Abstract

<P>PROBLEM TO BE SOLVED: To improve the environment by inactivating floating bacteria in the ambient air in a place having a large area where a person touches for a long time such as a carpet, bedding, a bed and a floor. <P>SOLUTION: In a bactericidal mode for a mattress 1, a control part 7 in a control box 4 applies an electric current to a high voltage pulse driving circuit 26 of an ion generator 21 and a fan motor 14 of a blowing fan 10, thereby feeding air containing positive and negative ions into a tube 3. The downstream end of the tube 3 is closed to form a dead end, whereby the air filling the tube 3 rises in a plurality of tubes 3A used as branch, and positive and negative ions are gradually discharged to leak out through a release hole in the upper surface of the mattress 1. Thus, an air layer having high concentration of positive and negative ions is formed on the mattress 1 to inactivate mold and bacteria in the air. Accordingly, the mattress 1 is always enveloped in the almost germfree air, so that adhesion of mold and bacteria can be prevented to keep the mattress 1 clean. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a rug such as a carpet, a bedding such as a futon or a blanket, a bed such as a mattress or a treatment bed, or a flooring having a long contact time with a person such as a flooring, and a device for adjusting the surrounding environment of a large area. Things.
[0002]
[Prior art]
Beds such as mattresses and beddings such as futons and blankets absorb a large amount of sweat and tend to cause hygroscopic mold and bacteria to propagate and become unsanitary. Therefore, the bedding is dried and sterilized by drying it in the sun.
[0003]
However, during the rainy season, the humidity is particularly high and the rainy days continue, so you cannot dry your bedding as you wish. Therefore, the futon and the like were dried indoors using a futon dryer. Alternatively, the bedding has been sterilized using ozone gas (for example, see Patent Document 1).
[0004]
However, ozone has a harmful effect on the human body.For example, if high-concentration ozone is inhaled, it may cause inflammation of the respiratory tract, which is dangerous. It was necessary to take care not to leak outside, and to decompose ozone in exhaust gas by providing an ozone decomposition treatment device in the exhaust path.
[0005]
Therefore, it is time-consuming to set up and clean up, and it costs extra power to drive the ozonolysis treatment device, which makes it inconvenient to use. Even if you purchase it, you may stop using it once or twice. Was.
[0006]
Further, for example, Patent Document 2 discloses a method in which an odor confined between futons is passed through an ozone deodorizing device to remove the odor emitted by a bedridden care receiver during incontinence. In this case, an ozone decomposition catalyst filter must be installed on the exhaust side of the apparatus because it is used beside the cared person. In addition, it is necessary to turn on an ultraviolet lamp for generation of ozone and excitation of the ozone decomposition catalyst, which increases running costs.

[Problems to be solved by the invention]
The present invention has been made in view of the above problems, and has a long contact time with a person, such as a rug, a bedding, a bed, and a flooring, and has a large area. It aims to suppress the growth of mold and fungi by activating and improving the environment.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, an environment control apparatus according to the present invention includes an ion generator for generating ions, and a blower for discharging air containing ions, and the air containing ions is supplied from the blower to a surface. It is characterized by flowing along.
[0010]
In addition, a flat device having a large area, which is in contact with a person, an ion generator for generating ions, and a blowing means for discharging air containing ions are provided. It is characterized in that air containing ions is flowed from the blowing means.
[0011]
For example, it emits positive ions and negative ions to a flat surface or a surface that defines a place, such as a rug, bedding, bedding, and flooring, which has a long contact time with a person and has a large area, or around the surface.
[0012]
According to this, it is possible to inactivate molds and bacteria in the surrounding air such as bedding, and to keep the number of suspended bacteria below a certain level. Positive and negative ions have a small effect of inactivating mold and bacteria attached to bedding, etc., but by suppressing the number of floating bacteria in this way, it is possible to suppress the adhesion of mold and bacteria to bedding, etc. Proliferation can also be suppressed.
[0013]
Specifically, the environmental control device of the present invention is a rug such as a carpet, a bedding such as a futon or a blanket, a bed such as a mattress or a treatment bed, or a floor formed on a floor and above and / or below a rug, a bed or a floor. A ventilation path opened at a plurality of locations in the space, an ion generator provided at the upstream end of the ventilation path to generate positive and negative ions, and a blowing means for sending positive and negative ions generated from the ion generator to the ventilation path And characterized by the following.
