Description

Technical Field

[0001] The utility model relates to the technical field of tableware spraying and soaking, in particular to a circulating tableware spraying and soaking device. Background Art

[0002] People can clean dishes by dipping them: first, pour cleaning liquid into the dipping tank, then place a batch of dishes with food residue in the dipping tank for dipping. During the dipping process, the food residue separates from the dishes and mixes into the cleaning liquid. After the dishes are removed from the dipping tank, the next batch of dishes can be placed in the dipping tank for dipping. Because food residue mixes into the cleaning liquid with each dipping and remains in the dipping tank, the cleaning liquid in the dipping tank becomes increasingly dirty, and the dipping effect becomes increasingly poor. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a circulating tableware spraying and immersion washing device, which can discharge food residues in the immersion pool and maintain a good immersion effect.

[0004] In order to solve the above-mentioned technical problems, the utility model provides a circulating tableware spray and immersion device, which includes a immersion tank for immersing tableware; a first floating object discharge outlet is opened at the top of the immersion tank to discharge floating food residues, and / or a first sediment discharge outlet is opened at the bottom of the immersion tank to discharge sediment food residues, and an openable first sediment discharge valve is provided at the first sediment discharge outlet; a spray cleaning mechanism is provided above the immersion tank, and the device is provided with a first infusion pump to pump the cleaning liquid in the immersion tank to the spray cleaning mechanism, and the spray cleaning mechanism sprays the cleaning liquid onto the tableware located above the immersion tank for spray cleaning, and the cleaning liquid sprayed on the tableware falls back into the immersion tank for recycling.

[0005] Furthermore, the invention comprises a controller electrically connected to the first sediment discharge valve.

[0006] Furthermore, a cleaning liquid supply pipe is provided for providing cleaning liquid to the immersion tank, a liquid inlet valve is provided on the cleaning liquid supply pipe, and a water level sensor is provided in the immersion tank; a controller is included, and the controller is electrically connected to the liquid inlet valve and the water level sensor.

[0007] Furthermore, a conveying mechanism is provided to convey the tableware from the back to the front to the immersion tank, and a residue removal mechanism is provided during the conveying process to remove food residues on the tableware.

[0008] Furthermore, a second infusion pump and a cleaning liquid storage tank are provided. The second infusion pump pumps the cleaning liquid in the cleaning liquid storage tank to the slag removal mechanism, and the slag removal mechanism sprays the cleaning liquid to the tableware, thereby removing food residues on the tableware.

[0009] Furthermore, the slag removal mechanism is located above the cleaning liquid storage tank, and the cleaning liquid sprayed onto the tableware by the slag removal mechanism falls back into the cleaning liquid storage tank.

[0010] Furthermore, at least one discharge port discharges into the cleaning liquid storage tank.

[0011] Furthermore, a second floating object discharge port is opened at the top of the cleaning liquid storage tank, and / or a second sediment discharge port is opened at the bottom of the cleaning liquid storage tank, and a second sediment discharge valve is provided at the second sediment discharge port.

[0012] Furthermore, a heater is provided to heat the cleaning liquid in the immersion tank.

[0014] When washing tableware, food residue on the tableware separates from the tableware and then enters the cleaning liquid. Some of the food residue floats on the surface of the cleaning liquid, while the rest sinks to the bottom of the washing tank. Because this device has a floating object discharge outlet at the top of the washing tank and / or a sediment discharge outlet at the bottom of the washing tank, when the cleaning liquid in the washing tank becomes dirty, all that is required is: allowing the tableware to enter the washing tank so that the level of the cleaning liquid in the washing tank rises above the floating object discharge outlet, and the food residue floating on the cleaning liquid surface is discharged from the floating drainage outlet; and / or opening the sediment discharge valve to allow the food residue that has sunk to the bottom of the washing tank to be discharged from the sediment discharge outlet. This device can discharge food residue from the washing tank, keeping the cleaning liquid in the washing tank clean and thus maintaining a good washing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further described in detail below in conjunction with specific embodiments.

[0027] Automatic tableware cleaning equipment Figure 1 The tableware cleaning device is provided with a tableware inlet 101 at the rear and a tableware outlet 102 at the front. People put a set of tableware with food residue to be cleaned (not shown in the figure) into the tableware cleaning device through the tableware inlet 101. The tableware cleaning device automatically removes the food residue on the tableware and automatically cleans the tableware to achieve tableware purification. The cleaned tableware is sent out from the tableware outlet 102.

