Description

Air Conditioner {AIR CONDITIONER}

The present invention relates to an air conditioner in which a filter is detachably disposed on an inner surface side of a cabinet suction port.

Conventionally, in the structure of the indoor unit of a general air conditioner, an inlet for sucking air from the upper part of the front surface of the cabinet to the ceiling surface is formed, a spout is formed in the lower part of the front surface of the cabinet, and an air passage from the inlet to the spout is provided. It is known that filters, heat exchangers and fans are arranged in this order. In the suction port, a lattice suction grille is formed mainly for aesthetic reasons. Since the suction grille is formed in the shape of a lattice, the larger the size, the more expensive the mold production and the like, which has become one factor of the cost increase.

On the other hand, as disclosed in Patent Literature 1, recently, an air conditioner having a simple and refreshing appearance has appeared on the front face of the cabinet without providing an intake port. In this case, when the intake port is formed only on the cabinet ceiling surface, the air conditioner is generally installed near the ceiling of the room, and thus, from the user's eyes, it is not normally seen until the rear side of the ceiling surface of the cabinet. Then, in the air conditioner of the structure which forms a suction port only in the ceiling surface of a cabinet, it can also be considered to remain as an opening, without forming a suction grille.

Japanese Patent Application Publication No. 2009-63257

However, in the air conditioner of the said structure, when it tries to remain as an opening without providing a suction grill in a suction port, there existed the following problems.

That is, in the air conditioner of the said structure, the movement path which moves a filter so that insertion and removal is possible is formed, and a filter moves a movement path, and is interposed between the inlet port and a heat exchanger. Since a minimum space can be secured between the ceiling surface of the cabinet in which the suction port is formed and the heat exchanger due to design constraints, the movement path is set along the inner surface of the cabinet suction port. That is, a movement path is formed adjacent to the suction port.

By the way, a filter is comprised from the filter net and filter frame which were integrally shape | molded normally. Since the filter requires flexibility, the larger the size of the filter, the more likely the twist and wave of the entire filter are caused by the residual stress after molding.

Therefore, if the filter in which the twist or the wave is generated is moved in the movement path, when the suction grille is not formed in the suction port, a part of the filter tip, which is deformed by a mountain curve, protrudes from the suction port. Then, the filter portion protruding from the suction port is caught by the rear edge of the suction port, and there is a problem that the filter cannot be set at a predetermined position.

This is because in the conventional air conditioner, since the suction grill plays a part of the moving path, even if the filter has distortion such as torsion or undulation, the filter can smoothly move the moving path by suppressing the deformation. This was a problem newly generated by removing the suction grille.

Therefore, in view of the above, the present invention does not provide a suction grill that covers the suction port as a whole, thereby reducing costs and without impairing aesthetics, and the filter smoothly reaches a predetermined position without being caught by the end edge of the suction hole in the course of the movement. It is an object of the present invention to provide a mobile air conditioner.

In order to achieve the above object, the air conditioner according to the present invention includes a suction port formed on the ceiling surface of the cabinet, a filter disposed on the inner surface side of the cabinet suction port, and a movement path for inserting and detaching the filter. And the suction grille is not formed in the suction port as a whole, and an induction part is provided to guide the insertion tip of the filter so as not to be caught by the end edge of the suction port when the filter is inserted into the movement path.

According to the above configuration, by providing an induction part without forming a suction grill covering the suction port as a whole, even when deformation is generated in the filter, the filter is smoothly guided in the movement path by guiding the deformed portion of the filter to the movement path. It is possible to move from.

 In addition, forming a suction grill on a part of the suction port is not a problem. For example, since the front side of the suction port can be recognized by the user, only the front side of the suction port can form the suction grille. That is, in this invention, it aims at suppressing the cost increase by forming the large suction grill which covers the suction port as a whole, and it does not matter whether a suction grill is formed auxiliary part of the suction port.

