Abstract
A hand vacuum cleaner has an airflow path from an air inlet to a clean air outlet with an air treatment member and a fan and motor assembly in the air flow path. The hand vacuum cleaner has a cleaner body and a handle having a hand grip portion. The hand vacuum cleaner also includes a plurality of batteries. A portion of the motor and fan assembly and/or a portion of a filter component can be positioned beside and/or between at least some of the batteries. The batteries may be contained in a removable storage chamber. The storage chamber may be removably mounted to the hand vacuum cleaner beside and/or around at least a portion of a filter and/or fan and motor assembly. The batteries may be at a lower part of the hand vacuum cleaner, such as below a handle.
Claims19
A hand vacuum cleaner having a front end, a rear end, an upper end and a lower end, the hand vacuum cleaner comprising:
- (a) a main body;
- (b) an air flow path from an air inlet to a clean air outlet with an air treatment member provided in the air flow path;
- (c) a fan and motor assembly provided in the main body, the fan and motor assembly is positioned in the air flow path downstream of the air treatment member, the fan and motor assembly having a motor axis of rotation, the fan and motor assembly having a first lateral side that is laterally spaced in a first direction from the motor axis of rotation and a second lateral side that is laterally spaced in a second direction from the motor axis of rotation wherein the second direction is opposite to the first direction;
- (d) a handle;
- and,
- (e) a removeable energy storage member pack that is removably mountable to the main body, the removeable energy storage pack comprising:
- a first lateral housing section enclosing a first plurality of energy storage members,
- a second lateral housing section separate from the first lateral housing section, the second lateral housing section enclosing a second plurality of energy storage members separate from the first plurality of energy storage members, and
- a laterally extending web joining a lower end of the first lateral housing section and a lower end of the second lateral housing section, the web being an outer surface of the removable energy store, isolated from the air flow path and external to the first and second housings, and
- wherein the removeable energy storage member pack is upwardly mountable to a mounted position in which the fan and motor assembly is nested between the first and second lateral housing sections.
