Description
Technical Field
[0001] This utility model relates to an oil-removing range hood. Background Technology
[0002] Range hoods are one of the core appliances in modern kitchens. Their main function is to use a fan system to extract cooking fumes, steam, and odors, keeping the kitchen air clean. The range hood's inlet usually has a deflector to guide the fumes into the main body. The surface of the deflector adheres to a large amount of liquid grease or condensed oil droplets, causing grease to easily accumulate and solidify. Grease is particularly difficult to clean on the inner surface of the deflector, increasing the difficulty and frequency of subsequent cleaning.
[0003] In addition, most range hoods are equipped with an oil cup to collect oil droplets flowing back from the inner wall of the range hood casing. The oil droplets need to rely on the drainage structure inside the range hood casing to flow back to the oil cup located at the bottom of the range hood body. Some oil droplets accumulate and solidify on the drainage structure, which weakens the drainage effect and affects the collection of oil. Moreover, the oil cup is exposed below the baffle plate, causing stains to be exposed and potential odors to be emitted. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an oil-removing range hood that facilitates the removal of oil droplets from the surface of the baffle plate.

The air inlet groove is located outside the contour edge of the heating film and faces the smoke inlet. The volute fan can drive airflow from the air inlet groove and the air inlet gap into the smoke inlet.
[0012] In some embodiments of this utility model, one side of the clamping plate is provided with a bent plate portion facing the air inlet groove. The bent plate portion faces the inclined mounting plate from bottom to top so that the air inlet groove connects to the air inlet gap. The bent plate portion can block the overlapping part between the air inlet groove and the smoke inlet in the front-back direction.
[0013] In some embodiments of this utility model, the inclined mounting plate is provided with a drawer groove below the smoke inlet, and an oil cup is slidably arranged in the drawer groove along the front-back direction. When the guide plate is rotated to the unfolded state, the oil cup is exposed. The oil cup has an oil receiving groove with an upward opening.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0022] See Figures 1 to 3 This utility model discloses a range hood for removing oil stains, comprising: a range hood housing 100, an inclined mounting plate 110 inclined from top to bottom and rearward on the front side of the range hood housing 100, a smoke inlet 120 on the inclined mounting plate 110, a volute fan 200 inside the range hood housing 100, a smoke exhaust pipe 130 connected to the output end of the volute fan 200 on the top of the range hood housing 100, guide plates 300 spaced apart on the front side of the inclined mounting plate 110, the outer periphery of the guide plates 300 protruding from the outer periphery of the inclined mounting plate 110, an air intake gap defined between the guide plates 300 and the inclined mounting plate 110 and connected to the smoke inlet 120, and a planar heating element 400 laid on the inner surface of the guide plates 300.
[0023] The above-described oil-removing range hood has a planar heating element 400 on the inner surface of the baffle plate 300. When oil droplets adhere to the surface of the baffle plate 300 and solidify into grease after a period of time, the heating element 400 transfers heat to the baffle plate 300 to heat and melt the solid grease. This helps users remove oil droplets from both sides of the baffle plate 300 and can also evaporate condensate droplets on the baffle plate 300.
[0024] See Figure 2 and Figure 3In some embodiments of this utility model, the heating component 400 includes a heating film 410 attached to the inner surface of the guide plate 300. The length and width dimensions of the heating film 410 are adapted to the length and width dimensions of the guide plate 300. A clamping plate 420 is installed on the inner surface of the guide plate 300 to press the heating film 410 against the guide plate 300. The heating film 410 can be a carbon crystal heating element or a film with reciprocatingly bent metal wires. The clamping plate 420 and the guide plate 300 together clamp the heating film 410 to prevent it from falling off. The guide plate 300 is generally a good conductor of heat. When the guide plate 300 is made of steel, the clamping plate 420 can also be connected to the inner surface of the guide plate 300 by welding. Furthermore, the heating film 410 being located on the inner surface of the guide plate 300 does not affect the aesthetic appearance.
[0025] See Figure 2 and Figure 3 In some embodiments of this utility model, a control module 411 is connected to one corner of the heating film 410, and a clearance opening is provided on the clamping plate 420 corresponding to the control module 411. A control panel assembly 700 is provided on the upper side of the guide plate 300 above the heating film 410. The control module 411 is electrically connected to the control panel assembly 700, and the opening and closing of the heating film 410 can be operated on the control panel assembly 700.
