Description

  The present invention relates to an aroma component deodorizing apparatus that deodorizes an aroma component.

  In order to keep the environment in the passenger compartment favorable, a supply device for supplying an aromatic component from the air outlet of an air conditioner has been proposed. However, if the fragrance component is supplied from the air outlet, the fragrance component is filled in the passenger compartment, so a large amount of the fragrance component is required, and an in-vehicle environment according to each passenger's preference is provided. It was difficult.

Therefore, a supply device including an air cannon for firing a vortex ring containing an aromatic component toward an occupant has been proposed. Thereby, since an aroma component can be supplied locally, it becomes possible to provide the vehicle interior according to each passenger | crew's preference using a small amount of aroma component. There has also been proposed a supply device that switches and supplies a plurality of aroma components (see, for example, Patent Document 1 or 2).

  By the way, when trying to switch and supply a plurality of fragrance components, different fragrance components are mixed in the chamber of the air cannon, etc., so that there is a problem that the occupant feels uncomfortable depending on the type of the fragrance component. Therefore, in the supply device described in Patent Document 2, titanium oxide, which is a photocatalyst, is applied in the chamber of the air cannon, and an ultraviolet lamp is attached in the chamber to eliminate the aromatic component remaining in the device. I try to smell.

  However, even if the fragrance component is deodorized using a photocatalyst, the air cannon is formed with a discharge port for releasing the vortex ring, so that the fragrance component flows into the vehicle interior via this discharge port. There is a risk that. Thus, simply deodorizing the air in the air cannon may cause the fragrance component to flow out of the air cannon, making it difficult to sufficiently deodorize the fragrance component remaining in the device. It was.

  The objective of this invention is providing the fragrance component deodorizing apparatus which can deodorize the fragrance component which remains effectively.

Fragrance deodorizing device of the present invention, a firing means for Ru comprising a discharge port for air vortex containing aromatic components are fired, is connected to the firing means, to suck air into the firing means from the outlet It has a suction means and a deodorizing means connected to the launching means for guiding the air sucked into the launching means.

The control unit 22 includes a microprocessor (CPU) (not shown), and a ROM, a RAM, and an I / O port are connected to the CPU via a bus line. The ROM stores control programs and various map data, and the RAM temporarily stores data calculated by the CPU. Furthermore, the control unit 22 is connected to a switch 26 operated to set the type of fragrance component, the launch modes of the vortex rings V1 and V2, and an in-vehicle camera (not shown) that detects the nose position of the passengers D and P. Has been. The control unit 22 calculates various control signals based on the operation signal of the switch 26, and controls the type of fragrance component, the firing mode of the vortex rings V1 and V2, and the like.

  Then, the deodorizing function of the fragrance component deodorizing apparatus incorporated in the supply apparatus 10 is demonstrated. As described above, since a plurality of fragrance components are switched according to the occupant's switch operation or the like, in order to avoid mixing of the fragrance component before switching and the fragrance component after switching, the air supply gun 12 is provided in the supply device 10. , 13 and the fragrance supply unit 20 are incorporated. First, as shown in FIG. 4, each fragrance supply unit 20 is connected to a blower fan 31 as a suction means via a pipe 30. The blower fan 31 is connected to the fragrance supply unit 20 via a pipe 32 as a deodorizing means. The ozone generating part (ozone generating means) 33 is connected. In addition, in order to supply a driving current to the blower fan 31, the supply device 10 is provided with a fan driving circuit 34 that controls the driving current.

The high voltage generation circuit 35 is controlled by the control unit 22. It is controlled based on the signal.

Here, FIGS. 5A and 5B are explanatory views showing the operating state of the supply device 10, and FIG. 5A shows a fragrance supply mode for supplying fragrance components to the air cannons 12 and 13. , (B) shows a device deodorization mode for deodorizing fragrance components remaining in the air cannons 12 and 13 and the fragrance supply unit 20. First, as shown in FIGS. 5A and 5B, the fragrance supply unit 20 is constituted by a rotating plate 40 provided between a pipe 21 and a pipe 30. The rotating plate 40 is provided with a porous body 40 a impregnated with the fragrance component A and a porous body 40 b impregnated with the fragrance component B, and a through-hole 40 c communicating the pipe 21 and the pipe 30. Is formed. By rotating the rotating plate 40 at a predetermined angle in accordance with the occupant's switch operation or the like, the fragrance supply unit 20 is in a first fragrance supply position where the porous body 40a is opposed to the pipe 21, and the pipe 21 Thus, the second fragrance supply position where the porous body 40b is opposed and the device deodorization position where the through hole 40c is opposed to the pipes 21 and 30 are switched. The ozone generator 33 is composed of a needle-like discharge electrode 33a and an annular counter electrode 33b, and a high voltage is applied to the discharge electrode 33a and the counter electrode 33b so as to be near the tip of the discharge electrode 33a. By generating silent discharge, ozone (O ₃ ) having a deodorizing effect can be generated.

