Description

Active substance supply device and active substance supply system including the same

[0001] The present invention relates to an effective substance supply device and an effective substance supply system including the same, and more specifically, to an effective substance supply device for supplying an effective substance indoors in conjunction with a ventilation device and an effective substance supply system including the same.

[0002]

[0003] Phytoncides are natural antimicrobial substances secreted by trees that are known to be effective in purifying the air and removing harmful particles such as fine dust. Forest bathing is a good way to experience these phytoncides firsthand, but caution is required as there is a possibility of exposure to ozone or allergy-causing substances depending on the season or terrain.

[0004] For this reason, attempts are being made to utilize phytoncides in indoor environments to recreate the pleasant sensation of resting in a forest.

[0005] Conventionally, phytoncides were directly inserted into the ventilation device, or the phytoncide supply device was designed as an integrated unit with the ventilation device.

[0006] Consequently, there was a problem where air quality was not improved uniformly because phytoncides could accumulate excessively at specific points.

[0007] In addition, when a phytoncide supply device is installed inside the device, there were problems such as structural constraints that degraded the device's performance or increased its volume. Furthermore, it was difficult for users to replace or replenish the phytoncide whenever it was depleted, causing significant inconvenience during actual operation.

[0008] Maintaining the concentration of phytoncides is also an issue that cannot be overlooked. Previously, phytoncide solutions with very low concentrations were primarily used; these concentrations were so low that they were difficult to even verify with standard measuring equipment, and the perceived effects were not sufficient.

[0009] As a result, methods such as mixing essential oils into phytoncide water or applying superabsorbent materials to allow for slow release have been studied, but commercialization is difficult due to additional issues such as maintaining airtightness and compatibility with air conditioning equipment when actually applied.

[0010] Nevertheless, attempts to create more pleasant indoor air by combining ventilation systems with phytoncides continue. This is highly attractive because it allows one to experience the fresh air quality of a forest indoors, while avoiding the risks of ozone or allergens that can occur during outdoor activities.

[0011] However, technical implementation is required to maintain phytoncides at a certain concentration or higher without hindering the airflow handled by the ventilation system or excessively increasing pressure loss.

[0012] Ultimately, in order for the use of phytoncides to fully demonstrate their advantages in improving indoor air quality, the inconveniences of installation and management and the problem of maintaining concentration revealed in existing methods must be resolved.

[0013] Accordingly, there is an increasing need for technology that allows for the easy replacement of phytoncide solutions or devices, supplies phytoncide substances at a uniform concentration indoors, and uniformly releases phytoncides without compromising the performance of ventilation systems.

[0014]

[0015] The present invention aims to solve the aforementioned problems, and the objective of the present invention is to provide an effective substance supply device coupled to the outside of a ventilation device to facilitate the smooth diffusion of an effective substance, and an effective substance supply system including the same.

[0016] The problems of the present invention are not limited to those mentioned above, and other unmentioned problems will be clearly understood by a person skilled in the art to which the present invention pertains from the description below.

[0025] At this time, an effective substance supply device may be provided, wherein the housing comprises: a cap coupled to the other end of the first flow path; and a body detachably coupled to the cap and having the storage space inside.

[0026] At this time, an active substance supply device may be provided, wherein the active substance is phytoncide.

[0027] At this time, an effective substance supply device may be provided in which the effective substance is contained within the housing in a form in which phytoncide water and phytoncide essential oil are mixed.

[0028] At this time, an effective substance supply device may be provided in which the effective substance is received in a state absorbed by a superabsorbent resin unit having a predetermined diameter, and a plurality of the superabsorbent resin units are received within the housing.

[0053] Hereinafter, embodiments of the present invention are described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. The present invention may be embodied in various different forms and is not limited to the embodiments described herein. In the drawings, parts unrelated to the explanation have been omitted to clearly explain the present invention, and the same reference numerals have been used for identical or similar components throughout the specification.

[0054] The words and terms used in this specification and claims are not limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention in accordance with the principles by which the inventor defines terms and concepts to best describe his invention.

