[0036] The following further elaborates on the present invention in conjunction with specific embodiments.

[0037] The automatic tableware purification equipment is shown in Figure 1, including a tableware residue removal and cleaning machine 1, the tableware residue removal and cleaning machine 1 is provided with a rear tableware feeding port 101 and a front tableware output port 102. A tableware recycling module 2 is provided behind the tableware feeding port 101, and a tableware sorting module 3 is provided in front of the tableware output port 102. People place a set of tableware with food residues to be purified (not shown in the figure) on the tableware recycling module 2. The tableware recycling module 2 puts the collected tableware into the tableware residue removal and cleaning machine 1 from the tableware feeding port 101. The tableware residue removal and cleaning machine 1 automatically removes the food residues on the tableware and automatically cleans the tableware, realizing the purification of the tableware. The purified tableware is sent from the tableware output port 102 to the tableware sorting module 3, and the tableware sorting module 3 automatically sorts the tableware without manual sorting of the tableware.

[0038] A set of tableware to be purified is shown in Figure 3 , including a plate 41, a bowl 42 and a dinner plate 43. Among the three, the plate 41 is a small tableware with an outer diameter less than 100 mm, the bowl 42 is a medium-sized tableware with an outer diameter greater than 100 mm and less than 250 mm, and the dinner plate 43 is a large tableware with a length and width of 400 mm. The plate 41 and the bowl 42 are placed upright on the dinner plate 43, which is the upright state of the tableware. The tableware recycling module 2 is shown in Figure 2 , including a recycling conveyor belt 21 and a conveyor belt driving mechanism 22 for driving the recycling conveyor belt 21. A plurality of lateral partition strips 23 are arranged along the recycling conveyor belt 21. The plurality of lateral partition strips 23 laterally partition the recycling conveyor belt 21 into a plurality of conveying sections 25, and each conveying section 25 corresponds to a dinner plate 42 (see Figure 3)Equal in length, they can exactly fit into a set of tableware in the upright state. At the rear end of the recycling conveyor belt 21 of the tableware recycling module 2, there is a recycling guide block 24 with a lower front and a higher rear. The conveyor belt driving mechanism 22 is a prior art and will not be elaborated here. This device includes a controller (not shown in the figure), and the controller is electrically connected to the conveyor belt driving mechanism 22 to control the conveyor belt driving mechanism 22 to drive the recycling conveyor belt 21 to perform the following intermittent conveying actions: People place the first set of tableware in the upright state at the rear end of the recycling conveyor belt 21, and the tableware slides forward under the guidance of the recycling guide block 24 and enters the first conveying section 25 between the two lateral partition strips 23; The recycling conveyor belt 21 sends the first set of tableware forward to the tableware feeding port 101 of the tableware slag-removing and cleaning machine 1 in 3.5 seconds and exposes the second conveying section 25 behind the first conveying section 25, and then stops for 3.5 seconds; People place the second set of tableware in the upright state on the second conveying section 25 in the same way within 3.5 seconds. After 3.5 seconds, the recycling conveyor belt 21 continues to convey forward, sends the first set of tableware into the tableware cleaning machine 1 from the tableware feeding port 101 in 3.5 seconds, and at the same time sends the second set of tableware to the tableware feeding port 101 and exposes the third conveying section 25 behind the second conveying section 25, and then stops again for 3.5 seconds. People place the third set of tableware in the upright state on the third conveying section 25 within 3.5 seconds, and so on.

[0039] The tableware slag-removing and cleaning machine 1 is shown in Figure 4, including a front-back conveying chain 11 and a chain drive assembly 12 that is drivingly connected to the conveying chain 11. A plurality of tableware carrier cages 10 are arranged in the front-back direction on the conveying chain 11. The plurality of tableware carrier cages 10 are hung and installed on the links of the conveying chain 11. The conveying chain 11 serves as a conveyor belt and, together with the chain drive assembly 12, forms a conveying mechanism to convey the plurality of tableware carrier cages 10. The chain drive assembly 12 is a prior art. An impurity removal module 5, a cleaning module 6, and a drying module 7 are sequentially arranged from the back to the front between the tableware input port 101 and the tableware output port 102. These three modules 5, 6, and 7 form a tableware purification module. The conveying chain 11 includes a lower working section 118 and an upper return section 119. The working section 118 is sequentially divided into the following 5 sections from the back to the front: a tableware receiving section 111 passing through the tableware input port 101, an impurity removal section 112 passing through the impurity removal module 5, a cleaning section 113 passing through the cleaning module 6, a drying section 114 passing through the drying module 7, and a tableware dumping section 115 passing through the tableware output port 102. The controller is electrically connected to the chain drive assembly 12 and controls the chain drive assembly 12 to drive the conveying chain 11 to move, thereby successively conveying the plurality of tableware carrier cages 10 to various positions of the conveying chain 11. The tableware carrier cage 10 serves as a tableware carrier container. In its upright state, the cage opening 100 faces upward and is used to carry tableware. The conveying chain 11 first sends the tableware carrier cage 10 in the upright state to the tableware input port 101 to load tableware; then conveys the tableware carrier cage 10 from the back to the front, keeping the tableware carrier cage 10 in the upright state and successively passing through the impurity removal module 5, the cleaning module 6, and the drying module 7. These three modules 5, 6, and 7 respectively purify the tableware. Specifically, the impurity removal module 5 removes food residues from the tableware, the cleaning module 6 cleans the tableware, and the drying module 7 dries the cleaned tableware; the conveying chain 11 continues to convey the tableware carrier cage 10, sends the tableware carrier cage 10 to the tableware output port 102 to pour out the dried tableware; then conveys the tableware carrier cage 10 that has poured out the tableware to the tableware input port 101 through the return section 119 to load tableware again, and so on in a cycle. Since the tableware is loaded in the tableware carrier cage 10, the tableware carrier cage can restrict the tableware and ensure that the tableware will not fall into the impurity removal module 5, the cleaning module 6, and the drying module 7 during the processes of impurity removal, cleaning, and drying, which is beneficial for subsequent automatic sorting.

