Air conditioner

Technical field

The present invention relates to the indoor unit of air conditioner, particularly be installed in the unlimited mechanism of front panel of the indoor unit of indoor eminence.

Background technology

The indoor unit of air conditioner is made up of the casing main body with resin forming that constitutes this indoor unit rear portion, the unit that blows out that constitutes the trim main body of this indoor unit front face and constitute this indoor unit lower face.In this casing main body, be assembled with heat exchanger and pressure fan and other machines as the functional part of air conditioner, on the trim main body, be provided with from the face side of indoor unit suck the anterior grid of room air and from the indoor unit the top air intake grill of air in the facial suction chamber, air cleaner and these grids relatively are accommodated in inside.In addition, in blowing out the unit, be formed with heat exchanger and regulate the wind path that blows out that the air of temperature and humidity flows, near this blows out the air blow-off outlet of wind path terminal, be provided with the wind deflecting plate that makes the air-flow deflection that blows out from inflatable mouth.In addition, be inhaled into the room air of indoor unit from the top air intake grill of the anterior grid of indoor unit face portion and last face, remove dust by air cleaner, regulate temperature and humidity through heat exchanger, deliver to by pressure fan and to blow out in the wind path, be sent to indoor once more from the air blow-off outlet after making the air-flow deflection by deflecting plate again.

Usually; the indoor unit of air conditioner all is arranged on the eminence of wall near ceiling; the air that the temperature and humidity that blows out from eminence all regulates; the interior space that the people lived is adjusted to comfortable living environment; but because the on-stream dust of removing from room air can be deposited on the air cleaner, this just needs regular cleaning air filter.In addition, air conditioner owing to also can adhere to dust on heat exchanger and the pressure fan, so also equally with air cleaner needs to clean every now and then after long-time the use.But, the indoor unit of air conditioner is as foregoing, owing to be located at the eminence of the close ceiling of wall, therefore when cleaning air filter, heat exchanger and pressure fan etc., just have to climb on pedal and the two-sided ladder, thereby have to cleaning under the unsure state very much.

Improve the convenience of cleaning in order to remove this problem, proposed all technical schemes in the past.For example, open in the 2001-182957 communique (hereinafter referred to as prior art 1) the spy and to disclose following technology, as shown in Figure 14, adopted the structure that front panel 51 can be moved by bindiny mechanism 52 in the indoor unit front face side downwards, can and close the inside of indoor unit from open-front, can take out cleaning to built-in air cleaner 50 by opening front panel 51, like this, just can realize improving the convenience of cleaning air filter.

Also have, disclose following indoor unit for air conditioner in special permission No. 3254104 (hereinafter referred to as prior art 2), as shown in Figure 15, its structure is that air cleaner 60 and front panel 61 can be opened wide in the front lower of indoor unit simultaneously.That is, can be that rotate at the center with its underpart owing to the front panel 61 of being located at the indoor unit front face side is mounted to, front panel 61 is to rotate under the state that air cleaner 60 has been installed in its rear side.Under the situation of having carried out this rotation, as shown in the figure, front panel 61 hangs down with the state of surface and back side counter-rotating below the front side of indoor unit, and the air cleaner 60 that is installed in these front panel 61 back sides is exposed to nearby.Therefore, unload air cleaner 60 easily, also just can clean easily.Front panel also can unload from indoor unit under such state that hangs down, and also just can take off and clean.

Have again, open in the flat 11-23000 communique (prior art 3), announced the indoor unit of the air conditioner of the cleaning of carrying out air cleaner easily the spy.The front face that air cleaner is divided into the front panel rear side that is installed in indoor unit, with upward facial two parts that are installed in upper air intake panel inboard facial on the indoor unit, the air cleaner of front face can be pulled out from the space of front panel bottom, as shown in figure 16, last facial air cleaner 70 constitutes and can pull out with the upper air intake panel, like this, just can cleaning air filter 70 and upper air intake panel 71.In addition, when these air cleaners 70 and upper air intake panel 71 are taken out, just opened wide, thereby can be cleaned heat exchanger in this space etc. in the inner space on indoor unit top.

But, the indoor unit of air conditioner all is installed in the eminence of wall near ceiling usually, therefore, during each machine in scavenging air filter and indoor unit, the operator of this cleaning need climb up pedal and two-sided ladder, under unsure state, clean, have under this unsure state air cleaner etc. unloaded down and clean.

