Description

Technical Field

[0001] This application discloses an air direction adjustment device for an air conditioner outlet and an air conditioner.

Background Art

[0002] In recent years, air conditioners for indoor air conditioning have been installed in various buildings such as buildings, stores, hospitals, and houses. There are types of air conditioners that are embedded in ceilings, walls, etc., types that are suspended from the ceiling, and types that are installed on the wall surface, but all of them are common in that they are equipped with an air conditioner outlet that blows out air-conditioned air into the room.

[0003] By the way, since the specific gravity of air is inversely proportional to temperature, warm air accumulates at the upper part of the room. Also, cold air accumulates at the lower part of the room. Therefore, when the air conditioner performs a cooling operation, for example, in order to efficiently suck in the warm air that accumulates at the upper part of the room and perform air conditioning, the air conditioner blows out cold air from the air conditioner outlet toward the lower part of the room. Therefore, in order to avoid the cold air blown out from the air conditioner outlet hitting people in the room, for example, an instrument for adjusting the air direction of the air conditioner outlet, as shown in Patent Document 1, is commercially available.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In recent years, due to the improvement of hygiene awareness, a sterilizing component that exhibits a sterilizing effect has been volatilized in the indoor space. Also, in order to create a comfortable space, an aromatic component that exhibits a relaxation effect has been volatilized in the indoor space. When volatilizing such various active components in the indoor space, it is preferable from the viewpoint of diffusibility to arrange a member that volatilizes the active component near the air conditioner outlet.

[0006] An air-conditioning outlet is standardly equipped with an air direction adjusting device for adjusting the air direction on the air conditioner or is retrofitted by the user. In view of the diffusibility of the active ingredient, it is reasonable to attach a member containing the active ingredient to such an air direction adjusting device. However, for example, if such a member is attached to the plate surface responsible for air direction adjustment, it may cause turbulence in the air flow and adversely affect the air direction adjustment function.

[0007] Therefore, the present application discloses an air direction adjusting device and an air conditioner for an air-conditioning outlet that can attach a member that volatilizes an active ingredient while suppressing air flow turbulence as much as possible.

Means for Solving the Problem

[0008] To solve the above problems, in the present invention, a rod-shaped portion that extends in a rod shape along the edge on the air-conditioning outlet side of the plate-shaped air direction adjusting plate portion, has a surface in the shape of the outer peripheral surface of a cylinder, and has an accommodation space inside that can accommodate a volatile active ingredient is provided.

[0009] Specifically, the present invention is an air direction adjusting device for an air-conditioning outlet, which has a plate surface capable of adjusting the air direction of air, and is located inside or in front of an elongated air-conditioning outlet from which air conditioned by the air conditioner blows out. A plate-shaped air direction adjusting plate portion arranged to extend along the longitudinal direction of the air-conditioning outlet, and a rod-shaped portion that extends in a rod shape along the edge on the air-conditioning outlet side of the air direction adjusting plate portion, has a surface in the shape of the outer peripheral surface of a cylinder, and has an accommodation space inside that can accommodate a volatile active ingredient. It is provided with.

[0010] For the above air direction adjusting device, since the rod-shaped portion that accommodates the active ingredient forms a cylindrical outer peripheral surface, due to the Coanda effect, air flows along the outer peripheral surface of the rod-shaped portion toward the air direction adjusting plate portion. Therefore, even when the air that has passed through the rod-shaped portion flows to the air direction adjusting plate portion, the turbulence of the air flow on the surface of the air direction adjusting plate portion is suppressed as much as possible. Therefore, the air direction adjusting device can attach a member of the active ingredient carrying the active ingredient without impairing the air direction adjusting function that it originally should perform.

[0011] Note that the wind direction adjustment plate portion has an overall rectangular appearance, and the rod-shaped portion may extend in a rod shape along a portion corresponding to one of the two long sides of the rectangle in the wind direction adjustment plate portion. When the rod-shaped portion is provided in such a form, due to the Coandă effect, the air passing through the rod-shaped portion flows along the outer peripheral surface of the rod-shaped portion, so that the airflow passing through the rod-shaped portion is suppressed as much as possible from being disturbed on the surface of the wind direction adjustment plate portion. Therefore, the wind direction adjustment device can mount a member of the active ingredient carrying the active ingredient without impairing the wind direction adjustment function that it should originally perform.