[0040] See Figure 2 , Figure 4, the controller controls the chain drive assembly 12 and the conveyor belt drive mechanism 22 to jointly drive the conveyor chain 11 and the recycling conveyor belt 21 to intermittently convey in an alternating manner as follows: the conveyor chain 11 conveys an empty tableware carrier cage 10 to the tableware feeding port 101 and then stops for 3.5 seconds. The recycling conveyor belt 21 drops the tableware into the tableware carrier cage 10 from the tableware feeding port 101 within 3.5 seconds. Then it's the turn of the recycling conveyor belt 21 to stop for 3.5 seconds, and the conveyor chain 11 sends the tableware carrier cage 10 loaded with tableware forward within 3.5 seconds and sends the next empty tableware carrier cage 10 to the tableware feeding port 101. And so on, multiple tableware carrier cages 10 pass through the tableware feeding port 101 one after another in this way and successively load multiple sets of tableware. After loading the tableware, multiple tableware carrier cages 10 pass through the slag removal module 5 one after another, pass through the cleaning module 6 one after another, and pass through the drying module 7 one after another.

[0041] See Figure 4 , a lateral support bar 131 is provided below the turning section 119 of the conveyor chain 11. Taking an empty tableware carrier cage 10 located on the turning section 119 of the conveyor chain 11 as an example, the tableware carrier cage 10 is placed horizontally with the cage opening 100 facing backward. Its upper rear corner serves as the hanging corner 105 and is hung on the link of the conveyor chain 11. Its lower front corner 106 and lower rear corner 107 are supported on the lateral support bar 131, and it moves backward under the conveyance of the conveyor chain 11. A rear arc-shaped guiding bar 1311 extending backward and downward is provided at the rear end of the lateral support bar 131. A vertical feeding guiding bar 132 is provided behind the tableware receiving section 111 of the conveyor chain 11 in the tableware slag removal and cleaning machine 1. The rear arc-shaped guiding bar 1311 and the feeding guiding bar 132 together form a feeding guiding member to guide the tableware carrier cage 10. The tableware carrier cage 10 moves from the rear end of the turning section 119 to the tableware receiving section 111. During this process: the lower rear corner 107 of the tableware carrier cage 10 first moves to the rear arc-shaped guiding bar 1311. Since the hanging corner 105 of the tableware carrier cage 10 is hung on the conveyor chain 11, the rear end of the tableware carrier cage 10 will not move downward, and the whole tableware carrier cage 10 still remains in a horizontal state; as the tableware carrier cage 10 continues to move backward, the lower front corner 106 of the tableware carrier cage 10 moves to the rear arc-shaped guiding bar 1311 and moves downward along the rear arc-shaped guiding bar 1311 under the action of gravity. Guided by the rear arc-shaped guiding bar 1311, the whole tableware carrier cage 10 rotates counterclockwise downward with the hanging corner 105 as the rotation center, passes in front of the feeding guiding bar 132, and the lower rear corner 107 of the tableware carrier cage 10 straightens backward against the feeding guiding bar 132. In this state, the tableware carrier cage 10 switches from a horizontal state to a tableware receiving state with the front low and the rear high, its cage opening 100 is inclined upward and backward, and the tableware carrier cage 10 is in an upright state for tableware to be loaded.

[0042] See Figure 4, a tableware loading guide plate 133 with a lower front and a higher rear is provided at the tableware feeding port 101. The tableware-carrying section 111 of the conveying chain 11 conveys the tableware-carrying cage 10 downward. During this process, the tableware-carrying cage 10 always maintains the state of receiving tableware under the guidance of the feeding guide bar 132. The tableware-carrying section 111 of the conveying chain 11 conveys the tableware-carrying cage 10 to the tableware feeding port 101, aligns the cage opening 100 of the tableware-carrying cage 10 with the tableware feeding port 101 and the tableware loading guide plate 133, and the lower end of the cage opening 10 is lower than the tableware loading guide plate 133. Then the conveying chain 11 pauses the conveying and allows the tableware-carrying cage 10 to stay at the tableware feeding port 101 for 3.5 seconds. See Figure 2 , Figure 4 , within 3.5 seconds, the recycling conveyor belt 21 of the tableware recycling module 2 throws the tableware into the tableware feeding port 101. The tableware thrown into the tableware feeding port 101 is guided by the tableware loading guide plate 133 and is inclined downward from the cage opening 100 and loaded into the tableware-carrying cage 10. After 3.5 seconds, the tableware-carrying section 111 of the conveying chain 11 sends the tableware-carrying cage 10 loaded with tableware downward from the tableware feeding port 101. A grating sensor 103 is provided behind the tableware feeding port 101, and the controller is electrically connected to the grating sensor 103. Some users will hold the tableware and extend it into the tableware feeding port 103 and manually load the tableware into the tableware-carrying cage 10. During this process, when the grating sensor 103 senses that there is an object at the tableware feeding port 101, it sends the sensing result to the controller, and the controller controls the chain driving assembly 12 not to drive the conveying chain 11 to move temporarily, that is, to prevent the tableware-carrying cage 10 from causing harm to the user's hand. After the user manually loads the tableware into the tableware-carrying cage 10 and then retracts the hand outside the tableware feeding port 101, in this state, when the grating sensor 103 senses that there is no longer an object at the tableware feeding port 101, the controller controls the chain driving assembly 12 to continue working and drives the conveying chain 11 to send the tableware-carrying cage 10 away from the tableware feeding port 101.

