bar usefulness track

18,19 with guiding groove 18b, 19b of rail groove 18a, the 19a of tooth bar 20 usefulness by last item.

Like this, the tooth bar that the axle by last item 24 its right sides of the cam 21 on right side enters the right side with track 19 by last item with guiding groove 19b and be directed, in addition, the axle by its left side of last item 24 of the cam 21 in the left side tooth bar that enters the left side with track 18 by last item with guiding groove 18b and be directed.

In addition, make this by last item guiding groove 18b, the front side wall 18c of 19b, the front side wall on the top of 19c partly becomes along with the convergence top, open rake 18d and form to the front face side transition, 19d, rising to this opening rake 18d by last item 24, during 19d, press last item 24 at

open rake

18d, 19d reaches front face side, simultaneously, it is forwards open to press last item 24, cam 21 forwards rotates, the bottom of shutter 9 forwards is pushed out, by the top end difference 9d of shutter 9, the top becomes the anterior locations same with front panel 7, can block blow-off outlets 6 by shutter 9.

Illustrate in greater detail the action of shutter 9 bottoms.Figure 13 is that the tooth bar in explanation left side is analysed and observe key diagram with the side-looking of the major part of the action of the cam 21 on the top of track 18 and shutter 9.The line of cam 21 usefulness single-points is represented.In addition, tooth bar 20 is only represented the sliding pin 20b on top with the single-point line.The action of position when the position of B rises of shutter 9 A from figure is described then.

In the drawings about the position of A, shutter 9 is positioned at the rear of comparing with front panel 7 at shutter 9, and shutter 9 rises on the rear of plate in front.At this moment, the tooth bar side installation shaft 22 of deadweight of having born shutter 9 forms installation portion 20c being positioned at the mode at the rear of comparing with blinds reveal installation shaft 23, and therefore, because the deadweight of shutter 9, forwards Xuan Zhuan power always is applied on the cam 21.But, because be pressed axle with the front side wall 18c pushing of guiding groove 18b, so even shutter 9 rises, shutter 9 can forwards not move yet by last item 24.

Then, if because the rising of tooth bar 20, shutter 9 further rises to the position of B among the figure, then arrive at by the open rake 18d of last item with guiding groove 18b by last item 24, forwards move along open rake 18d, because the deadweight of shutter 9, cam 21 forwards rotates, release the bottom of shutter 9, therefore, shutter 9 forwards stretches out, by the top end difference 9d of shutter 9, be the anterior locations identical up, can block blow-off outlet 6 with front panel 7.In addition, in the explanation of Figure 13, the tooth bar in left side is illustrated with track 18, the tooth bar on relative right side by cam 21, similarly forwards stretches out shutter 9 with track 19 also action simultaneously.

In addition, in the bottom of shutter 9 when so forwards mobile, top at shutter 9, the pin 9a on top is also as above-mentioned, forwards move from rake 11b, the 12b of rail groove 11a, the 12a of used in

blinds track

11,12, the part of the covering blow-off outlet 6 of shutter 9 and front panel 7 front and back are with one side.

In addition, in this embodiment, when end difference 9b is formed at the bottom at shutter 9, during shutter 9 total blockage blow-off outlets 6, end difference 9b overlaps the back of plate 7 in front, therefore, because the end difference 9b of front panel 7 and shutter 9 can not see the inside of air conditioner main body 1 from the gap of upper section.

In addition, end difference 9b also is two ladders, top end difference 9d forms deeplyer than below end difference 9c, and therefore, the angle one side when the end difference 9b top of the top of front panel 7 and shutter 9 is moving forward and backward, during the one side lifting, be difficult to interfere with front panel 7, can easily make the shape on front panel 7 tops, simultaneously, by dark top end difference 9d, can improve the intensity of the left and right sides width of shutter 9.

In addition, in above-mentioned, shutter 9 is risen, the situation of closing blow-off outlet 6 is illustrated, and under the situation of opening shutter 9, can certainly shutter 9 rearward be moved by the opposite action of each part, is housed in the rear of front panel 7.

In addition, in this embodiment, what represent is, because formed to prevent when rising to the position of regulation by last item 24, cam 21 forwards rotates, simultaneously, and at

open rake

18d, 19d, the front side wall 18 that the mode that can forwards rotate is open, 19c, so, at tooth bar track 18, form on 19 by last item guiding groove 18b, 19b has reduced number of spare parts, make easily, cheap article, but, also can with tooth bar with

track

18,19 splits ground forms pushes axle guiding groove 18b, 19b also can only form front side wall 18c, the part of 19c, even not necessarily groove shape also can form.

