BACKGROUND OF THE INVENTION
The present invention relates to a portable air cleaner.
[0002]
[Prior art]
Conventionally, an air purifier has mainly been a device for adsorbing or decomposing dust, bacteria, and odors in a room or vehicle to keep the air in a certain space clean. However, in a relatively large space such as a train or a conference room, or in an open space, the amount of air to be processed is enormous, which is a large-scale device or takes a long time for processing. In particular, the odor depends on the presence or absence of smoking, and there is a large difference in acceptability among individuals, making it difficult to meet individual level needs.
[0003]
[Means for Solving the Problems]
Therefore, in the present invention, clean air after treatment by the air purifier is ejected toward the user's nose and mouth, and these effects are continuously enjoyed by the user. It shall be regenerated during use, and the user will be able to spend comfortably while always feeling a refreshing sensation even in a space with a lot of odors and dust.
[0004]
DETAILED DESCRIPTION OF THE INVENTION
The invention described in claim 1 is a rechargeable air cleaner comprising a rechargeable battery, a blower for driving the rechargeable battery as a power source in a main body of the portable air purifier, and a filter provided in a part of the air passage. When the battery is not used for air cleaning, the filter is blown to regenerate the filter so that it can be used substantially continuously.
[0005]
Further, according to the first aspect of the present invention, the charging device can be efficiently charged by separating the blower from the rechargeable battery at the time of charging, supplying power directly to the blower, and blowing the air, and the regeneration of the filter also affects the charging status. Each can be achieved in good condition.
[0006]
According to the second aspect of the present invention, the operation time is relatively long compared to the time of use by operating the blower at a low air flow rate or intermittently during charge regeneration compared to the time of operation used for the air cleaning operation. Can be recharged and played more silently.
[0007]
Invention of Claim 3 connects the said portable air cleaner main body, or a part containing the said filter, and provides the said air blower and a separate air blower in the charger which charges the said rechargeable battery, Even when the rechargeable battery is being charged, stable air blowing can be achieved regardless of the state of charge, so that more stable regeneration of the filter and charging of the rechargeable battery can be realized.
[0008]
The invention according to claim 4 is provided with a heating means in an air passage that blows air to the filter during charge regeneration, and the air can be regenerated with hot air by blowing hot air. It promotes the diffusion of odor components and realizes better regeneration.
[0009]
According to a fifth aspect of the present invention, the temperature of warm air blown to the filter during charge regeneration is gradually increased as the charge regeneration progresses, so that the speed of odor component adsorbed on the filter is controlled to a predetermined amount. It is possible to achieve a better reproduction while maintaining a good environment because the odor component to be diffused can always be below a certain level.
[0010]
According to the sixth aspect of the present invention, the air volume of the warm air blown to the filter at the time of charge regeneration is increased by controlling the air volume only by increasing the air volume when the temperature of the heating means is high and suppressing the air volume when the temperature is lower. It is possible to obtain warm air at a temperature of.
[0011]
According to a seventh aspect of the present invention, the heating means is realized by refluxing the heat of the charging power supply circuit, so that hot air blown to the filter at the time of charge regeneration can be sold without providing a heat source such as a heater. It is possible to realize a portable air cleaner having a more compact and efficient charging / reproducing device.
[0012]
The invention according to claim 8 provides an odor component by disassembling and discharging the odor component desorbed from the filter by regeneration by providing a deodorization catalyst downstream of the wind passing through the filter during charge regeneration. The discharge time of the filter is reduced and the regeneration time of the filter is shortened.
[0013]
The invention described in claim 9 decomposes the odor component desorbed by regeneration from the filter with the deodorization catalyst by forming an air passage that guides the wind that has passed through the deodorization catalyst to the blowing means during charge regeneration, By repeatedly circulating inside, the filter can be regenerated without odor components being discharged.
[0014]
【Example】
Embodiments of the present invention will be described below with reference to FIGS.
