[0024] Example 1 like Figures 1 to 4As shown, an embodiment of the present invention provides a cleaning system comprising: a dishwasher cleaning system, a range hood cleaning system, and a water distribution control valve 2; the dishwasher cleaning system includes a dishwasher cleaning water pipe 3 for supplying cleaning water to the dishwasher; the range hood cleaning system includes a range hood cleaning water pipe 4 for supplying cleaning water to the range hood; the water distribution control valve 2 is connected to both the dishwasher cleaning water pipe 3 and the range hood cleaning water pipe 4, and is used to switch the water flow direction to control the water supply to either the dishwasher cleaning system or the range hood cleaning system; wherein... Once the dishwasher cleaning system finishes operating, the water distribution control valve 2 switches to the range hood cleaning water pipeline 4 to provide cleaning water to the range hood cleaning system.
[0025] The dishwasher cleaning system also includes a water storage container and a turbidity detection device located at the bottom of the water storage container; the turbidity detection device is used to detect the turbidity of the cleaning water in the water storage container.
[0026] The dishwasher's cleaning system is first introduced through an inlet pipe 20. The inlet pipe 20 is connected to an adjustable inlet valve 21, which controls the rate at which water flows into the system. The water then passes through a breather flow meter 22, which ensures a stable water flow and helps monitor and adjust the flow rate. Next, the water flows into a water softener 23, which reduces the mineral content (such as calcium and magnesium) in the water to prevent scale formation inside the dishwasher.
[0027] The treated water flows into the water storage container 12 (i.e., the water cup), a key component located at the bottom of the dishwasher's inner tub 18. The water storage container 12 not only stores the washing water but also contains a filter screen 14 to filter out any large particles. Furthermore, a turbidity detection device 13 (optionally a turbidity sensor) is installed below the filter screen 14 to monitor the turbidity of the water in the water storage container 12 in real time, thereby determining whether the washing water needs to be changed or an additional washing cycle needs to be performed.
[0028] Water flowing from the water storage container 12 is connected to the washing pump 1, which has a heating function, through an outlet. The washing pump 1 not only provides the necessary water pressure but also heats the water as needed to enhance the cleaning effect. The outlet of the washing pump 1 is connected to the water distribution control valve 2, which is an important distribution component. It has two outlets, one of which directly serves the dishwasher cleaning system, and the other is reserved for use by other systems (such as the range hood cleaning system).
[0029] The water supply line eventually branches into three directions, connecting to the top spray arm 15, the middle spray arm 16, and the bottom spray arm 17, respectively. These spray arms are evenly distributed at different heights inside the dishwasher, ensuring that the dishes are thoroughly rinsed from multiple angles.
[0030] A drain port is designed at the bottom of the water storage container 12, which is directly connected to the drain pump 24 via a dedicated pipe. The function of the drain pump 24 is to draw used wastewater from the water storage container 12 and finally discharge it into the sewer through the external discharge pipe 25. This design ensures that wastewater can be discharged from the dishwasher quickly and effectively, avoiding problems such as low cleaning efficiency or water accumulation inside the machine due to poor drainage.
[0031] The range hood cleaning system mainly includes: a smoke collection chamber (7), a fan assembly (8), multiple spray devices (9), a range hood cleaning water pipeline (4), a steam generator (10), a guide chamber (11), and a wastewater discharge structure. The entire system is designed to automatically clean key components before and after range hood operation, reducing oil buildup and extending equipment lifespan.
[0032] The smoke collection chamber 7 is the core smoke extraction area of the range hood, usually made of metal, which has good high-temperature resistance and corrosion resistance. It forms an airflow channel inside to concentrate and draw in the smoke generated during cooking.
[0033] The impeller assembly 8, located inside the smoke collection chamber 7, is the power core of the range hood. Driven by a motor, it rotates at high speed, using centrifugal force to expel the inhaled fumes to the external duct. Due to prolonged contact with fumes, oil stains easily accumulate on the surface of the impeller assembly 8, affecting smoke extraction efficiency; therefore, it is a key target for cleaning by the cleaning system.