  In the first fragrance supply mode in which the fragrance component A is supplied to the air cannons 12 and 13, as shown in FIG. 5 (A), the rotating plate 40 of the fragrance supply section 20 is operated to the first fragrance supply position. The porous body 40a impregnated with the predetermined fragrance component A is opposed to the pipe 21. Thereby, the fragrance component A diffusing from the porous body 40a is supplied to the barrel portions 12d and 13d of the air cannons 12 and 13 through the pipe 21. Under this condition, the vortex rings V1 and V2 containing the predetermined fragrance component A are fired from the air cannons 12 and 13 by driving the pump drive units 12b and 13b of the air cannons 12 and 13. . Similarly, in the second fragrance supply mode for supplying the fragrance component B to the air cannons 12 and 13, the rotating plate 40 of the fragrance supply section 20 is operated to the second fragrance supply position, and the predetermined fragrance component B is The impregnated porous body 40b is opposed to the pipe 21.

  After the vortex rings V1 and V2 are fired, the supply device 10 executes a device deodorization mode in which the aroma components remaining in the air cannons 12 and 13 and the pipe 21 are deodorized. As shown in FIG. 5B, when the device deodorizing mode is executed, the rotating plate 40 is rotated to the device deodorizing position where the through holes 40c are opposed to the pipes 21 and 30, and ozone is generated. A high voltage is applied to the discharge electrode 33a and the counter electrode 33b of the portion 33. Next, the blower fan 31 is driven so as to suck air from the discharge ports 12c and 13c of the air cannons 12 and 13, and the air taken in from the discharge ports 12c and 13c of the air guns 12 and 13 is supplied to the pipe 21 and the fragrance supply. The ozone generation unit 33 is guided through the unit 20, the piping 30, the blower fan 31, and the piping 32. And ozone is supplied with respect to the air which flowed into the ozone generation part 33, and after the aromatic component in air is deodorized, it will be discharged | emitted from the blower outlet 42 via the piping 41. FIG. The device deodorization mode is executed over a predetermined time until the fragrance components remaining in the air cannons 12 and 13, the pipe 21, and the fragrance supply unit 20 are deodorized.

  Then, the execution procedure of the fragrance supply mode and apparatus deodorization mode mentioned above is demonstrated along a flowchart. Here, FIG. 6 is a flowchart showing an execution procedure of the fragrance supply mode and the device deodorization mode. As shown in FIG. 6, in step S1, the fragrance supply unit 20 is switched to the first or second fragrance supply position in accordance with a switch operation or the like. In the subsequent step S2, it is determined whether or not the firing conditions of the vortex rings V1 and V2 are met. If the firing conditions are met, the process proceeds to step S3, and the air cannons 12 and 13 contain a predetermined fragrance component. Vortex rings V1 and V2 are fired. When the vortex rings V1 and V2 are fired, the fragrance supply unit 20 is switched to the device deodorization position in step S4, ozone is generated by the ozone generation unit 33 in step S5, and the blower fan 31 is driven in step S6. The Next, in step S7, it is determined whether or not a predetermined time has elapsed since the execution of the device deodorization mode. If the predetermined time has not elapsed, the flow returns to step S5 to continue the device deodorization mode. . On the other hand, if it is determined in step S7 that the predetermined time has elapsed, generation of ozone by the ozone generator 33 is stopped in step S8, and driving of the blower fan 31 is stopped in step S9. .

