Description

  The present invention relates to an air conditioner, a fan heater, and a method for deactivating antigenic substances. In particular, the present invention relates to an air conditioner and a fan heater that can generate positive ions and negative ions.

  In recent years, along with changes in the living environment, living in a comfortable environment in which harmful antigenic substances (or "allergens") such as pollen and ticks that cause allergic diseases to humans have been removed. The desire to send is getting stronger. Antigenic substances are drifting in the air or falling to the floor. In order to remove substances that are harmful to health such as antigenic substances, air conditioners equipped with various filters and inert devices have been developed.

  For example, JP-A-8-173843 discloses an air cleaning device in which a prefilter is provided upstream of a main filter of an electrostatic precipitator. The filter element of this pre-filter can remove pollen and spores of several μm or more, and the main filter of the electrostatic precipitator is virus, soot, tobacco smoke having a particle size of 0.001 μm to several tens μm. Etc. can be removed.

  Japanese Patent Laid-Open No. 6-154298 discloses an apparatus equipped with an ultraviolet irradiator as an apparatus for inactivating pollen allergens. In this apparatus, it is disclosed that pollen allergens can be made harmless to the human body by irradiating cedar pollen collected by a filter with ultraviolet rays having a certain wavelength with a certain irradiation energy.

  Japanese Patent Application Laid-Open No. 2000-111106 discloses an air cleaner including an ultraviolet lamp capable of irradiating ultraviolet rays inside the apparatus and a dust collecting filter capable of collecting fine objects. This air cleaner generates ultraviolet rays including a wavelength having a strong sterilizing action and a wavelength for generating ozone from an ultraviolet lamp. The ultraviolet rays sterilize and deodorize air containing fine substances such as bacteria and pollen with ultraviolet rays and ozone. On the other hand, the air containing ozone passes through the dust collection filter and is discharged into the room, and the ozone discharged into the room directly sterilizes and deodorizes the room air.

  Furthermore, Japanese Patent Application Laid-Open No. 7-807 discloses a pollen processing apparatus having a thermostatic chamber in which the inside is held at 65 ° C. or higher by a heating means comprising a heating wire. In this processing apparatus, pollen contained in the air is heat-treated inside the thermostatic chamber to denature the antigenic protein contained in the pollen and then discharged from the exhaust port.

In addition to killing fines and the like contained in the air by the mechanical or electrical method as described above, a prophylactic method using drugs such as putting a vaccine on the human body has been proposed.

(Constitution)
The air conditioner based on this invention is demonstrated with reference to FIGS. FIG. 1 is a cross-sectional view of an indoor unit among separate air conditioners that can generate both positive and negative ions according to the present invention. FIG. 1 is a cross-sectional view taken along a cross section perpendicular to the longitudinal direction of the indoor unit. This air conditioner is arranged and used above a wall of a room.

  Inside the main casing 4, a heat exchanger 2 for exchanging heat of air passing through the inside is disposed. In this embodiment, a plurality of heat exchangers 2 are arranged. For example, a cooling medium flows in the heat exchanger 2.

  A filter guide 5 is formed in the main body casing 4 from the front side to the upper side of the main body casing 4. A filter 7 is inserted into the filter guide 5. A front panel 6 is formed outside the filter 7 on the front side of the main casing 4. An upper panel 9 is formed outside the filter 7 on the upper side of the main casing 4.

  Inside the main casing 4, a blower fan 3 is arranged so as to be surrounded by the plurality of heat exchangers 2. The blower fan 3 is formed to rotate by a motor (not shown). The blower fan 3 is disposed so that the longitudinal direction of the air conditioner is parallel to the rotation axis. An outlet 11 is formed below the front side of the main casing 4. The blowout port 11 communicates with a space in which the blower fan 3 is disposed. An airflow path 10 for air to flow is formed from the blower fan 3 to the outlet 11.

  In the middle of the air flow path 10, an ion generating element 12 is formed as an ion generating means. The ion generating element 12 is for generating positive ions and negative ions. The ion generating element 12 is formed near the bottom surface of the main casing 4.

