Suction Port Body For Electric Vacuum Cleaner, And Electric Vacuum Cleaner

Abstract

The present invention has an object to achieve a suction port body for an electric vacuum cleaner, which can be downsized while including a light source, and an electric vacuum cleaner including the suction port body. The suction port body (100) includes: a case body (110) having a curve-shaped portion (126) being curved so as to protrude upward and a suction port (120) in a bottom surface; a pipe portion (150) that is provided at rear of the curve-shaped portion (126) and is configured to allow communication between a suction source and the suction port (120); and a light source (210) arranged so as to radiate light to a front side of the case body (110). The light source (210) is located in front of the pipe portion (150) and at rear of a top portion of the curve-shaped portion (126).

What is claimed is: 
     
         1 . A suction port body for an electric vacuum cleaner, comprising:
 a case body having a curve-shaped portion being curved so as to protrude upward and a suction port in a bottom surface;   a pipe portion that is provided at rear of the curve-shaped portion and is configured to allow communication between a suction source and the suction port; and   a light source arranged so as to radiate light to a front side of the case body,   wherein the light source is located in front of the pipe portion and at rear of a top portion of the curve-shaped portion.   
     
     
         2 . The suction port body for an electric vacuum cleaner according to  claim 1 ,
 wherein the case body comprises:
 a main body case that has the suction port and defines a suction space; and 
 a covering case covering at least a part of the main body case, and 
   wherein the light source is arranged between the main body case and the covering case.   
     
     
         3 . The suction port body for an electric vacuum cleaner according to  claim 2 , further comprising:
 the suction space; and   a communicating portion that is provided at rear of the suction space and is configured to allow communication between the suction space and the pipe portion,   wherein the light source is arranged above the suction space.   
     
     
         4 . The suction port body for an electric vacuum cleaner according to  claim 1 ,
 wherein the case body includes a base portion at rear of the top portion of the curve-shaped portion, and   wherein, when a light-emitting unit including the light source is arranged on the base portion, an optical axis of the light source is inclined so as to extend toward the bottom surface.   
     
     
         5 . The suction port body for an electric vacuum cleaner according to  claim 1 ,
 wherein the case body includes a base portion at rear of the top portion of the curve-shaped portion, and   wherein the base portion is arranged at a position lower than the top portion.   
     
     
         6 . The suction port body for an electric vacuum cleaner according to  claim 1 , further comprising a light-emitting unit including:
 a cover that allows transmission of light emitted from the light source; and   a guide portion configured to guide the light emitted from the light source to the cover,   wherein the light-emitting unit is fixed to the case body while the guide portion is interposed between a board on which the light source is arranged and the cover.   
     
     
         7 . The suction port body for an electric vacuum cleaner according to  claim 5 , wherein the guide portion and the board are fixed to each other through intermediation of an engagement structure. 
     
     
         8 . The suction port body for an electric vacuum cleaner according to  claim 2 , further comprising:
 a rotary cleaning body provided rotatably in the suction space;   a drive unit serving as a drive source for the rotary cleaning body; and   a power transmission mechanism configured to transmit a drive force from the drive unit to the rotary cleaning body,   wherein the covering case covers the power transmission mechanism.   
     
     
         9 . The suction port body for an electric vacuum cleaner according to  claim 1 ,
 wherein the case body includes a transmitting portion having translucency, and   wherein light emitted from the light source is transmitted through the transmitting portion.   
     
     
         10 . The suction port body for an electric vacuum cleaner according to  claim 1 , further comprising:
 a rotary cleaning body provided rotatably inside the case body;   a drive unit serving as a drive source for the rotary cleaning body; and   a power transmission mechanism configured to transmit a drive force from the drive unit to the rotary cleaning body,   wherein the drive unit is arranged above and diagonally behind the rotary cleaning body.   
     
     
         11 . An electric vacuum cleaner comprising the suction port body of  claim 1 .
