As Fig. 3 and shown in Figure 5, be provided with limit switch 110L in the end of the position of readiness H1 of guide rail 52L side, be provided with limit switch 110R in the end of the position of readiness H1 of guide rail 52R side.These limit switches 110L, limit switch 110R detect the switch whether cleaning brush unit 51 is positioned at position of readiness H1, its have housing section 111L, 111R and certainly this housing section 111L, 111R to dust shift position H2 side-prominent switch portion 112L, 112R.When cleaning brush unit 51 was positioned at position of readiness H1, switch portion 112L, the 112R of limit switch 110L, 110R together were pressed and become on-state (state shown in the double dot dash line of Fig. 7); When cleaning brush unit 51 was not positioned at position of readiness H1, the pushing of switch portion 112L, 112R was released and becomes off- state.Limit switch 110L, 110R are connected with aftermentioned chamber side control part 121 (Figure 10) in the mode that can carry out signal communication, the detected value of limit switch 110L, 110R exports chamber side control part 121 (Figure 10) to, and chamber side control part 121 exports this detected value to indoor pusher side control part 120.
As mentioned above, between 100 on-stream periods of ceiling embedded type air conditioner, because cleaning brush unit 51 is positioned at position of readiness H1, so limit switch 110L, 110R become on-state; During the dust of removing air cleaner 40, because cleaning brush unit 51 scans, so limit switch 110L, 110R become off-state.
Fig. 7 is the side view of cleaning brush unit 51.
As shown in Figure 7, cleaning brush unit 51 has dust receiving room (dust acceptance division) 67 below spin-cleaning brush 64, and this dust receiving room 67 receives by this spin-cleaning brush 64 and scrapes the dust of (removing) and temporarily accumulate this dust.As shown in Figure 1, this dust receiving room 67 is outstanding between guide rail 52L, 52R, and below the width that descends side body 62 is integrally formed in this time side body 62.
And lower cover 68 has the extension 68A that extends to hinge axis 69 sides, is formed with outstanding a plurality of leg-of-mutton protrusion tab 91 on this extension 68A downwards.These protrusion tabs 91 on the width of dust receiving room 67, be separated by the regulation the interval and be made as roughly the same size, when making cleaning brush unit 51 move on the disposal box 57, itself and this disposal box 57 butts, and have resistance elastic force and open the function of lower cover 68.
Fig. 8 is the sectional side view of expression cleaning brush unit 51 and disposal box 57, and Fig. 9 is the sectional side view of the state of the expression cleaning brush unit 51 above-mentioned dust shift position H2 that moves to disposal box 57 tops.In this Fig. 8, Fig. 9, omitted the record of speed change tooth etc.
As shown in Figure 8, open and form the case body 92 of case shape above disposal box 57 has and at this loam cake 93 to be opened/closed above case body 92.As shown in Figure 9, when cleaning brush unit 51 moved on the disposal box 57, this loam cake 93 was opened, and was received from the dust that the dust receiving room 67 of cleaning brush unit 51 is cast.
In addition, loam cake 93 is formed with outstanding upward a plurality of leg-of-mutton protrusion tab 96.These protrusion tabs 96 on the width of disposal box 57 across the regulation the interval and be set as roughly the same size, when making cleaning brush unit 51 move to disposal box 57, dust receiving room 67 butts of itself and cleaning brush unit 51 have resistance elastic force and open the function of loam cake 93.
In this structure, disposal box 57 releasably is supported on and sucks grid 30.Therefore, when on sucking grid 30 disposal box 57 being installed, disposal box 57 is along with lifting is carried out in the lifting of lifting unit 35.Therefore, in the present embodiment, lifting unit 35 is as the elevating mechanism of disposal box 57 liftings is worked.
If disposal box 57 is described in detail with respect to the mounting structure that sucks grid 30, then as shown in Figure 8, on suck grid 30, pair of support parts 32A, the 32B of supporting disposal box 57 is provided with across erectting with the roughly the same interval of the width of the case body 92 of this disposal box 57, is formed with recess 32A1,32B1 respectively on the medial surface of these supports 32A, 32B.The teat 97,98 of side 92A, 92B and these recesses 32A1, the 32B1 card that are formed at the case body 92 of disposal box 57 respectively end, thereby prevent that disposal box 57 from coming off easily from support 32A, 32B.
