[0002] In the modern catering industry, the application of high-temperature cooking equipment such as barbecue ovens and fryers is becoming more and more widespread. These equipment will produce a large amount of oil smoke and high-temperature gas during the cooking process. In order to effectively deal with these oil smoke and ensure the cleanliness and hygiene of the kitchen environment, water-transporting hoods have been widely used as an efficient oil smoke purification device. Traditional oil-net hoods have problems such as unstable grease filtration and easy clogging in high-temperature environments.

The purified oil smoke is extracted from the exhaust port 120, and the water mist flows downward in the shell 1 and is collected in the water storage area 151; the water in the water storage area 151 is pumped into the return water tank 10 through the return pipe 4, and the water in the return water tank 10 is transported to the spray mechanism 2 in the water transport device through the water inlet pipe 3 again, so as to realize the recycling of water resources; when the waste water that cannot be recycled after multiple uses needs to be discharged, the waste water in the water storage area 151 is pumped out by the water pump through the drain pipe 5. This embodiment realizes that water can be discharged upward smoothly under the influence of limited kitchen floor height or other environmental factors, solves the problem that the traditional downward drainage method cannot be applied, and improves the adaptability and flexibility of the water transport hood.

[0045] See attached Figure 2 and attached Figure 3In the above embodiment, an upper spraying area 131 and a lower spraying area 141 are formed in the vertical direction in the housing 1, and the spraying mechanism 2 includes an upper spraying pipe 210 located in the upper spraying area 131 and a lower spraying pipe 220 located in the lower spraying area 141, and the air inlet 110 is located above the upper spraying area 131, and the air inlet 110 is close to the lower spraying area 141. In the embodiment, when the oil fume enters the housing 1 from the air inlet 110, it first passes through the lower spraying area 141 and is sprayed with water mist by the lower spraying pipe 220, and then enters the upper spraying area 131 upward and is sprayed with water mist by the upper spraying pipe 210.

In the embodiment, after the tap water of the tap water pipe 7 enters the tee 6, since the first return water section 410 is provided with a check valve 411, the tap water can only be transported to the return water tank 10 through the second return water section 420, realizing the function of replenishing fresh water source into the return water tank 10, and when the drain pipe 5 is used to discharge the water in the water storage area 151 at the same time, the self-cleaning ability of the equipment is realized in combination with the fresh water source replenishment of the tap water pipe 7.

[0050] See attached Figure 2 In the above embodiment, the tap water pipe 7 is provided with a ball valve switch 710, and a third solenoid valve 720 is further provided between the ball valve switch 710 and the three-way member 6. In the embodiment, the ball valve switch 710 is used to mechanically control the supply switch of tap water, and the third solenoid valve 720 is used to electronically control the supply amount of tap water, thereby improving the automation level of the equipment.

[0051] See attached Figure 2 In the above embodiment, a water level detection probe 8 is provided in the water storage area 151. In the embodiment, there are three water level detection probes 8, which are divided into a maximum water level probe, a basic water level probe and a minimum water level probe according to the water level detected. When the water in the water storage area 151 reaches the maximum water level probe, it means that the water should be pumped out through the drain pipe 5; when the water in the water storage area 151 is lower than the minimum water level probe, it means that the drainage of the drain pipe 5 should be stopped and fresh tap water should be supplemented; when the water in the water storage area 151 reaches the basic water level probe, it means that the supplement of fresh tap water should be stopped, and the equipment enters the working state of water resource recycling.

[0052] See attached Figure 4 The present embodiment further provides a water transport hood, comprising a hood body 9 and the above-mentioned upper water discharge water transport device, wherein the upper water discharge water transport device is arranged in the hood body 9. In the embodiment, the hood body 9 is circular, and the lower part is concave for collecting oil smoke, and the collected oil smoke enters from the air inlet 110 of the water transport device and is purified, and finally is extracted from the exhaust port 120.

[0053] See attached Figure 5The present embodiment also provides an upper drainage water transport system, including a return water tank 10 and the above-mentioned water transport hood, and also includes: a return water pump 11 connected to the return water pipe 4, used to pump up the water in the water storage area 151 and transport it to the return water tank 10; a water inlet pump 12 connected to the water inlet pipe 3, used to pump up the water in the return water tank 10 and transport it to the hood to purify the oil fume through the spray mechanism 2; a drainage pump 13 connected to the drainage pipe 5, used to pump up and discharge the water in the water storage area 151. In the embodiment, the water inlet pump 12 sucks the circulating water from the return water tank 10 into the spray mechanism 2 of the hood body 9, and the water mist sprayed by the spray mechanism 2 is collected by the water storage area 151 of the water transport device. When the third solenoid valve 720 is closed, the water in the tap water pipe 7 cannot enter the return water pipe 4. When the return water pump 11 is working, the water in the water storage area 151 will enter the return water tank 10 through the return water pipe 4. When fresh tap water is needed, open the third solenoid valve 720, and the water in the tap water pipe 7 enters the return water pipe 4. Due to the presence of the check valve 411, the tap water can only be transported to the return water tank 10. When the water level in the water storage area 151 is too high or the circulating water is no longer suitable for recycling, the waste water can be discharged from the water storage area 151 through the drainage pipe 5 by the drainage pump 13. By constructing an upper drainage and water transportation system including a return water tank, a water transportation hood, a return water pump, a water intake pump and a drainage pump, the recycling and efficient management of water resources are realized, the operating cost is reduced, and the overall performance and reliability of the system are improved. At the same time, the collaborative work between the various components makes the operation of the system simpler and faster, and improves the user experience.

[0054] In summary, the present embodiment provides an upper drainage water transport device, a smoke hood and an upper drainage water transport system. By setting an upwardly connected return pipe 4 and a drainage pipe 5 to cooperate with a water pump to pump out the water from the water storage area 151, it is achieved that when the kitchen floor height is limited or other environmental factors are affected, the water can be smoothly discharged upward, solving the problem that the traditional downward drainage method cannot be applied; by setting an upper spray area 131 and a lower spray area 141 in the shell 1, and configuring corresponding upper spray pipes 210 and lower spray pipes 220, the oil smoke can pass through multiple layers of water mist spray during the flow process, thereby improving the efficiency and quality of oil smoke purification. ; By setting the first solenoid valve 211 and the second solenoid valve 221, precise control of the spray mechanism 2 is achieved; by setting the check valve 411, backflow is avoided; by setting the three-way piece 6 and connecting the tap water pipe 7, the fresh water source is supplemented; by setting the third solenoid valve 720, it is convenient to control the supply of tap water; by setting the water level detection probe 8, it is convenient to monitor the water level in the water storage area 151; this embodiment can overcome the limitations of the traditional downward drainage method while maintaining a high-efficiency oil fume purification effect, meet the needs of different kitchen environments, and improve the applicability and flexibility of the water transport hood.
