New description: [New technical field] This creation is a part of the range hood, especially a motor casing with waterproof effect. [Prior Art] Because Chinese cooking habits are mostly frying, boiling, frying, frying, cooking _ often produces soot, so the range hood (or range hood) is the basic equipment of Taiwan's kitchen The exhaust hood is mainly provided with more than one motor on the casing, and the soot is extracted by the motor driving the blade to rotate. The motor form of the hood is as shown in the fifth figure, and the motor (3 〇) includes one. The motor casing (3]_) is provided with a coil (not shown) inside the motor casing (3丄), and the center of the coil is provided with a motor shaft (3 2 ) protruding from the bottom of the motor casing (3 1 ), thereby driving The blades rotate and produce suction. Please also refer to the sixth figure. The existing motor casing (3 1 ) includes upper and lower upper casings (3 1 0 ) and lower casings (3 1 1 ), and upper and lower casings (3 10) ( 3 11) There are several perforations (3 1 3 ) and screw holes (3 1 4 ) on the peripheral wall of the upper and lower coaxial pairs for the bolts ( 3 1 5 ) to pass through the perforations from top to bottom (3 1 3 ) and screwed onto the screw hole (3 1 4 ). However, since the range hood often sucks the soot, it is easy to leave oil on the inner peripheral wall of the casing and the motor surface, and it is difficult to clean. Therefore, the manufacturer designs an automatic washing range hood to automatically clean the inside of the range hood, and water spray When the circular outer peripheral surface of the upper and lower shells (310) (311) flows downward due to gravity, it is less likely to flow in between the upper and lower shells (3 ι〇) (31 4 M293404 1 ), but The upper shell (3丄) is provided with a perforation (3 1 0) communicating with the top surface, so that the bolt (3 15) is screwed from top to bottom, so the water will be perforated by the opening upward (3 1 3 ) Inflow, constantly accumulating in the accumulation, due to, can not be removed, so it will slowly penetrate between the bolt (3 i 5) and the perforation (3 1 3), and then the upper and lower shells (3 work) (3) Sticking each other 5 far into the inside, causing the coil to be damaged by moisture. Therefore, the structure of the existing motor casing is necessary to be improved. 0 [New content] In order to improve the above-mentioned defects, the main purpose of this creation is to provide a Avoid water flowing into the waterproof motor casing of the motor casing. For the above purposes, this The main design concept of the creation is to sing the top surface of the motor casing to make the water unable to flow into the interior. The above σ. The specific technical content of the ten concept includes one upper and lower casing, the lower shell 'and the number The support is coupled to the bolt between the upper and lower shells, and the upper shell and the lower shell are attached to each other. The surface is defined as a joint surface, and the inner and lower shells respectively have a receiving groove communicating with the joint surface, wherein the lower shell The peripheral wall of the upper casing is provided with a through hole communicating with the joint surface and the bottom portion, and the peripheral wall of the upper shell is provided with a screw hole coaxially corresponding to each of the through holes, each screw hole is connected to the joint surface, and the screw hole is located at the top of the upper shell. The bolt is threaded into the perforation and screwed into the screw hole of the upper casing. After implementing the above technical means, the specific benefit obtained by the creation is due to the screw hole of the upper shell of the creation. Opening downwards, that is, the top surface of the upper shell is closed. Even when cleaning, water is sprayed from the bottom of the perforated bottom of the lower shell, and 5 M293404 will fall due to gravity, so that the existing product does not accumulate in the perforations of the upper shell. And slowly infiltrate the motor The inside of the shell can achieve the purpose of waterproofing. [Embodiment] Please refer to the first illustration. The waterproof motor casing of the range hood provided by this creation still includes the upper and lower upper shells (1〇) and the lower shell (1). 2 〇 The top of the peripheral wall of the upper casing (10) is provided with a plurality of radially protruding joints (1 1 ), and perforations (i 2) are provided with perforations (丄丄〇) for bolts to pass through and fix On the casing of the range hood, the upper and lower shells (1 〇) (20) are fitted to each other as the joint surface (丄〇〇) (200), upper and lower shells (1) 〇) (2〇) respectively have a pocket (12) (22) connected to the joint surface (100) (200) to accommodate the motor coil, the lower shell (20), and the U" low-slung perimeter wall center And there is a perforation <heart tooth q 2 3 ) communicating with the trough (22) for the motor shaft to pass through the water will flow into the inside of the casing, and there are several perforations in the interval (2 4 lower shells (2 0) The joint surface (2' is used to prevent the cleaning of the range hood, especially for the peripheral wall of the lower casing (20).] Each perforation (24) is connected to 0 0) and the bottom. The upper shell (10) is provided with a plurality of screw holes (14) coaxially with the wearer L (23), and the screw holes (14) communicate with the joint surface (丄〇〇) and extend Inside the inner wall of the upper casing (10), the end is provided with a plurality of bolts (25) for being inserted into the perforations from the bottom up L*μ and screwed into the screw holes (; L 4 ), 20) Combine together.
