Description

The present invention relates to a blower such as an indoor unit of an air conditioner.

Generally, the indoor unit of an air conditioner is equipped with a cross-flow fan for blowing air. In order to efficiently blow air with the cross fan, it is necessary to make the air passage as long as possible. However, if the air passage is lengthened, the indoor unit itself becomes large, which is not preferable. Therefore, in a general indoor unit, in order to secure an air passage, an airflow panel (airflow panel) that can be opened and closed is provided at the outlet of the indoor unit body, and the airflow panel is opened at the time of blowing air. The airflow path is lengthened by the length of the airflow direction.

By the way, when the airflow panel is provided, a gap is provided between the airflow panel and the airflow outlet so as not to interfere with the airflow outlet when the airflow panel opens and closes. However, this gap is not a problem when the airflow panel is closed (when the airflow is stopped), but is a problem when the airflow panel is open (when the airflow is blown). That is, there arises a problem that the air leaks from the gap formed between the airflow panel and the air outlet at the time of blowing air.

Therefore, in order to fill the gap formed between the airflow panel and the air outlet, a sealing material is provided to prevent the wind from leaking from the gap at the time of blowing air. For example, there is an air conditioner described in Patent Document 1.

Japanese Patent Publication "Japanese Patent Laid-Open No. 2012-154559"

However, as in the air conditioner of Patent Document 1, when the seal members are arranged concentrically with respect to the rotation locus, if the wind direction adjusting plate (air flow panel) is warped, a gap may occur or the rotation may occur. It may interfere with the movement. Further, in order to prevent a gap from being generated even if the wind direction adjusting plate is warped, it is conceivable that the wind direction adjusting plate is strongly brought into contact with the seal member. In this case, the rotation operation of the wind direction adjusting plate is performed. There is a risk that the seal member will come off.

One aspect of the present invention is to realize a blower device capable of appropriately sealing between the wind direction adjusting plate and the air outlet at the time of blowing air, and the sealing member is not peeled off by the rotational operation of the wind direction adjusting plate. ..

In order to solve the above problems, the blower according to one aspect of the present invention opens and closes an air outlet that blows out air, and when opened, a wind direction adjusting plate that forms a part of the air passage of the wind that blows out from the air outlet is provided. The airflow adjusting plate is rotatably supported so that a gap is formed between the airflow direction adjusting plate and the airflow outlet so as not to interfere with the member forming the air outlet when the airflow direction is opened and closed. A sealing member for sealing the gap is provided between the wind direction adjusting plate and the air outlet at least when the wind direction adjusting plate is opened, and the thickness of the sealing member is equal to or greater than the thickness of the airflow panel. It is characterized by that.

According to one aspect of the present invention, it is possible to appropriately seal between the wind direction adjusting plate and the air outlet at the time of blowing air, and it is possible to obtain the effect that the sealing member is not peeled off by the rotational operation of the wind direction adjusting plate.

[Embodiment 1]
Hereinafter, Embodiment 1 of the present invention will be described in detail. In this embodiment, an example in which the blower device of the present invention is applied to an indoor unit of an air conditioner will be described. However, the blower according to one aspect of the present invention may be a ceiling-mounted air conditioner, a floor-standing air conditioner, or an indoor-only air conditioner that does not have an outdoor unit. It may be a window-mounted air conditioner, etc.). Further, the blower according to one aspect of the present invention is not limited to an air conditioner, and any blower such as a tower fan or an air purifier may be used.

Although various members of the indoor unit 1 are shown in the drawings described below (particularly FIGS. 2 to 5), the description of the members not related to the present embodiment will be omitted. It may be understood that the members for which these explanations are omitted are the same as those known. Also, it should be noted that each drawing is intended to schematically explain the shape, structure, and positional relationship of each member, and is not necessarily drawn according to the scale.

(Overview of indoor unit)
FIG. 1 is a perspective view showing the appearance of the indoor unit 1 in the front direction. As shown in FIG. 1, the indoor unit 1 includes an airflow panel 11 (wind direction adjusting plate) and a cabinet 12 (housing) as outer components. The airflow panel 11 is supported by the cabinet 12 so as to be openable and closable.

