Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and in particular to a grease adsorption module and a range hood. Background Art

[0002] At present, kitchens generally use range hoods to discharge cooking fumes and purify the indoor environment. Ideally, the fume particles enter the range hood with the air and are intercepted and separated by the filter, impeller and other components and flow into the oil cup. However, in actual work, due to the high viscosity of oil, it is easy to adhere to the impeller and the inside of the volute after condensation. If it is not cleaned for a long time, it will form grease and oil film, affecting the performance of the range hood.

[0003] At present, there are two main installation positions for electrostatic adsorption devices for oil fume treatment. One is to install it after the range hood is exhausted to treat oil fume to avoid polluting the environment. This method is mainly used for commercial oil fume. The other is to install it between the air inlet of the range hood and the fan to protect the rear fan, maintain the performance of the rear fan, reduce or even eliminate the cleaning of the rear fan. Compared with the static filter, this oil fume separation method has a smaller pressure drop and a higher grease capture efficiency.

[0004] However, most of the current grease electrostatic adsorption devices use plates that are installed on the brackets and connected with connecting rods and other connectors to conduct electricity. This design method has many components, is troublesome to assemble, and has low efficiency. Secondly, the sparse plate setting in the electrostatic adsorption device will lead to low grease adsorption efficiency. The overly dense plate setting will have a certain risk of scaling and clogging, resulting in a decrease in adsorption efficiency, affecting the long-term use of the electrostatic adsorption device, and the pressure loss is large; for example, a simple ordinary square flat plate structure is used as a plate to ionize grease, which not only has low physical filtration efficiency, but also requires a higher voltage for the same ionization intensity of grease. Secondly, the electrostatic adsorption device currently installed between the air inlet of the range hood and the fan basically has no structure that allows the adsorbed grease to flow more smoothly and uniformly into the oil cup, resulting in the adsorbed grease either scaling on the plate or randomly dripping back into the smoke collecting chamber. And this installation method is basically horizontal installation, and the path of oil smoke from the electrostatic adsorption device to the air inlet of the fan is too tortuous, resulting in greater resistance.

[0005] Therefore, a solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] At present, there are two main installation positions for electrostatic adsorption devices for oil fume treatment. One is to install it after the range hood is exhausted to treat the oil fume to avoid polluting the environment. This method is mainly used for commercial oil fume. The other is to install it between the air inlet of the range hood and the fan to protect the rear fan, maintain the performance of the rear fan, reduce or even eliminate the cleaning of the rear fan. Compared with the static filter, this oil fume separation method has a smaller pressure drop and a higher grease capture efficiency.

[0044] However, the existing adsorption device has the following technical defects:

[0045] (1) Currently, most electrostatic adsorption devices are designed to install individual plates on a bracket and use connecting rods and other connecting parts to conduct electricity. This design method has many parts, is difficult to assemble, and has low efficiency.

[0046] (2) In the electrostatic adsorption device, too sparse plate arrangement will lead to low grease adsorption efficiency. On the other hand, too dense plate arrangement will have a certain risk of scaling and clogging, resulting in reduced adsorption efficiency, affecting the long-term use of the electrostatic adsorption device, and causing large pressure loss.

[0047] (3) When a simple ordinary square flat plate structure is used as an electrode plate to ionize grease, not only the physical filtration efficiency is low, but also the voltage required for the same ionization intensity of grease is high.

[0048] (4) The electrostatic adsorption device currently installed between the air inlet of the range hood and the fan basically has no structure to make the adsorbed grease flow more smoothly and uniformly into the oil cup, resulting in the adsorbed grease either scaling on the plate or randomly dripping back into the smoke collecting chamber. In addition, this installation method is basically horizontal, and the path of the oil smoke from the electrostatic adsorption device to the fan inlet is too tortuous, resulting in greater resistance.

[0049] In order to solve at least one of the above-mentioned technical problems, the embodiment of the present application provides a grease adsorption module and a range hood. The grease adsorption module is applied to the range hood and can solve the technical problem of poor performance of the range hood caused by the complex components of the existing grease electrostatic adsorption device.