[0043] The slag removal module 5 is shown in Figure 5 , Figure 6 and Figure 8, including a slag removal tank 51 with its opening facing upwards. Inside the slag removal tank 51, there is a horizontal partition 52 which divides the interior of the slag removal tank 51 into an upper part 511 and a lower part 512. The horizontal partition 52 is provided with a slag dropping port 521 that penetrates through vertically to connect the upper part 511 of the slag removal tank 51 to the lower part 512. A residue conveying mechanism 53 is provided in the lower part 512 of the slag removal tank 51, and the residue conveying mechanism 53 is aligned with the slag dropping port 521 of the horizontal partition 52. The tableware receiving section 111 of the conveying chain 11 and the tableware carrying cage 10 moving downward along the tableware receiving section 111 are both located above the slag removal tank 51. The tableware carrying cage 10 is located above the slag dropping port 521, and the bottom and side of the tableware carrying cage 10 are both provided with slag discharging ports 109. When the tableware is loaded into the tableware carrying cage 10 in an inclined downward manner, some food residues on it will fall forward and be discharged from the slag discharging ports 109 of the tableware carrying cage 10 to the outside of the tableware carrying cage 10. Among these food residues, most will fall from the slag dropping port 521 of the horizontal partition 52 onto the residue conveying mechanism 53, be received by the residue conveying mechanism 53 and then sent away, and a small part will fall onto the horizontal partition 52. The slag removal section 112 of the conveying chain 11 includes a rear horizontal slag removal section 1121 and a front vertical slag removal section 1122. The tableware carrying cage 10 moves from the lower end of the tableware receiving section 111 of the conveying chain 11 to the horizontal slag removal section 1121. The horizontal slag removal section 1121 horizontally conveys the tableware carrying cage 10 forward, making the tableware carrying cage 10 gradually move away from the feeding guide strip 132. During this process, the entire tableware carrying cage 10 rotates downward counterclockwise around the hanging angle 105 under the action of gravity to the natural hanging state, pouring out most of the food residues on the tableware. These food residues are discharged from the slag discharging ports 109 of the tableware carrying cage 10 to the outside of the tableware carrying cage 10. Among them, most fall from the slag dropping port 521 of the horizontal partition 52 onto the residue conveying mechanism 53, be received by the residue conveying mechanism 53 and then sent away, and a small part will fall onto the horizontal partition 52. See Figure 4 , since the tableware carrying cage 10 is only hung on the conveying chain 11 by the hanging angle 105, the tableware carrying cage is not vertically upward but slightly inclined in the natural hanging state, but still in the upright state with the cage opening 100 facing upwards. The slag removal module 5 is provided with a vertical guide strip 134 at the vertical slag removal section 1122 of the conveying chain 11. The tableware carrying cage 10 moves from the horizontal slag removal section 1121 of the conveying chain 11 to the vertical slag removal section 1122. During this process, the tableware carrying cage 10 in the natural hanging state approaches and abuts against the vertical guide strip 134, and is guided by the vertical guide strip 134 to rotate counterclockwise backward to a nearly vertical state. In this state, the cage opening 100 still faces upwards and is still in the upright state.

[0044] See Figure 6, a water supply pipe 91 is connected to the lower part of the slag removal tank 51. A liquid inlet valve 911 is provided on the water supply pipe 91. A heater 92 and a bottom water level sensor 93 are provided at the bottom of the slag removal tank 51. The heater 92 is lower than the sensing height of the bottom water level sensor 93. A cleaning liquid water level sensor 94 is provided at the lower part 512 of the slag removal tank 51. The cleaning liquid water level sensor 94 is higher than the bottom water level sensor 93. The controller is electrically connected to the liquid inlet valve 911, the bottom water level sensor 93, the heater 92 and the cleaning liquid water level sensor 94. The controller controls the liquid inlet valve 911 to open, so that the water supply pipe 91 inputs clean water into the lower part 512 of the slag removal tank 51, and uses the lower part 512 of the slag removal tank 51 as a clean water storage tank to store clean water. Since the clean water storage tank belongs to the slag removal module 5, the clean water storage tank is called the slag removal tank 512 in this article. As the clean water is input into the slag removal tank 512, the water level of the slag removal tank 512 gradually rises. Since the heater 92 is lower than the sensing height of the bottom water level sensor 93, when the water level of the slag removal tank 512 rises to the sensing height of the bottom water level sensor 93, causing the bottom water level sensor 93 to generate an electrical signal, the water level of the slag removal tank 512 is already higher than the heater 92, and the controller controls the heater 92 to start working to heat the clean water in the slag removal tank 512. When the clean water level rises to the sensing height of the cleaning liquid water level sensor 94, causing the cleaning liquid water level sensor 94 to generate an electrical signal, the controller controls the liquid inlet valve 911 to close.

[0045] See Figure 5 and Figure 9, the slag removal module 5 is also a tableware slag removal spraying device. A slag removal spraying mechanism 54 is provided above the front part of the slag removal tank 51. The slag removal spraying mechanism 54 includes front and rear water baffle plates 541, 542. Between the front and rear water baffle plates 541, there are two rows of front and rear slag removal spraying pipes 543, 544. The front row of slag removal spraying pipes 543 includes 9 horizontally arranged slag removal spraying pipes 545 with the spraying ports 546 arranged vertically and facing backward. The rear row of slag removal spraying pipes 544 includes 3 horizontally arranged slag removal spraying pipes 545 with the spraying ports (not shown in the figure due to the viewing angle) arranged vertically and facing forward. The spraying ports 546 of every two adjacent horizontally arranged slag removal spraying pipes 545 are horizontally staggered from each other. The slag removal module 5 is provided with a slag removal infusion pump 55. The inlet end of the slag removal infusion pump 55 is connected to the slag removal tank 512, and the outlet end is connected to 12 horizontally arranged slag removal spraying pipes 545, pumping the clear water in the slag removal tank 512 into the horizontally arranged slag removal spraying pipes 545 to provide clear water for the horizontally arranged slag removal spraying pipes 545. The vertical slag removal section 1122 of the conveying chain 11 passes between the front and rear rows of horizontally arranged slag removal spraying pipes 543, 544. The tableware carrying cage 10 moves upward along the vertical slag removal section 1122 while remaining in the upright state and passes between the front and rear rows of horizontally arranged slag removal spraying pipes 543, 544. During this process, the slag discharge ports 109 opened at the front and rear sides of the tableware carrying cage 10 also serve as cleaning liquid spraying inlets 1091. The front and rear rows of horizontally arranged slag removal spraying pipes 543, 544 spray clear water laterally into the tableware carrying cage 10 from the cleaning liquid spraying inlets 1091, spraying onto the tableware loaded on the tableware carrying cage 10. Using clear water as the cleaning liquid, most of the remaining food residues are sprayed off the tableware, removing the food residues on the tableware in this way and realizing the purification of the tableware. The front and rear water baffle plates 541, 542 can block the water splashed onto them and prevent this water from spraying to other places. The slag removal module 5 removes the food residues on the tableware by spraying, using the impact force of the cleaning liquid sprayed onto the tableware to wash off the food residues on the tableware. Compared with immersion slag removal, spraying slag removal can more effectively remove the food residues with higher viscosity on the tableware. The vertical slag removal section 1122 and the tableware carrying cage 10 moving upward along the vertical slag removal section 1122 are located above the front part of the slag removal tank 51 and also above the front of the residue conveying mechanism 53. The water sprayed onto the tableware together with the food residues is discharged from the slag discharge port 109 of the tableware carrying cage 10 to the outside of the tableware carrying cage 10, first falling onto the cross partition 52 and then flowing along the cross partition 52 to the slag discharge port 521, washing away the food residues that have fallen onto the cross partition 52 before by the way. The water and food residues together fall from the slag discharge port 521 onto the residue conveying mechanism 53. The residue conveying mechanism 53 receives the water and food residues, filters out the food residues among them and then sends them away, and the water passes through the residue conveying mechanism 53 downward and falls back into the slag removal tank 512 (see Figure 6 ) for reuse.

