Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a panel assembly for a range hood and a range hood. BACKGROUND

[0002] The existing range hood relies on the operation of an internal fan system to form a negative pressure area, and the oil fume flow in the kitchen is discharged outdoors after passing through the range hood under the action of atmospheric pressure. In order to avoid oil fume escape, a movable smoke baffle is generally arranged at the smoke inlet of the range hood, and the specific example is a Chinese patent application with the application number 202310804283.4 and the application publication number CN116734301A, namely, a smoke baffle driving system, a smoke baffle driving method, a range hood, and a storage medium, the smoke baffle driving system is connected with the smoke baffle and includes a motor, a transmission mechanism connected between the motor and the smoke baffle and capable of converting the rotating action of the motor into the swinging action of the smoke baffle, and a hydraulic system connected with the transmission mechanism and used for providing resistance to the transmission mechanism to adjust the driving speed of the smoke baffle.

[0003] In the prior art, no matter whether water is boiled, cooked or stir-fried, the smoke baffle needs to be opened when the range hood is working. The design of the smoke baffle can effectively intercept the rising oil fume and reduce the risk of oil fume escape. However, at the same time, the smoke baffle in the opened state is horizontally arranged between the eyes of the user and the pot, which affects the user's observation of the cooking condition in the pot. SUMMARY

[0004] The first technical problem to be solved by the utility model is to provide a panel assembly for a range hood, so that a suitable oil fume suction mode can be selected according to the cooking condition and the oil fume suction effect is ensured.

[0005] The second technical problem to be solved by the utility model is to provide a range hood with the above panel assembly.

[0006] The technical solution adopted by the utility model to solve the above first technical problem is as follows: a panel assembly for a range hood, characterized by comprising:

[0007] A panel support has a front side plate extending downwardly and obliquely from front to back, an intermediate plate extending upwardly from the rear side edge of the front side plate, and a rear side plate extending obliquely downwardly from the upper edge of the intermediate plate. The front side plate is provided with a front air inlet penetrating the plate thickness thereof, and the rear side plate is provided with a rear air inlet penetrating the plate thickness thereof. The rear side plate and the intermediate plate jointly define a rear smoke inlet cavity with an opening facing downward, and the front side plate and the intermediate plate jointly define a front smoke inlet cavity with an opening facing upward.

[0008] A smoke baffle is arranged at the front air inlet in a front-rear flipping manner to open and close the front air inlet.

[0009] A ring suction plate is arranged at the opening of the rear air inlet cavity, and the edge of the ring suction plate and the edge of the corresponding opening of the rear air inlet cavity form a ring suction channel for the oil fume to enter the rear air inlet cavity.

[0010] When cooking or boiling water with a small amount of oil fume, the smoke baffle can be in a state of closing the front air inlet, at this time, the oil fume flows into the range hood through the ring suction channel and the rear air inlet in turn. Since the ring suction plate is located at the opening of the rear air inlet cavity, it is relatively low and close to the cooking pot, which can make the oil fume flow smoothly from the ring suction plate into the rear air inlet cavity, thereby ensuring the oil fume suction effect.

[0011] When cooking with a large amount of oil fume, the smoke baffle can be opened, at this time, the rising oil fume is sucked into the front air inlet, and part of the oil fume is still sucked into the ring suction channel, and the oil fume suction effect is better.

[0012] At the same time, since the smoke baffle is only arranged at the front air inlet, the front and rear lengths of the smoke baffle in the open state are relatively short, thereby avoiding blocking the user's view.

[0013] Preferably, the ring suction plate is inclined downward from front to back, and when the smoke baffle closes the front air inlet, the smoke baffle is inclined downward from front to back, and the rear side of the smoke baffle is spaced from the front side of the ring suction plate.

[0014] Further, the front side of the ring suction plate is located at the front side of the middle plate. In use, the oil stains can slide down along the plate surface of the front side plate and the middle plate to the upper plate surface of the ring suction plate.

[0015] Further, the extension length of the front side plate in the front and back direction is less than the extension length of the rear side plate; correspondingly, the length of the smoke baffle in the front and back direction when closing the front air inlet is less than the length of the ring suction plate in the front and back direction. Thus, the user's view can be further avoided when the smoke baffle is opened.

[0016] In the above scheme, preferably, the middle plate is inclined upward from bottom to top and rearward. The middle plate can also serve as a flow guide to promote the oil fume flow into the range hood.

[0017] In each of the above schemes, in order to facilitate the cleaning of the ring suction plate, the ring suction plate is preferably arranged in a manner that can be separated downward from the opening of the rear air inlet cavity.

[0018] In order to facilitate operation, the rear side plate and the ring suction plate are preferably constrained together by means of upper and lower buckling.

[0019] Further, the lower surface of the rear side plate is provided with a left and right extending rotating shaft, and the upper surface of the ring suction plate is provided with a hook, the hook portion of the hook is hung on the rotating shaft, so that the ring suction plate can rotate forward and backward relative to the rear side plate.

[0020] The upper surface of the ring suction plate and the rear side plate are respectively provided with a buckle and a hole matched with the buckle, so that the rear side plate and the ring suction plate are constrained together by the upper and lower buckling.

[0021] Further, the buckle and the hole are located at the front side of the hook and the rotating shaft.

[0022] The technical scheme adopted by the utility model to solve the second technical problem is: a range hood with the panel assembly as described above, characterized in that it further comprises a shell and a fan system, the panel assembly is arranged at the front side of the shell, and the fan system is arranged in the shell above the panel assembly and used for sucking oil fume into the shell through the front smoke cavity and the rear smoke cavity.

[0023] Preferably, it further comprises:

[0024] A first filter screen is arranged at the front air inlet of the front side plate.

[0025] A second filter screen is horizontally arranged in the shell above the rear side plate and below the fan system.

[0026] Preferably, it further comprises an oil cup arranged at the bottom of the shell and used for collecting oil stains in the shell, and the rear side edge of the ring suction plate extends above the oil cup and is opposite to the top opening of the oil cup. In this way, the oil stains on the surface of the ring suction plate can be collected in the oil cup after flowing downward.

[0027] Compared with the prior art, the utility model has the advantages that when cooking or boiling water with a small amount of oil fume, the smoke baffle can be in a state of closing the front air inlet, at this time, the oil fume flows into the range hood through the ring suction channel and the rear air inlet in turn, since the ring suction plate is located at the opening of the rear smoke cavity and is relatively low and close to the cooking pot, the oil fume can smoothly flow into the rear smoke cavity from the periphery of the ring suction plate in a short distance, thereby ensuring the oil fume suction effect.

[0028] When cooking with a large amount of oil fume, the smoke baffle can be opened, at this time, the rising oil fume is sucked into the range hood through the front air inlet, and part of the oil fume is still sucked into the range hood through the ring suction channel, so that the oil fume suction effect is better.

[0029] At the same time, since the smoke baffle is arranged only at the front air inlet, the front and rear lengths of the smoke baffle in the opened state are short, so that the user's vision is not blocked. BRIEF DESCRIPTION OF DRAWINGS