[0034] The range hood cleaning water pipe 4 is a key component connecting the water flow path of the entire cleaning system. One end is connected to the water distribution control valve 2 (from the washing pump 1), and the other end is connected to the steam generator 10 and each spray device 9. Generally, the pipes are made of high-temperature and pressure-resistant materials to ensure a stable supply of steam and hot water. The pipe layout is reasonable, avoiding dead corners and ensuring that the cleaning fluid can cover all critical areas.
[0035] The spray device 9 is a key component of the cleaning system, specifically comprising multiple nozzles or spray pipes located at different positions inside the smoke collection chamber 7. The outlet of the smoke machine cleaning water pipeline 4 is connected to the inlet of these spray devices 9 via fluid distribution fittings 27 (tees, crosses), spraying cleaning liquid or steam for cleaning as needed.
[0036] The first type of spray device 9 is positioned towards the impeller assembly 8 and is used to directly clean oil stains from the impeller surface. The second type of spray device 9 is positioned towards the interior of the smoke collection chamber 7 and is used to clean the inner walls and other areas of the smoke collection chamber 7.
[0037] To improve cleaning efficiency, especially for removing stubborn grease, the system includes a steam generator 10. A spray device 9, positioned towards the impeller assembly 8, is connected to the range hood cleaning water pipe 4 via this steam generator 10. When the cleaning mode is activated, water enters the steam generator 10 and is heated into high-temperature steam, which is then sprayed out through the spray device 9. This high-temperature steam softens and dissolves grease, reducing cleaning time and water consumption, while also preventing mechanical damage to the impeller.
[0038] To achieve effective collection and discharge of wastewater after cleaning, the system has a guide cavity 11 at the bottom of the smoke collection chamber 7. It can collect the wastewater flowing down from the impeller and the inner wall of the smoke collection chamber 7 during the cleaning process, and connect it to the external discharge pipe 25 through the wastewater discharge guide part 52, so that the wastewater can be discharged to the sewer or a centralized recycling device.
[0039] The flow guiding component 5 is a key part of the entire cleaning system responsible for managing and guiding exhaust gas, wastewater and distributing cleaning water. It consists of three main parts: exhaust flow guiding section 51, wastewater discharge flow guiding section 52 and cleaning water connection section 53.
[0040] The exhaust guide section 51 connects the exhaust section 26 of the dishwasher cleaning system to an external exhaust pipe. During the cleaning process, especially when using hot water or steam, hot or humid air is generated. This air needs to be effectively exhausted to avoid damaging the equipment or affecting the internal environment. The exhaust guide section 51 ensures that this exhaust air can be smoothly discharged from inside the machine to the external environment.
[0041] Wastewater discharge diversion section 52 is used to collect and discharge wastewater from the dishwasher cleaning system and the range hood cleaning system. Wastewater generated during both the dishwasher and range hood cleaning processes is directed to this wastewater discharge diversion section 52 and then discharged into the sewer or other designated wastewater treatment facility via the external discharge pipe 25. This helps keep the inside of the equipment dry, preventing bacterial growth and odor generation.
[0042] The cleaning water connection 53 connects the water distribution control valve 2 to the range hood cleaning water pipeline 4. Its function is to ensure that the cleaning water from the washing pump 1 is accurately distributed to the range hood cleaning system, providing the necessary clean water source for the range hood.
[0043] In this embodiment, two flow guiding components 5 (first flow guiding component 5-1 and second flow guiding component 5-2) are included. They each perform different functions and work together to achieve efficient management of exhaust gas and wastewater as well as distribution of cleaning water.
[0044] The exhaust guide section 51 of the first flow guide assembly 5-1 is responsible for connecting the exhaust section 26 of the dishwasher cleaning system to the exhaust guide section 51 in the second flow guide assembly 5-2. The purpose of this design is to centrally process the exhaust gas from the dishwasher and guide it to a comprehensive exhaust gas treatment process.
[0045] The wastewater discharge guide section 52 of the first guide assembly 5-1 is directly connected to the drain pump 24, and then discharges the wastewater generated by the dishwasher to the sewer or other designated location through the external discharge pipe 25. This design ensures that the wastewater after the dishwasher is used can be removed quickly and effectively, preventing internal water accumulation or bacterial growth.
