Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a cleaning system and an integrated cooking device. Background Technology

[0002] In modern family kitchens, dishwashers and range hoods are widely used as essential cleaning appliances in daily life. Dishwashers automatically clean dishes using a spray system, while range hoods remove cooking fumes and regularly clean their internal impellers and cavities to maintain their smoke extraction efficiency and hygiene. However, in traditional technology, dishwashers and range hoods are usually equipped with independent cleaning systems, including separate water pumps, inlet valves, piping systems, and drainage structures. This not only results in complex equipment structures and large space requirements but also low water and energy efficiency and inconvenient system maintenance.

[0003] Furthermore, existing dishwasher cleaning systems primarily focus on cleaning the surface of tableware, while range hoods have complex internal structures where grease easily adheres to the impeller, inner walls, and other parts. Traditional cleaning methods often involve manual disassembly or simple spraying, resulting in limited cleaning effectiveness and making it difficult to achieve efficient and automated cleaning. Additionally, the wastewater discharge from the two systems is usually independent, lacking a unified flow and discharge design, which can easily lead to poor drainage or secondary pollution problems.

[0004] Therefore, there is an urgent need to provide a cleaning system that is structurally sound, highly integrated, efficient, energy-saving, and environmentally friendly to solve the above problems and meet the development needs of modern intelligent kitchen equipment. Summary of the Invention

Figure 5 This is a schematic diagram of an integrated cooking device according to an exemplary embodiment. The above schematic diagram is only for illustrating the structural relationships related to the inventive point and is not intended as an actual scale of a product.

[0023] Example 1 like Figures 1 to 4 As shown, a cleaning system according to an embodiment of the present invention includes: a dishwasher cleaning system, a range hood cleaning system, a washing pump 1, and a water distribution control valve 2; the dishwasher cleaning system includes a dishwasher cleaning water pipeline 3 for supplying cleaning water to the dishwasher; the range hood cleaning system includes a range hood cleaning water pipeline 4 for supplying cleaning water to the range hood; the outlet of the washing pump 1 is connected to the dishwasher cleaning water pipeline 3 and the range hood cleaning water pipeline 4 respectively through the water distribution control valve 2.

[0024] 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.

[0025] 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.

[0026] 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).

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] Example 2 like Figure 5 As shown, an integrated cooking device includes a cooktop system 19 and a cleaning system as described in Embodiment 1.
