An operation panel 123 b is provided on the handle portion 123 a of the hand operation unit 123, and the operation panel 123 b has various operation switches that control the operation of the steam vacuum cleaner 100. The types of operation switches include a switch that starts or stops suction cleaning that sucks in dust on the surface to be cleaned, a switch that starts or stops steam cleaning on the surface to be cleaned, and starts or stops wiping cleaning of the surface to be cleaned. There is a switch to make. In addition, the kind of operation switch is not limited to these, The switch which starts or stops any two of suction cleaning, steam cleaning, and wiping cleaning may be sufficient, and all of suction cleaning, steam cleaning, and wiping cleaning are sufficient. It may be a switch for starting or stopping. Moreover, you may combine the switch which switches the strength of suction amount and the strength of steam ejection amount individually.

  A suction tool 130 is connected to the distal end of the extension pipe 121, and a water supply port 45 is provided in the upper part of the suction tool 130 in the illustrated example. Hereinafter, the configuration of the suction tool 130 will be described in detail.

  FIG. 2 is a bottom view of the suction tool 130 according to the first embodiment. The “front side” shown in FIG. 2 represents the front side of the suction tool body 10 in the traveling direction, and the “rear side” represents the rear side of the suction tool body 10 in the traveling direction. FIG. 2 shows the structure of the bottom surface of the suction tool 130, that is, the bottom surface facing the surface to be cleaned of the suction tool body 10.

  The suction tool 130 includes the suction tool main body 10 and a connection pipe 50 that is connected to the extension pipe 121 of FIG. 1 and communicates the suction tool main body 10 with the extension pipe 121. In FIG. 2, the connection pipe 50 is fixed to the suction tool body 10, but the suction tool body 10 has a structure in which the forward side and the reverse side of the suction tool body 10 are reversed.

  In the lower case 11 of the suction tool body 10, a suction port 20 located on the front side of the suction tool body 10, a wiping member 31 having dust collecting properties located on the rear side of the suction tool body 10, and the suction port 20. A plurality of steam spouts 41 located between the wiping member 31 and the wiping member 31 are formed. Inside the suction tool body 10, there are provided a drive unit 32 for driving the wiping member 31, and a steam generating unit 42 for generating steam by heating water supplied from a tank, which will be described later, with a heater.

  The wiping member 31 can be removed from the drive unit 32, and a water-absorbing member that can be reused by washing is used. However, if the surface to be cleaned can be wiped, its material and The structure is not limited.

  When performing the wiping cleaning of the surface to be cleaned by the wiping member 31, the driving unit 32 moves the wiping member 31 to the surface to be cleaned from the bottom surface of the lower case 11 to move the surface from the lower case 11 to the surface to be cleaned. The wiping member 31 is pressed against the surface to be cleaned by the biasing force that faces. On the other hand, when the drive unit 32 does not wipe and clean the surface to be cleaned by the wiping member 31, the wiping member 31 is removed from the surface to be cleaned so that the wiping member 31 does not touch the surface to be cleaned. The wiping member 31 is moved away from the surface to be cleaned by being pulled and moved to the bottom surface side.

  The mechanism by which the drive unit 32 drives the wiping member 31 may be either mechanical or electrical.

  In the case of the mechanical type, a spring mechanism using a restoring force of an elastic body such as a push spring, a torsion spring, or a leaf spring can be considered. Specifically, when wiping and cleaning is started, the mechanical drive unit 32 holds the elastic body in an accumulated state before pressing the wiping member 31 and a manual operation lever (not shown) is operated. The restoring force accumulated in the elastic body is transmitted to the wiping member 31 in response to the operation of the manual operation lever. Thereby, the wiping member 31 is pressed and moved from the bottom surface of the lower case 11 to the surface to be cleaned, and the wiping member 31 is pressed against the surface to be cleaned. When stopping the wiping and cleaning, the mechanical drive unit 32 is configured such that when a manual operation lever (not shown) is operated, the wiping member resists the biasing force of the elastic body in response to the operation of the manual operation lever. 31 is pulled back to the lower case 11 side, and the elastic body is held in a stored state.

  In the case of the electric type, a mechanism using an electric actuator that converts electric energy into linear motion or rotational motion is conceivable. Specifically, when wiping cleaning is started, the electric drive unit 32 is electrically operated in conjunction with a command from the hand operating unit 123 when the wiping cleaning start operation is performed with the operation switch described above. The urging force generated by the actuator is transmitted to the wiping member 31. Thereby, the wiping member 31 is pressed and moved from the bottom surface of the lower case 11 to the surface to be cleaned, and the wiping member 31 is pressed against the surface to be cleaned. When stopping the wiping cleaning, the electric drive unit 32 is operated by the tension generated by the electric actuator in response to a command from the hand operating unit 123 when the wiping cleaning is stopped by the operation switch described above. By transmitting the force to the wiping member 31, the wiping member 31 is pulled back to the lower case 11 side. The electric drive unit 32 is driven by the supply of electricity from the cleaner body 110 shown in FIG. 1, and can be reduced in size as compared with the mechanical drive unit 32.