For example, in above-mentioned prior art 1, in Figure 14, in order to make air cleaner 50 can be removed, and adopted front panel 51 is installed to structure on the indoor unit by bindiny mechanism 52, front panel 51 is moved to the front lower of indoor unit, make air cleaner 50 be removed easily.The mobile of such front panel 51 carries out from body weight by it, at first, when this front panel 51 is removed with the locking of indoor unit, though the operator is supporting this front panel 51, but by bindiny mechanism 52, front panel 51 is at first shifted to the operator nearby, promptly moves to the side-prominent direction of operator, afterwards, move and stop to the front face parallel beneath of indoor unit.Therebetween, the operator stands on pedal or the two-sided ladder and is in an unsure state, front panel 51 is outstanding towards the operator who is in described labile state, in addition, as the operator, sometimes do not recognize that front panel 51 is outstanding like this yet, and do not know what degree front panel can be projected on earth more the time.Therefore, just be not easy to avoid outstanding like this front panel 51, and, just have under this unsure state, adopt reluctantly inappropriate posture sometimes in order to avoid front panel.

In addition, in the prior art 1, adopted bindiny mechanism 52, the therefore textural complexity that becomes, the number of parts also increases, and assembling operation also needs the long period, and needs to promote the price of air conditioner.

Also have, in above-mentioned prior art 2, in order to make air cleaner 60 can be removed, as shown in Figure 15, being installed at air cleaner 60 under the state at back of front panel 61 this front panel 61 is that middle imago counter-rotating is rotated like that with this bottom, make air cleaner 60 be in nearside (that is, operator's side) in the front lower of indoor unit front panel 61 is hung down, under this state, can take off the air cleaner 60 in front of being in easily.But, in order to take out air cleaner 60,, just need as above-mentioned in order to open wide front panel, front panel is rotated, and this rotation is carrying out from body weight by front panel.For this reason, in a single day indoor unit removes the locking on the top of front panel 61, then since its from body weight, front panel 61 rotates rapidly with its inertia force, near the head and the face that stand in the operator on pedal and the two-sided ladder etc. astatically.This occasion is also the same with above-mentioned prior art, as the operator, does not recognize also that sometimes front panel 51 is outstanding to the front like this, does not know also in the time of most that front panel on earth can be how much outstanding to the front, thereby can not separate the uneasiness sense that disappears when opening wide front panel.

Have again, in the above-mentioned prior art 3, air cleaner is divided into front face to be used and rear face two parts, as shown in figure 16, going up facial air cleaner 70 can together be drawn out with upper air intake panel 71, but the top that so last facial air cleaner 70 and upper air intake panel 71 are mounted pinnacled indoor unit, therefore, even a lot of occasion operators stand on pedal and the two-sided ladder and can not directly see, need will go up facial air cleaner 70 with hand under the situation of manual work and upper air intake panel 71 takes out from indoor unit cannot see, or be installed in indoor unit, even this operation only need make them slide, needing to require efforts, is not the operation of carrying out easily yet.

In addition, in the above-mentioned prior art 3, as mentioned above, air cleaner is divided into two parts, therefore, the parts number of components increases thereby form separately, in addition, just can not use the existing mold that is used to make single air cleaner from the front face of indoor unit to last face, other mould that feasible needs are different therewith and cause product price to rise, in addition, need clean this two air cleaners respectively, thereby cause the reduction of cleaning work efficient.

Having, is not only air cleaner again, also needs to make the machine such as pressure fan of indoor unit inside and blow out unit etc. also can clean easily.

The specific embodiment

Below, with reference to accompanying drawing embodiments of the invention are described.

Fig. 1 is the sectional view of indoor unit part of an embodiment of signal air conditioner of the present invention, the 1st, and casing main body, the 2nd, trim main body, the 3rd blows out unit, the 4th, front panel, the 5th, upper air intake panel, the 6th, air cleaner, 7a～7c are heat exchangers, the 8th, pressure fan, the 9th, the dish, the 10th that uncovers blows out wind path, the 11st, left and right sides wind deflecting plate, the 12nd, wind deflecting plate, the 13rd up and down, hinge, the 14th, diaxon connection hinge.

In with figure, the casing of indoor unit by casing main body 1 with trim main body 2 and blow out unit 3 and constituted.

Be assembled with (not shown) and pressure fans 8 such as being divided into a plurality of heat exchanger 7a～7c, other kind of refrigeration cycle parts and electronic unit in the casing main body 1.

Also have, trim main body 2 is installed in from the upper part of casing main body 1 until front portion (accompanying drawing upper left side), and its upper part and front portion are the frame shape basically as peristome.Also have,,,, the front panel 4 that rotary surface does not have concavo-convex planar structure has been installed by being arranged on the diaxon connection hinge 14 of its underpart as rotating mechanism in the front portion of trim main body 2 in order to improve the appearance design aesthetic feeling of indoor unit.And, the upper air intake panel that sucks room air is assembled on the trim main body 2, make its peristome of facing trim main body 2 upper parts, by making its slip, can take off from trim main body 2.Also have, air cleaner 6 is can be loaded on from the state group that trim main body 2 is taken on the trim main body 2, and the inboard of front panel 4 and upper air intake panel 5 is covered by heat exchanger 7.