When disposal box 57 is installed on support 32A, 32B, by between this support 32A, 32B, being pressed into disposal box 57, thereby make this support 32A, 32B arrow Y direction bending in Fig. 8, in case above-mentioned protuberance 97,98 embeds recess 32A1,32B1, then because this support 32A, 32B return to original state, so disposal box 57 is limited to support 32A, 32B.
And, with disposal box 57 from support 32A, when 32B pulls down, for example, make a support 32A, thereby remove the engaging between protuberance 97 and the recess 32A1, and pull down disposal box 57 upward to the bending of above-mentioned arrow Y direction.Thus, disposal box 57 easily can be loaded and unloaded support 32A, the 32B that sucks grid 30.
At this, the operation when removing the dust of air cleaners 40 by the cleaning agency 50 and operation of dust when disposal box 57 moves described at dust shift position H2.
If make the mobile of cleaning agency 50 with motor 81 actions, then should move with the rotation of motor 81 and transmit via a plurality of speed change teeth directional pinions 88,90, by the rotation of this pinion 88,90, cleaning brush device 51 comes and goes on guide rail 52L, 52R and moves.
In addition, if make 71 actions of cleaning brush CD-ROM drive motor, then as shown in Figure 8, the rotation of this cleaning brush CD-ROM drive motor 71 is transmitted via a plurality of speed change teeth directional spin-cleaning brushes 64, and this spin-cleaning brush 64 is along arrow B direction rotation among the figure.Utilize the rotation of this spin-cleaning brush 64, be rotated cleaning brush 64 attached to the dust on the air cleaner 40 200 and scrape, and attached on this spin-cleaning brush 64.In housing 61, the dust peel plate 58 in the whole width extension of this spin-cleaning brush 64 is installed below spin-cleaning brush 64.This dust peel plate 58 makes its front end crooked and have and these spin-cleaning brush 64 claws that contact towards roughly brushing the direction of 64 outer peripheral faces along spin-cleaning, during 64 rotations of spin-cleaning brush, this spin-cleaning brush 64 contacts with above-mentioned claw, brushes on 64 adhered dust 200 and takes in to dust receiving room 67 thereby peel off spin-cleaning.
When dust receiving room 67 (cleaning brush unit 51) moved to dust shift position H2, the dust of taking in this dust receiving room 67 200 was cast this disposal box 57.Specifically, cleaning brush unit 51 on disposal box 57 when mobile, the protrusion tab 96 that on the loam cake 93 of disposal box 57, forms and dust receiving room 67 butts of cleaning brush unit 51.Because this protrusion tab 96 has towards cleaning brush unit 51 and the hypotenuse portion of extending downwards, so under the state of this hypotenuse portion and dust receiving room 67 butts, if this dust receiving room 67 is to disposal box 57 side shiftings, then be accompanied by this move operation, protrusion tab 96 is pressed, and loam cake 93 is opened for the inboard of middle mind-set case body 92 with hinge axis 94.
On the other hand, for the lower cover 68 of the dust receiving room 67 of cleaning brush unit 51, be formed at case body 92 butts of protrusion tab 91 and disposal box 57 of the extension 68A of this lower cover 68.Because this protrusion tab 91 has towards cleaning brush unit 57 and the hypotenuse portion of extending upward, so under the state of case body 92 butts of this hypotenuse portion and disposal box 57, if this dust receiving room 67 is to disposal box 57 side shiftings, then be accompanied by this shift action, protrusion tab 91 is pressed, and lower cover 68 is opened for the outside of middle mind-set dust receiving room 67 with hinge axis 94.Thus, the dust 200 in the dust receiving room 67 is cast in the case body 92 of this disposal box 57 via the top quilt of the loam cake 93 of disposal box 57.
