Description
One, technical field
The present invention relates to air conditioner, relate in particular to a kind of indoor and outdoor coolant tubing connector of air conditioner.
Two, background technique
Air conditioner is will be by compressor, condensing machine, expansion gear, vaporizer circuit refrigerant, carry out heat exchange with air by vaporizer after, interior space air is carried out a kind of device that changes in temperature are regulated.The structure of air conditioner comprises, outdoor unit that constitutes by compressor, condensing machine and expansion gear and the indoor set that constitutes by fan and vaporizer, outdoor unit and indoor set between interconnect by coolant piping.
Air conditioner mainly comprises the integral air conditioner and the separate type air conditioner of window formula, the kind of split type air conditioner can be divided into according to the position that is provided with of indoor set, and the vertical type air conditioner, the suspension that uprightly are placed on indoor use are installed in the wall air conditioner that uses on the indoor wall and are installed in the ceiling board air conditioner machine that use at indoor top.In the integral air conditioner, the outdoor heat converter that is configured in the outdoor is connected by refrigerant piping (coolant piping) with the indoor heat converter that is configured in the indoor side, each heat exchanger is controlled to condenser and the vaporizer that plays a part refrigeration agent, to freeze or to heat operation; In the separate type air conditioner, the outdoor heat converter that is configured in outdoor unit is connected by refrigerant piping (coolant piping) with the indoor heat converter that is configured in indoor set, each heat exchanger is controlled to condenser and the vaporizer that plays a part refrigeration agent, to freeze or to heat operation.Integral air conditioner all is connected by connecting head with refrigerant piping (coolant piping) connection part in the separate type air conditioner, and this connecting head must guarantee that refrigeration agent do not reveal, and air conditioner is normally moved.
In integral air conditioner and the separate type air conditioner, outdoor (machine) disposes the outdoor fan that can produce air stream, introduces ambient air by this outdoor fan, carries out heat exchange between refrigeration agent by outdoor heat converter inside and air; Equally, indoor side (machine) disposes the indoor fan that can produce air stream, by this indoor fan indoor air sucked, and carry out heat exchange between refrigeration agent by indoor heat converter inside and air.When air conditioner is worked, driving along with fan, suck indoor air by the air sucking mouth, during inhaled air process indoor heat exchanger, be cooled or heat by the heat exchange action with refrigerant, the driving by fan is then flowed along the radial direction of fan, be discharged to indoorly through exhaust port at last, reach the purpose of indoor air being carried out cold and hot adjusting.
Consult Fig. 1, shown in Figure 2, existing air conditioner indoor and outdoor coolant tubing (refrigerant piping) connecting head, it is a hollow tube body 2, body 2 outer surface are provided with the screw section 21 that screws togather for nut, body 2 ends 22 are arranged to and the coolant piping 1 outer tubaeform mouth of pipe 11 corresponding inside trumpet shapes, after the tubaeform mouth of pipe 11 is set in the end 22 of connecting head 2 inside trumpet shapes outside the coolant piping 1, fastening force by tightening nut 3, the outer tubaeform mouth of pipe 11 of coolant piping is fitted fully with the end 22 of connecting head 2 inside trumpet shapes, reach the effect of sealing and fixing, do not reveal to guarantee the refrigeration agent in the coolant piping 1.But, existing air conditioner coolant piping (refrigerant piping) connecting head, it is the sealing and fixing that realizes coolant piping and connecting head by the fastening force of tightening nut 3, and the fastening force of tightening nut 3 is finished by manual type, therefore in fastening, if it is firmly excessive, then may cause the distortion (as shown in Figure 3) of the coolant piping 1 that copper material makes, cause the fracture of coolant piping 1 straight tube and outer horn mouth joint, cause the leakage of refrigeration agent, air conditioner is in the course of the work owing to the continuous seepage of refrigeration agent from the joint, the phenomenon that refrigeration agent occurs lacking of a specified duration causes the decline of refrigerating capacity, influences the service behaviour of air conditioner, shorten the working life of air conditioner, therefore pending improvement is arranged.
Three, summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that existing product exists, and provide a kind of indoor and outdoor coolant tubing connector of air conditioner, it is cut on the inside trumpet body of connecting head end and establishes the inclined-plane that inwardly concaves, utilize this inclined-plane that the area of contact of the outer tubaeform mouth of pipe of coolant piping and connecting head end inside trumpet body is strengthened, the limited degree of deformation of control coolant piping, improve the effect that is connected of coolant piping and connecting head, effectively reduce the seepage discharge of refrigeration agent, guarantee the refrigerating capacity and the service behaviour of air conditioner, prolong the working life of air conditioner.
The objective of the invention is to realize by following technological scheme.
Indoor and outdoor coolant tubing connector of air conditioner of the present invention comprises connecting head, and it is a hollow tube, and the outer surface of tube body place is provided with the screw section that screws togather for nut, and the body end is arranged to and the outer corresponding inside trumpet shape of the tubaeform mouth of pipe of coolant piping; It is characterized in that: cut on the inside trumpet body outer side surface of described connecting head end and establish the inclined-plane that inwardly concaves.
Aforesaid indoor and outdoor coolant tubing connector of air conditioner, wherein the length on inclined-plane is equal to, or greater than the outer domatic length of the tubaeform mouth of pipe of coolant piping.
Aforesaid indoor and outdoor coolant tubing connector of air conditioner, wherein chamfer length is 0.05 to 0.15mm greater than the scope of the outer domatic length of the tubaeform mouth of pipe of coolant piping.
Aforesaid indoor and outdoor coolant tubing connector of air conditioner, wherein the degree of depth that inwardly concaves of inclined-plane equals the wall thickness of the outer tubaeform mouth of pipe of coolant piping.
Aforesaid indoor and outdoor coolant tubing connector of air conditioner, wherein the inclination on inclined-plane equals the outer domatic inclination of the tubaeform mouth of pipe of coolant piping.
The beneficial effect of indoor and outdoor coolant tubing connector of air conditioner of the present invention is, it is cut on the inside trumpet body outer side surface of connecting head end and establishes the inclined-plane that inwardly concaves, the length on this inclined-plane is equal to, or greater than the outer domatic length of the tubaeform mouth of pipe of coolant piping, the inclination on inclined-plane equals the outer domatic inclination of the tubaeform mouth of pipe of coolant piping, the degree of depth that the inclined-plane inwardly concaves equals the wall thickness of the outer tubaeform mouth of pipe of coolant piping, utilize this inclined-plane that the area of contact of outer horn opening of coolant piping and connecting head end inside trumpet body is strengthened, can control simultaneously the limited degree of deformation of coolant piping, avoid the outer tubaeform mouth of pipe and straight tube joint fracture to occur, therefore can improve the effect that is connected of coolant piping and connecting head, effectively reduce the seepage discharge of refrigeration agent, guarantee the refrigerating capacity and the service behaviour of air conditioner, prolong the working life of air conditioner.
