  The operation of the wet and dry electric vacuum cleaner A will be described. When the electric blower 406 is driven, the dust collecting fan 414 is rotated, and external air is sucked from the through hole 201 of the dust collecting can 21. Air sucked from the through hole 201 passes through the filter 401. At this time, when moisture is contained in the air, the moisture is accommodated in the dust collecting can 2. Further, dust contained in the air is collected by the filter 404 and accumulated in the dust collecting can 2. Air that has passed through the filter 404 and / or highly humid air is sucked into the fan case 409 from the suction hole 4091 of the fan case 409 that communicates with the through hole 4051 of the support frame 405.

  The air that has flowed into the fan case 409 is discharged from the discharge holes 4092 formed in the side periphery of the fan case 409 and flows into the exhaust passage 417. The air that has flowed into the exhaust passage 417 flows through the exhaust passage 417, and a part of the air is discharged to the outside through the exhaust port 428. Further, the remaining air flows into the overhanging portion 425 through the inflow hole 4251 and is discharged to the outside through the exhaust hole 4252 formed in the overhanging portion 425.

On the other hand, when the electric blower 406 is driven, the cooling fan 413 is also driven. When the cooling fan 413 is driven, the air dried from the air inlet 431 is sucked. The air taken in from the air inlet 431 passes through the throttle portion 429, passes through the air intake hole 4081, and flows into the electric blower 406. The inside of the electric blower 406 generates heat by driving, and is cooled by the inflow of air. The air that has cooled the electric blower 406 flows into the cooling flow path 416 through the exhaust holes 4082 formed in the side periphery of the motor frame 48. Since the cooling flow path 416 passes through a part of the upper portion of the pump holder 422, the auxiliary devices of the shampoo pump 418 are also cooled when air passes through the cooling flow path 416.

A plurality of embodiments of a shampoo tank and a method for attaching the shampoo tank will be described with reference to the drawings. 13 is a side view when the shampoo tank of the wet / dry vacuum cleaner shown in FIG. 1 is attached and detached, and FIG. 14 is a side view when the wet / dry vacuum cleaner shown in FIG. 15 is a rear view when the wet and dry vacuum cleaner shown in FIG. 1 falls to the side.

  As shown in FIG. 13, the lower portion of the shampoo tank 3 is disposed between the pair of support columns 111, and the lower portion is moved downward along the support columns 111. As a result, the shampoo tank 3 is attached in a regulated state, with the front of the lower surface being the dust collecting can 2 and the both sides being the struts 111. In addition, the distance between the support | pillar parts 111 of the handle | steering-wheel 11 is formed in the length of the grade which the side part of the shampoo tank 3 is guided when attaching or detaching the shampoo tank 3. FIG. Thereby, the shampoo tank 3 is easily attached to the tank attaching part 105 of the base part 1.

  The lower surface of the shampoo tank 3 is inserted into the tank mounting portion 105 of the pedestal portion 1, and the tank upper 302 is moved so as to be positioned below the overhanging portion 425 of the device case portion 4. At this time, the convex joint 426 is in a state where the restricting portion 4262 is lifted and the tubular portion 4261 is moved upward. The shampoo tank 3 is attached in a state where the tubular portion 426 is moved upward, so that the tubular portion 426 is prevented from interfering with the tank upper 302 of the shampoo tank 3, and the shampoo tank 3 is easily and smoothly attached to the tank mounting portion. 105 can be inserted and arranged. Thereby, when attaching the shampoo tank 3 which is a heavy article with which the washing | cleaning liquid was filled, it can suppress that the tank upper 302 contacts the tubular part 426 and the tubular part 426 is damaged.

  Then, after the shampoo tank 3 is inserted into the tank mounting portion 105, the force acting on the regulating portion 4262 is removed. As a result, the tubular portion 426 moves downward due to the elastic force of the coil spring 427, and the convex joint 426 is connected to the concave joint 304 formed in the tank upper 302 in a watertight manner.

