DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet / dry vacuum cleaner which supplements dust contained in a gas with water stored in a gas suction passage.

[0002]

2. Description of the Related Art Conventional wet / dry vacuum cleaners using water as a filter include a case in which water contained in a liquid storage case is supplemented with intake air containing dry dust and a liquid storage case. 2. Description of the Related Art There is a vacuum cleaner having a structure in which a case is emptied and water and liquid including wet dust are trapped in a liquid storage case. This type of vacuum cleaner has a water separator that separates heavy objects such as moisture from dust or air containing water trapped in the liquid storage case directly under the electric fan motor. And the height from the grounding wheel to the electric fan motor was high. In addition, since the electric fan motor is heavy and has a high center of gravity and is unstable because of its stability, the distance between the grounding wheels is large and the body is large and heavy. Therefore, where there is a step, or
It is inconvenient to carry and is not suitable for people with low physical strength, such as when using stairs in general homes on the ground floor, other floors such as upper floors, and when sucking a large amount of water and dust containing liquid, or Also, it is not suitable for sucking liquid waste (such as waste from sick people and infants).

[0003]

The conventional wet / dry vacuum cleaner as described above is provided directly under the electric fan motor.
Because a water separator is installed, it is a vertically long cylindrical type,
Since the heavy electric fan motor is provided on the liquid storage case, the center of gravity of the main body is high and unstable, which is why the electric fan motor was large and heavy. By operating the electric fan motor at a low position, the center of gravity is lowered, and it is small, lightweight, and has improved traveling operation performance and portability. A vacuum cleaner that can suck a large amount of liquid as well as dust without lowering the suction efficiency, and also can suck liquid contaminants (waste of sick people and infants) can be taken out easily. The purpose is to gain.

That is, reference numeral 9 denotes a fan fixing cover formed of a synthetic resin material, and its lower end is detachably connected to the lid 17 of the liquid storage case 23. The water separator E is accommodated in the fan fixing cover D. The water separator section E is shown in FIG.
As shown in FIG. 1, the pump 1 includes an impeller 1 and a water separator 14 rotated by the impeller 1. More specifically, an upper fan fixing plate 2, a lower fan fixing plate 3, and a fan side fixing tube 8 are provided inside the fan fixing cover 9.
The impeller 1 is installed so as to be able to rotate therein. 11 is a fan shaft and 12 is a bearing. As shown in FIGS. 3 and 6, the upper fan fixing plate 2 is provided with a fan exhaust port 7 in a part thereof.
, An exhaust hood 5 for exhausting air in a predetermined direction is provided. As the lower Juan fixing plate 3 shown in FIGS. 5 and 7, Yes and Juan inlet 6 is provided in a part, this
Fan intake hood (simply air intake ) near 6 for taking air from a predetermined direction in the vicinity of 6
4 ) are installed. FIG.
7A and 7B show the impeller 1 and the upper fan fixing plate 2 viewed from above, and FIGS. 7A and 7B show the impeller 1 and the lower fan fixing plate 3 viewed from below. It is.

The water separator 14 is provided at the lower end of the fan shaft 11. The water separator 14 has thin blades 14a radially arranged around the fan shaft 11, and is configured as shown in FIGS. The blade 14a is shown in FIGS.
As shown in (b), the inlet is oblique with the upper part at the front position and the lower part at the rear position with respect to the rotation direction, and the whole is conical from the upper part to the lower part and contains water and moisture. It is configured so that the dust flows down and shakes off. That is, the hood cover 13 and the lid 17 of the liquid storage case
Between the hood cover 13 and the fan fixing cover 9.
The penetration of moisture into the gaps is reduced. The flow of the intake air flows through the slit portion of the intake port 16 as shown in FIGS.
(B) As shown by the arrow in FIG.
, And is discharged from the exhaust port 35 of the electric fan motor through the impeller 1 as described above.

In the connection pipe F, one end of the connection pipe 27 is connected to the upper end of the electric fan motor cover 33 via a spring 31, and the other end is connected to the intake connection port 9 a at the upper end of the fan fixing cover 9. Things. That is, one end of the connection pipe 27 is always drawn into the electric fan motor cover 33 by the spring 31. The connection pipe 27 is pulled by the force of the spring 31 pulling one end.

Reference numeral 28 denotes a lid that also serves as a support for the connection pipe 27. Reference numeral 29 denotes a stopper when the connection pipe 27 is pulled in, and reference numeral 30 denotes a stopper when the connection pipe 27 is pulled out.

Next, the dust collecting operation of the wet / dry vacuum cleaner configured as described above will be described. That is, a dust collection hose (not shown) is connected to the suction inlet 20 and the electric fan motor 34 is driven. Electric fan motor 34
The air containing dust from the dust collection hose by the suction power of
As shown by an arrow in FIG. 20, the water 39 is introduced from the suction inlet 20 into the water 39 by the suction inlet pipe 22a. The dust is supplemented by the water 39. The air after the dust removal is discharged from the water separator section E through the connecting pipe section F, further through the electric fan motor section B, and from the exhaust port 35.

The air flow causes the impeller 1 to rotate, and at the same time, the water separator 14 to rotate. Water separator 14
Works to shake off water 39 scattered together with the air at the time of intake by centrifugal force so that the water 39 is not sucked into the electric fan motor 34.