[0028] Automatic tableware cleaning equipment Figure 2, including a conveyor chain 11 in the front-to-back direction and a chain drive assembly 12 that drives and connects the conveyor chain 11. A plurality of tableware carrying cages 10 arranged along the front-to-back direction of the conveyor chain 11 are installed on the conveyor chain 11. The plurality of tableware carrying cages 10 are suspended and installed on the chain links of the conveyor chain 11. The conveyor chain 11 serves as a conveyor belt and forms a conveying mechanism with the chain drive assembly 12 to transport the plurality of tableware carrying cages 10. The chain drive assembly 12 is a prior art. A slag removal module 5, a cleaning module 6, and a drying module 7 are provided in sequence from back to front between the tableware loading port 101 and the tableware output port 102. These three modules 5, 6, and 7 constitute a tableware purification module. 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 back to front: a tableware receiving section 111 passing from the tableware inlet 101, a slag removal section 112 passing from the slag removal module 5, a cleaning section 113 passing from the cleaning module 6, a drying section 114 passing from the drying module 7, and a tableware unloading section 115 passing from the tableware outlet 102. The automatic tableware purification device includes a controller electrically connected to the chain drive assembly 12, which controls the chain drive assembly 12 to drive the conveyor chain 11, thereby sequentially transporting multiple tableware carrier cages 10 to various locations along the conveyor chain 11. The tableware carrier cages 10 serve as tableware carriers, with their cage openings 100 facing upward in an upright position, for transporting tableware. The conveyor chain 11 first delivers the tableware carrying cage 10 in an upright state to the tableware delivery port 101 to load the tableware; then the tableware carrying cage 10 is conveyed from the back to the front so that the tableware carrying cage 10 remains in an upright state and passes through the slag removal module 5, the cleaning module 6 and the drying module 7 in turn. These three modules 5, 6 and 7 purify the tableware respectively. Specifically, the slag 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 conveyor chain 11 continues to convey the tableware carrying cage 10 and delivers the tableware carrying cage 10 to the tableware output port 102 to pour out the dried tableware; then the tableware carrying cage 10 that has poured out the tableware is conveyed to the tableware delivery port 101 through the rotating section 119 to be loaded with tableware again, and this cycle is repeated. Since the tableware is loaded in the tableware carrying cage 10 , the tableware carrying cage can restrict the tableware, ensuring that the tableware will not be scattered into the deslagging module 5 , the cleaning module 6 and the drying module 7 during the deslagging, cleaning and drying processes.

[0029] See Figure 2The controller controls the chain drive assembly 12 to drive the conveyor chain 11 to perform intermittent conveying as follows: the conveyor chain 11 conveys an unloaded tableware carrier cage 10 to the tableware inlet 101 and then stops for 3.5 seconds. Within 3.5 seconds, people put tableware into the tableware carrier cage 10 from the tableware inlet 101. Then, within 3.5 seconds, the conveyor chain 11 conveys the loaded tableware carrier cage 10 forward and delivers the next unloaded tableware carrier cage 10 to the tableware inlet 101. And so on. In this way, multiple tableware carrier cages 10 pass through the tableware inlet 101 and are loaded with multiple sets of tableware. After loading the tableware, the multiple tableware carrier cages 10 pass through the deslagging module 5, the cleaning module 6, and the drying module 7.

[0030] See Figure 2 A transverse support bar 131 is provided below the rotating section 119 of the conveyor chain 11. For example, an unloaded tableware carrier cage 10 located on the rotating section 119 of the conveyor chain 11 is positioned horizontally with its cage opening 100 facing backward. Its rear upper corners serve as hanging angles 105, hanging from the links of the conveyor chain 11. Its front lower corners 106 and rear lower corners 107 are supported on the transverse support bar 131, allowing it to move backward under the conveyor chain 11. A rear curved guide bar 1311 extending downward and rearward is provided at the rear end of the transverse support bar 131. The automatic tableware cleaning equipment is equipped with a vertical feed guide bar 132 behind the tableware receiving section 111 of the conveyor 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 bar 1311 and moves downward along the rear arc-shaped guide bar 1311 under the action of gravity. Guided by the rear arc-shaped guide bar 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 is raised backward to support the feeding guide bar 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. Its cage mouth 100 is tilted toward the rear and upward, and the tableware carrying cage 10 is in an upright state, ready for tableware to be loaded.

