Description

Technical Field

[0001] The utility model relates to the technical field of tableware washing, in particular to tableware washing equipment without overflowing foam. Background Art

[0002] The tableware washing equipment includes a washing tank and a conveyor belt. The conveyor belt conveys the tableware with food residues into the washing tank for washing, so that the food residues on the tableware are separated from the tableware. The washed tableware needs to be manually removed. Conventional tableware cleaning equipment uses detergent as a cleaning liquid. A large amount of foam is generated during the process of the tableware entering the washing tank and being removed from the washing tank. These foams accumulate in the washing tank and overflow outside the washing tank, polluting the environment. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a tableware washing device without overflowing foam. When the tableware is washed using the tableware washing device, less foam is generated in the process of the tableware entering the washing tank and being taken out of the washing tank, and the foam will not overflow outside the washing tank.

[0004] In order to solve the above technical problems, the utility model provides a tableware washing device without overflowing foam, including a washing pool and a conveying mechanism for conveying tableware into the washing pool for washing, and a negative ion water generator is provided to provide negative ion water cleaning liquid for the washing pool.

[0005] Furthermore, the conveying mechanism delivers the washed tableware out of the washing tank.

[0006] Furthermore, the conveying mechanism includes a conveyor belt, on which a tableware carrying container for loading tableware is installed. The conveyor belt delivers the tableware loaded on the container into the immersion tank, specifically, delivers the tableware carrying container 1 loaded with tableware downward into the immersion tank.

[0007] Furthermore, the conveyor belt sends the tableware carrying container immersed in the soaking tank upward away from the soaking tank, thereby sending the tableware loaded on the container out of the soaking tank.

[0008] Furthermore, the conveyor belt is specifically a conveyor chain; the tableware carrying container is a tableware carrying cage, and its cage mouth faces upwards for tableware to be placed in the upright state; the conveyor belt sends the tableware carrying cage vertically downward into the immersion tank in the upright state, and sends the tableware carrying cage immersed in the immersion tank vertically upward out of the immersion tank from the front of the immersion tank in this state.

[0009] Furthermore, a spray mechanism is provided during the transportation of the tableware to spray and clean the tableware.

[0010] Furthermore, when the tableware passes over the immersion tank during transportation, the spray mechanism sprays cleaning liquid toward the tableware transported to the immersion tank, thereby spraying and cleaning the tableware, and the cleaning liquid sprayed onto the tableware falls back into the immersion tank.

[0011] Furthermore, an infusion pump is provided to extract cleaning liquid from the immersion tank and pump it to the spray mechanism to provide the cleaning liquid to the spray mechanism.

[0012] Furthermore, a clean water supply pipe is provided for supplying water to the immersion pool, a liquid inlet valve is provided on the clean water supply pipe, and two water level sensors with different heights are provided in the immersion pool; a controller is included, and the controller is electrically connected to the negative ion water generator and the liquid inlet valve, and is also electrically connected to the two water level sensors.

[0013] Furthermore, there are two immersion pools, one in the front and the other in the rear. The negative ion water generator provides negative ion water cleaning liquid for the rear immersion pool. A clean water supply pipe is provided to provide clean water cleaning liquid for the front immersion pool. The conveying mechanism conveys tableware from the back to the front, first sending the tableware into the rear immersion pool and then into the front immersion pool for immersion.

[0014] The tableware washing device provided by the utility model generates water containing negative ions (i.e., negative ion water) through an existing ion water generator, and uses the negative ion water instead of detergent as a cleaning liquid to wash the tableware. The water containing negative ions can remove food residues such as grease from the tableware. Compared with detergent, water generates less foam when the tableware is put into the immersion tank and the tableware is taken out of the immersion tank, and the foam generated by the water will burst in a short time. The foam will not accumulate in the immersion tank, and will not overflow outside the immersion tank, thereby not polluting the environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below in conjunction with specific implementation methods.

[0023] Automatic tableware washing equipment Figure 1 , with a tableware inlet 101 at the rear and a tableware outlet 102 at the front. People put a set of tableware with food residues to be cleaned (not shown in the figure) into the automatic tableware washing device from the tableware inlet 101, and the automatic tableware washing device automatically washes and dries the tableware, and the dried tableware is sent out from the tableware outlet 102.

