DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an air conditioner, and more particularly to an improvement in an indoor unit.

[0002]

2. Description of the Related Art In an air conditioner indoor unit, a blower fan and a heat exchanger are provided inside a casing, and the blower fan is driven to generate an airflow from a suction port to a blower port. The heat exchanger includes a heat transfer tube through which a refrigerant circulates and fins for facilitating heat transfer, and is disposed in an air flow generated by a blower fan. For this reason, the air sucked in from the suction port is cooled or heated while passing through the heat exchanger, and is discharged from the blowing port.

[0003] In general, there are many indoor units in which a front panel and an upper panel are formed in a lattice shape, and the lattice portion is used as a suction port. In this case, an air filter is attached to the inside of the lattice portion of the front panel and the top panel so as to prevent dust in the air from entering the inside of the air conditioner. When such a grid-like panel is used, there is a problem that it takes time to manufacture a mold and it is difficult to remove dust and dirt attached to the grid portion. In particular, when the front panel is formed in a grid shape, the air filter can be seen from the front through the grid portion, which may impair the aesthetic appearance.

In order to cope with such a problem, it is conceivable that the front panel is formed of a plurality of flat-shaped flaps, and when stopped, the flaps are closed to give a flat appearance as a whole. In this case, as compared with the case of using the lattice-shaped panel, the mold can be easily manufactured, the cost can be reduced, and the dust and dirt attached can be easily removed because the uneven shape is reduced. Becomes Further, when the operation is stopped, the air filter and the internal components are not seen from the front because each flap is closed.

[0005]

In the indoor unit of the air conditioner provided with the front panel as described above, each flap is opened to open the suction port during operation. For this reason, the design of the indoor unit differs between when the operation is stopped and when the operation is performed, and in some cases, the air filter and the internal components located inside may be externally viewed from the front and the appearance may be impaired during the operation. In addition, an actuator for operating each flap is required, which makes it difficult to reduce costs.

SUMMARY OF THE INVENTION An object of the present invention is to provide an air conditioner capable of sucking room air from the front surface, having no change in design at the time of operation and at the time of stopping, and being constructed at a low cost.

[0007]

An air conditioner according to the present invention includes a front panel main body and a shielding panel. The front panel main body includes a blower fan and a heat exchanger therein, and has an indoor unit casing body mounted indoors, and is mounted on a front side of the indoor unit casing main body, and is located at least in front of the heat exchanger and has a front opening. Part. The shielding panel substantially overlaps with the front opening in a front view, and the outer surface is disposed on a curved surface that extends the outer surface excluding the front opening of the front panel main body, and between the front panel main body and the front and rear direction. It is arranged to have a gap. Then, room air is sucked from a gap between the front panel main body and the shielding panel, and the sucked room air is introduced into the heat exchanger through the front opening.

[0008] Thus, the room air can be sucked through the gap between the front panel main body and the shielding panel, and both the front panel main body and the shielding panel do not move, so that the room air does not move between the operation and the stop. Changes in design can be eliminated. In addition, since there are no movable parts on the front panel, there is no need to provide an actuator or the like, and cost can be reduced. Further, since the shielding panel is provided so as to substantially overlap with the front opening in the front view, the air filter and the internal components are not seen from the front, and the appearance is not spoiled.

In addition, a blower fan and a heat exchanger are installed,
An indoor unit casing main body attached to the room, a front panel main body attached to the front side of the indoor unit casing main body and having a front opening located at least in front of the heat exchanger, and at least a part of the front panel main body is attached to the front opening. Opposing, the outer surface is disposed on a curved surface extending the outer surface except the front opening of the front panel body, and a shielding panel disposed so as to provide a gap in the front-rear direction between the front panel body and the front panel body. The air conditioner may be configured to suck indoor air from a gap between the front panel main body and the shielding panel, and to introduce the sucked indoor air to the heat exchanger through the front opening.

Also in this case, since at least a part of the shielding panel is provided to face the front opening, the front opening is not exposed to the front, so that the design is not impaired. Here, the gap between the front panel body and the shielding panel includes an upper suction port located near the upper edge of the front opening, a lower suction port located near the lower edge of the front opening, or both. A configuration is possible.