Do not turn round when being in halted state at air conditioner, front panel 4 is in closed condition at illustrated position a usually.If furthered and remove the locking of casing to front panel 4 towards nearside (accompanying drawing upper left side) in the upper end of front panel 4, then a turning cylinder with diaxon connection hinge 14 is the center, front panel 4 is according to can be by counterclockwise turning to illustrated position b (below be referred to as first rotate) from body weight, like this, the part of the upper side of front panel 4 is opened and is formed an air suction inlet.Under the state that this position b opens, connect 14 pairs of front panels 4 of hinge by diaxon and apply a brake force, with suppress front panel 4 because of produce from body weight to anticlockwise rotatory force, front panel 4 just can be in position b maintenance stable status.Have again, left behind in the upper end of front panel 4, front panel 4 is turned to respect to position a rotated nearly 180 ° illustrated position c (below be referred to as second rotate) by resisting this brake force.The center of rotation of this moment is another root turning cylinder that diaxon connects hinge 14.At this position c, when being in position a, the surface and the back side of front panel 4 are inverted, and its back side becomes indoor living space one side (accompanying drawing upper left side).The state that front panel 4 is in this position c is referred to as front panel 4 and opens wide, like this, under the state that front panel 4 is opened wide,, can take off air cleaner 6 from trim main body 2 at an easy rate by catching the bottom of air cleaner 6 to leave behind with finger.

Also have, at the lower face of indoor unit, have packed into left and right sides wind deflecting plate 11 and up and down wind deflecting plate 12 blow out wind path 10 blow out unit 3, be installed in rotation on the casing main body 1 by hinge 13.Wind deflecting plate 12 when air conditioner shuts down, is in the state that position d blocks the inflatable mouth of the end that blows out wind path 10 up and down; When air conditioner shuts down, be in position e and rotate the state that opens wide this inflatable mouth.Also have, this blows out unit 3, by will with the latch-release of indoor unit casing, can counterclockwise rotate for middle mind-set with hinge 13, like this, become the state that hangs down from casing by hinge 13.Thus, can clean the each several part that blows out unit 3.

Here, in the casing of indoor unit, around pressure fan 8, disposed the heat exchanger 7a～7c that is divided into 3 sections.Be configured between the peristome of pressure fan 8 and trim main body 2 upper parts, a remaining heat exchanger 7c generally perpendicularly is configured between the peristome of pressure fan 8 and trim main body 2 face portion two heat exchanger 7a wherein and the 7b picture word of falling V shape.Then, disposing the air cleaner 6 that is installed on this trim main body 2 between these heat exchangers 7a～7c and the trim main body 2.This air cleaner 6 is the one that connect from the upper part of trim main body 2 to face portion, and it covers the peristome of upper part of trim main body 2 and the peristome of face portion.

Figure 2 shows that the outside drawing of the indoor unit of air conditioner when turning round and shutting down.3a is that fixing button, 15 is air suction inlet, has marked prosign with the corresponding part of Fig. 1.

Fig. 2 (a) is depicted as shut down indoor unit under the state of air conditioner, when air conditioner shuts down, the indoor unit that is arranged on indoor wall top is when the daily life place looks up, and the face portion that can see indoor unit is covered by the front panel 4 that the surface does not have concavo-convex flat surfaces to constitute; The lower face crested that can see indoor unit blows out the same of wind path 10 and is covered by the wind deflecting plate up and down 12 that does not have concavo-convex flat surfaces to constitute.Therefore, the indoor unit when shutting down, becoming in outward appearance does not have concavo-convex planar design on the whole, thereby can improve its aesthetic appearance, can coordinate with indoor other furniture and commodity simultaneously yet and can not produce the difference sense.

In addition, move along the direction shown in the arrow, then blow out unit 3 and on casing, fixedly be disengaged if will be arranged on the fixing button 3a of the side of indoor unit.Therefore, as illustrated in fig. 1, can be that rotate downwards from casing at the center with hinge 13 with blowing out unit 3, like this, can open wide blowing out under the state that hangs down with front lower unit 3 at indoor unit.

The state of the indoor unit of Fig. 2 (b) when being depicted as air-conditioner operation, make the air conditioner entry into service in case open the power supply of indoor unit, so as shown in Figure 1, the wind deflecting plate up and down 12 that blows out unit 3 rotates to position e from position d, blows out wind path 10 and is just opened wide.Then, pressure fan 8 rotates from upper air intake panel 5 room air is sucked the indoor unit, removes airborne dust by air cleaner 6, regulates the temperature and humidity of the room air that sucks by heat exchanger 7a～7c.Room air after the adjusting, the pressure fan 8 of flowing through are sent to and blow out wind path 10, air stream left and right sides wind deflecting plate 11 and up and down wind deflecting plate 12 be partial to, become and removed the air that dust regulates temperature and humidity and be blown to indoor again.By this room air is flowed repeatedly, the daily life place is adjusted to the state that is suitable for living.

