Description

Dishwasher rack

Technical field

[0001] The present invention relates to an adjustable height rack pan that is installed in the basket located in a dishwasher to receive the dirty dishes.

Prior art

[0002] The heights of the rack racks for cups that are used to increase the capacity of the upper baskets of the dishwashers to receive the dirty dishes, are located on the right and left edges of the basket and can be placed, so that a specific angle is formed with both the horizontal and the vertical and can be adjusted, so that the dirty dishes such as glasses or plates of different sizes are allowed to be washed. In the present systems, various mechanisms are used to adjust the height of the grid pan.

[0003] In the prior art, patent document WO2005 / 037050 contains overlapping hitch structures that are constructed to allow the basket to be placed at different levels on the thin side rods to allow height adjustment of the grid racks that They are placed on the thin side rods of the dishwasher basket. To allow the grid bat to remain balanced, there are two separate hitch structures at a specific distance and at the same level at which any grid bat can be installed. The bar-shaped structures that are located on the rear side of the grid trays are installed and fixed to the hooks at the desired height, thereby allowing the height of the grid rack to be adjusted. However, some problems may be experienced in this system while the grid trays are being installed in the hooks; in addition, the grid bats can be decoupled from the hooks while the grid bats are placed in an upright position and the grid bat should be separated from the basket each time to allow the height of the grid bat to be adjusted.

[0004] In the system disclosed in patent document TR 2002 00878, a pin containing a hook structure is inserted and fixed in its center that has a shape that can move along the vertical axis of the thin rod of the basket in the grooves that are located on the back side of the cup rack pan to allow the height of the cup rack rack adjusted to the side walls of the top basket of the dishwashers, in this way the rack of cups for cups at different heights is allowed to be placed when the grooving structure installed in said rack of cups for cups moves along the vertical axis of the thin rods of the basket. Sliding down the rack is avoided with a support member positioned perpendicular to the vertical thin rods that are located on the side of the basket. The pin that is fixed on the rear side of the grid bat constitutes the axis of rotation of the grid bat while moving from the horizontal position to the vertical position. However, in this system the cup rack can only be placed at two specific heights and cannot be placed at the upper levels of the support member. In addition, the pin that is attached to the rear side of the grid pan comes from a second mold. As a result, mounting this pin to the grid bat requires additional work.

[0005] On the rear side of an embodiment of the rack of a dishwasher, there are coupling housings whose interior is in the form of a long, thin channel. These housings are installed on the vertical thin rods of the basket and the height of the rack can be adjusted by moving it up and down and the rack can be opened and closed. In addition, the grid bat is allowed to be fixed to the basket with the gripping devices located on the rear side of the grid bat. In addition, the grid bat is allowed to remain in the vertical position without falling by means of the gripping devices that are located on the upper surface of the grid bat. The support surfaces in the form of a channel that are located on the lower side of the coupling housings help the grid pan to rest on the vertical thin rods of the basket when it is in the inclined position and is fixed to different heights also with the effect of friction force. Apart from these, since the dishwasher rack pan comes out of a single mold, it does not require any additional assembly work.

Object of the invention

[0006] An objective of the present invention is to allow the height of the rack pan located in the dishwasher basket to be adjusted to the desired level according to the size of the dirty dishes to be placed below or above it.

[0007] Another objective of the invention is to allow the height of the rack to be adjusted without separating it from the basket.

[0008] The other objective of the invention is to ensure that the grid bat maintains its position without sliding down due to the weight placed on it when it is in the inclined position.

[0009] Another object of the invention is to ensure that the grid pan forms a specific angle with the horizontal when it is in the inclined position to avoid the accumulation of water in the dirty dishes located in the rack pan during washing.

[0010] The other objective of the invention is to decrease the balancing and allow the grid bat to remain balanced in the position in which it is installed by ensuring that the bearing surfaces resting on the vertical thin rods of the basket are constructed in In the form of a channel, the rear gripping devices are fixed to the vertical thin rods with a snap fit and the width of the channel in the coupling housings is almost the width of the thin rod.

