Description

Automatic spraying device and vehicle air conditioning unit including the same {Auto spraying device and Vehicle Air Conditioning Unit containing the same}

The present invention relates to an automatic spraying device, and more specifically, to an automatic spraying device that applies wind from below to a solution (e.g., air freshener, antibacterial deodorant, etc.) sprayed in the form of fine particles from a nozzle so that it stays in the air for a long time, and an automatic spraying device equipped with the same. This relates to vehicle air conditioning systems.

Conventionally, various types of solution sprayers are known that spray a solution, such as an air freshener or an antibacterial deodorant, into the room at a set cycle in order to create a comfortable indoor atmosphere. This solution injection method can be broadly classified into four methods: gas injection spray method, solid room temperature volatilization method, liquid heat volatilization method, and liquid pressure spray method.

Among them, the gas injection method is a method in which the solution is placed in a steel or aluminum container along with the gas and the gas and solution are injected simultaneously using the high pressure of the gas. However, this method has a problem in that there is a risk of the container exploding if the temperature is over 50℃, and when spraying, the solution in the form of water droplets directly contacts the human body or interior decoration, causing discomfort or contaminating interior decoration.

The solid room temperature volatilization method is a method of volatilizing solidified or gelled flavorings in a container by contacting them with air at room temperature. Therefore, there is a problem in that the flavoring is consumed rapidly at high temperatures, while the liquid type heating method involves putting liquid flavorings in a container. It has a disadvantage in that it is difficult to control the direction and amount of scent emitted as it emits scent by applying heat to the wick that protrudes outside the container.

On the other hand, the liquid-type pressurized spray method is a method of pressurizing a container filled with a solution, such as a liquid perfume, with air, etc. to push the liquid perfume out of the container and spray it, so it is safer than the gas injection spray method and is a solid-type room temperature volatilization method. It is the most commonly adopted method because it not only consumes less fragrance than other methods, but also has the advantage of being easy to control the direction and amount of liquid fragrance sprayed.

However, the liquid-type pressurized spray method also has the problem of contaminating the surface of the decoration because the sprayed solution touches the interior decoration directly, and the sprayed liquid does not spread evenly and is concentrated only around the spray device, causing excessive fragrance and resistance to the spray. There is a problem that the farther away the device is, the less scent can reach it properly, making it unable to function properly.

In the description with reference to the accompanying drawings, identical components will be assigned the same drawing reference numerals, and overlapping descriptions thereof will be omitted. Also, in describing the present invention, if it is determined that a detailed description of related known technologies may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

1 is a conceptual diagram schematically showing the overall configuration of an automatic spraying device according to an embodiment of the present invention.

Referring to Figure 1, an automatic spraying device 1 according to an embodiment of the present invention includes a nozzle unit 10. The nozzle unit 10 has a first flow path 12 and a second flow path 14 formed therein. The first flow path 12 has a venturi 13 on the outlet side whose cross-sectional diameter is radially reduced compared to other parts, and the second flow path 14 is provided with the first flow path (13) inside the nozzle unit 10. 12) and may be connected at an angle.

Compressed air having a predetermined pressure is supplied from the air pump 20 to the first passage 12 of the nozzle unit 10. The air pump 20 is connected to the first flow path 12 of the nozzle unit 10 through a compressed air induction pipe 16 installed between the nozzle unit 10 and inside the nozzle unit 10. The second flow path 14, which is obliquely connected to the first flow path 12, is connected to the cartridge 40 through a liquid induction pipe 18.

As shown in the drawing, the cartridge 40 may be configured as a vessel with an open top and an accommodating space of a certain volume on the inside. A solution discharge pipe 44 to which the liquid induction pipe 18 is connected may be provided on one side of the lower edge of the cartridge 40. A replaceable solution capsule 30 is attached to the cartridge 40 in a detachable manner and supplies the solution to be sprayed into the space to be sprayed through the nozzle unit 10.