Specifically, the induction part includes the following. When the moving path is formed in the cabinet front and rear directions, when the filter is inserted into the moving path from the front of the cabinet and moved to the rear of the cabinet, a problem arises that the insertion end of the filter is caught by the rear end edge of the suction port. In this case, the rear end edge of the suction port can be inclined with respect to the cabinet left and right directions, and the rear end edge of the inclined suction port can be used as the guide portion.

In the above configuration, one side of the left and right corner portions of the rear end edge of the suction port is arranged to be polarized on the cabinet front face than the other side. Therefore, when the filter is inserted into the movement path and moved toward the rear of the cabinet, the insertion end of the filter is first of the corners of the left and right corners of the rear end edge of the inlet port, which are closer to the cabinet front face (hereinafter, the front corner part). The point of intersection with the movement of the filter moves to the other side.

Therefore, when a part of the filter insertion part has a mountain-shaped curved part, only one point is in contact with the rear end edge of the suction port in order from one end of the filter deformed part to the other end. In this way, since the insertion end of the filter and the rear end edge of the inlet are not in contact with two or more points at the same time, the filter portion which is in point contact with the rear end edge of the inlet is pressed against the rear end of the inlet smoothly. It is directed to the path of travel.

 Moreover, in the said structure, a movement path consists of a pair of left and right holding rails which hold the left and right both sides of a filter, and each holding rail is an outer rail located in the filter surface side, and the inside located in the filter back surface side. On the outer rail of the holding rail which has a rail and is located in the corner part side of the side near the cabinet front surface among the left and right corner parts of the rear end edge of a suction port, the protrusion part which protrudes toward the inner rail from the front position of the said corner part may be formed. It may be. In this case, the protruding portion is added to the rear edge of the suction port to become the induction portion.

In the above configuration, the left and right both sides of the filter move inside the holding rail while being held by the holding rail. The tip of the filter side portion (hereinafter referred to as the filter side portion on the protrusion side) that moves the holding rail on the side where the protrusion is formed can be pushed down by contacting the protrusion, and passes through the front side corner in a state spaced apart from the outer rail. As a result, the filter passes through the front corner without interlocking with the front corner and intersects with the trailing edge of the suction port. Then, as described above, the filter is smoothly guided to the movement path by the rear edge of the suction port.

That is, since the left and right corner portions of the rear end edge of the inlet are at the inflection point at which the rear end edge of the inlet and the left and right side end edges intersect, when the deformation portion of the curve of the mountain shape is present at the insertion end of the filter, The direction from the left and right corners is more easily caught than the portion. Therefore, by forming the projection part in the induction part, the filter side part of the projection part side is pushed down for every mountain-shaped curved deformation | transformation part, and it passes through the lower surface of a front side corner part, and passes. The filter at the front corner can be avoided.

As described above, by inclining the rear edge of the inlet at the inlet and forming a projection, it is possible to smoothly guide the filter to a predetermined position while ensuring that the filter is not caught by the rear edge of the inlet. do.

In addition, it is also possible to employ | adopt only a protrusion part in an induction part. In this case, the rear end edge of the suction port is formed along the cabinet left and right directions as before. And a movement path consists of a pair of left and right holding rails which hold | maintain both left and right both sides of the said filter so that the cabinet can move to the front-back direction, and each holding rail is an outer rail located in the said filter surface side, and a filter back side The inner rail which is located in the at least one of the said pair of holding rails, the protrusion which protrudes toward the inner rail in the front position of the rear edge of the said inlet port is formed, The protrusion part is comprised You can do

In the above configuration, the projection is formed while the rear end edge of the suction port is formed parallel to the cabinet left and right, so that the entire insertion end of the filter passes through the rear end edge of the suction port at the same time. The protrusions may be formed on both outer rails of the left and right holding rails or may be formed on one side.