[0055] In this specification, terms such as “comprising” or “having” are intended to describe the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should not be understood as precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0056] In describing the drawings below, each direction is defined and described based on the coordinate axes shown in FIG. 1. More specifically, the positive direction of the y-axis is defined as the upward side and the negative direction of the y-axis is defined as the downward side. The positive direction of the x-axis is defined as the right side and the negative direction of the x-axis is defined as the left side. The positive direction of the x-axis is defined as the forward side and the negative direction of the x-axis is defined as the rear side.

[0057] Thickness or size has been exaggerated in the drawings to clearly express the characteristics of the configuration, and the thickness or size of the configuration shown in the drawings is not necessarily the same as the actual value.

[0058] In the following description, descriptions of some components may be omitted to clarify the features of the present invention.

[0059] An effective substance supply device and an effective substance supply system including the same according to one embodiment of the present invention are an effective substance supply device and an effective substance supply system including the same for supplying an effective substance indoors in conjunction with a ventilation device.

[0060] In this case, the active substance may be phytoncide as an example, but the present invention is not limited to cases where the active substance is phytoncide.

[0061] Although the active substance described in this specification is exemplified by phytoncide, it is not limited to the application of other substances other than phytoncide that improve indoor air quality or are desired by the user as active substances.

[0062] FIG. 1 is a cross-sectional view illustrating an effective substance supply system according to one embodiment of the present invention. FIG. 2 is a cross-sectional view illustrating a modified example of an effective substance supply system according to one embodiment of the present invention. FIG. 3 is a cross-sectional view illustrating an effective substance supply device according to one embodiment of the present invention. FIG. 4 is an enlarged view illustrating part A of FIG. 3. FIG. 5 is a cross-sectional view illustrating the operation of an effective substance supply device according to one embodiment of the present invention.

[0063] Referring to FIG. 1 and FIG. 2, an effective substance supply system (1) according to one embodiment of the present invention may include a ventilation device (30) for ventilating outside air and inside air entering and exiting a room (3), a pipe (40) connected to the ventilation device (30), and an effective substance supply device (2) mounted on the pipe (40).

[0064] At this time, as shown in FIG. 1, the effective substance supply device (2) may be mounted on the pipe (40) outside the room (3), but is not necessarily limited thereto, and the effective substance supply device (2) may also be mounted on the pipe (40) inside the room (3).

[0065] In the case of the piping (40), it may include a first part (42) extending from the ventilation device (30) toward the room (3) and a second part (44) located at the end of the first part (42).

[0066] The second part (44) can be extended in a direction that forms a predetermined angle with the extension direction of the first part (42).

[0067] For example, the second part (44) can be extended upward from the end of the first part (42).

[0068] The end of the second part (44) can be located at the top within the room (3).

[0069] Accordingly, the effective substance (50) supplied through the end of the second part (44) can enter the room (3) from the upper part of the room (3). In addition, unlike the lower part where various structures constituting the room (3) are arranged, since the effective substance (50) diffuses first from the upper part of the room (3), obstacles that obstruct the diffusion path of the effective substance (50) can be minimized, thereby enabling smooth diffusion of the effective substance (50).

[0070] Meanwhile, the second part (44) may extend toward the top of the room (3), that is, toward the ceiling. Additionally, the second part (44) may be positioned on the inner side of the room (3), that is, near the wall.

[0071] Accordingly, as the effective substance (50) supplied through the second part (44) diffuses within the room (3), the effective substance (50) can be smoothly diffused along the walls and ceiling within the room (3) by the Coanda effect, in which the fluid flows along the surface of an object.

[0072] The effective substance (50) supplied into the room (3) through the end of the second part (44) can be smoothly diffused to other locations within the room (3) far from the end of the second part (44) without being concentrated at the end of the second part (44).

[0073] Meanwhile, an effective substance supply device (2) according to one embodiment of the present invention can be mounted on the first part (42).

[0074] In FIGS. 1 and 2, the first part (42) is shown extending in one direction, but the first part (42) is not necessarily limited to extending only in one direction.

[0075] The first part (42) may be formed in a shape that extends in one direction, but it is not limited to extending by changing direction one or more times.

[0076] The effective substance supply device (2) can be mounted on the first part (42) by penetrating a position on the side of the first part (42).

