Abstract

PURPOSE:To easily separate dust by separating the dust by spraying or hitting a jet stream on a material to be cleaned by reusing fan trailing flow energy and utilizing an ultrasonic wave, and furthermore, eliminating static electricity by humidification. CONSTITUTION:Part of a fan trailing flow blows out from a nozzle 22 passing a circulating tube 21 as jet gas, and the dust can be separated from the material to be cleaned by hitting it with the material to be cleaned. The dust separated and entered the air flow is easily sucked from an inlet 17, and is introduced to a filter 18. The energy of the fan trailing flow is converted to mechanical hitting or vibration, etc., with the principles of a wind mill and a blade, then, the dust can be separated by hitting or vibrating the material to be cleaned. When the hitting is used, it is enough to vibrate a hitting piece in the up-and-down direction with a wind force, for example, the rotation of the wind mill of axis flow and axis orthogonal flow, etc., is converted to up-and-down motion with a cam or a crank, etc. Also, a humidification room and the a static electricity elimination agent adding room of an ion generating room 32, etc., are provided on the middle way to a circulating tube 21 which circulates the fan trailing flow, and the static electricity can be eliminated by fitting the humidificated or ionized jet gas on the material to be cleaned in the neighborhood of the inlet 17, which facilitates separation by the air flow of the dust or a brush.

Description

[Detailed Description of the Invention] "Industrial Application Field" This invention is used indoors of buildings such as houses, outdoor structures having a flat area, etc., and is used to drive a fan for sucking air and the fan. This relates to a vacuum cleaner that moves a main body with a built-in motor onto the floor to remove the dirt. "Prior Art" Conventional power vacuum cleaners use an AC commercial power supply indoors and an internal combustion engine outdoors.

Recently, small-capacity, hand-held models powered by secondary batteries have become available on the market, but these have small capacity and low power, and can be used on desks.
It is used on sofas, inside cars, and in limited areas on the floor, but it does not have enough capacity to clean an entire room. For serious cleaning, a floor-mounted type is used. Below, we will explain the conventional technology for the floor-mounted type that is powered by AC commercial power, which is the most frequently used type. As shown in FIG. 15, in the conventional full-scale floor-top type, a main body 11 is movable on the floor with wheels 12, a fan 13 is housed in the main body 11, and the fan 13 is rotated by a motor 14. Air is sucked in from the main body 1l by the rotation of the fan 13, and exhausted from the exhaust port 15 at the other end, and one end of a rigid and/or flexible suction trachea 16 is connected to the suction port. Various replaceable suction ports on the other end of l6
7 is attached, air sucked in through the suction port 17 is passed through a filter 18 in the main body 11, and dust is absorbed by the filter 18. In many cases, the power cord 19 connected to the motor 14 is wound up and stored in the main body 2, and when pulled out, a spring is energized, and when retracted, it is wound up by the relaxing force of the sprig. The suction ports 17 are generally available as elongated ones on the left and right for floor surfaces, circular ones with brushes and long bristles, and spear-shaped ones for slit suction that can be inserted into gaps, and can be used interchangeably. There is. In addition, the suction port 17 for floor surfaces can be manually switched to change the shape of the suction port for smooth surfaces such as floorboards, rubber, vinyl, semi-smooth surfaces such as tatami mats, and surfaces with hairs such as carpets. Comes with levers etc. The suction trachea l6 may be a combination of a rigid one that can be supported by hand and a flexible one that is easily deformed to move the suction port l7 regardless of the position of the main body 1l, or a flexible one that can be easily deformed to move the suction port l7 regardless of the position of the main body 1l. It can be used by directly connecting suction port l7. The filter 1 is used to filter out dust from the sucked airflow and collect the dust, and is also useful for preventing dust from adhering to the rear fan 13 and motor 14. The airflow flowing out from fan l3 is caused by motor l4
It also serves to cool the motor l4, and is finally discharged from the outlet l5. For general residential use and on-floor use, the power is approximately 500W, and this power may adhere to the objects being cleaned.
It is first used to liberate dust that has attracted and adhered to the object to be cleaned due to static electricity using the suction airflow, and then is used to transport the dust into the suction pipe l6 by the airflow. Used to allow airflow to pass through gaps in the dust. A fan 13 and a motor 14 are used to create a negative pressure and a flow rate to give energy to the airflow from the suction port l7 to the filter 18. The airflow passing through the fan l3 is given energy and pressurized to a positive pressure, which further cools the motor 14 and the like, and is discharged from the rear exhaust port l5 as a large amount of high-speed airflow.
This discharged airflow becomes the main source of noise, making it impossible to have a conversation while cleaning. Most of the movement on the floor during cleaning involves moving the main body 11 by manually pulling a flexible tube or support tube by the operator. Also, during this time, the power cord l9 remains stretched and is dragged. There is another type in which the floor suction port 17 and the gripping rod of the main body 11 are directly connected in a straight line obliquely perpendicular to the floor, but it is large and has poor cleaning efficiency.
It is heavy and comes with a cord. As for large cordless vacuum cleaners for floor surfaces, prototypes have been proposed as cleaning robots and some models for commercial use have been announced, but in both cases,
Because it strongly absorbs dust and passes airflow through the dust-filled filter, the efficiency of using the electricity required for cleaning is poor.
The built-in secondary battery is large and heavy, and the overall size is large, making it unsuitable for home or general use. Cleaning robots are designed primarily for unmanned running and cleaning operations. However, the difference between the conventional drive system, which uses push and pull input, and the like is too great, so an intermediate power drive system with manual steering has not been announced. ``Problems to be solved by the invention'' Conventional cleaners require strong suction force to remove dust attached to objects to be cleaned, and require strong airflow to pass through the dust-covered filter. fan,
The motor has become larger. To make it cordless, an internal combustion engine cannot be used indoors because it pollutes the air, so it is necessary to use some type of battery (secondary battery, fuel cell, etc.) and store it inside the main body. However, even for -C residential use, 5
If continuous use is possible for 2R at about 00W, 8 at 12■
OA}I is required. Battery capacity is 100All
This makes the battery too large in both external dimensions and weight, making it impractical. Cordless floor-type models have been announced for commercial use as cleaning robots, etc., but even if the cleaning power is limited to 300W and the usage time is limited to 15 minutes, the battery weight is 2. It weighs approximately 4 kg, making it practical for household use in terms of size, weight, and price, but is limited to commercial use.

