Description

Technical Field

[0001] This utility model relates to the field of range hood impellers, and specifically to a range hood impeller oil-coating device. Background Technology

[0002] The impeller of a range hood is one of its core components, primarily responsible for generating suction, accelerating airflow, separating grease and smoke, and balancing air pressure. During use, when the impeller accumulates too much grease, it can lead to decreased suction, increased energy consumption, increased noise, and poor smoke extraction. Therefore, cleaning the impeller is essential. High-temperature steam cleaning or high-temperature water washing works by using a high-pressure water pump to directly spray water onto the impeller, or by first heating the water with an instant heating element before spraying it onto the impeller. After rinsing, the impeller rotates and dries, ultimately achieving self-cleaning of the range hood. However, in experiments testing cleaning effectiveness, the grease on the impeller needs to be manually and evenly applied, which is difficult and cannot achieve accurate and uniform grease distribution. Currently, there is a need to design a method that can effectively coat the impeller with grease to solve these problems. Utility Model Content

The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0022] Example

[0023] like Figure 1 As shown in the figure, this application provides an oil-collecting device for a range hood impeller, including a bracket 1; the bracket 1 is provided with an oil tank 2, a heating device 3, a lifting screw, a rotating frame 5, and a rotating motor; the impeller 6 is detachably installed on the rotating frame 5; the oil tank 2 is located below the rotating frame 5 and is open at the top; the rotating frame 5 is rotatably installed on the lifting screw, which drives the rotating frame 5 to move along the height direction so that part of the impeller 6 enters the oil tank 2; the heating device 3 is used to heat the oil in the oil tank 2; the rotating frame 5 is provided with a weight sensor 8 for sensing the weight of the range hood impeller 6; the bracket 1 is provided with a position sensor 7 for sensing the height of the lifting screw.

[0024] The lifting screw includes a screw 10, a mounting base 11, and a screw motor 4. One end of the screw 10 is connected to the rotating frame 5. The mounting base 11 is rotatably mounted on the bracket 1 via bearings. The threaded hole of the mounting base 11 matches the thread of the screw 10, and the length direction of the threaded hole is consistent with the height direction. The end of the screw 10 away from the rotating frame 5 passes through the threaded hole. The screw motor 4 drives the mounting base 11 to rotate, thereby driving the screw 10 to move along the length direction of the threaded hole. Optionally, two slide rods 12 are also included. The lifting screw is located in the middle of the rotating frame 5, and the two slide rods 12 are symmetrically arranged on the rotating frame 5 to make the rotating frame 5 more stable when moving up and down along the height direction.

[0025] The heating device 3 described above is equipped with an oil temperature regulating switch.

[0026] The inner cavity of the oil tank 2 is 380mm long, 320mm wide, and 180mm deep. It is suitable for use with more impellers 6 that are wetted with oil.

[0027] The rising and falling speeds of the aforementioned lifting screw are both set to 0.03 m / s.

[0028] The number of rotations of the aforementioned rotating motor is set to 2 to 3 revolutions.

[0029] The temperature of the heating device 3 is set to 180±0.5℃.

[0030] The bracket 1 is equipped with a power switch, a start switch and a stop switch for controlling the heating device 3, the lifting screw, the rotating motor, the position sensor 7 and the weight sensor 8.

[0031] The bracket 1 is equipped with a forward and reverse control switch for the aforementioned rotating motor, and a speed adjustment switch.

[0032] The bracket 1 is equipped with an operation screen 9, which is used to manually set the height and speed of the first descent of the lifting screw, the height and speed of the second descent of the lifting screw, the oil-coating time of the lifting screw, the start and stop positions of the range hood impeller 6, and to display the oil-coating time and number of runs of the second descent of the lifting screw.

[0033] The oil tank 2 mentioned above is equipped with an oil outlet valve.

[0034] The oil outlet valve is located on the front of the oil tank 2 and can be controlled manually or electrically, with the output end of the oil outlet valve facing downwards. The operation panel 9, power switch, start switch, stop switch, forward and reverse control switch for the rotating motor, and speed adjustment switch are integrated into one unit.