[0046] See Figure 5 , Figure 6 andFigure 10 , the residue conveying mechanism 53 includes a residue conveyor belt 531 and a conveyor belt driving mechanism 532 that is drivingly connected to the residue conveyor belt 531. The conveyor belt driving mechanism 532 is a prior art. The left end 5311 of the residue conveyor belt 531 is the end, and is provided with a laterally extending portion 533 that laterally extends to the side of the slag removal tank 512. Filter holes 5312 are formed in the residue conveyor belt 531. See Figure 7 , when water and food residues fall onto the residue conveyor belt 531 together, the water and some food residues smaller than the filter holes 5312 pass through the filter holes 5312 downward and fall into the slag removal tank 512, while the food residues larger than the filter holes 5312 remain on the residue conveyor belt 531 because they cannot pass through the filter holes 5312 downward. See Figure 5 、 Figure 6 and Figure 10 , the conveyor belt driving mechanism 532 drives the residue conveyor belt 531 to convey the food residues to the left end 5311 of the residue conveyor belt 531 and pour the food residues to the side of the slag removal tank 512. A residue receiving member 534 and a cleaning liquid receiving member 535 are provided below the laterally extending portion 533 of the residue conveyor belt 531. The residue receiving member 534 is closer to the left end 5311 of the residue conveyor belt 531 than the cleaning liquid receiving member 535. The left end of the residue receiving member 534 is lower than the right end and is provided with a slag outlet 5341. The residue receiving member 534 receives the food residues that fall from the downward belt surface of the residue conveyor belt 531, and the food residues are guided by the residue receiving member 534 to flow to the left end of the residue receiving member 534 and then fall from the slag outlet 5341 at the left end of the residue receiving member 534 to the lower part of the left end 5311 of the residue conveyor belt 531. The cleaning liquid receiving member 535 leads to the slag removal tank 512, receives the cleaning liquid that falls from the downward belt surface of the residue conveyor belt 531 and discharges the received cleaning liquid to the slag removal tank 512.

[0047] See Figure 4 , the cleaning module 6 is also a tableware spraying and immersion cleaning device, including a primary spraying and immersion cleaning unit 610 and a secondary spraying and immersion cleaning unit 620. The cleaning section 113 of the conveying chain 11 is divided into a primary cleaning section 1131 and a secondary cleaning section 1132. The primary cleaning section 1131 passes through the primary spraying and immersion cleaning unit 610, and the secondary cleaning section 1132 passes through the secondary spraying and immersion cleaning unit 620. The tableware carrying cage 10 first moves forward from the slag removal section 112 of the conveying chain 11 to the primary cleaning section 1131, that is, from the slag removal module 5 to the cleaning module 6, and is sprayed and immersed by the primary spraying and immersion cleaning unit 610, and then moves forward from the primary cleaning section 1131 to the secondary cleaning section 1132 and is sprayed and immersed by the secondary spraying and immersion cleaning unit 620.

[0048] The primary spraying and immersion cleaning unit 610 See Figure 11 , includes an immersion tank 61, and the immersion tank 61 is connected to Figure 6The slag removal tank 512 is roughly the same, specifically: both are connected to a clean water supply pipe 91, and an inlet valve 911 is provided on the clean water supply pipe 91 of both. A heater 92, a bottom water level sensor 93, and a cleaning liquid water level sensor 94 are installed in the tank of both. The heater 92 is lower than the sensing height of the bottom water level sensor 93, and the cleaning liquid water level sensor 94 is higher than the bottom water level sensor 93. The controller is electrically connected to the inlet valve 911, the heater 92, the bottom water level sensor 93, and the cleaning liquid water level sensor 94. The controller controls the inlet valve 911 to open to allow the clean water supply pipe 91 to input clean water into the tank, controls the heater 92 to heat the cleaning liquid in the tank when the water level in the tank rises to the sensing height of the bottom water level sensor 93, and controls the inlet valve 911 to close when the water level in the tank rises to the sensing height of the cleaning liquid water level sensor 94. The difference between the immersion tank 61 and the slag removal tank 512 is that: the slag removal tank 512 relies entirely on the clean water supply pipe 91 to provide clean water as the cleaning liquid; in addition to relying on the clean water supply pipe 91 to provide clean water, the immersion tank 61 is also connected to an existing negative ion water generator 95. The negative ion water generator 95 used in this embodiment is provided by Kunshan Nano Green Energy Environmental Protection Technology Co., Ltd. The negative ion water generator 95 generates water containing hydroxide anions (i.e., negative ion water) by electrolyzing water. An ionized water level sensor 96 is provided between the bottom water level sensor 93 and the cleaning liquid water level sensor 94 in the immersion tank 61. The controller is electrically connected to the negative ion water generator 95 and the ionized water level sensor 96. The controller first controls the negative ion water generator 95 to generate negative ion water and input the negative ion water into the immersion tank 61. When the water level in the immersion tank 61 rises to the sensing height of the ionized water level sensor 96, causing the ionized water level sensor 96 to generate an electrical signal, the controller controls the negative ion water generator 95 to stop working and then controls the inlet valve 911 to open, allowing the clean water supply pipe 91 to input clean water into the immersion tank 61. The clean water and the negative ion water are mixed into a cleaning liquid in the immersion tank 61.

