However, the existing air conditioner refrigerant piping (refrigerant piping) joints use the fastening force of the fastening nut 3 to realize the sealing and fixing of the refrigerant piping and the joint, and the fastening force of the fastening nut 3 is manual. Therefore, in the fastening, if the force is too large, it may cause the deformation of the refrigerant piping 1 made of copper (such as image 3 As shown), resulting in the rupture of the connection between the straight pipe of the refrigerant pipe 1 and the outer bell mouth, resulting in leakage of the refrigerant. During the operation of the air conditioner, due to the continuous leakage of the refrigerant from the connection, the phenomenon of lack of refrigerant occurs over time. It leads to the decline of refrigeration capacity, affects the working performance of the air conditioner, and shortens the service life of the air conditioner, so it needs to be improved

The invention provides a connector of an indoor and outdoor coolant matched tube of an air conditioner. The connector comprises the connector which is a hollow tube body; the outer surface of the tube body is provided with a thread part for a nut to screw; and the end part of the tube body is arranged into an inner horn shape corresponding to an outer horn-shaped nozzle of the coolant matched tube. The connector has the improvement that: the lateral surface of an inner horn-shaped body of the end part of the connector is provided with an inward concave bevel; and the connector utilizes the bevel to enlarge the contact area between the outer horn-shaped nozzle pf the coolant matched tube and the inner horn-shaped body of the end part of the connector, controls the deformation limit of the coolant matched tube, improves the effect of connection between the coolant matched tube and the connector, effectively reduces the seepage discharge of a refrigerant, ensures the refrigerating capacity and the working performance of the air conditioner and prolongs the service life of the air conditioner.
Description
1. Technical field [0001] The invention relates to an air conditioner, in particular to an indoor and outdoor refrigerant piping connector of the air conditioner. 2. Background technology [0002] The air conditioner is a device that cools and warms the air in the indoor space after exchanging heat between the refrigerant circulating through the compressor, condenser, expansion device, and evaporator and the air passing through the evaporator. The structure of the air conditioner includes an outdoor unit composed of a compressor, a condenser, and an expansion device, and an indoor unit composed of a fan and an evaporator. The outdoor unit and the indoor unit are connected to each other through refrigerant piping. [0003] Air conditioners mainly include window-type integrated air conditioners and split-type air conditioners. The types of split air conditioners can be divided according to the installation position of the indoor unit. The wall-mounted air conditioner used and...
