Description

TECHNICAL FIELD

[0001] The utility model relates to the field of range hood, especially to a range hood air bellow. BACKGROUND

[0002] The main functions of the household range hood include smoke exhaust and air purification, which can keep the air fresh by sucking away the oil smoke, peculiar smell and hot air generated during cooking, remove harmful substances in the oil smoke through the filter system, reduce indoor pollution, prevent the oil smoke from depositing on the wall and furniture, and facilitate cleaning.

[0003] The air bellow is the core component of the range hood, which is internally provided with a volute assembly, and the fan in the volute generates airflow to suck and discharge the oil smoke outside.

[0004] The existing air bellow is composed of multiple parts and is point-welded and spliced, which has poor sealing performance and is easy to leak oil stains, and the quality is difficult to guarantee due to manufacturing tolerances.

[0005] Therefore, the present inventors have made further research and developed a range hood air bellow, which is generated in the case. CONTENT OF THE UTILITY MODEL

[0006] The utility model aims at providing a range hood air bellow which can better remove accumulated oil while ensuring production quality.

[0007] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0008] A range hood air bellow, which comprises an integrally stretched body, a volute assembly is arranged in the body, an air outlet seat is arranged at the top of the body, an oil guide groove is arranged at one side of the air outlet seat and the middle of the top of the body, the oil guide groove is at a low position, and an oil leakage hole is arranged at one end of the oil guide groove.

[0009] The air bellow body is integrally stretched to reduce splicing welds, and the oil guide groove at the top is relatively low (i.e., the top panel is slightly inclined relative to the position of the oil guide groove), so that the accumulated oil is guided to the oil leakage hole for discharge, and the volute assembly, the range hood mesh plate, the smoke guide plate and other internal oil paths are finally guided to the oil cup.

[0010] Further, a maintenance hole is arranged on the front surface of the body, the maintenance hole is covered by a maintenance cover plate, and a decorative cover is further arranged outside the maintenance cover plate.

[0011] The volute assembly can be maintained without disassembling the range hood body through the maintenance hole, and the front surface refers to the side surface facing the user in the working state.

[0012] Further, the range hood body is arranged at the bottom of the body.

[0013] Further, an air bellow hanging plate is arranged at the back surface of the body.

[0014] The bellows body is installed through the bellows hanging plate.

[0015] Further, the oil leakage holes are vertically distributed relative to the oil guide groove.

[0016] The shape of the oil leakage holes refers to the structure of a single louver blade.

[0017] After the above scheme is adopted, the utility model has the following advantages compared with the prior art:

[0018] The integrated stretching has no welding seam and no sharp angle, is easy to clean, has good sealing performance and no risk of oil leakage; the overall stretching of the mold ensures consistency during batch manufacturing; the top has louver-type oil leakage holes and a middle sunken oil guide groove, which can ensure that accumulated oil does not flow everywhere and affect the work of other elements.

[0025] Air inlet seat 3, range hood body 4, bellows hanging plate 5, volute assembly 6. DETAILED DESCRIPTION

[0026] The utility model will be further described below in combination with the drawings and specific embodiments.

[0027] As Figure 1 shown, a range hood bellows is arranged above the range hood body 4, which mainly includes a vertically-through cubic body, and the body is mainly integrally stretched through a mold, so that there is no welding seam or joint seam between the sides.

[0028] As Figure 2 shown, the upper body 1 is provided with an air outlet seat 3, the bottom of the air outlet seat 3 is of a rectangular structure, and the top is of a circular structure, which is used for connecting with a ventilation pipeline. On the side of the body 1 of the air outlet seat 3, an oil guide groove 11 is arranged, the oil guide groove 11 transversely crosses the top of the body 1, and the position of the oil guide groove 11 is relatively low, that is, the accumulated oil around can be guided into the oil guide groove 11.

[0029] As Figure 3As shown, one end of the oil guide groove 11 is provided with an oil leakage hole 12, the oil leakage hole 12 is short and perpendicular to the oil guide groove 11, and an arc blade structure is arranged below the oil leakage hole 12 for guiding the accumulated oil.

[0030] The front side of the body 1, i.e. the side facing the user, is provided with a maintenance hole 13, the area of the maintenance hole 13 is slightly smaller than the front side of the body 1, and the maintenance hole 13 is covered by the maintenance cover plate 2, and the maintenance cover plate 2 is covered by the decorative cover 21. When the volute assembly 6 inside the body 1 needs to be maintained, the decorative cover 21 and the maintenance cover plate 2 can be disassembled to see the volute assembly 6 inside the body 1.

[0031] The back side of the body 1 is provided with a wind box hanging plate 5, and the wind box can be arranged at a place such as a wall through the wind box hanging plate 5.

[0032] The above is only a specific embodiment of the present application, and all the words such as "up, down, left, right, middle" involved in the present application are only for reference, not absolute limitation, and any non-substantial change made by using the present application shall belong to the behavior of infringing the protection scope of the present application.