[0049] The first-stage spray immersion unit 610 is shown in Figure 12 and Figure 13, a vertically arranged spray cleaning mechanism 62 is installed above the immersion tank 61. The spray cleaning mechanism 62 includes front and rear water baffle plates 621, 622. Front and rear rows of cleaning spray pipes 623, 624 are respectively arranged at the rear sides of the front and rear water baffle plates 621, 622. The front row of cleaning spray pipes 623 includes 9 first horizontal cleaning spray pipes 625 arranged vertically with the spray nozzles 629 facing rearward. The rear row of cleaning spray pipes 624 includes 3 second horizontal cleaning spray pipes 626 with the spray nozzles 629 facing forward and 6 third horizontal cleaning spray pipes 627 with the spray nozzles 629 facing rearward. The rear water baffle plate 622 is provided with a liquid spraying port 6221. The spray nozzles 629 of the second horizontal cleaning spray pipes 626 face forward and are aligned with the liquid spraying port 6221. Therefore, the rear water baffle plate 622 does not block the spray nozzles 629 of the second horizontal cleaning spray pipes 626. The primary spray immersion unit 610 further includes a cleaning liquid infusion pump 63. The liquid inlet end of the cleaning liquid infusion pump 63 is connected to the immersion tank 61, and the liquid outlet end is connected to 18 horizontal cleaning spray pipes 625, 626, 627, pumping the cleaning liquid in the immersion tank 61 to the 18 horizontal cleaning spray pipes 625, 626, 627 to provide cleaning liquid for these 18 horizontal cleaning spray pipes 625, 626, 627. The spray nozzles 629 of every two adjacent first horizontal cleaning spray pipes 625 are horizontally staggered from each other (see Figure 9 ), and the same is true for the spray nozzles 629 of every two adjacent second horizontal cleaning spray pipes 626 and every two adjacent third horizontal spray pipes 627. The primary cleaning section 1131 of the conveying chain 11 includes front and rear vertical conveying parts 1135, 1137, and also includes a horizontal conveying part 1136 located therebetween. The rear vertical conveying part 1135 vertically extends downward from above the rear part of the immersion tank 61, passes behind the rear row of spray pipes 624, and vertically extends downward into the rear part of the immersion tank 61. The horizontal conveying part 1136 horizontally extends forward from the rear part of the immersion tank 61 to the front part of the immersion tank 61. The front vertical conveying part 1137 vertically extends upward from the front part of the immersion tank 61 and passes between the front and rear rows of cleaning spray pipes 623, 624. Vertical guiding strips 134 are arranged in front of the front and rear vertical conveying parts 1135, 1137. The vertical guiding strips 134 can guide the tableware cage 10 passing through the vertical conveying parts 1135, 1137 to keep the tableware cage 10 in a nearly vertical state and also keep the cage opening 100 facing upward in the correct position, which will not be elaborated here.

[0050] See Figure 4 and Figure 12, the tableware carrier cage 10 drives the tableware loaded thereon to move forward from the slag removal section 112 of the conveying chain 11 to the top of the rear vertical conveying section 1135 of the first-stage cleaning section 1131, located above the immersion tank 61. The rear vertical conveying section 1135 of the first-stage cleaning section 1131 conveys the tableware carrier cage 10 downward, causing the tableware carrier cage 10 to drive the tableware loaded thereon to pass behind the last row of spray pipes 624. During this process, the six third horizontal cleaning spray pipes 627 of the last row of horizontal cleaning spray pipes 624 spray the cleaning liquid mixed with negative ion water towards the tableware carrier cage 10, spraying the cleaning liquid from the cleaning liquid spray inlet 1091 of the tableware carrier cage 10 onto the tableware loaded on the tableware carrier cage 10, and spraying away the residual food residues on the tableware. In this way, the tableware on the tableware carrier cage 10 is spray-cleaned to achieve the purification of the tableware. The slag discharge port 109 of the tableware carrier cage 10 also serves as a liquid discharge port, and the cleaning liquid and food residues are discharged from the slag discharge port 109 outside the tableware carrier cage 10 and fall back into the immersion tank 61. The rear vertical conveying section 1135 of the conveying chain 11 vertically sends the tableware carrier cage 10 in an upright state from above the rear part of the immersion tank 61 downward into the rear part of the immersion tank 61, and sends the tableware loaded on the tableware carrier cage 61 from above the rear part of the immersion tank 61 downward into the rear part of the immersion tank 61 for immersion cleaning. The immersion tank 61 automatically cleans the unsprayed dead corners of the tableware by immersion, causing the residual food residues on the tableware to leave the tableware, achieving the purification of the tableware. The tableware carrier cage 10 moves from the rear vertical conveying section 1135 of the conveying chain 11 to the horizontal conveying section 1136. The horizontal conveying section 1136 horizontally conveys the tableware carrier cage 10 in an upright state from the rear part of the immersion tank 61 forward to the front part of the immersion tank 61, and sends the tableware loaded on the tableware carrier cage 10 from the rear part of the immersion tank 61 forward to the front part of the immersion tank 61. The tableware carrier cage 10 moves from the horizontal conveying section 1136 of the conveying chain 11 to the front vertical conveying section 1137. The vertical conveying section 1137 vertically sends the tableware carrier cage 10, which has been sent to the front part of the immersion tank 61, upward away from the immersion tank 61 in an upright state from the front part of the immersion tank 61, and sends the immersed tableware loaded on the tableware carrier cage 10 upward out of the immersion tank 61 from the front part of the immersion tank 61. During this process, the tableware carrier cage 10 drives the tableware loaded thereon to move upward between the front and rear rows of horizontal cleaning spray pipes 623 and 624. The front and rear rows of horizontal cleaning spray pipes 623 and 624 respectively spray the cleaning liquid onto the tableware loaded on the tableware carrier cage 10 to spray-clean the tableware that has been sent above the front part of the immersion tank 61, achieving the purification of the tableware. The cleaning liquid and the residual food residues on the tableware fall downward back into the immersion tank 61, which will not be elaborated here.This tableware cleaning device generates water containing negative ions (i.e., negative ion water) through an existing negative ion water generator 95, mixes the negative ion water with clean water to form a cleaning liquid, and uses the cleaning liquid to soak and wash the tableware instead of the existing dishwashing detergent. The water containing negative ions can remove food residues such as oil stains from the tableware. Compared with dishwashing detergent, the water generates less foam during the process of the tableware carrier cage 10 driving the tableware into the soaking pool 61 and the tableware carrier cage 10 leaving the soaking pool 61 to fish out the tableware, and the foam generated by the water will break in a short time. The foam will not accumulate in the soaking pool 61 and will not overflow outside the soaking pool 61, thus not polluting the environment. Since the spray cleaning mechanism 62 is located above the soaking pool 61 and is vertically arranged, it only needs to occupy the space above the soaking pool 61 and does not need to occupy the space on the side of the soaking pool 61.