[0012] Also, the wind direction adjustment plate portion may be formed so as to project from the outer peripheral surface of the cylinder. Even if the wind direction adjustment plate portion is provided in such a form with respect to the rod-shaped portion, due to the Coandă effect, the air passing through the rod-shaped portion flows along the outer peripheral surface of the rod-shaped portion, so that the disturbance of the airflow on the surface of the wind direction adjustment plate portion is suppressed as much as possible. Therefore, with such a wind direction adjustment device, it is possible to mount a member of the active ingredient carrying the active ingredient without impairing the wind direction adjustment function that it should originally perform.

[0013] Also, the rod-shaped portion may have a vent hole communicating the inside and outside of the accommodation space on the outer surface. With such a wind direction adjustment device, the active ingredient can be effectively diffused from the vent hole.

[0014] Also, the rod-shaped portion may have an access port at at least one of both ends of the rod-shaped portion through which the active ingredient can enter and exit the accommodation space. With such a wind direction adjustment device, it is easy to take in and out the active ingredient.

[0015] Also, the main body portion having the rod-shaped portion and the wind direction adjustment plate portion may further include a support portion that supports the wind direction adjustment plate portion in a state where it is located in front of the air conditioner outlet. With such a wind direction adjustment device, it is possible to arrange the wind direction adjustment plate portion in front of the air conditioner outlet.

[0016] Further, the wind direction adjustment plate portion may be disposed inside or in front of the air conditioner outlet by fitting the rod-shaped portion onto a shaft provided inside the air conditioner outlet. With such a wind direction adjustment device, it can be integrated with the air conditioner.

[0017] Further, the present invention may be an air conditioner provided with any of the above wind direction adjustment devices at the air conditioner outlet.

Effects of the Invention

[0018] With the above-described wind direction adjustment device for the air conditioner outlet and the air conditioner, while it is possible to mount a member that volatilizes an active ingredient, it is possible to suppress airflow disturbance as much as possible.

Modes for Carrying Out the Invention

[0020] Hereinafter, embodiments of the present invention will be described. The embodiments shown below are one form of the present invention, and the technical scope of the present invention is not limited to the following embodiments.

[0021] <Embodiment> FIG. 1 is an example of the mounting state of an air direction adjusting device 1 that adjusts the air direction of the air blown out from the air conditioning outlet of an air conditioner. As shown in FIG. 1, the air direction adjusting device 1 according to the present embodiment is disposed in front of an air conditioning outlet 102 provided in a ceiling-embedded air conditioner 101, and receives air-conditioned air blown out from the air conditioning outlet 102. It includes a main body 2, a support rod 3 that supports the main body 2 in a state where the main body 2 is disposed in front of the air conditioning outlet 102, and a base 4 that fixes the support rod 3 to the ceiling-embedded air conditioner 101. The air conditioning outlet 102 is an elongated opening. Further, the main body 2 is an air direction adjusting member having an appearance like a plate material abutted against a cylinder. And the support rod 3 can support the main body 2 in a state where the main body 2 extends along the longitudinal direction of the air conditioning outlet 102 in front of the air conditioning outlet 102.

[0022] FIG. 2 is a perspective view of the air direction adjusting device 1 viewed from the side. FIG. 3 is a perspective view of the air direction adjusting device 1 viewed from below.

[0023] The main body 2 is connected to the support rod 3 via a hinge 6. Further, the support rod 3 is connected to the base 4 via a hinge 5. The hinge 5 and the hinge 6 are hinges that can rotate with an appropriate fastening force. Therefore, the main body 2 and the support rod 3 do not relatively rotate around the axis of the hinge 6, and the support rod 3 and the base 4 do not relatively rotate around the axis of the hinge 5. For this reason, when the base 4 is inserted between the ceiling-embedded air conditioner 101 and the ceiling surface and fixed near the air conditioning outlet 102, the position and angle of the main body 2 with respect to the base 4 are adjusted by the hinge 5 and the hinge 6, so that the main body 2 can be fixed to the air conditioning outlet 102 in an appropriate position and posture.

