Description

  The present invention relates to an exhaust circulation cleaner that performs cleaning in a state in which an air suction port floats from a cleaning surface, and an air suction port body used in the exhaust circulation cleaner, and more particularly, exhaust gas ejected from the air suction port body By flowing between the lower surface of the air suction port body and the cleaning surface, the air suction port body can be cleaned in a slightly floating state from the target surface to be cleaned, and from the air suction port body, along with air, The present invention relates to an exhaust circulation type vacuum cleaner that can eject cleaning water, cleaning liquid, hot water, steam, or the like to clean or sterilize a floor surface or the like, and an air suction port used for the same.

  The equipment for cleaning the floor is a washing machine with a work tool such as a mop or rag, a vacuum cleaner, a wet cleaner that can also absorb dirty water, and a brush that rotates by a motor attached to the tip of the handle. There are electric products such as polishers. In order to clean the window glass of a building or the like, a cleaning tool called a squeegee in which a short handle is attached to an elongated rubber flat plate has been used.

  There are two types of vacuum cleaners: a conventional type that discharges exhaust to the outside, and an exhaust circulation type vacuum cleaner. As this exhaust circulation type cleaner, as disclosed in Patent Document 1, by the operation of an electric blower, air is sucked from the suction port of the air suction port body, and the sucked air is passed through a filter to collect dust. The air discharged from the electric blower after passing through the filter is returned to the suction port body through the reflux circuit, and then cleaned while circulating the returned air. ing.

  This type of conventional exhaust circulation type vacuum cleaner does not exhaust exhaust that smells bad like burning dust into the room and exhausts dust and dirt clogged between tatami mats and carpet fibers. It has a high cleaning function that allows it to be sucked and collected after it is lifted, and prevents the air suction port body from adsorbing to the floor etc. due to negative pressure to suck in air and preventing smooth movement. In that respect, it is accepted by many people.

  In addition, in the exhaust circulation type cleaner, such as the outlet cleaner described in Patent Document 2, hot air is blown out from the air outlet, and the surface to be cleaned is sterilized or sterilized and dried. What to do is also disclosed.

Japanese Patent Application No. 2000-376361 JP 2003-299599 A

  The work of cleaning the floor surface using a mop or a rag has a heavy labor burden on the operator, and the work economy is low outside the home. For this reason, an electric vacuum cleaner, a wet cleaner, and a polisher are used. For example, when the floor surface is washed with a polisher, the post-treatment of the detergent and water remaining on the floor surface after washing becomes a problem. For this reason, it is common practice to carefully remove the detergent and oil remaining on the floor with a polisher, or to absorb the detergent and oil remaining on the floor with a wet cleaner. Even if such an operation is performed, the detergent remaining on the floor cannot be sufficiently sucked up, so that a trace of the detergent remains on the floor, and these may float white over time.

  In addition, when a dirty window glass of a building is cleaned using a conventional squeegee, the window is wetted with water and the water is scraped off with a squeegee. If it was not collected well, dirty water would fall and cause inconvenience to passers-by, and its use required considerable skill.

  Among the vacuum cleaners, in the exhaust circulation type vacuum cleaners in the above-described conventional technologies, the air suction port body is moved back and forth while being landed on the floor surface or the like, so that the air suction is performed. The lower periphery of the mouth may rub against the floor or tatami surface and damage the floor or tatami surface. Further, even if the conventional exhaust circulation type vacuum cleaner can circulate the exhaust to clean the floor surface, tatami mats, and carpets, it cannot remove the dirt adhering to the floor surface.

  The problem to be solved by the present invention is that, under such a background, dust and dirt falling on or clogging floors, tatami surfaces, carpets, etc., made of concrete, tiles, etc., as well as dirt, exhaust pressure and exhaust The air suction port body can be removed by sucking and removing the air suction port body.In particular, the air suction port body can be cleaned while being lifted from the cleaning surface by exhaust, and the air suction port body can be moved in the front-rear direction during the cleaning. In the process of moving to clean, water can be rinsed out by spraying clean wash water, etc., and the dirty water after washing and moisture used for rinsing can be sucked up and collected in the vacuum cleaner. To provide an exhaust circulation cleaner that can collect water used for cleaning without dropping it when cleaning glass, and an air suction port used in the cleaner. For the purpose.

  In the exhaust circulation type vacuum cleaner according to the present invention, which is a means for achieving the above-mentioned problems, a vacuum cleaner main body equipped with an electric fan and a filter, an air suction port body having an air suction port and an exhaust jet port, and The pipe connecting the vacuum cleaner body and the air suction port body is assembled, and air is sucked in from the air suction port body due to the negative pressure caused by the rotation of the electric fan. The exhaust after capture is exhausted from the exhaust outlet of the air suction port body, and this exhaust gas is sucked from the air suction port. Exhaust sprayed from the exhaust outlet is circulated between the lower surface of the air suction port body and the cleaning surface, and cleaning is performed in a posture in which the air suction port body is lifted from the cleaning surface. It is characterized by being.