15 Disclosure of the invention

[0014] Figure 1 provides a perspective plan view of the content of the invention of the grid bat (3), in which it is fixed to a basket (1) of a dishwasher. The figure shows the open and closed positions of the rack pan (3) to increase the capacity of the basket (1) to receive dirty dishes. The open position is the position of the grid bat (3) in which it is inclined and placed in a state in which it can be

20 place the dirty dishes on it. The closed position is the position in which the grid bat (3) is placed in the vertical position.

[0015] The dishwasher rack (3), of which a perspective plan view is provided in Figure 2, comprises at least one coupling housing (4) that is placed on the rear surface (9), so that it allows the grid bat (3) to remain tilted in the open position (not shown in figure 25 9), extends outward from the rear surface (9) and is used for upward and forward movement down the rack (3) of grid on the vertical thin rods (2) in the basket (1); at least one support surface (7) in the form of a channel in which the vertical thin rods (2) rest on the internal surface thereof when the grid bat (3) is in the open position and is located on the lower side of the coupling housings (4) and on the rear surface (9) of the grid pan; at least one rear gripping device 30 (5) that is used to avoid changing the position it maintains due to any contact while there is dirty crockery in the rack pan (3) when attached to the vertical thin rods (2) when he hit her

(3) grid is in the open position, and is located on said rear surface (9); at least one upper gripping device (6) that is used to avoid changing the position of the grid bat (3) when fixed to the vertical thin rods (2) when the grid bat (3) is in the closed position and is located

35 on the upper surface (10) of the rack (3) rack. The distances between said coupling housings (4), the support surfaces (7), the rear gripping devices (5) and the upper gripping devices (6) are formed, so that each corresponds to the thin rods vertical (2).

[0016] Figure 3 provides a plan view of the coupling housing (4), while Figure 4 provides a perspective view of the coupling housing (4) and the supporting surface (7). To allow height adjustment of the rack bat (3) without completely separating it from the basket (1) and facilitate the movement of the rack bat (3) between the open and closed positions thereof, the housing (4 The coupling has a "C" shaped structure, its inner side is formed by a long and thin channel (13) and the vertical thin rod (2) can be passed through the opening (14) which extends towards the outside from the side of the channel (13). When the vertical thin rod (2) fits into said channel (13), due to the long structure of the

45 channel (13), the grid bat (3) can make a rotary movement with respect to the vertical thin rod (2). On the other hand, by keeping the width of said channel (13) close to the width of the thin rod inside it, movement to the left and right of the grid pan with respect to the basket (1) is avoided. .

[0017] Figure 5 provides a rear perspective view of the grid bat (3) in the open position, in which it is mounted on the vertical thin rods (2), and Figure 6 provides a side view thereof in 50 the same position. The grid pan (3) is placed at the desired height by moving the coupling housings (4) up and down on the vertical thin rods (2), then brought to the open position at the height

desired to be fixed and the rear gripping devices (5) are installed on the vertical thin rods (2), so that a snap fit is obtained. In this position, the support surfaces (7) also rest on the vertical thin rods (2). The weight of the dirty dishes placed on the rack pan (3) increases friction on the surfaces (7) resting on the vertical thin rods (2).

[0018] In addition to this, when the rear gripping device (5) is fixed to the vertical thin rods (2), it is ensured that the position holding the grid bat (3) remains unchanged due to any contact while there is dirty dishes on it in this position and the rack is allowed to remain at the desired height.

[0019] In addition, at the time of washing, in order to avoid the accumulation of water in the dirty dishes that have been placed in the rack pan (3), the coupling housing (4) is placed, as shown in the figure 9, on the rear surface (9), so that the grid bat (3) is allowed to remain tilted in the open position.