[0046] The cleaning water connection 53 of the first flow guiding assembly 5-1 is used to connect the water outlet of the water distribution control valve 2, which is specifically for supplying water to the range hood cleaning system, and the cleaning water connection 53 of the second flow guiding assembly 5-2. This means that the cleaning water from the washing pump 1 can be accurately delivered to the range hood section that needs cleaning after appropriate diversion.
[0047] After receiving the exhaust gas from the first guide assembly 5-1, the exhaust guide section 51 of the second guide assembly 5-2 further guides the exhaust gas to the condenser 6 located in the smoke collection chamber 7. The function of the condenser 6 is to cool the moisture in the exhaust gas, causing it to condense into liquid, thereby reducing the amount of steam emitted to the outside. The condensate is discharged through the guide chamber 11.
[0048] The wastewater discharge guide section 52 of the second guide assembly 5-2 connects the guide cavity 11 at the bottom of the smoke collection chamber 7 to the wastewater discharge path of the entire system. In this way, wastewater generated during the cleaning process of both the dishwasher and the range hood can be collected uniformly and discharged through the external discharge pipe 25.
[0049] The cleaning water connection 53 of the second flow guiding assembly 5-2 is connected not only to the cleaning water connection 53 in the first flow guiding assembly 5-1, but also further connected to the inlet of the fluid distribution pipe 27. The function of the fluid distribution pipe 27 is to accurately distribute the water flow entering the smoke machine cleaning system, ensuring that each spray device 9 can obtain an appropriate amount of cleaning water, thereby improving cleaning efficiency.
[0050] Example 2 like Figure 5 As shown, this embodiment provides a control method for a cleaning system, applicable to integrated cooking appliances in home or commercial kitchens, including a dishwasher cleaning system, a range hood cleaning system, a water distribution control valve, and a central controller. This method achieves efficient and orderly cleaning operations for the dishwasher and range hood through automated control logic, specifically including the following steps: Step S1: Start the dishwasher cleaning system: After the user selects the dishwasher cleaning program, the control system starts the dishwasher cleaning system and executes the standard cleaning process, including water intake, spraying, washing, heating, and drainage.
[0051] Step S2: The range hood cleaning system is automatically activated after the dishwasher cleaning system finishes its cycle. Once the dishwasher completes its current cleaning cycle and confirms the system is fault-free, the control system automatically triggers the range hood cleaning program. This method ensures continuous cleaning operations, improves user convenience, and optimizes equipment resource scheduling.
[0052] Specifically, this also includes the coordinated control of the water distribution control valve: after the dishwasher completes its cleaning cycle, the control system sends a switching command to the water distribution control valve, controlling it to switch from the dishwasher's cleaning water line to the range hood's cleaning water line, ensuring that the cleaning water can flow smoothly to the range hood's cleaning system. Once the water supply pressure and flow rate are stable, the control system confirms that the water supply is normal and officially starts the range hood's cleaning program.
[0053] Periodic start control of the range hood cleaning system: After the range hood completes one cleaning cycle, the control system activates the timing module. After a preset time interval (such as 2 days, 3 days, or a user-defined period), the control system determines whether the conditions for restarting the cleaning program are met. If the conditions are met, the range hood cleaning system is automatically started to perform a basic cleaning operation. If the range hood is currently running or a user-defined period during which cleaning is prohibited, the control system postpones the cleaning operation to a suitable time.
[0054] This control method achieves intelligent switching of water circuits through a water distribution control valve, reducing pipeline redundancy and improving system integration. At the same time, through a periodic cleaning mechanism, it can effectively reduce the risk of oil buildup in the range hood, extend equipment life, and improve equipment operating efficiency.
[0055] Preferably, the water distribution control valve is an electrically controlled valve, and its switching process is automatically controlled by the central controller according to the cleaning program status, or it can be switched manually by the user. The preset time interval can be set by the user through the control panel or mobile terminal, and the system supports multiple cycle selections.
[0056] Example 3 like Figure 6 As shown, this embodiment provides a control method for a cleaning system, applicable to integrated cooking appliances in home or commercial kitchens that include a dishwasher cleaning system, a range hood cleaning system, a water storage container, a water distribution control valve, a turbidity sensor, and a central controller. This method intelligently determines the water quality status of the cleaning water, automatically selects the cleaning target, and controls the water path switching, achieving efficient water resource utilization and automated equipment cleaning.
