Description
Technical Field
[0001] This invention relates to the field of dishwasher technology, and more specifically to a spiral conveyor fully automatic dishwasher. Background Technology
[0002] Dishwashers are widely used in the service industry as efficient dishwashers for cleaning dishes. Their core workflow typically includes key steps such as pre-washing, multiple rinsing, drying, and conveying. By automating operations to replace manual cleaning, they not only improve cleaning efficiency but also ensure the cleanliness and hygiene of the dishes, meeting the large-scale and standardized needs for dish cleaning in different scenarios.
[0003] However, to achieve the complete cleaning process described above, existing dishwashers often require pre-washing, rinsing, and drying modules to be arranged sequentially in a straight line or plane. Each module occupies its own space, resulting in a large footprint for the dishwasher itself, making it unsuitable for space-constrained environments such as small restaurants or compact apartments. Furthermore, the traditional straight or plane conveyor structure results in a long transfer path for dishes between modules, further exacerbating the problem of the large size of the device and limiting its applicability. Summary of the Invention
[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a spiral conveyor fully automatic dishwasher, thereby solving the problems of existing dishwashers having a large footprint, complex processes, and limited applicability.

The seventh partition and the eighth partition also have transfer slots for the guide rail to pass through. The seventh partition and the eighth partition are located above the ninth partition. The partition cylinder, the sixth partition, the seventh partition, the ninth partition, and the first housing together form a drying chamber. The partition cylinder, the seventh partition, the eighth partition, the ninth partition, and the first housing together form a first relay chamber. The partition cylinder, the eighth partition, the sixth partition, the ninth partition, and the first housing together form a second relay chamber.
[0010] Optionally, the chain actuator includes several first chain sections and second chain sections that are chained together. The first chain section has two parallel chain pieces and a convex shaft connecting the two chain pieces. The top end face of the convex shaft protrudes from the chain piece and is connected to a fixing member. The second chain section has two chain heads that are rotatably connected together and chained to the convex shafts of two adjacent first chain sections.
[0011] Optionally, the fastener includes a sleeve connected to the convex shaft, a fixed shaft is fixed on the sleeve, and the fixed shaft is provided with a plurality of fixing teeth for fixing tableware.
[0012] Optionally, the guide rail has a notch, one end of which is located inside the cutlery inlet cavity and the other end is located inside the cutlery outlet cavity. The first housing is provided with a drive box located at the notch. The drive box is provided with a universal joint.

[0014] Optionally, it also includes a hot air mechanism, which connects the drying chamber to the hot air source.
[0015] The beneficial effects of this invention are as follows: This invention incorporates a partition within the first chamber, dividing it into a dish inlet chamber, a pre-washing chamber, a washing chamber, a rinsing chamber, a first intermediate chamber, a drying chamber, a second intermediate chamber, and a dish outlet chamber. A third drive source drives a chain mechanism, which in turn moves several fixed components on guide rails to carry the dishes in a spiral transport. The transported dishes enter from the dish inlet chamber, sequentially pass through the aforementioned functional chambers, and complete the entire process of loading, pre-washing, multiple rinsing, intermediate transition, drying, and unloading before exiting from the dish outlet chamber. This design overcomes the limitations of traditional dishwashers where functional modules are arranged in a straight line or plane. Through a spatial spiral layout and functional integration, the washing process, which originally required a large footprint and long inter-process transfer paths, is highly condensed within a single chamber, significantly improving space utilization, effectively reducing the overall footprint of the equipment, and achieving miniaturization and integration upgrades for the dishwasher. Its compact design allows it to flexibly adapt to space-constrained usage scenarios such as small restaurants and compact apartments, thereby expanding the applicability of dishwashers and meeting the diverse usage needs of different dishwashing areas. At the same time, the process is more seamless, reducing the risk of damage to dishes during transportation.
