In the description of the embodiments of the present utility model, unless otherwise specified, the meaning of "multiple" is two or more.

[0037] It should also be noted that, unless otherwise clearly specified and limited, in the embodiments of the present utility model, the terms such as "setting" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two components; it can be a wireless communication connection or a wired communication connection. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. The embodiments of the present utility model are described in detail below.

[0038] The utility model provides a multi-channel commercial dishwasher detergent and drying agent distribution control system, such as Figure 1 and Figure 2As shown, it includes a tableware recognition module 1, multiple detergent channels 21, multiple drying agent channels 22, a first solenoid valve 31, a second solenoid valve 32 and a control module 4; the tableware recognition module 1 is arranged in the cleaning chamber of the commercial dishwasher, and is used to identify the number and degree of stains of the tableware to be cleaned and generate an identification signal; one end of each detergent channel 21 is connected to the detergent container, and the other end is connected to the cleaning chamber; one end of each drying agent channel 22 is connected to the drying agent container, and the other end is connected to the cleaning chamber; the first solenoid valve 31 is arranged in each detergent channel 21; the second solenoid valve 32 is arranged in each drying agent channel 22; the control module 4 is respectively connected to the tableware recognition module 1, the first solenoid valve 31 and the second solenoid valve 32; the control module 4 is used to control the opening and closing of each first solenoid valve 31 and each second solenoid valve 32 according to the identification signal.

[0039] This embodiment adopts the above-mentioned design scheme, which can realize the precise distribution control of detergent and drying agent. The tableware identification module 1 can accurately identify the number and degree of stains of tableware in the cleaning chamber, and provide key data for the subsequent distribution of detergent and drying agent. Based on these data, the control module 4 can determine the required ratio of detergent and drying agent, and then control the opening or closing of each first solenoid valve 31 and the second solenoid valve 32, and then control the number of detergent channels 21 and drying agent channels 22 opened, so as to realize the on-demand distribution of detergent and drying agent, so that the distribution of detergent and drying agent is accurately matched with the actual cleaning needs of tableware. This on-demand distribution mechanism not only ensures the optimization of chemical use during the cleaning process, but also effectively avoids waste of resources and reduces operating costs.

[0040] The system of this embodiment uses this precise and effective allocation control to enable commercial dishwashers to adapt to a variety of cleaning scenarios. Whether it is ordinary tableware with light stains or special tableware with heavy oil stains, it can provide customized cleaning solutions, thereby significantly improving the cleaning effect.

[0041] Among them, detergents and drying agents are two key chemical agents used in commercial dishwashers, which work together to ensure efficient cleaning and perfect drying of dishes. Detergents contain ingredients such as surfactants, alkaline additives and enzymes, which can effectively break down grease, remove food residues, and provide disinfection during the cleaning process to ensure the cleanliness and hygiene of dishes. Driers contain special additives such as surfactants and organic acids, which can reduce the surface tension of water, promote the rapid evaporation of water molecules on the surface of dishes, prevent the formation of water spots and stains, and reduce static electricity to avoid the re-adsorption of dust and dirt.

[0042] In the distribution control system of this embodiment, the detergent and the drying agent are each precisely controlled through multiple independent channels and solenoid valves, and the proportion and dosage of the detergent and the drying agent are intelligently adjusted according to the degree of stain and quantity of the tableware, so as to maximize the utilization of resources and optimize the quality of tableware washing. Under normal circumstances, the more the number of tableware and the higher the degree of stain, the more dosage of detergent and the drying agent is required.

[0043] For example, suppose a restaurant's dishwasher is processing a batch of tableware after dinner. The tableware recognition module 1 detects that there are moderate oil stains and food residues on the tableware, a total of 30 pieces of tableware. Based on this information, the control module 4 queries the built-in cleaning parameter table and determines that for 30 pieces of moderately stained tableware, 0.3L of detergent and 0.2L of drying agent are required. Each detergent channel 21 can provide 0.1L of detergent, and each drying agent channel 22 can provide 0.1L of drying agent, so it is determined that three detergent channels 21 and two drying agent channels 22 need to be opened. The control module 4 then sends a control instruction to the first solenoid valve 31 and the second solenoid valve 32 to open the three first solenoid valves 31 and the two second solenoid valves 32, and the remaining first solenoid valves 31 and the second solenoid valves 32 are closed.