[0050] Specifically, Figures 1 to 25 to 6, the embodiment of the present application provides a grease adsorption module, which is applied to a range hood. The grease adsorption module includes an ionization zone component, which is arranged in the range hood, including an ionization zone bracket 3, an ionization plate 1 and an ionization frame 2. The ionization zone bracket 3 is provided with a first accommodating groove, and the ionization plate 1 is arranged in the first accommodating groove. The ionization plate 1 is provided with a plurality of discharge electric tips 101, and a plurality of first high-voltage conductive rods 102 corresponding to the discharge tips 101, each of which is provided with a first high-voltage conductive rod 102. The rod 102 can electrically connect each discharge discharge tip 101, and the discharge tip 101 is integrated with the first high-voltage conductive rod 102 on the ionization plate 1 and is integrally arranged with the ionization plate 1; the ionization frame 2 is arranged in the first accommodating groove, and the cover is arranged on the ionization plate 1, and the ionization frame 2 is provided with a second high-voltage conductive rod 201 vertically connected to the first high-voltage conductive rod 102, and the second high-voltage conductive rod 201 can electrically connect a plurality of discharge discharge discharge tips 101, and the second high-voltage conductive rod 201 is integrated with the ionization frame 2 and is integrally arranged with the ionization frame 2.

[0051] In the embodiments of the present application, Figures 1 to 2 As shown, the ionization region has three components, namely, an ionization plate 1, an ionization frame 2 and an ionization region support 3.

[0052] The ionization plate 1 is formed by stamping and bending in one piece, and the material of the ionization plate 1 is directly used to generate the electrode plate, which is composed of a plurality of right-angled triangles to form a discharge tip 101. Two electrode plates are arranged in parallel and spaced apart as a group, and the discharge tip 101 of the opposite electrode plate is formed by bending the right-angled triangles that fit each other. An ionization plate 1 contains multiple electrode plates, which not only saves materials, but also increases the number of tips and improves the ionization intensity. In this embodiment, the angle of the discharge tip 101 should be less than one-fourth of the other acute angle of the right triangle to ensure the strength while increasing the number of tips as much as possible. The square holes left after the electrode plate is bent and the square holes left by stamping and cutting between the electrode plate groups are arranged at intervals along the width direction of the range hood to form the smoke inlet of the ionization zone. The interval between each inlet is the distance of the first high-voltage conductive rod 102. The first high-voltage conductive rod 102 is not only used to connect each electrode plate for conduction, but also can be used as a static filter 11 to intercept part of the grease and increase the separation efficiency.

[0053] The ionization frame 2 is also formed by stamping and bending in one piece, and the material of the ionization frame 2 is directly used to form the plate, and the square hole left after stamping and bending serves as the outlet of the flue gas in the ionization zone. The shape of the plate can fit the square hole and is also square. Similarly, each outlet of the ionization frame 2 is separated by a second high-voltage conductive rod 201, which can not only connect each plate for conduction, but also serve as a static filter to intercept and capture grease by inertia. The overall structure is simple and easy to process.

[0054] The ionization zone bracket 3 is made of insulating material and is used to fix the ionization plate 1 and the ionization frame 2. A groove is provided on the upper end for the ionization frame 2 to cover and install on the ionization plate 1. After assembly, the pole plates of the ionization plate 1 and the ionization frame 2 are staggered, and the distance between them is the same. The first high-voltage conductive rod 102 and the second high-voltage conductive rod 201 are also staggered in the width direction of the smoke machine, resulting in each inlet of the ionization zone being between two square outlets, which strengthens the bypass of the flue gas through the ionization zone and improves the efficiency of physical interception.

[0055] In a preferred example, the tip of the discharge tip 101 is arranged toward the ionization frame 2. Specifically, the discharge tip 101 points toward the interior of the cabinet 7 of the range hood, so that the tip discharges to form a path.

[0056] Furthermore, the ionization plate 1 and the ionization frame 2 are provided with high voltages of opposite polarities. When working, the ionization plate 1 and the ionization frame 2 are respectively connected to opposite high voltages. After power is turned on, a high voltage electric field is formed between the plates, and the discharge tip 101 ionizes the surrounding air to generate positive and negative ions, which are adsorbed on the grease particles to become charged particles.

