Description

  The present invention relates to an indoor unit of an air conditioner.

  2. Description of the Related Art In general, indoor units of air conditioners have a structure in which driving units provided on the left and right sides of an air outlet and columns provided near a center of the air outlet support a vertical plate. In the indoor unit, the size of the upper and lower wind direction plates tends to be increased in order to improve the wind direction performance. In the indoor unit, the weight of the upper and lower wind direction plates increases with the size of the upper and lower wind direction plates, and the torque of the drive unit that drives the upper and lower wind direction plates also increases.

  In such an indoor unit, due to an increase in the weight of the upper and lower wind direction plates and an increase in the torque of the driving section, a relatively large load supports the upper and lower wind direction plates (specifically, the drive units provided on the left and right sides of the air outlet). Near the center and near the center of the air outlet). If an unintended load is applied to the upper and lower wind direction plates, a portion for mounting the upper and lower wind direction plates on the housing and a portion for supporting the upper and lower wind direction plates (particularly, the left or right Nearby) may be damaged. In addition, when the indoor unit of an air conditioner for general household is installed in an unexpected use environment, or when the indoor unit is exposed to an unintended chemical attack, There is a possibility that the mounting part of the above or the part supporting the upper and lower wind direction plates on the housing side (particularly, the vicinity of one of the left and right driving parts among them) may be damaged.

  If the vicinity of one of the left and right drive units is damaged, the indoor unit may move in the left-right direction and fall. Therefore, some indoor units of the air conditioner are provided with a mechanism for preventing a vertical wind direction plate from falling (see Patent Document 1). Patent Literature 1 discloses a structure in which when a shaft of a vane (a vertical wind direction plate) on the side receiving a rotational force is broken, a stopper component attached to a shaft tip of the other shaft is hooked on a bearing portion. An indoor unit of an air conditioner is described.

  However, the conventional indoor unit of an air conditioner described in Patent Literature 1, for example, has an increased number of components and a complicated structure, so that the workability of attaching and detaching components is poor. Such a conventional air conditioner indoor unit imposes a burden on an operator when assembling a product or installing the product in an installation place, and prolongs the working time. Also, the manufacturing cost is increased by the increased number of parts.

  The present invention has been made to solve the above-described problem, and has as its main object to provide an indoor unit of an air conditioner that has a simple configuration and prevents a vertical wind direction plate from falling or the like.

In order to achieve the above object, the present invention relates to an indoor unit of an air conditioner, which is a heat exchanger that exchanges heat between air and a refrigerant passing therethrough, a blower fan that sends air, and an air blower.

[Embodiment]
<Overall configuration of air conditioner>
Hereinafter, an overall configuration of an air conditioner 100 according to the present embodiment will be described with reference to FIG. FIG. 1 is an explanatory diagram of the overall configuration of an air conditioner 100 according to the present embodiment.

  As shown in FIG. 1, the air conditioner 100 according to the present embodiment includes an outdoor unit Uo and an indoor unit Ui, and the outdoor unit Uo and the indoor unit Ui constitute a refrigerant circuit Q. The solid line arrows in FIG. 1 indicate the flow of the refrigerant during the heating operation. The broken arrows in FIG. 1 indicate the flow of the refrigerant during the cooling operation.

  As shown in FIG. 1, the air conditioner 100 includes a compressor 11, an outdoor heat exchanger 12, an outdoor fan 13, an expansion valve 14, an indoor heat exchanger 15, and an indoor fan 16 (blowing fan). , A four-way valve 17.

The compressor 11 is a device that compresses a low-temperature and low-pressure gas refrigerant by driving a compressor motor 11a and discharges it as a high-temperature and high-pressure gas refrigerant.
The outdoor heat exchanger 12 includes a heat transfer tube (not shown) through which the refrigerant flows, and is a heat exchanger in which heat exchange is performed between the refrigerant flowing through the heat transfer tube and the outside air sent from the outdoor fan 13. is there.

The outdoor fan 13 is a fan that sends outside air to the outdoor heat exchanger 12 by driving the outdoor fan motor 13a, and is installed near the outdoor heat exchanger 12.
The expansion valve 14 is a valve that reduces the pressure of the refrigerant condensed in the “condenser” (one of the outdoor heat exchanger 12 and the indoor heat exchanger 15). The refrigerant decompressed by the expansion valve 14 is guided to an “evaporator” (the other of the outdoor heat exchanger 12 and the indoor heat exchanger 15).

