The preceding grid 24 of indoor assembly 12 is provided with a device for filtering indoor air 348, illustrates in Figure 36 to 38.Before describing filter 348 in detail and how it to be installed in, indoor grille 24 will at first be described after on the grid and how it be installed on the indoor shell 44.Referring now to Figure 27 to 31, preceding grid 24 comprises a front portion 302 that is the plane substantially, and the front portion comprises that air inlet screen 22 and is equipped with the perforate 304 of room air Exhaust assembly 26.Anterior 302 also comprise a rectangular substantially perforate 306 that is fit to lay control cabinet assembly 182 when being installed to grid 24 on the aircondition.

What stretch out in the front portion 302 on plane is respectively upper wall 308, lower wall 310, left side wall 312 and right side wall 314.The protective cover spare that upper wall, lower wall and left and right sides wall be common to be constituted that an integral body forms and extend back from the planar front portion 302 of grid 24.It will be appreciated that Figure 27 is the back side that air inlet grid 24 is shown.Left side here and right side are according to seeing air conditioner unit and grid 24 from front portion shown in Figure 1, and be therefore, opposite with Figure 27 to 31.

Now see Figure 28, the inwall 316 of the 24 right walls of grid shown in the figure.On this inwall integrally formed be a pair of horizontal expansion exceed structure 318, its each form forward-facing a plane 320

With reference to Figure 30 and 31, the inwall 32 of left wall 312 is provided with the pawl integrated structure 324 of a horizontal expansion.This pawl integrated structure 324 constitutes a flat seal face 328 forward-facing.

Preceding grid 24 is suitable for being directly installed on the fit structure that is arranged on the indoor shell 44.With reference to Figure 10,11 and 12, the right wall 54 of indoor shell 44 is provided with the grid that separates of a pair of integral molded plastic extension 330 is installed.Each extension extends towards the place ahead, inside of wall 54, and a longitudinal extension perforate 332 is set, this perforate is fit to be contained in and exceeds structure 318 on the right wall of grid, and wall 320 is forward-facing combined with the 332 interior mating surface work of plane relativeness and groove.

Be fit to hold the pawl mechanism 334 that forms on left wall 52 inboards at indoor shell 44 at the pawl compressing structure 324 on the left wall 312 of grid.This pawl mechanism illustrates the most clearly in Figure 11,12 and 15.Pawl 334 comprises one and shell 44 integrally formed elastic arms 336.This arm 336 stretches out from standing part 338, and extends towards the other places to the outer end 340 that comprises a backward-facing seal face 340, and this seal face 340 is fit to combine with the seal face forward-facing 328 that forms on grid 24 left side walls when grid is installed.Pawl comprises an inclined plane 342, this inclined plane be fit to help grid 24 combine with shell 44 with convenient grid and shell move into work in conjunction with the time make the pawl deflection.

Can realize indoor grille 24 is installed on the shell 44 by locating indoor grille shown in figure 32 like that.As shown in the figure, two on the right wall of grid exceed structure 38 and combine with cooperating perforate 332 and extension 330 work are installed.This combination provides a pivotal point, and this pivotal point is fixed also the right side of grid and can be moved pivotally so that move towards indoor shell 44 in the left side around its.The grid left side continues to move towards compressing structure 324 makes inclined plane 342 combine with compressing structure 324, be that elastic arm curves inwardly till grid moves into desired installation site backward then, at this moment, the end 338 of pawl 334 moves and faces antetheca 328 and enters reliable connection, thus, make preceding grid 24 be connected in shell 44 reliably.

With reference to Figure 15, it is to realize by the hole of a small tool (not shown) being passed on the left side wall 52 that is arranged on the shell 44 adjacent with elastic arm 336 344 that grid unloads shell.The power that is applied on the instrument curves inwardly elastic arm, thus release piece mechanism 334.In order to prevent the fracture of elastic claw arm, holistic stop surface 346 advances shell 44 at the back of pawl integral molded plastic.Elastic arm 336 combined with stop surface 346 before reaching breakaway poing, can prevent the unexpected fracture of elastic arm thus in unloading the grid process.

Referring now to Figure 33 to 38,, a filter assemblies 348 is set for the room air at the inlet hole 22 of the indoor grille 24 of flowing through filters it before flowing to evaporator coil 18.Filter comprises a rectangular substantially frame 350, and it constitutes a crooked grid-like part 352.The horizontally extending antetheca 354 that faces is formed at the top of filter frame 350, but this wall has a pair of pawl structure 356 that is press-fitted fast that is arranged on the manual release on its opposite end.Filter frame 350 the most handy a kind of no filler co-polymer polypropylene (unfilledcopolymer polypropylene) are made.A kind of screen pack material 358 covers and the whole part that constitutes grid 352 that is connected in.Preferably a kind of polypropylene material of this net also is fit to vacuum and/or process of washing it be cleaned, and like this, screen pack can re-use in phase device lifetime.