  Since the convex joint 426 moves downward and engages with the concave joint 304, the convex joint 426 is shifted and inserted into the tank mounting portion 105 of the shampoo tank 3, and the central axes of the convex joint 426 and the concave joint 304 are shifted. The tubular portion 4261 of the convex joint 426 contacts the mortar-shaped portion 3041 of the concave joint 304. When the annular portion 4261 of the convex joint 426 moves downward, the mortar-shaped portion 3041 is pushed, the shampoo tank 3 moves, and the convex joint 426 and the concave joint 304 are connected in a watertight manner.

  As shown in FIG. 14, when the shampoo tank 3 is attached to the tank attachment portion 105 of the pedestal portion 1, a line (indicated by L <b> 1 in FIG. 14) connecting the tip of the step base 106 and the connecting portion 112 of the handle 11. It is formed so that there is no protruding part. Even when the wet / dry vacuum cleaner A configured in this manner falls backward, the shampoo tank 3 can be prevented from being directly hit by the floor. Further, as shown in FIG. 15, even when the wet and dry vacuum cleaner A falls sideways or obliquely rearward, the support column 111 or the connecting portion 112 of the handle 11 first comes into contact with the floor surface, and the shampoo tank It is possible to suppress 3 from being directly hit by the floor.

  The wet and dry electric vacuum cleaner A is increased in weight by itself and by the weight of solid and / or liquid waste sucked into the dust can 2. When the wet / dry vacuum cleaner falls down, the shampoo tank 3 is hit directly on the floor, and when the wet / dry vacuum cleaner A is laid underneath, there is a high possibility that the shampoo tank 3 will be damaged. Even if the wet and dry vacuum cleaner A falls down, the shampoo tank 3 does not hit the floor surface directly, so that the shampoo tank 3 can be prevented from being damaged. Further, even when the wet / dry vacuum cleaner A falls down, the shampoo tank 3 can be prevented from being damaged, so that the shampoo tank 3 can be formed of a thin member, and the shampoo tank 3 can be reduced in weight. Therefore, the labor for attaching the shampoo tank 3 to the pedestal portion 1 can be reduced. Further, the material for manufacturing the shampoo tank 3 can be reduced, and energy saving can be achieved accordingly.

  Next, a different example of a method for engaging the device case portion and the shampoo tank will be described with reference to the drawings. 16 is a perspective view of another example of the wet and dry vacuum cleaner according to the present invention, FIG. 17 is a plan view of the wet and dry vacuum cleaner shown in FIG. 16, and FIG. 18 is a shampoo tank and equipment of FIG. It is sectional drawing to which the engaging part with the case part was expanded. The wet and dry vacuum cleaner B shown in FIG. 16 has the same structure as the dry and wet vacuum cleaner A except that the overhanging portion is different, and substantially the same parts are denoted by the same reference numerals.

  The wet and dry electric vacuum cleaner B has an apparatus case portion 6 including an overhang portion 625 instead of the overhang portion 425. In the device case portion 6, guide members 635 are formed on the left and right sides outside the case lower 602. The guide member 635 includes a through hole 636 extending in the vertical direction. A rib 637 is formed on the outside of the overhanging portion 625, and the overhanging portion 625 is slidably supported by the case lower 602 by passing the rib 635 through the through hole 636. A coil spring 638 that is an elastic member is provided between the lower surface of the overhang portion 627 and the case lower 602. By providing the coil spring 638, the overhang portion 625 is biased upward.

  A convex joint 626 is attached to the overhang portion 625. The convex joint 626 is fixed to the projecting portion 625, and a tubular portion 6261 protrudes downward. As shown in FIG. 18, an engaging claw 639 that extends downward and bends forward is formed at the rear end of the overhang 625. On the other hand, a sliding claw 307 is formed at the rear of the tank upper 302 of the shampoo tank 3 so as to be slidable in the front-rear direction and biased rearward and engageable with the engaging claw 639. Yes.

  As shown in FIG. 18, the shampoo tank 3 can be inserted into the tank mounting portion 105 of the pedestal portion 1 without being obstructed by the convex joint 626 when the overhang portion 625 is disposed at the uppermost portion. When the overhanging portion 625 is moved downward with the shampoo tank 3 attached to the tank attaching portion 105, the tubular portion 6261 of the convex joint 626 is connected to the concave joint 304 of the shampoo tank 3 in a watertight manner. At this time, the coil spring 638 is compressed, and the engaging claw 639 and the sliding claw 307 are engaged. Thereby, the overhang | projection part 625 is suppressed to slide upwards.

