Description

Technical Field

[0001] The present invention relates to a chemical vaporizer comprising a chemical vaporizer holding a room-temperature volatile chemical and a container for housing the chemical vaporizer.

Background Art

[0002] The indoor unit of an air conditioner takes in indoor air from an intake port, performs heat exchange with heat exchange fins, and discharges the air into the room to adjust the indoor air. Due to long-term operation, dirt such as dust, oil, and tobacco tar contained in the air adheres to the inside of the indoor unit of the air conditioner (especially the fins), causing problems such as the generation of bad odors due to the growth of bacteria and mold.

[0003] Therefore, a permanent-type chemical vaporizer has been proposed that suppresses the growth of bacteria and mold in the indoor unit of an air conditioner by allowing the volatilized chemical to be taken into the indoor unit of the air conditioner from the intake port. However, conventional chemical vaporizers have a vaporization port only on the side opposite to the surface of the container housing the chemical vaporizer that contacts the housing of the air conditioner. For this reason, there has been a problem that the volatilized chemical cannot be efficiently taken into the indoor unit of the air conditioner.

Summary of the Invention

Problems to be Solved by the Invention

[0004] The present invention has been made in view of the above circumstances, and an object thereof is to provide a chemical vaporizer capable of efficiently taking the volatilized chemical into the indoor unit of an air conditioner.

Means for Solving the Problems

[0005] In order to achieve the above object, the chemical vaporizer according to the present invention is characterized by the following [1] to [5]. [1] A chemical vaporizer comprising a chemical vaporizer holding a room-temperature volatile chemical and a container for housing the chemical vaporizer, The container comprises a rear wall portion, a front wall portion facing the rear wall portion, and a first side wall portion connected between the rear wall portion and the front wall portion. The first side wall portion is connected to the rear wall portion and has an inclined portion that moves away from the rear wall portion and approaches the front wall portion, and is directed outward from the container. The inclined portion is provided with a first opening. It must be a pesticide volatilization device. [2] [1] A drug volatilization device as described above, The first openings are arranged in a row along the edge of the rear wall portion to which the first side wall portions are connected. It must be a pesticide volatilization device. [3] A drug volatilization device as described in [1] or [2], The first side wall portions are provided in pairs facing each other, The container comprises a pair of second side walls connected between the rear wall and the front wall, facing each other in an intersecting direction that intersects with the opposing direction of the pair of first side walls, One of the pair of second side walls is provided with a second opening on the rear wall side of the drug volatilizer. It must be a pesticide volatilization device. [4] [3] A drug volatilization device as described above, One of the pair of second side walls is provided with a third opening on the front wall side of the second opening for inserting the volatile chemical into the container. It must be a pesticide volatilization device. [5] A drug volatilization device as described in [3] or [4], A fourth opening is provided on the other of the pair of second side walls for visually inspecting the volatile substance of the drug. The container is provided with a covering wall portion that covers the rear wall portion of the fourth opening, which is more than the drug volatilizer portion. It must be a pesticide volatilization device.

[0006] According to the chemical volatilization device with the configuration described in [1] above, if the rear wall is positioned facing the air intake of the indoor unit of the air conditioner, a gap is created between the first opening and the air intake, making it easier for air to flow toward the air intake opposite the first opening. The volatilized chemical is taken into the indoor unit of the air conditioner by this airflow, so the volatilized chemical can be efficiently taken into the indoor unit of the air conditioner. In the drug volatilization device with the configuration described in [2] above, the first openings are arranged in a row along the edge of the rear wall portion where the first side walls are connected. This allows the drug to be volatilized over a wide area while maintaining the strength of the container. In the chemical volatilization device with the configuration described in [3] above, a second opening is provided on one of the pair of second side walls, on the side of the rear wall relative to the chemical volatilizer. This creates a passage for air that enters the container through the second opening and exits the container 3 through the first opening, allowing the volatilized chemical to be more efficiently taken into the indoor unit of the air conditioner. In the drug volatilization device with the configuration described in [4] above, one of the pair of second side walls is provided with a third opening on the front wall side of the second opening for inserting the drug volatilizer into the container. This allows the drug volatilizer to be slid into the container through the third opening. In the drug volatilization device with the configuration described in [5] above, the covering wall covers the rear wall portion of the fourth opening for visualizing the drug volatilization material. This makes it easier to confirm the amount of drug inside the drug volatilization material. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a chemical volatilization device that can efficiently take in volatilized chemicals into the indoor unit of an air conditioner.