(Embodiment 2) In the above description, the case of sucking air containing dust is described. However, liquid such as water or tea spilled on a floor or a table can be sucked. That is, the suction inlet 22 is
After removing a, the air inlet / branch 21 is inserted, the air inlet pipe 22a is inserted into the water inlet 22b, and the electric fan motor 34 is driven, whereby water or various liquids are sucked. The sucked water and liquid are separated by the water separator 14 and fall into the liquid storage case 23 . Therefore, no water or liquid is sucked into the electric fan motor 34. In addition, spilled water and tea etc
Although it is permissible to inject from the water 2, water or tea is not dust, so it does not matter if it does not pass through the water 39.
In this case, since the rotation of the fan is clockwise as viewed from above, the opening of the air inlet pipe 22a is open rightward, so that the inhaled dust collects clockwise to the outer peripheral portion. For this reason, hard dust is prevented from directly hitting the water separator 14.
The water inlet 22b and the air inlet 22 are vertically branched, and one of the water inlet 22b and the air inlet 22 is covered with the air inlet / branch 21 so that the air inlet 22 and the water inlet 22 are connected. It is configured to select the mouth 22b. By this selection, when foreign dust or liquid is sucked, dust can be efficiently collected by changing the lid of the intake introduction branch tap 21 in advance. The above-mentioned foreign substances are dust mainly composed of intake air, and one of them is intake mainly composed of liquid. Dry dust mainly composed of intake air is covered with the water intake introduction port 22b, and the intake intake port 22 is opened. Water level guide pin 2 in the state
The object can be achieved without any problem if the water is used by placing it in the liquid storage case 23 up to a water level reference scale ( not shown) (a position where the upper part of the opening of the intake inlet 22 is immersed in water). .

If water or liquid is to be sucked, the liquid storage case 23 may be emptied and used.
If it is desired to suck more liquid than the water level guide pin 24, the intake inlet 22 installed below the vertically divided inlet is covered, and if the water inlet 22b installed above is used, the water is introduced. The suction can be performed without lowering the suction efficiency up to a water level upper limit line (not shown) just before the separator 14 is submerged. The liquid storage case 23 is emptied and the water inlet 2
When the suction inlet 22 is used in a live state with the lid 2b covered, the water pressure increases from the water level guide pin 24 as the amount of water and liquid increases, the water pressure increases, and the suction inlet 22 is pressed to lower the suction efficiency. , The liquid storage case 23 from the intake inlet 22
The air discharged to the water becomes large, and the dust becomes wrapped in the air bubbles. The water and the liquid are scattered, and the scattered solids of the water and the liquid become large. And the result is that the rotation efficiency of the water separator 14 is poor, and the result as when the water inlet 22b is used cannot be obtained. As a result of the above, the water level guide pin 24
The original purpose can be achieved without using the water inlet 22b for the purpose of water absorption up to.

Next, the operation when the operation is completed will be described. First, the electric fan motor 34 is turned off, and the carrying handle 43 is opened. And a cover for fixing the fan
The connecting pipe 27 between the section D and the electric fan motor section B is pulled out against the spring 31. At this time, for fixing the fan
The connection pipe 27 is disconnected from the intake connection port 9a of the cover 9.
The drawn connection pipe 27 is rotated left or right by about 60 °. In this state, the fan fixing cover D in which the water separator E is built is removed. And the liquid storage case 23
Can be removed and the water 39 inside can be discarded.

When sucking liquid dirt (waste of a sick person or an infant), for example, as shown in FIG. 21, a plastic bag 23a matching the size of the liquid storage case 23 is inserted using a water inlet 22b. The water inlet 22b is attached to the inside of the liquid storage case 23 so as not to be blocked, and the lid 17 of the liquid storage case is closed while the end of the plastic bag is kept outside the liquid storage case 23, and the water separator section is opened. E is placed and the connection pipe 27 is connected. In this state, the electric fan motor 34 is operated, and when liquid contaminants are sucked into the suction inlet 20 from a hose (not shown) having a suction port at the tip, the liquid storage case 2
Since the dirt is put into the plastic bag 23a mounted in 3 and the cleaning is completed, the above setting is removed and the dirt can be taken out simply by taking out the plastic bag 23a. The liquid storage case 23 is transparent and has an airtight seal 19 attached to a contact point with the lid 17 of the liquid storage case at the upper part of the outer periphery. Since the upper limit scale of the liquid suction is provided, the amount of dust can be grasped from the outside so that the replacement time of water and dirt can be seen at a glance and it can be detached.

(Embodiment 3) Suction of dirt (waste of a sick person or an infant) has been described above. However, since the dirt is viscous, the suction inlet 20 of the liquid storage case 23 in FIG. The dirt which is branched into the mouth 22 and the water inlet 22b and which is bent and complicated and adheres thereto is not easily removed even when the dirt is washed. This is not hygienic, so suck
There are two water inlets 22b and two air inlets 22 in the inlet 20. Only one water inlet 22b is provided at one location on the upper part of the liquid storage case 23, and the water inlet not so bent.
22b is provided (see FIG. 21). The liquid storage case 23 is used empty without water, and a plastic bag 23a is mounted (see FIG. 21) . In this case, since the water level pin 24 is unnecessary, it is removed, and an upper limit reference scale is provided on the outer peripheral portion. A liquid storage case 23 dedicated to waste shown in FIG. 21 is provided as an accessory of the vacuum cleaner. Also, a hose ( not shown) having a suction port at the tip is prepared for filth only as needed. As described above, the vacuum cleaner can be used simply and hygienically by dividing the liquid storage case 23 into waste and waste.