  Even if the shampoo tank 3 is arranged so as to be shifted with respect to the tank mounting portion 105 of the pedestal portion 1 and the central axes of the convex joint 626 and the concave joint 304 are shifted, the tubular portion 6261 of the convex joint 626 is a mortar shape of the concave joint 304. Press the part formed on. As a result, the shampoo tank 3 is displaced, and the convex joint 626 and the concave joint 304 are accurately connected.

  When the sliding claw 307 is pushed and the engagement with the engagement claw 639 is disengaged, the overhanging portion 626 moves upward with a force restored by the coil spring 638, and the engagement between the convex joint 626 and the concave joint 304 is performed. Comes off. When the overhanging portion 625 is moved upward, the tubular portion 6261 is retracted upward.

  As described above, since the tubular portion 6261 is retracted by the overhanging portion 625 moving upward, the tip of the tubular portion 6261 does not get in the way when the shampoo tank 3 is attached or detached. Thereby, the insertion arrangement | positioning to the tank attaching part 105 of the shampoo tank 3 is easy. Since the overhang portion 625 always moves upward due to the force of the coil spring 638, the overhang portion 625 does not have to be operated when the shampoo tank 3 is inserted into the tank mounting portion 105. As a result, the shampoo tank 3 can be stably and smoothly inserted and arranged in the tank mounting portion 105 with both hands.

  Next, still another example of a method for engaging the device case portion and the shampoo tank will be described with reference to the drawings. FIG. 19 is an enlarged cross-sectional view before the shampoo tank is engaged with the equipment case of the wet / dry vacuum cleaner according to the present invention, and FIG. 20 shows the shampoo tank in the equipment case of the wet / dry vacuum cleaner shown in FIG. It is an expanded sectional view of the state which engaged. A wet / dry vacuum cleaner C shown in FIG. 19 has the same configuration as the wet / dry vacuum cleaner A shown in FIG. 1 and the like except that the shampoo tank 7 is different, and substantially the same parts are denoted by the same reference numerals. is there.

  As shown in FIGS. 19 and 20, the shampoo tank 7 of the wet and dry electric vacuum cleaner C is connected to the upper part of the tank upper 702 so as to be slidable up and down and to the rear part of the tank lower 701. It has a handle portion 306, a coil spring 708 that is an elastic member that urges the concave joint 704 upward, and a push lever 709 that is connected to the concave joint 704 and disposed on the upper portion of the handle portion 306. .

  When the push lever 709 is pushed downward, the concave spring 708 moves downward while the coil spring 708 is compressed. At this time, the concave joint 704 and the convex joint 426 are not engaged. Thereby, the tank upper 702 is formed with a notch for preventing the convex joint 426 from contacting when the shampoo tank 7 is attached. Thus, when the shampoo tank 7 is attached / detached, the tank upper 702 and the concave joint 704 do not contact the convex joint 426 and can be attached / detached smoothly and easily to / from the tank attaching portion 105. Further, when the downward force acting on the push lever 709 is removed while the shampoo tank 7 is inserted into the tank mounting portion 105, the concave joint 704 is pushed by the force that the coil spring 708 tries to restore. Move upward. As a result, the concave joint 704 is connected to the convex joint 426.

  Normally, when the user holds the handle portion 306, the thumb is at the top. The push lever 709 can be operated with the thumb, and the user can easily insert the shampoo tank 7 into the tank mounting portion 105 with one hand. Further, when the shampoo tank 7 is heavy, the shampoo tank 7 can be supported with the other hand and held, so that the shampoo tank 7 can be stably inserted into the tank mounting portion 105. .

  Next, still another example of a method for engaging the device case portion and the shampoo tank will be described with reference to the drawings. 21 is an enlarged cross-sectional view before the shampoo tank is engaged with the device case of the wet / dry vacuum cleaner according to the present invention, and FIG. 22 is the shampoo tank in the device case of the wet / dry vacuum cleaner shown in FIG. It is an expanded sectional view of the state which engaged. The wet / dry vacuum cleaner D shown in FIG. 21 and the like has the same configuration as the wet / dry vacuum cleaner A shown in FIG. 1 except that the step 120 of the pedestal portion 12 is different. Is attached. Although the shampoo tanks have different lengths, the configuration is the same, so that the description will be made using the same reference numerals.

