[0010] An oil cleaning device, comprising:

[0011] The oil drain pipe is used to collect the oil produced by the range hood;

[0012] A water storage tank connected to a concentrated water pipe, wherein the concentrated water pipe is connected to a water purifier and is used to input concentrated water produced by the water purifier into the water storage tank;

[0019] Beneficial effects of the utility model:

[0020] 1. By extending the spray structure into the oil drain pipe, the cleaning water is sprayed directly from the spray hole onto the inner wall of the oil drain pipe, and the oil stains attached to the inner wall are cleaned and flushed, which can directly and efficiently remove the oil stains in the oil drain pipe and avoid the oil drain pipe being blocked by oil stains;

[0021] 2. The structure of the spray ring makes each spray hole close to the corresponding inner wall of the oil drain pipe, shortening the spray distance between the spray hole and the inner wall of the oil drain pipe, thereby ensuring that the cleaning water sprayed from the spray hole has sufficient flushing force on the inner wall of the oil drain pipe, thereby improving the cleaning ability of the cleaning water on the oil stains attached to the inner wall of the oil drain pipe;

[0022] 3. The spray hole is located closest to the inner wall of the oil drain pipe and can ensure the water pressure strength of the spray hole to improve the cleaning and flushing effect;

[0023] 4. By gradually reducing the diameter of the boosting section along the output direction of the cleaning water, the water flow is constrained at the boosting section, and the flow rate per unit area is increased, achieving the purpose of local boosting, thereby making the impact force of the spray structure spray greater, thereby improving the cleaning and flushing effect on the inner wall of the oil drain pipe;

[0024] 5. The oil cleaning device uses the concentrated water produced by the water purifier, stores the concentrated water in the water storage tank as the source of cleaning water, and cleans the oil discharge pipe through the cleaning pipe. It can not only directly clean the oil produced by the range hood, but also is more convenient than setting up an oil collection box to collect the oil from the range hood. It also uses concentrated water for cleaning to reduce the waste of water resources.

[0025] 6. The water supply pipe inputs tap water into the water storage tank. When the concentrated water of the water purifier is not enough to clean the oil drain pipe, tap water is added to the water storage tank through the water supply pipe. Therefore, the water source of the water storage tank includes concentrated water and tap water;

[0026] 7. By setting up a water level monitoring mechanism, the preset minimum water level and preset maximum water level of the water tank are monitored, thereby providing judgment conditions for cleaning and water replenishment, and improving the degree of intelligence;

[0027] 8. The water supply pipe, water inlet pipe and tap water pipe are connected in parallel by setting a three-way valve, thereby simplifying the structural setting;

[0028] 9. The overflow pipe plays an overflow role. When the water level monitoring mechanism is abnormal or fails and the water level in the water tank rises to the overflow pipe, the water can be discharged from the overflow pipe to the adapter;

[0029] 10. The setting of the air pressure balance hole can prevent the imbalance of internal and external air pressure due to water level changes in the water tank. If the water tank is closed and has no exhaust facilities, the water tank may be deformed or damaged due to the compression of internal air during the water filling process; and when draining water, a vacuum state may occur, making it difficult for water to be discharged smoothly.

[0038] A spray mechanism, referring to Figure 1-3 , including a cleaning pipe 4, the cleaning pipe 4 provides cleaning water, the cleaning pipe 4 is provided with a spray structure 41, the spray structure 41 extends into the interior of the oil drain pipe 2, and the spray structure 41 is located at the upper part of the oil drain pipe 2, thereby expanding the cleaning coverage of the spray structure 41 on the oil drain pipe 2, and a spray hole 4a is provided on the spray structure 41, the spray direction of the spray hole 4a points to the inner wall of the oil drain pipe 2 and is inclined downward, thereby increasing the flushing intensity of the spray hole 4a, the cleaning water in the cleaning pipe 4 is transported to the spray structure 41, and is sprayed on the inner wall of the oil drain pipe 2 through the spray hole 4a, thereby cleaning the oil stains along the inner wall of the oil drain pipe 2.

[0039] The spray mechanism of this embodiment is used to clean the oil stains in the oil drain pipe 2, and in particular, the spray mechanism of this embodiment is used to clean the oil stains generated by the oil drain pipe 2 and the range hood. In this embodiment, by extending the spray structure 41 into the oil drain pipe 2, the cleaning water is sprayed directly from the spray hole 4a onto the inner wall of the oil drain pipe 2, and the oil stains attached to the inner wall are cleaned and flushed, so that the oil stains in the oil drain pipe 2 can be directly and efficiently removed to prevent the oil drain pipe 2 from being blocked by the oil stains.