[0077] Referring to FIGS. 3 and 5, the effective substance supply device (2) may include a housing (10) having a storage space (11) in which an effective substance (50) is stored, a first flow path (16) whose lower end penetrates the housing (10) and is connected to the storage space (11), and whose upper end penetrates the side of the first part (42), and a pipe (20) located within the first part (42) and connected to the first flow path (16).

[0078] At this time, the pipe (20) can be formed in a shape that extends in a direction parallel to the extension direction of the first part (42) of the piping (40).

[0079] More specifically, the pipe (20) can be extended in a direction parallel to the extension direction of the first part (42) at one position of the first part (42) where the pipe (20) is located.

[0080] For example, if the pipe (20) is extended in one direction of the first part (42) and then bent to extend in another direction, the pipe (20) may be extended in a direction parallel to the extension direction of the first part (42) at one position of the first part (42) where the pipe (20) is located.

[0081] For example, if the first part (42) extends in one direction at a point where the pipe (20) is located, and the first part (42) extends in a different direction at another point of the first part (42), the pipe (20) can be extended in the said one direction.

[0082] At this time, the pipe (20) can be formed in a shape where both the front and rear are open along the extension direction.

[0083] For example, as shown in FIG. 3, when the first part (42) is extended in the left-right direction and the pipe (20) is also extended in the left-right direction accordingly, the left end and the right end of the pipe (20) can both be formed in an open shape.

[0084] In this way, the end located at the rear along the extension direction of the pipe (20) among the two open ends of the pipe (20) can be defined as the first end (21), and the end located at the front along the extension direction of the pipe (20) among the two open ends of the pipe (20) can be defined as the second end (22).

[0085] At this time, when comparing the cross-sections cut perpendicular to the extension direction of the pipe (20), the cross-sectional area (S1) of the first end (21) can be formed to be larger than the cross-sectional area (S2) of the second end (22).

[0086] In addition, a first flow path (16) may be connected to the pipe (20) by penetrating the side of the pipe (20) in a lateral direction with respect to the extension direction of the pipe (20).

[0087] At this time, since the first end (21) and the second end (22) of the pipe (20) are both open and the pipe (20) is located within the piping (40), as shown in FIG. 5, some of the fluid flow formed within the piping (40) can pass through the pipe (20).

[0088] At this time, as the fluid passes through the pipe (20), the effective substance (50) stored in the storage space (11) of the housing (10) may be discharged through the first flow path (16) connected to the side of the pipe (20).

[0089] The active material (50) can be supplied into the room (3) through the second part (44) along with the fluid flow in the piping (40) by passing through the first flow path (16) and the second end (22) of the pipe (20) in sequence.

[0090] Figure 6 is a graph showing the change in the concentration of an active substance when using a conventional active substance supply system.

[0091] The y-axis of the graph shown in FIG. 6 is an axis representing TVOC (Total Volatile Organic Compounds), which is an axis representing the concentration of the total amount of volatile organic compound particles formed in the room (3). The x-axis of the graph shown in FIG. 6 represents the passage of time.

[0092] In the past, as shown in Fig. 6, phytoncide water was mainly used to supply phytoncide, so the concentration of phytoncide formed in the room (3) was not high.

[0093] The active substance (50) stored in the storage space (11) of the active substance supply device (2) according to one embodiment of the present invention may be formed by mixing two or more substances.

[0094] For example, the active substance (50) can be formed by mixing phytoncide water and phytoncide essential oil.

[0095] There is a problem in that the amount of phytoncide evaporated per hour is so small that the concentration of phytoncide formed in the room (3) is so small that it is difficult to measure the phytoncide with a general phytoncide measuring device.

[0096] On the other hand, while phytoncide essential oils may have a high amount of phytoncide evaporated per hour, there is a problem that the replacement cycle may become excessively frequent because the phytoncide can be consumed quickly.

[0097] Accordingly, when phytoncide essential oil and phytoncide water are mixed and used at a concentration within an appropriate range, phytoncide can be supplied at an appropriate concentration within the room (3) while also ensuring sustained release.

[0098] In the case of an effective substance supply device (2) and an effective substance supply system (1) including the same according to one embodiment of the present invention, the phytoncide essential oil may be blended in an amount of 1% to 10% of the mixture of phytoncide essential oil and phytoncide water.