[0024] The main body 2 has a wind direction adjustment plate portion 21 and a rod-shaped portion 22. The wind direction adjustment plate portion 21 has a plate surface capable of adjusting the wind direction of air, and is disposed in front of the elongated air-conditioning outlet 102 from which the air conditioned by the ceiling-embedded air conditioner 101 blows out, so as to extend along the longitudinal direction of the air-conditioning outlet 102. The wind direction adjustment plate portion 21 is a plate-shaped portion having an overall rectangular form. And the rod-shaped portion 22 extends in a rod shape along a portion corresponding to one of the two long sides of this rectangle. The rod-shaped portion 22 extends in a rod shape along the edge of the wind direction adjustment plate portion 21, and the surface is a portion in the shape of the outer peripheral surface of a cylinder. For this reason, the wind direction adjustment plate portion 21 protrudes from the outer peripheral surface of the cylinder formed by the rod-shaped portion 22, and the main body 2 presents a form in which the plate-shaped wind direction adjustment plate portion 21 abuts against the columnar rod-shaped portion 22.

[0025] The rod-shaped portion 22 has an accommodation space inside that can accommodate a member of a volatile active ingredient. For this reason, ventilation holes 26 communicating the inside and outside of the accommodation space are provided on the outer peripheral surface of the rod-shaped portion 22. Also, at both ends of the rod-shaped portion 22, there are access ports for taking in and out the member of the active ingredient, and these access ports are closed by lids 28. The ventilation holes 26 are elongated holes extending along the direction in which the air blowing out from the air-conditioning outlet 102 flows. A large number of ventilation holes 26 are arranged along the longitudinal direction of the rod-shaped portion 22. The ventilation holes 26 are formed so as to straddle the rod-shaped portion 22 and the wind direction adjustment plate portion 21 at the boundary portion between the rod-shaped portion 22 and the wind direction adjustment plate portion 21. Incidentally, the ventilation holes 26 may be omitted. For example, if the rod-shaped portion 22 is formed of a breathable material, it is possible to diffuse the active ingredient even if the ventilation holes 26 are omitted. The ventilation holes 26 are elongated holes extending along the direction in which the air blowing out from the air-conditioning outlet 102 flows. A large number of ventilation holes 26 are arranged along the longitudinal direction of the rod-shaped portion 22. The ventilation holes 26 are formed so as to straddle the rod-shaped portion 22 and the wind direction adjustment plate portion 21 at the boundary portion between the rod-shaped portion 22 and the wind direction adjustment plate portion 21. Incidentally, the ventilation holes 26 may be omitted. For example, if the rod-shaped portion 22 is formed of a breathable material, it is possible to diffuse the active ingredient even if the ventilation holes 26 are omitted.

[0026] Each part of the wind direction adjustment device 1 can be formed of resin, aluminum, or various other materials. In the case of resin, there is a possibility that inevitable warping may occur after thermoforming, so the main body 2 may be formed of a metal such as aluminum. When the main body 2 is formed of resin, a warping prevention means such as ribs may be provided on the wind direction adjustment plate portion 21.

[0027] FIG. 4 is a diagram showing how the member of the active ingredient is taken in and out. When the lids 28 provided at both ends of the rod-shaped part 22 are opened, the member 29 of the active ingredient accommodated in the accommodation space 25 can be taken in and out. Therefore, for example, it is possible to take out the member 29 of the active ingredient whose active ingredient has disappeared due to volatilization and replace it with a new member 29 of the active ingredient.

[0028] Examples of the active ingredient carried by the member 29 of the active ingredient include chlorine dioxide having a sterilizing ability, aromatic components such as hinoki that emits a pleasant fragrance, and various other drugs. By accommodating such drugs in the accommodation space 25, it becomes possible to volatilize these active ingredients into the indoor space.

[0029] In FIG. 4, the member 29 of the active ingredient in a cylindrical form is illustrated, but the member 29 of the active ingredient to be accommodated in the accommodation space 25 is not limited to such a form. The member 29 of the active ingredient may have a form other than a cylindrical shape, or may have a bag-like form.

[0030] FIG. 5 is a diagram showing the state of the air flow in the wind direction adjusting device 1. For comparison, FIG. 5(A) shows the state of the air flow in the embodiment, and FIG. 5(B) shows the state of the air flow in the comparative example.

[0031] For example, as shown in FIG. 5(B), in the wind direction adjusting device 50 in a form in which the accommodating portion 52 protrudes on the plate surface of the plate-shaped wind direction adjusting plate portion 51, the air flow is disturbed on the downstream side of the accommodating portion 52. Therefore, there is a possibility of adversely affecting the wind direction adjusting function that the wind direction adjusting device 50 should originally perform.

