Description

Technical Field

[0001] The utility model relates to the field of range hoods, and particularly to a water curtain device for filtering cooking fumes. Background Art

[0002] The integrated inner - circulation cooking fume purifier is a new - type range hood with two functions of inner - circulation and purification. The inner - circulation is to recycle the cooking fumes indoors through certain technical means, thereby reducing the dependence on outdoor air. The purification is to perform multiple filtrations on the cooking fumes through efficient purification technologies, and finally effectively remove the harmful substances therein, which can improve the air quality in the kitchen and reduce the pollution to the outdoor environment at the same time.

[0003] The existing purification method of the integrated inner - circulation cooking fume purifier usually uses an oil - separating disc for mechanical oil removal, and then cooperates with an electrostatic field device for electrostatic adsorption and high - voltage ionization to achieve the purpose of purifying cooking fumes. However, after using such an integrated machine for a period of time, a large amount of oil stains will adhere to the position of the oil - separating disc, and it needs to be cleaned regularly. Due to the large difficulty in disassembling the oil - separating disc and the high cleaning difficulty, it causes inconvenience in use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a water curtain device for filtering cooking fumes. The device forms a water curtain layer on the mesh holes of the mesh plate by the impact of water flow with a certain flow rate on the water - retaining plate. The cooking fume particles and cooking fume droplets in the cooking fumes can be absorbed by the water curtain layer and carried away by the flowing water, thus having the advantage of lower cleaning difficulty.

[0005] The technical solution adopted by the utility model to solve the above problems is:

[0006] A water curtain device for filtering cooking fumes, which is applied to the housing of a range hood, includes a water guide pipe and a mesh plate. Both the water guide pipe and the mesh plate are arranged in the air inlet of the range hood housing. The mesh plate is provided with a number of mesh holes, a water - retaining plate is arranged in the middle position of the mesh plate, and the water outlet of the water guide pipe is located above the water - retaining plate.

[0007] In the above - mentioned technical solution, preferably, the mesh plate includes a frame, an upper mesh plate and a lower mesh plate. The upper mesh plate and the lower mesh plate are both provided with mesh holes with the same specifications and corresponding positions up and down. The upper mesh plate is fixed in the frame. The water - retaining plate is arranged on the upper mesh plate. The lower mesh plate is slidably arranged left - and - right in the frame, and the lower surface of the lower mesh plate is attached to the lower side of the upper mesh plate.

[0008] In the above - mentioned technical solution, preferably, a water tank is arranged in the housing and the water tank is located below the mesh plate. The lower end of the water guide pipe is connected with a water pump and the water pump is placed in the water tank.

[0009] In the above technical solution, preferably, a water inlet, an overflow port and a drain port with a valve are provided at the bottom end of the water tank, and the upper end of the overflow port is lower than and close to the upper opening of the water tank.

[0010] In the above technical solution, preferably, a float valve is provided on the water inlet.

[0011] In the above technical solution, preferably, a baffle is provided on the front side of the water conduit and the mesh plate, and the baffle is detachably fixed to the range hood housing.

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] See Figures 1 - 3 Figures 1 - 3 , the water curtain device for filtering oil fume in this embodiment is applied to the oil fume machine housing 1, and includes a water guide pipe 2 and a net plate 3. Both the water guide pipe 2 and the net plate 3 are arranged in the air inlet 11 of the oil fume machine housing 1. The net plate 3 is provided with a plurality of mesh holes 31, a water baffle 32 is arranged at the middle position of the net plate 3, and the water outlet 21 of the water guide pipe 2 is located above the water baffle 32.

[0021] Existing oil fume machines and internal circulation oil fume purification integrated machines usually set an exhaust device (such as a fan) in the machine body to suck oil fume from the air inlet of the machine body, which is a conventional technical means in the art.

[0022] When the present utility model is in use, the air inlet 11 of the oil fume machine housing 1 sucks in oil fume, and the oil fume moves towards the net plate 3. At the same time, a water flow with a certain flow rate is ejected downward through the water guide pipe 2. The water flow hits the water baffle 32 downward and spreads around the water baffle 32, so as to form a water curtain layer on the mesh holes 31 of the net plate 3. When the oil fume moves upward through the mesh holes 31, the oil fume particles and oil fume droplets in the oil fume can be absorbed by the water curtain layer and carried away by the flowing water, playing a role in absorbing the oil fume particles and oil fume droplets. Therefore, the present utility model absorbs most of the oil fume particles and oil fume droplets in the oil fume through the water curtain layer, thereby reducing the rate of oil stain accumulation on the electrostatic field module, and the oil stains absorbed by the water curtain layer can be conveniently discharged from the housing mixed with water, with a lower cleaning difficulty, improving the convenience of using the present utility model.

[0023] In the present utility model, the structures of the water guide pipe 2 and the net plate 3 are simple, and a relatively thin flowing water curtain layer can be formed on the mesh holes 31 of the net plate 3. While ensuring the absorption effect on the oil fume particles and oil fume droplets, it can also reduce the hindrance to the oil fume gas and ensure the fluidity of the gas in the oil fume machine housing 1.