  The step 120 of the wet / dry electric vacuum cleaner D is rotatably supported at the middle portion, and is formed so that the front portion 121 is raised when the rear portion 122 is lowered. The step 120 shown in FIG. 21 is locked when the rear portion 122 is stepped on at a predetermined angle with respect to the horizontal plane, and is unlocked when stepped on again in that state. Is attached.

  As shown in FIG. 21, the step 120 in the unlocked state has a front portion 121 disposed in the tank mounting portion 105, and the main body can be horizontal. In this state, the shampoo tank 3 is inserted into the tank mounting portion 105. When the shampoo tank 3 is inserted and arranged in the tank mounting part 105, the upper part of the front part 121 of the step 120 is placed in contact with the lower surface 300 of the shampoo tank 3. And the front part 121 is lifted by pushing down the rear part 122 (usually by stepping). As a result, the shampoo tank 3 is lifted, the tank upper 302 is externally fitted to the overhanging portion 425 of the device case portion 4, and the concave joint 304 formed on the tank upper 302 is the convex joint 426 of the device case portion 4. Is engaged. According to this configuration, since the user can hold the shampoo tank 3 with both hands when the shampoo tank 3 is attached, the shampoo tank 3 can be attached stably and easily.

  In the wet and dry electric vacuum cleaner, the cleaning liquid stored in the shampoo tank is sprayed on the cleaning target parts such as the floor and the carpet to raise the dirt, and then the cleaning liquid is sucked together with the dirt to perform cleaning. Usually, the floor material often changes as the room changes. If the floor material is different, the cleaning solution must be changed and it is inefficient to change the shampoo tank each time. FIG. 23 is a cross-sectional view of another example of a shampoo tank.

  As shown in FIG. 23, the shampoo tank 31 has a first storage portion 311 and a second storage portion 312 inside, and each is an independent region. Suction hoses 313 and 314 are inserted in the respective independent regions. A bifurcated hose 315 is attached to the concave joint 304 of the shampoo tank 31, and the bifurcated hose 315 is connected to the switching valve 316. Suction hoses 313 and 314 are also attached to the switching valve 316. Further, an injection port 317 for injecting the cleaning liquid into the first storage unit 311 and an injection port 318 for injecting the cleaning liquid into the second storage unit 312 are provided.

  The switching valve is connected to the suction hose 313 and the bifurcated hose 315 inserted in the first storage unit 311 in the first state (the state shown in FIG. 23), and the cleaning liquid stored in the first storage unit 311 is Sucked up and sprayed on the floor. Further, in the second state in which the switching valve 316 is turned 90 degrees from the first state, the suction hose 314 inserted into the second accommodating portion 312 is connected to the bifurcated hose 315 and accommodated in the second collecting portion 312. The cleaning liquid is sucked up and sprayed on the floor. As described above, different types of cleaning liquids can be selected by simply switching the switching valve 316 between the two types of cleaning liquids. Thereby, even when cleaning floors of different materials, it is not necessary to replace the shampoo tank each time, and the work efficiency is improved accordingly.

In addition, the switching valve 315 can illustrate what can be switched by twisting the knob formed in the outer surface of the shampoo tank 31. Moreover, it may not be switched by rotation but may be switched by slide. In the above example, the tank is divided into two regions. However, the present invention is not limited to this and may be further divided into a large number of regions. Examples of the two types of cleaning liquids include shampoo liquid and water.
(How to attach the dust can to the pedestal)
In a dry / wet vacuum cleaner, when discharging solid or liquid waste accumulated in the dust can, remove the dust can from the pedestal, turn the dust can over, and collect in the dust can. Dispose of solid waste and / or liquid waste. It is preferable that the dust collecting can be firmly held by the pedestal when cleaning with a wet and dry electric vacuum cleaner, and easily removed from the pedestal when discarding filth collected inside. Therefore, a preferred method of attaching the dust can to the pedestal will be described with reference to the drawings.

