Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
See figures.1.and.2, Fig. 1 is the structural representation of a preferred embodiment of the utility model air conditioner temperature-sensitive head stationary installation, and Fig. 2 is the front view of air conditioner temperature-sensitive head stationary installation shown in Figure 1.The utility model air conditioner temperature-sensitive head stationary installation comprises clip 1, contiguous block 2 and bend pipe folder 3.Bend pipe folder 3 be the cell body of arc, the top that bend pipe the presss from both sides 3 outer side surfaces above-mentioned contiguous block 2 of formation that turns up, and define first opening 31.Contiguous block 2 extends upward from the top of bend pipe folder 3, and its end bends to arc and connects clip 1.Clip 1 is a hollow cylinder, and its bottom has along second opening, 11, the first openings 31 and second opening 11 of clip 1 longitudinal extension and is oppositely arranged.The bottom of clip 1 links to each other with the top of contiguous block 2.Clip 1 has temperature-sensitive head host cavity 12, and bend pipe folder 3 has elbow host cavity 32.In addition, second opening, 11 places of clip 1 are provided with outside flange 13, and bend pipe folder 3 notch both sides outwardly are provided with outside flange 33.
Further, above-mentioned bend pipe folder 3 is semi-round ring shape, has the xsect of circular arc.The xsect of clip 1 also is a circular arc.
With reference to Fig. 3, Fig. 3 is the assembling synoptic diagram of air conditioner temperature-sensitive head stationary installation shown in Figure 1.During assembling; Cylindrical temperature-sensitive head 4 is pressed along flange 13 by second opening 11 of clip 1 inward; Flange 13 receives outside expansionary force and outwards opens, and temperature-sensitive head 4 is pressed in the temperature-sensitive head host cavity 12, when temperature-sensitive head 4 is seated; Flange 13 is owing to the original position of recovery of elasticity, and the bottom of temperature-sensitive head 4 is from second opening, 11 protruding clips 1 at this moment.Flange 13 is set makes temperature-sensitive head 4 be convenient to assembling and dismounting, and avoid the edge incised wound temperature-sensitive head 4 of second opening 11.In the present embodiment; The width of second opening 11 is less than 1/2 of clip 1 cross-sectional circumferential; So temperature-sensitive head 4 can not come off from second opening 11, and clip 1 and temperature-sensitive head 4 employing interference fit, guarantee that clip 1 original elasticity can and can not be shifted temperature-sensitive head 4 clampings.
Install after the temperature-sensitive head 4; The air conditioner temperature-sensitive head stationary installation that temperature-sensitive head 4 will be housed again is assembled on the elbow 5 of heat interchanger of air conditioner; The notch that is about to bend pipe folder 3 aligns elbow 5; Stitch along the outside surface of elbow 5 again and press toward the direction of elbow 5, the flange 33 of notch both sides receives outside expansionary force and outwards opens, and makes elbow 5 be pressed into the inside of bend pipe folder 3 and is placed in the elbow host cavity 32.When bend pipe folder 3 was seated, bend pipe pressed from both sides the flange 33 of 3 notch both sides because recovery of elasticity arrives original position, and at this moment, the outside is exposed from first opening 31 in the top of elbow.The effect of flange 33 is edge incised wound elbows 5 of being convenient to assemble and avoid bend pipe folder 3.In the present embodiment; The width of the notch of bend pipe folder 3 presss from both sides 1/2 of 3 cross-sectional circumferential less than bend pipe; And the internal diameter of bend pipe folder 3 is slightly less than the external diameter of elbow 5, is fixed on the elbow 5 thereby bend pipe folder 3 is held, and can come off from elbow 5; And bend pipe folder 3 is interference fit with elbow 5, guarantees that bend pipe folder 3 can clamp elbow 5 and can not be shifted.Particularly, the internal diameter of clip 1 decide according to the outside dimension of temperature-sensitive head 4, and bend pipe presss from both sides 3 internal diameter and then is consistent with the external diameter of heat interchanger refrigerant elbow 5.
With reference to Fig. 4, Fig. 4 is the cut-open view along A-A line among Fig. 3, and temperature-sensitive head 4 is clamped in the clip 1, and elbow 5 is located at the top of bend pipe folder 3.The center cross-sectional of air conditioner temperature-sensitive head stationary installation shown in Figure 4 shows; Because the end that contiguous block 2 links to each other with clip 1 bends to arc; The outside surface of its medial surface and elbow 5 is complementary, and elbow 5 tops are replaced on the medial surface on contiguous block 2 tops, hereinto on the heart xsect; Temperature-sensitive head 4 and elbow 5 mutual butt under the restoring force effect that forms after clip 1 and contiguous block 2 elastic deformations, promptly the bottom of temperature-sensitive head 4 contacts with the top of elbow 5.The part that contiguous block 2 and clip 1 links to each other extend into the gap between temperature-sensitive head 4 and the elbow 5 and closely contacts each other.Temperature-sensitive head 4 and elbow 5 mutual extrusion and fixing under the effect of elasticity tension, elasticity tension is big more, contacts closely more between temperature-sensitive head 4 and the elbow 5, and the temperature parameter of temperature-sensitive head 4 detections is accurate more.Certainly; The air conditioner temperature-sensitive head stationary installation of the utility model is to adopt metal to adopt through the unit clamp punching press, bend and form, and wherein clip 1, contiguous block 2 and bend pipe folder 3 can global formations, also can independent moulding splice assembling again; The heat of elbow 5 can be delivered on the temperature-sensitive head 4 through air conditioner temperature-sensitive head stationary installation; Make temperature-sensitive head 4 can be checked through the temperature of elbow 5, but compared to the mode of temperature-sensitive head 4 with elbow 5 direct contact detection, its effect is poor slightly.
The air conditioner temperature-sensitive head fixture structure of the utility model is simple, easy for installation, and temperature-sensitive head 4 directly contacts with elbow 5, makes the accuracy of temperature detection and stability improve greatly; In addition, the directly impact briquetting of air conditioner temperature-sensitive head stationary installation of the utility model, and also volume is less, and selectable installation site is many, can not cause interference with other structural members, and security is good.
The utility model also provides a kind of air conditioner, and the temperature-sensitive head that is used to detect heat interchanger elbow temperature is fixed on elbow through aforementioned air conditioner temperature-sensitive head stationary installation, and this air conditioner temperature-sensitive head stationary installation is described in detail in front, repeats no more at this.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.Utility model can also have other embodiment except that the foregoing description.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the utility model scope required for protection.