[0057] In a preferred example, the ionization plate 1 is a square plate, and baffles 103 perpendicular to the plate surface and facing upward are integrated on the three edges of the ionization plate 1. Figures 1 to 2 As shown, the front left and right sides of the ionization plate 1 are all bent into a vertically upward baffle 103, which is installed to cover the concave edge of the cabinet 7 of the range hood to form a relatively closed cavity. On the one hand, it is used to block the oil smoke in the smoke collecting chamber 10 so that it can only reach the cabinet 7 through the grease adsorption module. On the other hand, it guides the grease flowing out of the cabinet 7 to be discharged along the ionization plate 1.

[0058] In a preferred example, the ionization plate 1 is a square plate, and one edge of the ionization plate 1 is integrated with an oil drain port 104. The oil drain port 104 can be used to drain the grease adsorbed on the ionization plate 1.

[0059] In a preferred example, the ionization zone support 3 is provided with a first row of oil grooves 301 to discharge the grease adsorbed on the ionization zone support 3. Figure 2 As shown, the rear end of the ionization zone bracket 3 is provided with a first row of oil grooves 301 which are fitted on the upper end to mount the ionization frame 2, so as to allow the captured grease to be discharged from the grease adsorption module more smoothly, reduce the risk of clogging and scaling, and ensure continuous operation and reduce cleaning.

[0060] In another embodiment of the present application, the grease adsorption module provided in the embodiment of the present application also includes a collection area component, which is arranged in the range hood and above the ionization area component, including a collection area bracket 6, a collection plate 4 and a collection rack 5, the collection area bracket 6 is provided with a second accommodating groove, the collection plate 4 is arranged in the second accommodating groove, and several rows of first low-voltage conductive rods 401 are arranged on the collection plate 4, the first low-voltage conductive rods 401 are integrated on the collection plate 4 and are integrally arranged with the collection plate 4, the collection rack 5 is arranged in the second accommodating groove, and the cover is arranged on the collection plate 4, the collection rack 5 is provided with a second low-voltage conductive rod 501 vertically connected to the first low-voltage conductive rod 401, the second low-voltage conductive rod 501 can electrically connect several rows of first low-voltage conductive rods 401, and the second low-voltage conductive rod 501 is integrated on the collection rack 5 and is integrally arranged with the collection rack 5.

[0061] like Figures 3 to 4 As shown, similar to the ionization zone, the collection zone is also composed of a bracket, a collection plate 4 and a collection frame 5. In this embodiment, the shape and size of the collection frame 5 are exactly the same as those of the above-mentioned ionization frame 2. Both are formed by stamping and bending to form square plates and square holes, which can reduce molds and save production costs. The collection plate 4 and the collection frame 5 are the same in size except for the different bending positions of the openings. Similarly, the first low-voltage conductive rod 401 and the second low-voltage conductive rod 501 serve as connecting rods to conduct electricity to each plate, and also become static filters to intercept oil smoke.

[0062] The collection area bracket 6 is made of insulating material, and the end surface is provided with a groove to embed the collection plate 4 and the collection frame 5 for installation. After assembly, the pole plates of the collection plate 4 and the collection frame 5 are staggered parallel to each other, and the distance between them is equal to form a collection area. Similarly, the first low-voltage conductive rod 401 and the second low-voltage conductive rod 501 are also staggered in the width direction of the smoke machine, resulting in each inlet of the collection area being between two square outlets, thereby strengthening the flow of smoke through the collection area and improving the capture efficiency. During operation, the two collection plates 4 are respectively connected to opposite low-voltage electricity, and a low-voltage electric field is formed between the pole plates after power is turned on. When charged grease particles pass through the collection area, they are attracted and adsorbed by the pole plates of opposite electrical polarity.

[0063] In a preferred example, a second row of oil grooves 601 is provided on the collection area bracket 6 to discharge the grease adsorbed on the collection area bracket 6 .

[0064] Furthermore, the ionization zone assembly and the collection zone assembly are connected through the edges of the ionization zone bracket 3 and the collection zone bracket 6 .