The indoor heat exchanger 15 includes a heat transfer tube (not shown) through which the refrigerant flows, and the refrigerant flowing through the heat transfer tube and the indoor air (air in the space to be air-conditioned) sent from the indoor fan 16 (blowing fan). Is a heat exchanger in which heat exchange is performed.
The indoor fan 16 is a fan that sends indoor air to the indoor heat exchanger 15 by driving an indoor fan motor (not shown), and is installed near the indoor heat exchanger 15. More specifically, in the flow of air when the indoor fan 16 is rotating forward, the indoor fan 16 is installed downstream of the indoor heat exchanger 15.

  The four-way valve 17 is a valve that switches the flow path of the refrigerant in accordance with the operation mode of the air conditioner 100. For example, during the cooling operation (see the broken arrow in FIG. 1), the compressor 11, the outdoor heat exchanger 12 (condenser), the expansion valve 14, and the indoor heat exchanger 15 (evaporator) are connected to the four-way valve 17 The refrigerant circulates in the refrigeration cycle in the refrigerant circuit Q which is sequentially connected in a ring through the refrigeration cycle.

  On the other hand, during the heating operation (see the solid arrow in FIG. 1), the compressor 11, the indoor heat exchanger 15 (condenser), the expansion valve 14, and the outdoor heat exchanger 12 (evaporator) are operated by the four-way valve 17 The refrigerant circulates in the refrigeration cycle in the refrigerant circuit Q which is sequentially connected in a ring through the refrigeration cycle.

  In the example shown in FIG. 1, the compressor 11, the outdoor heat exchanger 12, the outdoor fan 13, the expansion valve 14, and the four-way valve 17 are installed in the outdoor unit Uo. On the other hand, the indoor heat exchanger 15 and the indoor fan 16 are installed in the indoor unit Ui.

  The housing of the indoor unit Ui is provided with an air inlet (not shown) and an air outlet OP. The indoor unit Ui takes in air from the room through an air inlet (not shown), air-conditions the taken-in air, and blows out the room from the air outlet OP. The indoor unit Ui is provided with a vertical wind direction plate 23 at the air outlet OP. The vertical wind direction plate 23 is a plate-like member that adjusts the vertical flow of air blown into the room as the indoor fan 16 rotates. In the present embodiment, the indoor unit Ui includes a driving unit 34 and a driving unit 35 (see FIG. 6A) provided on the left and right sides of the air outlet OP and a support 21 provided near the center of the air outlet OP (see FIG. 6A). ) Will be described as supporting the vertical wind direction plate 23.

<Rib as a means to prevent the vertical wind direction plate from falling>
By the way, in the indoor unit Ui, as the size of the vertical wind direction plate 23 increases, a relatively large load supports the vertical wind direction plate 23 (specifically, the vicinity of the driving units 34 and 35 (see FIG. 6A) and the support). 21 (around FIG. 2A). Then, when an unintended load is applied to the vertical wind direction plate 23, a portion for mounting the vertical wind direction plate 23 on the housing side and a portion supporting the vertical wind direction plate 23 on the housing side (particularly, the driving unit 34 or the driving unit 35). (See FIG. 6A) may be damaged. Further, when the indoor unit Ui of the air conditioner 100 for general household is installed in an unexpected use environment, or when the indoor unit Ui is exposed to an unintended chemical attack, the vertical wind direction plate 23 may be used. There is a possibility that a portion attached to the housing on the side or a portion supporting the vertical wind direction plate 23 on the housing side (particularly, the vicinity of the driving unit 34 or the driving unit 35 (see FIG. 6A)) may be damaged.

  If the vicinity of the drive unit 34 or the drive unit 35 (see FIG. 6A) is damaged, the vertical wind direction plate 23 tends to move in the left-right direction (the longitudinal direction of the indoor unit Ui). And if the structure which restricts the horizontal movement of the vertical wind direction board 23 is not provided in the indoor unit Ui, the vertical wind direction board 23 may fall.

  Therefore, the indoor unit Ui of the air conditioner 100 according to the present embodiment includes a rib on the mounting member 25 (see FIG. 4A) constituting the lower part of the decorative frame (exterior frame) as a means for preventing the vertical direction plate 23 from falling. 25a. Hereinafter, the structure related to the rib 25a will be described in detail.

  First, with reference to FIGS. 2A and 2B, the structure of the housing frame 20 to which the upper and lower wind direction plates 23 are attached will be described.

