Description

[Detailed explanation of the idea] Industrial applications This proposal relates to a vacuum cleaner with a parts storage case.

Prior Art For example, in a vacuum cleaner with a parts storage box disclosed in Japanese Utility Model Application Publication No. 55-4781, when fitting the vacuum cleaner into the parts storage box, the cord reel operating body protruding outward is cleaned. Since the cord reel is rotated toward the machine and retracted, the cord reel operating body does not cause any trouble when mating. However, if the power cord that is wound up on the cord reel has a drawer outlet located at the bottom of the vacuum cleaner and below the fitting position with the parts storage box, the power cord may not be fully retracted and the vacuum cleaner may be opened. If the vacuum cleaner is placed and fitted in the parts storage box, the power cord will be caught between the vacuum cleaner and the storage box, and the vacuum cleaner must be removed from the storage box again to operate the brake operating body. There is also a risk of damage and amputation.

Problems to be Solved by the Invention This invention was made in view of the above points, and the power cord will not be damaged even if the vacuum cleaner is placed and fitted in the parts storage case with the power cord pulled out. The purpose is to ensure that the cord can be stored in the cord reel.

Means for Solving the Problems The vacuum cleaner with a parts storage case of the present invention has a drawer inlet for the power cord wound around the cord reel on one side of the main body case in which the electric blower and the cord reel are built. It consists of a vacuum cleaner with a brake operating body for the cord reel on its side, and a parts storage case in which the lower part of the vacuum cleaner is removably placed and fitted, and the drawer opening is fitted with the parts storage case. The brake operating body is provided above the fitting surface and protrudes downward and outward from the upper end of the component storage case so as to contact the fitting surface and rotate upward.

Function When the vacuum cleaner is placed and mated in the parts storage case with the power cord pulled out, the brake operating body comes into contact with the mating surface and rotates upward, which releases the brake of the cord reel and prevents the cord reel from mating. The power cord is smoothly wound onto the cord reel from the drawer inlet located above the mating surface.

Example An embodiment of the present invention shown in the drawings will be described below.

Reference numeral 1 denotes a vacuum cleaner, which includes an electric blower 2, a main body case 5 containing a cord reel 4 for a power cord 3, and a filter device 8 detachably connected to the front part of the main body case by a clamp 5 and a lower engagement part 7. The dust collecting case 9 houses the dust collecting case 9. 1
0 is a parts storage case for storing a floor suction tool, a flexible suction hose, an extension pipe, etc. (not shown), and is removably fitted to the lower part of the vacuum cleaner 1 by a pair of clamps 11, 11.

A pull-out opening 12 for the power cord 3 wound by a cord reel is provided at the rear of the main body case 5 and at the side surface above the upper end of the fitting surface with the component storage case 10, and on the substantially opposite side thereof. A brake operating mechanism 13 for the cord reel 4 is provided below the upper end of the fitting surface with the parts storage case 10.

The brake operating mechanism 13 includes a brake drum 14 formed on the outer periphery of the cord reel 4, a roller receiving portion 16 having a wedge-shaped receiving surface 15 formed in a concave portion in the main body case 5 facing the drum, and a roller receiving portion 16 having a wedge-shaped receiving surface 15 formed in the main body case 5 facing the drum. A braking roller 19 is pivotally supported by a U-shaped roller arm 18 inserted through a pair of long notched holes 17, 17 bored at both ends, and the braking roller 1 is provided between the roller arm 18 and the roller receiving portion 16.
a compression coil spring 20 that urges 9 to come into pressure contact with the brake drum 14 using the wedge-shaped receiving surface 15 as a guide; An operating pedal 24 having a substantially triangular cross section is pivotally supported by a pin 23 on the outer facing surface of the roller receiving portion 16, and a rib 25 of the roller arm 18 and a stopper rib 26 are formed on the opposing inner surface of the roller receiving portion 16. are doing.

Next, the operation in the above configuration will be explained. The normal brake condition when power cord 3 is pulled out is 5th.
As shown in the figure, the upper surface of the operating pedal 24 is horizontal, and as shown in FIG.
The cord reel 4 is brought into pressure contact with the brake drum 14 of the cord reel 4 using the wedge-shaped receiving surface 15 of the cord reel 4 as a guide.

Next, when releasing the brake, the operating pedal 24
When the pedal 24 is pushed downward from above with the foot or hand as shown by the dotted line in Fig. 5, the lower end of the operating pedal 24 moves inward and the roller arm 18 in close contact with the pedal 24 rotates in the opposite direction to the rotational direction of the cord reel 4 via the fulcrum rib 25 as shown in Fig. 6, and the brake roller 19 pivoted to the roller arm 18 moves away from the brake drum 14. This releases the brake state of the cord reel 4, allowing the cord reel 4 to rotate in the direction of the arrow and wind up the power cord 3.

When the vacuum cleaner 1 is placed and fitted into the parts storage case 10, the operating pedal 24 comes into contact with the upper end of the parts storage case 10 and is pushed up into the recess of the roller receiver 16 as shown in FIG. When the cord reel 4 is stored, the brake can be released. Therefore, even if the vacuum cleaner 1 is placed and fitted in the parts storage case 10 with the power cord 3 pulled out (including partially pulled out), the power cord 3 can be inserted through the outlet 12 without any problem. The cord is automatically wound onto the cord reel 4.

Effects of the invention Since the vacuum cleaner with a parts storage case according to the present invention is constructed as described above, it is easy to forget the operation of winding the pulled-out power cord into the cord reel and place the vacuum cleaner in the parts storage case. The power cord will automatically be wound up. In addition, since the drawer (inlet) is located above the mounting surface, the winding operation can be performed smoothly, and the cord can be pulled out while the vacuum cleaner is mounted and fitted in the parts storage case. This also improves usability.
