The method using an air purifier collects odor components after the odor generated from the human body once spreads in a room and the odor components are adsorbed on a wall or the like. In addition, there is a problem that the deodorizing efficiency is low due to the low odor.

In addition, the structure using sheets or the like containing an adsorbent is more effective than the method using an air purifier in the sense that odor components are adsorbed before the odor spreads in the room. Although it is recognized, the efficiency is still low because it is adsorbed by natural convection.

[0005]

[0013]

(Embodiment 1) A first embodiment of the present invention will be described below. FIG. 1 is a perspective view showing the configuration of the present embodiment. The mat according to the present embodiment includes a main body 1, a first ventilation passage 3 disposed in the main body 1, an intake unit 2 connected to the first exhaust passage 3, and a second ventilation unit connected to the intake unit 2. Route 4
It is constituted by and.

The main body 1 has the structure shown in FIG. A substrate 1a made of a porous material;
And a first ventilation path 3 inserted in the middle of the base material 1a. The substrate 1a has a configuration shown in FIG. That is, a thread-shaped nylon resin molded into a spring and entangled is used. Therefore, it has many hollow parts, has a porous structure as a whole as described above, and has air permeability. Also, because it is molded into a spring,
The base material 1a has elasticity. The cover 1b is made of a thick cloth and has flexibility but no air permeability. The first ventilation path 3 is made by combining resin pipes. The tip of the resin pipe is closed, and has many vents 3a. In this embodiment, the vents 3a have a diameter of 5 mm and are provided upward at intervals of 5 cm.

The first ventilation path 3 is connected to the intake means 2. In this embodiment, a sirocco fan is used as the intake means 2. However, an axial fan may be used, and there is no need to limit the type. Further, a second ventilation path 4 is connected to the intake means 2. The second ventilation path 4 is formed of a resin pipe similarly to the first ventilation path 3, and has, for example, a distal end outside the room in which the device is installed.

The operation of this embodiment will be described below. FIG. 4 is an explanatory diagram illustrating a state in which the apparatus of the present embodiment is actually used. In this embodiment, it is assumed that the sick person 10 uses this device. That is, the sick 10 is lying on the main body 1, and the comforter 11 is hung on the sick 10. In addition, 12 is a pillow. In this state, when the switch of the intake means 2 (not shown) is turned on, the intake means 2 takes in air from the first ventilation path 3 and arranges the opening 4a in the adjacent room via the partition 13 with the adjacent room. The air sucked in from the second ventilation path 4 is blown. The first ventilation path 3 is closed at an end and has a large number of ventilation ports 3a at the top. Further, the base material 1a is a cover 1
The lower surface and the side surface are covered by b. For this reason, only the airflow from the upper part where the sick person 10 is lying flows inside the porous base material 1a.
For this reason, the air sucked by the suction means 2 contains odor components generated by the sick person 10. The air containing the odor component is exhausted from the opening 4a of the second ventilation path 4 to the outside as described above.

Therefore, even if a person who cares for the sick person 10 is in the same room, the odor component generated from the sick person is inhaled by the intake means 2 and exhausted outside through the opening 4a of the second ventilation path 4. However, the extent to which the caregiver perceives the odor of the sick is very small.

In this embodiment, the ventilation holes 3a provided in the first ventilation path 3 are arranged uniformly, but, for example, they are arranged so that the places where strong odor is generated are dense. Sometimes, the effect is even greater.

(Embodiment 2) Next, a second embodiment of the present invention will be described. FIG. 5 is an explanatory diagram showing the configuration of the present embodiment. In the present embodiment, a first control unit 15 for adjusting the amount of intake air or the amount of air blown by the intake unit 2 is provided. The first control means 15 is constituted by a voltage control means for controlling a voltage supplied to the intake means 2. The intake means 2 is configured such that the lower the supplied voltage, the lower the intake air volume, and thus the amount of air blow, and the higher the supplied voltage, the higher the intake air volume or air flow.

The operation of the embodiment will be described below. As shown in FIG. 4, when the sick person 10 is sleeping, the supply voltage to the intake means 2 is reduced by the first control means 15 to reduce the intake air volume or the blow air volume of the intake means 2. It is. Therefore, the sick person 10 is less likely to feel the flow of air from the gap of the comforter 11 shown in FIG. In other words, the degree to which the elderly and the sick feel cold wind and discomfort is reduced.

According to the inventors' experiments, the settings of the intake air amount or blowing air amount of the intake means 2, if 0.1 m ³ / min to 0.3 m ³ / min, no discomfort or cold sensation, also Since the comforter 11 is used, the odor is not diffused into the room.