The column 21 is arranged along the direction of air flow through the air outlet OP (that is, so that both plate-shaped surfaces are parallel to the direction of air flow through the air outlet OP). The support 21 is provided with an engagement portion 21a. The engagement portion 21a is a circular hole that engages with a projection 24a (see FIG. 3B) provided on a support post 24 of the vertical wind direction plate 23 described later.

  In the example shown in FIG. 2B, the housing frame 20 includes a fastening portion 21b near the support 21. The fastening portion 21b is a portion that is fastened to the fastening portion 25b (see FIG. 4B) of the mounting member 25 by a screw (not shown).

  Next, with reference to FIGS. 3A and 3B, the structure of the vertical wind direction plate 23 will be described. FIG. 3A is an external view of the vertical wind direction plate 23 of the indoor unit Ui. FIG. 3B is an enlarged view of a region A12 in FIG. 3A.

  As shown in FIG. 3A, the vertical wind direction plate 23 has a plate shape that is long in the left-right direction. The vertical wind direction plate 23 includes a support 124 and a support 125 at the left end and the right end of the upper surface, and further includes a support 24 near the center of the upper surface. The strut 124 is a plate-like portion that is attached to the left driving unit 34 (see FIG. 2A) provided on the housing frame 20. The support 125 is a plate-like portion that is attached to the right driving unit 35 (see FIG. 2A) provided on the housing frame 20. The support 24 is a plate-like portion attached to a support 21 (see FIG. 2A) provided on the housing frame 20.

  In the example shown in FIG. 3A, the columns 124, the columns 125, and the columns 24 are each formed in an arc shape having substantially the same size in a side view. The support 124 has a protrusion 124a protruding leftward at the distal end thereof. The support 125 has a protrusion 125a protruding rightward at the distal end thereof. The support column 24 has a columnar protrusion 24a (see FIG. 3B) protruding leftward at the distal end.

  The protrusion 124a is inserted into and engaged with the drive unit 34 (see FIG. 2A) provided on the housing frame 20. In addition, the protrusion 125a is inserted into and engaged with the drive unit 35 (see FIG. 2A) provided on the housing frame 20. The upper and lower wind direction plates 23 are engaged with the driving portions 34 and 35 provided on the housing frame 20 by the protrusions 124 a and the protrusions 125 a provided so as to protrude in opposite directions. The part is attached to the housing frame 20.

  The protruding portion 24a is inserted into and engaged with an engaging portion 21a (see FIG. 2B) of a column 21 provided near the center of the housing frame 20. The upper and lower wind direction plates 23 are attached to the housing frame 20 in the vicinity of the center by the projections 24 a engaging with the engagement portions 21 a (see FIG. 2B) of the columns 21.

  Next, the structure of the mounting member 25 will be described with reference to FIGS. 4A and 4B. The attachment member 25 is a member that constitutes a lower portion of the decorative frame (exterior frame) of the indoor unit Ui. FIG. 4A is an external view of the mounting member 25 of the indoor unit Ui. FIG. 4B is an enlarged view of a region A13 in FIG. 4A.

  As shown in FIG. 4A, the mounting member 25 has a plate shape that is long in the left-right direction. The mounting member 25 has a rib 25a near the center of the upper surface. The rib 25a is a part that restricts the horizontal movement of the vertical wind direction plate 23. As shown in FIG. 4B, in the present embodiment, the rib 25a has a triangular shape. The rib 25a is provided at a position facing a surface opposite to the surface on which the protrusion 24a is provided with respect to the support 24 of the vertical wind direction plate 23 (see FIG. 6B). The support columns 24 of the vertical wind direction plate 23, the projections 24a and the ribs 25a provided on the support columns 24 are provided at positions that are not visible from the outside when the vertical wind direction plate 23 is closed.

  In the example illustrated in FIG. 4B, the attachment member 25 includes a fastening portion 25 b at a position overlapping the fastening portion 21 b of the housing frame 20. The fastening portion 25b is a portion that is fastened to the fastening portion 21b (see FIG. 2B) of the housing frame 20 by a screw (not shown).

  As shown in FIG. 5A and FIG. 5B, the vertical wind direction plate 23 is attached to the housing frame 20. FIG. 5A is a diagram illustrating a state in which the upper and lower wind direction plates 23 are attached to the housing frame 20. FIG. 5B is an enlarged view of the area A14 in FIG. 5A.

  At this time, the protrusion 124 a of the support column 124 of the vertical wind direction plate 23 engages with the left drive unit 34 provided on the housing frame 20. In addition, the projection 24 a of the column 24 of the vertical wind direction plate 23 is engaged with the engagement portion 21 a of the column 21 of the housing frame 20. The protrusion 125 a of the support 125 of the vertical wind direction plate 23 engages with the right drive unit 35 provided on the housing frame 20. In addition, a gap 45 is opened between the housing frame 20 and the vertical wind direction plate 23.