In order to reduce the battery capacity, it is necessary to at least double the energy usage efficiency of vacuum cleaners, but there is no vacuum cleaner with such high efficiency in the past, so there is a need to improve efficiency. In addition, if we can improve efficiency, we can make the main components smaller, lighter, and have lower noise.
It can improve mobility and usability. As a method of increasing efficiency, the energy of the airflow frozen from the fan l3 (referred to as fan wake) is used to eject a fan wake near the suction port, and the dust is released by the jet (Jikko Sho 43). -22616 publication, and the one that rotates the brush near the suction port in the wake of the fan (Utility Model Publication No. 39-36
553 Publication) etc. 1! The proposal is publicly known. However, when the latter suction trachea has a suction port extending from the main body, combining the suction trachea with a return trachea for supplying the fan wake to the suction port becomes difficult to handle due to weight and size, and the fan Since the wake is circulated and the fan wake cools the motor, the fan wake becomes high temperature, which reduces safety and gas density, reducing the dust release effect of the fume and the brush rotation effect, so it is still not in practical use. Not yet.

Furthermore, rotating the brushes causes large friction with the floor material and requires a large value of rotational torque, which causes a large pressure loss in the wake of the fan and has the disadvantage of increasing the back pressure of the fan, making it difficult to put it into practical use. was hindering.

A floor vacuum cleaner does not require an extended suction pipe, but it has the disadvantage that it cannot clean non-floor surfaces. It has been reported that vacuum cleaners that are used exclusively for floor surfaces and do not use an extended intake pipe have an operating body that allows a person to move the cleaner while standing. In addition, it has been reported that the clutch is operated by mechanical operation of the operating body and the power is used to move forward or backward, but since it is mechanical, the types of operation are limited, force is required for operation, and it is non-conforming. Since a rigid tow rope or connecting body cannot be used, it is inconvenient to move and store the robot.While some cleaning robots have been announced that can be controlled remotely, there are no vacuum cleaners that are powered by electronic manual control. Neither corded nor cordless versions have been announced. Robots are expensive and have many problems in practical use, such as how to deal with clear conditions and obstacles. Of course, there is no electronic manual control system that can be controlled remotely. Additionally, cleaning robots that can be controlled remotely have the disadvantage that their operation becomes unstable if the communication path between the transmitter and receiver is blocked by a desk, chair, etc. Generally, cleaning work is standardized, and the same areas are cleaned in the same order almost regularly. Housewives are primarily in charge of cleaning at home, and as the standard of living improves and the number of dual-income families increases, there is a demand for labor-saving and automation. It has been extremely difficult to create a lightweight, inexpensive, and practical robot. If we dared to try automation using conventional technology, it would be extremely large and expensive.
It becomes impractical. In addition, robots with a learning function have been announced to facilitate programming during robotization, but all of them calculate the position on the floor from the travel distance sensor and the travel direction sensor, and store the position in chronological order. This method was complicated in calculations, had problems with accuracy, cost, etc., and required a large amount of programs. "Means for Solving the Problem" According to the present invention, any one or a combination of the following means is used to increase the power (or energy) usage efficiency of a vacuum cleaner.

(a) A part of the fan wake is refluxed near the intake hole through the recirculation trachea, and the fan wake is jetted from the nozzle forward near the intake port as a jet, and the jet is made to enter the object to be cleaned.

According to another aspect of the present invention, there is provided a floor cleaner in which a floor inlet, a dust filter, a fan, and a fan driver are housed in a main body, and the main body is provided with a main body weight support that rotates and/or slides on the floor surface. In order to further enable non-floor cleaning, the machine has at least one of the following structures.

The operating body is equipped with a holder for a non-floor suction pipe or a holder for a handy cordless vacuum cleaner. Furthermore, according to another invention, a vacuum cleaner mainly equipped with a drive and steering mechanism for power running on a floor surface has at least one of the following electronic manual control mechanisms. (a) Control self-propelled drive and steering such as forward and backward movement, left and right movement, direction change/rotation, etc. on the grip part (hereinafter referred to as the hand part) of the operating body such as a grip or tow rope provided on the main body.

(c) A mechanism installed at a sufficient height relative to the subject so that the sensor in the receiving section is not obstructed by desks, chairs, etc.

