As shown in FIG. 4, when the main body 42 is carried on the lower case 43, the lower case engagement portion 57 has a recess 52 in the main body main portion 42 and an upper end surface of the lower case engagement portion 57. It is formed to have the same height.
[0024]
The lid body 44 is a member for covering the rotary cleaning body 59 from the front surface to the top surface, and the outer surface 66 of the lid body 44 is formed with a curved surface that is continuous with the outer surface 51 of the case main body 46. Cleaning and replacement of the rotary cleaning body 59 is performed by removing the lid body 44 from the main body main part 42. As shown in FIG. 5, guide members 67 are formed at the left and right rear ends of the lid 44 so as to extend in the horizontal rear direction. An insertion hole 68 through which the first engagement protrusion 55 of the fixing member 45 is inserted is formed at the front end portion of the guide member 67, and the first engagement protrusion 55 is attached to the guide surface of the guide member 67 upward. An elastic piece 69 is provided. Further, a guide hole 71 for guiding a guide projection 70 described later of the fixing member 45 is formed at a side end portion of the guide member 67, and a head 72 of the guide projection 70 is inserted into the guide hole 71. The head insertion hole 73 and the slide hole 75 in which the neck 74 of the guide projection 70 is slid are formed.
[0025]
As shown in FIGS. 6 and 7, the fixing member 45 is formed by a curved surface having an upper surface 77 constituting an outer surface continuous with the outer surface 51 of the case main body 46, and a side surface is a rear side wall surface 60 of the lower case 43. And a continuous surface. The fixing member 45 is slightly inward of the first engagement protrusion 55 formed at the front end portion, the second engagement protrusion 62 formed at the inner lower end portion, and the first engagement protrusion 55 slightly in front ( And a guide projection 70 extending downward. Both the first engagement protrusion 55 and the second engagement protrusion 62 are formed so as to protrude substantially in the horizontal direction, and are formed at substantially the same position (the same distance from the side wall surface) when viewed from the front. Different heights are used. The guide protrusion 70 includes a base portion 80 extending in the horizontal direction inside the fixing member 45, a neck portion 74 formed at a lower portion of the base portion 80 and having a thin width when viewed from the front, and extending downward, and a tip of the neck portion 74. And a head 72 having a thickness substantially the same width as the base.
[0026]
Next, a method of fixing the main body main part 42, the lower case 43, and the lid 44 using the fixing member 45 will be described. First, after the rotary cleaning body 59 is installed in the main body main part 42, the main body main part 42 is stored in the recess of the lower case 43. Thereafter, the lid body 44 is stacked on the upper surface of the main body main portion 42, and the main body main portion 42, the lower case 43, and the lid body 44 are overlapped. Since the main body main part 42, the lower case 43, and the lid body 44 are assembled by being laminated, they are structured to be easily separated in the vertical direction. The fixing member 45 is attached in the horizontal direction from the rear to the suction port main body 40 in which the main body main part 42, the lower case 43, and the lid 44 are stacked.
[0027]
First, the first engagement protrusion 55 of the fixing member 45 is carried to the guide member 67 of the lid body 44, and the head 72 of the guide protrusion 70 is inserted into the head insertion hole 73 of the guide member 67, and then the neck portion of the guide protrusion 70. 74 is slid forward along the slide hole 75. When the guide protrusion 70 is slid forward by the slide hole 75, the first engagement protrusion 55 is inserted into the insertion hole 68, and the elastic piece 69 engages the first engagement protrusion 55 and is inserted into the insertion hole 68. The distal end portion of the first engaging protrusion 55 thus engaged is engaged with the main body engaging hole 56.
[0028]
FIG. 8 is a perspective view showing the engagement relationship between the fixing member 45 and the lid body 44 from the back side of the lid body 44, and reference numeral 81 denotes the first engagement protrusion 55 inserted through the insertion hole 68. This is a distal end portion, and the distal end portion 81 engages with the main body engaging hole 56 of the main body main portion 42. Reference numeral 72 denotes a head of the guide projection 70, and the head 72 of the fixing member 45 inserted through the head insertion hole 73 is slid along the slide hole 75 as shown in FIG. As the head 72 slides along the slide hole 75 in this way, the fixing member 45 is engaged with the lid 44 so as not to be separated in the vertical direction.
[0029]
Further, when the first engagement protrusion 55 of the fixing member 45 is guided to the insertion hole 68 by the guide member 67, the second engagement protrusion 62 also moves in the same direction, so as shown in FIG. The second engaging protrusion 62 engages with the lower case engaging hole 63 formed in the lower case engaging portion 57 at the same time when the mating protrusion 55 engages with the main body engaging hole 56.
[0030]
In this way, with respect to the suction inlet main body 40 in which the main body main part 42, the lower case 43, and the lid 44 are stacked, the main body 42, the lower case 43, and the lid 44 are engaged with each other from the horizontal direction. Since the member 45 is provided, the fixing member 45 can prevent the main body main portion 42, the lower case 43, and the lid body 44 from being disassembled in the vertical direction, and the fixing member 45 can prevent the main body main portion 42, the lower case from being disassembled. 43 and the lid 44 can be fixed at the same time.
[0031]
Further, by using the fixing member 45, it is possible to fix the main body main part 42, the lower case 43, and the lid body 44 without using a screw member or the like as in the prior art, so that it is possible to reduce assembly labor. It becomes. further. Since it is not necessary to form a screw groove or the like for the main body main part 42, the lower case 43, and the lid 44, it becomes easy to simplify the shape and structure of each case, and to reduce the size of the suction port body 36. It becomes easy.
[0032]
As mentioned above, although the vacuum cleaner 30 which concerns on this invention was demonstrated using drawing, the vacuum cleaner 30 which concerns on this invention is not limited to what was demonstrated in embodiment of invention. For example, in the embodiment of the invention, the example in which the fixing member 45 is provided on each of the left and right sides of the suction port body 40 (two in total) has been described, but the fixing member 45 does not necessarily have to be two, There may be one or three or more. Furthermore, the fixing member 45 is not limited to the one installed at the left and right ends of the suction inlet body 40, and the fixing member 45 can attach three cases of the main body main part 42, the lower case 43, and the lid body 44. If possible, you may attach to the center part of the suction inlet main body 40, etc.
[0033]
【The invention's effect】
The suction port body according to the present invention includes a fixing member that engages the main body main portion, the lower case, and the lid body from the horizontal direction with respect to the suction port body in which the main body main portion, the lower case, and the lid body are stacked. Since it is provided, it is possible to prevent the main body, the lower case, and the lid from being disassembled in the vertical direction by the fixing member, and the three cases of the main body, the lower case, and the lid can be simultaneously removed by the fixing member. Can be fixed.
[0034]
Further, by using the fixing member, it is possible to fix the main body main part, the lower case, and the lid body without using a screw member or the like as in the prior art, so that it is possible to reduce assembly labor. further. Since it is not necessary to form screw grooves on the main body, lower case, and lid, it is easy to simplify the shape and structure of each case, and it is easy to reduce the size of the suction port Become.
