In this embodiment, the deodorizing means 42 is constituted by an adsorbent that adsorbs odorous substances and deodorizes them. The control unit 43 is configured by a voltage variable device that adjusts a voltage supplied to the intake unit 41.

The adsorbent constituting the deodorizing means 42 includes:
A honeycomb body molded of fiber ceramic having 200 cells per square centimeter is used as a carrier for carrying a deodorizing material. As deodorizing materials, a composite oxide of manganese, copper, or cobalt (Dipoxide # 7810 Dainichi Seika Co., Ltd.) and a hydrophobic synthetic zeolite (Absents 3000 Union Showa Co., Ltd.)
To colloidal silica (Snowtex O
UP Nissan Chemical Co., Ltd. 2% (solid content ratio) is used as a binder which is carried at a density of 0.10 grams per cubic centimeter. The adsorbent included in the deodorizing apparatus of this embodiment has a volume of 850 cm ³ .

Hereinafter, the operation of the deodorizing apparatus of this embodiment will be described. FIG. 5 is an explanatory diagram illustrating a use state of the deodorizing device of the present embodiment. In this embodiment, the mat 1 constituting the deodorizing device is accommodated in the frame body 50. A sick or elderly person 51 is lying on the mat 1 using a pillow 53, and a comforter 52 is hung on the upper part.

In this state, when a switch (not shown) is turned on, the control means 43 operates to start the rotation of the suction means 41 to suck air containing an odor component from the bed 1. That is, the air sucked from the ventilation port 2a shown in FIG. 1 or FIG. The intake air enters the deodorizing section 3 from the connecting section 2b, is deodorized, and is exhausted from the exhaust port 44 of the deodorizing section 3.

At this time, in this embodiment, the ventilation path 2 is made of resin. For this reason, the ventilation path 2 has an appropriate flexibility, so that a user who uses the mat does not feel uncomfortable and is an easy-to-use deodorizing device.

At this time, the end of the resin pipe constituting the ventilation path 2 is closed, and air is taken in from the ventilation port 2a provided above the resin pipe. Further, since the lower surface and the side surfaces of the mat 1 are covered with the frame body 50, this air intake is performed only from above the mat 1. That is, the odor generated from the sick or old man 51 lying down is sucked.

At this time, the ventilation port 2a provided in the ventilation path 2 is directed upward. Therefore, the intake means 41
Is taken only from the upper part of the mat 1.
That is, the odor generated from the sick or old man 51 lying down is efficiently sucked.

In this embodiment, the ventilation path 2 is formed of a resin pipe having a circular cross section. However, the ventilation path 2 may be formed of a resin pipe having a flat cross section.
By adopting a configuration in which the cross section is a flat shape and the long sides thereof are arranged in the vertical direction, the human body on the mat 1 is less likely to feel uncomfortable, and is an easy-to-use deodorizing device.

In this embodiment, as shown in FIG. 1, the ventilation path 2 includes a plurality of branch portions, a connection portion 2b connecting the branch portions, and a connection portion connecting the connection portion 2b and the suction means 41. 2c. For this reason, the ventilation path 2 can be arranged in the entire area of the mat 1. Therefore, a deodorizing device capable of performing an efficient deodorizing process is realized.

In this embodiment, the control means 43 for adjusting the intake air flow rate of the intake means 41 has at least two stages of setting the intake air flow rate. That is, one is 0.05
those it is m ³ / min to 0.3 m ³ / min inlet air volume setting. The use of the intake air volume is the same as when the sick or elderly person 51 is lying down using the comforter 52, as shown in FIG. In other words, in this setting, the sick person or the elderly 51 does not need to feel the flow from the gap of the comforter 52, that is, it is necessary to treat the odor without giving the elderly or the sick 51 an unpleasant feeling such as a feeling of cold wind. The odor is not diffused into the room.

[0045] The other one is, 1m ³ / min or more 10m ³ /
Minutes or less. This setting is applied when the caregiver takes the comforter 52 and takes care of the elderly or sick 51. Comforter 52
In such a case, by increasing the amount of suction air by the control means 43, the body odor and excrement odor of the elderly or sick person 51 are diffused toward the caregiver. Therefore, the suction air volume is increased under the above-described conditions. By doing so, the odor component diffused into the room can be reduced, and the burden of the odor on the caregiver can be reduced. In this case, the larger the air volume is, the more effective it is. However, according to experiments by the inventors, at an air volume of 1 m ³ / min or more, the diffusion of odor to the caregiver side can be clearly reduced, and the burden of odor on nursing care Was also reduced. The upper limit is 10 m ^{3 in} actual use due to the size of the air intake, noise and the feeling of cool wind.
/ Min.

