Research on the design of the side suction kitchen hood of mechanical design 1 Feng Yi (College of Art and Design, Beijing Forestry University, Beijing 100083, China) The main design features of the V2100 side suction kitchen hood are designed for its function, shape, material and color. Optimized design and product design for related industries. The range hood is a kitchen appliance (1) that purifies the kitchen environment. The sleek, well-made hood not only creates a comfortable cooking environment, but also enhances the interior of the home kitchen. In the fierce market competition, the trend of product homogenization has become more and more obvious, and innovations that rely solely on the practical functions of products are not enough to win consumers' favor. In this case, personalization and fashion gradually become the decisive factor for consumers to buy the product. Product form is the most direct way to reflect perceptual factors, and product design has become an important competitive method for many companies. The V2100 hood is an improved design based on the original V1100 hood. By analyzing the design shortcomings of the original products and combining the market research results, the main design features of the V2100 side suction kitchen hood are determined, and the design scheme is optimized. Finally, the ease of use and shape of the side suction hood is Improved design in terms of color and material. 1 Product Model Analysis 1.1 Design Disadvantages of Original Product The V2100 range hood is an improved design of the V1100 side suction range hood. The V1100 side suction hood is a product that was put on the market a year ago. It can not meet the needs of target consumers in terms of aesthetics, ease of use and humanized design. V1100 side suction hood as shown, the shortcomings are shown in Table 1. Table 1 V1100 hood design disadvantages evaluation elements shortcomings aesthetic appearance complex material cover is cold-rolled steel sheet, surface smear treatment, aesthetic Not enough color color dim m mechanical button, operation sometimes fails, feedback is not clear, easy to accumulate gray user experience dust, not easy to clean suitability shape is not easy to integrate into the kitchen environment, installation, maintenance is not convenient 1.2 modeling design goals through market research And combined with the design goals of the enterprise, the appearance design direction of the V2100 range hood is determined: (1) the appearance adopts simple lines, reflecting the beauty and fashion; (2) the material is mainly made of stainless steel plate and glass; (3) color Light, mainly silver-gray and enamel. The hood is tilted. It has a large operating space for the user when cooking. It is not easy to bump the user's head. (5) It can be integrated with the cabinet to save kitchen space. , coordinate with the environment. 2 Modeling The target consumer of the V2100 range hood is targeted at middle- and high-income people aged 30 to 40. The group pursues quality of life and pays attention to the function and design of the product. According to market research, it is determined that the V2100 hood is a product with a high-tech appearance and a simple shape. 2.1 Main components and dimensions of the product According to market research, it is determined that the main components of the V2100 side suction range hood are two types, external and internal. The minimum installation distance from the lower edge of the range hood must be greater than 650mm, mainly to prevent the hood from catching fire and causing a safety accident. The basic dimensions of the V2100 hood are shown in Table 2. Part Name Size Total Length of the Body Total Height of the Body Maximum Cross Section Wide hood Long hood Wide hood Wide hood High exterior decorative cover Long outer cover Wide exterior decoration Cover height 2 The basic size of the V2100 range hood 2.2 Conceptual design According to the design goals and enterprise requirements of the V2100 range hood, the concept design is carried out by means of brainstorming, association, etc., and the solution is modeled by computer aided design. analysis. The outer casing of the hood is stamped from stainless steel. The shape of the hood can be straight, simple and overall. The scheme is as shown. 2.3 The qualitative evaluation of the program is reduced, and the efficiency of smoke exhaustion is affected. Scheme B: The side view of the hood is S-shaped, and the inlet is stamped and formed by a thin metal plate. The overall shape is relatively new, but the shape of the S-shaped hood may affect the exhaustion rate of the soot and reduce the exhaust efficiency. Option C: The side view of the hood is in the shape of an inverted triangle, and the inlet is formed by stamping a thin metal sheet. However, the styling is not innovative enough. It is similar to the common range hoods on the market. The overall shape is not simple enough to meet the design positioning. Option D: The overall shape is simple and generous, and the square shape design enhances the uniformity of the appearance style, and takes into account the practicality and aesthetics. The control panel is designed for easy operation and ergonomics. The overall appearance is simple, novel, easy to assemble, and low in cost. Radar map analysis is carried out on the advantages and disadvantages of the four conceptual schemes, such as aesthetics, innovation, ease of use, suitability and functionality. The comprehensive evaluation of scheme D has the highest score. As shown, further design can be carried out on this basis. 2.4 Overall design The four schemes are based on the internal parts of the original product and the original technology to improve the design. The overall length is basically controlled between 900~920mm, and the overall height is 510mm. The inlet and the hood are integrated. The part is integrated into the design, and the edge of the hood is light and thin, which can visually block the outer casing of the fan and other parts, so that the product has a light and thin visual effect. Scheme A: The cross-sectional profile of the hood is composed of two symmetrical arcs. The control panel is integrated into the surface of the hood, and the overall shape is coordinated. However, the outer curved hood surface design may cause some of the fumes to be exhausted. The rate is optimized for the details of the control panel and the inlet of the hood. In the computer-aided 3D modeling stage, using SolidWorks software, combined with imported concept sketches as modeling, 3D design of appearance and parts, and inspection by virtual assembly and virtual human-machine evaluation, the place where the overall shape is unreasonable optimization. Solid-Works software seamlessly interfaces with KeyShot rendering software to add materials, scenes, textures, textures, and more to 3D models. The rendering of the final plan rendered is as shown. The rendered hood is simple, generous and has a sophisticated technical aesthetic. The exterior part adopts a smooth glass panel as the decorative board of the smoke inlet. The control panel and the smoking port adopt the stainless steel sheet stamping process, which highlights the visual contrast effect of the material, increases the sense of science and technology, and meets the requirements of the design goal. The design details and installation scenarios are as shown. Sculptural design details using scene effects 2.5 materials and processing technology analysis V2100 hood visual quality depends on the choice of appearance materials, processing technology and surface treatment effects. The degree of sophistication of materials is an important factor influencing the consumer's visual experience. The body of the V2100 hood is made of 0.6mm thick 201 stainless steel sheet and the surface is processed by wire drawing. The brushed stainless steel produces a strong texture contrast with the glass panel of the hood, and is also easy to clean during use. Due to its styling characteristics, the control buttons are injection molded with ABS resin and the surface is plated to ensure the overall visual effect of the control buttons and the panel. 3 Conclusions Taking the V2100 side suction kitchen hood design as an example, the consumer's needs and corporate goals were analyzed, and the design requirements of the hood were determined. The design of the V2100 side suction kitchen hood has undergone the process of styling analysis, design positioning, solution creativity, solution deepening, detail design, etc., and is optimized according to the requirements of the manufacturing process. The design process not only pays attention to design aesthetics, but also focuses on materials and processing techniques. The overall design process verifies the feasibility of the appearance and structure through computer-aided design.