[0015]
Example 1
FIG. 1 is a sectional view of a first embodiment of the present invention, and FIG. 2 is a view showing an example of its use.
[0016]
In FIG. 1, a portable air purifier main body 1 is provided with a suction port 3 and a blower port 4 in a main body outer shell 2, and an air-permeable filter 5 that covers and covers the suction port 3, and the filter 5 and the blower port. 4 and a rechargeable battery 7 as a power source for driving the blower 6. Here, the width 4a of the air blowing port 4 is substantially equal to the lower surface width 8a of a general human nose 8.
[0017]
Next, the operation will be described. As shown in FIG. 2, the portable air cleaner body 1 is used by the user with the air blowing port 4 directed toward the nose 8, or the mouth 9 and the nose 8 near the nose. The portable air purifier main body 1 passes the filter 5 having a deodorizing effect from outside air sucked from the air inlet 3 by the operation of the air blower 6, and blows out the air from the air outlet 4 through the air blower 6. Alternatively, by blowing on the mouth 9 and the nose 7 in the vicinity of the nose 8, cleaner air from which the bad odor and dust of the surrounding outside air are removed is supplied only to the user.
[0018]
FIG. 3 is a diagram showing the circuit connection of the portable air purifier. When charging, the power supply for charging the rechargeable battery 7 and the blower 6 are connected by connecting the terminal 12 of the charger 11 to the charging terminal 10. Are simultaneously supplied.
[0019]
By using the filter 5 as described above, deodorization is achieved by adsorbing the odor component to the filter 5 itself. By continuing to use the filter 5, the odor component is accumulated and gradually deodorized. Ability is reduced. Generally, the adsorbent such as the filter 5 used here maintains adsorption equilibrium with the outside air, and dissipates the odor component to the air without the odor component in a state where a large amount of the odor component is accumulated. . Therefore, it is necessary to replace the filter or reduce the odor component of the filter 5 (regeneration of the filter 5). According to the portable air cleaner of this configuration, by using the rechargeable battery 7, if the blower 6 is operated for a certain period of time (use of the portable air cleaner), it cannot be operated due to a power supply drop. This prevents excessive accumulation of the odor components of the filter 5 and simultaneously operates the blower 6 when charging the rechargeable battery 7 to vent the air without the odor components through the filter 5, thereby diffusing the odor components of the filter 5. The filter 5 can be regenerated. By performing filter regeneration together with charging, it becomes possible to continue to use the portable air cleaner.
[0020]
As described above, according to the first embodiment of the present invention, the portable air cleaner can be repeatedly used in a comfortable state.
[0021]
(Example 2)
FIG. 4 is a block diagram showing a circuit according to the second embodiment of the present invention. The configuration of the main body is the same as that of the first embodiment, but the resistor 12 is connected between the blower 6 and the charging terminal 10 as shown in FIG.
[0022]
Next, the operation will be described. As described in the first embodiment, the charging power supply to the rechargeable battery 7 and the power supply to the blower 6 are performed simultaneously by connecting the terminal 12 of the charger 11 to the charging terminal 10 during charging.
[0023]
However, the resistor 12 is installed between the charging terminal 10 and the blower 6 here, the air blow of the blower 6 is restrict | limited, and it drive | operates with an air volume lower than the air volume at the time of use.
[0024]
According to the present invention, the odor component adsorbed on the filter 5 is dissipated by blowing air during charging, and the filter 5 is regenerated. In this way, the odor component is dissipated by flowing a lower air volume than in use. It is possible to limit the speed and suppress the concentration of the odor component in the surrounding space, and by setting the concentration of the odor component to a value below the threshold perceived by humans, the present embodiment limits the air volume of the blower 6 with the resistor 12. Although this has been done, the air flow of the blower 6 is limited even by using intermittent operation by a switch, current limiting by other elements, or by means of narrowing the wind path before and after the blower 6. The same effect can be expected, and the difference in the air volume restriction limiting means does not impede the gist and effectiveness of the present invention.
