Description
Technical Field
[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a high-power cleaning-free range hood. Background Art
[0002] Range hoods are electrical appliances used in family kitchens to remove fumes produced during cooking. They not only fulfill their functional functions, but also have decorative concepts that integrate with modern kitchen layouts. With the development of range hoods, range hoods are no longer limited to simple tools for removing fumes in the kitchen, but have added more entertainment functions and usage functions, such as entertainment range hoods with TV monitors, range hoods with security systems integrated with smart homes, and network range hoods with network control.
[0003] When the existing range hood is extracting oil fumes, the oil fumes will come into contact with the panel of the range hood. Since the temperature of the panel is lower than the temperature of the high-temperature oil fume, when the oil fume comes into contact with the lower temperature surface of the panel, the vaporized oil fume and small particles of grease will settle and condense on the panel. When the settled and condensed small particles of oil, gas and grease continue to gather, a large area of difficult-to-remove oil stains will be formed on the surface of the panel, which requires people to clean, bringing great challenges to the cleaning work.

The walls are all equipped with second jet pipes 12, the outside of the first jet pipe 10 is provided with a plurality of first water outlets 15 facing one side of the two guide plates 2, the outside of the second jet pipe 12 is provided with a plurality of second water outlets 13 facing the inner wall of the annular water tank 3, the two guide plates 2 are arranged obliquely, when the water flow is sprayed on the lower slope of the guide plate 2, the guide plate 2 will automatically guide the water flow so that the water flows down along the inner wall, the first water outlet 15 and the second water outlet 13 are both fine holes, and the sprayed water is in the form of mist, a drain pipe 7 is installed at the bottom of the annular water tank 3, and a valve is installed on the outside of the drain pipe 7. When use is finished, the shutdown button is pressed, The control panel opens the valve to drain the mixed oily and sewage water and waits for the next startup cycle. The inner wall of the annular water tank 3 is installed with a water level sensor 8 located above the bottom of the baffle 4. The water level in the annular water tank 3 can be controlled by the water level sensor 8. The inside of the annular water tank 3 is installed with a water inlet solenoid valve 9 located above the water level sensor 8. The water inlet of the water inlet solenoid valve 9 extends to the outside of the annular water tank 3 through a connecting pipe. When the filtered water in the annular water tank 3 is sufficient, the water inlet solenoid valve 9 is closed, and a water circulation is formed inside through the water pump 14 for continuous cleaning. When the water volume is lower than the water level requirement , the water inlet solenoid valve 9 is automatically opened for water injection, the water inlet solenoid valve 9 is connected to an external water source, a water pump 14 is provided on the outside of the shell 1, the water outlet of the water pump 14 is connected to the first jet pipe 10 through the water outlet pipe, the water inlet of the water pump 14 is connected to the annular water tank 3 through the water inlet pipe, and the two second jet pipes 12 are connected to the first jet pipe 10 through the connecting pipe 17.

[0025] It should be noted that when this high-power cleaning-free range hood is in use, the water pump 14 is started, and water is pressurized into the first jet pipe 10. The liquid entering the first jet pipe 10 will pass through the connecting pipe 17 to the inside of the two second jet pipes 12.

[0026] Example 2
[0027] like Figure 1 - Figure 8 As shown, the difference between this embodiment and embodiment 1 is that a filtering mechanism is installed between the two baffles 4 and the outer shell 1, wherein the filtering mechanism includes a plurality of filter plates 5 installed between the inner wall of the outer shell 1 and the baffle 4, and a plurality of mesh holes 6 opened on the filter plates 5, and the mesh holes 6 on every two adjacent filter plates 5 are staggered, and the plurality of filter plates 5 need to be always immersed below the water surface, and the overall position is above the lower end of the baffle 4 and below the water surface, and the main purpose is to separate small bubbles and improve the filtering effect of oil smoke.
[0028] The further improved feature of this embodiment is that after the fan rotates, a negative pressure is formed between the guide plate 2 and the shell 1, causing the liquid level at the bottom between the shell 1 and the guide plate 2 to rise, and the liquid level at the bottom of the guide plate 2 and the baffle 3 to drop. When the liquid level is lower than the bottom edge of the baffle 4, the inhaled oil fume airflow will pass through the multiple mesh holes 6 on the filter plate 5 along the bottom edge of the baffle 4, and be divided into small bubbles and overflow. The particles and odors in the oil fume are adhered and filtered by the cleaning agent, and then discharged by the fan through the ventilation duct formed between the shell 1 and the guide plate 2, completing the purification process.
[0029] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