[0051] See Figure 14, among the food residues that enter the immersion tank 61, some will float on the liquid surface of the cleaning liquid, and some will sink to the bottom of the immersion tank 61. Similarly, among the food residues that enter the slag removal tank 512, some will float and some will sink to the bottom. Floating matter discharge outlets 97 are opened at the tops of both the immersion tank 61 and the slag removal tank 512. Inside the immersion tank 61 and the slag removal tank 512, the sensing height of the floating matter discharge outlet 97 is higher than that of the cleaning liquid level sensor 94. At the beginning, the cleaning liquid in the tank will not be discharged from the floating matter discharge outlet 97. The floating matter discharge outlet 97 of the immersion tank 61 is connected to an immersion floating matter discharge pipe 98, and the immersion floating matter discharge pipe 98 leads to the slag removal tank 512, that is, the floating matter discharge outlet 97 of the immersion tank 61 discharges to the slag removal tank 512. The floating matter discharge outlet 97 of the slag removal tank 512 is connected to a slag removal floating matter discharge pipe 99, and the slag removal floating matter discharge pipe 99 leads to the outside. When the tableware carrying cage 10 is immersed in the immersion tank 61, the liquid level of the immersion tank 61 will rise above the floating matter discharge outlet 97 of the immersion tank 61. The food residues floating on the liquid surface of the cleaning liquid in the immersion tank 61 will be discharged out of the immersion tank 61 together with a part of the cleaning liquid from the floating matter discharge outlet 97 at the top of the immersion tank 61, enter the slag removal tank 512 through the immersion floating matter discharge pipe 98, causing the liquid level of the slag removal tank 512 to rise above the floating matter discharge outlet 97 of the slag removal tank 512. The food residues floating on the liquid surface of the cleaning liquid in the slag removal tank 512 will enter the slag removal floating matter discharge pipe 99 from the floating matter discharge outlet 97 at the top of the slag removal tank 512 and be discharged out of the slag removal tank 512 through the slag removal floating matter discharge pipe 99. There is less food residue in the immersion tank 61 than in the slag removal tank 512, so the cleaning liquid in the immersion tank 61 is cleaner than that in the slag removal tank 512. After these cleaning liquids are discharged from the immersion floating matter discharge pipe 98 to the slag removal tank 512, they can be reused by the slag removal module 5. The controller controls the two liquid inlet valves 911 to open for 30 seconds every 5 minutes, so that the clean water supply pipe 91 replenishes clean water to the immersion tank 61 and the slag removal tank 512, and then controls the negative ion water generator 95 to work for 1 minute, so that the negative ion water generator 95 replenishes negative ion water to the immersion tank 61. Both the immersion tank 61 and the slag removal tank 512 are provided with sediment discharge outlets at the bottom (not shown in the figure due to the viewing angle), and sediment discharge pipes 90 are connected to the sediment discharge outlets. An openable sediment discharge valve 901 is provided on the sediment discharge pipe 90. The controller is electrically connected to the two sediment discharge valves 901 and controls the two sediment discharge valves 901 to open for 10 seconds every 10 minutes, so that the food residues sinking to the bottom of the immersion tank 61 and the food residues sinking to the bottom of the slag removal tank 512 are respectively discharged from the two sediment discharge outlets into the two sediment discharge pipes 90 and discharged to the outside from the two sediment discharge pipes 90. The tableware slag removal and cleaning machine 1 can regularly discharge the food residues in the immersion tank 61 and the slag removal tank 512, keep the cleaning liquid in the immersion tank 61 and the slag removal tank 512 clean, and thus maintain good immersion and slag removal effects.

[0052] SeeFigure 4 , the secondary spray immersion cleaning unit 620 is substantially the same as the primary spray immersion cleaning unit 610, with the difference being that the primary spray immersion cleaning unit 610 relies on the clean water supply pipe 91 and the negative ion water generator 95 to supply clean water and negative ion water respectively as the cleaning liquid, while the secondary spray immersion cleaning unit 620 is the same as the slag removal tank 512, and both rely on the clean water supply pipe 91 to supply clean water as the cleaning liquid throughout the process, which will not be elaborated. The primary cleaning section 1131 and the secondary cleaning section 1132 of the conveying chain 11 are the same and will not be elaborated. Driven by the conveying chain 11, multiple tableware carrier cages 10 are successively immersed in the immersion tank 61 of the primary spray immersion cleaning unit 610 and successively receive the spray cleaning mechanism 62 of the primary spray immersion cleaning unit 61 for spraying, and then successively immersed in the immersion tank of the secondary spray immersion cleaning unit 620 and successively receive the spray cleaning mechanism of the secondary spray immersion cleaning unit 620 for spraying.

[0053] See Figure 4 , the drying module 7 includes a drying box 71 and a dryer 72 connected to the drying box 71. The drying section 114 of the conveying chain 11 is in a "U" shape, and its bottom extends into the drying box 71. The tableware carrier cage 10 moves from the cleaning section 113 of the conveying chain 11 to the drying section 114, that is, from the cleaning module 6 to the drying module 7, and sends the cleaned tableware into the drying module 7. The tableware carrier cage 10 first moves along the drying section 114 to the bottom of the drying section 114 and enters the drying box 71. The dryer 72 provides hot air to the drying box 71 to dry the cleaned tableware loaded on the tableware carrier cage 10, removing the cleaning liquid on the tableware and realizing the purification of the tableware. There are vertical guiding strips at the drying box 71, and the vertical guiding strips can guide the tableware cage 10 entering the drying box 71 to keep the tableware cage 10 in a nearly vertical state and also keep the cage opening 100 facing upward in the correct position, which will not be elaborated. The tableware carrier cage 10 continues to move along the drying section 114 and leaves the drying box 71 in the correct position, sending the dried tableware out of the drying box 71.

[0054] See Figure 4The tableware cleaning machine 1 is provided with two discharging guide shafts 134 and 135 at the rear of the tableware outlet 102, i.e., between the drying module 7 and the sorting module 3. The discharging guide shaft 134 at the front is higher than the discharging guide shaft 135 at the rear. The tableware inverting section 115 of the conveying chain 11 is divided into a vertical lifting section 1151, a front lower and rear higher inclined section 1152, and a vertical reset section 1153. The lifting section 1151 is located behind the discharging guide shaft 135 at the rear, the inclined section 1152 is located above the discharging guide shaft 134 at the front, and the reset section 1153 is located in front of the discharging guide shaft 134 at the front. The tableware carrier cage 10 is driven by the conveying chain 11 to move forward from the drying section 114 to the lifting section 1151 of the tableware pouring section 115, and then moves from the lifting section 1151 to the inclined section 1152. During this process, the discharge guide shafts 134 and 135 serve as the discharge guide parts, and the tableware carrier cage 10 is in the process of moving from the drying module 7 to the sorting module 3 (see Figure 1 ), it is first guided by the discharge guide shaft 135 at the rear, rotates clockwise toward the upper rear side with the hanging angle 105 as the rotation center, and is placed on the discharge guide shaft 134 at the front. Then, it is guided by the discharge guide shaft 134 at the front, and continues to rotate clockwise toward the upper rear side with the hanging angle 105 as the rotation center, so that the cage mouth 100 is tilted downward and aligned with the tableware output port 102, and the dried tableware is poured from the tableware output port 102 to the tableware sorting module 3 in an inverted tableware state (see Figure 1 ). After the tableware carrying cage 10 pours out the tableware, it moves from the inclined section 1152 to the reset section 1153. During this process, the tableware carrying cage 10 is no longer guided by the two material discharging guide shafts 134 and 135, and is in a natural drooping state. The front end of the transverse support bar 131 extends a front arc-shaped guide bar 1312 toward the front and bottom. The tableware carrying cage 10 moves from the reset section 1153 to the rotating section 119, and is guided by the front arc-shaped guide bar 1312. It rotates counterclockwise toward the upper front side with the hanging angle 105 as the rotation center to a horizontal state with the cage mouth 100 facing backward. Its front lower corner 106 and rear lower corner 107 are respectively supported on the transverse support bar 131, and then moves from the rotating section 119 to the tableware receiving section 111 to reload the tableware. It will not be repeated here.