[0025]
5 is an enlarged view of the charging terminal 10 portion and the vicinity of the terminal 12 on the side of the charger 11 according to the second embodiment of the present invention, and the charging terminal 10 is detachably connected to the charging terminals 10a, 10b, and 10c, respectively. It consists of terminals 12a, 12b, 12c on the side of the vessel 11.
[0026]
FIG. 6 is a block diagram showing connections in the second embodiment. The charging terminal 10a also serves as a switch at the same time, and the charging switch 13 is simultaneously opened by connecting the terminal 12a on the charger 11 side. One end of the charging switch 13 is connected to the charging terminal 10 a and the anode 7 a of the rechargeable battery 7, and the other end is connected to the positive electrode side of the blower 6. Similarly, the charging terminal 10b is connected to the positive side of the blower 6, and the charging terminal 10c is connected to the cathode 7b of the rechargeable battery 7 and the negative side of the blower 6.
[0027]
Here, the operations will be described. During charging, when the main body is set in the charger, the terminals 12a, 12b and 12c of the charger are connected to the charging terminals 10a, 10b and 10c of the main body, respectively. At the same time, the terminal 12a opens the charging switch 13, and the anode 7a of the rechargeable battery 7 and the circuit between the charging terminal 10a and the positive side of the blower 6 are disconnected. Therefore, the anode 7a of the rechargeable battery 7 is connected to the charging terminal 10a, the positive side of the blower 6 is connected only to the charging terminal 10b, and the rechargeable battery 7 and the blower 6 are connected in parallel to the charging terminal 10c. The Since the battery charger 12 supplies power to the terminals 12 a and 12 b as separate power supplies from the power supply 13, the blower 6 is powered independently of the rechargeable battery 7.
[0028]
As described above, according to the present invention, the blower 6 can efficiently charge the blower 6 by sufficiently disconnecting the rechargeable battery 7 during charging, and the blower 6 can be sufficiently driven. Can be achieved without affecting the charging status, and each can be achieved in good condition.
[0029]
(Example 3)
A third embodiment of the present invention will be described. Here, the main body is the same as in the first and second embodiments. FIG. 7 is a cross-sectional view of the charger 14 according to the third embodiment of the present invention. Reference numeral 15 denotes a charger blower, which is substantially opposed to the air inlet 3 of the main body.
[0030]
In these configurations, the operation will be described. During charging, the charger blower 15 operates simultaneously with the charging operation of the rechargeable battery 7 and blows air toward the inlet 3 of the main body 1. The blown air is exhausted from the air outlet 4 to the outside of the main body via the filter 5.
[0031]
Thus, since the charger blower 15 is provided separately from the blower 6 of the main body, there are few restrictions on the weight, size, etc., so that a sufficient air volume can be obtained and the time required for the regeneration of the filter 5 is shortened. In addition, since it does not affect the charging of the rechargeable battery, the filter regeneration and the charging of the rechargeable battery can be simultaneously performed more quickly and stably.
[0032]
Example 4
Embodiment 4 of the present invention will be described. Here, the main body is the same as in the first and second embodiments. FIG. 8 is a sectional view of the charger 16 according to the fourth embodiment of the present invention, in which 17 is a charger blower and 18 is a heater. The heater 18 is located downstream of the charger blower 17, and the downstream side thereof is substantially opposite to the air inlet 3 of the main body. Both the heater 18 and the charger blower 17 operate during the charging operation.
[0033]
The operation of the above configuration will be described. When charging the main body in the present invention, the charger blower 17 and the heater 18 are operated simultaneously with the charging operation of the rechargeable battery 7. The wind from the charger blower 17 is heated by the downstream heater 18 and is blown toward the intake port 3 of the main body 1 as warm air. The blown warm air is exhausted from the blower opening 4 to the outside of the main body via the filter 5.