[0032] On the one hand, as shown in Fig. 5(A), in the main body 2 of the wind direction adjusting device 1, since the rod-shaped part 22 that houses the member 29 of the active ingredient in the accommodation space 25 forms a cylindrical outer peripheral surface, due to the Coandă effect, air flows along the outer peripheral surface of the rod-shaped part 22 toward the wind direction adjusting plate part 21. Therefore, the turbulence of the air flow on the surface of the wind direction adjusting plate part 21 is suppressed as much as possible. Thus, it can be said that the wind direction adjusting device 1 can mount the member 29 that volatilizes the active ingredient without impairing the wind direction adjusting function that it should originally perform.

[0033] Fig. 6 is a diagram showing the state of the air flow when the wind direction adjusting device 1 is attached to the ceiling-embedded air conditioner 101. Since the method of attaching the wind direction adjusting device 1 varies according to the user's preference, as shown in each of Figs. 6(A) to (C), the position and posture of the main body 2 with respect to the air conditioning outlet 102 also vary.

[0034] Therefore, for example, as shown by the dashed arrow in Fig. 6(A), when the air blown out from the air conditioning outlet 102 is blown toward the main body 2 by the louver 103 and flows through the rod-shaped part 22 and then to the wind direction adjusting plate part 21, due to the Coandă effect on the outer peripheral surface of the rod-shaped part 22 , air flows along the surface direction of the wind direction adjusting plate part 21 on both the upper surface side and the lower surface side of the wind direction adjusting plate part 21. In this case, as shown by the dashed arrow in Fig. 6(A), since the active ingredient carried on the member 29 of the active ingredient flows to both the upper surface side and the lower surface side of the wind direction adjusting plate part 21, it is possible to diffuse a relatively large amount of the active ingredient into the indoor space per unit time.

[0035] Also, for example, as shown by the dashed arrow in Fig. 6(B), when the air blown out from the air conditioning outlet 102 flows to the upper surface side of the wind direction adjusting plate part 21 by the louver 103, air flows along the surface direction of the wind direction adjusting plate part 21 on the upper surface side of the wind direction adjusting plate part 21. In this case, as shown by the dashed arrow in Fig. 6(B), since the active ingredient carried on the member 29 of the active ingredient flows to the upper surface side of the wind direction adjusting plate part 21, compared with the case of Fig. 6(A), it is possible to diffuse a relatively small amount of the active ingredient into the indoor space per unit time.

[0036] Further, for example, as shown in FIG. 6(C), when the rod-shaped portion 22 approaches the air suction port of the ceiling-embedded air conditioner 101, as indicated by the dashed arrow in FIG. 6(C), it is also possible to suck the active ingredient carried by the member 29 into the air suction port of the ceiling-embedded air conditioner 101. In this case, since the active ingredient sucked into the ceiling-embedded air conditioner 101 is mixed by the fan inside the ceiling-embedded air conditioner 101, it is possible to blow out the active ingredient from all the air conditioning outlets 102 of the ceiling-embedded air conditioner 101.

[0037] When the louver 103 is performing a swinging operation, the way the wind hits the main body 2 changes constantly. Therefore, when the louver 103 is performing a swinging operation, the wind hits the main body 2 in the form shown in FIG. 6(A) or in the form shown in FIG. 6(B). Since the air direction adjusting device 1 has the rod-shaped portion 22 forming a cylindrical outer peripheral surface, even when the wind hits in various forms, the turbulence of the air flow is suppressed as much as possible. Therefore, the active ingredient of the member 29 stored in the storage space 25 can be diffused without impairing the air direction adjusting function that should originally be performed.

[0038] <First Modified Example> In the air direction adjusting device 1 according to the above-described embodiment, the form of attaching to the ceiling-embedded air conditioner 101 was exemplified. However, the air direction adjusting device 1 may be attached to a wall-mounted air conditioner fixed to a wall surface. In this case, the air direction adjusting device 1 may be arranged in front of the air outlet of the wall-mounted air conditioner with the main body 2 supported by the support rod 3 or the base 4. However, the air direction adjusting device 1 may be modified as follows, for example.

[0039] FIG. 7 is a view showing the air direction adjusting device 1A according to the first modified example. The air direction adjusting device 1A according to this modified example has a form in which the support rod 3 and the base 4 are omitted from the air direction adjusting device 1 and only the main body 2 remains.