Fig. 2 (c) is depicted as other states of the indoor unit when the running air conditioner.Do first the state when turning to position b for the front panel 4 that makes indoor unit from position a shown in Figure 1 under this situation.

Like this, keep the state that opens wide owing to making front panel 4 turn to position b from position a, therefore, form an air suction inlet 15 in front between plate 4 and the casing, if make air-conditioner operation in that front panel 4 is opened wide under the state that is in position b, then room air also can be inhaled into from this air suction inlet 15.

With reference to Fig. 3 this is illustrated, room air is not only from the upper air intake panel 5 shown in the solid arrow, and also the air suction inlet 15 that can form from front panel 4 upper portion that are open in position b is inhaled into according to direction shown in the dotted arrow.

So, being configured near the dish 9 that uncovers, and only by among the not smooth heat exchanger 7a of upper air intake panel 5 its indoor air flows, also shown in dotted arrow, the air capacity of the heat exchanger 7c that flows through also increases to some extent, just increases with respect to the whole 7a of heat exchanger～7c amount of air drawn.Therefore,, bring into play the function of heat exchanger 7a～7c effectively, can improve the heat exchanger effectiveness of heat exchanger 7a～7c integral body by the heat exchange amount increase of heat exchanger 7a～7c exchange.Its result, the cooling and warming ability of air conditioner increases, and therefore, it is suitable for making at short notice the daily life place to regulate the situation that cooling is heated rapidly.And, even front panel 4 is in position b, when the daily life place looks up indoor unit, owing to blocking of front panel 4 be cannot see the inside of indoor unit, so the attractive in appearance of design that can not disfeature.

In addition, in this embodiment, owing to focus on appearance design attractive in appearance of indoor unit for air conditioner, and be not have concavo-convex platen surface with the surface design of front panel 4, but as shown in Figure 4, by the bottom of plate 4 in front bottom air suction inlet 16 is set, even in front under plate 4 closing state, according to direction shown in the dotted arrow, can suck room air from the bottom air suction inlet 16 of front panel 4, and the indoor air stream that can make suction is configured near the heat exchanger 7a of dish 9 that uncover and carries out heat exchange, thus, also can improve the performance of air conditioner.

If air conditioner turns round for a long time; then illustrated as the front; air cleaner 6 is the parts of the dust that is used for removing room air; dust is put aside the circulation that is unfavorable for room air on the surface of air cleaner 6; make that (soakage that is the room air that carries out heat exchange of heat exchanger 7a～7c) reduces heat exchanger 7, and its result will influence the efficient of air conditioner.In addition, as if remaining in operation under the state of in air cleaner 6, having put aside dust, then not only influence the efficient of air conditioner, the dust that not having on the air cleaner 6 removed enters the inside of indoor unit, and be attached on the heat exchanger 7, the heat exchanger effectiveness of heat exchanger 7 is reduced, thereby the performance of air conditioner is reduced.

In order to prevent above-mentioned situation, be necessary regular cleaning air filter 6, as the explanation in the above-mentioned conventional example, because the indoor unit of air conditioner is arranged on the eminence of indoor wall near ceiling, for cleaning air filter 6, the operator has to stand in pedal or two-sided ladder is first-class, goes down to take air cleaner 6 in unsure state.

That is, in above-mentioned prior art 1 shown in Figure 14,, make the front panel 51 that is positioned at air cleaner 50 face side parallel mobile, and air cleaner 50 can be taken to the front lower of indoor unit by bindiny mechanism 52.But in order to make front panel 51 parallel moving, it is outstanding to standing in the first-class operator who plays pendulum of pedal or two-sided ladder in the last stage.The operator who stands on narrow pedal or the two-sided ladder is difficult for avoiding outstanding like this and front panel 15 that come.

Also have in above-mentioned prior art 2 shown in Figure 15, take the occasion of air cleaner 60 at needs, front panel 61 is installed at its back under the state of air cleaner 60 carried out backward rotation, while is in the front lower of indoor unit, air cleaner 60 front panel 61 hung down, so that will be in nearby.At this state,, therefore can take this air cleaner 60 easily because air cleaner 60 is positioned at the nearside of the front panel 61 of reducing to the below.

But in this occasion, front panel 61 also rotates to standing in the first-class operator who plays pendulum of pedal or two-sided ladder.When this rotates, owing to front panel 61 is not applied brake force, front panel 61 is approaching because of inertia force rotates hastily to the head or the face that stand in pedal or the first-class operator who plays pendulum of two-sided ladder, can not eliminate the sense of insecurity when opening wide front panel 61.

In the present embodiment, can be safely and easily win the operation of air cleaner 6 and the cleaning of cleaning and heat exchanger.