[0024] Automatic tableware washing equipment Figure 2 , including a conveying chain 11 in the front-to-back direction and a chain driving assembly 12 driving and connecting the conveying chain 11, a plurality of tableware carrying cages 10 arranged front and back along the conveying chain 11 are installed on the conveying chain 11, and the plurality of tableware carrying cages 10 are hung and installed on the chain links of the conveying chain 11. The conveying chain 11 is used as a conveyor belt, and forms a conveying mechanism with the chain driving assembly 12 to convey the plurality of tableware carrying cages 10. The chain driving assembly 12 is a prior art. A washing module 6 and a drying module 7 are sequentially arranged from back to front between the tableware delivery port 101 and the tableware delivery port 102. The conveyor chain 11 includes a lower working section 118 and an upper rotating section 119. The working section 118 is divided into the following five sections from the back to the front: a tableware receiving section 111 passing through the tableware delivery port 101, a carrying section 112, 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 delivery port 102. The tableware automatic cleaning device includes a controller, which is electrically connected to the chain drive assembly 12, and controls the chain drive assembly 12 to drive the conveyor chain 11 to move so as to successively transport multiple tableware carrying cages 10 to various locations of the conveyor chain 11. The tableware carrying cage 10 is used as a tableware carrying container, and its cage mouth 100 faces upward in the upright state, and is used to carry tableware. The conveyor chain 11 first delivers the tableware carrier cage 10 in an upright state to the tableware delivery port 101 to load the tableware; then the tableware carrier cage 10 is transported from the back to the front so that the tableware carrier cage 10 remains in an upright state and passes through the cleaning module 6 and the drying module 7 in sequence, the cleaning module 6 cleans the tableware, and the drying module 7 dries the cleaned tableware; the conveyor chain 11 continues to transport the tableware carrier cage 10, and delivers the tableware carrier cage 10 to the tableware delivery port 102 to pour out the dried tableware; then the tableware carrier cage 10 that has poured out the tableware is transported to the tableware delivery port 101 through the rotating section 119 to load the tableware again, and the cycle repeats. Since the tableware is loaded in the tableware carrier cage 10, the tableware carrier cage can restrict the tableware, ensuring that the tableware will not be scattered into the cleaning module 6 and the drying module 7 during the cleaning and drying process.

[0025] See Figure 2 , the controller controls the chain drive assembly 12 to drive the conveyor chain 11 to perform intermittent conveying as follows: the conveyor chain 11 conveys a tableware carrier cage 10 that is not loaded with tableware to the tableware delivery port 101 and then stops for 3.5 seconds, people put tableware into the tableware carrier cage 10 from the tableware delivery port 101 within 3.5 seconds, and then the conveyor chain 11 sends the tableware carrier cage 10 loaded with tableware forward within 3.5 seconds and sends the next tableware carrier cage 10 that is not loaded with tableware to the tableware delivery port 101, and so on, multiple tableware carrier cages 10 pass through the tableware delivery port 101 in this way and load multiple sets of tableware in succession. After loading the tableware, the multiple tableware carrier cages 10 pass through the cleaning module 6 and the drying module 7 in succession.

[0026] See Figure 2 , a transverse support bar 131 is provided below the rotating section 119 of the conveying chain 11. Taking a tableware carrier cage 10 without tableware on the rotating section 119 of the conveying chain 11 as an example, the tableware carrier cage 10 is placed horizontally with the cage opening 100 facing backwards, and its rear upper corner is used as a hanging corner 105, which is hung on the chain link of the conveying chain 11, and its front lower corner 106 and rear lower corner 107 are supported on the transverse support bar 131, and it moves backward under the conveying of the conveying chain 11. The rear end of the transverse support bar 131 is provided with a rear arc-shaped guide bar 1311 extending backward and downward, and the automatic tableware washing device is provided with a vertical feeding guide bar 132 behind the tableware receiving section 111 of the conveying chain 11. The tableware carrying cage 10 moves from the rear end of the rotating section 119 to the tableware receiving section 111. During this process: the front lower corner 106 of the tableware carrying cage 10 moves to the rear arc-shaped guide strip 1311 and moves downward along the arc-shaped guide strip 1311 under the action of gravity. Guided by the rear arc-shaped guide strip 1311, the tableware carrying cage 10 as a whole rotates counterclockwise downward with the hanging angle 105 as the rotation center, and the rear lower corner 107 of the tableware carrying cage 10 stands up backward to resist the feeding guide strip 132. In this state, the tableware carrying cage 10 switches from a horizontal state to a tableware receiving state with a low front and a high rear, and its cage mouth 100 is tilted toward the upper rear, and the tableware carrying cage 10 is in an upright state, which can be used for tableware loading.

