[0032] 1. Outline structure of vacuum cleaner
[0033] 1.1. Appearance and composition of the vacuum cleaner
[0034] On the upper part of the front side of the vacuum cleaner 1, such as figure 1 As shown, a start switch 3 of the vacuum cleaner 1, a suction force adjustment dial 4 for adjusting the suction force, a socket (output terminal) 7 for supplying electric power to the outside, and the like are provided.
[0035] In addition, in the vacuum cleaner 1 of this embodiment, when the starter switch 3 is set to "on", the motor 5 for dust collection (refer to image 3 ) start, when the start switch 3 is set to "off", the motor 5 stops. In addition, when the starter switch 3 is set to "interlocking", the motor 5 and the electric tool 50 connected to the socket 7 (refer to figure 2 ) is a linked mode in which the start and stop are performed in conjunction with the start and stop.
[0036] Incidentally, in the vacuum cleaner 1 of the present embodiment, as figure 2 As sho...

[0075] 1. Outline of the vacuum cleaner of this embodiment
[0076] In the first embodiment, the current accumulation value obtained by accumulating the current value as it is is used as the current variable, but in the present embodiment, the current value is based on the product of the energization time T2 and the count value of the number of times the energization state is reached. , that is, it is determined whether or not to start energizing the motor 5 based on a value corresponding to the cumulative value of the energization time T2 from the start of supply of the supply current.
[0077] Here, the so-called power-on state, such as Figure 7 As shown, it refers to the state where the absolute value of the current value of the supply current is greater than 0, and the specified current value io or more is smaller than the maximum current value. The so-called energization time T2 refers to the time to reach the energization state. The number of times to reach the energiz...

[0123] In the above-mentioned embodiment, the accumulated threshold value σ and the like (hereinafter simply referred to as threshold value) for determining whether to start energizing the motor 5 are fixed values stored in ROM. However, in this embodiment, the threshold value can be changed by user operation.
[0124] Specifically, as Figure 11 (a) and Figure 11 As shown in (b), condition changing means such as an interlocking sensitivity switching switch 27A or an interlocking sensitivity switching knob 27B for changing the threshold is provided.
[0125] In addition, the interlocking sensitivity selector switch 27A can change the time from when the electric tool is started to when the electric motor 5 is started (hereinafter referred to as interlocking sensitivity.), and the interlocking sensitivity switching knob 27B can continuously change the interlocking sensitivity. . In this way, in this embodiment, the startup timing of the cleaner can be made more appropriate....