If have dust, then suck grid 30 declines, thereby disposal box 57 is descended by making in disposal box 57 inner products.Because these disposal box 57 loading and unloading are disposed at freely and suck grid 30, pull down the dust that also can easily remove in the disposal box 57 so these disposal box 57 self-primings can be gone into grid 30.Fell when disposal box 57 both can reach the stipulated time in the duration of runs of ceiling embedded type air conditioner 100, in addition, the full quantity sensor that detects the dust amount in the disposal box 57 was set, and when this full quantity sensor has been worked, disposal box 57 was descended.
Figure 10 is the block diagram of the functional formation of expression ceiling embedded type air conditioner 100.
As shown in the drawing, ceiling embedded type air conditioner 100 has: be set at the indoor pusher side control part 120 that the electric mounting box on the drain pan 13 of body unit 1 is taken in; Be arranged at the chamber side control part 121 of filtering chamber 20; Be arranged at the grid side control part 122 of decorative panel 21.These control parts connect in the mode that can carry out signal communication.
Indoor pusher side control part 120 is control parts of the various piece of central control ceiling embedded type air conditioner 100, has: as CPU (the Central Processing Unit: CPU) of computing executing agency; The primary control program (PCP) that this CPU carries out; Store ROM (the Read Only Memory: read-only storage) of the data etc. of this primary control program (PCP) non-volatilely; RAM (the Random Access Memory: random access memory) of the data that the program that temporary transient storage CPU carries out or this program relate to etc.; And other peripheral circuits etc.And indoor pusher side control part 120 is carried out the timing of various timing actions and current time based on the reference clock pulse that not shown oscillator produces.
Indoor pusher side control part 120 has cleaning brush unit position detection part 120A (position detecting mechanism) and cleaning brush rotation test section 120B.
Cleaning brush unit position detection part 120A judges based on the output valve of limit switch 110L, 110R whether cleaning brush unit 51 is positioned at position of readiness H1.Specifically, when limit switch 110L, 110R export the signal of expression connection, be judged to be cleaning brush unit 51 and be positioned at position of readiness H1, when limit switch 110L, 110R at least any output expression disconnect signal the time, be judged to be cleaning brush unit 51 and be not positioned at position of readiness H1.Like this, because only be considered as cleaning brush unit 51 when limit switch 110L, 110R both sides connect is positioned at position of readiness H1 to cleaning brush unit position detection part 120A, even so when cleaning brush unit 51 causes cleaning brush unit 51 normally not to be positioned at position of readiness H1 with respect to sweep directions generation skew, also can detect above-mentioned situation.As mentioned above, the detected value of limit switch 110L, 110R exports chamber side control part 121 to, and chamber side control part 121 is exported it to indoor pusher side control part 120.
At this, as mentioned above, position of readiness H1 is set in different positions with dust shift position H2.Therefore, be positioned at position of readiness H1 during this being detected cleaning brush unit 51 by cleaning brush unit position detection part 120, cleaning brush unit 51 is not positioned at dust shift position H2 really.Cleaning brush unit position detection part 120 works as position detecting mechanism, and this position detecting mechanism is positioned at position of readiness H1 by detecting cleaning brush unit 51, thereby detects the dust shift position H2 that cleaning brush unit 51 is not positioned at disposal box 57 tops.Like this, cleaning brush unit position detection part 120 constitutes by detecting cleaning brush unit 51 and is positioned at position of readiness H1, thereby detect the dust shift position H2 that cleaning brush unit 51 is not positioned at disposal box 57 tops, can detect cleaning brush unit 51 thus effectively and not be positioned at disposal box 57 tops.
Cleaning brush rotation test section 120B judges based on the output valve of optical sensor 124 whether spin-cleaning brush 64 rotates.Specifically, after spin-cleaning brush 64 began rotation, cleaning brush rotation test section 120B calculated the rate of change of the light of spin-cleaning brush 64 reflections according to the detected value of optical sensor 124, based on result of calculation, judged whether spin-cleaning brush 64 rotates.As mentioned above, the detected value of optical sensor 124 exports chamber side control part 121 to, and exports to indoor pusher side control part 120 from chamber side control part 121.