The earlier invention was designed for use on floor surfaces and had a movable main body, which made it easy to absorb dust and was cordless.It was equipped with a track running mechanism and a control circuit for running drive, steering, and vacuum cleaner functions. , furthermore, it has a built-in computer and is manually controlled by a human in advance to clean a specific area, and the control sequence of each control circuit at that time and the position sensor output as necessary are stored as a function of time and/or travel distance. The learning program is executed by a human trigger and is configured to automatically repeat the initial cleaning behavior. If it comes into contact with an obstacle that is not in the learned program during cleaning (from the sensor or motor current), it will stop at that point, interrupt the running and/or homing function, and generate an alarm with sound, light, etc. ．． After removing the obstacle, operate the restart switch to resume automatic driving and cleaning.

A fan 13, a motor 14, and a dust filter 1B are provided within the main body 11, and the earth body 1l is movable on the floor by wheels 12. In this example, it is for the floor, so
A floor air intake port 17 is opened in the front part of the bottom surface of the main body 1l in a semi-cylindrical shape, and the center thereof is an intake pipe l6 and a filter l8.
It is connected to the suction side of the The outer peripheral end of the intake port l7 contacts the floor surface with appropriate pressure. i1N of the fan downstream between the motor l4 and the exhaust port 15 provided at the rear end of the main body 11
! One end of the reflux trachea 21 is connected to R, the reflux trachea 2l is extended forward, and the other end is connected to a nozzle 22 formed at the opening of the intake port 17. A branch adjustment blade 23 is provided at the exhaust port 15, and the branch adjustment blade 23 is adjusted to
The ratio of air volume to reflux is adjusted, and the reflux amount is set to 98% or less. In other words, the amount of suction from the intake port l7 is made larger than the amount of ejection from the nozzle 22.

A part of the fan wake passes through the recirculation trachea 2l and is ejected from the nozzle 22 as a high-speed jet stream. m
Dust is released from the object to be cleaned by applying it to the Ti removal body. Once the dust is released and enters the airflow, it is removed from the intake port l.
7 is more easily sucked in and guided to the filter 18. In conventional vacuum cleaners, power is applied to the fan motor I4, which in turn is applied as energy to the airflow via the fan l3. Airflow energy is expended in moving the dust away from the object to be cleaned at the suction port 17 and then in transporting the dust through the suction trachea 16.
The latter is less common than the former. Furthermore, a large amount of energy is consumed to pass through the pores of the filter 18 and to pass through the dust filtered and accumulated on the filter surface. After that, it passes through the fan 13 and is given energy, cools the motor 14, and is discharged as a large amount of high-speed airflow from the rear exhaust port 15. In other words, most of the electric power is wasted as kinetic energy in the exhaust gas. In the present invention, this waste energy is reused and used to release dust from the object to be cleaned near the intake port l7.

The motor l4 is generally a powerful and small one, and is designed to cool the heat generated by iron loss and w4 loss using the fan flow. Therefore, the temperature of the wake after passing through the motor is high. If this is returned to the nozzle 22 as it is, that is, if the branch regulator 23 sets the discharge amount to
Some devices use this temperature rise to kill mites in dust collection), and the density of circulating airflow decreases, reducing the ability to release dust. However, in this invention, the branch regulator 23 is adjusted so that the amount of ejection from the nozzle 22 is smaller than the amount of suction from the intake port 17.
For example, set it to 98% or less. Therefore, at least 2% or more of cold fresh air is sucked in and the temperature of the ejected air can be lowered. There is an optimal ratio for this. In addition, this intake air of 2% or more has the effect of preventing dust from flying out of the intake port 17 due to the fumes at the intake port 17. In addition, the reflux trachea 21 has a heat exchange function such as a metal tube having cooling fins 24, and the cooling fins 24
By exposing the fan to the outside air, it is possible to cool down the temperature of the refluxed material in the wake of the fan. Alternatively, as shown in FIG. 1, a water-containing film 25 such as fiber or paper having a wide surface wetted with water is placed in the reflux tube 2l parallel to the air flow so that the reflux is cooled by the heat of vaporization. Water-containing film 25
This allows the water in the tank 26 below the reflux trachea 2l to be drawn up into the water-containing film 25 by capillary action. This cooling by the water-containing film 25 imparts humidity to the reflux, which is also useful for removing static electricity from the object to be cleaned, which will be described later.Addition of ice molecules in the fumes increases the gas density and improves the dust transfer M ability.