Then, to shutter 9 can by tooth bar 20 and cam 21 can the side-to-side vibrations smooth and easy lifting in ground suitable dimensions describe.As can be seen from Figure 5, form highlightedly at the left and right sides both sides of the chest on tooth bar 20 tops, as respectively and about the linking part that links of cam 21 about installation portion 20c between size E, be narrow width with respect to the scope of the 1/4-2/4 of the width G size of shutter shown in Figure 11 9.In addition, form highlightedly as inboard one at the shutter 9 that constitutes by plastic components, as respectively and about cam 21 another binding linking part about installation portion 9e between size F too, be the narrow width with respect to the scope of the 1/4-2/4 of the width G size of shutter 9, lifting shutter 9 very swimmingly.

In addition, size E and size F get final product about half of G size.If the size F between the installation portion 9e of size E between installation portion 20c and shutter 9 is 2/4 wideer than the width dimensions G size of shutter 9, then exist the left and right sides width of tooth bar 20 wide, tooth bar 20 increases, weightening finish, tilt easily, simultaneously, in order to make 20 liftings of big, heavy tooth bar, the big motor that needs strong moment of torsion, the technical problem of energy that need be useless etc.

Therefore, the size of space F of installation portion 9e that makes the installation portion 20c size of space E of tooth bar 20 and shutter 9 gets final product in the narrow scope (scope of about 25%-about 50%) of the 1/4-2/4 of the left and right sides of shutter 9 width G size shown in following formula.

(G*1/4)≤E≤(G*2/4)

(G*1/4)≤F≤(G*2/4)

By becoming such size, prevented inclination as the installation portion 20c about the linking part on tooth bar 20 tops, can by about cam 21, mention shutter 9 swimmingly, can carry out the lifting of shutter 9 swimmingly.

In addition, size E and size F are in same position, the left and right sides with respect to cam 21.

Like this, because make the size of space F of installation portion 9e of the size of space E of installation portion 20c of tooth bar 20 and shutter 9 identical, be in identical position, the left and right sides, so, the power of tooth bar 20 liftings easily by about cam 21 transmit to shutter 9, can make shutter 9 liftings swimmingly.

In addition, the size of space F of the size of space E of installation portion 20c and installation portion 9e makes the warpage of cam 21, even there are some different sizes also passable.

In addition,, make the width G of shutter 9 be of a size of 500mm, make size E between tooth bar 20 installation portion 20c and the size G between shutter 9 installation portion 9e be respectively 190mm, just can make shutter 9 liftings swimmingly by the lifting of tooth bar 20 as an example.

In addition, in the above-described embodiment, expression be to make about being shaped as of cam 21 roughly symmetry, about cam 21 use same cam, because of assembly defect, produce the cheap article of expense that cause in batches, but, press in the last item 24, the cam 21 on right side can not have the left side by last item 24, in addition, the cam 21 in left side can not have yet the right side by last item 24, can be about respectively different cam faces.

Then, by the flow chart of Figure 14, the summary with the automatic shutter action of the shutter 9 of the running of vertical air conditioner 100 action interlock is described.

(1) in step 101, pushes the running switch of the controller portion 8 of vertical air conditioner 100.

(2) in step 102, motor 17 starting operations, tooth bar 20 descends, and shutter 9 descends, and opens blow-off outlet 6.

(3) in step 103,, detect the situation that shutter 9 is opened fully by the not shown detecting sensor that goes out etc.

(4) in step 104, if detecting shutter 9 opens fully, then motor 17 stops.

(5) in step 105, the running of putting in blast fan 5, carry out based on the not shown cold-producing medium circulation that goes out etc. refrigeration, heat.

(6) then, under the situation of the running that finishes air conditioner, in step 106, slave controller portion 8 closes the running switch of air conditioner.

(7) in step 107, the running of out-of-blast fan 5, stop based on cold-producing medium circulation etc. refrigeration, heat.

(8) in step 108, make motor 17 counter-rotatings, tooth bar 20 is risen, mention shutter 9, close blow-off outlet 6.

(9) in step 109,, detect the situation that shutter 9 is closed fully by the not shown detecting sensor that goes out etc.

(10) if by detecting sensor etc., detect shutter 9 to close fully, then in step 110, stop motor 17, stop the running of vertical air conditioner 100, until next running instruction is arranged.
