When this electric blower is driven, external air is sucked through the intake holes 13 formed in the upper case 11 of the steam cleaner 1a by the suction action of this electric blower. Suction is performed via the suction hose 103.
[0054]
Further, when steam is ejected from the steam ejector 32, the control knob 143 is operated to drive the electric fan 140 and supply air to the steam ejector 32. By supplying this air, the temperature of the steam ejected from the steam ejector 32 is lowered. That is, steam whose temperature has dropped from the steam ejector 32 is ejected.
[0055]
When the sucked air, that is, the sucked airflow, passes through the fan housing chamber 29, the fan 35 rotates to generate a rotational force, and this rotational force is transmitted to the rotating shaft 34 that rotates together with the fan 35. The vibration generator 36 rotates together with the shaft 34. The lower case 21, that is, the cleaning body 20 is vibrated by the rotation of the vibrating body 36, and this vibration is transmitted to the brushes 33 and 33, and the tip portions of the brushes 33 and 33 are in sliding contact with the floor surface. That is, as described above, the brushes 33 and 33 operate so as to slidably contact the floor surface by the vibration of the vibrating body 36 that rotates together with the fan 35.
[0056]
  Further, since the substantially total weight of the steam type vacuum cleaner 1a is applied to the brushes 33, 33, the tips of the brushes 33, 33 are in sliding contact with the floor surface pressed, and at this time Since the steam is ejected from the steam ejector 32, dirt on the floor surface or dirt adhered firmly to the floor surface is softened and cleaned by the steam and slidably contacted in the pressed state of the brushes 33 and 33. Easy and reliable removal by actionit canIs.
[0057]
  In addition, air flows from the electric fan 140 to the steam blower 32.Being suppliedTherefore, steam whose temperature is lowered is ejected from the ejection port 32a, and therefore, it is possible to prevent deterioration of the floor surface made of a material vulnerable to high temperature.
[0058]
  in this wayReference exampleSimilarly to the steam cleaner 1 in the first embodiment, the steam cleaner 1a can be cleaned while sliding the floor surface with the brushes 33 and 33 by operating the cleaning body 20 while jetting steam. In addition, it is possible to easily and reliably remove and clean the floor dirt or the dirt firmly attached to the floor, and supply air, that is, outside air to the steam blower 32 by the electric fan 140 as described above. Since the temperature of the steam ejected from the outlet 32a is lowered, it is possible to prevent the deterioration of the floor made of a material susceptible to high temperatures.
[0059]
In addition, the steam temperature can be freely changed by operating the control knob 143 to change the amount of air supplied to the steam blower 32 by changing the number of rotations of the electric fan 140 including stopping, so that it is necessary. Accordingly, the temperature of the steam can be adjusted over a wide range.
[0060]
  Also,Reference exampleThen, the steam temperature drop means is constituted by the electric fan 140Since theThe amount of air supplied to the steam blower 32,By controlling the amount of current supplied to electric fan 140Easy by adjusting the rotation speedThere is an advantage that you can. Further, since the outside air is supplied to the steam blower 32 to lower the temperature of the steam, the temperature can be lowered efficiently with a small amount of air, and thus the air supply means, that is, the electric fan 140 is made small. be able to. Also, aboveReference exampleThen, the air supply means is arranged in the case 51 of the steam generator 50, but it may be arranged in the main body 10.
[0061]
  Also thisReference exampleAlso in the steam type vacuum cleaner 1a, when performing normal cleaning, the suction port body (not shown) is connected to the connecting pipe 104, and the drive switch 115 is closed to perform cleaning.
[0063]
  In addition, the first implementation of this inventionIn formThe steam type vacuum cleaner has been described as being connected to the main body of the electric vacuum cleaner. However, except for the invention according to claim 2, for example, the cleaning body is driven without being driven by the suction airflow. Of course, it is possible to reduce the temperature of the steam by using a steam-type vacuum cleaner of a type that drives the cleaning body by vibrating with an electromagnetic vibration device or a type that does not drive the cleaning body.
[0064]
【The invention's effect】
The invention according to claim 1 configured as described above is capable of cleaning while operating the cleaning body while spraying steam and sliding the floor surface by the cleaning member, and adheres firmly to the floor surface or the floor surface. It is possible to easily and reliably remove and clean the filth, etc., and to lower the temperature of the steam that is ejected from the ejection section by providing a steam temperature lowering means, thereby preventing deterioration of the floor made of a material that is vulnerable to high temperatures The effect that it can be produced.
[0065]
  Claim 1In the described invention, the temperature of the steam is lowered by the exhaust air of the main body of the vacuum cleaner.Because of the exhaust airIt is possible to produce an effect that steam can be sprayed well on the floor surface by promoting steam ejection.