Filter 348 is fit to be placed in the horizontal-extending hole 360, and this hole is arranged on the import screen 22, on the import grid 24 of its upper end.As shown in figure 34, filter is fit to insert in the notch 360 with the side 362 that bends outwards in the face of device 10 back sides.When filter passed notch, dorsal part 362 directly was attached on the evaporator coil 18 and slides, and filter is laterally guided by the sidewall 364 that the inwall from grid 24 stretches out.When inserting fully, whole covering evaporator coil of filter and wall 354 cover the hole, thereby form the part of the front surface of grid 24.

When being mounted, the fit structure engagement on pawl mechanism 356 and the lower limb that is arranged on horizontal notch 360 now will be described.Pawl mechanism on screen pack 356 each comprise one with filter frame 350 integrally formed to front upper place elastic claw 366.The free end 368 of pawl is fit to combine with the little horizontal-extending notch 370 that forms on the lower wall 372 of horizontal notch 360.On the wall 372 that is arranged on adjacent to each pawl 366 and a semi-circular recesses 374 cooperating deep-slotted chip breaker 376 to form on the filter wall 354 adjacent to horizontal notch 370.

Therefore, when being installed to filter on the air-conditioner as mentioned above, the elastic claw 366 in filter is will be backward crooked, like this, the free end 368 of pawl just on the lower wall 372 of notch in conjunction with horizontal notch 370.This makes filter remain on its operating position reliably.When requiring to take off cleaning filtration, the free end 368 of pawl is handled and is made the horizontal notch 360 of their disengagings under the dynamic pressure owing to the deep-slotted chip breaker 374 and 376 around them can pass through easily.Simultaneously, deep-slotted chip breaker 374 is as the handgrip that filter 348 is manually unloaded notch.With reference to Figure 37, can see that the upper wall 354 of filter frame 350 is asymmetric.Upper wall can be consistent with the antetheca of grid to cover notch before this made, and notch is shifted to the left side of the preceding curved wall of grid 24.

As the front has briefly explained about the description of control cabinet 182, the knob 296 that is fit to be attached on the axle 228 of gauge tap 184 and 186 is the parts that are injected into a whole, and without any need for additional inserts or clip or similar structures with the axle 228 that is connected with them combination of working reliably.In this preferred embodiment, control knob 296 is to be injection molded into a kind of ABS plastic material.

With reference to Figure 44 to 49, knob is circular, has the planar section 377 that bigger the stretch out structure 378 of a pair of quilt on its outside separated, and the described structure that stretches out is fit to make knob with grasped.This structure is stretched out from the large-size on the one end 380, dwindles gradually to 38 reduced size in the middle, expands original large-size to then on its opposite side 384.This structure comprises an outer wall 386 and a pair of from the curved wall of outer wall 386 to the expansion of one of planar section 377.

The back of knob 296 is provided with a big groove 390, and its shape is basic consistent with the structure 378 that stretches out on the knob upside.Specifically, groove has one what be that the relative groove of lower wall 392 390 central authorities of the outer wall 386 and the opposite side of crooked sidewall 394 (they are inwalls of the crooked sidewall 388 of structure 378) are provided with is one to constitute the axle support structure 396 in D shape hole 398.Axle support structure 396 and the D shape hole 398 on it are divided into two spaced portions by vertically extending notch 400. each separate section of axle support structure and curved sidewall 394 whole formation, represent with label 402.

With reference to Figure 45,46 and 47, can see that this D shape hole 398 is injection moulded into to fall back to pull out the angle.This makes at the hole cross-sectional area on the outer end 404 less than the cross-sectional area on its lower end 406.Size in the hole 404 of upper end is such, even can just hold wherein at the tapering point of the axle shown in Figure 48 and 49.

The thickness of curved wall 388/394 will form like this, and promptly when the upper end 404 of axle 228 being inserted D shape holes, and the shaft portion 410 of overall dimension is when inserting wherein, D shape hole with at 402 places the whole arcwall part 388/394 that is connected with outwardly-bent.This just makes the cross section in hole 298 increase, thereby allows the whole insertion of axle.The result is that in case knob is installed on the axle 288, the separate section in wall 388/394 and D shape hole just tries hard to reply its not deformation state, thereby strong bonded is on the whole dimension part 410 of axle 228.

Can see that upwardly extending backstop 412 injection mouldings are advanced the lower wall 392 of groove 390 so that stretching into of axle is limited on the desired position.Also should further recognize, the thickness of the planar section 377 that the thickness of curved wall 388/394 is connected with these walls is very important for allowing above-mentioned desired deflection. such thickness selects can be determined by the person skilled in the art fully, this will depend on material therefor, spool size and other variable factor and changing.

After indoor assembly 12 and outdoor assembly 14 assembled, what aircondition 10 will be described below was used to collect condensate liquid of being removed by the humid air path by evaporator coil 18 and the system of condensate liquid being drawn go back to outdoor assembly 14 back.Now see Figure 24 to 26, can recognize that the lower extension 150 that plays the volute sealing cover 90 of the lower reaction that evaporator coil 20 is installed also can be used as the condensate discharge dish of evaporator coil during as room air conditioner in this system.As shown in Figure 5, cylindrical shape outlet 588 is arranged on the bottom of volute sealing cover 90, is communicated with discharge plate 150 fluids.

