Refrigerant plays a vital role in air conditioning. When the refrigerant in the air conditioner needs to be replaced, when the air conditioner breaks down and needs to be repaired, or when the air conditioner is scrapped, the refrigerant in the air conditioner needs to be recovered to avoid the refrigerant in the air conditioner being released into the atmosphere and causing damage to the environment. At the same time, the refrigerant can be reused after recovery, saving costs and reducing energy consumption.

[0003] The invention patent with publication number CN117109208B discloses an air conditioner refrigerant recovery device, including: a recovery main pipe, a quick recovery mechanism, a waist-shaped receiving roller, a rolling wheel and a locking connection mechanism. The above application document accelerates the flow speed of the refrigerant in the delivery pipe by setting a quick recovery mechanism. It uses a single-direction rolling method to squeeze the delivery pipe. During the long-term rolling process, the transverse bend of the delivery pipe is prone to rupture, which will cause refrigerant leakage. Summary of the invention

[0004] The present invention solves the problem that the existing technology accelerates the flow rate of the refrigerant in the delivery pipe by setting a rapid recovery mechanism. The delivery pipe is squeezed by rolling in a single direction. During the long rolling process, the transverse bend of the delivery pipe is prone to rupture, which will cause the refrigerant to leak. To this end, the present invention proposes an energy-saving refrigeration unit with a refrigerant recovery function, which can roll the delivery pipe at multiple angles to prevent damage to the delivery pipe caused by rolling at a single angle, and can protect the delivery pipe.

[0005] To achieve the above-mentioned object, the present application provides an energy-saving refrigeration unit with a refrigerant recovery function, comprising a refrigeration machine body, wherein the refrigeration machine body includes an evaporator and a condenser;

[0010] Preferably, each group of the rolling assemblies has two first hydraulic rods corresponding to the two first movable rods, and each group of the rolling assemblies has eight second hydraulic rods, and each two second hydraulic rods form a group. When the second hydraulic rods are squeezed, the liquid pressure in the multi-pass hydraulic chamber is changed, so that the first hydraulic rod is extended, thereby pushing the first movable rod to move, and the height of the squeezed ball is controlled by the movement of the first movable rod.

By arranging the linkage components, the waist-shaped receiving roller can move up and down synchronously with the squeezing ball, so that during the resetting process of the equipment, the waist-shaped receiving roller and the squeezing ball are separated from the conveying pipe, thereby reducing the squeezing damage to the conveying pipe.

[0013] Preferably, the first gas pressure rod is fixed to the side of the first movable rod, and the second gas pressure rod is fixed to the side of the second movable rod. The movement of the second gas pressure rod is controlled by the movement of the first gas pressure rod, so when the first movable rod drives the squeezing ball to move, the waist-shaped receiving roller can be driven to move synchronously by the second movable rod.

[0017] (3) The present application sets a linkage component so that the waist-shaped receiving roller can move up and down synchronously with the squeezing ball. During the resetting process of the equipment, the waist-shaped receiving roller, the squeezing ball and the conveying pipe can be separated, thereby reducing the squeezing damage to the conveying pipe.

[0043] See also Figure 1-Figure 12 , this embodiment provides an energy-saving refrigeration unit with a refrigerant recovery function, including a refrigeration machine body 100, wherein the refrigeration machine body 100 includes an evaporator and a condenser 300;

[0044] The refrigerator body 100 is internally equipped with a refrigerant recovery assembly 400 connected to the condenser 300.

The side of the delivery pipe 700 is equipped with a control valve 800.

[0045] The quick recovery component 900 includes a rectangular bracket 910 and a rolling component. Two symmetrically arranged linear motors 920 are installed on both sides of the top of the rectangular bracket 910. The bottom of the linear motor 920 is equipped with a driving wheel 960 controlled by an induction motor. The four corners of the bottom of the linear motor 920 are fixed with a driving rod 970. A plurality of roller brackets 940 for supporting an annular bracket 950 are slidably connected to the inner wall groove 930 of the rectangular bracket 910. The induction motor connected to the driving wheel 960 is slidably connected to the bottom of the linear motor 920, and the driving wheel 960 is connected to the annular groove outside the annular bracket 950.

