Under the state that blow-off outlet 15 opens wide by wind direction adjustment blade 31, the blow out air blown out from blow-off outlet 15 roughly flows along the inner panel 31b of wind direction adjustment blade 31.That is, roughly along the blow out air that the tangential direction of the end of scroll portion 17 is blown, its wind direction by wind direction adjustment blade 31 slightly on be changed.
(3) the concrete structure of wind direction adjustment blade 31
Fig. 3 is the stereogram of wind direction adjustment blade 31.Fig. 4 is the exploded perspective view of wind direction adjustment blade 31.In Fig. 1 ~ Fig. 4, wind direction adjustment blade 31 is to form the hollow structure of the mode overlap of hollow bulb 31c by outside plate 31a and inner panel 31b.
Further, two bights being positioned at the both ends on same long limit in four bights that wind direction adjustment blade 31 is rectangle when top view are cut into rectangular-shaped shape.For convenience of explanation, the region with the longest limit is called the 1st region R1, the region on the limit with the second length is called the 2nd region R2.Turning cylinder 311 is located at the two ends of the long side direction of the 2nd region R2.
(3-1) outside plate 31a
The periphery of outside plate 31a swells and forms wall 31aa, and the height of wall 31aa is set to be greater than the size of the thickness of inner panel 31b.The axial wall 31ab at the two ends of especially suitable with the 2nd region R2 part is formed as higher than another wall 31aa, and turning cylinder 311 is given prominence to toward the outer side from wall 31ab.
Fig. 5 is the amplification stereogram of axial wall 31ab periphery.In Figure 5, the rib 31ac adjacent with wall 31aa and axial wall 31ab is formed with at the medial surface of outside plate 31a.The height that even if the height of rib 31ac is configured to inner panel 31b when being placed on rib 31ac, inner panel 31b also can not spill into the position more top than the upper end of wall 31aa.
Outside plate 31a has the passage 312 of through axial wall 31ab and turning cylinder 311.With the medial surface of outside plate 31a for benchmark time, the height and position of passage 312 is lower than the centre-height of turning cylinder 311.More particularly, the height and position of passage 312 is set at such position: when inner panel 31b is placed on rib 31ac, the position opposed with the hollow bulb 31c formed between inner panel 31b and outside plate 31a (with reference to Fig. 1).
(3-2) inner panel 31b
The periphery 31ba of inner panel 31b embeds the wall 31aa of outside plate 31a and the inner side of axial wall 31ab.Inner panel 31b is entering predetermined distance to the inside position from periphery 31ba is formed with the opposed walls 31bb parallel with periphery 31ba.
The amplification stereogram of axial wall 31ab periphery when Fig. 6 is outside plate 31a and inner panel 31b overlap.In figure 6, the opposed walls 31bb of inner panel 31b is opposed with the wall 31aa of outside plate 31a and axial wall 31ab, forms the groove 313 surrounding opposed walls 31bb thus.
(3-3) hollow bulb 31c
As shown in the wind direction adjustment blade 31 of Fig. 1, hollow bulb 31c is formed between inner panel 31b when the overlapping and inner panel 31b of outside plate 31a and inner panel 31b is placed in rib 31ac and outside plate 31a.
Blow out air from blow-off outlet 15 flows on inner panel 31b, when thus supposing not arrange hollow bulb 31c, when blow out air is cold wind, wind direction adjustment blade 31 is cooled from inner panel 31b side towards outside plate 31a, the temperature of the outside plate 31a that cold wind does not touch also declines, and condenses when dropping to below dew-point temperature.
But by arranging hollow bulb 31c, the heat from inner panel 31b side moving and being cut off (heat insulation), outside plate 31a thus can be suppressed to be cooled, consequently to prevent condensation.
(3-4) parts 31d is used in sealing
Fig. 7 is the amplification stereogram of axial wall 31ab periphery when being filled with sealing parts 31d in groove 313.In the figure 7, groove 313 is boundaries of outside plate 31a and inner panel 31b, and by sealing with sealing parts 31d, hollow bulb 31c becomes airtight construction.Sealing parts 31d is the material identical with outside plate 31a and inner panel 31b, is filled in groove 313 with the state of melting.
The sealing parts 31d be filled in groove 313 is cooled and solidifies, and completes the sealing of the boundary of outside plate 31a and inner panel 31b thus.Now, wind direction adjustment blade 31 be formed as only allowing by passage 312 carry out inside and outside between the hollow airtight construction of air movement.
(4) direction controlling of blow out air
The indoor apparatus of air conditioner of present embodiment, as the means in the direction of control blow out air, makes wind direction adjust blade 31 and rotates the direction adjusting blow out air.
(4-1) usually pattern is blown out
Usual blowout pattern makes wind direction adjust blade 31 to rotate the pattern adjusting the direction of blow out air, comprises " usual fore blow " and " usual front blowing down ".
(4-1-1) usual fore blow
The side view of the wind direction adjustment blade 31 that Fig. 8 is blow out air when being usual fore blow.In fig. 8, when user have selected " usual fore blow ", the inner panel 31b that control part 40 makes the 1st wind direction adjustment blade 31 turn to wind direction adjustment blade 31 is in the position of approximate horizontal state.In addition, when the inner panel 31b of the adjustment of wind direction as the application's embodiment blade 31 is circular arc camber, makes wind direction adjust blade 31 and rotate till the tangent line of the front ends of inner panel 31b is in approximate horizontal state.Consequently, blow out air becomes fore blow state.
(4-1-2) usual front blowing down
The side view of the wind direction adjustment blade 31 that Fig. 9 is blow out air when being usual front blowing down.In fig .9, user, when making blow-off direction ratio " usual fore blow " downward, can select " usual front blowing down ".