[0016] Meanwhile, the chain actuator of the present invention consists of a first chain section and a second chain section. The first chain section is provided with multiple protruding shafts for firmly connecting the fixing component, ensuring the reliability and stability of the connection. The second chain section is composed of two chain heads that are rotatably connected to each other. The chain heads can rotate flexibly, giving the chain actuator the ability to adjust rotation in at least two directions. This structural design can precisely adapt to the complex trajectory of the spiral guide rail, ensuring that the chain actuator runs smoothly on the spiral path, effectively transmitting driving force, avoiding jamming or loss of driving force, and thus stably driving the fixing component and the bowls it carries to move orderly along the preset path, ensuring the continuous operation of each cleaning process and helping to achieve the goal of efficient cleaning.
[0017] Furthermore, the fixing shaft of the fixing component of this invention is provided with multiple fixing teeth. These fixing teeth have good deformation capability and can be internally supported by their own deformation, or can be adapted to and firmly fixed to tableware of different sizes and shapes through deformation. This flexible fixing method can closely fit the inner wall of the bowl or tableware, forming a uniform and stable support effect. This makes it difficult for the bowl or tableware to shift, tip over, or fall during the spiral displacement along the guide rail, even when facing trajectory changes or slight tilting. This effectively ensures the stability and safety of the bowl or tableware during transportation, further improving the reliability and practicality of the equipment operation.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0038] As mentioned earlier, existing dishwashers, in order to achieve a complete cleaning process, often require pre-washing, rinsing, and drying modules to be arranged sequentially in a straight line or plane. Each module occupies independent space, resulting in a large footprint for the dishwasher itself, making it difficult to adapt to space-constrained usage scenarios such as small restaurants and compact apartments. Furthermore, the traditional straight-line or planar conveyor structure results in a long transfer path for dishes between the functional modules, further exacerbating the problem of the large size of the equipment and limiting the dishwasher's applicability.
[0039] To address this issue, the present invention provides a dishwasher that, by dividing its interior into several chambers and constructing a spiral, circulating conveyor system between the chambers, highly condenses the originally space-consuming and long-pathway cleaning process into a single unit, significantly improving space utilization, effectively reducing the overall footprint of the equipment, and achieving miniaturization and integration of the dishwasher. The present invention solves this problem through the following methods.
[0040] Example 1: Please refer to the accompanying drawings in the specification. This first embodiment provides a spiral conveyor fully automatic dishwasher, which includes, as shown in the attached drawings, a spiral conveyor fully automatic dishwasher. Figures 1 to 2 The diagram shows a first chamber 1 and a second chamber 2. The first chamber 1 is fixed to the second chamber 2. The second chamber 2 contains at least a first return water chamber, a second return water chamber, and a third return water chamber. The first and second return water chambers, as well as the second and third return water chambers, are connected by pipes. A third inlet pipe 21 and a third outlet pipe 22 are connected to the first return water chamber, and a fourth inlet pipe 23 and a fourth outlet pipe 24 are connected to the third return water chamber. The water flow from the first return water chamber to the second return water chamber, and from the second return water chamber to the third return water chamber, is unidirectional. The first chamber 1 contains several water inlets 19, all of which are connected to the second chamber (e.g., to the first, second, and third return water chambers respectively). During use, the cleaned wastewater and kitchen waste are rinsed, flow out from the water inlets 19, and enter the second chamber 2, awaiting further processing.
[0041] In this first embodiment, as Figures 2 to 7As shown, a partition 3 is provided inside the first box 1. The partition 3 has a cylinder 31 fixed in the center of the first box 1. The space around the cylinder 31 is divided into upper and lower parts by a ninth partition 310. In the lower part, the cylinder 31 has a first partition 32, a second partition 33, a third partition 34, a fourth partition 35, and a fifth partition 36 fixed along its outer wall. In the lower part, the cylinder 31 has a sixth partition 37, a seventh partition 38, and an eighth partition 39 fixed along its outer wall. Transfer slots 311 are provided on the first partition 31, the second partition 33, the third partition 34, the fourth partition 35, the fifth partition 36, the sixth partition 37, the seventh partition 38, and the eighth partition 39.
[0042] In this first embodiment, as Figure 5 As shown, the partition cylinder 31, the first partition 32, the fifth partition 36, the ninth partition 310 and the first box 1 together form the tableware inlet cavity 11. The first box 1 has an observation door at the position corresponding to the tableware inlet cavity 11. The observation door can be opened for feeding (e.g., bowls, plates, cups). The observation door has a transparent observation window, which can monitor the operation of the equipment in the first box 1 in real time.