  The exhaust circulation type vacuum cleaner of the present invention (hereinafter abbreviated as the vacuum cleaner of the present invention) includes a dry type that ejects exhaust gas and a wet type that ejects cleaning water together with the exhaust gas.

  The exhaust circulation type vacuum cleaner of any structure is cleaned in a posture in which the air suction port body is lifted from the cleaning surface by the exhaust pressure. This floating is made possible by circulating between the lower surface of the air suction port (nozzle) attached to the tip of the hose of the exhaust circulation cleaner and the cleaning surface (for example, the floor surface). The height (interval) at which the air suction port floats may be small.

  If the air suction port is lifted from the floor or other cleaning surface, for example, when cleaning the carpet, the air suction port will not be sucked by the suction force of the air suction port, so keep the air suction port away from the carpet. Or a troublesome operation of operating a switch for adjusting the strength of suction.

  Also, if the air suction port is lifted from the floor or other cleaning surface, the cleaning surface will not be damaged, and water spilled on the cleaning surface will not be spread on the cleaning surface at the lower surface of the air suction port. , You will be able to inhale efficiently.

  And the biggest reason is that the cleaning efficiency is improved by utilizing the force of ejecting the exhaust gas from the air suction port toward the cleaning surface. For example, if dust or debris adheres between carpet fibers or tatami mats, it may not be possible to remove them efficiently by suction alone. When struck (sprayed), dust and dirt adhering between the fibers and the eyes of the tatami can be lifted, and the dust and dirt floating in this way can be sucked and removed.

  The force for floating the air suction port body is made possible by circulating the exhaust gas between the air suction port and the air suction port of the air suction port body. Further, the pressure (exhaust pressure) at which the exhaust is ejected from the exhaust outlet provided in the air suction port body has a favorable effect on the levitation action.

  This exhaust is caused by the rotation of an electric fan installed in the cleaner body. That is, when the electric fan in the cleaner is rotated, a negative pressure is generated from the air suction port into the cleaner body, and the air sucked by the negative pressure passes through the filter in the cleaner and is then cleaned. In the exhaust circulation type vacuum cleaner according to the present invention, the exhaust gas is ejected (exhausted) from the air suction port body again through the piping path different from the suction from the inside of the cleaner body. It was. In other words, this exhaust is blown out toward the cleaning surface such as the floor, and this exhaust is further circulated between the floor and the lower surface of the air suction port to naturally lift the air suction port. Dust and dust on the floor and the like were put on the flow of the exhaust, and then sucked from the air suction port together with the exhaust and collected in the cleaner body.

  Under the usage condition of the exhaust circulation cleaner of the present invention, for example, when the air suction extension pipe is lifted by hand, the suction force in the direction in which the air suction port is clearly sucked by the cleaning surface due to the influence of atmospheric pressure. Will work.

  In the vacuum cleaner of the present invention, the exhaust pipe may be provided completely separately from the suction pipe, but in order not to lower the handling of the worker who performs cleaning, the suction pipe is provided in the exhaust pipe, Or, conversely, it is preferable to provide a suction pipe inside the exhaust pipe, or to make a pipe with an integral structure in which the side walls of both pipes are integrally connected.

  In order to make the air suction port float, it is necessary to maintain a certain level of exhaust pressure and displacement. However, if the number of rotations of the fan in the main body of the vacuum cleaner is increased, the suction force becomes stronger. The suction port body is easily adsorbed to a cleaning surface such as a floor surface. In the exhaust circulation type vacuum cleaner of the present invention, in order to use the exhaust pressure to lift the air suction port body, the position of the exhaust outlet provided in the air suction port body, the direction of jetting the exhaust, The positional relationship between the jet outlet and the air suction port, the lower shape of the air suction port body, and the like are considered.

  In the vacuum cleaner of the present invention, the exhaust nozzle provided in the air inlet port body is provided in the lower central portion of the air inlet port body, and the exhaust nozzle port is provided in a well-balanced position, so that it is easy to rise. The balance of the flying posture will become stable.

  Then, the air exhaust port is directed perpendicular to the cleaning surface such as the floor surface, or slightly inward from the vertical direction, and air is sucked in a state where the exhaust gas tends to stay below the air suction port body. The air inlet was made to float easily so as to face the mouth.

  Regarding the positional relationship between the exhaust outlet and the air inlet, if the bottom surface of the air inlet is wide, make the gap between the exhaust outlet and the air inlet as wide as possible so that the bottom of the air inlet The configuration is such that as much exhaust gas as possible is likely to stay between the cleaning surface and the air suction port. More preferably, the air suction port is not provided at an offset position so that the air suction port body does not float in an unbalanced posture.

  By the way, about the lower shape of an air suction inlet, it is comprised so that most exhaust may not flow out to the lower part side of an air suction inlet.