  24 is a front view of the wet / dry vacuum cleaner with the dust can held therein, and FIG. 25 is a side sectional view of the dry / wet vacuum cleaner shown in FIG. 26 is a side sectional view showing a state where the dust collecting can is removed from the pedestal portion. Note that the wet and dry electric vacuum cleaner E shown in FIG. 24 has a dry and wet electric appliance shown in FIG. 1 and the like except that a protrusion 211 is formed on the front portion of the dust collector 21 and a clamp 131 is formed on the front portion of the pedestal portion 13. It is the same structure as the vacuum cleaner A, and the same code | symbol is attached | subjected to the substantially same part.

  As shown in FIGS. 24 and 25, the clamp 131 includes a clamp hook 132 that rotates around the shaft 130 so as to fall forward, and a spring 133 that is an elastic member that biases the clamp hook 132. Yes. The clamp hook 132 includes an engagement recess 424 that engages with a protrusion 211 formed on the front portion of the dust collecting can 21. The clamp hook 132 is biased to rotate backward about the shaft 130 by the elastic force of the spring 133.

  As shown in FIG. 25, the protrusion 211 provided at the front portion of the dust collecting can 21 is provided at the lower portion and is inclined so as to be separated upward, and the upper portion is provided at the upper end at the upper end portion. It has the upright part 213 orthogonal to an outer surface. The inclined portion 212 and the upright portion 213 are integrally connected.

  As shown in FIG. 25, when the dust collection can 21 is held by the pedestal portion 13, the engagement recess 134 of the clamp hook 132 and the protrusion 211 of the dust collection can 21 are engaged. At this time, the upright portion 213 of the protrusion 211 is in contact with the inner wall of the engagement recess 134, and the engagement between the engagement recess 134 and the protrusion 211 is not released even when the dust collecting can 21 is lifted upward. Accordingly, the dust collection can 21 is firmly held by the pedestal portion 13 while cleaning is performed with the dust collection can 21 placed on the pedestal portion 42.

  Moreover, as shown in FIG. 26, the rear part of the clamp hook 132 moves obliquely upward by pushing the front part of the clamp hook 132 downward. Thereby, the engagement between the clamp hook 132 and the projection 211 is released, and a gap through which the projection 211 can pass is formed between the clamp hook 132 and the wall surface of the dust collecting can 21. In this state, the dust collection can 21 can be easily detached from the pedestal portion 13 by lifting the dust collection can 21. Moreover, when attaching the removed dust collecting can 21 to the base part 13, the dust collecting can 21 should just be arrange | positioned so that the processus | protrusion 211 and the clamp 131 may be lined up and down, and may be pushed in from upper direction. As the dust collecting can 21 moves downward, the clamp hook 132 is pushed by the inclined portion 212 of the projection 211 and pivots forward, and the engagement concave portion 134 of the clamp hook 132 and the projection 211 are engaged to collect dust. The can 21 is held on the pedestal portion 13.

  In the wet and dry electric vacuum cleaner, a suction hose (not shown) for sucking solid filth and liquid filth is attached to the front of the dust can 21. In the wet and dry electric vacuum cleaner, the cleaner 131 is often pulled by the suction hose during the cleaning operation, and the clamp 131 arranged at the front part hardly comes into contact with the obstacle, and the dust collecting can 21 is unexpectedly detached. Difficult to occur. Moreover, since it is a structure which rotates by pushing the front part of the clamp hook 132 downward, when a user removes the dust collecting can 21, the clamp 131 and the protrusion 21 are disengaged by stepping on the clamp hook 132. be able to. Thereby, since the user can remove the dust collecting can 21 in which the solid filth and the liquid filth are accumulated with both hands, the user can work easily and safely.

  Another example of a preferred method of attaching the dust collecting can to the pedestal will be described with reference to the drawings. FIG. 27 is a side view of the wet / dry vacuum cleaner with the dust can held therein, and FIG. 28 is a cross-sectional view of the wet / dry vacuum cleaner with only the dust can attached to the pedestal. FIG. 29 is a cross-sectional view seen from the front when the wet and dry vacuum cleaner in a state where only the dust collecting can is attached to the pedestal portion at the center, FIG. 30 is a side sectional view with the dust collecting can removed, and FIG. 31 is a front sectional side view with the dust collecting can removed. The wet and dry electric vacuum cleaner F has the same configuration as the wet and dry electric vacuum cleaner A shown in FIG. 1 and the like except for the protrusion 221 of the dust collector 22 and the clamp 141 of the pedestal portion 14, and is substantially the same. The parts are given the same reference numerals.

