Description

Technical Field

[0001] The utility model relates to the field of range hoods, in particular to a range hood with an oil-proof lighting lamp. Background Art

[0002] As one of the core components of a range hood, how to prevent the condensation pollution, intrusion and penetration of oil fume during the use process has always troubled users and R & D personnel. The existing lighting lamp components are directly installed outside the range hood. After the range hood is used for a period of time, a large amount of oil stains will condense on the surface of the lighting lamp, which will not only seriously affect the lighting effect, but also because there are mating gaps and dead corners in the installation structure between the lamp and the range hood, and the gaps and dead corners are easy to hide dirt and are very troublesome to clean.

[0003] The patent document with the Chinese application number 201921511765.6 and the publication date of July 14, 2020 discloses an oil fume-proof lighting lamp and a range hood. The lighting lamp includes a panel with a smoke inlet and a lighting lamp. Among them, the panel is provided with a light-transmitting area. The lighting lamp component includes a light-emitting module, a lamp mounting plate and a protective lamp housing with an opening on one side. The light-emitting module is installed in the protective lamp housing. The lamp mounting plate is connected to the back of the panel and is provided with an opening for the light to pass through. The opening corresponds to the light-transmitting area. The protective lamp housing is connected to the lamp mounting plate and covers the opening.

[0004] However, the lighting lamp and the light-transmitting area are arranged close to the smoke inlet of the range hood, so that the oil fume will contact the light-transmitting area, causing pollution to the light-transmitting area, and further affecting the light-emitting effect of the lighting lamp. Content of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a range hood with an oil-proof lighting lamp. The air curtain airflow blown out by the air curtain intercepts the oil fume approaching the light-transmitting area. Under the action of the air curtain airflow, the intercepted oil fume moves closer to the air inlet again, improving the smoke exhaust effect on the oil fume and protecting the lighting lamp and the light-transmitting area from oil fume pollution.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] The range hood with an oil-proof lighting lamp described in the utility model includes a smoke collecting hood. There is an air inlet on one side of the smoke collecting hood, and a light-transmitting area is provided on the other side of the smoke collecting hood. The lighting lamp is arranged in the smoke collecting hood and corresponds to the light-transmitting area. The light emitted by the lighting lamp passes through the light-transmitting area and shoots outwards. An air curtain is arranged between the air inlet and the light-transmitting area. The air curtain is located below the light-transmitting area. The air inlet is located below the air curtain. The air outlet direction of the air curtain is inclined and approaches the light-transmitting area. The air curtain airflow blown out is used to intercept the oil fume approaching the light-transmitting area and drive the intercepted oil fume to flow towards the air inlet.

[0008] Preferably, a slow reflection layer is provided on the surface of the light-transmitting area, and the slow reflection layer is used to perform slow reflection on the light emitted by the lighting lamp.

[0009] Preferably, the slow reflection layer is screen-printed semi-transparent ink or a semi-transparent film.

[0010] Preferably, the slow reflection layer is formed by sandblasting treatment or pickling corrosion.

[0011] Preferably, the smoke collecting hood includes a panel and a hood body. The panel is arranged at the bottom of the hood body, the light-transmitting area is arranged on the panel, a bracket is arranged inside the panel, an installation groove is formed between the bracket and the panel, and the lighting lamp is arranged in the installation groove.

[0012] Preferably, a buckle is arranged on the bracket, the buckle protrudes towards the direction close to the light-transmitting area, and the buckle presses the lighting lamp tightly against the light-transmitting area.

[0013] Preferably, the lighting lamp includes a lamp housing and lamp beads. The lamp housing is provided with a slot, and the lamp beads are inserted into the lamp housing.

[0014] Preferably, the bracket is a bracket made of metal material, and the lamp housing is a lamp housing made of resin material; the lamp beads are in contact with the inner wall of the lamp housing, and the outer wall of the lamp housing is in contact with the bracket.