[0014]
FIG. 9 shows the results of a removal test of Cladosporium (black mold) floating in the air using positive ions and negative ions (hereinafter sometimes collectively referred to as “positive and negative ions”). Cladosporium is a microorganism classified as a fungus such as a mushroom. In the test, a 13.5 m 3 closed container was kept at a temperature of 25 ° C. and a humidity of 42%, and after filling a certain number of live cladosporium spores in the closed container, positive ions and negative ions were supplied. It was done by doing. The graph in FIG. 9 shows the change in the number of Cladosporium traced by an air sampler. The ion delivery conditions in this test were as follows: the air flow was 4 m 3 / min, and the positive and negative ion concentrations were about 40,000 ions / cm 3 at a position 10 cm away from the outlet of the ion blower. When the concentration of positive and negative ions was measured at the center of the target space in the test of FIG. 9, the positive and negative ion concentrations were about 2,000 ions / cm 3 , respectively. As the measurement conditions of the ions, the accelerating voltage of the ion counter is adjusted, and those having a mobility of 1 cm 2 / V · s or more are selectively measured and quantified.
[0015]
As shown in FIG. 9, the number of Cladosporium remaining due to the supply of ions decreases with the passage of time, and the Cladosporium can be almost completely eliminated in about 4 hours after the supply is started. Therefore, positive ions and negative ions inactivate spores of molds (eg, baker's yeast, red bread mold, blue mold, koji mold, water mold, etc.) that live in various environments represented by Cladosporium in the air. Therefore, it is considered that there is an effect of suppressing the reproduction. The appropriate ion generation conditions for obtaining this effect are not limited to the above, and the ion concentration can be freely changed according to the bacterial species and the desired cleanliness conditions.
[0016]
FIG. 10 shows the results of a test of removing Escherichia coli floating in the air by positive ions and negative ions. Escherichia coli is classified as a bacterium to which the most primitive Bacillus belongs among microorganisms. The test was performed by maintaining a closed vessel having a volume of 36 m 3 at a temperature of 25 ° C. and a humidity of 42%, and floating a certain number of living E. coli in this vessel, and then supplying positive ions and negative ions into the vessel. Done. The test results shown in FIG. 10 were obtained by tracking changes in the number of E. coli with an air sampler. In the test of FIG. 10, the ion generation conditions were set to be the same as those of FIG. 9, the air volume was 4 m 3 / min, and the positive and negative ion concentrations were 10 cm away from the outlet of the ion blower. It is set to 40,000 / cm 3 . Since the size of the space is different between FIG. 10 and FIG. 9, by slightly adjusting the direction of the wind and the like, the concentration of positive and negative ions at the center of the target space in the test of FIG. / Cm 3 .
[0017]
As shown in FIG. 10, the number of Escherichia coli remaining due to the supply of ions decreases over time, and Escherichia coli can be almost completely eliminated in about 6 hours after the supply is started. Therefore, it is considered that the positive ion and the negative ion have an effect of inactivating various bacteria represented by Escherichia coli (eg, Salmonella, pathogenic Escherichia coli O157, etc.) in the air, and suppressing their growth.
[0018]
In the tests shown in FIGS. 9 and 10, by applying an AC high voltage between the electrodes, oxygen or water in the air was ionized by receiving energy by ionization, and H + (H 2 O) m ( m is an arbitrary natural number) and O 2 (H 2 O) n (n is an arbitrary natural number) emits ions mainly. These H + (H 2 O) m and O 2 (H 2 O) n adhere to the surface of the floating bacteria and chemically react to generate H 2 O 2 or .OH, which is an active species. Since H 2 O 2 or OH exhibits extremely strong activity, they can surround and inactivate airborne bacteria in the air. Here, .OH is one of the active species, and indicates OH of a radical.
[0019]
Positive and negative ions undergo a chemical reaction on the cell surface of the floating bacteria as shown by the formulas (1) to (3), and generate hydrogen peroxide (H 2 O 2 ) or a hydroxyl radical (.OH) as an active species. I do. Here, in Expressions (1) to (3), m, m ', n, and n' are arbitrary natural numbers. Thereby, the suspended bacteria are destroyed by the decomposing action of the active species. Therefore, airborne bacteria in the air can be inactivated and removed efficiently.
H + (H 2 O) m + O 2 - (H 2 O) n → · OH + 1 / 2O 2 + (m + n) H 2 O ··· (1)
H + (H 2 O) m + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n' → 2 · OH + O 2 + (m + m '+ n + n') H 2 O ... (2)
H + (H 2 O) m + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n' → H 2 O 2 + O 2 + (m + m '+ n + n') H 2 O (3)
[0020]
By the above mechanism, the effect of inactivating floating bacteria and the like can be obtained by releasing the positive and negative ions.
