Description

[Technical field]

[0001] The present application relates to the field of range hoods. [Background technology]

[0002] In Asia, due to the traditional cooking habit of stir-frying, the oil content in the smoke produced during cooking is particularly high. Therefore, the range hood used to extract the oil smoke produced during cooking has become an important household appliance that is indispensable for daily home use. As people's requirements for quality of life continue to increase, range hoods are also constantly upgraded and improved. At present, there are many range hoods with smoke guide plates. However, the existing range hoods with smoke guide plates need to be further upgraded and improved. For example, when cleaning some range hoods, the smoke guide plate must be removed first, which brings inconvenience to the user. For another example, when cleaning some range hoods, the smoke guide plate must be moved to the cleaning position to form a cleaning opening. The cleaning opening is located below the smoke guide plate. The user must bend over and face upward to perform the cleaning operation, which results in a poor user experience.

[Specific implementation method]

[0032] In order to make the purpose, scheme and beneficial effects of the present application more clear, the present application is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0033] The present application provides a range hood embodiment, comprising a housing 1, a smoke collecting hood 2, a smoke guide plate 5 disposed on the smoke collecting hood 2, and an oil cup 4 with an opening facing upwards, such as Figure 1 and 3 As shown. The range hood is a side suction range hood. The housing 1, the fume hood 2 and the oil cup 4 are arranged in sequence from top to bottom. A fan is arranged in the housing 1, which is suitable for generating negative pressure to exhaust oil smoke. The oil cup 4 is in the shape of a long strip groove. The oil cup 4 is hung on the bottom wall of the fume hood 2. The bottom wall of the fume hood 2 is provided with an oil leakage hole, through which the grease attached to the fume hood 2 passes and drips into the oil cup 4. The housing 1 is hung on the wall. The housing 1 and the fume hood 2 are both close to the wall, and the housing 1 and the fume hood 2 are both fixed.

[0034] The smoke collecting hood 2 is provided with an inner cavity 14 and an air inlet suitable for conveying airflow to the inner cavity 14. Figures 1 to 4 As shown. The smoke hood 2 is also provided with an exhaust port, which is connected to the air flow channel in the housing 1. When the range hood extracts and exhausts oil smoke, the fan runs, generates negative pressure, forms an air flow, and the air flow flows through the air inlet and flows into the inner cavity 14, then passes through the exhaust port and flows into the air flow channel in the housing 1, flows through the fan, and then is discharged into the public flue. The air inlet is provided with a filter 3, as shown. Figure 3 shown.

[0035] The smoke guide plate 5 is provided with a first hinge 6, and the smoke collecting hood 2 is provided with a second hinge 7. Figure 3 The first hinge 6 and the second hinge 7 cooperate to make the smoke guide plate 5 hinged to the smoke collecting hood 2. In other words, the first hinge 6 and the second hinge 7 are hinged, the first hinge 6 is suitable for rotating relative to the second hinge 7, and the smoke guide plate 5 rotates relative to the second hinge 7 along with the first hinge 6. Specifically, the smoke guide plate 5 is configured to rotate around the second hinge 7 and switch between the first position and the second position.

[0036] When the smoke guide plate 5 is in the first position, the smoke guide plate 5 blocks the air inlet in the horizontal direction, and the edge of the smoke guide plate 5 is spaced apart from the smoke collecting hood 2 to form an air inlet gap 12 suitable for conveying airflow to the air inlet. Figure 1 and 2The air intake slit 12 is n-shaped, and the n-shaped opening of the air intake slit 12 faces backward and downward, as shown in FIG. Figure 1 When the smoke guide plate 5 is in the first position, the smoke guide plate 5 is tilted downward from the front to the back, the free end of the smoke guide plate 5 is located at the top of the smoke guide plate 5, and the first hinge 6 is located at the bottom of the smoke guide plate 5. When the smoke guide plate 5 switches from the first position to the second position, the free end of the smoke guide plate 5 rotates downward in a direction away from the smoke collecting hood 2 until a clean opening is formed. In other words, when the smoke guide plate 5 is in the second position, the smoke guide plate 5 is opened to form a clean opening, and the clean opening is located above the smoke guide plate 5, as shown in FIG. Figure 3 and 4 Through the cleaning opening, the user can conveniently clean the air inlet; specifically, through the cleaning opening, the user can conveniently remove the grease attached to the filter 3.

[0037] The smoke collecting hood 2 is provided with a smoke collecting cavity 13. When the smoke guide plate 5 is located at the first position, the smoke guide plate 5 is located at the open portion of the smoke collecting cavity 13, and the edge of the smoke guide plate 5 is spaced from the smoke collecting cavity 13 to form an air inlet gap 12. Figure 1 and 2 The smoke collecting cavity 13 is configured to guide the airflow flowing in from the air inlet slit 12 to the air inlet, and guide the airflow to flow through the filter screen 3 at the air inlet and flow into the inner cavity 14. When the smoke guide plate 5 is in the first position, the smoke guide plate 5 is spaced a certain distance from the filter screen 3 located at the rear side thereof, forming an oil smoke channel, as shown in FIG. Figure 2 When the smoke guide plate 5 is in the first position, if the fan is running, negative pressure is generated to form an airflow, which passes through the air inlet slit 12 and enters the oil smoke channel. Then, under the guidance of the smoke collecting cavity 13, the airflow flows through the filter screen 3 at the air inlet, flows into the inner cavity 14, then flows into the casing 1, and then is discharged into the public flue.