[0040] In this embodiment, the spray structure 41 includes a spray ring 411, and the outer ring surface 4111 of the spray ring 411 is close to the inner wall of the oil drain pipe 2, that is, in terms of structural shape, the shape of the spray ring 411 is adapted to the cross-sectional shape of the oil drain pipe 2, and the spray holes 4a are arranged along the circumference of the spray ring 411. The structural setting of the spray ring 411 makes each spray hole 4a close to the corresponding inner wall position of the oil drain pipe 2, shortening the spray distance of the spray hole 4a to the inner wall of the oil drain pipe 2, thereby ensuring that the cleaning water sprayed from the spray hole 4a has sufficient flushing force on the inner wall of the oil drain pipe 2, thereby improving the cleaning ability of the cleaning water to the oil stains attached to the inner wall of the oil drain pipe 2.

[0041] In this embodiment, the spray hole 4a is arranged on the chamfered surface 4113 of the spray ring 411, and the chamfered surface 4113 connects the outer ring surface 4111 and the bottom surface 4112, so that the spray direction of the spray hole 4a points to the inner wall of the oil drain pipe 2 and tilts downward, and can ensure the water pressure strength of the water outlet of the spray hole 4a to improve the cleaning and flushing effect.

[0042] The spray structure 41 of the present embodiment also includes a connector, which connects the spray ring 411 and the cleaning pipe 4.

[0043] In this embodiment, the spray structure 41 is located at the top of the oil drain pipe 2, so that the cleaning and flushing range of the spray structure 41 covers the entire inner wall of the oil drain pipe 2, which is the optimal solution.

[0044] Implementation Case 2:

[0045] An oil cleaning device, referring to Figure 4, including an oil drain pipe 2 and a water storage tank 1. The oil drain pipe 2 is used to converge the oil stains generated by the range hood. The water storage tank 1 is connected to a concentrated water pipe 3 and a cleaning pipe 4, wherein the concentrated water pipe 3 is connected to a water purifier 6. The part of the concentrated water pipe 3 connected to the water purifier 6 has a pump, so that the concentrated water pipe 3 can transport the concentrated water generated in the water purifier 6 to the water storage tank 1. The cleaning pipe 4 is equipped with a water pump 42, and uses the water storage tank 1 as a water source for cleaning water, outputs the cleaning water to the oil drain pipe 2 to clean the oil stains in the oil drain pipe 2, and the cleaning pipe 4 and the spray structure 41 provided in the cleaning pipe 4 constitute the spray mechanism of implementation case 1.

[0046] The concentrated water produced by the water purifier 6, also known as wastewater or concentrated water, is formed during the reverse osmosis RO or other types of deep water treatment processes. When the water purifier 6 is working, especially the water purifier using reverse osmosis membrane technology, the raw water is filtered through the RO membrane under high pressure. Since the RO membrane can intercept most of the pollutants such as soluble solids, organic matter, microorganisms, viruses, heavy metal ions, etc., only water and some small molecules are allowed to pass through to become pure water that can be directly drunk, and those parts that fail to pass through the RO membrane and contain higher concentrations of pollutants form concentrated water. The concentrated water contains a high TDS total dissolved solids and other harmful substances that are filtered out, so it is not suitable for drinking, nor for cooking and other uses involving human intake. However, concentrated water, as a clean water source, can be used for cleaning or irrigation. The oil cleaning device of this embodiment utilizes the concentrated water produced by the water purifier 6, and stores the concentrated water in the water storage tank 1 as a source of cleaning water. The oil drain pipe 2 is cleaned with the cleaning pipe 4. It can not only directly clean the oil generated by the range hood, which is more convenient than setting up an oil collecting box to collect the oil from the range hood, but also uses concentrated water for cleaning to reduce the waste of water resources.

[0047] In this embodiment, the water tank 1 is connected to a water supply pipe 51, which inputs tap water into the water tank 1. When the concentrated water in the water purifier 6 is not enough to clean the oil drain pipe 2, tap water is added to the water tank 1 through the water supply pipe 51. Therefore, the water source of the water tank 1 includes concentrated water and tap water.

