産業上の利用分野
本発明は整流子モーターを動力源とする電動機器の使用
時間表示装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a usage time display device for electric equipment using a commutator motor as a power source.

ずしも一致しないという問題を有していた。Conventional configurations and their problems Conventionally, household commutator motor electric appliances have very rarely been equipped with operating time display devices, and some appliances that have this type of device have an hour display on the circuit. It was common to have a built-in meter. However, this method is very expensive and has the problem that the display time and the carbon brush life of the commutator motor (carbon plan replacement time) do not necessarily match.
発明の目的
本発明はこのような従来の問題を解消し、安価でかつカ

By doing so, the change in the finger blade part that moves with the carbon brush which decreases with use will inform the total usage time of the device and the appropriate time to replace the carbon plan.

In FIGS. 1 to 6, 1 is a commutator motor for a vacuum cleaner incorporating a circular fan, 2 is a commutator that constitutes a part of the commutator motor 1, 3 is a carbon flage, and 4 are the same≦carbon brush cap, 6 is a spring that presses the carbon brush 3 against the commutator, and 6 is a pointer unit that is integrally formed with the carbon brush 3 by being press-fitted into a hole provided in the carbon brush 3. , 7 is a vacuum cleaner incorporating the commutator motor 1, and 8 is a transparent display window provided on the top surface of the vacuum cleaner 7 outside the main body.
上記構成において動作を説明すると、掃除機本体を使用

とができると共に、カーボンブラシ3の寿命(取替え時
期)を明確に示すことが可能となる。To explain the operation in the above configuration, when the vacuum cleaner body is used, that is, when the commutator motor 1 is operated, the carbon brush 3 is reduced due to friction with the commutator 2, and according to this reduction amount, the carbon brush 3 is integrally reduced. The shaped pointer moves. Once the rotational speed of the commutator motor 1 and the material of the carbon brush 3 are determined, the amount of decrease in the carbon brush 3 can be determined in a unified manner by comparing it with the usage time, and therefore the amount of change in the pointer section 6 is used. The time can be displayed on the display window 8, and the lifespan (replacement time) of the carbon brush 3 can be clearly indicated.
なお、上記実施例では、表示内容を「使用時間」という

用時間に関連することで他の目的に応用することもii
J能であり、たとえば、前記電気掃除機を例に上げれば
、「ゴミ捨て時期表示」ということで一定使用時間ごと
にゴミ捨て時期を示すこと等も1り能である。In addition, in the above embodiment, the display content is limited to 5'+1Ll- as "usage time", or depending on the device to which it is applied, it may be applied to other purposes related to usage time.
For example, taking the vacuum cleaner as an example, it is also possible to display a ``garbage disposal time display'' to indicate when it is time to throw away the garbage after a certain period of use.
また、上記実施例では、指針部をカーボンブラシと別部
品で構成したが、表示窓との位置関係等を考慮すれば、
指針部をカーボンブラシ自身の一部に形成することも’
1能であり、さらに安価な表示装置も容易に構成できる
ものである。In addition, in the above embodiment, the pointer part was made up of a carbon brush and a separate part, but considering the positional relationship with the display window, etc.
It is also possible to form the pointer part as part of the carbon brush itself.
1 function, and a display device that is inexpensive can also be easily constructed.

とができるものである。Effects of the Invention As is clear from the above embodiments, the use time display device of the present invention is an inexpensive and reliable display device because the amount of carbon brush reduction can be directly viewed from the outside of the device. In addition, by considering the display contents, the scope of application can be easily expanded.