[0034]
The filter 5 in normal use adsorbs odor components, but in general, the adsorption capacity of this type of adsorbent decreases with temperature, and the amount that can be adsorbed decreases. In other words, by passing warm air through the filter 5 that has adsorbed the odor component, the odor component can be easily released as compared to normal temperature. As a result, more odorous components can be released as compared to simply blowing air, so that a more regenerated state can be realized as a filter.
[0035]
(Example 5)
Next, a fifth embodiment of the present invention will be described. Here, the main body is the same as in the first and second embodiments. FIG. 9 is a cross-sectional view of the charger 19 according to the fifth embodiment of the present invention, in which 20 is a charger blower and 21 is a heater. The heater 21 is located downstream of the charger blower 20, and the downstream side thereof is substantially opposed to the air inlet 3 of the main body.
Both the heater 21 and the charger blower 20 operate during the charging operation. Reference numeral 22 denotes a temperature controller for the heater 21, which operates in conjunction with a temperature sensor 23 provided downstream of the heater 21 to control the heater 21 and adjust the temperature of the hot air to a predetermined temperature.
[0036]
The operation of the above configuration will be described. When charging the main body in the present invention, the charger blower 20 and the heater 21 are operated simultaneously with the charging operation of the rechargeable battery 7. The wind from the charger blower 20 is heated by the downstream heater 21 and is blown toward the intake port 3 of the main body 1 as warm air. The blown warm air is exhausted from the blower opening 4 to the outside of the main body via the filter 5. At that time, the temperature controller 22 operates in conjunction with the temperature sensor 23 to control the heater 21 and adjust the temperature of the hot air step by step in a preset order.
[0037]
As described in the fourth embodiment, in the present invention, the filter 5 is regenerated by passing warm air through the filter 5 to dissipate the odor component of the filter 5. Odor components will be emitted in this space. The odor component has a limit concentration (threshold value) perceived by humans by its olfaction. Even if it is in the vicinity during charging and regeneration of the charger, the odor component is not felt as long as it is below the concentration. In the present invention, the temperature controller 22 controls the heater 21 in conjunction with the temperature sensor 23, and adjusts the temperature of the hot air stepwise in a preset order to increase the odor at each time. It controls the amount of emitted components and always keeps the concentration of odorous components in the surrounding space below a threshold value, and does not cause discomfort even during filter regeneration.
[0038]
In the same configuration, the temperature controller 22 is used to control the charger blower 20, and when the temperature detected by the temperature sensor 23 is higher than a predetermined temperature, the air volume is increased, and when the temperature is low, the air volume is limited. The same effect can be obtained even if the temperature of the hot air is adjusted step by step in the order set in advance as the predetermined temperature by controlling the temperature of the hot air.
[0039]
(Example 6)
Next, a sixth embodiment of the present invention will be described. Here, the main body is the same as in the first and second embodiments. FIG. 10 is a cross-sectional view of the charger 24 according to the sixth embodiment of the present invention, in which 25 is a charger blower, 26 is a power supply circuit for supplying power to the rechargeable battery 7 and the charger blower 25. The power supply circuit 26 is located downstream of the charger blower 25, and the downstream side thereof is substantially opposite to the air inlet 3 of the main body. Both charger blowers 25 operate during a charging operation.
[0040]
The operation of the above configuration will be described. At the time of charging the main body in the present invention, the power supply circuit 26 supplies power to the rechargeable battery 7 to the charger blower 25 and at the same time generates a considerable amount of heat. In the configuration of the present invention, the wind from the charger blower 25 is first blown toward the power supply circuit 26, and after cooling the power supply circuit 26, the blower is blown toward the intake port 3 of the main body 1 and the filter 5. The air is exhausted from the blower port 4 to the outside of the main body. As the power supply circuit 26 is cooled, the wind from the charger blower 25 becomes warm air and passes through the filter 5, so that the filter 5 is regenerated to a better state as compared with the cold air. Further, since no extra heater or the like is required on the charger side, the battery can be made smaller and lighter.