[0043] In this first embodiment, as Figure 2 , Figure 5 , Figure 8 As shown, the partition cylinder 31, the first partition 32, the second partition 33, the ninth partition 310, and the first housing 1 together form a pre-cleaning chamber 12. An observation window is provided on the first housing 1 at the location corresponding to the pre-cleaning chamber 12. A pre-cleaning spray pipe 121 is also provided inside the pre-cleaning chamber 12. The pre-cleaning spray pipe 121 has multiple nozzles, which are aimed at the outer edges and interiors of the tableware located in the pre-cleaning chamber 12, enabling simultaneous pre-cleaning of multiple tableware to remove food waste (e.g., leftover rice, leftover dishes, etc.) from both inside and outside, completing the initial cleaning work. The bottom of the pre-cleaning spray pipe 121 extends to the outside of the first housing 1 and is connected to a first drive source 124 (e.g., a water pump) via a first water outlet pipe 123. The first drive source 124 is connected to a third return water chamber via a first water inlet pipe 122. During the pre-cleaning stage, the tableware in this stage is cleaned by the return water in the third return water chamber to rinse away any remaining food waste.
[0044] In this first embodiment, as Figures 1 to 2 , Figure 6As shown, the partition cylinder 31, the second partition 33, the third partition 34, the ninth partition 310, and the first housing 1 together form a cleaning chamber 13. An observation window is provided on the first housing 1 at the location corresponding to the cleaning chamber 13. A cleaning spray pipe 131 is also provided inside the cleaning chamber 13, and the cleaning spray pipe 131 has multiple nozzles. These nozzles are aimed at the outside and inside of the tableware located in the cleaning chamber 13, and perform all-round cleaning of the tableware for the first stage of rinsing. The bottom of the cleaning spray pipe 131 extends to the outside of the first housing 1 and is connected to a second drive source 134 (e.g., a water pump) through a second water outlet pipe 133. The second drive source 134 is connected to a second return water chamber through a second water inlet pipe 132. During the cleaning stage, the tableware in this stage is further cleaned by the return water in the second return water chamber.
[0045] In this first embodiment, as Figure 1 , Figure 6 , Figure 9 As shown, the partition cylinder 31, the third partition 34, the fourth partition 35, the ninth partition 310, and the first wall 1 together form a rinsing chamber 14. An observation window is provided on the first housing 1 at the location corresponding to the rinsing chamber 14. A rinsing spray pipe 141 is also provided inside the rinsing chamber 14. Like the cleaning spray pipe 131, the rinsing spray pipe 141 has multiple nozzles, enabling further rinsing of the tableware transferred to the rinsing chamber 14. The bottom of the rinsing spray pipe 141 passes through the housing 1 and is connected to a T-junction. The T-junction has two ports (besides connecting to the rinsing spray pipe 141). One port is connected to a clean water source, and the other is connected to the first return water chamber.
[0046] During the rinsing stage, the rinsing spray pipe 141 first uses the water from the first return water chamber to further clean the tableware. After cleaning, it uses clean water for a final rinse.
[0047] In this first embodiment, as Figures 3 to 7 As shown, the partition cylinder 31, the fourth partition plate 35, the fifth partition plate 36, the ninth partition plate 310, and the first box body 1 together form the tableware outlet cavity 18; the partition cylinder 31, the sixth partition plate 37, the seventh partition plate 38, the ninth partition plate 310, and the first box body 1 together form the drying chamber 16; the partition cylinder 31, the seventh partition plate 38, the eighth partition plate 39, the ninth partition plate 310, and the first box body 1 together form the first relay chamber 15; the partition cylinder 32, the eighth partition plate 39, the sixth partition plate 37, the ninth partition plate 310, and the first box body 1 together form the second relay chamber 17.
[0048] The first relay chamber 15 isolates the rinsing chamber 14 from the drying chamber 16, serving a draining function. The second relay chamber 17 isolates the drying chamber 16 from the tableware outlet chamber 18, serving to cool the tableware and prevent it from becoming too hot, thus avoiding burns when handling it. The first and second relay chambers 15 are optional. Alternatively, a third relay chamber can be added between the tableware inlet chamber 11 and the tableware outlet chamber 18 by installing an additional partition for isolation.
