【Example】
Examples of the present invention will be described below. FIG. 1 is an explanatory diagram showing the configuration of this embodiment. The toilet deodorization apparatus according to the present embodiment includes a collection block 10 and a deodorization block 14. The collection block 10 has a suction portion 13 that opens behind the toilet 11 and is connected to the deodorization block 14 by a flexible duct 22. The deodorizing block 14 is an air passage having both the suction port 15 and the air outlet 16 at both ends, and the blower 18, the heater 19, the adsorbent 20, and the self-heating decomposition catalyst 21 are placed in the air passage. Arranged in order. A space 23 is provided between the adsorbent 20 and the self-heating decomposition catalyst 21. A control circuit 26 for controlling energization of the blower 18, the heater 19, and the self-heating decomposition catalyst 21 is disposed above the deodorizing block 14.
[0011]
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. . The collection block 10 is not limited to the toilet seat 12 and may be a space around the toilet 11 or a space behind the toilet 11 as long as it is a location that opens in the toilet 11.
[0012]
In the present embodiment, zeolite is used as the adsorbent 20. The self-heating type decomposition catalyst 21 has a structure in which, for example, platinum or oxide is applied to the surface of the heating heater, and has a very high decomposition performance.
[0013]
In the present embodiment, the deodorizing block 14 is provided with a room temperature detecting means 24 made of a thermistor or the like and a human body detecting means 25 made of an infrared sensor, an ultrasonic sensor, a seating switch or the like. Detection information of the room temperature detection means 24 and the human body detection means 25 is transmitted to the control circuit 26.
[0014]
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 the operation of the blower 18. When the blower 18 starts operation, the air containing the odor in the toilet 11 is sucked into the deodorizing block 14 from the suction portion 13 through the flexible duct 22. The sucked air is purified by adsorbing odor components by the adsorbent 20. The purified air is discharged from the outlet 16 into the toilet space.
[0015]
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 from a part of the front of the toilet 11 and a gap between the toilet 11 and the toilet seat 12. 11 Try to spread out. However, in this embodiment, the odor is sucked from the suction portion 13 provided in the vicinity of the place where the odor is generated, together with the flow of air drawn into the toilet 11 from the gap around the toilet 11 from the toilet space. Is. For this reason, the user does not feel an unpleasant odor during the stool, and the stool can be made.
[0016]
When this deodorizing operation is repeated and the adsorption effect is reduced by the odor component adsorbed by the adsorbent 20, the heater 19 and the self-heating decomposition catalyst 21 are energized at an appropriate timing. The self-heating decomposition catalyst 21 has a structure in which, for example, platinum or oxide is applied to the surface of the heating heater, and has a very high decomposition performance of odor components. When the heater 19 is energized, high-temperature air comes into contact with the adsorbent 20, and the odor component adsorbed by the adsorbent 20 is released. The detached odor component is decomposed by the self-heating decomposition catalyst 21 and exhausted as odorless air from the outlet 16. Thus, the adsorbent 20 is activated and recovers the adsorption power.
[0017]
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. 2 is a characteristic diagram showing the result of the decomposition process by sucking CO gas using the apparatus of this example. During this experiment, 14 subjects were used to simultaneously show the relationship between the suction air volume and the feeling of cold air. As a result of this experiment, when the suction air volume is 0.25 m ³ / min or less, all of the subjects do not feel the feeling of cold air. Further, when the suction air volume is 0.15 m ³ / min or more, the CO gas collection efficiency can be made almost 100%. Therefore, in this 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.
[0018]
For this reason, according to the present Example, the deodorizing apparatus which a user does not feel a cold wind feeling is implement | achieved.
[0019]
In this embodiment, the room temperature detecting means 24 is used. If the room temperature exceeds 30 ° C., cooling is rather necessary, and the setting of the suction air volume is meaningless. Therefore, in the present embodiment, when the room temperature detected by the room temperature detecting means 24 is less than 30 ° C., the control circuit 26 changes the suction air volume of the blower 18 from 0.15 m ³ / min to 0.25 m ³ / min as described above. When the room temperature exceeds 30 ° C., the setting of the suction air volume is controlled from 0.25 m ³ / min to 0.4 m ³ / min. Thus, when room temperature exceeds 30 degreeC, the setting of suction | inhalation air volume is increased and the toilet deodorizing apparatus which can collect an odor at high speed is implement | achieved.
[0020]
Although not specifically shown, the deodorizing block 14 is operated in a normal operation with a suction air volume of 0.15 m ³ / min to 0.25 m ³ / min, or with a rapid speed of 0.25 m ³ / min to 0.4 m ³ / min. For example, when a selection means for selecting whether to drive is provided and the user can operate this selection means, the user can switch between normal operation and rapid operation by operating the selection means according to the situation. It is possible to realize a toilet deodorizing device that is easy to use.
[0021]
In this embodiment, when the control circuit 26 receives a signal from the human body detection means 25 that detects the presence of a human body when the room temperature detected by the room temperature detection means 24 is below 20 ° C., for example, the self-heating decomposition catalyst 21 is received. Is energized. For example, in winter when the temperature of the toilet space is low, the wind blown from the outlet 16 is set to a warm air around 40 ° C. Conversely, in summer when the temperature rises, the energization of the self-heating decomposition catalyst 21 is stopped and only the blower 18 is operated. That is, apart from the activation of the adsorbent 20, the heater function provided in the self-heating decomposition catalyst 21 can be used for heating. Therefore, it is possible to heat the inside of the toilet with a simple configuration without providing a special heater for heating, and to realize an easy-to-use toilet deodorizing apparatus.
[0022]
In this embodiment, although not particularly illustrated, the air outlet 16 can be connected to the outside of the toilet. That is, this configuration can be realized by connecting, for example, a flexible duct to the outlet 16 and disposing the end of the duct outside the toilet. In this configuration, the adsorbed odor can be exhausted outside the toilet, so that it is not particularly necessary to provide a process for decomposing the odor component adsorbed by the adsorbent 20, and a downsized toilet deodorizing apparatus can be realized.