The energy from the wake of the fan can be converted into mechanical hitting or vibration using the principles of windmills or blades, and the dust can be released by hitting or vibrating the object to be cleaned. When using the beating, the striking piece may be vibrated up and down by wind power, and for example, the rotation of a windmill such as axial flow or cross-axis flow may be converted into vertical motion using a cam, a crank, or the like. It is also possible to oscillate using the principle of fluid elements. Figure 2 is an example of using the Karazawo (rentll) J method.The inlet port l2 and the outlet of the reflux trachea 21 are aligned, and the cylindrical rotating body 28 is rotatably held at the outlet of the reflux trachea 21. As shown in the figure, the circumferential surface of the cylindrical rotating body 28 is formed with notches at five locations, for example, and each of the notches has a valve blade that freely rotates around an axis 29 parallel to the axis of the rotating body 28. 31 is provided.The valve H3l is pulled out of the rotating body 28 by the reflux, and the space formed between the rotating body 2 and the reflux trachea 21 outside the valve H3l is provided with a valve blade 3.
1 becomes blocked, the valve 131 is driven by the reflux, the rotor 2 rotates, and the valve blade 3l collides with the floor, striking the floor. By this beating, the valve blade 31 is accommodated in the notch of the rotating body 28, and enters the airflow in the recirculation trachea 2l again. The number of valve blades 3l provided on the rotating body 28 can be freely designed. In the illustrated example, the valve blade 3l hits the floor five times in one rotation of the rotating body 28. valve! ii The large area of E3L and the valve 5131
This has the advantage that the rise in wake back pressure is small due to the small friction with the floor surface and the small number of mechanical conversion stages. Reflux trachea 2 that circulates the backflow of the fan to remove static electricity when dust is attracted to the object to be cleaned due to static electricity
For example, a static electricity remover addition chamber such as the humidification chamber shown in FIG. 3 or the ion generation chamber 32 shown in FIG. This removes static electricity and makes it easier for dust to be released by air currents or brushes. In the ion generation chamber 32, for example, discharge ': reflux is caused to flow between four electrodes, and the ionization is caused by discharge. The greatest loss of airflow energy occurs when passing through filter 18, especially if filtered dust accumulates on the filter surface. To increase the power usage efficiency of your vacuum cleaner,
It is necessary to remove this accumulated dust as early as possible. For this purpose, as shown in FIG.
has a cylindrical shape and is rotated around its axis, and the airflow from the suction trachea l6 is introduced into the filter l8 from the bottom surface of the cylindrical filter l8, and is discharged to the outer periphery through the filter 18. The part that filters dust and collects dust on the filter is θ with respect to the center of rotation. The remaining angle range θ is the part where the dust accumulated on the filter 18 is scraped off by the scraper 33, for example.
The filter 18 has this θ. , θ, sequentially and alternately. Therefore, the dust accumulated on the filter l8 is quickly removed. A dust storage chamber 34 is provided below the filter 1, and the bottom of the dust storage chamber 34 can be removed if necessary to remove the stored dust. The scraper 33 is arranged inside the filter 18 and has the surface shown in FIG. 4B,
It is fixed to the dust storage chamber 34 at its lower part. The scraper 33 is twisted in a threaded manner so as to generate a force that moves the scraped dust downward in response to the rotation of the cylindrical filter 18. The edge of the scraper 33 is attached so as to be in contact with the filter l8 in the area θ. In the illustrated example, the distances between the edges of the three scrapers 33 and the filter l8 are gradually narrowed in the filter advancing direction. Also, θ. In the area of θ1, the pressure inside the filter 18 is higher than the outside, and the airflow passes through the filter 18 from the inside to the outside. However, in the area of θ1, the pressure outside the filter 18 is higher than the inside, and the airflow passes inward from the outside. Scraper 33
When the dust is scraped off, the scraped dust is prevented from returning to the filter 18, and the dust that remains even after scraping is removed by the airflow directed from the outside to the inside. For this purpose, the member 35 covers the outer surface of the (11) portion of the filter 18, and a part of the fan flow is introduced into the member 35. In the illustrated example, the filter 18 is made of an open material, but metal, synthetic resin, etc. By layering paper filters, etc. on top of the mesh, a flexible endless belt can be realized using the same concept.The belt can bend the path many times while traveling, A filter volume can be formed inside a narrow space. To save power, ultrasonic waves can also be applied to the object to be cleaned near the suction port. If the dust is released with a simple airflow, the airflow becomes steady. For this reason, if the return flow from the fan's wake is used as a jet, the turbulent flow of the fan's wake will have an effect of shaking the dust attached to the object to be cleaned. In addition, shaking the object to be cleaned by hitting or vibrating it, or shaking it with the bristles of a brush can increase the release of dust.However, these methods have a low frequency of shaking, and are still effective in releasing dust. It may be unsatisfactory.It is of course effective to apply air pressure (sound pressure) vibrations using an oscillation source in the human audio frequency range, but it causes discomfort to humans and requires sufficient directivity of sound pressure. This makes it difficult to obtain sound pressure, which causes sound pressure to be radiated in unnecessary directions, reducing efficiency.Using an ultrasonic oscillation source in the audible range or higher (15kHz or higher) can provide sharp directivity, and vibrations that can be focused, etc. Furthermore, if the frequency is too high, the radiation efficiency from the oscillation source to the air will deteriorate and transmission loss will occur.
When used in a vacuum cleaner, the range may be less than 50, making it possible to select the optimum value over a wide frequency range. Figure 5 shows a structural diagram of the vicinity of the suction port 17 where the ultrasonic oscillation source is attached. As the ultrasonic oscillation source, one using electromagnetic force, one using electrostriction, one using magnetostriction, etc. can be used. The illustrated example uses the electrostrictive effect of PVDF (polyvinylidene fluoride). A PVDF membrane 36 is attached to the inner peripheral surface of the semi-cylindrical intake port l7. 5A uses electrostriction in the thickness direction and is pasted on the inner circumferential surface of the intake port 17, while FIG. An air layer 37 is interposed between the outer surface and the surrounding surface.
Both have a semi-cylindrical shape, and the sound pressure is focused on the axial center f of the semi-cylindrical part, strongly vibrating the objects to be cleaned and dust in the vicinity.
Releases dust. Conventional vacuum cleaners have a single suction pipe, and by replacing the air intake port at the tip, they cover all surfaces, including floor surfaces and non-floor surfaces such as walls, shelves, installations, and gaps. For surface use, a suction pipe can be eliminated by directly connecting the suction port to the main body. Judging from the frequency of use in general homes, most of the cleaning is done on floors, and the frequency of use on non-floor surfaces is small. Therefore, in this invention, for convenience of movement and self-propulsion, the floor suction port is integrated with the main body, and the main body is provided with a connection port that allows the suction trachea for non-floor surfaces to be attached and removed separately. Versatility can be provided by means such as having a built-in suction trachea connected to the main body. The suction air passages for floor and non-floor surfaces can be used selectively, but they may also be used simultaneously. In the latter case, for non-floor use, the intake passage must be closed when not in use. Figure 6 shows an example in which a suction trachea for non-floor surfaces is built into the main body, and the holding device for the main body is also used as a gripping tool (operating body) for moving the main body by manual input, which will be described later. It is shown in A rigid non-floor suction trachea 38 is attached to the main body 11 via a connection 39, and the non-floor suction trachea 38 is connected to the main body l1.
It is connected to the suction trachea L6 inside, and a switching valve 4 is installed at the connection part.
1 is provided, and by operating the switching valve 41 by an external operation, either the suction trachea 16 or 38 can be made to communicate with the filter 18 side. The other end of the non-floor suction trachea 38 is connected to a flexible suction trachea 42 .
2 is connected to a convertible intake port 43. The distal end of the flexible suction trachea 42 is housed in a box 44 provided in the non-floor suction trachea 38. The suction trachea 38 for non-floor surfaces is the main body 11
It also serves as an operating body for operating the
5, and the suction trachea 38 is oriented ± from perpendicular to the direction of the arrow.
It is desirable to be able to freely change the angle by about 90' and to be able to stop at that angle with a fleece snap.