  By the way, in the present invention, if the exhaust pressure or the exhaust amount ejected from the exhaust outlet is increased, the air suction port body is likely to rise, and conversely, if the exhaust pressure or the exhaust amount is decreased, the air suction port body is Needless to say, it becomes difficult to ascend, but if the exhaust pressure or the exhaust amount is increased, the exhaust pressure is higher, so that the force sucked into the inside from the lower side of the air suction body is overcome, and dust, dust, etc. The air (exhaust gas) containing air travels straight as it is, and the air (exhaust gas) containing dust or dust may leak to the outside of the air suction port and scatter. On the other hand, if the exhaust pressure or the exhaust amount is lowered, the problem of leakage and scattering as described above does not occur, but the problem arises that the air suction body becomes difficult to float.

  Therefore, in the present invention, the exhaust pressure or the amount of exhaust ejected from the exhaust outlet is adjusted so as not to increase so much that the air (exhaust) containing dust, dust, and dust is brought out of the air suction port body. While preventing leakage and scattering, the end of the flat surface of the air suction port body is formed in an upward curved shape and is directly connected to the inner wall surface of the air suction port. As the exhaust gas rises along the curved surface at the end of the flat surface portion, the air suction port body is more likely to float, and the exhaust gas is prevented from leaking outward, thereby smoothly circulating the exhaust gas. In addition, it is most desirable to configure so that collection of dust, dust and dust can be performed very easily.

  As described above, in the present invention, the exhaust gas flowing between the lower surface of the air suction port body and the cleaning surface forms the end of the flat portion of the air suction port body in a curved shape in the upward direction, and the air suction is performed as it is. By connecting to the inner wall surface of the mouth, the effect of further raising the air suction port body is obtained, and air (exhaust) containing dust, dirt and dust is easily drawn up and circulated. Is most desirable.

  In the vacuum cleaner of the present invention, the exhaust passage or the exhaust passage in the vicinity of the exhaust outlet is narrowed in order to increase the exhaust pressure ejected from the exhaust outlet and to make the air suction port body float easily from the cleaning surface. Is desirable.

  In other words, high exhaust pressure cannot be obtained if exhaust is performed widely, but if the exhaust outlet is throttled in this way, the exhaust is powerfully ejected downward from a part of the lower part of the air intake port body. This is because it helps to lift the mouth.

  Furthermore, in the vacuum cleaner of the present invention, it is possible to cover the exhaust nozzle and the lower surface of the flat portion with a planar body having air permeability. This planar body is intended to clean the cleaning surface by wiping off dust and dirt adhering to the cleaning surface that cannot be lifted by exhaust pressure (air).

  In other words, during normal use, the air suction port floats and removes dust and debris while floating on the cleaning surface, but the cleaning surface does not have stubborn debris that cannot be lifted by exhaust pressure (air). There may be dirt. For this reason, in such a case, the air suction port body is pressed against the cleaning surface against the force that lifts the air suction port body, and the planar body is brought into close contact with the cleaning surface, so that stubborn garbage and By wiping off the dirt, the cleaning surface can be more reliably cleaned. And after wiping off with a planar body, an air suction port body will surface again and will be returned to a normal use state only by canceling the press to an air suction port body. The planar body is preferably detachable so that it can be replaced with a new one.

  By the way, in order to make the air suction port float in a stable posture, if you try to maintain the strong exhaust blowing force, the fan speed in the vacuum cleaner body will increase and a strong suction force will be obtained, If it does in this way, it will become easy to adsorb | suck an air suction inlet on cleaning surfaces, such as a floor surface. For this reason, air suction, exhaust pressure balance, and flow rate balance are required.

  For this reason, in this invention, it is further required for the air suction port body to float on any one of the vacuum cleaner main body, the pipe or the air suction port body, or a connecting pipe connected to any one of them. It is desirable that a pressure adjusting valve for adjusting the exhaust pressure and the exhaust amount is provided.

  The pressure adjustment valve may be adjusted manually, but manual pressure adjustment is cumbersome, and it may be difficult to make adjustments following changes in the rotational speed of the electric fan. .

  For this reason, in the vacuum cleaner of the present invention, the operation of the pressure adjusting valve further stores the data of the exhaust pressure or the exhaust amount and the pressure control program or the flow rate control program necessary for floating the air suction port body in the memory. What is comprised so that it may be performed by the performed microcomputer control is preferable.

  Further, in the present invention, as another configuration, the operation of the pressure adjustment valve is performed by the rotation speed data of the electric fan installed in the cleaner body or the drive current of the motor rotating the electric fan. It is desirable that the control program based on the change data is executed by microcomputer control stored in the memory.

  When the pressure control valve is controlled by a microcomputer, the control is performed in advance by the pressure value, flow rate value, electric fan rotation number, and drive current value flowing through the motor, which are optimally stored in the memory of the microcomputer. Any one or more of these are performed in accordance with a simulated control program, and the microcomputer control is a detection signal by at least one of a sensor for detecting the pressure of suction and / or exhaust, or a sensor for detecting the rotation speed of the electric fan. It is desirable to be configured so as to be detected and controlled. If comprised in this way, even if it changes the rotation speed of an electric fan within a fixed range, an air suction inlet can be levitated.