[0027] See Figure 2 A cutlery guide plate 133 with a lower front and a higher back is provided at the cutlery delivery port 101. The cutlery receiving section 111 of the conveyor chain 11 transports the cutlery carrier cage 10 downwards. During this process, the cutlery carrier cage 10 always remains in a cutlery receiving state under the guidance of the feed guide bar 132. The cutlery receiving section 111 of the conveyor chain 11 transports the cutlery carrier cage 10 to the cutlery delivery port 101, so that the cage mouth 100 of the cutlery carrier cage 10 is aligned with the cutlery delivery port 101 and the cutlery loading guide plate 133, and the lower end of the cage mouth 10 is lower than the cutlery loading guide plate 133, and then the conveyor chain 11 stops conveying, allowing the cutlery carrier cage 10 to stay at the cutlery delivery port 101 for 3.5 seconds. Figure 2 People put tableware into the tableware inlet 101 within 3.5 seconds, and the tableware put into the tableware inlet 101 is guided by the tableware guide plate 133 to be loaded into the tableware carrying cage 10 from the cage opening 100. The tableware receiving section 111 of the conveying chain 11 sends the tableware carrying cage 10 loaded with tableware downward from the tableware inlet 101 after 3.5 seconds.

[0028] See Figure 2 The cleaning module 6 is also a tableware spraying and immersing device, including a primary spraying and immersing unit 610 and a secondary spraying and immersing 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 immersing unit 610, and the secondary cleaning section 1132 passes through the secondary spraying and immersing unit 620. The tableware carrying cage 10 first moves forward from the carrying section 112 of the conveying chain 11 to the primary cleaning section 1131, and receives spraying and immersion from the primary spraying and immersion unit 610, and then moves forward from the primary cleaning section 1131 to the secondary cleaning section 1132, and receives spraying and immersion from the secondary spraying and immersion unit 620.

[0029] First-stage spray leaching unit 610 Figure 4, including a leaching pool 61, the leaching pool 61 is connected to a clean water supply pipe 91, the clean water supply pipe 91 is provided with a liquid inlet valve 911, the leaching pool 61 is installed with a heater 92, a bottom water level sensor 93 and a cleaning liquid water level sensor 94, the sensing height of the bottom water level sensor 93 is higher than the heater 92, and the sensing height of 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 heater 92, the bottom water level sensor 93 and the cleaning liquid water level sensor 94. The leaching pool 61 is also connected to an existing negative ion water generator 95, and the present embodiment adopts the negative ion water generator 95 provided by Kunshan Nano Green Energy Environmental Protection Technology Co., Ltd., and the negative ion water generator 95 generates water containing hydroxide negative ions (i.e., negative ion water) by electrolyzing water, and the leaching pool 61 is provided with an ion water level sensor 96 between the bottom water level sensor 93 and the cleaning liquid water level sensor 94, and the controller is electrically connected to the negative ion water generator 95 and the ion 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. The water level of the immersion tank 61 rises slowly. When the water level rises to the sensing height of the bottom water level sensor 93 so that the bottom water level sensor 93 generates an electrical signal, the controller controls the heater 92 to heat the cleaning liquid in the tank. When the water level of the immersion tank 61 rises to the sensing height of the ion water level sensor 96 so that the ion water level sensor 96 generates an electrical signal, the controller controls the negative ion water generator 95 to stop working and then controls the liquid inlet valve 911 to open, so that the clean water supply pipe 91 inputs clean water into the tank. The controller controls the liquid inlet valve 911 to close when the water level in the immersion tank 61 rises to the sensing height of the cleaning liquid level sensor 94.