As described above, according to the present invention, since the suction port is not provided with the suction grill which covers the suction port as a whole, when the filter is inserted into the movement path, an induction part is provided which guides the insertion tip of the filter so as not to be caught by the end edge of the suction port. In addition, it is possible to obtain an air conditioner which is capable of smoothly moving to a predetermined position without reducing the cost, without damaging the aesthetics, and without the filter being caught in the moving path.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described based on drawing. 1 is an external perspective view of the indoor unit of the air conditioner viewed from below, FIG. 2 is an external perspective view of the indoor unit of FIG. 1 viewed from above, and FIG. 3 is a cross-sectional view of the indoor unit of FIG. 2, respectively. .

As shown in FIGS. 1-3, the indoor unit is equipped with the heat exchanger 1 and the fan 2, and these are integrated in the cabinet 3. As shown in FIG. The suction port 4 is formed in the ceiling surface of the cabinet 3, and the jet port 5 is formed in the lower part of the front surface of the cabinet 3. In the cabinet 3, an air passage 6 from the intake port 4 to the blowout port 5 is formed, and the heat exchanger 1 and the fan 2 are disposed in the air passage 6.

A filter 7 is disposed between the intake port 4 and the heat exchanger 1 to remove dust from the indoor air sucked in the intake port 4. The horizontal louver 8 is rotatably provided in the front surface of the jet port 5, and the direction of the wind which blows off from the jet port 5 can be changed to an up-down direction. The vertical louver 15 is provided upstream of the horizontal louver 8. The vertical louver 15 rotates in the left and right directions. The vertical louver 15 changes the wind direction in the left and right directions.

In the air conditioner, an outdoor unit not shown for the indoor unit is installed outdoors. The outdoor unit includes a compressor, a heat exchanger, a four-way valve, an outdoor fan, and the like, and a refrigeration cycle is formed by these and the heat exchanger 1 on the indoor side. And the control apparatus which controls a refrigerating cycle is installed in an indoor unit. The control device comprising a microcomputer controls the refrigeration cycle and performs cooling and heating operation based on a user's instruction and detection signals of various sensors such as a temperature sensor that detects outdoor or external temperatures. At this time, the control device controls the driving of the fan motor and the opening / closing of the horizontal louver 8 in accordance with the cooling and heating operation.

4 is an exploded perspective view of the indoor unit. As shown. The cabinet 3 can be disassembled into a back plate 9, a right cover 10, a left cover 11 and a front panel 12 serving as a base, and the ceiling surface of the cabinet 3 includes these members. An enclosed, long opening in the left and right directions is formed. The filter guide member 13 is provided in the left-right direction center of this opening.

Thereby, the opening is divided into two at the left and right, and the suction ports 4 and 4 are formed at the left and right pairs. Filters 7 and 7 are arranged for each of the inlets 4 and 4. In addition, one inlet can be covered with one filter without using the filter guide member 13, and it can also divide into three or more inlet using the some filter guide member 13. As shown in FIG.

The front panel 12 is installed to open and close about a rotating shaft (not shown) formed thereon. The suction grille 4 which covers the whole suction port 4 is not formed in the suction port 4, and the suction port 4 remains an opening. In addition, the front grille 14 is detachably installed in the front side portion of the suction port 4 so as to make the suction port 4 invisible. As a result, the opening of the suction port 4 is blocked by the front grille 14 from the user and is not visible and does not damage the aesthetics.

The filter 7 makes the movement path 19 movable. The movement path 19 is formed in the front-rear direction of the cabinet 3, the front end of the movement path 19 is formed with the entrance and exit 20 through which the filter 7 enters, and the rear end of the rear plate 9 It is formed to face the top. The doorway 20 is formed in the front upper part of the indoor unit which opened the front panel 12. FIG. The movement path 19 is formed to be inclined toward the inlet port 4 along the heat exchanger 1 formed in the inverted V shape at the doorway 20, and after reaching the inlet port 4, the rear plate 9 is provided. It is formed along the inner surface of the ceiling surface of the cabinet (3).

