Rechargeable vacuum cleaner system
First Claim
1. A rechargeable vacuum cleaner system, comprising:
- a vacuum cleaner having a body case;
a storage chamber provided in said body case, the storage chamber having an opening;
a battery assembly housed in said storage chamber through the opening;
a heat transfer wall configured to constitute a portion of said storage chamber;
a temperature-detecting element for detecting a temperature of said battery assembly;
a charger to charge the battery assembly and including a charging stage; and
a charge-controlling part provided in the charging stage to control charge of the battery assembly, wherein a resilient member is provided in said storage chamber to thermally couple the battery assembly with the heat transfer wall, wherein said charger includes a heat transmission part which constitutes a portion of the charging stage and which has a heat transmitting surface, wherein the heat transfer wall of the storage chamber is thermally connected to the heat transmission surface of the heat transmission part of the charger and a circuit including the charge-controlling part for charging the battery assembly is established between the vacuum cleaner and the charger when the vacuum cleaner is coupled with the charging stage of the charger, and wherein said charge-controlling part is configured to control a charge current of the battery assembly based on a comparison of a temperature of the battery assembly detected by the temperature-detecting element with a predetermined charge permissible temperature range during the charge of the battery assembly.