[0035] The impeller 6 can be detachably mounted on the rotating frame 5 using bolts, and is driven to rotate by the rotating shaft of the rotating motor. The hole at the center of the impeller 6 and the motor shaft are on the same axis, causing the impeller 6 to move around its own circumference. After pressing the power switch, the heating device 3 heats the oil tank 2 to above 180℃, melting the oil. The operating panel 9 allows switching between automatic and manual modes, or direct manual settings, to lower the lifting screw into the oil tank 2 in one or two descents, adjusting the speed and height of each descent. When lowering in two descents or automatically, the first descent can be set to a fast descent and the second slow descent, facilitating adjustment of the actual descent position. The first fast descent can be set by default to a 300mm descent at 0.05m / s, and the second descent to a 300mm descent at 0.02m / s. The height of the first and second descents can be accurately adjusted by identifying the heights using the position sensor 7. In use, lower the impeller 6 until its outer circumference is completely immersed in the oil in the oil tank 2. Rotate the motor 2-3 times in the set direction to evenly coat the impeller with oil. After stopping rotation, raise the lowering frame to leave the oil tank 2. Repeat the process of immersing the impeller 6 in the oil tank 2 2-3 times in the set automatic or manual rotation direction.

[0036] The weight sensor 8 detects changes in the weight of the impeller 6 to determine if the required oil immersion weight has been met, and the system stops manually or automatically once the requirement is met. Optionally, the lifting screw rises 200mm at a default speed of 0.02mm / s, with a return speed range of 0-60mm / s. Optionally, the position sensor 7 accurately detects the return stroke of the lifting screw and adjusts it accordingly. Then, the rotating motor is manually or automatically controlled to rotate at 15r / min for 5 minutes before stopping, thus further ensuring even oil application. Optionally, after the position sensor 7 detects the return stroke of the impeller 6, the lifting screw quickly returns to its initial position at a speed of 0.05m / s, with a stroke of 400mm, and then the impeller 6 is removed for drying. Both forward and reverse rotation can be selected according to operational requirements.

[0037] Optionally, the weight sensor 8 and position sensor 7 can be displayed on a screen or remote server for easy manual operation. They can also communicate with the controller to control the rotating motor and the lowering frame. Optionally, when set to a single descent, the descent speed can be manually adjusted using the acceleration and deceleration buttons on the operation screen 9. The heating device 3 and oil tank 2 can be integrated into one unit, with the heating device 3 employing an intelligent constant-temperature heating system.

[0038] The impeller 6 used in this embodiment is made of cold-plate electrophoresis material, mainly cylindrical in shape, with a diameter of 230-330 mm. The oil tank 2 maintains a temperature of 55±5℃ when not in use to keep the mixed oils such as lard and tallow in a liquid state. The dimensions of the oil tank 2 are not less than 380 mm long * 320 mm wide * 180 mm deep (ensuring that the rotating motor and rotating frame 5 do not interfere with the oil tank 2 and the oil surface). The thickness of the rotating frame 5 is <10 mm, and the vertical stroke is not less than 250 mm, meaning that when the lifting screw reaches its highest point, the bottom of the impeller 6 is not less than 50 mm from the upper surface of the oil tank 2 (the bottom of the impeller 6 is not less than 200 mm from the bottom of the oil tank 2). The bracket 1 is movable, for example, with casters installed.

[0039] In summary, this application provides a range hood impeller oil-drying device: the impeller 6 is detachably mounted on the rotating frame 5, allowing for cleaning of the impeller 6 after oiling; the rotating frame 5 is rotatably mounted on a lifting screw to drive the impeller 6 to rotate around its own center; and the oil tank 2 is used to hold oil and is open at the top; the lifting screw is slidably connected to the bracket 1 along the height direction and is located above the oil tank 2; after the heating device 3 heats the oil in the oil tank 2, the lifting screw is moved up and down to partially immerse the impeller 6 in the oil tank 2 for even oiling; the rotating frame 5 is equipped with a weight sensor 8 for sensing the weight of the range hood impeller 6 to obtain the required oiling weight, satisfying the testing of the cleaning effect of the impeller 6; the bracket 1 is equipped with a position sensor 7 for sensing the height of the lifting screw, facilitating the adjustment of the appropriate height of the impeller 6 during oiling. This utility model can solve the problems of high difficulty in manually oiling the impeller 6, inaccurate oil weight, and low uniformity.