FIG. 3 also shows the upper case 13, the lower case 11, the wiping unit 30, the steam ejection unit 40, the water supply channel 44, and the water supply port 45 that constitute the suction tool main body 10. Although not shown in FIG. 3, the suction tool main body 10 includes a rotary brush that is housed in a suction chamber 15 that communicates with the suction port 20 and removes dust on the surface to be cleaned, and an electric motor for driving the rotary brush. It shall be provided.

  The steam ejection part 40 is composed of a steam generation part 42 and a tank 43. In the illustrated example, the steam generating unit 42 is installed inside the lower case 11, but the installation location of the steam generating unit 42 is not limited to the illustrated example, and may be fixed to the side surface of the upper case 13, for example. In the illustrated example, the tank 43 is provided above the steam generating unit 42. However, the position of the tank 43 is not limited to the illustrated example. For example, the tank 43 may be installed on the wiping unit 30 or the upper case. You may fix to 13.

  One end of the water supply path 44 is connected to the tank 43, and the other end of the water supply path 44 is arranged so that the upper case 13 protrudes to the outside. It is assumed that the water supply path 44 functions as a water supply port 45 for supplying water to the tank 43 and is formed at a position that does not obstruct the air path between the suction port 20 and the connection pipe 50. It is assumed that the water supply port 45 is provided with a sealing mechanism for preventing the water stored in the tank 43 from leaking outside.

  In the illustrated example, the tank 43 is used as the water supply means to the steam generating unit 42, but the water supply means is not limited to the tank 43. For example, the suction tool main body 10 is configured such that an external water supply container such as a beverage plastic bottle or a steel can can be attached. Further, the water supply container is connected to the water supply port 45 or the water supply path 44, and the steam generating unit 42 is connected. It may be configured to supply water.

  The wiping unit 30 includes a wiping member 31 and a drive unit 32. In the illustrated example, the drive unit 32 is installed inside the lower case 11, but the installation location of the drive unit 32 is not limited to the illustrated example, and may be fixed to the side surface of the upper case 13, for example.

Cleaning possible in this state is as follows. (1) Implementation of only wiping and cleaning. (2) Implementation of suction cleaning and wiping cleaning. (3) Implement steam cleaning and wiping cleaning. (4) Implementation of suction cleaning, steam cleaning and wiping cleaning.

  In the suction tool main body of Patent Document 1, the wiping member pushed downward from the bottom surface of the suction tool main body by manual operation of the operation lever is locked to the base disposed in the storage portion of the suction tool main body. Therefore, when the user pulls the suction tool main body, the pressure with which the wiping member is pressed against the surface to be cleaned is lowered, and the surface to be cleaned is not sufficiently wiped off, or moisture remains during steam cleaning. .

  In the suction port body of Patent Document 2, the wiping member is attached to the lower surface of the suction port body. Therefore, as in Cited Document 1, when the user pulls the suction tool body, the pressure with which the wiping member is pressed against the surface to be cleaned is reduced, and the dirt on the surface to be cleaned is not sufficiently wiped off, or during steam cleaning. Moisture left behind occurs.

  According to the suction tool 130 of the first embodiment, the wiping member 31 is pressed against the surface to be cleaned by the urging force from the lower case 11 toward the surface to be cleaned.

When it is detected that 10 has moved to the front side, steam is ejected, and when it is detected that the suction tool body 10 has moved to the rear side, the ejection of steam is stopped. Moreover, when the drive part 32 detects that the suction tool main body 10 is moving to the front side based on the traveling direction information detected by the roller 14, the wiping member 31 is cleaned on the surface to be cleaned when the suction tool main body 10 moves backward. The wiping member 31 is pressed with a pressing force larger than the pressing force. With this configuration, when the suction tool main body 10 moves forward, it is possible to prevent moisture remaining on the surface to be cleaned from being wiped off, and to effectively remove dirt from the surface to be cleaned. There is no possibility that the surface to be cleaned is pressed and the surface to be cleaned is damaged. Further, when the suction tool main body 10 moves backward, the moisture of the steam is prevented from adhering to the surface to be cleaned. In particular, this configuration is effective when the suction port 20, the steam ejection port 41, and the wiping member 31 are arranged in the order shown in FIG. In addition, when the mechanical drive part 32 is employ | adopted, the mechanism in which the pressing force of the wiping member 31 changes according to the advancing direction of the suction tool main body 10 shall be provided. For example, the two drive members 32a shown in FIGS. 3 and 4 are movable mechanisms having the above-described elastic body, and when the suction tool main body 10 is moving forward, the wiping member corresponds to one rotation direction of the roller 14. An assist force for pressing 31 is applied to the movable mechanism. When the suction tool main body 10 is moving backward, the assist force is released corresponding to the other rotation direction of the roller 14. In the first embodiment, the roller 14 is used as a means for detecting the advancing direction of the suction tool body 10 or a means for adjusting the pressing force of the wiping member 31, but the means for detecting the advancing direction and the pressing force are used. The means for adjusting is not limited to the roller 14.