[0026] See Figure 2 and Figure 3 In some embodiments of this utility model, in order to reduce the pollution of the atmosphere by flue gas emissions, a filter assembly 500 is detachably installed at the smoke inlet 120. To facilitate cleaning or replacement of the filter assembly 500, a guide plate 300 is rotatably mounted on the inclined mounting plate 110. The guide plate 300 can be rotated to an unfolded state to expose the filter assembly 500 or to a retracted state to cover the filter assembly 500 and form the air intake gap. In this embodiment, the filter assembly 500 is installed at the smoke inlet 120 via an elastic snap-fit assembly or a telescopic plug-in assembly. The elastic snap-fit assembly uses plastic or metal snap-fits, and the telescopic plug-in assembly uses a compression spring to drive the plug to extend and insert into the corresponding slot. Both the elastic snap-fit assembly and the telescopic plug-in assembly are existing technologies readily known to those skilled in the art and will not be further described here.
[0027] In some embodiments of this utility model, a bracket is provided at each of the two ends of the upper side of the inclined mounting plate 110, and the two ends of the upper side of the guide plate 300 are rotatably connected to the two brackets respectively. The lower side of the guide plate 300 and the lower side of the inclined mounting plate 110 are attracted and fixed by a magnetic attraction assembly. In this embodiment, the magnetic attraction assembly includes a first magnet fixed to the guide plate 300 and a second magnet fixed to the inclined mounting plate 110. The first magnet and the second magnet attract each other. When the user applies a certain external force to separate the first magnet and the second magnet, the guide plate 300 is driven to flip upward to clean the inner surface of the guide plate 300 and replace the filter assembly 500.
[0028] See Figures 1 to 3 In some embodiments of this utility model, the guide plate 300 is provided with an air inlet groove 310 extending along its length. The air inlet groove 310 is located outside the contour edge of the heating film 410 and faces the smoke inlet 120. The volute fan 200 can drive airflow from the air inlet groove 310 and the air inlet gap into the smoke inlet 120. It can be understood that some of the oil fumes can pass directly through the smoke inlet 120 through the air inlet groove 310 under the suction, thereby increasing the air intake channel and improving the efficiency of oil fume absorption.
[0029] See Figure 2 and Figure 3 In some embodiments of this utility model, one side of the clamping plate 420 is provided with a bent plate portion 421 facing the air inlet groove 310. The bent plate portion 421 extends from bottom to top towards the inclined mounting plate 110 so that the air inlet groove 310 connects to the air inlet gap. The bent plate portion 421 can block the overlapping portion between the air inlet groove 310 and the smoke inlet 120 in the front-back direction. It should be noted that the air inlet groove 310 is directly opposite a part of the smoke inlet 120. Users can directly see the oil stains inside the smoke inlet 120 through the air inlet groove 310, which affects the appearance. The setting of the bent plate portion 421 can solve this problem, and will not affect the entry of some smoke from the air inlet groove 310 into the smoke inlet 120.
[0030] See Figure 2 and Figure 3In some embodiments of this utility model, the inclined mounting plate 110 is provided with a drawer groove 140 below the smoke inlet 120. An oil cup 600 is slidably disposed in the drawer groove 140 along the front-back direction. When the guide plate 300 is rotated to the unfolded state, the oil cup 600 is exposed. The oil cup 600 has an upward-opening oil receiving groove 610. The bottom of the housing of the volute fan 200 is provided with an oil guide pipe 210 extending downward to the upper part of the oil receiving groove 610. It can be understood that when the fumes are discharged outward through the volute fan 200, a large amount of oil droplets will accumulate in the housing. Under the action of gravity, these oil droplets flow through the oil guide pipe 210 into the oil receiving groove 610 of the oil cup 600. When the guide plate 300 is rotated to the unfolded state, the user can pull the oil cup 600 out of the drawer groove 140 to empty the oil stains, which is convenient for cleaning. Moreover, the oil cup 600 will not be exposed when the range hood is working, which is more aesthetically pleasing.
[0031] See Figure 3 In some embodiments of this utility model, in order to increase the capacity of the oil cup 600 to receive oil droplets, the drawer groove 140 and the oil cup 600 are both extended along the length direction of the inclined mounting plate 110. The inner side of the inclined mounting plate 110 is provided with a frame plate 150 for supporting the oil cup 600. In order to facilitate the user to manually pull out the oil cup 600, the front side of the oil cup 600 is provided with a handle 620.
[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