[0024] See Figure 3 Figure 3 , the net plate 3 includes a frame 33, an upper net plate 34 and a lower net plate 35. The upper net plate 34 and the lower net plate 35 are both provided with mesh holes 31 with the same specifications and corresponding upper and lower positions. The upper net plate 34 is fixed in the frame 33. The water baffle 32 is arranged on the upper net plate 34. The lower net plate 35 is slidably arranged left and right in the frame 33, and the lower net plate 35 is attached to the lower side of the upper net plate 34.

[0025] Due to the differences in the amount of cooking fumes generated, and the fact that the exhaust device inside the range hood housing 1 generates significant noise during operation, and the water flow discharged from the water conduit 2 also generates noise when the water flow rate is high. Therefore, when the amount of cooking fumes generated is small, while ensuring that the smoke inhalation speed and the water output of the water conduit 2 can effectively absorb the oil fume particles and droplets, the power of the exhaust device and the water output speed of the water conduit 2 can be appropriately reduced, thereby reducing the noise formed by the exhaust device and the water flow. At the same time, by moving the lower mesh plate 35, the mesh holes 31 on the upper mesh plate 34 and the lower mesh plate 35 are gradually staggered, so that the path through which the oil fumes pass becomes narrower, reducing the situation where water directly leaks through the mesh holes 31 when the water flow rate is slow, ensuring that the water flow can form a water curtain layer on the mesh plate 3, and thus ensuring the absorption effect of the present invention on the oil fume particles and droplets.

[0026] See Figure 1 、 Figure 2 , a water tank 12 is provided inside the housing and the water tank 12 is located below the mesh plate 3. The lower end of the water conduit 2 is connected to a water pump 4 and the water pump 4 is placed inside the water tank 12.

[0027] The water conduit 2 sucks water upward from the water tank 12 through the water pump 4, so as to eject a water flow with a certain flow rate from the water outlet 21 of the water conduit 2. After the water flow forms a water curtain layer on the mesh plate 3, it flows back into the water tank 12 again, enabling the water stored in the water tank 12 to be recycled, reducing the water consumption of the present invention, and thus reducing the cost during the use of the present invention.

[0028] See Figure 1 、 Figure 2 , the bottom end of the water tank 12 is provided with a water inlet 13, an overflow port 14 and a drain port 15 with a valve. The upper end of the overflow port 14 is lower than and close to the upper opening of the water tank 12.

[0029] The water inlet 13 at the bottom end of the water tank 12 can be connected to a water supply pipeline (such as a water valve in the kitchen) through a water pipe for water supply. At the same time, the overflow port 14 is used to ensure that the water in the water tank 12 will not be too much and overflow from the edge of the water tank 12; when the water in the water tank 12 is recycled for a period of time, the sewage in the water tank 12 can be discharged by opening the valve on the drain port 15, improving the convenience of using the present invention.

[0030] See Figure 2 , a float valve 16 is provided on the water inlet 13.

[0031] The float valve 16 can automatically judge the water volume in the water tank 12. When the water volume in the water tank 12 is too low, the float valve 16 can be automatically opened to inject water into the water tank 12, and when the water volume reaches the standard, the float valve 16 can be automatically closed to stop the water injection, reducing the cumbersome degree of operation during the use of the present invention.

[0032] See Figure 1 and Figure 2 , a baffle 5 is provided on the front side of the water guide pipe 2 and the mesh plate 3, and the baffle 5 is detachably fixed to the range hood housing 1.

[0033] The baffle 5 plays a role in shielding the water guide pipe 2 and the mesh plate 3, which can reduce the probability of water splashing outside the range hood housing 1 when the water hits the water baffle 32. At this time, the mesh plate 3 can be directly inserted into the corresponding installation position in the range hood housing 1, and then the baffle 5 is fixed in front of the mesh plate 3 to realize the installation of the mesh plate 3, making the installation operation of the mesh plate 3 simple and facilitating the disassembly and cleaning operation of the mesh plate 3.

[0034] See Figure 1 and Figure 2 , a hanging plate 6 is provided below the mesh plate 3. The hanging plate 6 is fixed to the inside of the range hood housing 1 through a bracket. The hanging plate 6 is inclined with the front end higher and the rear end lower, and the rear end of the hanging plate 6 extends into the upper opening of the water tank 12.

[0035] When water flows down from the mesh plate 3, part of the water directly falls into the water tank 12, and the other part of the water falls onto the hanging plate 6 and flows into the water tank 12 under the action of the hanging plate 6, ensuring that the front and rear width of the mesh plate 3 is larger to increase the passage area of the flue gas while reducing the front and rear width of the water tank 12 and reducing the risk of interference with the cooking area caused by the excessive front and rear width of the water tank 12.

[0036] The above content described in this specification is only an example of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, as long as they do not deviate from the content of this specification of the present utility model or exceed the scope defined by this claim book, they shall fall within the protection scope of the present utility model.