[0030] First-stage spray leaching unit 610 Figure 4 , Figure 5 and Figure 6A vertically arranged spray cleaning mechanism 62 is installed above the immersion tank 61. The spray cleaning mechanism 62 includes two front and rear water baffles 621 and 622, and two front and rear rows of cleaning spray pipes 623 and 624 are respectively arranged on the rear sides of the front and rear water baffles 621 and 622. The front row of cleaning spray pipes 623 includes a first horizontal cleaning spray pipe 625 with 9 spray ports 629 arranged vertically and facing backwards, and the rear row of cleaning spray pipes 624 includes a second horizontal cleaning spray pipe 626 with 3 spray ports 629 arranged vertically and facing forwards, and a third horizontal cleaning spray pipe 627 with 6 spray ports 629 facing backwards. The rear water baffle 622 is provided with a liquid spray port 6221, and the spray port 629 of the second transverse cleaning spray pipe 626 is aligned forward with the liquid spray port 6221, so the rear water baffle 622 will not block the spray port 629 of the second transverse cleaning spray pipe 626. The primary spray immersion washing unit 610 also includes a cleaning infusion pump 63, the liquid inlet end of the cleaning infusion pump 63 is connected to the immersion washing pool 61, and the liquid outlet end is connected to 18 transverse cleaning spray pipes 625, 626, 627, and the cleaning liquid in the immersion washing pool 61 is pumped to the 18 transverse cleaning spray pipes 625, 626, 627 to provide cleaning liquid for these 18 transverse cleaning spray pipes 625, 626, 627. The spray ports 629 of each two adjacent first transverse cleaning spray pipes 625 are laterally staggered from each other (see Figure 7 ), the same is true for the spray ports 629 of every two adjacent second transverse cleaning spray pipes 626 and the spray ports 629 of every two adjacent third transverse spray pipes 627. The primary cleaning section 1131 of the conveyor chain 11 includes two front and rear vertical conveying parts 1135 and 1137, and also includes a transverse conveying part 1136 located between the two. The rear vertical conveying part 1135 extends vertically downward from the upper rear part of the immersion tank 61, passes behind the rear row of spray pipes 624 and extends vertically downward into the rear part of the immersion tank 61, the transverse conveying part 1136 extends horizontally forward from the rear part of the immersion tank 61 to the front part of the immersion tank 61, and the front vertical conveying part 1137 extends vertically upward from the front part of the immersion tank 61 and passes between the front and rear rows of cleaning spray pipes 623 and 624. A vertical guide bar 134 is provided in front of the front and rear vertical conveying parts 1135 and 1137. The vertical guide bar 134 can guide the cutlery cage 10 passing through the vertical conveying parts 1135 and 1137 so that the cutlery cage 10 remains in a nearly vertical state and also maintains an upright state with the cage opening 100 facing upward. The front and rear water baffles 621 and 622 can block the water splashed thereon and prevent the water from being sprayed to other places.

