[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0027] To address the problems in the background technology, this utility model proposes a dishwasher bubble cleaning tank, comprising:

[0028] Rack 1;

[0029] The cleaning tank 2 is located inside the frame 1 and is used to contain the cleaning liquid;

[0030] The transmission mechanism 3, located inside the washing tank 2, is used to move the tableware horizontally from the inlet side to the outlet side of the washing tank 2; and

[0031] The bubble cleaning component 4 is located in the middle area of ​​the cleaning pool 2 and is used to release bubbles into the pool to clean the surface of the tableware.

[0032] Combined with reference Figures 1 to 3 As shown, in this embodiment, the frame 1 serves as the overall support frame, its surface is treated with anti-rust electrophoresis, and its bottom is equipped with adjustable support feet to adapt to uneven ground conditions. The cleaning tank 2 is housed within the frame 1 and is primarily used to hold the cleaning liquid. The cleaning tank 2 is made of corrosion-resistant and high-temperature-resistant materials to ensure stable operation over extended periods during the cleaning process. The cleaning tank 2 is generally rectangular or arc-shaped to accommodate different tableware placement needs and has a large capacity to hold sufficient cleaning liquid, which can be pure water or a liquid mixed with disinfectants, food-grade surfactants, etc. A drainage system can be optionally provided at the bottom or on the side wall of the cleaning tank 2 to facilitate the smooth discharge of cleaning liquid after cleaning and ensure the tank remains clean.

[0033] The conveying mechanism 3 is located inside the washing tank 2, between the inlet and outlet sides. This mechanism 3 moves the tableware horizontally from the inlet to the outlet within the washing tank 2, ensuring that the tableware is evenly exposed to the cleaning liquid and receives bubble cleaning. The conveying mechanism 3 includes components such as an electric drive unit, chain, or rollers, which can smoothly and efficiently move the tableware and control its residence time above the bubble cleaning assembly 4, such as selectively allowing it to remain for three minutes or two minutes for cleaning.

[0034] The bubble cleaning component 4 is located in the central area of ​​the cleaning tank 2. Its main function is to release bubbles into the cleaning tank, using the collision and friction of the bubbles to clean the surface of the tableware. This bubble cleaning component 4 typically consists of a bubble generator, air ducts, and jet nozzles. The bubble generator produces a large number of tiny bubbles by mixing air or other gases with the cleaning liquid. These bubbles rise within the cleaning tank and contact the surface of the tableware to achieve a cleaning effect. Specifically, the bubble cleaning component 4 generates a dense cluster of bubbles that perform cleaning during the bubbling process. The micro-jet streams generated by the bursting bubbles directly impact the oil stains, surface adsorption removes contaminants, and the turbulence effect enhances liquid disturbance, achieving a rapid cleaning effect.

[0035] In one possible implementation, the cleaning tank 2 has ramps 21 on both sides and a horizontal section 22 connecting the bottoms of the two ramps 21 in the middle, wherein the bubble cleaning assembly 4 is disposed in the area below the horizontal section 22.

[0036] Combined with reference Figure 1 As shown, in this embodiment, the cleaning tank 2 adopts a V-shaped cross-section structure, with inclined slopes 21 on both sides sloping towards the center line of the tank. The inclined slopes 21 form an angle of 35°-40° with the horizontal plane to accelerate the sliding of dirt. A horizontal section 22 extends between the bottom ends of the two inclined slopes 21. This horizontal section 22 is precision welded from a stainless steel plate and its surface is polished to reduce frictional resistance. The bubble cleaning assembly 4 is positioned directly below the horizontal section 22. This arrangement allows the bubble cluster to rise vertically and directly impact the concave area of ​​the dish, coordinating with the dirt guided by the inclined slopes 21 to the drain outlet of the horizontal section 22, achieving synergistic optimization of cleaning efficiency and drainage performance.

[0037] In one possible implementation, the bubble cleaning assembly 4 includes an aeration pipe group 41 located below the cleaning tank 2, an air pump 42 connected to the aeration pipe group 41, and a plurality of bubble nozzles 43 evenly distributed on the aeration pipe group 41. Each bubble nozzle 43 extends upward from the aeration pipe group 41 and penetrates the bottom surface of the cleaning tank 2, with its nozzle located inside the cleaning tank 2 and facing the movement path of the tableware.

