the bayonet 30 and the two are slidably matched, the two slide rails 2 are respectively arranged on the left and right sides of the top tray 1, the slide rail 2 is formed with a slide groove 21 on the side facing the top tray 1, the edge of the top tray 1 is provided with a roller 4, the roller 4 is clamped in the slide groove 21 and the two are rollingly matched.

[0022] In the above structure, the top tray 1 is a hollow tray, which can be used to load tableware such as spoons and chopsticks. Based on the rolling cooperation relationship between the roller 4 and the slide groove 21, the top tray 1 can be pulled outward relative to the slide rail 2. Further, based on the sliding cooperation relationship between the columnar rib 20 and the bayonet 30, the slide rail 2 can be pulled outward corresponding to the guide rail seat 3. This structure adopts a two-stage sliding method, so that the top tray 1 has a longer stretching distance. At the same time, because the guide rail seat 3 is fixed to the top wall of the dishwasher inner tank 6, it does not occupy the side wall of the dishwasher inner tank 6. Compared with the prior art, the utility model moves the guide rail seat 3 supporting the slide rail 2 to the top wall of the dishwasher inner tank 6, effectively saving the side space of the dishwasher inner tank 6, thereby avoiding position interference with the middle and lower trays, and facilitating the layout of the middle and lower trays, so that the internal space of the dishwasher inner tank 6 is reasonably utilized.

[0023] In order to reliably fix the guide rail seat 3, in the present embodiment, a square fixing block 31 is provided on the top of the guide rail seat 3, the square fixing block 31 passes through the top wall of the dishwasher inner tank 6, and the square fixing block 31 is connected to the top wall of the dishwasher inner tank 6 by a side buckle 32.

[0024] Furthermore, the square fixing block 31 is fixedly connected to the top wall of the dishwasher inner tank 6 by screws, and a sealing gasket 33 is sandwiched between the screws and the top of the dishwasher inner tank 6 .

[0025] When assembling the above structure, Figure 3 and Figure 4 As shown, the square fixing block 31 is first passed through the square hole preset on the top wall of the dishwasher inner tank 6, and then the side buckle 32 is used to pre-fasten it to the edge of the square hole, and then the sealing gasket 33 is covered on the top of the square hole, and the sealing gasket 33, the top wall and the square fixing block 31 are fixed by screws passing through the sealing gasket 33. The installation process is simple and convenient, and the airtightness of the dishwasher inner tank 6 can be improved.

[0026] In order to match well with the columnar rib 20, in this embodiment, see Figure 4The lower end of the guide rail seat 3 is formed with two arc-shaped seat bodies 34 with opposite inner concave surfaces, and the bayonet 30 is formed between the two arc-shaped seat bodies 34. The two arc-shaped seat bodies 34 can not only reliably engage the columnar ribs 20, but also slide with them.

[0027] On this basis, the inner wall of the arc-shaped seat body 34 is formed with a plurality of straight ridges 35, and the straight ridges 35 abut against the columnar ribs 20 and the two slide together. In this embodiment, by providing the laterally extending straight ridges 35, the straight ridges 35 can directly contact the columnar ribs 20, reduce the contact area between the columnar ribs 20 and the arc-shaped seat body 34, and thus improve the smoothness between the columnar ribs 20 and the arc-shaped seat body 34.

[0028] In order to reliably support the slide rails 2 , in this embodiment, each slide rail 2 is correspondingly provided with two guide rail seats 3 .

[0029] As a preferred embodiment, the columnar rib 20 is a rib with an elliptical cross section. Further, the side of the slide rail 2 is formed with an upper arc-shaped edge 22 and a lower arc-shaped edge 23, and the slide groove 21 is formed between the upper arc-shaped edge 22 and the lower arc-shaped edge 23. The columnar rib 20, the upper arc-shaped edge 22 and the lower arc-shaped edge 23 are integrated profiles.

[0030] Combination Figures 1 to 3 As shown, the front and rear ends of the slide rail 2 are respectively engaged with plugs 5, and the plugs 5 include end plates 50, and the end plates 50 protrude upward from the slide rail 2. The end plates 50 protrude slightly upward, and when the slide rail 2 slides to the end position relative to the guide rail seat 3, the protruding portion of the end plates 50 abuts against the guide rail seat 3, thereby limiting the relative sliding stroke of the two, and preventing the slide rail 2 from falling off from the guide rail seat 3.

[0031] In order to reliably install the roller 4 , in this embodiment, two fixed shafts 10 are provided on each side edge of the top tray 1 , and a roller 4 is sleeved on each fixed shaft 10 .

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