[0031] See Figure 3 and Figure 5The bottom and side of the tableware carrier cage 10 are provided with slag discharge ports 109, wherein the slag discharge ports 109 located at the front and rear sides also serve as cleaning liquid injection ports 1091. The tableware carrier cage 10 drives the tableware loaded thereon to move forward from the tableware receiving section 111 of the conveying chain 11 to the carrying section 112, and then continues to move forward from the carrying section 112 to the top of the vertical conveying section 1135 at the rear of the primary cleaning section 1131, which is located above the immersion tank 61. The rear vertical conveying part 1135 of the primary cleaning section 1131 conveys the tableware carrier cage 10 downward to the immersion tank 10. The tableware carrier cage 10 and the tableware on it pass behind the rear row of spray pipes 624 during transportation, that is, pass above the immersion tank 10. During this process, the six third horizontal cleaning spray pipes 627 of the rear row of horizontal cleaning spray pipes 624 spray cleaning liquid mixed with negative ion water toward the tableware carrier cage 10, and spray the cleaning liquid from the cleaning liquid spraying port 1091 of the tableware carrier cage 10 to the tableware loaded on the tableware carrier cage 10, and spray away the food residues remaining on the tableware, so that the tableware on the tableware carrier cage 10 is sprayed and cleaned in this way. 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 to the outside of the tableware carrier cage 10 and fall back into the immersion tank 61. The rear vertical conveying part 1135 of the conveying chain 11 conveys the tableware carrier cage 10 vertically downward from the upper rear part of the immersion tank 61 into the rear part of the immersion tank 61 in an upright state, and conveys the tableware loaded on the tableware carrier cage 61 from the upper rear part of the immersion tank 61 downward into the rear part of the immersion tank 61 for immersion. The immersion tank 61 automatically cleans the dead corners of the tableware that are not sprayed by immersion, so that the food residues left on the tableware leave the tableware. The tableware carrier cage 10 moves from the rear vertical conveying part 1135 of the conveying chain 11 to the horizontal conveying part 1136. The horizontal conveying part 1136 conveys the tableware carrier cage 10 horizontally from the rear part of the immersion tank 61 to the front part of the immersion tank 61 in an upright state, and conveys the tableware loaded on the tableware carrier cage 10 from the rear part of the immersion tank 61 to the front part of the immersion tank 61. The tableware carrying cage 10 moves from the horizontal conveying part 1136 of the conveying chain 11 to the front vertical conveying part 1137. The vertical conveying part 1137 sends the tableware carrying cage 10, which has been sent to the front of the immersion tank 61, away from the immersion tank 61 in an upright state vertically upward from the front of the immersion tank 61, and sends the washed tableware loaded on the tableware carrying cage 10 vertically upward from the front of the immersion tank 61 to the outside of the immersion tank 61. The tableware carrying cage 10 drives the tableware loaded thereon to pass upward between the front and rear rows of horizontal cleaning spray pipes 623 and 624 during transportation. The front and rear rows of horizontal cleaning spray pipes 623 and 624 respectively spray cleaning liquid onto the tableware loaded on the tableware carrying cage 10, spray and clean the tableware that has been sent to the upper front of the immersion tank 61, and the cleaning liquid and the food residues remaining on the tableware fall back into the immersion tank 61 together, which will not be repeated here.The tableware cleaning device generates water containing negative ions (i.e., negative ion water) through the existing negative ion water generator 95, and mixes the negative ion water and clean water into a cleaning liquid, which replaces the existing detergent to wash the tableware. The water containing negative ions can remove food residues such as grease from the tableware. Compared with detergent, water produces less foam in the process of the tableware carrying cage 10 driving the tableware to immerse into the immersion tank 61 and the tableware carrying cage 10 leaving the immersion tank 61 to fish the tableware out of the immersion tank, and the foam generated by water will burst in a short time, and the foam will not accumulate more and more in the immersion tank 61, and will not overflow outside the immersion tank 61, and will not pollute the environment. Since the spray cleaning mechanism 62 is located above the immersion tank 61 and is arranged vertically, it only needs to occupy the space above the immersion tank 61, and does not need to occupy the space on the side of the immersion tank 61.

[0032] See Figure 2 The secondary spray and immersion washing unit 620 is substantially the same as the primary spray and immersion washing unit 610, except that the primary spray and immersion washing unit 610 relies on the clean water supply pipe 91 and the negative ion water generator 95 to provide clean water and negative ion water as cleaning liquids, respectively, while the secondary spray and immersion washing unit 620 relies on the clean water supply pipe 91 to provide clean water as cleaning liquid throughout the entire process, which will not be described in detail. The primary cleaning section 1131 of the conveying chain 11 is the same as the secondary cleaning section 1132, which will not be described in detail. Under the conveyance of the conveying chain 11, multiple tableware carrying cages 10 are successively immersed in the immersion pool 61 of the primary spray and immersion washing unit 610 and successively receive spraying from the spray cleaning mechanism 62 of the primary spray and immersion washing unit 61, and then successively immersed in the immersion pool of the secondary spray and immersion washing unit 620 and successively receive spraying from the spray cleaning mechanism of the secondary spray and immersion washing unit 620.

