When 0 is used alone, only the drive switch is operated.

Next, the operation of the steam cleaner 1 constructed as above will be described. First, a case where the steam cleaner 1 is used by being connected to the electric vacuum cleaner 100 will be described.

When the steam type vacuum cleaner 1 is used by connecting it to the electric vacuum cleaner 100, as described above, the suction hose 1 is used.
The connection pipe 104 of the ventilation pipe 40, that is, the connection pipe 44 of the steam cleaner 1 is connected to the connection pipe 104 of 03, and the female connector 108 and the male connector 75 are connected to connect the steam cleaner 1 to the electric vacuum cleaner 100. To do. Then, the steam generator drive switch (not shown) is closed. Then, the heater 73 of the steam generator 70 is energized via the power supply line 74, and after a predetermined time, the peripheral wall of the through hole 72 of the steam generator 70 is heated almost instantly to a state where water becomes steam, that is, steam. It On the other hand, the relay means 85 starts timing from the time when the steam generator 70 is energized, and when the predetermined time is reached, power supply to the pump 80 is started to drive the pump 80. This pump 80
Is driven, the water stored in the water storage tank 60 is supplied to the steam generator 70, and this water is almost instantaneously generated as steam and sent to the steam ejector 32 via the steam supply pipe 58. , Is ejected from the ejection port 32a toward the floor. When steam is ejected from the steam ejector 32, the drive switch (not shown) is closed to drive the electric motor blower. When the electric blower is driven, the suction action of the electric blower causes the suction port 1 formed in the upper case 11 of the steam cleaner 1 to be sucked.
External air is sucked in through the fan 3, and this air is sucked in through the fan storage chamber 29, the ventilation pipe 40 and the suction hose 103.

When the sucked air, that is, the sucked airflow, passes through the fan storage chamber 29 forming a part of the suction air passage, the fan 35 rotates to generate a rotational force. It is transmitted to the rotating shaft 34 that rotates together with the fan 35, and when the rotating shaft 34 rotates, the vibration generator 36 attached to the rotating shaft 34 rotates. The rotation of the vibrating body 36 causes the case 21, that is, the cleaning device 20 to vibrate, and the vibration is transmitted to the brush 33, so that the tip of the brush 33 makes sliding contact with the floor surface. That is, as described above, the brush 33 makes a sliding contact operation by the rotational force of the fan 35 transmitted through the vibrating body 36.

Since the weight of the steam cleaner 1 is applied to the brush 33, the tip of the brush 33 is brought into sliding contact with the floor surface in a pressed state, and at this time, the steam ejector is used. Since the steam is jetted from 32, dirt on the floor surface or dirt adhered firmly to the floor surface can be reliably and reliably caused by the softening and cleaning action of the steam and the sliding contact action of the brush in the pressed state. It is quickly removed or cleaned.

The steam ejected from the steam ejector 32 during the cleaning is provided below the intake port 13 formed in the main body case, that is, the upper case 11, in other words, the ejector. Since the intake port 13 is provided at a position higher than the disposition portion 27, the steam is not sucked into the electric vacuum cleaner 100 together with the suction airflow sucked from the intake port 13, and Fan storage room 29, elastic ventilation tube 3
7. Since the suction air passage including the connecting pipe 14 and the ejector arrangement portion 27 are airtightly isolated, steam is not sucked into the electric vacuum cleaner 100 through the suction air passage, and therefore, It is possible to prevent performance deterioration of the electric motor constituting the electric blower or deterioration of the insulating member.

Next, the case where the steam cleaner 1 is used independently by connecting it to the electric vacuum cleaner will be described. The steam type vacuum cleaner 1 is used alone when cleaning, for example, a window glass, a wall or a ceiling. Window glass like this,
The cleaning of the wall or ceiling is rather inferior in operability when vibration is generated, and in many cases it can be sufficiently cleaned only by spraying steam, and cleaning while moving the electric vacuum cleaner 100 is rather difficult to clean. Therefore, it is required to be used alone.

When the steam cleaner 1 is used alone, the connecting pipe 44 of the steam cleaner 1 is removed from the connecting pipe 104 of the suction hose 103, and the female connector 108 is connected to the male connector. 75 is removed, and this male connector 75 is connected to a cord (not shown) connected to a power source for use. And male connector 75
Is connected to the cord connected to a power source, the heater 73 of the steam generator 70 is energized via the power supply line 74 as described above, and after a predetermined time, the peripheral wall of the through hole 72 of the steam generator 70 is The water is heated almost instantaneously to a state where it becomes steam, that is, steam, while the relay means 85 starts timing from the time when the heater 70 is energized, and when the predetermined time is reached, power is supplied to the pump 80. To drive the pump 80. When the pump 80 is driven, the water stored in the water storage tank 60 is supplied to the steam generator 70, and the water is generated almost instantaneously as steam and is supplied to the steam ejector 32 via the steam supply pipe 58. It is sent, the window glass from the spout 32a,
It is ejected toward the surface to be cleaned such as a wall or ceiling. In this state, the main body 10 is moved by the operation handle 43 to slide the brush 33 of the cleaning device 20 on the surface to be cleaned such as the window glass for cleaning. In this case, since the cleaning device 20 does not vibrate and the electric vacuum cleaner 100 is not connected, the operation is easy, and since the suction hose 103 is not provided, the cleaning operation of the steam cleaner 1 is easy. is there. Further, as described above, stains and the like on the surface to be cleaned such as the window glass, the wall or the ceiling are sufficiently cleaned by jetting steam. In addition, when cleaning the window glass, the ceiling, etc. as described above, the cleaning device 20 is located above the water storage tank 60, and when cleaning the floor surface, the cleaning device 20 is located above the water storage tank 60. Since it is located below, in the former case, the water in the water tank 60 moves to the rear side and there is no water in the front side, when the water tank 60 is full, and in the latter case. On the contrary, it is conceivable that the water in the water storage tank 60 moves to the front side and there is no water on the rear side, and the water is not fed by the pump 80. Water supply in which the other end of the pipe provided with an outlet to be connected is branched so that the inlet of one of the branched pipes is located at the front end side of the water storage tank 60 and the inlet of the other pipe is located at the rear end side. Water tank with pipe 60

In the above embodiment, the brush 33 is used as the cleaning member, but the cleaning member is not limited to the brush 33 and may be a thin rubber plate or a mop member. .

Further, in the above embodiment, the intake port 1
Although 3 is provided on the ceiling wall 11a of the upper case 11, it may be formed on the annular wall 11b, but it may be formed on the ceiling wall 11a from the viewpoint of more reliably preventing the inflow of steam. desirable.

Further, in order to prevent the steam ejected from the steam ejector 32 from being sucked together with the suction airflow from the intake port 13 formed in the upper case 11,
As shown in FIG. 4, a flange-shaped blocking member for blocking the upward flow of steam is provided on the outer peripheral portion of the base 22 of the case 21 of the cleaning device 20 forming the other side of the main body case, that is, the outer peripheral portion of the ejector installation portion. 22a is formed, the steam spouted from the steam spouting device 20 is prevented by the blocking member 2
The upward flow is blocked by 2a, and the intake port 13