(Embodiment 4) The impeller 1 is a fan which rotates by suction wind pressure for rotating the water separator 14 for splashing water and liquid at high speed and high torque.
4, 5, 6a, 6b, 7a, 7b. That is,
FIGS. 3, 4, and 5 are exploded views for easy understanding.
Has a body portion 1a, and the width of the blades is substantially the same in both the upper and lower portions, and the length is also the same. And the surface receiving the wind pressure is concavely curved so that it is difficult for the wind to escape. In the prototype, the number of blades of the impeller 1 is set to 14, but depending on the size of the fan, the number of blades may be increased or decreased. The number should be efficient. A pair of the impeller 1, the upper fan fixing plate 2, and the lower fan fixing plate 3 is used as a fan side fixing cylinder 8.
What is fixed inside (not shown) is a fan that rotates by suction wind pressure.

To the above fan, the electric fan motor 34
The wind pressure sucked from the fan impinges on the fan of the impeller 1 inclined at an angle θ from the fan intake port 6 and passes through the fan exhaust port 7 so as to push away the blade.
It is discharged from the outlet 35 of the electric fan motor 34 through the connection pipe 27 between the electric fan motor 34. The angle θ of the blades of the impeller 1 is the electric fan motor 34
Depending on the horsepower and the suction power, the angle may be set to an appropriate angle between 30 ° and 80 °.

In the course of the above, the most important configuration is the size of the fan intake port 6 and the fan exhaust port 7, and the lower fan is designed to concentrate the intake air pressure on only a few blades of the impeller 1.
Only one part of the fan fixing plate (hereinafter, also referred to as fan fixing plate) 3 has the fan intake port 6 opened (see FIG. 7B) .

The appropriate size of the intake port 6 depends on the horsepower of the electric fan motor 34, the magnitude of the suction power, and the oblique angle θ of the impeller 1, but in the case of a general household vacuum cleaner, It is thought that the size of the suction hose of the vacuum cleaner around the diameter does not significantly reduce the suction power of the electric fan motor 34 and the suction efficiency is good. The size of the fan exhaust port 7 is also substantially the same as the size of the fan inlet port 6 (see FIG. 6B), and its opening is located directly above the fan inlet port 6 and on a vertical line. In the embodiment, by shifting the position of the fan inlet 6 and Juan outlet 7, the rotational speed, air volume, torque, since changes come, by the work rate of the electric fan motor to be used, the intake port 6 and exhaust port 7 may be shifted, but basically, the intake port 6 and the exhaust port 7 are provided at positions where the intake air passes in a vertical direction perpendicular to the blades of the impeller 1.

In the case of a fan which rotates by applying suction air pressure to the blades of the impeller 1 as shown in FIG. 4, in a small size, the intake port 6 and the exhaust port 7 may be enlarged so as to apply more intake air pressure to the blades. In the case of a large-sized blade used in another field such as industrial use, the intake port 6 and the exhaust port 7 may be enlarged.

In short, the fan intake port 6 and the fan exhaust port 7 depend on the horsepower and suction power of the electric fan motor 34, the angle of the blades, and whether the fan is small or large or the target torque.
Will also change in size.

The shape of the openings of the fan intake port 6 and the fan exhaust port 7 is the same as that of the impeller in the plan view of the lower part of the impeller shown in FIG. 7 and the plan view of the upper part of the impeller shown in FIG. It is possible to efficiently apply the suction wind pressure to the blades of the fan impeller 1 of Juan. That is, the fan which is the opening
The intake port 6 and the fan exhaust port 7 have the same shape as the cross section of the blade at both the upper and lower portions of the blade (FIGS. 6 (b) and 7 (b)).
As a result, when the operation power supply unit ( not shown) of the electric fan motor 34 is operated, the intake wind pressure hits several blades of the impeller 1 from the fan intake port 6 and pushes the fan exhaust port 7 so that the blade is pushed away. pass. At this time, the impeller 1
Rotates. Since the above is continuous at high speed, a fan with high speed rotation and high torque has been completed. Juan shaft 11
Is made of stainless steel and has bearings attached to the bearings to withstand high-speed rotation.

(Embodiment 5) In this embodiment, an intake hood 4 is provided at an intake port 6 and an exhaust hood 5 is provided at an exhaust port 7. Particularly important is the intake hood 4, and an electric fan motor 34 is provided. the dust containing moisture by suction force of the clean air separated by the water separator 14 intake hood (simply Food
4 ) It was possible to intensively apply the air with good angle and wind pressure to the blades of the impeller 1 in a concentrated manner, resulting in even higher rotation speed and higher torque fan. As shown in FIG. 5, the shape of the hood 4 is provided so as to cover the fan intake port 6 in such a manner as to match a screen with a duct.
I have .