A floor vacuum cleaner can be used to clean non-floor surfaces such as shelves, walls, ceilings, etc. by connecting the non-floor suction pipes 38 and 42 to the soil body 1l as described above. However, the suction trachea may be inconvenient in handling as it may be restricted in movement or may hit other objects. For this purpose, as shown in FIG. 6, a general-purpose handy (small) cordless vacuum cleaner 46 with a built-in battery is housed in the box 48 of the operating body 47 (or the main body 11) of the main body l1, or is easily attached and detached. During floor movable cleaning, non-floor surfaces can be cleaned using the cordless vacuum cleaner 46 at any time without being bothered by the suction trachea. A charging plug 49 is provided on the operating body 47, and the small cordless vacuum cleaner 4
If the charging terminal of the vacuum cleaner 46 is connected to the plug 49 when the vacuum cleaner 46 is housed in the Wi4B, it is convenient for use. When the main body 11 operates on an AC power source, the charger 51 can be placed on the main body l1 as shown in FIG. When connected to a charger 52 provided in a storage stand or storage box, the charging voltage can be distributed in parallel to the handy cordless vacuum cleaner 46 as well. Moreover, the storage battery of the handy cordless vacuum cleaner 46 can be charged from the storage battery 53a of the main body 2. These can be used in combination as appropriate by switching. Also, charging period and handy cordless cleaning for main body l1 8
By staggering the charging in time so that the charging period for 46 does not overlap, the maximum current of the charger can be lowered. For charging, the main body II is installed on a storage stand or storage box.
This is done when the battery is stored, and it is desirable that charging is already completed when you want to use it again. When the main body 11 is installed or stored, power is supplied by automatic (or manual) plug connection or electromagnetic coupling, and the charging circuit is automatically disconnected when both the main body 11 and the handy cordless vacuum cleaner 46 are fully charged. This will prevent you from forgetting to charge the battery.

Instead of using commercial power through the power cord 19, a secondary battery is housed in the main body 11 and the fan motor 14 is driven to make the main body 11 cordless, making it convenient for movement and power running. Charging takes place during the idle period. In this case, by using the various dust separation means mentioned above and the dust removal means of the filter, the power usage efficiency is increased, the required electric power is reduced, the secondary battery in the main body is made smaller and lighter, and finally the household A general-purpose cordless vacuum cleaner will be realized. In order to make it easier to move the vacuum cleaner manually, the main body 11
By providing a power travel and steering mechanism to the vehicle, and making it possible to manually and electronically control the power travel function and/or cleaning function, humans can control the control unit (sinch, variable resistor, etc.).
By just doing this, you can save most of the effort for cleaning. Electric power is used as a power source, and automobiles,
This can be easily achieved by applying technology used in transportation vehicles, etc. It does not matter whether there is a code or not. In a simplified case, steering such as running, stopping, moving forward, backward, and turning left and right is sufficient, but if local movement is required, separate drive wheels for left and right movement can be used to move left and right separately from forward and backward movement. There is great convenience in doing so. Simplified cleaning functions include fan activation/stopping, flat dust surface/l. ;It is necessary to switch the intake port on the floor surface and switch between floor surface and non-floor surface.

