Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
See figures.1.and.2, Fig. 1 is the structural representation of a preferred embodiment of fixing device for temperature sensing head of air-conditioner of the present invention, and Fig. 2 is the front view of fixing device for temperature sensing head of air-conditioner shown in Fig. 1.Fixing device for temperature sensing head of air-conditioner of the present invention, comprises clip 1, contiguous block 2 and bend pipe folder 3.The cell body that bend pipe folder 3 be 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 the first opening 31.Contiguous block 2 upwards extends from the top of bend pipe folder 3, and its top bends to arc and connects clip 1.Clip 1 is hollow cylinder, and its bottom has along clip 1 the second opening 11, the first openings 31 and the second opening 11 extending longitudinally and is oppositely arranged.The bottom of clip 1 is connected 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, the second opening 11 places of clip 1 are provided with outside flange 13, and bend pipe folder 3 notch both sides are outwardly provided with outside flange 33.
Further, above-mentioned bend pipe folder 3 is semicircle annular, has the xsect of circular arc.The xsect of clip 1 is also circular arc.
With reference to Fig. 3, Fig. 3 is the assembling schematic diagram of fixing device for temperature sensing head of air-conditioner shown in Fig. 1.When assembling, cylindrical temperature-sensitive head 4 is pressed along flange 13 inward by the second opening 11 of clip 1, flange 13 is subject to outside expansionary force and outwards opens, temperature-sensitive head 4 is pressed in temperature-sensitive head host cavity 12, in the time that temperature-sensitive head 4 is seated, flange 13 is because elasticity is recovered original position, and now the bottom of temperature-sensitive head 4 is from the protruding clip 1 of the second opening 11.Flange 13 is set and makes temperature-sensitive head 4 be convenient to assembling and remove, and avoid the edge incised wound temperature-sensitive head 4 of the second opening 11.In the present embodiment, the width of the second opening 11 is less than 1/2 of clip 1 cross-sectional circumferential, so temperature-sensitive head 4 can not come off from the second opening 11, and clip 1 adopts interference fit with temperature-sensitive head 4, guarantees that the original elasticity of clip 1 can clamp temperature-sensitive head 4 and can not be shifted.
After installing temperature-sensitive head 4, again the fixing device for temperature sensing head of air-conditioner that temperature-sensitive head 4 is housed is assembled on the elbow 5 of heat interchanger of air conditioner, notch by bend pipe folder 3 aligns elbow 5, stitch again along the outside surface of elbow 5 and press toward the direction of elbow 5, the flange 33 of notch both sides is subject to outside expansionary force and outwards opens, and makes elbow 5 be pressed into the inside of bend pipe folder 3 and be placed in elbow host cavity 32.In the time that bend pipe folder 3 is seated, bend pipe presss from both sides flange 33 position original because elasticity returns to of 3 notch both sides, and now, outside is exposed from the first opening 31 in the top of elbow.The effect of flange 33 is edge incised wound elbows 5 of being convenient to assembling and avoiding bend pipe folder 3.In the present embodiment, the width of the notch of bend pipe folder 3 is less than bend pipe and presss from both sides 1/2 of 3 cross-sectional circumferential, and the internal diameter of bend pipe folder 3 is slightly less than the external diameter of elbow 5, thereby bend pipe folder 3 is held to be fixed on elbow 5, and can not come off from elbow 5, and bend pipe folder 3 is interference fit with elbow 5, guarantee that bend pipe folder 3 can clamp elbow 5 and can not be shifted.Particularly, the internal diameter of clip 1 is determined according to the outside dimension of temperature-sensitive head 4, and the internal diameter of bend pipe folder 3 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 in Fig. 3, and temperature-sensitive head 4 is clamped in clip 1, and elbow 5 is located at the top of bend pipe folder 3.The center cross-sectional of fixing device for temperature sensing head of air-conditioner shown in Fig. 4 shows, because contiguous block 2 bends to arc with one end that clip 1 is connected, the outside surface of its medial surface and elbow 5 matches, elbow 5 tops are supported on the medial surface on contiguous block 2 tops, hereinto on heart xsect, mutual butt under the restoring force effect that temperature-sensitive head 4 and elbow 5 form after clip 1 and contiguous block 2 elastic deformations, the bottom of temperature-sensitive head 4 contacts with the top of elbow 5.The part that contiguous block 2 is connected with clip 1 extend into gap and the mutual close contact between temperature-sensitive head 4 and elbow 5.Temperature-sensitive head 4 extrudes and fixes under the effect of elasticity tension mutually with elbow 5, and elasticity tension is larger, between temperature-sensitive head 4 and elbow 5, contacts closelyr, and the temperature parameter that temperature-sensitive head 4 detects is more accurate.Certainly, fixing device for temperature sensing head of air-conditioner of the present invention is to adopt metal to adopt by unit clamp punching press, bend and form, wherein clip 1, contiguous block 2 and bend pipe folder 3 can global formations, also can independent moulding splice again assembling, the heat of elbow 5 can be delivered on temperature-sensitive head 4 by fixing device for temperature sensing head of air-conditioner, make temperature-sensitive head 4 can be checked through the temperature of elbow 5, but compared to temperature-sensitive head 4 mode with elbow 5 direct contact detection, its effect is slightly poor.
Fixing device for temperature sensing head of air-conditioner of the present invention is simple in structure, easy for installation, and temperature-sensitive head 4 directly contacts with elbow 5, and the Stability and veracity of temperature detection is improved greatly; In addition, directly impact briquetting of fixing device for temperature sensing head of air-conditioner of the present invention, and small volume, selectable installation site is many, can not cause interference with other structural members, and security is good.
The present invention also provides a kind of air conditioner, is fixed on elbow by aforementioned fixing device for temperature sensing head of air-conditioner for detection of the temperature-sensitive head of heat interchanger elbow temperature, and this fixing device for temperature sensing head of air-conditioner is described in detail above, does not repeat them here.
Below be only concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.Invention can also have other embodiment in addition to the implementation.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the present invention's scope required for protection.