As shown in FIG. 5, the comforter 1
When the caregiver takes care of an elderly person or a sick person in a state where 1 is removed, the setting of the intake air volume or the ventilation air volume of the intake means 2 by the first control means 15 is increased. That is, in the experiment by the inventors, when the setting is about 3 m ³ / min, the odor generated from the sick person 10 is not diffused into the room. In this case,
The more the set air volume of the intake means 2 is, the more effective it is. However, actually, the degree of the noise generated from the intake means 2 and the
It is limited by the size of the feeling of cold wind felt by 0. For this reason, as described above, the optimal air flow rate of the intake means 2 is about 3 m ³ / min. In this state, the diffusion of the odor to the caregiver side is very small, and is of little concern.

As described above, according to the present embodiment, the first control means 15 controls the intake air flow rate or the blown air flow rate of the intake means 2, so that it is possible to selectively use the apparatus at bedtime and at the time of nursing care. Thus, a more convenient device can be realized.

(Embodiment 3) Next, a third embodiment of the present invention will be described. FIG. 6 is an explanatory diagram showing the configuration of the present embodiment. In the present embodiment, the air intake unit 2 is
The adsorbent 21 as a deodorizing means, the catalyst body 22, the regeneration heater 23, the first control means 15, and the second control means 24
It is constituted by.

The blower unit 20 uses a sirocco fan or an axial fan as in the above embodiments. The deodorizing means 21 uses a honeycomb-shaped zeolite as a carrier and an adsorbent having a configuration in which manganese oxide is supported on the zeolite carrier. The catalyst body 22 is disposed above the adsorbent 21, and in this embodiment, Fe,
A catalyst heater in which 0.05 g of a noble metal catalyst such as Pt or Pd is supported on a corrugated expanded metal heater made of heat-resistant steel containing Cr as a main component. Also, electrode terminals (not shown) are provided at both ends of the expanded metal,
By applying a voltage between the electrode terminals, the catalyst body 22 itself generates heat at a catalyst activation temperature of 400 ° C. The regeneration heater 23 is disposed below the adsorbent and uses a nichrome heater. Further, the first control unit 15 is configured by a voltage adjusting unit that adjusts the voltage supplied to the blower unit 20, as described in the second embodiment. The second control means 24 has a function of controlling the power supply time and power supply cycle to the regeneration heater 23 and the catalyst body 22, and is constituted by a microcomputer or the like.

In this embodiment, the second ventilation path described in each of the above embodiments is not connected to the intake means 2.

Further, in the present embodiment, the adsorbent 21 serving as the deodorizing means is arranged in the suction means 2, but it is not necessary to particularly arrange in the suction means 2.
In other words, there is no problem in arranging the blower unit 20 anywhere in the ventilation path that takes in air from the first ventilation path 3.

The operation of this embodiment will be described below. When a switch (not shown) is turned on and the blower 20 starts operating, the odor component generated from the sick person is sucked into the suction means 2 from the first ventilation path 3 as described in each of the above embodiments. You. This odor component is adsorbed by the adsorbent 21, becomes odorless, and is exhausted from an exhaust port (not shown). Further, the first control means 15 controls the blowing unit 2
Adjusting the voltage to be supplied to the air blower 2
It is possible to adjust the amount of air blown to zero and to adjust the degree to which odor is sucked.

At this time, if used repeatedly, the adsorbent 2
No. 1 loses its activity due to the adsorbed odor component. The desorbed adsorbent 21 can be activated again by energizing the regeneration heater 23 and contacting high-temperature air. In the activation step, if the catalyst 22 is energized, the catalyst 22 adsorbs and decomposes odor components separated from the adsorbent 21 by activation.

FIG. 7 is a timing chart showing a control program for the activation process of the microcomputer constituting the second control means 24. Second control means 24
Performs the activation process of the adsorbent 21 once a day. In this activation step, the energization of the catalyst body 22 is started at the same time as the blowing section 20 is stopped, and the regeneration heater 23 is energized two minutes after this. In other words, the catalyst 22 is heated first, the average temperature of the adsorbent 52 is set to 400 ° C., and the odor component desorbed from the adsorbent 21 is removed by the noble metal catalyst having the catalyst 22. It is intended to be able to be decomposed.

In this way, the power supply to the regeneration heater 23 is stopped after 30 minutes, and the power supply to the catalyst body 22 is stopped after 3 minutes, and the blower unit 20 is operated again. That is, high-temperature air from the regeneration heater 23 is brought into contact with the adsorbent 21 for 30 minutes to desorb the odor component adsorbed by the adsorbent 21, and the odor component is decomposed by the catalyst 22. is there. The odorless gas is discharged from the outlet of the intake means 2 (not shown) by natural convection. After the disassembly process is completed, the blower unit 20 is operated again to inhale the odor component generated by the sick person again.