[0031] See Figure 2 , a tableware loading guide plate 133 with a lower front and a higher back is provided at the tableware loading port 101. The tableware receiving section 111 of the conveying chain 11 transports the tableware carrying cage 10 downwards. During this process, the tableware carrying cage 10 always remains in a tableware receiving state under the guidance of the feeding guide bar 132. The tableware receiving section 111 of the conveying chain 11 transports the tableware carrying cage 10 to the tableware loading port 101, so that the cage mouth 100 of the tableware carrying cage 10 is aligned with the tableware loading port 101 and the tableware loading guide plate 133, and the lower end of the cage mouth 10 is lower than the tableware loading guide plate 133. Then the conveying chain 11 pauses and allows the tableware carrying cage 10 to stay at the tableware loading port 101 for 3.5 seconds. Figure 2 Within 3.5 seconds, people put tableware into the tableware inlet 101. The tableware is guided by the tableware guide plate 133 and loaded downward from the cage opening 100 into the tableware carrier cage 10. After 3.5 seconds, the tableware receiving section 111 of the conveyor chain 11 sends the tableware carrier cage 10 loaded with tableware downward from the tableware inlet 101.

[0032] See Figure 2 、 Figure 3 and Figure 4 The conveyor chain 11 transports the tableware carrier cage 10 and the tableware thereon from the back to the front to the cleaning module 6. The slag removal module 5 is located behind the cleaning module 6, that is, the slag removal module 5 is located in the conveying path of the tableware carrier cage 10 and the tableware thereon. The slag removal module 5 includes a slag removal box 51 with an upward opening. A transverse partition 52 is provided inside the slag removal box 51. The transverse partition 52 divides the interior of the slag removal box 51 into an upper portion 511 and a lower portion 512. The transverse partition 52 has a vertically extending slag discharge opening 521 that connects the upper portion 511 of the slag removal box 51 to the lower portion 512. The lower portion 512 of the slag removal box 51 is provided with a residue conveying mechanism 53, which is aligned with the slag discharge opening 521 of the transverse partition 52. The tableware receiving section 111 of the conveyor chain 11 and the tableware carrying cage 10, which moves downward along this section, are both located above the de-slag box 51. The tableware carrying cage 10 is located above the de-slag opening 521. De-slag openings 109 are provided on the bottom and sides of the tableware carrying cage 10. As tableware is loaded downwardly into the tableware carrying cage 10, some food residue on the food residue falls forward and is discharged from the de-slag opening 109 of the tableware carrying cage 10. Most of this food residue falls through the de-slag opening 521 of the transverse partition 52 onto the de-slag conveying mechanism 53, where it is received and conveyed away. A small portion falls onto the transverse partition 52. The de-slag section 112 of the conveyor chain 11 comprises a rearward transverse de-slag section 1121 and a forward vertical de-slag section 1122. The tableware carrier cage 10 moves from the lower end of the tableware receiving section 111 of the conveyor chain 11 to the transverse debris removal section 1121. The transverse debris removal section 1121 transports the tableware carrier cage 10 forward and laterally, gradually moving the tableware carrier cage 10 away from the feed guide bar 132. During this process, the tableware carrier cage 10 as a whole rotates downward counterclockwise with the hanging angle 105 as the rotation center under the action of gravity to a naturally drooping state, pouring out most of the food residue on the tableware. This food residue is discharged from the tableware carrier cage 10 through the debris discharge port 109 to the outside of the tableware carrier cage 10. Most of the food residue falls from the debris discharge port 521 of the transverse partition 52 onto the residue conveying mechanism 53, where it is received and transported away. A small portion of the food residue falls onto the transverse partition 52. Figure 2Because the tableware carrier cage 10 is suspended from the conveyor chain 11 only by its hanging corners 105, the tableware carrier cage, in its naturally drooping state, is not vertically upward but rather slightly tilted, yet still in an upright position with its cage opening 100 facing upward. The slag removal module 5 is equipped with vertical guide bars 134 at the vertical slag removal section 1122 of the conveyor chain 11. As the tableware carrier cage 10 moves from the horizontal slag removal section 1121 to the vertical slag removal section 1122 of the conveyor chain 11, the naturally drooping tableware carrier cage 10 approaches and abuts against the vertical guide bars 134. Guided by these bars, it rotates counterclockwise to a nearly vertical position, maintaining its cage opening 100 facing upward and maintaining an upright position.