[0044] It should be noted that the tableware quantity and stain degree recognition algorithm adopted by the tableware recognition module 1 in the present invention is a prior art in the art and has been widely used in dishwashers of many brands in the current market.

[0045] The present invention does not make any improvements to the recognition algorithms involved in the tableware recognition module 1, but directly utilizes the existing recognition algorithms. Therefore, this embodiment does not explain these algorithms in detail, nor will it cause obstacles for those skilled in the art to understand and implement the technical solutions of the present invention.

[0046] It should be understood that the innovation of the present invention does not lie in algorithm improvement, and the present invention does not claim to protect the algorithm in the tableware recognition module 1 .

[0047] In some embodiments, the multi-channel commercial dishwasher detergent and drying agent dispensing control system further includes a weight sensor 5 for detecting the weight of dishes to be washed. The weight sensor 5 is disposed at the bottom of the washing chamber and is connected to the control module 4 .

[0048] In this embodiment, the weight sensor 5 provides a multi-channel commercial dishwasher detergent and drying agent distribution control system with real-time monitoring capability of tableware weight. This improvement enables the system to dynamically adjust the amount of detergent and drying agent according to the actual weight of the tableware, ensuring that tableware of different weights can be fully and appropriately cleaned. The data of the weight sensor 5 is combined with the stain recognition of the tableware recognition module 1 to provide a more comprehensive decision-making basis for the control module 4, thereby achieving a more accurate chemical distribution strategy. This intelligent adjustment not only improves the cleaning efficiency, but also helps to reduce the waste of chemicals and reduce operating costs, while ensuring that the cleaning quality of the tableware meets high standards.

[0049] This embodiment takes into account that in most cases, the heavier the tableware, the larger the volume, and thus the larger the dosage of detergent and drying agent required. Considering only the number of tableware, there may be room for improvement in the accuracy of distribution control. Therefore, the weight of the tableware is collected by the weight sensor 5, and the control module 4 determines an initial distribution ratio and amount of detergent and drying agent according to the weight of the tableware; at the same time, the control module 4 determines another distribution ratio and amount of detergent and drying agent through the number of tableware and the degree of stains identified by the tableware identification module 1, and then takes the average of the two to obtain the final distribution ratio and amount. This can further improve the accuracy of distribution control.

[0050] In some embodiments, Figure 3 As shown, the multi-channel commercial dishwasher detergent and drying agent distribution control system also includes a first liquid level sensor 61 . The first liquid level sensor 61 is arranged in the detergent container and connected to the control module 4 .

[0051] This gives commercial dishwashers an intelligent liquid level monitoring and resource allocation capability. When the first liquid level sensor 61 detects that the liquid level of a detergent container drops to a preset low liquid level value, the control module 4 obtains this information and, in the next dishwasher cleaning task, preferentially opens the first solenoid valve 31 on the detergent channel 21 corresponding to other detergent containers with higher liquid levels, extracts detergent from other detergent containers with higher liquid levels, and maintains the remaining dosage of all detergent containers in a relatively balanced state. Avoid interruptions in cleaning due to too low dosage in a detergent container. Moreover, by balancing the usage rate of each container, the overall service life of the detergent is extended, the efficiency of detergent use is optimized, the operator's management burden on the frequency of detergent replenishment is reduced, and the operating efficiency and reliability of the entire dishwashing system are improved.

[0052] For example, a commercial dishwasher of a large catering service organization is equipped with multiple detergent containers to cope with the cleaning needs during peak hours. After a busy lunch service, the dishwasher begins to process a large number of dishes to be washed. At this time, the first liquid level sensor 61 detects that the liquid level of the detergent container numbered 1 is lower than the set low liquid level preset value. In the next cleaning cycle, the control module 4 extracts the required amount of detergent from the detergent container numbered 2 with a higher liquid level. In this way, it not only ensures that the dishwasher can continue to complete the cleaning task efficiently, but also keeps the remaining amount of all detergent containers basically consistent by extracting detergent from the container with a higher liquid level, avoiding the situation where some containers are exhausted prematurely while other containers still have a large amount of remaining. This intelligent allocation not only improves the efficiency of detergent use, but also reduces the need for emergency replenishment due to insufficient detergent, ensuring the stable operation of the dishwasher throughout the peak period.