[0046] The control means 43 in this embodiment from above, and a variable configuration 0.05 m ³ / min or more 10 m ³ / min or less of the intake air volume.

At this time, in this embodiment, the control means 43
Set air amount of the intake means 41 has are those it does not matter as a 0.05 m ³ / min or more 10 m ³ / min or less to the step of applying continuously adjustable at bedtime.

In this embodiment, the interval between a plurality of resin pipes constituting the ventilation path 2 and the position of the ventilation port 2a or the density of the interval are not particularly described. The effect will be further enhanced.

Next, the deodorizing means 42 used in the present embodiment.
The operation of will be described. As an odor generated from a bedridden elderly person or a sick person, fecal odor is particularly problematic. Among the fecal odor, hydrogen sulfide is absorbed by a metal composite oxide which is a deodorizing material constituting the deodorizing means 42. Removed. Methyl mercaptan, which is generated as a body odor of bedridden elderly and sick persons, is converted into dimethyl disulfide by the catalytic action of a metal composite oxide which is also a deodorizing material constituting the deodorizing means 42, and then is converted into hydrophobic zeolite. It is removed by adsorption. Further, odors such as ammonia are also removed by the adsorption action of the hydrophobic zeolite. In addition, odors such as fatty acids and acetaldehyde generated from the human body other than fecal odor are also removed by the hydrophobic zeolite.

Hereinafter, the results of an experiment conducted to verify the above-described deodorizing effect of this embodiment will be reported. The device used in this experiment is the deodorizing section 3 shown in FIG. In this experiment, the deodorizing performance was examined using a standard gas. At this time, the intake air volume of the intake means 41 is 0.2 m.
^{At 3} / min, a mixed odor having a concentration of 50 ppm for each of ammonia, acetaldehyde, hydrogen sulfide and methyl mercaptan was used as the odor gas. As a result of measuring the odor concentration on the inflow side and the outflow side of the deodorizing section 3 under the above conditions, all the odor gases were removed by 99.9% or more.

In this example, a composite oxide of manganese, copper and cobalt (Dipiroxide # 7810, Dainichi Seika Co., Ltd.) was used as an adsorbent for sulfur compounds such as hydrogen sulfide.
Although a deodorizing material was used, a deodorizing material made of a metal oxide or a composite oxide containing at least one of manganese, copper, cobalt, and zinc has the same effect. In addition, a hydrophobic synthetic zeolite (Absentz 30) is used as an adsorbent for ammonia, acetaldehyde, and dimethyl disulfide.
00 Union Showa Co., Ltd.)
An adsorbent containing at least one of silica and alumina exhibits the same effect.

Next, the result of an experiment for verifying the effect of using a honeycomb body as an adsorbent constituting the deodorizing means 42 will be described. In this experiment, a carrier having the same shape as that of the honeycomb body was used by using foamed metal and metal fibers whose porosity was adjusted to be equal to that of the honeycomb body. On this carrier,
Manganese, copper, cobalt complex oxide (Dipoxide # 7810 Dainichi Seika) and hydrophobic synthetic zeolite (Absentz 3000 Union Showa) are in a ratio of 1: 1, colloidal silica (Snowtex OUP Nissan Chemical) 2% (Solid content ratio) as a binder, and the catalyst is supported by the same weight. In this experiment, a mixed odor with ammonia, hydrogen sulfide, methyl mercaptan, and acetaldehyde, each of which was adjusted to have a concentration of 50 ppm, was used.

As a result of this experiment, when foam metal was used, ammonia was 99.2%, hydrogen sulfide was 99.6%,
99.2% methyl mercaptan, 9 acetaldehyde
The removal rate was 9.0%. When metal fibers were used, ammonia was 98.9% and hydrogen sulfide was 99.5%.
%, Methyl mercaptan was 99.2%, and acetaldehyde was 99.0%. On the other hand, when the honeycomb body was used, as described above, the removal rate of all odors was 99.9% or more.

That is, when the honeycomb body is used, even if the porosity is the same, the efficiency of contact with the ventilated air is better than those using the foamed metal or those using the metal fiber. .

Next, the relationship between the honeycomb body, the foam metal, and the air flow rate and the pressure loss of the metal fiber of the present embodiment is examined. FIG. 6 shows the results of this experiment. As can be seen from FIG. 6, those using the honeycomb body have a lower pressure loss than those using the foamed metal or metal fiber.

As described above, by forming the adsorbent body 42 with a honeycomb body, the adsorbent body can be effectively removed and the pressure loss can be suppressed low, so that the intake means and the like can be made compact. .

