Description

Technical Field

[0001] This utility model relates to a range hood. Background Technology

[0002] The existing technology, Chinese patent 201720320618.5, describes a non-stick range hood, including an oil fume collection chamber, an oil filter, an air duct, a main control board, a front glass panel, an air handling unit, and a fan installed inside the air handling unit. The top plate of the oil fume collection chamber is flat and is fixedly connected to and communicates with the lower end of the air duct. The top of the air duct is fixedly connected to and communicates with the air handling unit. The front glass panel covers the front surface of the air handling unit. Baffles are provided on both sides of the top plate of the oil fume collection chamber in the left and right directions. The rear wall of the air duct is flat, and the front wall is curved. The area of ​​the air duct gradually decreases from bottom to top. The problem is that when the fan is working, a negative pressure is generated in the oil fume collection chamber. Under the action of the negative pressure, the oil-absorbing pads on the bottom plate of the oil fume collection chamber move and block the air inlet of the air duct. Utility Model Content

The air handling unit, flue, and casing are arranged and connected. The flue is connected to the mounting hole, and the air inlet of the flue is covered by a protective net. The oil screen and the smoke collection port are matched.

[0005] The special feature of the range hood with a protective net is that the smoke inlet end of the flue is provided with an interface; The protective net is equipped with fixed brackets at both ends; The interface is inserted into the housing through the mounting holes, and the mounting bracket is fixed to the two end plates of the interface.

[0006] The special feature of the range hood with a protective net is that the lower end of the rear wall panel of the interface has a notch.

[0007] The special feature of the range hood with a protective net is that the protective net has an upward angle from back to front.

[0008] The special feature of the range hood with a protective net is that the lower end of the front wall panel of the interface is angular. The protective netting is angular.

[0009] The range hood with a protective net is characterized in that: the lower end of the front wall panel of the interface is angular, the lower end of the front wall panel of the interface is provided with a front oil guide groove, and the side wall panel is provided with a side oil guide groove, the two ends of the front oil guide groove are connected to the front end of the side oil guide groove.

[0010] The special feature of the range hood with a protective net is that the side wall panel and back panel of the flue are integrally formed with the side wall panel and back panel of the air handling unit. The front wall panel of the flue and the bottom plate of the air handling unit are integrally formed and are curved, and the front end face of the side wall panel of the flue is also curved.

[0011] This utility model discloses a range hood with a protective net. The protective net prevents the oil-absorbing pad or paper located on the bottom plate of the oil storage chamber from moving upward and entering the air handling unit, and also prevents blockage of the air inlet of the flue.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figure 1 , Figure 2 As shown, a range hood with a protective net includes a casing 1, an oil filter 2, a flue 3, an air handling unit 4, and a protective net 5. The housing 1 includes a top horizontal part 11, a mounting hole 12 on the top, a bottom smoke collection chamber 13 and a smoke collection port (not marked), and the bottom smoke collection chamber 13 below the smoke collection port serves as an oil reservoir; the front surface of the bottom smoke collection chamber 13 has an acute angle α with the front horizontal plane; The air handling unit 4, flue 3, and casing are installed together and connected. Flue 3 is connected to mounting hole 12, and protective net 5 covers the air inlet of flue 3. Oil screen 2 and smoke collection port are detachably connected. With this structure, when oil-absorbing paper or oil-absorbing pad is placed on the bottom plate of the bottom smoke collection chamber 13, when the fan in the air handling unit 4 is working, the oil fumes enter the casing through the oil screen; the oil fumes then enter the air handling unit 4 through the protective net 5 and flue 3; when the fan is working, it generates negative pressure, and when the oil-absorbing paper or oil-absorbing pad moves upward, the protective net prevents the oil-absorbing paper or oil-absorbing pad from entering the air handling unit and the fan; thus effectively protecting the fan.

[0021] As a further improvement of this utility model: the smoke inlet end of the flue 3 is provided with an interface 31; The protective net 5 is provided with fixed brackets 51 at both ends; The interface is inserted into the housing 1 through the mounting hole, and the fixing bracket 51 and the two end plates of the interface 31 are fixed with screws.

[0022] As a further improvement of this utility model: the lower end of the rear wall plate of the interface 31 is provided with a notch 32.

[0023] like Figure 5 As shown, the protective net 5 has a rising angle from back to front, with an angle of 5-10 degrees. This allows for rapid oil drainage from the protective net 5 and prevents oil from adhering to it. like Figure 5 As shown, it also includes a right-angled bracket 52, the protective net 5 is fixed to the hypotenuse of the right-angled bracket 52, and a fixed bracket 51 is provided on one right-angled side; the fixed bracket 51 is fixed to the two end plates of the interface 31 with screws.

[0024] As a further improvement of this utility model: the lower end of the front wall plate 311 of the interface 31 is angular; like Figure 2 As shown, the protective net 5 is angular, with an included angle β of 140-170.

[0025] like Figure 1 , Figure 3As shown, the lower end of the front wall panel of the interface 31 is angular. The lower end of the front wall panel of the interface 31 is provided with a front guide oil groove 311, and the side wall panel is provided with a side guide oil groove 312. The side guide oil groove 312 has a rear opening, and the two ends of the front guide oil groove 311 are connected to the front end of the side guide oil groove 312. With this structure, the oil on the front and side walls of the flue 3 enters the front guide oil groove 311 and the side guide oil groove 312, and is guided into the oil storage cup through the rear panel of the casing 1 at the notch 32; preventing oil dripping onto the oil filter 2. Because the front guide oil groove is angular, it flows rapidly from the middle to both sides and enters the side guide oil groove.

[0026] As a further improvement of this utility model: the side wall panel and back panel of the flue 3 are integrally formed with the side wall panel and back panel of the air handling unit 4. The front wall panel of flue 3 and the bottom plate of air handling unit 4 are integrally formed and are curved, and the front end face of the side wall panel of flue 3 is also curved. With this design, the flue gas flows smoothly and quickly.

[0027] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