  Further, in the present invention, not only the dust and dirt on the floor surface are sucked from the air suction port body and collected, but also water and moisture adhering to the cleaning surface such as the floor surface, the wall surface or the glass surface together with the air. Therefore, it is desirable that the cleaner main body is provided with a recovered water storage container that collects water and moisture ejected from the exhaust outlet of the air suction port.

  By the way, in the cleaner of the present invention described above, the exhaust is a dry type exhausting only air. However, in the present invention, the cleaning water is further provided in the cleaner body or in a location adjacent to the cleaner body. A storage container is provided, and the cleaning water in the cleaning water storage container is driven by the pressurization and / or negative pressure of air generated by the rotation of the blower fan, or the pump provided in the cleaner body The cleaning surface is washed with air from the exhaust outlet of the air suction port body, and the cleaned water flows from the air suction port of the air suction port body into the collected water storage container in the cleaner body. What is configured to be recovered is desirable.

  In this wet type exhaust circulation cleaner, the dry structure described above is also provided, and cleaning water is mixed into the exhaust, and the exhaust is ejected from the exhaust outlet of the air suction port toward the floor surface together with the exhaust. The cleaning surface such as the floor surface is washed with cleaning water, stains and dirt on the floor surface are removed, and the cleaned sewage is sucked from the air suction port and sent to the vacuum cleaner body for recovery. is there.

  In this way, when the mist-like or water-drop-like washing water is ejected from the exhaust outlet of the air suction port body together with the air, stains and dirt adhering to the floor surface with this moisture can also be removed. . In addition, in the process of moving the air suction port back and forth, it becomes possible to rinse with clean cleaning water that has been blown out. Then, the dirty water after cleaning and the water used for cleaning are sucked from the air suction port of the air suction port body and sent into the cleaner body to be collected.

  In addition, in the case of this wet type exhaust circulation cleaner, the planar body covered on the exhaust outlet and the lower surface of the flat portion is one having air permeability and water permeability.

  In the present invention, in the vacuum cleaner, a heater for warming the cleaning water is provided in the cleaning water storage container or in a pipe portion through which the cleaning water flows, and the warm water heated by the heater is It is more desirable that it is constructed so that it is ejected from the exhaust outlet of the air suction port together with air, and stains and dirt attached to the floor surface are better removed with hot water, or after washing The floor surface can be effectively dried.

  Furthermore, in the vacuum cleaner of the present invention, a steam generator for evaporating the cleaning water is provided at an intermediate position of the cleaning water storage container or the piping through which the cleaning water circulates, and the steam is in the air suction port body together with the air. What is configured to be discharged from the exhaust outlet is preferable, and with this configuration, the steam is injected from the exhaust outlet to further clean dirt and oily dirt adhering to the floor surface. It can be removed.

  In the vacuum cleaner of the present invention, the washing water storage container is preferably composed of a disinfecting liquid, a sterilizing liquid, or a sterilizing liquid container. When configured in this way, for example, on the floor of a hospital It is possible to prevent nosocomial infections by spraying a disinfectant solution that sterilizes adhering germs, pathogens, and the like together with air from the air suction port to a cleaning surface such as a hospital floor.

  The vacuum cleaner of the present invention described above includes those for floor cleaning and / or floor cleaning, and the suction port floating type exhaust circulation cleaner is for window glass cleaning and / or The thing for wall surface washing | cleaning is mentioned.

  In the vacuum cleaner of the present invention, cleaning and rinsing can be performed in the process of moving the air suction port back and forth in a structure in which cleaning water, cleaning liquid, warm water, water vapor or disinfecting liquid is ejected together with exhaust gas. It is. That is, the floor or the like is washed or sterilized with water or water vapor ejected together with air from the exhaust outlet, and not only the dirty sewage after the washing or sterilization is sucked from the air inlet, By moving, clean water is again sprayed and circulated, so that the water is rinsed, and the water after the rinse is sucked from the air suction port and can be collected.

  Further, in the present invention, it has been determined that it is preferable that the air suction port body that constitutes a part of the exhaust-circulation type vacuum cleaner is also authorized, and in the air suction port body according to the present invention, An air suction port body that constitutes a part of the exhaust circulation cleaner according to any one of the preceding claims, wherein an exhaust nozzle is provided at a lower central portion of the air suction port body. A flat portion for allowing the exhaust air to flow through the cleaning surface and causing the air suction port body to float from the cleaning surface is formed around the outlet of the jet port, and further, an air suction port is formed around the flat portion. It is characterized by this.

  In this way, if the exhaust outlet is provided at the lower central portion of the air inlet port, the exhaust flow path from the exhaust outlet to the air inlet port spreads evenly in the left and right and front and rear directions in the plane direction. Mouth body is stable and easy to float in posture. In addition, if the air suction port is provided around the exhaust nozzle, cleaning can be performed on a wide area below the air suction port body.