[0033] See Figure 4 The lower portion of the deslagging tank 51 is connected to a clean water supply pipe 91, which is provided with a liquid inlet valve 911. A heater 92 and a bottom water level sensor 93 are provided at the bottom of the deslagging tank 51. The heater 92 is lower than the sensing height of the bottom water level sensor 93. A cleaning liquid level sensor 94 is provided at the lower portion 512 of the deslagging tank 51. The cleaning liquid level sensor 94 is higher than the bottom water level sensor 93. A controller is electrically connected to the liquid inlet valve 911, the bottom water level sensor 93, the heater 92, and the cleaning liquid level sensor 94. The controller controls the liquid inlet valve 911 to open, allowing the clean water supply pipe 91 to input clean water into the lower portion 512 of the deslagging tank 51. The lower portion 512 of the deslagging tank 51 is used as a clean water storage tank to store clean water. Since the clean water storage tank belongs to the deslagging module 5, this article refers to the clean water storage tank as the deslagging tank 512. As clean water is input into the deslagging tank 512, the water level in the deslagging tank 512 gradually rises. Because heater 92 is lower than the sensing height of bottom water level sensor 93, when the water level in deslagging tank 512 rises to the sensing height of bottom water level sensor 93, causing bottom water level sensor 93 to generate an electrical signal, the water level in deslagging tank 512 is higher than heater 92, and the controller controls heater 92 to start heating the clean water in deslagging tank 512. When the clean water level rises to the sensing height of cleaning liquid level sensor 94, causing cleaning liquid level sensor 94 to generate an electrical signal, the controller controls liquid inlet valve 911 to close.

[0034] See Figure 3 、 Figure 4 and Figure 6The slag removal module 5 is also a tableware slag removal spray device, which is provided with a spray slag removal mechanism 54 above the front of the slag removal box 51. The spray slag removal mechanism 54 includes two front and rear water baffles 541 and 542. Two front and rear slag removal spray pipes 543 and 544 are provided between the front and rear water baffles 541. The front slag removal spray pipe 543 includes 9 spray ports 546 arranged vertically and a horizontal slag removal spray pipe 545 facing backward. The rear slag removal spray pipe 544 includes 3 spray ports arranged vertically (not shown in the figure due to the viewing angle) and a horizontal slag removal spray pipe 545 facing forward. The spray ports 546 of each adjacent two horizontal slag removal spray pipes 545 are staggered horizontally, as shown in FIG. Figure 7 The deslagging module 5 is equipped with a deslagging liquid infusion pump 55. The inlet end of the deslagging liquid infusion pump 55 is connected to the deslagging tank 512, and the outlet end is connected to 12 horizontal deslagging spray pipes 545. The pump pumps clean water from the deslagging tank 512 into the horizontal deslagging spray pipes 545, providing clean water for the horizontal deslagging spray pipes 545. The vertical deslagging section 1122 of the conveyor chain 11 passes between the front and rear rows of horizontal deslagging spray pipes 543 and 544. The tableware carrier cage 10 remains upright and moves upward along the vertical deslagging section 1122, passing between the front and rear rows of transverse deslagging spray pipes 543 and 544. During this process, the deslagging openings 109 on the front and rear sides of the tableware carrier cage 10 also serve as cleaning liquid injection ports 1091. The front and rear rows of transverse deslagging spray pipes 543 and 544 spray clean water laterally into the tableware carrier cage 10 from the cleaning liquid injection ports 1091, spraying it onto the tableware loaded on the tableware carrier cage 10. Using clean water as the cleaning liquid, most of the remaining food residue is sprayed off the tableware, thereby removing food residue from the tableware and achieving purification of the tableware. The front and rear water retaining plates 541 and 542 can block water splashing onto them, preventing the water from being sprayed elsewhere. The deslagging module 5 removes food residue from the tableware by spraying, using the impact of the cleaning liquid sprayed onto the tableware to flush away food residue. Compared to immersion deslagging, spraying deslagging can more effectively remove food residue with higher viscosity from the tableware. The vertical deslagging section 1122 and the tableware carrier cage 10 that moves upward along the vertical deslagging section 1122 are located above the front of the deslagging box 51 and also above the front of the residue conveying mechanism 53. The water sprayed onto the tableware, along with the food residue, is discharged from the deslagging outlet 109 of the tableware carrier cage 10 to the outside of the tableware carrier cage 10, first falling onto the transverse partition 52 and then flowing along the transverse partition 52 to the deslagging outlet 521, incidentally flushing away food residue that had previously fallen onto the transverse partition 52. The water and food residues fall from the residue 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 and then sends them away. The water passes through the residue conveying mechanism 53 and falls back into the residue removal pool 512 (see FIG. Figure 4 ) for reuse.