(Embodiment 6) Next, an intake hood cover
(Hereinafter referred to as a hood cover) Regarding 13, FIG.
This will be described with reference to FIGS. As shown in FIG. 9, the shape is cylindrical, and there are four intake inlets 13 a at the lower portion, and the air inlet 13 a is fixed to the fan shaft 11 with a hood cover mounting screw. It is only connected to the impeller 1 by the fan shaft 11 (see FIG. 2). Therefore, the power supply operation unit ( not shown) of the vacuum cleaner is operated, and the suction including the dust entering from the suction inlet 20 by the suction force of the electric fan motor 34 is supplied to the water 39 in the liquid storage case 23 through the suction inlet pipe 22a. The water is supplied to the hood cover 13, the hood 4, and the fan intake port through the intake port 16 of the water separator 14. 6, impeller 1, fan exhaust port 7, connection pipe 27
Through the outlet 35 of the electric fan motor 34. During this series of processes, the hood cover 13 rotates together with the impeller 1 at the same time as the intake air passes through the impeller 1.
Top cover 13, the impeller 1 and the water separator 14 is also a role to integrate also Fudoribu to depress the outside air sucked from outside air introduction hole 10 to be described later downward 40
Are provided at an oblique angle. In the prototype, there are three places at equal intervals, but it may be increased or decreased according to the size of the hood cover 13. Due to the effect of the hood rib 40, the side surface of the fan is fixed.
No liquid containing dust entered the impeller 1 through the gap 8a between the fixed cylinder 8 and the hood cover 13.

(Embodiment 7) Next, the water separator 14 will be described with reference to FIGS.
The intake air containing dust sucked by the suction force of the electric fan motor 34 is supplemented from the suction inlet 20 into the liquid storage case 23 by water 39 which has been put in advance. Splashes come in to push away the water 39 and splash it. If this is sucked by the electric fan motor 34 as it is, water droplets and dust mixed with the water droplets will be sucked together. Therefore, air and water droplets are separated by a water separator 14 using centrifugal separation.

The arrows in FIGS. 11, 12 and 13 show the flow of the intake port and the intake air, and since the rotation direction of the fan body is clockwise as viewed from directly above, the structure of the water separator 14 is also clockwise. is there. Fig. 13b is a plan view of the upper surface, and 16 openings having a rectangular shape and narrowing toward the center (see a sectional view of the upper surface of the separator in Fig. 13a) are radially arranged and circular. (See FIG. 13b. Top view of the separator.) The rotation direction is clockwise rotation when viewed from above, so that water including dust and liquid such as dust do not enter through the suction port.
Is opposite to the direction of rotation so that it is difficult to inhale air,
The upper part of the opening is open to the front position and the lower part is opened obliquely rearward to the rear position. As shown in FIG. The hood cover 13 and the liquid storage case 2
Intrusion of water and liquid including dust from the gap of the lid 17 of the third is reduced. In FIG. 13b, 16 inlets are provided, but this number may be increased or decreased depending on the size of the fan. Although the depth of the suction port changes depending on the width of the opening, a wall (see FIG. 13B) is formed.
So it repels airborne dust and, at the same time, dusty water,
In addition, water does not enter the impeller 1 because of the structure for repelling liquid.

(Embodiment 8) Hood cover 13 and liquid
A small hole for introducing outside air into the fan fixing cover 9, that is, outside air, because water and liquid containing a small amount of dust enter through the gap of the lid 17 of the storage case 23 and penetrate into the electric fan motor 34. The introduction hole 10 is opened. (See FIG. 2) This outside air introduction hole 10 is not opened several equidistantly
You. In the implementation of the prototype, four are opened at equal intervals, but depending on the horsepower of the electric fan motor 34 and the magnitude of the power, the size and position of the outside air introduction hole 10 may be changed or increased or decreased. Opening the outside air introduction hole 10 is a loss of suction efficiency. However, since the hole is small, only a small amount of outside air is sucked, and there is no problem in the performance of the main body in general cleaning. (If the intake port is blocked in a suction experiment or the like, the suction force from the outside air introduction hole increases and the suction loss increases.) This small amount of outside air is generated by the hood rib 40 provided on the hood cover 13 described above. There is also work, Juan side fixed
Since the outside air is pushed out from the gap 8a between the fixed cylinder 8 (fan fixing cover 9) and the hood cover 13 to the lower liquid storage case 23, the wind pressure of the outside air causes the lid of the hood cover 13 and the liquid storage case 23 (hereinafter simply referred to as the lid). With the lid of the liquid storage case
No water or liquid containing dust entered the electric fan motor 34 through the gap 17.

(Embodiment 9) Next, the lid 17 of the liquid storage case will be described with reference to FIGS. The lid 17 is a lid for placing the water separator section D on the liquid storage case 23 for use, and as shown in FIG. It is made of transparent synthetic resin to see the dust condition. Also,
The dust 39 is simply placed on the liquid storage case 23 so that it can be removed to discard the dusted water 39, and since it does not use any fasteners, it can be easily attached and removed. There is a circular hole in the center where the water separator 14 enters, and it is easy to mount when the water separator part D is placed. There is a circular protrusion 17a on the outer periphery of the hole so as not to shift, and the water separator part D There is a hermetic seal 18 that keeps the contacts airtight.

(Embodiment 10) Next, the connection pipe 27 will be described. That is, the connecting pipe 27 of the water separator portion D Hua
The connection cover 9 is connected to the intake port of the electric fan motor 34. Water separator part D and lid 1 of liquid storage case 23

It is configured to be able to move. When pulled out as described above, the connection with the fan fixing cover 9 is disconnected, and the water separating unit D, the lid 17 of the liquid storage case, and the liquid storage case 23 may be taken out of the chassis 25 by turning left or right. . When setting, the liquid storage case 23 is placed on the chassis 25, the lid 17 is placed, the water separator section D is placed thereon, and the connecting pipe 27 which is moving to the left or right is lifted, and set just above the water separator section D. Then, the connecting pipe 27 is lowered by the force of the spring 31 and is brought into close contact with the water separator D. And an operation power supply (shown
When the electric fan motor 34 is operated by
The inside of the liquid storage case 23 is airtight due to a vacuum state.
The seals 18, 19 and 26 are airtight and press-fitted, so that no air flows in from the outside. Then, air is sucked from an intake hose (not shown), and the following results are obtained in the above embodiment.