The movement path 19 is comprised by the left and right pair of holding rails 21 and 22 which hold | maintain both the left and right sides of the filter 7. The holding rails 21 are formed at both side portions of the filter guide member 13, and the holding rails 22 are along the edges of the right cover 10 and the left cover 11 facing the inlet 4. Formed. Therefore, in the left and right suction ports 4 and 4, the positions of the holding rails 21 and 22 are reversed left and right. The holding rails 21 and 22 are provided with the outer rail 23 and the inner rail 24, respectively, and the side part of the filter 7 is hold | maintained between the outer rail 23 and the inner rail 24. As shown in FIG. In addition, the surface of the filter guide member 13, ie, the surface of the outer rail 23, constitutes a part of the ceiling surface of the cabinet 3.

The outer rail 23 of the holding rails 21 and 22 has a structure divided back and forth, the front side of the outer rail 23 is composed of the lower surface portion of the front grill 13, and the rear side of the cabinet 3 It is constructed by the ceiling surface. In this way, the movement path 19 is formed in contact with the suction port 4 at the rear side of the suction port 4. Therefore, as shown in FIG. 8, when the mountain-shaped bend deformation parts X1, X2, etc. exist at the insertion tip of the filter 7, these deformation parts X1, X2 are the rear end edge 25 of the suction port. ).

Therefore, in this embodiment, even if the deformation | transformation part X1, X2 etc. exist in the insertion tip of the filter 7, for example, the insertion tip of the filter 7 is caught by the inlet 4, and movement of the filter 7 is not inhibited. In order to guide the moving path 19 is installed. Specifically, the guide portion includes a rear end edge 25 of the suction port inclined with respect to the left and right direction of the cabinet 3 and a protrusion 26 formed on the outer rail 23. Hereinafter, the trailing edge 25 and the projection 26 of the suction port will be described in detail.

As shown in FIGS. 5 and 6, the rear end edge 25 of the suction port is inclined with respect to the left and right directions of the cabinet 3. That is, one side of the left and right corners of the rear end edge 25 of the inlet port is polarized on the cabinet front side than the other side. In addition, in this embodiment, the direction of the inclination of the rear end edge 25 of the suction inlet formed in the left and right suction ports 4 and 4 is formed symmetrically from a viewpoint of an external appearance.

Specifically, in the inlet 4 on the left side, the left corner of the rear end rim 25 of the inlet is the front corner 25a (the corner near the front side of the cabinet among the left and right corners of the rear end of the inlet). In the inlet 4 on the right side, the right corner of the rear edge 25 of the inlet becomes the front corner 25a. The shape of the rear end edge 25 of the intake port may be formed to be inclined in either of the left and right directions, and can be made into a smooth curved shape as in the present embodiment, and is shown as another form, for example, in FIG. 7. As mentioned above, it is also possible to make it linear.

If the rear end edge 25 is formed to be inclined with respect to the suction port 4, the opening area becomes small by that amount. Therefore, in this embodiment, the auxiliary grille 16 is formed between the shape of the intake port 4 which is originally rectangular shape, and the trailing edge 25 of the inclined intake port, and secures the opening area of the intake port 4; I'm trying to. In addition, although the auxiliary grille 16 and the rear end edge 25 of the suction port are integrally formed in the back plate 9, it is also possible to form it separately from the back plate 9.

As shown in FIGS. 9-11 and 3, the projection part 26 is a front side corner part 25a in the outer rail 23 of the holding rail located in the side of the front side corner part 25a. Is formed in the front position of the. In this embodiment, the projection part 26 is formed in the holding | maintenance rails 22 and 22 for both the suction ports 4 and 4 of right and left. In addition, the projection part 26 pushes down the side part of the filter 7, and passes the front corner part 25a in the state separated from the outer rail 23, and the filter 7 smoothly hits the projection part 26. It is desirable to form slopes in the projections so that they can pass. The holding rails 22 and 22 formed in the left and right suction ports 4 and 4 are symmetrical in shape.

In addition, the slope portion 27 is preferably formed at the tip of the side of the filter 7 so that the filter 7 can smoothly pass over the protrusion 26. In the present embodiment, slopes are formed on both side ends of the filter 7 and the projections 26 (see FIG. 8).

