  The present invention relates to a deodorizing system and a deodorizing method for a toilet room.

Conventionally, in order to deodorize the toilet room, for example, the smell of the toilet room is detected by an odor sensor installed in the toilet room, and the detection signal is stored in the information controller through transmission / reception means as information on the toilet equipment environment, and deodorized A toilet apparatus that appropriately operates means (deodorizer) and ventilation means (ventilation fan) has been proposed (see Patent Document 1).
JP 2002-89908 A

  However, for example, when the temperature of a toilet room is adjusted by cooling or heating, the temperature-adjusted air comes out by the operation of the ventilation fan. On the other hand, if only the deodorizer is operated, if the odor level is high, it takes time to deodorize to the extent that no odor is felt, and the toilet room is used comfortably. There is a problem that it is difficult.

  An object of the present invention is to provide a deodorizing system and a deodorizing method for a toilet room that can be used comfortably by appropriately operating a deodorizer and a ventilation fan according to the odor level in the toilet room.

  In order to solve the above-mentioned problems, claim 1 of the present invention provides a deodorizer for deodorizing a toilet room, a ventilation fan for ventilating the toilet room, and a control signal to the deodorizer and the ventilation fan. A deodorizing system for a toilet room provided with a control device capable of transmitting, wherein the control device determines whether or not an odor level in the toilet room is higher than a first set odor level. When the unit determines that the odor level is higher than the first set odor level, the operation start signal is transmitted to the deodorizer based on the determination, and the operation start signal is transmitted to the deodorizer. From the second set odor level by the second odor level determination unit for determining whether the odor level in the toilet room after transmission is higher than the second set odor level that is higher than the first set odor level. High In the case where the determination that, based on the determination, to provide a deodorizing system toilet room and transmits an operation start signal to the ventilation fan.

  The control device determines whether or not the odor level in the toilet room after the operation start signal is transmitted to the ventilation fan is maintained higher than the second set odor level. When the high odor level maintenance determination unit determines that a state higher than the second set odor level is not maintained, it is preferable to transmit an operation stop signal to the ventilation fan based on the determination.

  According to a third aspect of the present invention, in order to solve the above problem, a deodorizer for deodorizing the toilet room, a ventilation fan for ventilating the toilet room, and a control signal to the deodorizer and the ventilation fan are provided. A deodorizing method for a toilet room that deodorizes a toilet room using a controllable control device, wherein the control device determines whether the odor level in the toilet room is higher than a first set odor level. When the determination is made that the odor level is higher than the first set odor level, based on the determination, the deodorizer transmits an operation start signal, and the deodorizer outputs an operation start signal. It is determined whether the odor level in the toilet room after transmission is higher than the second set odor level that is higher than the first set odor level, and is determined to be higher than the second set odor level. If the There are, provides a deodorizing method toilet room, characterized in that to transmit the operation start signal to the ventilation fan.

  According to claim 1 and claim 3, for example, an odor level at which odor in the toilet room is felt is set in advance to the first set odor level, and the odor in the toilet room is higher than the first set odor level. In this case, since the control device first transmits an operation start signal to the deodorizer, it is not necessary to operate the ventilation fan, and the control device can be made economical. Further, for example, when the temperature of the toilet room is adjusted by cooling or heating, the temperature-adjusted air can be prevented from going out due to the operation of the ventilation fan.

  On the other hand, for example, after the deodorizer is activated, when the odor level in the toilet room is further increased to be higher than the second set odor level, which is higher than the first set odor level, the control device switches to the ventilation fan. By transmitting the operation start signal, the ventilation fan is operated in addition to the operation of the deodorizer. Therefore, the odor level in the toilet room can be lowered in a short time.

  According to claim 2, when the control device determines that the odor level in the toilet room after transmitting the operation start signal to the ventilation fan is not maintained higher than the second set odor level, The operation of the ventilation fan is stopped by transmitting an operation stop signal. Therefore, for example, when the odor level in the toilet room is lower than the first set odor level but lower than the second set odor level, deodorization can be performed only by operating the deodorizer. In addition to being economical, it is possible to suppress as much as possible that the air whose temperature has been adjusted by cooling or heating the toilet room is exposed to the outside due to the operation of the ventilation fan.

  When the odor level in the toilet room is not higher than the set odor level A (odor level ≦ set odor level A, hereinafter the same in the high odor level maintenance determination unit 33), the second odor level determination unit 32 It is determined that the odor level is not higher than the set odor level A.

  On the other hand, when the odor level in the toilet room is higher than the set odor level A (odor level> set odor level A, hereinafter the same in the high odor level maintenance determination unit 33), the second odor level determination unit 32 has an odor level. It is determined that the odor level is higher than the set odor level A.

  When it is determined that the odor level is higher than the set odor level A, the control device 3 generates an operation start signal for the ventilation fan based on the determination.

  The high odor level maintenance determination unit 33 determines whether or not the odor level in the toilet room 9 after transmitting the operation start signal of the ventilation fan is still maintaining a high odor level higher than the set odor level A. Specifically, whether or not the odor level in the toilet room is higher than the set odor level A is determined based on the detection data from the odor sensor 4.

  When the odor level in the toilet room is still higher than the set odor level A, the high odor level maintenance determination unit 33 performs a maintenance determination that the odor level is still maintained higher than the set odor level A. . On the other hand, when the odor level in the toilet room is not higher than the set odor level A, it is determined that the odor level is not maintained higher than the set odor level A.

  Moreover, when the determination that the high odor level maintenance determination unit 33 does not maintain the determination is made, the control device 3 generates an operation stop signal for the ventilation fan based on the determination.

  The low odor level maintenance determination unit 34 is not maintained by the second odor level determination unit 32 after the determination that the odor level is not higher than the set odor level A or by the high odor level maintenance determination unit 33. Whether or not the odor level in the toilet room after the determination is maintained is higher than the set odor level B is determined based on the detection data from the odor sensor 4.

  When the odor level in the toilet room is higher than the set odor level B, the low odor level maintenance determination unit 34 performs a maintenance determination that the odor level is maintained higher than the set odor level B. On the other hand, when the odor level in the toilet room is not higher than the set odor level B, it is determined that the above state is not maintained.

  In addition, when the low odor level maintenance determination unit 34 determines that the above is not maintained, the control device 3 generates a deodorizer operation stop signal based on the determination.