[0053] In some embodiments, the multi-channel commercial dishwasher detergent and drying agent distribution control system further includes a second liquid level sensor 62 , which is disposed in the drying agent container and connected to the control module 4 .

[0054] Specifically, when the second liquid level sensor 62 detects that the liquid level of a drying agent container drops to a preset low liquid level threshold, the control module 4 obtains this information and, in the next dishwasher cleaning task, preferentially opens the second solenoid valve 32 on the drying agent channel 22 corresponding to other drying agent containers with higher liquid levels, extracting drying agent from other drying agent containers with higher liquid levels, so as to maintain the remaining dosage of all drying agent containers in a relatively balanced state. Avoid interruption of cleaning due to too low dosage of a drying agent container. Moreover, by balancing the consumption rate of each container, the overall use efficiency of the drying agent is improved, resource waste is reduced, and the pressure on the operator to monitor the frequency of drying agent replenishment is reduced, thereby enhancing the dishwasher's adaptive ability and continuity of operation.

[0055] For example, taking the kitchen of a large hotel as an example, the hotel's commercial dishwasher is equipped with multiple drying agent containers to meet the cleaning needs of different time periods. After a large banquet, the dishwasher began to process the piles of tableware. At this time, the second liquid level sensor 62 detects that the liquid level of the drying agent container numbered A is lower than the set low liquid level preset value. In the next cleaning cycle, the control module 4 extracts the required drying agent dosage from the drying agent container numbered B with a higher liquid level. In this way, it not only ensures that the dishwasher can continuously and efficiently complete the cleaning and drying tasks of the tableware, but also by extracting the drying agent from the container with a higher liquid level, the remaining amount of all drying agent containers is kept basically the same, avoiding the situation where some containers are exhausted prematurely while other containers still have a large amount of remaining. This intelligent allocation not only improves the efficiency of the use of the drying agent, but also reduces the emergency replenishment demand caused by insufficient drying agent, ensures the stable operation of the dishwasher during the entire cleaning process, and improves the cleaning efficiency and service quality of the hotel kitchen.

[0056] In some embodiments, the multi-channel commercial dishwasher detergent and drying agent distribution control system further includes an alarm module 7, which is connected to the control module 4 and is used to indicate that the amount of liquid in the detergent container or the drying agent container is lower than the alarm limit.

[0057] This embodiment greatly improves the user interaction and safety performance of the system through the alarm module 7. When the liquid level of the detergent or the drying agent is lower than the preset alarm limit, the alarm module 7 will issue a visual and / or auditory prompt to ensure that the operator can promptly notice the insufficient stock of the detergent or the drying agent. This timely feedback mechanism not only prevents the dishwasher from affecting the cleaning effect due to lack of detergent or the drying agent, but also avoids idling or potential damage to the equipment due to the depletion of detergent or the drying agent. The integration of the alarm module 7 improves the intelligence level of the system, makes the operation easier, and also reduces operational interruptions and additional costs caused by negligence.

[0058] For example, in the kitchen of a fast food chain, commercial dishwashers need to wash a large number of dishes quickly and efficiently. Through the alarm module 7, when the stock of detergent or rinse agent drops to the set minimum limit, the system will sound an alarm to remind the staff to replenish detergent or rinse agent immediately. In this way, even during peak hours, the dishwasher can maintain uninterrupted operation to ensure that the supply of tableware meets customer needs.

[0059] In some embodiments, the multi-channel commercial dishwasher detergent and drying agent distribution control system further includes a first flow sensor 81 , which is disposed on each detergent channel 21 and connected to the control module 4 .

[0060] This embodiment provides a real-time detergent flow monitoring capability for a commercial dishwasher through the first flow sensor 81. When the first flow sensor 81 detects that the detergent flow is lower than the normal working threshold set by the system, it can immediately feedback the flow abnormality signal to the control module 4. After receiving this signal, the control module 4 will activate the alarm module 7 and send out a clear alarm signal, such as displaying a warning message on the operation interface or issuing a sound alarm, clearly prompting the staff to immediately check whether the detergent channel 21 is blocked or whether the first solenoid valve 31 is faulty. This timely alarm mechanism not only ensures that the dishwasher can quickly get the attention and processing of maintenance personnel when the detergent flow is insufficient, avoiding the reduction of cleaning effect or extension of cleaning cycle due to insufficient flow, but also improves the reliability and maintenance efficiency of the entire dishwashing system, and ensures the continuity and consistency of tableware cleaning work.