When the electric fan motor 34 is operated to inhale dry dust without putting the water 39 into the liquid storage case 23, or when the storage case 23 is emptied when mainly sucking liquid, the dry dust is A filter 32 is attached to the upper part of the electric fan motor 34 in order to supplement the floating dust when passing through the separator 14. (Dust is not too much worry gather the outer periphery of the case at the rotational wind pressure of right intake air introduction pipe 22a and the water separator 14) electric fan motor
Open the lid 28 of the -34 with a hinge, and close it with a stopper when closing.
I am trying to do it.

(Embodiment 11) A hand-held handle 43 (FIGS. 18 and 1) which is convenient to carry
9) is hinged to the chassis 25 so as to sandwich the connection pipe 27 from both sides. A permanent magnet is used partially for the handle 43 in FIG.
Attachment / detachment angle of the handle 43 for attachment / detachment is about 60 to 120 degrees, and it has an inverted U-shape. Each has a pocket 43a, and contains attachments such as a liquid suction port. It is a structure that can be done.

(Embodiment 12) Although relatively heavy dust contained in the intake air comes into contact with water and is likely to be caught in the water, light airborne dust floats in the air bubbles of the intake air and hardly comes into contact with water. Therefore, especially when a large amount of powdery dry dust is sucked at a time, the water 3 contained in the liquid storage case 23 in a solid state is
9, the suspended dust scattered in the liquid storage case 23 is easily separated from the water separator 14 because it easily floats on the water and hardly dissolves in the water.
May slip through. For this reason, the floating dust holding plate 41 is previously attached to the liquid storage case 23 and the lid 17 of the liquid storage case.
By mounting between them, it is possible to suppress the scattering of dry dust entering from the intake inlet pipe 22a, so that the contact efficiency with water can be increased, it is easy to dissolve in water, and it is particularly effective in collecting powdery dry dust. is there. (See FIG. 23)

The floating dust holding plate 41 has a concave shape, a dish shape, and an intake port 42. Intake inlet pipe 22a
Is opened rightward, the suction port 42 of the floating dust holding plate 41 is located diagonally rearward and upper side of the opening of the suction inlet pipe 22a, and when the dust has completed one round in the liquid storage case 23, the floating dust The liquid storage case 23 and a part of the floating dust holding plate 41 are marked so that the suction port of the holding plate 41 comes. The floating dust holding plate 41 and the liquid storage case 2
It is desirable to form irregularities on a part of 3 so that it cannot be attached to places other than irregularities. The material is transparent made of synthetic resin and is detachable so that it can be attached as required.

(Embodiment 13) FIG. 24 shows a case where the performance of the vacuum cleaner described above is not changed, but the liquid storage case 23 is enlarged for business dedicated to water absorption, and is convenient for drainage and waste liquid of sucked liquid. A faucet 43 is attached.

(Embodiment 14) FIGS. 27, 28 and 29
Is connected to the connection pipe on the intake port side of the electric fan motor 34 and the fan.
FIG. 27 is a partial view of a joint portion for connecting the unfixing cover 9 side, that is, a connecting pipe of the water separation device. The water separation device of FIG. 26 is set on the lid 17 of the liquid storage case, and the electric fan motor 34 Juan fixed to the connecting pipe extending from the intake port
The connection pipes extending from the cover 9 may be fitted together and the connection pipe 44 may be slid and fixed . Although the gap of the sliding portion of the joining tube 44 is an airtight gap that cannot be confirmed with the naked eye, it can slide smoothly.

The connection pipe on the side of the electric fan motor 34 and the fan
The cut portion of the joint portion of the connection pipe on the side of the unfixing cover 9 is formed at an oblique angle when viewed from above (see FIGS. 28 and 29). The water separator shown in FIG. 26 is set on the lid 17 of the liquid storage case. At this time, if the joints are suddenly joined, it is difficult to join the joints because there are few gaps in the joints. Therefore, the joints are shifted in advance and the water separator is securely set on the lid 17 of the liquid storage case, and then the water separator is turned. When it is moved to match the connection pipe on the electric fan motor 34 side, the joining can be performed smoothly.

The oblique angle in FIG. 28 can be either left or right. However, in the case of a cover with a thread, etc., it is generally closed by turning it clockwise, so from the viewpoint of the sense, as shown in FIG. It is considered good to have an oblique angle so that it can be joined clockwise.

In FIG. 27, a chain 46, a string, a wire, or the like may be attached to the fan motor 34 so that the joint tube 44 does not fall off.

(Embodiment 15) Lid 1 of liquid storage case
The seventh embodiment has been described with reference to FIGS. 14, 15, and 16 in the ninth embodiment, but the lid 17 as shown in FIGS. 30, 31, and 32 is more effective. That is, the lid 17 is a lid for placing the water separator section D on the liquid storage case 23 for use, and as shown in FIG. It is made of transparent synthetic resin so that the dish can be seen down and the dust removal condition inside can be seen. In addition, since the water 39 is merely placed on the liquid storage case 23 so that it can be easily removed when the dirty water 39 is dusted and discarded, and a stopper is not used, the desorption is easy. (During cleaning, it does not come off due to the suction force of the electric fan motor 34 even if the stopper is not used.)

