Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a cleaning machine for cleaning tableware, fruits and vegetables. Background Technology

[0002] A dishwasher is a device that sprays cold or hot water onto dishes to remove dirt and grime and clean them. Dishes are placed in dish racks inside a dishwasher cabinet. A typical dishwasher includes a pump and spray nozzles for spraying washing water, and a heater for generating hot water.

[0003] For example, the applicant's prior patent ZL 202420944254.8 "A Cleaning Machine" discloses a structure that includes a box, a door, and a hinge assembly. The hinge assembly includes a door hinge, a pull rope, and an elastic element. The elastic element is horizontally disposed on the side of the box base, with its front end constrained on the base and its rear end connected to the second end of the pull rope. The elastic element is made by winding a long strip of metal sheet circumferentially and stacking and compressing it axially. Each time the elastic element is wound, it presents at least two troughs and two peaks in the axial direction. In two interconnected turns, the trough part of the previous turn abuts against the peak part of the next turn to form an elastic support position. Due to the increased width of the elastic element and the improved sensitivity of the elastic support to the transmission of elastic force, the tensile force per unit area can be increased.

[0004] Using the aforementioned hinge assembly structure requires two sets symmetrically installed on both sides of the door, which is not only structurally complex but also costly. Furthermore, if the springs on both sides wear out over time and at different rates, it can easily lead to imbalance during door opening, potentially causing problems with the door's sealing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a cleaning machine that can maintain the force balance on both sides of the door and thus avoid problems such as door sealing, in view of the current situation of the prior art.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A cleaning machine includes an inner tank, a door, and a hinge assembly. The inner tank has an opening at its front side, and the bottom of the door is rotatably disposed at the bottom edge of the opening for opening or closing. The hinge assembly includes...

[0008] A first door hinge is provided on the first side of the door body, and the rear part of the first door hinge is rotatably connected to the first side of the inner liner.

[0009] A second door hinge is provided on the second side of the door body, and the rear part of the second door hinge is rotatably connected to the second side of the inner liner.

[0010] The first pull rope has its first end connected to the rear end of the first door hinge, and its second end extended to the bottom of the inner liner after the guide wheel supports the reversal.

[0011] The second pull rope has its first end connected to the rear end of the second door hinge, and its second end extends to the bottom of the inner liner after being reversed by a guide wheel.

[0012] An elastic element is horizontally disposed below the inner liner and between the first pull rope and the second pull rope. The first end of the elastic element is connected to the second end of the first pull rope, and the second end of the elastic element is connected to the second end of the second pull rope.

[0013] The above structure uses an elastic element as a retractable balancer in the middle. Door hinges and pull ropes are symmetrically arranged on both sides of the elastic element. The force applied to the door hinge on one side of the door supports and balances the force applied to the door hinge on the other side of the door, so that the door is always subjected to balanced forces on both sides. This avoids the problem of one-sided wear of the hinge assembly, improves the reliability of the door opening and closing, and avoids problems such as door sealing.

[0014] Preferably, the bottom of the inner liner is supported on the base, and a receiving cavity is formed between the bottom of the inner liner and the base. The elastic element and the first pull rope portion and the second pull rope portion connected to it are laterally arranged in the receiving cavity. By adopting the above structure and placing the elastic element and the corresponding pull rope in the receiving cavity, not only is the space above the base fully utilized, but the elastic element that needs to expand and contract can also be protected to ensure the reliability of the structure.

[0015] Preferably, the guide wheel includes a first guide wheel and a second guide wheel. The first guide wheel is axially transversely rotatably mounted on the left side wall of the base, and the second guide wheel is axially longitudinally rotatably mounted on the top of the left side wall of the base. The first pull rope passes sequentially around the bottom of the first guide wheel and the outside of the second guide wheel, extending laterally into the receiving cavity and connecting to the first end of the elastic element. Preferably, the guide wheel also includes a third guide wheel and a fourth guide wheel. The third guide wheel is axially transversely rotatably mounted on the right side wall of the base, and the fourth guide wheel is axially longitudinally rotatably mounted on the top of the right side wall of the base. The second pull rope passes sequentially around the bottom of the third guide wheel and the outside of the fourth guide wheel, extending laterally into the receiving cavity and connecting to the second end of the elastic element. Using the above scheme, a simple structure provides precise and short-stroke guidance for the pull rope, thereby improving the stability and reliability of door opening and closing.