In FIG. 1, when the indoor unit 1 installed on the wall surface is viewed from the front (front), the ceiling side is the upper side, the floor side is the lower side, and the longitudinal direction of the indoor unit 1 is the left-right direction. Further, the direction from the back surface (back surface) of the indoor unit 1 to the front surface is referred to as a depth direction.

Hereinafter, the left-right direction is also referred to as an X direction, the depth direction is also referred to as a Y direction, and the up-down direction is also referred to as a Z direction. Here, the positive direction in the X direction is the right direction. Further, the positive direction in the Y direction is the forward direction. Further, the positive direction in the Z direction is the upward direction. In the present embodiment, the X direction, the Y direction, and the Z direction will be described as being orthogonal to each other.

The airflow panel 11 defines the flow path of the airflow blown into the room. The opening and closing of the airflow panel 11 is controlled by a control device (not shown) in the indoor unit 1 according to the operating state of the indoor unit 1. When the airflow panel 11 is opened, the air outlet as the flow path is exposed.

Further, the cabinet 12 may be provided with a light receiving unit (input unit) that receives light rays such as infrared rays emitted from a remote controller that receives an operation instruction from the user. Further, the cabinet 12 may be further provided with a notification unit (eg, a display unit, a lamp, a speaker) for notifying the user of various information.

(Details of indoor unit)
2 to 5 show a cross-sectional view taken along the line AA of the indoor unit 1 shown in FIG.

As shown in FIG. 2, the indoor unit 1 includes a heat exchanger 13 and a cross flow fan 14 inside the cabinet 12.

The heat exchanger 13 is provided above the inside of the cabinet 12 so as to surround the upper side of the cross flow fan 14, which will be described later. The heat exchanger 13 acts as an evaporator that vaporizes the refrigerant during the cooling operation, and takes heat from the air in the room. On the other hand, the heat exchanger 13 acts as a condenser that liquefies the refrigerant during the heating operation, and releases heat into the room.

The cross-flow fan 14 has a central axis parallel to the longitudinal direction (X direction) of the indoor unit 1 and can rotate around the central axis by the driving force of a motor (not shown). Further, the cross flow fan 14 is provided with a plurality of blades (not shown) for sucking and delivering air in the circumferential direction. By rotating the cross flow fan 14 around the central axis, indoor air is sucked from the air intake port, and an air flow blown out from the air flow panel 11 into the room is created. Specifically, the airflow passes through a path that sequentially follows the upper surface of the cabinet 12, which is an air intake port, the heat exchanger 13, the cross flow fan 14, and the airflow panel 11.

The airflow panel 11 opens and closes the airflow outlet 15 that blows out the airflow (wind) created by the indoor unit 1 into the room. It is designed to form a part of. As a result, it is possible to secure an air passage having a required length while maintaining the miniaturization of the indoor unit 1.

The airflow panel 11 is rotatably supported by a rotating shaft 16 so that a gap is formed between the airflow panel 11 and the air outlet 15 when the airflow panel 11 is opened and closed. Specifically, as shown in FIGS. 3 and 5, a gap A is formed between the end portion 11a of the airflow panel 11 in the rotation axis direction and the end portion of the air passage 15a on the air outlet 15 side. As a result, the airflow panel 11 does not interfere with the air outlet 15 when opening and closing. Further, the rotating shaft 16 is provided at a position slightly shifted toward the inside of the cabinet 12 from the extension line in the direction (Y direction) toward the air outlet 15 of the airflow panel 11. By shifting the rotating shaft 16 in this way, it is possible to change the size of the gap A formed between the airflow panel 11 and the airflow outlet 15 that is generated when the airflow panel 11 opens and closes. In the case of the present embodiment, the position of the rotating shaft 16 is determined so that the gap A formed between the airflow panel 11 and the airflow outlet 15 is larger when the airflow panel 11 is closed than when it is open. Has been done.