[0099] Preferably, the active substance supply device (2) and the active substance supply system (1) including the same according to one embodiment of the present invention may be formulated such that the amount of phytoncide essential oil is within 1% to 3% of the mixture of phytoncide essential oil and phytoncide water.

[0100] At this time, the mixture of phytoncide essential oil and phytoncide water can be provided in a form absorbed into granules composed of a predetermined superabsorbent resin unit (52).

[0101] Referring to FIG. 4, the superabsorbent resin unit (52) can be formed to have a predetermined diameter (R).

[0102] At this time, the amount of effective material (50) supplied over time can be controlled according to the size of the diameter (R) of the superabsorbent resin unit (52).

[0103] For example, when an effective substance (50) is absorbed into a superabsorbent resin unit (52) with a large diameter (R), the total surface area may be reduced compared to when an effective substance (50) is absorbed into a superabsorbent resin unit (52) with a small diameter (R).

[0104] Accordingly, the amount of active substance (50) supplied per hour can be reduced, and conversely, the sustained release can be improved.

[0105] Conversely, when the effective substance (50) is absorbed into a superabsorbent resin unit (52) with a small diameter (R), the total surface area can be increased compared to when the effective substance (50) is absorbed into a superabsorbent resin unit (52) with a large diameter (R).

[0106] Accordingly, the amount of active substance (50) supplied per hour can be increased, and conversely, the sustained release can be reduced.

[0107] Accordingly, depending on the ratio of the constituent materials of the active substance, such as the ratio of phytoncide essential oil to phytoncide water, and the size and shape of the superabsorbent resin unit (52) that absorbs and supplies the active substance, the active substance supply device (2) and the active substance supply system (1) including the same according to one embodiment of the present invention can control the hourly supply amount and sustained release of the active substance (50).

[0108] FIG. 7 is a cross-sectional view illustrating an active substance supply device according to an embodiment of the present invention including a sensor and an alarm. FIG. 8 is a cross-sectional view illustrating an alarm operating when the amount of active substance stored in the active substance supply device according to an embodiment of the present invention is below a predetermined threshold. FIG. 9 is a graph showing the change in the concentration of an active substance when using an active substance supply system according to an embodiment of the present invention.

[0109] The graph in FIG. 9 shows the change in TVOC appearing in the room (3) as the active substance (50) stored in the active substance supply device (2) according to one embodiment of the present invention begins to evaporate, and the change in weight of the active substance (50) stored in the active substance supply device (2).

[0110] As described, the weight of the active substance (50) stored in the active substance supply device (2) decreases over time as the active substance (50) evaporates, and the TVOC concentration in the room (3) increases rapidly as the active substance (50) evaporates, and then decreases rapidly at a specific point in time.

[0111] As such, since the effective substance (50) stored in the effective substance supply device (2) is depleted over time, replacement of the effective substance (50) is necessary for the effective substance supply device (2) and the effective substance supply system (1) including it to maintain smooth performance.

[0112] As shown in FIG. 9, if the weight of the active substance (50) stored in the active substance supply device (2) falls below a predetermined standard value, the supply amount of the active substance (50) may be reduced.

[0113] Accordingly, an effective substance supply device (2) and an effective substance supply system (1) including the same according to one embodiment of the present invention may further include a sensor (60) for sensing the amount of effective substance (50) stored in the effective substance supply device (2) and an alarm (70).

[0114] At this time, the sensor (60) can sense the weight of the effective substance (50) stored in the effective substance supply device (2), and if the weight of the effective substance (50) sensed by the sensor (60) is less than or equal to a predetermined standard value, the sensor (60) can transmit a signal to the alarm (70).

[0115] Accordingly, when the weight of the active substance (50) stored in the active substance supply device (2) is below a predetermined standard value, an alarm (70) may sound to inform the user that the active substance needs to be replaced.

[0116] FIG. 10 is a front view illustrating an effective substance supply device according to an embodiment of the present invention. FIG. 11 is a drawing illustrating the door of the effective substance supply device according to an embodiment of the present invention opened. FIG. 12 is a drawing illustrating the effective substance being introduced into the effective substance supply device of FIG. 9.

[0117] Referring to FIGS. 10 to 12, an effective substance supply device (2) according to one embodiment of the present invention is provided with a door (18) in a housing (10), so that an effective substance (50) can be replaced and filled in a storage space (11) inside the housing (10) through the door (18).