  As shown in FIGS. 27, 28, and 29, the clamp 141 is disposed on the front portion and both side portions of the pedestal portion 14. Further, projections 221 that are engaged with the clamps 141 are formed on the front and both sides of the dust collection can 22. The protrusion 221 is a protrusion protruding outside. The projections 221 on both sides of the dust collection can 22 are arranged at positions where the central angle about the central axis of the dust collection can 22 is 90 degrees from the projection 221 arranged at the front.

  As shown in FIGS. 30 and 31, the clamp 141 is configured so that the base 142 protrudes upward from the pedestal portion 14 so as not to come into contact with the dust collecting can 22, and the base 142 can be rotated on the base 142. A link 143 connected and an engagement member 144 connected to the tip of the link 143 so as to be rotatable are provided. The engaging member 144 has a claw portion 145 formed to be bent inward at the tip. As shown in FIGS. 28 and 29, the claw portion 145 is engaged with the protrusion 221 of the dust collecting can 22.

  The claw portion 435 is engaged with the protrusion 221 of the dust collecting can 22 and the lower portion of the engaging member 144 is pushed toward the dust collecting can 22 to be fixed. At this time, the engaging member 144 rotates around the engaging portion between the claw portion 145 and the protrusion 221, and the link 143 rotates around the connecting portion with the base portion 142. The connection portion of the engagement member 144 with the link 143 is rotated when the engagement portion between the claw portion 145 and the projection 221 is rotated, and when the rotation portion is rotated with respect to the connection portion between the link 143 and the base portion 142. The trajectory is different. The arrival position is closer when the link 143 and the base 142 are rotated around the connecting portion. The engagement member 144 is pulled by the difference in the trajectory, and the link 4143 is compressed. Due to the tensile force acting on the engaging member 144, the protrusion 221 of the dust collecting can 22 is firmly held by the engaging member 144.

Thus, by providing the clamps 141 for fixing the dust collection can 22 and the pedestal portion 14 at three locations, the dust collection can 22 can be held on the pedestal portion 14 more stably. In this example, the side clamp is disposed so that the center angle of the center axis of the dust collector can be 90 degrees with respect to the front clamp. However, the present invention is not limited to this. is not. However, in consideration of stable holding, work convenience, and the like, it is preferable that they are formed at symmetrical positions around the front clamp. Further, the number of clamps is not limited to three, and it is only necessary to have a number of clamps that can hold the dust collecting can firmly.
(Other examples of dust cans)
The dust collector can be lifted from the pedestal when the solid waste and / or liquid waste collected inside is discarded. At this time, the user needs a clue to lift. FIG. 32 is a side view of an example of the dust collecting can, and FIG. 33 is a side view and a plan view of another example of the dust collecting can.

  As shown in FIG. 32, the dust collecting can 22 may be provided with a gripping part 222 that rotates upward on the side surface and can move to the upper part of the opening. This gripping part 222 is rotated forward when the dust collecting can 22 is attached to the pedestal part, and does not interfere with the attachment of the shampoo tank or the device case part. Also, it doesn't protrude significantly, so it won't get in the way during cleaning. Then, by rotating upward, the dust collecting can 22 can be easily removed from the pedestal portion by lifting the grip portion 222.

  Moreover, as shown in FIG. 33, the loop-shaped holding | grip part 223 which can insert a finger into the side part of the dust collecting can 22 may be formed 1 each on either side. Since the grip portion 223 is formed on the left and right, the user can hold the dust collecting can 24 with both hands, and thus the dust collecting can 22 can be attached and detached easily and safely.

  The above description of the embodiment is for explaining the present invention, and should not be construed as limiting the invention described in the claims or reducing the scope thereof. It is needless to say that each part configuration of the present invention is not limited to the above embodiment, and various modifications can be made within the technical scope described in the claims.