In addition, the protrusion part 26 may form one of predetermined heights, and may form the plurality of protrusion parts 26, and may raise it to predetermined height step by step. In this embodiment, the three protrusion parts 26a. 26b and 26c which made height high step by step are formed. As described above, when a plurality of the protrusions 26 are formed, vibration occurs whenever the filter 7 contacts each of the protrusions 26.

Thereby, as shown in FIG. 8, when the deformation | transformation part X2 generate | occur | produces near the filter side part, the deformation | transformation part X2 is moved as much as possible to the center of the filter 7 (deformation part X1) by vibration. Position). As a result, after reducing the risk of catching the deformation | transformation part X2 in the front side corner part 25a as much as possible, the side part of the filter 7 can be pushed down and it can pass through the front side corner part 25a.

Moreover, it is preferable to form the projection part 26 in front of the joining surface which the back plate 9 and the left and right cover join. That is, the joining surface of the back plate 9 and the left and right covers becomes a joint of the holding rail 22. In this part, a gap and a step are likely to occur, so there is a danger of catching the insertion tip 30 of the filter 7. Therefore, by arranging the projections 26 at the front position of the joining surface, the filter 7 can avoid contact with not only the front corner 25a but also the joining surface, and prevent the latching in advance. Can be.

9-11 and 3 show the joint surface 17 of the back plate 9 and the left cover 11 in the suction port 4 on the left side. In this embodiment, the protrusion part 26c located in the back of three protrusion parts is formed so that the bonding surface 17 may be exceeded. Moreover, the joining surface 18 of the back plate 9 and the right cover 10 in the right suction port 4 is formed in the position immediately before the front side corner part 25a (refer FIG. 6). Therefore, since the projection part 26 is formed in the front position rather than the joining surface 18, the engagement of the filter 7 in this joining surface 18 can also be avoided.

As shown in Fig. 8, the filter 7 is a filter made of a resin in which the filter net 28 and the filter frame 29 are integrally molded. The larger the size, the larger the insertion tip of the filter due to residual stress ( It is easy to generate | occur | produce mountain-shaped bending deformation | transformation part X1 and mountain-shaped bending X2 in 30).

The air conditioner of the said structure WHEREIN: The filter 7 is demonstrated until it inserts in the entrance 20 of the movement path 19, and sets it to a predetermined position. 9-11 is A-A sectional drawing of the indoor unit in FIG.

First, as shown in FIG. 9, the front panel 12 is opened and the filter 7 is inserted in the movement path 19 in the entrance 20 shown in the upper part of the indoor unit. The filter 7 moves inside the movement path 19 along the heat exchanger 1 toward the inlet 4.

After the insertion tip 30 of the filter 7 reaches the inner surface of the inlet 4, ie after reaching the outer rail 23, it contacts the outer rail 23, along the cabinet along the inlet 4. It moves to the rear of (3), and contacts the protrusion part 26 formed in front of the front side corner part 25a.

The protrusions 26a, 26b and 26c are formed so that the height thereof is increased step by step, and a slope is formed on the contact surface with the filter 7 of each of the protrusions 26a, 26b and 26c. Moreover, the slope part 27 is formed in the front-end | tip of the side part of the filter 7. For this reason, the side part of the filter 7 can pass smoothly over each projection part 26a, 26b, and 26c, and generate | occur | produces a vibration when passing over each projection part 26a, 26b, and 26c.

As shown in FIG. 10, the filter 7 which has crossed the protrusion part 26 can be pushed down by the protrusion part 26, and is separated from the outer rail 23 of the front corner part 25a. Pass down. In addition, although the protrusion part 26 is formed only in the holding rail 22 as mentioned above, you may form in the holding rail 21. As shown in FIG.

