  The suction inlet main body 21 is provided with a connecting pipe 14a protruding rearward at the center in the longitudinal direction (width direction) of the horizontally long main body 22 so as to be suitable for cleaning the flooring floor F (see FIGS. 3 to 6). Is formed. The main body 22 has a bottom plate 23 and a cover 24 connected thereto, and a bumper 25 covers the bottom plate 23 and a cover 24 covering the bottom plate 23 from above on the front peripheral surface of the main body 22. It is installed in between.

  The suction port main body 21 is provided with a suction port 26 that opens to the bottom plate 23 facing the lower surface, that is, the surface to be cleaned such as the flooring floor F. The suction port 26 extends in the longitudinal direction of the main body 22 as shown in FIG. The suction port 26 communicates with the inlet 14 b of the connection pipe 14 a through the internal space of the main body portion 22, that is, the suction chamber 27.

  2 to 4, reference numeral 28 denotes a roller used for smoothly moving the suction port body 14 along the flooring surface F. The roller 28 is rotatably attached to a rear protruding portion 22a of the main body portion 22 in which the suction port main body 21 covers the inlet 14b portion of the connection pipe 14a from the lower side. The roller 28 has a raised cloth covering its peripheral surface. The roller 28 can be omitted.

  The detection means 31 is used to detect the advance and retreat of the suction port body 14 moved along the flooring floor F by being pushed and pulled in the front-rear direction by the user's hand holding the hand operation unit 16. The suction port body 21 is attached. As shown in FIGS. 5 and 6, the detection means 31 includes a detection roller 32 and a detection switch 33.

  As shown in FIG. 2, the detection roller 32 is rotatably supported by a roller holder 34 fixed to the bottom plate 23. The lower portion of the detection roller 32 protrudes from the bottom plate 23 so as to come into contact with the flooring floor F through a hole 23a formed in the bottom plate 23 as shown in FIGS. A convex portion 32 a is provided on the peripheral surface of the detection roller 32 located in the main body portion 22.

  The detection switch 33 includes a micro switch having an operation lever 33a, and is located in the vicinity of the detection roller 32, for example, in the vicinity of the front side of the detection roller 32 (the side on which the suction port body 4 is pushed and moved) and is incorporated in the main body unit 22. Has been. The detection switch 33 is, for example, turned on when the contact 33b is pushed in a predetermined amount or more by the operating lever 33a (see FIG. 5), and turned off when the contact is not pushed in the predetermined amount (see FIG. 6). in use. The operating lever 33a is biased by a biasing spring (not shown) in a direction away from the contact 33b.

  The steam generator 36 is attached to the suction inlet body 21, and includes a water tank (not shown), a steam generator that heats water supplied from the tank with an electric heater, and instantly evaporates, and a steam flow controller ( 37). The steam generator 36 has an open / close lid 36 a for supplying water to the water tank, and the open / close lid 36 a protrudes outside the cover 24 so that it can be opened and closed from the outside of the cover 24.

  The steam flow control unit 37 is responsible for outflow of steam and its stop, and is composed of an electromagnetic on-off valve. The steam flow control unit 37 opens and closes a flow path related to the outflow of steam, specifically, a water channel from the water tank to the steam generation unit, or a steam path from the steam generation unit to the steam ejection unit 41. . The steam flow control unit 37 has a biasing spring (not shown) that keeps the flow path closed in a non-energized state, and opens the flow path in the energized state. Since the detection switch 33 is inserted in the energization circuit for the steam flow control unit 37 as shown in FIG. 7, energization to the steam flow control unit 37 and its interruption (non-energization) are performed by turning on / off the detection switch 33. It is performed by turning off.

  The steam outflow operation from the steam generator 36 and its stop can be selected by the steam switch 19b. This selection can be performed by switching between energization and de-energization of the electric heater of the steam generating unit by ON / OFF operation of the steam switch 19b, or alternatively, energization and non-energization of the steam flow control unit 37. It can also be performed by switching between energization.

