本発明は、例えば、車内などの掃除に便利な小型、コン
パクトの充電式電気掃除機に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a small and compact rechargeable vacuum cleaner that is convenient for cleaning the inside of a car, for example.

ものとなっていた。Conventional configurations and their problems Most conventional vacuum cleaners of this type have a charger consisting of a step-down transformer and a charging control circuit built into the vacuum cleaner body. However, this type of vacuum cleaner was heavy due to the effects of the charger, especially the transformer inside it, making it extremely difficult to use when cleaning the inside of a small car.

きの分だけ変化して制御回路に伝わり、正確な制御がで
きなくなる欠点があり、これより信頼性の面で問題゛が
あった。In order to solve this problem, it has been considered that the charger is provided separately from the vacuum cleaner itself. In this case, the charger's control circuit detects the charging completion voltage of the battery because the length of the low-voltage cord of the charger is around 2tn, and there are variations in connection resistance to the connection part of the vacuum cleaner body. If an attempt is made to prevent overcharging, the terminal voltage of the battery changes by the amount of variation described above and is transmitted to the control circuit, making accurate control impossible, which leads to problems in terms of reliability. .

も確実となる。Structure of the Invention The rechargeable vacuum cleaner of the present invention has a filter, a fan motor, a secondary battery serving as a power source for the fan motor, and a charging control circuit for the secondary battery built into the vacuum cleaner body, and further includes the vacuum cleaner body. The vacuum cleaner has a connection part for connecting the low voltage side of the external transformer to the charging control circuit, and only the control circuit is installed inside the vacuum cleaner itself, making it lighter, smaller, and more compact. In addition, the battery can be charged more reliably.

排気口８に至る排気用通風路９の途中に臨ませである。In the figure, a vacuum cleaner body 1 is composed of a main body part 2 and a dust box 4 detachably connected to the main body part 2 via a buckle 3. The main body part 2 has a built-in fan motor 5, a secondary battery 6 serving as a power source for the fan motor 5, and a charging control circuit 7 for the secondary battery 6. The charging control circuit 7 is located in the middle of an exhaust air passage 9 extending from the fan motor 5 to an exhaust port 8 formed on the side surface of the main body 2.

冷却されるものである。In the above configuration, when the fan motor 5 is now driven, the dust-containing air that has flowed in through the suction port 11 is filtered through the filter 12.
Only the dust is collected in the dust box 4. The purified air after passing through the filter 12 is passed through the ventilation passage 9.
The air is discharged from the exhaust port 8 through the exhaust port 8. At this time, the charging control circuit 7 is effectively cooled by the air flowing through the ventilation path 9.

電池６に光電々流が流れてその充電が行われる。Next, when charging the secondary battery 6 in the vacuum cleaner body 1, connect the connecting plug 14 led out from the low voltage side of the external transformer 13 to the connecting part 15, and the secondary battery 6 will be charged via the charging control circuit 7. A photocurrent flows and the battery is charged.
そして充電が完了すると、２次電池６の端子電圧が上昇
するので、これを充電制御回路７が検知してその後の充
電々流を規制し、同２次電池６が過充電になるのを防止
するものである。When charging is completed, the terminal voltage of the secondary battery 6 increases, so the charging control circuit 7 detects this and regulates the subsequent charging flow to prevent the secondary battery 6 from being overcharged. It is something to do.
