Drawings
Fig. 1 is a schematic structural view of an embodiment of a protective screen for lampblack, which is convenient to clean and provided by the invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a schematic structural view of a conveniently cleaned oil smoke protection net provided by the present invention.
A convenient-to-clean oil smoke protection net is installed on a shell 1, in order to describe the working state of the whole oil smoke exhaust ventilator, a smoke exhaust ventilator 2 is further included in an attached drawing, and the smoke exhaust ventilator 2 extracts oil smoke generated during cooking. A kind of soot protective screen easy to wash includes: a fume filtering device 3 and a cleaning device 4. The oil fume filtering device 3 intercepts small-particle oil droplets in oil fume, and the cleaning device 4 cleans oil stain and oil dirt on the oil fume filtering device 3.
An air inlet (not marked) and an air outlet 11 are arranged on the shell 1, the air outlet 11 is communicated with a flue in a kitchen, and the air inlet is opposite to a cooking bench. The oil smoke generated during cooking enters the air inlet hole and is discharged into the flue through the air outlet hole 11.
The cooking hood 2 includes a working motor 21 and a fan 22. The fan 22 is arranged towards the air inlet and connected with a rotating shaft of the working motor 21, can rotate at a high speed under the driving of the working motor 21, generates suction force to suck oil smoke generated during cooking into the shell 1 from the air inlet, and discharges the oil smoke into the flue through the air outlet 11. In order to prevent the soot from adhering to the working motor 21 and damaging the working motor 21, it is preferable that the working motor 21 is disposed outside the housing 1, and a rotation shaft thereof extends through the housing 1 into the housing 1 to be connected to the fan 22, so as to prevent the soot from adhering to the working motor 21.
The oil smoke filtering device 3 includes a filter screen 31, a base 32, and an oil collecting box 33. The filter screen 31 is an inverted cone, the upper end of the filter screen is connected with the edge of the air inlet, the lower end of the filter screen is connected with the base 32, the oil accumulation box 33 is detachably connected with the base 32, and the connection mode can adopt common connection modes such as buckle connection and threaded connection. The filter screen 31 is provided with a plurality of small holes, when oil smoke enters the shell 1 from the air inlet, the oil smoke needs to pass through the filter screen 31, the filter screen 31 can intercept a part of small oil droplets in the oil smoke in the process, the small oil droplets are attached to the filter screen 31, and after the small oil droplets are accumulated to a certain degree, the small oil droplets flow down along the filter screen 31 under the action of gravity and flow into the oil accumulation box 33 through the outer wall of the base 32, and the oil accumulation box 33 can be taken down for cleaning after the oil accumulation box 33 collects enough oil. In order to enable the intercepted oil to smoothly flow down without occupying a large volume, the screen 31 is preferably inclined downward at an angle of 30 ° to 60 °, and in this application, the inventor has made experiments several times to take an optimum angle of 40 °. In order to better facilitate the collection of the oil intercepted by the filter screen 31, the oil collecting box 33 is preferably detachably connected to the bottom of the base 32 and has a size larger than that of the base 32, so that the oil dripping from the outer wall of the base 32 does not fall out of the oil collecting box 33.
The cleaning device 4 includes a cleaning motor 41, a brush plate 42, bristles 43, a heating lamp 44, and a protective glass 44. The cleaning motor 41 is mounted on the base 32, and in order to better mount the cleaning motor 41 on the base 32 and reduce the adverse effect of the oil smoke on the cleaning motor 41, preferably, a mounting hole is formed in the upper surface of the base 32, the cleaning motor 41 is embedded in the mounting hole, and the rotating shaft extends upwards out of the mounting hole. Because the base 32 covers most of the structure of the cleaning motor 41, the adverse effect of the oil smoke on the cleaning motor 41 is greatly reduced. One end of the scrubbing brush 42 is connected with a rotating shaft of the cleaning motor 41 and is arranged in parallel with the filter screen 31 at intervals, the upper end of the brush hair 43 is connected with the scrubbing brush 42, the lower end of the brush hair 43 is abutted against the filter screen 31, the cleaning motor 41 can drive the scrubbing brush 42 and the brush hair 43 to rotate, the brush hair 43 brushes and cleans the filter screen 31 in the rotating process, and oil stain and oil dirt attached to the filter screen 31 is brushed down to flow down along the filter screen 31 and flow into the oil accumulation box 33. In daily use, it is impossible to clean the filter net 31 after each use, and therefore, oil droplets caught on the filter net 31 are mixed with dust in the air and are condensed on the filter net 31 after being oxidized by oxygen in the air, increasing difficulty in cleaning, and therefore, it is preferable to provide a heating lamp 44 in the housing 1. The heating lamp 44 is arranged towards the filter screen 31, the working principle of the heating lamp is an electric heating principle, the electric heating tube is heated to a red hot state by electric energy, the electric heating tube is enabled to emit a large amount of infrared rays towards the filter screen 31, the filter screen 31 is heated by a heat radiation mode, oil stains and oil stains on the filter screen 31 are heated and softened, and the cleaning is facilitated. In order to prevent the soot sucked in from adhering to the electric heating tube of the heating lamp 44 during use and damaging the electric heating tube. Therefore, it is preferable to provide a protective glass 45 on the surface of the heating lamp 33 to isolate the electric heating tube of the heating lamp 44 from the soot, thereby preventing the soot from adhering to the electric heating tube. During actual use, oil smoke can be attached to the protective glass 45, and when the heating lamp 44 is used, the generated infrared rays can heat oil stains attached to the protective glass 45, so that the oil stains are heated, liquefied and dripped, and the self-cleaning effect is achieved.
This smoke ventilator with clearance function uses after a period, when needing to clear up filter screen 31, can manually spray the detergent on filter screen 31 to promote the clearance of greasy dirt. Meanwhile, the heating lamp 44 heats the filter screen 31 to promote the oil stain and oil dirt to be softened. After the preparation is completed, the cleaning motor 41 is started to drive the brush 43 to rotate to wash the filter screen 31, so that the oil dirt and oil droplets on the filter screen 31 flow into the oil accumulating box 33 along the filter screen 31.
The embodiment of the invention has the following beneficial effects: the oil smoke protective screen convenient to clean is provided with the cleaning device, the cleaning brush can rotate under the driving of the cleaning motor to clean the filter screen, oil stain and oil dirt attached to the filter screen are brushed down to flow into the oil accumulation box along the filter screen, the labor intensity in the process of cleaning the filter screen is greatly reduced, and the filter screen is easier to clean.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
