Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a charging stand for a floor-moving vacuum cleaner.

BACKGROUND TECHNOLOGY Conventionally, many small vacuum cleaners such as the Birdy type were rechargeable, requiring no power cord, for convenience in cleaning operations. That is, as shown in Fig. 8, a storage battery 2 is built into the vacuum cleaner body 1, and the electric power is used to drive a fan motor 3, so that the vacuum cleaner can be carried freely without being tied to a power cord or the like during cleaning. Ta. Furthermore, when the capacity of the storage battery becomes low, the vacuum cleaner is placed upright on a charging stand 4 and is supplied with electricity from a charging terminal 5 provided on the rear surface of the vacuum cleaner main body 1.

Problems that the invention aims to solve: With the above conventional configuration, when charging the vacuum cleaner, it is necessary to lift the vacuum cleaner and lower it with the rear side down from vertically above the charging stand. It was extremely easy to charge the vacuum cleaner. However, when attempting to charge a general floor-moving vacuum cleaner using this charging stand, it is necessary to lift the vacuum cleaner body each time the charging operation is performed, which requires a great deal of effort. In addition, the center of gravity of the vacuum cleaner itself tends to be located at the rear because the rear fan motor and storage battery are generally mounted thereon, and when lifted with the rear end at the bottom, the center of gravity becomes considerably lower. Therefore, the vacuum cleaner main body, whose center of gravity is at a low position, tends to swing back and forth and from side to side during charging operations, making it difficult to position the cleaner. Furthermore, when the vacuum cleaner accidentally collides with the charging stand, the impact force is large, and both the vacuum cleaner itself and the charging stand are easily damaged.

The present invention solves these problems, and aims to provide a floor-moving vacuum cleaner that allows charging work to be performed easily without much effort, and that can be positioned reliably without damaging the vacuum cleaner itself or the charging stand. purpose.

Means for Solving the Problem In order to solve this problem, the present invention is of a floor moving type, has a built-in storage battery, and has a running roller disposed at the lower end of the rear part of which partially protrudes rearward. a recess into which the vacuum cleaner is received in an upright position with the rear surface being the lower end; an inclined surface that slopes downward from the front end of the recess; and rollers of the vacuum cleaner provided on both sides of the recess. The roller receiving portion has a flat surface connected to the inclined surface, an arc-shaped stop surface connected to the rear of the flat surface and abutting the circumferential surface of the roller, and further includes a The vacuum cleaner is equipped with a charging terminal that comes into contact with a charging receiving terminal provided on the rear surface of the vacuum cleaner.

Function With this configuration, charging can be performed by moving the vacuum cleaner near and far while running it relative to the charging stand, and by rotating the roller around the recessed portion, so there is no need to lift the vacuum cleaner. Also, since there is no friction when rotating, charging can be done easily. Furthermore, positioning can be easily performed by placing the roller on the roller receiving portion.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

By the way, the storage battery 17 is stored in a storage chamber 32 that can be opened and closed by a removable lid 31 at the lower rear end of the vacuum cleaner main body 11.
It is held by ribs 33. The storage chamber 32
A contact spring 3 is in pressure contact with the terminal 34 of the storage battery 17.
5, and this contact spring 35 is connected to the fan motor 16.
It is connected with a lead wire (not shown).

The vacuum cleaner configured as above is shown in Figures 5 to 7.
The battery is charged by being placed on the charging stand 36 shown in the figure in an upright position with the rear surface facing toward the bottom. Next, the configuration of this charging stand 36 will be explained in detail. The charging stand 36 is composed of a case 37 and a bottom plate 38. The upper surface of the case 37 has a recess 39 formed to match the shape of the rear end of the vacuum cleaner main body 11, and rollers 12 for running the vacuum cleaner main body 11 are placed on both sides of this recess 39. Roller receiving part 4
0 is formed. Reference numeral 41 denotes an inclined surface formed on the upper surface of the case 37 so as to be inclined downward from the front end of the recess 39 to the lower end of the charging stand 36 . By the way, the roller receiving part 40 is provided with an arc-shaped stop surface 42 that comes into contact with the rear end of the roller 12 that rises to move backward on the slope surface 41, and the lower end of this stop surface 42 and the upper end of the slope surface 41 It is provided with a flat surface 43 that is continuous with. Reference numeral 44 denotes wall surfaces located on both sides of the recess 39 and the inclined surface 41. The wall surfaces 44 on both sides of the inclined surface 41 are inclined so as to widen toward the front end side, and serve as guide walls for the roller 12. Note that the charging stand 36 is equipped with a transformer 45.
and a charging control circuit board (not shown) are built in, and a power switch 46 and a charging display LED are installed on the inclined surface 41 at a position outside the passage area of the roller 12.
47 is arranged, and a power cord 48 is provided on the rear surface. A charging terminal 49 is attached to a leaf spring 50 inside the case 37, and normally projects upward from the opening 51 on the top surface of the case 37 due to the elasticity of the leaf spring 50. This charging terminal 49
is adapted to come into contact with the charging receiving terminal 25 of the vacuum cleaner main body 11 placed in an upright state in the recess 39 on the case 37. 52 is the charging stand 36
This is the same as the storage battery 17 built in the vacuum cleaner main body 11, and the contact spring 54 comes into contact with the terminal 53 of this backup battery 52, and the backup storage battery 52 is It is configured to be able to store electricity at the same time as the storage battery 17.

Using the charging stand 36 configured as described above, the vacuum cleaner main body 11
The operation of charging the storage battery 17 will be explained.

When the vacuum cleaner main body 11 is placed on the charging stand 36, the vacuum cleaner main body 11 is moved backward and the roller 12 is moved up the slope 41, and the roller 12 is moved up the above-mentioned stop as shown by the two-dot chain line in FIG. After pushing up until it contacts the surface 42, the cleaner body 11 is rotated 90 degrees around the roller 12 so that the rest portion 24 on the rear surface rests on the case 37. This results in
While the vacuum cleaner main body 11 is maintained in the upright state (solid line state in FIG. 7), the charge receiving terminal 25 is
comes into contact with the charging terminal 49 and enters a charging state. After charging is completed, the vacuum cleaner main body 11 can be moved down the inclined surface 41 by performing a reverse operation, and returned to its use position. Therefore, there is no need to lift the vacuum cleaner main body 11 during charging and when charging is completed, and it is only necessary to move the vacuum cleaner main body 11 near and far while running it with respect to the charging stand 36, and to rotate it around the rollers 12. can be done very easily.

Effects of the invention As described above, according to the invention, charging can be performed by moving the vacuum cleaner near and far while running it relative to the charging stand, and rotating it around the rollers, so there is no need to lift the vacuum cleaner itself. Since there is no friction during rotation, it greatly contributes to labor reduction. In addition, positioning of the vacuum cleaner during charging can be performed simply by placing the roller on the roller receiving portion, and work efficiency is greatly improved.