[0021]
In addition, since the above-mentioned formulas (1) to (3) can similarly produce an action on the surface of a harmful substance in the air, hydrogen peroxide (H 2 O 2 ) or a hydroxyl radical (. OH) can substantially detoxify chemical substances such as formaldehyde and ammonia by oxidizing or decomposing them into harmless substances such as carbon dioxide, water and nitrogen.
[0022]
In addition, positive ions and negative ions have the function of inactivating viruses such as the coxsackie virus, and are useful for preventing infection by these viruses.
[0023]
In addition, it has been confirmed that positive ions and negative ions have a function of decomposing molecules that cause odor, and can be used for deodorization of a malodor at the time of incontinence of a cared person.
[0024]
By the way, the above-mentioned ion generator not only generates almost the same number of positive and negative ions, but also changes the characteristics of the pulse voltage applied between the electrodes, thereby biasing the balance of the positive and negative ions to be rich in negative ions and increasing the amount of negative ions. Can also occur. Negative ions have the effect of healing and relaxing human mood.
[0025]
For example, a weight sensor for sensing the weight is provided on the mattress, and when the weight sensor senses the weight of a person, the ion generator generates abundant negative ions and supplies the negative ions to the outside of the bedding by the blowing means. By driving in the relax mode, it is possible to expect an effect that the mood while sleeping is calmed down and that the user can easily sleep well.
[0026]
Then, a heating unit may be provided on the upstream side of the blowing path or the blowing unit.
[0027]
According to this, heating air can be sent to rugs, bedding, bedding, flooring, etc. together with ions or alone, and it can be dried, removing moisture preferred by molds and fungi and suppressing the growth of molds and fungi to some extent it can.
[0028]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described with reference to some specific embodiments.
[0029]
FIG. 1 is a perspective view of a mattress with an air filtering function according to the first embodiment, and FIG. 2 is a top view thereof. Inside the mattress 1 made of cloth, a filler 2 (see FIG. 3) having a cushioning property and formed so as to maintain the external shape of the mattress 1 is accommodated. As a material of the filler 2, for example, foamed urethane is used.
[0030]
One elongated tube 3 having flexibility is embedded in the filler 2 in a meandering manner so as to be folded at the lateral end of the mattress 1, so that an air passage is formed inside the mattress 1. I have. The upstream end 3x of the tube 3 is open and the downstream end 3y is closed. Further, a weight sensor 13 is embedded in the filler 2. The weight sensor 13 detects the presence of a person on the mattress 1, and a plurality of weight sensors 13 may be scattered over the entire area of the mattress 1 in order to increase the detection accuracy.
[0031]
At one corner of the mattress 1, a control box 4 is attached. The control box 4 protrudes outside the periphery of the mattress 1. On the upper surface of the control box 4, knobs and switches, sensors such as a humidity sensor 11 and an odor sensor 12 are provided, and a window (not shown) for visually checking the lighting of the LED display is formed.
[0032]
FIG. 3 is a vertical longitudinal sectional view of FIG. The inside of the control box 4 is vertically partitioned by a partition wall 4A, and below the partition wall 4A is an electrical component storage unit 15 in which electrical components such as the control unit 7 and the high-voltage pulse drive circuit 26 are stored. I have.
[0033]
A large number of tubes 3A, which are tributaries at predetermined intervals, extend upward from the tube 3, which is the main stream. The distal end of the tube 3 </ b> A reaches the upper surface of the mattress 1 and is open to the space above the mattress 1. Therefore, on the upper surface of the mattress 1, as shown in FIG. 2, innumerable air holes 5 are formed along the tubes 3 routed in the filler 2.
[0034]
Above the partition wall 4A inside the control box 4, an ion generating chamber 6 is formed, and an ion generating device 21 is arranged such that a discharge surface faces the ion generating chamber 6. The ion generating chamber 6 communicates with an external space through a suction port 8 provided on the side surface of the control box 4, and is provided upstream of the tube 3 at an air outlet 9 provided on the side surface of the control box 4 in contact with the mattress 1. The end 3x is connected to communicate with the space above the mattress 1 via the tubes 3 and 3A. A blower fan 10 driven by a fan motor 14 is provided near the suction port 8 of the ion generation chamber 6.
[0035]
Next, the configuration of the ion generating element 21 will be described. A plate-like dielectric electrode 24 and a net-like discharge electrode 25 on the surface are arranged inside a dielectric 23 on a flat plate. A high voltage pulse drive circuit 26 is connected to the dielectric electrode 24 and the discharge electrode 25 via a lead wire 27. When the high voltage pulse driving circuit 26 is driven, a high voltage pulse composed of a positive voltage and a negative voltage is applied between the dielectric electrode 24 and the discharge electrode 25, and plasma discharge occurs. As a result, the air around the discharge electrode 25 is ionized, and substantially the same number of positive ions and negative ions are generated.