  Further, in the present invention, the air outlet is preferably formed in a slit shape in which the length in the lateral direction is long and the width in the front-rear direction is narrow, and when configured in this way, This is desirable because the floor surface and the like can be widely cleaned when the air suction port body is moved back and forth by the exhaust nozzle formed widely in the lateral direction.

  Thus, when the exhaust outlet is formed in a slit shape that is long in the lateral direction and narrow in the front-rear direction, it is ejected from the exhaust outlet and the lower surface of the air inlet port Exhaust gas flowing between the cleaning surface and the air suction port body spreads widely under the air suction port body, and the air suction port body can be lifted with a good left-right balance.

  In the present invention, it is also preferable that the air suction port is formed in any one of a rectangular shape, a circular shape, and an elliptical shape along the lower periphery of the air suction port body. With the air suction port formed along the line, a highly efficient cleaning efficiency can be obtained in a wide area under the air suction port body.

  By the way, in the present invention, the slit shape means a long slot having a relatively narrow width and a long shape.

  Moreover, in this invention, what is formed so that adjustment of the space | interval with a cleaning surface is desirable by comprising the flat part of an air suction inlet so that attachment or detachment is possible.

  In this way, if the gap between the cleaning surface and the cleaning surface is formed to be adjustable, the exhaust gas flowing between the lower surface of the air suction port body and the cleaning surface can be easily retained below the air suction port body, It is possible to further increase the floating of the air suction port.

  Further, in the air suction port body according to the present invention, air (exhaust) containing dust, dust, and dust is adjusted by adjusting the exhaust pressure or the exhaust amount ejected from the exhaust outlet so as not to be so high. While preventing leakage and scattering to the outside of the suction port body, the end of the flat portion of the air suction port body is formed in an upward curved shape and is directly connected to the inner wall surface of the air suction port. The exhaust gas ejected from the exhaust gas outlet rises along the curved surface at the end of the flat surface portion, so that the air suction port body is more likely to float and the leakage of the exhaust gas to the outside is prevented. It is most desirable that the exhaust gas not only be smoothly circulated, but also be configured so that dust, dust, and dust can be collected very easily.

  As described above, in the present invention, the exhaust gas flowing between the lower surface of the air suction port and the cleaning surface forms the end of the flat surface portion of the air suction port body in an upward curved shape, and the air suction port as it is. By connecting to the inner wall of the air intake, the effect of further raising the air intake port body can be obtained, and air suction that makes it easy for air (exhaust) containing dust, dirt and dust to be sucked up and circulated upwards The mouth is also preferred.

  When the air suction port body according to the present invention is configured as described above, the air ejected from the exhaust air outlet in the air suction port body is not immediately sucked from the air suction port, so that the air suction port body has an action of rising. In addition, since cleaning water, cleaning liquid, warm water, water vapor, disinfecting liquid, etc., which are ejected together with air from the exhaust outlet, come into contact with the cleaning surface, cleaning, disinfection or sterilization can be performed effectively. is there. The air flow passage here may be used to increase the time it takes for exhaust after being blown into the air suction port, or to make it difficult for the exhaust to escape immediately around the air suction port. included.

  Moreover, in this invention, it is also possible to coat | cover the planar body which has air permeability or air permeability and water permeability on the lower surface of an exhaust nozzle and a plane part.

  This planar body is formed of a porous material such as sponge, cloth, chemical fiber, etc., has good durability, can obtain a stable air permeability, and resists the force that floats the air suction port body The cleaning surface can be more reliably cleaned by pressing the air suction port against the cleaning surface, bringing the planar body into close contact with the cleaning surface, and wiping stubborn dust, dirt, and dust. The planar body is preferably detachable so that it can be replaced with a new one.

  Further, in the air suction port body according to the present invention, the air suction port body is attached to the exhaust circulation cleaner and is used for cleaning a window glass or a wall surface, and the air suction port body has a cylindrical shape. And an outer case part connected to the outer cylinder and extending in a fan shape in the lateral direction, and connected to the inner cylinder. And an inner case portion having a smaller shape than the outer case portion so as to extend along the outer case portion and spreading in a fan shape in the lateral direction, between the front and rear outer case portions and the inner case portion. The exhaust path is formed with a predetermined interval, and the air suction path is formed in the inner case part communicating with the inner cylinder, and the inner case part which is the front end of the air suction path is formed. Long slit in the horizontal direction at the front end In addition, a slit-shaped exhaust nozzle that is long in the lateral direction is formed at the front end between the front and rear outer case portions and the inner case portion, which are the front end of the exhaust passage. It is characterized by being.

  In this air suction port body, any one of cleaning water, cleaning liquid, warm water, disinfecting liquid, and the like is mixed and jetted from the exhaust outlet together with air. And if an exhaust nozzle and an air inlet are formed long in the horizontal direction in this way, the window glass can be cleaned widely by one operation. Moreover, since the air suction ports are provided on both sides along the vicinity of the exhaust jet outlet, the window glass can be cleaned cleanly by the water jetted from the exhaust jet outlet. All the air can be sucked in from the air suction port without dropping downward, which is desirable because it does not sew the passerby or contaminate the falling surface. By the way, in the air suction port body for cleaning the window glass or the wall surface, the air suction port body is lighter than the air suction port body for floor surface cleaning. There is no need to lift from the wall.