Promptly, the operator stands on pedal or the two-sided ladder etc. in the present embodiment, under labile state for when taking air cleaner 6 and open wide front panel 4, as illustrated in fig. 1, it or not the front panel 4 that quickly opens wide the indoor unit face portion, and be to use diaxon to connect hinge 14 as this rotating mechanism, front panel 4 is rotated in two stages, (promptly first rotate) is making inertia from body weight and rotate according to front panel 4 in initial rotation, but after this first rotation is carried out, produce brake force and the rotation of front panel 4 is temporarily stopped, further opening wide from this state second of front panel 4 rotates, needing the operator to resist this brake force and rotate and it can not be rotated because of inertia.Thus, can eliminate the sense of insecurity that operator when winning air cleaner produces for the rotation of front panel 4.

That is, among Fig. 1, in first rotates, make to standing in pedal or two-sided ladder etc. and go up the operator's (not shown) who under labile state, wins air cleaner 6 head or the front panel 4 that face rotates, temporarily stop at position b, like this, front panel 4 can not run into operator's head or face.In addition, front panel 4 is further turned to second rotation of position c from position b, front panel 4 will be outstanding to the operator, but in this second rotation, because rotation has been applied brake force, make that front panel 4 can be because of inertia force rotation rapidly.

As above, front panel 4 temporarily stops at position b when making its rotation, therefore, can be not approaching rapidly towards the operator who wins air cleaner 6, can not attack this operator's head or face directly.Also have, in first rotates, do not apply brake force, therefore can reduce to be fastened at first the power that the front panel 4 on the trim main body 2 draws back from trim main body 2.In addition, in order further to open wide front panel 4 from the state that temporarily stops at position b, the operator can push the part (for example upper end) of the outstanding front panel 4 of indoor unit according to the idea of oneself, the operator is recognizing that front panel 4 pushes front panel 4 under the situation of self giving prominence to, therefore can make front panel 4 be open to position c relievedly.Also have, when second rotates, front panel 4 is rotated, therefore, front panel 4 is can be not rapidly not side-prominent and drop down onto the front of indoor unit rapidly to operator one, can carry out the unlimited operation of front panel 4 relievedly.

According to above explanation, in the time of on slide plate 32 being installed to slide plate supporting 28, embed optionally according to the protuberance 33a on the elastomer 33 that is arranged on slide plate 32 among recess 29a, the 29b of slide plate supporting 28 that any one is such, slide plate 32 can slide to arrow A-A ' direction.In case the slide plate 32 that is installed in the slide plate supporting 28 is slided to the arrow A direction, the protuberance 33a of elastomer 33 just embeds the recess 29b (fastening) of slide plate supporting 28, if to arrow A ' the direction slip, then the protuberance 33a of elastomer 33 just embeds the recess 29a that slide plate supports 28 opposites, one side.In addition, embed at the protuberance 33a of elastomer 33 under the state of recess 29b of slide plate supporting 28, the turning cylinder 34 of slide plate 32 sides becomes the state (to call the state that draws in that this state is a turning cylinder 34 in the following text) that moves to the arrow A direction, under the state of the recess 29a that embeds slide plate supporting 28, the turning cylinder 34 of slide plate 32 sides becomes to arrow A ' state (to call the outstanding state that this state is a turning cylinder 34 in the following text) that moves of direction.

Diaxon connect hinge 14 be with constitute tabular bear axle 18, from this bear axle 18 at grade roughly the linking part 17a that extends of U word shape, bear that axle 18 straight line on perpendicular to the direction of this face extends and constituted with the linking part 17b of roughly U word shape extension and the 21a of bearing portion, the 21b that are separately positioned on the front end of 17a, 17b equally from this from its front end and linking part 17a.Here, the U word shape that roughly is of so-called linking part 17a and linking part 17b partly is meant each other on same direction the curve that roughly is the U word shape with same shape and size formation, and these are formed at the 21a of bearing portion, 21b last set dead eye 22a, 22b on linking part 17a, the 17b respectively on same straight line.These dead eyes 22a, 22b are respectively the through holes that inserts turning cylinder 27.

Also have, in bearing portion 18, be provided with circular dead eye 19 and be communicated with it cut hole 20, this dead eye 19 be the through hole of turning cylinder 34 usefulness on the slide plate 32, cuts hole 20 and be the through hole with projection 35 usefulness of these turning cylinder 34 one.

On the other hand, the screw of torque bearing 23 usefulness insertion screw hole 24 (not having diagram) is fixed on the not shown trim main body 2.On this torque bearing 23, have and have the bearing portion 25 that makes by the dead eye 26 of turning cylinder 27.

