Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage battery type electric vacuum cleaner using a storage battery as a power source for a fan motor.

BACKGROUND ART Conventionally, a hand-type or stick-type vacuum cleaner is generally known as a vacuum cleaner having a built-in storage battery.
A floor-moving type electric vacuum cleaner in which a small-capacity (up to 12 V) storage battery is built in is proposed. The structure will be described with reference to FIG. 5. Reference numeral 1 is a dust-collecting case containing a filter body 2, and a hose insertion port 3 is provided at a front end portion thereof. Reference numeral 4 denotes a cleaner body having a fan motor 5 and a storage battery 6 built-in, and a switch 7 and a handle 8 provided above the dust collector case 1. The dust collection case 1 is detachably attached to the front end of the cleaner body 4. The storage battery 6 has a voltage of 8 to 12 V, and is arranged below the handle 8 and behind the fan motor 5. The front and rear sides of the fan motor 5 are supported via support rubbers 9 and 10, and the front surface is the filter body 2
It is pressed against the rear surface. Reference numeral 13 is a caster roller provided on both sides of the lower rear end of the cleaner body 4.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention As described above, in the conventional storage battery type vacuum cleaner, the storage battery 6
It was very inconvenient because the cleaner body 4 had to be disassembled at the time of replacement.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a floor-moving type storage battery type electric vacuum cleaner having a simple structure and allowing easy replacement of the storage battery.

Means for Solving the Problems In order to achieve the above object, the present invention provides a cleaner main body having a dust collecting part and a fan motor built therein, and a rear part of the cleaner main body, the rear opening of which is opened and closed by a lid. And a storage battery that is detachably held by an upper open box-shaped holding portion provided inside the lid body and is stored in the battery housing portion. A structure in which the lower rear side is pivotally supported by the cleaner body so as to be rotatable in the front-rear direction, and a connection terminal electrically contacting the output terminal of the back of the storage battery is arranged on the front wall side of the battery storage section. Is.

Operation According to the above configuration, when the lid is opened, the storage battery pops out from the battery storage portion of the cleaner body, and the storage battery can be easily put in and taken out. In addition, the open or closed state of the lid is reliably maintained due to the relationship of the shaft support position, and in particular, the moment of the storage battery or the like ensures electrical connection in the closed state.

Example Hereinafter, the example will be described with reference to the accompanying drawings.

In FIGS. 1 to 4, the cleaner body 11 is constructed by combining the upper and lower bodies 12a and 12b. The upper body 12a has a dust collecting portion 13 formed on the upper side thereof and a battery housing portion 14 formed on the rear side thereof, and a lid 15 for covering the opening of the dust collecting portion 13 is pivotally supported by a rotating shaft 16 on the upper surface thereof. The closed state of the lid body 15 is held by the buckle 17. A bag-shaped filter 19 supported by a holder 18 and a secondary filter 20 made of non-woven fabric are housed in the dust collecting portion 13. A handle 22 that is rotatable via a rotation shaft 21 is provided on the upper end of the upper body 12a.
Is provided. The fan motor 23 has upper and lower support rubbers 24 and 25 for the upper and lower bodies 12a and 12b.
It is elastically supported via the suction side and is in contact with the dust collecting portion 13. Reference numeral 26 is a bumper made of an elastic rubber material, which is held between the upper and lower bodies 12a and 12b. Reference numeral 27 is an exhaust port formed on both sides of the upper body 12a. A lid 29 that covers the opening 28 provided on the rear surface of the cleaner body 11 is rotatably attached to the battery storage portion 14 via a support shaft 30. The lid 29 has a box-shaped holding portion 3 that has an opening at the top and stores the storage battery 31.
2 is provided, and a stop portion 34 formed of a cylindrical convex portion that fits into an arcuate concave portion 33 centered on the support shaft 30 formed on the side wall of the battery housing portion 14 is provided on both side surfaces. Further, above the lid 29, a buckle 37 engaged with a square hole 35 formed in the side wall of the battery housing portion 14 by the action of a spring body 36 is attached, and a storage battery 31 is provided with a handle 38. There is. A connection terminal 39 is attached to the battery storage portion 14 and is connected to the fan motor 23. Next, the operation of this configuration will be described. First, since the opening is provided in the rear surface of the cleaner main body 11, the shape of the upper surface can be designed without any restrictions on taking out, and the parts such as the handle 22 can be freely provided. Further, since the lid 29 is provided with the stop portion 34 that defines a constant opening angle and the holding portion 32 that holds the storage battery 31 slidably in the vertical direction, a space for holding the storage battery 31 as shown in FIG. Can be sufficiently secured, and at the same time, it can be taken out obliquely upward and inserted obliquely downward, so that it is easy to hold and easy to operate. Further, the center of gravity of the storage battery 31 with respect to the support shaft 30 is on the front side when closed in FIG. Therefore, the turning force acts in the closing direction to smooth the closing operation and at the same time, the connecting terminal 39
Secure contact pressure to. Further, when opened in FIG. 2, a turning force acts in the opening direction, which contributes to holding the lid 29 at a constant opening angle.

EFFECTS OF THE INVENTION As described above, according to the present invention, a battery storage portion, whose rear opening is opened and closed by a lid, is formed on the back of the cleaner body, and an upper open box-shaped holding portion provided inside the lid. While holding the storage battery in a detachable manner, the lid body is configured to be rotatable in the front-rear direction by pivotally supporting the lower rear side of the holding portion to the cleaner body, and further to the front wall side of the battery storage portion. Since the connection terminal for electrically connecting to the output terminal on the back of the storage battery is arranged, the storage battery can be easily put in and taken out by opening the lid, and since the putting in and out direction is diagonally upward, operability is also improved. Good. Also, since the lower rear side of the holding part is pivotally supported by the cleaner body, from the relationship between the center of gravity of the storage battery and the pivot point,
Since the lid receives a force that is held in either the open or closed direction, it is easier to move in and out of the storage battery, and the electrical connection characteristics with the storage battery are improved to enable good operation. Is.
