JP4874730B2 - Blower with ring for protection - Google Patents

Description

  The present invention relates to a blower provided with an annular ring for protection used for agricultural and livestock ventilation and / or diffusion.

  Conventionally, in this type of blower that is relatively small and is used for the purpose of blowing and / or spreading for farming and livestock, the bell mouth is located outside the casing (wind tunnel). In addition, the outer peripheral surface becomes a sharp part. This sharp part of the outer peripheral surface is known to be very dangerous as it is, and countermeasures are taken. For example, the outer peripheral surface is bent by a winding drawing, the sharp part of the outer peripheral surface is concealed (the sharp part is eliminated), or the outer peripheral surface is bent inward of the casing to conceal the sharp part of the outer peripheral surface. A configuration such as this is adopted. However, this configuration has advantages and disadvantages, and there is a demand for a bell mouth structure that can secure safety and a bell mouth structure that can secure air volume with a simple structure.

  Prior art documents that can meet the above-mentioned demands have been investigated. The inventions and devices that are specifically relevant to the present invention, including this field, can be searched including other fields of the entire fan (a range of technologies and (Or search in this field). Thus, some somewhat relevant inventions are listed in the literature.

  Document (1) is “Outdoor unit of air conditioner” disclosed in Japanese Patent Laid-Open No. 5-87366. The present invention includes a bell mouth, which has a ridge facing outward. Therefore, since this bell mouth is configured to be installed in the main body base, there is no problem after installation. However, it may be a problem at a predetermined time such as when parts are conveyed or assembled. Therefore, the countermeasure is demanded.

Further, Document (2) is “Embedded ceiling air conditioner” disclosed in Japanese Patent Laid-Open No. 2000-227233. Although this invention is provided with a bell mouth, this bell mouth is not clear, but is considered to be the same processing as the conventional one. Therefore, in the present invention, the fan guard is provided inside the bell mouth and the case main body is provided outside the bell mouth, and the bell mouth is guarded by another member, and there is no problem after the installation. However, in the processed part of the present invention, it may be a problem at a predetermined time such as during conveyance or assembly. Therefore, the countermeasure is demanded.