Indoor pusher side control part 120 is connected with storage part 125.This storage part 125 is made of EEPROM, flash memory, and can rewrite the ground store various kinds of data under the control of indoor pusher side control part 120.Store in the storage part 125 and finish afterwards to show timetable 125A, the zero hour 125B, accumulated time table 125C.Narrate these timetables in the back.
Grid side control part 122 is arranged on the decorative panel 21, and sucks the controls such as lifting of grid 30 under the control of indoor pusher side control part 120, and it is connected with motor driving part 127, LED substrate 128, light accepting part 216B.In addition, with indoor pusher side control part 120 similarly, grid side control part 122 has CPU, ROM, RAM and peripheral circuit.
LED213B informs at suction grid 30 and has produced unusually.Specifically, when the lifting that sucks grid 30 is not normally carried out, perhaps, suck grid 30 when normally not being entrenched in the assigned position of suction inlet 22 of decorative panel 21, inform sucking grid 30 by flicker to have produced that certain is unusual.In addition, produced unusual inspection body, can use the mechanism that has utilized known technologies such as limit switch, optical sensor as detecting suction grid 30.
LED214B informs the current state that sucks grid 30.Specifically, when suction grid 30 was entrenched in the suction inlet 22 of decorative panel 21, LED214B extinguished; When sucking grid 30 declines, the LED214B flicker; When sucking grid 30 risings, LED214B lights.In addition, in the present embodiment,,, also can inform the state of disposal box 57 in the lump by informing the state that sucks grid 30 because disposal box 57 is inhaled into grid 30 supportings.
In user's remote controller 130 and indicated and suck grid 30 when falling, when be in the dust of removing air cleaners 40 by cleaning agency 50 during in the time, perhaps, be in described laterly when forbidding the lifting time zone at current time, LED215B glimmers.In the present embodiment, as described later, constitute when be in the dust of removing air cleaners 40 by cleaning agency 50 during in the time and in current time is in the scope of forbidding the lifting time zone time, by forbidding sucking the lifting of grid 30, thereby forbid the lifting of disposal box 57.The user is by the situation of identification LED214C flicker, this situation thereby the lifting that can grasp disposal box 57 is under an embargo.
As mentioned above, light accepting part 216B receives the signal that remote controller 130 sends, and exports this signal to grid side control part 122.Grid side control part 122 will export indoor pusher side control part 120 to by the signal of light accepting part 216B input.Indoor pusher side control part 120 is according to the various piece of being controlled ceiling embedded type air conditioner 100 by the signal of grid side control part 122 inputs.
Figure 11 (A) schematically shows the figure that finishes back timetable 125A, and Figure 11 (B) schematically shows the figure that shows 125B the zero hour, and Figure 11 (C) is the figure that schematically shows accumulated time table 125C.
In the present embodiment, condition as the dust that begins to remove air cleaner 40 by cleaning agency 50, can be chosen in behind the end of run of ceiling embedded type air conditioner 100 through this condition (being designated hereinafter simply as " condition A ") during predefined elapsed time T1 user's remote controller 130 elapsed time T1 among the A that just can impose a condition.If user's remote controller 130 is set elapsed time T1, then the signal of the expression elapsed time T1 that is sent by remote controller 130 exports indoor pusher side control part 120 to via light accepting part 216B and grid side control part 122.Indoor pusher side control part 120 is rewritten as the value of timetable 125A (Figure 11 (A)) after the end of storage in the storage part 125 value of the elapsed time T1 of expression user indication according to the signal by 122 inputs of grid side control part.Remove the condition of dust of air cleaner 40 to start with and during alternative condition A, indoor pusher side control part 120 is when the operation of ceiling embedded type air conditioner 100 stops, elapsed time is carried out timing, and with reference to finishing back timetable 125A, when the elapsed time reaches the elapsed time T1 that stores among the timetable 125A of end back, begin to remove the dust of air cleaner 40 by cleaning agency 50.