  In this way, ozone is not supplied toward the air cannons 12 and 13, but air is sucked from the air cannons 12 and 13 toward the ozone generator 33 and ozone is supplied to the sucked air. Since it did in this way, it becomes possible to deodorize, without making an aromatic component flow out from the discharge ports 12c and 13c of the air cannons 12 and 13. In addition, since the air is guided from the air cannons 12 and 13 to the ozone generating unit 33 via the fragrance supply unit 20, not only the inside of the air cannons 12 and 13 is deodorized but also the fragrance supply unit 20 is efficiently turned off. It becomes possible to smell. Thereby, even if it is a case where a fragrance component is switched and used, it becomes possible to switch without mixing a fragrance component.

  In addition, the device deodorization mode described above not only deodorizes the fragrance components remaining in the air cannons 12, 13 and the like, but also sets the ozone concentration and the amount of air blown to properly deodorize and disinfect the vehicle interior. It can also be used as a deodorizing mode. This in-vehicle deodorization mode is executed under the condition that there is an occupant in the vehicle interior, and is executed under the low output mode for supplying low-concentration ozone into the vehicle interior and the state in which there is no occupant in the vehicle interior. A high output mode for supplying high-concentration ozone into the passenger compartment is set.

  When the low output mode is set by an occupant's switch operation or the like, low-concentration ozone is supplied into the passenger compartment for a predetermined time, and sterilization and deodorization in the passenger compartment are executed. The ozone concentration in the low output mode is desirably set to a concentration that does not affect the human body (for example, 0.06 ppm or less). In addition, when the high output mode is set by an occupant's switch operation, etc., it is determined that there is no occupant in the passenger compartment by an in-vehicle camera, an infrared sensor, etc. It is supplied to perform sterilization and deodorization in the passenger compartment. The ozone concentration in the high output mode is desirably set to a concentration (for example, 0.06 ppm or more and 0.10 ppm or less) that can provide a sufficient deodorizing effect and sterilizing effect. In this way, not only deodorizing the fragrance component remaining in the supply device 10 by the device deodorization mode, but also by performing deodorization and sterilization in the vehicle interior by the vehicle deodorization mode, Can be used effectively, and the vehicle quality can be improved.

  Furthermore, when ozone is released into the passenger compartment, ozone is released from the outlet 42 of the supply device 10, but the present invention is not limited to this, and the ozone generator 33 is not shown. You may make it supply ozone with respect to a ventilation duct by connecting with respect to a ventilation duct. Thereby, not only the vehicle interior but also the inside of the air conditioner can be deodorized and sterilized, and a good vehicle environment can be provided.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the illustrated case, the blower fan 31 is disposed upstream of the ozone generator 33, but the present invention is not limited to this, and the blower fan 31 is disposed downstream of the ozone generator 33. May be. In addition, although the blower fan 31 is provided as a suction means for guiding the air sucked from the air cannons 12 and 13 to the ozone generator 33, the suction means is not limited to a blower provided with a propeller or an impeller. An air blower that rotates the rotor and pumps air may be employed.

  Moreover, although the ozone generation part 33 is provided as a deodorizing means, it is not restricted to this, You may make it use an activated carbon filter, a photocatalyst, etc. as a deodorizing means. Further, in the illustrated case, the pipe 21 is connected to the barrel portions 12d and 13d of the air cannons 12 and 13, but the pipe 21 may be connected to the pump bodies 12a and 13a of the air cannons 12 and 13. It goes without saying that it is good. Furthermore, although two types of fragrance components are switched and used, three or more types of fragrance components may be switched or one type of fragrance component may be used. Furthermore, although a pair of air cannons 12 and 13 are provided as the launching means, three or more air cannons may be provided, or one air cannon may be provided.

  Further, in the illustrated case, the electric motor is driven to project the rod members 12e and 13e so that the vortex rings V1 and V2 are fired from the air cannons 12 and 13, but this is limited to this structure. Instead, by incorporating an electromagnetic coil and a movable iron core into the air cannons 12 and 13, the vortex rings V1 and V2 may be fired from the air cannons 12 and 13 using electromagnetic force. Furthermore, although the air cannons 12 and 13 are provided with bellows-shaped pump bodies 12a and 13a, air may be pushed out using a diaphragm. Although the annular vortex rings V1 and V2 are fired from the air cannons 12 and 13, the shape of the air vortex is not limited to the annular shape, and it is possible to fly a predetermined distance with a unified shape. Any shape air vortex may be used.