  According to the exhaust circulation cleaner of the present invention having the above-described configuration, the following effects can be obtained.

  First, in the exhaust circulation type cleaner of the present invention, the air suction port body can be slightly lifted from the cleaning surface by the exhaust gas ejected from the air suction port body in the cleaner. The dust, dust, water, etc. on the cleaning surface can be sucked and collected while moving back and forth on the cleaning surface with the air suction port floating. As a result, when cleaning the carpet, it is possible to eliminate the trouble that the carpet is sucked by the suction force of the air suction port body, and the air suction port body can be smoothly moved in the front-rear direction. Is played.

  In addition, when cleaning is performed by moving the air suction port body back and forth, there is an effect that the tatami mat or the carpet is rubbed with the air suction port body and the harmful effect such as damage is not generated.

  Secondly, in the exhaust circulation type cleaner of the present invention, exhaust gas is ejected from the air suction port toward the cleaning surface. After the dust and fine dust adhering between the eyes are raised, the high suction effect is obtained by sucking the dust.

  Thirdly, in the exhaust circulation type cleaner of the present invention, the end of the flat surface portion of the air suction port body is curved upward and is continuously connected to the inner wall surface of the air suction port. The ejected exhaust gas is guided to the inner wall surface at the end of the flat part in the previous period and is formed in a structure that is easily circulated upward.

  For this reason, in the exhaust circulation cleaner of the present invention, air (exhaust) containing dust, dust, and dust is adjusted by adjusting the exhaust pressure or the amount of exhaust ejected from the exhaust outlet so as not to increase so much. While preventing leakage and scattering to the outside of the mouth body, by forming the end of the flat portion of the air suction mouth body in an upward curved shape, as it is connected to the inner wall surface of the air suction mouth, Exhaust gas ejected from the exhaust air outlet flows between the lower surface of the air suction port and the cleaning surface, and rises along the curved surface at the end of the flat portion, so that the air suction port body is more likely to float. In addition, the exhaust gas is prevented from leaking to the outside and the exhaust gas is smoothly circulated, and there is an effect that dust, dust, and dust can be collected very easily.

  Fourthly, in the exhaust circulation cleaner of the present invention, the exhaust outlet and the lower surface of the flat portion are covered with a breathable or planar material having breathability and water permeability. Even the dust and dirt adhering to the cleaning surface that cannot be floated by the exhaust pressure (air) in the state of the object can be floated or wiped off, so that the cleaning surface can be reliably cleaned.

  Fifth, in the exhaust circulation cleaner of the present invention, if the pressure of the exhaust gas ejected from the air suction port body can be adjusted by the pressure adjustment valve, the air suction port body can be further balanced. If the pressure adjustment valve can be controlled by microcomputer control, it is not necessary to adjust the pressure adjustment valve manually. Even when the number changes, the air suction port can be lifted in a balanced manner.

  Sixth, in the exhaust circulation type cleaner according to the present invention, when a collected water storage container for storing the sucked sewage and moisture is provided in the cleaner body, the spilled spilled water on the floor surface can be sucked and recovered. As a result, the workability is further improved.

  Seventh, in the exhaust circulation type cleaner of the present invention, if any one of cleaning water, cleaning liquid, hot water, water vapor, etc. is jetted together with air from the air suction port body, As a result of not only sucking dust and debris, but also cleaning the floor surface cleanly as if it was wiped with water, especially stubborn dirt and oily dirt on the floor etc. Can also be washed, and then the sewage after washing can also be sucked in. In particular, in the process of cleaning by moving the air suction port body back and forth, it is possible to rinse the floor surface or the like by spraying clean washing water or the like. In addition, a series of processes, including washing, rinsing, collecting dust and dirt, and collecting water (sewage) used for rinsing, can be performed simply by moving the air suction port back and forth. There is an effect that shortening can be realized.

  Eighth, in the air suction port body that constitutes a part of the exhaust circulation cleaner according to the present invention, an exhaust nozzle is provided at a lower central portion of the air suction port body. A flat portion is formed around the outlet to allow the exhaust air to flow through the cleaning surface and the air suction port body to float from the cleaning surface. Further, when an air suction port is formed around the flat portion, The suction port body can be lifted in a well-balanced manner, and the air suction port is provided around the exhaust jet port, so that cleaning can be performed on a wide area below the air suction port body. There is an effect such as remarkable improvement.

An air suction port 18 is formed between the peripheral edge portion.

