Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a push-type automatic stop protection device for dishwashers. Background Technology

[0002] In commercial dishwashers, washed dishes are transported outward via a conveyor belt, and then sorting workers remove the dishes. However, in actual operation, there are often cases where the dishes are not collected in time, causing them to move to the end of the conveyor belt and get stuck in the dishwasher, increasing the risk of damage to the equipment and dishes. Therefore, modern commercial dishwashers are equipped with automatic shutdown protection devices at the end of the conveyor belt.

[0003] Existing automatic shutdown protection devices work by installing a sliding baffle plate at the end of the dishwasher. When the dishes slide to the end, they contact the baffle plate, pushing it to move. At this point, the baffle plate contacts an internal brake switch, thus stopping the dishwasher. However, in existing solutions, the baffle plate mainly slides using a slide rail. The baffle plate has a large overall width, and due to assembly process and wear over time, the two ends of the baffle plate may become non-parallel during sliding. This can easily cause the baffle plate to jam, preventing the brake switch from being triggered. Furthermore, the design usually requires two sets of brake switches at both ends to ensure triggering, which increases the overall braking cost. Therefore, a push-type automatic shutdown protection device for dishwashers is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a push-type automatic stop protection device for dishwashers, which solves the problem that the baffle plates used for emergency braking protection in existing commercial dishwashers cannot ensure that both ends are flush when sliding, which easily leads to the baffle plates getting stuck and requires two sets of brake switches at both ends, thus increasing costs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a push-type automatic stop protection device for a dishwasher, comprising a cover plate and a blocking member, wherein the blocking member comprises a baffle slidably disposed in the cover plate and a blocking tooth integrally formed on the front side of the baffle. A return spring is installed between the baffle and the cover plate to allow the baffle to naturally protrude outward from the cover plate. The cover plate is equipped with a balance bar that rotates inside. The upper ends of the balance bar abut against the inner ends of the baffle, so that the two ends of the baffle are flush when it slides into the cover plate.

[0006] Preferably, the cover plate includes a fixed plate and a flip cover plate rotatably disposed on the fixed plate, and the baffle is slidably disposed at the bottom of the flip cover plate.

[0007] Preferably, a reinforcing plate is fixedly welded to the bottom of the flip cover, and the two sides of the reinforcing plate are bent downward to form a slide for the baffle to slide.

[0008] Preferably, sliders are fixedly installed on the top of both sides of the baffle, and the sliders are slidably connected to the top of the slide rail.

[0009] Preferably, the top of the slider is flush with the top of the reinforcing plate, so that the flip-top plate restricts the vertical movement space of the slider.

[0010] Preferably, the outer end of the reset spring is fixedly connected to the front end of the flip cover, and the inner end of the reset spring is fixedly connected to the baffle, so that the reset spring is stretched when the baffle slides into the flip cover.

[0011] Preferably, mounting blocks are rotatably connected to both sides of the bottom end of the balance bar, and the mounting blocks are fixedly installed on the inner side wall of the fixing plate.

[0012] Preferably, top blocks are fixedly installed on both sides of the bottom of the baffle, and the top blocks abut against the top two sides of the balance bar.

[0013] Preferably, both sides of the flip cover are fixedly welded with buckles, and the flip cover is movably engaged with the dishwasher through the buckles.

[0014] Preferably, a hinge is installed between the flip cover and the fixed plate.

[0015] This utility model discloses a push-type automatic stop protection device for a dishwasher, which has the following beneficial effects: During use, when the dishes move to the baffle position with the conveyor, the dishes press against the baffle, causing the baffle to slide inward along the slide rail. At this time, the baffle pulls the inner end of the return spring inward, causing the return spring to be stretched. Simultaneously, the two sets of top blocks at the bottom of the baffle abut against the top two sides of the balance rod, causing the bottom end of the balance rod to rotate around the mounting block, and the top of the balance rod to slide relative to the top block. During this process, the top two sides of the balance rod always remain abut against the two sets of top blocks, so that the two sides of the entire baffle remain parallel when sliding into the flip cover, thereby preventing the baffle from getting stuck during sliding. At the same time, there is no need to install two sets of brake switches, saving costs. Attached Figure Description

[0020] This application provides a push-type automatic stop protection device for dishwashers, which solves the problem that the baffle plates used for emergency braking protection in existing commercial dishwashers cannot be kept flush at both ends when sliding, which can easily lead to the baffle plates getting stuck and require two sets of brake switches at both ends, thus increasing costs.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This utility model discloses a push-type automatic stop protection device for a dishwasher.