[0038] The first hinge 6 is provided with abutting portion 8. The second hinge 7 is provided with a stopper 9. Under the gravity of the smoke guide plate 5, the abutting portion 8 abuts against the stopper 9, so that the smoke guide plate 5 is maintained in the second position. Figure 3 and 4 When the smoke guide plate 5 is in the second position, the bottom edge of the smoke guide plate 5 is spaced a certain distance from the smoke collecting hood 2. The stopper 9 is covered with a plastic buffer for the abutment 8 to abut. Specifically, the plastic buffer is a plastic shell suitable for being fitted on the stopper 9.

[0039] When the smoke guide plate 5 is in the second position, the free end of the smoke guide plate 5 is higher than the bottom edge of the smoke guide plate 5. Figure 3 and 4As shown. When the smoke guide plate 5 is in the second position, the air inlet is partially exposed in the horizontal direction. In other words, when the smoke guide plate 5 is in the second position, the user can see a part of the air inlet when looking at the air inlet from front to back in the horizontal direction. Since the air inlet is provided with a filter 3, when the smoke guide plate 5 is in the second position, the user can see the filter 3 blocking the air inlet when looking at the air inlet from front to back in the horizontal direction.

[0040] When the smoke guide plate 5 is in the second position, the angle between the outer surface of the smoke guide plate 5 and the horizontal plane is less than 5°. Figure 3 and 4 As shown, on the one hand, the cleaning opening is large, which is convenient for cleaning operation; on the other hand, at this time, the free end of the smoke guide plate 5 is still higher than the bottom edge of the smoke guide plate 5, which facilitates the grease attached to the smoke guide plate 5 to gather toward the oil cup 4.

[0041] When the smoke guide plate 5 is in the first position, the free end of the smoke guide plate 5 is fixed to the smoke collecting hood 2. When the smoke guide plate 5 switches from the first position to the second position, the free end of the smoke guide plate 5 is separated from the smoke collecting hood 2. Specifically, when the smoke guide plate 5 is in the first position, the free end of the smoke guide plate 5 is magnetically adsorbed and fixed to the smoke collecting hood 2. Figure 1 and 2 The filter screen 3 is provided with two permanent magnets 10, and the inner surface of the smoke guide plate 5 is provided with two adsorbents 11, as shown in FIG. Figures 2 to 4 As shown, the two permanent magnets 10 correspond to the two adsorbing members 11. The adsorbing members 11 are configured to be magnetically adsorbed by the corresponding permanent magnets 10. When the smoke guide plate 5 is in the first position, the adsorbing members 11 are magnetically adsorbed by the corresponding permanent magnets 10. Figure 2 As shown, the free end of the smoke guide plate 5 is magnetically adsorbed and fixed to the smoke hood 2, so that the smoke guide plate 5 is maintained in the first position. When the smoke guide plate 5 is in the first position, the user applies a certain external force to the free end of the smoke guide plate 5 to make the adsorption member 11 detach from the corresponding permanent magnet 10 and switch the smoke guide plate 5 to the second position. When the smoke guide plate 5 is in the second position, the user applies a certain reverse external force to the free end of the smoke guide plate 5 to make the smoke guide plate 5 switch to the first position, so that the adsorption member 11 is magnetically adsorbed by the corresponding permanent magnet 10. At this time, the external force is removed and the smoke guide plate 5 is maintained in the first position.

[0042] When the smoke guide plate 5 is in the first position, the front wall of the oil cup 4 blocks the bottom edge of the smoke guide plate 5 in the horizontal direction. Figure 2In other words, when the smoke guide plate 5 is in the first position, the user cannot see the bottom edge of the smoke guide plate 5 when looking at the smoke guide plate 5 from the front to the back in the horizontal direction, because the front wall of the oil cup 4 blocks the bottom edge of the smoke guide plate 5 in the horizontal direction. When the smoke guide plate 5 switches from the first position to the second position, the bottom edge of the smoke guide plate 5 is always located above the opening of the oil cup 4. In other words, when the smoke guide plate 5 is in the first position, the bottom edge of the smoke guide plate 5 is located above the opening of the oil cup 4, as shown in FIG. Figure 1 and 2 When the smoke guide plate 5 is in the second position, the bottom edge of the smoke guide plate 5 is also located above the opening of the oil cup 4, as shown Figure 3 and 4 When the smoke guide plate 5 is in any position during the switching process from the first position to the second position, the bottom edge of the smoke guide plate 5 is also located above the opening of the oil cup 4. Thus, it is convenient for the oil cup 4 to collect the grease attached to the smoke guide plate 5.

[0043] The first hinge 6 and the second hinge 7 are provided with a rotating shaft on one side and a shaft hole for inserting the rotating shaft on the other side. When the smoke guide plate 5 switches between the first position and the second position, the rotating shaft rotates relative to the shaft hole. There are two first hinges 6 and two second hinges 7. The two first hinges 6 correspond to the two second hinges 7 one by one. One of the first hinges 6 cooperates with the corresponding second hinge 7 and is located on the left side of the range hood. The other first hinge 6 cooperates with the corresponding second hinge 7 and is located on the right side of the range hood. Figure 3 shown.

[0044] The smoke guide plate 5 includes a non-porous glass plate. When the smoke guide plate 5 is in the first position, only the non-porous glass plate of the smoke guide plate 5 is exposed and visible. Figure 1 The first hinge 6 is fixed to the inner surface of the non-porous glass plate, and the adsorption member 11 is also fixed to the inner surface of the non-porous glass plate. The second hinge 7 is arranged on the filter screen 3.

[0045] The components of different embodiments may be combined with each other in any feasible manner to achieve the purpose of this application.

[0046] The above are only optional embodiments of some implementation scenarios of the present application. It should be noted that, for ordinary technicians in this technical field, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the technical concept of the present application also fall within the protection scope of the present application.
