Further, as shown in FIG. 7, on the upper surface of the tip pipe 34, there are provided an operation button 38 for turning on / off the operation of the vacuum cleaner main body 37 and adjusting the suction force, and a tip for operating the vacuum cleaner main body 37. It has a dust amount display window 33 for displaying the amount of dust passing through the pipe 34 to the outside. Here, in FIG. 8, reference numeral 44 denotes a dust detection sensor comprising a light emitting element 45 and a light receiving element 41. When the dust passes through the suction passage 40 together with air from the A, and when the dust passes through the dust detection sensor 44, the dust is detected. The display is performed while changing the number of lights by a plurality of LEDs 39 provided in proportion to the passing amount. And the tip pipe 34
The light emission of the LED 39 is visually recognized from the dust amount display window 33 provided on the upper surface of the device.

However, in the conventional configuration as described above, the dust amount display window 33 is flush with the operation button 38, and during cleaning, as shown in FIG. Since the state is inclined forward, there is a problem that the visibility of the dust amount display window 33 provided on the upper surface of the end pipe 34 is deteriorated.

Then, this invention solves such a conventional subject, and an object of this invention is to provide the vacuum cleaner which made the visibility of the dust amount display favorable.

Means for Solving the Problems In order to achieve the above object, the invention according to claim 1 of the present invention provides a hose having a connection pipe connected at one end to a vacuum cleaner main body, and a hose connected to the other end of the hose. A tip pipe, an extension pipe and a floor nozzle connected to the tip pipe, and a dust detection sensor for detecting dust passing through the dust passage, wherein the tip pipe displays a dust amount above the dust passage. A housing for accommodating the display element is formed, a grip portion is provided on the hose side of the housing to be separated from the dust path, and a window for visually recognizing a display by the display element is provided on an upper surface of the accommodation section. An operation unit for operating the operation of the vacuum cleaner main body is disposed on the grip portion side, and the window is provided with an inclined surface which becomes lower as it goes from the extension tube side to the grip portion side.

In the invention according to claim 2 of the present invention, a lens is provided between the display element and the window.

The invention according to claim 3 of the present invention further includes a hose having a connection pipe connected to the vacuum cleaner main body at one end,
A tip pipe connected to the other end of the hose, an extension pipe and a floor nozzle connected to the tip pipe, and a dust detection sensor for detecting dust passing through the dust passage; An accommodation portion for accommodating a display element for displaying the amount of dust is formed at an upper portion, a grip portion separated from the dust passage is provided on the hose side of the accommodation portion, and an opening is provided on the upper surface of the accommodation portion. An operation unit for operating the operation of the vacuum cleaner body is disposed on the grip portion side, and a display plate on which the display element is disposed faces the opening, and one end of the display plate on the grip portion side is turned to the tip pipe. The tilt angle can be freely adjusted by freely supporting the shaft.

In the invention according to the first aspect, the window for visually confirming the display by the display element is provided with the inclined surface that becomes lower as it goes from the extension tube side to the grip portion side. Properties can be improved.

According to the second aspect of the present invention, by providing the lens, the visibility of the dust amount display is further improved.

According to the third aspect of the present invention, one end of the display panel on which the display element is disposed on the grip portion side is rotatably supported on the distal end pipe so that the tilt angle can be adjusted, so that the visual recognition suitable for the user's physique can be achieved. A good inclination angle can be selected.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 5 denotes a hose, one end of which has a connection pipe 6 connected to the vacuum cleaner main body 7, and the other end of which is connected to the tip pipe 4. Tip pipe 4 is floor nozzle 1, extension pipe 2
Combined with The tip pipe 4 has a grip portion held by the user's hand during cleaning and an operation button 20 for performing operation operations such as turning on and off the vacuum cleaner, and a dust amount indicating the amount of dust passing through the hose 5 during cleaning. A display unit is provided.

2 and 3, the distal end pipe 4 is connected to a dust passage 8.
And a dust detection sensor including a light emitting element 12 and a light receiving element 13 for detecting the amount of dust passing through the dust passage 8. On the pipe 10, a housing for housing an electronic circuit for calculating the amount of dust detected by the dust detection sensor is formed.

Also, multiple LEs that display the amount of dust calculated by the electronic circuit
D9 is provided in the accommodating portion, and the number of lighted LEDs 9 is changed in proportion to the amount of dust. In addition, a dust amount display window 3 is provided on the upper surface of the housing portion facing the LED 9. On the hose 5 side of the housing part, a grip part separated from the pipe 10 is formed. Further, the dust amount display window 3 is provided with an inclined surface that becomes lower as it goes from the extension tube 2 side to the grip portion side, so that the visibility of the LED 9 during cleaning is good.

In FIG. 4, since the prism-shaped lens 15 is provided between the LED 9 and the dust amount display window 3, the visibility is further improved by the lens effect.

Further, in FIG. 5, the LED 9 and the lens
15 and fix the shaft 17 to one side of the
Are provided so that the display plate 16 rotates about the shaft 17.

Display panel 16 with LED 9 and lens 15 mounted on the top of the housing
There is an opening that faces. Further, a fixing portion 18 having a valley-and-valley shape is formed on the opposite side of the axis 17 of the display plate 16, and the inclination angle can be selected by engaging the valley portion of the fixing portion 18 with the opening edge of the opening. Like that. This way the display board
Since 16 inclination angles can be selected, visibility can be improved according to the user's physique.