[0008] The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by referring to the attached drawings and reading through the embodiments for carrying out the invention described below (hereinafter referred to as "embodiments").

[Figure 6] Figure 6 is an explanatory diagram for explaining the effect of the chemical agent volatilizing device shown in Figure 1.

Embodiments for Carrying Out the Invention

[0010] Specific embodiments of the present invention will be described below with reference to the respective figures.

[0011] As shown in Figure 5, the chemical agent volatilizing device 1 of the present embodiment is arranged around the intake port 11 of the air conditioner indoor unit 10. The chemical agent volatilizing device 1 of the present embodiment volatilizes a chemical agent that suppresses the growth of bacteria and mold, and causes it to be taken into the air conditioner indoor unit 10 from the intake port 11.

[0012] (Configuration of the Chemical Agent Volatilizing Device) As shown in Figure 1, the chemical agent volatilizing device 1 of the present embodiment is provided in a substantially rectangular shape. For the convenience of explanation, as shown in Figure 1, the longitudinal direction of the chemical agent volatilizing device 1 is defined as the "vertical direction", the short side direction is defined as the "left - right direction", and the thickness direction is defined as the "front - back direction". These vertical direction, left - right direction, and front - back direction are perpendicular to each other.

[0013] The chemical agent volatilizing device 1 of the present embodiment includes a chemical liquid capsule 2 as a chemical agent volatilizing body that holds a chemical agent with normal - temperature volatility, and a container 3 that houses the chemical liquid capsule 2.

[0014] The drug capsule 2 comprises a capsule body 21, a permeable film (not shown), and an impermeable film (not shown). The capsule body 21 integrally provides a recess 22 for containing a liquid drug and a flange portion 23 protruding from the edge of the recess 22. The recess 22 has a substantially rectangular bottom wall 221 and a peripheral wall 222 that rises from the edge of the bottom wall 221 to the rear. The flange portion 23 is provided protruding from the rear end of the peripheral wall 222 in a direction perpendicular to the peripheral wall 222.

[0015] A permeable film (not shown) covers the opening of the recess 22 and the flange portion 23. The permeable film is made of a translucent resin material and is configured to allow volatile drugs to pass through but not non-volatile drugs. The permeable film can be made of, for example, linear low-density polyethylene (LLDPE). An impermeable film (not shown) covers the permeable film. The impermeable film has the property of not allowing volatile drugs and liquid drugs to pass through, and examples include aluminum film, polyester film, polyamide film, polyacetal film, etc. When the impermeable film is peeled off, the drug contained in the recess 22 is volatilized through the permeable film. After the impermeable film is peeled off, the drug capsule 2 is placed in the container 3 (described later) with the capsule body 21 facing forward and the permeable film facing backward.

[0016] As shown in Figure 1, the container 3 comprises a rear wall portion 4 (see Figure 2), a front wall portion 5 facing the rear wall portion 4 in the front-rear direction, a pair of side wall portions 6, 6 (first side wall portion) connected between the left-right ends of the rear wall portion 4 and the front wall portion 5, and an upper wall portion 71 and a lower wall portion 72 (see Figure 4) connected between the vertical ends of the rear wall portion 4 and the front wall portion 5. As shown in Figure 2, the rear wall portion 4 is provided as a flat plate perpendicular to the front-rear direction and as a roughly rectangular shape that is elongated in the vertical direction. A roughly square recess 41 for attaching a fixing member is provided in the center of the rear wall portion 4. The recess 41 is recessed toward the front. Examples of fixing members include double-sided tape, hooks, hook-and-loop fasteners, and elastomers. Elastomers are particularly desirable because they can be fixed to any location and do not leave any adhesive residue.

[0017] As shown in Figure 1, the front wall portion 5, like the rear wall portion 4, is provided in a flat plate shape perpendicular to the front-rear direction, and is also provided in a roughly rectangular shape that is elongated in the vertical direction. An opening 51 is provided in the center of the front wall portion 5.

