Abstract
Description
Technical Field
[0001] The utility model relates to the field of kitchen and bathroom, in particular to an oil collecting plate at the rear of an oil fume machine and the oil fume machine. Background Technique
[0002] An oil fume machine is a kitchen utensil that separates oil and fume to achieve the effects of oil absorption and fume collection. It usually includes an oil fume separation device and an air inlet device. In the oil fume separation device, the oil collecting plate is usually provided with an open filtering cavity and an air inlet on the filtering cavity for separating oil fume. During use, the air inlet device sucks the oil fume from the surrounding into the filtering cavity. The grease condenses on the cavity wall of the filtering cavity and slides down into the oil collecting tank below, while the smoke is continuously sucked into the oil fume machine through the air inlet, thereby realizing the separation of oil fume.
[0003] However, the cavity walls of the filtering cavity of the existing oil collecting plate of the oil fume machine are all flat planes. On the one hand, the contact area between the oil fume and the filtering cavity is limited and the contact time is short, so the oil fume collection is not sufficient. On the other hand, since the flat plane has no influence on the speed of the oil fume, the air inlet speeds of the gas and particulate matter in the oil fume are the same, and it is difficult to separate the smoke and grease. The structure of the filtering cavity of the oil collecting plate urgently needs to be improved. Summary of the Utility Model
[0004] The first object of the utility model is to overcome the deficiencies of the existing oil collecting plate structure. A corrugated or concave-convex oil collecting structure is arranged on the oil collecting plate, which not only increases the air inlet area, makes the contact area between the oil fume and the oil collecting plate larger and the contact time longer, and the oil fume collection is more sufficient, but also the corrugated or concave-convex structure can change the wind speed to form a vortex, increasing the disturbance of the wind. Since the disturbance inertia of the gas is greater than that of the particulate matter, the turning speed of the gas is greater than that of the particulate matter, that is, the speed of the smoke is greater than that of the grease, so as to achieve the effect of oil fume separation.
[0005] In order to achieve the above object, the present invention adopts the following technical solutions:
[0006] An oil collecting plate at the rear of an oil fume machine includes a body, an inwardly concave filtering cavity is provided on the body, an air inlet and an oil collecting structure are provided on the filtering cavity, the air inlet is located in the middle of the filtering cavity, and the oil collecting structure is arranged on both sides of the air inlet.
[0007] By arranging an oil collecting structure in the filtering cavity of the oil fume machine, the utility model not only increases the area of condensing and adsorbing grease, but also can increase the disturbance of the wind, so that the oil fume is separated under the difference of the disturbance inertia of the gas and particulate matter, and thus the oil collection is sufficient. Compared with the prior art, the oil collecting plate at the rear of the oil fume machine of the utility model has more sufficient oil fume separation and better effect.
[0008] Preferably, the oil collecting structure includes a plurality of oil collecting grooves which extend along the width direction of the air inlet. On the one hand, the flat surface of the oil collecting plate is changed into an uneven surface, increasing the area for condensing and adsorbing grease on the oil collecting plate, and making the grease condensation more sufficient. On the other hand, when the incoming air encounters the uneven surface, the wind pressure around it will change correspondingly due to the unevenness of the surface, changing the wind direction and increasing the disturbance of the wind, thereby making the smoke absorption more sufficient.
[0009] Preferably, there is a smooth transition between adjacent oil collecting grooves, and the whole is in a continuous corrugated shape, or adjacent oil collecting grooves are concave or convex with respect to the filtering cavity, and the oil collecting grooves are evenly distributed along the length direction of the air inlet. The corrugated structure or the concave-convex structure can increase the structural strength of the oil collecting plate, keep the oil collecting plate unchanged in shape under the wind pressure of the air inlet device, and increase the service life.
[0010] Preferably, the main body is provided with a suction part which is inclined, and the inclination angle is -1° to 0.5°, and the filtering cavity is arranged on the suction part.
[0011] Preferably, the peak value of the wave of the oil collecting structure is 1 mm to 6 mm, and the trough value of the wave is 1 mm to 6 mm.
[0012] Preferably, the cross-section of the filtering cavity is trapezoidal, and the distance between the filtering cavity and the suction part is 55 to 65 mm, providing sufficient space for the disturbance of the wind, so that the oil fume is fully separated and collected in the filtering cavity.
[0013] Preferably, the left and right sides of the filtering cavity are provided with a first inclined surface, the upper side is provided with a second inclined surface, and the lower side is provided with a third inclined surface. The inclination angle of the first inclined surface is 110° to 130°, the inclination angle of the second inclined surface is 125° to 145°, and the inclination angle of the third inclined surface is 100° to 120°. The inclination angle of the wall of the filtering cavity is set to an obtuse angle with a gentle slope, guiding the grease to slide down along the wall of the cavity, avoiding the grease dripping directly under the action of gravity due to too small an inclination angle and not being able to enter the oil collecting groove of the range hood, resulting in the grease dripping on the stove top and increasing the cleaning difficulty.
[0014] Another object of the present invention is to provide a range hood, including a range hood body and the rear oil collecting plate of the range hood in the above scheme. The range hood body is provided with an inclined baffle plate, and the baffle plate is a double-layer perforated plate structure. The baffle plate is provided with filtering holes, and the baffle plate is used for blocking the wind and absorbing oil. The baffle plate is adaptively arranged on the side of the air inlet facing the filtering cavity and is balanced with the suction part.
[0015] Compared with the prior art, since the above scheme is applied to the range hood of the present invention, the air inlet area is increased and the disturbance of the wind is increased, and a better oil fume separation and collection effect can be achieved.
[0016] Preferably, insertion members and hook connection assemblies are symmetrically arranged on one side of the suction part facing the oil baffle, insertion protrusions and hook connection members are symmetrically arranged on one side of the oil baffle facing the suction part, the insertion protrusions are connected to the insertion members, and the hook connection members are hooked to the hook connection assemblies.
[0017] Preferably, the range hood body includes an oil collecting tank, the collecting tank is arranged below the suction part, and the notch of the collecting tank is arranged on one side close to the filtering cavity, so that the grease slides down from the filtering cavity and then enters the collecting tank along the cavity wall.