[0048] In this embodiment, a water level monitoring mechanism is provided in the water tank 1, and the water level monitoring mechanism can monitor the preset minimum water level and preset maximum water level in the water tank 1. The water tank 1 supplements the concentrated water produced by the water purifier 6 through the concentrated water pipe 3 as the water source for cleaning the oil drain pipe 2. When the water level monitoring mechanism detects that the amount of water in the water tank 1 has reached the preset maximum water level, it means that the water source in the water tank 1 is sufficient, and the water pump 42 starts to extract the water in the water tank 1 as cleaning water, and outputs it through the cleaning pipe 4 to clean the oil drain pipe 2. That is, the preset maximum water level monitored by the water level monitoring mechanism is used to provide the judgment condition for cleaning the oil drain pipe 2. When the water level monitoring mechanism detects that the amount of water in the water tank 1 has reached the preset minimum water level, it means that the water source in the water tank 1 is insufficient, and tap water is input into the water tank 1 through the water supply pipe 51 for water supply. When the water level in the water tank 1 reaches the preset maximum water level, the water supply of the water supply pipe 51 is stopped, that is, the preset minimum water level monitored by the water level monitoring mechanism is used to provide the judgment condition for replenishing tap water. It should be noted that, under normal circumstances, the oil cleaning device of this embodiment is automatic cleaning for the oil discharge pipe 2, and the automatic cleaning is started when the concentrated water is continuously input into the water tank 1 to reach the preset maximum water level. Therefore, when the automatic cleaning mode is adopted, the water level in the water tank 1 will not drop to the preset minimum water level. However, when the user needs to use the water source of the water tank 1 to clean the oil discharge pipe 2, manually starting the water pump 42 to continuously extract the water source in the water tank 1 will cause the water level in the water tank 1 to drop continuously, until it drops to the preset minimum water level, and the water supply mechanism of automatically opening the water supply pipe 51 to replenish tap water.

[0049] In the present embodiment, the water level monitoring mechanism is more specifically comprised of a buoyancy member (not shown in the figure), an upper water level sensor 12, and a lower water level sensor 13, wherein the buoyancy member is disposed in the water storage tank 1 and floats on the water surface, the upper water level sensor 12 and the lower water level sensor 13 can be disposed on the wall of the water storage tank 1, the upper water level sensor 12 is used to sense the buoyancy member at a preset maximum water level, and the lower water level sensor 13 is used to sense the buoyancy member at a preset minimum water level.

[0050] In this embodiment, the water supply pipe 51 is provided with a solenoid valve 511, and the water supply pipe 51 is connected to a three-way valve 52, and the other two connection ends of the three-way valve 52 are respectively connected to a tap water pipe 53 and a water inlet pipe 54, wherein the tap water pipe 53 is used to supply tap water, i.e., municipal water, and the water inlet pipe 54 is connected to the water purifier 6 for inputting tap water into the water purifier 6, and the part of the water inlet pipe 54 connected to the water purifier 6 has a pump, and when the water purifier 6 needs to be replenished with water, the pump can be turned on to replenish water, and when it is not necessary to replenish tap water to the water storage tank 1, the solenoid valve 511 is in a closed state, and when it is necessary to replenish water, the solenoid valve 511 can be opened. By setting the three-way valve 52, the water supply pipe 51, the water inlet pipe 54 and the tap water pipe 53 are connected in parallel, thereby simplifying the structural setting.

[0051] In this embodiment, the oil drain pipe 2 is connected to an adapter 7, which is a tubular structure and is used to discharge the oil from the oil drain pipe 2 into the sewer, and is also used as a discharge tool for other kitchen emissions. An overflow pipe 8 is connected between the water tank 1 and the adapter 7. The level of the overflow pipe 8 connected to the water tank 1 is higher than the preset maximum water level. The overflow pipe 8 plays an overflow role. When the water level monitoring mechanism is abnormal or fails and the water level in the water tank 1 rises to the overflow pipe 8, water can be discharged from the overflow pipe 8 to the adapter 7.

[0052] In this embodiment, the horizontal height of the overflow pipe 8 connected to the adapter 7 is higher than the horizontal height of the oil drain pipe 2 connected to the adapter 7, so that the water discharged from the overflow pipe 8 can clean the oil discharged into the adapter 7, thereby preventing the oil from adhering to the inner wall of the adapter 7.

[0053] In this embodiment, an air pressure balance hole 14 is provided on the top of the water tank 1. The setting of the air pressure balance hole 14 can prevent the imbalance of the internal and external air pressures of the water tank 1 due to changes in the water level. If the water tank 1 is closed and has no exhaust facilities, the water tank may be deformed or damaged due to the compression of the internal air during the water filling process; and when draining the water, a vacuum state may occur, making it difficult for the water to be discharged smoothly.

[0054] Implementation Case 3:

[0055] An integrated stove includes an oil cleaning device, and the oil cleaning device is shown in Implementation Case 2.

[0056] In this embodiment, the oil drain pipe 2 is connected to the range hood of the integrated stove, and the water storage tank 1 and the water purifier 6 are arranged under the stove top of the integrated stove.

[0057] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