[0036]
FIG. 4 is a vertical cross-sectional view in the horizontal direction of FIG. 2 and shows another example. A large number of tubes 3A, 3B, which are tributaries at predetermined intervals, extend upward from the tube 3, which is the main flow. The distal ends of the tubes 3A and 3B reach the upper and lower surfaces of the mattress 1, and are open to the upper and lower spaces of the mattress 1. As described above, by forming the tubes 3A and 3B serving as tributaries on the upper and lower sides, ions can be emitted to both surfaces of the mattress 1, and the mattress 1 can be used without distinguishing between the front and the back.
[0037]
Further, as shown in FIG. 5, the tube 3 is vertically divided in a semicircular shape, and two air passages 18 and 19 are formed, and the upper and lower air passages 18 and 19 are formed by a damper device 16 provided in the outlet 9. By switching, positive and negative ions can be selectively emitted to one surface of the mattress 1, and the usability is improved.
[0038]
FIG. 6 is a control block diagram. The humidity sensor 11, the odor sensor 12, and the weight sensor 13 are connected to the control unit 7, and output detection results to the control unit 7.
[0039]
The control unit 7 controls the driving of the high-voltage pulse drive circuit 26 of the ion generator 21 and the drive of the fan motor 14 of the blower fan 10 based on the outputs of the humidity sensor 11, the odor sensor 12, and the weight sensor 13. The timing of such control is determined by the timer 17.
[0040]
FIG. 7 is a flowchart illustrating an example of an operation when the mattress 1 is used. When the mattress 1 is connected to a power source and an operation switch (not shown) on the upper surface of the control box 4 is turned on, various sensors start functioning. First, in step # 10, the humidity around the mattress 1 is detected by the humidity sensor 11 and input to the control unit 7. The control unit 7 compares the humidity around the mattress 1 with a preset humidity value based on this input in step # 11.
[0041]
When the humidity is higher than the predetermined value, an affirmative determination is made in step # 11, the sterilization mode is entered in step # 12, and the high-voltage pulse drive circuit 26 of the ion generator 21 and the fan motor 14 of the blower fan 10 are energized. Air containing positive and negative ions is sent into the tube 3.
[0042]
Since the downstream end 3y of the tube 3 is closed and has a dead end, the air filled in the tube 3 rises up a plurality of tubes 3A serving as tributaries, and is positive and negative so as to leak out from the through hole 5 on the upper surface of the mattress 1. Ions are gradually released. As a result, an air layer having a high concentration of positive and negative ions is formed on the mattress 1, and mold and bacteria in the air are inactivated. Therefore, since the mattress 1 is constantly wrapped in near-sterile air, it is possible to prevent mold and fungus from adhering and keep the mattress 1 clean. Thereafter, the process proceeds to step # 13.
[0043]
Conversely, if the detected humidity is equal to or less than the predetermined value, the determination in step # 11 is negative, and it is determined that mold and bacteria are unlikely to be generated, and the control unit energizes the high-voltage pulse drive circuit 26 and the fan motor 14. Instead, proceed to step # 13.
[0044]
Unless the weight sensor 13 senses the weight, the determination in step # 13 is negative, and it is determined that no person is on the mattress 1, and the above steps # 10 to # 12 starting from the detection of humidity are repeated.
[0045]
When a person gets on the bed on the mattress 1, the weight sensor 13 detects the weight, and the determination in step # 12 is affirmative. The process proceeds to step # 14, where the odor sensor 12 is activated to measure the intensity of the odor around the mattress 1. Detect and output to the control unit 7. The control unit 7 compares the intensity of the odor with a predetermined value in step # 15. If the person is incontinent and smells bad, the intensity of the odor exceeds a predetermined value, and an affirmative determination is made in step # 15, the deodorizing mode is entered in step # 16, and the high-voltage pulse drive circuit 26 and the fan motor 14 are energized. Then, air containing positive and negative ions is sent into the tube 3.
[0046]
The air filled in the tube 3 rises in the plurality of tubes 3A serving as tributaries, and positive and negative ions are gradually released so as to leak out from the through hole 5 on the upper surface of the mattress 1. As a result, an air layer having a high concentration of positive and negative ions is formed on the mattress 1, and molecules of odor (eg, ammonia and methyl mercaptan) in manure are decomposed by the positive and negative ions. As a result, the air around the mattress 1 can be deodorized. Thereafter, the process proceeds to step # 18. Since the positive and negative ions are harmless to humans, they can be safely released even if there is a human on the mattress 1.