In addition, condition as the dust that begins to remove air cleaner 40 by cleaning agency 50, can select current time to reach this condition of predefined moment T2 (scanning the zero hour) (being designated hereinafter simply as " condition B "), user's remote controller 130 moment T2 among the B that just can impose a condition.In case user's remote controller 130 is set T2 constantly, then the expression of sending by remote controller 130 constantly the signal of T2 will export indoor pusher side control part 120 to by light accepting part 216B and grid side control part 122.Indoor pusher side control part 120 is according to the value that the value of showing 125B (Figure 11 (B)) zero hour of storage in the storage part 125 is rewritten as expression moment T2 by the signal of grid side control part 122 inputs.And, remove to start with air cleaner 40 dust condition and when having selected condition B, indoor pusher side control part 120 when current time reaches the moment of showing to store among the 125B zero hour, is begun to remove the dust of air cleaner 40 with reference to showing 125B the zero hour by cleaning agency 50.
And, condition as the dust that begins to remove air cleaner 40 by cleaning agency 50, this condition (being designated hereinafter simply as " condition C ") in the time of can selecting the Cumulative Elapsed Time of ceiling embedded type air conditioner 100 to reach predefined accumulated time T3, user's remote controller 130 accumulated time T3 among the C that just can impose a condition.In case user's remote controller 130 is set accumulated time T3, then the signal of the expression accumulated time T3 that sends of remote controller 130 will export indoor pusher side control part 120 to by light accepting part 216B and grid side control part 122.Indoor pusher side control part 120 is according to the value that the value of the accumulated time table 125C (Figure 11 (C)) of storage in the storage part 125 is rewritten as expression accumulated time T3 by the signal of grid side control part 122 inputs.And, remove to start with air cleaner 40 dust condition and when having selected condition C, the accumulated time of 120 pairs of ceiling embedded type air conditioners of indoor pusher side control part, 100 operations is carried out timing, and store storage part 125 into, and with reference to accumulated time table 125C, when current accumulated time reaches the time of storing among the accumulated time table 125C, begin to remove the dust of air cleaner 40 by cleaning agency 50.When having selected this condition C, in case because the Cumulative Elapsed Time of ceiling embedded type air conditioner 100 reaches the dust that accumulated time T3 will begin to remove air cleaner 40 automatically, thereby can improve user convenience.
In addition, the user both can remote controller 130 select above-mentioned condition A, B, C, also can not select any condition.
Get back to Figure 10 of front, chamber side control part 121 is arranged at filtering chamber 20, and under the control of indoor pusher side control part 120, can control cleaning agency 50 etc., and be connected with motor driving part 131, LED substrate 132, limit switch 110L, 110R, optical sensor 124.In addition, with indoor pusher side control part 120 similarly, chamber side control part 121 comprises CPU, ROM, RAM and peripheral circuit.
LED213C informs at cleaning agency 50 and has produced unusually.Specifically, when detecting spin-cleaning brush 64 by cleaning brush rotation test section 120B when normally not rotating, or the scanning when normally not carrying out of cleaning brush unit 51, produced by LED213C being glimmered inform cleaning agency 50 that certain is unusual.
LED214C informs whether the rotation brush unit 51 of cleaning agency 50 is positioned at position of readiness H1.Specifically, when rotation brush unit 51 was positioned at position of readiness H1, LED214C extinguished; When rotation brush unit 51 is not positioned at position of readiness H1, the LED214C flicker.According to this structure, by reference LED214C, the user can be easily and is promptly grasped rotation brush unit 51 and be not positioned at this situation of position of readiness H1.In addition, as mentioned above, the cleaning brush unit position detection part of indoor pusher side control part 120 detects rotation brush unit 51 and whether is positioned at position of readiness H1.
LED215C informs the dust that finishes to be removed by cleaning agency 50 air cleaner 40.Specifically, during the dust of end erase air cleaner 40, LED215C glimmers within a certain period of time.
Secondly, the action to ceiling embedded type air conditioner 100 describes.
At first, thus the action the when lifting that sucks grid 30 by indication indicated disposal box 57 liftings of these suctions grid 30 supportings, and the flow chart of use Figure 12 describes.In addition, in following action, indoor pusher side control part 120 works as lifting control mechanism.And, for convenience of explanation, will make this situation of disposal box 57 liftings abbreviate " disposal box 57 liftings " as along with the lifting that sucks grid 30.