As described above, by automatically activating the adsorbent 21 using the second control means 24,
For example, the adsorbent can be regenerated when no deodorization is required, such as at midnight around 2:00 am, and a mat that is easy to use can be realized.

As described above, according to the present embodiment, since the adsorbent 21 as the deodorizing means is arranged in the middle of the first ventilation path 3, the mat which can reduce the amount of odor components exhausted to the outside can be reduced. Is realized. By providing the deodorizing means in the middle of the ventilation path, it is not necessary to put the exhaust port out of the room or outside, and the device can be made compact.

Further, by using the adsorbent 21 for the deodorizing means, a high performance deodorizable mat can be realized.

Further, since the regenerating heater 23 is used as a regenerating means for regenerating the adsorbent 21, the mat capable of regenerating the adsorbent 21 and repeatedly using the adsorbent 21 is realized.

The regenerating means comprises a heater and a catalyst to realize a mat which decomposes odor components generated during regenerating and does not exhaust to the outside.

Further, the activation step of the adsorbent 21 is executed by the second control means 24, and the regeneration of the adsorbent 21 can be executed particularly when deodorization is not required. It can be realized.

(Experimental Example 1) The results of experiments performed to verify the effects of the above embodiments will be reported below. In the first experiment, the performance of the adsorbent 21 was evaluated. That is, a predetermined concentration of odor gas is supplied to the adsorbent 21, the amount of the odor gas contained in the exhaust gas after passing through the adsorbent 21 is measured, and the adsorption performance of the adsorbent 21 is evaluated. Is what it is.

The adsorbent 21 used in this experiment has a volume of 1.2 liters. As the odor gas, acetic acid is used as a representative of body odor, and hydrogen sulfide and ammonia are used as a representative of fecal odor. Also, the supply of the gas to the adsorbent 21 is performed only once, and the one-pass removal rate is measured.
The initial concentration of each odor gas is set to 50 ppm,
The blowing air volume of the blowing unit 20 is 0.2 m ³ assuming bedtime.
/ Min.

As a result of this experiment, the odor gas removal rate was 99.5% for acetic acid, 99.8% for ammonia, and 99.6% for hydrogen sulfide. As a comparative experiment, the adsorbent 21
Used was a configuration using only zeolite. At this time, the removal rate of hydrogen sulfide was 10%. That is, the adsorbent 21 of this embodiment has a sufficient adsorption performance.

At this time, as described with reference to FIG. 4 or FIG. 5, when a use experiment was conducted in an actual use state, no odor from the human body was perceived indoors, and the effect was recognized even in actual use. Can be

(Experimental Example 2) Next, the results of an experiment for verifying the validity of the control program of the second control means 24 described in the third embodiment will be reported.

First, a mixed gas of acetic acid, hydrogen sulfide, and ammonia was passed through the adsorbent 21 for 24 hours at a flow rate of 0.2 m ³ / min with both the regeneration heater 23 and the catalyst 22 turned off. At this time, each gas concentration is set to 1 ppm. Next, the ventilation was stopped, and only the regeneration heater 23 was energized. The adsorbent 21 receives heat from the regeneration heater 23, and the adsorbed gas gradually desorbs. Thus, 5
The concentration of each gas was measured every minute at an exhaust port (not shown). As a result, 5 to 5
After 10 minutes, a maximum gas concentration of 8 ppm was detected,
No gas is detected after 25 minutes.

Therefore, the energizing time of the regeneration heater 23 is 1
It can be confirmed that the effect is obtained in about 30 minutes per day.

Next, similarly, the regeneration heater 23, the catalyst body 22
, A mixed gas of acetic acid, hydrogen sulfide and ammonia was passed at a rate of 0.2 m ³ / min for 24 hours. The gas concentration at this time is 1 ppm each. Thereafter, the ventilation was stopped, the catalyst 22 was energized, and two minutes later, the regeneration heater 23 was energized. In this state, the exhaust gas concentration is similarly measured at the exhaust port. As a result of this measurement, no gas was detected from the initial stage until 30 minutes later.

This is because, even if the regeneration heater 23 is energized and the gas adsorbed from the adsorbent 21 is desorbed, each gas is oxidized and decomposed by the action of the catalyst 22.

Also, in an experiment of actual use using the above means, the ventilation section 20 was stopped after ventilation for 24 hours, and
When the activation step is performed for a minute, no odor is sensed from the exhaust port during the activation step.