It is desirable that these electronic controls 1n be performed by a control unit that is located in one place. FIG. 9 is an example in which the electronic control unit is provided in the handle portion 45 of FIG. 6, and the handle portion 45 is
It is slidably fitted into the cylinder at the end of the support rod 53 (38 which doubles as a rigid suction trachea, 47 which does not double as a rigid suction trachea), and can be pushed against the support rod 53 in the direction of the main body l1, pulled in the opposite direction, and moved left and right. The tip of the support rod 53 is held in a neutral position both by pushing and pulling and by twisting from side to side by a spring. For example, Figure 10. As shown in FIG. 11, the support rod 53 is inserted into the handle part 45, and the handle part 45 is held by the support rod 53 so as to be movable and rotatable in the axial direction, and is supported by a coil spring 5556 in the axial and rotational directions. are held at their neutral points. T! ! Hand part 45
Vertical micro switches 5758 are arranged in the axial direction on the support rod 53, and a driving protrusion 59 protrudes from the inner surface of the handle 45 between the operator rollers 57a and 58a of these micro switches 57 and 58. ing. Horizontal microswitch 6 between microswitches 57 and 58
1.62 is attached to the support rod 53 in the opposite direction, and the operator rollers 61a, 62 of these microswitches 61.62
As shown in FIG. 11, a driving protrusion 59 is located between a. As shown in FIG. 12, a microswitch 63 is housed in the grip portion 54, its operator roller 63a protrudes from the grip portion 54, and a rubber cover 64 is provided over the entire grip portion 54.
It is covered. When a person grasps and presses the grip part 5l of the handle part 45, the handle part 45 moves from the neutral position toward the main body, the spring 56 contracts, the spring 55 stretches, and the operator roller 57a of the microswitch 57 moves to the adjustment protrusion. Driven by 59,
These five microswitches operate, and the forward motor operates. Conversely, when the grip 54 is pulled toward the user, the microswitch 5B is actuated by the drive protrusion 59, and the vehicle moves backward. Similarly, when the handle part 45 is rotated to the right using the grip part 54, the microswitch 61 is activated by the drive protrusion 59, and when the handle part 45 is rotated to the left, the microswitch 61 is activated by the drive protrusion 59. 62 is activated and the grip portion 54 moves to the left by its rubber force bar 64.
Microswitch 63 by squeezing it from the outside.
is connected, and fan motor l4 operates. By loosening your grip or releasing your hand, the micro switch 6
3 is disconnected, and fan motor l4 stops. In this way, if you can control the main ml with one hand,
It offers great convenience in use. A control section using a similar group of push button switches, a joystick, etc. may be provided in the grip of the tow rope that appears on the main body l1, or the main body and the operating section may be separately connected by a cord containing a group of signal lines. If you control it with a variable resistor like a joystick, you can control the speed, and you can also change the direction at any angle. Remote control using cordless signal transmission means such as infrared rays, radio waves, and ultrasonic waves has been used for cleaning robots, etc., but it is more useful for non-robot powered vacuum cleaners. The robot's running and cleaning operations are controlled by operating the buttons and joystick on the controller at hand. However, in a room, etc., if a desk, chair, etc. blocks the transmission/reception path, operation becomes unstable. As shown in FIG. 13, the main body 11 has a built-in microcomputer (hereinafter referred to as microcomputer), etc., which can secure a communication path by placing the antenna 6G of the earth body 11 at a high position above the floor, which receives the signal from the remote control unit 65. and at least the control unit (
Position sensor outputs such as reflected waves of ultrasonic waves can be stored as a function of time or travel distance l as needed, allowing humans to manually control specific areas to be cleaned in advance. To clean, first set the location and direction to the subject, then move the subject, perform the control sequence cleaning at that time, and change the direction of the subject at that time (or distance traveled)
The microcomputer learns and memorizes the direction and direction. From the next time onwards, the cleaning action will be repeated according to the sequence 9'n learned the first time, either by setting the main body in the initial posture at the initial starting position and pressing the start button, or each time a pre-programmed time in the microcomputer arrives. Position errors may accumulate over a long period of time (or over long distances) due to differences in initial set postures, differences in running speed, etc., and for this reason, position sensors, contact sensors, proximity sensors, etc. You may also correct the position error. For example, rather than the content of the learning program,
If you hit an obstacle early, the subject's odometer is set and corrected to the distance specified in the learning program to that obstacle. Conventional cleaning robots use a travel distance sensor and a travel direction sensor to calculate the position of the robot and memorize (learn) that position, which requires a complex calculation program and has the disadvantage of poor accuracy. In this invention, each time you open/close each switch for running and cleaning, or operate the angle of a variable resistor, etc., the traveling distance j! I! The program is simple because it is stored as a function of (or time). Accumulating errors can be removed by transmitting ultrasonic pulses at key points, comparing the reflected signals with those during learning, and calculating and correcting position errors. Walls and stationary objects can be identified with proximity or contact sensors and the distance counter can be corrected according to the sequence in the program. In this way, if power efficiency is increased and it becomes practical to use cordless floor vacuum cleaners, floor cleaning can be greatly automated and labor-saving. For non-floor cleaning, only the running on the floor can be automated, non-floor cleaning can be automated manually, and semi-automation can be performed, such as a human accompanying the main subject. After the first run, moving your chair or leaving small items unattended may cause you to collide with obstacles during the first sequence run. In this case, either install a contact sensor in the main body in advance, or detect contact from an interruption in travel, a change in direction, a change in motor current, etc., and immediately stop the control program/sequence and stop the travel drive and cleaning function. Then, it will issue an alarm with sound or light, etc., and request human assistance. Once the person clears the obstruction and straightens the cleaner, the user presses the restart button, and the control program sequence begins continued operation and the drive and cleaning functions are resumed. Furthermore, if the fault cannot be removed without human assistance even after a certain period of time has elapsed, all functions can be stopped to prevent battery consumption.