Further, the shielding panel can be formed integrally with the front panel main body, can be formed of a separate member from the front panel main body, and can be fixed to the front panel main body.

Inside the casing body 2, a heat exchanger 17 is further arranged in the air flow generated by the cross flow fan 16. The heat exchanger 17 includes fins arranged at predetermined intervals, and heat transfer tubes inserted through the fins and sequentially connected at both ends of the fins in the arrangement direction to form a refrigerant path. The air is cooled or heated by contacting and exchanging heat with the contacted air with the generated air flow. The heat exchanger 17 has a configuration in which a front heat exchanger 17A and a rear heat exchanger 17B are combined in an inverted V shape. The front-side heat exchanger 17A and the rear-side heat exchanger 17
A cross flow fan 16 is disposed between the fan and the cross flow fan B.

The casing body 2 includes a front-side heat exchanger 1
A drain pan 18 for receiving condensed water generated in the front-side heat exchanger 17A is provided below the lower end of 7A. Similarly, a drain pan 19 for receiving condensed water generated in the rear heat exchanger 17B is provided in the casing body 2 below the lower end of the rear heat exchanger 17B.

The front frame 12 of the casing body 2
Constitutes a filter mounting frame 20 from the upper surface to the front surface, so that the air filter 21 can be mounted. The front panel 3 is further attached to the front of the front frame 12. This front panel 3
Front panel body 2 attached to casing body 2 side
2 and a shielding panel 23 disposed in front of the front panel main body 22.

At the upper end of the front panel main body 22, FIG.
A support member 24 as shown in FIG. 4 is fixed. The support member 24 has a support pin 25 protruding laterally, and is configured to be rotatably supported by the front frame 12. Hook portions 26 and 27 that engage with a part of the front side frame 12 are provided at a lower portion of the front panel main body 22.
Is provided. This allows the front panel body 2
2 is rotatable about a support pin 25.
By rotating clockwise, the front surface of the air filter 21 can be opened and the hook 2
The front panel main body 22, which can be brought into a closed state by engaging the front and rear frames 6, 27 with the front frame 12,
The front opening 28 is located in front of the front heat exchanger 17A.
Is provided. A shielding panel 23 is provided in front of the front opening 28 and substantially overlaps with the front opening 28 in a front view.

The shielding panel 23 is joined to the front panel main body 22 at the lower part, and is arranged at a predetermined distance from the front opening 28 in front of the panel. A front-back gap is provided between the front panel main body 22 and the shielding panel 23 in the front-rear direction from the vicinity of the upper edge of the front opening 28 to the side edge, and the gap is used to suction indoor air from the front. The mouth 29 is constituted.

The shielding panel 23 can be manufactured by integral molding of a synthetic resin together with the front panel main body 22, and is formed separately from the front panel main body 22 and fixed to the front panel main body 22 by welding or bonding. It is also possible. In the case of such a configuration, by driving the cross flow fan 16, the room air is sucked from the upper surface suction port 13 and the front surface suction port 29, and the air is introduced to the heat exchanger 17 side. In particular, on the front side of the indoor unit 1,
Since room air can be suctioned from the front suction port 29 formed between the front panel main body 22 and the shielding panel 23,
Room air can be sufficiently introduced from the front side. Moreover,
The front surface of the front opening 28 is almost covered by the shielding panel 23, so that the air filter 21 mounted on the front frame 12 is almost invisible. For this reason, the design of the indoor unit 1 from the front is not impaired. Further, since there are no movable parts on the front panel 3, an extra mechanism such as an actuator can be omitted, and there is no change in the design during operation and during stoppage.

[Air filter] When the front panel main body 22 and the shielding panel 23 are formed by integral molding of resin,
Considering removal of the mold, it is difficult to adopt a configuration in which the shielding panel 23 completely overlaps the front opening 28 in a front view. For this reason, as shown in FIG. 5, the shielding panel 23 is smaller than the front opening 28 at the front suction port 29, and an upper gap 35 and a side gap 36 are formed when viewed from the front. In this case, a part of the air filter 21 located behind the shielding panel 23 is seen from the front via the upper gap 35 and the side gap 36. In particular, when the dust-absorbing net portion of the air filter 21 is seen from the front side, the appearance is significantly impaired. For this reason, the front suction port 29
Is formed as a frame portion of the air filter 21, and a predetermined design is applied to this portion.