[0041]
(Example 7)
Next, a seventh embodiment of the present invention will be described. Here, the main body is the same as in the first and second embodiments. FIG. 11 is a sectional view of the charger 27 according to the seventh embodiment of the present invention, in which 28 is a charger blower, 29 is a power supply circuit for supplying power to the rechargeable battery 7 and the charger blower 28. Reference numeral 30 denotes a heater located downstream of the charger blower 28, and the downstream side thereof is substantially opposite to the air inlet 3 of the main body. In the main body 1, the air blown by the charger blower 28 passes through the filter 5 through the air inlet 3 and is exhausted from the air outlet 4 to the outside of the main body. 31 is provided as a charger inlet so as to substantially cover the blower opening 4 of the main body 1. 32 is a deodorizing catalyst that promotes the decomposition of odorous components by catalytic action. Reference numeral 33 denotes an air passage connecting the deodorizing catalyst 32 and the upstream side of the charger blower 28.
[0042]
The operation of the above configuration will be described. At the time of charging the main body in the present invention, simultaneously with charging of the rechargeable battery 7 from the power supply circuit 29, the charger blower 28 and the heater 30 as necessary are operated to start blowing. This wind passes through the filter 5 through the air inlet 3 of the main body, flows into the charger air inlet 31 of the charger 27 from the air outlet 4, passes through the deodorizing catalyst 32, passes through the air passage 33, and is connected to the charger blower 28. Return.
[0043]
The odor component adsorbed on the filter 5 is dissipated by blowing air, but is decomposed through the deodorizing catalyst 32 of the charger 27. Therefore, the odor component is decomposed and the filter 5 is regenerated during charging. Further, the wind that has passed through the deodorizing catalyst 32 passes through the air passage 33 and circulates to the charger blower 28, so that the decomposition of the odor component becomes more reliable and the wind circulates to reduce the heater with less power. 30 can maintain the temperature, and even with lower power, it is possible to gradually raise the temperature by circulation, so that the filter 5 can be regenerated with a simpler configuration. It is. Although the case where the heater 30 is provided as a heat source has been described in the seventh embodiment, the same effect as that of the heater 30 is obtained by placing the power supply circuit 29 in the air path instead of the heater 30 as in the sixth embodiment. Even so, it does not depart from the spirit of the present invention.
[0044]

It promotes the emission of odor components and can be regenerated better.
[0049]
According to the sixth aspect of the present invention, by gradually increasing the temperature of the hot air blown to the filter during charge regeneration as the charge regeneration progresses, the speed of odor component adsorbed on the filter is increased by a predetermined amount. Therefore, it is possible to control the odor component to be diffused at a certain level or less, so that better reproduction can be realized while maintaining a good environment.

Thus, it is possible to obtain hot air at a constant temperature.
[0051]
According to the eighth aspect of the invention, the heating means is realized by refluxing the heat of the charging power supply circuit, so that hot air blown to the filter at the time of charge regeneration can be sold without providing a heat source such as a heater. It is possible to realize a portable air cleaner having a more compact and efficient charging / reproducing device.
[0052]
According to the invention described in claim 9, by providing a deodorization catalyst downstream of the wind passing through the filter at the time of charge regeneration, the odor component desorbed by regeneration from the filter is decomposed and discharged by the deodorization catalyst. Reduces odor component emissions and shortens filter regeneration time.
[0053]
According to the invention described in claim 10, the odor component desorbed by regeneration from the filter is decomposed by the deodorization catalyst by forming an air passage that guides the wind that has passed through the deodorization catalyst to the air blowing means during charge regeneration. In addition, by repeatedly circulating inside, the filter can be regenerated without discharging odor components.