  As shown in each drawing of FIG. 5, in the use of the first shape air suction port body 14, the exhaust gas sent from the cleaner body 2 into the exhaust passage A by the rotation of the electric fan 4 is exhausted. Air is ejected in the vertical direction from the ejection port 19 toward the cleaning surface F, and is exhausted by the exhaust gas flowing between the lower surface of the air suction port body 14 and the cleaning surface F after being ejected by the ejected exhaust pressure. The suction port body 14 is configured to float from the cleaning surface F, and in this state, the air suction port body 14 can be used by smoothly moving back and forth.

  That is, as shown in FIG. 5B, the air suction port body 14 is pressed against the cleaning surface F by its own weight, the atmospheric pressure, and the suction force that sucks air from the air suction port 18. Force acts in the direction (arrow P direction), but the exhaust gas ejected from the exhaust air outlet 19 of the air inlet port 14 acts and circulates between the lower surface of the air inlet port 14 and the cleaning surface F. The air suction port body 14 always has a floating direction (arrow U direction), and the air suction port body 14 always floats from the floor surface F with a constant interval.

  When cleaning is performed in a state where the air suction port body 14 is lifted in this way, the air suction port body 14 can smoothly move on the cleaning surface F. It is not adsorbed on the surface. In addition, dust and dirt on the cleaning surface F rise due to the exhaust, and together with the exhaust, the dust and dirt are sucked into the air suction path B and collected, and the dust and dirt are collected and captured by the electric filter 5. Exhaust gas circulation is performed in which the exhaust gas after being sent is sent again into the exhaust passage A.

The curved surface R connected to the inner wall surface 18 is formed, and the exhaust gas ejected from the exhaust nozzle 19 is guided to the curved surface R at the end of the flat portion 20 and is easily sucked and circulated upward. It is configured.

  Therefore, the exhaust gas ejected from the exhaust nozzle 19 circulates between the flat surface portion 20 and the cleaning surface F, but eventually the exhaust gas is indicated by an arrow along the curved surface R at the end of the flat surface portion 20. In addition, since the air suction port body 14 is more easily floated and is guided and circulated in the upward direction, it is possible to reliably prevent the exhaust from leaking and scattering to the outside of the air suction port body 14. Further, since the end of the flat surface portion 20 is curved upward and is directly connected to the inner wall surface of the air suction port, exhaust air can be sucked and circulated smoothly, and dust, dust, dust, etc. This can be very easily performed.

  Thus, in this embodiment, the exhaust gas flowing between the flat surface portion 20 and the cleaning surface F is directed upward along the curved surface R at the end of the flat surface portion 20 in the air suction port body 14, so that the air suction port The effect of further raising the body 14 is obtained, and dust, dust, and dust are also raised upward, and are smoothly sucked from the air suction path B into the air suction pipe 16 to facilitate exhaust circulation.

An air suction pipe 16 for connecting to the air suction pipe 9 is projected, and an exhaust pipe 17 having a smaller diameter than the air suction pipe 16 is located in the air suction pipe 16. Is communicated with a space formed by a case portion 15 in the air suction port body 14 and an inner wall portion 22 formed with a space from the case portion 15, and this space is an air suction path. B, and the lower end portion of the air suction path B is formed in the air suction port 18.

  A small-diameter exhaust pipe 17 is positioned inside the air suction pipe 16, and the lower end portion of the exhaust pipe 17 is formed wider toward the lower side, and is flat with an inner wall 29 having a narrow front and rear width. A slit-like exhaust outlet 19 that is long in the left-right direction is formed at the center of the flat portion 20.

  As shown in FIG. 9B, the exhaust gas ejected from the exhaust nozzle 19 ventilates the planar body S and collides with the cleaning surface F. Further, this exhaust gas passes through the exhaust nozzle 19 and the air suction port 18. By flowing in the direction, dust and dust are removed while the air suction port body 14 is lifted upward.

  However, stubborn dust or dirt that cannot be lifted by the exhaust pressure (air) may adhere to the cleaning surface F.

  In such a case, the air suction port body 14 is pressed against the cleaning surface F while resisting the force that causes the air suction port body 14 to float, and the planar body S is moved in close contact with the cleaning surface. Thus, stubborn dust and dirt adhering to the cleaning surface F can be wiped off, and the cleaning surface F can be more reliably cleaned.

And after wiping off with the planar body S, the air suction port body 14 floats up again and is returned to a normal use state only by canceling the pressure to the air suction port body 14.
The planar body S is preferably detachable so that it can be replaced with a new one.

  In the cleaner main body 2 shown in FIG. 18, a water storage container 45 for storing cleaning water is accommodated, and a filter 5 for filtering dirty water is provided above the water storage container 45. The suction and exhaust of the vacuum cleaner main body 2 is performed by the rotation of the electric fan 4 as in the vacuum cleaner main bodies of the above-described embodiments. However, air is exhausted from the exhaust outlet 7a to the exhaust hose 11a. The air containing the water in the water storage container 25 is ejected to the exhaust hose 11b.

  For this reason, air blows forward from the front end portion of the exhaust passages A and A closest to the inner wall of the outer case 38 of the air suction port body 14 and forwards from the front end portions of the exhaust passages 55 and 55 inside thereof. Moist air is blown out.