  In FIG. 2, the schematic explanatory drawing of the ion generating element in this form is shown. The ion generating element in this embodiment includes a dielectric 21, a plate electrode 22, and a mesh electrode 23. The dielectric 21 is sandwiched between the plate electrode 22 and the mesh electrode 23. The plate electrode 22 is a plate-like electrode. On the other hand, the mesh electrode 23 is an electrode whose planar shape is a mesh shape (lattice shape). Each of the plate electrode 22 and the mesh electrode 23 is electrically connected to a power source 24. The power source 24 is formed so that positive and negative voltages can be alternately applied to the plate electrode 22. The mesh electrode 23 is grounded.

  As an ion generating element in this embodiment, an element having a peak-to-peak voltage between electrodes of 5 kV is used. That is, a voltage having a voltage peak of 2.5 kV in the positive voltage direction and 2.5 kV in the negative voltage direction is used. In addition, a pulse waveform voltage having a frequency of 120 Hz can be input.

  The ion generating element in this embodiment has a longitudinal direction. The ion generating elements are arranged so that the longitudinal direction thereof is parallel to the longitudinal direction of the indoor unit in FIG.

  In FIG. 1, a plurality of vertical louvers 13 are arranged on the downstream side of the position where the ion generating element 12 is arranged in the air flow path 10. The vertical louver 13 is for adjusting the horizontal direction of the air ejected from the outlet 11. The vertical louver 13 is formed in a flat plate shape so that the orientation of the main surface can be changed. For example, when air is blown out toward the front of the air conditioner, the main surface of the vertical louver 13 is parallel to the air traveling direction in the air flow path 10.

  In the airflow path 10, a lateral louver 14 is formed in the vicinity of the outlet 11. In the cross section shown in FIG. 1, two lateral louvers 14 are formed. The lateral louver 14 is for adjusting the vertical direction of the air ejected from the outlet 11. The horizontal louver 14 is formed in a flat shape so that the orientation of the main surface can be changed. That is, the lateral louver 14 is formed so that the inclination angle can be changed. In this embodiment, the lateral louver 14 is connected to a driving device (not shown) so that the tilt angle is variably controlled.

  The air conditioner according to the present embodiment is an ion ejecting means for ejecting both positive and negative ions toward the floor surface, and a floating means for levitating the antigenic substance falling on the floor surface. A blower fan and a horizontal louver formed at the outlet. That is, in this embodiment, the blower fan and the horizontal louver serve as both the ion ejection means and the levitation means.

  The air conditioner in the present embodiment has a first operation function for driving the ion generating element, the blower fan, and the lateral louver in a state where heat exchange by the heat exchanger is not performed. The first operation function includes a function of driving or stopping the blower fan, the lateral louver, and the ion generating element according to the input time. That is, the first driving function can be controlled by the timer.

  As shown in FIG. 3, the air conditioner in the present embodiment has the width direction in the cross section of the horizontal louver 14 substantially parallel to the vertical direction (the main surface of the horizontal louver is substantially parallel to the vertical direction), and is substantially vertically downward. It has an operation function to blow out air.

  FIG. 4 is an explanatory diagram of the second driving function. FIG. 4 is a cross-sectional view of the air conditioner in the present embodiment. In the second operation function, the cross-sectional area of the flow path at the outlet defined by the lateral louver 14 is reduced, and the rotational speed of the blower fan 3 is further increased. The second operation function in this embodiment functions so that the distance between the outer tips of the adjacent lateral louvers 14 is reduced, and the cross-sectional area of the air flow path at the outlet 11 is reduced. Furthermore, the rotation speed of the blower fan 3 increases.

(Function of device, effect and method of deactivating antigenic substance)
Antigenic substances targeted by the air conditioner of the present invention include pollen such as cedar, cypress or ragweed, and organisms such as ticks, which cause allergic reactions by acting on the living body, causing allergic diseases A substance that induces Antigenic substances are usually formed from proteins or glycoproteins, but their shape and size are not particularly limited, and include the molecular forms of proteins and glycoproteins themselves and their aggregates. It is. In addition, a part of the molecular form is an antigenic determinant.

  In FIG. 1, the air conditioner indoor unit is inhaled and ejected by the blower fan 3 rotating about the longitudinal direction as a rotation axis. Air is sucked from the front panel 6 disposed on the front surface of the main casing 4 and the upper panel 9 disposed on the upper surface of the main casing 4. When inhaled, the dust is removed by passing through the filter 7. The air that has passed through the filter 7 undergoes heat exchange through the heat exchanger 2. By passing through the heat exchanger 2, the air becomes warmer or cooler. In addition, when air is blown without cooling or heating, the heat exchanger 2 is in a state where heat exchange is not performed.

