As we all know, the cleaning process of the range hood is very complicated, and it is very difficult to clean some stubborn oil stains. Due to the complicated process of cleaning the range hood, we do not clean the range hood frequently in daily life, which makes the cleaning process of the range hood more difficult. In order to solve this problem, we propose a household range hood with automatic cleaning function.
[0003] After searching, the Chinese patent application No. 201620225350.2 discloses a household range hood with an automatic cleaning function, including a range hood housing, a cleaning solution tank at the lower edge of the oil smoke suction area, a cleaning solution inlet pipe connected to the side of the cleaning solution tank, an automatic cleaning device symmetrically arranged on the inner wall of the dustproof housing, the automatic cleaning device electrically connected to the operation panel, and the automatic cleaning device is located at the lower side of the cleaning solution tank, an edge limit frame is installed at the bottom of the dustproof housing, a splash guard is clamped on the edge limit frame, and a sewage discharge pipe is connected to the bottom of the splash guard. The household range hood with an automatic cleaning function in the above document has the following shortcomings: oil stains will adhere to the cleaning parts after long-term use, and the cleaning parts cannot be cleaned. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a range hood with a cleaning and drainage function.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A range hood with a cleaning and drainage function comprises a chassis, an oil collecting box is arranged at the lower end of the chassis, an air intake grille is installed on the lower side wall of the chassis, a baffle is arranged inside the chassis parallel to the air intake grille, an exhaust pipe is installed at the upper end of the chassis, a motor is installed inside the exhaust pipe through a bracket, a fan blade is rotatably installed on the bracket, an output shaft of the motor is connected to the fan blade, and an operation panel is installed on the upper side wall of the chassis, and the operation panel is electrically connected to the motor.
[0007] As a further solution of the utility model: a filter plate is installed inside the chassis at the rear of the baffle.
[0008] As a further solution of the utility model: a telescopic cylinder is installed at the upper end of the chassis, and a rubber pad is installed at the output end of the telescopic cylinder. The rubber pad is a fluororubber that is oil-resistant, high-temperature-resistant, friction-resistant and has good elasticity. The telescopic cylinder is electrically connected to the operation panel.
[0009] As a further solution of the utility model: the rubber pad and the output end of the telescopic cylinder are connected via a connecting seat and a connecting plate, and the connecting plate is slidably installed in the connecting seat.
[0010] As a further solution of the utility model: a plurality of first fixing buckles are installed on both sides of the chassis, a side panel is installed on the side of the oil collecting box through a second fixing buckle, and a sealing gasket is installed between the side panel and the oil collecting box.
[0011] As a further solution of the utility model: the inner corners of the oil collecting box are all provided with rounded corners.

[0013] As a further solution of the utility model: the side wall of the chassis is provided with an observation window.
[0014] The beneficial effects of the utility model are:
[0015] Through the scheme, the operator can control the operation of the motor through the operation panel to perform negative pressure extraction. The sucked oil smoke will follow a "U"-shaped trajectory downward along the baffle and then enter the exhaust pipe from the rear. The oil particles in the oil smoke will collide and be adsorbed on the baffle due to inertia, and finally fall into the oil collecting box, reducing the oil smoke from adhering to the mechanism behind the device.
[0016] By installing the filter plate, the oil in the oil smoke can be further filtered to reduce the oil adhesion to the fan.
[0017] Through the solution, the telescopic cylinder will drive the rubber pad to push the oil stains attached to the baffle downward to the oil collecting box, making it convenient for the operator to clean it.
[0018] According to the solution, the operator can easily replace the rubber pad through the connecting plate and the connecting seat.
[0019] Through the scheme, the sealing gasket ensures that the connection is stable and there will be no oil leakage. The first fixing buckle and the second fixing buckle are convenient for the operator to remove the oil box and the side panel for cleaning. When removing the side panel, the operator flushes the oil box to facilitate the direct outflow of sewage and avoid flipping the oil collecting box back and forth, which causes inefficiency.
[0020] By setting the rounded corners, it is easier for the operator to clean and avoid the accumulation of oil stains at the 90-degree corners, which is difficult to clean.
[0021] By setting the lighting, the operator can use the equipment conveniently even in an environment with insufficient light.