(Seal member)
A sealing member 17 for sealing the gap A is provided at the end of the air outlet 15 on the air passage 15a side. The seal member 17 is made of an elastic material such as a substantially rectangular parallelepiped heat insulating material extending in the longitudinal direction (X direction) of the outlet 15. The sealing member 17 is adhesively fixed to the adhesive surface 15b orthogonal to the air passage 15a of the cabinet 12. The material of the seal member 17 may be any material such as an elastic heat insulating material, and is not particularly limited.

The width H of the seal member 17 is defined as the length in the direction parallel to the air passage 15a. The width H is a state in which the airflow panel 11 is open (FIGS. 4 and 5), the end portions 11a of the airflow panel 11 can be brought into contact with each other with an appropriate pressure, and the airflow panel 11 is closed (FIGS. 2 and 3). ), The length is set so as not to come into contact with the end portion 11a of the airflow panel 11. That is, the sealing member 17 is formed so as to seal the gap A only when the airflow panel 11 is open. As a result, when the airflow panel 11 is open, the seal member 17 is pressed against the adhesive surface 15b by the airflow panel 11, so that the seal member 17 is less likely to be peeled off from the adhesive surface 15b. Moreover, since the airflow panel 11 does not always come into contact with the seal member 17 when opening and closing, there is no problem that the seal member 17 is peeled off as the airflow panel 11 opens and closes.

Further, the thickness D of the seal member 17 (the length in the direction orthogonal to the air passage 15a) is equal to or greater than the thickness of the airflow panel 11. As a result, even if the airflow panel 11 is bent and deformed (broken line portion in FIG. 5), the thickness of the seal member 17 is equal to or greater than the thickness of the airflow panel 11, so that when the airflow panel 11 comes into contact with the seal member 17, the seal member 17 is formed. The deformed portion of the airflow panel 11 can be absorbed by the seal member 17. As a result, even if the airflow panel 11 is slightly deformed, the gap A between the airflow panel 11 and the air outlet 15 can be reliably sealed.

The thickness D of the seal member 17 is preferably equal to the thickness of the airflow panel 11, but more preferably equal to or greater than the thickness of the airflow panel 11. The upper limit of this thickness is within a range that does not hinder the rotation of the airflow panel 11 and does not protrude outside the cabinet 12 of the indoor unit 1, and is appropriately determined depending on the size of the indoor unit 1. ..

(effect)
According to the indoor unit 1 having the above configuration, the gap A between the airflow panel 11 and the air outlet 15 is surely sealed by the sealing member 17 when the airflow is blown, that is, when the airflow panel 11 is open. Therefore, it is possible to prevent leakage of air (cold air in the case of cooling, warm air in the case of heating) from the gap A. As a result, it is possible to suppress performance deterioration due to wind leakage. For example, in the case of cooling, dew condensation caused by leakage of cold air can be eliminated, so that deterioration of cooling performance can be suppressed. In particular, in the case where the indoor unit 1 is provided on the upper side near the ceiling of the room in order to efficiently circulate the blown air in the room, the air outlet 15 of the indoor unit 1 is provided on the lower side of the indoor unit 1. It is effective when it is.

Further, according to the indoor unit 1 having the above configuration, the seal member 17 can reliably absorb the deformation of the airflow panel 11 such as the warp, so that the gap A can be reliably maintained even when the airflow panel 11 is long in the longitudinal direction. It becomes possible to seal. In this case, it is particularly effective for the airflow panel 11 used when the length (width) of the outlet 15 in the longitudinal direction is long in order to blow out the airflow from the fan long in the longitudinal direction, such as the cross flow fan 14. That is, the width of the air outlet 15 is particularly effective when it is as long as the length in the longitudinal direction of the blower fan that produces the blown air (or more than a predetermined length).

In the blower device of the present invention, the fan that generates the airflow is not limited to the cross flow fan 14, and may be a fan having a wide outlet 15 such as a propeller fan or a sirocco fan.

Further, when the air outlet 15 of the indoor unit 1 is provided on the lower side of the indoor unit 1 as in the present embodiment, in order to surely seal the airflow leakage, the airflow panel 11 is inevitably provided. Is preferably provided below the air outlet 15. However, the position where the airflow panel 11 is provided is not limited to this. For example, when the airflow port 15 of the indoor unit 1 is provided above the indoor unit 1, the airflow panel 11 is also provided at the airflow port 15. It is preferable to provide it on the upper side.

