The rotary brush 72 connected to the driving force transmission member 80 is treated as a rotary brush unit 90 integrated with both (see fig. 10). As shown in fig. 8 to 10, the rotary brush unit 90 is disposed between the middle housing 13 and the lower housing 12 in a state where the rotary brush 72 is detachably attached to the dust collection opening portion 74 of the lower housing 12.
< decomposition and washing of suction inlet body >
The suction port body 5 configured as described above is used for cleaning a surface to be cleaned by attaching each component to a predetermined position and connecting the component to the cleaner main body 2 of the electric cleaner 1 through the hose 3 and the extension pipe 4 in a state shown in fig. 7 and 8. After several uses, the suction port body 5 is cleaned, and particularly, when it is necessary to wash the inside with water, the cleaning is decomposed and washed with water as follows.
The user first removes the suction port body 5 from the extension pipe 4 of the electric vacuum cleaner 1 and reverses it as shown in fig. 8. Next, as shown in fig. 9, the lower casing 12 is detached from the suction port body 5. Thereafter, as shown in fig. 10, the rotary brush unit 90 is detached from the middle housing 13, and next, as shown in fig. 11, the middle housing 13 is detached from the remaining suction port body 5.
And, the user washes the detached lower case 12, the rotary brush unit 90, and the middle case 13 with water. At the time of washing with water, there is a fear that: in the interior of the housing 80a constituting the driving force transmission member 80 of the rotary brush unit 90, water enters from the portion of the driven fan 80b provided in an open shape. In this case, the entered water can be drained from the drainage hole 80c of the housing 80 a.
In cleaning the inner surface of the upper casing 11 from which the lower casing 12, the rotary brush unit 90, and the middle casing 13 have been detached, it is not particularly necessary to pay attention to the fact that almost no dust or fibrous dust flowing into the dust collecting chamber from the dust collecting opening 74 of the lower casing 12 is brought into contact with the inner surface of the upper casing 11 and is sucked into the suction port body 6. This is because, in the suction port body 5, as described above, the rotary brush 72 is disposed between the middle casing 13 and the lower casing 12 in a state of being detachably attached to the dust collection opening portion 74 of the lower casing 12, and the middle casing 13 has a substantially semi-cylindrical shape similar to the upper casing 11 and has the suction port portion 13a communicating with the suction port portion 61a of the suction port body 6. Thus, by detaching only the middle case 13 from the upper case 11, it is possible to easily wash with water.
However, when cleaning of the inner surface of the upper case 11 is attempted, the inner surface of the upper case 11 shown in fig. 11, from which the lower case 12, the rotary brush unit 90, and the middle case 13 have been taken out, may be wiped with a rag, a paper towel, or the like.
< effects of suction opening body >
The suction port body 5 of the electric vacuum cleaner 1 according to the first embodiment configured as described above is provided with the dust collecting unit 7 and the suction port body 6 having electric components such as the motor M and the circuit board N in a separated manner, and is detachably attached to the upper housing 11, the housing 13, and the lower housing 12, and the dust collecting rotary brush 72 is detachably attached to the dust collecting opening 74 of the lower housing 12.
Therefore, according to the suction port body 5, the middle case 13 and the lower case 12, which are components of the dust collecting unit 7, can be detached from the upper case 11, and the rotary brush 72 can be detached from the middle case 13 and the lower case 12. As a result, the middle case 13, the lower case 12, and the rotary brush 72, which are detached, can be washed with water without worrying about electrical components such as the motor M, and the suction port body 5 can be stored in a sanitary state of the dust collecting unit 7.
The suction port body 5 is formed such that the entire middle case 13 is transparent, a left-right long raised portion 13b is provided at the center of the upper portion of the middle case 13, and the raised portion 13b is detachably attached to the upper opening 11a of the upper case 11 in a state of being exposed upward.
Therefore, according to the vacuum cleaner body 2 in which the suction port body 5 is connected to the electric vacuum cleaner 1 through the hose 3 and the extension pipe 4, after a plurality of uses, the user can easily determine whether or not cleaning of the dirty suction port body 5 is necessary, particularly washing of the rotary brush 72 in the interior, by visually observing the interior of the middle housing 13 through the transparent raised portion 13 b. Further, the user can detach the middle housing 13 and the rotary brush 72 without touching the dirty rotary brush 72 by pressing the protruding portion 13b in a direction to lower the housing 12 with a hand.
(constitution of the rotating Brush Unit)
Next, the structure of the rotary brush unit 90, particularly the structure of the driving force transmission member 80, will be described based on fig. 12 to 15.
The housing 80a of the driving force transmission member 80 of the rotary brush unit 90 has a box shape with a substantially oval side surface, and is formed by an inner housing 80a on the side close to the rotary brush 721And an outer housing portion 80a on the side remote from the rotary brush 722And (4) forming. Inner housing part 80a1The thickness of the belt 80f is set so that the peripheral wall covers the fixed portion of the belt 80f and the belt 80f in the pulleys 80d and 80 e. Outer housing part 80a2The inner casing 80a is fixed by a fixing screw 80g while holding the rotation shaft of the pulleys 80d and 80e1And an outer housing part 80a2。
Further, when the belt 80f is loosened due to deterioration of the belt 80f, the belt passes through the inner case 80a1Contact with the belt 80f to cause the inner housing part 80a to move1If the inner surface of the housing is abraded and the replacement is necessary, the entire driving force transmitting member 80 is not replaced and only the inner housing 80a is replaced1It suffices that maintenance of the driving force transmission member 80 can be easily performed.
(second embodiment)
Although not shown in the drawing, the electric vacuum cleaner of the second embodiment having the suction port body for the electric vacuum cleaner is a so-called upright type electric vacuum cleaner in which the dust collection system is a cyclonic type and which is placed upright when stored. The suction port body 5 connected to the cleaner body of the electric vacuum cleaner of the second embodiment through the hose and the extension pipe is the same as the suction port body of the electric vacuum cleaner 1 of the first embodiment.