  As shown in FIG. 6A and FIG. 6B, the mounting member 25 is mounted between the housing frame 20 and the vertical wind direction plate 23 so as to close the gap 45 (see FIG. 5A). FIG. 6A is a diagram illustrating a state where the attachment member 25 is attached to the housing frame 20. FIG. 6B is an enlarged view of the area A15 in FIG. 6A.

  At this time, as shown in FIG. 6B, the rib 25a of the mounting member 25 is disposed at a position facing the support 24 of the vertical wind direction plate 23 on the surface opposite to the surface on which the projection 24a is provided. Is done. The fastening portion 25b of the mounting member 25 is fastened to the fastening portion 21b (see FIG. 2B) of the housing frame 20 with screws (not shown). Thereby, the mounting member 25 is fixed to the housing frame 20. Thereafter, the sealing member 26 is attached to the fastening portion 25b. The sealing member 26 is a member that closes the fastening portion 25b.

<Position relation between the support of the vertical wind direction plate and the rib of the mounting member>
Hereinafter, the positional relationship between the support columns 24 of the upper and lower wind direction plates 23 and the ribs 25a of the mounting member 25 will be described with reference to FIGS. 7A and 7B. FIG. 7A is a perspective view showing the entire configuration of the support column 24 of the vertical wind direction plate 23 and the rib 25a of the mounting member 25. FIG. 7B is an explanatory diagram of the positional relationship between the support column 24 of the vertical wind direction plate 23 and the rib 25a of the mounting member 25. FIG. 7B is a layout in which a cross section, that is, a cross section obtained by cutting the support column 24 of the vertical wind direction plate 23 and the rib 25a of the mounting member 25 shown in FIG. Is shown.

  As shown in FIGS. 7A and 7B, the projections 24 a of the columns 24 of the vertical wind direction plate 23 are inserted into the engagement portions 21 a of the columns 21 of the housing frame 20.

  As shown in FIG. 7B, the rib 25a preferably satisfies the relationship of “t2> t1> 0” with the support 24 of the vertical wind direction plate 23. Here, "t1" represents a gap amount between the support column 24 of the vertical wind direction plate 23 and the rib 25a. Further, “t2” represents a margin between the engaging portion 21a of the column 21 of the housing frame 20 and the projecting portion 24a of the column 24 of the vertical wind direction plate 23 (the insertion amount of the projecting portion 24a into the engaging portion 21a). ing. In such an indoor unit Ui, the movement of the vertical wind direction plate 23 in the left-right direction is reliably restricted by the rib 25a, and the vertical wind direction plate 23 can be prevented from falling.

  Further, it is more preferable that the rib 25a satisfies the relationship of “t2> t1 × 2” with the support column 24 of the vertical wind direction plate 23. In such an indoor unit Ui, it is possible to make it difficult for the protrusion 24 a of the support 24 of the vertical wind direction plate 23 to come off from the engagement portion 21 a of the support 21 of the housing frame 20. Therefore, the indoor unit Ui can more efficiently prevent the vertical wind direction plate 23 from falling.

  8A and 8B, the mounting member 25 preferably has a flat inclined surface and a flat lower surface, and the inclined surface and the lower surface form an acute L-shape in a side view. It is good to have a shape. The rib 25a preferably has a triangular shape in a side view. FIG. 8A is a perspective view of the mounting member 25. FIG. 8B is a side view of the mounting member 25.

  In such a mounting member 25, the lower surface of the mounting member 25 and the upper surface of the rib 25a can be arranged in a substantially parallel positional relationship. Thereby, the rib 25a can be prevented from protruding upward from the upper end of the mounting member 25. Such an attachment member 25 can be easily extracted from a mold when manufactured by injection molding. Therefore, manufacture is easy.

<Main features of indoor units of air conditioners>
(1) As shown in FIG. 6A, the indoor unit Ui of the air conditioner 100 according to the present embodiment includes a housing frame 20, a vertical wind direction plate 23, and a mounting member 25. As shown in FIG. 6B, the housing frame 20 has an engaging portion 21a that engages with the vertical wind direction plate 23. The vertical wind direction plate 23 has a support column 24 provided with a protrusion 24 a that engages with the engagement portion 21 a of the housing frame 20. The mounting member 25 has a rib 25a at a position facing a surface opposite to the surface on which the protruding portion 24a is provided with respect to the column 24 of the vertical wind direction plate 23.