  The steam ejection part 41 is provided connected to the downstream side of the steam flow control part 37. In the present embodiment, in order to reduce the number of flow path members forming the steam flow path, a steam header 41a that is directly provided in the steam generator 36 and into which steam is introduced as the steam flow control unit 37 is opened, It consists of a large number of jet nozzles 41b that protrude downward from the steam header 41a and are arranged in a line. The steam generator 36 and the steam ejection part 41 integrated in this way form a steam ejection unit. The width A of the steam ejection part 41 is smaller than the width B of the suction port 26. As shown in FIGS. 3 and 4, the steam ejection unit 41 is installed in the main body portion 22 of the suction port body 21 with the ejection nozzle 41 b facing the suction port 26 from directly above. In this case, when viewed from below, the suction port main body 21 is provided such that the steam ejection portion 41 is located at the center in the width direction of the suction port 26 as shown in FIG. The steam ejection part 41 can also be connected to the steam generator 36 via a flow path member. In this case, the degree of freedom of arrangement of the steam generator 36 and the steam ejection part 41 with respect to the main body part 22. Can be increased by the flow path member.

  Each of the first wiping member 45, the second wiping member 46, and the third wiping member 47 is made of a member having good water absorption, for example, a cloth, preferably a raised cloth made of cloth having raised hair.

  As shown in FIG. 2, the first wiping member 45 is attached to the outer surface of the bottom plate 23 so as to be positioned on the front side of the steam ejection portion 41, that is, on the front side of the suction port 26 when the suction port body 21 is viewed from below. The first wiping member 45 has substantially the same length as the row formed by the ejection nozzle 41 b and extends in the longitudinal direction of the suction port body 21. The first wiping member 45 can be omitted.

  As shown in FIG. 2, the second wiping member 46 is attached to the outer surface of the bottom plate 23 so as to be located on the rear side of the steam ejection portion 41, and hence on the rear side of the suction port 26 when the suction port body 21 is viewed from below. Yes. The second wiping member 46 has a length equal to or longer than the length of the row formed by the ejection nozzles 41 b and extends in the longitudinal direction of the suction port body 21.

  The third wiping member 47 is attached to the outer surfaces of both ends of the bottom plate 23 with the suction ports 26 positioned on both sides in the longitudinal direction when the suction port body 21 is viewed from below. These third wiping members 47 can be omitted.

  When the canister-type vacuum cleaner 11 having the above-described configuration is used, the electric blower 15 is operated with the hand operating part 16 of the suction air passage body 13 held, and then the suction port is connected via the extension pipe 18. The flooring F can be cleaned by pushing and pulling the body 14 back and forth along the flooring F.

  In this case, when the steam switch 19b of the operation panel 19 is turned on, the steam mode accompanied by the ejection of steam is selected. As a result, the steam generator 36 is energized, and steam is generated by the steam generator 36.

  By the way, as the suction port body 14 is pushed and pulled in the front-rear direction, the moving direction is detected by the detecting means 31. That is, when the suction port body 14 is pushed forward and moved forward, the detection roller 32 rotates clockwise in FIGS. 5 and 6 due to contact with the flooring floor F, so that the convex portion 32a of the detection roller 32 is provided. The actuating lever 33a of the detection switch 33 that is pushed and moved by the position of the detection switch 33 pushes the contact 33b of the detection switch 33 over a predetermined amount (see FIG. 5).

  As a result, the detection switch 33 is turned on, so that the steam flow control unit 37 of the steam generator 36 is energized, and the electromagnetic on-off valve that forms the steam flow control unit 37 is opened, so that steam can flow. . Therefore, the steam generated by the steam generator 36 is filled in the steam header 41a through the steam flow control unit 37 by the steam pressure, and sprayed onto the flooring floor F through the respective ejection nozzles 41b.

  As shown in FIG. 5, in the state where the detection means 31 detects the advance of the suction port body 14, the advance of the suction port body 14 is further continued, so that it is wetted by the steam ejection from the steam ejection portion 41. The flooring floor surface F is wiped together with dust on the flooring floor surface F by a second wiping member 46 disposed on the rear side of the suction port 26. By such cleaning with water wiping, fine dust such as sand particles can be wiped away without leaving behind. In the above-described advancement, the first wiping member 45 and the third wiping member 47 both wipe the flooring floor F dry.

  When the suction port body 14 is advanced as described above, a force that presses the suction port body 14 against the floor surface via the extension pipe 18 acts. For this reason, it is preferable that the flooring floor F can be wiped with water when moving forward, because the effect of wiping the floor is increased, so that the wiping effect of sand particles and the like is large.