If a tape player or similar device is installed as the main device and music is played for an appropriate period of time, such as the start, end, and entire period of automatic cleaning, to notify humans, the interface with humans performing other activities will be improved. If the above-mentioned cordless floor vacuum cleaner becomes practical, it will be equipped with an image sensor (for RVs, etc.) and an ultrasonic echo radar, etc., and an advanced system that analyzes the video and echo information will be installed. It is equipped with a built-in computer that has recognition and judgment functions, and is also equipped with a robot hand that is commanded by the computer. Small obstacles on the road are pushed left and right by a barrier placed in front of the vehicle, and large obstacles are removed by the robot hand. This allows for more complete automation, when the floor is a smooth surface (board, vinyl, linoleum, rubber, etc.),
Semi-smooth surface (tatami) or carpet-like flocked surface, m
It can recognize any object, etc., and automatically adjust the distance between the floor surface of the suction port, the brush bristles, the jet port, the ultrasonic focus point, etc., to the floor surface or bristle surface. It is also possible to grasp the inlet port 43 at the end of the non-floor flexible suction trachea with a robot hand and perform automatic cleaning while recognizing and judging the situation on the non-floor surface. Through the above steps, the final goal of an unmanned and automatic vacuum cleaner will be realized. The effects of each item have been explained above, but it is of course possible to combine any items and expect synergistic effects and effects. Recently, attention has been paid to the harmful effects of mites, etc., and methods for killing insects have been announced, such as impact killing using high-speed airflow, and methods that circulate airflow in a closed loop and use heat generated by a motor to increase temperature. However, when cleaning efficiency is increased, the airflow does not need to be high-velocity, and the temperature of the circulating airflow may not increase sufficiently. Especially when going cordless, increased airflow speeds and closed-loop circulating heating can unnecessarily drain the battery. Therefore, in this invention, when the main body is placed on a storage stand or stored in a storage box after cleaning, the power supply connector terminal provided on the storage stand or storage box automatically comes into contact with the power reception connector terminal of the main body. (You can also enter the plug manually (b)
) By detecting weight and contact with a microswitch and energizing an electromagnetic coupling coil, a charger installed externally or in a storage stand/storage box supplies power to the main unit and the handy cordless vacuum cleaner. Charge the storage battery. At that time, as shown in FIG. 18, the heater 67 in the dust storage chamber 34 is energized by the power of the storage battery 53a being charged in the main body to heat the dust, and the insecticidal, fungicidal, and sterilizing agents are evaporated by heating. Energy for killing insects, killing fungi, and sterilizing is obtained from an external AC source by vaporizing and atomizing it and introducing it into the dust storage chamber 34, thereby preventing power consumption of the M battery 53a and generating a large amount of power. Make it usable for insecticide, mold, and fungi. For heating, not only the dedicated electric heater 67 in the dust storage chamber 34 but also closed-loop circulating airflow can be used. For heating, an AC power source may be used directly without going through the charger 52 and the storage battery 53a. In this case, although the number of control circuits increases, the load on the charger 52 and the storage battery 53a can be reduced. By performing charging and insecticidal/moldicidal/sterilization separately and at staggered periods, the current capacity of the charger, storage battery, or AC power source can be reduced. When stored, the insecticidal, fungicidal, and sterilizing processes are automatically performed.
There is an advantage that humans do not have to wait until the process is finished, and there is no need to forget about insecticidal, fungicidal, or sterilizing treatments. The first invention is to increase the cleaning efficiency per unit of electricity used and to reduce the overall electricity consumption of fans and fan motors, etc. This makes cordless systems practical, but even with cords, the cleaning efficiency is reduced. Electrification helps reduce fan noise, and reducing exhaust emissions through the use of fan wakes helps reduce the noise generated raw from the exhaust.
muffler). Therefore, it has the advantage of reducing the noise of the vacuum cleaner. It also helps make the main body lighter and smaller, making it easier to move. The various precepts described above may be used in combination with each other.

By combining any of (a) to (c) of claim 1/claim 6 or any of them, the cleaning efficiency with respect to electric power is increased, the electric power of the fan motor is reduced, the fan motor is made cordless, and the battery capacity is reduced. In addition, the cordless, compact, lightweight, low-noise, floor intake pipe-less input movement J and W vacuum cleaners have a good performance/price ratio, and are easy-to-use, first-level vacuum cleaners with a good absolute price value and widespread use. becomes. The appearance of an example is given in Figure 6. Furthermore, when (a) of claim 8 is combined, a person only needs to operate the control section, and the main body has power running capability, resulting in further labor savings. The handle part in Figure 6 is
As shown in the figure, the control signal line from the handle is connected to the support rod 53.
It integrates with the body and leads it into the subject. It becomes a second level vacuum cleaner. When combined with (b) of claim 8, since it becomes a remote control, rather the non-floor surface is left to a commercially available small handy vacuum cleaner (using a secondary electric ground), and a remote control receiver is added as shown in Fig. 13. provides a 2-A level vacuum cleaner that has a good performance/price ratio and is easy to use. By combining claim 9 with the second level or 2-A level vacuum cleaner, a third level with a learning function,
It becomes a 3rd-A level vacuum cleaner.

