Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a power nozzle section having a rotating brush, an electric blower, and a dust collecting section, and a cleaner body which is rotatable up and down with respect to the power nozzle section. A flexible suction hose which is connected to a communication hole provided in the cleaner body via a straight pipe, and the other end of which is detachably connected to a connection port communicating with the suction port of the power nozzle section via a connection pipe. The present invention relates to an upright type electric vacuum cleaner provided with.

[0002]

2. Description of the Related Art As disclosed in Japanese Utility Model Publication No. 62-45629, a conventional upright type electric vacuum cleaner has a power nozzle portion having a rotating brush, an electric blower, and a dust collecting portion, and the above power A cleaner body that is rotatable up and down with respect to the nozzle part, and a connection port that connects one end to a communication hole provided in the cleaner body through a curved pipe and the other end to the suction port of the power nozzle part. And a flexible suction hose that is detachably connected via a connection pipe, and the bent pipe is configured to be rotatable in a plane perpendicular to the axis of the communication hole.

[0003]

In the upright type electric vacuum cleaner having the above-mentioned structure, the bent pipe is a hindrance when the vacuum cleaner body is tilted to clean under a desk or bed. However, there is a problem that the main body of the vacuum cleaner cannot be tilted by the amount of the bent tube, and the bottom of the desk or bed cannot be cleaned sufficiently. The upright type electric vacuum cleaner of the present invention has been made in view of the above problems, and a communication hole is provided in a recess provided in the back surface of the cleaner body, and a straight pipe of a suction hose is inserted and connected to the communication hole. Thus, the purpose of the present invention is to make it possible to tilt the main body of the vacuum cleaner to a large extent and to reliably clean the bottom of the desk, bed, etc.

[0004]

In order to achieve the above object, an upright type electric vacuum cleaner according to the present invention has a power nozzle section having a rotating brush, an electric blower and a dust collecting section, and at the same time has the above power. A cleaner body that is rotatable up and down with respect to the nozzle part, and a connection port that connects one end to a communication hole provided in the cleaner body via a straight pipe and the other end to the suction port of the power nozzle part. And a flexible suction hose removably connected to the vacuum cleaner main body, a recess is provided in the back surface of the cleaner body, the communication hole is provided in the recess, and the straight pipe of the communication hole is inserted. The insertion portion to be connected and the straight pipe are formed to have the same length, and the straight pipe is inserted and connected to the insertion portion. A protective guard is provided near the communication hole of the cleaner body to protect the suction hose from coming into contact with and damaging the cleaning surface when the cleaner body is laid down for cleaning.

[0005]

With the above structure, only the diameter of the suction hose protrudes to the back of the cleaner body, so that the cleaner body can be greatly tilted down and the bottom of the desk or bed can be reliably cleaned. Since a straight pipe is used instead of a bent pipe for connection to the cleaner body, the flexible suction hose is bent at the bent portion on the back of the cleaner body, and when dust is clogged in this portion. Dust can be easily removed by simply extending the suction hose in a straight line. Further, the protective guard prevents the cleaning surface and the suction hose from coming into contact with each other when the cleaner body is tilted, thereby preventing damage to the suction hose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of an upright type vacuum cleaner of the present invention will be described with reference to FIGS. The electric vacuum cleaner of the present invention includes a power nozzle unit 1 having a rotating brush (not shown), an electric blower (not shown), and a dust collecting unit 2, and is rotated up and down with respect to the power nozzle unit 1. A movable cleaner body 3 is connected at one end to a communication hole 4 provided in the cleaner body 3 through a straight pipe 5, and the other end is connected to a suction port (not shown) of the power nozzle unit 1. And a suction hose 8 having flexibility, which is detachably connected to the connection port 6 via a connection pipe 7.

A recess 9 is provided on the back surface of the cleaner body 2,
The communication hole 4 is provided in the recess 9, and the straight pipe 5 and the insertion portion 4a for inserting and connecting the straight pipe 5 of the communication hole 4 are formed to have the same length, and the straight pipe 5 is inserted in the insertion portion 4a. Inserted and connected.

The upright type electric vacuum cleaner having the above structure is
Only the diameter of the suction hose 8 protrudes to the back surface of the cleaner body 2, so that the cleaner body 2 can be largely tilted down, and the bottom of the desk, bed, etc. can be reliably cleaned, and moreover, the cleaner body 2 Since the straight pipe 5 is used for the connection to the vacuum pipe without using a bent pipe, the flexible suction hose 8 is bent at the bent portion on the rear surface of the cleaner body 2, and when dust is clogged in this portion. The dust can be easily removed by simply extending the suction hose 8 in a straight line.

Another embodiment of the first embodiment will be described with reference to FIG. 3. When the straight pipe 5 is inserted around the communication hole 4, the distal end of the straight pipe 5 is guided so as to facilitate the inserting operation. The guide part 10 is provided. Then, the guide portion 10
Since the straight pipe 5 is guided by the straight pipe 5, the straight pipe 5 can be easily and surely inserted and connected at the time of mass production of the upright electric vacuum cleaner having the above configuration.

Next, a second embodiment of the upright type electric vacuum cleaner of the present invention will be described with reference to FIGS. In the second embodiment of the electric vacuum cleaner of the present invention, when the cleaner main body 2 is tilted near the communication hole 4 on the rear surface of the cleaner main body 2 for cleaning, the suction hose 8 comes into contact with the cleaning surface and is damaged. A protection guard 11 is provided to protect the protection. In the upright type electric vacuum cleaner having the above structure, the protective guard prevents the cleaning surface and the suction hose from coming into contact with each other when the cleaner main body is tilted, and reliably prevents the suction hose from being damaged.

[0011]

Since the upright type electric vacuum cleaner of the present invention has the above-mentioned structure, only the diameter of the suction hose projects to the back of the cleaner main body, and the cleaner main body can be greatly tilted. The bottom of the vacuum cleaner body is flexible because it can clean the desk and bed underneath, and the connection to the vacuum cleaner body uses a straight tube instead of a curved tube. If the suction hose that it has is bent and dust is clogged in this part, the dust can be easily removed by simply extending the suction hose in a straight line. Further, the protective guard prevents the cleaning surface and the suction hose from coming into contact with each other when the cleaner body is tilted, thereby preventing damage to the suction hose.