The solution capsule 30 may be configured to place a liquid solution in a container 31 and seal the opening (notation omitted) at the top of the container with a sealing sheet 32. Here, the solution contained in the container 31 may be, for example, an air freshener, an antibacterial deodorant, or a sterilizing disinfectant, but is not limited thereto, and the sealing sheet 32 is easily torn when hit with a sharp object with a pointed end or when pressure is applied. It may be thin rubber or aluminum packaging.

When the solution capsule 30 is coupled to the cartridge 40, at least a portion of the sealing sheet 32 is torn and opened to supply a solution to the cartridge 40. In order to open the sealing sheet 32, the inner bottom surface of the cartridge 40 has an end protruding at a predetermined height (the first height at which it can penetrate the sealing sheet 32 and enter the inside of the solution capsule 30). A rupture pin 42 is formed that is sharp and has a cross-sectional shape of a line (-) or a cross (+) when viewed from a plane.

By this configuration, the cartridge 40 is turned upside down as illustrated in the drawing (FIG. 1) so that the sealing sheet 32 of the solution capsule 30 faces the rupture pin 42. When force is applied in the direction of pressing the solution capsule 30 from above, the sealing sheet 32 is partially torn and opened by the rupture pin 42 formed on the bottom of the cartridge 40, and the inside of the solution capsule 30 is opened. The solution may flow into the cartridge 40.

The solution flowing into the cartridge 40 is sprayed into the target space through the inside of the nozzle unit 10 by the venturi effect caused by the compressed air of the air pump 20. More specifically, when compressed air is applied from the air pump 20 to the first flow path 12 communicating with the venturi 13 portion, a pressure drop occurs at the inlet of the second flow path 14, causing pressure inside the cartridge 40. The solution is sucked into the second flow path 14, passes through the venturi 13 together with compressed air, and is sprayed into the target space at a predetermined pressure.

A blower 50 is installed adjacent to the nozzle unit 10 and in the lower part of the nozzle unit 10. The blower 50 is operated with power applied from the outside under the control of the control unit 60 to generate wind. The wind generated by the blower 50 scatters the solution sprayed from the nozzle unit 10 into the air, and as a result, the solution falls on the floor of the target space or evaporates before reaching the surrounding walls, ceiling, or objects, causing the sprayed solution to Contamination of the surrounding area can be prevented.

In an embodiment of the present invention, the blower 50 is configured to apply wind from below at a predetermined wind speed and volume to the solution sprayed from the nozzle unit 10. As a result, the sprayed solution may scatter at a predetermined angle into the space above the nozzle unit 10. Preferably, the blower 50 may be arranged so that the outlet 51 of the blower 50 is inclined at an angle θ of at least 45 degrees and 80 degrees or less with respect to the outlet 11 of the nozzle unit 10. .

If the angle θ of the outlet 51 of the blower 50 with respect to the outlet 11 of the nozzle unit 10 is less than 45 degrees, the sprayed solution does not sufficiently scatter into the space above the nozzle unit 10. Therefore, the desired evaporation effect in the air is reduced, and if the angle θ of the outlet 51 of the blower 50 with respect to the outlet 11 of the nozzle unit 10 exceeds 80 degrees, the spray from the nozzle unit 10 This is because the scattering property decreases due to a rapid decrease in kinetic energy due to a sudden change in flow direction of the solution.

As mentioned earlier, the blower 50 mainly performs the role of scattering the spray solution into the air by applying wind from below at a predetermined wind speed and wind volume to the solution sprayed from the nozzle unit 10. In addition, the nozzle unit 10 ), it also serves to prevent the nozzle from clogging due to hardening of the solution remaining around the outlet 11 and causing malfunction of the device by removing the solution with wind so that it does not remain around the outlet 11.

The operation of the above-described air pump 20 and blower 50 is controlled by the control unit 60. The control unit 60 is based on detection information (humidity information) provided by a processor in which a program for applying operation commands to the air pump 20 and blower 50 at a preset time period is input, or by a humidity sensor 70, which will be described later. It may include a processor inputting a program that controls the strength of the wind generated by the blower 50 and the driving force of the air pump 20.