  The air taken into the main body casing 4 moves along the air flow path 10 through the blower fan 3. By disposing the ion generating element 12 in the middle of the air flow path 10, the air is ionized and positive ions and negative ions are formed.

In FIG. 2, in the ion generating element in this embodiment, the mesh electrode 23 is grounded, and a pulse waveform voltage is input to the plate electrode 22. When the power supply 24 is turned on, the electric field concentrates on the end face of the mesh electrode 23 and discharge occurs. In this way, the plasma region 25 is formed in the space surrounded by the mesh electrode 23. In the plasma region 25, air is ionized and both positive and negative ions are formed. The ions generated from the ion generating element in this embodiment are positive ions H ₃ O ⁺ (H ₂ O) _n (n is 0 or a natural number) and negative ions O ₂ ⁻ (H ₂ O) _m (m Is 0 or a natural number) occupies most of the ionic component.

  In FIG. 1, the air containing the ions generated by the ion generating element 12 is blown out from the blowout port 11. When blown out, the vertical louver 13 determines the blowing direction (left and right direction) in the longitudinal direction of the air conditioner, and the vertical direction blown by the horizontal louver 14 is determined.

  The method for inactivating an antigenic substance according to the present invention is achieved by bringing both positive ions and negative ions into contact with the antigenic substance. Among these positive and negative ions, even if either positive ion or negative ion is in contact with the antigenic substance alone, the antigenic substance cannot be deactivated. When both positive ions and negative ions are present in the air, and these positive and negative ions come into contact with the antigenic substance suspended in the air, the antigenic substance can be deactivated.

Specifically, by experiment, when the concentration of both positive and negative ions in the room is about 10,000 / cm ³ , the antigenic substance generated from the mite is placed in this ion atmosphere for about 15 minutes. It has been found that it can inactivate allergic reactivity. Further, it has been found that when the indoor positive / negative ion concentration is about 3000 / cm ³ , about 75% of allergic reactivity can be inactivated.

  As shown in FIG. 1, the air conditioner in the present embodiment generates positive ions and negative ions with an ion generating element 12 formed in the middle of the air flow path 10, and air containing both positive and negative ions is indicated by an arrow 30. Thus, it can blow out from the blowout port 11 continuously. Moreover, both positive and negative ions can be ejected continuously. Therefore, both positive and negative ions can be brought into contact with the antigenic substance floating in the air in the room, and the antigenic substance can be deactivated. Further, even inside the air conditioner, air can be brought into contact with an environment where the density of both positive and negative ions is very high, and the antigenic substance can be deactivated.

  In the air conditioner according to the present invention, since the levitating means is formed, the antigenic substance falling on the floor surface can be moved toward the environment where both positive and negative ions are present. As a result, both positive and negative ions can be brought into contact with the antigenic substance to inactivate it.

  FIG. 5 shows an explanatory diagram when the levitation means of the present embodiment is driven and air containing both positive and negative ions is blown toward the floor surface. FIG. 5 is a cross-sectional view of the vicinity of the floor surface. In the present specification and claims, the floor surface includes not only a floor which is a direct floor such as tatami mat, concrete and wood, but also a floor surface on which a carpet or the like is disposed. That is, the floor indicates a portion that becomes the bottom of the room. In FIG. 5, the floor surface is formed of a carpet 17.

  A large number of antigenic substances 19 are attached to the carpet 17. When air containing both positive and negative ions is blown against the floor surface, the airflow hits the yarn of the carpet 17 and the like, causing a small airflow turbulence such as a vortex and the like as indicated by an arrow 32. It flows along. When the floor surface is concrete or the like, the air flows along the floor surface while turbulent air current is generated by small irregularities on the floor surface. The antigenic substance 19 floats slightly, although it is about several mm, as shown by the arrow 36 due to this small disturbance of the airflow. Both positive and negative ions 15 generated from the ion generating element are easily extinguished by colliding with a foreign substance, and become in a molecular state without a charge. However, since the sizes of the ions 15 are several nanometers each, the antigenic substance can be brought into contact with positive ions and negative ions and deactivated by slightly floating the antigenic substance from the floor surface. Can do.

