Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a detachable and assembled oil filter structure for a high-suction seven-character range hood. Background Technology

[0002] Range hoods, appliances that quickly remove and exhaust harmful fumes from stove combustion and cooking processes outdoors, have become indispensable household kitchen appliances. After a period of use, the suction and exhaust system of a range hood accumulates a lot of grease, making it difficult to clean and affecting its smoke extraction and exhaust efficiency. Therefore, it is necessary to install an grease filter at the air inlet to improve grease separation. This effectively reduces grease buildup on the internal suction and exhaust system, thus solving the problems of difficult cleaning and impaired smoke extraction.

[0003] Most range hoods nowadays smoke from the top and have an oil filter at the top. However, this single oil filter can cause excessive grease to accumulate on the top of the range hood, requiring frequent disassembly and cleaning. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a detachable and removable oil filter structure for a high-suction seven-character range hood.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A detachable oil filter structure for a high-suction seven-character range hood includes an outer shell assembly. The outer shell assembly has an internal cavity. Limiting plates are symmetrically arranged on both side walls of the inner cavity of the outer shell assembly. A second oil filter assembly is installed in the inner cavity of the outer shell assembly at the limiting plates on both sides. A first oil filter assembly is arranged above the second oil filter assembly on the outer shell assembly. A limiting baffle is horizontally installed on the outer surface of the outer shell assembly below the first oil filter assembly.

[0007] In addition, a preferred structure is that the outer shell assembly has symmetrically formed limit baffle mounting grooves on both sides of the limit baffle, and the limit baffle is installed in the limit baffle mounting groove.

[0008] Furthermore, in a preferred configuration, slots are symmetrically provided on both sidewalls of the housing assembly at the mounting groove of the limiting baffle.

[0009] In addition, a preferred structure is that limit pins are symmetrically fixedly connected to one side surface of the limit baffle near the two side edges, and the limit pins are inserted into the slots.

[0010] Furthermore, in a preferred configuration, the limiting baffle abuts against one side of the first oil filter assembly.

[0011] Furthermore, in a preferred configuration, an oil guide plate is inclinedly disposed within the inner cavity of the outer casing assembly below the first oil filter assembly.

[0012] Furthermore, a preferred configuration is that the top of the housing assembly is provided with a duct cover.

[0013] Furthermore, in a preferred configuration, an oil collection box is provided at the bottom of the housing assembly and below the oil guide plate.

[0014] The beneficial effects of this utility model are as follows: By setting a first filter screen assembly and a second oil filter screen assembly, the outer shell assembly has two oil fume inlets, which can achieve dual smoke extraction from the top and side, resulting in greater suction power of the range hood, improved oil fume separation, and prevention of excessive grease adsorption on the first filter screen assembly at the top. In addition, the second oil filter screen assembly has a simple installation structure, is easy to disassemble, and is easy to replace and clean. Attached Figure Description

[0023] 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.

[0024] Reference Figure 1-7 A high-suction seven-character range hood oil filter assembly and disassembly structure includes an outer shell assembly 1. The outer shell assembly 1 has an internal cavity. Limiting plates 14 are symmetrically arranged on both sides of the inner cavity of the outer shell assembly 1. A second oil filter assembly 6 is installed in the inner cavity of the outer shell assembly 1 at the limiting plates 14 on both sides. A first oil filter assembly 5 is arranged above the second oil filter assembly 6 on the outer shell assembly 1. A limiting baffle 4 is horizontally installed on the outer surface of the outer shell assembly 6 below the first oil filter assembly 5. The limiting plates 14 are used to install the first oil filter assembly 5, and the limiting baffle 4 is used to block the air duct above the first oil filter assembly 5 while resisting the first oil filter assembly 5.

[0025] Furthermore, the outer casing assembly 1 has symmetrically opened limit baffle mounting grooves 12 on both sides of the limit baffle 14. The limit baffle 4 is installed in the limit baffle mounting groove 12, and the limit baffle mounting groove 12 is used to install the limit baffle 4.

[0026] In addition, slots 13 are symmetrically provided on both sides of the housing assembly 1 at the mounting groove 12 of the limiting baffle. Limiting pins 41 are symmetrically fixedly connected to one side surface of the limiting baffle 4 near the two sides. The limiting pins 41 are inserted into the slots 13 and are used to insert into the slots 13.

[0027] At the same time, the limiting baffle 4 abuts against one side of the first oil filter assembly 5.

[0028] Furthermore, an oil guide plate 11 is inclinedly provided in the inner cavity of the outer shell assembly 1 below the first oil filter screen assembly 5, which facilitates the guidance of the oil flowing down from the first oil filter screen assembly 5 to the lower part.

[0029] In addition, a duct cover 2 is provided on the top of the housing assembly 1.

[0030] An oil collection box 3 is provided at the bottom of the outer casing assembly 1 and below the oil guide plate 11. The oil collection box 3 is used to collect the oil flowing down from the oil guide plate 11.

[0031] In this embodiment, when disassembling the first oil filter assembly 5, it is only necessary to pull the limiting pin 41 out of the slot 13 and then remove the limiting baffle 4 from the limiting baffle mounting slot 12. The first filter assembly 5 can then be pulled out from the limiting pin 14 for quick replacement and cleaning. In conjunction with the second oil filter assembly 6, it can achieve double smoke extraction from the top and side.

[0032] In this utility model, by setting the first filter assembly 5 and the second oil filter assembly 6, the outer shell assembly 1 is equipped with two oil fume inlets, which can achieve dual smoke extraction from the top and side, resulting in greater suction power of the range hood, improved oil fume separation, and prevention of excessive grease adsorption on the first filter assembly 5 at the top. Furthermore, the second oil filter assembly 6 has a simple installation structure, is easy to disassemble, and is easy to replace and clean.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