Reference numeral 70 indicates a humidity sensor that detects the humidity of the target space where the solution is to be sprayed from the nozzle unit 10. As such, the automatic spraying device 1 according to an embodiment of the present invention includes a humidity sensor 70 that detects the humidity of the target space where the solution is to be sprayed, such as the car interior, restroom, and duct of the car air conditioning system. The humidity sensor 70 may be electrically connected to provide detection information (humidity information) to the control unit 60.

The humidity sensor 70 senses a specific mechanism, such as using a change in electrical resistance or capacitance caused by absorption into a porous ceramic or polymer membrane, or using a change in the resonant frequency of the vibrator due to a change in the weight of the absorbent material installed on the vibrator. Without being limited to the method, any known humidity detection method sensor can be applied as a sensor for humidity detection.

As briefly mentioned above, the control unit 60 can control the blower 50 to adjust the wind strength based on the detection information of the humidity sensor 70. To this end, the control unit 60 determines a control value, such as a duty value, of the blower 50 based on the humidity information of the target space provided in real time by the humidity sensor 70, and controls the control value of the blower 50 with the determined control value. A program that controls operations may be stored.

The blower operation control program stored in the control unit 60 may be a program programmed to generate relatively stronger wind when humidity is high, and to relatively lower the wind strength when humidity is low. The higher the humidity of the target space, the lower the evaporation property of the sprayed solution, so in this case, the strength of the wind is increased to accelerate the evaporation rate of the solution.

The control unit 60 may also control the air pump 20 based on detection information from the humidity sensor 70 to adjust the spray pressure. To this end, the control unit 60 determines a control value, such as a duty value, of the air pump 20 based on the humidity information of the target space provided in real time by the humidity sensor 70, and controls the air pump 20 with the determined control value. ) A program that controls the operation may be stored.

The air pump operation control program stored in the control unit 60 relatively lowers the spray pressure (air pump driving force) as humidity increases, reduces the amount of solution sprayed, increases the spray time (air pump operation time), and lowers the spray pressure (air pump driving force) when humidity is low. It may be a program programmed to relatively increase the spray pressure to increase the amount of solution sprayed, but conversely reduce the spray time (air pump operation time).

This means that the higher the humidity of the target space, the lower the vaporization property of the sprayed solution, and conversely, the lower the humidity, the higher the vaporization property is, so the amount and time of the sprayed solution are adjusted according to the humidity.

FIG. 2 is an assembled cross-sectional view showing a preferred embodiment of the automatic spraying device shown in FIG. 1.

As shown in Figure 2, the automatic spraying device 1 according to an embodiment of the present invention includes the above-described nozzle unit 10, air pump 20, cartridge 40, blower 50, and humidity sensor 70. , not shown in FIG. 2) can be simultaneously mounted in the mounting space inside the case 80 to form a single module (single product) with a compact size or configuration. At this time, the arrangement of the components inside the mounting space is preferably as shown in the drawing, but is not limited to this.

The case 80 preferably has a hexahedral configuration with a roughly square cross-sectional shape when viewed from the side, as shown in the example of FIG. 2, but the case 80 is not limited thereto, and a lid 85 may be provided on one side of the upper surface. The lid 85 is used to open and close a part of the case 80 where the cartridge 40 is installed in order to replace the solution capsule 30, and is available in various forms such as the upward opening type as shown, a slide type, and a detachable type. It can be configured.

In FIG. 2, the unillustrated reference numeral 90 is a control panel through which user input is used to operate the device. The control panel includes an on/off switch for turning the power on/off and other features so that the user can easily identify the switch on/off status with the naked eye. It may include a light source that emits colored light, such as an LED, a board on which the on/off switch and light source are mounted, and a display for displaying information.