[0040] The wind direction adjustment device 1A can be attached inside the air conditioning outlet 202 of the wall-mounted air conditioner 201 fixed to the wall surface. For example, as shown in FIGS. 7(A) to 7(C), the wind direction adjustment device 1A is mounted inside the air conditioning outlet 202 after the louver 203 standardly equipped on the wall-mounted air conditioner 201 is removed from the inside of the air conditioning outlet 202 and replaces the louver 203. The louver 203 is normally rotatably fitted to a shaft for engagement provided inside the air conditioning outlet 202. This engagement shaft is normally fitted at three locations, i.e., both ends and the central portion of the louver 203, and one of the three shafts serves as a drive mechanism for electrically swinging. Therefore, by providing fitting holes corresponding to these three shafts also in the rod-shaped portion 22 of the wind direction adjustment device 1A, it can be attached inside the air conditioning outlet 202 in a form of replacing the louver 203 standardly equipped on the wall-mounted air conditioner 201. With the wind direction adjustment device 1A in such a form, it can be integrated with the wall-mounted air conditioner 201.

[0041] Even with such a wind direction adjustment device 1A, similar to the wind direction adjustment device 1, the disturbance of the air flow is suppressed as much as possible. Therefore, the active ingredient of the member 29 stored in the storage space 25 can be diffused without impairing the wind direction adjustment function that should originally be performed. In such a wind direction adjustment device 1A, an openable and closable access port for taking in and out the member 29 in the storage space 25 may be provided, for example, on the outer peripheral surface of the rod-shaped portion 22. If the access port is in such a location, it becomes easy to replace the member 29 in the storage space 25 even when the wind direction adjustment device 1A is in the air conditioning outlet 202.

[0042] Incidentally, the wind direction adjustment device 1A may be standard equipment for the wall-mounted air conditioner 201. Further, the wind direction adjustment device 1A may be attached to the air-conditioning outlet 102 of the ceiling-embedded air conditioner 101, or may be attached to the outlets of various other air conditioners. FIG. 8 is a diagram illustrating a form in which the wind direction adjustment device 1A according to the first modification is provided at the air-conditioning outlet 102 of the ceiling-embedded air conditioner 101. The wind direction adjustment device 1A can be provided at the air-conditioning outlet 102 of the ceiling-embedded air conditioner 101, for example, as shown in FIG. 8. In this case, the rod-shaped portion 22 of the wind direction adjustment device 1A is arranged inside the air-conditioning outlet 102, and the wind direction adjustment plate portion 21 is provided in a form that protrudes from the air-conditioning outlet 102.

[0043] <Second Modification> In the wind direction adjustment device 1 according to the above embodiment, the rod-shaped portion 22 was provided over the entire portion corresponding to one side of the long side of the rectangular wind direction adjustment plate portion 21. However, the wind direction adjustment device 1 may be modified as follows, for example.

[0044] FIG. 9 is a diagram showing the wind direction adjustment device 1B according to the second modification. In the wind direction adjustment device 1B according to this modification, the rod-shaped portion 22 is provided only at a part of the edge of the wind direction adjustment plate portion 21 on the side of the air-conditioning outlet 102. That is, the wind direction adjustment device 1B according to this modification has a form in which a part of the rod-shaped portion 22 according to the embodiment is omitted.

[0045] Even with such a wind direction adjustment device 1B, similar to the wind direction adjustment device 1 according to the embodiment, the disturbance of the air flow is suppressed as much as possible. Therefore, the active ingredient of the member 29 containing the active ingredient stored in the storage space 25 can be diffused without impairing the wind direction adjustment function that should originally be performed.

[0046] <Other Modifications> Furthermore, various further modifications may be made to the above-described embodiments and each modification example. In the above-described embodiments and each modification example, for example, the support rod 3 may be one or three or more. Also, the above-described embodiments and each modification example may be in a form attached to the air conditioner by means other than the base 4. Also, the above-described embodiments and each modification example may be attached to types of air conditioners other than the ceiling-embedded air conditioner 101 and the wall-mounted air conditioner 201. Also, in the above-described embodiments and each modification example, the form presented was such that the wind direction adjustment plate portion 21 was abutted against the rod-shaped portion 22. However, in the above-described embodiments and each modification example, for example, a gap may be provided between the rod-shaped portion 22 and the wind direction adjustment plate portion 21, and the rod-shaped portion 22 and the wind direction adjustment plate portion 21 may be spaced apart from each other. In this case, for example, the wind direction adjustment plate portion 21 may be fixed to the rod-shaped portion 22 via a support member or the like, or the main body 2 of an integrated product in which a slit extending along the longitudinal direction of the rod-shaped portion 22 is disposed between the wind direction adjustment plate portion 21 and the rod-shaped portion 22 may also be used.