In the inner rail 24, the inclination part 31 is formed in the position back of the front corner part 25a so that the distance with the outer rail 23 may become narrow gradually. Moreover, the groove part 32 which can fit the insertion tip 30 of the filter 7 continuously in the inclined part 31 is formed in the rear end part of the movement path 19. As shown in FIG.

Therefore, the filter 7 which passed the front side corner part 25a is led to the groove part 32 by contacting the inclination part 31, as shown in FIG. And finally, as shown in FIG. 3, the insertion tip 30 of the filter 7 is fitted to the groove part 32, and is fixed.

The movement path 19 is terminated at the front door at the doorway 20, but the inner rail 24 of the retaining rails 21 and 22 extends to the front end portion 1a of the heat exchanger 1 as it is and smoothly. It is formed to draw an arc. And the back side of the filter 7 which was not introduce | transduced into the movement path 19 is hold | maintained by the inner rail 24. As shown in FIG. The rear end of the filter 7 is fixed by being inserted into the drain pan 33 located at the front end of the heat exchanger 1 while being curved by elastic deformation. By the above operation, the filter 7 is interposed between the intake port 4 and the heat exchanger 1 in the air passage 6.

As mentioned above, the cabinet 3 is a prefabricated structure composed of a plurality of members without using a large-size molded body. Thereby, productivity can be kept favorable, without requiring a large metal mold | die.

In this embodiment, since the cabinet 3 is a prefabricated type, the heat exchanger 1 and the fan 2 accommodated in the cabinet 3 are the support parts formed in the left and right inner surface of the back plate 9 as shown in FIG. It is attached to the back plate 9 via 40 and 41. Therefore, a large load is applied to the support parts 40 and 41 of the back plate 9. In this way, when a large load is applied to the left and right sides of the back plate 9, when the rigidity of the back plate 9 is weak, torsion occurs from the left and right sides.

Therefore, in this embodiment, as shown in FIG. 5, FIG. 13, and FIG. 14, the uneven | corrugated part 42 which has an uneven shape continuous in the left-right direction of the cabinet 3 is provided in the upper part of the back plate 9 It forms so that the rigidity of the whole back plate 9 may be improved. In addition, it is preferable to form a rib in each of the recesses 43 constituting the uneven portion 42 in that the rigidity can be further increased. The uneven portion 42 is formed by alternately repeating the concave portion 43a formed on the inner surface side of the back plate 9 and the concave portion 43b formed on the outer surface side of the back plate 9. That is, when the back plate 9 is viewed from the inner surface side, the convex portion adjacent to the concave portion 43a becomes the concave portion 43b formed on the outer surface side of the back plate 9. Moreover, when the back plate 9 is seen from the outer surface side, the convex part adjacent to the recessed part 43b becomes the recessed part 43a formed in the inner surface side of the back plate 9.

As for the shape of the ribs, the longitudinal ribs 44 extending in the longitudinal direction, the horizontal ribs 45 extending in the horizontal direction, or the grid-shaped ribs 46 can be appropriately formed. With respect to the lattice ribs 46, the ribs are formed in the longitudinal and horizontal directions, whereby the longitudinal and stiffness of the back plate can be improved. When the ribs are formed to be inclined at an angle, the torsion of the left and right sides of the back plate can be effectively prevented. .

Although there is no restriction | limiting in particular about the kind of rib formed in each recessed part 43, It is preferable to form the longitudinal rib 44, the horizontal rib 45, and the lattice rib 46 in a balanced manner. In this embodiment, as shown in FIG. 5 and FIG. 13, the lattice ribs 46 are all formed in the recess 43a formed on the inner surface side of the back plate 9. Further, among the lattice ribs 46, ribs are formed in the central concave portion 43a where the filter guide member 13 is provided in the longitudinal and horizontal directions, and all the other concave portions 43a are inclined at an angle to the rib. Forming.

13 and 14, the vertical ribs 44 and the horizontal ribs 45 are orthogonal to the recess 43b formed on the outer surface side of the back plate 9. By forming these ribs in a balanced manner, the rigidity of the entire back plate can be improved.