Figure 3 is a view of the blower outlet portion shown in Figure 2. Figure 3 (a) is an enlarged view of the main part of the present invention showing the blower outlet of Figure 2, and Figure 3 (b) is an enlarged view of the main part of the present invention ( This is a conceptual diagram of the blower outlet part shown in a).

As shown in FIG. 3, the outlet 51 of the blower 50 has an upper output end ( 510) and a nozzle plate 530 disposed adjacent to the lower part of the upper output end 510 so that an elongated slit-shaped nozzle portion 520 is formed between the upper output end 510. .

At this time, the vertical position of the tip portion 531 formed on the nozzle plate 530 is formed at a position approximately corresponding to the end of the straight portion 512 of the upper output end 510 based on the gas flow direction, so that the nozzle portion ( When air is discharged in a direction in contact with the lower surface of the upper output end 510 through 520, the discharged air may flow along the curved portion 514 to generate a Coanda jet.

In Figure 3(b), reference numeral 518 indicates a notch formed in the upper output terminal 510. The notch 518 is formed at a point spaced a predetermined distance away from the curved portion 514 on another straight portion 516 starting from the end of the curved portion 514 based on the fluid flow direction, thereby forming the nozzle plate 530. It serves to separate the air flowing along the lower surface from the lower surface, that is, it functions as a flow separation.

Figure 4 is an installation illustration showing a preferred installation state of the automatic spraying device according to the above-described embodiment of the present invention, and is a diagram schematically showing the application to the air conditioning duct of a vehicle air conditioning system.

As shown in Figure 4 (a), the automatic spray device 1 according to an embodiment of the present invention is an example, and can be detachably coupled to the air conditioning duct 2 constituting a vehicle air conditioning system. Preferably, it is disposed at a distance in front of the air conditioner filter (3), so that the solution passes through the air conditioner filter (3) together with the fluid air in a evaporated state before passing through the air conditioner filter (3), and the solution component is deposited on the inner wall of the duct. It can be configured to absorb and apply evenly.

As another example, as shown in (b) of FIG. 4, the automatic spray device 1 may be configured to be used by simply mounting it in front of the intake port 52 among the intake parts including the intake door 5. In this case, the driver can use the automatic spray device 1 according to an embodiment of the present invention by switching on the air conditioning mode to the ventilation mode.

Of course, although not shown, it can be applied to ducts of building air conditioning equipment, and can also be applied to home and office air purifiers, so it is clear that such application forms can also be included in the scope of the present invention.

In FIG. 4, the unexplained reference numeral 4 denotes a blower of an air conditioning unit.

Among the spraying methods used in conventional solution sprayers that spray solutions, such as air fresheners or antibacterial deodorants, into the room at a set cycle to make the indoor atmosphere comfortable, the most commonly adopted liquid type pressurized spraying method (pressurizing the container with air, etc. The method of pushing the solution filled in and spraying it outward has higher safety compared to other methods.

However, if the solution sprayed in the target space touches the interior decoration directly, there is a problem of contaminating the surface of the decoration, and the spray solution is not spread evenly and is concentrated only around the spray device, causing a feeling of rejection. There is a problem that the further away the solution is, the less it can reach and it cannot function properly.

On the other hand, according to the automatic spraying device according to an embodiment of the present invention, the blower is configured to apply wind from below to the solution sprayed in the form of fine particles from the nozzle unit, so that the sprayed solution is not concentrated locally around the device but is spread in the target space. It can spread evenly throughout the entire area, achieving the desired effect (fragrance, antibacterial, deodorization, disinfection, etc.).

In addition, in the automatic spraying device according to an embodiment of the present invention, a blower applies wind from below to the solution sprayed in the form of fine particles from the nozzle unit and causes it to stay in the air for a long time, causing solution droplets in the form of fine particles to fall on the floor or to the surrounding walls, It can evaporate before reaching the ceiling or objects, thereby preventing solution droplets from forming on the surfaces of surrounding walls, ceilings, objects, etc., causing contamination.