[0035] See Figure 3 、 Figure 4 and Figure 5 The residue conveying mechanism 53 comprises a residue conveyor belt 531 and a conveyor belt drive mechanism 532 that drives and connects to the residue conveyor belt 531. The conveyor belt drive mechanism 532 is conventional technology. The left end 5311 of the residue conveyor belt 531 is terminated by a lateral extension 533 that extends laterally to the side of the residue removal tank 512. The residue conveyor belt 531 is provided with filter holes 5312. When water and food residue fall onto the residue conveyor belt 531, the water and some food residue smaller than the filter holes 5312 flow downward through the filter holes 5312 and fall into the residue removal tank 512. Food residue larger than the filter holes 5312 cannot flow downward through the filter holes 5312 and remains on the residue conveyor belt 531. The conveyor belt drive mechanism 532 drives the residue conveyor belt 531 to transport the food residue to the left end 5311 of the residue conveyor belt 531, where it is then dumped to the side of the residue removal tank 512.

[0036] See Figure 4 The cleaning module 6 also serves as a tableware spray and immersion device, comprising a primary spray and immersion unit 610 and a secondary spray and immersion unit 620. The cleaning section 113 of the conveyor 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 spray and immersion unit 610, while the secondary cleaning section 1132 passes through the secondary spray and immersion unit 620. The tableware carrier 10 first moves forward from the deslagging section 112 of the conveyor chain 11 to the primary cleaning section 1131, i.e., from the deslagging module 5 to the cleaning module 6, where it is sprayed and immersed in the primary spray and immersion unit 610. It then moves forward from the primary cleaning section 1131 to the secondary cleaning section 1132, where it is sprayed and immersed in the secondary spray and immersion unit 620.

[0037] First level spray leaching unit 610 Figure 8 , including a leaching pool 61, the leaching pool 61 and Figure 4The two slag removal pools 512 are roughly the same. Specifically, both are connected to a clean water supply pipe 91, and both are provided with a liquid inlet valve 911 on the clean water supply pipe 91. Both are equipped with a heater 92, a bottom water level sensor 93 and a cleaning liquid level sensor 94 in the pool. The heater 92 is lower than the sensing height of the bottom water level sensor 93, and the cleaning liquid level sensor 94 is higher than the bottom water level sensor 93. The controller electrically connects the liquid inlet valve 911, the heater 92, the bottom water level sensor 93 and the cleaning liquid level sensor 94; the controller controls the liquid inlet valve 911 to open so that the clean water supply pipe 91 inputs clean water into the pool, and when the water level in the pool rises to the sensing height of the bottom water level sensor 93, controls the heater 92 to heat the cleaning liquid in the pool, and controls the liquid inlet valve 911 to close when the water level in the pool rises to the sensing height of the cleaning liquid level sensor 94. The difference between the leaching tank 61 and the slag removal tank 512 is that the slag removal tank 512 relies on the clean water supply pipe 91 to provide clean water as a cleaning liquid throughout the process; in addition to relying on the clean water supply pipe 91 to provide clean water, the leaching tank 61 is also connected to an existing negative ion water generator 95. This embodiment uses the negative ion water generator 95 provided by Kunshan Nano Green Energy Environmental Protection Technology Co., Ltd. The negative ion water generator 95 generates water containing hydroxide negative ions (i.e., negative ion water) by electrolyzing water. The leaching tank 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 feeds 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 ion water level sensor 96, the ion water level sensor 96 generates an electrical signal. The controller then controls the negative ion water generator 95 to stop operation and then controls the liquid inlet valve 911 to open, allowing the clean water supply pipe 91 to feed clean water into the immersion tank 61. The clean water and negative ion water mix in the immersion tank 61 to form a cleaning solution.