[0057] Step M1: After the system starts, the turbidity of the cleaning water in the storage container is first detected by a turbidity detection device (turbidity sensor can be used), and the detected turbidity value is compared with a preset turbidity threshold. This preset turbidity threshold can be set according to the water quality requirements of different cleaning equipment, such as a value between 0.5 and 5 for the NTU value.
[0058] While detecting the turbidity of the cleaning water in the storage container, the control system also activates the wash pump in the dishwasher cleaning system to preheat the cleaning water. The wash pump has a heating function and can be shared between the dishwasher cleaning system and the range hood cleaning system.
[0059] The purpose of preheating is to increase the temperature of the cleaning water, thereby enhancing the efficiency of oil removal during subsequent cleaning processes and improving the overall cleaning effect. The preferred preheating temperature is between 40℃ and 60℃, and the specific temperature can be dynamically adjusted according to the type of cleaning task and water quality.
[0060] Step M2: If the turbidity of the cleaning water is less than or equal to the preset turbidity threshold, it indicates that the water quality is good and suitable for direct supply to the range hood cleaning system. The control system will then start the range hood cleaning program.
[0061] Step M3: If the turbidity of the cleaning water exceeds the preset turbidity threshold, it indicates poor water quality and is unsuitable for direct use in cleaning the range hood. At this point, the control system will activate the dishwasher cleaning system to circulate and filter the cleaning water, reducing its turbidity. Once the turbidity of the cleaning water decreases to less than or equal to the preset turbidity threshold, the range hood cleaning system will be activated again.
[0062] This control method enables intelligent judgment and graded use of cleaning water, improving water resource utilization while avoiding the impact of poor water quality on cleaning equipment.
[0063] After the control system determines the turbidity of the cleaning water, it will automatically control the water distribution control valve to switch to the corresponding cleaning water pipeline according to the type of cleaning task. Specifically: When the preset threshold for turbidity of the cleaning water is less than or equal to the preset threshold for turbidity: the control system controls the water distribution control valve to switch to the connection of the range hood cleaning water pipeline, ensuring that the cleaning water can flow smoothly to the range hood cleaning system, thereby starting the range hood cleaning program.
[0064] When the preset threshold for turbidity of the cleaning water is greater than the preset threshold for turbidity: the control system controls the water distribution control valve to switch to the cleaning water pipeline connected to the dishwasher, ensuring that the cleaning water enters the dishwasher cleaning system for circulation and filtration treatment to reduce the turbidity of the water.
[0065] The water distribution control valve is preferably an electric control valve. Its switching process is automatically controlled by the central controller according to the cleaning program status and water quality test results, or it can be switched manually by the user.
[0066] Through the above control methods, the system realizes intelligent water circuit allocation for the dishwasher and range hood cleaning system, which improves cleaning efficiency, reduces system complexity, and enhances the intelligence level of the equipment.
[0067] When the cleaning water quality is poor, starting the dishwasher cleaning system first ensures that the water used for the range hood cleaning system is clean. There are several reasons for this. First, running the dishwasher effectively removes most impurities and contaminants from the water (the dishwasher's water reservoir has a filter in the middle that traps impurities and contaminants, resulting in better-quality water exiting from the bottom of the reservoir). This ensures that the water supplied to the range hood cleaning system is clean, improving the cleaning effect and preventing incomplete cleaning due to water quality issues. Second, the range hood cleaning system uses small-diameter water pipes, which are prone to clogging if the water contains many impurities or particles. Pre-filtering and circulating the water through the dishwasher reduces impurities, lowers the risk of clogging, and ensures smooth water flow. Third, the steam generator in the range hood cleaning system requires relatively pure water to produce high-temperature steam, enhancing its cleaning ability for internal components. Using water containing impurities can cause deposits to accumulate inside the steam generator, affecting its efficiency and shortening its lifespan. Therefore, purifying the water with a dishwasher system first can protect the steam generator from damage and maintain its long-term efficient operation.
[0068] In conclusion, when the water quality is poor, using the dishwasher's cleaning system first not only purifies the water, ensuring a more effective cleaning of the range hood system, but also prevents pipe blockages and protects critical components such as the steam generator, extending their lifespan. The ultimate goal is to maintain the performance and reliability of the entire integrated cooking and washing center, providing a better user experience.