[0061] In some embodiments, the multi-channel commercial dishwasher detergent and drying agent distribution control system further includes a second flow sensor 82 , which is disposed on each drying agent channel 22 and connected to the control module 4 .

[0062] This embodiment provides a commercial dishwasher with a real-time monitoring capability of the drying agent flow rate through the second flow sensor 82. When the second flow sensor 82 detects that the drying agent flow rate is lower than the normal operating threshold set by the system, it can immediately feedback the flow abnormality signal to the control module 4. After receiving this signal, the control module 4 will activate the alarm module 7 and send out a clear alarm signal, such as displaying a warning message on the operation interface or issuing a sound alarm, clearly prompting the staff to immediately check whether the drying agent channel 22 is blocked or whether the second solenoid valve 32 is faulty. This timely alarm mechanism not only ensures that the dishwasher can quickly get the attention and processing of maintenance personnel when the drying agent flow rate is insufficient, avoiding the reduction of the cleaning effect or the extension of the cleaning cycle due to insufficient flow, but also improves the reliability and maintenance efficiency of the entire dishwashing system, and ensures the continuity and consistency of the tableware cleaning work.

[0063] In some embodiments, the multi-channel commercial dishwasher detergent and drying agent distribution control system further includes a first distribution pump 91 , which is connected to the detergent channel 21 and to the control module 4 .

[0064] This embodiment improves the accuracy and controllability of detergent distribution through the first distribution pump 91. The first distribution pump 91 can adjust the flow rate and pressure of the detergent according to the instructions of the control module 4 to ensure that the detergent can be sprayed into the cleaning chamber evenly and in an appropriate amount to contact the tableware to be cleaned. This precise control can not only dynamically adjust the amount of detergent according to the degree and quantity of stains on the tableware to avoid waste, but also improve the cleaning efficiency and effect to ensure that the cleanliness of the tableware meets high standards. In addition, the use of the first distribution pump 91 also enhances the adaptability of the system, and can maintain a stable supply of detergent even when the viscosity of the detergent changes or the temperature fluctuates, reducing the cleaning quality problems caused by unstable pressure or uneven flow. Through this intelligent distribution pump control, the operation of commercial dishwashers is more efficient and energy-saving, while providing users with a more reliable and convenient operating experience.

[0065] In some embodiments, the multi-channel commercial dishwasher detergent and drying agent distribution control system further includes a second distribution pump 92 , which is connected to the drying agent channel 22 and to the control module 4 .

[0066] This embodiment uses the second distribution pump 92 to allow the system to accurately control the flow and pressure of the drying agent according to the actual cleaning needs and the characteristics of the tableware, ensuring that the drying agent can evenly and fully cover the surface of the cleaned tableware, accelerate the drying process and effectively prevent the formation of water spots and water stains. Through the adjustment of the second distribution pump 92, the system can adapt to different cleaning procedures and tableware materials, optimize the drying effect, reduce energy consumption, and increase the turnover rate of tableware. In addition, the intelligently controlled drying agent distribution also helps to reduce the waste of drying agents and reduce operating costs, while improving the intelligence level and ease of operation of the dishwasher, ensuring the efficiency of the cleaning process and the excellent drying quality of the tableware.

[0067] In some embodiments, the control module 4 is also connected to the spray system of the commercial dishwasher.

[0068] This embodiment provides the system with the ability to precisely control the water pressure and water flow pattern during the cleaning process. This technical improvement enables the system to dynamically adjust the working state of the spray system according to the type of tableware, the degree of stains, and the amount of chemicals added, achieving more efficient and uniform cleaning. By precisely controlling the spray system, the system not only improves the cleaning efficiency, but also helps to reduce the use of water and chemicals and reduce the impact on the environment. In addition, the precise control of the spray system also helps to improve the cleaning quality of the tableware, ensuring that every corner of the tableware can be thoroughly cleaned.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