As shown in FIG. 8, when only the front wiping member 31-1 is pressed and moved toward the surface to be cleaned, the front wiping member 31-1 is strongly pressed against the surface to be cleaned, and the dirt on the surface to be cleaned is effective. Can be removed.

  Furthermore, in Embodiment 3, since the front side wiping member 31-1 and the front side steam generation part 42-1 are provided in the front side of the suction inlet 20, even if it does not replace front and back of the suction tool main body 10, ie, a suction tool Even if the main body 10 is not rotated, steam cleaning and wiping cleaning of the floor and corners of the room are possible.

  Moreover, you may comprise the suction tool 130-2 of Embodiment 3 as follows. The suction tool main body 10 according to the third embodiment has a function of detecting the traveling direction of the suction tool main body 10 based on the rotation direction of the roller 14, and the rear drive unit 32-2 is based on the traveling direction information detected by the roller 14. When the suction tool body 10 is detected to move to the front side, the rear side wiping is performed with a pressing force larger than the force with which the front drive unit 32-1 presses the front wiping member 31-1 against the surface to be cleaned. The member 31-2 is pressed against the surface to be cleaned. When the front drive unit 32-1 detects that the suction tool main body 10 has moved to the rear side based on the traveling direction information detected by the roller 14, the rear drive unit 32-2 detects the rear wiping member. The front wiping member 31-1 is pressed against the surface to be cleaned with a pressing force larger than the force pressing the 31-2 against the surface to be cleaned. With this configuration, when the suction tool body 10 moves forward and backward, it is possible to prevent the moisture remaining on the surface of the steam that has adhered to the surface to be cleaned from being wiped off, and to effectively remove the dirt on the surface to be cleaned. At this time, there is no possibility that dust is pressed against the surface to be cleaned and damages the surface to be cleaned.

  Moreover, you may comprise the suction tool 130-2 of Embodiment 3 as follows. The suction tool main body 10 according to the third embodiment includes a proximity sensor that detects an approach to a structure such as a wall or a column on the front side of the suction tool main body 10, and the front steam generation unit 42-1 is based on information from the proximity sensor. When it is detected that the front side of the suction tool main body 10 has approached the structure, steam is ejected from the front steam generation unit 42-1. Moreover, when the front side wiping part 30-1 detects that the front side of the suction tool main body 10 has approached the structure based on information from the proximity sensor, the rear side driving part 32-2 has the rear wiping member 31-. The front wiping member 31-1 is pressed against the surface to be cleaned with a pressing force larger than the force pressing 2 against the surface to be cleaned. With this configuration, it is possible to perform steam cleaning and wiping cleaning of the floor of the room and the corner of the wall without rotating the suction tool body 10 and replacing the front and back of the suction tool body 10.

  As described above, the suction tools 130, 130-1, and 130-2 according to the first, second, and third embodiments include the suction port, the steam ejection portion, and the bottom surface of the suction tool body from the bottom surface of the suction tool body. And a wiping unit that generates an urging force toward an opposite surface to be cleaned and presses the wiping member against the surface to be cleaned by the urging force to wipe the surface to be cleaned. With this configuration, the wiping member 31 is pressed against the surface to be cleaned by the urging force from the lower case 11 toward the surface to be cleaned, and the lifting of the wiping member 31 from the surface to be cleaned is suppressed. A decrease in pressure with the cleaning surface is suppressed. Therefore, the dirt on the surface to be cleaned can be effectively wiped off. Moreover, according to suction tool 130,130-1,130-2 which concerns on Embodiment 1,2,3, since suction cleaning, steam cleaning, and wiping cleaning can be implemented, the cleaning tool which performs these cleaning separately The cleaning time can be shortened as compared with the case of using, and the contamination of the surface to be cleaned that cannot be removed by an individual cleaning tool can be effectively removed, so that the cleaning area can be expanded.

  The configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