[0015] Compared with the prior art, the beneficial effects of the gearbox of the present invention are mainly reflected in: the lighting lamp is arranged inside the smoke collecting hood, and the smoke collecting hood protects the lighting lamp to avoid oil fume pollution of the lighting lamp, and the light-transmitting area realizes the outward emission of the light emitted by the lighting lamp; at the same time, an air curtain is arranged, the air curtain is located below the light-transmitting area, and the air curtain airflow blown by the air curtain intercepts the oil fume approaching the light-transmitting area to avoid oil fume pollution of the light-transmitting area, so that the light-emitting effect of the lighting lamp is not affected by oil stains; at the same time, the air inlet is located below the air curtain and the air outlet direction of the air curtain is inclined towards the light-transmitting area, so that the air curtain airflow will not interfere with the oil fume entering the air inlet; the oil fume close to the light-transmitting area flows downward under the action of the air curtain airflow, and then acts with the airflow entering the air inlet again, so that the oil fume approaches the air inlet again, improving the smoke exhaust effect on the oil fume. The air curtain can not only intercept the oil fume approaching the light-transmitting area, but also drive the intercepted oil fume to re-enter the air inlet and then be discharged through the range hood.

[0016] A slow reflection layer is arranged on the surface of the light-transmitting area to improve the diffuse reflection effect of the light-transmitting area, so that the light emitted by the light-transmitting area is evenly diffused.

[0017] The cooperation between the panel and the bracket is used to accommodate the lighting lamp. The length of the light-transmitting area is the same as the length of the panel, so as to increase the light-emitting area and improve the lighting effect; by arranging the buckle to press the lighting lamp tightly, the buckle provides a downward pre-tightening force on the lighting lamp, so that the lighting lamp is stably arranged on the light-transmitting area.

[0018] In the lighting lamp, the lamp beads are directly inserted and fixedly installed in the lamp housing, improving the installation efficiency; at the same time, the oil and dirt resistance performance of the lamp beads is further enhanced. The lamp housing shields the lamp beads, reducing the probability of the lamp beads being contacted by oil and dirt.

[0019] A bracket and a lamp housing made of metal are provided for dissipating heat from the lamp beads. The lamp beads are in contact with the lamp housing, and the lamp housing is in contact with the bracket. In this way, the heat of the lamp beads is transferred to the bracket through the outer shell, reducing the heat accumulation of the lamp beads. At the same time, the air curtain is arranged close to the lighting lamp, and the air curtain airflow blown by the air curtain can take away the heat in the smoke collecting hood, further reducing the temperature of the lamp beads.

[0020] The utility model intercepts the oil fume approaching the light-transmitting area by the air curtain airflow blown by the air curtain. Under the action of the air curtain airflow, the intercepted oil fume approaches the air inlet again, improving the oil fume exhaust effect and protecting the lighting lamp and the light-transmitting area from being polluted by oil fume.

[0038] This embodiment provides a range hood with an oil-proof lighting lamp, as Figure 1-8 shown, including a smoke collecting hood 1, an air inlet 2 on one side of the smoke collecting hood 1, a light transmission area 3 on the other side of the smoke collecting hood 1, a lighting lamp 4 is arranged in the smoke collecting hood 1 and corresponds to the light transmission area 3, and the light emitted by the lighting lamp 4 passes through the light transmission area 3 and shoots outwards; the lighting lamp 4 is arranged inside the smoke collecting hood 1, and the smoke collecting hood 1 protects the lighting lamp 4 to avoid oil fume pollution of the lighting lamp 4.

[0039] A wind curtain 5 is provided between the air inlet 2 and the light-transmitting area 3. The wind curtain 5 is located below the light-transmitting area 3, and the air inlet 2 is located below the wind curtain 5. The air outlet direction of the wind curtain 5 is inclined and approaches the light-transmitting area 3. The air flow blown out by the wind curtain 5 is used to intercept the lampblack approaching the light-transmitting area 3 and drive the intercepted lampblack to flow towards the air inlet 2. The wind curtain is a wind curtain machine, which is a prior art and will not be elaborated here. The horizontal height of the wind curtain 5 is located below the light-transmitting area 3. The air flow of the wind curtain 5 blown out intercepts the lampblack approaching the light-transmitting area 3, preventing the lampblack from polluting the light-transmitting area 3, so that the light-emitting effect of the lighting lamp 4 is not affected by the oil stain. At the same time, the air inlet 2 is located below the wind curtain 5 and the air outlet of the wind curtain 5 is inclined towards the light-transmitting area 3, so that the air flow of the wind curtain 5 will not interfere with the lampblack entering the air inlet 2. The lampblack close to the light-transmitting area 3 flows downward under the action of the air flow of the wind curtain 5, and then acts again with the air flow entering the air inlet 2, making the lampblack approach the air inlet 2 again, improving the exhaust effect of the lampblack. The wind curtain 5 can not only intercept the lampblack approaching the light-transmitting area 3, but also drive the intercepted lampblack to re-enter the air inlet 2 and then be discharged through the range hood.