While the vacuum cleaner is in the stored position, the internal rechargeable battery is charged in advance using commercial power. The first time a person cleans, starting from the storage position or another specific position (such as a corner of a room), the connection/disconnection status of various (travelling and cleaning) signals at that time is calculated based on the time or the subject's travel. Store (i.e., learn) in the built-in microcontroller as a function of distance or position
. Generally, higher positional accuracy can be obtained by using a function of travel distance rather than time. The distance traveled is obtained from the rotation of the wheels attached to the main body. In the above method, if there is a change in direction angle due to the installation posture of the main body at the starting point (especially the running direction angle) or a change in running resistance during running, the running position is determined by integrating the error angle.
Position accuracy decreases. This error can be anticipated in advance and countermeasures can be taken by, for example, increasing the return width for one scan little by little during learning.

However, if you continuously clean a large room, there is a risk that there will be some residue left behind or that the end of the vacuum cleaner will hit the wall. These are (a) equipped with multiple contact or proximity sensors, run in a straight line until it touches or approaches the front wall, stops, moves sideways to the next scanning line, and detects contact or proximity sensors; This can be corrected by correcting the attitude and further correcting the distance traveled before starting a new scan. Furthermore, (b) ultrasonic echoes are emitted in the front and rear X directions and left and right Y directions, and the arrival time (position information) of the main reflected wave is memorized at the same time as learning, and the echo memory is reproduced from the second time onwards. By controlling the main body's steering in this way, it is possible to drive while almost faithfully reproducing the position at the time of learning. At a higher level, (c) position can be determined using ultrasonic radar, image sensors, etc. The problem in this case is that the placement of items on the floor may be different between learning and actual cleaning. For example, the position of a chair may change each time, and small items may be placed on the floor. Things like leaving something behind on a surface happen every day. This can be prevented by having a person reinstall or inspect the device before cleaning. However, in the unlikely event that due to an oversight, you come across an obstacle while driving that was not present during the learning process, you must either push the small object away with an exclusion barrier attached to the main body, or if the object cannot be pushed away, the driving will stop and an alarm will be set. Considerations such as emitting sounds and requesting human assistance are required. If the cause is not eliminated within a certain time even after an alarm is issued, consideration must be given to disconnecting large power devices such as fan motors or all power from the secondary battery. Improving the interface with humans through music, etc., as mentioned above, is also an important factor. It was explained that the 3rd, 3rd-A level is realized in this way. This method has the advantage of being able to be automated with a relatively small increase in cost. At the third level, only the main movement is automated, and a human accompanies the main movement and performs non-floor cleaning manually. At the 3rd-A level, cleaning of non-floor surfaces, which is difficult to automate and infrequent, is separated and is carried out manually using a hand-held cleaning machine or the like.

At the 3rd or 3rd-A level, altitude sensors such as image sensors (video cameras, ultrasonic radars, etc.) are used to supplement or replace position determination and to recognize obstacles on the road. Decide whether to remove it or add a robot arm to remove it or bypass it. Such recognition and judgment is possible with current technology, but there are problems with increasing costs and increasing the size of the equipment. but,
It is predicted that future prices will fall to a practical level. The floor condition (smooth surface or carpet) can be determined using an image sensor, but it can also be determined based on the reflectance of other light or ultrasonic waves, the degree of scattering of reflected light, etc., and in this case, there is no significant increase in price. ．． This makes it possible to automate the adjustment of the suction port, for example, setting the brush surface up and down. With the above, a 4th level or 4th-A level vacuum cleaner is made, although the price is high. Judging the situation on non-floor surfaces using an image sensor, gripping the non-floor suction port with a robot arm, and automatically cleaning non-floor surfaces is in principle considered a practice in some circles as it recognizes the shape of three-dimensional objects. However, the current technology requires more recognition logic and improvements, and it is necessary to wait for further progress before it can be put into practical use. If this is achieved, a fully automated fifth-level vacuum cleaner will be realized, but practical use will likely take place in the future due to its large size and price.

It is not impossible with current technology.

"Effects of the Invention" According to this invention, the fan wake energy that was previously wasted is reused, and dust is released and humidified by blowing a jet, hitting, or using ultrasonic waves. In addition to making it easier to release dust by removing static electricity, it also moves the filter to scrape off the dust that accumulates on the filter surface, and at the same time allows part of the fan flow to flow backwards to clean the eyes of the filter. By removing the accumulated dust on the filter, which exhibits the highest intake resistance in the system, the cleaning efficiency per unit of power consumption is increased and the power required for cleaning is reduced. This has the effect of making the vacuum cleaner smaller and lighter, making it easier to move and reducing noise. Furthermore, when going cordless, the battery capacity used is reduced, and the battery weight is also reduced, which also reduces the running power when running on power, making it possible to go cordless in terms of size, weight, and price. Suppose that However, based on the above-mentioned effects, mobility has been improved by making it cordless and eliminating the need for an intake pipe when cleaning the floor, which accounts for the majority of cleaning, and by providing a moving grip, it can be used manually or powered. This has the effect of making it easier for people to operate and save labor when moving.

Furthermore, due to the above-mentioned effects, by learning the cleaning control performed by a human for the first time and repeating this learning from the next time, it is possible to simplify measures against obstacles when automating cleaning, and to improve automation by reducing size, weight, and price. This has the effect of freeing people from routine cleaning tasks that are performed almost regularly. Furthermore, the above-mentioned effects make it possible to realize a cleaning robot, and with the advancement of recognition technology, this has the effect of bringing it closer to practical use.