[0018] The pair of side walls 6, 6 are arranged facing each other in the left-right direction (opposing direction). Each of the pair of side walls 6, 6 has an inclined portion 61 provided on the rear wall 4 side and an inclined portion 62 provided on the front wall 5 side. As shown in Figure 2, the inclined portion 61 is connected to the rear wall 4, moves away from the rear wall 4, and is arranged to move outwards from the container 3 as it approaches the front wall 5. As shown in Figure 1, the inclined portion 62 is connected to the front wall 5, moves away from the front wall 5, and is arranged to move outwards from the container 3 as it approaches the rear wall 4.

[0019] In this embodiment, the inclined portions 61 and 62 are provided extending from the upper end to the lower end of the rear wall portion 4 and the front wall portion 5. In this embodiment, the inclined portions 61 and 62 are provided in a curved plate shape that protrudes outward. As shown in Figure 2, an opening 63 (first opening) is provided in the inclined portion 61 on the rear wall portion 4 side. In this embodiment, four openings 63 are provided arranged vertically.

[0020] The upper wall portion 71 (one of a pair of second side walls) and the lower wall portion 72 (the other of a pair of second side walls) shown in Figures 3 and 4 are provided opposite each other in the vertical direction (intersecting direction) that is perpendicular (intersecting) to the left-right direction. The upper wall portion 71 is provided with an opening 73, as shown in Figure 3. The opening 73 is provided with two interconnected openings: an opening 731 (second opening) for creating an air passage on the rear side of the drug capsule 2 and an opening 732 (third opening) for inserting the drug capsule 2 into the container 3.

[0021] The opening 731 is located on the upper wall portion 71, on the rear wall portion 4 side of the drug capsule 2 housed in the container 3. The opening 731 is designed so that its length in the left-right direction decreases as it approaches the rear. The longest left-right length of the opening 731 is shorter than the left-right length of the recess 22. Therefore, the recess 22 cannot be inserted through this opening 731, and the recess 22 cannot be mistakenly inserted with the front facing forward.

[0022] The opening 732 is provided on the front wall portion 5 side of the opening 731. The opening 732 is provided in a shape that is almost the same as the outer shape of the drug capsule 2 when viewed from above. When the drug capsule 2 is inserted into the container 3 through this opening 732, the flange portion 23 is inserted into a press-fit portion (not shown) provided inside the container 3, and the drug capsule 2 is held inside the container 3. The drug capsule 2 is positioned in front of the opening 63 provided in the inclined portion 61 described above inside the container 3.

[0023] As shown in Figure 4, an opening 74 (fourth opening) is provided in the lower wall portion 72. In this embodiment, the opening 74 is provided in an elongated oval shape that is long in the left-right direction. The container 3 is also provided with a covering wall portion 8 that covers the opening 74 from the inside of the container 3. The covering wall portion 8 covers the part of the opening 74 that is on the rear wall portion 4 side of the recess 22. The covering wall portion 8 has an opening 81 only in the part that is vertically opposite to the recess 22. The recess 22 can be seen through this opening 81, and the amount of drug contained in the recess 22 can be confirmed. In addition, since the part other than the recess 22 is hidden by the covering wall portion 8, it is easy to confirm the amount of drug contained in the recess 22. Furthermore, in this embodiment, an opening 51 is provided in the front wall portion 5 of the container 3. The presence of this opening 51 allows light to enter the container 3, making it brighter, which makes it even easier to confirm the amount of drug solution.

[0024] (Example of pesticide volatilization device installation) Next, an example of installing the chemical volatilization device 1 with the above-described configuration on an air conditioner indoor unit 10 will be explained with reference to Figure 5. The air conditioner indoor unit 10 shown in Figure 5 has multiple air intake ports 11 on the upper part of the housing 12. The air intake ports 11 are covered by a filter 13 from the inside of the housing 12. The chemical volatilization device 1 is positioned on the upper part of the air conditioner indoor unit 10 with the rear wall portion 4 facing downwards.

[0025] (Effects of the chemical volatilization device) Next, the effects of the chemical volatilization device 1 with the above-described configuration will be explained with reference to Figure 6. The chemical volatilization device 1 of this embodiment has an inclined portion 61 that is connected to the rear wall portion 4, moves away from the rear wall portion 4, and approaches the front wall portion 5, and is directed toward the outside of the container 3, and an opening 63 is provided in the inclined portion 61. As a result, a gap is created between the opening 63 and the air intake port 11, and as shown by the arrow in the figure, air can easily flow toward the air intake port 11 opposite the opening 63. The volatilized chemical is taken into the air conditioner indoor unit 10 by this airflow, so the volatilized chemical can be efficiently taken into the air conditioner indoor unit 10.