In the following embodiments 2 and 3, various examples of how to provide the seal member will be described.

[Embodiment 2]
Other embodiments of the present invention will be described below. For convenience of explanation, the members having the same functions as the members described in the above-described embodiment are designated by the same reference numerals, and the description thereof will not be repeated.

In the present embodiment, various examples of how to provide the seal member 17 (rectangular parallelepiped) for sealing the gap A between the airflow panel 11 and the air outlet 15 in the indoor unit 1 of the first embodiment will be described in FIG. 6 (a). )-(C) will be described. In the figure, the broken line indicates the state in which the airflow panel 11 is warped.

FIG. 6A is a diagram schematically showing the indoor unit 1 shown in FIG. 4, and is a diagram in which a wall is provided on the air passage 15a side of the adhesive surface 15b of the sealing member 17. This wall has substantially the same length as the width H of the seal member 17. As a result, even if the airflow panel 11 rotates about the rotation shaft 16 in the direction of the arrow, the wall can prevent the seal member 17 from peeling off.

FIG. 6B is a diagram showing a state in which the wall is shorter than that of FIG. 6A. In this case, since the air passage 15a side is opened, the width of the seal member 17 can be easily adjusted.

FIG. 6 (c) is a diagram showing a state in which the wall is thinner than that of FIG. 6 (b). In this case, the air passage 15a side is further opened.

Up to this point, an example using a substantially rectangular parallelepiped seal member 17 has been shown, but in the following embodiment 3, another example of the shape of the seal member 17 will be described.

[Embodiment 3]
Other embodiments of the present invention will be described below. For convenience of explanation, the members having the same functions as the members described in the above-described embodiment are designated by the same reference numerals, and the description thereof will not be repeated.

In the present embodiment, an example of a sealing member having a shape other than the sealing member 17 (rectangular parallelepiped) that seals the gap A between the airflow panel 11 and the air outlet 15 in the indoor unit 1 of the first embodiment is shown in FIG. d) This will be described with reference to (f). In the figure, the broken line indicates the state in which the airflow panel 11 is warped.

FIG. 6D shows an example in which the adhesive surfaces 15b of FIGS. 6A to 6C are curved surfaces having a predetermined curvature. In this case, since the seal member 18 is attached along the curved surface, the seal member 18 also has a curved surface. Since the surface of the seal member 18 that comes into contact with the end portion 11a of the airflow panel 11 is recessed, the warp of the airflow panel 11 can be easily absorbed, and as a result, the sealing effect of the seal member 18 can be enhanced.

In FIG. 6 (e), as shown in FIG. 6 (d), instead of having the adhesive surface 15b have a curved surface, a recess is formed in two planes, and two so as to correspond to the respective planes. An example in which the sealing members 19 and 19 are adhered is shown. In this case as well, as in (d) of FIG. 6, since the surface of the airflow panel 11 in contact with the end portion 11a is recessed, the warp of the airflow panel 11 is easily absorbed, and as a result, the seal member 18 seals. The effect can be enhanced.

The seal members 17, 18 and 19 of FIGS. 6A to 6E are provided only on the air passage 15a side. However, the present invention is not limited to this, and for example, as shown in FIG. 6 (f), the sealing member is not only on the adhesive surface 15b side of the air passage 15a but also on the end portion 11a of the airflow panel 11. 20 may be provided. In this case, if the gap A is the same, the width H of the seal member 19 provided on the air passage 15a side can be shortened, so that the seal member 19 is less likely to be peeled off from the adhesive surface 15b.

In the first to third embodiments, an example has been described in which the sealing members 17 to 19 and the airflow panel 11 do not abut, that is, the gap A is not sealed when the airflow panel 11 is closed. However, the sealing members 17 to 19 may seal the gap A not only when the airflow panel 11 is opened but also when the airflow panel 11 is closed.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims, and the embodiments obtained by appropriately combining the technical means disclosed in the different embodiments. Is also included in the technical scope of the present invention. Furthermore, new technical features can be formed by combining the technical means disclosed in each embodiment.