The air filter 21 is, for example, shown in FIG.
As shown in (1), it is composed of a filter frame 31 and a net portion 32 stretched over the filter frame 31. Here, when the air filter 21 is mounted on the filter mounting frame 20 of the front side frame 12, the upper half of the air filter 21 forms an upper surface filter portion 33 located corresponding to the upper surface suction port 13, and the lower half Constitutes the front opening portion 28 of the front panel main body 22 and the lower filter portion 34 located above the front opening portion 28.

When the air filter 21 is mounted on the filter mounting frame 20 of the front side frame 12, the filter frame portion 37 located at an intermediate portion of the lower filter portion 34 is located at the position of the upper gap 35 of the front suction port 29. It is configured to correspond. Further, when the air filter 21 is mounted on the filter mounting frame 20 of the front side frame 12, the side frame portions 38 located on both sides of the lower end portion of the lower filter portion 34 form the side gap 36 of the front suction port 29. It is configured to correspond to the position of.

The filter frame portion 37 and the side frame portion 38 of the air filter 21 have a predetermined design.
For example, the front panel main body 22 constituting the front panel 3
When the shielding panel 23 is made of an ivory or light color, the filter frame portion 37 and the side frame portion 38 are made of a dark blue or metallic color tone.
Further, the filter frame portion 37 and the side frame portion 38 may be configured to have the same color as the front panel main body 22 and the shielding panel 23, and may be configured so as to have an uneven design.

In such a configuration, the upper gap 35 generated when the front suction port 29 is formed in the front panel 3.
In addition, the net portion of the air filter 21 is not exposed from the side gap 36, so that a predetermined design surface can be formed and the appearance is not spoiled. Air filter 2
Since the design is constituted by using 1, the design can be formed easily and at low cost.

Although the case where the front panel main body 22 and the shielding panel 23 are integrally formed of synthetic resin is considered, the same configuration is applied when the shielding panel 23 is formed separately from the front panel main body 22. can do. In this case, the shielding panel 23 is designed to be smaller than the front opening 28 of the front panel main body 22 so that an upper gap 35 and a side gap 36 are generated.

[Front Panel Reinforcement Member] As shown in FIG. 3, a welding projection 41 is provided on the rear surface of the front panel main body 22 so as to be located near the upper edge of the front opening 28.
An engagement projection 42 is provided on the rear surface of the shielding panel 23 so as to be located near the upper end. As shown in FIG. 4, three sets of welding projections 41 are provided at two locations separated from each other in the length direction of the front panel main body 22. The engagement protrusion 42 is provided on the back surface of the shield panel 23 corresponding to the same longitudinal position as the position where the welding protrusion 41 is provided. A base 43 provided and a locking portion 4 bulging laterally from the tip of the base 43
4 are arranged opposite to each other. The base portions 43 of the two pins 45 are elastically deformable in directions in which the locking portions 44 at the distal ends approach each other.

A reinforcing member 51 as shown in FIG. 7 is attached using the welding projection 41 of the front panel main body 22 and the engagement projection 42 of the shielding panel 23. Reinforcement member 51
Constitutes a welded end 52 whose upper end is welded to the back surface of the front panel main body 22. The welding end 52 is shown in FIG.
As shown in FIG. 3A, an insertion hole 54 having a substantially triangular shape and into which the welding projection 41 of the front panel main body 22 can be inserted is provided. The lower end of the reinforcing member 51 forms an engagement end 53 that engages with the back surface of the shielding panel 23. As shown in FIG. 7A, the engagement end 53 is provided at the center of the shielding panel 2.
An engagement hole 55 for receiving the third engagement protrusion 42 is provided. A central portion connecting the welding end portion 52 and the engagement end portion 53 has a width smaller than both end portions when viewed from the front, and forms a curved intermediate coupling portion 56 as shown in FIG. 7B. ing.