[0055] Tableware sorting module 3 is a tableware sorting device, see Figure 1 , Figure 3 and Figure 15, which includes a mounting bracket 31 located at the front lower part of the tableware outlet 102. A tableware receiving member 32 with a front low and rear high structure is mounted on the mounting bracket 31. The rear end 321 of the tableware receiving member 32 is the front end and is located in front of the tableware outlet 102. The front end 322 of the tableware receiving member 32 extends forward and downward and is the rear end. A dinner plate conveyor belt 33 is provided directly below the front end 322 of the tableware receiving member 32. The left part of the dinner plate conveyor belt 33 is mounted on the left front part of the mounting bracket 31, and the right part is mounted on the right front part of the mounting bracket 31. A bowl and dish dropping opening 323 with a length and width of 380 mm is formed on the tableware receiving member 32. A left-right direction bowl and dish conveyor belt 34 is provided below the bowl and dish dropping opening 323. A guiding block 341 is provided above the front part of the bowl and dish conveyor belt 34. The bowl and dish conveyor belt 34 and the guiding block 341 are both mounted on the left rear part of the mounting bracket 31. The left end of the guiding block 341 is wider than the right end, and it can guide the items on the bowl and dish conveyor belt 34 to the rear part of the bowl and dish conveyor belt 34. A transverse lever 342 is also mounted on the guiding block 341. The distance between the lever 342 and the bowl and dish conveyor belt 34 is 60 mm, which is greater than the height of the bowl 42 but smaller than the height of the stacked bowl 42 and dish 41. The bowl and dish conveyor belt 34 conveys to the left, and its left end is the rear end. Two front-rear direction mounting shafts 351, one on the left and one on the right, are mounted on the mounting bracket 31 at the left side of the bowl and dish conveyor belt 34, that is, at the rear end of the bowl and dish conveyor belt 34. Front and rear mounting wheels 352 are respectively sleeved on the rear parts of the two mounting shafts 351. Two left-right direction screening conveyor belts 361 are respectively sleeved on the front and rear pairs of mounting wheels 352. The two screening conveyor belts 361 are arranged side by side front and rear, and a dinner plate and dish dropping opening 362 with a width of 100 mm is left between them. See Figure 16 , on which a threaded hole 353 is formed, and a locking bolt 354 is installed in the threaded hole 353. The locking bolt 354 serves as a locking mechanism, and its tail presses against the mounting shaft 351, locking the mounting wheel 352 on the mounting shaft 351 in this way; the head of the locking bolt 354 serves as an operating part and is exposed outward. See Figure 15 、 Figure 16, in the locked state, the front and rear pairs of mounting wheels 352 cannot move away from or close to each other, and the front and rear screening conveyor belts 361 also cannot move away from or close to each other. The user operates the head of the locking bolt 354 with a tool. Loosening the locking bolt 354 can release its locking of the mounting wheel 352, and then the mounting wheel 352 can move back and forth along the mounting shaft 351 to adjust the distance between the front and rear pairs of mounting wheels 352, indirectly adjusting the distance between the front and rear screening conveyor belts 361, and changing the size of the dinner plate dropping port 362 in this way. There is a left-right direction dinner bowl conveyor belt 37 on the left of the two screening conveyor belts 361, and a left-right direction dinner plate conveyor belt 38 under the two screening conveyor belts 361. The dinner bowl conveyor belt 37 is installed on the right part of the mounting frame 31. The left part of the dinner plate conveyor belt 38 is installed on the left rear part of the mounting frame 31, and the right part is installed on the right rear part of the mounting frame 31. The tableware recycling module 3 includes a driving mechanism 39 that is drivingly connected to the above conveyor belts 33, 34, 37, 38 and the screening conveyor belts 361. The driving mechanism 39 is a prior art and drives the above conveyor belts 33, 34, 37, 38 and the two screening conveyor belts 361 to convey to the left.

[0056] See Figure 1 , Figure 3 and Figure 14, the tableware is poured out from the tableware outlet 102 in an inverted manner, that is, the bowl 42, the plate 41 and the dinner plate 43 are poured out from the tableware outlet 102 in an upside-down manner with the dinner plate 43 on top, and the bowl 42 and the plate 41 below. The tableware sorting module 3, as a screening mechanism, can automatically separate the dinner plate 43, the bowl 42 and the plate. The details are as follows: After the tableware receiving member 32 receives the tableware, it conveys the tableware forward and downward. The bowl 42 and the plate 41 with an outer diameter less than 380 mm fall from the bowl and plate dropping port 323 onto the bowl and plate conveyor belt 34 during the conveying process. The dinner plate 43 with a length and width of 400 mm bypasses the bowl and plate dropping port 323 and moves onto the dinner plate conveyor belt 33 under the guidance of the tableware receiving member 32; the dinner plate conveyor belt 33 receives the dinner plate 43 sent from the front end 322 of the tableware receiving member 32 and sends the dinner plate 43 to the left. The bowl and plate conveyor belt 34 receives the bowl 42 and the plate 41 that fall from the bowl and plate dropping port 323 and sends the bowl 42 and the plate 41 to the left to two screening conveyor belts 361. During this process, the bowl 42 and the plate 41 are guided by the guide block 341 to move towards the rear of the bowl and plate conveyor belt 34; if the bowl 42 and the plate 41 are stacked together when they fall, the combined height of the two will exceed the lever 342. When passing through the lever 342, the lever 342 can push away the upper one of the stacked bowl 42 and plate 41 so that it falls onto the bowl and plate conveyor belt 34, so that the bowl 42 and the plate 41 are no longer stacked; the bowl 42 and the plate 41 are sent to the left end of the bowl and plate conveyor belt 34. Since the outer diameter of the plate 41 is less than 100 mm, it cannot be supported on the two screening conveyor belts 361 and can only fall from the dinner plate dropping port 362 between the two screening conveyor belts 361 onto the dinner plate conveyor belt 38. The dinner plate conveyor belt 38 receives the plate 41 that falls from the dinner plate dropping port 362 and then sends the plate 41 to the left. Since the outer diameter of the bowl 42 is greater than 100 mm, it can be supported upside down on the two screening conveyor belts 361 and is jointly sent to the left by the two screening conveyor belts 361 onto the soup bowl conveyor belt 37, and then is sent to the left by the soup bowl conveyor belt 37. The tableware sorting module 3 realizes the automatic sorting of tableware of different sizes through screening, without manual sorting. See Figure 15 and Figure 17 , the right part 312 of the mounting frame 31 is hinged to the left part 311. As a rotating part, it can be rotated upward and retracted to drive the right part 331 of the dinner plate conveyor belt 33, the soup bowl conveyor belt 37 and the right part 381 of the dinner plate conveyor belt 38 to rotate upward and retract, so as to facilitate the maintenance personnel to walk back and forth.

