Description

Technical Field

[0001] The utility model belongs to the technical field of liquid storage tanks, and in particular relates to a protective device for a high-pressure liquid storage tank of an air conditioner. Background Art

[0002] In air conditioning systems, the high-pressure liquid receiver is a key component. Its primary function is to store the liquid refrigerant flowing out of the condenser and provide the appropriate amount of refrigerant to the evaporator when needed. However, during the operation of the air conditioning system, various reasons, such as fluctuations in condenser temperature and pressure, uneven distribution of refrigerant in the system, may cause an abnormal increase in liquid refrigerant or refrigeration oil in the receiver. If this liquid substance enters the receiver along with the gas, it may damage the receiver and even affect the compressor connected to the receiver, causing liquid hammer in the compressor, thereby reducing the performance and life of the entire air conditioning system.

[0003] Traditional air conditioning systems have limited protection measures for liquid storage tanks, relying primarily on pre-installed safety valves and pressure relief mechanisms. While these measures can protect the liquid storage tank and compressor to a certain extent, they typically only take effect after a problem has occurred and cannot effectively prevent problems before they occur. Furthermore, these measures cannot adjust to changes in flow within the intake pipe in real time, and therefore cannot effectively prevent abnormal increases in liquid refrigerant or refrigeration oil.

[0004] For example, in existing safety valve designs, when system pressure exceeds a set value, the valve opens to release pressure. However, this passive protection method cannot respond promptly to flow changes. Additionally, some systems may use filters to reduce the amount of liquid entering the storage tank. However, these filters typically cannot precisely control flow and may become clogged after long-term use, affecting system performance.

[0005] In view of the above problems, the present invention proposes a protective device for an air-conditioning high-pressure liquid storage tank to avoid the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a protection device for a high-pressure liquid storage tank of an air conditioner, which can intervene before a problem occurs, thereby ensuring the stable operation of the air conditioning system and extending the service life of the equipment.

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0026] like Figure 1-4 As shown, a protective device for a high-pressure liquid storage tank of an air conditioner comprises a liquid storage tank 1, on the top of which an air inlet pipe 2 and an air outlet tank 3 are installed;

[0027] The liquid storage tank 1 can take in air through the air inlet pipe 2 and discharge air through the air outlet tank 3;

[0028] The inside of the air intake pipe 2 is provided with a baffle 14, and the outside of the air intake pipe 2 and the top of the baffle 14 are provided with a motor 4. Figure 2 , a shell 5 is installed on the outside of the intake pipe 2 and on the outside of the motor 4. Through the arrangement of the shell 5, the shell 5 can protect the motor 4 to prevent the motor 4 from malfunctioning due to external force. The output end of the motor 4 passes through the intake pipe 2 and is connected to the baffle plate 14. When the intake of the intake pipe 2 is controlled, the motor 4 can be driven, and then the output end of the motor 4 drives the baffle plate 14 to rotate. Through the rotation of the baffle plate 14, the gap between the intake pipe 2 and the baffle plate 14 can be adjusted, thereby adjusting the flow rate of the gas passing through the intake pipe 2, and preventing too much liquid refrigerant or refrigeration oil from entering the liquid storage tank 1 (when the flow rate is too large, the liquid refrigerant or refrigeration oil may also enter the intake pipe 2 and the liquid storage tank 1 together with the gas), protecting the liquid storage tank 1, thereby indirectly protecting the compressor connected to the liquid storage tank 1, and preventing the compressor from liquid hammer;

[0029] A branch pipe 6 is further provided on the outside of the air inlet pipe 2 , and a driving mechanism is installed inside the branch pipe 6 . The driving mechanism is used to drive the output end of the motor 4 to drive the blocking plate 14 to rotate at an angle.

[0030] Refer to the attached Figure 4 , the driving mechanism includes a blocking groove 7 and a mounting plate 15 fixed to the inside of the branch pipe 6, and a hole is provided in the mounting plate 15 so that the gas can pass through the mounting plate 15 through the hole. The interior of the mounting plate 15 is slidably connected to a sliding rod 9, and an abutting ball 8 is fixed to one end of the sliding rod 9 close to the blocking groove 7. The abutting ball 8 is hollow. Through this arrangement, when the abutting ball 8 is attracted by the solenoid valve 13, its resistance can be minimized, so that the solenoid valve 13 can adsorb it, and the side of the abutting ball 8 close to the blocking groove 7 abuts against the inner wall of the blocking groove 7. A spring 10 is assembled between the abutting ball 8 and the mounting plate 15 and on the outside of the sliding rod 9;

[0031] A pressing strip 11 is fixed to one end of the sliding rod 9 away from the abutting ball 8 , and a plurality of start buttons 12 are provided on the inner wall of the branch pipe 6 , and the pressing strip 11 and the start buttons 12 abut against each other.

[0032] When air is taken in by the intake pipe 2, the gas will enter the liquid storage tank 1 through the intake pipe 2. When the gas intake is too much, part of the gas will enter the branch pipe 6 due to the oblique setting of the blocking plate 14. After entering the branch pipe 6, the gas will squeeze the abutment ball 8 and make the abutment ball 8 break away from the contact between the blocking groove 7, so that some gas will enter the branch pipe 6 around the mounting plate 15, and then enter the intake pipe 2 again through the branch pipe 6.

[0033] When the gas squeezes the abutment ball 8, the abutment ball 8 compresses the spring 10 and drives the sliding rod 9 to move. When the gas is less, the squeezing force is lower. A controller is also installed on the intake pipe 2. The controller is electrically connected to the start button 12 and the blocking plate 14. At this time, the pressing bar 11 contacts the first start button 12. At this time, the start button 12 controls the motor 4 through the controller to start and drives the blocking plate 14 to rotate to a smaller angle (the initial angle of the blocking plate 14 is parallel to the intake pipe 2, which does not block the gas in the intake pipe 2, and is 10-20 degrees), slightly blocking the gas.

[0034] When the pressing bar 11 moves to contact the second start button 12, a signal can be transmitted to the controller through the start button 12, and the controller drives the motor 4 to rotate the blocking plate 14 to a medium angle of 20-40 degrees;

[0035] When the pressing bar 11 moves to release the third start button 12, the start button 12 transmits a signal to the controller, and the controller drives the motor 4 to rotate the blocking plate 14 to a larger angle of 40-70 degrees;

[0036] In this way, when the gas moves more violently, the blocking plate 14 can block the gas in the air inlet pipe 2 to a certain extent, reducing the speed of gas transmission, thereby minimizing the entry of liquid refrigerant or refrigeration oil into the liquid storage tank 1.

[0037] According to the above structure, at least one solenoid valve 13 is provided on the side of the mounting plate 15 close to the abutting ball 8. The material of the abutting ball 8 is a material that is magnetically attracted to the solenoid valve 13, and the magnetic end of the solenoid valve 13 faces the abutting ball 8. When there is not too much gas in the branch pipe 6, the solenoid valve 13 can be driven to make the solenoid valve 13 adsorb the abutting ball 8. The material of the abutting ball 8 can be iron, and thus can be adsorbed by the solenoid valve 13, and the material of the abutting ball 8 can also be a magnet, and the adsorption end of the solenoid valve 13 is opposite to the magnetic pole of the abutting ball 8, so that when the solenoid valve 13 is driven, it can adsorb the abutting ball 8. After adsorption, the abutting ball 8 moves toward the solenoid valve 13, so that the gas remaining in the branch pipe 6 can move back to the intake pipe 2 through the blocking groove 7 and the mounting plate 15, thereby reducing the residual gas in the branch pipe 6.

[0038] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
