Description

Technical Field

[0001] This utility model relates to the technical field of integrated fume hood machines, specifically to an integrated electrostatic fume hood machine with internal circulation. Background Technology

[0002] In fields such as kitchen fume purification and industrial waste gas treatment, integrated fume hoods are widely used due to their integrated design, which efficiently collects and purifies smoke and exhaust gas. Existing internal circulation integrated fume hoods typically have multiple built-in filters, using multi-layer filtration to intercept and purify particulate matter, oil, and other impurities in smoke and exhaust gas, ensuring the cleanliness of the discharged gas. However, in actual use, as impurities accumulate on the filters, their filtration efficiency gradually decreases, necessitating regular filter replacement. Because the integrated machine contains a large number of filters, each with a relatively independent installation location, replacement requires operators to disassemble, replace, and install each filter sequentially, resulting in a cumbersome process and significant time and labor costs. Therefore, this invention provides an internal circulation electrostatic integrated fume hood. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0026] like Figure 1 and Figure 2 As shown, an integrated electrostatic hood with internal circulation includes a base box 1 and a top box 2 connected together. The bottom of the base box 1 has an inclined structure and a first air inlet, while the top has a first air outlet. The top box 2 is located above the base box 1, with a second air inlet at the bottom communicating with the first air outlet, and a second air outlet at the top. Oil fumes enter the base box 1 through the first air inlet, exit through the first air outlet, then enter the top box 2 through the second air inlet, and finally exit through the second air outlet. The first air outlet is located near the first end of the base box 1, and the second air outlet is located near the second end of the base box 1.

[0027] A pre-filter 3 is installed at the first air inlet of the bottom box 1, and a support plate 4 is installed inside. Several centrifugal oil-slinging discs 5 are installed on the support plate 4. The centrifugal oil-slinging discs 5 are evenly distributed along the length of the bottom box 1 and are used to separate large particles in the oil fumes. The centrifugal oil-slinging discs 5 are prior art and will not be described in detail here.

[0028] The top box 2 is divided into an air inlet chamber, a filter chamber, and a fan chamber along its length. The air inlet chamber is located above the second air inlet. The top box 2 also has an opening on the side wall of the filter chamber, with a removable door 11 at the opening. The removable door 11 facilitates the replacement of the filter screen inside the filter chamber.

[0029] The air inlet chamber is used for airflow to enter the top box 2.

[0030] like Figure 3 and Figure 4 As shown, the bottom surface of the filter chamber is provided with a bottom sliding groove 6, and the top surface is provided with a top sliding groove 7 corresponding to the bottom sliding groove 6. A mounting base 8 is provided between the bottom sliding groove 6 and the top sliding groove 7, which slides in conjunction with both. The mounting base 8 includes a base 81 adapted to the bottom sliding groove 6 and a top seat 82 adapted to the top sliding groove 7. The base 81 and the top seat 82 are connected by connecting plates 83. There are four connecting plates 83, respectively located at the four corners of the base 81, and two connecting plates 83 located at the same end of the base 81 are connected by a connecting sub-plate 84 to improve the structural strength of the mounting base 8.

[0031] Both the base 81 and the top seat 82 are provided with several U-shaped mounting slots 9, and the U-shaped mounting slots 9 on the base 81 correspond one-to-one with the U-shaped mounting slots 9 on the top seat 82, for installing the filter screen. The filter screen slides within the U-shaped mounting slots 9.

[0032] like Figure 5 As shown, the first end of the U-shaped mounting groove 9 faces the door 11, and the second end is away from the door 11. A sealing plate 12 is provided at the second end to close its end. The sealing plate 12 can prevent the filter screen from sliding out of the U-shaped mounting groove 9 when it is installed in the U-shaped mounting groove 9.

[0033] Two extrusion plates 13 are installed inside the U-shaped mounting groove 9. One side of the extrusion plate 13 is connected to the inner wall of the U-shaped mounting groove 9 through an elastic element 14, and the other side extrudes the filter screen. The elastic element 14 allows the extrusion plate 14 to elastically extrude the filter screen inside the U-shaped mounting groove 9, so that the filter screen is firmly installed inside the U-shaped mounting groove 9.

[0034] Preferably, the elastic element 14 is made of silicone rubber, which has advantages such as high temperature resistance, oil resistance, and corrosion resistance, and can ensure that it has a long service life.

[0035] A fan 10 is installed inside the fan shack, and the second air outlet is located at the top of the fan shack.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