Embodiment 15 (The entire structure is shown in FIG.
5), there is a circular hole at the center of the lid 17 or near the electric fan motor 34 , in which the water separator 14 is inserted. Seal 17 is provided on the outer periphery of the hole to keep the contact point with the water separator D airtight.
There is. (See FIGS. 30, 31, and 32) On the lower surface of the lid 17 , a ring-shaped projection 50 is provided so as to surround the water separator 14.
As shown in FIG. 41, the water 39 pushed away by the force of the air entering from the intake inlet pipe 22a hits the bottom of the upper water separator 14 by the water blow-up plate 52, and the rotation of the water separator 14 Are scattered radially obliquely upward to form a water curtain, and most of the water 39 that has formed the water curtain falls along the edge of the liquid storage case 23 along the lid 17 of the liquid storage case.

In order to efficiently use the water 39 that has made the water curtain , a lower projection ring 50 is provided below the lid 17 of the liquid storage case. This is effective for narrowing the area of water 39 scattered radially by the water separator 14 to produce a dense water curtain. The structure of the ring-shaped projections 50 makes the inner wall and the water 39 drop into wavy irregularities, so that the water 39 flows down like a shower while dispersing the water 39 on average, so that the floating dust is efficiently absorbed. . (See FIGS. 30, 31, and 32)

Although the lid 17 has the above structure, the hole into which the water separator 14 enters is not located at the center, but is provided at the electric fan motor 3.
It was set near four. The reason is that the intake pipe 2
Although bubbles come out from 2a, fine dust in the popped bubbles is kept away from the intake port 16 of the water separator 14, and the water curtain can be made effective. In addition, the connecting pipe of the water separator can be shortened and the water separator can be compact, and the water separator can be easily set on the lid 17 of the liquid storage case. Then, a part of the contact point with the liquid storage case 23 is marked with unevenness so that it can be installed only at the installation location. By doing so, the joining distance between the connecting pipes is perfectly matched.

(Embodiment 16) The water separator 14 is the one shown in FIGS.
However, the configuration shown in FIGS. 33, 34, and 35 is more effective. That is, the suction including the dust sucked by the suction force of the electric fan motor 34 is supplemented from the suction inlet 20 into the liquid storage case 23 by the water 39 previously placed. The water 39 is pushed away, and the water splashes. If the splash is sucked by the suction force of the electric fan motor 34 as it is, water droplets and dust mixed with the water droplets are also sucked together. Therefore, air and water 39 are separated by the water separator 14 using centrifugal separation.

FIG. 33 is a sectional view of the water separator 14 .
As can be seen from FIG. 34 and FIG. 35 , the entire configuration of the blade portions 14a and 14b of the intake port 16 is conical or cylindrical, and since the rotation direction of the fan is clockwise as viewed from directly above, the water separator 1
The structure of 4 is also for clockwise use. Blade 14 of intake port 16
A and 14b become narrower toward the center and spiral radially from the center, and several long portions 14b are provided evenly inside the blade 14a of the intake port 16. This means that when water is used by pouring it above the water level mark of the liquid storage case 23,
Alternatively, when a large amount of dust is sucked in more than the capacity, the rotation of the fan may drop due to the muddy viscosity of the water and the resistance of the dust, and a small amount of water may enter the water separator 14. The water separator 14 can be pushed back outside by the action of the long portion 14b inside the blade 14a .

In the above description, the upper part of the intake port 16 is at an oblique angle to the front position and the lower part is the oblique angle to the rear position, and water or liquid containing dust is shaken downward. By shaking off the liquid to the lower part, the fan side fixed cylinder 8 (fan fixed
Water 39 is hardly attracted around the gap 8a between the regular cover 9) and the hood cover 13. The configuration is the same as that described in the seventh embodiment.

In FIG. 35, sixteen intake ports 16 of the water separator are provided, but this number may be increased or decreased according to the size of the water separator 14 to make it an efficient number. There is no intrusion of water and liquid in the water separator 14 described above.

(Embodiment 17) In Embodiment 5, the intake hood 4 is provided at the intake port 6, but a circular guide wall 49 may be provided around the intake hood 4 as shown in FIG. More effective. That is, the intake hood 4 is provided in the fan intake port 6, and a circular guide wall 49 is provided on the outer periphery of the intake hood 4. This increases the gap 8a between the fan side fixed cylinder 8 and the hood cover 13 and the distance to the fan intake port 6 so that air entering from the outside air introduction hole 10 is less likely to flow to the fan intake port 6 side. If the distance is long, the number of outside air introduction holes 10 can be reduced. In this case, the hood cover 13 is
It is desirable to form them like 7, 38 , 39. That is,
As shown in FIG. 38, the hood rib 40 is longer than that of FIG.

(Embodiment 18) The air intake pipe 22a shown in FIG. 1 merely introduces air containing dust into the water 39. On the other hand, those shown in FIGS. 40 and 41 take into account the blowing at the same time as the introduction. This will be described with reference to FIGS. 40a and 40b. FIG. 40a is the side
40b is a perspective view seen from below, and a spatula-like attraction.
The present invention relates to a suction inlet pipe 22a having a plate. this
As shown in FIG. 41, the direction of the blow-out of the air is straight toward the center of the liquid storage case 23, and the air blown into the liquid storage case 23 is moved forward by the air suction inlet pipe 22a having the spatula-like attracting plate . A spatula that restrains water splashing to the top in front of the water separator 14 so that the water 39 pressed by the pressure of the intake air is guided to a position where it hits the bottom of the water separator 14 belongs to. Without the intake inlet pipe 22a, a large amount of water 39 hits the intake port 16 on the side surface of the water separator 14, giving a large resistance to the water separator 14, and causing a drop in rotation, thereby hindering a series of functions. Thus, the intake pipe 22a is important for achieving the above results.