[0046] The rolling assembly is provided with two groups, and the rolling assembly includes an annular bracket 950, and an annular groove is provided on the outside of the annular bracket 950 and connected with a plurality of the roller brackets 940 through the annular groove. When the linear motor 920 moves the annular bracket 950 through the driving rod 970, since the linear motor 920 moves back and forth, it is necessary to set the induction motor and the linear motor 920 in a sliding connection mode, and at the same time, the induction motor controls the driving wheel 960 to rotate by sensing the distance between the induction motor and the rectangular bracket 910, and each time the driving wheel 960 rotates once, the annular bracket 950 is controlled to rotate forty-five degrees;

[0047] exist Figure 2 The state is the initial state of the device, and when the linear motor 920 moves from left to right, the driving rod 970 at the bottom of the linear motor 920 will push the annular bracket 950 to move;

[0048] There are four driving rods 970 in total, and every two driving rods 970 form a group and are symmetrically fixed at the bottom of the linear motor 920. Two driving rods 970 are located on one side of the annular bracket 950, and the other two driving rods 970 are located on the other side of the annular bracket 950. There is a certain clearance between the two groups of driving rods 970. When the linear motor 920 reciprocates and alternates, the driving rods 970 will have a certain moving range, giving the induction motor a certain working time. During the alternating process, the driving wheel 960 is rotated by the induction motor to control the rotation of the annular bracket 950;

[0049] Two hollow rods 9100 are symmetrically fixed inside the annular bracket 950 through two connecting rods 990. The first movable rods 9110 are slidably connected inside the two hollow rods 9100. A spring for resetting is fixed between the hollow rods 9100 and the first movable rods 9110. When the first movable rods 9110 are squeezed downward, the spring will be compressed. Then, in the absence of external force, the first movable rods 9110 are reset by the spring. A first positioning rod 9120 is fixed between the two first movable rods 9110. A squeezing ball 913 is rotatably connected to the first positioning rod 9120. 0, two connecting blocks 9140 are fixed inside the annular bracket 950, and the two connecting blocks 9140 are slidably connected with the second movable rod 9150 through track grooves opened on the outer walls thereof, and a spring for resetting is fixed between the connecting block 9140 and the second movable rod 9150, and the spring is compressed when the second movable rod 9150 is squeezed downward, and then the second movable rod 9150 is reset by the spring in the absence of external force, and a second positioning rod 9160 is fixed between the two second movable rods 9150, and a waist-shaped receiving roller 9170 is rotatably connected to the second positioning rod 9160.

[0050] A multi-channel hydraulic bin 980 is fixed inside the annular bracket 950, and a first hydraulic rod 9180 for pushing the first movable rod 9110 and a second hydraulic rod 9190 for changing the liquid pressure in the multi-channel hydraulic bin 980 are slidably connected inside the multi-channel hydraulic bin 980. Two first hydraulic rods 9180 are provided in each group of the rolling assemblies, and the two first movable rods 9110 are corresponding to each other. Eight second hydraulic rods 9190 are provided in each group of the rolling assemblies, and every two second hydraulic rods 9190 form a group. When the second hydraulic rod 9190 is squeezed, the liquid pressure in the multi-channel hydraulic bin 980 is changed, so that the first hydraulic rod 9180 is extended, thereby pushing the first movable rod 9110 to move, and the height of the squeezing ball 9130 is controlled by the movement of the first movable rod 9110.

[0051] Each group of rolling components is provided with two groups of linkage components, each group of linkage components includes a pneumatic chamber 9200, one end of the interior of the pneumatic chamber 9200 is slidably connected to a first pneumatic rod 9210, and the other end of the interior of the pneumatic chamber 9200 is slidably connected to a second pneumatic rod 9220, the first pneumatic rod 9210 is fixed to the side of the first movable rod 9110, and the second pneumatic rod 9220 is fixed to the side of the second movable rod 9150. By setting the linkage components, the waist-shaped bearing The roller 9170 can move up and down synchronously with the squeezing ball 9130, so that during the resetting process of the equipment, the waist-shaped receiving roller 9170, the squeezing ball 9130 and the conveying tube 700 can be separated, thereby reducing the squeezing damage to the conveying tube 700. At the same time, the movement of the second pneumatic rod 9220 is controlled by the movement of the first pneumatic rod 9210. Therefore, when the first movable rod 9110 drives the squeezing ball 9130 to move, the waist-shaped receiving roller 9170 can be synchronously driven to move by the second movable rod 9150.