  Referring to FIG. 18, the method of using the air suction port body 14 for wiping a window according to the fifth embodiment and its function will be described. The air suction port 14 is turned on with the power of the cleaner body 2 turned on and the electric fan 4 rotated. The entire distal end portion of the body 14 is set along the window glass surface G. If it does in this way, the air spouted from the front-end | tip part of exhaust path A, A by the negative pressure by rotation of the electric fan 4 will hit the glass surface G, will flow in the direction which spreads along the glass surface G, and exhaust path A, In addition to the relatively small diameter of the exhaust passages 55, 55, the tip of the water containing water droplets or mist-like water ejected from the distal ends of the exhaust passages 55, 55 located inside the A Since the portion has a narrowed shape, it is strongly ejected toward the front glass surface G.

  For this reason, in this embodiment, a flow layer of air spouted from the front end portion of the air suction port body 14 is generated between the glass surface G and the front end portion of the air suction port body 14, and the air suction port body 14. The tip of the air suction port is slightly lifted from the glass surface G, but since the suction action that much of the jetted air is sucked from the air suction port 14 is also working, the tip of the air suction port 14 is made of glass. Even if the operation is performed in the direction of pressing against the surface G, the tip of the air inlet port 14 does not come into contact with the glass surface G, and an appropriate interval is maintained.

  For this reason, the air ejected from the front ends of the exhaust passages A and A provided along the inner wall surface of the outer case 38 of the air suction port body 14 and the air jetted from the front ends of the exhaust passages 55 and 55. Dust and dirt adhering to the glass surface G are removed by water droplets or mist-containing air, and in particular, water droplets ejected from the front ends of the exhaust passages 55 and 55 or Since the mist-like water containing water is strongly ejected, the glass surface G can be cleaned cleanly in the same manner as when cleaning with a brush and water.

  Then, the sewage adhering to the window glass surface G is sucked into the cleaner body 2 through the air suction port 14, and the sewage sucked into the cleaner body 2 has large dirt particles in the filter 5. It is removed and stored in the lower water storage container 45.

  In addition, in the cleaner main body 2 shown in FIG. 18, the filter 5 is provided above the water storage container 45, and it is comprised so that the sewage inhaled in the cleaner main body 2 from the air suction inlet 6 may be filtered. However, for example, a partition formed by a vertical filter is provided in the center of the water storage container 45, and the sewage sucked into one side partitioned by this partition is put, so that the water filtered by the partition is stored on the other side. Thus, the purified water may be sucked again.

  Further, instead of the above embodiment, for example, as shown in FIG. 19, a recovered water storage container 45 for storing dirty water is provided inside the cleaner body case, and water for storing the washing water W outside the cleaner body case. A storage container 25 is attached, and one end portion of the exhaust hose 11b on the base side is connected to the distal end portion 27a of the discharge pipe 27 attached toward the water storage container 25, and the cleaner body 2 One end of the exhaust hose 11a is connected to the base side of the exhaust hose 11a, and one end of the air suction hose 8 is connected to the air suction port 6 of the cleaner body 2, Clean water in the water storage container 25 is ejected from the air suction port 6 using negative pressure, and the sewage collected from the air suction body 14 is stored in the recovered water storage container 45 in the cleaner body 2. You can do it

  Further, as in the cleaner body 2 shown in FIG. 20, the recovered water storage container 45 and the water storage container 25 are provided side by side, and these are partitioned by the filter 5 to collect the sewage collected in the recovered water storage container 45. The filter 5 may be filtered and moved into the water storage container 25.

  In this case, the movement of the water from the recovered water storage container 45 into the water storage container 25 naturally occurs to compensate for the decrease caused by the wash water W in the water storage container 25 being sucked from the discharge pipe 27. Although it is performed, the negative pressure due to the rotation of the electric fan 4 provided in the cleaner body 2 is used, or the sewage in the recovered water storage container 45 is sucked with a pump and transferred into the water storage container 25. Suction filtration may be performed.

  In addition, as the exhaust circulation type cleaner body 2 to which the air suction port body 14 is connected, those of the above-described embodiments are preferably used. Therefore, the description is omitted here to avoid duplication.

  FIG. 21 is a side cross-sectional schematic diagram showing another embodiment of the air suction port body 14 for wiping windows shown in FIGS. 18 to 20. The air suction port body 14 for wiping the window is provided with a small-diameter pipe 39 formed at a constant interval in the outer case 38, and an exhaust jet at the narrowed tip portion of the pipe 39. Moist air from the outlet 19 is strongly blown toward the front glass surface G to float dirt on the glass surface G. As a result, the glass surface G is cleaned cleanly as when washed with a brush and water. It can be washed.

  Then, the sewage adhering to the window glass surface G is sucked into the air suction port 18 provided adjacent to the periphery of the exhaust jet port 19, and passes through the exhaust path A provided between the outer case 38 and the pipe 39. Even if it is sucked into the cleaner body 2, the same effect as described above can be obtained.
