[0010]

Embodiments of the present invention will be described below. FIG. 1 is an explanatory diagram showing the configuration of the present embodiment. The toilet deodorizing apparatus of the present embodiment includes a collection block 10 and a deodorizing block 1.
And 4. The collection block 10 has a suction part 13 that opens behind the toilet 11 and the deodorization block 1.
4 by a flexible duct 22.
The deodorizing block 14 has an air path having the suction port 15 and the air outlet 16 at both ends. In the air path, a blower 18, a heater 19, an adsorbent 20, and a self-heating type decomposition catalyst 21 are placed. They are arranged in order. A space 23 is provided between the adsorbent 20 and the self-heating type decomposition catalyst 21. In addition, a control circuit 26 for controlling the energization of the blower 18, the heater 19, and the self-heating type decomposition catalyst 21 is disposed above the deodorizing block 14. In the configuration shown in FIG. 1, the deodorizing block 14 is arranged in front of the toilet 11, but there is no problem even if it is arranged beside the toilet 11 or behind the toilet 11. . Further, the collection block 10 is not limited to the toilet seat 12 but may be a space around the toilet 11 or a space behind the toilet 11 as long as the location opens into the toilet 11.

In this embodiment, zeolite is used as the adsorbent 20. The self-heating type decomposition catalyst 2
Reference numeral 2 denotes a configuration in which, for example, platinum or an oxide is applied to the surface of the heating heater, which has a very high decomposition performance.

In this embodiment, the deodorizing block 14 is provided with a room temperature detecting means 24 such as a thermistor and a human body detecting means 25 such as an infrared sensor, an ultrasonic sensor or a seat switch. Detection information of the room temperature detecting means 24 and the human body detecting means 25 is transmitted to a control circuit 26.

The operation of this embodiment will be described below. When the user enters the toilet, the human body detecting means 25 detects the presence of the human body and transmits this information to the control circuit 26.
Upon receiving this information, the control circuit 26 starts operating the blower 18. When the blower 18 starts operating, the toilet 11
The air containing the odor is sucked into the deodorizing block 14 from the suction unit 13 through the flexible duct 22. The sucked air is purified by the odor components adsorbed by the adsorbent 20. The purified air is supplied to the outlet 16
From the toilet space.

When the user sits on the toilet seat 12, the inside of the toilet 11 is already in a negative pressure range, and the odor in the toilet is
An attempt is made to diffuse out of the toilet 11 from a part in front of the toilet 11 and a gap between the toilet 11 and the toilet seat 12. However, in the present embodiment, the toilet 11
The odor is sucked together with the flow of the air drawn in from the suction section 13 provided in the vicinity of the place where the odor is generated. Therefore, the user does not feel a deep odor in the stool, and the stool can be used.

If the deodorizing operation is repeated and the adsorption hardening is reduced by the odor component adsorbed by the adsorbent 20,
At an appropriate timing, the heater 19 and the self-heating type decomposition catalyst 2
1 is energized. The self-heating type decomposition catalyst 21
The heater has a configuration in which, for example, platinum or an oxide is applied to the surface of the heating heater, and has a very high odor component decomposition performance. When the heater 19 is energized, high-temperature air comes into contact with the adsorbent 20, and the adsorbent 20 is adsorbed and the components are desorbed. The deodorized odor component is decomposed by the self-heating type decomposition catalyst 21 and exhausted from the outlet 16 as odorless air. Thus, the adsorbent 20 is activated and recovers the adsorbing power.

At this time, in this embodiment, the control circuit 26 sets the suction air volume of the blower 18 from 0.15 m ³ / min to 0.25 m ³ / min. FIG.
FIG. 9 is a characteristic diagram showing a result of a decomposition treatment performed by sucking CO gas using the apparatus of the present embodiment. At the time of this experiment, the relationship between the suction air volume and the feeling of cool air was simultaneously shown using 14 subjects. As a result of this experiment, the suction air volume was 0.25 m
^{When the} rate is ³ / min or less, all of the test subjects do not feel a feeling of cold wind. Also, the suction air volume is 0.15 m
When the rate is set to ³ / min or more, the CO gas trapping efficiency can be made almost 100%. Therefore, in the present embodiment, as described above, the control circuit 26 sets the suction air volume of the blower 18 from 0.15 m ³ / min to 0.25 m ^3.
/ Min.

Therefore, according to the present embodiment, a deodorizing apparatus is realized in which the user does not feel a feeling of cold wind.

In this embodiment, the room temperature detecting means 24 is used. If the room temperature exceeds 30 ° C., cooling is rather required, and the setting of the suction air volume is meaningless. Therefore, in this embodiment, when the room temperature detected by the room temperature detecting means 24 is lower than 30 ° C., the control circuit 26 sets the suction air volume of the blower 18 from 0.15 m ³ / min to 0.25 m ³ / min as described above. If the room temperature exceeds 30 ° C., set the suction air volume from 0.25 m ³ / min to 0.4
m ³ / min. The room temperature is 30 ° C
In the case of exceeding, the setting of the amount of suction air is increased to realize a toilet deodorizing device capable of collecting odor at high speed.

Although not particularly shown, the deodorizing block 14 is supplied with a suction air volume of 0.15 m ³ / min to 0.2 m ² / min.
When there is provided a selection means for selecting a normal operation of 5 m ³ / min or a rapid operation of 0.25 m ³ / min to 0.4 m ³ / min, for example, when the selection means can be operated by a user, The user can switch between normal operation and rapid operation by operating the selection means according to the situation,
This makes it possible to realize a convenient toilet deodorizing device.

In this embodiment, when the room temperature detected by the room temperature detecting means 24 falls below, for example, 20 ° C., the control circuit 26 receives a signal indicating the presence of a human body from the human body detecting means 25 and receives a self-heating type signal. The power is supplied to the decomposition catalyst 21. For example, in winter when the temperature of the toilet space 24 is low, the wind blown out from the outlet 16 is set to a warm wind of about 40 ° C. Conversely, in summer when the temperature rises, the power supply to the self-heating type decomposition catalyst 22 is stopped and only the blower 18 is operated. That is, separately from the activation of the adsorbent 20, the heater function of the self-heating type decomposition catalyst 21 can be used for heating. Accordingly, it is possible to heat the inside of the toilet with a simple configuration without providing a special heater for heating, and to realize a user-friendly toilet deodorizing apparatus.

In this embodiment, although not particularly shown, the outlet 16 can be connected to the outside of the toilet. In other words, this configuration can be realized by connecting, for example, a flexible duct to the air outlet 16 and arranging the distal end of the duct outside the toilet. With this configuration, since the adsorbed odor can be exhausted to the outside of the toilet, there is no need to provide a step of decomposing the odor component adsorbed by the adsorbent 20, and a compact toilet deodorizing apparatus can be realized.