[0023] According to the appendix Figure 1-5 As shown, it includes a cover plate 1 and a blocking member 2. The blocking member 2 includes a baffle 21 slidably disposed in the cover plate 1 and a blocking tooth 24 integrally formed on the front side of the baffle 21. A return spring 25 is installed between the baffle 21 and the cover plate 1 so that the baffle 21 naturally protrudes outward from the cover plate 1. The cover plate 1 is rotatably equipped with a balance bar 23. The upper ends of the balance bar 23 abut against the inner ends of the baffle 21, so that the two ends of the baffle 21 are flush when sliding into the cover plate 1.

[0024] The cover plate 1 includes a fixed plate 12 and a flip cover 11 rotatably disposed on the fixed plate 12, and a baffle 21 is slidably disposed at the bottom of the flip cover 11.

[0025] A reinforcing plate 14 is fixedly welded to the bottom of the flip cover 11. The two sides of the reinforcing plate 14 are bent downward to form a slide 16 for the baffle 21 to slide.

[0026] Slider 22 is fixedly installed on the top of both sides of the baffle 21, and slider 22 is slidably connected to the top of the slide rail 16.

[0027] The top of the slider 22 is flush with the top of the reinforcing plate 14 so that the flip cover 11 restricts the vertical movement space of the slider 22.

[0028] The outer end of the return spring 25 is fixedly connected to the front end of the flip cover 11, and the inner end of the return spring 25 is fixedly connected to the baffle 21, so that the return spring 25 is stretched when the baffle 21 slides into the flip cover 11.

[0029] Mounting blocks 27 are rotatably connected to both sides of the bottom end of the balance bar 23. The mounting blocks 27 are fixedly installed on the inner side wall of the fixing plate 12. Top blocks 26 are fixedly installed on both sides of the bottom of the baffle 21. The top blocks 26 abut against the top sides of the balance bar 23. The two sets of top blocks 26 at the bottom of the baffle 21 abut against the top sides of the balance bar 23, so that the bottom end of the balance bar 23 rotates around the mounting blocks 27, and the top end of the balance bar 23 slides relative to the top blocks 26. During this process, the top sides of the balance bar 23 always remain abutted against the two sets of top blocks 26.

[0030] Both sides of the flip cover 11 are fixedly welded with buckles 15, and the flip cover 11 is connected to the dishwasher through the buckles 15. The buckles 15 are made of elastic metal one-piece die casting.

[0032] Working principle: In use, the device is fixed to the dishwasher with bolts using a fixed plate 12. Then, the flip-top plate 11 is flipped inward, causing the latch 15 to engage with the dishwasher. Simultaneously, a set of brake switches, horizontally aligned with the baffle 21, is fixedly installed on the inner side of the cover plate 11. During use, when the dishes move to the baffle 21 position with the conveyor, the dishes press against the baffle 21, causing it to slide inward along the slide rail 16. At this time, the baffle 21 pulls the inner end of the return spring 25 inward, thus stretching the return spring 25. Meanwhile, the two sets of top blocks 26 at the bottom of the baffle 21 abut against the top sides of the balance bar 23, causing the bottom of the balance bar 23 to rotate around the mounting block 27, and the top of the balance bar 23 to slide relative to the top blocks 26. During this process, the top sides of the balance bar 23 always remain abut against the two sets of top blocks 26, so that the two sides of the entire baffle 21 remain parallel when sliding into the flip cover 11, thereby preventing the baffle 11 from getting stuck when sliding. At the same time, the inner side of the baffle 11 can effectively trigger the brake switch, eliminating the need to install two sets of brake switches and saving costs.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