[0038] First level spray leaching unit 610 Figure 9 、 Figure 10 and Figure 11A 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. Two rows of cleaning spray pipes 623 and 624 are respectively provided 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 nine spray ports 629 arranged vertically and facing rearward. The rear row of cleaning spray pipes 624 includes a second horizontal cleaning spray pipe 626 with three spray ports 629 arranged vertically and facing forward, and a third horizontal cleaning spray pipe 627 with six spray ports 629 facing rearward. The water baffle 622 at the rear is provided with a liquid spray port 6221, and the spray port 629 of the second horizontal cleaning spray pipe 626 is aligned with the liquid spray port 6221 in front, so the water baffle 622 at the rear will not block the spray port 629 of the second horizontal cleaning spray pipe 626. The first-level spray immersion unit 610 also includes a cleaning infusion pump 63, the liquid inlet end of the cleaning 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, and 627, and the cleaning liquid in the immersion tank 61 is pumped to the 18 horizontal cleaning spray pipes 625, 626, and 627 to provide cleaning liquid for these 18 horizontal cleaning spray pipes 625, 626, and 627. The spray ports 629 of each two adjacent first horizontal cleaning spray pipes 625 are staggered laterally with each other (see Figure 7 ), the same applies to the spray ports 629 of every two adjacent second horizontal cleaning spray pipes 626 and the spray ports 629 of every two adjacent third horizontal spray pipes 627. The first-level cleaning section 1131 of the conveyor chain 11 includes two front and rear vertical conveying parts 1135 and 1137, and also includes a horizontal 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 horizontal conveying part 1136 extends horizontally from the rear part of the immersion tank 61 to the front part of the immersion tank 61. 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 the cage opening 100 remains upright and facing upward. No further details are given.

[0039] See Figure 2 and Figure 9The tableware carrier cage 10 drives the tableware loaded thereon to move forward from the debris removal section 112 of the conveyor chain 11 to the top of the rear vertical conveying portion 1135 of the primary cleaning section 1131, located above the immersion tank 61. The rear vertical conveying portion 1135 of the primary cleaning section 1131 transports the tableware carrier cage 10 downward so that the tableware carrier cage 10 and the tableware loaded thereon pass behind the rear row of spray pipes 624. 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. The cleaning liquid is sprayed from the cleaning liquid injection port 1091 of the tableware carrier cage 10 onto the tableware loaded on the tableware carrier cage 10, spraying away any remaining food residue on the tableware. In this manner, the tableware on the tableware carrier cage 10 is spray-cleaned, thereby purifying the tableware. The slag outlet 109 of the tableware carrier cage 10 also serves as a liquid outlet. Cleaning liquid and food residue are discharged from the slag outlet 109 to the outside of the tableware carrier cage 10 and fall back into the immersion tank 61, allowing the cleaning liquid to be recycled. The rear vertical conveying portion 1135 of the conveyor chain 11 transports the tableware carrier cage 10 vertically downward from the upper rear portion of the immersion tank 61 in an upright position into the rear portion of the immersion tank 61. The tableware loaded on the tableware carrier cage 61 is transported downward from the upper rear portion of the immersion tank 61 into the rear portion of the immersion tank 61 for immersion. The immersion tank 61 automatically cleans the unsprayed corners of the tableware through immersion, removing any remaining food residue from the tableware and purifying the tableware. The tableware carrying cage 10 moves from the vertical conveying part 1135 at the rear of the conveying chain 11 to the transverse conveying part 1136. The transverse conveying part 1136 conveys the tableware carrying cage 10 in an upright state from the rear of the immersion tank 61 to the front of the immersion tank 61, and conveys the tableware loaded on the tableware carrying cage 10 from the rear of the immersion tank 61 to the front 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 that 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. During this process, the tableware carrying cage 10 drives the tableware loaded on it upward to pass 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 cleaning liquid onto the tableware loaded on the tableware carrying cage 10, spraying and cleaning the tableware that has been sent to the top of the front of the immersion tank 61 to purify the tableware. The cleaning liquid and the food residue remaining on the tableware fall back into the immersion tank 61 together, which will not be repeated here.This tableware cleaning device uses an existing negative ion water generator 95 to generate water containing negative ions (i.e., negative ion water), and mixes the negative ion water with clean water to form a cleaning liquid, which replaces the existing detergent to soak the tableware. The water containing negative ions can remove food residues such as oil stains from the tableware. Compared with detergent, water produces less foam when the tableware carrying cage 10 drives the tableware to immerse in the immersion tank 61 and when the tableware carrying cage 10 leaves the immersion tank 61 to fish the tableware out of the immersion tank. In addition, the foam generated by water will burst in a short time, and the foam will not accumulate in the immersion tank 61, nor will it 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.

