The energising of the pressure fan of ceiling air conditioner, the air of the indoor that sucks by suction inlet are discharged by outlet after carrying out heat exchange through the refrigerant of indoor heat converter, reach the purpose of cleaning room air.
Described front panel comprises the suction grid 7 that comprises filter of floating dust in the filtered air etc., is installed in the filter that sucks grid to clean by certain cycle, prevents the pollution again of room air.But the suction grid that is installed on the filter 9 is arranged on the front panel 2, and front panel height overhead is about 2.4m, and the user must use ladder etc. just can take the suction grid apart, and this is very inconvenient.
Summary of the invention
Technical problem to be solved by this invention is that a kind of indoor set of the ceiling air conditioner of cleaning and filtering the most easily is provided.
For the technical solution problem, the technical solution used in the present invention is: a kind of indoor set of ceiling air conditioner, indoor set comprises and is formed with suction inlet, the suction grid of filter is housed on the suction inlet, be formed with outlet, the front panel that install to suck grid makes and sucks the assembly that moves up and down that grid moves up and down, move up and down assembly and comprise the electric wire that the suction grid is moved up and down, provide the motor of driving force and the cam of change electric wire moving direction to electric wire, the heavy burden that cam is fixed on according to cam moves up and down on the fixator of certain distance, fixator comprises the retainer body of stationary cam and the fixedly guidance part that moves up and down according to the heavy burden of cam guiding retainer body, installs according to loading on heavy burden on the cam at the downside of retainer body and confirms the 1st switch and the 2nd switch of the mobile status of electric wire.
When the 1st switch made the suction grid rise to the installation site of front panel by electric wire, contact was formed on the discharge portion that sucks above the grid, and activation signal is communicated to control part; The retainer body that the 2nd switch contact moves up and down also is communicated to control part to signal.
The invention has the beneficial effects as follows: ceiling air conditioner of the present invention possesses to make and sucks the assembly that moves up and down that grid moves up and down, and can clean or change the filter that is contained on the indoor set easily, prevents that the user is because of the generation security incident of climbing.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
Shown in Fig. 4～8, ceiling air conditioner of the present invention is installed between indoor the furred ceiling wall A and furred ceiling face, indoor set comprises and exposing at indoor casing 10, be installed in the indoor heat converter 12 that can make air and refrigerant heat exchange in the casing, the pressure fan 14 of circulation casing inner air, the control part (not shown) of the drainage arrangement 16 of the condensate water that the discharge indoor heat converter produces and control indoor set.
Can move up and down the assembly 40 that moves up and down that sucks grid and be installed in the indoor set, move up and down assembly 40 and can move up and down and suck grid 30, make to separate to suck grids 30 to carry out cleaning and filtering 32 more convenient from front panel 20.
Move up and down assembly 40 and comprise the moving-member of removable suction grid 30, the driver part of mobile moving-member, change the change moving-member that moves by driver part moving direction cam 46 and be fixed in cam and move up and down the fixator 48 of certain distance according to the heavy burden of cam.Fixator 48 is to confirm to suck the affirmation parts that grid 30 moves, and comprises the 1st, 2 switch 60,62.
Driver part is a motor 44, moving-member is the electric wire 42 that connects motor 44 and suck grid 30, cam 46 is positioned at the centre that connects motor 44 and suck the electric wire 42 of grid 30, the moving direction of guiding electric wire 42, though fixator 48 is installed on the casing 10, move a certain distance according to the heavy burden of cam.
Simultaneously, the downside of retainer body 49 has been installed the 1st, 2 switch 60,62, the 1 switches 60 and has been made by electric wire 42 and suck grid 30 when rising to the installation site of front panel, and contact is formed on discharge portion 20 activation signals that suck above the grid 30 and is communicated to control part.
When sucking grid 30 when descending, if the suction grid 30 that descends contact with barrier or electric wire 42 generation problems can not untie the time, the above-mentioned situation of the 2nd switch 62 affirmations.If above-mentioned situation takes place, cam 46 takes place because of sucking the counter motion that heavy burden caused of grid 30, and move up and down certain distance by counter motion retainer body 49, and the retainer body 49 that the contact of the 2nd switch 62 moves up and down and signal is communicated to control part.
Below enforcement control procedure of the present invention is elaborated by Fig. 4:
At first, indoor set and off-premises station operation are piled up pollutants such as dust through the filter of certain hour front panel 42, must cleaning.At this moment the user handles control part, and in order to clean, the suction grid 30 on the front panel 32 must drop to indoor.
By control part drive motors 44, unclamp the electric wire 42 that is centered around motor 44 suction grid 30 is descended.
Suck grid 30 and drop to certain altitude, the user handles control part makes suction grid 30 stop to descend, and takes the filter 32 that filter cleans or more renews apart.
But, suck grid 30 in the way that descends, suck grid 30 and barrier, during as collisions such as people's hair or other chairs, as the suction grid 30 that continues to descend, sucking grid 30 and barrier may sustain damage, and starts the 2nd switch 62 when sucking the collision of grid 30 and barrier.
The 2nd switch 62 is when sucking the collision of grid 30 and barrier, the heavy burden that loads on above-mentioned cam 46 disappears for the moment, if and the heavy burden that loads on cam 46 disappears for the moment, then because of the retainer body 49 of counter motion stationary cam 46 along with fixator guidance part 50 rising certain distances.Simultaneously, sucking grid 30 handles normal, drop to user's height convenient for cleaning, after the cleaning of filter 32 or the replacement, the user handles control part makes fixator guidance part 30 go back up to original position, during fixator guidance part 30 rise original positions, the 1st switch 60 contact discharge portions 31 make control part cut off the power supply of motor 44.
