Description

Technical Field

[0001] The invention relates to the technical field of range hoods, and in particular to a comprehensive range hood. Background Art

[0002] It is reported that in many large cities in China, residents' complaints about cooking fume pollution account for more than 40% of environmental pollution complaints. Cooking fumes contain many harmful ingredients, many of which are mutagenic and carcinogenic. Studies have shown that cooking fumes contain at least 200 chemical components. The incidence of lung cancer is closely related to kitchen fume emissions. If the cooking fume factor is eliminated, the incidence of lung cancer can be reduced by half.

[0003] The existing range hood or range hood treatment process for oil fume is as follows: the oil fume gas passes through the oil net and enters the hood air duct, and the oil fume gas is separated by the rotation of the turbine. The oil fume in the wind cabinet is subjected to the centrifugal force, and the oil mist condenses into oil droplets, which are collected in the oil cup through the oil path, and the purified smoke is finally discharged along a fixed path. The smoke after treatment in this way will still cause certain pollution to the environment.

[0004] Existing range hoods are equipped with a large-sized smoke collecting hood that can completely collect oil smoke, and are equipped with an oil collecting and exhausting device that is compatible with the smoke collecting hood and the smoke exhaust pipe. However, in actual use, the structure and installation characteristics of such range hoods are inconsistent with the smoke exhaust effect:

[0005] 1. When the range hood is installed at a higher position, the user has a good field of vision and cooking space, but the exhaust effect of the range hood is difficult to guarantee.

[0006] 2. When the range hood is installed at a lower position, the smoke exhaust effect of the range hood is better, but the user does not get enough cooking space, which may hinder cooking.

[0007] 3. In addition, the dimensions of different stoves are also different, which also have different effects on the spread of oil smoke. The range hood is set with a uniform installation height and position, which cannot be applied to a variety of different stoves. Summary of the invention

[0031] Beneficial Effects

[0032] Compared with the prior art, the comprehensive range hood proposed by the present invention has the following beneficial effects:

[0033] (1) In this technical solution, the kitchen fumes are first filtered through the condenser part, and part of the grease in the fumes is liquefied or solidified when it encounters the condenser, so that it is adsorbed on the condenser and drips into the oil collecting tank; then it is filtered for the second time through the oil-absorbing cotton in the oil collecting chamber, and the oil-absorbing cotton is used to absorb the grease in the fumes discharged from the air outlet duct; then the oil collecting chamber is indirectly cooled by a water tank, so that the fumes after the second filtration are further liquefied or solidified when they are discharged into the oil collecting chamber, and the fumes are precipitated and filtered for the third time; finally, the fumes are discharged, thereby purifying the grease in the fumes and reducing the grease discharged into the air.

[0034] (2) In the present technical solution, the condenser is configured to be in an inverted cone shape. Due to the characteristics of the liquid, the liquid flows along the condenser into the oil collecting tank, which facilitates the collection of grease on the condenser. The detachable oil-absorbing paper wrapped around the condenser facilitates disassembly and replacement, and effectively keeps the condenser clean, thereby reducing the number of cleaning times and replacement rate of the condenser.

[0035] (3) The submersible pump in the present technical solution increases the pressure on the condenser. When the range hood is started, the submersible pump is also started at the same time, and cooling liquid is supplied to the condenser from the water inlet pipe. The cooling liquid in the condenser returns to the water tank from the water outlet, so that the cooling liquid in the condenser and the cooling liquid in the water tank can be continuously circulated and replaced, so that the cooling liquid in the condenser is always kept at a low temperature, so that the condenser can continuously cool the oil smoke, and the grease in the oil smoke is cooled and condensed on the condenser, so as to filter the air carrying the oil smoke and reduce the discharge of grease.

[0036] (4) The detachable oil-absorbing cotton provided in the technical solution is convenient for replacement. The oil-absorbing cotton is arranged 2-5 cm away from the air outlet of the air outlet duct, which can effectively keep the air outlet duct unobstructed; and when the range hood is started, the pressure of the centrifugal fan on the oil smoke will cause the oil smoke in the air outlet duct to be sprayed onto the oil-absorbing cotton, and the oil-absorbing cotton will filter the oil smoke sprayed from the air outlet duct for the second time before entering the oil collecting chamber.

[0037] (5) The detachable drawer box provided in the oil collecting chamber in the technical solution is convenient for drawing out the waste oil and cleaning. Moreover, since the oil collecting chamber is adjacent to the water tank, which is filled with cold water, the overall temperature of the cold water can reduce the temperature of the oil collecting chamber or slow down the rate of temperature rise in the oil collecting chamber; after the oil smoke is discharged into the oil collecting chamber, it is cooled again, so that the oil in the oil smoke is further cooled and solidified, and falls into the drawer box of the oil collecting chamber.

[0038] (6) The position adjustment device in the present technical solution can be set to allow the range hood to be shifted within a small range, so that the range hood can not only remove the fumes from the cooking pot on the stove, but also be shifted to the electric pots placed next to the stove, such as the pressure cooker for making soup, the rice cooker, or the pots used on the induction cooker, etc., to remove the fumes, thereby increasing the use range of the range hood.

[0039] (7) In the technical solution, the upper crossbeam, the lower crossbeam, the telescopic bracket and the related components of the lead screw 1 are arranged so that the forward and reverse rotation of the lead screw 1 can drive the range hood to move up and down; the related components of the lead screw 2 are arranged so that the forward and reverse rotation of the lead screw 1 can drive the range hood to move left and right.

The centrifugal fan 3 includes an exhaust blade 32 arranged on the lower side and an exhaust fan cover 33 arranged on the upper side of the blade 32. A motor 34 that drives the blade 32 is provided on the upper side of the exhaust fan cover 33.

[0054] A condenser tube 2 connected to the centrifugal fan 3 is installed at the air inlet of the centrifugal fan 3; the condenser tube 2 is wrapped with a detachable oil-absorbing paper, which is easy to disassemble and replace, and effectively keeps the condenser tube 2 clean, reducing the cleaning frequency and replacement rate of the condenser tube 2.

[0055] The condenser tube 2 is a single or multiple water pipes that are continuously bent into an inverted cone shape, that is, the condenser tube 2 is arranged in a manner of having a large upper opening and a small lower opening. It adopts a fixed-shaped pipe to be continuously folded into a square, or a fixed-shaped pipe is arranged in a spiral shape.

[0056] The condenser pipe 2 arranged at the upper opening of the inverted cone can be fixed to the housing of the fan 3 by means of a buckle or a connector, which plays a further fixing role. The condenser pipe 2 arranged at the lower opening of the inverted cone is fixed by a fixing ring 241, and the outer side of the fixing ring 241 is connected to a detachable oil collecting tank 24 by a connecting device (such as a thread, a buckle or a locking device).