[0016] Preferably, the first and second door hinges have identical structures, each including a first sheet metal part and a second sheet metal part. The first sheet metal part is constrained to the bottom of the side wall of the inner liner near the opening. A protruding post is provided on the side of the first sheet metal part near the front end. The bottom of the second sheet metal part has a mating hole that can rotatably engage with the protruding post. The front edge of the second sheet metal part is located in front of the opening and connects to the side wall of the door. A hook with an upward-facing opening is provided at the rear end of the second sheet metal part. The first end of the first pull rope / second pull rope forms a hook that can be hung on the hook. This structure not only facilitates the assembly of the door hinges but also ensures high assembly reliability.

[0017] Preferably, the upper edge of the base sidewall has a downward-opening socket near the front end, and the rear end of the first sheet metal part has a downward-extending insertion arm that inserts into the socket. Since the first sheet metal part experiences significant force during door opening and closing, this structure provides vertical support and locking for the first sheet metal part, thereby improving the reliability of the fit between the two sheet metal parts.

[0018] To facilitate connection and assembly, the base sidewall and the plug-in arm are respectively provided with first connection holes for screws to pass through and lock the two together. The front part of the second sheet metal part forms a connecting arm that extends vertically in front of the opening. This connecting arm is arranged corresponding to the inner sidewall of the door, and both are respectively provided with second connection holes for screws to pass through and lock together.

[0019] Compared with the prior art, the advantages of this utility model are as follows: This utility model uses an elastic element as a telescopic balancer in the middle, and symmetrically arranged door hinges and pull ropes are set on both sides of the elastic element. The force applied to the door hinge on one side of the door is used to support and balance the force applied to the door hinge on the other side of the door, so that the two sides of the door are always subjected to balanced forces, thereby avoiding the problem of unilateral wear of the hinge assembly, improving the reliability of the door opening and closing, and avoiding the occurrence of door sealing problems.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1-5 As shown, the cleaning machine of this embodiment includes an inner tank 1, a door 2, and a hinge assembly 3. The inner tank 1 has an opening on its front side, and the bottom of the door 2 is rotatably disposed at the bottom edge of the opening for opening or closing. The hinge assembly 3 includes:

[0027] The first door hinge 31 is located on the first side of the door body 2, and the rear part of the first door hinge 31 is rotatably connected to the first side of the inner liner 1.

[0028] The second door hinge 32 is located on the second side of the door body 2, and the rear part of the second door hinge 32 is rotatably connected to the second side of the inner liner 1.

[0029] The first pull rope 01 has its first end connected to the rear end of the first door hinge 31, and its second end extends to the bottom of the inner liner 1 after the guide wheel supports the reversal.

[0030] The second pull rope 02 has its first end connected to the rear end of the second door hinge 32, and its second end extended to the bottom of the inner liner 1 after being reversed by the guide wheel support.

[0031] The elastic element 33 is horizontally disposed below the inner liner 1 and located between the first pull rope 01 and the second pull rope 02. The first end of the elastic element 33 is connected to the second end of the first pull rope 01, and the second end of the elastic element 33 is connected to the second end of the second pull rope 02.

[0032] With the above structure, the elastic element 33 is used as the middle retractable balance element. The door hinges and pull ropes are symmetrically arranged on both sides of the elastic element 33. The force applied to the door hinge on one side of the door is used to support and balance the force applied to the door hinge on the other side of the door, so that the door body 2 is always subjected to balanced forces. This avoids the problem of unilateral wear of the hinge assembly 3, thereby improving the opening and closing reliability of the door body 2 and avoiding the occurrence of problems such as sealing of the door body 2.