  Thus, a step of blowing air containing positive and negative ions to the floor surface, a step of floating the antigenic substance falling on the floor surface by the air, and a step of bringing positive and negative ions into contact with the antigenic substance, By including the antigenic substance falling on the floor surface can be inactivated.

  The air conditioner and the method of deactivating antigenic substances according to the present invention prevent allergic diseases for all persons without difficulty such as effects due to individual differences as in the case of drug prevention. Can do. Further, unlike the pressure loss caused by clogging of the filter for removing the antigenic substance, the basic function of the apparatus is not affected and the antigenic substance can be deactivated. In addition, replacement and cleaning of the above-described filter are unnecessary, and maintenance is easy. Furthermore, the antigenic substance falling on the floor can be deactivated.

  In this embodiment, a blower fan for ejecting air from the outlet toward the floor and a lateral louver formed at the outlet are formed as the ion ejecting means and the floating means. By adopting this configuration, it is possible to easily form the ion ejection means and the levitation means. In this embodiment, the blower fan and the horizontal louver have the functions of the levitation means and the ion ejection means. However, the present invention is not limited to this configuration, and the levitation means and the ejection means may be formed separately and independently. Good. For example, the levitation means and the ion ejection means may each have a blower fan.

  As levitation means, air is used so that the wind speed on at least a part of the floor surface is 0.5 m / s or more when used in a room of the standard size of the largest room among the rooms to be used. It is preferable to form means capable of blowing air. For example, in the case of an air conditioner used in a room with a size of 6 to 8 tatami, when used in a room with a standard size of 8 tatami, the wind speed on the floor surface is 0.5 m / s or more. In addition, it is preferable to form a blower fan and a horizontal louver. By adopting this configuration, it is possible to easily form a levitating means with excellent performance.

  In a domestic air conditioner, the horizontal louver jets the air in a direction within a range of −90 ° to −30 ° when the horizontal direction is 0 ° and the vertical downward direction is −90 °. In addition, the blower fan is preferably formed such that the wind speed at the outlet is 3 m / s or more and 10 m / s or less. By adopting this configuration, the antigenic substance that has fallen on the floor surface can be efficiently lifted and inactivated by normal use at home. Note that the wind speed at the outlet may be 3 m / s or less or 10 m / s or more as long as the antigenic substance falling on the floor can be lifted. Further, the angle of the horizontal louver may be operated within a range of approximately 0 ° in the horizontal direction to approximately −90 ° in the downward direction in the vertical direction. This is because, if the height of the air outlet of the air conditioner from the floor surface is different, the wind speed and the air blowing angle required to lift the antigenic substance are also different. For example, in many fan heaters, the outlet is often formed near the floor. In such a fan heater, the angle of the horizontal louver is preferably close to the horizontal direction, and the wind speed at the outlet is high. Even if it is smaller than the air conditioner attached to the place, the antigenic substance can be raised.

  The position at which the ion generating element 12 is disposed is not particularly limited as long as it is a position in contact with the air ejected from the air conditioner, but is preferably disposed near the outlet 11. For example, as in the present embodiment, the ion generating element 12 is preferably arranged on the way from the blower fan 3 toward the outlet 11 in the airflow path 10. A part of the positive and negative ions generated by the ion generating element 12 disappears due to recombination or collision with the main body casing 4 or the longitudinal louver 13. Therefore, it is preferable that the formed positive and negative ions can be ejected toward the room without being brought into contact with the main body casing or the like by being put on the airflow. By arranging the ion generating element 12 in the vicinity of the outlet 11 as in the present embodiment, both positive and negative ions generated by the ion generating element 12 can be quickly ejected from the position with few obstacles through the outlet 11 quickly. it can. As a result, both the formed positive and negative ions can be efficiently released.