[0049] The first housing 1 has observation windows for the drying chamber 16 and the tableware outlet 18 respectively. The drying chamber 16 is also equipped with a hot air mechanism 161, which extends out of the drying chamber 16 and is connected to an external hot air mechanism. The hot air mechanism continuously blows hot air into the drying chamber 16 through the hot air mechanism 161 (the first housing 1 is also equipped with an exhaust port), thereby drying the tableware located in the drying chamber 16.
[0050] In this first embodiment, as Figures 1 to 8 , Figures 8 to 14 , Figures 16 to 17 As shown, a spiral-shaped guide rail 4 is provided inside the first housing 1. This guide rail 4 is fixed inside the first housing 1 and, starting from the tableware inlet cavity 11, passes through each transfer slot 311, sequentially through the pre-cleaning chamber 12, cleaning chamber 13, rinsing chamber 14, first relay chamber 15, drying chamber 16, and second relay chamber 17, finally reaching the tableware outlet cavity 18, forming a spiral movement line for conveying the tableware (e.g., ...). Figure 16 As shown, there is a gap 41 between the guide rail 4 located in the cutlery inlet cavity 11 and the guide rail 4 located in the cutlery outlet cavity 18, and the functions of loading and unloading, driving and other functions are realized through the gap 41.
[0051] Meanwhile, several fixing parts 5 are slidably connected on the guide rail 4. The fixing parts 5 are used to fix the tableware (for example, to fix the bowl upside down on it). The guide rail 4 is also provided with a chain actuator 6 that links these fixing parts 5 together. The part of the first box 1 located in the tableware inlet cavity 11 is also provided with a drive box 64. A universal joint 67 is provided in the drive box 64. A sprocket 63 is rotatably connected to the drive box 64. The sprocket 63 and the chain actuator 6 are chain-engaged together. The sprocket 63 has a certain inclination relative to the drive box 64 to meet the connection with the chain actuator 6. Meanwhile, one end of the universal joint 67 is connected to the sprocket 63, and the other end passes through the drive box 64 and the first box 1 and is fixedly connected to the drive shaft 66. The drive shaft 66 is connected to the third drive source 65 (e.g., a motor). The third drive source 65 is fixed to the bottom of the first box 1. Through the third drive source 65, the sprocket 63 is driven to rotate via the universal joint 67. The sprocket 63 drives the chain drive 6 to rotate, which in turn drives the fixed part 5 to move along the guide rail 4, thereby realizing the transfer of tableware.
[0052] Therefore, in the specific implementation of this embodiment, the operator places the tableware onto the fixing member 5 inside the tableware inlet cavity 11. The fixing member 5 then moves the tableware through the pre-cleaning chamber 12 for pre-cleaning, the cleaning chamber 13, the rinsing chamber 14 for cleaning, the first transit chamber 15 for transfer, the drying chamber 16 for drying, the second transit chamber 17 for transfer, and finally into the tableware outlet cavity 18, where the operator removes the tableware. This completes the entire cleaning process.
[0053] Example 2: Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions therein, the present invention also provides an embodiment two. For example... Figures 11 to 12 , Figure 17 As shown, in this second embodiment, the chain actuator 6 is composed of several first chain portions 61 and second chain portions 62 that are interconnected. The first chain section 61 has two parallel chain pieces and a convex shaft connecting the two chain pieces. The top end face of the convex shaft protrudes from the chain piece and is connected to a fixing member 5. The second chain section 62 has two chain heads that are rotatably connected together and are chain-connected to the convex shafts of two adjacent first chain sections 61.
[0054] A chain opening is formed between the two convex shafts and the chain piece to cooperate with the drive of the sprocket 63. The bottom of the convex shaft is also provided with a first slider, which is slidably connected to the guide rail 4 (the guide rail 4 has a first groove at the position corresponding to the slider).
