Description

The air outlet that hot and cold wind is dual-purpose

The dual-purpose air outlet of a kind of hot and cold wind belongs to air-conditioning blowing device manufacturing technology field.

The dual-purpose air outlet of the hot and cold wind of central air conditioning air-supply usefulness generally is made of TEMP executive component, top air-supply housing, bottom air diffuser and other auxiliary, as shown in Figure 1.Wherein, the 1st, top air-supply housing, the 2nd, support, the 3rd, white oil formula temperature one displacement transducer, the 4th, but roll adjustment bolt, the 5th, tiltedly, blow the formula air diffuser, be the circular parachute blade that links to each other with switch lever 6 in the middle of it, both sides are inclined blowing type blades, the 7th, spring.When sending into cold wind, air-flow is oblique blowing out from both sides; When sending into hot blast, the sensor 3 drives switch lever 6 through spring 7 the circular parachute blade is pressed down, and air-flow is tiltedly blown downwards from the centre.Its shortcoming is: less because of the coefficient of volume expansion of white oil, and make switch lever 6 operating distances too small, can only blow out about about one meter distance to the hot blast that declivity is blown, do not reach the requirement of hot-air heating.

It is a kind of to wind pushing temperature is highly sensitive, that operating temperature is wide, the hot blast through type blows out and air supplying distance the is far away dual-purpose air outlet of hot and cold wind that the purpose of this utility model is to provide.

Of the present utility model being characterised in that: it is with a high sensitivity, temperature one displacement transducer 8 of wide warm area, with its head, support 2 and switch lever 6 that the tail two ends connect respectively, the movable drawing plate 9 affixed with this switch lever 6, the housing 10 that an one side links to each other with support 2, the spring 7 that two ends link to each other with support 2 with switch lever 6 respectively, the central shaft at its blade two ends passes and is fixed on slidably behind the cross-drilled hole on the movable drawing plate 9 on the housing 10 and the opposite opened blind window 11 that the end axle of one end can slide and combine in pairs in the vertical core on the movable drawing plate 9 again, its air inlet top air-supply housing 1 that both sides link to each other with the aluminium frame 13 that is welded in housing 10 sides admittedly with being connected the solid weldering of airduct short tube 12 with and blade and top oblique that housing 1 lower air outlet links to each other of blowing, directly blow dual-purpose type air diffuser 14 and form, its assembly structure figure is seen Fig. 2.

Use proof: it has satisfied designing requirement well.

In order in conjunction with the embodiments the utility model to be done detailed describing below, show as follows employed accompanying drawing number of present specification and title brief introduction:

Fig. 5: the front view of opposite opened shutter;

Fig. 6: the structure principle chart of splitting the louver valve;

Fig. 7: hot and cold wind air supplying distance schematic diagram (air-supply one's intention as revealed in what one says wind speed 3 meter per seconds, the air-supply and 8 ℃ of the room temperature temperature difference).

Ask for an interview Fig. 1～Fig. 6.Wherein, temperature one displacement transducer 8 of high sensitivity, wide warm area is by bellows 15, on one side the diaphragm seal 16 that welds admittedly of stomidium, one end pass the thin copper tube 18 that the other end seals again with its solid weldering in one side stomidium that the thick copper tube 17 and an other one end of diaphragm seal 16 backs and its solid weldering stretch into thick copper tube 17 from the outside of bellows 15 and constitute behind the working media FC72 that packs into commercially available (Developmental Material, this medium be contaminated air, non-corrosiveness, nontoxic not) with it.Be heated back evaporation of medium FC72 just can utilize the reaction force principle to make thin copper tube 18 produce big displacement, and the operating temperature of medium is that 0～60 ℃, corresponding displacement are between 0～65 millimeter.Wherein, tiltedly, directly blow dual-purpose type air diffuser 14 by the tilting that is positioned at both sides and be positioned at the middle part rectilinear blade constitute.Its outermost two sides with top air-supply housing 1 are connected with screw, and all the other all weld admittedly with it.In Fig. 1, aluminium frame 13 with connect with screw with air-supply housing 1 both sides, top that are connected airduct short tube 12 welding; Thin copper tube 18 in temperature one displacement transducer 8 of high sensitivity, wide warm area is connected with switch lever 6 screws by weldering tagger 19 thereon; Bellows 15 is fixed in the circular hole of support 2; Spring 7 one ends are fixed by bolts on the switch lever 6, but the other end is fixed on the support 2 with roll adjustment bolt 4.Fig. 6 is a structure principle chart of splitting the louver valve of forming by housing 10, movable drawing plate 9, with its switch lever that welds mutually 6 and opposite opened blind window 11.Wherein, also can rotate therein in 20 dead eyes in housing 10 of the central shaft of opposite opened blind window 11 both sides, its end axle 21 can rotate around central shaft along with moving of this plate in the vertical core of movable drawing plate 9, and its displacement is controlled by switch lever 6 by temperature one displacement transducer 8.

In Fig. 1, RF represents hot blast, and LF represents cold wind, the aperture of opposite opened blind window 11 when chain-dotted line represents that direct-passing mode send hot blast, its aperture when solid line is represented to send cold wind.Fig. 7 is exactly the air supplying distance figure under above-mentioned two kinds of different situations.The dual-purpose air outlet of the hot and cold wind that the utility model proposes can directly be delivered to ground to hot blast, shown in a following dotted line; If when adopting the cold wind side-blown then do not accomplish this point, shown in a top dotted line.

Its characteristic of temperature one displacement transducer of the employed high sensitivity of the utility model, wide warm area is as follows: the sequence number temperature (℃) length (millimeter) elongation (millimeter) pipe internal pressure (Kgf/cm ²)1 0.8 65 0 ～0.0012 10.2 69 4 0.023 17.1 73 8 0.14 21.5 78 12 0.125 26.3 83 18 0.156 32.8 95 30 0.207 38.0 100 35 0.308 46.2 110 45 0.499 47.4 112 47 0.5210 52.4 118 53 0.6211 59.9 130 65 0.80

Simultaneously, because that operation material FC72 has is nontoxic, do not fire, advantages such as no atmosphere pollution and non-corrosiveness, thereby very safe during use.