[0038] Combined with reference Figure 1 and Figure 2 As shown, in this embodiment, the aeration pipe assembly 41 is horizontally arranged at the bottom of the cleaning tank 2, that is, below the horizontal section 22. A vortex air pump 42 is connected via a pipe to provide an air source, allowing air to enter the cleaning tank 2 through the aeration pipe assembly 41. Aeration holes are evenly spaced on the aeration pipe assembly 41, and each aeration hole is welded with a brass bubble nozzle 43, which vertically penetrates the bottom plate of the cleaning tank 2 and extends into the tank, forming a pre-impact zone directly opposite the tableware movement path. This allows the bubble flow to diffuse and cover the conveyor belt, effectively improving the removal rate of residual oil.

[0039] In one possible implementation, a heating component 5 is provided inside the cleaning tank 2. The heating component 5 includes multiple heating tubes 51 arranged in parallel along the length of the cleaning tank 2 and a temperature sensor located inside the cleaning tank 2.

[0040] Combined with reference Figure 1 As shown, in this embodiment, multiple heating tubes 51 are horizontally embedded inside the horizontal part 22 along the width direction of the cleaning tank body 2. The temperature sensor is installed at the center point of the side wall height of the cleaning tank body 2. The heating power is dynamically adjusted by the PID controller to maintain the optimal cleaning temperature and reduce the viscosity of the grease.

[0041] In one possible implementation, the transmission mechanism 3 includes:

[0042] Two drive chains 31 are arranged in parallel on both sides of the cleaning tank 2 and along the length of the cleaning tank 2.

[0043] Multiple chain plates 32 are laterally connected between two drive chains 31 to form a bearing surface; and

[0044] The drive unit 33 is connected to the transmission chain 31.

[0045] Combined with reference Figure 2 and Figure 3 As shown, in this embodiment, two roller drive chains 31 are arranged parallel to each other on both sides of the washing tank 2 and along the length of the washing tank 2. Multiple chain plates 32 are laterally straddled between the two drive chains 31 to form a stable bearing surface for supporting and carrying tableware. These chain plates 32 are driven by the movement of the chains to ensure the smooth movement of tableware within the washing tank 2. The drive chains 31 are connected to the drive unit 33, which, through the coordinated action of a servo motor system, a high-precision encoder, and a PLC control module, realizes intelligent retention control of tableware in the bubble cleaning zone. Specifically, the transmission speed is automatically adjusted according to the preset cleaning mode (e.g., standard mode 1 minute, heavy oil mode 3 minutes), and in conjunction with the sprocket positioning sensor and optical detection device, the tableware is precisely positioned above the bubble cleaning assembly 4.

[0046] In one possible implementation, a dish picker assembly 6 is provided between each of the chain plates 32, which includes multiple sets of staggered picker units 61. Each picker unit 61 includes a support base 611 connecting two adjacent chain plates 32, a limiting part 612 provided on one side of the support base 611, and a pushing part 613 provided on the other side. A placement groove 614 is formed between the pushing part 613 and the limiting part 612 for placing tableware.

[0047] Combined with reference Figure 3 As shown, in this embodiment, each set of toothed units 61 is staggered and fixed at the joint of adjacent chain plates 32. Each set of toothed units 61 consists of a supporting base 611 connecting two adjacent chain plates 32, a limiting part 612 disposed on one side of the supporting base 611, and a pushing part 613 disposed on the other side of the supporting base 611. The supporting base 611 is a stainless steel plate that horizontally spans the gap between the two chain plates 32. The limiting part 612 is an arc-shaped silicone baffle with a bending radius and its concave surface facing the inlet side, while the pushing part 613 has its top inclined towards the outlet side, forming a placement groove 614 with the limiting part 612 at intervals, effectively preventing the tableware from drifting under the impact of air bubbles. Furthermore, the top of the pusher 613 is higher than the limiting part 612 by a certain height to form a height difference. A guide is provided on the outlet side corresponding to the position of the pusher 613. When the tableware is moved to the outlet area after being cleaned by bubbles, the inclined surface of the pusher 613 and the guide plate form a continuous slide, allowing the tableware to slide into the next station.