[0033] See Figure 2 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 "U" shaped, 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 the cleaned tableware is sent 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 and remove the cleaning liquid on the tableware. A vertical guide bar is provided at the drying box 71, and the vertical guide bar can guide the tableware cage 10 entering the drying box 71 so that the tableware cage 10 remains in a nearly vertical state and the cage mouth 100 remains in an upright state facing upwards, which will not be described in detail. The tableware carrying cage 10 continues to move along the drying section 114 and leaves the drying box 71 in an upright state, and delivers the dried tableware to the outside of the drying box 71.

[0034] See Figure 2The automatic tableware washing device is provided with two discharging guide shafts 134 and 135 at the rear of the tableware outlet 102, and the front discharging guide shaft 134 is higher than the rear discharging guide shaft 135. The tableware unloading section 115 of the conveyor 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, wherein the lifting section 1151 is located behind the rear discharging guide shaft 135, the inclined section 1152 is located above the front discharging guide shaft 134, and the reset section 1153 is located in front of the front discharging guide shaft 134. Driven by the conveying chain 11, the tableware carrying cage 10 moves 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 discharge guide parts, and the tableware carrying cage 10 is first guided by the rear discharge guide shaft 135, and rotates clockwise to the upper rear side with the hanging angle 105 as the rotation center to lean against the front discharge guide shaft 134, and then guided by the front discharge guide shaft 134, it continues to rotate clockwise to the upper rear side with the hanging angle 105 as the rotation center to make the cage mouth 100 tilt downward to align with the tableware output port 102, and pour the dried tableware out from the tableware output port 102 in an inverted state. After the tableware is poured out, the tableware carrier cage 10 moves from the inclined section 1152 to the reset section 1153. During this process, the tableware carrier cage 10 is no longer guided by the two material discharging guide shafts 134 and 135, and is in a naturally 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 carrier cage 10 moves from the reset section 1153 to the rotation section 119, and is guided by the front arc-shaped guide bar 1312. It rotates counterclockwise to the front upper 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 rotation section 119 to the tableware receiving section 111 to reload the tableware. It will not be repeated here.

[0035] See Figure 3 In this embodiment, the tableware carrying cage 10 is used as the tableware carrying container, and the tableware carrying cage 10 is provided with a slag discharge port 109 at the bottom and the side. In other embodiments, a tableware box having slag discharge ports only at the front and rear sides may be used instead of the tableware carrying cage 10 as the tableware carrying container, or a tableware clamping rack having open front and rear sides may be used instead of the tableware carrying cage 10 as the tableware carrying container.

[0036] See Figure 2The conveying mechanism of this embodiment is composed of a conveying chain 11 and a chain drive assembly 12. In other embodiments, the existing conveying belt can be used to replace the conveying chain 11, and correspondingly, the existing belt drive assembly can be used to replace the chain drive assembly 12, and the conveying mechanism is composed of a conveying belt and a belt drive assembly. In other embodiments, other forms of conveying mechanisms can be used, such as using an existing manipulator to clamp the tableware carrier cage 10 and then letting the manipulator convey the tableware cage 10 to pass through the tableware delivery port 101, the cleaning module 6, the drying module 7 and the tableware output port 102 in sequence.

[0037] See Figure 2 In this embodiment, the cleaning module 6 includes a primary spray and immersion unit 610 and a secondary spray and immersion unit 620, and each of the spray and immersion units 610 and 620 is provided with a spray mechanism 62 and an immersion tank 61. The cleaning modules of other embodiments may be modified to: only one of the units is provided, and the other unit is eliminated; or the spray mechanism 62 of each unit is eliminated, and the immersion tank 61 is retained; or the immersion tank 61 is eliminated, and the spray mechanism 62 is retained, and the clean water supply pipe 91 and the negative ion water generator 95 directly provide cleaning liquid for the spray mechanism 62.

[0038] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
