Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to a novel range hood. Background Art

[0002] A range hood, also known as an oil fume extractor, is a kitchen appliance for purifying the kitchen environment. It can quickly extract the waste generated by stove combustion and the harmful oil fumes produced during cooking outdoors, while condensing and collecting the oil fumes to reduce pollution, purify the air, and has the safety guarantee functions of preventing poisoning and explosion.

[0003] Currently, there is generally only one smoke outlet for the existing range hoods. The smoke outlet can be connected to the exhaust outlet in the kitchen through a pipeline for smoke exhaust. However, due to the exhaust outlets at different positions in the structures of different kitchens, if the smoke outlet of the range hood is located directly above and the exhaust outlet of the kitchen is located on the left and right sides, the pipeline used needs to be bent. The inner wall of the pipeline at the bent part is easily impacted by the smoke, resulting in pipeline rupture and shortening of the service life. Secondly, a longer pipeline needs to be used, which will increase the cost. Therefore, we propose a novel range hood. Summary of the Utility Model

A plurality of blades are fixedly connected between the first connecting plate and the second connecting plate. An air outlet connecting port is formed between adjacent blades. An air inlet connecting port is provided on the first connecting plate. The air inlet connecting port and the air outlet connecting port are communicated; an installation hole is provided on the second connecting plate. The rotating shaft end of the variable-frequency motor is fixedly installed at the installation hole.

If the exhaust port of the kitchen faces the balcony of another building directly across and the distance between the two is short, in order to avoid the flue gas affecting the use of the opposite house, the pipeline can be connected from the side of the air outlet housing 4 to exhaust the flue gas to an open space at the other end, thus ensuring its use effect.

[0027] As a preferred embodiment; the inner wall of the air outlet 8 is provided with an internal thread, and the air outlet 8 of the air outlet shell 4 is threadedly connected with a sealing cover 9; it can be understood that by providing an internal thread, it is easy to install and disassemble the sealing cover 9, so that it can be connected to the pipe to exhaust from different directions.

[0028] As a preferred embodiment, the air outlet 8 is a circular structure. The circular setting can better conform to the structural connection of the pipeline, making its connection more convenient. It only needs to set an external thread on the outer wall of the pipeline to thread the air outlet 8, which is easy to operate. In addition, the air outlet 8 can also be set to other shapes without limiting the air outlet 8.

[0029] As a preferred embodiment, an air inlet shell 10 is fixedly installed at the air inlet 5, and the diameter of the air inlet shell 10 decreases from the outside to the inside. It can be understood that by providing the air inlet shell 10, the air is continuously pressurized during the air intake process, further enhancing the air outlet pressure and achieving a better exhaust effect.

[0030] As a preferred embodiment, the driving device 2 adopts a variable frequency motor, and the rotating shaft end of the variable frequency motor is fixedly connected to the impeller mechanism 3.

[0031] As a preferred embodiment; the impeller mechanism 3 includes a first connecting plate 11 and a second connecting plate 12, a plurality of blades 13 are fixedly connected between the first connecting plate 11 and the second connecting plate 12, an air outlet connection port 14 is formed between adjacent blades 13, the air outlet connection port 14 is connected to the air outlet, an air inlet connection port 15 is provided on the first connecting plate 11, the air inlet connection port 15 is connected to the air inlet 5, and the air inlet connection port 15 and the air outlet connection port 14 are connected; a mounting hole 16 is provided on the second connecting plate 12, and the shaft end of the variable frequency motor is fixedly installed at the mounting hole 16; it can be understood that the plurality of blades 13 in the present application have a small spacing between the blades 13, in other words, the blades 13 are densely arranged, which can effectively reduce the noise of the range hood.

[0032] As a preferred embodiment, a plurality of reinforcing columns 17 are welded to the inner wall of the second connecting plate 12, and the other end of the reinforcing column 17 is welded to the blade 13 or to the first connecting plate 11; by providing the reinforcing column 17, the rotation of the impeller mechanism 3 is more stable and the wind output intensity is enhanced.

[0033] As a preferred embodiment, the number of the reinforcing columns 17 is three, and the three reinforcing columns 17 enclose a triangular structure; the triangular structure can further enhance the stability of the impeller mechanism 3.

[0034] As a preferred embodiment, screw holes are provided on the air outlet housing 4, and the air outlet housing 4 is detachably mounted on the housing 1 by screws; this facilitates the replacement of air outlet housings 4 of different specifications to meet the needs of different users. At the same time, it is convenient to disassemble the air outlet housing 4 for cleaning.

[0035] As a preferred embodiment, a first mounting seat 18 is welded to the outer side of the second connecting plate 12. First adjustment holes 19 are provided on both the left and right sides of the first mounting seat 18, and second adjustment holes 20 are provided at both ends of the top surface of the first mounting seat 18. Both the first adjustment holes 19 and the second adjustment holes 20 are in the structure of strip holes. The left and right sides of the first mounting seat 18 are mounted with a second mounting seat 21 through the first adjustment holes 19. A support leg 22 is vertically provided outward at the bottom of the second mounting seat 21.

Since when used in different environments, the bottom position of the housing 1 may be lower than the bottom position of the second mounting seat 21, at this time, the second mounting seat 21 can be adjusted to move upward so that the bottom surface of the second mounting seat 21 can contact the ground or the support surface, which can improve the stability of the motor during use. In addition, the setting of the second adjustment holes 20 enables the position of the variable-frequency motor to be adjusted back and forth to adapt to the use of motors of different models, and the general effect is better.

[0036] It should be noted that the main problems in the prior art are: since the exhaust ports in different kitchens are in different positions, if the smoke outlet of the range hood is directly above and the exhaust port of the kitchen is on the left and right sides, the pipeline used needs to be bent. Firstly, the inner wall of the pipeline at the bent part is easily continuously impacted by the flue gas, resulting in the pipeline rupture and thus shortening the service life. Secondly, a longer pipeline needs to be used, which will increase the cost.

[0037] Therefore, after the improvement of this application, by providing the air outlet housing 4 and a plurality of air outlet holes 8 with different directions are provided on the air outlet housing 4, no matter which side of the air outlet housing 4 the exhaust port of the kitchen is set on, the pipeline can be installed linearly to discharge the flue gas, without bending the pipeline, making the pipeline more durable and capable of shortening the use of the pipeline, further reducing the use cost.