[0026] Furthermore, in the drug volatilization device 1 of this embodiment, multiple openings 63 are provided in a row along the edge of the rear wall portion 4, which is connected to the side wall portions 6. This allows the drug to be volatilized over a wide area while maintaining the strength of the container 3.

[0027] Furthermore, in the drug volatilization device 1 of this embodiment, an opening 731 is provided in the upper wall portion 71 at a position closer to the rear wall portion 4 than the drug capsule 2. This creates a passage for air that enters the container 3 from the opening 731 and exits the container 3 through the opening 63, allowing the volatilized drug to be more efficiently taken into the indoor unit 10 of the air conditioner.

[0028] Furthermore, in the drug volatilization device 1 of this embodiment, the upper wall portion 71 is provided with an opening 732 that communicates with the front wall portion 5 side of the opening 731 and allows the drug capsule 2 to be inserted into the container 3. This allows the drug capsule 2 to be slid into the container 3 through the opening 732.

[0029] Furthermore, in the drug volatilization device 1 of this embodiment, the covering wall portion 8 covers the opening 74 on the rear wall portion 4 side of the drug capsule 2. This makes it easier to check the amount of drug inside the drug capsule 2.

[0030] Next, the inventors conducted the following tests to confirm the effects described above. Two indoor air conditioner units 10 were cleaned with an existing cleaning agent to remove almost all mold. The chemical volatilization device 1 of this embodiment was installed around the air intake 11 on the top surface of one of the two indoor air conditioner units 10, while nothing was installed on the other. Mold samples were collected after one month and two months. As a result, it was found that the indoor air conditioner unit 10 with the chemical volatilization device 1 installed had less mold than the indoor air conditioner unit 10 with nothing installed, indicating that mold growth can be suppressed, that is, the volatilized chemical can be efficiently taken into the indoor air conditioner unit 10.

[0031] Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited, as long as they can achieve the present invention.

[0032] For example, a mirror may be provided on the outer surface of the rear wall portion 4 of the container 3. The mirror may be made of a mirror seal and attached to the rear wall portion 4, or it may be formed by printing or other means. By providing a mirror on the rear wall portion 4, the area around the air intake port 11 can be visually inspected, making it easier to install the chemical volatilization device 1 in an air conditioner.

[0033] Furthermore, although the inclined portions 61 and 62 were provided in a curved plate shape according to the above-described embodiment, the invention is not limited to this. The inclined portions 61 and 62 may also be provided in a flat plate shape.

[0034] In the embodiment described above, multiple openings 63 were provided in a line with the edge of the rear wall portion 4, but this is not the only option. A single opening 63, which is elongated in the vertical direction, may also be provided.

[0035] In the embodiment described above, the openings 731 and 732 provided in the upper wall portion 71 were in communication with each other, but this is not the only configuration. The openings 731 and 732 may be provided independently.

[0036] In the embodiment described above, the upper wall portion 71 was provided with an opening 731 located on the rear wall portion 4 side of the drug capsule 2, but this is not the only configuration. Providing the opening 731 is not essential and may be omitted.

[0037] In the embodiment described above, the upper wall portion 71 was provided with an opening 732 for inserting the drug capsule 2 into the container 3, but this is not the only option. For example, if the container 3 is divided into two parts and configured to accommodate the drug capsule 2, providing the opening 732 is not essential and may be omitted.

[0038] In the embodiment described above, the covering wall portion 8 was provided inside the lower wall portion 72, but this is not the only option. The covering wall portion 8 may be provided on the same plane as the lower wall portion 72, or it may be provided outside the lower wall portion. Furthermore, providing the covering wall portion 8 is not essential and may be omitted.

[0039] According to the embodiment described above, the drug capsule 2 contained an agent that suppresses the growth of microorganisms such as bacteria and mold, but it is not limited to this. The agent can be any agent that is volatile at room temperature, and may be an agent that is effective for deodorizing, fragrance, insect repellent, etc. [Explanation of symbols]