[0020] Figure 7 provides a perspective view of the grid bat (3) in the closed position in which it is mounted on the basket (1) and Figure 8 provides a side view of it in this position. By lowering the grid bat (3) to the level of the horizontal thin rod (8) that is located in the basket (1) when the rear gripping devices (5) located on the rear surface (9) of the bat ( 3) the grid is separated from the vertical thin rods (2) and the coupling housing (4) slides along the vertical thin rods (2), the coupling housing (4) is allowed to rest on the horizontal thin rod (8) and when placing the grid bat (3) in the closed position, the upper grip devices (6) are fixed to the vertical thin rods (2) and it is thus allowed that the grid bat (3) remain in the closed position without tipping over.

[0021] With the invention, the height of the rack pan (3) that is located in the dishwasher basket (1) can be adjusted to the desired level according to the size of the dirty dishes to be placed under it and there is no need to separate the rack rack (3) from the basket (1) for this adjustment procedure. In addition, by ensuring that the support surfaces (7) resting on the vertical thin rods (2) of the basket (1) are constructed in the form of a channel, the rear gripping devices (5) are fixed to the thin rods vertical

(2)

 with a snap fit and the width of the channel (13) in the coupling housings (4) is close to the width of the thin rod, the grid pan is prevented from moving to the right and left in the position in which it is installed and this reduces the balance of the grid pan and allows it to remain balanced.

[0022] In another embodiment of the invention, as shown in Figure 10, the flexible materials (15) have been placed on the rear surface (9) of the grid pan (3). These materials (15) are provided in the areas that come into contact with the thin rods of the basket on the rear surface (9) to allow the rack bat (3) to remain at different heights in the open position without slipping. Especially preferred are materials with a high coefficient of friction as a flexible material (15). Since flexible materials

(fifteen)

 they have an effect of increasing friction during their contact with the thin rods of the basket help the rack bat (3) to remain in the desired position.

[0023] As mentioned above, the grid bat (3) can be installed in the vertical thin rod (2) from the opening (14) in the coupling housing (4) with a single movement and the vertical thin rod (2) sits on said channel (13). Therefore, it is provided for the convenience of mounting the rack pan (3) in the basket (1). In addition, the production of the grid bat (3) as a single piece eliminates the need for assembly work in the production of the grid bat (3).

[0024] Figures 11 to 13 show an alternative embodiment of the invention. To place the wine glasses (16) in the rack pan (1) of the dishwasher, there are some clamping devices (3C) in the front of the rack bars (3). The placement in the grid rack (1) of wine glasses (16) of various heights and sizes is of great importance. The fact that the wine glasses (16) generally have a more elongated structure than that of the rest of the kitchen utensils causes them to fall when they are in the rack pan (1). Specifically, when the grid pan (1) contains few dishes, it is necessary that the wine glasses (16) be kept in balance. For this reason, some devices for securing the wine glasses (3C) have been placed in the front part of the grid racks (3) in such a way that they hold the feet of the wine glasses (16a, 16b). All clamping devices (3C) have "C" and / or "V" shaped structures that to some extent are intertwined and arranged side by side along the front of the grid ( 3). The part between the adjacent arms (3E, 3E ') of each adjacent clamping device (3C) is the housing groove (3a) of the foot of a wine glass (16a), as can be seen in Figure 13. Similarly, the component between the adjacent arms (3E, 3E ') of the two clamping devices (3C) and located next to each clamping device (3C) is a clamping groove (3b) for another type Standing glass of wine. To allow the feet (16a, 16b) to be attached to the grooves (3a, 3b), the clamping devices (3C) are flexible. Additionally, each arm (3E, 3E ’) has a downward curved shape with respect to the grid bat (3). In this way, the feet of the wine glasses (16a, 16b) are allowed to easily enter the grooves (3a, 3b). In addition, it is possible to place wine glasses of different lengths, since the height and angle of the rack pan (3) located in the basket (1) is adjustable.

[0025] Figure 14 shows a perspective view of the trays (3) of the present invention, in which the plates (17) are placed. In this way it is possible to prevent the plates (17) from tipping over, placing said plates (17) in the dishwasher basket (1) so that their upper sides are between the arms curved down (3E, 3E ') of the devices for holding wine glasses. Since the grid pan (3) can be opened and closed, it is also possible to place 817 plates of different diameters between the arms (3E, 3E ’).