If indication lifting disposal box 57 is then imported the signal (step SA1) of representing its purports to indoor pusher side control part 120.Then, the cleaning brush unit position detection part 120A of indoor pusher side control part 120 judges according to the output valve of limit switch 110L, 110R whether cleaning brush unit 51 is positioned at position of readiness H1 (step SA2).In addition, as mentioned above, when detecting cleaning brush unit 51 when being positioned at position of readiness H1, cleaning brush unit 51 is not positioned at the dust shift position H2 of disposal box 57 tops really.
When detecting cleaning brush unit 51 when being positioned at position of readiness H1 (step SA2: be), be cleaning brush unit 51 when not being positioned at dust shift position H2, indoor pusher side control part 120 judges that current time is whether in the scope of forbidding the lifting time zone that sucks grid 30 (step SA3).At this, describe in detail forbidding the lifting time zone.
Forbid that the lifting time zone is meant the time zone of forbidding sucking grid 30 and disposal box 57 liftings.In the present embodiment, when having selected above-mentioned condition B as the condition of the dust that begins to remove air cleaner 40 by cleaning agency 50, be set at as forbidding the lifting time zone and comprise the time zone of T2 constantly.In more detail, forbidding that the lifting time zone is configured to comprise from reaching constantly T2 begins to remove the time zone of the dust of air cleaner 40 to end erase.For example, if be 12:05 as the moment T2 of zero hour of the dust of removing air cleaner 40, be 12:10 the finish time, forbids that then the lifting time zone is set at 12:00～12:15.In addition, remove the condition of dust of air cleaner 40 to start with and during non-selected condition B, do not set and forbid the lifting time zone.
In step SA3, (step SA3: not) when judging that current time is being forbidden outside the scope in lifting time zone, indoor pusher side control part 120 control grid side control parts 122 allow disposal box 57 liftings also to carry out lifting (step SA4), and inform (step SA5).Specifically, when falling disposal box 57, indoor pusher side control part 120 control grid side control parts 122 also make the LED214B flicker; When disposal box 57 was risen, indoor pusher side control part 120 control grid side control parts 122 also lighted LED214B.On the other hand, when judging that current time is being forbidden within the scope in lifting time zone (step SA3: be), indoor pusher side control part 120 is forbidden sucking the lifting of grid 30 and disposal box 57 and is not carried out lifting (step SA6), and informs (step SA7).Specifically, indoor pusher side control part 120 is controlled grid side control parts 122 and is made the LED215B flicker.Then, indoor pusher side control part 120 returns the processing of step SA2, judges once more whether cleaning brush unit 51 is positioned at position of readiness H1.
Get back to step SA2, when cleaning brush unit 51 is not positioned at position of readiness H1 (step SA2: not), indoor pusher side control part 120 is forbidden sucking the lifting of grid 30 and disposal box 57 and is not carried out lifting (step SA6), and informs (step SA7).Specifically, indoor pusher side control part 120 is controlled grid side control parts 122 and is made the LED215B flicker.Then, indoor pusher side control part 120 returns the processing of step SA2, judges once more whether cleaning brush unit 51 is positioned at position of readiness H1.
Like this, in the present embodiment, when cleaning brush unit 51 was positioned at position of readiness H1, indoor pusher side control part 120 allowed the lifting of disposal box 57; When cleaning brush unit 51 was not positioned at position of readiness H1, indoor pusher side control part 120 was forbidden the lifting of disposal box 57.At this, when cleaning brush unit 51 is positioned at the dust shift position H2 of disposal box 57 tops, make under the situation that sucks grid 30 liftings, might cause the accident contact between cleaning brush unit 51 and the disposal box 57.But, in the present embodiment, be positioned at position of readiness H1 when detecting cleaning brush unit 51, when promptly not being positioned at dust shift position H2 really,, can prevent the accident contact between cleaning brush unit 51 and the disposal box 57 owing to allow the lifting of disposal box 57.
And, in the present embodiment, when having selected condition B to remove the condition of dust of air cleaner 40 to start with, comprise as the moment T2 of zero hour of the dust of removing air cleaner 40 forbid forbid the lifting of disposal box 57 in the lifting time zone.