Now, control part 40 makes wind direction adjust blade 31 rotation until the tangent line that wind direction adjusts the front ends of the inner panel 31b of blade 31 is in low early and high after state compared with horizontal line.Consequently, blow out air becomes blowing down state.
(5) move about the air by passage 312
No matter in which kind of situation of " usual fore blow " and " usual front blowing down ", wind direction adjustment blade 31 is all when heating by Hot-blast Heating, when freezing by cold front heavy rain.Therefore, the air in hollow bulb 31c is also heated or is cooled, and thus produces expansion or the contraction of air.
Suppose it is complete airtight construction, along with the expansion/contraction of hollow bulb 31c, wind direction adjustment blade 31 also expansion/contraction.But, this wind direction adjustment blade 31 be only allow by passage 312 carry out inside and outside between the hollow structure of air movement, thus can prevent wind direction from adjusting the expansion/contraction of blade 31.
In addition, turning cylinder 311 is formed through the sidewall portion the inside entering main body cover 11 that blow out stream 18, and thus the passage 312 self of through turning cylinder 311 is not present in the passage of blow out air.Therefore, even due to the expansion/contraction of air in wind direction adjustment blade 31, when air is moved in passage 312, also can prevent blow out air from being entered in wind direction adjustment blade 31 by passage 312.
Therefore, it is possible to avoid such situation: the cold air be blown when cooling operation by passage enter wind direction adjustment blade 31 in, from inner side by cooling air to adjustment blade 31.
Further, even when such as making the humidification running containing moisture in blow out air, also can prevent the air containing moisture from being entered in wind direction adjustment blade 31 by passage 312.Consequently, such as smaller in the possibility of the situation generation of the internal condensation of wind direction adjustment blade 31.
(6) the sealing manufacture method of parts 31d
The sectional area of groove 313 is 5 square millimeters or is less than 5 square millimeters, thus fills the sealing parts 31d not a duck soup of melting.In the present embodiment, the fill method of molten resin adopts WIM (Welding In Mold: welding in the mould) method of forming.
Figure 10 be patrix 71 and counterdie 81 by up and down separately time the sectional view of WIM mould 70.Further, Figure 11 is the sectional view of patrix 71 and the counterdie 81 WIM mould 70 when closing.In Figure 10 and Figure 11, such as, the sub-assembly of outside plate 31a and inner panel 31b overlap that makes as shown in Figure 6 is called patrix, upper die and lower die are closed.
In addition, Figure 10 and Figure 11 is that the parts be thus arranged in mould only illustrate the parts P with simple groove G for diagram by the accompanying drawing of multi-point sprue to the example of injection mo(u)lding molten resin in washing trough.
Be provided with multi-point sprue 77 at patrix 71, the molten resin injected by nozzle 73 from injection moulding machine is flowed into groove G by multi-point sprue 77.Therefore, the molten resin from each cast gate roughly moves equidistance, completes the filling to groove G, does not thus need injection pressure and molten resin temperature to set extra-high, and molten resin can be made to spread all over without interruption in whole groove G.
In addition, in the running channel 75 molten resin being directed to multi-point sprue 77, remain the amount of more than about 50 times of the amount of resin be filled in groove G, thus adopt the mould of hot runner mode, to reduce the discarded amount of resin.Hot runner mode uses heater 78,79 by surrounding's heating of running channel 75, molten resin maintained all the time the mode of molten condition.That is, the resin in running channel 75 does not solidify, and thus can use these resins and can not discard, both economical.
In addition, each cast gate of multi-point sprue 77 is conditioned temperature, thus suitably can maintain the molten resin temperature in running channel 75, also suitably can maintain the mobility of the molten resin of flowing in running channel 75.
In addition, carrying out pressure discharge for being detained the molten resin reaching the stipulated time more than, to prevent molten resin to be detained the stipulated time more than due to fault etc. in running channel 75, making the situation of the original physical property deterioration of this resin.In addition, when the sealing of manufacture embodiment is with parts 31d, the preferred stipulated time is 30 ~ 60 minutes.
Figure 12 be sealing parts 31d just shaping after running channel 75 and the stereogram of wind direction adjustment blade 31.In addition, the shape of running channel 75 is examples, is not limited to the shape of Figure 12.In fig. 12, the annulus that blacking represents is sealing parts 31d, and each cast gate of multi-point sprue 77 is opposed with sealing parts 31d.Like this, when sealing parts 31d is the less and long ring-type of sectional area, multi-point sprue 77 also can be adopted to carry out shaping.
(7) feature
(7-1) in indoor apparatus of air conditioner 10, air can only be to and from the inside and outside of wind direction adjustment blade 31 by passage 312.Further, because passage 312 is not in the passage of blow out air, the cold air be blown when cooling operation is thus avoided to be entered in wind direction adjustment blade 31 by passage.
(7-2) and, passage 312, not in the passage of blow out air, thus avoids the cold air that is blown when cooling operation to be entered in wind direction adjustment blade 31 by passage 312.
(7-3) and, blowout stream 18 and passage 312 are completely cut off by sidewall portion, thus avoid the cold air that is blown when cooling operation to be entered in wind direction adjustment blade 31 by passage 312.
(7-4) and, by wind direction being adjusted the overlapping and technique that is landfill sealing parts 31d in both boundary and groove 313 of the outside plate 31a of blade 31 and inner panel 31b, can suppress wind direction adjust blade 31 end face inside wall thickening, prevent the reduction of the volume of hollow space.
(7-5) and, by the material of outside plate 31a, inner panel 31b and sealing parts 31d is set to same material, compared with carrying out situation about engaging with the resin material different with linear expansion coefficient, the durability for thermal expansion/thermal contraction improves, and thus reliability improves.
