Abstract

The present invention relates to a hood device comprising: a hood cell unit that simultaneously performs air intake through a plurality of air intake cells formed without spacing in a two-dimensional array, wherein each of the plurality of air intake cells is formed in a hollow shape with both ends open and configured such that the cross-sectional area decreases from the hood intake port to the hood exhaust port; and an air exhaust pipe comprising an air delivery space formed by grouping the hood exhaust ports of each of the plurality of air intake cells into rows or columns of the two-dimensional array and interconnecting them.

  1. A hood cell unit configured to simultaneously perform air intake through a plurality of air intake cells formed without spacing in a two-dimensional array, wherein each of the plurality of air intake cells is formed in a hollow shape with both ends open and the cross-sectional area decreases from the hood intake port to the hood exhaust port; and The hood outlets of each of the plurality of air intake cells are grouped and interconnected in a row or column unit of the two-dimensional array to form an air transfer space, and the height of the air transfer space and the hood cell unit are the same, and the width of the air transfer space and the hood cell unit are different, and the air discharge pipe is included. The above hood cell unit is Each of the plurality of air intake cells is configured such that the cross-sectional area decreases at an angle between 45° and 55° from the hood intake to the hood exhaust. The above air exhaust pipe A hood device characterized by forming an air delivery space by connecting the hood outlets in a row or column along a two-dimensional array of the plurality of air intake cells so that air is delivered in one direction, and combining a duct unit that discharges air in the center to generate airflow by distributing pressure and air volume to each of the plurality of air intake cells.
  2. In paragraph 1, the air transfer space is A hood device characterized by increasing the volume by adjusting the width as it moves toward the direction of the above-mentioned duct unit to form an air flow.

Description

Hood Device The present invention relates to a hood device, and more specifically, to a hood device having an improved structure capable of efficiently exhausting cooking fumes generated by a heat source during a cooking process and protecting the breathing area of a worker. Kitchen effluent refers to cooking fumes, which consist of oil vapors generated during high-temperature cooking processes, as well as harmful substances and fine particles contained therein. Cooking fumes are produced during frying, stir-frying, and grilling, where oil is dispersed in aerosol form, along with combustion byproducts, gaseous organic pollutants, and steam emitted by food ingredients. Cooking fumes contain solid ultrafine particles with a diameter of 100 nm or less that cannot be filtered out by the respiratory system; these particles penetrate directly into the lungs and bloodstream, destroying cells and organs within the body, and are therefore classified as carcinogens. As such, indoor air pollution caused by cooking fumes generated during the cooking process must be removed because it not only causes foul odors but also has adverse effects on the human body. Generally, the method used to remove cooking fumes involves forcibly exhausting them to the outside through an exhaust hood. However, if the capacity of the exhaust fan is insufficient, the hood's performance deteriorates, causing pollutants to stagnate indoors and accumulate in the respiratory systems and bodies of indoor workers, which can threaten their health. Additionally, there is a problem that noise may occur due to motor overload. Therefore, there was a need to develop a kitchen hood structure capable of securing a uniform airflow velocity and minimizing noise issues to ensure stable cooking fume exhaust. FIG. 1 is a side view showing a kitchen hood device according to one embodiment of the present invention. FIG. 2 is a perspective view showing the kitchen hood device of FIG. 1. Figure 3 is a plan view showing the kitchen hood device of Figure 1. Figure 4 is a bottom view showing the kitchen hood device of Figure 1. FIG. 5 is a drawing illustrating the arrangement of a kitchen hood device according to the present invention. FIG. 6 is a drawing showing the results of a performance test of a kitchen hood device according to the present invention. The description of the present invention is merely an example for structural or functional explanation, and therefore the scope of the present invention should not be interpreted as being limited by the examples described in the text. That is, since the examples are subject to various modifications and may take various forms, the scope of the present invention should be understood to include equivalents capable of realizing the technical concept. Furthermore, the objectives or effects presented in the present invention do not imply that a specific example must include all of them or only such effects; therefore, the scope of the present invention should not be understood as being limited by them. Meanwhile, the meaning of the terms described in this application should be understood as follows. Terms such as "first," "second," etc., are intended to distinguish one component from another, and the scope of rights shall not be limited by these terms. For example, the first component may be named the second component, and similarly, the second component may be named the first component. When it is stated that one component is "connected" to another component, it should be understood that it may be directly connected to that other component, or that there may be other components in between. Conversely, when it is stated that one component is "directly connected" to another component, it should be understood that there are no other components in between. Meanwhile, other expressions describing the relationships between components, such as "between" and "exactly between," or "adjacent to" and "directly adjacent to," should be interpreted in the same way. A singular expression should be understood to include a plural expression unless the context clearly indicates otherwise, and terms such as "include" or "have" are intended to specify the existence of the implemented features, numbers, steps, actions, components, parts, or combinations thereof, and should be understood not to preclude the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. In each step, identifiers (e.g., a, b, c, etc.) are used for convenience of explanation and do not describe the order of the steps; the steps may occur differently from the specified order unless a specific order is clearly indicated in the context. That is, the steps may occur in the same order as specified, may be performed substantially simultaneously, or may be performed in the reverse order. Unless otherwise defined, all terms used herein have the same meaning as generally understood by those skilled in the art to
