Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, and in particular to a sliding door device for an embedded dishwasher. Background Technology

[0002] like Figures 10-11 As shown, built-in dishwashers, due to their large capacity and integration into the cabinet 101, seamlessly blend with the cabinet 101 after the door panel 102 is installed, enhancing the overall aesthetics of the kitchen and thus gaining wider application. However, to maintain the overall aesthetics, the door panel 102 should cover the built-in dishwasher body. This can lead to interference between the door panel 102 and the dishwasher base 103 or the external environment during opening and closing, accelerating wear and tear on the door panel 102, damaging the connection structure between the door panel 102 and the built-in dishwasher, and affecting the overall appearance and performance.

[0003] To address the aforementioned issues, current solutions often involve reducing the length of the door panel 102 or adjusting the external environment, such as changing the installation position of the cabinet kickboard, to avoid interference between the door panel 102 and the base 103 or the external environment. While this method can solve the interference problem of the door panel 102 to some extent, reducing the length of the door panel 102 will cause a difference in appearance between the door panel 102 and the cabinet 101, affecting the overall aesthetics of the kitchen. On the other hand, changing the installation position of the cabinet kickboard will damage the structure of the cabinet 101 itself, affecting its performance, and is also cumbersome to operate, seriously reducing user satisfaction.

[0004] Therefore, further improvements are necessary. Utility Model Content

[0005] The purpose of this invention is to provide a sliding door device for an embedded dishwasher, which allows the door panel to slide when the door is opened, avoiding interference between the door panel and the base or the external environment, thus overcoming the shortcomings of the prior art.

[0006] A sliding door device for an embedded dishwasher designed for this purpose is characterized by comprising a door assembly, a linkage assembly, a door frame, a first hydraulic cylinder, and a second hydraulic cylinder. The door assembly includes a door shell and a door panel slidably mounted on the door shell. The door shell is hinged to the door frame via the linkage assembly, allowing the door assembly to open or close the embedded dishwasher. The linkage assembly connects to the first hydraulic cylinder, which is fixed to the door frame. The second hydraulic cylinder is fixed to the door shell and drives the door panel. The first and second hydraulic cylinders are connected via an oil circuit. When the door assembly opens or closes, the linkage assembly pushes the first hydraulic cylinder to perform a forward or backward movement. The first hydraulic cylinder, in conjunction with the second hydraulic cylinder, performs the forward or backward movement via the oil circuit, thereby driving the door panel to slide on the door shell.

[0007] When the door assembly is open, the door panel slides towards the top of the door shell; when the door assembly is closed, the door panel slides towards the bottom of the door shell.

[0008] The linkage assembly includes a hinge bracket, which is rotatably connected to the door frame. One end of the hinge bracket is connected to the door shell, and the door shell is hinged to the door frame via the hinge bracket.

[0009] The linkage assembly also includes a linkage, with one end of the hinge bracket rotatably connected to one end of the linkage, and the other end of the linkage rotatably connected to the first piston rod of the first hydraulic cylinder; when the door assembly opens or closes, it drives the hinge bracket to rotate on the door frame, and the hinge bracket drives the first piston rod forward or backward through the linkage.

[0010] The second piston rod of the second cylinder is connected to the door panel. When the first piston rod moves forward or backward, it moves forward or backward through the oil circuit, so that the second piston rod drives the door panel to slide on the door shell.

[0011] The first piston rod and the second piston rod move in opposite directions.

[0012] The front end of the first hydraulic cylinder is connected to the front end of the second hydraulic cylinder via the first hydraulic pipe, and the rear end of the first hydraulic cylinder is connected to the rear end of the second hydraulic cylinder via the second hydraulic pipe.

[0013] It also includes a sliding rail assembly, which is installed on the door shell and connected to the door panel. The door panel is slidably mounted on the door shell via the sliding rail assembly.

[0014] The slide rail assembly includes a fixed slide rail and a movable slide rail that are slidably connected to each other. The fixed slide rail is fixed to the door shell, and the movable slide rail is connected to the door panel. The door panel slides on the fixed slide rail via the movable slide rail.

[0015] The first hydraulic cylinder and connecting rod assembly are located on the left and right sides of the door frame, respectively, and the second hydraulic cylinder and slide rail assembly are located on the left and right sides of the door body assembly, respectively.

[0016] The sliding door device of this built-in dishwasher utilizes a linkage assembly, a first hydraulic cylinder, and a second hydraulic cylinder. When the door assembly opens or closes, the linkage assembly pushes the first hydraulic cylinder to move forward or backward. The first hydraulic cylinder, through an oil circuit, links the second hydraulic cylinder to move forward or backward, driving the door panel to slide on the door shell. Therefore, when the door is opened, the door panel can slide towards the top of the door shell, thus preventing interference between the door panel and the dishwasher base or external environment without affecting the overall aesthetics of the kitchen. Moreover, the sliding door device only requires rotating the door body to slide the door panel, making operation simple and effectively improving user satisfaction. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] See Figures 1-8 The sliding door device of this built-in dishwasher includes a door assembly, a linkage assembly, a door frame 1, a first hydraulic cylinder 2, and a second hydraulic cylinder 3. The door assembly includes a door shell 4 and a door panel 5 that slides vertically on the outside of the door shell 4. The door shell 4 is hinged to the door frame 1 via the linkage assembly, so that the door assembly can open or close the built-in dishwasher. The linkage assembly connects to the first hydraulic cylinder 2, which is fixed to the door frame 1. The second hydraulic cylinder 3 is fixed to the door shell 4 and drives the door panel 5. The first hydraulic cylinder 2 and the second hydraulic cylinder 3 are connected via an oil circuit. When the door assembly opens or closes, the linkage assembly pushes the first hydraulic cylinder 2 to perform a forward and backward movement. The first hydraulic cylinder 2, through the oil circuit, links the second hydraulic cylinder 3 to perform a forward and backward movement, thereby driving the door panel 5 to slide vertically on the door shell 4.