  The number of ion generating elements to be formed is not limited and may be one or two or more. Further, in this embodiment, as the ion generating means, one electrode is a grid mesh electrode and the other electrode is a flat plate. However, the present invention is not particularly limited to this, and water molecules in the air are used. As long as it can form positive and negative ions by ionizing or dissociating oxygen or oxygen molecules. In particular, as the ion generating means, in addition to the creeping discharge element, all discharge forms of ion generating means such as a corona discharge element can be used. Further, the shape and material of the electrode of the discharge element are not particularly limited, and any shape or material that can generate both positive and negative ions can be selected. For example, a needle-shaped electrode can be used as the electrode shape. The applied voltage required for generating both positive and negative ions depends on the structure of the ion generating element, but the peak to peak voltage between the electrodes is 2 to 10 kV, preferably 3 to 7 kV. Can be used.

  The air conditioner in the present embodiment has a first operation function for driving the ion generating element, the blower fan, and the lateral louver in a state where heat exchange by the heat exchanger is not performed. That is, both positive and negative ions can be generated in a blown state without cooling or heating, and the positive and negative ions can be ejected into the room by adjusting the blowing angle with the lateral louver. By adopting this configuration, the antigenic substance present in the room can be deactivated even in a period when cooling or heating is not used, and the air conditioner according to the present invention can be used regardless of the seasons. .

  The first operation function includes a function of driving or stopping the ion generating element, the blower fan, and the lateral louver according to the input time. That is, the first driving function can be controlled by the timer. By adopting this configuration, the air conditioner of the present invention can be driven for a certain period according to the automatically input time. For example, when set to stop driving after 30 minutes and stop after 3 hours, the air conditioner of the present invention automatically drives when no one is in the room, Can be deactivated.

  Moreover, the air conditioner based on this invention has the function to drive | operate with a 1st driving | operation function only when there is no person in a room using a human sensor etc. instead of driving according to the input time. It is preferable. By adopting this configuration, the antigenic substance can be automatically deactivated when there is no person in the room. These driving functions are preferably selectable by a selection button or the like. For example, it is preferable that the first operating state is named as an allergen repelling mode and is configured to be executed with one button of the remote controller. By adopting this configuration, it is not necessary to set a timer and the convenience is improved.

  The horizontal louver in this embodiment is formed so that the inclination angle can be changed continuously. By adopting this configuration, high-concentration positive and negative ions can be released toward the entire room, and the antigenic substance in the room can be uniformly deactivated. Further, as shown in FIG. 3, the width direction in the cross section of the horizontal louver 14 is substantially vertical (the main surface of the horizontal louver is substantially parallel to the vertical direction), and the vertical direction downwards as shown by the arrow 31 from the outlet 11. Has an operation function in which air is discharged. By adopting this configuration, air containing both positive and negative ions can be brought into contact with the floor surface at a short distance, and antigenic substances falling on the floor surface can be efficiently deactivated. The lateral louver may be fixed so as to eject air from the outlet toward the floor surface.

  The air conditioner in this embodiment was placed in the laboratory, and a performance test was performed when the operation was performed using the operation function of releasing air downward in the vertical direction shown in FIG. As test contents, the concentration of positive and negative ions present at each position in the room was measured.

  FIG. 6 shows the test results. The laboratory 20 has a length of 3600 mm and a height of 2400 mm in cross section. The laboratory has a width of 2400 mm and a size corresponding to a room of approximately 6 tatami mats. The indoor unit 1 of the air conditioner was disposed at a height of 2200 mm in the center of the wall surface in the width direction of the laboratory. In the measurement of the ion concentration in the laboratory, a total of 15 points were measured at intervals of 600 mm in the length direction and at intervals of 600 mm in the height direction along the center cross section in the width direction of the laboratory. Both positive and negative ions were measured after the air conditioner had been operated for about 60 minutes to stabilize the ion concentration in the laboratory. In FIG. 6, the upper numerical value of each measurement point 28 is the positive ion concentration, and the lower numerical value is the negative ion concentration.

  In the performance test, the air conditioner was set to a strong wind mode (by rotating the blower fan fast). At this time, the wind speed at the outlet was 6 m / s or more and 8 m / s or less. The air ejected from the outlet is directed to the floor as indicated by an arrow 33 by the action of the lateral louver. After reaching the floor, it flows along the floor. Thereafter, as indicated by an arrow 34, the unit returns to the indoor unit 1 along the inner wall of the laboratory. Thus, an annular flow is generated in the laboratory.

