The first nozzles 21 may be preferably distributed in an array, and the first nozzles 21 and the liquid inlet pipe 24 may communicate through a pipe having a detour flat shape.

Thus, when washing is required, the washing liquid is supplied to the liquid inlet pipe 24 and the pressurized gas is supplied to the air inlet pipe 25, respectively, so that when the amount of the washing liquid is increased to a certain extent, the washing liquid is ejected upward from the first nozzle 21 and gradually filled into the washing space of the tank body 1, and a large amount of micro bubbles are formed by the air discharged from the second nozzle 22 and contacted with the washing liquid. The ultrasonic generator is arranged in the tank body 1 and is matched with the bubbles, so that the greasy dirt attached to the surface of the tableware can be better stripped.

The tank 1 has opposite first and second side walls 11, 12, and third and fourth side walls 13, 14 between the first and second side walls 11, 12, the third and fourth side walls 13, 14 also being oppositely disposed. The third side wall 13 is provided with a first guide groove 131 extending transversely near the top, and the fourth side wall 14 is provided with a second guide groove 141 corresponding to the first guide groove 131. Preferably, in the present embodiment, the third sidewall 13, the fourth sidewall 14, the first sidewall 11, and the second sidewall 12 form the rectangular parallelepiped groove body 1. The first guide groove 131 on the third side wall 13 and the second guide groove 141 on the fourth side wall 14 each extend between the first side wall 11 and the second side wall 12.

The slag scraper 34 includes a connecting rod 341 and a scraper 342, one end of the connecting rod 341 is connected to the upper end of the telescopic rod 33 through the first guide groove 131 (or the connecting rod 341 may be integrated with the telescopic rod 33), the other end of the connecting rod 341 is passed through the second guide groove 141, and a blocking piece 343 having a longitudinal dimension exceeding that of the second guide groove 141 is provided at the end located outside the second guide groove 141 to prevent the end of the connecting rod 341 from being retracted inward from the second guide groove 141, so that the connecting rod 341 stably slides between the first and second sidewalls 11 and 12 along the respective guide grooves between the third and fourth sidewalls 13 and 14. The scraping plate 342 is provided on the circumferential wall of the connection rod 341 between the third and fourth side walls 13 and 14, and has a length slightly smaller than the interval between the third and fourth side walls 13 and 14 to avoid scraping with the third and fourth side walls 13 and 14 when sliding with the connection rod 341.

When the connecting rod 31 (which can be driven manually or electrically) rotates, the sliding block 311 at one end slides in the sliding groove 321 of the swing arm 32, so as to drive the swing arm 32 to rotate around the connection position with the connecting seat 132 on the third side wall 13, thereby driving the telescopic rod 33 to synchronously move, and the slag scraper 34 moves along with the telescopic rod 33. Since the operation of the slag scraper 34 is defined by the first guide groove 131 and the second guide groove 141, the telescopic link 33 can be adjusted to be telescopic with respect to the swing arm 32 according to the distance between the slag scraper 34 and the swing arm 32 when the slag scraper 34 is moved.

The first partition plate 41 is arranged outside the first side wall 11, and the periphery of the first partition plate 41 is bent towards the first side wall 11, so that a first accommodating cavity 43 is formed between the first partition plate 41 and the first side wall 11 and is used as a foam overflow groove. The second partition plate 42 is disposed outside the second side wall 12, and the periphery of the second partition plate 42 is bent toward the second side wall 12, so that a second accommodating chamber 44 is formed between the second partition plate 42 and the second side wall 12, and serves as an overflow tank.

A foam overflow port 45 is formed in the first side wall 11 at a position corresponding to the first accommodating cavity 43, and a first slag basket 46 is arranged below the foam overflow port 131 in the first accommodating cavity 43. An overflow port 47 is formed in the second side wall 12 at a position corresponding to the second accommodating cavity 44, and a second slag basket 48 is arranged below the overflow port 47 in the second accommodating cavity 44. The first side wall 11 is provided with a first notch corresponding to the first slag basket 46, the top end part of the first slag basket 46 extends from the first notch to the inner side of the first side wall 11, the second side wall 12 is provided with a second notch corresponding to the second slag basket 48, and the top end part of the second slag basket 48 extends from the second notch to the inner side of the second side wall 12. Thus, when a large amount of residue is accumulated in the two residue baskets, the residue can be removed from the tank 1 to be cleaned. In addition, the position of the foam overflow 45 is not lower than the bottom of the blade 342 and higher than the position of the overflow 47.

During cleaning, a cleaning solution (such as water) and bubbles are introduced until the cleaning solution submerges the tableware to be cleaned in the cleaning space, oil drops and particles with the density less than that of the water are brought to the liquid level by the micro bubbles, the cleaning space is discharged through an overflow port 47 arranged at the liquid level, and the tableware cannot pass through the second slag basket 48 and is accumulated in the second slag basket 48. Meanwhile, as the detergent liquid contains the surfactant component, the foam is relatively stable and easy to accumulate, and residues which do not flow out in time are lifted to the upper part of the tableware through pushing and squeezing of the foam; thereafter, the slag scraping assembly may be operated manually or automatically, and the slag-containing foam scraped by the slag scraping assembly is discharged from the foam overflow port 45 and accumulated in the first slag basket 46 without passing through the first slag basket 46.

The structure can ensure that the lower water body in the tank body 1 is relatively cleaner, is beneficial to improving the cleaning effect, can reduce the frequency of water changing and reduces the consumption of water resources. Because the air in the bubbles occupies a very large proportion, the washing liquid can be more contacted with the surface of the tableware above the original liquid level under the condition of not adding additional water, so that the washing liquid is more water-saving compared with the ordinary soaking type washing. While the forces generated during bubble defoaming are beneficial for stripping contaminants from the surface of the cutlery.

Sponge particles, soft silica gel balls and the like or other small blocks made of materials with the density close to that of water can also be put into the washing liquid. Under the drive of water flow, the sponge particles or the pellets are contacted with the surface of the tableware, and the vegetable slag on the tableware is scraped off by friction. Alternatively, a functional gas such as ozone may be added to the air introduced into the washing tub 2 to improve the degree of cleaning of the tableware.