FIG. 41 is an explanatory diagram of the above. Intake air water 39 in the intake momentum discharging in front Te-recoil jump in central, by concentration on the bottom of the per-water separator 14 into water blown up plate 52 with the rotation of the water separator 14 as shown in Figure 41 The water 39 that has hit the water separator 14 mainly scatters radially obliquely upward and acts to absorb or hit the floating dust. A water car in front of the inlet 16 of the water separator 14
The water 39, which has made the ten , is supplied to the lower projection ring 5 provided on the lid 17 of the liquid storage case so as to surround the water separator 14.
Runs down to zero. At this time, it absorbs floating dust,
Or you can hit it to get a double effect. In addition,
The length of the spatula of the intake inlet pipe 22a is the electric fan motor 3
It should be changed according to the horsepower of 4 and the suction power.

During the cleaning operation, the intake pipe 22a does not scatter the water 39 so much that the escape path of the intake is horizontal so that the intake does not jump the water 39 when the main body is turned over. The above is when the water separator 1 is set in the liquid storage case 23 when the main body is turned over.
A part of 4 comes into contact with water 39 at all times. If that is the case, the water separation is performed without any problem. However, when the intake air in the limited liquid storage case 23 scatters the water 39, the jumped water 39 covers the water separator 14 and the water separator is almost submerged. State. Then, the resistance of water increases, and the inflow of air into the impeller 1 decreases, so that the rotation of the fan that rotates by the intake air pressure drops, and the water separator 14 does not perform its original work. Therefore, if the intake air at the time of rollover is the intake air introduction pipe 22a having a structure that does not scatter the water 39, the water 39 does not jump so much. There is no fear of water leakage or intrusion of water into the electric fan motor 34.

(Nineteenth Embodiment) Next, a water blow-up plate 52 shown in FIGS. 41 and 42 will be described. When the power is turned on and the suction force of the electric fan motor 34
a, the air containing the dust that has been dusted is supplied to the intake inlet pipe 22a.
, Ie, near the entrance of the liquid storage case 23. The water 39 is pushed forward by the force that the intake air is discharged in the liquid storage case 23. At this time, the intake pipe 22 is made to prevent the water 39 from jumping before the intake port 16 of the water separator 14.
a jumps near the bottom of the water separator 14, but is mostly pushed to the wall of the liquid storage case 23. The pushed water 39 is blown up to the bottom of the water separator 14 by the water blow-up plate 52. It is scattered by the rotational force of the separator 14. The structure of the water blow-up plate 52 is such that the surface on which the water 39 hits, that is, is concavely curved inward, and
(See FIGS. 41 and 42)

(Embodiment 20) In the present embodiment, when the cleaner is turned over and falls down, if it is tilted to the side, water 39 does not spill out and is also sucked by the electric fan motor 34. Although it does not occur, it is related to a safety device that instantaneously closes the suction port of the electric fan motor 34 when it is tilted to the side or more, stops the suction and prevents the water 39 from entering the electric fan motor 34. It is. ( Refer to the spherical ball 54 shown by the dotted line in FIG. 25 ). If the power is turned off and the vacuum cleaner is turned on, the spherical ball 54 returns to the original position. The spherical ball 54 was provided on a connection pipe F between the water separator and the electric fan motor 34.

The spherical ball 54 is not so light as a table tennis ball used in ball games, but has an appropriate weight. The appropriate weight is a weight that does not float at the time of the intake air passing over the spherical ball 54 during cleaning, and a weight that rolls up so as to cover the suction port when rolled over.

The carrying handle shown in FIGS. 18 and 19 has been described in the eleventh embodiment.
It may be formed as follows. That is, the carrying handle 51 necessary for carrying the main body will be described with reference to FIG. The lower end of the handle 51 is attached to the chassis 25 at an intermediate portion between the liquid storage case 23 and the electric fan motor 34.
It is mounted so that it can move freely by 0 degrees, and is close to the horizontal position when it is stored. The center of gravity of the mounting position is such that the electric fan motor 3
Although it is attached at a position bridging on the 4 side, a stopper is attached to the lower end of the handle 51 so that it does not move more than 90 degrees or 100 degrees, so that water does not spill from the suction inlet 20 of the liquid storage case 23 when carrying. .

(Embodiment 21) A description will be given of FIG. 45, in which a special bag convenient for sucking excrement of a sick person or an infant is provided so that it can be discarded with one touch. The material of the bag may be paper, cloth, synthetic resin fiber, vinyl, etc., and may be manufactured by selecting the material according to the type of garbage to be sucked and the purpose of use. If the upper part, especially the rear part, is made of a material having good air permeability so that the suction air pressure can pass smoothly, it can be removed and discarded with one touch after the suction cleaning. The procedure for setting is the same as that of the currently available paper-pack type vacuum cleaner. After setting the bag, the floating dust presser plate 41 proposed earlier is put on the water separator 1.
After the lid 4 of the liquid storage case 23 is put on the liquid storage case 23 so that the bag 4 and the bag 51 do not come into contact with each other, the water separator 14 is set, and the series of operations described above may be performed.