As shown in FIG. 6, in the vicinity of the center of the room, the concentration of both positive and negative ions is secured at least 3000 / cc. Therefore, the antigenic substance staying inside the room can be quickly deactivated. In the vicinity of the floor surface, the wind speed was in the range of 0.5 to 1 m / s, and the concentration of both positive and negative ions was about 3000 / cm ³ .

As a result of the test, since the concentration of both positive and negative ions near the floor surface is about 3000 / cm ^3, about 70% of the antigenic substance existing near the floor surface can be deactivated in about 15 minutes. In an actual use environment, it is considered that 70% or more of the antigenic substance can be inactivated because the operation is performed for a longer time. Thus, the air conditioner based on this invention can deactivate the antigenic substance of the whole room in a short time. Moreover, the antigenic substance which has fallen on the floor surface can also be deactivated.

  In the above test, the wind fan is rotated at a high speed to perform a strong wind operation. The air conditioner of the present invention preferably has a function of increasing the rotational speed of the blower fan more than the normal strong wind operation in order to make the antigenic substance falling on the floor surface more strongly. It is preferable that air can be ejected with an air volume of about 1.5 to 2 times that of strong wind operation in a normal air conditioner. In this case, a strong wind causes a large flow of air in the room, and the antigenic substance flies into the room or the sound of the air conditioner is noisy. However, it can be used by using the first operating function. The antigenic substance can be deactivated while the person is out. If there is no person in the room, there is no problem even if the antigenic substance flies in the room, and there is no problem even if the blowing fan rotates at a high speed and a loud sound is generated. The amount of air that can be blown is not limited to the range of the present embodiment, and the blowable range may be further expanded, for example, about 1.1 to 3 times.

  As shown in FIG. 4, the air conditioner in the present embodiment has a second operation in which the cross-sectional area of the flow path at the outlet 11 defined by the lateral louver 14 is reduced and the rotational speed of the blower fan 3 is further increased. It has a function. By adopting this configuration, it is possible to blow at a higher pressure and higher speed toward the floor surface, and the effect of floating the antigenic substance falling on the floor surface is increased. For example, antigenic substances present in the back of carpet yarn can be easily suspended and deactivated. In addition, preferably, the two lateral louvers 14 can move simultaneously while maintaining the state where the cross-sectional area of the flow path at the air outlet becomes small, and the direction of the air ejected from the air outlet 11 can be continuously changed. Is preferred. By adopting this configuration, air containing both positive and negative ions can be sprayed on the entire floor surface, and the antigenic substance in the entire room can be deactivated more reliably.

  In the form shown in FIG. 4, among the front ends in the width direction of the horizontal louver, the outer front ends approach each other, and the cross-sectional area of the flow path at the outlet is small. The tips may be close to each other, or a movable shielding plate may be provided in the vicinity of the blowout port so that the cross-sectional area of the flow path is reduced.

  Moreover, it is preferable that the air conditioner based on this invention is formed so that not only a horizontal louver but a vertical louver can drive continuously and a jetting direction can be changed. By driving the vertical louver, the direction of the air in the lateral direction (left-right direction) can be changed, and the antigenic substance is strongly lost at a position desired by the user, such as a specific position on the floor. You can make it live.

  Further, the ion generating means is not limited to the operation of blowing air, but may have an operation function of generating both positive and negative ions at the same time while performing cooling or heating. By adopting this configuration, the antigenic substance present in the air or on the floor surface can be continuously deactivated even during cooling or heating.

  In the above description, the air conditioner has been described. However, the present invention is not particularly limited to this embodiment, and the present invention can also be applied to a fan heater such as a gas fan heater or an oil fan heater. For example, as in the above embodiment, an ion generating element as an ion generating means may be disposed in the vicinity of the blowout port so that air containing both positive and negative ions can be blown out from the blowout port of the fan heater. As a levitation means, a lateral louver may be disposed in the vicinity of the outlet and formed so as to blow air toward the floor surface.

  Further, the present invention can also be applied to other air conditioning equipment and equipment that does not have a function of air conditioning. For example, the present invention can be applied to an air cleaner, a fan, a cold air fan, a dehumidifier, and the like. Furthermore, the present invention is not limited to home air conditioners, and can be applied to large air conditioners for business use. Thus, the present invention can be applied to all air conditioning equipment.