[0033] In this embodiment, the bottom of the inner liner 1 is supported on the base 4, and a receiving cavity 40 is formed between the bottom of the inner liner 1 and the base 4. The elastic element 33 and the first pull rope 01 portion and the second pull rope 02 portion connected to it are laterally arranged in the receiving cavity 40. By adopting the above structure, placing the elastic element 33 and the corresponding pull rope in the receiving cavity 40 not only makes full use of the space above the base 4, but also provides protection for the elastic element 33 that needs to expand and contract, thus ensuring the reliability of the structure.

[0034] The aforementioned guide wheels include a first guide wheel 301, a second guide wheel 302, a third guide wheel 303, and a fourth guide wheel 304. The first guide wheel 301 is rotatably mounted on the left side wall of the base 4, positioned horizontally. The second guide wheel 302 is rotatably mounted on the top of the left side wall of the base 4, positioned vertically. The first pull rope 01 passes sequentially around the bottom of the first guide wheel 301 and the outside of the second guide wheel 302, extending laterally into the receiving cavity 40 and connecting to the first end of the elastic member 33. The third guide wheel 303 is rotatably mounted on the right side wall of the base 4, positioned horizontally. The fourth guide wheel 304 is rotatably mounted on the top of the right side wall of the base 4, positioned vertically. The second pull rope 02 passes sequentially around the bottom of the third guide wheel 303 and the outside of the fourth guide wheel 304, extending laterally into the receiving cavity 40 and connecting to the second end of the elastic member 33. This design provides precise and short-stroke guidance for the pull rope using a simple structure, thereby improving the stability and reliability of the door 2's opening and closing.

[0035] The first door hinge 31 and the second door hinge 32 described above have the same structure, both including a first sheet metal part 10 and a second sheet metal part 20. The first sheet metal part 10 is constrained to the bottom of the side wall of the inner liner near the opening. The side of the first sheet metal part 10 is provided with a protrusion 101 arranged near the front end. The bottom of the second sheet metal part 20 is provided with a mating hole 201 that can be rotatably engaged with the protrusion 101. The front edge of the second sheet metal part 20 is located in front of the opening and is connected to the side wall of the door body 2. The rear end of the second sheet metal part 20 is provided with a hook 102 with the opening facing upward. The first ends of the first pull rope 01 and the second pull rope 02 form a hook 001 that can be hung on the hook 102. With the above structure, it is not only convenient to assemble the door hinges, but also has good assembly reliability.

[0036] In this embodiment, the upper edge of the side wall of the base 4 has a downwardly opening slot 41 near the front end, and the rear end of the first sheet metal part 10 has a downwardly extending insertion arm 500 that is inserted into the slot 41. Since the first sheet metal part 10 is subjected to a large force during the opening and closing of the door, the above structure can provide vertical support and locking for the first sheet metal part 10, thereby improving the reliability of the fit between the two sheet metal parts.

[0037] To facilitate connection and assembly, the base 4 and the plug-in arm 500 are respectively provided with first connection holes 100 for screws to pass through and lock the two together. The front part of the second sheet metal part 20 forms a connecting arm 300 that extends vertically in front of the opening. The connecting arm 300 is arranged corresponding to the inner side wall of the door body 2 and is respectively provided with second connection holes 200 for screws to pass through and lock together.

[0038] In this embodiment, the elastic element 33 is used as the middle retractable balancing element. The door hinges and pull ropes are symmetrically arranged on both sides of the elastic element 33. The force applied to the door hinge on one side of the door is used to support and balance the force applied to the door hinge on the other side of the door, so that the door body 2 is always subjected to balanced forces. This avoids the problem of unilateral wear of the hinge assembly 3, thereby improving the opening and closing reliability of the door body 2 and avoiding the occurrence of problems such as sealing of the door body 2.