[0065] The embodiment of the present application also provides a range hood, including a cabinet 7, a smoke exhaust hood 8, a fan 9, a smoke collecting chamber 10 and the above-mentioned grease adsorption module, wherein the smoke exhaust hood 8 is arranged on the top of the cabinet 7 for exhausting smoke, the fan 9 is arranged in the cabinet 7, and the smoke collecting chamber 10 is arranged near the bottom of the cabinet 7, the grease adsorption module is arranged in the cabinet 7 and connected to the cabinet panel of the cabinet 7, and is located between the fan 9 and the smoke collecting chamber 10, and the grease adsorption module is inclined relative to the horizontal direction of the cabinet 7. When the range hood is started, the fan 9 is started to suck in oil smoke from the air inlet of the smoke collecting chamber 10, and the grease is adsorbed and discharged from the cabinet 7 under the action of the grease adsorption module, and the smoke is discharged from the smoke exhaust hood 8.

[0066] Furthermore, the above-mentioned fan 9 includes necessary components such as a fan motor 901, an impeller 902, and a volute 903, and other components are not shown in the embodiment of the present application.

[0067] Specifically, Figures 7 to 8 As shown, the grease adsorption module is installed at the connection between the cabinet 7 and the smoke collecting chamber 10, and is tilted relative to the horizontal direction. On the one hand, the inlet is more directly facing the direction of the oil smoke in the smoke collecting chamber 10, and at the same time, the outlet of the grease adsorption module is more directly facing the back plate of the cabinet 7 and the main air inlet of the fan 9, so that the oil smoke flow resistance is smaller. In addition, since the grease adsorption module is tilted, the grease above the ionization plate 1 will flow to the oil drain port 104 under the action of gravity. The bottom of the smoke collecting chamber 10 is tilted in the same direction as the ionization plate 1, and both are higher than the end near the back of the range hood. This is to allow the grease to eventually flow and gather in the oil cup 12 near the bottom of the back of the range hood.

[0068] The working principle of the range hood provided in this embodiment is as follows: the fan motor 901 is started and energized to the grease adsorption module. Under the suction of the fan 9, the oil smoke outside the range hood enters the smoke collecting chamber 10 from the smoke inlet, during which a small portion of the grease is intercepted by the filter 11. And due to the blocking of the baffle 103 and the outer wall of the cabinet 7, the oil smoke is guided to enter the grease adsorption module from the inlet of the ionization plate 1. In the ionization zone, the discharge tip 101 ionizes the surrounding air to produce positive and negative ions, which are adsorbed on the grease particles to become charged particles. After entering the collection area, most of the charged grease particles are adsorbed and captured by the plates of opposite polarity in the electric field formed by the baffle 103, preventing grease from entering the fan 9 and contaminating the impeller 902 and the volute 903, thereby protecting the cleaning and output performance of the rear-end fan 9. At the same time, the remaining smoke is discharged to the outside by the fan 9. In addition, a small portion of the oil smoke entering the oil adsorption module is intercepted by the inertia of the conductive rod, and the adsorbed and intercepted oil will be gathered along the electrode plate and the conductive rod at the rear end of the ionization area bracket 3 and the collection area bracket 6 under the action of gravity, and discharged from the first row of oil grooves 301 and the second row of oil grooves 601 at the rear end to the outer wall of the bracket and the upper surface of the ionization plate 1. At the same time, the oil on the inner wall of the cabinet 7 and the upper surface of the ionization plate 1 will be guided to flow to the oil drain port 104 for discharge, and finally gathered in the oil cup 12.

[0069] According to the grease adsorption module provided in the embodiment of the present application, the ionization plate and the collection plate are all integrally formed, and the conductive rod and the discharge tip are formed by bending the material on the plate, which saves materials, makes the entire grease adsorption module structure simple, reduces the number of components, makes assembly more convenient, and greatly reduces installation troubles. In addition to the connection and conduction function, the conductive rod can also serve as a static filter to intercept some grease, and the oil fume separation efficiency can be higher when the density of the plate distribution is the same.

[0070] In addition, the range hood provided in the embodiment of the present application is further provided on the basis of the above-mentioned grease adsorption module. Since the above-mentioned grease adsorption module is adopted, it has all the technical effects of the above-mentioned grease adsorption module. Compared with the range hood before the improvement, the range hood provided in the embodiment of the present application has a stronger oil mist interception capability, and the installation between the internal components is more coordinated and adapted.