[0040] See Figure 11Food residue entering the immersion tank 61 will partially float on the surface of the cleaning liquid, while the remaining portion will sink to the bottom of the immersion tank 61. Similarly, food residue entering the deslagging tank 512 will partially float while the remaining portion will sink to the bottom. Both the immersion tank 61 and the deslagging tank 512 have floating debris discharge ports 97 at their tops. Both the immersion tank 61 and the deslagging tank 512 have floating debris discharge ports 97 above the sensing height of the cleaning liquid level sensor 94. Initially, the cleaning liquid in the tanks will not be discharged from the floating debris discharge ports 97. The floating debris discharge port 97 of the immersion tank 61 is connected to an immersion floating debris discharge pipe 98, which leads to the deslagging tank 512. In other words, the floating debris discharge port 97 of the immersion tank 61 discharges into the deslagging tank 512. The floating debris discharge port 97 of the deslagging tank 512 is connected to a deslagging floating debris discharge pipe 99, which leads to the outside world. When the tableware carrying cage 10 is immersed in the immersion tank 61, the liquid level of the immersion tank 61 will rise to above the float discharge port 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 from the immersion tank 61 together with a portion of the cleaning liquid from the float discharge port 97 at the top of the immersion tank 61 to the outside of the immersion tank 61, and enter the slag removal tank 512 through the immersion float discharge pipe 98, causing the liquid level of the slag removal tank 512 to rise to above the float discharge port 97 of the immersion tank 512. The food residues floating on the liquid surface of the cleaning liquid in the immersion tank 512 will enter the slag removal float discharge pipe 99 from the float discharge port 97 at the top of the slag removal tank 512, and be discharged to the outside of the slag removal tank 512 through the slag removal float discharge pipe 99. Because there is less food residue in the immersion tank 61 than in the deslagging tank 512, the cleaning liquid in the immersion tank 61 is cleaner than that in the deslagging tank 512. This cleaning liquid is then discharged from the immersion floating debris discharge pipe 98 to the deslagging tank 512 and can be reused by the deslagging module 5. Every five minutes, the controller controls the two liquid inlet valves 911 to open for 30 seconds, allowing the clean water supply pipe 91 to replenish clean water to the immersion tank 61 and the deslagging tank 512. It then controls the negative ion water generator 95 to operate for one minute, allowing it to replenish negative ion water to the immersion tank 61. Both the immersion tank 61 and the deslagging tank 512 have sediment discharge outlets at their bottoms (not shown due to viewing angles) and are connected to sediment discharge pipes 90 at these outlets. Sediment discharge pipes 90 are equipped with openable sediment discharge valves 901. The controller is electrically connected to two sediment discharge valves 901 and controls them to open for 10 seconds every 10 minutes, allowing food residue at the bottom of the immersion tank 61 and the bottom of the deslagging tank 512 to be discharged from the two sediment discharge outlets into two sediment discharge pipes 90, and then discharged to the outside through the two sediment discharge pipes 90. The automatic tableware cleaning device can regularly discharge food residue from the immersion tank 61 and the deslagging tank 512, keeping the cleaning liquid in the immersion tank 61 and the deslagging tank 512 clean, thereby maintaining good immersion and deslagging effects.

[0041] See Figure 2 The secondary spray immersion unit 620 is substantially the same as the primary spray immersion unit 610, with the difference being that the primary spray immersion 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, respectively, as cleaning liquids, while the secondary spray immersion unit 620 is the same as the slag removal tank 512, and both rely 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 conveyor chain 11 is the same as the secondary cleaning section 1132, which will not be described in detail. Multiple tableware carrying cages 10, under the conveyance of the conveyor chain 11, are successively immersed in the immersion pool 61 of the primary spray immersion unit 610 and are successively sprayed by the spray cleaning mechanism 62 of the primary spray immersion unit 61, and then are successively immersed in the immersion pool of the secondary spray immersion unit 620 and are successively sprayed by the spray cleaning mechanism 62 of the secondary spray immersion unit 620.

