[0008]
【Example】
Embodiments of the present invention will be described below with reference to FIGS.
[0009]
In FIG. 1, a vacuum cleaner 1 includes a suction tool 3 attached to one end of an extension pipe 2 and sucking dust, and a hand handle 4 connected to the other end of the extension pipe 2 at one end, and at the other end, The hose 6 includes a hose joint 5 connected to a vacuum cleaner main body (hereinafter referred to as a main body 7). The main body 7 includes one front wheel caster 8 and a pair of rear wheels 9 that are pivotally supported.
[0010]
As shown in FIG. 2, the dust collection storage portion 10 formed in the front of the main body 7 is sucked from the suction tool 3 and passes through a suction passage (not shown) in the extension pipe 2 and the hose 6. A dust collecting unit 11 that separates and collects the dust transferred up to 7 from the suction air is detachably mounted.
[0011]
In addition, an electric blower 12 and the like for generating suction air are incorporated in the main body 7 behind the dust collection storage portion 10. The suction side of the electric blower 12 communicates with an air suction portion 14 a provided on the rear wall 14 through the opening 13. The air suction portion 14 a is surrounded by an inclined seal surface 15 that comes into contact with the dust collection portion 11 when the dust collection portion 11 is attached to the dust collection storage portion 10.
[0012]
An exhaust filter 16 is provided behind the main body 7, and the exhaust from the electric blower 12 passes through the exhaust filter 16 and is released to the outside of the main body 7. Further, the main body 7 has other parts, that is, an electric system such as a control unit 17 for controlling power consumption of the electric blower 12 and a cord (not shown) for supplying power to the electric blower 12 in the main body 7. A winding device for winding a cord (not shown) or the like is incorporated.
[0013]
A front wall 18 of the main body 7 rises from a bottom wall 19, and the bottom wall 19 is a lower end surface of the dust collection storage unit 10. An air inlet 20 for detachably connecting the hose joint 5 is provided at a substantially central portion of the front wall 18. The intake port packing 21 is attached to the end surface of the intake port 20 on the dust collection storage unit 10 side, and prevents air leakage between the intake port 20 and the dust collection unit 11. Tightness is further improved by forming a lip shape on the tight surface.
[0014]
As shown in FIGS. 2 and 3, the dust collecting unit 11 includes a coarse dust storage chamber 22 that is provided at a lower portion of the dust collecting unit 11 and collects coarse dust from the dust-containing airflow that has passed through the air inlet 20. The centrifuge chamber 23 is superposed on the coarse dust storage chamber 22 and is superposed on the upper side in this embodiment, and a centrifuge chamber 23 for separating fine dust from the airflow from which coarse dust is almost removed, and the centrifuge chamber 23 Three chambers, a fine dust storage chamber 24, which is provided in parallel with the coarse dust storage chamber 22 below and accumulates fine dust centrifuged in the centrifugal separation chamber 23, are formed. The fine dust chambers 24 are partitioned and partitioned from each other. A suction port 26 is formed in the dust collection unit front wall 25 of the dust collection unit 11, and one end of the suction port 26 is concentric with the suction port 20 when the dust collection unit 11 is set in the main body 7. The other end communicates with the coarse dust chamber 22.
[0015]
The coarse dust storage chamber 22 has a dust storage chamber lid 27 having a lid packing 31 for keeping the coarse dust storage chamber 22 and the fine dust storage chamber 24 at a negative pressure. It communicates with the centrifuge chamber 23 through a primary filter 32 which is dust collecting means. The primary filter 32 plays a role of collecting coarse dust in the coarse dust storage chamber 22 among suction air including dust flowing into the coarse dust storage chamber 22, whereby the coarse dust is stored in the coarse dust storage chamber 22. It is configured to accumulate in the chamber 22.
[0016]
A packing plate 35 is fitted on the outer periphery of the lid plate 34 having the dust collecting part air suction part 33, and is detachably attached by being attached to the intake side opening of the electric blower 12 of the dust collecting part 11 without any gap. It is done. The packing 35 is in a state of being lightly pressure-bonded to the inclined seal surface 15 in a state where the dust collecting portion 11 is attached to the dust collecting housing portion 10, and prevents outside air from flowing into the air suction portion 14 a from the outside of the main body 7. Yes.
[0017]
As shown in FIGS. 4 and 5, the left and right side surfaces 42 of the dust collection portion 10 in the lower body 41 are substantially U-shaped, and a transparent side wall 44 surrounded by a soft cushioning material 43 is a separate part. It is attached. A U-shaped groove 45 is provided in the upper part of the side wall 44, and a lead wire 46 that electrically connects an electrical component such as a terminal attached to the hose joint 5 and the control unit 17 built in the main body 7 is press-fitted. It is set in a relaxed manner.
[0018]
In addition, a guide line 47 is drawn on the surface of the side wall 44, which is a guide for fullness of dust in the dust collecting portion 11. An upper body 48 is disposed above the lower body 41, and the side wall 44 is sandwiched and fixed.
[0019]
As shown in FIGS. 6 and 7, an opening / closing lid 50 provided with a rotation shaft 49 pivotally supported at the rear portion of the upper body 48 is rotatably provided above the dust collecting storage portion 10. A transparent or semi-transparent inner lid 51 is provided at a substantially central portion of the opening / closing lid 50, and when the opening / closing lid 50 is closed, the dust collection portion 11 is lightened through a soft material 52 attached to the upper portion of the dust collection portion 11. It is configured to hold down.
[0020]
Next, the operation of the above configuration will be described.
[0021]
Since the upper part of the dust collecting part 11 is completely covered with the opening / closing lid 50 and the side surface is completely covered with the side wall 44, the lower body 41 and the upper part 48, the appearance of the main body 7 can be freely set regardless of the outer shape of the dust collecting part 11. Can be designed. Further, since the inner lid 51 and the side wall 44 are made of a transparent material, the presence / absence of the dust collecting portion 11, the installation state, the dust suction state, etc. can be confirmed even when the opening / closing lid 50 is closed. is there. In addition, since a guide line 47 serving as a guide for throwing away dust from the dust collecting unit 11 is drawn on the side wall 44, the user can visually tell the dust throwing time.
[0022]
In addition, since a soft material 52 is provided at a contact portion between a part of the opening / closing lid 50 or the inner lid 51 and the upper part of the dust collecting portion 11, the dust collecting portion 11 is lightly pressed. It is possible to prevent rattling of the dust collection unit 11 during movement, and to prevent damage and breakage due to collision of the opening / closing lid 50 and the dust collection unit 11. Moreover, since the circumference | surroundings of the side wall 44 are comprised with the soft buffer material 43, the damage and damage of the transparent side wall 44 can be prevented. Furthermore, since the groove 45 for passing the lead wire 46 is provided above the side wall 44, the lead wire 46 can be easily routed.
[0023]
【The invention's effect】
According to the present invention, in a vacuum cleaner having a dust collecting storage part for storing a removable dust collecting part for collecting dust, the external appearance of the main body can be freely designed regardless of the outer shape of the dust collecting part. In addition , the lead wire can be easily routed.
