Description

Technical Field

[0001] The utility model discloses a frame-type upper cover ascending structure for a lid-lifting dishwasher, belonging to the technical field of dishwashers. Background Art

[0002] A dishwasher is a device that automatically washes tableware such as bowls, chopsticks, plates, dishes, knives, forks, etc. The fully automatic dishwashers on the market can be divided into two categories: household and commercial. However, most commercial dishwashers are prone to uneven force when rising and falling during the opening and closing operation due to the heavy weight of the door cover itself. In particular, the door cover is prone to tilting back and forth when rising, and there will be a phenomenon of not being smooth during the rising and falling process, which is more troublesome to use.

[0003] For this purpose, Chinese patent publication number CN217244224U discloses a frame-type upper cover lifting structure for a lid-type dishwasher. The frame-type upper cover lifting structure solves the problem that the frame-type door cover of a traditional commercial dishwasher is inconvenient to operate during the opening and closing process by installing a door rod of a connecting structure on the outside of the door cover and connecting the door rod and a tension spring together. The front door support frame is used to support and fix the door cover. However, the tension spring in the frame-type upper cover lifting structure is arranged on the outside, which is easily corroded and damaged in a greasy environment in the kitchen, affecting the use and having certain limitations. Therefore, there is an urgent need for a frame-type upper cover lifting structure for a lid-type dishwasher to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 4The utility model provides a technical solution: a frame-type upper cover rising structure of a lid-lifting dishwasher, comprising a dishwasher body 1, a door cover 2, a bottom support rod 3, a stabilizing component 4, a guide rail slot 5, a door rod 6, a spring coil group 7, a limit component 8 and a pull rope 9. A plurality of bottom support rods 3 are arranged at the bottom of the dishwasher body 1, and guide rail slots 5 are also arranged at the left and right ends of the top rear side of the dishwasher body 1. The stabilizing component 4 is installed at the front side of the top of the dishwasher body 1, and the stabilizing component 4 is also connected to the door cover 2. The door cover 2 is also equipped with a door rod 6, and spring coil groups 7 are added to the interfaces at both ends of the door rod 6. The spring coil group 7 is connected to the limit component 8 through the pull rope 9. The stabilizing component 4 includes a connecting block 41, a first sleeve 42, a telescopic Rod 43, second sleeve 44 and barrier layer 45, the connecting block 41 is arranged on the inner side of the door cover 2, and the bottom of the connecting block 41 is connected to the first sleeve 42, the first sleeve 42 docks with the telescopic rod 43, the bottom of the telescopic rod 43 is installed in the second sleeve 44, and a barrier layer 45 is also added to the bottom of the second sleeve 44, the limiting assembly 8 includes a support block 81, a track pulley 82, a linkage shaft 83, a limiting hook 84 and an outer protective block 85, the support block 81 is arranged on the rear side of the door cover 2, and the support block 81 is also equipped with a track pulley 82, the track pulley 82 is connected to the outer protective block 85 through the linkage shaft 83, and the outer protective block 85 is also provided with a limiting hook 84, and the limiting hook 84 is fixed on the linkage shaft 83.

[0020] As the first embodiment of the utility model: the width of the guide rail slot 5 matches the size of the track pulley 82 in the limit assembly 8. The design uses the track pulley 82 to slide up and down in the guide rail slot 5 to realize the switch closure of the door cover 2. The structure is simple and convenient for personnel to operate. The pull rope 9 is woven with multiple fine steel wires. The design structure is reasonable, which greatly improves the toughness of the pull rope 9. The size between the telescopic rod 43, the first sleeve 42 and the second sleeve 44 is continuously increased, that is, the telescopic rod 43 is inserted into the first sleeve 44. In the sleeve 42, the first sleeve 42 is inserted into the second sleeve 44. The design adopts the stretching method of the telescopic rod 43 to help the door cover to support and fix it, thereby improving the stability during use. The middle part of the support block 81 and the outer protective block 85 are provided with empty grooves for inserting the pull rope 9. The top of the limiting hook 84 is fixed to the pull rope 9 by welding. The design uses the pull rope 9 to tighten the limiting hook 84, which helps the limiting hook 84 to clamp the linkage shaft 83, thereby ensuring that the track pulley 82 can be stable on the guide rail slot 5.

[0021] As a second embodiment of the present utility model: when the dishwasher is in use, the user needs to lift the door rod 6 upwards first, and when the door rod 6 is lifted, it will rotate to a certain extent, and the spring coil group 7 on the door rod 6 will rotate together, so that the pulling rope 9 connected to the spring coil group 7 will pull the limiting hook 84 on the limiting assembly 8. Due to the pulling of the pulling rope 9, the limiting hook 84 will deviate from the linkage shaft rod 83, and lose the clamping limit on the linkage shaft rod 83. The user can pull the door cover 2 downwards, and the support block 81 and the track pulley 82 will slide downwards on the guide rail slot 5, so that the door cover 2 and the dishwasher body 1 are closed, and the dishwashing work is carried out. When the personnel restores the door rod 6 to a vertical state, the spring coil group 7 will be reset due to the effect of elastic potential energy, so that the pulling rope 9 will no longer pull the limiting hook 84, thereby achieving the effect of clamping the linkage shaft rod 83, so that the track pulley 82 connected to the linkage shaft rod 83 will stop and remain fixed on the guide rail slot 5. In order to further keep the dishwasher stable when opening and closing, when the door cover 2 moves, the first sleeve 42 fixed by the connecting block 41 will retract into the telescopic rod 43, and the telescopic rod 43 will retract into the second sleeve 44 accordingly. With the help of the stabilizing components 4 at the left and right ends of the front side, the stability is improved to a higher level, and there will be no shaking or even tilting forward and backward during operation.

[0022] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
