Description

[Technical Field]

[0001] The present invention relates to a mist spraying device that sprays mist onto passengers in a vehicle interior. [Background technology]

[0002] A known mist sprayer of this type is disclosed in, for example, Patent Document 1. This type of mist sprayer humidifies the vehicle interior by spraying moisture directly onto the exposed skin of passengers. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-168745 Summary of the Invention [Problem to be solved by the invention]

[0004] Sunlight penetrates into the interior of a vehicle through the windshield and window glass. This causes sunburn on exposed areas of the skin of passengers inside the vehicle. However, while the mist sprayer described above humidifies the exposed areas of the passenger's skin by spraying moisture onto them, it does not address sunburn on the exposed areas of the passenger's skin. Therefore, there is a demand for a mist sprayer that can address sunburn on exposed areas such as the passenger's skin. [Means for solving the problem]

[0005] Various aspects of the mist spraying device for solving the above problems will be described below. [Aspect 1] A mist spraying device mounted on a vehicle, comprising: a spraying unit that sprays skin care mist onto exposed areas of an occupant inside the vehicle cabin; an information acquisition unit that acquires behavioral history information of the occupant; an estimation unit that estimates the degree of sunburn on the exposed areas based on the behavioral history information acquired by the information acquisition unit; and a spray control unit that controls the spraying of the mist from the spraying unit based on the degree of sunburn estimated by the estimation unit.

[0006] According to the above configuration, the mist is sprayed from the spraying portion onto the occupant's exposed parts based on the degree of sunburn on those parts, so that the sunburned exposed parts can be appropriately cared for with the mist. Therefore, sunburn on the occupant's exposed parts can be appropriately dealt with.

[0007] [Aspect 2] The mist spraying device according to [Aspect 1], wherein the spraying unit is configured to be able to spray a plurality of different types of mists.

[0008] According to the above configuration, for example, by spraying two different types of mist, a moisturizing mist and a cooling mist, onto sunburned exposed areas from the spraying unit, it is possible to both moisturize and cool the sunburned exposed areas, thereby providing better care for the sunburned exposed areas. [Effects of the Invention]

[0009] The present invention can address sunburn on exposed parts of the occupant. [Brief explanation of the drawings]

[0010] [Figure 1] 1 is a schematic diagram illustrating a mist spraying device mounted on a vehicle in one embodiment. [Figure 2] 10 is a flowchart showing a mist spray processing routine. DETAILED DESCRIPTION OF THE INVENTION

[0011] An embodiment will be described below with reference to the drawings. <Vehicle 11> As shown in Fig. 1, a front seat 14 on which a driver 13, as an example of a passenger, is seated is disposed in a passenger compartment 12 of a vehicle 11 such as an automobile. An instrument panel 15 is disposed in front of the front seat 14 in the passenger compartment 12. A car navigation device 16 and a steering wheel 17 are provided on the instrument panel 15. A windshield 18 is provided above the instrument panel 15 of the vehicle 11. A mist spraying device 19 is mounted on the vehicle 11.

[0012] <Mist sprayer 19> 1, the mist spraying device 19 includes a camera 20, a spraying unit 21, and a control device 22. The control device 22 is electrically connected to the camera 20 and the spraying unit 21. The camera 20 captures an image of the driver 13 seated in the front seat 14 in the vehicle interior 12. The control device 22 determines, for example, based on the image captured by the camera 20, whether or not the driver 13 is seated in the front seat 14.

[0013] <Injection part 21> As shown in FIG. 1, the sprayer 21 is provided, for example, on a ceiling portion above the front seat 14 in the vehicle interior 12. The sprayer 21 sprays a skin care mist M onto exposed parts 23 of the driver 13 seated in the front seat 14. In this example, the exposed parts 23 are, for example, the face and hair of the driver 13. The mist M is made of fine liquid particles. The particle diameter of the mist M is, for example, about several μm to 100 μm.

[0014] The spray unit 21 is configured to be able to spray a plurality of different types of mists M. That is, as an example, the spray unit 21 is configured to be able to spray two types of mists M with different effects, namely, a moisturizing mist and a cooling mist. The spray unit 21 is configured so that cartridges (not shown) containing the moisturizing mist and the cooling mist, respectively, can be detachably attached thereto.

[0015] The moisturizing mist is composed of mist M containing moisturizing ingredients. The cooling mist is composed of, for example, water mist M. The cooling mist cools the driver 13 by utilizing the heat of vaporization when the water mist M sprayed onto the exposed part 23 of the driver 13 evaporates on the surface of the exposed part 23. The spraying unit 21 is configured to be able to selectively spray the moisturizing mist or the cooling mist onto the exposed part 23 of the driver 13 from a nozzle (not shown).

[0016] That is, the sprayer 21 is capable of spraying either the moisturizing mist or the cooling mist, and is also capable of spraying both the moisturizing mist and the cooling mist simultaneously.

[0017] <Control device 22> As shown in Fig. 1, the control device 22 is configured by a computer having a CPU, ROM, and RAM. The ROM stores a mist spray program shown in the flowchart of Fig. 2, various setting data, a threshold value R (described later), and the like. The control device 22 implements an information acquisition unit 24, an estimation unit 25, and a spray control unit 26 by executing the mist spray program stored in the ROM.

[0018] The information acquisition unit 24 acquires, via wireless communication, movement history information of the vehicle 11 from the car navigation device 16, and acquires behavior history information of the driver 13 from a mobile terminal 27 such as a smartphone carried by the driver 13. An application for acquiring the behavior history information of the driver 13 is installed in advance in the mobile terminal 27. The information acquisition unit 24 acquires the behavior history information from the mobile terminal 27 through the application.