Next, the change in the removal rate of the odor component when the carrying amount of the deodorizing material of the adsorbent 42 in this embodiment is changed,
The characteristics leading to breakthrough are being investigated. In this experiment, a composite oxide of manganese, copper, and cobalt (dipyroxide #
7810 (Dainichi Seika) and a hydrophobic synthetic zeolite (Absentz 3000 Union Showa) with a loading amount of 0.01 g.
Adsorbent 42 changed from 0.3 g / cm ³ to 0.3 g / cm ³
You are using The odor gas used in the experiment is
Hydrogen sulfide gas whose concentration was adjusted to 10 ppm was used.
In addition, the air flow rate is set to 0.2 m ³ / min, and the air is continuously ventilated. FIG. 7 shows the results of this experiment.

As can be understood from FIG. 7, the smaller the amount of the deodorizing material carried, the lower the removal rate and the shorter the breakthrough time. Particularly when the loading amount is 0.01 g / cm ³ , the initial removal rate is about 90%, which is extremely poor. When the loading amount is 0.05 g / cm ³ , the initial removal rate is 99% or more, and after 20 hours, the removal rate is maintained at 90% or more. From both sides, it becomes practically useful.

As described above, the loading amount of the deodorizing material was 0.05 g /
If the cm ³ or more, the initial removal rate extends also breakthrough time, the supported amount of the deodorizing material is 0.3 g / cm ³ in the adsorber 42
Is produced, more than 10% of the cells of the honeycomb are clogged by the adsorbent. This phenomenon means that the pressure loss increases. This clogged portion is where the adsorbent does not work effectively.
On the other hand, when the carrying amount was 0.2 g / cm ³ , the clogged portion was 1% or less.

[0060] From the above results, in the present example, the supported amount of the deodorizing material has a 0.05 g / cm ³ or more 0.2 g / cm ³ or less in the range, to ensure odor removal performance and no clogging good The adsorbent 42 can be as simple as possible.

(Embodiment 2) Next, a second embodiment of the present invention will be described. FIG. 8 is a side view showing the configuration of this embodiment. In this embodiment, the human body detecting means 81 is a mat 1
Is located within. The human body detecting means 81 is constituted by a pressure sensor. The detection signal of the human body detecting means 81 is transmitted to the control means 43 shown in FIG.
The control means 43 determines the presence or absence of a human body based on the detection signal of the human body detection means, and sends a signal for operating the intake means 41 shown in FIG. 4 when a human body is present. When it is recognized from the detection signal of the human body detecting means 81 that a human body does not exist, a signal for stopping the operation of the air intake means 41 is sent. That is, the control means 43 is constituted by a microcomputer or the like, and has a reference value for determining that a human body is present when a signal from the human body detection means 81 is received and a reference value for determining that no human body is present. In this case, the reference value is compared with a detection signal from the human body detecting means 81.

When the control means 43 determines that a human body is present, the control means 43 sets the intake air flow rate of the intake means 41 to 0.2 m ³ / min.

Therefore, according to the present embodiment, the air intake means 41 can be automatically operated only while a human body is present, and an economically efficient deodorizing device can be realized.

In this embodiment, a pressure sensor is used as the human body detecting means 81. However, similar effects can be obtained as long as a human body such as an infrared sensor or a temperature sensor is detected.

Inside. In this embodiment, the odor detecting means 91 is constituted by an odor sensor using tin oxide. With the above configuration, the odor detecting means 91 detects hydrogen sulfide, which is a fecal odor generated from the sick or elderly 51. The detection information of the odor detection means 91 is transmitted to the control means 43 shown in FIG. Control means 43
Is to determine the presence or absence of odor by the detection signal of the odor detection means 91, and when odor exists, sends a signal for operating the intake means 41 shown in FIG. When it is recognized from the detection signal of the odor detecting means 91 that there is no odor, a signal for stopping the operation of the suction means 41 is sent. That is, the control means 43 is constituted by a microcomputer or the like, and has a reference value for determining that odor is present when receiving a signal from the odor detection means 91 and a reference value for determining that no odor is present. In this case, the reference value is compared with a detection signal of the odor detection means 9.

When the control means 43 determines that an odor exists, the control means 43 sets the intake air flow rate of the intake means 41 at an air flow rate of 0.2 m ³ / min.

Therefore, according to the present embodiment, the suction means 41 can be automatically operated only while the odor is present, and an economically efficient deodorizing device can be realized.

In this embodiment, an odor sensor using tin oxide is used as the odor detecting means 91, but the same effect can be obtained as long as it detects other odors.