  In addition, when the suction port body 14 that has been moved forward is pulled back toward the user's body and then retracted, the detection roller 32 is brought into contact with the flooring floor F from the state shown in FIG. Since the rotation rotates clockwise, the convex portion 32a of the detection roller 32 does not press the operation lever 33a of the detection switch 33, and the operation lever 33a receiving a biasing force by a spring (not shown) maintains contact with the detection roller 32. Follow as you do. Therefore, as shown in FIG. 6, the state in which the contact 33b of the detection switch 33 pushes the operating lever 33a beyond a predetermined amount is released, and the detection switch 33 is turned off.

  As a result, the energization of the steam flow control unit 37 of the steam generator 36 is cut off, the electromagnetic on-off valve forming the steam flow control unit 37 is closed, and the steam cannot flow. Therefore, the steam generated by the steam generator 36 is not supplied to the steam ejection part 41 through the steam flow control part 37, so that the steam ejection from each ejection nozzle 41b to the flooring floor F is stopped.

  As shown in FIG. 6, in the state in which the detection means 31 detects the retraction of the suction port body 14, the retraction of the suction port body 14 is further continued, so that the flooring floor surface wiped with water as described above is used. F is dry wiped by the first wiping member 45 disposed on the front side of the suction port 26 and the second wiping member 46 disposed on the rear side of the suction port 26. Thus, since the flooring F can be wiped and cleaned, there is no need to dry and wipe after cleaning.

  As described above, the flooring surface F is automatically wiped when the suction port body 14 moves forward, without requiring a special switching operation other than the normal cleaning behavior in which the user reciprocates the suction port body 14. Thus, the flooring surface F that has become wet can be wiped dry when the suction port 14 is retracted. In the case of water wiping when moving forward and dry wiping when moving backward, dust is sucked in through the suction port 26, so that dust is sandwiched between the wiping members 45 to 47 and the flooring floor surface F, and the flooring surface F becomes It can also be prevented from being damaged. In addition, the magnitude | size of the dust absorption force in this case was recognized by the user by controlling the rotation speed of the electric blower 15 via the motor driver 51 shown in FIG. 7 according to the operation command by the operation switch 19a. It can be adapted to the cleaning situation. The motor driver 51 is built in the cleaner body 12.

  In the embodiment, the steam switch 19b can be turned on and used in a state where the operation switch 19a of the operation panel 19 is turned off. In this case, although the dust suction accompanying the operation of the electric blower 15 is not performed, the control of the generated steam flow (stopping the outflow of steam) is automatically performed by the forward and backward movement of the suction port body 14, As the suction port body 14 is pushed and pulled (one reciprocation), the flooring F can be wiped and cleaned by alternately wiping the flooring F with water and dry wiping.

  In addition, when the steam switch 19b is turned off with the operation switch 19a of the operation panel 19 turned on as desired, the supply of steam from the steam generator 36 to the steam ejection part 41 is stopped. As described above, the dust on the flooring surface F can be sucked into the suction port 26 and cleaned while wiping the flooring surface F with the respective wiping members 45 to 47 in a state where no steam is ejected. That is, the flooring floor F can be cleaned in the same manner as cleaning using a normal suction port body that does not include the steam spraying means including the steam generating device 36 and the steam jetting portion 41.

  As described above, the vacuum cleaner 11 provided with the suction port body 14 performs cleaning by mere dust absorption without vapor ejection, cleaning with water wiping forward and dry drying with dust absorption and vapor ejection, and dust absorption. Since it is possible to arbitrarily select the form of wiping and cleaning with wiping water when moving forward and dry wiping when moving backward without steam ejection, it is preferable in that there are many options depending on the cleaning situation.

  The present invention is not limited to the one embodiment. For example, the water wiping and dry wiping on the flooring floor F performed in conjunction with the cleaning behavior of reciprocating the suction port body 14 is contrary to one embodiment, and the detection means 31 detects the retraction of the suction port body 14. In some cases, the steam flow control unit 37 controls the steam flow so that the steam generated by the steam generator 36 is supplied to the steam ejection unit 41, and the flooring surface F is wiped with water. When the forward movement of the body 14 is detected, the steam flow control unit 37 controls the steam flow so that the steam generated by the steam generator 36 is not supplied to the steam ejection unit 41 so that the flooring F can be wiped dry. May be. In this case, the first wiping member 45 is necessarily required, but the second wiping member 46 may be omitted.
