Abstract

A vacuum cleaner includes a main body portion, a secondary battery, an electric blower, a handle and a conductive member. The secondary battery is disposed in the main body portion. The electric blower operates by electric power supply from the secondary battery. The handle is one which a user contacts when the vacuum cleaner is used. At least a part of the conductive member is disposed at the handle and conducts static electricity generated due to operation of the electric blower.

First claim

What is claimed is:

1. An electrical equipment, comprising:
a main body portion;
a battery disposed in the main body portion;
an operating unit which operates by electric power supply from the battery;
a handle that is a human body contacting portion which a user contacts in gripping the handle when the electrical equipment is used;
a conductive member at least a part of which is disposed in the handle and is exposed outside the handle; and
a circuit board having a predetermined pattern, wherein
the conductive member or a pattern connected to the conductive member electrically and the predetermined pattern of the circuit board are disposed at a predetermined distance from each other, and
within the predetermined distance, dielectric breakdown of air is caused between the conductive member or the pattern connected to the conductive member electrically and the predetermined pattern by receiving a potential of static electricity from the predetermined pattern and micro discharge is performed via the conductive member and a user gripping the handle.

2. The electrical equipment according to claim 1 , wherein the handle is a main body holding portion which holds the main body portion.

3. The electrical equipment according to claim 2 , wherein at least a part of the conductive member is provided at a lower portion of the handle.

4. The electrical equipment according to claim 3 , wherein
the handle is provided with an uneven slip resistance portion at the lower portion of the handle, and
at least a part of the conductive member is disposed so as to be substantially flush with a projecting shape of the slip resistance portion of the handle.

5. The electrical equipment according to claim 2 , wherein
the handle is provided with an uneven slip resistance portion at a lower portion of the handle, and
at least a part of the conductive member is disposed so as to be substantially flush with a projecting shape of the slip resistance portion of the handle.

6. The electrical equipment according to claim 1 , further comprising a connecting portion which is connected to the main body portion,
wherein the handle is a connecting gripping portion which grips the connecting portion.

7. The electrical equipment according to claim 1 , wherein the human body contacting portion is composed of the conductive member.

8. The electrical equipment according to claim 1 , wherein the conductive member is disposed on an outer surface of the human body contacting portion.

9. The electrical equipment according to claim 1 , wherein the conductive member is a carbon-containing member.

10. The electrical equipment according to claim 1 , wherein the conductive member is a conductive soft member.

11. The electrical equipment according to claim 1 , wherein
the handle is formed in an elongated shape, and
at least a part of the conductive member is provided at positions in a longitudinal direction of the handle.

12. The electrical equipment according to claim 1 , wherein
the handle is formed in an elongated shape, and
at least a part of the conductive member is provided in a substantially middle portion in a longitudinal direction of the handle.

13. The electrical equipment according to claim 1 , wherein at least a part of the conductive member is disposed so as to be substantially flush with the handle.

14. A vacuum cleaner comprising the electrical equipment according to claim 1 .

15. The vacuum cleaner according to claim 14 , further comprising a connecting portion which is connected to the main body portion, wherein
the handle is a connecting gripping portion which grips the connecting portion, and
the connecting portion is an air duct body provided with a hose body.
