[Means to solve the problem]

In order to solve the above-mentioned conventional problems, the upright type vacuum cleaner of the present invention has a core. The cord winding drum is set so that its center line of rotation is approximately parallel to the floor surface, and the cord winding drum is A passage is formed at the lower end of the cord storage chamber that covers the collecting drum to communicate with the lower end surface of the dust collection section. It is something that can be achieved.

[0005] Further, the lower end opening of the passage communicating from the cord storage chamber to the lower end surface of the dust collector is It runs perpendicular to the passageway and opens only toward the front.

[0006]

[Effect]

In this invention, fine dust that enters the cord storage chamber from the outside is removed from the lower end of the cord storage chamber. It falls downward under its own weight through a passageway installed in the wall, and is automatically discharged to the outside. . This effect is particularly exacerbated by the vibrations that occur when pulling out or storing cords. It is something. Furthermore, while the main unit is in use, cords are generally not stored properly due to heat generation from the cord surface. The temperature inside the storage room becomes high, but in this case there is a connection below the cord winding drum to the outside. Because a passageway is formed, the airflow is caused by natural convection from below to above. Since the cord exits from the exit part, the cord surface and the inside of the cord storage chamber are automatically cooled. can be done.

[0007] In addition, the lower end passage outlet of the passage communicating downward from the lower end of the cord storage chamber is By opening only in the front direction of the body, fine dust falling from the cord storage chamber can be directly This will prevent it from falling to the floor. In other words, it falls from the cord storage room. The fine dust accumulates at the bottom of the passage, and when the user wants to remove it, the entire dust collection section must be moved forward. Since it can be taken out intentionally only when tilted, etc., the cord can be stored without your knowledge. It is possible to prevent the floor surface etc. from being contaminated by fine dust falling downward from the room. or, The lower end opening of the passage opens toward the front, so when the main body is in use, By moving the cord forward, an airflow is generated from the opening toward the cord storage section. It acts as a so-called air intake duct to cool the cord and cord storage room. can be performed even more efficiently.

【Example】

Embodiments of the present invention will be described below with reference to FIGS. 1 to 5. In the figure, 11 is dust. A floor nozzle section that has a built-in rotating brush 12 that scrapes up The dust collecting part 13, which is tiltably provided in the part, has an electric blower 14 for dust suction and A dust collection bag 15 for storing the cord 16 and a winding drum 17 for storing the cord 16 and the cord A brake button 18 for releasing the braking device of the card winding drum 17 is provided. electric The blower 14 is connected to the rotating brush 12 by a belt 19. Said floor The waste portion 11 and the dust collection portion 13 are connected by a detachable hose 20. Dust collection section The front part of the dust collection bag 13 is opened and closed with a removable dust collection chamber lid 21 for taking out the dust collection bag 15. It has a removable attachment 22 on the surface, and an exhaust port 21a on the bottom surface. have

[0009] An operating handle 23 is attached to the upper end of the dust collecting section 13, and a The handshake part 23a is integrally formed, and a cord hook is provided at the bottom of the handshake part 23a. 24 is attached. 25 is detachably attached to the rear surface of the dust collecting section 13. An extension pipe 26 is a cover that houses a cord winding device, and a cord outlet section 26a. on the top surface, and a dust receptacle that protrudes forward approximately parallel to the floor surface at the bottom end. 26b. 27 is a moving roller, and 28 is a main shaft. 29 is the dust collection section 13 A cord storage chamber 13b constitutes the cord storage chamber 29 formed by the cover 26 and the cord storage chamber 13b. A fine dust outlet 30 is formed with an inclination at the lower end of the wall surface forming the dust collecting part 13. A fine dust passage is formed with the cover 26, and 31 is a fine dust outlet.

0010 The operation of the above configuration will be explained below. By driving the electric blower 14 The rotating brush 12 rotates, and the dust stirred up by this is sent to the electric blower 14. Due to the suction force, the dust is sucked into the dust collecting section 13 through the hose 20. Suction into the dust collection section 13 The drawn dust is collected in the dust collection bag 15, and the purified air is discharged from the exhaust port 21a. Expelled outside.

[0011] The fine dust that entered the cord storage chamber 29 from the cord outlet part 26a moves downward under its own weight. from the fine dust outlet 13b through the fine dust passage 30 and onto the fine dust receiving part 26b. down. When the user wants to take out the fine dust on the fine dust receiving part 26b, the user should do the following as shown in FIG. Either tilt the dust collecting part 13 forward or take it out intentionally from the fine dust outlet 31. I can do that.

0012 The above configuration prevents fine dust and cotton spores from entering the cord storage chamber 29 from above. Debris, etc. will not accumulate in the cord storage chamber 29 and will be discharged naturally. This may cause the cord to become dirty, the floor surface to become dirty, or even the cord winding drum to rotate. It is possible to prevent abnormalities from occurring. Also, the emission from the surface of code 16 If the temperature inside the cord storage chamber 29 rises due to heat, etc., the temperature inside the cord storage chamber 29 will increase due to natural convection. Since this air is taken in, cord 16 etc. can be automatically cooled and further When the main body is in use, the dust collecting section 13 moves forward and opens toward the front. The fine dust outlet 31 serves as an air intake duct and sends airflow upward. Therefore, the cooling effect can be further enhanced.

[0013]

[Effect of the idea]

As is clear from the explanation of the above embodiments, the upright type vacuum cleaner of the present invention According to this, by providing a passage leading from the lower end of the cord storage chamber to the lower surface of the dust collector It prevents fine dust from accumulating in the cord storage chamber, and also provides a cooling effect for the cord. It is something that can be done.

[0014] Further, the lower end opening of the passage may be made substantially perpendicular to the passage and open only in the front direction. This prevents fine dust that has fallen carelessly through the passageway from falling directly onto the floor. In addition to preventing the unit from moving forward, outside air can be automatically taken in as the unit moves forward. Therefore, the cooling effect of the cord can be realized even more effectively.