[0030] When the door assembly is opened, the door panel 5 slides towards the top of the door shell 4 to prevent the door panel 5 from interfering with the base 15 of the built-in dishwasher when the door is opened to a certain angle; when the door assembly is closed, the door panel 5 slides towards the bottom of the door shell 4.

[0031] The linkage assembly includes a hinge bracket 6, which is rotatably connected to the door frame 1. One end of the hinge bracket 6 is connected to the door shell 4, and the door shell 4 is hinged to the door frame 1 through the hinge bracket 6, so that the door assembly is rotatably connected to the door frame 1.

[0032] The linkage assembly also includes a linkage 7. The other end of the hinge bracket 6 is rotatably connected to one end of the linkage 7, and the other end of the linkage 7 is rotatably connected to the first piston rod 8 of the first hydraulic cylinder 2. When the door assembly opens or closes, it drives the hinge bracket 6 to rotate on the door frame 1. The hinge bracket 6 drives the first piston rod 8 to move forward or backward through the linkage 7. When the hinge bracket 6 rotates, it drives the linkage 7 to swing. When the linkage 7 swings, it drives the first piston rod 8 to move forward or backward, that is, it pushes the first hydraulic cylinder 2 to perform forward and backward movements.

[0033] The second piston rod 9 of the second cylinder 3 is connected to the door panel 5. When the first piston rod 8 moves forward or backward, it moves forward or backward through the oil circuit, so that the second piston rod 9 drives the door panel 5 to slide up and down on the door shell 4.

[0034] The first piston rod 8 and the second piston rod 9 move in opposite directions. That is, when the first piston rod 8 moves forward, the second piston rod 9 moves backward, and when the first piston rod 8 moves backward, the second piston rod 9 moves forward. This enables the door panel 2 to slide towards the top of the door shell 4 when the door assembly opens, and the door panel 2 to slide towards the bottom of the door shell 4 when the door assembly closes.

[0035] The front end of the first hydraulic cylinder 2 is connected to the front end of the second hydraulic cylinder 3 through the first oil pipe 10, and the rear end of the first hydraulic cylinder 2 is connected to the rear end of the second hydraulic cylinder 3 through the second oil pipe 11, thereby connecting the first hydraulic cylinder 2 and the second hydraulic cylinder 3 through an oil circuit, and connecting the first hydraulic cylinder 2 and the second hydraulic cylinder 3 in series.

[0036] It also includes a slide rail assembly 12, which is installed on the door shell 4 and connected to the door panel 5. The door panel 5 is slidably mounted on the door shell 4 via the slide rail assembly 12, thereby enabling the door panel 2 to slide to the top or bottom of the door shell 4.

[0037] The slide rail assembly 12 includes a fixed slide rail 13 and a movable slide rail 14 that are slidably connected to each other. The fixed slide rail 13 is fixed on the door shell 4, and the movable slide rail 14 is connected to the door panel 5. The door panel 5 slides up and down on the fixed slide rail 13 via the movable slide rail 14.

[0038] The first hydraulic cylinder 2 and the connecting rod assembly are located on the left and right sides of the door frame 1, respectively, and the second hydraulic cylinder 3 and the slide rail assembly 12 are located on the left and right sides of the door body assembly, thereby achieving sliding balance of the door panel 5.

[0039] The built-in dishwasher includes a body 16, with a door frame 1 located on the front side of the body 16.

[0040] The working principle of the sliding door mechanism of this built-in dishwasher: When the door assembly is opened, the hinge bracket 6 rotates with the door assembly. The hinge bracket 6 pushes the first piston rod 8 of the first oil cylinder 2 through the connecting rod 7, so that the first piston rod 8 moves backward. The oil in the first oil cylinder 2 is transmitted to the rear end of the second oil cylinder 3 through the second oil pipe 11, so as to push the second piston rod 9 of the second oil cylinder 3 forward. Then the second piston rod 9 pushes the door panel 2 to slide towards the top of the door shell 4. The oil at the front end of the second oil cylinder 3 returns to the front end of the first oil cylinder 2 through the first oil pipe 10.

[0041] When the door assembly is closed, the hinge bracket 6 rotates with the door assembly. The hinge bracket 6 pulls the first piston rod 8 of the first oil cylinder 2 through the connecting rod 7, so that the first piston rod 8 moves forward. The oil in the first oil cylinder 2 is transmitted to the front end of the second oil cylinder 3 through the first oil pipe 10, so as to push the second piston rod 9 of the second oil cylinder 3 backward. Then the second piston rod 9 pulls the door panel 2 to slide towards the bottom of the door shell 4. The oil at the rear end of the second oil cylinder 3 returns to the rear end of the first oil cylinder 2 through the second oil pipe 11.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
