[0069] Further, in certain optional embodiments, see Figure 2 and Figure 3 As shown, the sum of the maximum moving stroke A of the first guide rail 101 and the maximum moving stroke B of the second guide rail 102 is greater than the length L of the shelf 200 .

[0070] In this embodiment, A+B=C, C>L, thereby ensuring that the shelf 200 is completely pulled out to the outside of the inner container.

[0071] The first fixing member 103 and the second fixing member 104 are respectively provided with slots for fixing the first guide rail 101 and the second guide rail 102 .

[0072] Furthermore, in certain optional embodiments, a first card slot 107 and a second card slot 108 are provided on one side of the first fixing member 103, one end of the first guide rail 101 is fixed inside the first card slot 107, and one end of the second guide rail 102 is fixed inside the second card slot 108; a third card slot 109 and a fourth card slot 110 are provided on one side of the second fixing member 104, the other end of the first guide rail 101 is fixed inside the third card slot 109, and the other end of the second guide rail 102 is fixed inside the fourth card slot 110.

[0073] During use, a guide rail assembly is typically provided on each of the left and right sides of the inner container. The first engaging slot 107 is provided on the side of the first fixing member 103 that is close to the side wall of the inner container. In other words, the notches of the first engaging slot 107 on the left and right sides of the inner container are arranged opposite to each other. Similarly, the notches of the second engaging slot 108, the third engaging slot 109, and the fourth engaging slot 110 on the left and right sides of the inner container are also arranged opposite to each other. This arrangement facilitates assembly of the guide rail assembly.

[0074] It should be noted that the arrangement of the first card slot 107 , the second card slot 108 , the third card slot 109 and the fourth card slot 110 is not limited to the above one, and can also be arranged according to actual production and processing needs.

[0091] See also Figure 12As shown, when the second guide rail 102 is slidably connected to the high-position mounting position 112, the shelf 200 is in a high position, and the space below the shelf 200 is increased, so that higher tableware, such as higher teacups or high-foot glasses, can be placed below for washing.

[0092] See also Figure 13 As shown, when the second guide rail 102 is slidably connected to the low mounting position 111 , the shelf 200 is in a low position, and the distance between the shelf 200 and the top of the inner pot is larger, which makes it easier to place larger tableware on the shelf 200 , such as a larger soup spoon.

[0093] By adopting a plurality of first installation positions 1061 spaced apart along the height direction of the inner tank, a flexible and varied way of placing tableware can be provided, thereby improving the utilization rate of the internal space of the dishwasher.

[0094] Example 3

[0095] See also Figure 14 and Figure 15 As shown, this embodiment also provides a guide rail device. The guide rail device of this embodiment is an improvement on the basis of the first embodiment. The technical solutions of the first embodiment also belong to this embodiment and will not be described again here. The same parts use the same reference numerals as the first embodiment, and reference is made to the description of the first embodiment here.

[0096] In this embodiment, there are multiple second guide rails 102 , and the multiple second guide rails 102 are arranged at intervals along the vertical direction.

[0097] Optionally, in this embodiment, there are two second guide rails 102 , which are respectively named as a high-position guide rail 114 and a low-position guide rail 115 , and the high-position guide rail 114 is located above the low-position guide rail 115 .

[0098] See also Figure 14 As shown, when the high-position guide rail 114 is slidably connected to the second mounting position 1062, the space below the shelf 200 is increased, and higher tableware, such as higher teacups or goblets, can be placed thereunder for washing.

[0099] See also Figure 15 As shown, when the low guide rail 115 is slidably connected to the second mounting position 1062 , the distance between the shelf 200 and the top of the inner pot is larger, making it easier to place larger tableware, such as a larger soup spoon, on the shelf 200 .

[0100] Example 4

[0101] See also Figure 16 and Figure 17As shown, this embodiment also provides a guide rail device. The guide rail device of this embodiment is an improvement on the basis of the first embodiment. The technical solutions of the first embodiment also belong to this embodiment and will not be described again here. The same parts use the same reference numerals as the first embodiment, and reference is made to the description of the first embodiment here.

[0102] In this embodiment, the first guide rail 101 is in the shape of a straight rod, and the second guide rail 102 includes a plurality of rod segments of unequal heights. Specifically, the second guide rail 102 includes a low rod segment 116, a transition rod segment 117, and a high rod segment 118. One end of the low rod segment 116 is fixedly connected to one end of the first guide rail 101, the other end of the low rod segment 116 is fixedly connected to one end of the transition rod segment 117, the other end of the transition rod segment 117 is fixedly connected to one end of the high rod segment 118, and the other end of the high rod segment 118 is fixedly connected to the other end of the first guide rail 101; the distance between the low rod segment 116 and the first guide rail 101 is greater than the distance between the high rod segment 118 and the first guide rail 101.

[0103] Optionally, in use, the high-position rod section 118 is close to the opening of the inner pot, and the low-position rod section 116 is away from the opening of the inner pot. When the user pulls the shelf 200 outward, the shelf 200 can move along the direction of the second guide rail 102. When the shelf 200 is in a fully pulled-out state, compared with the position of the shelf 200 in the inner pot, it rises a set distance H in the vertical direction, so that the user can place tableware on the shelf 200 or take tableware off the shelf 200 without bending too much, thereby improving the user experience.

[0104] In addition, when the rack 200 is pushed back into the inner pot, the position of the rack 200 is lower, so that there is a large distance between the rack 200 and the top of the inner pot, thereby ensuring that the dishes do not interfere with the top spray arm during washing.

[0105] It should be noted that the lower rod section 116 can also be positioned closer to the opening of the inner pot, while the upper rod section 118 is positioned further away from the opening of the inner pot. When the shelf 200 is pushed back into the inner pot, the shelf 200 is positioned higher, leaving more vertical space below the shelf 200, allowing for placement of taller tableware. This is also suitable for smaller children to help clear away the dishes.