It is such according to making the 21a of bearing portion, 21b clamp the bearing portion 25 of torque bearing 23 that diaxon is connected hinge 14, be installed on this torque bearing 23, by turning cylinder 27 is inserted dead eye 22a, the 22b of the logical 21a of these bearing portions, 21b and the dead eye 26 of bearing portion 25, make this diaxon connect hinge 14 and become one with torque bearing 23.At this moment, the two ends of turning cylinder 27 are fixed on the 21a of bearing portion, dead eye 22a, the 22b of 21b that diaxon connects hinge 14, also have, and turning cylinder 27 can make dead eye 26 inner rotation of the bearing portion 25 of torque bearing 23 with big frictional force.Promptly, such as mentioned above, connecting hinge 14 at diaxon is installed under the state on this torque bearing 23, if making this diaxon connection hinge 14 is that rotate at the center with the bearing portion 25 of torque bearing 23, turning cylinder 27 is fixed on diaxon and connects among dead eye 22a, the 22b of the 21a of bearing portion, 21b of hinge 14 so, therefore, when diaxon connects hinge 14 rotations, drive dead eye 26 inner rotation of the bearing portion 25 of torque bearing 23, and the frictional force by dead eye 26 becomes the rotary action brake force that diaxon is connected hinge 14.Thus, follow the rotation of brake force promptly to become above-mentioned second rotation.

As mentioned above, connecting hinge 14 at diaxon is installed under the state of this torque bearing 23, the turning cylinder 34 of the slide plate 32 that becomes one slidably in the slide plate supporting 28 with front panel 4 connects the dead eye 19 of the bearing portion 18 of hinge 14 at diaxon, the projection 35 of its turning cylinder 34 is embedded respectively cutting hole 20 equally, and front panel 4 just can connect hinge 14 by diaxon and be installed on the trim main body 2.At this moment the protuberance 33a of the elastomer 33 of slide plate 32 embeds slide plate and supports the arrow A on 28 edges ' the recess 29a of direction.

In this state, catch the claw 36 of slide plate 32 that slide plate 32 is slided to arrow A one side, if make the protuberance 33a of the elastomer 33 of slide plate 32 embed the recess 29b that slide plate supports 28 another sides, then the turning cylinder 34 of slide plate 32 connects the dead eye 19 of the bearing portion 18 of hinge 14 from diaxon, the projection 35 of this turning cylinder 34 is equally from cutting hole 20, respectively outwards outstanding, the slide plate 32 of the both sides, bottom by operation front panel 4 is operated, and front panel 4 can be taken off from trim main body 2.Front panel 4 is being installed under the situation of trim main body 2, is operating getting final product in contrast to this.

The turning cylinder 34 of slide plate 32 is in the dead eye 19 of the bearing portion 18 of diaxon connection hinge 14, the projection 35 of this turning cylinder 34 is being cut under the state that hole 20 embeds respectively equally, because with the dead eye 19 of cutting hole 20 is the thickness of the length (hereinafter referred to as the length of cutting hole 20) of the circumferencial direction at center greater than the projection 35 of turning cylinder 34, therefore, be equivalent to the length after this cuts the thickness of length deduction projection 35 in hole 20, thereupon, turning cylinder 34, front panel 4 is that the center is free to rotate with the dead eye 19 that this turning cylinder 34 embeds.This makes can realize the first above-mentioned rotation.

Below, according to Fig. 6～Fig. 9 the rotational action of front panel 4 is described.

As shown in Figure 1, and illustrated with Fig. 5, and front panel 4 is to connect hinge 14 by diaxon to be installed in rotation on the trim main body 2.And, diaxon connects hinge 14 as shown in Figure 6, have bearing portion 18 that front panel 4 is connected rotationally and diaxon is connected hinge 14 and is attached at the 21a of bearing portion on the trim main body 2 rotationally, these bearing portions 18,21a link together by the linking part 17a that U font roughly forms.Be provided with the dead eye 19 that supports the turning cylinder 34 that becomes fulcrum when front panel 4 rotates and support the fan-shaped that is arranged on the projection 35 on the turning cylinder 34 and cut hole 20 in bearing portion 18.Turning cylinder 27 inserts the bearing 21a of portion and also is fixed, and thereupon, diaxon connects hinge 14 and is fixed, and therefore is connected hinge 14 with diaxon and becomes one and rotate.

Roughly the linking part 17a that forms of U word shape ground forms that can be positioned over the 21a of bearing portion be between the circular arc f and circular arc g at center, as Fig. 7 and shown in Figure 8, rotate if make diaxon connect hinge 14, then linking part 17a just can rotate in the narrow range between these circular arcs f and the circular arc g.And, diaxon connects hinge 14 and forms roughly U font, therefore, turn to from position b under second situation of rotating of position c, near the direction β 1 of the rotational angle the 22a of bearing portion of diaxon connection hinge 14, as shown in Figure 8, at the leading section of U font bending roughly, can be to rotational angle β 2 conversion direction of rotation.

