Description

Technical Field

[0001] This utility model relates to the field of range hoods, and in particular to a wind energy recycling mechanism for self-cleaning range hoods. Background Technology

[0002] Most existing range hoods have self-cleaning functions, but these functions mainly focus on cleaning the turbine housing and the impeller inside. By heating the turbine housing, the impeller is also heated, accelerating the softening and separation of grease on the inner wall of the turbine housing and the impeller, thus achieving a self-cleaning effect. However, the self-cleaning effect is often not achieved for the smoke outlet at the top of the range hood. The grease that accumulates on the inner wall of the smoke outlet is prone to clogging and is very difficult to clean. At the same time, cleaning the working surface of the range hood often requires users to use steam heating to heat the outer shell, soften the grease, and then wipe it clean with a scouring pad, which is also a cumbersome operation. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a wind energy recycling mechanism for a range hood that can heat the smoke outlet, accelerate the decomposition of grease inside the smoke outlet, reduce the risk of blockage in the smoke outlet pipe of the range hood, and automatically steam clean the working surface of the range hood.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] A self-cleaning wind energy recycling mechanism for a range hood includes a water pump and an evaporator fixed on the top of the range hood, with the water outlet of the water pump connected to the water inlet of the evaporator.

[0006] The evaporator's outlet is connected to two steam pipes. The ends of the two steam pipes furthest from the evaporator are both wrapped around the range hood's exhaust port and extend through the range hood's outer casing to the inner side of the casing, facing the range hood's exhaust port.

[0007] Preferably, a pipe distributor is fixed at the top of the range hood, directly opposite the evaporator. The air inlet of the pipe distributor is connected to the air outlet of the evaporator, and the air inlets of the two steam pipes are respectively connected to the two air outlets of the pipe distributor.

[0008] Preferably, the steam pipe has a spiral portion forming around the flue gas outlet on the outside of the outlet, and the spiral portion is attached to the outer wall of the outlet.

[0009] Preferably, the spiral section of the steam pipe is made of non-insulated pipe material, while the straight section of the steam pipe away from the evaporator is made of insulated pipe material.

[0010] Preferably, a heat insulation cover is fixed to the top of the range hood outside the smoke outlet. The heat insulation cover covers the two spiral parts, and both ends of the spiral parts extend through the heat insulation cover to the outside of the heat insulation cover.

[0011] Preferably, in the two spiral sections of the steam pipes, one spiral section is fitted into the spiral spacing of the other spiral section.

[0012] Preferably, a condensate box is fixed to one side of the inner wall of the outer casing near the end of the straight pipe extending into the inner side of the outer casing, and the condensate box is located directly below the end of the straight pipe extending into the inner side of the outer casing.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] By setting up an evaporator and a water pump, the water pump introduces water into the evaporator to generate high-temperature steam during operation, which heats the flue gas outlet through the steam pipe. This accelerates the decomposition of grease in the outlet, reduces the probability of grease condensing in the outlet, and thus reduces the risk of blockage in the flue gas outlet pipe.

[0015] When the exhaust port is heated, the internal temperature of the exhaust pipe rises, which helps the fumes flow and be discharged faster, reducing the residence time of the fumes in the pipe. The high temperature can also accelerate the movement of the fume molecules, making them easier to be discharged outdoors, thereby improving the exhaust efficiency of the range hood.

[0016] The generated high-temperature water vapor reaches the inner side of the outer shell and is then carried by the wind power of the range hood to the outer wall of the working surface of the range hood. This achieves the effect of cleaning the working surface of the range hood by circulating the wind power of the range hood and guiding the water vapor. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1 to 6 This embodiment provides a self-cleaning wind energy recycling mechanism for a range hood, including a water pump 1 and an evaporator 2 fixed on the top of the range hood 100. The water outlet of the water pump 1 is connected to the water inlet of the evaporator 2. A pipe diverter 3 is fixed on the top of the range hood 100 directly opposite the evaporator 2. The air inlet of the pipe diverter 3 is connected to the air outlet of the evaporator 2. Both air outlets of the pipe diverter 3 are connected to a steam pipe 4. The steam pipe 4 has a spiral part 401 and a straight pipe part 402. The spiral part 401 surrounds and fits around the outer wall of the smoke outlet 1002 of the range hood 100. One spiral part 401 is embedded in the spiral spacing of the other spiral part 401. The straight pipe part 402 penetrates the outer shell 1001 of the range hood 100 and extends to the inner side of the outer shell 1001 facing the smoke inlet 1003 of the range hood 100.

[0026] Water pump 1 is connected to a water source and pumps water to the evaporator 2. The water is heated by the evaporator 2 to form high-temperature steam. The high-temperature steam is then split into two streams by the pipe splitter 3 and enters two steam pipes 4 respectively. Heat is released at the spiral part 401 of the steam pipe 4 to heat the flue gas outlet 1002.

[0027] It can accelerate the decomposition of grease in the smoke outlet 1002, reduce the probability of grease condensing in the smoke outlet 1002, thereby reducing the risk of blockage in the smoke outlet pipe. The internal temperature of the heated smoke outlet pipe rises, which helps the fumes flow and be discharged faster, and reduces the residence time of the fumes in the pipe.

[0028] Then, the straight pipe section 402 enters the inner side of the outer casing 1001 and faces the smoke inlet 1003 of the range hood 100, thereby steam heating and cleaning the working surface of the range hood 100. Then, the cleaning work can be completed by wiping the working surface of the range hood 100 with a scouring pad.

[0029] The spiral part 401 is made of non-insulated pipe material, and the straight pipe part 402 is made of insulated pipe material. The top of the range hood 100 is fixed with an insulation cover 5 outside the smoke outlet 1002. The insulation cover 5 covers the two spiral parts 401, and both ends of the spiral part 401 extend through the insulation cover 5 to the outside of the insulation cover 5.

[0030] This allows the steam to dissipate heat at the flue outlet 1002 and heat the flue outlet 1002. The spiral part 401 is insulated by the heat insulation cover 5 to reduce heat dissipation. The straight pipe part 402 uses heat-insulating pipe material to reduce the amount of steam dissipating heat at the straight pipe part 402.

[0031] A condensate box 6 is fixed to one side of the inner wall of the outer casing 1001 near the end of the straight pipe section 402 extending into the inner side of the outer casing 1001. The condensate box 6 is located directly below the end of the straight pipe section 402 extending into the inner side of the outer casing 1001. In use, if only the smoke outlet 1002 needs to be heated, the temperature setting of the evaporator 2 can be set to a lower level. Only the smoke outlet 1002 needs to be heated. Subsequently, the steam forms condensate and is discharged from the end of the straight pipe section 402 and collected by the condensate box 6. When it is necessary to clean the working surface of the range hood 100 at the same time, the temperature setting of the evaporator 2 is increased, and steam is sprayed from the end of the straight pipe section 402 onto the working surface of the range hood 100.

[0032] Magnets can be fixed to the outer wall of the condensate box 6, thereby magnetically securing the condensate box 6 to the outer casing 1001.

[0033] After the generated high-temperature water vapor reaches the inside of the outer casing 1001, it is driven by the wind power of the range hood 100 to the outer wall of the working surface of the range hood 100 under the action of the wind power of the range hood 100, thereby achieving the effect of cleaning the working surface of the range hood 100 by circulating the wind power of the range hood 100 and guiding the water vapor.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