(Embodiment 22) In the following embodiment,
A fan rotation mark plate 47 is provided above the fan shaft 11 of the water separator so that the rotation of the fan when the power is turned on and off can be easily understood. (See FIG. 26.) The purpose is that when the power is turned off, the electric fan motor 34
Rotate for about a second. During this rotation, air is sucked into the liquid storage case 23, so that the water 39 jumps and scatters to the water separator 14, and adheres to the water separator 14, so that when the brake is applied to the water separator 14, the water is separated. Water remains on vessel 14. In order to shake off the water adhering to the water separator 14, it is desirable that the water separator 14 also rotates by inertia after turning off the power. After confirming that the water separator 14 stops naturally, the water separator is closed by the lid of the liquid storage case 23. 17 is a fan rotation mark plate 47 to be removed from the plate 17. Reference numeral 48 denotes a transparent cover of the rotation mark plate 47. FIG. 44 shows an outer shape for suppressing rollover, and has a wider width. Reference numeral 55 denotes a soundproof cover.

(Embodiment 23) As one of the components of the wet / dry vacuum cleaner of the present invention, it has been shown in Embodiment 8 that the outside air introduction hole 10 is opened in the fan fixing cover 9. The suction efficiency of the vacuum cleaner varies depending on the size (the number of holes) of the outside air introduction holes 10. That is, the size (the number of holes) of the outside air introduction hole 10 is set so that water does not infiltrate in a normal use state, so that there is no significant effect. However, when the amount of air to be sucked in is reduced as in the case of cleaning using a gap nozzle, the ratio of the amount of air flow through the outside air introduction hole 10 is increased and the suction efficiency is significantly reduced.

This embodiment solves the above problem, and an embodiment thereof will be described with reference to FIGS. 46 to 48. First, the lid 17 of the liquid storage case is
By increasing the height of the circular protrusion 17a as shown in FIG. 48, as shown in FIG. 46 and 47, Juan fixing cover 9
So as to cover the outside air introduction hole 10 drilled in, and Juan solid
In order to have a gap that can be ventilated between the regular cover 9 and
Is formed. A plurality of ventilation control recesses 17b are provided at the edge of the circular projection 17a. This ventilation control recess 1
7b is approximately the same size as the size of the outside air introduction hole 10, but is formed to be one half to one third of the total number of the outside air introduction holes 10. The hermetic seal 18 is
For example, it is formed of a material that is easily elastically deformed like a sponge.

The fan fixing cover 9 has the structure shown in FIGS.
As shown by 7, a ventilation control flange 57 is provided on the outer surface.
The ventilation control flange 57 may be formed integrally with the fan fixing cover 9, or may be formed using a relatively soft elastic material and fitted into the fan fixing cover 9. As shown in FIGS. 46 and 47, the ventilation control flange 57 is provided to face the circular projection 17a of the lid 17 of the liquid storage case, and acts as described later.

That is, when cleaning is performed using the gap nozzle or when the mouth of the suction hose is closed, the amount of air to be sucked in decreases, and the air pressure inside the cleaner decreases. Therefore, the fan fixing cover portion D is sucked toward the inside of the cleaner by the external air pressure. By this suction, as shown in FIG. 47, the edge of the circular projection 17a
The ventilation control flange 57 approaches and the circular projection 17a contacts the ventilation control flange 57 as shown in FIG. Since the air flow through the outside air introduction hole 10 is ventilated through the ventilation control concave portion 17b due to the proximity or contact, the air flow is reduced in accordance with the amount of air sucked from the hose.

Therefore, even when a gap nozzle is used, a decrease in suction efficiency can be suppressed. In the above configuration, the same operation and effect can be obtained even if the ventilation control recess 17b is formed on the side of the ventilation control flange 57, or is formed not in a semi-circular hole but in a narrow groove shape.

[0064]

Since the present invention is configured as described above, it has the following effects. The electric fan motor and water separator were separated and installed in parallel, resulting in a low center of gravity, compact size and light weight, and a body weight of approximately 5.0k
g, about 6.5 kg at the time of water injection, with lower center of gravity and better stability than conventional water-separation type vacuum cleaners, and because of its light weight, traveling operation performance and portability are easy, and dust is generally generated by filters such as paper and non-woven fabric. 4. Dry household vacuum cleaner to remove dust
Since it was around 0 kg, the weight was almost unchanged.

Since the electric fan motor does not directly rotate the water separator, the load on the electric fan motor is light and the power consumption is reduced. The electric power of the electric fan motor of the prototype is 650 W, but it is a water filter type. Suction efficiency is good because there is no clogging, and the water separator is 600 g
Since it is light and lightweight, it can be easily set and removed, and work can be performed without any problem as in the above-described embodiment.

By providing the water inlet and the air inlet at the top and bottom, using the water inlet provided above allows water or liquid containing dust to be absorbed without lowering the suction force. Since a large amount of liquid can be sucked and the liquid storage case and the lid of the liquid storage case are transparent, the degree of dust removal can be easily seen from above, and it is easy to determine whether to replace water or discard liquid dirt.

In addition, a separate liquid storage case dedicated to liquid waste is provided so that the waste can be easily and directly transferred to a plastic bag or
It can be placed in bags of paper, cloth, synthetic fiber, etc., making cleaning and disposal easier.
