The dust on the surface 47 is blown up, and the dust collection efficiency is improved. On the other hand, since dust that is entangled in the velves and the like that does not blow up even if a part of the wake 43 is blown up is scraped up by the rotating brush 45, sufficient dust collection efficiency can be secured even in the velves and other surface conditions. It can also be used on the surface to be cleaned. Moreover, since all the wakes are not immediately discharged to the outside of the cleaner body, it is possible to prevent discharge of fine dust. Further, since the part 43 of the wake is sprayed on the surface 47 to be cleaned, the buoyancy F2 is applied to the nozzle portion 38.
Occurs, and the running resistance is reduced. As described above, it has become possible to obtain an upright electric vacuum cleaner that is superior to the conventional one while ensuring sufficient dust collection efficiency even in the case of rust. (Embodiment 3) An embodiment of the third means of the present invention will be described with reference to FIG. The basic structure of the upright type electric vacuum cleaner of the present embodiment is the same as that of FIG. 1, and therefore its explanation is omitted, and the different points will be mainly described.

る。Since the operating state of each element and the cleaning mechanism when the cleaner is operated in the above-mentioned configuration are the same as those in the third embodiment, the description thereof will be omitted. In the present embodiment, the blowout port 70 is maintained at a predetermined angle p ° so as to blow out a part 69 of the wake in the direction of the suction port 65 with respect to the surface to be cleaned 72, and the effect thereof will be described. The relationship between the quantitative ratios of the air flow 76 and the air flow 77 is such that the ratio of the air flow 77 increases when the angle p ° is larger than 90 °, and the angle p ° is 9 °.
If it is smaller than 0 °, the proportion of the air flow 76 becomes large. Here, if the ratio of the air flow 77 is large, the dust blown up will go in the direction opposite to the suction port 65, and the dust collection efficiency will decrease. Further, the airflow 75 that should be rectified by the gap 78 formed by the flat surface portion 71 and the surface to be cleaned 72 collides with the airflow 77 and becomes unrectified, and the dust collection efficiency is also reduced. Therefore, the smaller the air flow 77, the higher the dust collection efficiency. In this embodiment, since the angle p ° is 90 ° or less, the ratio of the air flow 77 is small and therefore the dust collection efficiency is high. As described above, in the present embodiment, the dust collection efficiency can be further improved as compared with the third embodiment. (Embodiment 5) An embodiment of the fifth means of the present invention will be described with reference to FIG. The basic structure of the upright type electric vacuum cleaner of the present embodiment is the same as that of the other embodiments, and therefore the description thereof will be omitted, and the difference will be mainly described. In the figure, 79 is a cleaner body, 80 is a handle used to move the cleaner body 79,