Also have, as shown in Figure 8, can make to be connected the leading section 10b on the 10a above the wind path that constitutes the top wall that blows out wind path 10, the U font that constitutes to the linking part 17 that roughly is the U font is inner outstanding, thereby cover the 21a of bearing portion, therefore, just can make and cannot see the 21a of bearing portion from the daily life place.

Comprehensive various result, the actuating range that can make the diaxon of U font roughly connect hinge 14 be limited in the circular arc f among a small circle in, simultaneously the actuating range of linking part 17a is confined in the narrow range of circular arc f and circular arc g.In addition, because the interval h that can make front panel 4 and blow out between the front end 10b of top 10a of wind path 10 diminishes, therefore, the appearance surfaces that can make front panel 4 and the top front end 10b that blows out wind path 10 and be connected with wind deflecting plate 12 up and down couples together sleekly, can make the aesthetic feeling of the lucid and lively raising outward appearance of appearance and modeling.

In addition, in the occasion of closing unlimited front panel 4, as shown in Figure 9, front panel 4 is being positioned at position c and under the state that the front lower of indoor unit hangs down, opposite when unlimited, be equivalent to first rotation of rotating (from position c rotational angle α to position d), then, be equivalent to second rotation of rotating to position a.

As mentioned above, in the present embodiment, open wide front panel 4 and its front lower at indoor unit is under the state (promptly being arranged in the state of the position c of Fig. 8) that hangs down, in Fig. 5, if slide plate 32 is slided to the arrow A direction with claw 36, thereby the protuberance 33a that makes elastomer 33 moves to the recess 29b of slide plate supporting 28, so, because the turning cylinder 34 of slide plate 32 connects the dead eye 19 of hinge 14 from diaxon, the projection 35 of turning cylinder 34 is outwards outstanding respectively from cutting hole 20, therefore, can connect hinge 14 from diaxon and open wide front panel 4, take off front panel 4 from trim main body 2.

Also have, when second rotates, apply brake force front panel 4 can be stopped at an arbitrary position, move to recess 29b side, just can take off front panel 4 in this position by make slide plate 32 in this position because front panel 4 rotated.Therefore, even do not open wide front panel 4 to maximum, owing to be to rotate the easy-operating position of range content that allows second to take off front panel 4, thereby can improve security and operating efficiency.

In the present embodiment, the shape of diaxon connection hinge 14 roughly forms and is the U font, in first rotates, be rotating fulcrum to embed the turning cylinder 34 that diaxon connects the dead eye 19 of hinge 14, front panel 4 can freely be rotated, in second rotates, connect the turning cylinder 22 of hinge 14 as rotating fulcrum with diaxon, make it rotatable when front panel 4 is applied brake force on one side down with the state that is connected hinge 14 one with diaxon, make front panel 4 to open wide and to hang down in the front lower of indoor unit near 180 °.

Here, when first rotates, owing to do not apply brake force, can reduce the front panel 4 that is fastened on trim main body 2 in order to open, and the power that front panel 4 is drawn back from buckling parts.Also have, because front panel 4 temporarily stops at assigned position (position b), front panel 4 just can not run into the operator's who opens it head or face.

Also have, when second rotated, owing to applied brake force, front panel 4 can be not outstanding to the operator that it is opened suddenly.And, in unlimited front panel 4, owing to be under the situation that operator oneself recognizes, to press front panel 4, so even front panel 4 is side-prominent to operator one, owing to recognize the outstanding of it, the operator is safe, and the operator is worried about.Because front panel 4 can stop when second rotates at an arbitrary position, therefore, even can not open wide front panel 4 safely, also can win in the position of conveniently winning operation.

Also have, roughly be the U font in order to make diaxon connect hinge 14, when second rotates, as shown in Figure 9, the 21a of bearing portion that diaxon is not connected hinge 14 has been exposed in the habitat environment, owing to the leading section 10b that exceeds that makes leap blow out wind path 10 gives prominence to, therefore, can cover the front face that diaxon connects the 21a of bearing portion of hinge 14, the attractive in appearance of moulding can not disfeature.

Moreover when making front panel rotate nearly 180 ° angle with a fulcrum like this, the front panel 4 after opening wide turns to the reverse side with respect to 180 ° of rotating fulcrums, has to make the component shape of the front panel part in the contact slewing area to change greatly.For example, as shown in Figure 10, must make the width stenosis of wind deflecting plate 12 up and down narrow, its rotational angle is diminished.Under the narrow situation of the width stenosis of wind deflecting plate 12 up and down, just can not regulate temperature and humidity is partial to the wind that blows out from indoor unit fully, reducing the occasion of rotational angle, front panel 4 does not hang down in the bottom of indoor unit and comes out towards operator's a pleurapophysis, has the problem of secure context.Also have, around the rotating fulcrum 38 that front panel 4 is rotated, make it can not become the obstacle of rotation, will greatly impair the attractive in appearance of appearance and modeling owing to must open wide.