When the inner timesharing in assembly room, the outer end that these cylindrical shape outlet 588 covers imbed vast sky core barrel 72, this pipe is the rear wall 46 that indoor shell is advanced in injection moulding, as described above and shown in Figure 11 and 12.With reference to Fig. 3, the condensate discharge pipe is drawn and is communicated with the structure 590 of accepting around the hole 592 on following outdoor housing 40 antethecas 580 from the rear wall 46 of indoor shell 44, shown in Fig. 2 and 3.Be tightly connected in order to ensure fluid, apply a suitable sealant around the cover scarf joint.

Continuation is with reference to Fig. 3, and hole 592 is communicated with condensate liquid runner 594 in the whole lower wall 414 that is formed at housing parts 40.This runner is to be made of a pair of vertically extending substantially parallel wall 596 and 598, and stretches to wall 510 backward usually.It stretches at the parallel with it passage 600 in condenser coil 28 back to the bottom right around the end of wall extension 538 then.Preferably blow to condenser coil 28, to improve the efficient of system by will the flow through water of passage 600 of the effect of outdoor fan 30.Any unevaporated condensate liquid in effect back just continues to flow to the left end of passage 60 like this, and discharges from lower house 40 by cylindrical shape outlet 602.

It should be understood that above-mentioned condensate liquid removal system is just in order just to work effectively during as room air conditioner at aircondition 10.To illustrate below when with aircondition as a separation system and volute sealing cover 90 performances during with anti-dress the in indoor assembly 12 top and the bottom as the condensate discharge gatherer.

Another characteristics of metal chassis 16 are to help by a suitable rectangular opening 604, for example on a wall or hole that has on the window of suitable dimension, the ability of the device 10 that easily installs an air-conditioner.Referring now to Figure 64 and 50, the open forward end on chassis is provided with an integrally formed directed flange 606 of vertically extending downwards.In case form perforate 604, just the assembly of indoor assembly 12 and outdoor assembly 14 can be unloaded metal chassis 16 by the screw that unloads on the tab 582 that protracts with suitable dimension.By the directed flange 606 that combines with sidewall 608 chassis 16 is positioned in the hole 604 then around hole 604.The supporting frid 610 that a pair of diagonal angle extension of aircondition 10 will be set then is installed on the side surface 612 of chassis 16 and perforate 604, thus chassis 16 accurately is aligned on the optimum position of supporting aircondition 10.

Continuation is with reference to Figure 64, and each diagonal angle frid 610 is to make with a kind of structural steel and iron, and it comprises that one is formed with the longitudinal extension part 614 of a plurality of ribs 616 on it.The outer end of each frid 610 comprises that one curves inwardly to be arranged at below the chassis 16 and its lower flange of structure support.The lower end of longitudinal component 614 is provided with a hole 620, and it axially aligns with the mating holes 614 that is arranged on the sidewall 576 and 578 on chassis 16.Suitable threaded fastener (not shown) passes hole 620 and 622, so that supporting member 610 is connected in chassis 16.

The upside of the longitudinal component 614 of frid is provided with the aligned tabs 624 that bends outwards.If the length of diagonal angle supporting frid 610 like this, promptly when supporting member being connected in chassis (as mentioned above) and aligned tabs 624 in conjunction with sidewall 608, chassis 16 is on the best orientation of the installation of aircondition and work.Therefore, in case aligned tabs combines with wall 608, will penetrate according to the suitable fasteners that the material of sidewall 608 is determined in the hole 626 that is arranged on the longitudinal component of frid and surface 612 sidewall 604 facing 614.

After the mounting support structure, shown in Figure 64, can easily make the aircondition 10 that assembles slip into chassis 16, attachment screw is reconnected tab 582, thus air-conditioner be remained on the operating position.Device is plugged in, open, just can obtain the effect of cooling off and drying.

As previously mentioned, the combining structure of aircondition 10 can make indoor assembly 12 and outdoor assembly 14 be installed separately into the air-conditioner of a split type system.A kind of like this mounting structure is shown in Figure 65 and 66.

At first,, can see not having screen to be arranged on the sidewall 630 of lower house 40 about outdoor section.One hole 632 is set to replace screen, it provides refrigerant pipe and electric wire (totally by label 634 expressions) path.Illustrated tubes and electric wire are to pass outer wall 636 and be communicated with indoor assembly 12, and indoor assembly is mounted near its top 640 the inwall 638.

It may be noted that the indoor assembly 12 when split type system applies is that above downward mode is installed, locate mode is opposite when being applied in room air conditioner with indoor assembly 12.Such installation can allow to press arrow 642 by the room air floss hole 26 on the housing lower end and discharge air, and this is traditional mode for split type system air conditioner.In addition, be in control handle 296 on the lower end because high wall mounting arrangements and easier use.It will be appreciated that the remote control that device can be provided for controlling, this control device can be installed in the correct position of control cabinet 182 and can be handled by the remote controller that prior art is familiar with.

As above describe in detail, all systems of indoor assembly all are designed to and can opposite direction work effectively.