[0052] The present application recovers the refrigerant in the condenser 300 by setting a refrigerant recovery component 400. At the same time, in order to prevent the refrigerant from remaining in the delivery pipe 700, a quick recovery component 900 is set to squeeze the delivery pipe 700 to clean the residual refrigerant in the delivery pipe 700. At the same time, the rolling component in the present application can rotate during operation, thereby changing the squeezing angle of the delivery pipe 700, which can prevent the delivery pipe 700 from being broken due to unidirectional squeezing.

[0053] When the above device is used, after the refrigerator body 100 stops working, the control valve 800 and the pressure valve 600 are opened to recover the refrigerant in the condenser 300 to the recovery tank 500 through the delivery pipe 700. After the initial recovery is completed, the control valve 800 is closed, and then the two linear motors 920 are synchronously turned on.

[0054] exist Figure 2In the state, the linear motor 920 will move from left to right on the rectangular bracket 910 after it is turned on. When the linear motor 920 moves, the first group of driving rods 970 at the bottom thereof will squeeze the two second hydraulic rods 9190 of the first group until they are fitted with the annular bracket 950. At this time, after the two second hydraulic rods 9190 are squeezed, the liquid pressure in the multi-pass hydraulic warehouse 980 will increase, so that the two first hydraulic rods 9180 will move. At this time, the two first hydraulic rods 9180 will simultaneously push the two first movable rods 9110 to move downward. At this time, due to the descent of the two first movable rods 9110, the squeezing ball 9130 will be driven to move downward through the first positioning rod 9120. At the same time, as the two first movable rods 9110 move downward, the two first pneumatic rods will be driven at the same time. 9210 moves downward, thereby increasing the gas pressure in the air pressure chamber 9200, so that the second air pressure rod 9220 moves upward, and the two second air pressure rods 9220 simultaneously push the two second movable rods 9150 to move upward. When the two second movable rods 9150 move upward, the second positioning rod 9160 drives the waist-shaped receiving roller 9170 to move upward, and forms an extrusion effect on the delivery pipe 700 by cooperating with the extrusion ball 9130. As the linear motor 920 moves, the driving rod 970 at its bottom will push the annular bracket 950 and its internal structure to move from left to right. Through the extrusion effect generated by the extrusion ball 9130 and the waist-shaped receiving roller 9170, the refrigerant in the delivery pipe 700 is squeezed into the recovery tank 500 to prevent the refrigerant from remaining in the delivery pipe 700;

[0055] When the linear motor 920 approaches the rectangular bracket 910 on the right, it moves in the reverse direction. When the linear motor 920 moves in the reverse direction, the first set of driving rods 970 separates from the annular bracket 950 and the second hydraulic rod 9190. At this time, since a spring piece for resetting is fixed between the hollow rod 9100 and the first movable rod 9110, the spring piece will be compressed when the first movable rod 9110 is pressed downward, and then the first movable rod 9110 is reset by the spring piece without the action of external force. Therefore, the two first movable rods 91 10 resets and drives the squeezing ball 9130 to reset upwards. Then, since a spring for resetting is fixed between the connecting block 9140 and the second movable rod 9150, the spring will be compressed when the second movable rod 9150 is squeezed downwards. Then, when there is no external force, the second movable rod 9150 is reset by the spring. Therefore, the two second movable rods 9150 reset downwards and drive the waist-shaped receiving roller 9170 to move downwards. At this time, the waist-shaped receiving roller 9170 and the squeezing ball 9130 are separated from the conveying pipe 700.

[0056] At this time, the induction motor senses the right side of the rectangular bracket 910 and starts the driving wheel 960 to rotate. Each time the driving wheel 960 rotates, the annular bracket 950 is controlled to rotate forty-five degrees (after each rotation, another group of the four groups of second hydraulic rods 9190 will replace the group of second hydraulic rods 9190 that was initially in contact with the driving rod 970). Then, with the reset movement of the linear motor 920, the annular bracket 950 and its internal structure will be driven to return to the initial state. During this process, the waist-shaped receiving roller 9170 and the squeezing ball 9130 do not contact the conveying tube 700, so the conveying tube 700 will not be squeezed. At the same time, the angle between the waist-shaped receiving roller 9170, the squeezing ball 9130 and the conveying tube 700 is changed. In subsequent use, the squeezing area of ​​the conveying tube 700 is changed. In this way, damage caused by squeezing in a single direction can be avoided.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