[0019] The estimation unit 25 estimates the degree of sunburn of the exposed parts 23 of the driver 13 based on the behavior history information acquired by the information acquisition unit 24. That is, the estimation unit 25 calculates the degree of sunburn as a numerical estimate based on parameters necessary for estimating the degree of sunburn that are set in advance in the behavior history information. Examples of the parameters necessary for estimating the degree of sunburn include the location of the driver 13, the date and time of the activity at the location, the weather, the temperature, the humidity, and the UV index.

[0020] For example, the estimation unit 25 scores each of the parameters based on the behavior history information and adds them up to calculate an estimated value that quantifies the degree of sunburn. The spray control unit 26 controls the spraying of the mist M from the spraying unit 21 based on the estimated value that quantifies the degree of sunburn estimated by the estimation unit 25.

[0021] <Mist spray processing routine> Next, the mist spray processing routine executed by the control device 22 will be described with reference to the flowchart shown in Fig. 2. The mist spray processing routine is executed when the driver 13 is seated in the front seat 14 inside the vehicle interior 12, and is thereafter repeatedly executed at predetermined time intervals.

[0022] When the mist spray processing routine is executed, first, the control device 22 acquires behavior history information of the driver 13 (step S1). Next, the control device 22 calculates a quantified estimated value of the degree of sunburn of the exposed part 23 of the driver 13 based on the behavior history information of the driver 13 acquired in step S1 (step S2). Next, the control device 22 determines whether the estimated value calculated in step S2 is equal to or greater than a threshold value R stored in the ROM (step S3).

[0023] This threshold value R is set to the minimum value at which it is estimated that the exposed portion 23 is sunburned to the extent that care against sunburn is required. If the determination result in step S3 is negative, the control device 22 ends the mist spraying process routine. If the determination result in step S3 is positive, the control device 22 causes the spraying unit 21 to spray mist M (step S4). Thereafter, the control device 22 ends the mist spraying process routine.

[0024] <Operation of the embodiment> The driver 13, carrying the mobile terminal 27, gets into the vehicle 11 and sits in the front seat 14 in the passenger compartment 12. When the exposed area 23 of the driver 13 is sunburned to the extent that care is required for the sunburn, the spraying unit 21 sprays moisturizing mist and cooling mist onto the exposed area 23. This moisturizes and cools the sunburned exposed area 23, thereby providing appropriate care for the sunburned exposed area 23.

[0025] <Effects of the embodiment> According to the embodiment described above in detail, the following effects are achieved. (1) The mist spraying device 19 is mounted on the vehicle 11 and includes an spraying unit 21 that sprays skin care mist M onto exposed areas 23 of the driver 13 inside the vehicle cabin 12, an information acquisition unit 24 that acquires behavioral history information of the driver 13, an estimation unit 25 that estimates the degree of sunburn on the exposed areas 23 based on the behavioral history information acquired by the information acquisition unit 24, and an injection control unit 26 that controls the spraying of the mist M from the spraying unit 21 based on the degree of sunburn estimated by the estimation unit 25.

[0026] According to the above configuration, the mist M is sprayed from the spraying unit 21 onto the exposed part 23 of the driver 13 based on the degree of sunburn on the exposed part 23, thereby making it possible to appropriately care for the sunburned exposed part 23. Therefore, sunburn on the exposed part 23 of the driver 13 can be appropriately addressed.

[0027] (2) In the mist spraying device 19, the spraying unit 21 is configured to be able to spray two different types of mist M, namely, moisturizing mist and cooling mist. According to the above configuration, by spraying two different types of mists M, a moisturizing mist and a cooling mist, from the sprayer 21 onto the sunburned exposed area 23, it is possible to both moisturize and cool the sunburned exposed area 23. Therefore, better care can be provided for the sunburned exposed area 23.

[0028] <Example of change> The above embodiment can be modified as follows: Furthermore, the above embodiment and the following modifications can be combined with each other within the scope of technical compatibility.

[0029] The spraying unit 21 may be configured to be capable of spraying only one type of mist M. The sprayer 21 may be configured to spray three or more types of mist M. In this case, the three or more types of mist M may include a sunscreen mist containing a sunscreen component. Furthermore, in this case, the type of mist M sprayed from the sprayer 21 onto the exposed portion 23 of the driver 13 may be changed depending on the degree of sunburn on the exposed portion 23. For example, if the exposed portion 23 is barely sunburned, the sprayer 21 may spray a sunscreen mist onto the exposed portion 23. For example, if the exposed portion 23 is only slightly sunburned, the sprayer 21 may spray only a moisturizing mist onto the exposed portion 23. For example, if the exposed portion 23 is only slightly sunburned, the sprayer 21 may spray both a moisturizing mist and a cooling mist onto the exposed portion 23. In this case, the moisturizing mist and the cooling mist may be sprayed simultaneously, or one at a time.

[0030] The amount of mist M sprayed from the spraying unit 21 onto the exposed portion 23 of the driver 13 may be changed depending on the degree of sunburn on the exposed portion 23. For example, the amount of mist M sprayed from the spraying unit 21 onto the exposed portion 23 may increase as the degree of sunburn on the exposed portion 23 increases from light to heavy.

[0031] The estimation unit 25 may estimate the degree of sunburn of the exposed part 23 based on an image of the exposed part 23 of the driver 13 captured by the camera 20 in addition to the behavior history information acquired by the information acquisition unit 24.

[0032] The exposed portion 23 may be an arm or a leg of the driver 13. In this case, the ejection portion 21 is disposed in accordance with the position of the exposed portion 23. The mobile terminal 27 may be a smart watch, a smart band, or the like.

[0033] The occupant may be a person other than the driver 13. [Explanation of symbols]