  Such an indoor unit Ui of the air conditioner 100 according to the present embodiment has the lower side of the decorative frame (exterior frame) even if the vicinity of the drive unit 34 or the drive unit 35 (see FIG. 6A) is damaged. The rib 25a of the mounting member 25 constituting a part abuts on the support 24 of the vertical wind direction plate 23. Thereby, the indoor unit Ui can restrict the movement of the vertical wind direction plate 23 in the left-right direction. For this reason, the indoor unit Ui can prevent the vertical wind direction plate 23 from falling or the like with a simple configuration.

  In the configuration in which the rib 25a is not provided, the principle that the vertical wind direction plate 23 moves in the left-right direction when the drive unit 34 or the vicinity of the drive unit 35 is damaged is as follows. For example, as shown in FIG. 6A, the vertical wind direction plate 23 is engaged with the housing frame 20 by the protrusion 124 a of the right support 124, the protrusion 24 a of the support 24 near the center, and the protrusion 125 a of the left support 125. doing. The right projection 124a and the projection 24a near the center project in the same direction, while the left projection 125a projects in the opposite direction. The housing frame 20 restricts the vertical wind direction plate 23 from moving to the right in a portion around the protrusion 124a and a portion around the protrusion 24a. Further, the housing frame 20 restricts the vertical wind direction plate 23 from moving leftward at a portion around the projection 125a. Here, it is assumed that a portion around the left protrusion 125a (that is, the vicinity of the driving unit 35) is damaged. In this case, the housing frame 20 cannot restrict the movement of the vertical wind direction plate 23 to the left. Therefore, the up-down direction board 23 tends to move to the left. In the configuration in which the rib 25a is not provided, the principle that the vertical wind direction plate 23 moves in the left-right direction is as described above.

  (2) As shown in FIG. 6A, the vertical wind direction plate 23 may include three or more columns (in the example shown in FIG. 6A, three columns 124, columns 24, and columns 125). The rib 25a may be provided at least at a position corresponding to a column (the column 24 in the example shown in FIG. 6A) near the middle of the vertical wind direction plate 23.

  Since the support 124 and the support 125 provided at the end of the vertical wind direction plate 23 are close to the drive unit 34 or the drive unit 35, a relatively large load is applied. On the other hand, the strut 24 near the center of the vertical wind direction plate 23 is apart from the driving unit 34 and the driving unit 35, and therefore, applies a smaller load than the strut 124 and the strut 125. Therefore, the support 24 is less likely to be damaged than the other support 124 and the support 125. In the indoor unit Ui of the air conditioner 100 according to the present embodiment, the rib 25a corresponds to the support post 24 near the middle, which is hard to break, so that the movement of the vertical wind direction plate 23 can be restricted efficiently.

  (3) As shown in FIG. 7B, the rib 25a preferably satisfies the relationship of “t2> t1> 0” with respect to the support column 24 of the vertical wind direction plate 23. Further, it is more preferable that the rib 25a satisfies the relationship of “t2> t1 × 2” with the support column 24 of the vertical wind direction plate 23.

  In the indoor unit Ui of the air conditioner 100 according to the present embodiment as described above, the horizontal movement of the vertical wind direction plate 23 is reliably restricted by the rib 25a, and the vertical wind direction plate 23 can be prevented from falling. .

  (4) As shown in FIG. 6A, the rib 25a is preferably provided along the direction in which air passes through the air outlet OP.

  Such an indoor unit Ui of the air conditioner 100 according to the present embodiment can maintain the wind direction performance because the rib 25a does not hinder the flow of air.

  As described above, according to the indoor unit Ui of the air conditioner 100 according to the present embodiment, it is possible to prevent the upper and lower wind direction boards from falling, etc., with a simple configuration.

The present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the gist of the present invention.
For example, the above-described embodiment has been described in detail for easy understanding of the gist of the present invention. Therefore, the present invention is not necessarily limited to the one including all the described components. Further, the present invention can add another component to a certain component, or change some components to another component. Further, the present invention can also eliminate some components.

  Further, for example, in the above-described embodiment, the rib 25 a is provided near the center of the upper surface of the mounting member 25 so as to correspond to the column 24 of the vertical wind direction plate 23. However, the ribs 25a may be provided not only near the center of the upper surface of the mounting member 25 but also near the left end and the right end so as to correspond to the columns 124 and the columns 125 of the vertical wind direction plate 23.