[0118] At this time, the active substance (50) may be filled directly into the storage space (11), or it may be filled into the storage space (11) while contained in a separate container.

[0119] Additionally, in the illustrated embodiment, a configuration in which a door (18) is installed on the side of the housing (10) is disclosed, but this is exemplary and is not necessarily limited thereto.

[0120] For example, a door (18) may be installed on the bottom surface of the housing (10) so that the active material (50) can be replaced through the bottom surface of the housing (10).

[0121] The location and direction in which the effective material (50) is replaced in this manner are not limited as long as the effective material (50) can be filled into the storage space (11) of the housing (10).

[0122] Accordingly, the effective substance supply device (2) and the effective substance supply system (1) including the same according to one embodiment of the present invention can easily replace and refill the effective substance (50) by opening and closing the door (18) from the outside of the pipe (40) without the need to disassemble the ventilation device (30) or disassemble the pipe (40) for replacing and refilling the effective substance (50).

[0123] FIG. 13 is a cross-sectional view illustrating a modified example of an effective substance supply device according to an embodiment of the present invention. FIG. 14 is a cross-sectional view illustrating the body of the effective substance supply device of FIG. 13 removed. FIG. 15 is a cross-sectional view illustrating the body of the effective substance supply device of FIG. 13 replaced and aligned. FIG. 16 is a cross-sectional view illustrating the body of the effective substance supply device of FIG. 14 replaced and mounted.

[0124] An effective substance supply device (2) according to one embodiment of the present invention may be composed of a cap (14) coupled with a first flow path (16) and a body (12) coupled to the cap (14).

[0125] At this time, the body (12) can be detachably connected to the cap (14).

[0126] For example, the body (12) may be provided with a screw thread (19) corresponding to the cap (14) and may be rotatably coupled. However, the coupling structure and method of the body (12) and the cap (14) are not necessarily limited to this, and it is sufficient that the body (12) and the cap (14) are detachably coupled.

[0127] At this time, the body (12) may be provided in a cartridge type in which an effective substance (50) is stored.

[0128] In this case, a storage space (11) may be provided inside the body (12), and an effective substance (50) may be accommodated inside the body (12).

[0129] Accordingly, the active material (50) can be easily replaced as the cartridge-type body (12) is replaced.

[0130] This structure is exemplary and is not necessarily limited thereto.

[0131] For example, FIGS. 13 to 16 describe a structure in which the cap (14) is fixed and the body (12) is replaceable, but the cap (14) and the body (12) are not limited to being replaced as a single unit.

[0132] In this case, with the first Euro (15) and pipe (20) mounted on the piping (40), the cap (14) and body (12) can be separated from the first Euro (15) and replaced.

[0133] In this way, when the first Euro (15) and pipe (20) are mounted on the piping (40), the body (12) can be replaced, or the cap (14) and the body (12) can be replaced, thereby allowing the effective material (50) to be easily replaced without disassembling the ventilation device (30) or the piping (40).

[0134] In addition, the effective substance supply device (2) and the effective substance supply system (1) including the same according to one embodiment of the present invention are mounted on a pipe (40) located outside the ventilation device (30) without affecting the ventilation device (30), so the design of the ventilation device (30) is not changed or performance degradation is not caused for the supply of the effective substance (50).

[0135] In addition, as the effective substance supply device (2) is installed in the pipe (40), it can be connected to the existing ventilation device (30) which is unrelated to the effective substance (50) supply function, thereby minimizing the impact on the design of the ventilation system.

[0136] In addition, since only a pipe (20) having a much smaller cross-sectional area than a part of the first flow path (16) and the cross-sectional area of ​​the pipe (40) is placed within the pipe (40), the effective substance supply device (2) and the effective substance supply system (1) including it do not hinder the fluid flow within the pipe (40) or cause pressure loss.

[0137] Although embodiments of the present invention have been described above, the spirit of the present invention is not limited to the embodiments presented in this specification. Those skilled in the art who understand the spirit of the present invention may easily propose other embodiments within the scope of the same spirit by adding, changing, deleting, or adding components, and such embodiments shall also be considered to fall within the scope of the spirit of the present invention.