[0047]
Conversely, if the odor is weaker than the predetermined value, a negative determination is made in step # 15, and a so-called relaxation mode is entered in step # 17, where the control unit 7 energizes the high-voltage pulse drive circuit 26 and the fan motor 14 to generate a large amount. The negative ions are sent to the tube 3. As a result, negative ions are emitted from the through holes 5 on the upper surface of the mattress 1. As a result, a relaxing effect specific to negative ions can be obtained, and the effect of calming down and sleeping easily can be expected. Then, the process proceeds to step # 18.
[0048]
As long as the weight sensor 13 continues to sense the weight, the determination in step # 18 is affirmative, and it is determined that a person is sleeping on the mattress 1, and the above steps # 14 to # 17 starting from detection of odor are repeated. .
[0049]
When the person who got up soon retires from the mattress 1, the negative determination is made in step # 18, the weight sensor 13 stops sensing the weight, and the process returns to step # 10 to repeat the above operation.
[0050]
Here, it should be emphasized that the above flow is merely an example. In particular, recent research has shown that positive and negative ions have the effect of killing viruses. For example, by supplying positive and negative ions to the surrounding air of the mattress 1 continuously while sleeping, floating influenza viruses and the like can be prevented. Killed and expected to help prevent infection.
By arranging a heating means such as a heater on the upstream side of the tube 3 or the blower fan 10, the heated air can be sent on the mattress 1 together with positive or negative ions or alone to be dried, and mold and bacteria are preferred. By removing moisture, the growth of mold and fungi can be suppressed to some extent.
[0052]
FIG. 8 is a top view of the mattress 1 and shows the second embodiment. In the first embodiment, the positive and negative ions generated from one ion generator 21 are sent to one long tube 3. However, considering that the life of the positive and negative ions is about 3 to 5 seconds. In addition, the number of positive and negative ions reaching the downstream of the tube 3 decreases, and the distribution of the concentration of positive and negative ions discharged onto the mattress 1 becomes uneven.
[0053]
Therefore, in the present embodiment, the mainstream tube 3 is divided at predetermined intervals in the length direction of the mattress 1, and a plurality of tubes 31 to 36 form an air passage similar to the above in the entire range of the mattress 1. . The ion generators 211 to 216 and the blowing fans 101 to 101 are arranged at predetermined intervals along the edge of the mattress 1 such that one ion generator is provided at each of the upstream ends 31x to 36x of the tubes 31 to 36. A plurality of pairs 106 are provided. The control box 4 has a long specification that can cover all the ion generators 211 to 216 in common. The control unit 7 (not shown) provided in the control box 4 uniformly controls all the ion generating elements 211 to 216 and the blowing fans 101 to 106 and operates them all under the same conditions.
[0054]
In this embodiment, since the mainstream tube 3 is shortened, positive and negative ions having a short life can be uniformly discharged onto the mattress 1, and the floating bacteria in the entire space can be uniformly inactivated. Further, the load of the ion generation amount, the blowing speed, and the blowing amount required for each of the ion generators 211 to 216 and the blowing fans 101 to 106 is lighter than a single unit, so that an efficient system can be realized.
[0055]
As described above, the mattress is described as an example.However, the present invention has a long bedtime such as a bed for treatment, a rug such as a carpet, a bedding such as a futon or a blanket, or a flooring or the like which has a long contact time with a person, and has a large area. Applicable to places. In particular, in the case of a flat article such as an electric carpet or an electric blanket in which a heater wire or a heat-sensitive wire is passed through the inside of a woven fabric or a fiber to increase the heat retention, the heating tool itself switches the heating area or the heating area and raises or lowers the sensed temperature. Is provided, the control box can compactly house the ion generator and the blower fan. Since the thickness of electric carpets and electric blankets is not so large, the air containing ions can flow directly along the surface of the carpet or blanket without the need to provide an internal ventilation path like a mattress, so that the surrounding air is suspended. Since bacteria can be inactivated, a simple system can be realized.
[0056]
【The invention's effect】
As described above, according to the environment adjustment device according to the present invention, a rug such as a carpet, a bedding such as a futon or a blanket, a bed such as a mattress or a treatment bed, or a floor having a long contact time with a person such as a flooring has a large area. Positive and negative ions can be released from the surface that defines the flat surface and place to inactivate airborne bacteria, and mold and bacteria can be prevented from adhering to such flat surface and place, and clean Can be kept. Therefore, the frequency of performing sun drying and disinfection can be reduced, and labor can be reduced.