[0055] The second chain section 62 consists of two chain heads rotatably connected together. These two chain heads can rotate infinitely relative to each other, and the connecting part of these two chain heads has deformation capability. This allows the chain actuators 6 to have rotational capability in at least two directions when connected together, enabling them to better adapt to the spiral shape of the guide rail 4, and thus more accurately drive the fixing part 5 and the tableware on it to perform the transfer work.
[0056] Example 3: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, the present invention also provides Embodiment Three. For example... Figure 12 , Figure 17As shown, in this third embodiment, the fixing member 5 includes a sleeve 53 fixed on the convex shaft of the first chain 61 (the sleeve 53 is a flexible mechanism that can deform to adapt to partial displacement during transport). A fixing shaft 51 is fixed on the sleeve 53 (the fixing shaft 51 is provided with a second slider, and is slidably connected to the second groove opened on the guide rail 4 through the second slider to achieve a sliding connection with the guide rail 4). Several fixing teeth 52 are arranged oppositely on the fixing shaft 51. The fixing teeth 52 are made of elastomeric modified plastic or engineering plastic, so that they can deform slightly while having a certain rigidity, and thus can adapt to tableware of different sizes and shapes. When in use, the tableware is upside down on the fixing teeth 52, and the fixing teeth 52 support the tableware inside, thereby fixing the tableware so that the tableware will not fall off even if it is tilted during transport.
[0057] Therefore, in summary, the technical solutions provided by the present invention and its embodiments have advantages over the prior art, including but not limited to the following: This invention incorporates a partition 3 within the first housing 1, dividing it into a tableware inlet chamber 11, a pre-washing chamber 12, a washing chamber 13, a rinsing chamber 14, a first relay chamber 15, a drying chamber 16, a second relay chamber 17, and a tableware outlet chamber 18. A third drive source 65 drives a chain actuator 6, which in turn drives several fixed components 5 to spirally transport the tableware along guide rails 4. The transported tableware enters from the tableware inlet chamber 11, sequentially passes through the aforementioned functional chambers, and completes the entire process of loading, pre-washing, multiple rinsing stages, relay transitions, drying, and unloading before exiting from the tableware outlet chamber 18. This design overcomes the limitations of traditional dishwashers where functional modules are arranged in a straight line or plane. Through a spatial spiral layout and functional integration, the washing process, which originally occupied a large area and involved long inter-process transfer paths, is highly condensed within a single housing, significantly improving space utilization, effectively reducing the overall footprint of the equipment, and achieving miniaturization and integration upgrades for the dishwasher. Its compact design allows it to flexibly adapt to space-constrained usage scenarios such as small restaurants and compact apartments, thereby expanding the applicability of dishwashers and meeting the diverse usage needs of different dishwashing areas. At the same time, the process is more seamless, reducing the risk of damage to dishes during transportation.
[0058] Meanwhile, the chain actuator 6 of the present invention consists of a first chain portion 61 and a second chain portion 62. The first chain portion 61 is provided with multiple protruding shafts for securely connecting the fixing member 5, ensuring the reliability and stability of the connection. The second chain portion 62 is composed of two chain heads that are rotatably connected to each other. The chain heads can rotate flexibly, so that the chain actuator 6 as a whole has the ability to adjust rotation in at least two directions. This structural design can accurately adapt to the complex trajectory of the spiral-shaped guide rail 4, ensuring that the chain actuator 6 runs smoothly on the spiral path, effectively transmitting driving force, avoiding jamming or loss of driving force, and thus stably driving the fixing member 5 and the bowls it carries to move in an orderly manner along the preset path, ensuring the continuous operation of each cleaning process and helping to achieve the goal of efficient cleaning.
[0059] Furthermore, the fixing shaft 51 of the fixing member 5 of the present invention is provided with multiple fixing teeth 52. These fixing teeth 52 have good deformation capability and can be internally supported by their own deformation, or can be adapted to and firmly fixed to tableware of different sizes and shapes through deformation. This flexible fixing method can closely fit the inner wall of the bowl or tableware, forming a uniform and stable support effect. This makes it difficult for the bowl or tableware to shift, tip over, or fall during the spiral displacement along the guide rail 4, even if it faces trajectory changes or slight tilting. This effectively ensures the stability and safety of the bowl or tableware during transportation, and further improves the reliability and practicality of the equipment operation.