The reinforcing member 51 as described above is attached to the back surface of the front panel 3, as shown in FIGS. The welding projection 41 of the front panel main body 22 is inserted into the insertion hole 54 of the reinforcing member 51 and the engagement projection 42
Is inserted into the engagement hole 55 of the reinforcing member 51. At this time,
By pressing the engaging end 53 of the reinforcing member 51 against the engaging projection 42, the inner peripheral surface of the engaging hole 55 is

5 is released from the inner peripheral surface, the base 43 of the pin 45 returns to the steady state, and the locking portion 44 engages with the edge of the engagement hole 55. In this state, the welding end 5 of the reinforcing member 51 is
2 is welded to the back surface of the front panel main body 22.

The front panel 3 is a long object. If the front panel 3 is formed by integral molding of a synthetic resin, the front panel 3 may be warped or distorted to impair the aesthetic appearance. In particular, the shielding panel 23 that is disposed apart from the front panel main body 22 to provide the front suction port 29 may be deformed because there is no support in the vicinity of the front suction port. When the front panel main body 22 and the shielding panel 23 are formed by integral molding of a synthetic resin, it is difficult to simultaneously configure the support members, and even if such a configuration is created, the configuration may be inconspicuous. Have difficulty.

In the present invention, the above-described reinforcing member 51 is attached to the back surface of the front panel 3 to prevent the shielding panel 23 from warping or deforming. Even when it is seen from the suction port 29, it can be made inconspicuous. In addition, the intermediate connecting portion 56 of the reinforcing member 51 can be configured with a different color tone or a different design from the front panel main body 22 and the shielding panel 23. As shown in FIG. 5, when a position corresponding to the upper gap 35 of the air filter 21 is configured by a filter frame portion 37 having a predetermined design, the intermediate connecting portion 56 of the reinforcing member 51 is connected to the filter frame portion 37. The same design can be obtained.

The load that pulls the shielding panel 23 forward can be prevented from being deformed by the support of the reinforcing member 51. If the force that pulls the shielding panel 23 forward becomes overloaded, the engaging projection The portion 42 is provided with the engagement hole 5 of the reinforcing member 51.
5 can be prevented and the entire front panel 3 can be prevented from being damaged. The end shape of the reinforcing member 51 is not limited to the illustrated one, and the numbers and shapes of the welding projections 41 and the engagement projections 42 are not limited to the illustrated ones. Further, as a method for welding the welding end portion 52 to the back surface of the front panel main body 22, spot welding or the like can be used.
Instead of welding, it is also possible to employ bonding with an adhesive, fastening with screws or the like.

[Other Embodiments of Reinforcing Member] (A) It is also possible to use a reinforcing member 61 as shown in FIG. Here, an engagement projection 71 is protruded from the rear surface of the front panel body 22 near the upper edge of the front opening 28. In addition, an engagement projection 72 is provided on the rear surface of the shielding panel 23 so as to be located near the upper end. Engaging projection 71,
Reference numeral 72 denotes a configuration similar to that of the engagement protrusion 42 described above, and a plurality of pins each having an elastically deformable base portion and a locking portion bulging laterally from the tip of the base portion are erected in opposition. Things.

The reinforcing member 61 has an upper engaging end 62 which engages with the engaging projection 71 of the front panel body 22 at the upper end, and engages with the engaging projection 72 of the shielding panel 23 at the lower end. The lower engaging end 63 is formed. Upper engagement end 62,
The lower engagement end 63 is provided with engagement holes 64 and 65 for receiving the engagement protrusions 71 and 72, respectively.
A central portion connecting the upper engagement end portion 62 and the lower engagement end portion 63 has a width smaller than both ends when viewed from the front, and forms a curved intermediate coupling portion 66.

The reinforcing member 61 as described above is provided with the engaging holes 6 formed in the upper engaging end 62 and the lower engaging end 63.
4 and 65 are attached to the front panel 3 by receiving the engagement projections 71 and 72, respectively. This reinforcing member 61 is used when a load is applied to the shielding panel 23.
It supports the shielding panel 23 to prevent deformation. When an overload is applied in a direction in which the shielding panel 23 is separated from the front panel main body 22, the engaging projection 72 provided on the back surface of the shielding panel 23 engages with the engaging hole 65 of the lower engaging end 63. And the front panel 3 can be prevented from being damaged. Further, when an overload is applied in a direction of pressing the shielding panel 23 toward the front panel 22, the engaging projection 71 provided on the back surface of the front panel main body 22 is moved to the upper engaging end 6.
The front panel 3 can be prevented from being damaged by detaching from the second engagement hole 64. (B) It is also possible to use a reinforcing member 81 as shown in FIG.

