Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a vacuum cleaner equipped with a display device such as a fluorescent display tube.

Structure of Conventional Example and its Problems A conventional vacuum cleaner of this type will be explained with reference to FIGS. 1 and 2. 1 is the vacuum cleaner body;
A motor 2 and a motor cover 3 provided to cover the motor 2 are built inside the motor. Further, a body top 4 is fixed to the upper part of the motor cover 3, and a printed circuit board 5 on which electronic components 6 such as resistors, capacitors, and transistors are mounted is attached inside the body top 4. 7 is an LED attached to the printed circuit board 5, which is covered with an LED cover 8 made of transparent resin, etc.
It can emit light to the outside. Further, 9 is a protective cover provided to prevent a user from touching electronic components such as the electronic component 6. 10 is LED7 LED
It's a foot.

The above is a conventional configuration, but with this configuration, if the protective cover 9 is stepped on from above or an object is dropped, which is generally considered to be the case with vacuum cleaners, the protective cover 9 will not only be damaged. It also caused a problem with LED7.
The LED legs 10 may break, in which case the display function of the vacuum cleaner will be impaired. Furthermore, the LED legs 10 were sometimes broken due to vibrations and shocks during use and transportation.

Purpose of the invention The present invention solves these conventional problems and provides a vacuum cleaner with improved vibration resistance, strength resistance, and ease of assembly.

Structure of the invention In the vacuum cleaner of the invention, a display support plate integrally formed of elastic resin or the like is provided on the top surface of the printed circuit board on which the display is mounted, and the display support plate has a tip that touches the end surface of the display. A plurality of contacting support portions are formed to protrude diagonally upward. The end face of the display device is held down by the supporting portion, and this structure absorbs vibrations and shocks.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figures 3 to 7, 11
1 is a vacuum cleaner main body, and a fan motor 12 and a motor cover 13 provided to cover the motor 12 are built inside the vacuum cleaner main body. Further, a printed circuit board box 14 is fixed to the upper part of the motor cover 13, and inside thereof is a main printed circuit board 15 on which electronic components 16 such as resistors, capacitors, and transistors are mounted, and a fluorescent display tube 1.
7. A display printed circuit board 19 equipped with a display device such as an LED 18 is attached.

The display printed circuit board 19 includes a fluorescent display tube 17,
In order to fix the LED 18, an elastic display support plate 20 made of resin or the like is provided. As shown in FIGS. 6 and 7, the display support plate 20 is provided with a support portion 21 in the form of a projection diagonally upward toward the end surface of the fluorescent display tube 17. 22 is a fluorescent display tube foot of the fluorescent display tube 17.

Furthermore, a smoked window 23 is provided on the top of the display printed circuit board 19 to prevent components other than the fluorescent display tube 17 and the LED 18 from being seen to the outside. In addition, a transparent window 24 is provided on the top surface of the smoked window 23.
has. Further, 25 is a protective cover provided to prevent the user from touching electrical components such as the electronic component 16, and 26 is a body provided to cover the motor chamber 27, to which the protective cover 25 is fixed. .

According to the above configuration, the fluorescent display tube 17 is supported by the support portion 21 of the display support plate 20;
The display support plate 20 is made of an elastic material such as resin, and the support portion 21 projects obliquely upward toward the end surface of the fluorescent display tube 17, so that the force that presses down the fluorescent display tube 17 is always exerted. Therefore, even if vibration is applied to the cleaner body 11, the support portion 21 of the display support plate 20 absorbs the vibration and no force is applied to the fluorescent display tube leg 22.
Therefore, erroneous display due to bending of the fluorescent display tube leg 22 can be prevented, and reliability is improved. Furthermore, it is possible to similarly prevent the fluorescent display tube foot 22 from breaking even if an impact is applied, such as by being stepped on from above or by a falling object.

Further, according to this configuration, although the support part 21 of the display support plate 20 serves as a guide and firmly supports the fluorescent display tube 17, the display support plate 21
Another advantage is that it can be assembled from above very easily.

Effects of the invention As is clear from the above examples, the vacuum cleaner of the present invention can improve vibration resistance, impact resistance, and ease of assembly by improving the support method of the fluorescent display tube. It is.