[0042] 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 conveyor chain 11 is U-shaped, with its bottom extending into the drying box 71. The tableware carrier 10 moves from the washing section 113 of the conveyor chain 11 to the drying section 114, that is, from the washing module 6 to the drying module 7, where it delivers the washed tableware into the drying module 7. The tableware carrier 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, drying the washed tableware loaded on the tableware carrier 10 and removing the cleaning liquid from the tableware, thereby purifying the tableware. Vertical guide bars are provided in the drying box 71 to guide the tableware carrier 10 as it enters the drying box 71, maintaining a nearly vertical position and an upright position with the cage opening 100 facing upward. These details are not detailed here. 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 out of the drying box 71.

[0043] See Figure 2The automatic tableware cleaning device is equipped with front and rear discharge guide shafts 134 and 135 behind the tableware outlet 102. The front discharge guide shaft 134 is higher than the rear discharge guide shaft 135. The tableware unloading section 115 of the conveyor chain 11 is divided into a vertical lifting section 1151, a tilted section 1152 with a lower front and a higher rear, and a vertical return section 1153. The lifting section 1151 is located behind the rear discharge guide shaft 135, the tilted section 1152 is located above the front discharge guide shaft 134, and the return section 1153 is located in front of the front discharge 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 from 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 from the upper rear side with the hanging angle 105 as the rotation center to tilt the cage mouth 100 downward to align with the tableware output port 102, and the dried tableware is poured out from the tableware output port 102 in an inverted state. After dishing out the tableware, 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 discharge guide shafts 134 and 135 and is in a naturally drooping state. A front curved guide bar 1312 extends downward and forward from the front end of the transverse support bar 131. The tableware carrier cage 10 moves from the reset section 1153 to the rotation section 119. Guided by the front curved guide bar 1312, it rotates counterclockwise toward the upper front side, with the hanging angle 105 as its center of rotation, to a horizontal position with the cage opening 100 facing rearward. Its front lower corners 106 and rear lower corners 107 are supported on the transverse support bar 131, respectively. The cage then moves from the rotation section 119 to the tableware receiving section 111 to be reloaded with tableware. This will not be described in detail here.

[0044] See Figure 6 In this embodiment, a cutlery carrying cage 10 is used as a cutlery carrying container, and a slag discharge port 109 is opened on the bottom and side of the cutlery carrying cage 10. In other embodiments, a cutlery box having slag discharge ports only on the front and rear sides can be used instead of the cutlery carrying cage 10 as the cutlery carrying container, or a cutlery clamping rack with open front and rear sides can be used instead of the cutlery carrying cage 10 as the cutlery carrying container.

[0045] See Figure 2The conveying mechanism of this embodiment consists of a conveyor chain 11 and a chain drive assembly 12. In other embodiments, the conveyor chain 11 may be replaced with an existing conveyor belt, and correspondingly, the chain drive assembly 12 may be replaced with an existing belt drive assembly. The conveying mechanism consists of a conveyor belt and a belt drive assembly. Other embodiments may use other conveying mechanisms, such as using an existing robot to clamp the tableware carrier cage 10 and then have the robot transport the tableware cage 10 sequentially through the tableware loading port 101, the slag removal module 5, the cleaning module 6, the drying module 7, and the tableware outlet 102.

[0046] See Figure 3 In this embodiment, the slag removal module 5 is provided with a residue conveying mechanism 53 and a spraying slag removal mechanism 54. In other embodiments, the slag removal module may eliminate one of the mechanisms and retain the other, for example, eliminating the residue conveying mechanism 53 and retaining the spraying slag removal mechanism 54; or eliminating the spraying slag removal mechanism 53 and retaining the residue conveying mechanism 54.

[0047] See Figure 2 and Figure 9 In this embodiment, the cleaning module 6 includes a primary spray and immersion unit 610 and a secondary spray and immersion unit 620. Each spray and immersion unit 610 and 620 is equipped with a spray mechanism 62 and an immersion tank 61. Other embodiments of the cleaning module may be modified to include only one of these units and eliminate the other; or eliminate the spray mechanism 62 in each unit and retain the immersion tank 61; or eliminate the immersion tank 61 and retain the spray mechanism 62, with the clean water supply pipe 91 and negative ion water generator 95 directly supplying cleaning fluid to the spray mechanism 62.

[0048] See Figure 11 In this embodiment, the floating matter discharge outlet 97 of the leaching tank 61 is discharged to the slag removal tank 512 through the leaching floating matter discharge pipe 98. In other embodiments, the floating matter discharge outlet 97 and the sediment discharge outlet of the leaching tank 61 can be changed to discharge to the slag removal tank 512 through pipes.