As described above, although the operator stands in operation on narrow and small unsettled pedal or the two-sided ladder, also can open wide front panel 4 safely, also have, owing to just can win front panel 4 simply by slide plate 32 is slided, so the air cleaner that can remove dust in the room air and pull out dirty easily, the air cleaner that makes dirty cleans easily.

In addition, if air conditioner turns round for a long time, so because heat exchanger 7 grades also can dirty dirt, in order to keep the performance of air conditioner, also must cleaning heat exchanger 7 etc.

In prior art shown in Figure 16 3, air cleaner 70 is divided into front face and last facial two parts, the air cleaner of face portion pulls out from the space of front panel bottom, last facial air cleaner 70 pulls out together and is removed at lower and upper air intake panel 71 of the state that is installed on upper air intake panel 71, respectively cleaning air filter 70 and upper air intake panel 71.In addition, carry out the cleaning of heat exchanger from the space of indoor unit opened upper end.

But, if constitute like this, then the air cleaner 70 in the face of upper air intake panel 71 just becomes two different parts with the air cleaner of facing front panel, not only can increase the number of parts, also can increase the number of the mould of making air cleaner, will make the price of goods raise, also have to clean respectively these two air cleaners simultaneously, reduce the efficient of washing and cleaning operation.

In addition, in the operation that air cleaner 70 and upper air intake panel 71 are taken out together, also there is this situation, because upper air intake panel 71 is at the topmost of indoor unit, therefore when upper air intake panel 71 is pulled out, even the operator climb to foot-operated or two-sided ladder above, owing to cannot see the operation of hand, even being slided, upper air intake panel 71 pulls it, neither a nothing the matter.

With respect to this, in the present embodiment, air cleaner 6 portion and last face in front forms as one, provides a kind of the number of parts few and make that the required mould of air cleaner tails off, manufacturing cost reduces, washing and cleaning operation also is easy to indoor unit thus.

In addition, in the present embodiment, as shown in figure 11, the facial guide rail of being formed by following side rails 39a and last side rails 39b 39 that is provided with on the indoor unit casing, by making upper air intake panel 5, just can carry out the installation and the taking-up of upper air intake panel 5 sliding between side rails 39a and the last side rails 39b down.In addition, in the proximal end of this guide rail 39, casing front (that is, the indoor daily life place) side on following side rails 39a is provided with outstanding jut 39c downwards when tilting.Therefore, upper air intake panel 5 is under it is installed in state on the guide rail 39, and its part makes the end of its casing face side towards the below on jut 39c.

Here, shown in Figure 12 (a), when opening wide front panel 4, the front face of upper air intake panel 5 just exposes in the front of indoor unit, even under the occasion that upper air intake panel 5 is pulled out, shown in Figure 12 (b), also can under the situation of visible manual work, carry out operation.In addition, though air cleaner 6 can take out under the state of unlimited front panel 4 only, shown in Figure 12 (c), because if front panel 4 and upper air intake panel 5 are taken out, then the two sides of the front face of indoor unit and last face is opened wide, and makes air cleaner 6 also be removed easily.And because the front face of indoor unit and last facial two sides are all opened wide, therefore cleaning heat exchanger 7 also becomes simple.

In addition, under the upper air intake panel 5 that will take off is installed to situation on the decorative panel main body 2, as shown in figure 11, protuberance 39c is outstanding to the indoor when side rails 39a tilts downwards down from guiding rail 39, and top at this protuberance 39c, because side rails 39b is not set, therefore, the leading section of upper air intake panel 5 directly can be placed on this protuberance 26c from top, like this, only need push its leading section is stated from down upper air intake panel 5 on the side rails 39a, just upper air intake panel 5 correctly can be installed on the guiding rail 39 and be set to assigned position.And, when as above being installed to upper air intake panel 5 on the guide rail 39, as illustrated, can open wide or take out front panel 4 with Figure 12, therefore can under the situation of visible manual work, press and give as security upper air intake panel 5, thereby can carry out installation exercise relievedly.

In addition, even owing to push insufficient and upper air intake panel 5 is not installed under the situation of assigned position fully, in case front panel 4 is closed, then because its front end can be pushed into upper air intake panel 5 position of regulation always, therefore, can not make air conditioner not have to turn round under the complete mounted state at the upper air intake panel.

Here, as shown in figure 11, front end face is provided with elastomeric element 40 in the indoor of upper air intake panel 5, as mentioned above, upper air intake panel 5 is being installed, when front panel 4 was in position a (Fig. 1), the leading section of the front end of front panel 4 and upper air intake panel 5 just contacted by elastomeric element 40.Therefore, even the small vibration when turning round because of indoor unit causes upper air intake panel 5 to vibrate between guide rail 39, thereby these vibrations yet can not absorbed and can make a noise by elastomeric element 40.