[0022] By setting up the observation window, the operator can easily observe the status of the rubber pad and replace it in time. BRIEF DESCRIPTION OF THE DRAWINGS

Example 1
[0030] A range hood with a cleaning and drainage function, such as Figure 1-4As shown, it includes a chassis 1. In order to facilitate the cleaning of the range hood, an oil collecting box 2 is arranged at the lower end of the chassis 1, an air intake grille 3 is installed on the lower side wall of the chassis, a baffle 12 is arranged inside the chassis 1 parallel to the air intake grille 3, an exhaust pipe 6 is installed on the upper end of the chassis 1, a motor 7 is installed inside the exhaust pipe 6 through a bracket 8, a fan blade 9 is rotatably installed on the bracket 8, the output shaft of the motor 7 is connected to the fan blade 9, and an operation panel 5 is installed on the upper side wall of the chassis 1, and the operation panel 5 and the motor 7 are electrically connected.
[0031] Through the scheme, the operator can control the operation of the motor through the operation panel to perform negative pressure extraction. The sucked oil smoke will follow a "U"-shaped trajectory downward along the baffle and then enter the exhaust pipe from the rear. The oil particles in the oil smoke will collide and be adsorbed on the baffle due to inertia, and finally fall into the oil collecting box, reducing the oil smoke from adhering to the mechanism behind the device.
[0032] The device is further configured such that a filter plate 11 is installed at the rear of the baffle 12 inside the chassis 1 .
[0033] By installing the filter plate, the oil in the oil smoke can be further filtered to reduce the oil adhesion to the fan.
[0034] The device is further configured such that a telescopic cylinder 10 is installed at the upper end of the chassis 1, and a rubber pad 15 is installed at the output end of the telescopic cylinder 10. The rubber pad 15 is a fluororubber that is oil-resistant, high-temperature-resistant, friction-resistant and has good elasticity. The telescopic cylinder 10 is electrically connected to the operation panel 5.
[0035] Through the solution, the telescopic cylinder will drive the rubber pad to push the oil stains attached to the baffle downward to the oil collecting box, making it convenient for the operator to clean it.
[0036] The device is further configured such that the rubber pad 15 and the output end of the telescopic cylinder 10 are connected via a connecting seat 13 and a connecting plate 14 , and the connecting plate is slidably installed in the connecting seat 13 .
[0037] According to the solution, the operator can easily replace the rubber pad through the connecting plate and the connecting seat.
[0038] The device is further configured such that a plurality of first fixing buckles 17 are installed on both sides of the chassis 1 , a side plate 19 is installed on the side of the oil collecting box 2 via a second fixing buckle 18 , and a sealing gasket 20 is installed between the side plate 19 and the oil collecting box 2 .
[0039] Through the scheme, the sealing gasket ensures that the connection is stable and there will be no oil leakage. The first fixing buckle and the second fixing buckle are convenient for the operator to remove the oil box and the side panel for cleaning. When removing the side panel, the operator flushes the oil box to facilitate the direct outflow of sewage and avoid flipping the oil collecting box back and forth, which causes inefficiency.
[0040] The device is further configured such that the inner corners of the oil collecting box 2 are all provided with rounded corners.
[0041] By setting the rounded corners, it is easier for the operator to clean and avoid the accumulation of oil stains at the 90-degree corners, which is difficult to clean.
[0042] The device is further configured such that a lighting lamp 4 is installed above the chassis 1 , and the lighting lamp 4 is electrically connected to the operation panel 5 .
[0043] By setting the lighting, the operator can use the equipment conveniently even in an environment with insufficient light.
[0044] The device is further configured such that a side wall of the chassis 1 is provided with an observation window 16 .
[0045] By setting up the observation window, the operator can easily observe the status of the rubber pad and replace it in time.
[0046] Working principle: When the range hood is working, the telescopic cylinder 10 is in a retracted state. At this time, the motor 7 drives the fan blades 9 to perform negative pressure adsorption. The inhaled oil smoke will follow a "U"-shaped trajectory downward along the baffle 12 and then pass through the filter plate 11 to enter the exhaust pipe 6 from the rear. The oil particles in the oil smoke will collide and be adsorbed on the baffle 12 due to inertia, and finally fall into the oil collecting box 2 below, reducing the attachment of oil smoke to the mechanism behind the device; after the range hood is finished working, the motor 7 stops working, and the telescopic cylinder 10 starts working at this time. The telescopic cylinder 10 pushes the rubber pad 15 to move downward, pushing the oil stains attached to the baffle 12 to the lower end and falling into the oil collecting box 2; when a certain amount of oil stains accumulate in the oil collecting box 2, the operator can remove the oil collecting box 2 for cleaning through the first fixing buckle 17.
[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