[0057] See Figure 8 , in this embodiment, the tableware carrier cage 10 is used as the tableware carrier container. The bottom and side parts of the tableware carrier cage 10 are both provided with slag discharge ports 109. In other embodiments, a tableware box with slag discharge ports only on the front and rear sides can be used instead of the tableware carrier cage 10 as the tableware carrier container, or a tableware clamping rack with the front and rear sides open can be used instead of the tableware carrier cage 10 as the tableware carrier container.

[0058] See Figure 4 , the conveying mechanism of this embodiment consists of a conveying chain 11 and a chain drive assembly 12. In other embodiments, an existing conveyor belt can be used to replace the conveying chain 11, and correspondingly, an existing belt drive assembly can be used to replace the chain drive assembly 12, and the conveying mechanism consists of a conveyor belt and a belt drive assembly. Other embodiments can use other forms of conveying mechanisms. For example, an existing manipulator can be used to clamp the tableware carrier cage 10 and then let the manipulator convey the tableware cage 10 through the tableware feeding port 101, the slag removal module 5, the cleaning module 6, the drying module 7, and the tableware output port 102 in sequence.

[0059] See Figure 5 , the slag removal module 5 of this embodiment is provided with a residue conveying mechanism 53 and a spray slag removal mechanism 54. In other embodiments, one of the mechanisms can be cancelled in the slag removal module, and the other mechanism can be retained. For example: cancel the residue conveying mechanism 53 and retain the spray slag removal mechanism 54; or cancel the spray slag removal mechanism 53 and retain the residue conveying mechanism 54.

[0060] See Figure 4 and Figure 12 , the cleaning module 6 of this embodiment includes a primary spray immersion unit 610 and a secondary spray immersion unit 620, and each spray immersion unit 610, 620 is provided with a spray mechanism 62 and an immersion tank 61. The cleaning module of other embodiments can be changed to: only one of the units is provided and the other unit is cancelled; or the spray mechanism 62 of each unit is cancelled and the immersion tank 61 is retained; or the immersion tank 61 is cancelled and the spray mechanism 62 is retained, and the cleaning liquid is directly provided for the spray mechanism 62 by the clean water supply pipe 91 and the negative ion water generator 95.

[0061] The tableware sorting module 5 of this embodiment (see Figure 14 ) automatically sorts tableware of different sizes by screening. Other embodiments can be changed to identify tableware of different shapes through an existing vision sensor, and then automatically sort the tableware by an existing manipulator.

[0062] See Figure 4 , this embodiment uses a feed guiding strip 132 and a rear arc guiding strip 1311 to form a feed guiding member to guide the tableware carrier cage 10 without loaded tableware and the tableware carrier cage 10 that has emptied the tableware. Other embodiments can use a plurality of vertically arranged guiding blocks to replace the feed guiding strip 132 and form a feed guiding member with the rear arc guiding strip 1311 to guide the tableware carrier cage 10.

[0063] See Figure 14, in this embodiment, the floating matter discharge port 97 of the immersion tank 61 is discharged to the slag removal tank 512 through the immersion floating matter discharge pipe 98. In other embodiments, the floating matter discharge port 97 and the sediment discharge port of the immersion tank 61 can be discharged to the slag removal tank 512 through pipelines.

[0064] See Figure 3 , in this embodiment, the dinner plate 43 is used as a large tableware, the bowl 42 is used as a medium-sized tableware, and the plate 41 is used as a small tableware. The three form a set of tableware. In other embodiments, other tableware can be used. For example, a spoon can be used instead of the plate 41 as the small tableware, and a set of tableware is composed of the dinner plate 43, the bowl 42 and the spoon.

[0065] See Figure 4 , in this embodiment, the tableware purification module includes a slag removal module 5 and a cleaning module 6: the slag removal module 5 removes food residues from the tableware by spraying, and can clean the tableware during the slag removal process. Therefore, the slag removal module 5 also serves as a cleaning module; the cleaning module 6 cleans the tableware by spraying and immersion, and can remove the remaining food residues on the tableware. Therefore, the cleaning module 6 also serves as a slag removal module. In other embodiments, one of the modules can be cancelled and the other module can be retained. For example, the slag removal module 5 can be cancelled and the cleaning module 6 can be retained. The cleaning module 6 also serves as a slag removal module and removes food residues from the tableware during the cleaning process. In other embodiments, the slag removal module 5 can be changed from liquid spraying slag removal to jet slag removal, that is, the slag removal module 5 removes food residues from the tableware by spraying high-pressure gas. Since the slag removal module 5 does not have a "cleaning" effect, it only serves as a slag removal module and not as a cleaning module.

[0066] See Figure 4 , in this embodiment, the tableware purification module includes a drying module 7. In other embodiments, the drying module 7 of the tableware purification module can be cancelled and an ultraviolet disinfection module can be set. The ultraviolet disinfection module is arranged in front of the cleaning module 6 and disinfects and purifies the tableware by irradiating the tableware with ultraviolet rays.

[0067] As described above, it is only the implementation manner of the present invention, and the scope of patent protection is not limited thereby. Those skilled in the art make non-substantive changes or substitutions based on the present invention, and still fall within the scope of patent protection.