The lower end of the reinforcing member 81 has the shielding panel 23.
A middle end 83 which is curved and extends upward and rearward, and a contact upper end contacting the front end of the middle portion 83 with the back surface of the front panel body 22. 84. In this case, the attachment of the reinforcing member 81 is completed by welding the welded end 82 to the vicinity of the upper end of the back surface of the shielding panel 23. The contact upper end portion 84 of the reinforcing member 81 is in contact with the back surface of the front panel main body 22 in a steady state, or has a slight gap.

When the shielding panel 23 is pulled in a direction away from the front panel main body 22, the contact upper end portion 84 of the reinforcing member 81 contacts and supports the rear surface of the front panel main body 22, so that the shielding panel 23 is supported. Can be prevented from being deformed. When an overload is applied in the direction of pressing the shielding panel 23 against the front panel main body 22, the contact upper end portion 84 of the reinforcing member 81 separates from the rear surface of the front panel main body 22, and Damage can be prevented.

[Second Embodiment] The front panel 3 is shown in FIG.
A configuration as shown in FIG. 12 is also possible. Here, a front panel main body 22 having a front opening is integrally formed with a shielding panel 23 arranged at a predetermined distance in front of the front panel main body. The front panel main body 22 is located near the upper edge of the front opening 28.
A gap is provided between the upper suction port 9 and the shielding panel 23.
It is set to 1. Similarly, a lower suction port 92 is provided near the lower edge of the front opening 28 with a gap provided between the front panel main body 22 and the shielding panel 23. The room air sucked from the upper suction port 91 and the lower suction port 92 both passes through the front opening 28 provided in the front panel main body 22 and is introduced into the heat exchanger.

In this case, since the room air can be introduced into the heat exchanger through the upper suction port 91 and the lower suction port 92, the room air can be sufficiently suctioned from the front side. Further, as is apparent from FIG.
Since most of the front opening 28 is hidden by 3, the net portion and internal components of the air filter are not seen from the front, and the appearance is not spoiled. Further, since there are no movable parts in the shielding panel 23, there is no change in the design during operation and during stoppage, and the cost can be reduced by omitting an operation mechanism such as an actuator.

When the front panel main body 22 and the shielding panel 23 are formed by integral molding of a synthetic resin, a slight gap is formed in a front view due to the removal of the mold as in the above-described embodiment. For example, in FIG. 11, an upper gap 95 and a lower gap 96 are formed for the upper suction port 91 and the lower suction port 92, respectively. In this case, it is conceivable that a part of the air filter disposed in the front opening 28 of the front panel main body 22 is visible through the upper gap 95 and the lower gap 96. In this case, as in the case of the above-described air filter, the upper gap 95 and the lower gap 96 are formed.
By designating the position corresponding to a filter frame portion having a predetermined design, the design property is not impaired.

Further, it is conceivable that the same reinforcing member as described above is disposed near the upper suction port 91 and the lower suction port 92. In this case, by providing the reinforcing member at both the upper suction port 91 and the lower suction port 92, the strength of the shielding panel 23 can be increased and deformation can be prevented. Of course, a reinforcing member may be provided near one of the upper suction port 91 and the lower suction port 92.

[Other Embodiments] A gap can be provided between the front panel body 22 and the shielding panel 23 only near the lower edge of the front opening 28 of the front panel 22 to provide a front suction port. is there. Also in this case, a predetermined design can be applied to a portion that can be seen through the gap of the air filter, and the reinforcing member can be provided near the front suction port.

[0043]

In the air conditioner according to the present invention, since the front opening is invisible from the front due to the shielding panel, excellent design can be maintained, and the front panel body and the shielding panel can be maintained. Through the gap provided between the heat exchanger and the front side, and sufficient air can be introduced to the heat exchanger side.
